Azo linked salicyldehyde and a new 2-hydroxy acetophenone based ligands (HL1 and HL2) with their copper(II) complexes [Cu(L1)2] (1) and [Cu(L2)2] (2) were synthesized and characterized by spectrosc...

Of concern in this paper is an investigation of the combined effects of thermal radiation and Hall current on momentum, heat and mass transfer in laminar boundary-layer flow over an inclined permeable stretching sheet with variable viscosity. The sheet is linearly stretched in the presence of an external magnetic field and the fluid motion is subjected to a uniform porous medium. The effect of internal heat generation/absorption is also taken into account. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The boundary-layer equations that governing the flow problem have reduced to a system of non-linear ordinary differential equations with a suitable similarity transformation. Then the transformed equations are solved numerically by employing a finite difference scheme. Thus the results obtained are presented graphically for the various parameters of interest.

Background: Acute appendicitis is one of the most common acute surgical condition of the abdomen and appendicular lump is formed if treatment is delayed. It is encountered in 2 – 6%of patients. The traditional treatment of appendicular lump is conservative followed by delayed appendectomy. During conservative treatment 10-20% are not resolved and lead to gangrene or perforation followed by localized abscess or generalized peritonitis requiring early surgical intervention. Aims & Objective: A comparison of early exploration versus conservative management of appendicular lump. Material and Methods: A total of 632 patients were admitted in emergency and OPD of this hospital with diagnosis of appendicular lump and acute appendicitis over a period of three years, all were included in the study. All age groups and both sexes were included. The patients were divided randomly into two groups. Group I, early surgical exploration and group II, conservative approach with OCHSNER SHERREN, REGIME followed by interval appendectomy. Results: Out of 632 patients, only 62 patients who presented with appendicular lump were reviewed, suggesting 9.81% incidence. Maximum patients were found in age group of 21–30 years. Average duration of symptoms was 4 days. Two methods were adopted for the management of appendicular lump. The first group included 31 patients who were operated immediately after investigations and second group of 31 patients were managed conservatively followed by delayed appendectomy. In the first group mean hospitalization time was 4 days. Residual abscess, adhesive intestinal obstruction, failure of treatment and readmission were not observed. In the II group mean hospitalization time 10 days, more chances of residual abscess, adhesive intestinal obstruction, failure of treatment and readmissions were noted. Conclusion: Based on our finding, it can be concluded that early surgical exploration confirms the diagnosis and cures the problem, reduce the cost of management, shortens the convalescence and hospital stay with reasonably satisfactory outcome.
