STUDY ON ADVANCED APPLICATION OF MINT OIL

Peppermint is most popular in traditional medicines such as herbal tea and essential oil. It is a cultivated natural hybrid of Mentha aquatic L. (watermint) and Mentha spicata L. (spear mint) in many parts of the world.

It is extracted by steam distillation and shows potential actions like antioxidant, antiallergic, antimicrobial, antiviral, antimycotic, antitoxigenic, antifungal, antiparasitical, anti-inflammatory, antiseptic, insecticidal and antitumor. The unique property of mint is analgesic (pain-killing). These properties contribute to its applications and hence it is widely used in pharmaceutical, food industries, agricultural field and is also effective on gastrointestinal tissue, respiratory system, central and peripheral nervous system. This study focuses on recent advances and application of mint oil.

EFFECT OF PLANT GROWTH REGULATORS ON GERMINATION IN TWO ONION VARIETIES

An attempt has been made to study the effect of Presowing soaking treatments with GA, SA, BA and CCC on seed germination, seedling growth and vigour index of onion variety Local white and N-53. The germination percentage of onion variety Local white and N-53 was decreased in response to GA, SA and CCC, while, it is increased in response to 6BA, Methionine and Cysteine pretreatments. The root length showed slight induction in response to GA, 6BA and Methionine pretreatments. The shoot growth was stimulated in response to these chemical growth regulators in Local white variety and N-53 variety. The seedling biomass was considerably increased in N-53 and Local white onion variety due to presowing soaking treatments of GA, methionine and cysteine, while, in response to SA, 6BA, CCC pretreatments seedling biomass was slightly decreased.

CHARACTERIZATION AND PURIFICATION OF UREASE ENZYME FROM NEW PROTEUS MIRABILIS STRAIN

Proteus mirabilis bacterium is a common etiologic agent of urinary tract infections and produces large amounts of urease enzyme (EC 3.5.1.5). The urease enzyme producing new Proteus mirabilis isolate was isolated from positive sample collected from Khartoum hospital. In this study’s the enzyme was extracted from the bacterial isolate by distilled water and purified by gel-permeation. Urease enzyme activity was measured in SDS page based on cresol red and assayed spectrophotometically. The recovery percentage of pure urease enzyme was in range 55-98%. The Bacterium protein extraction retained urease enzymatic activity and showed the typical subunits of Mr 66000, 45000, 29000, and 15000 when subjected to sodium dodecyl sulfatepolyacrylamide gel electrophoresis.

A COMPARATIVE ANALYSIS OF TRIGLYCERIDES LEVEL BASED ON HIGH DENSITY LIPOPROTEIN CHOLESTEROL IN THREE DISTINCT PHASES OF BLOOD PRESSURE USING MULTIPLE LOGISTIC REGRESSION

Atheroscleorosis is a common disorder which hardens the arteries due to the exessive of plaque which are made of fat, cholesterol, calcium and other substances. This study aims to examine factors that are associated directly or indirectly with triglycerides level in the distinct phases of blood pressure. Multiple logistic regression was employed in order to assess the associated factors of triglycerides level in three distinct phases of blood pressure. The statistical analysis revealed that there are partially significant differences due to the different distinct phases of blood pressure. High density lipoprotein cholesterol, total cholesterol and proconvertin were the factors which statistically significant across three distinct phases of blood pressure. This finding shows that the triglycerides might be a valuable marker for atherosclerosis in three distinct phases of blood pressure.

WATER QUALITY ASSESSMENT OF GANGA CANAL SYSTEM

Canal system is one of major requirement of modern civilization for the sustainable utilization of water in river basins. Ganga canal is one such example of canal system created on River Ganga Basin in India; originate at Bhimgoda Barrage, Haridwar. Current study is focused on Ganga canal to assess the physico-chemical parameters during 2011 – 2012 at Haridwar (Uttarakhand) with Bhimgoda Barrage (Site 1 -Control Site) and Bahadrabad (Site 2 – sampling site). During investigation maximum Turbidity (233.8 ±104.60 JTU), Total Solids (933.00 ±216.44 mgl-1) and minimum Velocity (0.93 ±0.355 ms-1), Free CO2 (1.85 ±0.14 mgl-1) and Transparency (0.22 ±0.15 m) were recorded in monsoon season at site 2. While maximum pH (8.1 ± 0.1), Total Hardness (84.38 ±4.65 mgl-1) and Dissolved Oxygen (8.64 ± 1.02 mgl-1) were recorded in summer season at Site 2 in comparison with Site 1. The mean values of these parameters were compared with WHO and ISI standards and found significant differences (p<0.05) in the mean values of Turbidity, Total solids (TS),  pH,  Dissolved Oxygen (DO),  Free CO2 and Total Hardness (TH) with sampling Sites. The Turbidity of both the Site 1 and 2 was recorded above the permissible limit, but higher at site 2 in comparison to Site 1. The values of the studied parameters were more during rainy season and summer season at Site 2 as compared with Site 1. The results indicated that most of the physico-chemical parameters from Ganga canal system were within or at margin in comparison to permissible limit of ISI and WHO for drinking water and therefore, may be suitable for domestic purposes, but it require noticeable consideration due to extreme changes in climate and increase in pollution.

AN APPROACH OF CANONICAL CORRELATION ANALYSIS, RISK ESTIMATE ANALYSIS AND RESPONSE SURFACE METHODOLOGY TOWARDS FACTORS THAT AFFECTING THE EFFICIENCY OF MANAGEMENT OF VESSELS

Previously, there were many maritime casualties has been recorded particularly throughout the time when there were no appropriate regulations or guidelines on safety. Finally, International Safety Management Code (ISM Code) was introduced to enhance the maritime safety of vessels above 500 Gross Register Tonnage (GRT) while the ships below 500 GRT are exempted from this regulation. Thus, vessels below 500 GRT does not have regulations or a system to be referred for a safe navigation and management and increase the risk of exposing to hazards. Consequently, the purpose of this study is to find out the factors contributing towards ineffective management in the absence of proper management system on vessels below 500 GRT. A sample consists of 324 respondents (focused group) from varies field in shipping industry was collected using questionnaire forms as an instrument and analyzed using Canonical Correlation Analysis (CCA), Risk Estimate Analysis (REA) and Response Surface Methodology (RSM). In canonical correlation analysis, the  summary table and correspondence map indicates  that majority of the respondents strongly agreed that external factor is the most associated factor with the efficiency of the management, followed by human error and inefficient management factors in agree category and stability factors were placed under unsure category.

IMPROVED METHOD FOR INOCULATION OF MICROORGANISMS

We studied a new method for inoculation of microorganisms to improve homogenization and their growth on plates. We named the method of Technique of Inoculation in test-Tube (TIT). It showed some advantages when compared to pour plate method such as facility and rapidity of preparation, besides easy homogenization. Using TIT, the growth of the microorganisms was reduced to 14 hours. The method was tested for counting total microorganisms in sugarcane juice using image software.

IMPACTS OF INTEGRATED RICE-PRAWN-FISH CULTURE TECHNOLOGIES ON THE LIVELIHOOD OF RURAL FARMERS

Rice-prawn/fish culture practice has been established in southern parts of Bangladesh since 1990’s, but very new in North-central region. This study was conducted with a view to describe the impacts of rice-prawn-mola-carp polyculture technology on the livelihoods of poor and marginal farmers of Gouripur Upazila in Mymensingh district, based on sustainable livelihoods framework. Freshwater prawn (Macrobrachium rosenbergii) and mola (Amblypharyngodon mola) also called small indigenous fish species (SIS) are important fisheries resources of Bangladesh. These species were introduced in rice-fish culture system of 15 farmers in the study areas. Socio-economic data were collected after completion of the experiment. Almost all the prawn farming households reported that the introduction of rice-prawn/fish culture technology ensured regular supply of SIS and large fish for home consumption, which played an important role in combating protein and micronutrient deficiency for poor, marginal and sub-marginal rural households. Another aspect of rice-prawn/fish culture technology was that it provided rapid return of investment by selling of freshwater prawn/fish and created opportunities for household savings.

ESTIMATION OF CRUDE CAFFEINE IN DIFFERENT TYPES OF TEA

Caffeine  is  a  xanthine  alkaloid  found  in  various  sources  such  as  cocoa  seeds, coffee  beans, tea  leaves, etc. Its content in tea is estimated by methods like spectroscopy, thin layer chromatography, liquid- liquid extraction, etc.  In  this  study, the  content  of  crude  caffeine  was  estimated  using  techniques  like  liquid- liquid  extraction  and  thin  layer  chromatography (TLC). It  is  the  presence  of  caffeine  in  tea  that  keeps  us  alert  and  active  and  enables  us  to  work  efficiently  when  consumed  in  proper  amounts. This  aromatic  compound  on  one  hand  can  help  fight  against  diseases  like  cancer  while  on  the  other  hand  can  harm  ones  health  by  increasing  heart  rate  and  blood  pressure  and  causing  mental  ailments  like  depression  and  anxiety  when  consumed  in  small  amounts.
