Journal of Energy and Power Engineering 2013年第7期7卷 1250-1256页

Biomass in the form of nutshell, hay of catkin, wheat straw and linseed residue in particles have been pyrolyzed in laboratory scale fixed bed reactor which yielded liquid oil, solid char and gas. The variation of oil yield for different biomass feedstock with reactor bed temperature and feed size is presented in this paper. A maximum liquid yield of 55 wt% of dry feedstock is obtained at an optimum temperature of 500℃ for a feed size of 300-600μm with a running time of 55 min for nutshell as the feedstock while the minimum liquid oil yield is found to be 30 wt% of feedstock at an optimum temperature of 400℃ for a feed size of 2.36 mm with a running time of 65 min for linseed residue as the feedstock. A comparison on the product yields is highlighted in this study. The pyrolysis liquid products are characterized and compared for some of the fuel properties like HHV （higher heating value）, viscosity, density and specific gravity.

Nanocrystalline magnesium ferrite has been prepared by chemical co-precipitation technique. Structural characterization has been performed by X-ray diffraction. Formation of ferrites has also been studied by using FTIR. Frequency dependence of real and imaginary part of initial permeability has been presented for the samples sintered at different temperatures. Real part of initial permeability, increases with the increase of grain growth. The loss component repre- sented by imaginary part of initial permeability decreases with frequency up to the measured frequency of this study of 13 mHz. Curie temperatures have been determined from the temperature dependence of permeability. Curie temperatures for the samples of this composition do not vary significantly with the variation of sintering temperatures. B-H loop measurements have been carried out by B-H loop tracer. Transport property measurements haven been carried out by electrometer and impedance analyzer.

Co-rich Nd-Fe-B nanocomposite ribbons with Tb substituted have been fabricated by single roller melt spinning technique of Nd4-xTbxFe83.5Co5Cu0.5Nb1B6 (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) alloys in an argon (Ar) atmosphere at a circumferential speed of 40 m/s. According to the differential scanning calorimeter (DSC) traces the nanocomposite samples have been annealed at different temperatures like 675°C, 687°C, 700°C, 712°C and 725°C for 10 min. Crystallization behavior was studied by X-ray diffraction in which it was found that the XRD patterns are characterized by broad diffused pattern which demonstrate the amorphous state of materials. The ribbon samples were also characterized by vibration sample magnetometer (VSm) and mössbauer spectroscopy at as-cast and annealed condition. Co-rich and Tb substitution has significantly enhanced the value of coercivity (Hc) and maximum energy product (BH)max. Highest value of Hc and (BH)max has been obtained as 2.36 kOe and 6.11 mGOe for the sample annealed at 700°C for 10 min with higher concentration of Tb. The m-H hysteresis loops show extremely soft natures which do not possess any area. We have found reduced remanent ratio (mr/ms) up to 0.49 at optimal annealing temperature 700°C. However, with the annealing of the samples in the above mentioned temperature, evolution of large coercivity was observed due to the formation of exchange couple hard and soft nanocrystal composites. We have investigated the variation of Curie temperature (Tc) with annealing temperature of the melt spun ribbon samples. mossbauer spectroscopy was carried out to study the hyperfine parameters such as hyperfine field, hyperfine field distribution for full width half maximum (FWHm) and isomer shift of Fe species of these two phases.

Background: Although the frequencies of getting drug naive type 2 diabetes patients among all the diabetic patients are very low, nowadays it claims more attention in the treatment procedures of drug naive diabetic patients. But in Bangladesh, we have very few research-oriented data regarding the demographic, clinical and biochemical characteristics of drug naive type 2 diabetes patients. The aim of this study was to determine the demographic clinical and biochemical characteristics of drug naive type 2 diabetes patients of Bangladesh. methods: This was an open label observational real-life study which was conducted in the chambers of the investigators in several places of Bangladesh as outdoor setting during the period from August 2020 to December 2020. In total, 250 patients with drug naive type 2 diabetes mellitus were enrolled as the study population. Proper written consents were taken from all the participants before starting data collection. A pre-designed questionnaire was used in patient data collection. All data were processed, analyzed and disseminated by mS Office and SPSS version as per need. Result: Two hundred and fifty (250) participants were selected as study population. The male-female ratio of the participants was 1.4:1. The highest number of participants was from 51 - 60 years’ age group (31.20%). The highest number of participants (41%) was with overweight (BmI: 25 - 30 kg/m2). majority (65%) of the patients of this study suffered from diabetes for ≤5 years. The mean (±SD) SBP of the participants was 137.25 ± 17.50 mmHg and the mean (±SD) DBP of the participants was 85.16 ± 13.39 mmHg. We found the mean (±SD) fasting blood sugar (mg/dl), post prandial blood sugar (mg/dl), total cholesterol (mg/dl), triglycerides (mg/dl), HDl-Cholesterol (mg/dl), lDl-cholesterol (mg/dl), VlDl-cholesterol (mg/dl), uric acid (mg/dl), creatinine (mg/dl), urea (mg/dl), total bilirubin (mg/dl), direct biliru
