Konsentrasi Asam Lemak Tidak Teresterifikasi (Nonesterified Fatty Acid, NEFA), Albumin, Kalsium Dan Fosfor Dalam Plasma Sebagai Indikator Status Nutrisi Sapi Perah Laktasi

Tujuan penelitian ini adalah untuk mengetahui status gizi sapi perah laktasi didasarkan pada konsentrasi NEFA (nonesterified Asam Lemak), albumin, kalsium, dan fosfor dalam plasma. Tiga puluh dua sapi perah kepala di periode menyusui kedua digunakan untuk up mengambil plasma darah. Uji t dan regresi sama digunakan untuk berbagai penentu dari konsentrasi. Hasil pengamatan yang berarti dan berbagai konsentrasi NEFA 0.17 mEq.L-1 dan 0,11-0,22 mEq.L-1, albumin 2.69 g% dan 2,51-2,87 g%. Kemudian, mean dan berbagai konsentrasi kalsium plasma 9.39 mg% dan 8,90-9,88 mg%, 8.60 dan 8,10-9,10 mg% dari konsentrasi fosfor plasma. Regresi sama berat plasma NEFA (Y) tubuh (X1), produksi susu (X2) adalah Y = 0,163 X1 + 0,215 X2 (R2 = 11,2%, P> 0,05). Regresi sama plasma albumin (Y), berat badan (X1), produksi susu (X2) adalah Y = 0,197 X1 + 0,006 X2 (R2 = 12,3%, P> 0,05). Regresi sama plasma kalsium (Y), berat badan (X1), produksi susu (X2) adalah Y = -0,099 X1 + 0,389 X2 (R2 = 11,9%, P> 0,05), plasma fosfor (Y), berat badan (X1 ), produksi susu (X2) adalah Y = 0.72 X1 + 0,394 X2 (R2 = 19,2%, P> 0,05). Oleh karena itu, cadangan energi (konsentrasi NEFA), kalsium dan fosfor dalam plasma yang paling persyaratan untuk peningkatan produksi susu

Perturbative Computation of Glueball Superpotentials for SO(N) and USp(N)

We use the superspace method of hep-th/0211017 to prove the matrix model conjecture for N=1 USp(N) and SO(N) gauge theories in four dimensions. We derive the prescription to relate the matrix model to the field theory computations. We perform an explicit calculation of glueball superpotentials. The result is consistent with field theory expectations.Comment: 24 pages, 10 figure

Efisiensi Teknis USAha Tani Padi Petani Peserta dan Petani Nonpeserta Program Sl-ptt di Kabupaten Sukabumi

The objectives of this study were to analyze the influence of farmers\u27 participation in SL-PTT rice program on the technical efficiency of farm businesses run by the farmers. The measurement of technical efficiency was conducted by using Data Envelopment Analysis (DEA) oriented toward the inputs of 35 SL-PTT rice program participants and 35 non-participant farmers of SL-PTT rice program in Cisaat District of Sukabumi Regency, particularly during the harvest season III in 2014. The significant difference of the mean value of technical efficiency between the participant farmers and non-participant farmers of SL-PTT rice program was examined by using t-test (different test). The results show that the average value of technical efficiency for all respondents is 0,83. The average value of the technical efficiency of the participant farmers in SL-PTT rice program (0,84) is higher than that of the non-participant farmers in SL-PTT rice program (0,82). The t-test results also show that the values of technical efficiency between both types of farmers are not significantly different. The development of SL-PTT program can be achieved by improving the delivery methods on the PTT technological information to the participant farmers i.e. by involving farmers who hold a role as progressive farmers to convey information and advice to other farmers

Open String Amplitudes in Various Gauges

Recently, Schnabl constructed the analytic solution of the open string tachyon. Subsequently, the absence of the physical states at the vacuum was proved. The development relies heavily on the use of the gauge condition different from the ordinary one. It was shown that the choice of gauge simplifies the analysis drastically. When we perform the calculation of the amplitudes in Schnabl gauge, we find that the off-shell amplitudes of the Schnabl gauge is still very complicated. In this paper, we propose the use of the propagator in the modified Schnabl gauge and show that this modified use of the Schnabl gauge simplifies the computation of the off-shell amplitudes drastically. We also compute the amplitudes of open superstring in this gauge.Comment: 23 pages, minor correction

Physical mechanisms generating spontaneous symmetry breaking and a hierarchy of scales

We discuss the phase transition in 3+1 dimensional lambda Phi^4 theory from a very physical perspective. The particles of the symmetric phase (`phions') interact via a hard-core repulsion and an induced, long-range -1/r^3 attraction. If the phion mass is sufficiently small, the lowest-energy state is not the `empty' state with no phions, but is a state with a non-zero density of phions Bose-Einstein condensed in the zero-momentum mode. The condensate corresponds to the spontaneous-symmetry-breaking vacuum with neq 0 and its excitations ("phonons" in atomic-physics language) correspond to Higgs particles. The phase transition happens when the phion's physical mass m is still positive; it does not wait until m^2 passes through zero and becomes negative. However, at and near the phase transition, m is much, much less than the Higgs mass M_h. This interesting physics coexists with `triviality;' all scattering amplitudes vanish in the continuum limit, but the vacuum condensate becomes infinitely dense. The ratio m/M_h, which goes to zero in the continuum limit, can be viewed as a measure of non-locality in the regularized theory. An intricate hierarchy of length scales naturally arises. We speculate about the possible implications of these ideas for gravity and inflation.Comment: 27 pages plus 2 files of figure

Effective matter superpotentials from Wishart random matrices

We show how within the Dijkgraaf-Vafa prescription one can derive superpotentials for matter fields. The ingredients forming the non-perturbative Affleck-Dine-Seiberg superpotentials arise from constrained matrix integrals, which are equivalent to classical complex Wishart random matrices. The mechanism is similar to the way the Veneziano-Yankielowicz superpotential arises from the matrix model measure.Comment: 9 pages; v2: published versio
