Many sources of raw materials which allegedly can enrich the nutrient content in the organic fertilizer. The weakness of organic fertilizer for this is the low level of nutrients contained in them.This study aims to determine the nutrient content contained in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material.This study aims to determine the nutrient content in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material. The experiment used a completely randomized design with raw materials as treatments, Livestock Waste Rabbit (LTK), Cow Manure (PKS) and Abu Straw Rice (AJP). Such treatment: B1 = LTK; B2 = LTK: PKS = 2: 1; B3 = LTK: AJP = 3: 1; B4 = LTK: PKS: AJP = 6: 2: 1; B5 = LTK: PKS: AJP = 5: 2: 1; B6 = LTK: PKS: AJP = 4: 2: 1; B7 = LTK: PKS: AJP = 3: 2: 1; B8 = LTK: PKS: AJP = 2: 2: 1; B9 = LTK: PKS: AJP = 1: 2: 1. The research concluded (a) Organic fertilizers are made from various materials raw has fulfilled SNI 19-7030-2004 about the specifications of Organic Waste Compost. (B) A combination of organic fertilizer raw materials significantly affect the nutrient content of manure. (C) Organic fertilizers expectations are: (a) Raw materials of animal wastes rabbit (LTK), (b) LTK: PKS: AJP = 6: 2: 1, (c) LTK: PKS: AJP = 2: 2: 1 and (d) LTK: PKS: AJP = 1: 2: 1.

Castings from earthworm (Eisenia fetida) when fed on sheep (SC), cow (CC), or horse (HC) manures were evaluated on growth of Dendranthema `Miramar' cuttings. Castings were produced placing 100 L of manure and 1 kg of earthworms in a 212-L plastic container for each animal manure. Mixtures of peat moss and castings at 0:1, 1:3, 1:1, or 3:1 were evaluated for each animal waste with 100% peat and Sunshine Mix 1 used as the controls. Each media treatment was replicated eight times with each replication consisting of four cuttings per 1-L (15-cm diameter) plastic container. Leachate pH and nutrient content increased as the amount of castings in the media increased. Plant growth index, leaf area, and number of flowers were greatest in media consisting of SC at 1:1 and 3:1 peat:castings. Similar results for growth index and leaf area were obtained with CC at 3:1 and 1:1, respectively. Increasing the amount of castings in the substrate reduced the plant dry weight and increased shrinkage of the media.

Vermicomposting is the scientific method of making compost by using earthworms. It is the cheap and effortless way for producing the organic compost. vermicompost is a backbone for enhancing the organic movement. the research was carried out in the kapilvastu district Nepal under the direction of Dr. Deepak kholiya (A professor of Graphic era hill university).to see the rapid method of vermicomposting and to use animal waste such as cow dung in the effective manner. Eisenia foetida an species of earthworm was used for the conversion of animal waste into the compost. In research we used two methods of vermicomposting i.e.,1. Pit method of size 5*5*3 feet 2. Bed method of size 6*2*2 feet. 200earthworms of same size were introduced in the both methods i.e., body length 3-10 cm body weight 0.4 to0.6 g. The substrate used in vermicomposting is rice straw along with chopped vegetable waste are mixed with the cow dung. Vermicompost sample of both methods are collected. Compost from bed method was collected after 60 days (about 2 months) and pit method was collected after 30-35 days (about 1 month 4 and a half days). both the vermicompost sample were high in nutrient content.

We describe an investigation of the electrical properties of interfacial dislocations in strained layer heterostructures. We have been measuring both the structural and electrical characteristics of strained layer p-n junction diodes simultaneously in a transmission electron microscope, enabling us to correlate changes in the electrical characteristics of a device with the formation of dislocations.The presence of dislocations within an electronic device is known to degrade the device performance. This degradation is of increasing significance in the design and processing of novel strained layer devices which may require layer thicknesses above the critical thickness (hc), where it is energetically favourable for the layers to relax by the formation of misfit dislocations at the strained interfaces. In order to quantify how device performance is affected when relaxation occurs we have therefore been investigating the electrical properties of dislocations at the p-n junction in Si/GeSi diodes.

Semiconductor devices require metal contacts for efficient collection of electrical charge. The physics of these metal/semiconductor contacts assumes perfect, abrupt and continuous interfaces between the layers. However, in practice these layers are neither continuous nor abrupt due to poor nucleation conditions and the formation of interfacial layers. The effects of layer thickness, deposition rate and substrate stoichiometry have been previously reported. In this work we will compare the effects of a single deposition technique and multiple depositions on the morphology of indium layers grown on (100) CdTe substrates. The electrical characteristics and specific resistivities of the indium contacts were measured, and their relationships with indium layer morphologies were established.Semi-insulating (100) CdTe samples were cut from Bridgman grown single crystal ingots. The surface of the as-cut slices were mechanically polished using 5μm, 3μm, 1μm and 0,25μm diamond abrasive respectively. This was followed by two minutes immersion in a 5% bromine-methanol solution.

Food composition data (FCD) comprises the description and identification of foods, as well as their nutrient content, other constituents, and food properties. FCD are required for a range of purposes including food labeling, supporting health claims, nutritional and clinical management, consumer information, and research. There have been differences within and beyond Europe in the way FCD are expressed with respect to food description, definition of nutrients and other food properties, and the methods used to generate data. One of the major goals of the EuroFIR NoE project (2005 - 10) was to provide tools to overcome existing differences among member states and parties with respect to documentation and interchange of FCD. The establishment of the CEN’s (European Committee for Standardisation) TC 387 project committee on Food Composition Data, led by the Swedish Standards Institute, and the preparation of the draft Food Data Standard, has addressed these deficiencies by enabling unambiguous identification and description of FCD and their quality, for dissemination and data interchange. Another major achievement of the EuroFIR NoE project was the development and dissemination of a single, authoritative source of FCD in Europe enabling the interchange and update of data between countries, and also giving access to users of FCD.
