Extra ZZ bosons and low-energy tests of unification

If there is an extra U(1) gauge symmetry broken at low energies, then it may be possible from the charges of the known quarks and leptons under this U(1) to make inferences about how much gauge unification occurs at high scales and about the unification group. (For instance, there are certain observed properties of an extra $U(1)'$ that would be inconsistent with unification in four dimensions at high scales.) A general analysis is presented. Two criteria used in this analysis are (1) the degree to which the generator of the extra U(1) mixes with hypercharge, and (2) the ratio of the extra U(1) charge of the "10" and the "$\bar{5}$" of quarks and leptons.Comment: 27 pages, LaTex, no figures.

UTILIZING EXPECTED REVENUE IN SELECTING OPTIMAL MARKETING ALTERNATIVES FOR FIXED RESOURCE COW/CALF OPERATORS IN THE TEXAS PANHANDLE

Beef cattle enterprises for the 91% of Texas producers with less than 100 cows represent secondary or supplemental enterprises. In most cases the operator is depending on surplus or discretional labor and the alternate use of the physical resources is limited due to topography or environmental factors. These characteristics transform the decision making process from a variable resource allocation problem to a fixed resource problem. Monthly average prices for 300-900 lb stocker steers, divided into 50 lb intervals, are analyzed for three market locations for the period 1992-1999. Consistent price roll back is observed as the price per cwt decreases as the weight increases. However, as the reduction in price is more than offset by the increase in value due to additional weight, the expected revenue per animal increases as weight increases.Livestock Production/Industries,

Effects of Macronutrients on Seed Quality and Profitability Analysis of Sunflower Production in Northwest Pakistan

Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research Farm of NWFP (North West Frontier Province) Agricultural University Peshawar, Pakistan during summer 2006. The experiment was carried out in a randomized complete block design with split plot arrangements using three replications. Six levels of K (0, 25, 50, 75, 100 and 125 kg ha-1) were kept in main plots while four levels of P (0, 45, 90 and 135 kg ha-1) were kept in sub-plots. Increase in K and P levels enhanced seed oil concentration, on the other hand, increase in P level increased seed protein concentration but increase in K level decreased seed protein concentration. Both oil and protein yields per unit area increased significantly with increase in K and P levels. The increase in oil and protein yields of sunflower was mainly attributed to the improvement in yield components and significant increase in seed yield. The highest net returns of Rs. 25268 (grain yield basis) and Rs. 31274 (oil yield basis) was obtained from those plots that received a combination of 100 kg K + 45 kg P ha-1. Application of 100 kg K ha-1 + 45 kg P ha-1 was therefore, recommended for profitable sunflower production in the agro-climatic conditions in Northwest Pakistan.sunflower, potassium, phosphorus, oil, protein, economic analysis, Northwest Pakistan, Farm Management, International Development, International Relations/Trade, Production Economics, Productivity Analysis,

Eco Green Campus pada Gedung Dekanat Fakultas Peternakan

Fenomena pemanasan global kini menjadi isu populer, yaitu naiknya suhu bumi dikarenakan peningkatan efek rumah kaca. Perjanjian Internasional diadakan agar semua negara dapat berkontribusi mengurangi pemanasan global tersebut. Indonesia sudah berkomitmen dengan menurunkan suhu sebesar 2' C. Universitas Brawijaya, salah satu Universitas di Kota Malang memiliki program Eco Green Campus dengan Fakultas Peternakan sebagai Fakultas yang mempelopori namun dari segi konservasi kawasan. Penelitian mengkaji terkait tingkat ramah lingkungan pada Gedung di Fakultas Peternakan. Gedung Dekanat Fakultas Peternakan atau Gedung V dipilih karena termasuk gedung yang baru dibangun dan berlantai banyak. Metode penelitian yang digunakan yaitu deskriptif yang dilakukan dengan observasi lapangan dan studi literatur dengan metode analisa data yaitu metode deskriptif dengan mendeskripsikan data yang didapat sesuai dengan 6 kriteria Greenship-GBCI yang menjadi acuan. Hasil penelitian menunjukan Gedung objek studi tidak memenuhi predikat mengacu pada predikat minimum GBCI, dan perlu adanya rekomendasi dan evaluasi untuk meningkatkan kualitas bangunan melalui tolak ukur GBCI untuk menunjang Eco green campus

Evaluating Dryland Crop/Livestock System Alternatives for Risk Management under Declining Irrigation in the Texas Panhandle

Production budgets for dryland crop and crop/livestock systems are developed to estimate yields, costs and returns for dryland wheat and sorghum and for alternative dryland crop/livestock systems. A crop simulation model aids yield estimation. The yield and return distributions are used to estimate risk and relative risk for included alternatives.Relative Risk, Ogallala Aquifer, Crop-Livestock Systems, Wheat, Sorghum, Crop Production/Industries, Farm Management, Livestock Production/Industries, Production Economics, Productivity Analysis,

Effect of amino acid composition of cereal-based diets on growth of preschool children

The efficacy of two diets, one based on wheat and the other on rice, on the growth (height) of preschool children has been tested in trials lasting 6 months. Both diets provided 2 g vegetable protein and 100 kcal/kg body wt. The increase in height of the children fed the rice-based diet was 0.67 cm/month and that of the children on the wheat-based diet, 0.43 cm/month. The children maintained positive nitrogen balance on both diets. Amino acid analyses of the cooked foods showed the wheat-based diet to be limiting in lysine, methionine, threonine, and isoleucine and the rice-based diet in methionine. However, the rate of growth of the children fed the rice-based diet suggests that methionine was not a limiting factor; the recommended intake of methionine (FAO/WHO) is likely to be higher than the requirements of preschool children
