Data were collected from November 2017 to October 2019. During the study period, 89 avian species were recorded that belong to 32 families under 11 orders among which 8 (8.99%) species were common winter visitors, 3 (3.37%) were common summer visitors, 8 (8.99%) were resident migratory, 1 (1.12%) were rare resident and 69 (77.53%) were resident birds. Among the birds observed in the study area during the study period the highest number of birds was found to be insectivorous (41.57%), then the carnivorous (8.99%), then omnivorous, piscivorous and picio carnivorous (7.87%), then insecto frugivorous (6.67%), then frugivorous (5.62%), then frugio graminivorous (4.49%), then nectarivorous (3.39%), then graminivorous and molluscio carnivorous (2.25%) and insecto carnivorous (1.12%). The hight avian diversity (69.662%) was observed in Mithapur which is human inhabited area with crop lands and a lot of fruit trees and the lowest (32.584%) diversity was in Shree Rampur Bill and Kastogari Bill which has large water bodies. This study will be helpful to understand the status of birds in different season in the study area.

AC has widespread applications, including the removal of different contaminants from water and wastewater, and it is also being used in capacitors, battery electrodes, catalytic supports, and gas storage materials because of its specific characteristics e.g., high surface area with electrical properties. The production of AC from naturally occurring precursors (e.g., coal, biomass, coconut shell, sugarcane bagasse, and so on) is highly interesting in terms of the material applications in chemistry; however, recently much focus has been placed on the use of agricultural wastes (e.g., rice husk) to produce AC. Rice husk (RH) is an abundant as well as cheap material which can be converted into AC for various applications. Various pollutants such as textile dyes, organic contaminants, inorganic anions, pesticides, and heavy metals can be effectively removed by RH-derived AC. In addition, RH-de...

The analysis from employing Six Sigma and DMAIC indicated that the broken stitch and open seam influenced the number of defective products. Design of experiments (DOE) and the analysis of variance (ANOVA) techniques were combined to statistically determine the correlation of the broken stitch and open seam with defects as well as to define their optimum values needed to eliminate the defects. Thus, a reduction of about 35% in the garments defect was achieved, which helped the organization studied to reduce its defects and thus improve its Sigma level from 1.7 to 3.4.

The importance and need for the research and development into medical and healthcare devices can never be overstated. In the 21st century, medical and healthcare devices play a more vital role in our lives than ever before. A wide range of materials are being used for producing numerous medical and healthcare devices for a variety of end use. In this manuscript, historical development of wound care dressings and products are reviewed. The characteristics and requirements of modern wound dressings are summarized. A core part is devoted to the description of the materials used in medical and healthcare devices. Selected synthetic polymers are listed with their applications in medical and healthcare devices. The advantages and limitations of fibres, metals, ceramics and composites are denoted. Textile structures are highlighted with their applications in medical and healthcare devices.

SFV can be zoonotically transmitted to humans who either work with or live commensally with NHP. We analyzed the blood of 45 Bangladeshi performing monkey owners (an ethnic group called the Bedey) for SFV infection. Surprisingly, a PCR assay failed to detect SFV infection in any of these participants. This is in contrast to our previously reported infection rate of about 5% among Bangladeshi villagers.

The method is based on the Yule-Walker equations and estimates the autoregressive parameters from a finite set of measured data and then the power spectrum. An inverse filtering technique is used to estimate the
