The results were as follows, the average MK and LZB were 92.84 (kg) and 1.16, respectively. MK was highly significantly affected by each parity, age of ewe, year of lambing, and lactation period, while only the year of lambing had a significant effect on LZB. The heritability and repeatability were 0.07 and 0.10 for MK, while it was 0.05 and 0.25 for LZB. The genetic and phenotypic correlations were 0.17 and 0.02 between MK and LZB, respectively. The research concluded that the herd is genetically homozygous and therefore needs to increase genetic variance by introducing LZB-improved rams and selecting females from dams who achieved at least four parties to increase returns in drylands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awassi%20sheep" title="Awassi sheep">Awassi sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20parameters" title=" genetic parameters"> genetic parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=litter%20size" title=" litter size"> litter size</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20yield" title=" milk yield"> milk yield</a> </p> <a href="https://publications.waset.org/abstracts/149418/genetic-and-non-genetic-evaluation-of-milk-yield-and-litter-size-of-awassi-sheep-in-drylands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149418.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">121</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">15</span> A Pragmatic Reading of the Verb "Kana" and Its Meanings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20M.%20H.%20Said%20Najjar">Manal M.

Kana was considered as a verb, a particle, or a quasi-verb by different scholars; others saw it as an auxiliary verb; while some other scholars categorized kana as one of the incomplete verbs or (Afa’al naqisa) based on two different claims: first, a considerable group of grammarians saw kana as fie’l naqis or an incomplete verb since it indicates time, but not the event or action itself. Second, kana requires a predicate (xabar) to complete the meaning, i.e., it does not suffice itself with a noun in the nominal sentence. This study argues that categorizing the verb kana as fie’l naqis or an incomplete verb is inaccurate and confusing since the term “incomplete” does not agree with its characteristics, meanings, and temporal indications. Moreover, interpreting kana as a past verb is also inaccurate. kana كان (derived from the absolute action of being كون) is considered unique and the most comprehensive verb, encompassing all tenses of the past, present, and future within the dimensions of continuity and eternity of all possible actions under “being”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pragmatics" title="pragmatics">pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=kana" title=" kana"> kana</a>, <a href="https://publications.waset.org/abstracts/search?q=context" title=" context"> context</a>, <a href="https://publications.waset.org/abstracts/search?q=Arab%20grammarians" title=" Arab grammarians"> Arab grammarians</a>, <a href="https://publications.waset.org/abstracts/search?q=meaning" title=" meaning"> meaning</a>, <a href="https://publications.waset.org/abstracts/search?q=fie%E2%80%99l%20naqis" title=" fie’l naqis"> fie’l naqis</a> </p> <a href="https://publications.waset.org/abstracts/153560/a-pragmatic-reading-of-the-verb-kana-and-its-meanings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153560.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">94</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">14</span> Robust Features for Impulsive Noisy Speech Recognition Using Relative Spectral Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Rahali">Hajer Rahali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zied%20Hajaiej"> Zied Hajaiej</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Ellouze"> Noureddine Ellouze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of speech parameterization is to extract the relevant information about what is being spoken from the audio signal.

The jaesckeanadiol-3-p-hydroxyphenylpropanoate, a hemi-synthetic analogue of the natural phytoestrogen ferutinin (jaesckeanadiol-p-hydroxybenzoate), is designed to be devoid of estrogenic activity. This analogue induces a cytotoxic effect 30 times higher than that of ferutinin towards MCF-7 breast cancer cell line. We compared these two compounds with respect to their effect on proliferation, cell cycle distribution and cancer stem-like cells in the MCF-7 cell line. Treatment with ferutinin (30 μM) and its analogue (1 μM) produced a significant accumulation of cells at the pre G0/G1 cell cycle phase and triggered apoptosis. Importantly, this compound retains its anti-proliferative activity against breast cancer stem/progenitor cells that are naturally insensitive to ferutinin at the same dose. These results position ferutinin analogue as an effective compound inhibiting the proliferation of estrogen-dependent breast cancer cells and consistently targeting their stem-like cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferutinin" title="ferutinin">ferutinin</a>, <a href="https://publications.waset.org/abstracts/search?q=hemi-synthetic%20analogue" title=" hemi-synthetic analogue"> hemi-synthetic analogue</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=estrogen" title=" estrogen"> estrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%2Fprogenitor%20cells" title=" stem/progenitor cells"> stem/progenitor cells</a> </p> <a href="https://publications.waset.org/abstracts/98903/a-ferutinin-analogue-with-enhanced-potency-and-selectivity-against-estrogen-receptor-positive-breast-cancer-cells-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98903.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">189</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">12</span> Pharmaceutical Evaluation of Five Different Generic Brands of Prednisolone </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20A.%20Ben%20Ahmed">Asma A.

Use of generic medicines has been increasing in recent years, primarily as a cost saving measure in healthcare provision. Generic medicines are typically 20 – 90 % cheaper than originator equivalents. Physicians often continue to prescribe brand-name drugs to their patients even when less expensive pharmacologically equivalent generic drugs are available. Because generics are less expensive than their brand-name counterparts, the cost-savings to the patient is not the only factor that physicians consider when choosing between generic and brand-name drugs. Unfortunately Physicians in general and Libyan Physicians in particular tend to prescribe brand-name drugs, even without evidence of their therapeutic superiority, because neither they nor their insured patients bear these drugs’ increased cost with respect to generic substitutes. This study is to compare the quality of five different prednisolone tablets of the same strength from different companies under different trade names: Julphar, October pharma, Akums, Actavis, Pfizer compared them with pure prednisolone reference (BPCRS). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20control" title="quality control">quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20analysis" title=" pharmaceutical analysis"> pharmaceutical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=generic%20medicines" title=" generic medicines"> generic medicines</a>, <a href="https://publications.waset.org/abstracts/search?q=prednisolone" title=" prednisolone "> prednisolone </a> </p> <a href="https://publications.waset.org/abstracts/19693/pharmaceutical-evaluation-of-five-different-generic-brands-of-prednisolone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19693.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">514</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">11</span> Competitive Adsorption of Heavy Metals onto Natural and Activated Clay: Equilibrium, Kinetics and Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Khalfa">L.

Therefore, we are interested to investigate the efficiency of natural clay minerals collected from south Tunisia and their modified form using sulfuric acid in the removal of toxic metal ions: Zn(II) and Pb(II) from synthetic waste water solutions. The obtained results indicate that metal uptake is pH-dependent and maximum removal was detected to occur at pH 6. Adsorption equilibrium is very rapid and it was achieved after 90 min for both metal ions studied. The kinetics results show that the pseudo-second-order model describes the adsorption and the intraparticle diffusion models are the limiting step. The treatment of natural clay with sulfuric acid creates more active sites and increases the surface area, so it showed an increase of the adsorbed quantities of lead and zinc in single and binary systems. The competitive adsorption study showed that the uptake of lead was inhibited in the presence of 10 mg/L of zinc. An antagonistic binary adsorption mechanism was observed. These results revealed that clay is an effective natural material for removing lead and zinc in single and binary systems from aqueous solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20clay" title=" activated clay"> activated clay</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic%20study" title=" kinetic study"> kinetic study</a>, <a href="https://publications.waset.org/abstracts/search?q=competitive%20adsorption" title=" competitive adsorption"> competitive adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a> </p> <a href="https://publications.waset.org/abstracts/48926/competitive-adsorption-of-heavy-metals-onto-natural-and-activated-clay-equilibrium-kinetics-and-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48926.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">223</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">10</span> Inhibitory Effect of Potential Bacillus Probiotic Strains against Pathogenic Bacteria and Yeast Isolated from Oral Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fdhila%20Walid">Fdhila Walid</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayar%20Sihem"> Bayar Sihem</a>, <a href="https://publications.waset.org/abstracts/search?q=Khouidi%20Bochra"> Khouidi Bochra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C3%A2touk%20Fethi"> Maâtouk Fethi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Amor%20Feten"> Ben Amor Feten</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Hentati"> Hajer Hentati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdhi%20Abdelkarim"> Mahdhi Abdelkarim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presence of resistant bacteria in the oral cavity can be the major cause of dental antibiotic prophylaxis failure. Multidrug efflux has been described for many organisms, including bacteria and fungi as part of their drugs resistance strategy. The potential use of probiotic bacteria can be considered as a new alternative in the prevention or cure of oral cavity diseases. In this study, different Bacillus strains isolated from the environment were isolated and characterized using biochemical and molecular procedures. The inhibitory activity against different pathogenic bacteria and yeast strains was tested using diffusion agar assay method. Our data revealed that the tested strains have an antimicrobial effect against the pathogenic strains such as Streptococcus mutants. The inhibitory effect was variable depending from the probiotic and pathogenic strains. The obtained result demonstrated that Bacillus can be used as a potential candidates probiotic and help in the prevention and treatment of oral infections, including dental caries, periodontal disease and halitosis. Our data, partly encourage the use of probiotic strains because they do not produce acid which can contribute to faster installation decay and these are spore-forming bacteria that can withstand the stress of the oral cavity (acids, alkalis, and salty foods). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotic" title="probiotic">probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenic%20bacteria" title=" pathogenic bacteria"> pathogenic bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20cavity" title=" oral cavity"> oral cavity</a> </p> <a href="https://publications.waset.org/abstracts/1415/inhibitory-effect-of-potential-bacillus-probiotic-strains-against-pathogenic-bacteria-and-yeast-isolated-from-oral-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1415.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">378</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">9</span> Reliability Based Analysis of Multi-Lane Reinforced Concrete Slab Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mahmoud">Ali Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadi%20Najjar"> Shadi Najjar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mounir%20Mabsout"> Mounir Mabsout</a>, <a href="https://publications.waset.org/abstracts/search?q=Kassim%20Tarhini"> Kassim Tarhini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Empirical expressions for estimating the wheel load distribution and live-load bending moment are typically specified in highway bridge codes such as the AASHTO procedures. The purpose of this paper is to analyze the reliability levels that are inherent in reinforced concrete slab bridges that are designed based on the simplified empirical live load equations in the AASHTO LRFD procedures. To achieve this objective, bridges with multi-lanes (three and four lanes) and different spans are modeled using finite-element analysis (FEA) subjected to HS20 truck loading, tandem loading, and standard lane loading per AASHTO LRFD procedures. The FEA results are compared with the AASHTO LRFD moments in order to quantify the biases that might result from the simplifying assumptions adopted in AASHTO. A reliability analysis is conducted to quantify the reliability index for bridges designed using AASHTO procedures. To reach a consistent level of safety for three- and four-lane bridges, following a previous study restricted to one- and two-lane bridges, the live load factor in the design equation proposed by AASHTO LRFD will be assessed and revised if needed by alternating the live load factor for these lanes. The results will provide structural engineers with more consistent provisions to design concrete slab bridges or evaluate the load-carrying capacity of existing bridges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis%20of%20concrete%20bridges" title="reliability analysis of concrete bridges">reliability analysis of concrete bridges</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis" title=" reliability analysis"> reliability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20bridge%20design" title=" reinforced concrete bridge design"> reinforced concrete bridge design</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20carrying%20capacity" title=" load carrying capacity"> load carrying capacity</a> </p> <a href="https://publications.waset.org/abstracts/73454/reliability-based-analysis-of-multi-lane-reinforced-concrete-slab-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73454.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">341</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">8</span> Practice, Observation, and Gender Effects on Students’ Entrepreneurial Skills Development When Teaching through Entrepreneurship Is Adopted: Case of University of Tunis El Manar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Chaker%20Ben%20Hadj%20Kacem">Hajer Chaker Ben Hadj Kacem</a>, <a href="https://publications.waset.org/abstracts/search?q=Thouraya%20Slama"> Thouraya Slama</a>, <a href="https://publications.waset.org/abstracts/search?q=N%C3%A9jiba%20El%20Yetim%20Zribi"> Néjiba El Yetim Zribi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzes the effects of gender, affiliation, prior work experience, social work, and vicarious learning through family role models on entrepreneurial skills development by students when they have learned through the entrepreneurship method in Tunisia.

The article assesses the impact of these combinations by comparing their effects on the development of thirteen students’ entrepreneurial competencies, namely entrepreneurial mindset, core self-evaluation, entrepreneurial attitude, entrepreneurial knowledge, creativity, financial literacy, managing ambiguity, marshaling of resources, planning, teaching methods, entrepreneurial teachers, innovative employee, and Entrepreneurial intention. Authors use a two-sample independent t-test to make the comparison, and the results indicate that, when combined with teaching through the entrepreneurship method, students with prior work experience developed better six entrepreneurial skills; students with social work developed better three entrepreneurial skills, men developed better four entrepreneurial skills than women.

The methodology used consists of estimating a panel of the nine main destinations of the Tunisian diaspora in Europe between 1994 and 2014 in order to better value the net effect of these migratory financial flows on unemployment through population growth. The empirical results show that the main factors explaining the decision to emigrate are the economic factors related mainly to the income differential, the demographic factors related to the differential age structure of the origin and host populations, and the cultural factors linked basically to the mastery of the language. Indeed, the stock of migrants is one of the main determinants of the transfer of migratory funds to Tunisia. But there are other variables that do not lack importance such as the economic conditions linked by the host countries. This shows that Tunisian migrants react more to economic conditions in European countries than in Tunisia. The economic situation of European countries dominates the numbers of emigrants as an explanatory factor for the amount of transfers from Tunisian emigrants to their country of origin. Similarly, it is clear that there is an indirect effect of transfers on unemployment in Tunisia. This suggests that the demographic transition conditions the effects of transferring funds on the level of unemployment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demographic%20changes" title="demographic changes">demographic changes</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20migration" title=" international migration"> international migration</a>, <a href="https://publications.waset.org/abstracts/search?q=labor%20market" title=" labor market"> labor market</a>, <a href="https://publications.waset.org/abstracts/search?q=remittances" title=" remittances"> remittances</a> </p> <a href="https://publications.waset.org/abstracts/100738/remittances-unemployement-and-demographic-changes-between-tunisia-and-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100738.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">150</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">6</span> The Redundant Kana: A Pragmatic Reading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20%20Mohammed%20Hisham%20Said%20Najjar">Manal Mohammed Hisham Said Najjar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Arab Grammarians shed light on the redundant kana (was) and gave it a considerable attention. However, their considerations and interpretations pertaining to using this verb varied: is it used to determine tense? Or used for further emphasis or for another function? Does it have a syntactic function? Morphologically, could it be used in other forms than the past? In addition, Arab Grammarians discussed the possibility of using kana to locate itself in between the syntactic constructs of a sentence, a phrase, or a collocation. Others questioned its position whether it is in initial or final. This study found out that the redundant kana (was) is cited in Quran and was used by the Arabs in their speech and poetry. This redundant kana, whether used in initial position or in a final position, or in between the constructs of a sentence, a phrase, or a collocation, implies pragmatic meanings intended by the speaker or the poet to serve different functions, such as to indicate the past tense, to provide emphasis, and to refer to the continuity of the effect and meaning of a verb or adjective. The study concludes that this verb kana can be utilized in different contexts to achieve a specific effect as did the old Arabs who used it to add specific shades of meanings. Kana as a redundant word could be added to further highlight the meaning aimed at in a specific utterance. In addition, this verb can be used in both the past and the present morphological form; and its availability in an utterance could be functional and could not be. In other words, the study found out that the redundant kana can be used in various positions in an utterance, initial, final, or in between a syntactic structure, provided that this use is pragmatically functional. In conclusion, this paper seeks to invite the scholars of the Arabic language to coin a new term which is the “pragmatic kana” to replace the term “kana alzae’da (redundant kana)” which might mean that its use is redundant and void of significance – a fact that is illogical due to its recurrent use in the Holy Quran.

Despite this, distant spread is exceptionally rare. Metastatic BCC (mBCC) is estimated to occur in 0.0028 - 0.5%. it aim to illustrate with the aid of histological slides, a case of mBCC occurring in a fit and well 67-year-old. Initial diagnosis of desmoplastic BCC was made in 2006 from a scalp biopsy with the lesion then being excised. Re-excision of local recurrence was undertaken the following year. In 2014 the patient presented with an ipsilateral level 2a mass. Fine Needle Aspiration raised the suspicion of metastatic carcinoma. The patient had excision of two nodes from the left neck alongside pharyngeal tonsillectomy and tongue base biopsies. Histologically, the nodes closely resembled the immunophenotype of the initial scalp lesion. The patient subsequently had a modified radical neck dissection, and residual mBCC was excised from the left Sternocleidomastoid muscle. In 2023 the patient developed haematuria. On further investigation bilateral lung lesions on CT were noted with subsequent biopsy confirming mBCC. Spinal and renal lesions have also been found. Histopathology showed clear resemblance of the lung metastases to both those in the neck and the primary (scalp BCC) – with no squamous differentiation seen. The time span from primary to occurrence of lung metastasis (18 years) affirms the indolent and slow growing nature of BCC.  This case fulfils Lattes and Kessler diagnostic criteria. High risk cases are described as those with advanced local presentation, primary tumour on the Head and Neck and locally recurrent lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BCC" title="BCC">BCC</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=rare" title=" rare"> rare</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20cancer" title=" skin cancer"> skin cancer</a> </p> <a href="https://publications.waset.org/abstracts/184478/a-rare-case-of-metastatic-basal-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184478.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">57</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">4</span> Seismic Reflection Highlights of New Miocene Deep Aquifers in Eastern Tunisia Basin (North Africa)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mourad%20B%C3%A9dir">Mourad Bédir</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Khomsi"> Sami Khomsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakim%20Gabtni"> Hakim Gabtni</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Azaiez"> Hajer Azaiez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramzi%20Gharsalli"> Ramzi Gharsalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadh%20Chebbi"> Riadh Chebbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eastern Tunisia is a semi-arid area; located in the northern Africa plate; southern Mediterranean side. It is facing water scarcity, overexploitation, and decreasing of water quality of phreatic water table. Water supply and storage will not respond to the demographic and economic growth and demand. In addition, only 5 109 m3 of rainwater from 35 109 m3 per year renewable rain water supply can be retained and remobilized. To remediate this water deficiency, researches had been focused to near new subsurface deep aquifers resources. Among them, Upper Miocene sandstone deposits of Béglia, Saouaf, and Somaa Formations. These sandstones are known for their proven Hydrogeologic and hydrocarbon reservoir characteristics in the Tunisian margin. They represent semi-confined to confined aquifers. This work is based on new integrated approaches of seismic stratigraphy, seismic tectonics, and hydrogeology, to highlight and characterize these reservoirs levels for aquifer exploitation in semi-arid area. As a result, five to six third order sequence deposits had been highlighted. They are composed of multi-layered extended sandstones reservoirs; separated by shales packages. These reservoir deposits represent lowstand and highstand system tracts of these sequences, which represent lowstand and highstand system tracts of these sequences. They constitute important strategic water resources volumes for the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title="Tunisia">Tunisia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hydrogeology" title=" Hydrogeology"> Hydrogeology</a>, <a href="https://publications.waset.org/abstracts/search?q=sandstones" title=" sandstones"> sandstones</a>, <a href="https://publications.waset.org/abstracts/search?q=basin" title=" basin"> basin</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=aquifers" title=" aquifers"> aquifers</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a> </p> <a href="https://publications.waset.org/abstracts/142805/seismic-reflection-highlights-of-new-miocene-deep-aquifers-in-eastern-tunisia-basin-north-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142805.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">178</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">3</span> Obtaining Norms for Arabic Translated Version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Neuropsychological Battery in Normal Elderly Omanis Attending a Tertiary Hospital in Oman</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Alobaidy">Ammar Alobaidy</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamees%20Alsawafi"> Lamees Alsawafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Almawali"> Malak Almawali</a>, <a href="https://publications.waset.org/abstracts/search?q=Balqees%20Alabri"> Balqees Alabri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Alhamrashdi"> Hajer Alhamrashdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: There is scarce data in the literature concerning the use of Arabic version neuron psychological cognitive tests in the geriatric age group of the Omani population. Objectives: Our aim is to obtain norms for normal elderly Omanis assessed by The Consortium to Establish a Registry for Alzheimer's disease (CERAD) neuro psychological battery and to compare these norms with other studies in the literature. Methods: 84 attendants and visitors of in-patients at Sultan Qaboos University Hospital, elder than 55 years, were interviewed. All participants were assessed by Dementia Rating Scale & Geriatric Depression Scale to ensure the integrity of their activities of daily living and the absence of depression, respectively. The performance of all participants in the CERAD battery was rated by a single rater to optimize the inter-rater reliability. Results: The cut-point for average performance in CERAD battery is dependent on the age, sex, and level of education and cannot be set as a single cut-point for all elderly Omanis. Conclusion: This study has shown the effect of age, sex, and level of education on the cognitive performance of normal elderly Omanis. The normative data obtained from this study can be utilized to differentiate between the cognitive decline of normal aging and the cognitive impairment due to various neuro cognitive disorders in the elderly Omanis, and probably culturally similar Arabic speaking communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CERAD" title="CERAD">CERAD</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropsychological%20battery" title=" neuropsychological battery"> neuropsychological battery</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20aging" title=" normal aging"> normal aging</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly%20Omanis" title=" elderly Omanis"> elderly Omanis</a> </p> <a href="https://publications.waset.org/abstracts/18881/obtaining-norms-for-arabic-translated-version-of-the-consortium-to-establish-a-registry-for-alzheimers-disease-cerad-neuropsychological-battery-in-normal-elderly-omanis-attending-a-tertiary-hospital-in-oman" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18881.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">371</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">2</span> Biocontrol Effectiveness of Indigenous Trichoderma Species against Meloidogyne javanica and Fusarium oxysporum f. sp. radicis lycopersici on Tomato </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajji%20Lobna">Hajji Lobna</a>, <a href="https://publications.waset.org/abstracts/search?q=Chattaoui%20Mayssa"> Chattaoui Mayssa</a>, <a href="https://publications.waset.org/abstracts/search?q=Regaieg%20Hajer"> Regaieg Hajer</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27Hamdi-Boughalleb%20Naima"> M'Hamdi-Boughalleb Naima</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhouma%20Ali"> Rhouma Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Horrigue-Raouani%20Najet"> Horrigue-Raouani Najet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, three local isolates of <em>Trichoderma</em> (Tr1: <em>T. viride</em>, Tr2: <em>T. harzianum</em> and Tr3: <em>T. asperellum</em>) were isolated and evaluated for their biocontrol effectiveness under <em>in vitro</em> conditions and in greenhouse. <em>In vitro</em> bioassay revealed a biopotential control against <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em> and <em>Meloidogyne javanica </em>(RKN) separately. All species of <em>Trichoderma</em> exhibited biocontrol performance and (Tr1) <em>Trichoderma viride</em> was the most efficient. In fact, growth rate inhibition of <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em> (FORL) was reached 75.5% with Tr1. Parasitism rate of root-knot nematode was 60% for juveniles and 75% for eggs with the same one. Pots experiment results showed that Tr1 and Tr2, compared to chemical treatment, enhanced the plant growth and exhibited better antagonism against root-knot nematode and root-rot fungi separated or combined. All <em>Trichoderma</em> isolates revealed a bioprotection potential against <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em>. When pathogen fungi inoculated alone, Fusarium wilt index and browning vascular rate were reduced significantly with Tr1 (0.91, 2.38%) and Tr2 (1.5, 5.5%), respectively. In the case of combined infection with Fusarium and nematode, the same isolate of <em>Trichoderma</em> Tr1 and Tr2 decreased Fusarium wilt index at 1.1 and 0.83 and reduced the browning vascular rate at 6.5% and 6%, respectively. Similarly, the isolate Tr1 and Tr2 caused maximum inhibition of nematode multiplication. Multiplication rate was declined at 4% with both isolates either tomato infected by nematode separately or concomitantly with Fusarium. The chemical treatment was moderate in activity against <em>Meloidogyne javanica</em> and <em>Fusarium oxysporum f. sp. </em><em>radicis lycopersici</em> alone and combined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trichoderma%20spp." title="trichoderma spp.">trichoderma spp.</a>, <a href="https://publications.waset.org/abstracts/search?q=meloidogyne%20javanica" title=" meloidogyne javanica"> meloidogyne javanica</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20oxysporum%20f.sp.radicis%20lycopersici" title=" Fusarium oxysporum f.sp.radicis lycopersici"> Fusarium oxysporum f.sp.radicis lycopersici</a>, <a href="https://publications.waset.org/abstracts/search?q=biocontrol" title=" biocontrol"> biocontrol</a> </p> <a href="https://publications.waset.org/abstracts/50717/biocontrol-effectiveness-of-indigenous-trichoderma-species-against-meloidogyne-javanica-and-fusarium-oxysporum-f-sp-radicis-lycopersici-on-tomato" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50717.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">278</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">1</span> Prednisone and Its Active Metabolite Prednisolone Attenuate Lipid Accumulation in Macrophages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Jeries">H.

The role of glucocorticoids (GCs) in cardiovascular diseases including atherosclerosis is highly controversial, and their impact on macrophage foam cell formation is still unknown. Our aim was to investigate the effects of prednisone or its active metabolite, prednisolone, on macrophage oxidative stress and lipid metabolism using in-vivo, ex-vivo and in-vitro systems. Methods: The in-vivo study included C57BL/6 mice which were intraperitoneally injected with prednisone or prednisolone (5mg/kg) for 4 weeks, followed by lipid metabolism analyses in the mice aorta, and in peritoneal macrophages (MPM). In the ex-vivo study, we analyzed the effect of serum samples obtained from 9 healthy volunteers before or after treatment with oral prednisone (20mg for 5 days), on J774A.1 macrophage atherogenicity. In-vitro studies were conducted using J774A.1 macrophages, human monocyte derived macrophages (HMDM) and fibroblasts. Cells were incubated with increasing concentrations (0-200 ng/ml) of prednisone or prednisolone, followed by determination of cellular oxidative status, triglyceride and cholesterol metabolism. Results: Prednisone or prednisolone treatment resulted in a significant reduction in triglycerides and mainly in cholesterol cellular accumulation in MPM or in J774A.1 macrophages incubated with human serum. Similar resulted were noted in HMDM or in J774A.1 macrophages which were directly incubated with the GCs. These effects were associated with GCs inhibitory effect on triglycerides and cholesterol biosynthesis rates, throughout downregulation of diacylglycerol acyltransferase1 (DGAT1) expression, and of the sterol regulatory element binding protein (SREBP2) and HMGCR expression, respectively. In parallel to prednisone or prednisolone induced reduction in macrophage triglyceride content, paraoxonase 2 (PON2) expression was significantly upregulated. GCs-induced reduction of cellular triglyceride and cholesterol mass was mediated by the GCs receptors on macrophages since the GCs receptor antagonist (RU 486) abolished these effects. In fibroblasts, unlike macrophages, prednisone or prednisolone showed no anti-atherogenic effects. Conclusions: Prednisone or prednisolone are anti-atherogenic since they protected macrophages from lipid accumulation and foam cell formation. <p class="card-text"><strong>Keywords:</strong> <a
