Abstract: this research deals with the viability study of using stem cuttings with three different diameters, related to three different positions in the cassava plant (manihot esculenta crantz), and evaluating the effects of such stem cuttings on the emergence, velocity, number and weight of tuberous roots per plant and yield of three cassava cultivars. the field research was conducted in piracicaba, sp, brazil, during two years, from september 23, 1980 to july 23, 1981, and september 1, 1981 to july 20, 1982. the mature and healthy stem cuttings were obtained from 12 month old plants of the mantiqueira, ja?an? and pirassununga cultivars. these cuttings (20 cm long) were divided into three diameter size classes: 2.6 ± .2 cm, 2.0 ± .2 cm and 1.4 ± .2 cm, representing stem cuttings taken from the main stem, the primary and the secondary ramification of the mother plants, respectively. the experimental design was a 3 x 3 factorial in randomized blocks with nine treatments in five blocks. the following conclusions are based on the results obtained: 1. the stem cutting vigor is more significantly shown in the stage of plant emergence. 2. refering to the initial phases of the development, stem cuttings with 2.0 ± .2 cm or 2.6 ± .2 cm of diameters are prefered. 3. a smaller number of tuberous root yield per plant is compensated by a major tuberous root weight. 4. neither stem cutting diameter nor stem cutting position influenced on root production per area. 5. the three cultivars used in the experiment showed a high root yield, and the cultivar mantiqueira was the most productive.

Scientia Agricola , 1998,
Abstract: Realizou-se esta pesquisa com a finalidade de se estudar a viabilidade da utiliza o de manivas com três diferentes diametros relacionados a três diferentes posi es nas plantas de origem, avaliando-se seus efeitos na emergência, desenvolvimento e produ o de três cultivares de mandioca (Manihot esculenta Crantz). A pesquisa no campo foi realizada em dois anos, durante o período compreendido entre 23/09/1980 e 23/07/1981 e entre 01/09/1981 e 20/07/1982, em Piracicaba, SP. Ramas maduras e sadias foram obtidas de plantas com cerca de 12 meses de idade, pertencentes aos cultivares Mantiqueira, Ja an e Pirassununga. Destas ramas, foram preparadas manivas com comprimento de 20 cm e diametros de 2,6 ± 0,2 cm, 2,0 ± 0,2 cm e 1,4 ± 0,2 cm, representando, respectivamente, manivas retiradas das hastes principais, ramifica es primárias e ramifica es secundárias das plantas de origem. O delineamento experimental foi um fatorial 3 x 3 em blocos casualizados com nove tratamentos e cinco repeti es. Foram determinados a velocidade e porcentagem de emergência, número de raízes tuberosas por planta, massa da raiz e o rendimento de raízes. De acordo com os resultados obtidos pode-se concluir: 1) O vigor da muda de mandioca, expresso através dos diversos diametros da maniva, manifesta-se significativamente no estádio de emergência da cultura; 2) Manivas com 2,0 ± 0,2 cm ou 2,6 ± 0,2 cm de diametros, retiradas respectivamente das ramifica es primárias e hastes principais, devem ser preferidas para maior velocidade e porcentagem de emergência; 3) Menor número de raízes tuberosas produzidas por planta é compensado pela maior massa individual da raiz; 4) Para a produ o de raízes por área, é indiferente a utiliza o de manivas com diametro de 2,6 ± 0,2 cm, 2,0 ± 0,2 cm e 1,4 ± 0,2 cm; 5) Os três cultivares utilizados no experimento s o de alto rendimento em raízes, destacando-se o cultivar Mantiqueira.
One year clinical audit of the use of blood and blood components at a tertiary hospital in Nigeria
O.P Arewa
Nigerian Journal of Clinical Practice , 2009,
Abstract: The appropriate use of blood and blood components remains a formidable challenge faced by clinicians particularly in a developing country like Nigeria. The inadequate supply of safe blood implies that measures aimed at ensuring judicious use of the available supply should be continually identified and explored. Aprospective study to evaluate all blood and blood component transfusions over a period of one year from January to December 2004 was done. The appropriateness of the transfusion with respect to the clinical state and the transfusion needs of the recipientwas assessed by aHaematologist. A total of 682 transfusion episodes were reviewed and analyzed. The commonest indication for use blood/blood componentwas severe anaemia in 38% of cases.Twenty nine percent of transfusions formoderate anemia, and 36%of fresh frozen plasma transfusions were found to be unnecessary. Inappropriate transfusion ismostmarked in the setting of platelet transfusionwith81%of platelet transfusion being inappropriate. Enhanced capacity for component preparation, regular auditing of transfusion practices aswell as improved communication between the clinicians and laboratory physicians will lead to more judicious use of blood component therapy. The need for the development of guidelines for blood component use in hospitals in linewith the national blood transfusion policy is highlighted.
Raw Materials Development, Machinery and Manufacturing in Nigeria
O.P. Folorunso
Research Journal of Applied Sciences , 2012,
Abstract: Materials have always been closely associated with human progress. This is because the human species make things like clothing, tools, homes, weapons, vehicles, electronic device, etc and of course, all these products must be made out of the appropriate materials with the required properties in the specified shapes and often with a desired appearance. This study is therefore focusing attention on development, machinery and manufacturing of raw materials to make aforementioned things, this paper also assessed the performance of relevant agencies towards raw materials development and establishing national standard coupled with other activities aimed at reducing the nations over reliance on imported materials. Finally, the study set out primary functions of research centers with sole aim of achieving a development of raw materials to reduce the use of imported materials based on a well articulated material programme on material production and supply.
Bridging the gap between outputs of clinical research and utilisation towards improved healthcare outcome in Nigerian hospitals.
O.P Arewa
Nigerian Journal of Clinical Practice , 2010,
Abstract: Worldwide clinical research efforts do not necessarily translate to improved outcomes in clinical practice. However, with the rising challenge facing clinicians in the midst of an environment of increasing health care choices, rising expectations and limited resources, the awareness of this lag is rising globally and health authorities in collaboration with the clinicians in many countries are taking specific measures to address this issue.While certain contributory factors to this problemcould be universal and possible solutions generalized, some other issues are specific to socio-political and economic circumstances.This article examines two critical issues of attitudinal barriers and institutional defects contributing to this gap in the Nigeria situation and suggests possiblemeasures for improvement. “Much knowledge if out of proportion to the disposition of forces, is invalid, however formally correct it may be” TheodorAdorno (German philosopher&sociologist 1903 -1969). “I am dying with the help of too many physicians”.

Economics of Development , 2011,
Abstract: After having gained independence Ukraine has become an active participant of the global migration process, as well as an important object of the world labor market. Fast increase of volume and intensity of the world labor resources exchange defines the research topicality of the Ukrainians participation in this process, its role and importance.The aim of the article is to analyze the volume dynamics and geographical settlement of the Ukrainian labor migrants on the basis of the official and expert data.The research, devoted to this subject in the Ukrainian scientific literature, was carried out by E. Libanova, O. Malynovska, O. Khomra, I. Prybytkova, O.Pyshchulina and others.The research carried out by the Russian scientists such as I.V. Ivakhniuk, V.O. Iontseva, M.G. Kolosnitsyna, Zh.A. Zayonchkovska, V.I.Prevedentseva, O.V. Tiuriuranova and other is devoted to the international labor migration dynamics problem.On the basis of the carried out analysis we can state the existence of certain transformation concerning dynamics and geographical settlement of the labor migrants in the indicated countries and define the following periods: 1) till the end of the 90-s – migration to Russia, Poland, Chekh Republic; 2) the end of the 90-s – the beginning of the 2000 – partial decrease of migration to Russia andincrease ofmigration to Greece, Italy, Spain, Portugal; 3) decrease of a number of migrants to Portugal and Greece, skyrocketing of the volume of migration to Russia, US, and Great Britain. Nevertheless, this analysis is not complete because it should be added with further empirical estimations concerning qualification, age, and gender of the Ukrainian labor migrants as well as the basic reasons and consequences of labor migration from Ukraine.

The Subaltern and the text: Reading Arunhati Roy’s The Good of Small Things

Journal of Asia Pacific Studies , 2010,
Abstract: More than sixty years have passed since Indian gainedits political autonomy, but the fact remains that women anduntouchables living in Indian society are yet to witnessfreedom in a truer sense. Women, of course, have witnessedsome improvement in their status, and now most of them aregetting education, which was previously declined to them.But their conditions remain problematized as they continueto be at the receiving ends both - in their own houses as wellas outside their domestic spheres. Untouchables, on theother hand, continue to occupy the lower strata in the socialhierarchy. Still, they are considered to be defiled creations ofthis earth having no rights for their (re)formation. PostcolonialIndia has given birth to various political parties buteven they have failed to strengthen the deplorable conditionof untouchables. Ironically, many political parties merely usethem as perfect weapons to secure their personal favoursand as many votes as possible. This increasingly paradoxicalstatus of untouchables – although they are powerless yetthey have an inherent capacity to give power to others – isone of the most contested issues, along with theempowerment of women, which lies central to the field ofpost-colonial studies.
