Bioagro , 2003,
Abstract: las distancias de siembra, poblaciones de plantas y genotipos son factores de primordial importancia en las plantas cultivadas ya que determinan la eficiencia de transformar la energía solar en energía química. usualmente, la soya se ha sembrado en hileras separadas a 60-80 cm usando poblaciones entre 300.000 y 400.000 plantas por hectárea, pero la tendencia actual en los principales países productores es acortar las distancias entre hileras y usar poblaciones más altas. el objetivo del presente trabajo fue determinar el efecto de dos distancias entre hileras y tres poblaciones de planta sobre el rendimiento y sus componentes, altura de planta y de carga de dos cultivares de soya [glycine max (l.) merr.] de hábito de crecimiento indeterminado. el estudio fue conducido en el campo experimental del instituto nacional de investigaciones agrícolas (inia) en turén, estado portuguesa, venezuela, durante el ciclo 1997-1998. los factores en estudio fueron distancias entre hileras de 45 y 60 cm, poblaciones de planta a la siembra de 350.000, 450.000 y 550.000 plantas por hectárea, y los cultivares ucla-59s y cristalina. los tratamientos fueron establecidos en parcelas divididas en dise?o de bloques completamente aleatorizados con cuatro repeticiones. el rendimiento de los cultivares en la distancia de 45 cm superó en 25 % al de la distancia de 60 cm. el rendimiento fue mayor a medida que se incrementó la población de plantas. el cultivar ucla-59s produjo un rendimiento mayor al de cristalina en las dos distancias entre hileras y las tres poblaciones de planta.

Abstract: the objective of this research was to evaluate the effect of temperature on the reduction in the soaking period of soybean seeds for the electric conductivity test. seeds were harvested at the r8 stage and 15, 30 and 45 days after r8 and stored in a cold room until physiological quality tests were performed. the electric conductivity test was carried out using the traditional methodology, with four replications of 50 seeds imbibed in water at 25oc for 24 hours, and two other methodologies consisting of 20 replications of 10 seeds imbibed for 10, 30, 60 and 120 minutes at 32oc or 40oc. the results indicated that the increase in the soaking temperature decreases the soaking period to identify soybean seeds with different vigor levels; the electric conductivity test at 32 or 40oc for 10, 30, 60 and 120 minutes is efficient for rapid evaluation of soybean seed quality and the soaking period of 10 minutes at 32 or 40oc already permits classification of seed lots according to theirs vigor level by the electric conductivity test.

Abstract: El polímero poli (VPAVG) pertenece a la familia de materiales bioelásticos derivados de la elastina y ha demostrado poseer cualidades óptimas para la formación de sistemas de cesión controlada, así como una biocompatibilidad aceptable en determinados tejidos. Las formulaciones preparadas a partir del biomaterial deben ser estériles, si se pretende administrar por una vía que implique ruptura de barreras biológicas. Por lo anterior, resulta esencial conocer el comportamiento del polímero y sus formulaciones frente al proceso de esterilización empleado. El objetivo de este trabajo fue, por tanto, evaluar la influencia de la radiación gamma como método de esterilización sobre las ca - racterísticas físicas del poli (VPAVG) y de las partículas for - madas con éste. En cuanto al polímero, no se apreciaron diferencias en su apariencia física antes y después de la esterilización. Sin embargo, las partículas obtenidas a partir del poli (VPAVG) y posteriormente esterilizadas experimentaban cambios en su morfología. En cuanto al tama o de las partículas, se determinó que las obtenidas con polímero esterilizado presentaban cierta tendencia a formar agregados de menor tama o que los encontrados con el polímero sin esterilizar. Se concluyó que el biomaterial ensayado y las formulaciones eran susceptibles a las radiaciones gamma como método de esterilización final, proponiéndose recurrir a otro tratamiento que garantice su esterilidad final. The poli polymer (VPAVG) belongs to the family of bioelastic materials derived from elastin, and it has showed the best qualities for the creation of systems of controlled cession, as well as an acceptable biocompatibility in certain tissues. If any preparation made from this biomaterial has to be administered in any way that implies the rupture of biological barriers, the preparation must be sterile. By this means, it is essential to know the behaviour of this polymer and its formulations, facing the sterilization process being used. The objective of this research was learn the influence of gamma radiation as a sterilization method over the physical characteristics of poli (VPAVG) and the particles formed by it. As the polymer, we did not observe any differences in physical appearance before and after sterilization. Particles formed by the polymer (VPAVG) and sterilized after, experimented changes in their morphology. As the size of the particles, we observed that those obtained with the sterilized polymer showed a tendency to form smaller aggregates than those found with the non-sterilized polymer. We concluded that the essayed

Abstract: the research aimed to evaluate machine traffic effect on soil compaction and the least limiting water range related to soybean cultivar yields, during two years, in a haplustox soil. the six treatments were related to tractor (11 mg weight) passes by the same place: t0, no compaction; and t1*, 1; t1, 1; t2, 2; t4, 4 and t6, 6. in the treatment t1*, the compaction occurred when soil was dried, in 2003/2004, and with a 4 mg tractor in 2004/2005. soybean yield was evaluated in relation to soil compaction during two agricultural years in completely randomized design (compaction levels); however, in the second year, there was a factorial scheme (compaction levels, with and without irrigation), with four replicates represented by 9 m2 plots. in the first year, soybean [glycine max (l.) merr.] cultivar iac foscarim 31 was cultivated without irrigation; and in the second year, iac foscarim 31 and mg/br 46 (conquista) cultivars were cultivated with and without irrigation. machine traffic causes compaction and reduces soybean yield for soil penetration resistance between 1.64 to 2.35 mpa, and bulk density between 1.50 to 1.53 mg m-3. soil bulk density from which soybean cultivar yields decrease is lower than the critical one reached at least limiting water range (llwr =/ 0).

Abstract: proline, glicine betaíne and total soluble protein contents were determined in 12 cuban wheat varieties, of t. aestivum and t. durum species, growing under saline conditions. thus, two experimental variants were conducted based on a concentrated nutrient solution. the first treatment became salty with nacl to an electric conductivity of 8 ds.m-1 and the control treatment without applying nacl. this test was performed under hidropony conditions and treatments were applied from sowing time until 45 days after seed germination, when determinations were recorded. data obtained in the control and stress treatments were compared by t-student test for 5 and 1 % significant levels. as a result, an important increment of proline content was obtained in most varieties, the accumulation in foliage being bigger than in roots. glicine betaíne content was highly significant just in wheat varieties of t. durum species. total soluble protein content showed a rather variable behaviour, even among varieties from the same species; that is why it was not considered an efficient indicator of salinity tolerance. the varieties cuba-c-204, inifat rm-36, inifat rm-37 and inifat rm-26 showed the highest proline accumulation.

Journal of Tuberculosis Research (JTR) , 2014, DOI: 10.4236/jtr.2014.23016
Abstract: Background: The effectiveness of a standard anti-tuberculosis (TB) treatment regimen correlates with in vitro drug susceptibility pattern of the infecting tubercle bacilli. The results of the drug susceptibility tests help select a proper treatment regimen or modify treatment regimen for a better management of patients and surveillance and timely control of the spread of the drug resistant TB in the community. Treatment of drug resistant TB is costly, and the outcomes, including survivorship, can be poor. As the result, the drug susceptibility test has become more important than ever. Objective: To determine the drug-susceptibility pattern of M. tuberculosis and M. bovis isolated from selected sites of Ethiopia. Methods: The conventional indirect Löwenstein-Jensen (L-J) proportion method was used to detect the drug susceptibility pattern of 29 isolates of M. tuberculosis and 21 isolates of M. bovis to four anti-TB drugs (streptomycin, rifampicin, isoniazid and ethambutol). Results: Resistance was observed only in M. tuberculosis isolates while all isolates of M. bovis were fully susceptible to the four drugs. Thus, the overall resistance of M. tubeculosis isolates to any of the four drugs was 51.7%. As such, any type of drug resistance was most frequent to streptomycin (41.3%) followed by isoniazid (20.6%) while it was minimal to rifampicin (6.8%) and ethambutol (3.4%). Multidrug resistant TB (MDR-TB) was not detected in the study. Conclusion: This preliminary study showed high level of resistance in M. tuberculosis isolates warranting appropriate use of anti-TB drugs in those sites from where the isolates were obtained.
相对M-特征标的替换引理
The Replacement Lemma on Relative M-Characters
 [PDF]

郝成功, 靳平
Pure Mathematics (PM) , 2012, DOI: 10.12677/pm.2012.21001
Abstract:
本文主要目的是将M-特征标的替换引理推广到相对M-特征标的情形,证明了如果 均为有限群G的正规子群使得K/L为奇数阶交换群,则G的每个关于L的相对M-特征标也是关于K的相对M-特征标。特别地,如果G为M-群且K为G的一个奇数阶亚交换正规子群,则G也是关于K的相对M-群。
The main goal of the present paper is to generalize the replacement lemma on M-characters to the relative M-characters. It is proved that if are normal subgroups of a finite group G such that K/L is commutative of odd order, then every relative M-character of G with respect to L is also a relative M-character with respect to K. In particular, if G is an M-group with a meta-commutative normal subgroup K of odd order, then G is a relative M-group with respect to K.
