Finite Element Investigation of Moment Effect on Fretting Fatigue

/in /by

Fretting fatigue is a degrading process which is responsible for considerable amount of mechanical structure failure every year. In the present study, a finite element model is proposed to show the effect of a bending moment on a flat surface under fretting loading. The results show that the bending moment has a major effect on the friction stress distribution on the surface of the two solids under contact. Finite element analysis predicts an increased damage effect on the surface of solids when a load is applied as a pure moment. The results predict elevation in the relative slip between the surfaces after applying the bending moment.

Preparation and Characterization of Zinc Oxide (Zno)/Polymethyl Methacrylate (PMMA) Nanocomposites

/in /by

A series of novel zinc oxide / Poly (methyl methacrylate) nanocomposite films with different ZnO contents were prepared through inclusion of pre-synthesized zinc oxide nanoparticles. The physical composition and morphology of the as-prepared nanocomposites were studied by XRD and TEM. The TEM analyses revealed that the zinc oxide nanoparticles have a particle size of ~3–5 nm. X-ray diffraction proved the presence of the amorphous PMMA in the nanocomposites. The intermolecular interactions within the polymer nanocomposites were explored by FTIR and XRD. FTIR spectra confirmed the dispersion of the zinc oxide nanoparticles in the Poly (methyl methacrylate) i.e. PMMA matrices. The UV-Vis absorption measurements of the ZnO/PMMA nanocomposites proved their potential optical properties.

Association of Colours and Mood Tones That Could Define Stress among International School Students in Bangkok

/in /by

Have you ever wondered how colours perceiving through the lens of our eyes influence our emotions or why some objects in different colours dissimilarly affect the mood we experience in our daily lives? The purpose of this study is to determine the correlation between colours and stress levels of international school teenagers. The rationale behind this topic is from theGoethe’s Theory of Colours. To test whether two variables correlate, we conducted a cross-sectional survey study. Our questionnaire contains 28 questions, all of which have been approved by 4 experts. Data were collected from Mahidol University International Demonstration School (MUIDS) students who aged between 15 and 18 years old using an online survey, Google Forms.  A total of 245 students participated in the study and completed the survey. To determine the correlation between colours and stress levels, we used Statistical Product and Service Solutions version 27.0 (SPSS) for data analysis. Pearson’s correlation test revealed that there is no significant correlation between colours and stress levels. Although we did not find any correlation, we suspected that there might be other possible factors such as cultures, personality and situational factors that play a significant role in developing stress. Moreover, colours also have different meanings in different cultures. Therefore, more scientific research is required to gain a better understanding of colour psychology.

Pandemic and the Predicament of Labour Migration: The Indian Experience of Mitigating the Multifaceted Dimensions of a Humanitarian Catastrophe

/in /by

The COVID-19 Pandemic has accentuated pre-existing global conflicts and fissures tremendously, and India has been plagued with multifaceted challenges from skyrocketing unemployment, demand and public debt crisis to the predicament of labour migration, characterized by a plethora of economic, sociological, political and humanitarian ramifications. The rudimentary objective of this paper is to offer a normative teleological insight into the de facto migrant labour crisis in India, while holistically juxtaposing myriad ontological and epistemological indicators, with an emphasis on the economic and human rights dimension of Pandemic-induced intra-state and inter-state labour migration. While assessing a series of macro-societal and cyclical developments, ranging from “Push and Pull” factors of labour migration, reactionary decision-making of the political establishment to the repercussions of cyclical lockdowns, the attitudinal and ideational component of the social order towards migrant labourers has been highlighted, when a virulent contagion has propelled systemic racial discrimination, cognitive biases, ethnocentrism, xenophobia and institutionalized otherization vis-à-vis the instruments of statecraft, during the pyrrhic rise of mobilization on the closures of borders. While the notion of physical and social distancing is antithetical to the rationale behind society and politics as collective decision-making arenas, the current health crisis has compelled to turn the lens back on the struggles and vast array of insecurities of migration and settlement.  Additionally, this paper throws light on the immediate contours and trajectories of forced and voluntary labour migration, processes of assimilation and acculturation, how networks and kinship ties that migrant labourers bring with them shape the magnitude of internal and international migration by adding to the changing global demography. A series of speculative policy prescriptions have been suggested, advancing an ethos of care and respect.

Improving India’s Pandemic Response through a Health Information System Reform

/in /by

Despite stringent lockdown measures to curb the spread of the 2019 Coronavirus disease (COVID-19), India remains vulnerable to an uncontrolled rise in the number of cases and deaths. Furthermore, in spite of the high number of recorded cases, the actual case counts may be much higher due to poor data reporting of probable and confirmed cases of COVID-19 from all of India’s states. Being a populous country with the potential to become the world’s COVID-19 epicenter, it should be the Indian government’s top priority to strengthen India’s health information system (HIS) to support their infectious disease response.

To ensure that this paper is guided by current research on India’s HIS performance, a search strategy was developed on Ovid MEDLINE using database-specific subject headings and text words. The search terms used included: “health information systems” AND “India” AND “COVID-19” OR “Coronavirus.”

Most district level COVID-19 information management is still paper-based, and with India’s vast terrain, this approach is prone to data compilation errors. Furthermore, India’s fragmented HIS has led to ineffective collaboration between COVID-19 response agencies at the central, state, and district levels, thereby creating barriers pertaining to the compilation and coordination of COVID-19 data.

Investing in the use of technology is a viable approach to strengthen the country’s HIS performance during an infectious disease pandemic. To address the challenges associated with India’s fragmented HIS, the government is encouraged to implement a national regulatory body to monitor health information inputs and outputs.

Studies on Fish feed Formulation of Indian Major Carps from Aquatic Macrophytes, Lemna minor and Eichhornia crassipes

/in /by

In the present study, highest SGR (Specific Growth Rate) was obtained in 20% in Lemna minor and 10% in Echhornia crassipes. The leaves of aquatic plants had considerable amount of crude protein and crude lipid, which improves the growth of fingerlings of fish upto a certain levels of inclusions, thereby reducing the feed cost. The slow growth performance might be due to absence of natural feed in the laboratory culture. The leaf meals inclusion has much advantage in growth performance of fish. However these leaf meals need processing to lower their fibre content, which to be used as fish feed.

Investigating the Relationship between Unemployment and Inflation in Nigeria

/in /by

This study considered the impact of inflation on unemployment in Nigeria viz avis selected macroeconomic variables. The researcher adopted co integration, vector error correction model and VEC Granger causality test econometric procedure in the analysis of the data employed. The specific objectives of the study are; (i) to determine the extent to which inflation impact on unemployment in Nigeria within the period of study, (ii) to examine if government expenditure have any significant impact on unemployment in Nigeria within the period of study, (iii) to estimate the significant impact of foreign direct investment on unemployment in Nigeria within the period of study; (iv) to investigate the extent of direction of causality between unemployment and inflation in Nigeria within the period of study. The results of the research revealed long run relationship among estimated variables, VECM result showed a positive significant relationship between inflation and unemployment in the short run and long run, government expenditure and foreign direct investment maintained negative relationship with unemployment both in the short and long run. The VEC Granger causality test indicated causality among UNEM, INF and TGEX. The research recommended that (i) government should focus on policy and strategy that can attract foreign direct investment into the country, (ii) government should try to maintain low inflation rate through suitable monetary policy; (iii) government should encourage investment platforms and enabling environment for effective and efficient national output; and (iv) Government should consciously increase fiscal space for capital activities and projects that are capable of generating income, increase domestic and public spending, improve economic status and reduce unemployment. This paper concluded that the Philip’s curve hypothesis does not apply in Nigeria within the period of study as the result failed to establish an inverse relationship as postulated by A.W. Philips.
