Abstract Recently, the presence of specific types of cut marks on large bovid bones from Klasies River Mouth has been linked to the butchering of desiccated carcasses acquired by scavenging. This paper presents data from bone assemblages produced by contemporary hunter-gatherers which show that identical marks can be produced when carcasses acquired by hunting and stiff from rigor mortis are butchered. These data suggest that such marks may be very common whenever there is an interval between when an animal is killed and butchered. Such delays may be common among societies that use simple hunting techniques.


Indonesia is currently faced with a plurality of religions, and of course, this plurality of religions is very vulnerable to conflict between religious communities.  One area that has a plurality in the religious field is Pembakulan Village.  Pembakulan Village is one of the villages that inhabits the Mount Meratus area which is very far away with modern civilization and adheres to several religions such as Christianity, Hinduism, Islam and one of them is the local religion, namely Kaharingan. Of course there are interesting which made them able to survive and live in harmony until now.  And one of the factors that create harmony is good communication and a high sense of tolerance. Therefore, the purpose of this research is to find out how the forms of communication and forms of tolerance between religious communities in Pembakulan Village are to create harmony. Based on the results of interviews and observations of researchers, this article argues that there are two forms of communication that create harmony in Pembakulan Village, Batang Alai Timur District, Hulu Sungai Tengah Regency, namely interpersonal and group and forms of tolerance, namely cooperation, mutual openness, freedom of religion and respect for religious activities.


Sikkim is one of th e hilly states in India where tea is cultivated. The developed as well as abandoned and ne glected tea plantations exist in the state. A survey of the abandoned and neglected tea plantations in the state revealed that the soil and weather parameters suit the requirements for tea cultivation , and such plantations could be revived by adopting th e rejuvenation technology package developed for tea gardens in hills at Institute of Himalayan Bioresource Technology which has been successfully implemented for development of such type of plantations in Abstract Alstroemeria is an important cut flower. It is mainly cultivated in Netherlands, Columbia, England and America. Alstroemeria is propagated through the division of rhizomes and once the virus infected material is propagated then the virus can transfer from one generation to the next. There are about ten viruses which infect Alstroemeria plants viz. Alstroemeria mosaic potyvirus, Alstroemeria streak potyvirus, Alstroemeria carlavirus, Cucumber mosaic cucumovirus, Tomato spotted wilt tospovirus/ Impatiens necrotic spot tospovirus, Alstroemeria ilarvirus , Tobacco rattle tobravirus, Arahis mosaic nepovirus, Freesia cucumber potyvirus and Rhabdovirus. Potyvirus infection can be easily detected through serological (ELISA, ISEM, RIA, Immunodiffusion and Immunoblotting) and nucleic acid based techniques. Tissue culture accompanied by chemotherapy and thermotherapy are useful for quality planting material from Alstroemeria infected with potyvirus. Besides these, control of aphids, thrips , weeds, nematodes etc. and use of resistant cultivars can also be used for controlling potyviruses. This article emphasizes on number of potyvviruses infecting alstoemeria crop, their control and quality improvement so that such virus free planting mate rial be utilized by Indian farmers as a source of employment and income generation.


"Labor market," "unemployment"... These concepts, which until recently seemed to be remote and unacceptable within the socioeconomic structure of our society, are now becoming realities of our everyday life. The USSR Supreme Soviet's enactment of the "Principles of Legislation of the USSR and the Union Republics Concerning Employment of the Population" is essentially the first legislative act calling for the creation of a labor market in the country and acknowledging the status of unemployed persons. This document stipulates the legal, economic, and organizational principles of employment under conditions of the market economy. In order to ensure practical implementation of the policy of employment and provide social guarantees, a state employment service has also been set up on various levels—from the all-union to the district level.

This research aims at finding out and analyzing how good corporate governance produces financial statement which has a certain quality that affects the company's financial performance. The population of this research is a sub-sector of the property listed on the Indonesia Stock Exchange period of 2014-2018, with the selection of samples based on the selected purposive sampling of 16 companies. The data was analyzed by using multiple linear regression by conducting classical assumption tests and hypothesis tests. The results of the research show that good corporate governance measured with the commissioner, foreign ownership and audit committees are simultaneously and significantly affect the financial performance measured by return on asset. Partially the Board of Commissioners have a significant effect on financial performance with a substantial of 1.299. Foreign ownership and audit committees have no significant effect on the financial performance in which the value of sig is > 0.05. The value of coefficient of determination of R 2 amounted to 72.9% showed that Return On Asset variation can be explained by the variation of Board of Commissioners, foreign ownership and audit committee and the remain is 27.1% which is explained by other factors that do not exist in this research. The results of this research proved that the most dominant variable which has significant effect to the financial performance is the Board of Commissioners. This should be a consideration for the company in the election or designation of the Board of Commissioners to improve implementation of good corporate governance principles in order to improve the company's financial performance.


Multimodal transportation has become mainstream in international freight transportation. There are many factors affecting route selection, and the two main factors are transportation cost and time. This paper establishes a model for route selection, and this model aims at the optimization of cost with time as a restriction. The K-shortest path algorithm is a good solution to this model, and a practical application of this analysis is examined.


A magneto-optical (MO) Kerr tracer based on an ellipsometer was developed for studying the surface magnetic properties of thin films. This system can be used to measure the optical properties n and k, which are strongly related to the magneto-optical parameters qk and hk. In order to carry out measurements on materials having a small qk we have developed a multiple reflection sample holder which gives an enhancement of the rotation. The behavior of the sample holder is explained in terms of Jones matrices. The optical and magneto-optical properties for a thickness series of Co-Cr films were measured. Comparative measurements on other systems gave similar results.

Objective To establish a rapid and accurate method to detect the Legionella Pneumophila(LP).Methods The loop-mediated isothermal amplification(LAMP) to amplify the specific DNA fragments of LP and the gene chip technology was further used to identify the LP sequence.Results The DNA bands corresponding to LP DNA could be specifically amplified by the LAMP reaction.For normal PCR,the minimum dilution of genomic DNA was 10-5,however,for the LAMP,the minimum dilution of genomic DNA was up to 10-7,so the sensitivity of the LAMP reaction is about 100 times higher than of normal PCR.The combination of the LAMP and gene chip contributed to demonstrating the specific LP sequence signal.Conclusion Combination of LAMP and gene chip is a simple,accutate and rapid technology to detect LP with,high sensitivity and specificity.


Brown-Séquard syndrome is an uncommon condition accounting incomplete spinal cord injury, manifesting as ipsilateral weakness and proprioception loss, associated with contralateral pain and temperature sensation loss. Brown-Séquard-plus syndrome (BSPS) has not quite a well-stablished definition, but usually is defined as a Brown-Séquard syndrome associated with clinical findings compatible with another spinal cord tract. We present a pearls & oysters article naming the most relevant findings and aspects to evaluate in this pathology, throughout a clinical case where a patient presents a Brown-Séquard-plus syndrome as the initial attack in multiple sclerosis.


We report the synthesis and characterization of new alkyl-substituted 1,4-di(thiophen-2-yl)buta-1,3-diyne (R-DTB) donor building blocks, based on the −C≡C–C≡C– conjugative pathway, and their incorporation with thienyl-diketopyrrolopyrrole (R′-TDPP) acceptor units into π-conjugated PTDPP-DTB polymers (P1–P4). The solubility of the new polymers strongly depends on the DTB and DPP solubilizing (R and R′, respectively) substituents. Thus, solution processable and high molecular weight PDPP-DTB polymers are achieved for P3 (R = n-C12H25, R′ = 2-butyloctyl) and P4 (R = 2-ethylhexyl, R′ = 2-butyloctyl). Systematic studies of P3 and P4 physicochemical properties are carried using optical spectroscopy, cyclic voltammetry, and thermal analysis, revealing characteristic features of the dialkynyl motif. For the first time, optoelectronic devices (OFETs, OPVs) are fabricated with 1,3-butadiyne containing organic semiconductors. OFET hole mobilities and record OPV power conversion efficiencies for acetylenic organic ma...


My thanks to David J. Bolton for his kind words about my work in "Contesting the Covenants," as he subtitled his interesting essay in the Winter, 2010, issue. (1) I would like to offer two comments about it. First, he describes the dialogue document "Reflections on Covenant and Mission" (R.C.M.), published jointly in 2002 by the Secretariat for Ecumenical and Interreligious Affairs (S.E.I.A.) of the United States Conference of Catholic Bishops (U.S.C.C.B.) and the National Council of Synagogues (N.C.S.) as "a text claiming to be jointly issued by Catholic bishops in the United States and their Jewish dialogue partners." (2) I would like to clarify that R.C.M. itself never made such a claim. Confusion arose from the wording of a press release issued by the U.S.C.C.B.'s Office of Communication on August 12, 2002, which led both religious and secular reporters to mistakenly conclude that the U.S. bishops as a group had promulgated the document. On August 16, a second press release was issued to correct this misperception: Cardinal William H. Keeler of Baltimore said today that a document made public August 12 represents the state of thought among the participants of a dialogue that has been going on for a number of years between the U.S. Catholic Church and the Jewish community in this country. Cardinal Keeler, the U.S. Bishops' Moderator for Catholic-Jewish relations, said that the document, entitled Reflections on Covenant and Mission, does not represent a formal position taken by the United States Conference of Catholic Bishops (USCCB) or the Bishops' Committee for Ecumenical and Interreligious Affairs (BCEIA). The purpose of publicly issuing the considerations which it contains is to encourage serious reflection on these matters by Jews and Catholics in the U.S. In other words, R.C.M. was the latest of a series a "dialogue documents" or working papers issued by an ongoing official national dialogue between delegates of the Catholic Church and Reform, Conservative, and Reconstructionist Jewish communities. While certainly not a formal U.S.C.C.B. statement, R.C.M. was thoroughly a product of the S.E.I.A. in collaboration with the N.C.S. Its Catholic section was drafted by U.S.C.C.B. personnel and theologians appointed by Cardinal Keeler and vetted and revised by officers in the S.E.I.A. and the Office of Doctrine. The decision to release the working paper publicly was advocated by Keeler and other bishops participating in the dialogue: "Cardinal Keeler noted that various quotations in the paper were the results of a bishops' synod and are authoritative teachings of the Church." (3) Statements from the S.E.I.A. in 2009 imply that R.C.M. had little connection with official ecclesiastical structures, which is simply not the case. Second, in discussing Nostra aetate #4, Bolton observes that, while groundbreaking, that declaration did "not address the issues of covenant and mission," (4) though he notes that there is some reason to interpret the final text as saying "that the Jews' 'covenants' (in the plural, citing Rom. …

A flame retardant organopolysiloxane composition, the composition exhibits excellent heat resistance, and even when exposed to high temperature, in the cured product suffers no foaming, which means that no water and moisture electrical insulating properties or performance degradation occurs. Said composition comprising: (A) an organopolysiloxane represented by the general formula (1) :( wherein R1 represents a hydrogen atom or a monovalent hydrocarbon group, R2 represents a monovalent hydrocarbon group, each Z independently represents an oxygen atom or a divalent hydrocarbon group , a represents 0, 1 or 2, and n represents an integer of 10 or greater), (B) boehmite, and (C) the organosilicon compound represented by the general formula (2): R3bSiX4-b (2) ( wherein R3 represents a monovalent hydrocarbon group, X represents a hydrolyzable group, and b represents 0, 1 or 2), or a partial hydrolysis - condensation product, or a combination thereof.


In recent years, the aerodynamic noise generated by centrifugal fans is receiving increasing attention because of strict environmental noise level restrictions and customer demands. The noise generated by fans is due to aerodynamic sources and to other several sources, such as, for instance, by the fan drive, by bearings and gearing, and, when present, by the inverter. Additional noise sources can be also due to structural resonance effects induced by periodic forces associated with the blade passing frequency or vortex shedding. Usually, these additional noise sources are dominated by aerodynamic noise generated by the fan, in particular when the intake and outlet of the fan are free. On the other side, if fan intake and outlet are ducted, the additional sources can relevantly contribute to overall sound generation. In this paper, an experimental characterization of the noise generated by industrial centrifugal fans when both inlet and outlet are ducted is presented. To do this, an experimental facility has been design and set up, and the sound power measured by means of the procedures outlined in the ISO 3746 international standard. A number of different type of centrifugal fan (straight-, forward- and backward blade) in different working conditions were tested, resulting in 133 different runs. These amount of data were then processed and a general formula for fan noise estimation obtained as a function of the geometrical and fluid dynamic parameters is derived. Moreover, specific coefficients with respect to blade geometry for the determination of the A-weighted frequency spectrum are presented. Finally, auxiliary devices or other features, such as inverter, thickness of the casing, acoustic insulation, electric motor shaft, are analyzed and some general rules to estimate their influence on sound power level quantified.Copyright © 2011 by ASME


Long Hu, Zhenguo Liu, Yibo Wang, Jiajun Ou, Dongxu Liu School of Aeronautic Science and Engineering Beihang University(BUAA) Beijing, China e-mail: firstname.lastname@example.com Abstract—Finite element analysis for the strength prediction of 3D braided composites structures are presented in this paper. A strength analysis model was established to investigate the strength characteristics of the 3D braided composites. Repeated unit-cell (RUC) model was used in this model to describe the microstructure of 3D braided composites and differences between yarn configurations in corner, surface and interior RUCs were considered. Composite damage model were introduced into the yarns of the RUCs in the analysis model and the macroscopic failure and damage evolution of the 3D braided composites structures were characterized by the damage of yarns by nonlinear homogenization method. To validate the veracity of this model, a user defined material subroutine (UMAT) was developed to introduce this model into the finite element analysis software and the damage progression of a 3D braided composite structure under three-point bending was simulated. Good agreements were achieved in the loaddeflection curves and damage morphology between experimental and numerical results.


This is an attempt to put together geological and geophysical data. Out of the three alternatives for the composition of subcrustal substance - basalt, eclogite, peridotite ‐ the author prefers the last one. It is emphasized that igneous activity in folded (geosynclinal) provinces is substantially different from that in the platforms. In the latter, magma can be formed only in the fusing (complete or partial) of the mantle substance; in the former, conditions are favorable for the emergence of regenerated magmas. Generation of magmas is assisted by deep faults which release the pressure. Lighter peridotite melts rise toward the MohoroviCic surface; the heavier remain below. The author carries his peridotite concept to its logical conclusion, attempting to explain such phenomena as the Gutenberg layer. He illustrates it with such instances as the islands of Tahiti and Oahu, and St. Paul's Rocks. He admits that much more study is required, especially with regard to permanency of the continents and oceans. ‐...


The need for a quick and radical green transition gives a key role to the financial system as the main source to fund the change. This debate also involves the development of banking regulation tools able to serve the transition. Building on previous works, we propose a method to weight banks' assets that combines conventional financial risks and environmental risks to calculate prudential capital requirements, and we apply it to the EU Taxonomy's technical screening criteria to build an environmental risk indicator based on the buildings' energy consumptions. We show how to calculate the tool endogenously for the taxonomy sections related to buildings (new construction, purchase of building, renovation), thus proving its immediate enforceability, using data from the Lombardy's housing stocks. Finally, we conduct a stress test for the Italian banking system showing that our proposal would be an effective incentive for the banks to fund the green transition of the construction sector. Disclaimer: The views expressed are those of the authors and do not involve the responsibility of the Bank of Italy or RSE.


Objective To observe the migration ofmesenchymal stem cells (MSCs) transfected with recombinant lentiviral vectors carried brain derived neurotrophic factor (BDNF) gene from lateral ventricle to intracerebral hemorrhage stove in rats and to discuss the protective effect of BDNF on MSCs.Methods Intracerebral hemorrhagic models were constructed in 60 SD rats and randomly divided into 4 groups:phosphate buffer solution (PBS) group,BMSCs group,BMSCs-enhanced green fluorescent protein (EGFP) group and BMSCs-EGFP-BDNF group (n=15); PBS,BMSCs,lentiviral vector (LV)carried EGFP and LV carried BDNF-EGFP were,respectively,injected into the lateral cerebral ventricle of each group; 7,14 and 21 d after the injection,BDNF protein expression in the BMSCs of each group was detected by Western blotting and immunofluorescence; the migration of BMSCs from lateral ventricle to intracerebral hemorrhage stove was observed by signal labeling immunofluorescent staining.Results Western blotting and immunofluorescence showed that the BDNF protein expression in the MSCs-EGFP-BDNF group was significantly higher than that in the MSCs group and MSCs-EGFP group (P<0.05); signal labeling immunofluorescent staining of brain tissue section indicated that the MSCs-EGFP-BDNF group had significantly larger number of BMSCs-positive cells which migrated to the surrounding issues of intracerebral hemorrhage stove than MSCs group and MSCs-EGFP group (P<0.05),while there were no significant differences between the latter two except on the 7th d of establishment of models.Conclusion BMSCs modified with recombinant LV carried BDNF gene have high expression level of BDNF,indicating that BDNF performs a protective effect on BMSCs.

In total, there are more than 80 species of Orthoptera in Germany. "Grasshoppers are very important for many open grassland ecosystems," states zoologist Sebastian König from the Biocenter of the Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany: "The insects are an important food source for birds. And as herbivores, they remove up to 30% of the plant biomass in a meadow, thus promoting the cooccurrence of many plant species."


In order to detect the developing and changing relationship of spatio-temporal data,this paper studied the dynamical correlation technology of spatio-temporal data,proposed and implemented a dynamic correlation algorithm and a basic type of spatio-temporal change.This algorithm combined geometrical correlation with attributes correlation to launch matching and detecting changes,so that it matched spatio-temporal data and extracted changes automatically.This algorithm could solve the relationships as one to one,one to multi,multi to one and multi to multi changes,and detect the moving and changing states of spatio-temporal objects.


A longitudinal study was carried out in Nakasongola District located in Central Uganda to determine a suitable organic bait for subterranean termites. A random block experiment comprising three baits: maize cob, sugarcane bagasse and pine saw dust, each with 5 replicates was carried out for a period of five weeks as follows:Termite bait stations were placed around 5 randomly selected active Macrotermes bellicosus termitaria found within the same hectare. Each mound was surrounded by three 2.5 dm 3 bait stations placed in a circle, 1m from the center of the mound. As bait, the three stations comprised maize cobs, sugarcane bagasse and pine saw dust respectively. For five weeks, the movable buckets were picked each week and immediately their contents were poured into plastic basins, to separate the remaining bait from soil carried into the stations by termites, The volumes of remaining bait after each week of termite activity was measured using a calibrated 2.5 dm 3 bucket and recorded. Fresh bait was placed into the station and reset. Statistical analysis was carried out using one way analysis of variance, to determine significant differences in mean bait volume within traps following termite activity. Post hoc analysis was carried out using least significant difference. Analysis of variance revealed significant difference (p = 0. 000) in mean bait volume of maize cobs, sugarcane bagasse and pine saw dust in week 5 of the study. Post hoc analysis revealed significant difference in mean bait volume between cob and sugarcane bagasse (p = 0. 000) and cob and saw dust (p= 0. 000) in the fifth week of the study. There were no significant differences in mean bait volume of sugarcane bagasse and pine saw dust. Termites do exhibit bait preference with maize cobs being the most preferred among those tested. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 29-08-2019 Date of Acceptance: 14-09-2019 -------------------------------------------------------------------------------------------------------------------------------------

Beta gallium oxide (β-Ga2O3) shows significant promise in high-temperature, high-power, and sensing electronics applications. However, long-term stable metallization layers for Ohmic contacts at high temperatures present unique thermodynamic challenges. The current most common Ohmic contact design based on 20 nm of Ti has been repeatedly demonstrated to fail at even moderately elevated temperatures (300–400 °C) due to a combination of nonstoichiometric Ti/Ga2O3 interfacial reactions and kinetically favored Ti diffusion processes. Here, we demonstrate stable Ohmic contacts for Ga2O3 devices operating up to 500–600 °C using ultrathin Ti layers with a self-limiting interfacial reaction. The ultrathin Ti layer in the 5 nm Ti/100 nm Au contact stack is designed to fully oxidize while forming an Ohmic contact, thereby limiting both thermodynamic and kinetic instability. This novel contact design strategy results in an epitaxial conductive anatase titanium oxide interface layer that enables low-resistance Ohmic contacts that are stable both under long-term continuous operation (>500 h) at 600 °C in vacuum (≤10−4 Torr), as well as after repeated thermal cycling (15 times) between room temperature and 550 °C in flowing N2. This stable Ohmic contact design will accelerate the development of high-temperature devices by enabling research focus to shift toward rectifying interfaces and other interfacial layers.


After her curriculum proposal is presented, Noddings' feminine ethics is submitted to a critique through an interpretation of her three books. Her distortion of Gilligan and Chodorow is explained. Indebtedness to male sources is noted. The over-emphasis upon good and upon first-person experience is criticised and traced to feminist rage, which is interpreted as the result of the oppression of women. Noddings' suppressed 'Kantianism' is explicated to maintain the dialectic between so-called male and female voices. Main strengths of her curriculum proposal are interpreted more broadly than her perspective allows to indicate a promising return to normative, macro-theory of education.


For the defects of Diffie-Hellman key exchange and ECDH protocol,an authenticated key agreement protocol is proposed. This proposed protocol is of such security properties as key uncontrollability,key confirmation,perfect forward security,and resistance to known key attacks. Furthermore,this protocol as compared with traditional ones,is simple in management,low in overhead,and high in security,and could achieve secure key agreement and verification between the communication parties with lower computing cost and higher efficiency. Analysis indicates that this protocol is fairly applicable to the end-to-end key management of large-scale networks.


A necessary aviation reconnaissance means for modern army aviation force, reconnaissance helicopters play important roles in several recent local wars and attract the focus of military authorities of many countries.

The process of privatizing state-owned property assets such as agricultural or manufacturing enterprises is considered in the paper. An optimal timing model is employed to investigate the question of the best time to privatize a state-owned property asset. Beyond the optimal timing question, the author also analyses the simultaneous question of the optimal amount of new fixed investment that should accompany privatization. In both cases, comparative static analysis is employed to determine how fluctuations in net income streams before and after privatization and tax rates that apply to land and capital improvements affect the optimal timing and capital investment decisions. The results provide important insights for the design of privatization policies.


The question of bilharziasis in Egypt is of vital importance to the nation. The disease is sapping the energy of the people, and widespread campaigns are now being conducted with energy in the hope of completely eradicating the disease. In 1928 Prof. Mohamed Sobhy Bey 1 published a report of a case of bilharziasis of the conjunctiva, the first of its kind. For several years I have been unsuccessfully looking for a report of bilharziasis of the nose, pharynx or larynx. I have not found any such condition reported. Prof. Khalil Bey, an eminent parasitologist, told me that bilharziasis in the nose of bovines has been reported 2 but that he did not know of any occurrence of this condition in man. I encountered the disease in a patient with laryngeal obstruction. I believe this is the first case of laryngeal bilharziasis to be reported. A Man aged 35 was admitted to


Microscopic characterization of generation lifetimes in a SiO2/Si structure has been carried out using scanning capacitance microscopy (SCM). Generation lifetimes could be investigated by monitoring the capacitance transient due to inversion layer formation. The validity of local capacitance transient measurements by SCM was verified by comparing with the results of conventional capacitance transient measurements using a MOS capacitor. Furthermore, it was demonstrated that SCM can be used for imaging of the formation process of the inversion layer on a nanometer scale.


Suicidal ideation (SI) and suicide attempts (SAs) among adolescents are a significant public health
concern worldwide. The current study extends previous research by exploring the association between adverse childhood
experiences (ACEs) and SI and SAs in a sample of adolescent inpatients as well as identifying specific predictors for
increased risk of SI and SAs.

Associations between ACE scores and self-reported SI and SAs were explored in a sample of 154 adolescent
inpatients via clinical interview and by analyzing the association between cumulative ACE scores and scores on the Suicidal
Tendency scale of a larger personality measure. We also tested for independent relationships between 19 ACEs and SI and
SAs to determine unique predictors for suicidality.

One-way ANOVA analyses revealed that those who attempted suicide reported significantly more ACEs compared
to those who did not attempt suicide. Witnessing violence in the home, school, or neighborhood, and experiences of
discrimination increased one's likelihood to attempt suicide by two to threefold, while sexual abuse, neglect, and physical
abuse increased this likelihood by three-to-fourfold. Stepwise linear regression analyses demonstrated that emotional abuse,
living with someone who had mental health problems or attempted suicide were most associated with elevated Suicidal
Tendency scores on a personality measure.

Early identification, education and intervention are imperative to limit or eliminate ACEs from occurring.
The impact of cumulative as well as specific ACEs on suicide risk should be closely considered as areas for such
intervention. Areas for future research include extending to include more diverse populations such as the LGBTQ
community as well as more ethnically and racially diverse populations.


BACKGROUND
The creation of vascular access is an essential condition for providing haemodialysis, which remains the only option for most patients suffering from end-stage renal disease. Selection of the type of vascular access affects patients' clinical outcomes, access maintenance frequency, risk of infection and major adverse cardiac events during dialysis. To improve the decision-making process, we performed a retrospective clinical data analysis of dialysed patients and critically compared the survival rates between two types of vascular access applied during dialysis therapy during a 5 years follow-up period.

METHODS
Using nationally representative data from 18 dialysis centres across Slovakia, we explore and compare survival rates of 960 adult patients undergoing haemodialysis using either a central venous catheter (CVC) or an arteriovenous fistula (AVF). Length of dialysis, protein malnutrition and comorbidities were examined as possible covariates that might influence survival rates.

RESULTS
Chances of surviving for a one-year period were higher by 52% in AVF patients compared to CVC patients (HR 1.52; 95% CI 1.27-1.83; p<0.001) regardless of age, sex, nutritional status, time spent on dialysis and comorbidities. The presence of cardiac congestion (HR 1.26 (95% CI 1.06-1.50), p<0.01) and malnutrition (protein malnutrition: HR 0.98 (95% CI 0.96-1.00), p<0.05; lean tissue index: HR 0.79 (95% CI 0.67-0.93), p<0.01) decreases chances for survival.

CONCLUSIONS
A functional arteriovenous fistula is a significant predictor of survival in the population dependent on haemodialysis, independently of sociodemographic parameters and serious comorbidities. Therefore, if various types of vascular accesses are applicable for the patient, AVF should be prioritized over CVC.


Chinese Prosaic Ode is a unique literature style.Narrative study on prosaic odes had developed along with the rejuvenation of prosaic odes' study,which is an important expression of the development in the study on prosaic odes.Through reviewing related studies in this field,it is found that preliminary achievements have been made in such aspects of narrative study on Prosaic Odes as the influence of its literary style,Han prosaic Odes,Tang Prosaic Odes,and Vulgar Prosaic Odes.In contrast to the achievements in the study on Prosaic Odes,narrative study on Han Prosaic Odes especially is considerably insufficient both in scope and in depth.


Branched polyethylene/linear polyethylene blends (BPE/LPE) were prepared using the combined Ni(α-diimine)Cl 2 (1) (α-diimine = 1,4-bis(2,6-diisopropylphenyl)-acenaphthenediimine) and {Tp Ms* }TiCl 3 (2) (Tp Ms* = hydridobis(3-mesitylpyrazol-1-yl)(5-mesitylpyrazol-1-yl)) catalysts supported in situ on methylaluminoxane (MAO)-modified silica (4.0 wt.-% Al/SiO 2 ). The polymerization reactions were performed in toluene at two different polymerization temperatures (0 and 30 °C) and several nickel molar fractions (x Ni ), using MAO as external cocatalyst. At all temperatures, the activities show an approximate linear correlation with x Ni , indicating a non-synergistic effect between the nickel and the titanium species. Higher activities were found at 0 °C. The melting temperatures for the polyethylene blends produced at 0 °C decrease as x Ni increases in the medium, indicating good compatibility between the polyethylene phases made by both catalysts. The melting temperature (T m ) of the polyethylene blends was shown to depend on the order in which the catalysts were immobilized on the MAO-modified silica support. The initial immobilization of 1 on the support (2/1/SMAO-4) affords polymers with a lower T m than those produced with 1/2/SMAO-4. In addition, scanning electron microscopy (SEM) studies revealed that the spherical morphology of the supported catalyst is replicated in the polyethylene particles.

Love and Life is always the topic in human society. One puzzle is how to balance the immortal love and the mortal life: Anna killed herself for love and Zijun also ended herself at the loss of love. Their tragedies represent not only their fate in their times,but also some principle long practiced by people of different nations. This paper gives a tentative study on the origin of their tragedies,and the way to adapt to woman's new roles when necessary.


SINCE 2012 I HAVE BEEN WORKING WITH historians, educators, artists, and filmmakers to develop the Lost Stories Project, which seeks from the public little-known stories from the Canadian past, gives these stories to artists who transform them into inexpensive pieces of public art on appropriate sites, and documents the artists' creative process through the production of short films.1 When I came up with the concept for the project it was largely in the context of my own research over the past 15 years, which had explored the public representation of the past in both Quebec and Atlantic Canada with a particular emphasis upon the backstory that is usually impossible for the casual observer to perceive. In the case of Quebec, I examined the public memory of Samuel de Champlain and Mgr. François de Laval, generally viewed as the founding fathers of French-speaking Quebec: one the secular father (responsible for the settlement at Quebec City) and the other the religious founder (the first Roman Catholic bishop of Quebec).2 In regards to Atlantic Canada, I focused my attention on efforts in the early 21st century to commemorate both the founding moment for Acadians – the attempt to establish a permanent settlement on Île Ste-Croix in 1604 (so four years before Quebec City) – and their moment of trauma – the deportation of the Acadians between 1755 and 1763, or what they call "le grand dérangement."3 I learned from these projects what others have also observed: namely, that public remembrance of the past – through such tools as the construction of


In November 2017, Hecht and Kamlofsky submitted HK17, a quaternion(octonion)-based Diffie-Hellman key exchange protocol, to NIST post-quantum cryptography project, and thought that at least O(p8) arithmetic operations are needed for a passive adversary to recover the shared key where p is the modulo used in the scheme. Later, Bernstein and Lange pointed out that the shared key can be recovered with O(p) arithmetic operations, which implies that HK17 with small p is not secure. However, their attack does not work in practice for the scheme with sufficiently large p, although the scheme is still efficient. In this paper, we propose an attack to show that just constant arithmetic operations, or $\tilde O\left( {\log p} \right)$ bit operations, are enough to recover the shared key for a passive adversary. Note that even the legal party in the protocol needs at least $\tilde O\left( {\log p} \right)$ bit operations to establish the shared key. We break HK17 completely in the practical sense.


This study proposed hybrid coupled shear wall in the steel plate insertion method, which is capable of reinforcing the shear strength of the entire wall without increasing wall thickness in the wall-slab apartment buildings. The proposed hybrid coupled shear wall was tested for its effectiveness, shear strength and seismic behavior in experiment. As a test result, the shear strength improvement by the proposed hybrid coupled shear was found effective. Integral-type of steel plate insertion was found more effective than separate-type steel plate insertion. In this case, if the stud enforcement method proposed in this study was used, the shear strength of hybrid coupled shear wall was recommended to calculate using the KBC2016 0709.4.1(3) method. The steel plate inserted in the proposed method was found to have no significant impact on the final fracture behavior and bending strength of hybrid coupled shear wall. The shear strength at the final destruction of the wall was merely about 1/50 of the entire design shear strength. Thus, it is deemed that the wall was over excessively designed regarding the shear force in the existing design method. This finding indicates further study on wall designing to ensure effective and economic designing based on appropriate strength estimation under the destruction mechanism.


In this article, authors Matthew Wolfgram, Brian Vivona, and Tamanna Akram present a comparative case study analysis of five students from a comprehensive, urban Hispanic-Serving Institution whose experiences exemplify a coordination of intersectional factors that amplify barriers to internship participation. Research shows that college internships yield academic, economic, and professional benefits. However, the opportunity to locate and participate in internships is not equal across student demographic and socioeconomic contexts. There are multiple complex barriers to internship participation for students who are socially and institutionally minoritized by race, gender, and other contextual factors, including finances, work responsibilities, travel, and gendered familial obligations. These factors intersect with systems of power and privilege to amplify challenges and foreclose futures. The authors argue that the delineation of barriers into types alone, such as financial, social, and cultural, without additional analysis of the dynamics of how such barriers intersect and amplify, runs the risk of misconstruing students' actual experiences when they struggle to access internships and other educational opportunities.


Ethylenediaminetetraacetic acid (EDTA), when used as a main chelator for complex plant microfertilizers, causes many negative environmental effects; therefore, new compounds or new use of the known compounds to replace EDTA have been widely studied. In the present study, biodegradation rate, plant (Raphanus sativus) growth stimulation and ecotoxicity towards Daphnia magna and Chlorella vulgaris of iminodisuccinic acid (IDS), considered as an alternative for EDTA in agriculture, has been investigated. It was demonstrated that IDS' biodegradation rate over 28 days was 28.1%, which is 4.5 times higher than that of EDTA. Similar to EDTA, complexation with metals led to an increase in the degradation rate by 1.8-fold. The majority of compounds were degraded within first 7 days. The GI values for IDS implemented at concentrations of 100 mg/L (both in pure form and in combination with microelements) were 2.4–2.6 times higher than those of EDTA. The ecotoxicity index EC10 of IDS was estimated to be 2.0 g/L and 5.8 g/L towards D. magna and Ch. vulgaris which are 4.1- and 10-fold higher than those for EDTA, respectively. It can be concluded that IDS is a promising agent to chelate microelements used in plant nutrition.


Ecological risk assessment is a scientific tool designed to evaluate the ecological effects of human activities. Historically, risk assessments have been used as a tool to assess risks to human health from environmental exposures to toxic pollutants, or to assess the ecological effects of toxic releases. The middle Snake River has been used as one of five EPA case studies to demonstrate the applicability of risk assessment at the watershed level for assessing the relative effects of multiple stressors on key ecological components of the aquatic ecosystem. The state and federal resource managers and the public identified restoration and protection of native cold water salmonid species and rare and endangered invertebrate species as a management goal. The risk assessment sought to characterize the significance of reduced water flow, sedimentation, and increased nutrients on these ecological components through a process of problem formulation, stressor-effects analysis, and risk characterization. The desired outcome of the assessment is to identify conditions that must be attained to support the management goal as one step in evaluating management options for ecological protection in the watershed.


Introduction. The object of this paper is to prove some formulae for Jacobi polynomials. The formulae (6), (7), (9), (10) and (13) are believed to be new.


Electronic Music (EM) is a popular family of genres which has increasingly received attention as a research subject in the field of MIR. A fundamental structural unit in EM are loops—audio fragments whose length can span several seconds. The devices commonly used to produce EM, such as sequencers and digital audio workstations, impose a musical structure in which loops are repeatedly triggered and overlaid. This particular structure allows new perspectives on well-known MIR tasks. In this paper we first review a prototypical production technique for EM from which we derive a simplified model. We then use our model to illustrate approaches for the following task: given a set of loops that were used to produce a track, decompose the track by finding the points in time at which each loop was activated. To this end, we repurpose established MIR techniques such as fingerprinting and non-negative matrix factor deconvolution.


A kind of new harrow disk made up of as -cast bainitic steel is studied and produced to replace the 65Mn steel and the traditional manufacturing craftwork. The research indicates that the wear of disk is the Low-Pull impacting grit wear in the soil. But the new as-cast bainitic steel has many characteristics such as greater hardness and tenacity, so the wear resistance of the new bainitic steel is better than the 65Mn steel that has been heat treated.


A key issue in designing software multicast algorithms is to consider the trade-off between performance and portability. Portable software multicast algorithms based on generic communication models cannot capture some architecture-specific features. Without considering the underlying network architecture, these multicast algorithms may not achieve the truly optimal performance when implemented in real networks. The objective of this research is to investigate architecture-dependent tuning on performance of multicast algorithms developed based on architecture-independent models. Specifically, we intend to optimize the multicast algorithm based on the parameterized communication model. We propose two multicast algorithms, OPT-mesh and OPT-min which are the optimized versions of the parameterized multicast algorithm for wormhole-switched mesh networks and BMIN networks, respectively. Using our flit-level simulator the performance of both algorithms are compared with the architecture-independent version of the parameterized multicast algorithm and two other well-known network-dependent algorithms based on the binomial tree.


ASKED TO PLACE THE TWO ACCOMPANYING ARTICLES on Latin American labor history in the broad context of the field, I began reflecting on what may first appear as a paradox. On the one hand, the world labor movement is arguably at its lowest ebb in this century. Rates of unionization, to take one important index, have been declining in many capitalist countries, most significantly in the United States, where union density today stands at roughly 16 percent of the nonagricultural labor force, down from about 29 percent as recently as 1975 and only half of the all-time high of 1953, when it reached 32 percent.' The collapse of the so-called "workers' states" of Eastern Europe, especially the disintegration of the Soviet Union itself, has involved far more than the elimination of the Soviet bloc and the end of the Cold War. Ideologically, it has placed socialist goals and Marxist philosophy itself decidedly on the defensive.2 For more than a century, Marxist socialism inspired much of the world labor movement and informed, or deeply influenced, much of the scholarship on labor, especially the field of labor history. Now, however, neo-liberalism, not Marxism, is the philosophy that is sweeping the globe. In the "new world order" of free trade and privatization, market forces are to unleash the productive potential of all human beings and sweep away inefficiencies of the bureaucratic, interventionist, social welfare state. In this new world, unions, the subject of traditional labor history, have no theoretical or practical place. On the other hand, as this extraordinary historical transformation has been unfolding, Western Marxists have been fashioning a large body of innovative work on labor that ranks among the best scholarship of recent decades. Most historians, regardless of specialization, are aware of the contributions of British labor scholar Edward Palmer Thompson.3 His work, in some sense a response to the Stalinist revelations of the 1950s, influenced a generation of Western social and labor historians. They have focused on the experience of unorganized as well


Chromia-zinc oxide catalysts have been prepared by the impregnation method using non-sintered and sintered zinc oxide as carriers. Measurements of magnetic susceptibility have been made for these two series of catalysts of varying composition. The values of gram susceptibility and the mean oxidation number of chromium in the samples oxidized with air at room temperature are nearly independent of the content of chromium. After oxygen-treatment at 250° or 450°C has been carried out, however, the surface oxidation becomes appreciable in the samples of low content of chromium, and the variations in the susceptibility and the mean oxidation number suggest that the dispersed structure of chromia depends on the composition of the catalyst. It appears that chromic ions are distributed in the two compounds, namely the thin layers of chromia on the catalyst surface and the relatively large crystallites of zinc chromite and, as the chromium content is decreased, the former becomes more important. By comparison betwe...


The nutritional properties of the fruit juices which are available in Dhaka city, Bangladesh, was studied and found that the nutritional properties are higher in the fresh fruit juices compared to the processed fruit juices. The pH range in fresh juices was 3.40 ± 0.00 to 4.50 ± 0.00 whereas it varied in processed juices from 2.70 ± 0.01 to 4.10 ± 0.00. The total soluble solid content was found maximum in fresh and processed mango juices, 23.53 ± 0.53% and 19.74 ± 0.71%, respectively. The highest amount of vitamin C was observed in the fresh guava juices (57.76 ± 5.32 mg %). The significant (p < 0.05) variations of mineral contents are found. Manganese was not detected in the processed fruit juices and in the fresh juice. It was high in mango juices (5.84 ± 0.83 mg %). Among the processed fruit juices iron was found only in the orange juices (1.05 ± 0.27 mg %) while it was high in the fresh litchi juices (7.05 ± 1.07 mg %).


The release of hydrogen peroxide (H2O2) by the fertilized sea urchin egg has been shown to assist in the prevention of polyspermy [Coburn et al, 1981; Boldt et al, 1981]. Physiological data suggested that egg-derived H2O2 reacts with a phenylhydrazine-sensitive sperm peroxidase to inactivate sperm, while a 3-amino-1,2,4-triazole-sensitive catalase acts to protect sperm from H2O2 [Boldt et al, 1981]. Strongylocentrotus purpuratus sperm contain heat and pronase labile catalase and peroxidase activities. Differential extraction of sperm (hypotonic phosphate buffer for catalase and Triton X-100 at high ionic strength for peroxidase) results in complete separation of these enzyme activities. The catalase is highly sensitive to inhibition by azide and 3-amino-1,2,4-triazole, and less sensitive to inhibition by phenylhydrazine. The peroxidase is highly sensitive to inhibition by phenylhydrazine and relatively insensitive to 3-amino-1,2,4-triazole and azide. These results show that two distinct H2O2 reactive enzymes, catalase and peroxidase, are present in sea urchin sperm, and are consistent with our hypothesis concerning the biological functions of these enzymes in fertilization.


To meet the requirement of detection range,multi-mode detection was adopted in the wind-profiler.The selected data of cross height was important for the quality of wind profile.Given the unsatisfying effect on data integration using the traditional method,the statistics for the diversing of the profile data on the multi-mode detection was done with the reason analyzed.Based on this,a new scheme of the data integration was brought forth in which the vertical coherence threshold obtained by the statistical method was used to confirm the data on the cross height.Test results show that the scheme improves the performance of data integration.

In this study, CdO:Ce thin films were prepared by spray pyrolysis technique on glass substrates for(3, 5 and 7%) doping concentrations of cerium with 100nm of thickness. The prepared films were characterized using X-ray diffraction(XRD), atomic force microscope(AFM), and transmittance measurements. XRD analysis exhibited a cubic crystalline structure with multi directions of pure CdO structure, and the monicline structure of Ce. The crystalline size dropped with the increasing of Ce concentration (64.4 – 44.78) nm, also the strain increased (0.034 – 0.048) rad of pure CdO and CdO:Ce7% films, respectively. The optical band gap energy (Eg) be found at (3.96, 3.98, 4.0 and 4.02) eV for the prepared CdO: Ce films with (0, 3, 5 and 7) Vol.% of concentration.


The accurate measurement of pressure sensors realizes the idea of non-interference environmental monitoring, which is very important for the application of electronic skins (e-skins).


This work shows the use of long period gratings in the petroleum sector, in two specific applications. The proposed sensors are employed both to identify substances in a simulated flow inside a pipeline, and to assess the gasoline conformity commercialized in gas stations. The gratings responses for each specific case were employed to train and to validate two different topologies of artificial neural networks: perceptron multilayer and radial base function. The obtained results show that fiber optic sensors supervised by artificial neural networks can constitute systems for smart measurement with high applicability in the petrochemical field.


: Sorghum bicolor L. Moench is a cereal producing reasonable yield in dry and semi-dry, hot and saline regions, where the production of other crops is limited. Sorghum grain is a rich source of minerals including magnesium (Mg), iron (Fe), zinc (Zn), Manganese (Mn), and calcium (Ca). How-ever, the quantity of minerals can be dependent on the different agricultural and climatic conditions. Therefore, the objective of this study was to investigate the effect of water stress on the micronutrients (Ca, Fe, Mg, Mn, and Zn) and geometrical features of ten sorghum genotypes. There were different patterns observed in terms of grain micronutrients produced under normal and deficit irrigation depending on the genotype. A high concentration of Ca (878.9 ppm), Fe (335.8 ppm), and Mn (22.8 ppm) under normal irrigation and a value of Mg (1435.36–1783.21 and 1410.81–1890.95 ppm) and Zn (1.65–20.34 and 4.04–15.13 ppm) in the normal and water stress condition, respectively, was observed in the genotypes. Water stress had more influence on Ca, Fe, and Zn concentrations in comparison to Mg and Mn. The discrimination models based on the selected geometrical features of the sorghum grains produced under normal and deficit irrigation indicated a relatively low classification accuracy (40–67%). Therefore, an integrated approach using geometric and textural features is suggested to improve classification accuracy.


Because of their superior structure property and high heat exchange efficiency,the spiral coil and spiral tube in tube heat exchangers are widely used in refrigeration,air conditioning,heat pump,chemical and other fields,it has important practical value for the study of heat transfer and pressure drop characteristics for water flowing in such heat exchangers.The heat transfer and pressure drop characteristics for water flowing in four spiral coil heat exchangers with different shapes and different sizes were experimental studied.Reynolds number range from 4 000 to 9 000,volume flow rate range from 200 to 350 L / h and heating power range from 80 ~ 350 W.The experimental results indicate: the average heat transfer coefficient and pressure drop increase with increasing Re,and the greatest average heat transfer coefficient appears in SC spiral coil,which bending radius is smallest; the greatest pressure drop appears in BE spiral coil,the second is in SC spiral coil,because of the combined influence of tube length and bending radius.The heat transfer coefficients increase with increasing heating power,the greatest average heat transfer coefficient also appears in SC spiral coil,the heat transfer coefficient in BE is always greater than in SE,and the comparison results of heat transfer coefficient in BC is changing with flow rate.The comparison of calculations with experimental results indicate: heat transfer enhancement effect of spiral coils weaken with the increasing Re,the greatest heat transfer enhancement effect appears in SC spiral coil,this is according with experimental results.The conclusion of this paper provides reference for the application of spiral coil and spiral tube in tube heat exchangers in many areas.


Objective To study the role TGF-β 1 expression in the gastric cancer and to evaluate its clinical and pathological significance.Methods The expression of TGF-β 1 was studied by using S-P immunohistochemical technique in 20 cases of normal gastric tissue and 46 cases of gastric carcinoma.Results in the gastric cancer patients,the positive rate of TGF-β 1 expression was 100%,but there was 50% positive rate in the normal gastric tissues.The TGF-β 1 expression in group with lymph node metastasis was higher than that without lymph node metastasis.Conclusion TGF-β 1 plays an important role in the progress of gastric cancer.


This paper contrasts the classroom approach to designing a system that involves both hardware and software with an actual commercial product. The team found that human factors kept the group productive in spite of changing requirements, lose role definitions and complex networking. Violations of the normal restatement of the system development life cycle can be tolerated so long as there are stron, social mitigating factors. Such violations in the 1970's lead to the microcomputer revolution.


The event data recorders on General Motors (GM) light vehicles provide a wealth of information for accident investigators. This article describes the data that is available with GM's latest software and hardware updates. The updates can be divided into several categories: changes to how data from currently supported vehicles has changed, carryover vehicle coverage and fixes for vehicle coverage, and new vehicle coverage. Among the updates is a change in display for delta-v data, enhanced explanations for some current data elements, the addition of a rollover sensor, and two new umbilical cables. More changes are planned for the future.


The stimuli color greatly affects the performance of a steady-state visual evoked potential (SSVEP)-based brain computer interface (BCI). However, few studies have evaluated the effect of stimuli color combination on the multiple-target BCI when the stimuli adopt different colors. In this study, 16 sets of colors were tested by using an online dual-task BCI, and the detection accuracy, time and information transmission rate (ITR) were measured. The results showed that the yellow-red combination achieved the highest accuracy, shortest time and highest ITR, which is the optimal choice for improving the performance of BCI.


Predicting battery remaining useful life (RUL) is used for early warning of battery aging failure and providing instructions of battery maintenance and recycling. The existing RUL prediction focus too much on decreasing the dependence of aging tests, neglecting the value of test data. In this regard, a battery RUL prediction method driven by multi-source data is proposed for EVs to make full use of the aging test data from other cells. Six lithium-ion batteries were used to verify the effectiveness of the method. The results show that the prediction error is less than only 1 cycle in the case of capacity 'diving'. In conclusion, the proposed method effectively improves the performance of RUL prediction by using multi-source data, and provides a solution for battery management in the era of big data.

An economic-environment model is used to analyze economic and environmental impact of reclaimed water utilization in Beijing. The simulation results predict the potential of 130 thousand tons T-N can be reduced for the utilization of reclaimed water by keeping GRP growth rate at 8%. 5 billion tons reclaimed water can be produced by construction of new sewage plants. The utilization of reclaimed water can alleviate water shortage and pollution in Beijing.


Background and purpose: The effect of paediatric HIV infection on neurodevelopment at preschool age is under reported in Sub -Sahara Africa where the burden lies. This study assessed cognitive outcome and health status at preschool age among Zimbabwean children, enrolled from a national PMTCT program, with vertically transmitted HIV type 1 infection followed up for 5 years. Methods: Cognitive function was assessed in 278 preschool children with Kaufman short form of McCarthy Scales of Children`s Abilities (MSCA): 25 HIV infected, 94 HIV exposed uninfected, 126 HIV unexposed uninfected (controls) and 33 with unknown HIV status. Only115 had received prophylactic single dose nevirapine at delivery, but none were on antiretroviral treatment. Results: HIV infected children did not differ significantly in global cognitive ability compared to their age matched HIV exposed uninfected and HIV unexposed uninfected peers of similar background. Mean scores were significantly lower between HIV exposed uninfected and HIV unexposed uninfected children in specific subtests representative of verbal, perceptual performance and quantitative performance. HIV infected children were significantly more stunted, had more skin disorders, and lymphadenopathy compared to their uninfected peers. Maternal age and family income were predictive of lower GCI in this study. Conclusion: HIV infected children who survive to preschool age did not manifest lower cognitive scores than established child norms. The prevalence of cognitive impairment in this study was 8.6% and was more frequent in HIV uninfected children. Chronic malnutrition as indexed by stunting was associated with poor cognitive function at preschool age. Therefore comprehensive interventions to prevent childhood HIV and malnutrition could result in significant improvement in cognitive function at preschool age and later academic achievement.


Objective To investigate whether the tendency of Th1/Th2 cell in peripheral blood is associatied with different immune states in early stage of allogeneic orthotopic rat liver transplantation.Methods Allografted rats were divided to three groups(each group n=36):syngeneic control(group A),the group of allograft treated with CsA 2 mg/(kg·d)(group B) and allograft(group C).At post-transplantation day of 1,3,5,7,14,six rats from each group were sacrificed to harvest allografted liver for pathological,percentage of CD4+CD45RC± T cell subsets in peripheral blood of recipient by flow cytometry,and additional subgroups(n=6) for observation of survival time.Results(1)The survival time of both group A and group B were significantly longer than that of group C(100 day vs 34.3±3.6 days,P0.01).(2)Apart from 1 day,the rejection grades were higher in the group C and B than that in group A and there were significant differences between the two groups(P0.05 or0.01).(3)From third day to fourteenth day post-transplantation,the ratio of CD4+CD45RC+ percentage with CD4+ CD45RC-percentage was significant higher in group C than that in group B and group A(P0.05 or 0.01).(4)There was negative correlation between ratio of CD4+CD45RC+%/CD4+CD45RC-% and rejection grades(r=-0.565,P0.01),but positive correlation existed between ratio of CD4+CD45RC+%/CD4+CD45RC-% and rejection grades(r=0.745,P0.01).Conclusion The ratio of Th1/Th2 cell in peripheral blood varied according to different immune states in early stage of allogeneic orthotopic rat liver transplantation.


Articular cartilage defects heal poorly. Autologous Matrix-Induced Chondrogenesis (AMIC) is an innovative treatment for localized full-thickness cartilage defects combining the well-known microfracturing with collagen scaffold and fibrin glue. The purpose of this prospective study was to evaluate the medium-term results of this enhanced microfracture technique for the treatment of chondral lesions of the knee. Thirty-two chondral lesions in 27 patients were treated with AMIC. Within the context of clinical follow-up, these patients were evaluated for up to 5 years after the intervention. Five different scores (Meyer score, Tegner score, Lysholm score, ICRS score, Cincinatti score) as well as radiographs were used for outcome analysis. Articular resurfacing was assessed by magnetic resonance imaging (MRI). The average age of patients (11 females, 16 males; mean body mass index 26, range 20–32) was 37 years (range 16–50 years). The mean defect size of the chondral lesions was 4.2 cm2 (range 1.3–8.8 cm2). All defects were classified as grade IV according to the Outerbridge classification. The follow-up period was between 24 and 62 months with a mean of 37 months. Twenty out of 23 individuals (87%) questioned were subjectively highly satisfied with the results after surgery. Significant improvement (P\0.05) of all scores was observed as early as 12 months after AMIC, and further increased values were notable up to 24 months postoperatively. MRI analysis showed moderate to complete filling with a normal to incidentally hyperintense signal in most cases. Results did not show a clinical impact of patient's age at the time of operation, body mass index and number of previous operations (n.s.). In contrast, males showed significant higher values in the ICRS score compared to their female counterparts. AMIC is an effective and safe method of treating symptomatic full-thickness chondral defects of the knee in appropriately selected cases. However, further studies with long-term follow-up are needed to determine whether the grafted area will maintain structural and functional integrity over time.

Methods: Animals (n = 30) were randomized into 5 treatment groups, and 7-mm full-cartilage-thickness defects were set at the trochlea and medial condyle of both knee joints and treated as follows: 2 scaffolds in comparison (collagen I/III, Chondro-Gide®; collagen II, Chondrocell®) for covering microfractured defects (autologous matrix-induced chondrogenesis), both scaffolds colonized in vitro with autologous chondrocytes (matrix-associated chondrocyte transplantation), or scaffold-free microfracture technique. One year after surgery, cartilage lesions were biomechanically (indentation test), histologically (O'Driscoll score), and immunohistochemically (collagen type I and II staining) evaluated. Results: All treatment groups of the animal model induced more repair tissue and showed better histological scores and biomechanical properties compared to controls. The average thickness of the repair tissue was significantly greater when a scaffold was used, especially the collagen I/III membrane. However, none of the index procedures surpassed the others from a biomechanical point of view or based on the histological scoring. Collagen type II expression was better in condylar defects compared to the trochlea, especially in those treated with collagen I/III membranes. Conclusion: Covering of defects with suitable matrices promotes repair tissue formation and is suggested to be a promising treatment option for cartilage defects. However, it failed to improve the biomechanical and histological properties of regenerated articular cartilage compared to microfracture alone in an ovine model under the given circumstances. Treatment Selection in Articular Cartilage Lesions of the Knee The subchondral bone in articular cartilage repair: current problems in the surgical management Bekkers J.e., Inklaar M., saris D.B. Am J Sports Med. 2009 Nov;37 Suppl 1:148S-55S Gomoll A.H., Madry H., Knutsen G., Van Dijk n., seil R., Brittberg M., Kon e. Am J Sports Med. 2009 Knee Surg Sports Traumatol Arthrosc. 2010 Apr;18(4):434-47. Epub 2010 Feb 4 Abstract Background: Several treatment options are available to repair articular cartilage lesions of the knee; however, evidence-based parameters for treatment selection are lacking. Purpose: To identify parameters for valid treatment selection in the repair of articular cartilage lesions of the knee. Study Design: Systematic review. Methods: A systematic search was conducted in the databases EMBASE, MEDLINE, and the Cochrane collaboration. The retrieved articles were screened for relevance on title and abstract followed by a full-text study quality appraisal of the remaining articles. Eventually, a total of 4 randomized controlled trials were included. Results: Lesion size, activity level, and age were the influencing parameters for the outcome of articular cartilage repair surgery. Lesions greater than 2.5 cm2 should be treated with sophisticated techniques, such as autologous chondrocyte implantation or osteochondral autologous transplantation, while microfracture is a good first-line treatment option for smaller (<2.5 cm2) lesions. Patients who are active show better results after autologous chondrocyte implantation or osteochondral autologous transplantation when compared with microfracture. Younger patients (<30 years) seem to benefit more from any form of cartilage repair surgery compared with those over 30 years of age. Conclusion: Lesion size, activity level, and patient age are factors that should be considered in selecting treatment of articular cartilage lesions of the knee. In addition, these factors are a step toward evidence-based, instead of surgeonpreferred, treatment of articular cartilage lesions of the knee. Abstract As the understanding of interactions between articular cartilage and subchondral bone continues to evolve, increased attention is being directed at treatment options for the entire osteochondral unit, rather than focusing on the articular surface only. It is becoming apparent that without support from an intact subchondral bed, any treatment of the surface chondral lesion is likely to fail. This article reviews issues affecting the entire osteochondral unit, such as subchondral changes after marrow-stimulation techniques and meniscectomy or large osteochondral defects created by prosthetic resurfacing techniques. Also discussed are surgical techniques designed to address these issues, including the use of osteochondral allografts, autologous bone grafting, next generation cell-based implants, as well as strategies after failed subchondral repair and problems specific to the ankle joint. Lastly, since this area remains in constant evolution, the requirements for prospective studies needed to evaluate these emerging technologies will be reviewed.As the understanding of interactions between articular cartilage and subchondral bone continues to evolve, increased attention is being directed at treatment options for the entire osteochondral unit, rather than focusing on the articular surface only.

Power systems require modifications to the network's topology or isolation of major electrical equipment. These switching operations generate inrush currents and voltage disturbances on the electrical network that may affect the network stability, produce stresses on the power apparatus and accelerate the circuit breaker (CB) wearing. These transients and their negative consequences can be mitigated by control switching (CS). Furthermore, real-time circuit breaker monitoring allows power utilities to anticipate to an event and evaluate equipment performance.

Objective — to study the incidence and clinical and pathogenetic features of intestinal injury in patients with type 2 diabetes mellitus.
Materials and methods. Examinations involved 138 patients with type 2 diabetes mellitus (DM 2), aged from 39 to 67 years (mean age 53 ± 5 years), including 82 women (59 %) and 56 men (41 %). In addition to general clinical methods, investigations included plasma levels of the transforming growth factor‑b1 (TGF‑b1) and vascular endothelial growth factor (VEGF), the hydrogen breath test with lactulose, endoscopic examination of the intestine with biopsy followed by staining with hematoxylin‑eosin, immunohistochemical determining of claudin‑1 and VEGF, and conduction of PAS‑reaction.
Results. Diabetic enterocolopathy (DECP) was diagnosed in 72 (52.2 %) patients with DM 2. Clinical manifestations were nonspecific and similar to those of irritable bowel syndrome (IBS). It has been found that DECP correlates with the duration of the DM 2 course and was diagnosed more often in middle‑aged patients (52.1 ± 4.1 years). In patients with DECP, the increase in the proinflammatory cytokines TGF‑b1 and VEGF significantly exceeded those in IBS patients. Histologically the inflammatory cell infiltration in patients with DECP was more intense and diverse, there were signs of subatrophy of the glands with a relative decrease in the number of vacuoles in the goblet cells. The immunohistochemical study revealed that VEGF in the colon mucosa was visualized mainly in patients with DECP. Moreover, a tendency to a decrease in the claudin‑1 levels was established in these patients.
Conclusions. Intestinal damage was revealed in 67.4 % of patients with type 2 diabetes mellitus, and DECP was diagnosed in more than half of patients. Diabetic enterocolopathy had nonspecific clinical symptoms, required differential diagnosis with IBS, and was not always accompanied with abdominal pain. The presence of DECP more often correlated with the bacterial overgrowth syndrome, and levels of proinflammatory cytokines in the blood plasma and intestinal mucosa of these patients was raised.


The simulation model presented here describes dynamically the physico-chemical and control processes involved in refuse incineration plants. For this purpose there have been seven sectors identified and separated. Within these sectors transportation and reaction processes are calculated depending on the preceding state as well as random processes and control measures. This model enables to demonstrate the complete refuse incineration process starting at the input of refuse and ending at the output of slag and raw gas emissions including the steam production in the boiler. The model is useful to simulate, demonstrate and detailed analyse processes, dependences and operation characteristics. Accordingly this model can be helpful to M. Hälker et al.

The invention discloses a dual-feedback power supply clamp used for on-chip electrostatic discharge protection. The dual-feedback power supply clamp used for on-chip electrostatic discharge protection comprises an RC-triggered transistor feedback circuit between a VDD and a GND, wherein the feedback circuit comprises a P-type cascade transistor and an N-type cascade transistor and further comprises a resistor which is used for reducing the voltage of a big transistor when the circuit works normally; the feedback circuit is further provided with a filter potential point, an INV1OUT potential point, an INV2OUT potential point and a grid potential point. By using the dual-feedback power supply clamp provided by the invention, the P-type cascade transistor and the N-type cascade transistor are used to form the feedback circuit to effectively prolong the conduction time of the big transistor (Big FET(field effect transistor)) for electrostatic discharge (ESD) and current discharge, guarantee the complete release of electrostatic discharge pulses, inhibit the mistaken triggering of an electrostatic release protection circuit, and reduce the occupied area and electricity leakage of a power clamp circuit.


Context. Thanks to the cross-identification between the Gaia EDR3 (E-Data Release 3) catalogue and the quasars' compiled cata- logue LQAC-5 (Large Quasar Astrometric Catalogue-5), accurate astrometric parameters as well as photometric measurements were available for a set of 416113 quasars. Aims. After analysing the astrometric and photometric properties of these quasars,we concentrate our study on objects characterized by significant proper motion, which contradicts the postulate that they are fixed in the celestial sphere. Methods. We derived statistical properties of the positions, parallaxes, and proper motions of the quasars cross-matched with Gaia EDR3. We carried out a specific investigation of quasars with a proper motion larger than 10 masyr − 1 , and used colour–colour diagrams in mid-infrared to discriminate these quasars from stellar contamination. We discuss, in detail, a few cases where the abnormal proper motion could be caused by misidentifications. Results. We note that 43% of LQAC-5 quasars were not detected by Gaia EDR3, mainly because of the cut-o ff magnitude at G = 21. The comparison between r ( G ) ( Gaia ) and r (SDSS) shows a normal distribution. The normalized distributions of parallaxes and proper motions are identical to that of the Gaia CRF2, as well as the distribution of the G BP − G RP colour index. We have identified 937 LQAC-5 objects (0.27% of the sample) with Gaia EDR3 proper motion which is significant at the 5 σ level. We have clearly shown that below z = 0 . 35, the integrated magnitude G ( r ) obtained from SDSS spectra is smaller than G ( Gaia ), leading to the statement that the quasars are generally resolved under this threshold, which should lead to a bad determination of proper motion. Moreover, to discriminate quasars from stellar contamination, we have plotted them in a mid-infrared colour–colour diagram. Finally, we have made a final selection of 41 objects with µ > 10masyr − 1 , satisfying drastic constraints, which makes them potential candidates for considering their proper motion as real. Conclusions. In this paper we carried out a complete analysis of the quasars of the LQAC-5 which were cross-identified with Gaia EDR3 ; this serves as an alternative and complementary study with respect to Gaia CRF2, involving a di ff erent population of quasars. We selected a set of 41 quasars with a proper motion exceeding 10 masyr − 1 , which can be considered as very high for objects which are a priori fixed in the celestial sphere.


Abstract: One difficulty in grasping geopolitical terrorism carried out by the self proclaimed "State" claiming to be "Islamic" is the interwoven political, juridical and religious vision behind it and all the implications flowing from this. This article will attempt to identify some of the Juridical/Religious challenges posed by this phenomena and the diplomatic response of Pope Francis thereto.

The simultaneous improvement of radiating and scattering performance of an antenna is normally considered as a contradiction. In this paper, wideband gain enhancement and radar cross section (RCS) reduction are both achieved for a conventional patch antenna by loading metamaterial in an improved way. Through a detailed investigation of loading manners, the proposed patch antenna with both improved RCS and gain is proposed and experimentally validated. Both simulated and measured results show that, compared to the original antenna, the gain of the proposed antenna is enhanced almost over the whole operation band, and the wideband (in-band and out-of-band) RCS reduction is achieved concurrently.

The response of the Los Alamos atmospheric general circulation model to the smoke from the Kuwaiti oil fires set in 1991 is examined. The model has an interactive soot transport module that uses a Lagrangian tracer particle scheme. The statistical significance of the results is evaluated using a methodology based on the classic Student's t test. Among various estimated smoke emission rates and associated visible absorption coefficients, the worst- and best-case scenarios are selected. In each of the scenarios, an ensemble of 10 30-day June simulations are conducted with the smoke and are compared to the same 10 June simulations without the smoke. The results of the worst-case scenario show that a statistically significant wave train pattern propagates eastward-poleward downstream from the source. The signals favorably compare with the observed climate anomalies in summer 1991, albeit some possible El Nino-Southern Oscillation effects were involved in the actual climate. The results of the best-case (i.e., least-impact) scenario show that the significance is rather small but that its general pattern is quite similar to that in the worst-case scenario.


Rubber,polypropylene fiber and steel fiber were used by different combinations to reinforce the high strength concrete.The compressive strengths of reinforced concrete at room temperature and high temperature were tested.The effects of different combinations of three kinds of material on compressive strength and ductility of reinforced concrete at room temperature and high temperature were investigated. Test results show that the spalling resistance of high strength concrete is greatly improved by addition of hybrid material.


The thin-film dielectric response of organic films confined within a surface forces apparatus (SFA) and also between parallel sheets of atomically smooth mica is reported for the first time. Analysis is presented to infer dielectric properties of the organic film from the measured capacitance of the total system: sample, and mica sheets intervening between sample and electrodes. Measurements concerned the frequency dependence of normal-mode dielectric relaxation of cis-polyisoprene having dipoles aligned in the same direction along the chain backbone. We find that in thin-film geometries the peak frequency, fpeak, of normal mode dielectric loss (e″) is moderately lower than for bulk samples and that, more important, the expected terminal tail, observed in the bulk sample (e″∝f for f<fpeak), is not observed even at the lowest frequency examined. Thus the slow normal mode distribution is much broader and the terminal relaxation time is much longer for chains in the thin layers. These dielectric features are...


Changing global trends in the location of engineering consultancies are examined. This reveals the relative decline of firms headquartered in North America and the rise of European-based counterparts. It raises the question of why multinationals located in Asia, Africa, Latin America, and the Middle East have not broken into this Western club in greater numbers. Of particular interest is the relatively poor showing of consultancies based in Japan, Korea, and the Philippines—countries conspicuously successful in exporting construction contracting.

Direct pyrolysis of self-assembled polyacrylonitrile-block-polymethylmethacrylate (PAN-b-PMMA) diblock copolymer can be a promising route for fabricating an ordered carbon nanostructure. PAN-b-PMMA diblock copolymer was synthesized successfully by atom transfer radical (ATRP) polymerization in DMF at 90 °C with well-controlled molecular weight and narrow polydispersity. The resulting block copolymer self-assembled in the mixture of ethanol and water to form nanoparticles with a narrow size distribution. Furthermore, the high quality of the as-synthesized PAN-b-PMMA block copolymer experienced phase-separation to form a self-assembled nanostructure at 250 °C that was converted to a mesoporous carbon phase after heating at 800 °C. The pyrolyzed carbon product exhibited well-defined nanostructure with a high BET surface area of 860 m2 g−1 and an average mesopore size of 8.1 nm.
