Purpose:
The objective of this investigation is to study prosthodontics and internal components resistance to the masticatory stress and considering different force directions by using Finite Element Method analysis (FEM). The structural materials of the components are usually Titanium alloy grade 4 or 5 and thus, guarantee the integration of the fixture in the bone due to the osteointegration phenomena. Even if the long-term dental implant survival rate is easy to be obtained and confirmed by numerous researches, the related clinical success, due to the alteration of the mechanical and prosthodontics components is still controversial.

Methods:
By applying engineering systems of investigations like FEM and Von Mises analyses, it has been investigated how dental implant material was held against the masticatory strength during the dynamic masticatory cycles. A three-dimensional system involved fixture, abutment and the connection screws, which were created and analyzed. The elastic features of the materials used in the study were taken from recent literature data.

Results:
Data revealed a different response for both types of devices, although implant neck and dental abutment showed better results for all conditions of loading while the abutment screw represented aweak point of the system.

Conclusion:
The data of this virtual model showed all the features of different prosthetic retention systems under the masticatory load. Clinicians should find better prosthetic balance in order to better distribute the stress over the component and to guarantee patients’ clinical long-term results.
Designing Piled Foundations with a Full 3D Model
Authors: Barbosa V. D. , Galgoul N. S. 
Published: March 2018

Background:The analysis of piled foundations, where horizontal environmental loads play a very important role, has taken foundation design a step further in the 1970s and 80s. Nonlinear analyses considering P-y, T-z and Q-z curves became the state-of-the-art which also included group effect calculations thanks to an approximation proposed by [1] on the [2] equations. For some reason, however, foundation design continued to be refined using finite element calculations, but the corresponding developments never made their way into the main offshore platform design codes such as [3,4].Objective:Considering the enormous advantage that this brings for topics such as group effect and negative friction, it is obvious that opening the offshore market to this enhancement is totally desirable. This is exactly what this paper is trying to achieve.Method:In order to increase the accuracy of the prediction of piled foundations lateral displacements when group effect is considerable, a complete 3D model will be proposed using the finite element method and compared to the codes’ model and also experimental data.Results:The model in DIANA showed good performance in comparison to the codes’ model and experimental data for the single pile. When the pile group model, when the codes’ have known deficiencies, was tested, both efforts on each pile and mean displacement of the pile group fit the experimental data. However, the behavior of each pile of the group, if separately analyzed, didn’t fit many experimental data, which was attributed to the soil model utilized.Conclusion:This improved modeling procedure has been proven to improve the lateral displacement prediction of a piled foundation when group effect is considerable, when compared to codes [3,4] proposed models. However, the study of more accurate soil models could help on achieving more realistic results.

Chromium exposure and the kidney damage risk among electroplating workersPurposeThis study was carried out to investigate the kidney damage risk due to chromium exposure at the workplace.Method33 electroplating workers and 33 control subjects with no history of occupational exposure to chromium in Makassar were involved. Chromium levels in urine were measured with atomic absorption spectrometry. ResultsUrine from exposed workers contained higher levels of chromium, when compared with those obtained in the control group. Furthermore, there was a direct relationship was obtained between the amount of chromium and kidney damage. Kidney damage was associated with the existence of chromium level in urine. Electroplating work environments increased the high risk of chromium exposure. Workers exposed for long periods of time result in a higher level of accumulated exposure in the body. The findings of this study indicated that there was higher level of chromium exposure in electroplating workers with kidney damage.ConclusionThis study suggested the labor office to closely monitor chromium emission levels in high risk industries. Meanwhile, industry owners need to ensure that every worker uses personal protective equipment to reduce risk.

Community perception of measles immunization in SlemanPurposeThis study conducted to explore the community’s perception of measles immunization in Sleman.MethodsA phenomenological study was conducted involving interviews of the head of neighborhood’s ladies who were highly respected by their citizens, mothers with toddlers but refused immunizations, immunized toddler mothers, health workers who did not immunize their children based on information from FGDs of mothers who refused immunization, a toddler father who does not allow his child to be immunized, community leaders and religious leaders, in the village of Sukoharjo whose area has been infected with measles outbreaks. ResultsThe study found that first, people perceived that immunization has no benefit and even causes side effects for children’s under-five health. Second, the community perceives that immunization of measles is not mandatory because of the lack of the government's role in enforcing regulations related to measles immunization. Third, the perception of people against measles immunization is influenced by the behavior of health workers and religious leaders. ConclusionsThe side effects of measles immunization, the influence of health workers' behavior and religious figures related to non-immunization against measles, and the lack of government's role in enforcing regulations related to the appeal of measles immunization are the factors that influence community's perception and a decision of not doing measles immunization. Government appeals related to immunization need to be improved, and in addition, education related to measles hazard should be done to the community, religious leaders and health workers to increase awareness and awareness of the dangers of measles.

Published: March 2018

Clinician scientists play a critical role in bridging research and clinical practice. Unfortunately, the neglect of research training in medical schools has created clinicians who are unable to translate evidence from literature to practice. Furthermore, the erosion of research training in medical education has resulted in clinicians who lack the skills required for successful scientific investigation. To counteract this, the Schulich School of Medicine & Dentistry has made an effort to engage trainees, at all levels, in the research process.
The 2nd Annual Clinician Scientist Trainee Symposium was held in London, Ontario, Canada on August 22, 2017. Organized each year since 2016 by the Schulich Research Office, the symposium features research being conducted by trainees in Schulich’s Clinical Research Training Program. The focus this year was on the current state of clinician-scientist training in Canada and visions for the path ahead.

Published: March 2018

The current study aims at the in-vitro use of 2 types of extracts of Chlorella Vulgaris, one of the most widely known green algae species in the world, to evaluate their effects on biofilm-producing bacteria. In this study, 7 species of algae were isolated from different environments and then diagnosed according to the sources of green algae and greenish algae. Some of these isolates were proliferated under constant laboratory conditions at 25±2 ̊C, 200μm/m2/sec, and 8:16 hours of light: dark using fixed farms. Then, these species were subjected to 2 types of polycarbonate-based solvents (hexane and chloroform). These extracts were tested on E.Coli, Klebsiella, Acinetobacter, Serratia mesccens, St epidermis, S. aureus, Candida albicans, and Aspergills niger. Using different methods of measuring turbidity of the red agar, micrometer plate, spreading Balacar, the effects of these extracts were examined on these microorganisms. Then, the algae were subjected to vertical chromatography to separate active substances. The hexane-based extract was more effective against E. coli, Acinetobacter, St. aureus. On the other hand, the chloroform-based extract showed slight effects on Acinetobacter and C. albicans. The best inhibitory activities were 30mm for Staphylococcus aureus and Serratia and 25mm for E. coli. The lowest inhibition activity was 15mm for Klebsiella and C. albicans. For the chloroform-based extract, the highest rate of inhibition was 20mm for Klebsiella and S. aureus. The lowest inhibition was 10mm for Acinetobacter and C. albicans. Separation method targeted the hexane-based extraction yielded hxan, gasoline group III ethyl estate, gasoline, group IV ethyl ester, methanol group, and methanol. The hexane + 25 ml of benzene and the fourth group of ethyl ester 25 + methanol showed higher inhibition activities against microbes than that using the other three groups. The hexane-based extracts and the related hexane + 25 ml of benzene and the fourth group of ethyl ester 25 + methanol of C. vulgaris were better than the chloroform-based extracts in their effectiveness against the studied microbes using the turbidity measurement method.

EĞİTİM DÜZEYİNİN İŞSİZLİK ÜZERİNDEKİ ETKİSİ GELİŞMİŞ VE GELİŞMEKTE OLAN ÜLKELERİN KARŞILAŞTIRILMASI
Authors: BAĞCI Erdem 
Published: March 2018

Bütün toplumlarda,
işsizlik önemli bir makroekonomik sorundur.
Çünkü işsizliğin
sadece ekonomik sonuçları yoktur, aynı zamanda sosyal boyutları vardır. Bu
nedenle işsizlikle mücadele için otoriteler ekonomik ve sosyal politikalar
oluşturmak zorundadırlar. Bu bağlamda, eğitim düzeyini yükseltmek işsizliği
azaltmaya yönelik önemli bir politikadır. Bu durumda, önemli bir soru karşımıza
çıkmaktadır; "aynı eğitim politikaları farklı ülkelerde aynı sonuçları
verir mi ?" Bu sorunun cevabını bulmak için, bu çalışma yapılmıştır.

Bu çalışmada,
literatür incelenerek, işsizlik ile eğitim düzeyi arasındaki ilişkiyi inceleyen
yirmi adet çalışma incelenmiştir. Gelişmiş ülkelerde yapılan çalışmalar, eğitim
düzeyi artışının işsizliği azalttığı tespit edilirken, gelişmekte olan
ülkelerde yapılan çalışmalarda ise eğitim düzeyi artışının işsizliği
azaltmadığı tespit edilmiştir. Nitekim gelişmiş ülkelerde eğitim durumuna göre
işsizlik trendleri incelenmiştir ve eğitim düzeyi ile işsizlik arasında negatif
bir ilişkinin olduğu tespit edilmiştir. Aynı şekilde, gelişmekte olan ülkelerde
eğitim durumuna göre işsizlik trendleri de incelenmiştir. Eğitim düzeyi daha
yüksek olan bireylerde işsizlik oranının daha yüksek olduğu tespit edilmiştir.
