A portable device with cell power supply for field measurement of the electrochemical impedance spectra of coatings and reinforced concrete was designed and developed. This device consisted of a high-speed microcontroller, a direct digital signal synthesizer, a simultaneous dual-channel alternating/direct sampling module and a high-speed analog circuit. To avoid the disturbance of external noise to sampled signals in the presence of high impedance of coating and reinforced concrete system, bi-channel 8-order low-pass filters and pre-amplifiers were integrated in the electric circuit to improve the current resolution. With the help of a fast correlation algorithm and a dedicated design of electromagnetic interference-proof probe,as-developed device was capable of monitoring the quality of coatings and corrosion of reinforced concrete. Based on calculation of the coating resistance, charge transfer resistance and interfacial capacitance, the corrosion status of metals under coating or concrete could be in-situ evaluated. Indoor tests with coated steel sheets showed that the impedance spectra measured with the present device agreed well with those obtained with PAR 273 electrochemical test system.


THE existence of a relationship between the adrenal cortex and the hypertensive state has long been conjectured (Grollman, 1936; Grollman, Harrison and Williams, 1940; Perera, 1950). Despite the many observations suggestive of the existence of such a relationship, the available data fail to support such a view. The recent interest in cortisone and the adrenocorticotrophic hormone of the pituitary (ACTH) has again aroused interest in this problem and led to the trial of these drugs in clinical hypertension. Because of the difficulties and uncertainties involved in evaluating changes observed in the blood pressure of the human subject, the effects of the above-mentioned drugs on the blood pressure in experimental renal hypertension was determined. Rats and dogs rendered hypertensive by application of a figure-of-eight ligature to one kidney and removal of the contralateral one (Grollman, 1944) were injected intramuscularly with cortisone and ACTH.


The utility model provides a water-saving tap with a button for yielding water in a switching way, which comprises a body provided with a water inlet and a water outlet unit; one side surface of the body is provided with a cavity; the inner bottom surface of the cavity is provided with a cavity water inlet; a shell is fixed in the middle of the cavity by a sealing ring; the shell comprises two parts, namely a first shell and a second shell; the bottom part of the first shell is fixed with a gland; the gland is provided with a water passing hole and a central insertion hole; a sleeve-shaped water passing body is arranged in the first shell; the top part of the water passing body is provided with a large flow hole and a small flow hole; a water separating body is arranged in the water passing body in a sliding way and comprises a bottom part extending into the central insertion hole and a top part covering the large flow hole under the action of a reset spring; and a pressing positioning mechanism used for pushing and abutting against the water separating body to separate from the large flow hole is arranged in the second shell. The water-saving tap has simpleness in structure and convenient in operation, and provides a novel switching method.


The theme setting and particular relevance of artificial or man-made famines seems to come up in intervals, when tensions re-arise between 'Western' powers and Russia and seems to be useful for the purposes of 'demonizing' 'Putin'—the current President of the Russian Federation, Vladimir Putin (2000–2008; 2012–)—, 'the Kremlin', the Russian government; or simply 'Russia' in the eyes of 'the West'. In recent years, the famine of 1932–1933 has reached new heights as a politicized event to be instrumentalized in a 'memory war' on many discursive levels (history, mass media, memorialization, etc.) between key-representatives of the current countries Ukraine and Russia (Hordijk 2018). This should, symptomatically, remind us of the sheer power that media narratives have in shaping public imaginations.

The present study starts with the analysis of standard hydraulic cylinder,integrating with practical engineering,demonstrating the usage types of reciprocating seals intuitively,and takes orings,hydraulic lip seals and rectangular-section seals for instance to discuss in detail.Based on the application of seals,three possible states of the lubrication were analyzed,equation of leakage under the hypothesis of infinite line contact theory was listed out,and several factors which influence sealing effect were investigated through carrying out experiments and summarizing experimental results.


Non-small cell lung cancer, if detected at early stage, is a disease with high probability for cure. However, the treatment in clinical practice is highly dependent on the co-morbidities of the patient, the performance status and age. A relevant proportion especially of the elderly patient population remains untreated despite the dismal prognosis of untreated stage I NSCLC with 5 year cancer specific survival (CSS) of only 16% (1,2). Conventionally fractionated radiotherapy has been the treatment of choice for medically inoperable patients: however, outcome is suboptimal with 5 year CSS ranging between 13% and 39% (3); most importantly, local disease recurrence is the most frequent site of failure, not systemic metastases (4). CSS is excellent after lobectomy ranging between 100% and 57.6% depending on the size of the primary tumor (5). Despite a randomized trial demonstrated inferior outcome of sublobar resection compared to lobectomy (6), sublobar resection is practiced especially in high-risk patients aiming at preservation of pulmonary function (7). Wedge resection seems to be insufficient even for small tumors whereas segmentectomy results in promising CSS if the tumor size is below 3cm (5,8).


The study examined the relationship between self-esteem and interpersonal relationships with life expectancy among male students in Dargaz. The study was descriptive and correlational in terms of method. The population was all ninth-gradede male students studying in the academic year 2018-2019 and the sample was 160 students selected by cluster sampling according to Morgan table. The data collection method was field method and data was collected using Snyder's life expectancy questionnaire, Rosenberg Self-Esteem Scale and Matson's Interpersonal Communication Skills Questionnaire given the nature of the subject. Moreover, Pearson correlation and regression analysis were used to confirm or reject the hypotheses. The results showed that self-esteem and interpersonal relationships can significantly predict life expectancy in male students. The results using regression analysis showed that interpersonal relationship predicts 57% and self-esteem 22% life expectancy. Hence, the life expectancy of students can be increased by improving self-esteem and interpersonal relationships.


Potassiumdichromate having strong oxidizing property under acidic condition,can be reduced by many low-cost reducible substances.strong toxicity and great harmful Cr(Ⅵ) is reduced to low toxicity and little harmful Cr(Ⅲ),and converted into Cr(Ⅲ) hydroxid.Based on national standards,experiments of leaching toxicity were carried out,and the Cr(Ⅵ) ion concentration of the lixivium was less than national standards.After stabilizing treatment,secure landfill was performed.


Summary Data have been presented which show that Citrovorum Factor (CF) in a ratio to aminopterin of approximately 16:1, but not of 2:1, counteracts aminopterin inhibition of stilbestrol stimulation of the chick oviduct, while pteroylglutamic acid (PGA) in a ratio to aminopterin of 500:1 is 81% effective in this regard. That CF can substitute for PGA in permitting stilbestrol stimulation of the chick oviduct is further evidence consistent with the theory that CF is a metabolically active form of PGA.


In Monte Carlo simulation, photon transport requires calculating the distance from the location of the photon to the nearest boundary of each uniform attenuating medium along its path of travel, and comparing the distance with the length of its path generated in the simulation. In this paper, we propose a new method which omits the calculation of the location of the exiting point of the photon and of the distance between the exit point and the original position. The method only checks the medium of the voxel existing along with the path of the photon transport. If the medium is different from that in the voxel which the photon emitted, then we calculate the location of the entry point in the voxel, and the length of the path is compared with the mean free path length generated by a random number. Simulations by means of an MCAT phantom show that the ratios of the calculation time were 1.0 for the voxel based method, 0.51 for the proposed method with a 256/spl times/256/spl times/256 matrix image and the effectiveness was confirmed.


The purpose of this study is to investigate the teacher's perception of maker education and to suggest the direction of teacher education curriculum for maker education in order to explore the possibility of applying maker education to early childhood education. To this end, a survey was conducted on the perception of maker education for preschool teachers. As a result of the data analysis, the perception of the concept, meaning, and educational environment of maker education were low, while the effectiveness, importance, value, continuous application and development of maker education were highly recognized and the necessity of maker teacher education and the educational environment was suggested. Based on the survey results, the teacher curriculum composition was classified into basic and advanced courses. The basic course included basic contents to understand maker education and maker space. The advanced course included information on how to use various tools, materials and digital media, how to conduct and evaluate maker education to apply maker education. The teacher curriculum composition for maker education can suggest basic directions for developing teacher education programs and strengthening the digital teaching competency of teachers in the future. ■ keyword :∣Maker Education∣Early Childhood Teacher Curriculum∣Early Childhood Teachers' Perception∣ * 이 논문은 2019학년도 백석대학교 대학연구비에 의하여 수행된 것임 접수일자 : 2019년 10월 04일 수정일자 : 2019년 11월 20일 심사완료일 : 2019년 11월 21일 교신저자 : 이영미, e-mail : email@example.com 한국콘텐츠학회논문지 '20 Vol. 20 No. 1 606


We introduce a remarkably simple coplanar nanostructure consisting of two longer and one shorter graphene nanorods to support a Fano resonance, which arises from the coupling between bright mode and dark mode by breaking the geometrical symmetry. Simulation results, performed with the finite-difference time-domain method, show that the resonant frequency of the bright mode in the transmission spectrum can be independently tuned by changing the lateral offset of the shorter graphene nanorod, while changing its longitudinal offset can independently adjust the resonant frequency of the dark mode. Furthermore, Fano resonance spectrum can also be regulated actively by altering the Fermi energy of graphene as well as refractive index of the surrounding media. This letter proposes a unique modulation strategy of Fano resonance in metamaterials, assisting in developing potential in applications of sensor devices and some other plasmonic functional devices.


The Centers for Disease Control and Prevention (CDC) has been monitoring the prevalence of diagnosed and medicated attention-deficit/hyperactivity disorder (ADHD) among children aged 4 to 17 years since 1997, and the evolving data show rates for both measures have been rising steadily and more dramatically in recent years.


ABSTRACT The paper draws on the architect, J. Max Bond Jr.'s architectural influences in the context of his design response to the Bolgatanga Regional Library, with the aim of advancing the idea of hybrid modernism in postcolonial Ghanaian architecture. Bond considered the Library his first independent work and the most profound. However, as an architect-academic working alongside several celebrated modernist practitioners, Bond's Library appears to have had strong influences. Bond's expression of modernism in the Library reflects the mediation of three cultures: the northern vernacular building culture; the principles of Western modernism; and his hybrid background as an African-American architect. His response, while much like other socio-climatic responses in late tropical practices in Ghana, also demonstrates how the architecture of the marginalised manifested in the use of concrete also constitutes a reflection of the postcolonial mediation of space.


We apply a Bayesian network-based approach for
determining the structure of consumers' brand concept maps, and we
further extend this approach in order to provide a precise
delineation of the set of cognitive variations of that brand
concept map structure which can simultaneously coexist within the
data. This methodology can operate with nonlinear as well as linear
relationships between the variables, and utilizes simple
Likert-style marketing survey data as input. In addition, the
method can operate without any a priori hypothesized structures or
relations among the brand associations in the model. The resulting
brand concept map structures delineate directional (as opposed to
simply correlational) relations among the brand associations, and
differentiates between the predictive and the diagnostic directions
within each link. Further, we determine a Bayesian network-based
link strength measure, and apply it to a comparison of the
strengths of the connections between different semantic categories
of brand association descriptors, as well as between different
strategically important drivers of brand differentiation. Finally,
we apply a precise form of information propagation through the
predictive and diagnostic links within the network in order to
evaluate the effect of introducing new information to the brand
concept network. This overall methodology operates via a
factorization of the joint distribution of the brand association
variables via conditional independence properties and an
application of the causal Markov condition, and as such, it
represents an alternative approach to correlation-based structural
determination methods. By using conditional independence as a core
structural construct, the methods utilized here are especially
well- suited for determining and analyzing asymmetric or
directional beliefs about brand or product attributes. This
methodology builds on the pioneering Brand Concept Mapping approach
of Roedder John et al. (2006). Similar to that approach, the
Bayesian network-based method derives the specific link-by-link
structure among a brand's associations, and also allows for a
precise quantitative determination of the likely effects that
manipulation of specific brand associations will have upon other
strategically important associations within that brand image. In
addition, the method's precise informational semantics and specific
structural measures allow for a greater understanding of the
structure of these brand associations.


Steven Weinstein, M.D., makes house calls as he practices recovery-focused psychiatry with some of Chicago's poorest and most severely mentally ill individuals.


Abstract At the end of 2002, the number of women probationers was substantially higher than the number of women inmates. However, much less is known about women probationers than women inmates. We surveyed and interviewed probation officers to examine their perceptions about the special needs of women probationers and explored officers' experiences with women probationers. Probation officers believe women and men on probation have different needs and therefore require different supervision strategies. Results suggest that the multiple problems and challenges female clients present to their officers, and the greater emotionality they express in their interactions with officers, often place considerable demands on officers' time, energy and skills.


ABSTRACT The effect of aluminium excess on the composition and microstructure of Mo–Al alloys from aluminothermic reduction of metallurgical-grade MoO3 was investigated. Aluminium excess ranged from 0 to 30% (in wt-%) with respect to the stoichiometric amount. The results showed that molybdenum yield increases for higher excess aluminium. The microstructure and composition of the alloys were investigated using scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), and X-ray diffraction (XRD). The following phases were observed in the microstructures: Moss, Mo3Al, and Mo3Al8, besides particles of Al2O3. The results also showed that metallurgical-grade MoO3 leads to a product containing significant amounts of silicon.


Chagas disease is still a specific and impressive problem in Latin America, under many aspects linked to questions related to social inequity and globalization process. The disease, in spite of financial and policies difficulties, has been controlled; however, a period of two or three decades remains necessary for the consolidation of control, surveillance improvement and appropriate therapy for individuals already infected. Since the discovery of Chagas disease, in 1909, the demand for an effective therapy for both stages of the disease, acute and chronic phase, is a challenge for many researchers. Nowadays, only two drugs are being used against Chagas disease, the Nifurtimox and the Benznidazole, known commercially as Lampit ® and Rochagan ®, respectively. This therapy, besides causing several adverse effects, is not effective for the chronic stage of the disease. Currently, several studies report that compounds that have the portion thiosemicarbazone have a potential antichagasic activity due to a possible inhibition of the Trypanosoma cruzi cruzain enzyme (TCC). The cruzain enzyme is responsible for replication of intracellular T. cruzi, and due to this function, it's a target exploited for the development of new drugs potentially antichagasics. The objective of this work was to analyze the synthesis, the studies of "docking" in cruzain and the antichagasic evaluation of thiosemicarbazonics and thiazolinonics derivatives. Initially, aryl-4-oxothiazolilhidrazones were synthesized, resulting in nine different compounds. The obtained products were submitted to in vitro tests of antichagasic activity and to studies of "docking" in the TCC, showing antichagasic activity and TCC interaction. The most promising compound of the group was the N-(4-oxo-5-ethyl-2'tiazolin-2-yl)-N '-phenilthio-(Z)-etilidenehidrazone (6f), which proved to be active in non-cytotoxic concentrations of mammals cells and presented antichagasic activity comparable to that one verified in drugs nowadays, Nifurtimox and Benznidazole. The studies of "docking" revealed that there is an interaction between the compound 6f and the TCC, similarly to that one occurred between benzinidazole binder and the "186". Finally, new Aril-4-Oxothiazolil-hidrazones were synthesized and submitted to review of in vitro antichagasic activity. Fourteen compounds were obtained; the ones that showed the best antichagasics activity were 2 [(p-metilphenilthio-(Z)-etilidene) hydrazone hydrochlorid]-5-methyl-1, 3-thiazol-4 (5H)-one (3f), 2 [(p bromophenilthio-(Z)-etilidene) hydrazone hydrochlorid]-5-ethyl-1 ,3-thiazol-4 (5H)-one (3i) and 2 [(phenilthio-(Z)-3-butilidene) hydrazone hydrochlorid] -1, 3-thiazol-4 (5H)one (3j). The compound 3j, in non-cytotoxic concentration to mammalian cells, presented similar activity to the standards used, the Nifurtimox and the Benznidazole.

Abstract Introduction Delirium is a fluctuating cognitive disorder that occurs in admitted patients, especially in patients who are in intensive care units. Nurses due to persistent contact with patients and direct observation of their mental changes play an essential role in delirium evaluation. Early detection of delirium, identification of risk factors, and its prevention methods are critical to reducing complications, mortality, and treatment costs. This study aimed to determine the perception and the practices of nurses in intensive care units to assess delirium and its barriers. Study design A cross-sectional study. Materials and methods All nurses working in the intensive care unit (neurology, trauma, surgery, general, and heart) of educational hospitals in Kerman, Iran, were the study population. The data gathering tool was a questionnaire consisting of four sections: demographic information, nurses' perception, practices, and perceived barriers in delirium assessment. Results The total score of nurses' perception in delirium assessment was 19.47 ± 3.36, which was higher than the medium score of the questionnaire (estimated score = 16). In all, 45.5% of nurses reported having delirium treatment protocol in their units, and 12.1% of the nurses considered delirium as a priority of evaluating the patient's condition. The most important barrier to delirium assessment was the difficulty of assessing delirium in intubated patients. There was no association between nurses' perception and practices (p value > 0.05). Conclusion Designing and implementing educational programs for improving nurses' practices in this field is necessary. Clinical significance Healthcare providers, especially nurses, should be aware of the delirium assessment of the ICU patients to provide better care.

The invention discloses a color paste pump used for injecting liquid silica gel, which comprises a pump body, a color paste storage device, an air cylinder and a change-over valve, wherein the color paste storage device comprises a color paste cup spliced on the change-over valve; the pump body further comprises a piston rod provided with a seal ring; and the piston rod is connected with the output end of the air cylinder through a piston connector. The color paste pump used for injecting liquid silica gel is characterized in that the air cylinder is also connected with an oil cylinder; the air cavity of the air cylinder is connected with the oil cavity of the oil cylinder through oil pipes; and a hydraulic one-way throttle valve is arranged between the oil pipes. As the hydraulic one-way throttle valve is arranged between the oil pipes, and the piston connector is also connected with a measurement plate, the speed for hydraulic oil to flow into the air cavity of the air cylinder from the oil cavity of the oil cylinder can be controlled by controlling the flow of the one-way throttle valve, so that the upward-motion speed of the piston rod of the color paste pump can be controlled, and the color paste output speed can be controlled. A meter is used for measuring the displacement value of the piston rod motion, and the color paste output speed and the color paste output amount can be known by observing the variation of a meter value.


The Earth Observing System (EOS) is a space-based observing system comprised of a series of satellite sensors by which scientists can monitor the Earth, a Data and Information System (EOSDIS) enabling researchers worldwide to access the satellite data, and an interdisciplinary science research program to interpret the satellite data. In this presentation I will describe the key areas of scientific uncertainty in understanding climate and global change, and follow that with a description of the EOS goals, objectives, and scientific research elements that comprise the program (instrument science teams and interdisciplinary investigations). Finally, I will describe how scientists and policy makers intend to use EOS data to improve our understanding of key global change uncertainties, such as: (i) clouds and radiation, including fossil fuel and natural emissions of sulfate aerosol and its potential impact on cloud feedback, (ii) man's impact on ozone depletion, with examples of ClO and O3 obtained from the UARS satellite during the Austral Spring, and (iii) volcanic eruptions and their impact on climate, with examples from the eruption of Mt. Pinatubo.


EDITOR, - My duties as medical director of Grampian Healthcare NHS Trust, the largest and most diverse trust in Scotland, accord closely with those described by the BMA's committee for public health medicine and community health and include the lead role for disciplinary procedures for medical staff.1 I attend meetings of the trust medical advisory committee as of right but as a non-voting member. The committee's chairperson continues to be elected from among the consultants in the trust.

I firmly believe, however, that to be successful a medical director must have clinical credibility among medical colleagues. This implies a continuing clinical commitment (in my case, four sessions a week in geriatric orthopaedic rehabilitation) and, perhaps more importantly, that the medical director should be appointed from the …


One of the major risk factors triggering or worsening human inflammatory bowel disease (IBD) is the administration of non-steroidal anti-inflammatory drugs (NSAIDs) . Since NSAIDs share inhibition of the enzyme-cyclooxygenase (COX) that catalyzes production of prostanoids, some prostanoids are formed and negatively modulate the extension of IBD. We used mice deficient in prostaglandin (PG) E2 receptor EP1, EP2, EP3, and EP4, and examined the roles of prostaglandin E2 in DSS-induced colitis model. Among the PGE2 receptor-deficient mice, only EP4-deficient mice developed severe colitis with 3% DSS treatment, which induced only marginal colitis in wild-type mice. Conversely, administration of an EP 4-selective agonist (AE 1-734) to wild type mice ameliorated severe colitis normally induced with 7% DSS, while that of an EP 4 agonist, AE 3-208, suppressed recovery from colitis and induced significant proliferation of CD 4+ T cells. In vitro AE 3-208 enhanced and AE 1-734 suppressed the proliferation and Th 1 cytokine production of lamina propria mononuclear cells from the colon. DNA microarray analysis revealed elevated expression of genes associated with immune response and reduced expression of genes with mucosal repair and remodeling in the colon of EP 4-deficient mice. We conclude that EP 4 maintains intestinal homeostasis by keeping mucosal integrity and downregulating immune response.


Objectlve: To assess the image quality and radiation dose of 80 kV electrocardiography(ECG)-gated CCTA in subjects with a normal body mass index(BMI),compared to 120 kV ECG-gated CCTA.Method: The CCTA images of 140 subjects with BMIs 25 kg/m2 were analyzed.Seventy subjects underwent 120 kV CCTA,and the other 70 subjects underwent 80kV CCTA.Two blinded observers independently evaluated the subjective image quality of the coronary arteries.The objective image quality(signal-to-noise ratio(SNR) and contrast-to-noise ratio(CNR)) and radiation dose were also measured in each group.Results: Although the objective image quality of the 80 kV protocol images was significantly poorer than that of 120 kV protocol images(P 0.05),there was no significant difference in the subjective image quality between the two groups(P 0.05).The radiation dose was reduced by 12mSv with the 80 kV protocol and by 82% with the 80 kV and ECG-based tube current modulation than one with the 120 kV protocol(P 0.05).Conclusion: The low tube voltage CCTA protocol using 80 kV allows significant reduction of the radiation dose without impairing the subjective image quality in subjects with normal BMIs.


Twenty-five patients (average age, 65 ± 4.5 years) with spontaneous putaminal hemorrhage were studied to determine any independent predictors as to survival and level of disability. Based on the computed tomography (CT) findings, they were grouped according to their location and extent of the hemorrhage. The thalamus and the caudate were not involved. Univariate and multivariate regression analyses were done to determine any potential prognostic indicator. The groups were significantly different with regard to volume, intraventricular hemorrhage, midline shift, ambient cisterns, hydrocephalus, and disability score but not different with respect to pineal shift, side, gender, and age. The variables that arose as significant predictors of dis ability were intraventricular hemorrhage, midline shift, hydrocephalus, ambient cis terns (all p ≤ 0.001), pineal shift and age (both p ≤ 0.04). Neither gender nor side was a significant predictor for disability score (p = 0.92 and p = 0.125, respectively). Multivariate regression model included volume, ambient cisterns, and age as signifi cant predictors for disability score. Key Words: Putaminal hemorrhage—Intracerebral hemorrhage—Functional recovery—Mortality.


Recent reports indicate that cardiovascular sensory inputs to neurons in the nucleus tractus solitarius (NTS) can be distinguished based on their response to vanilloid‐ or to purinergic‐ agonists, active only on C‐ or A‐δ fibers respectively.

The invention discloses a user collaboration method of joint network coding and channel coding. Each user owns at least one partner user; each user connects the self-information with the information of each partner users in series for forming a longer information sequence; the channel coding is carried out on the sequence, and the coded data is broadcasted, and the network coding is realized; a base station obtains the information of the users by joint iterative decoding according to the original data broadcasted by the users and the data after the joint network coding and channel coding. As the network coding joints information bits of a plurality of partner users together, the collaboration stage of the user collaboration method with joint network coding and channel coding only occupiesone half of timeslot of the traditional space-time coding collaboration proposal, thereby reducing the end-to-end time delay and improving the transmission efficiency.


This paper describes a large-scale, voluntary, and informal project in which physics graduate students at Northeastern University help undergraduates who are taking physics courses. This approach has been of particular benefit to students in the large freshman and sophomore lecture classes. Its appeal is reflected by the high level of participation of both undergraduate and graduate students. On the basis of our experiences at Northeastern University, we also present specific suggestions that could help other departments who may wish to initiate similar programs.


In this article, we argue that Deleuze's philosophy could be understood as anarchistic in a specifically defined meaning. The imperative of immanence of thought, which we explicate mainly through the reading of Deleuze's Spinoza, on the one hand establishes indivisibility between theory and practice and on the other hand paradoxically orders disobedience. We argue for a thought that is immanent, adequate with its inner practice, for thought that cannot be forced. That is the basis on which we combine the reading of Deleuze, Spinoza, Nietzsche and some basic ideas from the contemporary anarchistic movement (Graeber) and the anarchistic tradition (Stirner). We do not try to argue for a certain form of political action. Our goal is to establish a field of thought, that is by its innermost ontological principles anarchistic: practice must be accompanied by its own theory. Adequate thought cannot be forced. This is a necessary condition for each consistent practice-theory.


Research on audio-based music retrieval has primarily concentrated on refining audio features to improve search quality. However, much less work has been done on improving the time efficiency of music audio searches. Representing music audio documents in an indexable format provides a mechanism for achieving efficiency. To address this issue, in this work Exact Locality Sensitive Mapping (ELSM) is suggested to join the concatenated feature sets and soft hash values. On this basis we propose audio-based music indexing techniques, ELSM and Soft Locality Sensitive Hash (SoftLSH) using an optimized Feature Union (FU) set of extracted audio features. Two contributions are made here. First, the principle of similarity-invariance is applied in summarizing audio feature sequences and utilized in training semantic audio representations based on regression. Second, soft hash values are pre-calculated to help locate the searching range more


Rhodium-105 is a 36 hr half-life beta emitter potentially useful for radiotherapy. Previously, the reaction of 105Rh-chloride with a linear tetrathioether ligand resulted in several species. Evaluation of this reaction at the macroscopic level showed that multiple isomers formed depending on the reaction conditions. Radiotracer syntheses for use in potential radiopharmaceuticals require formation of a single species. Various reaction conditions were examined at the macroscopic level to drive the reaction to a single species, evaluating the effects of reducing agent, solvent, temperature, salt concentration, HCl concentration, pH, and reaction time. Product distributions were evaluated by LC-MS, NMR, IR, and x-ray crystallography.


The research discussed in the article involved the performance of tests assessing the effect of a one-time and four-time repair welding thermal cycle on mechanical properties of 18 mm thick butt joints made of toughened steel S1100QL. The tests also involved the determination of mechanical properties of a production joint and joints subjected to mechanical treatment-based repair, involving the use of the MAG method (138) and metallic flux-cored wire STEIN-MEGAFIL 1100 M. It was ascertained that the mechanical properties of the joints subjected to mechanical treatment-based repair were similar to those of the joints subjected to repair welding involving the removal of a defective part using arc-air gouging.


Introduction Bile acid malabsorption (BAM) is accurately diagnosed using a 75selenium taurocholic acid (SeHCAT) scan which also defines treatments patients require. BAM causes chronic, often debilitating symptoms including loose stool, faecal incontinence and abdominal pain. Primary BAM affects 1% of Britons yet is frequently misdiagnosed as IBS. A further 1% have BAM secondary to other conditions. The 2012 NICE DG7 review of SeHCAT included a cost-effectiveness evaluation based on assumptions without supporting evidence. Our aim was to evaluate the cost of delayed diagnosis of BAM. Methods The notes of all patients undergoing SeHCAT scanning in our Trust over a one-year period were reviewed retrospectively. The number of abnormal scans and patient response to treatment were recorded. Costs of additional clinics/tests/procedures performed before the diagnosis of BAM were calculated using NICE costing templates. Results 1.5% of 3860 new patients seen in our gastroenterology clinics between June 2016-May 2017, 19 men and 37 women, median age 58 (range 19–83) were referred for SeHCAT scanning. Of these, 64% were abnormal: 13 demonstrated severe (<5% 7 day SeHCAT retention), 13 moderate (5%–10%), 5 mild (10%–15%) and 5 borderline (15%–20%) BAM. Underlying causes for BAM included cholecystectomy (n=13), chronic unexplained symptoms (n=12), inflammatory bowel disease (n=4), irritable bowel syndrome (n=4), right hemicolectomy for bowel cancer (n=1), diabetes mellitus (n=1) and multiple possible causes (n=1). If SeHCAT scanning was ordered at first consultation (n=11), patients reported 24 months (median) of symptoms (range 6–360) and the mean diagnostic package of care cost was £910.75. If the SeHCAT scan booked 2nd line or later (n=25), patients reported symptoms for 30 months (median, range 0.5–360) and mean diagnostic package of care cost was £1,481.73. However, in these patients 9 additional abnormalities were found: vitamin D deficiency (n=3), diverticulosis (n=2), folate deficiency (n=1), oesophageal dysmotility (n=1), renal cell carcinoma requiring nephrectomy (n=1) and Helicobacter Pylori gastritis (n=1). Following diagnosis, treatment led to reported symptom improvement (n=24), no change/deterioration (n=3), not reported (n=9). Conclusions In our Trust, SeHCAT scanning is enormously underused. Late diagnosis of BAM is associated with markedly increased costs, unnecessary demands for other services and treatment delay for patients. National data on SeHCAT usage suggest that our findings will apply to most other Trusts. More emphasis to ensure early diagnosis of BAM, a frequent, unpleasant and treatable condition would bring the unusual but highly desirable result of significant health benefits while substantially reducing healthcare costs.


Spectral features of sound are believed to be the primary cues for the human perception of spatial sound elevation. It has also been observed that people connect higher frequencies of sound with a higher elevation of the sound source and lower frequencies with lower elevations. The most common approach to creating an acoustic image delivered by headphones is to use Head Related Transfer Functions (HRTFs). Unfortunately, satisfactory perception of elevation can only be achieved with personalized HRTFs which are impractical to measure. This paper describes an alternative method of sound coding for representation of the virtual sound source elevation in an acoustic image. Our method is based on coding particular elevations with sound stimuli which differ in spectral content. Sound stimuli were created by various signal processing techniques (e.g. filtration, modulation). Experiments show that, in certain cases, test subjects were able to perceive up to 60 different elevations in the range of –40° to 90°.

Marital Quality and Cardiovascular Risk in Women During the Menopausal Transition Tracy E. Brown Department of Psychology, BYU Doctor of Philosophy Marital quality is linked to health benefits for men and women. Although women have less risk factors than men for cardiovascular disease prior to menopause, their risk increases substantially after menopause. The purpose of this study was to assess the impact of marital quality and vasomotor symptoms on cardiovascular risk factors including C-reactive protein (CRP) and carotid intima-media thickness (cIMT) in women before, during, and after the menopausal transition. The final sample consisted of 92 married women between the ages of 40 and 60 years. Hypotheses were tested using hierarchical regression and general linear modeling. Results suggest that greater marital quality reduces the negative effect of a lower level of vasomotor symptoms on cIMT but not CRP. Contrary to hypotheses, marital quality did not predict CRP or cIMT and vasomotor symptoms were not correlated with CRP or cIMT. While analyses did not support an interaction between menopausal status and lower marital quality on vasomotor symptoms or CRP, there was limited support for an interaction between menopausal status and lower marital quality on cIMT (p = .057) suggesting that for postmenopausal women higher marital quality is related to lower levels of cIMT. Overall, findings suggest that it is important to consider the impact of psychosocial aspects of a middle aged woman's life (i.e., marital quality) in conjunction with biological stressors when assessing cardiovascular risks in women during the menopausal transition.


The importance of product return has risen in the last two decades as firms face an increased pricing pressure and more stringent environmental regulations. Anecdotal evidence and a few scholarly studies document the importance of product return, but as yet no scale to measure the use of product return practices has emerged. This study using the data from 125 North American manufacturing companies develops a scale for product return practices and tests the influences of several factors on the product return practices. These factors include information quality, manufacturing technology, Just-In-Time (JIT) production, delivery process, cost leadership strategy and supply chain dynamism. The statistical analysis shows that these factors have a significant positive influence on the use of product return practices. Discussion of our findings and future research opportunities are also addressed.

The subject of research in the article is general scientific and special-legal approaches to understanding the functions of law in general and the information function of law in particular; circumstances that characterize the essence of the information function of its content features. The main goal is to justify the need to consider the information function of law as its independent characteristics; to investigate information functions of individual branches of law, their specifics. In the course of the research, the analysis of various theoretical positions existing in the understanding of the essence of the information function of law is made, the necessity of isolating this function as an independent legal phenomenon is substantiated. The author's definition of the content of the information function of law is formulated. It is established that the information function of law is an impact aimed at the implementation of legal information of legal entities, the formation of socially useful stereotypes of citizens' behavior, the regulation of public relations associated with the implementation of a variety of ways to use information, as well as the creation and functioning of information sphere, ensuring the stability of the state-legal system. The existence of specific features in certain branches of law is a condition that allows them to have special functions that are different from the general functions of law.

The invention belongs to the technical field of digital micro-fluidic control, and in particular discloses a digital micro-fluidic chip capable of generating accurate liquid drops. On the basis of a conventional bipolar plate digital micro-fluidic chip, a group of micro driving electrodes is additionally arranged between a conventional square driving electrode and a liquid storage pool electrode at a liquid drop generation part of the conventional chip so as to form a dumbbell-shaped structure, wherein the group of micro driving electrodes is used for generating and splitting liquid drops; parallel side walls are arranged between bipolar plates of the chip and are positioned over the micro driving electrodes; the parallel side walls and upper and lower polar plates of the chip form a micro pipeline through which the liquid drops flow; the inner diameter of the micro pipeline is equal to or smaller than the width of an elongated electrode, so that the liquid drops in the pipeline can be effectively driven by the elongated electrode. By virtue of the chip, the generation accuracy of the liquid drops can be greatly improved; great significance can be achieved for lab and commercial application of the digital micro-fluidic chip.


Objective To investigate the role of CCR1 in the invasion of human hepatecellular carcinoma (HCC) cell line by introduction of exogenous miRNA to silence CCR1 gene expression.Meth- otis Three double-stranded DNA pcDNA6.2-GW/ EmGFP-miR vectors (S1,S2,S3) targeting human CCR1 mRNA and a negative control plasmid (Neg) were constructed,and were transfected into human HCCLM3 cells with high metastatic potentials.Real-time PCR and Western blotting were used to quantify the mRNA and protein levels of CCR1,respectively.Proliferation and invasiveness of transfected HCCLM3 cells were analyzed.Results After transfection,CCR1 mRNA and protein levels of S3 were significantly lower than the other groups.There was no significant difference in cellular growth rate among the 5 groups. The migrating number of HCCLM3 cells transfected with S3 was also significantly decreased as compared with other groups.Conclusion Introduction of exogenous miRNA to HCCLM3 cell line by transfecting with S3 can effectively reduce the CCR1 expression,which can decease the invasiveness of HCCLM3,but had no significant effect on the cellular proliferation.

are a reading society and that reading at our school is exciting. We built a center in the school's front hall that would be seen by everyone who entered. It had a prefabricated fireplace, an oval braided rug, several rocking chairs, small stools, cushions, and a bookshelf holding comic books about Spiderman, paperbacks about Snoopy, the comic section from Sunday's paper, and books with riddles, magic tricks, and the answers to the hundreds of questions children ask about their world. There were cereal boxes holding an enormous number of fun things to read, magazines and books filled with easily duplicated arts and crafts projects. The center, called Read and Rock, held all of the fun kinds of things to read that are not generally found in media centers or the average classroom. It was a place to visit between, during, before, and after classes? anytime someone felt like reading and rocking. It was a moderately popular place, but materials were quickly exhausted and expensive to substitute or replace on our limited budget, so we decided to ask the children to write short stories, books, poetry, or plays on interesting subjects and place them in the center.


Objective To analyze the initial response rate of radiotherapy and chemotherapy,and the influence of different treatment modalities on pmgnnsis of primary non-Hodgkin lymphoma(NHL)of the nascl cavity.Methods From January 1993 to December 2002,70 patients were confirmed by histopathology as NHL,including 52 T cell origin,2 B cell and 16 NK cell.The main radiotherapy portal was set in front of the nose with a spade like protrusion,supplement with a portal next to the ear on one side or both sides.Combined portal in facial cervical area was first used when there was invasion of the oropharynx.The median dose to the nasal cavity wag 54.0 Gy with a range of 336 to 66 Gy,given before or during after radiotherapy or alone,consisted of 2-6 cycles chemotherapy of COP,CHOP or COBDP.Prognostic factors were analyzed with Cox model. Results The local control rates was 12.5%, 66.7% and 74.0% in chemotherapy alone,radiotherapy alone,and chemotherapy plus radiotherapy.The 5-year survival rate Wag 12.5%,50.0% and 62.0%,respectively(P<0.05).Multifaetor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage,but gender,pathology,age and symptoms had little effect on prognosis.Conclusion Chemotherapy plus radiotherapy group achieved a better survival rate than radiotherapy alone.For some NHL patients with good financial condition,APBSCT is a good choice.

Tornado-scale winds tore through the Upper Midwest the weekend of June 5, devastating whole communities without warning, obliterating the town of Spencer, South Dakota. In its aftermath businesses and governors immediately requested millions of dollars in federal disaster assistance. That terrifying storm was similar to another sobering event on June 1, held right on our campus, offering abundant warning - University of Wisconsin-Milwaukee's first conference on welfare reform: "What Have We Learned so Far?" Wisconsin has received inordinately positive national and international publicity for its putatively phenomenal achievements in reducing its welfare rolls, the costs of which never came close to those of that tornado. This issue of Health & Social Work marks two years since the groundbreaking Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (P.L. 104193) was signed by President Clinton, implementing Temporary Assistance to Needy Families (TANF) block grants. This column presents a preliminary assessment of Wisconsin's, and particularly Milwaukee's, experiences with this 1990s version of "new federalism." Reforms, just like tornadoes, hit localities and real people: landlords, grocery stores, frontline social workers, administrators, local officials, neighbors, schools, businesses, and citizens in general. As in every community affected by recent welfare changes, social workers in Wisconsin, and especially Milwaukee, have found themselves coping with unprecedented complexities and frustrations. Having to adjust our mindsets to revere employment as the panacea it is touted to be, many of us struggle, knowing too well the problems with local implementation and therefore the hollowness of its moral messages about work. The changes in welfare provisions for any local community must be seen in context. Wisconsin has a population of about 5 million people, of whom fewer than 7 percent are people of color and not quite 2.5 percent are foreign born. Milwaukee is the largest county in Wisconsin with 959,275 residents; and the city of Milwaukee has a population of 628,088, of whom 36.6 percent are people of color, as are 58.7 percent of the children. Nationally, 20 percent of children are living in poverty, twice the rate of adults. Milwaukee ranks 43rd among the United State's 50 largest cities in child poverty at 38 percent (Annie E. Casey Foundation, 1997). A 1995 labor market study found unemployment in central city Milwaukee at 21.5 percent (University of Wisconsin-Milwaukee, Employment & Training Institute, 1995), whereas unemployment for the city as a whole was 4.8 percent and only 3 percent for the Milwaukee metropolitan area. Statewide unemployment this year reached a 30-year low. Such disparities set the context in which human services are delivered. The mid-to-late 1990s have seen a number of significant changes in Milwaukee County's human services infrastructure. At the end of 1995, the state eliminated general assistance, leaving 5,500 adults in Milwaukee County with no visible means of support. In 1996, after operating it for three-quarters of a century, Milwaukee closed its only public hospital, transferring care and an annual county subsidy of about $60 million in 1996 and 1997 to the adjacent private Froederdt Hospital. In late 1997 the county devised a plan to disperse about $30 million worth of care through the General Assistance Medical Program (GAMP) throughout the county. GAMP-eligible consumers, who must be sick and have incomes of less than $800 per month, must now register with one of 12 community-based clinics, five of which are sites for the homeless, each supported by a different hospital. In addition, in 1995 the county closed its major inpatient mental health complex, contracting out the bulk of care to several outstationed Community Support Teams. And in 1996, in response to a lawsuit by the American Civil Liberties Union, the state passed legislation to turn over operation of the Milwaukee County child welfare system to the state Department of Health and Family Services in January 1998. …


The purpose of this study was to explore the clinical efficacy and safety of posterior pedicle screw fixation in the treatment of thoracolumbar burst fracture. A total of 120 patients with thoracolumbar burst fractures were selected from January 2014 to December 2016. 60 patients were divided into the study group, and 60 patients were as the control group. The patients in the study group were treated with posterior pedicle screw fixation. The control group was treated with posterior non-traumatic pedicle screw fixation. After treatment, there were six months follow up. The clinical indexes, complications, and the anterior aspect height ratio, the Cobb angle, and the numeric rating scales (NRS) score were compared between the two groups at one month, six months after the operation. Results were I incisions healed into two groups, and no infection occurred after the operation. The operation time of the study group was higher than that of the control group (p<0.05), and there was no statistical difference in the amount of bleeding and the length of stay between the two groups (p>0.05). At one month and six months after the operation, the anterior vertebral height of the two groups was significantly higher than before, and the Cobb angle and NRS score were substantially lower than those before surgery, the difference was statistically significant (p<0.05). The height of the leading edge of the injured vertebra was higher than that of the control group at six months after the operation. However, the difference was not statistically significant (p>0.05). Moreover, the angle of Cobb and the NRS score were lower than those of the control group (p<0.05). The occurrence of postoperative low back pain and biomechanical fixation failure in the study group were significantly lower than those in the control group (p<0.05). To conclude, through the posterior approach, the pedicle screw fixation can efficiently prevent kyphosis, correct the loss and reduce the postoperative complications. It is a useful method for the treatment of thoracolumbar burst fractures.


In 4 years, 200 patients were admitted to the University of Maiduguri Teaching Hospital, in the Northern Savannah of Nigeria, with a clinical diagnosis of peptic ulcer; 60 had the diagnosis of duodenal ulcer confirmed on barium meal or at operation, giving an incidence of 6/1000 adult admissions (excluding obstetrics). There were no gastric ulcers. Forty-four patients had a 'simple ulcer', 10 presented with gastric outlet obstruction, five with peritonitis following perforation and one with haematemesis. There were 44 males, and 16 females, with a mean age of 34 years and mean length of history of 44 months. Contrary to previous published reports improved diagnostic facilities have shown duodenal ulcer to be relatively common in the Northern Savannah of West Africa.


Backward induction is the most widely accepted principle for predicting behavior in dynamic games. In centipede game experiments, however, players frequently violate this principle. An alternative is a"dynamic level-k" model, where players choose a rule from a rule hierarchy. The rule hierarchy is iteratively defined such that the level-k rule is a best-response to the level-(k − 1) rule and the level-∞ rule corresponds to backward induction. Players choose rules based on their best guesses of others' rules and use historical plays to improve their guesses. The model captures two systematic violations of backward induction in centipede games, limited induction and repetition unraveling. Since the dynamic level-k model always converges to backward induction over repetition, the former can be considered as a tracing procedure for the latter. We also investigate whether the same dynamic level-k model can be applied to explaining violations of backward induction in sequential bargaining games and show that the model has some promise in doing so.


We have examined effects of horse serum (HS) and various fractions (1 million‐1M, 300K, 100K, and 30K nominal molecular weight limit) obtained by ultrafiltration on expression of TTX‐sensitive Na‐channels and on activities of the Na‐K pump and glucose transport systems in cultured myotubes obtained from 1‐2‐day‐old neonatal rat pups. Five‐day‐old cells were transferred to serum‐free medium with no hormone or growth factor supplements (DMEM) for 24 hr and then treated with the various serum fractions for 48 hr. Measurements were made of specific [3H]‐saxitoxin (STX) binding, action potential properties, 86Rb‐uptake and 2‐deoxyglucose (2‐DG) uptake. HS significantly increased all parameters compared to DMEM (increases in STX‐binding, 69%; Rb‐uptake, 65%; 2‐DG uptake, 93%). Results of treatment with the separate fractions showed that the 300K fraction caused a significantly greater increase in STX‐binding than either HS or the other fractions. In contrast, the increases in Rb and 2‐DG uptakes induced by the different fractions were not different from that obtained with HS. We conclude that serum contains a factor that selectively increases expression of TTX‐sensitive Na‐channels in skeletal muscle.


Effect of drought stress on physiological-biochemical and ornamental characteristics changes of Tianpeng Tree Peony was studied for key technology of breeding and planting.With potted Paeonia suffruticosa 'Hongdan Lan' as material,the treatment was artificially controlled by weighting and setting four levels,such as control level,light drought stress level,middle drought stress level,heavy drought stress level.The physiological-biochemical indexes of leaves and ornamental characteristics were tested at bud-flaw stage,primary flowering stage,blooming stage,withering stage,late flowering stageⅠand late flowering stageⅡ.The results showed that with intensity of drought stress increased and the duration extended,the content of proline,soluble sugar and soluble protein presented a consistent variation trend of increasing and florescence was longer;while the content of RWC declined,the size of flower was smaller.Meanwhile,drought stress had a significant effect on anthocyanin content of petal(LSCKMSHS).In general,Tianpeng Tree Peony had strong drought resistance,all indicators were sensitive to moderate and hard stress.Appropriate water management could improve the ornamental value of Tianpeng Tree Peony.


Aeromonas hydrophila is quotidian waterborne microorganisms that is often enlaced as a causative agent of clinical infections and has been isolated from animal and plant based food products [1]. It is gram-negative, facultative anaerobe, non-spore forming, rodshaped motile, catalase, oxidase and positive. The genus is made up of psychrophiles and mesophiles. A. hydrophila is frequently known to cause human infections such as septicemia, gastroenteritis and cellulitis, wound sepsis with necrosis, gangrene, pneumonia and traveler's diarrhea resulting from improper handling and consumption of contaminated food [2]. Aeromonas presently is considered as food-borne pathogen of emerging importance and is not listed in the Contaminant Candidate List of food. It has gained attention for potential to grow at refrigeration temperature, association with salad vegetables, assistance of antibiotic resistance and the capability to persist safety treatments in food [3]. Virulence gene detection is important to determine the potential pathogenicity of Aeromonas [4] due to the involvement of pathogenic genes and extracellular proteins including enterotoxin, hemolysin, aerolysin, various hydrolytic International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 11 (2017) pp. 693-707 Journal homepage: http://www.ijcmas.com

The paper illustrates a software architecture allowing a robot to socially interact with human beings, sharing with them some basilar cognitive mechanisms. Robust sensing of the environment and people is strongly linked with an artificial somatosensory system that drives the robot behavior at a low level and influences its motivation. Both long-term memory and short-term memory store relevant data to detect and recognize the social context (and social practice), and the human social behavior. Using both internal and external evaluations, the robot learns and improves its social skills, which take into account its physiological and emotional demands (affiliation, competence, certainty). Social interaction is encoded in the cognitive architecture by considering at the same level the human understanding and the robot communicative actions. This is done by using the same interaction channels (both verbal and nonverbal). Some examples derived from previous works show the effectiveness and the potential of the cognitive architecture.


Meldrum's acid has turned out to be a useful ketene equivalent when faced to nitrone dipoles to form various isoxazolidin-5-one derivatives under very mild Bronsted base organocatalytic conditions. The first asymmetric version of this original domino anionic formal [3+2] cycloaddition–decarboxylation reaction was demonstrated by means of quinine-based organocatalysts.


This article focuses on tracheotomy, which is transformation of language, norms and speech. The article examines the philosophical problem of the transformation of language info speech, the latter is single unbroken wholeness. Norms are previously divided into d ialect and literal. Each of them is in turn d ivided into phonetic, lexical, orthographical, spelling, morphological, syntactic variety. For the disclosure of the issue there are different in terms of foreign and domestic linguistic differentiation with respect to language the language and speech rate. Particular attention is paid to the analysis of the norm in-depth by the well-known Uzbek linguists.


The author analyzes the institute of negligent joint causing harm, which involves joint actions (omission) of two or more persons that resulted in single socially dangerous consequences or created a real threat of their occurrence by negligence. The public danger of this institute is caused by the fact that such encroachments are complicated by objective indicators of their execution, that often causes deaths, infliction of harm to people's health, property destruction (the growth of such crimes is due to the increase of technical equipment of all spheres of human activity and degree of impact on the environment). Moreover, the dissemination of negligent joint causing harm within the existing criminal law is large enough to talk about a special legislative regulation of the limits of liability for this type of socially dangerous acts in the General part of the RF Criminal Code. It's argued that the absence of special rules leads to incorrect qualification. As a result, not all accomplices are brought to liability or the persons having no direct relation to the committed act are wrongly convicted. Legislative consolidation of the analyzed institute is proposed: "the crime is considered committed by negligent joint causing harm if joint actions (omission) of two or more persons being the subjects of crime resulted in single socially dangerous consequences or there was a real threat of their occurrence by negligence". Being legislatively fixed, this institute will serve as one of the grounds for bringing persons obliged to observe established rules and requirements by nature of their activities to liability for criminal behaviour.


Fruit Effect on Photosynthesis and Respiration

Several investigations about fruit effects on photosynthesis and respiration, mainly of Citrus madurensis (Lour.) and Solanum melongena (L) plants are reviewed.

Fruiting plants had higher photosynthetic rates (mg CO2 · dm−2 · h−1) than non fruiting ones, particularly during stages of most intensive fruit growth. The photosynthetic rates could be stimulated by increasing fruit temperatures.

No differences in dark respiration rates of fruiting and non fruiting plants were observed. However photorespiration was considerably higher in non fruiting plants as compared to fruiting ones. Leaves of non fruiting plants accumulated more sugars and starch in the leaves during the light periods than fruiting ones.

The gaseous diffusive resistance of leaves was higher in non fruiting as compared to fruiting ones.

The higher photosynthetic efficiency of fruiting plants is probably controlled by several mechanisms, some of which were discussed in the paper.

This paper presents flux and speed estimation with on-line rotor time constant estimation for an indirect field oriented induction motor drive system using sliding mode technique. A closed loop flux observer based on the current estimation error is constructed. A unique feature of the proposed observer is that, the proposed current observer includes a sliding mode function, which is derivative of the flux. Therefore, when the estimated current converges to the measured one, the sliding mode function is integrated to calculate the flux. The speed and rotor time constant can then be calculated from the sliding mode function and the estimated flux. Simulation and experimental results for the flux and speed estimation of the machine are presented to validate the proposed algorithm.


Summary: A group of 54 patients suffering from chronic lymphatic leukaemia has been analysed for the correlation of clinical and haematological data in relation to immunoglobulin levels.

Not one patient in this series had a normal immunoglobulin pattern, the majority revealed severe reductions of IgA and IgM immunoglobulin levels. The low immunoglobulin levels were associated with higher blood lymphocyte counts, presence of lymphadenopathy and hepatosplenomegaly. With increasing disease duration the immunoglobulins tended to be lower and this was accentuated in the patients receiving treatment. Low levels of immunoglobulin had a high correlation with incidence of infection and death due to infection.

These findings are consistent with the thesis that chronic lymphatic leukaemia is a manifestation of an accumulation of immunologically incompetent cells.


Elevation of cell wall invertase activity by silencing its inhibitor improves tomato fruit set under moderate heat stress via suppressing programmed cell death in a ROS-independent manner. Reduced cell wall invertase (CWIN) activity has been shown to be associated with poor seed and fruit set under abiotic stress. Here, we examined whether genetically increasing native CWIN activity would sustain fruit set under long-term moderate heat stress (LMHS), an important factor limiting crop production, by using transgenic tomato (Solanum lycopersicum) with its CWIN inhibitor gene silenced and focusing on ovaries and fruits at 2 d before and after pollination, respectively. We found that the increase of CWIN activity suppressed LMHS-induced programmed cell death in fruits. Surprisingly, measurement of the contents of H2O2 and malondialdehyde and the activities of a cohort of antioxidant enzymes revealed that the CWIN-mediated inhibition on programmed cell death is exerted in a reactive oxygen species-independent manner. Elevation of CWIN activity sustained Suc import into fruits and increased activities of hexokinase and fructokinase in the ovaries in response to LMHS. Compared to the wild type, the CWIN-elevated transgenic plants exhibited higher transcript levels of heat shock protein genes Hsp90 and Hsp100 in ovaries and HspII17.6 in fruits under LMHS, which corresponded to a lower transcript level of a negative auxin responsive factor IAA9 but a higher expression of the auxin biosynthesis gene ToFZY6 in fruits at 2 d after pollination. Collectively, the data indicate that CWIN enhances fruit set under LMHS through suppression of programmed cell death in a reactive oxygen species-independent manner that could involve enhanced Suc import and catabolism, HSP expression, and auxin response and biosynthesis.


In this work, we propose an approach for extrinsic sensor calibration from per-sensor ego-motion estimates. Our problem formulation is based on dual quaternions, enabling two different online capable solving approaches. We provide a certifiable globally optimal and a fast local approach along with a method to verify the globality of the local approach. Additionally, means for integrating previous knowledge, for example, a common ground plane for planar sensor motion, are described. Our algorithms are evaluated on simulated data and on a publicly available dataset containing RGB-D camera images. Further, our online calibration approach is tested on the KITTI odometry dataset, which provides data of a lidar and two stereo camera systems mounted on a vehicle. Our evaluation confirms the short run time, state-of-the-art accuracy, as well as online capability of our approach while retaining the global optimality of the solution at any time.


This study analyzed the effects of internet fashion consumer`s anticipated regret and the selection difficulty on decision making delay and purchase switching intention. The survey was conducted in 2012 on internet fashion consumers in their 20s to 40s from May 1 to June 30; subsequently, 487 responses were used for the data analysis. The anticipated regret of internet fashion consumers was composed of product, service, social psychology, and function-related anticipated regret. The selection difficulty of internet fashion consumers was composed of process, information, and experience-related selection difficulty. There are significant differences in anticipated regret, selection difficulty, decision making delay, and purchase switching intention by gender. The anticipated regret (product, service, and social psychology-related anticipated regret) and selection difficulty effected decision making delay. In addition, the anticipated regret for product and selection difficulty by process or information influenced purchase switching intention. The results of this study provide useful information on the success and efficient operation of internet shopping malls.


Ofranergene obadenovec (VB-111) is a targeted anti-cancer viral based gene therapy with a dual mechanism: a broad antiangiogenic effect and induction of a tumor directed immune response. Previous study demonstrated a survival benefit for patients with recurrent glioblastoma (rGBM) treated with VB-111 monotherapy that was continued upon progression with combination treatment of VB-111 and bevacizumab. Glioblastoma is an immunologically "cold" microenvironment which fosters immunosuppression and antagonizes anti-tumor immune responses. The role of T-cell infiltration in combating cancer has been increasingly recognized and associated with improved participant outcomes. Based on these observations, this study will assess the hypothesis that neoadjuvant use of VB-111 will lead to a statistically significant increase in tumor infiltrating T lymphocyte (TIL) density within the tumor and enhanced systemic tumor-specific T cell responses.

 This is a multicenter, randomized, blinded, placebo-controlled, phase 2 surgical trial to evaluate early immunologic pharmacodynamic parameters for the viral cancer therapy VB-111 in rGBM. 45 participants with rGBM indicated for resection will randomized to one of three treatment arms: Neoadjuvant Arm: intravenous VB-111 prior to resection, and VB-111 every 6 weeks after resection. Adjuvant Arm: placebo prior to resection, and VB-111 every 6 weeks afterwards. The control arm will receive placebo prior to resection followed by standard of care. Upon evidence of contrast-enhancing progression, bevacizumab may be initiated as needed for supportive care and VB-111 will continue until progression is supported at two consecutive time points. Tumor samples will be obtained and archived at the time of surgery, and blood samples will be obtained as pharmacodynamic markers throughout the study to allow DNA sequencing of T cells. The primary endpoint is influence of neoadjuvant VB-111 on TIL density. Other endpoints include safety and tolerability, peripheral T cell response, tumor/microenvironment transcriptomic alteration, and PFS/OS. Study will open for enrolment in 2019.


This voltage source is designed to bias superconducting tunnel junctions when studying their current-voltage characteristics at voltages ranging from zero to several millivolts. The source has been used in experiments with junctions, whose resistances ranged from 10{sup -2} to 10{sup 3}{Omega}, breakdown voltages from 0. 1 to 10 V, and maximum dissipated powers, from 0.1 to 100 mW. The device allows the current and voltage to be measured across circuit components with resistances under 100 {Omega} to within 0.1%.


Abstract : Genetic algorithms are computational techniques which, given an optimization problem, use elements of directed and stochastic search to find the 'best' solution from the space of potential solutions. We apply GA's to the problem of fitting the minimum least-squares piecewise linear function to a set of data points in R(2) . We assume that the number of pieces is known but the knot locations are unknown. The effectiveness of our algorithm is demonstrated with two examples. Results are found to be quite promising and encourage further research.


At the initial visit, the proportion classified is shown below. As can be seen, the proportion of patients classified as Derangement is encouragingly high, despite the fact that more than 40% of the patients had a history of greater than three months. (Note: the 'Irreducible Derangements' (now known as Mechanically Unresponsive Radiculopathies) found in the study are included in the OTHER category).


This Letter presents a search for quantum black-hole production using 20.3 inverse fb of data collected with the ATLAS detector in pp collisions at the LHC at sqrt(s) = 8 TeV. The quantum black holes are assumed to decay into a lepton (electron or muon) and a jet. In either channel, no event with a lepton-jet invariant mass of 3.5 TeV or more is observed, consistent with the expected background. Limits are set on the product of cross sections and branching fractions for the lepton+jet final states of quantum black holes produced in a search region for invariant masses above 1 TeV. The combined 95% confidence level upper limit on this product for quantum black holes with threshold mass above 3.5 TeV is 0.18 fb. This limit constrains the threshold quantum black-hole mass to be above 5.3 TeV in the model considered.


With the rapid rise of mobile E-business, real time booking service by cell phone is facing great chances and challenges. General method of using J2ME or MFC to develop mobile software can't meet the fast and real time requirements of mobile booking service. In this paper, we propose a new WTL-based method to realize instant booking function by cell phone on mobile network. On the basis of the server of the railway ticketing system, we realize the real time mobile booking system on windows mobile platform. Experiment results show that when booking train tickets by this system, average network access time is only 1.894s, and average query time is only 4.157s. It is testified that this method can greatly shorten the booking query time and other relevant time factors when comparing with traditional method of J2ME or MFC.


Tetrapyrrole-dependent photodynamic herbicides (TDPH)* (Rebeiz et al., 1984) are compounds which force green plants to accumulate undesirable amounts of metabolic intermediates of the chlorophyll (Chl) and heme metabolic pathways, namely tetrapyrroles. In the light the accumulated tetrapyrroles photosensitize the formation of singlet oxygen which kills the treated plants by oxidation of their cellular membranes. Tetrapyrrole-dependent photodynamic herbicides usually consist of a 5-carbon amino acid, 6-aminolevulinic acid (ALA), the precursor of all tetrapyrroles in plant and animals cells, and one of several chemicals referred to as modulators. 6-Aminolevulinic acid and the modulators act in concert. The amino acid serves as a building block of tetrapyrrole accumulation, while the modulator alters quantitatively and qualitatively the pattern of tetrapyrrole accumulation. The tetrapyrroledependent connotation is meant to differentiate between this class of photodynamic herbicides and other light activated herbicides such as paraquat which are not dependent on tetrapyrrole metabolism for herbicidal activity. During the past 6 years, the scope of TDPH research has expanded considerably, as some established herbicides and a plethora of new compounds which act via the TDPH phenomenon have been discovered. In this review an attempt is made to describe this new field of research and to summarize the progress achieved since the field was last reviewed (Rebeiz et al., 1987, 1988a).

This study examined the implementation of artificial neural network (ANN) for the prediction and modeling of methylene blue (MB) and methyl orange (MO) dyes decolorization in aqueous solution using Sn/Zn-TiO2 nanoparticles prepared by sol–gel method. Operational parameters such as amount of catalyst, concentration of dye, reaction time, and temperature of solution were employed as inputs to the network and dye decolorization efficiency was the output of the network. ANN predicted results are in good agreement with the experimental results data with a correlation coefficient (R2) of 0.9839 and 0.9887 for MB and MO dyes, respectively. The sensitivity analysis investigated that studied parameters have different effect on dyes decolorization. For both dyes, reaction time is the most influential parameter and the temperature of solution is the less influential variable in the removal efficiency of both dyes. The results indicated that neural network modeling could effectively predict and model the photocatalyt...

Abstract Dance/movement therapy (DMT) was integrated into mathematics and social-emotional skill instruction for seventh-grade students diagnosed with learning disabilities, emotional/behavioral disabilities, and attention-deficit/hyperactivity disorder. Students who participated in these integrated activities over a 1-month period demonstrated improved performance in mathematics, dance arts, and social-emotional dimensions of learning such as motivation, engagement, attention, and self-regulation. Implications for teaching and learning with special populations are discussed.


Web 2.0 technologies have provided both opportunities and challenges for academic libraries. These sociotechnological innovations have enabled interactivity and gathering of knowledge through experience and practice on a global scale. The concept of collaborative work, social networking and the ease in the usage of these applications has brought a significant change in the internet usage by university students. Many academic libraries are beginning to leverage the power of these services to provide better and more relevant services to their patrons. The use of web 2.0 tools in academic libraries and has begun to take shape recently in Zimbabwe. However, studies reveal that utilisation these tools is still low in Zimbabwean academic libraries. Understanding knowledge, attitudes and practices of university students on web 2.0 tools paves the way for the efficient and effective use of these tools in Zimbabwean libraries. This study aimed at determining the knowledge, attitudes and practices of university students on web 2.0 tools. The survey method was used to gather data. A self administered questionnaire was used to gather data from 280 undergraduate students who were conveniently selected to participate in the study. The findings reveal that most students have excellent knowledge of specific web 2.0 tools such as Instant Messaging and Social networking. Most tools were used mainly for communication purposes. A small percentage of respondents indicated that they use the tools for educational purposes. Students displayed lack of knowledge and use on mashups, social bookmarks, and relatively simple syndication (RSS) feeds. The fact that most of these tools are already being widely used by students entail that academic libraries can utilise these technologies in developing user services. However, the issues of awareness, access, confidentiality, and accuracy of these tools need to be addressed to ensure their successful implementation and use.


ABSTRACTWhen an anomaly is diagnosed in one fetus in a multifetal pregnancy, parents can be offered the choice of selective termination of the anomalous fetus. In dizygotic twins, fetal intracardiac injection of potassium chloride (KCI) is the preferred method. Technically, it can be performed in all three trimesters with good outcome in > 90% of cases. In monochorionic twins, KCI injection is precluded owing to the possible vascular communications between the fetuses. Selective termination in these cases can be performed by occluding the cord of the target fetus, using either cord ligation, laser coagulation or bipolar coagulation.


Introduction: Obesity is an increasing health problem in the whole world, and it has an important inflammatory component related to the insulin resistance (IR), hypertension, atherosclerosis and some cancers. This study aims to evaluate the inflammatory hematological parameters in childhood obesity.Methods: Sixty-four obese and 50 normal weight cases were included in the study. The physical examination features and laboratory data of the patients were evaluated retrospectively from the patient's files. Laboratory tests, hematological parameters, gender were compared between the groups. Correlations between Homeostasis model evaluation for insulin resistance (HOMA-IR) and other laboratory parameters in the obese group were examined.Results: The leukocyte, neutrophile, monocyte, lymphocyte, thrombocyte and MPV values of the obese group were found to be statistically higher than the control group (p: 0.006, p:0.015, p:0.014, p:0.001, p<0.001). There was no statistically significant difference between the two groups for Neutrophile/Lymphocyte ratio (NLR), Monocyte/Lymphocyte ratio (MLR) and Platelet/Lymphocyte ratio (PLR) (p:0.642, p:0.989, 0.982). Also, there was no statistically significant correlation between Homa IR and age, BMI, Neutrophil, Lymphocyte, Monocyte, Thrombocyte, Neutrophil/Lymphocyte, Monocyte/Lymphocyte and Thrombocyte/Lymphocyte values.Conclusion: The current study showed that there was no significant difference between obese and controls in terms of NLR, PLR, and MLR values. However, the leukocyte, neutrophile, monocyte, lymphocyte, thrombocyte and MPV values were statistically higher in obese group than controls. Nevertheless, these findings can point relation between obesity and inflammation.Keywords: obesity, children, inflammation, hematological parameters


A floating-gate erasable programmable read-only memory (EPROM) cell with a thin trench-gate-oxide (TGO) structure near the drain region was fabricated using electron-beam lithography technology. Several promising advantages were found for the TGO cell. The writing time was measured to be 100 faster than conventional devices of the same dimensions. Two-dimensional (2-D) simulation of the TGO structure indicated that longitudinal and transverse channel electric fields are generated which simultaneously increase the hot-electron population in the channel and the injection efficiency into the floating gate. The devices exhibit high-transconductance, fast programming, good-tolerance to unintentional writing during readout, and potential for flash-erase application.<<ETX>>


In recent times, interest in the use of medicinal plants (ethnomedicine or ethnobotanical medicine) as alternative to modern medicines is increasing globally, especially in developing countries where traditional beliefs and high cost of, or limited access to conventional medical treatment may constitute important factors. The use of Sarcocephalus latifolius for the control of various illnesses, especially in West Africa, is widely documented. This study therefore, was designed to highlight the protective potential of Sarcocephalus latifolius fruit extract on body organs such as the liver and kidney by monitoring some biochemical parameters. The plant material was collected from Kadale village in Gwaram Local Government Area of Jigawa State, Nigeria. it was extracted with aq. methanol in a Soxhlet extractor. Acute toxicity examination was carried out on the extract in line with standard methods with the lethal dose obtained to be above 2000mg/kg body weight. The percentage protection of the fruit of S. latifolius on CCl 4  induced toxicity was dose dependent. TLC examination of the column fractions (Fr 1-Fr 7) revealed that Fraction 1,2,3 could be separated easily and that the chemical components are similar. Keywords: Proximate analysis; Hepatotoxicity; Carbon tetrachloride; Mineral content; Sarcocephalus latifolius

N March, 1939, the CANADIAN HISTORICAL R•.VI•.W published a short statement by Dr. C. T. Currelly, Curator of the Royal Ontario Museum, with regard to the Beardmore Relics, under the title "Viking Relics Found Near Beardmore, Ontario." Later in the year, Mr. J. W. Curran, the editor of the Sault Daily Star published a large amount of evidence and his conclusions in the book Here Was Vinland. In May, 1940, a paper on the Beardmore relics was read before section II of the Royal Society of Canada by Mr. O. C. Elliott of Kingston, Ontario. In preparing it Mr. Elliott had the collaboration of Dr. T. L. Tanton of the Dominion Geological Survey. Both before and since Dr. Currelly's announcement, a great deal of time and effort has been expended by a number of people in collecting information with regard to the history of the relics. The following pages provide a survey of evidence thus far available, and statements of views with regard to it. The survey of evidence has been written by Mr. Elliott, who first attracted the attention of the Museum to the relics by drawings which he sent to Dr. Currelly and who has given the subject a great deal of investigation since that time. Since the story is a tangled one, the article has not attempted a lengthy discussion, but has been written rather for the purpose of presenting the essential points of evidence and the chief questions raised by them. The file of the Museum was made available to Mr. Elliott while he was preparing his article. The article is followed by two brief statements commenting on the evidence, the first by Dr. Currelly, the second by Mr. Elliott. [EDITOR'S NOTE]


Anxiety normally occurs in life, but anxiety can become abnormal if the response to the stimulus is excessive. In student, anxiety affects the educational process. OSCE is a part of comprehensive exam that examine medical skills of the students who will enter their clinical stage. Although this exam is similiar like skills lab exam but the matters of exam is more complex and the setting of exam is different too, so these situations cause anxiety in students toward OSCE. OSCE is a clinical examination to test students' skill. Students have to demonstrate skill possessed by the different conditions and examined by a particular examiners. The condition potentially the students suffering of anxiety in which symptoniced by phsichologies as students' scared, felt nervous insecure. Impacts of anxiety caused reduction of students' skill in pursuing their tasks thereby get the bad result.

where he and his students study the theory and practice of network and system administration. He served as Program Chair of LISA '02 and was a recipient of the 2003 SAGE Outstanding Achievement Award for contributions to the theory of system administration. He currently serves as Secretary of the USENIX Board of Directors. ways to transform the question " Why does this fail? " into the related question " Is this fast enough? " Fellow system administrators, do you find yourself troubleshooting systems more and enjoying it less? Do you spend most of your time correcting the " same old problems " ? Are legacy systems millstones around your neck? Then, from what I can tell, you are like most system administrators. For those of you in this situation, I have a controversial message: The troubleshooting you are doing now is already obsolete. In the following, I will outline techniques for minimizing common kinds of trouble by use of virtu-alization. Most of these techniques are common knowledge, and I apologize in advance for stating the obvious. But, in my experience, many system administrators of good faith and stronger character than my own still endure these various tribulations. This article is written for them because I think they remain in the majority. No strategy I am going to suggest actually eliminates trouble. Instead, trouble is transformed into a hopefully more manageable form. Virtualization allows one to replace configuration troubleshoot-ing with performance troubleshooting. One key to understanding this transformation is to consider it as part of the " thermodynamics of system administration. " System administrators, like mechanical engineers and physicists, have to cope with conservation laws, and one thing that is conserved is trouble. We cannot eliminate trouble, but we can make choices that transform it into a perhaps more manageable (and hopefully " user-friendly ") form. Trouble is a form of entropy, and thus it is subject to the laws of thermodynamics. Ginsberg once described the three laws of thermodynamics as " One can't win, one can't break even, and one can't get out of the game. " In system administration terms, we might restate these laws as follows: There is no way to prevent trouble. There is no zero-cost way of transforming ■ ■ trouble into other forms. Trouble approaches zero only as system use ■ ■ approaches zero. The theme of this article is the second law. In system …
