Nowadays, the consideration of the environmental impact of polymer products has led to the development of new materials combining polymers and renewable resources. Among these materials, biocomposites have been extensively studied. In the current work, we focused on preparation of biocomposites based on polypropylene and Vietnamese rice husk flour having narrow size distribution (100–125 (mu)m) with the presence of maleic anhydride grafted polypropylene as a compatibilizer. Rice husk flour (RHF) is one of the main agricultural residues eliminated during rice production. The effect of rice husk flour and maleic anhydride grafted polypropylene content on properties of composites was investigated. The results showed that mechanical parameters as well as thermal stability were significantly improved at relatively high rice husk content by the addition of maleic anhydride grafted polypropylene.

It is widely argued that use of petroleum is one of the biggest contributors to environment degradation. In this study, burning of oxygenated fuel blends in diesel and gasoline engines is investigated with particular attention to emissions. The study focus was twofold; firstly, to determine the extent by which emissions of NOx, uHC and CO are increased or reduced for various loads in BMEP. And secondly to compare the emissions between the two engines. In the gasoline engine, 20% methanol was blended with 80% gasoline (M20), while a blend of 20% n-butanol and 80% diesel (B20) was considered in the diesel engine. The gasoline engine was a naturally aspirated Suzuki RS-416 1.6L engine type and the diesel engine was a 1Z type, 1.9L Turbo-Direct injection (TDI). Results showed that NOx emissions increased with an increasing brake mean effective pressure (BMEP) for diesel fuel (DF) but was slightly lower than the blend B20 at 50 and 75% load; whereas using M20, NOx reduced in reference to gasoline fuel (GF) but was four times higher than that obtained in diesel engine. Firing B20 diminished the quality of unburned hydrocarbons (uHC) emissions in diesel engine based on the reference fuel DF. The range of emissions of uHC however was far less in the diesel engine than in the gasoline engine: 10-60 ppm and 600 to 700 ppm respectively. M20 reduced uHc concentration more than the GF above 25% BMEP. The concentration of carbon monoxide (CO) increased more for M20 than GF. Similarly, emission concentration of CO in B20 increased relative to DF. Exhaust gases temperature (EGT) was lower for all oxygenated blends, M20 and B20, than for GF and DF.

A simple, sensitive and accurate RP-HPLC method for the simultaneous quantification of ambroxol, roxithromycin and serratiopeptidase in bulk and combined tablet dosage form was developed and validated. Ambroxol, roxithromycin and serratiopeptidase were separated and estimated using Waters HPLC system and YMC Pack pro C18 (250 × 4.6 mm, 5 (mu)m particle size) column. The mobile phase consisted of 0.1% orthophosphoric acid and acetonitrile (60:40 v/v). The calibration curves were linear over concentration range of 12-36 (mu)g/mL, 60-180 (mu)g/mL and 6-18 (mu)g/mL with limits of detection of 0.040 (mu)g/mL, 1.176 (mu)g/mL and 0.127 (mu)g/mL for ambroxol, roxithromycin and serratiopeptidase, respectively. For the studied drugs, recovery varied in range of 99.57% - 100.24% with relative standard deviation ranging from 0.12% to 0.36%. The developed method was validated as per the ICH guidelines. The proposed RP-HPLC method could be used for the analysis of ambroxol, roxithromycin and serratiopeptidase simultaneously in combined tablet dosage forms.

Background: Diabetes mellitus is one of the most common metabolic illnesses characterised by chronic hyperglycemia and is linked to a higher risk of microvascular complications. Serum sialic acid has been identified as a possible risk factor for Type 2 diabetes. Serum sialic acid levels in Type-2 diabetics are frequently higher than in non-diabetic individuals. Objectives: The objective of the study was to estimate the serum sialic acid in patients with Type 2 Diabetes Mellitus and non-diabetic individuals in NCR, Delhi and evaluating the levels of serum sialic acid with fasting blood glucose in patients with Type 2 Diabetes Mellitus and also in non-diabetic individuals. Materials and Methods: The study, which took place in Delhi's NCR, was a cross-sectional investigation of 70 people aged 30 to 70. There were two groups of thirty-five people with type-2 diabetes mellitus (15 men and 20 females) and thirty-five people without diabetes who served as controls (16 males and 19 females). In both groups, fasting blood glucose and serum sialic acid were determined. Results: Serum sialic acid levels were found to be higher in type 2 diabetes mellitus (76.60±7.89) compared to non-diabetics (39.66±9.55) with a statistically significant p-value of <0.001. Conclusion: According to the findings of this study, serum sialic levels were found to be higher in Type 2 diabetes patients in Delhi-NCR, indicating that these patients were at risk of developing microvascular problems. As a result, determining sialic acid levels may aid in the early detection and prevention of microvascular problems associated with type 2 diabetes.

Objectives: Vein thrombosis is a major public health issue that has a significant human and economic toll on the country. Venous thrombosis is a major cause of morbidity and mortality in hospitalised patients, and it is potentially preventable. Deep vein thrombosis (DVT) has become a more well-known and potentially preventable cause of morbidity and mortality in hospitalised patients over the last decade. The goal of this study was to look at inflammatory markers in venous thrombosis. Materials and Methods: A cross-sectional study of patients admitted to tertiary hospitals was done. The research looked at 59 occurrences of venous thrombosis that had been confirmed by radiography. For involvement in the study and the conduct of investigations, written informed consent was obtained. The research was carried out between November 2017 and September 2019. Results: The study group's average age was 43.6 years (SD=16.4), with a range of 20 to 72 years. There were 48 males (81.4%) and 11 females among the 59 patients (18.6 percent). The mean Body mass index of the patients was 24.33 ± 2.84 kg/m2. Among 59 patients, 48 patients (81.3%) had elevated CRP. 46 patients (77%) had elevated Serum Homocysteine levels (>15 (mu)mol/L). 74.6 percent of the 59 participants had low HDL, 61 percent had high LDL, and 45 percent had high Triglycerides. The total cholesterol level had increased by 40.7 percent. D dimer levels were elevated in 98. 3%. Conclusion: We find that unprovoked venous thrombosis is a common concern among individuals aged 20 to 29, who are male and have a BMI of more than 25 kg/m2. Inflammatory markers were found to be considerably higher in patients with venous thrombosis.

In this work, heavy metals (Pb, Cr, Co, and Fe) were removed from polluted water using a chemical technique involving the addition of a biological polymer (alginic acid). For each element, different concentrations (0.5,1,1.50,2 ppm) were present. Within 72 hours, the pH 5 and duration of the test were evaluated, and the remaining amounts of the stated elements were detected by measuring the absorbance using the atomic absorption spectrometry technique. The results revealed that the extraction of the examined components was acidic. The greatest lead concentration was 2ppm, followed by 1.5 ppm of chromium, 0.5 ppm of iron, and 0.5 ppm of cobalt. Finally, we encourage researchers to do research on alginic acid for its easy availability and preparation.

The variations in the lactic acid content of developing eggs were examined in day to day developmental period, and significant modifications and beneficial responses to light induction were discovered when compared to the untreated control. The importance of lactic acid deposition during embryonic development under anaerobic settings is an adaptive strategy to tide over the unfavourable environmental condition. The current research project is devoted to the concept of photoperiodic effects on the lactic acid level in the developing embryo of the silkworm. During the imposed photoperiodic regimes, the lactic acid content slowly disintegrated and activated aerobic respiration in the silkworm eggs, which proliferated and facilitated the rate of increased morphogenesis and organ differential attributed to embryonic age advancement. It plays a significant role in the adaptive mechanism under extreme environmental conditions in hibernated eggs rather than non-hibernated eggs of the mulberry silkworm, Bombyx mori L. The study of the objective is to study the changes in the lactic acid content of developing embryos of CSR4 breed under 16:08 light and dark conditions.
在每天的发育期间，研究了发育蛋乳酸含量的变化，与未处理的对照相比，发现了显著的变化和对光诱导的有益反应。在厌氧环境下，乳酸沉积在胚胎发育过程中的重要性是一种适应策略，以克服不利的环境条件。目前的研究项目致力于光周期效应对蚕胚胎发育中乳酸水平的影响。在施加的光周期机制下，乳酸含量在蚕卵中缓慢分解并激活有氧呼吸，从而增殖并促进了由于胚胎年龄增长而增加的形态发生和器官差异的速度。它在桑蚕(Bombyx mori L.)的冬眠卵而非非冬眠卵在极端环境条件下的适应机制中起着重要作用。本研究的目的是研究CSR4品种发育胚胎在16:08光照和黑暗条件下乳酸含量的变化。
