Acaricidal Efficacy of Three Organophosphates on Different Stages of Amblyomma variegatum
A.J. Natala,T.R. Ahembe,F.A. Gberindyer,S. Danbirni
International Journal of Animal and Veterinary Advances , 2012,
Abstract: The study was conducted to compare the acaricidal effects of three organophosphorous pesticides, chlorfenvinphos, diazinon and coumaphos as Steladone , Asuntol and Diazintol , respectively. They were evaluated on different stages of Amblyomma variegatum (unfed nymphs, unfed adults and fed adults) using Shaw’s bioassay method. Three concentrations of each acaricides (within the recommendation) were tested on all the ticks’ stages. The highest mortality rate was observed in chlorfenvinphos treatments in all the stages and concentrations tested while diazinon produced the least effect. At the highest concentrations, all the acaricides produced high mortality rates but at the lowest concentration, diazinon was not effective. Generally, the acaricidal effects were concentration-dependent and the least mortality was recorded in the fed adult stage, depicting the possibility of blood and its constituent’s antagonistic interaction with the acaricide. The outcome of this study suggests that chlorfenvinphos and coumaphos could be used interchangeably because of the equivalence in their acaricidal effects. There is also the need for constant screening in order to ascertain Status.
Understanding levels of morbidity and hospitalization in Kerala, India
Dilip,T.R.;
Bulletin of the World Health Organization , 2002, DOI: 10.1590/S0042-96862002000900012
Abstract: the prevalence of ailments and hospitalization in kerala was examined using data from the 52nd national sample survey data on health care in kerala in 1995-6. the survey included 24 401 people from 4928 households. age and seasonality had considerable effects on the morbidity of individuals. the burden of ill health was higher in rural areas than in urban areas. people who were more likely to have a better lifestyle had a higher level of morbidity and hospitalization. regional differences were seen, with levels of morbidity and hospitalization higher in the comparatively developed regions of southern kerala than in northern kerala. factors like physical accessibility of health care services and capacity to seek health care services could create artificial differences in morbidity and hospitalization among different subgroups of the population in kerala.
Caribbean ciguatera: a changing paradigm
Tosteson,T.R;
Revista de Biología Tropical , 2004,
Abstract: analyses of ciguatoxicity in the great barracuda sphyraena barracuda and quantity of toxic benthic dinoflagellates on coastal reefs (correlated with the number of cases of human ciguatera intoxications in puerto rico) were used to construct a model formulated on data obtained during the period of 1985-1988. the validity of the proposed model has been questioned by recent data obtained during the period of 1990-2000. barracuda ciguatoxicity no longer showed a prominent seasonality while the fraction of randomly caught barracuda that were ciguatoxic significantly increased during this period. these two changes, accompanied by the discovery that ciguatoxic fish contained a variety of multiple toxins, appear to be correlated with the steadily increasing periods of elevated sea surface temperatures in this region

Estos hechos fueron utilizados para construir un modelo que fue formulado con la información recopilada durante el período de 1985- 1988. La validez de este modelo propuesto ha sido cuestionada debido a la información recientemente obtenida durante el período 1990-2000. La ciguatoxicidad en la barracuda ya no demostraba una marcada asociación con las temporadas mientras que la cantidad de barracuda ciguatóxica capturada al azar tuvo un aumento significativo durante este período. Estos dos cambios estuvieron acompa ados por el descubrimiento de que peces ciguatóxicos contienen una gran variedad de toxinas que parecen estar relacionadas con los períodos de elevadas temperaturas en la superficie del mar. Estas temperaturas continúan aumentando de manera que a su vez continúan en un aumento estable en esta región
Sistem 3 Strata sebagai Strategi Pemulihan dan Peningkatan Mutu Genetis Kambing dan Domba Indonesia

Media Peternakan , 2005,
Abstract: A modification of conventional production system called “Pyramidal Structure” is presented and termed as a “Sistem 3 Strata”. The system consists of 3 sub systems, they are Breeding, Multiplication, and Commercial. The Pyramidal system had been proven to be very effective in sustaining and improving the genetic potency of layers and broilers (poultry). The system was proposed to be implemented in sustaining and improving the genetic potency of the Indonesian sheep and goats. A simulation was conducted to evaluate the economic feasibility of the system using Garut sheep, based on the assumption of the 15% bank rate, at the capital investment level of Rp 6.400.000.000,00 and the production level of 155 lambs marketed per week. The results indicated that the economic feasibility was reached at the farm capacity of 8.537 su (Sheep Unit). The pay back period was 3,95 years, and the IRR and the NPV (i=20%) at the end of the 6th year were 19,17% and Rp 5.383.297.270,00.

Study of Intermolecular Interactions of Binary Liquid Mixtures by Measuring Intensive Macroscopic Properties at (303.15, 313.15 and 323.15) K and at Ambient Pressure

Modern Applied Science , 2009, DOI: 10.5539/mas.v2n3p16
Abstract: Measurements of thermodynamic and transport properties have been adequately employed in understanding the nature of molecular systems and physico-chemical behavior in liquid mixtures. These properties are important from practical and theoretical point of view to understand liquid theory. In the present study density (?) and viscosity (?), have been measured for a binary liquid mixture of Diacetone alcohol with benzene and chlorobenzene, over the entire composition range at 303.15 K, 313.15 K and 323.15 K and the evaluation of different excess properties. The viscosity values and excess values were fitted to respective models. It was found that in all cases, the data obtained fitted with the values correlated by the corresponding models very well. The molecular interactions existing between the components and comparison of liquid mixtures were also discussed.

R. Baskaran,T.R Kubendran
Modern Applied Science , 2009, DOI: 10.5539/mas.v2n5p91
Abstract: The studies of ultrasonic velocities, refractive indices and surface tension are being increasingly used as tools for investigation of the properties of pure components and the nature of intermolecular interactions between the liquid mixture constituents. Refractive indices (nD), ultrasonic velocities (u) and surface tension (?) have been measured for the binary liquid mixture of Anisaldehyde +benzene over the entire composition range at 323.15 K. This study involves the evaluation of different thermo acoustical parameters along with the excess properties. The Redlich-Kister model was used to correlate the measured properties. It was found that in all cases, the experimental data obtained fitted with the values correlated by the corresponding models very well. The molecular interactions existing between the components were also discussed.
