Heat transfer between a rotating wall and a bed of granular material is investigated. This has been shown to be the dominant mode of heat transfer in rotary desorbers used to remediate contaminated soils at wall and gas temperatures of approximately 300 C. Three specific areas of this problem are studied. First, a Stefan-type model is used to evaluate the importance of evaporation near the wall on the wall-to-bed heat transfer coefficient. Next, a heat-balance integral method is used to model wall-to-bed heat transfer, including both evaporation within the bed and a thermal contact resistance between the wall and the first layer of particles. The method is evaluated and then compared to an approximate means with which to include the thermal contact resistance. Thirdly, the wall-to-bed heat transfer problem is solved under the condition of a linearly changing wall temperature. This solution is used to evaluate the consequences of the common isothermal wall assumption.


In order to study the dynamic characteristics of the nonlinear system of the maglev train, a vibration model of the two-degree-of-freedom nonlinear suspension system of the maglev train is established in this paper. Based on the linearized model of the suspension control module, the suspension system is controlled by the state feedback method. Compared with the results of the Runge–Kutta method, the accuracy of the settlement results is verified. This paper analyzes the influence of system parameters and feedback control parameters on the system. The results show that the linear stiffness mainly affects the left-right migration of the resonance peak and the difference between the maximum and minimum of the resonance region of the suspension frame; the nonlinear stiffness mainly affects the slope of the resonance region of the car body and the suspension frame; displacement feedback control parameters can reduce the amplitude of the system, velocity feedback control parameters can make the state change of the suspension frame more smoothly, and acceleration feedback control parameters make the car body and the suspension frame have a strong coupling effect. According to the Hurwitz criterion of Hopf bifurcation, this paper deduces the conditions that the control parameters should satisfy when the equilibrium point is stable, and the instability produces periodic vibration under PID control. Through numerical simulation, it is found that the system has complex dynamic behavior, the results show that the system works under some conditions, and there are multiple stable and unstable limit cycles simultaneously. Therefore, the system will appear alternately between multiperiod and chaotic motion, which will affect the stability of the system.

Red cell deformability (RCD), to be held as a criterion of surface hemorheological changes (SHC), must first of all be distinguished from various linked factors usually measured by laboratory methods attempting to approach measurement of RCD: hematocrit, plasma, and leukocytes are such factors. To assess the importance of SHC in the control of RCD one can study the influence of substances interfering with the membrane (glutaraldehyde, albumin, calcium), or study the deformability of red cells devoid of hemoglobin: ghosts. From the clinical point of view, specific noncongenital changes of blood filterability can be demonstrated, in liver disease for instance, and are related to membrane lipid anomalies. It is quite possible, but not yet demonstrated, that such anomalies explain reduced RCD in other diseases (such as peripheral arterial disease and diabetes). It is difficult, in the present state of knowledge, to link drug action on RCD to their action on SHC, whether they be active or not on calcium movements .


The preparation and characterisation of a series of hydrogen bonded liquid crystalline dimers containing benzoic acid, alkanoic acid and phenol donors and alkoxy-stilbazole or alkoxy-4-pyridone hydrogen bond acceptors are reported. These heterodimers possess strong intermolecular donor–acceptor hydrogen bonding. The heterodimers, as well some of the individual components used in their preparation, possess liquid crystalline phases.


This research aims to explore the human resource management (HRM) practices and their impact on the performance of micro, small, medium enterprises (MSMEs) in the foodservice industry in Jakarta, Indonesia. This topic is crucial to be explored since one of Indonesia's most competitive MSMEs industries is the food and beverage sector. During the pandemic Covid-19, it is to be one of the most important sectors aiding the economy. Meanwhile, the application of HRM practices is often being ignored by MSMEs in Indonesia. This research applied an exploratory, qualitative-based study, using an inductive confirmatory approach. The data were gathered face-to-face and internet-mediated in-depth semi-structured interviews with 12 business owners and managers. The transcripts were then thematically analyzed. The outcome of this research reveals that nine out of ten HRM practices components have impacts on the performance of the MSMEs in the foodservice sector. The ten HRM practices components include human resource planning, recruiting and selection process, orientation, training and development, human resource administration, performance appraisals, wage and compensation, occupational health and safety, disciplinary action, work termination, and career development. Each HRM practices component differs in significance yet serves specific purposes for the MSME and would help the businesses to function better. © 2023 Author(s).


Traditional improved MUSIC algorithm decomposes the signal covariance matrix to make the signals subspace be orthogonal to the noise subspace, so decreases the effect of the noise. But when the signals interval are very small, traditional improved MUSIC algorithm has been unable to distinguish the signals as the SNR decreases. To this problem, a modified MUSIC is proposed which makes full use of signals subspace and its eigenvalue, on basis of the signals subspace obtained be orthogonal to the noise subspace, construct spectrum search function and then estimate the signals. Through computer simulation, it has been approved that when the signals interval are very small under the condition of the lower SNR and exist the correlated signals, modified MUSIC can estimate the sig- nals accurately that traditional improved MUSIC algorithm can't estimate.

The first light signal propagates from the first light source through a waveguide that may also serve as a substrate, wherein the signal that actuates the component of the engine can be the first light signal or a signal generated after the first light signal is produced. The component or subsystem of the engine may be an ignition system or a fuel injection system.


Over the last 40 years the Black Sea recorded a serious degradation of the aquatic ecosystem, mainly due to human pollution. Excessive nutrients concentration in water mass (from agriculture or sewage treatment) caused the apparition of eutrophication in Black Sea. Eutrophication disturbs the aquatic ecosystems and become a risk to organisms that depend on water resource and also to human health. The occurrence of eutrophication phenomenon in the Black Sea produces big economic losses in tourism and fishing industry. This study investigates, based on experimental observations, the causes and effects of eutrophication occurrence. Furthermore, based on current state of eutrophication indicators in the sea water, this paper tried to identify possible methods of rehabilitation of the marine ecosystem.

For some time scholars have examined unconventional linguistic patterns in E. E. Cummings' poetic style. Of all the aspects under consideration, it is grammar, lexis and morphology that have been most widely researched, while only a small number of studies have looked at graphology or, least of all, punctuation. This article is a contribution to the latter research field, and is aimed at developing a systematic approach to the use of punctuation marks in E. E. Cummings' experimental poetry. I deal with two fundamental research questions: What foregrounding patterns are present in E. E. Cummings' unorthodox use of punctuation marks, and what effects derive from his singular use of marks? Using 157 experimental poems as a corpus, I identify any instances of unconventional punctuation and classify the different devices that break with convention, determining the meaning implications (if any) that derive from these particular uses. An in-depth analysis of these poems reveals that there are three basic unconventional devices in Cummings' use of punctuation marks (substitution, omission and insertion) and that these help Cummings to achieve a variety of purposes: emphasize certain elements within the poem, shift the tempo of the lines, create chaotic scenes, produce iconic effects, schematize any unit within the poem, omit letters and words, signal heteroglossia, indicate imperative voice, articulate the poem into different layers, create plays on words, and reproduce features of spoken language.


The Eddic formulas of curse against a perjurer have been compared to Eddic and Russian formulas of oath, mainly showing that the oath is a conditional self-curse. They may be compared to Sanskrit ones which indicate that the curse of oaths formulas correspond to the social function of the perjurer


The extent of condensate flooding as a function of condensate flow rate is measured on six horizontal pin-fin tubes (varying in circumferential pin-spacing) via simulated experimentation. Surface tension to density ratio is tested using three fluids namely water, ethylene glycol and R-141b. Results show that flooding was strongly effected by changing the condensate flow rate. An increase in flow rate caused a marginal decrease in flooding angle (an angle extracted from top of the test tube to the fully flooded flank). Similarly, circumferential pin-spacing also effected the retention angle and the effect goes on increasing by decreasing the surface tension to density ratio.


Edge preserving smoothing of seismic data can be approached using anisotropic diffusion. One approach to this uses a spectral decomposition of the structure tensor to define a diffusion tensor. The resulting partial differential equation is solved numerically. We approach the problem by a structural decomposition of the isotropic diffusion equation itself by separating the Laplacian into directional (parallel- and perpendicular-to-structure) components. Retaining only the parallel term gives a convection-diffusion equation suitable for use in edge preserving filtering of seismic data.


Objective To explore the clinical value of compound pepsin combined Bacillus subtilis II joint viables in prevention of infant secondary diarrhea following bronchial pneumonia. Methods Two hundred and sixty infants with bronchial pneumonia were randomly divided into two groups with 130 cases in each group. Both groups were treated with cefoperazone sodium intravenous injection and ambroxol hydrochloride inhalation. The control group was given oral compound of pepsin powder and the observation group was added with Bacillus subtilis II combined live bacteria pellet orally. The incidence rate of secondary diarrhea,hospital stay time and diarrhea subsiding time were observed and compared. Results Secondary diarrhea incidence rate in 1-year-old,1 to 2- year old and over 2-year-old children in observation group were lower than that of the control group( P 0. 05); but general secondary diarrhea rate was lower( P 0. 01) and diarrhea subsiding time and hospitalization time were shorter than that of those in control group( P 0. 01 or P 0. 05). Conclusion Compound pepsin combined Bacillus subtilis II combined live bacteria oral therapy can reduce secondary diarrhea incidence rate in children with infant bronchial pneumonia and shorten the course of treatment,which is clinically worthy.

The conglutination technology can not only be applied to repair the broken parts of armored equipment, but also play a very important role in wartime recovery and repair.


In the aftermath of the nineties the Dutch government took a cautious step towards private finance of transport (PFI). Demonstrating economic and financial value added of PFI compared with other ways of project implementation was given much emphasis, revealing economic rationality rather than ideology as a basis of PFI policy. The paper provides an analysis of the first results of the PFI route for roads in the Netherlands. The authors have been involved as financial advisors to the Government for both the A59 and the N31 projects. They provide an economic analysis focusing not only on efficiency but equally on quality of service. The design, build, finance and maintain (DBFM) concept introduces private finance of roads as opposed to the longstanding practice of public finance. For the Netherlands, this is an entirely new way of looking at the road infrastructure sector and road management. It is suggested that only limited efficiency gains are actually made from DBFM. These gains can be measured by the Public Sector Comparator, a financial and economic benchmark for private bids on PFI contracts. An operator must strike a balance between (partially) closing the road for maintenance and thus losing on availability and the cost of maintenance. For efficient maintenance contracting may be at the expense of road availability. The A59 and N31 project show that this results in a new organization of road maintenance and renewal. Putting a value on road availability also presents a new element in the Dutch budgetary process. For the covering abstract see ITRD E126595.


A B ST R A C T In this study chloroform and methanol extracts of Ziziphus xylopyrus stem barks were tested for analgesic (Hot plate, Tail immersion and Acetic acid- induced writhing method) and anti-inflammatory activity (paw edema induced by carrageenan) in mice and rats, respectively. The methanolic extract in doses of 50, 100 and 200 mg/kg showed 10.91, 34.95 and 57.61 percentage of protection from writhing respectively and the percentage inhibition of paw edema at the end of four hours was 1.26, 24.05 and 35.42 respectively. In the Hot plate and Tail immersion models, methanolic extract in the above doses increased the pain threshold significantly after 30 min, 1, 2 and 3h of administration. Methanolic extract showed dose-dependent action in all the experimental models in different doses whereas chloroform extract was not able to show such remarkable significant activities.


The Han dynasty fell because the concept of dynastic change had made its way from the people to influential circles in Ts'ao Ts'ao's entourage. Weak emperors, or eunuchs, empresses, and the Yellow Turbans are blamed for the decline of Han, but until a thousand years after its fall efforts were still being made to restore the dynasty. For some, the creation of the Wei dynasty remained an unlawful act which tainted those emperors and their successors with illegitimacy. Liu Yuan had a detailed knowledge of the vicissitudes of Later Han history and the events accompanying its fall. In AD 338, a new Han dynasty was proclaimed in the same city that had served as Liu Pei's capital, in the southwestern corner of China. When the Chinese dynasties were driven to the southeast after 316 by non-Chinese invaders from the north, it was important for them to know that they were the true holders and inheritors of the mandate.


The utility model provides an external wall cleaning device which comprises a rack and a cleaner installed on the rack, and further comprises a cleaning distance adjusting device, wherein the cleaning distance adjusting device comprises a measuring unit used for detecting and outputting a distance signal between the cleaning device and the working surface of an external wall, a controlling unit used for outputting a driving signal according to the distance signal, and a driving mechanism used for driving the rack to make corresponding motion according to the polarity of the driving signal. The cleaning distance adjusting device can adjust the distance between the cleaning device and the working surface of the external wall at any moment, thereby avoiding the defects of idle running, missing cleaning or insufficient scrubbing force due to poor contact between the cleaning brush and the working surface of the external wall, further being capable of cleaning the external wall (especially for the external wall with uneven surface) completely and cleanly, and improving the operating efficiency. The utility model also provides an external wall cleaning robot including the external wall cleaning device.


Al2O3-TiO2 systems with Ti:Al 0.1, 0.5 and 1.0 molar ratio obtained by the sol–gel method have been used as a platinum support. As a precursor of alumina gel, aluminum isopropoxide has been chosen. Titanium tert-butoxylate was applied to obtain titania gel and hexachloroplatinic acid was applied as a source of platinum. The systems have been characterized by the following methods: thermogravimetric analysis (TGA), Fourier transformation infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), low-temperature nitrogen adsorption–desorption isotherms (BET, BJH), temperature-programmed reduction with hydrogen (TPR-H2) and hydrogen chemisorption. Reactions of toluene to methylcyclohexane and selective o-chloronitrobenzene (o-CNB) to o-chloroaniline (o-CAN) hydrogenation were used as the tests of systems' catalytic activity. The application of Al2O3-TiO2 as a support has enabled the obtaining of platinum catalysts showing high activities for hydrogenation of toluene and selective hydrogenation of o-chloronitrobenzene to o-chloroaniline in the liquid phase. The highest activity in both reactions has been found for Pt/Al2O3-0.5TiO2 catalyst and the highest selectivity for Pt/Al2O3-. The activity of Pt/Al2O3-TiO2 catalysts was higher than that of alumina-supported ones.

What happens when a child is kidnapped from home by his or her own parent? What are the emotional and psychological consequences of living in hiding for weeks, months, or even years for a child? How does the parent left behind cope with having no knowledge of the child's whereabouts or well-being? And what could lead a parent to inflict such a painful existence on his or her own child? This text provides a look at the problem of the abduction of children by their parents, portraying the experiences of both the parents searching for their children, and the abductors who have taken them. The reader is given depictions of life on the run and learn, how children who have been in hiding for months and sometimes years cope with moving from town to town and from school to school, and how reunion with the searching parent affects them. Greif and Hegar set the stage for policy change by identifying five common scenarios that end in abduction, and point out how changes in custody and divorce law could help to eliminate, or to more quickly resolve, abduction of children. Geoffrey Greif has also written "The Daddy Track and the Single Father" and "Single Fathers".

Objective: The present study aims to assess the pattern of orthopedic trauma injuries in patients admitted to the Orthopedic Department at Khalifa Gul Nawaz Teaching Hospital in Bannu. Methods: This retrospective cross-sectional study was conducted at the Orthopedic & Traumatology Department of K.G.N. Hospital, KPK, from January 2016 to December 2016. Data were extracted from hospital records of 380 patients admitted for emergency orthopedic surgery due to fractures, lacerations, or both. While the patients with severe head injuries, requiring emergency neurosurgery, immediate abdominal surgery, presenting with a history of bone fractures prior to the present trauma, shifted to the intensive care unit (ICU), or expired in the emergency, were kept under exclusion criteria. The etiologies and frequencies of various orthopedic injuries as per the diagnoses were recorded using a structured questionnaire designed for the study purpose. The ethical review board of Bannu Medical College approved the study protocol. The collected data were statistically analyzed using Statistical Package for Social Sciences (SPSS) version 18.0. Qualitative data was presented using frequency and percentages while quantitative as mean and standard deviation. Results: Out of the 380 cases admitted during the study, most were males (76.0%). Furthermore, these orthopedic trauma injuries were more common in individuals aged 21 to 50 years (66.8%) than in the other age groups. Road Traffic Accidents (RTAs) were the major etiological factor (49.2%), followed by falls from height (31.8%). Upper limb fractures were diagnosed in 46.2% of patients, and 53.6% had lower limb fractures. Isolated radius (14.4%) and femoral fractures (23.9%) were the most frequent diagnosis. Conclusion: The present study provides a brief overview of the major etiologies and diagnoses for orthopedic emergencies. It is essential to identify the risk factors and strategize a prevention plan that should be the priority of the healthcare system to avoid morbidities and mortalities associated with orthopedic traumas.

Two iminocarboranyl germylenes 1,2-[C(tBu)=N(Dipp)Ge(Cl)]-1,2-C2B10H10 (2) (Dipp = 2,6-iPr2C6H3) and [1-{C(tBu)=N(Dipp)}-o-C2B10H10]2Ge (3) have been prepared and structurally characterized. The reaction of 2 with Me3NO or S8 afforded the germanium oxygen- or sulfur-bridged dimer [1-{C(tBu)=N(Dipp)-1,2-C2B10H10}Ge(μ-O)(Cl)]2 (4) or [1-{C(tBu)=N(Dipp)-1,2-C2B10H10}Ge(μ-S)(Cl)]2 (5) containing a Ge2O2 or Ge2S2 four-membered ring, respectively. On the other hand, the reaction of 2 with K[CpFe(CO)2] led to the isolation of an iron-germylene compound featuring a Ge-Fe σ bond, 1,2-{C(tBu)=N(Dipp)Ge[Fe(Cp)(CO)2]}-1,2-C2B10H10 (6). All new compounds were characterized by multiple NMR techniques and single-crystal X-ray analyses.


Colonial and postcolonial discourse studies have almost solely been focusing on Angloand Francophone texts. This thesis mainly deals with colonial and postcolonial discourses from Japan, which has the experiences since the mid nineteenth century both of Western cultural and economic colonisation and occupation on the one hand and of its own colonial (military, political, economic, and cultural) expansion to Asian/Pacific areas on the other. The thesis concentrates on representations of the Pacific, in which Asia/Pacific, Japan, and the West have been involved with one another, the three subjects conditioning Japanese colonialism and postcolonialism. A key argument of the thesis is that the three-way interactions of colonial/postcolonial representations of Japanese in the Pacific region produce a 'colonial subject' different from Eurocentric colonial models and more complex than dominant Self-Other theories have allowed. In considering colonialism and postcolonialism in the Pacific, the thesis points out that the 'Japanese' subject as coloniser/colonised is used in contemporary texts from Japan and Pacific islands to intervene not only in colonial myths of 'southern earthly paradise' but also anti-colonial binarism of oppressor/oppresse d.


Pyopneumothorax following kerosene aspiration is not rare in children, but seldom requires surgical intervention.

It would be impossible, in the time and space available, to cover all of the noteworthy advances that have been made in biochemical genetics during the past year. We have, therefore, selected for review a number of topics that are especially active at the moment and that promise to yield important new results in the near future. At the same time, we have tried to avoid duplicating the material of other chapters in this volume ~vhich are germane to biochemical genetics. We refer, in particular, to the chapters on Metabolism of Nucleic Acids (Macromolecular D NA and RNA) ; Nucleic Acids and Protein Biosynthesis; The Basic Proteins of Cell Nuclei; and Chemistry of Differentiation in Lower Organisms. The reader should consult these reviews, as well as the present one, for a fuller view of current activities in this field. By way of introduction, we should like to call attention to some papers of general interest. The formation of animal viruses in bacterial cells infected with viral DNA has been reported from two laboratories. Abel & Trautner (1) first showed that DNA prepared from vacclnla virus is capable of infecting Bacillus sublilis and giving rise to complete virus particles. This result was confirmed by Bayreuther & Romig (2), who found that DNA from polyoma virus also infects B. subtilis, with the production of complete virus. Since, in both cases, formation of virus particles involves the synthesis of serologically specific coat proteins, these results constitute compelling evidence for universality of the genetic code. A curious sidelight to these findings has been the rediscovery of a series of papers published in the 'thirties by Silber and co-workers in Moscow, in which the growth of pox, herpes, and other animal viruses in yeast and bacteria was described [see (3, 4) and subsequent papers in the same journal]3 A fundamental advance has been made simultaneously by Yanofsky et al. (5), working with the A protein of E. coli tryptophan synthetase, and by Sarabhai et al. (6), with the head protein of bacteriophage T4D. Both groups of workers proved colinearity of the gene with its cognate protein. Roberts (7) has studied an unusual series of mutants in Aspergillus. The genes control utilization of sorbitol and are unusual in that they show complementation in trans-heterozygous diploids but not in heterocaryons. The 1 The literature survey for this review was completed in October 1964. ~ We are indebted to Dr. K. E. Bayreuther for these references.


ABSTRACT Subsequent to the fourteenth century, when the plague passed that gate of quarantine between infected districts and the civilized nations, the world began to think. Physicians and chemists turned their attention to causes of disease, and from the advanced knowledge obtained boards of health were developed. It was found that pecuniary loss from sickness and pestilence was so great that steps were taken to guard against the spread of contagious disease, and the laws of the land in regard to public health have gradually and surely developed into a system which has been successful in warding off these diseases and preventing serious epidemics. This was the first tree, tender and young, which, planted in the gloom and despair of a plague-stricken people, bears fruit today, ''for the healing of the nations."Our health laws and ordinances, pestilences and plagues have been great reformers. Old Pharaoh was no believer in bacteriology.

The question of whether the oxygenation pattern of the B-ring of flavonoids is determined at the cinnamic acid stage or at the stage of a C15-intermediate remains to be solved. 3.4.2′.4′.6′Penta-hydroxychalcone-2′-glucoside-[β-14C] (I) was synthesized and the incorporation of I and of 4.2′.4′.6′ Tetra-hydroxychalcone-2′ glucoside-[β14C] (II) into quercetin and cyanidin in buckwheat seedlings was compared in parallel experiments. The percentage incorporation of II into quercetin was about 35 per cent higher than that of I, whereas the incorporation rates and dilution values of both chalcones into cyanidin were about equal. These findings are discussed in the light of earlier results. It is concluded that in the case of asters, buckwheat and red cabbage the 3′-hydroxyl group in ring B is in all probability not introduced until after the formation of a chalcone intermediate. These results are compared with those obtained by other workers with different plants.

The conditions for zero re(cid:29)ectance of weakly absorbing multilayer structures as well as those for the maximal re(cid:29)ectance of transparent structures with an absorbing substrate have been determined. For the instrumentality of these conditions used for transparent multilayer structures two di(cid:27)erent methods of the designing of the narrow bandpass (cid:28)lters with one or more bandpasses have been proposed. The obtained methods can also be used for designing (cid:28)lters with ultra-narrow bandpasses. One of these methods provides a more narrow bandpass at the use of the same total number of layers, but in the second method smaller values of shape factors are reached. The possibility of designing (cid:28)lters with an arbitrary position of the narrow bandpass within the rejection band is shown.


Since Michelle Fine's writing on the missing discourse of desire in sex education, there has been considerable prompting among sexuality educators and feminist scholars to incorporate talk of pleasure into sex education curricula. While the calls for inclusion continue, few have actually examined the curricula for a pleasure discourse or explored how it is contextualised within sex education curricula. In this paper, we analysed curricula used in the USA in the past decade. A qualitative thematic analysis revealed that the discourse around pleasurable sex was often linked to a range of dangerous or negative outcomes including not using condoms, rushing into sex without thinking, regretted sex, and pregnancy or STDs. When the discourse around pleasure was included in sections on 'knowing one's body', this discourse took a medicalised, scientific tone. Pleasurable sex was also presented in more positive ways, either linked to marriage in Abstinence Only Until Marriage curricula, or within a more feminist discourse about female pleasure in comprehensive sex education curricula. Our research indicates that a discourse of desire is not missing, but that this discourse was often situated as part of a discourse on safe practice and there, continues to equate pleasure with danger.


Sharpe's efficient frontier or "capital market line" which is based on Markowitz's nonlinear efficient frontier consists of all different combinations of risky assets and is based on several assumptions, which displays the preference of this frontier to Markowitz's mean-variance efficient frontier (Busser, 1977; Merton, 1972). Although, this theory is effective for investing companies which holds unlimited amount of resources and huge amount of funds, it does not have any application for individuals who do not tend to borrow or lend and are willing to invest in limited number of shares. The most underlying purpose of this article is to present a mathematical model and to demonstrate the methods of investment in limited number of shares in a way that the unsystematic risk which the market does not reward is minimized.


Purpose : Positron Emission Tomography (PET) imaging offers the possibility of measuring brain metabolic activity in vivo. However, brain PET images remain difficult to interpret in clinical setting because of the limited spatial resolution of current generation clinical PET scanners. Therefore, the resulting partial volume effect (PVE) is a challenging issue for brain PET image interpretation and quantitative analysis. To overcome this limitation, several algorithms allowing the correction for PVE (PVC) have been developed and assessed mainly in research setting. In this work, we perform a comparative study of 5 different PVC methods using clinical studies. Methods : 17 clinical studies of patients suffering from neurodegenerative disease were included in our study protocol. 3D T1-weighted MRI and FDG-PET were acquired on dedicated MR and PET-CT systems, respectively. MR images were rigidly co-registered to corresponding PET images using the Hermes multimodality platform and segmented using statistical parametric mapping package (SPM8). The resulting images were corrected for PVE using four voxel-based techniques proposed by different groups including Alfano, Muller- Gartner, Meltzer, and Shidahara, and one volume of interest (VOI)-based technique proposed by Rousset. Results : Our results demonstrate a significant increase of the activity concentration in the gray matter. Consequently, the activity in the white matter decreases considerably when using all PVC methods, except for Meltzer and Shidahara. The comparative analysis demonstrates that, among all considered techniques, Alfano's method appears to substantially increase the GM signal. When applying the different PVC methods to specific regions of interest linked to a specific pathology, the results highlight the bias when using uncorrected PET images, but still respecting specific modification patterns of the disease. Conclusion : Our results confirm the necessity of applying PVC to brain PET images in order to obtain more reliable and accurate quantification. This applies particularly to elderly patients with neurodegenerative disease where atrophy induces underestimation of the true PET signal.


Citrus is one type of fruit that is highly favored by the people. Citrus plants are vulnerable to pests and plant diseases that intensive use of pesticides in the field can not be avoided. Citrus fruits commonly consumed in the form of raw materials that need to be considered food quality and safety of citrus fruits to public health. This study aims to identify and analyze pesticide residues in citrus fruits in the district of Dau, Malang (a case study in the Village Tegalwaru subdistrict Dau, Malang) as one of the centers of citrus production in East Java with the use of pesticides are quite diverse. This research is a survey and observational with cross sectional approach. Data use of pesticides by farmers was measured by a survey conducted for the farmers and merchants. The sample was 3 kg of oranges produced by three farmers and 3 kg of oranges produced by 3 merchants Village Tegalwaru District of Dau, Malang where interviews illustrate the differences in the type and frequency of the use of pesticides during the growing season oranges, which is a high level (sample A ), medium (sample B) and low (sample C).

The corrosion of c e r a m ic oxides by molten uranium and its alloys was examined. Dense, high-purity alumina, m a g nesia, zirconia, beryllia and thoria were studied. The studies included: (a) wettability of c e r a m i c s; (b) products of reaction; (c) mechanism of reaction; (d) contamination of molten u r a nium by crucible material; and (2) the effect of alloying additions on these.


The experiments here recorded were made with the object of confirming in a distant land and with patients of another race our earlier studies 1 on the isolation and cultivation of the leprosy bacillus. A description was given of a slow growing non-chromogenic acid-fast organism isolated from human leprous tissue by incubating the inoculated media in an atmosphere of 40% O2 and 10% CO2. There was unequivocal evidence of the proliferation of the germs but it was also true that the quantity was limited. The organisms were removed from the positive tubes and transferred to freshly prepared sterile media; after an incubation period of about 6 weeks the tiny colonies that had developed were subcultured as before. A total of 26 serial subcultures were made but there was no apparent improvement on the part of the cells to assume a saprophytic existence. The culture in the 26th generation showed the same characteristics as at the beginning of the series. A subsequent communication 2 reported efforts to provide a more suitable substratum. Several of the complex formulae ordinarily employed for the isolation of such species as Johne's bacillus and the tubercle bacillus were prepared and inoculated; in addition amino acids and fresh vegetable tissues were incorporated in several of the usual laboratory media. The results were uniformly disappointing. The overwhelming numbers of organisms in the lesions of the disease and the impoverished growth in test tubes led to the conclusion that some essential food factor was lacking in the nutritive media. There have been several criticisms directed at the studies carried out in Puerto Rico; the most important of which has been the suggestion, that in making the serial subcultures, tissue debris containing stainable organisms was mechanically transferred from tube to tube, leading to the erroneous conclusion that proliferation had occurred when actually no in vitro multiplication had taken place. The appearance of definite colonies, although of limited size, gave assurance that such was not the case, however in planning the protocols for the studies in the Philippines adequate controls were included to obviate this as well as other objections.


A descriptive study was undertaken to identify the self-care deficits related to personal care of the admitted patients in selected wards of Nehru Hospital, PGIMER, Chandigarh. The self-care deficits were described with respect to various self-care activities including feeding , bathing, dressing and toileting. Subjects were interviewed and observed by using patient's profile sheet, general assessment proforma and self care deficit assessment scale. A total of 650 subjects were included in the study. It was found that mild, moderate and severe deficits for feeding was in 20.77%, 6.46%, 7.85%; for bathing in 24.6%,14.6%, 5.5%; in case of dressing it was present in 18.21 %, 12.65%, 5.86% of the subjects and for toileting it was in 9.22%, 15.53% and 7.12% of the subjects respectively. In total it was found that 56.08% of the subjects were able to perform their self-care activities, whereas 19.61 %, 14.75% and 9.56% had mild, moderate and severe deficits respectively in carrying out their self-care activities

Spraying trials have been conducted in southern California over a period of three years concerning control of the grape bud mite, a physiological strain of the grape erineum mite–Eriophyes vitis– (Pgst.). During this period approximately 55 acres of plots have failed to provide information concerning the prevention by spraying of the injury caused by this mite. This is because of the erratic nature of the appearance of bud mite symptoms.


Pre‐release dietary treatment with methoprene, a juvenile hormone analogue, decreases the age at which male Queensland fruit flies mature and hence may decrease the post‐release delay until released sterile flies participate in sterile insect technique (SIT) programmes. However, if matings of young methoprene‐treated males are not effective at inducing sexual inhibition in their mates, then this treatment may not enhance SIT. The present study investigates efficacy of matings of methoprene‐treated males at inducing sexual inhibition in their mates. Methoprene incorporated into a diet of sugar and yeast hydrolysate (w/w 3:1) for 48 hr after emergence resulted in significantly increased male mating propensity when flies were <10 days of age, but not when older, and longer copulations. Copula latency did not vary with methoprene treatment but did decrease with age. The matings of young methoprene‐treated males were effective at inducing sexual inhibition in their mates, matching the efficacy of untreated mature males. Regardless of treatment, females had reduced tendency to remate if their first mate was 15 days of age than if their first mate was younger (6, 8 days) or older (20, 25, 30 days). Females mated by methoprene‐treated males that did remate tended to remate later in the day than females mated by untreated males. Also, second copula durations of females first mated by a 6‐ to 10‐day‐old male were shorter if the male was methoprene treated. These patterns in remating females may indicate greater efficacy of the initial mating of methoprene‐treated males. Overall, we find that the additional matings of young methoprene‐treated male Queensland fruit flies are effective at inducing sexual inhibition in their mates. This finding supports the incorporation of methoprene into pre‐release diet for SIT.


The study was progressed with the purpose of using it as a basic data for more various and developed plan of Townhouse through the research of several instances of characteristics of Townhouse, a type of residence.

So its outside space forms a group of a green tract. Facilities show four types such as a independent type, the sunken type, a underground type, and a under deck type.


We define a specific class of zero-sum stochastic games with signals which are a generalization of the "Big-Match" game of Blackwell and Ferguson. We show the existence of the max min.


Offshore wind farms provide benefits over onshore farms in terms of the amount of generated energy and environmental impact. Cost efficient energy transmission is one of the challenges of those installations. In this context direct connection of parallel connected DC wind turbines to the transmission line is a promising solution. Modular DC-DC converters are an attractive solution for the direct connection of the DC wind turbines to the transmission line. In addition, the phase-shifted full-bridge converter (PSFB) is a good candidate to form simple, efficient and reliable high voltage modular DC-DC converters for offshore DC networks. This paper proposes a novel energy conversion scheme for the direct connection of the DC wind turbines to the transmission line. Design criteria for the phase-shifted full-bridge converter and the medium frequency transformer are described and a modular energy conversion scheme is sized to operate with 10MW offshore wind turbines and 300kV transmission voltage.


The experiment material is embryo of Cymbidium torliseplumin in hybrid seeds in suit when symbiotic germination breaks through the coat of seed.Orthogonal experimental design was used to observe the effect of sodium hypochlorite concentration,sterilization time,sterilization times and ultrasonic treatment time on the control of fungi pollution and embryo culture.The results showed that the ratio of embryos contaminated by fungi was 16.0%,with the lowest embryo survival rate of 14.3%.The ratio of sodium hypochlorite concentration∶sterilization time∶sterilization times∶ultrasonic treatment time(4%∶15 min∶1 times∶6 min).Obviously,it could not suit the sterilization condition of the embryo culture.Furthermore,we noticed that the contribution on the embryo survival rate ordered by decreasing was sodium hypochlorite concentration,sterilization times,ultrasonic treatment time,and sterilization time.The embryo survival rate was 93.3%,and the contamination rate was just 19.0%.The concentration of sodium hypochlorite∶sterilization time∶ sterilization times∶ultrasonic treatment time(=1%∶20 min∶2 times∶3 min).It demonstrated that this matching can be used to cultivate the Cymbidium torliseplum embryo,and under this condition,embryo can absorb nutrients from the culture medium,and develop into rhizome.


The phase noise (PHN) is one of the primary factors that limits the achievable performance in many communication systems. Recently, the authors have proposed an effective "2-paths" PHN compensation scheme (L. Zhao et al, Globecom 2003). The approach uses the information provided by an additional signal path added to the receiver front-end to better estimate the PHN. There are generally two types of PHN found in the literature: stationary PHN and Wiener PHN. Previous results have shown the effectiveness of the "2-paths" scheme for stationary PHN. This paper addresses the applicability of the "2-paths" scheme for combating Wiener PHN. It shows that simple modifications of the "2-paths" approach work effectively for Wiener PHN as well. PHN estimation error and signal-to-noise ratio (SNR) after PHN compensation are analyzed. Simulation results for a 64-QAM system demonstrate the significant improvement over conventional approaches in the presence of Wiener PHN.

At the beginning of the 1990s, due to the abolition of the socialist economic structure, the Central and Eastem European Countries (CEECs) were suddenly forced to thoroughly transfonn their political and economic order. This drastic situation is unique in history. With the transfonnation process , high expectations arose regarding policy, economy, and science. Due to the dissolution of the Yugoslavian Federation, Slovenian finns had to find new markets, and Slovenian research institutes had to alter their research priorities and intensify their contacts with industry (WalterlBross 1997). Already in fonner Yugoslavia, Slovenia was the most industrialised region, which achieved 29 % of the total of Yugoslavian exports with only 8 % of the total population in 1990 (European Commission 1993: 5). Even after its independence in 1991,1 the small country has remained primarily export-oriented with approximately 20 % of higher-priced technology products (phannaceutical products , goods from the e1ectronic and electrical engineering industry), approximately 50 % mid-tech and about 20 % low-tech products. Due to the process of economic adaptation, a drop in production was noted in a1l branches. Economic collapse especially threatened tradition al industrial sectors such as steel and heavy machine construction, the automobile industry, and the textile and furniture sector. Although the transition of the industrial sector is not yet complete, the number of business enterprises has obviously grown during the past years, especially in the areas of small enterprises and the service sector.

Ralph Woollett spent most of his life studying the subject of electroacoustics. He approached the subject with the attitude of a physicist, trying always to understand and to relate what he knew to basic physical laws. But he was also an engineer, analyzing the behavior of new transducer designs and creating new design concepts such as trilaminar flexural transducers and magnetostrictive drive of flexural bars. It was the good fortune of his colleagues that he also devoted much of his time to teaching them his way of looking at electroacoustics and suggesting interesting and relevant problems for them to work on. He was active in ASA and IEEE committees and was a U.S. delegate to the International Electrotechnical Commission's Subcommittee on Ultrasonics. Ralph's untimely, accidental death reminded us of a lesser known side of his personality, for he was an avid flyer and somewhat of an adventurer who was always seeking new experiences and challenges.


The formation of a dust filter cake was simulated by a computer program. Thereby a maximum of three different layers in the dust cake was found, but the actual number of layers was dependent on the compressibility of the cake. For the description of the compression behaviour of the cake the friction angle φ and the maximum adhesion force Z max were introduced. The goal of our investigations was to find out which types and sizes of the three layers could be expected in dust filter cakes with different compressibility.


Indian Remote Sensing Satellite (IRS) LISS-II and III images of different years/seasons (1988-2001) were used to compare the water-covered areas and the water hyacinth-covered areas of six water bodies (Doddabommasandra, Yelahanka, Jakkur, Rachenahalli, Nagavara and Hebbal) in and around the northern parts of Bangalore city, Karnataka, India, giving the exact areas under hyacinth cover. The findings showed that the area under water-hyacinth cover has increased in recent times compared with previous years. One possible reason for this is the pollutants being let into the water body, having excess nutrients which are absorbed by water hyacinth thus increasing the area under cover. The growth of water hyacinth is directly related to the nutrients like phosphates, nitrates, etc. which are mainly from agricultural runoff, sewage and industrial effluents. This would give an idea of the human activity in the catchment of the water body. The water area has thus reduced/decreased during the years, which has led to considerable depletion of its levels. The area of water body is mapped using satellite data and compared with actual area as indicated by the map of 1974. Recent field studies showed pollution levels to be generally high with ammonical nitrogen, alkalinity, increase in biochemical oxygen demand, chemical oxygen demand, sodium, iron, calcium, and total solids favouring robust growth of water hyacinth. These parameters are important for understanding the issues of management of freshwater resources. Monitoring the temporal changes in water hyacinth would be useful to understand the dynamics of a weed and its ecology as the 'most successful colonizer'.


&dquo;What is now proved was once only imagined.&dquo; Curiously, virtually nothing about elementary statistics is proved in the text. To many students, the bare facts about statistics will seem metaphysical when robbed of their mathematical beginnings. When the student is given only the fruits of the statistician's labors and never watches him at work, those products must seem strange indeed. One can imagine a student asking of statistics presented without mathematics,


Current methods for conducting exact inference for logistic regression are not capable of handling large data sets due to memory constraints caused by storing large networks. We provide and implement an algorithm which is capable of conducting (approximate) exact inference for large data sets. Various application fields, such as genetic epidemiology, in which logistic regression models are fit to larger data sets that are sparse or unbalanced may benefit from this work. We illustrate our method by applying it to a diabetes data set which could not be analyzed using existing methods implemented in software packages such as LogXact and SAS. We include a listing of our code along with documented instructions and examples of all user methods. The code will be submitted to the Comprehensive R Archive Network as a freely-available R package after further testing.


A self-steered robust Capon beamformer is proposed to address the problem of significant performance degradation caused by the large look direction error. The basic idea behind the proposed method is to reconstruct the interference-plus-noise covariance (INC) matrix precisely. First, the noise covariance matrix is estimated by the eigen-decomposition. Then, the interference covariance matrix is obtained by integrating the signal power outside the region-of-interest (ROI) using the maximum entropy power spectrum (MEPS) estimator. Simulation results show that the proposed beamformer's main beam can be self-steered to the real direction-of-arrival (DOA) of the signal, thus can effectively suppress the large look direction error and achieve the performance close to the theoretical optimal value.


OBJECTIVE To further investigate the alkaloids of the roots of Delphinium omeiense W. T. Wang. METHODS Silica gel chromatography was adopted.RESULTS Eight known C 19 -norditerpenoid alkaloids were obtained, their structures were established as cardiopetalidine 1, ajacine 2, browniine 3, delcaroline 4, 6-demethyldelphatine 5, takaosamine 6, omeieline 7 and indaconitine 8 on the basis of spectral data.

The study examined association between selected socio-demographic characteristics of traders and hypertension. A descriptive cross-sectional design was adopted in this study. The study population consisted of adult traders in the Ibadan metropolis, Nigeria. The sample consisted of 596 respondents from the three major tribes in six major markets in Ibadan metropolis. The sample for the study was selected using multi-stage sampling procedure. Demographic variables measures were taken using an inventory to determine respondent age, sex, marital status, ethnicity, religion, number of children and number of years in business while weighing scale and measuring tape for height was were used to measure weight and height and sphygmomanometer was used to determine their hypertension status. The frequency distribution of socio-demographic characteristics of the respondents was tabulated while chi-square analysis was used to test the hypothesis at 0.05 level of significance. The findings of this study revealed that the socio-demographic characteristics related with hypertension are age, marital status, number of children, number of years in business, body mass index while sex and ethnicity were not related with hypertension. It was recommended that those at higher risk of hypertension should be adequately educated on what and what not to do. There is also an urgent need to educate traders to know their health status and to monitor their blood pressure regularly for early detection of hypertension and prompt treatment given.


Abstract Self-excitation of the motion of a structure has become a prominent aspect of engineering projects over recent years as designers are using materials at their limits, causing structures to become progressively lighter, more flexible and, therefore, prone to vibrate. Stimulated by the increasing interest in fluid–structure interaction (FSI) problems, this study investigated the instability and consequent FSI-induced self-excited oscillation of flexible structures in uniform flows at Reynolds numbers between $10$ and $1. 69\times 1{0}^{5} $. The investigations were performed in both water and a highly viscous syrup ($\nu = 1. 64\times 1{0}^{- 4} ~{\mathrm{m} }^{2} ~{\mathrm{s} }^{- 1} $) and considered three structures of different geometries. The results were conclusive in showing that the motion of the structure was characterized by a sequence of oscillation modes as a function of the characteristics of the structure and flow properties. In addition, it was possible to identify the self-excitation mechanisms as being of the instability-induced excitation (IIE) or movement-induced excitation (MIE) types. IIE was observed to be the most dominant mechanism of excitation at lower velocities and it was defined by a direct relation between the flow fluctuation and natural frequencies of the structure. For that reason, IIE was strongly determined by the geometry of the front body of the structure. At higher velocities, the amplitudes of the flow disturbances generated by the structure movement increased and excitations of the MIE type became predominant for all structures. The MIE mechanism was found to be weakly influenced by the shape of the structure but very sensitive to its dynamic characteristics and to the properties of the fluid, especially the Reynolds number.

In the past 50 years, the tetracycline antibiotics has played an important role in the treatment of infectious diseases. However, a large amount of tetracycline in human and veterinary medicine has led to many organisms previously susceptible to tetracycline antibiotic resistant. The modular synthetic tetracyclines and tetracycline analogues can be various tetracycline analogs and previously obtained by the difficult synthetic and semisynthetic tetracycline early multi prostacyclin (polycyclines) to provide an effective path to selectively enantiomer. These analogs in the treatment of human or other animal diseases useful as an antimicrobial agent or an antiproliferative agent.


The inability of incoming students to advance past the traditional first-year calculus sequence is a primary cause of attrition in engineering programs across the country. As a result, this paper will summarize an NSF funded initiative at Wright State University to redefine the way engineering mathematics is taught, with the goal of increasing student retention, motivation and success in engineering. The approach involves the development of EGR 101 a first-year engineering course replacing traditional math prerequisites for core sophomore engineering courses along with a more just-in-time structuring of the required calculus sequence. Since its inception in Fall of 2004, the impact of the Wright State model on student retention, motivation and success has been widely reported. This paper includes results of a recent longitudinal study of program impacts at Wright State University, from student performance in math and engineering to ultimate graduation rates. Results show that the program has substantially mitigated the effect of incoming math preparation on student success in engineering across the entire range of incoming ACT math scores, which has more than doubled the average graduation rate of enrolled students. Moreover, it has done so without watering down the caliber of graduates, who have actually enjoyed a slight (but statistically significant) increase in graduation GPA. Finally, the approach has been shown to have the greatest impact on members of underrepresented groups, for many of whom the traditional engineering curriculum is simply not accessible. The paper concludes with a longitudinal examination of student perception data, which appears to establish a clear link between program impacts on student motivation and self-efficacy and ultimate graduate rates. The Wright State Model It is well known that student success in engineering is highly dependent on student success in math, and perhaps more importantly, on the ability to connect the math to the engineering. However, first-year students typically arrive at the university with virtually no understanding of how their pre-college math background relates to their chosen degree programs, let alone their future careers. And despite the national call to increase the number of graduates in engineering and other STEM disciplines , the inability of incoming students to successfully advance past the traditional freshman calculus sequence remains a primary cause of attrition in engineering programs across the country. As such, there is a drastic need for a proven model which eliminates the first-year mathematics bottleneck in the traditional engineering curriculum, yet can be readily adopted by engineering programs across the country. Such is the focus of this work. The Wright State model begins with the development of a novel first-year engineering math course, EGR 101 Introductory Mathematics for Engineering Applications. Taught by engineering faculty, the course includes lecture, laboratory and recitation components. Using an application-oriented, hands-on approach, the course addresses only the salient math topics actually used in core engineering courses. These include the traditional physics, engineering mechanics, electric circuits and computer programming sequences. The EGR 101 course replaces traditional math prerequisite requirements for the above core courses, so that students P ge 2.76.2 can advance in the curriculum without first completing a traditional first-year calculus sequence. The Wright State model concludes with a more just-in-time structuring of the required math sequence, in concert with college and ABET requirements. The result has shifted the traditional emphasis on math prerequisite requirements to an emphasis on engineering motivation for math. The EGR 101 lecture sections are completely driven by problem-based learning, while the laboratory and recitation sections offer extensive collaborative learning among the students. As such, the course is strongly supported by the literature on how students learn. Excerpts from the EGR 101 laboratory are shown in Figures 1-2. Indeed, physical measurement of the derivative as the velocity in free-fall (Fig. 1), or of the integral as the area under the force-deflection curve (Fig. 2), provides a much greater conceptual understanding of the mathematical concepts than classroom lecture alone. The Wright State model was first implemented in Fall of 2004, and its effect on student retention, motivation and success in engineering has since been widely reported. The 2007 introduction of EGR 199 as a precursor to EGR 101 for initially underprepared students has further strengthened the approach, and has made Wright State's core engineering curriculum accessible even to incoming students with math placement scores as low as 3 levels below Calc I. Results of the initial implementation are briefly summarized below. Results of Initial Implementation The EGR 101 course ran for the first time in the Fall of 2004. All eligible incoming students in mechanical engineering, materials science and engineering, electrical engineering, engineering physics, biomedical engineering and industrial and systems engineering were enrolled in the course. Through its first year of implementation, a total of 158 students were enrolled in EGR 101, with over 74% completing the course with a grade of "C" or better. The initial implementation of the program had an immediate and dramatic effect on student retention and success in engineering at Wright State. As shown in Fig. 3, every department requiring EGR 101 saw an increase in first-year retention in 2004-2005, as compared to baseline data averaged over the prior four years. Overall, majors requiring EGR 101 saw first-year retention increase from 68.0% to 78.3%. Figure 1. The Derivative Lab Figure 2. The Integral Lab


Mixed refrigerant Joule-Thomson (MRJT) cryocoolers can produce cryogenic temperatures with high efficiency and low operating pressures. As compared to the high system pressures of around 150–200 bar with nitrogen, the operational pressures with non-azeotropic mixtures (e.g., nitrogen-hydrocarbons) come down to 10–25 bar. With mixtures, the heat transfer in the recuperative heat exchanger takes place in the two-phase region. The simultaneous boiling and condensation of the cold and hot gas streams lead to higher heat transfer coefficients as compared to single phase heat exchange. The two-phase heat transfer in the recuperative heat exchanger drastically affects the performance of a MRJT cryocooler. In this work, a previously reported numerical model for a simple tube-in-tube heat exchanger is extended to a multi tubes-in-tube heat exchanger with a transient formulation. Additionally, the J-T expansion process is also considered to simulate the cooling process of the heat exchanger from ambient temperature conditions. A tubes-in-tube heat exchanger offers more heat transfer area per unit volume resulting in a compact design. Also, the division of flow in multiple tubes reduces the pressure drop in the heat exchanger. Simulations with different mixtures of nitrogen-hydrocarbons are carried out and the numerical results are compared with the experimental data.


The program of Cultivating Excellent Engineers serves as a role model and guidance for promoting socially needed talents on the high educational level and comprehensively improving the qualities of engineering talents. It is important to rebuild the existing scientific and engineering professional laboratories' equipment. Based on the recent years of cultivating applied-type talents with the help of rebuilding the relevant professional laboratories of Shaoguan University, the paper put forward the road map of the rebuilding and its advancing construction ideals, production and applying methods, equipment and model real-training software, at the same time fully taking advantage of all resources by cooperating with companies building the professional laboratories off-campus which challenged the traditional model.


Through the coupling of turbulence model,multiphase flow model and electromagnetic brake(EMBr) model,the fluid flow and level fluctuation of CSP funnel type mold are simulated in the 1 500 mm×90 mm CSP funnel type mold with the casting speed of 5 m/min.The numerical simulation results indicate that the application of EMBr improves the behaviors of fluid flow in the mold significantly.And the flow field inside the mold is more uniform.The maximum fluctuation height is obviously reduced from 15 mm under the condition of without EMBr to 9.2 mm and 2.33 mm when the magnetic flux density is 0.2 T and 0.3 T,respectively.Considering both the braking effect and the production cost,the magnetic flux density which is between 0.2 T and 0.3 T could be reasonable.

Crystals of the title compound, C13H11N3O3, were obtained from a condensation reaction of salicylaldehyde and 4-nitrophenylhydrazine. The molecule exhibits a planar structure, with the 4-nitro group slightly inclined to the plane. The molecules link to each other via intermolecular hydrogen bonding between the imino and nitro groups.


The spatial, statistical structure of the fluid velocity field in the case of uniformly recharged heterogeneous aquifers is investigated, and the spatial covariances of the velocity field are derived. This information is necesary for an investigation of flow and macrodispersion using the Lagrangian formalism proposed by Dagan (1984). The resulting first two moments of the velocity are nonstationary. They are functions of a parameter β which characterizes the degree of flow nonuniformity and is related to the recharge. The displacement variances are computed and tested favorably using numerical simulations. Simple relations are developed which relate the transport parameters found for the case of uniform-in-the-average flows to nonuniform flows using a simple, nonlinear transformation of the travel time, based on β.


The possibility to monitor the cardio-respiratory activity in a non-invasive way, by measuring thoracic displacement using cost-effective microwave Doppler technology, has been studied. Several laboratory tests were performed in order to demonstrate the feasibility of the proposed electromagnetic measurement method. Time domain signal processing techniques have been used in order to evaluate the main frequency and rate variability of the heartbeat and respiration signals. They have shown a very good correlation coefficient with the electrocardiogram and spirometer results, used as reference instruments. On the other hand, a simple electromagnetic model was developed in order to analyze the scattering problem, using appropriate analytical and numerical techniques.


Remote sensing plays an important role for mapping and monitoring of floods and wetlands. Synthetic aperture radars (SAR) are of special importance due to their ability to penetrate cloud cover and their high sensitivity to the occurrence of surface water and variations in soil moisture. During flood events this sensitivity typically leads to deviations from backscatter behaviour that is observed under non-flooded conditions. These alterations are typically mapped using change detection techniques in which the changes between a preand a post-flood SAR image are quantified and classified. However, a number of open research questions exist with respect to automatic detection of flood-induced backscatter changes: (i) in change detection, selection of a suitable pre-flood reference image is often not trivial. This is especially the case when user intervention should be minimised, a constraint often imposed by the requirements of automatic processing chains. (ii) Numerous studies have demonstrated the importance of seasonality in backscatter from different land-surface types, which is typically not addressed explicitly in change detection methodologies. (iii) A number of confounding factors exist that contribute to the overall uncertainty of the delineated flood extents, such as ambiguous radar signatures of different land-cover types and the contribution of speckle. Traditionally, binary flood maps include no information on the expected uncertainty introduced by these factors whereas more recently, flood mapping methodologies have been proposed that result in fuzzy or probabilistic flood maps. The overall objective of this thesis is to address these open questions by introducing and evaluating a novel change detection framework for mapping flood-induced deviations from long-term backscattering behaviour. For this purpose, backscatter signatures were derived by characterising seasonality using harmonic analysis of ENVISAT Advanced SAR (ASAR) Wide Swath time series spanning multiple years (> 50 scenes). The estimated harmonic model parameters were analysed and discussed for complex wetland areas in the context of ancillary data on hydrological and biophysical processes. The model residuals were used as a measure of the flood-induced deviation from average seasonal backscattering behaviour. Finally, a Bayesian approach was applied for deriving probabilistic flood maps from the residuals. The results show that harmonic analysis of SAR time series can be effectively used for deriving seasonal signatures characteristic of different landsurface types. Moreover, the applicability of the model parameters for classifying different wetland backscattering classes is demonstrated. The use of the model residuals for delineating areas that were inundated during non-seasonal events indicates that seasonal harmonic model estimates can serve as a reliable estimate of the seasonal backscattering behaviour a land surface would display under non-flooded conditions. The probabilistic flood mapping approach is shown to provide reliable maps and can be used for characterising uncertainty caused by some of the aforementioned factors. In conclusion, the proposed approach provides a framework for characterising seasonal backscattering behaviour and detecting flood-induced backscatter changes in SAR time series. An outlook to using the proposed method in the context of novel SAR missions such as Sentinel-1 is provided.


We study the magnetization reversal in rectangular ferromagnetic thin film elements using the magneto-optical Kerr effect for magnetometry and domain observation. The aim of this study is to support the global simulation of magnetic materials such as by the Preisach concept by microscopic investigations. As we are able to study in these samples the whole domain structure as a function of an applied field in real time, we can investigate in detail the question of reproducibility of magnetization processes starting with an identical initial configuration. We observe an obviously intrinsic irreproducibility of the main domain rearrangement process characteristic for these samples. This property of an unpredictable magnetization process can be influenced by a superimposed alternating field.

In this paper, we evaluate three-dimensional (3D) multi-core processors with temperature constraint. 3D multi-core processors are structured by stacked conventional planer dies and high density through silicon vertical wires for die-to-die connections. Thus, 3D multi-core processors have a potential to integrate many number of cores. However, 3D multi-core processor's temperature increases in keeping with stacked dies. For handling the thermal issue, power reduction techniques such as frequency scaling are required. However, this kind of approach negatively impacts on processor performance. From our experimentation, it has been observed that 3D multi-core processors can achieve performance gains at executing high parallelism applications.


The purpose of this study was to examine the experiences of two university graduate students while taking an online course over the World Wide Web, in order to identify issues of design, implementation, and motivation from a user's perspective. The online course was a graduate class on the methods and techniques of training and development. Data collection included descriptions of course content, page design and presentation, assignments and tests, communication techniques, schedule of events, and student/student and instructor/student interactions. Experiences were documented through questionnaires, interview data, and students' annotated experiences during the semester. Issues of course design and delivery, student characteristics, online communications, motivation and self-discipline, and technical problems were examined. Results indicate ways designers designing a Web course, instructors teaching a Web-based course, and students taking a course online can employ instructional strategies to insure the greatest probability of success.

The Bidirectional Associative Memory (BAM) is a type of artificial neural network that was shown to bear great performances in learning and recalling various types of associations. However, this model has always been investigated under optimal conditions in which all the patterns have the same desirability and the network is fully connected. In this paper, the influence of spreading-activation and sparseness in a BAM network is studied. Results show that even under such variability the performances of the BAM are unaffected. This study gives us a better understanding of how attractors can be developed and could lead to more robust computational intelligence systems.


Bisphospholane Josiphos-type ligands were synthesized in high yields employing electrophilic and nucleophilic phospholane synthons. Full characterization data including solid-state structures of the diastereomeric ligands are reported. These ligands resulted in active and enantioselective iridium catalysts for the asymmetric hydrogenation of imines. Pronounced cooperative effects of the chiral elements within the ligand structure were observed and enantioselectivities of up to 74% ee were achieved.


The sources of urban water in the United Arab Emirates are groundwater, desalinated water and treated wastewater. About three-quarters of desalinated water are used for irrigation to amenity plantations. Water consumption in major cities varies between 170 and 200 liter per capita per day (Lpcd) in flats and between 270 and 1760 Lpcd in villas. Irrigation to roadside plants, home gardens and to recreation areas has been increasing in the region with the rapid growth of its urban development. Diversification of water sources and water demand reduction are therefore considered two vital tools for the security of urban water supplies. Currently about 98% of municipal wastewater are centrally collected through an efficient sewerage networks and then treated for reuse to provide irrigation to roadside plantations. The treated wastewater is not conveyed to houses because of the necessity of dual reticulation systems. Reuse of greywater (household wastewater except from kitchen and toilet) for non-potable consumptions (gardening and toilet flush) can be an alternative. The objective of this study is to investigate the potential for decentralized (individual houses) harvesting and reuse of greywater in Al Ain city for non-potable consumptions. An attempt has been undertaken to estimate domestic water consumptions and greywater generation in the city. The frequency and water volume of personal water uses (shower, ablution, toothbrush, hand wash, face wash, toilet flush) and family water uses (laundry, dish wash, home clean, car wash, pet wash, gardening) were estimated from 100 homes randomly distributed across the city. Their probability distributions were fitted using the normal, log-normal, gamma and logistic distributions. The estimated average greywater generation rate was found to be 195 Lpcd. For personal water uses, highest consumption was observed in shower, toilet flush and ablution accordingly. About 70% respondents considered greywater can be reused for gardening. Considering the high variability of water uses frequency and time requirements, the probabilistic model is recommended for greywater quantitative analysis.

S_(2n).


Conference papers explore shifting conceptualizations of love and romance and their expression in contemporary practices of dating and courtship. Recent studies have documented how in many areas of the world, young people are expressing a new interest in romantic love and companionate relationships different from that associated with their parents and grandparents (cf. Hirsch & Wardlowe 2006, Lipsett 2004, Padilla et al 2007, Zigon 2013). This new interest is reflected in a shift in marriage patterns away from conjugal matches arranged by familial elders to matches involving a greater degree of individual choice. These shifts in marriage patterns have been linked to both demographic as well as socio-cultural transformations – among them the shift away from agricultural production toward wage labor; higher education, urbanization, and the growth of a new middle class; the association of new marital practices with ideas of progress; and a focus on individualized achievement and consumption as markers of success (Hirsch & Wardlowe 2006).


The polymerase chain reaction (PCR (1)) can amplify DNA of known sequences up to 1015 fold. Analytically, the amplified DNA's are usua-lly electrophoresed in gels and detected either by staining or by hybridization after blotting. We propose the use of labeled primers in the chain reaction to detect the product rapidly and guantitatively. Methods: Primers, 100 pmol each, were labeled with 12P-ATP (2 ul, 7000 Ci/mmol, ICN) and polynucleotide kinase (5 u, Boehringer) in 10 ul of 50 mM Tris-HCl, pH 8.3, 10 mM MgC12 and 5 mM DTT at 37 degree for 30 min. The PCR mixture (GeneAmp kit, Perkin Elmer Cetus) containing 2.5 ul of the kination mixture and 0.25 ug of a sample DNA in a total volume of 25 ul was made in a 0.5 ml microfuge tube as recommen-ded by the manufacturer. The solution was incubated in a Thermal Cycler (Perkin Elmer Cetus; 94, 55 and 72 degrees for 0.5, 0.5 and 1 min respectively, per cycle). A portion of the product was mixed with 1/4 vol. of a dye solution containing 50 % glycerol and 1 % SDS and applied onto a 5 % polyacrylamide gel in 0.5 x TBE (20 x 40 x 0.03 cm, 1 cm/lane). After electrophoresis for 1 h at 40 W with cooling by the aid of a fan, the gel was dried and contacted to a Kodak XAR film. The procedure (including exposure to the film) ends within 6 h and involves neither restriction enzyme digestion nor hybridization. Relative band intensities among samples in LP-PCR

Controlled atmosphere (CA) during vessel transportation is a standard procedure in shipment of preclimacteric bananas (Musa sp. AAA, cv. 'Grand Nain') from Central America to North America or Europe. The purpose of the CA treatment is to reduce the risk of premature ripening in transit, known commercially as ripe and turning. On arrival at their destination, CA is interrupted and bananas are transported to ripening facilities where they are treated with ethylene. In order to understand the impact of preclimacteric CA storage on ripening speed and post-ripening characteristics of bananas, an experiment was conducted that simulated vessel storage under air or CA conditions, followed by commercial ripening. Green bananas were stored under 3% O 2 or air conditions for 15 days at 14°C and 95% RH in a flow-through system at flow rates of 10 l/h. Ten replicates of 18 kg of bananas per replicate were used per treatment. Respiration rates were measured daily with gas chromatography. To reduce variability among treatments, each hand of a bunch was divided in two, numbered and stored under CA or air. After storage, fruit was ventilated in air for 2 days at 14°C and then exposed to 300 μl/liter ethylene for 24 h at 16°C. Fruit was stored at 16°C after treatment with ethylene. Six postharvest parameters (L, 'a' and 'b' values, firmness, Brix, color by color chart) were evaluated daily after ethylene application. CA-stored fruit had higher firmness and lower Brix values for the first 3 days after ethylene treatment. These differences disappeared as fruit reached commercial 'retail-store' ripeness. No significant differences were found in any of the color parameters.


This Monograph will explore the empirical and theoretical ramifications of journalism as social media, specifically "journalism as process." The piece calls for an end to thinking about news as a discrete product and the beginning of considering news production as a shared, distributed action with multiple authors, shifting institution-audience relationships and altered labor dynamics for everyone involved. Using the exemplar of one Midwestern city - Madison, WI - and its information-production/consumption community, this research stems from a newsroom ethnography and 100 interviews with journalists, bloggers, and members of the socially mediating public. It puts forward the idea that news has become a transportive, transactional object of professional, social and civic work for both journalists and audience members.

Based on the traditional microchannel heat sink, using the heat spreader with high heat conductivity and special microchannel array with variational cross section areas, an entire steady flow model and a short-distance heat transfer model of working fluid was realized. Applying commercial FE software package [ANSYS],the flow velocity distribution and temperature field of the typical heat transfer unit of microchannel heat sink was given with the reference flow rate 1 m/s and the temperature 283 K. The heat flux of 5×10~7W/m~2 can be dissipated and the total thermal resistance is below to 0.0 106℃/W. The simulational result proves the initial design concept and illustrates this microchannel heat sink would have good working performance.


In courses that include a teamwork component, students do most of their collective work outside the purview of the professor. The guts and glory of the team's experiences happen outside of the classroom. Many of those peaks and valleys can be pivotal learning opportunities if they are processed and reflected upon in a safe, facilitated environment. This session will discuss the conditions and strategies that encourage team members to give actionable feedback to each other in order to improve team functioning and performance.
