Published: February 2019

Subsurface soil varies from place to place due to the rock type, its mineral constituents, the climate
of the area, time and other geological activities such as meteorite impact. The process that leads to
the formation of impact crater can cause great variation in the subsurface soil characteristics, which
may have an effect on civil engineering structures. Hence, the need to evaluate the subsurface soil
of the impacted area. In this study, Seismic refraction and borehole data were used to achieve the
aim. The result revealed that the overburden layer inside the crater is dominated by low-velocity
values (&lt; 750 m/s) which correspond with low N-values. Moderate seismic velocity values (750 –
1400 m/s) with moderate to high N-values were predominant for overburden soil within the crater
rim and outside the crater. Slightly, moderately and highly weathered granite was observed at all
survey lines with velocity values ranging from 1200 - 3450 m/s. The low N-values with lowvelocity values obtained inside the crater are indications that the subsurface soil inside the impact
crater area has been deformed and weakened as evident by the presence of brecciation which
occurred during the impact process.

Authors: Batista Corrêa da Costa Márcia Helena , Guimarães Sandra Meire , Castro Bruna Laís 
Published: February 2019

A experiência narrada neste artigo foi desenvolvida a partir da articulação entre pesquisa e extensão universitária, tendo como objeto o projeto "Participação Política e Direito à Cidade". O objetivo central foi criar situações de interlocução da Universidade com os segmentos sociais organizados, atuantes em Conselhos e outras modalidades de associativismo, com vistas a favorecer o entendimento desses atores sobre o direito à cidade. A referência das discussões foi a Reforma Urbana presente na Lei n. 10.257/ 2001, o Estatuto da Cidade, para favorecer o amadurecimento de canais de interlocução entre sociedade civil e poder público local, estimulando processos de participação política voltados para a consolidação de instrumentos de gestão democrática da cidade. As atividades desenvolvidas foram exitosas, entretanto, a dependência dessas instâncias em relação ao poder executivo inviabilizou a continuidade das ações e a autonomia que se buscava para os conselhos na concepção e controle social de políticas.

Authors: Bansal Prerna , Upadhyay Hari Prasad 
Published: February 2019

Background: Diabetes is an important public health problem as global prevalence of diabetes has nearly doubled reflecting an increase in risk factors like overweight or obesity and dyslipidemia. Both obesity and dyslipidemia share a common pathogenesis associated with “insulin resistance”. Thus the aim of this study is to find out correlation between BMI and lipid profile in type 2 diabetics. Materials and Methods: A cross-sectional study was conducted among 136 type 2 diabetes patients visiting the Diabetes Clinic of College of Medical Sciences, Bharatpur, Nepal during Jan-Dec 2017 and who went through lipid profile testing. The informations were taken from hospital records. To find the significant association between categorical variables chi-square test was used. P-value less than 0.05 were considered as statistically significant. To find the association between continuous variables correlation was used. Results: Out of 136 diabetic patients 77.2% of patients were either overweight or obese. 92.6% of patients had dyslipidemia. Among which 58.1% had high TG levels, 56.6% had high LDL levels, 34.6% had high TC levels and 44.9% had low HDL levels. The overall mean ± SD of age was 54.54±12.03 years and of BMI was 28.54±4.57. Positive correlation was seen between BMI with LDL levels and negative correlation with HDL levels. The correlation with other lipid profile parameters were negative. These correlations were found to be statistically not significant. But statistically significant association was seen between gender with weight, total cholesterol and HDL levels. Conclusions: Obesity and dyslipidemia were highly prevalent. As BMI increases LDL levels increases and HDL levels decreases. Also increased weight and abnormal lipid levels of total cholesterol and HDL were found significantly higher among females than males.

Durability studies on vibration-loaded electrical contact systems subjected to tribological stress
Authors: Schautzgy Johannes , Ivanov Yuriy , Kröger Benjamin , Wilde Jürgen 
Published: February 2019

Abstract
Electrical connectors for signal applications in the automotive sector are subjected to stringent requirements. These systems must ensure dependable signal transmission throughout the service life of a vehicle, even under high stress conditions. To this end, redundantly structured contact systems with several lamellas are often used. Stress due to vibrations during vehicle operation can lead to relative displacements between the electrical contact partners, especially in the resonant frequency range of the connector. Fretting corrosion then leads to increased electrical resistance at the connection and to failure of the system when a certain resistance threshold is exceeded. For studying the durability of electrical contacts, a fretting test bench was developed that allows the emulation of stress due to vibrations on a contact system with test frequencies of up to 300 Hz. The Wöhler model was used for describing the durability as a function of the relative motion. The test procedure and evaluation for determining the model parameters were based on the pearl string method. The test unit was qualified as electrically failed if the resistance exceeded the 15 mΩ threshold. The studies showed that the lifetime of the redundantly structured contact system can be described via an analytic approach based on the methodology for determining Wöhler curves. The distribution function was based on a logarithmic normal distribution. With the aid of scanning electron microscopic analyses in combination with element distribution images from energy dispersive X-ray spectroscopy, it was possible to attribute electrical failure to the oxidation of the base material in the wear track.

Abstract
Pre-cracked 304 stainless steel compact tension specimens were repaired by a CO2 laser at the crack tips with the addition of different weight fractions of nano-Al2O3. Crack opening displacements were measured by a digital image correlation system for the evaluation of fracture performance. Microstructures of the repaired areas were examined by scanning electron microscopy equipped with an energy dispersive spectrometer. Results indicated that laser repair with the addition of 1.0 wt.-% nano-Al2O3 resulted in metallurgical bonding at the interface and fine columnar crystal in the repair layer. The addition of nano-Al2O3 increases sites of heterogeneous nucleation, which acts as a fine-grain strengthener. In addition, the uniform distribution of nano-Al2O3 plays a role in dispersion strengthening, resulting in improved fracture performance by approximately 10 % to 30 % as applied loads varied from 1 to 20 kN. However, the excessive addition of nano-Al2O3 gives rise to the agglomeration and micro-cracks in the repair layers and clear detachment are observed at the interface.

AbstractThe scarcity of fossil fuels may lead to a depletion of coal, oil and natural gas in the near future. Alternative fuels, especially biofuels, are receiving considerable attention for their environmental benefits. Biodiesel is a renewable and clean burning fuel that is made from waste vegetable oils, animal fats, or recycled restaurant grease for use in diesel vehicles. Biodiesel produces fewer toxic pollutants and greenhouse gases than petroleum diesel. Many biofuels have been extracted and synthesized but little has been undertaken to study their effects on corrosion. The present investigation aims to evaluate the wet corrosion behavior of copper in used groundnut oil (UGNO) as a biofuel. The varieties of its blending ratios with commercial diesel (5, 10 and 20 %) were studied in accord with the mass loss method for a period of 100 h. The corrosion rate of the metal was evaluated according to mass loss and electrochemical methods. The corrosivity and conductivity of the test media were positively correlated. Wettability studies also supported the non-corrosive nature of biodiesel.
Mechanical properties of waste mussel shell particles reinforced epoxy composites
Authors: Koçhan Cemal 
Published: February 2019

Abstract
The aim of this research is to investigate the mechanical properties of a new bio-filler particle reinforced composite reinforced by recycled waste mussel shells. To this purpose, waste mussel shells were collected from a mussel trader and recycled in two stages: coarse processing using a hammer and fine processing by means of a rod mill. A size distribution analysis was conducted for the mussel shell particles after the recycling process. According to the results of the analysis, the particles were 74 μm in mean diameter with a 60 μm standard deviation. Vacuum assisted resin infusion molding, which is generally used to produce fiber reinforced composites, was used as the method of production. Subsequently, test specimens were prepared according to related standards and the mechanical properties of the composites such as micro-hardness, tensile strength, compression strength and flexural strength were investigated experimentally. Thetests were repeated five times for each mechanical property. It was determined from these experiments, that recycled mussel shell particle reinforced epoxy composites have a micro-hardness of approximately 170 HV, 24 MPa ultimate tensile strength, 112.8 MPa ultimate compression strength and 75 MPa flexural strength. Furthermore, flexural modules of the composites were calculated at 36.72 GPa. All experimental results are presented in graphs and tables. Finally, the results determined for these new bio-filler reinforced composites were compared with results pertaining to other alternative fillers available in the literature.
