Identifying the contradictions between teaching and learning processes with output standard requirements on some universities in Vietnam on the current

Regulations on output standards for graduates of majors and specialized regular full-time university-level training at universities is the system of criteria and regulations for students (both qualitative and quantitative) which universities construction, aiming to train human resources with university degrees in each industry, specialized to meet social needs. In order to meet these requirements, many universities are now actively innovating methods, applying various forms of teaching and learning to equip students with the knowledge and necessary skills, immediately meet the requirements of the job after graduation. However, reality, it is not always and were between the teaching and learning process with the expectation of the school achieving compatibility, meeting the announced output standards. On the basis of surveying the teaching and learning process at some universities in Vietnam, get feedback with employers, compare with the standard output requirements that universities have publicly announced on the mass media, the authors point out the fundamental contradictions, thereby proposing solutions to help the teaching and learning process comes in more substantially, meet the output standards announced by universities, more important is to meet the increasingly demanding requirements of the labor market.

Food insecurity and coping strategies of farm families in the Savelugu-Nanton Municipal of Northern region

The study aimed at examining the food insecurity trends and coping strategy of households in the Savelugu-Nanton Municipality of the northern region of Ghana. The study adopted a cross-sectional survey. The samples size was 300 household heads who responded to a semi-structured interview guide. Data were collected on the bio-characteristics of the household head, farm characteristics such as farm size, labor, crops grown, harvesting, consumption, ad infinitum. Other areas of data collection cover the duration of food storage. The Statistical Package for Social Sciences was used to analyze the data. Bivariate test, frequency, and percentage were estimated from the data collected. The findings of the study show that there is a rise in food insecurity from April to June among the majority of households between 2013 and 2016 farming season leading to a reduction in food consumption (80%) and increase in rural-urban migration (91%). It is recommended that the Government of Ghana should tackle the menace of climate change through policy formulation and make the provision of dugout or dams available to communities to engage in all year-round agricultural activities.

Analysis of heat dissipation in processor chipset with minichannel heat sink using nanofluids as cooling medium – A CFD approach

Due to the reduction in the size of the electronic components, heat dissipation has become a major problem. In many cases, air cooling has failed to provide the required demands. The invention of nanofluid has promised to increase the efficiency of the liquid cooling system. The addition of solid nanoparticles to the liquid actually increases the thermal conductivity of the liquid because of the higher thermal conductivity of the solid particles. In this work, the thermal performance of a minichannel heat sink was analyzed using CFD for cooling of processor chipset using nanofluids instead of pure water. The effect of different mass flow rates and various volume concentrations of nanoparticles on the overall thermal performance are also analyzed. The Alumina and graphene water nanofluids are used as coolants with volume concentrations of 0.1, 0.15 and 0.2%. The cooling fluid is made to flow through an Aluminium mini channel with height 5mm and width 1mm respectively. The maximum allowable temperature that has to be maintained at the chip is below 50oC. By using the liquid cooling system with a heat sink, this temperature is reduced as low as 41.22oC. There is also an enhancement of the convective heat transfer coefficient in using graphene nanofluids when compared to alumina nanofluids. The thermal resistance of the heat sink with nanofluids is lesser than pure water.

MRI imaging signs of Multiple System Atrophy ( MSA-C)

Multiple Systems Atrophy (MSA) is a neurologic disorder clinically characterized by parkinsonism, cerebellar ataxia, and autonomic failure. This disorder was previously known as “striatonigral degeneration sporadic olivopontocerebellar atrophy and “Shy-Drager syndrome Presence of neurogenic bladder is a characteristic feature of MSA. It is regarded as a sporadic disease with a prevalence of 4 per 1,00,000. Typically the symptoms begin between 40 and 60 years of age. It has two phenotypes: parkinsonian (MSA-P) and cerebellar (MSA-C). MRI brain acts as a diagnostic tool for MSA with the characteristic feature of “Hot cross bun' sign, seen as cruciform hyperintensity at the level of the pons in axial T2-weighted images in patients with MSA-C. We report here a case of a 55-year-old female patient who presented with complaint of gait instability, intention tremor, and orthostatic dizziness for the last 1 year. She also developed urinary incontinence from last 4 months

Comparison of three dimensional and two dimensional analyses of facial motion

The purpose of this study was to compare the amplitude of facial motion obtained using three-dimensional (3-D) and two-dimensional (2-D) methods. The amplitude of motion of fifteen facial landmarks during five maximal animations (smile, lip-purse, grimace, eye closure, and cheek-puff) was quantified in 3-D and 2-D using a video-based system. Results showed that the 3-D amplitudes were significantly larger than the 2-D amplitudes, especially for landmarks on the lower face during the smile animation. In the latter instance, the 2-D amplitudes underestimated the 3-D amplitudes by as much as 43%. The difference between 3-D and 2-D amplitudes was greater for 2-D amplitudes obtained from one camera rather than from multiple cameras. The results suggest that a 2-D analysis may not be adequate to assess facial motion during maximal animations and that a 3-D analysis may be more appropriate for detecting clinical differences in facial function.

Synthesis and antimicrobial activity of salicylaldehyde Schiff bases from aromatic amines

A new efficient and environmentally friendly procedure for the synthesis of a series of salicylaldehyde-based Schiff bases under conventional method is described. The method is compared with the microwave irradiation method also. The present work involves condensation of salicylaldehyde with various aromatic amines in water under the conventional method. A judicious choice of the solvent and reaction conditions allowed the final products to be generated in excellent yields in a one-step procedure, whereas experiments under thermal conditions led to lower yields with tedious work-up. The conventional method gives advantages like reduction in reaction time, increase in conversion, reduced wastes, and good yields.
