Abstract:
The technological needs to achieve CO2 neutrality during glass manufacturing have been investigated by theoretical calculations on energy balances and experimental investigations on batch reactivity and fining efficiency. The concept is based on the assumption of utilization of woody bio fuel combustion directly over the batch blanket and glass melt bath for heating the glass furnace. Energy balance calculations were made for a “hot top”, 50 tonnes per day continuous furnace. Furthermore, elimination of the chemically bound CO2 in the glass batch has been considered by investigating the possib

This paper gives an attempt in determining an appropriate production batch size by using simulation method. The case study of this paper is an industry producing hard disk drives in Thailand. The scope of the production process considered in this paper is in the backend area of the production process of hard disk drives. Three main customers are considered. Each customer requires different sample size in an inspection process and the sample size affects bath size. Therefore, this paper needs to consider each customer separately and tries to determine an appropriate batch size for each customer

Abstract:
In the conventional soda-lime glass production, loose raw materials are normally mixed into a glass batch for melting. Dusting and segregation of the loose glass batch are always occurred during the melting process inside the glass furnace. Also, the loose glass batch has low thermal conductivity which limits the glass melting ability and pulling rate of the glass furnace. Granulation and preheating of glass raw materials have been proposed to solve the problems. In this study, the granulated soda-lime glass batch (SiO2 50% Na2CO3 22.5% CaCO3 12% NaAlSi3O8 9.5% BaCO3 2.5% ZnO 1.75% Sb2O3 1% an

Abstract:
Background: Competency-based medical education (CBME) has transformed the MBBS curriculum and aims to emphasize the five roles of an Indian medical graduates: clinician, leader, communicator, life-long learner, and professional. Accordingly, various changes have been made in the curriculum and assessment of Phase II students in pharmacology since 2019. The scores in the theory component have changed from 110 to 200, and those in the practical component have changed from 40 to 100. Aims and Objectives: To assess performance of students in the theory and practical components of the final summati

The study examines the effect of temperature fluctuations on biogas production efficiency in biogas plants with the aim of evaluating the temperature flexibility of the process. Laboratory scale batch reactors were prepared with the chosen substrate (Dried Distillers Grains with Soluble, DDDS) and the study was conducted in three batches. A biogas formation potential test was implemented in each batch in a temperature-controlled room and in a temperature controlled water bath. The temperature changes took place on the third day of tests to evaluate the effect of 5°C, 10°C and 15°C increases on

Abstract:
Succinic acid (SA) is one of the most prominent C4 biomass-based platform chemicals that can be biologically obtained. This article verifies, for the first time, the possibility of producing succinic acid with fed-batch or repeated batch operations with Actinobacillus succinogenes in a resting state, that is, in the absence of a nitrogen source. In this work it is possible to optimise separately the stages of cell growth and production in the fed-batch or repeated batch modes, minimising the costs associated with the nitrogen source and facilitating the subsequent purification of SA.

Abstract:
Abstract To meet assembly requirements, carbon fiber reinforced plastics (CFRP) generally require mechanical processing, of which the most common form is drilling. As a result of the increasing quantity of use and growing structural complexity of CFRP, the demand for batch high-precision hole making is becoming increasingly urgent. However, existing research is mostly focused on the small-batch and small-thickness drilling of samples. With a customized PCD drill bit, this study investigates the effects of large-batch drilling on the failure forms of the drill bit and the quality of holes drill

Abstract:
Nitrate pollution of ground water is increasing alarmingly in various countries. Biological denitrification has been found as the most inexpensive and effective technique for nitrate removal. The present work involves batch studies for heterotrophic biological denitrification using cotton as the carbon source and Pseudomonas fluorescens NCIM 5059 and Pseudomonas stutzeri NCIM 5136 as the microbial strains. A maximum removal of 91.0 mg/l at 30°C for the strain Pseudomonas fluorescens and 89.2 mg/l at 40°C for the strain Pseudomonas stutzeri was observed for an initial nitrate concentration of 1
