It has been well established that T cells exert a number of important regulatory effects on the activation of B cells by antigen. T helper (TH) a cells, for example, are required for the generation of antibody responses to the large class of T-dependent antigens (1-3). The complexity of such helper effects has been demonstrated by recent studies describing the existence of two distinct pathways of T-dependent B cell activation in these responses (4-6). These pathways differ in their requirements for major histocompatibility complex (MHC) -restricted cell interactions, in their requirements for covalent linkage of carrier and hapten, and in the identity of the B cell subpopulations which are activated (6). Thus, Lyb-5B cells are activated by a pathway requiring both MHC restricted Tn cell-B cell interaction and carrier-hapten linkage, whereas the activation of Lyb-5 + B cells is MHC restricted for T cell recognition of accessory cells only and requires neither restricted T-B interaction nor carrier-hapten linkage (6). Because at least two pathways exist for the T-dependent activation of B cells, it is of importance to determine whether these distinct pathways can be independently modulated by regulatory influences such as those exerted by T suppressor (Ts) cell populations. The present studies have been carried out in an effort to characterize the regulatory influences acting upon defined pathways of T cell dependent B cell activation. In these studies, it was first demonstrated that high concentrations of free carrier strongly inhibited the MHC-restricted in vitro responses of primed Lyb-5B cells, whereas in contrast these same concentrations of free carrier failed to inhibit the in vitro activation of Lyb-5 ÷ B cells. The inhibition of Lyb-5B cell responses by free carrier was shown to result from active suppression mediated by carrier-specific primed Lyt-1+2 T cells and to require the additional participation of unprimed Lyt1-2 + T cells. The activation of this suppression was antigen specific, whereas suppression, once activated, was antigen nonspecific in its effect.


The purpose of this study is to study the effect of ethics and religion on reducing corruption, moderated by the government's internal control system. This study used quantitative method. The population is Indonesian society. The research sample is the academic community and auditors. The sample selection is done purposively. The data used is primary data. Data collection was carried out using an online questionnaire. A total of 108 respondents filled out a questionnaire created using Google forms. The results showed that ethics had no significant effect on reducing corruption, religion had no significant effect on reducing corruption, moderating government internal control systems on ethical influence on reducing corruption was not significant, and moderating government internal control systems (SPIP) on religious influence on reducing corruption was not significant. Subsequent researchers are advised to use cultural variables as one of the independent variables.


Although the application of chemical fertilizers to crops promotes plant growth and yield, their continuous use affects soil heath and creates environmental pollution. On the other hand, plant biostimulants improve nutrients absorption, plant growth, yield and produce quality and are environment-friendly. Therefore, an experiment was conducted during 2021-22 to evaluate the effect of some biostimulants on the performance of the apple cv. Anna, planted in a sandy loam soil at Marsa Matruh governorate, Egypt. Ninety trees were randomly selected and sprayed with 4 or 6% moringa leaf extract (MLE), 0.3 or 0.4% seaweed extract (SWE), 1000 or 2000 mg L−1 Fulvic acid (FA), 4% MLE + 0.3% SWE + 1000 mg L−1 FA (combination 1), or 6% MLE + 0.4% SWE + 2000 mg L−1 FA (combination 2) before flowering, during full bloom and one month later and compared with a control (untreated trees). The results demonstrated that spraying MLE, SWE or FA or their combinations positively improved the vegetative growth, fruit set %, fruit yield and fruit physical and chemical characteristics as well as leaf nutritional status. The positive effect of MLE, SWE and FA was increased in parallel to an increase in the used concentration of each one of them. The highest increments in the measured parameters were accompanied by the application of combination 2 over the other treatments.

Simultaneous wireless information and power transfer (SWIPT) and interference alignment (IA) are two emerging techniques in energy harvesting and interference management for the next generation wireless networks, respectively. Although many studies have focused on SWIPT and IA, the conjunction of these two techniques is largely ignored, which should be noted to reuse the interference as energy for harvesting. In this paper, we jointly study SWIPT and IA in the multiuser MIMO system to realize energy harvesting and interference management simultaneously and effectively. Specifically, antenna selection (AS) based SWIPT scheme is proposed and analyzed for IA networks. Furthermore, power allocation (PA) for multiple data streams is designed to further improve its performance, and the closed-form solution can be obtained by Lagrange duality method. In addition, given the constrained number of antennas, another scheme called power splitting (PS) based SWIPT is utilized, where PA is also considered and formulated as a joint optimization problem. Simulation results are presented to show the superiority of the proposed schemes.


Objective To construct specific human nestin-shRNA expression vector and screen the stable transfected cell clone.Methods Different concentrations of nestin-siRNA(30,50,80 nmol/L) or control siRNA were used to transfect human melanoma cell line UACC903.After 48 hours,nestin expression was detected by immunofluorescence and RT-PCR.The lentivirus vector containing genes of down-regulating nestin expression and two enzyme sites of XhoⅠ-HpaⅠ was constructed and transformed into XL-10 Gold cells.Plasmid was extracted and sequenced to identify effective clone.Recombinant lentivirus was packaged and infected into UACC903 cells.Nestin expression in UACC903 cells was checked.Results Nestin expression in UACC903 was significantly down-regulated by special siRNA treatment as validated by immunofluorence,RT-PCR and Western blotting.Conclusion RNA interfering(RNAi) mediated by the shRNA vector can significantly down-regulate the expression of nestin in UACC903 cells.The stable transfected cell clone is obtained for further study.


Everyday consumers are bombarded with different advertising campaigns but they do not respond as they need something other than tangibles. There is need to explore something more than tangibles that can attract their attention. This can be done by using appropriate advertising appeal in the advertising campaign. If advertising appeal is interesting then it grabs the attention of the customers. For the present study survey method was used. It was done in two stages; in first stage initial questionnaire was prepared and implemented on 50 judges and after analyzing this data final questionnaire was prepared and was implemented on 200 respondents in the age group of 18-25 years. Findings of the study revealed that persuasiveness, distinctness, perfectness, fascinating, sensational, energetic, aesthetic, elegant and captivating were the factors that emerged for the advertising appeal and dimensions were energetic, sensational, persuasiveness, distinctness and captivating. Factor and dimensions were compared on the basis of gender. It was found that persuasiveness, perfectness, sensational factors and energetic, sensational and persuasiveness dimensions do not vary on the basis of gender as males and females both felt that these factors and dimensions were important but females perceived that distinctness factor and dimension and aesthetic factor is more important than males but for males fascinating factor was more important than the females.


Technology has come through code in the linguistic domain (programming language), which means that  there are opportunities for applied psychologists to help develop technology that contributes to an inclusive society. If this environment is optimally designed, people will become the best they can be in many practical areas, from education to sport and from art to care.


The aim of this study is to identify college students' conception regarding to volcanic phenomena. This study was possessed the conception profile of freshmen in volcanology using questions instrument about volcanology concept and making decision skills instrument test which created by the researchers. A descriptive quantitative approach was used, which included 32 physics students at Surabaya State University as the participants. The result indicated that the physics students have a little understanding about volcanology concept. From all questions provided, they answered correctly less than 50 % only. In line with this, their making decision skills need to be trained. Meanwhile, as science teachers must have a good understanding of this subject matter. Therefore it can be concluded that the evaluated geoscience learning curriculum for pre-service science teachers needs to be evaluated.


The paper examines the effect of numerical diffusion on multi-dimensional thermal-hydraulic analysis using three differencing schemes of convective terms in the transport equation, namely, (i) upwind differencing scheme, (ii) partial donor differencing scheme and (iiii) skew upwind differenc-ing scheme. Scheme(iii) were proposed to eliminate the numerical diffusion from which Scheme (i) suffers in a flow field with convective dominance and streamline-to-computational grid skewness. Five basic numerical tests, including momentum and scalar transport test problems in simple geometries, are carried out and predicted results with these schemes are compared. Through the tests it is confirmed that (1) Schemes (i) and (ii) produce serious diffusion for a case with the flow which cuts a computational grid with a large angle, (2) Scheme (iiii) is effective for the case and (3) none of the schemes can give satisfactory results in a transient test.

Teaching Higher Order Thinking Skills (HOTS) has its own challenges and need to be emphasized in the curriculum as it is one of the skills of the 21st century. HOTS is among six main characteristics of students who aspire Ministry of Education to succeed globally. The purpose of this study is to determine the need and willingness of teachers to develop HOTS in the teaching of science in primary schools. The initial analysis is carried out based on the protocol requirements interview involving 6 science teachers in six primary schools. The results showed that the willingness of teachers in the implementation and knowledge is not enough. Teachers are also not mastered the skills to integrate elements of higher order thinking skills in science teaching. Difficulty students understand the questions and the difficulty level teachers build high-level questions are identified problems faced by teachers. The interview data also shows teachers need guidance material or HOTS module is easy to use for teaching and learning in the classroom.


Because these coupling reactions require tailored purified pro-teins, purification of the target protein was required. Difficultiesassociated with obtaining a diversity of purified proteins, atime-consuming and labor-intensive process, have no doubtlimited the number of studies using functional protein arrays.


In the modern world, people face an explosion of information and difficulty finding the right choice for their interests. Nowadays, people prefer online shopping for their needs. Recently, the recommender system has become one of the key technology for the online purchasing system. The collaborative filtering technique has been extensively applied for the Recommender Systems. However, collaborative filtering is suffering from data sparsity, cold start problems, and inaccuracy problems. To overcome these problems, we propose a novel approach of the Matrix Distributive collaborative filtering with ensemble integration. The experimental results illustrate the increase in performance against the existing methods.


A straightforward synthetic route to enantiopure spiro[indole-3,3'-indolizidines] is reported. The key step is a Lewis acid promoted cyclization of a Na-tosyltryptophanol-derived oxazolopiperidone lactam in the presence of Et3SiH.


Applicability of a leaching method to measurement of a clearance level of tritium in concrete was investigated. Static leaching tests were performed for tritium doped concrete samples in water, and the fraction of leached tritium was determined as a function of leaching time. The fraction increased rapidly in initial few days. After 10 days, the rate of increment was slow down, and stopped after 30 days in which the leaching ratio was 95±3%. In the case of actual concrete samples obtained from Japan Research Reactor No. 3, the leaching behavior was the same as that of simulated samples. The radioactivity of tritium determined by the leaching method showed good agreement with that from heating method. The method to leach out tritium from concretes with water is considered applicable to the analysis of a clearance level of tritium.


Objective To investigate the relationship between nonalcoholic fatty liver disease (NAFLD) and abnormality of glycolipid metabolism. Methods Related parameters of glycolipid metabolism of 3647 cases with NAFLD and 6338 healthy persons (as control group) were analyzed. Results In total, 9,985 retired peoples were examined and 3647 cases were suffered with NAFLD. The prevalence rate was 36.5%.The body weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), cholesterol (TC), triglycerides (TG), alanine aminotransferase (ALT) and fasting blood glucose (FBS) of NAFLD group were significantly higher than that of control group. The prevalence rates of hypertriglyceridemia, hypercholesterolemia, combined hyperlipidemia, overweight, obesity, impaired fasting glucose (IFG) and diabetes mellitus (DM) were significantly higher in NAFLD group than in control group. Potential risk factors of NAFLD were analyzed with logistic regression, which were shown as follows: BMI (OR=1.785, p=0.000), TG (OR=1.712, p=0.000), FBS (OR=1.157, p=0.000), TC (OR=1.138, p=0.005), Height (OR=1.105, p=0.005), ALT (OR=1.013, p=0.000), DBP (OR=1.008, p=0.031). However, TSH (p=0.631) failed to be list in the statistical model. Conclusion The prevalence rate of NAFLD in retired people was high. NAFLD was associated with several related glycolipid metabolism parameters except for TSH.


Data on physical properties of grain are essential for the design of equipment for handling, aeration, and storage, as well as processing cereal grains and other agricultural materials. Basic thermal and moisture transport properties are also required for simulating heat and moisture transport phenomena during drying and storage. The most important such properties are the grain weight, sphericity, roundness, size, volume, shape, surface area, bulk density, kernel density, fractional porosity, static coefficient of friction against different materials and angle of repose, heat capacity, thermal conductivity, thermal diffusivity, moisture diffusivity, equilibrium moisture content, and latent heat of vaporization. These properties vary widely, depending on moisture content, temperature, and density of cereal grains. The experimental measurement of the physical and thermal properties of cereal grains is the concern of postharvest technologists and researchers. Substantial research has been carried out, over the years, on gathering data for material property evaluation, and some excellent review articles have been published in various scientific journals on the physical, thermal, and moisture transport properties of plant and animal food materials (Nelson, 1973; Polley et al., 1981; Miles et al., 1983; Sweat, 1974). Several excellent books have also been published highlighting data on physical, thermal, chemical, and electromagnetic radiation properties of food and agricultural products cov-


Laboratory small-scale physical models and non-contacting ultrasonic techniques are used to tackle theoretical or methodological issues of seismic wave propagation and seismic methods. Literature shows a wide range of experiments, both in terms of materials used for the production of the physical models but also regarding the models geometry and the recording techniques, which are chosen according to the issue that is being addressed. With a proper choice of granulometries and deposition processes, we managed here to create a two-layer granular physical model with a relatively complex geometry and characterized by 2D structures, property contrast and velocity gradients within layers. We performed several small scale seismic acquisitions using a mechanical source and a laser vibrometer. The acquired seismograms were interpreted by applying the surface-wave method and by extracting P-wave refraction data. We managed to correctly reconstruct the geometry of the model and estimated the parameters controlling the velocity gradients of P and S waves for both layers. The results we got are coherent with the different compaction degree we obtained for the two layers and with previous studies conducted over similar media.


In most existing simulators, the outputs of a simulation run consist either in a simulation report generated at the end of the run and summarizing the statistics of interest, or in a (set of) trace file(s) containing raw data samples produced and saved regularly during the run, for later post-processing. In this paper, we address issues related to the management of these data and their on-line processing, such as: (i) the instrumentation code is mixed in the modeling code; (ii) the amount of data to be stored may be enormous, and often, a significant part of these data are useless while their collect may consume a significant amount of the computing resources; and (iii) it is difficult to have confidence in the treatment applied to the data and then make comparisons between studies since each user (model developer) builds its own ad-hoc instrumentation and data processing. In this paper, we propose OSIF, a new component-based instrumentation framework designed to solve the above mentioned issues. OSIF is based on several mature software engineering techniques and frameworks, such as COSMOS, Fractal and its ADL, and AOP.


Pausinystalia yohimbine has been used for the treatment of sexual side effects caused by some antidepressants, as a blood pressure boosting agent, for dry mouth, and for nervous system dysfunction. Twenty adult male wistar rats weighing between 150g to 200g were used in this research to determine the effects of Pausinystalia yohimbe on the histology of kidney. They were divided into five groups; A, B, C, D and E of four rat each. Group A served as control and was fed with feed and water only. Groups B, C, D and E were administered with extract of Pausinystalia yohimbe at a daily dose of 3mg/kgbw, 5mg/kgbw, 7mg/kgbw and 9mg/kgbw respectively for 21 days. At the end of the experiment, the animals were sacrificed by cervical dislocation after anaesthetized with chloroform. The organ of study (kidney) was harvested and sections cut for histological preparation using H and E staining method. Results showed poor perfusion of renal tissue with moderately to severe damage of renal architecture indicating severe fatty change, tubular necrosis, depletion of glomeruli, moderate clumping and distortion of renal architecture and intra renal hemorrhage in all the experimental groups. The severity was more in groups D and E indicating that Pausinystalia yohimbe is capable of causing renal damage in a dose dependent manner


Pain is often poorly recognised and remains under-treated in older patients, especially those who are unable to articulate their discomfort. In those with severe cognitive impairment or communication difficulties, recognition of the non-verbal manifestations of pain is needed to ensure patient comfort. Understanding how likely these patients are to have pain, how we improve recognition of the signs of discomfort, and encouraging doctors to think about prescribing analgesics will allow these patients to retain their dignity, and reduce their physical and psychological distress during their inpatient stays.

 Over two periods in 2019–2020, pre and post introduction of Abbey Pain Scale. Inpatients on a HCE ward >65 years old Diagnosis of dementia and/or delirium Review of pain scores on the observation charts, analgesia and documentation of sources of pain.

 75 patients were reviewed, 39% with delirium, 45% with dementia Pain was often not considered during medical assessments, even if patients had presented with a fall 56% had a potential source of pain identified either in their medical or nursing notes, however there was disparity between these The majority of sources of pain were chronic joint issues or injuries sustained from falls Patients had their observations checked 2–4 times/day. A pain score was entered 56% of the time and less frequently in: diabetics (due to chart layout), long-stayers and those who refused their observations Use of the Abbey Pain Scale made no significant difference.

 (s). Disparity between notes highlighted a gap in communication. There is a risk of complacency with long-staying patients. Ketone readings are recorded over the pain score area on the observation charts, this needs to change. Refusing observations may be a sign of pain and staff should be more vigilant in these cases. A more integrative tool to monitor pain is required.


Ipomoea carnea is rapid growing weed species found in many continents including America, Asia, Africa and Australia. Proximate chemical analysis was performed by TAPPI standard method reveals that Ipomoea carnea contains holocellulose (67.49%), pentosan (16.70%), lignin (18.08%) and ash (6.14%). A good amount of holocellulose in Ipomoea carnea can be converted into fermentable sugars for generation of biofuel. Bioconversion offers not only a cheap and safe method for disposal of such weeds, but it also has the potential to convert lignocellulosic wastes into usable forms such as fermentable sugars that could be finally used for ethanol production. Conversion of cellulose into sugars is done with the help of enzymatic hydrolysis. The yield of sugars can be improved by using different types of pretreatment of the substrate. These include physical pretreatments and chemical pretreatments. Sometimes combining two or more types of pretreatments increase the yield. In the present work, sodium hydroxide pretreatment was used for hydrolyzing the Ipomoea carnea into fermentable sugars. The chip form of Ipomoea Carnea were delignified with 1%, 3%, and 5% NaOH and then commercial cellulase enzyme pretreatment was used. Scanning Electron Microscopy analysis showed that significant changes occurred in the structure of Ipomoea carnea after pretreatment, which is favourable for the hydrolysis and saccharification. The maximum fermentable sugar (202.38) µgm/ µl was obtained with 3% NaOH at 50 0 C after


Nucleic acid molecules modified to enhance recombinant protein expression, e.g., that of AF peptide binding antibodies, and/or to reduce or eliminate mis-spliced and/or intron read-through (IRT) by-products are disclosed. The invention also provides methods for producing AF peptide binding antibodies devoid of mis-spliced and/or intron read-through by-products by expression of such nucleic acid molecules under cell culture conditions suitable for recombinant AF peptide binding antibody expression.


A highly sensitive method for the quantitative determination of a potential antiarrhythmic drugs in the blood plasma has been developed. The method is based on the electron spray ionization/mass spectrometry (ESI-MS) techniques without preliminary chromatographic separation and makes use of nibentan as the internal standard. A linear relationship between drug concentration and the peak intensity of ions of the analyzed substance (m/z = 398) and the internal standard (m/z = 382) is established. The detection limit is 3 ng/0.5 ml. The method is linear from 3 to 25 ng/0.5 ml with a correlation coefficient of 0.98. The coefficient of variation was less than 7 %.


We have developed a new fish tracking system using a synchronising method. The system consists of an ultrasonic pinger, four hydrophones, a four channel receiver, an 8-bit single board computer with ADC, a personal computer, an electronic magnetic compass and a DGPS receiving system. In this system, the bearings of the pinger are calculated using the short base line by measuring the receiving time differences of a pulse between channels. The distance from the hydrophone to the pinger is calculated by using an original method, in which the receiver and the pinger are syn-chronised to measure the interval between received pulses. A Synchronising drift error which accumulates with time is corrected by using the distance calculated from the transmission loss. This method gives a more accurate measurement of distance. Using this system, we successfully tracked three striped jack Caranx delicatissimus for five days.


Abstrcat According to design standard of water power, the optimal water diversion flow rate was determined based on the maximum water energy utilization analysis. It was shown that the determined installed capacity is reasonable by the method, which could eliminate impacts caused by man.

This is a documentary, retrospective research with a quantitative approach. Data were collected using a form containing the variables: month of hospitalization, type of abortion, reason for hospitalization, procedure performed, age, marital status, origin, occupation, obstetric history and gestational age. Women in an abortion situation sought the service with missed abortion, presenting pain in the lower abdomen and transvaginal bleeding, and curettage was performed. . The age of these women was concentrated in the age group of 20 to 39 years, married, of the researched municipality, dealing with domestic affairs, with number of pregnancies between one and two, were experiencing abortion for the first time and early.


We measured the electric resistance of KxFe2-ySe2 which is said to have two SC dome. The measurement was performed at 1-14 GPa and at low temperature down to 1 K and the samples have different states of Fe-vacancy by annealing. From results of the measurements, we observed SC-like behaviour at over 11 GPa. The behaviour at higher temperature than Tc indicates that there are two SC phases.


Developments in drug law and policies In preparation of the new Dutch drug policy white paper, the Dutch drug policy of the past thirty years has been evaluated, and a 'drug risk ranking' study and a risk assessment of cannabis were performed. These studies aimed to support the Advisory Committee on Drugs Policy, which made recommendations for improvements to drug policy, as requested by the Minister of Health, Welfare and Sport, the Minister of Justice and the Minister of the Interior and Kingdom Affairs. Following publication of these reports on 2 July, 2009, a letter outlining Dutch drug policy was published on 11 September 2009 taking the recommendations of the Advisory Committee into account. The most important proposals for changing the drug policy are: use of drugs and alcohol by minors must be tackled far more rigorously; coffee shops should become points of sale for local users only; more consistent measures against organized crime are needed. The classification system used in the Opium Act will be reviewed. This proposal will be discussed in the first quarter of 2010 in the House of Representatives, before a more comprehensive policy document will be drafted. On 1 December 2008 all hallucinogenic mushrooms were put on Schedule II of the Opium Act.


Aim: This research work investigated the bioaccumulation of metals in selected edible vegetables from the soils on which they were grown. Place of Study: Two (2) different study locations were chosen from Etsako-West Local Government Areas of Edo State of the Federal Republic of Nigeria. Etsako-West Local Government Area has an area of 660 km2 on Latitude 7.0878oN and Longitude 6.5010oE with the headquarters in Auchi. Methodology: Leaves of fluted pumpkin (Telfairia occidentalis), African spinach (Amaranthus hybridus) and water leaf (Talinum triangulare) and soil samples were randomly collected from Water Board and Iyerekhu farms in Etsako-West Local Government Area, Edo State, Nigeria and were analysed for their elemental compositions, using X-ray fluorescence (XRF) technique. Original Research Article Oladebeye et al.; JSRR, 26(2): 27-37, 2020; Article no.JSRR.55000 28 Results: In both soil and plant samples, silicon (Si) were most abundant, ranging between 18.85 and 38.91%. The decreasing order of abundance of elements in the plant samples was Si>K>Ca>Al>Cl>S>P>Mg>Fe>Ti>Mn>Zn>Sr>Cr. Toxic heavy metals such as As, Pb, Co, Cd and Cu were not detected in both soil and vegetable samples. The concentrations of the elements in the samples were higher than the permissible limits of WHO/FAO and EU for soils and plants, except Zn in the soil samples and Talinum triangulare from Iyerekhu farm. The peak transfer factor, 238.43 was obtained for K in Talinum triangulare from Iyerekhu farm while the least is 0.00 for Zn in all the plant samples. The overall mean ability of plant to absorb elements from the soil was most with Talinum triangulare, followed by Amaranthus hybridus. Conclusion: The vegetables studied had high tendency to bioaccumulate the bioavailable metals in soils. However, all the vegetables studied, especially T. triangulare could be used in phytoremediation of polluted soils.


Countries may face debt problems for periods when the long-run solvency condition about current account deficits holds. Using Markov Switching model, the econometric methodology proposed in this study allows us to distinguish periods that are associated with unsustainable outcomes from those in which the solvency condition holds. Analyzing Turkey's current account deficits between 1987:4 and 2010:4, it is found through defining three regimes that probability of persistency in the sustainable path is 0,696 whereas the probabilities of transition to the crisis path and to the unsustainable path from the sustainable path are 0,125 and 0,178 respectively. Also, Turkey seems to be in a crisis regime since the first quarter of 2010. This may be an informative alert for the Turkish economy about oncoming balance of payments crisis in a year.


The trace medicine metabolites in some hospital wastewater during treatment process were determined and charactered by gas chromatography - mass spectrometry. Analysis results identified the present of various polycyclic and heterocyclic refractory compounds in the hospital wastewater. This study indicated the medicine metabolites could not be effectively removed by the traditional treatment process, and it was irradiative for the technology improvement in the wastewater treatment plants receiving hospital effluents.

We study the evolution of non-linear circularly polarised Alfven waves by solving numerically the time-dependent equations of magnetohydrodynamics (MHD) in one dimension. We examine the behaviour of the waves and find that different physical mechanisms are relevant in different ranges of β . In a low β plasma the wave may undergo a parametric decay. This is because the wave excites a density enhancement that travels slower than the wave itself and thus interacts with the wave. When $\beta \ge 1$ the density enhancement does not interact with the wave and no decay takes place, instead the Alfven wave is reflected against the density enhancement. The reflection zone propagates with the speed $\frac{1}{n} \, v_{\rm A}$. Because of that the magnetic flux is conserved which results in an amplification of the oscillating magnetic field by a factor $\frac{1}{n}$. We find that n depends on  β , and that in particular it is ≤ 1 for values of $\beta \sim 1$ and ≥ 1 for $\beta \gg 1$. We discuss the relevance of these mechanisms to the acceleration of the solar wind, and the triggering of MHD turbulence in the polar wind region. In particular these simulations can explain the presence of inward propagating Alfven waves in the solar corona.


HIDRADENITIS suppurativa is a chronic, recurrent, indolent, suppurative infection of the apocrine glands of the axillae, areolae of the breast, inguinal regions, external genitalia, and perianal areas. The early lesion resembles a furuncle without a necrotic core. Later in the disease, subcutaneous abscesses, fistulas, intercommunicating sinus tracts, and irregular hypertrophic scarring are seen. The loose areolar tissue present in the involved sites facilitates the burrowing characteristic of the disease. This disease occurs equally in both sexes at or after puberty. Menstrual and premenstrual exacerbations have been reported.1Axillary involvement is more common in females; the perianal involvement is more frequent in males. One in six patients with axillary involvement has perianal lesions; however, only one in 13 cases of this disease has only perianal involvements.2 Brunsting3emphasized the association of hidradenitis suppurativa with acne conglobata and dissecting cellulitis of the neck and scalp. He pointed out that

The MERL 76 alloy was developed to produce components by hot isostatic pressing. To provide for enhanced shaping capability, improved material utilization, and to explore potential property benefits, Pratt & Whitney embarked on a development program to qualify Gatorized@ MERL 76. The MERL 76 composition was fixed, and billets were consolidated by hot isostatic pressing (HIP), followed by Gatorizing@ into the required component shape. Detailed studies were conducted to define both metal processing (e.g., HIP and forging) and heat treatment parameters. Comprehensive monotonic and fatigue testing of full-size components has demonstrated that Gatorizeda MERL 76 met all program goals. This material has been used in commercial service since 1983, with excellent experience. Superalloys 1988 Edited by S. Reichman, D.N. Duhl, G. Maurer, S. Antolovich and C.

Abstract During the late 1890s and early 1900s, psychologists began to study the motor skills of athletes. One individual who gained attention for his work related to investigating the motor skills of athletes was Walter R. Miles. In particular, his research related to the reaction time of football players at Stanford University gained notoriety. Although these studies have been overviewed, discussion of Miles's additional work and influence related the study of athletes has received virtually no attention. This paper examines the various contributions of Miles and his colleagues to the study of the perceptual and motor skills of athletes.

A new approach to account for finite thermal conductivity and turbulence effects within atomizing liquid sprays is presented in this paper. The model is an extension of the T-blob and T-TAB atomization/spray model of Trinh and Chen (2005). This finite conductivity model is based on the two-temperature film theory, where the turbulence characteristics of the droplet are used to estimate the effective thermal diffhsivity within the droplet phase. Both one-way and two-way coupled calculations were performed to investigate the performance of this model. The current evaporation model is incorporated into the T-blob atomization model of Trinh and Chen (2005) and implemented in an existing CFD Eulerian-Lagrangian two-way coupling numerical scheme. Validation studies were carried out by comparing with available evaporating atomization spray experimental data in terms of jet penetration, temperature field, and droplet SMD distribution within the spray. Validation results indicate the superiority of the finite-conductivity model in low speed parallel flow evaporating spray.


. This study uses a causality research design, which analyzes the causality relationship between research variables in accordance with the hypotheses compiled. The research data will be analyzed using a statistical tool, the Grenger causality test with the help of Eviews 9.0. Grenger's causality test is a method to find out a dependent variable (dependent variable) can be requested by the independent variable (independent variable) and on the other hand the independent variable can be determined the position of the dependent variable. The purpose of this research is to refute theories or hypotheses to support or oppose theories or hypotheses of the results of previous studies The variable minimum wage has a positive effect on labor supply with a coefficient of 0.727046.


Popular support is essential to the long-term survival of all political systems, yet the question of what affects citizens' faith in their political institutions remains debated. We construct a new measure of institutional trust for 130 countries between 1990 and 2017 and use it to evaluate two important theories of regime support: a procedure-based theory that emphasizes the adoption of democratic and rule-based institutions, and a performance-based theory that focuses on governments' effectiveness in delivering concrete and essential public goods. We find strong evidence that performance dominates procedures: Citizens report greater trust in their political systems when the government can achieve rapid economic growth, low unemployment, and domestic stability. However, just having "good" liberal democratic institutions alone does not seem to improve regime support. These findings have important implications for understanding the challenges currently faced by many democracies and the apparent resilience of some non-democracies.


A formation control method for multiple Unmanned Aerial Vehicles (UAVs) is proposed in the paper. The global information and local information are combined in the method. The global information is mainly composed of the expected flight trajectory from flight tasks and expected formation. The local information is mainly composed of the relative distance between vehicles, especially comparing to the expected formation configuration. Combining the global and local informations, a formation control method based on the guidance points is improved, and the compact formation keeping performance is enhanced, especially during some maneuvers(such as turning). The performance of the proposed method is verified through simulation results.


Abstract Infrared scintillation measurements were obtained along a 7-km path over San Diego Bay concurrently with meteorological measurements obtained from a buoy at the midpoint of the path. Bulk estimates of the refractive index structure parameter were computed from the buoy data and compared with scintillation-derived values. The bulk estimates agreed well with the scintillation measurements in unstable conditions. In stable conditions the bulk estimates became increasingly higher than the scintillation values as the air–sea temperature difference increased. This disagreement may be due to enhanced wave-induced mixing of the lower atmosphere that decreases the vertical temperature and humidity gradients in stable conditions from the assumed Monin–Obukhov similarity (MOS) theory forms, resulting in bulk values that are too high. The bulk estimates decrease rapidly when the absolute air–sea temperature difference approaches small positive values. These predicted decreases in were not observed in either ...


Pavement marking retroreflectivity depends on several factors including but not limited to the type of retroreflective optics, binder, installation quality, marking condition, and measurement type/geometry. Texas A&M Transportation Institute (TTI) evaluated the retroreflectivity of 19 pavement marking panels, prepared with different types of glass bead at standard 30-m and non-standard measurement geometries. The non-standard geometries represented typical commercial airplane configurations. The primary purpose of the research was to evaluate the effects of the glass bead refractive index (RI) (1.5 versus 1.9) and the measurement geometry on pavement marking retroreflectivity. Results showed a decrease in retroreflectivity with an increase in observation and entrance angles for both 1.5 and 1.9 RI. The study showed higher retroreflectivity levels for high RI beads at all the geometries evaluated. The result showed that 1.9 RI beads exhibit an average of 171% (862 mcd/m2/lx) higher retroreflectivity at standard 30-m car geometry as well as 102% (193 mcd/m2/lx) higher retroreflectivity at airplane geometry compared with 1.5 RI beads. The study found that an increase in bead RI had a larger effect on retroreflectivity than did an increase in bead size. The effect of the measurement geometry on the retroreflectivity level of the markings highlights a limitation of using the 30-m car geometry to represent the visibility of markings from a pilot's perspective. Additional work should be conducted to better assess the visibility of markings from various vehicle platforms and how to best represent the visibility through retroreflectivity measurement.


In the evolution of IC package, the primary trend is regarded to be the upgrading from planar 2D integration to 3D stacking. But before stepping into 3D IC category, a transitional generation called 2.5D is proposed. Due to the extremely fine pitch of modern IC, the IC substrate is difficult to match due to the incomparable line width/space. Therefore, a silicon interposer is introduced to fulfill the requirement of circuit re-distribution. In this paper, a package structure contains Si interposer to meet the demand of smaller and thinner form factor is proposed. The interposer is embedded into substrate by means of dielectric material lamination rather than solders joining and flip chip bonding. The embedded packaging technology is an integration of embedding active and passive components in built-up substrates and printed circuit boards (PCB). It can also be regarded as a process integration of PCB substrate and silicon substrate that raised the package density and miniaturized the package volume. In this investigation, an 8 inch thinned wafer was used as the test vehicle. Through silicon vias (TSVs) for interconnection could be produced either by deep reactive ion etching (DRIE) at wafer-level or by laser drilling at chiplevel. Meanwhile, Si chips were interconnected to the Si interposer to form an integrated 2.5D module. Afterwards, the 2.5D module was embedded by laminating a dielectric layer on both side of the module. Subsequently, the UV laser was used to form blind vias on the dielectric layer, and the chemical processes including de-smear, seed layer coating, Cu plating were applied to form the circuits or the BGA pads on the top or the bottom surface of build-up layer to connect the circuits of the 2.5D module. After circuit forming, the dielectric layer was fully cured at 170°C to enhance the adhesion between the Cu trace and the dielectric material. With this architecture, the thickness of interposer in a 2.5D-SiP could be subtracted, and the electrical performance should be improved because of a shorter signal transmission route. The feasibility of the packaging structure has been verified. The reliability is assessing by preconditioning, and the results were also discussed here.

We report room temperature ferromagnetism (RTFM) in Co-doped ZnO (Zn1−xCoxO; x = 0.01 − 0.05) powder synthesized using a co-precipitation method. Our magnetometry data reveal a weak FM behavior at RT in the range 0.01 < x < 0.05. FM by magnetic FM moment steadily decreases with increasing dopant. The O K-edge near-edge X-ray absorption fine structure (NEXAFS) spectra indicate that O vacancies increases with increasing Co concentration and that the sample with x ≥ 0.03 has more broadening at 535 and 540 eV, which may be due to the oxygen vacancies. Co in the ZnO host reveals a +2 oxidation state via the K edge NEXAFS spectra.


Abstract Infectious bronchitis, a major challenge to the global poultry industry, is an acute and highly contagious disease of the respiratory and urogenital tract of chickens which causes significant economic losses to poultry producers. In addition, Mycoplasma gallisepticum (MG) is another respiratory pathogen that remains a concern to producers. This study investigated the sero-prevalence of IBV and MG in commercial chickens in Ga-East district of the Greater Accra Region, Ghana, using sera obtained from 440 broiler and layer chickens showing no signs of disease. IBV and MG specific antibodies were determined using commercial ELISA kits. Majority (85%) of the samples tested positive for at least one of the 2 pathogens investigated, with 30% testing positive for both. Overall sero-prevalence of IBV and MG were 85.5 and 29.5% respectively suggesting a higher IBV than MG field challenge in the study area. IBV prevalence was significantly higher in layers (100%) than broilers (42%). Age of bird had a significant influence on IBV prevalence among broilers. The MG prevalence in layers and broilers were 39.4 and 0% respectively. This data supports the need to institute control measures to mitigate IBV associated losses and improve poultry production in Ghana.


A pillow assembly includes a top and bottom panel joined together to provide a pillow having an inner cavity accessible through an end opening formed with a closeable fastener. A scoop element is tethered to the pillow and is used to fill the cavity with on-scene shiftable, granular material such as sand, following which the scoop element is stowed within a pocket formed on the outer face of the pillow bottom panel. One or more other pockets on the bottom panel allow stowage of personal articles. In use, a person's head is comfortably supported atop the pillow while the granular material within the pillow shifts to accommodate the scoop element and other articles within the pockets.


A lighting device for a ventilator comprises a lighting module for holding lighting units and a power supply box module for holding a direct current supply for supplying power to the lighting units, wherein inversion proof structures enabling the lighting units to be mounted in one direction are arranged on the lighting module and the power supply box module. The lighting device has the advantages that the mounting is convenient, the condition of lighting unit inversion is avoided, and the brightness of light irradiating into the room by the lighting units is ensured.


Kinetic energy distributions of alkali-metal atoms (sodium and rubidium) desorbed from poly-dimethylsiloxane coated glasses via visible (532 nm) and near-infrared (1064 nm) laser irradiation are determined. In each case the time-of-flight spectra show a single desorption peak. In the case of sodium the mean kinetic energy of the desorbing atoms depends on the photon energy and linearly on the laser fluence. Evanescent-wave desorption measurements show that the origin of the desorbed atoms is within the bulk of the thin organic film. The results are discussed in terms of electronic excitation and resonant heating, providing values of barrier heights for desorption from PDMS. The observed small barrier heights explain the weak light intensity necessary for light-induced atomic desorption from such systems.


The present research work scope is in the area of intelligent static robotic supported by multisensor data fusion and integration. The usage of multisensor systems allowed the emergence of new research areas and further development of current areas. Automatic target recognition, mobile robot navigation, aircraft navigation, industrial tasks such as assembly, burnishing and trimming are typical multisensor system applications. In these cases, multiple sensors are not only advantageous but they are essential to their implementation. This thesis describes an experimental system for the acquisition of a surface profile using techniques of multisensor data fusion. This system is composed by the following elements: a PUMA 560 manipulator, which function is the positioning of the sensors mounted on the wrist flange of the robot, in order to acquire the surface profile; a controller area network (CAN) used for data acquisition and some basic control; ultrasonic sensors and a video camera. For this research project the following studies and tasks were carried out: 1) Evaluation of the features and performances of the PUMA 560 manipulator and its controller, which was replaced due to its limitations for this work. In the new architecture a PC performs the control of the PUMA. The inverse and forward kinematics routines were implemented and corrected. A few instructions were also implemented for simplifying some tasks of the robot. 2) Study of a CAN protocol based network and the interface with the ultrasonic sensors. The protocol for the application level was implemented. 3) Study and implementation of image processing techniques for dominant points extraction from the object contour. The goal of these techniques is to limit the robot working area. 4) Study of the problem of ultrasonic data significance, which required the adoption of a new model for the sonar sensors. 5) Study of the multisensor data fusion and integration techniques. The average, fuzzy logic, Kalman filter and heuristic methods were implemented. The most important results obtained were: a new model for ultrasonic sensors was adopted; different techniques for multisensor data fusion and integration were used and in particular an implementation of a fuzzy "arbitration" method. As a result, it was possible to perform the acquisition of a surface profile that was represented in a surface map. 1.

The position detection of overlapping area in the interframe for image stitching using auto and cross correlation function (ACCF) and compounding one image with the stitching algorithm is presented in this paper. ACCF is used by autocorrelation to the featured area to extract the filter mask in the reference (previous) image and the comparing (current) image is used by crosscorrelation. The stitching is detected by the position of high correlation, and aligns and stitches the image in shifting the current image based on the moving vector. The ACCF technique results in a few computations and simplicity because the filter mask is given by the featuring block, and the position is enabled to detect a bit movement. Input image captured from CMOS is used to be compared with the performance between the ACCF and the window correlation. The results of ACCF show that there is no seam and distortion at the joint parts in the stitched image, and the detection performance of the moving vector is improved to 12% in comparison with the window correlation method.


Evolutionary design refers to the use of evolutionary computing methods in the design process. Normally, this entails the formulization of the design problem as an optimization problem, which is solved using evolutionary techniques such as a genetic algorithm or particle swarm optimization. This paper provides three examples in the use of this highly effective method to the design of electromagnetic and electromechanical devices.


Simulation of RF circuits often demands analysis of distributed component models that are described via frequency-dependent multiport Y, Z, or S parameters. Frequency-domain methods such as harmonic balance are able to handle these components without difficulty, while they are more difficult for time-domain simulation methods to treat. In this paper, we propose a hybrid frequency-time approach to treat these components in steady-state time-domain simulations. Efficiency is achieved through the use of the multi-interval Chebyshev simulation method and a low-order rational-fitting model for preconditioning matrix-implicit Krylov-subspace solvers.


Millimeter-wave (mmWave) and ultra-dense networks are two key technologies for the fifth-generation (5G) and beyond communication system. However, the ultra-dense deployment of small base stations (SBSs) might introduce severe interference to users that connect to SBSs. This paper analyzes the performance of 5G communication networks where the SBSs with coordinated beamforming, operating at mmWave frequency band and macro base stations (MBSs) operating at sub-6 GHz coexist. First, by utilizing a stochastic geometry approach, we obtain the cell association probability expressions in terms of different cell association biases, base station density ratios and probabilities of line of sight (LoS) link. Furthermore, we propose a clustering method to choose some SBSs to eliminate intra-cell interference. Then, we put forward an average distance from the Kth SBS to a user to obtain signal-to-interference-ratio (SINR) and rate coverage probability expressions. The simulation results validate the correctness of the expressions, and indicate that the optimal cardinality of coordinated SBSs increases with the density of SBSs. In addition, the relationship between the cluster size K and the average energy efficiency is obtained, which can be used to guide the coordination principle in 5G and beyond communication systems.

Background and Purpose. All students enrolled in physical therapist (PT) graduate programs are required to complete full‐time clinical internships. The internships are synchronized so that all students in a cohort are off campus at the same time and are isolated from sharing learning experiences with their fellow classmates. The purpose of this project was to describe the development implementation and evaluation of a Web‐based program that supports student learning and critical‐thinking (CT) skills during PT students' clinical internships. Method/Model Description and Evaluation. Eighty‐one PT master's degree students across all levels were divided into 2 groups. Thirty‐nine students participated in the online program during their internships and 42 students completed their internships without participating in the online program. Participating students enrolled in an online component of their internships using WebCT. The course outline provided 4 areas of participation, including directed threaded discussions, a weekly e‐journal, 2 open bulletin boards for questions, and weekly "live‐chat" office hours. Students were required to participate in threaded discussions focusing on subjective assessment, ethical practice, and time management, and were expected to make a PT case presentation to their fellow students online. Assignments were designed to facilitate CT skills. CT skills were measured before and after the internships using the California CT Skills Test (CCTST). A post‐internship survey was also administered to both groups to assess communication with classmates during the internships and effectiveness of the online program. Outcomes. Sixty‐four percent of students participating in the online support program felt the program was beneficial in that it allowed communication and interaction with classmates across different levels of the program. The free discussion areas for student issues and treatment ideas received the most postings with 70 and 90, respectively. Seventy percent of the students felt the weekly e‐journal was a beneficial source of reflection. Eightytwo percent averaged an hour online per week, and 77% found WebCT easy to use. There were no significant differences in CT skills before or after the internships between the online and nononline groups. Participating students recommended dropping required postings in favor of free discussion areas due to the stress and constraints of their internships. The instructor/academic coordinator of clinical education (ACCE) found the e‐journals and student discussions aided in an awareness of problems occurring in the clinic facilitating mid‐term visits and conflict resolution. Discussion and Conclusion. Students benefited from access to their classmates and professor using online technology during their clinical internship, resulting in a positive learning experience for the students. The online program did not appear to effect students' CT skills. Offering students a virtual environment to communicate questions and concerns with the professor and classmates during their clinical internships may benefit both the students and the professor.


Consider a system of two queues in parallel, one of which is M/M/1 single-server infinite capacity queue, and the other M/M(N)/K batch service queue,where batch size N ≧ 2 and K < ∞. In the network, a stream of Poisson arrivals choose which queue to join, after observing the current state of the system, and so as to minimize their own expected delay. We show that a user optimal policy exists, and that it possesses various monotonicity properties. In addition, we give examples where state-dependent routing mitigates the Downs-Thomson effect observed under probabilistic routing.

ABSTRACT This article provides an overview of the genesis, development, and features of ScanGrants, , the free online resource, and discusses how librarians can develop inexpensive Web development projects that take advantage of the searching and categorizing skills they possess. This paper also touches on matters of copyright and the marketing of Web services outside of one's own institution and the importance for medical librarians to forge alliances with other institutional colleagues.


Objective To investigate the changes of surfactant associated protein A (ST-A) concentration inBALF and its relatiomhips with pulmonary injury after blast injury and blast injury combined with hypoxia. MethodTotally 131 Wistar rats (purchased from animal center of research Institute of Surgery, Daping Hospital, ThirdMilitary Medical University) were randomly divided into four groups: blast injury group ( BI group), blast injurycombined with hypoxia group Ⅰ (BAg Ⅰ group), blast injury combined with hypoxia group Ⅱ (BA Ⅱ group) andnormal control group. After blast injury was made by KST - Ⅰ bio-shock tube, rats of BA Ⅰ and BA Ⅱ groups wereput into hypoxia cabins immediately, where gas mixtures of 12.5% and 10.0% oxygeon were given, respectively.Rats were sacrificed at 1, 3 and 6 hours after injury for gross anatomic examination, light and electron microscopeobservation and lung water determination. The level of SP-A in BALF was detected by Western blot. The data wereprocessed by t test or Chi-square test. Results The respiration increased with shortness of breath and dysphoria inrats of BA Ⅰ and BA Ⅱ groups, and obvious cyanosis on the lips and nose in rats of BA Ⅱ group after blast injury.The lung water in rats of all injury groups was significantly higher than that in normal control group (P<0.05).Gross anatomy changes were mainly pulmonary bleeding and edema. Under light microscope, incrassation of alveo-lar wall, bleeding in alveolar and mesenchyme edema were found. Whereas under electron microscope, breakageof alveolar wall and decrease of lamellar bodies in type Ⅱ cell were observed. All these changes were most obviousin BA Ⅱ group followed by BA Ⅰ and BI groups in severity decling order, with mortality rate of 37.5%, 11.1%and 2.1% respectively at 6 hours (P<0.01). The SP-A level in BALF decreased significantly (P<0.01) andhad a good negative relationship with the lung water after injury (r=0.796, P<0.001 ). Conclusions Blastinjury combined with hypoxia significantly deteriorates the lung injury. More severe and longer hypoxia may resultin more severe lung injury and higher mortality rate. A decrease in SP-A value in BALF shows a good negative re-lationship with the pulmonary edema. The SP-A can be a good indicator for lung injury severity after blast injuryand blast injury combined with hypoxia.

Black spot disease is a significant worldwide disease on the rose plant. Due to this infection, the leaves become yellow and eventually fall off. The occurrence of this disease has become a major problem, especially in landscape purpose. Therefore, this research was conducted to isolate fungal species from black spot disease in rose and identify using morphological characteristics. Then, all the isolates were tested for pathogenicity to confirm Koch's postulates. In this study, four fungal isolates have been successfully isolated from black spot disease in rose namely Rhizoctonia sp. (one isolate), Colletotrichum sp. (two isolates) and Penicillium sp. (one isolate). Based on pathogenicity test result using potato dextrose agar (PDA) plug technique, fungus UMTT27R (Penicillium sp.) showed highly pathogenic on rose's leaves with disease severity (DS) = 88.89% followed by UMTT13R (Colletotrichum sp.) with DS=72.22%, UMTT21R (Colletotrichum sp.) with DS=66.67% and UMTT4R (Rhizoctonia sp.) with DS=61.11%. Correct identification of fungal pathogens is very important to strategize a proper method to control the black spot disease in rose cultivation.


Bias operating point has important influence on linearity of LNA.A fixed bias operating point is necessary for LNA to linearly amplify the signals.An improved dual active bias technology was presented,in which two parallel active bias circuits was used to supply DC bias for LNA to stabilize bias operating point of the amplifier.Based on JAZZ 0.35 μm SiGe process,an LNA was designed using the improved dual active bias technology.Simulation results showed that the LNA had a gain of 22.03 ± 0.46 dB,a noise figure(NF) below 3.7 dB,and an IIP3 of 5 dBm at 2.0 GHz over bandwidths ranging from 1.8 GHz to 2.2 GHz.Compared with a traditional passive biased LNA,IIP3 of the new circuit increased nearly 10 dBm,which demonstrated the effectiveness of the linearity enhancement of the improved dual active bias technology.


In this study we have investigated whether the defensin-like gene spi 1, isolated from Norway spruce, contributes to quanti- tative disease resistance and is a suitable candidate for utilisa- tion in Norway spruce breeding programmes. The following questions have been raised: (1) Can the putative defense gene, spi 1, improve the defense towards microbial pathogens in a model plant species, tobacco? (2) Is it possible to produce trans- genic plants of Norway spruce that overexpress spi 1 and are less susceptible to the pathogenic fungus Heterobasidion anno- sum? Compared to control plants, tobacco plants expressing spi 1 under an enhanced CaMV 35S promoter permitted less growth of the bacterial pathogen Erwinia carotovora. Embryo- genic cultures of Norway spruce were transformed with a simi- lar construct. The general phenotype of regenerated transgenic plants was normal, although it was difficult to maintain certain sublines in culture owing to poor initial growth. Among the transformed plants those with the highest content of SPI 1 displayed reduced fungal growth in the sapwood after inocula- tion with H. annosum. In conclusion, the spi 1 gene increases resistance in both homologous and heterologous systems.


Since .the second world war, radiation shielding research has made great progress mainly along with the computer progress. The research theme has extensively changed over these fifty years due to the increasing use of nuclear facilities such as fission reactors, accelerators, radioisotope and fusion research facilities. Recently, the space utilization is also one of the important field of shielding research. Very roughly speaking, radiation shielding research first started from radioisotope sources and extended to fission reactors, fusion devices/reactors, then accelerators, with the result that the energy region of interest has become higher and higher. This tendency is symbolized by the change of this conference title from reactor shielding to radiation shielding. In shielding research, non-charged particles such as photons and neutrons are the main radiation to be considered, but with increasing energy, high-energy charged particles that produce secondary photons and neutrons must also be considered. Electrons produce bremsstrahlung radiation through the electro-magnetic cascade process and neutrons through the photonuclear process, and light/heavy ions produce neutrons and photons through the intraand inter-nuclear cascade processes. Muons also become important in the very highenergy region due to their strong penetrating power. The shielding research can be overviewed herewith from the experimental and calculation studies.

Antioxidants are agents which scavenge free radicals and prevent cellular damage cause by them. They reduce the damage due to free radicals by neutralizing them before they can attack the cells. The aim of this research was to evaluate the antioxidant, nutritional and antinutritional properties of two leafy vegetables, Cleome rutidosperma and Cassia tora consumed in Adamawa State, Nigeria. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) models were used to determine antioxidant activities of extracts. Nutritional composition and antinutritional properties were determined using standard procedures. There was a significant (p=0.05) decrease in the concentration of DPPH radical due to the scavenging activity of ethanol leaf extract of Cleome rutidosperma compared to control/standard. In FRAP also, C. rutidosperma ethanolic extract exhibited higher ferric reducing power than C. tora. Proximate analysis revealed the nutrients for C. rutidosperma and C. tora as; crude protein (31.06±0.00% and 26.24±0.00%), fat Original Research Article Sha'a and Pwakangdi; AFSJ, 14(4): 18-27, 2020; Article no.AFSJ.55164 19 (7.13±0.00% and 6.93±0.10%), ash (15.17±0.61% and 11.60±0.00%), crude fiber (11.06±0.01 and 13.19±0.10%), moisture (9.99±0.00% and 9.12±0.10%), NFE (25.60±0.10% and 32.94±0.10%) respectively. Antinutritionals in ethanolic extracts of C. rutidosperma and C. tora were; oxalates, saponins, tannins, cyanogenic glycosides, phytate and alkaloids. Both vegetables revealed good percentages of proteins which can be used to compliment other sources of protein. All antinutrients of extracts were within tolerable levels.

RNase footprinting and nitrocellulose filter binding assays were previously used to map one major and two minor binding sites for the cell protein eEF1A on the 3 (cid:1) ( (cid:1) ) stem-loop (SL) RNA of West Nile virus (WNV) (3). Base substitutions in the major eEF1A binding site or adjacent areas of the 3 (cid:1) ( (cid:1) ) SL were engineered into a WNV infectious clone. Mutations that decreased, as well as ones that increased, eEF1A binding in in vitro assays had a negative effect on viral growth. None of these mutations affected the efficiency of translation of the viral polyprotein from the genomic RNA, but all of the mutations that decreased in vitro eEF1A binding to the 3 (cid:1) SL RNA also decreased viral minus-strand RNA synthesis in transfected cells. Also, a mutation that increased the efficiency of eEF1A binding to the 3 (cid:1) SL RNA increased minus-strand RNA synthesis in transfected cells, which resulted in decreased synthesis of genomic RNA. These results strongly suggest that the interaction between eEF1A and the WNV 3 (cid:1) SL facilitates viral minus-strand synthesis. eEF1A colocalized with viral replication complexes (RC) in infected cells and antibody to eEF1A coimmunoprecipitated viral RC proteins, suggesting that eEF1A facilitates an interaction between the 3 (cid:1) end of the genome and the RC. eEF1A bound with similar efficiencies to the 3 (cid:1) -terminal SL RNAs of four divergent flaviviruses, including a tick-borne flavivirus, and colocalized with dengue virus RC in infected cells. These results suggest that eEF1A plays a similar role in RNA replication for all flaviviruses. reduced virus yield. Together, these results provide strong support for a direct role for eEF1A in the synthesis of WNV minus-strand RNA.


integrity of women religious." He sees their role to be "one of increasing significance in the lives of all of us, whether Catholic or not, whatever may be the temporary setbacks they endure in the present dispensation [of Roman reaction]." Other essays include Gregory Baum's "Looking South from Canada," John Deedy, writing on the urgencies of relating more creatively to young people and women, and the always-worth-reading Sidney Callahan on "The Laity and Alienated Catholics." Donald Senior and Carroll Stuhlmueller collaborate for an important essay that traces the history of the biblical movement in the United States especially under the aegis of the Catholic Biblical Association of America, and they then assess the implementation of Vatican II in the area of biblical studies. Monika Hellwig, in "American Catholic Theology Now," writes of the shift that has accompanied the maturing of Catholic theology in the U.S. "I believe most of us are still rather astonished when we find issues of Concilium edited by some of our own, and relaying American thought to Europe and elsewhere. And it is with similar surprise," she comments, "that we begin to realize that some of the best contemporary scholarship and some of the most creative synthetic thought is coming out of our own great universities on this side of the Atlantic." John Eagleson writes on liberation theology, Robert Imbelli on priestly identity, Marie Augusta Neal on American sisters, Kathleen Hughes on liturgical life, Basil Pennington on Thomas Merton as a spiritual guide for the '80s. The volume concludes with an essay on Catholic higher education by Theodore Hesburgh, and an essay on peace by Daniel Berrigan. Michael Glazier has done a commendable job in bringing this book together. In addition, his introductory essay on Philip Scharper is written with a warmth and grace and class that suits its subject and reveals an author who is clearly a kindred spirit, as his own distinction as a publisher shows. Karl Rahner, speaking shortly before his death in 1984, saw Catholicism heading into "a wintry climate, on a journey that is gloomy, depressing and aimed at restoration." It is a continuing aggiornamento that is the aim of the contributors to this book, a book that provides warmth and wisdom even in "a wintry climate." Written in a style that is accessible to all, this volume belongs in both the classroom and the library. It is a fitting tribute to Philip Scharper.


Recently currency instability and its economic and social consequences prompt the question whether and to what extent a common currency could have served to prevent or meliorate the Asian crisis. This paper examines the advantages and costs of such a proposal, using the experience and institutions of European monetary union as a starting point. It concludes that while the technical economic obstacles are not insurmountable, the political and social factors presupposed in a union are more important in explaining the region?s lukewarm reception of the proposal.

The aim of this literature review paper is to show the negative consequences of globalization via the mass media, especially the internet, on student sexual abuse, to provide analyses of children's rights and their shortcomings in this arena in urban areas, and to offer some solutions to reducing student vulnerability. The limitations of the research are based on insufficient information in the case of sexual abuse due to cultural issues in different states, which mean that not all cases of abuse by parents, teachers and the authorities are reported, so it is impossible to adduce complete data on victims of student sexual abuse. We shall attempt to show the growing danger of sexual abuse for students that poses a threat to future generations due to one of the major aspects of globalization—the internet—by taking into account diverse cultural communities and their dynamic limitations and political and social structures. This paper studies the different laws on child sexual abuse in some countries and some of the national and international organizations that support children's rights. It shall also define the increasing sexual abuse of students and their access to the internet. RESUMEN


Accountability Historical Perspective Accountability is increasingly putting pressure on all educators to prove effectiveness for themselves and for the program of which they are a part (Studer, 2004). Traditional counselors were evaluated based on such things as the number of students seen, quantity of programs conducted, and/or timeliness of reports, with the value of these activities based on counselors "intuition" testimonial, or personal impressions (Myrick, 1993). Historically, professional school counselors have not been held to the same accountability as other educators and have rarely been included in the conversations about how their contributions positively affect every student's academic life (Stone & Dahir, 2004). In the future, profession-

To the extent that firm decisions are made under uncertainty, all firms need to deal with risk. The concept of risk is relatively unexplored in transitional economies. This study attempts to examine risk issues in Chinese private firms during different phases of economic transition. I distinguish between organizational and project level risks and argue that China's economic transition affects the two levels of risk in different ways. I investigate private firms' risk behavior based on the specific risk they face. My central argument is that firm risk needs to be examined beyond a unidimensional perspective and firms' risk behavior may vary, depending on the risk they deal with. This study takes a step toward understanding the relationship between private property and risk taking in China's transitional economy, a question raised by Phan, Zhou, and Abrahamson (2010) recently.


Profit shifting due to manipulation of transfer prices erodes the corporate tax base in high tax countries. To protect tax revenues, governments typically apply the arm's length principle to 'correctly' assess the value of intracompany trade and royalty income based on observed market transactions such as in comparable outsourcing relationships. We develo pam odel of heterogeneousfirms which are subject to agency costs in external financing and choose between outsourcing and foreign direct investment. We show that the application of the arm's length principle distorts financing and investment of multinational firms, the choice between outsourcing and direct investment, and leads to a reduction of world welfare.

MXenes have recently gained significant research interest due to its graphene-like structure that allows for a multitude of applications such as electronics, batteries and optics to be realized. In this work, stable Q-switched pulses are passively obtained from a thulium-doped fiber laser using an MXene Ti3C2TX coated microfiber as a saturable absorber (SA). The generated pulses have center lasing wavelength 1976 nm with a pulse repetition rate and pulse width ranging between 16 kHz to 59 kHz and 13 µs to 2.4 µs respectively. The generated pulses can be tuned over a wavelength range of 155 nm from 1895 nm to 2050 nm. The MXene based SA has signficant potential for generating pulsed laser outputs that will find uses in the areas of sensing, medicine and spectroscopy around the 'eye safe' 2 µm region.


Objective:To evaluate the applicable value of weighted TOPSIS method in comprehensive assessment of medical quality in hospital. Methods: Evaluation indicators were selected and weighted, and data matrix and normal matrix were established on the basis of hospital statistic data from 2002 to 2006. Weighted Euclid distance and relative closeness between evaluation indicators of each year and optimal vector, worst vector were calculated. Results: The optimal vector Z+ was (0.4479, 0.4485, 0.4486, 0.4515, 0.4474, 0.4528, 0.4737, 0.4714, 0.4970), the worst vector Z-was (0.4466, 0.4452, 0.4458, 0.4420, 0.4467, 0.4397, 0.3778, 0.4254, 0.3568). The medical quality of the hospital was improving year by year, with best results in year 2006 and worst results in year 2002. Conclusions: The weighted TOPSIS method is applicable in the assessment of Medical quality in hospital.


Patients with a physical illness are three to four times more likely to develop a mental illness than a member of the average population. Patients admitted to an acute setting have a 28 per cent chance of also having a diagnosable psychiatric disorder. A further 41 per cent have sub-clinical symptoms of anxiety or depression. The rates of psychiatric illness for older adults in general hospital beds are as follows: up to 40 per cent have dementia, 53 per cent have depression and 60 per cent have delirium. During an economic downturn these figures are likely to increase. Most of these mental illnesses are treated very quickly and effectively if the symptoms are identified early. However, the current composition of some acute and mental health services means that the physical and mental conditions of patients are treated separately. This means that many general hospital inpatients with co-morbid physical and mental illness have little access to appropriate mental health services, either while in hospital or following discharge.


Polymerase chain reaction (PCR), a central technology for molecular diagnostics, is highly sensitive but susceptible to the risk of false positives caused by aerosol contamination, especially when an end‐point detection mode is applied. Here, we proposed a solution by designing a clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 eraser strategy for eliminating potential contamination amplification. The CRISPR/Cas9 engineered eraser is firstly adopted into artpcr reverse‐transcription PCR (RT‐PCR) system to achieve contamination‐free RNA detection. Subsequently, we extended this CRISPR/Cas9 eraser to the PCR system. We engineered conventional PCR primers to enable the amplified products to contain an implanted NGG (protospacer adjacent motif, PAM) site, which is used as a code for specific CRISPR/Cas9 recognition. Pre‐incubation of Cas9/sgRNA with PCR mix leads to a selective cleavage of contamination amplicons, thus only the template DNA is amplified. The developed CRISPR/Cas9 eraser, adopted by both RT‐PCR and PCR systems, showed high‐fidelity detection of SARS‐CoV‐2 and African swine fever virus with a convenient strip test.
