    Objective: Pseudomonas aeruginosa is the commonest agent causing opportunistic nosocomial infections, contributing to mortality and morbidity worldwide. Along with its intrinsic and acquired resistance mechanisms, infections caused by Pseudomonas species further lead to treatment failure. This study was done to determine the prevalence and antimicrobial susceptibility pattern of different species of Pseudomonas isolated from various clinical samples by phenotypic methods. Methods: This study involved the examination of clinical samples for various species of Pseudomonas by using different standard biochemical tests. Their antimicrobial susceptibility profile was performed by the Kirby Bauer disc diffusion method. Analysis of the antibiogram pattern was done to study the multi-drug resistance among Pseudomonas species. Results: Out of the 1249 bacterial isolates, Pseudomonas species accounted for 12.9%. Pseudomonas species showed maximum resistance to gentamicin (31.4%), followed by ciprofloxacin (30.2%. and showed the least resistance tocolistin and polymyxin B. 46 isolates out of the 162 (28%) were found to be Multi-Drug Resistant (MDR) Pseudomonas aeruginosa. Conclusion: The present study highlights that Pseudomonas species remains a major cause of hospital-acquired infections. Multidrug resistance was observed in most of the strains, which makes the therapeutic options more difficult. Surveillance of antimicrobial resistance and strict infection control measures are essentially to be practiced in managing and control of infections caused by Pseudomonas

The experiment was laid out in factorial randomized complete block design with three replications. The treatment consisted of six foliar dozes viz. T1 (Tap water as control), T2 (0.10 % urea), T3 (0.25 % urea), T4 (0.40 % urea), T5 (5 ppm planofix) and T6 (10 ppm planofix) and three application frequencies viz. F1 [20 days after sowing (20 DAS)], F2 (30 DAS) and F3 (20 and 30 DAS). Maximum foliage yield (6.94 t/ha) was recorded in 10 ppm planofix coupled with its twice application at 20 and 30 DAS which was closely followed the foliage yield (6.33 t/ha) by 5 ppm planofix with the same application frequency. The foliage yield was increased with the increase in urea concentration. The highest foliage yield (5.37 t/ha) was also recorded from twice application of urea and planofix at 20 and 30 DAS, respectively. Planofix 10 ppm with its twice application at 20 and 30 DAS gave the highest benefit-cost of ration 2.51.Int. J. Agril. Res. Innov. & Tech. 5 (1): 40-44, June, 201

    This paper is aimed to determine the surface water quality in an around Sylhet City. We used surface water for our keen purpose. Surface water as well as ground water has been contaminated by humans. Nowadays, water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels. In addition to the acute problems of water pollution in developing countries, developed countries continue to struggle with pollution problems as well. Discharges from various contaminated sources are a very common thing in city life which deteriorates the water quality of any main water source and necessary treatment is required to make water potable. Sylhet, one of the six divisional cities of Bangladesh is suffering from shortage of domestic water supply and adequate sewerage lines, drainage and solid waste disposal problems. This paper will focus on evaluation of the existing condition of surface water in Sylhet City and investigating some physical and chemical quality of water throughout the year 2008 to 2009. The selected parameters for assessing the water quality are pH, total dissolved solid (TDS), biochemical oxygen demand (BOD), dissolved oxygen (DO), ammonia nitrogen, nitrate and turbidity in the vicinity of Sylhet City

    Modeling and optimization of process parameters in face milling of Ti6Al4V alloy using Taguchi and grey relational analysis

    Get PDF
    Titanium alloys are extensively used in aerospace, missiles, rockets, naval ships, automotive, medical devices, and even the consumer electronics industry where a high strength to density ratio, lightweight, high corrosion resistance, and resistance to high temperatures are important. The machining of these alloys has always been challenging for manufacturers. This article investigates the combined effect of radial depth, cutting speed and feed rate on cutting forces, tool life, and surface roughness during face milling of Ti6Al4V alloy. This study focuses on the significance of radial depth of cut on cutting force, tool life and surface roughness compared to that of cutting speed and feed rate during face milling of Ti6Al4V alloy. In this paper, mono and multi-objective optimization of the response characteristics have been conducted to find out the optimal input parameters, namely, cutting speed, feed rate, and radial depth of cut. Taguchi method and analysis of variance (ANOVA) analysis have been used for mono-objective optimization, while Taguchi-based grey relational analysis has been used for multi-objective optimization. The regression analysis has been performed for developing mathematical models to predict the surface roughness, tool life, and cutting forces. According to ANOVA analysis, the most significant parameters for tool life and cutting force (FY) are cutting speed, and radial depth of cut, respectively, while feed rate is observed to be the most significant parameter for surface roughness and force (FX). The optimal combination of input parameters for tool life and FY are 50m/min cutting speed, 0.02mm/rev feed rate, and 7.5mm radial depth of cut. However, the optimal parameters for surface roughness are 65m/min cutting speed, 0.02mm/rev feed rate, and 7.5mm radial depth of cut. For FX, the optimal condition is observed as cutting speed 57.5m/min, 0.02mm/rev feed rate, and 7.5mm radial depth of cut. A validation experiment, conducted at the optimal parameters of surface roughness, shows an improvement of 31.29% compared to the surface roughness at initial condition. Taguchi-based grey relational analysis for multi-objective optimization shows an improvement of 55.81%, 6.12%, and 23.98% in tool life, surface roughness, and FY, respectively. ANOVA analysis based on grey relational grade shows that the radial depth of cut is the most significant parameter for multi-objective optimization during the face milling of Ti6Al4V

    Kearifan lokal perlu ditanamkan sejak dini untuk mendukung upaya pembentukan karakter. Nilai-nilai kearifan lokal perlu diintegrasikan dalam pembelajaran di sekolah, salah satunya melalui materi yang tersusun dalam bahan ajar. Berdasarkan hasil observasi, belum ada bahan ajar yang memuat nilai-nilai kearifan lokal, utamanya nilai-nilai kearifan lokal Kabupaten Kediri. Oleh karena itu, penulis mengembangkan sebuah bahan ajar berupa modul berbasis kearifan lokal sebagai alternatif untuk menanamkan nilai-nilai kearifan lokal melalui pembelajaran di Sekolah Dasar. Modul berbasis kearifan lokal memungkinkan siswa memperoleh pemahaman nilai-nilai kearifan lokal dalam pembelajaran sekaligus mendapat kesempatan untuk belajar secara mandiri sesuai kecepatan dan kemampuan belajarnya
