The aim of this article is to present the results of a comparative study of four di2erent types of solar wall. These results have been obtained using a numerical simulation model. In order to validate the model, an extensive experimental study has been conducted on a composite solar wall. The 5rst part of the article is devoted to the particular features of the four solar wall con5gurations, followed by a description of the experimental installation, the measurements and study of the various modes of thermal transfer necessary for the model to be validated. The third section begins with a brief presentation of the principle used to develop this model, continuing with the validation phase. The model is then used to study the energy e6ciency of solar walls in di2erent locations and under di2erent climatic conditions. This is followed by an analysis of the way in which they release the energy supply, and their performance during the summer period. The results of this study are fundamental in helping architects or project managers to choose the best suited con5guration for each type of building. c © 2001 Elsevier Science Ltd.

Multimodal machine learning is an emerging area of research, which has received a great deal of scholarly attention in recent years. Up to now, there are few studies on multimodal conversational emotion recognition. Since Graph Neural Networks (GNNs) possess the powerful capacity of relational modeling, they have an inherent advantage in the field of multimodal learning. GNNs leverage the graph constructed from multimodal data to perform intra- and inter-modal information interaction, which effectively facilitates the integration and complementation of multimodal data. In this work, we propose a novel Graph network based Multimodal Fusion Technique (GraphMFT) for emotion recognition in conversation. Multimodal data can be modeled as a graph, where each data object is regarded as a node, and both intra- and inter-modal dependencies existing between data objects can be regarded as edges. GraphMFT utilizes multiple improved graph attention networks to capture intra-modal contextual information and inter-modal complementary information. In addition, the proposed GraphMFT attempts to address the challenges of existing graph-based multimodal Emotion Recognition in Conversation (ERC) models such as MMGCN. Empirical results on two public multimodal datasets reveal that our model outperforms the State-Of-The-Art (SOTA) approaches with the accuracy of 67.90% and 61.30%.


We study the interaction of two counter-propagating electromagnetic waves in vacuum in the Born-Infeld electrodynamics. First we investigate the Born case for linearly polarized beams, ${\bf E}\cdot{\bf B}=0$, i. e. $\mathfrak{G}^2=0$ (crossed field configuration), which is identical for Born-Infeld and Born electrodynamics; subsequently we study the general Born--Infeld case for beams which are nonlinearly polarized, $\mathfrak{G}^2\neq0$. In both cases, we show that the nonlinear field equations decouple using self-similar solutions and investigate the shock wave formation. We show that the only nonlinear solutions are exceptional travelling wave solutions which propagate with constant speed and which do not turn into shocks. In the Born case, we naturally obtain exceptional wave solutions for counter-propagating (real photon-photon scattering) and for a co-propagating (non-interacting) beam orientation we investigate their direction of propagation. In the Born--Infeld case, we have additionally chosen the solutions which have constant phase velocities to match the limits of phase velocities of the background field in the Born case. We obtain two types of exceptional wave solutions, then we numerically analyze which phase velocities correspond to the counter- or co-propagating beams and subsequently we determine the direction of propagation of the exceptional waves.


The hydrogenation of ethylene, ethylene‐d4 and partially deuterized ethylene photosensitized by excited mercury to λ = 2537A has been studied. It has been found that the rate of hydrogenation of the deutero‐compound is more rapid than that of ethylene under comparable conditions. With excess hydrogen, the rate is independent of the ethylene pressure. The data obtained indicate that butane is the important product together with small amounts of ethane relatively more abundant in the case of ethylene‐d4. Negligible amounts of methane are formed. The suggested mechanism involves the reactions H+C2H4 = C2H5 followed by C2H5+C2H5 = C4H10 and to a lesser degree, C2H5+C2H5 = C2H6+C2H4. At low hydrogen concentrations, or in absence of hydrogen, a photosensitized polymerization occurs, faster with ethylene than with ethylene‐d4. The slower rate of polymerization of the deutero‐compound may be explained on the basis of zero‐point energy differences between C2H4 and C2D4 in their reactions with free radicals to yiel...


Aging effects degrade circuit performance with time, inducing reliability problem. Accurate prediction of circuit aging can help designer determine the reasonable design margin, avoiding the over-design of the circuit. Based on the physical understanding of aging mechanism, an analysis framework is proposed to predict NBTI-induced circuit aging. The analysis framework starts at the worst case prediction, which assumes the extremely operational conditions. Then, the impacts of different workloads and logic topology of the circuit on the aging-induced degradation are incorporated into the analysis framework to make the predicted result be closer to the practical scenario. Experimental results demonstrate that the effectiveness of the proposed analysis framework.


ABSTRACT The Central-hall house was brought into the American West by Mormons, members of the Church of Jesus Christ of Latter-day Saints. This house type has two basic floor plans, the narrow "I" and the wider "Four over Four" types. The Central-hall plan has a rich folklore in Mormon Country. Although some "Gentiles" built this type, it was generally outmoded by the time the West was opening up. Gentile settlements were dominated by Victorian and other stylistic influences which the Mormons rejected for religious and cultural reasons. The Central-hall house, along with other cultural elements, is helpful in detecting areas of the West settled by the Mormons.


An increased frequency of scabies was reported from a few European1,2 , Asian3 , and African4 countries between 2012 and 2018. We performed a retrospective database search in two tertiary-level dermatology centers in Istanbul about the frequency of scabies diagnosis between January 2016 and December 2019.


Objective: To explore the possible mechanism of Erzhi Pill in the treatment of breast cancer based on network pharmacology. Methods: Through systematic pharmacology database and analysis platform of Traditional Chinese medicine (TCMSP) and literature review, the candidate active ingredients and corresponding targets of Erzhi Pill were retrieved and collected. The UniProt database and the Human Genome Annotation Database (Genecards) were used to compare the results, and the potential target genes were obtained for the coincidence of Erzhi Pill and breast cancer. Cytoscape was used to construct the "candidate component - action target" network of Erzhi Pill. Generate Style from Statistics tool in String database and Cytoscape software was combined to construct protein interaction network.The Kyoto Encyclopedia of Genes and Genomics (KEGG) pathway enrichment analysis and GO classification enrichment analysis for targets of Erzhi Pill were conducted using the Database for Annotation, Visualization and Integrated Discovery (DAVID ) bioinformation resource Database. Results: A total of 21 candidate active components, including Beta-sitosterol, Quercetin, Luteolin, Demethylwedelolactone, Kaempferol and so on, were screened from Erzhi Pill, corresponding to 158 target genes, including vascular endothelial growth factor (VEGF), amino-terminal kinase (C-Jun), proto-oncogene (C-MYC), matrix metalloproteinase-9 (MMP-9), and mainly involved in TNF-α, phosphatidylinositol-3-kinase/protein kinase B(PI3K/Akt), tumor suppressor gene p53, toll-like receptor family and other signaling pathways. Conclusion: This study predicted the possible mechanism of action of Erzhi Pill in the treatment of breast cancer based on the method of network pharmacology, and provided a direction for further research.


In this paper observability of single passive observer for target motion slate estimation is discussed. Passive observation systems are divided into bearing, time of arrival, Doppler, bearing and time of arrival, bearing and Doppler observation systems. For every type of systems, observability is analyzed in common observation model. The approximate equivalent relation in systems between time difference of arrival and Doppler is shown by comparing their observability degrees.


In view of the shortages of the point contact synthesis methods being difficulty and complex on the determination of machine-tool generating settings of spiral bevel gears, it is presented a method of ease-off surface synthesis reaching the goal of pre-controlling contact performance based on the integrity of contact pattern. From the view of differential geometry, the definition on the 2nd order osculating surface and the study on its topologic method have been done. Under the precise of 2nd order differential surface, the osculating surface is exactly same as the original curve surface in the differential geometric performance, thus it is able to take place of that geometric analysis of original curve surface. Based on the generating model of spiral bevel gears, the construction of ease-off flank of conjugate surfaces of tooth is carried out. Then the study of topologic method on contact pattern of tooth surface is done by using the osculating surface of the ease-off flank. The determination of contact parameters of the pinion is done by the controllable parameters synthesis of contact pattern. After that the computation of machine-tool generating settings of the pinion is performed by the numerical optimal method. By using the ease-off osculating surface the tooth meshing simulation is carried out, which presents perfectly the behavior of tooth contact such as the size and shape of contact pattern, the orientation of contact path and the parabolic curve of transmission errors of tooth surfaces. This presented method is not only more suitable to the numerical computation, but also able to pro-control the behavior of tooth contact and provide the perfect information of tooth contact.


Herbicides are the chemicals used to control weeds in crop plants. Low concentration of herbicide helps to increase the growth of plant whereas high concentration affects the growth of plant as it destroys microbes present in the soil and affects different photosystems and ultimately photosynthesis


(including the self-employed) comply with the Control of Substances Hazardous to Health Regulations 2002 (COSHH), as amended, to control exposure to metal and casting fume and protect workers' health. It is also useful for trade union safety representatives. This sheet describes good practice using general ventilation. It covers the points you need to follow to reduce exposure to an adequate level. It is important to follow all the points, or use equally effective measures. Molten metal fume (foundry fume) is hazardous to health. Ferrous foundry fume can cause lung cancer. Casting fume is irritating to breathe. I Keep exposure to fume as low as possible.


A photosensitive self-assembled monolayer (SAM) is selectively irradiated to fabricate a pattern on an Au electrode, and a thin film of aniline or 3-methylthiophene is deposited on it by electropolymerization. Adhesion of the polymer films can be controlled by the monolayer terminal group. Applying tape to the sample and peeling it away selectively removes the conducting polymer film to the tape in a near-micron resolution pattern.


The nonlinear coupling between whistler and ion-acoustic modes in a plasma having bi-Maxwellian distributed electrons is considered. For stationary propagation, the coupled waves lead to a novel nonlinear structure which has a triple-hump profile for the whistler field intensity. In the critical parameter regime (A = 3), only supersonic propagation of the coupled modes is allowed. In other regimes, three integrable cases of the coupled mode propagation have been identified. @ 1998 Elsevier Science B.V. PACS: 52.35.M~; 03.40.Kf


It has been estimated that more than half of the world's population are bilingual (Baker, 2007; Bialystok, 2001). As educational psychologists (EPs), it is important that we have a sufficiently deep knowledge and understanding of bilingualism and how this may have an impact on our practice. This paper will consider some of the principal advantages and disadvantages of being bilingual as represented in the literature. It is argued that EPs should be aware of such issues when working with bilingual children, as well as having an understanding of the cultural richness of their backgrounds, and how that may potentially have an impact on their learning, both positively and negatively. The paper will discuss the need for calibration and sensitivity when undertaking assessment work, for example, standardised cognitive assessment, and will examine some of the practical implications of working with bilingual children. Finally, the paper will consider issues surrounding bilingual children who have specific additional support needs, namely children with dyslexic-type difficulties and those on the autistic spectrum, as well as children with learning difficulties.


The paper explored the impact of applying the time driven activity-based costing-TDABC- model (independent variables) on improving the efficiency of performance (dependent variables) in Jordanian industrial corporations. Based on a questionnaire form data from a sample of 73 participants at different managerial positions, from 30 industrial corporations listed in Amman stock exchange (ASE), were gathered and processed using the statistical package of social sciences. The main results showed that there are significant impacts of applying TDABC on improving the efficiency of performance in Jordanian industrial corporations. The main conclusion indicated that TDABC has the ability to benefit from technological developments on the basis of the activities' charts and reflected on pricing decision making processes in industrial corporations. The research also concluded that senior management and cost accountants of the sample studied did not desire in the short run to change the current cost accounting system due to the additional costs of using the new cost accounting system. The study recommended the application of TDABC in corporations where their operations relied on TDABC's constituents as proved its impact on reducing costs of products and increasing corporations profitability.


Abstract Context. Wild dogs, including dingoes and dingo cross-breeds, are vertebrate pests when they cause financial losses and emotional costs by harming livestock or pets, threaten human safety or endanger native fauna. Tools for lethal management of these animals currently include aerial baiting with poisoned baits. In New South Wales (NSW), Australia, aerial baiting was previously permitted at a rate of 40 baits km−1 but a maximum rate of 10 baits km−1 was subsequently prescribed by the Australian Pesticides and Veterinary Medicines Authority. The efficacy of these baiting rates has not been quantified in eastern Australia, undermining the value of the policy and rendering adaptive management efforts difficult, at best. Aim. To quantify the mortality rate of wild dogs exposed to aerial baiting at historic and currently approved rates, i.e. 40 baits per kilometre and 10 baits per kilometre, respectively. Methods. Wild dog mortality rates were measured at sites in mesic north-eastern NSW, where aerial baiting was applied to control wild dogs and contrasted with sites and individuals where no baiting was undertaken. In total, 132 wild dogs were trapped and fitted with GPS-VHF telemetry collars before annual aerial baiting programs. Collars were used to locate animals after aerial baiting and to determine the fates of individuals. Key results. 90.6% of collared wild dogs exposed to aerial baiting at 40 baits km−1 died, whereas only 55.3% of those exposed to 10 baits km−1 died (Welsh's t = 4.478, P = 0.004, v = 6.95). All wild dogs that were not exposed to toxic baits survived during the same periods. Conclusion. Managers using aerial baiting to maximise wild dog mortality in mesic south-eastern Australia should use 40 baits km−1 rather than 10 baits km−1. Implications. Wild dog population reduction for mitigation of livestock and faunal predation requires the application of efficacious control. The currently prescribed maximum aerial baiting rate of 10 baits km−1 is inadequate for controlling wild dog populations in mesic forest environments in NSW.


The article reports the results of a study on the formation of independence in older preschool children by means of animation. The content of the concepts of "preschoolers' independence" and its structural components is revealed. The potential of animated films in the formation of independence in 5-7-year-old children is demonstrated. The authors describe an experimental study focusing on the implementation of a specially developed program "Cartoons about the most important" aimed at the formation of all structural components of independence in older preschoolers.


The effect of severe plastic deformation at ambient temperature on microstructures and mechanical properties of aluminum alloy 2519 was investigated by means of tensile test, micro-hardness test, optical microscopy and scanning electron microscopy. The results showed that tensile strength of as-queched 2519 alloy was greatly enhanced to nearly 550MPa (ultimate tensile strength, UTS) and 520MPa (yield strength, YS) by severe cold rolling or equal channel angular processing (ECAP) while the elongation decreased to 5%. The 2519 alloy could obtain quite well mechanical properties as much as 80 % and 12 passes cold rolling deformation. This indicated that pre-deformation by ECAP is effective in improving the mechanical properties of 2519 alloy by grain refinement, strain aging and high density dislocations.

Endothelin (ET) is a potent vasoconstrictive peptide synthesised by endothelial cells from which it is presumably released into circulation (Yanagisawa, Kurihara, Kimura, Tomobe, Kobayashi, Mitsui, Yazaki, Goto and Masaki 1988). ET is primarily a locally acting agent, and since its plasma concentration is very low, it is unlikely to be considered a circulating hormone {Masaki and Yanagisawa 1992). However, the level of endothelin-1 (ET-1), the major molecular form of ET present in human plasma, may be useful as a marker for endothelial synthesis of the peptide (Haynes and Webb 1992). ET could accelerate the vascular smooth-muscle proliferation over a longer time, leading to vascular lesions (Leppaluoto and Ruskoaho 1992). In view of these findings, it is reasonable to assess the activity of ET system in insulindependent diabetes mellitus (IDDM), where the incidence of specific microvascular complications (nephropathy and retinopathy) is much higher. Hence, it is the purpose of this study to find out whether or not plasma ET levels may undergo changes in IDDM patients, with or without microvascular complications.


New sub-surface challenges are encountered everyday as the industry drills more in complex geological and operational settings; and smarter applications are being made with new and more efficient technologies for real-time solutions. And, one of the remaining frontiers, that of real-time, high-quality, multi-applications borehole images while drilling with oil-base mud (OBM) has been overcome with deployment of multi-sensor, multi-physics measurements providing the highest resolution data. A new feature-based compression technology is developed to transmit the geological feature-rich data in real-time, even with limited telemetry; enabling real-time decision making.
 Logging-while-drilling (LWD) imaging in OBM started from low-resolution density images with limited meaningful applications; even ultrasonic imaging introduced lately was not able to consistently unmask the geological information. Industry-first technology advances for borehole image acquisition in OBM were made possible with the deployment of ground-breaking integration of multi-sensor, multi-physics technologies of electromagnetics and ultrasonic on one small sub. Four operational frequencies of electromagnetic measurements are used for resistivity-imaging to cover a wide resistivity range in the sub-surface, whilst ultrasonic images are made at two frequencies to help optimize the imaging for varying standoff and rugosity during drilling. This enables feature identification of subtle variation in texture, structure, sedimentation and diagenesis style; most of the sedimentary structures imaged on the apparent resistivity images made from electromagnetic measurements whilst the drilling-related features manifesting themselves more visibly on ultrasonic images.
 Results of this technology are discussed with various examples acquired during the early deployment; examples showing the plethora of information available in real-time enabling drilling optimization to hydro-fracturing decisions. A comparison has also been made with established wireline technology for validation of the LWD images in some of the examples. With more applications being developed to integrate this data, this opens up new avenues for geosciences and drilling solutions while drilling.
 This new technology overcomes the OBM barrier for high-resolution imaging while drilling, and coupled with feature-rich data transmission in real-time enables real-time decision making.


This paper identifies the motives for selling convertible bonds with a higher‐than‐aver‐ age initial conversion premium, using a sample of 300 convertible debt issues carried out between 2004 and 2014 by manufacturing and service companies from the United States, Europe and Asia. Empirical analysis indicates that high premium convertibles are issued by strongly undervalued com‐ panies with poor financial performance, looking to increase their equity capital through the back‐ door, under more favorable conditions in comparison to the issuance of common stock. For this rea‐ son, convertibles designed in this way are likely to be perceived by firms as a delayed equity rather than a debt sweetener.


A sample of 61 healthy volunteers (mean age = 65 years) participated in a study of the effect of lecithin on memory conducted by a gerontological social worker in collaboration with a physician specializing in neurological research. Forty-one subjects ingested 2 tablespoons of lecithin for 5 weeks whereas a control group of 20 subjects ingested a placebo for the same length of time. Memory function was established through a brief memory test and from a diary of memory lapses kept by the subject for 7 days prior to the experimental period and repeated during the 5th week. Analysis of the data found a significant improvement on memory test scores for the experimental group, which exceeded those obtained by the placebo group subjects. Participants receiving lecithin reported fewer memory lapses posttreatment than did the placebo subjects. Replication of the research with larger samples as well as an investigation of long-term effects, are recommended.


As living condition has been shown to affect rates of neurogenesis, the current study was designed to examine the relationship between neurogenesis and pain behavior, particularly stress-induced analgesia (SIA) and tonic pain. Mice received daily injection stress and were placed in group or isolated housing conditions, with or without access to a running wheel in order to differentially manipulate neurogenesis. Both males and females were used in this study to investigate sex differences involved. Animals were tested with hotplate and tail withdrawal tests before and after restraint stress to examine SIA (experiment 1), and with a subcutaneous formalin injection to assess changes in tonic pain—particularly in the late phase (experiment 2). Group housed runners were expected to have increased neurogenesis, decreased SIA and increased late phase formalin pain; however, findings did not support this hypothesis. In experiment 1, significant differences in overall acute pain were observed, depending on housing and running. In experiment 2, overall formalin pain behavior was influenced by housing, while running differentially influenced pain behaviors in each phase. Significant changes in neurogenesis were not observed, which-along with a number of confounding variables-may have influenced inconsistent findings.


These days, the Middle East remains one of the most explosive regions in the world. Today, Syria has become a kind of core of the global political crisis. This article inspects the political prerequisites for the emergence and development of the regional problem, reveals its features, and analyzes the external factors that have had and are still having an impact on the evolution of the Middle East problem. The article studies the preconditions for the growth of conflict potential and exacerbation of the struggle for influence in the Middle East. The role of Syria in the competition between the leading Arab countries and Iran for regional leadership is considered and conclusions are drawn about the goals pursued by them in the Middle East. The article examines the formation of Syria's foreign policy, analyzes the influence of the Palestinian factor on its regional policy, and reveals the position of Syria on the Lebanese problem. A number of factors influencing the evolution of Syria's foreign policy in the new geopolitical situation in the region are analyzed.


Agriculture is very important in everyday day life. Without agriculture we cannot satisfy our daily needs such as food. The process of developing the agriculture is very difficult as it depends on season, rainfall, water, soil, humidity etc. Rainfall is the important factor among this. Due to the changes of the season the rainfall is not constant, due to the lack of rainfall the farming land becomes dry and the irrigation of crops is very difficult for the farmers. This is the major problem in the agriculture. To overcome this in olden days the farmers used variety of irrigation systems for better crop production. Irrigation is nothing but watering the crops in cultivating land. The irrigations such as drip irrigation, springler irrigation, surface, subsurface irrigation are commonly used in many countries. These irrigation can perform a different characteristics and functions for a better crop production. Drip irrigation method was used in Israel by using the tubes and pipes. The springler irrigation method was used in Australia. These two irrigation system are now commonly used in India. In this irrigation the drop of water is send to crops but the water is insufficient and crops does not grow faster. Here we propose a new method of irrigation called center pivot irrigation system. The system is constructed in the center of farmland. It consists of sprinkler at the top and it sprinkles the water uniformly to all the crops. The crops get enough water and yield in a good manner. By using this method there is no water loss.


This thesis explores how to develop students' and teachers' awareness of intercultural concerns, and their sense of belonging to a modern, dynamic, multicultural community. The examination is preceded by a presentation about the relationship of language and culture. Then it specifies the elements of intercultural competence. It determines the way, how develop materials based on the intercultural aspect. Finally it compares an English course book written by a native speaker writer and another student's book with a Hungarian author. It shares experiences on how teachers can help students by pointing out major areas of culturally-influenced behaviour such as greeting or degrees of politeness to make their own culture explicit and to realise that other cultures might have different underlying values. Comparing the students' books I came to the conclusion how important of developing intercultural communicative competence in pupils.

Radiation grafted membranes offer several combined key benefits of PFSAs and hydrocarbon (HC) membranes. The synthesis involves the electron beam irradiatio n of a preformed polymer film, such as ETFE, followed by grafting of styrene or styrene derivatives, in many cases in combination with additional co-monomers, and subsequent sulfonation to obtain a proton conductin g membrane (Fig. 1). The use of low-cost materials an d processing steps offers the potential of producing lowcost membranes if fabricated on a reel-to-reel faci ity [1]. The flexible alkyl chains favor phase separation of the graft component from the hydrophobic, partially fluorinated backbone [2]. In addition, the membrane architecture can be designed in a wide parameter sp ace based on the choice of suitable co-monomers, e.g., crosslinkers or compounds that improve gas barrier properties, and the adjustment of key properties, s uch as degree of grafting, ion exchange capacity, and exte nt of crosslinking [3].

Polydopamine (PDA) a synthetic eumelanin polymer is highly interesting as thin film surface modification for a multitude of applications ranging from adhesive coatings for cell immobilization1 to biomimetic electron gates for artificial photosynthesis2. The polymerization of dopamine can be obtained via a chemical process at basic pH values higher than 7.43. Improved control of surface morphology can be achieved via electrochemical deposition e.g. by cyclic voltammetry, leading to thin films offering various functional groups such as amines, imines and phenolic groups at conductive surfaces.


The present notes prepare the countin of 'oscillatory modes of N fl = 3 light quarks', – u, d, s –, using the broken symmetry classification, extended to the harmonic oscillator symmetry of 3 paired oscillator modes. stands for the space rotation group generated by the sum of the 3 individual angular momenta of quarks in their c.m. system . The motivation arises from modeling the yields of hadrons in heavy ion collisions at RHIC and LHC, necessitating at the respective highest c.m. energies per nucleon pairs an increase of heavy hadron resonances relative to e.g. SPS energies, whence the included hadrons are treated as a noninteracting gas.


We discuss the mean and variance of the number 'point-particles' ♯DR inside a disk D R centered at the origin of the complex plane C and of radius R > 0 with respect to an infinite true polyanalytic process of index m∈Z+ by quantizing the phase space C via a set of generalized coherent states (CSs) z,m of the harmonic oscillator on L2R . By this procedure, the spectrum of the quantum observable representing the indicator function χDR ofD R (viewed as a classical observable) allows to compute the mean value of ♯DR . The variance of ♯DR is obtained as a special eigenvalue of a quantum observable involving the auto-convolution of χDR . By adopting a CSs quantization approach, we seek to identify classical observables on C, whose quantum counterparts may encode the first cumulants of ♯DR through spectral properties.


Objective To study the effect of 8 Hz infrasound on ryanodine receptor(RyR) expression in the hippocampus and temporal cortex of rats.Methods One hundred and forty male Sprague Dawley (SD) rats were randomly divided into the control group, and the 1, 7, 14, 21, 28, 35, 42 days groups with each treated by 8 Hz, 90 dB, 100 dB and 130 dB. The rats' brains were dissected as soon as the exposures were finished and the brains were taken to do immunohistochemical straining for RyR. The contents of RyR in the hippocampus and temporal cortex were detected under an optical microscope.Results The infrasound groups presented less expression of RyR in the hippocampus and temporal cortex, and the least were on the 21st day for 90 dB group and 100 dB group, but the 130 dB group presented two peaks, which were on the 14th day and on the 42nd day. The rats of 42 days presented the least expression of RyR in the hippocampus and temporal cortex( P 0.01) , and on the 21st day 100 dB group presented less expression than that of 90 dB group. After 21 days, the positive expression of 90 dB group and 100 dB group presented an increase.Conclusion The deceased RyR expression in the hippocampus and temporal cortex of rats could result from infrasound of 8 Hz.The rules of change are related to the parameters of infrasound.


Bioethics and organisational ethics are applied ethics disciplines with different objects of investigation. Bioethics focuses on moral aspects of caring for the health of individuals and populations, and organisational ethics on moral aspects of organisations' strategies and operations. So, these two disciplines converge in so far as they bring moral argument to bear on applied normative or value issues.

In addition, when organisational ethics addresses ethical issues in specifically healthcare organisations — such as government health departments, pharmaceutical companies, or private hospital groups — there is a more specific convergence of bioethics and organisational ethics in so far as both are concerned with the ethics of healthcare, and thus of health.


We made attempts to improve photocatalytic activity of TiO2 nanoparticles under visible light exposure by combining two additional treatments. N-doping of TiO2 by ammonia gas treatment at 600C increased absorbance of visible light. By coating thin film of polydimethylsiloxane (PDMS), and subsequent vacuumannealing at 800C, TiO2, became more hydrophilic, thereby enhancing photocatalytic activity of TiO2. Four types of TiO2 samples were prepared, bare-TiO2, hydrophilic-modified TiO2 (h-PDMS/TiO2), N-doped TiO2 (N/TiO2) and hydrophilic-modified and N-doped TiO2 (h-PDMS/N/TiO2). Adsorption capability was evaluated under dark condition and photocatalytic activity of TiO2 was evaluated by photodegradation of MB under blue LED (400 nm< λ) irradiation. N-doping on TiO2 was characterized using XPS and hydrophilic modification of TiO2 surface was analyzed by FT-IR spectrometer. It was found that N-doping and hydrophilic modification both had positive effect on enhancing adsorption capability and photocatalytic activity of TiO2 at the same time. Particularly, N-doping enhanced visible light absorption of TiO2, whereas hydrophilic surface modification increased MB adsorption capacity. By combining these two strategies, photocatalytic acitivity under visible light irradiation became the sum of individual effects of N-doping and hydrophilic modification.


Let E be an elliptic curve over a number field F and K = F ( √ D) be a quadratic extension of F. In this paper, for E and its quadratic D−twist ED, by calculating the cohomology groups, we obtain an explicit formula relating the orders of the Shafarevich-Tate groups ∐∐ (E/F ),∐∐ (ED/F ),∐∐ (E/K) and the ranks of the groups of F−rational points of E and ED. Then, assuming the finiteness of Shafarevich-Tate groups, we prove by a simple way different from the recent paper [Dok] that each square free positive integer n ≡ 5, 6 or 7(mod8) is a congruent number; and for several families of elliptic curves En : y 2 = x − nx, we prove that the orders of ∐∐(En/Q( √ n))(∼= ∐∐(E1/Q( √ n))) are equal to the squares of a product of 2−th powers with the n(or n/2)−th Fourier coefficients of some modular forms of weight 3/2. In particular, unconditionally, we obtain the values of ∐∐ (E/Q( √ D)) for some elliptic curves E and integers D, e.g., we show that all ∐∐ (E/Q( √ D)) are trivial for the elliptic curve E of conductor 37 and the 23 integers D in Kolyvagin's papers.


The fleck defect on surface of galvanized sheet was studied with electron backscattered diffraction(EBSD) and X-ray diffraction(XRD) technique.The results show that local coarse grains with {100}001 and {110}(001) orientations lead to formation of the fleck defect.It is supposed that the local coarse-grains are formed during hot-rolling due to the critical deformation in dual-phase zone.


Taijiquan,which expresses the wisdom and traditional Chinese cultural dialectic philosophy,is one excellent part of the Chinese Martial Art system.It explains the fighting skills,exercising,and the relationships between human beings and the human beings with nature perfectly.Taijiquan theory deserves the title of classic Martial Art theory.In the past,the theories of Taijiquan have been quoted frequently and mostly in a mystic way in the research of Martial Art.The result is that people may think Taijiquan is far away from their lives. However,the theory of Taijiquan is combined with the traditional Chinese cultural principle of living and surviving of people and is the bridge for people to make a better understanding of the traditional culture.


The author, a teacher educator, explains that because of a lack of training in language studies, many teachers do not view language as linguists do. She identifies three misconceptions (and the implications they have for English language learners) that still persist in education: Standard English is the best and most correct form of English, English dialects are improper and randomly created forms of the language, and dialects interfere with learning "proper" English and should not be used in the classroom. Such myths about language allow linguistic discrimination to continue in schools. The author debunks these myths and provides suggestions for teachers in terms of how to work with dominant and nondominant English varieties in their classrooms.


In order to examine current care planning experiences and practices for children whose primary carers are arrested and imprisoned in Victoria and New South Wales, this multi-method study gathered primary data from 151 imprisoned primary carers, 27 carers, three children and two adult children, along with 124 professional stakeholders. Secondary data was sought from both statutory and nongovernment organisations about imprisoned parents and children. Relevant rights, legislative and policy documents were also reviewed.


Rationale:The hyperpolarization-activated current Ih that is generated by hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) plays a key role in the control of pacemaker activity in sinoatrial node cells of the heart. By contrast, it is unclear whether Ih is also relevant for normal function of cardiac ventricles. Objective:To study the role of the HCN3-mediated component of ventricular Ih in normal ventricular function. Methods and Results:To test the hypothesis that HCN3 regulates the ventricular action potential waveform, we have generated and analyzed a HCN3-deficient mouse line. At basal heart rate, mice deficient for HCN3 displayed a profound increase in the T-wave amplitude in telemetric electrocardiographic measurements. Action potential recordings on isolated ventricular myocytes indicate that this effect was caused by an acceleration of the late repolarization phase in epicardial myocytes. Furthermore, the resting membrane potential was shifted to more hyperpolarized potentials ...


A bipartite state, which is secretly chosen from a finite set of known entangled pure states, cannot immediately be useful in standard quantum information processing tasks. To effectively make use of the entanglement contained in this unknown state, we introduce a way to locally manipulate the original quantum system: either identify the state successfully or distill some pure entanglement. Remarkably, if many copies are available, we show that any finite set of entangled pure states, whether orthogonal or not, can be locally distinguished in this way, which further implies that pure entanglement can be deterministically extracted from unknown entanglement. These results make it clear why a large class of entangled bipartite quantum operations including unitary operations and measurements that are globally distinguishable can also be locally distinguishable: They can generate pure entanglement consistently.


In order to overcome the restrictions of low-pass filters applied in radio-over-fiber(ROF) link,wireless communication system,etc,a new all-optical microwave photonic filter structure that can realize negative coefficients is presented and investigated.The system adopts a polarization sensitive electrical absorption modulator,of which the modulation factors for the transverse-magnetic(TM) polarized and the transverse-electric(TE) polarized lights are different.It's considered as linear modulation under small signal.The intersection angle between the fast axis and TE direction changes by rotating the plate of the polarization control unit(PCU),then the transformation of arbitrate polarization can be obtained.When the PCU is consisted of two reverse direction Faraday rotation tablets and a 1/2 plate,a negative coefficient filter is obtained,while combined with a 1/4 plate,a positive coefficient filter is obtained.


Mobile phones especially smart phones are getting more and more importance in day to day life. More of these mobile phones are now facilitated with number of applications that are using sensors. With the help of large no. of individual participants, aggregation which is computed from data is really useful and helps to predict the statistics of result. Aggregation guarantees more privacy of the data from individual participants. This paper provides a solution for preserving the individual participants privacy by using aggregate function like Sum, Min. Calculation of Sum aggregation is done without releasing the participant's information. Min aggregation is calculated using Sum aggregation. Min aggregation is nothing but minimum value of data. In this paper, a multi-hop network is considered where, there is a main aggregator at the highest level and mobile nodes are considered at lowest level and in between node sink is used at middle level. This system deals with dynamic leaves and joins in mobile sensing using the timestamp of the participants.


Dietary fibre has been a subject of study in companion animal nutrition for approximately 25 years, recently focusing on its benefits for dog and cat health and well-being. Pet animal diets contain significant amounts of carbohydrates, including dietary fibre. Depending on the properties of carbohydrates and their level in the diet, different physiological effects occur. High concentrations of dietary fibre affect appetite regulation and, potentially, gastric emptying, intestinal transit time and nutrient digestibility. Other effects include changes in faecal consistency and volume, increased production of short chain fatty acids, and alterations in the microbial population. Recent work on prebiotics and the benefits of a healthful large bowel microbiota has increased interest in dietary fibres and their potential value in clinical nutrition. This chapter is an update of the Fahey et al. (2004) comprehensive review of the effect of dietary fibre on companion animal nutrition and health. Studies conducted since 2004 will be emphasised.


One of the most useful logging tools for identifying losses and fractures is Formation Micro Imager. Drilling through the Dammam Formation is typically associated with substantial nonproductive time due to severe and often entire drilling fluid losses. The majority of remedy this problem require time for preparation, placement or setting. Combining between conventional well log and FMI log associated with drilling data, a special study of the shallow Dammam carbonate formation penetrate by wells is accomplished. For a better understanding of the loss mechanism, Image log study was highlighted to imagine the loss zones and as such adapt data to advance loss prevention or cure future scenario. Five images and conventional logs available data associated with drilling operation documents were applied to suggest best subsurface stratigraphic facies in order to knowledge sediment environment of Dammam Formation. Five image log facies were identified as representing the different environments within the different depths, large, fine vugs, carbonate layers, laminate interrupt and laminate. The stratigraphy succession reveals shallowing upward from deep water represented by laminate facies to more disturbed water signified by vuggy large facies. There are six internal picks zone according to GR log sign D90 at the top of Rus Formation, D80, D70, D65, D60, D50 and D40. It has been clear that nearly severe or complete losses events limit intensively in D60 and D65 based on logs interpretation analysis associated with drilling data.


Significance Statement In peritoneal dialysis, ultrafiltration is achieved at the cost of systemic glucose absorption with succeeding treatment-induced metabolic side effects and comorbidities. The transport pathway mechanisms that enable glucose transport and the extent to which they individually contribute to mass transfer are not fully understood. Intraperitoneal administration of phloretin, a nonselective blocker of facilitative glucose transporters (GLUTs), reduced glucose absorption and improved ultrafiltration during peritoneal dialysis in rats. Because GLUTs are also present in the human peritoneal membrane, phloretin or similar acting agents could reduce the metabolic cost of ultrafiltration and improve outcomes of peritoneal dialysis. Visual Abstract Background Harmful glucose exposure and absorption remain major limitations of peritoneal dialysis (PD). We previously showed that inhibition of sodium glucose cotransporter 2 did not affect glucose transport during PD in rats. However, more recently, we found that phlorizin, a dual blocker of sodium glucose cotransporters 1 and 2, reduces glucose diffusion in PD. Therefore, either inhibiting sodium glucose cotransporter 1 or blocking facilitative glucose channels by phlorizin metabolite phloretin would reduce glucose transport in PD. Methods We tested a selective blocker of sodium glucose cotransporter 1, mizagliflozin, as well as phloretin, a nonselective blocker of facilitative glucose channels, in an anesthetized Sprague–Dawley rat model of PD. Results Intraperitoneal phloretin treatment reduced glucose absorption by >30% and resulted in a >50% higher ultrafiltration rate compared with control animals. Sodium removal and sodium clearances were similarly improved, whereas the amount of ultrafiltration per millimole of sodium removed did not differ. Mizagliflozin did not influence glucose transport or osmotic water transport. Conclusions Taken together, our results and previous results indicate that blockers of facilitative glucose channels may be a promising target for reducing glucose absorption and improving ultrafiltration efficiency in PD.


Understanding the acoustic emission effects on bolts under cyclic loading is of great significance for the support of roadways. The presented research focuses on the acoustic emission characteristics of bolts under cyclic loading. The following main conclusions were drawn: (1) With a higher loading frequency, the acoustic emission counts rate increases, while the total energy released in a given cyclic loading path decreases. (2) A fitting formula is established according to the relationship between the tension amplitude and cumulative acoustic emission counts, which can analyze the tension magnitude level of the cyclic load. (3) A damage factor for a cyclic load is proposed based on the acoustic emission counts generated during the cyclic and monotonic loading process that can analyze the degree of damage to the anchorage system caused by the cyclic load. (4) Based on the spatial distribution of the acoustic emission orientation points and the acoustic emission energy generated during the pull-out process, the acoustic emission damage evolution process of the anchorage specimens is deduced, and the mechanism of the high stability of the pretension anchorage system after cyclic loading is analyzed. The above conclusions may provide some experimental references for the application of acoustic emission technology in bolts supporting roadways.


The spectacular collision of the Shoemaker–Levy 9 asteroid with Jupiter in July 1994 was a dramatic reminder of the inevitability of such catastrophes in the Earth's future unless steps are taken to develop methods for Earthapproaching object detection and possible interdiction. In this work, optimal (minimum-time) trajectories are determined for the interception of asteroids that pose a threat of collision with the Earth. An impulsive-thrust escape from the Earth is used initially to reduce  ight time but is followed with continuous low-thrust propulsion using values of thrust and speciŽ c impulse representative of electric motors. The continuous optimization problem is formulatedas a nonlinearprogrammingproblemusing the collocationmethod inwhich thedifferential equations of motion are included as nonlinear constraint equations. The use of low-thrust propulsion after Earth escape is shown to dramatically decrease the mass of the interceptor vehicle at launch.

Despite all modern techniques in registering terrestrial laser scanner point clouds, registration of multiple scan positions is still a crucial issue, especially in large projects. Processes like the detection of corresponding points in scans and placing targets in fields consume a lot of effort, time and money. Three points are the minimum number of common points required for registration. In this work, a new two points registration (TPR) algorithm is developed to register terrestrial laser scanner point clouds using only two common points automatically. Decreasing the number of the required common points to two points reduces one-third of the registration work in both field and laboratory. An accuracy assessment study is then performed to compare the registration accuracy of the developed algorithm and the traditional algorithm employing both the time of flight laser scanner and the phase shift one. The results show that the accuracy of the two algorithms is approximately equal within the considered point clouds accuracy in both cases.

Bacterial isolates were obtained from two sites in New Zealand contaminated with polycyclic aromatic hydrocarbons. Isolates capable of degrading polycyclic aromatic hydrocarbons were characterized in two mycobacterial groups according to phenotypic properties. These groups were supported by random amplified polymorphic DNA analysis. Nucleotide sequences of 16S ribosomal RNA genes from isolates representing each group were determined and compared with other mycobacterial 16S ribosomal RNA sequences. The taxonomic relationships of these isolates are considered.

I could not have imagined having a better advisor and mentor for my Doctoral program. Besides my advisor, I would like to thank DNP program director Dr. Pamela Aselton and the rest of the DNP faculties for their continued support and encouragement throughout this journey. Additionally, I would like to thank Bhutanese refugee community leaders and all participants. Finally, I would like to thank my DNP classmates, friends and family for assisting me to reach this milestone in my academic career. BHUTANESE REFUGEES QUALITY IMPROVEMENT PROJECT 5 Abstract Background: Bhutanese refugees in the United States frequently suffer from gastrointestinal diseases especially gastroesophageal reflux disease (GERD)and peptic ulcer disease (PUD) which may impact on their quality of life. Purpose: This DNP Project utilized individualized patient education to help improve knowledge on prevention and management of GERD to decrease exacerbations. Methods: Three sessions of individualized live patient education with 15 Bhutanese refugee patients living in Western Massachusetts were provided. Pre and post intervention surveys on patient's symptoms, quality of life, degree of patient knowledge about disease and self-care management and number of ambulatory care visits utilizing the GERD Impact Scale (GIS) questionnaire. Result: Statistically significant improvements were noted in overall symptoms and quality of life (5.25 points), knowledge scores (2.40 points) and number of ambulatory care visit (0.66 visit). The percentage of patients reported daily experiencing burning sensation on chest or behind the breast bone, pain on chest or behind the breast bone and sore throat or hoarseness was decreased by 53.3%, 26.67% and 33.3% respectively. Moreover, there was 62.5% decrease in ambulatory care visits. Conclusion: This culturally tailored individualized patient education program helped promote patient's knowledge on disease process, risk factors and self-care management of GERD and PUD. It was also helpful in reducing short term and long-term complications of GERD and PUD, increasing quality of life and decreasing ambulatory care visits among Bhutanese refugee population living in Western Massachusetts.


Development of bioengineered scaffolds of internal organs is one of the priority areas of tissue engineering. Decellularization allows to obtain biological (natural) scaffolds while preserving extracellular matrix and three-dimensional structure of organs. The primary goals of the present research were to investigate pathological characteristics of the decellularized rat heart scaffold and evaluate adhesion and viability of multipotent mesenchymal stromal cells (MMSC) during recellularization. Rat hearts were decellularized using a modified detergent-enzymatic method including sodium deoxycholate and DNAse. The results of morphological studies have confirmed the safety of extracellular matrix proteins and patency of the coronary vessels. Mechanical testing of decellularized and native samples of rat heart showed an increase of mechanical properties of the matrix during decellularization. During the conducted experiments on recellularization of obtained scaffold has been shown that the extracellular matrix was not toxic for MMSC which were viable and maintained their metabolic activity during prolonged cultivation on the scaffold.


With the rapid development of RFID technology, the demands of a relevant software system have been rising in recent years. The main challenges are showm to be in the design of middleware: (1) the amount of the raw RFID data is huge, so the middleware must own a strong ability to filter and compress data to reduce system overhead; (2) the raw RFID data is uncertain and incomplete, so there must be a mechanism to avoid defects in the middleware. Then we use a technology that can process the large-scale data and complex relationship between data in real time. The technology is Complex Event Processing (CEP). CEP is a technology that can process the relationship among events and large-scale complex RFID events. Based on the CEP, we, take the warehouse monitoring system as an example, and discuss events the rules of event filtering.


The aim of the study is to formulate goals and themes for the
methodology of social work with socially excluded Roma
families. In this paper I enlarge on a study whose basic
results I have presented in the first part of the book. In the
study, I focused on analysing interviews conducted with 17
experts (social workers, Roma pedagogical assistants, Roma
activists, teachers and clerics) with whom we talked about the
living conditions of socially excluded Roma families. The aim
of the research was to provide an answer to the question: "In
what ways are parental functions in socially excluded Roma
families ensured?" While in my previous article I addressed the
analysis of the interviews and described how our conversation
partners perceived the performance of parental functions, now I
would like to address the implications of the research results
for the practice of social work.


The ability to make effective co-parenting agreements and reduce conflict following divorce depends on a person's emotional state or readiness. This article outlines OPO's development and piloting of an Emotional Readiness Scale and subsequent digital tool, in collaboration with others. It comprises: a summary of a literature review to identify the key emotions experienced during separation and their influence on making effective childcare arrangements; item development derived from the review and expert consultation; feedback from separated parents regarding sources of support; practitioners' feedback regarding the tool's feasibility; and concordance between mediator comments and clients' scores on the tool. Ways of using this tool in practice and implications for further development are also discussed.


Advertisements (ads) are a common source of revenue for monetizing free mobile applications, but increase the energy consumption of a mobile device because the advertisement have to be fetched and displayed. In particular, the radio communication needed for the data transfer is power hungry and therefore advertisement sponsored free applications consume more energy than paid apps. This energy cost can be justified for Internet and social-applications but not for standalone games where always-on Internet connectivity is not necessarily required. In this paper, we analyze the energy consumed by mobile advertisements in an Android Phone. We measure the energy consumption by comparing the power usage of mobile phone games with and without advertisements. Our results show that advertisements in general consume significant amount of energy, but the consumption depends on how frequently advertisements are requested from the advertisement server(Ad Mob Server). In applications where advertisements are fetched frequently the energy consumed is higher, while in applications where advertisements are fetched rarely, it is lower. Moreover, we observe that the Ad Mob Server does not always send a new advertisement for each request but responds with a HTTP 304 (Resource Not Modified) leading to unnecessary usage of network and energy.

by Bethany Poulin, Undergraduate, Rhode Island College10/12/1932 9:00PM :I'm sure I'll lead my football team to the high school super bowl this year. After all, we just won our fourth game in a row. So far so good. Practice is crucial, so I took it upon myself to borrow a football from school to put in some extra time. Dad thought it was a great idea; Coach, on the other hand, is wondering where on earth that ball went!! My dad is going to be so proud when we win states! I can just hear him now, "Atta boy Biff, you showed everyone up out there!" I am worried about choosing schools though, as Dad says everyone is going to want to give me a football scholarship. I'll have a lot to consider; I wonder who will offer me the most opportunity? I would really like to attend the University of Virginia. Even if I wasn't so good at sports, I'm a good-looking kid and I can charm my way into people's hearts .. . well at least that's what Dad says all the time.11/23/1932 5:30PM :Football's going great as expected; got a touchdown for Dad in that last game and he was so proud. All the girls at school are practically drooling on their knees for me. However I'm a little worried about math, I'm failing and I need it to graduate! Bernard said he would tutor me, but he's such a nerd-I don't want to hurt my reputation by being seen with him. He basically worships me. It's sad really. Years from now he'll probably be in the stands at one of my pro games just begging for an autograph. Poor guy will never get laid.5/30/1933 10:30AMI'm trying to keep cool, but I just can't right now. I'm on the verge of a panic attack. I just discovered I failed math! How could they fail me, Biff Loman?! I charmed all the right people, said all the right things, I just don't understand . . . maybe Dad will be able to guide me in the right direction. If he would just see Birnbaum I'm sure he could convince him to pass me. Being a top salesman Dad's very persuasive. I suppose I could just make up the math test, but Dad's on a business trip to Boston, so I'll go find where he's staying and see what he thinks. Stupid Birnbaum and his ridiculous lisp, he'll regret this after my father is through with him.5/30/1933 7:15PM :Everything I thought I knew has just changed. I feel like my life has been flipped upside down. When I went to visit my father, he was with some whore! I wonder how long he's been cheating on my mother? He's a phony liar and I hate him. I'm not going to summer school to complete my math credit; in fact, I'm not attending college either. All these years that's what he has wanted me to do, but they're his dreams, not mine. He'll no longer live through my life; I don't want to be anything like him! But Mom, oh god how do I tell my mom? Do I tell her everything? I couldn't stand it if I was the one who broke her heart ... so maybe I should just leave. Start a new life. Yeah, that's what I'll do-head out West and work the ranches like strong men are supposed to. The more distance I put between Dad and me the better.4/15/1938 2:45PM :It's been a while since I wrote, and it's been a tough few years. But leaving home was the right thing I just know it. I have the strength and potential to someday outdo all these bums around me, and own my own land. The work is mostly hard labor, putting up fences, digging ditches, but I know I should be promoted or something soon. I absolutely hate when the boss tries to give me orders; I know what I'm doing. Clearly I'm the most valuable guy here anyway, and I don't like taking stupid orders from anyone. Without me this place would crash and bum. Lately I've had the urge to take something from work; last week I took a shovel and no one noticed. It makes me feel like I'm the one who holds the cards here, ya know? I'll try to take something more expensive this week; I'm way too slick to get caught!8/18/1942 2:29AM :Who am I fooling? I'm struggling to support myself. …


Abstract Intermolecular [2+2+2] cycloaddition of propargyl halides with 1,6-diynes was accomplished with a catalytic amount of Mo(CO)6 to generate benzyl halo barbiturates and Meldrum's acid derivatives containing a spiro linkage. Furthermore, we have extended this methodology to synthesize linearly fused Meldrum's acid derivatives via Diels–Alder reaction using rongalite chemistry.


Objective To study administration effect of Chinese TB control project in Changfeng county and provide basis for controlling TB prevalence. Methods 485 cases were studied. Results Initial smear positive rate of cases at the beginning of 2003 and recovery rate of retreated smear positive cases in 2003 were 80.8% and 62.0% respectively, which were much higher than that in 2002. Conclusions Discovery of TB cases, especially for initial smear positive case, should be enhanced and DOTs and related management should be followed in order to control TB.


What is Benchmarking? Benchmarking is a process of comparison between the performance characteristics of separate, often competing organisations intended to enable each participant to improve its own performance in the marketplace. Its objectives are to obtain a clearer understanding of competitors and of customers' requirements. Benchmarking will also enable innovations (either of process or product) to spread more rapidly through an industry and across industries where appropriate (Beckford, 1998). The benchmarking theory is built upon performance comparison, gap identification and changes in the, it seems obvious that benchmarking: Despite these benefits, time constraints, competitive barriers, cost, lack of both management commitment and professional human resources, resistance to change, poor planning and short term expectations are regarded as the main problems affecting successful benchmarking research (Bendell et al., 1993). A poorly executed benchmarking exercise will result in a waste of financial and human resources, as well as time. Ineffectively Helps organisations to understand where they have strengths and weaknesses depending upon changes in supply, demand and market conditions Allows organisations to realise what level(s) of performance is really possible by looking at others, and how much improvement can be achieved Helps organizations to improve their competitive advantage by stimulating continuous improvement in order to maintain world class performance and increase competitive standards Helps to better satisfy the customers' needs for quality, cost, product and service by establishing new standards and goals Promotes changes and delivers improvements in quality, productivity and efficiency; which in turn bring innovation and competitive advantage Is a cost effective and time efficient way of establishing a pool of innovative ideas from which the most applicable practical examples can be utilised To be keen on new developments within the related area, and improves the motivation of employees. executed benchmarking projects may have tarnished an organisation's image (Elmuti and Kathawala, 1997). Moreover, there is no single 'best practice' because it varies from one person to another and every organisation differs in terms of mission, culture, environment and technological tools available. Thus, there are risks involved in benchmarking others and in adopting new standards into one's own organisation. The 'best practice' should be perceived or accepted to be among those practices producing superior outcomes and being judged as good examples within the area. Finally, benchmarking findings may remove the heterogeneity of an industry since standards will themselves become globally standardised and attempts to produce differentiation may fail (Cox and Thompson, …


T HE INFANTRYMEN who had served with Alexander in the conquest of Asia were justly famous.! Hieronymus of Cardia, whose views we may deduce from Diodorus and Plutarch,2 gave a special accolade to the elite corps of that infantry, the Silvershields. "At this time lin 317 B.C.]," wrote Diodorus, "the youngest of the Silvershields was about sixty, most of the others about seventy and some even older, but all were irresistible through their experience and strength. So great in their case was their deftness of hand and their courage; for they had been trained continually in the school of danger." "The Silvershields were indeed the oldest of the men who had served with Philip and Alexander," wrote Plutarch of the same occasion, "masters of war without a defeat or a reverse during that span of time, many being already seventy and none younger than sixty. "


AIM: The study presents the results of the adaptation of an academic self-efficacy scale. Specifically, the purpose of the study was to analyse the internal structure of the translation and adaptation of the ASES scale by Chemers, Hu y Garcia (2001). METHOD: 4950 Chilean university students participated. Additionally, to study the Equivalence/Invariance of Measurement between different groups of students, we have performed a factorial invariance analysis. RESULTS: The results indicate that the scale has adequate psychometric properties; they also show the existence of a two-factor structure consistent from the substantive point of view and with an adequate statistical adjustment. Factorial invariance analysis shows the existence of metric invariance between the compared groups, CONCLUSIONS: The evidence shows the validity of the scores and their equivalence among groups of students.


The effects of the timing of initial feeding (0, 1, 2 3 and 4 days after yolk exhaustion) and temperature (15, 18 and 21degrees C) on the point-of-no-return (PNR), survival and growth of laboratory-reared Japanese flounder Paralichthys olivaceus larvae were studied under controlled conditions. The larvae reached PNR on 7(.)7, 5(.)2 and 4(.)2 days-post-hatching (dph) at 15, 18 and 2 V C, respectively. At each temperature, larval growth did not differ significantly among the delayed initial feedings 1 day before PNR but decreased significantly in larvae first fed after that. In the treatments where initial feeding was equally delayed, larvae grew significantly faster at 18 and 21degrees C than at 15degrees C. The larvae survived apparently better at 15 and 18degrees C than at 21degrees C when initial feeding was equally delayed. At each temperature, survival of the larvae first fed before PNR did not differ noticeably, while delayed initial feeding after that apparently reduced their survival. These results indicated that there existed a negatively temperature-dependent PNR in the Japanese flounder larvae. Survival and growth of the larvae strongly depended on temperature as well as the timing of initial feeding. High temperature accelerated the yolk exhaustion and growth of the larvae and thus reduced their starvation tolerance and survival. To avoid potential starvation mortality and obtain good growth, the Japanese flounder larvae must establish successful initial feeding within 2 days after yolk exhaustion at 15degrees C and within 1 day at both 18 and 21degrees C.

In recent years, the explosive increase of information facilitates the massive knowledge graphs, which in turn increase burden of people to understand and leverage the regularity behind these superficial facts. Therefore, the metaknowledge, defined as the knowledge about knowledge, is proposed to identify complex processes of knowledge production and consumption. Unfortunately, even though the current correlation-based rule mining methods in knowledge graph distill the rule-formed metaknowledge, they can not explain the processes of knowledge production. In this paper, we focus on capturing the metaknowledge with causality which is generally regarded as one of the most promising techniques to reveal the interactions between components in the complex system. To the best of our knowledge, this is the first attempt to interpret the knowledge graph from the causal perspective. For this purpose, we propose a causal metaknowledge method for link prediction, which achieves entity-level link prediction by discovering concept-level topological causality. Specifically, we first formalize causal metaknowledge as causal rule, following the form of logical rule. Then, we transform the relational data into propositional data to learn the causal relationships between topological structures. And an efficient algorithm for discovering local causal relationships is proposed using the d -seperation criterion. Eventually, the causal rules generated based on the mined relationships are used for link prediction. Both simulation-based and real data-based experiments demonstrate the effectiveness of the proposed approach, especially under the Out-of-Distribution(OoD) settings.


A traditional solar air-source heat pump heating system cannot effectively utilize solar energy, and it consumes large amounts of energy when operating during cold nights. Accordingly, a conventional heating system has been improved by phase-change heating to form a new phase-change thermal storage solar air-source heat pump heating system. Based on the TRNSYS simulation platform, a heating simulation study of the improved phase-change heating system was carried out in Xi'an City. The results show that the addition of phase-change thermal storage technology allows the heating system to make better use of solar energy, and the efficiency of the solar collector is increased by 5.9%; the presence of the phase-change material effectively reduces the rate of temperature drop inside the water tank, making the water supply temperature more stable; during the whole heating period, the improved phase-change heating system saved 484.91 kWh of operating energy, showing a very good energy-saving effect.


Avian influenza is dangerous disease for poultry, because it can cause high
mortality on poultry. The disease can spread fast and broad. Many avian influenza cases
occur in Indonesia. Appropriate measure is necessary to identify whether individual or
population was attacked by avian influenza. There are some ways commonly used to
detect chicken attacked with avian influenza. One of the methods is serological
detection by Haemagglutination Inhibition test on serum. Haemagglutination inhibition
test is not only used to identify chicken attacked with avian influenza by the test also
indicate antibody titer level of an individual so the individual can be defined protected
from avian influenza or not.
This final assignment was intended to identify result of serological examination
of avian influenza in serology laboratory, Balai Besar Veteriner Wates, Yogyakarta.
Data was taken by observation interview and study data in the laboratory.
Result of serological examination in the laboratory in2011 indicate 8381
specimens of avian influenza serology in which 361 sample have negative antibody titer
interpretation, 99 samples have low antibody titer interpretation, and 3021 sample has
high antibody titer interpretation. In 2012, 7164 avian influenza serology specimens
were examined consisting of 2820 samples with negative antibody titer interpretation,
1335 samples with low antibody titer interpretation and 3009 samples with high
antibody titer interpretation.


Tuberculosis (TB) remains one of the most common deadly infectious diseases on the planet and the diagnosis, treatment and prevention of this disease present serious global public health challenges. 1 The TB treatment regimen takes too long to cure and is complicated to administer, and anti-TB drugs can be toxic. 2 There is no efficacious vaccine for TB. 3 Rates of new infections are still rising in many endemic areas where TB co-infects those with HIV/AIDS. 4 Treating this co-infection is further complicated by the surge of multi-drug resistant strains of Mycobacterium tuberculosis (Mtb) . 5 TB diagnosis remains antiquated and inadequate in most parts of the world. 6,7 Given that one-third of the world's population is assumed to have been exposed to Mtb and to have developed latent infection, diagnostic assays based on the host immune response (whether cellular or humoral) often fail to distinguish active TB from latent cases. 8,9 Unfortunately, identifying individuals with active pulmonary disease (the source of disease transmission) and distinguishing them from those with latent (non-transmissible) infection is critical to provide prompt and appropriate therapy to minimize the spread of TB.  Active pulmonary TB is typically diagnosed by finding Mtb in sputum by acid-fast smear, a labor-intensive process requiring trained personnel and with widely varied sensitivity in different settings (20-60%).


This paper concerned with the hybrid network system with state multiplicative noises, packet dropouts and linear correlation additive white noises. Firstly, the dimension of the original system is augmented by the method of augmented matrix. By introducing the fictitious noises to compensate the uncertainty of multiplicative noises and transform the augmented system into a standard system with only determined noise variance. Then, based on the standard system, local steady-state Kalman estimators are designed by using Lyapunov equation approach, and the SICI steady-state Kalman fusers (predictor and filter) are presented by using the sequential inverse covariance intersection algorithm. In this paper, two SICI steady-state Kalman fusers are presented combined with a hybrid networked system, which expand the application fields of the new ICI information fusion algorithm, which overcomes the shortcomings that the large amount of calculation given by the original CI fusion algorithm, and overcomes the large conservation of the original SCI fusion algorithm. It is proved that the accuracy of SICI fuser is higher than that of SCI fuser. Finally, some simulation results are given to verify the effectiveness of the proposed algorithm.


In active magnetic regenerative refrigerators (AMRRs),the magnetic power consumption based on thermodynamic calculation can be erroneous due to the varying temperature gradient inside active magnetic regenerator (AMR) bed,unsymmetrical magnetic field distribution,length difference between AMR and magnet gas gap,and the phase between different AMRs.Based upon classical molecular field theory,the magnetic power is obtained by calculating the magnetic forces imposed on AMRs.Consequently,the length ratio (δ) of AMR to gas gap and the phase difference is optimized. The numerical results reveal that the peak magnetic force and magnetic power increase with increased temperature gradient,maximum values are found for both peak magnetic force and magnetic power whenδis between 0 and 1,the magnetic power reaches its minimum when the phase of right AMR isπahead of left AMR at zero temperature gradient,and the phase difference at minimum magnetic power increases with increased temperature gradient.


Background

A wide range of diagnostic prevention programs are offered free of charge by the German health care system. However, utilisation rates remain low. Non-participation forgoes the potential long-term health benefit in particular with modifyable risk factors. As employees show up for work on a regular basis, the workplace setting itself might offer a platform to identify and address under-utilization.

Therefore, the goal of our study was to examine occupational determinants that help to identify …


s for Oral Presentations Oocyte Survival and Follicle Maturation Requires Irx3 and Irx5 to Promote Communication Between Somatic and Germ Cells in the Mouse Ovary Anqi Fu, Kathleen Krentz, Jessica Muszynski, Claire Holdreith, Mamawa Konuwa, Cristel Kpegba, Chi-chung Hui, Joan Jorgensen Background: Follicle development and maturation within the ovary depends on intimate communications between the germ cell and its surrounding somatic cells. Our previous results using the Fused Toes (Ft) mutant mouse model showed disrupted oocyte – granulosa cell contacts leading to oocyte and follicle death. Among the genes deleted in the Ft locus, only Irx3 and Irx5 (Irx3/5) exhibited ovary specific expression upon comparison of male versus female transcripts during gonad development. Hypothesis: We hypothesize that Irx3/5 are critical for coordinating germ cell – somatic cell communications underlying oocyte and follicle survival. Methods: Real-time qPCR and immunofluorescence (IF) were used to characterize Irx3/5 transcript levels and protein expression. Double knockout (DKO) of Irx3/5 is embryonic lethal; therefore, kidney capsule transplantation (KCT) of ovaries were used to analyze postnatal development. To evaluate the role of Irx3/5 in somatic cells in the developing ovary, we generated somatic cell specific double knockout mouse models using Sf1Cre: Sf1Cre;Irx3fIrx5G/Irx3ΔIrx5G (Irx3/5 sFΔ), and Sf1Cre;Irx3fIrx5G/Irx3fIrx5G (Irx3/5 sFF). Results: Irx3/5 showed similar expression patterns during ovary development as their transcripts increased during germline nest formation and peaked around birth when nests broke down to form primordial follicles. Shortly thereafter, their expression diminished. IRX3 and IRX5 were co-localized to somatic cells during development and then were detected in both germ and somatic cells around birth. Histology and transmission electron micrograph of KCT ovary grafts showed that Irx3/5 DKO follicles developed abnormal granulosa cell morphology, gaps between germ and somatic cells, and oocyte death similar to that seen in the Ft mutant model. Histological analysis of adult Irx3/5 sFΔ mutant ovaries displayed an overall smaller ovary size with more zona pellucida remnants and few corpora lutea. Because the Irx3/5 sFΔ mice were small and too weak to perform breeding studies, we examined fertility using superovulation followed by in vitro fertilization. Our current results indicated that Irx3/5 sFΔ mutant females ovulated fewer oocytes, had a higher incidence of egg fragmentation, and fewer 2-cell embryos compared to controls. Irx3/5 sFF mutant mice were robust and preliminary breeding study results indicated that mutant females could reproduce, but were subfertile. Conclusions: Together, our results indicate that Irx3/5 work together during follicle development in the ovary to promote communication between the oocyte and nascent granulosa cells ensuring oocyte survival and proper follicle maturation. These functions may depend on Irx3/5 expression specific to ovarian somatic cells. Antibody Conjugated -Cardiac Glycosides as Potent and Highly Selective Agents for Treatment


Information and communication technology for development (ICTD) involves using information and communication technologies (ICTs) to improve the well-being of people in resource-constrained environments. Because ICTD projects involve crafting technical information and the ICTs that convey it, ICTD involves challenges familiar to technical communicators, such as balancing stakeholder interests and building credibility necessary to influence stakeholders. This article presents how trust and credibility affect ICTD projects, describing implications for development contexts and for distributed work environments.


Near ground maneuvers, such as hover, approach and landing, are key elements of autonomy in unmanned aerial vehicles. Such maneuvers have been tackled conventionally by measuring or estimating the velocity and the height above the ground often using ultrasonic or laser range finders. Near ground maneuvers are naturally mastered by flying birds and insects as objects below may be of interest for food or shelter. These animals perform such maneuvers efficiently using only the available vision and vestibular sensory information. In this paper, the time-to-contact (Tau) theory, which conceptualizes the visual strategy with which many species are believed to approach objects, is presented as a solution for Unmanned Aerial Vehicles (UAV) relative ground distance control. The paper shows how such an approach can be visually guided without knowledge of height and velocity relative to the ground. A control scheme that implements the Tau strategy is developed employing only visual information from a monocular camera and an inertial measurement unit. To achieve reliable visual information at a high rate, a novel filtering system is proposed to complement the control system. The proposed system is implemented on-board an experimental quadrotor UAV and shown not only to successfully land and approach ground, but also to enable the user to choose the dynamic characteristics of the approach. The methods presented in this paper are applicable to both aerial and space autonomous vehicles. flown at least 10 seconds for the visual motion parameters filter then the required autonomous visual control mode is engaged by a switch on the remote controller. A total of six experiments are shown here; the first experiment demonstrates the autonomous visual landing achieved by the Tau strategy using a maneuver constant of k = 0 . 2 starting from height z 0 = 4 m and downward vertical velocity v z 0 = 0 . 77 m/s. The second experiment is performed from similar initial conditions ( z 0 = 4 . 6 m and v z 0 = 0 . 88 m/s) but using a different maneuver constant k = 0 . 45 . The height and vertical velocity for experiments 1 and 2 Figure respectively.


It is shown that relay protection and measurement devices for electrical installations with voltages of 6–20 kV can be constructed on the basis of reed relays. To calculate the currents in the busbars at which the reed relays are located, equations are suggested based on the Biot–Savart–Laplace law and the experimentally derived improving coefficients. The method for determining and accounting for interferences acting on reed relays is presented. The sensitivity of reed relays and errors in determining currents according to the equation suggested are estimated.
