Abstract: An appropriate understanding towards preference of small-scale dairy producers can improve technology adoption. The objective of this study was to understand potential, problem and need of small-scale dairy producers including farmer and his wife. The method used was modification of participatory rural appraisal (PRA) like participatory mapping to detect potential, and Preference ranking to understand problem and need priority. PRA applications were six times during April-September 2009 at central area and non-central area in Enrekang regency. Preference of farmer and his wife toward potential and problem were not different. Only feed technology need was different. Forage sources at central area were more diverse than non-central area but concentrate sources at non-central area were more than central area. Lack of knowledge for feed and concentrate formulation and nutritional requirements, less known of feed use, and low feed quality at dry season were the main problems at central area. At non-central area, lack of knowledge for preserving feed, lack of labour, and feed shortage at dry season were main problem faced by farmers. Knowledge improvement for local feed and complete-feed formulation are priority technology at central area. At non-central area, agricultural waste and forage preserving and complete-feed are needed by farmer.

Abstract: Calpastatin (CAST) is an indigenous inhibitor of calpain that involved in regulation of protein turn over and growth. The objective of this research was to identify genetic polymorphisms in the entire exon 6 of calpastatin gene in Indonesian local sheep. A PCR-SSCP method was carried out to identify genetic variation of CAST gene. In total 258 heads of local sheep from 8 populations were investigated, three groups of samples were Thin Tail Sheep (TTS) from Sukabumi, Jonggol, and Kissar. The rest samples were Priangan sheep (PS) from Margawati (Garut meat type) and Wanaraja (Garut fighting type) and Fat Tail Sheep (FTS) from Donggala, Sumbawa, and Rote islands. SSCP analysis revealed that three different SSCP patterns corresponded to three different alleles in the CAST locus (CAST-1, 2, and 3 allele) with five different genotypes. Genetic variation between local sheep populations were calculated based on genotypic and allelic frequencies. Most populations studied were polymorphic, with genotype frequencies of CAST-11, CAST-12, CAST-22, CAST-32, and CAST-33 were 0.286, 0.395, 0.263, 0.046, and 0.007 respectively. CAST-1 and 2 alleles were most commonly found in all populations with total frequency was 0.970, while CAST-3 was a rare allele 0.030 and only found in TTS population. Variation in the CAST gene could be used for the next research as genetic diversity study or to find any association between CAST polymorphism with birth weight, growth trait and carcass quality in Indonesian local sheep.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.33017
Abstract: In this work, the effect of heat input on the mechanical properties of low-carbon steel was studied using two welding processes: Oxy-Acetylene Welding (OAW) and Shielded Metal Arc Welding (SMAW). Two different edge preparations on a specific size, 10-mm thick low-carbon steel, with the following welding parameters: dual welding voltage of 100 V and 220 V, various welding currents at 100, 120, and 150 Amperes and different mild steel electrode gauges of 10 and 12 were investigated. The tensile strength, hardness and impact strength of the welded joint were carried out and it was discovered that the tensile strength and hardness reduce with the increase in heat input into the weld. However, the impact strength of the weldment increases with the increase in heat input. Besides it was also discovered that V-grooved edge preparation has better mechanical properties as compared with straight edge preparation under the same conditions. Microstructural examinations conducted revealed that the cooling rate in different media has significant effect on the microstructure of the weldment. Pearlite and ferrite were observed in the microstructure, but the proportion of ferrite to pearlite varied under different conditions.

International Journal of Astronomy and Astrophysics (IJAA) , 2015, DOI: 10.4236/ijaa.2015.53022
Abstract: In this paper we present astrophysical parameters of the very old open star cluster Berkeley 39 using 2MASS JHK data and observation of BV CCD photometry (V ~ 21.5 mag) in Johnson-Cousin filters. We have derived reddening, distance, metallicity and age etc. using two color diagrams in near-infrared and optical bands. We have found EB-V = 0.099 ± 0.02, EJ-H = 0.018 ± 0.001 and EJ-Ks = 0.016 ± 0.001 mag, and the distance modulus of (m-M) 0 = 13.24 ± 0.03 mag, which give a distance of 4.2 ± 0.04 Kpc, and the age of the cluster is 5.6 Gyr with metallicity; Z = 0.008 (obtained from fitting of the observed CMDs with Padova iso-chrones). The radius of the cluster obtained from the analysis of 2MASS data is equal 9.0 ± 0.13 arc minutes; it reflects that the cluster have large radius with new cluster center. Luminosity and mass functions have been investigated as well as the dynamical relaxation time of the cluster Berkeley 39.
Fetal ECG Extraction from Maternal Abdominal ECG Using Neural Network  [PDF]
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.25043
Abstract: FECG (Fetal ECG) signal contains potentially precise information that could assist clinicians in making more appro-priate and timely decisions during pregnancy and labor. The extraction and detection of the FECG signal from com-posite maternal abdominal signals with powerful and advance methodologies is becoming a very important requirement in fetal monitoring. The purpose of this paper is to illustrate the developed algorithms on FECG signal extraction from the abdominal ECG signal using Neural Network approach to provide efficient and effective ways of separating and understanding the FECG signal and its nature. The FECG signal was isolated from the abdominal signal by neural network approach with different learning constant value and momentum as well so that acceptable signal can be con-sidered. According to the output it can be said that the algorithm is working satisfactory on high learning rate and low momentum value. The method appears to be exceedingly robust, correctly isolate the FECG signal from abdominal ECG.

Abstract: This study evaluated the simple methods to improve the sorptional capability of polymeric sorbent to gold (III) ions. The polymeric sorbents have been synthesized by a chemical modification of dithizone phosphorchlorinated PB. The structure and composition of functional polymers are studied by IR spectroscopy, X-ray fluorescence analysis, the diffusion of optical spectroscopy, scanning electron microscopy, thermogravimetric and elemental analysis. It found that the obtained sorbents had porous crosslinked structure and did not dissolve in any organic solvents, solutions of inorganic acids and alkalines. The sorption properties of the syntesized polymer sorbents onto gold (III) ion in aqueous solutions have been studied. It is found that the adsorption effect of gold makes 85% - 90% and the equilibrium sorption capacity of polymer sorbent is 137 mg/g in acidic media. In order to improve sorption efficiency of sorbents to gold ions, the non-covalent immobilization of organic sulfur containing compound to the polymer matrix was carried out. The gold embedded polymer matrix was characterized by SEM, EDX, XRD and visible absorption spectroscopy. The obtained results indicated that the polymeric sorbent contained metallic form of zero-valent gold. It was found that the average particle size of elemental gold crystals was 28.31 nm.

Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.54031

Background: There is a progressive shift away from the use of forceps in favour of the vacuum extractor as the instrument of choice for operative vaginal deliveries. The overall objective of this is to improve safe motherhood by reducing the contribution of second stage of labour complications to maternal mortality and morbidity. Objective: This study was carried out to determine the incidence, indications, outcome and complications of Ventouse delivery in Aminu Kano Teaching Hospital, Kano, Nigeria. Materials and Methods: This was a retrospective study carried out at the Aminu Kano Teaching Hospital. The case notes of all parturients who had vacuum deliveries in the hospital within January 2008 to December 2012 were retrieved from the statistics unit of the hospital and analysed using SPSS. Results: 22,680 patients delivered in the hospital over this 5-year period. Ventouse was used on 210 occasions giving an incidence rate of 0.9%. One hundred and eighty (85.7%) had successful vacuum delivery. The failed extractions (14.3%) were delivered by caesarean sections. The mean age of the patients was 29.4 years. The mean parity was 2.2. Ninety (42.9%) were primipara while 120 (57.1%) were multipara. The commonest indication for the vacuum delivery was prolonged second stage of labour in 45.2% of cases. The commonest maternal complication was primary postpartum haemorrhage (9.5%). Foetal complication occurred in about 31% of vacuum deliveries, the commonest (18.1%), being cephalhaematoma. Conclusion: The incidence rate of vacuum delivery is low. Thus, active training in the art of vacuum assisted vaginal delivery is clearly needed during residency.

Abstract: The study was carried out to determine the influence of sweet potato peels and cashew nut shell supplemented with Ocimum gratissium leaves, using growth indices and blood constituents by goats. Eighteen goats with an average weight of 8.11 kg and aged between 8 and 9 months old were allotted to three dietary treatments with six animals per treatment in a complete randomized design. The compared diets which comprised combination of sweet potato peels and cashew nut shell with concentrate respectively were in different ratios which included diet I (30:25:45), diet II (25:30:45) and diet III (20:35:45). Each goat also received 8 grams of Ocimum gratissium leaves as supplement in the diet. The results showed that average feed intake (6.42 kg) and fed conversion ratio (2.15) were highest in diet I and significantly different from other diets. Diet II had the highest significant (P < 0.05) values in final body weight (12.01 kg), average total weight gain (3.89 kg), packed cell volume (29.46%), haemoglobin (10.96%), red blood cell (9.84 × 103/L), lymphocytes (56.01%), monocytes (1.06%), total protein (7.65 g/dl), albumin (3.58 g/dl), globulin (4.07 g/dl) and triglyceride (2.29 mmol/L). White blood cell (7.01 × 103/L), neutrophils (49.82%), cholesterol (42.34 mmol/L), creatnine (1.59 mg/dl) and urea (18.29 mg/dl) were (P < 0.05) best in diet III, whereas initial bodyweight, average daily weight gain, eosinophils and basophils were not significantly different (P < 0.05). It is concluded that diet II has the potential to enhance growth rate and blood constituents of goats.

Open Journal of Applied Sciences (OJAppS) , 2019, DOI: 10.4236/ojapps.2019.92007
Abstract: Low-cost adsorbents, Magnesium ferrite (MgFe2O4) nanoparticles were synthesized using three different types of fuel such as Urea, Oxalic acid, and Citric acid via sol-gel auto-combustion method. The prepared products were characterized by means of powder X-Ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR) and Field Emission Scanning Electron Microscope (FE-SEM). The influence of the fuel used on the morphology and the crystallite size of MgFe2O4 Nano products were studied. The results showed that Citric acid fuel produced pure MgFe2O4 with the smallest crystallite size average cluster = 13.53 nm. The synthesized sample was used for the removal of 99TcO4- anions from low level liquid waste under studied conditions. The different parameters affecting on the adsorption process using the batch method were studied. The results revealed that MgFe2O4 nanostructure has high removal ability of 99TcO4- from aqueous solutions (98.84%). The adsorption data are in good agreement with Freundlich and Pseudo second order isotherm models. The adsorption process was a chemisorption reaction additionally, the results of the thermodynamic parameters indicated that the adsorption of 99TcO4- on nanostructures was an exothermic and spontaneous process.
