An engraved view of the 'Gothic Tower At Wimple', published anonymously in 1777, carries beneath it a four stanza verse which might easily be dismissed as frivolous doggerel, typical of the eighteenth-century vogue for Gothick poetry (Fig. 1).' Artless it may be, but this mock-elegy for a glorious medieval past does much to explain why ruinous architecture so appealed to the aristocrats and antiquaries of the age. The verse demonstrates a delight in the so-called 'Theory of Association', by which architecture could be invested with moral or political significance and linked with historical or imaginary events.'


The investigation found that there are many unscientific local taboo behaviors in the puerperal period such as the behaviors in parturient woman's diet,the health care,the daily activity,the dress and the environment.The occurrences of these behaviors are high.Special puerperal period health education should be offered to the pregnant woman and the family member to popularize the scientific knowledge of "the passing first month after childbirth",and to change the old conventional behaviors.


By considering the problems to be solved from a software engineering point of view, we will not only consider the feasibility provided by the mechanisms embedded in the platform we are defining, but also the economic1 aspects. This last point burns down to: how easy will it be to implement, deploy and manage complex distributed services in the application domains we are considering, i.e. firewall based security assessment, video on demand services, business process modeling and transactional workflow system applied to business to business electronic commerce, by using the mechanisms, methodologies and tools providing support to the approach(s) defined within C 3 DS.


We employ a new empirical approach based on dynamic threshold partial adjustment models to study the asymmetry in firms' adjustment towards their target leverage ratios. We examine several factors proxying for differential costs of adjustment that may lead to the heterogeneity in the speed with which firms adjust their capital structure. Using an unbalanced panel of UK firms, we find that firms having high dividend payments, large investment, high profitability, high growth opportunities, or a large deviation from their target leverage have slower speeds of adjustment than those with the opposite characteristics. We further observe a consistent pattern that firms move towards target leverage quickly when they are over-levered, possibly to avoid the large financial distress associated with having above-target leverage. Taken together, our results provide strong empirical support for the dynamic trade-off theory. JEL Classification: G32.


Poly(ethylene 2,6, naphthalene dicarboxilate), PEN, is very similar to poly(ethylene terephthalate), PET, in its chemical structure and was, therefore, expected to exhibit similar processing characteristics. We, however, observed a few problems during stretching of PEN, the most important of which was necking behavior at 145°C, which is between Tg (117°C) and Tcc (195°C). This is usually observed in PET only when it is stretched close to or below Tg. At temperatures between Tg and Tcc (cold crystallization temperature) PET stretches rather uniformly. The temperature window for film stretching appears to be rather wide, but our results indicate that this is not the case. Films stretched to high stretch ratios become uniform due to propagation and final disappearance of necks as a result of stress hardening. Our attempts at stretching these films at higher temperatures indicated that necking is eliminated, but so is stress induced crystallization, which causes stress hardening (unless high stretching rates are employed). The presence of stress hardening is essential for obtaining high quality, uniform films of these polymers. In addition, at high temperatures thermally activated crystallization which starts dominating the structure development, detrimentally affects the general appearance of the films. In brief, the PEN films we investigated have a narrower processing window than was anticipated based on their thermal behavior alone. At elevated temperatures the films are sensitive to the rate of stretching even more than typical PET processed at comparable conditions. The uniformity of the films depends on the stretch ratio, stretching mode, ratio(s) and rates and temperature. WAXS studies on the films indicate that the macromolecules packed into the low temperature crystal modification. In addition, WAXS pole figure studies suggest that naphthalene planes preferentially orient parallel to the film surface during biaxial stretching. The biaxially stretched films were observed to exhibit a bimodal chain orientation as evidenced by pole figure analysis of the (010) planes.


A new analytical model for the configuration of a four-high rolling mill stand is proposed in this article. Using the model, the dominant sources of stiffness in the fifth octave and the third octave models are identified. The assumptions made for the derivation of the model are that the work rolls are isotropic linear elastic, that there is no gap or separation between the work roll and the backup roll at all times. In addition, only the vertical interactions of the work roll and the roll-bite are considered. The nonlinear characteristics of this dynamic system are contributed from the contact area of the work roll and the backup roll. Analyses show that the natural frequency of the nonlinear analytical model matches the fifth octave rolling chatter, and the dominant parameters of the dynamic instability are characterized. The effects of inter-stand tensions, rolling speeds, friction between the work roll and the metal sheet roll-bite, and the thickness of the metal sheet on rolling chatter are discussed in the analysis of the dynamics of the rolling model.


Wearable tactile navigation displays may provide an alternative or complement to mobile visual navigation displays. Landmark information may provide a useful complement to directional information for navigation, however, there has been no reported use of landmark information in tactile navigation displays. We report a study that compared two tactile display techniques for landmark representation using one or two actuators respectively. The single-actuator technique generated different vibration patterns on a single actuator to represent different landmarks. The dual-actuator technique generated a single vibration pattern using two simultaneous actuators and different pairs of actuators around the body represented different landmarks. We compared the two techniques on four measures: distinguishability, learnability, short term memorability and user preference. Results showed that users performed equally well when either technique was used to represent landmarks alone. However, when landmark representations were presented together with directional signals, performance with the single-actuator technique was significantly reduced while performance with the dual-actuator technique remained unchanged.


The reactions of PtCl{sub 4}{sup 2{minus}} with oligoglycyl peptides in aqueous solution proceed by amine coordination followed by sequential deprotonation and coordination of available peptide nitrogens. Complexes of PtLCl{sub 3}{sup 2{minus}}, Pt(H{sub {minus}1}L)X{sub 2}{sup 2{minus}}, Pt(H{sub {minus}2}L)X{sup {minus}}, and Pt(H{sub {minus}3}G{sub 4}){sup 2{minus}} (where L = triglycine (G{sub 3}), triglycinamide (G{sub 3}a), or tetraglycine (G{sub 4}), X = Cl{sup {minus}} or OH{sup {minus}}, and H{sub {minus}n} designates the number of deprotonated-N(peptide) bonds) are characterized by use of {sup 195}Pt NMR spectroscopy. Several bis(peptide) complexes also are identified. Structural assignments are made on the basis of coupling constants with ({sup 15}N)peptides. The magnitude of the J{sub Pt-N} coupling constants are Pt-N{sup {minus}}(peptide) > Pt-N(amine) {approx} Pt-NH{sub 3} (N{sup {minus}} denotes the deprotonated peptide nitrogen); the trans influence on Pt-N(amine) or Pt-N{sup {minus}}(peptide) is N{sup {minus}}(peptide) >> OH{sup {minus}}, RNH{sub 2}, NH{sub 3} > Cl{sup {minus}}. The chemical shifts for {sup 195}Pt are determined primarily by the elements coordinated to platinum(II) and secondarily by their chemical form. Monodentate amine coordination by the oligopeptide or the formation of the first chelate ring with amine and N{sup {minus}}(peptide) coordination gives an upfield shift of 110 ppm relative to the signal fore the corresponding Pt(NH{submore » 3})X{sub 3}{sup {minus}} or cis-Pt(NH{sub 3}){sub 2}X{sub 2} complex. Two linked consecutive five-membered rings from peptide chelation cause an offsetting downfield shift of 120 ppm, and three linked consecutive five-membered chelates introduce an additional downfield shift of 250 ppm (relative to the coordination of one or two more NH{sub 3} molecules). 38 refs., 10 figs., 5 tabs.« less


Aging of the North American population has increased the incidence of osteoporosis causing concern to health care providers. This study tested the pharmacokinetics of two calcium sources and their relative effects on parathyroid hormone (PTH). Calcium amino acid chelate and calcium carbonate were studied. Fifteen healthy female subjects, ages 25 to 45, having 25(OH) D (vitamin D) levels between 50 nmol/L and 125 nmol/L and a BMI >;20 and ≤35 kg/m2were included. Subjects followed a low calcium diet 7 days prior to and during the clinic test period. Blood samples collected at pre‐dose, 30 minutes, 2, 4, 6, 9, and 12 hours post‐dose were assessed for serum calcium and parathyroid hormone. Subjects administered calcium amino acid chelate had 16.6% higher serum calcium 4 hours post‐dose compared to calcium carbonate. There were no significant differences in serum calcium AUC(0–12h), Cmax, and Tmax between groups. Subjects on calcium amino acid chelate had significantly lower parathyroid hormone levels compared to those on calcium carbonate (P=0.012). The significantly lower values of serum PTH at 4h for calcium amino acid chelate coincided with the maximum concentration of calcium reached in the serum for this formulation. Calcium amino acid chelate produced a significant suppression in serum PTH levels during the test period, suggesting that this formulation was more bioavailable than the calcium carbonate formulation. This study was sponsored by Biotron Laboratories, Inc.


This paper proposes a frequency reconfigurable antenna system designed for cognitive radio applications. The antenna structure consists of a sensing antenna and a frequency reconfigurable antenna system. The sensing antenna scans the channel to discover frequency bands while the reconfigurable section is tuning to communicate within these bands. A reconfigurable antenna consists of five different patches and there frequencies cover from 2.1 GHz to 10.6 GHz. The frequency agility is achieved via a rotational motion of the patch antennas. The rotation is controlled by a stepping motor mounted on the back of the antenna structure and the motor's rotational motion is controlled by MEMS switch connected to a microcontroller. A frequency reconfigurable antenna offers many advantages such as easy fabrication, suitability for installation and coverage spectrum UWB (Ultra Wideband).


Birth rate reached its lowest point in Hungary in 1962 with 12.9/1000. In 1965 it was 14.8/1000, still under the level required to ensure replacement of the population. In 1973, population policies were started to encourage a higher birth rate, such as state benefits or family allowances to numerous families. Still, in 1978 the birth rate was only 15.7/1000 and a further decrease is expected until 1982. Between 1958 and 1977 six surveys were conducted in Hungary on fertility and birth control. Abortion was legalized in 1956, mainly with the purpose of avoiding the health impairment caused by illegaly induced procedures. The number of abortions increased until 1969, and then decreased. Data show that abortion rate among married women decreased 50% during 1957-1978, while, during the same period, it more than doubled among unmarried women. In 1958 contraception was practiced by 21% of the female population, but the percentage had increased to 52% in 1977. The pill is now used by 1/5 of women between 17-49, and it is by far the most popular method of contraception, especially among younger women. A survey conducted in 1977 shows that 80% of women plan the number of children before getting married; 2 children is considered to be the ideal family size.


Summary The Burr distribution (Burr type XII), which yields a wide range of values of skewness and kurtosis, can be used to fit almost any given set of unimodal data. The Burr distribution has appeared in the literature under different names. The relationship between the Burr distribution and the various other distributions, namely, the Lomax, the Compound Weibull, the Weibull-Exponential, the logistic, the log logistic, the Weibull and the Kappa family of distributions is summarized. Also it is shown that the 'reciprocal Burr' distribution (Burr type III) covers a wider region in the (V,f fi2) plane and includes all the region covered by the Burr type XII distribution.


Akkermansia muciniphila  is an anaerobic species of gut microbiome that has been proposed as a new functional microbiota with probiotic properties. Recent research has shown the amazing abilities of probiotic bacteria,  A. muciniphila , which resides in most people's intestines. These bacteria affect the body if it increases or decreases abdominal fat. The presence of  A. muciniphila  has opened new ways for the use of this plentiful intestinal symbiont in next-generation therapeutic products, as well as targeting microbiota dynamics.  A. muciniphila  is particularly effective in increasing mucosal thickness and enhancing bowel barrier function. As a result, host metabolic markers improve. The host functions that are disrupted in various diseases with a particular focus on metabolic disorders in animals and humans. A specific protein in the outer membrane of  A. muciniphila  called Amuc-110 could in the future be a strong candidate for drug production. As a result, we suggest that microbes and our microbiology or gut microbiome knowledge could be a new source for future treatments. The objectives of this review are to summarize the data available on the distribution of  A. muciniphila  gut in health and disease, to provide insights into the environment and its role in the creation of microbial networks at the mucosal interface, as well as to discuss recent research on its role in regulation.


secondary to renal ischaemia hypertension is usually severe, and it is almost always accompanied by papilloedema. In primary aldosteronism, on the other hand, symptoms of hypertension are infrequent and papilloedema is very rare.5 Differences in the level of electrolytes in the serum may also help in diagnosis. In primary aldosteronism the level of potassium in the serum is usually in the range 2.0-3.5 mEq/l., but it may be as low as 1.4 mEq/1.,6 and the serum sodium is either normal or raised.5 In hyperaldosteronism due to renal ischaemia the serum potassium is also low, but figures below 2 mEq/l. have not been recorded, and the serum sodium is usually below normal. Unfortunately these simple criteria are not absolute, and often it is necessary to undertake renal arteriography or perirenal oxygen insufflation to try to demonstrate an adrenal tumour or a smaller kidney on one side. The hyperaldosteronism of renal-artery stenosis probably arises from the sequence: ischaemia of the kidney increases the secretion of renin ; the amount of angiotensin formed is increased and this leads to an increased secretion of aldosterone. Renin, through its conversion product angiotensin, has been shown to be a potent stimulator of the secretion of aldosterone.'-" The role of renin in renal hypertension is still in doubt, but raised levels of renin in the plasma are common in patients with renal-artery stenosis and hypertension, particularly when hypokalaemia is also present." One patient with renal-artery stenosis and secondary hyperaldosteronism who was recently studied by M. A. Barraclough and his colleagues was found to have a very high plasma-renin level. It fell to normal after the stenosis had been corrected, and the hypertension and the hyperaldosteronism were cured." In hyperaldosteronism arising from a primary abnormality of the adrenal the associated increase in body sodium might be expected to depress the secretion of renin, for the renin in the plasma falls when normal subjects increase their intake of sodium." J. W. Conn and his colleagues'4 measured the concentration of renin in the plasma in three subjects with primary aldosteronism, and were unable to find measurable amounts even during periods of sodium restriction. J. J. Brown and his co-workers,'5 though critical of Conn's assay method, have confirmed his findings. Conn1," however, finds that his method is sufficiently accurate for the task of proving suppressed renin activity in primary aldosteronism. Hence determinations of plasma renin will probably be useful in distinguishing between these two syndromes; unfortunately the assay methods are complex and are unlikely to become available in many centres. Polycythaemia vera has recently been described in a patient with stenosis of the renal artery."' The disappearance of polycythaemia immediately after nephrectomy suggested that the association was not fortuitous. Though the exact mechanism is obscure, renal-artery stenosis should be remembered together with the other renal causes of polycythaemia-namely, hypernephroma, hydronephrosis, and cystic renal disease. G. M. Berlyne and his colleagues"8 have recently described three patients with renal-artery stenosis and the nephrotic syndrome, and have reviewed other work on this association. There is no evidence that ischaemia of the kidney as such leads to proteinuria which is sufficient to deplete the plasma of albumin and produce oedema. Nevertheless renal ischaemia can lead to malignant hypertension or hypertensive cardiac failure, and either of these complications may cause the nephrotic syndrome. In one of Berlyne's patients, a girl of 13 years, stenosis of a renal artery was a feature of generalized atheroma which resulted from a long-standing nephrotic syndrome with hypercholesterolaemia. The other two patients probably had a nephrotic syndrome as a result of malignant hypertension caused by renal ischaemia. Some caution is necessary in attributing features of a patient's illness to stenosis of the renal artery, whether the alleged complication is hypertension, hyperaldosteronism, or nephrotic syndrome. It is reasonable to postulate a cause-andeffect relationship if the syndrome disappears permanently after successful arterial reconstruction or nephrectomy. But otherwise a causal relationship cannot be proved, and the association may be fortuitous. Recent surveys'9 20 have made it clear that renal-artery stenosis, often bilateral, is a common finding at routine necropsies of patients who have been known to have a normal blood-pressure, particularly in those over 60 years of age.

ABSTRACT Manufacture of modern aircraft components involve production of high value near net-shape carbon fiber reinforced polymer (CFRP) parts, which requires drilling holes for rivets and bolts at acute inclinations. The study explores the surface morphology of the inclined holes (30 ͦ, 60 ͦ, and 90 ͦ) drilled in CFRP under cryogenic cooling using coated carbide tools. Inclined hole drilling performance was measured using machining forces, surface finish, and bore integrity. It has been shown that cryogenic machining of acutely inclined small diameter holes generated at least 40% higher thrust forces compared to dry cutting. Surface quality under cryogenic was enhanced than dry cutting with reduced matrix transverse cracking that helped suppress the fiber debonding and pull out. This mechanism also aids to minimize stress concentration regions along matrix/fiber interfaces due to promotion of fracture mode II in-plane sliding shear of carbon fibers and reduction of fracture mode III out of plane peel-up and push-down interlaminar delamination. Effect of tool coating on bore surface integrity showed that double coat TiN tool with a point angle of 140 ͦ generated at least 40% lower thrust forces than Physical Vapor Deposition (PVD)-coated multilayer TiAlN flat bottom drill during cryogenic-assisted drilling.


Abstract In the early years of the twentieth century Paul Vidal de la Blache and his disciples were actively promoting geography as a distinct science and its propagation in schools and universities in France. A large collection of letters received by Albert Demangeon between 1904 and 1917 casts light on the social dynamics of the proteges of Vidal who produced the first generation of French regional monographs. Correspondents emphasised the challenge of writing a substantial doctoral thesis, often on a part-time basis, and expressed anxiety to secure a university position. The power of Vidal and of Lucien Gallois in shaping the scholarly trajectories of Demangeon and his contemporaries, and involving them in the Geographie Universelle , emerges clearly. Letters received during World War I conveyed not only tragic accounts of mutilation and death among geographers but also offered remarkable examples of academic and personal optimism. Through their teaching and publications Demangeon and de Martonne would ensure that Vidalian orthodoxy influenced the practice of geography in French schools and in most French universities.


INTRODUCTION AND OBJECTIVE: Urologic surgeries have been previously identified as having high rates of readmission compared to other surgeries. This study aims to identify risk factors leading to presentation to the emergency department (ED) following urologic outpatient surgery. METHODS: We examined all outpatient surgeries performed by urology, general surgery, thoracic surgery, and gynecology occurring at three hospitals within The Ottawa Hospital system between April 1, 2008, and February 28, 2018. We captured all ED visits within 90 days of the outpatient procedure. Surgical characteristics included hospital campus, procedure end time, and day/month/year of procedure. Patient characteristics assessed included age, sex, marital status, presence of primary care provider, socioeconomic status (SES), American Society of Anesthesiologists (ASA) score, and Elixhauser comorbidity index. RESULTS: 38,377 outpatient procedures were performed by the four services assessed over our time period. 5641 ED visits within 90 days were identified. Urological procedures accounted for 47.5% (n [2681) of the patients returning to the ED, representing a 16.2% rate of return to the emergency room following urologic day surgery. Furthermore, urologic patients were more likely to have several visits to the emergency room within 90 days compared to other surgical services (p<0.05). Univariable analyses of individual variables found that increased age, low SES, unmarried status were all associated with higher rates of ED visits (p<0.05). The median ER visit day postprocedure ranged from 5-17 depending on procedure type. Of the noted reasons for emergency presentation, the top 5 causes were directly related to urology with retention (11% of visits), and hematuria (10% of visits) being the most common. Of urological day surgery procedures ureteroscopy (Relative Risk (RR) 3.69, 95% CI 2.17,6.29), Greenlight Laser Photoselective Vaporization of the prostate (RR 3.6, 95% CI 2.05, 6.34), and ureteric stent insertion (RR 3.83, 95% CI 2.17, 6.76) had the highest rates of return to emergency in 90 days on multivariate analysis. CONCLUSIONS: ED visits following urologic outpatient procedures are common. This study identifies risk factors to identify patients that may benefit from additional education or support after outpatient urologic surgery to reduce ED care needs.


The combination of genomic and proteomic analyses is a useful tool for the study of novel Bacillus thuringiensis (Bt) strains, as these approaches allow the accurate identification of pesticidal proteins and virulence factors produced. Here, we isolated and evaluated the potential of a novel Neotropical Bt strain (TOD651) for controlling larvae of Aedes aegypti and Culex quinquefasciatus mosquitoes. Aiming for the full comprehension of the TOD651 larvicidal potential, we further evaluated the whole TOD651 genome and conducted the proteomic analysis of the TOD651 spore–crystal mixtures. Our results showed that Bt TOD651 similarly killed both A. aegypti (0.011 µg/mL) and C. quinquefasciatus (0.023 µg/mL) larvae, exhibiting similar potency to the commercial Bt strain. The genome sequence revealed that Bt TOD651 harbors cry11Aa3, cry10Aa4, cry4Aa4, cry4Ba5, cyt1Aa5, cyt1Ca1, cyt2Ba13, mpp60Aa3, and mpp60Ba3. The proteomic analysis revealed no expression of Mpp60Aa3, while all the other pesticidal proteins were expressed (Cry4Ba5 was more abundant than Cyt1Aa5). The expression of the Mppe showed the major proportions between proteases. The virulent factor neutral protease B and spore coat proteins were also expressed. The expression of relevant pesticidal proteins (e.g., Cry, Cyt, Mpp, and other pathogenic factors), whose actions can occur in a synergic relation, indicates that the biocontrol using Bt TOD651 may contribute to delaying the selection of resistant individuals.


Using new methods which perform 3H-thymidine autoradiography and AChE histochemistry on the same sections, the interrelationship among loss of proliferating ability, morphological development and increase of AChE activity during the course of differentiation of the neural tube cells were investigated in early chick embryos. The neural tube wall consisted of four kinds of cells: (1) AChE negative spindle shaped cells, (2) weakly positive spindle shaped cells showing AChE activity in the cisternae of the nuclear envelope and in a few short profiles of r-ER, (3) moderately positive spindle shaped cells showing AChE activity in the cisternae of the nuclear envelope and in a moderate number of r-ER profiles and (4) intensely positive large round cells showing AChE activity in the cisternae of the nuclear envelope and in a large number of r-ER profiles. Nuclei of the former three kinds of cells slet located in the ependymal layer, while the AChE intensely positive cells were in the mantle layer. The AChE negative and weakly positive cells were capable of proliferation and were regarded as undifferentiated neuroepithelial cells. The AChE moderately positive and intensely positive cells were, in contrast, no longer capable of proliferation and were regarded as neurons, especially the former as newly formed neurons. These findings indicate that the r-ER increases rapidly in number and in volume in newly formed neurons, soon after their final cell division, and that AChE activity increases in the neurons parallel to the development of the r-ER.


Techniques based on continued fractions to numerically compute the spectrum of the quantum Rabi model are reviewed. They are of two essentially different types. In the first case, the spectral condition is implemented using a representation in the infinite-dimensional Bargmann space of analytic functions. This approach is shown to approximate the correct spectrum of the full model if the continued fraction is truncated at sufficiently high order. In the second case, one considers the limit of a sequence of models defined in finite-dimensional state spaces. In contrast to the first, the second approach is ambiguous and can be justified only through recourse to the analyticity argument from the first method.


For three years 'Pink Lady®' apples were picked, at different stages of maturity (early, commercial and late harvest), ripened immediately at 20°C or stored in air at 0°C for 60, 120 and 180 days and kept at 20°C after removal from storage. The best storability and quality were attained after 60-120 days of storage with fruit harvested with the following maturity indices: light green-yellow ground colour (L* 69÷71; a* -9 ÷ -11; b* 40÷43), firmness 7.5÷8 kg f ; starch degradation 2.8-3.2 (scale 1-5), SSC 15% and titratable acidity 1-1.3 meq/10 ml. Internal browning seemed to be the main postharvest disorder of 'Pink Lady' apples. The incidence of this disorder, observed in the 2 nd and 3 rd year of experimentation, increased with the stage of maturity at harvest and the period of storage. Superficial scald was high (after 120-180 days of storage) only in fruit harvested too early. The susceptibility to fungal diseases increased with the period of storage. Sourness, vegetative aroma and chewiness, which characterised the fruit at harvest, decreased after 60-120 days of storage and during ripening at 20°C, leading to a more balanced fruit flavour and less hard texture. Fruit quality declined after 180 days of storage, due to loss of juiciness, crispness and fruitiness and increase in mealiness. Texture and flavour attributes of 'Pink Lady' apples with values lower than 6 kg f for firmness, 15% for SSC and 0.7 meq/10 ml for titratable acidity were not appreciated by a trained panel. 'Pink Lady' apples seemed to be suitable to 7-14 days of shelf-life at 20°C.

This article is ahout new methods of data processing at using Doppler-polarimetric characteristics of wave reflected from scatterers in rain. New characteristics of turbulence are considered, such as differential Doppler velocity, the inclination angle tangent of the differential reflectivity, and others. Data processing algorithms are developed. Comparison of math models with measured data are done. I. INTRODUCTION Meteorological conditions always essentially influence the operation of aviation transport, especially safety, regularity and comfort of flight. They influence economic parameters of air companies and aeronautics as a whole. The intensity and quantity of aircraft in intemational traces increase stably. That is why the problem of flight safety arises as especially important. The modem plane flies along few thousand kilometers from departure point to arrival point. The flight may occur in difficult meteorological conditions. This factor is the main in aviation crashes; more than 45% of aviation accidents happen under the difficult meteorological conditions. That is why any new possibility to make prevention of severe weather during the flight is very urgent. This paper is devoted to processing new Doppler-polarimetric characteristics. These characteristics were theoretically considered in (6). Some comparison of measured parameters with the theory is done. We hope that new approach that is considered in this paper finally will lead to increase the reliability of revealing dangerous weather phenomenon such as shower rain, snow, turbulence, and others,

Magnetic field measurements demonstrate that Saturn's internally generated magnetic field has an extremely small dipole tilt. The nearly‐perfect axisymmetry of Saturn's dipole is troubling because of Cowling's theorem which states that an axisymmetric magnetic field cannot be maintained by a dynamo. A possible mechanism to axisymmetrize the observed field involves differential rotation in a stably‐stratified electrically conducting layer surrounding the dynamo. Here we use numerical dynamo models to study the axisymmetrizing effects of stably stratified layers surrounding the dynamo. We find that a thin stably‐stratified layer which undergoes differential rotation due to thermal winds as a result of pole to equator temperature differences can produce a more axisymmetrized field. Surprisingly, we find that the direction of the zonal flows and their equatorial symmetry is a crucial factor for magnetic field axisymmetry since some zonal flows act to destabilize the dynamo producing non‐axisymmetric fields.


The provision of appropriate special education services to Mexican, immigrant children and their families who live in rural border areas of the United States begins with an understanding of the educational system in Mexico. A brief history and overview of the types of special education programs that are currently being administered in Mexico are provided. Additionally, the personal perspectives of two administrators who oversee programs in rural areas neighboring Ciudad Juarez are highlighted. Using in-depth interviewing to gain insight into the personal and professional experiences of these two professionals, emergent themes concerning special education in rural areas of Mexico are identified and discussed.


Big Data Analytics is one of the most cutting edge technology in the world. Big Data Analytics will provide data management to store, process and analyze the huge amount of data. Agricultural is one of the domains that assuring big data analytics used to make a change in the field. With the consistent enhancements of the peoples living lifestyle, step by step peoples concentrate on the demand of perishable agricultural products. However, the periodic eruption of food quality and safety issues affected the concern of the end-users. To enrich the distribution performance of agricultural product logistics and to provide the freshness, quality, and safety of the agricultural products has become a thread of the current agricultural domain. Big Data Analytics in Agricultural Products Logistics has an essential prospect of optimizing the distribution path of products, prediction of product demands in the market, traceability of the products, analyzing customer feedbacks and increasing overall performance of logistics in agriculture. This paper investigates the key challenges, methods used, technologies used, algorithms for distribution of products and future of Big Data Analytics in agro-logistics.


The residual supersymmetry and classical stability are investigated for the Kaluza-Klein solutions CP/sup 3/, CP/sup 2/ x S/sup 2/, S/sup 4/ x S/sup 2/, S/sup 2/ x S/sup 2/ x S/sup 2/ of N = 2 ten-dimensional nonchiral supergravity. It is shown that only the CP/sup 3/ solution possesses a residual (N = 6) supersymmetry. The solutions are then examined for scalar modes violating the Breitenlohner-Freedman stability criterion. It is shown that CP/sup 3/, CP/sup 2/ x S/sup 2/, and S/sup 4/ x S/sup 2/ may be stable against such modes.

Analysis of the spectra due to both the species has been carried out. Possible non-planar distortions at the nitrogen atom for the trans species have been computed using the derived dipolar couplings and the available structural data.


Vector control principles enable independent flux and torque control of an AC machine by means of only two stator d-q axis current components. This means that in AC machines with a phase number greater than three there exist additional degrees of freedom, which are nowadays used to enhance the overall torque production of a multi-phase machine through injection of higher stator current harmonics. However, these additional degrees of freedom can be used to control other machines independently within a multi-motor drive system. To do so, it is necessary to connect in series stator windings of all the multi-phase machines, with an appropriate phase transposition. A vector control algorithm is then applied to each machine separately, total inverter phase current references are created by summation of individual machine phase current references, and supply to the stator windings of the multi-machine set is provided from a single current controlled voltage source inverter (VSI). The concept is introduced in the paper using the general theory of electrical machines, and all the possible situations that may arise for an even number of phases are examined. Although an induction motor drive is considered throughout, the concept is equally applicable to all AC machines with sinusoidal stator and rotor flux distribution. Its main advantage is the potential for saving in the number of inverter legs, compared to an equivalent 3-phase motor drive system. The saving depends on the number of phases and, for an even phase number, comes into existence when the number of phases is 8. Various even phase numbers are considered in detail and appropriate connection diagrams are given. Verification of the proposed multi-phase multi-motor drive is provided by simulation of a 10-phase 4-motor system.


Aims: To study the prevalence of anemia among rural school children of Rajasthan. Study Design: A prospective cross sectional study was conducted in 8 government schools in tribal villages of Sirohi district over a period of 6 months. 1462 school children between 5 to15 years of age were clinically examined. Hemoglobin estimation was done using cynmethemoglobin method and peripheral blood smear were also examined. Anemia was diagnosed according to the WHO standard for the given age and sex. Materials and Methods: Hemoglobin estimation was done using cynmethemoglobin method. Peripheral blood film was prepared and stained by Leishman's stain using standard technique. Peripheral smear was examined by Pathologist to know the type of anemia and eosinophilia. Results: Overall prevalence of anemia was 83.6%. Girls had a higher prevalence of anemia than boys except at 10 years of age. Menarcheal age group girls (11 to15 years) were more anemic than boys and lesser age group girls (<11 years). The commonest blood smear picture was microcytic hypochromic (56.4%). Eosinophilia was observed in 21.6% children. Conclusion: There is high prevalence of anemia in rural school children of this part of the country. Girls were at higher risk of developing anemia. Dietary modification, improvement in hygiene and awareness are the key strategies recommended for prevention.


It is with great interest that we read the crosstalk on the proposed roles that changes in protein synthesis and protein degradation play in disuse skeletal muscle atrophy (Phillips & McGlory, 2014; Reid et al. 2014). However, rather than adopting an 'either/or' position on this topic, we believe that a more integrated standpoint is warranted. For example, recent evidence suggests that cells/tissues can simultaneously coordinate changes in both protein synthesis and protein degradation, including in skeletal muscle (Baehr et al. 2014; Zhang et al. 2014). Moreover, recent evidence suggests that, under certain conditions, an increase in protein degradation could lead to a decrease in protein synthesis. For instance, the eukaryotic initiation factor subunit 3f (eIF3f), which plays a crucial role in protein synthesis, is targeted for degradation by the E3 ligase atrogin-1, and preventing the atrogin-1-induced polyubiquitination of eIF3f provides protection against starvation-induced muscle atrophy (Csibi et al. 2009, 2010). Similarly, myostatin-induced myotube atrophy is not only associated with an increase in the expression of components of the ubiquitin proteasome system, but also an increase in the degradation of various translation initiation and elongation factors, ribosomal proteins, and a decrease in the rate of protein synthesis (Lokireddy et al. 2011, 2012). While these data are derived from cell culture and animal models, we must consider the possibility that similar mechanisms may also operate in human models of disuse atrophy, whereby an increase in proteolysis could play a significant role in the decrease in protein synthesis.


with its various elements. Therefore, it is not surprising that the great link between Law and Political Science was due to Constitutional Law and the General Theory of the State. When today we study the configuration of the State, we pay attention not only to administrative, judicial and legislative institutions, but also to the legal and political status that must be observed by the State and its governors. Thus, in today's democratic States, Law and Politics intersect in different ways. States, based on constitutional precepts, rest on their legitimacy and legality, on these precepts that contain, in turn, a double character: legal and political. Political Science and Law researchers and, desirably, from other areas of Social Sciences and even from other scientific areas, have the current challenge, to place their areas of study, on investigative platforms, which allow the development of these areas in multidisciplinary, interdisciplinary and transdisciplinary models.

Different degree of germination could increase damaged starch level hence effect on degree of polymerization of starch. Heat moisture treatment (HMT) of germinated paddy rice with appropriated chain length could improve crystalline perfection of starch. Slowly digestible starch (SDS) is digested slowly but completely in human's small intestine. It could stabilize glucose metabolism, diabetes management, mental performance, and satiety. Paddy rice (Pathumthani 1 and Riceberry cultivars) was germinated at 30 "C for 24, 36, 48, 60 h to initiate damage starch content by amylolytic enzyme. Pasting properties and gelatinization properties were found to exceedingly decrease. After germination, rapidly digestible starch (RDS) was increase substantially (60.9-66.4%) comparing to normal cooked rice (39.4-42.3%). However, the slowly digestible starch (SDS) and resistant starch (RS) of the cooked germinate rice were rapidly decreased. In order to benefit both blood glucose regulation and GABA content of germinated rice, Heat moisture treatment (HMT) was applied after paddy's germination at 90"C for 1h. Result showed that RDS of HMT germinated rice was lowering to 40.2-40.8%. Its SDS and RS increased to 42.1-43.6% and 7.6.-7.7% respectively comparing to germinate rice (24.9-26.9 and 2.5-2.8 for SDS and RS respectively).


Background: Threatening teachers increases their stress and impairs their emotional well-being. There are many reasons for violence against teachers. Threatening someone is considered as physical aggression. Aggression is any behavior intended to harm another person who wishes to avoid such harm High rates of aggression were reported recently in Iraq, especially after wars. Objectives: To estimate the prevalence of students' aggressive act and associated factors towards teachers in secondary schools in an under-privileged residential area in Baghdad. Methodology: A cross-sectional study was carried out in Al-Sadr city in Baghdad. A total of 720 adolescent secondary schools students from both genders were included in the study. They were selected by multistage random sampling. Their age ranged from 13-21 years. Data was collected from 1st of February 2019 to 30th of April 2019 through a self-administrated questionnaire (Aggression-Problem Behavior Frequency Scale). Results: The mean age of participants was 16.2±2.04 years. Of all participants, 84.3% were assessed to be aggressive. There was a significant difference between aggressive acts (threatening a teacher) and gender, school type, grades, history of absence from school, unemployed mother, and living with one parent (P=0.038, P=0.009, P<0.001,p= 0.02 and p=0.018,P<0.001, respectively). Among male students 10% reported that they threatened a teacher. Conclusion: the prevalence of aggressive acts towards teachers in secondary schools in an underprivileged residential area in Baghdad was high. Threatening a teacher was dominant among male students, secondary schools, grades, students with history of absence from school, unemployed mother, and living with one parent.


The purpose of this Master Thesis is to study the production of chlorine using saltwater which is the product of an existing desalination plant at Episkopi of Limassol.

Keywords: desalination, brine, chlorine, desalination methods, brine disposal technologies, chlorine production methods.


Abstract Objective The abstract Objective of this study is to investigate the cast-effectiveness of our new management model: Emergency consultation-observation room-ambulatory care.Methods one hundred selected CAP cases were randomly divided into 2 subgroups. One group was managed by the new model while another managed by the old method cemergency consultation-inpatient adminsion.Data of the two 2 subgroups:mortality, resolution of morbidity (=5 days), length of hospital stay, adverse events and treatment cost were compared. Results There were no significant differences in mortality, resolution rate of morbidity (=5 days) between Groups A and B(P0.05).But there were significant differences in length of hospital stay, adverse events and treatment cost between the 2 subgroups (P0.05) .Conclusion Early change to oral antibiotics not only can reduce the length of hospital stay, but also cut down the adverse reactions due to the long course of intravenous antibiotic usage. By this model we can reduce the cost of treatment and improve the compliance of patients.


Coal mining and coal combustion release environmental contaminants which stay at emission sites for many decades. The paper reports total Se and heavy metals (As, Cd, Cu, Cr, Hg, Pb, Sr, U, V, and Zn) in lettuce, potato, and tissues (liver, kidney, heart, and muscle) of three non-migratory bird species (pigeon, jay, and black coot) from a Rasa Bay area (North Adriatic, Croatia). They have presumably been exposed to elevated Se and metal levels in garden soil, surface water, and aquatic sediment contaminated with superhigh-organic-sulphur (SHOS) Rasa coal, highly enriched in S, Se, V, and U. Results point at selenium contamination of stream water (up to 78 µg/L total Se in a non-filtered sample), which is well above the Croatian regulatory threshold of 10 µg/L total Se. The stream drains a site of the former coal-separation unit, and an associated bottom sediment contains up to 10.8 mg/kg total Se, which is also above the safe level of 0.60 mg/kg total Se. Moreover, values of Mo, U, V, and Sr, elements commonly elevated in SHOS coal varieties, were also increased in majority of water samples as well as in analysed vegetables, soil, and aquatic sediments. Although Cu, Zn, Pb, and V were slightly increased in liver samples of birds, more in black coot than the other two birds, selenium values were found to be adequate for their normal growth. The fact that Se can be environmentally hazardous and toxic to life, even in small doses, warrants further research on this topic.

The separation of the latter from the former is suggested in this paper. By using computer doing the experiments it can increase experiment efficiency, share resources and reduce education cost.


Background  Chronic graft‐versus‐host disease (cGVHD) is a major complication of allogeneic bone marrow transplantation. Extracorporeal photopheresis (ECP) has recently been introduced as an alternative treatment for cases of cGVHD refractory to conventional immunosuppressive treatment, but its mechanism of action is not yet clear.


The lung is the most common metastatic site for all extrapulmonary malignancies except those arising in the portal watershed (1). Pulmonary metastases are found in 30% of autopsy-confirmed fatal neoplasms (2, 3). Up to 20% of patients who die with pulmonary metastases have no other sites of metastasis (3, 4). Pulmonary metastases represent the first recurrence in 50 to 60% of patients with some histologic tumor types, for example, osteogenic and adult soft-tissue sarcomas (5–7). Chemotherapy and radiotherapy for metastatic pulmonary disease is usually palliative, but in such tumors as osteogenic sarcoma and carcinoma of the testes adjuvant combination therapy has reduced the frequency of pulmonary metastases (8). Surgical resection of pulmonary metastases in some selected cases may be the only curative therapy (9–11). However, there have been no prospective randomized studies of pulmonary metastasectomy, and, therefore, it is usually unclear in specific cases whether the procedure will prolong survival or...


IT IS OUR VIEW that labeled directed graph data models (simple, nested, or hypergraphs) can naturally and usefully capture a wide variety of biological data and queries. We believe that development of general purpose graph data management systems (GDMSs) could become major platforms for development of a wide variety of bioinformatics database systems spanning applications from DNA sequences, chemical structure graphs, to contact graphs and biopathways. The use of a common data model and query language across numerous biological applications is very attractive from both a development and user standpoint. Considerable research and development effort are still required to extend current systems to meet modern requirements.

The cyclotron resonant frequencies of an exciton in a GaAs/Ga1-xAlxAs quantum-well structure have been studied. The results show that the cyclotron resonant frequency omega(c)* is lower than omega(LO) as a result of the electron-hole Coulomb interaction, and omega(c)* is a function of the quantum-well width, and does not exhibit ''pinning'' at a frequency near that of the TO phonons.


The place held by the Heart Sutra in Mahayana Buddhism parallels in some important ways that of the Gospel of John in Christianity. Each is foundational and central to its tradition. Each demands the practitioner's transformation through prayer and meditation. And, although the approach to deep and abiding human experience that is found in the Heart Sutra is quite different from that expressed in John's gospel, there is a resonance between the Sutra's emptying of every vestige of self-identity and John's call for a radical reconfiguration of consciousness. In this book, a Christian theologian reads the Heart Sutra, allowing its teaching on emptiness of self to percolate through his understanding of the central teachings of the Christian tradition ' incarnation and trinit y ' as these are disclosed in the Gospel of John.


If other Nobel Prize winners express their thanks for this high honour at this juncture by recounting the history of their discovery they are able to report how, at the outset, they envisaged a high, but nevertheless attainable, objective and how they strove toward that objective by many paths, most of which proved initially to be false and how then, after many years of protracted endeavour, they finally achieved their objective. In my eyes the credit to which they are entitled increases in direct proportion to the magnitude of the difficulties which they finally surmounted. By comparison, what I have to say here differs somewhat from those examples. There is no doubt that I, also, had long been aware of the problem, i.e. producing X-ray interferences, before the inherent difficulties had finally been surmounted. But I never believed that it would be my personal good fortune to make a contribution in that direction, and it was for that reason that I did not concern myself unduly in that respect until suddenly I perceived the way which subsequently proved to be the shortest path to success. I am not, therefore, able to recount many details in connection with my personal preparatory work, so I shall confine my comments to explaining the combination of scientific and personal circumstances from which the idea first arose.


Friction testing of microfibre arrays is typically conducted under displacement boundary conditions. For example, after the application of a compressive preload, the translation stage is fixed in the vertical direction while a shear displacement is applied by translating the stage laterally. A nonlinear rod model is used to compute the normal and shear forces acting on a typical microfibre during such a test. The normal load acting on a typical fibre is found to switch from compression to tension as the shear displacement increases. The critical shear force to detach a fibre is found to depend linearly on the compressive preload. The fibre is also found to become more stable as it is sheared, hence it never buckles. On the other hand, instead of fixing the vertical displacement, when a fibre is subjected to constant normal load, it becomes unstable upon shearing. We show that the buckling load (the applied normal load to make a fibre unstable) of a microfibril is reduced by the application of a shear displacement.


"My UNiTE to End Violence against Women campaign , and the Network of Men Leaders I launched last year, have generated welcome momentum and engagement. The word is spreading: violence against women and girls has no place in any society, and impunity for perpetrators must no longer be tolerated. On this International Day, I urge all – Governments, civil society, the corporate sector, individuals – to take responsibility for eradicating violence against women and girls."

A series of novel substituted 2-pyrimidylbenzothiazoles incorporating either sulfonamide moieties or the amino group at C2 of the pyrimidine ring were synthesized and evaluated for its antiviral potency. The novel synthesis of the ring system was carried out by reacting guanidine or N-arylsulfonated guanidine with different derivatives of ylidene benzothiazole based on Michael addition pathways. The antiviral activity of the newly synthesized compounds was examined by a plaque reduction assay against HSV-1, CBV4, HAV HM 175, HCVcc genotype 4 viruses, and HAdV7. In the case of HSV-1, it was determined that 5 out of the 21 synthesized compounds exhibited superior viral reduction in the range of 70–90% with significant IC50, CC50, and SI values as compared with acyclovir. In the case of CBV4, nine compounds have shown more than 50% reduction. Comparable results were obtained for seven of these synthesized compounds when evaluated against HAV with only a couple of them showing 50% reduction or more against HCVcc genotype 4. Remarkably, one compound, 9a, has shown broad action against all five examined viruses, rendering it as potentially an effective antiviral agent. The five potent compounds 9a, 9b, 14b, 14g, and 14h against HSV-1 have also presented inhibitory activity against the Hsp90α protein with IC50 in the range of 4.87–10.47 μg/mL. Interestingly, a combination of the potent synthesized compounds with acyclovir led to IC50 values lower than that of acyclovir alone. The potent compounds 9a, 9b, 14b, 14g, and 14h were also docked inside the active site of Hsp90α to assess the interaction pattern between the tested compounds and the active site of the protein.


IntroductionThe role of education has been pictured as a double-edged sword. On one hand, education increases those students' cultural capital who are able to benefit from education in any case. On the other hand, education feeds the exclusion of those students with weaker social backgrounds (Whitty, 2001). This study contributes to the discussion by focusing on experiences of school dropouts who became young prisoners.According to research (e.g., Dunne & Gazeley, 2008; Wardle, Robb, & Johnson, 2002; Gazeley & Dunne, 2007), equal education opportunities do not guarantee equality or equal treatment for all at school. Based on this viewpoint, school activities support those who represent the middle-class. Students with middle-class or upper-class backgrounds receive the positive benefits of schooling, while students with lower social statuses are left in the wilderness. They rarely succeed and receive no appreciation from others, and therefore, they develop subcultures to compensate for their feelings of inferiority and to gain experiences of success. One of the young prisoners interviewed in this study explained it as follows:We had our own group to hang out. It consisted of all dudes [in the small group teaching] because we were those tough guys there, and no one else wanted to do anything with us, nor do they want even today...So, we enjoyed our own group; what can you do?These kinds of sub-cultures opposing the school can manifest themselves as disturbing behaviors, ignorance of school tasks, isolation, absence, and, later on, as dropouts (e.g., Chen, Voisin, & Jacobson, 2016; Hong et al., 2014; Tapia, 2011). One extreme consequence of exclusion from school can be criminal behavior and, finally, imprisonment, which has been called "the final destination of exclusion." Longitudinal studies have showed, for example, that children whose parents have committed criminal acts are at risk of committing criminal acts, as well (Farrington, 2005; Gault-Sherman, 2011; Jaffee, Moffitt, Caspi, & Taylor, 2003; Jaggers et al., 2015; Lelekov & Kosheleva, 2008).From, this perspective, teachers' work is extremely challenging. They should be able to support students' strengths, trust in their abilities to learn, and notice the seeds of students' capabilities even when the students themselves do not seem to recognize their talents. Teachers should support every student individually (e.g., Milner, 2013). However, teachers with limited resources and with overflowing number of students in classrooms have to struggle to meet all expectations forced on them (see Chang, 2009). More often than not, teachers tend to focus on just some students or on just some learning areas. This means that, basically, teachers can provide students with remarkable good promises-or they can leave long-lasting, negative marks on them. If a student succeeds or does not succeed, it is not solely due to the teacher's actions, but the teacher's role is still important (Maatta & Uusiautti, 2012).That school is my weakest link, you know. I just fucked it up so badly when I think about it. It didn't have anything particularly bad or so. I guess I just didn't know how to be there, or something. It was just constant fighting and yelling. This is how I remember it.The role of teachers will be discussed in this article from the perspective of those students who have become excluded from school, tumbled into criminal life, and been imprisoned. The purpose is to provide new viewpoints for today's teaching and teacherhood and link them to the idea of caring teacherhood (see also Maatta & Uusiautti, 2012). This study pursues answers to the following research question: How do young prisoners describe good teachers in the light of their school experiences? It is not only interesting, but also relevant to know how these students talk about teachers and how they describe good teacherhood from their special perspectives. …

Image fusion can be viewed as a process that incorporates essential information from different modality sensors into a composite image. The use of bases trained using independent component analysis (ICA) for image fusion has been highlighted recently. Common fusion rules can be used in the ICA fusion framework with promising results. In this paper, the authors propose an adaptive fusion scheme, based on the ICA fusion framework, that maximises the sparsity of the fusion image in the transform domain

Abstract : Aircraft dead-reckoning navigation systems present particular problems in their assessment, and diagnosis in development where a continuous measurement of their error pattern is required. The inherent accuracy of modern inertial and Doppler equipment is such that there are few direct methods of measuring the system errors to the required precision. Need for long range, long duration flights over both land and sea with a continuous high accuracy reference led RAF to develop an integrated navigation system in which the outputs of a number of inertial navigation systems are recorded in parallel with those of Doppler radar, DME, Decca, Loran C and Omega. The recorded data is processed post-flight in a Kalman filter which is used to estimate the inertial system errors. The final reference is formed by compensating the inertial outputs for these errors and has the properties of high accuracy, low noise, and continuous availability. Although simple in concept, implementation of such a scheme is complex. The major problem lies in constructing suitable mathematical models of the various equipments. The second difficult area is that of obtaining the statistical information regarding the performance of the equipments in a form suitable for inclusion in the models. Although the reference is produced off-line the techniques can be implemented on-line.


Using a cross-sectional design, a self-rated questionnaire was used to accumulate data from RN students entering and exiting in three grades. The purposes of this study focused on: (1) understanding the motivations and the future plans to enroll in RN-to-BSN program; (2) describing and comparing the nursing competencies of RN students who studied in different grades; (3) identifying changes in nursing competencies before enrolling in the RN-to-BSN program and after one, two, and three years; and (4) determining the factors influencing the RN students' nursing competencies. Results in this study indicated that acquiring more professional knowledge and skill, earning the BSN degree, and facilitating promotion were the main reasons for studying in the RN-to-BSN program. Nearly half (45.5%) of the subjects would remain in clinical nursing work when they graduated from this program; 41.6% of the subjects wanted to change their jobs. Among six-dimensional nursing competencies for all RN students, the higher scores were in critical/dying care and professional development abilities; the lower scores were in teaching/collaborating, and planning/evaluating abilities. Comparing different grades, the third grade RN students had the highest scores in six-dimensional and total nursing competencies; the first grade RN students had the lowest scores. Next, changes in nursing competencies between before enrolling in the program and the time of conducting this study (after enrolling one, two, or three years) were identified. Those findings revealed that progress occurred in all students, especially in the second and the third grade RN students. Using a multiple regression analysis, five variables (i.e., grade, income, work specialty, motivation, and staff position) were deemed influential in leading to nursing competencies for RN students and accounted for total variances of 50.0%. Finally, recommendations were made regarding nursing education, nursing administration, and nursing research.


In this paper, literature survey of four wave mixing (FWM) effect in optical communication system for different number of inputs channels at various channel spacing. It reveals that FWM is minimum when minimum number of input channels with maximum channel spacing. It is also studied that on increasing the channel spacing, the interference between the propagating waves decreases and hence FWM effect also decreases. Also, on increasing the number of users or reducing the channel spacing, the interference between the input frequencies increases and thus the FWM effect also increases. Keywords— FWM, Number of users, channel spacing, BER, Q-factor, Eye Pattern.


Meticorterone (Prednisolone acetate) were injected into joints of 33 cases of rheumatoid arthritis, 172 times in total, with better results. Although intraarticular injection of prednisolone is, at present, to be one of the most effective treatment for rheumatoid arthritis, one must pay attention at the appearance of general effect in frequent and abundant injection. Comparative studies were performed on the effects of intraarticular injectons of prednisolone T. B. A, (on twelve cases), hydrocortisone acetate and meticorterone. Prednisolone T. B. A. was proved markedly longer effect in local with minimum general effect, It was, therefore, thought that prednisolone T. B. A. was safest and most effective in intraarticular therapy on the rheumatoid arthritis.


The method, which was developed by our group, enables us to perform quantitative analysis of living plants. It has been applied to investigate the transport of heavy elements such as germanium, gallium, bromine and arsenic in plants. These heavy elements are transported to the leaf through vascular vessel, and changes of their concentration with elapsed time after absorption could be clearly observed. It was confirmed that the movement depends on elements, on the manner of absorption and on the states of plant growth. In addition to the movement of supplied elements, some elements in the plant show interesting changes in response to proton irradiation. It was found that the method is quite effective for examining elemental movement in living plants.

In street lighting, there is a longstanding difference of opinion as regards what ought to be the scope and contents of a code of good practice. In Great Britain it is believed that an optimal situation will be arrived at by giving the lighting engineer a detailed prescription of how the lighting installation should be realized. A small number of standard solutions are indicated in the Standards, and the only thing the engineer has to do is to select the solution that is relevant to his particular purpose. In much of Europe, however, it is considered desirable to present functional requirements. The lighting engineer has to decide how he has to design the installation in his particular case in order to comply with those requirements; this viewpoint is also evident in the CIE Recommendations. Both


Neuroblastoma (NBL) exists in a complex tumor–immune microenvironment. Immune cell infiltration and tumor–immune molecules play a critical role in tumor development and significantly impact the prognosis of patients. However, the molecular characteristics describing the NBL–immune interaction and their prognostic potential have yet to be investigated systematically. We first employed multiple machine learning algorithms, such as Gene Sets Enrichment Analysis and cell type identification by estimating relative subsets of RNA transcripts, to identify immunophenotypes and immunological characteristics in NBL patient data from public databases and then investigated the prognostic potential and regulatory networks of identified immune‐related genes involved in the NBL–immune interaction. The immunity signature combining nine immunity genes was confirmed as more effective for individual risk stratification and survival outcome prediction in NBL patients than common clinical characteristics (area under the curve [AUC] = 0.819, C‐index = 0.718, p < .001). A mechanistic exploration revealed the regulatory network of molecules involved in the NBL–immune interaction. These immune molecules were also discovered to possess a significant correlation with plasma cell infiltration, MYCN status, and the level of chemokines and macrophage‐related molecules (p < .001). A nomogram was constructed based on the immune signature and clinical characteristics, which showed high potential for prognosis prediction (AUC = 0.856, C‐index = 0.755, p < .001). We systematically elucidated the complex regulatory mechanisms and characteristics of the molecules involved in the NBL–immune interaction and their prognostic potential, which may have important implications for further understanding the molecular mechanism of the NBL–immune interaction and identifying high‐risk NBL patients to guide clinical treatment.

The effects of various modifiers containing of lime, fly ash, dolomite, culture waste of edible fungi and chemical fertilizer on the quantities of soil microorganism, enzyme activities and tobacco yields were studied by field experiment. The results showed that the quantities of soil bacteria, actinomyces, phosphate - degrading bacteria, potassium silicate - degrading bacteria and cellulose - degrading bacteria, and the activities of soil peroxidase, urease, phosphatase and cellulosase in surface soil and tobacco yields in different modifier treatments were higher than those in the control. The quantities of the microorganism, enzyme activities and tobacco yields was increased by applying modifiers with culture waste of edible fungi Correlation analysis showed that the quantities of the five microorganisms and the activities of the four enzymes were closely related to the biomass and economical yields of tobacco. These results indicated that applying the modifiers could promote the reproduction of the soil bacteria, thus increased the activities of soil enzymes the economical yields of tobacco.


Intrinsically disordered proteins (IDPs) lack stable tertiary structure under physiological conditions. The unique composition and complex dynamical behaviour of IDPs make them a challenge for structural biology and molecular evolution studies. Using NMR ensembles, we found that IDPs evolve under a strong site-specific evolutionary rate heterogeneity, mainly originated by different constraints derived from their inter-residue contacts. Evolutionary rate profiles correlate with the experimentally observed conformational diversity of the protein, allowing the description of different conformational patterns possibly related to their structure-function relationships. The correlation between evolutionary rates and contact information improves when structural information is taken not from any individual conformer or the whole ensemble, but from combining a limited number of conformers. Our results suggest that residue contacts in disordered regions constrain evolutionary rates to conserve the dynamic behaviour of the ensemble and that evolutionary rates can be used as a proxy for the conformational diversity of IDPs. Significance Statement Intrinsically disordered proteins (IDPs) challenge the structure-function relationship paradigm. In this work we found that individual sites of IDPs evolve under a strong rate heterogeneity, mainly due to the structural constraints imposed by contacts between their residues. This can be better explained if the contacts are taken from selected subsets of their alternative native conformations, rather than from individual conformations or the whole native ensemble. From an evolutionary point of view, this result indicates that experimentally-based ensembles are redundant. We also observed that the evolutionary rates follow the structural variability between conformers, unveiling conformational preferences. Our results set the stage for establishing novel evolutionary-based methods to study IDP ensembles.


In the past 18 months, a number of significant operational events revealed unacceptable weaknesses in important barriers to sustained high levels of nuclear safety. Shortfalls in operations played a key role in many of these events. Of particular concern was an event at H. B. Robinson Steam Electric Plant involving inappropriate operator actions that challenged the integrity of the reactor coolant pump seals and made an electrical fire worse. Most of these events occurred at stations that are, by many measures, good performers. The underlying causes of these events involve all levels of the organizations and include inadequate recognition of risk, weaknesses in the application of significant operating experience, tolerance of equipment or personnel problems, and a significant drift in standards. Organizational and leadership shortfalls allowed these weaknesses to go unrecognized or uncorrected. This SOER provides recommendations to correct the situations that allowed these events to occur. In a May 2010 letter to U.S. nuclear utility chief executives, INPO chief executive officer James O. Ellis expressed concern about the dramatic increase in the significant operational events that occurred in the winter and spring of 2010. In his letter, Mr. Ellis asked the executives to share actions taken to increase the overall margin of nuclear safety. He also reported the formation of a working group of INPO and industry personnel to thoroughly analyze the events. The working group, consisting of site vice presidents and plant managers from 15 plants, met in June 2010 to discuss the common causes of nine domestic significant operational events. The group concluded that at the core of events were organizations that had not provided the prerequisite level of attention, thinking, and engagement to ensure plant activities were performed properly. In short, engagement in and consideration of activities and processes were insufficient. This group further concluded that ―process fixes‖ were not the solution to the underlying problems. The organizational weaknesses at the plants experiencing the events were believed to be widespread in the industry; indeed, participants in the industry group from plants


The invention provides a liquid phase dust collection method of solid dust collection slag of titanium tetrachloride. Titanium tetrachloride gas which contains ferric trichloride, ferrous chloride, aluminium trichloride and carbon particulates from furnace gas temperature control and dust collection processes enters a liquid phase dust collector from a lateral surface on the upper side of a dust collection tower, is mixed with liquid titanium tetrachloride sprayed down and then cooled and washed; ferric trichloride, ferrous chloride, aluminium trichloride and carbon particulates enter a titanium tetrachloride mud circulation tank together with liquid titanium tetrachloride, titanium tetrachloride gas without particulates after purification enters a leaching process from the upper side of another dust collection tower, and titanium tetrachloride containing particulates in the titanium tetrachloride mud circulation tank is transported to a heat interchanger through an submerged sludge pump and cooled, afterward, a part of the titanium tetrachloride enters a liquid phase dust collector for leaching and cooling, while the other part of the titanium tetrachloride returns to the temperature control and dust collection processes, where the temperature of furnace gas produced by chlorination is controlled, solid dust collector is controlled for collecting dust, and particulates back into the titanium tetrachloride is removed. The method has the advantages of saving energy and improving yield coefficient of titanium tetrachloride.
