Modeling climate variables using time series analysis in arid and semi arid regions
Stochastic models have been proposed as one technique to generate scenarios of future climate change. Temperature and precipitation are among the main indicators in climate study. The goal of this study is the simulation and modeling of monthly precipitation and the mean of monthly temperature using stochastic methods. The 21-year data of precipitation and the mean of monthly temperature at Shiraz Synoptic Station in...

Pre-sowing temperature treatment effect on emergence of Cucumis myriocarpus seedlings
Efficacy of Cucumis myriocarpus fruit crude extracts on suppression of Meloidogyne incognita is well documented in Indigenous Cucumis technologies. Currently, test fruits are collected from the wild, and this unreliable source cannot meet the quantities required for producing a commercial bio-pesticides. Thus, objective of this work was to evaluate effect of temperature-exposure of C. myriocarpus seeds on seedling...

Household dynamics influencing effective eradication of Xanthomonas wilt in smallholder banana systems in Ugunja division - Kenya
Declines in banana (Musa spp.) productivity in western Kenya since 2006 have been exacerbated by Xanthomonas wilt, caused by Xanthomonas campestris pv. musacearum. This study provided insight of household dynamics influencing efforts to eradicate the disease from Ugunja, Lunjre, Sidindi and Sigomere. Surveyed households (N = 120) were purposively selected from villages with and without banana-based farmer field schools...

Recent advances in surgical management of urolithiasis in sheep and goat
The cases of urolithiasis in caprine and sheep presented for treatment for one year to University Teaching Veterinary Clinics were managed surgically. A brief history about the clinical cases, their clinical examination, kidney function tests and ultrasonography was studied. The cases were surgically managed by performing different surgical procedures viz, excision of urethral process, urethrotomy perineal...

Evaluation of chemical composition and nutritive potential of oil palm slurry fermented with cassava peel as feed for livestock
Cassava peels (CaP) and oil palm slurry (OPS) are agro-industrial by-products obtainable throughout the year. Utilization of CaP as feed can be enhanced through fermentation with OPS. The use of CaP fermented with OPS as feed for livestock was therefore investigated with three experiments. The nutrient composition of OPS collected from different locations was determined. Parameters varied significantly with Mamu samples...

A rearing method of the larval parasitoid, Apanteles carpatus (Say) (Hymenoptera: Braconidae) on its new host Monopis crocicapitella (Clemens) (Lepidoptera: Tineidae)
Host suitability of Monopis crocicapitella (Clemens) (Lepidoptera: Tineidae) was tested for a larval parasitoid, Apantales carpatus (Say) (Hymenoptera: Braconidae) under laboratory conditions. Laboratory studies indicated that larvae of M. crocicapitella were successfully parasitized by A. carpatus and fertile offsprings of A. carpatus were produced. Some biological characteristics and a possible rearing method of this...
