One in ten of the UK population use complementary medicine each year and 50% are lifetime users. The recent House of Lords' Report has clearly defined a public need for further research into both safety and efficacy. The Department of Health research capacity building initiative is one of the first main responses to the Select Committee's recommendations. We know that within this emerging field we have developed a unit with cooperative ventures within the university, both intra-faculty and inter-faculty. As a consequence, we have been able to draw in major funding along with a growing body of academic publications. Our unit was established by George Lewith in 1995 with his appointment as Honorary Visiting Senior Lecturer. He now has a University contract as a Reader within the Department of Primary Care where the unit is located. The unit was initially provided with core funding by the Maurice Laing Foundation and has been able to generate substantial amounts of soft money funding for a number of minor and major projects from charitable (including Wellcome) sources as well as National Health Service Research and Development (NHS R&D) funding. Laing funding continues to provide our unit with an administrative core. Dr Lewith has been appointed as a Visiting Professor to the School of Integrated Health at the University of Westminster. The Department of Health is now providing funds for research capacity building within complementary medicine and we have been successful in obtaining Department of Health support for two post-doctoral fellows (Peter White and Sarah Brien) and two PhD students during the first 2 years of the awards. The Department of Health is also funding complementary and alternative medicine (CAM) projects within palliative cancer care (£300 000) and we have successfully applied for this funding, in conjunction with Jessica Corner as the primary investigator. Wellcome is currently funding 37% of the applications it puts out for review in the field of CAM and is considering further initiatives in the light of the Department of Health proposals. The Medical Research Council has publicly stated that it welcomes quality applications in this area: our initial asthma and homeopathy study was alpha rated, the Alexander Technique study was alpha– alpha rated and funded. There is clearly now an opportunity for substantial growth in this area of research and the track record that we have developed in Southampton makes us well placed to capitalize on these initiatives. Over the last 8 years we have created a unique multidisciplinary team (non-clinical post-docs, doctors, nurses, physiotherapists, pharmacists and health psychologists) in Southampton, which has developed considerable skill in primary clinical research within CAM. These studies have been directed at asking not only where complementary therapies may be most applicable but also whether and how they work. Furthermore, our research has led us to understand that the nature and content of the therapeutic relationship within complementary medicine is of paramount importance, and therefore we are in the process of developing clinical trial methodology that will allow us to look at the consultation independently from a particular therapeutic intervention, focusing particularly on the non-specific effects of homeopathy and acupuncture in chronic disease. The major studies in which our unit has been involved to date are as follows:


Zinc oxide (ZnO) thin films were deposited on glass substrate by Radio frequency (RF) magnetron sputtering. The effect of substrate temperature on the microstructure of the ZnO films has been investigated. Crystal structure and surface morphology of the films were examined by X-ray diffraction (XRD) and atomic force microscopy (AFM). XRD patterns and AFM images show that the crystallinity and grain size are increasing with the increase of substrate temperature.


Owing to the advantages of the light self weight,great carrying capacity and good seismic performance of steel and concrete composite beams,the beams have been widely applied in the field of bridge construction and old bridge rehabilitation and strengthening in China and have therefore achieved good social and economic benefits.In this paper,with reference to the practical engineering example,the application of the steel and concrete composite beams to the rehabilitation and strengthening of an old double-curved arch bridge is presented.The utilization of the characteristics of the composite beams and the transformation of structural system greatly improve the carrying capacity of the rehabilitated or strengthened structure and consequently,reach the goal of upgrading the load and operation capacity of the bridge and provide a new way for rehabilitation and strengthening of old double-curved arch bridges.


Without AGN feedback, simulated massive, star-forming galaxies become too compact relative to observed galaxies at z ≲ 2. In this paper, we perform high-resolution re-simulations of a massive ($M_{\star }\sim 10^{11}\, \rm {{\rm M}_{\odot }}$) galaxy at z ∼ 2.3, drawn from the Feedback in Realistic Environments (FIRE) project. In the simulation without AGN feedback, the galaxy experiences a rapid starburst and shrinking of its half-mass radius. We experiment with driving mechanical AGN winds, using a state-of-the-art hyper-Lagrangian refinement technique to increase particle resolution. These winds reduce the gas surface density in the inner regions of the galaxy, suppressing the compact starburst and maintaining an approximately constant half-mass radius. Using radiative transfer, we study the impact of AGN feedback on the magnitude and extent of the multi-wavelength continuum emission. When AGN winds are included, the suppression of the compact, dusty starburst results in lowered flux at FIR wavelengths (due to decreased star formation) but increased flux at optical-to-near-IR wavelengths (due to decreased dust attenuation, in spite of the lowered star formation rate), relative to the case without AGN winds. The FIR half-light radius decreases from $\sim 1\, \rm {kpc}$ to $\sim 0.1\, \rm {kpc}$ in $\lesssim 40\, \rm {Myr}$ when AGN winds are not included, but increases to $\sim 2\, \rm {kpc}$ when they are. Interestingly, the half-light radius at optical-NIR wavelengths remains approximately constant over $35\, \rm {Myr}$, for simulations with and without AGN winds. In the case without winds, this occurs despite the rapid compaction, and is due to heavy dust obscuration in the inner regions of the galaxy. This work highlights the importance of forward-modelling when comparing simulated and observed galaxy populations.


2I/Borisov is the second ever interstellar object (ISO). It is very different from the first ISO 'Oumuamua by showing cometary activities, and hence provides a unique opportunity to study comets that are formed around other stars. Here we present early imaging and spectroscopic follow-ups to study its properties, which reveal an (up to) 5.9 km comet with an extended coma and a short tail. Our spectroscopic data do not reveal any emission lines between 4000–9000 Angstrom; nevertheless, we are able to put an upper limit on the flux of the C2 emission line, suggesting modest cometary activities at early epochs. These properties are similar to comets in the solar system, and suggest that 2I/Borisov—while from another star—is not too different from its solar siblings.


Forestry Code of the Russian Federation provides forests use giving forestry areas with and without forestry resources eliminations. Economic relations in the sphere of forests use are connected with their charged use. In this case forestry resources and rights of forestry areas use becomes a commodity, the objects of market relations, come into the market of goods in a material form or in a form of services of intravital forest use. The income received after goods realization presents the cost, by means of getting income the principle of charged forests use is realized. Market interest of the owner id getting maximum possible income from his property. The article considers the questions, connected with forestry resources economic estimation. This question has being discussed in Russia for many decades. Nevertheless, the existing approaches and methods of estimation still have strictly industrial notion: mainly only woody is considered as a dominating part of forestry wealth. Non-woody forestry resources are not included into a resource potential and are not considered as an economic object, which is able to provide additional forestry income. Keywords—economic estimation of forestry resources; woody products; non-woody products; forests renting; effectiveness of foressts use.


left in the mother liquor. All the composites were characterized by scanning electron micrograph, X-raydiffraction, and thermogravimetric/diffenential thermal analysis techniques. The electrochemical performances of the compositeswere also investigated and one composition delivered a discharge capacity as high as 231 mAh g


A new method is proposed for the design of two-channel linear-phase perfect reconstruction QMF banks. The analysis lowpass filter is first designed by a conventional method, and then the synthesis lowpass filter is obtained by using a null-space projection approach. This method is then extended to the design of two-channel perfect reconstruction QMF banks with low reconstruction delay, which are desirable in some applications. Two design examples are given to illustrate the proposed methods.

The trans-Himalayan region of NW India along with western part of Tibet, Karakoram,and Hindukush range is hosting thousands of glaciers ensuring perennial freshwater supply to the Indian subcontinent and supporting a large fraction of the global population. The peculiar physiography not only limits the entry of water enriched Indian Summer Monsoon winds to this region but also give passage to dry winds of barren desert of Taklamakan, the Aksai Chin,and western Tibet, making it a cold desert. The Quaternary glacial and interglacial phases govern the present geomorphological setup of the region, wherein the glacial process designed the basic framework, which subsequently modified by the fluvial-lacustrine-aeolian processes.Over the years, our understanding in drawing climatic inferences from the sedimentary archives has improved significantly. However, the discrepancy in chronological results among and within different dating techniques is posing a serious challenge. Since the region is experiencing cold desertic climate and being in the rain shadow zone of the Indian Summer Monsoon (ISM), earlier studies show that the major source of moisture received by the Mediterranean Sea.However, the recent isotopic study of the Indus river water along with other major tributaries and minor streams, it is concluded that ISM source is equally important supplier of the moisture in the Ladakh region of NW India.


The MsXα method has been used to investigate the electronic structure of the atom pairs He-He, He-Ar, and Ar-Ar. Results are presented for ground state and excited state configurations over a wide range of R values. The computed interactions exhibit Born-Mayer repulsion, and the calculations demonstrate how the Xα orbital energies can be used to predict crossings between interaction potentials. An analysis is presented of the usefulness of the Xα theory for the understanding of collision phenomena.


Purpose— Mice with conditional deletion of fibroblast growth factor receptor 2 (Fgfr2) in metanephric mesenchyme (Fgfr2 Mes−/− ) have ureteric bud induction abnormalities. Our goal was to determine if Fgfr2 Mes−/− mutants developed abnormally positioned ureters predisposing to vesico-ureteral reflux (VUR). Materials and Methods— We measured common nephric duct (CND) lengths and assayed for apoptosis in embryonic day (E) 11.5 mice. We performed 3 dimensional (3D) reconstructions of and real time PCR and whole mount in situ hybridization for Fgfr2 in urinary tracts in E15.5 embryos. We performed cystograms followed by 3D reconstructions in postnatal animals. Results— Compared with controls, Fgfr2 Mes−/− embryos had increased CND lengths (with no differences in apoptosis)


Problem-Based Learning has been studied over three decades in various subjects and schools, This meta-analysis study aimed to synthesize the most recent findings of the effect of Problem-Based Learning (PBL), specifically on students' mathematical reasoning ability. The data were obtained from relevant primary studies published in national and international journals or proceedings during 2014-2021. Ten effect sizes from eight studies that fulfilled the inclusion criteria were analyzed using a systematic review and meta-analysis. JASP 0.15.0.0 software was used to measure the formula of Hedges g to determine the effect size. The result showed that PBL has a strong effect on students' mathematical reasoning ability (gRE = 2.062, 95% CI [1.436, 2.689], p 0.001) when compared to traditional learning. The results of the analysis of moderator variables revealed that publication year (Qb = 5.460, p 0.05) and sampling technique (Qb = 9.032, p 0.05) had significant effect on the effectiveness of PBL on students' mathematical reasoning ability, while educational levels (Qb = 1.649, p 0.05), sample size (Qb = 2.081, p 0.05) and publication sources (Qb = 0.573, p 0.05) did not show any significant effect. The result of this study provides important information for further meta-analysis study and the implementation of PBL in mathematics learning.

After identifying face to face the existence of company interests and society's interests, this article establishes the need for taking both into account in the application of business regulation with a view to orientating them towards real development, linked to better distribution patterns and social improvement, a concept more compatible with the modern idea of development.


This paper begins by noting the centrality of the issue of working-class school failure within the sociology of education in Britain. It argues that recent government policies have taken insufficient account of sociological work on the impact of social class on educational success and failure. It also suggests that sociologists should pay more attention to middle-class education. The importance of this is illustrated through reference to research on the trajectories of pupils receiving different forms of secondary education. The paper then argues that social inclusion policies need to address a variety of forms of middle-class self-exclusion from mainstream public provision as well as working-class social exclusion. It concludes that education policy needs to be located within a broader social policy framework.


This paper reviews some expected systems performance aspects of NASA's ProSEDS (Propulsive Small Expendable Deployer System) electrodynamic (ED) tether mission after recently being required to lower its initial orbit from 360 km to 285 km. In addition, the ProSEDS tether, which has conductive and non-conductive sections, shortened its nonconductive section thereby reducing overall tether length from 15-km to 12-km long. The International Reference Ionosphere (IRI) model is not as accurate as previously predicted when the altitude is less than 300 km and it was found that a factor of 0.65 should be multiplied to the electron plasma density on the IRI 1990 model to compensate for this effect. The ED characteristics of ProSEDS are being theoretically predicted using software called TEMPEST developed at the University of Michigan. Using OML (Orbital Motion Limited) theory for tether collection TEMPEST demonstrated that ProSEDS will de-orbit in 90 hours instead of the originally predicted 160 hours. The induced EMF (electromotive force) range will remain approximately the same from 400 V to 1000 V as will the collected current range, which varies according to altitude. Also, it takes 50 hours for the atmospheric drag to become stronger than the electromagnetic drag from the tether at 285 km as opposed to the 130 hours at 360 km. Various errors in the potential measurement of ProSEDS stem from: (1) the electron sheath at the upper end of the tether, (2) a "phantom current" occurring throughout the tether, and (3) the measurement of the potential used for current collection on the nozzle of the Delta II module. The "phantom current" also causes an extra 2 km per day de-orbit. In addition, there is a 0.733-mA theoretical current that travels into the Delta II from the tether that must be emitted. This potential is plotted versus the atmospheric density to show how much current is collected. The total potential error in the ProSEDS system ranges from 4–71% without hollow cathode operating, depending on the density of the electron plasma.


Latin American cooperativism is heterogeneous, like its roots and paths of development. During the XX century this situation has arisen starting from two basic co-operative types: financial co-operatives and agricultural ones. The article describes these processes, their endogenous and exogenous forces and the three levels of current development which are derived from them. These levels are illustrated through three typical countries: Argentina, Venezuela and Chile.


Aim. The screening of molecular genetic markers for a minimally invasive assessment of the radiation therapy effectiveness for rectum malignant tumors.Materials and methods. The study was carried out in 4 stages: 1) bioinformatic analysis of TCGA (The Cancer Ge- nome Atlas) databases using the GISTIC algorithm; 2) validation of bioinformatics analysis data in a model experiment on cell culture; 3) study of genes copy number features validated in a model experiment in patients with different responses to radiation therapy; 4) determination of the gene copy number in cell-free DNA in patientswith different responses to radiation therapy. 100 patients with rectum adenocarcinoma (G1–2), as well as 30 apparently healthy individuals, took part in the work. Radiotherapy was carried out according to the standard protocol (single focal dose 2.4 Gy, total focal dose 54 Gy) on a Novalis TX linear accelerator. The relative copy number of genetic loci was determined by real-time quantitative polymerase chain reaction.Results. Bioinformatic analysis revealed 32 candidate genetic loci. Validation of these markers on irradiated HT-29 cells showed that the copy number of BRCA2, H2AX, CASP9 and RBBP8 genes was increased, while the copy number of BCL2 gene was reduced relative to intact cells. In 74 patients with a partial response to radiation therapy, an increase in the copy number of BRCA2, H2AX, RBBP8 and BCL2 was found, which positively correlated with the copy number of these genes in blood plasma cell-free DNA.Conclusion. The application of an integrated approach based on TCGA database bioinformatic analysis, radiation therapy modeling in cell culture and validation of the identified markers on tissue and blood samples of patients with rectal adenocarcinoma revealed RBBP8, BRCA2, H2AX and BCL2 genes copy number association with the preoperative radiation therapy effectiveness.


Summary Nine lactating dairy cows were injected with thyroxine daily at a level 50% above their individual winter thyroxine secretion rates during the spring and summer to determine the effect upon milk yield, body temperature, and body weight. The body pool of thyroxine was raised to its ultimate level by one injection of thyroxine at the initiation of the experiment. One cow reached a new peak of milk yield (weekly average) during the 2nd wk, one the 3rd wk, and the seven other cows the 4th wk. The mean increase in milk yield was 27.6%, with a range from 12.1 to 67.9%. The effect of thyroxine at this level during the summer appeared to pose no problem in heat dissipation. The elevation in rectal temperature of the experimental cows was very small, with fluctuations in treated and nontreated cows quite comparable. The mean body weight loss was 9.7%, with a range of 3.7 to 14.2%. This loss was regained within 2 wk after cessation of thyroxine treatment. On the basis of the observed range in thyroxine secretion rate, and the beneficial effect of thyroxine upon milk yield administered at 50% above their secretion rate, it was suggested that the level of feeding thyroprotein might be reduced from 15g to about 10 g/1,000lb body weight/day in the great majority of dairy cows.


Smart construction materials are intelligent composites that have properties different from normal materials. The smartness of building materials and structures is achieved through material composition design, special processing, the introduction of other functional components, or modification of the microstructure. Conductive concrete is one of the smart construction materials. It is a mixture containing a certain amount of electrically conductive components (filler). It is designed to enable the conduction of electricity. When the conductive filler used is a natural material, the result is green conductive concrete. The current work deals with a review that summarizes the vital points of the incorporation of conductive fillers in construction materials. The types of conductive filler, including green ones, the methods of production, testing, and applications of conductive cement-based composites are addressed and highlighted. Conclusions are made according to the literature reviewed, and some points of view are proposed for future perspectives.


A novel pure electric vehicle with dual motors configuration is introduced.The energy conservation potential and mechanism of this new vehicle are analyzed.First,the structural characteristics and operating mode are investigated.Then the parameters of the powertrain and control strategy are designed.The rationality of the parameters and the validity of the control strategy are demonstrated in MATYLAB/Simulink.As compared to the traditional pure electric vehicle,the energy conservation potential of the new pure electric vehicle with dual motors is around 10%.


The basic DiffServ model lacks the mechanism to prevent itself from being overload; it does not have any capability to inform the edge nodes about the internal traffic load in the network. Thus, injecting more QoS sensitive traffic into the network will not only degrade the performance of the current flow but it will also degrade the performance of already established flows. In this research paper we present an admission control mechanism that establishes QoS enabled Label Switched Paths in-order to provide rigorous QoS provisioning within the DiffServ enabled mobile ad-hoc network. We have presented a scheme that works by merging the signaling overhead with routing. We have performed extensive simulations to measure the effectiveness of our presented idea and we have observed that our scheme meets stringent QoS requirements of real time flows compared to some existent QoS models. Each admitted flow gets low delay, low jitter and almost guaranteed bandwidth. We have also observed that in most of the cases our scheme provides load balancing if multiple path exists to the destination.

In the pumping laser cavity of the intra-cavity KTP optical parametric oscillator (OPO) pumped by the electrooptical-switched Nd:YAG laser, a polarmeter is plugged. When OPO works at high repetition rate frequency, the polarizer will produce depolarization losses because of the thermally induced birefringence in Nd:YAG rod. As a result the pumping laser energy will decrease and the laser beam quality will become worse. OPO output laser energy will fall. To compensae the depolarization losses induced by birefringence, a λ/4 wavelength plate is plugged in the pumping laser cavity. The experimental results show that the output laser energy of OPO with the thermal compensation excesses 20% to that without thermal compensation at high repetition rate frequency.


The chapters in this section look at some of the problems associated with the development of sex robots. In chapter 6, Hertzfeld looks at a variety of objections to sex with robots from a Judeo-Christian perspective, suggesting that the major stumbling block for this religious tradition is the possibility that sex with a robot is less physically and emotionally demanding than sex with a real human being. Danaher follows in chapter 7 by examining the symbolism of sex robots, focusing in particular on what the development of sex robots might say about our attitudes toward sexual consent. He identifies a common argument-structure that is used in the debate about sex robots (the "Symbolic-Consequences Argument") and subjects it to critical scrutiny. Strikwedra closes this section in chapter 8 by considering the important topic of sex robots that are designed to look and act like children. Could they be used to treat and dissuade would-be pedophiles? Strikwerda argues that there is more to be said against the idea than in its favor.


Combined with practical situations in foundation pit construction based upon considerations on safety and economic factors the protection system of excavation sheet pile retaining wall is proposed, which acquired good effects and has a certain reference value for similar work.


The number of rheumatologists in Germany does not cover the minimum medical need [1]. This implies long journeys and waiting periods for patients in the context of rheumatologists' consultations. International studies suggest that telemedicine could resolve these issues and support health care professionals in rheumatologic care [2, 3]. So far, comprehensive sustainable approaches are still pending in Germany. By addressing the potential users, TeleRheumaBB investigates whether and how telemedicine can support rheumatologic care in Germany. The study is realized from Oct. 2017 until Jun. 2020.The objectives of the study are to evaluate the acceptance and willingness of patients and medical practitioners (MP) to implement telemedicine into rheumatological care as well as to understand how telemedical approaches should be designed to be applied in daily practice.The study design contains a mixed-methods approach, which combines qualitative and quantitative data. In the qualitative part of the study 28 in-depth interviews and 3 focus groups involving patients, rheumatologists, general practitioners and stakeholders were conducted. The quantitative part of the study comprised a questionnaire survey with rheumatologists (n=48) and referrers (n=444) and a second questionnaire survey with patients (n=734).Qualitative Data:The term "telemedicine" is filled with different meanings. Motives to implement telemedicine into daily practice are patient guidance, information, substantial time savings, desire of a modern practice etc. Reported risks of telemedicine are adverse impacts on the doctor-patient-relationship as well as low benefit with high effort.Quantitative Data:62% of the MPs' surveyed answered that they would like to use telemedical approaches. 81% of the participants supported doctor-doctor communication via telemedicine. Only 47% of the MPs' surveyed supported doctor-patients communication via telemedicine. MPs' state that there are barriers which prevent them from implementing telemedicine (89%). These are among others acquisition of technology, administrative expenses and poor remuneration.53% of the patients surveyed stated that they had heard the term telemedicine before. 30% of the participants answered that they would like to try out telemedicine. 38% answered with "no" and 29% with "do not know". Further results from the patient survey will be available in June 2020.The study results show high acceptance rates of telemedicine regarding doctor-doctor communication. Doctor-patient communication via telemedicine is less accepted. However, MPs' are reporting obstacles preventing the implementation of telemedicine in rheumatology. In order to implement telemedicine in rheumatological care comprehensively, adequate conditions must be established in the German health care system.[1]Zink A, Braun J, Gromnica-Ihle E, Krause D, Lakomek HJ, Mau W, et al.

The acceptance of renewable energy technologies (RETs) has increased tremendously owing to government policies, sustainable energy development programs and agenda of most independent power providers (IPPs) and private individuals around the world. The potential of RETs can be utilized by the utilities to meet the energy needs of over 1.1 billion people on the global note that do not have access to electrical power supply. As a result of the persistent load growth, it is imperative to plan how RETs can be strategically structured to achieve the optimal operation in the deregulated power sector. The design and planning of RETs in the open market scheme require the technical, environmental and economic analyses of the power system to be implemented. The performance assessment of the power system is carried out in this research work with the application of the HOMER application tool as a measure to optimize the key performance indicators of a microgrid system (MGS) and promote the utilization of RETs for power solutions. A renewable energy-based MGS proposed in the study consists of biogas generator, diesel generator (DG), photovoltaic (PV), battery system (BS) and electrical loads. The system is designed for rural electrification project and to satisfy the load demands of a rural community in accordance to the sustainable energy goals and policies of many international organizations.


El Ejido is located in an area of moderate-to-high seismic hazard in SE Spain. The Multichannel Analysis of Surface Waves (MASW), a non-invasive seismic method, well-suited for urban exploration, has been used in this work to characterize the shallow sediments in this urban area. The performance, as seismic sources, of a sledge hammer and a manual vibratory rammer is compared here. Subsurface materials have been classified in terms of Eurocode-8 soil types to facilitate the implementation of these results in seismic hazard studies.


Spina bifida is one of the disabilities with which teachers in training will normally meet in regular classrooms, for teachers of Fiscal Education becomes a fundamental element of analysis, since the education of this person must be accompanied by plans that allow its integration from the physical and social context.


The protection of privacy under the Indian Constitution, developed through case law by the Supreme Court, has been advanced further by the Delhi High Court's decision to strike down provisions criminalising homosexual sexual conduct on grounds of invasion of privacy (Naz Foundation v Government of NCT of Delhi WP(C) No.7455/2001 (2 July 2009) ('Naz Foundation Case'). The potential for further expansion of constitutional protection of privacy into the area of data protection is increased. The Constitution of India provides that 'No person shall be deprived of his life or personal liberty except according to procedure established by law' (Article 21). The Supreme Court has interpreted this provision to include the protection of privacy since Kharak Singh v. The State of U. P. [1962] INSC 377; 1963 AIR 1295 1964 SCR (1) 332. Privacy was also held to be part of what was protected by Article 19(1)(a) (right to freedom of speech and expression) and Article 19(1)(d) (right of freedom of movement). Article 14's guarantee of 'equality before the law or the equal protection of the laws' is also significant in its interaction with Article 21. The Supreme Court has held that a citizen has a right to receive information, derived from the concept of freedom of speech and expression comprised in Article 19(1)(a) (State of U.P v Raj Narayan (1975) AIR 1975 SC 865; P.V.Narsimha Rao v State (1998) AIR 1998 SC 2120). The protection of privacy by the Indian courts has developed primarily from this constitutional basis, rather than by Indian courts developing a tort of invasion of privacy (as in the USA or New Zealand), or by extension of the law of breach of confidence (as in the UK). The most significant development outside search and surveillance issues is the new decision of the High Court of Delhi in the Naz Foundation Case (2 July 2009). The case was public interest litigation brought by the NGO, Naz Foundation to challenge the constitutional validity of Section 377 of the Indian Penal Code, 1860 (IPC), which criminally penalizes what is described by the section heading as 'unnatural offences' ('Whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal …'), therefore in the Court's interpretation effectively criminalising sex other than heterosexual penile-vaginal. The Delhi High Court initially dismissed the application as an 'academic challenge', but was required by the Supreme Court in 2004 to re-examine the matter. This article examines the reasons why the Court held that s377 violated Articles 21, 14 and 15 of the Constitution, insofar as it criminalises consensual sexual acts of adults in private. The Naz Foundation Case therefore takes the protection of privacy under the Indian Constitution beyond issues of search and surveillance. The broadest statement of the Delhi High Court's approach is where, following its review of Indian case law to date on protection of privacy, it states 'The right to privacy thus has been held to protect a "private space in which man may become and remain himself". The ability to do so is exercised in accordance with individual autonomy'. If such an expansive approach was adopted by the Indian Supreme Court, it is capable of developing in the direction of something like the 'right to informational self determination' of the German Constitutional Court.


We analyze the ability of a term with a popular social denotation to function as a medical term. This is an indicator of eurysemy, which can be traced by means of fixing these two aspects of word usage and methodically used to optimize the learning process in a medical institution of higher education.


An intelligent therapeutic approach to the problem of menometrorrhagia will result only when the mechanism of uterine bleeding is fully understood. The artificial induction of pseudomenstrual bleeding in the castrated human female clarifies many controversial points. The data on the case to be reported has been charted in figure 1. case report Z.M.D., a white female, 28 years of age, presented hep self at the Endocrine clinic of the University Hospital during the latter part of 1939 complaining of severe menopausal symptoms. One year previously she had been submitted to laparotomy and both fallopian tubes and ovaries were removed because of tubo-ovarian abscesses. From Nov. 14 to 16, 1939, a 48-hour urine specimen was obtained and the urine was found to contain an insufficient amount of estrogen for assay.

Users can utilize powerful computing resources in cloud computing, which brings users great convenience. However, cloud computing is also facing many challenges for data security as the users outsource their sensitive data to clouds, which are generally beyond the same trusted domain as data owners. To address this problem, access control, which grants access permissions to an authorized user, is considered as one of critical security mechanisms for data protection in cloud computing environment. However, due to the unpredictability of user identities and access behavior, access control in cloud computing has become a key security problem. In this project, we propose a self-adaptive access control model based on secure cloud computing environment. The secure cloud computing environment includes analyzer Engine, Detection Engine, Rollback Engine, execute parts and knowledge base, and the knowledge base is used to make decisions on access requests. We also propose our own algorithm to create the Secure Engine. The self-adaptive access control model based on Secure Cloud Computing Environment we proposed can be applied to cloud computing environment.


Protected areas play a critical role in biodiversity conservation in the Democratic Republic of Congo. However, they are under anthropogenic pressure. The study was carried out in the Bombo-Lumene reserve situated in Kinshasa, DR Congo. A questionnaire-based survey was conducted to determine the causes underlying ecosystem degradation and biodiversity loss and the determinants of the willingness of the population to participate in collaborative management with the State. Logistic regression was used to check the determinant factor. Findings showed that farming, charcoal production, and poaching are the direct causes of ecosystem degradation and biodiversity loss. The indirect cause is land confiscation, which causes conflicts between the local population and the State. Consequently, the majority of the respondents are not will-ing to participate in collaborative management. Results of logistic regression indicated that level of education was the only explanatory factor that deter-mines the willingness to participate in collaborative management with the State.


This article examines how investor sentiment affects stock returns on Vietnam's stock market. Investor sentiment index is measured by a relative strength index (RSI) of 57 companies listed on the Ho Chi Minh Stock Exchange from January 1, 2015 to July 31, 2020. Control variables include investors' stock trading behavior, firm size, and cash flow per share. Using Fama-MacBeth regression estimation and general least square estimation (GSL) on a daily basis, both methods find the sentiment of high investors producing higher stock returns, on the contrary, the sentiment of low investors erodes stock returns. Different from the results of Brown and Cliff (2004) [Brown, G. W., & Cliff, M. T. (2004). Investor sentiment and the near-term stock market. Journal of empirical finance, 11(1), 1-27], the article found that the investor sentiment factor plays the most important role in explaining the return of the stock market compared to the rest of the factors.


When mounted on the same side as the inspiratory port, the breathing circuit support arm used with the Maquet Servo-i ventilator can be positioned in such a way that it compresses the circuit's inspiratory limb, restricting gas flow to the patient. (This problem is possible only on the mobile cart configuration.) Users can avoid this problem by securing the arm above the port or by mounting it on another side of the ventilator.

On the occasion of the 60th birthday of Prof. Ghurye, the Economic Weekly (19th Dec. 1953) wrote, "Few are competent in this country or abroad to assess the contribution of Prof. G. S. Ghurye in the wide field which he has traversed with such conspicuous success in the 60 years of his life....." The range of Ghurye's interest is encyclopaedic. From Shakespeare to Sadhus, from art and architecture to folk-gods and goddesses, from sex and marriage to race relations Ghurye had made his peregrination, took interest in and left his mark on, the multiple aspects of what may broadly be called 'culture'. The time span and the area which he covers in the process is equally impressive. His abiding in-


An inventory management is technique which is generally used to manage the organization effectively. The organization wants to control their inventory cost, material cost, labor cost etc. There are several inventory techniques used in organization such as XYZ, ABC, HML, VED and S-OS. In this study we shall focus on XYZ analysis. In XYZ analysis the items are classified into X, Y and Z classes based on unit demand variability. The variability of items is measured by the coefficient of variation (CV) Data collection is mainly of 3 months through the general store manager and other staff involved in inventory control operation of steel plant.

e16080 Background: Phase 3 trials of abiraterone acetate plus prednisone (AA+P) or enzalutamide (ENZ) in asymptomatic/mildly symptomatic chemotherapy-naive mCRPC patients demonstrated significant improvement in overall survival (OS). Clinical trials comparing the magnitude of OS benefit for AA+P to ENZ have not been completed. In the absence of head-to-head trials, indirect comparisons may be used to assess the cost effectiveness of these agents in mCRPC. To calculate the cost per median OS month in asymptomatic/mildly symptomatic chemotherapy-naive mCRPC patients treated with AA+P or ENZ. Methods: Median treatment duration and median OS data from published phase 3 trials and prescribing information (PI) were used to calculate cost per median OS month based on Wholesale Acquisition Costs (WAC) effective on 8/5/2014 for mCRPC patients treated with AA+P versus ENZ. Sensitivity analyses were performed to understand how variation in treatment duration and treatment-related monitoring recommendations influence...


To develop the waste water solutions challenging task. To design sustainable wastewater solution requires information about new ideas, new systems and latest technology.

The issue of growth management in urban settings has captured the attention of concerned groups for the past several decades. The voice that is sometimes lacking is that of the residents of neighborhoods who are inevitably affected by the economic and political decisions made by others on how and where growth should occur, but whose recommendations are often ignored or overturned. In an attempt to determine resident satisfaction with the growth management policies promulgated by urban decision makers, the researcher examined association newsletters from 44 neighborhoods in Albuquerque, New Mexico. Results of this study indicated that community satisfaction with growth management does not show a consistent pattern. What did emerge, however, was the fact that neighborhood residents want more information about growth management strategies and more involvement in the land use decision making process.


Analysis of the processing equipment structures when designing according to the temperature criterion is a necessary guarantee of ensuring the required performance characteristics. The presence of a significant number of parts in the processing equipment units and mechanisms requires, when designing, the prediction of the heat flow passage through the joints. When simulating contact thermal resistance, the variety of requirements for a joint can be taken into account by introducing a pseudolayer into the contact zone. The paper presents test results of the proposed regression dependence of the temperature change when the heat flow goes through the pseudolayer obtained considering four significant factors: the pseudolayer thickness, the nominal pressure, the material yield strength, and the actual contact zone location. The adequacy of the specified regression dependence was verified experimentally and applying numerical simulation using large-block finite elements. To describe the process of heat transfer in the thermal model elements, the authors determined contact thermal resistances for several conditions for the heat flow propagation: from one finite element to another within one part; from one finite element to another located in an adjacent part; heat flow passing through closed cavities; heat flow propagation into the environment for finite elements located on the outer (free) contour of the part. The experiments showed a good agreement between the experimental data and the simulation results. The application of large-block finite elements based on the proposed contact thermal resistance model allowed bringing the FE simulation technique to engineering use without complex software.


The fabrication of overgrown silicon permeable-base transistors (PBTs) is described starting from MBE-grown epitaxial Si/CoSi/sub 2//Si heterostructures. Gate fingers are patterned by Ar sputtering followed by low-pressure vapour phase epitaxial overgrowth at 800 degrees C and 0.2 mbar. Results on surface morphology, Schottky-diode characteristics, and PBT performance are presented. It has been recognized that a serious problem of Si PBTs is the field crowding effect at the rim of the thin silicide gate. It cases breakdown at low voltages and limits PBT performance. A diagram indicating the possible operating areas depending on silicide thickness, channel doping, and PBT geometry is presented. >

Based on the two-dimension theory, a computer code is made in FORTRAN language to design the high specific speed mixed-flow pump. The theory and method in calculating meridional velocity distribution by streamline iteration, drawing blade shape by point-by-point integration, thickening blade and smoothing leading edge and trailing edge of the blade by conformal mapping are introduced. The effects of several parameters on the designed impeller shape are also discussed, including hub/shroud radius ratio, velocity moment distribution function on the meridional streamline, position of blade inlet and outlet edge. This computer code can increase the efficiency of design work and the accuracy of calculating results. The data of the blade's surface is complete which is convenient for blade manufacturing by numerical control machine. It provides a useful tool for designing the impeller of high specific speed mixed-flow pump.


Abstract The binomial formula which was given by Cox et al. is a tool for valuating the European call option. We know that it converges to the Black–Scholes formula which was given by Black and Scholes as the number of periods (n) converges to infinity. In 1988, Boyle introduced the trinomial formula to be another tool for calculating the European call option. In 2013, Entit et al. considered the trinomial formula in case that the rate of a stock price rising is and the rate of a stock price falling is where T is maturity time, σ is volatility and They gave examples to show that the value of European option from their model is closed to the value from the Black–Scholes formula. In this paper, we give the rigorous proof of this conjecture by showing that the trinomial formula converges to the Black–Scholes formula.

One classifies the globally generated vector bundles on Pn with the first Chern class c1 = 3. The case c1 = 1 is very easy, the case c1 = 2 was done in [42], the case c1 = 3, rank =2 was settled in [21] and the case c1 ≤ 5, rank = 2 in [10]. Our work is based on Serre's theorem relating vector bundles of rank = 2 with codimension 2 lci subschemes and its generalization for higher ranks, considered firstly by Vogelaar in [48].


Corrosion behavior of galvanized steel wires of bridge cables in a simulated acid rain environment was studied by means of salt spray test and RH402 hydrogen analyzer,and then corrosion products were characterized by XRD.Results showed the zinc coating of steel wires located at the periphery of cables was exhausted locally by salt spray test for 2.5 months.The main corrosion products were mainly consisted of 3Zn(OH)_2·ZnSO_4·5H_2O,and ZnSO_3·2H_2O plus Fe_6(OH)_(12)CO_3 respectively for wires exposed for 2 and 3 months.Finally a three-stage process was proposed to describe the corrosion of steel wires in simulated acid rain.


The changes of plastic deformation parameters (yield stress σy, deformation stress σe ) for the NaCl crystals doped with different two-valent impurities (Mg, Mn, Pb, Cd, Sr, Ca) for the high temperature region (T>293K) were investigated. The anomalous region, suitable for the yield stress increase, but not the regular decrease, on the σy(T) dependences at the high temperatures was revealed. Analogous phenomenon occurs for the σe too. It was first established that the anomalous hardening of doped NaCl crystals at elevated temperatures is dependent on the type, concentration and state of impurity, on the temperature and rate of deformation and is connected with the value of the impurity hardening. The interpretation of the experimental facts and phenomena was proposed.

Materials AbstrA ct Purpose: The paper presents physicochemical properties and biomechanical analysis of fixation plates made of Cr-Ni-Mo stainless steel used in the funnel chest treatment. Design/methodology/approach: The corrosion tests were realized by recording of anodic polarization curves with the use of the potentiodynamic method. The VoltaLab® PGP 201 system for electrochemical tests was applied. The numerical analysis was performed for: the stabilizer of 460 mm length, 16 mm width and 4.5 mm thickness, the stabilizer of 460 mm length, 16 mm width and 3.5 mm thickness, the stabilizer of 460 mm length, 16 mm width and 2.5 mm thickness. Findings: The tests showed that structure of the steel the plates were made of, met the PN-ISO 5832-1 standard. The surface damage is induced in the given deformation regions and is a potential reason of corrosion. The numerical analysis shows that stresses in plates didn't exceed the yield point: for the stainless steel Rp0,2min = 590 MPa. Values of maximum displacements occuring in the stabilizing bar in the range of clinically acceptable displacements. Research limitations/implications: The obtained results are the basis for the optimization of physicochemical and mechanical properties of the metallic biomaterial. Practical implications: On the basis of the obtained results it can be stated that that stainless steel can be applied in the funnel chest treatment. Originality/value: The paper presents the influence of surface damage and stresses and displacement of plates used in the funnel chest treatment on the corrosion resistance.


This paper emerges from a study carried out to explore ways of how professional development can be conducted to help Home Economics (HE) teachers introduce technology effectively as a pedagogy. This research attempts to build a bridge between educational technology and Home Economics (HE) teachers. It will show how one can support teachers in integrating educational technologies effectively and give appropriate examples of how classroom practice can be improved for the 21st-century learner. An online community was used with teachers of HE in order to diffuse this innovation and offer ongoing support. Rogers' (2010) model provided a structure for this dissemination process. A questionnaire was used to achieve the overall interpretation of the impact of the CoP on the knowledge of teachers' use of technology for HE and to identify how effective the Community of Practice (CoP) was. The discussion fora were analysed to bring out the teachers' reactions. Interviews were then used to ensure validity and depth of interpretation. The main findings show that the CoP was effective in making the teachers aware of innovative pedagogies, and how to use technology effectively. They also developed favourable attitudes towards technology. However, the interaction was poor as the virtual activity progressed which shows that the participants preferred to receive inofrmation rather than share it, that time might be a barrier worth addressing and that the transformation to a tech-savvy teacher might not take place unless there is ongoing support.

We use firm-level data on Swedish multinationals to analyze how the recent expansion of affiliate employment in Central and Eastern Europe (CEE) has affected affiliate employment elsewhere. According to our results, employment in affiliates located in other low-wage countries in Europe decreased substantially as a consequence of the expansion in CEE. Furthermore, affiliate activities in these countries have become more sensitive to changes in labor costs as firms have set up production in CEE. We find that employment in Sweden and other high-wage European countries has also been affected, but these effects seem to be much smaller.


SUMMARY

A method of prediction of perceptibility of luminous-transmittance and dominant wave-length differences by spectrophotometric measurements is given for a small area of the color continuum with a specific product. Graphs are presented from which the dominant wave-length or luminous-transmittance differences necessary for discrimination are read directly, at various probability levels of success, for any dominant wave length or transmittance over the range of red wines.


Fullerenes, the symmetric allotrope of carbon with bucky ball structure is gaining high magnitude of interest in material chemistry as well as in medical scheme. Fullerenes find its role in batteries, solar cells, for hydrogen storage, trapping reactive species, as lubricants, MRI contrast agents, protective coatings, superconductors and also in biomedical applications as neuroprotective agents, anti-oxidant, enzyme inhibitor, delivery vector, biosensor, for photodynamic therapy etc. Apart from the intentional exposure during usage in various applications, nano fullerene mixture is present in automobile/industrial exhaust, release from incomplete combustion of fossil fuels etc. Increased exposure entail the exigency for toxicity profiling of fullerene. Inhalation being a major route of nanoparticle exposure compels lungs at high risk of toxicity due to accumulation. Retention at the "alveoli site" potentially causes translocation into blood that further complicates the scenario. Improved perception on the effect of nano fullerene mixture on lung cells is needed to make a critical inference.


In this paper, we propose a new map-based collaboration environment 'MapWiki' for ubiquitous content distribution. In MapWiki, users can publish Wiki contents which contains links or inline images of the objects in the ubiquitous environment by simple formatting rules. The status change of the content are updated on the map in real-time which enables users to communicate between real field and virtual environment. Publishers and receivers are authenticated using social network to ensure the trustfulness of the content. We implemented MapWiki mechanism on Google Maps and evaluated its feasibility and usefulness.


In recent years, the inertial measurement unit (IMU) had been widely used in precision sports and biomechanics for movement analysis and evaluation. A novel algorithm has been derived to detect countermovement jump height in real-time and achieve a mean error of 0.1 cm compared with commercial 3D tracking systems. In addition to sports ability, the correlation between IMU and various neurological diseases can also assist in diagnosing and rehabilitation for epilepsy, Parkinson's disease, and dementia.Implemented with TSMC 0.18 μm process, the algorithm is also proved to be power-efficient and area-efficient for wearable applications. To achieve a low power design, set the clock frequency to 6.5 kHz. The highest operating frequency is 22 MHz, the power consumption is 13.5 mW at 40 kHz, and the chip area is 1.153 mm by 1.150 mm. Furthermore, an application on Android Studio is also developed to demonstrate the jump height estimation algorithm for real-time applications.

We present a simple toy model for colour reconnections at the nonperturbative level. The model resembles an annealing-type algorithm and is applicable to any collider and process type, though we argue for a possible enhancement of the effect in hadron-hadron collisions. We present a simple application and study of the consequences for semileptonic t{bar t} events at the Tevatron.


Remarkable progress has been brought about in the study of the cerebellar cortex. Functional analysis of the neuronal elements in this region of the CNS has been done in detail in conjunction with electron microscopic investigations. The recently published monograph on the cerebellum by ECCLES, ITOH, and SZENTAGOTHAI (1967) has shed light on the study of this rather neglected area of the CNS. Neurons, interneurons and axons have been analyzed in detail and identified on the combined grounds of ultrastructure and electrophysiology. The architectural design of the cerebellar cortex has been brought to the utmost clarity owing to the strenuous efforts of many workers in this field; among others, SZENTAGOTHAI and his associates have contributed most to the study of the cerebellar structure. The efferent and afferent fiber connections were well analyzed on the ground of the findings of light and electron microscopy. The well designed degeneration experiments of HAMORI (1964) and SZENTAGOTHAI (1965) have much clarified the situation which had remained ambiguous so far. Functional analysis has been done electrophysiologically with brilliant success by ECCLES (1965), ECCLES and his associates (1964, 1966 a, b, c). The excitatory and inhibitory nature of each neuron in this complicated nervous system has been proposed on the basis of the analysis of electrical events of neurons. A new hypothesis has been proposed by the present author which enables us to distinguish excitatory and inhibitory synapses morphologically (UCHIZONO 1965, 1966, 1967 a, b). This paper concerns mostly with the axon identification based on Sand F-type synapse (UCHIZONO, 1965, 1966, 1967 a, b) in the cerebellar cortex.


Abstract Objectives Missing data are a frequent and unavoidable challenge in bioarchaeological research, yet researchers seldom make explicit statements about the bias and inferential limitations that missing data introduce into their studies. There are no guidelines for best practices for the treatment or reporting of missing data. As an initial step in taking stock and exploring approaches to missing data in bioarchaeology, this study reviews bioarchaeological publications to identify methods currently in use for addressing this significant problem. Materials and Methods Over 950 bioarchaeology articles (2011–2020) from four major anthropology journals were surveyed, searching for the terms "missing," "absent," "unobserv," "replace," and "imputat." The 267 articles so identified were categorized into one of nine bioarchaeological subtopics and scored according to a set of six broad approaches for handling missing data. Results Results indicate that bioarchaeologists handle missing data in a variety of ways. Methods such as antimere substitution, listwise deletion and pairwise deletion are widely used. Subject subtopics favor different techniques for handling missing values. Bioarchaeological articles categorized as archaeology, pathology, and trauma used basic missing data approaches, while those such as biodistance and morphology more often employed advanced statistics. Despite the ubiquity of missing data, considerations of how they introduce bias were uncommon and standards for reporting were inconsistent. Conclusions These findings highlight areas in which bioarchaeologists can improve techniques for handling and reporting missing data. Greater attention to these shortcomings will increase the statistical rigor of the field.


Halfway through post's production of Oedipus Schmoedipus , performer Mish Grigor drags a dead body across the stage. Mish delicately arranges the body, that of a volunteer performer who has been 'playing dead', into a kind of deformed pieta , cradled across the arms and lap of fellow performer Zoe Coombs Marr. Mish is supporting the back of the body's head, and stroking her arm lovingly. 'So the greats tell us that when you're dead', begins Zoe, before she is cut off by a sharp laugh from the audience. 1 She looks down to find that the body in her arms, trembling almost imperceptibly, has begun to smile. She tries again, 'that when you're dead ', slapping the body lightly across the face, only to have the body upstage her once more by breaking into a wide grin. Zoe angles her head down and continues her line straight into the body's ear: 'it's just like being asleep. And dreaming'. The body behaves, the laughter dies down, and the show continues.


The thesis deals with the question of the intercultural relations, the search for identity and the place of immigrants in the Canadian society, and it is particularly focused on the immigrants of the Jewish origin. Firstly, the history of immigration and multiculturalism in Canada in general are presented; afterwards, the present study focuses on the history of the Jews settled in this country. It is followed by the discussion of the way in which the phenomenon of the immigration, including the arrival of the Jews to Canada, is depicted in French-Canadian literature. One part of the thesis concentrates on the explanation of the terms "cultural identity", "otherness" and "Jewishness/Judaism", which play an important role in the thesis. The aim of the thesis is to depict the image of the Jew in the Quebec Novel through the analysis of the three works dealing with Jewish characters: Aaron by the Quebec author Yves Theriault, Alexandre Chenevert by the Franco-Manitoban writer Gabrielle Roy and L'Apprentissage de Duddy Kravitz by the Canadian-Jewish author Mordecai Richler. The crux of the thesis called "The Image of the Jew in the Quebec Novel" is formed by the themes such as the process of integration into the different society and the difficulties connected with it, the loss of the former identity, the influence of modernity and multiculturalism on the fortunes and behaviour of the Jewish immigrants.


As of the year 2000 in Korea, there are as many as 19 tourism societies similar in nature, including the oldest mother society, The Tourism Science Society of Korea (TOSOK). Excessive fragmentation to pieces of the societies might raise various problems including a membership feeling of indignity suffering from academic degradation, a gradual loss of external competitiveness and so on. To tackle these problems author conducted an e-mail survey to the existing academic members on how to do. Based on the survey he suggests to establish four to five branch chapters while addressing some principles conducive to both parties.


As the most violent large-scale explosive phenomenon in the solar atmosphere, coronal mass ejections (CMEs) are the main source of disastrous space weather in our solar-terrestrial environment. Detailed evolution of the toroidal magnetic flux inside CME flux ropes is still poorly understood. Recently, researchers from Nanjing University developed a new method to achieve a better identification of the footpoint regions of erupting CME flux ropes. Applying this new method, they successfully obtained and further quantitatively investigated the evolution of toroidal flux of four erupting flux ropes. They found that the toroidal flux of CME flux ropes experiences a rapid increasing phase followed by a decreasing phase. Such a two-phase evolution of toroidal flux is generally synchronous with the energy release process in CME-associated solar flares. This study provides a quantitative assessment of the variation of the toroidal flux of CME flux ropes during their eruptions, which is of vital significance for understanding the three-dimensional nature of CMEs.

Low birthweight is associated with increased risk for cardiovascular disease (CVD) in later life, but whether premature birth is also a risk factor for CVD has not been fully determined. The aim of this study was to investigate the relationship between gestational age and risk factors for CVD at school age.


. Subduction zones represent the only major pathway by which continental material can be returned to the Earth's mantle.

When the viscous coupling is increased, an erosive style margin will be favored over an accretionary style. On the other hand, when the viscous coupling is reduced, sediments are scrapped-off the subducting slab to form an accretionary wedge. ::::::::::: :::::::: sediments ::: ::::::::: large-scale subduction dynamics. been important :::::: density :: of ::::::::: sediments, : age of slab, thermal structure, upper plate structure) that will be discussed below.


A simple and sensitive method was established for the separation and detection of 6 organic acids (oxalic acids,tartaric acid,malic acid,formic acid,succinic acid and acetic acid) by nonsuppressed ion exclusion chromatography with conductometric detection. The effect of benzoic acid concentration,flow rate and column temperature on the separation of organic acids was investigated by using Ion Pac ICE-AS6 as analytical column and diluted benzoic acid of lower background as eluent. Through the test,the optimal separation of six organic acids was achieved with 1.0mmol/L benzoic acid solution as the eluent at a flow rate of 0.45 ml/min,and column temperature at 35℃. Detection limits for the organic acids ranged from 0.0341 to 0.9045 mg/L,the relative standard deviations were between 0.13% and 5.12%,and the recovery rates were between 90.75% and 108.5%,the measuring method was provided with better accuracy and precision. The organic acids in 23 Jiangxi wine samples from the five different manufacturers were analyzed with satisfactory results.

In the construction period of Baiyekou Reservoir's concrete facing rockfill dam,it was possible that the water level in dam body would be higher than the water level in downstream foundation pit,it would lead to backword seepage through bedding on dam slop toward upstream,to destroy bedding layer,extrusion side wall and to bring difficult for construction of toe slab,consolidation grouting and curtain grouting.Therefore,dam body drainage during construction period is vital important.The paper introduces the layout of dam body drainage,the main drainage methods,the protection of backword drainage in construction period,and how to close the drainage pipe at the end.


Much has been written about the links between poverty and physical health as recognised by the Human Rights and Equal Opportunity Commission (2008) in Close the Gap. Much less has been written about the links between financial (or economic) status and mental health. This paper seeks to bring together some of the literature available on Aboriginal and Torres Strait Islander people and emotional wellbeing with a particular focus on the impact of financial stress caused by consumer issues. In 2010 a report published on the law relating to unconscionable conduct and Aboriginal and Torres Strait Islander consumers (Loban, 2010) found an important legal issue for Aboriginal and Torres Strait Islander people was the lack of legal protection from the unfair practices of businesses. This paper will show that whilst consumer protection is primarily a legal problem there is a vital role for health professionals to play in relation to the emotional wellbeing of Aboriginal and Torres Strait Islander people suffering financial stress as a result of rogue traders.


The kinetic study of 3-chloroacetylacetone and thioureas has been carried out in ethanol. Thioureas used for study are thiourea, phenyl thiou rea, p-methyl phenyl thiourea, p-ethoxy phenyl thiourea and p-chlorophenyl thiourea. The se cond order rate constants for these reaction were reported. The rate of reaction is first order with respect to 3-chloroacetylacetone and first order with respect to thioureas. The effect of subs tituents on the rate of reaction was also studied. Thermodynamic parameters are used to explain the nature of the reaction. The reaction products are isolated and characterized. Possible reaction m echanism for the reaction will be proposed and details of the kinetics will be discussed.


Graphene has emerged as the foremost material for future two-dimensional spintronics due to its tuneable electronic properties. In graphene, spin information can be transported over long distances and, in principle, be manipulated by using magnetic correlations or large spin-orbit coupling (SOC) induced by proximity effects. In particular, a dramatic SOC enhancement has been predicted when interfacing graphene with a semiconducting transition metal dechalcogenide, such as tungsten disulphide (WS$_2$). Signatures of such an enhancement have recently been reported but the nature of the spin relaxation in these systems remains unknown. Here, we unambiguously demonstrate anisotropic spin dynamics in bilayer heterostructures comprising graphene and WS$_2$. By using out-of-plane spin precession, we show that the spin lifetime is largest when the spins point out of the graphene plane. Moreover, we observe that the spin lifetime varies over one order of magnitude depending on the spin orientation, indicating that the strong spin-valley coupling in WS$_2$ is imprinted in the bilayer and felt by the propagating spins. These findings provide a rich platform to explore coupled spin-valley phenomena and offer novel spin manipulation strategies based on spin relaxation anisotropy in two-dimensional materials.


We analyze the Cauchy problem for non-stationary 1-D flow of a compressible viscous and heat-conducting fluid, assuming that it is in the thermodynamical sense perfect and polytropic. This problem has a unique generalized solution on R×]0, T [ for each T > 0. Supposing that the initial functions are small perturbations of the constants and using some a priori estimates for the solution independent of T , we prove a stabilization of the solution.


There was a substantial fall in older British employees' wages and earnings, relative to younger employees, over the 1990s and 2000s. This shift in the lifetime fortunes of employees was possibly stimulated by pressures of increased competition, and intensified technological and organisational change, along with the high cost to employers of elder employment. A panel analysis for the period 1990–2006 shows that older (age 45‐plus) employees in non‐union jobs fared much worse, in terms of relative pay, than did those in unionised jobs. Unions were partially successful in maintaining the relative pay of older employees, compared with younger employees, and this applied to both older female and older male employees.


The aim of this work was to define three-dimensional (3D) non-rotational aspherical parametric models for the human cornea and lens using computational geometry and CAD representations. The hyperbolic cosine based function is used for the cornea and a parametric model is used for lens modeling. Data analysis and visualization of 3D non-rotational models were made using the Rhinoceros CAD software and MATLAB software was used for numeric computation. We combined, implemented, and evaluated these models with a 3D ray-tracing in order to fully analyze the human eye model. It was found that 3D non-rotational aspherical models for the human eye could be more accurately modeled and rendered for analysis with finite element method. The objective of this study is to present and analyze mathematical models of the cornea and lens and to highlight the potential of optical applications of the eye models containing astigmatic surfaces, which are more close to the real eye than spherosymmetric eye models.


A highly precise vertical turntable provided with hydrostatic bearings and radial runout error compensator has been developped. The compensator has two functions of a closed loop differential hydrostatic actuator for positioning a spindle to a nanometer accuracy and a datum roundness error measuring instrument with multiple position sensors. By separating the datum error from the runout error readings, the compensator can overcome the limitation of geometrical datum accu racy. Design philosophy of the turntable spindle system is as follows : (1) Isolation of disturbance sources within the system. (2) Design procedure of bearing pads taking into consideration of the performance of servd valve. (3) Introduction of microprocessor for separating the datum error in rounout error measurment from the runout error readings. Several test results are concluded as follows : (1) The bearing pad dimensions are determined in connecting with servo valve characteristics. (2) The positioning resolution is at least 1 nm and the bandwidth is 250 Hz. (3) Two point roundness measurement method has proved that the compensation accuracy is ± 4.5nm (3 σ). However, correcting the datum error in accordance with the measurement principle, compensation accuracy improved to 6.1nm (2LSB, 5rpm) or 9.15nm (3LSB, 30rpm) in peak to valley.


Monodisperse spherical architectures consisting of MoO 2 nanoparticles and polydopamine-derived carbon matrices are designed and successfully synthesized. X-ray diffraction revealed that the MoO 2 nanoparticles are crystalline state whereas the carbon matrices are amorphous. The hierarchical morphology is confirmed by scanning electron microscope and transmission electron microscope. Electrochemical characterizations demonstrate that the composite can achieve fast K-ion storage, which enable its potential application in K-ion batteries. For optimizing the synthesis condition, different calcination temperatures are adopted. The sample synthesized at 500 o C exhibits the highest capacity in K-ion storage, as well as the best rate capability. Furthermore, study on the kinetics of electrode process reveals that the unique architecture shows significant capacitive behavior, verifying the fast K-ion storage capability.


The dynamic rhythm of life in a modern megalopolis and the socio-cultural context of the countryside determine differences in the lifestyle, culture, worldview of townspeople and rural residents. The low rhythm of life, a fusion of work and everyday life, continuity of traditions and value systems are characteristic of rural residents. It acts as a psychological resource for coping with difficult life situations, including the situation of cancer. The article aims to study the features of subjective control of patients with cancer in the industrial metropolis and rural areas. The study involved 80 women with breast cancer living in the city of Chelyabinsk and rural settlements of the Chelyabinsk region, who are hospitalized at the Chelyabinsk Regional Clinical Center for Oncology and Nuclear Medicine. According to the data obtained, the inhabitants of rural areas interpret significant life events occurring with them as a result of their activities, and not of the prevailing circumstances. They tend to take responsibility for their achievements and failures, and for the events of their family life. The revealed differences in the peculiarities of subjective control in patients with cancer living in an industrial metropolis and rural areas serve as the basis for the development of a system of psychological support for patients with malignant neoplasms.


Theorem provers have highly complex interfaces, but there are not many systematic studies of their usability and effectiveness. Specifically, for interactive theorem provers the ability to quickly comprehend intermediate proof situations is of pivotal importance. In this paper we present the (as far as we know) first empirical study that systematically compares the effectiveness of different user interfaces of an interactive theorem prover. We juxtapose two different user interfaces of the interactive verifier KeY: the traditional one which focuses on proof objects and a more recent one that provides a view akin to an interactive debugger. We carefully designed a controlled experiment where users were given various proof understanding tasks that had to be solved with alternating interfaces. We provide statistical evidence that the conjectured higher effectivity of the debugger-like interface is not just a hunch.


Photocatalysis is an effective technology for NO removal even at low concentrations in the ambient atmosphere. However, the low efficiency of this advanced process and the tendency of producing toxic byproducts hinder the practical application of photocatalysis. To overcome these problems, the Bi@Ba2TiO4/BaBi4Ti4O15 photocatalytic composites were successfully prepared by a one-step hydrothermal method. The as-synthesized photocatalysts exhibited an efficient photocatalytic performance and generated low amounts of toxic byproducts. X-ray diffraction studies show that Bi3+ is successfully reduced on the surface of Ba2TiO4/BaBi4Ti4O15 (BT/BBT). After L-Ascorbic acid (AA) modification, the photocatalytic NO removal efficiency of Bi@Ba2TiO4/BaBi4Ti4O15 is increased from 25.55% to 67.88%, while the production of the toxic byproduct NO2 is reduced by 92.02%, where the initial concentration of NO is diluted to ca. 800 ppb by the gas stream and the flow rate is controlled at 301.98 mL·min−1 in a 150 mL cylindrical reactor. Furthermore, ambient humidity has little effect on the photocatalytic performance of theBi@Ba2TiO4/BaBi4Ti4O15, and the photocatalyst exhibits excellent reusability after repeated cleaning with deionized water. The improved photocatalytic effect is attributed to the addition of AA in BT/BBT being able to reduce Bi3+ ions to form Bi nanoparticles giving surface plasmon effect (SPR) and generate oxygen vacancies (OVs) at the same time, thereby improving the separation efficiency of photogenerated carriers, enhancing the light absorption, and increasing the specific surface areas. The present work could provide new insights into the design of high-performance photocatalysts and their potential applications in air purification, especially for NO removal.


CONCEPT GRAPHS: APPLICATIONS TO BIOMEDICAL TEXT CATEGORIZATION AND CONCEPT EXTRACTION by Said Bleik As science advances, the underlying literature grow s rapidly providing valuable knowledge mines for researchers and practitioners. The text content that makes up these knowledge collections is often unstructured and, th us, extracting relevant or novel information could be nontrivial and costly. In addi tion, human knowledge and expertise are being transformed into structured digital infor mation in the form of vocabulary databases and ontologies. These knowledge bases hol d substantial hierarchical and semantic relationships of common domain concepts. C onsequently, automating learning tasks could be reinforced with those knowledge base s through constructing human-like representations of knowledge. This allows developin g algorithms that simulate the human reasoning tasks of content perception, concept iden ification, and classification. This study explores the representation of text docu ments using concept graphs that are constructed with the help of a domain ontology. In particular, the target data sets are collections of biomedical text documents, and the d omain ontology is a collection of predefined biomedical concepts and relationships am ong them. The proposed representation preserves those relationships and al lows using the structural features of graphs in text mining and learning algorithms. Thos e features emphasize the significance of the underlying relationship information that exi sts in the text content behind the interrelated topics and concepts of a text document . The experiments presented in this study include text categorization and concept extra ction applied on biomedical data sets. The experimental results demonstrate how the relati onships extracted from text and captured in graph structures can be used to improve the performance of the aforementioned applications. The discussed techniqu es can be used in creating and maintaining digital libraries through enhancing ind exing, retrieval, and management of documents as well as in a broad range of domain-spe cific applications such as drug discovery, hypothesis generation, and the analysis of molecular structures in chemoinformatics.

In an earlier work, the possible holonomy groups of all compact locally irreducible Riemannian manifolds of dimensions up to ten were classified, placing particular emphasis on the non‐simply‐connected case. In this work, the problem of finding examples of manifolds with such holonomy groups is discussed. It is proven, in particular, that it is possible to find (Einsteinian) examples of every one of the 23 holonomy types corresponding to manifolds of dimensions less than 7: Thus, an exact characterization of the groups that can occur as holonomy groups can be given in those dimensions.

License plate binarization is a necessary step in the processing license plate recognition,after the license plate has been located and segmented exactly. Generally,Bernsen algorithm,Ostu algorithm and LEVBB algorithm are used for the license plate binarization. However, because of the deficiency in illumination and all kinds of pollution and defile,the above algorithms can not obtain good results.For this,this paper puts forward a new license plate binarization algorithm based on the features of characters' strokes.Quantities of experiments have indicated that the algorithm can overcome the problems and all kinds of pollution,and extract the character target exactly.


ABSTRA C T We have observed variations in the optical emission lines from the X-ray binary Circinus X-1. These variations may be attributed both to orbital variations and to long term secular changes in line strength. We have detected double-peaked Ha emission lines on two occasions, providing the first direct evidence for an accretion disc in the system. The separation of the peaks was different on the two occasions, suggesting that the disc might have a different size. The equivalent width of the emission lines dropped by more than a factor of three between 1999 and 2000; this continues the trend seen in earlier data, so that the Ha equivalent width has now declined by a factor of 20 since 1976. The emission lines do not appear to show signature of orbital motion, except for the data taken near phase 0, which show a significant velocity shift. We have observed an absorption component to the He I lines on one occasion. We suggest that, unlike the P Cygni profiles seen in X-ray spectra, this absorption does not arise in the accelerating zone of a radiatively driven wind. Instead, the absorption arises in material previously ejected from the system. It was only seen on this one occasion because the strength of the emission line had dropped dramatically.

Today, the benefits of open-source (OS) software are clearly established, and many modern software systems build on it. Similarly, the OS movement is also experiencing great advances in areas other than software. This is particularly true in the consumer electronics (CE) domain, where an increasingly growing number of systems are based not only on OS software (OSS), but also on OS hardware (OSH) and OS networking (OSN). This column discusses to what extent it is possible to develop fully OS CE, now or in the near future. The main past and present contributions of OSH and OSN and their relationship with OSS initiatives are reviewed, and the main challenges and opportunities opened up in the context of OS CE are discussed.
