IMPROVING THE EFFICIENCY OF BIOFERTILED ROCK PHOSPHATE AS A SOURCE OF NATURAL PHOSPHATE FERTILIZER) BY USING SOME NATURAL AND ORGANIC ADDITIVES

FIRST WE USE A MIXTURE FROM NATURALLY BLENDED PHOSPHATES (AS A PHOSPHATE FERTILIZER) AND PHOSPHATE SOLUBILIZING BACTERIA (BACILLUS SPP.) AS A PHOSPHATE DISSOLVING ORGANISM WHICH PROCESSES THE ABILITY TO TRANSFORM INSOLUBLE PHOSPHATES IN THE ROCK PHOSPHATE INTO SOLUBLE FORMS THIS IS ACLIVED BY SECRETING OF ORGANIC ACIDS (SUCH AS ACETIC AND LACTIC ACID) USING NATURAL OR FERTILIZER, WHICH WILL BE …

A novel approach for the control of the red palm weevil Rhynchophorus ferrugineus (F) using Microsporidia

THE MICROSPORIDIAN VAIRIMORPHA (NOSEMA) EPHESTIAE (MATTES) – (PROTOZOA, MICROSPORIDIA) WAS TESTED AGAINST THE RED PALM WEEVIL (RPW),RHYNCHOPHORUS FERRUGINEUS (F). THE PATHOGEN WAS ISOLATED FROM THE MEDITERRANEAN FLOUR MOTH LARVAE, EPHESTIA KUEHNIELLA ZELL , AND PROPAGATED SUCCESSFULLY ON THE SAME HOST OR ON THE EGYPTIAN COTTON LEAFWORM. THE PATHOGEN CAUSED LETHAL EFFECT TO RPW LARVAE ADULTS WHEN APPLIED AT 25 -100?106 …

UPGRADING THE UTILLIZATION OF AGRICULTURAL AND SYNTHETIC POLYMER WASTES IN PREPARATION OF RO-MEMBRANES FOR DESALINATION OF BRACKISH WATER

THIS INVENTION FOCUSED ON PREPARATION OF ECONOMIC AND HIGH PERFORMANCE REVERSE OSMOSIS MEMBRANES, CHARACTERIZED BY HIGH TRANSPORT PROPERTIES (SALT REJECTION AND FLUX) TOWARDS DESALINATION OF BRACKISH WATER. IN THIS RESPECTCELLULOSE ACETATE FROM SUGAR-CANE BAGASSE (BCA) AND POLYMETHYL METHACRYLATE (PMMA) WASTES WERE USED AS THE SUBSTRATES OF MEMBRANE. THE FUNCTION OF PMMA FOR ENHANCING THE PERFORMANCE OF BAGASSE-BASED CELLULOSE ACETATE RO-MEMBRANES …
