Efeito de diferentes protocolos de superovula??o sobre a concentra??o plasmática de progesterona e de metabólitos lipídicos de vacas Nelore
Ramos, A.F.;Neves, E.F.;Marques, V.S.;Lima, F.P.C.;Drumond, D.L.;Marques Jr, A.P.;
Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2007, DOI: 10.1590/S0102-09352007000200001
Abstract: the purpose of this research was to evaluate the concentration of tryglicerides, cholesterol, aspartate transaminase (ast) and progesterone (p4) in embryo donor nelore cows superovulated with different protocols. twenty four donors were randomly distributed in three groups: group 1 (n=11), donors superovulated with 500ui of fsh and group 2 (n=8) and group 3 (n=5) respectively with 200mg and 180mg of fsh, in decreasing doses, twice a day, during four consecutive days. blood samples were collected before superovulation (a), in the third day of superovulation (b), at the artificial insemination time (c) and at the embryo collection time (d). the concentrations of tryglicerides, aspartate transaminase (ast) and cholesterol were measured by spectrophotometry and progesterone (p4) by radioimmunoassay. there was no alteration (p<0.05) in the concentration of tryglicerides, ast and cholesterol among the samples. there was no effect (p>0.05) of the superovulation protocol on the concentration of tryglicerides, ast and p4 in the samples. in the samples a and b of group 2 the concentration of cholesterol was lower (p<0.05) than in groups 1 and 3, probably due to the instability of the parameter.
Diversidade tipológica do manejo rural feminino no semiárido brasileiro
Vidal,D.L.;
Archivos de Zootecnia , 2011,
Abstract: to better understand the role of women in the agricultural wealth composition, this study aimed to characterize the feminine work diversity in the productive units farming management situated in brazilian semi-arid rural communities. for such, a typology with 75 resident women in six rural communities of the baixo trici district, ceará state, brazil was performed. this typology was based on the feminine work incidence associated or not to another familiar or wage-earning work. seven groups of women had been gotten through the cluster analysis, and they had reflected the feminine farming work diversity in these disfavored rural communities, particularly in the predominant allocation of the women work force for fowl and swine meat and fowl eggs, vegetables gardenorchad and in familiar unit administrative works.
Fator trabalho no manejo rural no semiárido nordestino, Brasil
Vidal,D.L.;
Archivos de Zootecnia , 2011,
Abstract: it is analyzed women micro-economic participation of six different agricultural communities in the city of tauá, inhamuns semiarid microregion, ceará state, brazil (communities of junco, tapera, lustal i, lustal ii, tiassol and queimadas), in relation to the rural tasks management. the family farm production units (fpus) of these rural women represent 75.66% of the participants (n= 103) of the project. the total number of fpus in the 6 communities studied is 305, therefore, the current study encompassed 24.59% of rural women in these communities. the in situ collected data through questionnaires, have been submitted to the frequency, multifactorial and variance statistical analyses. the rural women of these communities are predominantly 45.52 years old with school age children and they do not possess formal education. the partners of women are less interested in interfering in female control of these means of production because they are considered to be of less value in comparison to ro?ado and ruminant management. thus, the women can freely manage these resources for family needs. they appear as main responsible for the fowl, swines and vegetables garden-orchard and are minimaly involved in activities with cultivation and ruminant cattle. from these results the importance of female work is clear for the functioning of the family farm production units in five rural communities (with the exception of tiassol) being studied in the semiarid region in the northeast of brazil.

Contemporary practice...evidence-based and assisted by technology.
D.L. Turpin
Hellenic Orthodontic Review , 2003,
Abstract: AIM: The purpose of this paper is to discuss the incorporation of evidence presented in the orthodontic literature in everyday clinical practice. Issues related to potential implication of irradiation therapy in children with cancer in orthodontic treatment; managing impacted teeth; surgically-assisted palatal expansion; and digital imaging and patient communication, are analyzed.

Managing and coping with names of pleomorphic fungi in a period of transition
D.L. Hawksworth
IMA Fungus , 2012,
Abstract: An explanation is provided of the recent changes in the International Code of Nomenclature for algae, fungi and plants relating to the ending of the separate naming of different states of fungi with a pleomorphic life-cycle. Issues relating to their implementation are discussed, including problems of defining “widely used”, author citations, proofs of holomorphy, typification, the preparation of “Lists of accepted and rejected names” (with a possible timetable), relationship to the existing processes of sanctioning and conservation or rejection, and steps to be considered for the future. This material is presented here to stimulate debate on the actions that should be taken by individuals, and responsible committees, in the current period of transition to a system of fungal nomenclature fit for the 21st century.
A new dawn for the naming of fungi: impacts of decisions made in Melbourne in July 2011 on the future publication and regulation of fungal names
D.L. Hawksworth
IMA Fungus , 2011,
Abstract: A personal synopsis of the decisions made at the Nomenclature Section meeting of the International Botanical Congress in Melbourne in July 2011 is provided, with an emphasis on those which will affect the working practices of, or will otherwise be of interest to, mycologists. The topics covered include the re-naming of the Code, the acceptance of English as an alternative to Latin for validating diagnoses, conditions for permitting electronic publication of names, mandatory deposit of key nomenclatural information in a recognized repository for the valid publication of fungal names, the discontinuance of dual nomenclature for pleomorphic fungi, clarification of the typification of sanctioned names, and acceptability of names originally published under the zoological code. Collectively, these changes are the most fundamental to have been enacted at a single Congress since the 1950s, and herald the dawn of a new era in the practice of fungal nomenclature.
Spatial and Temporal Wave Functions of Photon
D.L. Khokhlov
Applied Physics Research , 2010, DOI: 10.5539/apr.v2n2p49
Abstract: The quantum mechanical model of electromagnetic waves is considered. The photon as a particle moves with the speed of light with respect to the CMB frame. The spatial wave function of the photon is introduced as a wave accompanying the photon, with an infinite speed of spreading throughout the whole space at some moment of time. The temporal wave function of the photon emitted (absorbed) by the electron is defined through the temporal wave function of the electron (virtual photon associated with the electron) at some point of space. The Michelson-Morley experiment is studied with use of both the spatial and temporal wave functions of photon, and the null result being obtained in both the cases.
OPVOEDKUNDIGE TEGNOLOGIE: REKENAARONDERSTEUNDE ONDERRIG IN DIE WEERMAG

Scientia Militaria : South African Journal of Military Studies , 2012, DOI: 10.5787/11-4-684
Abstract: The South African Institute for Educational Research was requested by International Business Machines to conduct an experiment at the Department of Cataloguing and Codification of the South African Defence Force with computer-assisted instruction. Although the experiment did not conform to all scientific standards it did nevertheless show that it is feasible to use computer-assisted instruction.
