Madan M,Mahesh M.S.,Vijay P. Agrawal,Avinash P. Reddy
Journal of Medical and Allied Sciences , 2012,
Abstract: We present a rare case of idiopathic calcinosis of scrotum. The patient presented with multiple scrotal swellings associated with on and off itching and without any other symptoms for 3 years. These swellings were clinically diagnosed as multiple sebaceous cysts of scrotum. Histopathological examination revealed calcinosis of the scrotum.
Vulnerable Earthworm Species Identified from Nilgiri Biosphere Reserve
Mahesh Mohan,M.S. Shylesh Chandran,E.V. Ramasamy
International Journal of Zoological Research , 2011,
Abstract: Diversity of earthworms at Nilgiri Biosphere Reserve is less known even though it is one among the biodiversity hot spots. Unless an authentic record of available earthworm species is made, the consequences of human alternation or climate change on the earthworm species diversity cannot be assessed. In this regard, the present study is relevant. Earthworms were collected from twenty three sites of NBR. The findings of this study showed that out of the total earthworm species identified from selected areas of NBR, 83.4% are native species and 16.6% are exotic. This indicates the predominance of native species in the study area possibly due to low level of disturbance in the area. Among the species identified from Mukurthi, Priodichaeta pellucida (Bourne) which is listed as vulnerable and has not been encountered since its discovery about 100 years ago.
Influence of SiO2 Fillers on Sliding Wear Resistance and Mechanical Properties of Compression Moulded Glass Epoxy Composites  [PDF]
B. Shivamurthy, ? Siddaramaiah, M.S. Prabhuswamyc
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.87045
Abstract: The E-glass woven fabric-epoxy (LY 556) (GE) composites have been fabricated with varying amounts of silicon oxide (SiO2) particulate filler viz., 3, 6 and 9 wt % by compression molding followed by hot curing. The fabricated composites were characterized by mechanical properties such as tensile behaviour, flexural behaviour and interlaminar shear strength (ILSS). The effect of silica content on the sliding wear properties such as wear loss, specific wear rate and coefficient of friction of GE composites have been investigated at velocity of 5m/s and constant abrading distance of 1200 m with different loads viz., 30N, 60N and 90N by using pin-on-disc machine. Wear out surface of all the composites were studied using scanning electron microscopy (SEM).
A new concept of relatedness and its significance to the theory of social evolution
Drummond, M.S.;
Genetics and Molecular Biology , 2000, DOI: 10.1590/S1415-47572000000100008
Abstract: data on primitively social groups of hymenoptera have been somewhat contradictory with respect to kin recognition, degree of relatedness and social evolution. this study presents a new concept of "relatedness coefficient". called "aggregated relatedness", the hypothesis here introduced proposes that genes shared by any two individuals affect formation of family units to an extent dependent on their frequency and manner of dispersion in neighboring populations.
LETTER TO THE EDITOR: Paediatric and Neonatal Resuscitation
M.S. Kibirige
African Health Sciences , 2001,
Abstract: Resuscitation: Saving lives is the primary responsibility of secondary care services. Many patients arrive in hospitals when they are acutely ill and are hoping for rescue treatment that will save their lives, but also deal with the primary cause of the acute illness. It is therefore important that all staff involved in the care of such patients is adequately trained and proficient in delivering that service. Resuscitation can be defined as the act of reviving. Many of our patients who are acutely ill do require resuscitation, if further treatment is to be effective and successful. Thus, the necessity for resuscitation is not questionable. In Mulago teaching hospital many children are admitted via the acute care unit (assessment unit) and babies in the maternity unit as well as those in special care baby unit do require resuscitation. In this paper I have tried to discuss the various components of resuscitation, provide experience of the training programme, that has recently been performed and the results.

Validity and Reliability Indices of Three-Multiple Choice Tests Using the Confidence Scoring Procedure
M.S. Omirin
The Social Sciences , 2013,
Abstract: The study investigated the validity and reliability indices of three multiple choice tests, using the Confidence Scoring Procedure (CSP). The study also sought to determine whether or not the validity and reliability indices would be improved, if the tests were scored using the confidence scoring method. The population consisted of all SS2 secondary school students in Gbonyin Local Government Area of Ekiti State, Nigeria. The sample consisted 450 SS2 mathematics students, selected by the purposive and proportional sampling techniques. The instrument was a 50-item achievement test in mathematics of three formats each, the instrument was administered on the students as a class test. The three multiple choice tests were mixed and the testees did not know that they were answering different forms of the same tests. The responses were scored using the confidence scoring method. Two null hypothesis were generated and tested at 0.05 level of significance, using Kuder-Richardson`s formula 20, Z-ratio and correlation. The result showed that the contribution of blind guessing to testees was not directly related to the validity of the three multiple choice tests used. The confidence scoring procedure improved the reliability index of multiple choice of the tests used, except the validity of the 3-alternative choice. The result also showed that confidence scoring procedure rewards partial knowledge of testees on multiple choice tests. Based on the findings above, it was recommended that the confidence scoring method should be encouraged, since it improves validity and reliability indices of tests.
Validation Study of the Youth Problems Inventory
M.S. Omirin
Pakistan Journal of Social Sciences , 2012,
Abstract: The purpose of this study was to validate the Youth Problems Inventory (YPI). The sample for the study consisted of 150 students drawn from the part four faculty of Education of the university of Ado-Ekiti and part three students of the college of Education, lkere-Ekiti. The males numbered 85 while the female were 65. ne hundred and twelve were single while thirty eight were married. The ages range from 18 years to 32 years. The research instruments were the Youth Problems Inventory (YPI) and the Student Problem Inventory (SPI). The YPI, constructed by Okon in 1979, is designed for evaluation of students` problems. It was the main instrument. The SPI, constructed by Bakare in 1970, is a checklist meant to evaluate secondary school students` problems. It served as the validating instrument. To assess the reliability of the Youth Problems Inventory (YPI), test-retest reliability method was used with a time interval of two weeks. A reliability coefficient of 0.89 was obtained. Three hypotheses were generated for the study, testing sex, marital status and age groups. The result revealed that there no significant differences in the problems of male and female students, single and married students of different age groups. It was recommended that colleges and universities should try to find out students` problems (using problem inventories) as soon as they are admitted and assist them to get over the problems.
Increasing semiconductor laser-optical fiber coupling efficiency by introducing microlens
M.S. Ozyazici
Optica Applicata , 2004,
Abstract: The efficiency of coupling between semiconductor lasers and single-mode optical fibers can be greatly increased by a microlens of an appropriate focal length being fabricated at the end of the fiber. The reason for this is that the lens can effectively improve the mode matching of the laser and fiber fields. Theoretical work has been carried out to predict this improvement of coupling efficiency as a function of the focal length and spot size associated with the laser and fiber. A simple method was then used to fabricate the microlenses whose focal lengths required a radius of curvature ranging from about 10 mm to 15 mm for maximum coupling. The method comprised in tapering of the fiber to the required radius using a grinder and then with an electric arc and heating the end which next forms into a hemisphere due to surface tension forces. Another way is to dip the tapered end into molten optical glass picking up a droplet of glass.

TISSUE EXPANSION: A NEW MODALITY FOR EYELID RECONSTRUCTIVE SURGERY
M.S. Farahvash
Acta Medica Iranica , 1997,
Abstract: For the first time we have used eyelid skin expansion to facilitate reconstruction of selected patients with shortage of lid skin (e.g. for burn scar and after excision of tumors). This method allows for a controlled increase in skin, need for reconstruction, and offers many advantages over grafted skin transfered from a distance. Color, texture, thinness, delicacy and adnexal structures are aesthetically and functionally better matched. We used expanders in four patients with eyelid skin shortage to prepare suitable flaps for reconstruction successfully.
