The Islamic civilization paid great attention to mechanical engineering during the medieval centuries. The mechanical engineers of the Islamic Empire gave outstanding attention to measurement instrumentation including balances and astrolabes. They used balances to adjust commercial activities in the society and for engineering purposes. They succeeded to use the balance in determining the specific weights of both solids and liquids, examining the purity of precious materials and examining the constituents of alloys. They developed the Greek astrolabe and discovered hundreds of applications required by their daily life. They also devised different type of astrolabes such as the planispheric, quadrant and spherical astrolabes. They wrote 100's of manuscripts explaining the design and use of the astrolabe where some of them still surviving up to now in a large number of libraries and museums around the world. The paper discusses the contribution of Islamic scientists to the development and application of balances and astrolabes.

A total of ten plant samples of Rhus mysorensis (Darsan) from unique locations of Sanganer region of Rajasthan were collected for isolation of fungal endophytes. Of these, maximum frequency of Fusarium species (26.33 %) were recorded which are morphologically similar but ecologically variant. The present paper discusses the diversity of Fusarium species (Fusarium oxysporum & Fusarium roseum) within the Rhus mysorensis plant samples of unique location of sanganer region of rajasthan on the basis of frequency distribution and occurrence.

Butterflies are fascinating creatures of order Lepidoptera have special place in the insect world. The present study was carried out to document the species diversity and abundance from January to December 2011 in the Erode District, using transects counting method. All the butterflies recorded at a distance of 5m from the observer during the counts. Species diversity and abundance is calculated by Shannon –Weiner index. A total of 694 individuals belonging to 23 species of butterflies were recorded during the period and highest numbers of species was recorded from the family Nymphalidae, Papilionidae Pieridae were recorded. Butterflies are sensitive to the changes in the habitat and climate, which influences their distribution and abundance. It is suggest that butterfly species diversity generally increase with increase in vegetation.

Majority of tumours occurring in minor salivary gland are malignant. Pleomorphic adenoma is a benign tumour rare in minor salivary gland of palate. We report a rare case of a minor salivary gland pleomorphic adenoma of the palate in 60 year old female patient who presented with painless slow progressive swelling of palate over the last 7 years. The mass was extending to nasopharynx and oropharynx causing mechanical obstruction of airway and dysphagia. CT scan depicted soft tissue density mass lesion measuring 5 × 4.5cm in the left half of soft palate. Fine needle aspiration cytology was suggestive of pleomorphic adenoma. Complete surgical excision of mass was done. Histopathological examination confirmed diagnosis of pleomorphic adenoma of minor salivary gland. Pleomorphic adenoma must be considered in the differential diagnosis of palatal mass. Timely intervention of pleomorphic adenoma prevents malignant changes.Complete surgical excision is the treatment of choice.Recurrence is rare after complete surgical excision with wide margin. Prognosis is excellent after complete surgical excision.

Library cooperation (LC) stems out of the fact that no library can be self-sufficient in terms of funding and resources available for service delivery. Funding level could affect library collection, staffing, facilities, equipment and even buildings which are all areas where the impact of library cooperation could be visible. The level of resources including funding available to Nigerian universities especially the privately owned makes library cooperation an issue for consideration. Resources to meet vital requirements in some of the institutions are not available and the library is always considered as a minor when allocating resources, this further softens the ground for venturing into Library Cooperation. This paper which studied ten (10) private universities in Southwest Nigeria highlights the areas of Library Cooperation among universities, the process, the progress and the challenges. It concluded that libraries in these institutions are still developing.

This paper presents a method for achieving line loss minimization and voltage regulation in the given power system. In order to achieve these two objectives simultaneously, the Unified Power Flow Controller (UPFC) is used. UPFC can be used for load voltage regulation and total active power loss minimization in electric power systems at the same time. In this paper, the injection model of UPFC (Unified Power Flow Controller) is used to investigate its effects on bus voltages and loss reduction in a power system.

Hyperamylasemia caused by the ectopic production of amylase in multiple myeloma (MM) is rarely described in the literature. It may also correspond to a macroamylase, a complex immunoglobulin amylase. We report the rare case of a patient with MM with Kappa light chains, who developed an accidental discovery hyperamylaseemia without symptoms of pancreatic or salivary disease.We report the rare case of a 61 years old patient, who developed an advanced acute kidney injury, with hypercalcemia, normochromic anemia, associated with diffuse bone pain and accidental discovery of an important hyperamylaseemia without symptoms of pancreatic or salivary disease. Electrophoresis and immunofixation of serum proteins demonstrate a Kappa light chain monoclonal peak. The sternal puncture reveals the presence of dysmorphic plasma cells estimated at 48%. Radiography of the skeleton shows skull geodes at the skull and diffuse demineralization. Abdominal CT does not show signs of pancreatic involvement. The diagnosis is a Kappa light chain MM associated with macroamylase. The patient is treated with the Cyclophosphamide-Dexamethasone-Thalidomide protocol and died of his disease after two months. The interest of this observation is to emphasize this benign biochemical anomaly in order to avoid complementary and / or therapeutic invasive investigations.

Economic globalization has exposed the electric and electronic industrial sector to competition, which is intense and global in character. This situation subsequently influences the capability of firms to plan production based on a new perspective. Affected firms thus implement several strategies to upgrade their competitiveness at the global scale through product upgrading; and this is related to the capacity arising from the producer services sector. Following from the above, this paper aims to examine to what extent industrial upgrading in the manufacturing sector is possible via the integration of the capacity arising from local producer services component, which is in line with the ‘Manufacturing Plus Plus’ strategy of the IMP2. Using research methods such as face-to-face interviews and questionnaire survey and focussing on R&D and IT, this research on the electric and electronic firms in industrial areas in Penang (30 firms) indicates that industrial upgrading efforts in the manufacturing sector could be achieved through the integration of advanced producer services components in the production process. In this respect, this research contributes to current knowledge and understanding (from the perspective of theory and practice) on producer services?manufacturing sector relationship.

The study examined the moderating role of child personality factors in the relation between mothers’ parenting style and child maltreatment in a sample of 330 children aged 7-10 years in Kenya. We found out that mother’s parenting style was a predictor of child maltreatment ?=.25, (p=.01). Mothers who are highly demanding and controlling were more likely to maltreat their children. Extraversion personality factor moderated this relation ?=.29 (p=.04).Thus, children who scored high in extraversion were at a greater risk of child maltreatment by mothers who are highly demanding and controlling. The study highlights the need to train Kenyan parents on positive parenting.

This study considered a method of selecting discrete distributions based on the Katz criterion in fitting an appropriate probability distribution function to available crime data in Nigeria after reasonable transformation. The criterion selected the Negative Binomial distribution for the data under consideration. The adopted distribution provided good fit as evidenced by the Anderson Darling goodness of fit test. This study has therefore applied the Katz criterion to real life data.
