Background The recurrence of colorectal cancer (CRC) is frequent within the first year of curative resection surgery and may be unavoidable. microRNAs have been suggested to play roles in carcinogenesis and cancer recurrence. We recently identified microRNA-29c (miRNA-29c) as a predictor of early recurrence in CRC. In the present study, we further investigated the functions and serum level of miRNA-29c in relation to early recurrence of CRC. Methods First we further confirmed overexpression of miRNA-29c in non-early relapse subjects. Gain-of-function in vitro studies were used to evaluate the effect of miRNA-29c on cell proliferation, migration, invasion, and cell cycle progression. The colon cancer cell line Caco2 and a stable clone overexpressing miRNA-29c were xenografted to evaluate the in vivo effect of miRNA-29c in null mice. Finally, circulating miRNA-29c was investigated as a potential biomarker for identifying early relapse. Results miRNA-29c expression significantly decreased during early relapse compared to non-early relapse in UICC stage II and III CRC patients (P = 0.021). In vitro studies showed that overexpression of miRNA-29c inhibited cell proliferation and migration. The cell cycle studies also revealed that miRNA-29c caused an accumulation of the G1 and G2 population. In vivo, miRNA-29c suppressed tumor growth in null mice. The serum miRNA-29c increased significantly in early relapsed patients compared to non-early elapsed patients (P = 0.012). Conclusions miRNA-29c shows anti-tumorigenesis activity, and preoperative circulating miRNA-29c levels can be used to predict postoperative early relapse of CRC.

This paper presents a 4-path LO generation system with automatic phase tuning for 60 GHz phased-array receivers. Each path employs a linear phase-shift generation chain composed of an injection-locked-oscillator-based phase shifter cascaded with an injection-locked frequency tripler. The frequency tripler with a proposed locking-range enhancement technique is employed to relax both the frequency and the phase shift of the phase shifter for high linearity and low power. Finally, a novel successive-approximation algorithm is proposed to perform automatic phase detection and tuning. Fabricated in a 65 nm CMOS process and occupying a core area of 1.4 ×2.0 mm2, the proposed 4-path LO generation system measures linear phase shift range larger than ±90°, amplitude variation within ±0.4 dB, phase resolution of 22.5°, and maximum phase errors of 22.0° and 1.5° before and after automatic phase calibration while drawing a current of 85 mA from a 1-V supply.


In this paper a hybrid multi-tanh bulk-driven input stage OTA for low total harmonic distortion (THD) biomedical Gm-C applications in weak inversion is presented. The proposed OTA was successfully simulated in an 130-nm IBM CMOS process. The simulations show an open loop gain of 46.4 dB and a unit gain frequency of 125 Hz with only 500 mV of power supply voltage and just 25 nW of power consumption. The transconductance is 24 nS with 300 mVpp of linear input range (HD3 ≤ - 60 dB), which is suitable for low-frequency and low-THD biomedical Gm-C applications.

This study investigates the dynamics of a short tethered satellite system composed of two satellites joined by a ten-meter tether. Despite the many studies in the literature regarding tethered satellites and their dynamics, none that specifically concern "short" tethers have been located to date. Equations of motion are derived and numerically integrated to produce the tether tension, system attitude, orbit, and libration characteristics. Techniques have been implemented which add corrections to the integrated states and help reduce longterm simulation errors. Also considered are the effects of perturbations due to the Earth's geopotential, solar and lunar gravity, aerodynamic drag and solar radiation pressure.


Shahnaz Qayumi Faculty of Early Childhood Education, Kwantlen University College P roblem Based Learning (PBL) is becoming more popular in medical circles. In the last few years, PBL formed the curricular foundation for many medical schools in North America. The interest in PBL now extends beyond the boundaries of North America to Europe, Asia, Central, and South America. Therefore it is essential to understand the theoretical basis of PBL and its connection to Piaget's pedagogical philosophy. The intention of this editorial is to introduce and brie y discuss Piagetian theory and its relation to the problem based learning methodology adapted in medical schools of North America. Jean Piaget was born on August 9, 1896, in the university town of Neuchatel, in Switzerland. From a young age, Piaget was dissatisŽ ed with many superŽ cial explanations of natural and social events. He wanted to Ž nd a scientiŽ c explanation for every thing that he found amusing. As young as 10 years of age, he became interested in scientiŽ c research. At this age he published an article about an albino sparrow, which he observed and studied in the park near his home. By age 21 he obtained his doctorate in the natural sciences. As a young graduate he started working in the Binet Laboratory in Paris. His job required him to construct a tool test to be used for the evaluation of children's intelligence. Although for this task he was asked to focus only on the correct answers provided by the children, Piaget was more curious and listened to their incorrect answers, as well. He found that the incorrect answers followed a strange and consistent pattern not demonstrated by the correct answers. Piaget believed that these patterns provide a clue to the way thought processes develop in children. In 1925, Piaget's Ž rst child, Jacqueline, was born. Piaget and his wife, Valentine Chatenay, observed and recorded every movement that Jacqueline made from infancy, and later with their other two babies, Lucienne and Laurent. The Ž ndings he obtained from the observation of his children and other children served as a turning point in his future career. He was the Ž rst to study children's thinking, and created a comprehensive theory of cognitive development. In the development of his theory, Piaget Ž rst observed, listened, and studied children's thinking in their spontaneous activities. He then combined


In this paper, we determine the general solution of the quartic equation f(x+2y)+f(xi2y)+6f(x) = 4(f(x+y)+f(xiy)+ 6f(y)) for all x;y 2R without assuming any regularity conditions on the unknown function f. The method used for solving this quartic functional equation is elementary but exploits an important result due to M. Hosszu (3). The solution of this functional equation is also determined in certain commutative groups using two important results due to L. Szekelyhidi (5).


We analyze the causes of severe floods in the Yangtse and Nenjiang River basins in summer of 1998 from the viewpoint of the interaction between components of the earth system based on earthquake, soil temperature, and precipitation data. The role of thermal activities of the solid earth in stimulating torrential rain is investigated in detail. The results show that the precipitation distribution agrees well with the soil temperature anomaly field and activities in the solid sphere of the earth system may excite and control the behaviors of the atmosphere. Mechanisms that how the soil temperature field exerts its influence on precipitation field are also discussed.


In this paper we give a new denition of the positive-deniteness of the Liapunov functional involved in the stability and asymptotic stability investigation. Using this notion we prove Liapunov type theorems and apply these results to the scalar equation _ x(t) = b(t)x(t r(t)), where b(t) and r(t) may be unbounded.


Effective mosquito surveillance and control relies on rapid and accurate identification of mosquito vectors and confounding sympatric species. As adoption of modified mosquito (MM) control techniques has increased, the value of monitoring the success of interventions has gained recognition and has pushed the field away from traditional 'spray and pray' approaches. Field evaluation and monitoring of MM control techniques that target specific species require massive volumes of surveillance data involving species-level identifications. However, traditional surveillance methods remain time and labor-intensive, requiring highly trained, experienced personnel. Health districts often lack the resources needed to collect essential data, and conventional entomological species identification involves a significant learning curve to produce consistent high accuracy data. These needs led us to develop MosID: a device that allows for high-accuracy mosquito species identification to enhance capability and capacity of mosquito surveillance programs. The device features high-resolution optics and enables batch image capture and species identification of mosquito specimens using computer vision. While development is ongoing, we share an update on key metrics of the MosID system. The identification algorithm, tested internally across 16 species, achieved 98.4 ± 0.6% % macro F1-score on a dataset of known species, unknown species used in training, and species reserved for testing (species, specimens respectively: 12, 1302; 12, 603; 7, 222). Preliminary user testing showed specimens were processed with MosID at a rate ranging from 181-600 specimens per hour. We also discuss other metrics within technical scope, such as mosquito sex and fluorescence detection, that may further support MM programs.


This paper will discuss the use of the human subsystem in development phases of human space flight. Any space mission has clearly defined subsystems, managed by experts attached to these. Clearly defined subsystems and correct use provide easier and more efficient development for each independent subsystem and for the relation between these subsystems. Furthermore, this paper will argue that a defined subsystem related to humans in space has not always been clearly present, and that correct implementation is perhaps missing, based on experience and survey data. Finally, the authors will discuss why the human subsystem has not been fully integrated, why it must be a mandatory part of the programming, a redefinition of the human subsystem, and suggestions of methods to improve the integration of human factors in the development.


This study provides the first empirical evidence on the effects of intellectual property rights (IPRs) protection on bilateral intra-industry trade (IIT) flows. The empirical investigation is based on pooled South African data and takes advantage of the theoretical distinction between horizontal and vertical IIT. A gravity equation of international trade is estimated in the context of fixed and random effects models. The principal findings suggest that IPRs and imitation abilities separately are not important factors in determining IIT flows. However, the interaction between them is important.


Packet scale rate guarantee (PSRG) is a service guarantee defined recently for expedited forwarding (EF) service under the differentiated services framework. In the original work of PSRG [J.C.R. Bennett et al., August 2002], two classes of schedulers are proved to be PSRG servers. In addition, it is proved that end-to-end PSRG and consequently end-to-end delay bound are provided by a network of PSRG servers implementing per-flow scheduling. Moreover, a delay bound is presented for a network of PSRG servers implementing aggregate scheduling. In this paper, we show that these results can be improved for networks of PSRG servers of these schedulers. In particular, we show that the two classes of schedulers belong to a common scheduler family. In addition, we prove that the end-to-end delay bounds can be improved for networks of such schedulers. We also prove that PSRG can be derived from the delay bound and call this PSRG-from-delay-bound property. Moreover, with this property, we derive and discuss end-to-end PSRG for both the per-flow scheduling network and the aggregate scheduling network.

To improve the yield of β-glucanase by Bacillus amyloliquefaciens 5582, the fermentation techniques were optimized in laboratory. In a 5L fermentor, the optimal fermentation conditions were: 60% medium volume, 6.67% inoculum, 18 h-cultured seed, aeration 1.0 L/(L·min), stirring at 500 r/min, initial temperature of 36℃. The fermentation temperature was decreased to 32℃ after 27h cultivation and kept to the end of fermentation. The β-glucanase activity was 182.52 U/ml at 51.75 h, which was 28 % higher than that in constant-temperature fermentation.

Background Generalized anxiety disorder (GAD) is a prevalent anxiety disorder, with cognitive behavioral therapy (CBT) being the gold standard treatment. However, it is inaccessible and costly to many, as the mental health industry is overwhelmed by the demand for treatment. This means effective, accessible, and time-saving strategies must be developed to combat these problems. Web-based interventions for mental health disorders are an innovative and promising way to address these barriers. While electronically delivered CBT (e-CBT) has already proved productive and scalable for treating anxiety, other less resource-intensive interventions can be innovated. Checking up on mental health face-to-face has been shown to provide similar benefits to patients with anxiety disorders previously, but more research is needed to evaluate the efficacy of web-based delivery of this intervention. Objective This study will compare the efficacy of e-CBT and a web-based mental health check-in program to treat GAD. These programs will both be delivered through a secure, web-based care delivery platform. Methods We will randomly allocate participants (N=100) who are 18 years or older with a confirmed diagnosis of GAD to either an e-CBT program or a mental health check-in program over 12 weeks to address their anxiety symptoms. Participants in the e-CBT arm will complete predesigned modules and homework assignments while receiving personalized feedback and asynchronous interaction with a therapist through the platform. Participants in the mental health check-in arm will be contacted weekly through the web-based platform's written chat feature (messaging system). Therapists will ask the participants a series of predesigned questions that revolve around a different theme each week to prompt conversation. Using clinically validated questionnaires, the efficacy of the e-CBT arm will be compared to the mental health check-in arm. These questionnaires will be completed at baseline, week 6, and week 12. Results The study received ethics approval in April 2021, and participant recruitment began in May 2021. Participant recruitment has been conducted through targeted advertisements and physician referrals. Complete data collection and analysis are expected to conclude by August 2023. Linear and binomial regression (continuous and categorical outcomes, respectively) will be conducted. Conclusions To the research team's knowledge, this will be the first study to date comparing the efficacy of e-CBT with a web-based mental health check-in program to treat GAD. The findings from this study can help progress the development of more scalable, accessible, and efficacious mental health treatments.

A flexible technique has been developed to analyze small size finite arrays by means of the finite array periodic Green's function. It attempts to improve the accuracy of the results by iteratively re-defining a better window function. Using a relatively simple structure, these methods have demonstrated that the behavior of the active impedance of each element in a finite array can be approximated with limited success by the model. These methods may be useful for prototype modelling of more complicated microstrip structures in which the full analysis method would require prohibitively large computing resources.

Administering antigestagenic or luteolytic
 substances to the mismated bitch frequently results in death and resorption
 of the majority of the conceptus but not of all, if the treatment is not
 repeated or prolonged. Only little is known about the local processes taking
 place in spontaneous and induced embryonic/fetal death in canine pregnancy.
 Morphological studies are still missing. In an orientation study eight Beagle bitches were examined in two
 consecutive pregnancies. Two bitches (K I, K II; group K) served as controls,
 while three bitches (A I, A II, A III; group A) were administered
 Aglepristone (10 mg/kg s.c.) at
 day 24 and 25 after ovulation (p.ov.) and three bitches (C I, C II ,C III;
 group C) received cloprostenol (1µg/kg s.c. at day 24 and 27 p.ov.) in
 combination with the dopamine-agonist cabergoline (5µg/kg p.o. from day 24
 p.ov. to day 30 p.ov.). If the pregnancies were not terminated until day 36
 (1st gestation) or until day 31 (2nd gestation)
 treatment were repeated until the last conceptus died or until ovariohysterectomy, respectively. As the bitch C II suffered from an
 endometritis after the 1st pregnancy she had to be replaced by
 bitch C III. Therefore, C III passed only the 2nd gestation. The ultrasonographic features of the conceptuses
 and the embryonic/fetal heart rate were examined every day using real-time
 ultrasonography. The perfusion of individual placental sites was measured
 every other day by Doppler ultrasonography until the last fetus died.
 Furthermore the concentrations of oesteradiol-17s (E2),
 progesterone (P4) and relaxin (RLX) were
 determined in peripheral blood serum. During the 2nd pregnancy the examinations were performed
 until ovariohysterectomy between day 30 and 34
 after ovulation (p.ov.), when some of the fetuses were already dead. The
 control dogs were ovariohysterectomized at
 corresponding days. The hormone analysis revealed normal E2 concentrations in
 all bitches and physiological P4 and RLX patterns in the control
 group. In the control bitch K II two spontaneous resorptions occurred during
 the 1st (day 24 and 33 p.ov.) and three during the 2nd
 pregnancy (day 21, 24 and 28 p.ov.). Under Aglepristone treatment the peripheral P4 and RLX
 concentrations did not differ from those of the control group before
 pregnancies were definitely terminated. Thereafter both hormones showed a
 marked decline. Death of the first embryo occurred 2 to 4 days after the
 first aglepristone administration. Termination of the first pregnancies was
 completed between 15 and 17 days after the initial aglepristone injections.
 The cloprostenol/cabergoline treated dogs showed a sharp drop of P4
 concentrations one day after the start of medication and a further decrease
 during the treatment period. However, P4 levels were not suppressed
 to < 2 ng/ml by the basal medication. During the 2nd pregnancy
 P4 concentrations of < 2 ng/kg were measured after repeated
 medication in both dogs at the day of ovariohysterectomy.
 The decrease of P4 was followed by death of the first embryo/fetus
 between day 3 and 8 of treatment. In both bitches the first pregnancy was
 terminated 13 days after start of treatment (day 37 p.ov.). After death of
 the last conceptus the peripheral RLX concentrations dropped sharply in the
 last third of pregnancy.
 Average embryonic heart rate in the pretreatment period (days 21 to 24
 p.ov.) was 192 b.p.m. (beats per minute) in all groups. In mid-pregnancy (day
 29 to 31 p.ov) the mean embryonic/fetal heart rate reached a plateau of about
 234 b.p.m. without showing any influence of either medication. In three
 fetuses a dramatic reduction of the heart rate was detected maximally 2 hours before the death. In the control group a reduction of the
 mean heart rate to 212 b.p.m. was noted in the prepartum
 period (day 61 p.ov.). The blood flow velocities in the uterine arteries measured in the
 neighbourhood of the intact placental sites increased gradually throughout
 physiological pregnancy in both bitches of group K. The aglepristone
 treatment led to a significant decrease of the time average maximum velocity
 (TAMAX) at the days 25/27 p.ov. and of the S/D-ratio
 at days 29/31 p.ov.. The pulsatility index, the resistance index and the
 A/B-ratio in the bitches in the group C was significantly lower than
 in the control group before (at days 21/23 p.ov.) and after the start of
 cloprostenol/cabergoline treatment (at days 25/27 p.ov.). The S/D-ratio was
 also significantly decreased at days 25/27 p.ov. and
 at days 29/31 p.ov. a significant decrease of all
 blood flow velocities (SPV, DPV, EDV, TAMAX) was observed. In the placental sites of the intact conceptuses
 of groups A and C no macroscopic or microscopic signs of
 placental distress and no sings of the treatment mechanisms could be
 identified. No morphological differences were observed between the
 spontaneous (bitch K II) and induced resorptions (group A and C).
 After embryonic/fetal death the placental labyrinth was completely
 disintegrated. Signs of resorption like an increased macrophage infiltration
 in the maternal stroma were absent. The vaginal discharge observed in all bitches of groups A and
 C in the 1st pregnancy macroscopically corresponded to the
 fluid masses found in the resorption sites after ovariohysterectomy.


aginal administration of hormones, contraceptive or replacement hormone therapy, is rising in market popularity. The vaginal ring, or NuvaRing (Organon USA Inc, Roseland, NJ), is estimated to have more than 1 million users in more than 25 countries, including the United States and Canada. The NuvaRing is a flexible combination contraceptive vaginal ring containing 2 active ingredients: a progestin, etonogestrel, and an estrogen, ethinylestradiol. It is a nonbiodegradable flexible transparent latex-free device with an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. It can easily be compressed to 1 cm or less for self-insertion into the vagina. The ring releases 15 μg of ethinylestradiol and 120 μg of etonogestrel per day and inhibits ovulation.1 The advantages over oral contraceptives include avoidance of first-pass metabolism through the liver, constant serum steroid levels, and simple selfinsertion by the user. It is inserted once every 28 days, left in place for 21 days, and then removed for a 7-day break, during which time withdrawal bleeding takes place . There is an extensive published list of potential adverse reactions predominantly relating to the effects of hormone administration, such as increased risk of thromboembolism, stroke, myocardial infarction, high blood pressure, cancer of the reproductive organs and breast, gallbladder disease, liver tumors, and lipid metabolism defects. Expulsion may occur while removing a tampon, during intercourse, or with straining. Inadvertent placement of the NuvaRing is not a well-recognized or anticipated complication. One case report has been published describing incorrect placement of the NuvaRing into the bladder and subsequent recurrent cystitis.2 We report a second case with a description of the urological technique required for removal. Inadvertent bladder placement of the NuvaRing, although rare, should be considered a potential complication in patients who have "lost" the NuvaRing and have recurrent urinary tract infections.


This study presented an optimization of the suitability of medium-K basaltic andesite pumice and scoria as coarse aggregates on structural lightweight concrete. The testing results indicated that these pumice and scoria had a typical characteristic so that they were completely different from those existed previously. Both typical vesicular rocks also fulfilled the requirements of coarse lightweight aggregate. The mix designs of structural lightweight concrete for the specified compressive strengths yielded Portland-Pozzolan Cement (PPC) contents were relatively lower than the previous studies conducted. The property of fresh concrete tests showed that for the specified slump values, the lightweight concrete mixtures can achieved satisfactory workabilities. While the properties of hardened concrete tests showed that almost all equilbrium densities fulfilled the requirements, but three equilibrium densities of scoria lightweight concrete were slightly greater than the requirements so that they were classified as structural semi-lightweight concretes. In addition, the use of typical pumice and scoria as coarse aggregates on that concrete yielded a significant density reduction, ie. approximately 20 %. The compressive strength obtained in the tests conducted can achieved those specified in the mix designs however two pumice structural lightweight concretes did not achieve them. The ultimate strains and modulus of elasticities also remained in proportional values, while the splitting tensile strengths and modulus of ruptures were relatively low when compared with previous studies.

Power systems are the typical cyber-physical systems in which the closed-loop hierarchical control systems (HCSs) are widely used to ensure their stable and safe operation. To describe the coupling operation mechanism of an HCS and power grid by expanding current steady-state power flow analysis theory, we propose an information-energy flow model and develop a matrix-based computational approach. With the help of the methods, we can directly calculate the mutual influence of the cyber and physical parts. Since the mechanism of power flow computation is mature, we focus on the cyber side, proposing an information-flow-oriented network model as well as a matrix-based computation method for its information flow. In particular, we develop a minimum-cut-set-based partition and equivalence method to address a complex cyber network with non-linearity issues associated with data processing. Subsequently, we discuss cyber-physical sensitivity and vulnerability issues. In the case study, we calculate the information-energy flow of an IEEE 14-node system with real time-voltage stability monitoring and control application and compare the results with simulation results. The similarity of the results between the two methods verifies the effectiveness of our approach.


Heat transfer characteristics associated with steam/air mixtures were studied in two pilot scale batch type steam/air retorts: a vertical positive flow retort and a horizontal forced circulation Lagarde retort. A method employing
transient heat conduction into rectangular bricks of aluminum and stainless steel was developed to evaluate the surface heat transfer coefficient
(h) of steam/air mixtures. A system was designed to facilitate an instantaneous
drop of the test brick, from an insulated box inside the retort, into a specified steam/air medium after the come-up period. The influences of steam content, temperature, flow rate and flow direction of the heating medium and orientation of test bricks on the associated h values, temperature
distribution and pressure stability in the retorts were studied. In addition,
thermal processing efficacy was evaluated by measuring the rate of heat penetration into bricks of silicone rubber and rigid nylon which have thermal diffusivities in the range common for foods.
In both retorts, steam content (S) of the mixture was found to be the major factor influencing h (p<0.05); however, temperature had no significant
effect (p>0.05). Further, the flow direction and flow rate of the heating
media in the positive flow retort, and brick orientation in the Lagarde retort also influenced h (p<0.05). The general relationship between h and S was exponential: h = a exp(bS). In the positive flow retort with the test brick in the vertical orientation, the values of a and b were 153 W/m²C and 0.0421 respectively, for steam/air media flowing in an upward direction,
and were 337 W/m²C and 0.0355 respectively, for the media flowing
downward. The surface heat transfer coefficient was also found to increase linearly with the medium flow rate. With the Lagarde retort,

steam/air flow was always horizontal and flow rate was not adjustable. In this case, h was influenced by the test brick orientation. For bricks in the vertical orientation, the exponential parameters, a and b, were 1011 W/m²c and 0.0226 respectively, whereas in the horizontal orientation, these
were 1669 W/m²C and 0.0132
Temperature distribution studies in the positive flow retort indicated that the overall standard deviation of the medium temperature at several locations
during the cook period (excluding come-up) increased (p<0.05) with a decrease in the steam content and flow rate of the heating media. The effects
of temperature and flow direction were nonsignificant (p>0.05). In the Lagarde retort, the temperature distribution was not influenced either by steam content or temperature of the steam/air medium. Pressure stability studies indicated that the air content and temperature of the medium increased
(p<0.05) the standard deviations of retort pressure during the cook period. Based on the temperature and pressure deviations in the two retorts,
steam/air mixtures with 86-90% steam contents were considered to provide
satisfactory overriding air pressures for processing of retort pouches at 105-120°C.

Gallman and Taylor take up murder at the boundary zones between the Iroquois and British settlers and between Spanish Florida and the Lower Creeks and Seminoles. Despite contrasts between the legal systems of the empires—civil law and inquisitorial procedure on the Spanish side, common law and trial by jury on the British side—indigenous groups came to similar conclusions regarding murder. Specifically, Native leaders rejected execution of the guilty, as proposed by English law, or other punishments, from execution to imprisonment to exile, under Spanish law. They opted instead to resolve matters by "covering the grave," or giving gifts by the culpable party to the aggrieved party in lieu of revenge. This practice was less likely to spark a blood feud and enabled indigenous groups to preserve corporate autonomy in the face of pressures to conform to imperial norms. Though reluctantly, imperial officials often went along with this in order to keep the peace.


Birth is a physiological process that represents the start of life as a physically separate individual. It signifies a transitional phase that every new-born undergoes, thus leaving the highly protected intrauterine environment to independent existence. 1,2 Successful transition from fetal to neonatal life comprises diverse physiological modifications. Before birth, the baby receives oxygen and removes carbon dioxide through the placenta, while after birth, lungs take over this function. The modulation from placenta to lungs for gas exchange begins when the umbilical cord iscut or tied off and the baby takes its first breath. 3 Approximately 5% ABSTRACT


The aim of this study was to investigate the effects of high oxygen modified atmosphere packaging on the quality of fresh-cut lettuce during storage. The lettuce slices were packaged in boxes filled with 60% O2 + 20% CO2 + 20% N2 and 100% O2 at 4 ℃ for 14 days, in contrast to that of air treatment. The results showed that the qualities of fresh-cut lettuce were significantly affected by high oxygen modified atmosphere packaging. Packaging with 60% O2 + 20% CO2 + 20% N2 and 100% O2 inhibited the loss of weight, formation of cellulose and the loss of vitamin C as well as chlorophyll. In addtion, the qualities of fresh-cut lettuce were kept better under 100% O2.

Source of material The synthesis of the title compound have been described previously [1] as a part of our research program focused on serotonin 5HTIA receptor ligands. The crystals for X-ray studies were obtained from ethanol / acetone (1:1) mixture by slow evaporation. However most of the obtained samples have been classified as plates of amorphous glass and were not appropriate for measurement on single-crystal difiractometer. The crystals selected for this study were small and difficult to handled, because the material was soft. Discussion As a subsequent part in our researches on the 5HTIA and 5HT2A receptors ligands modifications we have investigated the crystal structure of the title compound. The compound is closely connected to a lately reported structure [1]. The independent unit of the crystal consist of the protonated main molecule, Cl~ anion and two water molecules. As previously found [1-4], the main molecule under discussion incorporates tetrahydroisoquinoline and cyclohexane two cyclic moieties linked via a six-atoms spacer constitutied by four carbons and amide group. As it was expected the heterocyclic ring of tetrahydroisoquinoline adopts half chair conformation. The spacer and hydrogen adopt equatorial and axial positions at Ν11, respectively. In the molecule both hydrogens bonded to N-atoms are the same side of the spacer having almost Crystal: Wavelength: μ· Difiractometer, scan mode: 20max: N(hk¡)masuná, N(hkl)urúque'· Criterion for /obs, N(hkl)p.

The author argues that the concept of justification is viewed best through elucidation of the processes of ethical and epistemic justification, with specific attention paid to what has been dubbed the "internalist/externalist" distinction in such justification. The first part of the argument clarifies the nature of the distinction as it occurs in ethics and then epistemic justification, noting that there is a parallel between the uses of the distinction, but that it is the way in which the uses are not parallel that is most salient for conceptual purposes. The author then claims that there is an analogous distinction, frequently made in ethical justification, and that is the alleged normative/descriptive distinction. A look at the intersection of that distinction with the internalist/externalist juncture yields the notion that epistemic justification, in particular, could benefit from an externalist/ descriptive approach. Finally, the author argues that we would do well to apply some of the work of the social sciences to epistemic justification theory. The author concludes that the concept of justification includes all four components (internalist, externalist, nor mative, and descriptive) and that clarification of justification simpliciter involves an examination of justification in its various modes.

Opponents of abortion in the United States have long made strategic comparisons between abortion and slavery to advance their movement. Within the past two decades, a White‐led branch of the American "pro‐life" movement began invoking racial categories and movements for racial justice to advocate for the socio‐legal recognition of frozen embryos as persons. Extending from ethnographic research with proponents of "embryo personhood," this article examines three examples of personhood advocacy—a lawsuit, promotional video, and legislative bill—that instrumentalize race through strategic comparisons between embryos and Black Americans, and personhood advocates and racial justice leaders. More than misleading comparisons, invoking race in personhood advocacy underscores this radical movement's threat to reproductive and racial justice. Antiabortion politics of recognition present another durable link between racial and reproductive politics in the United States.


Objective: To summary the genotyping,clinical manifestations,diagnosis and clinical treatment of eosinophil gastroenteritis( EG). Methods: One EG child with recurrent gastrointestinal symptoms,excluding parasitic infections,blood system cancer and other diseases,was dignosed by examination,who was treated with anti-allergic drugs,leukotriene inhibitor and corticosteroid. The time of clinical symptoms remission and disappear,and laboratory index recovery were observed. Results: The recurrent vomiting,abdominal pain,diarrhea and other gastrointestinal symptoms,even dysphagia,intestinal obstruction and intestinal perforation,were the clinical features of EG. The laboratory test showed that eosinophilia granulocyte of peripheral blood increased. The rough mucosal congestion and edema,and point flake erythema or erosion were found by endoscopic examination. Fifteen to twenty eosinophils per high power field of the lesion were identified by pathology examination. The laboratory parameters returned to normal level,and clinical symptoms improved or disappeared after treatment. Conclusions: EG is a gastrointestinal allergic benign disease,the effect of which treated with corticosteroid is effective.

This thesis defines the Pakistan's diplomatic policy as "foreign policy of small states," and chooses the theory of foreign policy of small states to analyze and elucidate Pakistan's foreign policy behaviors. Pakistan, given her geopolitical importance, occupies a crucial position in South Asia. Yet as a small state, when dealing with neighboring big states such as China and India, she has to put all international factors into consideration and keep making adjustment along with time as well. Sometimes small state would use her relations with big state as leverage to obtain diplomatic gains; sometimes the tail small states also wag the dog big states. This makes the study of small state foreign policy an interesting one. Analyzing Pakistan-China relations from the Pakistani angle rather than from the Chinese perspective therefore provided us with a new deep insight. This thesis is divided into three parts: The first part is about Pakistan's foreign policy in general and her policy toward China in particular. Pakistan's foreign policy environment and the changes and continuities in her foreign policy were discussed. Part two is the answer to the research topics, and the third part is final reflection on the theories of small state foreign policies. This thesis concludes that Pakistan's policy toward China not only satisfied her domestic needs for economic developments, but also provided here with some diplomatic leverages to uplift her international status. It is a successful foreign policy.


Critical theory, as conceived by Theodor Adorno and Max Horkheimer, distinguishes itself from "traditional" theory by claiming to be a theory with "practical intent." In this regard, it finds its inspiration in Marx's famous Eleventh Thesis: "The philosophers have only interpreted the world, in various ways; the point, however, is to change it."' Contemporary critical theory, in the work of Jurgen Habermas, similarly draws its inspiration from the Marxian imperative to change the world, but interprets its task as the identification and clarification of the "necessary conditions" for emancipated living. These "necessary conditions" are grounded in a formal, procedural conception of rationality that leaves questions of substantive content to be determined by the participants themselves. While many have thought that Habermas has been mistaken to be so restrictive in the range of issues he allows for theory, his perspective is democratic in that it discourages theorists from making unwarranted claims to knowledge and aims to establish a basis for full and equal participation in community decision-making. He is certainly not indifferent to the "others" who have been excluded from the discourses of modernity, and his theory2 is an attempt to elucidate the ethical-political discourses in which the disinherited of the modem world can press to have their views discussed and their claims to rightness redeemed. Nonetheless, and despite these democratic aims, contemporary critical theory, in its Habermasian formulation, has seemed to many to be curiously disengaged from the world, and it is with some concern that the theory's proponents see the disinherited of modernity-variously defined as women, Blacks, gays, lesbians, native peoples, prisoners-finding their aspirations reflected in the increasing number of postmodern theories heavily influenced by genealogy and deconstruction. Recent critical theory, viewed from the standpoint of claims to have a practical intent and action orientation, is understandably on the defensive. For what is the point of wanting to effect fundamental social and political change, if those whose interest it is supposed to be to have such change do not see themselves addressed in the theory? In the last few years several adherents of critical theory have suggested that the opposition between modernity and postmodernity-an opposition fostered on both sides of the modern/postmodern divide-is overdrawn, unproductive, and unnecessary, and there have been attempts by some to accommodate postmodern concerns by mediating between critical theory and the newer critiques. My essay begins by discussing two such efforts, those of Richard Bernstein and Thomas McCarthy.4 There are important differences between these two writers, but each seeks to regain some of the ground lost to postmodernism by arguing that the reconstructive project of critical theory is a necessary corrective to limitations in the newer methodologies and remains "on course" to succeed, especially as regards its ability to deliver on the idea of a practical intent. After discussing the argument provided by Bernstein and McCarthy, I offer an alternative assessment of what is at issue between critical theory and postmodernism by turning to the question of gender. I conclude by resituating the problem of critical theory's supposed disengagement from the world. Bernstein tells us that his book, The New Constellation, arose out of suggestions that he "take on" Heidegger and the French. The more closely he examined the two poles of modernity and postmodernity, the more convinced he became that our modern/postmodern condition has to be understood as arising out of a "new constellation" of social and political forces and as calling for a new understanding of how we should live in the world. The ethical-political question is the dominant motif in Bernstein's book and he formulates it as follows: "critique in the name of what?" or "what are we affirming and why are we affirming it when we engage in critique? …


Young planets interact with their parent gas disks through tidal torques. An imbalance between inner and outer torques causes bodies of mass ≳0.1 Earth masses (M⊕) to lose angular momentum and migrate inward rapidly relative to the disk; this is known as "Type I" migration. However, protoplanets that grow to gas-giant mass, O(102) M⊕, open a gap in the disk and are subsequently constrained to migrate more slowly, locked into the disk's viscous evolution in what is called "Type II" migration. In a young planetary system, both Type I and Type II bodies likely coexist; if so, differential migration ought to result in close encounters when the former originate on orbits exterior to the latter. We investigate the resulting dynamics, using two different numerical approaches: an N-body code with dissipative forces added to simulate the effect of the gas disk, and a hybrid code that combines an N-body component with a one-dimensional viscous disk model, treating planet-disk interactions in a more self-consistent manner. In both cases, we find that sub-gap-opening bodies have a high likelihood of being resonantly captured when they encounter a gap-opening body. A giant planet thus tends to act as a barrier in a protoplanetary disk, collecting smaller protoplanets outside of its orbit. Such behavior has two important implications for giant planet formation. First, for captured protoplanets it mitigates the problem of the migration timescale becoming shorter than the growth timescale when Mproto ≳ 1 M⊕. Second, it suggests one path to forming systems with multiple giant planets: once the first has formed, it traps (or indeed accretes) the future solid core of the second in an exterior mean-motion resonance, and so on. The most critical step in giant planet formation may thus be the formation of the very first one.


ZigBee is an international standard for low-power and low-data rate WPAN. ZigBee works on IEEE 802.15.4 MAC and physical layers. Its network layer is liable to facilitate routing in networks. To provide a near optimal routing path as well as to balance the load and energy over the nodes, Energy-efficient shortcut tree routing (ESTR) protocol suggested an optimization method with three criteria such as minimum hop-counts, minimum congestion and maximum link quality. This paper proposes an Energy potent shortcut tree routing (EPSTR) that adds one more criterion called minimum failure-transmissions with EPSTR's criteria. The values for these criteria can be derived from the neighbor table data of a node. Performance evaluation reveals that EPSTR appreciably expands the network lifetime and shows better routing performances compared to ESTR.

In order to study the impact of nucleus accumbens-1 (NAC1) expression on survival in cancer cell and the molecular mechanism involved. NAC1 has been observed to be up-regulated in human cancer, and to play an important role in progression and recurrence of ovarian cancer. In this study, we investigated the regulatory role of NAC1 in glycolysis and the effect of the NAC1-mediated glycolysis on cancer cell survival. Cell biology, molecular biology, and pharmacology approaches and methods were used in this study. We demonstrated: 1) NAC1 is a critical regulator of cancer cell survival under hypoxic condition. Silencing of NAC1 leads to increase in the cleaved caspase-3 and cleaved PARP, and a decline in cell viability and colony formation when the cells were subjected to hypoxia; 2) NAC1 is a novel regulator of glycolysis. Depletion of NAC1 leads to an increase in the concentration of glucose in the culture medium, a decrease in the level of intercellular lactate; 3) NAC1 enhances the stability and protein level of HIF1α. Under hypoxia, NAC1 promotes cancer cell survival and glycolysis through strengthening the stability of HIF-1α.

Karst watersheds with significant losing streams represent a particularly vulnerable setting for ground water contamination because of the direct connection to surface water. Improvement of water quality in this type of karst setting faces many of the same management challenges as typical surface watersheds with regards to implementation of best management practices and responsible development in urbanizing areas. Because of the existing agricultural land-use and future threat of heavy urbanization, two losing stream karst basins were chosen for intensive monitoring in Boone County, Missouri: Hunters Cave and Devils Icebox Cave. Land use within both watersheds is similar with nearly equal percentages of row-crops, grasslands, and forest. Year-round monitoring was initiated in April 1999 with the objective of characterizing the water quality status of the main cave streams relative to herbicide, nutrient, and coliform bacterial contamination. Water sampling for contaminants entails grab samples at regular intervals and runoff event sampling using automated sampling equipment. In the first year, at least one herbicide or metabolite was detected in 60% of Hunters Cave samples and 72% of Devils Icebox samples. Total and inorganic nitrogen and phosphorus concentrations were generally much higher than existing Environmental Protection Agency guidelines for nutrient contamination of streams. Fecal coliform bacteria levels were generally above the whole body contact standard (200 cfu/100 ml -1 ) in the Icebox, regardless of flow conditions. Under runoff conditions, fecal coliform levels in both caves can exceed 10,000 cfu/100 ml -1 . Prevailing land management has significantly degraded the water quality in both watersheds.


This research was designed to reveal: students' speaking anxiety level,
dominant aspect causing speaking anxiety, and dominant strategy in coping
students' speaking anxiety. The method of this research was descriptive survey
which was done on the sixth semesters of English Department, Muhamadiyah
University of Purwokerto, on academic year 2013/2014. The samples were 25
students or 20% from the population. Data was collected through questionnaires
and interview. The first questionnaire was adapted from Horwitz, Horwitz, and
Cope (1986) namely Foreign Language Classroom Anxiety Scale (FLCAS). It
was made for knowing students' level of speaking anxiety and dominant aspect of
anxiety that made students experienced speaking anxiety. The second
questionnaire was adopted from Rasmodjo (2011). It was for knowing strategy
that students used in coping their anxiety. The finding of the questionnaires
revealed that students experienced speaking anxiety in severe level (56%),
moderate level (36%), and mild level (8%). Fear of negative evaluation became
dominant aspect (65.28%) causing speaking anxiety. It followed by test anxiety
(58.96%) and communication apprehension (56.72%). In coping students'
speaking anxiety, it was found that making good preparation (belonged to
memory strategy) was used by 80% students. Interview result also revealed the
same point that students were in speaking anxiety, exactly in severe level. Fear
negative evaluation became the dominant aspect causing speaking anxiety
(62.5%) and most of them asserted that making good preparation became their
strategy in coping speaking anxiety (62.5%).


In this report, on the basis of the difference in lymphocytic make-up, the lymphatic tissue of the tonsilla caecalis was divided into two parts, the mid and deep portion of the lamina propria and its superficial portion which was referred to as a subepithelial zone. In the former there were accumulated small lymphocytes, while in the latter lymphocytes in various sizes, small to large, and cells of plasmocytic series. The germinal centers always appeared in the mid and deep portion and never in the subepithelial zone. Chickens which were bursectomized and X-irradiated at hatching showed a marked depletion of lymphocytes in the subepithelial zone while an increasing accumulation of small lymphocytes was persistent in the mid and deep portion. On the other hand, in chickens which received repeated X-irradiation of the thymus, lymphocyte depletion was striking in the mid and deep portion but not in the subepithelial zone. In both groups of treated chickens the germinal centers were markedly decreased in number or essentially lacking. In the bursectomized-irradiated chickens, foci of reticular cell aggregation usually occurred in the mid and deep portion and were deemed as an incomplete form of the germinal center. It was concluded that in the tonsilla caecalis the bursa-dependent area was the subepithelial zone and the thymus-dependent area was the mid and deep portion of the lamina propria, Possible relation to the germinal center development of three factors, i.e. the formation of the focus of reticular cell aggregation in the thymusdependent area, the accumulation of bursa-derived lymphoid cells and a certain thymus-dependent factor, was discussed.


Technologies and their applications related to e-commerce have always been the topic of interests to attract researchers and widely discussed. Among them, the use of the mobile agent in e-commerce is a highly potential technology which has accumulated a lot of interests in recent years. Since the mobile agent has high autonomy and mobility, it can move, unbridled, in different execution environments. At the same time, it can automatically detect its current environment and respond accordingly. Finally, it can also carry out work, or tasks assigned to it by its user. The above qualities make the mobile agent very suitable for use in e-commerce. The internet is an open environment. When there is a need to transfer, or exchange confidential information over the internet, the security of the present Internet environment must be improved. Even so, during its execution, a mobile agent needs to roam around the internet between different servers on the internet. At the same time, a mobile agent may also come in contact, or interact with other mobile agents or hosts. Therefore, the users may worry that a mobile agent may not work properly if it meets with a malicious program, or if it is tampered with by a malicious host, or that confidential information carried by the mobile agent may be stolen by other agents. To ensure the safety of mobile agents on the internet, this paper proposes a security scheme suitable for use to mobile agents: The scheme includes access control and key management to ensure the security and confidentiality of information and the system. In view of the access control and key management scheme for mobile agents proposed by Volker and Mehrdad[l], this paper proposes a new scheme that uses the concepts of polynomial interpolation formula[19], the hierarchy structure and the superkey[8] to improve the previous security schemes which need a large amount of space for the mobile agent. According to this paper's security and performance analysis, it is proved that the proposed scheme can efficiently protect the mobile agents.


The application of the influence matrix as method for design planning is often used to guarantee product's quality and reliability in early design phases. Thus, critical elements, which e.g. strongly influence or become influenced by other elements, can be identified by analyzing interdependency networks. Unfortunately, the application of this proceeding in the context of product spectrum analysis is not possible so far. This results from the extensive character of a product spectrum (in contrast to an invariant product), which does not only possess static interdependencies, but general possibilities of element linking. A product spectrum describes a multitude of possible product specifications on an abstract level. In addition, uncertainty must be handled regarding the occurrence of elements and interdependencies. The presented approach introduces the assessment of a new criterion of sensitivity as an extension of criteria, which are commonly used for analyses by static influence matrices. The new sensitivity criterion permits the identification of important elements in a product spectrum and elaborating useful measures for its further development.


Dr. Rodrigues and his team raised awareness of a clinical entity called sudden death in PD (SUDPAR) in their reply to our recently published systematic review about the risk of cardiovascular events in Parkinson's Disease (PD).[1].


Shallow gas in the south of Daqing placanticline is mainly biogas originated from K1n1+2,mixed with a small amount of thermogenic gas of K1qn and inorganic CO2. The main biogas generation and expulsion period of K1n1+2 is the end of K2m sedimentary period,when fault activities caused the formation of anticline and fault trap of Heidimiao oil layer and induced vertical migration of biogas. The composite of the three periods made large amount of biogas migrate into Heidimiao oil layer. Active faults are all boundary faults in fault-condensed belt,along which biogas migrated vertically. The position of biogas accumulation depends on allocation relation between fault and strata of two walls. The wall whose dip is contrary to that of the fault is the main position for biogas accumulation. Generally the southern part of Daqing placanticline is an asymmetric anticline that is gentle in the west and steep in the east. Biogas is mainly accumulated in the traps of the east boundary of fault-condensed belt. There are 5 sets of reservoir-seal assemblages. Cap rock thicknesses of 3 sets of assemblages in the lower part are greater and the probabilities of them to be leaped by faults are relatively small. They are the main target beds. Most of the traps in Heidimiao oil layer are fault traps. The lateral sealing of fault determines trapping potential. The lower limit of SGR required by lateral seal of fault is 0.375. There are 3 kinds of situations when we analyze trapping potential by use of Allen graphic to calibrate lateral sealing of fault or not taking lateral sealing of fault into consideration. The first is that fault is sealing in the lateral and the area and amplitude of trap don't change (type Ⅰ). The second is that the lateral sealing of fault is sectionalized and the area and amplitude of trap become smaller (type Ⅱ). The third is that fault isn't sealing in the lateral and there is no trap (type Ⅲ). Among them,traps of Ⅰand Ⅱare favorable targets for biogas accumulation. The south of Daqing placanticline shows that the key factors of shallow gas accumulation in Songliao basin are integrity of traps controlled by faults that can connect gas source and regional distributed cap rocks.


An analytic investigation into the flow pattern in load-capacity optimized-profile-film thrust bearings is presented. This work shows that recirculatory flow can occur near to the inlet with some film shapes and becomes more extensive as bearing width increases. Of the film profiles investigated, lubricant flow reversal was most, significant in the quadratic type. When compared with linear film, the profile geometries gave enhanced load-carrying ability, but this was accompanied by a decrease in lubricant flowrate and an increase in power consumption. Lubricant inertia effects were most significant for the linear film profile giving increase in load-carying capacity and a decrease in lubricant flow over that where lubricant acceleration was excluded, power losses were affected only marginally.


394 The book, Marking the Mind: A History of Memory , provides a very interesting, readable, and concise account of how our conceptions of memory have developed over the ages. It's author, Kurt Danziger, is a Professor Emeritus at York University in Toronto, who is renowned for his historical writings on the development of psychological categories. In this book, he focuses on the category of memory and its emergence from the writings of the Greeks through more modern-day conceptions. To extrapolate from the leafl et description, the book does an excellent job in confronting neuropsychology's "extremely short present" with its "long past." Most date the emergence of psychology as a formal science back to the mid-19th century with the opening of Wilhelm Wundt's laboratory in Leipzig. While many psychology historians have spent signifi cant time and effort in demonstrating how origins of the fi eld can be linked back to writings of scholars and philosophers from ancient, medieval, and modern times (Watson, 1963 ), this point is likely lost on neuropsychologists, who generally consider their specialty to have developed more recently. What is known is that psychologists began to administer standardized test instruments to patients with brain disorders in Europe and North America prior to the turn of the 20th century (Barr, 2008 ). Halstead's laboratory, established in the 1930s, was the fi rst laboratory established in the United States for the study of brain–behavior relationships. Many consider that Lashley, around the same time, was the fi rst to have used the term "neuropsychology" in his writings. While much experimental (and some clinical) work was proceeding in the 1940s and 1950s, the fi eld of clinical neuropsychology established its roots as a profession in the 1960s and 1970s with the development of professional societies. It has fl ourished in recent decades in light of advances in our knowledge of brain functioning. Within the setting of modern-day neuroscience it is often diffi cult to remember that many of our concepts regarding behavior have origins from long ago. As this volume demonstrates, memory is no exception. In this book, Danziger places memory within a sociohistorical context, demonstrating how the metaphors used to describe this process have, over the ages, paralleled developments in communication technology. In the early chapters, he contrasts the memory demands for ancient storytellers communicating through the oral tradition from those required by medieval monks focusing on the written word. He explains in great detail how the evolution of literacy through the ages has served to remove the source of factual memory from the individual to the external world of recorded facts. He demonstrates that concepts of "episodic" and "semantic" memory existed well in advance of Endel Tulving's seminal contributions on this distinction (Tulving, 1972 ). Similar information can be found regarding most of our knowledge about other distinct forms of memory processing. Other parts of the book focus on philosophical approaches to subjective experience, providing an interesting account of how this type of memory eventually evolved into a biological construct, taking it from its original social context and placing it, literally, within the individual brain. The author discusses how the medical world became interested in diseases of memory in the late 19th century through accounts of amnesia and paramnestic phenomena such as déjà vu. He also specifi es how memory itself became a source of pathology, as viewed within the concept of psychological trauma. He balances his outline of the origin of psychoanalysis and its emphasis on repressed memory by including the possibility that some "susceptible" individuals might undergo life-changing infl uences by memories that are not so traumatic. He does not shy away from exploring the distinction between "historical" and "narrative" truth with their accompanying social and political implications. While reading this book, one readily discovers how the development of psychology as an empirical science has resulted in separating the study of memory from any relationship to context or meaning. This point can be seen most clearly in Ebbinghaus's ( 1913 ) development of the nonsense symbol and extension of this work into experiments performed by learning theorists during the majority of the 20th BOOK REVIEWS


At the beginning of the twenty-first century, alternatives to public education are many and varied. In most Canadian communities, our children can attend neighbourhood public schools, various alternative schools within the public system, independent schools that receive some public funding, independent schools that are entirely outside the public system, or can remain at home to be taught by their parents. This spectrum of alternatives is offered to us in the name of choice and in the service of the principle of diversity. As in other public service sectors, the words diversity and choice have moved to the centre of discussions about system reform. The many educational options that have been created to address diverse needs provide answers for everyone who cares to enter the debate but may prevent us from clearly articulating our expectations of the publicly-funded system or making the more fundamental changes that may be needed. By definition, a publicly-funded system -- such as our education, health, or social service system -- is based on principles of universality and aimed at providing common services at a common level. It is indeed a conundrum to provide this common service to a population that we know to be wildly heterogeneous; but does the answer lie in simply creating a multiplicity of systems until we reach some sort of diversity saturation point where everyone can find his or her individuality served in one or another of its forms? In this paper I will be exploring one alternative to the public education system -- home schooling. While home schooling is at a considerable distance from and runs counter to many of the central principles of the public education system, I believe it has the potential to offer us an important and challenging critique of that system. Rather than dismissing home schooling as a choice that is irrelevant to public school reform, I believe educational reformers, administrators, and teachers have something to learn from parents who choose to teach their children at home. Although home schooling is heavily reported in the news media as a sort of heretical movement, home schooling has received limited research and scholarly attention. Literature on home schooling falls into three categories -- how-to books, first-person testimonials aimed at convincing readers of the merits of home schooling, and a very few research-based studies that aim at scholarly objectivity. This lack of research may, in part, be due to the fact that home schooling represents an overt challenge to the public school system and is thus not apt to be targeted with public or corporate research dollars. In the absence of a consistent and reliable body of research data, this paper focuses on the ideological foundations of home schooling and its place in the menu of choices that currently defines educational policy in Canada.

8528 Background: Improved diagnosis and comprehensive treatment of childhood cancers has increased the overall survival rate. This study assesses physical impairments, functional limitations, health status and behaviors; and vocational and occupational histories of adult survivors of pediatric sarcomas.

METHODS
Physical impairment assessment: Joint range of motion (ROM); manual muscle testing (MMT); hand grip strength (HGS). Functional limitations: Assessment of motor and process skills (AMPS); 6-minute walk (6MWT); and human activity performance (HAP) questionnaire. Health status and behaviors: Leisure satisfaction measure (LSM); SF-36; sickness impact profile (SIP). Vocational and occupational histories: The Goldberg Scale (GS).

STATISTICS
Standardized measures compared patients with norms. The results were evaluated by Wilcoxon signed rank two-sided p-values, unadjusted for multiple comparisons.

RESULTS
32 survivors were diagnosed at median age 15.4 years (male:female=17:15, Ewing's sarcoma in 24/32). ROM of 22 subjects tested was >40% reduced in 12/13 with lower extremity (LE) lesions. HGS equaled matched norms. 28 /32 performed the 6MWT. 3/4 non-ambulatory subjects were LE amputees. Velocity in 9 was <90% predicted. HAP maximum score/maximum adjusted scores were lower than matched norms (p=0.015 and p=0.043 respectively). Motor and process scores for performance of routine daily tasks were lower than normal matched controls (p<0.0001). SF36 physical competency subscale trended lower (p=0.065), mental competency scores trended higher (p=0.058) than normal, respectively. Overall LSM was higher than the control group (p<0.001). Preliminary GS evaluation suggests higher work satisfaction.

CONCLUSION
Survivors of childhood sarcoma have residual impairment of strength and motion, more likely of the lower extremity. Performance(mobility and daily routines), was reduced. Leisure satisfaction and self-reported mental competency higher than matched normal subjects, despite significant physical limitations, may reflect an augmented sense of well-being. Vocational drive and occupational behaviors were above average compared to people with disabilities. No significant financial relationships to disclose.


In order to avoid the disadvantages of adjusting parameter α during the fuzzy controller optimization process,such as non-convenience and difficulties in online realization,design an adjusting function α(t)for a typical controlled object,present a method of realization and optimization of α(t) based on MATLAB,then set up a simulation model of optimal fuzzy control system based on α(t).The simulation results show that the effect of adjusting function α(t)is better than adjusted parameter α,and the parameters of α(t) could be optimized by unconstrained nonlinear minimization with good effects,which make the system meet the target of quick and non-overshoot.


This study aims to investigate the slope protection mechanism of roots. In ecological slope protection, plant roots can fix soil and protect slop through biological and mechanical action. However, previous studies on the slope protection mechanism are still not deep enough and inadequate. By taking four kinds of typical plant roots along Wu-Shen Expressway as the research object, through the indoor tensile test and root morphology observation analysis, the tensile strength and ultimate tension were studied and the influence to the stability of the slope was discussed in this study. The results show that the mean ultimate tension of roots is 7.19~29.96 N. The mean tension of shrub roots is 2~4 times greater than that of herb roots. The ultimate tension of the same plant roots increases with the diameter significantly. To the range of improvement, Shrub roots exceed herb ones. It also indicates that the mean tensile strength of roots are 24.48~74.25 MPa. Compared with the steel HRB235, the tensile strength of herb roots is as great as 1/5~1/3, while Shrub roots is about 1/10~1/5. The slope stability coefficient with plant growing is a positive correlation with roots tension and root number through the sliding surface and is a negative correlation with plants weight. In addition, the slope stability coefficient is related to plant density and root morphology. The test results demonstrate that the roots tension with acute angle or right angle to the landslide surface and the roots shear stiffness with obtuse angle can improve the performance of slope's anti-slide. Four kinds of plants can improve the stability coefficient of shallow soil. As for the slope protection effect, herbage is superior to shrub. In general, grass-shrub mixed community is the ideal system for slope protection.


Microcanonical molecular-dynamics study of spontaneous alloying (SA), which is a manifestation of fast atomic diffusion in a nanosized metal cluster, is done in terms of a simple two-dimensional binary Morse model. Important features observed by Yasuda and Mori are well reproduced in our simulation. The temperature dependence and size dependence of SA phenomena are extensively explored by examining long-time dynamics. The dominant role of negative heat of solution in completing SA is also discussed. We point out that a presence of melting surface induces the diffusion of core atoms even if they are solidlike. In other words, the surface melting at substantially low temperature plays a key role in attaining SA.

At the end of the 19th century, Tolstoy became the spiritual leader of the Russian society. His thoughts embodied the qualities of Russian culture. He held that man could suppress his beastly nature through constant self-examinations and confessions. The restless soul of Russia was eager for its final home instead of material wealth. He detested imposition and suppression and his anarchism ended up being strict self-management and self-suppression. The essence and significance of Tolstoyism was to establish moral order among people and "the pride of man" between the man and the beast at the turn of the century when traditional values broke up.

Abstract This essay explores the relationship between the Critical Legal Studies movement and the Marxist tradition. What role did Marxism play in the formation of CLS's ideological and theoretical horizons? What part was it assigned in the movement's symbolic economy of discursive projects and practices? What kinds of critical challenges did CLS scholars mount against the Marxist legal-theoretic tradition and what sorts of broader lessons can the Marxist tradition extract today from those criticisms? The essay starts by summarising the standard account of the relationship between CLS and Marxism that has historically developed within the CLS's own internal discourse. It problematises a number of basic assumptions underlying this account before turning its attention to the examination of CLS's (potential) contribution to the development of a new wave of the Marxist legal-theoretic enterprise.


Automatic breathing, particularly during sleep, depends on the activity of chemoreceptive neurons that respond to hypoxia, hypercapnia, or both. These neurons provide inputs to a brainstem network that is responsible for generation of the respiratory rhythm and the control of the motor neurons innervating the respiratory muscles.1 Experimental studies indicate that serotonergic and glutamatergic neurons located close to the ventral medullary surface may have a critical role in triggering the ventilatory responses to hypercapnia and hypoxia. There is genetic and neuropathologic evidence that involvement of these chemosensitive neurons may underlie ventilatory failure during sleep in congenital central hypoventilation syndrome (CCHS) and in victims of sudden infant death syndrome (SIDS), and may also contribute to impairment of automatic ventilation in degenerative disorders such as multiple system atrophy (MSA). These new insights into the critical role of neurochemically defined medullary cell groups in control of automatic respiration in humans provide the basis for development of pharmacologic strategies to prevent death due to ventilatory failure during sleep in these and other conditions.

Breathing depends on a central pattern generator that includes neurons located in the dorsolateral pons, nucleus of the solitary tract (NTS), and ventrolateral medulla (ventral respiratory column)1 (figure). The NTS relays inputs from peripheral respiratory chemoreceptors and pulmonary mechanoreceptors to the brainstem respiratory network, and the ventral respiratory column consists of separate populations of neurons that control the activity of inspiratory or expiratory motor neurons. One cell group in the ventral respiratory column, the pre-Botzinger complex, contains neurons that are critical for respiratory rhythmogenesis2 (table).

Summary: This session reviews pertinent information from three clinical cases exploring the experiences of parents seeking healthcare for and alongside their transgender youth at an LGBTQIA+ specialty clinic. Content Outline: 1. Accessing Healthcare is difficult for transgender persons in both adulthood and during formative years. 1. Little, if any, data exists on the experiences of those seeking care for and alongside their transgender youth. 2. Persons identifying as transgender experience many forms of healthcare related discrimination (Kcomt, 2018). 2. Accessible, accountable and comprehensive clinical services are a necessity. 1. Two cases disclosed a willingness to travel between 3-4 hours to the next nearest specialty center. One case disclosed a potential inability for their youth to receive treatment due to an unsurmountable barrier of distance if their current clinic did not exist. 2. Care planning should include telemedicine as evidenced by one case discussing the importance of this modality. 3. All cases discussed managing much of the care as out-of-pocket expenses due to the lack of resources available through health insurance coverage, despite some identified changes in its availability (Plemons, 2018). 4. Baldwin et al. (2018) highlights the importance of leaders and educator's participation in the improvement of care for transgender and non-binary patients, as transphobia in practice exists. Two cases explicitly identified the use of control-seeking power through language and actions of practitioners. 5. In all cases, the youth in question had enormous influence by brining information to both parents and providers. Baldwin et al. identifies this as a barrier to quality care. One case relayed frustration with the burden of independent information gathering required, wanting the providers overseeing their child's care to take more initiative. 6. Lapinski et al. (2018) identify primary care as an area in which competence for working with transgender health issues is paramount, as more patients are seeking care from these types of providers. Shires, Stroumsa, Jaffee and Woodford (2018) assert that primary care centers are willing to care for transgender patients, though reports of negative care interactions exist. 7. One clinical case illustrates the difficulty identified by Newman, Barnhost and Landess (2018) when helping those with intellectual disability diagnoses navigated the many treatment options for transgender patients. 3. Conclusion 1. These clinical cases provide a foundation for research that is informed and relevant as treatment modalities and care planning can look dynamically different from individual to individual. 2. Exploration of the experiences of those who help support transgender youth during their care journey is needed to enhance the individual's holistic environment.

Forty invasive breast ductal carcinoma biopsy specimens were investigated. The techniques of fluorescence and chromogenic in situ hybridization were used to study HER-2/neu gene amplification and the concordance of these techniques was examined. The advantages and disadvantages of both techniques are shown. The optimum ranges of using these techniques in the determination of the herzept status of breast cancer are given.


A resonance $X(3872)$, first observed in the decays $B\ensuremath{\rightarrow}KX$, has been seen to decay to $J/\ensuremath{\psi}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. The ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ mass spectrum peaks near its kinematic upper limit, prompting speculation that the dipion system may be in a ${\ensuremath{\rho}}^{0}$. The decay $X(3872)\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\omega}$ also has been observed. The reaction $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ has been studied. Consequently, angular distributions in decays of $J/\ensuremath{\psi}({\ensuremath{\rho}}^{0},\ensuremath{\omega})$ states near threshold are of interest, and results are presented.


This thesis,based on the analysis of the great changes of fiscal income and economic growth in different areas from 1995 to 2007,has made an empirical study of the relationship between fiscal income and GDP by means of the model of VAR and impulse-response function.The study shows that the response of GDP to the impulsion of one S.D.fiscal income innovation in different areas are positive.But the response are different from the increase of time interval.We can see that the contribution proportion of GDP to the fluctuation of fiscal income in east area is small compared with that in west area,and the maximum amount of contribution exists in middle area clearly.

With the discussion around REACH the interest in ranking of chemicals is increased. In this paper we take a statistical point of view in evaluation and ranking of chemicals. The data matrix with relevant properties of the chemicals plays the central role. Its evaluation is performed by simple concepts of partial order (Hasse diagram technique (HDT)). Several extensions are discussed: First the concept of METEOR (METhod of Evaluation by ORder Theory), then the approach by fuzzy concepts, combined with partial order, and finally the DLPO-concept (Double Layer Partial Orders). DLPO is a novel method where attributes are themselves combined by partial order. The main idea is to avoid the bias due to a functional combination of attributes (for example by weighted sums as in METEOR). Whereas HDT does not need any information beyond the data matrix, all other methods discussed so far, need additional knowledge.


We show that soliton propagation in transmission lines where bandwidth-limited amplification, nonlinear gain or loss, and a strong third-order dispersion are present can be reasonably described in terms of a ''twostage'' perturbation theory. In contrast to the adiabatic soliton perturbation theory which is known to fail beyond a critical strength of third-order dispersion, a modulation of the soliton phase caused by third-order dispersion is taken into account in this approach. @S1063-651X~97!07302-9# PACS number~s!: 42.81.Dp Among others, there are two fundamental problems in using solitons in optical fiber communication lines: to reduce the fiber dispersion ~however, keeping it anomalous! ,i n order to allow the weak Kerr nonlinearity to produce a sufficiently narrow soliton, and to compensate the dissipative losses in long-haul systems @1#, simultaneously suppressing the noise. In order to cope with the former problem, a carrier wavelength near the zero-dispersion point ~ZDP! can be used, which in addition leads to the reduction of the soliton peak power. The latter problem can be resolved by means of bandwidth-limited amplification ~BLA!, i.e., the combined action of optical amplifiers and filters. A complicating factor is that third-order dispersion ~TOD! has usually to be taken into account near the ZDP. Although TOD is a Hamiltonian perturbation it gives rise to the emission of radiation where the so-called resonance radiation separates from the soliton and can entail a complete destruction of the soliton @2‐5#. Moreover, TOD leads to the breakup of the two-soliton bound state @2,6‐8#. But it is also known that other perturbations can be exploited to suppress these detrimental effects of TOD. It was shown in @9# that, e.g., the decay of the two-soliton bound state can be avoided if BLA comes into play. Moreover, it has been predicted @8,10# and experimentally verified lately @11# that BLA may absorb the emitted resonance radiation, thus lending the soliton a much better stability. Thus in view of these observations it is necessary to analyze the dynamical properties of solitons in the presence of several qualitatively different perturbations. The effect of TOD on the dynamical behavior of a single soliton has been intensively studied @12,13,6,14,4,5#. The soliton velocity and frequency shifts which appear due to the presence of TOD can correctly be described by transforming


Despite the convulsive times that we are living as well as the discrepancies and controversies about whether a technique or a drug is better than another is for a specific heart disease, the knowledge of the heart and its mechanical and electrical function is higher every day. For some authors, the electrical cardiac systole only includes the QT interval. That is, the ventricular depolarization and repolarization.


Abstract : This thesis investigated the effects of different scheduling methods on the throughput of Automatic Test Equipment. The types of scheduling considered were first-in-first-out (FIFO), a modified FIFO where all components of the same type were processed in a batch, and a priority scheduling based on determination of the expected time to the next backorder, as predicted by renewal theory, with priority given to the component with the shortest expected time to a backorder. The study was accomplished by constructing a simulation model of the Royal Australian Air Force ATE workshop at 492SQN in South Australia. The repair process was modelled from the time a component became unserviceable to the time it became serviceable again. The arrival process for components was assumed to be Poisson. The ATE testing of components was modelled in detail, but the physical repair and any spares delay were represented by a gamma distribution. The study showed that, for this workshop, the different scheduling methods had little effect because the repair time and spares delay were relatively large, compared to the ATE testing time, and these were the controlling influences in the system. Keywords: Simulation; Automatic test equipment; avionics; maintenance; Job scheduling.

Network embedding models aim to learn low-dimensional representations for nodes and/or edges in graphs. For social networks, learning edge representations is especially beneficial as we need to describe or explain the relationships, activities, and interactions between users. Existing approaches that learn stand-alone node embeddings, and represent edges as pairs of node embeddings, are limited in their applicability because nodes participate in multiple relationships, which should be considered. In addition, social networks often contain multiple types of edges, which yields multi-view contexts that need to be considered in the representation. In this paper, we propose a new methodology, MERL, that (1) captures asymmetry in multiple views by learning well-defined edge representations that are responsive to the difference between the source and destination node roles, and (2) incorporates textual communications to identify multiple source of social signals (e.g. strength and affinity) that moderate the impact of different views between users. Our experiments show that MERL outperforms alternative state-of-the-art embedding models on link prediction and multilabel classification tasks across multiple views in social network datasets. We further analyze the learned embeddings of MERL and demonstrate they are more correlated with the existence of view-based edges compared to previous methods.
