Abstract: biomaterials of bovine origin in regenerating segmental bone defects were evaluated. twelve six-month old norfolk rabbits, weighting 3 to 4.5kg were used. a 1cm long segmental defect was created in the radial diaphysis, including the periosteum, of both forelimbs. in the right forelimb, the defect was filled using a mixture of bone morphogenic proteins adsorbed to hydroxyapatite, agglutinant of lyophilized collagen in granules and anorganic cortical bone in granules delimited by a pericardial membrane. in the left forelimb, the defect did not receive treatment and served as a control. radiographies were taken immediately after surgery and at seven, 30, 60, 90, 120 and 150 days post-operatively. six rabbits were euthanized at 60 days and the other six at 150 days post-surgery for histological evaluation. radiographic and histological results revealed that bone regeneration was inhibited in the segmental defects receiving biomaterials.
Graphical exploration of two-dimensional functions an aid to mastering fundamental calculus concepts
T.M. Steyn
South African Journal of Education , 2002,
Abstract: Technology has become an integral part of all educational activities and can be viewed as a powerful lever to promote the understanding of fundamental mathematical concepts that underpin the study of calculus. This article reports on action research activities during 1993-1998 at the University of Pretoria, which focused on aspects that constitute the coherence between teaching, learning, mathematical conceptualisation and the use of computer graphing technology. Results identify some features of graphing utilities that are necessary to enhance fundamental concepts. The principle findings are that the meaningful combination of graphical exploration and graphical analysis according to a well thought-out didactical approach is necessary in order to incorporate technology successfully into mathematics instruction.

International Business Management , 2012, DOI: 10.3923/ibm.2012.68.74
Abstract: This study examines the human resources challenges of the post consolidation mergers and acquisition in Nigeria s banking industry. The industry went through structural changes which has posed great human resources management challenges. The study adopted the survey research design. A sample of 115 respondents was selected from six of the banks that merged to become two. The simple random sampling technique was used in the selection of sample elements. The instrument for data collection was the questionnaire. Four hypotheses were tested. The hypotheses tested indicated a relationship between the mergers and acquisitions and productivity, job security, labour turnover and level of level of technological innovations. The implementation of the consolidation policy induced a shake-off in the industry which infused a new set of human resource challenges in the sector; some of which include those of job-cutting, outsourcing, downsizing, rightsizing, incompatibility in technologies, equipment or corporate culture. The study posits that human resource is an essential part of mergers and acquisitions and should be given adequate emphasis throughout the processes of mergers and acquisitions. Intended objectives may not be achieved when human resources factors are overlooked. For successful integrations, it is imperative that merger talks and negotiation should go beyond the balance sheet figure to an in-depth understanding and evaluation of cultural compatibility that will promote the realization of the objectives. With the emergence of mega-banks employees must be given necessary training and skill development for the current level of activities in today s banks.

Spectro-Structural Characterization of Chalcogenide Films Containing Cd, Te and Se  [PDF]
T.M. Rajakumar, C. Sanjeeviraja, R. Chandramani
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.1011080
Abstract: Chalcogenide films find many applications in electronics as memory device, laser writer & xerography. To tailor the property to the requirement, various compositions of Cd, Te and Se have been deposited and characterized optically. Films have been deposited by thermal evaporation as well as by electron beam evaporation. Thermal analysis such as TGA, DTA and DSC has been carried out before deposition to ensure the composition. Dependence of Eg on the composition has been justified from (T% data) Transmittance measurements. Drastic changes in optical property due to annealing in the range 200°C to 400°C have been investigated.

Abstract: The purpose of this study is to examine the changes exhibited due to implementation of watershed development programme in the study area (Mandhwan Village, Dist. Ahmednagar) in terms of change in landuse, cropping pattern, soil and water conservation, socio-economic development and status of women employment. The study was based on beneficiaries' household survey. It involved acquisition of data through questionnaire survey from a sample of 25% household using systematic random sampling procedure. Data was collected both for pre and after the implementation of watershed development programme. (1990-91 to 2000-01). Besides, intensive field observation was conducted for collecting relevant data. The study revealed that due to implementation of watershed development programme there is increase in net shown area, gross cropped area, area under irrigation, change in cropping pattern, yield per hector, ground water level, and status of women employment in the village. This transformation shows the significance of implementation of such programmes at village level for the upliftment of rural life.
Development of strut and tie models for simply supported deep beams using topology optimization
Praveen Nagarajan,T.M. Madhavan Pillai
Songklanakarin Journal of Science and Technology , 2008,
Abstract: Generally, structural members can be broadly divided into two regions, namely B, or Bernoulli regions, where the strain distributions are linear and D, or Disturbed regions, where the strain distributions are nonlinear While well defined theories are available for designing B regions, rules-of-thumb or empirical equations are still being used to design D regions although B and D regions are equally important. It has been recently understood that the strut and tie model is an effective tool for the design of both B and D regions. Since this method is a realistic approach, this has found place in many codes like Euro code, American code, Canadian code, Australian code, New Zealand code etc. In a deep beam, the distribution of strain across depth of the cross section will be nonlinear and hence these structural elements belong to D regions. The existing code provisions for the design of simply supported deep beams are inadequate and are empirical in nature. In this paper,the development of strut and tie models for simply supported deep beams using topology optimization is discussed. The design of deep beams using topology optimization is illustrated using an example and is compared with available code recommendations.

Abstract: Las imágenes en medicina nuclear y radiología son complementarias y su fusión permite una comprensión integrada, respondiendo a la necesidad de entregar al clínico un formato amigable y confiable de la información.Para SPECT (tomografía por emisión de fotón único) o PET (tomografía por emisión de positrones), distintos radiotrazadores (RT) administrados al paciente revelan el estado funcional de órganos y tumores. Por la relativa carencia de referentes anatómicos, SPECT y PET pueden requerir correlación morfológica dirigida. Su fusión con una tomografía computarizada (CT) o resonancia magnética (RM), constituye una pareja de imágenes de distinta modalidad; SPECT/CT, SPECT/RM, PET/ CT o PET/RM, capaz de localizar focos isotópicos en su estructura correspondiente, que puede o no estar alterada.Con el objetivo de evaluar el valor diagnostico de la Fusión de Imágenes en el Procesador de Imágenes IM512P propuesta por el autor como Protocolo a usarse en los servicios de Medicina Nuclear; se dise o un estudio Observacional, Transversal, Comparativo, Retrospectivo; en el Hospital de Policía Luis N Sáenz, durante los meses de enero a julio del 2007. Se realizo la recolección de imágenes e informes médicos, en las técnicas de Spect y Resonancia Magnética, de 38 pacientes para luego en la estación de trabajo del procesador de imágenes realizar la Fusión de las mismas, y así obtener resultados, y comparar con los valores ya establecidos de sensibilidad y especificidad. Los resultados mostraron valores de Sensibilidad de 96,55% con un índice de confiabilidad de 95% entre 88,19% y 100%, Especificidad de 77,78% con un índice de confiabilidad de 95% entre 45,06% y 100%, Valor Predictivo Positivo de 93,33% Valor Predictivo Negativo de 87,50%, para la Fusión de Imágenes en comparación con el Spect Cerebral.Valores de Sensibilidad de 93,55% con un índice de confiabilidad de 95% entre 83,29 Y 100,0%, Especificidad de 85,71% con un índice de confiabilidad de 95% entre 52,65 y 100%, Valor Predictivo Positivo de 96,67% Valor Predictivo Negativo de 75,00%, para la Fusión de Imágenes en comparación con la Resonancia Magnética.
Chemotherapy induced nausea AND vomiting (CINV)

Abstract: Chemotherapy is the first line treatment in management of many cancers, both for cure and palliation; hence it s crucial to minimize the unpleasant side effects of chemotherapy to increase tolerability to chemotherapy. Most of the conventional anti cancer drugs are emetogenic. Patients receiving chemotherapy experience different degrees of nausea and vomiting depending on the emetogenic potential of the anti cancer drugs given and the patient characteristics. With a better understanding of the pathophysiology, distinct phases of chemotherapy-induced nausea and vomiting (CINV) i.e., acute emesis, delayed emesis and anticipatory emesis have been identified. Identification of various mediators has led to the development of different drugs acting through different mechanisms which are useful in the prevention and treatment of CINV. Serotonin receptor three (5-HT3) antagonists, corticosteroids and neurokinin type one receptor (NK-1) antagonists are of proven usefulness and have wide therapeutic indexes in the prevention of CINV. Other drugs like dopamine receptor antagonists & benzodiazepines are not routinely used because of their narrow therapeutic index. Practice guidelines for prevention of CINV will not only improve patient s tolerability to chemotherapy & wellbeing, but also decrease hospital stay and overall cost of treatment of the patient.
