Vermiculite, pine shavings and unbleached eucalyptus pulp contact-bedding were compared using the number of litters and individuals born and weaned, mortality rates at different stages of the lactation period, and the weight increase of pups as evaluation indices for bedding quality. These bedding materials exerted different effects on the reproductive performance of the same mouse strain. The ...

Banana is one of the most important fruits over the world. The chemical composition is critical for the organoleptic properties and health benefits. As one of the leading bioactive components in banana pulp, the polysaccharides may contribute to the beneficial health effects. However, their precise structure information remains unknown. A leading acidic polysaccharide (ABPP) of banana pulp was ...

Vitality of dental pulp is essential for long-term tooth survival. The aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. There are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. Pulp capping or pulpotomy procedures rely upon an accurate assessment of the pulp status, and car...

The cleavage of lignin bonds in a wood matrix is an important step in the processes employed in both the biorefinery and pulp and paper industries. β-O-4 ether linkages are susceptible to both acidic and alkaline hydrolysis. The cleavage of α-ether linkages rapidly occurs under mildly acidic reaction conditions, resulting in lower molecular weight lignin fragments. Acidic reactions are typicall...

This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry. The aim is to review the versatile pollutants and the analysis methods for their determination. Among other pollutants, biocides, extractives, and lignin-derived compounds are major contributors to harmful effects, such as toxicity, of industrial wastewaters. Toxicity of wa...

The present research was accomplished on Phoenix dactylifera L. cv. Shahany to investigate the effect of macro and micronutrients on fruit quality and quantity. Treatments were urea (0.5, 1%), boric acid (1500, 2500 ppm), potassium sulfate (1, 2%) and zinc sulfate (300, 600 ppm). Higher and lower yield were obtained from H BO (1500 ppm) and control, respectively. The greater part of pulp weight...

Osman Chemical Engineering and Pilot Plant Department, National Research Centre, Cairo, Egypt Email: [email protected] Abstract: The waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is condu...

Tomato is a versatile vegetable that is consumed fresh as well as in the form of processed products. More recently, there has been renewed attention given to the antioxidant content of tomatoes because many epidemiological studies suggested that regular consumption of fruits and vegetables, including tomatoes, can play an important role in preventing cancer and cardiovascular problems. Approxim...

Waste from pulp and paper mills consist of sugar-rich fractions comprising hemicellulose derivatives and cellulose by-products. A complete characterisation of the waste streams is necessary to study the possibilities of an existing mill. In this work, four chromatographic methods have been developed to obtain the most suitable chromatographic method conditions for measuring woody feedstocks, li...

this study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (psp) on performance and blood parameters in laying hens. a total of 96 layers hens (hy-line w-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of psp, with 4 replicates containing 6 layers in each. results showed no significant effec...
