Several high standard studies analyzing the effects of knowledge flow of organizations have appeared since the fact that the creation of applicable novel knowledge is fundamental to economic growth was acknowledged (ROMER, 1986). According to PORTER (2000) the regional alliance of small and medium-sized enterprises as well as supporting institutions could provide these businesses such competitive advantages that enable them to keep up with multinational companies, even in a globalised market environment. Accredited clusters, subsidized by the EU, are specific kind of alliance formations, which facilitate competence and innovation. At present (February 2010), there are 18 accredited clusters operating in Hungary – a dozen and a half company associations which met the economic and cooperative criteria defined by the EU and thus reached all the important stages of accreditation in the process of cluster development. These clusters are the subject of the present study and analysis. The first part of this paper introduces different theoretical approaches to the cluster phenomenon, including the observation and analysis of intra-cluster knowledge flow characteristics. The main purpose of the present study is to describe and assess the actual cluster formation process of accredited Hungarian clusters in order to compare them to each other and to measure them in terms of efficacy. The contrastive analysis is based on quantifiable public data and interviews carried out with cluster management leaders. We also describe the theoretical framework of an alternative methodology for monitoring cluster knowledge processes and measuring cluster performance. Knowledge transfer between cluster members is essential for innovations. The new methodology reviews and induces the measurement of emerging knowledge processes in Knowledge Flow in the World of Cooperation: a Study on the Efficacy of Accredited Clusters in Hungary 1 order to assess intra-cluster knowledge flow sector-specifically. This novel, applied methodology differs from conventional analytical practices on several points and makes use of innovative solutions in order to be more in line with the aims stated above, i.e. to capture "volatile" knowledge flow in the innovation-oriented clusters.

Keith R. Briffa, 64, died on October 29, 2017. Keith was born December 27, 1952, in Liverpool, United Kingdom. He earned a B.Sc. (Honours) degree in Biological Sciences at the University of East Anglia (UEA) in 1974 and joined the Climatic Research Unit (CRU) there in 1977. He received his Ph.D. from the UEA School of Environmental Sciences in 1984, successfully defending his thesis "Tree-Climate Relationships and Dendroclimatological Reconstruction in the British Isles." He stayed at CRU for the 40 years of his remarkably productive and significant scientific career, having the title of Emeritus Professor at the time of his passing. Keith showed great breadth of scientific understanding, creativity, rigor, willingness and ability to collaborate and unflinching intellectual honesty. These attributes are clearly evident in all his work, from his Ph.D. dissertation to the most recent of his more than 130 publications. He has been a central figure in the elaboration and testing of new and improved approaches to dendrochronology in general and to dendroclimatology in particular. Especially indispensable contributions include methods for evaluating common signal strength in tree-ring collections, including Expressed Population Signal (EPS) and Subsample Signal Strength (SSS). Keith also investigated methods of tree-ring standardization based onGaussian filters, and later the groundbreaking Regional Curve Standardization (RCS) method.His identification of apparent reduced sensitivity of tree-ring records to temperature at high latitudes in recent decades ("divergence") stimulated much critical examination and improvement in dendroclimatology. Keith's research contributed greatly to the analysis of tree-ring networks on regional to global scales and their use in the rigorously tested reconstruction of climate fields based on the method of 'Orthogonal Spatial Regression' (OSR) developed in his thesis. He was at the very


Statistical sampling can play an essential double role in defining document sets in response to legal discovery requests for production. Retrospectively, looking backward at existing results, statistical sampling provides a way to measure quantitatively the quality of a proposed production set. Prospectively, looking forward, statistical sampling (properly interpreted) shows how the quality of a proposed production set can be improved. The proposed improvements depend on transparency of classification: in order to correct clashes between human judgments of sampled data and a proposed hypothesis, one must know the source of the misclassification. And in correcting such misclassifications, one must take care to avoid standard dangers like overfitting. Section 1 below sets the stage by presenting the most basic material on statistical sampling and introducing the concept of data profiles. Section 2 argues that statistical sampling in retrospective mode is the only practical way to assess production quality. Section 3 offers several reasons why statistical sampling assessment has failed to become the standard practice it deserves to be in the field of legal discovery. Section 4 focuses on the use of statistical sampling in prospective, forwardlooking mode, to drive iterative improvement. Section 5 describes at a high level some of our practical experience at Cataphora using iterative statistical sampling to force rapid convergence of an evolving responsiveness hypothesis with very high quality standards of review assessment. (In fact, the intrinsic role that statistical sampling plays in this process described in this section—a process that has consistently yielded measurably high quality—is one reason to consider the issues that arise in the preceding sections.) Along the way, we offer a variety of questions for discussion in a series of footnotes.


M e d i c a l centers. with increasine frequency, are employing their own in-house attorneys. The express purpose for this is to avoid the cost of large corporate law firms, as well as to secure greater control over costs connected with medical malpractice litigation, such as loss control, risk management, and self-insurance programs. But are these offices appropriately and competently providing the full spectrum of legal services to the medical centers they serve? This past spring, a conference in Chicago explored the role of in-house counsel in controlling corporate legal costs. The general consensus was that corporate clients, who consume from 65 to 85 percent of the legal services in the country, have allowed themselves to be "cowed by the demands of prestigious outside counsel." According to press reports, ineffectual in-house counsel were criticized for their inability to curb excessive corporate legal fees and expenditures. The legal fees of outside firms were characterized as just plain unnecessary."' Are inhouse lawyers in medical centers any more effectual in controlling the fees of their outside counsel?


Predictive modeling or predict analysis is the process of trying to predict the outcome from data using machine learning models. The quality of the output predominantly depends on the quality of the data that is provided to the model. The process of selecting the best choice of input to a machine learning model depends on a variety of criteria and is referred to as feature engineering. The work is conducted to classify the breast cancer patients into either the recurrence or non-recurrence category. A categorical breast cancer dataset is used in this work from which the best set of features is selected to make accurate predictions. Two feature selection techniques, namely the chi-squared technique and the mutual information technique, have been used. The selected features were then used by the logistic regression model to make the final prediction. It was identified that the mutual information technique proved to be more efficient and produced higher accuracy in the predictions.


J. M. Weed: The two papers on transformer losses are in a sense complementary to each other, but after both papers are read, there are some discrepancies apparent which need to be harmonized, and some points which still need to be brought out to clear up the subject.


The cylindrical turning model of Minimum Quantity Lubrication(MQL)was established based on FLUENT software.And the MQL spray process was simulated.Then the distribution characteristics of pressure and static pressure of the fluid on the flank were analyzed.And the MQL spray pattern was also analyzed.The results show:the strong pressure and high velocity of compressed air may influence the flow field of the wedge-shaped area;the flow characteristics of the wedge-shaped area have a great impact on the movement and penetration of MQL cutting fluid droplets;the negative pressure gradient of the wedge promotes the movement of cutting fluid spray;the cutting fluid droplet sizes vary from 1μm to 20 μm,and distribute according to certain rules.There are some reference value for the study of MQL cutting parameters and droplets recovery devices.


The effects of different drying methods on desiccation tolerance and longevity in seeds of foxglove (Digitalis purpurea L.) were assessed from just prior to mass maturity (when seeds have attained maximum dry weight), and at intervals during the post-abscission phase of development. Tolerance of drying under seed conservation conditions (15% relative humidity, RH, and 15 °C), was acquired close to mass maturity at 36 d after flowering (DAF). Increases in desiccation tolerance were induced when drying was delayed for 4 d by placing seeds in a near-saturated atmosphere (approx. 100% RH), or if seeds were pre-dried for 7 d at either approx. 32% or approx. 73% RH.

Irrespective of the drying treatment, seed longevity increased throughout the sampling period, i.e. beyond the point of mass maturity and throughout the post-abscission phase, up to the point of incipient natural dispersal. At each developmental stage, delayed drying or pre-drying led to an increase in seed longevity under controlled ageing conditions compared with seeds dried directly under seed conservation conditions. Increases in longevity were apparent as increases in the estimates for the intercept of transformed seed survival curves (Ki) and for the standard deviation of the normal distribution of seed lifespans, and also in the mean time to death of individuals in storage, consistent with a continuation of ripening events.

The results are discussed in relation to the assessment of seed longevity and to current post-harvest drying practices for seeds intended for long-term ex-situ conservation.


This research presents an assessment of the feasibility of Tasmanian stonefruit growers adopting electronic commerce. In order to achieve this aim a number of qualitative techniques were employed under an action research methodology. Although not all applications of electronic commerce are suitable within the environment under study, it is suggested that there are ways in which electronic commerce could provide value. However, inhibitors, some common to Small to Medium Sized Enterprises (SMEs), do exist. There is a need for these issues to be understood prior to adopting electronic commerce.


Davison, E.M., McGurk, L.M., Bougher, N.L., Syme, K. & Watkin, E.L.J. Amanita lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes. Nuytsia 23: 589–606 (2013). Three species of Amanita Pers. are documented from Western Australia. Amanita lesueurii E.M.Davison is described from the mid-west region. It is distinguished by its small to medium fruiting bodies with a white pileus and white universal veil (both of which become vinaceous-buff or grey with age), white gills, short white stipe with a small obconic or turbinate bulb, white partial veil, amyloid, elongate to cylindrical spores, and no clamp connections. Amanita wadjukiorum E.M.Davison is described from the Perth metropolitan area. It has medium to large fruiting bodies with a cream pileus that ages milky coffee to snuff brown, a pale grey or buff universal veil that ages hazel to drab, cream gills, grey to buff stipe with a napiform or fusiform bulb, white to cream to vinaceous-buff partial veil that disappears with age, amyloid, ellipsoid to elongate spores and no clamp connections. Amanita fibrillopes O.K.Mill., which was previously only known from the type locality, is a widespread but misidentified species. It has small to large fruiting bodies with a pale peach to pale salmon pileus that rapidly ages cream, a white universal veil that rapidly ages buff or milky coffee, white gills that age buff, white or pale pink stipe with a spherical or obconic or tapered bulb, white or buff apical partial veil that disappears with age, inamyloid, ellipsoid to elongate spores and no clamp connections. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank. Introduction The genus Amanita Pers. (Agaricales: Amanitaceae) is a large, cosmopolitan and conspicuous part of the fungal flora of many areas. The majority of species are difficult to identify using macroscopic features alone, and microscopic characters such as spore amyloidy, presence of clamp connections, and the microanatomy of the subhymenium and universal veil are very important for identification and constructing diagnostic keys (Bas 1969; Reid 1980; Tulloss 1994; Wood 1997). The genus is divided into two subgenera: subg. Amanita sensu Corner & Bas emend. Bas and subg. Lepidella (E.-J.Gilbert) Veselý emend. Corner & Bas, that are separated by the amyloid reaction of the spores. 590 Nuytsia Vol. 23 (2013) Many species of Amanita occur in Western Australia (Gentilli 1953; Bas 1969; Reid 1980; Miller 1991, 1992). Of these, some have probably not been discovered and several are yet to be formally named. In this paper we describe two new species from Western Australia, one from the mid-west region and another from the Perth metropolitan area. Some named species are difficult to identify with certainty because they were described from a small number of collections or localities, so that the range of variation within each species has not been established. Amanita fibrillopes O.K.Mill. (MycoBank number MB 358174), for example, was described from a single collection (Miller 1991), however it appears to be a widespread but misidentified species. Its protologue describes a small species with inamyloid spores and an aerolate pileus covered with dense, pointed brown warts. Whilst reviewing the Miller types, one of us (EMD) was struck by similarities between A. fibrillopes and a common and widespread species Amanita sp. 'persicina' ined. (Bougher 2009), concluding that they were the same. They have similar microanatomy and are similar macroscopically apart from the protologue's apparent incomplete description of the colours of the pileus and universal veil. Amanita sp. 'persicina' has a pale peach or salmon pileus when young, but the colour fades rapidly to buff, and the universal veil darkens with age from white to buff to brown. It appears that the type described by Miller (1991) was a collection of small, old Amanita sp. 'persicina'. In this paper we provide an expanded description of A. fibrillopes based on a larger number of collections than those studied by Miller (1991). DNA barcodes have become an important identification tool for all organisms. The nuclear ribosomal internal transcribed spacer (ITS) region has been proposed for adoption as the primary fungal barcode marker (Schoch et al. 2012). It has been widely used by mycologists and more than 172,000 fungal ITS sequences are deposited in GenBank. We provide new ITS sequence data for the two new taxa and for A. fibrillopes. Other gene regions provide more resolution in some fungal lineages. The most recent molecular phylogeny of Amanita uses the nuclear and mitochondrial large and small subunits of rRNA gene regions (Wolfe et al. 2012). These regions will provide additional information on relationships in future studies.


In this paper we evaluate the comparative performances of FDL buffers with VDL and without it. By introducing VDL, the gap between packets in FDL buffers can be reduced and throughput can be enhanced.

Multiobjective memetic optimization algorithms MMOAs are recently applied to solve nonlinear optimization problems with conflicting objectives. An important issue in an MMOA is how to identify the relative best solutions to guide its adaptive processes. In this paper, the authors introduce a framework of adaptive multiobjective memetic optimization algorithms AMMOA with an information theoretic criterion for guiding the adaptive selection, clustering, local learning processes, and a robust stopping criterion of AMMOA. The implementation of AMMOA is applied to several benchmark test problems with remarkable results. The paper also presents the application of AMMOA in designing an optimal image watermarking to maximize the quality of the watermarked images and the robustness of the watermark.


Abstract Xanthan gum is a biopolymer used in several different industries for a variety of applications. In the Petroleum Industry, xanthan gum has been applied in Enhanced Oil Recovery (EOR) methods for mobility control due to its Non-Newtonian rheological behavior, relative insensitivity to salinity and temperature compared to other conventional synthetic polymers, as well as its environmentally-friendly characteristics. As challenging reservoir conditions arise, candidate polymers should meet the screening factors for high salinity, high temperatures and heterogeneous reservoirs. This paper aims to evaluate the effects of temperature and monovalent salts on the rheological behavior of xanthan gum for Enhanced Oil Recovery purposes. We tested polymer solutions with brine salinities of 20,000/110,000/220,000 ppm of Sodium Chloride in a rheometer at temperatures of 23, 50, and 77°C. The results acquired showed that temperature plays a key role in viscosity and salinity protected the solution viscosity against negative thermal effects, unusually a turning point is observed where the increase in the monovalent salt content enhanced the polymeric solution viscosity. Such investigations coupled with a detailed discussion presented in the paper contribute to understand critical aspects of xanthan gum and its capability to provide basic requirements that fit desired screening factors for EOR.

R is a widely used software and computing environment for statistics, which provides a variety of statistical techniques and packages (R Core Team, 2018). Many R packages provide interfaces to other computer languages to bring new functionalities to R or to accelerate computations, such as Rcpp (Eddelbuettel & François, 2011) and V8 (Ooms, 2019). The package JuliaCall provides an R interface to Julia, which is a computer language for high-performance scientific computing (Bezanson, Edelman, Karpinski, & Shah, 2017). JuliaCall embeds Julia in R, and provides functions to evaluate Julia commands, to call Julia functions, to transmit data objects between R and Julia, and so on. It also provides many utilities for user convenience. For example, JuliaCall gives detailed error messages for the embedded Julia. It also provides Julia package management functions such as installation and loading, and utility functions to get the documentation of Julia functions. JuliaCall can also be used in R Markdown document as the engine of Julia language, see Section 2.77 in Xie, Allaire, & Grolemund (2018).


Based on the field quantization, the angular distribution of the ionization rate of hydrogen atoms with the effect of a finite number of photons is computed in this letter. We find that the angular distribution of the ionization rate will fluctuate with the initial photon number of the field, and have a peak value higher than that predicted by Keldysh-Faisal-Reiss theory. This ionization peak is the embodiment of quantum effect. Furthermore, our calculations show that the phenomenon of ionization peak also exists when the initial field state is a coherent state.


In the molecule of the title compound, C15H13N3O3, an intramolecular O—H⋯N hydrogen bond influences the planarity of the conformation; the dihedral angle between the benzene rings is 11.4 (3)°. In the crystal, molecules are linked by N—H⋯O hydrogen bonds into chains in [101].


This paper describes how models of slender MEMS components can be generated using symbolic simulations based on Cosserat theory. Due to the generality of the method, models can be generated for a wide range of components under different stress conditions. The structure of the Cosserat- based models is presented, showing their concise, mathematically accurate representation. This potentially results in faster simulation results than finite element analysis, requiring detailed 3d meshed models. The use of Cosserat models in symbolic simulations enables generation of closed-form expressions for the dynamics of components with complex shapes. The influence of various stress conditions, such as package-induced and residual stress, on the behavior of the component can be included in these expressions.


Induction: Breast cancer is a malignant neoplasm that grows in a disordered and uncontrolled way reaching the breast tissue and its peripheries and one of its methods of treatment is the mastectomy that it is a surgical procedure in order to spread the affected tissue. As a result of the surgical procedure, some postural changes occur due to the acquired analgesic posture, and joint limitations also occur due to the surgical incision and its complications. This study will be compared to the effectiveness of the Isostretching® method and hydrokinesiotherapy for joint amplitude gain and postural correction. Methods and Materials: A study of the experimental type performed at the Clinic School of Physical Therapy at Unisul, Tubarao - SC. It was performed in 10 sessions consisting of the evaluation, which analyzes the joint amplitude of the shoulder in the abduction and flexion movements and the postural evaluation of the trunk and upper limbs; after applying the two therapeutic methods in two distinct groups (8 sessions); and reevaluation. Results: The estimated sample number (n = 30) was not achieved. A total sample of 6 volunteers divided into 2 groups (n = 3) each was obtained. In the comparison there was no statistically significant increase of articular amplitudes and postural alignments (p <0.05) in the physiotherapeutic treatments compared. Final Remarks:
In the present study, the two methods demonstrated similar effects, however, the result was not significant (p <0.05) because the number of volunteers estimated for the study was not reached. It is suggested that further studies be performed.

Prostate cancer (PCa) is one of the most frequent malignant tumors in men worldwide. The primary treatment of localized disease consists of radical prostatectomy and radiation therapy. Unfortunately, tumor recurrence after initial treatment is not uncommon and is suspected by the rise in prostate-specific antigen (PSA) levels. Distinguishing between a local recurrence and distant metastases is critical to define an effective therapy (1). The most common pattern of tumor spread involves abdominopelvic lymph nodes and the bones followed by the lung, liver, pleura, supradiaphragmatic lymph nodes and adrenal glands. Rarer metastatic sites may be observed in nearly any organ such as the brain, breast, diaphragm, gastrointestinal tract, skin, heart, penis and testicle (2-5). Traditionally, PCa recurrence is investigated by prostate imaging such as computed tomography, magnetic resonance and bone scintigraphy. However, this approach has limited sensitivity particularly at low PSA levels (1). The recently introduced positron emission tomography/computed tomography (PET/CT) with the new tracer 68Ga-labeled prostate specific membrane antigen ligand (PSMA) has revolutionized the evaluation of patients with PCa recurrence. PSMA is a transmembrane enzyme which is significantly overexpressed in the majority of Atypical metastases from prostate cancer detected on 68Ga-PSMA PET/CT: a case series _______________________________________________

This paper presents a computational economics model of the property-liability insurance underwriting cycle. This computer experiment is built on downward-sloping demand, a simplistic version of the capacity constraint model of insurance supply, and a simple pricing rule. The pricing rule has each experimental insurer determine its price from the expected losses per-policy (a constant), the previous year's policyholders' surplus and the previous year's number of customers. Through the use of directional bit sequences a common structure is revealed between the simulated aggregate underwriting margin and the actual aggregate underwriting margin, 1930–2000. The common structure between these aggregate variables is evidence the property-liability underwriting cycle, in a consistent effort to reach equilibrium, follows an algorithmic process. Of more general inference; the pursuit of equilibrium, as an attractor, is the only consistent characteristic of the algorithmically generated process. This algorithmic process precludes the notion of a consistent continuous probability distribution being the basis of a data generating process (DGP). The times series behavior of the simulated underwriting margin, as it fluctuates around the equilibrium attractor, can assume a variety of shapes across many realizations of the algorithmic process. Finally, behavior of the simulated individual companies is not, for the most part, correlated with the aggregate behavior, and virtually all individual transactions are out-of-equilibrium transactions in the sense that they occur along the demand curve.


After the application of terminal management system in Medical Library of Chinese PLA was introduced,the problems found in its application were analyzed with certain suggestions proposed for their solution.


EXAMINATION of the heart is ain essential part of a genieral examination in the horse, whether before sale or for insurance. It should always be carried out before the admiiinistration of an anaesthetic or tranquillisinig agent. Even well tried drugs may, on rare occasions, produce fatal side effects. In these circumstances, if a heart examination was not carried out before the drug was administered, a charge of negligenice might be levied againist the veterinarian. Most heart conditions can either be detected oI suspected from a simple stethoscope examinationi. Whether one exaimines horses regularly or occasionally, it is prudenit to carry out the examiliniation systematically. This wax obvious conditions or signs will not be missed. A comprehensive history should be obtained. The physical examination should include a general inspection of the animal followed by palpation of the arterial pulse, chest wall anld sternum. Then auscultate the heart.


Globally,fisheries production is facing concerns in the form of sustainability issues, increased fuel consumption and resultant burdens contribute to worsen the scenario. All specified concerns are most prominent in trawling industry which is the most common and dominating worldwide. As India is dependent deeply on fisheries for employment and food security, the energy cost is a concern among seafood consumers, seafood traders and fishing communities. Rate of average fuel consumption of mechanised trawl fishing fleet of Kerala in a year is estimated. Rate of fuel consumption found to be higher in very large trawlers and lower in small trawlers. While comparing single-day trawlers found to be consuming 57% lesser fuel than multiday trawlers. If small trawlers are taken as a base, the rate of fuel consumption is 18.5% higher in medium trawlers, 74% higher in large trawlers and 180% higher in very large trawlers. The average annual fuel consumption of is highest in very large trawlers followed by large trawlers, medium trawlers, small trawlers (multi-day) and small trawlers (single-day).

BS 225 impact on the exterior features of the Acipenseridae has been studied. BS 225 is a microbiological preparation containing Bacilus Siamensisas as a basis. The efficiency of its application in sturgeon aquaculture is demonstrated by a scientific and commercial experiment. Each test group of sturgeon underyearlings had its own feeding schedule at a definite dosage. It was proved experimentally that the dosage determines exterior features and essential biological parameters, such as Fulton's condition factor, fineness ratio, scale factor, thickness ratio and mass buildup. The obtained data confirm that microbiological preparation initiates sturgeon growth, is beneficial for fish exterior features and improves winter resistance, environmental resistance and survivability of fish.


The present study attempts to explain the problem encountered by Baker and Collier (1968) of a "humping" of empirical size of F t under permutation for the simple randomized block design for combined levels of variance heterogeneity and block-treatment interaction. Values of comcted nominal size were calculated with the degrees of freedom corrected by two methods: one to correct for variance heterogeneity alone and another to correct for the change in variance heterogeneity induced by the block-treatment interaction. The second method yielded nominal values of size which showed the best agreement with empirical values of size having the "humping" but did not exactly duplicate the peculiar pattern.

The aim of this study was to determine the potential ability of biostimulant-mixtures to recover the herbage and essential oil yield, as well improve the essential oil quality, of simulated hail-damaged rose geranium ( Pelargonium graveolens L'Her.). The experiment was carried out in a 3 × 4 factorial treatment design and laid out in a randomised complete block design in a temperature-controlled greenhouse during 2019 season. Treatments consisted of three hail damage simulation levels and three biostimulant-mixtures and a control. Plants grew taller when biostimulant-mixtures were applied from levels 2 up to 3. Level 3 treatment increased the essential oil yield of plants which sustained up to 50% foliage loss, and intact plants. Citronellol and geraniol content, as well the citronellol to geraniol ratio improved with the level 2 treatment in plants that sustained 100% foliage loss. It can be concluded that the application of biostimulants-mixture should be applied from level 3 concentration to improve the herbage yield and the essential oil quality of rose geranium plants with more than 50% foliage loss. Plants with less than 50% foliage loss can be treated with a biostimulant-mixture from level 2 to improve essential oil yield and the densities of brevicollate trichomes.

Maximizing network throughput via back-pressure routing is the subject of a considerable body of literature. However, the associated optimal throughput guarantees come at the cost of excessively high delays. Though there exists some proposals in literature for improving the delay performance, the impact of these proposals on the delay performance is very little in loopy networks (i.e., networks with routing loops). In this demonstration, with series of experiments over different topologies, we show that the basic back-pressure algorithm and two of its variants for improving delay performance induce extensive routing loops with associated high packet delay even in simple network topologies.


We argue that the C-element que, following fronted wh-elements and fronted focused elements more generally in Brazilian Portuguese, is realized as Fin, rather than Foc (MENDES KANDYBOWICZ, 2021; pace MIOTO, 2001; MIOTO KATO, 2005). We put together three observations from the literature: (i) the appearance of que is contingent on wh/focus fronting; (ii) que introduces a finite clause, and (iii) que disappears under sluicing. We present novel evidence that Nupe's focus particle is a left-periphery element and that Nupe provides a concrete counterexample to Merchant's (2001) sluicing-COMP generalization. A comparison between Nupe and Brazilian Portuguese regarding the presence of nonoperator material in sluicing constructions is crucial to establishing sluicing as FinP ellipsis (BALTIN, 2010; ABOH, 2010), instead of TP ellipsis, as standardly assumed, as well as que as a Fin element. We offer an analysis that captures all of the Brazilian Portuguese distributional facts, according to which que is a Fin head with a [finite] feature and an uninterpretable [ufoc] feature that must be licensed by Agree with a higher focus head.


A new thermal neutron detector with the domestically produced THGEM (THick Gas Electron Multiplier) was developed as an alternative to 3He to meet the needs of the next generation of neutron facilities. One type of Au-coated THGEM was designed specifically for the neutron detection. A detector prototype had been developed and the preliminary experimental tests were presented, including the performance of the Au-coated THGEM working in the Ar/CO2 gas mixtures and the neutron imaging test with 252CF source, which would provide the reference of experimental data for the research in future.


The work was developed in the farm "Las Papas", belonging to the National Institute of Agricultural Sciences (INCA); located at the 230 00' north latitude and 820 12' west longitude, to a height of 138 m above sea level in San Jose de las Lajas, Mayabeque. With the objective of evaluating the responses elicited in performance, product variations of temperatures during the crop cycle, the Roman variety plantations were made during the years 2014 and 2015, respectively. The behavior of the minimum temperatures, average and maximum and the amplitude of these was assessed. The total and commercial yield in t ha-1 and the composition of the tuber size was estimated. Statistical processing was performed with the use of Statgraphycs v5.1 program and graphics were performed using the Sigma Plot v3.1 program.


We ponder about the kind of problems and perspectives of a "formalized epistemology", by considering the advantages than one can get from a concern with the "formal", with its structural orientation, that would favour comprehensive, unifying and synthetic, intelligibility. We confront this perspective with that of the changes in knowledge, considering the relation between form and meaning for knowledge contents, and examine the notion of "epistemic operation" as instrumental for creating new forms, at the theoretical and meta-theoretical levels. Actually, the notions of form, of formal and of object are not independent of the problem of a subject that decides on conventions and choices. "Epistemic operations" might suggest a link with "algorithmic functions" for knowledge statements, that themselves entail the risk of reductionism in a naturalistic conception of representation.


ABSTRACT A new method of rapid driving of a liquid crystal lens is proposed. High external voltages are initially applied to the liquid crystal cell accompanied with an in-plane electric field. The occurring of disclination lines is prevented and the response of the lens becomes more than two times faster.


This article provides a theoretical approach for the category of speech and language disorders, underlining the common aspects, but also the differentiating ones. The two categories are also approched, in a more detailed, specific and practical manner, by taking into consideration the craniostenosis diagnose. Thus, the main question of the second part from this article is: Does craniostenosis leads to a speech or a luanguage disorder? Under what circumstances? The answer underlines the fact that craniostenosis can involve both speech and language disorders and that individual approach can be the only solution in order to correctly delimitate things in this case.


This study investigated differences in clinical symptoms and developmental functioning profiles as well as sex‐specific correlations of clinical characteristics and communication abilities, motor skills, and maladaptive behaviors in male and female preschoolers with autism spectrum disorder (ASD). Fifty‐two females (mean age 4.5 ± 2.16 years old) and 62 males (mean age 4.2 ± 1.17 years old) with ASD were enrolled and assessed by measures including the Autism Diagnostic Observation Schedule‐Second Edition (ADOS‐2) and Psychoeducational Profile‐Third Edition (PEP‐3). We found intellectual disability in 91.2% of the children. While preschoolers with ASD showed comparable severity of restricted and repetitive behaviors (P = 0.17), females with ASD were less severely affected than age and intelligence quotient‐matched males with ASD in the ADOS‐2 social affect domain (P value = 0.001) and calibrated severity scores (P = 0.002). Interestingly, sex‐specific linear regressions revealed that fine motor skills were predictive of impaired social affect in males but not in females. Specifically, motor skills might be the core feature for sex differences in ASD. Although preliminary, this finding suggests the need for more sex‐specific diagnostic and intervention strategies in order to improve early identification efforts and specific intervention targets.


The WHO/FAO have requested data on food consumption to better understand the increasing toxicological results of foodstuffs. The aim of this study was to determine the food consumption characteristics of the consumers living in smallscale mining areas. Commonly consumed food crops of each category: fruit, cereals, vegetables, legumes and root tubers were selected. In all, 308 consumers were sampled using a one-week dietary recall tool and a stratified sampling method of the consumers. The @Risk Microsoft add-in was used to analyze the data. The results show that the adolescents (1017 years) consumed cowpea (233.90 g/day) and cassava (666.96g/day) at a relatively higher level compared to children (3-9 years) and adults (18-64 years). Likewise, adults consumed yam (136.65g/day), maize (1739.37g/day), rice (1272.40g/day), pineapple (184.97g/day) and watermelon (656.55g/day) at a relatively higher level compared to children and adolescents. On the contrary, whereas children generally consumed lower quantities of food, they presented higher exposure frequency to cowpea (364 days/year), root tubers (36-364 days/year) and grains (286-364 days/year) compared to adults and adolescents. Both adolescent and adult population subgroups presented higher exposure frequency to vegetables (364 days/year) relative to children (104-364 days/year). The findings further show that, in increasing order rice and maize are the most consumed crops. The adult population subgroup, in the study area may be vulnerable to contaminants in maize grains than other dishes categories due to the high mass consumed and high exposure duration. Children may be vulnerable to contaminants in maize grains because of the high exposure frequency.


In recent years there has been increasing support from volunteers in providing vital public services. In Estonia some of the positions of the Rescue Service are manned by voluntary fi remen, the Police Forces are assisted by volunteers, and recently the Estonian Defence League has assumed responsibility for the territorial defence. The need to create a positive work environment for volunteers in order to achieve better job performance has increased the need to study the relationships between the volunteers and the organisations that they assist. In the last decade the concept of the psychological contract has become of interest to researchers. The psychological contract is defi ned as the belief in a reciprocal exchange agreement between a person and an organisation1. In the individual-organisation relationship, if the organisation's tenets coincide with a person's beliefs, then the psychological contract would precipitate a positive outcome, such as job satisfaction and superb job performance. The quality of the psychological contract, however, is determined by the organisational leadership and the organisation's human resource practices rather than by the workforce, as employers rather than employees are in the dominant and advantageous position by virtue of their capacity to design and develop the working conditions and employment relationships2. The psychological contract has also been called a silent contract because its content is individual and subjective; it is also often unacknowledged by the parties involved. A survey carried out among Estonian enterprises in 2013 indicated that the actual expectations of


Abstract. The article is devoted to the topical problem of clinical allergology — differential diagnosis of atopic dermatitis. The clinical manifestations of atopic dermatitis are quite similar to the extremely large number of different diseases and pathological conditions in children, which often leads to misdiagnosis. The complexity of the differential diagnosis of atopic dermatitis in children with a detailed description of different pediatrics diseases: from dermatological diseases (seborrheic dermatitis, eczema, shingles, scabies, ichthyosis, psoriasis, bullous epidermolysis, allergic dermatitis, cutaneous mastocytosis) to oncological (T-cell skin lymphoma), orphan metabolic diseases (hereditary disorders of tryptophan metabolism, phenylketonuria, Netherton's syndrome, etc.) and primary immunodeficiencies (Bruton's disease, Job's syndrome, Wiskott-Aldrich syndrome, selective IgA immunodeficiency etc.) are described. Сommon features of above mentioned diseases are listed, also, special attention is paid to variety of the pathognomonic symptoms.

The relationship between the duration of the complex QTc ECG and clinical signs of arterial hypertension (AH) in 54 patients (16 men and 38 women) 1-3 degree and I-III stage, mean age 58 ± 18 years, was investigated. 3 classes of QT interval duration were allocated: classified shortened ( 320 ms and 440 ms). The binomial distribution of frequencies of studied parameters in classes of the QTc interval for alternative criteria was determined. The duration of the QTc interval in the sampling was 350 ms – 490 ms. The proportion of the normal range (> 320 ms and 440 ms) – 0.15. The probability of occurrence of QTc prolongation ECG increased in elderly patients, obesity, abusing of alcohol, mild and moderate degree and stage II AH, diabetes mellitus, atherosclerotic cardiosclerosis, stable angina functional class (FC) II, HF FC III and II A stage. Dependencies of the elongated QTc of ECG from the sex of the patients have not been established.


【Objective】The purpose of the study was to discuss the factors affecting the subclinical mastitis.【Method】 5 080 milking cows from five large scale dairy farms were investigated during the period from Jan,2009 to Jan,2010.The case control study was focused on the age,parity,daily milking yield and compartments of udder and 50 mastitis samples were randomly selected to process the etiological examination.【Result】The results showed that 8.5% of the research population were clinical mastitis positive,while 45% of that were subclinical mastitis-positive.Further,the incidence of suffering from mastitis in Chinese Holsteins may have enhanced with the increasing of the age,parity,daily milking yield.Besides,the incidence of subclinical mastitis in left and back compartment of the udder were higher than that of right and front compartment of the udder,respectively.The main pathogens were Staphyloccocus Aureus for subclinical mastitis.【Conclusion】The main means to decrease the subclinical mastitis was to strengthen the routine health management.


This study determined the concentrations of heavy metals in the water and two freshwater fis hes ( Chrysichthys nigrodigitatus and Parachanna obscura ) from Ibiekuma Stream in Ekpoma, Nigeria. The metals distribution in the tissues of the fishes was also examined. Collection of samples was carried out at three selected Sample Stations alon g the stretch of the stream, while sample treatment and analyses were according to standard methods. The results showed that metals (Cd, Cr, Fe, Cu, Mn, Ni, Pb, V and Zn) mean levels in water were differe nt along the stretch of the stream, but were genera lly lower than the toxicological threshold limits recommended for the various metals in drinking water. However, in fish/ fish tissues, the results showed that the levels of Fe, Cr and Mn exceeded th e recommended maximum limits in food fish. Consequently, the water of the stream could be considered suitable for drinking an d other domestic uses, but the fishes of the stream , based on the elevated levels of Fe, Cr and Mn could not be recommended for consumption. Close monitoring of pollution stress especially of heavy metals in the stream is strongly recommended in ord er to avert possible metal induced health hazards f rom the consumption of the fishes of the stream.


To synthesize and identify the hapten and complete antigens of melamine for the purpose of preparation of anti-melamine antibodies,2-chloro-4,6-diamino-1,3,5-triazine were reacted with 3-mercaptopropionic acid to produce hapten(3-(4,6-diamino-1,6-dihydro-1,3,5-triazin-2-ylthio)propanoic acid). The molecular structure of the hapten was identified by mass spectrometry and infrared spectrometry. The hapten was respectively conjugated to carrier protein bovine serum albumin and egg ovalbumin to generate complete antigens by the active ester method and the conjugates were preliminarily identified by ultraviolet spectrum and further validated by animal immunization. The results indicated that the hapten and complete antigens were prepared successfully. Synthetic routes were feasible and the results laid the foundation for the following preparation of anti-melamine antibodies.

A phenomenological model is proposed for the transformation of interband conductivity caused by electron transitions through the optical (dielectric) gap ℏωg into the intraband conductivity of hole carriers in high-temperature superconductors under chemical doping. The interrelation between the interband and intraband conductivity components is analyzed in terms of the spectral function N(ω)∼∫σ(ω)dω for integral conductivity of the normal phase. Two groups of coexisting charge carries of the p- and d-types with different relations with interband transitions are singled out. The integral conductivity of narrow-band d-carriers is determined by interband excitations with the gap attenuation Γ∝ωg. The integral conductivity of wide-band p-carriers is not connected with interband excitations and is determined by the standard Drude spectrum. The obtained spectral functions are compared with the available data for La2−xSrxCuO4 and YBa2Cu3O6+x in the doping range from the beginning of metallization up to loss of s...


This case study highlights challenges such as financial strain and risk of domestic violence experienced by dementia caregivers. Using methods described by Yin (2003), two cases – a 76-year-old woman (Ada) who cared for her husband, and a 32-year old woman (Chika) who cared for her father were selected from a larger study on dementia caregiving in Anambra state. Data, including interview transcripts and field notes, were analyzed for themes. For both women, extreme financial hardship further complicated dementia caregiving challenges. For Chika, there was also the issue of physical assault by her husband who accused her of neglecting her duties at home to care for her father. Despite this, she continued caregiving at the risk of more retribution. The implications of the findings are discussed.


Leadership theories are a relatively recent phenomena that have been advanced by the sudden interest in historical leaders and the desire to identify the characteristics and behaviors that these leaders exhibited. By understanding the characteristics of the leader, their successes and failures, as well as the political and work environment they faced, the modern day worker can hope to replicate this success.


Purpose

The purpose of this paper is to investigate the large case of enterprise resource planning (ERP) system implementation in Latin America, performed between 2011 and 2015 in a Brazilian, multinational, publicly traded company. Using the organizational change literature as background, this research analyzes the barriers and factors of success by comparing the perspectives of ERP implementers and end-users, identifying success factors and barriers of this project. A conceptual framework is developed.

Design/methodology/approach

The case study method was used to conduct an in-depth analysis of the interviews that captured the complexity of this process. The change management project team had exactly 11 implementers, of whom ten were interviewed, and 45 end-users, of whom 20 were interviewed.

Findings

The results suggest that end-users and implementers have opposite perceptions regarding the role of previous experience, organizational processes, capacity for change, leadership behavior, and the interaction of business units. In general, implementers presented a more critical perception of the change processes. Conversely, implementers and end-users agreed that business needs and cultural values facilitated the ERP implementation, whereas organizational structure and geographic dispersion constrain it.

Research limitations/implications

This research could have analyzed the results by region or by production line.

Originality/value

The major contribution of this research is to offer a conceptual framework to analyze different views about the same project. This study deepens the understanding of ERP implementations by adding studies from other countries and different cultures. For practitioners, this case study aims to offer the experiences and perceptions that implementers and end-users had about the largest ERP implementation system in Latin America.


A standard assumption in mobile fading channel modelling is that the mobile station (MS) moves along a straight line with constant speed. In practice, this assumption is violated in most propagation scenarios. For the development of more realistic channel models, it is therefore important to relax this restriction by allowing the MS to change its velocity. In this paper, we study the effect of velocity changes on the statistical properties of multipath fading channels. Expressions will be derived for the local autocorrelation function (ACF), the Wigner-Ville spectrum, the average Doppler shift, and the Doppler spread. Our findings show that a variation of the speed and/or the direction of the MS results in a non-stationary channel model. The Wigner-Ville spectrum cannot be interpreted physically as a generalized Jakes (Clarke) power spectral density (PSD); although it includes the latter one for the special case that the MS moves with constant velocity.


SUMMARY A nonlinear time series predictor was proposed, in which a nonlinear sub-predictor (NSP) and a linear subpredictor (LSP) are combined in a cascade form.This model is called "hybrid predictor" here.The nonlinearity analysis method of the input time series was also proposed to estimate the network size.We have considered the nonlinear prediction problem as a pattern mapping one.A multi-layer neural network, which consists of sigmoidal hidden neurons and a single linear output neuron, has been employed as a nonlinear sub-predictor.Since the NSP includes nonlinear functions, it can predict the nonlinearity of the input time series.However, the prediction is not complete in some cases.Therefore, the NSP prediction error is further compensated for by employing a linear sub-predictor after the NSP.In this paper, the prediction mechanism and a role of the NSP and the LSP are theoretically and experimentally analyzed.The role of the NSP is to predict the nonlinear and some part of the linear property of the time series.The LSP works to predict the NSP prediction error.Furthermore, predictability of the hybrid predictor for noisy time series is investigated. The sigmoidal functions used in the NSP can suppress the noise effects by using their saturation regions.Computer simulations, using several kinds of nonlinear time series and other conventional predictor models, are demonstrated.The theoretical analysis of the predictor mechanism is confirmed through these simulations. Furthermore, predictability is improved by slightly expanding or shifting the input potential of the hidden neurons toward the saturation regions in the learning process.

the Neuro8pora or bacterial mutants. In addition, it seems improbable on structural grounds that these benzenoid compounds would be intermediates in the synthesis of such hydroaromatic compounds as prephenic acid. It is not known at present whether vanillic acid is formed by methylation of the 3-hydroxyl group of dehydroshikimic acid followed by dehydration, or by direct methylation of protocatechuic acid. Gross et al. (1956) have shown that vanillic acid is a potent inducer of protocatechuic acid oxidase in Neuro8pora, and therefore it is of added interest that this compound occurs naturally in Neuro8pora.


The economic performance of systematic economic analysis performed by industrial enterprises and research and production associations depends essentially on the quality of the source information. Expansion of the sphere of complex economic analysis and deepening of economic-analytical researches in the conditions of functionally developed constructions (systems) of strategic regulation (management) of special purpose by industrial enterprises and scientific-production associations can be ensured only on the basis of further improvement of planned, regulatory and accounting-economic information, as well as increasing the analyticity of primary information. The integrated fund (reserve) used in the systematic (comprehensive) economic analysis of planning, accounting, reporting and other information should contain indicators that objectively reflect not only those that occur in enterprises (associations) economic processes, but also that It is very important that they are built on a unified theoretical and methodological basis according to a consistent methodology. Fulfillment of the specified requirement will ensure achievement of necessary compatibility of these indicators at all investigated in the process of analysis of the levels of the management system and production stages. Organizational conditions for performing the most important functions of management (planning, accounting, control, analysis and regulation) also necessitate the differentiation of the general information fund into separate types in order to form different information sets, in particular, such as complex and local (thematic) information; constant and variable information; one-time and periodic information; information verbally, on "manual" documents and on machine carriers; information transmitted from supervisor to performers and backwards, and so on. Noting the urgent need for further improvement of information systems, companies and associations based on the needs of integrated economic analysis, please note that recorded in the project objectives integrated economic analysis should not break away from the existing organizational and technical capabilities, whether initial education (primary) data.

This study deals with the removal of Cu(II) using rice husk and its acid treated modified form as adsorbents under batch experiments. Different parameters have been investigated for the adsorption of copper metal. Equilibrium time for copper adsorption was found 90 minutes. Maximum percentage for removal of Cu(II) was found at pH=4 in both raw form of rice husk and its treated form. Percentage removal of copper metal was up to 90% for treated rice husk and up to 70% for raw form of rice husk. It could be concluded that the removal efficiency was enhanced by increasing wastewater initial concentration in the first percentage of adsorption and then decreased due to saturation of rice husk particles. Also according to achieved results, calculated saturation capacity in per gram rice husk for Cu(II) were 36.587 and 45.267 mg/g from raw rice husk and treated form of rice husk respectively. The amount of Cu(II) adsorbed increased with increase in their contact time. The rate of reaction was fast. So that 20–30 min after the start of the reaction, between 40 and 50 % of metal ions were removed. The pseudo second order kinetic model provided the best correlation of the used experimental data compared to the pseudo first model with a R2 of 0.984 and 0.979 for raw rice husk and treated form of rice husk respectively.


Railroad Valley is a graben block in the Basin and Range structural province. Topographically, it is basically flat with recent playa deposits on the surface. Two structural deeps exist in the valley. Five oil fields are associated with the northern deep. All oil fields are related to faulting. Oil has been generated from Tertiary Sheep Pass and Mississippian shales. This generation is probably due to recent local heating of the valley by intrusive rocks. Temperature gradients are as low as 0.9°F/100 ft (16°C/km) to as high as 7.3°F/100 ft (133°C/km). Eight million barrels of oil, with no significant quantity of gas, have been produced from the fields. The seals on the fields are imperfect and any gas generated, and much oil, has probably leaked into the overlying valley fill. Trap Spring and Eagle Springs fields are hydrostatically pressured whereas Bacon Flat, Currant, and Grant Canyon fields are overpressured. The concept of immature source rocks occurring near a valley with high heat flow may improve exploration success. End_of_Article - Last_Page 936------------


The reaction of Co(NO3)2 · 6H2O with a tripodal ligand leads to a new complex {[Co(L)] · 2NO3 · 8H2O} (1) confirmed by single-crystal X-ray diffraction, infrared spectroscopy, and elemental analysis. The particular interest of 1 is in the formation of a 1-D water tape consisting of (H2O)16 cluster units, the neighboring water tapes are connected by free nitrate anions via hydrogen bonds into a 2-D guest layer. These guest layers are alternately packed face-to-face with the 2-D host layers along the a-axis to form a 3-D supramolecular architecture. There exist C–H ··· N and C–H ··· O weak hydrogen bonds between the guest layer and host layer. These weak hydrogen bonds and water–nitrate, water–water hydrogen bonds are important for the stability of the overall structure.


The aim of the study was to examine travel writing over a significant period of time in order to understand more about the nature of travel writing in itself and to determine what changes may have taken place within the genre over time. A secondary aim was to carry out an exploration of the S E Asia Collection in the Library of the University of Hull.

In order to focus the study on a manageable body of work, the geographical area was narrowed to that of the island of Borneo and the texts to those of book-length.

The study began with a reading of a wide range of material which related to the subject of the thesis. From this essentially exploratory bibliographical research arose three things. Firstly, a body of material which could be reasonably defined as travel writing about Borneo was identified. Secondly, a broad categorization of sub-groups within that body of material began to emerge. Coincidentally, further ideas about the nature of travel writing, particularly in the context of the exploitation of East by the West, developed.

There followed a detailed and careful review of the texts which served to refine the characteristics of the sub-groups and show the ways in which changes in the genre had taken place over time.

The thesis concludes that while there have been significant changes in the nature of travel writing, there is an interesting degree of continuity, for example, curiosity as a motivating force and confidence as a characteristic., And where a writer writes from within the role of explorer, there is a remarkable number of characteristics which remain constant over time.

Throughout the period under study, different kinds of writer have become travellers, with varying motives, producing new kinds of travel writing: as the world has become smaller, the focus of the travel writer has become narrower and the ethos more personal.


The object of radiographs preceding stereotaxic operations is to furnish exact data showing the position of certain intracerebral reference points (e.g. anterior and posterior commissures) in relation to the surface of the brain, to the zero position of the electrode, etc. This information can be obtained only if the size and shape of the parts of the skull and brain under study are exactly reproduced, in other words, if the distortion produced by the divergent X rays originating in the focal spot of the X-ray tube is avoided or corrected, so that instead of the ordinary standard roentgenogram an orthoroentgenogram is obtained. For this purpose various methods have been tried. Talairach (1954) used a distance of 4·25 metres between the focal point of the X-ray tube and the film (teleradiography) in order to obtain "parallel" X rays. This method necessitates a relatively intense and long irradiation and is therefore somewhat inconvenient and potentially dangerous; it is also difficult to obtain satisfactor...


A nursing home has three discharge cracks, determined at admission and reviewed periodically along with treatment plans. Advised by the admitting physicians, the nursing home social worker assesses each resident's discharge prognosis: (1) a discharge plan is in effect; (2) discharge is problematic; or (3) no discharge is planned. A substantial amount of the literature in the field portrays the nursing home experience as iatrogenic. A study was undertaken to determine the extent to which one nursing home's residents who were admitted with plans for discharge did not return home and to examine the resons for those patients' derailment. A 160-bed Rhode Island nursing home's case records for 1978-84 were examined. The results revealed that, of 419 residents, 79 were expected to return to the community. Only 13 of those 79 did not return home. Content analysis of those 13 residents' histories showed that two chose to remain in the nursing home, four had families who declined to fill caregiver roles, and two quickly deteriorated. Even the histories of the five who generally lost the ability to function independently did not suggest that institutional life was to blame. Their initial discharge plans may have taen unduly optimistic. This research suggests that nursing home life does not prove iatrogenic for persons admitted with a pssitive prognosis. A four-page list of references concludes the document.

Background: Spleen and liver is secondary lymphoid organ that is highly sensitive to different chemicals. Widespread use of pesticides in agriculture has always been a matter of concern.  And surprisingly, atrazine distinguishes out for being used more frequently among numerous harmful pesticides. As a result, long term exposure to atrazine and other pesticides is thought to produce metabolic abnormalities; however, little is known about how atrazine affects the spleen and liver and how this relates to its histo-achitectural structure.
Aim: The histopathology of the spleen and liver from rats exposed to atrazine was the subject of our investigation.
Materials and Methods: Twenty male wistar rats ranging from 150-200g were acclimated to laboratory conditions for 14 days, following which they were randomly assigned into 4 groups 1, 2, 3 and 4 of 5 animals each based on average body weight. Groups (2-4) were administered atrazine via oral route corresponding to 1237 mg/kg (20/5 LD50), 618 mg/kg (10/5 LD50) and 309 mg/Kg/body weight (1/10 LD50) for 7, 14 and 30 days, while group I (control) received distilled water orally using orogastric canula for 30 days . The liver and spleen from each group of rats were harvested, weighed, and fixed in 10% buffered formal saline fixative before being taken for histological examination 24 hours following the experimental periods of oral administration of the extract.
Results: At the end of the experiment, the histological findings showed increased and numerous area of the white pulp of spleen from rats exposed to atrazine as compared to that from the control. The relative area of germinal centre in the structure of the splenic lymph follicles of rats exposed to atrazine also revealed increased. Also, Histo-pathologically, the liver showed necrotic hepatic cells and congested central vein, with the highest atrazine concentration causing the most adverse effects.
Conclusion: Our data demonstrated that rats exposed to high-dose of atrazine led to hypertrophy of white pulp of the spleen and hepatic cell damage with liver. From this we concluded that both organ are highly sensitive to the debilitating effects of atrazine.


Editor—Thornton et al say that claims for the reduction in relative risk of death from breast cancer among women who are screened have ranged from 63% to 6%.1 This is crucial information for women considering attending. Unfortunately the lower limit, attributed to our paper in the BMJ in 2000,2 is no such estimate. The 6% refers to the reduction seen in death rates from breast cancer for invited women (including those screened and non-attenders) in 1998, from a programme that started between 1988 and 1995.

For reasons we explained in great detail in our paper (including the fact that many deaths in the 1990s will have been women with a diagnosis of breast cancer before any invitation to screening), this is most likely to estimate the beginnings of an effect—not the full effect. It is therefore inaccurate and extremely unhelpful to quote this figure to women as an estimated relative risk reduction from attending screening—it is not.


By examining three different models of commercial agriculture – a plantation, a commercial farming area, and an out-grower scheme – we observe heterogeneous impacts on different segments of rural communities. Each produces gender and generational differentials in employment and other income-earning opportunities. Our study supports the hypothesis that the plantation model typifies the 'enclave' economy that is poorly integrated into the surrounding communities and the local economy. While out-grower schemes have often been favourably compared to plantations, our evidence on the Magobbo sugarcane out-grower scheme points to the contrary: its block farming model consolidates smallholdings and creates a peasant-shareholder class. Shareholder 'out-growers' receive dividends from what is essentially an extension of the plantation. This accumulation for a few also produces land scarcity and fragile semi-proletarianised livelihoods for others. By contrast we find that the commercial farming model, while based on an elite form of large-scale commercial farming, does provide benefits to surrounding areas, through employment and local economic linkages.

Two mi xed-ligand oxovanadium(lV) complexes VO(A)(B) [where H2A=salicyli c acid and B=2,2'-bipyridine or I , 10phenanthrolin e (hereafter, bipy and phen respectively)] have been synthesized and characterized by magnetic moment and spectral (JR, UVIV IS and EPR) data. The Aion acts as a bidentate dinegati ve ligand while B ligands act as a neutral bidentate. The magnetic susceptibility values indicate the existence of a small amount of anti ferromagneti c interaction. The vanadium atoms in the complexes are hexacoordinated and the coordination sphere is of the type [VO(OO)(N N)], where 0 atoms are of oxQ., carboxylic and phenolic type and N atoms are of pyridine type. The sixth coord in ation site is occupi ed by phenol ic oxygen of the neighbouring molccul e forming a bridge. The vv~o confimls the hexacoordinati on.

The dynamic equations of degradation of organics by EM(effective microorganisms)was studied with prepared water sample as the object of treatment. The results show that growth of effective microorganisms is in accordance with zero-order kinetics when the concentration of substrate is much higher than Monod constant and is in accordance with first-order kinetics when the concentration of substrate is much lower than Monod constant.


This paper tests for the stock market reaction to corporate debt-based securities offering. A standard event study framework is applied to calculate and test Average Abnormal Returns (AARs) and Cumulative Average Abnormal Returns (CAARs), both on and surrounding the announcement date. A noteworthy conclusion is the absenteeism of significant positive abnormal returns for events surrounding the issue date. Conversely, negative abnormal returns are reported where the AAR is negative on the announcement issue date and remains negative three days thereafter. As for the GCC case, such market behavior reflects the controversy about debt-based securities (Sukuk) and their full compliance with Islamic Law. In line with CAARs, the tests indicate insignificant results, including bounded asymmetric and symmetric event windows for periods before and after the announcement date, concluding insignificant CAARs, hence, no wealth effect. Within the equity marketplace, these results will be of practical relevance to corporations, practitioners and decision-makers.


The utility model relates to an urban gas pipe network leakage wireless monitoring system based on acoustic emission. The system comprises a pipeline leakage monitoring unit, a Zigbee center node, a GPRS data receiving terminal and a computer control system, wherein the pipeline leakage monitoring unit is used for detecting gas leakage signals in an urban gas pipe network. The Zigbee center node receives the gas leakage signals through a Zigbee wireless network and sends the signals through a GPRS wireless network. The GPRS data receiving terminal receives the signals sent by the Zigbee center node and then sends the signals to the computer control system, and then the gas leakage positions are acquired. According to the urban gas pipe network leakage wireless monitoring system, the urban gas pipe network can be continuously monitored in real time, the pipeline operating state can be comprehensively and systematically controlled, and monitoring efficiency is improved. The Zigbee wireless network and the GPRS wireless network are utilized to transmit signals, and the urban gas pipe network leakage wireless monitoring system has the advantages of being large in transmission distance, flexible to deploy and easy to maintain.


With the rapid development of information society, a large amount of vague or uncertain English interpretation information appears in daily life. Uncertain information processing is an important research content in the field of artificial intelligence. In this paper, we combine the three-branch concept lattice and linguistic values with the digital elevation model and propose the three-branch fuzzy linguistic concept lattice as well as the attribute approximation method. In this paper, an improved serial algorithm for sink accumulation is proposed. The improved algorithm changes the order of cell calculation; after the cumulative amount of a "sub-basin" is calculated, all cells of the next "sub-basin" are calculated until all cells are calculated. The improved algorithm reduces the overhead space in the calculation process, reduces the pressure of cells entering and leaving the queue, and improves the calculation efficiency. The improved cumulant algorithm is compared with the commonly used recursive cumulant algorithm and the nonrecursive cumulant algorithm, and the improved algorithm improves by about 17% compared with the nonrecursive algorithm at 106 cell level, and the computation time of the recursive algorithm is about 3 times of the improved algorithm. Because the sink accumulation serial algorithm is an important part of the parallel calculation of sink accumulation, and the execution time is shorter by using the improved algorithm, this paper applies the proposed improved accumulation serial algorithm to the process of parallel calculation of accumulation.


Microencapsulation is widely used to stabilize probiotics to allow their full functioning. The aim of the study was to determine the optimal combination of Bambara groundnut protein isolate (BGPI)/alginate and inulin as the encapsulating agents for the probiotic; L a c t o b a c ill u s r h a m n o s u s GG was established using response surface methodology (RSM). The probiotic cells were encapsulated in various ratios of BGPI/alginate-inulin wall according to RSM with complex coacervation technique. It was found that the optimal concentration level of 1:1 weight ratio BGPI/alginate solution was 2.14% w/v with 3.23% w/v inulin. The formulation yielded 96.64% encapsulation efficiency, having survival rate as high as 95.76% and 94.48% after freeze drying process and after exposure to acid condition respectively. Not only was the validity of the in-use predicted model confirmed but capsules also improved the survival rate of the cells in simulated gastric fluid (SGF) by ∼ 4.88 log CFU/ml after 3 h compared with free cells and demonstrated the cell release of 8.53 log CFU/ml within 4 h. The survival rate of entrapped cells stored at 4°C and 30°C for 6 months (7.82 log × FU/ml and 8 log CFU/ml, respectively) were superior to those of free cells in the identical conditions, (4.10 log CFU/ml and <1 log CFU/ml respectively). Encapsulation of probiotics in BGPI/alginate-inulin capsules offers opportunities for improving the viability of cells during freeze drying process, exposure to the acidic medium of the stomach and storage.


The mistake of using the Chinese adverb "ye" is common for Korean oversea students.There are often four kinds of incorrect usages: omitting,wrong order,mix-up or overused.From the particularity of Chinese teaching to the oversea students,the four items of its usages by Lu shuxiang and the two kinds and four items of usages by Ma zheng can be combined into two items of usages,that is,"ye" is used inside the sentence to show the similarity and the other is "ye" used outside the sentence to show euphemism so as to fit the Chinese teaching.


Football emerged in England in the 19th century and today is one of the most
practiced sports in the world and the Champions League of Europe stands out to
house some of the greatest teams of the present time. The aim of this study was to
compare the number of goals scored and the number of goals scored between the
Champions League teams. Materials and methods: Google and search engines were
used as search engines. Six teams won the competition between 2007-2018 and
analyzed the number of goals scored by the ball rolling and the ball stopped between
the team and all the champions teams of the analyzed period. Result: The results
show that Real Madrid was the team that obtained the highest number of goals
scored in the average, with both the ball rolling and the goals of the ball stopped in
2018 (ball rolling = 3.15 and ball stopped = 1, 57). Conclusion: This study showed a
trend towards increasing elevation both of goals of stopped balls and of goals of balls
rolling in the champion teams of the Champions League of Europe during the
analyzed period.


This study is the first in a three-year sequence examining the introduction of instruction about text structure within classrooms using a process-oriented approach to writing. The first year's study focused on the effects of an instructional intervention introducing sixth-grade students to a strategy for gathering and organizing information based on compare and contrast text structures. The three-week intervention integrated research on text structures with instructional research on sensitizing students to sources of information for answering questions. As a result of the intervention, students showed improvement on three dependent measures: free recall of a compare/contrast passage, summarization across multiple passages, and free writing. A questionnaire administered during instruction indicated that students had internalized the questions guiding information-gathering for compare/contrast activities. Results are discussed in terms of direct tests and both near and far transfer.


A study was conducted on softwood cutting of Catalpa bungei considering the rooting rate and rooting trait by using Yuanjichangguo(Long-fruit and round-base) Catalpa as cutting material in automatic control greenhouse,with controlled air temperature 18—28 ℃ and humidity of 90%—95% during the rooting period.Two kinds of hormones of ABT-1 and NAA were used in different concentrations,treating methods and treating durations,and four kinds of mediums of peat,perlite,sand and vermiculite were adopted in different mixing proportions for the study.The results showed that high rooting rate and good rooting trait were achieved when softwood cuttings were treated with quick dipping of 1 000 mg·kg-1 ABT-1 or 1 000 mg·kg-1 NAA hormone with talc powder mixture,and when the medium mixture of peat∶ perlite = 1∶ 1 was employed.The highest rooting rate of 83% was achieved from the best combination of appropriate hormone treatments and medium mixture for the softwood cutting of C.bungei.The study results can be important references to promote the rooting rate in developing rooted cutting plants of Catalpa bungei.


Recommendation systems improve users' online shopping experience by recommending relevant items from a large pool of items in different categories. Fashion recommendation systems apart from recommending individual fashion items also recommend fashion outfits. In this work, we consider the problem of the outfit compatibility prediction task, an integral part of the fashion outfit recommendation system. A compatibility prediction module determines whether all the items in an outfit are visually compatible with each other and match the user's preferences. Existing approaches can be grouped based on the representation scheme: (i) pair-wise and (ii) set or sequence. Pair-wise representation does not consider the outfit as a whole, and the sequence representation approaches are sensitive to the ordering of the items. Further, these methods do not explicitly capture the visual relationship between the items. We propose a novel method for the personalized outfit-compatible prediction task. The proposed method represents the outfit as a graph and uses a dot-attention graph neural network to capture the visual relationship between items. The graph read-out layer generates the final outfit embedding. A novel approach is proposed to model the user's preference for different styles. The final outfit compatibility score is generated by computing the similarity between outfit embedding and user embedding. Experimental results and ablation study on the Polyvore-U dataset, highlight the effectiveness of the proposed method.


The invention relates to a control method for online predication of a surface crack of a continuous casting sheet billet. The online predication of the surface crack is carried out by building a temperature detection system on thermocouples on the wall surface of a crystallizer and comparatively analyzing the temperature change conditions in different positions in the heat transfer direction, so that the predication accuracy is high, the surface crack of the continuous casting sheet billet and the specific location of the surface crack are accurately predicted, and the control method is used for guiding on-site production to reduce the quality defects and improve the quality of the continuous casting sheet billet.


IN APPLYING the maximum likelihood method of estimation to data based on the MNS series of genes, it is apparently necessary to use an iterative procedure in computing the estimates of the gene frequencies (Boyd, 1954; Mather, 1951; Stevens, 1938). The general method is to begin with easily computed but inefficient gene frequency estimates and, through a sequence of adjustments depending on the variancecovariance structure, deduce the values of the efficient maximum likelihood estimates. Explicit expressions for the variances and covariances would, therefore, be of value in simplifying the algebraic manipulations necessary for finding these estimates as well as in evaluating their reliability. We denote the frequencies of the four genes involved in the MNS system by mi8, min, n.8, and ns, and the observed proportions of individuals in each of the six phenotypes by M, MS, MN, MNS, N, and NS. The expected values of these proportions are


The equilibrium Josephson current through a nanoscale multilevel quantum dot with Rashba or Dresselhaus spin-orbit coupling $\ensuremath{\alpha}$ has been computed. The critical current can be drastically modified already by moderate $\ensuremath{\alpha}$. In the presence of a Zeeman field, Datta-Das-like oscillatory dependencies on $\ensuremath{\alpha}$ are predicted.
