STUDIES ON CRABS (BRACHYURA): A REVIEW

In this article a number of published papers on crabs both freshwater and marine water crabs are reviewed, we realized that probably there is not a single review paper available on such studies. So we made an effort in order to present a review paper on the crab studies. We observed that different types of works have been done on crabs (both freshwater and marine crabs). The works can be classified into at least four major sets i.e. 1] Anatomy and Body parts, 2] Effect of parameters on Growth [Environmental Factor, Water quality, Pesticides, Chemicals, Metal Salts etc], 3] Compositional and Nutritional Analysis, 4] Applications [Medicinal Applications, Others Applications]

A STUDY TO ASSESS THE EFFECTIVENESS OF A SELF INSTRUCTIONAL MODULE ON THE KNOWLEDGE & PRACTICE REGARDING PROPER BODY MECHANICS AMONG THE CRITICAL CARE NURSES IN SELECTED HOSPITALS OF PUNE

Nursing is known as an occupation with high risk of musculoskeletal injury. Nurses' perceptions about the risk of injury may have a role in preventing such injury.A study to assess the effectiveness of a self instructional module on the knowledge & practice regarding proper body mechanics among the critical care nurses in selected hospitals of Pune.

The study was conducted to assess the knowledge and practice regarding body mechanics among critical care nurses, to evaluate the effectiveness of self instructional module on knowledge and practice regarding body mechanics and to associate the post test findings with the demographic data.

There is remarkable improvement in the knowledge & practice of critical care nurses regarding proper body mechanics after self-instructional module. Corresponding p-value was 0.000 which is small (less than 0.05), the null hypothesis is rejected. Since p-value corresponding to educational qualification is 0.021, which is small (less than 0.05), the null hypothesis is rejected. Since all the p-values are large (greater than 0.05), there is no evidence against null hypothesis. None of the demographic variable was found to have significant association with practices regarding proper body mechanics.

The findings of the study showed that100% nurses experience job related backache. There was a significant association of the educational qualification of the critical care nurses with their knowledge regarding proper body mechanics. The post test score was significantly higher than the pre-test score. Thus the self instructional module was found to be effective.

DEVELOPMENT OF NOVEL MIXED MATRIX MEMBRANES USING 13X ZEOLITE FILLED SA/WPI FOR THE PERVAPORATION DEHYDRATION OF ISOPROPANOL

Novel polymeric membranes were prepared by incorporating different amounts of 13X Zeolite into Sodium alginate/Wheat protein isolate (SA/WPI) blend matrix.  The resulting composite membranes were characterized by Fourier transform infrared spectroscopy and the results were used to analyze the possible chemical reaction between SA/WPI and glutaraldehyde. X-ray diffraction, Scanning electron microscopy, and Differential scanning calorimeter were used to analyze the crystallinity, surface morphology and thermal stability of the membranes, respectively. The membranes were tested for pervaporation studies for water /IPA mixtures at different feed water compositions at 30ºC. The experimental results showed that both flux and selectivity increased with increase in zeolite content. Membrane containing 20 wt% of zeolite shows the highest separation selectivity of 4991 with a substantial flux of 0.120 Kg/m2/h at 30ºC containing 10 wt% of water in the feed, suggesting that the membranes could be used effectively to break the azeotropic point of water-IPA mixture, so as to remove small amount of water from IPA.

PREDICTION OF THE LEVEL OF PSYCHOSOMATIC DISORDERS IN ACCORDANCE TO THE TYPES OF PSYCHOLOGICAL CONFLICT FOR HIGH SCHOOL STUDENTS

The study aimed to know the prediction of the level of disorders in accordance to the types of psychological conflict (sexual, family, social, academic) for high school students based on the gender variables (females & males) and the study specialization variable (Literary & Scientific). The sample of study consisted of 400 male & female students, among them 200 students belong to the Literary scientific branch and other 200 students belong to the Literary and Scientific branch who obtained high marks on Cornel list of Psychosomatic disorders. Two tools were used in the study; the first tool was the Psychological conflict scale (by the researcher), and the second tool was Cornel list for psychosomatic prepared by Keef and others, after ensuring their reliability and validity. The results study showed up the following:

1-The ability of prediction of the level of psychosomatic disorders for all samples of the sexual and academic conflict with hard disorder and light in the domestic conflict.

2-The ability of prediction of the level of psychosomatic disorders for the males sample with scientific and Literary specialization  sample of the sexual and  academic conflict with hard disorder, and light in the domestic conflict.

3-The ability of prediction of the level of psychosomatic disorders for the female sample with scientific and Literary specialization  sample of the sexual and academic conflict with hard disorder, and middle in the social and sexual conflict. The researcher has presented many recommendations.

EVALUATION OF MORPHOLOGICAL AND GEOGRAPHICAL VARIATION IN THE CONTENT OF URSOLIC ACID FROM CARISSA CARANDAS LINN. USING HPTLC

Ursolic acid (UA), a hydroxyl pentacyclic triterpenoic acid found in Carissa carandas Linn., a folk medicine used for the treatment of various diseases and also an important component of plant based medicine. In the present work, a precise, accurate and reproducible densitometric HPTLC method is developed and validated in terms of sensitivity, linearity, recovery, specificity and ruggedness for the estimation of ursolic acid from various samples of Carissa carandas Linn. Chromatographic separation was achieved on silica gel 60 F254 plates with toluene: methanol (8: 1, v/v) as a mobile phase. Detection of ursolic acid was achieved by derivatizing the plate with 10% methanolic sulphuric acid followed by heating at 110°C for 10 min. Camag TLC scanner 4 equipped with winCATS software was used for densitometric scanning at 366 nm. The method was found applicable to evaluate the impact of morphological and geographical variations in the ursolic acid content from Carissa carandas ripe fruits and different morphological parts of Carissa carandas. Ursolic acid content in different morphological parts of Carissa carandas was found in the following order: Fruits > leaves > stems > flowers > seeds. Samples collected from Rajapur showed the maximum content while sample from Lonavla had minimum. The developed method was found useful for quantitation of bioactive marker ursolic acid from different samples of Carissa carandas and can be used as a routine quality control tool for the assessment of botanicals.

EVALUATION OF ROSMARINUS SPECIES EXTRACTED BY DIFFERENT SOLVENTS AGAINST MOSQUITO LARVAE, BIOMOPHALARIA SPECIES AND DIFFERENT PATHOGENIC BACTERIA

The botanical extracts were used as a scours of insecticidal, molluscicidal and antimicrobial agents. Many authors try to improve the potency of these extracts by using different solvents. The pet-ether and ethanolic extracts of Rosmarinus species were tested as insecticidal and molluscicidal agents against Culex pipiens and Biomophalaria alexandrina. The LC50 of pet-ether and ethanolic extracts against mosquitoes were 511.84 & 721.81 ppm respectively. While, LC50 of these extracts against snails were 236.81 & 276.16 ppm respectively. From those results the snails appear more susceptible to both extracts than mosquitoes. Both mosquitoes and snails more susceptible to pet-ether extract than ethanolic extract. petroleum ether and ethanol extracts of  Rosamarinus sp  in different concentrations (5, 10, 15 and 20%) were evaluated for their possible antibacterial activity against six pathogenic bacteria, Staphylococcus aureus and Entrococcus faecalis (gram positive bacteria), Escherichia coli, Proteus sp, Acetobacter sp and Pseudomonas aeruginosa (gram-negative bacteria). The petroleum ether and ethanol extracts of Rosamarinus sp. in different concentrations exhibited antibacterial activity against all tested organisms (except Acetobacter sp was resistant at all concentrations of petroleum ether extract). Findings were compared to those produced by Gentamycin (10 μg) and Tetracyclin (30 μg), reference antibiotic
