Analisis Konsumsi Energi Rumah Tangga Perkotaan Di Indonesia: Periode Tahun 2008 Dan 2011

Urban Household Energy Consumption Analysis in Indonesia: Period of 2008 and 2011The goal of the study is to analyze the pattern and the change of urban household energy consumption and their determinant factors in Indonesia period of 2008 and 2011 using SUSENAS data of household budget survey. The concept of energy ladder and fuel stacking (multi fuel) are used to make a model of household energy consumption. The result of study shows that total energy consumption was increase in the period of 2008 and 2011. Coefficient of income elasticity toward both of modern and traditional energy consumption are positive, it means that there is rising consumption of energy along with the rising income. Household income is the main determinant factor of energy used by household besides other non-economic factors

Myoma in pregnancy and outcome after cesarean myomectomy

Background: The prevalence of leiomyoma is 30% to70% in reproductive women. In addition to causing menstrual disorders like menorrhagia, mass in abdomen, pain and it also negatively affect fertility and pregnancy outcome. Objectives of present study was to investigate the outcome in cases of pregnancy complicated by fibroids undergoing lower segment cesarean section (LSCS) in DM WIMS Medical College and Hospital, Wayanad, Kerala, where the prevalence of fibroids is high in reproductive women.Methods: Twelve cases of leiomyoma with pregnancy underwent LSCS with myomectomy following the delivery of the baby. The indications for myomectomy during LSCS taken into consideration were firstly the size of fibroids usually less than 5 cm, mainly single myoma complicating pregnancy and sites like sub serous and intramural. The suturing of the uterus was done using polyglycolic acid of size No. 1 and polyglycolic acid suture of 2 ‘0’ for closing the dead space and with good hemostasis the operation was completed. The indications for cesarean, the average operative time for surgery, the amount of blood loss, and postoperative complications like surgical site infections were noted and outcome recorded.Results: The time taken for surgery was about 45 minutes longer, average blood loss was approximately 300 ml to 500 ml more than for a routine LSCS. There was no surgical site infections or postpartum hemorrhage in any of the cases.Conclusions: Myomectomy with caesarean in selected cases with proper indications is safe and possible in selected cases. It avoids a second surgery with its associated morbidity

A full body musculoskeletal model based on flexible multibody simulation approach utilised in bone strain analysis during human locomotion

Load-induced strains applied to bone can stimulate its development and adaptation. In order to quantify the incident strains within the skeleton, in vivo implementation of strain gauges on the surfaces of bone is typically used. However, in vivo strain measurements require invasive methodology that is challenging and limited to certain regions of superficial bones only such as the anterior surface of the tibia. Based on our previous study [Al Nazer et al. (2008) J Biomech. 41:1036&ndash;1043], an alternative numerical approach to analyse in vivo strains based on the flexible multibody simulation approach was proposed. The purpose of this study was to extend the idea of using the flexible multibody approach in the analysis of bone strains during physical activity through integrating the magnetic resonance imaging (MRI) technique within the framework. In order to investigate the reliability and validity of the proposed approach, a three-dimensional full body musculoskeletal model with a flexible tibia was used as a demonstration example. The model was used in a forward dynamics simulation in order to predict the tibial strains during walking on a level exercise. The flexible tibial model was developed using the actual geometry of human tibia, which was obtained from three-dimensional reconstruction of MRI. Motion capture data obtained from walking at constant velocity were used to drive the model during the inverse dynamics simulation in order to teach the muscles to reproduce the motion in the forward dynamics simulation. Based on the agreement between the literature-based in vivo strain measurements and the simulated strain results, it can be concluded that the flexible multibody approach enables reasonable predictions of bone strain in response to dynamic loading. The information obtained from the present approach can be useful in clinical applications including devising exercises to prevent bone fragility or to accelerate fracture healing.<br /

Effects of Yucca schidigera extract on the growth performance, feed efficiency, body composition of common carp (Cyprinus carpio, Linnaeus 1758) and culture water quality

One of the important goals in the aquaculture industry is to increase fish production with the least stress from ammonia secretion. Yucca plant (Yucca schidigera) was composed of steroidal saponins, polysaccharides, and polyphenols, which have increase the intestinal flora activity to improving the digestive process, also great absorption capacity for harmful volatile compounds, such as ammonia and hydrogen sulfide. Therefore, the aim of this study was to evaluate the effects of different Yucca schidigera extract levels on the Cyprinus carpio growth, feed performance, body composition and culture water quality for 60 days. Experimental treatments were designed which include: T1 (control without extracts), T2, T3 and T4 treatments (containing 0.5, 1 and 1.5% Yucca extract respectively). In a completely randomized design, 360 Common carp fish with weight of 2.40±0.04 g and length of 5.47±0.05 cm were reared in twelve 40-L plastic tanks. Different levels of extract were sprayed on commercial food and consumed at 4 times daily. There was significantly higher final body weights in T4 (p<0.05) compared with control (T1) and other experimental treatments (T2 and T3). Similarly, significantly better (p<0.05) feed conversion ratio (FCR), 2.01±0.37 and protein efficiency ratio (PER), 0.17±0.01 was noticed in T4 compared to control (FCR 2.71±0.31 and PER 0.14±0.01). The biochemical composition of carcass had a significant difference between treatments (p<0.05). The body chemical composition analysis showed that the low levels of crude protein and the high levels of crude lipids in T4 treatment were 62.87±2.63% and 26.29±1.55%, respectively. The physical and chemical parameters were within the recommended range for C.carpio. The experiment treatments had the lowest amount of ammonia and the highest amount of nitrate compared to the control treatment in culture water. The results of this experiment showed that the use of Yucca extract can improve the growth, feed performance, body composition and the water quality of the common carp culture system

Antibacterial effect of Jordanian propolis and isolated flavonoids against human pathogenic bacteria

Propolis is a natural product widely consumed in folk medicine. The present study was carried out to investigate the antibacterial activity of Jordanian propolis, collected from two locations with two different dominant floras (Type1; Pine trees and Type ll; Oak trees). Zones of inhibition and minimum inhibitory concentrations (MICs) were determined on methicillin resistant Staphylococcus aureus (MRSA), multidrug resistant Escherichia coli and standard strains of both bacteria. Propolis Type I and Type II showed antibacterial activity against MRSA (MIC 4.69 and 18.75 μg ml-1, respectively). Crude propolis from Type I showed higher antibacterial activity than Type II against the tested bacteria. Three pure phenolic compounds (three flavonoids) namely, pinobanksin-3-O-acetate, pinocemberin and chrysin, were isolated from fractions I-2 and I-4, and screened in vitro for antibacterial activity. Pinobanksin-3-O-acetate and pinocembrin exhibited antibacterial activity especially against MRSA, while chrysin was only active against standard S. aureus. This is the first report that shows in vitro antibacterial activity of isolated flavonoids from Jordanian propolis against standard and resistant strains of E. coli and MRSA. Overall, results of this study highlight the important role of propolis botanical source on the antibacterial activity of such natural material which might affect its medical applications.Keywords: Antibacterial activity, human pathogens, flavonoids, propolis, methicillin resistant Staphylococcus aureus, Escherichia coliAfrican Journal of Biotechnology Vol. 9(36), pp. 5966-5974, 6 September, 201
