The study of the high-pressure region of the ice phase diagram is very important for condensed matter and planetary physics [1‐ 3]. Furthermore, it sheds light onto one of the most important interactions in nature, namely, the hydrogen bond. However, the behavior of ice at high pressure is still largely unknown. The highest pressure investigated so far has been 1.28 Mbar [4]. Experimental and theoretical evidence seem to indicate that in this pressure range the crystal structure (ice X) is that of the cuprite, compatible with a symmetrized hydrogen bond [5‐8]. As to higher-pressure behavior there has been a number of intriguing proposals including metallization [5] and transition into antifluorite structure [5,9,10]. Here we study the high-pressure behavior of ice by using ab initio constant pressure molecular dynamics [11,12]. We demonstrate the dynamical stability of ice X, thus lending further theoretical support to the experimental conjectures, and we predict a phase transition from ice X to a new phase (ice XI) at ,3 Mbar and room temperature. Ice XI preserves the symmetric hydrogen bond and is a wide gap insulator up to and beyond 7 Mbar. In ice XI the oxygen atoms substructure becomes rather close packed in a distorted hcp structure. This new phase is stable up to 2000 K at 4 Mbar, where the system shows large protonic diffusion. Use of ab initio method is essential to describe the hydrogen bonding at these pressures, and constant pressure ab initio molecular dynamics method has proven to provide reliable prediction of new crystalline phases [11‐14] without any initial guess on the final structure. It is therefore ideally suited for the investigation of matter under these extreme conditions. In the dynamical simulation we adopted gradient corrections to local-density approximation for the exchange energy part following Becke [15]. This choice has been shown to describe well the hydrogen bonding in water [16]. Ultrasoft Vanderbilt pseudopotentials [17] were used for oxygen and hydrogen. The electronic wave functions were expanded in plane waves up to a kinetic energy cutoff of 40 Ry. This high cutoff turned out to be necessary to achieve convergence in the structural properties at 3 Mbar. An integration time step of 5 a.u. was used. For technical reasons we used the deuterium mass. This is uninfluential for the classical equation of state. Quantum corrections have been evaluated with the hydrogen mass. The sampling of the Brillouin zone was restricted to the G point of a1 6 H 2O molecule supercell. Starting from an ice VIII-like configuration [18], we equilibrated the sample at the pressure and temperature of 1.5 Mbar and 290 K. In this thermodynamic state the system assumed spontaneously an ice X structure. The oxygen atoms form a bcc structure and the hydrogen atoms sit midway between two neighboring oxygen atoms, leading to a symmetrized hydrogen bond. Further increase in the pressure at ,3 Mbar induced a change in the simulation box, reflecting a phase transition from ice X into a new structure. The new phase (ice XI) was identified to be orthorhombic with four H2O molecules per primitive cell. The space group is Pbcm with only one H2O molecule in the asymmetric unit. In terms of the two independent internal structural parameters u, y, the positions of the atoms are O at su, y, 1 d ,H 1 at s0, y2 1 , 1 d, and H2 at

In traditional malicious domain name detection algorithms, machine learning detection methods take a long time to extract features and the extraction methods are more complex; deep learning detection methods are easy to lose the semantic features of the entire domain name, and the detection results of a single neural network for different sample data sets are unstable . In response to the above problems, a malicious domain name detection method based on Doc2vec and hybrid network was proposed, and a new DLR (Doc2vec-LSTM-RNN) detection model was constructed. The word vector is constructed using the Doc2vec algorithm optimized on the basis of the Word2vec algorithm, which retains the semantic information of the domain name as a whole; and mixes the bidirectional LSTM network and the bidirectional RNN network in series to carry out deep-level feature extraction and enhance the robustness of the detection model; finally the Softmax function is used to output the classification result. Experimental data shows that this method has excellent performance in malicious domain name detection. Compared with traditional machine learning and deep learning detection methods, it has higher detection accuracy.


In this contribution, we describe the seabed cabled observatory networks managed by Ocean Networks Canada (ONC). The focus is on the hydrophone hosting capabilities of ONC's advanced science infrastructure and on the assets already in place, together with their scientific objectives. We describe the data acquisition and archival principles and methods, as well as the derived products available to users. We also elaborate on the concerns of the United States and Canadian Navies with quasi real-time, public data and on the mitigation measures in place to balance security needs with the scientific and public safety goals of the instrumentation. Finally, we describe the potential for instrument development and testing that ONC offers on its networks.


As robotic systems become more interactive and complex, there is a need to standardise interfaces and simplify development processes. This is particularly pertinent in the field of manufacturing, where human-robot collaboration is on the increase, but where standards and proprietary software are key barriers to deployment and adoption.In this article we present the ROSIE Adapter, a general-purpose, modular adapter developed in ROS designed to support the creation and connection of industry-ready digital twins. Together with our previous work on the modular CSI digital-twin framework, we demonstrate how the ROSIE Adapter creates a versatile "plug-and-play" interface that simplifies the development of new robotic processes, and improves accessibility to novice users. Furthermore, the adaptor supports integration of intuitive interface devices, such as speech and augmented reality interfaces, which enable more natural collaboration. We describe the adaptor and its use in two real-world applications, demonstrate the ease of use via a three-day hackathon event, and provide results showing the faithfulness of the arising digital twins to their connected physical systems.

In this article, a defected ground structure (DGS) is proposed to replace the inductor placed between common source and common gate stage in cascode low‐noise amplifier (LNA), leading to silicon area reducing as well as good internal matching condition. For verification, a 28 GHz three‐stage cascode LNA with DGS is designed and implemented in a 130‐nm CMOS technology. The fabricated prototype achieves a peak gain of 20 dB and minimum noise figure of 5.2 dB. The LNA occupies small silicon area of only 0.12 mm2 excluding testing pads, and it draws a current of 16 mA from a 1.5 V supply voltage.


In this paper we review recent work on the stochastic approach of Walsh spectral analysis. We are mainly interested in the properties of the finite Walsh transform, which in turn allow us to derive properties of the estimators of the Walsh spectrum. We further discuss linear dyadic filters and Walsh characteristic functions. A rather complete list of references is given.


The objective of the present study was to investigate the impact of increasing doses of cold-pressed Camelina sativa oil (CO) with high level of αlinolenic acid (56.1%) on plasma and liver lipids as well as on oxidative level of Sprague-Dawley rats fed with high fat diets (HFD) containing 20% fat and 1% cholesterol. The effect of 1.1, 2.2 and 4.4 g/kg b.w. CO were studied with 2.2 g/kg b.w. fish oil as positive control. After six weeks, 4.4 g/ kg b.w. CO and 1.1 g/kg b.w. fish oil significantly lowered the increase of body weight gain, liver weight gain, total cholesterol (TC) and total triglyceride (TG) in liver and plasma, (low degree lipoprotein + very low degree lipoprotein)-cholesterol [(VLDL+LDL)-C] and aspartate amino transferase (AST) in plasma resulted from high-fat diets (P < 0.05), in which CO acted in a dose-dependent manner. The increase of plasma high degree lipoprotein 3 (HDL 3 ) and plasma lipoprotein displacement in agarose gel electrophoresis of high-fat diet fed rats ingested CO also showed that CO could promote the metabolism of HDL subset to miniaturize the HDL particles. Liver protection by CO was further substantiated by the improved liver histological findings in HFD fed rats. However, fish oil and CO did not have effect on decreased antioxidation level resulted from high-fat diets. These data suggest that CO participates in the normal regulation of plasma lipid concentration and cholesterol metabolism in the liver. Thus, Camelina sativa oil containing a high level of α-linolenic acid possesses lipid-lowering activity by regulating the blood lipid metabolism and protecting liver function.

In turbomachinery, blade crack detection methods are beneficial for condition-based maintenance and for reducing the risk of catastrophic failures due to high cycle fatigue of bladed disks. A crack can be more easily detected in a perfectly tuned bladed disk (i.e., with identical blades and sectors). That is because the crack causes mode distortion and possibly response localization. Unfortunately, perfectly tuned bladed disks are an idealization since small blade mistuning is unavoidable and it can also cause mode distortion and response localization in bladed disks. A detection method has been recently developed to detect the presence of a crack in a mistuned bladed disk and to identify which blade is cracked. The method requires multi-point measurements of all blades (e.g., obtained by using tip-timing techniques) and is based on the observation/assumption that the dynamic response of a cracked bladed disk cannot be represented as a linear combination of modes of the tuned system. This paper introduces a method which uses a similar physical basis for detection, but requires fewer measurements, namely one measurement location per blade (e.g., obtained using tip-timing methods). The key idea is to focus on isolated modes (or isolated mode pairs) which are sensitive to the presence of a crack rather than on an entire mode family (with high modal density). The novel method also extracts spatially correlated vectors from the nonlinear (forced response) measurement data of the cracked bladed disk to be used for crack identification.


Superconducting Radio Frequency (SRF) cavities are the primary choice for accelerating charged particles in high-energy research accelerators. Institutions like Fermilab use SRF cavities because they enable significantly higher gradients and quality factors than normal-conducting RF cavities and DC voltage cavities. To cool the SRF cavities to low temperatures (typically around 2 K), liquid helium refrigerators are used. Producing and maintaining the necessary liquid helium requires large, elaborate cryogenic plants involving dewars, compressors, expansion engines, and recyclers. The cost, complexity, and space required for such plants is part of the reason that industry has not yet adopted SRF-based accelerators. At the Illinois Accelerator Research Center (IARC) at Fermilab, our team seeks to make SRF technology accessible not only to large research accelerators, but to industry as well. If we eliminate the complexity associated with liquid helium plants, SRF-based industrial accelerators may finally become a reality. One way to do this is to eliminate the use of liquid helium baths altogether and develop a brand-new cooling technique for SRF cavities: conduction cooling using a cryocooler. Recent advances in SRF technology have made it possible to operate SRF cavities at 4 K, a temperature easily achievable using commercial cryocoolers. Our IARC team is taking advantage of this technology to cool SRF cavities.


Bacterial lipopolysaccharide (LPS) activates the immune system and induces increases in peripheral cytokines, which, in turn, affect the endocrine system. In particular, LPS-induced cytokines stimulate the hypothalamic-pituitary-adrenal axis to increase levels of antiinflammatory-acting glucocorticoids. In the present work, we show that LPS directly stimulates interleukin (IL)-6 release by mouse pituitary folliculostellate (FS) TtT/GF tumor cells and FS cells of mouse pituitary cell cultures. The stimulatory effect of LPS was strongly enhanced in the presence of serum, suggesting that LPS is only fully active as a complex with LPS-binding protein (LBP). Both TtT/GF cells and mouse pituitaries expressed CD14, which binds the LPS/LBP complex, and Toll-like receptor type 4, which induces LPS signals. LPS increased phospoinositol turnover in TtT/GF cells and induced phosphorylation of p38α mitogen-activated protein kinase and the inhibitor (IκB) of nuclear factor-κ B. Nuclear factor-κ B was activated by LPS i...


Juvenile Delinquency refers to criminal acts committed by children or teenagers, particularly less than eighteen years of age. Juvenile delinquency known as juvenile offending or youth crime is participation in illegal behavior by minors (juveniles) individuals younger than the statutory age of majority. Most legal systems prescribe specific procedures for dealing with juveniles like juvenile detention centres and courts. Common sentiment on this issue is that the crimes they commit affect society and offend the children. Present study explored the juvenile delinquents and their main socio-economic factors leading them to commit a crime. Study was conducted in Faisalabad and Bahawalpur districts of Punjab province. Two borstal institutions and juvenile jails are located for juvenile's rehabilitation in study districts. The respondents were male delinquents of 13-18 years age living in the selected districts. Total 140 respondents (70 from each jail) were selected through simple random sampling technique. Data were collected with the help of a well-designed interview schedule. Data were analyzed using Statistical Package for Social Sciences. Findings revealed that about 72% respondents were literate with maximum age of 17-18 years (47.1%). Majority of respondents' parents were educated. However, 40% fathers and 46.4% mothers were found illiterate. About 65% respondents' annual income was falling in between 5000-15000 clarifying their state of poverty. Therefore, children were compelled to join bad acts like Dacoity, theft etc. about 34.3% respondents committed a murder followed by 16.4% performed Dacoity and 12.9 indulged in theft. Chi Square analysis accepted both of the hypotheses that Family structure influence the juvenile delinquency and Peer group influence the juvenile delinquency. Study recommended that to keep children safe from social evil its mandatory to monitor their activities and treat them with affection and equality. Electronic media should disseminate positive messages for the youth encouragement and capacity building.


The acid-base behaviour of the N-2-(4-amino-1-methyl-5-nitroso-6-oxo-1,6-dihydropyrimidinyl) potassium L-alaninate (KL) and its reactivity with Ag(I), Cd(II) and Pd(II) metal ions have been studied. Three solid species with formulae AgL?3H O, CdL ?6H O and 2 2 2 1 13 PdClL?H O have been obtained and characterized by IR, H and C NMR spectroscopic methods and thermal, conductivity and magnetic 2 4 measurements. The structure of hAg((h -m -L)]?3H Oj has been established by single-crystal X-ray diffraction and consists in a 3 2 n 3D-polymer. Within the polymer each Ag(I) ion is tetrahedrally coordinated to three differents L anions, while each ligand is coordinated 4 in a rather unusual h -m coordination mode. Spectroscopic data show a similar coordination mode for the Cd(II) complex, while for the 3 Pd(II) one a different coordination mode is proposed.  1999 Elsevier Science Ltd. All rights reserved.


Hospitalization may contribute for subnutrion/dehydration of inpatients, particularly of older people. Insufficient evaluation of alimentary and hydric standard, lack of supervision and delegation are some of the causes for this multifactor problem. For the solution of this problem the changes in the dynamic of organization, change in nurse's priorities and modification of the involving environment can contribute.


Serological techniques are recommended procedures for the identification of Mycoplasma species. They enable separation of mycoplasmas at the species level and are widely used for practical laboratory identification of the isolated microorganisms. However, complex growth media are required for the isolation of Mycoplasma species and some strains of pathogenic Mycoplasma species grow very fastidious and can not be cultured. Introduction of DNA based diagnostic methods in mycoplasma research enabled survey of the whole genome in a single assay and reveal also information about noncoding regions of the genome. Restriction enzyme analysis is a powerful method for differentiation of close related strains but requires high quality of DNA which can only be obtained from cultured mycoplasmas. The increasing number of cloned mycoplasma genomic fragments are successfully used for identification and differentiation of mycoplasma strains and species in hybridization studies. The polymerase chain reaction enables identification and characterization of mycoplasmas without culture directly from clinical material. Large genomic sequencing projects produced complete nucleotide sequence from two Mycoplasma species and several more are in progress. This data will open the possibility to understand better the biology of mycoplasmas.


In network management, the Request-Reply(RR) model in Simple Network Management Protocol(SNMP) leads to the general disadvantages of overfull traffic, and sometimes-intolerable time lag. To overcome them, this paper proposes a Register-Distribute(RD) model, in which a concept of the object attributed table and its organizing style are given. To achieve it, the Management Information Base(MIB) is extended to constrain the behavior of every agent, and one distribution protocol is designed to support the novel RD model and resolve the compatibility between RR model and RD model. Experimental results show that the RD model decreases the traffic, and avoids the time lag effectively. Therefore, the proposed RD model can make the SNMP more efficient than the traditional RR model.

n-iated and further collections made. Hatchability percentages after mating are those expected from outcrosses, which these matings were. Each of the 1,226 eggs collected from the 33/11-o females was examined especially for evidence of having been stung. Twelve (0.97 per cent.) were recorded as "possibly injured." They were somewhat wrinkled but contained what appeared to be normal yolk in contrast to the dry "shells" described above. They did not hatch. The mothers in this experiment were young, and only seven "shells" were laid. If it is believed that these two groups represent stung eggs, then 1.54 per cent. (19 among 1,226) were stung. A final observation of considerable importance in this discussion is that almost every egg which fails to hatch continues development after it has been removed from the container with females and dies at a later embryonic stage. This agrees with Spotkov's observation that almost every egg undergoes cleavage. From these studies the author concludes either (1) that females sting eggs very rarely or (2) that stung eggs can continue development after such injury and (3) that normal cleavage and even blastoderm formation are no indication of ultimate hatching.

A vital staining technique with fluorescein diacetate (FDA) and propidium iodide (PI) was used for determination of viability of myxosporean stage spores of Myxobolus artus and actinosporean stage spores of M. cultus. Viable spores stained green with FDA and non-viable spores stained red with PI were clearly distinguishable in M. artus myxosporean spores released from live infected fish, while the spores collected from pseudocysts were not well stained with FDA. Immediately after release from the oligochaete, Branchiura sowerbyi, actinosporean spores of M. cultus, stained bright green in the sporoplasms and red in the spore processes. In vitro survivability tests revealed that the longevity of M. artus spores was 5 months at 25°C and 15 months at 18°C. Drying and ultraviolet irradiation (36 000 mW s cm–2 for M. artus myxosporean spores, 600 mW s cm–2 for M. cultus actinosporean spores) were most effective as sporicidal treatments.

The invention provides a turbocharging system with a self-regulated-volume exhaust pipe and belongs to the technical field of internal combustion engines. The turbocharging system comprises a cylinder, an exhaust pipe, a turbine, a connecting pipe, a casing pipe, a baffle ring and an elastic component, wherein one opening end of the connecting pipe is connected with the tail of the exhaust pipe, the other opening end of the connecting pipe stretches into the opening end of the casing pipe, the baffle ring is arranged in the connecting pipe, and the elastic component is arranged between the baffle ring and the back wall of the casing pipe. When the engine is in a low-speed working condition, the back wall of the casing pipe can move toward the direction close to the baffle ring, thus the exhaust pipe volume can be relatively smaller, the pulse energy can be fully utilized, the inlet pressure of the engine can be higher and the overall performance of the engine can be better; when the engine is in a high-speed working condition, the back wall of the casing pipe can move toward the direction far from the baffle ring, thus the exhaust pipe volume can be relatively larger, the pumping loss can be less and the overall performance of the engine can be better. The turbocharging system with the self-regulated-volume exhaust pipe provided by the invention is reasonable in design and simple in structure and can be applied to the turbocharging system which has only one turbine inlet and is laterally provided with the turbine.

Background: Depression in adolescents is one of the major public health concerns that can affect educational attainment and social relationships and impose a high economic burden on society. Previous studies have provided limited information on the relationship between a healthy diet and depression in adolescents. The present study aimed to investigate the association of Healthy Eating Index-2015 (HEI-2015) with depression scores among adolescent girls.
Methods: This cross-sectional study was conducted on 734 adolescent girls aged 12-18 years. Data on dietary intakes were collected using a valid and reliable food frequency questionnaire (FFQ), and diet quality was assessed based on HEI-2015. The Iranian validated version of Beck Depression Inventory (BDI) was used to evaluate depression. To explore the association between HEI-2015 and depression, logistic regression was used in crude and adjusted models.
Results: The prevalence of a high depression score in the study population was 33.8%.  After controlling for potential confounders, girls with the highest adherence to HEI-2015 compared to those with the lowest adherence had a 37% lower prevalence of depression (OR: 0.63; 95% CI 0.40 to 1.00, Ptrend=0.03). This finding remained significant after adjustment for confounding variables (age, energy intakes, physical activity, and BMI percentile).
Conclusions: Greater adherence to HEI-2015 was associated with lower odds of depression in female adolescents. Prospective studies are necessary to confirm these results and clarify whether a causal relationship exists.


While previous studies have tested the mediating or moderating effects of select factors on disordered eating pathologies, no empirical studies have examined a moderated mediation model. Thus, fill...

In this research work, a new and simple design method of a compact slot antenna with dual notched bands is demonstrated for ultra-wideband (UWB) wireless networks. The presented antenna design is printed on a low-cost FR-4 substrate. Initially, an antenna with improved impedance bandwidth is designed. This is archived by employing an extra slot with two T-shaped strips which increases the upperfrequency band of the design from 9 to 15 GHz. Later, undesirable bands including 4GHz C-band, worldwide interoperability for microwave access (WiMAX) at 3.5/5.5 GHz (3.3 to 3.7 GHz and 5.15–5.85 GHz), wireless area network (WLAN) systems at 5–6 GHz (5.15–5.35 and 5.725– 5.825 GHz) are eliminated by modifying the upper layer of the antenna using the protruded L-shaped strips inside the square radiation stub and the protruded E-shaped strip inside the feed-line. The proposed antenna offers quite good fundamental properties in terms of impedance bandwidth, gain, fidelity, radiation pattern, etc. A good agreement is observed between the measured and simulated results. Due to the simple structure and excellent performance of the design with controllable bandnotch function, the presented microstrip antenna is useful for modern UWB wireless networks and can be an attractive candidate for portable internet of things (IoT) sensors.


Though many biological studies have been made on the commercial-sized herring, Clupea harengus pallasi, in the northern part of the Okhotsk Sea in summer, knowledge on the dis-tribution and biological characteristics of the juvenile in the same period is inadequate even today. The authors studied informations obtained from the measurements of about 2400 samples. The samples were obtained by surface gill nets, varying in mesh size from 30mm to 82mm, used for capturing juvenile salmon, and the samplings were conducted on the research vessel "Oyashio Maru" in the northern part of the Okhotsk Sea from August 17 to September 3, 1971. The results obtained are summarized as follows: 1) The shoals, composed of middle and large-sized fish (20-33cm) were found in the area off the Koni Peninsula, the small-sized fish (12-15cm) in the area off the Okhotsk, and the medium-sized fish (18-26cm) in the area off the Ayan. The area, where each shoal appears, seems to vary yearly. 2) The fish of 2-3 age were observed in comparative warm waters (13-14°C) in 1971, 12-13°C in 1970 (Unpublished data). 3) Samples of the 4 age, caught in the area off the Ayan, were smaller in their average fork length, and heavier in the ratio of body weight to fork length, and higher in the mean maturity index {gonad weight×102/(body weight-gonad weight)} than those from the area off the Koni Peninsula. There is a possibility that the fish in the area off the Ayan may not belong to the Okhotsk population.

Aerogel blankets are composites of silica aerogel particles dispersed in a reinforcing fiber matrix that turns the brittle aerogel into durable and flexible insulating materials. In this study, silica aerogel was loaded on glass wool with different concentrations (0–18.6%) and morphological and thermal characteristics of the aerogel blankets were studied. Rate of modified blanket decomposition was slower at temperatures between 250°C and 650°C due to the retardant effect of the silica aerogel. The average diameter of the fiber for either original glass wool or modified glass wool materials was approximately 20 μm and samples had porous, interconnected particles with dendritic-like structure.


"The Red Chamber's Dream" from the middle of 18th century is the youngest of Chinas "Four Great Classical Novels". In the cloak of traditional story-telling it deploys a plenitude of narrative modes – realistic, psychological, symbolist fabulating. Written in colloquial Chinese (Beijing dialect) it has become an important source for establishing modern Standard Chinese (putong hua) in the sway of the 'New Cultural Movement' since the 1920ies. Highly appreciated by Mao Zedong, the communists tried to enforce a "progressive" appreciation of the novel.

In this letter we propose a very simple strategy for combining space-time block coding (STBC) with code division multiple access (CDMA) to be used in single-user links or in broadcasting over time-dispersive channels. The proposed system provides the desired space diversity gain and is capable of perfect cancellation of multiuser interference (MUI) and intersymbol interference (ISI), using a very simple receiver structure. The advantage is obtained by simply incorporating cyclic prefixes in the user codes. We provide a theoretical analysis, verified via simulation results, and a comparison between CDMA and OFDMA systems incorporating STBC.


For the last several years, we have ended the year with a questionnaire looking into the future. Our panel was asked what was the greatest threat to our industry. Consistently, they have answered {open_quotes}the lack of real growth.{close_quotes} This year was no exception, but this time there was a feeling that something could and would be done. Almost every marketer (98%) said he or she supported the check-off program that would raise considerable funds for public relations and research. This idea isn`t new; it has been discussed year after year. Always the stumbling block was how to raise funds so that each company contributed and no one had a free ride. Last year, it was proposed that a commission created by federal law, be established to oversee funds for the education of consumers and government and provide technology research. If Congress authorizes this plan and members of the industry endorse it, we would have a strong program in place by 1997.

Source of material The title compound was synthesized by stirring CuC4O4 [1] in ethylendiamine for 20 min at room temperature. After filtering the blue solid was dissolved in water. Slow evaporation of the solvent yielded violet block-shaped crystals. Experimental details All hydrogen positions were determined from difference Fourier maps. Hydrogen positions, as well as their isotropic displacement parameters were refined freely. Discussion Diamine complexes of copper(II) in general [2,3] and diaminocopper(II) squarates in particular [4] have been studied intensely, concerning, amongst others, their thermochromic behaviour. The title compound, [Cu(C2H8N2)2(H2O)2] (C4O4) · 2 H2O, was obtained within our investigations on the reactivity of anhydrous copper squarate [1]. The monoclinic structure comprises two formula units per unit cell. The Cu atoms of the [Cu(C2H8N2)2(H2O)2] cations, as well as the barycenters of the C4O4 anions are located on centers of inversion (figure, top). The copper atoms exhibit a [4+2] coordination with four equatorial Cu—N bonds being 2.008(1) Å and 2.025(1) Å, respectively (figure, bottom), and the axial Cu—O bonds being 2.54(1) Å, similar to the coordination of copper in the related (N,N-dimethyl-ethylenediamine)copper squarate reported by Ucar et al. [5]. The two remaining water molecules are not coordinating to the metal. Z. Kristallogr.

We have developed a model for friction in a dry granular material,that allows multiple reversible transitions between stick and slipcontacts. The ultimate purpose of the model is to simulatedeposition processes. During these processes a pile structure isformed that is repeatedly destabilised by addition of new material.The present model does not yet include rotation. The model is testedfor a few simple systems. Finally we perform more extensive granulardynamics simulations using the model for 2D and 3D systems. In eachsystem, a steady flow of material is dropped onto a rough surface. DOI :  http://dx.doi.org/10.22342/jims.18.104.22.168-189


The aim of this study is to examine the perception of cohesion in highly interdependent sports teams, compare cohesion in different sports, and then compare social and task cohesion. The participants were 205 professional sports players in the city of Belgrade, Serbia. They are engaged in five different sports: Football/soccer, basketball, volleyball, handball, and water polo. The Group Environment Questionnaire (GEQ) was used to collect the data. All the analyses were carried out with the SPSS 22 statistical software. The results have shown moderately-high levels of all four aspects of cohesion (Group Integration-Task, Group Integration-Social, Individual Attractions to the Group-Task, and Individual Attractions to the Group-Social) in all sports. Overall, perception of task cohesion is higher than perception of social cohesion. The study also reveals that the type of sport played impacts the level of cohesion, with basketball players having the highest scores of all.


The paper complements earlier reviews by further examining thirteen years of academic IT sourcing studies. It finds them rich with much empirical survey and case research findings, but still marked by inconsistencies, a plethora of concepts, research approaches, ambivalent terminology, and a lack of consistency and common focus across different research groupings. It then looks at a limited set of internally consistent research studies carried out by the authors to come to more positive conclusions about how in detail, organizations have moved up the IT sourcing learning curve. This learning is classified under four headings: assessment of the back-office portfolio; evaluation of market options; the crafting of outsourcing arrangements and the management of external relationships. The paper concludes by offering five areas for future research in IT sourcing.


Missed guidewire is a rare and potentially avoidable complication of central venous cannulation. Unsupervised insertion by trainees, distraction during insertion, and high workload may increase the risk. Simple measures such as holding onto the wire at all times until removal from the vessel, routine use of central venous catheter insertion checklist, and vigilant supervision of the trainees may help prevent missing of the guidewire.


The binaural trading ratio (Δt/ΔI) is traditionally measured by opposing an interaural time difference (Δt) with an interaural intensity difference (ΔI) in proportions sufficient for apparent cancellation of the perceptual effects of the two cues. In a previous paper [E. R. Hafter and S. C. Carrier, J. Acoust. Sac. Amer. 46, 125 (A) (1969)], we showed that no combination of Δt and ΔI produces a dichotic tone which cannot be detected as different from an otherwise comparable diotic. In that paper we proposed a "dual‐threshold" model in which intensive and temporal information are encoded by peripheral dual‐threshold devices. The two sets of information are then weighted and recombined by a central processor. An important test of the model is the response to signals of levels sufficiently low as to render the high threshold device functionless. In this study, we measured the tradability of Δt and ΔI at overall levels of 20 and 40 dB SPL. At these levels, Δt and ΔI apparently do cancel, but the signal remain...

During past few years there were several types of Landslides Early Warning Systems developed in the world wide. Mainly Asian countries which effect by south-west and north-east monsoon rainfall are mindfulness for this objective. Due to weather changes landslides become more frequent and cause damage to people. In this situation people need complete landslide early warning system to protect their resources. The implementedsystem is capable of predicting a possible landslide in a given area and issuing warnings that would assist in risk management. This research project has a low-cost, sustainable early warning system to send warning alerts via Short Message Service (SMS) to monitor the landslides. The system uses data mining to identify what are the most dangerous areas for landslide. After that,the sensors are placed in the areas to detect landslides. System calculate values what are the probability for a landslide to happen be high. Then the system will generate a warning Alarm and warning message and it will send to people with using Siren and SMS or Android application. System administrator can handle this system using his Desktop application.

Abstract Objectives To identify titanium particles (TPs) in biopsy specimens harvested from peri‐implantitis lesions and secondarily to study the histopathological characteristics in peri‐implantitis compared to periodontitis, in order to evaluate whether the presence of TPs could alter respective inflammatory patterns. Material and methods Biopsies containing granulation tissue were harvested during routine surgical treatment in 39 peri‐implantitis cases and 35 periodontitis controls. Serial sections were obtained using titanium‐free microtome blades. The first and last sections of the peri‐implantitis specimens were used for identification of TPs by scanning electron microscopy coupled with dispersive X‐ray spectrometry. Intermediate sections and periodontitis specimens were processed for descriptive histological study using haematoxylin–eosin staining and for immunohistochemical analysis using CD68, IL‐6, Nf‐kB and VEGF markers. Results TPs were identified in all peri‐implantitis specimens as free metal bodies interspersed within granulation tissue. However, presence of macrophages or multinucleated giant cells engulfing the TPs were not identified in any specimen. Peri‐implantitis granulations were characterized by a chronic inflammatory infiltrate rich in neutrophils. About half of peri‐implantitis patients exhibited a subacute infiltrate characterized with lymphocytes interweaved with neutrophils and eosinophils. When compared to periodontitis, peri‐implantitis tissues showed higher proportions of macrophages and a more intense neovascularization, based on significantly higher expression of CD68 and VEGF respectively. Conclusion TPs were identified in all peri‐implantitis specimens, but without evidencing any foreign body reaction suggestive for direct pathological effects of TPs. The peri‐implantitis granulation tissue was characterized by intense neovascularization and presence of a chronic inflammatory infiltrate dominated by plasma cells, neutrophils and macrophages.


SUMMARY

Of 444 compounds tested for their ability to stimulate eggs of Heterodera rostochiensis to hatch, forty-five did so to varying extents. Many compounds that hatched H. schachtii Schm. eggs did not hatch H. rostochiensis eggs. The most effective compounds with H. rostochiensis were picrolonic acid, anhydro-tetronic acid and vanadates. Tests with analogues of picrolonic and anhydro-tetronic acids suggested some structures that may be concerned in hatching H. rostochiensis and H. schachtii. The simple analogues hatched the eggs of H. schachtii but not those of H. rostochiensis. Suitably placed polarisable atoms seemed to be an essential feature. Picrolonic acid contains pairs of polarizable atoms, about 4 and 6·7 A apart, that may respectively be associated with the hatching of H. schachtii and H. rostochiensis. Other features of the more active hatching agents were a cis and co-planar arrangement of the two polarizable atoms with respect to the rest of the molecule. The function of hatching agents is discussed.

ABSTRACT:
In this paper, we present first experiences withthe use of a lightweight, media-supporting quiz application for mobile devices. The idea is to use the students' own smartphones as devices and provide a quiz administration module which is integrated into the existing collage e-learning platform. For establishing the link between the devices and the platform we use dynamically generated Quick Response (QR) codes. The quiz is implemented as a mobile application. We evaluate our approach with respect to usability, limitations of the computers, the QR code, and the impact on the collage network infrastructure. Furthermore, we discuss the usefulness and usability of the quiz tool on the base of students' evaluations and our experienceswhile giving online tests.

The work of the use of QR code recommends a setup of an automated examination system to process, exams, marks, score, grade and report on these assessments. Although the system has the potential to make the questions paper easily available to students using the QR code also it is handy for the students to give the answers to the questions which is time saving for teacher as well as students and also checking is error free. Automated exam process using QR code technology simplifies the conduction of examination by direct access of questions to the Exam-Taker directly on his handset and automating the write process ranging from validating the answer to providing the result of the exam.

Several members of a novel class of w-substituted asymmetric bolaform surfactants have been synthesized in order to investigate their surfactant and biological properties. The ω-hydroxy trialkylammonium and pyridinium surfactants have significant antimicrobial and antifungal activity relative to their conventional analogues. For conventional quaternary ammonium alkyl surfactants, increasing the hydrocarbon chain length causes a decrease in the surfactant monomer solubility and a corresponding decrease in the biological activity. No such trend is observed for the ω-hydroxy quaternary ammonium bromide series.

The challenge of generating high-quality clinical evidence on the efficacy of a treatment is humbling enough. But translating this clinical evidence into clinical practice takes a similarly dedicated effort and a rigorously derived evidence base of its own. Nowhere is this challenge more apparent than with the example of thrombolysis for acute ischemic stroke. Despite concerted and sustained efforts to increase access to this therapy in the 17 years since clinical efficacy was first demonstrated,1 thrombolysis for acute ischemic stroke has remained stubbornly underutilized.2

Although delays in initial presentation are perhaps the most important contributor to the unrealized potential of thrombolysis,3 the barriers to the effective and efficient delivery of this therapy at the hospital level have prompted efforts to develop and refine organized systems of care for acute stroke.4 Although …


In this research, thermal effect on the natural fre quency of axisymmetric free vibration of a thin nan o circular plate made of functionally graded material will be studied. Therm al distribution has been assumed uniform and proper ties of the materials are changing through the thickness of the plate. The mo dified couple stress theory has been used for consi dering the length scale parameter and the governing equation of motion and boundary conditions are obtained using the Hamilton 's principle and based on the classical plate theory. The analytical solution for the clamped and simply supported boundary cond iti s are established utilizing the Bessel functions. The results show that by incr easing the temperature changes, ratio of the thickn ess to length scale parameter, ratio of radius to thickness and power-law index, t he natural frequency decreases at both boundary con ditions. The effect of increasing ratio of the thickness to length scale p rameter in clamped boundary condition is more than simply supported boundary condition but for higher ratios, this effect decrea s s at both boundary conditions. The effect of incr easing temperature changes in simply supported boundary condition is more than cl amped boundary condition such a way that the lower temperature changes lead to the nonlinear behavior of the plate.

In recent years, global warming and the energy crisis have accelerated the development of electric vehicles and hybrid electric vehicles, which has put forward an ever-growing demand for lithium-ion batteries (LIBs) with even higher power density and longer cycle life. [ 1 ] The electrochemical performances of the electrode materials are strongly dependent on their sizes, morphologies, and structures; therefore, to meet the requirements, many efforts have been devoted to designing novel nanostructured electrode materials. Extensive research has proved that nanomaterials can achieve higher specifi c capacity and better cyclability compared with their bulky counterparts, due to the decreased diffusion lengths, enhanced kinetics and large ionic contact area. [ 1a , 2 ] Owing to their high surface energy, nanoparticles however tend to self-aggregate, which reduces the effective contact areas among the active materials, conductive reagent, and electrolyte. [ 3 ] So it is crucial to retain the large contact to fully fulfi ll the advantage of active nanomaterials. Recently, hierarchical structures composed of various building blocks on the nanoscale have attracted great attention as a new class of electrode materials, which synergistically enhance the features of both micromaterials and nanomaterials. In such structures, the nanoscale dimension of building blocks promotes the kinetics of Li + -ion storage due to the shortened diffusion paths, while


The use of multilevel inverters has become popular in recent years for high power applications. Various topologies and modulation strategies have been reported for utility and drive applications in the recent literature. This paper is devoted to the investigation of a 500 hp induction motor drive based on a seven-level 4.5 kV hybrid inverter. The topological structure and operating principles of the proposed approach are presented. Various design criteria, spectral structures and other practical issues such as capacitor voltage balancing are discussed. The feasibility of the proposed approach is verified by computer simulations.


ATP content obtained by luciferin-luciferase luminometry with commercially available reagents provided rapid estimates of Ureaplasma urealyticum populations. Each cell contained about 4.7 X 10(-18) mol of ATP. We could detect 10(4) CCU50 (color change unit50) per 100 microliters. We correlated urease activity with growth and confirmed the differential response of ureaplasma strains to Mn2+.


We read Massicotte et al's recent report of dramatic reduction in bleeding and transfusion in patients undergoing phlebotomy with low central venous pressure (CVP) during liver transplantation (LT) with great interest, and offer several comments and questions. Of the 98 patients enrolled, it appears that only 58% were able to undergo phlebotomy presumably due to a combination of baseline anemia and hypotension after anesthetic induction. Of those, a relatively small volume of blood ( 10ml/kg) was removed, with modest reductions in CVP. This patient cohort was relatively healthy (in terms of the average liver transplant candidate), somewhat preserved baseline coagulation parameters and without renal impairment. In addition, all patients received aprotinin (% of control group receiving aprotinin not stated) and a quarter received cell save blood compared to none in the control group. Given the potential impact of these two therapies, as well as changes in anesthetic or surgical techniques over 5 years, can the authors ascribe the dramatic reductions in blood loss and blood product transfusion solely to phlebotomy and lower CVPs, considering that 40% of the group did not undergo phlebotomy? Any efforts to decrease blood loss and transfusion during LT is welcomed and the authors' data in this study are startling. However, given the inherent problems with historical controls (as acknowledged by the authors), caution must be exhibited in concluding causality and association. What the authors' data does suggest is that in a relatively healthy cohort (MELD 20), without anemia, severely abnormal baseline coagulation parameters, or renal abnormality (and wouldn't we all love to have those patients), those patients that tolerate minimal hemodilution may benefit from the subsequently lowered CVP. As the authors conclude, despite the difficulties of a prospective randomized investigation of this question, data of this potential implication deserves such investigation.

Genentech and the Cambridge, Mass.-based start-up Constellation Pharmaceuticals have inked a broad pact to develop cancer drugs based on epigenetic targets. Genentech will shell out $95 million to cover an upfront fee and three years of research funding. The biotech giant also has an option to acquire Constellation down the road. Epigenetic processes dictate how genes are expressed by adding, removing, or interpreting chemical modifications to chromatin, the compact structure within a cell's nucleus that includes DNA and proteins called histones. The alterations to chromatin are made without compromising the underlying DNA. Under the agreement, Genentech and Constellation have committed to exclusively work with one another in the field of epigenetics, allowing scientists to openly share data and explore multiple targets, says Constellation CEO Mark A. Goldsmith. The deal's structure was enabled, he says, by Constellation's agnostic approach to drug development: Whereas some epigenetics companies are focus...

In solution processed single layer white organic light emitting diode (WOLED) applications, the choice of host matrix and optimization of dopant levels represent two crucial parameters to consider. In this work, poly(N-vinylcarbazole) (PVK): 2-(4-Biphenylyl)-5-phenyl-1,3,4-oxadiazole (PBD) and PVK:1,3-bis[(4-tert-butylphenyl)-1,3,4-oxadiazolyl] phenylene (OXD-7) matrices are used as hosts for perylene based devices. PVK:PBD presented better compatibility and lower turn-on voltages compared to PVK:OXD-7. Benefiting from the exciplex emission observed at 630 nm, a color rendering index (CRI) value of 90 is reached with the device containing PVK:PBD as the host and 0.1 wt.% of an orange emitting perylene derivative, i.e., PDI. Introduction of the perylene based green emitter, i.e., PTE, in this emitting layer not only caused a fading in the exciplex emission, but also resulted in disappearance of the electroplex peak at 535 nm, which is detected between PVK:PBD and PTE in bare PTE containing devices. Full visible range coverage is achieved by optimizing the PDI:PTE ratio. WOLED containing PVK:PBD:0.06 wt.% PDI:0.03 wt.% PTE presented high CRI (≥95) and adjustable correlated color temperatures (CCT, 3800 K-5100 K).

Objective
To analyze influencing factors of low-dose aspirin on pre-eclampsia (PE) in gravidae with abnormal uterine artery blood flow spectrum.

Methods
From February 2013 to December 2014, a total of 90 gravidae with abnormal uterine artery blood flow spectrum were enrolled into this study. They were divided into 2 groups, study group (n=45) and control group (n=45) according to whether taking low-dose aspirin or not. Clinic data between two groups were retrospectively analyzed and multivariate unconditional logistic regression analysis was conducted to explore the influencing factors of low-dose aspirin on PE in gravidae with abnormal uterine artery blood flow spectrum. ① The clinical data, including constituent ratio of age, age, body mass index (BMI), gestational age at delivery, proportion of hypertension and diabetes mellitus history, constituent ratio of modes of delivery, diastolic pressure, systolic pressure blood pressure and 24 h urinary protein quantitation during first trimester of gravidae between two groups, ass well as constituent ratio of neonatal gender and birth weight of infants between two groups, were compared. ② The diastolic pressure, systolic pressure and 24 h urinary protein quantitation during second and third trimester between two groups were detected and compared. ③ Univariate analysis was conducted on the clinical data between gravidae with PE and gravidae without PE. Based on the results of existing studies, clinical experience and univariate analysis results, multivariate unconditional logistic regression analysis were conducted about low-dose aspirin on PE in gravidae with abnormal uterine artery blood flow spectrum. The procedures followed in this study were in line with the ethical standards set by Ethical Review Board of Investigation in Human Beings of Yan′an University Affiliated Hospital and were approved by the committee. The study obtained the informed consent of each subject, and signed a clinical research informed consent with each subject.

Results
① There were no significant differences between two groups in the aspects of constituent ratio of age, age, BMI, gestational age at delivery, proportion of hypertension and diabetes mellitus history, constituent ratio of modes of delivery, diastolic pressure, systolic pressure and 24 h urinary protein quantitation during first trimester, as well as constituent ratio of neonatal gender and birth weight of infants (P>0.05). ② The diastolic pressure, systolic pressure and 24 h urinary protein quantitation during second and third trimester in study group were all lower than those of control group (second trimester: t=2.144, P=0.012; t=5.632, P=0.009; t=10.310, P<0.001; third trimester: t=14.680, P<0.001; t=20.431, P<0.001; t=106.21, P<0.001). ③ The incidence of PE in study group was 6.7% (3/45), which was lower than that of 44.4% (20/45) in control group (χ2=5.780, P=0.003). ④ The univariate analysis showed the following results, there were significant differences between gravidae with PE and gravidae without PE in the aspects of constituent ratio of age, proportion of hypertension history and constituent ratio of neonatal gender (χ2=6.317, P=0.012; χ2=7.220, P=0.007; χ2=5.332, P=0.021). Furthermore, multivariate unconditional logistic regression analysis showed that, low-dose aspirin (OR=0.015, 95%CI: 0.002-0.248, P=0.005) and female gender (OR=0.131, 95%CI: 0.014-0.649, P=0.016) were the independent protective factors, and age under 20-year-old (OR=6.767, 95%CI: 3.418-7.084, P=0.024) and age over 40-year-old (OR=3.360, 95%CI: 1.849-5.051, P=0.044) were the independent risk factors of PE in gravidae with abnormal uterine artery blood flow spectrum.

Conclusions
Low-dose aspirin can be used as one of the options for gravidae with abnormal uterine artery blood flow to prevent PE in clinic, especially for the age under 20-year-old and over 40-year-old.

Abstract Froth flotation is an important process for separating metal particles from gangue. A single flotation circuit for copper uses approx. 44 billion litres water a year. In situ process monitoring of the foam's parameters and closed-loop control can reduce the resource use. However, no measurement technique is broadly employed that yields the liquid fraction distribution in the froth. Optical measurements are prevented by the bulk foam's opacity. Though, ultrasound in the low frequency range is able to penetrate froth. In this paper we investigate the application of ultrasound to measure the local liquid content of aqueous foam in the axis of the ultrasound beam. Assuming a dependency of the backscattering coefficient b on the foam's liquid fraction ϕ, we developed a model to calculate b from the echo signal. Local backscattering coefficients b n {b_{n}} can be determined for time gated windows and show a trend in the dependency on the foam's liquid fraction ϕ (for ϕ < 0.8\phi <0.8 %). The absolute uncertainty of the liquid fraction determined by means of an electrical reference measurement is σ ϕ = 0.079{\sigma _{\phi }}=0.079 %. We demonstrated the capability of spatio-temporally resolved measurements with a frame rate of 0.33 Hz and an axial resolution of 7.9 mm in an experiment with a time-varying, inhomogeneous liquid fraction.

There is a continuous Cenozoic sedimentary sequence in the Lantian-Weinan area in the southeastern Weihe Basin, whichcontains a large number of mammal fossils. The Bahe Formation is especially famous for the three-toed equid "Hipparion" and theother mammal fossils, and it has been accordingly established as a standard of Bahe stage. However, there are still debates about theage of the Bahe Formation. In order to investigate the importance of the Bahe Formation and its sedimentary environmental changes andpaleontological characteristics in the Late Neogene period in Northern China, we carried out a detailed magnetostratigraphic study ofthe type Bahe Formation called the Duanjiapo section(246 m thick), which is located on the southern bank of the Ba River, LantianCounty, Shaanxi Province. The magnetic polarity sequence can be clearly calibrated to the Geomagnetic Polarity Time Scale(GPTS).The result shows that the age of the Bahe Formation is 11~7 Ma, corresponding to the Late Miocene. This study believes that the BaheAge should be a separate stratigraphic unit that is different from the Baode Age. It could provide a more precise age for the regionalmammal fossils comparison. Meanwhile, the Bahe Age is also different from the Lantian Age, according to the comparison ofsedimentary environment and paleoclimate with other basins, i.e. the Linxia Basin and the Tianshui Basin. The Bahe Age ischaracterized by a much drier semiarid steppe climate whereas the Lantian Age is humid forest climate.


Why should economists be concerned with feminism? According to Julie Nelson, the answer is to do better research. In this book, she makes the case that economists' attraction to (or even obsession with) abstraction, formalism, and rationality may result in elegant mathematical models but can leave us lacking in understanding of real-world economic problems like poverty, inequality, and discrimination. Feminist principles, Nelson argues, bring relevance and insight into the discipline by invoking a balance between formalism and the complexities of human behavior. For Nelson, adherence to traditional neoclassical concepts, including utility maximization, market equilibrium, and stable preferences, may, in certain circumstances, hinder our attempts to learn about the economic world. The popularity of these concepts is related to how easily they can be used to fit social and economic phenomena into mathematically tractable formulas. However, the tidy explanations that result often disregard potentially crucial non-self-interested motives like caring and dependency, which could significantly alter descriptions of and solutions to economic problems. While Nelson is not against using mathematical methods or abstraction where appropriate, she strongly asserts that for some questions other methods may be more suitable. An alternative feminist economics approach to the family, Nelson argues, would acknowledge that intrafamily power relationships, intrafamily antagonisms, and the caring relationships between family members could lead to non-utility-maximizing traits such as economic responsibility and altruism. The author takes care to distinguish those two dynamics, both of which are missing from standard neoclassical economic models: "Altruism describes a case where I might act in ways that benefit you, because your welfare or your consumption are arguments in my utility function.... Responsibility as opposed to altruism means that actions may be taken quite apart from personal preference" (p. 70). Nelson observes that what is left out of economics often has to do with women and women's work. She asks, "Is it only coincidence that when economics moved away from sociology the latter was considered by some to be made up of 'leftovers: Marriage, the family, poverty, crime, education, religion, sex'-including exactly those areas of women's traditional activity and realms of pressing social problems?" (p. 57; quoted from Mary 0. Furner, Advocacy and Objectivity [Lexington: University Press of Kentucky 1975], p. 298). The abandonment of things considered feminine, including women themselves, scarcely accords with the economic profession's self-image as objective and valuefree, Nelson argues, and feminism can only strengthen economics by bringing these forgotten pieces back into the theoretical fold. Nelson uses feminist theories of culture to explain why concepts, behaviors, and metaphors associated with women have been left out of neoclassical economics. Her argument revolves around gender metaphors and hierarchies in our language and culture. Drawing from research in linguistics, cognition, philosophy, and rhetoric, Nelson explains how gender is used to connect sex, which is biological, to other objects, things, or ideas. In the area of thinking, rationality is considered male while irrationality or emotion is considered female. In and of itself, this gender dualism is neither good nor bad, but Nelson views as sexist the hierarchical ranking of the male-associated metaphors over the female-associated metaphors. Neoclassical economic concepts and ways of thinking are considered good because they are associated with male traits, while other methods and ideas are considered inferior because they are female-associated. The result, Nelson argues, is economists' adherence to an often limiting economic method. Nelson suggests specific changes to achieve more balance in economic research between supposedly masculine and supposedly feminine perspectives. In discrimination research, for example, she encourages supplementing econometrics with expanded use of oral histories,


We propose a joint Source-Based Analysis (jSBA) framework to identify brain structural variations in patients with Major Depressive Disorder (MDD). In this framework, features representing position, orientation and size (i.e. pose), shape, and local tissue composition are extracted. Subsequently, simultaneous analysis of these features within a joint analysis method is performed to generate the basis sources that show signi cant di erences between subjects with MDD and those in healthy control. Moreover, in a cross-validation leave- one-out experiment, we use a Fisher Linear Discriminant (FLD) classi er to identify individuals within the MDD group. Results show that we can classify the MDD subjects with an accuracy of 76% solely based on the information gathered from the joint analysis of pose, shape, and tissue composition in multiple brain structures.


THE PHYSICAL CONDITION OF SCHOOL CHILDREN. THE Social Inquiry Committee of the Dundee Social Union has recently issued a report on the physical condition of the school children.' The inquiry was planned in consultation with Dr. Leslie Mackenzie and other experts, and superintended by Miss Mona Wilson. One thousand children in all were examined. To avoid opposition, the children examined were not stripped, and the doctors could only investigate the upper part of the body. Hence the amount of disease is understated; and yet in some of the schools such results appear as 17 casesof disease among i8 infants, 9i cases among 99 boys, 107 among io8. Nearly I per cent. of the boys, exclusive of the defective, are put down as " dull." The worst case is that of Cowgate School, with nearly I9 per cent. of dull and defective boys against nearly 7 per cent. in the best, girls seeming to bear adverse-conditions better than boys, as their death-rates show. The investigators give particulars of the physical condition of the dull and defective children, showing that out of 96 children -only seven were not in some way diseased or defective in body. Large numbers of the dull children suffered from bad sight and hearing, 65 of them from defect or disease of the eyes (mostly long sight, simply requiring spectacles), and 42 from deafness in a greater or less degree, while 25 had adenoids. In the matter of defective eyesight alone the medical officer calculates that nearly 7,000 children in Dundee are seriously hampered in their education. It may be gathered that the Dundee School Board does not give enough attention to ventilation and lighting, or to guarding against the children's getting overheated by sitting in their outdoor clothes. Their arrangements for the elder children who go to work as half-timers or whole-timers are also unsatisfactory. The half-timers are taught on the alternate-day system, which is much more tiring than the usual half-day method. The children who are completely exempted from the day school are usually obliged to attend evening schools for two hours on four evenings in the week, No fewer than I6.7 per cent. of the children are verminous, and among the younger ones who cannot look after themselves the proportion would be much larger. Apart from minor troubles which could be dealt with by nurses, the large amount of serious disease shows that there is also undeniable need for periodical examination by a doctor. Dr. Emily Thompson found 20 cases (among 532 girls) in which the apex of one or other lung was affected. The cases of heart disease amounted to 7.47 per cent., or about 1,500 children for the whole of Dundee; for the discovery and treatment of these cases there is no provision, while the school exercises may do them serious injury. The prime necessity appears to be good food. The measurements and state of nutrition add the testimony of Dundee to the case for school feeding. The Dundee elementary school child is at all ages between 5 and I3 shorter and lighter than the child of a secondary school in the town and than the average given by Mr. F. Galton, and three-quarters of the boys of 13 were distinctly below the Galton average for the artisan class.. The measurements of infants born at the Dundee Hospital show that this is not due to any original inferiority of the Dundee boy, for boy-babies start well, being taller than the average and not seriously less in weight. The classification as to nutrition also shows a low condition. Some schools are much worse than others, but the average shows 30 per cent. fat, 58 medium, and 12 thin among the boys, one school having over i8 per cent. among the thin. The girls run less to extremes, So per cent. of them being in a "medium" state. Not half the children of either sex have a good "health appearance."

The number of roundabout type intersection treatments in Victoria has increased from less than 200 in 1978 to over 400 in 1980 and this form of control has received a wide acceptance from all sections of the community. The installation of a roundabout can achieve substantial improvements in terms of intersection performance particularly in the area of vehicle to vehicle accidents. This paper reviews the accident patterns of a sample of roundabouts and compares the after experience with the before situation. An assessment is also made of the operational characteristics and design standards used a teach roundabout to determine the effect of alternative layouts and beautification treatments. The study shows that roundabouts are an effective method of reducing the incidence and severity of right angle accidents at intersections; however proper consideration at the design stage is necessary in order that single vehicle accident type incidents are not increased. It is also concluded that the time distribution of accidents at roundabouts is significant as a high proportion of reported accidents occur during the hours of darkness. A review is also provided of existing design guidelines for roundabouts.


Introduction: The recent advance in imaging of Mars confirmed that a number of previously hypothesized geomorphological feature types were related to ice flow, as well as revealed a variety of related new feature types. In the equatorial zone, the western slopes of the four major volcanoes bear a set of features interpreted as left by kilometers-thick cold-based ice sheets formed during epochs of high mean obliquity in the Amazonian [e.g., 1]. Martian midlatitudes display a very wide variety of features related to flow of ice or creep of permafrost; they include lobate debris aprons, lineated valley fill, slope-associated lobes interpreted as extinct or present rock and/or debris-covered glaciers, extinct ice sheets, etc. The abundance of such features in the midlatitudes is explained [2] by both relatively high year-average temperature, which enables flow of H2O ice or icy permafrost, and relatively good conditions for ice stability. At high latitudes, H2O ice is present in large amounts, forming the polar layered deposits (PLD) and the high-latitude ice-rich mantle, but ice flow is very limited. In general, this is naturally explained by the much lower year-average temperature at high latitudes. Here we describe very unusual deposits that depart from this general trend, and discuss their possible origin. Unusual extinct small cold-based glaciers: An unusual series of narrow ridges with lobate planforms occurs at high latitudes in the martian arctic (74°N 96°E), in association with the westand northwestfacing steep slopes of a PLD outlier (Fig. 1). The most striking aspect of these features is the large number of distinctive arch-like ridges (in planform view) forming more than 20 parallel and overlapping loops over a distance of about 75 km grouping in three sets with gaps between them (Fig. 1b). The individual ridges making up the loops are 15-80 m wide, are generally continuous, and show little width and height variation along their strike. The loops formed by these ridges are most typically 5-7 km in long axis, and ~1.5-3 km wide. No impact craters could be found that were clearly superposed on top of the ridges; in several cases, the ridges in the distal parts of loops are superposed on the extended deposits surrounding impact craters; no evidence of modification of the underlying deposits or structures are observed; these all suggest a relatively youthful age. High-resolution MOC images (E03/01183, R02/01333) show that the ridges are mantled and covered with typical high-latitude polygonal pattern uniformly with their surroundings. Some of the ridges, and thus the loops, are superposed on one another. In the middle group (Fig. 1c, top) a generally continuous ridge set that extends distally (with respect to the PLD outlier) for a distance of up to 15 km; the ridge is subdued in some places along its strike. Shorter loops contained within this deposit are clearly superposed on this larger ridge complex occurrence. Stratigraphic relationships for the middle group suggest that the earliest set of ridges was the broadest and reached the greatest distal limits; an intermediate set extended only about 3 km, and the latest set extended an intermediate distance. In the southern group, local stratigraphic relationships also support three stages. The proximal parts of the looped ridges are open toward the steep wall of the PLD outlier and are separated from it by a 10-20 km wide gap.


Abstract We assembled and annotated the complete mitochondrial genome of Drechslerella brochopaga. This mitogenome is a closed circular molecule of 193,195 bp in length with a GC content of 26%, including 14 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and 2 ribosomal RNA (rRNA) genes. We analyzed the phylogenetic relationship between D. brochopaga and other 26 ascomycetes using the 14 annotated protein-coding genes of the mitochondrial genomes.

It is not the essence to judge the standard of food security by market price. In order to adapt to the new phase of food development in China, we should transfer the focus of ensuring food security to the improvement of comprehensive production ability. Since the idea of self-supply food security can no longer do, we must establish the food security on the basis of regional trade division. To realize the target of food security, it is the fundamental guarantee to establish a long-run effective mechanism for farmers to increase their income incessantly.


The formation of defects during the initial stages of native-oxide growth on the GaSb (001)-α(4 × 3) surface has been studied computationally using spin-unrestricted density functional theory. It is found that insertion into a Ga-Sb adatom dimer to form a peroxo Ga-O-O-Sb bridge is the most energetically favorable process with insertion into Ga-Sb back-bonds being somewhat less so. A Ga-O-O-Ga bridge between dimers is also favorable, but Sb-O-O-Sb bridges show little if any stability. In the course of analyzing molecular adsorption, a particularly reactive site has been identified that leads to O2 dissociation with little or no barrier. This process is initiated in the vicinity of an Sb-Sb dimer in the terminating layer and leads to sub-surface Ga and Sb defect sites (i.e., coordinatively unsaturated atoms) and to strained Ga-Sb bonds that may be susceptible to further O2 attack. However, the defects formed in these reactions do not produce states in the gap.


For Tram cars, it is often necessary to operate in cities on strongly curved track, which is followed by an increased effect of the vehicle on the track. Especially, this increased effect occurs in spiral transition curves situated between direct and arc sections or between two arc sections of different radius. In such case, increased guiding forces, creep in the rail - wheel contact, wear and noise generation can be observed. Exactly with the aim to reduce these undesirable effects we designed a tram bogie with steered wheelsets. This paper deals with a modification of its coupling to vehicle body in order to improve vehicle dynamics in transition curves. Proposed innovative construction of this coupling unit is registered by authors under Utility Model Nr. u201609015 and Utility Model Nr. u201703246. Description of the proposed way for a vehicle to pass through curved track with regard to bogie-body coupling and wheelset steering mechanisms with usage of multibody computing software is given in this paper.


Currently existing regulatory documents assume that refrigeration compressors are tested as part of test rigs with heat-exchange equipment. Given the high energy intensity of centrifugal compressors, the drive power of which in cooling mode with a cold capacity of up to 8.0 MW can be 2.0 or more MW, the creation of test rigs for preliminary and acceptance tests at the manufacturer's factory requires a large investment. An alternative to the considered refrigeration centrifugal compressors test method is a test on a test rig in which the agent is partially condensed. In this case, an evaporator and a full-sized condenser are not required. The mathematical model of the refrigeration centrifugal compressors developed by JSC VNIIKHOLODMASH, allows testing of the refrigeration centrifugal compressors in model conditions, when the entire compressor operation cycle at the test rig is carried out in the area of superheated steam. Since the refrigeration centrifugal compressors mathematical model is based on physical simulation of compression processes in model stages at different values of conditional Mach numbers, dimensionless characteristics of model stages can be used to calculate the characteristic of the created compressor when operating under new conditions. The implementation of the model test method provides reduction of testing time due to absence of phase changes of the agent, improves the accuracy of the obtained results, reduces of power consumption, simplifies the test rig, and reduces consumption of the agent for filling the rig and water for cooling the agent.


The smart metering impact assessment investigates the costs and benefits of different smart metering rollout scenarios for Switzerland during the period 2015-2035. It is based on the evaluation of smart metering pilot projects and 30 interviews with representatives from aca-demia, industry, and government. Next to the direct and indirect costs and benefits of smart metering, the study assesses the economic and ecologic effects of the investigated scenari-os. The interdisciplinary project team applied several simulation-based models to calculate these various effects.
The impact assessment concludes that the benefits of a nationwide smart metering rollout outweigh the costs. Even though the smart metering equipment and its installation cause ad-ditional costs of one billion CHF (compared to the costs of maintaining the existing metering infrastructure), a full rollout leads to an energy consumption reduction worth 1.5 to 2.5 billion CHF. The study shows that the large load shifting potential in Switzerland only leads to small economic benefits, while the small consumption reduction potential leads to large benefits. Customers (households, services and industry) are the major benefactors of a smart meter-ing rollout. For network operators and energy suppliers, however, the associated costs are higher than the expected benefits. Additionally, smart metering leads to slightly positive im-pulses for the economy. The stimulation of competition amongst energy related products and services, the avoided external generation costs, and the importance of smart metering for Switzerland's energy strategy 2050 advocate for a nationwide rollout of smart metering.


Objective To investigate the mechanisms of the ginseng polysaccharide(GPS) on the apoptosis of leukemia K562 cells.Methods The K562 cells at logarithmic growth phase were divided into control and GPS groups.The cells in the control group were normally treated and cells in GPS group were incubated with 0.4 g/L GPS.Flow cytometry and Hoechst 33258 staining were used to demonstrate the apoptotic changes in the two groups after incubation for 48 h.Gene expression of p38 and JNK were detected by RT-PCR.The immunofluorescence staining was used to detect the activation of Caspase-3 and expression of p-p38 and p-JNK protein.The changes of p38,JNK,p-p38,p-JNK,and cleaved Caspase-3 protein were detected by Western blotting.Results Compared with the control group,the apoptosis rate of K562 cells in GPS group was significantly increased(P 0.05).After the treatment with GPS,chromatin condensation was observed when the cells were stained by Hochest 33258.The expression of p38 mRNA and JNK mRNA was obviously increased.The immunofluorescence staining results showed that the expression of p-p38,p-JNK,and cleaved Caspase-3 proteins was significantly increased in GPS group and obviously transferred to the nucleus.The Western blotting results showed that there was no significant change in total p38 and JNK protein(P 0.05),but an increasing trend in p-p38,p-JNK,and cleaved Caspase-3 was observed(P 0.05).Conclusion GPS could induce K562 cell apoptosis and the effect may be achieved through MAPK signal transduction pathway.
