This study investigates the conditions of occurrence and petrographic characteristics of low‐Mg calcite (LMC) from cold seeps of the Gulf of Mexico at a water depth of 2340 m. Such LMC mineral phases should precipitate in calcite seas rather than today's aragonite sea. The 13C‐depleted carbonates formed as a consequence of anaerobic oxidation of hydrocarbons in shallow subsurface cold seep environments. The occurrence of LMC may result from brine fluid flows. Brines are relatively Ca2+‐enriched and Mg2+‐depleted (Mg/Ca mole ratio <0.7) relative to seawater, where the Mg/Ca mole ratio is ~5, which drives high‐Mg calcite and aragonite precipitation. The dissolution of aragonitic mollusk shells, grains and cements was observed. Aerobic oxidation of hydrocarbons and H2S is the most likely mechanism to explain carbonate dissolution. These findings have important implications for understanding the occurrence of LMC in deep water marine settings and consequently their counterparts in the geological record.


This paper describes a comprehensive experimental and numerical project implemented in a third-year applied thermodynamics course. In the project, students experimentally investigate the performance of a single-cylinder spark ignition (SI) and then develop a numerical model for the same engine which accounts for non-isentropic and finite-duration heat release effects. Using the experimental data and numerical model, students investigate the impact of compression ratio and spark timing on a variety of engine performance parameters such as peak pressure, power, and efficiency.
 The project has some unique learning outcomes. First, students are able to compare the performance of a real SI engine to the Otto cycle model studied in class. Second, they gain experience applying concepts from thermodynamics, heat transfer and numerical methods to develop a realistic numerical model for the actual engine. In the development of the model, the constants needed for closure of the model and system of equations must be obtained empirically from the experimental data. This experience provides students with valuable insight into the inner workings of commercial simulation software packages where closure models are often developed from experimental data.
 The paper concludes with suggestions of additional tasks and refinements that can be incorporated into this project to capture real-world effects such as heat losses during the combustion process. In addition, challenges in the implementation of this project and hurdles encountered by students are also discussed along with some suggestions to counter these issues.


Todays ICs usually employ one bandgap voltage reference (BGVR) circuit to generate a well defined voltage that is reused at many places in that IC. The classical BGVR generates a reference voltage that is slightly larger than the material bandgap: a little above 1200mV in silicon. For deep-sub-micron technologies the supply voltage is about the same as the material bandgap which prevents using the classical bandgap structure. As a solution a number of BGVR topologies that create a sub-1V are invented; most of them are based on the structure introduced by Banba [1], some are using resistive voltage division [2] or voltage averaging [3]. For low-power operation high-ohmic resistors (occupying a large area!) must be used in all these techniques, leading to an immediate trade-off between power consumption and chip-area. This trade-off prevents the local generation of reference voltages where they are required: either the power penalty or the area penalty would be too significant. Alternative topologies that do not require high-ohmic resistors typically are not-BGVR-based circuits relying on threshold voltages and hence require trimming to achieve low spread.


A superconducting RF accelerator test facility is currently under construction at Fermilab. The accelerator will consist of an electron gun, 40 MeV injector, beam acceleration section consisting of 3 TTF-type or ILC-type cryomodules, and multiple downstream beam lines for testing diagnostics and performing beam experiments. With 3 cryomodules installed this facility will initially be capable of generating an 810 MeV electron beam with ILC beam intensity. The facility can accommodate up to 6 cryomodules for a total beam energy of 1.5 GeV. This facility will be used to test SRF cryomodules under high intensity beam conditions, RF power equipment, instrumentation, and LLRF and controls systems for future SRF accelerators such as the ILC and Project-X. This paper describes the current status and overall plans for this facility.


| 1 On October 29, 2015, China scrapped its one-child policy, allowing all couples to have two children for the first time since strict family planning rules were introduced more than three decades ago. Despite the optimistic responses of some demographers and citizens on Chinese state media, the shift to the new two-child policy may disappoint those who expect the policy to lead to balanced population development and mitigation of China's rapidly aging population.


Personnel directors (N=34) responded to a mailed adjective checklist describing the-ideal secretary. This list contained eight adjectives cxorresponding to each of Holland's sixvocationally-related personality traits (Realistic, Social, Investigative, Enterprising, Conventional, and Artistic) and eight feminine and eight masculine adjectives from the Bela Sex Role Inventory. The results revealed that the personnel directors preferred a Holland profile high in the Conventional and Social areas and low in the Artistic area (p .001), but had also'selected more masculine than feminine items (p .01). The most frequently checked adjedtives were pradtical, tactful, friendly, confident, self-controlled, efficient, stable, orderly, detailed, helpful, responsible, energetic, self-reliant, conscientious, cheerful, cooperative, precise, and honest. The least frequently checked adjectives were shy, introverted, impracticali cumlicated, popular, compassionate, risk-taker, emotional, non-conforming, pleasure-seeking, -sympathetic, liumbie, materialistic, cautious, domineering, obedient, gentle, adventurous, convincing, and disorderly.

Brink, Ph.D., M.B.A., Director Graduate Program in Public Administration College of Notre Dame Belmont, CA 94002 Personnel directors (N = 34) responded to a mailed adjective checklist describing the ideal secretary. The list contained eight adjectives corresponding to each of John Holland's six vocationally-related personality traits (R,I,A,S,E,C), and eight "feminine" and eight "masculine" adjectives from Bem. Results indicated that the personnel directors preferred a Hie C high S low A Holland profile (p ( .001), but had also selected more masculine than feminine items (p ( .01). An analysis of the individual items'helped to explain the latter finding. INTRODUCTION: Holland's (1965) hexagonal model of vocationally related personality traits contends that office positions, be high on the C factor. For the past half century, the position of secretary has been associated with women, and the term "pink collar workers" has come to describe dead-end clerical jobs with no upward mobility. Therefore, the two hypotheses guiding this research were that 1) The ideal secretary would be described in terms associated with a *high C Holland code. 2) The ideal secretary would be described in terms v4 O C) CD METHOD: associated with feminity. In thespring of 1987, a hundred personnel directors of electronics firms headquartered in Silicon Valley received a mail in survey, comprised of a 56 item adjective checklist: eight adjectives related to each of Holland's six factors, and six were "masculine," six were "feminine" items from the BSRI (Bem, 1974). (Two masculine and two feminine items were counted doubly, as representing both a given Holland trait as well as masculinityfemininity.

INFORMATION CENTER (ERIC)." 2 BE,ST. 'COPY ,AVAltAig ;1 FIESULTS: Thirty-four returns were received within the next three months. The average personnel director had.circled 43% of the available adjectives. The most frequently checked adjectives were practical, tactful, friendly, confident, self-controlled, efficient, stable, orderly, detailed, helpful, responsible, energetic, self-reliant, conscientious, cheerful, cooperative, precise, and honezt. The least frequently checked adjectives were shy, .introverted, impractical, complicated, popular, compassionate, risk-taker, emotional, non-conforming, pleasure-seeking, sympathetic, humble, materialistic, cautious, domineering, obedient (!?!), gentle, adventurous, convincing, and disorderly. The mean number of adjectives circled for each Holland code: R = 3.15 S = 5.15 I 2.91 A = 0.97 E = 2.56 C = 5.71 These data were statistically significant, according to Friedman's rank test for repeated measures (chi square = 108.60, df = 5, p ( .001), thus confirming Holland's claim that secretarial work requires a high C, high S personality. Surprisingly, the average numbef of "feminine" adjectives checked was only 1.79, while the average number of "masculine" items checked was 2.94. (Friedman's rank test for repeated measures yielded a chi square of 7.53, df = 1, p ( .01). This unexpected finding becomes comprehensible upon an item analysis. While almost all the personnel directors did circle the "feminine" trait cheerful, only half circled the "feminine" trait of understanding,.and viritually no one circled gentle, sympathetic, compassionate, or shy. Regarding the "masculine" traits: the majority of the respondents circled self-reliant, about half circled ambitious, independent, assertive, and analytical, and virtually no one circled risk-taker. DISCUSSION & CONCLUSION: It must be kept in mind that the personnel directors responded to a hypothetical or theoretical situation, in which they were called to describe the "ideal" secretary, and this approach may not yield thesame results as a concurrent or predictive validation using real secretaries as the subjects, or an experiment about whether or rot personnel directors really do tend to hire obedient job applicants for secretaries. Let us hope that the advance of office technology and humanistic theories of management bring about a trend in industry to want a more selfreliant, autonomous employee in secretarial positions, so that the plight of the pink collars may become history. I HOLLAND'S VOCATIONAL TRAIT MODEL interpreted by T.L. Brink, Ph.D., M.B.A. In order to understand Holland's theory, imagine a six-sided box. each of the six corners there is a given personality trait that is vocationally linked. In each person, some of these traits will be more pronounced than others, predisposing that individual to be more compatible with certain occupations instead of others. CONVENTIONAL (C) people like to carry out details and follow through on instructions. These folk enjoy order, certainty, security. They make good accountants, office workers, civil servants, and military. They can put up with an assembly line. Most large organizations have a hard time assimilating people who do not have at least a moderate C trait. ARTISTIC (A) people can be found in the corner 180 degrees away from the C people described above. A great source of confusion comes when we confuse the ARTISTIC personality with artistic ability or even artistic interests. A person with artistic ability can paint, sculpt, sing, tapdance, or write. A person with artistic interest may enjoy tapdancing, or going to an art gallery, or listening to music on the radio. A person who is high on the ARTISTIC personality factor is someone who would be best working in the loose, unstructured atmosphere in which creativity thrives. Now, notice, not every tapdancing, stained glass enthusiast who likes to play Bach on the stereo necessarily has this A personality factor. Not all high A jobs involve the fine or performing arts. Writers, broadcasters, philosophers, advertisers, and professors necessarily work in high A environments. So do commercial artists, musicians, actors, directors, photogra9hers, architects; fashion models, and designers.


A microscopic model is employed to relate the dielectric tensor to the microstructure of isotropic amorphous or cubic crystalline materials. Electrostriction is characterized by dielectric parameters that describe how the dielectric tensor varies with deformation and the resulting change in the microstructure. These dielectric parameters are obtained for small deformations, and expressed in terms of measurable, macroscopic properties. Unlike previous approaches, we avoid employing the Lorentz cavity approximation to determine the local polarization. Dipole sums are renormalized by treating the dielectric constant of the undeformed material as a known quantity. Predictions agree with our experimental data for different block copolymer films. Further progress in understanding electrostriction and developing improved models requires measuring the deformation dependence of the dielectric tensor for various materials under various conditions (field strength and frequency, deformation frequency, temperature, etc.).


Objective
To compare the infectivity of several transformed Chlamydia trachomatis (Ct) mouse pneumonitis (Mopn) strains to host cells, and to identify cell invasion-related virulence genes in Chlamydial plasmids.

Methods
Several Ct strains, including wild-type Ct Mopn strain (WT strain), plasmid-free Ct strain (CMUT3 strain), Ct Mopn strain transformed with the shuttle vector carrying pGFP and the complete C. muridarum (CM) plasmid (pGFP::CM strain) and Ct Mopn strains transformed with shuttle vectors carrying pGFP and mutant CM plasmids with in-frame deletions of Pgp3, 4, 5 or 7(pGFP::CM△Pgp3, 4, 5, 7 strains), were cultured, amplified and collected. After the concentrations of Ct were determined, each of these strains was divided into four groups to be inoculated at a same amount (1.5×104 inclusion forming units (IFU)) followed by four different treatments respectively: centrifugalization+DEAE group treated with centrifugalization followed by ion-exchange chromatography on diethylaminoethyl (DEAE)-cellulose columns, centrifugalization group treated with centrifugalization only, DEAE group treated with chromatography on DEAE-cellulose columns only, control group receiving no treatment. After additional culture for 20-24 hours, indirect immunofluorescence assay was performed to count the number of chlamydial inclusions. At 20, 40 and 60 hours after infection, the growth rate and area of chlamydial plaques were assessed after three continuous passages. Lugol′ s iodine staining was conducted to observe glycogen synthesis in bacterial inclusions.

Results
The inclusion number in the centrifugalization+DEAE group, centrifugalization group, DEAE group and control group was 10.20±1.30, 6.80±0.44, 3.00±1.22 and 0.80±0.45 respectively for the pGFP::CM△Pgp4 strain, 6.40±0.89, 3.80±0.83, 1.60±0.89 and 0.60±0.54 respectively for the CMUT3 strain. Under same experiment conditions, the pGFP:: CM△Pgp4 strain and CMUT3 strain showed similar infectivity, and formed less inclusions compared with the other Ct strains (all P<0.01). The number of inclusions formed by the same Ct strains were significantly different among the 4 groups (F=845.310, P<0.01), and were highest in the centrifugalization+DEAE group for all the strains. The pGFP:: CM △Pgp4 strain showed significantly lower growth rate and area of plaques with an abnormality in glycogen accumulation compared with the other strains at 20, 40 and 60 hours after infection.

Conclusion
The plasmid-encoding gene Pgp4 may be a cell invasion-associated virulence gene in chlamydial plasmids.

The gas flow field distribution and the molar fraction distribution of oil gas in the RFCC disengager after anti-coke deposition retrofitting were simulated by using k-e model and species transport equation. Results indicated that the oil gas flow field was not symmetrical and the lengthways velocity was 10 or 102 times larger than the transverse velocity. Gas in the upper space of the disengager flowed downwards with the velocity less than 0.15 m/s and the upward stream existed in the lower part with the velocity about 0.5 m/s. Near the center of the disengager gas pooled towards the nozzle of plenum tube with its velocity of 10 m/s. There were no stagnant regions for gas current and most of it was pumped out of the disengager quickly except for a small portion,which only took 10% mass fraction of all the oil gas with some what longer residence time correspondingly. The average molar fraction of oil gas was 50% at the bottom of the disengager and less than 25% in the upper place,even less than 10% in some areas. Total coke deposition in the disengager was reduced after anti-coke amelioration.


The E&P sector can learn much about asset maintenance from the space and satellite industry. Practitioners from both the upstream oil and gas industry and the space and satellite sector have repeatedly noted several striking similarities between the two industries over the years, which have in turn resulted in many direct comparisons in the media and industry press. The similarities between the two industries have even resulted in a modest amount of cross-pollinating between the respective supply chains. Because the operating conditions of both industries are so extreme, some oil and gas equipment vendors have occasionally sourced motors and other parts from aerospace contractors. Also, satellites are now being used to assess oil fires, detect subsidence in oil fields, measure oil spills, collect and transmit operational data from oil and gas fields, and monitor the movement of icebergs that might potentially collide with offshore oil and gas installations.


On the basis of a study of earthquakes pattern, transmision and register modeling, we have written a software package capable to generate synthetic seismograms in a half space from four canonic sourees capables to simulate a large quantity of focal mechanisms.


Many business and policy for cutting down the building energy consumption are being implemented to achieve the energy or CO2 reduction target in our country. To accomplish CO2 reduction target in building industry, many strategies have been implemented. Finally, the government aim to develop the net-zero energy building. In this study, as an case study for net-zero energy building, a small-sized post office building was tried. In this paper, the strategies to accomplish the net-zero energy building will be described and the annual energy demand (including energy generation by P/V cell) will be discussed.


At high tide the beautiful upper Tamar River, in the heart of Launceston, is a fitting gateway to the iconic Cataract Gorge. However, beneath the turbid waters lurk issues of sewage effluent and excessive silting. Blame has been cast on upstream municipalities in the Esk River catchments, forestry practices, an outdated sewage system and other local factors. Consensus on how best to proceed seems as remote as any time over the past 200 years. Now, a better understanding of how the estuary works gives new hope that consensus and a sustainable solution are achievable.


Infusible, insoluble black powderlike poly(acenequinones) whose macromolecules are composed of condensed aromatic rings linked by quinoid fragments were synthesized by the melt cyclopolycondensation of pyromellitic dianhydride with pyrene in the presence of zinc chloride. The ladder structure of these polymers and the layer packing of amorphous structure elements were established by X-ray diffraction, scanning electron microscopy, and IR and ESR spectroscopy. For the synthesized poly(acenequinones), the parameters of dielectric spectra were determined. The region of dispersion of a complex dielectric constant was shown to be due to the interlayer polarization of conducting domains. The produced polymers showed high thermal stability (900°C), electric conductivity of the order of 10 -7 -10 -3 S/cm, and paramagnetism (narrow ESR singlets corresponding to concentrations of the paramagnetic centers equal to 10 19 -10 20 spin/g).


Two cases of malignant lymphoma with skin and secondary central nervous system (CNS) involvement were reported.Case 1: A 69-year-old male presented with the skin, paranasal cavity, laryngeal and intrathoracic involvement by B cell lympboma (diffuse medium cell type). He also complained of paraesthesia on the left leg. Although these lesions almost disappeared after VEPA therapy, the patient complained of clounding of conciousness and poor memory two months later. Examination revealed leptomeningeal involvement and epidural spinal cord compression. Lumbar puncture disclosed numerous atypical cells which were positive for CD20. The patient died of pneumonia after few months, although these atypical cells in the spinal fluid disappeared after intrathecal chemo-therapy.Case 2: A 61-year-old male developed cutaneous T cell lymphoma (diffuse medium cell type) without any other symptoms. The skin lesions disappeared after VEPA therapy. He suddenly developed clouding of conciousness and poor memory after one year of remission. CT scans showed an intracerebral mass. In spite of whole brain irradiation and both systemic and intrathecal chemotherapy, the tumor did not decrease in size and the patient died of pneumonia after 1.5 years.In the literature, CNS involvement developed 5-10% of adult malignant lymphoma. The risk factors for secondary CNS involvement were considered to be stage IV diseases, B symptoms, diffuse large cell or mixed cell type, involvement of the testis, peripheral blood, nasal/paranasal sinuses and bone marrow. Thus, the case 1 might have been given a prophylactic treatment, since he had several signs described above.


Hyperferroelectrics are receiving a growing interest thanks to their unique property to retain a spontaneous polarization even in presence of a depolarizing field. Nevertheless, general microscopic mechanisms driving hyperferroelectricity, which is ascribed to the softening of a polar $LO$ mode, are still missing. Here, by means of phonons calculations and force constants analysis in two class of hyperferroelectrics, the ABO$_3$-LiNbO3-type systems and the prototypical hexagonal-ABC systems, we unveiled common features in the dynamical properties of a hyperferroelectric behind such $LO$ instability: negative or vanishing on-site force constant associated to the cation driving the $LO$ polar distortion, and destabilizing cation-anion interactions, both induced by short-range forces. We also predict possible enhancement of the hyperferroelectric properties by applying an external positive pressure; pressure strengthens the destabilizing short-range interactions. Particularly, the increase in the mode effective charges associated to the unstable $LO$ mode under pressure suggests an eventual enhancement of the $D$=0 polarization under compressive strain.


Three pagan narratives underlie the Book of Esther. These basic narratives were merged into one story, which expressed the problems of Jewish life in the diaspora. In an attempt to adjust Palestinian Judaism to the Jewish diaspora, the theme of Purim was introduced into the narrative.


The problems of multilevel preparation of the specialists on computer directions and organizations of such preparation at the Kharkov technical university were considered.

Transition-metal-incorporated ZrO2 gel matrices have been prepared by an impregnation method. The polymorphic forms of the studied gels at room temperature were determined by Fourier-transform IR (FTIR) spectroscopy and X-ray diffraction (XRD) techniques, and the phase transformation behaviour of the gels was investigated with using differential thermal analysis (DTA) methods. For both undoped and doped ZrO2 gels, DTA reveals metastable tetragonal–monoclinic–tetragonal–cubic phase transformations in the heating process up to 1400 °C. A high-temperature tetragonal–monoclinic transition is also observed in the cooling process. For the metal-loaded ZrO2 gels, it is found that the diffusing metal cations stabilize the low-temperature tetragonal phase. However, for high-temperature (900 °C) calcined gels, both as-prepared and metal-stabilized tetragonal phases are reduced substantially. Correlations between metal diffusion and gel polymorphic stabilities are also demonstrated.


Objective   It has been reported that both normal pituitary and pituitary tumours express PPAR‐γ, a nuclear hormone receptor, the expression being more abundant in pituitary tumours, and that this is the basis for the reported antiproliferative effects of the thiazolidinedione, rosiglitazone, in animal models. However, the mechanisms for the responsivity to rosiglitazone have remained unclear.


The local stress concentration of the main girder during the tensioning construction of the continuous box girder bridge strengthened by the cable-stayed system is more prominent, which may lead to the sudden damage of the structure. Therefore, this paper studies the key section stress and deformation of the main girder in combination with the real bridge test. The results show that the maximum tensile and compressive stress increase of the main girder appears at the root floor and midspan floor; The tensile action strengthens the compressive stress between the anchorage point of the long cable and the anchorage point of the short cable to the top of the pier, which releases some of the compressive stress across the mid-slab, improves the stress state of the main girder, and improves the shear load of the main girder ability; With the increase of the cable force, the main tensile stress of the web in the anchoring area first increases and then decreases. The lifting amount of the midspan section of the main girder accounts for 20.06% of the total deflection, and the effect of the cable-stayed system on improving the deflection of the main girder is obvious.


to predict pregnancies with FGR by whole-genome sequencing of cell-free fetal DNA (cffDNA). Methods: We collected 210 maternal serum samples from two groups of pregnant participants: healthy controls and pregnant women with FGR for WES. We calculated the RPKM value of the gene promoter coverage to indicate differentially expressed genes between two groups. Logistic regression models were used to clearify FGR from controls. Results: In the study, gene promoter coverage of 17 genes were found to be differentially expressed between 42 pregnancies with FGR and 168 healthy controls, by the DNA-sequencing analysis (figure 1a). We construct a FGR classifier (FGRC) based on 13 gene (HPS5, PTDSS2, OR4P4, PNRC2, CD63, VPS35, VAV1, DNPEP, TCF7, DPP6, LANCL2, GPAT4, FAM214B) combination with the logistical regression model, achieved high performance (AUC > 0.7 and accuracy > 79%) in 1st, 2nd and 3rd trimester to distinguish between FGR and controls. AUCs for the prediction of FGR when using the FGRC are given in table 1 and figure 1b. Conclusions: cffDNA may therefore be a promising noninvasive test to identify pregnancies at risk of developing FGR at term, although they require validation in larger, blinded clinical trials.


How is digitalisation being implemented in schools? The crucial factor in this respect is the work of system administrators, who play a decisive role in its shaping and realisation as the driving forces behind it. While their interface function provides system administrators unique know-how and expert knowledge, they are, at the same time, structurally limited in their scope of action. This constellation ultimately affects the quality of the implementation of digitalisation in schools. In this study, digitalisation researcher and sociologist Stephan Graßmann analyses the everyday work of system administrators and provides important insights into and ideas on improving digitalisation processes in schools.

Research documents the benefits of experiential exercises in business courses. The experiential exercise is a teaching method that allows students to be engaged in the learning process. Experiential learning is widely recognized as an effective way for students to learn about essential business management topics. Just to name a few, experiential exercises are employed in understanding such topics as social responsibility and ethics, team effectiveness, decision making, organizational and international culture, emotional intelligence, and conflict management. The key to experiential exercises is that if provides an opportunity to understand management in a manner that shifts the student from a passive to an active participant in the learning process. However, the experiential exercise can be both fulfilling and terrifying for the professor. This paper offers practical guidelines to assist professors in the implementation of experiential exercises in management classes.


The full vectorial numerical analysis of finite non-planar hybrid structure reveals that both highly confined bound surface plasmon modes and leaky surface plasmon modes are supported in such structure. The extremely low effective mode area associated with highly confined mode makes the waveguide a hotspot source and the tunable antenna mode which is a subdivision of leaky mode is useful for both beam steering devices and free space coupling. The dispersion propertiy, propagation length, and the confinement factor of these plasmon modes have been analyzed and presented in this study.


Department of Condensed Matter Physics, The Weizmann Institute of Science, Rehovot 76100, Israel(June 26, 2011)We calculated the Coulomb drag contribution to the resistivity and the transresistivity for adouble layer system, in which the passive layer is a Wigner crystal pinned by impurities, and theactive one is a metal. We found that in quasi one dimensional systems both quantities are suppressedat low temperatures by the constraints of energy and momentum conservation in electron-phononscattering. In two dimensions both quantities are ∝ T


The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to convert them into zero discharging industries by recycling the wastewater. The sludge can be used for producing bricks when it is in the slurry phase thus eliminating the need for water for producing bricks and the need for sludge disposal.

A possible mechanism that the self-fields effect of the relativistic electron beam plays a dominant role in the power enhancement of a 35 GHz/61 MW free-electron laser with a reversed guide magnetic field is proposed. Qualitative explanation is that the self-fields felt by the electrons are different when the axial guide magnetic field is reversed from positive to negative, which changes the electrons' motion and results in different energy exchange between the electron beam and the wave.


Due to Venturi flow meters' low cost,structural simplicity,reliability and installing facility,they are widely used in single-phase flow measurements.After having been experimentally studied and theoretically studied for many years,they are considered,among all traditional differential flow-meters,to be most appropriate for measuring gas-solid two-phase flows.By making use of a two-phase flow model,the two phase flow in Venturi tubes has been numerically simulated,the flow pattern of the gas phase and that of the solid phase,as well as their interaction,analyzed,and the accuracy of the model verified.Figs 7,table 1 and refs 8.


and in the ways we plan our lessons so that differentiation helps even more students succeed, particularly those struggling with literacy. To do that, an equally intuitive framework for differentiation is in order; one that does not require extensive training or preparation but still creates a classroom infrastructure within which differentiation occurs. Whether we approach DI from the point of view of differences in readiness, differences in ability, differences in interest, or differences in learning profile, it involves multiple or differentiated resources, a variety of instructional strategies, and a range of options for demonstrations of understanding. Carol Tomlinson (1999) discusses differentiated content, process, and product. This could be interpreted as differentiated curriculum, instruction, and assessment. In other words, we can differentiate the resources we use, the ways we ask students Figure 1 to interact with the content, TO and the ways we ask students The foundation to demonstrate their learning. I have been a classroom Direct instruction teacher for over 30 years, at Main lesson every level from grades one My project presenta through twelve, and in multiple disciplines. If there is one thing Teacher-focused I have learned, it is that I have Introduction of skill to make that conscious and Teach intentional effort to differentiate on a daily basis. Whether we are I do talking about using multiple resources, different instructional strategies, or more performance-based assessments, I try always to be conscious of the unique group of students with whom I am working. And I intentionally plan my lessons to not only target state and district standards but also the readiness, abilities, interests, and learning profiles of the students in that classroom (Campbell, 2009). The basic formula I have used for many years is To-With-By: I teach something to my students, this is usually in the form of direct instruction; then I work with my students, this is essentially guided instruction; then I push them to work more independently or by themselves, this is self-directed learning. Such an approach is sometimes referred to as Teach-Practice-Apply or I doWe do-You do. Regardless of the moniker, the beauty of this approach to teaching is that the teacher can use differentiated strategies at all three stages. Moreover, it is scaffolded for all students to ensure a "gradual release of responsibility" (Bruner, 1983). In otherwords, the process itself is differentiated in that it works through three tiers or levels that challenge students at progressively higher levels, plus the learning strategies within each tier are also differentiated.

Users expect that systems react instantly. This is specifically the case for user-centric workflows in business process-driven environments. In today's enterprise systems most actions executed by a user have to be checked against the system's access control policy and require a call to the access control component. Hence, improving the performance of access control decisions will improve the overall performance experienced by the end user significantly. In this paper we propose a caching strategy which pre-computes caching entries by exploiting the fact that the executions of business processes are based on the execution of actions in a predefined order. We propose an accompanying architecture and present the results of our conducted benchmark.


The piping system is a tool for distributing fluid from one equipment to another equipment. PT Jakarta Tank Terminal (JTT) which operates in product storage services has many piping systems that are used to distribute Mogas from storage tanks to tank cars. JTT will develop 2B phase that is the construction of TK0305 storage tank and the piping system to 33LP0001 pump suction header pipe along 162 m in the tank farm area 3 with flowing mogas to the truck loading bay using a capacity of 750m 3 /h. The piping system must be designed safely in accordance with the operating conditions referring to ASME B31.3 so the leakage and excessive costs in the construction of the piping system can be avoided. From the analysis, the nominal diameter of the pipe is 14 in. The selected pipe material is ASTM A53 Grade B. The selected pipe wall thickness is 0.375 in (SCH 30 ST) which accommodates a corrosion allowance of 0.0591 in. The maximum support distance is 13,526 m which is safe relating to the pipe deflection and stress. In the design of the piping system, the flexibility with the planned parameters and pipelines has been fulfilled. The stress analysis of the piping system was carried out utilizing the Caesar II with sustain, expansion, operational and hydrotest loading.


The theory and application of present finite element method have misconceptions. These misconceptions include the insufficient understanding of functional space of finite element and the formulation of weak form derivatives. These misconceptions block the development of finite element method, which lead to the difficulty and failure in solving some problems. The theory and application of quasi-conforming finite element method are displayed as a reference. A sequence of functions is defined to demonstrate the functional space of finite element. The independence principle of elements is given to solve the "conforming problem". The polynomial basis rather than "shape function" is emphasized. The formulation of approach functions of finite element is discussed, which should convergence to the corresponding Taylor series. It is proved that the weak form of strain-displacement equation is necessary and sufficient condition of weak form of equilibrium equation. The string net weak derivative is proposed, which expands the connotation of weak form derivative in finite element method.


Bolivia is a country of great mineral wealth with known reserves estimated to be worth over US$7 billion. Despite this great potential wealth, in the early 1980s the mining industry of Bolivia found itself in a crisis characterized by excessive state intervention in the industry, a financially troubled state mining company, large areas of the country off-limits to mineral development, an irrational tax system which discouraged mining and labour unrest. To deal with these problems, the government decided to restructure the mining industry so as to encourage private participation. This paper describes the policies introduced to revitalize the mining industry as well as projections of what the future benefits would be to the country if those policies are successful in achieving their objectives.


Training is an important approach to human resource development. More and more enterprises realize the importance of training, "investing in training" has become the focus of many large corporate investment. A questionnaire survey was conducted in Shanghai as the research object of a bank,adopted the method of empirical analysis and statistical survey factors affecting bank training effect.The results show that organizational factors on the influence of the training effect was the most obvious, followed by training system factors and personal factors.


In two studies, participants read a story and then completed a multiple choice recognition test assessing recall for facts from the story. After answering some of the recognition test items, participants were shown a tally of other participants' responses to the same items. However, these bogus tallies were controlled by the experimenter. Later, participants' memory for story facts was again assessed, this time using a cued recall test. The data indicate that participants' memory responses on the story cued recall test sometimes changed from the memory responses given on the initial story recognition test. The changes often matched the most frequent response given by the bogus others. This effect was more likely when apparent agreement among the bogus responses was high, and less likely when item memorability was high. In Study 1, evidence of such response alterations was still present, even when recall for others' responses was taken into account. In Study 2, these response alterations were observed even...


This research was aimed to study the adsorption of Alizarin Red S (ARS) dye using graphene oxide (GO) as an adsorbent compared with bare graphite powder (BGP). For optimum conditions, the effects of the initial concentration of ARS, solution pH, adsorbent dosage, and contact time were investigated in detail. The optimum conditions for this work were consisted of 350 mg/L initial concentration of ARS with 0.02 mg adsorbent at pH 2.0. The adsorption equilibrium was completely reached within 30 min. The maximum adsorption capacity of GO was 88.50 mg/g which was higher than that of BGP (34.13 mg/g). The adsorption kinetics well fitted using a pseudo second-order kinetic model. The intraparticle diffusion model described that the intraparticle diffusion was not the only rate-limiting step. In thermodynamics diversion, changes in free energy (DG), enthalpy (DH) and entropy (DS) were also evaluated. The overall adsorption process was exothermic and spontaneous in nature. The adsorption isotherms for GO and BGP fit well with the Langmuir and Freundlich models, respectively. It is, therefore, evident that the as-prepared GO can be used as a high potential adsorbent for the anionic dye and it can be reused for fourth time of adsorption.


Since the late 1980s, Americans have been inundated with media reports describing the increasingly dire circumstances surrounding our nation's children. Families in the United States are beset by urgent problems, including poverty, teenage pregnancy, single parenthood, substance abuse, limited health care, and inadequate and unaffordable housing. Even though these problems are not strictly educational issues, they do impact all aspects of children's lives, placing them at risk of educational failure?As a result, they place schools at the center of interconnected social problems. As they traditionally have, non-school-based service providers, including public and private community agencies, can provide services for at-risk children and their families. These services include counseling, financial assistance, medical treatment, and job training. Increasingly, however, many of these agencies are subjected to heavy caseloads, limited resources, and isolation from other related service providers. ~ On the other hand, many professional groups now agree that the complex problems of at-risk children and their families cannot be tackled by our schools alone? Rather, broader social policies must be established to protect the nation's at-risk children and their families. One response to the call for broad social policies has been the establishment of interagency, collaborative programs that link schools and other service agencies, drawing upon the strengths of each in an effort to meet the educational and social needs that neither can effectively


An asymmetric large optical cavity (LOC) waveguide is designed to raise the output power of the 940 nm laser diode. By optimizing the metal organic chemical vapor deposition growth condition and combining with the electrode fabrication and facet coating, single emitter semiconductor laser diodes of 95 mm strip width and 4 mm cavity length are fabricated. Without any active cooling process, an output power of 13.4 W is reached at 15 A injection current without catastrophic optical mirror damage at room temperature. By introducing the asymmetric LOC waveguide, the far-field test shows that only the transverse fundamental mode is lased with a vertical far-field angle full width of half magnitude of 22o.

The present paper is written with no pretence at finality, and consequently some excuse is due for its publication at the present time. The author was induced to write it since the results so far obtained by him do not seem to agree, in all points, with the work previously done on the subject, and tend to show that there is much scope for future work both on this matter and also on a matter of much greater general importance, namely, on the influence of external conditions on a quantitative character.


permeated lymphatics which formed the lines of communication." The embolic theory of bone infection by the blood stream deemed the entry of the nutrient artery to be the sites of spontaneous fracture or growth. If the humerus and femur are invaded from the lymphatic plexus of the deep fascia, as Mr. Handley believes, the first attack, he says, should be directed on that point at which the bone lies nearest to the deep fascial lymphatics, and therefore on that point at which the bone comes nearest to the cutaneous surface. Moreover, where the bone is provided with two or more subcutaneous areas, the seat of the first attack, according to the view of centrifugal spread, must be that area which is nearest to the trunk. On this hypothesis the point of invasion should be, and Mr. Handley says is, in the femur, the base of the great trochanter, and the adjoining part of the linea aspera. The point of invasion of the lhumerus should be, and actually is, relatively much lower down, at the deltoid insertion, since the whole of the upper half of the humerus is well clothed with muscles. Mr. S. Paget asks, "Whlio has ever seen the bones of the hands or feet attacked by secondary cancer?" Mr. Handley's answer to this is that no patient lives long enough for centrifugal invasion to reach the distant parts. Mr. Handley points out that the anatomy of the epigastric region strongly suggests the likelihood of the mode of invasion of the abdominal cavity. According to Stiles, tlle lower and inner margin of the breast lies over the sixth costal cartilage; that is to say, this part of the mammary circumferenee is only about an inch from the interspace between the ensiform cartilage and the seventh costal cartilage. Therefore, as soon as parietal permeation has extended little more than an inch beyond the edge of the breast the cancerous lymphatics of the deep fascia are no longer separated from the stibserous fat (subperitoneal or subpleural) by a bony cage covered by thick muscles, but simply by a single layer of fibrous tissue traversed by lymphatics. At the tip of the ensiform cartilage the transversalis fascia is hardly recognizable as a distinct layer, and the parietal lymphatic plexus is separated from the subperitoneal fat simply by the linea alba. It is not surprising if through this obviously weak spot cancer frequently reaches the peritoneum before it lhas' succeeded in reaching the pleura, even at points directly subjacent to the primary focus. Before any operation for the removal of cancer of the breast is undertaken, Mr. Handley advises that a careful examination of the epigastric region shouild be made to see if there is any tenderness or pain there. The presence of tenderness or pain should raise the suspicion that epigastric invasion had already occurred, and in such cases the liver should be carefully palpated when the patient is under the anaestlhetic before the breast is removed, and he goes on to say that it must never be forgotten that the first sign of epigastric invasion may be found not in the epigastric region, but in the pelvis from the gravitation of cancerous particles into it; a vaginal and rectal examination should, he thinks, be made pi-ior to operation. In operating for removal of breast cancer Mr. Handley strongly advises that the site of the growth be made the centre of a circle from wllich the deep fascia is to be removed. The skin flaps should be raised till a circle 10 to 12 in. in diameter with the primary growtlh for its centre is exposed. The exact anatomical limits of this dlissection will, of course, vary witli the situation of the growth in the breast. Au aninular incision, marking out tlle 10-in. circle of deep fascia to be removed, is carried down to the muscles through the deeper subcutaneous fat close to the base of the skin flaps. Inthe lower part exposed by this wide raisinig of the slini flaps the anterior layer of the rectus sheath on both sides of the middle line should be raised up and removed wvith the deep fascia, for it is specially in this region tllat inifection of the peritoneal cavity may occur. After dividing the pectoral muscles, exposing the costo-coracoid membrane, and clearing the apex of the axilla, thle whole ma-ss is turned outwards, and where the digitations of serratus magnus lie in contact wvith the deep surface of the breast they should be removed together wTith a superficial layer of thle digitations of external oblique. The theory of infection, even of distal parts, by way of the lymphatics, commends itself strongly, but the question still is whether this is the only source of infection. Sir George Beatson of Glasgow, who has done much and good work on breast cancer, pays a tribute to Sampson Handley for the work he has done in outlining the limits of the lymphatic system and its distribution, but does not agree with him in his permeation theory, and feels there is more than that needed to explain all that is found, and takes the view that pressure dissemination represents more clearly what takes place. Mr. G. L. Cheatle, in several interesting papers, draws attention to the fact that there seems to be a certain relation between nerve supply and the growth of cancer, and that there seems a greater tendency for the disease to spread along the area of the particular nerve distribution in which it first occurred rather than inde. pendently into neighbouring areas. Mr. Cheatle also states that he has been able to demonstrate that inflammatory changes occurred in two po0t-mortem cases in the spinal ganglion, on the cutaneous distribution of whiclh the cancer had begun, whilst the ganglia into whose cutaneous distribution the cancer had spread showed tlle changes of degeneration which had been noted both by Lugaro and himself, and points out that in the two cases described the cancer began on parts of the skin where nerves become cutaneous. If the lesions in the ganglia were secondary to the lesions of the skin, then Mr. Cheatle thinks that there would also have been secondary inflammatory changes in all the ganglia whose peripheral branches were involved in the lesion, but he found that this was not the case, although these particular branches had been involved for many years. Mr. Cheatle puts three pertinent questions which certainly ought to be borne in mind in investigating cancer, namely: 1. Is the inflammatory change within the posterior spinal root ganglia in any wayconnected with origin or spread of cancer ? 2. If it is, did it exist before the cancer began? and hence had it anything to do with the genesis or point of incident ? 3. If it occurred secondarily to the cancer, had its presence anything to do with the spread of that disease ? The theory of the spread of breasb cancer brought for. ward by Mr. Handley offers a much more hopeful prognosis in early cases than has hitherto been possible, but still Sir WVatson Cheyne's advice given some years back, namely, that in the first operation lies the patient's only chance, and that it must therefore be done with the greatest thoroughness, however limited the disease may be at the time of operation, is as true now as ever it was.


Motion estimation is the most time consuming part of the video coding because of its complexity. A novel fast block matching motion estimation algorithm named Long-Rood fast motion estimation algorithm based on starting search point prediction is proposed for real-time video coding. A number of standard test sequences are adopted for performance comparison of the proposed algorithm and Full Search (FS), Three-Step Search (TSS), Diamond Search (DS) and Adaptive Rood Pattern Search (ARPS) algorithms.The experimental results show that the proposed algorithm is about 3.29~17.24 times faster than that of TSS, 1.71~9.05 times faster than that of DS, and 1.24~4.45 times faster than ARPS, while the Peak Signal-to-Noise Ratio (PSNR) is almost the same or a little higher than the other algorithms.


The present study aimed to examine whether visual contact with natural imagery would result in reduced levels of anxiety in older people, when compared with the effects of urban imagery. Thirty-three older adults between the ages of 61 and 91 participated in this study. Thirteen of the participants were male and 20 were female. In a partial replication and extension of the work of Ulrich et al. (1991 ), the participants were randomly assigned to one of three groups a nature video group, urban video group or control group. All participants initially completed the state form of Spiel berger' s (1983) State-Trait Anxiety Inventory (STAI). Then sevenminutes worth of a nature video (depicting rainforests) or an urban video (depicting cityscapes) was shown to those in the experimental groups. Those in the control group were left in a room containing magazines for a seven-minute period. The state form of the STAI was then re-administered to all participants. A Kruskal-Wallis test was conducted on the data and indicated that no statistically significant differences existed between post-test STAI scores for the nature, urban or control groups (p > .05). These results are in contrast to those found in the previous literature and suggest that limitations such as the small sample size, nature of the sample and the length of the video recordings may have been at least partly responsible for the nonsignificance of the results. Because of the potential for this area of research to improve the quality of life and health of older Australians, future research should concentrate on overcoming research limitations and methodological problems. Findings could then be applied for the benefit of older people in a wide range of environments, such as nursing homes, hospices, hospitals and retirement communities.

Background: The success of a single maxillary denture in Combination syndrome relies on the principles of retention, stability and support. Severely resorbedmaxillary edentulous ridges that are narrow and constricted with increased inter ridge space will affect this success.Subjects and Methods: Ten patients with a Combination syndrome suffering from narrow anterior maxilla and mandibular Kennedy Class I were included in this prospective clinical study. Patients were randomly divided into two groups. Group I received four Xive implants supported and retained complete maxillary overdenture with the anterior maxilla augmented with autogenous bone block chin graft. Group II received four Xive implants supported and retained complete maxillary overdenture with the anterior maxilla augmented with vertical ridge splitting and heterogenous bone fill particles of lyophilized deantigenized animal equine collagen, and biocollagen resorbable membrane.Results: The results of this study revealed nonsignificant increase in the mean bone height loss after 6, 12 and 18 months follow up period in group I and group II. There was a non-significant difference in the mean bone height loss between group I and group II at different follow up periods.Conclusions: After one and a half years of implant retained and supported overdenture, clinical and radiographic data demonstrated that implants can be successfully placed in either alveolar ridges augmented with autogenous bone or ridge splitting with Bio-Gen and Biocollagen membrane. Also, this study exhibited peri-implant stability with high survival, healthy peri-implant tissue and the marginal bone ridge values were satisfactory around implants.

Reproductive allocation strategies have been historically described as lying on a continuum between capital and income breeding. Capital breeders have been defined as species that allocate stored reserves to reproduction, whereas income breeders have been defined as species that allocate relatively recently-ingested food resources to reproduction. Snakes are considered capital breeders because they efficiently store large amounts of nutrients and energy, potentially enough to support an entire reproductive bout without feeding. We examined the abilities of five viviparous snake species to allocate income to follicles during vitellogenesis. We fed 15N-labelled L-leucine to experimental females of each species during vitellogenesis, whereas control females were fed unlabelled meals. After ovulation, we measured yolk 15N p.p.m. using mass spectrometry. Maternal scale samples taken before labelling were used to estimate endogenous 15N concentrations, which should represent 'capital'. Scale samples taken at ovulation were used to determine whether snakes assimilated 15N-labelled-leucine from labelled diets. Yolks and post-ovulatory scales of labelled females were significantly more enriched in 15N than those of unlabelled females in all species, indicating significant assimilation and allocation of income-derived amino acids to the yolk during vitellogenesis. The lack of among-species differences suggests that all species allocated income amino acids to vitellogenesis. The results obtained in the present study suggest that proportional utilization of income or capital depends on the frequency and timing of foraging success during reproductive events. Therefore, capital and income breeding may be consequences of both life-history and environmental constraints on foraging success, rather than strategies of reproductive allocation. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 106, 390–404.

In this study, we investigate the positive aspects of the interface between work and family by examining the relationship between work-family enrichment and work-family satisfaction outcomes. Employees (N = 336) at a national retail chain completed a survey questionnaire. Hierarchical multiple regression analysis showed that work-to-family enrichment explains a significant proportion of the variance in both job satisfaction and career satisfaction and that the affective component of family-to-work enrichment explains a significant proportion of the variance in family satisfaction. Implications for both work-family theory and management practice are discussed.

The study tested the control-value theory's (Pekrun, 2006; Pekrun, Goetz, Titz, & Perry, 2002) assumptions regarding the cognitive-motivational effects of emotions on achievement. Specifically, the link between critical thinking and achievement was examined among 220 engineering students. The Academic Emotions Questionnaire (Pekrun, Goetz, & Frenzel, 2005) was used to assess how specific negative academic emotions mediated the effect of critical thinking on achievement. Results showed that critical thinking was positively associated with achievement, but negative emotions (anger, anxiety, shame, boredom, and hopelessness) were negatively correlated with achievement. Anxiety and hopelessness were found to completely mediate the relationship between critical thinking and academic achievement. The results suggested that when students engage in critical thinking, their cognitive resources are used appropriately for the task to be completed, making them less anxious and less hopeless, thereby increasing their achievement.


To investigate the clinical value of Pre-S1 antigen detection in the diagnosis of hepatitis B virus, the Pre-S1, HBeAg and HBV-DNA levels in 650 HBV-M serum samples with different positive models and 40 HBV-M all negative serum samples were detected by using ELISA and fluorescence quantitative PCR (FQ-PCR). The results showed that the Pre-S1 positive rate was 92.4% and HBV-DNA positive rate was 100% in 119 cases of Da san Yang samples; the Pre-S1 positive rate was 42.5% and HBV-DNA positive rate was 63.4% in 186 cases of Xiao san Yang samples. The Pre-S1 positive rate was 47.6% and HBV-DNA positive rate was 66.7% in 21 cases of HBsAg and HBcAb positive group samples. The Pre-S1 positive rate was 0.4% and HBV-DNA positive rate was 0% in the 297 cases of HBsAb positive samples. The pre-S1 positive rate was 79.3% in 268 cases of HBV-DNA positive samples. The positive rate of Pre-S1 and HBV-DNA positive rate in 40 cases of HBV-M all negative model samples were 0%. The positive rate of Pre-S1 in Da san Yang, Xiao San yang and HBV-DNA positive samples were significantly higher than that of other negative group(P0.01 ). The detection of Pre-S1 could have complementary role and improve the hepatitis B two pairs of semi, in particular on the HBeAg negative or HBV-DNA mutation patients. It could better reflect the state of hepatitis B viral replication and infectious.


Osteoarthritis of the midfoot is a common complaint within modern orthopaedic practice. Patients usually present with significant pain, loss of function, and occasionally, deformity. The leading causes of midfoot arthritis include primary degenerative arthritis and posttraumatic joint degeneration. We present 2 cases of patients with a stress fracture of the navicular on a background of primary degenerative arthritis. There was no history of trauma, and fracture was not initially visible on plain x-ray in either case. We believe osteoarthritis-associated navicular stress fractures may be underreported in the literature.


Background:
 Prior studies demonstrated a higher risk of acute cardiovascular disease (CVD) around population-wide psychosocial or environmental stressors. Less is known about the impact of sociopolitical events. The objective of the current study was to examine acute CVD hospitalizations following the 2020 presidential election.

 Methods:
 We examined hospitalizations for acute CVD around the 2020 presidential election, among adults enrolled in Kaiser Permanente Southern and Northern California, two integrated health care delivery systems that provide care for >9 million persons. CVD was defined as hospitalizations for acute myocardial infarction (AMI), heart failure (HF) or stroke. Rate ratios (RR) and 95% confidence intervals (CIs) were calculated comparing rates in the five days following the 2020 election to the same five days two weeks prior.

 Results:
 Among 6,396,830 members ≥18 years, rates of hospitalization for CVD following the election (666 hospitalizations; rate = 760.5 per 100,00 person-years [PY]) were 1.17 times higher (95% CI 1.05, 1.31) compared to the same five days two weeks prior (569 hospitalizations; rate = 648.0 per 100,000 PY). (Table) RR for AMI, stroke, and HF were 1.42 (95% CI 1.13, 1.79), 1.02 (95% CI 0.86, 1.21) and 1.18 (95% CI 0.98, 1.42), respectively.

 Conclusions:
 Higher rates of acute CVD were observed following the 2020 presidential election. Awareness of the heightened risk of CVD and strategies to mitigate risk during significant sociopolitical events are needed.


The ecological compensation has developed to some degrees,but it still has not formed as integral system from the aspect of law and rules.The law connotation should be identified first,and the flaws of law and systems are exposed,such as single source of compensation funds and poor public environmental awareness.It proposes that law behavior of ecological compensation should be normalized,mutual-channels of funds should be implemented and environmental awareness for public should be popularized and public involvement system should be perfected.


A study was conducted during Zaid 2005, in Uttar Pradesh, India, to evaluate the nature and magnitude of genetic divergence in 30 bitter gourd genotypes. Results revealed the presence of wide genetic diversity. The genotypes were grouped into 6 clusters based on Mahalanobis D statistics using Tocher's 2 method. The clustering pattern of genotypes revealed that the genetic diversity was independent of the geographical diversity. Among the 6 clusters, maximum numbers of genotypes were found in cluster V, while clusters III was found to be mono-genotypic. Among the 12 quantitative characters studied, individual fruit weight constituted a maximum of 64.14% contribution to the divergence, followed by days to first female flower appearance. Ranking of genotypes based on intra-cluster mean performance for these characters which are major contributors of genetic diversity revealed its usulness in selecting parents for heterosis breeding.


Idiopathic inflammatory myopathies (IIMs) are heterogenous systemic autoimmune disorders that mainly affect the skin, muscles, and lungs. Whereas cardiac involvement is considered to be rare, it causes cardiac inflammation and fibrosis leading to severe morbidity and mortality. However, little is known about clinical characteristics and risk factors for cardiac involvement in patients with IIMs.The aim of this study was to clarify the frequency and clinical characteristics of cardiac involvement and its risk factors in patients with IIMs.We retrospectively reviewed consecutive patients with IIMs who visited Keio University Hospital from 2002 to 2022. We divided patients into two groups according to the presence or absence of symptomatic cardiac involvement and compared their clinical characteristics and autoantibodies between the two groups. We defined symptomatic cardiac involvement as the presence of chest pain, palpitation, cardiogenic leg edema, or respiratory distress accompanied by abnormal findings of cardiac examinations such as electrocardiography, echocardiography, and/or cardiac magnetic resonance imaging (MRI).We included 145 patients with IIMs in the analysis. The mean age at IIMs diagnosis was 55 years old, and 71.7% were female. Forty patients (27.6%) were polymyositis, 53 (36.6%) were dermatomyositis, 44 (30.3%) were amyopathic dermatomyositis, and 8 (5.5%) were immune-mediated necrotizing myopathy. Among them, 52 patients (35.9%) had abnormal findings on electrocardiography, echocardiography, and/or cardiac MRI, and 17 (11.7%) were diagnosed with symptomatic cardiac involvement at the mean age of 65 years during the mean observation period of 20.0 years. Comparison of clinical characteristics identified no difference in the mean age, sex distribution, and duration from IIM diagnosis to symptomatic cardiac involvement between the two groups. Also, no significant difference was found in the positivity of anti-amynoacyl tRNA synthetase antibody, anti-MDA5 antibody, and anti-SS-A antibody, IIMs subtypes, presence of skin rash, malignancy, interstitial lung disease, history of cyclophosphamide use, and maximum levels of CK, aldolase, CK-MB, troponin T, and CRP. However, the presence of Raynaud's phenomenon and neutrophil/lymphocyte ratio at diagnosis were significantly higher in the cardiac involved group compared to the non-cardiac involved group (53.85% vs 15.24%, p=0.0009; 56.25% vs 18.25%, p=0.0006). Multivariable analysis identified Raynaud's phenomenon (odds ratio [OR] 8.42, 95% confidence interval [CI] 2.10-33.8, p=0.0026) and elevated neutrophil/lymphocyte ratio (OR 6.92, 95% CI 1.73-27.6, p=0.0061) as independent risk factors for symptomatic cardiac involvement. One patient in the cardiac involved group died of cardiac failure during the observation period.Abnormal findings in cardiac examinations and symptomatic cardiac involvement are frequent in patients with IIMs. Evaluating cardiac involvement is important, especially in patients with Raynaud's phenomenon and elevated neutrophil/lymphocyte ratio at diagnosis.[1]Lilleker JB, Vencovsky J, Wang G, et al.

The paper presents investigations of physical and climatic factors with regard to design and process variables having effect on heat transfer in the building model system at different distances between them in the airflow direction. The aim of this work is to improve energy efficiency of exterior walls of buildings. A method of physical simulation was used in experiments. Experimental results on the average values of the heat transfer coefficient in the building model system are presented herein. A series of experiments was carried out on a specific aerodynamic test bench including a subsonic wind tunnel, heat models and devices for giving thermal boundary conditions, transducers, and the record system equipment. The paper contains diagrams of the average heat transfer distribution at fixed Reynolds number and the airflow angle of attack; the average values of the heat transfer coefficient for each face and wind tunnel models as a whole at maximum, medium, and large distances between them. Intensification of the average heat transfer was observed on the downstream model faces depending on the distance between models.


An efficient rearing process, consisting of pre-weaning, weaning and postweaning
phase is integral to any operation seeking herd replacements. The
results of multiple publications focusing on different aspects of calf development
were reviewed and compared. Throughout the rearing process the calf's
development is influenced heavily by the feeding treatment, and consequent
nutritional level. This can effect calf development as early as the fetal stage.
Intensive and ad libitum feeding treatments during the pre-weaning phase can
lower mortality rate, while also helping to achieve an early onset of puberty,
target weights for insemination, an optimal age at first calving and an increased
lifetime productivity. Feeding milk replacer instead of whole milk when
employing these treatments may mitigate the risk of fat deposition, ensuring
proper mammary development. Additionally, combining intensive or ad libitum
feeding treatments with a step-down weaning plan can work to mitigate postweaning
growth depression. Feedstuff that results in an increased production of
volatile fatty acids has a significant positive influence on rumen development,
although dietary fiber needs to then be included to buffer rumen pH. Housing
calves in groups may have the benefit of increasing animal welfare and results
in the exhibition of more natural and social behaviors. Nonetheless, all efforts in
optimizing management decisions to improve calf development can be
rendered obsolete if proper hygiene is not enforced, resulting in disease
outbreaks and increased mortality rates.


Background Blood pressure variability (BPV) is a reliable prognostic factor for cardiovascular events. Currently there is a worldwide lack of large sample size studies in visit‐to‐visit BPV. Based on the Kailuan Study, we analyzed the visit‐to‐visit BPV of patients to investigate the range and influencing factors of BPV. Methods In 11 hospitals in the Kailuan Company, 4 441 patients received routine health checkups. Physical examination measured blood pressure (BP), body height, body weight, and waist circumference, and body mass index was calculated. Blood samples were analyzed for plasma total cholesterol (TC), triglyceride (TG), high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol (LDL‐C), fasting blood glucose (FBG), and high‐sensitivity c‐reactive protein (hs‐CRP). Results The effect of gender on systolic BPV was investigated. The average systolic BPV was 10.35 mmHg (1 mmHg= 0.133 kPa) overall, 10.54 mmHg in males and 10.06 mmHg in females. Multivariate Logistic regression analysis revealed that the age (RR=1.022), systolic BP (SBP, RR=1.007), LDL‐C (RR=1.098), and history of hypertension (RR=1.273) were significant risk factors for higher systolic BPV. We found that aging (RR=1.022), increased SBP (RR=1.007), and a history of hypertension (RR=1.394) were determinants of systolic BPV in males. The risk factors for systolic BPV of females were aging (RR=1.017), increased SBP (RR=1.009), increased LDL (RR=1.136), and increased TG (RR= 1.157). Conclusion Our findings indicated that the systolic BPV is closely associated with age, SBP and history of hypertension.


The chemodynamical evolution of spherical multi-component self-gravitating models for isolated dwarf galaxies is studied. We compared their evolution with and without feedback effects from star formation processes. We found that initially cuspy dark matter profiles flatten with time without any special tuning conditions as a result of star formation. Thus the seemingly flattened profiles found in many dwarfs do not contradict the cuspy profiles predicted by cosmological models. We also calculated the chemical evolution of stars and gas, to permit comparisons with observational data.


In this paper, the proposed antenna design is a conventional rectangular-shaped microstrip patch antenna with partial ground plane to operate at 10.5 GHz. There are some inherent disadvantages of conventional microstrip antennas such as narrow bandwidth, low gain/ directivity, low efficiency, etc. The proposed design is optimized and converged using Particle Swarm optimization (PSO) to overcome these limitations. This antenna is constructed using FR4 substrate material having dielectric constant of 4.3. The dimension of the proposed antenna is 25.81 mm $\times$ 23.08 mm $\times$ 1.58 mm. This antenna provides sufficiently large simulated bandwidth of 1.95 GHz (9.71-11.66 GHz) and measured bandwidth of 1.55 GHz (9.66-11.21GHz). The values of return loss is −28.40 dB (simulated) and −23.02 dB (measured) at 10.5 GHz. The simulated radiation patterns show the omnidirectional radiation characteristics. The proposed antenna exhibits higher simulated values of gain (4.07dB) and directivity (5.01dB) at 10.5 GHz.


DECLIC, a Facility dedicated to the study of transparent media under microgravity, will be used in an ISS EXPRESS Rack. This paper focuses on the EXL which contains two optical boxes disposed on two opposite sides of the cavity where the Inserts to be studied shall be locked. At the moment, three types of inserts are planned to be accommodated in the EXL. Various optical diagnostics are available by configuring the EXL (sources, sensors, mechanisms). After the presentation of the EXL design, this article deals with some manufacturing and testing aspects, such as the use of COTS (cameras). Specific OGSE have been developed in order to simulate the optical interfaces and the propagation of beams in the inserts. Three models of the EXL have been integrated and fully tested, including the Flight Model. The sequence of tests, the performances measured, and then some images of the experiments performed with the inserts will be presented.


As early as in 1953 it was reported that at low relative humidity of the atmosphere (about 70 %) DNA films were in A-form, while at higher humidity (more than 80%) they were in B-form. Relative humidity of the atmosphere corresponds to the water activity in the system. It was found in the beginning of the 70th that DNA transfers to the A-form when non-electrolytes, such as monoatomic alcohols, dioxane, tetrahydrofurane were added to water. It was reasonable to suppose that B to A transition of DNA occurs in the non-electrolyte solutions at the same values af water activity as in the moist atmosphere. This prediction was borne out. But in water solutions of very polar non-electrolytes such as methanol and ethylene glycol B to A DNA does not occur even at very low water activity values. It was supposed that A form of DNA can arise only in the medium with sufficiently low polarity. We used hyperfine splitting constant (A) of a nitroxide spin label determined from the EPR spectra as a measure of the liquid solvent polarity. It was found that DNA transition into B form occurs when A reached a certain value. Polarity of methanol and ethylene glycol is much higher than that of the solutions in which B to A DNA transition takes place. This transition also occurs in water solutions of trifluoroethanol. But in these solutions the transition takes place at hyperfine splitting values, which are much greater than in other non-electrolyte solutions. Water activity in the zone of B-A DNA transition in trifluoroethanol solutions does not correspond water activity which was calculated for other nob-electrolyte solutions in which B-A transition is observed.


Abstract : The change-point problem can be considered one of the central problems of statistical inference, linking together statistical control theory, theory of estimation and testing hypotheses, classical and Bayesian approaches, fixed sample and sequential procedures. It is very often the case that observations are taken sequentially over time, or can be intrinsically ordered in some other fashion. The basic question is, therefore, whether the observations represent independent and identically distributed random variables, or whether at least one change in the distribution law has taken place. This is the fundamental problem in the statistical control theory, testing the stationarity of stochastic processes, estimation of the current position of a time-series, etc. Accordingly, a survey of all the major developments in statistical theory and methodology connected with the very general outlook of the change-point problem, would require review of the field of statistical quality control, the switching regression problems, inventory and queueing control, etc. The present review paper is therefore focused on methods developed during the last two decades for the estimation of the current position of the mean function of a sequence of random variables (or of a stochastic process); testing the null hypothesis of no change among given n observations, against the alternative of at most one change; the estimation of the location of the change-point(s) and some sequential detection procedures.

An orthosis for treating muscle disorders of the elbow has a body made in one piece from a semi-rigid material. The body includes a distal portion, a proximal portion, and a back joining strap. In the unstressed state, the relative position of the distal and proximal portions maintains the wrist in an extended state. The joining strap is deformable such that when pressure is exerted downward on the palm support, the joining strap is deformed to enable the pivotal movement of the distal portion with respect to the proximal portion about a transverse articulation axis parallel to the flexion-extension axis of the wrist. When pressure is released, the body returns to the unstressed state due to resilience. The distal portion is arranged to pivot with respect to the proximal portion about the articulation axis while assisting the extensor muscles of the wrist.

What does it mean to be "indigenous"? Is indigeneity a matter of physical "space"? Or is it a cognitive-cultural "place"? Or both? How do Islanders negotiate indigeneity in a time of transnational and interisland migration and cultural conflict? I examine these and related issues through the lens of recent events in the Solomon Islands, including the historical pattern of interisland migration, the recent ethnic cleansing cultural rupture, and the resulting dialogue about identity and indigeneity among Solomon Islanders living abroad and at home via the internet.


This paper presents a diagnostic test generation method for transition faults. As two consecutive vectors application mechanism, launch on capture test is considered. The proposed algorithm generates test vectors for given fault pairs using a stuck-at ATPG tool so that they are distinguished. If a given fault pair is indistinguishable, it is identified. Therefore the proposed algorithm provides a complete test generation regarding the distinguishability. The conditions for distinguishing a fault pair are carefully considered, and they are transformed into the conditions of the detection of a stuck-at fault, and some additional logic are inserted in a CUT for the test generation. Experimental results show that the proposed method can generate test vectors for distinguishing the fault pairs that are not distinguished by commercial tools, and also identify all the indistinguishable fault pairs.


The binding reaction mechanism between different forms of chromium ion and bovine serum albumin(BSA) was investigated using affinity capillary electrophoresis(ACE) method,and a comparative analysis was carried out.An interaction model of the ligand(Cr(Ⅲ) and Cr(Ⅵ)) binding with the receptor(BSA) was established under simulated physiological conditions.Based on the changes of effective mobility of BSA,the apparent binding constants of Cr(Ⅲ)-BSA and chromium(Ⅵ)-BSA were calculated by a nonlinear fitting equation and the differences of binding reaction between chromium(Ⅲ) and chromium(Ⅵ) with BSA was quantificational characterized.The results showed that the obvious valence correlation existed between the binding reactions of Cr(Ⅲ),Cr(Ⅵ) and bovine serum albumin(BSA),and with the changes of concentrations of Cr(Ⅲ) and Cr(Ⅵ),the obvious dose-effect relationship existed between metal Cr irons with BSA.A conclusion about a quick balance system of the binding reaction between Cr(Ⅲ) and Cr(Ⅵ) with BSA was also acquired by analyzing electropherogram.This work has a referential meaning for the further analysis of the binding reaction mechanism of different metal iron forms and protein molecule.


Background: Previous randomized controlled trials have demonstrated that omega‐3 polyunsaturated fatty acids (n‐3 PUFA) are beneficial in reducing symptoms of depression. However, there is limited evidence regarding the influence of dietary n‐3 PUFA intake on mood in adolescents drawn from population studies. Objective: In the present investigation, we examined the relationship between dietary n‐3 PUFA intake on depression symptomatology in a large prospective pregnancy cohort followed for 17 years. Methods: Adolescents enrolled in the Western Australian Pregnancy Cohort (Raine) Study completed a Food Frequency Questionnaire to assess dietary fatty acid intake, as well as other dietary factors at age 14 and a fasting blood sample was taken. Participants also completed the Beck Depression Inventory for Youth (BDI‐Y) at age 14 (N = 1,407) and at age 17 (N = 995). Results: An inverse relationship was observed between intake of both saturated fat and of n‐3 PUFA at age 14 and BDI‐Y scores at both 14 and 17 years of age. However, after adjusting for energy (kJ) intake and other lifestyle confounders, the relationships were no longer significant. Conclusions: Associations previously reported between n3 PUFA and depressive symptoms may be due to collinearity with other dietary and lifestyle factors.

ABSTRACT This article examines low-income parents' monetary investments in their young children, asking how low-income families are able to afford spending on children. We investigate parental spending on child care and on goods in the home that may provide enrichment for young children. We find little evidence that households make spending trade-offs for either type of good. Instead, our results suggest that low-income households that can afford child care may be poor only temporarily and that they spend primarily when they are unable to avoid doing so because of family work patterns. For enrichment goods, parental education is a stronger predictor of spending.

In the activities of the Pratama Insinas, Ministry of Higher Education technology research in 2018, PTKRN BATAN built a testing facility that simulates a passive cooling system on the reactor core when there is a loss of outside power. The test facility is the Passive-02 System Simulation Facility (FASSIP02).In FASSIP-02 there are several parameters that need to be measured, one of which is temperature. In the measurement of temperature using a K type Thermocouple Connected to the National Instrument 9178 and 9213 modules that use computer programming with LabVIEW software. Temperature measurements need to be characterized.Characterization of type K thermocouples was carried out using thermobaths, 30 type K thermocouples, standard thermocouples,National Instrument modules 9178 and 9213 with computer programming displays using LabVIEW software. The method used for characterization oftype K thermocouples is a fixed temperature comparison method where the results of the temperature control of thermobath is 30-90 ͦC compared with the results of measurements from the type Kthermocouple and standard thermocouple. From the difference of the copper-wrapped junction tip thermocouple without the copper-wrapped and standard thermocouple produces a small error value, so the use of copper as a thermocouple junction end wrapper can be used as a temperature measurement FASSIP-02.

From 1952 to 1960 at Swift Current, Saskatchewan, the performance of a grass-alfalfa mixture was compared to that of oats and of wheat on dryland, principally from the standpoint of hay production. Average annual hay yields over the 9-year period were similar, but within single years large differences in yield occurred between crops. In seasons with favourable precipitation the perennial forage mixture gave higher hay yields, while the cereals gave the highest yields during very dry seasons.Small yields from the perennial crop were associated with low rainfall in May. It was concluded that perennial forage crops should be the main source of winter feed in a semi-arid climate, if used in conjunction with a cereal crop for insurance.

Objective: To investigate the expression of Cyclin E,CDK-2 and their inhibitors P27KIP1and P21WAF1/CIP1in gestational trophoblastic disease(GTD). Methods:Expression of the above indexes were determined immunohistochemically by specific antibodies for these proteins on formalin-fixed paraffin sections of 30 of normal placenta tissues,38 of hydatidiform moles and 9 of gestational trophoblastic neoplasms(GTN), including 8 invasive moles and 1 choriocarcinoma. Results:①The expression of Cyclin E and CDK-2 in GTD was significantly higher than that in normal placentas(P0.01). The expression of P27KIP1and P21WAF1/CIP1in GTN was significantly lower than that in hydatidiform moles and normal placenta tissues,respectively(P 0.05). Moreover,the expression of P27KIP1 and P21WAF1/CIP1 in hydatidiform moles which developed GTN was significantly lower than those spontaneously regressed. ② Significant negative correlations between the Cyclin E and P27KIP1,P21WAF1/CIP1staining indexes were observed(P0.05). There was a positive correlation between the expression of CDK-2 and Cyclin E(P 0.05). Also,the expression of P27KIP1 and P21WAF1/CIP1 showed positive correlation(P 0.05). CDK-2 showed inverse expression pattern compared with P27KIP1and P21WAF1/CIP1,but no statistical difference was observed(P 0.05). Conclusions:Disregulation of Cyclin E/CDK-2 complex and its inhibitors participated in the development of gestational trophoblastic tumor.P27KIP1and P21WAF1/CIP1may be used as effective indicators for the prognosis of hydatidiform moles.


Since the Yuan period (1279–1368), imperial states have moved several million Chinese people to Yunnan, establishing a new demographic pattern and transforming local society. Central administrative hierarchy, migrants, taxation, education, and economic and religious infrastructures introduced Chinese institutions into Yunnan, leading to the so-called sinicization (huahua) of the region. At the same time, native peoples' myriad influences on the Chinese immigrants served as a sort of indigenization (tuzhuhua) of the immigrants. Sinicization and indigenization were two sides of the process through which a middle ground was negotiated.


This research examined the applicability of the Medieval Kingdom social role topology (Adcock & Segal, 1983) with kindergarten children and assessed the association between the social roles children assumed and seven nonbehavioral variables. One hundred and seventy-three children from 10 kindergarten classes in two schools participated. Hypotheses that the Medieval Kingdom topology could be distilled from a sample of kindergarten children and that specific nonbehavioral variables including cognitive ability, physical attractiveness, self-esteem, and chronological age were related to the assumption of leadership roles within the topology were confirmed. Children's gender, birth order, and number of siblings were not found to influence the status within the social hierarchy. The findings suggest that the Medieval Kingdom is a potentially useful heuristic for understanding the peer relationships of young children.
