A system and method may determine a source of inefficiency a reduction of nitrogen oxide in an exhaust gas system having a first and second selective catalytic reduction (SCR), which are connected in series along an exhaust pipe. The methods and systems can determine which of the first and the second SCR catalyst is a source of inefficiency for nitrogen oxide reduction based on the temperatures of the exhaust gases flowing through the first and second SCR catalyst.


This essay is an attempt in analysing the establishment of the first Early Middle Ages castles in Scania. There are two types of castles in Scania during the eleventh century, keeps and

ringworks. This castle was built by three fixed elements of power: the crown, the church and the aristocracy. The result of the survey shows that A majority of the castles during the

eleventh century in Scania where initiated by the church.

The results also show two building phases of castles under the period. The first building phase begins in middle of the eleventh century and the second building phase begins in the

period 1180- 1200. Archaeology and historical sources indicates that the castles where not primarily used for military purpose, they also hade economical functions.


The alignment of inertial measurement units(IMUs) to segment is an important step in inertial motion capture, which directly affects whether the imu data can fully represent the motion of the segment. Inspired by the gene crossover and mutation of Genetic Algorithm(GA), we propose a dynamic inertial weighted particle swarm optimization algorithm with cross factor to solve the joint constraint problem, and compared our algorithm with Particle Swarm Optimization(PSO) and Dynamic Inertial Weighted Particle Swarm Optimization(DPSO) algorithms to show the superiority of our algorithm during human lower limb movements. The experiment shows that introduced the random cross mechanism between particles with larger fitness and only the effective cross retained, makes the new algorithm show better search ability and convergence effect in this project, the stability and effectiveness are also improved. Our current work provides a good support for accurate calculation of joint angles in the future.


Pre-clinical studies form the foundation for pharmacology and therapeutics in humans. There have been recent calls for pre-clinical studies in aged animals and in both male and female animals to better reflect the older people who are commonly treated. There are opportunities to test effects of real life exposures in aged animals to inform therapeutics. For example, short term treatment with therapeutic doses of five commonly used medicines (polypharmacy) impairs physical function in aged but not young adult male mice. Objective models of important outcomes for older people, such as healthspan and frailty, have recently been developed. These are being measured as outcomes of treatments for disease or aging itself in pre-clinical studies, with differential effects observed by sex. The effect of frailty on pharmacokinetics, pharmacodynamics and toxicity of commonly used medicines (e.g. acetaminophen) is now being investigated in frail animals, to guide treatment of frail older people.


Direct conversion of fructose into 5-hydroxymethylfurfural (HMF) is achieved by using modified aluminum-molybdenum mixed oxide (S-AlMo) as solid acid catalysts. The synthesized catalyst was characterized by powder XRD, nitrogen adsorption-desorption isotherm, NH3-TPD, and SEM. As a result, the presence of strong acidity, mesostructures, and high surface area in the S-AlMo catalyst was confirmed by nitrogen adsorption-desorption isotherm and NH3-TPD studies. A study by optimizing the reaction conditions such as catalyst dosage, reaction temperature, and time has been performed. Under the optimal reaction conditions, HMF was obtained in a high yield of 49.8% by the dehydration of fructose. Moreover, the generality of the catalyst is also demonstrated by glucose and sucrose with moderate yields to HMF (24.9% from glucose; 27.6% from sucrose) again under mild conditions. After the reaction, the S-AlMo catalyst can be easily recovered and reused four times without significant loss of its catalytic activity.


The possibility of creating alternative air-conditioning systems on the basis of open absorption cycle (dehumidification of air by a liquid absorbent, evaporative cooling, solar regeneration of the absorbent) is discussed in the paper. Presented are the main schematic solutions and the analysis of open absorption system possibilities.


Taking the first draft of Chinese majors' undergraduate theses in Hebei North University as an example,the article enumerates some problems about topic,subtitle,and the overlap,cross,inversion,being disjointed,jumping,and confusion of concepts.Aiming at these problems,the paper points out that strengthening the scientific guidance in the use of concepts is an important approach to improving the effectiveness of undergraduate thesis and concretizes this approach into four kinds of consciousness or habits:scientific knowledge of styles and their discourse features,research consciousness of logics,scientific understanding of that words are concepts,and good habits of orderly thinking.All this should be based on the idea that literature is also science.

This study investigates the building damage in Mashiki Town, Kumamoto Prefecture, Japan, due to the 16 April 2016 Kumamoto earthquake. The result of damage investigation by the local government is analyzed from the view points of structural material and construction period. As a result, the damage ratio of wooden buildings was much higher than that of steel, light-gauge steel, and RC buildings. The damage ratio of wooden buildings gets higher as the construction period becomes older. Within the construction period of 1982-2016 that corresponds to the new seismic code in Japan the damage ratio becomes smaller for newer wooden buildings. The spatial distribution of damaged buildings is further investigated with their location information on GIS. Compared with an estimated PGV distribution, the result of this study will be used for the development of vulnerability functions of Japanese buildings.


In patients with obstructive colorectal cancer, it is difficult to evaluate the oral site of the large bowel by colonoscopy. Instead of colonoscopy, previous studies have shown that computed tomography (CT) colonography is effective for detection of neoplastic lesions in the large bowel. In the present case, we carried out CT colonography and found superficial early cancer at the oral side of the obstructive cancer, and carried out surgical resection for both lesions. A 60‐year‐old man was admitted with complaints of abdominal pain and distension. Total colonoscopy could not be carried out because of the stricture of the lesion. To evaluate the proximal site of the large bowel, we carried out CT colonography, which showed a superficial lesion in the transverse colon suggestive of early cancer. He underwent surgery and an intraoperative colonoscopy of the transverse colon, which confirmed the findings of the CT colonography. The patient underwent R0 resection for both an advanced lesion and a superficial lesion. Pathological examination of the superficial lesion showed adenocarcinoma‐invading submucosa. The postoperative course was uneventful and the patient was discharged a week after the operation. The present case suggests the importance of CT colonography for patients with obstructive colorectal cancers to detect synchronous neoplastic lesions, including superficial early cancers.


The Bar-Natan homology is a perturbation of the Khovanov homology of a knot. Previous work has shown that Khovanov homology remains unchanged under Conway mutation of the knot diagram. We give an exact triangle with three different resolutions of a link and prove several lemmas relating the dimensions of different Bar-Natan chain complexes and homologies. These allow us to prove that the dimension of the Bar-Natan homology BN(L;Z/2Z) is invariant under Conway mutation.


The embryological basis of spina bifida and the associated doubletailed condition has received a number of explanations. Hertwig 1 advanced the basic theory that the bifid condition results from inhibition of gastrulation which retards closure of the blastopore and thereby prevents fusion of the anlagen of the axial organs located on either side of the blastopore. Berge 2 followed Hertwig, attributing bifid tails to a persisting blastopore which mechanically blocks the tail anlagen. Baldwin, 3 studying the effects of ultraviolet irradiation upon frogs′ eggs, concluded that the essential factor was injury to the highly susceptible yolk material (endoderm), which serves as a barrier to the approximation of the blastoporal lips. Bellamy 4 suggested inhibition of the dorsal blastoporal lip, which is a region of high susceptibility to a variety of noxious conditions. This study is a preliminary report of attempts to determine whether injury to one or more specific regions of the egg is responsible for the bifid condition of the lower back and tail, or whether it is produced by general injury to the egg. Localized sublethal injuries were produced easily by means of ultraviolet irradiation. A cold quartz burner∗ was used whose spectrograph shows a high proportion of rays at 2537 A. U. The intensity was such that after irradiating early gastrulae for 13 minutes there was no trace of a neural plate within 24 hours. Most of the egg-jelly was removed with scalpels. The eggs were placed in a chamber the bottom of which was a quartz plate 1.65 mm thick. Irradiation was from below, with the ultraviolet burner 2.5 mm from the lower surface of the quartz plate. Shields cut from tinfoil were applied closely to the surface of the egg to protect all except the irradiated region.


A sharp decline in the Sediment load at the seaward most Datong station (DTS) of the Yangtze River occurred at an average rate of 7.22 × 106 t/yr since 1956, and this drop had a staircase pattern that can be divided into five distinct periods (1956–1968, 1969–1991, 1992–2002, 2003–2012, and 2013–2017). In this study, a new holistic basin‐wide Sediment Budget Method (SBM) was developed using sediment data from a total of 74 gauging stations (arguably the largest datasets so far) to estimate the sediment contributions to DTS from tributaries and mainstream. Our results show that the Jinsha River in upper basin between Panzhihua and Xiangjiaba used to be one of the largest contributors to DTS in 1956–2002 (16%–33%), but its contribution decreased sharply after 2003 due to the impoundment of Three Gorges Dam (TGD) and decreased further to nearly nil in 2013–2017 due to the impoundment of new cascade dams (CDs) which were upstream of TGD. In contrast, the mainstream between Yichang and Datong contributed 50%–64% of the DTS in 2003–2017, owing to the active channel erosion downstream of TGD. Before 2003 about 66%–84% of the DTS was contributed by the upper reach, but 72%–91% of the DTS was from the middle‐lower reaches after 2003, reflecting a drastic shift in sediment suppliers from upper to middle‐lower reaches. On average, the drop of DTS was 128.37 × 106 t/yr due to TGD impoundment in 2003–2012 and 27.28 × 106 t/yr due to CDs impoundment in 2013–2017 because of the reservoir trapping and the inhibition of historically eroding channels in the reservoir area. This new SBM can be applied to other large and small rivers around the world to track sediment sources/sinks and provide valuable results for sediment resource management.

The seismic response of the twelfth-century Byzantine church of Panhagia Krina in Chios, Greece, is investigated in this paper. The numerical model implements all the details of the geometry of the structure and is validated by comparison of the dynamic characteristics with ambient vibration measurements. Time-history elastic analyses are performed for selective seismic motions, chosen to comply with the expected ground motion in the area. The results show that the linear elastic approach can predict the existing damage quite accurately and explain the collapses that occurred during the 1881 earthquake. The effectiveness of several interventions is also examined; in some cases, cracks were introduced in the model to overcome the limitations of the elastic analysis. The proposed interventions enhance the structure but they cannot eliminate the possibility of severe damage or even local collapses during future seismic events. This is because there are inherent problems in the structure, e.g., the large size of the dome of the main church compared with the overall size of the structure and the structurally weak system of support of this dome.

about issues of power and social justice. "One thing about these books is that I can hear a pin drop when I'm reading them to my class," reports Lee Heffernan, who teaches third grade at the Childs School in Bloomington, Indiana. The "pin drop" description is supported by a videotape shared with us by Sheilah Lyles, a first-grade teacher from Indianapolis. Although the children were noisy and inattentive as their teacher began to read aloud, the change in their demeanor was dramatic as she got further into the book White Wash (Shange, 1997). Within a few minutes, the wiggling had stopped and the children were clearly focused on the pictures and their teacher's voice. This was surprising to Ms. Lyles, who later commented that showing such rapt attention during a read aloud is a rare occurrence for these children. In both cases, the teachers were reading books from an evolving text set that provides a framework for a new kind of "critical literacy" curriculum which focuses on building students' awareness of how systems of meaning and power affect people and the lives they lead. These books invite conversations about fairness and justice; they encourage children to ask why some groups of people are positioned as "others." According to the definition we developed, critical books meet one or more of the following criteria:


We prove that each simple polygonal arc {\gamma} attains at most two pairs of support lines of given angle difference such that each pair has s1 < s2 < s3 that {\gamma}(s1) and {\gamma}(s3) are on one such line and {\gamma}(s2) is on the other line.


Quite simple interferometric method based on the multi-fringe optical Fourier transform technique is suggested in this article. This method offers a specific and precise technique for the study of highly oriented fibers that produce two or more fringes in the marginal zone of the exit pupil of the microscope objective. The measuring accuracy of the direct initial interference order and the current interference orders in the image of highly oriented polymeric textile fibers is increased.


The invention discloses two-camera based object mass measuring method, device and terminal. The method comprises the steps of acquiring an image of the object to be measured through the two cameras; calculating the size of the object to be measured according to the shape of the object to be measured in the image and the parameters of the two cameras during acquiring the image of the object to be measured; acquiring the density of the object to be measured to obtain the mass of the object to be measured. According to the method, the two-camera technology is adopted to measure the object size, and then the size of the object can be calculated according to the object size; therefore, the object mass can be obtained after obtaining the object density; the method can be applied to a two-camera including terminal, and therefore, a user can carry conveniently, and the user experience effect is improved.


Oil painting is the process of painting with drying oils as binders. Such oils mainly consist of triacylglycerols characterized by high levels of unsaturated fatty acyl chains. For instance, poppy seed oils have received much attention for their use as oil paints since very ancient time. Upon exposure to oxygen, not only do drying oils harden to a densely cross-linked polymer network through radical reactions, but their fatty acids also interact with cations of some pigments forming the related carboxylate salts. These so-called metal soaps lead to severe degradation phenomena because they can migrate and aggregate, breaking through the surface of the paint. Since the fatty-acidome of a drying oil is involved in these processes, the current study is chiefly devoted to the identification of both free and total fatty acids in poppy seed oil by reversed-phase liquid chromatography coupled with high-resolution mass spectrometry by an electrospray ionization source (RPLC-ESI-FTMS). Total fatty acids (TFA) were investigated by enzymatic hydrolysis and comparisons were made between the free fatty acid (FFA) profile and the total one resulting from the digestion on the same poppy seed oil. A key component of our approach was the double bond (C=C) epoxidation reaction, which was carried out on unsaturated fatty acids by meta-chloroperoxybenzoic acid (m-CPBA). A chromatographic set up was developed to separate such oxidized lipids, that were identified as deprotonated molecules [epoM-H]− by accurate mass matching in full mass spectra. Their epoxide ring was subsequently cleaved upon tandem mass fragmentation to yield a pair of diagnostic product ions for C=C double bond localization. Interestingly, the double bond geometry (i.e., cis/trans) was also assigned based on the retention times of derivatized-FA. The present approach opens new avenues for the analysis of artworks whether affected by metal soap-related degradation phenomena.

Heparin requires antithrombin III (AT) to achieve anticoagulation, and patients on continuous small-dose heparin preoperatively experience decreased levels of AT-causing heparin resistance. When this occurs, 2–4 units of fresh frozen plasma (∼1000 units of AT) are often administered to increase AT levels and restore heparin responsiveness. We evaluated purified human AT concentrate (Thrombate III; Bayer, Inc., Elkhart, IN) to restore in vitro anticoagulation responses in patients receiving heparin. Blood samples were obtained from cardiac surgery patients including 22 patients receiving heparin and 21 patients not receiving heparin preoperatively. Heparin was added to blood in final concentrations of 4.1, 5.4, and 6.8 U/mL (equivalent to 300, 400, and 500 U/kg), and kaolin-activated clotting times (ACTs) were determined with and without AT at a final concentration of 0.2 units/mL to mimic fresh frozen plasma administration. The mean duration of preoperative heparin therapy was 4.0 days (range 2–10 days). AT activity was 69% ± 9% in patients receiving heparin and 92% ± 8% in patients not receiving heparin (P < 0.01). Heparin >4.1 U/mL failed to further increase ACT values in all patients. Attempts to increase ACT in patients receiving heparin may require supplemental AT administration. Purified AT even in small doses significantly prolongs the ACT response to heparin. Implications In vitro addition of antithrombin III (0.2 U/mL) to heparinized blood samples (4.1–6.8 units of heparin/mL) from patients on previous heparin therapy increases sensitivity to supplemental heparin as reflected by significantly prolonged activated clotting time.


The influence of physical exercises on health components of the quality of life of students is discussed. It is found that physical and mental component indicators of the quality of life of students who do yoga are much lower than those of students practicing kickboxing. The level of mental health component is lower than the level of physical health component. The obtained results indicate the psycho-emotional condition and existence comfort during the investigation. Statistical correlations between the quality of life indicators are determined and discussed.


The electric field vectors associated with telluric currents are known to vary in relative magnitude and principal direction at different locations. A number of temporary recording sites were occupied in the College, Alaska, region, where telluric currents have been recorded routinely since 1955. The results of this study show that the relative magnitude may change by a factor of 5 and that the principal direction may range over 33° and in one extreme case 70°, in the area of radius 10 miles from the Geophysical Institute. Model studies using a two-dimensional resistor network were made to determine the effects of some simple topographic and conductivity configurations on the telluric field.


To the Editor.—
 Snyder1 found that the reported use of glucose-electrolyte solutions by pediatricians was not in accordance with the American Academy of Pediatrics Committee on Nutrition's recommendations on oral rehydration therapy (ORT) for acute diarrhea. To determine actual physician practices, we conducted an audit of diarrhea management, including use of ORT, in the Emergency Room of our pediatric hospital. Our 4-month audit period included an epidemic of viral gastroenteritis, during which we expected to see optimal case management.


The newly practiced basic education curricula reform has its own basic objectives, characteristics and four'shifts', which challenge the present teacher education. It is urgent to foster qualified teachers who are humanbased, guiding and promoting, cooperative, comprehensive, creative and researching. The teacher education should respond actively and explore the corresponding countermeasures.


"Red Elite" geraniums were grown from the 6th leaf stage until the visible bud stage in controlled environment (CE) chambers under 3 day/night temperature regimes (27°/13°, 23°/17°, or 20°/20°C) and under enhanced CO2 (900 μl CO2/liter air) at 27°/13°. Three daily light integral treatments, 24.6, 19.8, and 15.1 mol m−2 d−1, were imposed over each of these 4 treatments. Plants also were grown in a 22714° glasshouse with 2 daily light integral treatments (18.2 or 11.3 mol m−2 d−1). A chlormequat (CCC) drench was applied to half of the plants immediately before the treatments were started. For the period between the 6th leaf and visible bud stages, leaf area, leaf area ratio, specific leaf weight, shoot dry weight, leaf canopy height, and time to visible bud were determined mostly by daily mean temperature rather than by day or night temperature. Most plant growth characteristics, but not the flower bud development rate from 6th leaf to visible bud, were enhanced by supplemental CO2 and suppressed by CCC. After reaching the visible bud stage, plants from some treatments were moved into 24715° CE temperature conditions with or without CO2, whereas others were moved to a glasshouse until harvest at the 1st floret anthesis stage. Between visible bud and anthesis, CCC was the major factor affecting vegetative growth regardless of whether the plants were with or without supplemental CO2 in CE rooms, or in a glasshouse. Anthesis was delayed by about 10 days in the glasshouse compared to the CE treatments but was unaffected by CO2 or CCC treatments. Carbohydrate concentrations were highest (starch 14%, sugar 5%) in plant leaves grown with supplemental CO2 and without CCC, and lowest with no added CO2 but with CCC in all CE treatments. The concentrations were reduced (starch 0.5%, sugar 2.5%) in plant leaves grown in a glasshouse from 6th leaf stage to anthesis because of low daily light integrals and no supplemental CO2.


Our goal was to determine whether there is any correlation between the mRNA expressions of transforming growth factor β (TGFβ)-isoforms/their receptors and the fertility in chicken sperm stored in vitro for different times. The semen collected from White Leghorn roosters was divided into diluted (in Lake's solution) and undiluted groups, and stored for 0, 24, 48 and 72h at 37°C to observe sperm viability, fertility of the eggs after artificial insemination (AI) and mRNA expressions of TGFβs and TGFβ receptors (TβRs) in the sperm. Sperm viability was assessed using propidium iodide (PI) and egg fertility was observed by judging the development of embryo. The mRNA expressions of three types of TGFβ-isoforms (β2, β3 and β4) and three types of their receptors (TβR1, TβR2 and TβR3) in both the diluted and undiluted sperm were examined by semi-quantitative RT-PCR. Sperm viability in diluted semen declined slowly from 97% to 73% (75% declines against the initial value), whereas fertility was declined from 88% to 23% (26% declines against the initial value) by 72h of sperm storage. The mRNA expressions of sperm TGFβs and TβRs were also declined gradually during the storage of sperm. Correlation and regression analysis also showed a positive correlation between the sperm TGFβs/TβRs and fertility. In undiluted semen, egg fertility and the expressions of TGFβs/TβRs became negligible by 24h of storage, although 29% sperm were alive. These results suggest that expression of TGFβs and TβRs by sperm is one of the factors responsible in fertility, probably by maintaining the sperm survivability in the hen oviduct.


Arginine methylation (ArgMe) is one of the most ubiquitous PTMs, and hundreds of proteins undergo ArgMe in, for example, brain. However, the scope of ArgMe in many tissues, including the heart, is currently underexplored. Here, we aimed to (i) identify proteins undergoing ArgMe in human organs, and (ii) expose the relevance of ArgMe in cardiac disease.

This paper mainly discusses distributed constrained optimization problem for second‐order multi‐agent system under undirected communication network. The task of all agents is to minimize the sum of the local convex functions, where each agent is individual and only accesses to one objective function. Different from the most existing results, where the objective functions are assumed to be time‐invariable, this paper considers the situation of time‐varying objective function. Besides, we don't require that the Hessian matrices are identical and the gradients are bounded. First, a novel time‐varying optimization algorithm is proposed based on the projection algorithm. Second, by using convex analysis and Lyapunov theory, it is shown that the states of all agents can reach consensus and asymptotically converge to the neighborhood of the optimal solution. Finally, some numerical examples are given to verify the effectiveness of our algorithms.

In receiver design, how to select the frequency discriminator loop the loop filter carrier tracking loop is critical. Due to the Doppler frequency difference uncertainty exists, the carrier phase direct capture a greater degree of difficulty, but was able to capture the frequency quickly eliminate most of the effects of the Doppler shift, and then the tracking phase is relatively easy to get many.

In the present work, achiral non‐coded amino acids, N‐(Bzl)‐Gly, X1 or X2, were substituted at position 7 of the model B2 receptor antagonist [D‐Arg0, Hyp3, Thi5, 8, D‐Phe7]‐BK. The N‐terminal amino group of the analogues was either free or acylated with 1‐Aca or Aaa. Biological activity of the compounds was assessed in the in vitro rat uterus test and the in vivo rat blood pressure test. The X17 substitution resulted in a decrease in antagonistic potency of the new peptide in both assays. The X27 and N‐(Bzl)‐Gly7 substituted analogues showed weak agonistic properties in the rat uterus test. Interestingly, the latter compound exhibited dual activity in the pressor test, i.e. intrinsic vasodepressor action and at the same time a weak antagonistic effect. Acylation of the N‐terminus enhanced antagonistic properties of the resulting peptides in the rat blood pressure test in the case of compounds containing X1 or X2 modification. Our studies provide new information about structure–activity relationship of the BK antagonists which may be helpful for designing more potent B2 receptor blockers.

Abstract: The accumulation of the polyamine spermine into 0.1‐mm prisms of rat cerebral cortex has been investigated at both 37°C and at 4°C. Kinetic analysis of the temperature‐sensitive portion of uptake indicates two high‐aftinity saturable components together with an unsaturable component at high concentrations. The 'very high'– affinity saturable system (Km= 3.8 nM) was temperature‐ and sodium‐dependent, and significantly reduced by metabolic inhibitors, findings that are consistent with an active transport system for spermine into brain tissue. The 'high'– affinity saturable component (Km= 0.44 μM) was sodium‐dependent and inhibited by ouabain, but only partially susceptible to inhibition by 2,4‐dinitrophenol and sodium cyanide. The significance of these results with respect to the function of spermine in the central nervous system is discussed.


Reasons for the demographic transition that occurred in Europe are considered. Using historical Swedish data the author argues that the fertility decline that has occurred in Europe over the past 250 years is the result of homeostatic regulation. He points out that since population growth has not increased as fast as the food supply poverty and hunger in the developing world are therefore due primarily to the upheavals caused by social change and the obsolescing of traditional forms of livelihood.

A fuel cell system (101) is comprised of a power generating portion (5) having a plurality of laminated cells; a fuel supply portion (4) for supplying fuel to the cells, which can adjust the amount of fuel to be supplied; a voltage monitoring portion (8) for monitoring the output voltage of at least one specific cell (51) selected among the plural cells; a power supply portion (13) for temporarily supplying electric power to the specific cell; and a control portion (9) which detects a voltage difference between the minimum value of the output voltage occurring after electric power is supplied to the specific cell and the response value of the output voltage after the output voltage is reduced to the minimum value, and which controls the amount of fuel to be supplied in accordance with the voltage difference.


A lot of research is done on the impact of website design on site's performance. It includes use of CSS, applets, Ajax, etc. for improving the performance. However, interconnectivity between pages through hyperlinks and its impact on website performance and website structure is little explored. This aspect of a website design is explored in this paper. This brings out the time required to move from the current page to any other page of the website. Two metrics capturing the inter-page access based hyperlinks are proposed, and their relationship with the website structure and website performance is explored. The metric computation is illustrated with the help of dummy website. The impact of the website hyperlink structure on the performance is studied through six real websites from academic and e-Governance domain.


Michael Davidson's On the Outskirts of Form: Practicing Cultural Poetics contributes to the expanding field of twentieth-century poetic theory by reading the tradition of radical poetics through a cultural lens, with particular emphasis on globalization. Davidson's work spans the nineteenth and twentieth-centuries as well as the Black Mountain, Berkeley Renaissance, New York, and mainstream poetics. Authors considered include the contemporaries: Herbierto Yepez, Christina Rivera-Garza, Lisa Robertson, and Mark Nowak; the "New American" generation: Charles Olson, Edward Dorn, Robert Creeley, Robert Duncan, Denise Levertov, James Schuyler, and John Ashbery; as well as George Oppen, Lorine Niedecker, and even Percy Shelley.


The evaluation of precision and accuracy in " ' P u / ( " ' P u + " " ' P u ) a activity ratio determination is of paramount importance for calculating ' " P u in plutonium samples and for exploiting Isotope Dilution Alpha Spectrometry (IDAS) to establish the concentration of plutonium in the irradiated fuel dissolver Solution. This has been achieved by preparing synthetic mixtures with a activity ratios ranging from O.Ol to 10 using ' " P u and ' " P u isotopes. Sources were prepared from these mixtures by electrodeposition in an aqueous HNO3 medium and the a spectra were recorded by employing a solid State sihcon surface barrier detector coupled to a 4 K analyser. The validity of a simple evaluation method based on the geometric progression (G. P.) decrease for the far tail of the spectrum is demonstrated in the present work. It is concluded that an accuracy of 0.5% and a precision of ± 0.2% (1 o) can be reached in the determination of "»Pu / ( " ' Pu+"° Pu) cx activity ratio ranging from O.Ol to 10.


Research background: Numerous modern indicators are attempting to integrate better economic, political, social, and environmental ambitions to uncover potential synergy, trade-offs, and future views that center around the notion of a so-called green economy. As long as the various indicators are not bounded in one comprehensive measurement, utilizing knowledge of relevant information and statistics that are crucial for monitoring the progress will not give us answers on the progress towards green growth either. Without an adequate measurement framework and robust statistics, the evaluation of the green economy is open to subjective reasoning.
Purpose of the article: This paper aims to offer a strong standpoint for green topics by exploring the concept of Green GDP. The paper introduces a new, updated database on Green GDP for the set of 160 countries from 1970?2019.
Methods: This database is distinctive due to its balanced coverage of two components of the green economy: quantitative feature (standard methodological algorithm) and qualitative feature (opportunity costs) within a common Green GDP accounting framework.
Findings & value added: Standardizing new methodologies and procedures for estimating environmental costs with a statistical foundation provides added value, which we hope will support the creation of reliable accounting and valuation systems for the green economy on a developing "green platform."


We designed and synthesized novel organic dyes of double electron acceptor type based on phenothiazine framework, as photosensitizers for the dye-sensitized solar cell (DSC). The density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were used to estimate the photovoltaic properties of the dyes in the design stage. The molecular structure having two electron acceptors on both sides of phenothiazine moiety provided the efficient electron extraction paths from electron donor part, which was demonstrated by the analysis of the electronic structures on donor and acceptor, and the excitations between HOMOs and LUMOs. In accordance, the measurements of photovoltaic properties of the DSCs prepared in the laboratory scale showed that the organic dyes of double electron acceptor type gave about 20% higher performace than their counterparts of single electron acceptor type. The effect of the kind of electron acceptor (C, cyanocrylic acid and R, rhodanine-acetic acid) on t...


During the 2005 and 2006 excavations, an important stratigraphical sequence was explored in the area near the inside front of the protohistoric fortification walls (SAS IX). The ruins of three monumental huts with a rectangular plan superposed and occupied between the Recent Bronze Age 1-2 and the Final Bronze Age 2 were brought to light. A huge quantity of Aegean imports together with local hand-made pottery was found. The presence of many faunal remains in all the occupation layers lead us to think of celebrations of sacrifices and ritual meals.

The use of mobility performance measures is a practical way to evaluate congestion levels on highly trafficked roads, as it is based on parameters to which road users can relate such as travel time, delay and the reliability with these parameters can be estimated. A set of Mobility Performance Measures was formalised by the Texas Transportation Institute (TTI) between 2003 and 2005 to supplement the traditional Level of Service (LOS) approach [1] [2]. These performance measures are particularly useful as they are easy to interpret and require basic data as input which can usually be obtained from various sources. Because these measures are quantitative rather than qualitative, the improvement or deterioration of traffic conditions can be easily compared over time or between different road sections, corridors, road networks or even different transport modes. The feasibility of using mobility performance measures to assess traffic congestion in South Africa was investigated in 2008 [3]. As part of this study the performance of the Ben Schoeman Freeway between the Brakfontein and Buccleuch interchanges was assessed. The study found that by 2007 the majority of this road section performed dismally with the AM peak period spreading from 6h00 to 9h00 and traffic conditions classified as "intolerable" based on mobility performance analysis. Since then the Brakfontein-Buccleuch road section has been significantly upgraded as part of the Gauteng Freeway Improvement Project (GFIP) initiated by the South African National Roads Agency (SANRAL). The purpose of this paper is to assess the change in traffic conditions from before to after the implementation of the upgrades by calculating mobility performance measures from the latest traffic data. Key Issues that are discussed as part of this paper as follows: 1. Impact of improvements to the Ben Schoeman Freeway on mobility performance measures; 2. Impact of implementation of e-toll on congestion levels of the Ben Schoeman Freeway. 3. Value of using mobility measures to assess change in traffic conditions over time. A substantial improvement in traffic congestion levels are observed, although it is clear that congestion is still at significant levels and that continuing traffic growth will counter the advantages yielded by the road upgrades in due course. It is also observed that the e-tolling system initially led to a decrease in traffic volumes, but that this effect had already been phased out by mid-2014.


Objective: Heart rate variability (HRV) is used to evaluate the autonomic activity of heartbeat. This study aimed to investigate the
effects of cholinomimetic drugs cytidine diphosphate-choline (CDP-choline) and choline, on short-term HRV parameters.
Materials and Methods: Animals were randomized into three groups; control (0.9% NaCl), choline (100 mg/kg), CDP-choline (400
mg/kg). Electrocardiography recordings were obtained for 45-minutes after treatments with 15-minutes intervals. HRV analyses and
total choline level measurements in serum and heart tissues were performed.
Results: High frequency power and total power increased in treatment groups, while heart rates were decreased. Low frequency was
decreased with choline while very low frequency power decreased with CDP-choline. Choline affected most of the HRV parameters
in the first 15 minutes, while the effect of CDP-choline started within 30 minutes. Total choline levels were higher in both treatment
groups than in the control while the levels were also higher in the choline group compared to CDP-choline group.
Conclusion: This study showed that CDP-choline and choline treatments produced a rapid response to short-term HRV parameters,
while increasing tissue choline levels. Moreover, the differences in effects and onset time between the drugs on HRV might be related
to tissue choline concentration.


ABSTRACT Crisis has been a common experience in sub-Saharan Africa, at least since the 1980s with disastrous results for countless Africans. Such crises, however, can represent opportunities for entrepreneurship for those prepared to take the often-mortal risks involved, or the imposition of entrepreneurship as a strategy for getting by. In this paper, I explore the case of motorcycle taxi drivers in Kigali, Rwanda's capital. I argue first that Rwanda is not a state in crisis, exhibiting instead tight governmental control and effective social and economic regulation. To make a living in this political environment, motorcyclists are compelled to generate crisis within the systems that supposedly regulate their business. This converts governmental control into a simulacrum, at the same time as it compels motorcyclists to 'invest' life and limb in these ambiguous relationships. Thus, while current developments in Rwanda suggest that there is now no 'crisis', the way in which the country is governed demands the creation of a continuous state of crisis for many, since it is only in crisis that the opportunities to make a living can be created.


Abstract Although the failed democratic transition in Egypt following the Arab Spring is unanimously held as a poster child for the stubbornness of authoritarianism in the MENA region, its determinants remain disputed. Contributing to this debate, this article focuses on the noxious effects of past electoral authoritarianism on the transitional party system. More specifically, through quantitative text analysis, the article demonstrates that transitional parties' agency is largely the by-product of the way in which political competition was structured under the previous electoral autocracy. On the one hand, the uneven structure of opportunity upholding previous rule is central to the lack of pluralism. On the other hand, the previous regime's practice of playing opposition actors against each other through identity politics is at the root of the absence of common ground among the aforementioned parties during the transition.


This paper presents conditions on the constitutive dyads of a bianisotropic linear metamaterial that are sufficient to ensure cloaking for arbitrary shapes and arbitrary illumination. The volumetric equivalence theorem is first formulated for a bianisotropic metamaterial scatterer. By assuming that the volumetric equivalent currents do not radiate outside the cloak, and radiate the negative of the incident field in the internal cavity of the cloak, the material constituent dyads are written as a function of two vector potentials respecting simple boundary conditions. The special known cases of transformation optics are derived in terms of a particular choice of the vector potentials as a coordinate transformation of the incident field space.


We propose a novel monitor placement algorithm that reduces significantly the number of monitors required to accurately assess the QoT of all lightpaths established in an optical network, compared to other monitor placement methods.


The Mechanism of Pb removal from brass scrap by compound separation using Ca and NaF addition was investigated. Because large Ca-Pb compound particles formed by Ca addition rise to the surface of the molten brass, they can be skimmed off from the molten brass. However, fine Ca-Pb compound particles remain in the molten brass because of low buoyancy. By subsequent NaF addition, the reaction between Ca-Pb compound and NaF takes place at their contact regions, resulting in the formation of solid CaF2, liquid Pb and Na gas. Pb is mainly present at the Ca-Pb compound-CaF2 interface. CaF2 acts as a binder for aggregation of fine Ca-Pb compound particles, resulting in the formation of light and large composite compounds, which rise to the surface of the molten brass. A high Pb removal rate is achieved by skimming off.


The role of intermolecular coupling on vibrational line shapes is studied in terms of a mapping procedure relating the full spectrum with a spectrum corresponding to vanishing coupling. This spectral transform is based on a single site approximation. It exhibits an asymmetric line, exchange narrowing, and a shift of the line center depending on the average intermolecular coupling. Fluctuations of the total amount of intermolecular coupling at a reference molecule lead to line broadening. Fluctuations of the intermolecular coupling leaving the total amount of coupling at a reference molecule constant, invoke motional narrowing. The consequences of the model are compared with available data on isotopic dilution experiments.


The cellular mechanisms that allow for cardiomyocyte growth in different directions may yield important information about the development of hypertrophic and dilated cardiomyopathies, diseases which include the widening and lengthening growth of cardiomyocytes, respectively. We have previously found that genetic manipulations of the mitogen-activated protein kinase kinase 1 (MEK1) and extracellular signal-related kinase 1/2 (ERK1/2) signaling pathway cause cardiac hypertrophy and cardiomyocyte widening when the pathway is activated or dilated cardiomyopathy and cardiomyocyte lengthening when it is inhibited. The downstream effectors of the directional growth response controlled by these kinases have yet to be studied. Therefore, an unbiased phosphoproteomic screen was conducted on cardiomyocytes subjected to activation or inhibition of MEK1-ERK1/2 signaling. After validation of the screening hits with western and Phos-tag blots, Pre-B-cell leukemia homeobox interacting protein 1 (PBXIP1) emerged as an interesting target. Although it is known as a microtubule binding protein and regulator of proliferation in cancer cells, its function has never before been studied in the heart. Inhibition of MEK1-ERK1/2 increases phosphorylation of PBXIP1. However, activation of the pathway increases PBXIP1 protein expression, and as such we sought to determine the effects of PBXIP1 overexpression in the heart via adeno-associated virus 9 (AAV9) treatment. At four months of age, mice overexpressing PBXIP1 have significantly larger hearts than controls without a change in cardiac contractility. Intriguingly, histological analysis showed that cardiomyocytes highly infected with PBXIP1 AAV9 are significantly smaller in size compared to uninfected cells. Current studies are manipulating the PBXIP1 phosphorylation sites identified in the phosphoproteomic screen to determine the exact roles they may play in the cardiac growth response.


Aim at the torque tipple problem of brushless DC motor(BLDCM),based on the mathematical model of BLDCM with operating mode of 3-phase 6-state motor with wye-connected phase windings,five kinds of pulse width modulation(PWM) is proposed.The torque tipple effects caused by the five kinds of PWM were analyzed in detail and were compared.According to the formula deduction the PWM-ON can make BLDCM with smaller torque ripple.The experiments were done using TMS320F2812 DSP as control core and using rated 180W small BLDCM as the control object.Five kinds of PWM modulation waveforms were generated respectively by using DSP,and the fuzzy PI controller were used to control the motor.The waveforms of phase current were measured by the corresponding kind of PWM modulation.The experimental results show that PWM-ON modulation is ideal,and it effectively inhibits the commutation torque ripple of motor.The experimental results prove the correctness of the theoretical analysis.


The authors argue that owing to their unique nature, human beings invariably exist in the world as perceivers, which has been completely verified. In reality, when such problems are confronted with as unbalance of ecology; deterioration of environment and preservation of the variety of animals, solutions and opinions wll be suggested. However, no matter how reasonable or practical the suggested solutions may be people can hardly reach any agreement. This paper concludes that these problems mentioned above can be solved only by human beings themselves and that the solutions sould be based on their knowledge and rationality. The paper also argues that is is human perceivability that will play an leading role in solving these ecological problems.


Background: Considering drawbacks of all procedures of osteoarthritis surgery of knee, we decided to do restoknee surgery for medial compartment osteoarthritis of knee. The procedure is mainly based on the principle of very old and established technique of closed wedge osteoclasis, where we are not using any implants internally. Material and Method: In this procedure, we do closed wedge osteoclasis through cancellous bone between one cm below the articular surface through the subchondral bone and tibial tuberosity underneath the ligamentum patellae with base of wedge on lateral side above tip of fibular head and then gap is closed down by valgus stress and disruption of superior Tibiofibular syndesmosis. Then decompression of medullary canal of femur by lateral to medial side linear cutting between two cortices above the intercondylar notch crossing midline and opening out the medullary canal which reduces the intramedullary pressure. Because of osteoclasis of the posterior cortex, the position of both the fragments is maintained with long leg brace after closure. Now whole position is confirmed under IITV. Then wound is closed and long fixed brace is applied which is followed by short brace. Patient is allowed to walk with walker from next day of surgery. Thus, desired valgus is maintained. We have operated cases from 1997 to 2017, many patients from 1 year to 8 years with average follow up of 3.5 years, out of which 12 are males and 56 are females with average age of 58 years, out of which, 32 right and 36 left knees were treated. Result: considering all criteria and important points, we got 52 (76.47%) excellent and 16 (23.53%) good, while 0% poor result. Conclusion: Considering many findings and all criterias with short to long follow up, we got best result of medial compartment osteoarthritis of knee. Almost all patients are happy and even in longest 21 years followed up case is also absolutely happy with the result and doesn't require replacement surgery.


For deactivation and decommissioning (D&D) of contaminated structures in the weapons complex, remotely operated robotic systems are expected to replace human workers from hazardous radiation and difficult work environments, while improving productivity and reducing costs. Nevertheless, the major drawback of currently available remote operation technology is that teleoperation is a slow and imprecise process, mainly due to the difficulty of transferring perception and manipulation over a remote location. To this end, this work presents a semi-automatic teleoperation system that facilitates efficient and precise teleoperation. Building upon behavior based robotic architecture and a proprietary Cobotic hand controller, two types of enhanced teleoperation tele-autonomy and tele-collaboration – are implemented.

1~ 1942 Stout and Murray described a tumourtype characterized by a profuse proliferation of capillaries, between which were spindle-shaped or round cells. These tumours resembled the epithelioid areas of the glomus tumour which had been previously shown by the same authors to yield cells in tissue culture of similar appearance to the pericytes of Zimmermann (Murray and Stout, 1942). It was, therefore, suggested that the new tumour-type consisted of a proliferation of capillaries together with their surrounding pericytes, and the term haemangiopericytoma was applied. Murray's tissue culture of a single tumour (Stout, 1949) gave no support for this view, but Fisher, Kaufman and Mason (1952) have cultured tissue from a haemangiopericytoma and claim to have grown cells resembling pericytes. Over 100 haemangiopericytomas have now been collected by Stout, the sites including uterus, neck, arm, popliteal space, tongue, triceps muscle, omentum, pericardium and also the elbow of a dog. Of these cases 10 have shown signs of malignancy including invasion and metastasis. Twelve haemangiopericytomas have been described in the uterus and evidence of malignancy was noted in 3 of these (Greene and Gerbie, 1954; Pedowitz, Felmus and Grayzel, 1954, 1955). In 1955 we examined a uterine tumour of mesenchymal appearance and could come to no conclusion as to its nature. Sections from this tumour were seen by Dr. Emil Novak of Baltimore who suggested a diagnosis of haemangiopericytoma. A review of uterine tumours removed at St. Mary's Hospitals for Women and Children, Manchester over the past 10 years revealed 1 1 further tumours of similar appearance. The purpose of this paper is to draw attention to these tumours and to discuss their interpretation, since all gave rise to difficulty in histological diagnosis.


Although hearing loss is treated with hearing technology and rehabilitation, children with hearing loss still face challenges. Factors such as distance to the sound source and noise from the surroundings are the children's biggest enemies. In the "Listen Again" project, a listening- and spatial awareness training application was co-designed together with deaf and hard-of-hearing children who use cochlear implants. This paper presents quantitative and qualitative results from a two-month evaluation where 22 children were asked to play with the VR solution for two months, three times a week.

On the basis of a simple model we analyse the influence of disorder on critical temperature T_C in p-wave superconductors. The disorder is treated by means of the Coherent Potential Approximation (CPA) and we focus our attention on the effect of a van Hove singularity near Fermi energy E_F. For the appropriate values of its parameters our model reproduces the experimentally found behaviour of Sr2RuO4.


Revista Cubana de Reumatología ISSN 1817-5996 Volumen XII Número 15; 2010 A retrospective descriptive study in 25 patients with diagnostic of septic arthritis admitted in the Centro Nacional de Reumatología of the Hospital Clínico Quirúrgico 10 de Octubre was carried out from January of the 2005 until January of the 2010, with the objetive of identify the clinic and epidemiologic characteristics.

In this paper, we first review some important definitions and notions related to best proximity point theory by considering the lack of symmetry property of quasi metric. Then, we introduce a new notion of BG-multivalued contraction mappings. Then, a best proximity point result is obtained via Q-function on quasi metric. Also, we present a noteworthy illustrative example to show the effect of our results. Finally, we give an existence and uniqueness result for the solution of nonlinear integral equations via our result.


Cells release molecules through vesicles or into specific locations through exocytosis. Extracellular vesicle is divided into ectosomes and exosomes. Exosomes has been the main mechanism of discussion in recent studies and cancer research. As Exosomes with a diameter of ~30-160 nm (with an average diameter of 100 nm) carries intracellular molecules such as DNA, RNA, miRNA, proteins, and lipids. The physiological function of exosomes is not fully understood at present, it is important to understand the role of exosome in cancer. Src is highly activated in colon cancer and Src inhibition is the potential treatment strategy in colon cancer. In this study, colon cancer cells HT-29 were used to investigate the difference sizes of exosomes that response to Src inhibitor treatment. In the preliminary results, the exosome from HT-29 cultured medium were isolated and examined by transmission electron microscopy (TEM). The micrograph showed the average size of exosome is around 100 nm. When HT-29 were treated with Dasatinib (DST) the Src inhibitor, the drug resistant (DSTR) cells were grown, the secreted exosome from DSTR were collected and demonstrated the bigger size of exosome with average diameter of 130 nm. The role of the size changes of exosome in response to Dasatinib resistant will be further investigated, however, this study provides the clues that exosome detection can be applied in monitoring drug resistance.

This article observes the success of the Minnesota Sentencing Guidelines Commission by viewing the consistency of prison sentences and rate of prison population growth after implementation. I hypothesize that the sentencing guidelines allow for fairer sentences and manageable prison capacities. Prior research has shown the success of the determinate sentencing system. The research begins in 1979 with the Commission's conception. The results of research demonstrates that the Guidelines do in fact achieve consistency in sentencing and manageability in prison capacities.


and delicate field methods and a curious and wide-ranging understanding of cultural context—to document observed systems of performance and place them into meaningful and testable theories of improvisatory behavior. She invites us to see both the cultural detail and the larger crosscultural picture. In the field of ethnomusicology, she is carving out a new and attractive path, and it is one I hope many will walk.


A hierarchy of approximations is developed for the real zeros of an arbitrary complex real-power polynomial $f( {\bf X} )$, ${\bf X} \in R^n $. The approximations are obtained by studying the function $g( {\bf x} )$ defined by $g( {\bf x} ) = f( {\bf X} )$ (where $x_i = \log | {X_i } |$), called the exponomial of $f( {\bf X} )$, along rays ${\bf x}( \lambda ) = {\bf x}_0 + \lambda \hat {\bf x}$, as $\lambda \to \infty $. All unbounded real solutions of $g( {\bf x} ) = 0$ uniformly approach hypersurfaces of asymptotic rays. From the geometry of a convex polytope P, called the exponent polytope of $f( {\bf X} )$, (a generalization of the Newton polygon) one can determine completely: (1) the limiting form of $g( x )$ along every ray, (2) all the asymptotic rays of the hypersurface $g( {\bf x} ) = 0$, (3) all branches of $g( {\bf x} ) = 0$ with a given asymptotic ray, and (4) a hierarchy of asymptotic hypersurfaces giving the global structure of $g( {\bf x} ) = 0$ for large $\| x \|$. These properties of $g( ...


Smartphones are a vital technology, they improve our social interactions, provide us a great deal of information, and bring forth the means to control various emerging technologies, like the numerous IoT devices that are controlled via smartphone apps. In this context, smartphone fingerprinting from sensor characteristics is a topic of high interest not only due to privacy implications or potential use in forensics investigations but also because of various applications in device authentication. In this work we review existing approaches for smartphone fingerprinting based on internal components, focusing mostly on camera sensors, microphones, loudspeakers, and accelerometers. Other sensors, i.e., gyroscopes and magnetometers, are also accounted, but they correspond to a smaller body of works. The output of these transducers, which convert one type of energy into another, e.g., mechanical into electrical, leaks through various channels such as mobile apps and cloud services, while there is little user awareness on the privacy risks. Needless to say, miniature physical imperfections from the manufacturing process make each such transducer unique. One of the main intentions of our study is to rank these sensors according to the accuracy they provide in identifying smartphones and to give a clear overview on the amount of research that each of these components triggered so far. We review the features which can be extracted from each type of data and the classification algorithms that have been used. Last but not least, we also point out publicly available data sets which can serve for future investigations.


A fabrication method for electronic quantum Hall Fabry-Perot interferometers (FPI) is presented. Our method uses a combination of e-beam lithography and low-damage dry-etching to produce the FPIs and minimize the excitation of charged traps or deposition of impurities near the device. Optimization of the quantum point contacts (QPC) is achieved via systematically varying the etch depth and monitoring the device resistance between segmented etching sessions. The etching is stopped when a desired value of resistance is obtained. Finer control of interference trajectories is obtained by the gate metallized inside the etched area by e-beam evaporation. Our approach allows for a control of the delicate potential bending near the quantum well by tuning the confining potential of the quantum point contacts.

The return to equilibrium of supersaturated solutions is made in two consecutive steps. First there ie precipitation of holes, formation of dislocation loops, and resorption of the loops. The second stage is tbe germination and growth of silicon panticles. It does not appear that the germination is produced during the stage where the holes are in supersaturation in the lattice following annealing. (tr-anth)


In this paper we study a Ricci-Hessian type manifold $(\Bbb{M},g,\varphi,f,\lambda)$ which is closely related to the construction of almost Ricci soliton realized as a warped product. We classify certain classes of the Ricci-Hessian type manifolds and derive some implications for almost Ricci solitons and generalized $m$--quasi-Einstein manifolds. We consider two complementary cases: $\nabla f$ and $\nabla\varphi$ are linearly independent in $C^\infty(\Bbb{M})$--module $\mathfrak{X}(\Bbb{M})$; and $\nabla f=h\nabla\varphi$ for a smooth function $h$ on $\Bbb{M}$. In the first case we show that the vector field $\nabla\lambda$ belongs to the $C^\infty(\Bbb{M})$--module generated by $\nabla f$ and $\nabla\varphi$, while in the second case, under additional hypothesis, the manifold is, around any regular point of $f$, locally isometric to a warped product.


It is well established that parenchymatouis organs undergo marked rearrangement of architecture in chronic productive inflammations, and that knowledge of this altered construction is essential for an understanding and explanation of pathological function. The kidney, on account of an intricate vasculature and complicated parenchyma, is peculiarly liable to involved structural alterations; if renal function is complex and difficult to understand under physiological conditions, the pathological organ offers in that respect many additional obstacles for investigation and explanation. Of the various forms of Bright's disease, the Productive Indurative Nephritis, commonly spoken of as Contracted Kidney, shows the greatest and most perplexing changes, particularly in its arterial distribution. The following experiments and studies have consequently been directed largely to the study of this form of nephritis. The method has already been described in detail in a previous article,' i.e., injection of the blood vessels with a barium-sulphate suspension in gelatine and then stereoscopically skiagraphing the kidneys. By this means it was shown that a clear, plastic, and exact representation of the vasculature can be obtained. By a number of observations, presented in the previous paper, we have obtained what may be regarded as the


The variations in the lake water storage in the Tianshan region are an important indicator of climate change and play a key role in understanding the hydrological mass balance. Based on altimetry and satellite gravity, we investigated the spatiotemporal characteristics of the lake water storage changes during 2002–2022, and examined the contributions and proportions of all of the hydrological components to the mass balance. The results indicate that the total water storage of the lake complex showed an increasing rate (0.73±0.10 Gt/a). We found two abrupt wet periods in 2010 and 2016 (the regional total mass increased by 65.73 Gt and 67.35 Gt, respectively), which were reflected not only by the lake water storage but also by the soil moisture, snow water, and even GNSS displacement fields. Compared with their contributions to the mass (22% and 14%), the variations in lake area were remarkably slight (0.01% and 0.014%). Among the hydrological components, the soil moisture played a dominant role, and the contribution of the snow accumulation changes was also considerable. The mass anomalies were closely related to the precipitation caused by the increase of water vapor content, which was further associated with the occurrence of ENSO events (r=0.55, p<0.01). The results revealed that the long-term trend of the GNSS vertical displacements exhibited a better stability after the load correction was applied, which could reflect the long-term ground deformation more accurately. This study contributes to our understanding of the complex hydrological and tectonic processes in the Tianshan region.

In 1962 spectrographic observations conducted at Abastumani revealed increased intensity in the Hα hydrogen line in the twilight glow of the sky. Observations carried out in the 1962-1968 helped to establish the so called morning-evening effect. Morning intensities proved to be higher than the evening ones. The variations in Hα intensities were ascribed to the heights of the luminous layers of the Earth's atmosphere. Information has been obtained on the quantity of hydrogen at heights of 180-300 kms. Observations made in different directions revealed increased intensity in the hydrogen line towards the North as compared to the East and the West. Changes in Hα intensities connected with solar activity levels were fixed. In 1962 maximum intensity was registered; in 1964, 1965 and 1966 the intensity was at minimum level;beginning with 1967 intensity started to rise again.

An attempt was made to explain the result not only on the basis of dissipation of hydrogen from the atmosphere, but also on the basis of the accretion in tho atmosphere.


ABSTRACT The authors explored how classroom gender composition moderated the relationship between having classmates with emotional and behavioral disorders (EBD) and peers' academic achievement in both kindergarten and Grade 1 classrooms. Given the behavioral and social-cognitive styles of girls, it was hypothesized that classrooms with a higher percentage of girls would moderate (or reduce) the academic consequences associated with exposure to children with EBD. To address this hypothesis, this study relied on applying quasi-experimental methods to a nationally representative data set (i.e., Early Childhood Longitudinal Study–Kindergarten Class) of U.S. elementary school students. Consistent with prior research, the findings revealed that exposure to a classmate with EBD resulted in lower reading and mathematics scores for classmates. However, classrooms with a higher percentage of girls were found to protect other students' academic achievement when in the presence of an EBD classmate. The findings presented in this study can be used to challenge educators and policy makers to develop support classroom environments for all students. Educational implications are discussed.

Aiming at the multivariable coupling characteristics and the complexity of its control inside the concrete curing box, this paper firstly analyzes the coupling relationship between temperature and humidity in the curing box, and uses the decoupling strategy of the feedforward compensation algorithm. The simulation results show that the decoupling effect is good. Then, based on the principle of the self-adjusting function on the transient performance of the system, a self-adjusting factor fuzzy controller is designed, which combines the decoupling method and the self-adjusting function to improve the control effect of the coupling variable of temperature and humidity inside the concrete curing box.


There are many layout problems in various kinds of manufacturing systems. Commonly, these layout problems are associated with the determination of the place where facilities such as machines and departments are in the factory. In fact, manufacturers are imposed high costs because of high levels of material handling. Therefore, minimizing the material handling cost is the main purpose of facilities layout problems. The aim of this study is making a comparison between two layout improvement methods, CRAFT and Graph Based for improving the layout of a manufacturing system. It shows that Graph Based method has had a better result in comparison with CRAFT based on its efficiency.

Familial Mediterranean fever (FMF) is an autosomal recessive inherited disease affecting mainly certain ethnic groups of Mediterranean origin and characterized by febrile aseptic polyserosites. FMF as an ethnic disorder is widespread in Armenia and it is more often diagnosed in children recently. Genetic testing of FMF is efficient for diagnosis of the disease and allows to diagnose atypical cases. MEditerranean FeVer (MEFV) gene frequency and the prevalence of heterozygous carriers of one of MEFV mutation in Armenian population are rather high: 0.21 (1:5). The total number of FMF children in the National Pediatric Centre for FMF (NPC for FMF) increased from 500 to 1900 since 2003 and the annual number of newly diagnosed pediatric cases during the last 5 years reached 300-350. Different abdominal or digestive system manifestations are observed in FMF. They make the differential diagnosis difficult and may result in late diagnosis of FMF and complicated course. The aim is to investigate clinical and genetic characteristics of the abdominal and digestive system manifestations in Armenian children with FMF. During 1997-2008 we observed 715 patients with FMF at the NPC for FMF. There were 438 boys and 277 girls aged from 3 months to 17 years (mean age: 8.64±0.17). The diagnosis of FMF and severity of disease were confirmed according to the generally recognized criteria [Livneh A. et al., 1997; Livneh A., Langevitz P., 2000] and MEFV mutation analysis. Besides FMF abdominal febrile attacks (92.4%) associated with homozygotes for M694V and compoundheterozygotes for three main mutations M694V, M680I, V726A (p<0.05), a number of other abdominal and digestive system manifestations of FMF have been observed: adhesive intestinal obstruction (AIO) (3.2%), hepatomegaly (17.7%), splenomegaly (9.9%), concominant ulcerative colitis (UC) (0.4%), as well as protracted febrile myalgia (PFM) (2.7%), Henoch-Shonlein purpura (HSP) (1.5%), Behcet disease (BD) (0.1%). Some of these diseases and symptoms were more frequent than expected. The frequency of AIO, FMF-associated vascuitides, UC was associated with M694V mutation, mainly, homozygous genotype, high disease severity, early onset and delayed diagnosis. Patients with UC had atypical onset of disease during the first year of life: recurrent febrile colics, diarrhea and/or abacterial haemocolitis. Later myalgia, arthritis, polyserosites and resistance to treatment of UC were observed. Thus, FMF patients with severe course of disease and M694V mutation, especially with homozygous genotype were at a high risk for abdominal and digestive system manifestations. Some of them (AIO, UC, splenomegaly) might be considered as possible markers of severe course, even in the absence of typical FMF symptoms. They might be the early, first and only manifestations of FMF. Considering the high prevalence of FMF in Armenia, we believe that the genetic screening for FMF might be indicated for children with some abdominal and gastrointestinal manifestations: adhesive (mechanical) intestinal obstruction, FMF associated vasculitis (HSP, PFM, BD), inflammatory bowel disease (UC, Crohn's disease), splenomegaly of an unknown origin, recurrent abdominal pains, especially in case of early disease onset, atypical presentations and resistance to treatment. Early diagnosis and treatment of FMF digestive system manifestations improve the course of disease and prevent amyloidosis.

Using hindcast and forecastdata from the National Centers for Environmental Prediction (NCEP) Climate Forecast System version 2 (CFSv2)for the period 1982-2017, we comprehensively assess the predictability of the climatology, interannual variability, and dominant modes of the wintertime 500 hPa geopotential height over Ural-Siberia (40-80°Nand 30-100°E). Although the climatic mean 500 hPa heightover Ural-Siberia simulated by NCEP CFSv2has a negative bias, especially over the eastern part of the region, NCEP CFSv2 well predicts the spatial distribution of the two major modes(EOF1 and EOF2) over this region 2 months in advance.The forecasting skill of the principal component (PC) of the two major modes,PC1 (PC2), is highest1 (0) month in advance, where the linear correlation coefficient between the predicted and observed time series reaches +0.36 (+0.67), exceeding the 95% confidence level. Conversely, the forecasting skill of PC1 (PC2) is very low 0 (1) month in advance. The main reason for the poorer(better) prediction of PC1 0 (1) month in advance is associated with a less (more) accurate response of the Eurasian teleconnection to SST anomalies over the southwestern Atlantic. For PC2, the better (poorer) prediction of PC2 0 (1) month in advance may be due to more (less) accurate responses of the stratospheric polar vortex and the Scandinavian teleconnection to the dipole SST anomalies over the North Pacific. These results are useful for evaluating the predictability of the East Asian winter climate.


Advances in the development of low powered sensors has meant they can now provide solutions to Internet of Things (IoT) networks that suffer from restricted power supply and a lack of resource facilities. In this paper, a hybrid time division multiple access (TDMA)-carrier sense multiple access with a collision avoidance mechanism (CSMA/CA) medium access control (MAC) protocol has been proposed that efficiently utilizes the energy of the nodes and dynamically adapts the sleep/wake-up periods according to the variance in the network loads. This hybrid protocol first schedules the TDMA time slots ( ${\mathrm {TDMA}}_{\text {slots}} $ ), and then allocates each slot to a group of devices that compete for the medium using the CSMA/CA. This case is different from the traditional CSMA/CA-TDMA hybrid protocol, in which all the devices compete to access the channel, following which, each successful device is allocated an individual time slot. At the commencement of each superframe, the base station broadcasts a scheduler table, which includes network grouping information that is used by the IoT devices to categorize themselves into wake-up and sleep groups. To reduce the number of collisions or channel access failures, this information permits only one group to compete for each ${\mathrm {TDMA}}_{\text {slot}} $ . A 3-D Markov model is used to develop a per user stochastic behavior for the proposed hybrid MAC protocol-based adaptable sleep mode. The simulation results demonstrate the effectiveness of the proposed protocol, which improves the network throughput and enhances energy conservation by 40%–60% more than the IEEE 802.15.4-based MAC protocol.


Professor Gieselman's article provides a useful content t analysis of the articles published in The Journal of ___ Business Communication and elsewhere. Unfortunately, there are several limitations that restrict the article's utility. This reply will focus on four such limitations. 1. The section on &dquo;Stages of Research Growth&dquo; was unsubstantiated. Although Gieselman studied the ten-year period of 1969-1979, he describes four phases dating from pre-1940 to the present. As there is no evidence that his description emerged out of a systematic analysis of the literature on business communication, we are provided with an undocumented guess (albeit an educated one) about what one might find should he or she take the time to investigate. My own educated but unsystematic guess is that the phases in business communication research are not linear but circular or


Przytycki and Sokolov proved that a three-manifold admits a semi-free action of the finite cyclic group of order p with a circle as the set of fixed points if and only if M is obtained from the three-sphere by surgery along a strongly p-periodic link L. Moreover, if the quotient three-manifold is an integral homology sphere, then we may assume that L is orbitally separated. This paper studies the behavior of the coefficients of the Conway polynomial of such a link. Namely, we prove that if L is a strongly p-periodic orbitally separated link and p is an odd prime, then the coefficient a 2i (L) is congruent to zero modulo p for all i such that 2i < p - 1.


Elastic peak electron spectroscopy (EPES) was employed to measure the inelastic mean free path (IMFP) for energies between 500 and 1600 eV for five insulating organic compounds: Kapton, polyethylene (PE), poly(methyl methacrylate) (PMMA), polystyrene (PS) and polytetrafluoroethylene (PTFE). A Ni and a Si sample were used as reference materials to avoid measurement of the elastic reflection coefficient in absolute units. Correction of experimental elastic peak intensities for surface excitations was performed which turned out to be essential. The results are compared with recent evaluations of optical constants to yield the IMFP in the literature giving satisfactory agreement, with deviations generally below 20%. Investigation of the kinematics in an electron reflection experiment shows that the dispersion coefficient used in REELS data analysis cannot be identified with the true plasmon dispersion.


China is in the industrialization and urbanization process, a critical period, and energy consump- tion and carbon emissions resulting from economic development have received widespread attention at home and abroad, which makes the issue of climate change in China at the forefront of international debate. Whe- ther China's development model can be developed to avoid duplication and step on to path of stable, low- carbon, sustainable development is one of the key issues of world's response to climate change. This paper firstly overviews the current situation on carbon emissions, and analyzes policies and measures of greenhouse gas reduction and emission of developed countries. Some countermeasures for greenhouse gas reduction in China are put forward based on the actual situation of energy utilization structure of China. With the perfec- tion of various measures, China will surely make achievements in carbon dioxide reduction.

A method is provided for reconstructing data generated on a digitizer tablet based on the dynamics of the data generation. The digitizer tablet samples the position of the writing pen, continuously transmitting data to a computer in the form of x and y coordinates plus an indicator of whether or not the pen is touching the surface of the tablet. After preprocessing, the data is reconstructed based on the dynamics of the data's creation. The values of the dynamic reconstruction are created by accumulating increments that are some function of the original data. To enhance the dynamics a nonlinear function is required.


The solid state polymerization of the disubstituted diacetylene 1,6-bis(2,4-dinitrophenoxy)-2,4-hexadiyne by thermal annealing at 130°C to yield high quality polymer single crystals is reported. This compound is unique in that it polymerizes by thermal annealing but not under ordinary x-ray conditions, thus allowing determination of the crystal structures of both the monomer and polymer by x-ray diffraction. The conditions for solid state polymerization and the structural changes during polymerization were investigated. In addition, the kinetics of polymerization were studied by differential scanning calorimetry. An induction period with activation energy EA(slow) = 139,7 ± 3 kJ/mol (33,4 ± 0,7 kcal/mol) is followed by a rapid polymerization regime with activation energy EA(fast) = 132,2 ± 6 kJ/mol (31,6 ± 1,5 kcal/mol) during which first order kinetics are obeyed. The total heat of polymerization is − ΔHp = 134,7 ± 6 kJ/mol (32,2 ± 1,5 kcal/mol). After polymerization, a disordering phase change takes place with continued isothermal annealing which becomes clearly evident at isothermal annealing temperatures higher than 130°C.


We study methods of distinguishing the new physics operators which
provide a good fit to the excess measured value of $R_{D^*}$. Among the
angular observables, we find that the $D^*$ polarization fraction
$f_L(q^2)$ is a good discriminant of scalar and tensor new physics operators.
The change in $\langle f_L (q^2) \rangle$, induced by scalar and tensor
operators, is about three times larger than the expected uncertainty in
the upcoming Belle measurement.


Adsorption behavior of Cu(Ⅱ) ions from wastewater of new chemically modified material MCM-41(mobil composition of matters) was studied.Two new kinds of material(Al-Ti-MCM-41 and Ti-Al-MCM-41) have been chemically modified with Al,Ti ions.The sample of Al-Ti-MCM-41(1∶1) was characterized by nitrogen adsorption and desorption isotherms data.The adsorption of Cu2+ on the modified materials was investigated.The effects of adsorbent dosage,temperature and initial concentration on the adsorption capacity were investigated in detail.The results showed that: The pore volume of Al-Ti-MCM-41was 0.04 cm3/g,the BJH (Barret-Joyner-Halenda) average diameter was 17.02 nm.Cu2+ was adsorbed quantitatively to the Al-Ti-MCM-41,and the absorption ratio was 99.95%.The adsorption capacity and removal percentages of Cu2+ decreased with the adsorbent dosage increased but increased with the initial concentration increased.A higher temperature was in favor of adsorption.


Moment-closure approximations are an important tool in the analysis of the dynamics on both static and adaptive network s. Here, we provide a broad survey over di fferent approximation schemes by applying each of them to the a daptive voter model. While already the simplest schemes provide reasonable qualitati ve results, even very complex and sophisticated approximat ions fail to capture the dynamics quantitatively. We then perform a deta iled nalysis that identifies the emergence of specific corre lations as the reason for the failure of established approaches, before pr esenting a simple approximation scheme that works best in th e parameter range where all other approaches fail. By combining a focuse d review of published results with new analysis and illustra tions, we seek to build up an intuition regarding the situations when e xisting approaches work, when they fail, and how new approac hes an be tailored to specific problems.


Dairy enterprises have to cope with intense market pressure and survival pressure. In such complex and competitive market environment, it is of great realistic significance for studying the influence of strategy selection of dairy enterprises on their performance. Through selecting 115 dairy enterprises, empirical analysis was made, and multiple linear regression model and structural equation model were established with the aid of SPSS and Amos software. Comparative analysis was carried out for performance of different strategy selection. Results indicate that dairy enterprises selecting vertical strategies obtain the best performance, followed by horizontal strategy, and the worst is multiple strategy, and the strategy selection exerts positive and direct influence on performance of dairy enterprises.


ACOS5 encodes and enzyme required for sporopdlen monomer biosynthesis and is one of the crucial genes for normal male fertility in Arabidopsis.Blast analysis exhibited that several proteins from distinct plant species showed high homologoue to ACOS5 and there were 64% identities at amino acid level between ACOS5 and its rice homologue(OsACOS).The phylogenetic analysis further indicated their tight relationship in evolution.RT-PCR analysis of OsACOS in several stages floret treated by low and high temperature respectively was performed using the primers based on the rice homologous sequence.The result demonstrated that the expression level of OsACOS was low at the microsporocyte formation stage,whereas it was increased dramatically from the meiosis stage.During these two early stages,significantly higher level of OsACOS mRNA abundance was induced at the lower temperature(20 ℃) compared with that at the higher temperature.However,this trend was reversed at the formation of microspores stage.Therefore,the ambient temperature significantly imposes the transcription expression of OsACOS and the effect was developmental stage-dependent.It suggested that OsACOS might be involved in the regulatory pathway through which the ambient temperature controls the male fertility of rice.


Self-Regulated Learning (SRL) has been a growing topic since 1983 in the Scopus database. The importance of SRL has been known through several studies because it is proven to be able to improve student learning outcomes, both at school and in life. The purpose of this study is to determine the trend of topics in the field, through bibliometric analysis with the help of the VOSViewer application. Findings reveal that there is still little discussion on the topic of SLR in mathematics learning. The journal that can be used as a reference is the International Journal of Science and Mathematics Education, which the latest topics related to Learning Systems and Education. Suggestions for further research are to make technology-based learning models using the latest theories and research results and evaluate the results achieved for improving students' learning outcomes in mathematics and in life.
