Walnut (Juglans regia L.) is the oldest fruit grown in world and grows spontaneously almost throughout Romania. In this study, physical properties chemical composition of twenty types walnuts from three different locations Romania were studied. The analyzes that performed were: walnut dimensions shape (nut diameter, nut length, size), (walnut weight, kernel weight percentage kernel) external ex...

Abstract Transportation of heavy crude oil through pipelines poses a great challenge in and gas industry. Crude chokes the when temperature drops below pour-point temperature. In present study, bio-based additive, i.e., Cashew Nut Shell Liquid (CNSL) has been tested as flow improver for crude. CNSL was obtained from waste cashew nut shell by means mechanical extraction, it completely characteri...

Many studies are performed by researchers about Shell and Tube Heat Exchanger but the Multi-Objective Big Bang-Big Crunch algorithm (MOBBA) technique has never been used in such studies. This paper presents application of Thermal-Economic Multi-Objective Optimization of Shell and Tube Heat Exchanger Using MOBBA. For optimal design of a shell and tube heat exchanger, it was first thermally model...

Wood ash has been widely used as an additive for excreta from dry compost toilets to sanitize it for reuse. However, there is dearth of quantitative information about its efficiency in sanitizing partially digested sludge from wet onsite sanitation systems. This paper presents findings of a series of two experimental studies to assess optimum wood ash dosages required to raise the pH of partial...

Walnut is a medicinal plant that its different parts such as leaf, seed, root and green husk was shown to reduce blood glucose. In Iranian traditional medicine, septum of walnut shell (SWS) was recommended to reduce blood glucose. But this effect should be determined with scientific researches. Therefore, the aim of this study is to evaluate the effect of the aqueous extract of SWS on blood glu...

Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam activation of the biochar using the conventional heating to produce activated carbon. Addition...

This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...
