A stabilizing linear static controller is discovered for a linear time-varying uncertain system of Petersen. We use the concept of a sandwich cone decomposition to show that Petersen's system is stabilizable by linear static controllers. We establish the surprising result that Petersen's system is stabilizable against time-varying uncertainties on any given compact subset of the uncertainty controllability space. Our work suggests the use of "scalar-quadratic" Lyapunov functions, a special subclass of polyhedral Lyapunov functions, in establishing stability for other linear time-varying uncertain systems, and it reopens the study of the conjecture: stabilizability via nonlinear control always implies stabilizability via linear control. >


Objectives:This study was conducted to evaluate the efficacy of four kinds of desensitizing agents for the treatment of dentin hypersensitivity.Methods:Seventy hypersensitive teeth in 10 patients were divided into five groups:group Ⅰ,10% strontium chloride; group Ⅱ, 5% potassium nitrate;group Ⅲ, 6% sodium fluoride and 6% calcium fluoride; group Ⅳ, 40% formalin; group Ⅴ, control.The stimulus used to test thermal sensitivity was cold water.Results:10% strontium chloride,5% potassium nitrate, 6% sodium fluoride and 6% calcium fluoride solution,and 40% formalin significantly reduced dentin hypersensitivity ( P 0.05), whereas 6% sodium fluoride and 6% calcium fluoride solution achieved the best effect ( P 0.05).Conclusions:10% strontium chloride, 5% potassium nitrate, 6% sodium fluoride and 6% calcium fluoride solution,and 40% formalin are efficient in the treatment of dentin hypersensitivity.


Corrosion of steel reinforcement in concrete structures is a critical problem that designers, contractors and owners have to face everywhere. The corrosion resistance of Fiber Reinforced Polymers (FRP) bars makes them attractive for the replacement of steel reinforcement if it can be ensured that their mechanical and physical characteristics remain stable over time under service conditions. § Corresponding author Micelli F., A. Nanni, and A. La Tegola, "Effects of Conditioning Environment on GFRP Bars," 22 SAMPE Europe International Conference, CNIT Paris, March 27-29, 2001. 2 The durability of Glass FRP (GFRP) materials used in construction is related, among the other things, to the conditions within concrete. Several studies have suggested that the high alkalinity of the cementitious environment and thermal variations act as a catalyst for stress corrosion mechanisms driven by the exchange of alkali metal ions (Na and K). At the same time, environmental agents including high relative humidity, freeze-thaw cycles, and high temperatures may produce a reduction of mechanical properties. This paper compares the effects of two conditioning environments on the physic-mechanical properties of GFRP rods. The aim of the study is to show that the proposed accelerated ageing regimens allow to clearly differentiate between different products. Two types of GFRP rods investigated in this work were subjected to alkaline solutions at 60 °C for two different exposure times, while other specimens were exposed to environmental ageing in a controlled chamber. Tensile and short beam tests (SBT), according to provisions from ACI 440 and ASTM D4475, respectively, were used for physic-mechanical characterization, while gravimetric measurements were used to study the absorption behavior. The correlation between the tensile test results, apparent horizontal shear strength, and gravimetric measurements allowed to determine the changes in mechanical properties due to fibers and resin degradations, as a result of the accelerated aging.


In this paper, we investigate the properties of upper approximation operators and Alexander fuzzy topologies induced by maps in complete residuated lattices. We give their examples.

THIS PAPER DEVELOPS SOME FUNDAMEDNTAL PROCEDURES FOR OBTAINING TRAFFIC SIGNAL OFFSETS WHICH MINIMIZE THE TOTAL LOSS TO TRAFFIC IN A NETWORK. THESE PROCEDURES HAVE SOME COMMON ASSUMPTIONS: (1) ALL TRAFFIC SIGNALS IN A NETWORK HAVE A COMMON PERIOD, (2) THE RED-GREEN SPLIT IS GIVEN AT EACH SIGNAL, AND (3) THE LOSS TO TRAFFIC GENERATED IN A LINK WHICH HAS INTERSECTIONS AT BOTH ENDS OF IT DEPENDS ONLY ON THE TRAFFIC FLOW ON IT AND THE OFFSETS AT THOSE INTERSECTIONS, AND, ACCORDINGLY, IS INDEPENDENT OF OFFSETS AT ANY OTHER INTERSECTIONS. THE MATHEMATICAL PROCEDURES USED IN THE PAPER ARE DYNAMIC PROGRAMMING AND THE DISCRETE MAXIMUM PRINCIPLE. IN BOTH CASES, A NETWORK IS DIVIDED INTO SOME SECTIONS THAT CORRESPOND TO STAGES IN A MULTISTAGE DECISION PROCESS AND THE OBJECTIVE FUNCTION OR THE TOTAL LOSS IN THE NETWORK IS MINIMIZED IN PASSING THROUGH THOSE SECTIONS. AS A NUMERICAL EXAMPLE, THE OPTIMAL OFFSET PATTERN IS DETERMINED FOR A SMALL NETWORK THROUGH THESE TWO PROCEDURES. IN ADDITION, THE MINIMUM LOSS OBTAINED BY THIS OPTIMIZATION IS COMPARED WITH THE TOTAL LOSS GENERATED IN THE NETWROK WHEN ONLY TRAFFIC SIGNALS ON MAIN STREETS ARE OPTIMALLY CONTROLLED, THE NETWORK IS SYNCHRONIZED UNDER A ONEWAY SYSTEM, OR THE SIGNAL AT EACH INTERSECTION IS CONTROLLED INDIVIDUALLY.

Main patterns of gas chromatographic and mass spectrometric analyses of these substances are described.


The study evaluates the use of electrets as a new contamination-detecting device designed to assess the chemical composition of rocket effluents. Evaluation of electret effectiveness revealed that electrets have multipollutant-measuring capability, simplicity of deployment and rapidity of assessment. Advantages of electrets are small size, light weight and cost-effectiveness. It is shown that electrets compare favorably with other HCl measuring devices. In particular, the summary of the measured data from electrets and HCl detectors is within the limits of computed HCl concentrations from the NASA/MSFC multilayer diffusion model.


With the increase in wireless communication technology, encryption of information sent has become a major concern. This involves both the software level and hardware level encryption. GSM was the first cellular system that paid attention to secure mobile communication. Before the advent of GSM the cellular system had no particular security. The GSM voice calls are encrypted using a family of algorithms collectively A5 all of which are currently badly broken. This paper covers the software simulation of A5/1 algorithm and the complexity of various simulators used. As per the analysis serious security weakness are found in A5/1 algorithm. These simulation work as a base for improving the security of A5/1 algorithm. The justification of any enhancement to algorithm lies in effective simulation of enhancement. Thus, this paper gives comparative analysis of various simulation techniques. NIST - Security Test suite is used for cryptographic analysis of the algorithm.

From certification to No Child Left Behind, and school district bus requests to Perkins Law, academic standards, program standards, and content standards are permeating agricultural education nationwide. At least in Idaho, all three types of standards appear to be here to stay. The question becomes: do these standards make us better teachers and as a result, do we provide a better education to our students? The Idaho state Professional-Technical Education Program Standards and Agriculture Content Standards have been in place at the state level since the mid-1980s. The implementation of state-wide program standards for quality assurance and qualification for state added-cost funding has become integral to all professionaltechnical education programs in the state of Idaho. The advent of the National Program Quality Standards and the National Content Standards for Agricultural Education are (thankfully) directly related to the state standards that are currently in place. Idaho's Quality Initiative was adopted and implemented in the mid- 1 990s as an extension and supplement to the state's program quality standards. The main motivation for the local secondary PTE programs in Idaho to actively implement and abide by the state's Quality Initiative and meet the minimum program quality standards is MONEY. Idaho's legislature annually funds the local secondary PTE programs through added cost funding provided through the Idaho Division of ProfessionalTechnical Education. The amount of the funding is contingent on the program area in question: Family and Consumer Science programs generate $4,400 per teacher FTE, up to Collision Repair automotive programs that generate over $ 1 8,000 per teacher FTE, with Agricultural Science and Technology programs generating $10,260 per teacher FTE each year. These funds are provided in addition to the standard school funding generated for the local school district and are not related to Perkins funding. The Idaho Quality Initiative states that the Idaho Division of Professional-Technical Education wants to ensure and support curriculum that is rigorous, relevant, measurable, and allowing for sufficient complexity in PTE. The components of the quality initiative require that the local rigorous technical programs meet industry standards, use technical achievement measures, and instruct on all aspects of the industry. Additionally, quality programs integrate Idaho academic achievement standards and provide opportunities for articulation of high school and college curriculum (Quality Initiative, 2008). PTE programs in Idaho are generally evaluated by the program manager for that area every five years. Program evaluation is based on the Essential Program Components, or program quality standards. Programs MUST be Approved by the program manager in order to receive the added cost funding allocation. The program standards are divided into two categories: essential (power) standards and general standards. The list below includes only the power standards. For a complete list of the Idaho Program Quality Standards, please visit the Program Visit information page of the Idaho ProfessionalTechnical Education website: http://www.pte.idaho.gov/ Teachers/Program VisitInfo.html. ADMINISTRATION * General standards only included for program administration. STAFF * Instructor holds current and appropriate professionaltechnical certification and endorsement(s). PROGRAM OF STUDY * Classes offered follow a sequence of courses for a specific program. * An advisory committee that represents various aspects of the industry and community meets regularly and provides input for program improvement. * Leadership development is integral to the program and is generally provided through Professional-Technical Student Organizations. CAREER GUIDANCE and TECH PREP * General standards only included for program career guidance and tech prep. …


As the leader of the fifth generation of directors in China, Zhang Yimou leads Chinese films to the world in the new era. He is an outstanding representative of Asian films and a world-renowned film master. This paper takes visual art as the tool and mainly studies the symbolic expression of Zhang Yimous film. The research allow readers to access the Chinese classic film symbol and Zhang Yimous personal characteristic film symbol by analogy Zhangs several films. Through the online research on Douban and Zhihu, the author made a brief appreciation of the visual language features of Zhang Yimous two films To Live and Red Sorghum with the highest score and voice.The author makes some discussions on the composition characteristics, techniques and creation style of Zhang Yimou's films. On the one hand, the author believes that Zhang Yimou and his films are deeply influenced by the structure of traditional Chinese aesthetics. Zhangs film not only display grand Chinese aesthetics in the structure of the picture, but also intersperse many unique Chinese meanings in the film. From the creative technique, Zhang is good at using scenes to foil atmosphere and allude to the characters fate. On the other hand, Zhang Yimous typical male chauvinist creation style is reflected in many aspects of his film, such as female stereotypes, improper male gaze.

In linear stability analysis of field quantities described by partial differential equations, the well-established classical theory is all but impossible to apply to concrete problems in its entirety even for uniform backgrounds when the spatial dimension is more than 1. In this study, using the Lefschetz thimble method, we develop a new formalism to give an explicit expression to the asymptotic behavior of linear perturbations. It is not only more mathematically rigorous than the previous theory but also useful practically in its applications to realistic problems, and, as such, has an impact on broad subjects in physics.

for each/ in C[0, 1], the class of continuous functions from [0, l] to the complex numbers. Indeed, we find that this proposal is precisely the assertion that the sequence p, pn = l/2n (re = 0, 1, • • • ),is a regular Hausdorff mom,ent sequence with limit 0. The latter assertion is well known: for relevant ideas, one may consult [4, Chapters 14 and 16] and, especially, [4, p. 309] regarding the Euler-Knopp mean (E, 1/2) associated with the aforementioned sequence p. The connecting link is the following result.


We present a convolutional network capable of generating images of a previously unseen object from arbitrary viewpoints given a single image of this object. The input to the network is a single image and the desired new viewpoint; the output is a view of the object from this desired viewpoint. The network is trained on renderings of synthetic 3D models. It learns an implicit 3D representation of the object class, which allows it to transfer shape knowledge from training instances to a new object instance. Beside the color image, the network can also generate the depth map of an object from arbitrary viewpoints. This allows us to predict 3D point clouds from a single image, which can be fused into a surface mesh. We experimented with cars and chairs. Even though the network is trained on artificial data, it generalizes well to objects in natural images without any modifications.


Early dynamical evolution of close-in planetary systems is shaped by an intricate combination of planetary gravitational interactions, orbital migration, and dissipative effects. While the process of convergent orbital migration is expected to routinely yield resonant planetary systems, previous analyses have shown that the semi-major axes of initially resonant pairs of planets will gradually diverge under the influence of long-term energy damping, producing an overabundance of planetary period ratios in slight excess of exact commensurability. While this feature is clearly evident in the orbital distribution of close-in extrasolar planets, the existing theoretical picture is limited to the specific case of the planetary three-body problem. In this study, we generalise the framework of dissipative divergence of resonant orbits to multi-resonant chains, and apply our results to the current observational census of well-characterised three-planet systems. Focusing on the 2:1 and 3:2 commensurabilities, we identify three three-planet systems, whose current orbital architecture is consistent with an evolutionary history wherein convergent migration first locks the planets into a multi-resonant configuration and subsequent dissipation repels the orbits away from exact commensurability. Nevertheless, we find that the architecture of the overall sample of multi-planetary systems is incompatible with this simple scenario, suggesting that additional physical mechanisms must play a dominant role during the early stages of planetary systems' dynamical evolution.


Maintaining solar plant maximum energy production requires a regular inspection of solar panels. Images stitching technique of captured videos is usually used to form panoramic image view of the solar plant. Analyze of those images help supervisors to detect cracks, dust accumulation,. … Often captured videos are done using moveable devices, such as vehicle robots and drones. Usually, motion and shaking of devices provoke some blur captured frames which affect drastically the stitching process. In this paper, we study, experiment, and compare a set of techniques allowing to detect and discard blurred frames. As result, the algorithm based on Fourier Transform allows an efficient (i.e. accuracy of about 98%) and rapid treatment which can be easily integrated into online stitching process.

Blood samples from 108 obese individuals (73 males and 35 females) and 106 healthy ones (79 males and 27 females) were collected from a cohort of Saudis inhabiting Riyadh province. ATP6 mitochondrial gene was amplified and sequenced to identify obesity-related SNPs and the mitochondrial DNA haplogroups for forensic purposes. A novel site (A8660G) was found while C8655T and T9103C were obesityrelated sites. The haplogroups H2a and H1a were common as they were found in 70.4% and 66% of obese and non-obese individuals, respectively. L2 was recorded in the obese samples only and H21 was recorded in the obese males only. The J2a haplohroup was more common in obese individuals. Constructing mtDNA database for people inhabiting different regions of Saudi Arabia for forensic purpose and to affirm the utility of H21 and L2 in identifiying obesity is necessary.


There has been little work conducted over the last 40 years on estimating vitamin requirements of poultry, and so consequently NRC (1994) values are still often quoted as standards. A review of this information indicates many values are estimates, or extrapolated from comparable species, or as with broiler breeders, simply not given. The current concern related to formulating vitamin levels in poultry diets is the assumption that change in genetic potential of layers and meat birds necessitates re-evaluation, and that parameters for assessing needs are now more complex than simple production metrics as used previously. Unfortunately information on maintenance needs for vitamins is lacking, and while there is now information available on vitamin content of eggs, comprehensive details of the vitamin level in poultry meat products is surprising lacking. With unprecedented egg output of modern layer strains, and ever improving feed efficiency in meat birds, vitamin intake per unit of output is continually declining. For layers the estimate is around a 1% yearly decline in vitamin intake per egg produced, while for meat birds there has been a 0.6-0.8% yearly decline per kg body gain. This reduced intake of vitamins is the basis for improved performance in layers and meat birds fed a higher than normal level of vitamins. However, an even more important basis for reevaluating vitamin needs is change in measurement criteria. Many vitamins and especially the fat soluble vitamins accumulate in eggs and meat in proportion to diet inclusion. Development of vitamin enriched designer poultry products therefore dictates elevated feeding levels of vitamins. Co-incidentally, increased levels of vitamin E in poultry products has led to the realization that increased antioxidant capacity of these tissues enhances shelf life and appearance. Of greatest impact in reevaluating diet vitamin specifications has been the effect of these nutrients on bird health and in particular immune response. For example dietary levels of vitamin E far in excess of NRC (1994) requirements have been shown to positively impact immune response in all ages of bird and also the performance of heat-stressed birds. Expectations of ever increasing performance dictate the need for continual reevaluation in determining vitamin levels within diet formulations as detailed in recent publications on optimum vitamin nutrition of poultry to improve health, welfare, performance and the quality of poultry products.


The aims of this study were (1) to determine the trend of retail rice price in Indonesia and the price of grain at the farmer level in Indonesia and (2) to identify the vertical integration of the rice market in Indonesia. The monthly data of retail rice price and the price of grain at the farmer level (price of harvested dried grain at the farmer level) in Indonesia during January 2008 - January 2016 were used in this study. The least squares method was applied to determine the trend of prices, while Co-integration Model of Engle-Granger and ECM was used to estimate the vertical integration of Indonesian rice market. The results indicated that both types of prices had an upward trend. In the analysis of the vertical integration of rice market in Indonesia, there was a long-term balance relationship and short-term equilibrium relationship.


The subject of this article is the tale aesthetics of one of the richest areas in Dagestan folklore – faerie epos, which found its artistic reflection in specific cites of plot composition of the themed sequence of tales "On Stepmother and Stepdaughter". The aforementioned tales are characterized by the narrative-thematic variety and richness of poetic means and techniques. The object of this research is the narrative-compositional, stylistic and poetic peculiarities of fairytales to the world famous storyline "On Stepmother and Stepdaughter". The goal of this work consists in illustration of the narrative-thematic variety and determination of the character of science fiction substantiated by specificities of the genre using the method of comparative-historical and analytical analysis, based on tales to the story "On Stepmother and Stepdaughter" popular in the folklore of multiple ethnic groups of Dagestan – Avars, Dargins, Kumyks, Laks, Rutuls, Tabasarans, Nogais, etc. The scientific novelty consists in the first comprehensive study of the variety of narrative-thematic content of the sequence of fairytales, as well as determination of their ideological-aesthetic foundation and distinctness of compositional structure. Some tales do not deviated from the theme of "stepmother – stepdaughter" conflict; some include various side episodes of science fiction nature full of magic and miracles; and some contaminate with the tales to a different storyline, theme or motif.


The profitability of many laying flocks is often predetermined in the pullet house weeks before an egg is laid. Greater realization of this aspect coupled with the development and maintenance of a strong, practical pullet development program can increase net income levels significantly for many commercial egg producers. Careful investigations usually reveal that an operation with repeatedly high performing flocks consistently houses good quality replacements. Such flocks are usually from reputable, well managed sources with rearing programs synchronized to laying programs. In contrast, some egg producers have little or no control over, or knowledge of, the rearing program to which replacement pullets are subjected. Invariably these producers house occasional flocks which never meet expectations even under an excellent laying house management program. Such flocks may peak too early or at a lower rate of lay than expected. Production may drop too rapidly. Attaining body weight and egg size may be a problem. Shell and/or interior quality may be poor. Feed efficiency may be poor and production may be affected by positive or suspected disease outbreaks. Such typical shortcomings in properly managed laying flocks are almost invariably caused by one or more deficiencies in the rearing program. Deficiencies may include inadequate ration formulation or severe feed restriction, crowding, improper lighting, poor flock health management and vaccination practices, improper debeaking or one or more other preventable stresses.

Objective: Data on human papillomavirus (HPV) infections and their related lesions appearing simultaneously at different anatomical sites are scarce. Our aim was to provide information about HPV infection and lesions of the cervix, anal canal, and mouth of women at different risk conditions to be infected by HIV. Methods: Cross-sectional study. Detection and genotyping of HPV infections were done by multiplex PCR, and the cytology by Papanicolaou test. HPV Prevalence and associated risk factors were estimated. Results: The study included 108 women (44 at risk and 64 with no risk of HIV-infection). The highest prevalence of HPV infection was found in the anal canal (26% at HIV-risk versus 28% with no risk group, p=0.79), followed by the cervix (14% versus 28%, p=0.07) and the oral cavity (7% versus 9%, p=0.64). HPV16 was the most prevalent type in cervix (5.6%) and anus (8.6%) for both groups but HPV52 (4.5%) was the most frequent type in the mouth of the at-risk group. Interestingly, women from the at HIV-risk group presented higher prevalence of anal infection involving a wider range of different high-risk oncogenic HPV-types. Concomitant HPV infections with HPV16, 18 and other oncogenic types (HPV56, 59) were found in 3.1% of women (all three areas) and 7.1% (cervix and anal canal). As regards HPV-related lesions, no statistical differences were observed between groups, although women at HIV-risk had higher proportion of anal abnormalities (18.4% versus 8.2%, p=0.19). Finally, cervical HPV-infection was significantly associated with presence of cervical or anal condylomata and alcohol consumption and anal HPV-infection with smoking and RAI. Conclusion: Both women at risk of HIV-infection or with anogenital warts presented a wider range of HPV-oncogenic types in the anal canal, resulting good candidates for HPV anal screening and monitoring programs.

Many properties of simple finite dimensional gl(m|n)-modules may be better understood by assigning weight diagrams to the highest weights with respect to a given base of simple roots. In this paper we consider bases that are compatible with the standard Borel subalgebra in $gl(m|n)_0 = gl(m) \times gl(n)$; namely, the bases that differ from the distinguished base $\Sigma^{dist}$ of simple roots by a sequence of odd reflections. We examine the weight diagrams that arise from the highest weights of a simple module $L(\lambda)$ with respect to such bases. Further, we provide combinatorial tools to describe all the weight diagrams of highest weights of $L(\lambda)$ provided only with the the weight diagram of $L(\lambda)$ with respect to distinguished highest weight $\lambda$. Finally, we study the maximal cardinality of incomparable sets of positive odd roots with respect to $\Sigma^{dist}$ which are orthogonal to some highest weight of $L(\lambda)$ with respect to a base as above. We provide explicit formulas for this value, connecting it to the combinatorics of the weight diagrams. Based on this study, we respond to the work of M. Gorelik and Th. Heidersdorf, providing a counterexample to their Tail Conjecture.

We study an auction game in which two units of a good are sold via two second price auctions sequentially. Bidders value the units identically and have one of two budget levels, high or low. Bidders do not know each others budgets. We show that this game has a unique symmetric equilibrium in which the probabilistic presence of high budget bidders can make bidders bid more aggressively in the first auction, thus lowering prices in the second. As a result if the possibility of competition from high budget bidders is large, then the equilibrium strategies generate declining prices.


Topside reverberations off mantle discontinuities are commonly observed at long periods, but their interpretation is complicated because they include both near‐source and near‐receiver reflections. We have developed a method to isolate the stationside reflectors in large data sets with many sources and receivers. Analysis of USArray transverse‐component data from 3,200 earthquakes, using direct S as a reference phase, shows clear reflections off the 410‐ and 660‐km discontinuities, which can be used to map the depth and brightness of these features. Because our results are sensitive to the impedance contrast (velocity and density), they provide a useful complement to receiver‐function studies, which are primarily sensitive to the S velocity jump alone. In addition, reflectors in our images are more spread out in time than in receiver functions, providing good depth resolution. Our images show strong discontinuities near 410 and 660 km across the entire USArray footprint, with intriguing reflectors at shallower depths in many regions. Overall, the discontinuities in the east appear simpler and more monotonous with a uniform transition zone thickness of 250 km compared to the western United States. In the west, we observe more complex discontinuity topography and small‐scale changes below the Great Basin and the Rocky Mountains, and a decrease in transition‐zone thickness along the western coast. We also observe a dipping reflector in the west that aligns with the top of the high‐velocity Farallon slab anomaly seen in some tomography models, but which also may be an artifact caused by near‐surface scattering of incoming S waves.


Basic problems related to manufacturing of polymer impregnated cementitious materials are discussed. Experimental studies on drying, impregnation and polymerization are presented. In addition ot these conditions of the treatment, mix proportion of the base material should be carefully selected so as to optimize a property aimed at. Mechanical strength of PIC is influenced by self stress generated in the material possibly due to shrinkage caused by polymerization and the difference in thermal coefficients of expansion of polymer and concrete. Annealing and addition of a plasticizer are useful methods in reducing this self stress. Improvement of strength is analyzed by Griffith theory, and uniformity of PIC is evaluated by Weibull's theory. Both of these analyses indicate that the impregnation is a reasonable method to improve mechanical properties of cementitious material, though shrinkage caused by this treatment should be deliberately taken into account when the material is further reinforced with steel or other fibers. Products manufactured by the process studied in this report have shown good performances in actual service to date. /ACI/


Recently, we suggested a model of magnetic monopoles (hep-ph/9708394). Here we will propose a tabletop experiment to test this model. The verification of the predicted effect would have far-reaching consequences.


Cereal beta-amylases are perhaps best known in terms of the vital role they play in releasing easily fermentable sugars from cereal grain starch to fuel the production of alcohol by yeast in brewing. The extent to which they have been investigated is indeed largely due to their significance in this economically important industry. However, cereal beta-amylases are also, or could be, employed in many other aspects of the food industry and the analysis of starch, and they constitute valuable markers in cereal assessment and breeding studies. Quite apart from their practical significance, they are rewarding objects of biochemical and physiological research. They are interesting models for the study of enzyme polymorphism, post-translational modification and the differential expression of isoenzymes. In spite of their often high activities in situ and all that is known about their generation, they are an enigma in that their physiological function, or even necessity, remains unclear. It has been recently recognised that there are two different categories of cereal beta-amylases which exhibit different tissue and taxonomic specificities and physiological developmental patterns. The classical' beta-amylases present at high activities in cereal seeds appear to be limited to the endosperm of the species of the Triticeae tribe of the Festucoideae subfamily of the Gramineae (wheat, barlcy and rye), whereas all cereals exhibit a different, tissue-ubiquitous' form of the enzyme which is present at much lower activity levels. The physiological phenomenology and the usage of cereal beta-amylases are discussed in relation to these two categories of enzyme.


The effects of oxygen transfer on the β-lactamase production by Bacillus licheniformis were investigated in a glucose-based defined medium. The experiments were conducted in 3.0 dm3 batch bioreactor systems at three different air inlet (QO/VR = 0.2, 0.5 and 1.0 vvm) and agitation rates (N = 250, 500 and 750 min−1). During the fermentation, the concentrations of the cell, glucose, by-products, ie organic and amino acids, oxygen transfer coefficients (KLa), yield coefficients, specific rates and oxygen uptake rates (OUR) were determined, in addition to β-lactamase activities. The highest β-lactamase activity was obtained at QO/VR = 0.5 vvm and N = 500 min−1 and at QO/VR = 0.2 vvm and N = 500 min−1 conditions, as caA = 90 U cm−3. The highest cell concentration was obtained as CX = 0.67 kg m−3 at QO/VR = 0.5 vvm and N = 750 min−1 and at QO/VR = 0.2 vvm and N = 750 min−1 conditions. The values of KLa increased with increasing agitation and aeration rates and varied between 0.007 and 0.044 s−1, and the OUR varied between 0.4 and 1.6 mol m−3 s−1. With increasing QO/VR and/or N, the Damkohler number (ie the oxygen transfer limitation) decreased owing to the increase in mass transfer coefficients (KLa). The highest instantaneous yield of cell on substrate (YX/S) and yield of cell on oxygen (YX/O) values were respectively obtained at 0.5 vvm and 500 min−1 conditions at t = 2 h as YX/S = 0.72 kg kg−1 and YX/O = 1.49 kg kg−1. The highest instantaneous yield of substrate on oxygen (YS/O) was obtained at 0.5 vvm and 750 min−1 conditions at t = 20 h as YS/O = 8.07 kg kg−1. Copyright © 2005 Society of Chemical Industry


Queuine, a modified base found in transfer RNA, appears to be a new dietary factor because (i) previous studies have shown that mice require it for the expression of queuine-containing transfer RNA's but apparently do not synthesize it, and (ii) significant amounts of free queuine are present in common plant and animal food products.

Deep space electric propulsion exploration mission has its particularity. The light intensity varies widely during the mission, resulting in a large change in the output power range of the solar array. The spacecraft uses a high-power electric propulsion system, and the power system has strict weight requirements, so the existing power supply system design cannot meet the requirements. Aiming at the design constraints of the large variation of solar array light intensity, the large difference in power requirements between the electric propulsion and the platform, and the lightweight design of the spacecraft, a dual-bus power supply system is proposed. The solar array directly converges to form a high-voltage bus, which supplies power for the electric propulsion system. The low-voltage bus adopts a semi-regulated bus. Product test results show that the power system design can meet the working requirements of electric propulsion and platform loads. The power system design can provide reference for the other deep space exploration power system.


Optical second harmonic generation in radio‐frequency sputter‐deposited AlN thin films has been studied for harmonic wavelengths from ultraviolet to near infrared. The effective second‐order nonlinearity χ(2)(ω) was determined to have a nonresonant background value of ∼5×10−9 esu for second harmonic wavelengths longer than 400 nm, and it increases dramatically as the second harmonic frequency approaches the bandgap of 6.2 eV. This is likely due to resonance of the second harmonic frequency with the critical point transition associated with the direct bandgap of AlN.


This work presents a self-biased 2-stacked power amplifier cell that shows, in simulations, an output power in excess of 33 dBm and gain and power added efficiency (PAE) above 6 dB and 27 %, respectively, over a 33.5 GHz to 39.5 GHz bandwidth. The cell has been developed on a commercial 100 nm GaN-on-Si process, applying space derating rules at center frequency, where the output power is almost 33.8 dBm, the associated gain is higher than 7 dB and PAE is above 35 %.


The regeneration of spent dye-loaded CMC(caboxymethylcellulose sodium)immobilized live Aspergillus fumigatus beads by desorption of reactive blue KN -R and reactive red K -2BP was investigated,and the technical process of biosorption-reuse of dyes by CMC immobilized live A.fumigatus beads was proposed.Results showed that the desorption efficiency of reactive blue KN-R and reactive red K-2BP using 75% ethanol at pH 12.0 was 60.8% and 50.4% in 30min respectively.The desorption kinetics data fit well with the first order decay model.The CMC immobilized live A.fumigatus beads could be reused up to three times for decolorization application.


The grain size distribution of six Luna 24 samples has been determined. These samples are characterized by a bimodal distribution which is indicative of soils formed primarily by mixing rather than by reworking. Although agglutinate content decreases with depth, it is not likely that the Luna 24 soils have undergone appreciable in situ reworking. Particle types and abundances in each of four size fractions have been determined petrographically. Mineral fragments are very abundant in all analyzed size fractions. Pyroxene and plagioclase increase slightly in abundance at finer grain sizes, but olivine decreases significantly. Compared with typical mare soils, the Luna 24 trends are anomalous. They are compatible with the hypothesis than many, if not most, of the mineral grains in the 20-250-micron fractions come from coarse-grain rocks having average mineral grain sizes greater than 250 microns. The mineralogy and chemistry of the coarse-grained rocks has not been well characterized, but there is evidence that at least some of them are higher in MgO than the analyzed finer-grained basalts.


Despite their reputation, not all plasmas are difficult to confine. In fact, one kind of plasma can be kept for long times in a simple apparatus by means of static electric and magnetic fields. It is the kind of plasma that consists exclusively of particles with a single sign of charge. Examples include pure electron plasmas, positive ion plasmas of one or more species, positron plasmas and even electron‐antiproton plasmas—all of which have been realized in recent experiments.


A bipolar dynamic memory cell for use in a high-speed random- access memory consists of a cross-coupled pair of transistors and two diodes. Information is dynamically stored using a bistable charge distribution and must be refreshed at a frequency of 1 kHz by a SELECT operation. Standby power per memory cell is in the nanowatt range. The cell requires only 3 interconnect lines and can be fabricated with standard bipolar technology on 12-mil/SUP 2/ silicon area. Cycle time is limited by the speed of decoding, driving, and sensing circuits and is estimated to be 50 ns for a 512-bit RAM chip with complete on-chip decoding.


Five parallel transects(1m×40m1m×70m)placed 50m apart,were sampled at the altitude of 4000m from south-slope to north-slope in Songpan county which lies in the eastern edge of the Qinghai-Tibet Plateau.During 20042005,all 251 quadrats(1m×1m)were investigated in terms of plant community composition,physicochemical characteristics of soil,and depth of winter snow-cover.The functional module TWINSPAN of software PC-ORD was used to classify the plant communities,based on relative frequency as the community index,and an environmental index comprising depths of snow-cover,soil and organic matter,soil moisture(0.25mm and 2mm),total P,total K,NH+4-N,hydrolytic acid,pH,slope etc..CCA was then used to classify plant communities.The results show four community types from south-slope to north-slope:Potentilla-Ajania alpine shrub meadow,Ptilagrostis-Carex alpine meadow,Salix-Carex-Ptilagrostis alpine shrub meadow,and Rhododendron alpine shrub.From south-slope to north-slope,herb cover decreased from 75% to 39%,and shrub cover increased from 25% to 54%.And around the mountain ridge(about 50m)the type of vegetation in south-slope and north-slope shows significant differences.In the winter of 2005,the average snow depth on the south-slope was 21cm,compared to 26cm on the mountain ridge and 34cm on the north-slope.Snow depth was positively correlated with shrub cover(r =+0.40,p0.01,n=248),but negatively correlated with herb cover(r=-0.45,p0.01,n=248).ANOVA indicated that soil depth,soil moisture,pH,soil organic matter and total P differed between north and south slopes,tending to increase from south-slope to north-slope,and significantly correlated with the average snow depth(r=0.267,0.286,0.199 and-0.183,respectively,p0.05,n=119);soil total K and NH+4-N showed no significant differences with aspect,and no significant correlation with average snow depth(r=-0.068 and 0.104,respectively;p0.05,n=119).This suggests a complex interaction between aspect,snow depth,and a variety of soil characteristics.The CCA order of community,as well as the correlation analysis of compositor axis and environment index also showed that slope,snow-cover thickness,soil organic matter and soil moisture were the primary factors that induced the different plant community types in south-slope and north-slope,while the impact of soil NH+4-N and total K were not significant.


following conditions: 1) three sets of four non-ballistic repetitions (30N-B), 2) three sets of four non-ballistic repetitions with a 3-second pause between the eccentric and concentric phases (30PN-B), 3) three sets of four ballistic repetitions (30B), 4) three sets of four ballistic repetitions with a 3-second pause between the eccentric and concentric phases (30PB). Force plates and a 3-D motion analysis system were used to determine the total mechanical work performed during each session while a portable gas analysis system was used to collect expired gases. RESULTS: Total mechanical work performed during each set was significantly greater during 30B compared to 30N-B (mean difference [MD]: 7,792 J, p<0.001, effect size [ES]: 1.88) and 30PN-B (MD: 7,749 J, p<0.001, ES: 1.89), while that during 30PB was significantly greater than that during both 30N-B (MD: 7,488 J, p<0.001, ES: 1.89) and 30PN-B (MD: 7,445 J, p<0.001, ES: 1.90). Energy expenditure during each set was significantly greater during the 30B condition compared to the 30N-B (MD: 13,983 J, p<0.001, ES: 1.08) and the 30PN-B (MD: 11,326 J, p=0.001, ES: 0.92). Energy expenditure during 30PB was also significantly greater than that during 30N-B (MD: 12,615 J, p=0.001, ES: 1.04) and 30PN-B (MD: 9,958 J, p=0.006, ES: 0.86). Furthermore, energy expenditure during set 1 was significantly greater than that during set 2 (MD: 6,840 J, p<0.001, ES: 0.64) and set 3 (MD: 8,070 J, p<0.001, ES: 0.75). CONCLUSION: Ballistic resistance training exercises may represent a more effective metabolic stimulus compared to traditional resistance training exercises and a pause inserted between the eccentric and concentric phases has little effect.


Experiments were undertaken to examine the influence of Mn and Ca on H+ and combined H+/Al toxicity to the amphipod Hyalella azteca in synthetic inorganic media. Aluminum concentrations of 0.25 and 0.40 mg∙L−1 at pH 4.8 and 0.40 mg∙L−1 at pH 4.3 significantly increased the rate of mortality compared with reference Al concentrations of 0.05 mg∙L−1 at these pH values. Concentrations of Al as high as 0.70 mg∙L−1 did not ameliorate H+ toxicity at pH 4.0. Toxicity was always dominated by the H+ effect. Variation in neither aqueous Ca concentration from 0.5 to 4.0 mg∙L−1 nor Mn from 0.10 to 0.40 mg∙L−1 had any significant effect on the survivorship of H. azteca exposed to lethal treatments of H+ and Al (pH 4.0–5.3; [Al] = 0.25–0.70 mg∙L−1). We predict that mortality of this amphipod from springmelt pulses will be determined primarily by [H+], and secondarily by [Al] (but only in the pH range 4.3–5.3), and will occur independently of any accompanying changes in [Ca] or [Mn].


The supply voltage frequency effect on partial discharge (PD) phenomena has continued to draw research interest. Although most high voltage equipment operates at power frequency (50/60 Hz), testing is often done at different frequencies for various reasons. Despite some agreements and inconsistencies for the research findings of PD activity's frequency dependence, there has been consensus on the recognition of the discharge mechanism parameters that influence how the supply voltage frequency affects PD activity. These parameters include statistical time lag, discharge area surface conductivity, and the residual charge decay. In this paper, a 3-capacitor model (ABC) is used to simulate how the changes in the discharge mechanism parameters influence PD characteristics as a function of the supply voltage frequency. The findings are that the phase-resolved partial discharge pattern (PRPDP) and PD repetition rate (PDRR) characteristics are more sensitive to variations in the probability of the seed electron availability at higher frequencies of the supply voltage. The opposite trend is observed for the cavity surface resistance. At lower resistance of cavity surface, the PRPDP and PDRR characteristics are more sensitive to changes in the supply voltage frequency than at higher resistances. The paper also confirms that incorporating equivalent resistances in the ABC model makes it more authentic than the model comprising of capacitors only.


The complete nucleotide sequence of the virB locus, from the octopine Ti plasmid of Agrobacterium tumefaciens strain 15955, has been determined. In the large virB-operon (9600 nucleotides) we have identified eleven open reading frames, designated virBl to virB1l. From DNA sequence analysis it is proposed that nearly all VirB products, i.e. VirBl to VirB9, are secreted or membrane associated proteins. Interestingly, both a membrane protein (VirB4) and a potential cytoplasmic protein (VirB1l) contain the consensus amino acid sequence of ATP-binding proteins. In view of the conjugative T-DNA transfer model, the VirB proteins are suggested to act at the bacterial surface and there play an important role in directing T-DNA transfer to plant cells. INTRODUCTION The pathogenic bacterium Agrobacterium tumefaciens genetically transforms plant cells by introducing a defined segement of DNA (T-region) from the tumor-inducing (Ti) plasmid into the plant genome (for recent reviews see 1, 2). Crown gall tumorigenesis results from the expression of T-DNA genes which encode enzymes for the production of the plant growth regulators auxin and cytokinin (3-5). Other T-DNA genes determine the production of certain specific compounds called opines in tumor cells (6, 7). The T-region does not encode functions for its transfer from the bacterium to the plant cell. In the Ti-plasmid the T-region is flanked by nearly indentical 24 bp direct repeats, which form the cis-acting signals necessary for transfer (8-10). T-region transfer is mediated by products determined by virulence loci located elsewhere on the Ti-plasmid and on the Agrobacterium chromosome. The chromosomal virulence loci (chvA, chvB, att and pscA or exoC) specify the attachment of Agrobacterium to plant cells (11-14). The octopine Ti plasmid virulence (vir) region contains at least seven operons encoding trans-acting products (15-19) which are required for plant cell recognition and T-DNA transfer. The Vir-products which are absolutely essential are encoded by the virA, virB, virD and virG operons, © I R L Press Limited, Oxford, England. 4621 Nucleic Acids Research while the products determined by virC, virE and virF are only necessary for tumor induction on certain plant species. Plant phenolic compounds such as acetosyringone and v,-hydroxyacetosyrin -gone specifically activate expression of the Ti plasmid vir-loci (20, 21) and trigger the T-DNA transfer process. Induction of vir-gene expression is regulated by proteins encoded by the virA and the virG locus (22,23). The VirA protein is an inner-membrane protein which most likely functions as a sensory protein for plant-signal molecules (24,25). The second regulatory component VirG is proposed to act as a positive regulatory protein which activates vir-gene expression (23,26). The two remaining vir-loci essential for tumor induction are virB and virD. A recent study of the virD locus shows that at least two proteins (VirDl and VirD2) of the virD operon are involved in T-DNA processing (27). Together, these VirDl and VirD2 proteins can induce a nick at a specific site within the T-region border repeats, which is followed by the generation of a single stranded T-DNA molecule (T-strand) in Agrobacterium. T-strand molecules are thought to be the T-DNA intermediates that are transferred to the plant cells during tumor induction (27, 28). The other locus essential for tumor induction is virB and comprises the largest vir-operon. However, to date no specific functions have been assigned to the virB locus. Recently, it was reported that three proteins encoded within the 5'-half of the virB locus are located in the cell envelope of acetosyringone induced Agrobacterium cells (29). Interestingly, the envelope localization of these VirB proteins suggests that they might be involved in the transfer of T-DNA across the Agrobacterium membrane to the plant cells. In this report, we studied the nucleotide sequence of the entire virB-operon of the octopine type plasmid pTi15955. The virB operon spans 9.6 kb as defined by transposon mutagenesis and contains 11 open reading frames (ORFs). Some of the VirB proteins, as deduced from the DNA sequence, are extremely hydrophobic. Two VirB proteins, namely VirB4 and VirB1l contain the sequence characteristics of mononucleotide-binding-proteins. These findings are in line with a possible structural role of the virB encoded protein products in the T-DNA transfer process. MATERIALS AND METHODS Materials Restriction endonucleases were purchased from either Promega Biotec or New England Biolabs and used according to suppliers recommendations. T4


This Collaborative Classroom Action Research (PTKK) aims to find out and get data on how to improve IPAS learning outcomes about the human visual system for grade V students of SDN Kawung Luwuk in semester 1 of the 2023/2024 academic year through the TPACK approach and Augmented Reality media.This research departs from the results of observations of the problems of grade V students at SDN Kawungluwuk, namely there are several concepts in the subject matter that are still considered difficult or abstract for students. This can be a challenge for educators in explaining the material effectively and ensuring students' understanding. The value of media effectiveness is obtained from the response of students or respondents when using the media and comprehension tests after getting the material of the human visual system and ecosystems with Augmented Reality media. Learning outcomes obtained by students in each cycle. In cycle I with the average value of learning outcomes obtained by 71 and in cycle II the average value increased to 85. As for the presentation of completeness in cycle I 63% and in cycle II reached 88% exceeding the predetermined research success indicator of 85%. Based on research that has been conducted by researchers at Kawungluwuk State Elementary School on the Application of the TPACK approach and Augmented Reality media to Improve Learning Outcomes of IPAS subjects, it is generally concluded that the application of the learning model has succeeded in providing an increase in learning outcomes in class V-A students of SDN Kawungluwuk.


One of the parameters influencing the performance of active control systems for the reduction of vibration or noise is the placement of the active components of the system (actuators) on the host structure. In active vibration control systems the actuators are normally placed following a criterion related to the kinetic energy on the structure, whereas in active noise reduction systems
they are placed taking into account a sound pressure related metric. This numerical study investigates the placement of point force actuators on a generic plate structure within an active structural acoustic control system. Two setups are tested: a plate radiating in free field, and a plate radiating into a rectangular cavity. In both setups the plate is excited in its first natural frequencies by an incident diffuse sound field. The optimal placements of the actuators on the plate determined for a
minimal sound power radiated in free field or a minimal acoustic potential energy radiated into the cavity are compared to the optimal actuator placements determined for a minimal mean loudness over the area of interest. The effect of the different actuator placements on the ttenuation of the dominant radiation modes is analysed. The possible benefits of using the psychoacoustic loudness as an actuator placement criterion are discussed.


Abstract : For the preparation of cyclic silametallaazanes of type 1 in particular those in which R is a reactive substituent such as H or CH2=CH, we required the corresponding bis(trimethylsilylamino) silanes. Such compounds, we found, could be prepared readily by a Me3Si-for-H rearrangement reaction first reported by Wannagat and Niederprum in 1961.


Metabolism of the heterocyclic amine carcinogen 2-amino-3-methylimidazo[4,5-f ]quinoline (IQ) was evaluated in mice with and without 40 mg/kg beta-naphthoflavone (BNF). Following an oral dose of 40 mg/kg 14 C-IQ, a 24-hour urine was collected. Metabolism was assessed by HPLC and metabolites were identified by electrospray ionization mass spectrometry. Three new metabolites were identified as 1,2-dihydro-2-amino-5-hydroxy-3-methylimidazo[4,5-f ]quinoline ( m/z 217, [M + H] + ), 1,2-dihydro-2-amino-5-O-glucuronide-3-methylimidazo[4,5-f ]quinoline ( m/z 393, [M + H] + ), and 1,2-dihydro-2-amino-5,7-dihydroxy-3-methylimidazo[4,5-f ]quinoline ( m/z 233, [M + H] + ). These metabolites represented 21 % of the total urinary radioactivity recovered. For BNF-treated mice, the abundance of metabolites observed was 5-O-glucuronide > m/z 217 > m/z 393 > 5-sulfate > m/z 233 > N-glucuronide > Demethyl-IQ > sulfamate. In control mice, metabolite urinary abundance was 5-O-glucuronide > Demethyl-IQ > sulfamate > N-glucuronide > m/z 217 > 5-sulfate. In liver slices from BNF-treated mice, synthesis of m/z 217 and 5-O-glucuronide was significantly reduced by ellipticine, a P450 inhibitor, while sulfamate synthesis was significantly increased and Demethyl-IQ unchanged. Liver microsomes from BNF-treated mice produced m/z 217 and Demethyl-IQ with the former inhibited by both ellipticine and furafylline,


Photo 1. Wintering flock of Icelandic Black-tailed Godwits roosting during the high-tide period. In winter, Icelandic godwits forage mostly in estuarine mudflats during the low tide and, in some sites, also forage on wet grasslands. The energy benefits vary greatly between different winter sites. Photo by Graham Catley. The study explored fitness inequalities of energetic trade-offs on Icelandic Black-tailed Godwits wintering across the range. The conditions experienced by Icelandic Godwits (Limosa limosa islandica) at wintering locations throughout their range vary greatly, with important consequences for individual fitness. The costs of thermoregulation and low food availability on some sites can result in a negative energy balance, which is associated with low survival, later arrival in Iceland, and use of poorer-quality breeding sites, even when migration distance and costs are half those of conspecifics from more favorable winter sites.

We motivate, describe and demonstrate a generic repository for visual material related to cultural disciplines such as architecture, art and heritage. The repository design abstracts from the requirements of particular tasks to implement a set of common features based on the metaphor of a gallery. In functional terms, galleries are spaces in which several roles play together to create the larger social entity we call a gallery. Curators organize and interpret collections. Exhibitors contribute and interpret collection material. Through their commentary, Critics relate Resources and Exhibition. Viewers visit galleries to read and make their own interpretations of the content therein. Our design provides for each of these roles and implements them as actions on five fundamental types of objects: Resources, Exhibitions, People, Works and Annotations. We describe the architecture of a system called A•VI•RE that supports the above four roles and five object types. Included in this design is a meta-metadata scheme that supports variation in descriptors across content types. A•VI•RE's implementation is based on the open-source web portal system TikiWiki, providing opportunities for customization and integration with other open-source efforts. We describe a set of initial authoring styles for A•VI•RE Exhibitions. The paper concludes with hypotheses about the social and intellectual opportunities provided by the A•VI•RE functionality.


Purpose Elevated levels of the inflammatory marker interleukin-6 (IL-6) and cardiac injury marker N-terminal pro-B-type natriuretic peptide (NT-proBNP) have been observed in patients with coronavirus disease 2019 (COVID-19). However, the relationship between IL-6 and NT-proBNP levels remains unclear. Therefore, we investigated the relationship between IL-6 and NT-proBNP levels in patients with COVID-19. Patients and Methods This was a cross-sectional study. Consecutive patients with COVID-19 were included herein. The independent and dependent target variables were the IL-6 and NT-proBNP levels, respectively, measured at baseline. Univariate and multivariate linear regression analyses and curve fitting were also performed. Results The average age of the 121 selected participants was 49.8 ± 15.8 years old, and 48.8% (59/121) were male. The estimated β value between Ln-transformed IL-6 and NT-proBNP was 0.28 (95% confidence interval [CI] 0.12–0.44, P = 0.001) in univariate logistic regression analysis and 0.09 (95% CI −0.04–0.21, P = 0.176) in the fully adjusted model. This relationship was nonlinear, with a point of 2.7, and the β values (and CIs) for the left (<2.7) and right (≥2.7) sides of the inflection point were −0.06 (95% CI −0.23–0.12, P = 0.534) and 0.77 (95% CI 0.18–1.37, P = 0.016) in the fully adjusted model, respectively. Conclusion Our results suggest a nonlinear association between IL-6 and NT-proBNP levels. Higher IL-6 levels are associated with NT-proBNP in patients with COVID-19.

Introduction: lab studies are highly used to analytically course of cirrhosis. Objective: to evaluate the existence or absence of relationships between analytical tests and better or worst evolution in cirrhotic patients. Method: an observational descriptive study was carried out in cirrhotic patients admitted to Vladimir I. Lenin Hospital, from January 2011 to September 2011. The sample was intentional and comprised 41 patients whose clinical records matched the requirements of the study. They were classified in two groups of worst or better course according to clinical and echographic variables: results at the time of hospital discharge, hepatic encephalopathy, abundant ecographic ascites, history of upper gastro intestinal variceal bleeding, and decreased ecographic liver size. The value of aminotranferases, prothrombin time, and bilirubin were selected for the analysis, and the D'Reetis' quotient and Maddrey score were also obtained. Results: twenty five patients (61%) had worst course, and significant higher values of bilirubin and D'Reetis quotient (p=0.002 and 0,000 respectively). Having two altered tests was significantly associated with patients ́ worst course (p=0,035), related to the hyperbilirubinemia plus elongated prothombin time pattern, (p=0,002). An altered Maddrey score was associated to a worst course in alcoholic cirrhosis (p=0,000). Correo Científico Médico de Holguín Estudios analíticos y criterios de evolución clínico-ecográficos en pacientes cirróticos ingresados 216 Conclusions: hyperbilirrubinemia with elongated prothombin time, in all patients, and an increased Maddrey score in alcoholic etiology seem to be related to a worst outcome in patients hospitalized due to liver cirrhosis. Prospective studies to prove the validity and the likely use of this score in the clinical context are necessary to carry out.


The syndrome of multiple progressive intracranial arterial occlusions in young people, previously reported in the Japanese literature, has recently been described as occurring in the United States. We report the case of a patient with the typical combination of psychiatric, neurologic, and ophthalmologic manifestations which makes this syndrome an entity that may be referred to the ophthalmologist for evaluation. Possible reasons are discussed for the unusually high ophthalmodynamometry values observed in our patient.


The whole‐head of infant kittens was irradiated with fractionated doses of 150 R and 200 R at different postnatal intervals. Experimental age conditions consisted of an irradiated newborn, 1‐week, 2‐week, 3‐week, and a 4‐week age condition while the age of sacrifice remained constant at 70 days. The molecular layer thickness was reduced by 47% in the newborn, 40% in the 1‐week group, 17% in the 2‐week group, 19% in the 3‐week group and by 9% in the 4‐week group. An evaluation of Golgi impregnated material revealed that the dendritic arborizations of Purkinje cells were consistently reduced the earlier the age at which radiation was begun. A reduction in spiny branchlets was seen in all of the experimental conditions. All experimental age conditions displayed the phenomenon of dendritic "damming" at the pial surface, which consisted of an excessive crowding of spiny branches at this level. An increased growth of the primary dendrite before branching tood place was seen in the newborn and 1‐week group. This became less but was still significant in the 2‐week group. A correlation of this phenomenon with the presence or lack of stellate cells is discussed. Purkinje cells with two or more dendrites emerging from their soma were classified and analyzed separately. It was found that the primary dendritic branching in these cells often followed separate morphological patterns and appeared to be independent of each other. Climbing fibers were found to conform to the abnormal dendritic arborizations of the Purkinje cells, and were reduced in complexity in the early radiation treatment groups. This suggested that climbing fibers had no influence upon the dendritic growth pattern, but instead were under the influence of the Purkinje cell dendritic growth.


Background Osteoporosis and fractures increase morbidity and mortality rates after solid organ transplantation (SOT), but few studies have analyzed the risk of osteoporosis and related fractures after SOT. In this retrospective cohort study, we investigated the risk of osteoporosis and fractures in different SOT recipients. Methods This study was a retrospective cohort study using a nationally representative database in Taiwan. We collected the data of SOT recipients and used the propensity score matching method to obtain a comparison cohort. To reduce bias, we excluded patients who had been diagnosed with osteoporosis or fracture before inclusion. All participants were followed up until the date of diagnosis as having a pathological fracture, death, or the end of 2018, whichever occurred first. The Cox proportional hazards model was used to investigate the risk of osteoporosis and pathological fracture in SOT recipients. Results After adjustment for the aforementioned variables, SOT recipients were observed to have a higher risk of osteoporosis (hazard ratio (HR) = 1.46, 95% confidence interval (CI): 1.29–1.65) and fracture (HR: 1.19, 95% CI: 1.01–1.39) than the general individuals. Among the different SOT recipients, the highest risk of fractures was noted in heart or lung transplant recipients, with a HR of 4.62 (95% CI: 2.05–10.44). Among the age groups, patients aged >61 years had the highest HRs for osteoporosis (HR: 11.51; 95% CI, 9.10–14.56) and fracture (HR: 11.75, 95% CI: 8.97–15.40). Conclusion SOT recipients had a higher risk of osteoporosis and related fractures than the general population, with the highest risks observed in patients receiving heart or lung transplants, older patients, and patients with CCI scores of >3.


Various 1,3-diaryl-2-arylethynyl-1,3-butadienes 7 have been prepared by the Pd-catalyzed trimerization of arylalkynes 4. Their structures and stereochemistry have been confirmed by X-ray crystal analyses. This procedure provides high regioselectivity to generate adducts Z-7 in moderate to excellent yields. The scope, limitations and regioselectivity of this reaction have been investigated. In DMSO at 180 °C, 1,3-di(1-naphthalenyl)-2-(1-naphthalenylethynyl)-1,3-butadiene (7m) underwent 6π-electrocyclization to form 2-(1-naphthalenyl)-3-(1-naphthalenylethynyl)-1,2-dihydrophenanthrene (21). Under acidic conditions, (1Z)-1,3-diphenyl-2-(1-phenylethynyl)-1,3-butadiene (Z-7a) was converted to 1-methyl-3-phenyl-2-(2-phenyl-1-ethionyl)-2-indene (22) in 75% yield.


Fault tolerance in information security devices is difficult to establish due to the large number of possible interactions in the device (e. g. embedded code, boolean logic, electromagnetic interference, etc.) In previous work we examined information flow as a graph problem by composing orthogonal views of the device under analysis. In other work we used fault-tree analysis to reason about information flow as a systemic failure arising from certain configurations (or faults) in either the control logic or data flow 'backbone'. In this paper we combine these approaches by taking advantage of an alternative representation of fault trees as reliability block diagrams.


Chaos in discrete fractional maps has been reported very recently. In this study, the chaotic time series of fractional order is used in the scrambling technique and a novel image encryption scheme is designed. The fractional difference order and the chaotic coefficient play crucial roles in controlling chaotic behaviors. The encrypted results are analyzed, which shows that the encryption scheme is highly secure.


Context Pre-slaughter transport, exposed broilers to various stressors, which resulted in detrimental effects on animal welfare, live bodyweight loss, mortality and meat quality. There was growing interest to explore effective ways to reduce the stress response and improve meat quality of transported broilers by using dietary feed additives. Aims The purpose of the present study was to investigate the effect of chitosan oligosaccharides (COS) on meat quality, muscle energy metabolism and anti-oxidant status of broilers having 3-h transport stress. Methods In total, of 144 35-day-old broilers were randomly allocated to two dietary treatments, including a basal diet (96 broilers), or basal diet supplemented with COS at 200 mg/kg (48 broilers). There were eight broilers per cage, and 12 replication cages in the basal diet group and six replication cages in the basal diet with 200 mg/kg COS group. At the end of the experiment, after a 12-h fast, broilers in the basal diet group were randomly divided into two groups, with six replication cages in each group; then, the broilers were transported as per the following protocols: broilers in the basal diet group (CON group) were without transport stress; broilers in the basal diet group with 3 h of transport stress (TS group), and broilers in the basal diet with 200 mg/kg COS supplementation and 3 h of transport stress (TSC group). The serum corticosterone concentration, serum, liver and muscle anti-oxidant status, as well as meat quality and muscle energy metabolism were analysed. Key results Compared with the CON group, TS group showed increased bodyweight loss, serum corticosterone concentration, breakdown of muscle glycogen, increased muscle lactate dehydrogenase activity, as well as some changes of body anti-oxidant status (higher serum, liver and muscle MDA concentrations, lower serum SOD and GSH-Px, liver SOD and CAT, and lower muscle SOD, GSH-Px, and CAT activity), accompanied with lower pH45min and pH24h. Nevertheless, compared with the TS group, dietary COS supplementation reduced bodyweight loss, decreased muscle MDA concentration, increased muscle SOD and CAT activity, and was accompanied with improving pH24h. Conclusions The results suggested that the positive effects of dietary COS supplementation in maintaining meat quality were mainly due to the improved muscle anti-oxidant status. Implications Dietary supplementation with 200 mg/kg COS could serve as a beneficial and effective way to alleviate transport-impaired meat quality of broilers.


Although pollen‐related food allergy occurs in all European populations, lipid transfer protein (LTP) allergy is considered to manifest mainly in Mediterranean countries. We aimed to characterize adults presenting with LTP allergy in a northern European country.


The temperature-jump relaxation method has been used to measure the kinetics of formation of the 1:1 complex between magnesium and 8-hydroxyquinoline (oxine), and the magnesium-uramil NN diacetate, -adenosine 5′ triphosphate and -polytriphosphate complexes have also been investigated. In all cases the data are consistent with a two-path mechanism involving the addition to the magnesium species of the oxine anion or the oxine molecule. The first ligand has comparatively little influence on the rate at which magnesium reacts with a second ligand, and the kinetics of complex formation appear to follow the pattern already found for 1:1 complexes.
 These systems may be regarded as models for the enzyme-metal-substrate complexes which have been postulated as intermediates in many metal-catalyzed enzyme reactions. The observed rate constants are discussed in the context of a kinetic model to explain the differing catalytic powers of various metals such as magnesium and calcium.


Scientific misconduct potentially invalidates findings in many scientific fields. Improved detection of unethical practices like data fabrication is considered to deter such practices. In two studies, we investigated the diagnostic performance of various statistical methods to detect fabricated quantitative data from psychological research. In Study 1, we tested the validity of statistical methods to detect fabricated data at the study level using summary statistics. Using (arguably) genuine data from the Many Labs 1 project on the anchoring effect (k=36) and fabricated data for the same effect by our participants (k=39), we tested the validity of our newly proposed 'reversed Fisher method', variance analyses, and extreme effect sizes, and a combination of these three indicators using the original Fisher method. Results indicate that the variance analyses perform fairly well when the homogeneity of population variances is accounted for and that extreme effect sizes perform similarly well in distinguishing genuine from fabricated data. The performance of the 'reversed Fisher method' was poor and depended on the types of tests included. In Study 2, we tested the validity of statistical methods to detect fabricated data using raw data. Using (arguably) genuine data from the Many Labs 3 project on the classic Stroop task (k=21) and fabricated data for the same effect by our participants (k=28), we investigated the performance of digit analyses, variance analyses, multivariate associations, and extreme effect sizes, and a combination of these four methods using the original Fisher method. Results indicate that variance analyses, extreme effect sizes, and multivariate associations perform fairly well to excellent in detecting fabricated data using raw data, while digit analyses perform at chance levels. The two studies provide mixed results on how the use of random number generators affects the detection of data fabrication. Ultimately, we consider the variance analyses, effect sizes, and multivariate associations valuable tools to detect potential data anomalies in empirical (summary or raw) data. However, we argue against widespread (possible automatic) application of these tools, because some fabricated data may be irregular in one aspect but not in another. Considering how violations of the assumptions of fabrication detection methods may yield high false positive or false negative probabilities, we recommend comparing potentially fabricated data to genuine data on the same topic.

Objective
To evaluate natural reduction at prone position in the treatment of femoral subtrochanteric fractures with intramedullary nailing.

Methods
The clinical data of 7 patients with subtrochanteric fracture were retrospectively analyzed who had been treated at Orthopaedic Department, Beijing Tsinghua Changgung Hospital from August 2016 to April 2018. They were 4 males and 3 females, aged from 31 to 87 years (average, 55.6 years). Their fractures happened on the left side in 3 patients and on the right side in 4. By the Seinsheimer classification, there were 3 cases of type Ⅱ, 2 cases of type Ⅲ and 2 cases of type Ⅴ. The time from injury to surgery ranged from 9 to 44 hours, averaging 26 hours. All patients were treated by intramedullary nailing after natural reduction at prone position. Their preoperative preparation time, time required for reduction, total operation time, fluoroscopic frequency for guide pin insertion, fluoroscopic frequency for reduction, reduction quality, complications and curative effect were recorded.

Results
Closed reduction and intramedullary nail fixation were completed uneventfully in all the 7 cases. Their preoperative preparation time averaged 29.4 min (from 21 to 42 min), reduction time 6.3 min (from 3 to 10 min), and total operation time 157 min (from 82 to 275 min). Their fluoroscopic frequency averaged 37 times (from 14 to 96 times) for guide pin insertion and 23 times (from 10 to 49 times) for reduction, totaling 244 times (from 121 to 360 times). According to the modified Baumgaetner criteria, the fracture reduction was evaluated as excellent in 6 cases and as fair in one. The 7 patients were followed up for 12 to 34 months (mean, 20.1 months). A drill broke at the interlocking nail hole during operation in one patient, deep venous thrombosis occurred at a lower extremity in another during hospitalization, and fracture nonunion was observed after operation in another, but no complications related to the prone position were observed. The curative effect evaluated by Harris hip score at the last follow-up was excellent in 4 cases, as good in 2 cases and as fair in one.

Conclusion
In the treatment of femoral subtrochanteric fractures with intramedullary nailing, the prone position benefits natural reduction and maintenance of reduction and allows convenient fluoroscopy and nail placement during operation, especially for obese patients.

This paper aims to investigate the short and long term association between Foreign Direct Investment (FDI) and overall consumer affordability in Malaysia Real Estate Sector using Vector Autoregressive model. Sample period used is 2009:Q1 to 2017:Q4. FDI is scapegoated as the leading cause of decreasing affordability in real estate. In most cases, FDI on real estate contributes to the rising income of the country. Increasing income promotes demand to a higher threshold level. Thus, theoretically will cause housing price to increase. Through this study, evidence of no cointegration and absence of Granger causality converge towards deficiency of relationship among FDI and Housing Affordability Index (HAI). Findings pointed out FDI is not the cause of decreasing HAI.


Donors who falsely react in any of the transfusion microbiology screen tests are sent a standard letter and asked to give a sample after a suspension of twelve weeks [84 days]. The donors can then be considered for re‐entry to the active panel. We are not aware of any work showing how many donors re‐attend to give samples and how soon, so have analysed our national figures. 1301 donors who donated in the 3 months from 1st Oct 05 [434 per month] gave a false positive reaction and were sent the standard letter. 2269 donors returned in the period 1st Jan 06 to 31st May 06 [453 per month] following the standard letter and gave samples to be considered for re‐entry. Of these: 769 had donated in the 3 months from 1/10/05, 393 females and 376 males. The average number of days between initial and repeat samples was 130 days for females and 129 days for males with standard deviations of 27.4 and 27.9. Two donors attended and were sampled at less than 84 days! We recorded a maximum time interval between sample and donation of 231 days ‐ with each testing centre having donors attending at over 150 days. 755 donors were returned to the active panel [400 using the alternative assay re‐entry algorithm]. We have shown that 59% of false positive donors have given further samples for re‐entry. The figure is constrained by the length of time for which data is currently available. It may be higher if data were available for a longer period. When more data are available it may be possible to investigate how many false positive donors do not return and compare the results with those for first time donors, currently approximately 30%.


The apical portion of the cauliflower inflorescence has a high DNA content. Soluble chromatin can readly be isolated, showing that the apical portion is a suitable source for the mass preparation of isolated chromatin. Two methods for the determination of the histone content of isolated chromatin were used. RNA synthesizing capacities were also examined. The degree of template activity does not depend on amount of histone estimated in the TCA-precipitate, but does depend on the amount of histone determined in chromatin in the soluble state. Condensed- and extended-chromatins were separated and extended chromatin had four times as high template activity as did condensed chromatin.


A reflectionless termination design is described which, in principle, can be adapted to wave‐guide or coaxial transmission lines. Reflection coefficients of 0.001 were obtained experimentally with X‐band wave‐guide terminations. The termination comprises a section of transmission line into which is fitted a tunable sliding load. The sliding load is tuned to be reflectionless by means of the ``sliding load'' method of measuring reflection coefficients. The termination can be operated over a wide frequency range but must be retuned each time the frequency is changed.The wave‐guide circuit of the load is analyzed and design equations are derived.The reflectionless wave‐guide termination is primarily useful as a reference standard for microwave impedance bridges.


The microwave extraction of polysaccharide from Zizyphus Jujuba in North Shanxi was studied with deionized water as the extracting agent. Based on the yield and content of polysaccharide, a series of test on single factor affecting the extraction of polysaccharide were carried out, including microwave time , microwave power and pH value. Following the results of these tests and using orthogonal test method, we determined the optimal extracting conditions as follows: microwave time is 4 minutes, microwave power 480 watts, pH value is 6.6. The comparison between microwave extraction and traditional ways showed that the method of microwave extraction is effective and easy to operate.


Abstract: Accurate monitoring of land surface dynamics using remote sensing is essential for the synoptic assessment of environmental change. We assessed a Medium Resolution Imaging Spectrometer (MERIS) full resolution dataset for vegetation monitoring as an alternative to the more commonly used Moderate-Resolution Imaging Spectroradiometer (MODIS) data. Time series of vegetation indices calculated from 300 m resolution MERIS and 250 m resolution MODIS datasets were analyzed to monitor vegetation productivity trends in the irrigated lowlands in Northern Uzbekistan for the period 2003–2011. Mann-Kendall trend analysis was conducted using the time series of Normalized Differenced Vegetation Index (NDVI), Soil-Adjusted Vegetation Index (SAVI), and MERIS-based Terrestrial Chlorophyll Index (MTCI) to detect trends and examine the capabilities of each sensor and index. The methodology consisted of (1) preprocessing of the original imagery; (2) processing and statistical analysis of the corresponding time series datasets; and (3) comparison of the resulting trends. Results confirmed the occurrence of widespread vegetation productivity decline, ranging from 5.5% (MERIS-MTCI) to 21% (MODIS-NDVI) of the total irrigated cropland in the study area. All indices identified
