Aging is a natural process that affects all subjects. Thus, it is described as a dynamic phenomenon, continuous and not reversible, associated with biological, psychological and social aspects. This article aimed to investigate the relationship between self - efficacy and physical activity in elderly cognition. A systematic review of the literature was performed according to the PRISMA method. For this, the data collection was done by means of a survey of scientific productions, in Portuguese language, available in the SciELO database, adopting the following descriptors in different combinations: elderly, self-efficacy, physical activity and cognition. For the analysis of the data, 43 abstracts of the articles of the systematic review were used, which were read carefully, and their abstracts were separated and organized in a single corpus and were analyzed using the software IRaMuTeQ. Therefore, it was possible to verify that there is a significant relationship between self-efficacy and physical activity in the cognitive performance of the elderly, which can affect considerably the plasticity of the nervous system, the monitoring capacity, the modulation of cognition, emotion and behavior.


Novel binuclear Co(II) complexes with N-functionalized cyclam, N,N',N",N''' -te- trakis(2-pyridylmethyl)tetraazacyclotetradecane (tpmc) and one of the aromatic mono- or dicarboxylato ligands (benzoate, phthalate or isophthalate ions) were prepared. They were analyzed and studied by elemental analyses (C, H, N), electrical conductivities, VIS and IR spectroscopy and magnetic as well as cyclic voltammetric measurements. In Co2(C6H5COO)2tpmc(ClO4)2 . 3H2O, the benzoate ligands are most probably coordi- nated as chelates in the trans-position to each Co(II) and the macrocycle adopts a chair conformation. In the complexes Co2(Y)tpmc(ClO4)2 . zH2O, (Y = phthalate or i-phtha- late dianizon, z = 2; 4), it is proposed that the isomeric dicarboxylates are bonded com- bined as bridges and chelates. The composition and the assumed geometries of the com- plexes are compared with the, earlier reported, corresponding Cu(II) complexes. Cyclic voltammetry measurements showed that the compounds are electrochemically stable.

With the fast development of Monte Carlo global illumination, many new ideas are put forward and needed to be tested whether it is effective. A general and efficient testbed that can provide all kinds of Monte Carlo global illumination algorithms is in great demand. In this paper, we propose a Monte Carlo global illumination testbed for virtual environment -- RenderStorm, which is of highly modular architecture, good expansibility and suitability to synthesize still and animated images. The engine of this testbed is Monte Carlo path tracing technique. Based on Monte Carlo path tracing, it can be easily used for realizing a lot of Monte Carlo global illumination algorithms. A perfectly designed class is the distinct feature of the system. We provide the system with a lot of libraries, which can be used easily.


In a glucose‐salt solution (EBSS), asparagine (ASN) stimulates ornithine decarboxylase (ODC) activity in a dose‐dependent manner. We determined the mechanism by which ASN induces ODC activity. In the absence of amino acids (AA), an antizyme 20‐kDa isoform (AZ‐1‐20), which inhibits ODC activity, increased in a time‐dependent fashion. ASN prevented the accumulation of AZ‐1‐20 and rapidly induced ODC activity, as did glutamine and α‐amino iso butyric acid. In contrast, lysine and valine induced AZ‐1‐20 expression and decreased ASN‐induced ODC activity. ODC induction by ASN was lower in DMEM containing AA as compared to that in DMEM without AA, suggesting that AZ‐1‐20‐inducing AA may partially neutralize the effect of ASN. Incubation in EBSS for 6 hrs increased AZ‐1‐20 protein levels, and addition of ASN decreased accumulated AZ‐1‐20. Cycloheximide similarly caused elimination of accumulated AZ‐1‐20 but did not alter the rate of decrease due to ASN. Actinomycin‐D failed to prevent AZ‐1‐20 expression in EBSS. These results suggest that ASN modulates AZ‐1‐20 levels by regulating synthesis. ASN prevented the phosphorylation and caused accumulation of eukaryotic initiation factor binding protein (4EBP1). Thus, by preventing the phosphorylation of 4EBP1, ASN causes it to accumulate and bind to eIF4E resulting in the inhibition of the synthesis of AZ‐1‐20, allowing the activation of ODC.


The utility model discloses a light-emitting diode (LED) side lighting panel lamp which comprises a main frame, a rear cover, a light guide plate, a diffusion plate and a lamp plate. One side of the main frame in a square frame shape is sealed through a rear cover, the other side of the main frame is sealed by the diffusion plate, the light guide plate clings to the inner side of the diffusion plate, the lamp plate is arranged on one side of the light guide plate, and a plurality of LED lamps right face to the lateral side of the light guide plate, a water-proof rubber strip sealing a joint is arranged on the joint between the main frame and the rear cover, and water-proof double-face adhesive is arranged between the diffusion plate and the main frame. According to the LED side lighting panel lamp adopting the technical scheme, due to the fact that the water-proof rubber strip and the water-proof double-face adhesive are arranged, a sealed space is formed in the LED side lighting panel lamp, water drops, dust and the like are difficult to enter the LED side lighting panel lamp, and thus protection grade of the LED side lighting panel lamp is greatly improved. The LED side lighting panel lamp not only can be used in a damp environment, but also can be used outdoors even it rains.


Despite reform efforts to involve parents, parent–school relationships in urban districts are rare. This qualitative study used a constructivist grounded theory approach to gain an understanding of how parent social networks, specifically relationships with other parents in the school, influence parent perceptions of their role in the educational process and their efficacy to fulfill perceived roles. Findings suggest that parents have differing perceptions about their role and differences in efficacy for involvement; however, relationships with other parents are important resources for role construction and efficacy, and may serve to lessen the disconnect between parents and schools in high-poverty districts.


This study was carried out to investigate the difference of growth characteristics, yield and extract content between upland and paddy ginseng cultured with 4year-old ginseng in 2003. Although upland ginseng showed larger variation in yield than that of paddy ginseng, the average of it was greater than that of paddy ginseng because it showed better growth of aerial part and higher survival rate than that of paddy ginseng. Moisture content of fresh root was 71.8% (68.5 ~ 73.1 %), and 72.7% (70.2 ~ 74.9%) on average in upland and paddy ginseng, respectively. Paddy ginseng showed higher hardness in taproot, and higher rate of rusty colored root than that of upland ginseng. The ratio of taproot dry weight in upland ginseng was smaller than that of paddy ginseng, while that of lateral root was larger in upland ginseng. Ratio of marketable root (>60 g) to total harvested roots was 13.7 % (0.82 ~ 8.0%) and 7.7 % (1.6 ~ 12.6%) in upland and paddy ginseng, respectively. Extract content did not show distinct difference between upland and paddy ginseng, but it showed large variation from 16.1 to 25.1% in taproot, and from 24.2 to 32.5% in lateral root depanding on the ginseng field examined.

Lipophilic flavonoid aglycones can accumulate on plant surfaces [1]. External deposits of aglycones are related to their diverse functions, for example as antioxidants [2], for screening of UV-B radiation [3,4], as antifungal compounds [5] and as signalling agents both above and below ground between plants and other organisms [6]. It is necessary to find a rapid and sensitive method for study of the distribution and dynamics of surface flavonoids and the effect of different factors on their synthesis in plants. TLC–densitometry enables determination of flavonoids by exploiting their fluorescence under UV irradiation. TLC–densitometry is the method of choice for screening because it is simpler, more rapid, and less expensive than HPLC and has satisfactory sensitivity and reliability [7,8].


The authors present an effective-medium theory of the optical diamagnetic response of very dilute metal colloids. These dispersions of ferromagnetic metal clusters in diamagnetic hosts show a large, linear response under an applied magnetic field, which is of interest for emerging applications in sensing, integrated optical communications, and magneto-optical current transformers and transducers. This theory could be further extended to describe e.g., metal inclusions in polymers or glasses.


One of the most important features of the criminal procedural legislation of the Republic of Serbia is the institute of conditional deferral of criminal prosecution as a key aspect of the principle of opportunity, which was standardized in order to create a normative basis for increasing the efficiency of criminal proceedings. The subject of the paper is an analysis of the extent of the application of the institute, both in general and in terms of the structure of some of the obligations imposed on the suspect by the public prosecutor during the deferral of criminal prosecution in the Republic of Serbia from 2019 to in 2021. The aim of the paper is to point out the exceptional importance of the institute and to point out the fact of the necessity of both the adequate normative elaboration of the institute and its adequate application.


Record companies invest billions of dollars in new talent around the globe each year. Gaining insight into what actually makes a hit song would provide tremendous benefits for the music industry. In this research, we tackle this question by focusing on predicting rank of hit songs in the next 6 months. Our dataset is used in ZALO AI CHALLENGE 2019 in Hit Song Prediction problem including not only songs but also its information such as composer, artist name, released date, etc. Because of that, while most previous work formulates hit song prediction as a regression or classification problem, we present in this paper how to apply Gradient Boosting technique to treat it as a ranking problem. The resulting best model has a good performance when predicting whether a song is a top 10 dance hit versus a lower listed position with 1.48815 Root Mean Square Error - our result dominates most of the solution in this competition (better than 3rd ranked solution of 87 in total). Moreover, it is possible to further improve by extracting chords, tones and more information from each song to obtain the highlights of songs and by using linguistics model to offer high-level features of metadata.


This programme allows users who are experiencing troubles as a result of a civic issue such as a rubbish dump, sewage leak, or potholes, to file a complaint using photographs (Camera Module). The public can be notified of the resolved issue (through an image or message) by the relevant government agency. This software provides a transparent platform for customers to register complaints, view previous complaints, and validate that the problem has been resolved. So, the proposed system would be that people could take pictures of neighbourhood issues and submit them to a local government body, where the complaint would be lodged along with the issue's address, and the local government would then forward the problem to the appropriate department, which would handle the issue. Citizens will be informed of the current status of the complaint, as well as what actions are being done to address it and how quickly the problem can be resolved.


Abstract The culture of a school is a critical component of school improvement efforts. However, changing the culture of a school is no easy feat. In this qualitative, single case study, we describe the perceptions held and strategies employed by one female principal newly assigned to a middle school in an urban setting. We examined the principal's perceptions about the challenges that she faced and the strategies she used, during a three-year timeframe, to turn around a middle school designated as chronically underperforming. Ultimately, the principal was able to move the school from a culture characterized as having poor academic performance to a place of engaged students. We identified the themes of demanding effective teaching, creating support systems, and shifting student discipline. We discuss these findings and their implications for research and practice.


In order to improve the accuracy of textile image segmentation, this paper presents a method of applying the MRF algorithm to the fabric image segmentation. Segmentation results could be obtained by three steps: First step is pretreating the original images. Second step is establishing the MRF model by way of the ICM algorithm. The last step is combining the bayesian theory and MAP. Several printing images are applied and perfect results are received in this experiment.


Editor: The Winter 1988 issue of AI Magazine carried a report I coauthored reporting on the June, 1987 Workshop on Theoretical Issues in Conceptual Information Processing. Despite the many chances I had to fix the manuscript, I somehow managed to miss an error that crept in and changed the intended meaning rather drastically in the section "From the Workshop Chair," by B. Chandrasekaran. A sentence in that section as published reads: "The goal of these gatherings has been to understand intelligence and cognition as feasible computations as they apply to the construction of performance programs for narrowly defined tasks (expert systems)." The sentence as originally written by Chandrasekaran read: "The goal of these investigations has been understanding intelligence and cognition as feasible computations, as opposed to the construction of performance programs for narrowly defined tasks (expert systems) or formalization per se " As readers can see, quite a difference in meaning His goal was to characterize how the shared goals of the participants in the TICIP series differ from some other groups of researchers in AI. All I can say is mea culpa, and I hope this letter may help to square things Sincerely,


A simple, economical, rapid, reliable and precise reverse phase high performance liquid chromatographic method has been developed for the simultaneous estimation of paracetamol, guaifenesin and dextromethorphan in syrup dosage form. The separation was achieved on a Phenomenex C 18 ( 250 × 4.6 mm ) 5μ column in isocratic mode with water: methanol: glacial acetic acid (60:38.5:1.5 v/v) as mobile phase at a flow rate of 1.5ml/min.The detection was carried out at 276nm.The retention time of paracetamol, guaifenesin and dextromethorphan were found to be 3.20, 5.80 and 9.45 min, respectively. This developed method was validated in terms of accuracy, precision, linearity, limit of detection, limit of quantitation and solution stability. The proposed method can be used for the estimation of these drugs in combined dosage forms in routine analysis.


The impact of human disturbances on forest stands was investigated in two tropical dry evergreen forests, which are also sacred groves or temple forests at Arasadikuppam (site AK) and Oorani (OR) on the Coromandel (east) coast of India. The two sites differ in their degree of disturbance. Site disturbances were classified into site encroachment, temple visitors' impact, degree of cattle and goat browsing, and resource removal. The total score of disturbance level at AK was more than twice (16) that (7) of the less disturbed site OR. A one-hectare permanent study plot was established at each of these sites. The highly disturbed site AK is characterized by short-statured forest (stand height ~ 5 m) with two strata, whereas the less disturbed site OR is comparatively tall-statured (~ 8 m tall) with three strata. The tree density (stems ≥10 cm girth at breast height - gbh) at site AK was twice that at OR (2815 and 1286 stems ha-1 respectively). Site AK was composed of 75% more multi-stemmed individuals than OR, but the less disturbed site OR was 55% more voluminous (basal area 27.3 m2 ha-1) than the highly disturbed site AK (17.6 m2 ha-1). Site OR comprised 77% evergreen species as against 65% at AK. Site AK contained a greater density (85%) of stems in the lowest girth class of 10-30 cm gbh, indicating a greater state of recovery from past disturbance than the less disturbed site OR (64%), which represents a mature forest stand or climax forest. The forest stand structure exhibited a reversed 'J' curve at AK, which was steeper for both girth frequency as well as basal area, while at OR the girth frequency curve was shallow but the basal area distribution was bell-shaped. The species-abundance-based similarity score between the highly disturbed site AK and the less disturbed site OR was 0.45. Tree diversity data of the two study sites are compared with three other comparable tropical dry evergreen forest sites (Kuzhanthaikuppam-KK, Thirumanikkuzhi-TM and Puthupet-PP) located within ~50 km radius on the Coromandel coast of India. Based on the degree of disturbance, the five sites can be represented as OR<TM<AK<KK<PP. There was not much difference in the forest composition (number of species, genera and families) of the two present study sites, but, when all the five sites are considered, species diversity was 20% less in the highly disturbed site PP. Evidently, human disturbances have an impact on forest stand characteristics such as stand height, number of strata, tree density, and basal area. Accepted 25 January 2003.


A type of electric energy management system based on infrared rays communication technique in residential parts of a city was introduced in this paper. Hardware design method of single-phase electronic watt-hour meter with infrared interface and choice of main components were presented.


The paper presents a novel algorithm for detection and measurement of indentations in Vickers hardness testing images, within a specific case of applied research on material quality evaluation based on image processing. The algorithm performs image segmentation by binarization, morphological filtering, and region growing, where the binarization threshold is automatically obtained from the input image. After identification of the rhombus shaped indentation footprint, its four vertices are determined using corner detection, which are used to calculate the diagonal lengths and the Vickers hardness number. The proposed procedure has been tested on 185 images of real data obtained by the micro hardness machine Mitutoyo HM-124, mostly from Steel-316 specimens, but also from Hafnium Nitride. Test images include specular-polished and rough surfaces, specimen with artifacts or imperfections, indentations with deformed or damaged edges, and low contrast images. Ground true diagonal lengths obtained in the conventional manual manner by an expert were compared with the results determined by our method. The proposed method achieves competitive accuracy compared to the best known methods, but it is simpler and hence more efficient.


In order to communicate to senior high school students some modern physics concepts, a course parallel to the traditional one has been proposed. This course describes historically some attempts to look for objects and phenomena that have not been observed up to now, although they have been predicted by well established physical theories. Among the great illusions of modern physics we have considered the magnetic monopole, the quarks, and the gravitational waves. The ideas related to the magnetic monopole are presented in detail in this article as an example. Some specific comments on the course imparted in 1986–87 with these ideas are also made.


The mode conversion from the TE 01 wave to the TM 11 wave which normally occurs in a curved round waveguide may be reduced by applying a uniform dielectric coat a few mils thick to the inner wall of the waveguide. Such a dielectric coat changes the phase constant of the TM 11 wave without affecting appreciably the phase and attenuation constants of the TE 01 wave. Thus, relatively sharp bends can be negotiated to change the direction of the line or deviations from straightness can be tolerated. For each of these two cases a different optimum thickness of the dielectric coat keeps the TE 01 loss at a minimum. At 5.4-mm wavelength a bending radius of 8 ft in a ⅞-inch pipe or 50 ft in a 2-inch pipe can be introduced with 0.2 db mode conversion loss. Deviations from straightness corresponding to an average bending radius of 300 ft can be tolerated in a 2-inch pipe at 5.4-mm wavelength with an increase in TE 01 attenuation of 5 per cent. Serpentine bends caused by equally spaced supports of the pipe may, however, increase the mode conversion and cause appreciable loss at certain discrete frequencies. Compared with the plain waveguide the dielectric-coated guide behaves more critically in such serpentine bends. The mode conversion from TE 01 to the TE 02 , TE 03 , … waves at transitions from a plain waveguide to the dielectric-coated guide is usually very small.


The main objectives of the current research were to identify the changes that took place in the rural households' human social capitals as a result of the activities of "West Noubaria Rural Development" project funded by IFAD. Also, to identify the rate of changes. The study was conducted on a sample of 165 respondents from 4 villages (Tiba and Al-Entlaqa in the west of AlNoubaria) at El-Beheira Governorate who were selected using simple random sampling. Data were collected during the period from February to April 2017, using a questionnaire administrated through personal interviews. The study revealed the following results: 1. There is a significant difference (at 0.05) between human capital before and after the project implementation in favor of post project impact with a relative change in human capital of about 34.68%. 2. There is a significant difference (at 0.05) between social capital before and after the implementation of the project in favor of post project impact with a relative change of about 26.22%.


For long term space missions, higher plants are necessary to be included in life support systems. The Micro Ecological Life Support System Alternative (MELiSSA) project of European Space Agency (ESA) is based on a closed life support system where microbial and higher plant compartments support the consumer's compartment. Plants consume the possible recycling wastes (waste water and CO2) and provide fresh food, potable water and oxygen to the crew. One of the key points for this kind of study is to maintain a system which recycles all the elements C, H, O, N, S, P, etc. That is why, the study is based on the modelling of conversion stoichiometries ; they are the results of the control parameters of the system (physical limitations of mass and energy exchanges). As a preliminary step, we have established leaf metabolic model (a sub model of the plant biochemical model) involving central carbon metabolism using metabolic techniques, elementary flux mode analysis (EFMA) and metabolic flux analysis (MFA). It is associated to an integrated approach of energetics and central metabolism. Due to data limitations, the leaf metabolic model was constructed taking the biomass composition of lettuce (Lactuca sativa) from United States Department of Agriculture (USDA) and validated with the experimental data where lettuce grown in controlled Environment Systems Research Facility (CESRF) of University of Guelph (Canada). For the first approach, the model is satisfying and promising ; it can predict the biomass production connecting the physical plant growth factors (light, CO2 and water availability, etc.) along with time course growth and biomass composition. However, our results show the lack of sufficient data ; hence, various kinds of measurements required for more accurate model predictions are proposed. The future model must be able to control and manage the plant growth for human survival knowing the fluxes from other compartments of MELiSSA loop. Further, the approach described here can be used more generically in all kinds of metabolic studies and modeling, especially for studying simultaneous and/or consecutive photosynthetic and respiratory metabolisms.


The great success in scientific applications and transaction processing has been achieved by computer architecture based on RISC and hierarchical memory. New application requirements and technological limitations, however, disqualify the existent architecture and make it the one for new application domains featuring multimedia processing and personal mobile computing. The disqualifications are analyzed and a new architecture, Vector IRAM, is introduced.


While childhood vaccination programs, such as WHO's Expanded Program on Immunization, have had a dramatic impact on child morbidity and mortality worldwide, lack of coverage with several existing vaccines is responsible for large numbers of child deaths each year, mostly in developing countries. According to WHO estimates, increased coverage of three vaccines alone – pneumococcal conjugate vaccine (PCV), rotavirus vaccine (Rota), and Haemophilus influenzae type b (Hib) vaccine – could have prevented one and a half million deaths in children under five years in 2002. In deciding whether to implement interventions to expand vaccination coverage policy makers often consider economic evaluations. Past evaluations, however, have usually ignored both important vaccination benefits and potentially large cost reductions in vaccination delivery. We demonstrate for the example of benefit-cost analysis (BCA) of the Hib vaccination that past studies have mostly taken narrow evaluation perspectives, focusing on health gains, health care cost savings, and reductions in the time costs that parents incur when taking care of sick children, while ignoring other benefits, in particular, outcome-related productivity gains (Hib vaccination can prevent permanent mental and physical disabilities) behavior-related productivity gains (reductions in child mortality due to Hib can trigger changes in fertility which in turn may stimulate economic growth) and community externalities (Hib vaccination can prevent the development of antibiotic resistance and reduce the risk of Hib infections in unvaccinated persons). We further show that the costs of Hib vaccine delivery can be reduced if the monovalent Hib vaccine is replaced by combination vaccines. Such cost reductions have usually been ignored in CBA of Hib. Our analysis thus suggests that past BCAs are likely to have substantially underestimated the value of Hib vaccination, even though most have found it to be cost-beneficial. Unless future BCAs of childhood vaccinations take full account of benefits and costs, policy makers may lack sufficient information to make the right decisions on vaccination interventions.


The problem on maximum likelihood estimation of ratios between means and standard diviations under semi-order restriction was put into consideration for k(k3)normal populations with unknown means μ1 and variances σ2i.0,i=1,2,…k.A procedure of obtaining the maximum likelihood estimators ofμi's andσi's under the semi-order restrictions was proposed.For k=5 case,some connected results and simulation results were proposed.


Approximate number is a kind of numeral expressing the indefiniteness of number,which is usually composed of numeral connection and numeral with indefinite words. Approximate number in "SouShen Ji" accepted and developed that of ancient Chinese,but lacked some new forms of modern Chinese and reflected obviously the characteristics of medieval Chinese.


ABSTRACT Recent literature shows that in the US gasoline prices are higher in locations using more odd prices (particularly those ending in five and nine digits), since they coarse the pricing grid and act as a focal collusive point. We replicate this analysis for the Italian market, obtaining the opposite result. Since the rightmost digit of the retail gasoline prices in Italy is the third and not the second decimal place, coarsening the pricing grid is not sufficient to support a collusive behaviour.


Based on the annual projects supported by National Social Science Foundation,this paper analyses the distribution of the Social Science with the information and literature from 1993 to 2007.It has been found that the projects supported by National Social Science Foundation have increased year by year.Beijing,Shanghai,Hubei,Jiangsu and Guangdong were the maximal victor.On the contrary,Shanxi,Ningxia,Qinghai,Tibet and Hainan were the 5 minimal provinces.There are lots of researchers of social science in Chinese Academy of Social Sciences,Renmin University of China,Peking University,Nankai University,Wuhan University and Fudan University,so we can find that the academic centers centering on these universities have taken form gradually.The analyses show that there have been both objective factors such as the historical difference between various disciplines and units as well as some subjective factors as the design of the scientific research foundations and the undertaking of them.


Sliding friction heat is recognized as an important factor for the physical properties and stress levels of materials,and the numerical simulation method of sliding friction has some advantages in the current physical test,such as convenience and test cost.On the basis of the friction interface atomic vibration theory,the user subroutine VFRIC provided by ABAQUS is used to develop a friction model,and the model takes several factors(contact pressure and relative sliding speed) into consideration in the numerical simulation.Finally,an example of metal friction under wearless dry friction is introduced to verify the effectiveness of the given friction model.


Using a non-equilibrated solid-phase microextraction/gas chromatography/mass spectrometry technique, differentiation between a wide variety of types and examples of artificial flavors has been demonstrated. Addition of an internal standard to the samples, as received, allowed for the calculation of yields on a µg g−1 basis for the majority of headspace volatiles. The relative standard deviation values expressed as percentages were between 3 and 5%. The precise nature of the approach coupled with the compound identification capacity of the mass spectrometer afforded the capability to easily differentiate between multiple sources of artificial flavors. With a total analysis time of approximately 30 min and the absence of solvent, this approach has the capability of detecting and quantifying the presence of the low-molecular-weight solvents often used in the preparation of artificial flavors. Such a capability represents a distinct advantage over more conventional methods of solvent dilution. Results from conventional gas chromatography/mass selective detector analyses are contrasted and compared with the results obtained from the headspace SPME approach.

The California Energy Efficiency Strategic Plan set aggressive targets for energy reduction in various sectors and end-uses, including lighting. The plan also calls for more substantial efforts toward market transformation. In support of the plan's lighting goals, the California investor-owned utilities (IOUs) created a statewide Lighting Market Transformation (LMT) program to develop market transformation strategies for targeted lighting technologies. To inform this market transformation strategy development, the LMT program worked with The Cadmus Group, Inc., to develop an Excel-based planning support tool called the Lighting Solutions Workbook that helps prioritize opportunities for the IOUs to achieve the highest energy savings. The most innovative aspect of the Lighting Solutions Workbook is it makes a wealth of knowledge about market barriers, savings potential, and technology saturation available to planners and decision makers within a logically structured framework that spans major market sectors, applications, and technologies. Cadmus compiled the data populating this tool from multiple sources; the LMT program will update it regularly as new information becomes available. The Lighting Solutions Workbook is the product of a collaborative effort involving lighting experts from utilities throughout North America, Pacific Northwest National Laboratory, California Lighting Technology Center, and other organizations. This paper describes the need for a framework to organize lighting market information, the development of that framework, and the population of the tool with available data. This tool represents a transparent and datadriven approach to planning that can be applied to other regions and end-uses.


Since 1065, when the first university in Europe was founded – University from Parma, higher education has been in a continuous reformation, both from educational politics point of view and from funding mechanisms point of view. Therefore, this study aims at presenting the main funding models for European higher education, in order to a future design of a funding model able to maximize the efficiency for using and/or distributing public funds for tertiary education.


Objective To observe the changes of T cell subsets and immunoglobulin in blood of different subtypes of Henoch-Schonlein purpura(HSP)in the acute phase,and to explore their roles in the pathogenesis of HSP. Methods One hundred and fourteen children diagnosed as HSP according to classification criteria of American Rheumatism Association were chosen as subjects,untreated with steroids and immune depressants in 2 weeks.They were divided into 5 groups according to clinical manifestations:skin group(n=29),joint group(n=26),abdomen group(n=19),kidney group(n=13),mixed group(n=27).Twenty nine normal children were chosen as controls.The levels of CD3, CD4 and CD8 were detected by flow cytometry.IgA,IgG,IgM,C3 and C4 were detected by specific protein analytical system. Results Compared with controls,the level of CD4 and the ratio of CD4/CD8 in children with HSP significantly decreased(P0.05),while the level of CD8 increased(P0.05).Except that in skin group,the levels of B cells in the other 4 groups were significantly higher than in control group(P0.05).NK cells were significantly lower in abdomen group and kidney group than in control group(P0.05).IgA were significantly higher in mixed group than in control group(P0.05).However,IgM in joint group and mixed group were significantly lower than in control group(P0.05). Conclusion There is disorders of T cell subsets and parasecretion of immunoglobulin in acute HSP.The levels of blood IgA in HSP might be related to multiple factors.


The paper presents an image registration method based on a two-dimensional Hopfield neural network, where the problem of image matching is treated with the minimization of the energy function of the Hopfield neural network. The input data used for registration are the locations of the corner points extracted from the images. In order to improve and expedite the matching process, a fast block-based algorithm is put forward, together with the laboratory results obtained, which show the effectiveness of the algorithm.


The public opinion of the Latino community is an understudied area within the political science literature. This analysis contributes to this literature by investigating the role of group consciousness across both Latino salient and general policy areas utilizing the 1999 Washington Post/Henry J. Kaiser Family Foundation National Survey of Latinos. By including both issue areas that are salient to the Latino community (immigration, bilingual education) as well as those that are not directly tied to Latinos (abortion, death penalty), I test the primary hypothesis that group consciousness has a greater impact on Latino political attitudes across issues that are directly tied to ethnicity than on those that are not. Results from this analysis support the overall theory, as perceived discrimination motivates public opinion toward both immigration and bilingual education, and collective action toward immigration. Among other factors, nativity and the length of time lived in the U.S. have the greatest influence on Latino public opinion. about the political opinions of the Latino community in the U.S. This is a result of a general disinterest in the attitudes and opinions of Latinos prior to the late 1980s (de la Garza 1987). The more recent interest in the political attitudes and beliefs of Latinos has been driven by the rapid growth of this population, which has generated interest within both the political and marketing industries. This analysis is an effort to contribute to the growing knowledge of Latino public opinion by investigating the relationship between group consciousness and the public opinion of Latinos across both general and Latino salient issue areas. By including both general policy issues (death penalty, abortion) and those more salient to Latinos (immigration, bilingual education), I test the primary hypothesis that group consciousness has a greater impact on Latino political attitudes when the issues are directly tied to ethnicity Group consciousness is a multi-dimensional concept developed when members of a group recognize their status as being part of a deprived group (Miller et al. 1981). To investigate the relationship between group consciousness and Latino public opinion this investigation utilizes four separate empirical models, one for each issue area; abortion, death penalty, bilingual education, and immigration. The data used in this investigation originates from the 1999 survey of 2,417 Latinos conducted by the Washington Post, The Henry J. Kaiser Family Foundation, and Harvard University A review of the extant literature on the role of group consciousness in the formation of political attitudes will follow a discussion of the current literature of Latino public opinion to provide a theoretical foundation for this investigation of the impact of group consciousness on Latino policy preferences.


Abstract Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency could be a risk factor for diabetes, as suggested by various epidemiological data, but still a matter of debate. The occurrence of haemolysis during diabetes crises was reported in patients with G6PD deficiency, furthermore the fall in glucose level during the treatment of hyperglycemia is suggested as a possible cause for hemolysis in G6PD deficiency. We reviewed the mechanisms that may link the two diseases. Clinical Case: A 19-year-old male, with G6PD deficiency, presented to the emergency department in our institution with history of generalised weakness, epigastric pain, nausea, and vomiting. He gave history of polyuria, polydepsia and weight loss over a period of two weeks. Diagnosis of DM was confirmed by laboratory tests that showed a mild DKA: arterial pH 7.28, HCO3 18 mmol/l, plasma glucose 21 mmol/l, urinary ketones ++, and hemoglobin 16.1 g/dl (12.0–15.0 g/dl). DKA was treated according to DKA guidelines. Ketoacidosis remission was achieved two days after rehydration and treatment with continuous intravenous insulin infusion (0.05–0.1 IU/kg). The patient then started on subcutaneous intensive insulin injection therapy, three times daily before meals and once before bedtime. Fasting and post-prandial blood glucose levels decreased to 7-8mmol/L, and 10 –13 mmol/l respectively. On day 4, the patient developed dizziness while he was taking a bath, On examination he was pale and had icterus, however, the vital signs and systemic examination were normal, blood tests revealed a hemolytic anemia as follows: (normal values): Hemoglobin 9 g/dl (12.0–15.0 g/dl), reticulocytes 8.5% (0.5–1.5%), total bilirubin 82 umol/l (0–20 umol/l), unconjugated bilirubin 58 umol/l (3–15 umol/l), By the 7th day, hemoglobin levels had fallen to the lowest value of 8.3, then gradually raised to 10.2 g/dl, 2 weeks later, hemoglobin electrophoresis was normal, Coombs test was negative. G6PD activity was below 300 U/L (reduced activit<600) with two separate measurements. The patient had no bacterial infections and had not ingested haemolytic drugs. Hemolysis ceased spontaneously and hemoglobin increased gradually. Conclusion: G6PD deficiency and diabetes mellitus could aggravate each other, and In patients at risk of G6PD deficiency screening of the enzyme activity should be considered following diabetes decompensation, and in case of G6PD deficiency, it is advisable to correct plasma glucose level gradually to avoid the rapid drop in glucose availability, which may cause hemolysis in these patients.


A method is presented for determining the coefficient of transverse dispersion in flow through packed beds, which is based on the measurement of the rate of dissolution of planar or cylindrical surfaces, buried in the bed and aligned with the flow direction. The underlying theory is initially explained and experiments are then described in which more than three hundred new data points were obtained. These data are for the flow of water, at interstitial velocities between 0.1 and 1.5 mm/s, through beds of silica sand with average particle sizes between 0.219 and 0.496 mm. The experiments were performed at a range of temperatures, between 20oC and 35oC, and this yielded dispersion data for values of the Schmidt number (Sc=μ /ρDm) between 1170 and 570. For all the data reported, the ratio between the coefficient of transverse dispersion and the coefficient of molecular diffusion was shown to correlate well with the Reynolds number (Re=udρ /μ), both for beds with narrow and with wide particle size distributions.

The experimental animals were divided into medication group,control group and normol group,and the effect of Dendrobium denneanum polysaccharide on mice(rats) with alloxan-induced hyperglycemia was investigated by applying different doses(300,100,30 mg/kg).The results showed that D.denneanum polysaccharide was able to reduce blood glucose level of mice with alloxan-induced hyperglycemia mice and increase glucose tolerance of rats with alloxan-induced hyperglycemia.On the other hand,it was found that D.denneanum polysaccharide had no significant influence on the serum glucose level of normol mice and the glucose tolerance of normol rats.The study indicates that D.denneanum polysaccharide has significant effects of hypoglycemic action on diabetes mellitus mice and the polysaccharide is worthy to be utilized to develop medicines for diabetes mellitus.Tab 6,Ref 10


This paper examines the impact that development theories have had on development policies, and the inverse impact of actual successes and failures in the global South on development thinking. It is argued that development thinking is at the cross-roads. Development theories in postwar period went through a full circle – from Big Push and ISI to neo-liberal Washington consensus to the understanding that neither the former, nor the later really works in engineering successful catch-up development. Meanwhile, economic miracles were manufactured in East Asia without much reliance on development thinking and theoretical background – just by experimentation of the strong hand politicians.


Dysfunction of γ-aminobutyric acid A (GABAA) receptors (GABAARs) is a prominent factor affecting intractable epilepsy. Plic-1, an ubiquitin-like protein enriched in the inhibitory synapses connecting GABAARs and the ubiquitin protease system (UPS), plays a key role in the modification of GABAAR functions. However, the relationship between Plic-1 and epileptogenesis is not known. In the present study, we aimed to investigate Plic-1 levels in patients with temporal lobe epilepsy, as well as the role of Plic-1 in regulating onset and progression of epilepsy in animal models. We found that Plic-1 expression was significantly decreased in patients with epilepsy as well as pilocarpine- and pentylenetetrazol (PTZ)-induced rat epileptic models. Intrahippocampal injection of the PePα peptide, which disrupts Plic-1 binding to GABAARs, significantly shortened the latency of seizure onset, and increased the seizure severity and duration in these two epileptic models. Overexpressed Plic-1 through lentivirus transfection into a PTZ model resulted in a reduction in both seizure severity and generalized tonic-clonic seizure duration. Whole-cell clamp recordings revealed that the PePα peptide decreased miniature inhibitory postsynaptic currents (mIPSCs) whereas overexpressed Plic-1 increased mIPSCs in the pyramidal neurons of the hippocampus. These effects can be blocked by picrotoxin, a GABAAR inhibitor. Our results indicate that Plic-1 plays an important role in managing epileptic seizures by enhancing seizure inhibition through regulation of GABAARs at synaptic sites.


We present the results of a combined experimental and theoretical investigation of phase separation and microstructure development in co-deposited Al–Ge thin films. For small film thicknesses and deposition temperatures above 150 °C the phase-separated films consist of an array of domains of the Al- and Ge-rich terminal phases (lateral phase separation). Films deposited at 100 °C or less contained one or both of the terminal phases plus a metastable phase. We show that the domain structure evolves during deposition in a manner consistent with a surface interdiffusion controlled process. As film thickness increases we observe a transition from the laterally phase-separated microstructure to a layered microstructure exhibiting phase separation perpendicular to the film/substrate interface (transverse phase separation), with Al segregating to the film surface. We present a thermodynamic argument based on the competition between surface and interfacial free energies to explain this transition. Finally, we discuss the stability of the transverse phase-separated microstructure in the thick-film limit in terms of the transport of Ge through the Al-rich surface layer.


Background and Objective: The acquisition and dissemination of antibiotic-resistant agents in Acinetobacter baumannii (A. baumannii) is highly facilitated through integrons that are DNA transposable elements and able to receive genes through site-specific recombination. Class 1 and 2 integrons are the most known integrons that are frequently available in A. baumannii. The aim of this study was to determine the frequency of class 2 integron in multidrug resistance (MDR) A. baumannii. Methods: A total of 100 isolates of A. baumannii were collected from patients that are admitted to hospitals in Kermanshah in the year 2014-2015. The isolates were identified using biochemical tests and the kit API 20 NE, and then their sensitivity to 20 antibiotics was examined. The prevalence rate of class 2 integrons among the isolates was determined using Polymerase chain reaction (PCR). The results were analyzed using Fisher's test and the non-parametric Chi-squared test. Results: The maximum drug resistance was observed against Cefotaxime (93%), Ceftriaxone (92%), Mezlocillin (91%), Ceftazidime (86%), Imipenem (82%), and Piperacillin (82%). The minimum drug resistance was observed against Colistin (12%), Polymyxin B (7%), Minocycline (10%), and Tigecycline (6%) and seems as the most efficient antibiotics. Twenty-nine (29%) isolates out of the 100 isolates were multidrug resistance (MDR); about 21 isolates (21%) were extensive drug resistance (XDR); and none were pan drug resistance (PDR). Thirty four (34%) isolates contained class 2 integrons. The results did not showed a significant correlation between the presence of class 2 integrons and incidence of MDR A. baumannii. Conclusion: The transmission of antibiotic-resistant agents by the class 2 integrons resulted in further durability and spread of these isolates in the environment. Therefore, it seems that resistance to A. baumannii is always changing, and different countries should attend to these changes.


In this contribution a fuzzy object-based data model for imperfect spatial information is proposed within the formal framework of fuzzy set theory and possibility theory. The proposal integrates the two opposite views of geographic entities seen as either exact objects or continuous fields in current Geographic Information Systems. By assuming a Fuzzy Object-Oriented Data modelling approach new data types for representing geographic entities characterized by either unsharp boundaries or indeterminate boundaries and relationships are defined.Linguistic qualifiers are adopted both to express the extent by which an element of the spatial domain satisfies a gradual property, and to identify regions with indeterminate boundaries.


Al2O3 particles reinforced ZL109 composites were prepared by in-situ reaction between Fe2O3+MnO2 and Al in this paper. The influence of ratio of Mn to Fe on the morphologies of Al-Si-Mn-Fe phase and mechanical properties of the composites was investigated. The microstructure was studied by electron probe micro-analyzer (EPMA) and transmission electron microscopy (TEM). The results show that the Al2O3 particles displaced by the Fe2O3+MnO2/Al system are in nanosize. The acicular Al-Si-Fe phases change from acicular to polygonal shape and become smaller with the increase manganese content. The hardness test results have no big difference on the composites. However, the ultimate tensile strength at room temperature and 350°C enhance evidently with the increasing of Mn/Fe.

The policies and practices of higher education are reeling under the social, economic, and technological changes currently taking place in post-industrial, information societies. New communications and information technologies are constitutive factors in the philosophical and pedagogical shifts that are occurring in university classrooms. This paper uses a case-study methodology to investigate the use made of online technologies in one preservice teacher education context. Cyber technologies and their associated pedagogical activities are conceptualized in the paper not only as tools, but also as social practices. This approach enables a focus on learning and teaching as transformative practices. Following a description of the course content and delivery, the paper turns to an analysis of four key pedagogical features of cyber pedagogy as generated by the data. These are: Teaching and Learning as Self-directed Activity, Change in Student Identities and Self-perceptions, New forms of Technoliteracies, and E-tutorials. The research found that online pedagogies are forming new spatialities, multiliteracies, and identities of communication and learning.

A Nafion/ruthenium oxide pyrochlore (Pb 2 Ru 2-x Pb x O 7-y ) chemically modified electrode (CME) for the determination of uric acid by Osteryoung square-wave voltammetry (OSWV) is described. Compared to the glassy carbon electrode, the CME exhibits a 150 mV shit of the oxidation potential of uric acid in the cathodic direction and a marked enhancement of the current response. The best instrumental settings for OSWV are 50 Hz modulation frequency, 20 mV modulation amplitude, and 2 mV step height. Linear calibration curves are obtained over the 7.5×10 -5 -5×10 -7 M range in pH 1 buffer solution. The detection limit (3) is 1.1×10 -7 M. Ascorbic acid in less than 10-fold excess does not interfere. The practical analytical utility is illustrated by selective measurements of uric acid in human urine and serum without any preliminary treatmen


In the last decade, the renaissance of interest in discriminant analysis has been primarily motivated by possible applications to tumor classification using highdimensional microarray-based data. In this thesis, we do three things: 1. First, we introduce a new regularizing covariance estimation procedure we refer to as SHIP: SHrinking and Incorporating Prior knowledge. The resulting covariance estimator is based on the shrinkage estimator by Ledoit and Wolf [31, 33, 32], but additionally incorporates prior knowledge on gene functional groups extracted from the database KEGG. In order to integrate this knowledge into the shrinkage estimator, we develop multiple options. Instead of using a standard cross-validation procedure for determining the optimal shrinkage intensity, we determine it analytically as introduced by Ledoit and Wolf. 2. Second, we propose a variant of regularized linear discriminant analysis. This method generalizes the idea of the shrinkage estimator from above into the linear discriminant analysis (LDA). 3. Third, we apply our method to public gene expression data sets and examine the classification performance in both the binary and the c-nary case, where c > 2. We choose the diagonal linear discriminant analysis and the nearest shrunken centroids method [15] as competitors. It is shown that the rlda.TG one of our variants of LDA 'via the SHIP' performs well in all classification problems and even outperforms, albeit marginally, the competitors in some situations. Unexpectedly, we find that another variant of LDA which is based on the shrinkage estimator by Ledoit and Wolf and which does not incorporate any biological knowledge is as competitive as the rlda.TG.


CdS nanoarods have been synthesized by using Cetyltrimethyl Ammonium Bromide (CTAB) as the soft template under γ-irradiation through the reaction of cadmium sulphide (CdSO4·8/3H2O) and thiacetamide (TAA) in acidic condition for pH value of 3. The physical and chemical properties and the structure of CdS nanorods were characterized by XRD, UV-Vis, SAED, TEM and PL. The results indicate that CdS nanorods synthesized by soft template method are below 100 nm in diameter and above 3 nm in length, and low irradiative dosage and concentration of reactants can accelerate the formation of CdS nanorods with higher length-to-diameter factor about 30:1 range.


Abstract This article analyses from a historical perspective the relationships between art, photography, and feminism in the Italian cultural context of the 1970s, in order to shed light on a chapter of Italian historiography that has been explored only marginally. During this decade, photographic practice and feminist thought formed a close connection: many artists who were active in awareness-raising groups or embraced feminist theories chose photography as their expressive means both for its ability to grasp issues relating to subjectivity and the body, and as a tool to demystify the stereotypes linked to the gender difference widespread in Western visual culture. Photography became the privileged means adopted by these artists to criticize the symbolic order of the dominant language and its masculine inflection. In a historical moment in which women struggled to overturn the canons of patriarchal culture, photography, with its specific indexical nature and its relationship of adherence to external reality, also allowed these artists to construct a radical social criticism of the way images were used to portray femininity, to challenge the centuries-old invisibility of women's experiences, and to deconstruct the mechanisms of fetishization and eroticization characterizing the representations of the female body.


In this paper, we consider the behavior of plane shock waves in deformable magnets which are electrical insulators. We assume that the stress and the magnetic field depend on the strain and the magnetization. In addition to deriving the differential equation which governs the behavior of the shocks, we also give explicit formulae for the changes in magnetization across the shocks. After discussing the implications of these results, we consider the special case when each component of the magnetic field depends oi1 the strain and the component of the magnetization which is parallel to it. The results corresponding to this ease should be of special interest to experimentalists.


Creatine amidinohydrolase (creatinase) catalyzes the hydrolysis of creatine to urea and sarcosine by a proposed mechanism involving only non‐covalent forces of attraction. The enzyme is important in creatine metabolism in several bacteria and its increased activity has been linked to Duchenne Muscular Dystrophy in humans. Structural analyses of creatinase have provided insight concerning the potential catatlytic roles of specific side chains. To appreciate the power of creatinase as a catalyst, quantitative information of the rate of uncatalyzed hydrolysis of creatine in a rage of pH‐buffered solutions will be measured at elevated temperatures. The extent of reaction will be determined using 1H‐NMR and UV spectroscopies. Linear extrapolations from an Arrhenius plot will estimate the rate of hydrolysis at 25 °C to compare with the enzyme‐catalyzed reaction. Catalytic rate enhancement (kcat/knon) and proficiency (kcat/Km/k non) will be reported. Initial data suggest a relatively rapid, pseudo‐first order rate of hydrolysis of creatine at 180 °C.

The Gogebic Iron Range extends for some 100 km from near Clam Lake, northwestern Wisconsin to Lake Gogebic, westernmost northern Michigan. It consists of an allochthonous package of Early Proterozoic (EP) strata sandwiched between Archean basement rocks on the south and unconformably overlying Middle Proterozoic (MP) Keweenawan strata on the north. Volcanic rocks occur at either end of the Gogebic range, but the central part of the range consists mainly of monoclinically north-dipping sedimentary strata. Initial phases of Penokean deformation detached Early Proterozoic strata from underlying Archean basement and created northverging, bedding-parallel shears in the monoclinal sequence. Exposures of mylonitized rocks at several places along the length of the district demonstrate the allochthonous nature of EP strata. The main zones of detachment are the shaly portions of the Sunday Quartzite and Palms Formation. Bedding and the shear zones were next deformed into northeast and northwest-plunging folds, most prominently at the east and west ends of the range respectively. Subsequent deformation involved faulting of both the Archean and EP strata. During formation and closure of the MP Midcontinent Rift, the Pre-Keweenawan strata were tilted steeply northward along listric thrusts (Cannon et al, 1993), resulting in a northwestern-oriented, strike-parallel, cross-sectional view ofmore » the Pre-Keweenan crust.« less


Using a visual-to-auditory sensory-substitution algorithm, congenitally fully blind adults were taught to read letters and words using 'soundscapes' — sounds topographically representing images. High resolution fMRI was used to examine key questions regarding the neurochronometry of the reading process in the blind: the areas which are involved in the reading network of the blind in the different phases of the process and the onset latencies of the different areas participating in the network. The central foci of the reading network of the blind were found to be a subset of the areas involved in the reading of degraded stimuli. Further, the onset of the reading process begins in the auditory cortex and then moves to occipital cortex and roughly follows the processing hierarchy expected in the sighted individuals.


A new enzyme reactor system for low-molecular-weight substrates, utilizing forced flow through an enzyme-immobilized membrane, was developed. Invertase was physically immobilized within a porous ceramic membrane by filtering an enzyme solution, and a sucrose solution was forced through the membrane by pressure, using a crossflow filtration method. The reaction rate of the forced-flow system was more than 10 times greater than that observed in a diffusion-controlled system. The reaction rate in both systems was mathematically modeled, and the simulated results were in good agreement with the experimental results. The reaction rate in the forced-flow system was easily controlled by pressure, and its productivity was greater than those reported in other reactor systems.


Sandia National Laboratories/New Mexico (SNL/NM) is managed and operated for the U.S. Department of Energy (DOE) by Sandia Corporation, a subsidiary of the Lockheed Martin Company. SNL/NM is located on land controlled by DOE within the boundaries of Kirtland Air Force Base (KAFB) in Albuquerque, New Mexico. The major responsibilities of SNL/NM are the support of national security and energy projects. This report provides an environmental assessment of proposed remedial action activities at the solid waste management units at SNL/NM. A risk assessment of health hazards is also discussed.


The invention discloses a method for adjusting the jacking force of a tail bracket of a crankshaft grinding machine. The method comprises the following steps of: arranging a set of hydraulic driving mechanism on the tail bracket of the crankshaft grinding machine; driving a main shaft of the tail bracket by using hydraulic pressure; detecting the pressure used for driving the main shaft of the tail bracket; adjusting oil supply pressure according to a detection result; when a preset pressure value is reached, sending a command out to stop continuously increasing the oil supply pressure; and keeping the pressure constant by using an energy accumulator. In the method, due to the additional arrangement of the set of hydraulic driving mechanism on the tail bracket of the crankshaft grinding machine, the jacking force of a machined crankshaft can be accurately and appropriately adjusted, so that larger deformation is prevented from being generated under the action of the jacking force, and the machining deformation of parts which is generated by reduced contact stiffness due to insufficient jacking force can be prevented simultaneously. The method is suitable for the crankshaft grinding machine or other machine tools which meet requirements similar to the operation requirements of the crankshaft grinding machine.


The field experiments were conducted at Agricultural Research Station, Ummedganj, Kota during kharif 2007 and 2008 to develop suitable organic module strategies on soybean crop. Five organic modules along with some common practices/applications such as Deep summer ploughing + Seed treatment with Trichoderma viridae @ 6 g/ha + Installation of "T" shape bird perches + Spray of Azadirachtin 1500 ppm @ 2.50 1/ha at 15 days after sowing were evaluated for their efficacy against predominant insect pests e.g. green semilooper Chrysodeixis acuta Walker and girdle beetle Obereopsis brevis Swed. The organic module Ma (Plucking of infested plant parts + release of Trichogramma @ 1.0 lac/ha at 30 DAS + B.t. at 50 DAS) was found most effective against green semilooper and girdle beetle wherein minimum green semilooper and girdle beetle population (0.72 larvae/m and 1.66%), maximum seed yield (1160 kg/ha) and higher IBCR (4.54) was recorded. The next best module was M4 (Plucking of infested plant parts + two release of Trichogramma at 30 & 40 DAS + B.t. at 50 DAS) recorded 0.93 larvae/m row length of green semilooper population, 2.50% infestation of girdle beetle, 1122 kg/ha seed yield and IBCR (3.71).


Koongol and Wongal virions are isometric, enveloped, and 90-100 nm in diameter. They develop by budding into smooth-surfaced vesicles in or near the Golgi region of the cytoplasm of infected cells. In morphology and morphogenesis they thus resemble other members of the Bunyamwera supergroup of arboviruses.


Type 1 diabetes mellitus (DM1) is associated with compromised (defective) immunologic tolerance to autoantigens and selective destruction of pancreatic B-cells by CD4+ (effector) and CD8 (cytotoxic) lymphocytes. The mechanisms of autotolerance involve CD4+CD25+high T-regulatory cells (Treg) whose suppressor activity depends on the expression of the FoxP3 gene. Aim. Detection of quantitative and functional alterations at the level of regulation of immunity in subjects at risk of DM1 and patients with different duration of DM1. Materials and methods. 116 patients (67 men and 49 women) with different duration of DM1. The risk group was comprised of 33 subjects (10 men and 23 women), control group included 16 subjects. In all cases, HLA genotyping was performed, autoantibodies to GDC, insulin and tyrosine phosphatase, islet cell antigens were determined, subpopulation composition of CD3+, CD4+, CD8+, CD38+, HLA DR+, CD25+, CD4+25+ lymphocytes and their functional activities (FoxP3 gene expression) studied, C-peptie and HbA1c levels measured. Results. A tendency toward a rise in Cd25+ and CD4+25+ T-lymphocytes and a decrease in FoxP3 expression was documented in the risk group compared with control (p0.05) but their functional activity was lower (p

AA 6061 is used in the automotive, aircraft, marine and construction industries due to it is excellent properties
such as noncorrosive, strength to weight ratio and rewards over than steel in ductility. Four groups of particle size were
chosen (25, 63, 100, mix) μm. Each group has compacted by three specimens for various of Sintering temperature (487,
552, 617) OC, the compaction pressure and holding time were constant (9) tons, (20) min respectively. The mechanical
properties of the four groups depend on the variations of sintering temperature. So, it is useful first to present and discuss
the results of microstructure to understand the strengthening mechanism. In this study, compression strength value was
increased with the increasing of sintering temperature value to (552) OC of all types of suggested groups due to the bonding
between particles was stronger, in addition, the pores amount was decreased. After that, it was decreased due to the
particles become big size lead to the barriers were decreased. The maximum value of compression strength was detected by
mix group which was (160) MPa while the particle size (100) μm was the minimum value which was (115)MPa. Where as
the groups (25) μm and (63) μm were (150) and (134)MPa respectively.


firstname.lastname@example.com Abstract The International Union of Biochemistry (IUB, now IUBMB) prepared recommendations for describing the kinetic behaviour of enzymes in 1981. Despite the more than 30 years that have passed since these have not subsequently been revised, though in various respects they do not adequately cover current needs. The IUBMB is also responsible for recommendations on the naming and classification of enzymes. In contrast to the case of kinetics, these recommendations are kept continuously up to date. & 2014 The Author. Published by Elsevier GmbH.

Baima Tibetan folk songs are an integral part of the Baima Tibetan music culture. They are performed in diverse styles, including solo, duet, lead singing, round singing, and chorus. The objective of the study was to explore the significance of Baima Tibetan folk songs as a resource for literacy education in Chinese music history. By engaging with key informants divided into three groups - scholar informants, casual informants, and general informants. The result of this study reveals that ritual music holds deep roots in religious beliefs and is performed during sacrificial ceremonies, marriage ceremonies, and funeral ceremonies. Dance music culture reflects the collective nature and community cohesion of the Baima people, with dances like the fire circle dance serving as prominent expressions. Folk songs encompass a wide range of themes, including labor, wine, wedding, and love, showcasing the diverse musical expressions within Baima Tibetan society. The unique rituals, dances, and songs of the Baima people contribute significantly to the preservation and celebration of their rich cultural heritage. This study highlights the educational potential of Baima Tibetan folk songs as valuable resources for promoting literacy and understanding in the context of Chinese music history.


The Ediacaran biota is profoundly mysterious. There is a growing realization that these organisms should not be grouped in a single taxon, such as Petalonamae or Vendobionta, but debate continues on what the group as a whole represents. It is argued here that the Ediacarans constitute a broad, megascopic, paraphyletic grade of organization which overlaps the stem groups (and perhaps some crown groups) of the Porifera, Ctenophora, Cnidaria and Bilateria. The modular organization of many Ediacarans suggests that they were fundamentally colonial organisms. The early disc‐shaped forms may have been solitary individuals, perhaps with a choanoflagellate or simple sponge‐like grade of organization; the modular forms may represent bud colonies of those entities. The more complex fronds, as well as other segmented and bilaterally symmetrical Ediacarans, seem to exhibit a trend toward higher levels of integration and individuation. This trend is comparable to those observed among more recent colonial organisms. Interpretation of modular Ediacarans as colonial organisms leads to a new perspective on the evolution of metazoans. It suggests that the earliest solitary Ediacarans furnished a framework for the development of cell and tissue specialization, including the formation of epithelia and complex connective tissues. Later colonial forms provided a mechanism to increase nested or hierarchical complexity, through duplication, integration, and individuation. Early acquisition of complexity had a profound impact on the subsequent evolution of metazoan body plans. The Ediacarans seem to have evolved the range of colonial forms required to give rise to the radiation of complex bilaterians in the Cambrian. If this is true, it obviates the need to postulate the existence of the microscopic, acoelomate ancestors of basal metazoan taxa that are required by prevailing hypotheses bearing on the early evolution of the Metazoa.


We have conducted a V-band CCD surface photometry of 68 disk galaxies to analyze the bulge morphology of nearby spirals. We classify bulges into four types according to their ellipticities and the misalignments between the major axis of the bulge and those of the disk and the bar: spherical, oblate, pseudo triaxial, and triaxial. We found that one third of the bulges are triaxial and they are preponderant in barred galaxies. The presence of the triaxial bulges in a significant fraction of unbarred galaxies as well as in barred galaxies might support the secular evolution hypothesis which postulates that the bar driven mass inflow leads to the formation of triaxial bulges and the destruction of bars when sufficient mass is accumulated in the central regions.

 Telemedicine, which came into existence in its organized form in the late 1950s and promised to be at the forefront of the future of medicine, has not achieved the estimated success yet. It makes state-of-the-art healthcare highly accessible for everyone. However, the reality is that the concept has been adopted by only a handful of nations and for many of them, it has remained merely as a concept. This can be attributed to the lack of proper supportive infrastructure and awareness, reimbursement issues and legal restrictions. The ongoing global health crisis of COVID-19 has forced the regulatory bodies and healthcare providers to look for alternative healthcare service delivery modes and, telemedicine is being considered more and more as an ideal solution. In a state of complete lockdown, it allows remote consultation without any face-to-face contact, thus preventing any unnecessary exposure to an infection. Various national bodies and organizations such as The Academy of Family Physicians and the American Medical Association (AMA), besides the government of different nations including India, have released relevant telemedicine guidelines. It is a readily available solution especially for individuals on chronic medications for non-communicable diseases in addition to filtering out potential COVID-19 cases remotely. The pandemic has brought telemedicine into the limelight and it is the right time to strengthen the framework and incorporate additional features and services to make it disaster-ready for all times. Various aspects and opinions about the future of telemedicine and telehealth have been put forward here pivoting around the experiences at a telemedicine center in India. Can telemedicine have a significant impact on R-naught (R0) by cutting its right-side tail and pushing it below 1, thus contributing to the flattening of the COVID-19 curve? Our fight against public health crises in the future would rest a lot on this answer.


In this paper the authors describe an experimental investigation to determine the electrical transfer characteristics of electro-rheological fluids in the squeeze-flow mode of operation. It has been shown previously that the squeeze-flow mode provides significantly greater mechanical forces than are available from ER fluids placed in shear. However, since the electric field varies as a function of the inter-electrode gap there is an additional need to understand the complex elec trical/mechanical interactions at work in squeeze-flow. The study confirms the need to account for the dynamics of the electrical source and shows how the frequency dependence of the capacitive and resistive terms associated with the squeeze-flow cell can be quantified through the use of suitable empirical expressions. The validity of the derived coefficients is demonstrated through the ability of models to predict the complex admittance transfer function of the ER squeeze-flow cell.

Several drought indices such as Deciles and Standardized Precipitation Index (SPI) had been used in the past to assess drought conditions and to trigger drought responses. However, they were based on rainfall as the single variable which does not adequately represent the variety of drought conditions. In this paper, the development of a Nonlinear Aggregated Drought Index (NADI) by considering significant components of the water cycle is presented. The NADI was used to assess the historical drought conditions of the Yarra River catchment in Victoria (Australia). Nonlinear Principal Component Analysis was introduced and used in this study as the numerical approach to aggregate hydrometeorological variables which describe the fluctuations in the hydrologic cycle into NADI. The NADI results were compared with those of Deciles (used commonly in Australia) and SPI (used in most parts in the world). The results showed that the NADI was more robust than Deciles and SPI. The main advantage of NADI is the assessment of droughts from the aggregate perspective of meteorological, hydrological, and agricultural water shortages.


. Let W be a finite Coxeter group. We give an algebraic presentation of what we refer to as "the non-crossing algebra", which is associated to the hyperplane complement of W and to the cohomology of its Milnor fibre. This is used to produce simpler and more general chain (and cochain) complexes which compute the integral homology and cohomology groups of the Milnor fibre F of W . In the process we define a new, larger algebra e A , which seems to be "dual" to the Fomin-Kirillov algebra, and in low ranks is linearly isomorphic to it. There is also a mysterious connection between e A and the Orlik-Solomon algebra, in analogy with the fact that the Fomin-Kirillov algebra contains the coinvariant algebra of W . This analysis is applied to compute the multiplicities h ρ, H k ( F, C ) i W and h ρ, H k ( M, C ) i W , where M and F are respectively the hyperplane complement and Milnor fibre associated to W and ρ is a representation of W .


KARI, the elephant, was five months old when he was given to me to take care of. I was nine years old and I could reach his back if I stood on tiptoe. He seemed to remain that high for nearly two years. Perhaps we grew together; that is probably why I never found out just how tall he was. He lived in a pavilion, under a thatched roof which rested on thick tree stumps so that it could not fall in when Kari bumped against the poles as he moved about.


Abstract In traditional satellite navigation receivers, the parameters of tracking loop such as loop bandwidth and integration time are usually set in the design of the receivers according to different scenarios. The signal tracking performance is limited in traditional receivers. In addition, when the tracking ability of weak signals is improved by extending the integration time, negative effect of residual frequency error becomes more and more serious with extension of the integration time. To solve these problems, this paper presents out research on receiver tracking algorithms and proposes an optimised tracking algorithm with inertial information. The receiver loop filter is designed based on Kalman filter, reducing the phase jitter caused by thermal noise in the weak signal environment and improving the signal tracking sensitivity. To confirm the feasibility of the proposed algorithm, simulation tests are conducted.


Despite pain prevalence altering with age, the effects of aging on the properties of nociceptors are not well understood. Nociceptors, whose somas are located in dorsal root ganglia, are frequently divided into two groups based on their ability to bind isolectin B4 (IB4). Here, using cultured neurons from 1‐, 3‐, 5‐, 8‐, 12‐, and 18‐month‐old mice, we investigate age‐dependent changes in IB4‐positive and IB4‐negative neurons. Current‐clamp experiments at physiological temperature revealed nonlinear changes in firing frequency of IB4‐positive, but not IB4‐negative neurons, with a peak at 8 months. This was likely due to the presence of proexcitatory conductances activated at depolarized membrane potentials and significantly higher input resistances found in IB4‐positive neurons from 8‐month‐old mice. Repetitive firing in nociceptors is driven primarily by the TTX‐resistant sodium current, and indeed, IB4‐positive neurons from 8‐month‐old mice were found to receive larger contributions from the TTX‐resistant window current around the resting membrane potential. To further address the mechanisms behind these differences, we performed RNA‐seq experiments on IB4‐positive and IB4‐negative neurons from 1‐, 8‐, and 18‐month‐old mice. We found a larger number of genes significantly affected by age within the IB4‐positive than IB4‐negative neurons from 8‐month‐old mice, including known determinants of nociceptor excitability. The above pronounced age‐dependent changes at the cellular and molecular levels in IB4‐positive neurons point to potential mechanisms behind the reported increase in pain sensitivity in middle‐aged rodents and humans, and highlight the possibility of targeting a particular group of neurons in the development of age‐tailored pain treatments.


99m Tc(CO)3-(C60(OH)22) have shown that the labelling yield, in alkaly media, was 95.35%. Protein binding to HA was species-dependent process. The biological behaviour of labelled fullerenol were different in dependence of labelling method and the time of sacrificed of animals. From recent investigations it can be concluded that oxidation state in technetium coordination complexes has a great impact on in vitro and in vivo behaviour of the these complexes.

Low birth weight is a major determinant of mortality, morbidity and disability in neonates, infancy andchildhood, Therefore improvements in maternal nutrition and health can increase birth weight, survival and growthof the child including subsequent size and health productivity in adult life. The mother needs an additional intake of nutrients to achieve optimal fetal growth. This additional intakeis 300 kcal per day more than the normal needs of a non-pregnant woman, that is, a minimum intake of 2,500kcal per day. As previously, the favored hypothesis was that timing maternal supplementation during the third trimesterof pregnancy would be most likely to increase birth weight. The rationale was that fetal fat deposition was fastestduring this stage of pregnancy. In earlier trimesters, when maternal fat is increasing fastest, supplementation wouldbe more likely to benefit maternal weight gain. Subsequent research contradicts this hypothesis, however, and suggeststhat nutrition intervention earlier in pregnancy will have the strongest effect on birth weight. There is evidence to support the effectiveness of calcium supplementation for a reduction in preterm birthand the incidence of low birth weight in pregnant women, this effect was strongest in women with lower calciumintakes (<900 mg per day), and that preterm delivery was reduced in women at high risk of developing hypertension. Key words: Low birth weight, Nutrition supplementation


The purpose of this study is to adapt Goal Orientations for Teaching Scale into Turkish upon carrying out relevant reliability and validity assessments on the scale. The study group is comprised of 584 teachers. The original scale (Goal Orientations for Teaching) consists 5 factors and 21 items, whereas as a result of exploratory factor analysis in scope of present study, 4 factors with 1 or greater eigen value have been established. Out of these factors, reliability value of the Skill Orientation factor was found to be α=.787 and its variance %24.56; reliability of Mastery factor at α=.638 and variance at %15.70; reliability of Avoidance factor at α=.605 and variance at %8.06; reliability of Student Relations factor at α=.673 and variance at %6.72; and reliability of entire scale was found to be at α=.761 and its variance at %55, respectively. Moreover, exploratory factor analysis indicated that the 4-factor and 15-item scale possesses plausible adaptive values (χ2/sd=1.43; RMSEA=.027; GFI=.98; AGFI=.96; CFI=.98; TLI=.98). The 4-factor and 15-item Turkish version of the scale, original of which contains 5 factors and 21 items in English, was found to be both reliable and valid. It was concluded that the adapted scale could be used to determine teachers' goal orientations towards teaching.


The Grapsoid crabs heretofore recorded from China are represented by 80 species,32 genera and 4 subfamilies.In the present paper,notes are given on the geographical distribution,taxonomic characters as well as characteristics of fauna of the Chinese Grapsidae.The distribution of the Chinese Grapsidae is shown in Table 1.In accordance with the adaptive thermal nature of the crabs,they may be classified into three types:the warm-water species,the warm-temperate species and the coldthemperate species in the proportion of 85%,13.8% and 1.2%.A comparison of Grapsoid crabs from the South China Sea,Bast China Sea and Yellow Sea is shown in table 2.The Grapsoid species of China are also compared with those of the Indo-West Pacific region,which may be sub-divided into ten units (Pig.1),namely "East Africa","India","South-East Asia","Southern Japan","Northern Japan","West coast of Korea","Bast coast of Korea","Par eastern sea,of U.S.S.E.","Pacific" and"Oceania",using a coeffecient of faunistic similarity,as pro-posed by Barnes (1968).The results are shown in table 3.Differences in genital strustures are considered to be most significant among the morphological characters ?of some Grapsoid crabs.Geographical and ecological characteristics are also of practical importance for classification.


The study rationalized how development projects implemented through religion engagement (RE) implicates satisfactorily attaining gender equality. Reorganized establishment based on secondary data analyzed using qualitative and quantitative techniques found how social development projects implemented through RE increased gender equality, thus reducing gender gap index. And this is evidenced by how the gender gap index in Tanzania declined from 0.652 to 0.537 between 1995 and 2017. However, it was high, as by 2022 the gender gap index recorded 0.72 in Tanzania. This attributed by several factors, including agricultural and livestock development projects, increased gender inequality as men dominate more than women, and causal factors are that women lack capital and are inaccessible to credit services as they lack mortgage assets. The conclusion shows development projects implemented through RE are significantly increasing gender equality, but a gap remains a crucial problem facing Tanzanians and recommendations geared to policy makers to employ effective policies and adopt practical modalities.

The problem of scheduling customers in a multiclass G/G/1 queue is addressed so as to minimize a weighted sum of the work-loads of the different classes. It is established that the nonidling preemptive fixed priority policy that schedules customers belonging to the class having the maximum weight, minimizes the cost function pathwise at any point in time. This result is based on the application of elementary forward induction arguments and is shown to hold for a very general class of policies. A proof for the optimality of the mu c-rule in the multiclass G/M/1 queue is then obtained as an easy corollary of the first result.<<ETX>>


A well-established rabbit model infected with reference strain of enteropathogenic E. coli (EPEC) {E coli O103:K-:H22 (E22)} was used to examine whether vitamin C (VC) nutritional supplementation had an effect on the pathological changes induced in the bowel by EPEC{E. coli O103:K-:H22 (E22)}. In this study artificial infection model, weaned female rabbits were infected with E. coli O103:K-:H22 (E22) and infected tissues were evaluated by light microscopy. Twenty-three rabbits were used in this study. They divided into five groups(first group of rabbits  were used as control (3 rabbits), second group were treated with vitamin C (60mg/kg) in drinking water (5 rabbit),third group were infected with E. coli {O103:K-:H22 (E22)} (5 rabbits) ,fourth group of rabbits infected with E. coli {O103:K-:H22 (E22)} and treated with vitamin C (60mg/kg) in drinking water (5 rabbits),and fifth group were infected with E. coli {O103:K-:H22 (E22)} and injected with antibiotic, ceftazidime) 5ml for each rabbit, and treated with vitamin C (60mg/kg) (5 rabbits). Rabbits were treated daily pre- experiment with an oral dose of vitamin C(60mg/kg)for ten days. The percentages of bacterial isolation of E22 from fecal samples of rabbits after inoculated with {E. coli O103:K-:H22 (E22)}reference strain in four groups were (20,80,20 and 40%) in second, third, fourth and fifth group receptively. These results indicated that Vitamin C did not affect EPEC (REPEC) strain ''E22''. Whereas the pathological changes  after inoculation with E. coliO103:K-:H22 (E22) reference strain in rabbit model were hyperplasia of ileal payer's patches, in some animal intestinal epithelial ulceration was found with lymphocytic infiltration. Liver showed hydropic degeneration, area of necrosis with hemorrhages and few lymphocytic infiltration. Vitamin C did not affect EPEC (REPEC) strain ''E22'' (O103:K-:H2,  colonization and did not give significant protection against EPEC-induced changes and diarrhea. Although it had no effect on the EPEC-related increase of enterocyte apoptosis, it clearly contributed to an acceleration of epithelial cell proliferation in the ileal crypts. We showed that Vitamin C ameliorated somewhat the effects of EPEC on intestinal mucosal architecture. Showing hyperplasia of jejunal villi, payer's patches, ileum and mucous gland .There are also leucocytic infiltration in lamina propria..

The presence of an accessory or a duplicated mouth and mandible is extremely rare. The authors reported a case of a 19-year-old female patient with a duplicated oral cavity and mandibular dentition, presented to Khartoum Teaching Dental Hospital, Sudan. The clinical and radiological findings were described together with the surgical technique. To the best of our knowledge, this is the second adult case with an isolated duplicated oral cavity and mandible in the medical literature, but the first one fully illustrated with clinical images and radiographs.


The work of the contemporary British sociologist Anthony Giddens, and in particular his structuration theory, has been widely cited by Information Systems researchers. This paper presents a critical review of the work of Giddens and its application in the Information Systems field. Following a brief overview of Giddens's work as a whole, some key aspects of structuration theory are described, and their implications for Information Systems research discussed. 225 Information Systems articles, published in leading journals and conferences between 1986 and 2002 that have used Giddens's work are identified and coded into 11 categories. The papers in each of these categories are then analysed in the light of the preceding description of Giddens's work and the structure of structurational research in the Information Systems field assessed. Conclusions are drawn on the ways that Giddens's ideas have been used in Information Systems research.
