Thermodynamic and Kinetic Studies for the Adsorption of Fe(III) and Ni(II) Ions From Aqueous Solution Using Natural Bentonite

In this study, the adsorption behavior of natural bentonite with respect to Fe(III) and Ni(II) has been studied in order to consider its application to purity metal finishing wastewaters. During the adsorption process, batch technique is used, and the effects of pH, bentoite amount, temperature, heavy metal concentration, bentonite treatment (calcinations of natural bentonite at 700°C, washing by deionized water to remove the excess salt from bentonite surface), and agitation time on adsorption efficiency are studied. The washed and calcined bentonite samples were labeled by WB and CB, respectively. The pH-dependence of Fe(III) and Ni(II) sorption on the bentonite is significantly more noticeable, indicating a major contribution of surface complexation at the edge sites. It was determined that adsorption of Fe(III) and Ni(II) is well fitted by the second order reaction kinetic. Furthermore, the sorption rate of Fe(III) was higher than the sorption rate of Ni(II). Adsorption of Fe(III) and Ni(II) on NB appeared to follow Langmuir isotherm. In addition, calculated and experimental adsorbed amounts of Fe(III) by the unit NB mass are very higher than Ni(II). The paper also discusses the thermodynamic parameters of the adsorption (the Gibbs free energy, entropy, and enthalpy). Our results demonstrate that the adsorption process was spontaneous and endothermic under natural conditions. Also the adsorption capacity of bentonite for Fe(III) Ni(II) and increases with increased bentonite dose. According to the equilibrium studies, the selectivity sequence can be given as Fe(III) > Ni(II). The adsorbed amount of Fe(III) and Ni(II) on washed bentonite (WB) were very higher compared to NB and CB. Our results show that bentonite could especially WB be considered as a potential adsorbent for Fe(III) and Ni(II) removal from aqueous solutions.
Solubility of isobutane and propane in polyethylene at high temperatures and low pressures

A novel procedure was developed to measure the solubility of isobutane and propane in both low and high-density polyethylene at temperatures to 500°F (260°C) and vapor pressures from 1 to 1500 torr (33 psia). These measurements represent the first known solubility measurements at these combined extremes of pressure and temperature. Excellent agreement was found when our data were extrapolated to higher pressures and compared with data from another source. In the temperature and pressure regions of interest in this work, the linear isotherms were fit with a form of the Flory–Huggins equation. With the equation in that form we can now estimate the ratio of solubilities of two solutes in a given polymer from pure solute data only. We can also predict the absolute solubility of nonpolar solutes in polyethylene at various temperatures and pressures using only critical temperatures and acentric factors of the solutes.
Black soybean tempeh and purple sweet potato improve sperm quality in streptozotocin-induced diabetic rats

Background and Aim: Hyperglycemia increases advanced glycation end-product (AGE) production, and the activity of receptor for AGE (RAGE) in testis, which leads to testicular histopathological damage and infertility. This research investigated the effect of black soybean tempeh (BST), purple sweet potato (PSP), and its combination on AGE and RAGE expression and spermatozoa quality in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: The rats were given high-fat diets for 5 weeks, then were injected intraperitoneally with multiple low doses of STZ (30 mg/kg body weight). Diabetes mellitus (DM) rats were divided into seven groups: DM, DM+glibenclamide, DM+BST, DM+PSP, and DM+combination of BST and PSP in ratio 1:3, 2:2, and 3:1 as C1, C2, and C3, respectively. The rats were treated for 30 days. Testicular AGE and RAGE expression and spermatozoa quality were measured. Results: The combination of BST and PSP significantly decreased AGE and RAGE expression in testicular organs and improved spermatozoa quality compared to the normal group. Conclusion: The combination of BST and PSP can be used as future alternatives to improve spermatozoa quality in DM patients.
EFFECT OF BREWER'S DRIED GRAIN AND YEAST CULTURE ON GROWTH PERFORMANCE AND CARCASS TRAITS OF BROILER CHICKS

The present study was performed to investigate the effect of dietary brewers dried grain (BDG) and 2 levels of yeast culture (YC) (Saccharomyces cerevisiae) on growth performance carcass traits some dietary measurements and economical efficiency of broiler chicks during 1-6 weeks of age under Egyptian conditions (15 October 30 November 2014) where the ambient temperature ranged between 20 to 26 Co. A factorial design (5 × 2) arrangement was performed included five levels of BDG (0, 3, 6, 9 and 12%) and two levels of YC (0 and 0.5 g \kg diet). The analysis of variance of the obtained results show a significant (P≤0.01) effect on live body weight (LBW) at 6 weeks of age, body weight gain (BWG) through 3-6 weeks of age and during 1-6 weeks of age. There was a significant linear reduction in LBW and BWG as the BDG increased (P≤ 0.01). There is a significant difference (P≤0.05) between diet containing 12% BDG and other diets for LBW and body weight gain during the whole experimental period (1-6) weeks of age. This diet have the lowest LBW and BWG. It could be noticed that, LBW and BWG during all different experimental periods were not significantly affected by different levels of YC. Also, interactions between BDG and YC levels were not significant (P≤0.05) on LBW at 6 weeks of age and BWG through (1-6) weeks of age. Results obtained in this study showed that, levels of BDG did not affect (P≤0.05) average feed consumption through all different experimental periods whereas, the feed gain ratio (FCR) significantly increased (P≤0.05) by increasing levels of BDG to 12%. The best value of FCR was 2.13 in the group of birds fed diet with 9% BDG. The present results did not show any significant effect on all carcass characteristics studied due to different dietary BDG and YC levels or their interactions, except giblets percentage, which was significantly (P≤0.01) affected by BDG levels and the interaction between BDG and YC levels. In conclusion, the results of this study indicated that, taking body weight gain, feed conversion and economical efficiency, the dietary level of 9% BDG with or without yeast culture supplementation may be the best percentage till 6 weeks of age. While yeast culture did not affect on the performance and carcass traits.
Blood compatible biomaterials: Hydrophilicity vs. hydrophobicity

A tendency towards unification of adsorption properties of hemocompatible hydrophilic and hydrophobic surfaces within the first minutes of contact with protein was demonstrated. Nevertheless the change of adsorption properties of blood compatible hydrophilic surface after passivation with proteins is much less in comparison with the one for blood compatible hydrophobic surface.
Global Green Deal: International Cooperation on Net-Zero Carbon Emission

We develop and estimate an integrated model of climate and the world economy to study international cooperation on net-zero carbon emission among sixteen geographic regions. We find that achieving net-zero emission by mid-century reduces global social welfare loss by up to 35%, accounting for the emission reduction cost. However, we show that the economic benefit of free-riding may entice each region to quit the cooperation at the early stage. We demonstrate that trigger strategies are not effective in stabilizing the cooperation and would quickly lead the world to the punishment phase. We also demonstrate that monetary transfers can improve the cooperation outcome but are not able to support net-zero emission. These results suggest that global effort on achieving net-zero carbon emission by mid-century is desirable, but the required international cooperation may be difficult to sustain.
Service Quality and Queue

While active buyers can bring a firm stable income, their perceptions of service quality can help the firm improve its service. This investigation identifies five factors that influence service quality for queuing customers. This investigation also identifies the causality relationships among five factors that influence service quality. Tangibility and responsiveness should be foci for a service company hoping to change customer perceptions to service quality. Tangibility directly enhances responsiveness and assurance. Tangibility indirectly enhances reliability and empathy. Moreover, responsiveness enhances assurance and empathy. Responsiveness directly enhances reliability. Through enhancing responsiveness and tangibility, customers should develop good feelings regarding service quality.

Automated Extraction of Time References From Clinical Notes in a Heart Failure Telehealth Network

Heart failure (HF) is one of the biggest concerns for health care systems in developed countries. To support the long-term treatment of HF patients, the Austrian Institute of Technology implemented a HF telehealth network called “HerzMobil”. While most data within this network are stored in a structured format, health care professionals can also communicate via clinical notes in free text format. These notes are hardly ever analyzed automatically, even though a large number contains valuable information for the patient's treatment process. With currently more than 20,000 notes stored in the system, an automatic approach is beneficial to spare manual screening time. One important step in this process concerns the extraction of time references from the notes. This information could, for example, be used to match the time references with events from the same note. Therefore, two Python scripts were developed to: extract time references from the notes (Script A) and subsequently calculate the corresponding dates (Script B). Script A was compared to an already existing Python library and achieved superior results for all calculated key figures. The time calculation algorithm of Script B achieved an accuracy of 75.34%. These scripts could be implemented in the HerzMobil network to provide additional information for the treatment process and further improve the telehealth system.
Antiurolithiatic effect of Cymbopogon Proximus, Alhagi Maurorum, on Sulfadimidine induced urolithiasis in male New Zealand rabbits

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.
Biodegradation of red 40 dye by the mushroom Pleurotus sp florida

A study was made of the capacity of the mushroom Pleurotus florida to biodegrade red 40, a dye used in foods. Mycelia grown in nutrient-rich and poor liquid mediums were used in different concentrations of dye and with various pH. Spectrophotometric readings indicated that the dye had biodegraded in concentrations of 1.10-5 and 2.10-5 Mol.dm-3, with the best results obtained at a pH of 4.5. It was also found that the mycelia grown in both nutrient-rich and nutrient-poor mediums presented red 40 biodegrading activity.
Conditions for Aeronomic Applicability of the Classical Electron Heat Conduction Formula

Conditions for the applicability of the classical formula for heat conduction in the electrons in ionized gas are investigated. In a fully ionised gas ( V(sub en) much greater than V(sub ei)), when the mean free path for electron-electron (or electron-ion) collisions is much larger than the characteristic thermal scale length of the observed system, the conditions for applicability break down. In the case of the Venus ionosphere this breakdown is indicated for a large fraction of the electron temperature data from altitudes greater than 180 km, for electron densities less than 10(exp 4)/cc cm. In a partially ionised gas such that V(sub en) much greater than V(sub ei) there is breakdown of the formula not only when the mean free path of electrons greatly exceeds the thermal scale length, but also when the gradient of neutral particle density exceeds the electron thermal gradient. It is shown that electron heat conduction may be neglected in estimating the temperature of joule heated electrons by observed strong 100 Hz electric fields when the conduction flux is limited by the saturation flux. The results of this paper support our earlier aeronomical arguments against the hypothesis of planetary scale whistlers for the 100 Hz electric field signal. In turn this means that data from the 100 Hz signal may not be used to support the case for lightning on Venus.
Control of Reactivity in C−H Bond Breaking Reactions on Oxide Catalysts: Methanol Oxidation on Supported Molybdenum Oxide

Oxidation of organic substrates on metal oxide catalysts can be viewed as entailing a transfer of electrons from the organic moeity to the catalytic center, and is expected to involve the electron-accepting levels in the metal center. This investigation deals with the study of the electron-transfer processes associated with the C−H bond breaking reaction in adsorbed methoxide species in the course of methanol oxidation on supported MoO3. It is shown that the activity of a series of catalysts duly correlates with the unoccupied density of electronic states of the parent metal oxides. The unoccupied levels are probed with near-edge X-ray absorption spectroscopy (NEXAFS). The particular system chosen for study is that of methanol oxidation on supported molybdenum oxide, a reaction in which C−H bond breaking is rate-determining. The findings of this study are in good agreement with the known facts about the reaction and allow a deeper understanding of various reported effects. For example, the positive relati.
Intro to IE: Project Proposal

I will be conducting a novel application of entity recognition, entity typing, and relation mining for the task of classifying moral rhetoric in a large corpus of annotated Tweets. In a recent paper, Lin et al. (2017) conduct “Entity linking" to supplement established document classification methods to predict a Tweet’s five moral labels. These moral labels, which are theoretically derived from Moral Foundations Theory (see Graham et al., 2013, for a synopsis), are a set of binary labels that apply at the document level. Each label, when active, signifies that a given “moral concern" is used by the writer of the particular text. There are five labels, corresponding to the five moral foundations: fairness, care, authority, loyalty, and purity. In Lin et al. (2017), the authors link entities in Tweets and link them to an external Knowledge Base (Wikipedia) and append the text of the linked entities’ abstracts to the document. They achieve superior performance using this method, in comparison to purely text-based methods. In my project, I propose to improve this classification in two ways: (1) In terms of classification performance; (2) In terms of explainability. In this field, a key element of any predictive system is the ability to provide “reasoning" for each prediction, or a “trail of evidence" which influences the learner’s decision. Such information can facilitate collaboration between NLP researchers and domain experts, allowing the latter to design schema for future IE given the evidence provided to them in text classification. The method I will be using for classification is an attention-based LSTM (e.g. Wang et al., 2016). To form a coherent set of features which offers explainability in the form of entities (and their types) rather than just words, I propose to conduct distantly-supervised entity recognition and typing in the style of Ren et al. (2015). This will supplement traditional features in text classification (word and character n-grams, word embeddings, syntactic feature mining). In terms of the knowledge bases I will use to conduct distant supervision of the entity recognition and typing, I will use both established (i.e. Wikipedia) KB as well as less traditional, more specialized schema. This latter category of KB include actorand eventontologies in the political science community, notably CAMEO (Schrodt et al., 2008). Additionally, I have been working on developing a schema for structuring “political objects", including persons, groups, events, and concepts, which will be applied at later stages of the project, time allowing. The data I am using for this project is a set of roughly 30,000 annotated Tweets. Each Tweet has multiple annotations for each of the 5 moral foundations. Evaluation will be done by comparing classification metrics (precision, recall, F-1, and accuracy) between several baselines and the proposed method. Those methods will be:
Magnetic Ferroelectrics Bi,Pb-3$d$ Transition Metal Perovskites

Submitted for the MAR06 Meeting of The American Physical Society Magnetic Ferroelectrics Bi,Pb-3d Transition Metal Perovskites MASAKI AZUMA, KAZUHIDE TAKATA, TAKASHI SAITO, YUICHI SHIMAKAWA, MIKIO TAKANO, Inst. Chem. Res., Kyoto Univ., SEIJI NIITAKA, Mag. Res. Lab. , RIKEN, ALEXEI BELIK, ICYS, NIMS, SHINTARO ISHIWATA, Dept. Appl. Phys., Waseda Univ. — Magnetic ferroelectrics attract much attention because of the possible application for the memory device and the fascinating coupling between magnetic and dielectric properties. A classical way to obtain a magnetic ferroelectric is to locate Bi3+ or Pb2+ions and a magnetic transition metal ion on A and B sites of perovskite structure. The 6s2 lone pair and the strong covalent character of Bi(Pb)-O bonds stabilize a noncentrosymmetric distorted structure. For example, BiFeO3 and BiMnO3 are established antiferromagnetic and ferromagnetic ferroelectrics, respectively. We have studied structure, magnetic and electric properties of BiMO3 with M=Cr, Co and Ni and PbVO3 stabilized by high-pressure synthesis. BiCrO3 is an antiferromagnetic ferroelectric with BiMnO3 type structure. BiCoO3 and PbVO3 are found to have tetragonal PbTiO3 type structures with expected polarizations of ∼100μC/cm2. BiNiO3crystallizes in a triclinic structure where disproportionation into Bi3+ and Bi5+ takes place. We have also succeeded in preparing a designed ferromagnetic ferroelectric double provskite Bi2NiMnO6. In this compound, NaCl type ordering of Ni2+ (eg) and Mn 4+ (t2g) leads to ferromagnetism with TC=140 K. Masaki Azuma Inst. Chem. Res., Kyoto Univ.
