In this paper, a novel channel estimation technique for intelligent reflecting surface (IRS)-aided single-user multiple-input multiple-output (SU-MIMO) systems is proposed. Based on dominant single-path channel approximation for IRS-related channels, the proposed technique conducts parameter estimation instead of straightforward full channel estimation. This makes the proposed technique practical with low training overhead, compared to the typical channel estimations that require a large number of training signals. Through the simulations, we verify that, because of its low training overhead, the proposed estimation technique can provide a higher effective spectral efficiency than that of existing channel estimation methods requiring high training overhead.


A video recording study was carried out to investigate the dissolution of alumina in molten cryclite which is important in aluminium production. The dissolution characteristics and solubility of various kinds of alumina from different producing sources were compared. It was found that there are three stages in the dissolution procedure:formation of bath/alumina agglomerates on the bath surface,collapse of the agglomerates and dissolution,and settling down of fine particles of alumina and dissolution in the bath bulk,alumina dissolution at the cell bottom. Formation of bath/alumina agglomerates is beneficial to the electrolysis performance because it can prevent the formation of alumina sludge. Dissolution performance of sandy alumina is better than intermediate alumina according to the floating time of agglomerates and the complete dissolution time.

Relativistic nonideal fluid dynamics is formulated in $3+1$ space-time dimensions. The equations governing dissipative relativistic hydrodynamics are given in terms of the time and three-space quantities which correspond to those familiar from nonrelativistic physics. Dissipation is accounted for by applying the causal theory of relativistic dissipative fluid dynamics. As a special case, we consider a fluid without viscous/heat couplings in the causal system of transport/relaxation equations. For the study of physical systems, we consider pure ($1+1$)-dimensional expansion in planar geometry, ($1+1$)-dimensional spherically symmetric (fireball) expansion, ($1+1$)-dimensional cylindrically symmetric expansion, and a ($2+1$)-dimensional expansion with cylindrical symmetry in the transverse plane (firebarrel expansion). The transport/relaxation equations are given in terms of the spatial components of the dissipative fluxes, since these are not independent. The choice for the independent components is analogous to the nonrelativistic equations.


A novel approach to develop a digital phase shifter based on two-layer substrate integrated waveguide with the capability of electronic control is proposed in this paper. The phase shifter exhibits the properties of low insertion loss, wide relative bandwidth and good amplitude/phase imbalance performance. Wideband coupling technique with a transverse slot is used to guarantee the wideband performance. Electronic control is achieved by utilizing PIN diodes on transverse slots. Moreover, a simple equivalent circuit and analysis method is explained. The results of fabricated prototype agree well with the simulation. A phase shift of 90° with ≤ 1.5 dB insertion loss and 36% relative bandwidth (9 GHz to 13 GHz) is achieved for 15 dB return loss. Amplitude and phase imbalance is measured to be ±0.4 dB ±4°, respectively.


Histamine is the primary mediator involved in the pathogenesis of allergic rhinitis and chronic idiopathic urticaria. Platelet-activating factor (PAF) is also a mediator which plays a key role in the allergic reaction. Rupatadine is a novel antihistamine of the second generation approved recently in Europe for the treatment of allergic rhinitis and chronic idiopathic urticaria in patients aged ≥ 12 years. Rupatadine shows both antihistamine and anti-PAF effects because it presents hybrid molecule. One unit of this molecule has high affinity to H1 receptor, and the second one blocks the receptor for PAF. Relative potency of rupatadine is much higher than that of other second generation antihistamines. Rupatadine also has anti-allergic and anti-inflammatory activity. The drug blocked the release of histamine from mast cells and other proinflammatory cytokines such as IL-5, IL-6, IL-8, TNF-α and GM-CSF from activating human lymphocytes. It also blocked in vitro chemotaxis of human eosinophils to eotaxin, and neutrophils to PAF and LTB4. Anti-allergic and anti-inflammatory activity of rupatadine results from blocking NFκβ. Clinical trials have indicated that rupatadine is significantly more effective than placebo and equally effective as other antihistamines of the second generation. Rupatadine is well tolerated, and side effects are mild and moderate, the most common ones were headache and somnolence. The drug is safe, not cardiotoxic, does not impair psychomotor or cognitive activity.

In 1993, 2.4 million students entered college; of those, some 1.1 million will leave without a degree (Tinto, 1993). This is not a new trend. Data from the American College Testing Program show that the first-year attrition rate for all students in four-year public universities has remained largely unchanged over the last decade. In 1983, this rate was 29.1%; in 1992 it was 28.3% (Tinto, 1993). The other end of the undergraduate time-scale looks equally distressing. In 1983, the graduation rate at the same institutions was 52.6% while in 1992 it had declined to 46.7%. The phenomenon of college attrition is even more exaggerated among certain underrepresented minority groups. Hispanics graduated at a rate of only 35%, and African [End Page 55] Americans at a rate of only 45% (Brower, 1992), far below the rates for White students (Tinto, 1993).


This study identified the glycemic index (GI) of two different commercially available varieties of potatoes, Lady Rosetta (LR) and Spunta (S), cultivated under organic fertilization conditions and fried in extra virgin olive oil. Eight healthy males 26 ± 1.5 years of age, 84.7 ± 3.2 Kg body mass and 19.2 ± 1.5% of body fat participated (mean ± SE). Volunteers consumed in a random order 50 g of anhydrous glucose in 300 ml of water (G), or 50 g of available carbohydrate of sliced and fried LR or S twice. Blood glucose was measured enzymatically from capillary blood samples before food consumption and at 15, 30, 45, 60, 90 and 120 min postprandially. Each meal was prepared and consumed in the morning after a 12-hour overnight fast, whereas diet and physical activity were controlled. For the calculation of GI the mean blood glucose values of the two trials (i.e. 1st and 2nd time) in each potato variety (i.e. LR or S) were considered. The incremental area under the blood glucose-time curve (IAUC) was used according to trapezoidal rule for the determination of GI. The IAUC was 5504 ± 1173 mg.min/dl and 4012 ± 911 mg.min/dl whereas the GI was 114 ± 15 and 83 ± 12 in LR and S respectively. However, these differences were not significant (IAUC: p= 0.21 and GI: p=0.20). Fried potato slices in extra virgin olive oil derived from LR and S potato varieties cultivated under organic fertilization conditions possess similar GI in healthy male volunteers. key words: glycemic Index, French Fries, Biological, Fertilization.


In this study the numerical simulation of three dimensional turbulent impinging round jets are conducted using the CFD method. The two jets one impinging on a simple flat plate and the other impinging on a circular pedestal heated and mounted on a flat plate are investigated. The flow fields and heat transfer characteristics of the two cases are compared at a Reynolds number of 23000 and nozzle to target distance of six times the diameter of the jet. The purpose of this paper is studying the effect of existence of the pedestal on rate of heat transfer. Turbulent fluctuations in the velocity field are modeled using the Reynolds Averaged Navier-Stokes (RANS) methodology. Turbulence is assumed to be isotropic. The buoyancy and radiation heat transfer effects are neglected and the flow is considered to be incompressible. The simulations are performed using various turbulence models such as the Realizable   k ,   k RNG ,   k SST and f  2  . There is a good agreement between the convective heat transfer results of the f  2  model and experimental data. The results show that existence of pedestal increases the heat transfer coefficients and causes a local minimum in the heat transfer coefficient profile on the symmetry axis, which is in contrast to the results of the simple flat plate.


A brief review of the current status of marine and offshore safety regulations in the UK is outlined. Several issues pertaining to the problems encountered in applying the existing reliability and safety analysis methods in quantitative safety appraisal studies, especially in the early concept design stage of marine and offshore engineering products, are discussed. In this paper, four novel risk assessment and decision support frameworks are presented. These include a design trade-off approach using the Taguchi method, a safety-based decision support system based on artificial neural network techniques, a fuzzy-logic-based synthesis incorporating the Dempster-Shafer approach for multiple attribute decision-making, and an integration of approximate reasoning approach and evidential reasoning method for design evaluation. Four illustrative examples are used to demonstrate the novel tools, together with the discussion on the conditions under which each approach may be applied effectively. Finally, recommendations on further development in subjective safety modelling, decisionmaking techniques and their integration into a safety management system are suggested.


Bedaquiline, a diarylquinoline, improved cure rates when added to a multidrug-resistant tuberculosis (MDR-TB) treatment regimen in a previous placebo-controlled, phase 2 trial (TMC207-C208; NCT00449644). The current phase 2, multicenter, open-label, single-arm trial (TMC207-C209; NCT00910871) reported here was conducted to confirm the safety and efficacy of bedaquiline. Newly diagnosed or previously treated patients with MDR-TB (including pre-extensively drug-resistant (pre-XDR)-TB or extensively drug-resistant (XDR)-TB) received bedaquiline for 24 weeks with a background regimen of anti-TB drugs continued according to National TB Programme treatment guidelines. Patients were assessed during and up to 120 weeks after starting bedaquiline. Of 233 enrolled patients, 63.5% had MDR-TB, 18.9% had pre-XDR-TB and 16.3% had XDR-TB, with 87.1% having taken second-line drugs prior to enrolment. 16 patients (6.9%) died. 20 patients (8.6%) discontinued before week 24, most commonly due to adverse events or MDR-TB-related events. Adverse events were generally those commonly associated with MDR-TB treatment. In the efficacy population (n=205), culture conversion (missing outcome classified as failure) was 72.2% at 120 weeks, and 73.1%, 70.5% and 62.2% in MDR-TB, pre-XDR-TB and XDR-TB patients, respectively. Addition of bedaquiline to a background regimen was well tolerated and led to good outcomes in this clinically relevant patient cohort with MDR-TB.

A two-zone control-oriented charge mixing model is developed to describe charge mixing with thermodynamic interaction between fresh charge and residual gas during the intake stroke. This work enables operating range of homogeneous charge compression ignition (HCCI) to be extended without loss of stability. Cylinder volume is divided into two zones with a fictitious divider. In the mixed zone, fresh charge and residual gas expelled from the unmixed zone are mixed homogeneously. Otherwise, the unmixed zone contains rest of the residual gas burned in the previous cycle and trapped by early close of exhaust valves. Incoming fresh charge with high speed expels some of residual gas from the unmixed zone to the mixed zone by force. In this perspective, mass transfer represents charge mixing between two zones. For model validation, optical engine test is carried out. Optical access to the engines with an infrared (IR) camera allows graphical analysis to estimate thermodynamic states of two zones.

We report magnetic susceptibility, resistivity and optical spectroscopy study on single crystal sample DySb. It exhibits extremely large magnetoresistance (XMR), and a magnetic phase transition from paramagnetic (PM) to antiferromagnetic (AFM) state at about 10 K. A 'screened' plasma edge at about 4000 cm−1 is revealed by optical measurement, which suggests that the material has a low carrier density. With decreasing temperature, the 'screened' plasma edge shows a blue shift, possibly due to a decrease of the effective mass of carriers. Notably, an anomalous temperature dependent midinfrared absorption feature is observed in the vicinity of the 'screened' plasma edge. In addition, it can be connected to the inflection point in the real part of the dielectric function , the frequency of which exactly tracks the temperature dependent 'screened' plasma frequency. This phenomena can be explained by the appearance of a coupled electron–plasmon 'plasmaron' feature.


The invention discloses an in-vivo conveying protective device for a medicine carrying apparatus. The in-vivo conveying protective device comprises a handle, a near-end part and a far-end part. The handle is connected with the near-end part; the near-end part is connected with the far-end part; a cavity is formed in the handle; the near-end part is of a hollow structure which communicates with the cavity of the handle; an elastic bag is disposed inside the far-end part and communicates with the hollow structure of the near-end part; and moreover, the elastic bag can contract outwards and expand and protrude inwards. As the medicine carrying apparatus is limited and fixed in the far-end part through the elastic bag when being carried and conveyed in vivo through the protective device, medicine falling off, apparatus drop and scratch damage to the blood vessel walls are avoided, the surgical risk is reduced remarkably, the treatment effect is guaranteed, and the surgical successful rate is increased. Besides, the in-vivo conveying protective device for the medicine carrying apparatus is simple in structure, convenient to operate and extremely high in practical value.


With the basic α-attractor potentials, we investigate an inflationary regime in the high-k limit, where the cosmological perturbation breaks down due to large enhancement in the scalar power spectrum and generation of large negative values of the Bardeen potential. We analyze that, this deep sub-horizon regime creates a situation, which is congenial to the formation of the primordial black holes (PBHs). We work in the spatially flat gauge with δφ 6= 0 and thus explicitly show the roles of perturbations in the inflaton field as well as in the background gravitational field in the mentioned enhancements and thereby in the PBH formation. We calculate the values of σ(M), β(M) and fPBH(M) around the peaks in the density contrast profile and thus estimate the fraction of PBH in the dark matter of the present universe, corresponding to certain mass scales. We observe the formation of PBHs in the k range 0.43×1013 Mpc−1 to 9.8×1013 Mpc−1 with masses 1.35×10−13M to 2.60×10−16M , evaporation times 7.74× 1033 sec to 5.53× 1025 sec, Hawking temperatures 3.72× 10−8 GeV to 1.93× 10−5 GeV and fPBH(M) ∼ 6.12× 10−6 to 3.63× 10−1. The calculated mass range lies in the regions of forecasts by LISA, WD, NS, DECIGO/AI, FL, SIGWs and the fPBH(M) results overlap with those of DECIGO/AI, FL, SIGWs. ar X iv :2 11 2. 05 40 8v 2 [ gr -q c] 6 M ar 2 02 2

[Objective] The objective of the present study was to study the genetic effects of polymorphisms of HinfⅠ, AluⅠ and PstⅠ loci within POU1F1 gene exon 6 on Jianxian Red cattle growth traits. [Method] POU1F1 gene exon 6 polymorphic fragments were detected by PCR-RFLP technique using 144 Jianxian Red cattle. Association analysis of POU1F1 gene exon 6 polymorphism with growth traits was also conducted. [Result] The results showed that 451 bp PCR products digested with HinfⅠ demonstrated polymorphisms. Moreover, the frequencies of allele AA, AB and BB genotype of Jiaxian red cattle were 0.1875, 0.3056 and 0.5069, accordingly, the frequencies of allele A and B were 0.340 3 and 0.659 7 respectively. The homozygositiy, heterozytosiy, the effective allele numbers, and PIC value of POU1F1 gene exon 6 HinfⅠ locus were 0.5510, 0.4490, 1.8148 and 0.3482 respectively. As this locus belonged to the middle polymorphic index, it was suggested to be an effective evaluation parameter for studying genetic resource However,no polymorphism was found at POU1F1 gene exon 6 AluⅠ and Pst I loci. The correlation of HinfⅠ polymorphisms of POU1F1 gene exon 6 and growth traits was analyzed and the result showed that there was significant relationship between Hinf I polymorphism and body length (P<0.05). The individual with genotype BB had longer body length than the individual with genotype AB and AA, suggesting the allele B had significant effect on body length of Jianxian red cattle. [Conclusion] The genotype BB was significantly correlated with the fine performance and the selection of the allele B was better for the improvement.


Objective To investigate the high-sensitivity C-reactive protein(hs-CRP), homocysteine(Hcy) and Interleukin-6(IL-6) expression in patients with acute cerebral infarction. Methods From January 2011 to October 2013, 79 cases of acute cerebral infarction patients in our hospital were enrolled in our study. 85 cases of healthy people were collected as control. Hcy, hs-CRP and IL-6 were tested before and after treatment. Results Compared with the control, Hcy, hs-CRP and IL-6 were higher when admission(P 0.01), 1 day of hospitalization, compared with admission, Hcy, hs-CRP and IL-6 were significantly higher(P 0.05). After 4 days' treatment, Hcy, hs-CRP and IL-6 were decreased(P 0.05). After 9 days' treatment, Hcy, hs-CRP and IL-6 were decreased to normal. Hcy and hs-CRP, Hcy and IL-6, Hcy and IL-6 were positively correlated(P 0.01). During treatment, seven cases of patients died. Compared with pro-treatment, after 9 days' treatment, NIHSS score was significantly lower(26.4±3.9 vs 15.2±4.2,P 0.05). Conclusion The hs-CRP, Hcy and IL-6 have important reference value in diagnosis and treatment of acute cerebral infarction.


Abstract Mathematical Literacy deals primarily with the insertion of a mathematical gaze on extra-mathematical issues and situations. These issues and situations are to a large extent determined by curriculum, learning resource and test designers. The issues and contexts learners prefer for mathematical investigation is a largely under-researched area. In order to ascertain contexts that learners would find interesting to deal with in Mathematical Literacy a study, the Relevance Of School Mathematics Education (ROSME), was embarked upon. Some of the findings of this study and how they relate to current issues in South Africa are presented in this paper. It is concluded that within their Mathematics Literacy experiences learners should also be confronted with issues and situations to which they accord priority. However, this should be done with circumspection given that schools are also places where interests are to be developed. This, in turn, calls for a curriculum where the interests of learners and those fixed by curriculum, learning resource and test designers are balanced.


Objective To evaluate the effects of mycophenolate acid (MPA),the active metabolite of MMF in vivo,on immun function and NF-κB expression of murine bone marrow-derived dendritic cells (DCs). Methods Cultured DCs were treated with MPA at doses of 0.01and 0.1μmol/L. The antigen presentation and allostimulatory activities of the DCs on allogeneic T cells were tested by 3H-TdR incorporation and mixed lymphocyte reaction respectively. The expression of NF-κB p50 in DCs was measured with Western blot. Results DCs cultured in the presence of MPA exhibited weaker activity of stimulating the proliferation of allogeneic T cells and antigen presenting function. The protein expression of NF-κB p50 was found decreased in DCs treated with MPA in a dose-dependent manner. Conclusion MPA exerts a negative effect on immune function of cultured DCs in vitro,which is associated with a decreased NF-κB activity.


A method for the FDTD analysis of quasi-optical MESFET arrays is presented in this paper. To analyze active devices such as MESFETs, this method creates a set of field-state central finite difference equations; and all the field and state variables are solved simultaneously at the same FDTD time step. It will be shown in this paper that this formulation is simple and straightforward. The analysis of quasi-optical MESFET oscillator arrays have been performed to show the application of this method. Excellent agreements have been obtained between the results from this simulation method, from commercial softwares, and from experimental measurements to show the validity of this method.


AbstractRadiofrequency endometrial ablation is a frequently used treatment for refractory menorrhagia. Reported complications have been relatively uncommon. We report 2 patients with bacteremia complicating radiofrequency endometrial ablation; one a polymicrobial bacteremia due to nutritionally deficient Streptococcus (Granulicatella adiacens) and an anaerobic Gram-negative bacillus not further identifiable and the other bacteremia due to Streptococcus agalactiae. Bacteremia complicating endometrial ablation of any type is rarely reported in the literature. We herein report these 2 cases and review the literature on endometrial ablation and bacteremia. There are no current guidelines for the administration of antimicrobial prophylaxis for endometrial ablation.


The second chapter analyzes the Perrault family strategy up to about 1660. Initially, the Perraults had no connections to literary life, and they were involved in legal professions. However, the status of lawyers was declining in the last years of the sixteenth century and early years of the seventeenth century, and the careers of the couple's sons represented attempts to diversify the family's educational and professional investments. Most significantly, Pierre II developed a career in the monarchy's financial administration, built on the venality of office. Responding to the monarchy's thirst for cash, financiers like Pierre played a high-stake game: while they could go bankrupt, they also stood to make immense profits from loans to the monarchy and from tax collecting. Thus this chapter demonstrates the importance of "court capitalism" and office-holding to the first literary endeavors of the family.


In order to shorten the manufacturing period,decrease the manufacturing cost and improve the manufacturing process of high-speed vehicle,stretching experiments of high strength aluminum alloy plates of ten types used in high-speed vehicle were done with the multi-test machine controlled by computer.Based on the mechanical property parameters and stress and strain relationship gotten by the stretching experiment,finite element simulations of punching aluminum alloy plates of ten types were made with finite element method according to "Performance Testing and Forming Method og Sheet Metal"regulated by the national standard of China.The limit bending radius and the limit bending angles of ten materials were gotten under thirty cases and the analysis results were used to guide the punching test of high strength aluminum alloy and to optimize the test cases.Therefore,the numbers of punching test cases are reduced.The cases of the test can be minimized to get the basic bending property parameters


Three recent European performance assessments involving national HLW disposal management programmes offered the opportunity to compare sorption databases for similar crystalline rock-water and bentonite-porewater systems. An additional sorption database for a granitic rock-water system is available for comparison, from the Canadian radioactive waste management programme. The basis for deriving each database is discussed together with the results from this comparison exercise. In general, the agreement between corresponding databases is good, although there are limited or no experimental sorption data for a few elements, notably Pd, Sn, and for reduced forms of Tc and the actinides U and Np.

—The present study reports on the natural history of the Ningshan Lined Snake (Stichophanes ningshaanensis) in the Shennongjia National Nature Reserve (NNR) in western Hubei Province, China. Prior to this work, little was known about the natural history of this species due to a paucity of specimens since the original description in 1983. Since its discovery, only the original three specimens were known to science, all of which are now lost or destroyed. Over the course of five summers, we observed 24 specimens within the Shennongjia NNR. We report on its natural history, including seasonal activity, habitat and environmental preferences, breeding behavior, sexual dimorphism, and incubation data for the eggs. We reiterate the morphological differences between Stichophanes, its former genus Oligodon, and members of Pareatidae. In China, Stichophanes is not protected under law due to the species being classified as "Data Deficient." The species exhibits sexual dimorphism and dichromatism, i.e., males are smaller than females and the sexes differ in color. The species has unique breeding habits in mid-summer, and copulation occurs immediately after oviposition of the females. The number of eggs per clutch ranges from eight to nine, and takes 64 days to hatch.


Multi‐layers of surface materials were investigated for the isolation of floor impact sounds in concrete structures. Both resilient and viscoelastic damping materials were tested according to the modified method of ANSI S2.22 for calculating elastic modulus and loss factor. The dynamic characteristics of the concrete structures subjected to heavy‐weight floor impacts were modeled by the compressional damping theory, using sandwiched beams. Results show that the viscoelastic damping materials are more effective than the resilient materials. In field measurements, the insertion loss of the heavy‐weight impact sounds, which was mainly affected by the modal characteristics at low frequencies, was higher in floor structures with the damping materials.


Obesity is a well‐known risk factor for the development and severity of acute pancreatitis (AP), but the relationship between the abdominal visceral fat area (VFA) and mortality is unclear. We evaluated the effect of the VFA on mortality in severe AP (SAP).


Diets of the rock trout, Agrammus agrammus, in the shore area of Tongbaeksom, Pusan over the period of July 1981 to June 1982 were studied. Specimens were sampled by angling. Stomach analysis showed that the rock trout fed mainly on epibenthic food in the littoral zone along the coast of Tongbaeksom. The food organisms of the enviornment were studied by means of underwater sampling around the angling area for this study. Although the food items of the fish changed slightly with season and age-group, main food items were Amphipoda (Gammaridae, Caprellidae) and Isopoda (Sphaeromidae, Idotheidae). This suggests that the diets of A. agrammus mainly comprised epibenthic food. Food diversity increased with age. The fish almost consummed on smaller food in size, but had selective predation according to food size, i. e. on larger food as age increases. These data provide additional support for the importance of the detritus-benthos-consummer type food chain.

The exceeded consumption of fossil fuels has already brought several problems for humanity, besides not being a renewable fuel, it brings several environmental damages. In this context, electricity appear as a potential substitute, especially for motor-based vehicles. Therefore, the purpose of this work is to present a brief history of electric cars and how they are being improved over the years. In addition, to introduce the concept of wireless power, developed by Tesla, which proposes that electric cars can be loaded in motion, reducing considerably the batteries weight, once the energy storage may be less if the vehicle recharge while moving. Finally, the main objective of this work is to analyze and optimize some coil models through the inductance and resistance equations, in order to obtain an ideal model for electric vehicle coils.


In popular discourse stereotypes about the opera and its audience abound. The prototypical operagoer is the well-dressed businessman in his fifties from the upper middle-class for whom conspicuous leisure is as important as the aesthetic pleasure derived from attendance. Or it is the elderly woman, ostentatiously dressed en robe wearing a stylish fur coat and giving herself to refined chit-chat on the mise-en-scene or the vocal qualities of the prima donna. Question remains whether these obstinate images still hold for the present day opera audience—and/or whether they have ever been pertinent/applicable. Is opera indeed exclusively the pastime of the well-to-do bourgeoisie, rich in both economic and cultural capital? Or can other, more ascetic-elitist audience segments be traced (Bourdieu, 1979)? Based on a large-scale visitor study in the Flanders Opera in Ghent and Antwerp (Belgium), we focus on the social composition of the contemporary opera audience in Flanders, its attitudes with regard to cultural and economic left-right axes and its aesthetic dispositions. Specific multiple correspondence analysis and Euclidean classification (Le Roux and Rouanet, 2004) are used to explore the audience's cultural, economic and aesthetic values/attitudes and to analyze in what way these are linked up with social background characteristics.


Oocyte-cumulus cells connected to some of the parietal granulosa cells (OCG complexes) were mechanically obtained from pig early antral follicles 0.5-0.7 mm in diameter and were cultured for 8 days in collagen gels. The effects of FSH, dbcAMP, estradiol-17β (E2) and EGF on antrum formation in the OCG complexes were studied. After 1 day of culture, every OCG complex formed a spherical compact structure. The OCG complexes which had undergone FSH and dbcAMP treatment then formed antra, resulting in antral follicle-like structures, but no antra were formed in the E2, EGF-treated and control groups. Instead, in these groups the granulosa cells spread away from the oocytes. Proteins similar to those in pig follicular fluid were accumulated in the antral follicle-like structures of the OCG complexes induced by FSH and dbcAMP stimulation. These results indicate that mediated by cAMP rather than estrogen, FSH induces antrum formation in pig granulosa cells, and that EGF itself does not induce antrum formation in vitro.


In the legal literature there are enough publications on the competence of local self-government, nevertheless this topic attracts attention of not only representatives of the legal science, but also economists and practitioners. Special interest to this institution of municipal law is connected with the controversial aspects relating not only to the very concept of the competence of the municipal formation, but also to the issues of its essence, nature, the distribution of powers between individual units of local government bodies and state authorities and government. These concepts have found some consolidation in the current Russian legislation both at the federal and regional levels, but this did not solve all the problems that arise in the process of exercising the powers available to municipal entities.
The essence of the definition of the concept of the competence of local self-government and its correct use in law-making activities is of great importance for the regulation of the functions of local selfgovernment bodies, improving law-making technology, enhancing the role of normative acts, which will naturally affect the effectiveness of local self-government. In this article, an attempt is made to investigate the essence of the concept of the competence of local self-government as an institution of municipal law within the framework of the implementation of public authority, not only by the relevant bodies, but also by the population.
Key words: local self-government, competence, powers, subjects of reference, local self-government bodies, municipalities.

Based on the semiconductor fundamentals and using the band‐gap‐narrowing (BGN) models widely quoted in the literature, a thorough analysis of the effective intrinsic concentration nie dependence on impurity concentration in degenerately doped n+‐ and p+‐silicon is performed. It is shown explicitly that starting from a threshold level of dopant concentration the Fermi–Dirac statistics, associated with the semiconductor degeneracy, gradually cancels the impact of BGN on the (pn) product in both highly doped n+‐and p+‐silicon, regardless of the BGN model employed. Depending on the magnitude of and uncertainties related to the prevailing BGN models, the results of this work show that the effective intrinsic density nie drops to the value of ni at doping levels of 1020–1021 cm−3 in both types of silicon materials. The main qualitative implications and quantitative consequences of the presented results for bipolar device physics and models are also outlined.

We present a novel approach to improve self-referenced sensing based on multipleresonance nanorod structures. The method employs the maximum likelihood estimation (MLE) alongside a linear response model (LM), relating the sensor response (shifts in resonance wavelengths) to the changes due to surface binding and bulk refractive index. We also provide a solution to avoid repetitive simulations, that have been previously needed to determine the adlayer thickness sensitivity when measuring biological samples of different refractive indices. The finite element method (FEM) was used to model the nanorod structure, and the nanoimprint lithography was employed to fabricate them. The standard deviation of the results based on the MLE method is lower than that associated with the LM results. The method can be applied to an extended number of resonances to achieve a higher accuracy and precision. © 2017 Optical Society of America OCIS codes: (120.3890) Medical optics instrumentation;(130.6010) Sensors; (170.4520) Optical confinement and manipulation; (280.1415) Biological sensing and sensors; (280.4788) Optical sensing and sensors; (240.6680) Surface plasmons; (350.4238) Nanophotonics and photonic crystals.

We introduce a basic model for human mobility that accounts for the different dynamics arising from individuals embarking on short trips (and returning to their home locations) and individuals relocating to a new home. The two modes of motion occur on widely separated time scales and affect different phenomena: for example, short trips, constituting the bulk of human motion, dominate the spread of diseases, while the spread of genes or family names is more strongly affected by relocations. In many everyday life situations the two modes of motion need to be considered simultaneously. This is illustrated by a simple SIR model for epidemic spreading where trips and relocations lead to dramatic differences even under equal volumes of travel.

The remote controller includes control elements capable of vertically moving, horizontally moving or axially moving. When the control elements move in a perpendicular direction, horizontal direction or axial direction, the remote controller is used to transmit the signals for controlling the television set; the television set is used to receive signals generated from the remote controller and realize its corresponding function according to the signals.


The after thermic cleaning magnetic remanence directions of twelve hand samples collected at different stratigraphic positions from the Itarare Subgroup (Tubarao Group) exposures at the Mococa area give a paleomagnetic pole at 57o South, 357° East, α 95 = 15°. The position of this pole is close to other South American paleomagnetic poles assigned to the Upper Carboniferous suggesting an equivalent age for the Itarare redbeds from Mococa. The cleaned magnetic remanences of seventeen hand samples collected at different stratigraphic positions of the Corumbatai Formation exposures (Passa Dois Group) in the Artemis-Piracicaba area define three reversals of the geomagnetic field. On the basis of the geological data and the present knowledge about the Late Paleozoic Interval of Reversed Geomagnetic Polarity, those changes of polarity are interpreted as evidence of an Upper Tartarian age for the Corumbatai redbeds from the Artemis-Piracicaba area. On the assumption of a geocentric dipole the paleomagnetic pole for the Corumbatai redbeds is calculated at 86° South, 294° East, α 95 = 14°. This pole would define a "time group" with the other Middle and Upper Permian paleomagnetic poles for South America.


The active carbon with high specific surface area is prepared by activating the carbonized rice husks by using KOH as the activation agent.The effects of such factors as the ratio of activation agent to rice husks,the activation temperature and time upon the adsorption properties of active carbon are investigated.The optimum preparation conditions are determined as follows:the ratio of the activation agent to rice husks being 3∶1,activation temperature and time being 800℃ and 1h,respectively.The iodine adsorption value and methylene blue adsorption value are 1520.32mg/g and 3442.50mg/g respectively.The specific surface area of the prepared active carbon is 2027.42m2/g.The morphology and structure of active carbon are observed by SEM and X-ray.The carbonization and activation process together produce porous structure.


We apply integrated attribute analysis to extract more reliable quantitative information from processed GPR data, and obtain a better characterization of subsurface structures. A multi-attribute approach is used to characterize the subsurface through different attribute categories, including instantaneous, coherency, and textural attributes applied to quantities related not only to amplitude, phase, and frequency, but also to other parameters calculated from the original data. The different attributes can be integrated into a single view with composite displays (overlays and mixed displays). The proposed procedure is tested in different environments namely: archaeological areas to characterize cultural heritage buried in highly heterogeneous subsurface environments, and glaciers to image their inner structure and to monitor the seasonal changes of firn layers. The results from two case studies demonstrate that the proposed integrated attribute analysis can highlight zones characterized by different electromagnetic parameters, better visualize and quantify GPR features in an automatic and objective manner, and enhance GPR data interpretation in different application fields.

This paper proposes a novel method for license plate(LP) detection from images with complex background. First, it segments images with an adaptive binarization method to avoid the problem that nonuniform illumination creates, and some undesired image areas are removed by limiting the range of region properties of connected components(CCs). Secondly, CC analysis is used to construct nearest neighbor chain(NNC) for detection of candidate LP regions(LP-NNC). The average height and direction of each LP-NNC is estimated to deal with images acquired from different view or distances. Thirdly, two variable-length square templates are designed to match horizontal and vertical projections of LP image gradients. They are combined to verify all candidate LP regions, and the most possible region is selected as the true LP region. Experiment results on various types of LP images show that this proposed method has achieved desired detection result for complex scenes.


Continuous flow analysis (CFA) has become a popular measuring technique for obtaining high-resolution chemical ice core records due to an attractive combination of measuring speed and resolution. However, when analyzing the deeper sections of ice cores or cores from low-accumulation areas, there is still need for further improvement of the resolution. Here a method for resolution enhancement of CFA data is presented. It is demonstrated that it is possible to improve the resolution of CFA data by restoring some of the detail that was lost in the measuring process, thus improving the usefulness of the data for high-resolution studies such as annual layer counting. The presented method uses deconvolution techniques and is robust to the presence of noise in the measurements. If integrated into the data processing, it requires no additional data collection. The method is applied to selected ice core data sequences from Greenland and Antarctica, and the results demonstrate that the data quality can be significantly improved.

SYNOPSIS. Paramecium multimicronucleatum was exposed to various external concentrations of adenosine triphosphate (Na2ATP) to determine the effects thereof on the cycling rate of the nephridial apparatus. Normal rate was found to vary from 3.46 to 4.28 cycles/min with a mean rate of 3.85 cycles/min at 20 C. Concentrations of ATP of less than 5 × 10−4 M caused only slight, very temporary acceleration of the cycling rate. At 5 × 10−4 M the cycling rate was accelerated less than 15%. At 3 × 10−3 M cycling rate was accelerated, varying from 5.35 to 7.24 cycles/min, with a mean accelerated rate of 6.25 cycles/min, a mean aoceleration of 88.3%. Changes in rate after addition of 5 × 10−3 M ATP ranged from a decrease of 6.2% to an increase of 1.8%, with the nephridial apparatus ultimately stopping. At higher concentrations, stoppage was almost immediate. Paramecium is rapidly dehydrated by the ATP-accelerated cycling of its nephridial apparatuses, with a net loss of 27% of its volume in 6 minutes in the 3 × 10−3 M ATP.


The slabs are reheated before being rolled,with the increasing of fuel prices and the applications of new steel grades,the establishment of accurate slab temperature-time heat transfer model becomes the primary condition for improving the product quality and saving the energy.In this paper,the slab heating process is simulated,a physical mathematical model for slabs heated in reheating furnace of walking beam type is established.The finite volume method is used for the discretization of mathematical mode.From the programming solution,some useful conclusions are obtained,the temperature of slab corner is the highest,the heating zone has the fastest heating rate with the maximum temperature difference,the uniform heating zone has the minimum temperature difference,and the time difference is bigger than target value,therefore the uniform heating time should be prolonged.


: Around 20% of adolescent suffer from a mental illness, and suicide is the third leading cause of death among this age group. An interesting but disturbing fact is mental illness onset surge in adolescents. This article dives into the neuroscience of why and how the adolescent brain is more vulnerable to mental health challenges. The article discusses the two major sensitive periods of brain development: infancy and adolescence, of which the latter will be discussed in the context of sex hormones, neurotransmitters, anatomical maturation, and error signals generated by the brain. The major take-away is that the adolescent brain is in a period of construction that makes it more challenging to make the right decisions in the right situations. It is emphasized how the adolescent brain does not choose to act irrationally or succumb to peer pressure. Rather, the adolescent brain is in a transition phase that requires time and support to mature. This article is the first in a two-part series on adolescent brain development and function. This article was first published in Subkiton April 05, 2022 (https://www.subkit.com/pernillebuelow/posts/the-vulnerability-and-strength-of-the-adolescent-brain).

The characteristic appearances of the fluid-filled uterus on computed tomography (CT) have been well described (Scott et al, 1981). In addition, the use of ultrasound in the diagnosis and elucidation of congenital anomalies of the female genital tract has been reported previously and classification systems have been proposed (Malini et al, 1984). Sonographic detection of such anomalies has been particularly successful during pregnancy and in neonates (Wilson et al, 1978; McArdle & Berezin, 1980). Experience with paediatric and adolescent patients has been less extensive (Haller et al, 1977). We present a case report of an adolescent girl with septate uterus and unilateral obstruction and its appearance on CT and ultrasound.


Abstract The 21st century provides a turning point from the days of exploitation of natural resources and of infrastructure construction to the proper management of national lands to establish human coexistence with the environment. This paper mainly discusses the issues for the improvement of engineering geological activities of research, education and the provision of information in the future at a World, Asian and Japanese level. The authors believe that some of the issues may be commonly observed world-wide and the solutions to the problems should be sought by the international cooperation of engineering geologists. Engineering geology needs to be an autonomous field of science and should provide educational systems to foster engineering geologists who can work together on an equal footing with professionals from other disciplines.


Measurement of serum immunoglobulin levels in 45 healthy Negro subjects and 52 healthy white subjects revealed significantly higher IgG and IgA levels in the Negroes. Serum immunoglobulin levels were determined in 73 Negro and 12 white patients with sarcoidosis. Levels of IgG and IgA were within normal range in all 12 white patients; IgM levels were increased in 3 patients. Among Negro patients with sarcoidosis, elevation of the IgG value was also infrequent, with mean levels significantly increased only in patients with chronic and stage 3 disease. Levels of IgA were significantly elevated in all types and stages of sarcoidosis, most markedly in those patients with chronic and advanced disease. Levels of IgM were frequently elevated, showing little relationship to stage or duration of disease. Two patients with sarcoidosis had no measurable IgA in their serum.


In Simultaneous Localization and Mapping (SLAM) algorithms, it is common to assume static environments. However, Static assumption may cause the SLAM system to drift or even crash in many practical scenarios where there are many moving objects. Combining SLAM with dynamic object estimation can significantly improve system stability in dynamic environments. In this paper, we propose a visual SLAM system for dynamic scenes that achieves precise, robust camera pose estimation and dynamic object tracking. By utilizing deep learning-based object detection and scene flow feature point tracking technologies, dynamic objects are separated from static ones. Then, dynamic and static objects arejointly optimized, resulting in 3D coordinates of feature points as well as the 6 degree-of-freedom state representation of dynamic objects in space. Through experiments, our proposed method has been shown to achieve higher accuracy and robustness in highly dynamic scenes.


With potted seedlings of Jatropha curcas as experimental materials,water saturation deficit,Relative permeability of plasma membrane and change of malondialdehyde content under different soil types(nutritional prescriptions).The results showed that seedlings could grow well at temperatures of 25℃ and 35℃ with different soil types,but when the temperature was 45℃ and with time prolongation at this higher temperature,the relative water content of leaves under the conditions of plasma membrane as well as well as the increase of malondialdehyde slowed down.Variance analysis showed the difference of physiological indices at high temperature between dry red soil and lateritic red soil and lateritic soil were extremely significant whereas the difference between lateritic red soil and lateritic soil was not.So the higher temperature resistance for the three soil types was in the sequence of dry red soil,lateritic red soil and lateritic soil.

Organic agriculture is the oldest form of agriculture and organic agribusiness is expanding fast worldwide. As green growth promoter it offers some solutions to the problems currently besetting the agricultural sector and sustainability. Organic farming has the sound potential to provide benefits in terms of promotion of green growth, mitigation & adaptation of climate war, environmental protection, conservation of non-renewable resources, improved f food quality and livelihood security. The research work focuses mainly on the integrated issues like economic security, livelihood security, food security green growth and sustainability. In most developing countries, agriculture continues to be the most important sector of the economy, accounting for the biggest proportion of employment (Båge, 2005). As such, unless effective strategies for agriculture development are successfully implemented, ending rural poverty will remain a distant goal. With regards to Organic agriculture contribution to improvements in livelihood security, food security, and environmental sustainability, the linkages are fairly well-defined and there is sufficient empirical and anecdotal data to support these. Organic agriculture contribution to improved profitability and therefore income, due to premium price and lower cost of production, is widely documented. Organic agriculture contribution to environmental sustainability is now a generally known fact and has been the main basis for subsidies program to support Organic agriculture in Overall, it is concluded that the unit cost of production is lower in organic farming.


It has been previously shown that an image with motion ghost artifacts can be decomposed into a ghost mask superimposed over a ghost‐free image. The present study demonstrates that the ghost components carry useful dynamic information and should not be discarded. Specifically, ghosts of different orders indicate the intensity and phase of the corresponding harmonics contained in the quasi‐periodically varying spin‐density distribution. A summation of the ghosts weighted by appropriate temporal phase factors can give a time‐dependent dynamic image that is a movie of the object motion. This dynamic image reconstruction technique does not necessarily require monitoring of the motion and thus is easy to implement and operate. It also has a shorter imaging time than point‐by‐point imaging of temporal variation, because the periodic motion is more efficiently sampled with a limited number of harmonics recorded in the motion ghosts. This technique was tested in both moving phantoms and volunteers. It is believed to be useful for dynamic imaging of time‐varying anatomic structures, such as in the cardiovascular system.


There are a variety of different noncontacting measurements that can typically be employed for developing modal test data. Digital image correlation, dynamic photogrammetry, and three dimensional (3D) laser vibrometry are all noncontacting measuring approaches that were used to obtain modal data for a candidate test structure along with traditional accelerometer measurements. Each approach has its benefits and drawbacks, so comparative measurements are made using these devices to show some of the strengths and weaknesses of each technique. Comparisons are made in all cases to a well-studied, finite-element model as well as to each other.


Although for many years pharmacies have been the sole distribution channel for food supplements and cosmetics, which are informally and without legal definition called dermocosmetics, they have now been introduced in department stores. Food supplements are concentrated sources of nutrients or other substances. They are used to supplement the standard diet and must be taken at a strictly prescribed dose. So-called dermocosmetics are the subject of recommendations for physicians, especially dermatologists in their patients and like other cosmetics, they have proven efficacy, maximum safety and cosmetic pleasure. The tool used was a questionnaire completed by 100 people. The findings indicate that the majority of consumers purchase both food supplements and cosmetics approximately once a month. Women spend more money than men. The first to influence them to buy cosmetics is the dermatologist and then the pharmacist. Consumers clearly prefer the pharmacy to the food supplements market and for cosmetics they are divided between the pharmacy and the department store, but they trust the pharmacist very much and for that reason they want to be in the department store in the respective department.


Abstract Under non-equilibrium conditions, the velocity distribution function of a gas differs from the Maxwellian equilibrium distribution. The effect of this deviation from equilibrium on the time correlation function and the spectral function associated with a Doppler broadened spectral line is calculated in full generality for stationary non-equilibrium processes. As special cases the heat conduction and the viscous flow in the hydrodynamic regime are discussed.


Delamination is a common damage in fibre reinforced composite laminates, usually hidden from external view, that can substantially reduce the structural stiffness which changes the dynamic response of the structures such as natural frequencies. Natural frequencies are the most reliable parameters for detecting damage while they do not directly provide information regarding its location and severity. To determine the location and severity of damage, it is necessary to solve the inverse problem using frequency shifts in multiple modes. In this paper, the graphical approach, which was previously employed for estimating two variables of crack (location and size) in isotropic beams, is extended in the current work to estimate the three variables of delamination (interface, span-wise location and size) in anisotropic composite beams from measured frequency shifts. Compared to the use of optimisation or neural network for detection, graphical technique is computationally inexpensive and quick since it solves the inverse problem without iterations or network training. The present approach has been validated using numerical simulation as well as experimental data from modal testing conducted on quasi-isotropic simply supported and cantilever beams. Results show that the proposed graphical technique can be used to assess the location and severity of delamination in composite beams with a high degree of accuracy.

ABSTRACT The phenomenon characterised by faster growth of the side of trees exposed to sunlight relative to the opposite side is termed plant phototropism. Vertical trunks of silicified wood occur in situ in the Hongliuxia area of Yumen City in north-western Gansu Province, China. A few trunks in the area exhibit well-preserved growth rings. Two petrified stumps reveal positive phototropism values of 279°–293° in the northwest direction. Living plants in Yumen City, Lanzhou City of Gansu Province and Beijing City showed positive phototropism values of 210°–255°±5° in the south-west direction. The evidence from wood phototropism supports clockwise rotation of the North China Block from previous palaeomagnetic studies since the Early Cretaceous. The petrified wood stumps in the Hongliuxia area of Yumen City are associated with 109 Ma strata corresponding to the main stage of the Yanshanian movement.


Objective: To compare the efficacy of paroxetine and amitriptyline in the treatment of primary fibromyalgia syndrome.Methods:46 out- and in-patients with primary fibromyalgia syndrome were randomized to two groups and treated respectively with amitriptyline 25mg~50mg per day and paroxetine 10mg~20mg per day. The Visual analogue scales(VAS) was used to evaluate the efficacy and adverse effects were recorded at baseline, month 1 and month 3.Results:In both groups pain was alleviated with statistical significance after 1 month of treatment. However the efficacy of amitriptyline and paroxetine was not statistically significant at different time points. The occurrence of adverse effects in paroxetine group was less than in amitriptyline group and the difference was statistically significant, especially dry mouth and palpitation.Conclusion:Paroxetine is as effective as amitriptyline in the treatment of primary fibromyalgia syndrome but with a better safety profile.

This book, by a former Executive Director of the NIV Translation Center and the general editor of The NIV Study Bible, is an apology for the New International Version. The NIV, Barker says, encompasses in a b~lanced way all the most important VIrtues of a good translation, making the ~IV the best contemporary English translation. More than that the NIV is worthy of adoption by , churches and denominations as their sole official Bible, to be used "for everything" (p. 98). Chapter One defines "balance" as the key to a good translation and summarizes the five main theses of the chapters to follow. First, a good translation will adopt a "balanced committee approach" (p. 13; chapter two). Second, it will rest on "a balanced textual basis" (p. 15), meaning it will rely on more than one manuscript tradition and use "accepted principles of text criticism" (p. 26; chapter three). Third, a good translation will adhere to "a balanced trans!ation philosophy" (p. 15) steermg a middle course between "formal equivalence" (matching the form and content of the original text) ~d."~ynamic translation" (providmg idiomatic clarity for the contemporary reader; chapter four). Fourth, a good translation will "use balance in handling difficult passages" (p. 15), by providing footnotes to reflect t~anslational options (chapter five). Finally, a good translation will be supported by "a wide range of balanced works" (p. 16), such as study Bibles, concordances, commentaries, encyclopedias, and electronic media (chapter six). A conclusion (chapter seven) summarizes the book and an appendix answers "miscella' neous questions" often asked about the NIV. All in all, Barker has provided a very readable, general defense of the NIV translation. The book deals with technical matters in a non-technical way and is well designed for use by non-specialists. Several aspects of Barker's apology for the NIV raise concerns for me. I will mention two. First, in lauding the "balanced committee approach" of the NIV, Barker claims that the translation process avoided "[e]cclesiastical, theological, and linguistic provincialisms" (p. 21), that participants like himself "gained a greater appreciation for the whole body of Christ" (emphasis original) (p. 21), and that the NIV does not purport to be "an 'evangelical' translation" but simply an "accurate" one (p. 17). These claims are disingenuous. Barker's own description of the history of the NIV shows that it was from beginning to end a translation by English-speaking evangelicals governed by a process that ensured the evangelical commitments of the translators. The process and product are therefore broad and balanced as far as English-speaking evangelicalism goes, but they are not


The cat-eyed snakes of the genus Madagascarophis are among the most commonly encountered snake species in Madagascar. Yet despite their broad distribution and frequent occurrence in human-disturbed habitat, Madagascarophis still contains unrecognized species diversity. Here, we describe a new species of Malagasy cat-eyed snake from a specimen found in the tsingy karst system of Ankarana in northern Madagascar. Using multiple loci from all currently described species, including the never-before-sequenced M. ocellatus, we delimit a new species and also determine its placement within the genus in a Bayesian coalescent framework, using BPP and *BEAST, respectively. Our results indicate that molecular data are sufficient to delimit this new taxon. These data also support its placement as the sister taxon to the recently described M. fuchsi which is endemic to the Montagne des Français karst massif also in northern Madagascar. We also provide a morphological description of this new snake species, which can be readily diagnosed based on external morphological characters, and include a species identification key for the entire genus based on external morphology.


One of the most studied functional foods in dog feed today is the prebiotic. Prebiotics are known for their modulating effects on the intestinal microbiota, fecal characteristics, and the immune system, which promotes beneficial effects to the host. However, with the diversity of prebiotics in the pet market, there are discussions around which prebiotics to use to stimulate these positive effects. In this case, the objective of this review was to demonstrate the main effects of different prebiotics on the feeding of healthy dogs. Platforms such as Embase, PubMed, and Mendeley were accessed to plot all scientific articles in vivo that reported prebiotics to feed adult or senior dogs. After excluding duplicate articles and without the evaluated criteria, we obtained a total of 36 articles. Our results demonstrated the diversity and concentrations of prebiotics in the feeding of healthy adult and senior dogs. The effects of prebiotics differ according to source, concentration, and length of the supplementation period. Several beneficial effects of different prebiotics have been observed in dogs, such as increased fecal Lactobacilli and Bifidobacteria concentrations and decreased fecal Clostridium perfringens and Escherichia coli concentrations, increased short chain fatty acids concentrations, decreased colonic ammonia absorption, and immunomodulatory effects, such as improved humoral immune response and increased phagocytic index. Galactooligosaccharides, fructooligosaccharides, mannanoligosaccharides, yeast cell wall, inulin, and beta-glucans were the most studied prebiotics, which showed potentially promising effects. This is a review that brings the importance and the modulating effects of prebiotics in the feeding of healthy dogs; the effects help the gastrointestinal tract and the immune system.


A study to determine the magnitude of thermal contact resistance at the base plate root of pin fin interface is presented. This is relevant to the performance of a heat sink/exchanger, if its fin and base plate is not made from one piece of metal. For instance, annular fins are usually fitted to tube, and thermal contact resistance does exist between the tube and the root of this fin. In this work, a 3 mm diameter and 60 mm height brass pin fins were adhesive bonded or brazed to an aluminium base plate. To determine the thermal contact resistance, the base plate was heated and temperatures at the root, middle and tip of the fins were recorded. Heat transfer coefficient for natural convection was evaluated using available correlations. Thermal contact resistance was calculated using the temperature difference and heat flow between fin's root and base plate. A finite difference heat transfer scheme was used to study the effect of heat transfer coefficient on the performance of fins. The thermal contact resistance for brazed fin was 28.5% less than the adhesive bonded fin. However, for the brazed and adhesive bonded pin fin, the differences in heat flow, fin efficiency and fin effectiveness was found to be 5%, 2 % and 2 times, respectively. The effect of thermal contact resistance on the performance of brazed and adhesive bonded fins is negligible if the heat transfer coefficient is less than 10 WmK. These findings are useful to assist the design of heat sink equipped with fin that operates in natural heat convection region.


Objective: To study the pathophysiological mechanism of arterial vascular remodeling in rabbits with hyperlipidaemia and chronic inflammation.Methods: The experimental rabbits were randomly divided into 4 groups. Normal control group, n=5, Hyperlipidaemia group, the animal received high fat diet, n=10, LPS group, the animal received LPS injection, n=10 and Hyperlipidaemia + LPS group, n=10. All animals were treated for 16 weeks. The arterial wall structure changes were observe by Masson stain method for tunica intima thickness(IT), media thickness(MT) and the ratio of IT/MT. The serum levels of HDL and LDL were examined. The serum levels of matrix metallo proteinase 9(MMP-9), tissue inhibiter of matrix metallo protinase(TIMP-1) and C-terminel telopeptide of type I collagen(CTX-1) were detected by ELISA. Results: Compared with the other 3 groups, Hyperlipidaemia + LPS group showed obviously thicker tunica intima, the inner elastic plate was interrupted or even disappeared, there were foam cells, lipid and inflammatory cells invasion, smooth muscle cell and collagen deposing under the intima. The media showed smooth muscle cell disorder and atrophy, the ratio of IT/MT increased. With 8 weeks treatment, Hyperlipidaemia and Hyperlipidaemia + LPS groups had significantly increased HDL and LDL. With 16 weeks treatment, Hyperlipidaemia + LPS group had obviously elevated MMP-9 and TIMP-1. Compared with Normal control group, LPS and Hyperlipidaemia + LPS groups had elevated CTX-1. All P0.05.Conclusion: Hyperlipidaemia and chronic inflammation might be the common pathogenic factors of atherosclerosis and vascular remodeling in experimental rabbits, the process could start and progress with their interaction.


Detecting heart diseases has been a research interest for centuries. Many of these approaches are based on heartbeat analysis using a stethoscope and some of these are digitally analyzed. In an ordinary system, doctors use an acoustic stethoscope to detect any aberration in the heartbeat and predict atypical conditions of the human heart. One major problem is that the frequency range and intensity of the heart sounds are flat as well as the sound may contain noise. Hence, even a cardiac specialist doctor may encounter difficulties to analyze the heart sound perfectly. This paper describes a new methodology to detect heart diseases by examining heart sounds in real-time. We consider the guts sound as our input data. Our methodology uses a deep learning approach to determine whether a patient has any disease or is healthy. To achieve that, we integrated an electronic stethoscope and a software solution known as a heartbeat audio classifier. Our proposed system solution should be able to differentiate normal heartbeats and heart murmurs with a prediction of probable heart problem type in real-time. We believe our approach assists in reducing the cardiac arrest rate.


In the operating state, the switchable bias current by the bias current is completely converted to differential amplifier biased. The system ON / OFF signals from the operating state transitions to the off state. The transition of the differential amplifier and disable the switchable bias current switching converter to reduce the bias current. The system ON / OFF signals from the power-off state transitions to the operating state, the differential amplifier is enabled, the switchable bias current and the bias current delay complete conversion to reduce the transition duration from the switching to. The differential amplifier is enabled to reduce the slew rate of reduction due to the bias current converter toward the reference voltage conversion. After reducing the duration of the conversion, switching the switchable bias current to said bias current complete conversion. Optionally, in response to the system ON / OFF signal transitions from the operating state to the power-off state is deactivated by adjusting the pass gate.

Integration of exogenous DNA into the yeast genome occurs by homologous recombination and is both directed and stimulated by the presence of double-strand breaks (DSBs) in transforming DNA. Repair of the break with or without plasmid integration occurs with equal probability and it is generally assumed that no information is lost or gained during this process. However, some important assumptions of current models are challenged by the results obtained by our group. First, we showed that rare illegitimate integrations may also occur in the presence of homology in the yeast genome and that integration in homology does not always result in reconstruction of the functional allele. Second, the presence of point mutations in double-stranded, but not in single-stranded plasmid, decreased integration in homology. However this antirecombinogenic effect was not proportional to the number of mutations. Third, targeted integrations were strongly suppressed by the presence of short heterologous sequences at the ends of the linearized plasmid. Terminal heterology is not always eliminated during integration and this process can lead to the generation of new alleles. In our experimental system, less then 10% of transformants that repaired DSB present on the replicative plasmid contained the plasmid sequence in their chromosomal DNA. We propose that the plasmid integration can be stimulated by repair processes operating on the hybrid DNA formed during recombination
