Session summary High availabihty, sometimes: referred to as fault tolerance, can be considered to be comprised of several classes of activities, e g.: fault detection, fault diagnosis, fault confinement, fault recovery. fault repair, fault reporting, and restart (if necessary). This topic has been the fc~cus of much research m centralized computer systems, and more recently m the context of distributed systems such as networks and distributed computers. The strong interest in high availability and fault tolerance in distributed systems stems not just from their inherently greater fault susceptibility in certain ways (e.g.. data inconsistency) but also from their potential for improved axailabflity over centralized systems (e.g.. physical isolation). However, in general the user of a distributed system takes neither of these perspectives: (s)he has a need which seems best filled by a distributed system, and must overcome availability obstacles and take advantage of availability opportunities. In this session, four invited speakers addressed the topic from different viewpoints. The first two speakers presented projects where the principal mechanism for achieving fault tolerance are atomic transactions supported m the kernel. The third speaker discussed language-based tools for dynamic reconfiguration of d~strtbuted systems. The last speaker presented the fault-tolerance aspects of a network-operating system based on actors messages, and ports. These four presentations are briefly synopsized below. ArchOS E. Douglas Jensen (Carnegie-_Mellon University. USA) outlined a large and long-term project performing research on "decentralized computers", in which a system-wide but physically replicated OS manages all the global resources through teams which negotiate, compromise, and reach a best-effort consensus based on inaccurate and incomplete information. This is supported by a general atomic transaction facility m each instance of the kernel, which provides "compound" nonseriahzable transactions on distributed objects and "failure safety" (both of which are supported by a new formal theory of consistency and correctness), as well as the conventional nested serlahzable transactions and failure atomicity whmh are special cases. Separate prototypes of the transaction kernel and a best-effort resource management kernel (initially confined to time-driven placement and scheduling of real-time processes) are expected to be operational on approximately ten Ethernet'ed Sun F, ticrosystems nodes before the end of the year. Each node is a multiprocessor to avoid OS processing from burdening the application processor; special-purpose OS support hardware is being designed. A complete global decentralized operating system named ArchOS is taking the unusual approach (for a research project) of proceeding through all the …


This research aims to assess the similarities and variances between MDR Pseudomonas aeruginosa clinicalisolates from different infections using MLST molecular typing technique in Baquba city. One hundredeighty clinical samples were collected from urinary tract, wounds and burns infections, included (110)urine, (50) wounds and (20) burns. Twenty isolates (11.11%) of Pseudomonas aeruginosa were diagnosedbased on microscopic, morphological, biochemical tests and confirmed by VITEK-2 system. Antibioticsusceptibility test for the twenty isolates was performed against six antibiotics using disk diffusion method,the results showed (100%) resistance for Cephalothin, Ceftazdim (60%), Colistin (35%), Amikacin (25%),Ciprofloxacin (20%), while (0%) resistance for Imipenem. The results also showed that 16 (80%) of isolateswere produced extended spectrum beta-lactamase (ES?L) and did not show their production for Metallobeta-lactamase (M?Ls). Biofilm was detected by Micro-Titer Plate method and the result showed that all theisolates (100%) were biofilm producers. Multi-locus sequence typing (MLST) was used because broadnessand ease of access of MLST database. Seven housekeeping genes (acsA, aroE, guaA, mutL, nuoD, ppsA,andtrpE) were sequenced and the results were compared with MLST database and allele profile for eachisolate was used to determine sequence types (STs).New Iraqi bacterial strain has been identified andrecorded in database of MLST (PubMLST) under the name (AS-85U).


Pseudomonas, a common bacterium is found in soil, water, skin flora and in most of the man made environments such as Hospital, Industry, Effluent treatment plant. Pseudomonas aeruginosa one of the most important opportunistic pathogen which causes nosocomial infections to the patient in Intensive care unit has become a major threat in the medical care. It also exhibits multidrug resistance which has drawn the attention of the microbiologist. The characteristic feature of Pseudomonas aeruginosa is the production of soluble green pigment pyocyanin, which act as a bio-indicator for the identification of a contaminant in hospital environment. Pyocyanin produced as a secondary metabolite exhibits antifungal activity by both disc diffusion and liquid culture methods. The present study was undertaken to determine the frequency of occurrence of Pseudomonas aeruginosa in patient population attending an outpatient department. The study also includes to demonstrate the pigment production on various solid and liquid media. Further, the pigment pyocyanin was extracted and confirmed by using the solvent chloroform. The pigment was separated by thin layer chromatography and purified by column chromatography. Fraction which was obtained from TLC was used to determine the MIC and the antifungal activity against Candida albicans, Candida tropicalis, Candida glabarata Cryptococcus neoformans and Aspergillus fumigatus which concluded that pyocyanin pigment has the ability to inhibit the growth of various fungi by arresting the electron transport in both in vitro and in vivo conditions.


As noted in the preface, this piece constitutes the first half of a chapter as written by the late Edward H. Spicer. The second half, though further developing his ideas, is not specific to the American Indian and so is not included here. The final section printed here, which offers a pungent statement, is Spicer's conclusion to that chapter. The book was never completed because of his untimely death. 1. Edward H.

The discrepancies are revealed between the retrieved ozone profiles.


The Auntie Dialogues is a special journal issue of "The Auntie Is In" podcast scripts. This decolonial approach to research dissemination is aimed at layering Indigenous storytelling alongside written literature. In the sixteen episodes presented in Season One, Dr. Paulina Johnson, or the Auntie, bridges her approach with an "Auntie" mentality to address misconceptions and stereotypes about Indigenous peoples and cultures and better inform listeners of Indigenous realities. The podcast does not solely look at damage or deficit but also the vibrancy of Nehiyawak culture including knowledge relating to creation stories, traditions, ceremonies, and much more. Dr. Johnson is Nêhiyaw or Paskwâw-iyiniw, four-spirit or a prairie person, from Nipisihkopahk, Samson Cree Nation in Maskwacis, Alberta. The Nehiyawak are an oral culture, meaning they share information, through stories, songs, and everyday conversations, and the podcast allows Dr. Johnson to maintain that connection to her people and how knowledge can be shared and importantly to be as straightforward as needed as your own auntie would be to you. By grounding each podcast episode in ceremony and sharing the oral narratives and her own stories and experiences Dr. Johnson is able to facilitate the learning and unlearning needed for decolonization and importantly, reconciliation. These articles are the dialogues of the Auntie is in.


This paper presents a SiC JFET-based, 200 °C, 50 kW three-phase inverter module and evaluates its electrical performance. With 1200 V, 100 A rating of the module, each switching element is composed of four paralleled SiC JFETs with two anti-parallel SiC Shottky Barrier Diodes (SBDs). The substrate layout inside the module is designed to reduce package parasitics. Then, experimental static characteristics of the module are obtained over a wide range of temperature, and low on-state resistance is shown up to 200 °C. The dynamic performance of this module is evaluated by double pulse test up to 150 °C, under 650 V dc bus voltage and 60 A drain current, with different turn-on and turn-off gate resistances. The current unbalance phenomenon and phase-leg shoot-through problem are analyzed too. The results by simulation and experiments show that the causes of shoot-through are JFET inside parameters, package parasitics, and high temperature. The switching losses of this module at different temperatures are shown at the end.


The instances are notorious, and they are representative. The more recent cases are in entire agreement.

In this paper we present the alpha-prototype of the WAKE-up, a wearable robotic device for the rehabilitation of locomotion of pediatric subjects with neurological diseases such as Cerebral Palsy. The WAKE-up is an active knee-ankle orthosis. It is composed of two robotic modules for the rehabilitation of knee and ankle, respectively. Each module can be utilized either alone or together with the other one. The working principle is based on series elastic actuators (SEA), i.e., dc motors equipped with a torsional spring mounted in series to avoid the direct connection of the actuator with the patient's limb. A SEA permits the control of the force and the emulation of different orthoses with given value of stiffness. The torque transmission is achieved by a timing belt and it is mediated by a torsional spring. The experimental tests conducted on each modules confirmed a good precision of the spring deflection control (position error <; 2°) and good overall performances of the force control obtained with the spring stiffness chosen at the design phase.


Summary It was hypothesized that S s working in the presence of an observer (n = 25) would set higher goals than would S s working alone (n = 32) and that there would be a significant goal-performance relationship for S s working alone but not for S s observed. The results of a task-performance exercise supported both hypotheses. Average performance did not differ across conditions.

Objective Our objective was to compare the clinical and radio graphic results of unilateral pedicle screw fixation (UPSF) and bilateral pedicle screw fixation (BPSF) after unilateral transforaminal lumbar interbody fusion ( TLIF) for the treatment of lumbar degenerative disc diseases (DDD). Materials and methods 63 patients who underwent UPSF or BPSF combined wit h unilateral TLIF at L4-L5 or L5-S1 were included in our hospital from 2014-2016. The perioperative outcomes and radiographic results were recorded at preoperative and postoperative follow-up. Fusion rates were determined according to the Bridw ell-Lenke grading system. Clinical outcomes were evaluated by the VAS, the OD I and the lumbar JOA. Results According to the perioperative assessments, the ope ration duration, intraand postoperative blood loss, painkiller used time, and hospital costs of UPSF group were significantly (p<0.0001) less than the BPSF group. After mean 24 months follow-up, both UPSF and BPSF significantly (p<0.05) maintaine d the disk height and segmental lordosis of surgical segment and achieve similar cl inical outcomes at final follow-up postoperative. The impacts of UPSF on the cranial a djacent vertebra level were significantly (p<0.05) smaller than the BPSF group in the short-term. Conclusion UPSF techniques with TLIF can attain similar clinic al efficiency in treating of low lumbar DDD with single level, compared with BPSF te chniques, but UPSF techniques with less surgical injuries and cost. BP SF with TLIF probably cause more degeneration at the cranial adjacent segment, when compared with UPSF techniques.

Plant origin drugs have played a fundamental role in prevention and treatment of diseases since ancient time. WHO estimates that about 80% of the world's population use traditional medicine for most of the diseases by administration of plant or plant products. Sandroos (Trachylobium hornnemannianum) is an important resin which is obtained from Sal tree, botanically known as 'Shorea robusta', belongs to the family Leguminosae. It is abundantly found in forests of Africa, Australia, Spain and India. Sandroos has been used since millennia in Unani system of medicine in various ailments like obesity, haemoptysis, ulcers and lipid metabolic disorders. This review discusses about the thorough description of Sandroos in both Unani as well as modern literature, its source, medicinal properties and phytochemical constituents.

This study was carried out to investigate damp injury caused by tomato coir bag culture and prevent that. The tomato variety was used 'Minichal', and tomatoes were grown in greenhouse. The nutrient solution based on Yamazaki Tomato Standard Solution was irrigated from one hour after sunrise to two hour before sunset. The slits for darainage were made in three types; I, L, and bottom slit type. The coir bag of I and L type had six slits of 15cm length, that of bottom slit type had three slits of 15 cm length. The weight of coir bag in 24 hours after saturation was 14.2 kg in I type, 13.8 kg in L type, and 12.8 kg in bottom slit type, but there was not significant difference. The weight of coir bag after one day irrigation was 14.5 kg, 14.2 kg, and 13.3 kg at L, I, and bottm slit type, respectively. This means that the moisture content of coir bag during cultivation was lowest in bottom slit type. The number of adventitious root on stem was 160, 170, and 53 at I, L, and bottom slit type, respectively. The dry weight of root and root length were highest at bottom slit type, compared to other treatment. The marketable yield was highest 26.5 kg/20 plant in bottom slit type. For increasing yield and preventing damp injury, bottom slit type was most effective at U type bed coir bag culture.

The ability of brucella to localize and remain viable within the cells of an infected host must be considered an important factor in explaining the relapses following therapy and the tendency toward chronicity of this disease. Experimental evidence supporting this concept has been provided by the observation of Magoffin and Spink (1) that intracellular brucella are protected in vitro against the lethal effect of therapeutic agents. In order to extend these observations a method has been developed which permits a quantitative in tritro study of the basic unit involved in brucellosis. This basic unit is a viable host cell containing viable intracellular bruceUa. Exudative leukocytes containing large numbers of intracellular brucella have been maintained in ~itro in a synthetic tissue culture medium, or in human or animal serum. The methods used in these studies have permitted an evaluation of the effect of therapeutic agents and the bactericidal action of animal or human serum on intra-cellular brucella. In addition the metabolic status of the host cell has been correlated with its ability to protect the intracellular organisms. The metabolic activity of both host cells and intracellular organisms has been investigated by direct microscopic observation of the reduction of tetrazolium salts to pig-mented formazans. Methods Adult, male white rats were injected intraperitoneally with 8 ml. of sterile sodium caseinate to produce a peritoneal exudate. The sodium caseinate was prepared from pure casein by the method of Martin eta/. (2). 8 hours later 5 billion brucella organisms in 5 ml. of physiological saline solution were injected into the peritoneal cavity containing the exudate and in v/vo phagocytosis allowed to proceed for 16 hours. Preliminary studies indicated that at the end of this time practically all the leukocytes in the exudate contained brucella and very few organisms remained in an extracellular position. The animal was then anesthetized and exsanguin-ated by cutting the large neck vessels. The skin of the abdomen was prepared with tincture of zephiran 1:1000 and the peritoneal cavity opened aseptically. 20 or 30 ml. of sterile he-parinized (1:5000) Simms-X7 solution t was introduced into the peritoneal cavity through a All tissue culture media used in these studies were obtained from Microbiological Associ


The impact of diffusion profile shaping through the use of tensilely and compressively strained diffusion masks on the modulation response of single-mode vertical-cavity surface-emitting lasers (VCSELs) using disorder-defined apertures is investigated. VCSELs designed for high-power single-fundamental-mode emission through the use apertures defined via impurity-induced disordering (IID) in conjunction with a standard oxide-confinement process are characterized to extract high-frequency optical cavity parameters across oxide aperture and diffusion mask strain variations. The 3-dB small-signal bandwidth is maintained for a 7.68 mW single-mode 850 nm VCSEL with an oxide aperture of 13 $\mu \text{m}$ using a tensilely strained diffusion mask relative to a non-disordered multimode device of the same oxide aperture. A large K-factor reduction is also observed, from 0.248 ns to 0.045 ns, indicating that damping and photon lifetimes within the cavity of VCSELs employing disorder-defined apertures are substantially reduced. Performance implications to data communication applications are discussed.


characterizing mentioned above electrical conductivity parameters of Ukrainian soils is considered. The basis for similar researches is Taren's theorem. The randomness of the studied dynamical system given by time realizations is established by means of Lyapunov's indicator. The state stability is estimated by Hausdorf 's fractal dimension and the fractality index. Visual evaluation of the time series was carried out by means of the phase trajectory restoration procedure. As a result of the analysis of phase points in the phase space the split attractor is indicated, which gives the chaise to speak about its bifurcation.


Abstract : This study identified rates of diagnosis-specific musculoskeletal injuries in United States Marine Corps (USMC) recruits, and examined the association between patterns of physical training and these injuries. Subjects were 1,296 randomly selected USMC male recruits, ages 17 to 28 years, who reported to Marine Corps Recruit Depot (MCRD) San Diego for boot camp training between January 12 and September 14, 1993. Recruits were followed prospectively through 12 weeks of training for injury outcomes. Weekly volumes and types of vigorous physical training were correlated with injury patterns. The overall injury rate was 39.6%, with 82% of injuries occurring in the lower extremities. Overuse injuries accounted for 78% of the diagnoses. The most frequent site of injury was the ankle/foot region (34.3% injuries), followed by the knee (28.1%). Ankle sprains (6.2%, n = 1,143), iliotibial band syndrome (5.3%, n = 1,143), and stress fractures (4.0%, n= 1,296) were the most common diagnoses. The highest rates of injury were reported during the first 3 weeks of training and during weeks 8,10, and 11. These weeks included high total volumes of vigorous physical training and the greatest number of hours of running and military marching.


by Dr. Ewart in the Lancet of 29th August, 1891, form a new feature. Stress is also laid upon the existence of a normal dulness over the great vessels. A simple but complete code of symbols is suggested for the registration of cardiac murmurs, and of variations in the normal sounds. The figures, with which the book is amply illustrated, are correct and clear, and accurately represent the relations of parts within the chest. The appended clinical outlines, however, though excellent for recording murmurs, show too small a portion of the chest wall,


This study takes a close look at one teacher's interpretation of Quebec's new science curriculum in a grade six classroom where the student population is culturally diverse. Over a period of two months, I conducted classroom observations on a twice-weekly basis. Data were also collected from two interviews and several informal discussions with the teacher. The data depicted several of the teaching methods and strategies that seem effective for multicultural classrooms and portrayed a positive interaction between the students and the teacher. These were coupled with the teacher's personal style that was appropriate for a culturally diverse classroom. These results are discussed in the light of Quebec's new curriculum reform and the existing literature on multiculturalism and are used to portray a picture of multicultural science education.


The variable camber continuous trailing edge flap (VCCTEF) concept offers potential improvements in the aerodynamic efficiency of aircraft through real time wing shaping. NASA and Boeing have been studying the suitability of this concept to address the drag reduction problem in aircraft with reduced-stiffness wings. However, reduced stiffness may lead to wing flutter. In addition, displacements of VCCTEF control surfaces are limited and subject to highly nonlinear and time-varying constraints. Hence control design needs to solve a constrained multiobjective optimization problem. To address these challenges, under a recent SBIR project SSCI carried out initial development and testing of the Drag Identification and Reduction Technology (DIRECT). The DIRECT estimates aeroservoelastic states on-line and uses that information in a robust predictive controller to suppress flutter. DIRECT also estimates wind disturbances and selects optimal controller parameters form a table lookup to achieve on-line drag minimization. In the paper we describe our initial development of the DIRECT technology along with plans for wind tunnel testing under the current Phase II SBIR project.


ABSTRACT Soil phosphorous (P) can limit plant growth due to its fixation which stipulates the changes occuring due to imbalanced fertilization in pearl millet-wheat system. The study was aimed to identify the long-term effect of fertilizers and manures on availability of P due to changes in soil inorganic (Pi) and organic P (Po) pools at 0–15, 15–30, 30–60, and 60–90 cm. A sequential methodology was used to determine the effect of fertilizers and manures w.r.t. control (CK) on pools of P and their distribution in soil profile. Fertilizers and manures significantly increased the total and available P concentration. Labile (LOP) and moderately labile (MLOP) organic phosphorous concentrations significantly (P < .05) impacted throughout the soil profile. However, moderately and highly stable organic P pools (MSOP & HSOP) were significantly higher at surface soils. Integrating manures with fertilizers (NPKM) for 10 years increased the LOP and MLOP by 121.5 and 50.0%, while the concentration of MSOP and HSOP was higher under fertilizer treatments (NPK and BFSTCR) at surface soils. The Pi associated with Saloid-P, Aluminium-P, and Iron-P showed decreasing concentration, while calcium-phosphorous concentration increased at all soil depths. The increase in residual-P was more pronounced at lower depths. The proportion of Pi to the total P increased to 16.8% in fertilizer treatments at 30–60 and 60–90 cm soil, while Po proportions increased to 21.0% at 0–15 cm soil. Integrating manures with fertilizers could be a viable nutrient management practice of enhancing the Po and Pi and their availability to plants in sandy soils of Inceptisols.


In the presence of KI, iodine crystals dissolve rapidly in an aqueous solution forming triiodide ions (I3-) and other neutral species. The experimental evidence does not support the formation of polyiodide ions such as I5-, I7-, etc. in the solution. However, there is a strong evidence suggesting the formation of polyiodine species, I2x, where x = 2, 3, etc., stabilized by H+ ions in the solution. Ab initio results are presented for structures and energies of some of these species with an x value of up to 4. Each geometry optimization was done at the HF/LANL2DZ level followed by a single-point energy calculation at the MP2/LANL2DZ level. These calculations suggest that the isolated polyiodine species are not stable and, among the complexed species, the protonated clusters are most stable.


A rapid population growth in Greylag geese (Anser anser) has led to a conflict between geese and farmers due to the foraging geese in agricultural fields which causes damage to crops by trampling and grazing. Culling cannot always be used as a management tool due to protection of the species and temporal restrictions of hunting seasons. Therefore, non-lethal methods such as different scaring techniques and alternative reserved feeding areas, i.e. accommodation fields, have been developed to try to push them away from agricultural fields and pull them to these reserved feeding areas. To enhance the non-lethal management, more knowledge was needed about the geese such as crop selection and distribution patterns e.g. the selection of fields in relation to distance to roost sites. In this study the geese crop selection was estimated by compositional analyses over a three year period (March-October in 2010-2012) around Sorfjarden, Sweden. Moreover, the distribution of geese in relation to distance to roost sites was studied. The compositional analysis showed that the geese selected the acommodation field and grassland more than expected for 2010 and 2011, but that wheat was the top ranked crop in 2012. However, the selection of the accomodation field and grassland was more pronounced during early summer and the selection of grass fields´ declined during late summer. The geese shifted to cereals such as wheat (Triticum spp.), barley (Hordeum vulgare) and pea (Pisum spp.) in late summer, probably because of higher availability due to the harvest and waist grains on the stubble fields. No significant results were found on geese distribution of distance to roost site, due to clumped distances to roost sites in the study area. In conclusion, accommodation fields are a good non-lethal method to ease the grazing pressure on agriculture fields especially during early summer in Sorfjarden.

Liver proteins from mice injected subcutaneously with cadmium chloride (3 mg Cd/kg body weight) were separated on G-75 Sephadex at intervals 20 min.-21 days after injection. Fairly soon after the injection, cadmium was found bound to proteins of high molecular weight whereas at survival times exceeding 24 hours the cadmium was associated with a low molecular weight protein. In mice repeatedly exposed to cadmium (0.25 mg/kg, daily, 5 days/week) for periods up to 5 months, cadmium was principally bound to the low molecular weight protein, which has characteristics in common with the earlier described protein, metallothionein. The importance of "mouse metallothionein" in the toxicity of cadmium is discussed.


A dose of 500 or 1000 ml respectively was infused at hourly intervals over 12 or 24 hours respectively, using a standardised infusion schedule. It was found that this enormous increase in renal function did not cause any changes in the behaviour of the serum levels of oxytetracycline and doxycycline as compared to normal renal excretion. This result comes hardly as a surprise in the case of doxycycline due to its high degree of protein binding, it is, however, unexpected for oxytetracycline.


Against the backdrop of globalisation and the European integration process, identity con-cepts of young Europeans are becoming more diverse and complex. It is commonly assumed that lan-guage and identity are closely connected and that identities are shaped to a large extent through discur-sive practices. These interactions no longer take place in the mother tongue alone; in many instances, they are increasingly affected by the wide use of English as a lingua franca (ELF) in Europe. This raises the question whether a European identity should be built upon linguistic diversity, as officially promoted by the European Union, or whether the use of ELF could help to fulfil this unifying function. Drawing on a questionnaire survey conducted at the University of Braunschweig with 1061 students, the article investigates the potential role of ELF in the formation of a common European identity.

The level of use of the internet and digital platforms in Indonesia is quite even, making it easy to find various content on the internet. YouTube is a digital platform that is commonly used by the public to upload their creativity. These uploads can have a positive or negative impact in the form of violations. This study uses normative juridical research methods with descriptive research specifications. Based on the results of this study, it was found that music covers can be categorized as violations of moral rights within certain limits, such as changing lyrics without permission. The responsibility of digital platforms is also limited through the Safe Harbor Doctrine, namely as long as electronic system operators have carried out their obligations in providing a system that is safe, reliable and in accordance with laws and regulations, the digital platform can be free from responsibility for violations that occur on its platform.


Pregnancy-associated cervicocephalic arterial dissection is rare, and its pathophysiology remains poorly understood. Despite the hypothesized contribution to pathogenesis, connective tissue diseases and genetic factors are rarely identified in clinical cases. We describe a case of postpartum arterial dissection involving all four cervicocephalic arteries resulting in acute cerebral infarction. The patient underwent successful endovascular thrombectomy and angioplasty and recovered fully without sequelae. Genetic screening for connective tissue diseases identified a heterozygous missense COL5A1 variant with unknown clinical significance. Two genetically related family members later developed arterial abnormalities, and one of them tested positive for the same COL5A1 gene variant as our patient, while the other was scheduled for genetic testing. The extensive clinical presentation of our patient and the prevalence of arterial abnormalities in her family warrant further assessment of the association between the identified COL5A1 gene variant and the pathogenesis of arterial dissections.

We present three examples of topological semantics for intuitionistic modal logic with one modal operator □. We show that it is possible to treat neighborhood models, introduced earlier, as topological or multi-topological. From the neighborhood point of view, our method is based on differences between properties of minimal and maximal neighborhoods. Also we propose transformation of multitopological spaces into the neighborhood structures.


The millenium's newest computer-based busi-ness game will be presented by its author. The presentation will cover the rationales for the various design decisions that were made, the wide array of talents assembled by its publisher, South-Western College Publishing, and a "walking tour" of the simulation's Player and Game Administrator Windowsi›™-based applications.


Non-specific low back pain (LBP) is one of the commonest conditions afflicting adults of working age. It represents a leading cause of disability and a major cause of sickness absence. Neck pain and its associated disability are scarcely less common. Collectively, back and neck pain pose a major challenge to employers. Occupational health professionals should be competent when assessing workers with these conditions and be aware of evidence-based advances in the management and rehabilitation of mechanical LBP. Adoption of consensus guidelines has led to better coping and faster recovery. This chapter reviews these initiatives and the problem of assessing fitness for work in those with spinal pain. Emphasis is given to simple, non-specific spinal pain as this is the commonest presentation. Only rarely does the clinician make a more specific diagnosis, but occasionally serious pathology underlies symptoms and different responses are needed. Therefore, this chapter also considers more specific spinal problems and interventions.

Gross Domestic Product is one aspect of the critical success of a country's economy. Gross Domestic Product consists of several factors that consist of Cost, Investation, Government, Export, Import. The value on one of these factors can aect the value of Gross Domestic Product is going to happen. Exports and investment have an increasing trend from year to year a considerable impetus to the movement of gross domestic product. From the results of the study authors using data exports, investment and Gross Domestic Product from 1995 to 2009, shows the in uence and the relationship between exports and investment to Gross Domestic Product. The results using multiple correlation analysis, multiple determination, and test f, shows that there is a correlation Exports and Investment to Gross Domestic Product amounting to 0.852. Calculation of multiple determination value of 0.727,which means that the in uence of Exports and Investment to Gross Domestic Product by 72.7


Web analytics, which reference the collection and analysis of information via internet sites, are being increasingly adopted by media organizations in carrying out research on audiences. It is unclear if this same trend is visible in academia despite the adoption of online tools to carry out research. Web analytics provide a view of audience behavior online and may prove relevant in excavating data about audiences and their preferences in media and communication research. It is, however, important to understand the perception of media and communication researchers to this audience research method. The study utilized the survey method to investigate four research hypotheses on the adoption of web analytics, perceptions on the relevance of data derived from web analytics and perception of reliability and trustworthiness of web analytics as an audience research method. The results indicate that media and communication researchers in UNILAG were significantly familiar with web analytics, and perceived it as a trustworthy source for data gathering.


This article provides an overview of what appears to be a major change in national transportation policy of the United States. It focuses on the legislative efforts to integrate high speed ground transportation (HSGT) systems into the intermodal mix of methods of moving people throughout the country. In order to put this developing policy within its proper perspective, the status of HSGT in the United States is compared to developments in Europe and Japan. This is followed by a discussion of the policy objectives of the Intermodal Surface Transportation Efficiency Act pf 1991 (ISTEA), legislation which was designed to promote efficiency, cost effectiveness and environmental sensitivity in our nation's transportation planning process. The article then analyzes the Clinton Administration's High Speed Rail Development Act of 1993 in an effort to identify the obstacles that HSGT must overcome to be implemented effectively into the nation's intermodal transportation network.


Health insurance decisions are a challenge for many consumers and influence welfare, health outcomes, and longevity. Two choice architecture tools are examined that can improve these decisions: informed ordering of options (from best to worst) and choice set partitioning. It is hypothesized that these tools can improve choices by changing: (1) decision focus: the options in a set on which consumers focus their attention, and (2) decision strategy: how consumers integrate the different attributes that make up the options. The first experiment focuses on the mediating role of the hypothesized decision processes on consumer decision outcomes. The outcome results are validated further in a field study of over 40,000 consumers making actual health insurance choices and in two additional experiments. The results show that informed ordering and partitioning can reduce consumers' mistakes by hundreds of dollars per year. They suggest that wise choice architecture interventions depend upon two factors: The quality of the user model possessed by the firm to predict consumers' best choice and possible interactions among the ensemble of choice architecture tools.


Doctor and patients perceive the importance of lupus medications differently. In this article, we feature a UAB-derived decision aid that highlights key considerations.


Few herbicide options are available for controlling post-emergence weeds in the chickpea. The aim of this work therefore, was to study the selectivity of herbicides applied post-emergence for the chickpea 'BRS Aleppo'. Two experiments were carried out, one in the greenhouse and the other in the field (winter-spring crop). A completely randomised experimental design was used for the screening experiment (greenhouse), with 15 treatments and four replications. Fourteen treatments with herbicides (g a.i. ha-1) were evaluated: bentazon (360 and 720), chlorimuron (10 and 20), clethodim (54 and 108), fluazifop (94 and 188), fomesafen (125 and 250), haloxyfop (30 and 60) and lactofen (90 and 180), in addition to the control with no application. From this experiment, herbicides that did not impair growth in the chickpea were selected for the field experiment based on plant height and shoot dry matter. During the field stage, a randomised block design was used, with 11 treatments and three replications. Ten treatments including the herbicides clethodim, fluazifop, fomesafen, haloxyfop and lactofen were evaluated in two rates, in addition to the control with no application. Based on the results of the two experiments, it was concluded that the ACCase inhibitors (clethodim, fluazifop and haloxyfop) caused no lesions or damage to the chickpea, while the latifolicides (fomesafen and lactofen) caused visual lesions which did not result in significant loss in yield. Bentazon (360 and 720 g a.i. ha-1) and chlorimuron-ethyl (10 and 20 a.i. g ha-1) were not selective, causing severe damage to the chickpea plants.


The analysis of ocular fundus images is important for the detection of disease, tracking changes in the retina over time, and 3D retinal reconstruction. Blood vessel analysis plays a major role in such processing. We propose to use a shortest path analysis to identify blood vessels in retinal images. Ideally, the shortest path between every pair of pixels (where speed through a pixel is proportional to the gray level) would be found, and then a counter incremented for every pixel on the path. Once all pixel paths through a pixel have been counted, the highest counts should correspond to vessel pixels. However, this has exponential complexity in the number of pixels. Thus, not all pixel pairs can be analyzed. We investigate here the selection of a small subset of pixels to seed the process, and propose two methods: (1) the curl method, and (2) the ID degree 2 polynomial method.


This paper presents a novel recurrent time continuous neural network model which performs nonlinear fractional optimization subject to interval constraints on each of the optimization variables. The network is proved to be complete in the sense that the set of optima of the objective function to be minimized with interval constraints coincides with the set of equilibria of the neural network. It is also shown that the network is primal and globally convergent in the sense that its trajectory cannot escape from the feasible region and will converge to an exact optimal solution for any initial point being chosen in the feasible interval region. Simulation results are given to demonstrate further the global convergence and good performance of the proposing neural network for nonlinear fractional programming problems with interval constraints.


A serious scientific journal seems to be the wrong place for a paper on alchemy. However, we believe that the history of science includes knowledge of the complex relations between specific scientific disciplines and what is called the "world-view" (Weltanschauung): the image of the world corresponding to a given stage of cultural development. The world-view, born of the "marriage" of Aristotle's philosophy with Christian theology, was for many centuries largely predominant in Europe of the Middle Ages and of the Renaissance. The "scientific revolution" [1] of the 16–17th centuries: the birth of the "new cosmology" of Copernicus, Galileo, and Kepler and of the "new mechanics" of Galileo and Newton was limited to the physical science, but its direct consequence was the appearance of the "new philosophy". The mechanistic, rationalist and empirical philosophy of the enlightenment rejected the magic elements of the medieval world-view. Without actually being directly concerned by new theories or denied by newly discovered facts, a number of disciplines did not survive such changes in the intellectual climate. We will try to show how alchemy, an integral part of the medieval world-view, was doomed to death by the spirit of enlightenment well before its official death which coincided with the appearance of the modern chemistry of Lavoisier and Dalton. Only its phantom is still alive.


This essay is to explore the musical tropes underlying Fray Luis's mystical homage to his friend Salinas, with the aim of bringing the relationship between music and mysticism in the 16th century into sharper focus. His citation of Pythagoras and Augustine is crucial to an understanding of Fray Luis's poem, with its evocation of the harmony of the spheres and its tacit assumption of the ability of music to awaken the soul to contemplation of the divine. The historiographical tradition of seeing Spanish sacred music of the 16th century tthrough a glass darklyt has tended to muddy the waters as regards the relationship between music and mysticism. Trend's attempt to divorce musical development from its broader cultural context by suggesting that Victoria's style could be explained purely by the influence of the Italian madrigalists is perhaps an understandable reaction to the nationalistically inspired notion of Victoria as mystic. Keywords: Augustine; glass darkly; Italian madrigalists; mysticism; Pythagoras; Spanish; Victoria


Reading and literature are struggling for relevance an environment where attention and the data they provide are seen as key motivators for commercial actors, and there is great pressure for those actors to provide engaging media to secure a meaningful market share. Thus, this media has to attract and keep user attention as quickly and as continuously as possible. The only limiting factors being those of time and energy of the user. Leisure hours that allowed periods for unbroken concentration and perusal of written texts are now devoted to online activities. What is not debated is that the effort and focus required to engage with the writer of fiction or other longer texts cannot be as automatically assumed now as it was before the digital age. Therefore, how can or should reading and literature and our notion of them and their purposes change?

Human liver blood flow has been measured by the colloid disappear ance rate method in one pathological and in two experimental conditions. The eating of a light meal always produced an increase in blood flow, while the administration of epinephrine produced quite variable results. The degree b.ut not the direction of this variability was proportional to the dose of epinephrine. Increased splanchnic blood flow was obse.rved in chronic lymph atic leukemia, and was correlated with spleen size.


We explore transient grating formation in CS2 with femtosecond pulses. The spatially periodic excitation changes the nonlinear refractive index of the medium periodically, resulting in diffraction of the probe beam. The pump power dependence of the self-diffraction efficiency shows a second order power-law indicating the process involving a third-order nonlinearity. Time-resolved diffraction of the probe beam measured with a photodiode gives the third-order autocorrelated signal. CS2 having large third order nonlinearity in a broad range of wavelengths in the visible and near-infrared, is proposed to be a promising candidate for measuring the pulse-widths for pulses generated from optical parametric amplifiers (OPA) using this technique.


The forms of organization within a great lord's household were of profound significance in the late Middle Ages. The resident working household of family and servants, cooks, clerks, minstrels, chaplains and others were often supplemented by the itinerant or occasional household, the lord's affinity, including feed retainers. This friendly cast was the vessel which carried the flow of lordship and patronage, in grants and fees, wages and influence, and provided the services on which the actions of lordship rested. Amongst them was that group distinctively treated by virtue of having been retained by indenture for life. Some 156 examples from the period 1278 to 1476 have recently been published. 1 A second example from the archives of the Mainwaring family of Over Peover (in Cheshire), sadly came to light too late for the full text to be included.2 There seems to have been no unique occasion for such grants. The genuine expectation of long future service could jostle with the offer of a life grant only in the hope of loyalty in a present crisis. And there seems to have been no service, whether menial or not, which was excluded from such written agreements. 3 Whether such service was performed at a distance, in war, in the law courts or by mere friendship in the region, the focus remained the household, often literally the house.4 Lords wore their buildings, investing their architectural patronage with the symbols of family and household, colonizing and exploiting the physical dominance of hall and chapel in the landscape. Forms of organization within the households of great lords also extended in more modest character to those of the


Cowpea, mung bean, Kidney bean and red bean are simular properties. In order to elucidate the similarity among these four starches, some physicochemical properties of starches were compared. Water binding capacity of kidney bean and red bean (199%) starches are higher than mung bean and cowpea. The solubility, swlling power and optical transmittance of the four starches showed a similar pattern, but kidney bean and red bean starches had a lower swelling power than cowpea starches. Cowpea, mung bean, kidney bean and red bean starches had the blue value of 0.41, 0.47, 0.42 and 0.50, the alkali content of 8.4, 8.0, 4.13, 4.13, the amylose content of amylose of 30,000, 29,268, 52, 173 and 33, 611 and glucose unit per segment of amylopectin of 27.6, 26.8, 18.35 and 12.9 respectively. The results of X-ray diffraction studies showed A pattern for four starches.


Tomato seedlings were subjected to light and nutrient stress to determine the effects of each of these stress factors as well as their combined effects on some morphological parameters of the plant. A two-way  Analysis of Variance (ANOVA) carried out on the data obtained showed that light produced significant effect on all the parameters measured except on the shoot height. Nutrient however did not produce any significant effect on any of the morphological parameters measured. There was also no significant interactive effect of light and nutrient on the morphological parameters measured. Keywords : Stress, Light, Nutrient, Morphology, Lycopersicum.


This paper mainly takes the difference between Chinese and English speech signals in linguistics as a guide. Then, it processes and analyzes these speech signals. Finally, it compares the characteristics of these two kinds of speech signals. This thesis adopts short-time energy based scheme to detect voice activity adaptively and then calculate the short-time zero crossing rate, along with using the method of average magnitude difference function of nonlinear center clipping to estimate speech pitch. This paper carries out experiments on voice data from a large number of broadcast programs. Moreover, it uses statistical analysis to verify the difference between the characteristics of the two types of speech signals.


In this paper, the current knowledge of the cratering record of Jupiter's largest icy satellites Ganymede and Callisto are reviewed and strategies for further investigations using images from the JANUS camera aboard ESA's future JUICE mission are discussed.


GRP-type composites (Glass-fibre Reinforced Plastics) have been continuously employed in the oil industry in recent years, often on platforms, especially in pipes for water or oil under moderate temperatures. In this case, the pipes are usually connected through adhesive joints and, consequently, the detection of defects in these joints, as areas without adhesive or adhesive failure (disbonding), gains great importance. One-sided inspection on the joint surface (front side) is a challenging task because the material thickness easily exceeds 10 mm that is far beyond the limits of the capacity of thermography applied to GRP inspection, as confirmed by the experience. Detection limits have been evaluated both theoretically and experimentally as a function of outer wall thickness and defect lateral size. The 3D modeling was accomplished by using the ThermoCalc-6L software. The experimental unit consisted of a FLIR SC640 and NEC TH- 9100 IR imagers and some home-made heaters with the power from 1,5 to 30 kW. The results obtained by applying pulsed heating have demonstrated that the inspection efficiency is strongly dependent on the outer wall thickness with a value of about 8 mm being a detection limit.


Because of its popularity and rapid growth, Facebook has become a viable advertising medium for corporations to communicate with their consumers. The experiences of Facebook users are important to ensure the success of any Facebook advertising campaign. This chapter reports the findings from a qualitative study using the Experience Sampling Method (ESM) after recruiting Facebook college participants in a large university in the Southwest U.S. The ESM technique is a powerful tool to collect data to demonstrate participants' actual experiences and reflections when using Facebook and Facebook advertising. The authors use a signal contingent protocol to record participants' experiences in using Facebook and Facebook advertising after prompting participants to record their using experiences randomly. The findings will help online advertising researchers to better understand the feasibility of using Facebook as a potential advertising medium through a non-survey-based method to better assess potential impacts on businesses.


In this paper, equations are established to solve problems of Rhumb Line Sailing (RLS) on an oblate spheroid. Solutions are provided for both the inverse problem and the direct problem, thereby providing a complete solution to RLS. Development of these solutions was achieved in part by means of computer based symbolic algebra. The inverse solution described attains a high degree of accuracy for distance and azimuth. The direct solution has been obtained from a solution for latitude in terms of distance derived with the introduction of an inverse series expansion of meridian arc-length via the rectifying latitude. Also, a series to determine latitude at any longitude has been derived via the conformal latitude. This was achieved through application of Hermite's Interpolation Scheme or the Lagrange Inversion Theorem. Numerical examples show that the algorithms are very accurate and that the differences between original data and recovered data after applying the inverse or direct solution of RLS to recover the data calculated by the direct or inverse solution are very small. It reveals that the algorithms provided here are suitable for programming implementation and can be applied in the areas of maritime routing and cartographical computation in Graphical Information System (GIS) and Electronic Chart Display and Information System (ECDIS) environments.


This paper reports the results of a web-based study of the perceptions of accounting journals in Australasia. Journal ranking studies have generally adopted citation techniques or used academics' perceptions as the basis for assessing journal quality. Our research contributes to the existing literature by conducting a survey of academics in Australasia using a web-based instrument. The analysis indicates that the perceptions of the so-called "elite" accounting journals have become unsettled. The research highlights the emergence of more recent, alternative paradigm journals (CPA and AAAJ) as both highly ranking.


The asymptotic behavior (such as houndness,tending to zero)of the solution to the equation L_nX(t)+ sum from (j=0) to m b_j(t)f_j(X(t-τ_j(t)))=P(t) is presented(here L_n*=1/(P_n(t))d/(dt)1/(P_(n-1)(t))…d/(dt)1/(P_1(t))d/(dt)*/(P_0(t)),0τ_j(t)≤τ, j=0,…,m).


In this work, we present a novel approach that allows a robot to improve its own navigation performance through introspection and then targeted data retrieval. It is a step in the direction of life-long learning and adaptation and is motivated by the desire to build robots that have plastic competencies which are not baked in. They should react to and benefit from use. We consider a particular instantiation of this problem in the context of place recognition. Based on a topic-based probabilistic representation for images, we use a measure of perplexity to evaluate how well a working set of background images explain the robot's online view of the world. Offline, the robot then searches an external resource to seek out additional background images that bolster its ability to localize in its environment when used next. In this way the robot adapts and improves performance through use. We demonstrate this approach using data collected from a mobile robot operating in outdoor workspaces.


DURING the last two and a half years we have been developing techniques to investigate peripheral glucose metabolism and we have already reported some of our findings elsewhere (Butterfield et al., 1958; Butterfield and Holling,1959). When we realized that small doses of insulin injected into the brachial artery were fixed in the forearm tissues, we thought it would be of interest to measure the direct effect of insulin on the local tissue glucose uptake. In this paper we present


Nigeria was declared the poverty headquarters of the world in June 2018, having overtaken India, with an estimated 86.9 million (44.2%) of her population living in extreme poverty. Exactly a year after, precisely June 2019, the figure has risen to around 93.7 million (47.7%), an increase of 6.8 million (3.5%) people living on less than US$1.90 per day. This is not surprising as poverty trend over the years has maintained an increasing pattern, defiling every policy initiative put in place to combat it.


In this study the relationship between perceived organizational support, affective commitment and job satisfaction are investigated using data obtained from 219 full-time employees of three hospital on healt sector. The data, collected from 219 health care workers in various hospitals of Sakarya province, were used to analyze the relations between the variables. After the verificative factor analysis, the data were analyzed by correlation analysis and regression models. The correlation analysis showed that perceived organizational support, affective commitment and job satisfaction were related. The regression analysis also showed that perceived organizational support has meaningful effects on affetive commitment andjob satisfaction. Job satisfaction has meaningful effect on affective commitment. This study serves as an important guide for those who aim to increase employees' job satisfaction resulting in lower turnover rates in a rapidly changing environment.


1606 Background: While the COVID pandemic elevated the usage of telehealth to unprecedented levels, it remains unclear whether telehealth use is sustained after the initial pandemic era, and whether there remain demographic differences in telehealth utilization. In this study, we compared telehealth trends amongst different demographic populations in a large integrated healthcare system. Methods: Utilization of various visit types (office, video, telephone) was investigated in this population-based retrospective cohort study at 22 Kaiser Permanente Northern California Hematology and Oncology clinics from 10/1/2020 to 6/1/2022. We explored trends associated with the COVID 19 pandemic and after the initial pandemic era as well as demographic differences, using Chi-square for categorical and the Mann-Whitney U Test for non-parametric comparisons. Results: During the study period, there were 341,089 hematology/oncology visits with MD/DO providers, including 83,756 (24.5%) office, 125,162 (36.7%) video, and 132,171 (38.7%) telephone. Total monthly visits remained stable, with a monthly average of 1,765 (10.9%) for new visits and 14,476 (89.1%) for return visits. Monthly telehealth visits (telephone + video) peaked in January, 2021 (85.6% of total visits) and subsequently declined by June, 2022 (68.7% of total visits). Telephone visits increased from 46.1% of telehealth visits to 58.9% over the study period. Amongst telehealth visits, video visits remained popular for new appointments (56.9%) while telephone visits were more common for return appointments (60.7%). After the initial pandemic era, telehealth utilization continued to differ amongst different demographic populations. Video visits remained a significantly higher fraction of all visits (p<0.01) in: (1) less than 45 year-old (60.0%) compared to older than 80 year-old (33.2%); (2) primary English speakers (50.7%) compared to those who require an interpreter (41.5%); (3) patients with commercial insurance (58.2%) compared to those with Medicaid (47.0%) or Medicare (45.2%); (4) non-Hispanic Whites (51.4%) and Asians (52.2%) compared to Hispanic Whites (45.0%) and Blacks (43.6%); (5) patients with the lowest neighborhood deprivation index (NDI) quartile (living in the least deprived neighborhood) (54.0%) vs the highest quartile (46.1%). Conclusions: After the initial pandemic era, telehealth utilization declined slightly over time but remained a common method of providing oncology care. Video visits continued to be widely utilized for initial visits whereas there was a shift to telephone visits for follow up appointments over time. Disparities in telehealth, especially in video visits, continued to be seen in various demographic populations by age, English proficiency, insurance plan, race/ethnicity and neighborhood deprivation index. Continued high utilization of telehealth should inform policy and practices in the post-pandemic era.

Glacial phenomena of the islands. Eeminiscences of the " Great Ice Age" were met with on every island visited. Sometimes the stria? were finely preserved, at other times they were faint, and only the deeper ruts were conspicuous upon the smoothed faces ; while in very many cases all the more delicate ice-markings had disappeared, and only the characteristic rounded and dome-shaped outlines remained. The Till or Boulder-clay, not often so much as 15 feet in thickness, closely resembled the similar deposit which occurs in the hilly and mountainous districts of Scotland. It lay either upon low undulating grounds, or was closely packed together behind rocks, whose abraded and ice-worn faces were quite destitute of any such covering. All the stones and boulders in the Till were of local origin, and in the many exposures which were examined, no fragment which might not have been derived from the islands themselves was found. All consisted of basalt rocks and tuff, and chiefly of the former. This Till, in the author's opinion, represents the groundmoraine of the old ice-sheet that covered the islands. All the little lakes, with one or two exceptions, were found to occupy true rock-basins, excavated by ice-action under varyrng conditions. To many interesting matters we must but briefly allude under the headings of the " Origin of the Valleys and Fiords," " Atmospheric Erosion," " Former Greater Eainfall," " Marine Erosion," and lastly "Peat and Buried Trees"—all of which, besides other subjects, are treated more or less fully, according to the information he could gather, and always in the lucid and graphic style so characteristic of the author. The memoir is illustrated by a map and three plates of sections.


Particle system is one of the way for the modeling of fuzzy object.In battlefield envivronment simulation,particle system model is used to simulate nature phenomena(rain,snow and cloud) and artificial phenomena(waterfall,trail,fire and smoke).In this paper we described the theory of particle system,and achieved some classic particle system.


This work studies the quantitative stability of the quadratic optimal transport map between a fixed probability density $\rho$ and a probability measure $\mu$ on R^d , which we denote T$\mu$. Assuming that the source density $\rho$ is bounded from above and below on a compact convex set, we prove that the map $\mu$ $\rightarrow$ T$\mu$ is bi-H{\"o}lder continuous on large families of probability measures, such as the set of probability measures whose moment of order p>d is bounded by some constant. These stability estimates show that the linearized optimal transport metric W2,$\rho$($\mu$, $\nu$) = T$\mu$ -- T$\nu$ L 2 ($\rho$,R d) is bi-H{\"o}lder equivalent to the 2-Wasserstein distance on such sets, justifiying its use in applications.


This review introduces the synthesis of some newly 1-phenyl (3-chloro-4-methoxy, 2-methoxy5-methyl)- 4(substituted) phenyl benzeneazo acetyl acetone-3,5-dimethyl pyrazoles (4a-4l, 5a-5l) containing different selected functional groups have been synthesized by condensing (3-chloro-4methoxy, 2-methoxy-5-methyl) phenyl benzeneazo acetyl acetone hydrazone (1a,2a) with (R I ) -malon phenyl anilic acid hydrazide (3a-3i,3j,3j 1 ,3k,3k 1 -3l) in alcoholic medium, presence of glacial acetic acid as a catalyst. The identity of newly synthesized compounds were confirmed on the basis of their spectral studies viz- IR, physical properties, elemental analysis.


Feng Qi's enrichment and development for Marxism Epistemology mainly embodies the following three aspects: to consider special epistemology as general epistemology, and regard wisdom as an important goal of epistemology; to summarize the new category of Marxist Epistemology; to plead properly for some views on Marxist Epistemology.


Research has shown that attending a preschool program produces academic, cognitive and behavioral benefits, but that these benefits weaken over time and vary by socioeconomic status and race. Controlling for a wide range of observable child, family, home and school characteristics, this study uses the ECLS-K dataset to evaluate the relationship between Head Start or Center-based pre-K program attendance and math test scores among lower socioeconomic status children by race. I find that while there are short-term gains in math achievement for Black children who attend center based preschool, all benefits that may be associated with pre-K fade by the Spring of 3 rd grade across all races. However, other factors related to the child's home and school environments, such as the number of siblings in the home, parents' employment levels and high school graduation status, and the percentage of black students present in the classroom, are significantly associated with math achievement.


Abstract The ability of electrodeposited zinc-nickel alloy coatings to cathodically protect steel was studied in dilute chloride solutions. The potential distribution along steel strips partly electroplated with zinc-nickel alloys was determined, and the length of exposed steel that was held below the minimum protection potential (Eprot) was taken as a measure of the level of cathodic protection (CP) provided by the alloy coatings. The level of CP afforded by zinc alloy coatings was found to decrease with increasing nickel content. When nickel content was increased to ≈ ≥ 21 wt%, no CP was obtained. Surface analysis of uncoupled zinc-nickel alloys that were immersed in sodium chloride (NaCl) solutions showed the concentration of zinc decreased in the surface layers while the concentration of nickel increased, indicating that the alloys were susceptible to dezincification. The analysis of zinc-nickel alloy coatings on partly electroplated steel strips that were immersed in chloride solution showed a signif...

The high energy study of blazars above 100 MeV received a significant impetus from the observations of the EGRET instrument on board the Compton Gamma-Ray Observatory ( CGRO ) . EGRET has detected intense and variable gamma-ray emission from more than 66 active galaxies of the blazar type, establishing these as a class of high energy gamma ray sources. These results are complemented by the detection of very high energy emissior, (> 500 GeV) from 5 high-frequency peaked BL Lac objects ( HBLs) with ground-based at mospheric Cherenkov telescopes ( ACTs ) . In addition solar array experiments, like STACEE and CELESTE, have detected the blazar Mrk 421 for the first time below 200 GeV, and are continuing to observe other blazars at lower energy thresholds. Most EGRET blazars are not detected above 500 GeV due to cutoffs in the spectra because of photon absorption by the diffuse extragalactic background light. Blazar studies at 50-500 GeV is therefore important, not only to increase the number of blazars detected at these energies, but also to study the diffuse extragalactic background light. The low energy thresholds of current solar array ex periments, and the improved sensitivities of the next generations ACTs at even lower energies implies that the GeV-TeV studies of blazars will be a rapidly growing area of high energy astrophysics. This article selectively reviews results on GeV-TeV emission from blazars.


Agriculture is an important regional economic industry in Asian regions. Ensuring food security and stabilizing the food supply are a priority. In response to the frequent occurrence of natural disasters caused by global warming in recent years, the Agriculture and Food Agency (AFA) in Taiwan has conducted agricultural and food surveys to address those issues. To improve the accuracy of agricultural and food surveys, AFA uses remote sensing technology to conduct surveys on the planting area of agricultural crops. Unlike optical images that are easily disturbed by rainfall and cloud cover, synthetic aperture radar (SAR) images will not be affected by climatic factors, which makes them more suitable for the forecast of crops production. This research proposes a novel spatial-temporal neural network called a convolutional long short-term memory rice field classifier (ConvLSTM-RFC) for rice field classification from Sentinel-1A SAR images of Yunlin and Chiayi counties in Taiwan. The proposed model ConvLSTM-RFC is implemented with multiple convolutional long short-term memory attentions blocks (ConvLSTM Att Block) and a bi-tempered logistic loss function (BiTLL). Moreover, a convolutional block attention module (CBAM) was added to the residual structure of the ConvLSTM Att Block to focus on rice detection in different periods on SAR images. The experimental results of the proposed model ConvLSTM-RFC have achieved the highest accuracy of 98.08% and the rice false positive is as low as 15.08%. The results indicate that the proposed ConvLSTM-RFC produces the highest area under curve (AUC) value of 88% compared with other related models.


In this paper Element Free Galerkin Method is used and applied to the stress analysis problems where material has a tendency towards both elastoplastic and creep behavior. In doing so, following a brief description of the nonlinear constitutive formulation of elastoplastic and creep, a new technique for the numerical analysis of nonlinear problems has been constructed. The method has been examined in two different plates with and without a crack. The value of C*-integral has been used as a base for comparison of the creep results. A rather close agreement is seen between results of this work and the others.


The bioconversion of the hydrophobic and volatile limonene to perillic acid, a potential anticancer agent, by the yeast Yarrowia lipolytica was studied in two steps. Firstly, experimental design was used for process optimization using high-purity limonene as substrate and secondly orange essential oil containing 89.1% limonene was used as substrate under the previously optimized conditions. Limonene concentration and pH were identified by fractional factorial design as significant factors and were optimized by central composite design. Under optimized process conditions (0.16% (v/v) limonene; pH 6.9), the 24 h biotransformation process resulted in the accumulation of 0.368 g·L-1 of perillic acid corresponding to a molar yield of 23.1%. A subsequent substrate addition under the same reaction conditions doubled perillic acid concentration to 0.793 g·L-1 and a molar yield of 24.2%. The use of orange essential oil under the optimized reaction conditions increased both perillic acid accumulation and yield to 0.872 g·L-1 and 29.7%, respectively. The robustness of Y. lipolytica allowed the efficient biotransformation of a crude by-product of the citrus industry into a valuable fine chemical.


Objective:?To observe the clinic effect about the acute leukaemia (AL) children's strengthened chemical cure after using recombine human granule cell colony stimulating factor (rhG CSF). Methods:Injecting hyodermic rhG CSF(2~5 μg/kg) once after other day for 12 AL children whose leucocyte was not more than 1.0×10 9/L (marrow restrained period) and observe the blood sample. Stopping hyodermic injection when leucocyte was higher than 2.5×10 9/L. Noting the period of leucocyte's continuing reduction and the infection condition of AL children. At the same time checking marrow smear of whom had infantile cell in order to learn about marrow's condition. Comparing these with the former AL children without being injected in rhG CSF whose age, category and chemical cure scheme were same. Results:?The period of cured group (6±2.7 days) was obviously less than the compared group (13±3 days) in order to get the same results. The former just had less infection even no infection and most of these could go though the marrow restrained period safely. Otherwise the compared group had serious or diversified infection and the anti infection effect was poor. Six AL children's blood had infantile cell while being injected in rhG CSF, but after two weeks the reobservation shew that marrow was still in cushion period. Conclusion:?Injection rhG CSF(2~5 μg/kg) one day after other day could obviously shorten the marrow restrained period of AL children after strengthened chemical cure and could effectively avoid or control the following infection.


1,3-Dicarbonyls, such as 1,3-diketones and 1,3-ketoesters, react directly with elemental fluorine at room temperature to give the corresponding 2-fluoro- and, in some cases, 2,2-difluoro-compounds in high yield.


A procedure has been presented in this paper to identify the structural parameters, viz. mass and stiffness matrices, from modal test data for multistorey shear buildings. The first two orders of modal data have been used by other researchers to estimate the global matrices where they depend only on measurable points which are less than the total number of structural degrees of freedom. The above method has been refined here by using Holzer criteria along with other numerical methods to estimate the global mass and stiffness matrices of the structure. This shows the methodology to be more efficient and accurate. The reliability of the procedure has been shown by examples of multistorey buildings. Copyright © 2004 John Wiley & Sons, Ltd.

of Principles. If there is some point at which you cannot teach in accordance with and not contrary to that document, please indicate the changes you propose. It would be necessary to initiate procedures for a hearing before the Board of Trustees if amendments by this facuIty are proposed. Dr. Moody was not present for the meeting of the facuIty on December 3, 1979;but upon his return to the seminary, he forwarded to President McCall a letter dated February 8,1980, in which he made the following statement in his opening paragraph:


The ultraviolet, visible, and near‐infrared spectra of single‐crystal Nd2O3 and La2O3:Nd3+ observed at 10°, 80°, and 290°K, were analyzed. Over 300 absorption lines were assigned from the five crystalline Stark levels of the ground 4I92 state to over 20 excited J manifolds in each crystal. In thick crystals, transitions to many excited levels from the higher Stark levels of the 4I92 state were observed. The spectral assignments are compared with calculations of ``free‐ion'' energy levels and with the assignments of Y2O3:Nd3+. The parameters E1, E2, E3, and ξ are calculated for the three oxide crystals, and comparisons between observed and calculated energy levels are made. The significance of these parameters in comparison with those for Nd3+ in other crystals is discussed, and the effects of configuration interaction are pointed out.


This paper presents a reliability assessment of a substation, part of the Queensland transmission network in Australia. As part of a maintenance considerations, this study utilises the substation reliability assessment package STAREL to quantitatively compare the reliability improvement achieved by two circuit breaker reinforcement alternatives for Swanbank circuit breaker replacement or refurbishment. Substation reliability is interpreted on the basis of outage frequency and outage duration indices for each individual transmission line terminated in Swanbank 'B' substation. By considering the reliability indices in this paper with the cost associated conducted by POWERLINK Queensland, a Swanbank 'B' reinforcement alternative can be selected that optimises both transmission line security and the costs incurred in achieving it.

The clocking effect of a double stage compressor with positive bowed s tator in different axial gaps between rotor and stator rows was investigated in this paper.The traverse flow field was measured in detail at the second stator' s outlet.The experimental results show that clocking effect changes little while the axial gap reduces.The diffusion ability intensifies while the input torque increases.The efficiency increases firstly and then decreases.It means that ther e is an optimal axial gap.At the same time,the surge margin decreases while the axial gap reduces.


A numerical method is presented for simulating incompressible gas-liquid two-phase interfacial flows with immersed solid combining level set method with immersed boundary method,where level set technique is employed to capture the interface of gas-liquid flow,and immersed boundary method with a modified direct forcing scheme is developed to calculate the solid-fluid interaction force in a fixed Cartesian mesh.In the direct forcing scheme,an interpolation procedure is designed to evaluate the boundary force on the solid surface or inside the solid.Three different interfacial motion problems of bubble and droplet impacting onto a flat surface or solid sphere immersed in fluid are simulated.The details of the impacting process,such as spreading,recoiling of droplet or penetrating of bubble,are provided.The simulated results qualitatively coincide with the reported experimental observations,verifying the feasibility of the method.


ABSTRACT When a concentrated contact is lubricated at low speed by an oil-in-water emulsion, a film of pure oil typically separates the surfaces (stage 1). At higher speeds, starvation occurs (stage 2) and the film is thinner than would be expected if lubricated by neat oil. However, at the very highest speeds, film thickness increases again (stage 3), though little is known for certain about either the film composition or the mechanism of lubrication, despite some theoretical speculation. In this article, we report the film thickness in a ball-on-flat contact, lubricated by an oil-in-water emulsion, at speeds of up to 20 m/s, measured using a new high-speed test rig. We also investigated the sliding traction and the phase composition of the film, using fluorescent and infrared microscopy techniques. Results show that, as the speed is increased, starvation is followed by a progressive change in film composition, from pure oil to mostly water. At the highest speeds, a film builds up that has a phase composition similar to the bulk emulsion. This tends to support the "microemulsion" view rather than the "dynamic concentration" theory.


A mathematical (simulation) model is proposed for brushless direct current motor of telescope turntable. Stator windings of the motor are divided into three independent winding sections. Each winding zone is supplying from own inverter. These sections interact with a general permanent magnet rotor. Influence of stator windings asymmetry on motor static characteristics is studied.

A domain-specific approach to social judgments is presented. Epistemologica! is sues are considered that are informed by identifying and defining domain boundaries. It is proposed that analyses of systems of knowledge are necessary for study of development and behavior. Research is reviewed in support of a model including moral, social-conventional, and psychological concepts, as well as a distinction between conceptual and informational knowledge. Criticisms of the domain approach are considered. Some criticisms are based on the miscon ception that examples of category mixture invalidate domain demarcations. Other criticisms are addressed through propositions regarding the role of domain-specificity in analyses of cultural influences.


of the Gallatin piece is not documented,' Parlasca's assignment to Antinoopolis (based on the characteristic laterally-stepped panel shape and on stylistic criteria)s is here confirmed by its attribution to the artist of the Dijon portrait. Beyond the striking similarity of overall style, particular idiosyncrasies evident in their facial representations mark the two portraits as the work of the same hand. Among these may be mentioned the lips: long and narrow in each case and noticeably crooked, slanting downward to the subject's right. Lips of this distinctive pattern are to be found on no other extant Antinoopolitan portrait. The neck of each seems a lifeless cylinder, poorly integrated with the head. The curved horizontal emphasis of the neck's roundness is significant: the juncture at the chest is unconvincing, as if each neck were attached to the torso at an abrupt angle. In the area of the eyes, one notes the lines at the junctures above the upper lids, identically arched and similarly placed below "penciled" brows. The leading edges of the upper lids consist in each case of thick dark strokes, which were probably meant to suggest lashes but which in fact merely highlight their absence. The lower lid of each eye appears as a thick, fleshy ridge, shaded sharply below, again with no lashes represented. But the most conclusive evidence for attribution, and the hallmark of Painter J, is to be found in the identical translations of the forehead-hairline relationship. To each portrayal has been added a distinctive light border at the hairline. While presumably intended to suggest a shadow which the hair projects onto the forehead, this device shows little correspondence to the actual light source-apparent in each case at subject's right-and even extends up into the hair, with the

Background: Folk ayurvedic pratitioners are the primary health care providers in rural population in Bangladesh.in Bengali term; these medicinal practitioners are known as "Kavirajes". Ayurvedic studies are an important feature of traditional medicinal practices in Bangladesh. The major characteristic that separates the folk medicinal practitioners from other systems of existing medicinal practices is their almost exclusive use of simple preparations of medicinal plants for treatment of various ailments. The objective of this study was to make a comparative analysis of reported ethnomedicinal uses of plants used by a folk medicinal practitioner (Kaviraj) of paramtala village of Muradnagar Upazila in comilla district, Bangladesh. Methods: Interviews of the Kaviraj were carried out with the help of a semistructured questionnaire and the guided field-walk method. Results: The Kaviraj used 12 plants distributed into 10 families in his formulations. Available ethnomedicinal and scientific reports show that the plants used by the Kaviraj can be validated in their uses on the basis of either ethnomedicinal consensus or


The paper presents results of tests of mechanical properties, hardness measurements, macro-and microstructures of welded joints austenitic and austenitic-ferritic steel with high manganese and aluminium content meant for automotive industry. Tests were conducted on flat sheets made of steel X20MnAl18-3 and X55MnAl25-5. Tested welded joints were ruptured in tensile strength test in all cases inside the weld which is connected with lower resistance to stretching of welded joints in comparison with resistance of joined steels. Resistance to stretching of tested samples, regardless of the method of welding, is on a similar level.

In this paper, the concept of an LED driver based on minimal power processing is presented. By regulating the power flow using semiconductor switches, the required minimal power processing can be achieved, which in turn reduces storage capacitance and extends the lifespan of LED driver. In contrast to a two-stage LED driver, the DC-DC converter handles a part of the total power in the minimal power processing design. This will increase the overall performance of the system. In addition, the double line frequency power that is inevitable for any AC-DC conversion system is reduced. The DC output power can be match with the AC input ripple power using the correct switching timings of semiconductor switches. Thus, long life film capacitors can be used in place of electrolytic capacitors. To get the required minimal power processing, power factor correction, and constant output current increases the design and control complexity, and a number of components. A 38W simulation model is implemented using PSIM simulation. The results validate the performance of the system in terms of power factor, constant output current, and peak efficiency.


Forest litter is a fuel component that is important for the propagation of fire. Data describing fuel load, structure and fuel condition were gathered for two sites of Sydney Coastal Dry Sclerophyll Forest, a common vegetation type in the Sydney Basin, Australia. Surface litter from the sites was sorted into its constituent components and used to establish which component or mixture of components were the most flammable using several metrics. A general blending model was used to estimate the effect the different mixtures had on the response of the flammability metrics and identify non-additive effects. Optimisation methods were applied to the models to determine the mixture compositions that were the most or least flammable. Differences in the flammability of the two sites were significant and were driven by Allocasuarina littoralis. The presence of A. littoralis in litter mixtures caused non-additive effects, increasing the rate of flame spread and flame height non-linearly. We discuss how land managers could use these models as a tool to assist in prioritising areas for hazard reduction burns and how the methodology can be extended to other fuel conditions or forest types.


In modern agriculture the soy has a place of prominence, which is guaranteed for the high productivity, excellent yield in the market and mainly in the exportation of grains. It s known that in order to achieve a good produce an adequate plan of production and adequate techniques on the preparation of the soil according to its region of the country. This work was developed in the Universidade Estadual Paulista, Faculdade de Ciencias Agrarias e Veterinarias, Campus de Jaboticabal, SP, with the objective of analyze the effect of different soil tillage in the soybean crop ( Glycine max (L.) Merrill) in a Oxisoil, being they conventional (disc plow + two soft harrowings, moldboard plow and two soft harrowings, heavy disc harrow + soft harrowing), 2 reduced (chiselplow + softharrowing, chiselplow only) and no tillage, resulting in 6 treatments with 4 repetitions. The water level in the ground did not have significant differences between the treatments. In the superficial layer (0-5 cm) the no tillage presented greater resistance to the penetration in relation to the treatments mondboard plough and two harrowings and chiselplow and harrow. The agronomical characteristics of the soybean crop are not influenced by the studied treatments.
