CoCr2O4 belongs to the cubic spinel family where Co2+ occupies the tetrahedral A sites and Cr3+ populates the octahedral B sites [1]. Single crystals of CoCr2O4 undergo a paramagnetic to ferrimagnetic transition at TC = 93 K, and subsequent lowering of the temperature leads to a conical spin state at 26 K (TS) [1]. The appearance of ferroelectricity in CoCr2O4 has been ascribed to this spin modulation [1]. At 15 K, the compound shows the lock-in transition[1]. In polycrystalline CoCr2O4 spinel compounds, both ferrimagnetic and spiral magnetic orderings were observed at 94 K and 27 K, respectively, with missing lock-in transition [2]. The results of multiferroicity in CoCr2O4 were confirmed [3], where the conical-spiral ferroelectricity has been referred to as the interrelation of ferroelectric polarization, magnetization, and spiral wave vector [3]. The observed findings suggest that the nearest neighbor and isotropic antiferromagnetic A-B and B-B exchange interactions JAB and JBB compels the system to attain a "ferrimagnetic spiral", having spins located on the conical surfaces [3]. The occurrence of spiral ordering at 25 K has also been observed in CoCr2O4 nanoparticles (about 40 nm) without any lock-in transition [4]. The disappearance of TS also occurred in undoped and Ni substituted CoCr2O4 thin films [5]. As a strong motivation of the importance of the spiral ordering and the exchange interaction, the present work aims at the substitution of rare-earth Ce3+ ion at Cr3+ site. A Co(Cr0.95Ce0.05)2O4 compound was synthesized by the sol-gel technique. Xray diffraction (XRD) studies of the sample calcined at 600 C, revealed pure phase. The crystallite size estimated from the XRD was approximately 9 nm. The average particle size calculated from the transmission electron microscopy (TEM), DT EM = 11 ± 2 nm. Electron diffraction patterns confirm the crystalline nature of the nanoparticles. Magnetization as a function applied field shows an increase in coercivity below TC with subsequent lowering in temperature. Magnetization measured as a function of temperature indicated the ferrimagnetic TC = 86 ± 1 K which is lower and TL = 15 ± 2 K in agreement with the reported values for CoCr2O4. Interestingly the spiral ordering was smeared by the substitution of Ce at the Cr site. The present work envisages the impact of rare-earth ion substitution at the B site that can alter the exchange interaction in such a way that causes suppression of the spin modulation.

Accurate, reliable timestamping which is also convenient and inexpensive is needed in many important areas including real-time network applications and network measurement. Recently the TSC register, which counts CPU cycles in popular PC architectures, was proposed as the basis of a new software clock which in terms of rate performance performs as well as more expensive GPS alternatives. Smooth and precise clock rate is essential to measure time differences accurately. We show how to define a TSC based clock which is also accurate with respect to absolute time. The clock is calibrated by processing, in a novel way, timestamps contained in the usual flow of Network Time Protocol (NTP) packets between a NTP server and the existing software clock, and TSC timestamps made independently on the host side. Using real measurements over 4 months, validated with a GPS synchronized hardware timing solution, the algorithm measured absolute time with a median error of only 30 microseconds when using a nearby stratum-1 NTP server. Results for two other servers are given. We also provide new algorithms for the robust determination of clock rate. We exploit the reliability of the available hardware to design synchronization algorithms which are inherently robust to many factors including packet loss, server outages, route changes, temperature environment, and network congestion.


Estimating glomerular filtration rate (GFR) in elderly patients is a problem, since they are poorly represented in studies developing GFR equations. Serum cystatin C is a better indicator of GFR than serum creatinine in elderly patients. Therefore the aim of our study was to compare frequently used serum cystatin C based GFR equations with a gold standard (51CrEDTA clearance) in elderly chronic kidney disease (CKD) patients. 106 adult Caucasian patients, older than 65 years (58 women, 48 men; mean age 72.5 years), were included. In each patient 51CrEDTA clearance, serum creatinine (IDMS traceable method) and serum cystatin C (immunonephelometric method) were determined. GFR was estimated using the Simple cystatin C, CKD‐EPI cystatin C, CKD‐EPI creatinine‐cystatin C and BIS2 equation. Mean serum creatinine of our patients was 141.4 ± 41.5 μmol/L, mean serum cystatin C 1.79 ± 0.6 mg/L, mean 51CrEDTA clearance was 52.2 ± 15.9 mL/min per 1.73 m2. Statistically significant correlations between 51CrEDTA clearance and all formulas were found (P < 0.0001). In the receiver operating characteristic (ROC) curve analysis (cut‐off for GFR 45 mL/min per 1.73 m2) no significant differences in diagnostic accuracy between all the before mentioned equations were found. Bland‐Altman analysis for the same cut‐off showed that CKD‐EPI creatinine‐cystatin C and BIS2 equation underestimated and CKD‐EPI cystatin C and Simple cystatin C equation overestimated measured GFR. All equations lacked precision. Analysis of ability to correctly predict patient's GFR below or above 45 mL/min per 1.73 m2 showed similar ability for all equations (P = 0.24–0.89). All equations are equally accurate for estimating GFR in elderly Caucasian CKD patients. For daily practice Simple cystatin C equation is most practical.


The relationship between the Catholic Church and the media in Brazil began with the setting up of its own media vehicles; it faced moments of stagnation and nowadays has reached a stage of heavy investment in media projects that relate to an action on identity affirmation, opposing the intense evangelical competition. Besides developing radio and TV networks, Catholics, primarily those linked to the charismatic movement, have been searching for a closer relationship with larger commercial broadcasting groups. The singer priest Marcelo Rossi is a protagonist in this "church popularizing renewal", given a scenery that is both religious and mediatic, marked by the strong presence of Bishop Edir Macedo's Universal Church of the Kingdom of God and its purchase of Record TV Networks. The article deals with the features and the controversy around the Catholic communicational journey.


| There is no doubt that the well-being of cattle, as for other beef species, is a consumer concern. The pre-slaughter period includes a series of potentially stressful interventions to which animals are subject can significantly affect the quality of meat. This is closely related to the disturbances of the physiological state of the animal and its possible reactions to stress. The present study was involved in 38 beef cattle of different ages (<2 years n=19 and >2 years n=19), sexes (male n=20 and female n=18), and breeds (Prim'Holstein n=19, autochthone cattle n=19).The evaluation of stress response of cattle was carried out during their landing in slaughterhouse, before and at the time of slaughter by exploration do some blood biochemical indices (cortisol, testosterone and ACTH) and urinary parameters (cortisol, catecholamines and glucose). The results showed significant breed effect on cortisolemia with a high levels in autochthone cattle compared to Prim'Holstein particularly 20mn before the slaughter (26.8 ng / ml vs 8.6 ng / ml, p <0.05). Similarly, females had high but no significant cortisolemia compared to males before and at bloodletting(21.75 ng / ml vs 18.67 ng / ml at 12h ante mortem, 18.75 ng/ml vs 17 ng/ml at 20 mn before slaughter and 29.25 ng / ml vs. 21.33 ng / ml at bloodletting, P>0.05). Older animals were more reactive to slaughter stress at 20 mn ante mortem and bloodletting (Cortisolemia:21 ng/ml and 29.8 ng/ml) than young, ones who showed more cortisolemia 12h ante mortem (21.2 ng / ml) and also significant difference of testosterone levels (p <0.01) .The urinary parameters did not showed any significant changes during the slaughter preparation stages and bleeding (P>0.05) and they were not significantly influenced by animals characteristics (age, breed and sexe; P>0.05).

Simple Summary Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are a group of tumors with different clinical manifestations, various localizations in the human body, and a particularly wide range of histological types, grades and severities. Their diagnosis and therapeutic management are complex. Current standards are not always effective, and sometimes require modifications. Thus, knowledge about GEP-NENs and approaches for the treatment of these patients in Europe and all over the world are constantly evolving. The aim of this review is to highlight the progress in diagnostics and treatment of GEP-NENs. Special attention is given to GEP-NETs as the most widely reported in the literature. Abstract Neuroendocrine neoplasms (NENs) are an increasingly common cause of neoplastic diseases. One of the largest groups of NENs are neoplasms localized to the gastroenteropancreatic system, which are known as gastroenteropancreatic NENs (GEP-NENs). Because of nonspecific clinical symptoms, GEP-NEN patient diagnosis and, consequently, their treatment, might be difficult and delayed. This situation has forced researchers all over the world to continue progress in the diagnosis and treatment of patients with GEP-NENs. Our review is designed to present the latest reports on the laboratory diagnostic techniques, imaging tests and surgical and nonsurgical treatment strategies used for patients with these rare neoplasms. We paid particular attention to the nuclear approach, the use of which has been applied to GEP-NEN patient diagnosis, and to nonsurgical and radionuclide treatment strategies. Recent publications were reviewed in search of reports on new strategies for effective disease management. Attention was also paid to those studies still in progress, but with successful results. A total of 248 papers were analyzed, from which 141 papers most relevant to the aim of the study were selected. Using these papers, we highlight the progress in the development of diagnostic and treatment strategies for patients with GEP-NENs.


Reliability has been a challenge in the development of NAND flash memory, due to its technology size scaling and bit density improvement. To ensure the data integrity, error correction codes (ECC) with high error correction capability have been suggested. However, much higher costs will be introduced which cannot be supported for cost-limited consumer-level flash memory. Thus, low-cost ECCs are usually applied. In this work, a reliability improvement scheme is proposed for low-cost ECC enabled consumer-level flash memory. The scheme is motivated by the finding that low-cost ECC is able to protect shortened encoded data with improved reliability. This is because that the less the encoded data are, the less the errors will be occurred. With this motivation, a design is proposed to construct the shortened data case for a low-cost ECC when it cannot be able to provide the reliability requirement. Second, two relaxation approaches are proposed to relax the space reduction as it has bad effects on flash memory. A model guided evaluation is finally presented, and the results show that the lifetime can be significantly improved with little space reduction.

ABSTRACT This paper is concerned with the distributed fusion estimation problem for discrete-time linear stochastic systems with measurements coming from different sensors and correlated random parameter matrices in both the state and measurement equations. At each sampling time, the random state transition parameter matrices are assumed to be correlated at the same sampling time with the measurement random parameter matrices of each sensor. Moreover, the random parameter matrices in the observation equations are one-step auto-correlated and cross-correlated between the different sensors. The additive noises are also assumed to be correlated. Under these assumptions, the distributed fusion filter is designed as the matrix-weighted linear combination of the local least-squares linear filters obtained at every single sensor, using the linear minimum variance optimality criterion. A numerical simulation example considering a two-sensor system with randomly delayed measurements is used to illustrate the applicability of multi-sensor systems with correlated random parameter matrices and analyse the performance of the proposed filtering estimators.

This paper focuses on mechatronic systems reliability assessment during the development process phases. Modern technical systems safety requirements are regulated by law, especially the level of safety relevant systems or components. This means it is necessary to decide at early design phase which topology or hardware suites the safety requirements of the system. Therefore the first step is to detect the system impact factors, model the system architecture, and generate a topology tree. One possibility to describe the system architecture is given by the use of the Unified Modeling Language (UML). From the system architecture descriptions MATLAB/Simulink models can be generated. Subsequently the next step is the realization of a reliability-oriented topology, which can be used to consider reliability-oriented aspects.Copyright © 2009 by ASME


The technology of this busting process has the benefit of the lower spectrum of integrated circuits. This allows the addition of additional hardware components to existing chips and upgrades existing features. For example: Add an extra core to a microprocessor or increase hardware resolution for video recording on the phone. Etc. The complex algorithm implementation requires more regional memory (SRAMs) embedded in the hardware. Since memory is well structured compared to logic (gates and cocktails), memory abilities are high. Thus, adding more complex logic increases the likelihood of an error in IS and reduces output. In this article, we will show Re-BISR techniques to eliminate existing memory. We also use the error correction code (ECC) to fix the same error. Both techniques allow us to correct errors and increase the reliability and reliability of the IP. ReBISR can fix many memory errors in the IC and therefore have lower hardware costs than the particular BISR scheme, each of which has a special BISR module. However, Re-BISR has a considerable degree compared to BISR, especially when the REBISR works for each memory. A new version of ReBISR in the future includes the MBIST framework, which can include a lot of algorithms and include a virtual block of memory that is not needed to speed up repairs.


The characteristics of an impulse point spectrometer (so-called chronotron), intended for the analysis of neutral gas in a pressure range of 1 x 10/sup -10/ to 10 mm Hg, are given for the analysis of ions in a non-stationary plasma with a concentration of 1 x 10/sup 6/ to 1 x 10/sup 16/ cm/sup -3/ and for the analysis of ions in a strong magnetic field. The duration of the processes studied may be from 1 x 10/sup -7/ sec up to continuous operation. The extent to which the method can be used is shown on examples of the analysis of currents of molecules desorbed from the surfaces of solids, a study of the mechanism of sorption and catalytic reactions on renewed surfaces using stable isotopes, a study of the interaction of hydrogen plasma with the walls of vacuum systems, a study of the laws of the plasma in impulse discharges, and a study of the passage of atomic bonds through highly ionized plasma.

Double K-shell photoionization of Ne at 5000 eV was observed by recording the KK-KLL Auger-electron hypersatellite spectrum. The measured Auger spectrum is compared with the results of multiconfiguration Dirac-Fock calculations. Shake calculations are used to identify likely multivacancy states produced by photoexcitation or ionization in addition to double-K vacancies, and their calculated Auger spectra are compared with the measured spectrum. The measured relative intensities of hypersatellite and diagram Auger lines are combined with experimental and theoretical determinations of branching ratios from single- and double-K vacancies into final states to determine the ratio of double-to-single K-shell photoionization cross sections to be 0.32(4)%. This ratio is much larger than the calculated high-energy-limit ratio and indicates a large contribution of dynamic electron correlation.


We carried out an experiment on the effects of the colority on the turbidity of colored liquor.The experimental results were as follows:1.the colority only had the minimum effects on the turbidity and then solitary medicinal materials;2.no positive relations between liquor colority and liquor turbidity;3.the colority difference of liquor samples of different production batches was below 0.5,so the colority was not the main factor causing the change of liquor turbidity.(Tran.by YUE Yang)


A simple experimental model of a power generation system was tested in a flowing water tank in order to investigate the performance and feasibility of a small hydroelectric generation system using DE (dielectric elastomer) transducer. The mass of DE material in the power generator module was only 0.1 g. The electric energy generated with a stroke of 10 mm was 12.54 mJ. An electrical energy of approximately 1.5 J per cycle of DE generators can be expected to be generated by scaling up this system, which is capable of being equipped with up to about 100 units of DE transducers. The water velocity was set at 0.30 to 0.70 m/s. This is a small flow, about the same flow as the water in a Japanese garden. This system was driven by Karman vortices in the wake of a cylinder fixed in the water flow. The characteristics of DEs can be utilized to produce electric power effectively. A wing, which is an important part in the generation system to convert fluid energy into mechanical energy, was set behind the cylinder. The wing oscillated due to the pressure caused by Karman vortices, resulting in stretching and contracting of the DE transducers, thus producing electrical power. Experimental results show that an average output power of approximately 31 mW was produced with a generation efficiency of about 66%, when the diameter of the cylinder is 60 mm, the span and chord length of the wing are 120 mm and 30 mm, respectively, the distance between the cylinder and the wing is 170 mm, and the velocity of the water flow is 0.50 m/s.


In the course of modern Chinese development,the Sinicism of Marxism and modernization of China have been the two most important trends.Modernization,as the theme of Chinese modern history,have been the historical mission that Chinese society raised out of its own necessity.As a historical outcome in the pursuit of the modernization of China,the Sinicism of Marxism came into being through the alteration from "following the Euro-American way of development" to "taking Russia as a teacher",which was followed by a surpass of "Soviet model".The realization of modernization has always been the key content of the Sinicism of Marxism.Each development of the Sinicism of Marxism was conducted on the foundation of the cause of Modernization of China,which has been the guideline for Chinese Communist Party in its efforts of constructing a unique modernization road with Chinese socialist characterists in the social development history of human being.


Sulfated zirconia was promoted with alumina and yttria in order to improve catalyst isomerization behaviors. The n-hexane hydroisomerization reaction was carried out in a continuous flow fixed-bed reactor for 80 h on stream to evaluate catalyst reaction stability. The catalyst was characterized by XRD, TGA, H2-TPR, and NH3-TPD technologies in order to investigate the crystalline structure, sulfur content, reduction behavior, and acidity of the catalyst. It was proved that the addition of alumina and yttria obviously increased the sulfur content on the fresh catalyst and also markedly stabilized the sulfur species on the used catalysts. Thus, the modified catalyst possessed the better stable activity and selectivity although the addition of promoter could not enhance the isomerization activity. The crystalline structure of sulfated zirconia, acidity, and sulfur content only showed a limited influence on the isomerization activity of the catalyst. This work would have potential use to prepare an ideal catalyst for a commercial alkane hydroisomerization unit.

Large scale model of sand funnel was carried out to optimize the layout, and to form stable 3D votex to separate water and sediment for continuous discharging of sediment which is achieved by taking proper hang luniform board,adjusting pier,funnel diameter,layout etc.The larger the critical diameter of sediment,the smaller the sacle of funnel is applied so as to strengthen the vortex to discharge sediment with less water consumption.The smaller the critical diameter of sediment,the bigger the sacle of funnel is applied so as to keep proper voetex to avoid fine particle to mix with diversion water.A optimized funnel with diameter of 60 m was studied,and the results show that the sediment with 0.1 mm diameter or larger was discharged more than 90% of its amount under 40~50 m3/s,while the water consumption is lass than 10%,so the effect is very satisfactory.


During the last decade, two angiotensin converting enzyme (ACE) inhibitors, captopril and enalapril, have become accepted into clinical practice and are regarded as effective treatments for hypertension and congestive cardiac failure.' A third agent, lisinopril, had recently become available and others are likely to be introduced in the near future. It is clear, therefore, that more patients, who are being treated with these drugs, will present for elective and emergency anaesthesia than has previously been the case. Physicians and anaesthetists must be aware of the associated implications. Severe hypertension is undoubtedly a risk factor for anaesthesia, especially if it is poorly controlled.2 Adequate control of hypertension, smooth anaesthesia, choosing agents for their desired cardiovascular properties, and awareness of potential drug interactions are essential if the risk of adverse events is to be minimized. Anaesthetic agents generally interact with antihypertensive drugs in a predictable fashion and such interactions are usually of little consequence. ACE inhibitors may pose special problems by virtue of their modes of action, namely: reduction in angiotensin II, and aldosterone formation, blockade of the effects of renin and inhibition of bradykinin breakdown. Despite the initial reduction in aldosterone levels these often return to normal and the natriuretic effect may be due to the reduction in angiotensin II. Plasma volume has generally been found to be normal although cardiac preload is reduced.4 However, it is important to realize that the renin response to haemorrhage or hypotension will be greatly attenuated and therefore normal homeostatic reflexes will be impaired. In addition, the 'normal' increase in blood pressure with surgical stimulation corresponding to an increase in renin activity will be modified.' It has come to our attention that many anaesthetists, especially junior anaesthetists, do not appreciate the potential problems associated with these agents and this is due to the paucity of clinical trials or infrequent case reports on ACE inhibitors and anaesthesia. Recently we have seen cases of severe, unexpected hypotension at induction of anaesthesia in well controlled hypertensive patients on monotherapy with captopril. This hypotension was persistent and only reversed by the infusion oflarge volumes of fluid. ACE inhibitors used to be reserved for patients with severe hypertension but are now prescribed increasingly by general practitioners for any patient with hypertension despite their not being recommended as first line treatment for hypertension.' The increasing use of ACE inhibitors as monotherapy for hypertension may increase the incidence of such adverse anaesthetic occurrences. On the positive side, when controlled hypotension is desirable during general anaesthesia, ACE inhibitors may contribute and reduce the requirements for other agents such as sodium nitroprusside,6 and thus reduce the potential for cyanide toxicity during long operations. The use of ACE inhibitors in patients with congestive cardiac failure is also increasing due to their beneficial effects on symptomatology and a reduction in mortality.7 However, hypotension may be a problem, particularly with enalapril,8 with the potential for myocardial ischaemia and this again may also be increased during induction of anaesthesia. Compared with other vasodilators, ACE inhibitors are more likely to be associated with hypoperfusion9 particularly so when their use is preceded by a diuretic. This compounds the fact-that they are, in any case, less likely to retain fluid and could conceivably increase the magnitude of the reduction ofblood pressure that may occur at induction ofanaesthesia. The blood volume is relatively reduced when these patients are compared with those treated with other vasodilators. Hypotension with captopril has been shown to be more likely if the patient is sodium and volume depleted'" and therefore prolonged fasting before elective anaesthesia may increase the incidence of hypotension. In conclusion, although ACE inhibitors are therapeutically effective, their widespread use may contribute to anaesthetic problems (and possibly to


INTRODUCTION Advancements in operational life of catalysts based on noble metals supported on activated carbon are being tested for use in advanced life support applications, and possible later space station utilization. Activated carbon-supported metals such as platinum, palladium, and ruthenium provide the highest level of activity per unit weight/volume for oxidation of organic contaminants to CO2, resulting in the highest quality product water available. The technical approach of this project is to improve the physical stability of these materials by applying novel oxidation-protection treatment technologies to the catalysts to prevent oxidation of the activated carbon support during reactor operation. The technology also has application to air treatment (e.g. trace contaminant control) and a number of industrial processes. Reduction in expendable requirements, lowered power requirements due to lower operating temperatures, and elimination of potential particulate generation from the catalyst substrate are the key technical goals.


In 2016 Kamianets-Podilsky Architectural and Archaeological Expedition of the Protective Archeology Department of the Institute of Archeology NUAS discovered remains of the construction on the stone foundation on the south-east part of the Polish Market Square. The big amount of clay pipes, painted porcelain, earthenware and clay coffee cups, architectural peculiarities of the building and literary pieces of evidence let interpret the remains as a coffee house. Findings from the pit 2 are introduced as the new types of ceramics. The majority of the pottery discussed: pots, jugs, «makitras», bowls, and plates — is of the local origin. The analogies to these types of pottery are largely represented in the 17th century material complexes on the territory of Ukraine. Bowls and bailers are of the Turkish origin. These types of pottery are found among the artifacts excavated on the territories of the Ottoman Empire fortresses in Belgrad, Akkerman, and Izmail.
The article uncovers the peculiarities of everyday living of the citizens of Kamianets-Podilsky and Turkish garrison in Podolia Eyalet (1672—1699).


We use Pseudo Quantum Electrodynamics to study massive (2+1)D Dirac systems interacting electromagnetically via a U(1) gauge field in (3+1)D. It was recently found in Ref. [1], that an interaction-induced Quantum Hall Effect (QHE) and Quantum Valley Hall Effect (QVHE) occur in these systems, when considering a two-component fermion representation. Here, we study the corrections to these effects when coupling the fermions to a (2+1)D massive scalar field via a quartic interaction. We find no correction to the QHE and a non-universal correction to the QVHE, which depends on the ratio of the fermion and scalar-field masses.


In recent years, postmodernism and complexity have been discussed intensively in the social sciences. Postmodernism, as a concept, has been widely discussed from the organization theory perspective. It's expected that complexity theory will make important contributions to the organization research. In this study, post‐ modernism and complexity theory, which is implied to have strong connections with each other in the literature, are examined as well as being positioned at the Burrell and Morgan framework. Results of the study show that postmodernism and complexity theories are relatively different from each other. As postmodernism is generally positioned at the radical‐humanist section, complexity theory is mostly positioned at the functionalist section.


Stability of mixed ligand complexes(MAL) have been determined by potentiometric pH titrations in v/v dioxan water medium. The ternary complexes are significantlystable due to intramolecular interligand interactions between indole residue of A and non-coor dinating side groups of L. The relative stabilities of Cu(II) and Ni(II) complexes have been explained on the basis of new concept of interaction between metal orbi tal and non-coordinating group of the two ligands.


Modulation of local calcium levels appears to be an important regulatory mechanism for endothelial function. Localized spontaneous endothelial calcium oscillations have recently been described within the myoendothelial projection. Interestingly, calmodulin‐dependent protein kinase II (CaMKII) is involved in endothelial function and is characterized by its ability to decode oscillatory calcium signals into specific outcomes. The aim of this study was then to determine the activation of CaMKII by calcium pulsars in endothelial cells from mesenteric arteries and their alteration in hypertension. qPCR experiments suggest that all four CaMKII isoforms (α, β, δ and γ) are expressed in mesenteric arteries but their expression was significantly decreased (27–57%) in hypertensive animals. Immunohistochemistry confirmed that all isoforms are expressed in mesenteric endothelium and were homogeneously distributed in normotensive animals. However, hypertension is correlated with a distribution of endothelial CaMKII in clusters. Ca2+ pulsars agonists appear to stimulate clustering of CaMKII as evidenced by immunohistochemistry. This data suggest that endothelial CaMKII is activated by Ca2+ pulsars and that this mechanism is altered in hypertension.

Demand Response (DR) programs and markets are being studied and developed to help increasing the efficiency of the generation especially with high penetration of renewable energies into the electric grid. This talk is divided into two main sections as they are being studied in the Renewable Energy Design Laboratory (REDLab) of the University of Hawaii at Manoa. First we present a theoretical framework of the DR market followed by a realistic testbed to verify the method.


Potential promoting effects of α‐linolenic, linoleic and palmitic acids were investigated in a two‐stage urinary bladder carcinogenesis model. In experiment 1, male F344 rats were given 0.05% N‐butyl‐N‐(4‐hydroxybutyl)nitrosainine (BBN) in their drinking water for 4 weeks and then basal diet containing 10%α‐linolenic, 10% linoleic or 10% palmitic acid along with 0.2% butylated hydroxyanisole (BHA) as an antioxidant for 24 weeks. The development of tumors in the urinary bladder was not increased by treatment with any of the fatty acids. In experiment 2, male F344 rats were given 10%α‐linolenic, 10% linoleic or 10% palmitic acid along with 0.2% BHA in their diet for 8 weeks without prior BBN treatment. The administration of fatty acids was not associated with any increase in the 5‐bromo‐2′‐deoxyuridine labeling index of the urinary bladder epithelium. Serum and/or urine fatty acid Ievels increased in the cases of α‐linolenic and linoleic acid treatments, but not with palmitic acid. Under the present experimental conditions neither the two polyunsaturated nor the one saturated fatty acid exerted any promoting effect on urinary bladder carcinogenesis.

The results of calculation in solution are in better agreement with experimental values than in gas phase.


Objective To analyze the correlation between body mass index(BMI) and primary hypertension and blood glucose,blood uric acid and blood lipid among mid- aged people in Shenzhen City. Methods Among 4159 subjects from 30 to 49 years old collected by cluster sampling,blood pressure,blood glucose,blood uric acid,total cholesterol( TC),triglyceride( TG),low- density lipoprotein- cholesterol( LDL- C),and high- density lipoprotein- cholesterol( HDL- C) were detected. TC / HDL- C ratio and BMI were calculated. Body index of different hypertension level groups and the correlation between body index and biochemical metabolism were investigated. Results BMI,blood glucose,blood uric acid,TC,TG,LDL- C and TC /HDL- C in primary hypertension group are all significantly higher than those in control group( P 0. 01). There are statistical differences between the distributions of BMI in the two groups. Marked positive correlation between BMI and blood glucose,blood uric acid,or TC / HDL- C existed in all the total,normal and hypertension group. Conclusion BMI is related not only to the morbidity of primary hypertension,but also to the biochemical metabolism in mid- aged hypertension population.


This paper analyses the optimal hedging decisions for risk-averse producers facing crop risk, assuming crop yield insurance futures and options are available. The first-best optimal hedge requires either a futures position or an option position proportional to the regression coefficient of individual yield on aggregate yield depending on whether the financial markets are unbiased or biased. Using yield data for a sample of wheat producers in France, the producers' hedge ratios are derived. The individual crop risk is shown usually to contain a large systemic component. These new hedging instruments are usually more effective to reduce farm yield variability than individual yield contracts. Copyright 2000, Oxford University Press.


Phenylacetaldehyde was tested by itself in 1965 and with the female cabbage looper sex pheromone in 1971 to obtain additional data on its attractancy to Tichoplusia ni (Hubner), and other lepidopterous species. Phenylacelaldehyde has been previously reported to be lightly attractive to male and female cabbage looper moths. The present tests showed extreme variation in its attractiveness to females, and its attractiveness 10 males could not he ascertained precisely because of the presence of live females (captured) in the traps. Addition of phenylacetaldehyde to the pheromone traps enhanced the total catch. Screen-cage traps were more efficient than were can-type traps in catching moths.

This paper develops an equilibrium model with a housing collateral constraint in which rational agents are uncertain about the collateral price process. Bayesian learning by agents can endogenously generate booms and busts in collateral prices and significantly strengthen the role of the collateral constraint as an amplification mechanism through the interaction of agents' price beliefs, price realizations and credit limits. Over-optimism or pessimism is fueled when a surprise in price expectations is interpreted partially by the agents as a permanent change in the parameters governing the collateral price process and is validated by subsequently realized prices. The learning model can quantitatively account for the recent US boom-bust cycle in house prices, household debt and aggregate consumption dynamics during 2001-2008. The paper also demonstrates that the leveraged economy with a higher steady state leverage ratio is more prone to self-inforcing learning dynamics.


A new approach based on BP neural network integrated with genetic algorithm for fitting of micro-drill's main lips is presented. The network structure is designed according to fitting equation, coordinates of micro-drill sampled points and constant 1 are taken as 3 inputs of network, 1 output is obtained, and the square of errors between the output and constant 0 is taken as performance index. Weights between input neurons and output neuron are tuned in the light of gradient descent mean, and stable weight values are obtained until the desired performance index is reached. In order to obtain global optimal solution, genetic algorithm is integrated in the linear BP NN, and expression coefficients of main lips line can be solved according to the weigh. Thus chips depth of micro-drills main lips can be measured easily. The approach has advantages of algorithm simple and higher precision over conventional approaches such as least square means and so on.


This paper presents the architecture and implementation in which two computer codesTOUGH2 and GeoCrack3D are linked. A fully coupled thermal-hydrologic-mechanical (THM) analysis of multiphase fluid flow, heat transfer, and deformation in a porous rock can be carried out. The codes are simultaneously executed to run as one module T2STR. The forward coupling is achieved by using the thermal, hydrostatic and poroelastic effects in the effective stress calculations. The backward coupling includes the effect of strain on the fluid flow and also includes the corrections in porosity, permeability, and capillary pressure as function of mean effective stress.


A statistical approach is taken to present and analyze large amounts of physical and radiometric temperature data for structural materials as well as weather data collected over a period of several years at sites in both the United States and Europe. Diurnal temperature curves are presented as a function of time-of-year, surface material type, and surface orientation. Empirical temperature prediction models for different surface types as a function of weather parameters are developed for a given set of data to demonstrate the utility of maintaining large temperature/weather data bases in support of first-principles thermal modeling.


The increasing demands of multifunctional organic electronics require advanced organic semiconducting materials to be developed and significant improvements to be made to device performance. Thus, it is necessary to gain an in-depth understanding of the film growth process, electronic states, and dynamic structure-property relationship under realistic operation conditions, which can be obtained by in-situ/operando characterization techniques for organic devices. Here, the up-to-date developments in the in-situ/operando optical, scanning probe microscopy, and spectroscopy techniques that are employed for studies of film morphological evolution, crystal structures, semiconductor-electrolyte interface properties, and charge carrier dynamics are described and summarized. These advanced technologies leverage the traditional static characterizations into an in-situ and interactive manipulation of organic semiconducting films and devices without sacrificing the resolution, which facilitates the exploration of the intrinsic structure-property relationship of organic materials and the optimization of organic devices for advanced applications.

Advance communication systems such as fifth generation (5G) and 5G+ expect to deploy the security solutions for securing the communication networks. Finding the optimum size of the security gap is a challenging problem in the large scale networks. In this paper, the parity check matrix (H) of low-density parity check (LDPC) considered for determining the security gap is analyzed with the higher rate LDPC coding schemes and different size of frames. Here, optimum LDPC decoding is considered as a method. Especially, the physical layer is investigated with H and two different high-rate codes and simulated to find the optimum size of security gaps for better security. Also, non-orthogonal multiple access (NOMA) is employed to enhance the security solution. Thus, optimum security gap is possible when suitable NOMA is employed in the physical layer of the 5G communication system. As expected in this research conclusion, simulation results show that the security gap decreases when frame size is increased.


The line widths of the protonated aromatic carbons depended strongly on temperature. A motion that could cause such temperature-dependent line widths is ring flipping. The results are consistent with an activation energy of 8-9 kcal/mol. Three-fold rotation of the methyl groups is adequate to explain the width of the signals from the methyl carbon at low temperature. However, isotropic motion of the methyls with a temperature-dependent amplitude, in addition to methyl rotation, is not ruled out

The paper deals with numerical modeling of the wave processes in a three-phase line. The substantial part of the computer program is solution of a system of six wave equations by means of the Wendroff approximation. The computations allow determining overvoltage and overcurrent phenomena occurring at a strike of the lightning to the line or at various fault states on lines. This information represents a basis for safe dimensioning of lines and their insulation systems as well as setting of its overvoltage and overcurrent protective devices.


In this paper the progressive collapse potential of building structures designed for real construction projects were evaluated based on arbitrary column removal scenario using various alternate path methods specified in the GSA guidelines. The analysis model structures are a 22-story reinforced concrete moment frames with core wall building and a 44-story interior concrete core and exterior steel diagrid structure. The progressive collapse resisting capacities of the model structures were evaluated using the linear static, nonlinear static, and nonlinear dynamic analyses. The linear static analysis results showed that progressive collapse occurred in the 22-story model structure when an interior column was removed. However the structure turned out to be safe according to the nonlinear static and dynamic analyses. Similar results were observed in the 44-story diagrid structure. Based on the analysis results, it was concluded that, compared with nonlinear analysis procedures, the linear static method is conservative in the prediction of progressive collapse resisting capacity of building structure based on arbitrary column removal scenario.


Basic Science Process Skills (BAPS) are some of the scientific skills used to obtain, process, build and apply scientific theories. Basic science process skills are not only useful in learning science but also for students' daily lives.

Ultra water-repellent films were prepared by using rf PECVD. Relationships between the rf power and water repellency, morphological and chemical properties were investigated. Moreover, the growth process of ultra water repellent thin films was evaluated by using FESEM. The experimental results showed that surface morphology of the films strongly depends on the rf power, and that increasing the rf power made it possible to from ultra water-repellent films. At the first stage of the growth, the nano-clusters were deposited randomly on the substrate surface. These clusters were originated from a polymerization process in the gas phase and deposited on the substrate. When the film was deposited for several tens of seconds, the nano-clusters showed a tendency to form chains or islands, which means the clusters must have a spatial preference. Finally, these films have particular nano-textures with nano-scale pores of a few hundreds of nanometers in diameter among the rough web-like structure of the nano-cluster agglomerates


In Situ Characterization of Soil Properties Using Visible Near-Infrared Diffuse Reflectance Spectroscopy. (May 2006) Travis Heath Waiser, B.S., Texas A&M University Chair of Advisory Committee: Dr. Cristine Morgan Diffuse reflectance spectroscopy (DRS) is a rapid proximal-sensing method that is being used more and more in laboratory settings to measure soil properties. Diffuse reflectance spectroscopy research that has been completed in laboratories shows promising results, but very little has been reported on how DRS will work in a field setting on soils scanned in situ. Seventy-two soil cores were obtained from six fields in Erath and Comanche County, Texas. Each soil core was scanned with a visible nearinfrared (VNIR) spectrometer with a spectral range of 350-2500 nm in four different combinations of moisture content and pre-treatment: field-moist in situ, air-dried in situ, field-moist smeared in situ, and air-dried ground. Water potential was measured for the field-moist in situ scans. The VNIR spectra were used to predict total and fine clay content, water potential, organic C, and inorganic C of the soil using partial least squares (PLS) regression. The PLS model was validated with data 30% of the original soil cores that were randomly selected and not used in the calibration model. The root mean squared deviation (RMSD) of the air-dry ground samples were within the in situ RMSD and comparable to literature values for each soil property. The validation data set had a total clay content root mean squared deviation (RMSD) of 61 g kg and 41 g kg for the


In the design of a reflecting mirror used in the space optical system,many techniques were used to reduce the influence of temperature shift.But because of the direct irradiation of the sun,the mirror temperature environment was very severe and heat distortion analysis should be conducted.To do that,this paper first discussed the general procedure of conducting heat distortion analysis.Two approaches for the temperature mapping problem,which was the key point of the procedure,were then compared.The heat-transfer mapping method was used for this problem and a heat distortion analysis was conducted.The results show that the PV and RMS values of the reflecting mirror are consistent with the experimental data and the heat-transfer mapping method is useful in the problem.

In this paper it is considered that the relationship between nominal exchange rate and prices depends on the nature of the shocks impacting the economy. In order to identify the sources of nominal exchange rate and relative price fluctuations we impose long-run restrictions on the dynamics of these variables through a 2-variable and 3-variable SVAR, respectively. This methodology is applied to data on the Spanish economy and find that supply and real demand shocks move nominal exchange rates and relative prices in opposite directions. Nominal shocks, however, move both variables in the same direction. Thus, in this case, only under nominal shocks may exchange rate depreciations fuel inflation.


The polycondensation of bis(4-mercaptophenyl) sulfide (BMPS) with bis(4-chloro-3-nitrophenyl) sulfone (BCNPS) was examined using various organic or inorganic bases in mixed solvents ofN-methyl-2-pyrrolidone (NMP) with water or in plain water. The reaction of BMPS with BCNPS proceeded smoothly to give the corresponding polysulfide in mixed solvents of NMP with water at 60 °C using 1,8-diazabicyclo[5.4.0]undecene-7 as a base, although the rate of the reaction decreased gradually as the water in the solvent increased. Polysulfide can also be obtained by reaction in plain water using appropriate organic bases such as tripropylamine (TPA) or quinoline. The polysulfide with a number-average molecular weight of 45,100 was synthesized in 62% yield when the reaction of BMPS with BCNPS was performed using TPA as a base at 60 °C for 48 h in plain water.

This paper presents a realization of integer fast lapped biorthogonal transform (FLBT) via applications of discrete cosine transform (DCT) matrices and dyadic-valued factors for lifting coefficient blocks. It is obtained by using the block-lifting factorization as our previous work and easy matrix manipulations. The proposed FLBT has higher coding performance and fewer rounding operations than the conventional methods. The practicality of the proposed FLBT is validated through lossy-to-lossless image compression (coding) simulation which unifies lossy and lossless image coding.


Abstract This study reports the preparation of a new CdS&NiO/Ni2O3 photocatalyst having efficient and stable photocatalytic performance. The aim was to block the photocorrosion of CdS with maintaining photocatalytic activity. The prepared CdS and NiO/Ni2O3 particles were in the form of nanorods and nanoballs, respectively. Diffuse reflectance spectra (DRS), X-ray diffraction (XRD), ultraviolet-visible light (UV–vis), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), Raman analysis, electrochemical impedance and photoluminescence analysis were performed to evaluate structural, morphological and optical properties and their effect on photocatalytic activity. CdS&NiO/Ni2O3 catalysts absorbed visible light and enhanced charge separation than that of CdS and NiO/Ni2O3. The catalytic performance of the samples was tested on Congo red. The optimal content of CdS&NiO/Ni2O3 was observed in CN3 sample. XPS results of defective NiO with different oxygen species showed powerful photocatalytic activities. These prepared photocatalysts need to be explored further in the decomposition of various environmental pollutants. Graphical Abstract


The two nitrogen and one oxygen bearing tridentate ligand (H2pytzo-2, 6-bistetrazolate pyridine oxide) have been prepared by oxidation of 2, 6-bistetrazolate pyridine and then coordinated with transition metals. The complexes of [M(pytzo)2](NHEt3)2, (M= Rh, Ir) were synthesized in good yields (50% for Rh and 47% for Ir). UV, FT-IR, 1 H NMR, XRD and elemental analysis were used to determine the structure of complexes. The tetrazole groups greatly influence the absorption spectra of complexes towards the visible region (362.2nm for Rh and 357nm for Ir). Further the extended unsaturation, lone pairs and π-excessive nature of ligand promotes the fluorescence spectra upto 560nm for Rh complex and 558nm for Ir complex. The antibacterial activity results showed that K. pneumoniae and S. aureus showed maximum response followed by E. coli and B. cereus, respectively. The maximum zone of inhibition of complexes was observed at 6mg/ml concentration viz; K. pneumoniae, 13.0±1.73mm for iridium complex and S. aureus, 12.3±0.57mm for rhodium complex. Hence 2, 6-bistetrazolate pyridine oxide (H2pytzo) ligand triggers the vital applications in the complexes were useful both in biological as well as solid state devices.


IZA DP No. 14220 MARCH 2021 Resilience to Disaster: Evidence from Daily Wellbeing Data* As the severity and frequency of natural disasters become more pronounced with climate change and the increased habitation of at-risk areas, it is important to understand people's resilience to them. We quantify resilience by estimating how natural disasters in the US impacted individual wellbeing in a sample of 2.2 million observations, and whether the effect sizes differed by individualand county-level factors. The event-study design contrasts changes in wellbeing in counties affected by disasters with that of residents in unaffected counties of the same state. We find that people's hedonic wellbeing is reduced by approximately 6% of a standard deviation in the first two weeks following the event, with the effect diminishing rapidly thereafter. The negative effects are driven by White, older, and economically advantaged sub-populations, who exhibit less resilience. We find no evidence that existing indices of community resilience moderate impacts. Our conclusion is that people in the US are, at present, highly resilient to natural disasters.

Fluorescence induction curves of Tradescantia fluminensis L. leaves acclimated to growth light of different intensities have been studied. Plants grown at low light (LL, 50–125 μmol photons m-2 s-1) and high light (875–1000 μmol photons m-2 s-1, HL) revealed different patterns of chlorophyll (Chl) a fluorescence. Chl fluorescence was measured by the PAMfluorometry method, using blue actinic light (455 nm, BAL) or red actinic light (630 nm, RAL). In the case of HL samples, non-photochemical quenching (NPQ) of Chl a fluorescence depended on actinic light intensity, but for all that we did not observe any difference between the samples illuminated by BAL or RAL. Otherwise, for leaves grown at LL conditions, we observed that BAL induced markedly higher NPQ than RAL. For both types of samples, photochemical quenching of fluorescence decreased with an increase in the intensity of actinic light, but in most cases was different upon the action of BAL and RAL. After switching the actinic light off, the NPQ level gradually decreased. The residual value of NPQ (qI), registered in the dark 30 min after ceasing AL, was dependent on the illumination pre-history. Maximal level of qI was observed in LL plants illuminated by BAL. The data obtained are discussed in the context of the problem of the protection of plant photosynthetic apparatus against solar stress.

This paper discusses the concept of semantic repetition in literary texts, that is, the recurrence of elements of meaning, possibly in the absence of repeated formal elements. A typology of semantic repetition is presented, as well as a framework for analysis based on the use of threaded Directed Acyclic Graphs. This model is applied to the script for the movie Groundhog Day. It is shown first that semantic repetition presents a number of traits not found in the case of the repetition of formal elements (letters, words, etc.). Consideration of the threaded DAG also brings to light several classes of semantic repetition, between individual nodes of a DAG, between subDAGs within a larger DAG, and between structures of subDAGs, both within and across texts. The model presented here provides a basis for the detailed study of additional literary texts at the semantic level and illustrates the tractability of the formalism used for analysis of texts of some considerable length and complexity.


Moving Japan can be a complex, challenging experience. Not only is the language barrier daunting, but life there often appears about as foreign as it can get. Why are people bowling to vending machines? Why did they laugh at your feet after a visit to the lavatory?

AFRICAN DEVELOPMENT Abstract: There are very real concerns over uncertainty in the country (but also in the world) currently South Africa faces prevailing challenges in the economy and business markets that precede but are not unaffected by the COVID-19 pandemic and the Government-led containment measures that have been implemented - as undeniably and understandably necessary as the measures are to safeguard the lives of citizens - to combat the spread of the virus But it is often darkest before the light - and as history has taught us, some of the most difficult periods have led to great innovations, new approaches and renewed opportunities


This research is a case study conducted at PT. Bondi Syad Mulia, which is a galvanishing services company. Production planning at PT. Bondi Syad Mulia combined with production department, so that the work does not focus and cause some problems in production planning. The proposed planning system is set up the PPIC department, so that production planning does not interfere with affairs that must be done by the production department. Another issue that arises is the production delays because there is do not have a good system of production scheduling. Determine the right scheduling for a company is very important, but not easy, especially for a service company that manufactures a wide range of products. This thesis aims to get the system scheduling to minimize makespan, thus increasing the amount of output produced. The method used to achieve these criteria is Algorithm Campbell, Dudek, and Smith (CDS) and Shortest Processing Time method (SPT). CDS scheduling algorithm results provide several alternative job sequences that generate makespan value is almost the same, but there is a job sequence that produces the smallest makespan value compared to other alternative job sequences.


The utility model discloses a pair of elastic cloth shoes and solves the problems that the season adaptation range is narrow and the service life is short because the surfaces of the prior elastic cloth shoes adopt a single cloth structure. The elastic cloth shoes have the structure that the elastic cloth shoes comprise soles and uppers connected with the peripheries of the soles, and elastic belts are arranged at the ports of the uppers. The elastic cloth shoes are characterized in that the uppers comprise outer surface layers and inner surface layers, the outer surface layers and the inner surface layers are bonded together, and flanges are formed at the peripheries of the ports of the uppers.


What rights do retarded children have not to be institutionalized? What rights do retarded people have to aggressive medical treatment that will help prolong their lives? These are questions that the Supreme Court has been asked to decide in recent years. This article examines how the court has responded to these issues and what these responses mean for public policy toward people with retardation. It concludes that the court may have been guided by negative social attitudes when it considered these issues.


The activities of a veterinarian are often broadcasted in a limited way, creating a stereotype of a profession that regards only about taking care of dogs and cats, not linking it to quality and safety of animal origin food. Besides that many veterinarians are unaware or do not understand their fi elds and / or their importance in public health. It is aimed, with this article, to rethink, to inform and to change concepts about performance and importance of veterinarians in the safety and quality of animal origin food, particularly in the milk chain (which is target of adulteration and contamination by chemicals and pathogens), demonstrating that this professional is the main responsible for the orientation and supervision of milk and its derivatives ensuring that they have quality and are safe for consumption.


The study of the proximate analysis on the leaves of Vitex negundo L. (VN) was done to gain the preliminary data of the anti-proliferative properties on cancer cell lines. Aqueous and organic extracts of the leaves of VN were used to identify its cytotoxic effect on six types of cancer-origin and normal cells, namely hormone-dependent breast cancer cell line (MCF-7), non-hormone-dependent breast cancer cell line (MDA-MB-231), ovarian cancer cell line (Caov-3), cervical cancer cell line (HeLa), liver cancer cell line (HepG2) and human foreskin fibroblast cell line (Hs27). The anti-proliferation activities of these extracts were investigated by employing colorimetric MTT (3-(4,5-dimethylthiazol-2-yl)2,5 diphenyltetrazolium bromide) assay through time periods of 24, 48 and 72 h. Preliminary results showed that the methanol extracts had significant effects (p<0.05) on MDA-MB-231 with IC50 values 65.38 μg/mL. The nutritional composition of the leaves provides a strong basis for emphasizing the nutritional value of Vitex negundo L.


This paper will highlight the innovative facility upgrades and modeling techniques that will be utilized to produce hardware-in-the-loop simulations to support both the development and production phases of this Pre-Planned Product Improvement program.


Scientific research in the United States could receive a large increase in federal funding--up to 100 billion dollars over five years -- if proposed legislation entitled the Endless Frontiers Act becomes law. This bipartisan and bicameral bill, introduced in May 2020 by Senators Chuck Schumer (D-NY) and Todd Young (R-IN) and Congressmen Ro Khanna (D-CA) and Mike Gallagher (R-WI), is intended to expand the funding of the physical sciences, engineering, and technology at the National Science Foundation (NSF) and create a new Technology Directorate focused on use-inspired research. In addition to provisions to protect the NSF's current missions, a minimum of 15\% of the newly appropriated funds would be used to enhance NSF's basic science portfolio. The Endless Frontier Act offers a rare opportunity to enhance the breadth and financial support of the American research enterprise. In this essay, we consider the benefits and the liabilities of the proposed legislation and recommend changes that would further strengthen it.


Every college and university that has more than a handful of computer terminals most certainly has a Help Desk, whether they're aware of it or not. If there is any single department or office that oversees computer usage, and answers user questions, then they function in some way as a Help Desk. Some are more organized and developed than others, but the basic concept is the same: assist the computer user. Obviously, how involved this Help Desk service becomes depends on the size, available resources, and goals of the institution.


1. They may become ideologically more conservative.' 2. They may have burdened themselves with such substantial obligations as installment buyers that they are both less willing and less able to face the prospect of a strike.2 3. Because of the increased rate of formation of new households, the number of full-time or part-time wage earners, whose income can be pooled in an emergency, will be less. Moreover, the high birth rate reduces the opportunity for many wives to earn supplementary incomes.3 4. The above points lead to a weakening in labor's bargaining position.4


Thermoplastic elastomers (TPEs) blends have been developed offering various advantages and required no state-of-the-art processing machinery, while scrap and rejects are recyclable. The use of thermoplastic and elastomer however posses several limitations due to the increasing prices of plastics and natural rubber over the past few years. Hence, effort has been taken by combining kenaf natural fibres with thermoplastic elastomers. In this project, 20 vol% kenaf fibre was incorporated into thermoplastic elastomer. Two types of impact modifier were blended with polypropylene (PP) namely; thermoplastic natural rubber (TPNR) and polypropylene/ethylene-propylene-diene-monomer (PP/EPDM). Both composites were produced via double melt blending method using Haake internal mixer before they were injection moulded. The ratio of thermoplastic:elastomer was 70:30 for both polymer blends. Maleic anhydride polypropylene (MAPP) was added as a compatibilizer between matrix and reinforcement. The tensile strength for TPNR was about 12% higher than the PP/PPDM matrix. The present of kenaf fibre (KF) and MAPP however has significantly increased the tensile strength of PP/EPDM composite by approximately 81% while only 55% increment attained in TPNR-KF-MAPP as compared to unreinforced TPNR. Flexural properties and impact strength are greatly improved for treated kenaf fibre composite. MAPP has successfully forming a linkage bridge between kenaf fibre and polymer matrix thus enhanced of strength and stiffness of treated thermoplastic elastomer composites. Scanning electron micrographs (SEMs) revealed that the improvement achieved in mechanical properties was due to the interaction between both matrix systems and kenaf fibre.


In an increasingly globalized world, civil war in one country can have impacts around the world. Here, migrants arrive on the island of Lesbos in Greece. In 2015 the Syrian civil war produced a massive refugee crisis that flooded Europe with requests for asylum. The political and economic effects of this movement of people were huge, burdening the weak Greek economy, leading to greater support for anti-immigrant parties in many European countries and influencing the successful British vote to leave the European Union.

the Japanese way of thinking. The aesthetic element greatly stressed by Prof. Kosaka might also belong to this practical, empirical, intuitive characteristic of the Japanese. Another main trait of the Japanese is his tendency toward harmony, concord, wa. This element described by Yukawa as the tendency to sidestep as far as possible any kind of confrontation, by Nakamura as the spirit of tolerance, and by Kawashima Taketoshi, a scholar of the sociology of law, as the concept of social obligation without the counterbalancing notion of right. This feature might also be described as the tendency to minimize both practical and intellectual cleavages and confrontation, resulting in an intellectual eclecticism combining points of view which are incompatible in strictly logical precision, and in practical tolerance which does not always solve the real tensions. The religious attitudes are studied in detail by D. T. Suzuki, Sakamaki Shunzo, Hanayama Shinso, Kishimoto Hideo and Ueda Yoshifumi. Eclecticism, flexibility, this-worldliness, apprehension of the Absolute in the phenomenal world, clear distinction between ethics and religion, almost identity between aesthetic experience and religious experience, all these elements recur frequently. In Japanese ethics there is no attempt to find a philosophical, metaphysical or religious basis for ethics. One would have liked a longer treatment by Kishimoto of the affirmation that the Japanese religions during the past century have not modernized themselves because of the indiscriminately accepted belief among the Japanese that modernization meant Westernization. For the Japanese religions, it was fatal to become Westernized; and since modernization and Westernization were thought of as one, by resisting Westernization, the Japanese religions unconsciously resisted modernization too. This is a great book, extremely useful for a comprehensive approach to Japanese culture. One has the impression, however, that quite often the element of change in Japanese culture has not been stressed enough. Some elements have been described as if they were unchanged and unchangeable. At other times one feels that what is described as the fundamental trait of the Japanese is just one element JOURNAL OF ASIAN STUDIES

Objective To introduce a new approach for treatment of mandibular angle hypertrophy-transoral approach three point localization curve shape osteotomy. Methods 68 patients with mandibular angle hypertrophy were choosed to be operated by transoral approach. Tissues around mandibular angle was dissociated extensively. Set the intersection of mandibular angle ascending branch anterior border decurrent extension line and the inferior border of mandible as point A, the intersection of parallel lines of biteplane and the posteromarginal of mandibular angle ascending branch as point B, the original mandibular angle as point C, the new mandibular angle as point D, to set a perpendicular which goes through point C on the line AB, then to set point D on the perpendicular above point C about 1 or 2 cm, and finally to cut the bone following the curve which goes through point A,D,B. Results No complications such as injury of facial nerve, oral lips numbness, bone fracture and facial asymmetry. 97% of patients were satisfied. Conclusion To compare with other methods, the new method of the three point localization curve osteotomy has much more advantages, it's safer and more effective and it's worthy of widely spreading.


(±)-(3R*,4R*)-4-(2,2-Dimethoxyethyl)-3[(1S*)-1-hydroxyethyl]azetidin-2-one (7), which has been stereoselectively synthesised via the 4-methoxycarbonylisoxazoline (4), was converted into (±)-epithienamycins A (2) and B (3)[(±)-olivanic acids MM22380 and MM22382], (±)-deacetylepithienamycin A (20), and the 2-phenylthio-substituted compound (19). This total synthesis confirms the relative stereochemistry of the natural antibiotics.


Ecosystem services, the benefits humans derive from nature, represents a radical departure in our perception of linked environmental and social problems and the actions we need to undertake to address those urgent challenges. Due to its increasingly widespread policy prominence, understanding and appraising its conceptual and practical benefits whilst at the same time acknowledging its potential pitfalls represents an important endeavour. Comprising seven parts and sixteen chapters, the first five parts of the thesis outline the main environmental and social challenges we face, presenting the core foundations, contemporary debates and developments in ecosystem services scholarship, whilst also underlining its increasing coalescence with sustainability discourse. In Part 6 we focus on a key application of ecosystem services with respect to its translation into incentive-based environmental management schemes, namely: payment for ecosystem service programmes and agri-environment schemes. We present a systematic global analysis of payment for ecosystem services programmes, highlighting the successes and challenges they face, whilst also providing an approach to improve their design and evaluation as a route to maximise their effectiveness. Turning our attention to a globally significant ecosystem, the thesis assesses the prospects for jointly developing seagrass Blue Carbon initiatives and payment for ecosystem service schemes, arguing that complementing these activities would produce significant climate, conservation and livelihood benefits. Switching contexts, from focusing on incentive schemes primarily in operation in developing countries to those designed to balance productivity and conservation matters in the agricultural sector of developed countries – the thesis explores the stakeholder and institutional factors affecting agri-environment scheme operation and implementation through the eyes of key operatives. Finally, in Part 7, I argue that a landscape framing and approach to ecosystem services provides an effective route to improve environmental management decision-making and policy as well as comprehensively addressing the linkages between ecosystem services and human-wellbeing.


Rapidly-expanding urban populations with increased refuse per capita have placed great strains on available disposal facilities. Thus, the economic feasibility of composting municipal refuse was explored on the basis of data collected from fourteen composting plants in Europe and Israel. These plants used either the Dano Biostabilizer the Dorr-Oliver Rasp, the ventilated cell, the Buhler-Dano combination, or the Van Maanen process. None of the plants visited was able to cover its capital service costs and operating expenses through income obtained from salvage and sale of compost. Deficits ranged from $0.32 to $5.32, with an average net cost of $3.38 per ton of refuse processed. Substantial prices for compost were obtainable practically only in Israel. The economic considerations derived from these data were applied to conditions in the United States, where, based on comparative cost indices, construction and operating costs would be considerably higher. Hence, it is most important that a determination be made that a continuing demand for compost exists before a compost plant is constructed.

Abstract In this note, structural decomposition of linear periodic continuous-time systems is discussed. A fundamental problem to decompose a state of a periodic system into controllable and uncontrollable parts is conjectured to be achieved by a continuously differentiable and periodic coordinate transformation with the same period of the system, however there is a counterexample to this conjecture. Hence we derive a condition for the existence of such a coordinate transformation. We also prove that, by relaxing a class of coordinate transformation, it is always possible to construct a periodic coordinate transformation with the double period of the periodic system.


Learning analytics is defined as the measurement, collection, analysis and reporting of data about learners in order to optimize their learning. It was recognized very early that the field of learning analytics offers promising possibilities for education and assessment. In this paper, the interactive and personalized e-assessment system askMe! is presented that makes use of learning analytics in order to turn learners into effective and better learners. The paper also shows how the system addresses future challenges in the field of learning analytics. Finally, a brief summary of the use and evaluation of the system in a real-life setting completes the paper.


This article continues a discussion begun in Part One. Together they re-examine the central thesis of Professor John Hull's (1975) book, School Worship, An Obituary, that the practice of worship in school is inappropriate. He attempted to establish his thesis through the analysis of the concept of education and of the concept of worship, and thus to show their essential incompatibility. Part One reviewed what an incompatibility might mean in the school context. After all, many diverse activities are pursued during the school day that, practically speaking, could not be done simultaneously in the same room. His thesis must be taken in the stronger form that, theoretically, the sense of education and the sense of worship are such that the two activities together are conceptually incoherent. The earlier article also reviewed his analysis of the concept of education. It questioned his definition and showed that it hinged on some of the dubious assumptions of an evidentialist philosophy. A better view of understanding and pedagogy might actually require the practise of worship in school. If it is the intention of our society to communicate the substance of religious life to the young, training them in worship may be the best, if not the only, way to do this. The features of education that Hull has identified have been selected for their rhetorical force. They appear to challenge what are assumed to be essential features of worship. Whether they do so in fact will depend on one's understanding of worship, but in what follows, his key assumptions about worship are put to the test and found wanting. Part Two, therefore, investigates Hull's understanding of worship. It finds that he believes a prior unconditional commitment to the belief 'God exists' is of the essence of worship. For him, it is this commitment that puts it at odds with education which he believes must scrutinise everything. The arguments against Hull here are designed to show that he is mistaken in his understanding of worship. Practices do not develop on the formation of belief systems first. Furthermore, religiously speaking, worship actually embraces a radical questioning. Finally, his assumption that there is a logical incompatibility in having an unconditional commitment and in embracing the practice of radical questioning is tested against the figure of Socrates. In the life of Socrates one can see how piety and educational practice belong together in such a way that one is the expression of the other. It is concluded that the nature of education and worship are at stake. These may have changed in such a way that they can no longer be pursued together. But there was a time when education flowered into worship, and worship found its substance in education. Hull's case concerning their intrinsic conceptual incoherence through philosophical analysis does not succeed. He has only shown us how our world has changed, and that, not necessarily for the better.
