A MICRO-LASER BEAM (1ΜM ) HAS BEEN USED SUCCESSFULLY TO PUNCTURE THE CELL WALL AND CELL MEMBRANE OF EGYPTIAN WHEAT CALLI . USING THE OSMOTIC PRESSURE GRADIENT WE COULD TRANSFER SOME GENES TO THE CELLS THROGH THE INTRODUCED HOLES . WE CONFIRMED THE TRANSFER AND EXPRESSION OF GENES AND ITS STABILITY USING THE ANALYTICAL GENETIC TECHNIQUES AS (PCR) AND (RT-PCR) …

GENERALLY THE THREADED EXTERNAL FIXATOR IS USED FOR FIXATION OF COMPOUND FRACTURES WHICH ARE ACCOMPANIED BY LARGE LACERATED WOUNDS IN NEED FOR DAILY CARE UNTIL COMPLETE HEALING. THE TRADITIONAL EXTERNAL FIXATOR IS COMPOSED OF THREE COMPONENTS, ROD OR LONG TUBE, FIXATION SCREWS AND CLAMP TO HOLD THE SCREW TO THE ROD AND THIS CAUSES SOME DIFFICULTY IN USE ADDED TO …

This invention relates to a method to extract the sugar and produce Ethanol (ethyl alcohol) from the spoiled date. This can be done by adjusting in the used stages in traditional ways, it is the squeezing stage by adding work at high pressure during squeezing and that will increase the amount of sugary liquid, resulting from this stage. By this …

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 …

AIMING TO INCREASE SHIPS SAFETY RATE DURING NAVIGATION IN SHALLOW WATER (CHANNELS & RIVERS, ETC) AND TO REACH NEARLY THE LEVEL OF ZERO ACCIDENTS OR DECREASE GREATLY THE CHANCE OF ACCIDENTS, INNOVATION OF A BRAND NEW METHOD THAT HAS NOT BEEN USED BEFORE IN THE WHOLE WORLD, IT SUPPORTS THE USUAL METHODS USED NOWADAYS. IT IS A NEW PILOT AGE …

DEVICES FOR AUTOMATIC LAUNCHING OF FIRE EXTINGUISHERS BY THREE METHODS, AND TWO THEORIES:A- ELECTRIC MAGNETIC FIELD, (12 VOLTS 1.0 AMPERE) B- HYDRAULIC POWER CONTROL BY USE VOLATILE FLUID, PROVIDED WITH ALARM CIRCUIT(MINIMUM 1.5 VOLT) THE FIRST THEORY: THIS DEVICE MAKES THE FIRE EXTINGUISHER STORAGE PRESSURE (DRY POWDER, FOAM-GENERATION&CO2) WORK AUTOMATICALLY BY AN ELECTRICAL SIGNAL FROM A CONTROL PANEL THROUGH A …

PLANT AND ANIMAL TISSUES ARE SIMILAR. TWO ANIMAL HORRMONES (ETHINYL ESTRADIOL AND LYNESTRENOL) WERE ADDED AT DIFFERENT CONCENTRATIONS TO THE DRENCHING SOLUTION WITH THE FERTILIZING MIXTURE 23:20:20:2 , TO EXAMINE THEIR EFFECTS ON GROWTH AND DEVELOPMENT OF POTHOS PLANT. STATISTICAL ANALYSIS OF THE RESULTS REVEALED A CLEAR RESPONSE IN THE FORM OF CONSIDERABLE ENHANCEMENT OF PLANT HEIGHT, AS WELL AS …
