生态学报 , 2003,
Abstract: Changnienia amoena is a rare species endemic to China, which belongs to Orchidaceae. In order to understand why this plant has been endangered, we studied the phenology,reproduction and community characteristics of C. amoena populations that occurred in southern part of Shennongjia Mountain range. Thirteen plots were sampled to investigate the community composition. Our results showed that C. amoena generally distributed on shaded slope of 15~45°, with altitudes of 1300~1700m. Its buds emerged to above grou...
Simulating Male Selfish Strategy in Reproduction Dispute  [PDF]
P. M. C de Oliveira,S. Moss de Oliveira
Physics , 2002, DOI: 10.1142/S0129183103004413
Abstract: We introduce into the Penna Model for biological ageing one of the possible male mechanisms used to maximize the ability of their sperm to compete with sperm from other males. Such a selfish mechanism increases the male reproduction success but may decrease the survival probability of the whole female population, depending on how it acts. We also find a dynamic phase transition induced by the existence of an absorbing state where no selfish males survive.
Agroindustrialization as a strategy of social reproduction of the family farm
Pelegrini,Gelson; Gazolla,Marcio;
Estudos Sociedade e Agricultura , 2008,
Abstract: the article discusses the process of agroindustrialization of the family agroindustry production in northern gaucho with focus on medium high uruguay territory in rio grande do sul (rs). the aim is to discuss the so-called family farm in this place from its historical process of emergence and establishment, potentialities and current problems such as legislation, production of raw material, income generation, produced products etc. the study concludes that the family agroindustry constitutes an important strategy of social reproduction and rural development as it is responsible for the settlement of families in the field, the diversification of productive activities in rural properties, families' income generation among other roles.
Growth or Reproduction: Emergence of an Evolutionary Optimal Strategy  [PDF]

Quantitative Biology , 2013, DOI: 10.1088/1742-5468/2013/10/P10020
Abstract: Modern ecology has re-emphasized the need for a quantitative understanding of the original 'survival of the fittest theme' based on analyzis of the intricate trade-offs between competing evolutionary strategies that characterize the evolution of life. This is key to the understanding of species coexistence and ecosystem diversity under the omnipresent constraint of limited resources. In this work we propose an agent based model replicating a community of interacting individuals, e.g. plants in a forest, where all are competing for the same finite amount of resources and each competitor is characterized by a specific growth-reproduction strategy. We show that such an evolution dynamics drives the system towards a stationary state characterized by an emergent optimal strategy, which in turn depends on the amount of available resources the ecosystem can rely on. We find that the share of resources used by individuals is power-law distributed with an exponent directly related to the optimal strategy. The model can be further generalized to devise optimal strategies in social and economical interacting systems dynamics.

Prasad PVS,Padmavathy L,Kumar Prasanna,Rao L
Indian Journal of Dermatology, Venereology and Leprology , 1994,
Abstract: 26 years old male presented with two large plaques of lupus vulgaris and a lesion of tuberculosis verrucosa cutis on the right thigh and foot, respectively. Both the lesions were confirmed by histopathological examinations.
Tuberculosis verrucosa cutis of the scrotum
Verma Kaushal,Singh O
Indian Journal of Dermatology, Venereology and Leprology , 1995,
Abstract: A 13-year-old boy had asymptomatic slowly progressive warty growth on the scrotum for 4 years. Examination revealed a 4 cm x 2 cm keratotic, nontender, indurated plaque on the right side of the scrotum. Histopathological examination of the lesion showed epithelioid cell granuloma with giant cells and lymphocytes in the dermis. Mantoux test was 15 mm x 20 mm. A diagnosis of tuberculosis verrucosa cutis of the scrotum was made. Six months of therapy with INH 150 mg and rifampicin 300 mg daily resulted in complete clearance of the lesion,

Our Dermatology Online , 2012,
Abstract: A 38year old man had asymptomatic slowly progressive warty lesion on extensor surface of left elbow and arm for about 20 years. Examination revealed larger one sized of 16cm×15cm and smaller one about 8cm×5cm. Lesions were Keratotic, verrucous, nontender, cauliflower-like indurated plaque. Mantoux test resulted 20mm×18mm on 48 hours observation. Histopathological examination of the lesion showed epitheloid cell granuloma with giant cells and lymphocytes in the mid dermis. The conclusive diagnosis was tuberculosis verrucosa cutis based on above findings. Six month therapy with INH 300mg plus Rifampicin 600mg supplemented initial 2 months ethambulol 1000mg plus pyrazinamide 1500mg daily resulted complete clearance of the lesions.
