Although themajor target cell for HIV in the body is the CD4 lymphocyte, uptake by and infection of other target cells suchmacrophages and dendritic cells also play a major role in pathogenesis. Macrophages are a major reservoir for HIV inmost lymphoid tissue in the untreated patient and remain themajor target cell inbrainwhether thesubject is treatedor not. Dendritic cells play a major role in transferring HIV efficiently to T cells particularly after viral entry through sexual transmission. Our work has focused on understandinghowHIVbinds to andenters these cells, trafficks through them and, during that time, alters their function to facilitate viral survival, replication and spread. Understanding of these processes is the foundation for a rational approach to the development of therapeutics (including microbicides) and vaccines.


Microemulsions formed with water, isopropyl myristate, PHS-PEO-PHS polymeric surfactant, and alkanediol have been investigated using small-angle X-ray scattering (SAXS) and conductivity at 25 °C. Isopropyl myristate has alow solubility in water; however, this molecule has some polar character because of its ester group. The conductivities of samples with some added NaCl(used here to increase the conductivity sensitivity) are low, but compared to the conductivity of water/alkanediol mixtures, the values are high for most of the samples. The X-ray scattering curves show a correlation peak if the water content is high enough. A two-phase model for the invariant calculation fits the experimental results reasonably well provided that the partition of the oil between the polar and nonpolar phases is taken into account. This partition can be obtained from the ternary water/isopropyl myristate/alkanediol system, which has some mutual-solubility regions. A hard-sphere model can be fitted to the SAXS scattering data. The volume fractions fitted from this model deviate from the volume fractions of the low-polarity phase, indicating that the structure of most of the samples is of the bicontinuous type.


Project-based service learning (PBSL) has become an emergent opportunity for engineering education. In this paper both curricular and co-curricular/extracurricular community service activities related to engineering will be described. In this field there are a number of national programs, for example EPICS, Engineers Without Borders and Engineers for a Sustainable World, as well as university-specific opportunities. Student interest and involvement in these programs has been explosive. Yet, partly due to the grassroots development of many of these programs, partly due to their rapid rise, there are scant findings on the impacts of these programs on engineering education. Preliminary findings suggest that students participating PBSL early in college are retained in engineering at higher levels, women participate in voluntary PBSL opportunities at higher levels than their representation in engineering overall, PBSL fulfills a variety of ABET learning outcomes, and PBSL enhances student preparation to practice engineering design. The community impacts of these projects are outside the scope of this paper. However, the impacts of PBSL on community partners are of equal importance to the educational outcomes and should be evaluated. This paper provides a broad review of existing PBSL programs, assessment methods used, and the impacts on students. A summit was held in early 2009 to leverage the collective expertise of the participants to identify desired outcome metrics, quality assessment methods, and key next steps needed in understanding the impacts of PBSL on engineering education. Those involved in PBSL seek guidance on how to better understand how these programs are affecting their students and institutions, and how to design the best experiences possible. The engineering professional community is interested in evidence indicating that graduates of these PBSL programs are achieving modern knowledge and skills. It may be that PBSL offers substantial promise for building the technological workforce needed by the nation. Project-Based Service Learning Project-based service learning is a form of active learning where students work on projects that benefit a real community or client while also providing a rich learning experience. Project-based learning (PBL) is learner focused. In contrast to traditional PBL where a project is developed by the instructor and the learning path is fairly predictable, PBSL adds the community as a full partner and the outcomes are less clear. William Oakes notes: "the facilitation of the [PBSL] experience is more dependent upon capitalizing on teachable moments and learning opportunities than with traditional PBL. The service-learning therefore requires a more flexible

We present extensive and accurate photometry in the near-infrared H band of a complete sample of ob- jects in an area of about 400 arcmin 2 toward the Coma cluster of galaxies. The sample, including about 300 ob- jects, is complete down to H 17 mag, the exact value depending on the type of magnitude (isophotal, aperture, Kron) and the particular region studied. This is six mag- nitudes below the characteristic magnitude of galaxies, well into the dwarfs' regime at the distance of the Coma cluster. For each object (star or galaxy) we provide aper- ture magnitudes computed within ve dierent apertures, the magnitude within the 22 mag arcsec 2 isophote, the Kron magnitude and radius, magnitude errors, as well as the coordinates, the isophotal area, and a stellarity index. Photometric errors are 0.2 mag at the completness limit. This sample is meant to be the zero-redshift reference for evolutionary studies of galaxies.


This study was aimed to investigate the relationship between the perceived strength of motivation and level of physical activity during their leisure time of youth. The randomly selected 1,097 (boys = 342, girls = 755) youth reported their duration, frequency, and intensity of physical activity and also indicated their strength of motivation in relation to physical activity. Two-way contingency table analyses and t tests revealed that the strength of motivation for physical activity was significantly and positively related to active participation.


As an important part of cultural system reform in Anhui Province,the cultural system reform on the state-owned artistic performance organizations in Chuzhou has gone through 30years.This article makes a relevant survey of the reform,summing up the division basis of the process and presenting evaluations and thoughts on it.


AbstractA practical collision probability model is presented for the description of geometries with many levels of heterogeneity. Regular regions of the macrogeometry are assumed to contain a stochastic mixture of spherical grains or cylindrical tubes. Simple expressions for the collision probabilities in the global geometry are obtained as a function of the collision probabilities in the macro- and microgeometries. This model was successfully implemented in the collision probability kernel of the APOLLO-1, APOLLO-2, and DRAGON lattice codes for the description of a broad range of reactor physics problems. Resonance self-shielding and depletion calculations in the microgeometries are possible because each microregion is explicitly represented.


Objective
To investigate the clinical characteristics of severe obstetric patients in the intensive medical care (ICU) in our hospital with the analysis of the age and disease distribution to guide the treatment and reduce the mortality rate.

Methods
The clinical data of severe obstetric patients who admitted in our ICU from January 2013 to January 2017 were collected. We analyzed the age, APACHE Ⅱ score, disease composition, the length of ICU stay and mortality.

Results
342 severe obstetric patients were included and the most important three diseases were gestational hypertension (116, 33.9%), postpartum hemorrhage (105, 30.7%) and organ dysfunction failure (95, 27.8%). Different disease distribution was found in different age population. Hypertensive disorders of pregnancy was most common in patients with age less than 20 years old (12/21) while gestational hypertension (56/172) and organ dysfunction failure (60/172) was most common in patients with age between 20 and 30 years old. Of 128 patients with age of 31 to 40 years old, 56 were postpartum hemorrhage and 60 developed to gestational hypertension, which were major diseases. The uniform diseases distribution was found in patients with age old than 40 years old. There were 7 postpartum hemorrhage, 6 gestational hypertension and 6 organ dysfunction patients, respectively among 21 patients. Different APACHE Ⅱ score, length of ICU stay and mortality were found in different diseases population. The death of postpartum hemorrhage, gestational hypertension, organ dysfunction failure and others was 0, 0, 5, 1 cases, respectively.

Conclusion
Gestational hypertension, postpartum hemorrhage and organ dysfunction are most common in severe obstetric patients, with different distribution in different age population. Our results indicates that strengthen assessment and early intervention can prevent complications and reduce mortality.

Every day, construction companies make efforts to bring to their customers the best option to accomplish the contract specifications, many of which can be impeded by a variety of factors. This document proposes a CONSTRUCTION SCHEDULE DELAY RAMP-UP PROGRAM so that civil works finish before the planned due dates. HEO is currently responsible for the roadworks between the municipality of Otanche Boyacá, which has a connecting route to Ruta del Sol. INVIAS contracted the project, and after 20 months of the initial construction date, execution setbacks caused delays in around 45% of the work's internal program. This slowdown represents a high risk for the project's profitability margins. Furthermore, since regulatory authorities have already started a sanctioning process, previously specified in the contract's terms, they could issue an unfavorable ruling for the overall project. We propose the creation of a CONTINGENCY PLAN to face the challenges mentioned above. This document contains the necessary Management Plans: Scope, Calendar, Costs, Quality Assurance, Communications, Risk Management, Procurement, and Stakeholders. Also, it has strategies that ensure an efficient contract execution that involves every stakeholder, as well as interest groups and other collaborators. Plan de Contingencia para Recuperación del Cronograma de Obra 3


The test area was part of a spring seeded stand of "Buffalo" alfalfa. Compounds for evaluation were applied on 6 July 1983 to 40 by 40 ft plots in 16.5 gal/acre at 40 lb/in2 using a tractor-mounted boom-type sprayer with 8002 flat fan nozzles and 50-mesh screens. Conditions at treatment were 85°F and no wind. Alfalfa was 12 in. tall. The experimental design was a randomized complete block design with untreated checks in four replications. Samples consisting of 10 (180-degree) sweeps with a 15-inch sweep net, were taken pretreatment, 24 h, 7 and 14 days posttreatment to evaluate potato leafhopper control.


Objective To explore the effects of α-tocopherol on Bcl-2 protein expression of spermatogenic cells in experimental varicocele rats. Methods Thirty adult male Wistar rats were randomly divided into 3 groups(n=10): treatment group (TG) was intramuscularly injected α- tocopherol (0.5mg/100g body weight, one time daily for 4 weeks) after establishing varicocele model by partial ligation of the left renal vein for 4 weeks, operation control group (OCG)and sham operation group (SOG). After 8 weeks Bcl-2 protein expression in the testes tissues was detected by immunohistochemical method. Results The weight of left testes in TG was obviously heavier than that in OCG(P0.05), but significantly lighter than that in SOG. The positive rate of Bcl-2 expression of both testis spermatogenic cells in TG was significantly higher than that in OCG(P0.05), and significantly lower than that in SOG(P0.05). Conclusion The Bcl-2 expression of spermatogenic cells was down-regulated in varicocele rats, and α- tocopherol could increase the Bcl-2 expression in the spermatogenic cells damaged by varicocle, and had a certain protective effect for the testes injury resulted from experimental varicocele.


Cloud computing is an emerging technology. Based on the concept of parallel computing, it greatly enhances the data processing ability and the data storage capacity. On the other hand, the combination of medical services and the cloud computing is an important industry trend. Through the medical "Internet of Things", a huge amount of data have been gathered and should be analyzed for various cloud services. Therefore in this research, the private cloud computing system has been implemented using Apache Hadoop. Data storage of the system would be based on the HDFS as well as the cloud database HBase, and various source data have been collected and imported into the distributed storage system. Functional packages from the MLlib library as well as the RHadoop software would be utilized as tools for further data exploration. Since the impact of environmental factors on physiological functions has been one of the focuses of scientific research, in the near future we would like to validate whether environmental pollutant increases the risk of disease occurrences. The ultimate goal of research is to develop the cloud services for biomedical academic research.

The internationalization of talent cultivation in the field of international higher education is a widely discussed topic among higher education institutions worldwide. This paper conducts a comparative study of domestic and foreign higher education institutions and identifies some differences in the internationalization of talent cultivation among different countries and regions. Firstly, the study summarizes the changes in talent cultivation through domestic study abroad programs and overseas study programs. Then, this paper introduces the "Knowledge-Practice-Research" international talent cultivation model in China and the international talent cultivation model in Japan as an example. Finally, this study compares the international talent cultivation models in domestic and foreign higher education institutions. The results indicate that the internationalization of talent cultivation models needs to be adjusted according to different training objectives, specific countries, and even regional circumstances to adapt to local characteristics and the international environment. Overall, different countries and regions have different emphases and characteristics in the internationalization of talent cultivation in higher education institutions. However, regardless of the country, higher education institutions should focus on enhancing students' international perspectives and cross-cultural communication skills to adapt to the globalized economic and social environment.


T he human gut host 10 14 bacterial organisms, an amount that exceeds the cells within the body. Microbiota is the bacteria living both inside and on the human body (a community collectively known as, dwelling in the human microbiome) mostly are friendly; outnumber the somatic and germ cells of the body by a factor of 10. Specific to the human gut is the commensal microflora, enters into an important symbiotic association with the human host beginning with the colonization of the Gastrointestinal (GI) tract by the bacteria within half an hour after delivery and continue to develop depending on many factors, this is developmental process begins at birth, continues through early development and remains for life. This developmental processing is actually acted during vulnerable or sensitive developmental periods and thus exerts influences that impact on the structure and function of organs (brain) that last throughout life. However, although the colonization of microbiota is due to postnatal environmental factors and is also affected by genetics, it is consistent and is difficult to change after reaching the adult form. It has a pre and post natal effect on developing infant brain. The microbiota is essential to the proper development of the mucosal and systemic immune systems and in nutrient uptake and metabolism as an important contributor in making the individual's physiology and influence the function of the central nervous system (CNS) and behavior. Of particular interest is the impact on the functional development of the infant (mammalian) brain. The developing brain is susceptible to internal and external cues during its perinatal life, an important point when considering the association between common neurodevelopmental disorders (e.g. autism, schizophrenia) and microbial pathogen infections during this same period. Breast feeding and probiotics now being recognized in the brain–gut axis interactions.


This study was conducted to investigate the economic effect of the release of seed flounder to the central area of the West Sea, which was analyzed into both direct and indirect effects. The results showed that based on the data collected from partial area, the economic effect of flounder seed release reached 6.97 times, average catch proportion was 32.27, and recapture rate was 11.26, suggesting that economic effect was very high. In addition, it was observed that the recapture rate was greatly higher than 2.05, that of Break-Even-Point. It was noted that the increased catch by the release of seed flounder resulted in the increase in commission of sales and the increase in sports fishing. Another economic effect observed were diverse including the increase in income of fishing village, elevated spirit to proper management of fisheries resources, maintaining of willingness to live in fishing village through activation of local fishing village, prevention of illegal fishing including capture of juvenile fish, and the increase in the supply of sea food of high quality. It is emphasized that although the investigation was conducted in the same area, the results will vary by size at release, time at release and other factors. Finally, there is a need to expand species and area of study for more active economic analysis incorporating natural sciences.


Introduction Future climate change will affect the germination response of native plant species. A number of native species have a large distribution range and thus may have differing germination. Temperature is an important variable affecting seed germination. To further understand the germination requirements of native prairie seed, SPARC utilizes the Thermal Gradient Plate (TGP), which features 96 cells with individual cell temperature control. Each cell is monitored with an accuracy of ±0.2°C. The TGP allows for simulation of prairie temperatures, as well as climate change.


Although several self-report inventories of assertive behaviors are available for clinical and research use, normative data currently available on these measures provide only a gross index with regard to an individual's assertiveness relative to others in his social milieu. The purpose of this study was to develop more specific normative data for the Rathus Assertiveness Schedcule (RAS). The RAS was administered to 133 undergraduate men and women, and percentile norms were developed from the obtained distribution of total scores. In addition, derived scores were calculated from Z score norms developed for each item. The percentile norms provide information on an individual's over all assertiveness relative to others in his social milieu, while the item norms provide information as to relative assertiveness in specific target situations. It is suggested that the percentile norms might prove most useful in research with groups for which only a gross index of relative assertiveness is required. Normative data for the items of the RAS should be clinically useful, not only to pinpoint areas of deficit assertive behavior, but also to assess behavior change after therapeutic intervention. The need for additional research is discussed.


The authors examined a college mathematics professor's change process in teaching practice by analyzing the teacher's reflective journal. Her change engaged cooperative learning method in a college Algebra course and was geared toward the reform-oriented methods. The change processes were revealed as a bumpy road that was full of struggles and challenges to both the teacher and students. The analysis also showed that a reflective journey needed a proper means and support system from a teacher's environment such as institution. This research clearly showed that brining a genuine change in teaching practice toward a broad educational goal was a combined effort among the participants of education.


Objective
To investigate the effects of Lactobacillus rhamnosus GG (LGG) colonization in early life on intestinal barrier and intestinal development in offspring mice and its possible mechanism.

Methods
Six C57BL/6 pregnant mice with the same conception time of 6 weeks were selected and randomly divided into experiment group given 108 cfu/ml LGG live bacteria and control group given LGG inactivated bacteria by gavage from the 18th day of pregnancy until natural birth. The progeny mice in the two groups were continued to be gavaged with 107 cfu/ml of LGG live bacteria or LGG inactivated bacteria on days 1-5 of birth. The body weight changes of 3 week'progeny mice were recorded. The colonization of LGG bacteria in offspring mice was detected at 2nd and 3rd weeks. The mRNA of intestinal proinflammatory cytokines and tight junction molecules were evaluated by real-time PCR method. HE, immunohistochemistry, immunofluorescence staining and enzyme-linked immunosorbent assay were used to evaluate the intestinal barrier of 3-week old off spring mice.

Results
Compared with the control group, the progeny mice of the experiment group showed no significant difference in body weight at the first week, and the body weight increased at the second week and the third week [2nd week: (3.790±0.240)g vs.(4.326±0.140)g, t=3.707, P=0.006; 3rd week: (7.295±0.326)g vs. (8.040±0.370)g, t=3.130, P=0.011]. LGG colonization can be detected only in the feces of progeny mice in the experiment group. Intestinal colonization can promote the growth of small intestine villi and colon crypt depth[jejunum: (320.000±22.514)μm vs.(265.100±15.611)μm, t=8.258, P<0.001; ileum: (150.500±13.099)μm vs.(111.000±11.308)μm, t=9.958, P<0.001; colon: (295.000±15.209)μm vs.(233.100±6.678)μm, t=9.129, P<0.001]. Compared with the control group, the number of goblet cells in the colonic crypt of the experiment group increased(11.62±0.780 vs. 35.24 ±1.370, t=15.000, P<0.001), and the relative mRNA expression levels of pro-inflammatory factors as IFN-γ (1.280±0.232 vs. 0.512±0.206, t=4.970, P=0.001), IL-6(1.364±0.271 vs. 0.941±0.215, t=2.452, P=0.040), IL-10(1.341±0.320 vs. 0.744±0.294, t=2.762, P=0.025) and TNF-α(3.702±0.150 vs. 2.581±0.500, t=2.553, P=0.034) in the experiment group decreased; the expression levels of the intimate tight junction molecules (Claudin3)(1.283±0.152 vs. 1.881±0.172, t=4.932, P=0.001)and the atresia protein molecule (Occludin)( 1.164±0.342 vs. 0.812±0.224, t=3.67, P=0.016) significantly increased.

Conclusion
Early life LGG colonization protects the intestinal barrier by inhibiting low-grade intestinal inflammation. This study will lay the experimental foundation for the supplementation of probiotics in early life so as to prevent intestinal diseases.

First‐ and second‐order reflection effects in oblique incidence surface acoustic wave gratings are examined. A general formulation usable for both metallic and same material grooved overlays is provided. The existence of several important effects, particularly a reflection effect at the second harmonic of the grating and a velocity shift at the first harmonic for grooved gratings, are demonstrated, and the behavior of these effects as a function of incidence angle is examined. For angles of incidence of interest in the production of reflective array compressors, these effects are analyzed as a function of metallization ratio.

Wage/price controls are likely to recur from time to time as instruments of U.S. economic policy. Although never officially acknowledged, the emphasis on the wage side to such controls—particularly the union wage side—is always apparent. Price controls are generally based on a markup over costs, a system which assumes control of wages. Data from the Phase II period illustrate the need for more gradualism and less ideology.


Objective To identify the distribution of the laminin α5,α2 and γ1 chains within renal basement membrane in Alport syndrome (AS). Methods Kidney tissues from 11 patients of AS, 9 IgA nephropathy (IgAN) , 6 focal segmental glomerular sclerosis (FSGS) , 5 thin basement membrane disease (TBMD), 6 minor change glomerulonephritis and 3 normal people were examined by immunofluorescence and confocal microscopy for the expression of laminin α5,α2 and γ1 chains. Among 11 Alport patients, 8 male and 2 female patients inherited as X-linked dominant trait and 1 female inherited as dominant trait. The expression of the α3,5 chains of type IV collagen in GBM were co-absent in all 8 male Alport patients and were partially absent in 2 female patients, whereas their expression were normal in another female patient. Results Laminin α2 chain was deposited in the mesangium and absent from GBM in normal people, but was abnormally deposited in Alport GBM. GBM laminin α2 chain deposition was not observed in IgAN, FSGS, TBMD and minor change glomerulonephritis. As in normal kidney, Alport kidney revealed similar staining for the laminin α5 and γ1 chains. Conclusions Laminin is one of the main components in GBM and mesangium. Abnormal deposidon of laminin α2 chain is of clinical importance in AS diagnosis.


Surface resistance measurements of films of YBa2Cu3O7 deposited onto single‐crystal substrates of LaGaO3 and SrTiO3 have been made at a frequency of 22 GHz. The measurements were made in either a copper or niobium cavity by replacing the end wall with the superconducting film. Typical surface resistance at 20 K are 1–2 mΩ for films on LaGaO3 and 6–8 mΩ for films on SrTiO3, as measured in the copper cavity. The LaGaO3 values lie within the sensitivity range of the Cu cavity (∼2 mΩ) and can only be considered upper limits. Similar measurements in a Nb superconducting cavity resulted in a surface resistance value of 0.2±0.1 mΩ at 4 K for the best LaGaO3‐based film. This value is more than an order of magnitude lower than Cu, and suggests that LaGaO3‐based films may offer immediate advantages in a number of applications.


As university researchers, we face a significant obstacle when we study schools: our lives as researchers began in schools; a condition of our inquiry is that we were ourselves successful in school. Having never really left, when we return to schools, now as an object or site of our study, we therefore revisit the scenes of our own becoming. Britzman (2007), thinking about the implications of this history for practices of teacher education, describes the problem as follows:


This work presents a comprehensive investigation on the modeling and characterization of the direct-tunneling (DT) current in ultrathin-gate dielectric film based on the classical model equation. Merit of replacement, which takes both the capacitance gain and the DT current suppression into consideration, was introduced to have a better comparison of different gate dielectric materials. A simple approach for modeling the dual-layer dielectric film is also developed. The tunneling characteristics of a dual-layer stack are modeled with an effective barrier and an effective thickness. The simple approach is particularly useful for device designs and process evaluation.


The spatial distribution of the eggs of Diabrotica Longicornis (Say) was studied and it was found that 85% of the eggs in the upper 20 cm of soil were in the top 10 cm. The base of corn plants and cracks in the soil were preferred oviposition sites. It was concluded that a sampling program should include samples at the plant base and between rows to a depth of 10 cm. Of 5 sampling methods evaluated with regard to variability and time, three were statistically reliable. The 'normal core method,' which used a 5.4 cm diam core sampler, was the most efficient with regard to time, but a newly-developed 'frame method' was recommended as most accurate. An equation was developed to give the percentage confidence that the egg population is below the economic threshold for varying numbers of samples and mean number of eggs per sample.


The present work is devoted to investigation of the compressive fracture for piecewise homogeneous materials with specific kinds of delaminations (defects with connected edges). The critical buckling strains and loads at which ply instability in laminated composites occurs under uniaxial and biaxial compression were evaluated. Different types of layers (linear elastic, elastic‐plastic, hyper‐elastic incompressible) were investigated. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Abstract This paper describes an adaptive extended Kalman filter (AEKF) approach for geo-referencing tasks for a multi-sensor system (MSS). The MSS is a sensor fusion of a phase-measuring terrestrial laser scanner (TLS) with navigation sensors such as Global Navigation Satellite System (GNSS) equipment and inclinometers. The position and orientation of the MSS are the main parameters which are constant on a station and will be derived by a Kalman filtering process. Hence, the orientation of a TLS/MSS can be done without any demand for other artificial targets in the scanning area. However, using inclinometer measurements the spatial rotation angles about the X- and Y-axis of the fixed MSS station can be estimated by the AEKF. This makes it possible to determine all six degrees of freedom of the transformation from a sensor-defined to a global coordinate system. The paper gives a detailed discussion of the strategy used for the direct geo-referencing. The AEKF for the transformation parameters estimation is presented with focus on the modelling of the MSS motion. The usefulness of the suggested approach will be demonstrated using practical investigations.

The present invention relates to a nickel-supported catalyst for combined reforming, and more particularly to supported nickel active metal in the lanthanum oxide support, as a catalyst used in the process for producing a synthesis gas and at the same time combined reforming of natural gas with steam and carbon dioxide to relate to the manufacture of nickel-supported catalyst.


Irish presidential elections have sometimes been characterised as part of a 'culture war', where different sides of a cultural and policy space compete for the 'soul of Ireland'. Alternatively, voters might choose on the basis of partisan loyalties, candidate characteristics, or as a way of punishing, rewarding or influencing government. This article argues that the 2011 presidential election was almost an ideology-free zone where candidates' positions on specific issues were less important than their ability to withstand character tests. It argues that despite Higgins's landslide victory, his support was soft, and only came to him after all other candidates had been effectively eliminated from contention by allegations during the campaign.


The feeding activity, mating frequency, attraction, sexual response, and mortality of normal Anthonomus grandis Boheman were compared with boll weevils irradiated with 6388 or 12,775 rad of Co60 gamma radiation. The irradiated weevils equaled normal weevils in each aspect of behavior for at least 5 days posttreatment. However, by the 7th day posttreatment, all these activities had started to decline in the treated weevils and all irradiated weevils were dead by the end of the 2nd week. Thus, irradiated boll weevils may be effective in a program involving the release of sterile insects, but the releases would have to be made at least weekly and preferably every 5 days.

The surface of Ti6Al4V alloy is treated by sand-blasting method,and the HA biomimetic coating is formed on Ti6Al4V alloy though the optimization of the process paramaters such as the consistence of acid and alkali,treatment method,temperature and time.The morphology,component and structure of the coatings are characterized by SEM and XRD.The mechanism of the biomimetic growth on the surface of Ti6Al4V alloy is simulated by computer analysis.The results indicate that the sand-blasting and pretreating for the surface can afford the more strength of the integration between the interfaces,and the biomimetic growth coating is the alike-ostein apatite.


A method of measuring the intensity of the Ghost line produced by the grating is given for the Solar Spectral Telescope at Yunnan Observatory in this paper.A preliminary result about the intensity of the Rowland Ghost line for the second order spectrum is obtained.The intensity of the Ghost line is 0.049% of the main line. It is indicated that the Ghost line is very weak compared with the main line and the grating is excellent in quality.An influence of the Ghost line to spectral measurement is very small,in general,it is not necessary to correct the influence in spectral data processing.


This review aims to outline the effectiveness of employer-initiated workplace interventions in promoting sustainable employability (SE), which means developing workers' capabilities to foster productivity, health, and valuable work in the long term. A systematic search of the literature is performed in three databases covering the period from January 1999 to February 2022. Fourteen studies are included. Considering SE core components, all interventions cover the valuable work component in terms of content, and the majority also cover the health component. Interventions addressing at least three SE components have more positive effects on SE outcomes. More positive effects are found for valuable work outcomes. Overall, the findings highlight the importance of developing workplace interventions considering a comprehensive model of SE and promoting an organizational culture for SE. Future directions and limits are discussed.


Abstract Extremely low frequency (ELF) magnetic and electric fields were measured in four microelectronics fabrication rooms that utilized a variety of electrical devices. Magnetic field levels measured in the aisles of the workrooms ranged from 0.2 to 7.0 mG; electric field levels ranged from 0.1 to 5.0 V/m. At 2 inches from the surfaces of various workroom devices, magnetic field levels ranged from 5 to 400 mG; at 2 feet from the device surfaces, levels ranged from 0.5 to 70 mG. From the measured levels and information obtained on typical work patterns, 8-hour time-weighted average personal exposures were estimated for various work scenarios.


Currently, Pelkmans is developing a new test allowing the detection of bleeding and thrombosis tendencies by measuring thrombin generation as well as fibrin formation. An important characteristic of this new test is measurements being carried out under flow conditions, whereas current tests measure under (almost) static conditions. As a result of the test measuring under blood flow conditions, a more factual approach to the human body is used. In addition, the number of laboratory tests is reduced as two parameters usually tested separately are now measured simultaneously. Pelkmans also studied tests used to indicate the presence of the antiphospholipid syndrome (APS), which is characterised by thrombosis and/or pregnancy complications. The presence of this syndrome is indicated by using laboratory tests which are not always accurate methods for diagnosis of this syndrome. Therefore, she initiated the development of a new test aimed at improving the diagnosis and treatment of APS.


The sensor is quite easily attacked or invaded during the process of the node coverage optimization. It is a great challenge to make sure that the wireless sensor network could still carry out a secure communication and reliable coverage under the condition of being attacked. Therefore, this paper proposes a network coverage method for intrusion tolerance based on trust value of nodes by combining the trust value model with the reliable coverage optimization. It first estimates trust value of nodes through which to regulate the perception radius and decision-making radius. Furthermore, this algorithm also combines the classical methods of wireless network coverage, such as GSO and PSO, to realize the networks coverage of invasive tolerant sensor. After comparing with the conventional single cover mechanism, it can improve the security and coverage rate of network under the condition of invasion. The simulation results verify the effectiveness of the algorithm.


At present, education is not only a source of educational services but also the most important socio-economic institution, by means of which knowledge is transferred and a new level of civilization is formed. Each teacher at a modern university is faced with the phenomenon of digital technologies, which in turn are poorly subjected to external control. At the same time, search for indicators of educational institutions efficiency increase. The problem is viewed in the context of understanding of the digital economy in terms of global leadership. This defined the purpose of the study, which is to find factors that influence the formation of the personality of a modern teacher – a teacher of history – in the process of professional training. This study is based on analytically-synthetic and institutional theoretical approaches and comparative-generalizing theoretical method, as well as on following empirical methods: questionnaire analysis, included observation, interviews, focus groups study. Students of the History Faculty control and the experimental groups 59&58 were involved. The study also involved 35 teachers (aged 29 to 68) in 2018-2019 academic year. As a result of the research, we found a number of risks that influence the formation of the personality of a modern teacher – a teacher of history. Digitalization of the university's educational space in the preparation of a future teacher leads to the disappearance of live communication and the transfer of implicit knowledge, changing the abilities for empathy, experience and complicity and, forming neurosis, depression, mistrust of others and balanced combination of collective and social-communicative forms of interaction with the active involvement of digital technologies is important.


Abstract. This paper presents an overview of the MRL small size robotic team. This paper describes three of the main changes to the MRL RoboCup team which lead us to Smart Start. The first part explains the advantages which E-League had for undergraduate students. The second part covers the electrical, mechanical and control parts of robot. Next part describes our development on a new Vision system using smart scanning technique. Moreover, a robust filter on variable lighting condition and path planning improvement based on potential filed algorithm. Finally, the last part introduces MRL 3D Simulator which developed to investigate the control commands. 1 Introduction The Azad University of Qazvin's MRL RoboCup team established due to research in Mechatronics and Robotics in Mechatronics Research Laboratory. A year of hard effort leads to qualification in E-League competition. Although we missed the game but E-League experiences was a fairly good initiation to construct our small size team. The E-League competition shows us the straight path to SSL and the fundamental of a robotics team. Unfortunately this year the E-League competition eliminated in RoboCup but we suggest reestablishing this project and acting as a league for the beginners. Due to fundamental differences in E-League and SSL, team focused on major development in robot. Moreover, read other champion teams specially Cornell team which has a powerful team description [1]. The main problem was on Artificial Intelligent which is the brain of robots. We overcome this by cooperation of MRL's Coach Simulation team which took 1


We analyze numerical-relativity (NR) waveforms that cover nine orbits (18 gravitational-wave cycles) before merger of an equal-mass system with low eccentricity, with numerical uncertainties of 0.25 radians in the phase and 2% in the amplitude; such accuracy allows a direct comparison with post-Newtonian (PN) waveforms. We focus on waveforms predicted by one of the PN approximants that has been proposed for use in gravitational-wave data analysis, restricted 3.5PN TaylorT1, and compare these with a section of the numerical waveform from the second to the eighth orbit, which is about one and a half orbits before merger. This corresponds to a gravitational-wave frequency range of M{omega}=0.0455 to 0.1 Depending on the method of matching PN and NR waveforms, the accumulated phase disagreement over this frequency range can be within numerical uncertainty. Similar results are found in comparisons with an alternative PN approximant, 3PN TaylorT3. The amplitude disagreement, on the other hand, is around 6%, but roughly constant for all 13 cycles that are compared, suggesting that for the purpose of producing 'hybrid waveforms', only 4.5 orbits need be simulated to match PN and NR waves with the same accuracy as is possible with nine orbits. If, however, we model the amplitudemore » up to 2.5PN order, numerical and post-Newtonian amplitude disagreement is close to the numerical error of 2%.« less

Inorganic Polymer Concrete, a type of Alkali activated cement and concrete, is known for various excellent performances, especially for better performance in the area of high temperature heat resistance(thermal characteristic) than portland cement concrete.In this study, light weight concrete panel was manufactured using this Inorganic Polymer Concrete and then evaluated for fire resistance with a small-scale heating furnace. Since the result showed excellent fire resistance, it is considered usable for manufacturing fire resistant concrete panel wall.


We recently reported on the immigration medical surveillance program for TB in Ontario. While we agree with the assertion of the accompanying editorial that TB control must be considered in the global context, we do not agree with the apparent suggestion that TB prevention programs among high-risk immigrants in Canada be discontinued. Two prospective and one retrospective study in Canada suggest that persons referred for medical surveillance for TB are at increased risk for TB. These studies found that 1.5-2.8% of persons referred for medical surveillance were diagnosed with active TB at their first medical evaluation in Canada. In the Netherlands an immigration screening program detected cases earlier, resulting in fewer hospital admissions, shorter duration of symptoms and therefore probably reduced tuberculosis transmission. In the face of the increasing prevalence of TB HIV co-infection and multidrug-resistant TB, tolerance for local transmission needs to be close to zero. Serious attempts to reduce transmission as well as to make a timely diagnosis to optimize the health of the affected individual are required. Clearly operational shortcomings, such as referral of low-risk populations, poor notification and lack of appropriate medical follow-up will seriously compromise the effectiveness of any program. The task facing TB controllers in Canada is the repair and maintenance of the referral program. TB among persons migrating to countries that enjoy a higher level of development will continue to dominate the TB control concerns of the receiving countries. It is the obligation of TB control officers in these countries to protect the interests of their population. It is clear from our study that there are major problems with the medical surveillance program in Ontario. Clearly we are missing opportunities to reduce the future burden of TB in Canada. We strongly believe that evidence-based redesign of the system will better preserve the health of Canadians than dismantling it.


The discussion about the proper way to conduct scientific research has been a recurrent theme in a series of study areas. In search of more relevant studies, but at the same time maintaining the necessary rigor to a scientific research, it is possible to use design science as a paradigm for conducting research in the field of production engineering and operations management. However, few discussions are made to understand the ontological and epistemological basis for design science. From this context, this thesis aims to distinguish and propose the ontological and epistemological foundations for knowledge created in production engineering and operations management, under the paradigm of design science. To reach this goal, this research adopted a theoretical-conceptual and, also, empirical character. Thus, in the first phase of the research, the demarcation criteria were proposed, which distinguish and characterize knowledge in design science and, also, an epistemological structure that represents the process of production of this knowledge. These conceptual constructions were duly evaluated by a group of experts and sought to contribute to the understanding of the knowledge nature in design science and how it is produced. The second phase of the research deals with the analysis of researches (theses, dissertations, and articles) based on design science in production engineering and operations management in the light of the demarcation criteria and the proposed epistemological structure. From the conduction of this second phase, it was possible to characterize the knowledge produced by the analyzed works, as well as to verify good practices adopted by the researchers. Finally, the third phase, which has an empirical nature, was conducted through field studies, which allowed to identify how the production of technological knowledge occurs in the business context and in what way it relates to knowledge in design science. About the research results, it can be evidenced that from the use of the proposed demarcation criteria, it becomes possible to guide and evaluate the quality of the works that are being conducted under the paradigm of design science. The proposed epistemological structure, in turn, can be used as an instrument to support the research process, assisting in the generation and accumulation of knowledge in design science in the scope of production engineering and operations management. In addition, such structure can contribute to the clarification of the theoretical contributions of research, either to the knowledge base in design science, in the form of design theory, or to traditional science.


The hemispheric dichotomy is a fundamental feature of Mars, expressed by a physiographic and geologic divide between the heavily cratered southern highlands and the relatively smooth plains of the northern lowlands. The origin of the dichotomy, which may have set the course for most of the subsequent geologic evolution of Mars, remains unclear. Internally driven models for the dichotomy form the lowlands by mantle convection, plate tectonics, or early mantle overturn. Externally driven models invoke one giant impact or multiple impacts. Areal densities of buried basins, expressed by quasicircular depressions and subsurface echoes in radar sounding data, suggest that the dichotomy formed early in the geologic evolution of Mars. Tectonic features along the dichotomy boundary suggest late-stage modification by flexure or relaxation of the highlands after volcanic resurfacing of the northern lowlands. Subsequent deposition and erosion by fluvial, aeolian, and glacial processes shaped the present-day dichotomy boundary.


This article focuses anecdotally on the therapeutic powers of poetry and of the poet himself or herself as a direct agent in the healing process. Four long poems-by Adam Mickiewicz, Thomas Gray, Robert Browning, and Walt Whitman-that won unexpectedly profound acceptance from a hospital audience of mentally ill people are analyzed in depth. What the poems have in common is that each demonstrates dramatically the poet's liberating role. Other episodes of a similar nature follow, culminating in a remarkable moment when a fast-fading tubercular schizophrenic was literally resuscitated by a cassette recording of his own voice reciting his own affirmative poetry. The poets are liberating Gods.Ralph Waldo Emerson'


All traditional sectors are being transformed to a large extent as technology advances. Some examples are smart homes, smart systems, smart playgrounds, smart cities, and so on. There is no exception in the education sector. The modern smart classroom concept is not new, but it is much more effective and efficient using cloud based systems. Machine learning, virtual reality, and augmented reality serve as foundations for creating a modern classroom environment. The data created by these technologies necessitates a large amount of storage space. The cloud makes it possible to do so. The need for latency can be met by choosing the closest datacenter. Users will be able to collaborate closely with resources in the modern environment. Users will be able to work closely with multiple resources in the current environment, and they will have access to them whenever they want. Amazon Web Services, Microsoft Azure, Google Cloud Platform, and others are examples of cloud service companies. Cloud service providers ensure that data is available to users at all times and in all places.


An important component of Space Situational Awareness (SSA) is knowledge of the status and tasking of blue forces (e.g. satellites and ground stations) and the rapid determination of the impacts of real or hypothetical changes and the ability to quickly replan based on those changes. For example, if an antenna goes down (either for benign reasons or from purposeful interference) determining which missions will be impacted is important. It is not simply the set of missions that were scheduled to utilize that antenna, because highly expert human schedulers will respond to the outage by intelligently replanning the real-time schedule. Similarly if there is a vehicle emergency or a vehicle must be quickly maneuvered because of a possible collision, in addition to scheduling the required supports, minimizing the impact of the added support must also be performed We have developed an automatic scheduling and deconfliction engine, called MIDAS (for Managed Intelligent Deconfliction And Scheduling) that interfaces to the current legacy system (ESD 2.7) which can perform this replanning function automatically. In addition to determining the impact of failed resources, MIDAS can also replan in response to a satellite under attack. In this situation, additional supports must be quickly scheduled and executed (while minimizing impacts to other missions). Because MIDAS is a fully automatic system, replacing a current human labor-intensive process, and provides very rapid turnaround (seconds) it can also be used by commanders to consider what-if questions and focus limited protection resources on the most critical resources. For example, the commander can determine the impact of a successful attack on one of two ground stations and place heavier emphasis on protecting the station whose loss would create the most severe impacts. The system is currently transitioning to operational use. The MIDAS system and its interface to the legacy ESD 2.7 system will be described along with the ConOps for different types of detailed operational scenarios.

as thirty years. Plastic scleral lenses were introduced in the United States about 1940 and in this country about 1945. So far the approach had been to support the lens on the sclera avoiding corneal touch or at any rate corneal pressure. In 1948 Tuohy in America introduced the small corneal contact lenses and while thescleral lens has continued to be developed in this country the corneal lens has swept the field elsewhere. We do not know how many people are wearing contact lenses but many millions of corneal lenses have been sold in the United States. In this country


Among the minerals dissolved in seawater some occur in quite high concentrations. Such is for instance the case for salt (NaCl), magnesium (Mg) and bromine (Br), but also for sulphur (S), calcium (Ca), potassium (K), boron (B) and-although in lesser quantities-for iodine (I). Salt, magnesium and bromine from marine origin have been exploited on a large scale; salt from times immemorial, the others since numerous decades. In 2000 close to 15 million ton of salt were extracted from the sea, representing 7% of worldwide total salt production. In the same year marine magnesium production amounted to 1.8 million ton or 51% of total magnesium production. Even better, marine bromine production was 380,000 ton or 70% of total world production. But to what extent are those mineral exploitations sustainable and for how long can such operations continue? In view of the industry's demand for these minerals and the very large share of marine origin the question is both pertinent and answers are urgent. The military demands for these minerals, during World War II, contributed largely to the development of mining operations while the expansion of the car industry and the need for a no-knock-gasoline spurred the production of bromine. Equally pressing is the question of the impacts such exploitations exert on the environment, both offshore and in the coastal zone. Last but not least, is the use of those minerals not harmful for the environment in general?

This paper describes our Georeferencing approaches, experiments, and results at the MediaEval 2011 Placing Task evaluation. The task consists of predicting the most probable geographical coordinates of Flickr videos. Our approaches used only Flickr users textual annotations and tagsets to predict. We used three approaches for this task: 1) a Geographical Knowledge approach, 2) an Information Retrieval based approach with Re-Ranking, and 3) a combination of both (GeoFusion). The GeoFusion approach achieved the best results within the margin of errors from 10km to 10000km.


Dye-sensitized solar cells (DSSCs) have attracted great interest as potential candidates of "low cost solar cells" in the solution of global energy demand. To accelerate the progress of DSSCs, it is important to evaluate device performance with reliable measurements that will enable more effective comparison and application of new findings in materials and technologies by different research groups. In this perspective, Lagerstroemia Speciosa Flowers dye was extracted using two methods of soxhlet and cold ethanol extraction. Our findings show that the open-circuit voltage is low which might be due to reduction in electron conduction .The Conversion efficiency of cold ethanol dye extract is higher than that of the soxhlet ethanol dye extract, which indicate that the dye pigment is more degraded in the latter method. However with further investigation, the constructed DSSC's be made to serve as a power source for driving self-powered devices. Key word: - lagerstroemia speciosa flowers, Ethanol, Dye Sensitized Solar Cells

To improve the dynamic characteristics of the airborne electronic equipment structure,and its working reliability,the modality of airborne electronic equipment is analyzed in combination with the finite element analysis software. According to the fundamental theory of modal analysis,the finite element simulation model of airborne electronic equipment was established by means of ANSYS Workbench software. The inherent frequency and corresponding vibration mode of the airborne electronic equipment are calculated by finite element analysis of the vibration characteristics,and the resonance phenomenon of the equipment in use is avoided,which provides a valuable reference for further optimization design of airborne electronic equipment,and can reduce the design cost of airborne electronic equipment effectively and shorten the developing cycle.

In this paper we derive calculable bounds for the error in two‐body s‐wave scattering calculations done by the complex‐coordinate method. In the process we derive a bound on the error in the Born approximation. The utility of the results is discussed in light of simple examples.


A large amount of piggery wastewater is produced from the pig farm, which contains a great amount of ammonia nitrogen, organic matter and pathogenic bacteria. The wastewater that is stinking and blackened can cause great harm to the environment if not treated in time. In this experiment, piggery wastewater was pretreated by adding flocculant to investigate the effect of the flocculant type, adding amount and settling time on the experiment results. The results indicated that it can effectively remove the pollutants by adding 25 ppm of nonionic F140 (PAM) and 100 ppm of polyaluminum chloride (PAC) to the piggery wastewater.


venous system, brought about by man's upright posture and gravitational forces, affects about 70% of all adults over 60.' The ever growing world population and man's increasing life span ensure that varicose veins will continue to be a progressive problem of therapeutic importance. The true cause of primary varicose veins is a subject of controversy. Some investigators believe the cause to be a result of incompetent valves in the perforating veins between the superficial and deep venous systems, since these are prevalent in documented cases.2-4 Other investigatorS5 support the theory that the cause is a congenital defect involving variation in the number and distribution of venous valves. They have provided data that suggest that varicose veins have far fewer valves than do normal


The fluctuation of the clothing pressure was analyzed. The amplitude of the fluctuation was affected by the positions of a subject rather than the shape of wearing clothes. Under static conditions a peak at 0.2_??_0.4 Hz was observed in the power spectrum owing to the respiration. In the lower frequency range of the peak the spectrum changed depending upon the clothes and the positions. The spectrum components in this range appeared remarkably in the case of comfortable clothes or positions. The results showed that the analysis of the fluctuation in the clothing pressure was useful to evaluate the comfort of the clothes.


Digital technologies are being used to combat the coronavirus disease 2019 (COVID-19) pandemic through a variety of methods, including monitoring compliance with quarantine and contact tracing. These uses of technology are said to promote public health outcomes but risk undermining rights to privacy. In this article we focus on the use of digital technologies for contact tracing, such as the COVIDSafe app used in Australia. We explore the kind of framework that might be used for evaluating the design, deployment and governance of such technologies to ensure they operate in a manner that is proportionate to the ends to be achieved. We conclude that, in addition to issues of privacy, any use of contact tracing technology should address important considerations of efficacy, equity and accountability.


YOVI REDHIA MULSI. The Effectiveness of Honey Purity Test on Apis mellifera, Apis cerana, Apis dorsata, and Trigona spp Honey. Supervised by HOTNIDA CH SIREGAR and AFTON ATABANY. Marketed honey in Indonesia originated from A. mellifera, A. cerana, A. dorsata and Trigona spp. High price and demand of honey open up opportunity to adulterate honey. Some manual honey purity test have been studied only on A.mellifera honey. The reseacrch aimed to measure and analyze the effectiveness of various purity honey test from various honey bee spesies and source. This research used Completely Randomized Design with spesies of bees as the treatment. The observed variable was the effectiveness of honey purity tests such as soluble test, turbidity and froth test, heated test, hexagon test, seepage test, raw fish test and onion test. The result showed that the effectiveness of the tests was not affected by bees spesies. Soluble test, heated test and seepage test were the most effective tests to proof honey purity of tree Apis bees and Trigona bee with 100% of accuracy. Turbidity and froth test also hexagon test were quite effective with level of accuracy 84.25% and 99.6%. Raw fish test and onion tests were not effective with level of accuracy 73.5%.


in a continuous flow stirred tank reactor (CSTR). The path of the perturbation (immediate quenching of oscillation, inhibition time, resumption of oscillations) caused by iron complexes was found to be different and dependent on the oxidation state of iron in the complex. The initial concentration of [Fe(bipy)3] 2+ complex showed a linear dependence on the inhibition time. Interestingly, the mode of perturbation induced by iron in free/aqua form {[Fe(OH2)6] 2+ and [Fe(OH2)6] 3+ } was found to be similar to that of ferric complex [Fe(C2O4)3] 3.


Over time mask makers have been driven to low sensitivity e-beam resist materials to meet lithographic patterning needs. For 7-nm logic node, resolution enhancement techniques continue to evolve bringing more complexity on mask and additional mask builds per layer. As demonstrated in literature, low sensitivity materials are needed for low line edge roughness (LER) but impact write tool through put. In characterizing resist sensitivity for 7-nm, we explore more broadly what advantages and disadvantages moving to lower sensitivity resist materials brings, where LER, critical dimension uniformity, resolution, fogging, image placement, and write time results and trends are presented. In this paper, resist material performance are reported for sensitivities ranging from 20 to 130 μC/cm2 at 50% proximity effect correction, where the exposure will be using a single beam platform. Materials examined include negative tone resist types with chemical amplification and positive tone without chemical amplification focusing on overall trends for 7-nm e-beam resist performance.


Using the dataset from the Asian Barometer Survey conducted in 2010-2012, we determine the variations in political participation across socioeconomic classes in five Southeast Asian countries and apply Oaxaca decomposition method to explain the variations. In general, we find high rates of voting participation across classes in Indonesia, Malaysia, the Philippines, and Thailand. In Singapore, barely half of the sample voted in previous elections. In Indonesia, Thailand, and Malaysia, the middle classes distinguish themselves from the rest by participating in other political activities, including contacting officials or the news media, joining others to voice out or directly address their common concerns, and attending rallies or demonstrations. Furthermore, interclass differences in political participation is due more to divergence in mean characteristics in Thailand, but they are due more to the heterogeneous effects of these characteristics in Indonesia and Malaysia. Relative to the middle classes in these three countries, those in the Philippines and Singapore each appears politically disengaged.


There will, I venture to think, be no difference of opinion among the members of this Institute as to the advisability of an early and adequate discussion of the many points of difficulty presented by the new Assurance Companies Act. Neither will there be any doubt as to this Institute being the proper place for such a discussion, consisting as it does of an unrivalled body of experts on the subject of life assurance. In these circumstances I have ventured to undertake the task of bringing the matter before the Institute, confident in the fact that however inadequate my treatment of the subject may be, those before whom the paper is to be read are fully competent to make good any shortcomings on my part, and will be both able and willing to correct any errors into which I may have fallen.


The Czechs have given the world many important personalities, including pedagogues. In addition to the well-known Jan Amos Komenský (1592 – 1670), we can also name Gustav Adolf Lindner (1828 – 1887). But for a long time another important pedagogue personality of the 20th century, Přemysl Pitter, remained unknown to the world. In today's world of intolerance it's worthwhile to pay attention to the activities of a man who cherished the values by which he lived his life: "Without love, without human compassion with one another, nothing will stand" (Pitter 1974). These are the words of the humanist Přemysl Pitter, a Czech Protestant-oriented thinker, educator, writer, publicist, radical pacifist, and social worker. He founded the famous Prague educational institute "Milíč Houseˮ during the Second World War, and despite strict prohibitions, he visited and supplied the Jews during that time. After the war, he applied for confiscated castles around Prague, where he took care of impoverished German, Jewish, Polish, Czech, and other children. There was no word of him for many years. But why was his birth declared a UNESCO anniversary? Why did he receive one of the highest state awards of the Czech Republic from President Václav Havel? This text addresses such questions.


Motor impersistence is known to occur more frequent after the right hemispheric lesion than the left. It is thus expected that, for a patient with a callosal lesion, motor impersistence may occur more frequently in the right (dominant) limb than the left. A 66-year-old right-handed man with an infarction involving the right medial frontal lobe and anterior corpus callosum developed motor impersistence in the right limb on bedside evaluation, which was also substantiated by an experiment using a finger dynamometer.

Abstract We examine a semigroup analogue of the Kumjian–Renault representation of C*-algebras with Cartan subalgebras on twisted groupoids. Specifically, we represent semigroups with distinguished normal subsemigroups as 'slice-sections' of groupoid bundles.


PurposeThis study aims to investigate the impact of skills and knowledge of employees, economic situations of the company, current IT infrastructure, payment fashion, cloud availability, and cloud privacy and security on the productivity of the human resources in the COVID-19 era.Design/methodology/approachOver the past few years, the advent of cloud-assisted technologies has dramatically advanced the Information Technology (IT)-based industries by providing everything as a service. Cloud computing is recognized as a growing technology among companies around the world. One of the most critical cloud applications is deploying systems and organizational resources, especially systems whose deployment costs are high. Manpower is one of the basic and vital resources of the organization, and organizations need an efficient workforce to achieve their goals. But, in the COVID-19 era, human resources' productivity can be reduced due to stress, high labor force, reduced organizational performance and profits, unfavorable organizational conditions, inability to manage and lack of training. Therefore, this study tries to investigate the productivity of human resources in the COVID-19 era. Data were collected from the medium-sized companies through a questionnaire. Distributed questionnaires were conducted on the Likert scale. The model is assessed using the structural equation modeling technique to examine its reliability and validity. The study is a library method and literature review. A case study was conducted through a questionnaire and statistical analysis by SPSS 25 and SMART-PLS.FindingsBased on the findings, the skills and knowledge of employees, the economic situations of the company, payment fashion, cloud availability and the current IT infrastructures of the company have a positive impact on human resource efficiency in the COVID-19 era. But cloud privacy and security have a negative effect on the productivity of human resources. The findings can be the basis for companies and organizations in the COVID-19 era.Research limitations/implicationsThis study has some restrictions that need to be considered in evaluating the obtained results. First, due to the prevalence of Coronavirus, access to information from the companies under study was limited. Second, this research may have overlooked other variables that affect human resource productivity in the COVID-19 era. Prospective researchers can examine the impact of Customer Relationship Management (CRM) and Supply Chain Management (SCM) on the human resource's productivity in the COVID-19 era.Practical implicationsThe results of this research are applicable for all companies, their departments and human resources in the COVID-19 era.Originality/valueIn this paper, human resources' productivity in the COVID-19 era is pointed out. The presented new model provides a complete framework for investigating cloud-based enterprise resource planning systems affect the productivity of human resources in the COVID-19 era.


Sugarcane in Andhra Pradesh is one of the important commercial crops grown in a wide variety of soils from sandy loams to deep black soils. Soil fertility levels also vary from place to place, particularly soil phosphorus status, it was low in clay soils and medium to high status in clay loams and high status in sandy loam soils. As a consequence of high cost of water soluble chemically processed phosphatic fertilizers and poor P use efficiency due to fixation as insoluble phosphates, imbalance in NPK ratios are anticipated which eventually leads to reduced productivity of sugarcane. Continuous application of inorganic phosphate fertilizers along with available organic manures have accumulated residual available phosphorus exceeding levels needed for maximum crop International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 11 (2019) Journal homepage: http://www.ijcmas.com


The characteristics of propellant mixing near the injector have a profound effect on liquid rocket engine performance. Injector element geometry and propellant momentum are the only parameters available to control such mixing. A multiphase flow combustion model utilizing propellant real-fluid properties was developed to predict the mixing and thermal environment created by element configurations. The multiphase model was incorporated into a mature computational fluid dynamics code that can be used to simulate the flowfield near the injector and to analyze the combustion chamber and nozzle wall heating. The validity of the present model and code was investigated by comparing predictions to test data for two liquid oxygen/gaseous hydrogen unielement shear coaxial injector and two cryogenic nitrogen jet injection experiments. These simulations and those of several other investigators were critically compared at the 2nd International Workshop on Rocket Combustion Modeling. Based on these comparisons, it appears that the present model is a good, computationally efficient approximation of liquid rocket injector flows for both subcritical and supercritical spray combustion.

Modern mechanical applications are creating a demand for faster and more controllable means of coupling and decoupling motion. One interesting approach to this problem uses a peculiar blend of fluids and electrostatics.


Here we present a self-consistent, bimodal stationary solution for spherically symmetric flows driven by young massive stellar clusters with a central supermassive black hole (SMBH). We demonstrate that the hydrodynamic regime of the flow depends on the location of the cluster in the 3D (star cluster mechanical luminosity-BH mass-star cluster radius) parameter space. We show that a threshold mechanical luminosity (Lcrit) separates clusters that evolve in the BH-dominated regime from those whose internal structure is strongly affected by the radiative cooling. In the first case (below the threshold energy) gravity of the BH separates the flow into two distinct zones: the inner accretion zone and the outer zone where the star cluster wind is formed. In the second case (above the critical luminosity), catastrophic cooling sets in inside the cluster. In this case the injected plasma becomes thermally unstable, which inhibits a complete stationary solution. We compared the calculated accretion rates and the BH luminosities with those predicted by the classic Bondi accretion theory and found that Bondi's theory is in good agreement with our results in the case of low-mass clusters. However, it substantially underestimates the accretion rates and BH luminosities if the star cluster mechanical luminosity LSC ⩾ 0.1Lcrit.


/'_ /2* A numerical simulation of the process of formation of the c . terrestrial planets is carried within the framework of a new theory for the accumulation of planetary./ and satellite systems [1]. The numerical simulation permitted determining the parameters of the protoplanetary disk for which the three planets (Mercury, Venus and the Earth) are formed as a result of the evolution. The acquisition of a slow retrograde rotation for Venus was discovered during the course of investigation, whereas Mercury and the Earth acquired.direct rotation jabout their axes. Deviations of the semi-major axes of these three planets|as well as jtbe masses of the Earth and Venus from the true values are ;-l small as a rule (< 10%). It is shown that during the accumulation of the terrestrial planets, there existed a profound relationship between the process, of formation of the orbits and masses of the.planet and the process of formation of their rotation about their axes. Estimates are presented for the radii of the initial effective bodies and the time of evolution for the terrestrial accumulation zone. TABLE OF CONTENTS ' /_4


The hydrodynamic force between a spherical glass particle (radius ∼ 10 μm) and a smooth, flat glass plate in Newtonian silicone oil (viscosity, η ∼ 95 mPa s) was measured using the atomic force microscopy (AFM) colloidal probe technique and was compared to Reynolds lubrication theory. When the particle and plate were coated with a hydrophobic silane, the measured forces were consistent with Reynolds lubrication theory without the need to introduce the concept of a slip length. When the particle was hydrophilic, the results were more variable, sometimes being consistent with the no-slip boundary condition and sometimes being better fitted by invoking a constant slip length (up to 33 nm). The hydrophilic system was not well characterized because the hydrophilic solid may have entrained or attracted a layer of water (η = 0.001 Pa s) of unknown thickness, which would lubricate the flow and explain the apparent slip length. In addition, all AFM force measurements suffer from the problem that the solids occasio...


The aim of the research: to study pathophysiological mechanisms of adenomyosis development by determining the role of macrophages in the uterine microenvironment.
Materials and methods: a prospective study has been conducted on 35 women. There were 20 (57.1 %) who had adenomyosis of I degree. The control group consisted of 15 (34.3 %) gynecologically healthy women. The patients underwent general clinical, instrumental (ultrasound, hysteroscopy) examinations. Fragments of the uterine wall obtained by hysterorectoscopy were used for morphological study. The method of immunohistochemical determination of CD68+ and CD163+ macrophages was used to analyze the characteristics of phenotypic equivalents of M1 and M2 macrophages in uterine tissue samples.
Results: The increase in the number of macrophages in the myometrium of patients with adenomyosis revealed in this study, which is found in large numbers in the areas of infiltration of the stroma of myometrial cells in close association with the perivascular region, can be regarded as the basis of the mechanism for the formation of endometrioid heterotopia. Furthermore, distortion of the CD68/CD163 ratio of macrophages is characterized by proinflammatory shift.
Conclusions: The study's main result is an increase in the quantitative indicators of CD68+ macrophages associated with adenomyosis, which indicates an immunopathological process in adenomyosis.


Activities of NO decomposition and reduction with methane over Co{sup 2+} ion-exchanged ZSM-5 were evaluated. and the reaction mechanism was investigated. An initial 90% conversion of NO to N{sub 2} was achieved over Co-ZSM-5 at 450{degrees}C in a 2250 ppm NO-He gas stream, which is 100% higher than the current most stable and active Cu-ZSM-5 at comparable reaction conditions. Even at as low as 200{degrees}C, a 30% conversion of NO to N{sub 2} was observed. At least two different types of catalytic active sites were found to be present for NO decomposition in this catalyst: one appealed at ca 200{degrees}C, the other above 400{degrees}C. The catalyst which lost its decomposition activity remained active for NO reduction with methane, indicating a possible reaction mechanism in which Co{sup 2+} decomposes NO molecule, loses its activity, and is regenerated by intermediates of NO{sub 2} and CH{sub 4} reaction. A need for a different active site for NO reduction with methane cannot been eliminated. Studies of adsorbed species with TGA and Photoacoustic FT-IR will be reported.


The response of a magnetic field perpendicular to the interface on the Rayleigh-Taylor instability (RTI) is investigated when mass along with the heat is transferring through the interface. The fluids considered in this analysis are electrically as well as thermally conducting, viscous, and incompressible. The top-heavy system is considered in such a way that the liquid lies above its vapor. The governing system of nonlinear partial differential equations is linearized in the perturbed state. The well-known normal mode procedure is utilized and a critical value of wavenumber is calculated to determine the stability/instability of the interface. This wavenumber is found to be a function of fluid viscosities, heat transfer coefficient, fluid densities, etc. Various plots showing the effect of heat/mass transfer, magnetic field, etc. have been made and illustrated physically. We achieve that the transport of heat/mass at the interface reduces the amplitudes of perturbations.


The utility model discloses a pointer scale type replaceable safety cotton swab, which comprises a swab body and a cotton ball. The cotton ball is connected with the swab body. A measuring rod is provided with a slide rail. Scales are carved or printed beside the slide rail. A sliding pointer is inserted in the slide rail. One end of the measuring rod is hollow and the swab body is inserted in the hollow end of the measuring rod. Due to the adoption of the above structure, since the swab body is inserted in the measuring rod, the additional length of the swab body is increased. The length of the swab body itself can be greatly shortened. Therefore, the application amount of wood for producing the swab body is reduced, thus is beneficial to environmental protection and resource conservation. Generally, the length of an external auditory canal inside an ear is 2.5 to 3.5 cm. With the scales on the measuring rod as a reference, the sliding pointer is moved at the position of a scale within the safe distance. Therefore, the pointer scale type replaceable safety cotton swab provides a reference standard for the picking of ears. Ears are protected from being injured by people who do not have a good grasp of scale.


Externally mounted cellular antennas are often used in cars in conjunction with a phone handset. External antennas not only improve antenna system performance but also decrease radiation exposure to the phone user. The antennas for cellular phones can be roof-mounted, magnetically mounted or mounted on the glass of the vehicle. The glass-mounted antenna offers distinct advantages in that a hole does not need to be punched or drilled in the sheet metal of the vehicle nor does a cable have to be routed through a window or body panel opening. This paper presents a new geometry for the efficient coupling of multiple cellular bands (North American AMPS/PCS or European GSM/PCS/UMTS) through automotive glass. The new coupling geometry is of a small size and has a bandwidth on the order of 100% based on a 3 dB reduction from the peak coupling frequency. Dimensions of the coupler can easily be changed to shift the coupling response up or down in frequency. The frequency bands covered lie between 824 MHz and 2.17 GHz.


The extent of recent literature in cytogenetics conceals the fact that relatively few laboratories perform chromosome analyses as a routine procedure, and even fewer analyze populations of a size desirable for extraction of statistically valid information. A major deterrent is probably cost of time and money; and a minor one, possibly, the feeling that tissue culture techniques require highly specialized equipment and skill. In fact, the basic technique is quite straightforward and fully amenable, without loss of reliability, to simplification and economy. The method described here permits efficient study of large numbers of individual specimens with a minimum of effort, materials and equipment. Reagents. 1. Phytohaemagglutinin (PHA). a. Wash red kidney beans (Phaseolus vulgaris) in water. b. Grind in a pestle and extract overnight at 4°C in normal saline using 10 ml per gram of bean. c. Centrifuge to clear the supernate, sterilize by filtration and store frozen. 2. Medium. a. 80% Minimum Essential Medium Eagle (in its spinner formulation and with added glutamine) and 20% pooled human serum (outdated bank blood does very well). b. Add 50 units per ml of preservative free heparin and 0.2 to 0.5 ml of PHA per 100 ml. The amount of PHA varies with the strain of Phaseolus used and the concentration of the extract and should be ascertained for each batch. c. Dispense the medium with needle and syringe in 2 ml lots into nontoxic rubber stoppered, evacuated test tubes, and replace the vacuum with room or alveolar air using a needle and plastic tube containing cotton (those found in transfusion sets are quite satisfactory). Store frozen.

The paper summarizes the motivation for the work, the description of the facility, the tasks to be performed, the results obtained by the participants up today, and the conclusions.


This essay explores the relationships between the black (or near black) dress of men as depicted in late nineteenth-century French portraiture and the professional practices of tailoring and dyeing. Moving beyond issues of style and fashion it identifies semantic congruence between the material character of certain works on canvas and the technical processes of producing 'black' textile and turning it into clothing. Focusing on Edgar Degas (but discussing also work by Henri Fantin Latour, Carolus Duran and Edouard Manet) the author explains not only how the theories and practices of painting, dyeing and tailoring intersect and inform each other but also how artists creatively explored the defects -such as loss of colour, wrinkles and signs of wear- that evolving technologies in dyeing and tailoring sought to eradicate. In the black and white practice of photography, that Degas enthusiastically embraced towards the end of his life, was located the logical extensin to these proccupations. A medium as indexical as clothing itself, photographs could register the ways in which bodies imprinted into dress a unique material dimension that endured even as the body, like the black of its dress, faded.


The production of corn or soybeans for bio-based fuels and materials requires significant inputs of nitrogen (FN) and phosphorus fertilizer (FP) to increase grain yields. Approximately 50% of these nutrients are integrated into plant biomass. The remaining 50% is volatilized, leached into surface and groundwater, or transformed into gaseous species such as N2, NO, or N2O. Recent efforts to complete lifecycle inventories for bio-products based on corn, soy or corn stover feedstocks have largely ignored flows of fertilizer nitrogen and phosphorus to surface water bodies. The studies that have included nutrient leaching generally assume that a constant fraction of the fertilizer is leached, typically ~24-30%. This approach fails to integrate the very wide variability in leaching rates and, therefore, fails to adequately predict yearly variability in eutrophication and hypoxia.


While Hannah Arendt claimed to have abandoned her early conception of radical evil for a banal one, recent scholarship has questioned that conclusion. This article contributes to the debate by arguing that her conceptual alteration is best understood by engaging with the structure of norms subtending each conception. From this, I develop a compatibilist understanding that accounts for Arendt's movement from a radical to a banal conception of evil, by claiming that it was because she came to reject the foundationalism of the former for the non-foundationalism of the latter, where norms are located from an ineffable 'source' diffusely spread throughout the society. While it might be thought that this means that such norms are all-encompassing to the extent that they determine individual action, I appeal to her notions of plurality, action, and natality, to argue that she defends the weaker claim that moral norms merely condition action. This demonstrates how Arendt's conceptions of evil complement one another, highlights her understanding of the action–norms relation, and identifies that there is built into Arendt's conception(s) of evil a resource for resisting totalitarian domination.


Using HTDMAB with different dosages as the surfactant,the authors modified montmorillonites and then described their free swelling properties in water and toluene on the basis of free swelling ratio experiments.A careful analysis led to the discovery that the free swelling ratio of the modified montmorillonite tends to decrease in water but increase in toluene,and that when the dosage of surfactant is around 15%,the swelling ratio of modified clay is rather low no matter whether it is in water or in toluene.This means that only when the dosage of the surfactant is strictly controlled can the modified montmorillonite without water and oil affinity be prepared.This conclusion is also applicable to the reservoir core rocks,and hence the damages caused by the clay minerals swelling in the water and the superfluous oil molecules adsorbed on the surface of the minerals can be prevented beforehand.


Selogiri is one of the gold prospects in Indonesia. The deposit model is espected to be a porphyry coppergold deposits, which overprinted by low sulfidation epithermal gold quartz deposits. Geochemically, the calc-alkaline rocks from Selogiri range from primitive to relatively fractionated compositions, as reflected by SiO2, MgO contents and variable concentrations of the mantle-compatible elements (67–272 ppm V, 4–81 ppm Ni). These data are consistent with K2O contents, low average K2O/Na2O ratios (0.4), with some anomalous K2O/Na2O ratios (up to 50) and Ba/Zr ratios (up to 8.5), which indicate moderate potassic alteration. The concentration of copper and gold in the bulk-rock is low, Cu < 0.1% and Au < 0.1 ppm, respectively). Most economic porphyry Cu systems are characterized by multiple intrusions and repeated episodes of mineralizing hydrothermal activity, the Selogiri deposit formed during a single or up to two times intrusion periods. Therefore, the short period of hydrothermal activities in Selogiri did not reach an economic ore deposit.
