The carbohydrate metabolism in A mellifera has not been understood fully, as there are no data available, on the functional expression of cellulase gene. The cellulose hydrolyzing enzyme is required for the digestion of pollen cellulose wall, to release the important nutrients (amino acids, minerals, vitamins etc.) from the pollen. A dissection of Apis genome had revealed that there is one gene present for the expression of endo-beta-1,4-glucanase, for cellulose hydrolysis. In the presented work, functional expression of endo-beta-1,4 glucanase gene is reported. Total soluble proteins of the honey bee were isolated and were tested cellulose hydrolyzing enzyme activity, using carboxy-methyl cellulose, as a substrate. A mellifera proteins were able to hydrolyze carboxy-methyl cellulose, confirming its endo- type mode of action. Endo beta-1,4 glucanase enzyme was only present in the gut tissues, no activity was detected in the salivary glands. The pH optima of the enzyme were in the acidic pH range of 4-5-5-0, indicating its metabolic role in the acidic stomach of A mellifera. The reported enzyme is unique, as endo-beta- 1,4 glucanase was able to generate non reducing sugar, as an end product. The results presented, are supportive to the information that the honey bee is capable of producing its novel endo-beta-1,4 glucanase. Further it could be helpful, in understanding, the carbohydrate metabolism in A mellifera. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=honey%20bees" title="honey bees">honey bees</a>, <a href="https://publications.waset.org/abstracts/search?q=Endo-beta%201" title=" Endo-beta 1"> Endo-beta 1</a>, <a href="https://publications.waset.org/abstracts/search?q=4-%20glucanase" title="4- glucanase">4- glucanase</a>, <a href="https://publications.waset.org/abstracts/search?q=Apis%20mellifera" title=" Apis mellifera"> Apis mellifera</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20expression" title=" functional expression"> functional expression</a> </p> <a href="https://publications.waset.org/abstracts/2425/functional-expression-and-characterization-of-a-novel-indigenous-endo-beta-14-glucanase-from-apis-mellifera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2425.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">403</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">135</span> Analyzing the Performance Properties of Stress Absorbing Membrane Interlayer Modified with Recycled Crumb Rubber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Asgharzadeh">Seyed Mohammad Asgharzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Moein%20Biglari"> Moein Biglari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asphalt overlay is the most commonly used technique of pavement rehabilitation. However, the reflective cracks which occur on the overlay surface after a short period of time are the most important distresses threatening the durability of new overlays. Stress Absorbing Membrane Interlayers (SAMIs) are used to postpone the reflective cracking in the overlays. Sand asphalt mixtures, in unmodified or crumb rubber modified (CRM) conditions, can be used as an SAMI material. In this research, the performance properties of different SAMI applications were evaluated in the laboratory using an Indirect Tensile (IDT) fracture energy. The IDT fracture energy of sand asphalt samples was also evaluated and then compared to that of the regular dense graded asphalt used as an overlay. Texas boiling water and modified Lottman tests were also conducted to evaluate the moisture susceptibility of sand asphalt mixtures. The test results showed that sand asphalt mixtures can stand higher levels of energy before cracking, and this is even more pronounced for the CRM sand mix. Sand asphalt mixture using CRM binder was also shown to be more resistance to moisture induced distresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SAMI" title="SAMI">SAMI</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20asphalt" title=" sand asphalt"> sand asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=crumb%20rubber" title=" crumb rubber"> crumb rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20tensile%20test" title=" indirect tensile test"> indirect tensile test</a> </p> <a href="https://publications.waset.org/abstracts/72996/analyzing-the-performance-properties-of-stress-absorbing-membrane-interlayer-modified-with-recycled-crumb-rubber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72996.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">228</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">134</span> Improvement of Fatigue and Fatigue Corrosion Resistances of Turbine Blades Using Laser Cladding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20I.%20Jafar">Sami I.

The unique of political advice in Islam that Muslim already have the strong and fulfil example that can be apply in nowadays governance that is the way of political and leadership Prophet Muhammad show in his time. As a political leader, the Prophet Muhammad (PBUH) established a great state whose capital was Madinah. However, his real political leadership was in the realm of morality and spirituality in which he conducted himself perfectly in situations of weakness as well as strength. His way of dealing in Makkah and Madinah indicates his great political leadership. Based on fact nowadays some of the country not practicing the proper way to advice to rulers or governance that make a lot of madness around them. This paper also aims the concept and the proper way that can be following to all Muslim to advising by the politeness, justice and kindness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadith" title="Hadith">Hadith</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20advice" title=" political advice"> political advice</a>, <a href="https://publications.waset.org/abstracts/search?q=Prophet%20Muhammad" title=" Prophet Muhammad"> Prophet Muhammad</a> </p> <a href="https://publications.waset.org/abstracts/73118/the-importance-of-political-advice-in-islam-hadith-thematical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73118.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">437</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">132</span> Liquid Chromatographic Determination of Alprazolam with ACE Inhibitors in Bulk, Respective Pharmaceutical Products and Human Serum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeeda%20Nadir%20Ali">Saeeda Nadir Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Najma%20Sultana"> Najma Sultana</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saeed%20Arayne"> Muhammad Saeed Arayne</a>, <a href="https://publications.waset.org/abstracts/search?q=Amtul%20Qayoom"> Amtul Qayoom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present study describes a simple and a fast liquid chromatographic method using ultraviolet detector for simultaneous determination of anxiety relief medicine alprazolam with ACE inhibitors i.e; lisinopril, captopril and enalapril employing purospher star C18 (25 cm, 0.46 cm, 5 µm). Separation was achieved within 5 min at ambient temperature via methanol: water (8:2 v/v) with pH adjusted to 2.9, monitoring the detector response at 220 nm. Optimum parameters were set up as per ICH (2006) guidelines. Calibration range was found out to be 0.312-10 µg mL-1 for alprazolam and 0.625-20 µg mL-1 for all the ACE inhibitors with correlation coefficients > 0.998 and detection limits 85, 37, 68 and 32 ng mL-1 for lisinopril, captopril, enalapril and alprazolam respectively. Intra-day, inter-day precision and accuracy of the assay were in acceptable range of 0.05-1.62% RSD and 98.85-100.76% recovery.

Understanding each generation and their growing needs will equip the workforce for when the Boomers prepare for retirement, with majority of nursing leadership positions to be potentially replaced with Gen Y nurses. In SA Medical Imaging(SAMI), at Flinders Medical Centre (FMC), it has been proven that despite challenges in succession planning, Gen Y nurse leaders are able to overcome these obstacles and provide the leadership necessary to meet the changing needs in healthcare and across organisations. Changing the culture in radiology nursing has been seen as an obstacle due to the historical nursing practices and resistance to adapt to current/future practice. As radiology advances so does the role of the nurse in imaging, this has required resilience and strong support through leadership as we change and develop the culture to keep up with the evolution of technology and standard of patient care. As a result of supporting Gen Y nurses in leadership roles, SAMI, FMC has seen a positive change in culture by creating a healthy work environment which has allowed Gen Y nurses to make long lasting contributions to the nursing profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=changing%20culture" title="changing culture">changing culture</a>, <a href="https://publications.waset.org/abstracts/search?q=Generation%20Y" title=" Generation Y"> Generation Y</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a> </p> <a href="https://publications.waset.org/abstracts/124659/generation-y-leaders-in-radiology-nursing-changing-the-culture-by-understanding-the-challenges-of-a-multi-generational-workforce" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124659.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">130</span> Rubric in Vocational Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azmanirah%20Ab%20Rahman">Azmanirah Ab Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamil%20Ahmad"> Jamil Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruhizan%20Muhammad%20Yasin"> Ruhizan Muhammad Yasin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rubric is a very important tool for teachers and students for a variety of purposes.

The optimized operating conditions were feed and permeate flow, 40 and 7 m³/d, feed pressure 2.68 bar and flux rate 37.7 l/m2.h. The permeate water was drinkable according to Egyptian Ministerial decree 458/2007 for the tested parameters (physic-chemical, heavy metals, organic, algal, bacteriological and parasitological).

The study determined that increasing the size or number of bolts can notably improve the fatigue life of bolted flange connections. Additionally, the curves derived from the assessment data demonstrated a steeper slope for a greater number of bolts, indicating that the percentage increase of adding bolts is not consistent for each additional bolt. Instead, the percentage increment rises exponentially when increasing the number of bolts. However, selecting the most suitable design improvement strategy depends on the specific circumstances. In the majority of cases, the study observed that increasing the number of bolts resulted in significant improvements in fatigue life, regardless of the size of the bolts used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20tower" title="wind turbine tower">wind turbine tower</a>, <a href="https://publications.waset.org/abstracts/search?q=flanged%20connection" title=" flanged connection"> flanged connection</a>, <a href="https://publications.waset.org/abstracts/search?q=number%20of%20bolts" title=" number of bolts"> number of bolts</a>, <a href="https://publications.waset.org/abstracts/search?q=size%20of%20bolts" title=" size of bolts"> size of bolts</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20life" title=" fatigue life"> fatigue life</a> </p> <a href="https://publications.waset.org/abstracts/167960/investigating-fatigue-life-in-bolted-flange-connection-in-wind-turbine-towers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167960.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">80</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">114</span> Bleaching Liquor Recovery of Batch-Wise and Continuous Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Saleemi">Sidra Saleemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arsalan%20Khan"> Arsalan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Urooj%20Baig"> Urooj Baig</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahir%20Jamil"> Tahir Jamil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, it was examined that some residual amount of bleaching chemicals left in the liquor, this amount is more in Batch-wise process as compared to continuous process.

The prepared samples have a mixture of cubic perovskite structure (main) and orthorhombic phases. The effect of different loads of copper as dopant on the structural properties as well as the photocatalytic activity was demonstrated. The lattice parameter and the unit cell volume of the prepared materials are given. Doping with copper increased the photocatalytic activity of BaFeO3 several times in abstraction of hazardous atrazine that causes acute problems in drinking water treatment facilities.

Biomass has been recognized as a capable resource because it is plentifully available and in principle carbon dioxide neutral. Present study focuses on utilization date seeds oil for synthesizing high value fuels formulations such as green diesel and jet fuel. The hydrodeoxygenation of date seeds oil occurred to be highly efficient at following operating conditions temperature 300°C pressure 10bar with continuous stirring at 500 rpm. Products characterization revealed the efficiency of hydrodeoxygenation by formation of linear hydrocarbons (paraffin) in larger fraction. Based on the type of components in product oil it was calculated that maximum fraction lies within the range of green diesel 72.78 % then jet fuel 28.25 % by using Pt/C catalyst. It can be concluded that waste date seeds oil has potential to be used for obtaining high value products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=date%20seeds" title="date seeds">date seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodeoxygenation" title=" hydrodeoxygenation"> hydrodeoxygenation</a>, <a href="https://publications.waset.org/abstracts/search?q=paraffin" title=" paraffin"> paraffin</a>, <a href="https://publications.waset.org/abstracts/search?q=deoxygenation" title=" deoxygenation"> deoxygenation</a> </p> <a href="https://publications.waset.org/abstracts/55385/synthesis-of-highly-valuable-fuel-fractions-from-waste-date-seeds-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55385.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">264</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">111</span> Adaptive Cooperative Control of Nonholonomic Mobile Robot Based on Immersion and Invariance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imil%20Hamda%20Imran">Imil Hamda Imran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20El%20Ferik"> Sami El Ferik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with adaptive cooperative control of non holonomic mobile robot moved together in a given formation.

Two Barajeels (Wind Catchers) are designed and located at both extreme ends of the built unit. The two wind catchers are made as inlet and outlet for the air movement where the rate of air changes at its best. To validate the usage of the wind catchers a CFD Software was used to simulate the operation of the wind catchers for natural ventilations for average wind speed of 2 m/s.
