This study was carried out to determine physiological and biochemical changes in C. moschata inoculated with a Nigerian strain of MWMV isolated from Lagenaria breviflora in Calabar, Nigeria. The virus infection resulted in significant (p#0.05) reductions in plant height, leaf area and number of leaves produces with highest percentage difference of 39.3% (42 PID), 60.9% (35 PID) and 25.7% (49 PID), respectively. There was a significant (p#0.05) difference in chlorophyll content between inoculated and healthy plants. The chlorophyll content of inoculated plants at all stages of growth was lower compared with the healthy plants. Chlorophyll b content was higher than Chl a in both inoculated and healthy plants. Chlorophyll a, b and total Chlorophyll were significantly reduced in inoculated plants when compared with the healthy ones. Of the twelve photochemicals screened, alkaloids, glycosides, saponins, tannins, terpenoids, steroids, polyphenols and reducing sugars were present while phlobatanins, anthraquinones and hydroxymethyl anthraquinones were absent. Moroccan watermelon mosaic virus engendered reductions in alkaloids (32.1%), reducing sugars (42.0%), saponins (33.6%), terpenoids (25.0%) and steroids (15.0%) and increase in inoculated samples of glycosides (14.8%) and flavonoids (12.5%). Effect of MWMV on proximate compositions of C. moschata revealed significant p#0.05) reductions in lipid (25.0%) and ash (14.6%) and significant (p$0.05) increases in protein (23.4%) and fibre (10.5%). Effect of the virus on carotene, vitamin A and C were insignificant. Infection of MWMV also led to significant decreases in the contents of K (48%), Fe (28.6%), Zn (25.0%) and Mg (22.0%), while Cu recorded 100% increase in inoculated samples. Marginal increase in Ca and P were recorded in inoculated samples. Infection of MWMV on antioxidants caused significant increase in inoculated samples of hydrocyanic acid and insignificant increases in total and soluble oxalate and phytic acid. Increases recorded in the antioxidant contents in plants inoculated with MWMV resulted in reduced bioavailability of minerals in the vegetable. Reduction in chlorophyll contents in inoculated plants would be a major factor explaining poor growth of host plants with attendant reductions in mineral elements of C. moschata. Changes in physiological and biochemical parameters induced by MWMV altered vital metabolic processes of C. moschata.


A model is presented for calculating tracer concentrations in a mixer with a well-defined circulation path. The model is applied to the airlift reactor. It is shown that the outcome corresponds well with the experimental data given in the literature. However, the model points to a discrepancy in the interpretation of the data. This discrepancy is the time interval between peak concentrations


Study Design. A retrospective study. Objectives. To evaluate the impact of upper instrumented vertebra (UIV) orientation including the fused spinopelvic angle (FSPA) on proximal junctional kyphosis (PJK). Summary of Background Data. PJK is a challenging complication after adult spinal deformity (ASD) surgery. Some studies proposed UIV orientation act as a risk factor of PJK, but there remain debates because UIV orientation is changed by position. Therefore, we investigated the relationship between the FSPA, a novel parameter for the relationship between UIV and pelvis which did not change by position, and PJK. Materials and Methods. ASD patients who underwent long-segment fusion to the pelvis and followed up for more than two years were included. Comparative analysis was performed on spinopelvic parameters including UIV orientation parameters (UIV slope angle and FSPA) between PJK and non-PJK group. Binary regression analysis was conducted to find out the risk factors for PJK. And correlation analysis was conducted to find out the parameters that affect the FSPA. Results. A total of 190 patients were included. PJK incidence was 13.2% (25/190). PJK group showed a significantly greater postoperative UIV slope (21.3° vs. 18.8°, P=0.041) and significantly lesser postoperative FSPA (−0.9° vs. 4.5°, P<0.001). In binary regression analysis, only FSPA acted as a risk factor of PJK (odds ratio=0.920, P=0.004). The FSPA has strong positive correlation with pelvic incidence (PI)-lumbar lordosis (LL) (r=0.666, P<0.001) and negative correlation with lordosis distribution index (LDI) (r=−0.228, P=0.004). Conclusion. The FSPA is a fixed parameter which is not dependent on position. A reduction of the FSPA increases the risk for PJK. The FSPA can be adjusted through PI-LL and LDI. Thus, surgeons should increase the FSPA by adjusting the PI-LL and LDI during ASD surgery to prevent PJK.


The controversy that led to the conviction of the Puritan exorcist John
Darrel for fraud in 1599 has mainly been viewed by historians in the context of
the struggle between Puritans and the Church of England. Darrel's activities
have been seen as Puritan propaganda, whilst the authorities' reaction has been
seen as part of their campaign against Puritanism. Their clamp down on
Darrel's activities has also been seen as contributing towards increasing
scepticism towards demonic possession in early modern England, especially in
cases involving witchcraft.
This thesis argues that the Darrel controversy cannot be read solely as a
manifestation of the Puritan/establishment conflict, as it will demonstrate how
the controversy was actually part of the broader re-assessment of the role of the
supernatural in the contemporary world following the Reformation, and that
anti-Catholicism, in particular hostility towards the Catholic rite of exorcism,
played a significant role in informing sceptical attitudes towards demonic
possession.
Focussing upon the work of the Puritan preachers John Deacon and John
Walker, it will also challenge the Puritan/establishment dichotomy over
possession. Their work denied the possibility of possession in their own time by
drawing on and elaborating existing medical, natural philosophical and
theological arguments, particularly the doctrine of the cessation of miracles.
Their work was significant because it was the first work that systematically
explored the intricacies of the phenomenon of possession, and it offered an
alternative way of thinking about demonic affliction, namely the category of
obsession. Writings that appeared following the Darrel controversy demonstrate
an awareness of Deacon and Walker's arguments, and also reveal how the idea
of obsession was absorbed into broader demonological thought, thus
highlighting how Deacon and Walker's work was much more significant than
has previously been thought.


The utility of ultrasound in diagnosis of pancreatic lesions is well known (1). Diagnosis of disease in the tail of the pancreas is made difficult by the proximity of the distal transverse colon and splenic flexure. The three cases of false-positive diagnosis of pancreatic tail lesions presented here point out the necessity of differentiating a feces-filled splenic flexure from a true lesion.


The Federation of European Biochemical Societies (FEBS) awarded FEBS Long‐Term Fellowships from 1979 until 2020, at which time the scheme was replaced with the FEBS Excellence Award. Over four decades, FEBS awarded a huge number of Long‐Term Fellowships, helping to support and promote the careers of excellent young researchers across Europe. To celebrate the exciting work performed by the FEBS Long‐Term Fellows, we present here a special 'In the Limelight' issue of FEBS Open Bio, containing four Mini‐reviews and four Research Protocols authored by the fellows themselves. The four Review articles provide timely updates on the respective research fields, while the Research Protocols describe how to perform challenging experimental methods in detail. We hope this issue will be a valuable resource for the community, and a celebration of the high‐quality work done by young scientists.


The present work consists of an arduous investigation and development to a problem identified in a technology company that recently ventured into Colombia. This paper addresses the following theories: value chain, supply chain and the basic principles of business administration for its optimal development and implementation. Once these theories are analyzed, they are implemented for five months to achieve results that were not seen to come in the short term in inventory control and shop fitting.


A determination of the health status of process (SOH) comprises the steps of: - determining a DC impedance of at least one accumulator; - determining at least one confidence coefficient function of at least one selected from the variable current, temperature or the charging state of said at least one accumulator or their derivatives or integrals over time; - continuously determining the battery condition at a given time from the state of health of the battery at a preceding time corrected according to said impedance at the given time and weighted by the at least one coefficient confidence the method allows determination of the health status of a battery that is reliable and has greater stability and robustness than known methods.


As wavelet can only reflect the zero-dimensional singularities of signal and cannot provide an optimally sparse representation of facial contour and five sense organs' curve information of face image,a face recognition algorithm based on second-generation curvelet transform is proposed.The proposed method firstly transforms face image with second-generation curvelet to get low frequency coefficients with facial basic information,and then reduce dimensions with the two-directional two-dimensional principal component analysis((2D)2PCA),at last the test face is recognized by using the nearest distance algorithm.Experimental results on ORL and Yale face database show that the proposed method has higher recognition rate and less recognition time than the method based on wavelet.


R adial scars (RS), an infrequent and typically incidental microscopic feature of benign breast biopsies, can be the source of considerable confusion and controversy when seen as spiculated mammographic masses or detected as clinically palpable abnormalities, and of diagnostic error especially in frozen section and stereotactic core material. The frequency of their association with significant proliferative changes and in particular marker lesions, atypical lobular hyperplasia (ALH), atypical ductal hyperplasia (ADH), lobular carcinoma in situ (LCIS), and carcinoma both in situ and invasive, appears to increase with the size of the RS, and has raised questions of whether stereotactic biopsy is contraindicated because of its potential for missing significant findings and for misdiagnosis. However, the true frequency of marker lesions in association with RS has not been defined; potentially it may be no greater than for other specific lesions such as sclerosing adenosis, papilloma, fibroadenoma, etc. This association has also suggested RS as the histogenetic lesion of origin for tubular carcinoma (1). In their timely pathologic analysis of the Armed Forces Institute of Pathology (AFIP) experience with RS associated with marker lesions and carcinoma, Alvarado-Cabrero and Tavassoli review these various concerns and touch on a recent analysis of Jacobs et al. (2) which demonstrated a statistically significant increased relative risk (RR) of subsequent breast carcinoma for the presence of an RS in a prior benign biopsy. The RR was not calculated on subsequent invasive carcinoma alone, but for ductal carcinoma in situ and invasive carcinoma, and thus may be somewhat inflated compared to the RR determined for ADH, ALH, etc. Although the analysis of Jacobs et al. (2) was corrected for confounding factors (SAS computer software; SAS Institute, Cary, NC), striking differences are evident in patients with a subsequent breast carcinoma between those with a prior benign biopsy and an RS and those without. Seventyfive percent of the former versus 49%. of the latter group were postmenopausal (62% of the former versus 40% of the latter were over 55 years of age); and 34.4%. of the former versus 14.8% of the latter had a first-order family history—a 2.3-fold difference. Although some of the RRs are quite large (e.g., 5.3 for ADH and RS), because of the small numbers, the range of confidence limits is also quite wide: 2.4–11.6 for ADH and RS. Prospective studies will be required to substantiate the RR of subsequent invasive breast carcinoma associated with an RS and to determine whether such lesions can be adequately diagnosed by stereotactic biopsy.


The number of threatened species in their natural habitat is increasing, thus it is urgent to implement new conservation strategies. The advances in biotechnology, namely the use of in vitro culture techniques, make this possible. This work is mainly focused on two endemic species from the Algarve region, Tuberaria major and Plantago algarbiensis. Despite the lack of information about these two species it is known their threaten state. For T. major the in vitro germination of seeds was studied, and with the originated seedlings a micropropagation protocol was initiated in order to mass propagate this species. The MS medium supplemented with 0,2 mg l Zea was the most effective to produce high number of shoots. During the rooting phase the reduction of MS macronutrients was the most important factor. After 6 weeks of acclimatisation, 97% of survival was obtained. At a later stage two techniques were studied for conservation of T. major germplasm, the cryopreservation of seeds and cryopreservation of shoot tips, which were studied in three different methods, the vitrification, the droplet-vitrification and the encapsulation-dehydration. The encapsulation-dehydration showed to be the most effective method, in which 67% of the cryopreserved apices formed shoots. Seeds germinated in vitro were used to establish cultures of P. algarbiensis and from the shoots obtained leaf explants were isolated and used to study the production of shoots via organogenesis. The best results in terms of shoot formation were obtained in MS medium supplemented with 4 mg l BA + 1 mg l IAA. This work demonstrates that the in vitro conservation techniques could be used with success for the conservation of the species T. major and P. algarbiensis. Key-words: Conservation; endangered species; in vitro germination; micropropagation; organogenesis; in vitro cryopreservation.


Agritourism is a potent economical element that has been extensively used in developing countries to escalate the financial growth of the national income. In China, it is a major corporate zone which is elevating the socio-economic progression by playing its significant role in expanding country's economic growth and development. It plays a substantial part in activating the ruler areas and reveals number of obstacles related. The main objective of this paper is to disclose the prospects of agritourism development in China that can be a key factor in sustaining progressive national economy. The current studies concluded that agritourism can be a drive for sustainable development of local community. An important feature is to fortify attentiveness of local communities regarding welfares resulting from the development of this non-agricultural source of income at various striking tourism sites. It will eventually lead to lessening of redundancy, job creation in sectors serving agritourism, revenue growth, alleviating poverty and will improve living standards of population vigorously involved. Therefore, agritourism in China has the prospects to nurture the perception of the particular community concerning sustainable development. Keywords: agritourism, socioeconomic prospects, rural development, revenue, sustainability


The presented doctoral thesis deals with the study of nucleation and crystal growth in chalcogenide glasses. Although a lot of papers have been published about nucleation and crystal growth during past decades and many theories have been suggested, there is still a need for more information about these complicated processes in chalcogenide glasses, in particular with respect to their indispensable technological applications. It should be noted that the essential portion of the present knowledge on nucleation in glasses comes from the studies in oxide glasses. This thesis extends the understanding of crystal nucleation and growth behavior in chalcogenide glasses. The thesis consists from 5 papers supplemented with the theoretical insight into the crystallization process and the summary of main goals of the work.
The first objective of the thesis was the study of nucleation kinetics in chalcogenide glass and testing of the applicability of so far proposed theories and their improvements for description of steady-state and transient nucleation. The study on nucleation was performed in Ge1.8Sb36.8S61.4 thin films of 1 ěm thickness using isothermal in-situ annealing and optical microscopy. The time evolution of nuclei number at different temperatures revealed transient behavior, which was described by Shneidman theory that provides values of steady-state nucleation rate, induction period and time-lag. The nucleation rate data were discussed in terms of classical nucleation theory (CNT). Some predictions and improvements of CNT were tested and applied.
The second objective of the thesis was the extension of studies on crystal growth kinetics in chalcogenide glasses using direct (optical and electron microscopy) and indirect (X-ray diffraction, differential scanning calorimetry, thermomechanical analysis) analytical methods. The combination of more approaches gave better insight into the crystal growth process. The studies were performed in both, bulk glasses and thin films, for the following glassy systems: Se-Te, Ge-Sb-Se and As-Se. The results were described on the basis of standard and corrected growth models.


Crime, present since the beginning of humankind, is known to be multifactorial. Factors implicated are socioecological, psychological, and even biological. Indeed, recent brain research has found that thoughts and feelings are strictly connected with dysfunction of, or damage to, synapses affecting important brain structures, such as the orbital region, the cingulated gyrus, the hippocampus, the amygdala, and the prefrontal cortex. Simply put, different regions of the brain talk, or do not talk, to one another. Although that may help us to understand the neurophysiopathology at the basis of criminal acting-out, it does very little to help us understand the motivations for such actions or to address the prevention of such behavior. Over the centuries, societies have attempted, with more or less success, to control crime through the use of moral and legal rules, among them the lex talionis, the Hammurabi Code, the Mosaic Law, the Justinian Code, and the Napoleonic Code. More recently, criminal codes have been enacted in various countries. The application of these laws has fluctuated with the mores of society, from a liberal approach to a draconian approach, generally with poor results. Basically, the origins of criminal acting-out are within people, their view of themselves, and their relationship with others, and often laws and punishment fall short of addressing the real issues. Among the goals of punishment are to have offenders repent for their actions, to make them pay for their offenses, or to dispense a poena forensis for punishable acts as a Kantian categorical imperative. The types of punishment can be summed up by the four R's: retaliation, restitution, retribution, and rehabilitation. Retaliation, a primitive means of revenge, is the oldest way of dealing with an offense. It can be seen as simple, gut-reaction justice. Restitution avoids any psychological or moral judgments and tries to achieve restoration to a previous state through monetary payments or services to victims or society. Obviously, it cannot address serious violent crimes, such as rape or murder. Retribution is based on the theory of just deserts and considers the intentionality of the crime. It supports the contention that punishment, as Cesare Beccaria said, must fit the crime and the culpability of the offender. Retributists argue that offenders deserve to be punished if they harm someone because they have gained an advantage over others by their actions

Early Detection of Diabetic Retinopathy is paramount in prevention of vision loss. This study proposes a novel approach to the automatic detection of diabetic retinopathy (DR) using fundus images. This paper compares other techniques and does comparative study of Convolutional Neural Networks (CNNs) and the ResNet architecture to analyze fundus images and classify them based on the severity of DR. The study uses the APTOS 2019 Blindness Detection dataset, a publicly available dataset of over 5,000 high-resolution retinal images collected from patients with varying degrees of DR. The study concludes that the proposed approach provides a promising solution for the automatic detection and classification of DR.


what may appear on first glance to be a call for an actor-free theatre. "In Bufano's vision, puppets and actors will share the stage, doing what each does best" (90), which, Bell explains, could mean that in a play like Hamlet, a live actor should play the title role, but puppets might be better suited for supernatural characters like the ghost of Hamlet's father. For the emerging artists that were newly dubbed "puppeteers" (the term is less than a hundred years old), Craig's theories were the means by which they injected themselves into "serious" theatre.


The paper undertakes a dynamic analysis for service quality in the electricity distribution in Brazil between 2010 and 2014 based on Malmquist indexes constructed upon Data Envelopment Analysis (DEA) distance functions. The motivation for the less usual consideration of efficiency frontiers for service-quality builds on previous static applications in the context of telecommunications as given by Facanha and Resende (2004), Resende and Facanha (2005) and Resende and Tupper (2009). The analysis treats undesirable technical indicators as inputs and desirable consumer satisfaction indicators as outputs. The bootstrap- corrected Malmquist indexes indicated that service quality is an important concern as the evidence respectively indicates quality deterioration in 38.1 %, quality stagnation in 40.5 % and quality improvement only in 21.4 % of the cases. When one decomposes the Malmquist index, the evidence does not suggest relevant frontier shifts and indicates a dominant role for the catch-up effect.


Previous research Indicates soma relationships between Altruism, self-esteem and mood. The nature of the re lationship, however, Is not clear. Does feeling good about oneself make It likely that someone will help another individual or does helping another Individual make someone feel good? How are mood and self-esteem affected by this seemingly circular relationship? The purpose of this study was to Investigate this re lationship by examining the effects of self-esteem and mood on volunteering. We also investigated changes in self-esteem and mood as a function of volunteering for a task which had neutral, altruistic or egocentric incentives. The results showed that subjects with low self-esteem tended to volunteer less for a task with egocentric incentives. There were no sig nificant differences in mood between those who did and did not volunteer. We also found that the act of helping, whether altruistically or egocentrically motivated, significantly increased the self-report of transient mood states, but not the more enduring trait of self-esteem. No change was found in mood, or self-esteem, ratings for subjects in the control group, who were given no incentives for helping.


In this paper, we show an addition formula for a class of Mellin transformable functions using Ramanujan's master theorem. Also, we get the associated addition formula of Gaussian functions in terms of the Bessel functions and Green function of the space-fractional biharmonic heat equation is obtained with respect to the quartic Levy stable functions.


PROBLEM TO BE SOLVED: To provide a control device for a game machine, effectively preventing the situations such as fraudulent replacement and fraudulent remodeling of a control element. SOLUTION: In a control device 1, right and left ones out of the respective screw holding parts 9, 9 ... provided on an upper cover 6 to be easily cut are screwed to screw engagement bodies 20, 20 of a lower cover 5 by screws 13, thereby joining the upper cover 6 and the lower cover 5. The respective screws 13, 13 utilize a one-way clutch mechanism, so that when a head part 15 is rotated in the normal direction, a needle built in the head part 15 transmits the turning force to a shaft member 14 to rotate the shaft member 14, and when the head part 15 is rotated in the reverse direction, the needle does not transmit the turning force to the shaft member 14, thus holding the shaft member 14 in a non-rotating state. Further, when the head part 15 is rotated in the normal direction with strong force, the needle is held without being pressed to the shaft member 14. COPYRIGHT: (C)2011,JPO&INPIT


1. Methods. The decision for VA versus VV support for neonatal respiratory ECMO is dependent on the patient, surgeon, and center. Open cut down exposure for VA and VV cannulation and percutaneous VV cannulation are all reasonable options if performed safely with the proper expertise. 2. Cannulation technique (ELSO Red Book, 5th edition, Ch 12).1 In most situations, cannula selection occurs after cut down with direct inspection of the vessels. Some surgeons perform bedside ultrasound of the right neck vessels before cannulation to estimate the vessel size and guide selection. Some vasospasm can be expected, so a cannula with a diameter (size in Fr divided by 3.14) that is 80% of the diameter of the vessel can reliably be chosen. Direct cut down cannulation. Cannulation is usually done in the ICU with full sterile preparation and an OR team. Which vessel to cannulate first depends on surgeon preference? Many prefer to cannulate the artery first as it can be deeper than the vein depending on neck position. Others argue that venous cannula should be inserted first as it is secured at 6–8 cm and the arterial cannula is inserted only 2–3 cm. Furthermore, given that the arterial cannula is clamped while the venous cannula is placed, there is an increased risk of developing an arterial clot, which would be more significant than a venous clot. Direct handling of the vessels is minimized as much as possible to avoid spasm. If the vessels are very small, if there is difficulty with cannulation, or if spasm occurs, then fine stay sutures placed in the proximal edge of the vessel are very helpful. Chest x-ray should be obtained to verify venous cannula tip location in either the right atrium or in the IVC for a bicaval dual-lumen cannula. Echocardiography (ECHO) can also be used to assess position of the cannula tip, particularly during dual-lumen cannula placement. Femoral cannulation is not appropriate for neonates. Percutaneous cannulation. Some centers have employed percutaneous cannulation techniques for VV ECMO in neonates. This can be accomplished through ultrasound-guided right jugular vein access and gradual dilation of the vessel over a wire using the Seldinger technique. ECHO and/or fluoroscopy should be used to assure safe positioning of the wire during dilation and ultimate placement of the cannula tip to avoid vascular and cardiac injury. 3. Venous drainage. In most cases, there is no need for further venous drainage as suitably sized cannulae will give adequate support. If venous drainage is inadequate, a separate drainage cannula may be required. The cephalic end of the jugular vein is the most common location. If possible, a 10 Fr or 12 Fr arterial cannula with a distal hole should be used for the cephalic drain, as an 8 Fr cannula will likely thrombose. Some centers routinely place a cephalad venous cannula, but this is an institutional preference and is not normally required. The femoral veins are usually insufficiently sized and should not be accessed in neonates. Central cannulation could be considered for inadequate venous drainage.

The marine 3D environment for AUV work is quite complicated, and it is difficult to solve the recovery path directly. This paper adopts the recovery path planning algorithm based on Dubins Curve. When AUV enters the recovery area, the 3D planning is first reduced to the 2D xoy-plane planning and z-plane height planning. According to the current attitude of AUV and the final attitude required by the recovery platform, calculate all possible Dubins paths by a certain degree of repetition and relative positional relationship, and choose a collision-free shortest path in the xoy-plane. Then, the height planning of the obstacle avoidance is performed in the z-plane, and synthesize them to get a 3D recovery path. The simulation results show that the recovery path given by the proposed algorithm can make the AUV navigate underwater along the smooth trajectory of curvature, and safely enter the recovery platform from the designated position in the desired attitude.

A variational inequality approach is utilized to study traffic network equilibrium problem with non-additive path cost. An equivalent variational inequality model is presented, which includes the existing additive models as its special case. Existence and uniqueness of solutions to the model under some weak conditions are investigated. This study provides a powerful tool to further explore the traffic network equilibrium problem in a general situation.


Our knowledge of the action of extracts of the ovaries is in a highly unsatisfactory condition, although recently some progress has been made in solving some of the problems in connection therewith. The difficulties connected with the work are not hard to understand. In the first place, the ovary contains more than one structure which might be capable of elaborating a hormone. We have to consider the ovary as an entity; also the corpus luteum or the ovary without the corpus luteum; and, finally, the liquor folliculi, to say nothing of the much discussed interstitial cells. We have to consider the juices expressed from the ovary or watery extracts of the ovary, alcoholic extracts and lipoid extracts—all of which have been employed in experimental work. Finally, there has been until recently the difficulty connected with the obtaining of accurate criteria for measuring the activity of these various preparations on the


The opportunity high school as it has developed in recent years is a specialized form of the remarkable growth of secondary education in the last two or three decades. Three distinct but complementary factors are involved in the development of this institution: (i) Industry and commerce do not have appropriate opportunities for the advantageous employment of young persons from fourteen to about twenty years of age. (2) When some sort of work for young people is found in commerce and industry, there is often urgent need for further training of a general and specialized type to fit the young people into the jobs which they undertake. (3) The regular secondaryschool curriculum now current does not fit, and seemingly cannot be made to fit, the needs of these groups of people. Whether opportunity schools will ultimately become solidified into permanent institutions for this specialized service cannot be forecast at this time. The evolution of these schools may be similar to that of other educational institutions. After they have done the pioneer work, it may be possible for them to coalesce with the main trends of secondary education. It is the purpose of the present article to trace the development of an opportunity school in a single school system and to note the factors that may have general application. The continuation school in Berkeley, California, was founded in 1920 in accordance with provisions of law in the state of California. This law requires that pupils must attend school until eighteen years of age. Upon fulfilling certain requirements, they may be employed after fourteen years of age, but they must attend school a minimum of four sixty-minute hours a week. Parents and employers alike are obliged to see to it that this requirement is fulfilled. The school at first was housed jointly with the local high school, since the pupils concerned were of high-school age. As the years


Abstract Soft tissue masses have a varied presentation. Though all masses cannot be optimally imaged on USG, its easy availability, real-time capability, and cost-effectiveness, as well as the freedom it provides to examine in any direction, make it an automatic choice as a first-line modality. Though Doppler is an exciting modality, it has its limitations and is not always rewarding. USG is more useful for superficially located masses. The role of USG is to provide information about the extent of the mass, its nature, and its relationship to the surrounding structures. One important aim is to differentiate between a pseudotumor and a true mass lesion. Doppler can provide additional information in selected cases. USG can play a pivotal role in guiding a needle for obtaining a sample for tissue diagnosis. Benign lesions are more common than malignant ones, in day-to-day practice. As with any other musculoskeletal examination, technical expertise and a sound knowledge of musculoskeletal anatomy are important.


Investigation of hash join algorithm on multi-core and many-core platforms showed that carefully tuned hash join implementations could outperform simple hash joins on most multi-core servers. However, hardware-oblivious hash join has shown competitive performance on many-core platforms. Knights Landing (KNL) has received attention in the field of parallel computing for its massively data-parallel nature and high memory bandwidth, but both hardware-oblivious and hardware-conscious hash join algorithms have not been systematically discussed and evaluated for KNL's characteristics (high bandwidth, cluster mode, etc.). In this paper, we present the design and implementation of the state-of-the-art hardware-oblivious and hardware-conscious hash joins that are tuned to exploit various KNL hardware characteristics. Using a thorough evaluation, we show that:1) Memory allocation strategies based on KNL's architecture are effective for both hardware-oblivious and hardware-conscious hash join algorithms; 2) In order to improve the efficiency of the hash join algorithms, hardware architecture features are still non-negligible factors.


The reaction of oxygen atoms (in the absence of molecular oxygen) with chlorine has been studied in a discharge flow system between 1 and 2 mm Hg total pressure and between 174 and 396°K. The rate of reaction of O was first order with respect to both [O] and [Cl2], and no dependence of the second-order rate constant k1 upon total pressure, or upon the nature of the surface of the tube, was detected. The mechanism of reaction can be represented by O+Cl2→ClO+Cl (1) ClO+O→Cl+O2(2) with k2≫k1. The value for k1 fitted either of the expressions k1=(5.8±1.5)× 1012 exp [(–3100±100)/RT] or (2.3±0.7)× 1011T½ exp [(–2900±100)/RT] cm3 mole–1 sec–1 in the range 174–396°K. The magnitude of the activation energy is consistent with an approximate correlation of activation energy with heat of reaction for related transfer reactions of an oxygen atom with a diatomic molecule.


In order to meet the requirements for the Olympic Games Qingdao 2008 sail boat racing and the construction of Qingdao international aquatic sports base, the main problems are discussed as follows: (1) the diel variation characteristics of weather with a wind speed less than 3 m/s in the Qingdao inshore area in August and September and its relations to the land sea wind circulation development; (2) the convectional precipitation process characteristics in Qingdao area in August and September and its associated gusts; (3) the quantative and objective forecasting method of above weather phenomena at fixed time and site.


In this Letter, a new approach of optical tape for high capacity multilayer data storage is proposed. We show that a length of 5 cm and width of 2 cm of soft and transparent optical tape can be used for two-photon three-dimensional bit data storage. We successfully demonstrate writing and reading of six layers of data storage with a transverse bit separation of 2 μm and an axial separation of 2.5 μm in a tetraphenylethylene-doped photobleaching polymer. The fluorescence intensity is insensitive to the storage depth of the photopolymer matrix. Thus, the optical tape that we put forward in the experiment can help people realize true large data storage in the future, like magnetic tape. This method significantly paves a novel way for solving big data storage problems.


To the Editor: I read with interest your recent Editor's Note entitled "Education at the Crossroads: For Today's Practice, the DPT". Even though I have never been in academia, I have had a sincere and abiding interest in the educational preparation of physical therapists. And, at every opportunity, I have seen fit to involve myself in the dialogue of how physical therapists should be prepared to enter practice.

Early in my career, I recognized that something of substance was missing from the manner in which physical therapists were prepared to enter practice, and that no matter how much we tinkered with developing entry-level models, that "something" was still missing. Each of the models advanced through the certificate, baccalaureate, postbaccalaureate, and now the DPT were intended to better prepare the student to effectively deal with the requirements of practice at that point in time.…

The rate of synthesis of different hemoglobin (Hb) species — embryonic, primitive, definitive, and adult — in the circulating red cells of the chick embryo have been measured. On the fifth day of chick embryogenesis, there is a marked decrease in the capability of these red cells to synthesize Hb. The rates of synthesis of embryonic and primitive Hb decrease markedly compared to that of definitive and adult Hb. On the fourth day of embryogenesis nucleic acid synthesis drops sharply in these cells. These decreases in metabolic activity preceed the disappearance of the primitive erythrocyte from the chick embryo circulation. It appears that the primitive cell line is specifically shut off with respect to its metabolic activities and possibly destroyed at this time.

A project on topographic maps interpretation is being driven at I.G.N. (Institut Geographique National, France). The aim of this project is to provide a totally automatic interpretation with a call to operator on the only suspicious cases detected by the program. This paper presents an automatic system for the creation of a Digital Terrain Model (DTM) out of a scanned map. Our proposed method is based on the use of external elevation information and on a combined local/global strategy for quoting the portions of curve present on the map. To reduce the combinatory of the problem, and to accelerate the convergence, all the "trivial cases" of interruption are pretreated. After having quoted the portions of curve, a DTM is created by a classical interpolation method.


Objective To compare the indicators of early embryo development of gonadotropin-releasing hormone antagonist ( GnRH - a ) long protocol with gonadotropin-releasing hormone agonist ( GnRH - A )protocol,to investigate the influence of GnRH analogues upon early embryo development in vitro fertilization - embryo transfer ( IVF-ET ).Methods 100 patients with normal ovarian reserve undergoing IVF-ET were classified into GnRHa group and GnRHA group randomly.Compared the laboratory results and the radio of blastomere number,vacuole,non-symmetry,multinuclear,and fraction of D2,D3 embryo; and compared the radio of transfer-embryo's cell number between pregnancy and nonpregnancy in fresh and frozen embryo transfer ( FET ) of two groups.Results The rates of normal fertility,normal cleavage,available embryo,and high-quality embryo were not significantly different between two groups(P > 0.05).Otherwise,the radios of D2 multinuclear-embryo and D2,D3 fraction-embryo of Group 1 were significantly lower than Group 2; the radios of D2 > 4-cells embryo and D3 8-cells embryo of Group 1 were significantly more than Group 2,which reached statistical difference(P < 0.05).The pregnancy rate in fresh embryo transfer of Group 1 was higher than Group 2,which there was statistical differences between two groups(P< 0.05).No statistical differences were observed on the pregnancy rates in FET between two Groups (P> 0.05).There was no significant differences on implantation rates and the radio of cell number of transfer-embryo between pregnancy and non-pregnancy in fresh embryo transfer of Group 1 (P> 0.05).The number of 8-cells embryo in pregnancy was more than non-pregnancy in Group 2 ; there was significant difference(P< 0.05).Conclusion Early embryonic cleavage of GnRH-A protocol was slower than that of GnRH-A long protocol; and the radios of multinuclear and fraction embryo of GnRH-A protocol were higher than GnRH-A long protocol.8-cells embryo-transfer in fresh and frozen embryo transfer can contribute to increasing pregnancy rate in GnRH-A protocol.

supporting detonation wave is of the pathological type. For such waves the detonation speed is an eigenvalue of the steady equations, and the reaction zone contains an internal frozen sonic point where the thermicity vanishes. The self-supporting flow downstream of this singular point is supersonic, and is very different from that in supported (overdriven) detonations. A method for determining the structure of pathological detonation waves is described. These waves are examined, and the self-sustaining wave is compared with and contrasted to the supported detonations considered previously by Khokhlov. We show that the thickness of the self-sustaining detonation is a few times the thickness of supported detonations, and that the self-sustaining detonation produces more of the iron-peak and less of the intermediate mass elements than do supported detonations. Implications for the cellular detonation instability are also discussed.


: Green Frame is an environmentally friendly column-beam system composed of composite PC members that can increase buildings' life spans while reducing resource consumption. Typically, connections of PC and RC columns occur at the boundaries of each floor, which is at the upper section of slabs, causing the boundary of each floor to generate the maximum moment. Although it is not optimal in terms of structural safety to connect members at a location where the moment is high, this approach is highly adopted due to its constructability. We propose that a superior approach that employs the concept of connecting columns at the low bending moment zone can be applied to quickly and safely install green columns, the main structural members of Green Frame. Connection of green columns at the low bending moment zone can be classified into three techniques, depending on the method of reinforcing the joints, which have different connection characteristics and construction methods. Research is needed to compare the features of each method of reinforcing the joints so that the most appropriate column connection method can be chosen for the site conditions. This study aims to confirm the structural safety of the connection component at the low bending moment zone and to compare and analyze the construction duration, unit price, quality and safety performance of each column connection method. The study results are anticipated to activate the use of composite precast concrete and to be used as development data in the future.

Transl Pediatr 2020;9(6):873-875 | http://dx.doi.org/10.21037/tp-20-151 Recent ly, pediatr ic ians f rom Europe and North America have found that increasing cases of multisystem inflammatory syndrome in children (MIS-C) may be associated with SARS-CoV-2 infection (1-3). It is quite confusing that in Asia where Coronavirus Disease 2019 (COVID-19) first outbroke, cases of MIS-C have been less commonly described. Various speculations have then emerged on this issue, and some even suspected that Asian pediatricians missed the diagnosis of MIS-C in the early epidemic, yet we hold different viewpoints on this issue. In the early epidemic when the published data on COVID-19 in children were limited, most case reports originated from Asia (mainly from China, Figure 1). As early as February 2020, Chinese pediatricians reported the first severe COVID-19 case in children in the world. The patient had prominent gastrointestinal symptoms at onset and rapidly progressed to shock, acute respiratory distress syndrome (ARDS), and kidney failure. We now consider it a suspicious case of MIS-C as the patient had multiple organs involvement (4). Another case series included 171 confirmed cases of children with SARS-CoV-2 infection and only 3 of them required intensive care support and invasive mechanical ventilation (5). All these 3 patients had coexisting conditions and one 10-month-old child died with multiorgan failure. Also, the largest case series on children with COVID-19 was published from China, disclosing detailed symptoms and outcomes of the confirmed cases (6). However, limited number of clustered cases were not enough to conclude the connection with MIS-C. We therefore postulated about the reasons why MIS-C has been less commonly described in Asia. Firstly, it is probably related to the different prevalence rates of COVID-19. Wuhan, the worst affected city by SARS-CoV-2 in China, has an infection rate of around 0.6% and a fatality rate of 7.7%, which was much lower than that of the main European epidemic cities, where the infection rate reached up to 9% (Bergamo, Italy, gathering site of MIS-C cases) and the fatality rate was close to 20% widely. Children cases may account for less than 2% of all cases all over the world, and the association might be found only when the prevalence rate was relatively high. Besides, differences in ethnic or genetic background and SARS-CoV-2 subtypes may lead to different COVID-19 prevalence and incidence of MIS-C, but the relationship between ethnicity and susceptibility of MIS-C was inconclusive. Despite cohorts from Europe and North America have showed high proportion of children of black origin, there were certain amounts of Asian patients (2). During the COVID-19 pandemic, hospitals in China conducted large-scale SARS-CoV-2 screening for patients with fever, especially for those with severe illness. Other Asian countries were likely to have adopted the same strategy, which would be an essential opportunity for catching COVID-19 related syndromes. However, no clustered MIS-C cases like those in the Italian pediatric intensive care unit (PICU) were observed. MIS-C presents Letter to the Editor


This paper studies the impact of a government's efficiency on the taxation policy of a state. Namely, we claim that the countries are different both in the way they tax capital and the way they spend the collected revenue. We build a model of 2 countries competing for foreign investment, government of one of them is more efficient than the other one, which means that it is able to produce more public good out of the same revenue. We show that the country with the more efficient government will charge higher income tax from firms. The theoretical predictions are then tested on a sample of OECD countries, years 1996-2005. In general, empirical results are in line with the theory.

A theory of a grating simulated echo (GTE) is developed. The GSE involves the sequential excitation of atoms by two counterpropagating traveling waves, a standing wave, and a third traveling wave. It is shown that the echo signal is very sensitive to small changes in atomic velocity, much more sensitive than the normal stimulated echo. Use of the GSE as a collisional probe or accelerometer is discussed.


It is necessary to classify the division of the unconformity-bounded stratigraphic unitswhen making lithostratigraphic divisions.An unconformity-bounded stratigraphic unit consists of interealated basic lithographic units-Formation/Group and is confined to the top andbottom unconformity interfaces. In North China stratigraphic area is prelimarily divided into8 unconformity-bounded stratigraphic units, they are Sangganhe, Wutaishan, Hutuohe, Qin-You, Ji-Lu, Sanjin Yan-Liao and He-Hai synthem. The division and estaolishment of the unconformity-bounded stratigraphic units are the premise of the stratigraphic framework analysis and sequence stratigraphic study, and also advantageous to the compilation of smallscaled geological map by using of lithographic units (i. e.unconformity-bounded stratigraphicunits ).


Based on models for drifting sand cover and vegetation cover and dynamical monitors of desertification,an analytical method was proposed for determining the quantity effect of natural factors on sandy pasture desertification.Models for drifting sand cover include the sand transport rate model,threshold wind model and erosion rate model.The model of vegetation cover is featured by consideration of effect of the drifting sand on utilization of precipitation.The application of the method in the pasture desertification in Neman Banner,Inner Mongolia shows good results.It take about 4 or 5 years for the desertified pasture rehabilitating after the human activities stop,if not drought years occur in succession.Natural factors had no contribution to the pasture desertification in Neiman Banner in recent years.

The effects of physical processes on the distribution, speciation, and sources/sinks for Fe in a high-nutrient low-chlorophyll (HNLC) region were assessed during FeCycle, a mesoscale SF6 tracer release during February 2003 (austral summer) to the SE of New Zealand. Physical mixing processes were prevalent during FeCycle with rapid patch growth (strain rate γ = 0.17–0.20 d−1) from a circular shape (50 km2) into a long filament of ∼400 km2 by day 10. Slippage between layers saw the patch-head overlying noninfused waters while the tail was capped by adjacent surface waters resulting in a SF6 maximum at depth. As the patch developed it entrained adjacent waters containing higher chlorophyll concentrations, but similar dissolved iron (DFe) levels, than the initial infused patch. DFe was low ∼60 pmol L−1 in surface waters during FeCycle and was dominated by organic complexation. Nighttime measurements of Fe(II) ∼20 pmol L−1 suggest the presence of Fe(II) organic complexes in the absence of an identifiable fast Fe(III) reduction process. Combining residence times and phytoplankton uptake fluxes for DFe it is cycled through the biota 140–280 times before leaving the winter mixed layer (WML). This strong Fe demand throughout the euphotic zone coupled with the low Fe:NO3 − (11.9 μmol:mol) below the ferricline suggests that vertical diffusion of Fe is insufficient to relieve chronic iron limitation, indicating the importance of atmospheric inputs of Fe to this region.


In the current care scenario of the COVID-19 pandemic, older oncology patients are especially vulnerable and find themselves facing a double threat. On the one hand, the risk of contracting an infection that we still know little about facilitated by immunosuppression and potentially aggravated by the antineoplastic treatment toxicity, co-morbidities, and the cancer severity [1]. On the other, the neoplastic disease itself, along with the risk of losing an opportunity because of the reduction of medical cancer care, due to the limitation or re-allocation of resources [2]. Therefore, one priority aspect is establishing the individual risk associated with the neoplasm and the treatment, in the context of each type of oncological patient [3]. Although cancer is assumed to be an adverse prognostic factor in patients with COVID-19 and in older persons, there is still uncertainty and a lack of robust evidence. Recommendations have surged concerning therapeutic decisions in oncology patients, and the records of cancer patients with COVID. Nevertheless, the real impact of therapeutic decisions in clinical practice remains unknown, especially in the older patient group as well as the evolution of this population group. To increase the available evidence in the current pandemic, we aimed to retrospectively record the management of patients 70 years and older with cancer who received care in the Medical Oncology services of the hospitals belonging to the GIDO group during the early pandemic.


Abstract:This article reassesses the nature and scope of the Melville revival movement in late nineteenth-century Britain and redeems British socialism's role in the reception of Herman Melville on both sides of the Atlantic. In its nascent stage, British socialism sought alternatives to middle-class ideologies, enlarging its scope to encompass not only socio-economic but also humanitarian projects with a belief in the ethical transformation for the individual as a viable force of social change. These socialists, mostly with Fabian connections, such as Robert Buchanan and Henry Salt, were deeply interested in American Romanticism, particularly writers who were unjustly reviewed in their home country, namely Whitman and Thoreau. Melville was also being incorporated into this agenda. Aiming to reach a working-class readership, socialists planned to publish his work under the Walter Scott Publishing Company's Camelot Series. The failure of this project precluded the possibility of their Melville revival reaching fruition, but Melville's distinguished American quality, born out of Young America's antagonistic feelings toward British tradition, provided them with both a means to think outside British middle-class ideologies and a vision of a transatlantic and potentially anti-colonialist literary collaboration.

Wireless systems are getting deployed in many new environments with different antenna heights, frequency bands and multipath conditions. This has led to an increasing demand for more channel measurements to understand wireless propagation in specific environments and assist deployment engineering. We design and implement a rapid wireless channel sounding system, using the Universal Software Radio Peripheral (USRP) and GNU Radio software, to address these demands. Our design measures channel propagation characteristics simultaneously from multiple transmitter locations. The system consists of multiple battery-powered transmitters and receivers. Therefore, we can set-up the channel sounder rapidly at a field location and measure expeditiously by analyzing different transmitters' signals during a single walk or drive through the environment. Our design can be used for both indoor and outdoor channel measurements in the frequency range of 1 MHz to 6 GHz. We expect that the proposed approach, with a few further refinements, can transform the task of propagation measurement as a routine part of day-to-day wireless network engineering.


Based on the environmental protection, this paper proposes the guiding effect of green barriers for the export trade of developing nations. And it has critized the green barriers of Chinese export trade. It also thinks that China has paid a heavy cost for the huge achievement. The negative effect is releasing gradually. Based on the understanding about the complicated and volatile international trade environment and domestic transformation of economy growth, it proposes some suggestions about transforming the developing route of Chinese traditional export trade.


Binder less and additive free sulfur thin film is prepared at room temperature (300 K) first time in literature from simple chemical route. The X-ray diffraction (XRD) study analyzed formation of crystalline orthorhombic sulfur. Scanning electron microscopy (SEM) revealed micro-spheres composed surface morphology. Supercapacitive properties of sulfur thin film are analyzed through cyclic voltammetry (CV) and galvanostatic charge-discharge techniques. Large potential window of 0 to +1.6 V is achieved for sulfur electrode in neutral 1 M LiClO4-propylene carbonate (LiClO4-PC) electrolyte. The highest specific capacitance and specific energy of 25 Fg and 0.48 Whkg is achieved, respectively at 5 mVs scan rate. After 600 consecutive CV cycles of sulfur, 90 % capacitance is retained in PC-LiClO4. An electrochemical impedance measurement shows supercapacitive behavior of sulfur.


Aceh has several religious tourism destinations, especially the historic mosques and the graves of the Ulama but it turns out that many tourists also come and visit Dayah. The flow of tourist arrivals to Dayah has not been well organized, whereas the potential of Dayah as a religious tourism destination is very large to be developed. This study aims to provide an overview of the potential and strategy of Dayah development as one of the religious tourism destinations in Aceh. The research method used in this research is qualitative with observation and interview based on primary and secondary data. The results show that some Dayah in Aceh who have great potential need to be developed as a religious tourism destination. The potential development efforts can be through several strategies that involve the role of government, Ulama and Dayah managers and the Dayah community.


Jimenez remembers his seventh-grade English teacher who cried in front of the class when she reprimanded her students for cheering when a fight broke out between two classmates. He considers the effects of expressing honest emotion with students, of being "real" with them, especially in a year such as the one we've just lived through, where expectations about how things work--including learning--have been shattered. He also wonders about the expression of fragility and encourages us to note how students learn from the models of behavior we offer them when we respond to disappointment, loss, and uncertainty.


A simple and general method for applying the results of a microinstability analysis to models of the solar wind is described. Existing two-fluid models are found to become unstable at heliocentric distances varying from 3 to 11 RS. The development of these 'heat conduction' microinstabilities affects the energy and momentum transport, observable wave spectrum, cosmic ray diffusion, and properties of minor ions in the solar wind. A proposal which would rationally modify the energy transport is developed. It is suggested that the plasma fluctuations observed near the earth could largely be a result of these instabilities. The observed temperatures and velocities of helium ions can be explained qualitatively in terms of resonant interaction with the different waves which are expected to be generated under different solar wind conditions.

Models that have been developed for wheel/rail rolling noise are generally linear in order to make use of a frequency-domain approach. In fact, the local elasticity between the wheel and the rail exhibits a nonlinear stiffness behaviour due to geometrical effects. This is, therefore, usually linearised about a nominal static preload. For large defects on the wheel or rail surface, however, such an approach can no longer be used and a time-domain solution including the non-linearities is required. By using simplified models of the wheel and rail dynamics in such a timestepping model, the effects of the non-linearities have been determined. It has been found that, for normal levels of surface roughness found on wheels and rails, the linear models give a satisfactory prediction. However, for larger defects, such as wheel flats or rail joints, the non-linear effects are found to be significant. A hybrid approach is used to predict the noise radiation due to such defects, for which more detailed dynamic models should be incorporated. The contact force from the nonlinear calculation is converted back to an equivalent roughness that can be used in a linear model for the response and noise radiation.


The Angra 1 nuclear power plant generates electricity from the heat transfer produced in the reactor to two steam generators that activate a turbogenerator. The steam generated condenses in contact with the outer surface of tubular beams of the condenser, where seawater circulates internally, which is captured by the intake tunnel and discharged through a reinforced concrete tunnel where it generates bio-encrustation, increased roughness and prevents inspection. of that structure. The objective of the research was to evaluate the activity of bio-encrustation, the anti-fouling efficacy, bubble formation and adhesion of coatings MC-DUR 2496 CTP from the supplier MC-Bauchemie; PAINTABLE BLUE PLASTEEL, PLASTEEL ANTI CRACA and PLASTEEL HIGH CHEMICAL RESISTANCE from the supplier QUIMATIC / TAPIMATIC; ICOSIT K 101 TW from supplier SIKA and INTERSLEEK 1100 SR from supplier AKZO NOBEL. Six areas were selected for removal and taxonomic classification of bio-encrustation and application of coatings, where it was concluded that bio-encrustation is active and that PLASTEEL AZUL PAINTABLE, ICOSIT K 101 TW and PLASTEEL ANTI CRACA coatings remained adhered to the internal surface of the tunnel although not tested against bio-encrustation in view of the low development speed of the barnacle of the Megabalanus coccopoma species. The coatings MC-DUR 2496 CTP and INTERSLEEK 1100 SR had their performance compromised by bubble formation and delamination while the PLASTEEL HIGH RESISTANCE CHEMICAL coating was completely covered by the gastropod mollusc Petaloconchus varians of the Vermetidae family.


. We study the non-Gaussianities in quasi-single field inflation with a warm inflation background. The thermal effects at small scales can sufficiently enhance the magnitude of the primordial standard clock signal. This scenario offers us the possibility of probing the UV physics of the very early universe without the exponentially small Boltzmann factor when the mass of the isocurvaton is much heavier than Hubble. The thermal effects at small scales can be studied using the flat space thermal field theory, connected to an effective description using non-Bunch-Davies vacuum at large scales, with large clock signal.


Purpose this study was conducted to evaluate the muscular and hormonal responses in elderly males following a program of whole body vibration (WBV) exercise. Subjects Sixty male participants aged from 62 to 75 years were recruited from Hedaya Barakat residential care centre to participate in this study. They divided into two groups: WBV group (n=30) and the control group (n=30). ProcedureWBV exercise was performed at intensity of 12 -20 Hz for duration of 4 minutes, three times weekly, for a total treatment period of eight weeks. Hormonal measurements for testosterone (T) and growth hormone (GH), mechanical measurements for isokinetic plantar and dorsiflexion peak torque, isokinetic knee flexion and extension peak torque were performed. Student's t test for independent samples was used for the statistical analysis, considering p< 0.05 as the statistical significance level. Results hormonal measurements showed significant increase in the plasma concentration of T and GH. The mechanical measurements showed significantly improved isokinetic ankle and knee muscle strength. Conclusion exercise program with WBV in elderly men caused an increased plasma concentrations of T and GH, also improved isokinetic ankle and knee muscle strength. Therefore, WBV training can be a beneficial addition to traditional strength programs in elderly.


In view of the hypothesis of "complete rationality" in classical decision-making theory,Simon proposed the concept of "bounded rationality",but there are many arguments about its reason.This article analyzes the intrinsic reason of "bounded rationality" from a psychological approach: the decision-maker's limitation of sensation and memory ability,the limitation of his attention resource,the thought bias,the mood and so on,which may lead to his bounded rationality."bounded rationality",may be divided into "unable oriented bounded rationality" and "don't want oriented bounded rationality".


Case method education is a learning style that is used to form a basis of comprehensive, hands-on and problem-solving ability, in which the participants discuss teaching such materials of simulated cases, with the requirement that they be judged and deal with the material by themselves, so that they can consider how they should behave in similar circumstances. The objectives of this study are evaluation of the case method education for active and negative participations of university students by group interviews. Method:90minutes case method education was conducted for109Yogo teacher students in4universities. We also conducted interview research with some of the participants selected from4 universities of the education groups after they experienced case method education. Results and Discussions: As a result, it became clear that even negative participants can also learn a lot from this method. However, it was also suggested that where prior study is not fully carried out, this has an effect on negative participation. キーワード:ケースメソッド教育(Case method education) 積極的参加(Active participation) 消極的参加(Negative participation) インタビュー(Interview) 大学生(University student)

The energy efficiency and reliability of electric power systems depends in many respects on the condition of high-voltage transformer equipment. Defective condition of one transformer unit is often the cause of a sudden emergency stoppage of the entire technological chain of an integral production process. To prevent such situations, an efficient technology for monitoring the condition of transformer windings is necessary. Standard methods show poor efficiency in detection of winding defects at their early development stages. An approach to a winding defect diagnosing methodology based on the use of a nanosecond probing pulse with a steep front is proposed. It is shown that by probing the windings with a pulse of 100 ns duration and a front of about 20 ns it is possible to reveal both mechanical and electrical defects. Experiments performed on a power transformer physical model have shown that the proposed method has the necessary sensitivity to minor changes in capacitive elements caused by defects at their initial development stage. It has been established that the nanosecond pulse method sensitivity increases significantly with decreasing the probing pulse duration and increasing its front steepness.

The basic aspects of the endogenous intoxication syndrome (EIS) in the pathogenesis of many diseases are still poorly understood - an increase in the content of a wide variety of compounds, most of which belong to middle mass molecules (MMM) with a mass of 500-2000 D, the content of which under the conditions of metabolically associated steatosis of the liver (MASL) as the initial stage of the fatty disease has not been yet established.
In order to determine the content of molecules of average mass of total and their fractions in the blood and urine in patients with MASL, 25 patients were examined (14 men, 11 women; average age 63,8 years) with coronary artery disease (CAD), atherosclerotic cardiosclerosis, heart failure of I-II FC and sonographically diagnosed fatty liver disease (19 with MACL and 6 with steatohepatitis (SH)), in which MMMs were additionally determined at 238, 254, 266 and 282 nm in blood and urine at 238, 254, 266, 280, 288, 310 nm; coefficients of aromaticity were calculated, peptide-nucleotide, distributive; de Ritis indices and hepato-steatosis, AST/platelet ratio. The results were calculated statistically. The level of significance is p<0,05.
The results. In patients with chronic forms of coronary artery disease, under the conditions of concomitant MASL, the content of total MMM was significantly higher (0,63±0,06 vs 0,34±0,02; p<0,05), which correlated with the level of high-sensitivity C-reactive protein (r=0,86; p<0,05). It was accompanied by the elevation of MMM at all wavelengths in the blood (238, 254, 266, and 280 nm) and hydrophilic chain MMM238 in urine and was associated by significantly higher values of aromaticity coefficients (2,14±0,23 vs 1,60±0,05) and peptide-nucleotide (2,65±0,37 vs 1,38±0,05), all p<0,05. The group with concomitant MASL differed from patients with comorbid SH significantly only in the lower content of hydrophilic MMM238 in urine (1,92±0,18 vs 2,30±0,03; p<0,05).
Conclusion. Metabolic-associated steatosis of the liver is accompanied by the activation of the endogenous intoxication syndrome with an increase of the content of MMM in the blood and urine, which occurs in parallel with the syndrome of systemic inflammation.


This paper represent an asynchronous binary search ADC with reduced comparator counts. The flash ADC needs 2 n -1 comparator to for N bit ADC converter. An original binary search ADC requires 2 n -1 comparators and modified binary search ADC requires 2n-1 comparators while the ADC proposed in the paper only needs N comparators. The purposed ADC is a balance between flash ADC and successive approximation register ADC in term of power and speed. The purposed ADC is better than original binary search ADC and modified binary search ADC in terms of number of comparators.


This paper describes a totally new concept of operating mechanism insensitive to environment for medium voltage cubicles. Moreover its insensibility to the environment, this new range of mechanisms, thanks to the "new" employed materials for this kind of products, presents several advantages concerning the maintenance, the reliability, the operating and the impact on environment.


Senior members of the English Church became involved in cases of bewitchment and dispossession in the later-sixteenth and early-seventeenth centuries. They sought to exonerate the elderly women accused of witchcraft and their involvement led to the disproving of the efficacy of exorcisms performed by puritan ministers. Although a number of bishops intervened in witchcraft cases, this work was most assiduously carried out by Richard Bancroft, the Bishop of London. In doing so, Bancroft came head to head against the Lord Chief Justice of the Common Pleas, Sir Edmund Anderson, and more broadly against judges and justices of the peace who accepted the verity of cases of possessions and accusations of bewitchment. Particular cases therefore reveal themselves as occasions where episcopacy and judiciary clashed. However these should not be read as cases of the Church versus the Law. The Church was part of the law, in terms of contemporary understandings of the origin of divine positive law. However the cases do suggest that cases involving exorcists were opportunities to propagandize against the episcopate and the justice it delivered via the High Commission. Accordingly Bancroft became involved in these cases because they were opportunities for bishops to assert the authority of their order and the High Commission against their opponents' polemic and were a means to articulate the scope of episcopal authority.


Using rapid kinetic techniques, we have determined the kinetics of zero‐trans influx and equilibrium exchange of adenosine, and its uptake and in situ phosphorylation at 25°C in human erythrocytes which were pretreated with 2′‐deoxycoformycin to inhibit deamination of adenosine. Both the Km and Vmax for adenosine transport were about 300 times higher than those for the in situ phosphorylation of adenosine (Km about 0.2 μM), so that the first order rate constants for both processes were about the same. In contrast, the first order rate constant for adenosine deamination by untreated, intact cells was about 20% of that of adenosine transport or phosphorylation. These kinetic properties of the various steps, in combination with substrate inhibition of adenosine phosphorylation above 1 μM adenosine, assure that, at extracellular concentrations of physiological relevance ( < 1 μM), adenosine is very rapidly and efficiently salvaged by the erythrocytes and converted to ATP, whereas at extracellular concentrations of 10 μM or higher, practically all adenosine transported into the cells is deaminated. When the concentration of adenosine was 0.1 μM, a 10% (v/v) suspension of erythrocytes depleted the extracellular fluid of adenosine within 1 min of incubation at 25°C.

This paper describes how the passive climate regulation technique can contribute to achieving good properties in the total telecommunications system in the fields of reliability, power supply, maintenance and economy. The passive climate regulation technique is defined as "Climate regulation without the use of any external source of energy". This is illustrated in the article by a number of applications.


The parameter of concentration of ruptures χ allows to characterize the space distribution of seismogenic ruptures. According to the variations of pressure and temperature at different depths, it is foreseeable that the distribution of these ruptures also varies. It is assumed that the distribution of ruptures is not uniform and corresponds to a fractal space distribution. For the Nest of Bucaramanga the obtained critical values were χ* ≈ 4.1 for shallow seismicity and χ* ≈ 1.9 for the deep one, which indicates a possible influence of the temperature and the pressure in the process of fusion of the cracks at different depths.


This study was a retrospective review to determine the actual results of intramedullary nailing for femur shaft fractures in a trauma hospital. Of 178 consecutive femurs treated with intramedullary nails, 128 fractures could be evaluated at 6 mo. Most fractures were type A. All 128 cases were treated with static interlocking nail. There were 14 (11 %) fractures that did not heal. 50 % of the open fractures and 25 % of the type C fractures did not heal. Opening a fracture to improve reduction was performed 12 times, and all these cases healed without infection.


Acetylated starch as one of the most important modified starches is widely applied in food and non-food processing fields. The impact of ultra high pressure(UHP) on the physicochemical properties of the modified acetylated starch was investigated. Corn starch was substituted with acetic anhydride at pressure range of 300 to 400 MPa for 10 to 20 min. Conventionally prepared acetylated starch(30 ℃,0.1 MP,60 min) was conducted as control. Characteristics of acetylated corn starches in terms of degree of substitution,thermal properties,solubility,swelling power,retrogradation,paste clarity and so on were assessed,and the structure of acetylated starch was charactered by FT-IR. Compared with the conventional method,the UHP processing was favorable for shortening reaction time and increasing the degree of substitution. The degree of substitution reached to the maximum value of 0.0461 at 400 MPa for 20 min,and acetylated starches by using UHP had lower retrogradation.


This study measured the efficiency of use by preschoolers of common input devices including the keyboard, the joystick and the mouse. It also investigated their preferred input device in a free play setting. The manner in which the children interacted with the microcomputers and each other in this setting, including gender factors, was also considered. The subjects in the study consisted of thirty-seven children, of whom fifteen were girls and twenty-two boys, with an average age of four years, seven and a half months. The results indicate that there is a significant difference in efficiency between the three input devices, with the mouse being more efficiently used than the joystick, which in turn is more efficiently used than the keyboard. The between groups interaction of gender with input device is not significant. No pattern of preference was identified for a particular input device. The microcomputers were used extensively during free play, and from the variety of activities available, the boys selected the microcomputer activity significantly more than the girls. The present study demonstrates that unmonitored free-play allows for inequitable access to, and selection of, a microcomputer activity.


The work analyzes the relationships between cooperative association, fair trade and social sectors such as women, youth, indigenous peoples and the territory, deployed by the small producers of the Cooperativa Agraria Cafetalera Pangoa, of the central Amazon region of Peru, as alternative economic strategies to face the marginalization generated by the capitalist market and deepened by the application of market liberalization policies since the 1990s. The analysis allows a debate on the solidarity economic circuits, relating them to the alternative economic strategies and the social and solidarity economy. keywords Producer cooperatives, cooperatives, agricultural markets, agriculture and international trade. jel codes j54, p13, q13, q17.

OBJECTIVE:
To create novel, genetically accurate genetic mouse models of autism and intellectual disability that will allow us to explore molecular, cellular, and circuit-level pathophysiology of these disorders.
 BACKGROUND:
The Shank3 gene encodes a scaffolding protein that anchors multiple elements of the postsynaptic density at central synapses. Human genetic studies have identified mutations and deletions of the SHANK3 gene as a clear genetic cause of autism and intellectual disability. Thus, novel mutant mouse models of autism have been created based on these human mutations. Our studies of such genetic animal models of autism based on Shank3 mutations have led to significant advances in pathophysiology and treatment target identification in this subset of autism.
 DESIGN/METHODS:
We have created multiple different genetic animal models of autism using standard genetic approaches. We describe behavioral, electrophysiological, biochemical, and morphological abnormalities in these mouse models in an effort to understand what is wrong with the brain as a result of these mutations and how this alteration in brain function may be fixed.
 RESULTS:
Genetic animal models based on Shank3 mutations exhibit behavioral abnormalities of relevance ot autism spectrum disorders as well as associated features such as intellectual disability. Electrophysiological studies identify specific alterations in synaptic function that can be targeted to treat behavioral abnormalities in preclinical studies using the very same models. Biochemical analysis of synaptosome and postsynaptic density preparations identify molecular abnormalities that may also be targeted by potential therapeutics.
 CONCLUSIONS:
Shank3 mutations alter synaptic function, plasticity, biochemistry and behaviors. These findings point to potential therapeutic targets for this subset of autism and intellectual disability that can be tested in future studies in preclinical studies that we hope will translate into clinical treatments in the future.

CD34 is a transmembrane protein expressed by vascular endothelial cells and hematopoietic stem/progenitor cells (HSCs),[1][1] but its function has remained obscure. Recently, we observed that in mice, CD34 is highly expressed by committed mast-cell progenitors and their terminally differentiated


Calculations of inclusive cross sections for the production of bottom quarks in proton-proton and proton-antiproton collisions are presented as a function of energy, transverse momentum, rapidity, and pseudorapidity for values of {radical}{ital s} ranging from 100 GeV to 40 TeV. The computations are based on next-to-leading-order matrix elements from perturbative quantum chromodynamics and on the most recently published sets of parton densities. Variations of the behavior of the gluon density in the region of very small {ital x} provide an estimate of the range of theoretical uncertainty. At Superconducting Super Collider energies, results are presented for both the collider configuration {radical}{ital s} =40 TeV and the fixed-target option {radical}{ital s} =200 GeV. Included are calculations of charm-quark inclusive cross sections at {radical}{ital s} =200 GeV and 1.8 TeV.


A grounded electrical source airborne transient electromagnetic (GREATEM) system on an airship enjoys high depth of prospecting and spatial resolution, as well as outstanding detection efficiency and easy flight control. However, the movement and swing of the front-fixed receiving coil can cause severe baseline drift, leading to inferior resistivity image formation. Consequently, the reduction of baseline drift of GREATEM is of vital importance to inversion explanation. To correct the baseline drift, a traditional interpolation method estimates the baseline 'envelope' using the linear interpolation between the calculated start and end points of all cycles, and obtains the corrected signal by subtracting the envelope from the original signal. However, the effectiveness and efficiency of the removal is found to be low. Considering the characteristics of the baseline drift in GREATEM data, this study proposes a wavelet-based method based on multi-resolution analysis. The optimal wavelet basis and decomposition levels are determined through the iterative comparison of trial and error. This application uses the sym8 wavelet with 10 decomposition levels, and obtains the approximation at level-10 as the baseline drift, then gets the corrected signal by removing the estimated baseline drift from the original signal. To examine the performance of our proposed method, we establish a dipping sheet model and calculate the theoretical response. Through simulations, we compare the signal-to-noise ratio, signal distortion, and processing speed of the wavelet-based method and those of the interpolation method. Simulation results show that the wavelet-based method outperforms the interpolation method. We also use field data to evaluate the methods, compare the depth section images of apparent resistivity using the original signal, the interpolation-corrected signal and the wavelet-corrected signal, respectively. The results confirm that our proposed wavelet-based method is an effective, practical method to remove the baseline drift of GREATEM signals and its performance is significantly superior to the interpolation method.

Peanut is one of the most important crops in the world, both for vegetative oil and as a protein source. Biotechnology approaches provide promising ways to increase peanut productivity, either through improved seed quality or stress resistance. These approaches require the identification of genes that control important agronomical traits, the understanding of gene regulation and metabolic pathways, as well as ways of delivering genes or small RNAs into peanut plants. Because of these requirements, extensive studies have focused on peanut functional genomics and biotechnology, and have made great strides during the past decades. This review summarized the advances in peanut omics and biotechnology in China.


Neonatal meningitis is associated with significant mortality and morbidity. Though proteus mirabilis is not frequently encountered as the causative organism in this condition,' it appears to be commonly complicated by cerebral abscess formation.2 Real-time ultrasonography of the neonatal brain has been used extensively in the diagnosis of intraventricular hemorrhage and ventricular enlargement,3 but has less frequently been employed in the evaluation of infants with meningi t i~ .~ .~ We describe a neonate with meningitis due to proteus mirabilis in whom cerebral abscess was diagnosed by real-time ultrasound.


Background: The effectiveness of a dental sealant reimbursement policy for children and adolescents was verified by comparing changes in first molar oral health indicators before and after policy implementation. Methods: Korea National Health and Nutrition Examination Survey data were analyzed: the fourth period (2007–2009) provided data before, and sixth period (2013–2015) data after policy implementation. The proportion of individuals with first-molar sealant, decay-missing-filled first molar permanent teeth, and single crowns in the group aged 11-20 years were calculated. Data were analyzed using chi-square for complex samples and the complex samples general linear model. Results: Compared with non-beneficiaries, among policy beneficiaries, sealant ownership increased by 7.7%, and the number of permanent teeth with sealant per capita was about double; the proportion of individuals with decay-missing-filled permanent teeth decreased 9.1%, and the average decay-missing-filled permanent teeth index per person decreased by about a quarter; the rate of single-crown holders decreased by 2.7%, and the average single-crown index decreased by 0.03 per person. The number of sealants increased with age and household income. The caries rate was higher in females and older respondents. Conclusions: A system is needed to ensure sealant is supplied to vulnerable groups; a follow-up system is required for long-term sealant maintenance.


Background: Effect of cortical mastoidectomy on graft uptake and graft mobility and thence shift of hearing thresholds was analysed in tympanoplasty in discharging ears. Methods: In this study, 60 subjects of safe chronic suppurative otitis media were selected from the outpatient clinics of Dayanand Medical College and Hospital, Ludhiana. All were subjected to tympanoplasty utilizing the underlay technique. Mastoid exploration was undertaken in the ears with persistent ear discharge. Results: Cortical mastoidectomy performed in 20 (33.3%) out of 60 patients and most of cases were done in superiorly based/superior cuff tympanoplasty group in our study. No statistically significance found between cortical mastoidectomy and different flap technique. Mean hearing gain is more with cortical mastoidectomy (16.85 dB) than without cortical mastoidectomy (13.05 dB) and graft uptake was 97.5% without cortical and 95% with cortical mastoidectomy. Conclusions: There was higher mean gain in thresholds of hearing in subjects with cortical mastoidectomy with tympanoplasty though uptake was almost equal to those without mastoidectomy.
