Opis:
Soil fertility evaluation has been considered as a most effective tool for sustainable planning of a particular region. This study was conducted to determine the soil fertility status of the Agricultural Research Station, Pakhribas, Dhankuta, Nepal. The total 60 soil samples were collected randomly at a depth of 0-20 cm by using the soil sampling auger. For identification of soil sampling points A GPS device was used. The collected samples were analyzed for their texture, pH, OM, N, P₂O₅, K₂O, Ca, Mg, S, B, Fe, Zn, Cu and Mn status following standard methods in the laboratory of Soil Science Division, Khumaltar. The Arc-GIS 10.1 software was used for soil fertility maps preparation. The observed data revealed that soil was dark yellowish brown (10YR 4/4) and yellowish brown (10YR 5/6) in colour, and single grained, granular and sub-angular blocky in structure. The sand, silt and clay content were 56.61±0.97%, 27.62±0.56% and 15.77±0.58%, respectively and categorized as loam, sandy loam and sandy clay loam in texture. The soil was very acidic in pH (4.66±0.07) and very low in available sulphur (0.53±0.11mg/kg), available boron (0.24±0.07mg/kg). The organic matter (1.34±0.07%), total nitrogen (0.09±0.003mg/kg), available calcium (605.70±31.40mg/kg), available magnesium (55.96±4.67mg/kg) and available zinc (0.54±0.22mg/kg) were low in status. Similarly, available potassium (115.98±9.19 mg/kg) and available copper (1.13±0.09 mg/kg) were medium in status. Furthermore, available manganese (36.31±2.82mg/kg) was high, whereas available phosphorus (105.07±9.89 mg/kg) and available iron (55.80±8.89 mg/kg) were very high in status. The soil fertility management practice should be adopted based on the determined status in the field for the sustainable production of crops. The future research strategy should be built based on the soil fertility status of the research farm.

Opis:
In the present paper, we have derived an expression for change in entropy of non-spinning black holes on the basis of formula (EBH = KBHRS) as proposed by Kanak Kumari et al. (2010) and the formula δSbh= 2π/(k.c^2 ) δE (Mahto et al., 2011) and calculated their values for different test non-spinning black holes.

Opis:
Toxoplasmosis is a cosmopolitan parasitic zoonosis, infecting human and other warm blooded animals worldwide. This disease has economic importance in regard to animal reproduction, and it leads to abortions and neonatal complications in humans. This study was carried out to determine the seroprevalence of Toxoplasma gondii in sheep, cattle, cats and human in Inaruwa and surrounding areas of Sunsari district, Nepal. Altogether 336 blood samples, of which 50 from sheep, 92 from cattle, 44 from cats and 150 from human were collected and tested immediately using lateral flow chromatographic immunoassay (Toxo IgG/IgM Combo Rapid test®). Associated biometric information such as age, sex, pregnancy status, occupation, association with cat was recorded and analyzed to determine the association of risk factors with the disease. Data were analyzed using R 3.2.2 (The R foundation for Statistical Computing, 2015). Seroprevalence of toxoplasmosis was detected 12.00% (95% CI: 4.53- 24.31%) in sheep, 8.70% (95% CI: 3.83- 16.42%) in cattle, 36.36% (95%CI: 22.41- 52.23%) in cats and 12.67% (95% CI: 7.80- 19.07%) in human. In case of human, 31 to 45 years age group were found more susceptible to toxoplasmosis (21.74%, OR: 6.4) in comparison to 21 to 30 years (10.0%) and up to 20 years (4.17%) age groups. Toxoplasmosis was found highly significantly associated with abortion (58.33%, OR= 15.4, P=0.0001) in human in the tested individuals. Regarding occupation, 20.83% butchers were seropositive followed by farmers (15.52%), housewives (10.0%) and diagnostic lab technicians (8.0%). Female and higher age group showed high prevalence of toxoplasmosis in all studied species. Therefore, this assay is a useful method for the serological screening of toxoplasmosis in different animals and humans.
