The validity of performance assessment depends to a large extent on the rating scale that is used in the assessment procedure. It delineates the theoretical construct being measured and yield considerable influence on how performances are judged and interpreted. Implications of the use of rating scales are therefore far too important to be taken li

This study investigates students’ conceptual knowledge and understanding of basic statistical concepts and compares it against statistical competence, which is associated with discrete statistical knowledge and basic interpretive skills. It also examines the correspondence between students’ perceived ability and their empirical understanding of

A panel of six monoclonal antibodies (mAbs) against the nucleocapsid (NP) protein of Newcastle disease virus (NDV) was produced by immunization of Balb/c mice with purified recombinant NP protein. Western Blot analysis showed that all the mAbs recognized linearized NP epitopes. Three different NP antigenic sites were identified using deleted trunca

Serum is a vital supplement in animal cell culture. Serum used in animal cell culture is from bovine source marketed by different companies, and somewhat expensive. The aims of this work were serum treatment and screening for the best serum concentration for Vero cell culture using STATISTICA software. The best result obtained from the software was

This study was carried out to isolate and identify the etiological agents causing suppurative corneal ulcers and to perform the antimicrobial susceptibility testing of the bacterial isolates. Samples (corneal swabs and scrapings) were collected aseptically from 56 suppurative corneal ulcer patients attending Rajshahi Medical College Hospital (RMCH)

Cell rupture is one of the earlier steps in downstream processing which are required for the recovery of biological products that are located inside cells. Cells could be disrupted either by using chemicals or mechanical method. In this study, cell rupture was carried out by mechanical force using high pressure homogenizer (HPH). The aim of this st

The phosphoprotein (P) of paramyxoviruses plays a central role in the viral genome RNA replication and transcription. In genome replication, the P binds to the unassembled nucleocapsid (NP0) and activates it to encapsidate the newly synthesized viral genomic RNA. P also plays a supplemental role in genomic RNA synthesis by binding to the ribonucleo

This study attempts to evaluate the removal of chromium from aqueous solution using chitosan as an adsorbent. The experiment was conducted by varying chitosan dosage (10-30 mg), pH (5-8), contact time (10-90 min) and agitation speed (50-250 rpm). The initial Cr concentration was fixed to 20 mg L-1. The results indicated that pH is the most signific

This research was mainly focusing on improving the purification process for recombinant nucleocapsid (NP) protein of Newcastle disease virus (NDV). In this study, several conditions of the independent variables that affect the microfiltration process such as the temperature, transmembrane pressure (TMP), and viscosity were observed. A microporous m

An overflow system for batch esterification of Crude Palm Oil (CPO) to obtain Palm Oil Biodiesel (POB) was developed using a batch reactor (shake flask). The alkali catalyst of potassium hydroxide had been used to carry the transestrication process with methanol; ultimately, 2 layers were form from the reaction-the lower layer of glycerol and the u
