    Binodal data and the ternary liquid–liquid equilibria (LLE) was experimentally determined at 298.15 K for hydrophilic alcohols (1-propanol or 2-propanol) + salts (Na2SO4, (NH4)2SO4 or NH4NO3) + water systems. The salting-out and the phase-forming abilities of the salts and alcohols for the investigated ATPSs were discussed. The salting-out abilities of the investigated salts follow the order Na2SO4 > (NH4)2SO4 > NH4NO3, which can be indicated by the location of the binodal curves plotted in mass fraction, the effective excluded volume (EEV), the salting-out coefficient (Ks), the size of the ions, and the Gibbs free energy of hydration of the ions. The phase-separation ability of the studied hydrophilic alcohols was discussed on the basis of the dielectric constant and boiling point of the alcohols. The results show that the phase-separation capability of the system consists of different hydrophilic alcohols in the order: 1-propanol>2-propanol. Furthermore, the binodal curves of the studied systems were satisfactorily correlated by a nonlinear equation with four parameters. The reliability of the calculation method and the corresponding LLE data was successfully proved by the Othmer-Tobias equation and the Bancroft equation

    Introduction: Oketani massage and oxytocin is one of the breast care methods that do not cause pain. Massage can stimulate oketani pectoralis muscle strength to increase milk production and make the breasts become more soft and elastic so meumudahkan baby to suck milk. Massage oketani will also provide a sense of relief and an overall comfortable on respondents, improving the quality of breast milk, to prevent mastitis and nipple blisters and can fi x / reduce lactation problems caused by putting a fl at (fl at nipples), nipples that enter into (inverted). Method: This research was a quasi experimental with post test only design. Result: The results showed that there are different breastfeeding frequency, frequency of bowel, bladder frequency of respondents who do massage and oxytocin oketani. Discussion: one milk production assessment is to assess the frequency and volume of urine bladder baby. Normal babies will urinate 6-8 times a day, with a clear yellow color of urine is urine volume between 30-50 mg daily. This result is consistent with research conducted by Budiarti (2009) and Mardianingsih (2010) which states that the milk production can be judged from the frequency of micturition babies as many as 6-8 times a da

    Papua is well-known for its medicinal plants. However, several of them are not well documented yet. Numerous efforts have recently been addressed to record medicinal plants in different parts of Papua. This study aimed to identify medicinal plants in the Inamberi Research Station of Manokwari, West Papua Province. All plant species grown in the research station were listed and documented. The method used in this study was the observation method with survey techniques. Literature reviews were performed to identify the medicinal plants that were generally used by the local people of Papua. The conservation status of medicinal plants was derived from the IUCN red list website. The total medicinal plants grown in the research station were about 43 species, dominated by Euphorbiaceae and Moraceae families. Trees were the dominant medicinal plants. Medicinal plants in the research station can treat various diseases and some of them can cure more than one disease. Local people of Papua generally utilize leaves as medicinal plants. The utilization of medicinal plants was simple: boiling and drinking, directly eating it, chewing and attaching it to the wounds, and rubbing it on the skin. The conservation status of medicinal plants was categorized as low risk. However, concern should be given to Pterocarpus indicus that has been categorized by IUCN as an Endangered species. Ex situ and in situ conservation are required to protect this specie

    Abstract: In this study, ten whey samples collected from dairy industries in Rasht (Iran). Five lactose fermentative yeasts strains (designated A1 to A5) were isolated. Beta-galactosidase activity in the yeast strains showed that strain of Kluyveromyces marxianus designated as A2 had highest enzyme activity (up to 9012 EU/mL) and the most SCP production from whey with the yield of 12.68 g/L. Ammonium sulfate as nitrogen source had an increasing effect on biomass yield up to 30%. Crude fiber, lipids, carbohydrates and ash content of isolate dry cells were found to be 4.9, 7.23, 33.19 and 14.05%, respectively. The true protein content based on nitrogen fractionation procedure was 29.25%. The yeast biomass recovering by ultrafiltration reduced the total COD to 96.26% of its initial value in the raw whey

    The transport of p-nitrophenol (PNP) through a bulk liquid membrane (BLM) was investigated to evaluate the effect of different experimental conditions on PNP partitioning behavior. The influence of solvent type, different salts in feed phase, the feed phase pH and PNP concentration in feed phase on transport efficiency of PNP through the BLM were studied. The results indicated that the highest removal efficiency of PNP was observed for 80 % xylene + 20 % toluene as liquid membrane, Na2SO4 as salt in feed phase, in the acidic feed phase and in 150 min. The effect of initial concentration of PNP on the efficiency of the separation PNP showed that the increase in initial concentration up to 350 ppm had positive effect, and more than 350 ppm had negative effect on the PNP removal behavior. Also, pertraction in BLM systems were described by a kinetic model of two consecutive irreversible first order chemical reactions.

    A core business in the fashion industry is the understanding and prediction of customer needs and trends. Search engines and social networks are at the same time a fundamental bridge and a costly middleman between the customer’s purchase intention and the retailer. To better exploit Europe’s distinctive characteristics e.g., multiple languages, fashion and cultural differences, it is pivotal to reduce retailers’ dependence to search engines. This goal can be achieved by harnessing various data channels (manufacturers and distribution networks, online shops, large retailers, social media, market observers, call centers, press/magazines etc.) that retailers can leverage in order to gain more insight about potential buyers, and on the industry trends as a whole. This can enable the creation of novel on-line shopping experiences, the detection of influencers, and the prediction of upcoming fashion trends. In this paper, we provide an overview of the main research challenges and an analysis of the most promising technological solutions that we are investigating in the FashionBrain project

    All-sky Search for High-Energy Neutrinos from Gravitational Wave Event GW170104 with the ANTARES Neutrino Telescope

    Full text link
    Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4th^{\textrm{th}}, 2017. An all-sky high-energy neutrino follow-up search has been made using data from the ANTARES neutrino telescope, including both upgoing and downgoing events in two separate analyses. No neutrino candidates were found within ±500\pm500 s around the GW event time nor any time clustering of events over an extended time window of ±3\pm3 months. The non-detection is used to constrain isotropic-equivalent high-energy neutrino emission from GW170104 to less than 4×1054\sim4\times 10^{54} erg for a E2E^{-2} spectrum
