Bangladesh is one of a number of countries trying to prevent acid violence through legislation while providing specialized care for victims, but attitudes to women need to change for there to be further progress. Patralekha Chatterjee reports. It happened twelve years ago, but Asma Akhtar still remembers the assault vividly. A spurned suitor in his late 20s sneaked into her family's mud shack i...

This study examines the relationship between chief executive officers’ (CEOs’) characteristics (e.g., tenure, experience, education, age and compensation) accounting conservatism for a sample of 672 yearly observations from both Jordanian industrial service companies listed on Amman Stock Exchange (ASE) during period 2014–2021. Using feasible generalised least squares, results show that CEOs wi...

A 60-year-old patient with a history of alcoholic cirrhosis (Child-Pugh score C), diabetes mellitus and ongoing alcohol intake presented to the emergency departed with hypoxemic dyspnoea in the presence of ascites and peripheral edema. Laboratory data indicated acute renal insufficiency with preserved natriuresis (creatinine 3.7 mg/dL, normal 0.71.2; urea 117 mg/dL, normal 10-50; 24 h urine sod...

In PLL designs, a wide loop bandwidth is often desired as it offers fast settling time, reduces on-chip loop filter area and sensitivity of the VCO to pulling. The reference spur is a major issue when the bandwidth is increased, because ripples on the VCO control line undergo less filtering by the loop filter. This paper proposes design techniques based on sub-sampling phase detection to reduce...

This paper describes design and analysis of Spur gear. In the present work, it is proposed to substitute the metallic gear of sugarcane juice machine with plastic gears to reduce the weight and noise. For the purpose of two different types of plastic materials were considered namely Nylon and Polycarbonate and their viability are checked with their counterpart metallic gear (Cast iron). Based o...

In this study, the damping mechanism at the interface of the mating spur gear teeth is investigated. The dynamic behaviour of a spur gear pair is represented by a two Degree-of-Freedom (DOF) nonlinear model with the damping provided by the instantaneous tribological behaviour of the tooth contacts. The shear stress distributions along the tooth surfaces are incorporated with the dynamic model t...
