Influence of Source Propagation Direction and Shear Flow Profile in Impedance Eduction of Acoustic Liners

The acoustic impedance of liners is a key parameter for their design, and depends on the flow conditions, i.e., the sound pressure level and the presence of a grazing flow. The surface impedance of a locally reacting liner is defined as a local intrinsic property relating the acoustic pressure to the normal acoustic particle velocity at the liner surface. Impedance eduction techniques are now widely used to retrieve the impedance of liners in aeroacoustic facilities in the presence of a shear grazing flow. While surface impedance is intrinsic by definition, the educed impedance has recently been shown to depend on the direction of the incident waves relative to the mean flow. Different studies have investigated this issue by considering different acoustic propagation models used in the education process in the hope of matching the educed values. The purpose of the present work is to continue the previous investigations by evaluating the influence of the shear flow profile on the educed impedance, while considering a Bayesian inference process in order to evaluate the uncertainty on the educed values. The identified uncertainties were not able to totally account for the observed discrepancies between educed impedances

Improvement of Nutritional Value of Instant Noodles by Fortifying with Catfish (Pangasius Hypophthalmus) Flour

This study was intended to evaluate the nutritional value of instant noodlesfortified with catfish flour. Instant noodles were prepared from a mixture of wheatflour (50%), sweat potato flour (10%), egg (15%), salt (0,7%), water (23%),cooking oil (0,3%) and Carboxy Methyl Cellulose (1%). The noodles wereprepared by fortifying the mixture with catfish flour at a level of 0%, 5%, 10%,and 15 % respectively. Instant noodles was evaluated for sensory quality andproximate composition (moisture, protein, carbohydrate, and fat). The resultshowed that instant noodles fortified with 15% of catfish flour has the bestsensory and proximate quality. Moisture, protein, carbohydrate, and fat for theinstant noodles was 3,88%, 36,67%, 21,00%, and 9,03% respectively

Effect of White Oyster Mushroom (Pleurotus Ostreatus) on Consumer Acceptance of Dry Small Shrimp (Acetes Erythraeus) Nugget Products

This research aimed to determine the effect of white oyster mushroom onconsumer acceptance of shrimp nugget products. Dry shrimp used 400g weight byeach addition of different oyster mushroom consists of 4 levels ware, 0% (N0),25% (N1), 50% (N2), and 75% (N3) from the weight of dry small shrimp. Theresults showed that organoleptic test on prefered was N2 (200g). Based onproximate analysis of dry shrimp nugget with 200g (N2) white oyster mushroomaddition were significantly influence on water content (29.72%), ash (36.66%),protein content (19.06%), and crude fiber content (2.38%)

Understanding of the Renormalization Program in a mathematically Rigorous Framework and an Intrinsic Mass Scale

we show there exists a mathematically consistent framework in which the Renormalization Program can be understood in a natural manner. The framework does not require any violations of mathematical rigor usually associated with the Renormalization program. We use the framework of the non-local field theories [these carry a finite mass scale (\Lambda)]and set up a finite perturbative program. We show how this program leads to the perturbation series of the usual renormalization program [except one difference] if the series is restructured .We further show that the comparison becomes possible if there exists a finite mass scale (\Lambda), with certain properties, in the Quantum Field theory [which we take to be the scale present in the nonlocal theory]. We give a way to estimate the scale (\Lambda). We also show that the finite perturbation program differs from the usual renormalization program by a term; which we propose can also be used to put a bound on (\Lambda).Comment: 19 pages, a missing equation added,a reference added and a few typos correcte

Keragaman Morfofisiologi Tanaman Kelapa Sawit Di Lahan Gambut / Morphophysiology Performances of Oil Palm on Peat Land

Tanaman kelapa sawit (Elaeis guineensis Jacq.) sebagian besar ditanam di lahan gambut. Tujuan penelitian mengevaluasi morfo-fisiologi pertumbuhan dan hasil berdasarkan keragaan tanaman kelapa sawit varietas SJ2 umur 6 tahun. Penelitian dilakukan di Kabupaten Muara Enim, Sumatera Selatan, pada lahan gambut dengan kedalaman antara 2,5 sampai 4 meter, hemiks dan in land pada Mei 2012 sampai Januari tahun 2013. Penelitian menggunakan Rancangan Acak Kelompok, satu perlakuan. Perlakuannya adalah ketegakan tanaman kelapa sawit var. SJ2 umur 6 tahun berdasarkan nilai 0 sudut yang terbentuk antara batang dengan permukaan gambut, dengan ulangan sebanyak 2 kali. Perlakuan perbedaan kenampakan tegak batang, yaitu: tegak (900 ), agak miring (600 ≤ sudut < 900 ), sangat miring (450 ≤ sudut < 6 0 ), dan roboh (00 ). Hasil menunjukkan bahwa tanaman dengan keragaan tegak dan agak miring memiliki anak daun sempit, pelepah pendek dan sedikit dengan ILD rendah 2,53 dan 2,73, serta densitas populasi akar primer tinggi. Tanaman yang sangat miring dan rebah memiliki anak daun luas; ILD tinggi 6,15 dan 4,33; densitas luas area permukaan akar sekunder dan bobot kering populasi akar tinggi, tetapi densitas populasi akar primer rendah. Tanaman dengan keragaan yang tegak lebih mempunyai kualitas pertumbuhan yang lebih tinggi dibanding yang sangat miring maupun rebah, dengan konsentrasi Al daun 105,05 ppm maupun rasio N : P daun 13,95 yang rendah. Hasil TBS tertinggi 2,43 kg/tanaman/panen di tahun pertama pada tanaman dengan keragaan tegak

Analysis of Male Participation in Contraceptive USAge in Indralaya Mulya District Kecamatan Indralaya Ogan Ilir Regency in Year 2011

Background : Indonesia has 216,9 million number of people with 1,36% population growth rate. In order to restrict this rapid population increasing, Governmalet had done the construction oriented to the justice and gender equality in Family planning and Reproductive Health. One of the gender equality in family planning was male participation in contraceptive USAge. But, nowadays the gender equality in Indonesia is still dominated by women. Based on the data of UPTB KB Monthly Report Kecamatan Indralaya, male participation in contraceptive USAge in Kelurahan Indralaya Mulya was still bad. Because of that, this research aimed to know the male participation in contraceptive USAge. Method : Used analytic survey method with cross sectional study design. Sample in this research was male who have wife aged 15-49 years old which amounts to 82 people. The sampling technique used simple random sampling. Data analysis technique used univariate and bivariate with statistic test used Chi Square test. Result : Showed that from 7 independent variables, 5 variables were connected to male participation in family planning, education (pvalue = 0,001), knowledge (pvalue = 0,014), family planning services access (pvalue = 0,010), male family planning quality service (pvalue = 0,030) and male family planning image (acceptance) (pvalue = 0,008). Conclusion : Variables related to male participation in family planning are education, knowledge, family planning services access, male family planning quality service and male family planning image (acceptance) whereas variables which are not related are age and number of children
