This research is relative to the copper alloy with elements of Cr and Zr which may effect the flexibility and electric conductivity, expect to provide some new ideas as rolling for making to produce the high accuracy, high strength, high conduct electricity in industry produces. In this research the vacuum furnace, casting Cu- Cr- Zr alloy in iron mold at atmosphere were used, the result shows: adding alloy elements not only can raise the strength of alloy but also have very good flexibility for hot rolling. We fine that: solid solution treatment can greatly decrease the effect of electric conductivity by alloy elements. As a result shows: the ingots which have been solid solution treated have higher conduct electricity than those not been treated.


We, for the first time, fabricated an additive-free battery electrode composed of Fe-zeolitic imidazolate frameworks-derived Fe2O3 nanoparticles (NPs) incorporated in carbon shells (Fe2O3@C) through electrophoretic deposition (EPD). High specific capacity of Fe2O3@C without additives comparable to that of the theoretical capacity (1007mAh/g) suggests that the electrochemical conversion reactions accompanied by lithiation and delithiation process are not significantly limited by the absence of the conductive agents and binders. The additive-free system paves the way for an efficient experimental probe to investigate the intrinsic electrochemical properties of the metalorganic framework-derived nanostructures. © The Author(s) 2020.

The distribution of moment magnitudes for a hydraulic fracture treatment is related to the complexity of the fracture network through the slope of the frequency-magnitude distribution, known as the b-value. Characterizing this complexity relates to effective field drainage and can be used to calibrate predictions of fracture-mechanical models. As the b-value is determined from the magnitude distribution, then it may be glimpsed by using only a single-well observation array. We use the example of a multi-well observation array to validate this observation. The b-value field for the treatment zone is determined and compared against the distribution of microseismic moment tensors to validate that the complexity inferred by the b-value is reflected in the distribution of mechanisms determined by inverting for the moment tensors.


WLANs (Wireless Local Area Networks) are widely used for Internet access. But the WLANs in locations such as airports and large conventions usually suffer poor performance in terms of downlink TCP (Transmission Control Protocol) throughput To alleviate these problems, we propose an AFCP (Adaptive Flow Control Proxy) approach, which acts like a TCP Proxy and monitors the traffic flowing through the AP. Using NS-3 simulations, we demonstrate that AFCP can improve the downlink TCP performance, provide good uplink/downlink fairness and promote the total throughput of WLAN.


This work concerns the first spectroscopic measurements of energetic charged particles on Omega. Individual line profiles include D-3He protons (14.7 MeV) and alphas (3.6 MeV), D-T alphas (3.5 MeV), D-D protons (3.0 MeV), and D-D tutons (1.0 MeV)


Aerodynamic levitation is an effective way to suspend samples which can be heated with CO2 lasers. The advantages of this containerless technique are the simplicity and compactness of the de- vice, making it possible to integrate it easily in different kinds of exper- iments. In addition, all types of materials can be used, including metals and oxides. The integration of aerodynamic levitation at synchrotron and neutron sources provides powerful tools to study the structure and dynamics of molten materials. We present here an overview of the existing techniques and of the developments made at the CEMHTI in Orleans, as well as a few examples of experimental results already obtained.


The UK government should take a "zero tolerance" approach to covid-19 to prevent thousands more deaths, a group of experts from across England, Scotland, Wales and Ireland have warned.1

The panel, which included members from the Independent Scientific Advisory Group for Emergencies (iSAGE), the former health secretary for England, Jeremy Hunt, and advisers from across the nations, met to discuss a covid-19 elimination strategy. They raised concerns over the number of covid-19 deaths occurring in England and the government's lack of a policy to reduce deaths.2

The call came after England's chief medical officer, Chris Whitty, said at the final Downing Street covid press conference on 23 June, "I would be surprised and delighted if we weren't in this current situation through the winter and into next spring."

Given that currently more than 100 people are dying each day, iSAGE estimated that this would mean around 27 000 deaths in England by March 2021, even without a second wave. "It is the view of Independent SAGE that a death toll from covid-19 of this magnitude is not only preventable but is absolutely …


While it invites deep and sustained attention, Michael Ondaatje's Handwriting has seldom been studied, since its publication in 1998, for the author's concern with peace, even though this collection of poems highlights peace and war. I will argue that in Handwriting, Ondaatje proposes ways to achieve internal and external peace that are not only relevant to the Sri Lankan civil war but also to the wider contemporary world. In Handwriting, Ondaatje presents a narrator who returns to Sri Lanka because of a sense of dislocation, and who writes to understand the cause of ethnic violence and reconstruct the Sri Lankan past that was lost during the civil war. In doing this, Ondaatje shows a possibility of peace for Sri Lanka and his readers. People in conflict can be united when they are less obsessed with their different identities, recognize their shared desire for peace, respect one another's differences, and work together to create a shared memory that does not homogenize and is open to new elements from other cultures. As the narrator investigates this situation by writing creatively about Sri Lankan people, his example also demonstrates a way to achieve mutual understanding by artistically constructing a shared memory. Alain Badiou's views about events constitute the major theoretical framework of the present study.


Chronic renal failure runs a relentlessly progressive course, with occlusive glomerulosclerosis and an inexorable decline in glomerular filtration rate (GFR) to end-stage renal failure. I The rate of progression varies from patient to patient, but a common factor underlying this progression is glomerular hyperperfusion and hyperfiltration in remnant nephrons as a response to loss of functional renal mass.' A usual concomitant is an elevation in the urinary excretion of proteins, principally albumin.' These abnormalities can be modulated by a number of factors. In chronic renal failure, for instance, a reduction of dietary protein results in a lessening of the glomerular haemodynamic abnormalities and a slowing of the rate of decline of GFR, as well as a fall in urinary protein excretion. '-I Diabetes mellitus results in progressive glomerulosclerosis and renal failure in up to 40% of patients with insulin-dependent diabetes mellitus (IDDM) and is no exception to the above gener~lities.~ However, it is unique in that in the early stages, before any clinically apparent signs of renal disease, both albumin excretion rate (AER) and GFR may be elevated even in the absence of any reduction in total nephron n~mber . " ,~ Indeed both these abnormalities, called microalbuminuria and hyperfiltration, have been shown to predict later clinically overt diabetic nephropathy, marked by persistent proteinuria detectable by standard clinical tests (e.g. Albustix test).',"


Context. The Large Magellanic Cloud (LMC) is rich in supernova remnants (SNRs), which can be investigated in detail with radio, optical, and X-ray observations. SNR J0453–6829 is an X-ray and radio-bright remnant in the LMC, within which previous studies revealed the presence of a pulsar wind nebula (PWN), making it one of the most interesting SNRs in the Local Group of galaxies. Aims. We study the emission of SNR J0453–6829 to improve our understanding of its morphology, spectrum, and thus the emission mechanisms in the shell and the PWN of the remnant. Methods. We obtained new radio data with the Australia Telescope Compact Array and analysed archival XMM-Newton observations of SNR J0453–6829. We studied the morphology of SNR J0453–6829 from radio, optical, and X-ray images and investigated the energy spectra in the different parts of the remnant. Results. Our radio results confirm that this LMC SNR hosts a typical PWN. The prominent central core of the PWN exhibits a radio spectral index αCore of −0.04 ± 0.04, while in the rest of the SNR shell the spectral slope is somewhat steeper with αShell = −0.43 ± 0.01. We detect regions with a mean polarisation of P (12 ± 4)% at 6 cm and (9 ± 2)% at 3 cm. The full remnant is of roughly circular shape with dimensions of (31 ± 1) pc × (29 ± 1) pc. The spectral analysis of the XMM-Newton EPIC and RGS spectra allowed us to derive physical parameters for the SNR. Somewhat depending on the spectral model, we obtain for the remnant a shock temperature of around 0.2 keV and estimate the dynamical age to 12 000–15 000 years. Using a Sedov model we further derive an electron density in the X-ray emitting material of 1.56 cm −3 , typical for LMC remnants, a large swept-up mass of 830 M� ,a nd an explosion energy of 7.6 × 10 50 erg. These parameters indicate a well evolved SNR with an X-ray spectrum dominated by emission


Simultaneous measurement for strain and temperature is the key and difficult point.This paper firstly introduces the physical mechanism of producing cross sensitivity,then presents the solution viewing from the dual wavelength matrix method,and the double-parameter matrix method and temperature (strain) compensation method,while analyzing the meth-ods,so that we can choose an optimal solution according to application.


The overall incidence of RFM in dairy bovines of Amul milk shed area of Anand district during the year 2010–11 was found to be 46.37 per cent of the total reproductive disorders (27480/59267) and as 4.81 per cent of the total clinical cases (27480/571080) attended. The highest incidence was observed during monsoon (45.52%) followed by winter (32.66%) and the least in summer (21.82%). Further, an epidemiological investigation was carried out on 50 Surti buffaloes with RFM managed at the farmers' door revealed that the sex of calf and suckling/weaning had no effect on the incidence of RFM. The maximum number of RFM cases were observed in buffaloes of third parity (32%) followed by second (20%) and fourth (16%) parity. With the increase in the quantity of concentrate feeding, the incidence of RFM decreased. The effect of previous parturient abnormalities showed less effect on RFM in buffaloes. However, as the birth weight of calf increased, the incidence of RFM increased.


This study examines the effect of dual role advisors in acquisitions on shareholder value creation for both the acquirer and target. Dual role advisors are advisors that provide both advisory services to either the acquirer or target and are involved in underwriting or syndicating securities issued to finance the deal. Previous studies find that being a dual role advisor can create a conflict of interest in which the investment bank's advice to either the acquirer or target is impacted by the bank's desire to obtain financing fees from financing the transaction. Our study contributes to the existing literature by studying the effect of both acquirer and target advisors in dual roles on shareholder value creation and by analyzing how the amount of proceeds of the deal-related security issue(s) impacts this relationship. Using a sample of 263 acquisitions involving U.S. non-financial firms in the period between January 1, 2000 and December 31, 2014, this study provides only partial support for the fear that dual role advisors provide biased advice in order to secure themselves of obtaining lucrative financing fees. More specifically, it is shown that deals with an acquirer advisor in a dual role are completed at significantly higher premiums. However, this study does not find that this association increases in magnitude with an increase in the total amount of proceeds of the deal-related security issue(s) and it also does not find a significant association between dual role advice for the acquirer and acquirer announcement returns. Furthermore, after controlling for the proven endogenous nature of target advisors in dual roles, this study does not find evidence for an influence of target advisors in dual roles on either deal premiums or acquirer announcement returns, even in deals with sizeable security issues. As such, this research concludes by stating that the conflict of interest only exists for acquirer advisors in dual roles while with target advisors in dual roles no conflict of interest exists.


Family involvement is recognised as an important part of the rehabilitation process for individuals suffering from brain injuries. However, in an attempt to prevent the spread of COVID-19, healthcare institutions were obligated to implement visitor restrictions. The aim of this study was to understand the experiences of family members with respect to communication based on video calls with their close relatives who were suffering from brain injuries and undergoing inpatient rehabilitation during the pandemic. We included a purposive sample of 11 participants/family members who communicated consistently with their loved ones via video conferencing as part of the occupational therapy intervention. Qualitative data was collected using a semi-structured interview. Two independent researchers performed a thematic analysis based on the data inquiry method and highlighted three main themes: (1) coping with a traumatic brain injury of a family member, (2) video conferencing experiences with a family member during rehabilitation, and (3) family resilience factors. Our study highlighted that there were changes in the daily lives of the family, as well as that family members had a strong emotional response due to the traumatic event and the inability to stay with the affected individuals in the hospital. Interactions via video conferencing proved to be significant for the participants since it provided them with an insight into the health condition of their family members, enabled their involvement in the rehabilitation process, and allowed them to monitor the recovery process. The above-mentioned factors also contributed to the resilience of participants. Our findings indicate the benefits of virtual communication and involving family members in the rehabilitation process, especially in situations where hospital visitation is impossible. © 2022, University of Zagreb, Faculty of Mining, Geology and Petroleum Engineering.

The plan is based on the final report of the AAU Task Force on Acquisition and Distribution of Foreign Language and Area Studies Materials that was issued in April 1994 and that was endorsed by the AAU Presidents and the ARL Directors at their respective membership meetings in spring 1994. The Task Force recommended the creation of a "network-based, distributed program for development of foreign acquisitions for U.S. and Canadian research libraries." The Task Force further proposed the implementation of the program with three demonstration projects targeted on research materials that originate in Latin America, Germany, and Japan.


Objectives: Quality of sexual life can be influenced by cultural and social contexts. This study aimed to investigate the relationship between structural determinants of health (such as education, income level, job, culture, and ethnicity) and quality of sexual life in women. Methods: In this systematic review, we searched six databases, including Web of Science, Scopus, ProQuest, PubMed/Medline (NLM), Cochrane, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) to obtain all the related observational studies (cross-sectional, cohort, and case-control). Results: Nine studies met the inclusion criteria. Based on the Newcastle-Ottawa Scale (NOS), the risk of bias in most of the included studies was fair. According to the results, the relationship between education level and quality of sexual life among women was significant in four studies. Also, in one study, job and income level were significantly correlated with women's quality of sexual life. Conclusions: Based on the results, structural determinants of health, including education, job, and income level were significantly related with women's quality of sexual life.


IT IS a tribute to the good judgment of the editors of the Library Quarterly as well as to Mr. Archibald MacLeish that the annual reports of the Librarian of Congress, having become really significant documents in the field of librarianship, have been recognized as proper subjects for careful review. While it is regrettable that the review of the 1942 Report was delayed because of this reviewer's commitments in the war effort, the circumstance may have been a fortunate one in that there is a continuity in these reports which invites study of a series rather than of single editions. The first review' of this series indicated the early stages of that continuity in the report years I939, 1940, and


With the rapid development of Chinese economy, Chinese firms are eager to grow bigger and stronger. An increasing number of companies are utilizing diversification strategy in order to achieve these objectives in short time. However, recent studies have shown that diversification cost has exceeded the total benefit. Those studies labeled it as diversification discount phenomenon. Many theories, such as resource-based theory, transaction cost theory, and agency theory, have been used to explain corporate decision for adopting diversification strategy. Although these studies found that diversification strategy is a rationale decision, they ignored the impact of the irrational activity(e.g. manager's overconfidence and ignorance of initial motivation of managers) of managers on corporate diversification strategies. Lee and Yates'(1995) cross-cultural study finds that Chinese are more confident than Americans. This study adopts the perspective of behavior finance and free cash flow theory, and relaxes previous hypothesis that most managers are rationale.The sample of the listed companies of Shanghai and Shenzhen between 2007 and 2010 in China was used to examine the effect of managerial overconfidence on the diversification of the listed companies, shed new insights into enterprise diversification strategy, and expand corporate diversified motivation theory. We also investigated the impact of free cash flow on enterprise diversification, and further tested the impact of the interaction between managerial overconfidence and free cash flow on enterprise diversification. The results show that: First, there is a significantly positive relationship between managerial overconfidence and the level of enterprise diversification. For enterprises in emerging economies, managers are more likely to be overconfident due to Chinese traditional culture. There is one overconfident manager out of three managers in our sample. Hence, the empirical results show that overconfident managers tend to underestimate the risk of diversification and overestimate the return and their control abilities. As a result, they adopt the diversification decision to satisfy the desire to make firms become larger and stronger. This finding is consistent with the conclusion of Jiang's study that overconfident managers will use internal investment and external acquisition to expand firms and improve diversification level. Second, the more the free cash flow the higher the level of enterprise diversification. Under the inadequate regulation environment combined with imperfect manager market in China, the lack of restrictions on managers can lead to the expansion of manager control. When firms have abundant free cash flow, manager will use it to implement diversification strategy without paying dividends to shareholders. Third, in firms with abundant free cash flow the level of diversification in firms with overconfident managers is higher than firms with non-overconfident managers. In firms with abundant free cash flow, managers are more likely to feel that they have control and tend to overestimate the return of diversification and underestimate the risk and cost. Therefore, managers' idea to implement diversification is improved by the abundant free cash flow. As a result, managers will participate in more diversified business using the excess fund.


Objective To observe the changes in hypersplenism after orthotopic liver transplantation(OLT) and investigate the effect of OLT on hypersplenism. Methods Based on the clinical data of 14 eligible OLT patients operated on in our hospital during two and a half years, an analysis of the pre operative values of the thickness of the spleen, blood WBC and PLT count was made,and the postoperative pattern of changes of portal flow velocity was observed. Results Blood WBC and PLT count returned to normal 1 month after the operation, and the thickness of spleen reduced about 17.0% in the first month , but had no additional change at 1 year later. Portal flow velocity increased significantly 1 month after operation , then decreased slowly in the first year. Portal flow velocity , blood WBC and PLT count were all significantly related to the thickness of the spleen. Conclusions The high velocity of portal flow after OLT was mostly attributed to increased flow from the splenic vein; the main cause of the decrease in the level of blood WBC and PLT in hypersplenism before operation is augmentation of splenic volume; the recuperation of hypersplenism after OLT relies on the extent of reversion of splenic volume. It is not necessary to perform splenectomy in patients with hypersplenism when they receive OLT.


Climate catastrophe insurance has been introduced and run by the government since 2008 in response to try to adapt to climate change. Within this insurance system, however, only houses and green houses are covered, and other buildings and structures are excluded. These days the government has enlarged the limit of application to trade people, most of whom are the livelihood of the low-income bracket and the small-scale self-employed people vulnerable to the climate change, yet this system still lacks its inducement to insure them. In addition, to give them a virtual support from the system, the improvement of the insurance system should be imperative. To make this insurance system effective, accordingly, the reform and development of the policies must take precedence. First of all, insurance products should be subdivided to offer them practical assistance, especially considering those who get damages from disasters are lessees. Secondly, limit of liability should be classified into several groups for trade people to set their limit for themselves. Thirdly, data concerning climate disasters need to be cumulated from the various damages of various buildings. Lastly, construction of public service system on education and for the climate catastrophe insurance contracts should be stronger than now.

The positive active mass of a pasted‐type lead‐acid cell changes morphologically to a great extent during deep discharge‐charge cycles. In order to reduce these changes, the effect of compression on the active mass has been studied. When compression is applied to a positive plate, expansion of the positive active mass is suppressed and the structural changes become smaller. Therefore, the cycle life of the positive plate increases remarkably. The reason why the cycle life increases by compression is due to suppression of the decrease in cohesion between particles.


Melasma (facial dermatoses) is an acquired chronic disorder of hyperpigmentation over sun exposed parts and continues to be a therapeutic challenge due to the presence of melanin at varying depths in the epidermis and dermis, and many researchers are working hard to find a solution. The main culprit to remain is direct sun exposure, with other factors like drugs, genetic predisposition, thyroid abnormalities, pregnancy, phototoxic and photoallergic cosmetics. Melasma continues to have a remarkable impact on the well‐being of affected patients causing deep psychological and social anguish, and with the expansion of cosmetic dermatology globally, treatments that are successful against skin diseases and boost beauty without prolonged recovery periods, or exposing patients to the risks of surgery, are increasingly recognised and acknowledged. Many clinicians have used various peeling in facial acne, scarring, and hyperpigmentations, and there have been no well‐controlled studies comparing them with other conventional agents. Case presentation: a unique case of facial hyperpigmentation in a black female who presented seeking help which can be attributed to increased aesthetic awareness among people nowadays. A single session of black peel several passes was performed and the lady noted a lightening effect in the following weeks.


To investigate intrachromosomal variations among allied species we compared chromosomal banding patterns in 3 species of rats, Rattus norvegicus (1a, WKA strain), R. rattus (1~, captured in Sapporo) and R. exulans (1 ~, 1d, kindly supplied by Dr. T. H. Yosida, National Institute of Genetics, to whom we express our cordial thanks). Airdried chromosome slides prepared from adult bone marrow cells and/or cultured fibroblasts were subjected to the banding pattern analysis following the Q(Mori and Sasaki 1973), G(Seabright 1972 or Summer et al. 1972), and C-staining (Summer 1972) methods. The 3 species showed the same diploid number, 42. The Qand Gband analyses revealed a general similarity of their karyotypes, with some exceptions as described in the following. Representative Q-band karyotypes were shown in Figure, which were compared according to the numbering system proposed by the committee for a standard karyotype of R, norvegicus, (1973). The karyotype of R. exulans was nearly identical to that of R. norvegicus, except for an excess bright band in the proximal region of the no. 1 long arm, the absence of satellites in no. 3 and the Y chromosome which was as large as no. 8 autosomes. Since the Y chromosome of this species has been reported to be a smaller element (Yong 1969: Yosida 1973), the unusually long Y in the presen c specimen might be an intraspecific variant. The karyotype of R, rattus displayed considerable deviations from that of R, norvegicus (Figs. 1 and 2), though the former species has been known to show several types of chromosomal polymorphism in natural populations (Yosida and Sagai 1972). Nos. 1, 12 and 13 autosomes of the present specimen were apparently acrocentric, while the corresponding pairs in R. norvegicus were subtelocentrics having different banding patterns. Nos. 14, 15 and 16 autosomes also exhibited different banding patterns between the two species. The differences in nos. 1, 13 and 15 could be explained by pericentric inversions, but those seen in the other elements were inexplicable by such a simple mechanism. The Y chromosome of R. rattus was very small, showing a distal faint band. The G-band karyotypes of the 3 species were essentially similar to the Q-band ones, though the centromeric regions and satellites were more clearly demarcated in the former. Thus, we confirmed the G-band studies by Yosida and Sagai (1972, 1973), with more precise demonstration of inteaspecific variations in smaller chromosomes. The

: Burnout is a work-related mental and physical syndrome resulting from long-term exposure to emotional and interpersonal stressors. The health of Medical Laboratory Professionals may be affected by prolonged exposure to massive stress, despite widely prevalent burnout but a few studies about the specific patterns of burnout in this profession. Purpose: This study aimed to assess the magnitude of burnout and its associated factors among Medical Laboratory Professionals in public hospitals of Jimma zone, southwest Ethiopia, from May 1 - June 1, 2022. Patients and methods: An institutional-based cross-sectional study was conducted, on 153 study participants. Data collection was done using a pretested self-administered questionnaire. Data were verified, encoded, entered with EPI INFO Version 7, and analyzed using SPSS Version 21.0. Descriptive statistics were analyzed through cross-tabulation. Further, bivariate and multivariable logistic regression analysis were computed to identify predictor variables significantly associated with the outcome variable. All variables with p-value ≤ 0.25 in bivariate analysis were entered into the multivariable logistic regressio n model to adjust possible confounders. Finally, variables with a p-value of <0.05 in the final analysis, were considered to explain the presence of association.

We examined the impact of acoustic injury on the cochlea by assessing auditory brain-stem response (ABR) threshold shifts, outer hair cells, and the number of synaptic ribbons before and after noise exposure. The ABR threshold was elevated immediately after noise exposure, but recovered over time; 14 days after noise exposure, the ABR threshold was approximately 15 dB higher than before exposure. There were few damaged outer hair cells. The number of synapses directly under inner hair cells markedly decreased immediately after noise exposure, but then exhibited early signs of recovery. Twenty-four hours after noise exposure, the number of synapses was higher than before exposure. Subsequently, synapse number decreased. Seven days after noise exposure, synapes number was lower than before exposure. In this acoustic injury model, although the synapses were damaged, as described in the previous reports on the temporary threshold shift (TTS), the regeneration of synapses was promoted soon thereafter. There appears to be a point during the repair process when the number of synapses temporarily increases. This model is considered to be a partially reversible synaptic damage model. This study revealed an association between the intensity of noise exposure and the severity of functional and histological damage.


In Brazil, corrugated tiles are the most used to cover large spans, since they are considered lightweight tiles that are easy to handle and have larger dimensions compared to conventional tiles. Currently the ecological tile is recognized as a new option of construction market. The objective of this term paper is to show a comparative research on the efficiency of ecological corrugated tiles and fiber cement through a bibliographical study about the tests of simple bending rupture loading and economic viability.
In order to realize this study, we used data obtained through the manufacturers through a budget of each tile studied. Through a bibliographical research, it was possible to realize a comparative study between these tiles, and it was possible to emphasize that the ecological tiles have a simple flexural strength, being considered three times bigger than the asbestos cement tiles. In the budget with the obtained data, the asbestos cement tile has a value of 6,98% smaller than the ecological tiles. The companies manufacturing corrugated fiber cement tiles are the leaders on the market´s world moving billions of reals on the construction. The bending load of the ecological tiles is approximately three times as high as the asbestos cement tile, therefore, the ecological tiles have a better performance and a durability, however the cost of the ecological tile is higher, compared to the fiber cement tile.


The time series temperature data of winter and the whole year for over 80 years from 1915 to 2000 in Huhhot are analyzed by using the wavelet transform.From analyzing the over 80 years data,the conclusions that temperature changes of some region or area exist certain regularity,such as periodicity and mutability can be drawn.Not only the temperature state at the different time scales but also the periodicity and the mutability of temperature changes in Huhhot are analyzed.From the analysis,7 years and 2~3 years periods are found in winter time series,and 13 years,5 years periods are found in the whole years time series.Additionally,the time that the temperature appeared to change is also showed and the temperature change tendency in the future is forecast from a large scale.


This paper examines Byzantine fool saints, aiming to verify that the association of these ascetics with demons could be traced back to the first representative of this typology of saints, Symeon of Emesa. Through the study of the Life of Symeon the Fool, by Leontius of Neapolis, Symeon's actions will be analyzed, trying to identify similarities with various characters linked with demons in Christian moral in order to point out the demoniacal characteristics of Symeon's behavior.


A previously unrecognized phytoalexin has been isolated from soybean cotyledons that had been infected with bacteria or exposed to ultraviolet light. The phytoalexin has been purified to homogeneity by silica gel flash chromatography and high pressure liquid chromatography. It has been structurally characterized by its ultraviolet, circular dichroism and nuclear magnetic resonance spectra, polarimetry, and its mass spectrometric fragmentation pattern. The phytoalexin, (6aS,llaS)-3,6a,9-trihydroxypterocarpan, is a compound that had previously been detected in CuCI2-treated soybeans and is structurally related to the previously identified soybean phytoalexins glycerollins I to IV. It is proposed that the trivial name glycinol be used for this phytoalexin. Glycinol is a broad spectrum antibiotic capable of prolonging the lag phase of growth of all six bacteria examined, namely Erwinia carotovora, Pseudomonas glycinea (races 1 and 3), Escherichia coli, Xanthomonasphaseoli, and Bacillus subtilis. Glycinol also inhibits the growth of the fungi Phytophthora megasperma f. sp. glycinea (race 1), Saccharomyces cerevisiae, and Cladosporium cucwmerinum. Glycinol is a static agent against the six bacterial species listed above and against S. cerevisiae, and appears to be static against the other fungi examined. As with other phytoalexins, there is no correlation between the pathogenicity of a microorganism and its sensitivity to glycinol. Phytoalexins are low mol wt antimicrobial compounds produced by plants in response to challenge by microorganisms. These compounds accumulate at the site of infection and are involved in the plant's defense response to potential pathogens (3, 8, 14). The accumulation of the pterocarpan phytoalexins, glyceollin4 (Fig. 1), by soybean (Glycine max) in response to fungal attack has been well documented (12). In vitro studies have shown glyceollin to be inhibitory to the growth of both bacteria and fungi (1, 11, 12). The major antibacterial compound accumulated when soybean cotyledons are challenged by the bacterium Erwinia carotovora is not glyceollin. We have purified the major antibacterial compound and have identified it as (6aS, 1 laS)-3,6a,9-trihydroxypterocarpan, ' Supported by the Department of Energy (Contract --EY-76-S-021426) and The Rockefeller Foundation (RF 78035). 2 Current address: University of Wisconsin-Madison, Department of Plant Pathology, 1630 Linden Drive, Madison, WI 53706. 3To whom correspondence should be addressed. 4Abbreviations: glyceollin, glyceollins I to III (Fig. 1) migrate as a single spot on TLC and are collectively referred to as glyceollin throughout this paper; TSB, trypticase soy broth; EMM, Erwinia-defmed medium; HPLC, high pressure liquid chromatography; CFU, colony-forming unit. for which we propose the trivial name glycinol. This pterocarpan has been previously observed as a quantitatively minor constituent in CuCl2-treated soybean cotyledons, although no antifungal activity was recognized to be associated with it (18). The present study describes an improved isolation procedure for the pterocarpan leading to mg quantities of the crystalline compound. We present also the results of our studies of the effect of glycinol on growth of a variety of microorganisms. MATERIALS AND METHODS Plant Material. Certified quality soybean seed (Glycine max [L.] Merr. cv. Wayne) was obtained from Wilkens Seed Co. Pontiac, IL. The seed was stored in closed containers at 4 C and hand sorted for soundness before planting. The sorted seeds were planted at a density of about 75 g seed/tray (40 x 30 x 9 cm) on a 2-cm layer of potting soil (Bacto Potting Medium, Michigan Peat Co., Houston, TX) overlaying a water-soaked 4-cm layer of vermiculite (W. R. Grace and Co., Cambridge, MA). The seed was then overlayed with a 2 cm layer of vermiculite, and watered with 400 ml deionized H20/tray. The seedlings were grown in a Percival model PGW-108 growth chamber with a regime of 14 h of illumination (4,300 lux) at 24 C and 10 h of darkness at 18 C. The RH was maintained at about 75%. Each tray was watered with 200 ml deionized H20 the 2 days following planting, and 400 ml thereafter. Microorganisms. E. carotovora (Jones) Holl. (ATCC 495) and Xanthomonas phaseoli subsp. sojensis (ATCC 17915) were obtained from the Americian Type Culture Collection and were maintained on TSB (Baltimore Biological Labs) agar slants and plates. Wild type Bacillus subtilis (Ehren.) Cohn FIl was obtained from A. Kaji, Department of Agricultural Chemistry, Kagawa University, Kagawa, Japan, and maintained on TSB. Escherichia coli (Migula) Cast. and Chalm. KIO, obtained from R. R.

The deficiencies related to the school performance of the children of the Educational Unit of Ecuador, reveals that the methodological strategies used do not have the expected effect. This was fully detected in the light of pre-professional practice, and certainly now as a teacher of this Educational Institution.

In our research work, we carry out the problematization of the scientific fact, contrast it with information from previous works, and draw the first preliminary conclusions. So that taking into account these previous considerations, it appears after the problematization, the foundation with the respective theoretical sustenance, and next to that, the description of objectives, which are the ones that guide the course of the researched.

To this we add the methodological structure, and the detail of the Proposal, based on the theoretical-methodological principles of Project-Based Learning, which is considered as an alternative to a valid solution, in view of the significant problem of the deficiencies evidenced with regard to the school performance. Our investigative work consists of 4 Chapters: Chapter 1, The Problem; Chapter 2 The Theoretical Framework; Chapter 3 Results of the investigation, and Chapter 4 The Proposal.


Taguchi's L9 static design was employed to determine the robust design of a zinc oxide (ZnO) nanofilm surface plasmon resonance (SPR) bimetallic sensor. The control factors such as incident wavelength and different thicknesses of silver, gold and ZnO layers were selected. Noise factors include thickness of the chromium layer and the diameter of the biomolecules (i.e. urea) which were simulated using Finite-Difference-Time-Domain (FDTD). Results obtained show that the thickness of the gold layer has a 41.32% dominant factor effect on the minimum reflectance of light $(\mathbf{R}_{\mathbf{min}})$, whereas the incident wavelength has a 73.15% dominant factor effect on the full-width-at-half-maximum (FWHM) of the SPR signal. The confirmation tests carried out show that the values of $\mathbf{R}_{\mathbf{min}}$ and FWHM were optimized using Taguchi's orthogonal array method leading to a robust design of the SPR sensor.

Abstract Prediction of springback during press forming has become more important due to the recent trend of application of high strength steels in automotive white body parts. The accuracy of springback prediction depends on the estimation of recovery strain after die release. As it is well known that unloading behavior after pre-strain shows a nonlinear stress-strain relationship, a material model which considers nonlinear elastoplastic behavior is necessary for accurate springback prediction. In this study, the nonlinear behaviors of high strength steel sheets under uniaxial and biaxial stress states were measured. A new material model that considers nonlinear behavior was proposed and implemented in finite element method (FEM) software. Press-forming tests of curved hat-shaped parts and the corresponding springback analyses were performed, and the springback angles were evaluated. The springback predictions made using the proposed model showed good agreement with the experimental results.


A hybrid operation network model is proposed to describe and evaluate a missile defense system. More specifically, the network model provides a formal modeling approach based on the concept of the Combat Network Model. It represents uncertain information of the combat space with probabilities and the causal strengths (CAST) logic. Besides, the degenerate value of CAST parameter is discussed, and a complete conflict situation is discovered which the existing CAST algorithm cannot handle it. Furthermore, a novel modeling framework is proposed with the degenerate CAST parameters and virtual actionable nodes. The framework characterizes the missile defense process considering such factors as time delay, location, capability, and operation scope of weapons. The feasibility of the proposed model is demonstrated using a simulated example along with a sensitivity analysis. The results show the advantage of the joint control and command, identify the sensitive events/activities regarding the efficiency improvement, and suggest an optimal expected operation time window.


The Human Fertilisation and Embryology Act 1990 represents a milestone in biomedical regulation. Not only does it finally bring to fruition the long running government discussions about the proper limits of reproductive science, it also provides the first attempt in English law to provide a comprehensive framework for making medical science democratically accountable. Its interest therefore arises both from the solutions it adopts for particular issues and from the model of regulation on which it builds. If the licensing authority which lies at the heart of its provisions proves successful, it is likely to be replicated in the oversight of many controversial areas of medical progress. ' The 1990 Act is also signiElcant as a model for establishing a workable compromise between incompatible ethical positions. The issues underlying the provisions of the Act are not ones on which a consensus exists within our society. This resulted in an unusual Palliamentary history.2 The Bill was introduced into the House of Lords as a Government Bill but was mostly unwhipped and it contained alternative versions of the cl ucial clause dealing with the permissibility or otherwise of research on human embryos. The original text of section 11 provided both an absolute prohibition of embryo research and a provision permitting the licensing of such research together with the proviso that both clauses could not be in force at the same time. Thus, while the Government was clear when it introduced the Bill that legislative provision had to be made, there was less clarity as to the content of that provision. The uncertainty extends back beyond the drafting of the Bill itself. The Committee of Inquiry into Human Fertilisation and Embryology (the Warnock Committee) received representations from the public, deliberated the issues and reported in 1984.3 Yet this was felt to be insufficient consultation and a second document to elicit comment was published in 1986.4 Only after this second consultation did the Government feel able to publish its own proposals in a White Paper.s The primary reason for this reticence was the reluctance to deal with matters of conscience as Government proposals rather than by way of private members' bill. This in turn springs from the problems of identifying a consensus on such matters. In the event, the 1990 Act can be seen as providing an institutional framework in which compromises can be worked out rather than enshrining solutions to the disagreements.


Objective To study the efficacy of the hemapheresis in conjunction with chemotherapy for myeloproliferative diseases.Methords Hemapheresis was done once or twice weekly,followed by hydroxyurea chemotherapy in 38 patients with of myeloproliferative diseases.Results After therapeutic hemocytes apheresis,peripheral white blood cell counts of patients with CML decreased from(251.42±200.67)×10~9 to(100.31±31.28)×10~9,platelet counts of patients with ET decreased from(1527.3±243.5)×10~9 to(452.1±156.3)×10~9,hemoglobin concentrations of patients with PV decreased from(231.5±35.6)g/L to(152.2±19.1)g/L.Clinical symptoms of the patients improved dramatically.Conclusion This methord can relieve clinical symptoms rapidly.


With the expansion of the markets about near‐eye display devices and other similar consumer devices, the highly optical efficiency and display performance of these devices have also received more and more attention and challenge. So in this paper, a novel backlight unit for liquid crystal display (LCD) is reported. The angle of the radiation can change with the position of the active area (AA) in two directions. The change range of the chief radiation angle can vary more than ±20°. In the meanwhile, with the same power consumption, the brightness of the backlight can achieve or exceed the existing brightness level of the backlight.


The application of TA 3-D SRME on data acquired using multi-azimuth towed streamer configurations has led to significant improvements in multiple removal compared to the application on data acquired in conventional narrow-azimuth towed streamer mode. Multi-azimuth data from the Nile Delta is used to compare results between narrow-azimuth 3-D SRME and true-azimuth 3-D SRME. Multiples are among the toughest challenges in processing seismic data in the Nile Delta, which is characterized by a structurally complex dipping water bottom, shallow gas charged channel systems in a compaction driven overburden, overlying a complex anhydrite rich layer of Messinian age. This overburden generates complex diffracted multiples, both in the shallow section (water bottom multiples) and in the deeper section (Messinian peg-legs).


In the seed production system of the abalone Haliotis discus hannai, sessile algal communities on the rearing plates are classified into two categories; the first and the second phase algae. The changes from the firs to the second phase algae were observed in detail. On the rearing plates, Licmophora abbreviata, Achnanthes javanica f. subconstricta, A. kuwaitensis, Navicula ramosissima, Nitzschia closterium and N. acicularis were observed abundantly as the first phase algae, and they built up stratified overstory assemblages. After the introduction of juveniles of the abalone onto the plates, these algae disappeared, and Cocconeis costata, C. scutellum, C. sublitoralis and Myrionema sp. proliferated remazkably and assemblages became a uniform layer of prostrate cells. These second phase algae were seen in small numbers in the early stages before introducing the abalone juveniles. Without grazing pressure of the juveniles, the algal community on the plates did not change to a uniformly layered assemblage. The first and the second phase algae differed in community structure and dominant species. In addition to these differences, the second phase algae were characterized by the remarkable proliferation under grazing pressure.


Watermelon is the most significant, natural source of Lcitrulline, a non-proteinaceous amino acid praised for its ability to benefit cardiovascular health and increase vasodilation in many tissues of the body. Other cucurbits may also contain significant amounts of citrulline. XX genotypes were evaluated in triplicate in two environments to estimate citrulline amounts and variation due to genotype, replication, environment..... Introduction Watermelon is considered a functional food, owing its benefit to cardiovascular health, reduction of risk to several cancers, and increase of vasodilation in many tissues of the body (sources here). These properties are due to its high concentrations of lycopene and citrulline. Of particular interest in this study is citrulline, and its abundance in fruit of other genera and species in the Cucurbitaceae. Citrulline is a physiological amino acid with a high nitrogen to carbon ratio that benefits both plant and human health. In human health, citrulline offers many health benefits, with particular relevance in exercise supplementation for muscle performance and recovery (Perez-Guisado and Jakeman 2010, Tarazona-Diaz et al. 2013). Citrulline has been investigated in human diet more exhaustively to this end, but also in other human-health fields, including pharmacology (Rouge et al., 2007; Thibault et al., 2011; Levillain et al., 1997), immunology (Sureda et al., 2009), and neurology (Sase et al., 2013). Citrulline is a precursor to the semi-essential amino acid arginine, and pharmacological study shows that in diseases related to arginine deficiencies, supplementation with citrulline is often more effective than arginine itself. This is due to its more targeted metabolism, which contributes to increased bioavailability, better absorption into the bloodstream and reduced side-effects when administered orally (Tarazona-Diaz et al., 2013; Collins 2013; Bahri et al., 2013; Mandel et al., 2005; Oketch-Rabah et al., 2016). Metabolism and function of citrulline are well-studied in human and prokaryote systems. However, its production and role in plants is both less studied and more complex. Several studies considering physiological and environmental variables in watermelon suggest potential influences on citrulline abundance. Some research groups report a coaccumulation of both citrulline and arginine under salt stress in higher plants (Mansour, 2000; Ashraf and Harris, 2004). The few studies found in literature are, most appropriately, performed on watermelon and related species because of the high concentration in the fruit and leaves (cite). These studies show that in response to drought and high-light stress, citrulline accumulates dramatically in the leaves of Cucumis melo and some Citrullus species, suggesting its role in osmotic adjustment, radical oxygen species scavenging, and potential use as a biomarker for selecting tolerant cultigens (Akashi et al., 2001; Smimoff


Book Publisher: Cambridge, MA: Massachusetts Institute of Technology Press, 2002 481 pp., with indexes and references in each chapter. This book addresses the design, development, and use of software, integrating both a social sciences and a software engineering perspective, rather than presenting two parallel discourses. This approach overcomes the problems associated with leaving the integration to the pre-existing skills of readers in a fundamentally difficult task. As such, this book is immensely interesting, both to read and to use as a reference. The book consciously alludes to the title of Checkland's influential work, Systems Thinking, Systems Practice [1], and is a work worthy to bear a title making this allusion.


A simple reaction-type model that produces complete chiral symmetry breaking in crystallization is proposed. Crystals of homochirality are formed from achiral molecules. The model assumes i) perpetual mixing of the solution and abrasion of the crystals, ii) existence of chiral units smaller than the critical nucleus, iii) all processes have their counterparts, that is, decay of chiral units and crystals also occurs. We show that autocatalysis arises from the reaction of the chiral units so that chiral asymmetry is amplified as crystallization proceeds. Homochirality is achieved via slow relaxation in a later stage of crystallization.

This paper seeks to highlight a specific methodological approach to the use of ICT in the social sciences. The inclusion of new technologies in school is changing the form and manner of teaching. We propose a new line of research: the use of the documentary, which relates the audiovisual product, education and social science content through the transmedia narratives and resources accessible to students. This video technique allows the incorporation of many ICT tools, embedded in a concrete audiovisual history, countless possible work areas traditionally reserved to the textbook. In addition, throughout the process of developing the documentary, the students learn enjoy knowing and researching a topic, summarizes and condenses the collected ideas and transferred to a nearby language as the audiovisual. An experience that is being applied successfully in some school contexts and it's presented here for information and discussion.


The recombination activity of crystal defects was studied along cross-sections of cleaved multicrystalline silicon wafers (Silso®) grown by block casting. The temperature dependence of the electron-beam-induced current (EBIC) contrast c(T) was analyzed to study defect passivation by remote hydrogen plasma treatment with respect to (i) the extension and (ii) the degree of passivation. Based upon model calculations, the c(T) behavior allows estimating the degree of contamination of recombination active crystal defects. After hydrogen treatment of 1 h at 310°C the number of defect-related deep levels at grain boundaries is reduced by a factor of three to four. Low-temperature EBIC reveals that hydrogenation also reduces the density of active centers at defects which exhibit already very low or no (detectable) EBIC contrast at room temperature such as intragrain defects. Both defects in intragrain regions and grain boundaries are passivated down to about 100 μm. No indications were found for significantly enhanced hydrogen diffusion along grain boundaries.


Due to recent evolution of MEMS technology, wireless sensor nodes will be computing nodes having more storage space and processing power, and wireless sensor networks (WSNs) will be more capable of processing complex, cooperative tasks just in time, without relying on cloud servers which may cause delay and consume WSN bandwidth. However, low level implementation of cooperative applications onto individual sensor nodes needs a lot of human efforts, and has a considerable gap with high-level requirement given by application developers. To fill the gap, we propose a support environment for WSN applications development. We design a language to describe high-level specification of cooperative applications on WSN and provide an algorithm that translates the given high-level specification into program codes of sensor nodes. We have shown some example descriptions of highlevel specifications and have evaluated the quality of generated programs through several experiments.


Production scheduling is an important part of the production management in the manufacturing systems area for the reason that its main objective is to increase the productivity and to minimize the operating costs. In this paper it is presented a swarm intelligence approach over the job shop scheduling problem, by using Ant Colony Optimization and Particle Swarm Optimization techniques. Due to the high complexity of this problem an optimal solution, that solves the resources conflicts and minimizes the makespan and total completion time, is difficult to obtain. In this context a comparison between the two implemented techniques is presented in order to evaluate the performance considering different simulation production scenarios.


This study aims firstly at construction of models which can describe the difference of route choice behavior affected by toll charged among drivers with different values of time, and secondarily at assessment for effect of toll charged as a kind of road pricing on the improvement of road network traffic flow. It is however difficult to obtain the actual data concerning this, and hence this study tries to analyze fundamental properties of traffic flow situation caused by road pricing, using simulation analysis based on models constructed by an experimental questionnaire survey for route choice behavior. It is found that it would be recommendable to raise the toll level with the increase in the percentage of high penalty driver for minimizing the average travel time on the entire road network.


From the point of view of education, management is a system of concepts, methods, tools of orientation and leadership, coordination, used in achieving the objectives of education, at the level of expected performance. Management, in its current approach, finds a specific application in the field of education management, as a complex action of directing, designing and evaluating the training, development of the personality of each individual, according to formulated goals. The present study aims to identify the managerial style of teachers in an Arad high school, respectively which is the predominant managerial style, agreed by students. In this sense, the main tool used to identify the managerial style of secondary school teachers was a questionnaire consisting of 35 items in 5 steps of response on a likert scale. The results showed that although the authoritarian managerial style, from the point of view of holistic perception, is less agreed by students, when they relate to their favorite teacher, there is a weighted increase of 10 percent of this style.


The issue of effective land management is considered as an element of the region's sustainable development strategy. The current state of land use in the studied Arkharinsky district is studied. The main problems that have a negative impact on land management in the municipality under study are identified. The calculation of the coefficient of efficiency of management of land resources, the effectiveness of spending and funding for land cadastre and land survey, determined the complete financing of cadastre and land surveying work. Measures aimed at solving the identified problems are proposed. The effectiveness of land management can be improved in the following ways: by reducing the duration of activities; byincreasing the productivity of employees by reducing the loss of working time; by improving the quality of management decisions; by rationalizing document flow, automating information processing; improving management efficiency by more complete and timely collection and analysis of information on projects; creating opportunities for maneuvering financial resources.

This thesis investigates the connection between popular culture's perception of place and the physical augmentation of reality. Focusing on the top five tourist cities in America, this disparateness is observed through the lens of a souvenir: the snow globe. The presentation of the work is broken into two parts: the written portion and the book of diagrams. A total of 45 snow globes (9 for each of the 5 cities) were selected for the study, each carefully analyzed for content to include monuments, colors, text, dimensions, realism, and layout. This resulted in a series of diagrams which graphically express the information contained within the globes, as well as matrixes located in the appendices; the diagrams were created as a method to objectify the subject. The monuments depicted in the globes serve to narrow the scope of the study, bringing emphasis to those works of architecture only. The significance of the diagrams is explored in the written portion, associating the findings from the snow globes with the backgrounds of the cities. In addition, the written portion contains vital contextual information gathered from readings in subject areas including architecture, city planning, marketing, and snow globes. Tourist souvenirs are not designed with the intention of being accurate replications of the city – they are abstracted. However, they are abstracted precisely in a way which allows for the personality of the city to come through. Highlights and themes are selected, and the globes operate within these boundaries. This simplification illustrates what is crucial to defining the place. Snow globes have been a commonplace souvenir besought by tourists for a hundred years. Their notoriously kitsch craft is hardly considered to be a product of high design; however, snow globes can be employed as a form of diagram that assists architects in understanding the background of the place and how buildings fit into the urban context of the city, as well as the brand image of the city.


A minicell-producing strain of Salmonella typhimurium contains two cryptic plasmids. One has a molecular weight of 2.6 × 106 to 2.8 × 106, is present in multiple copies per cell, and segregates into minicells. The other has a molecular weight of 130 × 106, is present in few copies per cell, and probably does not segregate into minicells.


The seasonal changes in concentrations of copper (Cu), iron (Fe), zinc (Zn) and manganese (Mn) present in the milk of the three main milk-producing species (cow, ewe and goat) were studied for one year by using flame atomic absorption spectrophotometry. The mean concentrations obtained for the four minerals studied, Cu, Fe, Zn and Mn, were: 0.16 ± 0.03, 0.44 ± 0.11, 4.21 ± 0.41 and 0.026 ± 0.006 mg/kg of fresh weight respectively for cow milk; 0.41 ± 0.14, 0.77 ± 0.32, 5.66 ± 2.20 and 0.089 ± 0.028 mg/kg of fresh weight for ewe milk; 0.40 ± 0.07, 0.67 ± 0.12, 4.76 ± 0.50 and 0.155 ± 0.059 mg/kg of fresh weight for goat milk. According to these concentrations the consumption of a cup (250 ml) of cow's milk contributes 40 μg of copper, 130 μg of iron, 823 μg of zinc and 6.4 μg of manganese; in the case of ewe's milk the contribution is 100 μg of copper, 192 μg of iron, 1415 μg of zinc and 22 μg of manganese; and a cup of goat's milk gives 100 μg of copper, 167 μg of iron, 1190 μg of zinc and 39 μg of mangan...


The kinetics of the reactive diffusion at the liquid Al/solid Cu interface was investigated at T = 973 K, 1023 K, and 1073 K in a high magnetic field of 11.5 T. During the annealing process, three stable compounds (δ, ξ2, and η2) layers were formed at the interface of the couples, and a power function relationship between the mean thickness of the diffusion layers and the annealing time kept stable. Without magnetic field, the exponent of the power function for each compound layer was higher than 0.5, but it was close to or even smaller than 0.5 with a magnetic field. Compared with the field-free environment, the migration of the liquid/solid interface due to interdiffusion decreased in the presence of a magnetic field. A considerable decrease in the effective diffusion coefficient under a magnetic field provided a likely explanation for the experimental results.


In this paper, we prove the existence of weak solutions to the complex m -Hessian equations in the class D m (cid:2)) on an open subset (cid:2) of C n . In the end of the paper we give an example shows that in the unit ball B 2 ( 0 , 1 ) ⊂ C 2 the complex Monge-Ampère equation ( dd c .) 2 = μ is solvable but the complex Hessian equation H 1 (.) = μ has not any weak solutions where μ is a nonnegative Radon measure on B 2 ( 0 , 1 ) .


Objectives: This research attempts to figure out a comparative pattern of the social response from the peoples of Bangladesh as well as different communities and regarding actions taken by the government during the COVID-19 pandemic in Bangladesh. Else, this study also investigates the shortcomings of the different wing authorities of the Bangladesh Government to reach people of every corner of this country. Methods: In this research, different facts are analyzed from a statistical point of view. Authentic sources like reputed national and international newspapers, governmental release documents, release notes of WHO, etc. were considered for data collection to realize this country's preparations against the COVID-19 pandemic. Results: From the statistical analysis, this study found that different government authorities partially failed to communicate the measures of the government to the wider public audience. This study has shown that having more tests could have prevented the spread of the virus in Bangladesh. The strong lockdown measures taken by the government were not enough as the population of this country is huge and it is really difficult to maintain social distance in a densely populated country like Bangladesh. Conclusions: The socio-economic condition and decision-makers' shortcomings could have been overcome if the right plan and action had been taken at the right time. Until the vaccine is available it is recommended that people should keep social distance while going outside, using masks and protection should be mandatory. Furthermore, more health care professionals should be hired and trained to fight this virus. Doi: 10.28991/SciMedJ-2021-03-SI-4 Full Text: PDF


Swelling and fibrillation of two kinds of lyocell, and , were investigated using polarizing and scanning electron microscope (SEM). of a representative lyocell showed that loop tenacity which is related to wrinkle and resilience of fiber does not show significant reduction in wet state. Two kinds of lyocell exhibited surprising degree of swelling in aqueous NaOH solution under free tension. Diameters of and swelled up to 670% and 830%, respectively in the range of around 10% NaOH concentration. Molecular orientation estimated by birefringence also reduced remarkably in alkaline solution. Moreover, diameter and birefringence which changed in alkaline solution did not recovered to original level even after washing and drying. Fibrillation of fiber observed by SEM seems to be easier than that of . In order to understand the difference between and , further study on the structure of the two fibers will be followed.


To elucidate biochemical mechanisms underlining high plasma glucose in chicken embryo, gene expression profile of gluconeogenic key enzymes were characterized. The liver and skeletal muscle were collected from 13to 21-day embryos (E) (n=8) of layer chicken and the mRNA of pyruvate carboxylase (PC), cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C), mitochondrial phosphoenolpyruvate carboxykinase (PEPCK-M), muscle-type fructose-1,6-bisphosphatase (mFBPase), liver-type fructose-1,6-bisphosphatase (lFBPase) and glucose-6-phosphatase (G6Pase) were measured by real-time PCR. All the enzymes were expressed in the liver, whereas in the skeletal muscle, only mFBPase and G6Pase were detected. In the liver, all the enzymes except for G6Pase peaked either on E13 or E15. G6Pase expression was the highest between E15 and E19. In the skeletal muscle, mFBPase peaked on E19 and G6Pase peaked on E15. These results suggest that gluconeogenesis is active in chicken embryos but regulations of mRNA expressions of the gluconeogenic key enzymes are different between liver and muscle. The results also suggest that the skeletal muscle, which is generally not regarded as a tissue conducting an active gluconeogenesis, may contribute to the regulation of embryonic plasma glucose to some extent, and warrant further investigations of the presence of enzyme activities.

Abstract Forecasting the nocturnal minimum temperature under clear sky conditions is of great interest in case of spring frost, but generally it is difficult to do with accuracy; the main reasons are the large temperature decrease resulting from a large radiative deficit, the strong stability of the atmospheric boundary layer, and the great influence of local conditions (soil and environment). A way to overcome these difficulties is to set up specialized prediction models. Proposed here is a local model that works with simple input data and observations, all collected from a meteorological station, but it includes, at the same time, a detailed description of the different energy exchanges in the nocturnal boundary layer (0–300 m) and in the soil (0–1 m): an original radiative transfer scheme describes the evolution of atmospheric radiation, a first-order scheme simulates the progression of cooling in the atmospheric layers, and a simple parameterization of heat transfer in the top soil layers accounts for...


Ecological specialists have an important role to play in achieving the Sustainable Development Goals adopted by the United Nations. To do this, they need not only professional, field-specific (hard), skills but also universal, meta-subject soft skills. The article presents the results of a survey study of the attitude of students, future ecologists (229 respondents), to the formation of soft skills in the educational process. The data obtained are generally consistent with the well-known models of flexible skills (in particular, "4Cs"), as well as with the core competencies for sustainable development proposed by UNESCO. It seems appropriate to intensify the actions of the academic community (university and college administration, teachers, tutors, authors of textbooks, etc.) aimed not only at the development of students' environmental self-awareness, but also at the practical development of their abilities necessary for systematic, critical and creative, individual and team identification, solution and prevention of environmental problems of various scale and level in conditions of uncertainty.


Soil pH is a measure of soil alkalinity or acidity. It is a significant indicator of soil health. The acidic soil (low pH value) constitutes much of the areas of Jorhat district with proportionally small areas of neutral soil. The 'r' value
 of -0.538 with 'P'value of 0.0365 express the existence of almost a strong negative as well as significant relationship between fertilizers consumption and pH value of soil. The dominance of highly acidic soil in the southern and central part of the
 Jorhat district portrays normally limited suitability (Low productivity) of soil for the cultivation of paddy (rice). Though most the areas in the northern part of Brahmaputra river (i.e. Majuli island) constitutes highly productive (production per
 ha) soil for paddy cultivation.


We present a new method for constructing solutions to nonlinear evolu-tionary equations describing the propagation and interaction of nonlinear waves. In the present paper, with the help of some simple examples, I demonstrate a new approach to the construction of asymptotic solutions to differential equations. I choose very simple examples (the Hopf equation and its multidimensional analog) and, on purpose, omit details in the proofs of estimates (which are obvious here). Usually, by saying that a function is an asymptotic (approximate) solution of a differential equation, we mean that this function satisfies the equation with a small discrepancy. The smallness of the discrepancy is understood as the smallness in some uniform metric under the assumption that a small parameter tends to zero.


It is found that moisture absorption by highly cross-linked epoxy-amine resins results in a reduction of strength and elastic properties. This eefect is explained mainly by the plasticizing effect of water. T g is reduced by 50 to 80K, which in turn reduces static modulus, yield stress and tensile strength at room temperature. Moisture absorption also results in the increase of low frequency dielectric losses, more pronounced in fibre composites

ocated in more than 130 countries, migrant Filipina domestic workers have settled in the cities of Athens, Bahrain, Rome, Madrid, Paris, Toronto, New York, Los Angeles, Hong Kong, and Singapore. Dispersed among a multitude of industrialized nations, they have come to constitute a diaspora more precisely, a contemporary female labor diaspora.' A particular result of global restructuring, this labor diaspora is a product of the


A lack of engagement with the theology of evil and suffering leads to immature responses when tragedy strikes our congregations and alienates the sufferers among us. I believe the best path forward is an interdisciplinary approach that is both intellectually honest and spiritually classical rhetorical studies and modern psychological trauma theories in order to demonstrate how Job's deep lament offers the Church an example of how to give sufferers the space to work through their grief as they walk their path towards healing and hope.


BACKGROUND
Autophagy-related genes ATG4B, ATG7, and ATG12 have been identified to play a critical role in viral replication. However, these genes have yet to be identified in hepatitis B virus (HBV).

OBJECTIVE
To characterise the role of ATG4B, ATG7, and ATG12 genes in HBV infection.

METHODS
The mRNA expression was examined by quantitative real-time RT-PCR and Western blotting. Short hairpin RNA (shRNA) of the target gene was used to examine the function of the gene in HBV replication. Evaluation of HBV DNA level was performed by real-time PCR.

RESULTS
Our findings revealed that ATG12 gene expression was significantly up-regulated (p < 0.005), whereas ATG7 gene expression was down-regulated (p < 0.0001) in HepG2.2.15 cells when compared to HepG2 cells. However, no significant difference in mRNA level of ATG4B was observed. These results were consistent with protein level findings. Moreover, we analysed the function of ATG12 in HBV replication by using ATG12 shRNA and evaluated HBV DNA level. We found that the amount of HBV was decreased in ATG12-knockdown HepG2.2.15 cells when compared to control HepG2.2.15 cells (P < 0.05). The mRNA expression of interferon-alpha (IFN-α), interferon-beta (IFN-β), and interferon-inducible genes (IFI) was also investigated. Our results showed that the expression of IFN-α, IFN-β, and IFI27 genes were increased in ATG12-knockdown cells but not in Mx1 gene when compared to control cells (p < 0.005, p < 0.0001 and p < 0.005, respectively).

CONCLUSION
These autophagy-related genes, ATG12 may play a role in HBV replication via impairing IFN pathway. However, the biological significance of other autophagic genes such as ATG7 warrants further study.


Purpose – The purpose of this paper is to address limitations of prevailing approaches to leadership development programmes and make suggestions as to how these might be overcome. These limitations are an outcome of the dominant rational functional approach to leadership development programmes. Based on empirical research, and underpinned by organisational theory, the paper suggests a shift towards a socio‐constructivist perspective on design and implementation of leadership development programmes. The explorative study proposes that context and participant differences need to be recognised as factors impacting on the effectiveness of leadership development initiatives.Design/methodology/approach – The paper is based on a review of relevant literature and qualitative data collected using the case study method. The study presented is explorative.Findings – The paper finds that participant interaction with leadership development programmes varies depending on individual and/or contextual factors. Current de...


In this paper, the key ideas of ambient intelligence, wearable objects and service-oriented computing are combined so that appliances and devices can disappear and become part of the work garments and environment of the individual and, as an effect, services emerge to face risky situations through reaction to alarms and to perform risk management. Along this line, we outline the features of a wearable-based services system aimed at improving safety in work places.


Members of the signaling lymphocyte activation molecule (SLAM) family, including homophilic and heterophilic receptors, modulate a wide range of immune responses, including T cell activation and NK-cell activation. The SLAM family members share a similar ectodomain organization, with an N-terminal IgV domain and a C-terminal IgC2 domain. The sole exception is the Ly-9 ectodomain, which is composed of a tandem repeat of the IgV-IgC2 motif. The homophilic interaction is mediated by the first N-terminal IgV domain. The 2.0 Å crystal structures of the CD84 and Ly9 first N-terminal IgV domains reveal a similarly organized homophilic interaction with the recently reported NTB-A homophilic interaction, the differences in the homophilic interfaces is likely an important mechanistic feature that prevents the formation of undesired heterodimers among the SLAM family receptors. Notably our biochemical data also indicated the strong self association of CD84 and Ly9 with a Kd in the sub-micromolar range. The fact that the homophilic affinities span over three orders of magnitude among the SLAM family members suggests that the difference in the affinities might be a contributor to the different signaling behaviour exhibited by the individual family members.


Objective To discuss the clinical effects of different intensive insulin therapy in the treatment of type 2 diabetes mellitus(T2DM). Method 126 patients with T2 DM were randomly divided into group A, B and C. Group A patients were treated with intensive therapy of insulin aspart with insulin pump, group B patients were treated with insulin aspart + bedtime insulin glargine subcutaneous injection therapy daily, group C patients were treated with insulin aspart 30 subcutaneous injection daily before meals, FPG, 2h PG, Hb A1 c and HOMA-IR were contrasted among the three groups before and after treatment, and standard time of blood glucose, insulin dosage of maintain blood glucose and incidence of hypoglycemia were contrasted among the three groups. Result There were no significant differences in FPG and 2h PG among the three groups before treatment(P 0.05), levels of FPG and Hb A1 c after treatment were significantly lower than before treatment, and the levels of FPG and 2h PG in group A were lower than group B and group C(P 0.05). There was no significant difference of Hb A1 c and HOMA-IR among the three groups before treatment(P 0.05), but after treatment, the above indexes were sighificantly lower than before treatment among the three groups(P 0.05), there were no significant differences after treatment among the three groups(P 0.05). There were significant differences in standard time of the blood glucose and insulin dosage among the three groups(P 0.05). There was no significant difference in incidence of hypoglycemia among the three groups(χ2 = 0.392, P = 0.072). Conclusion Insulin pump intensive therapy with aspart insulin dose and basal dose and pre-meal dose 1 ︰ 1 can more quickly control the blood glucose level to the target value, and can reduce the dosage of insulin in the treatment of patients with T2 DM, worthy of promotion.

Hume's Treatise of Human Understanding (1739-1740) was published in the midst of a century of dramatic literary, political, and moral change. Banwart argues that interpreters of the Treatise have focused too exclusively on the causal influence of constantly conjoined experience on the imagination. When causality is restored to its social context, we can see that imagination is influenced not just by regularity but also by familiarity, by the contiguity and resemblance of other people. Our ability to see a resemblance is more basic than our ability to make habitual associations. It affects and is affected by those who teach us to attend to experience in particular ways. Acknowledgement of the social origin of ideas calls us to be more responsible for correcting our beliefs and for maintaining genuine conversation with our community.


The challenge of reconciling competing demands for national economic growth, wildlife conservation and the wellbeing of local communities is widely recognised. In Chiawa, Zambia 2013 this challenge is particularly acute, as a new highway and bridge promise to reverse the area's historical marginality, promoting it as a premier site for safari tourism and agri-business. High profile conflicts over land rights, however, indicate local people's fears that this will accelerate dispossession, with profits accruing to outsiders and the community seeing little if any benefit.


Lung cancer remains the most common cancer and the leading cause of cancer-related mortality. Despite continuing improvements in chemoradiotherapy regimens and the recent clinical validation of particular agents as maintenance treatments in advanced disease, there remains an unmet need for new therapies with clinically proven value in the treatment of unresectable stage III NSCLC. Studies are under way to determine whether the use of anticancer vaccines may be an effective strategy in the treatment of NSCLC.


By substituting passive components in electric traction vehicles for new circuit solutions based on power electronics, new possibilities to develop more effective vehicles are introduced. At single-phase line voltage the power is pulsating with twice the line frequency. This power pulsation is generally eliminated by a passive short-circuit link placed in the DC link of the traction drive. The paper presents a possibility to exchange the passive short-circuit link for an active filter. The active filter enables operation at both 16 2/3 Hz and 50 Hz supply frequency. This is especially attractive for two frequency locomotives. Principle rules of design and control as well as important parameters for the design of the active filter are described. Computer simulations verify the function.


A series of experiments was conducted to study the base composition of DNA in AVl2-induced tumor and host cells by paper chromatography, and it was found that DNA per cent. guanine-cystosine contents were around 42 % in both of them. The base composition of DNA of AV12 itself differs considerably from that of AVl2-induced tumor cells, while
the DNA of tumor cells shows the property similar to that of host cell DNA. The genetical relationship among virus, host cells and tumor cells was discussed.
