Aims:
To develop an efficient protocol, which involves an exploration of the
catalytic potential of both the room temperature and surfactant ionic liquids towards the
synthesis of biologically important derivatives of 2-aminothiazole.

Objective:
Specific heat capacity data as a function of temperature for the synthesized 2-
aminothiazole derivatives has been advanced by exploring their thermal profiles.

Methods:
The thermal gravimetry analysis and differential scanning calorimetry techniques
are used systematically.

Results:
The present strategy could prove to be useful for researchers working in the field
of surfactants and surfactant-based ionic liquids towards their exploration in organic synthesis.
In addition to that, the effect of electronic parameters on the melting temperature of
the corresponding 2-aminothiazole has been demonstrated with the help of thermal analysis.
Specific heat capacity data as a function of temperature for the synthesized 2-
aminothiazole derivatives has also been reported.

Conclusion:
Melting behavior of the synthesized 2-aminothiazole derivatives is to be described
on the basis of electronic effects with the help of thermal analysis. Additionally,

thermodynamic parameters such as entropy and enthalpy.
Effect of Additives on the Electrical, Structural and Mechanical Property Modification of PEO-NH4HF2 based Polymer Electrolytes
Authors: Sharma Jitender Paul 
Published: May 2020

Objective:
Polyethylene oxide (PEO) composed of 10 wt% ammonium bifluoride
(NH4HF2) exhibited higher conductivity of 5.96x10-6 S/cm as compared to other concentrations
of salt at room temperature. The effect of additives, i.e., nano-sized fumed silica concentration
as nanofiller and propylene carbonate (PC) concentration as plasticizer on electrical, structural,
as well as mechanical property studies of polymer electrolytes has been studied.

Methods:
The ionic conductivity, as well as dielectric studies of polymer electrolytes consisting
of polyethylene oxide and different (x wt%) ammonium bifluoride (x=1, 2.5, 5, 10
and 15 wt %), have been measured using complex impedance spectroscopic technique. X-ray
diffraction (XRD) and differential scanning calorimetry/thermogravimetric analysis (DSC/
TGA) studies have been conducted to observe the effect of additives on crystalline phase,
crystallite size, melting temperature and weight loss of different polymer electrolytes. The
effect of additives on the mechanical properties (tensile strength, modulus of elasticity and %
elongation at break) of different polymer electrolytes has also been studied by Universal
Testing Machine (UTM).

Results:
The maximum conductivity achieved was 1.55× 10-4 S/cm in case of plasticized
nanocomposite polymer electrolytes with the simultaneous presence of 3 wt% fumed silica
and 0.3 ml propylene carbonate. The variation of ionic conductivity at different temperatures
and activation energy values of different polymer electrolytes were also measured and observed
in good correlation.

Conclusion:
The observed enhancement in the ionic conductivity of polymer electrolytes
with additives is due to an increase in carrier concentration, amorphous content, chain flexibility,
as well as the formation of more conducting pathways. Hence, this new approach led
to the development of plasticized nanocomposite polymer electrolytes with high ionic conductivity
and improved structural and mechanical properties.

Authors: Delgado Villanueva Alexi , Loayza Andres Aguirre 
Published: May 2020

Actualmente los parámetros de la evaluación de la calidad del aire se analizan de manera independiente; dejando lado el enfoque sistémico del ambiente, el cual establece que la calidad del aire está influenciada y controlada por muchos tipos de factores, en donde varios parámetros interactúan y se restringen mutuamente, por tal razón se propone un sistema de evaluación superior, que tome en cuenta el alto grado de incertidumbre presente en el medio, dicho sistema es la metodología de análisis de Grey Clustering cuya base es la lógica difusa. La propuesta metodológica evaluará el nivel de calidad de aire en Lima Metropolitana, mediante el método de “Triangulación del punto medio en base a funciones de Whitenización – CTWF”, en donde se demostrará que el modelo propuesto es exacto, comparable y aplicable. Los datos de calidad del aire se obtuvieron del Servicio Nacional de Meteorología e Hidrología del Perú-Senamhi. El método CTWF se aplicó utilizando los principales indicadores de la calidad del aire, tales como, PM10, PM2.5, SO2 y N02. Los datos de muestreo se clasificaron usando el Índice de Calidad del Aire Anual –YACAQI; como resultado de la evaluación de la calidad del aire se determinó que la mayoría de distritos presentaban problemas muy graves de contaminación del aire. El diagnóstico permitirá que la sociedad en general y municipalidades tengan como resultado un instrumento técnico de análisis objetivo e integral, que brinda resultados fáciles de interpretar y permita enfocar los principales contaminantes persistentes en el medio.

Background and objectives
Outcomes of kidney transplant recipients diagnosed with coronavirus disease 2019 as outpatients have not been described.

Design, setting, participants, & measurements
We obtained clinical data for 41 consecutive outpatient kidney transplant recipients with known or suspected coronavirus disease 2019. Chi-squared and Wilcoxon rank sum tests were used to compare characteristics of patients who required hospitalization versus those who did not.

Results
Of 41 patients, 22 (54%) had confirmed coronavirus disease 2019, and 19 (46%) were suspected cases. Patients most commonly reported fever (80%), cough (56%), and dyspnea (39%). At the end of follow-up, 13 patients (32%) required hospitalization a median of 8 days (range, 1–16) after symptom onset, and 23 (56%) had outpatient symptom resolution a median of 12 days (4–23) after onset. Patients who required hospitalization were more likely to have reported dyspnea (77% versus 21%, P=0.003) and had higher baseline creatinine (median, 2.0 versus 1.3 mg/dl, P=0.02), but there were no other differences between groups.

Conclusions
In an early cohort of outpatient kidney transplant recipients with known or suspected coronavirus disease 2019, many had symptomatic resolution without requiring hospitalization.

Published: May 2020

Processed fruit products commonly contain very low protein due to the heat treatment during processing period. This article presents the researchresults concerning the increase of nutrition value of papaya jam fortified with soya protein concentrate. Papaya jam prepared with ratio 40:1, 40:2, 40:3, 40:4, and 40:5 (v/v) of papaya pulp and soya protein concentrate. The treatment of papaya jam and soya protein with the highest acceptability was then analyzed for the changes in chemical constituents and overall acceptability at monthly interval during three months of storage. The parameters that being analyzed were moisture content, total soluble solids (TSS), pH, total and reducing sugars, non-enzymatic browning, acidity, ascorbic acid, total carotenoid, total phenol, crude protein, and total plate count. The results showed that fortified papaya jams prepared with papaya pulp and soy protein concentrate ratio at 40:1 had the highest acceptability. During storage time it revealed that moisture content, TSS, pH, total and reducing sugars, and non-enzymatic browning increased, while acidity, ascorbic acid, total carotenoids, phenols, total antioxidants and crude protein contents of jam decreased. Fortification of papaya jam with soya protein concentrate (40:1 v/v) increased crude protein content on average from 3.15% to 4.16%. Total plate count (TPC) indicated that no microbial contamination during 3 months storage period. It can be concluded that papaya jam fortified with soya protein concentrate remained acceptable during storage although the acceptability decreased over time.

Published: May 2020

Over one billion tires are disposed into the environment each year and this has become a major environmental issue in the globe. Recycling of these waste tire rubbers in concrete has gained attention from researchers all around the world. In this study, the impact resistance of rubberized concrete exposed to fire is investigated experimentally in the laboratory. For that purpose, sixty specimens were made with five different mixes replacing their sand content partially with different percentages of tire rubber by weight ratios of 0% control, 6%, 12%, 18% and 24%. The water/cement ratio was kept constant at 0.393 in all the mixes. In each mix, fifteen concrete specimens with the size of (150 x 150 x 73) mm were prepared to expose to fire. Every three specimens were gradually exposed to fire for four various durations of (0, 15, 30, and 45) minutes. Each specimen was then tested in a drop-weight impact machine by dropping 2240-gr and 4500-gr hammers from heights of 280 mm and 450 mm. The average impact energy of three identical specimens required for the occurrence of the final fracture was calculated. The investigational results are compared with results of control samples. It is found that the impact energy considerably increased with an increase of the rubber replacement. It is, also, noted that any increase in the burning period of specimens results in a reduction of the impact energy and more early crushing of the rubberized concrete.

An example is applied to illustrate the proposed technical accuracy. Also, a comparison between the obtained results is made, in addition to the application of the crisp solution, when theï€ ï¡-level equals one.
Vestibular stimulation induced alteration in glutamate levels improves memory and anxiety scores in scopolamine induced dementia rats
Authors: K V Jinu , R Archana , J K Mukkadan 
Published: May 2020

Glutamate is an excitatory neurotransmitter which is essential for cognition but, at the same time, a neurotoxin if accumulated beyond a certain level. The derangement of glutamate level in brain is closely associated with Alzheimer’s disease. Vestibular stimulation is known to stabilize various neuro-chemical transmission in central nervous system, especially effective in enhancing acetyl choline level and reduction of acetyl cholinesterase level. So the current study has undertaken to evaluate glutamate level in dementia and vestibular stimulation groups and its role in improving memory and anxiety scores. In the present study, 32 Wistar rats were used. Scopolamine was used to induce dementia and caloric stimulation (bilateral, unilateral right and unilateral left) was used stimulate vestibular system. Behavioral parameters like water maze used to asses memory and elevated plus maze was used to assess anxiety in our study. Glutamate was quantified by spectroflurimetry and histopathology of hippocampus and cortex were assessed. Caloric vestibular stimulation effectively reduced glutamate level near to normal values and this result reflected in increased memory scores in water maze and increased exploratory activities in elevated plus maze. Especially unilateral left vestibular stimulation has found beneficial in reducing glutamate level. All these positive outcomes have proven that vestibular stimulation can increase memory and anxiety scores in dementia and thereby can be used as an alternative therapy in this field. Further animal studies and human studies are needed to dig deep into the molecular mechanisms behind its actions.
