Source of material: Reaction of 2.48 g 2,2'-dibromo-l,r-binaphthyl with 8.27 ml of n-butyllithium (hexane sol. 1.6 M) at 243 Κ and 3.17 ml of (CH3)3SiCl in thf at 195 K. The mixture was allowed to warm to RT overnight and was then hydrolysed with water. Usual work up and recrystallisation from toluene yielded 78.3 % of the title compound (see réf. 1). There are two independent molecules in the asymmetric unit. The packing of the molecules is dominated by the naphtylgroups. The aromatic systems form planes which are orientated right-angled to each other. The coordination of the Si-atoms is tetrahedral and the atomic distances arc in the normal range (185-190 pm). A possible split position of the two methylgroups C25, C26 was not refined.


Voice problems are common in occupations where there is noise, dust, odours or fumes and microbial contamination. The purpose of this study is to find out the prevalence of hoarseness, its changes over the follow-up and the effect of the remediation on the prevalence. A total of 13 health care buildings were followed, 10 with indoor air problems and 3 as reference buildings. Three buildings were thoroughly remediated, and their effects were analyzed. A health questionnaire was used, before and after the remediation. Blood samples and skin prick tests were performed on all volunteers. Based on findings, 17.0% of the respondents reported hoarseness at least every week. The skin test findings for common environmental allergens, moisture damage microbes and mites were approximately similar in the exposed and reference groups, respectively. Hoarseness had a strong correlation with indoor air problems. Before the remediation, hoarseness and voice problems were more prevalent in the problem buildings. After the remediation, hoarseness was reduced by 50%. In conclusion, this study shows a connection between indoor air exposure and technical damage in buildings. The remediation significantly reduced the prevalence of hoarseness. Mould allergy is rare and does not explain the voice problems.


We investigate a class of quadratic Volterra filters, which can be used as computationally efficient edge detectors. Filters from this class are approximately equal to mean-weighted highpass filters, and therefore, they extract fewer edges from dark areas, which is a desirable property for many image enhancement applications. We study the one-dimensional case first and then generalize the results to two dimensions. Since the four-dimensional frequency response yields little insight in the properties of these filters, we also develop a technique for characterizing these filters in a more intuitive way. Using the observation that they map sinusoidal inputs to constant outputs, we employ two-dimensional oriented sinusoids to assess both the frequency characteristics and the degree to which a filter is isotropic, i.e., independent of the input orientation.<<ETX>>

ABSTRACT Objectives: Recent research demonstrates that lactate dehydrogenase (LDH) activity within the normal range may serve as a mediator in the (positive) relationship between physical activity and cardiovascular disease risk. Emerging work supports deleterious associations between sedentary behavior and health, independent of physical activity. Thus, this study evaluated if sedentary behavior was associated with normal-range LDH activity, independent of physical activity. Methods: Data from the 2003–2006 NHANES were used (N = 2,087 adults; 40–79 yrs). LDH activity levels were estimated from a blood sample using LX20 and LDH reagent; participants were included if they had LDH activity levels within the normal range (105–333 IU/L). Physical activity and sedentary behavior were assessed via accelerometry. Results: Sedentary behavior was inversely associated with normal-range LDH activity when physical activity was excluded from the model (OR = 0.89; 95% CI: 0.83–0.97, P = 0.009 for LDH activity quartile 4 vs. 1). However, sedentary behavior was no longer associated with normal-range LDH activity after controlling for physical activity and other covariates (OR = 1.00, P = 0.49 for LDH activity quartile 2 vs. 1; OR = 1.00, P = 0.72 for LDH quartile 3 vs. 1; and OR = 0.99, P = 0.36 for LDH quartile 4 vs. 1). Conclusion: Unlike physical activity, sedentary behavior is not independently associated with normal-range LDH activity.


As the microelectronics industry strives to achieve smaller device design geometries, control of linewidth, or critical dimension (CD), becomes increasingly important. Currently, CD uniformity is controlled by exposing large numbers of samples for a fixed exposure time which is determined in advance by calibration techniques. This type of control does not accommodate variations in optical properties of the wafers that may occur during manufacturing. In this work, a relationship is demonstrated between the intensity of light diffracted from a latent image consisting of a periodic pattern in the undeveloped photoresist and the amount of energy absorbed by the resist material (the exposure dose). This relationship is used to simulate exposure dose control of photoresist on surfaces which have different optical properties chosen to represent surfaces typical of those found in operating process lines. Samples include a variety of photoresist materials and substrates with a wide variety of optical properties. The optical properties of the substrates were deliberately varied to determine the effect of these properties on CD (in the presence and absence of an exposure monitor) during lithography. It was observed that linewidth uniformity of the developed photoresist can be greatly improved when the intensity of diffracted light from the latent image is used to control the exposure dose. Diffraction from the latent image grating structures was modeled using rigorous coupled wave analysis. The modeling is used to predict the diffraction from a latent image as a function of the substrate optical properties and the parameters of the latent image (i.e., linewidth, sidewall angle). Good agreement is obtained between theoretical and experimental observations. Conversely, the inverse problem is solved in which the parameters of the diffracting structure (the latent image) are determined from a measurement of the diffracted power. Therefore, the diffracted power can be monitored for the purpose of determining when the latent image will produce the proper CD upon development.


We report the investigation results of reproductive biology of the Black Sea lizard Darevskia pontica in the valley of the Malaya Laba River (Northwest Caucasus). Based on allocation of groups in size and color, we assume that these lizards begin to reproduce after the second hibernation. Adult females of the Black Sea lizard are statistically superior to the males in body length and weight. Females collected in nature from the III decade of May to the I decade of June laid eggs in the laboratory in the II – III decades of June. In the nature, eggs were found also in the II–III decade of August. The body length of the females which brought the offspring was equal to 50,4–57,3 mm. Clutches contain 3–7 eggs with a mass of 0,21–0,45 g and size of 9,0–10,8×5,1–6,4 mm. Incubation in the laboratory conditions lasted for 40–47 days. Newborn lizards had a mass of 0,20–0,36 g and a body length of 20,2–26,5 mm.


An archaeozoological analysis of mammal remains recovered from the dwelling units and streets of ancient Porphyreon excavated in 2009, 2010 and 2012, gives insight into the importance of mammals for the residents of this quarter in succeeding periods: from the Iron Age through the Persian and Hellenistic periods to Byzantine times. Husbandry lay at the base of the animal economy and was supplemented with hunting various species of gazelle. Cattle, sheep and goat were the most numerous livestock species represented in the archaeological record. The high percentage of cattle observed in Iron Age deposits could have resulted from the agricultural lifestyle of the population. Starting from the Persian period, sheep and goat played the most prominent role in the animal economy, implying a pastoral model of husbandry. Raising goats for meat was more significant initially; from the Hellenistic period onwards, the number of sheep reared for milk and wool increased. Pigs constituted a minor percentage of the livestock. The presence of equid remains, including horse and donkey, was confirmed for the Persian period, when these animals were used for transportation.


In this paper we proposed a prostate segmentation and also tumour detection using deep neural networks. The cutting-edge deep learning techniques are useful compared to the challenges of machine learning based feature extraction techniques. Here we proposed a strategy that contains an FCN model that incorporates data from several MRI images, allowing for faster convergence and more accurate segmentation. T1 and DWI volumes may be used together to delineate the prostate boundary, according to this study. Second, we investigated whether this method might be utilized to provide voxel-level prostate tumor forecasts. The cascaded learning method and performed tests to demonstrate its effectiveness.

Bilingualism is a subject of close attention to many scholars. According to statistics, the English language by popularity is in first place among bilingual speakers. Kazakhstan's education policy also relies more on reforms for the development of a bilingual society on the principle of language constructions – Kazakh – English, Kazakh – Russian. In this article, we consider social factors, contributing to the development of bilingualism in the period of professional formation of Kazakhstan youth. This article provides a review of scientific literature, the results of the experiments carried out earlier in some countries of the world, and the results of a pedagogical experiment carried out by teachers of the English language at Aktobe Regional State University named after K. Zhubanov (Kazakhstan). Based on the findings, the authors of the article discovered that for students, motivational, environmental and academic factors of learning a foreign language as a method for intercultural communication, also as an instrument, allowing to expand opportunities for career development or getting prestigious work are important.

Objective
To investigate the preoperative plus postoperative neutrophil-lymphocyte ratio (PP-NLR) predicts the outcomes of hepatocellular carcinoma after hepatectomy.

Methods
The clinical data of 44 patients with partial hepatectomy in the Hepatobiliary Surgery, Beijing Tsinghua Changgung Hospital, Tsinghua University, from December 2014 to March 2018 were retrospectively analyzed. According to the cut-off value, the high NLR is assigned a value of 1 before and after surgery, and the low NLR is assigned a value of 0. Preoperative NLR plus postoperative NLR=0/1/2. The preoperative NLR plus postoperative NLR=0/1 was assigned to one group, and the preoperative NLR plus postoperative NLR=2 was attributed to one group. Recurrence-free survival (RFS) and overall survival (OS) were evaluated by the Kaplan-Meier method, with comparisons using the log-rank test. The Cox proportional hazard model is used for univariate and multivariate analysis.

Results
Comparison of clinical and pathological data of different PP-NLR, the preoperative and postoperative NLR was higher in the PP-NLR=2 group than in the PP-NLR=1/0 group, and the difference was significant (P<0.05). Univariate analysis showed that PP-NLR (HR=3.495, 95%CI: 1.054~11.589, P<0.05) and degree of differentiation(HR=3.995, 95%CI: 1.050~15.198, P<0.05) were risk factors for OS after liver resection, while preoperative NLR and postoperative NLR alone were not risk factors for overall survival. Multivariate analysis showed that PP-NLR (HR=4.733, 95%CI: 1.320~16.966, P<0.05) and degree of differentiation (HR=6.310, 95%CI: 1.456~27.344, P<0.05) were independent risk factors for OS after liver resection.

Conclusion
PP-NLR considers the systemic immune status of preoperative and postoperative, predicts prognosis better than preoperative or postoperative NLR.

Understanding the current business cycle of a nation is essential for individuals, enterprises, and the government in order to make appropriate strategic decisions and take advantage of business opportunities. At a specific period of economic activities, the business cycle develops moderately and may lead to negative growth or economic recession when the economic activity expands to the peak. Business cycle functions as an indicator for the economic development of a nation and thus, it is an important tool for decision-makers. For example, the situation of the business cycle in Taiwan is acquired from the cyclical indicators, economic monitoring indicator, and reference dates of business cycles in Taiwan periodically announced by the Council of Economic Planning and Development (CEPD). This information provides a reference for individuals and investors to make decisions. Since business cycle is fuzzy in nature, this study uses the fuzzy regression analysis method to establish a regression model in order to provide a reference for enterprises and decision-makers to make the right investments.


Abstract Context: Exercise increases the levels of circulating inflammatory mediators. Objective: Does an acute bout of exercise affect the mRNA gene expression level of inflammatory markers in peripheral blood mononuclear cells (PBMCs) and contribute to the circulating levels of inflammatory mediators? Materials and methods: Ten healthy, non-smoking men (22–28 years old) performed 1-hour cycling at 70% of VO2 max. Results: The gene transcripts of CXCL16, IL-1β, IL-8, COX-2, TXB21 and GATA3 were significantly up-regulated in PBMCs. Serum levels of CXCL16, IL-6, TNFα and IL-10 were also significantly increased after exercise. Discussion and conclusion: Increased mRNA transcription of inflammatory genes in PBMCs may contribute to increased level of inflammatory markers after an acute bout of exercise. The increased mRNA levels of GATA-3 and TXB21 may indicate that T cell lymphocytes are activated and secrete cytokines into the circulation. It needs to be further investigated if exercise changes the Th1/Th2 balance.


Shoot extracts of Pistacia lentiscus (P. lentiscus ) were investigated for its medicinal importance, by valorizing of some chemical characterization, mineral composition, and study of the antioxidant activity. The photochemical screening of the plants constituents were assessed by using qualitative tests were conducted for the presence of the following active components: alkaloid, Hydrolysable tannins, tannins, phlobatannins, phenol, flavonoids, glycoside, saponins, volatile oil, hydrolysable tannin, protein, cortisone and Anthracanens (anti-oxidation compound) . All were present. Mineral contents of shoot extract were determined by Atomic Absorption Spectrophotometer. The highest levels of potassium (K) and Iron (Fe) were found in Shoot of P. lentiscus from Libya. These findings suggest that shoots of P. lentiscus are potential sources of Iron, potassium and antimicrobial compounds. Also it has a great medicinal value due to the presence of anti-oxidation compound and cortisone.


Some remarks on the quantum theory of the negative hydrogen ion are made, and attention is drawn to certain facts which make the evaluation of its continuous absorption coefficient a problem of extreme difficulty.


The Association of Clinicians for the Underserved (ACU), a national organization whose mission is to improve the health of underserved populations and enhance the development and support of health care clinicians serving these populations, received funding from the Robert Wood Johnson Foundation and the webMethods Foundation to develop an oral health continuing education project to engage nondental clinicians and parents in the prevention of early childhood caries (ECC), formerly known as baby bottle tooth decay. The following is a report on this project. Early childhood caries is a disease preventable through early detection and proper oral hygiene. It is the most common chronic childhood disease and is the most prevalent unmet health need among children, disproportionately affecting minority and underserved populations. A majority (80%) of all ECC is experienced by 24% of the general population, made up mostly of lower income, minority group members. Poor dental health results in pain, infection, oral dysfunction, and poor performance in school. According to the U.S. Surgeon General's report on oral health, over 51 million hours of school are lost each year due to dental illness. Because of this obvious health disparity and the severity of the problem, the ACU sought funding to increase primary care provider knowledge and ability to provide screening and for anticipatory guidance in the prevention of ECC. Sharing work of dentistry and medicine, an instance of transdisciplinary care, must be a matter of concern for anyone who is committed to eliminating oral health disparities and subsequently improving the well-being of children. Many primary care providers simply do not have the clinical comfort or competence to provide oral health services without participating in training workshops such as those


Purpose & Background: Posteroanterior mobilisation (PA) is a manual physiotherapy technique that is commonly used as an examination tool and a form of conservative treatment for spinal complaints. The efficacy of this technique is controversial and this may be in part due to a limited knowledge of the mechanical and physiological mechanisms underlying this technique. This study aims to evaluate the ability of interventional MRI to image the mechanics of mobilisation in terms of spinal movement and soft tissue deformation during a PA mobilisation. Methods: 5 normal subjects (4 female, 1 male, mean age 29.6 ± 3.9 years) with no current or history of neck pain requiring intervention were recruited into this study, and written informed consent obtained. Subjects were scanned using a General Electric Signa SP10 Interventional MRI scanner (iMR). This is an open MRI scanner consisting of 2 connected but opposing ring "doughnut" magnets. The gap between these magnets is 56 cm generating a uniform field of 0.5Tesla. Subjects were scanned in the prone position with their necks in either a neutral or flexed position. In each position, subjects underwent a PA mobilisation to the 2nd and 6th cervical vertebrae. Sagittal and axial images of the spine were obtained prior to, during and following the mobilisation. Measurements of intervertebral rotation and translation were obtained from the sagittal images, and measures of soft tissue compression with respect to the spinous process were obtained from the axial images. Paired analysis of variance was used to investigate the impact of the mobilisations in each position. Results: Clear images of vertebral position could be obtained if the mobilisation was sustained once the appropriate force had been delivered. From these images, it is possible to measure vertebral angulation, translation and soft tissue compression. From these measures, it became clear that intersegmental vertebral angulation and translation did not alter as a result of the force applied regardless of cervical position. However, marked and significant changes were seen in terms of soft tissue compression and in some instances overall angulation of the cervical spine. Conclusion: This pilot work suggests that it is feasible to use iMR technology to study the mechanics of spinal mobilisation. Preliminary findings suggest that there is little or no displacement of the vertebral bodies as a result of an AP mobilisation, although there is considerable soft tissue compression.


Tactile sensation of the human hand was measured using two methods : static two-point discrimination test (s2PD) and moving two-point discrimination test (m2PD). The volar side of the right hand of ten subjects (21-24 year old men) was divided into 29 areas each, according to the location of finger joints and the innervation regions of peripheral and peripheral nerves. The shortest threshold of s2PD was measured in the 2nd distal phalanx, which value was 1.4 mm±0.5 mm, and the shortest threshold of m2PD was also measured in the 2nd distal phalanx, which value was 0.7 mm±0.5 mm. In all 29 areas, the threshold of m2PD was significantly (P<0.01) shorter than that of s2PD. That is, the dynamic stimulus allows generating much response of mechanoreceptive afferent units than the static stimulus. The strong correlation (r=0.95) was found between the threshold of s2PD and that of m2PD on the volar side of human hand.


Using 1987, 1996, and 2004 data, we show that the gender pay gap in the Chinese urban labor market has increased across the wage distribution, and the increase was greater at the lower quantiles. We interpret this as evidence of the "sticky floor" effect.We use the reweighting and recentered influence function projection method proposed by Firpo, Fortin, Lemieux (2005) to decompose gender pay differentials across the wage distribution. We find that the gender differences in the return to labor market characteristics, also known as the "discrimination effect" or "unexplained gender pay gap", contribute most to the increase in the overall gender pay gap. The Firpo, Fortin, and Lemieux method allows us to further decompose the gender pay gap into the contribution of each individual variable. We find that the "sticky floor" effect may be associated with a particularly low paid group of female production workers with relatively less education working in non-state owned enterprises.

Subaqueous gypsum (CaSO4·2H2O) crystals are relatively common in epithermal systems where sulfide ore deposits are present. The Giant Geode of Pulpí (Almería, SE Spain) hosts some of the largest (up to 2 m in length) subaqueous gypsum crystals discovered to date. Here, we present the first U-series ages of its crystals and reconstruct the oxygen and hydrogen isotopic composition (δ18O and δ2H) of the Pulpí paleo-aquifer from which the crystals formed by using stable isotopes of gypsum hydration water. We successfully dated the onset of gypsum precipitation in the Geode at 164 ± 15 ka. However, the extremely low U concentration (<11 ppb) and relatively high detrital Th content (230Th/232Th < 3.2) hinder accurate dating other gypsum samples. The δ18O and δD values of the paleo-aquifer during the growth of the crystals aligned with the local meteoric water line, suggesting that the sulfate-enriched mother solution consisted of meteoric water that recharged the aquifer during that period. The mean isotopic composition of the Pulpí paleo-aquifer (δ18O = −6.5 ± 0.1‰ and δ2H = −42.3 ± 0.5‰) during the formation of the crystals was similar to the current groundwater in this area (δ18O = −6.1 ± 0.8‰, δ2H = −42 ± 6‰). The isotopic differences observed in samples collected from distinct locations and in individual crystals were probably related to changes in the isotopic composition of the aquifer, as a consequence of varying climate that impacted on the isotopic composition of rainwater during thousands of years in this region. Our results indicated that subaqueous selenite crystals may be useful for paleo-hydrological reconstructions. However, improving the current analytical techniques for dating gypsum with low U concentrations will be essential to obtain accurate and reliable records from Quaternary gypsum cave crystals in the future.


This paper investigates the abilities of locally dispersed heat pumps connected to a thermal heat storage to perform demand-side management activities in an existing urban low voltage distribution grid in Germany. To do so, a model is developed using DiGSILENT PowerFactory to simulate the operation of a heating system incorporating an air-to-water heat pump connected to a thermal heat storage by performing a dynamic simulation. By applying two different modes of operation, a so called state-of-charge control and a demand-side management control, the weighted average transformer loading is calculated and compared. Results imply that heat pumps even at low penetration levels provide considerable load-shedding potentials and are hence able to reduce peak loads significantly. Moreover, the limiting effects of heat storage sizes are demonstrated. It is further shown, that lower ambient temperatures reduce the demand-side management potential of heat pumps.

This paper presents a brief historical review of studying the Stone Age osteological materials in the world, Russia and the Trans-Baikal region. Since the given issue has not been elaborated yet and there exists only fragmental literature on this subject in the Russian science, the author attempts to generalize the matter. Taking into account the Russian and foreign researchers' works the evolution of ideas about the fossil fauna has been traced from the primitive interpretations to its recognition as an important source of information about the animal world and its interaction with human society. While characterizing the present state of this field of study the author emphasizes the researchers' desire to extract as much information as possible from faunal remains that is impossible without interdisciplinary research. The final part of the work is a review of osteo-archeological researches in the Trans-Baikal region. The author offers to compensate for poor preservation and small number of osteological materials in the region by their careful study, the use of modern methods (such as biometric, taphonomical, palaeontological, technological, typological, bio-geographical, trace examination, etc.) as well as the systematization of the Pleistocene fauna sites. These solutions will help in finding new well-preserved sites and add considerably to the data about the ancient inhabitants of the Trans-Baikal region and their history.


Due to its comprehensive urban functions, high population density, and unreasonable parking space planning, the old town of Hefei is facing a serious problem of uneven distribution of parking spaces. This paper analyzed the current parking situation in the old town of Hefei through the survey results of the current parking situation in the old town. Then, based on the parking generation rate model, considering the impact of price factors and parking service levels on parking demand, a parking generation-prediction model was established to predict the parking demand in the old town of Hefei and the parking demand of each traffic district was obtained. The results show that the contradiction between the supply and demand of parking in the old town of Hefei is still prominent in the future.

The invention concerns a process for producing and purifying perylene-3,4-dicarboxylic acid imides by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: reaction is carried out in the presence of a tertiary nitrogen base compound as the solvent and a transition metal or transition metal salt as the catalyst. The invention further concerns the purification of perylene-3,4-dicarboxylic acid imides obtained by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: the raw products are first heated in N-methyl pyrrolidone, the N-methyl pyrrolidone adducts thus produced are treated with a base in the presence of an organic diluting agent, and the products subsequently isolated undergo further treatment if necessary with an aqueous acid. The invention also concerns novel perylene-3,4-dicarboxylic acid imides and the use thereof as fluorescence dyes, pigments or pigment additive precursors.


Controlling the morphology of bimetallic nanoscale systems at the atomic level is of utmost importance in fields such as nanocatalysis, plasmonics, or optics. In this report we emphasize an experimental observation of superlattice formation in bimetallic gold–palladium nanocubes of the order of 30 nm synthesized by a seed-mediated growth method. By combining our experimental observations based on high-angle annular dark-field scanning transmission electron microscopy and nanobeam diffraction, we have established that a process of galvanic replacement takes place in our third deposition step, triggering the formation of vacancies and atomic diffusion, triggering short-range ordering in our three-layer AuPdAu nanocubes.


Sections 3 and 4 of the 1988 Education Reform Act include history as one of the compulsory foundation subjects in the National Curriculum and empower the Secretary of State to specify attainment targets, programmes of study, and assessment arrangements for history for children of compulsory school age. The History Working Group appointed to advise the Secretary of State on history reported in January and its recommendations for attainment targets, programmes of study and statements of attainment were published in April in its final report. Michael D. Wilson, deputy head, Carr Hill School, Kirkham, Lancashire, and author of History for Pupils with Learning Difficulties, comments on the recommendations in relation to special educational needs.


Cervical incompetence in the mare is widely recognized as a major cause of pregnancy failure. Failure to attain adequate closure during pregnancy is a key predisposing factor to ascending placentitis. In humans, cervical insufficiency is of major concern and can result in preterm birth and lateterm abortions, similar to observations in mares. Emerging clinical and laboratory-based evidence suggests that focusing on the uterine cervix may provide significant elements of diagnostic value to identify patients at risk for preterm delivery, offering guidelines to implement preventive intervention. A variety of techniques have been used in human medicine to address cervical incompetence, including medical therapy with progesterone, cervical cerclage, and the placement of a cervical pessary, some of which may be applicable in the mare. A recent study in human medicine compared vaginal progesterone versus cerclage, with the use of placebo/no cerclage as the control treatment. The authors concluded that progesterone and cervical cerclage are equally effective for the prevention of preterm birth and adverse perinatal outcomes in patients with a short cervix and history of preterm birth. A common treatment strategy used on mares that have previously lost a foal because of placentitis or that have anatomical abnormalities in the caudal reproductive tract making them at risk of ascending placentitis is to administer an antimicrobial, a nonsteroidal anti-inflammatory drug and altrenogest daily until delivery of the foal. The shortcoming of this treatment is that mares may still have a preterm delivery/fetal loss with histopathological evidence of ascending placentitis despite treatment. This report describes a technique for cervical cerclage applied to a population of mares with known cervical incompetence.


The traditional formula of the rule of law is abundantly used today to test or accredit the doubtful legal nature of rules and practices that at first sight do not conform to the usual image of law. Since in its present shape the formula has been worked out in the light of modern law, the primacy of generality in law and the unity of the legal system, one may well wonder whether and to what extent it is correctly applicable to a situation of pluralism of legal orders like the one that contemporary law is developing before our eyes. In facing this issue I will start from some presuppositions without discussing them.


A system and method for continually updating a large and substantially continually changing dataset that is accessed by multiple application threads, such as a group identity database of members in communication groups of wireless communication devices. A first server holds the group identity database and, as application threads on the first server access the database to set up group communications, a second server sends new group identity data to update the database, with the new data arriving as discrete, ordered blocks. A first server-resident data-index table is updated with the ordering information of the new data blocks, and a first server-resident checkpointing thread places the ordering information of the new data blocks into a checkpoint cache and checkpoints the ordering information as the new data blocks are updated into the group identity database and verifies the ordering (or version) of the data as against the data-index table.


This paper illustrates the simulation method of evaluating the effect of system component changes on highway crash reduction. The evaluation procedure presented uses operating characteristics of a component as input, and compares the performance of alternative components in emergency traffic conflict situations. It is shown that Monte Carlo simulation of the model may be an efficient technique for comparing component alternatives. The examples presented involve (1) the emergency braking capabilities of two populations of vehicles in emergency car-following situations, and (2) two different rear lighting systems.


The U. S. Geological Survey uses the Tellurometer principally to increase the speed and reduce the costs of control surveys for topographic mapping. Increased accuracy is a welcome by-product. In this application, it largely replaces triangulation and transit-and-tape traverse. Most of our Tellurometer work consists of traverse, with angles measured by a 1-second optical theodolite.


In 2016 the UK government launched the Energy Innovation Programme, a five-year, £505 million programme that aims to accelerate the commercialisation of innovative clean-energy technologies and processes into the 2020s and 2030s. This abstract discusses the approach the Department for Business, Energy and Industrial Strategy (BEIS) has taken to evaluating this portfolio, and the lessons it has learned during the process.


It is well know that sex abusers are a very heterogeneous population, not only concerning their offending behaviour pattern, but also with regard to their personal, social and psychopathological characteristics, their life style, relapsing rate and reaction to treatment. This emphasises the basic role of psychological assessment as a process where we should detect the main deficits, personal defects an specific traits of every sex offender in order to establish an initial re-offence risk and pre-treatment base-line. These considerations were behind the Spanish version of the Multiphasic Sex Inventory (MSI) that provides our psychological vademecum with a specific tool to improve assessment of sex offenders. A sample of imprisoned offenders -104 rapists,, 43 child sex abusers and 58 non sex offenders, were assessed using the MSI and other psychological tools. While not amazing, results shoe some significant differences between samples, particularly with regard to the following variables: sexual attitudes, cognitive distortions and sexual behaviours; sex performance and preferences; and sexual orientation and background. These results may be very useful for determining the significance and magnitude of sexual deviation, the initial recidivism risk profile, and the treatment program


The development process of safety-critical systems benefits from the early identification of failures affecting them. Several techniques have been designed in order to face this issue, among them Failure Mode Effect Analysis (FMEA). Although FMEA has been mainly thought for hardware systems, the increasing responsibilities assigned to software (SW) have fostered its application to SW as well (SW-FMEA), exacerbating the complexity of the analysis. Ontologies have been proposed as a way to formalize the SW-FMEA process and to give precise semantics to the involved concepts and data. We present a framework, based on an ontological model, which, beyond other capabilities, supports the collection of SW metrics enabling automatic identification of SW components not attaining the required level of assurance.

However, growing potential of contemporary food retailers create and develop new market places and opportunities. Saturation level and an increasing homogenization also causes more competition. Surviving at the market scene and develop in a growing competitive environment has become a serious problem for food retailers and brought customer relationship management into manner. This paper aims guidance on how to deepen customer relationships contemporary food retailers of Turkey. To make a connection with your customer and deepen the relationship requires time, patience, and commitment, but building those relationships is the cornerstone of an enjoyable career as well as a business strategy that works. What they would do to deepen customer relationships on rivalry food retailer system? As a result of to help contemporary food retailers in their efforts to deepen customer relationships management strategy, it would be done by these recommendations; product bundling and relationship pricing, cross-lob data sharing and building a 360-degree customer view, sophisticated customer segmentation, real time cross –selling/up –selling - innovative reward design, automating customer care, digital revolution, big data and as a finally multi-channel seamless experience. In the context of a customer relationship strategy these tips have been examined in detail for contemporary food retailers.


Mango flowering is an important physiological event that sets the start of fruit production. Initiation is the first event that takes place for mangoes to flower. Coincident with shoot initiation, induction occurs based on the conditions present at the time of initiation. Numerous studies with mango trees support the existence of a florigenic promoter (FP) that is continuously synthesized in mango leaves and induces flowering. Translocation experiments suggest that the FP is carried from leaves to buds in phloem. Induction appears to be governed by the interaction of the FP and a vegetative promoter (VP).Mango exhibits wide variations in flowering and fruiting due to its strong dependency on environment. Flowering is decisive factor in the productivity of mango. The process associated with mango involves shoot initiation followed by floral differentiation of apical bud, and panicle emergence. Variability of mango flowering depends upon cultivar, tree age, environmental condition and growth conditions in the dry or humid tropics. Mango is the premier fruit among the tropical fruits and has been in cultivated in the Indian subcontinent since several centuries. Flowering is one aspect of mango reproductive biology that has attracted interest from researchers worldwide. The present information will helps in better understanding of flowering physiology in mango.


BACKGROUND
An increasing number of soft tissue filler procedures in the nasal region has been reported. Concomitant with demand, the number of complications has risen due to the difficulty in administering filler in a region where soft tissue layering is complex.

OBJECTIVES
To describe the layered soft tissue arrangement of the nose as it relates to the underlying arterial vasculature and to define safer zones for nasal filler enhancement.

METHODS
A total of 60 (28 males and 32 females) study participants were investigated with respect to their layered anatomy in the midline of the nose using ultrasound imaging. The presence and extent of the layered arrangement was examined as well as the depth of the arterial vasculature.

RESULTS
In the mid-nasal dorsum, a 5-layer arrangement was observed in 100% (n= 60) of all investigated cases, whereas it was found to be absent in the nasal radix and tip. The 5-layer arrangement showed an average extent of 26.7% - 67.5% in relation to nasal length. The nasal arteries coursed superficially in 91.7% of all cases in the nasal radix, in 80% in the mid-nasal dorsum, and in 98.3% in the nasal tip.

CONCLUSIONS
Soft tissue filler administration in the nose carries the highest risk for irreversible vision loss compared to any other facial region. The safety of soft tissue filler rhinoplasty procedures is enhanced by knowledge of the layered anatomy of the nose, the location and depth of the major nasal vasculature, and employment of maneuvers to decrease the risk of blindness.


A field experiment was conducted for three consecutive years (2005-06, 2006-07 and 2007-08) at the Horticulture Experimental Farm, under Precision Farming Development Centre, Department of Horticulture, AAU, Jorhat with an objective to find out the economic dose of N and K through fertigation for polyhouse grown early season capsicum and its effect on growth, yield quality and economics of cultivation under naturally ventilated polyhouse. Data of three consecutive years revealed that drip irrigation at 100% evaporation replenishment along with supplementation of 100% recommended N and K though fertigation, recorded significantly highest growth attributes, yield attributes and yield of early capsicum grown under cover in l crop, ll crop and Ill crop respectively. Pooled data averaged over the three years revealed that fertigation with 100% recommended N and K recorded 61.09% increased yield over conventional fertilization. Regarding quality parameters, significantly highest ascorbic acid content were recorded by 100% fertigation level. Study on cost economics revealed that, 100% recommended N and K as fertigation recorded the highest cost benefit ratio of 1: 1.72. Therefore, it can be inferred that for early season capsicum grown inside naturally ventilated polyhouse, irrigation scheduling at 100% evaporation replenishment through drip irrigation coupled with 100% recommended N and K (120: 60 kg/ha) as fertigation improved the growth, yield and quality of the crop with highest cost benefit ratio (1: 1.72), and may be recommended for the agro-climatic conditions of Jorhat (Assam).


Dielectric measurement and image analysis are used to evaluate the hydrophobic condition of silicone rubber surface. Hydrophobicity of silicone rubber surface was studied by using image data analysis of sprayed water droplets on the sample surface. Hydrophobicity class, HC from 1 to 7, is evaluated by the analyzed image data indices. The water droplets on the sample surface are digitized and the image indices such as size and shape factor of the droplets were evaluated. After this evaluation, 3D mapping technique is used to evaluate the HC value. The hydrophobic condition of the sample surface was also determined by measuring dielectric property of silicone rubber using a pair of inter-digital electrodes. The dielectric properties were detected by using unbalanced operation of current comparator type capacitance bridge. The changes in dielectric loss current and the capacitive current by the change in hydrophobic condition were measured for every one cycle of AC applied field. Comparing of these results can define the degradation of hydrophobicity of polymer insulator more accurately.


A simple design of a multiplierless comb decimation filter with an improved aliasing rejection and a compensated passband is presented in this paper. The aliasing rejection in the comb folding bands is improved by cascading simple multiplierless comb-based filters, with a comb filter. The simple filters introduce the additional zeros into comb folding bands, thus increasing the widths and the attenuation in the folding bands. It is interesting that the passband droop in the proposed filter and in the equivalent comb filter, are equal. As a consequence, the compensators for comb filters, proposed in literature, may be used. The method is illustrated with examples. The comparisons, with the methods from literature, are provided to show the benefit of the proposed method.


In hard real-time systems, cache partitioning is often suggested as a means of increasing the predictability of caches in pre-emptively scheduled systems: when a task is assigned its own cache partition, inter-task cache eviction is avoided, and timing verification is reduced to the standard worst-case execution time analysis used in nonpre-emptive systems. The downside of cache partitioning is the potential increase in execution times. In this paper,we evaluate cache partitioning for hard real-time systems in terms of overall schedulability. To this end, we examine the sensitivity of (i) task execution times and (ii) pre-emption costs to the size of the cache partition allocated and present a cache partitioning algorithm that is optimal with respect to taskset schedulability. We also devise an alternative algorithm which primarily optimises schedulability but also minimises processor utilization. We evaluate the performance of cache partitioning compared to state-of-the-art pre-emption cost analysis based on benchmark code and on a large number of synthetic tasksets with both fixed priority andEDF scheduling. This allows us to derive general conclusions about the usability of cache partitioning and identify taskset and systemparameters that influence the relative effectiveness of cache partitioning. We also examine the improvement in processor B Sebastian Altmeyer email@example.com; email@example.com Roeland Douma email@example.com Will Lunniss firstname.lastname@example.com Robert I.

A sedimentary core (15.50 m long) was taken with a piston corer from a barge in the centre of the crater Lake Sonachi analysed for sedimentology (magnetic susceptibility) and geochemistry (organic matter and calcium carbonate) and radiocarbon dated. Two lacustrine phases are recognized between 7,400 and 3,200 a BP and between < 2,000 a BP and the present. The first phase of high lake-level is also recorded in the neighbouring lakes Naivasha, Nakuru and Elmenteita, and in several other East African lakes. This Holocene period is also marked by some volcanic explosions.


We present continuous coupling experiments and calculations of two mutually flow-rate-coupled Belousov-Zhabotinsky (BZ) oscillators. The Ce4+-concentration of one BZ-reactor controls the flow rate into the other BZ-reactor and vice versa. Flow-rate control is proportional to the difference between the (time delayed) Ce4+-and an average Ce4+-concentration. When both period one (P1) BZ oscillators are weakly coupled, the P1 oscillations are retained in both oscillators whose periods increase with increasing coupling strength. At high coupling strengths statistically aperiodic oscillations are produced. The introduction of time delayed coupling does not reduce the noise in the strongly coupled system. We distinguish between statistical aperiodicity due to experimental noise and deterministic chaos due to the system's nonlinear dynamics. At constant coupling strength a rising delay time produces a "sawtooth" like behaviour of the P1 periods. Mutual flow-rate-coupling of two chaotic states without time delay retains chaos in both reactors at low coupling strengths. When the coupling strength increases the Hausdorff dimension passes through a maximum (≈ 2.5). At very high coupling strengths, a transition from chaos to periodic states takes place.


Most of the geographical expeditions in the XIX — early XX century,— were organized in Kronstadt — the sea capital of the Russian Empire. Many doctors of the Kronstadt Naval Hospital participated in circumnavigation and large marine expeditions on the ships of the Russian Fleet. They made a medical topographical description of more than 150 ports, coasts and other geographical locations in Europe, Asia, Africa, America, Oceania and Antarctica. Various geographical locations on the world map were named after surgeons. The names of surgeons have taken their place in history of the Russian Geographical Society and the Society of surgeons of Kronstadt. The traditions of the surgeons of previous generations are retained and enriched by the present surgeons. In 2018 the Society of surgeons of Kronstadt resumed at the Kronstadt Naval Hospital. The medical geographical description of ports, coasts, islands and other points of the vast seas and the World Ocean is one of the main and traditional lines of the Society's work.


The modern digital space is saturated with a huge amount of data in the form of images and videos every day. All information contained is important to users, organizations and other consumers. It should be noted that the speed of information dissemination is so high that sometimes, in order to trace its original source, it is necessary to spend large computing resources. Moreover, during the search for the original source, information can be distorted beyond recognition and acquire new properties in the form of details and additional links. Attackers change information, as a rule, in order to compromise an individual, incite conflicts, undermine the reputation of individuals and legal entities, etc. Among the most modern and popular means is DeepFake technology, with the help of which a person's face can be replaced on an image or video. The paper proposes a new method for generating distorted images, based on removing the background in the image, to improve the visual quality of distortion.


Abstract In this study, the rheological properties of different samples of olive oils purchased from the same producer were investigated in a wide range of temperature. In addition, at constant temperatures, the shear rate was varied to obtain heating effects. It was found that all samples reach a minimum viscosity in the temperature range of 120 - 150°C before thickening to higher viscosities. The viscosity remained almost unchanged in high shear rates regardless of temperature, indicating no shear thinning effects. No thixotropic effects were observed for the olive oils. These findings can provide insight into the microstructural, physiological and sensory changes at frying (high) temperatures.


The braid group has role in invariant of structure. Based on definition of a braid group, a permutation group and the fuzzy set, there are relation between them such that fuzzy group is well-defined. However, fuzzy group is indirect related to a braid group. In this paper, we will disclose direct relation between the braid group and the fuzzy set so that we get the fuzzy braid group by using the measurement about composition of generators of the braids.


A system and method for sensing the periodic position of one or more objects, such as rotating blades of a turbine. The system includes a passive eddy current sensing unit (variable reluctance sensor) having one or more magnets and first and second cores around which first and second coils are wound, respectively, which together generate first and second magnetic fields. The sensing unit is positioned so that the object periodically passes through the first and second magnetic fields in succession, and the first and second coils consequently produce first and second output signals, respectively. Each coil is individually connected to a processing circuitry that receives each of the first and second output signals. The circuitry electronically combines the first and second output signals so that common mode signals thereof electronically subtract from each other to eliminate from output of the circuitry any electromagnetic interference noise (common mode signals) present in the first and second output signals.


Europe's dependency on Russian gas, especially in Central and Eastern Europe, has become a major strategic liability for the West. This is especially true as the war in Eastern Ukraine has brought relations between Moscow and Brussels as well as many of the European capitals to new lows. Russia enjoys a de facto monopoly on gas supplies to the Baltic States, Bulgaria, Moldova, Serbia, and Slovakia, as well as dominating the energy scene in Hungary and other European countries. This raises serious questions with regards to the Kremlin's political influence in capitals from the heart of Europe to the Mediterranean. Allegations of corruption permeate political debates about the Russian gas supply and are putting increasing pressure on the EU and the nation-states to find economic alternatives.

Background Antiphospholipid Syndrome (APS) is a systemic autoimmune disease characterised by the presence of thrombotic and/or obstetrical manifestations and antiphospholipid antibodies (aPL). In 2006 the updated Sapporo criteria for APS were published but by now no epidemiological study on this disease were performed. Incidence and prevalence of primary APS (PAPS) in the general population are still unknown. Objectives The aim of this study was to evaluate the prevalence during the year 2013 and incidence for the period 2011–2015 of vascular PAPS in the adult population of a defined area, Valtrompia valley, using multiple sources. Valtrompia is a 40 kilometers-long prealpine valley in northern Italy. The population in 2013 was 101.477 inhabitants. The only easy access to the valley is from Brescia, the main city of the province. This valley is a cul-de-sac area without any other comfortable and practicable access. Therefore, this valley is ideal for epidemiological studies. In addition, the only Rheumatology referral tertiary Centre of the province is located in Brescia. This project was approved by the local Ethical Committee. Methods We identified adult subjects of 18–50 years old living in Valtrompia. Patients with thrombotic events were identified by two sources: 1) hospital discharge code using keywords (deep vein thrombosis, pulmonary embolism, myocardial infarction, ischaemic stroke); 2) patients with defined diagnosis of vascular PAPS already followed by the Rheumatology tertiary Centre in Brescia. Results The prevalence of PAPS in 2013 was calculated to be 35.4 (CI 95% 20.6–59.6) per 100.000 inhabitants. Table 1 shows the incidence rates of vascular PAPS. We identified 47 patients with venous events during 2011–2015. 27/47 (57%) were tested for aPL, 4/27 (15%) positive. Regarding arterial events, 36 patients had stroke and 33/36 (92%) were tested for aPL, 4/33 (12%) positive. Finally, 64 patients with myocardial infarction (IMA): only 14/64 (22%) were tested for aPL, 2/14 (14%) positive. Table 1 Incidence rates of antiphospholipid antibody syndrome per 100.000 inhabitants in Valtrompia in adult population (18–49 years) between 2011 and 2015. The 95% confidence intervals (CIs) are reported in parenthesis.Abstract AB1287 – Figure 1 Conclusions Preliminary results of this population-based study showed that PAPS is a rare disease. A critical point emerged from this study is that aPL were not routinely tested in young subjects with vascular events, especially in patients with myocardial infarction. The study will be implemented by contacting patients who never tested for aPL during the hospital admission. Disclosure of Interest None declared


In weakest link models the failure of a single microscopic element of a brittle material causes the failure of an entire macroscopic specimen, just as a chain fails if one link fails. Pristine samples of glass, such as optical communications fiber, approach their ideal strength, and their brittle tensile failure has been descried by this model. The statistics of weakest link models are calculable in terms of the statistics of the individual links, which, unfortunately, are poorly known. Use of the skewness of the failure distribution may permit simultaneous determination of the statistics of the individual weak links and of their number density, which indicates their physical origin. However, the applicability of weakest link models to real materials remains unproven.


Polysubstituted pyridines have been prepared in fair yields by a one-step reaction of heteroarene 3-bromo-2,3-dimethoxy-5-(methoxymethyl)pyridine (I) and lithio alkyl- and lithio aryl-acetonitriles via heteroaryne generated from (I) by LDA in THF. Most lithio arylacetonitriles yield rearranged products by the tandem-addition rearrangement pathway and a 2:1 to 3:1 mixture of normal hetaryne products


This paper presented an arc-fault diagnosis based on fractal theory Grid fractal.According to the different variation of the normal operating current at any time and the slope of the arc-fault current,the method then determines the mutation point of the current or current waveform distortion point by calculating the relationship between the adjacent current slope,thus makes a diagnosis to the possible arc-fault in line.


Constrained by current sensing technology, depth camera only acquires a low-resolution depth image that does not meet actual requirements. To solve this problem, this paper take a divide-and-conquer strategy to synthesize a high-resolution depth image from a low-resolution range image under the guidance of a registered high-resolution color image. Initially, the depth image is divided into planar areas and edge regions. For different zones, we exploit different methods to interpolate the missing depths. At planar area, the linear interpolation method is employed to perform upsampling. At edge region, a segmentation-separation upsampling method is used to interpolate the missing values. Then the upsampling result are refined on the Depth CNN that is built in this paper. We conduct extensive experiments on the benchmark database and real world data with various upsampling rates to illustrate the upsampling ability of our method. The comparison with classical super-resolution algorithms demonstrates that our upsampling algorithm achieves the best quality with fewer artifacts and our depth CNN outperforms the most state-of-the-art methods in terms of qualitative and quantitative evaluations.


ABSTRACT This commentary seeks to stimulate discussion about grassroots resistance that has taken on conglomerates in the faceless and leaderless 2019 pro-democracy movement in Hong Kong. The scale, scope, and time span of these protests is unprecedented in the city and, at the time of writing, there is no sign they will soon abate. Behind eye-catching scenes of black-clad protesters filling the streets, a sea of light in assemblies, rounds and rounds of tear gas fired by police, people covered in blood, and burning shops, is an emerging economic resistance movement that aims to generate alternative political resources in an acutely imbalanced bargaining structure between protesters and the government.


The corrosion- wear performances of low chromium white cast iron and effects of copper and nickel on its corrosion-wear performances were studied by self-made corrosion-wear tester which cans real-time measure the corrosion potential of samples. The results show that the corrosion potential of low chromium white cast iron can be increased when copper and nickel were added into it. Its weightless can be decreased, i.e. the wear resistance will be increased during corrosion-wear test. The corrosion-wear mechanism of low chromium cast iron is exfoliation corrosion when the test slurry is faintly acid(pH=5), and the corrosion-wear mechanism is the combined action of wear and corrosion when the test slurry is alkalescent(pH=10).


Using data from this work and from the literature, the standard free-energy changes for reactions i and ii, AG,+(g) and AGo12(soln), are compared: B(g) + H+(g) ~2 BH+(g) (i); B(soln) + 12(soln) s B...12(soln) (ii). Bs are S(sp3) and N(sp2 and sp') n-donor bases (all compounds for which data sets are extensive and reliable), spanning a range of AGH+(g) of ca. 65 kcal-mol-I. Within families, AGH+(g) and AGol,(soln) are linearly related. Thus, a pattern of reactivity similar to that prevailing in the gas phase can be found in acid-base reactions in solution, provided charge dispersal through hydrogen bonding to the solvent is minimized.


Children afflicted with significant respiratory distress related to acute and chronic chest disease are representative of all that is important in medicine. They encounter distress, fear, and the possibility of imminent death. These children nonetheless have the prospect – with care, attention and advancing knowledge – of their situation being improved. Anesthesiologists, intensivists and pediatricians have, through a combination of experience, clinical trials and innovation, contributed much to alleviate the burdens of chronic respiratory failure in children. It was predominantly in the young after all, that widespread implementation of mechanical ventilation was initially employed, thereby laying the foundations for modern intensive care medicine. Mechanical ventilation however was not without its downside: barotrauma, subglottic stenosis and vocal cord injury. Indeed early reports of noninvasive ventilatory support signaled the beginnings of a major new direction. Compared with the traditional invasive ventilation, the availability of noninvasive support represented the attractive option for greater access (more therapy available to more patients) and less complexity (simpler machinery, easier application). In fact the study of noninvasive ventilation evolved in concert with investigations of the relationship between sleep and breathing. Observations during these studies revealed how sleep depresses central respiratory drive and reduces airway tone. Moreover, noninvasive ventilation offered new solutions to old problems, and effective therapies are now routinely available for a spectrum of conditions ranging from troublesome snoring to potentially lethal sleep apnea. Currently, there is extensive literature concerning application of noninvasive ventilation in adults with respiratory failure (1,2). In general, it is most effective in adults presenting with hypercapnic respiratory failure, but several studies have broadened the indications. For example, Antonelli et al. (3,4) have demonstrated that adults with acute hypoxemic respiratory failure may do better with noninvasive approaches. Indeed, of particular interest to anesthesiologists, a recent report of early application of noninvasive continuous positive airways pressure (CPAP) in high-risk patients with postoperative atelectasis demonstrated a lower incidence of reintubation postoperatively. The same study revealed a lower incidence of pneumonia and sepsis in patients managed with CPAP (5). Regrettably, acute application of noninvasive ventilation has disappointed; the use of the technique following intubation delays, but does not prevent reintubation (6). This is a salutary lesson in the determinants for successful extubation in critically ill patients. As reported by Piastra et al. (7), in this issue, we learn of ongoing advances in noninvasive ventilatory support as applied to children. The authors expand upon their previous reports in children with myopathies, examining the uses and limitations of facemask and helmet ventilatory support (8). The report prompts us to reflect on the principles and practice of ventilatory support in children with chronic neuromuscular disease. What are these principles and what is the practice? The principles of acute invasive ventilatory support in the setting of chronic neuromuscular disease of childhood have traditionally included some or all of the following: securing the airway, providing sufficient mechanical assistance to reduce the work Correspondence to: Brian P.

Business is an interpersonal and organizational activity that involves the process of selling, purchasing both goods and services with the aim of making a profit. But to get a large profit, it takes many partners who have a high desire to move forward. Information technology provides services for business people so that media information is available as a sign of obstacles. In addition it is necessary to do modeling where the process of communication between businesses running on information technology has a different profit from the business being run. Thus the union has the principle of kinship and has the principle of profitability divided by the amount of contribution given so that the creation of a model in electronic business (e-business) in the hope of having a family principle that is able to provide special profits for businesses other than the profits that run on certain businesses.


There exist two prominent accounts of how managers make sense of and take action in relation to strategic issues. The threat–opportunity (TO) and feasibility–urgency (FU) approaches primarily emphasize automatic/affective and active/deliberative strategic issue diagnosis processes, respectively. Current research, however, does not effectively integrate or fully explore the relationship between these two frameworks. We employ theory-building literature to develop a framework that highlights four distinct and increasingly integrative lenses through which such an exploration can be systematically carried out. Analyzing data from how firms reacted to the economic uncertainty of early 2003, the results of our study indicate that the FU approach is a better predictor of both intentions and actual responses than the TO approach. Our results also indicate that threat is positively related to urgency and negatively related to feasibility, while opportunity is positively related to feasibility and negatively related to urgency. Further, using the expectancy–instrumentality–valence (EIV) motivational theory as a framework, we factor analyze both TO and FU items, identifying three underlying constructs of favorability, urgency, and influence (which we dub FUI). FUI has a higher predictive efficacy than the TO approach alone. We highlight implications for theory building and research in the strategic issue diagnosis literature.

The 3-dimensional (3D) interaction between cells and extracellular matrix (ECM) constitutes a dynamic regulatory system for directing tissue formation and homeostasis, as well as regeneration in response to injury. As such, significant progress has been made in the field of tissue engineering to develop 3D hydrogels capable of promoting cell viability and many of these important ECM interactions. However, the spatial patterning of hydrogels in 3D, motivated by the microscale heterogeneity of native tissue architectures, has only recently been a focus. Here, we review efforts to date to engineer structurally and/or biochemically patterned 3D hydrogels to control cellular behavior for regenerative medicine applications. Such techniques can be separated into two categories: stereolithographic "bottom-up" methods that pattern structures during layer-by-layer fabrication and post-gelation techniques involving modification of a uniform, pre-formed hydrogel. Many techniques in each group are further compatible with cell encapsulation, providing a valuable set of models for studying cell-cell signaling or for the engineering of new tissues.

Abstract This study compares the personality, motivation and leadership background of 104 Israeli social entrepreneurs and 85 business entrepreneurs. Social entrepreneurs are higher in extraversion and openness to experience, lower in managerial personality characteristics, and more driven by ideology rather than by capital gains. Social entrepreneurs also have stronger early ideological and leadership training. Multiple regression analysis reveals that a relatively robust and persistent set of internal psychological drivers prompt a search for specific experiences that are related to leadership roles and social change orientations, including social entrepreneurship and the relevant leading experiences in adolescence and young adulthood.


In this paper,a continuous-time biquadratic filter using Current Controlled Conveyors (CCCⅡ) is proposed,which can be used in Hearing Aids and in other Analog Signal Processing applications. The proposed filter has the capability of amplifying as well attenuating the signal of any desired frequency band. This design can be easily implemented in MOS VLSI thereby allowing electronic tuning of the filter parameters. Theoretical analysis and computer simulation indicate that the proposed circuit is effective and feasible.


It is of great significance to describe the innovation track of emergency management digital research through metrology for better grasping the theoretical system and subject frontier, and promoting the practice of emergency management digital. In this paper, artificial intelligence (AI) papers published in the world from 2010 to 2019 in the SCI database of Web of Science are taken as the research object to explore the influence of countries in the field of AI research and the current hot areas, so as to provide data support and decision-making reference for AI policy making. It is found that in the process of the development of the digitalization of emergency management from scratch, a novel and complete research system has been formed, which takes the digitalization of emergency management technology as the core and takes the digitalization of emergency management organization, the digitalization of emergency management environment and the digitalization of emergency management objects as the foundation. Further studies have found that digital frontier including emergency management in large data, mobile Internet, Internet of things, technology innovation, and AI as the representative of volunteers to digital citizens in emergency management, digital and digital community, represented by the main body of innovation, and to no one digital dynamic emergency management and the digitization of emergency management as a representative of management innovation. Finally, the study concludes that the digital integration of emergency management consists of two parts: risk information and emergency response.


For the transfer of an excitation on a periodic linear chain with excitation-phonon interaction, the authors have determined quantitative limits for the ranges of three types of memory-function behaviour (coherent, incoherent and quasi-coherent) for microscopic input parameters and temperature. The dependence of transition rates on real microscopic quantities and temperature is calculated.


Aerodynamic noise control is important for various engineering applications, including automobiles. To develop effective control methods for the flow and sound of bluff bodies, flow past a cylinder is usually studied as a simplified problem. In this study, a passive control technique using surface protrusions was developed to suppress the aeolian tone generated by a two-dimensional laminar flow past a circular cylinder. Protrusions were created on the front and rear surfaces of the cylinder using an optimization approach based on the lattice Boltzmann and adjoint methods, allowing the optimization of complex geometries. The computational results revealed that a pair of protrusions on the front surface could stabilize the separated shear layers by fixing the separation points to their tips, whereas a pair of protrusions on the rear surface can stabilize the separated shear layers by interfering with the interaction between the top and bottom shear layers. Consequently, these shapes effectively suppressed the vortex shedding and aeolian tone while decreasing the mean drag. A shape with symmetrical protrusions on the front and rear surfaces reduced the aeolian tone by 3.6 dB.


In typical optical sensor setups for CO2 laser material processing scraper mirrors or beam selectors (ZnSe mirrors) are used to allow sensor positions which have a coaxial path for both the laser beam and the monitored visible or near- infrared signal. Calculations and experiments have shown a vital influence of the focusing element for the laser beam on the measured signal. Critical topics are the distance between focusing element and monitored process, as well as the dependence of focal length on wavelength.


The purpose of this study was to investigate EFL teachers' awareness and practices of vocabulary teaching strategies in EFL classes. The participants of the study were 16 teachers and 180 students at Debre Tabor secondary school, Woreta secondary school, and Tewodros II secondary school. Multiple instruments that included questionnaire, interviews, and observations were used to gather data. The findings indicated that grade 9 EFL teachers' understanding towards the principles and purposes of vocabulary teaching strategies were insufficient. Based on the findings, it was concluded that the EFL teachers didn't properly practice various strategies in their schools. Furthermore, the practices of vocabulary teaching strategies were not given sufficient attention at the schools of the study. Finally, it is recommended that teachers & students be given trainings on the strategies of vocabulary teaching, and the concerned bodies provide the availability of prepared materials for its effective utilization in schools.


The natural cytotoxic activity of yolk sac (YS) cells from 10‐day mouse embryos against YAC‐1 tumor targets was characterized for its sensitivity to modulation by a variety of factors. Experiments demonstrated the observed levels of tumor cell lysis to be unaffected by the strain of origin of the YS cells, trypsin pretreatment of the YS population, as well as a prior stimulation by environmental pathogens. Both the YS natural cytotoxic (YSNC) activity and the adult natural killer (NK) cell activity were found to be depressed when assayed in the presence of amniotic fluid. YS cells were tested for antibody‐dependent cell‐mediated cytotoxic activity, but were not found to generate significant levels of lysis.


The fluorescence of anthracene excited by x rays from a 600 keV pulsed source was investigated. An x‐ray dose of 7.6 × 1012 eV cm−3 produced a prompt fluorescence output of 1.4 × 1011 photons cm−3, as well as an intense delayed fluorescence. Analysis of the time dependence of the delayed fluorescence, based on the diffusion kinetics of triplet excitons in tracks, indicated that the above dose produced 7 × 1010 singlet excitons by direct excitation (S0→Sn transitions) and 2.7 × 1011 short‐lived ion pairs, of which 7 × 1010 recombined to form singlet excitons and 2 × 1011 recombined to form triplet excitons. In these calculations, the value of the triplet exciton diffusion coefficient was found to be (1 ± 0.5) × 10−4 cm2 sec−1.The fluorescence of anthracene excited by x rays from a 600 keV pulsed source was investigated.

Analytical expressions of the slope measurement errors is derived and the gain brought by our new Weighted Center of Gravity estimator is quantified.


Throughout the history of cryptography, hundreds of cryptosystems have been developed. The earliest ones, as well as many later ones, relied on the complete secrecy in transferring keys between the sender and recipient. These kinds of systems, called secret key cryptosystem, have just a single key which is used for both encryption and decryption; therefore, these systems are more frequently known as symmetric cryptosystems. In contrast to a symmetric cryptosystem, an asymmetric cryptosystem is associated with a pair of keys; therefore, not everything related to the cryptosystem needs to be kept secret. This kind of a cryptosystem is also called public-key cryptosystem. A public key cryptosystem consists of a public key, which is used for encryption, and a private key, used for decryption. Therefore, anybody can encrypt plaintext since the encryption key is available to everyone, but only the holders of the private key corresponding to the public key used for encryption can decrypt the ciphertext [2]. The first asymmetric cryptosystems appeared in 1970s to address the problem of key management in symmetric cryptography. In 1976, Whitfield Diffie and Martin Hellman published a key management scheme that was the predecessor to the first public-key cryptosystems; it later became known as the DiffieHellman Key Exchange Protocol. Later, several asymmetric cryptosystems were developed, including ElGamal, Rabin, and RSA cryptosystems ([2], [1]).


One of the harmful effects of cigarette smoking is back pain. Cessation of smoking improves the pathological changes in the disc that are caused by smoking. Education has a greater effect among higher socio economic groups in encouraging to quit. Financial pressures are known to have a greater effect on lower socio economic groups. Back pain sufferers on social benefits and who smoke are more likely to be in the lower socio economic group. Given the benefits of quitting smoking would it not be beneficial to provide an intense campaign among this select group to give up smoking or to face curtailment of social benefits?

The reliability and profitability of subjective assessment for the classing of Fine Wool Merinos was compared with objective measurement in the form of selection indices using CSIRO Fine Wool Project (FWP) data. Estimated heritability for classer grade using subjective assessment was 0.12. Classer grade was more strongly correlated with style, colour and body weight than correlations with objectively measured fleece traits. The repeatability between years of classer grade (0.34) was lower than that of greasy fleece weight (0.64) and mean fibre diameter (0.76). Average fleece value was estimated on a per bloodline basis and used to compare selection efficiency of a 12% index selection with classer grade.


An experimental investigation was made of the characteristics of a pulsed CF4 laser at high pump power densities. A radiation intensity of 0.5 MW/cm2 was obtained at a frequency of 615 cm−1 when the pump power conversion efficiency was 12%. Calculations are made of the laser parameters using steady-state and complete models. It is found that two-photon processes may play a decisive role in the lasing mechanism. The feasibility of using amplifiers to improve the radiation power in the 16μ range is determined.

An optical source that produces single-photon pulses on demand has potential applications in linear optics quantum computation, provided that stringent requirements on indistinguishability and collection efficiency of the generated photons are met. We show that these are conflicting requirements for anharmonic emitters that are incoherently pumped via reservoirs. As a model for a coherently pumped single photon source, we propose cavity-assisted spin-flip Raman transitions in a single electron charged quantum dot embedded in a microcavity. We demonstrate that using such a source, arbitrarily high collection efficiency and indistinguishability of the generated photons can be obtained simultaneously with increased cavity coupling. We analyze the role of errors that arise from distinguishability of the single-photon pulses in linear optics quantum gates by relating the gate fidelity to the strength of the two-photon interference dip in photon cross-correlation measurements. We find that performing controlled phase operations with error $l1\phantom{\rule{0.2em}{0ex}}%$ requires nanocavities with Purcell factors ${F}_{P}\ensuremath{\geqslant}40$ in the absence of dephasing, without necessitating the strong coupling limit.


Alumina-chromium cermet bodies containing 20 to 70 vol. % Cr were hot-pressed at 1400°-1470°C and 150kg/cm2 for 20-30 min., in argon atmosphere using graphite molds having a circular hole of 8mm in diameter, or a rectangular hole of 4×15mm.From the results of this study it was concluded that:(1) In hot pressing, increase in the chromium content decreased the press-temperature, for instance, 1400°-1430°C for 60 vol. % of chromium, being about 300°C lower than the hot-pressing temperature in hydrogen atomosphere (Table 1).(2) Measuring the hardness distribution along the center line of hot-pressed bodies whose hight to dia. ratio was 2:1 the method of pressing was studied, and the best result was obtained when the pressure was applied with a plunger moving downwards in a floating die. (Table 2 and Fig. 3).(3) The distribution of hardness in hot-pressed bodies of complex shape was studied with a result that there are some regions giving lower hardness values caused by the lack of the flowability of the mix, which suggests the necessity of three directional pressing (Photo. 2).(4) The transverse rupture strength of hot-pressed bodies of the size 4×4×15mm were 55-72kg/mm2 at room temperature.(5) The microstructure of hot-pressed bodies was characterized by the occurence of smaller corundum crystals of the order 1-3μ, and by the more rough boundaries between the alumina and chromium phase than those in the bodies sintered in hydrogen atmosphere. Continuous metallic phase was observed in the hot-pressed bodies containing more chromium than 60-70 vol. % (Photo. 3).(6) Fractures in the tension side of the specimens of bending rupture test passed through the crystals. of corundum, chromium as well as their phase boundary, and consequently, both chromium and corundum phases were appeared in the electron microphotographs (Photo. 4-5).

The paper presents trends of nitrogen management intensity changes. The comparative analysis of nitrogen management in the period 2002-2016 was performed at FADN regions of Poland level. It included comparisons of balances and efficiency of nitrogen utilization as well as rate and direction of nitrogen input and output in the agricultural production cycle. The structural and quantitative analysis of both sides of gross nitrogen balance provides information about the agricultural production as well as the direction and rate of changes . Although there was a visible, moderate intensification (A= type) of agricultural production in Poland, a significant differences between four regions of Poland were found. FADN region 785 (Pomorze i Mazury) had positive rating of agro-environmental aspects and nitrogen management. On the other hand, FADN region 790 (Wielkopolska i SSlask) was characterized by ineffective intensification of plant production (increased nitrogen inputs with low effect in nitrogen output).
