DOMESTIC VIOLENCE AGAINST WOMEN IN NIGERIA: A PHILOSOPHICAL STUDY
Authors: O. Abakare Chris 
Published: May 2021

Family, apart from providing security and emotional support should provide the most secure environment for an individual to grow. However, domestic violence is largely evident in the Nigeria families and societies. Although, women are worshipped as deities at home in some cultures in Nigeria, they are also treated as second class members of the family. This is largely due to the patriarchal nature of the Nigerian society. The essence of this work is to investigate domestic violence against woman in Nigeria. This work discovers that the lack of physical power leads to general timidity in women. This work discovers that domestic violence is perpetrated by family members against women in the family, ranging from single assault to aggravated physical battery, threats, intimation, coercion, stalking, humiliating verbal use, forcible or unlawful entry, sexual violence, marital rape, dowry and even female genital mutilation. This work is of the opinion that domestic violence bluntly trips women of their most basic human rights, the right to safety in their homes and community and should be discourage.Family, apart from providing security and emotional support should provide the most secure environment for an individual to grow.

Published: May 2021

Objective: Oral isotretinoin is the most effective agent in the treatment of acne vulgaris. The risk of pigmentation due to the systemic isotretinoin may be associated with decrease in serum levels of Vit B12. The study aims to contribute to the literature by defining the association between the increase in pigmentation caused by oral isotretinoin [O-ISO] use and low vitamin B12 level [vit-B12].
Methods: In our study we evaluated 144 patients, who have facial acnes at medium degree according to FDA Acne Score and take O-ISO treatment with the dose 0.5 mg/ kg/ day for six months. The relationship of the vitamin B12 levels of the patients at the admission and 6th month and the existence of pigmentation at 6th month, the skin type and the skin layer at which the pigmentation occurs, was evaluated.Association of vit-B12 level on admission and six months post drug use with the presence of pigmentation at six months, the type of skin and the skin layer in which pigmentation occurs were evaluated.
Results: In the group with pigmentation, the mean vit-B12 level after six months of drug use was statistically lower than the mean vit-B12 level on admission [p <0.001]. In patients with no pigmentation, difference between the mean levels of Vit-B12 levels was not statistically significant [p = 0,255].
Conclusion: As a result, it was determined that the mean vit-B12 level decreased due to O-ISO use and the association of hyperpigmentation and low vit-B12 level was statistically significant. Vit -B12 monitoring and supplementation, if necessary, can help us prevent hyperpigmentation that may occur during the treatment.

<p>En 1960 y 1970, en el contexto de las teorías de la liberación y el pensamiento crítico latinoamericano, surgen diversas propuestas de hacer ciencia y construir conocimiento, alternativas a las formas hegemónicas, que se fueron consolidando como una contracorriente a las explicaciones dominantes de los procesos económicos y sociales. Bajo el lema acuñado por Fals Borda: “O ciencia rebelde, nueva, constructiva, o ciencia de segunda clase, imitativa y desadaptada”, lxs investigadorxs comprometidxs con el cambio social buscaron producir conocimiento práctico y socialmente útil, al margen de los temas impuestos por las agencias de ciencia y tecnología. Se planteó un acercamiento a la cultura y los conocimientos populares y se incorporó a lxs actorxs sociales como co-responsables de los procesos de investigación. El efecto que se quería producir era la toma de conciencia y la reflexión crítica sobre las relaciones de dominación y dependencia que involucraban tanto a lxs actorxs sociales como a lxs académicxs. </p>

Published: May 2021

Abstract
When buildings are subjected to earthquakes, dampers are effective in decreasing their failure by absorbing the input energy. An object of this study is to develop a new type of friction damper, on whose faying surface aluminium is sprayed, and the double friction joint is tightened with a high-strength bolt. When slip occurs on this friction damper, the slip coefficient is high and comparatively stable. Specimens of the friction damper were tested under the dynamic repeated loading condition to investigate the effect of the condition of the faying surface on the dynamic hysteresis characteristics. The parameters of the test are the type of sprayed metal, the sprayed side of the plate(s), thickness of sprayed metal, the finish of the sprayed surface, and initial clamping force (contact pressure). Results indicate that there exists the condition of suitable characteristics of a metal sprayed friction damper.
Applying Traction Coating to Steel Mill Rolls
Authors: Mayor V.C. 
Published: May 2021

Abstract
This paper deals with the problem of feeding hot billets into roll stands for rolling into different shapes and the need to apply a traction coating to the roll surface at the passes so that the rolls grip the hot billet. Steel mills have tried different methods over the years to make the roll surface at the passes rough, from throwing a shovelful of sand as the billet is entering the pass to knurling and embossing a rough pattern on the passes with a pepper chisel. Some mills have tried to use sand blasting on the rolls as the billet is passing through and thus ruining the bearings. The process used for this paper is spraying a 0.006" to 0.008" thick coating on the passes with Bondrite, an 80-20 Nickel Aluminum composite wire manufactured by us. The application of this coating is extremely easy and fast. The only preparation before spraying is to clean the roll surface with a good solvent that does not leave any residue. Bondrite has a very high bondstrength and bonds to the clean smooth surface of the rolls with enough bondstrength to impart a rough traction coating on the passes.
Influence of Ceramic Content and Additives on the Abrasion Resistance of Arc Sprayed Stainless Steel-TiB2 Coatings
Authors: Dallaire S. , Levert H. 
Published: May 2021

Abstract
Arc sprayed coatings are attractive means to protect components from abrasion wear provided they contain enough hard phases. Because of their hardness and toughness 316LTiB2 cermets were selected as the basis for developing wear resistant coatings. Core wires composed of 304 stainless steel sheaths filled with 10 to 65 wt % TiB2, 1 to 15 wt % additives and remaining 316L stainless steel were fabricated and arc sprayed with air. The arc sprayed stainless steel-TiB2 coatings were submitted to the ASTM G65-B abrasion test and the volume loss was measured with an optical profilometer. As expected, the volume loss decreases and the proportion of TiB2 increases. However, large differences in volume loss between coatings that contain about the same volumetric proportion of hard phases cannot be explained by a linear reationship. The inverse rule of mixing was proposed. This inverse rule of mixing was found particularly useful for determining the influence of additives. Tin, added in the core as a fugitive liquid transfer agent, was found to improve the wear resistance of coatings. These advanced arc sprayed stainless steel-TiB2 coatings can be favorably compared with coatings obtained by arc spraying commercially available solid and core wires.
Chromium Carbide Coatings Produced with Various HVOF Spray Systems

Published: May 2021

Abstract
High velocity oxy-fuel (HVOF) experiments were carried out with Diamond Jet (DJ) 2600 and 2700, P-5000, Jet Kote and Top Gun to investigate the influence of the spray system and of the spray parameters on microstructure and properties of Cr3C2-NiCr coatings. The results show that with all applied HVOF systems Cr3C2-NiCr coatings of high density, high bond strength and high wear resistance can be produced. However, microstructure and properties of the coatings mainly depend on the degree of oxidation and carbon loss of the material during the spray process. Due to the relatively low heating of the spray material the decarburization of CrsCa-NiCr was found to be very low using the HVOF systems DJ 2600, DJ 2700 and JP-5000. Additionally favored by the increased particle velocities coatings sprayed with the Diamond Jet systems and the JP- 5000 exceed coatings produced with the traditional HVOF systems with regard to hardness, wear resistance and bond strength.

Published: May 2021

Abstract
Experimental studies of the subsonic combustion process have been conducted in order to determine the quality and economics of polyester, epoxy, urethane, and hybrid polyester-epoxy coatings. Thermally sprayed polymer coatings are of interest to several industries for anti-corrosion applications, including the infrastructural, chemical, automotive, and aircraft industries. Classical experiments were conducted, from which a substantial range of thermal processing conditions and their effect on the resultant coating were obtained. The coatings were characterized and evaluated by a number of techniques, including Knoop microhardness tests, optical metallography, image analysis, and bond strength. Characterization of the coatings yielded thickness, bond strength, hardness, and porosity.
Adhesion of Thermal Barrier Coating Systems and Incorporation of an Oxidation Barrier Layer
Authors: Tsui Y.C. , Clyne T.W. 
Published: May 2021

Abstract
The adhesion of various interfaces in thermal barrier coating systems strongly affects their stability and thermal cycling life. A new spontaneous debonding technique and the four point bend delamination test have been applied to measure the interfacial fracture toughnesses of various interfaces in several thermal barrier coating systems. The spontaneous debonding technique is based on spraying a relatively stiff layer on top of the ZrO2 coating. This raises the strain energy release rate for debonding, the magnitude of which is monitored via modelling of the stress distribution. The critical strain energy release rate for debonding (interfacial fracture energy) was then determined from the stress states before and after debonding. Thermal barrier coatings (TBCs), consisting of a Ni-22wt.%Cr-10wt.%Al-lwt.%Y bond coat and a ZrO2-8%Y2O3 top coat, were deposited on a nickelbased superalloy. Two methods, air (APS) and vacuum (VPS) plasma spraying, were used to produce the bond and the top coats. The corresponding as-sprayed residual stress distributions and the interfacial fracture energies were evaluated. It was found that a VPS bond coat and an APS top coat produced the most mechanically stable structure. A layer of vacuum plasma sprayed AI2O3 was then introduced between the top and the bond coat, designed to act as an oxygen diffusion barrier. The effect on residual stress distributions, and associated crack driving forces for debonding, at different interfaces were determined. The effect of the alumina layer on the oxidation behaviour was also studied. It is shown that the oxidation barrier could significantly enhance the coating life-time.

Published: May 2021

Abstract
For reasons of the decrease in weight in the industry light cage design materials like aluminum alloys are frequently used. Because the wear resistance of aluminum alloys and/or aluminum generally is not sufficient, an increased wear resistance can be reached by means of particle reinforced aluminum coatings. The installation of ceramic reinforcing components (for example oxide particles) in the ductile metal matrix brings an essential improvement of the wear resistance particularly with regard to abrasion and short time fatigue wear. The results presented in the paper refer to research works concerning thermally sprayed Al - coatings with Al2O3- and SiC - particles as reinforcement components by vacuum plasma spraying.
Investigations on Thermal Sprayed Carbon-Short-Fiber-Reinforced Aluminum Composites
Authors: Wielage B. , Fleisher K. , Zimmerman G. 
Published: May 2021

Abstract
Composite coatings are increasingly applied for the protection against wear in mechanical constructions. Especially, in the case of abrasion these coatings offer the possibility to protect the base material. The matrix is ductile and the reinforcements cause the higher strength and hardness. A research project presented in this paper dealt with the manufacture of carbon-short-fibre-reinforced aluminum composite coatings by vacuum plasma spraying. The basis of the processing is the agglomeration of aluminum powder and carbon fibres. During the spraying process the aluminum melts, covers the fibres, and so, contributes to the creation of the composite coating and/or the composites. The processing times are so short that the damaging formation of carbides can be suppressed mostly. For the creation of free standing bodies it is necessary to find a qualified core material which allows the removing of the sprayed composites. The investigations on the composites are focused on the metallographical judgement regarding the fibre and void content, the fibre distribution, the characterization of the interface as well as the determination of mechanical properties and the wear resistance.
High Velocity Oxy-Fuel Flame Spraying-Process and Coating Characteristics
Authors: Kreye H. , Schwetzke R. , Zimmermann S. 
Published: May 2021

Abstract
High velocity oxy-fuel (HVOF) spray experiments were carried out using various spray systems. A comparison is made of the systems introduced as a first and second generation (Jet Kote, Diamond Jet, Top Gun, CDS) with the more recently introduced systems of the third generation (JP 5000, DJ 2600, DJ 2700). The comparison is based on particle velocities and experiments to evaluate the heat transfer to the particles. The results show that the systems of the new generation with a converging-diverging nozzle section can produce up to 50% higher particle velocities. The higher kinetic energy allows to reduce the thermal energy and to reduce thermally activated phase transformations of the coating material during the spray process. Carbide coatings produced with one of the new HVOF systems exhibit a higher density, higher bond strength and higher hardness as compared to coatings produced with one of the systems of the first and second HVOF generation. Furthermore, the reduced thermal energy yields less oxidative loss of carbon and opens the possibility to spray coatings with neutral or compressive internal stresses, a prerequisite to produce carbide coatings up to a thickness of several millimeters.
Effect of Grinding Mechanisms on Surface Finish and Hardness of Thermally Sprayed WC-Co
Authors: Ibrahim A. , Sampath S. 
Published: May 2021

Abstract
During grinding of thermally sprayed WC-Co, the grinding ratio G ( ratio of volume of work removed to the volume of wheel consumed) is usually low and the finish produced sometimes is inadequate. Improvement in surface finish accompanies increase in grinding ratio. The objective of this investigation is to study the effect of type of abrasive, table speed, and depth of cut on the surface finish and hardness of WC-Co. Thermally sprayed WC-12 wt % Co and WC-17 wt % Co produced using the high velocity oxygen fuel (HVOF) process, have been ground using silicon carbide and diamond wheels under different operating conditions. The surface profile reveals the significant role played by the above parameters on the surface finish. The grinding ratio, G in case of diamond grinding was found to be larger than silicon carbide grinding however, the quality of the surface finish produced by silicon carbide was better than the diamond. The surface structure of the ground WC-Co was examined by SEM. Surfaces ground using a silicon carbide wheel exhibited extensive plastic flow, while surfaces ground with diamond wheels are highly fractured with localized flow which suggests two different mechanisms of material removal. The surface hardness after grinding, was found to depend on the type of abrasive and table speed. Silicon carbide grinding has shown higher hardness and better surface finish than diamond grinding.
