Today, various methods have been developed to reduce the cost and time needed for the preparation and production of bread. One of these methods is using baking premixes to increase ease and create uniformity for bread quality. This research was carried out with the aim of investigating the possibility of producing baking premixes to improve quality and delay the staling of Baguette and Barbary...
The effects of aeration through lid filters on the hyphal growth of Lentinula edodes (oak mushroom) in sawdust cultivation bags were investigated. The aeration treatment levels were traditional 27 mm hole cotton plugs, cotton balls and combinations of seven hole sizes × two hole positions (up and under) in the lids covering plastic bags containing 1.4 kg sawdust medium at 63% moisture that had ...
BACKGROUND AND AIMS Fabrics used in pollination bags may exclude pollen carried by biotic vectors, but have varying degrees of permeability to wind-borne pollen. The permeability of bags to wind-borne pollen may have important consequences in studies of pollination and reproductive biology. The permeability of four fabrics commonly used in the construction of pollination bags was examined. ME...
COVID-19, caused by SARS-CoV-2, was declared a global pandemic on 11 March 2020 the World Health Organization. The has triggered an unprecedented increase in production, consumption and disposal of multiple types plastic-based personal protective equipment (PPE) as measure to reduce infection. Recent research shows that plastic surfaces can serve fomite for coronavirus transmission it remain st...
Polypropylene and PA66 are widely used in our daily life, but they cannot be welded by laser transmission welding (LTW) because of polar differences and poor compatibility. In this paper, grafting modification technology is used to improve the welding performance between polypropylene and PA66. Firstly, the strong reactive and polar maleic-anhydride (MAH) is grafted to polypropylene and infrare...
Tianjin, China’s fifth largest city, suffers from severe environmental problems due to a high prevalence of plastic bag usage. This problem occurs in China’s other major cities as well. On June 1, 2008, a law requiring large retail stores in China to charge for bags was enacted in an attempt to curtail plastic bag consumption. As a result, many plastic bag manufacturing plants were closed. Howe...
There has been growing interest recently in hybrid installations integrating the offshore wind farm and aquaculture as co-existence while optimizing ocean space use. The marine farms beyond coastal or sheltered areas will require mooring to ensure station-keeping of system during storms. In present work, a sub-surface longline is installed fixed at distance from foundations. designed cultivate ...
Abstract Background and Objective: Given that microbial contamination is the third largest cause of mortality caused blood transfusion, the examination of contamination in platelet concentrates is essential in blood transfusion centers. The purpose of this study was to achieve a rapid test for bacterial contamination of platelets concentration. Material and Methods: This laboratory ...
BACKGROUND Polypropylene mesh used as a mid-urethral sling is associated with severe clinical complications in a significant minority of patients. Current in vitro mechanical testing shows that polypropylene responds inadequately to mechanical distension and is also poor at supporting cell proliferation. AIMS AND OBJECTIVES Our objective therefore is to produce materials with more appropriate...
Vectors and bags are basic collection data structures, which are used frequently in programs and specifications. Reasoning about these data structures is supported by established algorithms for deciding ground satisfiability in the theories of arrays (for vectors) and multisets (for bags), respectively. Yet, these decision procedures are only able to reason about vectors and bags in isolation, ...
