In this system, the effort being made is the integration of waste management, starting from the household as a producer, followed by sorting, then depositing it to BSU and ending with delivery to a temporary warehouse so that the waste is handled properly. This article aims to explore the potentials and problems encountered in the management of a Waste Bank which involves the participation of residents while still paying attention to aspects of economic feasibility. The research was carried out using the analitcal descriptive via interview and analysis of primary data owned by BSU ASRI BMP with due observance of scientific principles and maintaining the independence and interests of the authors. From the results of the research it is known that waste valuation efforts by p...

It has been hypothesized that only chicks from immunologically superior fathers can bear the cost of prenatal exposure to high androgen levels. To test this hypothesis we paired roosters from two selection lines, one up- and one down-selected for natural antibodies, with hens from a control line. We measured yolk testosterone and androstenedione levels, and we injected the treatment group of eggs of each female with testosterone suspended in sesame oil and the control group with sesame oil only. We then measured hatching success, growth, and characterised the humoral and cellular immune responses using three different challenges: a PHA, an LPS, and an SRBC challenge. We found that the hatching success, body mass, initial levels of natural antibodies, and the chicks immunological responses to the three different challenges development were affected neither ...

It covered of the number of incidence and cluster of case in the peak of DHF epidemic in rainy season. The data were collected from November 1st 2005 until February 28th 2006 and November 1st until February 28th 2007. The results show that between two peak season there were 433 cases of DHF in 2005-2006 and 66 case in 2006-2007. Based on the prediction of vector distribution there were six large and four small groups in the year of 2005-2006 compared with one large and one small group in the year of 2006-2007. Most of the vector habitat close related with human settlement and the climate perhaps plays the main role in outbreak of Ae. aegypti population.

Interestingly, the association between thyroid hormones (THs) and life history variation has never been considered, despite a close interaction between THs and these physiological traits. Because of the crucial effects on embryonic development, THs can also induce transgenerational plasticity when transferred to developing offspring, for instance, via egg yolks in birds. In this study, we compiled a unique data set of maternal yolk THs in 34 bird species across 17 families and 6 orders, and tested for associations with various life-history traits. Our phylogenetic mixed models indicated that both concentrations and total amounts of the two most important forms of THs (T3 and T4) were higher in the eggs of migratory species than in those of resident species, and that there ...

Diuretics are compounds that can increase the rate of excretion of urine volume and increase the excretion of mineral salts in the urine. The study was to determine the diuretic effect of salak seed extract on the histopathological structure of the kidney. Salak seed extract was made by maceration method using 70% ethanol and then evaporated. Rats were divided into 4 treatment groups, negative control and 3 treatment groups with the administration of salak seed extract for 7 days orally at a dose of 0.28g/kg body weight, 0.56g/kg body weight and 1.12g/kg body weight. The results showed that the treatment of salak seed extract orally for 7 days could increase urine volume. The treatment of dose 1.12g/kg body weight had highest diuretic effect as indicated by the volume of urine produced 5.00 ml. The treatment salak seed extract had no effect on creatinine and u...
