Heluany-Filho, Mário Augusto. Use of a symbiotic product to decolonize patients harboring multidrug-resistant Gram-negative bacilli. Master of Sciencethesis– Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, 2016. In recent decades the incidence of multidrug resistant (MDR) Gram-negative nosocomial infections has been dramatically raising in the whole world. The World Health Organization (WHO) recently recognized nosocomial infections due to MDR pathogens as a global concern due to its negative impact on patients, health-care workers and health-care institutions, affecting developed countries as well as developing ones. They negatively impact in-hospital mortality and health-care related costs. Hand hygiene promotion, antibiotic stewardship and contact precautions are the main available measures to control such MDR Gram-negative organisms in hospitals. However, they are only partially effective as well as difficult to be implemented and expensive. Therefore, simpler and more effective actions are thought to be helpful and urgent. In the present study, we analyzed the impact of the administration of a symbiotic product on patients harboring Gram-negative multidrug-resistant bacteria upon the subsequent rates of decolonization of these pathogens from the gastro-intestinal tract.This is a double-blinded and placebo controlled randomized clinical trial evaluating the oral/enteral daily administration of 10 10 units of Lactobacillus bulgaricusplus 10 10 units of Lactobacillus rhamnosus associated with fructo-oligosacharide (FOS), or placebo, for 7 days, to 101 patients previously colonized by MDR Gram-negative bacteria, identified through selective culture of rectal swab. The primary study outcome was the rate of complete decolonization of the MDR microorganism from the gastro-intestinal tract following the intervention. In the "modified intention to treat" analysis, decolonization rates observed were 16.7% (8/48) in the experimental group and 20.7% (11/53) in the placebo group (p=0,600). In the "per protocol" analysis, decolonization rates were 18.9% (7/37) in the experimental group and 23.3% (7/30) in the placebo group (p=0,659). In a logistic regression model, symbiotic use did not produce any impact on the chance of decolonization (OR=0.80, CI95%=0.28-2.27, p=0.678). Mild to moderate adverse events occured similarly in both the placebo (7.55%) and the experimental group (6.25%), (p=1,000). No severe adverse event potentially related to the medications was detected during the study period. In the present study conditions, the results obtained lead to the conclusion that the studied symbiotic proved to be ineffective to decolonize patients harboring multidrug resistant Gram-negative bacilli.

Operating of electric power systems is becoming more and more complex and is posing more and more challenges every day as they are operated close to their stability limits. Electrical power systems are expending (renewable energy source RES, distributed generation DG, independent power producers IPPs, etc. which are often no dispatchable or controllable generation) while the energy market (generation, distribution, transmission) is deregulated. In addition, regulatory pressure tends to focus power system operators attention to grown the Return of Investment of their assets while power consumption is increasing and power system infrastructures are aging. On the other hand, the demand for higher reliability and power quality is increasing as power electronics driven sensitive loads are added by the industrial consumers. Power electronic converters can be found wherever there is a need to modify the electrical energy form (i.e modify its voltage, current or frequency).


The recent development in the stock market and the economic growth of the nation attracted many new investors across the world. This has further encouraged the capital market to get wonderful performance, especially in Primary Market through IPO. The corporate companies and the government institution raise finance through equity and/or debt. And the unlisted companies acquire the capital by issuing the shares through Initial Public Offering (IPO) in the primary market. In the recent past, in spite of having uncertainty in the various investment avenues, IPO and its post-performance have yielded a competent return. The paper focuses on analysing the performance of post-listing of IPOs in the national exchange which were listed in the calendar years 2021 and 2022. The data assembled for the research is based on secondary sources. Various statistical tools are used for conducting the research. Further, it intends to measure the value of share premiums and share pricing on listing day, as well as the IPO return's progressive increase. The study also attempts to assess if these IPOs were under-priced in the short run, as well as identify key factors that influence the short-term movement of such IPOs. The study may also bring some inputs to possible investors to decide to invest in IPOs.

His aim is to promote textile making, working with hands and related tools while also promoting textiles as a collaborative, contemporary practice, which is influencing other disciplines. The sensorial loop references the idea that 'the end of which is connected to the beginning'. It references the expressive and physical loop of know-how, ideas and memory and processes.


IP Spoofing is the concern of security in which IP addresses get compromised and attacker will use it to perform DOS attack. Thus, filtering of packets and providing security so that only authorized and verified IP addresses will get access and rights for packet transmission and reception is the today's demand. This paper proposed survey on existing algorithms, gap analysis in existing research and the scope for further implementation to detect DOS attack origin by finding source attacker using IP trackbacking and packet marking. Keyword: DOS attack, IP Traceback, Packet Marking, attack graph, IP spoofing.


This project was to improve the quality of local road expenditure data. The Australian Local Government Association uses local road expenditure collected for ALGA by the State and Territory Grants Commissions, Western Australia Local Government Associations and Australian Capital Territory Department of Urban Services for the National Local Road Data System (NLRDS). The National Transport Commission uses local road expenditure data collected by the Australian Bureau of Statistics for the Commission's PAYGO vehicle charging model. This project was to survey a sample of councils to obtain greater detail on the NLRDS expenditures categories to allow disaggregation of it into the expenditure categories used by the National Transport Commission for its PAYGO model. The project developed methodology to derive greater detail for local road expenditure data from a sample survey and provided improved local road expenditure data in the expenditure categories used in the PAYGO model. The project also identified a methodology for estimating the activity life cycle costs of local roads for a sample of councils that may be attributed to major users of local roads being local (residential) use, regional (business/commercial) use and higher mass vehicles.


The scaleup of three Fe{sub 3}Al-based alloys at several commercial vendors is described. The scaleup processes examined the effect of crucible materials (MgO versus Al{sub 2}O{sub 3}), melting practice, vacuum-induction melting, vacuum-arc remelting, electroslag remelting, and processing under commercial conditions. Each alloy is designed for a specific use: sulfidation resistance, room-temperature ductility, and high-temperature strength. One of the alloys was also scaled up through powder production by nitrogen-gas atomization. The scaled-up heats varied in size from 50 to 250 kg (100 to 500 lb). The ingot sizes varied from 38- to 203-mm (1 1/2- to 8-in.) diam. The scaleup processes occurred at Ametek Specialty Metal Products Division; Haynes International, Inc.; Carpenter Technology Corporation; Special Metals Corporation; and Precision Rolled Products, Inc. The processing of 102-mm-diam (4-in.) ingots at the Oak Ridge National Laboratory into plate and sheet is described in detail. Tensile and creep data on a large powder-metallurgy and cast-and-worked alloys are presented. Recommendations are made for future work on the heats scaled up in this study. 2 refs., 25 figs., 6 tabs.


3-Phenyl-6-methyl-4(3H)-quinazolinone-2-yl-mercaptoacetic acid hydrazide (3) was reacted with substituted aldehydes in absolute ethanol to obtain a new series, 3-phenyl-6-methyl-4(3H)-quinazolinone- 2-yl-mercaptoacetic acid arylidenehydrazides (4a-q). The structures of 4a-q were elucidated by elemental analyses and from spectrometric (UV, IR, 1H-NMR, 13C-NMR and EIMS) data. Then 4a-q were evaluated for antibacterial, antifungal and antitubercular activities. No significant activity was observed against the selected microorganisms.


Since there is a great confusion between the ontologies and other semantic resources, the purpose of this special issue is to address the question on "Ontologies and terminologies: Continuum or dichotomy". We have selected five articles which study the differences and similarities between these semantic resources. More particularly, the articles are dedicated to the differences existing at the level of terms and of relations, the use of the ontologies on corpora and the dynamic and static representation of the knowledge.

One quorum sensing (QS) system in bacteria measures diffusible signal molecules called N-acyl-homoserinelactones (AHLs). At threshold concentrations of AHLs, activation or repression of genes as a function of the cell population density can coordinate disease progression or symbiosis in eukaryotic bacterial pathogens. The production of AHLs by plant bacterial endophytes has not been investigated even though they are commonly isolated from internal plant tissues. In this paper, we isolated and identified endophytes from sugarcane and grape plants, to determine if the endophytes produce AHL signals. Samples were collected from stem tissue of sugarcane and from xylem fluids of grapevine. Culturable bacterial isolates were purified by repeated subculture and the genus and / or species of the endophytes were identified by sequence analysis of the v3 (variable region) of the 16S rDNA gene. Using these analyses six unique isolates from sugar cane and seventeen isolates from grape xylem sap were identified. The production of QS signals by the sugarcane and grape endophytes were tested using five different AHL-dependent bacterial biosensors strains. Among the endophytic strains identified, five of six sugarcane and fourteen of fifteen of grape elicited a significant response in at least one AHL-dependent biosensor.

Adrenal gland involvement in Parkinson's disease was reported by different authors. Further studies became relevant after adrenal was proposed as dopaminergic donor for neurotransplantation. Chromaffin cells were grown in culture and the effects of nerve growth factor (NGF) tested: no differences were observed between parkinsonian and control cells. The expression of the beta-NGF mRNA in the parkinsonian adrenal was analyzed: a specific cDNA was synthesized and a 168 bp portion amplified using PCR. The products were identified and the identity of the fragment was confirmed by sequencing. Quantitative PCR demonstrated a beta-NGF mRNA concentration exceeding 5 fg/micrograms of total adrenal RNA. These findings demonstrate the retained functional capacity of the parkinsonian adrenal to respond to NGF and express the beta-NGF mRNA.


The article examines the anthropological origins and nature of human rights, as well as derivatives of the phenomena of power and State in their relationship with the natural human rights and interests. Concluded that genetically inherent nature of fundamental human rights, and their satisfaction with primary function is defined by the rule of law. The State and power serve as a social mechanism for equitable distribution of human resources and social reproduction of society. N eoinstinctual approach to understanding power as a mechanism for sorting and distribution of values gives clear answers to such questions. Thus, elders individualized power seems primarily as ownership and capacity to manage these essential resources of life, the wisdom of generations, historical experience, the ability to forecast revenues and allocate time primary resources of life – values-things. Personified power of a charismatic leader is extremely scarce possession of spiritual values, aims, in particular, hope and faith in the "bright future" confidence to overcome any adversity. Institutionalized government elected (appointed, inheritance, etc.) is provided officials it available to the public the value of instruments - laws, rules, regulations, opening wide access to primary values-things. The same authority shall mean the presence of its carrier and tool of spiritual values that are impossible or extremely difficult to get much of society. The state as a political institution in its origins has instinctively caused Institute of Human Rights and built on its system of values that crucially affect not only the formation of state institutions, but also on its structural and functional building, the type of political regime, especially the power relations etc. The need for the orderly distribution of resources is an important feature of life biogenesis Earth – harmonious existence of wildlife. A slight breach of «fairness» of this distribution may lead to the extinction of entire species of flora and fauna cardinal same offense to cause global catastrophe biosphere. The «wild» conditions this function is performed by natural selection. In a politically organized society core values of social justice not only makes the institutionalization of government and state, but also creates a societal function normalization and equitable (in terms of the dominant sectors of society) allocation of scarce resources, values as rational-legal mechanism of realization of natural rights. And the more the state is based on the Institute of Human Rights, the more it becomes legal and signs of a democratic state

Duodenal Varices can result from portal Hypertension regardless of the etiologies of liver cirrhosis. Bleeding from duodenal varices is rare but often severe and life threatening. Treatment modlities of duodenal varices include endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt, and surgery. As an initial treatment, endoscopic sclerotherapy is recommended due to easy accessibility but has limited success in controlling active vances can result from portal hypertension regardless of the etiologies of liver cirrhosis. Bleeding from duodenal varices is rare but often severe and life threatening. Treatment modalities of duodenal varices include endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt, and surgery. As an initial treatment, endoscopic sclerotherapy is recommended due to easy accessibility but has limited success in controlling active duodenal variceal bleeding. In this case, we report a spurting duodenal varix treated with Histoacryl injection in a 48-year-old woman with secondary biliary cirrhosis. Endoscopic sclerotherapy with Histoacryl is a useful therapeutic measure in the treatment of bleeding duodenal varix.


Basic information about the taxonomy, biology and distribution of Hyalinobatrachium glassfrogs of the Guiana Shield (GS) is scarce, ambiguous, and in many cases even contradictory. In this review we aim to clarify the current taxonomic status of this group by means of phenotypic (morphology, morphometrics and bioacoustics) and molecular (mitochondrial DNA sequences) comparisons. Eight species have previously been recognized for the GS: H. crurifasciatum, H. eccentricum, H. fleischmanni (initially described as Hylella cappellei in the GS), H. iaspidiense (with the putative synonym H. nouraguense), H. ignioculus, H. mesai, H. mondolfii, and H. taylori. Our data support the resurrection of H . cappellei from its synonymy with H. fleischmanni. Hyalinobatrachium crurifasciatum, H. eccentricum, and H. ignioculus are proposed as junior synonyms of H. cappellei. We show that none of the four paratypes of H. taylori belong to this species and we assign two to H. cappellei and two to H. mondolfii. Additional specimens previously identified as H. taylori are reassigned to H. cappellei, and hence H. taylori is redefined. Hyalinobatrachium nouraguense is confirmed as a junior syn


The COVID-19 pandemic and ensuing lockdown measures have led to an increase in e-shopping. Using longitudinal data from before and during the pandemic, we find that the number of respondents who shop online at least once per week increased nearly five-fold between Fall 2019 (11.6%) and Spring 2020 (51.2%). We conduct a series of ordered logistic regressions to establish who is responsible for this recent rise in e-commerce and to determine whether it will be temporary or longer-lasting. We then discuss the equity implications and urban and regional restructuring that this change in e-shopping behavior may entail.


Many soil physical and chemical properties interfere with landmine detection. Prior knowledge of these properties would improve detection technology selection and increase demining safety and efficiency. Developments in rapid mapping of these properties over wide areas is essential to meet military and economic constraints. Fusion of multiple detection technologies is also essential to overcome detection signal interferences. For these purposes, rapid mapping by use of remote sensing is being tested, starting with electrical conductivity mapping by radar remote sensing. Laboratory induced-polarization (IP) is also being tested to develop techniques to discriminate between electromagnetic signals from metallic particles in landmines and in soil, for regions with detection interference. Key physical models of soil are being developed for fusion of various landmine detection systems and to explain remote sensing responses to soil. Radar satellite tests carried out over the Canadian Forces Base Suffield (CFBS; Alberta, Canada) in 2004 and 2005 indicated 10 areas for possible high clay content and electrical conductivity. Eight of these were validated by soil maps and Landsat clay images. Two had high organic content with physical characteristics not known at present. Studies on soil with fine-grained iron-oxide powder and on iron with varied degrees of corrosion show that spectral-IP is sensitive to iron or iron-oxides regardless of their state. Soil has layered structure consisting of various grain-size combinations, but its physical characteristics are significantly influenced by whether its clay content is above or below a critical clay content (15 to 25 %). Results of these tests are discussed in this paper with explanations using the soil physical model.


THE danger of high-altitude flying to patients with sicklemia, until lately, has been more theoretical than.real. As recently as 1951 Margolies1 said that "the sickle cell trait is not a contraindication to high altitude flying." This statement was based principally on studies by Henderson and Thornell2 and Findlay, Boulter and MacGibbon,3 as well as on the fact that few published reports linked sickle-cell crisis with airplane flights. Sullivan4 (1950) described a young sicklemic patient who apparently had episodes of splenic infarction after each of two airplane flights over the Rocky Mountains; this was regarded as a chance occurrence. Recently, however, . . .

The role of an electronic government in a qualitative increase of citizens' engagement in public and political life has been noted.


The present observations and analyses were made as a continuation of the study on "Noise Attenuation in Shallow Holes (I)" (T. HIRONO, S. SINEHIRO, M. FURUTA and K. KOIDE, 1968). The test site was moved to the Onahama Weather Station on the Pacific Coast of Northeastern Japan, where the seismicity is high. The magnification of seismographs at the station, however, is limited only to 100 around a period of 1 sec owing to high background noise. The instrumentation and method of analyses were basically the same as in the previous study. In the present study, more efforts were made to study the reduction of amplitudes of earthquakes in depth to discuss the change of the signal to noise ratio (S to N ratio) with depth in detail. The results are summarised in the following: 1) The relations between noise attenuation and depth with frequency as a parameter show the same characteristics as in previous observations. Namely, the attenuation is higher with greater depth and with higher frequency. Especially, the noise attenuation becomes discontinuously higher, when the bore-hole seismograph reaches the tertiary bedrock at a depth of 75 m (Fig. 4 and Fig. 5). 2) The surface noise in the quiet nighttime diminishes to about * formerly K . Koide 550.340 a half of that in the noisy daytime in a high frequency range of 6— 10 cps; no difference, however, is found in a low frequency range of 0.63-4 cps (Fig. 3). 3) The shock-type noise due to trains, motor vehicles or dropping weights attenuates rapidly with depth and cannot be noticed above the stationary noise at a depth of greater than 75 m (Table 3). 4) At depths of 10, 20, 85, 50 and 100 m, earthquakes were recorded with adequate amplitudes, and the same analysis was applied to these earthquakes as to background noise. No appreciable difference due to azimuth, epicentral distance or P and S waves is found in the reduction of eathquake amplitudes in depth with frequency as a parameter. Generally, the reduction of earthquake amplitudes is greater with greater depth and higher frequency (Fig. 7). 5) The signal to noise ratio, in which attenuation of background noise and reduction of earthquake amplitudes with depth are taken into account, is much improved when the seismograph reaches the tertiary bedrock at a depth of 75 m (Fig. 8). Although no significant improvement in the S to N ratio is found in a low frequency range as was the case in the previous study, a higher detectability for local earthquakes can be expected from borehole seismographs, considering the improvement in the S to N ratio in a high frequency range of 2 cps-10 cps at a depth of 100 m by a factor of 3 or 4. 6) To ensure a higher detectability of local earthquakes for purposes of routine observation, the bore-hole seismograph was connected with a recorder of the routine type, and the seismograms were interpreted and compared with those obtained by the conventional seismographs at the surface. The number of local earthquakes (S—P <20 sec) detected by the bore-hole seismograph was 2.2 times as that by the ordinary seismographs, and the interpretation became much easier because of lower background noise (Fig. 10). This increasing rate corresponds to a reduction of the lower limit by 0.3-0.5 in magnitude of detectable earthquakes. This value is reasonable from the our improvement in the S to N ratio, if the frequency distribution of earthquakes of log Na=a-0.8M is assumed. By further suppressing the magnification of seismographs in a frequency range of microseisms, a still higher S to N ratio will be expected for local earthquakes. 1969                  Noise  Attenuation  in Sh訊llow  Holes(II)                   191


The temporal behavior of the population density of the first excited level of the hydrogen atom in a pulsed discharge plasma of a helium and hydrogen mixture has been measured using the laser induced fluorescence technique, while the population densities of the higher excited levels have been determined from the emission measurements. The population density of each level shows a rapid enhancement in the early stage of afterglow. The experimental results are compared with the collisional-radiative model, including various dissociation processes of hydrogen molecules. The experimental results can be explained well with the model. The population mechanism of the first excited level in the afterglow is found to be sensitive to the optical escape factor of the Lα line

Software renovation [35] Reverse engineering is to analyze the source code of legacy software systems in order to retrieve their high-level design, and other relevant information. Re-engineering continues after reverse engineering, to adapt the derived abstractions to radically improve the functionality and non-functional quality attributes of a software system, after which an improved system will be derived. For any of the above areas it is interesting to maximize the number of tasks that are automated during the engineering processes. Automation of a task is expected to improve both efficiency of the task itself, and possibly also some quality attributes of the resulting software. Examples of such attributes are correctness and tractability: trivial inconsistencies made by humans are avoided and automated processes can be traced and repeated more easily than human activities. We use the term meta program to refer to programs that automate the manipulation of source code. Thus we call the construction of such programs meta programming. Many meta programs have been and will be developed to support the above engineering disciplines. Figure 1.1 sketches the domain, displaying all possible automated transitions from source code, via abstract representations, to documentation. Each of the above areas highlights and specializes a specific part of the graph in Figure 1.1. For example, reverse engineering is the path from source code, via several abstractions to documentation. In reverse engineering, extensive analysis of source code abstractions is common, but the other edges in the graph are usually not traversed. On the other hand, in model driven engineering we start from documentation, then formalize the documentation towards a more machine oriented description, before we generate actual source code. The example languages for each tier are meant to be indicative, but not restrictive. A specific language might assume the role of source code, abstraction or documentation depending on the viewpoint that is imposed by a particular software engineering task. Take for example a context-free grammar written in the EBNF language. It is source code, since we can generate a parser from it using a parser generator. It is also an abstraction, if we would have obtained it from analyzing a parser written in Java source code. It serves as documentation when a programmer tries to learn the syntax of a language from it.


1.INTRODUCTION Since the 3D watermarking was firstly introduced by Ohbuchi , it is becoming an active research area during the last decade. 3D watermarking is inspired from the image watermarking and video watermarking. The techniques in 2D watermarking can not be directly applied to 3D watermarking. Generally speaking, the 3D watermarking can be classified into transformed domain watermarking and the spatial domain watermarking from the perspective of the embedding domain. Then the transformed domain methods can be further split into spectral methods and multiresolution methods. In this chapter, I will firstly comprehensively survey the transformed domain methods followed by that of the spatial domain methods. We focus mainly on the robust methods and briefly mention the others. Then we introduce the assessment methodology of the 3D watermarking algorithms.


This article is devoted to the development of algorithms for the adaptation of mathematical educational content and their implementation in the e-learning system. The adaptation of a mathematical content consists in the selection of an optimal edition of the material that best suits the individual characteristics of the student. The novelty of the work is the organization of the adaptation algorithms of the educational content in a three-level system: "introductory content adaptation" (an adaptation of the content of introductory materials of the discipline based on the initial level of students) - "current adaptation of the content" (an adaptation of the mathematical content based on current effective actions of students in the electronic course) - "appraisal-correcting adaptation" (an adaptation of normative parameters of the level of assimilation of materials, taking into account the results achieved by students). The introduction of the proposed three-stage system makes it possible to implement in individual educational trajectories and to form for each student a personal space of mathematical educational content that adapts to its level of mastering the material, which helps to improve the quality of instruction in mathematical disciplines. An approbation of the proposed algorithms was carried out in the adaptive e-course in discrete mathematics, implemented at Siberian Federal University in Russia.


Two frequent problems in content-based image retrieval systems are the poor quality of the results, due to the semantic gap, and the slowness of the image retrieval. For controlling these problems when human face image sets are considered, a new approach, called the MIFLIR system, is presented in this paper. This approach allows reducing the semantic gap by using fuzzy predicates during the indexing and the retrieval of images. In addition to this, our system innovates by using a metric indexing method to accelerate perceptibly the retrieval of images. Experimental results show that the MIFLIR system reduces noticeably the total time for performing fuzzy queries, when compared to a similar system which uses sequential scan search method.


Abstract Twenty years after the Mozambican war ended, a return to arms from 2013 by the opposition movement Renamo served to revitalize support for the party in the 2014 election, and put pressure on the Frelimo government to consider demands for constitutional change. Building on existing research on post-war politics and on recent economic change, this article addresses the question of how Renamo obtained civilians' approval for renewed armed action in the south of Sofala province, the region where conflict broke out in 2013. I argue that popular legitimacy for Renamo's challenge to the state is constituted in a narrative about Renamo that is congruent both with present-day grievances against the state and with understandings of local history dating to the anticolonial struggle that challenge the nationalist history on which Frelimo hegemony rests. Renamo has adapted this narrative in such a way as to claim a historic role for itself in defending the interests of central and northern Mozambique and in struggling for an inclusive and democratic state. In this way, Renamo has gained support for its renewed armed actions, not only among those politicized by Renamo in the earlier war but more broadly among civilians in the region.


This study intends to investigate the effect of the factors, namely price, reliability, responsiveness, assurance, and empathy on customer satisfaction towards the e-commerce delivery services. A total of 311 respondents were recruited using convenience sampling to participate in this study. All the measurements of constructs were adapted from previous studies. The reliability of the variables was assessed using the Cronbach's alpha and multiple regression analysis was performed to examine the effect of all the factors in the research model on customer satisfaction. The findings have shown that all the variables, namely price, reliability, assurance, and empathy have a positive influence on customer satisfaction with e-commerce delivery services. Responsiveness, however, has no influence on customer satisfaction. Assurance was revealed to be the strongest predictor of customer satisfaction. The second strongest factor was empathy. Understanding factors influencing the delivery services of e-commerce is essential as it is able to provide useful information for the delivery service company which will help them to enhance the quality of their services. The findings of this study would provide an insight of the customer satisfaction towards the delivery services of e-commerce during the COVID-19 from Malaysian's perspective.


People in rural communities are often hit disproportionately hard by natural hazards, largely because of in-equitable and inflexible risk reduction policies. But there are ways to change that.


This study proposes a framework for analyzing and understanding the relationship between ethical leadership and the management of workforce diversity. Using meta-synthesis as a methodological approach, the study examines the current research stream in workforce and workplace diversity. Second, the concept of ethical leadership is examined, including the conditions for its applicability and possibility in creating leader-follower relationship. It is argued here that our understanding of diversity and all of its ramifications are products of our ethical and cultural conditioning. A review of the ontological nature of ethical leadership indicates how organizational leaders function as role models and how members of the organization identify themselves with the organization ideal as embodied in the leader's ideal. Further, we explain how the actions of organizational leaders as parental figures and role models are capable of altering followers' perception of their individualities and their realities. We argue that organizational leaders can and should use their power of influence (as role models) to make their followers recognize the inherent advantages and challenges of a diverse workforce and workplace. We point out that the inability of our leaders to manage the diversity in our society and institutions poses a serious threat to the nation's security. On this basis, we suggest that ethical leadership seems to be an appropriate form of leadership behavior for managing a diverse workforce capable of achieving the goals of an organization. Finally, five ethical leadership approaches for creating and sustaining effective management of workforce diversity are suggested.
Keywords: Workforce Diversity, Ethical Leadership, Ethical Climate, Cultural Orientations.


L islet autografts restore diabetic metabolism to normal in the short term. Complications of diabetes appear only after a significant duration of disease process. An assessment of long-term function of grafts needs to be made before allograft experiments are entertained. Twelve dogs were made diabetic by total pancreatectomy. Seven dogs received 50% of a graft prepared by an established technique (group 1). Five dogs received 33% of a graft prepared by a method previously shown to be initially effective (group 2) (1). Tissue was grafted into the splenic pulp in all animals. At 1, 3, 6,12,18,24, and 30 mo, euglycemic animals were assessed by intravenous glucose tolerance test so glucose clearance, insulin, lactate, pyruvate, alanine, free fatty acids, glycerol, 3-hydroxybutyrate, and glucagon responses could be determined. Splenectomy was performed on one animal in each group at 2 mo to confirm graft dependence. All animals in group 1 became diabetic by 8 mo, with fasting hyperglycemia occurring at 2, 4, 4, 7, 8, and 8 mo, respectively. No animals in group 2 became spontaneously diabetic. Abnormalities in fat metabolism were noted up to 3 mo but had normalized by 6 mo, and metabolic profiles were normal up to 30 mo. Histology of the spleens confirmed the presence of the three islet cell types. Delayed graft failure occurs with the established technique of graft preparation (group 1), but long-term function can be achieved with the group 2 method. In addition, metabolic control remains normal for up to 30 mo.

Though it is widely accepted that French do not signal focus through pitch accent assignment, the relationship between information structure and prosody is not well understood in this language. Among the strategies available for French speakers, prosodic phrasing has been recently put forward as playing a crucial role in focus marking. In this paper, we examined the effect of contrastive focus on the prosodic boundary strength located at the right edge of focus regions in semi-spontaneous speech. Specifically, we investigated the acoustic properties (preboundary lengthening and tonal cues) of final syllables associated to three levels of prosodic boundaries (i.e. Accentual Phrase, intermediate phrase and Intonation Phrase) that could be either contained within all focus utterances or associated with the right edge of narrow foci. Results showed that, by the way of narrow focus, an Accentual Phrase boundary was replaced by an intermediate phrase boundary while intermediate and intonation phrase boundaries were not affected by focus manipulation. The findings provide quantitative support for the view that contrastive focus is associated with a minimum prosodic size in French.


PURPOSE: A resource allocation mapping method, a CSRS(Cell Specific Reference Signal) transmission device, and a method thereof are provided to simply produce a sub-carrier index. CONSTITUTION: A first and a second output part(110,120) produce a sub-carrier index so that the same sub-carrier index is allocated in a base station. The base station has a same remainder which a base station index value compartmentalizing a plurality of base stations is divided by a predetermined constant. A transmission part(200) maps the resource allocation of a CSRS according to each base station by using the calculated sub-carrier index. The transmission part transmits the CSRS.


The current crisis fosters a renewed interest in innovation, a way to experiment a new growth regime. In this context social innovation appears to be the new solution, likely to promote not only growth, but a form of fairer sharing and even to redefine social policies. It is often presented as a way to combine the desire for change and a form of guarantee of fairness and social justice that would build on creativity of actors and particularly private actors. But its definition remains unclear. We present three main approaches to social innovation, then we identify three dominant issues: the nature of innovation, the meaning and scope of the "social" dimension of innovation, and finally, characteristics of entrepreneurship (individual or collective), in connection with the form of governance and the participation of a number of stakeholders.

Objective
To investigate the clinical features of varicella and the prognosis in pregnant women and their newborns.

Methods
Clinical data of pregnant women with varicella zoster virus (VZV) infection (n=25) and their newborns hospitalized in Beijing Ditan Hospital from 1st Jan. 2008 to 31st Dec. 2014 were retrospectively analyzed and randomly compared to non-pregnant women with VZV infection (n=50). Clinical features and prognosis of varicella in pregnant women and their infants were analyzed. Chi-square test was used for categorical data and t test was used for quantitative data.

Results
Time to rash scab of varicella in pregnant women was longer than non-pregnant women ([10.1±2.1] d vs [5.6±1.4] d, t=10.941, P<0.05). The rate of bacterial infection in pregnant women was higher than non-pregnant varicella women (72.0%[18/25] vs 32.0%[16/50], χ2=10.761, P<0.05), with statistical significance. Among 25 cases of varicella pregnant women, the pregnancy complications were observed in 3 cases of diabetes, 2 cases of premature rupture of membranes, 5 cases of anemia and 1 case of oligoamnios. Seven cases out of 25 pregnant women underwent parturition during fever and varicella period, and 3 cases (12.0%) were complicated with intrapartum hemorrhage. Twenty five varicella pregnant women were all cured after antiviral and supportive treatment and gave birth to their babies, with no abortion, stillbirth or birth defects. No congenital varicella was observed in newborns. Of the 25 infants, 4 developed (16.0%) varicella within 2 weeks after birth and they were all born from mothers who developed varicella around delivery time. The clinical features of neonatal varicella presented with classic rash with no fever. The time to rash scab was longer (11.0±2.1) d and antibody test for VZV was negative. All neonates were cured after antiviral and immunoglobulin treatment.

Conclusions
Longer duration of skin rash scab and higher rate of bacterial infections are the features of varicella in pregnant women. Intrapartum hemorrhage occurrs more commonly in pregnant women with varicella onset around delivery time. Varicella occurring during mid-pregnancy may not increase the risk of neonatal birth defects after treatment. The newborns whose mothers with varicella onset during perinatal time especially around delivery time may suffer from varicella. The prognosis of neonatal period varicella is good after treatment.

Special education demands an awful price from those who are its practitioners. We not only deal with events and conditions which extract a great deal of physical and intellectual energy, but we are frequently confused by the many, often conflicting roles we are expected to fill. The constant changing of hats, as from counselor to teacher to consultant to administrator to advocate to ... well, you get the idea ... can cause a great deal of confusion, stress, and occasionally, burnout. When the situation looks just about hopeless, we can sometimes find a bit of professional refreshment if we are able to step back and look at exceptional children in a different way from the usual, perhaps with the help of some scholar who has a fresh point of view. Lauren Carlile Bradway is such a scholar, and her book provides, at the very least, a different angle from which to view handicapping conditions. At best, A Systems Approach to Handicapped Children, could be the basis for a new set of theoretical constructs upon which to base an approach to assessment and intervention. General Systems Theory has been applied in psychiatry for some 30-odd years, and the application was actually formalized by Dr. William Gray in 1969. In this book Dr. Bradway has at the same time extended and more sharply focused this humanistic application to include handicapped children. The basis for the book is the picture of the child, himself a living system," ... ecologically suspended in multiple systems ... " (p. 9). Each living system has both subsystems (parts) and suprasystems, or wholes. In Bradway's structure, subsystems and suprasystems are interdependent, each depending in some way upon the other, for its continuing existence. The handicapped child must function as a pan of one or more suprasystems, while both influencing and being influenced by each. In tum, the child, as a suprasystem, both influences and is influenced by the other internal and external systems that define his/her existence. The author employs an analogy using the human bean and the body in which it resides. While the body cannot survive without the hean (which is a living system itself), the hean cannot continue to function without the suppon it receives from the body, which is the suprasystem. Bradway conceives the child as pan of a suprasystem which consists of three primary systems: the biological, which is contained entirely within the physical body of the child; the psychological, which is bounded by the personality; and the social, whose unit of concern is the role, and which is likened to the ripples made when a pebble is dropped in a pond, making ever-widening circles. Each of the social structures in the child's external word is a pan of the total social system. In Bradway's conceptualization, each of the major systems may be subject to stress, resulting in a disturbance which in turn can produce a malfunction or distonion of the interrelationships between the child and his/her ecological system. Since development and learning are strongly influenced by these interrelationships, assessment of the status of the primary systems and a description of their functioning become central to development of appropriate treatment plans. Bradway has clearly illustrated, through the use of case studies, how the model can be applied in a variety of types of child problems. The case studies, by engaging the reader in applications of the model, help to prevent what could be a very dull bit of business. Just enough basic child development theory has been included to keep the relatively naive reader in the game without boring the more sophisticated professional. One helpful device employed throughout the book Is the presentation of the "red flags" in a child's history which signal the need for specified types of detailed assessment. Bradway also consistently has employed a dear and simple structure for summarizing each child's evaluation and treatment plan, as follows: Primary System Disturbance-Identification of the primary system in which the disturbance is noted, Template/Environment-Summary of the influence on the child's condition by the com bination of inate characteristics of the child and the influence of the child's interaction with the environment, Learning Style-Identification of the child's preferred Input channel, if any, and a 'lreatment Plan-Identification of the primary system(s) on which the treatment plan will focus, and a very brief description of the type of activity to be employed.


Antonín Dvořák composed the String Quartet in F major (op. 96, the 'American') in June 1893 while visiting the town of Spillville, Iowa, USA. Based on accounts from Dvořák's secretary Josef Kovařík, portions of the quartet's Scherzo movement were inspired by birdsong Dvořák heard in Spillville. Kovařík's account included both Dvořák's visual description of the bird that inspired him and a transcribed fragment of the birdsong Dvořák reportedly used. In 1954, Clapham identified the bird as a scarlet tanager (Piranga olivacea), based mainly on the visual description. This widely accepted identification was questionable because of the poor match of the tanager's song to musical material in the Scherzo. In 2016, Floyd proposed the red-eyed vireo (Vireo olivaceus) as Dvořák's inspiration, based on song rather than appearance. The vireo's song is clearly identifiable in the Scherzo as well in the birdsong fragment recorded by Kovařík. The mismatch between the visual description and the transcribed song fragment could have occurred when Dvořák heard and recorded the persistent singing of a cryptic red-eyed vireo, but misidentified the song's source when he caught sight of a brightly coloured tanager. Correct identification of the birdsong changes the interpretation of the movement. Previously, birdsong has been considered the source of a short secondary motif. But red-eyed vireo songs are highly variable, and a slight variation of Kovařík's song fragment could be the basis of the main theme of the Scherzo. Therefore, Dvořák may have used American birdsong in the movement considerably more than previously appreciated.


The Adjective Generation Technique was used to evaluate and compare progressive relaxation training and practice sessions for one female client. The subject acquired the relaxation skills and maintained them at 3 mo. follow-up. Changes in the referral complaint were also reported. The clinical advantages of using the technique over traditional anxiety scales were described.


Background and Objectives: Mass screening for parvovirus B19 (B19) by receptor–mediated hemagglutination assay (RHA) may be inadequate to eliminate the virus from plasma pools. We characterized B19 carriers detected in blood donor screening by RHA to explain why some carriers were not detected by RHA. Materials and Methods: Donor plasma was screened for B19 by RHA, B19 DNA by nested polymerase chain reaction (PCR) assay, and anti–B19 by enzyme immunoassay. Results: B19 DNA–positive specimens (n = 73) screened from 456,665 donors were divided into group A (n = 41) with high DNA and high RHA titers, group B (n = 16) with low DNA and low RHA titers, and group C (n = 16) RHA–negative. Most (37/41) of the group A samples were without anti–B19, while most (15/16) of the group B samples were positive for anti–B19. Group C specimens were screened by PCR from 3,042 random RHA–negative specimens. Analysis of samples from early infections revealed that the viremic period, corresponding to group A, lasted only 8–10 days after infection. The RHA reactivity fell rapidly with the appearance of anti–B19 and disappeared 28–30 days after infection, thus corresponding to group B. The RHA reactions of group B specimens were often unstable, probably because of the formation of immune complexes. The B19 DNA–positive, RHA–negative state lasted for several months, which corresponded to group C. Conclusion: Only group A specimens are reliably eliminated in donor screening by RHA. Therefore, although donors with high B19 DNA could be screened out by testing for B19 by the RHA, most B19 carriers, with low B19 DNA and RHA–negative, will not be eliminated.


Abstract : Congress enacted the Chief Financial Officers (CFO) Act in November 1990 to improve financial management in the Federal Government. It requires 23 federal agencies, including DOD, to submit annual financial statements to the Office of Management and Budget. The Secretary of Defense, William Perry, testified before Congress in 1995 that, we need to reform our financial management. It is a mess, and it is costing us money we desperately need." The military services waste billions of dollars each year because of poor financial management practices. DOD is taking a centralized, top-down, and long-term approach to meet the requirements of the CFO Act. It's not working. This approach doesn't include the leaders in the field in the solution. Therefore, the operators stationed throughout the world are unaware of the massive changes that need to occur and largely uniformed of the readiness benefits and savings that could arise. We must improve our financial management practices. We can't afford to waste any of our defense dollars as resources continue to decline. The process of preparing auditable financial statements will provide our leaders with more reliable and accurate resource information which will improve their decisions and will lead to increased levels of readiness by the more efficient and effective use of federal funds.


DURING the period that civilized man has held dominion over the Southwest, dwarf forests of invading shrubs and small trees have insidiously taken possession of millions of acres of the remaining uncultivated grassland. Acreage of mesquite alone in Texas and Oklahoma is greater than the area of the state of Wyoming. Many have been deceived into believing that trees and brush moved in like a plague or passover and killed out the grass (13), but that viewpoint is slowly dying out as the real cause of grass destruction and brush invasion is being understood. The primeval grasslands that were free of brush stayed free of brush because the dominating grasses had the strength to hold the land against invaders. When livestock crowded the ranges and ate down the best grasses first, the lower class plants which succeeded them were not strong enough to hold off the aggressive brush and trees. The original native grasses grow with trees and brush when correct grazing is practiced. On heavily grazed brush ranges, the only traces of original grasses are usually found within the thorny basal branches of brush, which guard the grasses against grazing animals. One Texas ranchman says that a sure clue to range improvement is when grazing lightens up so the good grasses can "come out of the bushes into the open". Cedar and other evergreen plants with dense horizontal spreading branches shade the ground so completely that they afford little or no sanctuary to grasses. While the good grasses may flourish in brush land, they can never reach excellent condition until the trees or shrubs are killed out. Successful removal and control of dense stands of undesirable woody vegetation gives farmers and stockmen a major opportunity to conserve water and to increase forage production. In areas where there are dense stands of useless woody vegetation more water is lost by transpiration through the leaves each year than runs off down the draws, streams and rivers (1). For the most part woody plants on the range are water hogs. Some, like mesquite, require two to four times more water to grow a pound of dry leaves than do grasses.

Of the vast quantity of fine relief which decorates the temple of Hatshepsut at D£r el-Bahri, no single composition has attracted more scholarly attention than the famous scenes representing the commercial expedition to the land of Punt in the Queen's ninth year. As well as being a historical document of the first importance, the Punt relief of Hatshepsut provides us with a remarkable example of an artistic arrangement which resembles a "landscape with figures" in the modern sense more nearly perhaps than any similar work produced by an Egyptian artist. Unfortunately, the interest and value of the scene have been much diminished by the damage the walls have suffered through natural accident and by the hands of vandals. By a happy chance, one of the missing portions has recently come to light in Cairo and now rests with its companion pieces in the Egyptian Museum. Early in October of 196 1 the writer had occasion to visit the home of a resident of Cairo whose father had collected a few fragments of ancient relief. His heirs were anxious to dispose of objects of so little interest to them, and wished to have them inspected by an Egyptologist before offering them for sale to one of the dealers in antiquities. Most of the pieces were of little or no value either historically or artistically, but one of them, a slab of fine white limestone broken into several fragments, was immediately recognizable as a missing part of the Hatshepsut Punt relief, and the writer accordingly made arrangements with the owners for its purchase by the American Research Center for presentation to the Egyptian Museum. It was felt that a fragment of a famous and beautiful national monument should not be permitted to leave the country, as certainly would have been its fate if it had fallen into the hands of a dealer, and since the adjoining pieces of the composition had been removed for safekeeping to the Museum, the new slab could fittingly be placed beside them. Accordingly on the tenth of January the relief was formally donated to H. E. Dr. Sarwat Okasha, Minister of Culture and National Guidance, at the Abdin Palace. Later the same day it was removed to the Chemical Laboratory of the Egyptian Museum, where it was treated and repaired, the several fragments being cemented together and the back strengthened with plaster. Before describing the new slab, it seems in order to review briefly the previous publications of the great Punt relief. In 1877 tne French savant Auguste Mariette produced as one of the last major works of a long and fruitful life the first publication of the Der el-Bahri temple that attempted to be in any way comprehensive.1 An earlier work by Duemichen, Die Flotte einer dgyptischen Konigin, published in Leipzig in 1868, had dealt with the Punt reliefs at length, making a serious attempt to identify the wildlife represented and thus determine the locale of the country the Egyptians knew as Punt. In both of these publications the famous scenes are shown in a more complete state than they exhibit at a later date, and it would seem that it was about this time that some of the slabs of relief were stolen from the south wall of the Middle Colonnade. Indeed, it is more than likely that the appearance of the two publications, and the consequent increase in scholarly interest in the temple, were directly responsible for the plundering; it would not be the first time in archaeological history that scholarly notice of a monument drew the less disinterested attention of dealers and unscrupulous collectors. At any rate, the vandals who descended upon Der el-Bahri were obviously well aware of what portions of the much-admired relief would be most readily saleable, and they proceeded

The online monitoring device of power equipment can realize the real-time monitoring of the equipment, and the accuracy of its data will have a direct impact on the adjustment of the subsequent operation and maintenance strategy. Therefore, it is necessary to evaluate the usability of online monitoring devices. In this paper, a method of on-line monitoring device usability is proposed based on the transformer operation state. Based on the theory of signal decomposition, the systematic trend, random fluctuation and large jump of on-line data are separated from the original data. The error of on-line monitoring data is creatively divided into three parts: huge error, random error and systematic error. The errors are quantized and evaluated. Finally, the usability of on-line transformer monitoring device is obtained by synthesizing three kinds of errors evaluation. This method has a good effect in evaluating the overall or single usability of the on-line monitoring devices.

The results of calculations demonstrate a high demand for male graduates of degree programs in the field of computer science and female graduates in the field of medicine. Conclusions The professional competences formed by Russian educational programs should better meet urgent and future needs of the Russian labor market.


Concurrent and spray-tower studies have been accomplished that illustrate the effects of ultrasonic insonation on transfer rates in liquid-liquid extraction. Stage efficiencies and over-all transfer rates in the system toluene-methyl alcohol-water were determined with and without insonation of the system at frequencies of 40 and 800 kc.

Insonation was shown to have a positive effect on mass transfer in both concurrent and spray-tower operations. Insonation of the system provides for increased interfacial area between the two phases, removal of relatively stagnant liquid layers at the interface, and increased circulation currents within a single liquid phase. Low-frequency insonation favors local agitation and mixing of the phases, and high-frequency insonation favors induced circulation currents.


Introduction Persistent organic pollutants (POPs) are a heterogeneous group of ubiquitous environmental pollutants with a high persistence accumulating in the food chain. Despite external background exposures being relatively low, the long biological half-lives of these compounds in humans lead to considerable accumulation, with measurable levels of internal exposure in the general population. With respect to possible effects, fetal exposure may be especially critical (expected highest susceptibility), and postnatal exposure from breastfeeding, in the case of a long duration, is expected to be the highest exposure period over a lifetime. In this context, two groups of POPs are in the focus of scientific and public concern, namely dioxins and perand polyfluorinated alkyl substances (PFAS). One possible effect of exposure is an impact on the male reproductive system in fetal life and/or early childhood resulting in reduced semen quality in adulthood. In the case of dioxins, evidence comes not only from animal experiments,1,2 but also from high-dose exposure to tetrachlorodibenzop-dioxin (TCDD) following the Seveso accident in 1976.3 The European Food Safety Authority (EFSA) used data from a study of high ambient exposure in a Russian industrial city4 to lower the tolerable weekly intake (TWI) in 2018.1 Investigations into the effect of early PFAS exposure on male semen quality in laboratory animals are missing, but epidemiological support comes from a study of 864 participants,5 which focused on the exposure to PFAS in early pregnancy only. With respect to the latter study, the question of the correlation of dioxins and PFAS was raised in a comment,6 showing data of dioxin international toxicity equivalents (I-TEq) and perfluorooctanoic acid (PFOA) in 11-month-old children predominantly breastfed for at least 4 months,7 with a Spearman's rank correlation coefficient of r=0:77. In their response,8 the authors argued that they expect low correlations of dioxins and PFAS with respect to prenatal exposure (i.e., concentrations in the mothers). Data on the correlations are available from our study,7 not only for the children,6 but also for the mothers, the latter of which are presented in this article.


The geometry of the trilobite visual surface is important in studies of trilobite taxonomy, paleoecology, and evolution. Unfortunately, methods for measuring visual surface features have been slow and laborious. The authors have built an apparatus which allows rapid, reliable measurement of angular relationships on the trilobite cephalon. A specimen is mounted on a set of turntables rotated by steeper motors driven by impulses from a computer terminal. As the turntables are rotated, their angular displacements from zero are automatically recorded to a repeatable accuracy of less than half a degree. Thus the angular positions of lens axes, spines, glabella, and other important features can be recorded directly into the computer for further processing and graphics display. The authors apparatus was designed to study the eyes of phacopid-trilobites, for two reasons. First, the Phacops rana group of trilobites is one of the type examples of punctuated speciation. Second, it has been suggested that phacopids had stereoscopic vision in each eye. The new apparatus will allow rapid and accurate study of suites of specimens, in order to test these hypotheses. Their new apparatus, essentially a motorized goniometer, could be used or modified to work with any specimens in which rapid goniometric measurements more » are useful. Such applications could include routine morphometric studies of molluscan or brachiopod shells or echinoderm tests, as well as specific projects dealing with spines, pores, plates, or septa in a wide variety of fossil invertebrates. « less


ABSTRACT Arabic sources recall the tenth and early eleventh centuries as the time when Andalusian armies achieved their greatest military triumphs over the Christian kingdoms and counties of northern Iberia. Some of those victories were truly spectacular and their like would never happen again. However, this view is also the result of the concealment, justification, and minimisation of defeats, as well as of the exaggeration of the successes achieved. This follows from a critical reading of Muslim chronicles and from the study of the data provided by Latin sources. The present article discusses some of the aforementioned practices of chroniclers and analyses whether the image offered by Arab compilers overstated the true military potential of the Umayyad Andalusian Caliphate. It concludes that caliphal armies were already showing some alarming signs of weakness during this period.

Should a defect of the hard disk drive or critical error of the OS program occur, the OS program may need be reinstalled or a recovery program may be run to recover the initial states of the OS program and the application programs. The product key stored in the CMOS RAM will be used during the recovery or re-install process, so that the user does not have to manually input the product key again.


Among the Christian inscriptions of medieval Nubia are a dozen which contain, along with the familiar month and day in the Egyptian calendar, a date by the moon, ae^r/vr) (in various spellings) or OTNN&. (the Old Nubian word for moon) (), followed by a number. It has generally been agreed that these indications refer to the lunar months. Now most of these insciiptions have also a date to the Era of the Martyrs (i.e. from Diocletian, year 1 = 284/5) (), and a few have also the indiction or the day of the week. A few, however, have no such year date, or the year numerals are lost or damaged. In such cases, modern scholars have sought to use the lunar date, in combination with the other data like month and day, day of the week, and indiction, to find a date which uniquely fits the available indications in combination. For example, V. Grumel sought to date Lef. 663 (no. 10 in the table below) to A.D. 943 or 1122 on the basis of a coincidence of Phamenoth 11, Tuesday, and the 20th day of the moon (*). As we pointed out before (), Grumel failed to recognize that this text also has a date by the fifth indiction, and neither of these years is compatible with a fifth indictibn. We went on to remark, « of Grumel's attempts ... to use [lunar dates] to date otherwise undatable texts, three fail completely to provide any solution, and two others succeed only by circular reasoning or choosing a calendar to fit the answer (•). » We have attempted to apply an


It is known that conventional chemotherapy has average success rate of less than 25%, which seems to suggest that we need a better therapy for cancer. Chemotherapy and radiation employ non-specific toxic effects to inhibit the proliferation of both normal and tumor cells. In this regard, specific low frequency EMT has been reported to restore the homeostatic function of genes involved with controlling cell growth. Here I discuss possibility of a novel approach of cancer treatment using various applications of electromagnetic frequency.


Combining with the engineering fact,the paper analyzes some listed treatment methods by comparing with the advanced experience of the sludge treatment at home and abroad,and points out the optimized scheme for the sludge treatment and the application of the urban sewage treatment plant by comparing their advantages and disadvantages,so as to reduce the environment pollution caused by the sludge.


In this paper zone reactive power controller is presented. Power network is naturally divided into voltage areas which are semi-independent or, at least, have no significant impact on neighbouring areas. Natural voltage areas, zones, represent the impact range of control actions performed in a certain zone. Control actions influence is small in neighbouring zones. Each zone is characterized by the pilot node (PN) voltage value (or profile) which is maintained by coordinated action on control equipment and generators in the zone. Additional zone reactive power controller is introduced which reduces reactive power exchange with neighbouring zones if there is sufficient reactive power and voltage reserve in order to minimize losses due to reactive power flows. Simulations are performed to demonstrate the effectiveness of the solution as well as advantages and disadvantages.


This paper focuses on the determination of the characteristics of refusals in low voltage electrical distribution systems. In order to solve this problem, the phenomena of occurrence of refusals in low-voltage electrical distribution systems, conditioned by different influencing factors, processed and mathematically modelled. The main results of the research consist in establishing the static characteristics of the refusals, the mathematical models that determine the occurrence of the cause phenomena and the parameters that characterize the distributions of the refusals, depending on the occurrence per system, depending on the occurrence per season, depending of interruptions duration and the number of affected consumers. The significance of the results obtained consists in solving a number of problems faced by the operating services of electrical distribution systems, concerning the assurance of reliability of operation, providing the possibility of forecasting and preventing the occurrence of the phenomena of occurrence of refusals, which enable the justified planning of prophylactic measures and ensuring the reliability level.


The increasing number of Covid-19 patients causes an increase in the need for care for Covid-19 patients which also increases. The need for drugs, treatment rooms, medical personnel available at the hospital is important information that must be updated because an increase in Covid-19 patients hospitalized will reduce the availability of the number of health facilities available so that the government can take strategic actions to manage all resources necessary health facilities. The problem found was that information on health facilities resources such as treatment rooms, medicine, medical equipment, Covid-19 patient information and regional government data were not well integrated, making it difficult to update information based on changes in data in the field. The purpose of this research is to build a geographical model of the COVID-19 patient information system that integrates information resources on health facilities and regional areas. The GIS concept is used in research outputs to facilitate management in obtaining spatial information for policy making and strategic decisions related to handling Covid-19 patients. The result of this research is a GIS model for Covid-19 patients.


This paper dealt with key functions of Administrative ethics in a democratic society. In order to discuss the nature of administrative and professional ethics in a democratic society, four paradigmatic values of American public administration are sketched in this paper. From the very beginning of its study, public administration has concentrated its effort to discover how government can do its proper thing with economy and efficiency. After the initial establishment of public administration as an academic discipline, the objectives of economy and efficiency are included in rationality which becomes utmost value of administrative science. On the other hand, democracy as an ideology of public administration took increasingly attention an alternative ideology of bureaucracy, while behavioralism emphasized rationality in administration and policy making. Finally, in the similar context, social equity added to the existing values as a norm of public administration. Public administration pursued basically those four value paradigms : namely economy and efficiency, rationality and social equity. They worked together as instrumental values or evaluation criteria on the performance of public administration. It is suggested that it is time for public administration to synthesize those four values into two, i.e., rationality and democracy. For economy and efficiency could be pursued in the context of rationality and social equity could be included in democracy. Rationality and democracy are interdependent rather than contradict each other in terms of administrative ideology. Further research direction, thereof, is to make democracy expand the sphere of rationality, while contracting the realm of irrationality, and to make rationality enlarge the democratic area, while limiting the undemocratic realm in public administration. Based on this analysis, the paper examines the contents and functions of Korean public ethical codes to control the behavior of Korean civil servants. They are Korean civil servant law, public servant ethical code, oath of Korean public servants, and ethical constitution of Korean civil servants. The discussion is also made to sketch the problem areas of current ethical codes applicable to Korean civil servants and the methods to alleviate shortcoming of ethical codes available for Korean civil servants. In the conclusion of the paper, several proposals are made to cover the proper roles and functions of administrative ethics in democratizing society of Korea.


Abstract: Authentication will perform a vital role in the computer based communication. The usual approach for the attendance is the professor calls the student name and records the attendance. This leads to the wastage of time for the parents to check the regular presence of the students to the college and also college administrative people. To avoid this we are going to use the automatic system which is based on face recognition technique. This project informing the parent about the presence of the student for the college through GSM SMS will give the automatic solution. In this GSM based automatic attendance system we are going to use the webcam, zigbee, GSM. The working of this project is identifying the face and marks the attendance for the corresponding person as in the database.


In some remote areas,there still exists the uxorilocal custom among the Buyis with its rich cultural connotations.It is some remains of the Buyi matriarchal society and a transitional form towards the virilocal custom.It also embodies the Buyi's attitude towards sex and their traditional ethics that shows their good qualities of maintaining the interests for all and the whole family and mutual trust.


A eutactic star on an integral lattice is called extremal if it induces a holomorphic Jacobi form of lattice index and singular weight via the theta block. The famous Macdonald identities imply that root systems are extremal as eutactic stars. In this paper we prove that every extremal eutactic star arises as a root system. This answers a question posed by Skoruppa.


This paper has presented high modulated soliton power transmission interaction with optical fiber and optical wireless communication channels at flow rate of 40 Gbps and 20 km link range. The proposed modulation schemes are continuous phase frequency shift keying (CPFSK), Quadrature amplitude modulation (QAM), differential phase shift keying (DPSK), frequency shift keying (FSK), pulse amplitude modulation (PAM), minimum shift keying (MSK), and optical quadrature phase shift keying (OQPSK). CPFSK has presented better performance than other proposed modulation schemes for both optical fiber and optical wireless communication channels. The enhancement of optical signal/noise ratio at fiber/wireless channel, received electrical power and signal/noise ratio at optical receiver with increase of bits per symbol for different proposed modulation schemes except for CPFSK scheme. Therefore it is evident that CPFSK modulation scheme is more efficient and better performance than other modulation schemes for different communication channels. The obtained results are simulated with optisystem program version 13.


In order to improve the conversion efficiency of SCR system,a compact DOC-mixer-SCR aftertreatment system was put forward and three kinds of aftertreatment models were built.With the aid of computational fluid dynamic(CFD)coupled with chemical reaction dynamics,a 3Dmodel of SCR-NOxcatalytic converter was established.With the model,the whole aftertreatment process including the injection of urea aqueous solution,the evaporation and thermal decomposition of droplet and NOxcatalytic reaction was simulated and the distribution law of turbulent kinetic energy field,velocity field and concentration field was acquired.In addition,the simulated results were compared with those of traditional aftertreatment system.The research results provide the reference for the design of aftertreatment system.


In a study of 3,361 occupant victims of motor vehicle accidents in Southeastern Ontario, the demand for medical services and the rehabilitation requirements were measured. Comparison of the requirements for medical services and rehabilitation time by restrained and not-restrained occupant victims identifies that an impressive proportion of them is reducible by seat belt use.

Since proposed, LDA have been successfully used in modeling text documents. So far, words are the common features to induce latent topic, which are later used in document representation. Observation on documents indicates that the polysemous words can make the latent topics less discriminative, resulting in less accurate document representation. We thus argue that the semantically deterministic word senses can improve quality of the latent topics. In this work, we proposes a series of word sense aware LDA models which use word sense as an extra latent variable in topic induction. Preliminary experiments on benchmark datasets show that word sense can indeed improve topic modeling.


Abstract The manufacturing process of cold rolling line in steel industry is often complicated due to its long production flow, a large number of product categories and machines. The static production plans usually have to be repeatedly assigned when some unexpected circumstances occur, for example machine malfunction and material delay. In this study, a distributed dynamic scheduling model based on multi-agent is established for solving the rescheduling problem of cold rolling line, in which a dynamic reconfiguration of the production flow is further studied to realize the balance of machine yields ability and load. For solving the established model, an ant colony optimization based on dynamic constraints is proposed. The practical experiments with real data of Shanghai Baosteel Co. Ltd demonstrate that the proposed method is effective to the production rescheduling of cold rolling line.


Pierre Bourdieu tries to surmount binary conflicts such as structure-agency,system-actor,subjective-objective.In this article,the author argues that Pierre Bourdieu' the theory of practice emphasizes the process and the latent logic of practice,and reflection is one indispensable part of his theory of practice.Only by considering both points can Pierre Bourdieu' theory of practice be understood well.Pierre Bourdieu' theory of practice not only has very important academic value but also great revelation to sociology.First,Bourdieu's ideas and reflection on ontology,epistemology and methodology are helpful to increase the scientific property of sociology.Second,Bourdieu's argument that sociology is also political science is very valuable to understand the properties of sociology and will promote the development of sociology.Third,he provides the enlighten thoughts and concepts for the efforts of sociological indigenization.


We have demonstrated a novel scheme for distributed optical fiber sensing based on the use of a dual frequency comb, which enables the development of a high-resolution (in the cm range) distributed sensor with significantly relaxed electronic requirements compared with previous schemes. This approach offers a promising solution for real time structure monitoring in a variety of fields, including transportation, manufacturing or mechatronics. In this work, we review the principle of operation of the technique, recent advances to improve its performance and different experimental tests.


Domain adaptation is a well-studied field of research that aims at adapting machine learning models trained on specific source domains into different target domains. However, the case of multi-classifier systems is relatively less studied particularly in terms of experimentation. In this study, we investigate the impact of combining classifiers trained on different sources by simple averaging techniques, namely, arithmetic mean and normalized geometric mean, followed by a rich set of experiments to examine to what extent accuracies obtained in target domains benefit specifically from bagging. In this respect, we also propose a distance- based scheme to find a proper value for the number of weak classifiers to train. Our experiments have been conducted on the conventional Amazon product review dataset for a binary sentiment classification task. As a result, applying ensemble methods on multi-source datasets empirically stands out as a simple yet effective strategy to obtain robust results in case of domain shift. Thus, it is recommended as a strong baseline for evaluating more sophisticated domain adaptation algorithms. Provided that appropriate values are selected for the number of weak classifiers as well as for sample size, bagging-based models are resistant to domain shift and able to perform as accurately as in-domain classifiers.


We developed a multi-probe atomic force microscope (AFM) having two AFM cantilevers independently controlled using the optical beam deflection method. We succeeded in simultaneously obtaining images with two independent probes by frequency modulation (FM) detection method. To evaluate the distance between the AFM tips of the cantilevers, we used a new the address-patterned sample, which was also developed for this study. The images obtained show that the distance between the probes was 2 µm. The development of the multi-probe AFM opens a wide variety of applications in the present nanoscience and engineering field.


Character and Citizenship Education and the Development of Moral Motivation Presenters: Wolfgang ALTHOF and Marvin W. BERKOWITZ, University of Missouri-St. Louis, USA Character and citizenship education must consider what psychologically comprises an individual who is both motivated and capable of acting in morally justifiable ways. In the case of character education, the focus is applicable to all spheres of life. In the case of civic or citizenship education, particularly in democratic societies, the focus is more on public and civil life and engagement. If schools are to nurture the moral proclivities and capabilities of their future adult citizens, then they must take seriously what is known about their developmental characteristics. In this presentation, we will examine some core models of both character and citizenship education, identifying their typical motivational strategies. We will contrast approaches that strongly emphasise intrinsic motivation (e.g., Marilyn Watson's concept of 'developmental discipline') with the common practice of 'motivating' students externally and in particular by rewards, as in the Positive Behavioral Intervention and Support (PBIS) approach.

Treatises on aesthetics and poetics first appeared in India around first century A.D. One of the earliest and most famous of such treatises is the Nātyaśāstra of Bharata. It is from this work that Indian aesthetics developed and reached its culmination in later centuries. Dhvanyāloka of Ānandavardhana, a pivotal work in the history of Indian poetics, with the Locana of Abhinavagupta, dominated traditional Indian theory on poetics and aesthetics. Abhinavagupta is the great devotee of the "Supreme Self" or Śiva. Though there are several works attributed to him, our chief concern is his commentary on Ānandavardhana'sDhvanyāloka. This work revolutionized Sanskrit literary theory by proposing that the main goal of good poetry is the evocation of a mood or "flavour" (rasa) and this process can be explained only by recognizing a semantic power beyond denotation and metaphor, namely, the power of suggestion or dhvani.


Anogenital warts (AGW) are caused by low-risk HPV types. Current therapies for AGW have notable side effects and high recurrence rates.1 As DNA viruses such as HPV rely on cellular K+ influx and Ionic contra-viral therapy (ICVT) comprised of digoxin and furosemide inhibits the K+ influx, ICVT might be a potential new treatment for AGW. Recently, a phase 2 randomized-controlled trial showed a reduction in size and viral load of HPV-induced cutaneous warts after 6 weeks of treatment with topical ICVT.

The purpose of this study was to assess the academic performance of Iowa Valley Community College District transfer students at the Iowa Regent institutions. The study analyzed the Regent first-term and cumulative GPA of IVCCD students who transferred to a Iowa State University, University of Northern Iowa, and the University of Iowa between 2000 and 2004. Four research questions guided the study: (1) What are the academic characteristics of IVCCD students who transferred to Regent institutions? (2) How did students perform at Regent institutions upon transfer? (3) Did transfer students experience a recovery in GPA at the time of baccalaureate degree attainment? (4) Are there significant differences in Regent first-term GPA based upon Regent institution, community college, sex, community college credits earned, degree vs. non-degree recipient, academic year of transfer, or academic discipline? Student-level data for 755 transfer students was obtained from Transfer Student Academic Performance reports provided by Offices of Admissions at ISU, UNI, and UI. Data analysis was accomplished through the use of demographic characteristics, means, standard deviations, and analysis of variance (ANOVA). Findings of the study indicated that students experienced transfer shock at the senior institution and obtained a Regent first-term GPA that was seven-tenths of a grade point less than their community college cumulative GPA. Students who persisted to graduation from the Regent institutions recovered 0.28 of a grade point from their Regent first-term GPA and achieved an overall GPA that was 0.24 lower than their community college cumulative GPA. ANOVA results revealed that students who transfer from MCC, who are female, and who complete degrees prior to transferring achieve a significantly higher Regent first-term GPA. In addition, students who enrolled in Education and Humanities achieved a higher Regent


Filum terminale ependymomas (FTE) commonly present insidiously and are uncommon among the geriatric population. We report here a rare case of spontaneous intratumoral haemorrhage from a FTE in an 80-year old patient. The initial symptomatology of acute back pain and lumbar radiculopathy mimicked the common emergency room presentation of acute lumbar disc herniation. The patient subsequently developed acute cauda equine syndrome necessitating urgent surgical intervention. We believe this is the first reported case of a contained intratumoral haemorrhage from a FTE in a patient of the geriatric age group. The case also illustrated the increasingly common encounter of the perioperative management of the nonreversible anticoagulant and antiplatelet agents in the context of emergency surgery.


The Hao-Cecilia image interpolation algorithm can eliminate the zigzagging artifacts better,but the shortcoming of the expansion ratio of 2 is inherent.In this paper,a novel linear image interpolation method is proposed to overcome it.The Euler equation of the variational regularizer is discretized using a Taylor expansion.The interpolation takes place along the direction of level line,which eliminates the zigzagging artifacts and suppresses blurring of edges.Numerical experiments demonstrate that the proposed algorithm can obtain better visual effect and higher Peak Signal Noise Ratio(PSNR).


The author considers the reflection of such a phenomenon as historical memory in the school textbook of history.Formation of the historical consciousness of youth occurs in the process of systematic study of history, therefore, the significant influence on historical memory is the knowledge gained in the general education school. The concept of a school textbook should reflect national priorities, be a means of integrating historical science and education, and have a patriotic orientation.
