The purpose of this research study was to develop an advanced two-dimensional "processoriented" numerical water quality model for Brewster Lake that incorporates the physical, chemical and biological interactions that occur within the lake. The study included measuring and obtaining the basic physical, chemical, and biological characteristics of the lake to develop the model and appropriate initial and boundary conditions. Two rounds of measurements, one in the beginning of June and one in the end of July 2013, of the physical and chemical variables were conducted and were used to develop and calibrate the model. A hydrodynamic analysis of the lake's watershed was completed using modeling software (TR-55) and data collected from a HOBO data logger. The advanced model was then developed and coupled with the dissolved oxygen model for Brewster Lake that was developed by Argueta and Aljobeh during the summer of 2012. A set of "process-oriented" water quality mathematical equations, which include chemical and biological interactions, were programmed into sophisticated multi-physics finite-element based software, COMSOL, to solve the coupled mathematical models. A numerical model consisting of ten coupled differential equations combined with appropriate initial and boundary conditions was developed to predict the water quality of Brewster Lake and aid in the decision-making related to the management and planning of the lake and its watershed. The simulation results were compared with actual measurements and predictions of water quality data published in studies conducted on similar-size lakes in similar locations. This study is to be continued to develop a dynamic water quality model that will have the ability to predict water quality parameters of Brewster Lake for different nutrient loading scenarios. The advanced model has the ability to predict the spatial and temporal water quality of Brewster Lake in response to changes in organic, nitrogen, and phosphorous loadings. INTRODUCTION Water quality modeling has been used for many years to simulate a multitude of pollutants in a variety of waters. The first round of engineers and scientists mainly used models based on steady-state input-output mathematical equations (Vollenweider's, 1975 and Dillon and Rigler, 1974). However, such models have proved to be overly simplistic, in part because they tend to ignore the chemical and biological interactions in the lake. To improve upon the early "dataoriented" models, "process-oriented" water quality models now have a more explicit mechanistic basis and include the chemical and biological interactions (Jorgensen, 1997; Reckhow and Chapra, 1999). Many researchers have improved upon the mechanistic lake water quality models in the last twenty years (Wool et al., 2006; Chen et al., 2002; Omlin et al., 2001a;


Two important issues must be made clear in the context of the development of psychology in Mexico. Psychology in general and applied psychology in particular are relatively new and fast-growing fields of study in this country. In 1940, there were only six students registered in the Department of Psychology at the National University of Mexico (the largest institution both for teaching and research in this country), and the first research papers in what at the time could be considered applied psychology appeared in the 1950s (e.g. Dias-Guerrero, 1952, on the mental and social health of Mexicans living in the cities; and Gomez-Robleda, 1959, on industrial psychology).

A typical introductory neuropharmacology course required of PharmD students is likely to faithfully follow standard texts, with minimal coverage of basic or clinical neuroscience. This approach does not encourage class attendance or participation, as the students may be bored with predictable lectures or may realize that all information to be tested on is in the textbook. The instructor can increase student attendance and interest by occasionally including clinical case studies or anecdotes, cultural references, and references to current events that pertain to a drug or receptor discussed. Recent but well documented "cutting edge" research findings, which may include magnetic resonance images of a neurological disorder or of a drug occupying a brain site, intrigue the students and stimulate active learning. These "digressions" into basic and clinical neuroscience occupy only a few minutes of lecture time per week, yet visibly boost student learning and enjoyment of the course.


We read with interest Feltmate and colleagues' article reporting follow-up in patients with molar pregnancy. They observed that despite the potential risk for these women to develop persistent trophoblastic tumor and choriocarcinoma, more than one third (37%) do not achieve the recommended follow-up. It is worrisome that despite the existence of follow-up recommendations that highlight the importance for these patients to receive a complete follow-up, so many do not complete it. However, few would deny that current protocols (6–12 months) are restrictive and imply important medical and social costs (medical visits, serum –human chorionic gonadotropin [ -hCG] tests, time lost from work) as well as cause women anxiety about the risk of relapse. Therefore, we fully support Feltmate and collaborators' comments that efforts should be made to reduce this period. Further to this, it may be of interest to consider that genetic constitutions for both complete and partialhydatidiform moles may potentially define women who are at an increased risk to develop persistent trophoblastic tumor. Complete hydatidiform moles have two genetic origins (homozygous or heterozygous), and it has been suggested that heterozygous moles may have a more aggressive behavior. This issue is controversial, and experience in this field is still limited given the small number of published cases. To provide more insight, we conducted a systematic review of the published reports to date, and our results suggest that heterozygous moles have a more aggressive outcome than their homozygous counterparts (Figure 1). Triploid partial hydatidiform moles also have two different genetic compositions and are either paternally derived (diandric) or maternally derived (dyginic), but it is still unknown if they have different malignant potentials. In a study of 3000 patients after partial hydatidiform moles, three developed a choriocarcinoma and all were paternally derived. The genetic constitution of molar pregnancy could define high-risk groups of women who require long-term follow-up and low-risk groups who probably need no follow-up once an undetectable hCG level is achieved. We encourage centers for trophoblastic diseases with a large number of cases to initiate studies to optimize the current follow-up recommendations, which probably could improve women's compliance.


As a reviewer I found the comment piece by Peter Birchenall and Alan Parrish on revising the system of reviewing journals very interesting — 'Journal reviewers and reviews: should the system be revised?' (Vol 12(13): 773). However, I was a little surprised at some of their comments and was not entirely sure what they were actually asking for, or indeed as to why.


High voltage interfaces are broadly used in many IC applications like motor control, power management a nd conversion, LCD panel drivers and automotive system s. Because the high voltage IC's are typically used in severe applications IC designers need to protect their circuits to a stead y growing list of requirements. In this paper we present an overview of the ESD, EOS and latch-up requirements and compare the perfo rmance of different on-chip ESD protection approaches. The pa per introduces a newly developed protection device with a high holding voltage for absolute latch-up immunity.


accuracy is the prime essential in roentgen therapy. It tends to prevent over-dosage and under-dosage. The dangers of over-dosage are constantly in our minds, but the dangers of under-dosage have been given slight attention. Over-dosage may result in permanent injury to the patient but under-dosage may take away his only chance for life. In this country, the great majority of roentgen-ray treatments are given, and must continue to be given, by roentgenologists whose offices are equipped with 10-inch transformers and Universal tubes. For some years at least, delicate and accurate measuring instruments will not be in common use. Since the degree of accuracy in roentgen therapy can be considerably increased by limiting the number of variable physical factors, the three combinations of factors, called, for convenience, Technics I, II, and III, as shown in Table I, are suggested as a basis for a simple routine technic. Variations in physical factors can affect only intensity, hardness, and distribution of the ...

Objective To investigate the effect of the Yiqi Huoxue decoction on CTGF and PDGF-B of chronic renal failure(CRF) rats.Methods Rat models of CRF were established by feeding Adenine.All the rats were randomly divided into six groups:the normal group,the model group,the high dosage Yiqi Huoxue decoction group,the medium dosage Yiqi Huoxue decoction group,the low dosage Yiqi Huoxue decoction group and the losartan group.After 8 weeks,levels of serum creatinine(SCr),blood urea nitrogen(BUN),triglyceride(TG),cholesterol(CHO),plasma albumin(ALB),and hemoglobin(HB) were determined.In addition,the results of pathology were found by HE and the expressions of CTGF and PDGF-B were determined by the immuohistochemical method.Results Compared with the model group,levels of SCr,BUN,and CHO in the Yiqi Huoxue decoction groups and the losartan group were decreased,while levels of ALB and HB were increased(P0.05).Pathological results of the Yiqi Huoxue decoction groups and the losartan group were better than those of the model group,and those of the high dosage Yiqi Huoxue decoction group were the best.Expressions of CTGF and PDGF-B in the Yiqi Huoxue decoction groups and the losartan group were decreased compared with the model group.Conclusions Yiqi Huoxue decoction can efficiently decrease SCr,BUN,and CHO levels and increase ALB and HB levels,reduce pathological injury and the CTGF and PDGF-B expressions,and postpone the aggravation of renal function.


The development of tools for the generation of 3D city models started almost two decades ago. From the beginning, fully automatic reconstruction systems were envisioned to fulfil the need for efficient data collection. However, research on automatic city modelling is still a very active area. The paper will review a number of current approaches in order to comprehensively elaborate the state of the art of reconstruction methods and their respective principles. Originally, automatic city modelling only aimed at polyhedral building objects, which mainly reflects the respective roof shapes and building footprints. For this purpose, airborne images or laser scans are used. In addition to these developments, the paper will also review current approaches for the generation of more detailed facade geometries from terrestrial data collection.


This paper describes an algorithm to decompose speech into tonal, transient, and residual components. The algorithm uses an MDCT-based hidden Markov chain model to isolate the tonal component and a wavelet-based hidden Markov tree model to isolate the transient component. We suggest that the auditory system, like the visual system, is probably sensitive to abrupt stimulus changes and that the transient component in speech may be particularly critical to speech perception. To test this suggestion, the transient component isolated by our algorithm was selectively amplified and recombined with the original speech to generate enhanced speech, with energy adjusted to be equal to the energy of the original speech. The intelligibility of the original and enhanced speech was evaluated in eleven human subjects by the modified rhyme protocol. The word recognition rates show that the enhanced speech can provide substantial improvement in speech intelligibility at low SNR levels (8% at -15 dB, 14% at -20 dB, and 18% at -25 dB)


The gasification reactivity of raw coal,filter cake and the slag in demister from an industrial gasification plant was investigated with steam and carbon dioxide as the gasification agent.The initial structure and surface characteristic of the samples were analyzed by scanning electron microscope and adsorption apparatus.The results show that the gasification reactivity of the raw coal is better than that of the slag in demister,while the gasification reactivity of the slag is similar to or a bit better than that of filter cake,which is mainly attributed to the extraordinary difference of surface and internal structure of these three samples.As a result of different reaction mechanism with steam and CO2,the gasification reactivity of the samples with steam is about 3 times higher than that with CO2.


This paper describes an extensive monitoring project which collected end-use electric power, city gas consumption and ambient and room temperature measuring at thirty minute intervals over one year for 40 residential houses in a newly developed town in the suburb of Kyoto and Nara. The primary purpose of this project is to estimate the potential for energy saving and to find effective ways to achieve energy saving in the residential sector in Japan. Better understanding ofthe nature ofenergy demand in residential houses is essential in order to identify savings opportunities at the end use level. The monitoring system used was completely automatic, and the data for the period from Oct. 1998 to Nov. 1999 have been acquired successfully. The measured data were separated into end-use purposes such as the demand for space cooling and heating, hot water and cooking. Daily load curves for each end-use have been estimated from the measured data. In this paper, the project will be described in detail, and the present state of end-use energy demand in the relatively new typical residential houses in Kansai region of Japan, will be described.

Editors of Slavonic and Slavonic–Romanian text can make use of a large variety of tools (fonts, physical and virtual keyboard layouts, word processors, operating systems) for transcribing and digitizing these texts in a uniform manner. The uniformity of the transcripts is based on Unicode standardization. Our study aims at explaining the place of Slavonic in Unicode and at briefly describing the most accessible tools. To this end, we shall describe the working tools from a historical and functional perspective and then provide examples in which those tools can be or have already been used to obtain a more accurate transcript. The user can choose from the existing methods and tools according to his/her purposes, needs and means. A better understanding of technical data can reduce the working time, improve transcription, accelerate learning times and generally make an editor's work much easier.

Previous work has shown that the soluble murine BMPR1A–fusion protein (mBMPR1A‐mFc) binds to BMP2 and BMP4 with high affinity, preventing downstream signaling. Further, treatment of intact and ovariectomized mice with mBMPR1A‐mFc leads to increased bone mass, and improved bone microarchitecture and strength, via increased bone formation and reduced resorption. In this study, we tested the effects of mBMPR1A‐mFc on disuse‐induced bone loss caused by 21 days of hindlimb unloading (HLU) via tail suspension versus cage controls (CONs). Adult female C57BL/6J mice (12 weeks old) were assigned to one of four groups (n = 10 each): CON‐VEH; CON‐mBMPR1A‐mFc; HLU‐VEH; and HLU‐mBMPR1A‐mFc. Mice were injected subcutaneously with VEH or mBMPR1A‐mFc (4.5 mg/kg, 2×/week). Leg BMD declined in the HLU‐VEH group (–5.3% ± 1.3%), whereas it was unchanged in HLU‐mBMPR1A‐mFc (–0.3% ± 0.9%, p < 0.05 versus HLU‐VEH). Leg BMD increased significantly more in CON‐mBMPR1A‐mFc than CON‐VEH (10.2% ± 0.6% versus 4.4% ± 0.8%). In the femur, trabecular, and cortical bone microarchitecture was worse in the HLU‐VEH compared to CON‐VEH mice, whereas mBMPR1A‐mFc treatment for 3 weeks led to greater Tb.BV/TV, Tb.Th, and midshaft Ct.Th in both the HLU and CON groups compared to comparable VEH‐treated counterparts (p < 0.05). HLU‐mBMPR1A‐mFc mice also had 21% greater failure load (p < 0.05) compared to their VEH‐treated counterparts. Dynamic histomorphometry indicated that treatment with mBMPR1A‐mFc led to significantly greater mineralizing surface and mineral apposition rate, resulting in a 3.5‐fold and fivefold higher bone formation rate in the mBMPR1A‐mFc‐treated CON and HLU animals versus VEH groups, respectively. mBMPR1A‐mFc‐treated mice had a similar osteoblast surface but significantly lower osteoclast surface than VEH‐treated animals in both the CON and HLU groups. Altogether, these findings suggest that treatment with the soluble BMPR1A fusion protein may be useful for maintenance of skeletal integrity in the setting of disuse‐induced bone loss. © 2017 The Authors JBMR Plus published by Wiley Periodicals, Inc. on behalf of American Society for Bone and Mineral Research.


The effects of long-term exposure to a sea-floor depth ocean environment on the mechanical behavior of carbon-fiber / epoxy (CFE) continuous filament-wound composite tubes were investigated experimentally. Using a novel high pressure accelerated aging vessel and the Arrhenius relationship for water diffusion into a polymer matrix composite, the acceleration factor was determined to be approximately 21.5; that is one day of aging in lab at 70°C represents 21.5 days of real life service at 3°C. Specimens were aged for 0, 9, and 24 days which represent 0, 193.5, and 516 days of service. The specimens were sealed and half were subjected to external hydrostatic pressure until they imploded, and the other half were pressurized to 80% of the average implosion pressure previously determined and subjected to a strong impulse by means of a nearby explosive detonator. The behavior of the tube immediately before and during its collapse was recorded by high frequency pressure transducers and high speed digital stereo photography. In both the hydrostatic-initiated and explosive-initiated implosions, the composites did not significantly degrade nor change their properties with aging. These observations are in contrast to a previous study with nearly identical conditions except aged at atmospheric pressure. The results from this current study are supported by the conclusions of another study which studied CFE laminate aging under identical conditions. An additional set of experiments were performed using the same preparation methods and similarly sourced and dimensioned samples to investigate the impact of long-term deep-sea immersion on the composite's ability to hold internal pressure. The specimens were sealed and internally pressurized until leak or burst, and the phenomenon recorded by the same camera and transducer setup. It was found that the high pressure aging process did not significantly change the bursting pressure of the CFE tubes, but did significantly affect the fracture characteristics, which may have implications on non-bursting failure such as leaking.

With CMOS scaling emerging, new materials are being introduced to maintain performance enhancement in line with Moore's law. Currently, many candidate materials are under investigation to address the workfunction tuning issue in the future generation of transistors. According to the literature [1], some of the most likely candidates to be used as metal gate electrodes include Titanium based materials like TiN, Tantalum based materials like TaN, Mo and Ru. One common property of all these materials is their global outstanding corrosion resistance to chemicals used in wafer cleaning. These materials can be implemented in an integration scheme where thin metal layers are inserted between the high-k dielectric and the PolySilicon (PolySi) electrode during the gate stack formation. As a result, these new metal gates create a risk of galvanic enhanced corrosion at the gate electrode level during wet cleaning or etching. Formerly the galvanic corrosion was encountered only in the back-end-of-theline (BEOL) structures for instance between the copper interconnects and the metal barrier [2]. This problem was recently reported during the silicon oxide hardmask removal on the top of PolySi/metal transistors in dilute HF where PolySi was suffering enhanced corrosion upon coupling to metal gates [3]. The purpose of our study is to understand the mechanisms involved at the anode and the cathode sides to find solutions compatible with wafer cleaning particularities (short time and no surface modifications possible) to decrease or control this galvanic enhanced corrosion. Thin blanket layers of the metal gate materials under investigation (TiN, Mo, Ru and PolySilicon) were used for potentiodynamic polarization and galvanic currents measurements as function of the area ratio, dissolved oxygen, rotation rate, pH and silicon oxide etch rate. Measurements were done in 3 HF-based solutions characterized by the same thermal oxide etch rate around 12 nm/min, namely: 2% HF, 0.94%HF+2.45%NH4F and 0.61%HF+10%NH4F. In addition, 170 nm wide meander lines consisting of undoped or doped PolySi deposited on TiN or Mo on top of HfO2 were prepared with various anode/cathode area ratios. The patterned structures were cleaned in a 200 mm single wafer cleaning tool and the corrosion after the different treatments was evaluated using Scanning Electron Microscopy (SEM) inspection. Results are presented which describe the impact of galvanic corrosion on the nanostructures during the short cleaning time by comparing the different stacks. As expected the electrochemical results and immersion tests show corrosion variation depending on the gate stack and the integration scheme (basically anode/cathode ratio). The PolySi conductivity is an important factor determining the observed corrosion behavior and it can be modulated from almost an insulator to a metal like behavior by varying the doping; leading to distributed corrosion all over the PolySi (figure 1-left) or localized attack mainly at the PolySi/metal interface (figure 1right). The electrochemical results show that at the anode side the PolySi dissolution in coupling conditions is limited by the SiO2 etch rate of the solution (figure 2). By diluting the solution, the galvanic currents decrease. But it induces an increase in the cleaning time which is larger than the decrease in the corrosion. At the cathode side, dissolved oxygen was identified as contributing to the reduction mechanism on all the metal surfaces but in different regimes depending of the metals. Figure 3 shows the case of Mo where the reduction reaction mechanism is mixed kinetic-diffusion controlled. Galvanic currents measurements have shown that the removal of dissolved oxygen from the HF mixtures offers opportunities to minimize the galvanic corrosion for all the gate stacks without changing the properties of the cleaning solution. This approach was successfully implemented on a single wafer cleaning tool to control the galvanic corrosion too below acceptable levels.


This paper presents the design guidance of a wireless power modulator (WPM) for wireless power transfer (WPT) systems with multiple receivers. The WPM is implemented by an inductive-dominant relay resonator to alter the transimpedances among the receivers through the processes of enhancing, decoupling or weakening the magnetic flux in the receivers. The proposed WPM can manage the power flow of WPT systems without any control and communication devices, which improve the reliability and cost-efficiency. A 20 W WPT system with two LED loads is set up to demonstrate the effectiveness of the proposed WPM in regulating the power flow. The WPT system operates at 100 kHz.


In this study, the systematic analysis of nitrate assimilation and transport in soybean roots was further improved by analyzing the concentrations of nitrate assimilates, asparagine and glutamine, in soybean roots and the related enzyme activities. This provided a theoretical basis for the efficient utilization of nitrogen fertilizer in soybean farming. A dual-root soybean system with both sides being nodulated was used to provide nitrate withdrawal and resupply in three phases on one side, while the other side received nutrients without nitrogen under sand culture conditions. Measurements were taken of the root's nitrate reductase and glutamine synthetase activities, as well as the concentrations of asparagine. Measurements were also taken of the asparagine concentration in the basal root peeled skin (where the primary transport pathway is the phloem) and the woody parts (where the primary transport pathway is the xylem). Furthermore, the concentration of glutamine in the roots was also assessed. The findings indicated a positive correlation between the nitrate concentration in the roots and the activity of glutamine synthetase in the roots on both sides. The levels of asparagine in the roots, specifically those in the basal root peeled skin and woody part on both sides, rose when nitrate was added and declined when nitrate was removed. There was no significant change in glutamine concentration within the roots of soybeans. Hence, we deduced that the local provision of nitrate to the dual-root soybeans might enhance the absorption of nitrate into the roots on both sides. Additionally, the assimilated substances were predominantly carried as asparagine through the peeled skin and woody sections of the basal root, facilitating transportation in both directions within the soybean plants (from shoot to root and from root to shoot).


How pediatricians manage bronchiolitis and the derived total costs (direct and indirect) in the emergency department (ED) have not been fully characterized. The aim of the present study is to calculate those costs in a European country.


The dynamic structure factors, S(Q,ω), at a range of scattering vectors (Q) in the range 0.2<Q<3.0 A−1 are calculated in a molecular dynamics (MD) simulation of the viscous, network-forming liquid, ZnCl2. At intermediate Q (0.2<Q<0.5 A−1), Brillouin features, with shifts and widths proportional to Q and Q2, respectively, are observed. These features persist above the frequency of the "boson peak," in apparent discord with some suggestions for its origin. At high values of Q, close to the first peak of the static structure factor, a Q-dependent feature is seen in the inelastic part of S(Q,ω). This is analogous to a recent experimental observation on the similar, network-forming system B2O3 which was assigned to a "sound mode" contribution. An instantaneous normal mode (INM) analysis was applied to understand the relationship between these observations and the nature of the underlying modes of the liquid. The INM analysis accurately reproduces the observed (in MD) behavior of S(Q,ω) but does not support the...

About 15% of the world's population suffers from some form of disability. In developed countries, about 1.5% of children are diagnosed with autism. Autism is a developmental disorder distinguished mainly by impairments in social interaction and communication and by restricted and repetitive behavior. Since the cause of autism is still unknown, there have been many studies focused on screening for autism based on behavioral features. Thus, the main purpose of this paper is to present an architecture focused on data integration and analytics, allowing the distributed processing of input data. Furthermore, the proposed architecture allows the identification of relevant features as well as of hidden correlations among parameters. To this end, we propose a methodology able to integrate diverse data sources, even data that are collected separately. This methodology increases the data variety which can lead to the identification of more correlations between diverse parameters. We conclude the paper with a case study that used autism data in order to validate our proposed architecture, which showed very promising results.

P sychological practice in the inpatient medical setting is different in many ways from both outpatient clinical work and inpatient work in a psychiatric unit. Yet psychology trainees usually begin their first clinical placement in a hospital without any guidance or coursework on how to work in that setting. The same is true of established clinicians who have not specialized in health psychology. Although supervisors usually have a good grasp of the relevant issues, there is never enough time to sit with every trainee or to run a basic seminar on hospital work before the trainee begins. This book seeks to provide basic information on clinical and professional issues operative in the inpatient medical setting for individuals who already have skills in general clinical psychology but who have little experience in a hospital. It addresses clinical questions, such as the following:

Pericardial effusion is a common finding in clinical practice either as incidental finding or manifestation of a systemic or cardiac disease. The spectrum of pericardial effusions ranges from mild asymptomatic effusions to cardiac tamponade. Etiology is one of the main factors determining patient's prognosis. However, in most cases the pericardial effusion, even if large, remains of unknown origin.
 Pectus excavatum (PEX) is a common deformity of the chest wall in which the inferior part of the sternum and the cartilage are displaced posteriorly. PEX is present within the first year of life in most affected children, more frequently in boys than girls. The chest deformity in PEX may lead to compression of the right-sided cavities between the sternum and the vertebral column impacting right ventricular anatomy and rendering cardiac assessment by echocardiography very difficult.
 The diagnosis of pericardial effusion is generally confirmed by echocardiography but determining its etiology may be difficult. Although many cases are idiopathic, a careful review of the patient's medical history, physical examination, and laboratory tests can reveal the etiology in most patients. The most common causes of pericardial effusion are infections, malignant tumors, connective tissue diseases, pericardial injury syndrome, myocardial pericardial disease, uremia. In the last years, an association between idiopathic pericardial effusion and PEX has been hypnotized.
 We report the cases of 2 athletes, 15 and 18 years old, who came to our attention for post COVID19 infection evaluation as indicated by ministerial "Return to Play" protocol. Physical examination was negative for any signs/symptoms. Resting ECG showed normal sinus rhythm. Stress test was performed and resulted negative for signs and symptoms of reduced coronary reserve and arrhythmias. The echocardiographic evaluation showed moderate-severe pericardial effusion, 20 mm and 18 mm, in the absence of hemodynamic alteration. Blood tests were performed (including CRP, ESR, blood count, D-Dimer, IL-6, uricemia) and resulted normal. CardioRM confirmed the presence of severe effusion without signs of hemodynamic impairment/instability. Holter-ECG, performed during training session, resulted negative for arrhythmic events. Athletes were followed up with six-monthly echocardiographic, HolterECG and stress test evaluations, with unchanged entity of the pericardial effusion and any arrythmia or symptoms at serial controls.
 Chronic pericardial effusion without active pericardial inflammation may represent a diagnostic and therapeutic challenge, especially in the later years as COVID-19 disease and vaccination may be associated with pericardial injury. In the last years, PEX has been associated with the finding of pericardial effusion. Although of interest, caution should be used before labeling indiscriminately a pericardial effusion as due to PEX, especially when clinical insights suggesting alternative diagnosis are present, such as neoplasm or tuberculosis, or when any signs of hemodynamic instability are present. On the contrary, when an otherwise idiopathic pericardial effusion is occasionally identified in a patient with PEX, both the patient and the referring physician may be reassured of the benign association of these two clinical entities, in the proper clinical setting.


Tumor-targeting polymeric vesicles were prepared using a mixture of two amphiphilic block copolymers, namely, folate-poly(ethylene glycol)-poly(D,L-lactide) (folate-PEG-PDLLA) and NH2-PEG-PDLLA. The copolymers were synthesized through sequential anionic polymerization in a well-controlled manner. Hydrophilic superparamagnetic iron oxide nanoparticles (SPIONs) were encapsulated in the aqueous core of the polymeric vesicles. Similar to the hydrophilic SPIONs, the SPION-loaded polymeric vesicles exhibited the superparamagnetic property. Moreover, the SPION-loaded polymeric vesicles demonstrated a higher r2/r1 value than a commercially available T2 agent, Resovist®, which can be attributed to the high SPION loading level and the SPION clustering effect in the aqueous core of the vesicles. Thus, tumor-targeting, SPION-loaded polymer vesicles can serve as highly efficient T2 contrast probes for cancer diagnosis and treatment.


Basic family decisions like desire to limit child-bearing, sex of the new-born or child care are not always an individual affair but involve interaction between choices of men and women in the family. This study examines how background characteristics as well as decisions of men and women determine the family outcomes such as, women's fertility, family-size, sex preference of the new-born and children orphan-hood. Our analysis is performed using cross-sectional data pertaining to 29 states of India. The results indicate that while men's preferences for male children remain as a significant barrier to fertility reductions, women's literacy level can contribute to the men's decisions of limiting family-size. The men's literacy along with women's lack of media exposure weakens women's desire for controlling familysize and also enhances their preference for the male child. Finally, while alcohol use by men and literacy level or cash earning of women plays a role for the separation of children from their parents, the lack of wealth possession and men's literacy level seems to have prevented the abandonment of children across Indian states.


We have developed novel 1.1-μm-range InGaAs VCSELs with buried type-II tunnel junctions for high-speed optical interconnections. A relaxation oscillation frequency of 27 GHz was achieved. Error-free 30-Gbps operations were demonstrated using directly modulated multi-mode VCSELs.


The application note explains how the Raman Spectroscopy can be helpful in the analysis of cathodes and anodes in Li-ion batteries.


This study aimed to find out whether the integration of the English Pronunciation app in pronunciation class at Mandalika University of Education (UNDIKMA) can increase students' participation and self-learning. This study made use of quasi-qualitative design. Forty-eight first-year English department students from two groups of learning involved in this research, aged between 19 to 21. Each group, group A and group B, comprised of 24 students. Both groups received instruction using the English pronunciation app. Data was collected using class observation and interviews. In conducting observation, the observer chose to take the role of participant-observer in that the researcher immersed with the students during the observation activities. One volunteer assistant was employed to work with the researcher. It was intended to increase the accuracy of the data collected. In regard to the interview process, the researcher used individual and group interviews where one interviewer/researcher interviews a group of students. The result of the study indicates that the integration of the English Pronunciation app in teaching pronunciation increased the students' participation (engagement, attitude, and conduct). In addition, the app brought a positive effect to the establishment of independent learning to a significant number of students.


FIELD: technological processes. SUBSTANCE: fluidized layer temperature (24) is greater than 300°C and less than 900°C. The introduction of the fine material (4) is carried out by the burner (2) directly into the fluidized layer (24) and/or into the free space (25) above the fluidized layer (24). At the same time, the surface of the fine particles (4) is fused and agglomerates are formed which are kept in suspension by the upwardly flowing reducing gas. The particles contained in the agglomerates containing iron oxide are reduced and removed from the reducing unit (1). EFFECT: invention allows the use of a finely dispersed material comprising a large number of iron-containing particles, without being pretreated directly in the cast iron production process and/or direct reduction process without adversely affecting the cast iron production process. 15 cl, 3 dwg


This paper analyzes the financing problem, which confines the development of the small and medium-sized enterprises, the current situation and its reasons, and proposes corresponding strategies, in order to give play to the potential abilities of the small and medium-sized enterprises, which will play a greater role in economic development and social stabilization.


To determine the target resistance of concrete materials,the constitutive description of concrete materials idealizes the pressure-volumetric strain as tri-linear equations of state,and the shear strength-pressure as Mohr-Coulomb with tension cutoff and shear saturation.The response of semi-infinite concrete target under high velocity impact is divided into four zones of elastic,cracked,compacted and condensed.The quasi-static spherical expansion theory is developed,target resistance in A-T model is determined,and the penetration depth of semi-infinite concrete targets penetrated by high velocity long rod projectiles is analyzed.The analytic result of penetration depth is in good agreement with experiment data.


This paper underlines selection processes in the Belgian educational school system. It analyses the schools' reactions to the recent modification of the enrolment policy that diminishes the freedom that schools have historically benefitted from to regulate their population. The paper shows that the management variations between schools have to be understood with regard to the local interdependencies between them. These local interdependencies constitute hierarchies that form a frame for individual actions in school which contribute to reproduce the hierarchical structure. Doing so, it insists on the necessity to understand the quasi-market and the competition between schools by taking in account the local social and demographic context. School managing practices are not only due to a mechanical cause-effect link with their position in the educational hierarchies. This paper shows that, when studying the actors' perception in detail, the hierarchies constitute a frame for their actions at a more local level. In this sense, the weight of hierarchies and interdependencies is not automatically built on the spaces defined by flow of pupils between schools. Theses spaces are not a fixed frame for educational actions even within schools sharing a similar position in the hierarchies.


Abstract Phosphorus (P) deficiency in soil is a common spring wheat production-limiting factor in Montana. In a pot experiment, three groups of spring wheat genotypes based on source (association mapping, 2016 off-station, and nested association mapping) were grown in 5 (P5) and 30 (P30) mg P kg−1 potting mix conditions and screened for P deficiency tolerance. Plant height, tiller and head number, grain yields per pot measured were significantly different between P5 and P30 conditions (p < .05). Spring wheat genotypes: Unity, Peace, Vida, Reeder, CLTR 15134, ONeal and Fortuna yielded more grains, and equally took up more P in P5 conditions, revealing some degree of P deficiency tolerance. The genetic variability identified in this study for grain yields and P uptake could be used in wheat improvement programs for selecting genotypes with low P tolerance in P deficient soils as well as in organic spring wheat production.

THis butterfly (Iphiclides Ajax) occurs east of the great plains, in the Carolinian and the southern half of the Alleghanian fauna; it extends north almost to the annual isotherm of 50, even passing that line in the region of the great lakes, so as to include southern Michigan and the whole of Ohio, but, apparently, not following the upward curve of the isotherin beyond the Mississippi. In the south it reaches the gulf coast, but how far it extends down the Florida peninsula is undetermined; its, western extension is unknown; it has been reported neither from Texas nor Arkansas, although it is common in Missouri (Riley). Prof. Parker states that it occurs on the Mississippi at least as far noi'th as Rock Island, Ill., and that he hats taken a few specimens at Keokuk and Davenport, Iowa, although none at Grinnell. It occurs in southern Michigan (Mus. Mich. Univ., Andrews) and in many localities in Ohio, such as Cleveland-" not uncommon"(Kirtland); "'common where papaw bushes are" (Kirkpatrick) ; Columbus, "still more abundant" than at Cleveland (Kirtland); Rockport, Poland and Hudson (Kirtland) and Eastern Ohio.(Foster); a single specimen has been reported from Komoka, Ontario, Canada (Saunders).

Silver and its compounds have been used for thousands of years as antibacterial and medicinal agents. Silver nanoparticles (AgNPs) subsequently received much attention due to their unusual physical, chemical, and biological properties, which are mainly caused by AgNP size, structure, composition, luster, and structure compared to their bulk species. When free radicals interact with bacteria, they can cause damage to the cell membrane, enabling it to penetrate and eventually lead to cell death. Compared to other salts, silver nanoparticles have excellent antibacterial activity due to their large surface area, allowing for high interaction with bacteria. There are many techniques for producing silver nanoparticles, including physical, chemical, and biological processes.Physical and chemical processes for making silver nanoparticles are expensive and complicated, whereas biological approaches are easier and safer to implement. In the biological and environmental areas, metal nanoparticles with controlled particle size and surface chemistry have a broad spectrum of applications. Nanomaterials must becharacterized in addition to the manufacturing procedures to explore differences in activity based on morphological distinctions. AgNPs are widely used as antibacterial agents in the field of health, food storage, textiles, and various environmental applications.So, in this systematic review, we examined silver nanoparticle preparation methods, characterization, applications, and fundamental concepts of silver nanoparticles (AgNPs).


Metabolic syndrome, a major risk factor for cardiovascular disease, is increasingly recognized in adolescent patients. Exposure to tobacco smoke appears to be independently associated with insulin resistance. In this study, researchers who had previously demonstrated that 6% of adolescents at risk for overweight and 29% of overweight adolescents met criteria for the metabolic syndrome now examine …


This volume is part of a ten volume set of papers derived from the Third International In Situ and On-Site Bioreclamation Symposium which was held in San Diego, California, in April 1995. The purpose of the conference was to provide a multidisciplinary forum for exchange of state-of-the-art information on bioremediation. The papers in this volume focus on petroleum hydrocarbon bioremediation, with an emphasis on pilot-scale and field-scale applications. Individual papers have been processed separately for inclusion in the appropriate data bases.


The invention relates to a wet spraying machine of concrete drier, which comprises a spraying machine, a water pressure booster and a powdered accelerator adder. The wet spraying machine of concrete drier integrates the advantages of a dry spraying machine and a wet spraying machine, achieves the upgrade of the concrete spraying technology, improves the sealing performance and reduces the dust generation and the pipe plugging times. The water pressure booster is designed to enable the water pressure to be higher than the wind pressure; water is added into a concrete conveying rubber pipe, so that water and concrete are effectively mixed to achieve the operating process of wet spraying of dry material. The invention has simple operation and can achieve the effects of low rebound and less power. The powdered accelerator adder enables the powdered accelerator to be quantitatively, uniformly and continuously added in the wet spraying process.


In the design of various electromagnetic equipments, an important role is that of iron losses that must be calculated as precisely as possible. The analysis of the author has shown that the computation of the iron losses using constant coefficients does not ensure, generally, I high accuracy. An approach to the separation of measured losses in the case of an alternating magnetization field is presented. In the case of a rotational magnetization field, the computation of iron losses cannot reach a high precision with the methods known at present since, in this case, the hysteresis loop that usually is obtained for the case of alternating magnetization is no more valid. For this reason it is necessary the experimental determination of the losses in the two cases: alternating magnetization and rotational magnetization. This task has been achieved using a model. In the paper the obtained results are given.


Twelve intervarietal crosses and ten interspecific crosses of gladiolus were tested separately in RCBD, each with 4 replications in the field of Agriculture Research Station, Dailekh from 2010 to 2011.The objective of the study was to find the potentiality of seed set in different crosses within and between the species. Under intervarietal crosses, high pooled capsule set per spike resulted in 'Ginger Red x G-4' (95.0 %), 'G-4 x American Beauty' (92.5%), 'Intrepid x G-4'(92.5%), 'G-4 x Intrepid' (91.7%), 'American Beauty x G-4'(88.5%) and 'Intrepid x American Beauty'(83.15%),but 'Ginger Red x American Beauty' and 'Ginger Red x Intrepid' produced the lowest pooled capsule set per spike with 50.1% and 53.8% respectively. 'Intrepid x G-4' produced the highest pooled number of seed sets with 66.0 per capsule followed by 'G-4 x American Beauty' with 44.0 and 'G-4 x Intrepid' with 44.0 while both 'Ginger Red x American Beauty' and 'Ginger Red x Intrepid' produced the lowest pooled number of seeds with 2.0 per capsule. Under the interspecific crosses, Pooled number of seed set per capsule was inconsequentially high in ' Psittacinus hybrid x G-4' with 56.0, 'Intrepid x Psittacinus hybrid' with 54.0 and 'White Prosperity x Psittacinus hybrid' with 52.0. The seed set due to the effects of present crosses of gladiolus are more satisfactorily successful than those in the previous studies. Incorporation of genotype 'G-4' and 'Intrepid' both as female and male parents have contributed to high number of seeds per capsule presumably due to inherent varietal trait coupled with favorable environment for triggering seed set.

Bexhill Museum is probably the museum most in need of help in the region. The geological collections have been wrapped in newspaper, nailed-up in crates, and stored in a cellar prone to flooding since the 1930s. A curator is soon to be appointed and the collections are slowly being recovered. I have not been able to examine much of the material in detail but in some of the boxes of Folkestone Gault fossils many of the specimens had been transformed, through the crystallisation of salts and pyrite decay, into a muddy slurry. The crates contain individual named collections including Lady Anne Brassey, E.A. Butler, J.A. Pepys, F.J. Richards, Lt Col R.B. Unwin, Rev J.C. Thompson, Henry...


According to the principle of carrier diffusion, aluminum nitride (AlN) coating, and RIE deep etching technology are implemented, 1064 nm broad area distribution electrode lasers have been obtained exhibiting near single lobe near and far field. We report electrode pattern lasers emitting at 1064 nm with the minimal full width at half maximum (FWHM) horizontal angle of 2.7° while the maximum continuous-wave output power up to 3.65 W and slope efficiencies as high as 0.85 W/A.


In a recent Letter, Baer et al. present a stochastic method for Kohn-Sham density functional theory calculations. Their convergence criterion is the self-averaging total energy per electron, which requires a number of statistical samples that decreases with system size and enables a sublinear-scaling computational cost. However, the electron density, atomic forces, orbital energies, and many other physical quantities do not self-average, and this procedure causes their statistical errors to grow with system size. Convergence of non-self-averaging quantities requires that the number of samples be maintained with system size and is incompatible with a sublinear-scaling cost.


The invention provides a test device for dynamically measuring fretting pair frictional coefficient during the fretting fatigue process. A frictional coefficient measurement component realizes the fretting working condition and dynamically measures the frictional coefficient of a fretting pair formed by the cooperation of a fretting section and a fretting pad of a test piece during the fretting fatigue process; a normal force loading component realizes load applying in the horizontal direction; an upper-end fixing component realizes the fixing of the test piece and a clamp body; the horizontal direction loading in the fretting fatigue test is realized by adopting a hydraulic system; the loading system adopts a closed force system frame structure; the piston rods of hydraulic cylinders pushes the fretting pad to clamp a sliding block to move in a sliding groove in the clamp body; the frictional coefficient measurement component is fixed on the upper-end fixing component through a pin bolt; in the vertical direction, except the own gravity and the gravity of the hydraulic cylinder, the frictional coefficient measurement component only receives the frictional force produced due to fretting action between the test piece and the fretting pad; by adhering a strain piece to the working section of the clamp body and calibrating, dynamic monitoring of the frictional coefficient of the fretting pair during the fretting fatigue test process is realized.


We have demonstrated what is to our knowledge the first Nd:YVO4 laser longitudinally pumped by a surface-emitting laser diode. An optical/optical efficiency of 32% was obtained with a nearly diffraction-limited beam.


Since the introduction of the SA Schools Act in 1996 and institution of school governing bodies (SGBs), the Education Department began to experience serious problems regarding school governance. The incidents that happened in schools brought into question the legal role and authority of SGBs in the administrative actions they perform. This study aimed specifically at investigating the problems that arise in relation the appointment of teachers. Since SGBs play an important facilitating role in the process of staff appointments, their way of handling this duty was at the heart of the study. The research made use of literature studies, policy documents from the education department, viz. the SA Schools Act, Educators Employment Act, Education Labour Relations Council documents, and questionnaires and interviews with members of school governing bodies at a selection of local schools in the Western Cape Province. The findings led to the conclusion that most SGBs in the disadvantaged communities find it difficult to appoint new educators. Clearly SGBs are regarded as legitimate structures that should govern learning institutions and it is evident that one of their duties is to employ new educators, in line with the legal procedures stipulated in the various provincial education departments' policies. Perhaps the most important finding is that parents in the disadvantaged communities are illiterate. This is a significant problem because most of their duties require them to read documents from the education department so that they may know exactly how to perform their functions and responsibilities. Some of the problems encountered, however, are also caused by the ignorance and reluctance of parents to offer their services without being remunerated. These conclusions resulted in the formulation of specific recommendations for improving the role and implementation of SGBs. The recommendations are made for improving the role of SGBs as a whole as well as for specific capacity building relating to the needs of each stakeholder group. The overall emphasis of the study is thus on the recommendation for more effective training of SGBs. III Stellenbosch University http://scholar.sun.ac.za


High-frequency financial data are not only discretely sampled in time but the time separating successive observations is often random. We analyze the consequences of this dual feature of the data when estimating a continuous-time model. In particular, we measure the additional effects of the randomness of the sampling intervals over and beyond those due to the discreteness of the data. We also examine the effect of simply ignoring the sampling randomness. We find that in many situations the randomness of the sampling has a larger impact than the discreteness of the data.

The internship was done for the combined master SET and ChE-PT and covered a period of 5 months. The assignment was provided by the University of the Western Cape (UWC) in Cape Town, South Africa. UWC cooperates in research projects with Eskom, South Africa's electricity company.
Eskom is developing Underground Coal Gasification (UCG) on a commercial scale. UCG is a process to gasify coal underground, this yields a product gas rich in H2, CO2, CO and CH4. This gas can be used in a gas turbine to produce electricity or can be used as a synthesis gas to produced chemicals. UCG has the potential to become a so called 'clean coal technology' because the emissions of SOx and NOx are reduced and CO2 can be captured before combustion. UCG has large economical potential because unminable coal seams (too thin or too deep) can be recovered by it. This is relevant for South Africa, because the country relies heavily on its large coal reserves for both electricity and transportation fuels.
The assignment involved the design of a hydrogen plant to produce ultra pure hydrogen from the UCG product gas. A small membrane based process was designed that can be placed at the UCG demonstration plant. Various designs were made and both the capital investment and the production costs of them were compared.
A polymer membrane module was tested at the current UCG pilot plant on the UCG product gas. For this an experimental setup was build and 3 weeks of testing was done. The acquired data was used in the design of the hydrogen plant.
The experimental work was presented at the International Underground Coal Gasification conference held on 13-14 July 2011 in Johannesburg (South Africa). The extended abstract which was hand in for the conference can be found on blackboard.

Here we show preliminary calculations of the cooling and con traction of a 2MJ planet. These calculations, which are being extended to 1–10 MJ, differ from other published "cooling tracks" in that they i nclude a core accretion-gas capture formation scenario, the leading theory for the form ation of gas giant planets. We find that the initial post-accr etionary intrinsic luminosity of the planet is∼3 times less than previously published models which use arbi tr y initial conditions. These differences last a few tens of millions of years. Young giant planets are intrinsically fainter than has been previ ously appreciated. We also discuss how uncertainties in atmosphe ric chemistry and the duration of the formation time of giant planets lead to challenges in deriving planetary physical p roperties from comparison with tabulated model values.


Inorganic zeolites are used in many practical applications due to their unusual microporous structures.A 3D inorganic zeolites[CoNa_6(SO_4)4(H_2O)_2]_n was reported in this paper.The compound was characterized by X-ray crystallography and crystallizes in monoclinic with space group Pī.The crystallographic data of the complex are: a = 0.60483(12)nm,b = 0.68280(14)nm,c = 1.0094(2)nm;α = 109.13(3)°,β = 92.57(3)°,γ = 105.53(3)°.Additionally,the further quantum chemistry analysis would benefit for researching the stability of this complex and could help us to further explore its reactivity.


either," quipped Rainer Werner Fassbinder, star director and enfant terrible of the New German Cinema movement (1992, 79). For Fassbinder, human togetherness was a problem, not an answer, an artistically generative paradox stalled indeWnitely at the crossroads of misanthropy and jouissance. Caught in the crossWre of political and social codes of belonging, erotic dramas of compulsion provided continual grist for the mill of Fassbinder's proliWc yet brief directorial career. To understand what constructed, for Fassbinder, this particular link between compulsion and belonging, conXict and togetherness, eros and polis, Fassbinder's Wlms must be considered within their historical framework, a period in German history when the question of national identity was being reexamined across every cultural and aesthetic milieu.1 Fassbinder's 1974 social melodrama, Angst Essen Seele Auf (Ali, Fear Eats the Soul) stands out in particular among his many Wlms of the period as the most seemingly hopeful and yet most bitterly critical treatment of this socially speciWc and historically located problem of human togetherness. Dwelling neither on Fascist recidivism, nor on vestigial cultural ideologies, nor on the traumas of war, this Wlm's critique is aimed instead at West Germany's melioristic social project; speciWcally, the Wlm pits itself against certain neoliberal Wctions of rehabilitation that would conXate economic gains with social "progress." The Wlm reveals that this deliberate cultural project entails less a renewal of West German national identity than a denial of the true economic and legal conditions underwriting the nation-state's present prosperity. Angst Essen Seele Auf has been predominantly discussed under a Wlm studies historical rubric that situates its genre—melodrama—and Jus sanguinis, Jus soli


Successive protonation of [Fe4S4(SPh)4]2– progressively labilises the cluster towards substitution of the thiolate ligands, whereas single protonation of [Fe4S4Cl4]2– catalyses, but diprotonation inhibits, substitution of the chloro-ligands.

The effect of simulated tire-building steps on morphological characteristics of polyethylene terephthalate (PET) cords and their final dimensional stability is reported. Twisted single-ply cords were sequentially processed for mimicking dip coating (without real latex treatment), thermal curing (without embedding them in rubber matrix), and creep deformation. The degree of crystallinity and crystalline orientation factor (f c) of the samples remained essentially unchanged in the course of the simulated manufacturing steps. As measured by birefringence, overall orientation of the cords increased in the coating step but decreased during simulated curing. Overall orientation again increased after creep testing. As measured by wide-angle X-ray diffraction, the cords having higher oriented amorphous (mesophase) content displayed the least variation in overall orientation during processing steps and the best dimensional stability.

Non-functional requirements determine the characteristics of a software product or service as a whole. The research described in this paper presents an empirical framework involving respondents of both the project and the business organisation, in order to select and prioritise a list of non-functional requirements for implementation during software project development. The assessment process takes into consideration the extent of relative value addition while making trade-off in selection of non-functional requirements for inclusion in the project's requirement set. The final results are expected to be beneficial to both the business and the project organisation by identifying and implementing the desired non-functional requirements that contributes to business value in a cost effective manner.


In a consumer culture essentially visual, cinematic representations makeup a social imaginary and integrate a symbolic universe that affects culturalpractices. From that perspective, this article develops a research study andreflection on the representation of the aging female in contemporary Braziliancinema, highlighting matrices of resistance in audiovisual narrativesthat respond to hegemonic practices. It is expected, nevertheless to provideplural, creative and subversive views about the subject, within women'sliberation and possibilities of dialogue with the masculinity.


Summary Zonal centrifuge separation of homogenates of normal and neoplastic brain tissues is described. A unique zone is identified as myelin-rich but also containing synaptosomes. This zone appears both in human adult white matter and in human brain tumors that are of the infiltrative type but is absent from human fetal brain and from certain noninfiltrative, encapsulated brain tumors. The same zone is also characteristic of normal rat brain and can be recovered and rezoned without change in its zoning position. After three successive recoveries, the cholesterol-phospholipid molar ratio of the material in this zone rises, for example, from 1.06 to 1.33 to 1.55. With cesium chloride banding the myelin component remains at a density of 1.09, but the synaptosome component bands at a higher density of 1.15.


The temporary Venezuelan specification for buildings resistant to earthquakes prescribes a limited lateral deformability but a basically flexible behaviour in order to reduce dynamic response. Such a structure is obtained if columns are built very near each other and rigidly linked together within the perimeter of the structure. Angle columns are eliminated so as to increase the interaction of the four walls of the structure. A mathematical model is derived which assumes plane frames and which is based on the comparison of deformations taken into account in the following 2 hypotheses: with or without transfer of shear forces at the angles of the structure (tubular effect) and consideration or not for each hypothesis of axial deformations of the columns.


Acetoin, a four-carbon hydroxyl-keto compound, is used in the food, pharmaceutical, and chemical industries. The cascade enzymatic production is considered a promising and efficient method to produce acetoin. However, the stability and compatibility of the enzymes under the same catalytic conditions are challenges that need to be resolved. In this work, alcohol dehydrogenase, acetaldehyde lyase, and NADH oxidase were selected to work at the same conditions to efficiently convert ethanol into acetoin. These three enzymes were immobilized on epoxy-modified magnetic nanomaterials to obtain highly stable biocatalysts. The stability and the immobilization conditions, including temperature, pH, enzyme–carrier ratio, and immobilization time, were optimized to obtain the immobilized enzymes with a high catalytic activity. The cascade reactions catalyzed by the immobilized enzymes yielded a high conversion of 90%, suggesting that the use of immobilized enzymes is a promising way to produce acetoin.


6 Abstract The high prospects of exploiting the oxygen reduction reaction (ORR) for 7 lucrative technologies, for example, in the fuel cells industry, chlor-alkali electroly8 sis, and metal-air batteries, to name but a few, have prompted enormous research 9 interest in the search for cost-effective and abundant catalysts for the electrocatalytic 10 reduction of oxygen. This chapter describes and discusses the electrocatalysis of 11 oxygen reduction by metallomacrocyclic complexes and the prospect of their poten12 tial to be used in fuel cells. Since the main interest of most researchers in this field is 13 to design catalysts which can achieve facile reduction of O2 at a high thermodynamic 14 efficiency, this chapter aims to bring to light the research frontiers uncovering 15 important milestones towards the synthesis and design of promising metalloma16 crocyclic catalysts which can accomplish the four-electron reduction of O2 at low 17 overpotential and to draw attention to the fundamental requirements for synthesis of 18 improved catalysts. Particular attention has been paid to discussion of the common 19 properties which cut across these complexes and how they may be aptly manipulated 20 for tailored catalyst synthesis. Therefore, besides discussion of the progress attained 21 with regard to synthesis and design of catalysts with high selectivity towards the four22 electron reduction of O2, a major part of this chapter highlights quantitative 23 structure–activity relationships (QSAR) which govern the activity and stability of 24 these complexes, which when well understood, refined, and carefully implemented


Comparative molecular similarity indices analysis (CoMSIA) were performed on N-dichloroacetyl oxazolidine derivatives as herbicide safeners. The best CoMSIA models that were generated using atom based alignmen, Rcv2=0.632, n=4, R2=0.927, F=31.796 and s=0.097. The contributions of steric field, electrostatics field, hydrophobicities field and hydrogenbond acceptor were 0.127, 0.260, 0.285 and 0.328, respectively. The CoMSIA model was satisfactory and would be useful for the future design of new N-dichloroacetyl oxazolidine herbicide safener.


Background: Chronic subdural hematomas (CSDH) tend to occur in elderly patients with a history of mild head injury few weeks prior to the onset of symptoms. Arachnoid cysts (AC) are relatively common congenital intracranial mass lesions that arise during the development of the meninges. However, these two distinct clinical entities sporadically occur together in relatively young patients. Objective: In light of a literature review, a trial to explain the association between arachnoid cyst and subdural hematoma is proposed. Patients & Methods: This is a report of four cases presented with chronic subdural hematoma over the frontoparietal region, with an incidental finding of an arachnoid cyst over the Sylvian fissure. Results: Three patients were males and one female. Age ranged from ten years to forty one years. All patients had history of minor head trauma. Their symptoms were due to intracranial hypertension, like those with isolated CSDH. All patients' symptoms regressed after evacuation of CSDH. Conclusion: Arachnoid cyst is a possible risk factor for subdural hematoma in young adults. A burr hole procedure with drainage of hematoma is an adequate treatment. © 2014 Egyptian Journal of Neurosurgery. Published by MEDC. All rights reserved


The local structure of Mn impurities in a ferromagnetic (Ga, Mn)N semiconductor was investigated using extended X-ray absorption fine structure (EXAFS). The ferromagnetic signal increased and maintained up to room temperature as N ions were implanted into Mn-implanted GaN. The X-ray results showed that Mn ions occupied Ga sites to form (Ga, Mn)N semiconductor. The Mn concentration occupying Ga sites increased from 2.5 to 3.8% and the formation of Mn-N compounds such as Mn 6 N 2 . 5 8 and Mn 3 N 2 was prohibited by implanting N atoms. As a result, the N-vacancies reduced and net hole concentration increased, resulting in the enhancement of ferromagnetic property.


The digital divide refers to the differences between people who use technology on a regular basis (technology-enabled) and those who do not use technology regularly (technology-disabled). Van Dijk describes three mechanisms that affect the use of technological resources. These are social exclusion, exploitation, and control. In addition to these three mechanisms, the technology itself may exclude potential users through the application design process. The design method used most frequently relies on convenience sampling of current users. The choices that these technology familiar users make in testing lead development teams to interaction design decisions that may exclude novice users. Several theories of technology adoption are reviewed as well as past and potential ways to address the digital divide.


We present rush as a recommendation-based interaction and visualization technique for repeated item selection from large data sets on mobile touch screen devices. Proposals and choices are intertwined in a continuous finger gesture navigating a two-dimensional canvas of recommended items. This provides users with more flexibility for the resulting selections. Our design is based on a formative user study regarding orientation and occlusion aspects. Subsequently, we implemented a version of rush for music playlist creation. In an experimental evaluation we compared different types of recommendations based on similarity, namely the top 5 most similar items, five random selections from the list of similar items and a hybrid version of the two. Participants had to create playlists using each condition. Our results show that top 5 was too restricting, while random and hybrid suggestions had comparable results.

Nutmeg ( Myristica fragrans Houtt.) is an evergreen tree and popular spice. In the present study, Random Amplified Polymorphic DNA (RAPD) analysis was performed to assess the genetic diversity among the 19 superior accessions of nutmeg collected from different geographic locations and maintained in the germplasm collections of Regional Agricultural Research Station, Kumarakom, Kerala. This included one released variety IISR Viswasree. Out of 28 RAPD primers tested, 20 were amplified. Out of the 109 loci amplified, 82 were polymorphic with an average polymorphism rate of 72.74 per cent. The number of bands for each primer ranged from 2 to 8. The markers which produced maximum number of polymorphic bands were BB-18 and PO-5. PIC value of the markers ranging from 0.09 (OPA 11) to 0.48 (W-15) with an average of 0.31. The marker index (MI) varied between 0.09 and 2.08 with an average of 1.25. Jaccard's similarity co-efficient of the genotypes ranged between 0.34-0.93. Dendrogram constructed based on UPGMA analysis grouped the 19 selected genotypes into two major clusters. The knowledge on genetic diversity of nutmeg can be used for further breeding programmes for getting higher nut and mace yield.


After examining ternary Al-based quasi-crystalline phase diagrams, we pointed out that the presence of e/a -constant and e/a -variant lines is a common phenomenon. Ternary quasi-crystal compositions are located at the crossing point of these lines in ternary phase diagrams. Such an empirical rule can be used to predict the ternary quasi-crystal compositions from binary ones. We applied this rule to the Al–Fe–Ni system and clarified the decagonal phase composition zone. There are two decagonal phases, D-Al_72.5Fe_14.5Ni_13 and D′-Al_705Fe_12Ni_17.5, that correspond respectively to Al–Fe-based and Al–Ni-based decagonal phases in the same ternary system.

Transparent ceramics are emerging as future materials for lasers, scintillation, and illumination. In this paper, an interesting and surprising phenomenon in YAG transparent ceramics is reported. UV light leads to significant changes in the microstructure of open volume defects and nano clusters as well as in the optical properties. Light-induced lattice relaxation is suggested as the mechanism behind this intriguing behavior. The complex F-type color center with broad absorption bands is caused by the aliovalent sintering additives (Ca2+/Mg2+) and Fe ion impurities. Two individual peaks in the thermoluminescence spectra illustrate both shallow and deep level traps. From positron annihilation lifetime data, vacancy clusters and nanovoids are detected and characterized, although these free-volume defects could not be observed by high-resolution transmission electron microscopy. The solarization induced by UV irradiation is associated with a change in the structure and size of defect clusters due to lattice relaxation. Therefore, this work shows how UV irradiation leads not only to a change in the charge state of defects, but also to a permanent change in defect structure and size. It significantly affects the optical properties of YAG ceramics and their performance in lasers and other optical applications. These results are crucial for advancing transparent ceramics technology.


Using the triaxial satellite simulators without creating balance will lead to the existence of gravity disturbance torque during the experimental process. In order to solve these problems, the triaxial satellite simulators must be balanced. The balancing method is based on a double motor automatic balancing method. This approach enriches the triaxial satellite simulator's automatic balancing method, and greatly improves the precision of automatic balancing. The effective implementation of the two-motor balancing method offers a good guarantee for subsequent experiments.
