Full Text Available Abstract Background Overall reproductive performance of dairy herds is monitored by various indicators. Most of them do not consider all eligible animals and do not consider different management strategies at farm level. This problem can be alleviated by measuring the proportion of pregnant cows by specific intervals after their calving date or after a fixed time period, such as the voluntary waiting period. The aim of this study was to evaluate two reproductive performance indicators that consider the voluntary waiting period at the herd. The two indicators were: percentage of pregnant cows in the herd after the voluntary waiting period plus 30 days (PV30 and percentage of inseminated cows in the herd after the voluntary waiting period plus 30 days (IV30. We wanted to assess how PV30 and IV30 perform in a simulation of herds with different reproductive management and physiology and to compare them to indicators of reproductive performance that do not consider the herd voluntary waiting period. Methods To evaluate the reproductive indicators we used the SimHerd-program, a stochastic simulation model, and 18 scenarios were simulated. The scenarios were designed by altering the reproductive management efficiency and the status of reproductive physiology of the herd. Logistic regression models, together with receiver operating characteristics (ROC, were used to examine how well the reproductive performance indicators could discriminate between herds of different levels of reproductive management efficiency or reproductive physiology. Results The logistic regression models with the ROC analysis showed that IV30 was the indicator that best discriminated between different levels of management efficiency followed by PV30, calving interval, 200-days not-in calf-rate (NotIC200, in calf rate at100-days (IC100 and a fertility index. For reproductive physiology the ROC analysis showed that the fertility index was the indicator that best discriminated

Full Text Available The main objective of the study was to analyze and assess the changes in motor skill level of football players after the period of special preparation. This goal was accomplished by discussing theoretical information on the above issues as well as the results of a study conducted jointly with a group of 54 trainers at Flisak Złotoria Club (18 football players aged 11-12, 13-17 and over 17 years. In the course of the research it was shown that the football training at Flisak Złotoria in the special subperiod contributed to a slight improvement in general level and special fitness. Irregularities have been observed in young men's swing and seniors' swing, but due to the marginal nature of negative changes they should not cause a negative assessment of the quality of training in the examined club (though an in-depth analysis of training programs is required for the preparatory period. It also seems reasonable to look for solutions that will increase the efficiency of special fitness training. There was no constant correlation between the age of the respondents and the results of the training. In the course of the research conducted among youngsters, juniors and seniors, it was stated above all that the special preparation sub-period had a very limited but positive impact on the overall fitness level of football players, as confirmed by the improvement in the average scores obtained in 7 out of 9 Exercises. The fact that, as the empirical data show, the marginal reduction of the Seniors' speed over short distances (a decrease of the average running time of 15 meters by 0.21% and the youthfulness (decrease of the length of the jump by 0.99 %.

Clinical observations and first person accounts of living with autism suggest that individuals with autism are highly motivated to engage in special interests, and that these interests remain important throughout life. Previous research assessing special interests has mainly focused on parental reports of children with autism spectrum conditions (ASC). To better understand the significance of and motivations for engaging in special interests it is essential to use self-report ratings. This paper aims to systematically explore the motivations for engagement in special interests, and whether these differ in adults with ASC, first-degree relatives and general population controls. The Special Interest Motivation Scale (SIMS) was developed to assess motivation to engage in special interests. The internal structure of this scale was evaluated using factor analysis, and mean scores on the SIMS factors were subsequently compared across individuals with autism, parents and general population controls. Factor analysis indicated a 20-item SIMS containing five factors assessing Personal life values and goals; Intrinsic interest and knowledge; Prestige; Engagement and "flow" and Achievement. Individuals with autism were more motivated by Intrinsic interest and knowledge and by Engagement and flow than controls. The 20-item SIMS is a quick to administer measure that provides a reliable description of motivation to engage in special interests. This study indicates that individuals with ASC are highly motivated to engage in their special interest, and are more motivated than controls by intrinsic motivational factors, some of which are associated with positive affect. This has implications for research and clinical practice.

Hasan, Mohammd; Mandal, Bhabani Prasad

2018-04-01

In this paper we introduce the concept of super periodic potential (SPP) of arbitrary order n, n ∈I+, in one dimension. General theory of wave propagation through SPP of order n is presented and the reflection and transmission coefficients are derived in their closed analytical form by transfer matrix formulation. We present scattering features of super periodic rectangular potential and super periodic delta potential as special cases of SPP. It is found that the symmetric self-similarity is the special case of super periodicity. Thus by identifying a symmetric fractal potential as special cases of SPP, one can obtain the tunnelling amplitude for a particle from such fractal potential. By using the formalism of SPP we obtain the close form expression of tunnelling amplitude of a particle for general Cantor and Smith-Volterra-Cantor potentials.

The HYdrological cycle in the Mediterranean EXperiment (HyMeX) is intended to improve the capabilities of predicting high-impact weather events. Within its framework, the aim of the first special observation period (SOP1), 5 September to 6 November 2012, was to study heavy precipitation events and flash floods. Here, we present high-impact weather events over Croatia that occurred during SOP1. Particular attention is given to eight intense observation periods (IOPs), during which high precipitation occurred over the eastern Adriatic and Dinaric Alps. During the entire SOP1, the operational model forecasts generally well represented medium intensity precipitation, but heavy precipitation was frequently underestimated by the ALADIN model at an 8 km grid spacing and was overestimated at a higher resolution (2 km grid spacing). During IOP2, intensive rainfall occurred over a wider area around the city of Rijeka in the northern Adriatic. The short-range maximum rainfall totals were the largest ever recorded at the Rijeka station since the beginning of measurements in 1958. The rainfall amounts measured in intervals of 20, 30 and 40 min were exceptional, with return periods that exceeded a thousand, a few hundred and one hundred years, respectively. The operational precipitation forecast using the ALADIN model at an 8 km grid spacing provided guidance regarding the event but underestimated the rainfall intensity. An evaluation of numerical sensitivity experiments suggested that the forecast was slightly enhanced by improving the initial conditions through variational data assimilation. The operational non-hydrostatic run at a 2 km grid spacing using a configuration with the ALARO physics package further improved the forecast. This article highlights the need for an intensive observation period in the future over the Adriatic region to validate the simulated mechanisms and improve numerical weather predictions via data assimilation and model improvements in descriptions

Full Text Available The aim of this work was the study of the special features of intraoperative and early postoperative period course in patients with gastroesophageal reflux disease after antireflux surgery carried out from laparoscopic and traditional laparotomy approach. Materials and methods. There were analyzed the results of examination and surgical treatment of 136 patients with gastroesophageal reflux disease treated at SI A.A. Shalimov “National Institute of surgery and transplantology” NAMSU from 2005 to 2015 year. The main group included 93 patients who underwent laparoscopic surgery, the control one – 43 patients who underwent surgery by traditional open method.There was carried out monitoring of the main parameters of vital functions every three hours after surgery, recovery terms of intestine peristaltic activity, pain syndrome intensity, analyzed the dynamics of changes of the typical GERD complaints, its intensity, the development of early postoperative complications. The results of research. Duration of laparoscopic surgeries did not differ from the open ones but intraoperative hemorrhage and prolonged artificial pulmonary ventilation, postoperative patient day were less than in the control group. At the same time the main parameters of the organism vital functions (systolic and diastolic arterial pressure, respiration rate, heart rate, oxygen blood saturation were better in patients of the main group.In the group of patients operated by laparascopic approach intensity and duration of pain syndrome were less than in patients operated by open approach and also was noticed an early activation and recovery of intestinal peristalsis in these patients.Conclusions. Both laparoscopic and open approaches at antireflux surgeries in early postoperative period are effective. The received data testifies to the less traumatism, less duration of recovery period at videoendoscopic surgeries that by-turn decreases the risk of postoperative complications

Full Text Available During the Abbasid period, Muslim culture and civilization was at its zenith. It was a period of economic prosperity and of great intellectual awakening. The Abbasid Caliphate provided the most congenial atmosphere for the advancement of learning and education. In fact, the reign of Mamun-ar-Rashid who has deservedly been called the 'Augustus of Arabs' formed the culmination of the intellectual achievements of the Muslims. He was followed by a brilliant succession of Caliphs who continued his work. Muslims gained access to the Greek medical knowledge of Hippocrates, Discords, and Galen through the translations of their works in the seventh and eighth centuries. These initiatives by Muslims could be seen in the different aspects of the healing arts that were developed. The translation movement of the twelfth century in Latin Europe affected every known field of science, none more so than medicine. The present paper is an attempt to give a detailed contribution of Muslims to science with special reference to medicine. It is in this context the present paper has been analyzed.

Semi-annual report on strategic special nuclear material inventory differences

International Nuclear Information System (INIS)

1981-08-01

This eighth periodic semiannual report of inventory differences covers the second six months of fiscal year 1980 (April 1, 1980, through September 30, 1980), for the Department of Energy (DOE) and DOE contractor facilities possessing significant quantities of strategic special nuclear material. Strategic special nuclear material is plutonium or uranium-233 or uranium-235 in material whose uranium-235 content is 20 percent or greater (known as highly enriched uranium). A significant quantity is either 2 kilograms of plutonium or uranium-233 or 5 kilograms of uranium-235 in highly enriched uranium or the appropriate weighted combination. All Inventory Differences reported here have been analyzed, investigated when necessary, and resolved. These data and explanations, together with the absences of physical indications of any theft attempt, support a finding that during this period no theft or diversion of strategic special nuclear material has occurred

Periodicity of the stable isotopes

CERN Document Server

Boeyens, J C A

2003-01-01

It is demonstrated that all stable (non-radioactive) isotopes are formally interrelated as the products of systematically adding alpha particles to four elementary units. The region of stability against radioactive decay is shown to obey a general trend based on number theory and contains the periodic law of the elements as a special case. This general law restricts the number of what may be considered as natural elements to 100 and is based on a proton:neutron ratio that matches the golden ratio, characteristic of biological and crystal growth structures. Different forms of the periodic table inferred at other proton:neutron ratios indicate that the electronic configuration of atoms is variable and may be a function of environmental pressure. Cosmic consequences of this postulate are examined. (author)

Significant calendar period deviations in testicular germ cell tumors indicate that postnatal exposures are etiologically relevant.

Speaks, Crystal; McGlynn, Katherine A; Cook, Michael B

2012-10-01

The current working model of type II testicular germ cell tumor (TGCT) pathogenesis states that carcinoma in situ arises during embryogenesis, is a necessary precursor, and always progresses to cancer. An implicit condition of this model is that only in utero exposures affect the development of TGCT in later life. In an age-period-cohort analysis, this working model contends an absence of calendar period deviations. We tested this contention using data from the SEER registries of the United States. We assessed age-period-cohort models of TGCTs, seminomas, and nonseminomas for the period 1973-2008. Analyses were restricted to whites diagnosed at ages 15-74 years. We tested whether calendar period deviations were significant in TGCT incidence trends adjusted for age deviations and cohort effects. This analysis included 32,250 TGCTs (18,475 seminomas and 13,775 nonseminomas). Seminoma incidence trends have increased with an average annual percentage change in log-linear rates (net drift) of 1.25 %, relative to just 0.14 % for nonseminoma. In more recent time periods, TGCT incidence trends have plateaued and then undergone a slight decrease. Calendar period deviations were highly statistically significant in models of TGCT (p = 1.24(-9)) and seminoma (p = 3.99(-14)), after adjustment for age deviations and cohort effects; results for nonseminoma (p = 0.02) indicated that the effects of calendar period were much more muted. Calendar period deviations play a significant role in incidence trends of TGCT, which indicates that postnatal exposures are etiologically relevant.

To determine the effect of transportation during periods of high ambient temperature on physiologic and behavioral indices of beef heifers. 20 heifers (mean body weight, 217.8 kg). Ten heifers were transported 518 km when the maximum ambient temperature was ≥ 32.2°C while the other 10 heifers served as untransported controls. Blood samples were collected from transported heifers at predetermined intervals during the transportation period. For all heifers, body weights, nasal and rectal temperatures, and behavioral indices were measured at predetermined intervals for 3 days after transportation. A week later, the entire process was repeated such that each group was transported twice and served as the control twice. Transported heifers spent more time near the hay feeder on the day of transportation, had lower nasal and rectal temperatures for 24 hours after transportation, and spent more time lying down for 2 days after transportation, compared with those indices for control heifers. Eight hours after transportation, the weight of transported heifers decreased 6%, whereas that of control heifers increased 0.6%. At 48 hours after initiation of transportation, weight, rectal temperature, and time spent at various pen locations did not differ between transported and control heifers. Cortisol concentrations were higher 4 hours after initiation of transportation, compared with those determined just prior to transportation. Results indicated transportation during periods of high ambient temperatures caused transient changes in physiologic and behavioral indices of beef heifers.

Although homelessness is inherently associated with social exclusion, homeless individuals are rarely included in conventional studies on social exclusion. Use of longitudinal survey data from a cohort study on homeless people in four major Dutch cities ( n  = 378) allowed to examine: changes in indicators of social exclusion among homeless people over a 2.5-year period after reporting to the social relief system, and associations between changes in indicators of social exclusion and changes in psychological distress. Multinomial logistic regression analysis was applied to investigate the associations between changes in indicators of social exclusion and changes in psychological distress. Improvements were found in various indicators of social exclusion, whereas financial debts showed no significant improvement. Changes in unmet care needs, health insurance, social support from family and relatedness to others were related to changes in psychological distress. This study demonstrated improvements in various indicators of social exclusion among homeless people over a period of 2.5 years, and sheds light on the concept of social exclusion in relation to homelessness.

Near-optimality of special periodic protocols for fluid models of single server switched networks with switchover times

Science.gov (United States)

Matveev, A. S.; Ishchenko, R.

2017-11-01

We consider a generic deterministic time-invariant fluid model of a single server switched network, which consists of finitely many infinite size buffers (queues) and receives constant rate inflows of jobs from the outside. Any flow undergoes a multi-phase service, entering a specific buffer after every phase, and ultimately leaves the network; the route of the flow over the buffers is pre-specified, and flows may merge inside the network. They share a common source of service, which can serve at most one buffer at a time and has to switch among buffers from time to time; any switch consumes a nonzero switchover period. With respect to the long-run maximal scaled wip (work in progress) performance metric, near-optimality of periodic scheduling and service protocols is established: the deepest optimum (that is over all feasible processes in the network, irrespective of the initial state) is furnished by such a protocol up to as small error as desired. Moreover, this can be achieved with a special periodic protocol introduced in the paper. It is also shown that the exhaustive policy is optimal for any buffer whose service at the maximal rate does not cause growth of the scaled wip.

In recent years, extreme rainfall events occur frequently and induced serious landslides and debris flow disasters in Taiwan. The instability indices will differ when using landslide maps of different time periods. We analyzed the landslide records during the period year, 2008 2012, the landslide area contributed 0.42% 2.94% of the total watershed area, the 2.94% was caused by the typhoon Morakot in August, 2009, which brought massive rainfall in which the cumulative maximum rainfall was up to 2900 mm. We analyzed the instability factors including elevation, slope, aspect, soil, and geology. And comparing the instability indices by using individual landslide map of 2008 2012, the landslide maps of the union of the five years, and interaction of the five years. The landslide area from union of the five years contributed 3.71%,the landslide area from interaction of the five years contributed 0.14%. In this study, Kriging was used to establish the susceptibility map in selected watershed. From interaction of the five years, we found the instability index above 4.3 can correspond to those landslide records. The potential landslide area of the selected watershed, where collapses occur more likely, belongs to high level and medium-high level; the area is 13.43% and 3.04% respectively.

The purpose of this study was to perform a comprehensive audit of dental treatment provided to special needs patients (SNP) under general anesthesia (GA) over a ten-year period. Special needs patients who received dental treatment under GA as an in-patient at Queen Mary Hospital, Hong Kong SAR during the time period January 2002 and December 2011 were included in the study. The study population was divided into three groups, based on age (12 years). One-way ANOVA was used to evaluate the effect of "age group" on duration of treatment, post-recovery time, treatment procedures and utilization of different restorative materials. Kappa statistics were used for intra-examiner reliability. A total of 275 patients (174 males and 101 females) were included in the study. The mean age of the patients at the time they received GA was 12.37±10.18 years. Dental procedures performed were mostly restorative in nature (47%). The >12 years group had significantly shorter treatment duration (pdifference in post-operative recovery time was observed among the three age groups (p>0.05).

2015-01-01

The behaviour of Indian stock markets has a persistent close association with the behaviour of American stock exchange. The present work is an effort in this direction and the purpose of the present work is to investigate the periodicity of the two prime Indian stock market indices viz. SENSEX and NIFTY and the prime American stock market indices viz. DOW-JONES and S&P500. To serve the present purpose we have here used SENSEX logarithmic daily close data during the period from 1st January, 1990 to 31st December, 2013, NIFTY logarithmic daily close data during the period from 3rd July, 1990 to 31st December, 2013, DOW-JONES logarithmic daily close data during the period from 10th January, 1928 to 31st December, 2013 and S&P500 logarithmic daily close data during the period 3rd January, 1950 to 31st December, 2013. For the present analysis we have first used double exponential smoothing on all the four time series in order to remove the trend and next we have generated monthly averages of the smoothed time series in order to remove the irregular fluctuations. At the final stage Ferraz-Mello method of date-compensated discrete Fourier transform (DCDFT) has been applied on the present four double-smoothed monthly averaged time series. Study reveals periods for SENSEX of 11, 53 and 142 months; for NIFTY periods of 22, 38, 52 and 139 months; for DOW-JONES periods of 23, 25, 27, 30, 59, 107, 138, 194 and 494 months and for S&P500 periods of 28, 66, 74, 149 and 384 months. With this specific periodic behaviour we have also observed some pseudo-periods in the present four financial time series which certainly adds to the uncertainty in the process of prediction for the same

Brazing of special metallic materials and material combinations using a special material

International Nuclear Information System (INIS)

Lison, R.

1981-01-01

The special materials include metals of groups IVa, Va and VIa of the periodic tables and their alloys. Their particular properties have won them applications in many highly specialized industries. For these materials to be used, mastery of thermal joining methods appropriate to their characteristics is necessary. High-temperature brazing is one such method for joining special materials. This paper presents variants of this technique suitable for each individual special material. Compatibility tests between various brazing metals and various special materials have been carried out by simulating the temperature/time cycle involved in brazing procedures. Special materials are relatively expensive, and their special properties are not required at every point in a structure: elsewhere they can be replaced by a different special material or by other metals or alloys. This means that joints must be made between two special materials or between a special material and a conventional material. When certain conditions are fulfilled, such joins can be made by high-temperature brazing. This paper also shows the extent to which the geometry of the join determines the choice of process. Example of applications are also given. (orig.)

Objectives Little is known regarding incidence and recurrence of sickness absence in self-employed. The primary aim of this study was to evaluate the influence of the number of prior episodes of sickness absence on the risk of subsequent periods of sickness absence in higher educated self-employed. Methods In a historic register study based on the files of a Dutch private disability insurance company all sickness absence periods of 30 days or more were analysed. Results A total of 15,868 insured persons contributed 141,188 person years to the study. In total, 5608 periods of sickness absence occurred during follow-up. The hazard of experiencing a new period of sickness absence increased with every previous period, ranging from a hazard ratio of 2.83 in case of one previous period of sickness absence to a hazard ratio of 6.72 in case of four previous periods. This effect was found for both men and women and for all diagnostic categories of the first period of sickness absence. Conclusions Our study shows that for all diagnostic categories the hazard of experiencing a recurrence of sickness absence is appreciably higher than for experiencing a first episode. This suggests that this increased hazard may be related to the occurrence of sickness absence itself rather than related to characteristics of the insured person or of the medical condition. These findings could indicate that sickness absence periods may have a scarring effect on the self-employed person experiencing the sickness absence. PMID:27213963

Period mappings were introduced in the sixties [4] to study variation of complex structures of families of algebraic varieties. The theory of tautological systems was introduced recently [7,8] to understand period integrals of algebraic manifolds. In this paper, we give an explicit construction of a tautological system for each component of a period mapping. We also show that the D-module associated with the tautological system gives rise to many interesting vanishing conditions for period integrals at certain special points of the parameter space.

Possible Rivaroxaban Failure during the Postpartum Period.

Rudd, Kelly M; Winans, Amanda R McFee; Panneerselvam, Narmadha

Rivaroxaban, a factor Xa inhibitor, is a direct-acting oral anticoagulant (DOAC) indicated for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and for reducing the risk of DVT and PE recurrence. To our knowledge, no data are presently available to guide DOAC dosing in the postpartum period when pharmacokinetic and pharmacodynamic changes induced by pregnancy have an impact on drug clearance and increase hypercoagulability for a period of 6-8 weeks after delivery. We describe the case of a 35-year-old postpartum woman who presented to the emergency department with a diagnosis of a new multiple segmental PE 5 days after starting rivaroxaban therapy for a diagnosis of DVT. No precipitating cause, including noncompliance, was identified as a source of thrombosis embolization or extension. The patient was admitted, a heparin infusion was started for the management of PE, and rivaroxaban was discontinued. She was transitioned to enoxaparin 1 mg/kg (90 mg) subcutaneously every 12 hours the next day, bridged to warfarin, and discharged home on the overlapping regimen with close follow-up by the pharmacist-managed outpatient Anticoagulation Management Service. To our knowledge, this is the first case report of potential failure associated with rivaroxaban therapy in the postpartum period, possibly due to pharmacokinetic alterations seen in the postpartum period contributing to decreased drug exposure, yielding reduced anticoagulant efficacy. Clinicians should carefully weigh the risks and benefits of DOAC therapy in postpartum patients or other special populations requiring anticoagulation therapy. This report also highlights the need for further research identifying the impact of pharmacokinetic changes induced by special populations and the need to develop monitoring assays for such clinical situations. © 2015 Pharmacotherapy Publications, Inc.

Variation in rhinarium temperature indicates sensory specializations in placental mammals.

Science.gov (United States)

Gläser, Nele; Kröger, Ronald H H

2017-07-01

The rhinarium, a specialized nose-tip characterized by an area of naked and wet skin around the nostrils, is a typical mammalian structure. The type and amount of innervation suggests a sensory role and morphological diversity implies so far unidentified species-specific functional specializations. Rhinaria also vary in temperature and this may be related to the functions of these sensory organs. We performed a comparative study on rhinarium temperature in order to learn more about possible correlations with phylogeny and ecology. We have concentrated on terrestrial carnivorans and large herbivores, but also investigated a number of other species, some of them lacking typical rhinaria. We used infrared (IR) thermography to determine nose skin temperatures from safe distances and without interfering with the animals' behavior. In all groups studied, the temperature of the rhinarium/nose-tip decreased with decreasing ambient temperature. At all ambient temperatures, rhinarium temperature was lower, by 9-17°C, in carnivorans compared to herbivores. Glires (rodents and lagomorphs), haplorrhine primates, and omnivorous Perisso- and Artiodactyla were intermediate. In strepsirrhine primates, rhinarium temperature was similar to ambient temperature. Our findings in Strepsirrhini are consistent with the hypothesis that their rhinaria have an indirect role in chemical communication. Warm rhinaria in herbivores suggest a tactile function, while the low skin temperatures on carnivoran rhinaria may make the skin particularly sensitive to warming. Copyright © 2017 Elsevier Ltd.

When becoming a specialist, learning-through-service plays a significant role. The workplace affords good opportunities for learning, but the service-learning period may also impose stress on phycisians in specialization training. In medical work, social support has proved to be a very important factor in managing stress. Social support may afford advantages also for learning and professional identity building. However, little was known about how social support is perceived by doctors in specialization training. This study aimed to understand the perceptions of physicians in specialization training regarding social support communication in their workplace during their learning-through-service period. The study was conducted qualitatively by inductively analyzing the physicians' descriptions of workplace communication. The dataset included 120 essays, 60 each from hospitals and primary healthcare centres. Physicians in specialization training explained the need of social support with the responsibilities and demands of their clinical work and the inability to control and manage their workloads. They perceived that social support works well for managing stress, but also for strengthening relational ties and one's professional identity. A leader's support was perceived as being effective, and both senior and junior colleagues were described as an important source of social support. Also co-workers, such as the individual nurse partner with whom one works, was mentioned as an important source of social support. The results of this study indicate that social support works at the relational and identity levels, which is due to the multi-functional nature of workplace communication. For example, consultation functions as situational problem-solving, but also the tone of social interaction is meaningful. Thus, strengthening one's professional identity or collegial relationships requires further attention to workplace communication. Abbreviations PiST: Physician in

The aim of the study was to investigate the career choices, location preferences and criteria among medical students in Greece. We applied a questionnaire-based analysis using a sample of 591 students of four out of seven Greek Medical Schools. The sample included students of all academic years. The vast majority of students wish to specialize (97.6%), while general practice gathered a very low percentage (1.7%). The scientific challenge (61.4%) and interaction with patients (60.6%) seem to be the major influencing factors for most of the students' specialty preferences, whilst less common variables influencing career choice are the high demand/supply ratio for certain health services (40.4%), the income potential (31.4%), the active tempo (26.2%) and prestige (15%). 70.3% of those asked consider the possibility of specializing abroad. The low concern of Greek medical students for general practice reveals today's drastic deficiency in Greek primary health care. Such a situation will escalate, unless targeted strategies to produce more general practitioners are adopted. Furthermore, the results reflect a lower education and organizing level urging students to specialize abroad. The National Health System (NHS) should be reformed towards a rationalistic distribution of the medical specialties and medical workforce.

Entropy method of measuring and evaluating periodicity of quasi-periodic trajectories

Science.gov (United States)

Ni, Yanshuo; Turitsyn, Konstantin; Baoyin, Hexi; Junfeng, Li

2018-06-01

This paper presents a method for measuring the periodicity of quasi-periodic trajectories by applying discrete Fourier transform (DFT) to the trajectories and analyzing the frequency domain within the concept of entropy. Having introduced the concept of entropy, analytical derivation and numerical results indicate that entropies increase as a logarithmic function of time. Periodic trajectories typically have higher entropies, and trajectories with higher entropies mean the periodicities of the motions are stronger. Theoretical differences between two trajectories expressed as summations of trigonometric functions are also derived analytically. Trajectories in the Henon-Heiles system and the circular restricted three-body problem (CRTBP) are analyzed with the indicator entropy and compared with orthogonal fast Lyapunov indicator (OFLI). The results show that entropy is a better tool for discriminating periodicity in quasiperiodic trajectories than OFLI and can detect periodicity while excluding the spirals that are judged as periodic cases by OFLI. Finally, trajectories in the vicinity of 243 Ida and 6489 Golevka are considered as examples, and the numerical results verify these conclusions. Some trajectories near asteroids look irregular, but their higher entropy values as analyzed by this method serve as evidence of frequency regularity in three directions. Moreover, these results indicate that applying DFT to the trajectories in the vicinity of irregular small bodies and calculating their entropy in the frequency domain provides a useful quantitative analysis method for evaluating orderliness in the periodicity of quasi-periodic trajectories within a given time interval.

Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

Knowledge-based competitiveness indices and its connection with energy indices

Full Text Available Knowledge-based economy has become a major trend in international society in the 21st century. However, today’s strategies place a greater emphasis on sustainability than in the past, while continuing to emphasize the importance of education and its connection with labour market. There has been a re-orientation, where resource, eco-efficiency and innovation have become major elements for achieving national objectives and a relevant level of competitiveness. This article deals with 30 indices, which define the competitiveness of a specific economy, and involve knowledge parameters. They are classified into four main categories and one special category. They are then analysed regarding the participation of Serbia and their availability. The main focus of this paper is to give detailed analyses of energy indices, as a special category of knowledge indexes. It has been shown that Serbia, in many cases, was not included in the study analysis or that there was insufficient information about Serbia’s position. This article shows that only a part of the presented indices includes Serbia. It is concluded that a new, revised model is needed that will include more exact indicators.

Impact of the infectious period on epidemics

Science.gov (United States)

Wilkinson, Robert R.; Sharkey, Kieran J.

2018-05-01

The duration of the infectious period is a crucial determinant of the ability of an infectious disease to spread. We consider an epidemic model that is network based and non-Markovian, containing classic Kermack-McKendrick, pairwise, message passing, and spatial models as special cases. For this model, we prove a monotonic relationship between the variability of the infectious period (with fixed mean) and the probability that the infection will reach any given subset of the population by any given time. For certain families of distributions, this result implies that epidemic severity is decreasing with respect to the variance of the infectious period. The striking importance of this relationship is demonstrated numerically. We then prove, with a fixed basic reproductive ratio (R0), a monotonic relationship between the variability of the posterior transmission probability (which is a function of the infectious period) and the probability that the infection will reach any given subset of the population by any given time. Thus again, even when R0 is fixed, variability of the infectious period tends to dampen the epidemic. Numerical results illustrate this but indicate the relationship is weaker. We then show how our results apply to message passing, pairwise, and Kermack-McKendrick epidemic models, even when they are not exactly consistent with the stochastic dynamics. For Poissonian contact processes, and arbitrarily distributed infectious periods, we demonstrate how systems of delay differential equations and ordinary differential equations can provide upper and lower bounds, respectively, for the probability that any given individual has been infected by any given time.

Some climatic indicators in the period A.D. 1200-1400 in New Mexico

Leopold, Luna Bergere; Leopold, Estella B.; Wendorf, F.

1963-01-01

Three centuries before Columbus landed in America, the alluvial valleys of the south-western United States teemed with activity. The indigenous peoples had been building for 300 years a culture centred around community life based on flood-water farming and on hunting. A large number of pueblos had developed on sites earlier occupied by pit-house people. Community organization had brought advances in the ceramic and decorative arts, and changes in these artistic activities were sufficiently rapid that accurate chronologies have become available through the work of archaeologists during the twentieth century. These chronologies were at first unrelated to absolute dates, but the excavations of the 1920s at Chaco Canyon (New Mexico) provided the materials through which absolute dates could be established. This was accomplished by matching the changes in tree-ring width backward in time from living trees through successively older samples. Trees overlapping in age provided, by unique successions of distinctive tree-ring widths, a calendar by which individual logs could be dated. Beams found in the excavations at Chaco Canyon gave the first material by which the cultural developments culminating about A.D. 1300 could be dated.As a result of the time sequence provided by the tree-ring calendar, the dates within which different pottery types were developed could be accurately established. The dates of pottery types have been checked at a sufficiently large number of sites throughout the south-western United States that absolute dating of a large number of distinctive patterns can be considered unassailable. The sequence of tree-ring widths gives some climatic indications of great interest both to archaeologists and to climatologists. A relatively large number of logs spanning the period from A.D. 1200 to 1300 and, in particular, the years between 1276 and 1299, indicate that this period was generally characterized by smaller tree-ring widths than in the centuries

Detecting periodicities with Gaussian processes

Directory of Open Access Journals (Sweden)

Nicolas Durrande

2016-04-01

Full Text Available We consider the problem of detecting and quantifying the periodic component of a function given noise-corrupted observations of a limited number of input/output tuples. Our approach is based on Gaussian process regression, which provides a flexible non-parametric framework for modelling periodic data. We introduce a novel decomposition of the covariance function as the sum of periodic and aperiodic kernels. This decomposition allows for the creation of sub-models which capture the periodic nature of the signal and its complement. To quantify the periodicity of the signal, we derive a periodicity ratio which reflects the uncertainty in the fitted sub-models. Although the method can be applied to many kernels, we give a special emphasis to the Matérn family, from the expression of the reproducing kernel Hilbert space inner product to the implementation of the associated periodic kernels in a Gaussian process toolkit. The proposed method is illustrated by considering the detection of periodically expressed genes in the arabidopsis genome.

Periodic-cylinder vesicle with minimal energy

We give some details about the periodic cylindrical solution found by Zhang and Ou-Yang in [1996 Phys. Rev. E 53 4206] for the general shape equation of vesicle. Three different kinds of periodic cylindrical surfaces and a special closed cylindrical surface are obtained. Using the elliptic functions contained in mathematic, we find that this periodic shape has the minimal total energy for one period when the period–amplitude ratio β ≈ 1.477, and point out that it is a discontinuous deformation between plane and this periodic shape. Our results also are suitable for DNA and multi-walled carbon nanotubes (MWNTs). (cross-disciplinary physics and related areas of science and technology)

Unstable periodic orbits and chaotic economic growth

We numerically find many unstable periodic solutions embedded in a chaotic attractor in a macroeconomic growth cycle model of two countries with different fiscal policies, and we focus on a special type of the unstable periodic solutions. It is confirmed that chaotic behavior represented by the model is qualitatively and quantitatively related to the unstable periodic solutions. We point out that the structure of a chaotic solution is dissolved into a class of finite unstable periodic solutions picked out among a large number of periodic solutions. In this context it is essential for the unstable periodic solutions to be embedded in the chaotic attractor

Bound states in the continuum on periodic structures surrounded by strong resonances

Science.gov (United States)

Yuan, Lijun; Lu, Ya Yan

2018-04-01

Bound states in the continuum (BICs) are trapped or guided modes with their frequencies in the frequency intervals of the radiation modes. On periodic structures, a BIC is surrounded by a family of resonant modes with their quality factors approaching infinity. Typically the quality factors are proportional to 1 /|β - β*|2 , where β and β* are the Bloch wave vectors of the resonant modes and the BIC, respectively. But for some special BICs, the quality factors are proportional to 1 /|β - β*|4 . In this paper, a general condition is derived for such special BICs on two-dimensional periodic structures. As a numerical example, we use the general condition to calculate special BICs, which are antisymmetric standing waves, on a periodic array of circular cylinders, and show their dependence on parameters. The special BICs are important for practical applications, because they produce resonances with large quality factors for a very large range of β .

Bi-periodicity evoked by periodic external inputs in delayed Cohen-Grossberg-type bidirectional associative memory networks

In this paper, the bi-periodicity issue is discussed for Cohen-Grossberg-type (CG-type) bidirectional associative memory (BAM) neural networks (NNs) with time-varying delays and standard activation functions. It is shown that the model considered in this paper has two periodic orbits located in saturation regions and they are locally exponentially stable. Meanwhile, some conditions are derived to ensure that, in any designated region, the model has a locally exponentially stable or globally exponentially attractive periodic orbit located in it. As a special case of bi-periodicity, some results are also presented for the system with constant external inputs. Finally, four examples are given to illustrate the effectiveness of the obtained results.

In a previous paper, we proposed another special critical value concerning the evolution of the long period family around the equilateral equilibrium points, besides the two values given by Henrard. Are there any other special critical values? After studying the stability curves of the long period family carefully, we gave a negative answer. During the study, we found an interesting family of periodic orbits which we called the homo family. We studied the evolution of this family following the increase of μ. With these findings, we were able to explain the origin of the four branches of periodic families emanating from L 4 and the stability results of the equilateral equilibrium points.

Metabolic Disorders in the Transition Period Indicate that the Dairy Cows' Ability to Adapt is Overstressed.

Science.gov (United States)

Sundrum, Albert

2015-10-09

Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand. Adaptation is a functional and target-oriented process involving the whole organism and thus cannot be narrowed down to single factors. Most problems which challenge the organisms can be solved in a number of different ways. To understand the mechanisms of adaptation, the interconnectedness of variables and the nutrient flow within a metabolic network need to be considered. Metabolic disorders indicate an overstressed ability to balance input, partitioning and output variables. Dairy cows will more easily succeed in adapting and in avoiding dysfunctional processes in the transition period when the gap between nutrient and energy demands and their supply is restricted. Dairy farms vary widely in relation to the living conditions of the animals. The complexity of nutritional and metabolic processes Animals 2015, 5 979 and their large variations on various scales contradict any attempts to predict the outcome of animals' adaptation in a farm specific situation. Any attempts to reduce the prevalence of metabolic disorders and associated production diseases should rely on continuous and comprehensive monitoring with appropriate indicators on the farm level. Furthermore, low levels of disorders and diseases should be seen as a further significant goal which carries weight in addition to productivity goals. In the long run, low disease levels can only be expected when farmers realize that they can gain a competitive advantage over competitors with higher levels of disease.

This is the national report for Norway in phase 5 of the SAVE project 'Cross country comparison of energy efficiency indicators'. The report deals with energy use and energy efficiency in Norway the last 20 years, with a special emphasis on the period after 1990. A detailed sector analysis has been done, applying Laspeyres indices to attribute changes in energy use to either activity, structure or intensity (efficiency). Aggregating sectors, we have found a total efficiency improvement of maximum 7-8 TWH from 1990 to 1997. This corresponds to a saving of 0.5% per year. In the same period, final energy use per Gross Domestic Product (GDP) was reduced by approx 2.4% per year. Thereby most of the reduction in final energy intensity can not be attributed to increased energy efficiency. Almost all data are taken from official Norwegian statistics (Statistics Norway).

Changes in the precipitation regimes are expected to be accompanied by variations in the occurrence of extreme events, which in turn could be related to low frequency variability. The impact on the society and environment requires that the regional specificities are understood. For mainland Portugal, this work reports the results of the analysis of trends in selected precipitation indices calculated from daily precipitation data from 57 meteorological stations, recorded in the period 1941-2007; additionally we have also investigated the correlations between these indices and several modes of low frequency variability over the area. We focus on exploring regional differences and seasonal variations in the intensity, frequency and duration of extreme precipitation events. The precipitation indices were assessed at the seasonal scale and calculated at both the station and regional scales. Results sometimes highlight marked changes in seasonal precipitation and show that: i) trends in spring and autumn have opposite signals: statistically significant drying trends in the spring are accompanied by a reduction in precipitation extremes; in autumn, wetting trends are detected for all precipitation indices, although overall they are not significant at the 5% level; ii) there seems to be a tendency for a reduction in the duration of the rainy season; iii) the North Atlantic Oscillation (NAO) is the mode of variability that has the highest influence on precipitation extremes over mainland Portugal, particularly in the winter and autumn, and is one of the most important teleconnection patterns in all seasons. This work was partially supported by FEDER (Fundo Europeu de Desenvolvimento Regional) funds through the COMPETE (Programa Operacional Factores de Competitividade) and by national funds through FCT (Fundação para a Ciência e a Tecnologia, Portugal) through project STORMEx FCOMP-01-0124-FEDER-019524 (PTDC/AAC-CLI/121339/2010).

Full Text Available Background and Purpose: Forests monitoring is one of the largest forest bio-monitoring systems that is carried out in order to record changes by using the most important environmental parameters. The National Focal Centre for forest monitoring in the Republic of Serbia, within the Institute of Forestry of the Republic of Serbia has been taking an active part in an international program of ICP Forest, with a view to improving its working activities and harmonizing them with other approaches to monitoring forests and forest ecosystems. Material and Methods: In order to determine forest ecosystem processes, it is necessary to carry out detailed research of ecological and socio-economic consequences of forest deterioration and to study the impacts of regional climate changes on forest communities. In the period from 2004 to 2009, observations were performed on 130 sample plots and data necessary for further analysis were collected. These plots are systematically arranged in either a 16x16 km or a 4 x 4 km grid system. The main parameters assessed on the sample plots are the degree of defoliation and discolouration as well as the extent of damage. A comparative analysis of the data obtained in this period will provide a better insight into the present state of beech forests in Serbia as well the effects of defoliation and discolouration trends. Results and Conclusion: Beech is the most common broadleaved tree species on the Level I sample plots. Its health state is the result of adverse effects of complex factors of abiotic and biotic origin (i.e. effects of both living organisms and complex natural processes within the beech forests habitats. This paper presents some indicators of beech forest vitality whose occurrence show certain regularity and which can be interpreted as a trend. The annual values of the health state elements and the fluctuations of these parameters from year to year present important indicators of vitality of beech forests in

Full Text Available Language disciplines, including Terminology and Specialized Translation, have made great strides after the second half of the twentieth century. This development, related to technological growth and international communication that occurred during this period, has resulted in a considerable increase of concepts. Thus, experts have become more and more aware of the importance of naming these new concepts. Specialized translators were among the first language professionals to recognize the need of mastering the terminology of specialized fields in order to perform their duties well (Antia et coll., 2005. In this work, we study the very close relationship between Terminology and Specialized Translation. We also study the theoretical and practical knowledge of Terminology that a specialized translator should have.

Metabolic Disorders in the Transition Period Indicate that the Dairy Cows’ Ability to Adapt is Overstressed

Directory of Open Access Journals (Sweden)

Albert Sundrum

2015-10-01

Full Text Available Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand. Adaptation is a functional and target-oriented process involving the whole organism and thus cannot be narrowed down to single factors. Most problems which challenge the organisms can be solved in a number of different ways. To understand the mechanisms of adaptation, the interconnectedness of variables and the nutrient flow within a metabolic network need to be considered. Metabolic disorders indicate an overstressed ability to balance input, partitioning and output variables. Dairy cows will more easily succeed in adapting and in avoiding dysfunctional processes in the transition period when the gap between nutrient and energy demands and their supply is restricted. Dairy farms vary widely in relation to the living conditions of the animals. The complexity of nutritional and metabolic processes Animals 2015, 5 979 and their large variations on various scales contradict any attempts to predict the outcome of animals’ adaptation in a farm specific situation. Any attempts to reduce the prevalence of metabolic disorders and associated production diseases should rely on continuous and comprehensive monitoring with appropriate indicators on the farm level. Furthermore, low levels of disorders and diseases should be seen as a further significant goal which carries weight in addition to productivity goals. In the long run, low disease levels can only be expected when farmers realize that they can gain a competitive advantage over competitors with higher levels of disease.

The research shows that the period of 1980 - 2000 in Yogyakarta Special Province has indicated very significantly the increase in population, the development of road and the extension of built up area. For the time being, agricultural land mainly in Sleman Regency, Bantul Regency and Yogyakarta Municipality has decreased. Sleman regency performed the largest decrease of rice field and followed after then by Bantul regency and Yogyakarta Municipality. The regency of Kulon Progo and Gunung Kidul have experienced reverse phenomenon i.e. the increase of rice field during this period. Individually or simultaneously, three variables used in this research (number of people, road's length and built up area have significantly influenced the agricultural land use.

Beam-wave interaction in periodic and quasi-periodic structures. 2. ed.

International Nuclear Information System (INIS)

Schaechter, Levi

2011-01-01

The main theme of this book is the interaction of electrons with electromagnetic waves in the presence of periodic and quasi-periodic structures in vacuum, in view of applications in the design and operation of particle accelerators. The first part of the book is concerned with the textbook-like presentation of the basic material, in particular reviewing elementary electromagnetic phenomena and electron dynamics. The second part of the book describes the current models for beam-wave interactions with periodic and quasi-periodic structures. This is the basis for introducing, in the last part of the book, a number of particle and radiation sources that rest on these principles, in particular the free-electron laser, wake-field acceleration schemes and a number of other advanced particle accelerator concepts. This second edition brings this fundamental text up-to-date in view of the enormous advances that have been made over the last decade since the first edition was published. All chapters, as well as the bibliography, have been significantly revised and extended, and the number of end-of-chapter exercises has been further increased to enhance this book's usefulness for teaching specialized graduate courses.

Knowledge Enclosures, Forced Specializations and Investment Crisis

Directory of Open Access Journals (Sweden)

Filippo Belloc

2012-12-01

Full Text Available Like land before the industrial revolution, in the present global economy much knowledge is being enclosed in private hands. In this paper we argue that these enclosures have become a major factor in specialization among firms and among countries: both are forced to specialize in the fields that are not restricted by the enclosures of the others. We use data on 26 OECD countries over the 1978-2006 period. We estimate the effect of patents endowments of countries on their investment specialization across sectors and show that knowledge enclosures involve self-reinforcing innovation patterns. Moreover, we perform a structural change analysis and find that the TRIPs agreement has significantly strengthened the relationship between countries' patents specialization and investment specialization. We conclude by suggesting that stronger international patent protection may restrict global investment opportunities, and this may be one of the factors contributing to the present crisis.

Metabolic Disorders in the Transition Period Indicate that the Dairy Cows’ Ability to Adapt is Overstressed

Sundrum, Albert

2015-01-01

Simple Summary Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. Problems derive from difficulties animals have to adapt to large variations and disturbances occurring both outside and inside the organism. A lack of success in solving these issues may be due to predominant approaches in farm management and agricultural science, dealing with such disorders as merely negative side effects. Instead, a successful adaptation of animals to their living conditions should be seen as an important end in itself. Both farm management and agricultural sciences should support animals in their ability to cope with nutritional and metabolic challenges by employing a functional and result-driven approach. Abstract Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand.

To identify current trends of root canal treatment for patients with special needs. A postal questionnaire was sent to General Dentists in Victoria, Australia and Endodontists and Special Needs Dentists across Australia to determine the extent of root canal treatment performed on special needs patients. Over a four-month period, 1120 questionnaires were distributed with an overall response rate of 63.9% (n = 716). Response rates were 63.2% (n = 655), 68.5% (n = 50) and 100.0% (n = 11) amongst General Dentists, Endodontists and Special Needs Dentists, respectively. Endodontists (95.7%) and Special Needs Dentists (100.0%) performed significantly more root canal treatment on adult patients with special needs compared with 51.2% of General Dentists, (P special needs patients compared with only 29.7% of General Dentists (P special needs patients was more likely to be carried out by specialist dental practitioners who were more likely to utilize a pharmacological approach for behaviour guidance and to perform single-visit root canal treatment compared with General Dentists.

Existence and global attractivity of positive periodic solutions of periodic n-species Lotka-Volterra competition systems with several deviating arguments.

Science.gov (United States)

Fan, M; Wang, K; Jiang, D

1999-08-01

In this paper, we study the existence and global attractivity of positive periodic solutions of periodic n-species Lotka-Volterra competition systems. By using the method of coincidence degree and Lyapunov functional, a set of easily verifiable sufficient conditions are derived for the existence of at least one strictly positive (componentwise) periodic solution of periodic n-species Lotka-Volterra competition systems with several deviating arguments and the existence of a unique globally asymptotically stable periodic solution with strictly positive components of periodic n-species Lotka-Volterra competition system with several delays. Some new results are obtained. As an application, we also examine some special cases of the system we considered, which have been studied extensively in the literature. Some known results are improved and generalized.

Mind the gap: gender differences in child special health care needs.

Science.gov (United States)

Leiter, Valerie; Rieker, Patricia P

2012-07-01

The gendered nature of special health care needs in childhood is an important yet understudied area. Although gendered differences in the prevalence of special health care needs have been documented, there is less knowledge about the factors which contribute to those differences. Two research questions guide this inquiry. First, is the gender gap consistent across child special health care need indicators? Second, to what extent is the gender gap in special health care needs driven by behavioral conditions? We use multiple indicators from the U.S. National Survey of Children's Health to expand our understanding about the dynamic relationship between gender and childhood health. There are clear gender differences in the prevalence of special health care needs. Boys are more likely than girls to have special health care needs overall and on the five separate components examined (medication, more care than typical, limitations, special therapies, and educational or behavioral problem). This gender gap is dynamic and varies by indicator; while behavioral conditions play a role, it remains even after controlling for behavioral conditions. The reasons for the gender differences appear to be both biological and social but much remains unknown about this pattern.

Tamper indicating radiation surveillance instrumentation

International Nuclear Information System (INIS)

Chambers, W.H.; Ney, J.F.

1975-01-01

Prototype personnel and shipping dock portal monitors suitable for unattended use were fabricated and tested. The requirement for continuous operation with only periodic inspection along with a desire for minimum costs and minimum interference with normal plant operation imposed unique design constraints. The design, operation, and performance of the detection and data recording instrumentation are described, as well as the tamper indicating techniques required to protect the collected data. The essential elements of either of the two instruments include a gamma detector array, signal conditioning electronics, digital alarm logic circuitry, power supplies, a microwave occupancy monitor, surveillance camera, irreversible electromechanical counters, and the appropriate tamper indicating envelope protecting these elements. Attempts to penetrate the tamper indicating envelope require material removal, and undetectable repair is very difficult, if not impossible. The techniques for joining major subassemblies and providing unique seals are also described. The personnel doorway uses a double pole array of NaI(Tl) detectors, and outputs are taken from a single channel pulse height analyzer with a window set at 60 to 250 keV and the lower level discriminator at greater than 60 keV. A sliding interval counter is used to make comparisons to an accumulated background at the 4sigma level. Logic design, sensitivity for special nuclear materials, false alarm data, and test procedures are described in detail. The shipping dock monitor had different design constraints and therefore uses a single, long, cylindrical plastic scintillator. Some differences in signal conditioning and processing are also described. (auth)

Design of membrane pressure indicators with strain gages

International Nuclear Information System (INIS)

Haberzettl, G.

1979-01-01

A special type of pressure indicators, more or less well known under the name of 'membrane pressure indicators' is dealt with. In principle, they consist of a pipe socket which is open at one end and sealed by the 'membrane' at the other end. In case of internal pressure from the open side, the membrane will begin to arch. This arch, which is proportional to the internal pressure, is measured by suitable methods. A special form of strain ganges, so-called 'membrane pressure roses' have turned out to be particularly suitable here. The article gives general guidelines for the construction of membrane pressure indicators. (orig./HT) [de

The need for and the importance of biological indicators of radiation effects with special reference to injuries in radiation accidents

International Nuclear Information System (INIS)

Koeteles, G.J.; Bianco, A.

1982-01-01

The need for further research on the existing and new biological indicators of radiation injury has been expressed. The studies on the radiation-induced alterations of membrane structure and function stimulated investigations aiming to develop an indicator based on membrane-phenomena. The co-ordinated research programme on ''Cell Membrane Probes as Biological Indicators of Radiation Injury in Radiation Accidents'' was initiated in mid 1977 and terminated in 1980. Within this programme many basic observations were made in connection with altered features of various animal and human cell membranes. Molecular, biophysical, biochemical and cell biological approaches were performed. The rapid reaction within minutes or hours of membranes against relatively low doses of various types of irradiations were described and the effects proved to be transitory, i.e. membrane regeneration occurred within hours. These dose- and timedependent alterations suggest the possibility of developing a biological indicator which would give signals at the earliest period after radiation injury when no other biological informations are available. The importance of a system of biological indicators is emphasized. (author)

Lifshitz singularities in random harmonic chains: periodic amplitudes near the band edge and near special frequencies

International Nuclear Information System (INIS)

Nieuwenhuizen, T.M.; Luck, J.M.

1987-01-01

The authors give a complete description of the scaling behavior of the integrated density of states of random harmonic chains with random masses near the band edge omega/sub max/ and near special frequencies omega/sub s/. There are four different situations: omega upward arrow omega/sub max/, omega upward arrow omega/sub s/, omega upward arrow omega/sub s/ (critical case), omega upward arrow omega/sub s/ (general case). Their analytic results have the form of infinite sums involving Fourier coefficients of the scaling behavior of the Dyson-Schmidt function at the special frequency or the band edge. Binary mass distributions are considered in detail in the limit of a small fraction rho of light masses. Their predictions are compared with extensive numerical data

2011-08-01

Full Text Available In the research, at sample of 80 tested, employees in the special police force, as representatives of police population age from 20 to 25, diagnostics of motor potential in transitive period of annual macrostructure was done. The aim of the research was doing potential correction in planning and programming of transformation process in the next cycles of sports preparation on the base of diagnosed quantitative value of motor abilities. Besides analyses of achieved values, the difference was established between two leading teams in the space of measuring potential. The research results indicated to statistically important differences between two groups of tested people, as well as to unacceptable level of development in some abilities. The achieved results are, from aspect of training process’ control, the indicator to instructors’ team on the need of correction of transformation process’ content, with aim of improving bad segments. Diagnostics of motor abilities with measuring instruments in terrain conditions is one of methods, which can be in function of valorising transformation process of the special police force, taking into account specifics of their professional manifestation.

Time variations of geomagnetic activity indices Kp and Ap: an update

Directory of Open Access Journals (Sweden)

1997-10-01

Full Text Available Kp and Ap indices covering the period 1932 to 1995 are analysed in a fashion similar to that attempted by Bartels for the 1932–1961 epoch to examine the time variations in their characteristics. Modern analysis techniques on the extended data base are used for further insight. The relative frequencies of occurrence of Kp with different magnitudes and the seasonal and solar cycle dependences are seen to be remarkably consistent despite the addition of 35 years of observations. Many of the earlier features seen in the indices and special intervals are shown to be replicated in the present analysis. Time variations in the occurrence of prolonged periods of geomagnetic calm or of enhanced activity are presented and their relation to solar activity highlighted. It is shown that in the declining phase the occurrence frequencies of Kp = 4–5 (consecutively over 4 intervals can be used as a precursor for the maximum sunspot number to be expected in the next cycle. The semi-annual variation in geomagnetic activity is re-examined utilising not only the Ap index but also the occurrence frequencies of Kp index with different magnitudes. Lack of dependence of the amplitude of semi-annual variation on sunspot number is emphasised. Singular spectrum analysis of the mean monthly Ap index shows some distinct periodic components. The temporal evolution of ~44 month, ~21 month and ~16 month oscillations are examined and it is postulated that while QBO and the 16 month oscillations could be attributed to solar wind and IMF oscillations with analogous periodicity, the 44 month variation is associated with a similar periodicity in recurrent high speed stream caused by sector boundary passage. It is reconfirmed that there could have been only one epoch around 1940 when solar wind speed could have exhibited a 1.3-year periodicity comparable to that seen during the post-1986 period.

The emergence of medical specialization in the nineteenth century.

Science.gov (United States)

Weisz, George

2003-01-01

This essay reexamines the nineteenth-century origins of medical specialization. It suggests that by the 1880s, specialization had become perceived as a necessity of medical science as a result of the realization of two preconditions: First, a new collective desire to expand medical knowledge prompted clinical researchers to specialize; only specialization, it was believed, permitted the rigorous observation of many cases. Second, administrative rationality suggested that one could best manage large populations through proper classification, gathering together individuals belonging to the same class and separating those belonging to different categories. Both of these conditions emerged first and most powerfully in early nineteenth-century Paris. They were, in contrast, uniquely underdeveloped in the fragmented medical community of London during this period.

Special actinide nuclides: Fuel or waste?

International Nuclear Information System (INIS)

Srinivasan, M.; Rao, K.S.; Dingankar, M.V.

1989-01-01

The special actinide nuclides such as Np, Cm, etc. which are produced as byproducts during the operation of fission reactors are presently looked upon as 'nuclear waste' and are proposed to be disposed of as part of high level waste in deep geological repositories. The potential hazard posed to future generations over periods of thousands of years by these long lived nuclides has been a persistent source of concern to critics of nuclear power. However, the authors have recently shown that each and every one of the special actinide nuclides is a better nuclear fuel than the isotopes of plutonium. This finding suggests that one does not have to resort to exotic neutron sources for transmuting/incinerating them as proposed by some researchers. Recovery of the special actinide elements from the waste stream and recycling them back into conventional fission reactors would eliminate one of the stigmas attached to nuclear energy

Attitudes of Mexican anesthesiologists to indicate preoperative fasting periods: A cross-sectional survey

Directory of Open Access Journals (Sweden)

Nava-Ocampo Alejandro A

2002-05-01

Full Text Available Abstract Background In Mexico, guidelines for fasting periods, or any audits on this topic are unavailable, and therefore the attitudes of anesthesiologists for recommending preoperative fasting periods are unknown. Material and methods The study was a cross-sectional survey of anesthesiologists subscribed to the Annual Updated Course, organized by the Sociedad Mexicana de Anestesiologia in 2000. The response rate was 31.4%. Results Most respondents were general anesthesiologists, with 5 or more years experience in a clinical post, were working in both public and private hospitals, and were performing anesthetic procedures on both pediatric and adult patients and in both ambulatory and hospitalized patients. Approximately 23% of the respondents considered natural fruit juices to be clear liquids. For a pediatric patient ingesting breast milk 1 h before undergoing a surgical procedure, 45% thought that surgery should be delayed for 3h, followed by those delaying the surgical procedure for 6 to 8 h. Our results show that more than 50% of the anesthesiologists had better defined attitudes for fasting milk and clear liquids in patients of 6 month or under than for older children and adults. However, due to the poor definition or pre-operative fasting, using clear liquids, in all other patient groups, several patients are allowed to go without oral clear liquids administration for prolonged periods. Conclusion Preoperative fasting periods recommended by Mexican anesthesiologists differ from international guidelines.

This article gives an evidence-based overview about several special indications for scintigraphy in imaging infection and inflammation. In diagnosing and evaluating the extent of inflammatory bowel disease, the scintigraphy with {sup 99m}Tc-HMPAO labelled leucocytes remains the standard evaluation in Nuclear Medicine. Appendicitis can be proven or excluded with a high grade of certainty both by {sup 99m}Tc-labelled monoclonal antigranulocytic antibodies and FAb'-fragments and by in-vitro labelled leucocytes. In endocarditis a late SPECT (20-24 h p. i.) with a {sup 99m}Tc-labeled anti-CD66 monoclonal antibody is a useful adjunct to echocardiographic techniques. In infected vascular prostheses, {sup 99m}Tc-HMPAO-labelled autologous leucocytes remain the standard of Nuclear Medicine although [{sup 18}F]FDG-PET or [{sup 18}F]FDG-PET / CT may exhibit a higher diagnostic accuracy.

Agrarian foreign trade of the Czech Republic in the period of 2004–2008, competitiveness of commodities

Directory of Open Access Journals (Sweden)

Jaroslava Burianová

2011-01-01

Full Text Available The paper deals with agrarian foreign trade (AFT of the Czech Republic during the period of 2004–2008. Distinct changes in the trade volume, but also changes in the net export structure were observed. The export is being assisted with a much larger trading area without customs restrictions but it is also exposed to a much tougher competition. A methodology that makes it possible to evaluate the competitiveness of individual commodities is described in the first part. A sequence of individual items from a total list of basic food goods was analyzed using chosen indicators – Balass indicator RCA (Revealed Comparative Advantage as well as the Michaely index MI that shows a specific degree of specialization for export. In the Results section, attention is firstly focused on the year 2004. The values of export and import for 24 items of basic food commodities are summarised, and the most important items in respect of the share in total export are selected. Analogical output was acquired for the year 2008. The values of RCA and MI indicators are then itemised, and a sequence is determined for the highest values for the commodities able to compete that shows the specific degree of specialization for export.

Stability of elastic columns with periodic retarded follower forces

Science.gov (United States)

Ma, Haitao; Butcher, Eric A.

2005-09-01

The objective of this work is to present a stability analysis for elastic columns under the influence of periodically varying follower forces whose orientation is retarded, i.e., depends on the position of the system at a previous time. One- and two-degree-of-freedom (dof) discretized systems under the simultaneous influence of both parametric excitation and time-delay, whose effects on such systems have previously been only considered separately, are studied. By employing an orthogonal polynomial approximation, the infinite-dimensional Floquet transition matrix associated with the time-periodic differential-delay system is approximated. The stability criteria that all the eigenvalues (Floquet multipliers) of this matrix must lie within the unit circle is then applied. The stability charts for different combinations of the remaining system parameters are shown, and the previously reported results for the special cases where either the parametric excitation or the time-delay vanishes are verified. Two cases, when the parametric forcing period is equal to or twice the delay period are taken into consideration in this work. For special cases of the single dof system, the numerical stability plots are verified by considering the analytical expressions for the corresponding stability boundaries for an analogous delayed Mathieu equation.

The generalized algebraic method with symbolic computation is extended to some special-type nonlinear equations for constructing a series of new and more general travelling wave solutions in terms of special functions. Such equations cannot be directly dealt with by the method and require some kinds of pre-processing techniques. It is shown that soliton solutions and triangular periodic solutions can be established as the limits of the Jacobi doubly periodic wave solutions.

Physical explanation of the periodic table.

Science.gov (United States)

Ostrovsky, V N

2003-05-01

The Periodic Table of the elements, the most important generalization in chemistry, is often considered as a representative special case in the study of the relation between chemistry and physics. Its quantum interpretation was initiated, but not completed, by Niels Bohr. In this paper, post-Bohr conceptual developments are discussed from historical and epistemological points of view. The difference between high-precision numerical calculations for individual atoms and the theory of the periodic system as a whole is emphasized. Periodic laws met in Nature are not restricted to the chemical Periodic Table. A comparative study of these laws makes it possible to single out essential features that define the particular pattern of periodicity. It is shown that the periodic system of neutral ground state atoms now has a firm nonempirical quantum-theoretical basis. Alternative approaches, based on group theory and other mathematical schemes, are briefly discussed. It is argued that, while quantum theory is capable of fully accurate calculations for relatively simple atoms or molecular objects, the complexity of polyatomic molecules and chemical reactions guarantees the flourishing of chemistry as a separate scientific discipline.

Concurrent hypokalemic periodic paralysis and bipolar disorder

Directory of Open Access Journals (Sweden)

Chia-Lin Lin

2015-01-01

Full Text Available Primary periodic paralysis is a rare autosomal dominant disorder of ion-channel dysfunction, manifested by episodic flaccid paresis secondary to abnormal sarcolemma excitability. Membrane destabilization involving Na, K-ATPase has been hypothesized to be a biological etiology of the bipolar disorder (BD and the mechanisms underlying lithium therapy have been linked to it. To date, there has been only one reported case of BD comorbid with periodic paralysis. Herein, we reported another case of concurrent bipolar mania and hypokalemic periodic paralysis (HPP, one special form of periodic paralysis. Consistent with the previous case, our patient responded well to lithium treatment for both bipolar mania and HPP. This might provide some support to the hypothesis that the therapeutic effects of lithium in both BD and HPP could be due to the correction of the underlying common pathophysiology.

The "sticking period" in a maximum bench press.

Science.gov (United States)

van den Tillaar, Roland; Ettema, Gertjan

2010-03-01

The purpose of this study was to examine muscle activity and three-dimensional kinematics in the ascending phase of a successful one-repetition maximum attempt in bench press for 12 recreational weight-training athletes, with special attention to the sticking period. The sticking period was defined as the first period of deceleration of the upward movement (i.e. from the highest barbell velocity until the first local lowest barbell velocity). All participants showed a sticking period during the upward movement that started about 0.2 s after the initial upward movement, and lasted about 0.9 s. Electromyography revealed that the muscle activity of the prime movers changed significantly from the pre-sticking to the sticking and post-sticking periods. A possible mechanism for the existence of the sticking period is the diminishing potentiation of the contractile elements during the upward movement together with the limited activity of the pectoral and deltoid muscles during this period.

Individual and hospital-specific factors influencing medical graduates' time to medical specialization.

Previous studies of gender differences in relation to medical specialization have focused more on social variables than hospital-specific factors. In a multivariate analysis with extended Cox regression, we used register data for socio-demographic variables (gender, family and having a child born during the study period) together with hospital-specific variables (the amount of supervision available, efficiency pressure and the type of teaching hospital) to study the concurrent effect of these variables on specialty qualification among all 2474 Norwegian residents who began specialization in 1999-2001. We followed the residents until 2010. A lower proportion of women qualified for a specialty in the study period (67.9% compared with 78.7% of men, p specialization qualification (p specialization: working at university hospitals (regional) or central hospitals was associated with a reduction in the time taken to complete the specialization, whereas an increased patient load and less supervision had the opposite effect. Multivariate analysis showed that the smaller proportion of women who qualified for a specialty was explained principally by childbirth and by the number of children aged under 18 years.

Smart Specialization Strategy and its Operationalization in the Regional Policy: Case Finland

Directory of Open Access Journals (Sweden)

Jari Kaivo-oja

2017-06-01

Full Text Available In the European Union, smart specialization is an important concept in regional policy. Its primary aim is to achieve inclusive and sustainable economic growth. There is a lack of convenient region specific measures to operationalize smart specialization startegies (S3. The purpose of the paper is to find “indices of smart specialization” on a regional level. We propose indices that are based on (1 the rate of industrial diversification, (2 revealed comparative advantage and (3 regions’ overall relative specialization. In the empirical part, we analyze smart specialization in Finland using structural data provided by Statistics Finland for seventy sub-regions (LAU1 and 24 sub-industries in manufacturing. These industries are the most important for exports, productivity, and regional economic performance for a small country. The following indices are used in empirical evaluations: Herfindahl-Hirschman Index (HHI for regional diversity, Balassa-Hoover Index (BHI for revealed comparative advantage, and Region’s Relative Specialization Index (RRSI for aggregate regional specialization differences. The concept of smart specialization is related to these measures. Index analyses reveal that many growing sub-regions have similar comparative advantages. This means inter-regional synergy, and it enables opportunities for strategic cooperation between regions. To develop smart specialization strategies for Europe’s regions, we need these kinds of empirical knowledge-based management tools and planning approaches.

Pulsation properties of Mira long period variables

Cahn, J.H.

1980-01-01

A matter of great interest to variable star students concerns the mode of pulsation of Mira long period variables. In this report we first give observational evidence for the pulsation constant Q. We then compare the observations with calculations. Next, we review two interesting groups of papers dealing with hydrodynamic properties of long period variables. In the first, a fully dynamic nonlinear calculation maps out the Mira instability domain. In the second, special attention is paid to shock propagation beyond the photosphere which in large measure accounts for the complex spectra from this region. (orig./WL)

A random walk description of individual animal movement accounting for periods of rest

Science.gov (United States)

Tilles, Paulo F. C.; Petrovskii, Sergei V.; Natti, Paulo L.

2016-11-01

Animals do not move all the time but alternate the period of actual movement (foraging) with periods of rest (e.g. eating or sleeping). Although the existence of rest times is widely acknowledged in the literature and has even become a focus of increased attention recently, the theoretical approaches to describe animal movement by calculating the dispersal kernel and/or the mean squared displacement (MSD) rarely take rests into account. In this study, we aim to bridge this gap. We consider a composite stochastic process where the periods of active dispersal or `bouts' (described by a certain baseline probability density function (pdf) of animal dispersal) alternate with periods of immobility. For this process, we derive a general equation that determines the pdf of this composite movement. The equation is analysed in detail in two special but important cases such as the standard Brownian motion described by a Gaussian kernel and the Levy flight described by a Cauchy distribution. For the Brownian motion, we show that in the large-time asymptotics the effect of rests results in a rescaling of the diffusion coefficient. The movement occurs as a subdiffusive transition between the two diffusive asymptotics. Interestingly, the Levy flight case shows similar properties, which indicates a certain universality of our findings.

Energy efficiency in Norway (1996). Cross Country Comparison on Energy Efficiency Indicators, Phase 4

Energy Technology Data Exchange (ETDEWEB)

Alm, Leif Kristian

1998-12-01

This is the national report for Norway in phase 4 of the SAVE project 'Cross country comparison of energy efficiency indicators'. The report deals with energy use and energy efficiency in Norway the last 20 years, with a special emphasis on the period after 1990. Final energy use per Gross Domestic Product (GDP) was reduced by approx 2.3% per year from 1990 to 1996. Doing detailed sector analysis we are applying Laspeyres indices to attribute changes in energy use to either activity, structure or intensity. Calculating an aggregate intensity index from the sector intensities gives an average intensity reduction of 0.4% per year. Thereby most of the reduction in final energy per unit GDP are due to structural changes, and not technical improvements. Almost all data are taken from official Norwegian statistics (Statistics Norway). (author)

The Evolution of the Population of the City of Zagreb with Special Emphasis on Immigration in the Period 1991−2001

Directory of Open Access Journals (Sweden)

Nada Antić

2001-12-01

Full Text Available The paper describes the evolution of Zagreb's population and its geographical distribution in the city during the last ten years. Emphasis is placed on the role of migration (involving essentially the settling in of new inhabitants and on the influence of the armed conflict in the 1990s. The author also outlines some predictions regarding future developments. The paper uses primarily the results of the last censuses, including those of the recent census of 2001, as well as statistical data on the current population, on displaced persons and refugees, information in the possession of the municipality, etc. As to migration, since the last census was lacking in regard to migration indicators and there is no population registry, vital-statistical methods were applied to obtain a net migration balance. In the past, especially after WWII, Zagreb experienced considerable demographical growth, owing to its attractiveness for migration flows from other regions in Croatia and in neighbouring Bosnia and Herzegovina. The natural component in the evolution of the population was equally positive, yet a tendency towards reduction appeared in the 1980s. The first part of the paper reviews the demographic expansion of Zagreb in the earlier period (1857−1991, which was accompanied by an extension of the city. The results of the last census (2001 indicate a notable slowing down of population growth in Zagreb (arriving at a growth rate of 0.39%, for although war-induced migrations in the period 1991−1995 did direct the majority of the refugees and displaced persons to Zagreb, this flow was not accompanied by permanent settlement. Most migrants originated from Bosnia and Herzegovina (mainly refugees, after which followed migrants from regions in Croatia. Studies also show that during the most recent period there was a clear increase of out-migration from Zagreb to the outer suburbs and of emigration abroad. The second part of the paper offers indicators on the

Time analysis in astronomy: Tools for periodicity searches

The authors discuss periodicity searches in radio and gamma-ray astronomy with special considerations for pulsar searches. The basic methodologies of fast Fourier transform, Rayleigh test, and epoch folding are reviewed with the main objective to compare cost and sensitivities in different applications. It is found that FFT procedures are convenient in unbiased searches for periodicity in radio astronomy, while in spark chamber gamma-ray astronomy, where the measurements are spread over a long integration time, unbiased searches are very difficult with the existing computing facilities and analyses with a-priori knowledge on the period values to look for are better done using the Rayleigh test with harmonics folding (Z /sub n/ test)

Pelvic region pressure sores often develop following spinal cord injury. Surgery is often necessary for long standing, large-sized pressure sores not responding to conservative treatment. Authors analyze their results of a 10-year period, and identify factors contributing to the reduction of the recurrence rate. A total of 119 pressure sores were operated on 98 patients in two institutions during a 10-year period (1 January 2003 to 31 December 2012). The encountered perioperative complications are summarized, and the recurrence rate is analyzed with a patient follow-up questionnaire. We experienced 15 perioperative complications (12.6%). All complications were fully resolved by conservative treatment. Fifty-eight returned patient replies were processed. The average follow-up time after surgery was 5.2 years. The recurrence rate was 5.47%. The strict adherence to surgical indications, full patient compliance, specialized pre- and post-operative patient care, our routinely used preferred surgical method, all contribute to a low post-operative complication rate, long-term flap survival, and an extended recurrence free period.

Full Text Available The indicators, precisely describing the linkages between tourism and the environment, social and cultural base, are not easily available. How ever, some relevant organizations (WTO, EU, OECD, etc., institutions and experts, have been hardly working to create the indicators of sustainable tourism. Whereas the economic objectives are easily defined by the use of the traditional indicators used in national and business economics, it is very difficult to identify widely applicable environmental, social and cultural indicators. In order to stimulate and alleviate the process of sustainable tourism development, EU created the list of comparative indicators of sustainable tourism. In preparing this list, special attention is paid to identification of valid indicators of real tourism impacts on the social and cultural environment (the entire set of traditions, customs, history, hospitality and culture that characterize a given area, that is a very complex task. Assuming the fact that the related indicators have been analyzed in many European countries, this paper is focused on applying the related indicators in research of tourism development in villages of the Kosjerić community. .

Mitzi Lauderdale

2012-06-01

Full Text Available This study examines factors associated with the likelihood of having a plan that includes a special needs trust among families that have disabled minor children. Descriptive analyses indicate that the top two reasons families provide for not having a plan are the inability to save and no perceived need. Among families that do indicate having a plan, most do not include a special needs trust. Multivariate analyses reveal that professional involvement (financial, legal, and mental health professionals is a key factor to increasing the likelihood of having a plan with a special needs trust. Families that have met with a financial advisor are 23 times more likely, and families who are encouraged to create a plan by a mental health professional are almost three times more likely, to have a plan that includes a special needs trust. Results from this study suggest that financial therapists are uniquely positioned to educate and ensure that appropriate plans are in place to provide for the future of children with special needs.

Full Text Available Purpose The present study aims to investigate the relationship between auditor tenure and stock return volatility and to study the moderating effect of auditor’s industry specialization on this relationship in the firms listed on the Tehran Stock Exchange (TSE. Design/methodology/approach A sample of 95 companies listed on the Tehran Stock Exchange during the period 2011 to 2015 was selected and two hypotheses were formulated and analyzed using multivariate regression and econometric models. Findings The results of the study indicate that with the increase of auditor tenure, the volatility of stock returns is reduced. However, the results showed that the use of auditors specializing in the client's industry does not affect the relationship between the length of auditor tenure and the volatility of stock returns. Originality/value The findings of current study not only extend the extant theoretical literature concerning the stock price volatility in developing countries including emerging capital market of Iran, but also help investors, capital market and audit profession regulators to make informed decisions.

On the periodicity in the distribution of quasar redshifts

International Nuclear Information System (INIS)

Kjaergaard, P.

1978-01-01

The periodicity in the distribution of quasar redshifts is explained in terms of selection effects. Special attention is drawn to a selection effect caused by the redshift dependent influence of the strong emission lines on the limiting magnitude for detecting quasars. This is especially important since the number of quasars increases with a large factor per magnitude. The limiting magnitude effect applies both to spectroscopic and to UV-excess surveys. It is shown that the redshift distribution of quasars selected by a combination of UV-excess information and agreement between radio and optical position is intermediate between the redshift distribution of the two groups of quasars selected by one of the two criteria. It is also shown that the distribution of redshifts for UV-excess selected quasars is very similar to the variation of the ultrsviolet excess as a function of redshift. This evidence indicates that strong selection effects are in play. (Auth.)

A technique to detect periodic and non-periodic ultra-rapid flux time variations with standard radio-astronomical data

Science.gov (United States)

Borra, Ermanno F.; Romney, Jonathan D.; Trottier, Eric

2018-06-01

We demonstrate that extremely rapid and weak periodic and non-periodic signals can easily be detected by using the autocorrelation of intensity as a function of time. We use standard radio-astronomical observations that have artificial periodic and non-periodic signals generated by the electronics of terrestrial origin. The autocorrelation detects weak signals that have small amplitudes because it averages over long integration times. Another advantage is that it allows a direct visualization of the shape of the signals, while it is difficult to see the shape with a Fourier transform. Although Fourier transforms can also detect periodic signals, a novelty of this work is that we demonstrate another major advantage of the autocorrelation, that it can detect non-periodic signals while the Fourier transform cannot. Another major novelty of our work is that we use electric fields taken in a standard format with standard instrumentation at a radio observatory and therefore no specialized instrumentation is needed. Because the electric fields are sampled every 15.625 ns, they therefore allow detection of very rapid time variations. Notwithstanding the long integration times, the autocorrelation detects very rapid intensity variations as a function of time. The autocorrelation could also detect messages from Extraterrestrial Intelligence as non-periodic signals.

Changes in Quantitative Indicators of Concentration in the Countries of this Region during the Transformation Period of Banking Systems

Roman Šubić

2010-07-01

Full Text Available The reshaping processes of the banking systems in the countries of this region that involved the reorganization and restructuring of insolvent banks as well as the privatization of the state banks were aimed at setting up a framework within which banks would operate according to the modern market principles. With the opening of the banking market to foreign capital, the foreign banks have gained access to the banking market and have over a ten-year period significantly increased their market share. Due to the existing barriers to entry into the market, foreign-owned banks tended to use the strategy of buying shares in already-established banks rather than starting up a new bank. Comparisons between concentration indicators showed that there are differences among countries and mostly these differences result from the differences in the size of the banking systems and the size of national economies. Still, the values of quantitative indicators of concentration in countries with larger banking systems are lower than in countries with fewer banks.

Dual Neutral Particle Beam Interrogation of Intermodal Shipping Containers for Special Nuclear Material

Science.gov (United States)

Keith, Rodney Lyman

Intermodal shipping containers entering the United States provide an avenue to smuggle unsecured or stolen special nuclear material (SNM). The only direct method fielded to indicate the presence of SNM is by passive photon/neutron radiation detection. Active interrogation using neutral particle beams to induce fission in SNM is a method under consideration. One by-product of fission is the creation of fragments that undergo radioactive decay over a time period on the order of tens of seconds after the initial event. The "delayed" gamma-rays emitted from these fragments over this period are considered a hallmark for the presence of SNM. A fundamental model is developed using homogenized cargos with a SNM target embedded at the center and computationally interrogated using simultaneous neutron and photon beams. Findings from analysis of the delayed gamma emissions from these experiments are intended to mitigate the effects of poor quality information about the composition and disposition of suspect cargo before examination in an active interrogation portal.

Educating Hungarian medical librarians in special literature.

Jantsits, G

1974-01-01

In Hungary the completion of a thirty-month course is required of those who wish to qualify as medium-level librarians. Medical librarians are given a special course which differs from the general course in that it covers the subjects of medical terminology and information in special literature. The latter subject is accorded the highest number of teaching hours, since the subject matter is vast and since, in addition to theory, much time must be spent on exercises and the presentation of reference books. The students become familiar with the main Hungarian and foreign information systems in the medical and related fields and with special bibliographies, encyclopedias, handbooks, and dictionaries. We take special care to familiarize students with the abstracting journals and indices. For several semesters they have homework and lesson exercises in the use of the Hungarian Medical Bibliography and Index Medicus.

Random-effects linear modeling and sample size tables for two special crossover designs of average bioequivalence studies: the four-period, two-sequence, two-formulation and six-period, three-sequence, three-formulation designs.

Due to concern and debate in the epilepsy medical community and to the current interest of the US Food and Drug Administration (FDA) in revising approaches to the approval of generic drugs, the FDA is currently supporting ongoing bioequivalence studies of antiepileptic drugs, the EQUIGEN studies. During the design of these crossover studies, the researchers could not find commercial or non-commercial statistical software that quickly allowed computation of sample sizes for their designs, particularly software implementing the FDA requirement of using random-effects linear models for the analyses of bioequivalence studies. This article presents tables for sample-size evaluations of average bioequivalence studies based on the two crossover designs used in the EQUIGEN studies: the four-period, two-sequence, two-formulation design, and the six-period, three-sequence, three-formulation design. Sample-size computations assume that random-effects linear models are used in bioequivalence analyses with crossover designs. Random-effects linear models have been traditionally viewed by many pharmacologists and clinical researchers as just mathematical devices to analyze repeated-measures data. In contrast, a modern view of these models attributes an important mathematical role in theoretical formulations in personalized medicine to them, because these models not only have parameters that represent average patients, but also have parameters that represent individual patients. Moreover, the notation and language of random-effects linear models have evolved over the years. Thus, another goal of this article is to provide a presentation of the statistical modeling of data from bioequivalence studies that highlights the modern view of these models, with special emphasis on power analyses and sample-size computations.

Zhang, J.; Becker-Reshef, I.; Justice, C. O.

2013-12-01

Although agricultural production has been rising in the past years, drought remains the primary cause of crop failure, leading to food price instability and threatening food security. The recent 'Global Food Crisis' in 2008, 2011 and 2012 has put drought and its impact on crop production at the forefront, highlighting the need for effective agricultural drought monitoring. Satellite observations have proven a practical, cost-effective and dynamic tool for drought monitoring. However, most satellite based methods are not specially developed for agriculture and their performances for agricultural drought monitoring still need further development. Wheat is the most widely grown crop in the world, and the recent droughts highlight the importance of drought monitoring in major wheat producing areas. As the largest wheat producing state in the US, Kansas plays an important role in both global and domestic wheat markets. Thus, the objective of this study is to investigate the capabilities of remotely sensed crop indicators for effective agricultural drought monitoring in Kansas wheat-grown regions using MODIS data and crop yield statistics. First, crop indicators such as NDVI, anomaly and cumulative metrics were calculated. Second, the varying impacts of agricultural drought at different stages were explored by examining the relationship between the derived indicators and yields. Also, the starting date of effective agricultural drought early detection and the key agricultural drought alert period were identified. Finally, the thresholds of these indicators for agricultural drought early warning were derived and the implications of these indicators for agricultural drought monitoring were discussed. The preliminary results indicate that drought shows significant impacts from the mid-growing-season (after Mid-April); NDVI anomaly shows effective drought early detection from Late-April, and Late-April to Early-June can be used as the key alert period for agricultural

Microbial Species and Functional Diversity in Rice Rhizosphere of High-yield Special Ecological Areas

Directory of Open Access Journals (Sweden)

PAN Li-yuan

2016-11-01

Full Text Available Taoyuan, Yunnan Province is a special eco-site which keeps the highest yield records of rice cultivation in small planting areas. Soil microbial species and functional diversity were evaluated using cultivation method and BIOLOG ecoplates. The results showed that the microbial community of the high yield region was more abundant, and the total microbial population was 2 times of the control, furthermore, the areas belonged to the healthy "bacteria" soil, which was showed as bacteria > actinomycetes > fungi. Bacteria were the dominant populations in the rhizosphere of high yielding rice field, and the yield formation of rice was not correlated with the depth of soil layers. In order to obtain more species diversity information, Shannon diversity index H, Shannon evenness index E and Simpson index D were analyzed, and the results showed that microbial community diversity and evenness were not the main differences between the high and general yield areas. Then, the functional diversity of soil microbial community was investigated through the average well color development(AWCD and diversity index analyses. The results of AWCD analysis indicated that the metabolic activity of soil microbial community in high yield paddy soils were stronger than the control. Moreover, the difference range from large to small showed as tillering stage > harvest period > seedling period > rotation period, the stronger the rice growth, the greater the difference between the high yield region and the control. At tillering stage and harvest stage, due to the vigorous plant growth, the root exudates were rich, and the microbial communities of high yield paddy soils showed a strong metabolic activity and strong ability to use carbon sources. The results of Shannon, Simpson and McIntosh indices analysis indicated that common microbial species was not a key factor affecting the yield of rice. Tillering stage was a key period for the growth of high yield rice, and many

Analytical study of dispersion relations for shear horizontal wave propagation in plates with periodic stubs

KAUST Repository

Xu, Yanlong

2015-08-01

The coupled mode theory with coupling of diffraction modes and waveguide modes is usually used on the calculations of transmission and reflection coefficients for electromagnetic waves traveling through periodic sub-wavelength structures. In this paper, I extend this method to derive analytical solutions of high-order dispersion relations for shear horizontal (SH) wave propagation in elastic plates with periodic stubs. In the long wavelength regime, the explicit expression is obtained by this theory and derived specially by employing an effective medium. This indicates that the periodical stubs are equivalent to an effective homogenous layer in the long wavelength. Notably, in the short wavelength regime, high-order diffraction modes in the plate and high-order waveguide modes in the stubs are considered with modes coupling to compute the band structures. Numerical results of the coupled mode theory fit pretty well with the results of the finite element method (FEM). In addition, the band structures\\' evolution with the height of the stubs and the thickness of the plate shows clearly that the method can predict well the Bragg band gaps, locally resonant band gaps and high-order symmetric and anti-symmetric thickness-twist modes for the periodically structured plates. © 2015 Elsevier B.V.

Interpretations of Frequency Domain Analyses of Neural Entrainment: Periodicity, Fundamental Frequency, and Harmonics.

Science.gov (United States)

Zhou, Hong; Melloni, Lucia; Poeppel, David; Ding, Nai

2016-01-01

Brain activity can follow the rhythms of dynamic sensory stimuli, such as speech and music, a phenomenon called neural entrainment. It has been hypothesized that low-frequency neural entrainment in the neural delta and theta bands provides a potential mechanism to represent and integrate temporal information. Low-frequency neural entrainment is often studied using periodically changing stimuli and is analyzed in the frequency domain using the Fourier analysis. The Fourier analysis decomposes a periodic signal into harmonically related sinusoids. However, it is not intuitive how these harmonically related components are related to the response waveform. Here, we explain the interpretation of response harmonics, with a special focus on very low-frequency neural entrainment near 1 Hz. It is illustrated why neural responses repeating at f Hz do not necessarily generate any neural response at f Hz in the Fourier spectrum. A strong neural response at f Hz indicates that the time scales of the neural response waveform within each cycle match the time scales of the stimulus rhythm. Therefore, neural entrainment at very low frequency implies not only that the neural response repeats at f Hz but also that each period of the neural response is a slow wave matching the time scale of a f Hz sinusoid.

Comparison of Periodized and Non-Periodized Resistance Training on Maximal Strength: A Meta-Analysis.

Williams, Tyler D; Tolusso, Danilo V; Fedewa, Michael V; Esco, Michael R

2017-10-01

Periodization is a logical method of organizing training into sequential phases and cyclical time periods in order to increase the potential for achieving specific performance goals while minimizing the potential for overtraining. Periodized resistance training plans are proposed to be superior to non-periodized training plans for enhancing maximal strength. The primary aim of this study was to examine the previous literature comparing periodized resistance training plans to non-periodized resistance training plans and determine a quantitative estimate of effect on maximal strength. All studies included in the meta-analysis met the following inclusion criteria: (1) peer-reviewed publication; (2) published in English; (3) comparison of a periodized resistance training group to a non-periodized resistance training group; (4) maximal strength measured by 1-repetition maximum (1RM) squat, bench press, or leg press. Data were extracted and independently coded by two authors. Random-effects models were used to aggregate a mean effect size (ES), 95% confidence intervals (CIs) and potential moderators. The cumulative results of 81 effects gathered from 18 studies published between 1988 and 2015 indicated that the magnitude of improvement in 1RM following periodized resistance training was greater than non-periodized resistance training (ES = 0.43, 95% CI 0.27-0.58; P training status (β = -0.59; P = 0.0305), study length (β = 0.03; P = 0.0067), and training frequency (β = 0.46; P = 0.0123) were associated with a change in 1RM. These results indicate that undulating programs were more favorable for strength gains. Improvements in 1RM were greater among untrained participants. Additionally, higher training frequency and longer study length were associated with larger improvements in 1RM. These results suggest that periodized resistance training plans have a moderate effect on 1RM compared to non-periodized training plans. Variation in training stimuli

Child-Langmuir flow with periodically varying anode voltage

Rokhlenko, A.

2015-01-01

Using the Lagrangian technique, we study settled Child-Langmuir flows in a one dimensional planar diodes whose anode voltages periodically vary around given positive values. Our goal is to find analytically if the average currents in these systems can exceed the famous Child-Langmuir limit found for the stationary current a long time ago. The main result of our study is that in a periodic quasi-stationary regime the average current can be larger than the Child-Langmuir maximum even by 50% compared with its adiabatic average value. The cathode current in this case has the form of rectangular pulses which are formed by a very special triangular voltage modulation. This regime, i.e., periodicity, shape of pulses, and their amplitude, needs to be carefully chosen for the best performance

The trapezoidal function lambda f/sub e/(x), is defined for fixed e element of (0,1] and for lambda element of [1,2] by lambda f/sub e/ (x) = lambda for /x-1/< 1-e and lambda f/sub e/(x) = lambda(1-/x-1/)/(1-e) for 1 greater than or equal to /x-1/greater than or equal to 1-e. For a fixed e, this is a one parameter family of endomorphisms of the interval [0,2]. The structure of the periods (or cycles) of these mappings is studied. In addition, the metric properties of the corresponding bifurcation diagrams are considered; in particular, the rate of convergence of a sequence of bifurcation points in the (x,lambda) plane is studied. It is shown to be different from that found by Feigenbaum and others for mappings which are not flat at the top. The limiting case e = 1 is of special interest. For cycles and containing a point x element of[e,2-e], the period quadruplicates instead of doubling as it does in the usual case

In order to consider whether admission to a special hostel was a desirable policy in view of the likelihood of subsequent transfer to a nursing home, this study compared the time spent by residents in a special hostel with the period in a nursing home after they were transferred out of the hostel. We also estimated the number of nursing home places necessary for residents who were transferred and studied the reasons for transfer. The setting was a special hostel in Perth, Western Australia, for 36 people with moderate or severe dementia. The periods spent in the hostel or a nursing home were calculated for all residents admitted between 1985 and 1990. Forty-two of the 84 residents admitted during the study period were transferred to nursing homes. About two thirds of the total time in the two institutions was spent in the hostel. The two principal reasons necessitating transfer to a nursing home were advancing dementia and the addition of a physical impairment. Because a major proportion of the care of selected people with dementia (who can no longer remain at home) can be undertaken in a special hostel, this facility should be included with standard hostel and nursing home in arrangements for institutional care. Between 20 and 25 nursing home places are necessary for residents transferred from a hostel of this size.

Determination of mean rainfall from the Special Sensor Microwave/Imager (SSM/I) using a mixed lognormal distribution

Science.gov (United States)

Berg, Wesley; Chase, Robert

1992-01-01

Global estimates of monthly, seasonal, and annual oceanic rainfall are computed for a period of one year using data from the Special Sensor Microwave/Imager (SSM/I). Instantaneous rainfall estimates are derived from brightness temperature values obtained from the satellite data using the Hughes D-matrix algorithm. The instantaneous rainfall estimates are stored in 1 deg square bins over the global oceans for each month. A mixed probability distribution combining a lognormal distribution describing the positive rainfall values and a spike at zero describing the observations indicating no rainfall is used to compute mean values. The resulting data for the period of interest are fitted to a lognormal distribution by using a maximum-likelihood. Mean values are computed for the mixed distribution and qualitative comparisons with published historical results as well as quantitative comparisons with corresponding in situ raingage data are performed.

Almost Periodic Solution for Memristive Neural Networks with Time-Varying Delays

Huaiqin Wu

2013-01-01

Full Text Available This paper is concerned with the dynamical stability analysis for almost periodic solution of memristive neural networks with time-varying delays. Under the framework of Filippov solutions, by applying the inequality analysis techniques, the existence and asymptotically almost periodic behavior of solutions are discussed. Based on the differential inclusions theory and Lyapunov functional approach, the stability issues of almost periodic solution are investigated, and a sufficient condition for the existence, uniqueness, and global exponential stability of the almost periodic solution is established. Moreover, as a special case, the condition which ensures the global exponential stability of a unique periodic solution is also presented for the considered memristive neural networks. Two examples are given to illustrate the validity of the theoretical results.

The complex nature of ocean pollution underscores the utility in identifying and characterizing a limited number of "indicators" that enables scientists and managers to track trends over space and time. This paper introduces a special issue on indicators of marine pollution in the North Pacific Ocean and builds on a scientific session that was held at the North Pacific Marine Science Organization. The special issue highlights studies using a variety of indicators to provide insight into the identification of legacy and emerging contaminants, the ranking of priority pollutants from various sources, and the effects of contaminants on ecosystem health in the North Pacific Ocean. Examples include the use of mussels to illustrate spatial and temporal trends of a number of contaminants following the 2011 tsunami in Japan, the use of molecular marker (linear alkylbenzenes, hopanes, and polycyclic aromatic hydrocarbons) profiles to identify pollution sources, and the use of plastic resin pellets to illustrate spatial trends of petroleum pollution around the world. Stable isotopes were used to strengthen the utility of the Glaucous-winged gull (Larus glaucescens) as an indicator of marine pollution. Examples also demonstrate the development and application of biomarker approaches, including gene transcripts, oxidative stress, estradiol, hatchability, and respiration and swimming behavior abnormalities, as a function of exposure to polychlorinated biphenyls, sulfur-diesel, Pinghu crude oil, galaxolide and antifouling biocides. We provide a brief review of indicators of marine pollution, identify research gaps, and summarize key findings from the articles published within the issue. This special issue represents the first compilation of research pertaining to marine pollution indicators in the North Pacific Ocean and provides guidance to inform mitigation and monitoring efforts of contaminants in the region.

van den Heuvel, Renée J F; Lexis, Monique A S; de Witte, Luc P

2017-12-01

The aim of this study was to explore the potential of ZORA robot-based interventions in rehabilitation and special education for children with severe physical disabilities. A two-centre explorative pilot study was carried out over a 2.5-month period involving children with severe physical disabilities with a developmental age ranging from 2 to 8 years. Children participated in six sessions with the ZORA robot in individual or in group sessions. Qualitative and quantitative methods were used to collect data on aspects of feasibility, usability, barriers and facilitators for the child as well as for the therapist and to obtain an indication of the effects on playfulness and the achievement of goals. In total, 17 children and seven professionals participated in the study. The results of this study show a positive contribution of ZORA in achieving therapy and educational goals. Moreover, sessions with ZORA were indicated as playful. Three main domains were indicated to be the most promising for the application of ZORA: movement skills, communication skills and cognitive skills. Furthermore, ZORA can contribute towards eliciting motivation, concentration, taking initiative and improving attention span of the children. On the basis of the results of the study, it can be concluded that ZORA has potential in therapy and education for children with severe physical disabilities. More research is needed to gain insight into how ZORA can be applied best in rehabilitation and special education.

The Influence of Multiple Specializations on Economic Performance in U.S. Metropolitan Areas

Directory of Open Access Journals (Sweden)

Saheum Hong

Full Text Available Scholars have recently been debating how economic structure affects regional economic performance. Regional economic structure typically indicates how the industries in regions are organized. The attribute of industrial organization in regions is typically measured by how the employment in a region is distributed among various sectors. If the employment in a region is highly concentrated on a limited number of sectors, that region is industrially specialized. On the contrary, when the employment is more evenly distributed among various industries, that region is highly diversified in its industrial organization. In this context, some researchers recognized that diversity and specialization are not opposite concepts. Instead, they can coexist, for example in the form of diversified specializations. In this study, this body of literature was extended by formulating an indicator to measure the extent of multiple specializations in regional economies and by examining the effect of multiple specializations on regional economic performance. Empirical analysis showed that specializing in multiple industrial pursuits helped regions to achieve both faster and more stable economic growth.

Lung procurement for transplantation occurs in approximately 20% of brain dead donors and is a major impediment to wider application of lung transplantation. We investigated the effect of lung protective management at a specialized donor care facility on lung procurement rates from brain dead donors. Our local organ procurement organization instituted a protocol of lung protective management at a freestanding specialized donor care facility in 2008. Brain dead donors from 2001 to 2007 (early period) were compared with those from 2009 to 2016 (current period) for lung procurement rates and other solid-organ procurement rates using a prospectively maintained database. An overall increase occurred in the number of brain dead donors during the study period (early group, 791; late group, 1,333; p procurement rate (lung donors/all brain dead donors) improved markedly after the introduction of lung protective management (early group, 157 of 791 [19.8%]; current group, 452 of 1,333 [33.9%]; p procurement rate (total number of organs procured/donor) also increased during the study period (early group, 3.5 organs/donor; current group, 3.8 organs/donor; p = 0.006). Lung protective management in brain dead donors at a specialized donor care facility is associated with higher lung utilization rates compared with conventional management. This strategy does not adversely affect the utilization of other organs in a multiorgan donor. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

The purpose of this study is, first to present a 10-year monitoring of postanalytical turnaround time (TAT) adapted to different clinicians and patient situations, second to evaluate and analyse the indicators results during that period of time, and finally to show a synthetic appropriate indicator to be included in the balanced scorecard management system. TAT indicator for routine samples was devised as the percentage of certain key tests that were verified before a specific time on the phlebotomy day. A weighted mean synthetic indicator was also designed. They were calculated for inpatients at 15:00 and 12:00 and for primary care patients only at 15:00. The troponin TAT of emergency department patients, calculated as the difference between the troponin verification and registration time, was selected as the stat laboratory TAT indicator. The routine and stat TAT improved along the 10-year study period. The synthetic indicator showed the same trend. The implementation of systematic and continuous monitoring over years, promoted a continuous improvement in TAT which will probably benefit patient outcome and safety.

Specialized science.

Science.gov (United States)

Casadevall, Arturo; Fang, Ferric C

2014-04-01

As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

This report presents details pertaining to an exercise conducted as part of the NKS-B programme using synthetic gamma ray spectra to simulate the type of data that may be encountered in the interception of material potentially containing special nuclear materials. A range of scenarios were developed involving sources that may or may not contain special nuclear materials. Gamma spectral data was provided to participants as well as ancillary data and participants were asked, under time constraint, to determine whether or not the data was indicative of circumstances involving special nuclear materials. The situations varied such that different approaches were required in order to obtain the correct result in each context. In the majority of cases participants were able to correctly ascertain whether or not the situations involved special nuclear material. Although fulfilling the primary goal of the exercise, some participants were not in a position to correctly identify with certainty the material involved, Situations in which the smuggled material was being masked by another source proved to be the most challenging for participants.

Detecting periodic oscillations in astronomy data: revisiting wavelet analysis with coloured and white noise

Science.gov (United States)

Xu, Chang

2017-04-01

The intrinsic random variability of an astronomical source hampers the detection of possible periodicities that we are interested in. We find that a simple first-order autoregressive [AR(1)] process gives a poor fit to the power decay in the observed spectrum for astrophysical sources and geodetic observations. Thus, appropriate background noise models have to be chosen for significance tests to distinguish real features from the intrinsic variability of the source. Here we recall the wavelet analysis with significance and confidence testing but extend it with the generalized Gauss Markov stochastic model as the null hypothesis, which includes AR(1) and a power law as special cases. We exemplify this discussion with real data, such as sunspot number data, geomagnetic indices, X-ray observations, as well as a Global Positioning System (GPS) position time series.

Utility of 99mTc-MAG3 perfusion indices in the evaluation of renal transplant function during early post-transplantation period

International Nuclear Information System (INIS)

Kim, Sung Hoon; Chung, Soo Kyo

2000-01-01

We have examined the utility of 99m Tc-MAG3 perfusion indices for assessing renal graft function in early post-transplantation period. Our study included 80 renal transplant recipients (48 men and 32 women, mean age:40.3 years). Diagnosis was based on biopsy, laboratory data and clinical course. Renal scintigraphy (RS) was obtained using 100 MBq of 99m Tc-MAG3 from 11 days to 23 days of kidney transplantation. We measured 5 indices in whole-kidney (WK) and cortical (C) renograms; Hilson's perfusion index (PI), transplant perfusion index (TP) and transplant function index (TF) as perfusion parameter, and the time to peak activity (Tmax) and the ratio of renal counts at 20 min to that at 3 min (K20/3) as functional parameter. The diagnoses at the day of RS were normal graft (NG) in 44, acute rejection (AR) in 14, acute tubular necrosis (ATN) in 10, and Cyclosporine A nephrotoxicity (CsA) in 12. TP and TF were significantly decreased in AR, ATN and CsA, compared to those in NG. K20/3 of AR and ATN were significantly greater than that of NG. WK-Tmax of AR was significantly longer than than that of NG. K20.3 of AR and C-K20/3 of ATN were significantly prolonged relative to those of CsA. There were no statistically significant perfusion indices among complication groups. TP and TF reflecting microperfusion and initial tubular extraction are reliable in assessing graft function. However, it is required to correlate perfusion indices with functional indices and clinical course in differentiating from one another among complication groups

A new method is described for transfer of the measure of unit volume activity of radioactive aerosols from the state special standard to the working instruments in the stage of regular operation. The differences from existing methods are examined. The principal distinction of the new method is the possibility of direct (rather than through the conversion factor) determination and subsequent testing of the fundamental meteorological characteristics of the instrument by means of special aerosol sources, which fosters a significant reduction in individual components of the indicated errors.

Equivariant surgery theories and their periodicity properties

CERN Document Server

Dovermann, Karl Heinz

1990-01-01

The theory of surgery on manifolds has been generalized to categories of manifolds with group actions in several different ways. This book discusses some basic properties that such theories have in common. Special emphasis is placed on analogs of the fourfold periodicity theorems in ordinary surgery and the roles of standard general position hypotheses on the strata of manifolds with group actions. The contents of the book presuppose some familiarity with the basic ideas of surgery theory and transformation groups, but no previous knowledge of equivariant surgery is assumed. The book is designed to serve either as an introduction to equivariant surgery theory for advanced graduate students and researchers in related areas, or as an account of the authors' previously unpublished work on periodicity for specialists in surgery theory or transformation groups.

Vaara, Jani P; Kokko, Juha; Isoranta, Manne; Kyröläinen, Heikki

2015-11-01

A high volume of military training has been shown to compromise muscle strength development. We examined effects of added low-volume resistance training during special military training (ST) period, which took place after basic training period. Male conscripts (n = 25) were assigned to standardized ST with added resistance training group (TG, n = 13) and group with standardized ST only (control) (CG, n = 12). Standardized ST with added resistance training group performed 2 resistance training sessions per week for 8 weeks: hypertrophic strength (weeks 1-3), maximal strength (weeks 4-6) and power training (weeks 7-8). Maximal strength tests, load carriage performance (3.2 km, 27 kg), and hormone concentrations were measured before and after ST (mean ± SD). Both groups improved similarly in their load carriage performance time (TG: 1,162 ± 116 seconds vs. 1,047 ± 81 seconds; CG: 1,142 ± 95 seconds vs. 1,035 ± 81 seconds) (p < 0.001) but decreased maximal strength of the lower extremities (TG: 5,250 ± 1,110 N vs. 4,290 ± 720 N; CG: 5,170 ± 1,050 N vs. 4,330 ± 1,230 N) and back muscles (TG: 4,290 ± 990 N vs. 3,570 ± 48 N; CG: 3,920 ± 72 N vs. 3,410 ± 53 N) (p ≤ 0.05). Maximal strength of the upper extremities improved in CG (1,040 ± 200 N vs. 1,140 ± 200 N) (p ≤ 0.05) but not in TG. Maximal strength of the abdominal muscles improved in TG (3,260 ± 510 N vs. 3,740 ± 75 N) (p ≤ 0.05) but not in CG. Testosterone concentration increased in CG (15.2 ± 3.6 nmol·L⁻¹ vs. 21.6 ± 5.0 nmol·L⁻¹) (p < 0.01) but not in TG (18.6 ± 4.3 nmol·L⁻¹ vs. 19.5 ± 9.4 nmol·L⁻¹). In conclusion, interference with strength gains might be related to the high volume of aerobic activities and too low volume of resistance training during ST. To develop strength characteristics, careful periodization and individualization should be adopted in ST.

Primary prevention of psychiatric illness in special populations.

Science.gov (United States)

Sajatovic, Martha; Sanders, Renata; Alexeenko, Lada; Madhusoodanan, Subramoniam

2010-11-01

Some populations appear to be particularly vulnerable to the development of psychiatric symptomatology related to life events and biologic or social/cultural factors. Such groups include individuals who have experienced traumatic events, military personnel, individuals with serious medical conditions, postpartum women, and immigrants. This study reviews the literature regarding primary prevention of psychiatric disorders in special populations and identifies a variety of universal, selective, and indicated prevention measures aimed at minimizing the psychiatric sequelae in these groups. The authors reviewed the literature regarding the prevention of psychiatric symptoms in trauma/abuse victims, individuals in the military, oncology patients, patients with diabetes, pregnant/postpartum women, and immigrants. The literature on primary prevention of psychiatric illness in the special populations identified is rather limited. Universal prevention may be beneficial in some instances through public awareness campaigns and disaster planning. In other instances, more specific and intensive interventions for individuals at high risk of psychiatric illness may improve outcomes, for example, crisis counseling for those who have experienced severe trauma. Primary prevention of psychiatric illness may be an attainable goal via implementation of specific universal, selected, and indicated primary prevention measures in special populations.

The performance indicators of model projects. A special evaluation

International Nuclear Information System (INIS)

1995-11-01

As a result of the acknowledgment of the key role of the Model Project concept in the Agency's Technical Co-operation Programme, the present review of the objectives of the model projects which are now in operation, was undertaken, as recommended by the Board of Governors, to determine at an early stage: the extent to which the present objectives have been defined in a measurable way; whether objectively verifiable performance indicators and success criteria had been identified for each project; whether mechanisms to obtain feedback on the achievements had been foreseen. The overall budget for the 23 model projects, as approved from 1994 to 1998, amounts to $32,557,560, of which 45% is funded by Technical Co-operation Fund. This represents an average investment of about $8 million per year, that is over 15% of the annual TC budget. The conceptual importance of the Model Project initiative, as well as the significant funds allocated to them, led the Secretariat to plan the methods to be used to determine their socio-economic impact. 1 tab

Bone fractures as indicators of intentional violence in the eastern Adriatic from the antique to the late medieval period (2nd-16th century AD).

Slaus, Mario; Novak, Mario; Bedić, Zeljka; Strinović, Davor

2012-09-01

To test the historically documented hypothesis of a general increase in deliberate violence in the eastern Adriatic from the antique (AN; 2nd-6th c.) through the early medieval (EM; 7th-11th c.) to the late-medieval period (LM; 12th-16th c.), an analysis of the frequency and patterning of bone trauma was conducted in three skeletal series from these time periods. A total of 1,125 adult skeletons-346 from the AN, 313 from the EM, and 466 from the LM series-were analyzed. To differentiate between intentional violence and accidental injuries, data for trauma frequencies were collected for the complete skeleton, individual long bones, and the craniofacial region as well as by type of injury (perimortem vs. antemortem). The results of our analyses show a significant temporal increase in total fracture frequencies when calculated by skeleton as well as of individuals exhibiting one skeletal indicator of deliberate violence (sharp force lesions, craniofacial injuries, "parry" fractures, or perimortem trauma). No significant temporal increases were, however, noted in the frequencies of craniofacial trauma, "parry" fractures, perimortem injuries, or of individuals exhibiting multiple skeletal indicators of intentional violence. Cumulatively, these data suggest that the temporal increase in total fracture frequencies recorded in the eastern Adriatic was caused by a combination of factors that included not only an increase of intentional violence but also a significant change in lifestyle that accompanied the transition from a relatively affluent AN urban lifestyle to a more primitive rural medieval way of life.

This, in turn, requires specialized teaching aids, which in their harmonized body are capable to provide training the generalists (multi-discipline specialists to meet a number of specific requirements imposed by this status.One of the features of mentally structured approach that provides the maximum efficiency of training the MIC technical elite is a conceptual statement that it is not only a user or a student (the subjects of the cognitive process who needs to be fitted in the specialty content of a particular subject matter. The syllabus itself (i.e. the objects of a subject matter also needs to be finetuned or adapted to psychophysiological capabilities of users (students in accordance with entitative functioning principles of memory and thinking.In other words, the concept of mentally structured presentation of information materials is that they should not be a projection of subject matter logics only, but also a projection of logics of mental (psychophysiological capability of users or students being subjects of cognitive process. Stated differently, the bridge needs to be built from two harmoniously augmenting each other sides, both from the side of human mental capabilities and from the side of content complexity of the subject matter studied.For this purpose, a special analysis of the operation aspects of the human brain functional systems has been conducted. It was found that functional asymmetry of cerebral hemyspheres has a fractal-quantum logical structure for processing information arriving at the brain input.Dextrocerebral structural components form, primarily, a logical structure of so-called mental fractals

Currently, major companies have reported their environmental indicators based on specialized guides, such as the CDP (Carbon Disclosure Project) and the GRI (Global Reporting Initiative), enumerating the most important indicators for the company activities. However, the GRI as other bibliographies of this subject does not include specific indicators for the nuclear area, leaving a significant gap to be considered for the measurement of environmental performance of this industry. Therefore, it becomes relevant to raise the following questions. May the nuclear sector use the same indicators of the non-nuclear industry? Are these indicators effective in demonstrating environmental commitment? In this work, a discussion of the indicators for the nuclear area and the CTMSP will take place. (author)

Assessment of dentally related functional competency for older adults with cognitive impairment--a survey for special-care dental professionals.

Science.gov (United States)

Chen, Xi; Clark, Jennifer J J

2013-01-01

This survey was to study whether and how dental professional assess dental-related function in older adults with cognitive impairment (OACI). An invitation was sent to 525 special-care dental professionals, followed by a reminder in 2 weeks. Thirteen percent of the targeted participants completed the survey. Among them, 88% completed a hospital dentistry, geriatric dentistry, or other postgraduate training program. Nearly 70% of the respondents considered somewhat to very difficult to assess dentally related function; 45% did not ever or did not regularly assess dental-related function for OACI. Dental-related functional assessments were often based on a subjective, unstructured approach. Only 6% of the respondents routinely used standard instruments to assess the patients' function. These results indicate that an objective functional assessment based on a standardized instrument has not been routinely incorporated into dental care for OACI, raising concerns for quality of care in this vulnerable population. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

Timely detection and management of acutely deteriorating patients can save lives. Tuen Mun Hospital (TMH), a 1800-bed acute tertiary hospital serving more than 1.06 million populations in Hong Kong, is exploring to quantitatively monitor serious clinical deterioration (SCD) and uses it to guide patient care improvement initiatives. Literature review on definition and measurement of SCD was conducted. Monthly SCD rates of TMH were first calculated according to the published methodology and benchmarked against those of international centres. A refined composite clinical indicator good for local use was compiled. In the second phase, p-control charts of SCD have been plotted based on cumulative data. TMH's performance was comparable with that of international centres. SCD on p-control charts has been plotting since January 2013. There were peaks in all 4 SCD rates during the winter surge period in 2013-2014. In the third phase, multiple measures have been taking to reduce the SCD rates including targeting the 3 main factors of winter surge situation. We are delighted to observe that the pattern did not repeat in the rate of cardiac arrest without do not attempt cardiopulmonary resuscitation (DNACPR) and rate of death without DNACPR in the same period in 2014-2015. SCD becomes a clinical governance tool to monitor the performance of clinical teams in treating acutely deteriorating patients in TMH. Any abnormal patterns or indications of special cause variations in the control charts would alert leaders to look for root causes of special cause variations and manage accordingly. We hope that this project will extend to corporate level and become a sustainable clinical indicator to guide audits, quality improvement initiatives and strategic planning. © 2016 John Wiley & Sons, Ltd.

Special geometry

International Nuclear Information System (INIS)

Strominger, A.

1990-01-01

A special manifold is an allowed target manifold for the vector multiplets of D=4, N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds and c=9, (2,2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold M of complex dimension n is characterized by the existence of a holomorphic Sp(2n+2,R)xGL(1,C) vector bundle over M with a nowhere-vanishing holomorphic section Ω. The Kaehler potential on M is the logarithm of the Sp(2n+2,R) invariant norm of Ω. (orig.)

Hydrometeorological aspects of the Real-Time Ultrafinescale Forecast Support during the Special Observing Period of the MAP*

Directory of Open Access Journals (Sweden)

R. Benoit

2003-01-01

Full Text Available During the Special Observation Period (SOP, 7 September–15 November, 1999 of the Mesoscale Alpine Programme (MAP, the Canadian Mesoscale Compressible Community Model (MC2 was run in real time at a horizontal resolution of 3 km on a computational domain of 350☓300☓50 grid points, covering the whole of the Alpine region. The WATFLOOD model was passively coupled to the MC2; the former is an integrated set of computer programs to forecast flood flows, using all available data, for catchments with response times ranging from one hour to several weeks. The unique aspect of this contribution is the operational application of numerical weather prediction data to forecast flows over a very large, multinational domain. An overview of the system performance from the hydrometeorological aspect is presented, mostly for the real-time results, but also from subsequent analyses. A streamflow validation of the precipitation is included for large basins covering upper parts of the Rhine and the Rhone, and parts of the Po and of the Danube. In general, the MC2/WATFLOOD model underestimated the total runoff because of the under-prediction of precipitation by MC2 during the MAP SOP. After the field experiment, a coding error in the cloud microphysics scheme of MC2 explains this underestimation to a large extent. A sensitivity study revealed that the simulated flows reproduce the major features of the observed flow record for most of the flow stations. The experiment was considered successful because two out of three possible flood events in the Swiss-Italian border region were predicted correctly by data from the numerical weather models linked to the hydrological model and no flow events were missed. This study has demonstrated that a flow forecast from a coupled atmospheric-hydrological model can serve as a useful first alert and quantitative forecast.

Affective changes during the postpartum period: Influences of genetic and experiential factors.

Science.gov (United States)

Agrati, Daniella; Lonstein, Joseph S

2016-01-01

This article is part of a Special Issue "Parental Care". The postpartum period involves some truly transformational changes in females' socioemotional behaviors. For most female laboratory rodents and women, these changes include an improvement in their affective state, which has positive consequences for their ability to sensitively care for their offspring. There is heterogeneity among females in the likelihood of this positive affective change, though, and some women experience elevated anxiety or depression (or in rodents anxiety- or depression-related behaviors) after giving birth. We aim to contribute to the understanding of this heterogeneity in maternal affectivity by reviewing selected components of the scientific literatures on laboratory rodents and humans examining how mothers' physical contact with her infants, genetics, history of anxiety and depression and early-life and recent-life experiences contribute to individual differences in postpartum affective states. These studies together indicate that multiple biological and environmental factors beyond female maternal state shape affective responses during the postpartum period, and probably do so in an interactive manner. Furthermore, the similar capacity of some of these factors to modulate anxiety and depression in human and rodent mothers suggests cross-species conservation of mechanisms regulating postpartum affectivity.

Air quality indicators

International Nuclear Information System (INIS)

Clench-Aas, Jocelyn; Guerreiro, Cristina; Bartonova, Alena

1999-06-01

This report proposes and describes in detail several air quality indicators that may be used to describe population exposure. The suggested indicators account for temporal and spatial patterns of pollution and movements of individuals between different micro-environments. The Air Quality Indicator /AQI) should represent both the spatial and temporal aspects of pollution exposure that may have important effects on health. Two indicators are needed, the Population Air Quality Indicator and the Individual Air Quality Indicator. Mean concentrations, 98th percentile and maximum values are the traditional indicators for estimating exposure. the temporal variability of PM-10 and NO 2 , however, is here described by means of: 1) The rate of change of pollution as the difference between two consecutive hourly values and of 2) episodes, described in terms of number, duration and winter episode period, maximum concentration in the episode and integrated episode exposure (episode AOT50/100). The spatial variation of AQIs can be described in several ways, e.g.: 1) Concentrations in neighbouring grid squares can be compared as an indication of spatial variation and 2) point estimates can be compared to grid values for a description of variation within a grid. Both methods are presented here. A test of the representativity of static point estimates for pollution exposure is to compare them to an estimate of air pollution exposure accounting for movements between different locations, obtained using diaries. The ultimate aim of AQIs is to describe the population exposure to ambient pollution. This is done by estimating the number of people exposed using different characteristics of AQIs. The data used to describe these indicators originates from dispersion modelling of short-term air pollution concentrations in Oslo. Two series of data are used. One represents hour-for hour concentrations in the 1 km 2 grid system covering the city of Oslo, winter 1994/95, calculated by the grid

Design issues for cryogenic cooling of short period superconducting undulators

International Nuclear Information System (INIS)

Green, M.A.; Dietderich, D.R.; Marks, S.; Prestemon, S.O.; Schlueter, R.D.

2003-01-01

Superconducting insertion devices, which produce periodic magnetic fields, have been built and installed in a number of synchrotron-light source storage-rings. For the most part, these devices have been wigglers, which have relatively long period lengths. This report concerns itself with the special cryogenic issues associated with short period undulators. The motivation for considering the incorporation of superconducting technology in insertion device designs is to achieve higher magnetic fields than can be achieved with more conventional permanent magnet technology. Since the peak field decreases sharply with increased magnet gap to period ratio, the cryogenic design of the magnet system is crucial. In particular, the insulation required for a warm vacuum bore device is impractical for short period undulators. This report describes the issues that are related to a cold bore (∼4 K) and an intermediate temperature bore (30 to 70 K) designs. The criteria for the use of small cryocoolers for cooling a short period undulator are presented. The problems associated with connecting small coolers to an undulator at 4.2 K are discussed

Bone marrow examination: Indications and diagnostic value

International Nuclear Information System (INIS)

Bashawri, Layla A.

2002-01-01

Objective was to identify the main indications for bone marrow examination in a University hospital setup and the most common diagnoses encountered. To also identify the extent of correlation, if any, between the preliminary diagnosis and the result of the final bone marrow diagnosis. The requests and reports of all bone marrow biopsies and aspirations carried out during a 12-year period from January 1988 through to December 1999, in King Fahd Hospital of the University, Al Khobar, Kingdom of Saudi Arabia were retrospectively reviewed. The information extracted included the main indications for performing this procedure, age groups involved, and the most common diagnoses encountered. A specially designed form was used for this purpose and the data was analyzed using the statistical package for social sciences. Randomly selected slides of the most common diagnoses were reviewed to concur with the diagnosis. There was a total of 1813 bone marrow biopsies or aspirations, or both, performed. The main indications for bone marrow examination in a descending order of frequency were the following: The diagnosis and management of acute leukemia 403 (22.2%), staging for lymphoma 276 (15.2%), evaluation of pancytopenia 215 (11.9%), thrombocytopenia 173 (9.5%), investigation of anemia 151 (8.3%), fever (pyrexia of unknown origin) 130 (7.2%), lymphadenopathy 120 (6.6%), and hepatosplenomegaly 80 (4.4%). The most common diagnoses encountered were: acute lymphoblastic leukemia 242 (13.3%), immune thrombocytopenia 123 (6.8%), acute myeloblastic leukemia 80 (4.4%), hypersplenism 79 (4.4%), chronic granulocytic leukemia 73 (4.0%), megaloblastic anemia 66 (3.6%), bone marrow positive for lymphomatous infiltration 63 (3.5%), chronic lymphocytic leukemia 40 (2.2%), and multiple myeloma 32 (1.8%). This study confirms that bone marrow examination is a very important investigation for establishing the diagnosis in many conditions, especially hematological neoplasms. The most common

To find whether better compliance with the indicators of procedure of a hypertension monitoring programme guarantees better control in the final blood pressure figures. Descriptive cross-sectional study. Gòtic Area Health Centre, Barcelona. Annual audit through random sampling of the computerised records of all the hypertense patients attended at the centre in each of 5 years (1992, n = 337; 1993, n = 318; 1994, n = 322; 1995, n = 325; 1996, n = 325). 1. Procedure indicators: complete physical examination took place in 1996 in only 12% of cases, proportion similar to at the start of the development of the programme (12.2%). Completion of at least two of the three records of protocols (complete physical examination, ECG and analysis) dropped during the period and did not cover half the patients. Screening of the various cardiovascular risk factors (CRF) increased markedly in the 1992-1995 period. 2. RESULTS INDICATORS: The proportion of patients under 66 with SP and DP < 140 and 99 mmHg went up from 23.2% in 1992 to 45.2% in 1996. In the over-65 age-group, it went from 58.9% in 1992 to 81.2% in 1996. The procedure indicators are still useful, in that they are necessary for designing a new hypertension programme. However, we must not forget that any health programme is designed in order to achieve good control and population impact (survival) results. The procedure is only an aid to reach these aims.

Born dry in the photoevaporation desert: Kepler's ultra-short-period planets formed water-poor

Science.gov (United States)

Lopez, Eric D.

2017-11-01

Recent surveys have uncovered an exciting new population of ultra-short-period (USP) planets with orbital periods less than a day. These planets typically have radii ≲1.5 R⊕, indicating that they likely have rocky compositions. This stands in contrast to the overall distribution of planets out to ∼100 d, which is dominated by low-density sub-Neptunes above 2 R⊕, which must have gaseous envelopes to explain their size. However, on the USP orbits, planets are bombarded by intense levels of photoionizing radiation and consequently gaseous sub-Neptunes are extremely vulnerable to losing their envelopes to atmospheric photoevaporation. Using models of planet evolution, I show that the rocky USP planets can easily be produced as the evaporated remnants of sub-Neptunes with H/He envelopes and that we can therefore understand the observed dearth of USP sub-Neptunes as a natural consequence of photoevaporation. Critically however, planets on USP orbits could often retain their envelopes if they are formed with very high-metallicity water-dominated envelopes. Such water-rich planets would commonly be ≳2 R⊕ today, which is inconsistent with the observed evaporation desert, indicating that most USP planets likely formed from water-poor material within the snow-line. Finally, I examine the special case of 55 Cancri e and its possible composition in the light of recent observations, and discuss the prospects for further characterizing this population with future observations.

Utility of {sup 99m}Tc-MAG3 perfusion indices in the evaluation of renal transplant function during early post-transplantation period

Energy Technology Data Exchange (ETDEWEB)

Kim, Sung Hoon; Chung, Soo Kyo [College of Medicine, The Catholic Univ. of Korea, Seoul (Korea, Republic of)

2000-12-01

We have examined the utility of {sup 99m}Tc-MAG3 perfusion indices for assessing renal graft function in early post-transplantation period. Our study included 80 renal transplant recipients (48 men and 32 women, mean age:40.3 years). Diagnosis was based on biopsy, laboratory data and clinical course. Renal scintigraphy (RS) was obtained using 100 MBq of {sup 99m}Tc-MAG3 from 11 days to 23 days of kidney transplantation. We measured 5 indices in whole-kidney (WK) and cortical (C) renograms; Hilson's perfusion index (PI), transplant perfusion index (TP) and transplant function index (TF) as perfusion parameter, and the time to peak activity (Tmax) and the ratio of renal counts at 20 min to that at 3 min (K20/3) as functional parameter. The diagnoses at the day of RS were normal graft (NG) in 44, acute rejection (AR) in 14, acute tubular necrosis (ATN) in 10, and Cyclosporine A nephrotoxicity (CsA) in 12. TP and TF were significantly decreased in AR, ATN and CsA, compared to those in NG. K20/3 of AR and ATN were significantly greater than that of NG. WK-Tmax of AR was significantly longer than than that of NG. K20.3 of AR and C-K20/3 of ATN were significantly prolonged relative to those of CsA. There were no statistically significant perfusion indices among complication groups. TP and TF reflecting microperfusion and initial tubular extraction are reliable in assessing graft function. However, it is required to correlate perfusion indices with functional indices and clinical course in differentiating from one another among complication groups.

Energy indicators for Norway 1990-2009; Energiindikatorer for Norge 1990-2009

Energy Technology Data Exchange (ETDEWEB)

Boeeng, Ann Christin; Isaksen, Elisabeth; Jama, Sadiya M.; Stalund, Marita

2011-07-01

The main purpose with this report is to present indicators that show the coherence between energy consumption and economic activity in Norway, and by this indicate if the energy consumption becomes more efficient. The report describes trends in energy use and energy intensity for Norway for the period 1990-2009, both at the national level and for detailed industries. The total energy consumption in Norway amounted to 282 TWh in 2009. Much of this energy is used in manufacturing industries, households, oil and gas extraction and road transport. In the period 1990-2009, the total energy consumption in Norway rose by 28 per cent. An important reason for the large increase in energy consumption in Norway is the increased activity in the oil and gas extraction and road transport.The main focus in this report is energy consumption per unit of production (activity level) in constant prices as we believe this is the most suitable indicator for energy intensity in the Norwegian economy. Energy use per unit of production has shown a decline of 29 per cent from 1990 to 2009. For comparison, energy use per unit of value added decreased by 17 per cent. The decline in energy intensity is due to several factors. Energy efficient equipment and improved productivity through technological change have played an important role together with the shifts in industrial structure towards less energy-intensive manufacturing industries, energy efficient buildings, increased outdoor temperature and increased labor productivity. Industry Specific indicators Energy use in manufacturing industries has leveled off since the late nineties and energy intensity declined 44 per cent in the period 1990-2009. The decrease reflects the closure of several energy-intensive businesses and facilities in the last ten years, while the remaining companies have shifted to more energy efficient equipment. It is important to keep in mind that 2009 was a special year due to the financial crisis, and the energy

As the gender wage gap narrows, the time allocations of men and women converge, a...

Marginal elasticity of periodic triangulated origami

Chen, Bryan; Sussman, Dan; Lubensky, Tom; Santangelo, Chris

Origami, the classical art of folding paper, has inspired much recent work on assembling complex 3D structures from planar sheets. Origami, and more generally hinged structures with rigid panels, where all faces are triangles have special properties due to having a bulk balance of mechanical degrees of freedom and constraints. We study two families of periodic triangulated origami structures, one based on the Miura ori and one based on a kagome-like pattern due to Ron Resch. We point out the consequences of the balance of degrees of freedom and constraints for these ''metamaterial plates'' and show how the elasticity can be tuned by changing the unit cell geometry.

Design patterns offer numerous advantages for software development, but can introduce inefficiency into the finished program. Program specialization can eliminate such overheads, but is most effective when targeted by the user to specific bottlenecks. Consequently, we propose to consider program specialization and design patterns as complementary concepts. On the one hand, program specialization can optimize object-oriented programs written using design patterns. On the other hand, design pat...

Dynamic synchronisation regions of a ring laser with the use of a periodic support

International Nuclear Information System (INIS)

Kuryatov, V N; Sudakov, V F

2008-01-01

The method is proposed for calculating dynamic synchronisation regions of a ring laser with a periodic frequency support of a special type. The proposed algorithm in essence taking into account the special type of the support allows the search for minimal widths of regions when the support parameters change. The widths of the regions are calculated as an example for the case of the harmonic carrier modulation as a harmonic envelope (three-frequency support) and an envelope of the 'soft' meander type (multifrequency support).

2012-04-01

From April 2007 to June 2008, stable isotope samples of all single precipitations were collected at the intervals of 5-30 min. We choose five single precipitations in Guangzhou city that happened during the freezing disaster event (from Jan. 10 to Feb. 2, 2008) in South China, aiming to investigate the variation of stable isotopes under the extremely climatic conditions and its controlling factors. The results show that the values of deltaD and delta18O in precipitations drop significantly during this freezing disaster. The analyses of the d-excess and LMWL indicate the abnormal oceanic moisture sources. Air mass trajectory tracking shows the moisture sources were characterized by the mixture of inland and marine water vapors during the freezing disaster peak period, while the long-distance oceanic moisture sources is the dominate one. Changes of stable isotope in single rain event during the freezing disaster shows three different trends, i. e, Up trend, V-shaped trend and W-shaped trend, which may be resulted from the re-evaporation, re-condensation and the related precipitation types in association with the different vapor sources and precipitation conditions.

2005-01-01

Falsifications of self-inspection records in the shrouds and of leakage rates for containment vessels at TEPCO nuclear power plants destroyed public trust in nuclear safety. The Nuclear Reactor Regulation Law and Electric Utility Law were amended to enhance the nuclear safety regulation system. The major improvements are that operators are legally required to conduct inspection (periodical operator inspection) and recording and keeping inspection results. The operator performs 'periodical operator inspection' regularly, and Nuclear and Industrial Safety Agency (NISA) performs periodical inspection' about particularly important facilities/function in safety. Sixteen opinions of well-informed persons about the nuclear reactor facility periodical inspection were presented in this special number. Interval of periodical inspection less than thirteen months was disputed. Maintenance activities should be more rationalized based on risk information. (T. Tanaka)

Leading Indicators of Distress in Danish Banks in the Period 2008-12

DEFF Research Database (Denmark)

Buchholst, Birgitte Vølund; Rangvid, Jesper

Several Danish small and medium-sized banks have become distressed during and after the global financial crisis. In this paper, a multiple logistic regression model is used to identify which factors characterize the distressed Danish banks from 2008-12. The factors are chosen from a broad range...... of variables, i.e. the model is unrestricted. The estimated model identifies the distressed banks fairly well. The variables that altogether best describe the probability of a bank becoming distressed are: a bank's excess capital in per cent of risk weighted assets, the 3 year average lending growth lagged 2...... years, property exposure, and a benchmark for stable funding (the so-called funding-ratio). The variables are all adjusted with the sector average to account for the general development during the period. Based on experiences from this and past crises the Danish FSA introduced the so-called Supervisory...

Multifractality of sectoral price indices: Hurst signature analysis of Cantillon effects in disequilibrium factor markets

Science.gov (United States)

Mulligan, Robert F.

2014-06-01

This paper presents Hurst exponent signatures from time series of aggregate price indices for the US over the 1975-2011 time period. Though all highly aggregated, these indices include both broad measures of consumer and producer prices. The constellation of prices evolves as a complex system throughout processes of production and distribution, culminating in the final delivery of output to consumers. Massive feedback characterizes this system, where the demand for consumable output determines the demand for the inputs used to produce it, and supply scarcities for the necessary inputs in turn determine the supply of the final product. Prices in both factor and output markets are jointly determined by interdependent supply and demand conditions. Fractal examination of the interplay among market prices would be of interest regardless, but added interest arises from the consideration of how these markets respond to external shocks over the business cycle, particularly monetary expansion. Because the initial impact of monetary injection is localized in specific sectors, the way the impact on prices diffuses throughout the economy is of special interest.

The best aortic prostheses have been debated for decades. The introduction of stentless aortic bioprostheses was aimed at improving hemodynamics and potentially the durability of aortic bioprostheses. Despite the good short- and long-term outcomes after implantation of stentless aortic bioprostheses, their use remains limited owing to the technically demanding implantation techniques. Nevertheless, stentless aortic bioprostheses might be of special benefit in certain indications, where they could be a valuable addition to the surgical armamentarium.

Urban economists hypothesize that industrial diversity matters for urban growth and development, but metrics for empirically testing this relationship are limited to simple concentration metrics (e.g. location quotient) or summary diversity indices (e.g. Gini, Herfindahl). As shown by recent advances in how we measure localization and specialization, these measures of industrial diversity may be subject to bias under small samples or the Modifiable Areal Unit Problem. Furthermore, empirically...

Full Text Available Special education in Brazil is defined in law as “the type of education offered preferentially in the regular classes for students with special needs education”. However, this proposal of special education has not always been defined in this way, and a factor that contributed greatly to the consolidation of special education as a specific field of study was the research and theis resulting publications. Thus, this study aimed to make a scientometric analysis in the field of special education in order to determine which are and were the main trends of research over the years, and to review literature on the history of special education. It was felt that the issue of special education has undergone major advances, with consequent recovery of the subject with special needs. The scientometric analysis in special education to suggest that there has been a great evolution in the area, including a fact explained by the large number of papers published over time and the different aspects of his publications. Reflections on scientometrics in special education characterize the global production of special education and provide input for further research are made in this area. Thus, the construction and analysis of these indicators have provided input to view the state of the art in special education.

Full Text Available Inclusive education practices on special education are quite important and discussed intensively. Within this context, teachers’ viewpoints and attitudes towards inclusive education practices are of great importance. There are many publications about special education practices in the literature review. In this article, it has been focused on inclusive education practices in special education and synthesizing the findings of studies examining teachers’ attitudes towards special education. Teachers’ attitudes towards inclusive education practices have been examined in terms of gender and special education training. There are 28 studies that met the criteria listed including the sample about the influence of the gender on the attitudes towards inclusive education and 23 studies meeting the inclusion criteria including the sample about the influence of special education training on teachers’ or prospective teachers’ attitudes. The findings of the study indicated that gender and special education training did not affect the attitudes towards inclusive education significantly. Of the moderating factors observed in the study, only the differences in teachers’ branches were seen to be of significance.

Special and Inclusive Education in Tanzania: Reminiscing the Past, Building the Future

Full Text Available Special education was introduced in Tanzania Mainland in 1950 by the Church Missionary Society. Despite its long history in the country, not many policies have clearly stipulated the need for special and inclusive education. This paper succinctly and systematically evaluates various educational reforms and policies in Tanzania, and points out some successes and embedded challenges in the development of special needs and inclusive education in Tanzania. To analyze clearly the current situation of special and inclusive education in the country, the Peter’s model and cases of some identified schools for exceptional students are used. The analysis has indicated an evolution from special to integrated and later on to inclusive education, which has led to an apparent increase in the number of schools and subsequent relatively higher enrollment figures for children with special needs. Despite this evolution, Tanzania has a long way to go, when compared to other countries in effectively achieving the provision of education to exceptional individuals. Finally, towards a new era of special and inclusive education in Tanzania, various recommendations are offered.

NPP Krsko Periodic Safety Review action plan

Bilic Zabric, T.

2006-01-01

In the current, internationally accepted, safety philosophy Periodic Safety Reviews (PSRs) are comprehensive reviews aimed at the verification that an operating NPP remains safe when judged against current safety objectives and practices and that adequate arrangements are in place to maintain an acceptable level of safety. These reviews are complementary to the routine and special safety reviews. They are long time-scale reviews intended to deal with the cumulative effects of plant ageing, modifications, operating experience and technical developments, which are not so easily comprehended over the shorter time-scale routine of safety reviews. The review was completed in 2005 and the next period will see the implementation of the action plan including some plant upgrades. The action plan lists issues that should be implemented at NPP Krsko together with associated milestones. The milestones were assumed based on best estimate resource availability and their ends can be potentially floated. In some cases, multiple corrective measures may be postulated to provide resolution for a given safety issue. The Slovenian Nuclear Safety Administration by decree approved the first periodic safety review and the implementation plan of activities arising from it. The entire implementation plan must be carried out by 15 October 2010. Report on the second periodic safety review must be submitted by the NEK not later than 15 December 2013. (author)

2011-07-01

Full Text Available Introduction. By measuring the actual effectiveness of a medical biochemistry laboratory’s business operations, we can determine the accounting measure of laboratory’s profitability, where operating expenses of the laboratory are covered by the income generated from the services. A laboratory’s financial report can be based on a profit and loss account, which shows whether or not a business entity, i.e., the laboratory, is making a profit during a particular business period. Methods. Profitability of the Specialized Medical Biochemical Laboratory (Laboratory of the General County Hospital in Našice, Croatia, was determined using the profit and loss account for 2007. Business success was expressed using the accounting measures of marginal contribution, gross income, and operating income, which could show whether or not the laboratory was operating profitably. This procedure allowed us to identify indicators of successful or unsuccessful business operations of the Laboratory. Results. According to the profit and loss account, the operating profit was 719,926 HRK, i.e., the operating margin was 11.7%, indicating that the Laboratory was operating positively. After subtracting all operating expenses per 100 income units, 11.7 units profit remained from the Laboratory’s core business. Conclusion. The Specialized Medical Biochemical Laboratory of the General County Hospital in Našice generated income, i.e., it operated at a profit. The purpose of profit and loss account was to determine the Laboratory operations that had impact on its business effectiveness and could increase the actual profitability. If the laboratory operates at a loss, and no activities are undertaken that would reverse the business toward positive, the analysis may provide information on the cost for the society as a whole of the studied laboratory within the existing healthcare system.

A new freshwater biodiversity indicator based on fish community assemblages.

Directory of Open Access Journals (Sweden)

Joanne Clavel

Full Text Available Biodiversity has reached a critical state. In this context, stakeholders need indicators that both provide a synthetic view of the state of biodiversity and can be used as communication tools. Using river fishes as model, we developed community indicators that aim at integrating various components of biodiversity including interactions between species and ultimately the processes influencing ecosystem functions. We developed indices at the species level based on (i the concept of specialization directly linked to the niche theory and (ii the concept of originality measuring the overall degree of differences between a species and all other species in the same clade. Five major types of originality indices, based on phylogeny, habitat-linked and diet-linked morphology, life history traits, and ecological niche were analyzed. In a second step, we tested the relationship between all biodiversity indices and land use as a proxy of human pressures. Fish communities showed no significant temporal trend for most of these indices, but both originality indices based on diet- and habitat- linked morphology showed a significant increase through time. From a spatial point of view, all indices clearly singled out Corsica Island as having higher average originality and specialization. Finally, we observed that the originality index based on niche traits might be used as an informative biodiversity indicator because we showed it is sensitive to different land use classes along a landscape artificialization gradient. Moreover, its response remained unchanged over two other land use classifications at the global scale and also at the regional scale.

Full Text Available The aim of this paper is to investigate how reliable are confidence indicators in forecasting the probability of expansion. We consider three Croatian Business Survey indicators: the Industrial Confidence Indicator (ICI, the Construction Confidence Indicator (BCI and the Retail Trade Confidence Indicator (RTCI. The quarterly data, used in the research, covered the periods from 1999/Q1 to 2014/Q1. Empirical analysis consists of two parts. The non-parametric Bry-Boschan algorithm is used for distinguishing periods of expansion from the period of recession in the Croatian economy. Then, various nonlinear probit models were estimated. The models differ with respect to the regressors (confidence indicators and the time lags. The positive signs of estimated parameters suggest that the probability of expansion increases with an increase in Confidence Indicators. Based on the obtained results, the conclusion is that ICI is the most powerful predictor of the probability of expansion in Croatia.

Microcomputer based shelf system to monitor special nuclear materials in storage

Nicholson, N.; Kuckertz, T.H.; Ethridge, C.D.

1980-01-01

Diversion of special nuclear material has become a matter of grave concern in recent years. Large quantities of this material are kept in long-term storage and must be inventoried periodically, resulting in a time-consuming activity that exposes personnel to additional radiation. A system that provides continuous surveillance of stored special nuclear materials has been developed. A shelf monitor has been designed using a single component microcomputer to collect data from a Geiger Muller tube that monitors gamma emissions and a scale that monitors the total weight of the special nuclear material and its container. A network of these shelf monitors reports their acquired data to a minicomputer for analysis and storage. Because a large number of these monitors is likely to be needed in most storage facilities, one objective of this program has been to develop a low cost but reliable monitor

Nonclassicality indicator for the real phase-space distribution functions

International Nuclear Information System (INIS)

Sadeghi, Parvin; Khademi, Siamak; Nasiri, Sadollah

2010-01-01

Benedict et al. and Kenfack et al. advocated nonclassicality indicators based on the measurement of negativity of the Wigner distribution functions. These indicators have some applications in quantum mechanics and quantum optics. In this paper we define a nonclassicality indicator in terms of the interference in phase space, which is applicable to some real distribution functions including those of Wigner. As a special case one may reproduce the previous results using our indicator for the Wigner distribution functions. This indicator is examined for cases of the Schroedinger cat state and the thermal states and the results are compared with those obtained by previous methods. It seems that the physical behavior of nonclassicality indicators originates in the uncertainty principle. This is shown by an onto correspondence between these indicators and the uncertainty principle.

Numerical computing of elastic homogenized coefficients for periodic fibrous tissue

Directory of Open Access Journals (Sweden)

Roman S.

2009-06-01

Full Text Available The homogenization theory in linear elasticity is applied to a periodic array of cylindrical inclusions in rectangular pattern extending to infinity in the inclusions axial direction, such that the deformation of tissue along this last direction is negligible. In the plane of deformation, the homogenization scheme is based on the average strain energy whereas in the third direction it is based on the average normal stress along this direction. Namely, these average quantities have to be the same on a Repeating Unit Cell (RUC of heterogeneous and homogenized media when using a special form of boundary conditions forming by a periodic part and an affine part of displacement. It exists an infinity of RUCs generating the considered array. The computing procedure is tested with different choices of RUC to control that the results of the homogenization process are independent of the kind of RUC we employ. Then, the dependence of the homogenized coefficients on the microstructure can be studied. For instance, a special anisotropy and the role of the inclusion volume are investigated. In the second part of this work, mechanical traction tests are simulated. We consider two kinds of loading, applying a density of force or imposing a displacement. We test five samples of periodic array containing one, four, sixteen, sixty-four and one hundred of RUCs. The evolution of mean stresses, strains and energy with the numbers of inclusions is studied. Evolutions depend on the kind of loading, but not their limits, which could be predicted by simulating traction test of the homogenized medium.

Specifically, we examined whether children receiving special education services displayed (a) greater reading or mathematics skills, (b) more frequent learning-related behaviors, or (c) less frequent externalizing or internalizing problem behaviors than closely matched peers not receiving such services. To do so, we used propensity score matching techniques to analyze data from the Early Childhood Longitudinal-Study Kindergarten Cohort, 1998-1999, a large scale, nationally representative sample of U.S. schoolchildren. Collectively, results indicate that receipt of special education services has either a negative or statistically non-significant impact on children's learning or behavior. However, special education services do yield a small, positive effect on children's learning-related behaviors.

2004-01-01

When an infant is admitted to a neonatal intensive care unit (NICU), parents seldom have the opportunity to celebrate special events in the infant's life within the context of the family. Our Rush SpecialKare Keepsakes is a program for parents of NICU infants that combines therapeutic photography, journaling, and memento preservation, with the goal of documenting the infant's birth and place within the family. The program has two distinct components: weekly scrapbooking sessions, which are free of charge to all NICU families; and Holiday Family Photo Shoots, in which infants are photographed with their family members to celebrate traditional holidays throughout the year. The program, which was conceived and implemented in January 2001, is under the direction of two NICU bedside nurses, who blend scrapbooking techniques with clinical expertise, so that weekly scrapbooking sessions are transformed into a unique type of parent support group. Data from the first 6 months of the program indicate that all 173 parent participants overwhelmingly appreciated the opportunity to attend these sessions, which they perceived as a brief respite from the NICU and an opportunity to interact with other families.

A paucity of existing research focuses on longitudinal examinations of criminal trajectories among reoffenses committed by domestic violence offenders. Specifically, few studies have longitudinally assessed whether domestic violence offenders specialize, recidivating in domestic violence assault, or generalize, committing a range of personal and property crimes. Acknowledging these research deficiencies, the current study uses longitudinal data from a cohort of 317 batterers who were processed in a domestic violence court to investigate the trajectories of domestic violence arrests and nondomestic violence arrests over a 10-year period. The degree of overlap between domestic and nondomestic violence arrest trajectory groups is examined through a cross-tabulation and chi-square analysis. Logistic and multinomial regression models are applied to identify risk factors that distinguish trajectory groups. A PROC TRAJ procedure identifies two trajectory groups for domestic violence arrests (low and high rate) and three trajectory groups for nondomestic violence arrests (very low, low, and high rate). Results indicate that specialization among domestic violence offenders is rare-prior alcohol and drug crimes predict membership in the high-rate domestic violence arrest trajectory group and prior domestic violence arrests predict membership in both the low-rate and high-rate nondomestic violence arrest trajectories. Implications for future research and policy are discussed in this article.

Full Text Available Introduction. Swimming as a sport encompasses various styles and distances (from 50 up to 1,500 meters. The correlation between sports results and general/special muscle strength seems unquestionable. Aim. The purpose of this paper is to answer the question related to maintaining the proportion between muscle strength development (which depends mainly on land-based trainings and endurance trainings in water. Material and methods. The study covered 14 leading swimmers from MKP Szczecin who specialized mainly in short and medium distances; they were members of the national senior and junior teams in the 2013/14 training year. The general strength tests were conducted at the beginning and at the end of the winter and summer preparatory periods. The following tests were performed: bench-pressing, pull-ups and bar dips. At the end of the main research period, a thrust test was conducted on land (on a swim bench, as well as a thrust test in the water. Results. All participants demonstrated progress in results between the summer season and the winter season. The range of training loads was higher in the summer due to the length of preparation (by about 100%. The individual progress was, however, very varied. Conclusions. The level of sports progress achieved by individual swimmers was greatly diversified. The relatively high level of general and special strength in the tested swimmers was linked to their need to display these motor skills while swimming. Subjects who showed the greatest progress in the general and special strength trials, displayed the biggest improvement in their swimming performance during the competition season. Swimmers with a fairly high level of strength, but a moderate sports level should analyze and improve their swimming technique. Subjects whose progress in general and special strength tests was the least significant, should try and achieve progress by developing other technical and coordination skills.

2003-01-01

A special cell morphology, cavity-like cells, was found in posterities of Saccharomyces cerevisiae treated by low-temperature air plasma with different powers. The feature of the special morphology indicates that the cavity-like cells may be formed by cellular mutation effect induced by the plasma, instead of direct cellular damage by the plasma. The results suggest that the cellular mutation effect of the low-temperature plasma is a complex process

Indications for fetal magnetic resonance imaging (MRI)

Prayer, D.

2006-01-01

Indications to perform fetal magnetic resonance imaging (MRI) are composed of common ones related to methodological problems of ultrasound (US) assessment (such as for instance hydramnios) and special ones. The latter are related to MR capability of high-resolution soft tissue contrast and an extended field of view that allows visualization of the whole fetus, even in later stages of pregnancy. The most important indications include confirmation of US findings, work-up of malformations with respect to individual prognosis and genetic background, differentiation between acquired conditions and malformations, visualization of pathologies that have to be treated surgically immediately after birth, and morphological changes of the placenta.

Addressing the oral healthcare needs of special needs children: pediatric nurses' self-perceived effectiveness.

Science.gov (United States)

Parish, Carrigan L; Singer, Richard; Abel, Stephen; Metsch, Lisa R

2014-01-01

To examine the oral health knowledge and practices of pediatric nurses who coordinate healthcare services for special needs children and to identify those factors that influenced their perceived effectiveness in managing their patients' oral health needs. Self-reported data were collected from 376 nurses employed at Children's Medical Services who responded to an online survey. Likert scale scores were used to specifically assess the nurses' perceived effectiveness in addressing the oral health needs of special needs children. Characteristics significantly associated with special needs pediatric nurses who described themselves as "effective or very effective" included: the self-perception of being very knowledgeable about basic oral health, receiving four or more hours of continuing education training, and securing dental appointments for the majority of their pediatric special needs patients with minimal waiting times. Findings reveal that oral health knowledge significantly influenced nurses' perceived effectiveness in addressing the oral health needs of special needs children, as well as their ability to secure timely dental appointments. These results support the need to incorporate oral health education into nursing curricula and expand upon the dental workforce available and willing to treat disabled patients. © 2013 Special Care Dentistry Association and Wiley Periodicals, Inc.

Complex trajectories in a classical periodic potential

International Nuclear Information System (INIS)

Anderson, Alexander G; Bender, Carl M

2012-01-01

This paper examines the complex trajectories of a classical particle in the potential V(x) = −cos (x). Almost all the trajectories describe a particle that hops from one well to another in an erratic fashion. However, it is shown analytically that there are two special classes of trajectories x(t) determined only by the energy of the particle and not by the initial position of the particle. The first class consists of periodic trajectories; that is, trajectories that return to their initial position x(0) after some real time T. The second class consists of trajectories for which there exists a real time T such that x(t + T) = x(t) ± 2π. These two classes of classical trajectories are analogous to valence and conduction bands in quantum mechanics, where the quantum particle either remains localized or else tunnels resonantly (conducts) through a crystal lattice. These two special types of trajectories are associated with sets of energies of measure 0. For other energies, it is shown that for long times the average velocity of the particle becomes a fractal-like function of energy. (paper)

Phononic crystal is now used to control acoustic waves. When the crystal goes to a larger scale, it is called periodic structure. The band gaps of the periodic structure can be reduced to range from 0.5 Hz to 50 Hz. Therefore, the periodic structure has potential applications in seismic wave reflection. In civil engineering, the periodic structure can be served as the foundation of upper structure. This type of foundation consisting of periodic structure is called periodic foundation. When the frequency of seismic waves falls into the band gaps of the periodic foundation, the seismic wave can be blocked. Field experiments of a scaled two dimensional (2D) periodic foundation with an upper structure were conducted to verify the band gap effects. Test results showed the 2D periodic foundation can effectively reduce the response of the upper structure for excitations with frequencies within the frequency band gaps. When the experimental and the finite element analysis results are compared, they agree well with each other, indicating that 2D periodic foundation is a feasible way of reducing seismic vibrations.

Specialization and medical mycology in the US, Britain and Japan.

Science.gov (United States)

Homei, Aya

2008-03-01

This paper attempts to bring new insights to a long-standing historical debate over medical specialization by analyzing the formation of medical mycology, a somewhat marginal biomedical discipline that emerged in the mid-twentieth century around studies of fungal disease in humans. The study of fungi predates that of bacteria and viruses, but from the 1880s it became eclipsed by bacteriology. However, in the postwar period, there were moves to establish medical mycology as an independent speciality. I trace the processes that led to the launch of professional societies in the United States, Britain and Japan, three major players in medical mycology, and more broadly in biomedicine. The analysis of the three different national contexts illustrates how geographical, medico-technological, epidemiological, political and social conditions gave the specialty a distinctive character in each country; this was further complicated by the different and changing medical fields in which fungal diseases were studied and treated. The three case studies show medical specialization as a process that is not simply cumulative but responds to specific historical events and developments.

Full Text Available Distributed leadership can enhance the professional learning communities of schools. The present study explored the leadership experience of Jordanian special education teachers, and their perceptions of common constraints to leadership. A mixed method design was used, including a survey (n = 136 and an interview (n = 23. Results indicated that special education teachers had little experience of leadership roles. They regarded the provision of cognitive and emotional support to colleagues as their most important leadership role, and participating in interview committees and selecting new teachers as the least important. There were no significant mean differences between male and female special education teachers in their level of enacted leadership. Level of education and years of experience were found to have a significant effect on the level of teachers’ leadership.

In the present study, the effect of Ramadan fasting in asthmatic patients and healthy control was studied. Haematological indices, inflammatory mediators, pulmonary function tests (PFT) and respiratory symptoms were evaluated in 15 asthmatic patients compared to 14 healthy matched control group before and after the one-month fasting period in Ramadan. The change in each parameter from the beginning to the end of Ramadan was calculated and referred to as "variation during Ramadan". The values of MCH, MCHC in both groups and monocyte counts in asthmatic patients, were significantly increased but platelet count was reduced in asthmatic and controls respectively compared to pre-Ramadan fasting period (Pfasting month (Pfasting month in both groups were non-significantly higher compared to pre-fasting values except FVC. Respiratory symptoms in asthmatic patients were non-significantly but wheeze-o was significantly reduced after Ramadan fasting period in asthma group (Pfasting period between two groups, although reduction of hs-CRP in asthmatic group was non-significantly higher than control group. These results show that Ramadan fasting period has no negative impact on asthma and may have some positive effect on asthma severity with regard to reduction of hs-CRP concentration and chest wheeze.

Sensitivity analysis of periodic errors in heterodyne interferometry

International Nuclear Information System (INIS)

Ganguly, Vasishta; Kim, Nam Ho; Kim, Hyo Soo; Schmitz, Tony

2011-01-01

Periodic errors in heterodyne displacement measuring interferometry occur due to frequency mixing in the interferometer. These nonlinearities are typically characterized as first- and second-order periodic errors which cause a cyclical (non-cumulative) variation in the reported displacement about the true value. This study implements an existing analytical periodic error model in order to identify sensitivities of the first- and second-order periodic errors to the input parameters, including rotational misalignments of the polarizing beam splitter and mixing polarizer, non-orthogonality of the two laser frequencies, ellipticity in the polarizations of the two laser beams, and different transmission coefficients in the polarizing beam splitter. A local sensitivity analysis is first conducted to examine the sensitivities of the periodic errors with respect to each input parameter about the nominal input values. Next, a variance-based approach is used to study the global sensitivities of the periodic errors by calculating the Sobol' sensitivity indices using Monte Carlo simulation. The effect of variation in the input uncertainty on the computed sensitivity indices is examined. It is seen that the first-order periodic error is highly sensitive to non-orthogonality of the two linearly polarized laser frequencies, while the second-order error is most sensitive to the rotational misalignment between the laser beams and the polarizing beam splitter. A particle swarm optimization technique is finally used to predict the possible setup imperfections based on experimentally generated values for periodic errors

Periodic Safety Review of Nuclear Power Plants: Experience of Member States

International Nuclear Information System (INIS)

2010-04-01

Routine reviews of nuclear power plant operation (including modifications to hardware and procedures, operating experience, plant management and personnel competence) and special reviews following major events of safety significance are the primary means of safety verification. In addition, many Member States of the IAEA have initiated systematic safety reassessments, termed periodic safety reviews, of nuclear power plants, to assess the cumulative effects of plant ageing and plant modifications, operating experience, technical developments and siting aspects. The reviews include an assessment of plant design and operation against current safety standards and practices, and they have the objective of ensuring a high level of safety throughout the plant's operating lifetime. They are complementary to the routine and special safety reviews and do not replace them. Periodic safety reviews of nuclear power plants are considered an effective way to obtain an overall view of actual plant safety, and to determine reasonable and practical modifications that should be made in order to maintain a high level of safety. They can be used as a means of identifying time limiting features of the plant in order to determine nuclear power plant operation beyond the designed lifetime. The periodic safety review process can be used to support the decision making process for long term operation or licence renewal. Since 1994, the use of periodic safety reviews by Member States has substantially broadened and confirmed its benefits. Periodic safety review results have, for example, been used by some Member States to help provide a basis for continued operation beyond the current licence term, to communicate more effectively with stakeholders regarding nuclear power plant safety, and to help identify changes to plant operation that enhance safety. This IAEA-TECDOC is intended to assist Member States in the implementation of a periodic safety review. This publication complements the

The Mediterranean area concentrates the major natural risks related to the water cycle, including heavy precipitation and flash-flooding during the fall season. The capability to predict such high-impact events remains weak because of the contribution of very fine-scale processes and their non-linear interactions with the larger scale processes. These societal and science issues motivate the HyMeX (Hydrological cycle in the Mediterranean Experiment, http://www.hymex.org/) experimental programme. HyMeX aims at a better quantification and understanding of the water cycle in the Mediterranean with emphasis on intense events. The observation strategy of HyMEX is organized in a long-term (4 years) Enhanced Observation Periods (EOP) and short-term (2 months) Special Observation Periods (SOP). HyMEX has identified 3 main Mediterranean target areas: North-West (NW), Adriatic (A) and South-East (SE). Within each target area several hydrometeorological sites for heavy rainfall and flash flooding have been set up. The hydrometeorological site in Central Italy (CI) is interested by both western and eastern fronts coming from the Atlantic Ocean and Siberia, respectively. Orographic precipitations play an important role due to the central Apennine range, which reaches nearly 3000 m (Gran Sasso peak). Moreover, convective systems commonly develop in CI during late summer and beginning of autumn, often causing localized hailstorms with cluster organized cells. Western fronts may heavily hit the Tiber basin crossing large urban areas (Rome), whereas eastern fronts can cause flash floods along the Adriatic coastline. Two major basins are involved within CI region: Tiber basin (1000 km long) and its tributary Aniene and the Aterno-Pescara basin (300 km long). The first HyMeX SOP1.1 was carried out from Sept. till Nov. 2012 in the NW target area. The Italian SOP1.1 was coordinated by the Centre of Excellence CETEMPS, University of L'Aquila, a city located in the CI heart. The CI area

Influence of Structural Corrective and Respiratory Exercises on Cardiorespiratory Indices of Male Children Afflicted with Kyphosis

Directory of Open Access Journals (Sweden)

Hasan Meamari

2017-06-01

Conclusion According to our findings, it can be concluded that there is an improvement in cardiopulmonary function indices following respiratory exercises. Keeping in mind the ease with which they can be performed and the fact they do not require special devices, it can be firmly stated that respiratory muscle exercises are more efficient than other corrective exercises during a brief intervention period (six weeks. With regard to the approved influence of structural corrective exercise in kyphosis in previous studies and its relatively inadequate influence in the present study, it seems that corrective exercises need a comparatively longer duration (probably 12 weeks to prove effective. A limitation of this study was the lack of controlling false habits in daily physical activities and postures that could have had an influence on kyphosis. Its evaluation is recommended for future studies.

It is one of the important strategies in the new period of national poverty alleviation and development to maintain the basic balance between the ecological environment and economic development, and to promote the coordinated sustainable development of economy and ecological environment. Taking six contiguous special poverty-stricken areas as the study areas, a coupling coordination evaluation method between eco-environment quality and economic development level in contiguous special poverty-stricken areas was explored in this paper. The region' s ecological poverty index system was proposed based on the natural attribute of ecological environment, and the ecological environment quality evaluation method was built up by using AHP weighting method, followed by the design of the coupling coordination evaluation method between the ecological environment indices and the county economic poverty comprehensive indices. The coupling coordination degrees were calculated and their spatial representation differentiations were analyzed respectively at district, province, city, and county scales. Results showed that approximately half of the counties in the study areas achieved the harmoniously coordinated development. However, the ecological environmental quality and the economic development in most counties could not be synchronized, where mountains, rivers and other geographic features existed roughly as a dividing line of the coordinated development types. The phenomena of dislocation between the ecological environment and economic development in state-level poor counties were more serious than those of local poor counties.

Special energies and special frequencies

International Nuclear Information System (INIS)

Endrullis, M.; Englisch, H.

''Special frequencies'' have been asserted to be zeros of the density of frequencies corresponding to a random chain of coupled oscillators. Our investigation includes both this model and the random one-dimensional Schroedinger operator describing an alloy or its discrete analogue. Using the phase method we exactly determine a bilateral Lifsic asymptotic of the integrated density of states k(E) at special energies G s , which is not only of the classical type exp(-c/vertical strokeE-E s vertical stroke 1/2 ) but also exp(-c'/vertical strokeE-E s vertical stroke) is a typical behaviour. In addition, other asymptotics occur, e.g. vertical strokeE-E c vertical stroke c '', which show that k(E) need not be C ∞ . (orig.)

Energy conservation indicators. 1982 annual report

Energy Technology Data Exchange (ETDEWEB)

Belzer, D.B.

1982-09-01

A series of Energy Conservation Indicators were developed for the Department of Energy to assist in the evaluation of current and proposed conservation strategies. As descriptive statistics that signify current conditions and trends related to efficiency of energy use, indicators provide a way of measuring, monitoring, or inferring actual responses by consumers in markets for energy services. Related sets of indicators are presented in some 40 one-page indicator summaries. Indicators are shown graphically, followed by several paragraphs that explain their derivation and highlight key findings. Indicators are classified according to broad end-use sectors: Aggregate (economy), Residential, Commercial, Industrial, Transportation and Electric Utilities. In most cases annual time series information is presented covering the period 1960 through 1981.

Finger replantation: surgical technique and indications.

Science.gov (United States)

Barbary, S; Dap, F; Dautel, G

2013-12-01

In this article, we discuss the surgical technique of finger replantation in detail, distinguishing particularities of technique in cases of thumb amputation, children fingertip replantation, ring finger avulsion, and very distal replantations. We emphasize the principles of bone shortening, the spare part concept, the special importance of nerve sutures and the use of vein graft in case of avulsion or crushing. However, even if finger replantation is now a routine procedure, a clear distinction should be made between revascularization and functional success. The indications for finger replantation are then detailed in the second part of this paper. The absolute indications for replantation are thumb, multiple fingers, transmetacarpal or hand, and any upper extremity amputation in a child whatever the level. Fingertip amputations distal to the insertion of the Flexor digitorum superficialis (FDS) are also a good indication. Other cases are more controversial because of the poor functional outcome, especially for the index finger, which is often functionally excluded. Copyright © 2013. Published by Elsevier SAS.

1983-01-01

The results are analyzed of an X-ray examination of 208 patients with traumas of the cervical region of the spinal column and spinal cord in the acute period of trauma. The authors proposed a scheme that included telespondylography in standard and oblique projections, flebospondylography, discography and pneumomyelography in the Schantz collar with a patient lying on the back. Four types of the spinal cord traumas were diagnosed: compression with osseous elements (76.92%), with sharp discs and strained epidural hematomas (3.85%), isolated contusion of the spinal cord (10.1%) and disorder of the spinal circulation (9.13%). Special emphasis was laid on clinicospondylographic correlations, a critical distance, congenital narrowing of the vertebral canal. The concept of traumatic decompression of the spinal cord was stressed. Symptoms of its contusion and trauma of the spinal circulation were indicated

Pancreaticoduodenectomy is a demanding procedure even in selected patients but becomes formidable when performed in cases of emergency. This study analyzed our experience with urgent pancreatoduodenectomies; special emphases were put on the evaluation of diagnostic means and the validation of existing indications for performance of this procedure. Three hundred one patients who underwent pancreatoduodenectomy between 1989 and 2008 were identified from a pancreatic resection database and reviewed for emergency indications. Six patients (2%) underwent emergency pancreatoduodenectomy. Indications included endoscopy-related perforation, postoperative complications, and uncontrollable intraduodenal tumor bleeding. Length of stay and occurrence of nonsurgical complications were increased in emergency compared with elective pancreatoduodenectomies. Although increased, no significant differences were found regarding mortality and surgery-related complications. Indications for emergency pancreatoduodenectomies were based on clinical decisions rather than on radiologic diagnostics. Urgent pancreatic head resections may be considered as an option in selected patients if handling of local complications by interventional measures or limited surgery seems unsafe.

Environmental indicators are powerful tools for tracking environmental changes, measuring environmental performance, and informing policymakers. Many diverse environmental indicators, including agricultural environmental indicators, are currently in use or being developed. This special collection of technical papers expands on the peer-reviewed literature on environmental indicators and their application to important current issues in the following areas: (i) model-derived indicators to indicate phosphorus losses from arable land to surface runoff and subsurface drainage, (ii) glutathione-ascorbate cycle-related antioxidants as early-warning bioindicators of polybrominated diphenyl ether toxicity in mangroves, and (iii) assessing the effectiveness of using organic matrix biobeds to limit herbicide dissipation from agricultural fields, thereby controlling on-farm point-source pollution. This introductory review also provides an overview of environmental indicators, mainly for agriculture, with examples related to the quality of the agricultural soil-water-air continuum and the application of model-derived indicators. Current knowledge gaps and future lines of investigation are also discussed. It appears that environmental indicators, particularly those for agriculture, work efficiently at the field, catchment, and local scales and serve as valuable metrics of system functioning and response; however, these indicators need to be refined or further developed to comprehensively meet community expectations in terms of providing a consistent picture of relevant issues and/or allowing comparisons to be made nationally or internationally.

Deinega, Alexei; Belousov, Sergei; Valuev, Ilya

2009-03-15

A hybrid transfer-matrix finite-difference time-domain (FDTD) method is proposed for modeling the optical properties of finite-width planar periodic structures. This method can also be applied for calculation of the photonic bands in infinite photonic crystals. We describe the procedure of evaluating the transfer-matrix elements by a special numerical FDTD simulation. The accuracy of the new method is tested by comparing computed transmission spectra of a 32-layered photonic crystal composed of spherical or ellipsoidal scatterers with the results of direct FDTD and layer-multiple-scattering calculations.

A transitional snake from the Late Cretaceous period of North America.

Longrich, Nicholas R; Bhullar, Bhart-Anjan S; Gauthier, Jacques A

2012-08-09

Snakes are the most diverse group of lizards, but their origins and early evolution remain poorly understood owing to a lack of transitional forms. Several major issues remain outstanding, such as whether snakes originated in a marine or terrestrial environment and how their unique feeding mechanism evolved. The Cretaceous Coniophis precedens was among the first Mesozoic snakes discovered, but until now only an isolated vertebra has been described and it has therefore been overlooked in discussions of snake evolution. Here we report on previously undescribed material from this ancient snake, including the maxilla, dentary and additional vertebrae. Coniophis is not an anilioid as previously thought a revised phylogenetic analysis of Ophidia shows that it instead represents the most primitive known snake. Accordingly, its morphology and ecology are critical to understanding snake evolution. Coniophis occurs in a continental floodplain environment, consistent with a terrestrial rather than a marine origin; furthermore, its small size and reduced neural spines indicate fossorial habits, suggesting that snakes evolved from burrowing lizards. The skull is intermediate between that of lizards and snakes. Hooked teeth and an intramandibular joint indicate that Coniophis fed on relatively large, soft-bodied prey. However, the maxilla is firmly united with the skull, indicating an akinetic rostrum. Coniophis therefore represents a transitional snake, combining a snake-like body and a lizard-like head. Subsequent to the evolution of a serpentine body and carnivory, snakes evolved a highly specialized, kinetic skull, which was followed by a major adaptive radiation in the Early Cretaceous period. This pattern suggests that the kinetic skull was a key innovation that permitted the diversification of snakes.

Full Text Available The specificities of general and special school teachers’ work might influence their career differently. The aim of the study was to examine the career cycle of these teachers. A survey was conducted on a sample of 120 teachers from general and 95 from special schools. Five stages of career cycle were discovered: induction, competency building and enthusiasm, career frustration, stagnation, career wind-down. Results indicate that age, gender, intrinsic, and extrinsic factors of career choice can influence teachers’ career cycle. When these factors are controlled, special school teachers experience less enthusiasm and more willingness to retire than general school teachers.

[Mathematics - astronomy - astrology special library].

Gluch, Sibylle

2011-01-01

About 1560 Elector August of Saxony created an unusual library--one distinguished within its period by both its specialization and location. Situated within the Kunstkammer this library was mostly dedicated to the mathematical sciences and related disciplines. It contained works by the most important authors on mathematics, astronomy, and astrology from the classical, medieval, and early modern periods. This essay traces the formation and composition of August's library, and examines its function: What kind of relationship existed between the library and the Kunstkammer? In what way did the library mirror the interests of the Elector, and to what extend does it permit inferences regarding the Elector's knowledge of mathematics? From the analysis August emerges not as a specialist with a deep understanding of mathematics, but as a particular aficionado of mathematical applications. As a practitioner and general follower of the mathematical arts he took part in a far-reaching intellectual network the center of which lay in the University of Wittenberg. Here, Melanchthon had effectively strengthened the importance of the mathematical disciplines within the university curriculum. He regarded mathematics as the foremost science, arguing that before all other disciplines its method enabled man to recognize the harmonic order of the world, and to discern divine providence. Thus, mathematics offered consoling stability and support in an often seemingly chaotic world torn by religious controversies. This kind of esteem for the mathematical sciences did not presuppose expert knowledge. Hence, the fact that August does not appear to have read the mathematical books he collected does not come as a contradiction. On the contrary, for August it sufficed to recognize the potential of the mathematical sciences, which he brought into life through the creation of a specialized library that developed a rhetoric of its own. The collection of his Kunstkammer library spoke of a

This paper presents data on the current operating status and the safety indicators (SI) of the six nuclear power units in Taiwan. Analysis of the data collected in a six-year period has been made to obtain trends for each safety indicator. An overview of the trends of the plant operational data during the same period are also provided and discussed. On the whole, the trends of safety indicators are improving during the observed period 1991-1996. The plant operational data have depicted coherent improvement with the safety indicator trends. This result supports the premise that improvements in safety performance and in operational reliability are correspondingly inter-dependent. Both the safety indicators quarterly report and the annual report are available to the public. The public can also approach this information from the AEC's World Wide Web site (http://www.aec.gov.tw). (author)

Providing quality education means to respond to the diversity in the classroom. The teacher is a key figure in responding to the various educational needs presented by students. Specifically, special education professionals are of great importance as they are the ones who lend their support to regular classroom teachers and offer specialized educational assistance to students who require it. Therefore, special education is different from what takes place in the regular classroom, demanding greater commitment by the teacher. There are certain behaviors, considered good teaching practices, which teachers have always been connected with to achieve good teaching and good learning. To ensure that these teachers are carrying out their educational work properly it is necessary to evaluate. This means having appropriate instruments. The Observational Protocol for Teaching Functions in Primary School and Special Education (PROFUNDO-EPE, v.3., in Spanish) allows to capture behaviors from these professionals and behavioral patterns that correspond to good teaching practices. This study evaluates the behavior of two special education teachers who work with students from different educational stages and educational needs. It reveals that the analyzed teachers adapt their behavior according the needs and characteristics of their students to the students responding more adequately to the needs presented by the students and showing good teaching practices. The patterns obtained indicate that they offer support, help and clear guidelines to perform the tasks. They motivate them toward learning by providing positive feedback and they check that students have properly assimilated the contents through questions or non-verbal supervision. Also, they provide a safe and reliable climate for learning.

Psychosocial Research on the International Space Station: Special Privacy Considerations

Science.gov (United States)

Kanas, N.; Salnitskiy, V.; Ritsher, J.; Grund, E.; Weiss, D.; Gushin, V.; Kozerenko, O.

Conducting psychosocial research with astronauts and cosmonauts requires special privacy and confidentiality precautions due to the high profile nature of the subject population and to individual crewmember perception of the risks inherent in divulging sensitive psychological information. Sampling from this small population necessitates subject protections above and beyond standard scientific human subject protocols. Many of these protections have relevance for psychosocial research on the International Space Station. In our previous study of psychosocial issues involving crewmembers on the Mir space station, special precautions were taken during each phase of the missions. These were implemented in order to gain the trust necessary to ameliorate the perceived risks of divulging potentially sensitive psychological information and to encourage candid responses. Pre-flight, a standard confidentiality agreement was provided along with a special layman's summary indicating that only group-level data would be presented, and subjects chose their own ID codes known only to themselves. In-flight, special procedures and technologies (such as encryption) were employed to protect the data during the collection. Post-flight, an analytic strategy was chosen to further mask subject identifiers, and draft manuscripts were reviewed by the astronaut office prior to publication. All of the eligible five astronauts and eight cosmonauts who flew joint US/Russian missions on the Mir were successfully recruited to participate, and their data completion rate was 76%. Descriptive analyses of the data indicated that there was sufficient variability in all of the measures to indicate that thoughtful, discriminating responses were being provided (e.g., the full range of response options was used in 63 of the 65 items of the Profile of Mood States measure, and both true and false response options were used in all 126 items of the Group Environment and the Work Environment measures).

2012-01-01

We review the special geometry of N = 2 supersymmetric vector and hypermultiplets with emphasis on recent developments and applications. A new formulation of the local c-map based on the Hesse potential and special real coordinates is presented. Other recent developments include the Euclidean version of special geometry, and generalizations of special geometry to non-supersymmetric theories. As applications we discuss the proof that the local r-map and c-map preserve geodesic completeness, and the construction of four- and five-dimensional static solutions through dimensional reduction over time. The shared features of the real, complex and quaternionic version of special geometry are stressed throughout.

Full Text Available Objective: To analyze the vaccine schedule for preterm infants in a program of special immunobiologicals. Methods: A documental study conducted at a Reference Center of Special Immunobiologicals (CREATE situated in a general hospital of tertiary care in pediatrics. The sample consisted of 112 newborns with gestational age below 37 weeks and weighing less than 2500g, suitable for vaccination, assisted in 2006-2007. Data collection was done from registration forms, reference records and registers of control of special immunobiologicals’ administration, in year 2008. Results: The results showed that 22 (20% newborns were weighing between 1000 and 1499g. Regarding gestational age, 39 (35% were born between 30 and 34 weeks of pregnancy. Most proceeded from public institutions, 37 (69%. The vaccination schedule of most children, 68 (61%, was incomplete. The main clinical indications for special immunobiologicals were prematurity and bronchopulmonary dysplasia. It was observed that 89% (n = 100 of preterm infants received the pneumococcal vaccine (Prevenar. For preterm infants who were at risk of developing serious events related to the tetravalent vaccine, it was elected the scheme Prevenar + DTPa + Hib. Simultaneous administration of meningococcal conjugate vaccines - C (MncC with Prevenar was indicated for candidates for cochlear implants. Conclusion: The integral care to the preterm newborn involves early immunization, that is, the one that starts in the neonatal unit, and requires the inclusion of special immunobiologicals, which should be criteriously recommended.

Technique for detecting a small magnitude loss of special nuclear material

International Nuclear Information System (INIS)

Pike, D.H.; Chernick, M.R.; Downing, D.J.

The detection of losses of special nuclear materials has been the subject of much research in recent years. The standard industry practice using ID/LEID will detect large magnitude losses. Time series techniques such as the Kalman Filter or CUSUM methods will detect small magnitude losses if they occur regularly over a sustained period of time. To date no technique has been proposed which adequately addresses the problem of detecting a small magnitude loss occurring in a single period. This paper proposes a method for detecting a small magnitude loss. The approach makes use of the influence function of Hempel. The influence function measures the effect of a single inventory difference on a group of statistics. An inventory difference for a period in which a loss occurs can be expected to produce an abnormality in the calculated statistics. This abnormality is measurable by the influence function. It is shown that a one period loss smaller in magnitude than the LEID can be detected using this approach

Comparison of East Asian winter monsoon indices

Directory of Open Access Journals (Sweden)

Gao Hui

2007-01-01

Full Text Available Four East Asian winter monsoon (EAWM indices are compared in this paper. In the research periods, all the indices show similar interannual and decadal-interdecadal variations, with predominant periods centering in 3–4 years, 6.5 years and 9–15 years, respectively. Besides, all the indices show remarkable weakening trends since the 1980s. The correlation coefficient of each two indices is positive with a significance level of 99%. Both the correlation analyses and the composites indicate that in stronger EAWM years, the Siberian high and the higher-level subtropical westerly jet are stronger, and the Aleutian low and the East Asia trough are deeper. This circulation pattern is favorable for much stronger northwesterly wind and lower air temperature in the subtropical regions of East Asia, while it is on the opposite in weaker EAWM years. Besides, EAWM can also exert a remarkable leading effect on the summer monsoon. After stronger (weaker EAWM, less (more summer precipitation is seen over the regions from the Yangtze River valley of China to southern Japan, while more (less from South China Sea to the tropical western Pacific.

Three dimensional periodic foundations for base seismic isolation

Yan, Y; Mo, Y L; Cheng, Z; Shi, Z; Menq, F; Tang, Y

2015-01-01

Based on the concept of phononic crystals, periodic foundations made of periodic materials are investigated in this paper. The periodic foundations can provide low frequency band gaps, which cover the main frequency ranges of seismic waves. Therefore, the periodic foundations are able to protect the upper structures during earthquake events. In this paper, the basic theory of three dimensional periodic foundations is studied and the finite element method was used to conduct the sensitivity study. A simplified three-dimensional periodic foundation with a superstructure was tested in the field and the feasibility of three dimensional periodic foundations was proved. The test results showed that the response of the upper structure with the three dimensional periodic foundation was reduced under excitation waves with the main frequency falling in the attenuation zones. The finite element analysis results are consistent with the experimental data, indicating that three dimensional periodic foundations are a feasible way of reducing seismic vibrations. (paper)

REGIONAL SPECIALIZATION AND INDUSTRIAL CONCENTRATION IN THAILAND, 1996-2005

Directory of Open Access Journals (Sweden)

Apisek Pansuwan

2009-06-01

Full Text Available This paper provides a descriptive analysis of the changes in the industrial and spatial concentration that occurred in Thailand from 1996 to 2005. Based on the data from the Department of Industrial Work of the Ministry of Industry and using the Hirschman-Herfindahl index of concentration, the geographical concentration of industries in the study regions was measured. The Hirschman-Herfindahl index has the useful property of being decomposable into sources of changes in the concentration. Moreover, location quotient was also used to measure the regional specialization of the manufacturing industries in Thailand. Results of the analysis indicated that from 1996 to 2005, the decrease in the spatial concentration of manufacturing as well as in the regional specialization in manufacturing in Thailand remained stable to a lesser extent. The results have also indicated that most factories continue to be concentrated in Bangkok and its neighboring areas. It can therefore be best argued that in the case of Thailand, the effect of its trade liberalization policy has been more powerful than its industrial decentralization policy.

Special frequencies and Lifshitz singularities in binary random harmonic chains

International Nuclear Information System (INIS)

Nieuwenhuizen, T.M.; Luck, J.M.; Canisius, J.; van Hemmen, J.L.; Ventevogel, W.J.

1986-01-01

The authors consider a one-dimensional chain of coupled harmonic oscillators; the mass of each atom is a random variable taking only two values (M or 1). They investigate the integrated density of states H(omega 2 ) near special frequencies: a given frequency omega/sub s/ with rational wavelength becomes special if the mass ratio M exceeds a certain critical value M/sub c/. They show that H has essential singularities of the types H/sub sg/∼ exp(-C 1 absolute value of omega 2 -omega/sub s/ 2 /sup 1/2/) or exp(-C 2 absolute value of omega 2 -omega/sub s/ 2 -1 ), according to the value of M and the sign of (omega 2 -omega/sub s/ 2 ). The Lifshitz singularity at the band edge is analyzed in the same way. In each case, the constant C 1 or C 2 is evaluated explicitly and compared with a vast amount of numerical work. All these exponential singularities are modulated by periodic amplitudes. The properties of the eigenfunctions with frequencies close to the special values are also discussed, and are illustrated by numerical data

Current status of biological indicators to detect and quantify previous exposures to radiation. Biological Indicators Working Group

Lushbaugh, C.; Eisele, G.; Burr, W. Jr.; Hubner, K.; Wachholz, B.

1991-01-01

Hematologic changes following whole-body exposure to gamma or x-ray radiation have been used to estimate dose. The usefulness of this biological indicator is limited because of the recovery of these cells with time, thus making it unsuitable for estimation of dose years after exposure. The same is true for spermatogenic indicators; recovery and restoration of sperm numbers and fertility makes this biological indicator impractical for assessing radiation dose decades after radiation exposure. As noted in the text of the report, immunological concepts are in a state of rapid development, and it is possible that improved methods for applying immunologic procedures as biological indicators of radiation may be developed in the future. However, at the time, immunological indicators are not useful, even in an early time period, for quantitating radiation dose after total-body irradiation. A semiquantitative effect is observable in the early phase after total-body irradiation over a period of days to weeks, but there is little data available to indicate whether any of the immunological parameters can be indicative of a dose when the test is applied several years after radiation exposure. More detailed information regarding immunological indicators for estimating irradiation dose has been summarized elsewhere (Wasserman 1986). There is good agreement that ionizing radiation causes biochemical changes in the body; however, attempts to apply these changes to provide a reliable biological dosimetry system have not been particularly successful. The status of this research has been summarized by Gerber (1986). One of the difficulties has been the problem of establishing clear dose-effect relationships in humans. The lack of specificity in the response for radiation is another problem

Kovacs, Tibor; Somlai, Janos; Szeiler, Gabor; Nemeth, Csaba; Tokonami, Shinji; Takahashi, Hiroyuki

2008-01-01

In this study a comparative integrating radon ( 222 Rn) and thoron ( 220 Rn) survey executed at underground workplaces are discussed. Two types of solid state nuclear track detectors (Radopot and Raduet) were applied for survey at four sites: a manganese mine, a bauxite mine, a tourist cave and a hospital cave. Several numbers of detecting points were chosen at each site and 1-1 Raduet and Radopot detector were placed at each point. Both detector types contains two polycarbonate (CR-39) foils in different holders in order to determinate the radon as well as the thoron levels. The detectors were changed in 30-60 days periods (approximately monthly) and the survey continued for a year. This study had two aims: 1) To gain information about the radon and thoron concentrations at the chosen places including the seasonal variations; 2) To compare the performance of the two types of detectors and check their response in the special circumstances indicates by these underground places. Concerning the first point the radon concentrations were found to be as the expected ones at the given underground places and were similar to our former measurements. In the case of thoron the results are very variable and significant part of the detectors provides no data or unrealistic data. Concerning the second point there was only a little difference (<10%) between the radon results provided by the two types of detectors. In the case of thoron the two detector types showed high inconsistency. The study suggests that both types of detectors are fit for the integrating radon measurement at these special circumstances but it cannot be stated the same for the thoron measurement. The reason of the unreliability of the thoron measurement could be the high humidity (especially in the caves), the high aerosol concentration (especially in the mines) and the air change rate variation. To find the reasons needs further study. (author)

Special relativity

International Nuclear Information System (INIS)

Taylor, J.G.

1975-01-01

It is stated that the early chapters review special relativity from an elementary mathematical viewpoint, and include discussion of recent experiments which set out to test Einstein's predictions. The theory of relativity is then reformulated in more sophisticated mathematical language to show its relation to electro-magnetism, and to lay the foundation for more general viewpoints. The final chapter discusses in simple terms where activity in the field is currently centred, and where future interest lies. Chapter headings include: the constant speed of light; measuring time and distance; the Lorentz transformation (relativity of simultaneity, space-time and causality); relativistic kinematics (including - the Dopper effect); relativistic dynamics (including - nuclear binding energy, particle creation, electrodynamics); the structure of special relativity (including - the Lorentz group, the rotation group, elementary particle scattering); extensions of special relativity.

Chakraborty, Sukumar; Obanor, Friday; Westecott, Rhyannyn; Abeywickrama, Krishanthi

2010-10-01

This article reports a lack of pathogenic specialization among Australian Fusarium graminearum and F. pseudograminearum causing crown rot (CR) of wheat using analysis of variance (ANOVA), principal component and biplot analysis, Kendall's coefficient of concordance (W), and κ statistics. Overall, F. pseudograminearum was more aggressive than F. graminearum, supporting earlier delineation of the crown-infecting group as a new species. Although significant wheat line-pathogen isolate interaction in ANOVA suggested putative specialization when seedlings of 60 wheat lines were inoculated with 4 pathogen isolates or 26 wheat lines were inoculated with 10 isolates, significant W and κ showed agreement in rank order of wheat lines, indicating a lack of specialization. The first principal component representing nondifferential aggressiveness explained a large part (up to 65%) of the variation in CR severity. The differential components were small and more pronounced in seedlings than in adult plants. By maximizing variance on the first two principal components, biplots were useful for highlighting the association between isolates and wheat lines. A key finding of this work is that a range of analytical tools are needed to explore pathogenic specialization, and a statistically significant interaction in an ANOVA cannot be taken as conclusive evidence of specialization. With no highly resistant wheat cultivars, Fusarium isolates mostly differ in aggressiveness; however, specialization may appear as more resistant cultivars become widespread.

2015-03-01

Keratins are the most abundant proteins and are characteristic findings in many epithelial pathologies, making it a diagnostically important marker, both histopathologically and immunohistochemically. Since, immunohistochemistry is an expensive diagnostic tool, special stains to detect the degree of keratinization could serve as a faster and economic option. The aim of the present study was to compare the efficacy of special stains for keratin with standard hematoxylin and eosin stain (H and E). Objectives include: (i) To subject the diagnosed cases of keratin disorders to the selected special stains: Ayoub-shklar method, Dane-Herman method, Alcian blue -periodic acid Schiff 's (PAS), rapid papanicolaou (PAP) and Gram's stain. (ii) To compare the staining specificity and staining intensity of special stains with respect to routine hematoxylin and eosin (H and E) stain. (iii) To compare the efficacy of special stains to routine H and E stain in identification of the type of keratin present in the selected cases. A total of 80 cases of known pathology for keratin were retrieved from the department archive, which included 10 each of normal gingiva, hyperkeratosis, squamous papilloma, verrucous hyperplasia, verrucous carcinoma, well-differentiated squamous cell carcinoma, orthokeratinized odontogenic cyst and keratocystic odontogenic tumors. Six sections of 4 µ each from the paraffin blocks were made, stained with H and E and the special stains and these were evaluated by 2 pathologists based on the modified scoring criteria from Rahma Al-Maaini and Philip Bryant 2008. The results were tabulated using Chi square and kappa statistics. The statistical values for identification of the type of keratinization was insignificant showing that ortho and parakeratinized epithelia could be correctly identified by both H and E as well as all the special stains. Furthermore, all the special stains showed a positive result and statistical significance (P < 0.001) with respect to

This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance of Global Navigation Satellite System (GNSS). This index is based in the Along Arc TEC Rate (AATR) and can be easily computed from dual-frequency GNSS measurements. The AATR indicator has been assessed over more than one Solar Cycle (2002-2017) involving about 140 receivers distributed world-wide. Results show that it is well correlated with the ionospheric activity and, unlike other global indicators linked to the geomagnetic activity (i.e. DST or Ap), it is sensitive to the regional behaviour of the ionosphere and identifies specific effects on GNSS users. Moreover, from a devoted analysis of different Satellite Based Augmentation System (SBAS) performances in different ionospheric conditions, it follows that the AATR indicator is a very suitable mean to reveal whether SBAS service availability anomalies are linked to the ionosphere. On this account, the AATR indicator has been selected as the metric to characterise the ionosphere operational conditions in the frame of the European Space Agency activities on the European Geostationary Navigation Overlay System (EGNOS). The AATR index has been adopted as a standard tool by the International Civil Aviation Organization (ICAO) for joint ionospheric studies in SBAS. In this work we explain how the AATR is computed, paying special attention to the cycle-slip detection, which is one of the key issues in the AATR computation, not fully addressed in other indicators such as the Rate Of change of the TEC Index (ROTI). After this explanation we present some of the main conclusions about the ionospheric activity that can extracted from the AATR values during the above mentioned long-term study. These conclusions are: (a) the different spatial correlation related with the MOdified DIP (MODIP) which allows to clearly separate high, mid and low latitude regions, (b) the large spatial correlation in mid

Desertification, resilience, and re-greening in the African Sahel - a matter of the observation period?

Science.gov (United States)

Kusserow, Hannelore

2017-12-01

Since the turn of the millennium various scientific publications have been discussing a re-greening of the Sahel after the 1980s drought mainly based on coarse-resolution satellite data. However, the author's own field studies suggest that the situation is far more complex and that both paradigms, the encroaching Sahara and the re-greening Sahel, need to be questioned.This paper discusses the concepts of desertification, resilience, and re-greening by addressing four main aspects: (i) the relevance of edaphic factors for a vegetation re-greening, (ii-iii) the importance of the selected observation period in the debate on Sahel greening or browning, and (iv) modifications in the vegetation pattern as possible indicators of ecosystem changes (shift from originally diffuse to contracted vegetation patterns).The data referred to in this paper cover a time period of more than 150 years and include the author's own research results from the early 1980s until today. A special emphasis, apart from fieldwork data and remote sensing data, is laid on the historical documents.The key findings summarised at the end show the following: (i) vegetation recovery predominantly depends on soil types; (ii) when discussing Sahel greening vs. Sahel browning, the majority of research papers only focus on post-drought conditions. Taking pre-drought conditions (before the 1980s) into account, however, is essential to fully understand the situation. Botanical investigations and remote-sensing-based time series clearly show a substantial decline in woody species diversity and cover density compared to pre-drought conditions; (iii) the self-organised patchiness of vegetation is considered to be an important indicator of ecosystem changes.

In our therapeutic activity the non-conventional indications represent 5-10% relative to the indisputable indications which the hyperthyroidism in the second half of the life and the differential thyroid cancers are. In this paper our experience since 1966 is revised and confronted with the data of international literature. In the last almost 40 years we have treated 178 hyperthyroidism of which 17 were youngsters between 16 and 20 years old, 17 multi-nodular euthyroid goiters (MEG), 85 advanced cardiopathies and 8 Cordarone cardiopathies. The indications are precise: relapses after ATS or surgery in young subjects, counter-indications or surgery refusal for the MEGs and cardiologic indications. The long term surveillance was managed by an adequate code. Immediate morbidity is null. The efficiency is high in the hyperthyroidism treatment. The hypothyroidism is diagnosed and early treated. The reduction of the MEG mass is significant. An objective amelioration of the heart state was obtained (23%). The evaluation of the preventive effect of induced hyperthyroidism by Cordarone is underway. In conclusion, the enlargement of indications concerns mainly the hyperthyroidism in young subjects. In order to avoid carcinogenic risks we excluded the children under 16 years, excepting for special situations. This extension to the procreation age imposes a rigorous application of contraception and radiation protection instructions and needs a prolonged evaluation of results

Special protective concretes

International Nuclear Information System (INIS)

Bouniol, P.

2001-01-01

Concrete is the most convenient material when large-scale radiation protection is needed. Thus, special concretes for nuclear purposes are used in various facilities like reactors, reprocessing centers, storage sites, accelerators, hospitals with nuclear medicine equipment, food ionization centers etc.. The recent advances made in civil engineering for the improvement of concrete durability and compactness are for a large part transposable to protection concretes. This article presents the basic knowledge about protection concretes with the associated typological and technological aspects. A large part is devoted to the intrinsic properties of concretes and to their behaviour in irradiation and temperature conditions: 1 - definition and field of application of special protective concretes; 2 - evolution of concepts and technologies (durability of structures, techniques of formulation, new additives, market evolution); 3 - design of protective structures (preliminary study, radiation characteristics, thermal constraints, damping and dimensioning, mechanical criteria); 4 - formulation of special concretes (general principles, granulates, hydraulic binders, pulverulent additives, water/cement ratio, reference composition of some special concretes); 5 - properties of special concretes (damping and thermo-mechanical properties); 6 - induced-irradiation and temperature phenomena (activation, radiolysis, mineralogical transformations, drying, shrinking, creep, corrosion of reinforcement).

Up-grading a 4.7-cm-period plane electromagnetic undulator

International Nuclear Information System (INIS)

Bogachenkov, V.A.; Kondratyev, K.V.; Papadichev, V.A.

1999-01-01

Electromagnetic undulators have a number of advantages over permanent-magnet undulators. They are less expensive to fabricate and their field is easily regulated by changing the current, without requiring a complex and expensive precision system for changing the undulator gap. Their main weaknesses are that they require a large power supply and that the field is limited due to yoke saturation mainly because of large axial stray fluxes, particularly in simple constructions. Modernization of a 4.7-cm-period, 20-period long plane electromagnetic undulator of simple design is described. Samarium-cobalt permanent magnets were used to increase the field and decrease power consumption. They were placed between adjacent rings (with opposite sign of field) and while increasing the working field they decreased saturation of the iron yokes. Small lateral displacements of permanent magnets were used to equalize field amplitudes in half periods of the undulator with 0.1% accuracy. Matched input and output to and from the undulator, respectively, were formed by means of auxiliary permanent magnets and special magnetic screens

Rogovchenko, Svitlana P.; Rogovchenko, Yuri V.

2009-01-01

We address the effect of periodic environmental fluctuations on the Pearl-Verhulst model in population dynamics and clarify several important issues very actively discussed in the recent papers by Lakshmi [Lakshmi BS. Oscillating population models. Chaos Solitons and Fractals 2003;16:183-6; Lakshmi BS. Population models with time dependent parameters. Chaos Solitons and Fractals 2005;26:719-21], Leach and Andriopoulos [Leach PGL, Andriopoulos K. An oscillatory population model. Chaos Solitons and Fractals 2004;22:1183-8], Swart and Murrell [Swart JH, Murrell HC. An oscillatory model revisited. Chaos Solitons and Fractals 2007;32:1325-7]. Firstly, we review general results regarding existence and properties of periodic solutions and examine existence of a unique positive asymptotically stable periodic solution of a non-autonomous logistic differential equation when r(t)>0. Proceeding to the case where r(t) is allowed to take on negative values, we consider a modified Pearl-Verhulst equation because, as emphasized by Hallam and Clark [Hallam TG, Clark CE. Non-autonomous logistic equations as models of populations in deteriorating environment. J Theor Biol 1981;93:303-11], use of the classic one leads to paradoxical biological conclusions. For a modified logistic equation with ω-periodic coefficients, we establish existence of a unique asymptotically stable positive periodic solution with the same period. Special attention is paid to important cases where time average of the intrinsic growth rate is non-positive. Results of computer simulation demonstrating advantages of a modified equation for modeling periodic environmental fluctuations are presented.

Sports Specialization in Young Athletes

Science.gov (United States)

Jayanthi, Neeru; Pinkham, Courtney; Dugas, Lara; Patrick, Brittany; LaBella, Cynthia

2013-01-01

Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. Evidence Acquisition: PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. Results: For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Conclusion: Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

Full Text Available Analyzed the structure and content of the competition period in mini-football. It was determined that the structure of the competition period consists of 4 competitive mesocycles. In each mesocycle includes various types of micro-cycles (competitive, cross-game and rehabilitation. Reflects the ratio of specific and non-specific (general preparations means training work. So in the competitive period for competitive mesocycles general preparations exercises ranged from 38.3 to 42.4%, special-preparation - from 29.9 to 32.6%, competitive - from 20.9 to 23.3%. The intensity of the training load in intergame microcycles less than competitive. This corresponds to the strategy of building the training process in the competitive period. During the competition period the ratio of the training load was: aerobic focus - 49.2%, mixed - 46.1%, anaerobic alactate - 2.4%, anaerobic glycolytic - 2.3%. Defines the scope and focus of the training load: longer the aerobic work, then - mixed, anaerobic- alactate and anaerobic-glycolytic. The comparative characteristics of the intensity of the training load in competitive and intergame microcycles.

Rotation periods of 12253 stars in the Kepler field. The periods are determined by the brightness variations, from star spots or active regions, in the light curves of the white light photometry obtained by the Kepler spacecraft. The median absolute deviation from the median (MAD) of the periods...... shows the scatter of periods for each star, over 6 or more (out of 8 analyzed) Kepler quarters. The g-r color index, E(B-V), radius, surface gravity, and effective temperature are from the Kepler Input Catalog (KIC). Column 9 (TF) indicates whether or not the msMAP data for a given star satisfies...... the selection criteria described in section 2. Of these, there are 86 stars with periods from the msMAP data that differ from the period derived from the PDCMAP data by more than one frequency resolution element (1/90d-1). For these stars the msMAP periods are therefore given in column 10 as a none-zero value...

IEP Use by General and Special Education Teachers

2014-04-01

Full Text Available The role of general and special educators in implementing the Individualized Education Program (IEP is critical. This study investigated the perceptions of those teachers on when they read the IEP, how they measure attainment of IEP goals and objectives, and the IEPs usefulness in instructional planning. Four hundred twenty-six teachers from suburban school districts in central New Jersey were respondents. Results indicated that the majority of general and special education teachers are reading their students’ IEPs in a fairly timely manner and that they find them moderately useful in planning instruction. Results also suggested that teachers relied heavily on grades to document attainment of IEP goals and that teachers felt that the IEPs themselves could be improved if they were shorter with student-specific, critical information that was more relevant to classroom instruction.

The dental specialties related articles published in Medical Journal Armed Forces India from 2000 to 2014 over a 15-year period.

There is a paucity of information about the dental specialties related articles published in the Medical Journal Armed Forces India (MJAFI). This study aimed to audit the dental specialities related articles published in MJAFI from 2000 to 2014 over a 15-year period. Bibliometric analysis of sixty issues of MJAFI from 2000 to 2014 were performed using web-based search. The articles published were analyzed for type of article and topic of individual dental specialities. The articles published were also evaluated to identify whether the study was an Armed Forces Medical Research Committee Project or funded research project or not. Out of the total 118 published articles related to dental specialities, original articles (55) and case reports (49) contribute the major share. The highest number of dental specialities related articles was published in 2009 with 16, followed by 2010 with 13 and 2011 with 11 and the least published year was 2013 with 3 articles. Regarding the relationship with dental specialities, the maximum number of published articles were related to oral medicine and radiology (56) followed by oral and maxillofacial surgery (49), orthodontics (23) and prosthodontics (17). Among the articles published in MJAFI, maxillofacial injuries (11) followed by orthodontic treatment (8) and craniofacial deformities (8) form the major attraction of the contributors. Among the 118 dental speciality articles, there were only 4 Armed Forces Medical Research Committee Project articles and 19 funded research project articles. An equal distribution of articles related to clinical dentistry and nonclinical dentistry is maintained for the MJAFI from 2000 to 2014 over a 15-year period.

Full Text Available A teacher’s willingness to accept inclusion has been identified as an indicator of the quality of experience that a student with special needs will have in the classroom The purpose of this exploratory study was twofold: (1 to describe the overall perceptions of working with students with special needs and (2 to determine how teachers in Louisiana are currently working with students with special needs.  A total of 152 teachers attended the Louisiana agricultural education teacher’s summer conference with 43% completing a three part survey instrument.  Data analysis indicated that teachers are confident in their ability to work with students with special needs and they agree that they can incorporate various areas of inclusion within their programs. However, they disagreed that they have received adequate in-service opportunities related to special education.  Regarding educational strategies, teachers in this study identified all of the given inclusion strategies as being used regularly in their programs with the exception of tutoring after school.  They also identified these educational practices as being highly effective within their programs. Due to the exploratory nature of this study, additional research is recommended to further investigate the in-service and training needs of teachers in Louisiana.

The regulatory framework of special medical group students' physical education: identifying the problem.

Directory of Open Access Journals (Sweden)

Mazur Valerij Anatol'evich

2011-09-01

Full Text Available The question of regulatory framework for special medical group students' physical education, and their physical condition in particular is elaborated. It is found that in the current program the identified question is missing, although the assessment of individual performance standards for the physical condition of the students was envisaged in the programs of 1977 and 1982. The need for such an assessment is indicated by the large number of Ukrainian and foreign pediatricians and specialists in therapeutic physical culture. At the same time the standards for assessing these indicators are not developed. It complicates the formation of positive motivation of students to regular classes, and does not promote their self-confidence, capabilities and effectiveness of monitoring the effectiveness of exercise in various forms. The findings suggest the need to define the optimal composition of the bulk of tests and functional tests to assess the physical condition of special medical group students with various diseases and to develop appropriate indicators for their evaluation standards.

Acoustic nonlinear periodic waves in pair-ion plasmas

Mahmood, Shahzad; Kaladze, Tamaz; Ur-Rehman, Hafeez

2013-09-01

Electrostatic acoustic nonlinear periodic (cnoidal) waves and solitons are investigated in unmagnetized pair-ion plasmas consisting of same mass and oppositely charged ion species with different temperatures. Using reductive perturbation method and appropriate boundary conditions, the Korteweg-de Vries (KdV) equation is derived. The analytical solutions of both cnoidal wave and soliton solutions are discussed in detail. The phase plane plots of cnoidal and soliton structures are shown. It is found that both compressive and rarefactive cnoidal wave and soliton structures are formed depending on the temperature ratio of positive and negative ions in pair-ion plasmas. In the special case, it is revealed that the amplitude of soliton may become larger than it is allowed by the nonlinear stationary wave theory which is equal to the quantum tunneling by particle through a potential barrier effect. The serious flaws in the earlier published results by Yadav et al., [PRE 52, 3045 (1995)] and Chawla and Misra [Phys. Plasmas 17, 102315 (2010)] of studying ion acoustic nonlinear periodic waves are also pointed out.

High-technology exports of EEC countries: Persistence and diversity of specialization patterns

Papagni, E.

1992-01-01

This analysis of the persistence and diversity of specialization patterns in EEC high technology exports is based on a package of products selected from the Eurostat database, COMEXT. High technology goods are considered as an innovative output indicator. A test of hypotheses of hysteresis and diversity of trade patterns at a national level is performed to verify some claims made by the 'evolutionary' theory of innovation and trade. The three-mode principal component analysis carried out confirms the persistence of specialization patterns of each EEC country in high technology exports, and highlights their sharp differences

Population structure of the Classic period Maya.

Scherer, Andrew K

2007-03-01

This study examines the population structure of Classic period (A.D. 250-900) Maya populations through analysis of odontometric variation of 827 skeletons from 12 archaeological sites in Mexico, Guatemala, Belize, and Honduras. The hypothesis that isolation by distance characterized Classic period Maya population structure is tested using Relethford and Blangero's (Hum Biol 62 (1990) 5-25) approach to R matrix analysis for quantitative traits. These results provide important biological data for understanding ancient Maya population history, particularly the effects of the competing Tikal and Calakmul hegemonies on patterns of lowland Maya site interaction. An overall F(ST) of 0.018 is found for the Maya area, indicating little among-group variation for the Classic Maya sites tested. Principal coordinates plots derived from the R matrix analysis show little regional patterning in the data, though the geographic outliers of Kaminaljuyu and a pooled Pacific Coast sample did not cluster with the lowland Maya sites. Mantel tests comparing the biological distance matrix to a geographic distance matrix found no association between genetic and geographic distance. In the Relethford-Blangero analysis, most sites possess negative or near-zero residuals, indicating minimal extraregional gene flow. The exceptions were Barton Ramie, Kaminaljuyu, and Seibal. A scaled R matrix analysis clarifies that genetic drift is a consideration for understanding Classic Maya population structure. All results indicate that isolation by distance does not describe Classic period Maya population structure. (c) 2006 Wiley-Liss, Inc.

We report on the high frequency of pleural effusions in the immediate postpartum period. Forty-four out of 45 women who examined within 24-48 h after delivery showed evidence of pleural fluid. Under these circumstances, this pleural abnormality should not be considered an indicator of serious cardiopulmonary disease. (orig.) [de

A Smaller Percent of Hispanic Children Have Special Health Care Needs: Is that Possible?

Waldman, H Barry; Wong, Allen; Rojas, Jorge E; Perlman, Steven P

The results from latest study of children with special health care needs indicate at the national and state levels that (except for Asian children) the proportion of Hispanic children with special needs is less than for other child populations. A review of a series of associated factors raises questions of the validity of these general national and state findings. The significant projected increases in the Hispanic population during the next decades points to the necessity of reconsidering the recent survey findings in light of what could be continued increases in the numbers of youngsters with special health care needs and the evolving family cultural adaptation, education and employment opportunities.

Schom, C.; Engelke, W.; Kopka, L.; Fischer, U.; Grabbe, E.

1996-01-01

Based on case reports, common indications for dental computed tomography are demonstrated and typical findings are analysed. From a group of 110 patients who had a reformatted computed tomography of the maxilla and mandibula, 10 typical cases were chosen as examples and are presented with a detailed description of the findings. The most important indication was the analysis of the morphology of the alveolar ridge needed in presurgical planning for osseointegrated implants as well as in special cases of postsurgical control. Apart from implantology, the method could be used in cases of mandibular cysts and bony destructions. In conclusion, dental computed tomography has become established mainly in implantology. It can provide valuable results in cases where a demonstration of the bone in all dimensions and free of overlappings and distortions is needed. (orig.) [de

The coolant channel in Pressurized Heavy Water Reactors is a pressure boundary component and is very important for reactor performance and reactor safety. Monitoring the condition of the pressure tube of each coolant channel on a periodic basis is very important. In-Service Inspection (ISI) of the coolant channels in water filled condition is done regularly for 220 MWe PHWR. For the same purpose BARC Channel Inspection System is developed for 540 MWe PHWR also. Special Sealing Plug has been developed to facilitate the channel inspection (in water filled condition) with all necessary safety features at par with normal sealing plug. Special Sealing Plug provides a 50 mm through hole for passage of drive tube of Inspection Head maintaining integrity of PHT. Lot of challenges were faced for developing the Special Sealing Plug and its associated tools. It was a first of its kind design. First ISI of TAPS-4 was conducted successfully using this plug along with associated tools in November 2011. This development has provided immense help to NPCIL in life management of 540 MWe PHWR coolant channels. (author)

Full Text Available In line with the change of the society attitudes towards persons with disabilities there is increased interest in examining the atitudes twards them. Because of the role in the treatment, education and inclusion of such persons in wider social community, the attitudes of the students of special education become especially relevant. The aim of the research was to determine the attitudes of the future special educators towards persons with disabilities, the level of discomfort they feel in interaction with them, as well as the frequency of fontacts of students of special education with such persons. 103 students of the first cycle of the study program Special Education at the Faculty of Medicine in Foča. In the research we used the Scale for evaluating attitudes towards persons with disabilities, the Scale of interactions with persons with disabilities, and the Scale for assessing the frequency of contacts with persons with disabilities. Special education students on average have mildly positive attitudes towards persons with disabilities and feel somewhat comfortable in direct interactions with them, but the contacts with them are relatively rare. Among the examined variables significant relation was found between the year of study of the examinees and the frequency of their contacts with persons with disabilities. The obtained results indicate the need for a more significant shift of focus from medical to a social model of disability in the education of students of special education.

Quality indicator collection and feedback improves stroke care. We sought to determine whether quality improvement training plus indicator feedback was more effective than indicator feedback alone in improving inpatient stroke indicators. We conducted a cluster-randomised quality improvement trial, randomising hospitals to quality improvement training plus indicator feedback versus indicator feedback alone to improve deep vein thrombosis (DVT) prophylaxis and dysphagia screening. Intervention sites received collaborative-based quality improvement training, external facilitation and indicator feedback. Control sites received only indicator feedback. We compared indicators pre-implementation (pre-I) to active implementation (active-I) and post-implementation (post-I) periods. We constructed mixed-effect logistic models of the two indicators with a random intercept for hospital effect, adjusting for patient, time, intervention and hospital variables. Patients at intervention sites (1147 admissions), had similar race, gender and National Institutes of Health Stroke Scale scores to control sites (1017 admissions). DVT prophylaxis improved more in intervention sites during active-I period (ratio of ORs 4.90, pimproved similarly in both groups during active-I, but control sites improved more in post-I period (ratio of ORs 0.67, p=0.04). In logistic models, the intervention was independently positively associated with DVT performance during active-I period, and negatively associated with dysphagia performance post-I period. Quality improvement training was associated with early DVT improvement, but the effect was not sustained over time and was not seen with dysphagia screening. External quality improvement programmes may quickly boost performance but their effect may vary by indicator and may not sustain over time. Published by the BMJ Publishing Group Limited.

In the article, questions and tasks of determination of power and the moment on a shaft of special asynchronous electric drives are considered. Use of special asynchronous electric drives in mechanical engineering and other industries is relevant. The considered types of electric drives possess the improved mass-dimensional indicators in comparison with singleengine systems. Also these types of electric drives have constructive advantages; the improved characteristics allow one to realize the technological process. But creation and design of new electric drives demands adjustment of existing or development of new methods and approaches of calculation of parameters. Determination of power and the moment on a shaft of special asynchronous electric drives is the main objective during design of electric drives. This task has been solved based on a method of electromechanical transformation of energy.

Operational safety performance indicator system at the Dukovany Nuclear Power Plant - Experience with indicator aggregation

International Nuclear Information System (INIS)

Mandula, J.

2001-01-01

The operational safety performance indicators serve as an important tool of performance monitoring and management at the Dukovany NPP. A software-supported system has been developed, which has included: data collection, central data storage, graphic output production and periodical report generation. Analyses of performance indicator trends together with evaluation in respect of annually updated target values and acceptance criteria are used for operational safety reviews forming an integral part of continual self-assessment process. This contribution has been focused on experience obtained during development of the operational safety assessment model using indicator aggregation. It summarises problems that had to be paid specific attention in the development process. Thanks to their solution, the model has become a synoptic monitor and a useful tool for operational safety assessment. (author)

Comparison of UTCI to selected thermal indices.

Over the past century more than 100 indices have been developed and used to assess bioclimatic conditions for human beings. The majority of these indices are used sporadically or for specific purposes. Some are based on generalized results of measurements (wind chill, cooling power, wet bulb temperature) and some on the empirically observed reactions of the human body to thermal stress (physiological strain, effective temperature). Those indices that are based on human heat balance considerations are referred to as "rational indices". Several simple human heat balance models are known and are used in research and practice. This paper presents a comparative analysis of the newly developed Universal Thermal Climate Index (UTCI), and some of the more prevalent thermal indices. The analysis is based on three groups of data: global data-set, synoptic datasets from Europe, and local scale data from special measurement campaigns of COST Action 730. We found the present indices to express bioclimatic conditions reasonably only under specific meteorological situations, while the UTCI represents specific climates, weather, and locations much better. Furthermore, similar to the human body, the UTCI is very sensitive to changes in ambient stimuli: temperature, solar radiation, wind and humidity. UTCI depicts temporal variability of thermal conditions better than other indices. The UTCI scale is able to express even slight differences in the intensity of meteorological stimuli.

The Specialized school in time of inclusion

Roseli Albino dos Santos

2014-04-01

Full Text Available This study has the objective to investigate the meanings about school inclusion and disability, produced by a group of professionals engaged in a specialized school located in a city in the state of São Paulo. The metodology used was semi-structured and structured interviews with the director of the institution, two pedagogical coordinators and five teachers. Data were subjected to a descriptive-interpretative analysis. The results indicated that professionals attribute the responsibility for self development, only to students with intellectual disabilities . The emphasis of the speeches falls on the inability of the student and the immutability of disability. It is observed that the narratives do not reveal critical positioning of professional educational processes involving this population. The professionals who work in specialized institution still have a conception of disability based on the inability of the student and, despite defending the right of these students to school inclusion, these professionals still manifest fear of what they will find outside the walls of the institution, revealing attitudes and overprotection ignorance of the role of specialized institution in times of inclusion. We conclude that the conceptions about intellectual disability and inclusive education presented by professionals can contribute much more to the reiteration of school exclusion, historically focused on this population than for its actual inclusion in the school system of education.

A coherent oscillation of approximately 88 s period and 0.m005 amplitude was detected during the decline stage at the end of the long eruption of VW Hyi in December 1975. The period changed erratically between 86 and 90 s during eight nights. There are indications that the amplitude depends on the phase of the orbital revolution. The new period favours models in which such oscillations are caused by the orbital motion of inhomogeneities in the disc. (orig.) [de

Precipitation Indices Low Countries

Since 1995, KNMI published a series of books(1), presenting an annual reconstruction of weather and climate in the Low Countries, covering the period AD 763-present, or roughly, the last millennium. The reconstructions are based on the interpretation of documentary sources predominantly and comparison with other proxies and instrumental observations. The series also comprises a number of classifications. Amongst them annual classifications for winter and summer temperature and for winter and summer dryness-wetness. The classification of temperature have been reworked into peer reviewed (2) series (AD 1000-present) of seasonal temperatures and temperature indices, the so called LCT (Low Countries Temperature) series, now incorporated in the Millennium databases. Recently we started a study to convert the dryness-wetness classifications into a series of precipitation; the so called LCP (Low Countries Precipitation) series. A brief outline is given here of the applied methodology and preliminary results. The WMO definition for meteorological drought has been followed being that a period is called wet respectively dry when the amount of precipitation is considerable more respectively less than usual (normal). To gain a more quantitative insight for four locations, geographically spread over the Low Countries area (De Bilt, Vlissingen, Maastricht and Uccle), we analysed the statistics of daily precipitation series, covering the period 1900-present. This brought us to the following definition, valid for the Low Countries: A period is considered as (very) dry respectively (very) wet if over a continuous period of at least 60 days (~two months) cq 90 days (~three months) on at least two out of the four locations 50% less resp. 50% more than the normal amount for the location (based on the 1961-1990 normal period) has been measured. This results into the following classification into five drought classes hat could be applied to non instrumental observations: Very wet period

Education policies for Special Education in Brazil: a brief historical background

Full Text Available The present paper delivers an analysis and a systematization of the Brazilian legislation (from the nineteenth century to the year 2009 regarding the education of disabled people, as well as their rights and the services meant to support them. This research, which is based on collected data from relevant literature and documents, reviews the historical process of the trajectory of the Special Education in Brazil. The study indicates that educational policies in Brazil have identified the Special Education students differently over time. The teaching of students with disabilities or who failed to adapt themselves to regular education was offered separately from the common education. Due to the advancements on studies and research in the fields of Education and Human Rights, educational laws and practices began to change, which prompted the need of a reorganization of both the common schools and the special schools.

Specialization in and within sexual offending in England and Wales.

Science.gov (United States)

Howard, Philip D; Barnett, Georgia D; Mann, Ruth E

2014-06-01

Existing evidence suggests that offenders tend not to specialize in sexual offending in general but that there is some specialization in particular types of sexual offending. This study examined the sexual histories and reoffending of a large, national data set of offenders convicted of a sexual offense and managed in England and Wales by the National Offender Management Service (N = 14,804). The study found that specialization in sexual offending compared to nonsexual offending was most evident for offenders with convictions for accessing indecent images. We also found considerable evidence of specialization within sexual offending, most notably for noncontact offenders, especially again indecent images offenders. Crossover between sexual offense types was very rare for those with contact adult offenses and for noncontact offenders although those with child contact offenses sometimes crossed over to indecent images reoffending. If specialization within sexual offending exists, the use of single risk assessment instruments to predict all types of sexual recidivism may be less effective than previously assumed. A comparison of different prediction models indicated that some items presently used in one-size-fits-all risk tools to predict any sexual reoffending only effectively predict certain subtypes of sexual offending. Statistically there appear to be some potential benefits to creating specialist risk predictors for different subtypes of offending, but further work is needed to justify the implementation demands that would be caused by abandoning one-size-fits-all tools.

Canadian environmental sustainability indicators 2006

International Nuclear Information System (INIS)

2006-01-01

In 2004, the Canadian government committed to reporting annual national indicators of air quality, greenhouse gas (GHG) emissions and freshwater quality in order to provide Canadians with more regular and consistent information on the state of the environment and how it is linked with human activities. The national air quality indicators in this report focused on human exposure to ground-level ozone and fine particulate matter (PM 2.5 ). The report showed that from 1990 to 2004, the ozone indicator showed year-to-year variability, with an averaged increase of 0.9 per cent per year. Stations in southern Ontario reported the highest levels of ozone and PM 2.5 in the country in 2004. There was no discernible upward or downward trend in PM 2.5 levels at the national level for the 2000 to 2004 period, and GHG emissions rose 27 per cent from 1990 to 2004. In 2004, emissions were 35 per cent above the target to which Canada committed under the Kyoto Protocol. However, while total emissions rose, emissions per unit of gross domestic product (GDP) fell by 14 per cent from 1990 to 2004. GHG emissions also grew faster than the Canadian population, resulting in a 10 per cent rise in emissions per person. The freshwater quality indicator presented in this report covered the period from 2002 to 2004, and focused on the ability of Canada's surface waters to support aquatic life. For the 340 sites selected across southern Canada, water quality was rated as good or excellent at 44 per cent of sites, fair at 34 per cent of sites, and marginal or poor at 22 per cent of sites. The report included a chapter which attempted to integrate the indicators with other environmental impacts, measures of economic performance, and indices of social progress to improve the ability of the report to influence decision-making that fully accounts for environmental sustainability. 63 refs., 18 figs

Vakhtina, Elena; Wosnitza, Jan Henrik

2015-01-01

In this investigation, we examine the univariate as well as the multivariate capabilities of the log-periodic [super-exponential] power law (LPPL) for the prediction of bank runs. The research is built upon daily CDS spreads of 40 international banks for the period from June 2007 to March 2010, i.e. at the heart of the global financial crisis. For this time period, 20 of the financial institutions received federal bailouts and are labeled as defaults while the remaining institutions are categorized as non-defaults. The employed multivariate pattern recognition approach represents a modification of the CORA3 algorithm. The approach is found to be robust regardless of reasonable changes of its inputs. Despite the fact that distinct alarm indices for banks do not clearly demonstrate predictive capabilities of the LPPL, the synchronized alarm indices confirm the multivariate discriminative power of LPPL patterns in CDS spread developments acknowledged by bootstrap intervals with 70% confidence level.

Full Text Available In the present article, an attempt was made to assess the sustainability of agricultural holdings with diff erent directions of production. Agricultural holdings in the Podlaskie voivodeship registered in the FADN system in 2011–2012 were investigated. Assessment accounted for agroecological indicators (share of permanent grasslands, share of cereals in crops, soil coverage with vegetation, stock density and economic indicators (profi tableness of land and labor. Analysis was conducted according to a classifi cation into agricultural holding types: fi eldcrops, dairy cattle, and granivores. Fieldcrop and granivore holdings achieved more favourable environmental sustainability indicators. Holdings specializing in dairy cattle breeding posed a threat to the natural environment, mainly due to their excessive stock density. Economic sustainability assessment showed that granivore holdings were assessed most favorably. In these holdings, holding income per full-time worker was 37% greater than in fi eldcrop holdings and 57% greater than in dairy cattle holdings.

Dynamical groups of a particle in a periodic potential

Solving the Schroedinger non-relativistic equation of a particle moving under the influence of the potential V(θ) = ω(1 - cosθ) leads to us to the standard Mathieu equation.

With an approximation we study two important limiting cases, a simple quantum rotator and one-dimensional linear oscillator. We show the dynamical groups of these special, and a further study of the real problem connects us an Euclidean group of 2D. An IRR of matrix elements give us the energy levels.

Full Text Available The paper considers the problem of analysis and optimization of rod systems subjected to combined static and periodic pulse load. As a result of the study the analysis method was developed based on traditional approach to solving homogeneous matrix equations of state and a special algorithm for developing a particular solution. The influence of pulse parameters variations on stress-strain state of a rod system was analyzed. Algorithms for rod systems optimization were developed basing on strength recalculation and statement and solution of optimization problem as a problem of nonlinear mathematical programming. Recommendations are developed for efficient organization of process for optimization of rod systems under static and periodic pulse load.

Stability of periodic steady-state solutions to a non-isentropic Euler-Poisson system

Science.gov (United States)

Liu, Cunming; Peng, Yue-Jun

2017-06-01

We study the stability of periodic smooth solutions near non-constant steady-states for a non-isentropic Euler-Poisson system without temperature damping term. The system arises in the theory of semiconductors for which the doping profile is a given smooth function. In this stability problem, there are no special restrictions on the size of the doping profile, but only on the size of the perturbation. We prove that small perturbations of periodic steady-states are exponentially stable for large time. For this purpose, we introduce new variables and choose a non-diagonal symmetrizer of the full Euler equations to recover dissipation estimates. This also allows to make the proof of the stability result very simple and concise.

The Arctic is an interconnected and environmentally sensitive system of ice, ocean, land, atmosphere, ecosystems, and people. From local to pan-Arctic scales, the area has already undergone major changes in physical and societal systems and will continue at a pace that is greater than twice the global average. Key Arctic indicators can quantify these changes. Indicators serve as the bridge between complex information and policy makers, stakeholders, and the general public, revealing trends and information people need to make important socioeconomic decisions. This presentation evaluates and compiles more than 70 physical, biological, societal and economic indicators into an approachable summary that defines the changing Arctic. We divided indicators into "existing," "in development," "possible," and "aspirational". In preparing a paper on Arctic Indicators for a special issue of the journal Climatic Change, our group established a set of selection criteria to identify indicators to specifically guide decision-makers in their responses to climate change. A goal of the analysis is to select a manageable composite list of recommended indicators based on sustained, reliable data sources with known user communities. The selected list is also based on the development of a conceptual model that identifies components and processes critical to our understanding of the Arctic region. This list of key indicators is designed to inform the plans and priorities of multiple groups such as the U.S. Global Change Research Program (USGCRP), Interagency Arctic Research Policy Committee (IARPC), and the Arctic Council.

A modified Lorentz theory as a test theory of special relativity

Science.gov (United States)

Chang, T.; Torr, D. G.; Gagnon, D. R.

1988-01-01

Attention has been given recently to a modified Lorentz theory (MLT) that is based on the generalized Galilean transformation. Some explicit formulas within the framework of MLT, dealing with the one-way velocity of light, slow-clock transport, and the Doppler effect are derived. A number of typical experiments are analyzed on this basis. Results indicate that the empirical equivalence between MLT and special relativity is still maintained to second order terms. The results of previous works that predict that the MLT might be distinguished from special relativity at the third order by Doppler centrifuge tests capable of a fractional frequency detection threshold of 10 to the -15th are confirmed.

Plants as indicators of the environmental pollution

Energy Technology Data Exchange (ETDEWEB)

Michler, R

1971-01-01

Possibilities of surveying air pollution by means of indicator plants are reviewed. Though the effects of air pollutants such as sulfur dioxide and nitrogen oxides on plants are dependent on several factors such as plant species, stage of development, weather, pollutant concentration, and part of the day, it is possible to use certain plants, especially lichens, as indicators of the degree of air pollution. Comparative observations of vegetation over a period of years, and the exposure of transplanted plants in selected sites represent two different, though complementary, methods for the use of indicator plants.

Padaki, Ajay S; Popkin, Charles A; Hodgins, Justin L; Kovacevic, David; Lynch, Thomas Sean; Ahmad, Christopher S

Specialization in young athletes has been linked to overuse injuries, burnout, and decreased satisfaction. Despite continued opposition from the medical community, epidemiological studies suggest the frequency is increasing. Extrinsic pressures in addition to individual aspirations drive this national trend in sports specialization. Descriptive epidemiology study. Level 3. A novel instrument assessing the driving factors behind youth specialization was generated by an interdisciplinary team of medical professionals. Surveys were administered to patients and athletes in the department's sports medicine clinic. The survey was completed by 235 athletes between 7 and 18 years of age, with a mean age of 13.8 ± 3.0 years. Athletes specialized at a mean age of 8.1 years, and 31% of athletes played a single sport while 58% played multiple sports but had a preferred sport. More than 70% of athletes had collegiate or professional ambitions, and 60% played their primary sport for 9 or more months per year, with players who had an injury history more likely to play year-round ( P specialized athletes reporting this significantly more often ( P = 0.04). Half of the athletes reported that sports interfered with their academic performance, with older players stating this more frequently ( P specializing in a single sport before starting high school. While intrinsic drive may identify healthy aspirations, extrinsic influences are prevalent in specialized athletes. Extrinsic factors contributing to youth specialization were identified and compounded the deleterious sequelae of youth athlete specialization.

The Online Specialization Problem

Full Text Available We study the online specialization problem, where items arrive in an online fashion for processing by one of n different methods. Each method has two costs: a processing cost (paid once for each item processed, and a set-up cost (paid only once, on the method's first use. There are n possible types of items; an item's type determines the set of methods available to process it. Each method has a different degree of specialization. Highly specialized methods can process few item types while generic methods may process all item types. This is a generalization of ski-rental and closely related to the capital investment problem of Y. Azar, Y. Bartal, E. Feuerstein, A. Fiat, S. Leonardi, and A. Rosen. On capital investment. In Algorithmica, 25(1:22-36, 1999. We primarily study the case where method i+1 is always more specialized than method i and the set-up cost for a more specialized method is always higher than that of a less specialized method. We describe an algorithm with competitive ratio O(log(n, and also show an Ω(log(n lower bound on the competitive ratio for this problem; this shows our ratio is tight up to constant factors.

Context: There is increased growth in sports participation across the globe. Sports specialization patterns, which include year-round training, participation on multiple teams of the same sport, and focused participation in a single sport at a young age, are at high levels. The need for this type of early specialized training in young athletes is currently under debate. Evidence Acquisition: Nonsystematic review. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Sports specialization is defined as year-round training (greater than 8 months per year), choosing a single main sport, and/or quitting all other sports to focus on 1 sport. Specialized training in young athletes has risks of injury and burnout, while the degree of specialization is positively correlated with increased serious overuse injury risk. Risk factors for injury in young athletes who specialize in a single sport include year-round single-sport training, participation in more competition, decreased age-appropriate play, and involvement in individual sports that require the early development of technical skills. Adults involved in instruction of youth sports may also put young athletes at risk for injury by encouraging increased intensity in organized practices and competition rather than self-directed unstructured free play.

A short period undulator for MAX

International Nuclear Information System (INIS)

Ahola, H.; Meinander, T.

1992-01-01

A hybrid undulator for generation of high brilliance synchrotron radiation in the photon energy range of 60--600 eV at the 550 MeV electron storage ring MAX in Lund, Sweden has been designed and built at the Technical Research Centre of Finland in close collaboration with MAX-lab of Lund University. At the rather modest electron energy of MAX this photon energy range can be reached only by an undulator featuring a fairly short period and the smallest possible magnetic gap. Even then, higher harmonics (up to the 13th) of the radiation spectrum must be utilized. An optimization of the magnetic design resulted in a hybrid configuration of NdFeB magnets and soft iron poles with a period of 24 mm and a minimum magnetic gap of 7--10 mm. A variable-gap vacuum chamber allows reduction of the vacuum gap from a maximum of 20 mm, needed for injection, down to 6 mm during stored beam operation. A special design of this chamber permits a magnetic gap between pole tips that is only 1 mm larger than the vacuum gap. Adequate field uniformity was ensured by calibration of magnets to equal strength at their true operating point and verification of the homogeneity of their magnetization. Magnetic measurements included Hall probe scans of the undulator field and flip coil evaluations of the field integral

Full Text Available The objective of this paper is to present an empirical study of the behavior of labor industrial productivity in the regions of Brazil during the period 1996 to 2010 by groups of technology intensity. It was used the shift-share method. The results indicated that in the groups of sectors that showed positive growth rates were the competitive advantages inherent to each region that explained, in most cases, the growth of labor productivity. There was predominance of technology absorbing sectors in prejudice of sectors that generate technological spillovers. The growth of labor productivity in the extractive industry showed a upward trend, while the manufacturing industry showed downward trend, evidencing a stagnation of labor productivity at the national level. There are evidences of a reprimarization process of industrial activities through the specialization in commodities.

Since the establishment of specialization of medicine through the residency system, Spanish health care has sought to maintain a balance between established needs and trained professionals, with the aim of avoiding the deficit or excess of health specialists with its consequences. The objective of the present review is to know the working conditions of urologist specialists at the end of the residency training period. The results of a survey for urologist who completed their residency contract from 2012 to 2016 are presented, assessing working status, academic and working data during the first months after the completion of specialized training. A total of 42 surveys were collected. All respondents had a working contract within 6 months of completing their training. 71% had a temporary contract, most with duration of less than one year. There are more contract numbers in the public health system, although they increase progressively in the private sector. More than half of the respondents were satisfied with their work situation. The work insertion of the recently specialized urologists is high, reaching 100% within 6 months of finishing their specialization. Labor quality issues are not so positive, observing great working instability associated to a high proportion of temporary contracts lower than 6 months.

Hospitals are studying the focused factory concept and attempting to increase their power in a competitive industry by becoming more specialized. This study uses the information theory index (ITI) and the Herfindahl-Hirschman index (HHI) to analyze the extent of specialization by Korean hospitals that receive national health insurance reimbursements. Hierarchical regression analysis is used to assess the impact of hospital specialization on the following four aspects of operational performance: productivity, profitability, efficiency and quality of care. The results show that a focused strategy (high HHI) improves the income and adjusted number of patients per specialist through the efficient utilization of human resources. However, a diversified strategy (high ITI) improves the hospital utilization ratio, income per bed and adjusted number of patients per bed (controlling for material resources such as beds). In addition, as the concentration index increases, case-mix mortality rates and referral rates decrease, indicating that specialization has a positive relationship with quality of care.

Students in general and special education experience bullying. However, few empirical investigations have examined involvement in bullying along the bully/victim continuum (i.e., as a bully, victim, or bully-victim) among students with disabilities. A total of 816 students, ages 9 to 16, participated in the present study. From this total sample 686 were not receiving special education services (categorized as "no disability"), and 130 were receiving special education services (categorized as "observable disability," "non-observable disability," and "behavioral disability"). Data on students' involvement in bullying, office referrals, and prosocial behavior were collected. Results indicated that students with behavioral disorders and those with observable disabilities reported bullying others more and being victimized more than their general education counterparts. Students with behavioral disorders also had significantly more office referrals than students in general education. Seventh graders in general education reported more bullying behavior than sixth graders and ninth grades in general education. Fifth graders in general education reported more victimization than students in all other grades in general education. However, the grade differences were not significant for students in special education. No gender differences on bullying and victimization were found. Students with disabilities reported less engagement in prosocial behaviors than their general education peers. Implications for bullying prevention and intervention across both general and special education are discussed. Copyright © 2012. Published by Elsevier Ltd.

Full Text Available The mainstay of radical treatment for patients with breast cancer (BC is a surgical intervention: radical mastectomy (RME of different modifications or organ-sparing operations. In the preoperative period, the tasks of therapeutic exercises (TEs are psychological preparation of a patient for active participation in his / her treatment, as well as complete breath training. Classes are done in a group of convalescents, by applying dynamic and static breathing exercises. In the early postoperative period, the tasks of TEs are to prevent hypostatic pneumonia, surgical-site shoulder joint stiffness and to improve systemic and regional blood and lymph circulation. Analysis of 1235 patients who had undergone RME and 212 patients who had radical resection showed that restricted shoulder joint motion due to hand immobilization in an adducted position and late initiation of TEs occurred in 44.6 and 33.5 % of the patients, respectively. Individual TEs classes include breathing exercises, position treatment, and special exercises to restore shoulder joint function and to control posture. Lymphadenectomy and failure to ligate intersected lymphatic vessels lead to inevitable lymphorrhea and seroma. Analysis of 1447 patents indicated that early initiation of TEs failed to affect seroma duration and extent and wound dehiscence. In the latter (that, according to the author»s data, occurs in 3.7 % of cases after RME and in 9.2 % after preoperative radiotherapy, TEs are limited by position treatment until the wound heals or secondary sutures are applied. The tasks of the late postoperative period are recovery of the full range of shoulder joint motion, normal posture, cardiovascular and respiratory adjustments to increased physical exercises, and general tonic exposure. The paper gives TEs sets developed for each period.

Studies among students with special educational needs (SEN) in separate special schools (SSS) and mainstream schools (MS) are particularly applicable to educational attainment and social participation. However, indicators of health and wellbeing have rarely been considered. This study investigates two related topics: first, health and wellbeing differences between students with SEN in special schools (SSS) and students without SEN in regular schools, and second, the rarely considered question whether health and wellbeing among students with SEN differ between school settings (i.e. MS vs. SSS). Bivariate and multilevel analyses are applied with data from the German National Educational Panel Study (NEPS) with 5267 students (grade 7). After having controlled for background characteristics, students in SSS report higher likelihoods of poor self-rated health compared to students in higher track schools. Self-rated health of students with SEN does not significantly differ between MS vs. SSS. For life satisfaction, students with SEN show higher likelihoods of low life satisfaction when attending MS. Teachers in inclusive settings are encouraged to establish class work and teaching that support a real change from class placement to inclusive culture in order to suitably support students with SEN.

This investigation employs categorical content analysis processes as a mechanism to examine trends and issues in a sampling of highly cited (100+) literature in special education journals. The authors had two goals: (a) broadly identifying trends across publication type, content area, and methodology and (b) specifically identifying articles with disaggregated outcomes for students with learning disabilities (LD). Content analyses were conducted across highly cited (100+) articles published during a 20-year period (1992-2013) in a sample ( n = 3) of journals focused primarily on LD, and in one broad, cross-categorical journal recognized for its impact in the field. Results indicated trends in the article type (i.e., commentary and position papers), content (i.e., reading and behavior), and methodology (i.e., small proportions of experimental and quasi-experimental designs). Results also revealed stability in the proportion of intervention research studies when compared to previous analyses and a decline in the proportion of those that disaggregated data specifically for students with LD.

Full Text Available The purpose of this paper is mapping studies indexed between the years of 2002 and 2011 in the educational field and evaluated like A1 or A2 by the database Qualis Capes, in the three years 2010-2012, in order to research ways that studies with families of children with special educational needs have been made. For this, we analyze elements such as: annual evolution of the studies, subjects analyzed, adopted and thematic instruments used to collect data from database searches “Scielo” and “Capes Journal” and a multitude of descriptors combined. The criterion for considering the family was that the research should contain the following keywords: family, family relationships, parental relationships, parents and siblings crisscrossing: special education, people with special educational needs, inclusive education, inclusion, autism, autistic, gifted, high ability, cerebral palsy, low vision, blindness, deafness, pervasive developmental disorder, Down Syndrome, disability, intellectual disability, physical disability, visual impairment, hearing impairment and multiple disabilities. Thus, the papers were obtained by intercrossing these descriptors, but it was selected those containing one of these words. With this, we found a total of 36 papers in national journals indexed in the area of Education. The data showed that there was a growing body of empirical research in this area.

1996-02-01

This report is aimed at presenting the results of the energy efficiency evolution in Italy for the 1970-1992 period Results come from the data-base developed under the SAVE/EnR project on `Cross countries comparison on energy efficiency indicators`. In order to be comparable among countries, efforts have been made to harmonize the data collection as well as the definition and the calculation of energy efficiency indicators. Selected indicators are considered in order to illustrate the potentiality of the project (around 200 different energy efficiency indicators can be calculated and presented). Emphasis is put on the interpretation of the so-called `techno-economic indicators` as well as explanatory indicators both for the economic and techno-economic approaches. Industry, transport, tertiary, residential and transformation sectors have been analyzed.

To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

To evaluate whether prenatal care in a specialized diabetes in pregnancy program (DMC) improves compliance with completion of the 2-h 75 g oral glucose tolerance test (2HrOGTT) in GDM women. A retrospective cohort study of GDM women delivering in a university health system between January 2011 and March 2014 was performed. Women were divided into two groups: those receiving care in prenatal clinics over an 18-month period prior to the establishment of the diabetes in pregnancy clinic (pre-DMC) and those receiving prenatal care in a specialized diabetes in pregnancy clinic (post-DMC). The primary outcome was completion of the 2HrOGTT postpartum. Clinical characteristics associated with 2HrOGTT completion were evaluated. Time trend analysis was performed to evaluate month to month variation in 2HrOGTT compliance for secular trends. A total of 292 women were analyzed, 147 post-DMC and 118 pre-DMC. The 2HrOGTT was ordered more frequently in the post-DMC compared to pre-DMC (90.0 versus 53.0%, p prenatal care post-DMC were 2.98 times more likely to complete the 2HrOGTT compared to those receiving care pre-DMC (OR 2.98 [1.34, 6.62], p = 0.007). Providers were 5.9 times more likely to order the recommended testing for GDM women who attended the postpartum visit in the post-DMC period. GDM women who receive prenatal care in a specialized diabetes in pregnancy program are more likely to complete the 2HrOGTT in the postpartum period.

In April 2008, the specialization in departments of obstetrics and gynecology was conducted in Sennan area of Osaka prefecture in Japan, which aims at solving the problems of regional provision of obstetrical service. Under this specialization, the departments of obstetrics and gynecology in two city hospitals were combined as one medical center, whilst one hospital is in charge of the department of gynecology and the other one operates the department of obstetrics. In this paper, we implement a cost-benefit analysis to evaluate the validity of this specialization. The benefit-cost ratio is estimated at 1.367 under a basic scenario, indicating that the specialization can generate a net benefit. In addition, with a consideration of different kinds of uncertainty in the future, a number of sensitivity analyses are conducted. The results of these sensitivity analyses suggest that the specialization is valid in the sense that all the estimated benefit-cost ratios are above 1.0 in any case.

The eastern Mediterranean has been assigned as one of the most responsive areas in climate change, mainly with respect to the occurrence of warmer and drier conditions. In Greece in particular, observations suggest prominent increases in the summer air temperature which in some areas amount to approximately 1 0C/decade since the mid 1970s, while Regional Climate Models simulate further increases in the near and distant future. These changes are coupled with simultaneous increase in the occurrence of hot extremes. In addition to changes in the frequency and intensity of hot extrems, timing of occurrence is also of special interest. Early heat waves in particular, have been found to increase thermal risk in humans. The study explores variations and trends in timing, namely the date of first and last occurrence of hot extremes within the year, and subsequently the hot extremes period (season), defined as the time interval (number of days) between first and last hot extremes occurrence, over Greece. A case study for the area of Athens covering a longer than 100-years period (1897-2015) was conducted first, which will be extended to other Greek areas. Several heat related climatic indices were used, based either on predefined temperature thresholds such as 'tropical days' (daily maximum air temperature, Tmax >30 0C), 'tropical nights' (daily minimum air temperature, Tmin >20 0C), 'hot days' (Tmax >35 0C), or on local climate statistics such as days with Tmax (or Tmin) > 95th percentile. The analysis revealed significant changes in the period of hot extremes and specifically elongation of the period, attributed to early rather than late hot extremes occurrence. An earlier shift of the first tropical day and the first tropical night occurrence by approximately 2 days/decade was found over the study period. An overall elongation of the 'hot days' season by 2.6 days/decade was also observed, which is more prominent since the early 1980s. Over the last three decades, earlier

Log-periodic self-similarity: an emerging financial law?

A hypothesis that the financial log-periodicity, cascading self-similarity through various time scales, carries signatures of a law is pursued. It is shown that the most significant historical financial events can be classified amazingly well using a single and unique value of the preferred scaling factor lambda=2, which indicates that its real value should be close to this number. This applies even to a declining decelerating log-periodic phase. Crucial in this connection is identification o...

Periodic depuration of anthracene metabolites by rainbow trout

International Nuclear Information System (INIS)

Linder, G.; Bergman, H.L.

1984-01-01

Rainbow trout Salmo gairdneri, statically exposed to 36 μg/liter anthracene (including 9- 14 C-C anthracene), bioconcentrated the polynuclear aromatic hydrocarbon 200 times the exposure concentration over 18 hours. Then, during a 96-hour clearance periods, mass-balance analysis of fish and water samples indicated that anthracene was rapidly converted to polar metabolites(s), then eliminated periodically. Maximum depuration occurred during the dark phase of a 16-hour-light: 8-hour-dark photocycle. Of the 2-3% contribution of 14 C metabolites(s) to the total 14 C residue, nearly half came from the bile. This periodic depuration may be circadian, although this requires confirmation by further work; to the extent it affects metabolic fate of bioconcentrated organics, periodic depuration undoubtedly contributes to differences between predicted and observed bioconcentration factors
