The mineral sector causes socioeconomic and environmental impacts on the surrounding communities. Thus, Social Technologies (STs) developed by universities are an alternative for improving the quality of life of the people affected by mining activities. STs are a Latin American practice comprising solutions for social inclusion and economic development. Thus, this article critically investigates the impacts of mining and STs, reinforcing the potential applications of STs in this field. Additionally, the work discusses the possibilities of technology transfer from the university to society through a comprehensive literature review, and the authors developed guidelines to mitigate the impacts of mining activities using STs implementation with technology transfer as a tool. The literature review showed that, although multiple STs aim at social inclusion, the success of the ST depends on the socio‐technical suitability of each community, an efficient training process, and the capacity for self‐management by the social actors. The guideline created includes aspects of: approach and scenario reconstruction, mapping, identification of vocations, training, and technical support for affected communities. Additionally, the mining sector can use these guidelines as a Corporate Social Responsibility tool.


The structure of copper binding site in bovine serum amine oxidase (BSAO) treated with diethyldithiocarbamate ion(DDC) was discussed by comparing its absorption and electron spin resonance spectra with those of a model copper complex. The structure of the model complex, [Cu(2,2′-bipyridine)(DDC)]+, suggested that at least two nitrogen atoms are coordinated around the copper ion in the native BSAO. Some organic chromophore from which the pink color of BSAO stems was also observed as the difference of the absorption spectra in the region of 450 to 600 nm between BSAO-DDC and the model complex.


Taking the diaphragm wall slurry trench in Ningbo rail transit test section as the study case,the stability of slurry trench with a surcharge using the paracurve cylinder model is analyzed.The influence of model parameters on the sensitivity and the safety factor of slurry trench stability under the protection of slurry wall are discussed.The detection results of plane position,depth and verticality of slurry trench are used to determine the stability of diaphragm wall.Some measures have been successfully applied to the excavation of slurry wall trench,through which the calculation results are validated.It is expected that this research may offer a reliable reference for other similar engineering projects.


We analyze whether changes in external macroeconomic conditions are associated with changes in the dynamics of risk and changes in the degree of informativeness of the price system for the Chilean economy. By focusing our analysis in Chile, we hope to isolate the effect of external macroeconomic volatility from the effects that weak institutions or a poor rule of law might have over domestic markets performance. We find that the dynamics of local financial risks is associated with the evolution of the overall economic conditions of the country, with a strong reduction in idiosyncratic and systematic risks during periods of stable macroeconomic conditions. Since the level and composition of financial risks can affect the net benefits of acquiring and trading on private information, we conjecture that external economic conditions can also affect the informativeness of domestic stock prices. We find that the ability of domestic stock prices to reflect fundamentals information improves during times of stable external conditions. In spite of this, we provide evidence that traditional measures of informationally market efficiency in the R2 literature fail to detect such changes and attempt to explain the reason behind the inability of these measures to properly proxy for stock price informativeness.


Twodifferent states ofhumanimmunodeficiency virus type1areapparent intheasymptomatic andlate stages ofinfection. Important determinants associated withthese twostates havebeenfoundwithin theV3loop oftheviral Envprotein. Inthis study, twolarge datasetsofpublished V3sequenceswere analyzed toidentify patterns ofsequencevariability thatwouldcorrespond tothese twostates ofthevirus. We were especially interested inthepattern ofbasic aminoacidsubstitutions, since thepresenceofbasic aminoacids inV3has beenshowntochange virus tropism incell culture. Fourfeatures ofthesequenceheterogeneity inV3were observed: (i) approximately 70%oofallnonconservative basic substitutions occuratfourpositions inV3,and V3sequenceswitha basic substitution inatleast oneofthese fourpositions contain approximately 95%ofall nonconservative basic substitutions; (ii) substitution patterns within V3 areinfluenced bytheidentity ofthe aminoacidatposition 25;(iii) sequencepolymorphisms account fora significant fraction ofuncharged amino acidsubstitutions atseveral positions inV3,andsequenceheterogeneity other thanthese polymorphisms is mostsignificant attwopositions near thetipofV3;and(iv) sequenceheterogeneity inV3(inaddition tothe basic aminoacidsubstitutions) isapproximately twofold greater inV3sequencesthatcontain basic aminoacid substitutions. Byusing this sequenceanalysis, we were abletoidentify distinct groupsofV3 sequencesin infected patients that appear tocorrespond tothese twovirus states. Theidentification ofthese discrete sequencepatterns invivodemonstrates howtheV3sequencecanbeusedasagenetic markerforstudying the twostates ofhumanimmunodeficiency virus type1.

Aims: The objective of the present study was to evaluate the anti-obesity effects of unripe Rubus coreanus Miquel (uRC) in 3T3-L1 adipocytes and body weight, epididymal fat and perirenal fat weight, and lipid profiles in diet-induced obese (DIO) C57BL/6 mice. Methodology: The lipid accumulation in 3T3-L1 adipocytes was carried out Oil Red O staining. And uRC (50 and 100 mg/kg/day) were orally administered for 90 days from the day of feeding with high fat diet (HFD). The serum total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL)-cholesterol and low density lipoprotein(LDL)-cholesterol and glucose levels were measured using Alere cholesterol LDX system. And the serum glutamic oxaloacetic transaminase (GOT), Short Communication Jung et al; IJBcRR, 5(1): 20-26, 2015; Article no. IJBcRR.2015.003 21 glutamic pyruvic transaminase (GPT), blood urea nitrogen(BUN) and creatinine levels were measured using the respective kits. Results: Our results indicated that treatment with uRC dose-dependently inhibited lipid accumulation in 3T3-L1 adipocytes. Moreover, after oral administration for 12 weeks, uRC (50 and 100mg/kg/day) extract produced a significant decrease in the serum total cholesterol (TC), lowdensity lipoprotein (LDL) cholesterol, glucose and glutamic-oxaloacetic transaminase (GOT) levels of HFD-induced obese mice. Similarly, uRC extract elevated serum high density lipoprotein (HDL) cholesterol. These results suggest that uRC extract may be a useful resource for the management of obesity. Conclusion: These results suggest that uRC extract may be a useful resource for the management of obesity.


This report examines how place-based socially innovative policies and actions can be better integrated into the broader European Union (EU) social agenda. On the basis of previous work and a roundtable taking place in the context of the Improve project, it a) identifies some main challenges for upscaling and consolidating place-based social innovation throughout the European multi-level governance system; b) analyses whether social innovation dovetails with the broader European policy goals of territorial cohesion and public participation, and c) proposes some cautious policy recommendations with regard to how EU resources can be used to better support socially innovative practices. Three main conclusions can be drawn from our analysis. Firstly, the EU supports social innovation both directly (by providing different kinds of resources for local socially innovative projects, not limited to financial resources) and indirectly, by supporting European umbrella organisations operating in the field of poverty and social inclusion. Yet, the degree of innovativeness of EU supported projects differs. Secondly, although EU support for place-based social innovation is significant, it is not consistent throughout the whole life cycle of social innovation. EU support is particularly effective in the early stages of socially innovative projects (conception and start-up). Institutionalisation of those projects depends on domestic circumstances (including welfare regimes' peculiarities) and, what is more surprising given the emphasis at the EU level, EU resources are no used for up-scaling local socially innovative practices. Thirdly, an important challenge is to adapt the increasingly top-down approach in the support of socially innovative projects, with scarce attention being paid to the involvement and empowerment of socially excluded groups.


ABSTRACT The aim of this study was to compare the joint amplitude, spine angulation and displacement of the center of mass during the execution of gafieira samba with and without high heels at different speed. In addition, the reproducibility of the movement was tested. Fifteen experienced dancers performed a sequence of gafieira samba steps under the conditions: high heels (7.5cm) and flats at two speeds according to the beat of music (72 and 96bpm). Kinematic analysis was performed on the Vicon® system with 11 cameras (100 Hz). Twenty-one reflective markers were positioned over the participants' bodies to calculate the center of mass and joint angles of the lower limbs and spine. Reproducibility was determined by the intraclass correlation coefficient and the comparison between conditions was tested by a Two-way Analysis of Variance, with the factors footwear and speed. The results indicated to a moderate to very high reproducibility in all variables analyzed. No differences were found between lumbar curvature, thoracic and displacement of the center of mass. There was no interaction between types of footwear and step execution speed, but analyzing the main factors, there was a decrease in the left ankle plantiflexion angle with increasing speed. The ankle angles showed a significant decrease under the condition flats when compared to high heels. In conclusion, high heels do not alter lumbar curvature, displacement of the center of mass and knee and hip joint amplitude in the execution of gafieira samba.


8548 Background: The percentage of cancer patients ≥ 80 years old is expected to rise in the United States. However data are limited on use of chemotherapy in this group of patients.

METHODS
Retrospective identification of patients who received systemic chemotherapy at our cancer center between 1/1/2000 to 12/31/2004 was performed using the computer generated pharmacy data and medical records. Patients who had diagnosis of cancer and ≥ 80 years were included in the study; patients receiving only supportive care, hormonal therapy, or oral chemotherapy were excluded. The protocol for this study was approved by the Wayne State University IRB.

RESULTS
A total of 133 patients ≥ 80 years who received chemotherapy was analyzed. The median age was 83 and 31% of the patients were ≥ 85 years. There were more females (61%) than males (39%). The gender distribution was more even (47% v. 53%) after excluding gender specific tumors. The racial distribution was diverse- Whites 65 (49%); Blacks 41 (31%); Other 18 (13%); Unknown 9 (7%). 16% of the patients had hematologic malignancy and 84% had solid tumors. Gynecological cancers (32%) followed by aerodigestive cancers (26%) were the most common solid tumors. Solid tumor patients primarily had regional (48%) or distant (45%) disease. During the first regimen, 512 cycles of chemotherapy was delivered with a median of 3 cycles per patient (range 1-24 cycles); 40% of patients received only 2 cycles of chemotherapy. 64% of patients were able to receive chemotherapy without 2nd cycle delay. The distribution of single or multidrug regimens was fairly similar; Solid tumors 52% v. 48%; Hematologic cancers 43% v. 57%. Carboplatin and paclitaxel (22%) was the most common regimen among solid tumor patients. 26% of all patients received a second regimen. The 1 year survival rates among hematologic cancer and solid tumor patients were 65% and 48%, respectively. Stage of disease was the only statistically significant factor predicting survival.

CONCLUSIONS
In this diverse group of cancer patients ≥ 80 years old and selected for chemotherapy, the treatment was feasible. The survival outcomes in this elderly population were comparable to those of a younger patient population suggesting that the treatment is beneficial. No significant financial relationships to disclose.


I recently completed a research project on the religious use of the Semitic root qrb "to come near". The net result was that this root is a thoroughly technical term applied over an extensive field to express a considerable range of inherently related phaenomena. Having covered the Old Testament, the Qumran literature, rabbinic literature, the Qur'an and the Syriac Bible, I established that the religious usage of the root operates mainly (but not exclusively) in three semantic spheres, viz. the cultic, metaphorical and eschatological spheres. We may now discard the latter two as they do not concern us in this paper. As regards the first, a variety of cultic matters is described by the root qrb, their common element being the concept of approaching the holy sphere 1). One nuance in the cultic use of qrb is the subject of our present consideration. I shall endeavour to show that the well-known Greek technical term


Preventing preterm birth is a laudable aim, given its enormous clinical and economic impact to individuals and society. There is a remarkable lack of consensus as to optimal preventative strategies. Prophylactic therapies are increasingly used, but their relative merits remain unclear. Vaginal cerclage has been in common clinical practice since the 1970s, but more recently progesterone has gained popularity. The pessary, which has the advantage of avoiding both surgery and drug administration, is also being more widely investigated. This article is protected by copyright. All rights reserved.


As experimental techniques continue to be developed and improved, they will require more precise contributions from theory. The indirect tests of the Standard Model via high-precision measurements like QWeak and the 11 GeV Møller scattering planned at JLab will demand a complete theoretical evaluation of the next-to-leading order and higher effects in electroweak interactions done with unprecedented precision. We show what kind of theoretical support our group can provide to the above, and other experiments, with the new computational methods we have developed. Some of the key features of our approach, including our method for dealing with many-body effects in e-p scattering and our treatment of Hard Photon Bremsstrahlung, are discussed.

In different parts of the Earth at weather stations accumulated a lot of time series, for example, on various parameters of air in the surface layer. One of the conditions for further development of meteorology is the identification of stable regularities [1-9] on the basis of accumulated statistical data at meteorological stations. And these patterns allow you to better understand the past and predict certain possible behaviors of people making decisions. At the same time, our method of identification of the General wavelet equation (solitary wave) from the measured statistical data will allow to Supplement and clarify the climate mitigation scenarios up to 2100, described in article [1]. Another condition will be the identification of the scenarios of human behavior by their quantitative data of the dynamics of each factor taken into account by their reliability. In this case, only those scenarios for which the wave equations of high adequacy will be obtained will be reliable. The water regime of meadows [3,4] and carbon dynamics in Europe [5] change according to wavelets of universal design [2].


Abstract: Objective: This study aims to determine the trend of seropositivity of anti-SARS-CoV-2 antibodies (total including IgM, Ig G) in patients presenting at a private hospital in Karachi. Materials & Methods: A total of 2500 patients were included in the study. Informed consent was obtained and a questionnaire including patient's age, gender, symptoms, history of traveling, contact with people who had travelled recently, contact with confirmed/suspected COVID-19 patient at home or work was filled. Samples were analyzed for anti-SARS-CoV-2 antibodies on Roche Cobase601. Results: The mean age of the patients was 41.045±20.48 years. 674(26.96%) were reactive, while 1826(73.04%) were non-reactive. Mostly patients were males 1388(55.52%).The seroprevalence was higher in males 29.75% while females showed 23.47% seroprevalence. Commonest symptoms were found to be fever(88.73%) and dry cough(57.20%).The frequency of seropositive patients revealed an increasing trend with 20.5%and 27.8 % in first andlast 15 days of June respectively, 30.7% and 31.4% in first andlast 15 days of July 2020 respectively.Only221(32.79%) reactive patients reported recent symptoms while 453(67.21%)patients were completely asymptomatic.Odds Ratio(OR) for participants with recent history of travelling, contact with people who had travelled recently,exposure with COVID-19 patients at home or work was 11.50, 3.28, 8.45 and 0.72 respectively. Conclusion: The seropositivity has shown a definite gradual upward trend over the study period and approximately two thirds of the patients being completely asymptomatic pointing towards the fact that many people are silently exposed to the disease and develop antibodies through their natural immune mechanism. Keywords: COVID 19, Anti-SARS-CoV-2 antibodies, Trend, Seropositivity, Dry cough, Diarrhea.


We study several procedures for theorem proving based on the resolution principle. We consider (1) Davis Putnam procedure; (2) regular resolution; (3) unrestricted resolution; (4) resolution with extension; and (5) several versions of bounded resolution. The powers of these procedures are compared. Exponential lower bounds are proved for the run-time of some of them.


Synopsis : In this study, the mathematical model for the solid-gas two phase combustion simulation is developed in order to analyze the effect of partial combustion air introduction on coke re-heating behavior in Coke Dry Quencher (CDQ). By introducing combustion air into the pre-chamber of CDQ, the coke quality is expected to be improved. Thus, it is necessary to understand the effect of partial air introduction on transport phenomena in CDQ. The difference of the transport phenomena such as gas flow, gas and coke temperature and concentration of chemical species in CDQ between with and without partial combustion is mainly discussed in this paper. Temperature is about 370K higher in both solid and gas phase with partial air than that without partial combustion around the surface of coke bed due to heat release of volatile matters combustion. In the middle of CDQ, however, the simulation results with partial combustion air introduction show the larger decreasing rate of coke temperature than that without air introduction because not only heat transfer between coke and quenching gas but also endoergic reactions such as C-CO2 and C-H2O are yielded due to higher temperature and more CO2 and H2O. Coke temperature is almost the same, that is 500K, at the bottom of CDQ, coke outlet.

Temperature dependence of I p and I v , with methods used to stabilize these parameters will be discussed.


it is an interesting and informative paper, but I do have some concerns. The main issue with the paper is the lack of a theoretical framework to guide analysis and interpretation. Therefore, the results are presented in a descriptive manner. The aims of the study also need to be strengthened in the light of qualitative research. Methods section need more explanation to improve work: I am not sure about the meaning of secondary interpretive description analysis, what type of study, the number of study participants, consent to participate, interview processes, protecting the confidentiality, data management and so forth. The data presented only show supportive relationships with staff. But how about other data that indicated, for example, negative attitudes of staff? For each quote presented need to introduce it by saying who said it (male/female, age). Perhaps there is a significant difference between these two. Qeios, CC-BY 4.0 · Review, April 26, 2021


There is evidence that accumulation of α‐synuclein (α‐syn) in Parkinson's disease (PD) and dementia with Lewy bodies (DLB) results from impaired removal of α‐syn rather than its overproduction. Kallikrein‐6 (KLK6), calpain‐1 (CAPN1) and cathepsin‐D (CTSD) are among a small number of proteases that cleave α‐syn and are dysregulated in PD and DLB. Our aim in this study was to determine whether protease activity is altered in another α‐synucleinopathy, multiple system atrophy (MSA), and might thereby modulate the regional distribution of α‐syn accumulation.


Various authors (2,28,48) have called our attention to the great disparity existing in the curves of maternal and perinatal mortality. They have pointed out that the latter has decreased relatively little since 1945. Among other reasons, this was due to limited interest in studying the physiology of the human fetus (I) . This has changed within the last ten years however. Because of studies of amniotic fluid, feto-maternal hormones and the application of enzymology, biochemistry, biophysics and electronics to the study of biological phenomena, knowledge about the fetus has been considerably increased. Hypertension is one of the clinical conditions which concerns most obstetricians. It stands out because of its high incidence (8, 1 1 , 18, 25,47) and serious fetal prognosis (2 ,7 ,9 , 12, 15,22,23,25,32, 34, 46). Its manifestation and intensity are particularly important in developing countries, where prenatal assistance and methods for assessing fetal well-being and maturity are limited. Considering these special conditions of developing nations, (within which we are included), we decided to see how far simple tests easily applied and interpreted could reduce fetal loss. These tests could be used to calculate the timing of opportune therapeutic preterm delivery in hypertensive pregnant patients.


We provide an efficient algorithm for computing the smoothing spline score estimator of Cox (1985). The algorithm exploits the banded structure of the linear algebra involved. Calls are made to the LAPACK, Level 1, 2, and 3 BLAS subroutine libraries designed to be efficient on a wide range of modern high-performance computers.


604 liquid capital for the master class. Quite simply, River of Dark Dreams is an incredible tour-de-force that will reshape the way historians think about slavery and capitalism in the antebellum South. There are two criticisms, however. First, the ecological transformations wrought by the rise of the Cotton Kingdom could have been examined in a more systematic way, perhaps dedicating a whole chapter to the subject. Secondly, Johnson did not take the argument far enough in places, especially in regard to the coming of the Civil War. Johnson suggests that nothing short of a unique capitalist system arose concurrently with the free-labor industrial economy of the North. If we take Johnson's argument to its logical conclusion, the Civil War was not between a semifeudal South and a capitalist North and not only about slavery, but it was a struggle between two competing views of economic development and modernity. That said, although it can be a bit dense and abstract in places, this book should be required reading for anyone teaching or studying American history.


The knees are the most easily injured part of the body. The largest and most complicated joint, the knee is used for everything from standing up, sitting, to walking, running, etc. It s a weight-bearing joint that straightens, bends, twists and rotates. All of this motion make you need to keep your knee joint perfectly satisfy. Knee pain is often age-related. In younger people, knee pain is more commonly caused by trauma or overuse, usually related to sports or some physical activity. In age over 40 old, the most likely reason is known as degenerative process. Treatment involves using non-pharmacologic therapeutic modalities include osteopathic manipulative treatment, physical therapy, exercise, use of assistive devices, and weight reduction. Pharmacologic options, categorized as topical, intra-articular, or oral, include acetaminophen, non-steroidal anti-inflammatory agents, and cyclooxygenase type 2 inhibitors. Another way from conventional approaches, patients may consider acupuncture method. Acupuncture involves the insertion of needles the width of a human hair along precise points throughout the body. This process triggers keeps body's energy normal flow through extra anatomy pathway called meridian. Clinical studies are measuring the effectiveness of acupuncture in comparison to more conventional procedures in the treatment of knee pain. In this following case report, it will be shown that there was a man aged 63 years came with complaints left knee pain. Acupuncture technique can help him relieve his knee pain.


This paper shows how I used my research journal mainly as a reflective tool throughout the process of applying for and completing a PhD. Embarking on a PhD can be daunting for anyone and I was challenged by my lack of academic self-efficacy. In the absence of a formal academic mentor my research journal became my confidante, a tool that helped me make progress at times when barriers to research seemed insurmountable. It helped me decrease the cognitive dissonance I was experiencing about issues of subjectivity/objectivity and the positioning of my self in the research. This paper shares research journal entries as I take you on my research journey. The entries make public some of the values I uphold for my research and show how I found ways to embed my own epistemology as an Australian Aboriginal (Koori) researcher into a PhD that also meets a Western academic research paradigm.


29 cases of luteal insufficiency of 634 infertile patients Arzobispo Loayza Hospital corresponding to an incidence of 4.5% were checked. The diagnosis was made by the findings of the endometrial biopsy in 68% of cases found other factors associated with infertility. In the treatment of clomiphene, bromocriptine or 17 hydroxyprogesterone caproate, yielding 9 pregnancies (31%).


IN 1935, R. Foster Moore (i) outlined a new "sharp cut symptom complex" which included the appearance of a special kind of visual hallucination. He reported 26 cases characterized by the simultaneous development of vitreous opacities and so-called "lightning streaks." These appear in the temporal visual field, usually in a vertical direction, and flash periodically on and off for a split second. Although of fairly common occurrence, the syndrome was found only in patients above middle age and more fre-quently in females than in males. The longest duration of the flashes was reported to be approximately three years. Fundi and fields in these patients were normal, and no consequent ocular lesions were found after an adequate period of observation. Moore believed the cause of the lightning streaks to be an increase in the size and final rupture of peripheral retinal cysts. eyes


Nowadays, Scratch, as a widely‐used educational programming platform, has gathered a huge number of programming users all over the world. Facing massive programming resources, how to make satisfactory programming recommendations has attracted increasing attention, especially on explainable recommendations. Existing Scratch recommendation systems overlook to provide why a project is recommended, which prevents users from making better decisions and trusting in the system. To resolve this problem, we design the Scratch‐RL, an explainable reinforcement learning framework over knowledge graphs for Scratch recommendation. First, we devise a preference‐driven Actor‐Critic network to simulate users' local preferences and explore the potential interested projects along the reasoning paths. In the Actor‐Critic network, we elaborate a preference state function, a preference‐based reward function, and a preference‐conditional action pruning strategy for the agent. Then, we leverage a directive discriminator network to help evaluate the correctness of recommendations from the agent and return an extra guidance reward accordingly. A high guidance reward is given when the agent generates correct recommendations, which guarantees that the agent quickly and accurately comprehends the preferences of users. Finally, we jointly train the Actor‐Critic network and the discriminator, when the whole training is done, the reasoning paths are taken as the interpretability of the recommendations. Extensive experiments on both the Scratch data set and public data set show that, Scratch‐RL obtains favorable recommendation results compared with the state‐of‐the‐art models.


This paper will describe an approach by which an English professor and a chemistry professor combined their efforts in a regularly scheduled Instrumental Analysis Laboratory to guide the students' effort in writing better laboratory reports.


An unusual mid-cervical vertebra belonging to a large spinosaurid from the Cenomanian Kem Kem Group of Morocco is described. It is compared to the characteristic morphology of each reconstructed cervical position in Spinosaurus aegyptiacus, based on a recent composite reconstruction that incorporates most previously referred material from this unit. Rather than conforming to any of the previously identified cervical positions in its morphology, the specimen displays a unique combination of mid-cervical characters, with the relatively compact centrum suggesting a position as C4, and the form of the neural arch laminae suggesting a position as C5 or C6. Furthermore, it displays two characters that are previously unknown in spinosaurid mid-cervicals from the Kem Kem Group: a rounded hypapophyseal tuberosity that is not continuous with a ventral keel, and a moderately developed, dorsally oriented epipophysis that does not overhang the postzygapophysis posteriorly. The diagnostic value of positionally variable cervical vertebral characters in spinosaurid systematics is discussed. Although limited, the new data could lend support to the controversial hypothesis that two spinosaurid taxa are represented in the Kem Kem Group.


This article summarises the long-run decline in housing affordability in England and suggests this is substantially attributable to shortfalls in housing supply. Public attitudes to housing have become increasingly pro-development in recent years and the current policy framework – summarised in the article – seeks to provide a comprehensive and rounded response to the challenges facing the housing market.


Strictly Fickian dispersion theory accurately models elution history data in Berea core samples, however, it fails to correctly model the mixing zone growth. A new dispersion model based on the combined effects of spatially varying permeability and Fickian dispersion is presented, which accurately predicts mixing growth zone as well as elution history performance in Berea cores


Dual-Duty Active Site O-linked N-acetylglucosamine transferase (OGT) catalyzes the addition of N-acetylglucosamine (GlcNac) to serine or threonine residues, influencing the localization and function of proteins. Because its activity is sensitive to the nutrient uridine diphosphate (UDP)–GlcNac, OGT has been proposed to regulate cellular responses to nutrient status. Recently, OGT in the presence of UDP-GlcNac was shown to cleave host cell factor–1 (HCF-1), a transcriptional coregulator of human cell-cycle progression. This cleavage is required for HCF-1 maturation. Through a combination of structural, biochemical, and mutagenesis studies, Lazarus et al. (p. 1235) show that both cleavage and glycosylation of HCF-1 occur in the OGT active site. Cleavage occurs between cysteine and glutamine and converts the glutamine into a serine which can then be glycosylated. A protein involved in cell-cycle regulation is proteolytically activated and glycosylated by a nutrient-sensitive enzyme. Host cell factor–1 (HCF-1), a transcriptional co-regulator of human cell-cycle progression, undergoes proteolytic maturation in which any of six repeated sequences is cleaved by the nutrient-responsive glycosyltransferase, O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT). We report that the tetratricopeptide-repeat domain of O-GlcNAc transferase binds the carboxyl-terminal portion of an HCF-1 proteolytic repeat such that the cleavage region lies in the glycosyltransferase active site above uridine diphosphate–GlcNAc. The conformation is similar to that of a glycosylation-competent peptide substrate. Cleavage occurs between cysteine and glutamate residues and results in a pyroglutamate product. Conversion of the cleavage site glutamate into serine converts an HCF-1 proteolytic repeat into a glycosylation substrate. Thus, protein glycosylation and HCF-1 cleavage occur in the same active site.


ObjectiveTo examine the putative protective effect of HIV-2 infection against subsequent HIV-1 infection. DesignRetrospective analysis of data from two cross-sectional surveys in the same community. MethodsTwo surveys between 1989 and 1998 in a rural area in northwestern Guinea-Bissau provided data from residents aged 15–59 years. HIV testing was done in the first survey. In the second survey, tests were made for both HIV and syphilis, and data on sociodemographic factors and sexual behaviour, including commercial sex work, were gathered. Qualitative polymerase chain reaction amplification of HIV-1 and HIV-2 viral DNA was performed on serologically dually reactive samples. ResultsOf the 2276 eligible adult villagers initially tested, 60% (1360) provided a second sample. Of 110 HIV-2-infected subjects, 17 became additionally infected with HIV-1 [incidence rate (IR), 26.3/1000 person-years observation]. Of the 1250 HIV-seronegative subjects, 24 became infected with HIV-1 (IR, 2.8/1000 person-years observation). The incidence rate ratio (IRR), comparing the incidence rate in HIV-2-infected people with the rate in HIV-seronegative subjects, was > 1 in all three 'risk groups': men, female commercial sex workers, and other women. The overall estimate of the IRR, adjusted for age group and risk group, was 3.24 (confidence interval, 1.5–7.1). ConclusionsThere was no protective effect of HIV-2 in this population. HIV-2 cannot be regarded as a vaccine, but, instead, may be a risk factor for HIV-1 infection.

A position-measurement type of laser Doppler velocimeter is proposed. While many conventional LDV systems get information on velocity from the frequency of a Doppler signal, the system proposed in this paper obtains that from the instantaneous phase change. The phase of the Doppler signal is obtained from two signals proportional to sine and cosine of the position of a target, respectively. We get the two signals by using linearly polarized beams. Differential configuration of the measurement system enables us to remove pedestal components of detected signals. This system makes it possible to measure rapidly-changing velocity including direction change and zero velocity without any special devices.


We develop an approach to the dilute-instanton-gas approximation for the Abelian Higgs model when massless fermions are present. We discuss the properties of the resulting partition function and evaluate fermionic correlation functions which become nontrivial when topological sectors are taken into account.


A hybrid resistance exercise technique for strength training of patients with lower-limb paresis was developed. It consists of electrical stimulation-induced contractions (ESIC) superimposed on voluntary contractions to increase recruitment of motor units and the functional load capability of paretic quadriceps and hamstring muscle groups. The feasibility of this hybrid exercise technique was demonstrated in 10 able-bodied subjects during submaximal isometric contractions by eliciting greater forces than the voluntary contractions at given efforts. Mean (/spl plusmn/SE) submaximal voluntary contraction forces (46.4% maximum voluntary contraction forces) for the quadriceps and hamstrings, respectively, were 206.0/spl plusmn/18.0 N and 115.9/spl plusmn/12.7 N, whereas the hybrid forces were 282.7/spl plusmn/30.3 N and 126.1/spl plusmn/12.9 N at ES current levels of 55.6/spl plusmn/7.9 mA and 51.5/spl plusmn/5.7 mA. This represented a 37.2% and an 8.8% increase over the voluntary effort for these muscle groups. Since this hybrid technique recruits additional muscle fibers for stronger contractions, the greater force overload may be more effective for the strength training of patients with lower-limb paresis.


The analytical stance taken by equity researchers in education, the methodologies employed, and the interpretations that are drawn from data all have an enormous impact on the knowledge that is produced about sources of inequality. In the 1970s and 1980s, a great deal of interest was given to the issue of women's and girls' underachievement in mathematics. This prompted numerous different research projects that investigated the extent and nature of the differences between girls' and boys' achievement and offered reasons why such disparities occurred. This work contributed to a discourse on gender and mathematics that flowed through the media channels and into schools, homes, and the workplace. In this article, I consider some of the scholarship on gender and mathematics, critically examining the findings that were produced and the influence they had. In the process, I propose a fundamental tension in research on equity, as scholars walk a fine and precarious line between lack of concern on the one hand and essentialism on the other. I argue in this article that negotiating that tension may be the most critical role for equity researchers as we move into the future.


This article presents a psychological portrayal of a company presented in terms of organizational personality and organizational climate. The assumed psychological research perspective emphasizes factors which significantly influenced the approach to problems concerning a company being part of an international corporation. The important factor in the following case study turned out to be the personality of a general manager in a Polish branch of an international corporation. The article was composed on the basis of empirical research concerning organizational personality.


In this paper, a novel methodology for the design optimization of permanent magnet synchronous machines (PMSM) is presented. It is applied to an outer rotor machine for an unmanned aerial vehicle (UAV). The study shows how, considering all points (up to several thousands) of a working cycle torque/RPM, it is possible to optimize both geometry and control strategy, with the objective of weight and losses minimization while keeping a reduced computational time. With this kind of applications, the working points can have a big variation, which requires a specific method to avoid oversizing and to control multiple constraints in the same time. Hence, the temporal thermal variation is calculated, taking into account the transient. The magnetic saturation, geometrical and electrical constraints are also considered along the working cycle. The electromagnetic model is presented and validated by finite element analysis (FEA).


ABSTRACT We investigate the analytical solution of a two-level system subject to a monochromatical, linearly polarized external field that was first published in 2007. In particular, we derive an explicit expression for the quasienergy. Moreover, we calculate the time evolution of a typical two-level system over a full period by evaluating series solutions of the confluent Heun equation. This is possible without invoking the connection problem of this equation since the complete time evolution of the system under consideration can be reduced to that of the first quarter-period. As a physical application we consider the work performed on a two-level system.


This system takes AT89 series single-chip microcomputer as the core, which constitutes the two ends of the wireless identification device: transponder and reader. The whole system is mainly composed of the smallest single-chip microcomputer system, binary code preset circuit, carrier generation circuit, analog switch control circuit, high-frequency amplifying filter circuit, display circuit and other modules. The transponder part uses the AT89S51 single-chip microcomputer to control the serial output of the preset binary code, uses the active crystal oscillator to generate the carrier wave, and outputs the modulated signal through the analog switch. The reader part amplifies the modulated signal with high frequency, filters the signal, and controls the light-emitting diode to turn on and off to display the identification signal and the four-bit binary code after the acquisition and processing by the single-chip microcomputer. This design realizes the functions of identification, binary code preset and display, single power supply, transmission distance greater than 5cm, time less than 5s, accuracy rate greater than 80%, power less than 2W, transponder storage and other functions.

A FTER World War II there was a wave of self-examination in the field of education from which medical education was not exempt. In 1949 the Survey of Medical Education began, with Dr. John Deitrick as director. Associated with that effort was another study, concerned with the education that students were receiving before going to medical school. This study was supervised by the Subcommittee on Preprofessional Education of the Survey of Medical Education, with Dr. Aura E. Severinghaus as chairman. Dr. Harry J. Carman, who had just retired as dean of Columbia College, was director of this part of the survey, and I took leave from Haverford College to serve as associate director. Dr. Carman or I, or both together, visited IIS colleges and universities in 1950 and 195 i, and from what we learned on those visits, from the proceedings of two national conferences, and from other sources, we gathered the ideas expressed in the report Preparation for Medical Education in the Liberal Arts College, published in 1953. Beginning again in 1958, we revisited most of those same institutions and conducted one more conference. Our second book, published in i96i, described the changes we saw in premedical education, and added a few guarded predictions for the future. We are here to discuss the education of the premedical student. It seems to me that it might be useful to take a look at some of the things


to have a regular pulse with ectopic beats, a fourth sound, and coarse basal crackles. There was a post-herpetic scar extending laterally on the left side of the chest in the T4 dermatome. The ECG showed a typical anterior myocardial infarction, and there were confirmatory enzyme changes. Recovery was uneventful. (3) A bricklayer aged 60 had a head injury in 1960. This was followed by pain in both arms. In 1968 a neurologist found no abnormal physical signs but x-ray examination showed a disc lesion at C4-5. He presented in 1975 with pain radiating to both arms in the distribution of his previous chronic pain but with no chest pain. He was admitted, despite the atypical history, because of ECG changes diagnostic of anteroseptal myocardial infarction. These evolved as usual and were accompanied by enzyme changes. He made an uneventful recovery.


The political culture of the Culture Revolution made it legal for the Culture Revolution form its theory to practice,which strongly sustained and postponed the Culture Revolution.Because the political culture and the Revolution it sustained had an uncompromising inner contradiction,its sustaining and postponing function are limited.


Abstract In 2007 we conducted a contingent valuation survey in Sao Paulo, Brazil, to estimate the population's willingness–to–pay (WTP) to avoid one hospital admission (HA) and one emergency–room visit (ER) due to respiratory diseases in adults and children younger than 5 years old; and cardiovascular diseases in adults only; both associated with atmospheric air pollution. Our annual mean WTP estimates are €81.82 (adult) and €137.92 (child) for HA; €48.40 (adult) and €90.66 (child) for ER due to respiratory diseases; €53.57 (ER) and €90.08 (HA) for cardiovascular diseases. Our results suggest altruism towards children, and a strong income effect on WTP. Results will help analysts evaluating the health benefits of specific policies with potential air pollution impacts in Sao Paulo, Brazil.


The expansion in Information Technology (IT) has inculcated Igbo, one of the three Nigeria major languages in text-based intelligent systems such as text classification, data/information retrieval and natural language processing. The evaluation of an intelligent system and its processes is very important for the progress of the system. This paper presents a performance evaluation of an Igbo text-based intelligent system. A system performance evaluation is the procedure by which a system's resources and results are measured to find out if the system is operating at an optimal level. The performance evaluation of the system was done on classification results of an Igbo text represented with Unigram and Bigram Language Models. Object-Oriented design methodology is used for the work and is implemented with the Python programming language with tools from Natural Language Toolkit (NLTK). The system performance is assessed by calculating the precision, recall and F1-measure of the classification result obtained on Unigram, Bigram and Trigram represented text. Result shows classification on an Igbo Bigram represented text has higher level of precision and accuracy.


In this paper, we propose a novel magnetic field resonance wireless power transfer system using power management by power communication techniques. Power receiving units (PRUs) transmit power control signals to power transmitting units (PTUs) through electromagnetic field resonance controlled by switching devices. The PTU can transfer power only to the authenticated PRU with state transition. In experimental results, the PRU can receive power of more than 500mW and the success rate of power communication is 100% within the transmitting distance of 100mm, which is defined as a Power transmitting distance.


The optimum pH of the DNA-depolymerase produced by Aspergillus quercinus was found to be about 8.5 and maximal formation of the enzyme in the culture medium was observed at the 96th hour. The culture filtrate of Aspergillus quercinus hydrolyzed DNA into 5'-deoxymononucleotides at a pH range higher than 6.0. Each deoxymononucleotide was isolated as crystals in good yield from an enzymatic digest of DNA and characterized spectrophotometrically, enzymatically and by determination of its nitrogen and phosphorus composition. 5'Deoxyinosinic acid was obtained by hydrolysis of DNA with Streptomyces aureus. 5'-Deoxyribotides of hypoxanthine and guanine possessed an attractive taste very similar to that of 5'-inosinic and 5'-guanylic acids.


Downtown Boise, Idaho is a vibrant, safe, and pedestrian friendly city to work, shop, live and play. However, Boise has not always enjoyed its current state of well being. For many years downtown Boise was a desolate wasteland. Very few people frequented downtown, and nearly no one resided downtown. From the late 1960s to the mid 1970s nearly eight city blocks of Boise's Central Business District were demolished with money from Federal Urban Renewal Grants. Thereafter, the redevelopment of downtown Boise was stopped for 15 years due to the supposedly imminent arrival of a downtown, enclosed, retail mall. Thanks to the vision of a few politicians and the actions of a couple of agencies Downtown Boise recovered. This thesis analyzes the mistakes and wisdom of Boise's urban renewal efforts as well as the actions of politicians and agencies in making downtown Boise into a successful mixed-use downtown. In particular, this thesis focuses on what went wrong during Boise's first downtown urban renewal attempt and the actions and practices put into place to ensure the same mistakes did not occur during the second renewal period. I will conclude by highlighting the lessons learned through the process of rejuvenating downtown Boise. This thesis is intended to aid cities that find themselves in the desolate situation Downtown Boise found itself 15 years ago. By understanding both the process by which downtown Boise was changed and the lessons learned throughout the first and second urban renewal endeavors, it is my hope that cities will gain ideas to assist them in the rebuilding and improving of their own downtowns.

This paper describes a pair of patterns that enhance the reuse, extensibility, and portability of object-oriented communication software by permittingnetwork services to evolve independently of the mechanisms used to establish connections used by the services. The Acceptor and Connector patterns decouple the passive and active establishment of a connection, respectively, from the service performed once the connection is established. In addition, the patterns decouple the service creation and concurrency strategies from the services themselves.


Ecological compensation is a mechanism to convert external,non-market values of the environment into real financial incentives for local actors to provide environmental services,which provides a new resolution to protect the environment.From the respects of profile,compensation standards and benefits analysis,this paper describes in detail four typical agro-ecological compensation programs in U.S.A,and summed up the compensation mechanism,characteristics,experience and problems of the agro-ecological compensation.Although the original intention of the U.S.A agro-ecological compensation is to stabilize agricultural market prices,but in the long process of development,it has established a sound legal security system,dynamic management system and differentiated compensation standards.At the same time,it clearly takes the priority compensation measures according to the environmental indicators of specific area,so that the compensation funds can be full used,which are of great importance to the development of ecological compensation in China.


Roll-pitch strap-down seeker has good application prospect. However,the problem of extracting LOS( Line-of-Sight) rate steadily during zenith pass tracking has not been properly solved. We proposed an approach for constructing a virtual "pitch-yaw"seeker by using the seeker's angular position error,gimbal angles and gimbal angle rates. A Kalman filter was also designed whose input is the measurement of the virtual seeker to estimate movement information of the target. And the LOS rate could be extracted indirectly.Simulation results show that the proposed method can restrain the dithering of the LOS rate efficiently during zenith pass tracking and improve the precision of LOS estimation.


N1,N6‐ethenoadenine, ε‐A, nucleos(t)ides have been previously applied as fluorescent probes in numerous biochemical systems. However, these ε‐A analogues lack the H‐bonding capability of adenine. To improve the fluorescence characteristics while preserving the H‐bonding pattern required for molecular recognition, we designed a novel probe: N2,N3‐etheno‐adenosine, (N2,N3‐ε‐A). Here, we describe four novel syntheses of the target ε‐nucleoside and related analogues. These methods are short, facile, and provide the product regiospecifically. In addition, we report the absorption and emission spectra of N2,N3‐ε‐A and the dependence of the spectral features on the pH and polarity of the medium. Specifically, maximum emission of N2,N3‐ε‐A in water is observed at 420 nm (ϕ=0.03, excitation at 290 nm). The biochemical relevance of the new probe was evaluated with respect to the P2Y1 receptor and NTPDases 1 and 2. N2,N3‐ε‐ATP was found to be almost equipotent with ATP at the P2Y1 receptor and was hydrolyzed by NTPDases 1 and 2 at about 80 % of the rate of ATP. Furthermore, protein binding does not seem to shift the fluorescence of N2,N3‐ε‐ATP. Based on the fluorescence and full recognition by ATP‐binding proteins, we propose N2,N3‐ε‐ATP and related nucleo(s)tides as unique probes for the investigation of adenine nucleo(s)tide‐binding proteins as well as for other biochemical applications.

Ecolinguistics or the scientific study of language ecologies and the interaction between language and the environment began as a subdiscipline of applied linguistics in Western universities in the late 1970s. It is primarily concerned with:  How the contours of the natural environment match linguistic contours in respective milieus and vice versa – the ecology of language, and  Environmental discourse analysis – the language of ecology. Despite several seminal works and although much has been written in various volumes covering the theory and epistemology of ecolinguistics, the field still awaits further theoretical expansion and synthesis within itself and together with other fields of enquiry. The multidisciplinary focus of ecolinguistics requires that ecolinguists take a holistic approach embracing a multitude of perspectives both Eastern and Western. It is proposed here that the discipline should strive ahead utilising modern linguistic and environmental theories and technologies while maintaining the validity of ancient basics and practical measures that are the foundation of the area of enquiry. This paper proposes a synthesis of ecolinguistics with: 1) An Indian approach to the treatment of language and environment, i.e. the semantic aspect, and 2) The case study of language evolution and change on Norfolk Island, South Pacific, i.e. an example of communicative adaptation – the pragmatic aspect. It employs two facets for analysis: 1) The Hit Caurasi Pad (Eighty-four Stanzas) of medieval Indian poet Hit Hari Vansh Goswami for its linguistic descriptive power and artistic depiction of humans interacting with Nature in a divine way, and 2) Place names on Norfolk Island in the Norf'k language for their practical, historical and environmental implications and significance. These two case studies aim at finding some suggestions to advancing current thought and theory in ecolinguistics through: 1) Considering the importance of Indian/Eastern aspects of human-environment interaction; and 2) Suggesting the advantage of doing ecolinguistics and placename study on small island environments to hint at various universals and commonalities in linguistic and ecological contact.


Mathematical model has been developed for determination of temperature field in multilayer pavement and subgrade, which considers transfer of heat by conduction and convection, receiving of heat from total solar radiation and atmosphere emission, output of heat due to the emission from the surface of pavement. The developed model has been realized by the finite element method for two dimensional problem using two dimensional second order finite element. Calculations for temperature field have been made with the programme realized on the standard mathematical package MATLAB. Accuracy of the developed model has been evaluated by comparison of temperatures, obtained theoretically and experimentally. The results of comparison showed high accuracy of the model. Long-term calculation (within three months) has been made in pavement points in accordance with the data of meteorological station for air temperature. Some regularities have been determined for variation of temperature field.


The article presents the results of assessing the biological effectiveness of the multicomponent composition of the codling moth sex pheromone under the climateric conditions of RM. In this study, the role of the minor component in the attractiveness of the multicomponent blend of codling moth sex pheromone was determined. In field monitoring trials, various concentrations of the minor component were tested (with decreasing values), the ratio of the components with the highest attractive ability was determined, the decrease of biologic activity of the minor component was directly influenced by the decrease of its concentration in the multicomponent composition of the codling moth sex pheromone.


Aiming at the measurement of roll deformation between two devices, we propose a novel scheme and elaborate the structure design in this paper. The scheme can realize the relative measurement of roll angle even if the system does not provide a reference datum, which effectively solves the problems of limited measurement range of moiré fringes and accuracy guarantee only in an extremely small angle range. First, the principle of measuring the roll angle by moiré fringes is introduced, and the effects of various error sources in the system are comprehensively considered. Then, the combined measurement scheme and the entire system composition structure are analyzed in detail. In addition, an experimental setup is designed to verify the accuracy of roll deformation measurement. The measurement results show that the root mean square (RMS) error can reach <inline-formula> <tex-math notation="LaTeX">$6.9^{\prime \prime }$ </tex-math></inline-formula> within 3°, and is less than <inline-formula> <tex-math notation="LaTeX">$7.8^{\prime \prime }$ </tex-math></inline-formula> in the range of 0°–90°. Hence, our proposed scheme has a good measurement stability in a large roll range.


Extraction of empirical water droplet impingement characteristics from records of wind tunnel dye-tracer experiments has been an extremely time consuming process in the past. Described are a method for extracting impingement data by measuring optical reflectance and a computer controlled laser reflectometer which was designed and built for making these measurements. The instrument increases the efficiency of the data extraction process by at least an order of magnitude. The accuracy of the reflectometer is discussed and some results obtained with the reflectometer are presented. The results are used to verify three-dimensional particle trajectory computer codes, which may then be used for design analysis and certification of aircraft anti-icing/de-icing systems.


Laryngomalacia is the most common cause of stridor in infants. In severe cases, it results in obstructive sleep apnea, cor pulmonale, gastroesophageal reflux, failure to thrive, and pectus excavatum.


The evolution of a superfluorescent pulse is studied in the region of large sample lengths. A solution to the Maxwell–Bloch semiclassical equations is found by using the inverse scattering method. It has the form of a onesoliton solution with varying parameters. Dependence on the pulse width and the retarded time is found without further approximations. These parameters are shown to be independent of the inhomogeneous broadening time. Their values are in good agreement with experiment. Asymmetry of the pulse is also investigated.


LIKE THE MYTHICAL SERPENT who grew two heads for every one he lost, the dividend policy-share price controversy lives on. In a recent issue of the Journal, B. Wallingford [6] derives the optimal dividend policy for a firm whose shareholders are governed by an exponential utility function. The purpose of this comment is to suggest that Wallingford committed an error of omission and that had he considered the problem in its totality, he would have found that share prices are independent of dividend policy regardless of the utility function assumed. In his introductory remarks, Wallingford notes that the dividend debate originally centered on the interrelationship between dividends and investment; with the early proponents assuming (usually implicitly) that dividends and investment expenditures are necessarily inversely related. He then credits Modigliani and Miller [3] with demonstrating that this inverse relationship need not apply when external funds are available and with arguing that, in the absence of such a relationship, dividends are irrelevant for share valuation. But having cut off one head, another immediately appears. For in the next sentence Wallingford states that, "Gordon [1], Lintner [3, 4] and others have pointed out that the Modigliani and Miller argument hinges entirely upon the assumption of the invariance of the discount rate to changes in dividend policy." This observation is the starting point for the author's own work. The basis of Wallingford's model is a valuation equation which represents the current price of the firm's shares as the present value of the certainty equivalent dividend stream discounted at the riskless rate of interest. On the assumption that external equity capital is freely available to the firm, Wallingford uses the familiar sources-equals-uses approach to express the firm's dividends as a function of its earnings, investment and external capital streams. He then calculates the certainty equivalent of this stream assuming that shareholders have a common exponential utility function for dividends. Finally he substitutes this certainty equivalent into the valuation expression and solves for the share price maximizing external capital stream. From there, it is a simple matter to return to the sources-equals-uses equation and to solve for the implied optimal dividend stream. In doing this, Wallingford would seem to have not only demonstrated that dividends are relevant for share valuation, but to have actually solved for the optimal dividend policy in the specific case of an exponential utility function. However, because Wallingford omitted an important element in the problem, his results are not generally valid. To the extent that this is true, the earlier referenced observations of Gordon and Lintner are erroneous as well. The element omitted by Wallingford is the fact that shareholders are not dependent on the firm and its dividend policy for the stream of cash receipts they receive from their shares. If the dividend stream offered by the firm is not the receipt stream they desire, shareholders can alter it by either buying or selling the firm's shares. Thus, when the dividend is too large, the shareholder can reinvest a portion of it in the firm's


A new experimental research method on the electromagnetic susceptibility (EMS) of integrated circuits (ICs) is proposed in this paper. This method is a new research topic based on seeking some basic laws of chip electromagnetic susceptibility, and the purpose is to provide effective reference for chip electromagnetic compatibility (EMC) designers and users. Three different types of interference waveforms are used in the experimental process in which the laws are analyzed and summarized by observing the experimental phenomena and experimental results. The results indicate that the influence of different signal waveforms on the chip EMS presents certain regularity. The results also show that the influence of different chips on the electromagnetic susceptibility presents different characteristics under the same waveform interference. A large number of experiments have been carried out to derive the law of chip electromagnetic susceptibility.


Background and Objectives:Total laryngectomy has become a usual treatment for any advanced carcinoma of the larynx, but most patients who have undergone total laryngectomy have shown permanent disability in voice production. To solve this problem, studies of voice rehabilitation after total laryngectomy have been done. Materials and Methods:We have developed an accurate method to measure the vocal tract shape along its length from magnetic resonance images acquired during the sustained phonation of Korean vowels by T-E shunt patients and normal subject. We estimated the accuracy of MRI and also compared the vocal tract spape of the normal and T-E shunt patients by comparing the first three formant frequencies estimated from MRI to those measured directly from speech data of the T-E patients and the normal subject. Results:The length of T-E shunt patient's vocal tract is 17-18.5 cm. T-E shunt patients phonated strained voice. The length of resonant chamber of T-E shunt patients are shorter than that of the normal subject. The vocal tract is shortened during the phonation by T-E shunt patients. In cases of /e/ and /i/, front cavities are constricted while back cavities are shortened. The pseudoglottis of the T-E shunt patients is located at the region 14-15 cm from lip. Conclusion:Acoustic characteristics and vocal tract shapes of the T-E shunt patients are relatively similar to those of the normal subject. To achieve normal voice, reconstruction of pharyngeal and superior glottal resonant chamber will be desirable. (Korean J Otolaryngol 1998; 41(3 :360-370


evaluated whether low doses of the D1/D2 dopamine receptor agonist apomorphine (0.05 and 0.1 mg/kg, i.p.) was able to counteract the ketamine-induced memory storage impairments in the NORT. We report that ketamine-induced deficit was abolished by apomorphine at both doses. The findings suggest a functional interaction between dopamine and NMDA receptors in the control of memory storage, which may be of relevance to cognitive deficits in schizophrenia.


Abstract The presence of macroscopic fat in an adrenal mass has classically been associated with myelolipoma. Adrenocortical carcinoma is typically an aggressive malignancy with a poor prognosis. The presence of macroscopic fat is not a characteristic finding in adreocortical carcinoma or other adrenal malignancies. We report a case of a newly discovered large adrenal mass containing multiple areas of macroscopic fat, which was pathologically proven to represent an adrenocortical carcinoma.


As the world grapples to combat the spread of COVID-19, our city streets have nearly
emptied. Unprecedented community mitigation interventions have been applied in efforts to
"flatten the curve" and slow the transmission of the virus. Social distancing measures have
dramatically altered our daily behavior; notably, in the ways we do or do not move. This report
seeks to identify emerging trends in urban mobility and road safety in respect to COVID-19.
This is followed by a discussion of how we could shape our mobility future as communities
begin to reopen.


The digital economy is exponentially expanding into every aspect of our lives and industries with sensors, mobile, cloud and big data. This work-in-progress paper will be discussed in 2 parts. Part One will examine the digital firms, fintechs that leverage their capability and large customer base in the digital financial services that include Grab and GoJek and the associated services of digital wallets in Malaysia and neighbouring countries who are "enablers" in the digital economy or "disrupters" in a conventional economy with the growing pool of tech-savvy consumers and rising tide of digital economy and underpinning consumption.
In Part Two, can the digital economy protect the safety, security and privacy of its customers and citizenry? Herein lies the problem – disruptive digital technology, cyberattacks, compromising data breach committed by hackers and fraudsters that could lead to cybercriminals and associated activities of identity theft and so forth. How does the government keep pace with the rapid change and continuing digital disruption in compliance within the legal requirement as innovation is exponentially experienced? This paper will illustrate the security condition of the digital economy risks and the preparedness in facing them as both business and personal risks in Malaysia and global comparison, wherein possible, including existing policies in reinforcing defense in the new norm.


Codon usage bias is a well recognized phenomenon but the relative influence of its major causes: G+C content, mutational biases, and selection, are often difficult to disentangle. This paper presents methods to calculate modified effective codon numbers that allow the investigation of the sources of codon bias and how genes or organisms have their codon biases shaped. In particular, it demonstrates that variation in codon usage bias across organisms is likely driven more by likely mutational forces while the variation in codon usage bias within genomes is likely driven by codon selectional forces. Author summary A new method of disaggregating codon bias influences is described where I show how that different values of the effective codon number, following Wright's Nc, can be used as ratios to demonstrate the similar or different causes of codon biases across genes or organisms. By calculating ratios of the different types of effective codon numbers, one can easily compare organisms or different genes while controlling for gene G+C content or codon nucleotide G+C content. The driving forces determining the variations in codon usage bias across or within organisms thus become much clearer.


Spatio-temporal context (STC) algorithm transforms the tracking process into a series of processes to find the extremum of the confidence map and fully uses the density context information around the target, which makes the algorithm rapidity and robustness. However, STC cannot deal with the situation of scale variation, motion blur and occlusion, which will cause the spatial model update error and result in the failure of the algorithm to accurately extract the target area. To deal with the problem, an improved spatio-temporal context algorithm is proposed in this paper. Firstly, the target sidelobe ratio (PSR) is used to determine the occlusion of the target. The lower the PSR value is, the more serious the target is blocked. PSR can be obtained by analyzing the response map of the target area. Secondly, the scale correlation filter is used to improve the STC algorithm, so that the algorithm can accurately and completely extract the target area. Thirdly, in order to avoid contamination of the target template when the target is occluded, a template update strategy is introduced to adapt to the appearance change of the target. The template update strategy enables our algorithm to locate the target quickly when the occlusion disappearing. Finally, experiment results on public data set are provided to show the effectiveness and robustness of our proposed algorithm.


Achieving a better interface between epoxy and mica particles is the key issue to realize desirable thermal conductivity and low dielectric loss in epoxy-based dielectric materials. In this paper, we report two strategies to improve the interface between synthetic mica and epoxy resin. Polymer coated mica and organically modified mica were prepared by coating polydopamine (PDA) films and grafting a silane coupling agent (KH 560) and fluoro-chemicals via self-polymerization and in situ grafting. The thermal conductivity, dielectric loss and mechanical properties of the epoxy/functionalized mica dielectric materials were markedly improved in comparison with that of the epoxy/mica dielectric materials. The results suggests that the mechanical and dielectric properties of the epoxy/functionalized mica dielectric materials both depended on a good interface and good adhesion between mica and the epoxy matrix. The thermal conductivity of the epoxy/functionalized mica dielectric materials results from a balance of interfacial thermal resistance and quality of the interface. The better overall performance of the epoxy/mica@PDA and mica@PDA@F dielectric materials is attributed to the better interface between mica and epoxy matrix, and provided a new route for preparing epoxy-based dielectric materials with high thermal conductivity and low dielectric loss for use in electronics and the electrical industry.


The authors examined how positive perceptions about partners' attachment security predicted supportive behavior and satisfaction in newlywed marriage. The authors tested a mediation model in which positive perceptions were associated with adaptive support behavior, which in turn predicted increases in marital satisfaction. The self-report measures of attachment security, perceptions of partner's attachment security, and marital satisfaction within 6 months of marriage and again 1 year later were completed by 172 couples. Social support behavior was assessed by videotaped interactions at the initial session. Structural equation models indicated that positive perceptions served a relationship-enhancing function that was enacted, in part, through couples' supportive interactions.


Abstract We studied numerically the frontogenesis of shallow sea fronts such as are observed in the Kii Channel, Japan, during winter, under conditions of sea surface cooling and buoyancy influx from coast and open ocean. Numerical experiments were carried out in a vertically two-dimensional basin with a new model (NH-model), without using the hydrostatic approximation and the convective adjustment. Considering the vertical acceleration term in the momentum equation, intermittent gravitational convections with a large aspect ratio were produced in the frontal region to intensify the horizontal convergence and to strengthen the horizontal density gradient. Consequently, a front in the tracer distribution had a sharpness comparable to the observed front in the Kii Channel and 3.6 times the sharpness in an H-Model, using the hydrostatic approximation and the convective adjustment. In the present model situation, this effect of gravitational convections on sharpening a front in the NH-model is equivalent to t...


TANNAITE rabbis were accustomed to summarize succinctly the 6 n or 613 commandments of the Law in from one to eleven general precepts; * but these summaries were merely private halakoth. Until the second century A.D. there were read in the synagogue service the Ten Words which God himself spoke directly to his people, without the mediation of Moses. A Hebrew papyrus from about 200 B.C. includes the Decalogue with the Shema. And Philo * goes so far as to declare that "the Ten Words are summaries of the special laws which are recorded in the sacred books." In the Hellenistic Judaism represented by Philo the commandments were divided into two sets of five. The first group "begins with God the Father and Maker of all, and ends with parents who copy his nature by begetting particular persons. The other set of five contains all the prohibitions." 8 Some men observe only the first group, others only the second. The latter may be called faXdvdpanroi, the former <j>i\60eoi. Here we find the same kind of summary of the two tables of the Law, possibly interpreting them in the light of the Shema and Leviticus xix. 18, as in the Testaments of the Twelve Patriarchs. And it is interesting to observe the


The B KVV and Cl LVV normal and resonance Auger electron spectra in gaseous BCl3 have been observed with use of tunable photon beam from synchrotron radiation. The spectrum excited by photons with energy above the B K and the Cl L2,3 thresholds shows preferentially Cl LVV normal Auger bands. The pure B KVV normal Auger spectrum is obtained using the photons with energy between the B K threshold and the Cl L pre‐edge excitation threshold. The spectator and participant Auger processes are observed at the B 1s→2a2'(2pπB) and 1s→4e'(σBCl*) resonances. The spectator Auger processes are also observed in the Cl L2,3 excitation region, while the participant Auger processes are not significant in this region. The observed spectra are discussed with the aid of the one‐electron properties of the valence orbitals.


Advances in data bases and distributed processing are resulting in the development of distributed data bases that store data bases at several, distinct computer systems connected by a communication network. Although distributed data bases enable sharing of data resources by users from various nodes of the network, they present many design and control issues. Data must be efficiently stored and accessed by all users from all nodes, and yet be secured against unauthorized use. Considerable research has been devoted to physical data base design and its effects on storage and retrieval, and to security controls in data bases. On the other hand, the mutual relations of physical design and data base security and, in particular, the placement of security controls in a distributed environment has hardly been addressed. This paper fills this gap, in part, by explicitly modeling security control location and cost as part of the physical design of a distributed data base. These considerations result in the introduction of a "restricted access" design methodology, which simplifies the security control. Experimental results reported here concentrate on reducing the data transfer load of the communication network by using the restricted access method compared to more standard schemes. Suggestions are made for development of optimization algorithms for the models presented here.

With the development of remote sensing technique in recent years, high resolution space image shows application potential in many fields, especially in field of city quake calamity evaluation. In this paper, Two IKONOS images of Beijing area are used to classify building types of the city. One is 1m resolution Pan image, the other is 4m resolution and multi spectrum one. After fusion processing, 1m resolution and multi spectrum image is obtained as the basic data for building classification. In order to get best results, some non spectrum information was selected to join the classification process, such as building altitude information which was obtained from the shadow of building and texture. Research shows that different characteristic combination image modes have different classified results. By comparison of four different combination modes, one can see that result, obtained by fusion image, building altitude and texture has best precision, its high building classification precision reaches 80%, and middle and low building classification precisions are all exceed the others results.


Licensed Shared Access (LSA) is a new shared spectrum access model that is gaining traction for unlocking incumbent spectrum to mobile network operators in a form similar to licensed spectrum, thus having the potential to alleviate the spectrum crunch below 6 GHz. Short-term spectrum auctions can pave the way for dynamic LSA in the future and to create incentives for incumbents to voluntarily participate in the LSA model, thereby increase spectrum availability. Different from existing auction schemes that are mostly based on the sealed-bid auction format, we consider an ascending bid format which is theoretically equivalent to a sealed bid format but comes with better behavioral properties. We develop a novel auction mechanism called GAVEL that follows the ascending bid auction format and is well-suited for the dynamic LSA context. GAVEL, besides being strategy-proof, satisfies the three additional desirable properties of supporting heterogeneous spectrum, fine-grained spectrum sharing and bidder privacy protection. In fact, GAVEL is the first mechanism to satisfy all these properties. Through simulation-based evaluations, GAVEL is shown to outperform two recently proposed schemes in terms of revenue, social welfare, number of winners and achieving high spectrum utilization while at the same time performing close to the LP based optimal solution.


Introduction: Optimizing the early diagnosis of childhood hypertrophic cardiomyopathy (HCM) is essential for lowering the risk of HCM-related complications. However, use of standard echocardiography (ECHO) for diagnosis of HCM has been shown to be less sensitive in children than adults, and conventional resting 12-lead ECG is also usually normal in the early stages of HCM. Newer advanced electrocardiograms (A-ECGs) might therefore aid the earlier diagnosis of HCM, especially through their assessment of the spatial QRS-T angle, a parameter that has been suggested to be highly sensitive for HCM in adults and that can be derived from 12to-Frank-lead transformations in software. Recent studies for example have shown that spatial QRS-T angles derived from standard 12-lead ECG recordings by using Kors ́ regression coefficients are statistically equivalent to those derived from simultaneous true Frank XYZ -lead recordings. In this study, we sought to assess whether spatial QRS-T angle and myocardial Tissue Doppler Imaging (TDI) could aid the early diagnosis of HCM in childhood.


A soluble polyimide (SPI) was designed and synthesized,and its solubility and ultraviolet shielding property were studied.After coated with SPI,poly(p-phenylene benzobisoxazole) (PBO) fibers were investigated on their mechanical and anti-ultraviolet aging properties,in which the variations of elongation intensity and the intrinsic viscosity were examined.The research results showed that the PBO fibers coated with SPI possessed better mechanical properties,and the anti-ultraviolet abilities of it was remarkably improved.


Controversial policies in handling the Covid-19 pandemic in Indonesia have become the subject of discussion in online media and social media. The subject of this discussion became a cyberwarfare (war of information), especially in social media which resulted in changes and shifts in public opinion towards the government. Cyberwar that occurs in online media is played by the political buzzer which aims to spread negative propaganda against the government so that it threatens national sovereignty and resilience. The increasingly widespread distribution causes high pressure from the public to immediately take extreme steps to prevent the spread from spreading further. Through social media platforms, there is a cyberwar between netizens to form arguments and discourses that can influence public opinion. Freedom of expression in the use of social media is used as a gap for buzzers to agitate and propaganda to win a cyberwar.

How can processes of innovation towards sustainable intensification, particularly among smallholders, best be supported? Farmer-led experimentation and innovation processes are central to increasing food security among smallholders worldwide, especially in the knowledge-intensive realms of sustainable intensification and agroecological farming. Research and development streams have recognised that successful innovation is a co-evolutionary process, in which technological change occurs with related social and institutional change. Territorial Innovation platforms (IPs), consisting of key actors in a territory (eg. farmers' organisations, cooperatives, government institutions, NGOs) have increasingly focused on brokering interactions among actors in the agricultural innovation system (AIS). The 'mixed crop-livestock-tree' IP in Esteĺı, Nicaragua is an example of such an IP. One goal of the IP is to bring together organisations that work with local smallholders on sustainably intensifying their production systems through agroecological methods. To provide empirical evidence of how such an intervention progresses, this study used quantitative and qualitative methods to explore the composition and activities of the 'mixed crop-livestock-tree' IP, investigating how it performs its functions based on Kilelu et al.'s work on brokering innovation processes. This highlights the importance of brokerage between different AIS actors in co-evolutionary innovation processes, without losing sight of the central importance of smallholders' needs. An analysis of the sub-functions associated with each function demonstrates that the IP has succeeded well in filling the functions network brokerage, innovation process management, and demand articulation. The functions institutional support, capacity building, and knowledge brokering are weakly executed. The scaling up of agroecological practices could be better supported by strengthening the execution of the latter functions, and through a concerted alignment of all functions. Results emphasise that to support the co-evolutionary scaling of innovations, IP functions should be synergistic. This study underscores the importance of functional analyses to highlight obstructions to IPs' satisfying their full potential as brokers in innovation processes.


Electromagnetic welding (EMW) is a specific application of E lectromagnetic Forming (EMF), owing to the fact that the latter very often than not precedes the former, which means that the metallic parts to be welded get deformed before getting welded. This is a new application of electromagnetic field. This being so, there are not much efforts made for the electrical characterization of the equipment to improve it 's performance. The electrical parameter of the system are a nalyzed in detail in this paper for welding of aluminum strips of 1 mm and 2 mm thickness (width = 400 mm and length = 550 mm). The two bodies (to be welded) have necessarily to be separated from each other so that they acquire sufficient velocity bef ore collision. The collision velocity is the important paramet er in this process. The variation in collision velocity is co mputed for a range of separation distances. The optimum separation distance and minimum energy required for welding is computed and experimentally verified. The paper summarizes the analy sis comprising of computational work, substantiated by data for mechanical strength tests and the study of microstructure. The correlation between the quality of weld and collision velocity has been established.


I READwith interest the article by Lenth (2015) and its ensuing discussion about the utility of normal (Daniel) plots of effects. With the exception of the editor himself, all the discussants were from academia so a key voice of those from industry was underrepresented in the discussion. Take it from this practitioner who agrees with Lenth (2015), it is time to retire the Daniel plots from our vocabulary, training and software.

Abstract Lithography provides a high speed method of printing conducting circuit tracks and, potentially, multilayer devices on flexible substrates. The technique relies on the ability to formulate, mix, and print highly filled, powder containing inks. The problem is that the addition of powder at the 40 vol.-% level and above severely embrittles the dried ink film. Furthermore, increasing the build thickness by multiple overprinting increases the stress on bending. Additions to the ink that modify viscosity are known to result in loss of print quality. This paper reports ink formulation and testing that provide flexible ceramic and metal filled inks within these processing constraints.

Rotor asymmetries lead to perturbations of air-gap flux patterns in induction machines. These perturbations in flux components affect a number of components including currents and electromagnetic torque. The supervision of these signals enables early detection of such faults and assists in fault diagnosis. This paper studies the detection of rotor imperfections by spectral analysis of the electromagnetic torque, computed by two stator flux estimators using only noninvasive sensors such as current and voltage sensors. In a first approach, the Extended Luenberger Observer (ELO) is used to estimate stator flux components as well mechanical velocity. A second approach uses a nonlinear High Gain Observer (HGO) for the same purposes. Experimental results and comparison show the significant potential of these methods in detecting these types of faults.
