The quality of a street is integral to the vitality. However, most efforts have focused on the requirements of cars resulting in the loss many qualities. A successful street is related to the needs and expectations of pedestrians. The amount of activity held in a place is one of the measures of vitality; hence the meaning of a vital street may be the result of a number of people engaged in various activities meeting their needs and expectations. Consequently, it varies from one city to another. This research focuses on vitality in commercial streets. It studies commercial streets in the Egyptian context, which have developed into a chaotic environment due to inefficiency and high-density activities. The first part identifies the meaning of vitality in the frame of its physical, social and economic dimensions, then determines the methods used in measuring vitality across commercial streets. Secondly, an application on one of the most important commercial streets in Alexandria ‘El-Attareen’ street is chosen as a case study to measure its vitality. The study contributes to a greater understanding of how theories on vital urban life contribute to the development of vital commercial streets in the Egyptian and similar contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=footfall%20measurement" title="footfall measurement">footfall measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=vitality" title=" vitality"> vitality</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20commercial%20streets" title=" urban commercial streets"> urban commercial streets</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20factor" title=" yield factor"> yield factor</a> </p> <a href="https://publications.waset.org/abstracts/55319/urban-vitality-methods-for-measuring-vitality-in-egypts-commercial-streets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55319.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">836</span> Review of Urban Vitality in China: Exploring the Theoretical Framework, Characteristics, and Assessment Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Wei">Dong Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Wu%20Jinxiu"> Wu Jinxiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As China's urban construction enters a new phase of 'stock optimization,' the key point of urban development has shifted to the development and reuse of existing public space. However, cities still face a series of challenges, such as the shortage of space quantity and insufficient space quality, which indirectly affect urban vitality. A review of the vitality of urban public space will significantly contribute to optimizing the quality of the urban built environment. It firstly analyses the research hotspots of urban vitality at home and abroad, based on a semi-systematic literature review. Then this paper summarizes the theoretical definitions of the vitality of urban public space and sorts out the influencing factors from the perspectives of society, environment, and users. Lastly, the paper concludes with the mainstream quantitative and evaluation methods, such as linear evaluation and integrated evaluation. This paper renders a multi-theoretical perspective to understand the characteristics and evaluation system of the vitality of public space, which helps to acknowledge the dynamic relationship between users, urban environment, and vitality.

The street is a basic public product and an important public space in the city, and commerce along the street is an important space for people to consume in the "experience era". Therefore, in this way, it is particularly important to create the vitality of the gray space along the street. From the perspective of vitality construction, this paper takes Sha Zheng Street in Chongqing as the empirical object, combined with the theoretical knowledge of behavioral architecture, and based on the current situation of the commercial gray space along Sha Zheng Street, this paper explores the influence factors and the constraints behind the spatial vitality and then puts forward a general strategy to improve the spatial vitality of the commercial gray space along the street. The author hopes that through the exploration of the vitality of commercial gray space along the street, environmental design can be introduced into the integrated design vision of the urban public environment, and the urban designers can be inspired to create a street environment with a living atmosphere with a small start. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vitality%20creation" title="vitality creation">vitality creation</a>, <a href="https://publications.waset.org/abstracts/search?q=gray%20space" title=" gray space"> gray space</a>, <a href="https://publications.waset.org/abstracts/search?q=street%20commerce" title=" street commerce"> street commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=sha%20zheng%20street" title=" sha zheng street"> sha zheng street</a> </p> <a href="https://publications.waset.org/abstracts/170660/optimization-of-commercial-gray-space-along-the-street-from-the-perspective-of-vitality-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">833</span> In vitro Effects of Salvia officinalis on Bovine Spermatozoa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20Botman"> Boris Botman</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Halen%C3%A1r"> Marek Halenár</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%C3%A1%C5%A1%20Slanina"> Tomáš Slanina</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Luk%C3%A1%C4%8D"> Norbert Lukáč</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <em>In vitro</em> storage and processing of animal semen represents a risk factor to spermatozoa vitality, potentially leading to reduced fertility. A variety of substances isolated from natural sources may exhibit protective or antioxidant properties on the spermatozoon, thus extending the lifespan of stored ejaculates. This study compared the ability of different concentrations of the <em>Salvia officinalis</em> extract on the motility, mitochondrial activity, viability and reactive oxygen species (ROS) production by bovine spermatozoa during different time periods (0, 2, 6 and 24 h) of <em>in vitro</em> culture. Spermatozoa motility was assessed using the Computer-assisted sperm analysis (CASA) system. Cell viability was examined using the metabolic activity MTT assay, the eosin-nigrosin staining technique was used to evaluate the sperm viability and ROS generation was quantified using luminometry. The CASA analysis revealed that the motility in the experimental groups supplemented with 0.5-2 µg/mL <em>Salvia</em> extract was significantly lower in comparison with the control (P<0.05; Time 24 h). At the same time, a long-term exposure of spermatozoa to concentrations ranging between 0.05 µg/mL and 2 µg/mL had a negative impact on the mitochondrial metabolism (P<0.05; Time 24 h). The viability staining revealed that 0.001-1 µg/mL <em>Salvia</em> extract had no effects on bovine male gametes, however 2 µg/mL <em>Salvia</em> had a persisting negative effect on spermatozoa (P<0.05). Furthermore 0.05-2 µg/mL <em>Salvia</em> exhibited an immediate ROS-promoting effect on the sperm culture (P>0.05; Time 0 h and 2 h), which remained significant throughout the entire <em>in vitro</em> culture (P<0.05; Time 24 h). Our results point out to the necessity to examine specific effects the biomolecules present in <em>Salvia officinalis</em> may have individually or collectively on the <em>in vitro</em> sperm vitality and oxidative profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulls" title="bulls">bulls</a>, <a href="https://publications.waset.org/abstracts/search?q=CASA" title=" CASA"> CASA</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT%20test" title=" MTT test"> MTT test</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a>, <a href="https://publications.waset.org/abstracts/search?q=sage" title=" sage"> sage</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvia%20officinalis" title=" Salvia officinalis"> Salvia officinalis</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/56562/in-vitro-effects-of-salvia-officinalis-on-bovine-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56562.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">832</span> In vitro Effects of Berberine on the Vitality and Oxidative Profile of Bovine Spermatozoa </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Greifov%C3%A1"> Hana Greifová</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Ivani%C4%8D"> Peter Ivanič</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Luk%C3%A1%C4%8D"> Norbert Lukáč </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to evaluate the dose- and time-dependent <em>in vitro</em> effects of berberine (BER), a natural alkaloid with numerous biological properties on bovine spermatozoa during three time periods (0 h, 2 h, 24 h). Bovine semen samples were diluted and cultivated in physiological saline solution containing 0.5% DMSO together with 200, 100, 50, 10, 5, and 1 μmol/L BER. Spermatozoa motility was assessed using the computer assisted semen analyzer. The viability of spermatozoa was assessed by the metabolic (MTT) assay, production of superoxide radicals was quantified using the nitroblue tetrazolium (NBT) test, and chemiluminescence was used to evaluate the generation of reactive oxygen species (ROS). Cell lysates were prepared and the extent of lipid peroxidation (LPO) was evaluated using the TBARS assay. The results of the movement activity showed a significant increase in the motility during long term cultivation in case of concentrations ranging between 1 and 10 μmol/L BER (P < 0.01; P < 0.001; 24 h). At the same time, supplementation of 1, 5 and 10 μmol/L BER led to a significant preservation of the cell viability (P < 0.001; 24 h). BER addition at a range of 1-50 μmol/L also provided a significantly higher protection against superoxide (P < 0.05) and ROS (P < 0.001; P < 0.01) overgeneration as well as LPO (P < 0.01; P<0.05) after a 24 h cultivation. We may suggest that supplementation of BER to bovine spermatozoa, particularly at concentrations ranging between 1 and 50 μmol/L, may offer protection to the motility, viability and oxidative status of the spermatozoa, particularly notable at 24 h. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=berberine" title="berberine">berberine</a>, <a href="https://publications.waset.org/abstracts/search?q=bulls" title=" bulls"> bulls</a>, <a href="https://publications.waset.org/abstracts/search?q=motility" title=" motility"> motility</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20profile" title=" oxidative profile"> oxidative profile</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a>, <a href="https://publications.waset.org/abstracts/search?q=viability" title=" viability"> viability</a> </p> <a href="https://publications.waset.org/abstracts/108980/in-vitro-effects-of-berberine-on-the-vitality-and-oxidative-profile-of-bovine-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">831</span> Study on the Spatial Vitality of Waterfront Rail Transit Station Area: A Case Study of Main Urban Area in Chongqing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lianxue%20Shi">Lianxue Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban waterfront rail transit stations exert a dual impact on both the waterfront and the transit station, resulting in a concentration of development elements in the surrounding space. In order to more effectively develop the space around the station, this study focuses on the perspective of the integration of station, city, and people. Taking Chongqing as an example, based on the Arc GIS platform, it explores the vitality of the site from the three dimensions of crowd activity heat, space facilities heat, and spatial accessibility. It conducts a comprehensive evaluation and interpretation of the vitality surrounding the waterfront rail transit station area in Chongqing. The study found that (1) the spatial vitality in the vicinity of waterfront rail transit stations is correlated with the waterfront's functional zoning and the intensity of development. Stations situated in waterfront residential and public spaces are more likely to experience a convergence of people, whereas those located in waterfront industrial areas exhibit lower levels of vitality. (2) Effective transportation accessibility plays a pivotal role in maintaining a steady flow of passengers and facilitating their movement. However, the three-dimensionality of urban space in mountainous regions is a notable challenge, leading to some stations experiencing limited accessibility. This underscores the importance of enhancing the optimization of walking space, particularly the access routes from the station to the waterfront area. (3) The density of spatial facilities around waterfront stations in old urban areas lags behind the population's needs, indicating a need to strengthen the allocation of relevant land and resources in these areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rail%20transit%20station" title="rail transit station">rail transit station</a>, <a href="https://publications.waset.org/abstracts/search?q=waterfront" title=" waterfront"> waterfront</a>, <a href="https://publications.waset.org/abstracts/search?q=influence%20area" title=" influence area"> influence area</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20vitality" title=" spatial vitality"> spatial vitality</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20vitality" title=" urban vitality"> urban vitality</a> </p> <a href="https://publications.waset.org/abstracts/188398/study-on-the-spatial-vitality-of-waterfront-rail-transit-station-area-a-case-study-of-main-urban-area-in-chongqing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">31</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">830</span> Bedouin Dialects: Language Use and Identity Perceptions of Bedouin-Speaking University Students in North-Western Saudi Arabia and Implications for Language Vitality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hend%20Albalawi">Hend Albalawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amid the dynamic use of the Arabic language worldwide, Saudi Arabia employs Modern Standard Arabic (MSA) as its formal, official language, whereas other dialects of Arabic are common in informal situations. Such trends not only maintain the powerful, state-supported status of MSA but are liable to also affect the use and status of other varieties, including Bedouin dialects, and prompt code-mixing behaviour among their speakers. Exposure to MSA and English in education in Saudi Arabia may also be liable to reduce the vitality of Bedouin dialects in the country, particularly among current generations of educated Bedouin speakers. Therefore, the proposed research will involve examining the perceived vitality of Bedouin dialects in Saudi language policies prescribing MSA as the official national language of Saudi Arabia and requiring university students to complete English-language coursework in the national education system. It will also entail identifying Bedouin speakers’ attitudes towards the use of Bedouin dialects in order to assess the need, if any, to implement policies in Saudi Arabia that can enhance the use of those dialects amid the competing use of MSA and English in the country. Empirical data collected from questionnaires and semi-structured interviews that purport patterns of the everyday use of languages among Bedouin-speaking university students in Tabuk, as well as the content of language policy documents, can clarify whether policy-based pressure to use MSA and English in mainstream educational and social activities in Saudi Arabia has jeopardised the language vitality of Bedouin dialects in north-west Saudi Arabia. The findings of the research can thus ultimately contribute to the development of policies to support and enhance the use of Bedouin dialects and, in turn, their language vitality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitudes" title="attitudes">attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=Bedouin%20dialects" title=" Bedouin dialects"> Bedouin dialects</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20policy" title=" language policy"> language policy</a>, <a href="https://publications.waset.org/abstracts/search?q=vitality" title=" vitality"> vitality</a> </p> <a href="https://publications.waset.org/abstracts/124197/bedouin-dialects-language-use-and-identity-perceptions-of-bedouin-speaking-university-students-in-north-western-saudi-arabia-and-implications-for-language-vitality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124197.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">829</span> Effects of Umbilical Cord Clamping on Puppies Neonatal Vitality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20L.%20G.%20Louren%C3%A7o">Maria L.

In human neonates, when the umbilical cord is kept intact after birth, blood continues to flow from the cord to the newborn, but this procedure may prove to be difficult in dogs due to the shorter umbilical cord and the number of newborns in the litter. However, a possible detachment of the placenta while keeping the umbilical cord intact may make the residual blood to flow to the neonate. This study compared the effects on neonatal vitality between clamping and no clamping the umbilical cord of dogs born through cesarean section, assessing them through Apgar and reflex scores. Fifty puppies delivered from 16 bitches were randomly allocated to receive clamping of the umbilical cord immediately (n=25) or to not receive the clamping until breathing (n=25). The neonates were assessed during the first five min of life and once again 10 min after the first assessment. The differences observed between the two moments were significant (p < 0.01) for both the Apgar and reflex scores. The differences observed between the groups (clamped vs. not clamped) were not significant for the Apgar score in the 1st moment (p=0.1), but the 2nd moment was significantly (p < 0.01) in the group not clamped, as well as significant (p < 0.05) for the reflex score in the 1st moment and 2nd moment (p < 0.05), revealing higher neonatal vitality in the not clamped group. The differences observed between the moments (1st vs. 2nd) of each group as significant (p < 0.01), revealing higher neonatal vitality in the 2nd moments. In the no clamping group, after removing the neonates together with the umbilical cord and the placenta, we observed that the umbilical cords were full of blood at the time of birth and later became whitish and collapsed, demonstrating the blood transfer. The results suggest that keeping the umbilical cord intact for at least three minutes after the onset breathing is not detrimental and may contribute to increase neonate vitality in puppies delivered by cesarean section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=puppy%20vitality" title="puppy vitality">puppy vitality</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn%20dog" title=" newborn dog"> newborn dog</a>, <a href="https://publications.waset.org/abstracts/search?q=cesarean%20section" title=" cesarean section"> cesarean section</a>, <a href="https://publications.waset.org/abstracts/search?q=Apgar%20score" title=" Apgar score"> Apgar score</a> </p> <a href="https://publications.waset.org/abstracts/117726/effects-of-umbilical-cord-clamping-on-puppies-neonatal-vitality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117726.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">828</span> Challenges in Self-Managing Vitality: A Qualitative Study about Staying Vital at Work among Dutch Office Workers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Violet%20Petit-Steeghs">Violet Petit-Steeghs</a>, <a href="https://publications.waset.org/abstracts/search?q=Jochem%20J.%20R.%20Van%20Roon"> Jochem J.

Broerse </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Last decennia the retirement age in Europe is gradually increasing. As a result, people have to continue working for a longer period of time. Health problems due to increased sedentary behavior and mental conditions like burn-out, pose a threat in fulfilling employees’ working life. In order to stimulate the ability and willingness to work in the present and future, it is important to stay vital. Vitality is regarded in literature as a sense of energy, motivation and resilience. It is assumed that by increasing their vitality, employees will stay healthier and be more satisfied with their job, leading to a more sustainable employment and less absenteeism in the future. The aim of this project is to obtain insights into the experiences and barriers of employees, and specifically office workers, with regard to their vitality. These insights are essential in order to develop appropriate measures in the future. To get more insights in the experiences of office workers on their vitality, 8 focus group discussions were organized with 6-10 office workers from 4 different employers (an university, a national construction company and a large juridical and care service organization) in the Netherlands. The discussions were transcribed and analyzed via open coding. This project is part of a larger consortium project Provita2, and conducted in collaboration with University of Technology Eindhoven. Results showed that a range of interdependent factors form a complex network that influences office workers’ vitality. These factors can be divided in three overarching groups: (1) personal (2) organizational and (3) environmental factors. Personal intrinsic factors, relating to the office worker, comprise someone’s physical health, coping style, life style, needs, and private life. Organizational factors, relating to the employer, are the workload, management style and the structure, vision and culture of the organization. Lastly, environmental factors consist of the air, light, temperature at the workplace and whether the workplace is inspiring and workable. Office workers experienced barriers to improve their own vitality due to a lack of autonomy. On the one hand, because most factors were not only intrinsic but extrinsic, like work atmosphere or the temperature in the room. On the other hand, office workers were restricted in adapting both intrinsic as well as extrinsic factors. Restrictions to for instance the flexibility of working times and the workload, can set limitations for improving vitality through personal factors like physical activity and mental relaxation. In conclusion, a large range of interdependent factors influence the vitality of office workers. Office workers are often regarded to have a responsibility to improve their vitality, but are limitedly autonomous in adapting these factors. Measures to improve vitality should therefore not only focus on increasing awareness among office workers, but also on empowering them to fulfill this responsibility. A holistic approach that takes the complex mutual dependencies between the different factors and actors (like managers, employees and HR personnel) into account is highly recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title="occupational health">occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=perspectives%20office%20workers" title=" perspectives office workers"> perspectives office workers</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20employment" title=" sustainable employment"> sustainable employment</a>, <a href="https://publications.waset.org/abstracts/search?q=vitality%20at%20work" title=" vitality at work"> vitality at work</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20%26%20wellbeing" title=" work & wellbeing"> work & wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/84768/challenges-in-self-managing-vitality-a-qualitative-study-about-staying-vital-at-work-among-dutch-office-workers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84768.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">827</span> Nonlinear Evolution on Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benniche%20Omar">Benniche Omar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We are concerned with abstract fully nonlinear differential equations having the form y’(t)=Ay(t)+f(t,y(t)) where A is an m—dissipative operator (possibly multi—valued) defined on a subset D(A) of a Banach space X with values in X and f is a given function defined on I×X with values in X. We consider a graph K in I×X. We recall that K is said to be viable with respect to the above abstract differential equation if for each initial data in K there exists at least one trajectory starting from that initial data and remaining in K at least for a short time. The viability problem has been studied by many authors by using various techniques and frames. If K is closed, it is shown that a tangency condition, which is mainly linked to the dynamic, is crucial for viability. In the case when X is infinite dimensional, compactness and convexity assumptions are needed. In this paper, we are concerned with the notion of near viability for a given graph K with respect to y’(t)=Ay(t)+f(t,y(t)). Roughly speaking, the graph K is said to be near viable with respect to y’(t)=Ay(t)+f(t,y(t)), if for each initial data in K there exists at least one trajectory remaining arbitrary close to K at least for short time. It is interesting to note that the near viability is equivalent to an appropriate tangency condition under mild assumptions on the dynamic. Adding natural convexity and compactness assumptions on the dynamic, we may recover the (exact) viability. Here we investigate near viability for a graph K in I×X with respect to y’(t)=Ay(t)+f(t,y(t)) where A and f are as above. We emphasis that the t—dependence on the perturbation f leads us to introduce a new tangency concept. In the base of a tangency conditions expressed in terms of that tangency concept, we formulate criteria for K to be near viable with respect to y’(t)=Ay(t)+f(t,y(t)). As application, an abstract null—controllability theorem is given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abstract%20differential%20equation" title="abstract differential equation">abstract differential equation</a>, <a href="https://publications.waset.org/abstracts/search?q=graph" title=" graph"> graph</a>, <a href="https://publications.waset.org/abstracts/search?q=tangency%20condition" title=" tangency condition"> tangency condition</a>, <a href="https://publications.waset.org/abstracts/search?q=viability" title=" viability"> viability</a> </p> <a href="https://publications.waset.org/abstracts/93317/nonlinear-evolution-on-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93317.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">826</span> Sustainability of Environment and Green Energy Strategies Comprehensive Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Pirooznia">Vahid Pirooznia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this think about we propose a few green vitality procedures for feasible advancement.

About the half of world population is living in cities, and the urban environment is negatively affecting the mental health of modern people. The stress level of urban dwellers continues to increase, and they pursue nature-based recreation activities to relieve their stresses. It was found that activities in green spaces are improving concentration, relieving mental stress, and positively affecting physical activities and social relationship, thus enhancing the quality of life. For that reason, studies have been continuously conducted on the role of nature, which is a green space for pursuing health and relieving the stress of urban dwellers. Therefore, this study investigated the effect of experiencing a restoration from nature-based outdoor recreation activities of urban dwellers on their quality of life for the groups with high and low-stress levels. The results of the analysis against visitors who trekked and climbed Mt. Bukhan National Park in Seoul, South Korea showed that the effect of perceiving restorative environment on relaxation, calmness and subjective vitality, and the effect of relaxation and calmness on the quality of life were similar in both groups. However, it was found that subjective vitality affected the quality of life in the group with the high-stress group, while it did not show a significant result in the low-stress group. This is because the high-stress group increased their belief in the future and themselves and vitality through nature-based outdoor activities, which in turn affected their quality of life, while people in the low-stress group normally have subjective vitality in their daily lives, not affected by nature-based outdoor recreation. This result suggests that urban dwellers feel relaxed and calm through nature-based outdoor recreation activities with perceived restorative environment, and such activities enhance their quality of life. Therefore, a wellbeing policy is needed to enhance the quality of life of citizens by creating green spaces in city centers for the promotion of public health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healing%20tourism" title="healing tourism">healing tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=nature-based%20outdoor%20recreation" title=" nature-based outdoor recreation"> nature-based outdoor recreation</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20restorative%20environment" title=" perceived restorative environment"> perceived restorative environment</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/41507/an-analysis-of-structural-relationship-among-perceived-restorative-environment-relaxing-experience-subjective-vitality-and-the-health-related-quality-of-life-of-the-participants-in-nature-based-urban-outdoor-recreation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">823</span> Effect of Capsule Storage on Viability of Lactobacillus bulgaricus and Streptococcus thermophilus in Yogurt Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanchana%20Sitlaothaworn">Kanchana Sitlaothaworn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Yogurt capsule was made by mixing 14% w/v of reconstitution of skim milk with 2% FOS.

The vast malignant gliomas are not curable despite the therapy (surgical, radiotherapy, chemotherapy) and patients seek alternative or complementary treatments. Patients often use cannabidiol (CBD) oil as an alternative therapy of glioblastoma. CBD is one of the cannabinoids, an active component of Cannabis sativa. THC (Δ9-tetrahydrocannabinol) can be addictive, and in many countries CBD oil without THC ( < 0,2%) is available. Propolis produced by bees from the resin collected from trees has antiglioma properties in vitro and can be used as a supplement in complementary therapy of gliomas. The aim of this study was to examine the influence of extract from CBD oil in combination with propolis extract on two glioblastoma cell lines. The MTT (Thiazolyl Blue Tetrazolium Bromide) test was used to determine the influence of CBD oil extract and polish propolis extract (PPE) on the viability of glioblastoma cell lines – U87MG and LN18. The cells were incubated (24, 48 and 72 h) with CBD oil extract and PPE. CBD extract was used in concentration 1, 1.5 and 3 µM and PPE in 30 µg/mL. The data were presented compared to the control. The statistical analysis was performed using Statistica v. 13.0 software. CBD oil extract in concentrations 1, 1.5 and 3 µM did not inhibit the viability of U87MG and LN18 cells (viability more than 90% cells compared to the control). There was no dose-response viability, and IC50 value was not recognized. PPE in the concentration of 30 µg/mL time-dependently inhibited the viability of U87MG and LN18 cell line (after 48 h the viability as a percent of the control was 59,7±6% and 57,8±7%, respectively). In a combination of CBD with PPE, the viability of the treated cells was similar to PPE used alone (58,2±7% and 56,5±9%, respectively). CBD oil extract did not show anti-glioma activity and in combination with PPE did not change the activity of PPE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cannabidiol" title=" cannabidiol"> cannabidiol</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20line" title=" cell line"> cell line</a>, <a href="https://publications.waset.org/abstracts/search?q=glioblastoma" title=" glioblastoma"> glioblastoma</a> </p> <a href="https://publications.waset.org/abstracts/104232/the-activity-of-polish-propolis-and-cannabidiol-oil-extracts-on-glioblastoma-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">820</span> In vitro Effects of Amygdalin on the Functional Competence of Rabbit Spermatozoa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marek%20Halen%C3%A1r">Marek Halenár</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1"> Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%C3%A1%C5%A1%20Slanina"> Tomáš Slanina</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%BDubom%C3%ADr%20Ondru%C5%A1ka"> Ľubomír Ondruška</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduard%20Koles%C3%A1r"> Eduard Kolesár</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Mass%C3%A1nyi"> Peter Massányi</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Koles%C3%A1rov%C3%A1"> Adriana Kolesárová </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present <em>in vitro</em> study was designed to reveal whether amygdalin (AMG) is able to cause changes to the motility, viability and mitochondrial activity of rabbit spermatozoa. New Zealand White rabbits (n = 10) aged four months were used in the study. Semen samples were collected from each animal and used for the <em>in vitro </em>incubation. The samples were divided into five equal parts and diluted with saline supplemented with 0, 0.5, 1, 2.5 and 5 mg/mL AMG. At times 0h, 3h and 5h spermatozoa motion parameters were assessed using the SpermVision™ computer-aided sperm analysis (CASA) system, cell viability was examined with the metabolic activity (MTT) assay, and the eosin-nigrosin staining technique was used to evaluate the viability of rabbit spermatozoa. All AMG concentrations exhibited stimulating effects on the spermatozoa activity, as shown by a significant preservation of the motility (P<0.05 with respect to 0.5 mg/mL and 1 mg/mL AMG; Time 5 h) and mitochondrial activity (P< 0.05 in case of 0.5 mg/mL AMG; P< 0.01 in case of 1 mg/mL AMG; P < 0.001 with respect to 2.5 mg/mL and 5 mg/mL AMG; Time 5 h). None of the AMG doses supplemented had any significant impact of the spermatozoa viability. In conclusion, the data revealed that short-term co-incubation of spermatozoa with AMG may result in a higher preservation of the sperm structural integrity and functional activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amygdalin" title="amygdalin">amygdalin</a>, <a href="https://publications.waset.org/abstracts/search?q=CASA" title=" CASA"> CASA</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20activity" title=" mitochondrial activity"> mitochondrial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=motility" title=" motility"> motility</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbits" title=" rabbits"> rabbits</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a>, <a href="https://publications.waset.org/abstracts/search?q=viability" title=" viability"> viability</a> </p> <a href="https://publications.waset.org/abstracts/55018/in-vitro-effects-of-amygdalin-on-the-functional-competence-of-rabbit-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55018.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">819</span> Inductions of CaC₂ on Sperm Morphology and Viability of the Albino Mice (Mus musculus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dike%20H.%20Ogbuagu">Dike H.

Thirty isogenic strains of male albino mice, Mus musculus (age≈ 8weeks; weight= 32.5±2.0g) were acclimatized (ambient temperature 28.0±1.0°C) for 2 weeks and fed standard growers mash and water ad libutum. They were later exposed to graded toxicant concentrations (w/w) of 2.5000, 1.2500, 0.6250, and 0.3125% in 4 cages. A control cage was also established. After 5 weeks, 3 animals from each cage were sacrificed by cervical dislocation and the cauda epididymis excised. Sperm morphology and viability were determined by microscopic procedures. The ANOVA, means plots, Student’s t-test and variation plots were used to analyze data. The common abnormalities observed included Double Head, Pin Head, Knobbed Head, No Tail and With Hook. The higher toxicant concentrations induced significantly lower body weights [F(829.899) ˃ Fcrit(4.19)] and more abnormalities [F(26.52) ˃ Fcrit(4.00)] at P˂0.05.

In this study, typical W/O and O/W emulsions with and without oil gelation were used to encapsulate L. plantarum. The effects of emulsion types on the viability of L. plantarum during storage and GI tract were investigated. Besides, the position of L. plantarum in emulsion system and its number of viable cells when threating by adverse environment was correlated in order to figure out which type of emulsion is more suitable as food carrier for probiotics encapsulation and protection. As a result, probiotics tend to migrate from oil to water phase due to the natural hydrophilicity; however, it’s harmful for cells viability when surrounding by water for a long time. Oil gelation in emulsions is one of the promising strategies for inhibiting the cells mobility and decreasing the contact with adverse factors (e.g., water, exogenous enzymes and gastric acid), thus enhancing the number of viable cells that enough to exert its beneficial effects in host. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emulsion" title="emulsion">emulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=gelation" title=" gelation"> gelation</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a> </p> <a href="https://publications.waset.org/abstracts/165145/typical-emulsions-as-probiotic-food-carrier-effect-of-cells-position-on-its-viability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165145.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">817</span> Study of Influencing Factors of Shrinking Cities Based on Factor Analysis: The Example of Halle Germany</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fang%20Yao">Fang Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Minglei%20Chen"> Minglei Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> City shrinkage is one of the thorny problems that many European cities have to face with nowadays. It is mainly expressed as the decrease of population in these cities. Eastern Germany is one of the pioneers of European shrinking cities with long shrinking history. Selecting one representative shrinking city Halle(Saale) in eastern Germany as research objective, collecting and investigating nearly 20 years (1993-2010) municipal data after the reunification of Germany. These data based on five dimensions, which are demographic, economic, social, spatial and environmental and total 16 eligible variables. Using Factor Analysis to dealing with these variables in order to assess the most important factors affecting shrinking Halle. The Factor Analysis shows that there are three main factors determine the shrinkage of Halle, namely demographical and economical factor, social stability factor, and city vitality factor. Three factors acts at different period of Halle’s shrinkage: from 1993 to 1997 the demographical and economical factor played an important role; from 1997 to 2004 the social stability is significant to city shrinkage; since 2005 city vitality factors determines the shrinkage of Halle. In recent years, the shrinkage in Halle mitigates that shows the sign of growing population. Thus the city Halle should focus on attaching more importance on the city vitality factor to prevent the city from shrinkage. Meanwhile, the city should possess a positive perspective that to shift the growth-oriented development to tap the potential of shrinking cities. This method is expected to apply to further research and other shrinking cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demography" title="demography">demography</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20analysis" title=" factor analysis"> factor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Halle" title=" Halle"> Halle</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinking%20cities" title=" shrinking cities"> shrinking cities</a> </p> <a href="https://publications.waset.org/abstracts/17187/study-of-influencing-factors-of-shrinking-cities-based-on-factor-analysis-the-example-of-halle-germany" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">816</span> Comparative Evaluation of Different Extenders and Sperm Protectors to Keep the Spermatozoa Viable for More than 24 Hours</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Raseona">A.

This study evaluated the effectiveness of different extenders to preserve Nguni bull semen stored at controlled room temperature 24 °C for three days, as an alternative to frozen-thawed semen straws used for artificial insemination. Semen samples were collected from two Nguni bulls using an electro-ejaculator and transported to the laboratory for evaluation. Pooled semen was aliquot into three extenders Triladyl, Ham’s F10 and M199 at a dilution ratio of 1:4 then stored at controlled room temperature 24 °C. Sperm motility was analysed after 0, 24, 48 and 72 hours. Morphology and viability were analysed after 72 hours. The study was replicated four times and data was analysed by analysis of variance (ANOVA). Triladyl showed higher viability percentage and consistent total motility for three days. Ham’s F10 showed higher progressive motility compared to the other extenders. There was no significant difference in viability between Ham’s F10 and M199. No significant difference was also observed in total abnormality between the two Nguni bulls. In conclusion, Nguni semen can be preserved in Triladyl or Ham’s F10 and M199 culture media stored at 24 °C and stay alive for three days. Triladyl proved to be the best extender showing high viability and consistency in total motility as compared to Ham’s F10 and M199. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bull%20semen" title="bull semen">bull semen</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20insemination" title=" artificial insemination"> artificial insemination</a>, <a href="https://publications.waset.org/abstracts/search?q=Triladyl" title=" Triladyl"> Triladyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Ham%E2%80%99s%20F10" title=" Ham’s F10"> Ham’s F10</a>, <a href="https://publications.waset.org/abstracts/search?q=M199" title=" M199"> M199</a>, <a href="https://publications.waset.org/abstracts/search?q=viability" title=" viability"> viability</a> </p> <a href="https://publications.waset.org/abstracts/28623/comparative-evaluation-of-different-extenders-and-sperm-protectors-to-keep-the-spermatozoa-viable-for-more-than-24-hours" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28623.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">500</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">815</span> Research on Energy Field Intervening in Lost Space Renewal Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tianyue%20Wan">Tianyue Wan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lost space is the space that has not been used for a long time and is in decline, proposed by Roger Trancik. And in his book Finding Lost Space: Theories of Urban Design, the concept of lost space is defined as those anti-traditional spaces that are unpleasant, need to be redesigned, and have no benefit to the environment and users. They have no defined boundaries and do not connect the various landscape elements in a coherent way. With the rapid development of urbanization in China, the blind areas of urban renewal have become a chaotic lost space that is incompatible with the rapid development of urbanization. Therefore, lost space needs to be reconstructed urgently under the background of infill development and reduction planning in China. The formation of lost space is also an invisible division of social hierarchy. This paper tries to break down the social class division and the estrangement between people through the regeneration of lost space. Ultimately, it will enhance vitality, rebuild a sense of belonging, and create a continuous open public space for local people. Based on the concept of lost space and energy field, this paper clarifies the significance of the energy field in the lost space renovation. Then it introduces the energy field into lost space by using the magnetic field in physics as a prototype. The construction of the energy field is support by space theory, spatial morphology analysis theory, public communication theory, urban diversity theory and city image theory. Taking Wuhan’s Lingjiao Park of China as an example, this paper chooses the lost space on the west side of the park as the research object. According to the current situation of this site, the energy intervention strategies are proposed from four aspects: natural ecology, space rights, intangible cultural heritage and infrastructure configuration. And six specific lost space renewal methods are used in this work, including “riveting”, “breakthrough”, “radiation”, “inheritance”, “connection” and “intersection”. After the renovation, space will be re-introduced into the active crow. The integration of activities and space creates a sense of place, improve the walking experience, restores the vitality of the space, and provides a reference for the reconstruction of lost space in the city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20vitality%20intervention" title="dynamic vitality intervention">dynamic vitality intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=lost%20space" title=" lost space"> lost space</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20vitality" title=" space vitality"> space vitality</a>, <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20place" title=" sense of place"> sense of place</a> </p> <a href="https://publications.waset.org/abstracts/117317/research-on-energy-field-intervening-in-lost-space-renewal-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117317.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">814</span> Design of 3D Bioprinted Scaffolds for Cartilage Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Pinilla">Gloria Pinilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Manuel%20Baena"> Jose Manuel Baena</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20%20G%C3%A1lvez-Mart%C3%ADn"> Patricia Gálvez-Martín</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Antonio%20Marchad"> Juan Antonio Marchad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cartilage is a dense connective tissue with limited self-repair properties. Currently, the therapeutic use of autologous or allogenic chondrocytes makes up an alternative therapy to the pharmacological treatment. The design of a bioprinted 3D cartilage with chondrocytes and biodegradable biomaterials offers a new therapeutic alternative able of bridging the limitations of current therapies in the field. We have developed an enhanced printing processes-Injection Volume Filling (IVF) to increase the viability and survival of the cells when working with high-temperature thermoplastics without the limitation of the scaffold geometry in contact with cells. We have demonstrated the viability of the printing process using chondrocytes for cartilage regeneration. This development will accelerate the clinical uptake of the technology and overcomes the current limitation when using thermoplastics as scaffolds. An alginate-based hydrogel combined with human chondrocytes (isolated from osteoarthritis patients) was formulated as bioink-A and the polylactic acid as bioink-B. The bioprinting process was carried out with the REGEMAT V1 bioprinter (Regemat 3D, Granada-Spain) through a IVF. The printing capacity of the bioprinting plus the viability and cell proliferation of bioprinted chondrociytes was evaluated after five weeks by confocal microscopy and Alamar Blue Assay (Biorad). Results showed that the IVF process does not decrease the cell viability of the chondrocytes during the printing process as the cells do not have contact with the thermoplastic at elevated temperatures. The viability and cellular proliferation of the bioprinted artificial 3D cartilage increased after 5 weeks. In conclusion, this study demonstrates the potential use of Regemat V1 for 3D bioprinting of cartilage and the viability of bioprinted chondrocytes in the scaffolds for application in regenerative medicine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cartilage%20regeneration" title="cartilage regeneration">cartilage regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=bioprinting" title=" bioprinting"> bioprinting</a>, <a href="https://publications.waset.org/abstracts/search?q=bioink" title=" bioink"> bioink</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title=" scaffold"> scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=chondrocyte" title=" chondrocyte"> chondrocyte</a> </p> <a href="https://publications.waset.org/abstracts/71676/design-of-3d-bioprinted-scaffolds-for-cartilage-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">813</span> In vitro Study on Characterization and Viability of Vero Cell Lines after Supplementation with Porcine Follicular Fluid Proteins in Culture Medium </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayuva%20Youngsabanant">Mayuva Youngsabanant</a>, <a href="https://publications.waset.org/abstracts/search?q=Suphaphorn%20Rabiab"> Suphaphorn Rabiab</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatairuk%20Tungkasen"> Hatairuk Tungkasen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nongnuch%20Gumlungpat"> Nongnuch Gumlungpat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayuree%20Pumipaiboon"> Mayuree Pumipaiboon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The porcine follicular fluid proteins (pFF) of healthy small size ovarian follicles (1-3 mm in diameters) of Large White pig ovaries were collected by sterile technique. They were used for testing the effect on cell viability and characterization of Vero cell lines using MTT assay. Two hundred microliter of round shape Vero cell lines were culture in 96 well plates with DMEM for 24 h. After that, they were attachment to substrate and some changed into fibroblast shape and spread over the surface after culture for 48 h. Then, Vero cell lines were treated with pFF at concentration of 2, 4, 20, 40, 200, 400, 500, and 600 µg proteins/mL for 24 h. Yields of the best results were analyzed by using one-way ANOVA. MTT assay reviewed an increasing in percentage of viability of Vero cell lines indicated that at concentration of 400-600 µg proteins/mL showed higher percentage of viability (115.64 ± 6.95, 106.91 ± 5.27 and 116.73 ± 20.15) than control group. They were significantly different from the control group (p < 0.05) but lower than the positive control group (DMEM with 10% heat treated fetal bovine serum). Cell lines showed normal character in fibroblast elongate shape after treated with pFF except in high concentration of pFF. This result implies that pFF of small size ovarian follicle at concentration of 400-600 µg proteins/mL could be optimized concentration for using as a supplement in Vero cell line culture medium to promote cell viability instead of growth hormone from fetal bovine serum. This merit could be applied in other cell biotechnology researches.

For this, the testicles of 100 bulls slaughtered on Terceira Island were dissected, the epididymal tails were separated, and semen was recovered by the flotation method and then evaluated by phase contrast microscopy and by flow cytometry. For phase contrast microscopy, a drop of semen was used to evaluate the percentage of motile spermatozoa (from 0 to 100%) and motility (from 0 to 5). After determining the concentration and the abnormal forms, semen was diluted to a final concentration of 50 x 106 spz/ml and evaluated by flow cytometer for membrane and acrosome integrity using the conjugation of fluorescent probes propidium iodide (PI) and Arachis hypogea agglutinin (FITC-PNA). Freezing was carried out in a programmable semen freezer, using 0.25 ml straws, in a total of 20 x 106 viable sperm per straw with glycerol as a cryoprotectant in a final concentration of 0.58 M. It was observed that, on average, a total of 7.25 ml of semen was collected from each bull. The viability and vitality rates were respectively 83.22 ± 7.52% and 3.8 ± 0.4 before freezing, decreasing to 58.81 ± 11.99% and 3.6 ± 0.6, respectively, after thawing. Regarding cytoplasmic droplets, it was observed that a high percentage of spermatozoa had medial cytoplasmic droplets (38.47%), with only 3.32% and 0.15% presenting proximal and distal cytoplasmic drops, respectively. By flow cytometry, it was observed that before freezing, the percentage of sperm with the damaged plasma membrane and intact acrosome was 3.61 ± 0.99%, increasing slightly to 4.21 ± 1.86% after cryopreservation (p<0.05). Regarding spermatozoa with damaged plasma membrane and acrosome, the percentage before freezing was 3.37±1.87%, increasing to 4.34 ±1.16% after thawing, and no significant differences were observed between these two values. For the percentage of sperm with the intact plasma membrane and damaged acrosome, this value was 2.04 ± 2.34% before freezing, decreasing to 0.89 ± 0.48% after thawing (p<0.05). The percentage of sperm with the intact plasma membrane and acrosome before freezing was 90.99±2.75%, with a slight decrease to 90.57±3.15% after thawing (p<0.05). From this study, it can be clearly concluded that, after the slaughtering of bulls, the spermatozoa can be recovered from the epididymis and cryopreserved, maintaining an excellent rate of sperm viability and quality after thawing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20semen" title="bovine semen">bovine semen</a>, <a href="https://publications.waset.org/abstracts/search?q=epididymis" title=" epididymis"> epididymis</a>, <a href="https://publications.waset.org/abstracts/search?q=cryopreservation" title=" cryopreservation"> cryopreservation</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility%20assessment" title=" fertility assessment"> fertility assessment</a> </p> <a href="https://publications.waset.org/abstracts/158029/collection-cryopreservation-and-fertilizing-potential-of-bovine-spermatozoa-collected-from-the-epididymis-evaluated-by-conventional-techniques-and-by-flow-cytometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">811</span> Sociolinguistics and Language Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Banazzouz%20Halima">Banazzouz Halima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Throughout the ages, language has been viewed not only as a simple code of communicating information but rather as the most powerful and versatile medium of maintaining relationships with other people. While,by the end of the 18th century, such matters of scientific investigation concerning the study of human language began to occur under the scope of “Linguistics” generally defined as the scientific study of language. Linguistics, thus, provides a growing body of scientific knowledge about language which can guide the activity of the language teacher and student as well. Moreover,as times passed, the linguistic development engaged language in a broadly practiced academic discipline having relationship with other sciences such as: psychology, sociology, anthropology etc. Therefore, “Sociolinguistics” was given birth during the 1960’s. In fact, the given abstract is mainly linguistic, inserted under the scope of “Sociolinguistics” and by far it highlights on the process of linguistic variation and language change to show that all languages change through time and linguistic systems may vary from one speech community to another providing there is a sense of vitality where people of different parts of the globe may mutually and intelligibly communicate and comprehend each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language%20change-sociolinguistics" title="language change-sociolinguistics">language change-sociolinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20context-speech%20community" title=" social context-speech community"> social context-speech community</a>, <a href="https://publications.waset.org/abstracts/search?q=vitality%20of%20language" title=" vitality of language"> vitality of language</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20variation" title=" linguistic variation"> linguistic variation</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20dialectology" title=" urban dialectology"> urban dialectology</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20dialectology" title=" urban dialectology"> urban dialectology</a> </p> <a href="https://publications.waset.org/abstracts/15717/sociolinguistics-and-language-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15717.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">628</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">810</span> Safety Assessment and Prophylactic Efficacy of Moringa stenopetala Leaf Extract Through Mitigation of Oxidative Stress in BV-2 Microglial Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Adeniyi%20Adefegha">Stephen Adeniyi Adefegha</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Mostardeiro"> Vitor Mostardeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Vera%20Maria%20Morsch"> Vera Maria Morsch</a>, <a href="https://publications.waset.org/abstracts/search?q=Ademir%20F.%20Morel"> Ademir F.

Purpose: This study was set up in order to assess the effect of aqueous extract of Moringa stenopetala on cell viability and oxidative stress biomarkers in BV-2 microglial cells. Aqueous extracts of M. stenopetala were prepared, lyophilized and reconstituted in 0.5% dimethylsulphoxide (DMSO). Cells were treated with M. stenopetala extracts (0.1 - 100 µg/ml) for cell viability and nitric oxide (NO) production tests. However, M. stenopetala extract (50 µg/ml) was used in the treatment of cells for the determination of protein carbonyl content and reactive oxygen species (ROS) level. Incubation of BV-2 microglia cell with M. stenopetala extract maintained cell viability, diminished NO and ROS levels, and reduced protein carbonyl contents Chlorogenic acid, rutin, kaempferol and quercetin derivatives were the main phenolic compounds identified in M. stenopetala leaf extract. These phenolic compounds present in M. stenopetala may be responsible for the mitigation of oxidative stress in BV-2 microglial cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title="oxidative stress">oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=BV-2%20microglial%20cell" title=" BV-2 microglial cell"> BV-2 microglial cell</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa%20stenopetala" title=" Moringa stenopetala"> Moringa stenopetala</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20viability" title=" cell viability"> cell viability</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a> </p> <a href="https://publications.waset.org/abstracts/157189/safety-assessment-and-prophylactic-efficacy-of-moringa-stenopetala-leaf-extract-through-mitigation-of-oxidative-stress-in-bv-2-microglial-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">809</span> Land Layout and Urban Design of New Cities in Underdeveloped Areas of China: A Case Study of Xixian New Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Libin%20Ouyang">Libin Ouyang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China has experienced a very fast urbanization process in the past two decades. Due to the uncoordinated characteristics of regional development in China, a large number of people from rural areas or small towns have flooded into regional central cities, which are building new cities around them due to the shortage of construction land or the need for urban development. However, the construction of some new cities has not achieved the expected effect, the absorption capacity of industry and population is limited, and the phenomenon of capital and land waste is obvious. This paper takes the Xixian New Area in Shaanxi Province, an inland region in Northwest China, as an example, and tries to analyse the reasons for the lack of vitality in the current situation of the Xixian New Area from the perspective of site layout and urban design, analyses the practical experience of the construction of new city cores in developed countries and regions, and studies how to optimise at the level of site layout planning and urban design to improve the vitality and attractiveness of the new city, decongest the population of large cities, effectively solve the problems of large cities, and promote The study will also examine how to optimise land use planning and urban design to enhance the vitality and attractiveness of new cities, relieve the population of large cities, effectively solve the problems of large cities and promote sustainable development of new cities. The study can serve as a reference for urban planners and policy makers, provide theoretical assistance for new city construction in other less developed regions of China, and provide some case references for urban construction in other developing countries undergoing rapid urbanisation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20city" title="new city">new city</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20layout" title=" land use layout"> land use layout</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20design" title=" urban design"> urban design</a>, <a href="https://publications.waset.org/abstracts/search?q=attraction" title=" attraction"> attraction</a> </p> <a href="https://publications.waset.org/abstracts/165771/land-layout-and-urban-design-of-new-cities-in-underdeveloped-areas-of-china-a-case-study-of-xixian-new-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">808</span> Effects of Pre-Storage Invigoration Treatments on Ageing Dendrocalamus hamiltonii Seeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geetika%20Richa">Geetika Richa</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20L.%20Sharma"> M.

Modern analysis of bamboos show high amount of vitamins and minerals which makes them valuable as a curative. Bamboo leaf decoction and young shoots are known as remedy for intestinal worms, healing of ulcers and stomach disorders. Bamboos are known to be propagated by large scale plantations but propagation through seeds occurs very limited as they have very short viability of few months. Seeds loses viability over a period of time even under controlled conditions and important factors that affect seed viability is the decline in reserve food material, decrease in membrane integrity and fall in endogenous level of growth hormones. Invigoration treatments that include hydration, dehydration, incorporation of bioactive chemicals such as growth regulators, nutrients and antioxidants etc. improve the seed performance. Our studies were aimed to determine the most effective invigoration treatments to enhance vigour and viability of seeds by following invigoration treatments, i.e., hardening. Treated seeds were stored at controlled temperature and humidity (in desiccators at 4°C). In hardening, chemicals were applied in 3 different concentrations to three replicates of 10 seeds. Hardening was done withGA3, IAA, (each with concentrations of 10 ppm, 20 ppm and 50 ppm), calcium oxychloride, neem leaf powder and clay (each with concentrations of 2%, 5% and 10%). Statistically all the hardening materials were effective but GA3 50 ppm was the most effective one in maintaining germination percentage and vigour index. Hardening treatments increased the germination percentage of seeds, i.e. 86.2%, over control which showed germination percentage of 80.2%. It was concluded that in order to maintain seed viability during storage for longer period of time, invigoration treatments have been found to be very effective. <p
