This study was conducted to determine the influence of irrigation levels on spring planted sunflower (Helianthus annuus L.) sown with different planting methods. Sunflower was sown either on 60 cm apart single rows on flat seed-bed or on ridges. Three irrigation treatments were I0 (irrigation at early vegetative stage, at bud visible stage, at anthesis and at achene development stage), I1 (irrigation at early vegetative stage, at bud visible stage and at achene development stage) and I2 (irrigation at early vegetative stage, at bud visible stage and at anthesis stage). In I1, irrigation was missing at anthesis and in I2 irrigation was missing at achene development stage. Sunflower yield and yield components showed positive response to ridge sown sunflower with normal four irrigations. Maximum achene yield 3.33 t ha-1 was recorded in ridge sown sunflower with four irrigations. Oil content percentage was highest in case of I0 (42.25%) while the effect of planting methods on oil content was insignificant.

In this paper, rheological characteristics of Metal Injection Moulding (MIM) feedstock using locally binder of palm stearin are presented. The feedstock consisted of 316L-grade stainless steel powder with three different particle sizes and the binders comprise palm stearin and polyethylene. The viscosity of MIM feedstock at different temperatures and shear rates was measured and evaluated. Results showed that, the feedstock containing palm stearin exhibited suitable rheological properties and suitable to produce a homogeneous feedstock that is favorable for injection molding process.

The changes in extreme daily rainfall totals in Punjab Province, Pakistan, during the period (1981- 2014) are examined in this study. The analysis was focused on the extreme annual and monthly rainfall events, by processing the exceeding of the daily rainfall over various thresholds, which are indicators for the incidence of extreme rainfall events. To analyze the changes in extreme rainfall events and trends of the time series of the annual number of extreme rainfall days (%) the thresholds of 30mm and 50mm has been estimated. Evidence from the twelve stations considered shows that there is an increase in annual number of extreme rainfall days (%) in dataset. These changes of heavy and extreme rainfall events pronounce significant environmental consequences which cause considerable impact on society.
