particularly in the areas of feature detection and feature extraction. Edges are significant local changes of intensity in an image. Edges typically occur on the boundary between two different regions in an image. The problem is that the general edge detectors behave very poorly. In this paper, a Multiscale Beamlet Transform is employed for edge detection. Beamlet Transform is used to extract edges, ridges and curvilinear objects in digital images. These transforms are beyond the wavelet transform in the sense that they retain not only the location and scale, but also directional information, which is essential in the image and is not retained in the wavelet analysis. This paper presents efficient hardware architecture for Beamlet Transform Edge detection algorithm using Xilinx System Generator (XSG). This architecture combines MATLAB, Simulink and XSG. The hardware design is implemented by using Xilinx System Generator, whereas the software part is developed by using Matlab. The parallel computing power of the field programmable gate array (FPGA) is extremely useful in the modern world of demanding
applications like digital image processing and video editing. However, configuring this power can be difficult. So Matlab has created a package called System Generator which allows Xilinx chips to be programmed with the common MatLab programming environment Simulink. Beamlet Transform Edge Detection algorithm achieves a higher SNR, Position accuracy and provides
more complete edge than wavelet transform.

A 56-year-old woman presented with a left axillary mass that was incidentally detected during an ultrasound examination 3 months ago. She had undergone a bilateral prophylactic mastectomy and immediate reconstruction with breast silicone implants, due to an extensive lobular carcinoma in situ, 5 years ago. On physical examination, a non-tender, hard, and relatively movable mass measuring approximately 3 cm was palpated in the left axilla. The ultrasound revealed at least four enlarged axillary level I nodes demonstrating a ̈snowstorm ̈ appearance (Figure 1). A subsequent MRI scan revealed a rupture of the left breast implant with the presence of free extracapsular silicone gel and extensive ipsilateral axillary lymphadenopathy (Figure 2,3). Based on the ultrasound and MRI findings, the possibility of silicone lymphadenopathy was considered. However, as malignant lymphadenopathy could not be definitively ruled out and the ruptured implant had to be replaced a surgical excision was performed. At surgery, six macroscopically involved axillary lymph nodes were removed and the ruptured implant was replaced by plastic surgeons. On gross examination, the lymph nodes were whitish and elastic, measuring from 1.1 to 2.6 cm. On cut surface, they had a microcystic appearance with the presence of clear colloid material. The histopathological findings were suggestive of silicone lymphadenopathy (Figure 4). The patient is well with no signs of recurrence 26 months after surgery. Axillary silicone lymphadenopathy (ASL) is the deposition of silicone in one or more axillary lymph nodes following the leak or rupture of a breast silicone implant. Silicone particles migrate through the lymphatics to the axillary nodes where they invoke a nonspecific


Objective To study the effects of Hepatitis B virus(HBV) gene mutations on disease development,severity and anti-virus therapy in chronic hepatitis B patients.Methods HBV gene mutational sites were detected by gene chip in the hepatitis B patients selected by expectation.Results The patients whose HBeAg did not occur seroconversion, or presented HBeAg (-) / anti-HBe (+) seroconversion but HBV-DNA still remained positive after α-interferon therapy for 24 weeks were associated with mutations of nt1896,nt1814,nt1762 and nt1764.The patients whose HBV-DNA levels decreased or were undetectable,but rebounded later after anti-virus therapy by lamivudine were associated with mutations of aa528 and/or aa552 (i.e.YMDD mutation) that resulted in lamivudine-resistance.YMDD mutation was prone to occur after 52 weeks by lamivudine therapy in some chronic hepatitis B patients (26.4%).The site of nt1896 mutation was common in most chronic hepatitis B patients (68.5%).Chronic severe hepatitis,cirrhosis,and primary hepatic carcinoma were related to the mutations of nt1896,nt1762 and nt1764.Conclusions HBV gene mutations could aggravate patient's condition and affect anti-virus therapeutic efficacy.The regular detection of HBV gene mutative sites will benefit for identification of disease prognosis and adjustment of therapeutic strategy. \[


Stress analyses were performed for the window of the Purdue Mach-6 quiet-flow Ludwieg tube. Stress concentrations on the windows were relieved by modifying the geometrical configuration as well as by changing the gasket material. A modified gapped geometry on the surface between the gasket and frame was proposed, based on the results from the elastic finite-element analyses. The proper gasket material was chosen to lessen stress concentrations, based on results from elasticperfect-plastic analyses. The peak stress (compressive stress) on the window was reduced from 50400 psi in the original design to 5310 psi in the new design, when 300 psi of internal pressure is applied. The peak stress was 2340 psi when 150 psi of internal pressure is applied, and the safety factor was 4.7, considering the tensile strength of 11000 psi for plexiglas. A threedimensional finite element analysis was performed to verify the validity of the twodimensional analyses. Initial operations are also described.

Comparing with the results of analytical solution,the relative errors between them are very little. Therefore,combination of analytical solution and numerical calculation not only enhances to understand electric potential distribution but also produces effect of validating each other in the process of calculation and analysis of electromagnetic fields.


The difficulty in determining trace-level organoseleno metabolites and the lack of commercially available standards have been major barriers to a molecular-level understanding of Se biogeochemistry, ecotoxicology and nutrition, particularly in aquatic ecosystems. To overcome the problem, three important precursors of volatile alkyl selenides were synthesized, including dimethylselenonium propionate (DMSeP), which has only been postulated to exist in nature. A combination of 2-D multinuclear NMR, electrospray MS and GC–MS methods was employed to identify DMSeP, methylselenomethionine and methylselenocysteine in synthetic preparations without extensive clean-up. An alkaline hydroelimination test coupled with GC–MS analysis for the release pattern of dimethyl selenide (DMSe) and dimethyl diselenide (DMDSe) was developed for a diagnostic determination of the three products. The DMSe release pattern of DMSeP confirmed the presence of a DMSeP-like compound in the biomass of 100 mg l–1 Se-treated Chlorella investigated previously. Silylation–GC–MS was tested for the determination of selenomethionine, selenocysteine and methylselenocysteine in a standard mixture with a detection limit of better than 1 pmol per 0.5 µl injection volume for selenomethionine. This method was applied to the analysis of the acid digest of the proteinaceous fraction of the Chlorella culture. Selenomethionine was found to contain >70% of the protein-bound Se, although this constituted only a minor fraction of the total Se in the Chlorella biomass. These findings revealed the metabolic relationship between Se volatilization and selenomethionine incorporation into proteins. This knowledge is critical to advancement in Se biogeochemistry, ecotoxicology and the development of in situ bioremediation schemes.

In general, very limited information is available on the adsorption of antibiotics by granular ferric hydroxide (GFH) in an aqueous solution. In order to gain an understanding of the adsorption process of cefixime by GFH, this study was conducted in a controlled batch system and using central composite design by response surface methodology (RSM). The effects of pH, initial Cefixime concentration, adsorbent dose and contact time on the adsorption rates of cefixime were investigated. The results of optimization of the variables derived in the initial pH = 6, cefixime concentration were 8 mg L, adsorbent dosage = 1 g L and contact time = 50 min, and maximum removal efficiency of 99.63%. According to RSM, this study follows the Quadratic model (R = 0.970). Considering the good quality, economic and feasibility aspects, adsorption of CFX with GFH is recommended as a successful method of CFX removal from various aqueous solutions.

Abstract Three rates of the post-emergent herbicide paraquat, 0.7, 0.35 and 0.175 kga.i./ha in 560 //ha were applied to weeds between rows of rubber seedlings. At each rate of paraquat, spray drift caused some defoliation of the seedlings but this was considerably higher at 0.7 kg a.i./ha than at the two lower rates. Death of individual seedlings was negligible at 0.175 kg a.i./ha. Weed control increased with dosage, but 0.175 kg a.i./ha gave acceptable control, which was also completely safe to budgrafts. At this rate, bud development was not affected and growth was comparable to the hand-weeded control.

The ongoing pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), necessitates strategies to identify prophylactic and therapeutic drug candidates for rapid clinical deployment. A high-throughput, high-content imaging assay of human HeLa cells expressing the SARS-CoV-2 receptor ACE2 was used to screen ReFRAME, a best-in-class drug repurposing library. From nearly 12,000 compounds, we identified 66 compounds capable of selectively inhibiting SARS-CoV-2 replication in human cells. Twenty-four of these drugs show additive activity in combination with the RNA-dependent RNA polymerase inhibitor remdesivir and may afford increased in vivo efficacy. We also identified synergistic interaction of the nucleoside analog riboprine and a folate antagonist 10-deazaaminopterin with remdesivir. Overall, seven clinically approved drugs (halofantrine, amiodarone, nelfinavir, simeprevir, manidipine, ozanimod, osimertinib) and 19 compounds in other stages of development may have the potential to be repurposed as SARS-CoV-2 oral therapeutics based on their potency, pharmacokinetic and human safety profiles.

Objective: To observe the prevention and therapeutic effects of electroacupuncture (EA) in the treatment of peripheral nervous lesion in experimental diabetes mellitus (DM) rats. Methods:42 Wistar rats were randomized into normal group (n=13), EA group (n=15) and model group (n=14). DM model was established by intraperitoneal injection of 2% Streptozotocin (STZ). Bilateral "Shenshu"(BL 23) and "Huantiao"(GB 30) were punctured with filiform needles and stimulated electrically for 20 min, once every other day (4 weeks altogether). The conduction velocity of the sciatic nerve was determined with electrophysiological method under anesthesia (20% urethane 5 mL/kg) and microstructural changes of the nerve fibers were observed under transmission electron microscope. Results: In model group, the conduction velocity of the bilateral sciatic nerves decreased significantly and the latency of the evoked action potential prolonged compared with those of normal group (P 0.001). In comparison with model group, the conduction velocity of the bilateral sciatic nerve increased significantly (P0.05) and the latency shortened markedly (P0.05). In comparison with model group, both the demyelination ratio of the myelinated nerve fibers and the swelling state (thickness) of the endothelial cells of the micro-vessels in EA group reduced significantly (P0.001). Conclusion: EA is of favorable effect in improving peripheral nervous lesion in MD rats.

Selected configuration interaction (CI) calculations and second order perturbation theory are combined to systematically approach the full‐CI limit. The resulting algorithm has negligible requirement for memory or disk space, being limited only by available cpu time. Comparison is made to existing full‐CI benchmarks (DZ and DZP water, the oxygen atom and its anion, ammonia and the magnesium atom). In all cases the full‐CI result is recovered to better than 0.1 kcal/mol.


Mice homozygous for a defect in the PTCD2 (pentatricopeptide repeat domain protein 2) gene were generated in order to study the role of this protein in mitochondrial RNA metabolism. These mice displayed specific but variable reduction of ubiquinol-cytochrome c reductase complex activity in mitochondria of heart, liver and skeletal muscle due to a decrease in the expression of mitochondrial DNA-encoded cytochrome b, the catalytic core of the complex. This reduction in mitochondrial function has a profound effect on the myocardium, with replacement of ventricular cardiomyocytes by fibro-fatty tissue. Northern blotting showed a reduction in the mRNA for the mitochondrial DNA encoded proteins cytochrome b (cytb) and ND5 (NADH dehydrogenase subunit 5) and an elevation in a combined pre-processed ND5-CYTB transcript. This suggests that the PTCD2 protein is involved in processing RNA transcripts involving cytochrome b derived from mitochondrial DNA. This defines the site for PTCD2 action in mammalian mitochondria and suggests a possible role for dysfunction of this protein in the aetiology of heart failure.


Transient stability is treated as one of the important constraints for calculating available transfer capability (ATC), especially in Japan. Therefore, to improve the time required for ATC calculation, development of high‐speed transient stability analysis is required. For this analysis, a screening method that can recognize the serious case of fault will be greatly effective to solve the problem. Many screening methods on the first swing instability are proposed these days. However, a method based on multiswing instability has not been developed and its characteristic is not understood clearly. In this paper, the relationship between the nonlinear limit cycle and the energy function of a power system is examined using the Hopf bifurcation theory. A calculation method, which gives the critical transfer capability considering multiswing instability, is proposed. © 2006 Institute of Electrical Engineers of Japan.

Calculations of the stability of the buoyancy-induced flow of cold water, adjacent to a vertical surface, have been carried out. The disturbance equations, for an isothermal boundary condition, have been formulated with a new density relation for pure and saline water, of very high accuracy. Buoyancy terms in the base flow and disturbance equations, thereby, accurately express the buoyancy forces in water at low temperatures. Stability results are presented for a Prandtl number of 12.6 for a variety of ambient and surface temperature conditions. The anomalous cold water density behavior was found to produce important differences in stability from the Boussinesq solutions. The Boussinesq approximation consistently overpredicts the buoyancy force in upflow circumstances. The resulting neutral stability prediction lies upstream of the accurate ones. For temperature conditions which result in downflow, the predictions lie downstream of the accurate values. The effects may be very large.


Abstract Palladium-catalyzed oxidative cyclization of terminal-olefin-tethered phenols was achieved in good yields (61–90% yields). The reaction was optimized and White catalyst {[1,2-bis-(phenylsulfinyl)ethane]palladium(II)acetate} provided the best yield in the presence of benzoquinone as an oxidant. The reaction tolerated both electron-donating and electron-withdrawing substituents on the substrates, and the structure of the tetracyclic flavonoids was confirmed using single-crystal X-ray analysis. The study represents the first example of successful allylic C–H activation/ C–O bond formation using terminal-olefin-tethered phenols.


In the mid 1950s, a small number of scientists first postulated the role of oxidative stress and oxygenderived free radicals in the pathophysiological mechanisms underlying various types of human disease, including ischemic disease. However, before 1975, because of the technical difficulty of measuring the amounts of free radicals and quantitating oxidative damage, it was very difficult to prove that free radicals could contribute to cell pathology. For that reason, the importance of oxidative stress in biological systems was not definitely recognized until the early 1980s, when measurement of short-lived oxygen-derived reactive species and their detection was made possible by the advent of sophisticated techniques such as electron paramagnetic resonance (EPR) spectroscopy or fluorescent probes. These enabled both the study of free radical biochemistry and the acquisition of useful information about the nature and consequences of free-radical-induced protein and lipid oxidation, both in vitro and in vivo.

The purpose of this article is to approximately compute the eigenvalues of the symmetric Dirichlet Laplacian within an interval $(0,\Lambda)$. A domain decomposition Ritz method, PU-CPI, is proposed. This method can be used in distributed computing environments where communication is expensive, e.g., in clusters running on cloud computing services or networked workstations. The Ritz space of PU-CPI is obtained from local subspaces consistent with a decomposition of the domain into subdomains. These local subspaces are constructed independently of each other using only data related to the corresponding subdomain. Relative eigenvalue error is analysed. Numerical examples on a cluster of workstations validate the error analysis and the performance of the method.


This article investigates the gendered expressions of emotions in regard to experienced material hardship and professional aspirations in the memoirs of a Lutheran clergyman in 18th-century Finland, Johan Frosterus (1720–1809). In his narrative, Frosterus links the material hardship of his parents during the Great Northern War with the material difficulties he himself experienced during his young adulthood. In retrospect, he underlines the lack of books and appropriate clothing that stood in the way of his aspirations to establish himself socially and professionally as a clergyman, eligible both for a clerical position and marriage. Patronage and the emotional and material help through family members, especially Frosterus' mother, are discussed as central parts of this process. The narrative describes both the emotions linked to the lack of these objects and the social relationships surrounding these status symbols, offering valuable insights into how materiality and emotions interact with constructions of masculinity – and in particular, clerical masculinity – in early modern life writing.

"What is qualitative research?" "Is it a valid research methodology?" A few years ago I submitted a manuscript of my dissertation research that utilized a qualitative research method for possible publication. These were the comments I received from one of the reviewers. In our science-based world as medical laboratory professionals, we focus on the numbers. What are the standard deviation, the coefficient of variation, and the p value? What does a ROC curve or an ANOVA comparison indicate? We are accustomed to analyzing numbers, Levey-Jennings control charts, and graphs. However, even in our world of numbers some information is best collected and analyzed utilizing a qualitative research method. Before we delve into the qualitative research methods, let's review the basics of quantitative research. Quantitative research allows data to be collected that focuses on precise and objective measurements that use numerical and statistical analysis to support or refute a hypothesis. The results of quantitative research are often generalizable, predictable, and provide a causal explanation. The researcher role is considered detached and impartial. Data collection methods consist of random sampling of people that should statistically represent a population, a controlled experiment that can be reproduced in which variables can be adjusted to examine the effect, or documentation of observations as with a case study. Statistical analysis of the data may include calculation of a mean, standard deviation and a t-test. Analysis of the numbers is used to objectify the data. This is the research method with which most of us are probably…


To obtain the basic data of congenital uronephropathy pattern and the affecting factors in children, we conducted a cross-sectional study at the Department of Child Health Cipto Mangunkusumo (CM) Hospital Jakarta from 1995 to 1999 and 9 teaching hospitals throughout Indonesia. During the study period 134 patients were obtained, 116 patients from the CM Hospital and 18 patients from other teaching hospitals. Most patients (48.8%) were below 1 year of age; male were affected more than female (2.4:1). The disorder was classified into two groups, i.e., congenital nephropathy and uropathy. There were 10 children with nephropathy, i.e., 4 with unilateral renal hypoplasia, 3 with polycystic kidney, and 3 with renal agenesis. In the uropathy group, 43 were with hypospadia, 22 with primary reflux vesicoureter, 18 with neurogenic bladder, and 17 with ureteropelvic junction obstruction. The complications found were urinary tract infection (71.2%), chronic renal failure (15.7%), hypertension (3.7%), and acute renal failure (1.5%). Consanguinity, familial disorders, maternal diseases, x-ray exposure and abortion efforts were found in a small proportion of patients. History of drug or herbs use in the first trimester of pregnancy was found in a large proportion of patients, mostly took analgesics (especially acetaminophen). In conclusion, uropathy disorders were much more common than congenital nephropathy. The most common complication was urinary tract infection, followed by chronic renal failure, hypertension, and acute renal failure.


Background Diagnosis of malignant ascites is a clinical challenge. The gold standard method for diagnosis is with cytology; however, it has low sensitivity, is observer-dependent, and may require repeated paracentesis. Recently, some studies showed that high ascitic fluid cholesterol level could be a marker of malignant ascites and thus can differentiate between benign and malignant ascites. This study aimed to assess and evaluate the diagnostic accuracy of ascitic fluid cholesterol level in differentiating malignant from non-malignant ascites. Methods We prospectively studied patients of ascites, who were admitted in from February 2019 to July 2019. Ascitic fluid cholesterol of all patients was sent along with cytology for malignant cells. Malignancy was proven by tissue diagnosis (peritoneal biopsy or EUS guided abdominal lymph node FNA or cytology of ascitic fluid). Patients with spontaneous bacterial peritonitis, tubercular ascites and pancreatic ascites were excluded. Results A total of 50 patients of ascites were included in the study, and of these 11 patients had malignant ascites as proved by peritoneal biopsy or EUS guided abdominal lymph node biopsy or by ascitic fluid cytology. On taking a cut-off of 30 mg/dL of ascitic fluid cholesterol level, it was found that 9 of 11 patients (81%) of malignant ascites had high cholesterol values; however, only 8 of 39 patients (20.5%) of non-malignant ascites had high cholesterol values (p Conclusions Ascitic fluid cholesterol has high negative predictive value for ruling out malignancy-related ascites and thus can be used as an excellent biochemical investigation to rule out malignant ascites.

Encryption algorithms are becoming more necessary to ensure data is securely transmitted over insecure communication channels. FOX is a recently developed algorithm and its structure is based on the already proven IDEA (International Data Encryption Algorithm) cipher. FOX is a symmetric (private key) block cipher. Its top-level structure uses the Lai-Massey scheme and the round functions used in the scheme are substitution permutation networks (SPN). Its flexibility lies in the fact that it can be efficiently implemented in hardware and software. We report some of the first results of implementing the cipher on an FPGA.


Objective To investigate the dynamic changes of serum Cystatin C in neonates with different gestation age(GA) and day-age.Methods Sixty neonates were divided into 5 groups according to GA which were ~32,~34,~37,~40 and 40 weeks respectively,each group including 12 cases.One hundred and twenty neonates were divided into 6 groups according to day-age which were ~1,~3,~5,~7,~14 and ~28 days respectively,each group including 20 cases.The Cystatin C levels were compared among groups.The serum Cystatin C levels were measured with particle-enhanced immunoturbidimetry.Results The Cystatin C level of 5 groups with different GA were(1.25±0.40),(1.34±0.59),(1.20±0.24),(1.12±0.28) and(1.24±0.29)?mg/L respectively,showing significant difference among 5 groups(P0.05).The Cystatin C level of 6 groups with different day-age were(1.30±0.34),(1.28±0.42),(1.22±0.37),(1.29±0.37),(1.28±0.46) and(1.18±0.35)?mg/L respectively.There were no significant difference among 6 groups(P0.05).Conclusion The serum Cystatin C level is stable,the GA and day-age have not influence upon it in neonatal stage.Cystatin C may be an index to evaluate the function of the glomerular filtration rate in neonate.


The recent Omnidirectional MediA Format (OMAF) standard specifies delivery of 360° video content. OMAF supports only equirectangular (ERP) and cubemap projections and their region-wise packing with a limitation on video decoding capability to the maximum resolution of 4K (e.g., 4096x2048). Streaming of 4K ERP content allows only a limited viewport resolution, which is lower than the resolution of many current head-mounted displays (HMDs). In order to take the full advantage of those HMDs, this work proposes a specific mixed-resolution packing of 6K (6144x3072) ERP content and its realization in tile-based streaming, while complying with the 4K-decoding constraint and the High Efficiency Video Coding (HEVC) standard. Experimental results indicate that, using Zonal-PSNR test methodology, the proposed layout decreases the streaming bitrate up to 32% in terms of BD-rate, when compared to mixed-quality viewport-adaptive streaming of 4K ERP as an alternative solution.


The article proposes a solution to the scientific and applied problem of decision support automation in case of determined resource provision of civil defense forces for extinguishing forest fires. This topic is of great relevance both in peacetime and in the conditions of the current armed aggression of the Russian Federation against Ukraine. The solved task is an important element of resolution the more complex problem of prompt response to emergency situations in the ecological and technogenic spheres. To solve this problem, a software environment for automated decision-making support by experts is proposed based on the integration method, which provides structuring of data, support of expert judgments, and visualization of decision-making processes. The functionality of this software environment is considered on the example of the use of the integration expert method and relevant information technologies to determine the resources of aviation groups for the purpose of forming a plan of operational response to the elimination of forest fires. A hierarchical model of the problem is given in accordance with AHP requirements. Also, in order to increase the effect of the conducted modeling and ranking of alternatives, the use of a network model of the problem and ANP application (which is a AHP development) to support decision-making are proposed. The ANP implementation is illustrated using the freely distributed SuperDecisions software. The developed scientific and practical approaches and toolkit are intended for functioning in operational units of the state service for emergency situations, but they can also be used in other power structures. The obtained results are aimed at increasing the level of environmental safety in forest areas and can be used to support nature management in different regions.


Mining right is a near article right.In theory it makes the state possessory title to mineral disappear while in practice it is a dark way to lose the state capital.The reason of being near article right is the unclear object.The object of mining right is covered by the title to mineral,abstract mineral and special public right.In fact the object is mineral separated from the earth.Therefore,it should be an autonomous article right.


Resection of the tracheal carina presents special problems of reconstruction. We recently treated a 46-year-old male with primary carinal squamous cell carcinoma removed successfully by wedge resection.Partial wedge resection of four cartilagenous rings of the lower trachea and the carina was performed, and a primary side-to-end anastomosis was made between the carina and the shortened right main bronchus.With plastic reconstruction, the suture line of the upper border of the tracheal defect assumed the shape of an inverted T. The postoperative course was uneventful. The patient was discharged 50 days after the operation.Bronchoscopic findings six months after operation showed no stenosis or granulation of the new carina which formed two bifurcations.

Colostrum is the first milk produced by a female mammal. It is high in protein, carbohydrate and antibodies. People are constantly looking for healthier food options including immune enhancing foods. Ice cream is a popular dairy dessert and the influence of colostrum on ice cream characteristics is not known. The objective was to study the impact of various amounts of colostrum on the key attributes of ice cream. Ice creams were manufactured with 0, 1.5, 3.0 and 4.5 g colostrum per pint (473 mL) of ice cream. Ice cream manufacture was replicated three times. Colostrum incorporation increased aerobic counts, apparent viscosity, but decreased meltdown resulting in slower melting of the ice creams and had no influence on flavor. In an attempt to make healthier ice creams, colostrum incorporation can be recommended in ice cream manufacture.


A powerful automatic test generation system which uses a novel nine-valued relaxation algorithm is presented. This algorithm, which brings together the relaxation technique from circuit simulation and a nine-valued algebra from sequential circuit test generation, is applied to the strongly connected DC coupling components so that for every possible choice of node values a stable state could be achieved through relaxation. Circuits which use bidirectional transistors and depend on the transistor strengths for correct operation are properly handled by this algorithm. A method called DC path sensitization is used to detect the stuck-at, stuck-on, stuck-open and bridging faults for CMOS transistors. The algorithm has been implemented in C++ and preliminary results are very promising. The algorithm can easily be extended to different circuit models and other technologies, or be incorporated into a higher level test generation system.<<ETX>>


Many works, both theoretical and empirical, have recently considered the role of social relations in the labor market. A number of them points out that job access through contacts sometimes considerably varies according to the foreign origin of workers. Differences in the use and the efficacy of social relations according to workers' origin result from the variation of individual's socio-demographic characteristics of each group, from the behavior of employers and employees transmitting job offers as well as from some contextual factors. We propose a literature review on the main findings of these recent researches. When it is possible, we illustrate our comments through the original French Trajectories and Origins (2008) dataset.


In order to show the principle viability of a recently proposed relativistic positioning method based on the use of pulsed signals from sources at infinity, we present an application example reconstructing the world line of an idealized Earth in the reference frame of distant pulsars. The method considers the null four-vectors built from the period of the pulses and the direction cosines of the propagation from each source. Starting from a simplified problem (a receiver at rest) we have been able to calibrate our procedure, evidencing the influence of the uncertainty on the arrival times of the pulses as measured by the receiver, and of the numerical treatment of the data. The most relevant parameter turns out to be the accuracy of the clock used by the receiver. Actually, the uncertainty used in the simulations combines the accuracy of the clock and the fluctuations in the sources. As an evocative example the method has then been applied to the case of an ideal observer moving as a point on the surface of the Earth. The input has been the simulated arrival times of the signals from four pulsars at the location of the Parkes radiotelescope in Australia. Some substantial simplifications have been made both excluding the problems of visibility due to the actual size of the planet, and the behavior of the sources. A rough application of the method to a three-day run gives a correct result with a poor accuracy. The accuracy is then enhanced to the order of a few hundred meters if a continuous set of data is assumed. The method could actually be used for navigation across the solar system and be based on artificial sources, rather than pulsars. The viability of the method, whose additional value is in the self-sufficiency, i.e. independence from any control from other operators, has been confirmed.

Most studies of land‐atmosphere coupling have focused on bivariate linear statistics like correlation. However, more complex dependencies exist, including nonlinear relationships between components of land‐atmosphere coupling and the transmutability of relationships between soil moisture and surface heat fluxes under different environmental conditions. In this study, a technique called multivariate mutual information, based on information theory, is proposed to quantify how surface heat fluxes depend on both surface energy and wetness conditions, that is, net radiation and soil moisture, seasonally across the globe using reanalysis data. Such interdependency is then decomposed into linear and nonlinear contributions, which are further decomposed as different components explainable as the unique contribution from individual surface conditions, redundant contributions shared by both surface conditions, and the synergistic contribution from the concurrent action of net radiation and soil moisture. In reanalysis data, the dependency linearly contributed from soil moisture bears a similar global pattern to previously identified hot spots of coupling. The linear unique contributions of net radiation and soil moisture are mainly nonoverlapping, which suggests two separate regimes are governed by either energy or water limitations. These patterns persist when the nonlinearity is superimposed, thus reinforcing the validity of the land‐atmospheric coupling hot spot paradigm and the spatial division of energy‐limited as well as water‐limited regions. Nevertheless, strong nonlinear relationships are detected, particularly over subtropical regions. Synergistic components are found across the globe, implying widespread multidimensional physical relationships among net radiation, soil moisture, and surface heat fluxes that previously had only been inferred locally.


ABSTRACT The selection of an energy-efficient building facade system, as one of the most important early-stage design decisions, plays a crucial role in reducing building energy use by controlling heat transmission between outdoor and indoor environments. This paper aims to evaluate the feasibility and applicability of gradient boosting machines in estimating the energy savings of different facade alternatives in the early-stage design of building facades. The energy performance of two competing facade systems was estimated for different scenarios using building energy simulations (i.e. EnergyPlusTM ). Three gradient boosting machines were developed based on the data collected from the simulation of thirteen building types in fifteen different locations (i.e. 195 scenarios). The prediction performance of gradient boosting models was compared with the building energy simulation results of two new building models that were not used in the database development phase to validate the models. Moreover, the prediction power of the trained gradient boosting models was compared with three common prediction models (i.e. Artificial Neural Networks, Random Forest, and Generalized Linear Regression) based on several performance metrics. The results showed the superiority of gradient boosting machines over other models in estimating total site energy savings, heating energy savings, and buildings' cooling energy savings.

There is a great impact on power flow when distributed generation( DG) is introduced into the distribution network. Various DGs are analyzed and the corresponding models are discussed combined with power flow calculations. By introducing the sensitivity impedance matrix correction method and updating the reactive power injection of PV nodes,combined with the characteristics of the radial distribution network,a layer-by-layer back/forward power flow calculation based on the sensitivity impedance matrix correction method is proposed. The proposed method solves the problem that the traditional back /forward power flow calculation is failure for dealing with PV nodes,or dealing with the distribution network contained various DGs. Simulations with IEEE 33 nodes test system included multi-type DGs are carried out to verify the availability and rapidity of the proposed method. Finally,the stability of the proposed method is verified by various cases.


Inasmuch as the cases of acute pleurisy with serous effusion, the cases of hypodermoclysis, and experiments with saline injection into cortical bone and periosteum present swelling of periosteum and bone with enlargement of lacunae and interlamellar spaces and activity of the bone cells and periosteal cells, the writer judges these to be a preliminary step to the formation of new bone. The bone is softened, calcium salts are carried into surface-degenerating tissues, and the modified, slowed, congested circulation stimulates the formation of new bone.

An analysis of abundant statistical and experimental data collected on the basis of many years of experience of maintenance of railroad rails subjected to various technologies of surface hardening is presented.


Traveling wave fault location devices record fault data and non-fault interference clutter using low-threshold variation start. However, the main information of traveling wave ranging is from fault early instantaneous data. So the most basic condition of traveling wave ranging is to screen out fault early instantaneous data automatically. This paper proposes a method of sinusoidal fitting to automatically screen out fault early instantaneous data. The current traveling data recorded by traveling wave fault location device is divided into two sections, the sine fitting of two sections is calculated respectively. Then modal eigenvalues of two pieces are calculated according to the degree and amplitude of sine fitting. If the calculated modal eigenvalue is greater than the set threshold value, it is judged as a failure early instantaneous data that contains valid information. On the contrary, it is regarded as the non-fault early instantaneous data. A large number of calculations show that the proposed transmission line traveling wave data automatically screening method based on sine fitting is feasible, accurate and reliable.

A method of obtaining quantitative two-dimensional (2D) maps of strain by the convergent beam electron diffraction technique in a transmission electron microscope is described. It is based on the automatic acquisition of a series of diffraction patterns generated from digital rastering the electron spot in a matrix of points within a selected area of the sample. These patterns are stored in a database and the corresponding strain tensor at each point is calculated, thus yielding a 2D strain map. An example of application of this method to cross-sectioned cells fabricated for the 0.15 μm technology of flash memories is reported.


The fatigue growth of cracks emanating from smooth specimens with stress concentration was investigated. A two-term model of fatigue for step-by-step evaluation of crack propagation from very short cracks to fracture was used to predict the crack growth. Base metal of T1 steel (ASTM 514F) was tested. Growth rates were monitored using the Direct Current Potential Drop method. System calibration was made using an accurate model of the specimen and a numerical solution of the Laplace equation for the electric potential. The two-term model is presented and discussed, and life predictions are compared with experimental results.


Dislocation of the talonavicular joint is a rare occurrence. The swivel subtype dislocation is reported throughout the literature. Most are the result of an abductory or adductory force applied to the forefoot. Most authors report good functional results after a myriad of treatment options. Presented is a case of a 46 year -old male who sustained a medial swivel type dislocation of the talonavicular joint with concomitant fractures of the navicular and cuboid after a low-energy axial load to the foot. The case discusses some of the common issues revolving around the care of this type of dislocation.


Present experiment was conducted to study the effect of different feeding regimes on productive performances of HF × Kankrej crossbred cows. The study was conducted on 18 crossbred cows which were distributed into three treatment groups comprising of 6 animals each. Animals of T1 (Farmers' feeding) group were maintained as per the feeding regime followed by small and marginal farmers in India. Animals of T2 (Modified feeding) group comprised of feeding with scientific interventions. Animals of T3 (Farm feeding) group were fed as per feeding practices followed at Livestock Research Station, Anand Agricultural University. Milk yield and 4% Fat Corrected Milk (FCM) yield was significantly higher in T2 and T3 as compared to T1 group. Lactation yield was highest in T3 followed by T2 and T1 groups. Average total solid of milk was significantly more in T3 as compared to T1 and T2 groups. Milk fat was maximum in T3 followed by T2 and T1 groups which did not differ significantly among each other. SNF, protein and lactose content of milk was found significantly higher in T3 as compared to T1 and T2 groups. Milk salt was highest in T3 followed by T2 and T1 group which differed significantly among each other. It may be concluded from the present study that feeding regime significantly influenced productive performances of crossbred cows as modified feeding group performed better over farmers feeding group and at par with farm feeding group.


One of the most distinguishing features of contemporary globalisation is production fragmentation, a splitting up of the manufacturing of a good into several different stages. Production fragmentation creates new opportunities through vertical specialization; a country incapable of mastering the entire production process may specialize in the manufacturing of one separate part. The aim of this thesis is to examine to what extent international integration affects a country's ability to engage in vertical specialization in an industry characterized by production fragmentation. The analysis focuses on the european integration process over the last decade, where countries in eastern Europe with relatively low labour costs have been integrated with more capital abundant western economies. The sector examined is telecommunication, an industry permeated with a far-reaching fragmentation of the production process. The result indicate that the degree of integration, defined as a reduction of the transaction costs, may be of decisive importance for a country's ability to take part in international production networks.


Codecademy is an example of a successful and disruptive player in the online education space. This work describes the structure, content, and experience of working through a Codecademy Pro Intensive module and compares it to the offline approach in a similar domain. Existing taxonomies are insufficiently general to explain its success, and a new taxonomy based on Legitimation Code Theory is developed to compensate. This taxonomy is arguably more meaningful and more general than those presently in use.

In the design of Diaphragm Wall support we just consider the action of earth pressure,then a safety factor which is greater than one will be multiplied to offset the impact of complex dynamic load at construction site according to the experience of the designer.However,there are no data to reflect the impact to the support after dynamic load,this paper is to measure and analyze the force characteristics of the support under dynamic load.Three measuring points of beam support was selected,the strain of the upper and lower surface of the beam was to be measured using electrometric method of gauges.The force case of the beam support was simplified to axial force and bending moment at both ends.The axial force and bending moment could be calculated after the data of strain measured yet.The results show that the impact to the beam support of dynamic load is very small compared with the earth pressure combined with the results of static analysis.Therefore,the safety factor should be selected reasonably with a large number of measured data and should not be too large,otherwise it will result in material waste and hour of delay.


Economists have long debated the driver(s) of business cycles, attempting to answer this question through the lens of structural vector autoregressions (SVARs) and estimated DSGE models (Galı́, 1999; Smets and Wouters, 2007). More recently, a range of variance-maximizing SVAR estimators have been used to identify some of these potential drivers, including technology shocks (Francis et al., 2014), "news" shocks (Barsky and Sims, 2011), and other attempts to dissect the business-cycle anatomy (Angeletos, Collard and Dellas, 2020). However, identification performance is poor when shocks other than the target of interest also play a nontrivial role in driving volatility at the targeted horizon or frequency, thus confounding the estimation. The result is that these identifications capture a hybrid shock rather than a dominant shock (Dieppe, Francis and KindbergHanlon, 2021).


In this position paper we propose to extend an existing delegation-based machine model with concurrency primitives. The original machine model which is built on the concepts of objects, messages, and delegation, provides support for languages enabling multi-dimensional separation of concerns (MDSOC). We propose to extend this model with an actor-based concurrency model, allowing for both true parallelism as well as lightweight concurrency primitives such as coroutines. In order to demonstrate its expressiveness, we informally describe how three high-level languages supporting different concurrency models can be mapped onto our extended machine model. We also provide an outlook on the extended model's potential to support concurrency-related MDSOC features.

Hydrogen bond competition was studied in 21 X-ray crystal structures of N-X-phenyl-N′-p-nitrophenyl urea compounds (X = H, F, Cl, Br, I, CN, C≡CH, CONH2, COCH3, OH, Me). These structures are classified into two families depending on the hydrogen bond pattern: urea tape structures contain the well-known α-network assembled via N−H···O hydrogen bonds; however, in nonurea tape structures the N–H donors hydrogen bond with NO2 groups or solvent O acceptor atoms. Surprisingly, the urea C═O hardly accepts strong H bonds in nonurea type structures sustained by urea···nitro and urea···solvent synthons. The carbonyl group accepts intra- and intermolecular C−H···O interactions. The molecular conformation and H bonding motifs are different in the two categories of structures: the phenyl rings are twisted out of the urea plane in the tape motif, but they are coplanar in the nonurea category. Even though hydrogen bond synthon energy and urea carbonyl acceptor strength favor the N−H···O tape structure, the dominant patt...


Abstract : A shielding theory based on Impedance Boundary Conditions is developed and used to obtain formal expressions for the fields transmitted to the interior of a generalized metallic structure from an arbitrary, external, time harmonic, electromagnetic source. The structure is an assemblage of planar sheets that may be penetrated by a finite number of narrow rectangular slots. It includes both a single sheet (continuous or slotted) and a rectangular enclosure (continuous or slotted) as special cases. Explicit expressions are then derived for the transmitted electric and magnetic fields at points on the inside surfaces of plane sheets (continuous and slotted) and rectangular enclosures (continuous and slotted) when these structures are exposed to fields from elementary electric and magnetic dipoles and small rectangular loop antennas. These expressions are then used to obtain the shielding effectiveness of sheets and enclosures.


We confirmed that, for electronic paper that uses the cholesteric liquid crystal method, a high reflectance and contrast ratio were obtained by applying cross‐rubbing of appropriate rubbing strength to a high pretilt angle alignment layer.


Fish hydrolysate contains hydrolyzed protein which comprised of peptides and free amino acids that are easily digested and absorbed by fish. This study aimed to determine the effectiveness of fish hydrolysate in improving feed efficiency and growth of coral trout. Five experimental diets were formulated to contain 47% protein and 12% lipid with different sources and levels of fish hydrolysate. Diet-1 and diet-2 were added with crustacean hydrolysate at 2% and 4% levels, respectively. Whereas diet-3 and diet-4 were supplemented with 2% and 4% of tuna hydrolysate. Diet-5 was formulated without fish hydrolysate supplementation (control). The diets were prepared as dry pellet with 3 mm diameter. Coral trout juveniles were produced in the hatchery of Institute for Mariculture Research and Fisheries Extension (IMRAFE), Gondol-Bali with the average body weight of 7.6 ± 0.9 g. The juveniles were maintained in 15 fiber tanks, 400L in volume, with a density of 40 fish/tank. The experiment was designed with a completely randomized design (CRD) with 5 treatments (different diets) and 3 replications for each treatment. The fish were fed the experimantal diets three times every day at satiation level for 84 days of feeding experiment. Results of the experiment showed that increased supplementation of fish hydrolysate from 2% to 4% in diet tended to improve fish growth performance. However, the best growth performance, in term of weight gain (WG) and specific growth rate (SGR), was obtained in fish fed diet supplemented with 4% crustacean hydrolysate. This growth performance was significantly higher than of the other treatments (P<0.05). The best feed efficiency (FE) and protein efficiency ratio (PER) were also obtained in fish fed diet supplemented with 4% crustacean hydrolysate. The results of the present study showed that supplementation of 4% crustacean hydrolysate in diet effectively improved the growth and feed efficiency of coral trout.


In this contribution we describe the work on the parallelization of the Monte Carlo code CORSIKA to master the challenges of simulations for development of an Extensive Air Shower initiated by cosmic ray particles at the highest energies of 10 eV. We have implemented workflow system for parallel execution of CORSIKA on distributed computing infrastructures and make preliminary tests simulations for energies up to 10 eV. It allows us to estimate computational needs and challenges for productive simulations at higher energies to escape possible overflows when using parallel job scheduling systems. Introduction One of the problems in simulating Extensive Air Showers (EAS) initiated by cosmic rays at the highest observed energies comes from the huge number of 10 particles which are created within the avalanche by the consecutive interactions with air. Their fate is determined by the flight path between their creation and their interaction or decay, and their nature and energy determines the number, types, energies and directions of the secondary particles generated in the interactions. These stochastic processes are well modelled by Monte Carlo (MC) methods to get correctly not only the mean values (which might be given eventually by analytical approximations) but also the fluctuations and correlations of the measurable shower observables as e.g. lateral distribution of the particles at ground or energy spectra of those particles at different distances to the shower axis. A solution of following this huge number of particles might be the parallelization of the MC code CORSIKA (COsmic Ray SImulations for KAscade) (Heck et al. 1998) to treat independent sub-showers by different cores in parallel. Already in an early stage of the development of the CORSIKA code several possibilities to circumvent the long CPU times which increase nearly linearly with increasing energy of the initiating cosmic particle, were considered (Gils et al. 1993) including various structures of a multi-Transputer computer farm (Gils et al. 1989). Today the availability of multi-core processor systems has revived the parallelization ideas. To master challenges of productive usage of current and future high-end multi-core processors systems an innovative research and support structure, so-called Simulation Laboratories (SimLab), are currently being established at different supercomputing centres in Germany. In particular "SimLab Astro& Elementary Particle Physics" (SimLab A&E Particle) at SCC of KIT is providing support on parallelization of scientific application CORSIKA and porting it into up-to-date distributed and super-computing infrastructures in Europe (Thiara, Poghosyan und Schmitz 2009).


The study approach is one of the factors that affect academic achievement. There are few studies that show what factors predict the study approach and how it predicts academic achievement. This study aims to investigate whether there is a significant difference between the study approaches of education faculty students according to their gender and major and whether the student's study approach is a significant predictor of their academic achievement or not. The data of this survey study were collected from 476 students in various departments in the faculty of education during 2017-2018 academic year. The data related to the general achievement scores of the participants and gender were collected using a personal information form. To calculate the deep and superficial approach scores, the Studying Approaches Scale was used. 10 items of the Studying Approaches Scale, which consisted of totally 20 items, were related to measure the deep approach, while 10 were related to superficial aproach. A factorial ANOVA and multiple regression analysis were used to answer the research question. The results show that the departmental variable makes a significant difference on the deep approach scores, whereas gender does not. On the other hand, both gender and program variables recorded on the surface approach scores do not make a significant difference. The results of regression analysis show that the academic achievement of deep approachand surface approach scores are significant predictors. It was also found that the deep approach scores predicted the Studying Approaches Scale positively, and surface approach negatively; 10% of the variability observed in Studying Approaches Scale were explained by these two variables.


A structural parameter identification and damage detection approach using displacement measurement time series is proposed, and the performance of the approach is validated experimentally with a frame structure model in a healthy condition and with joint connection damages. The proposed approach is carried out using two neural networks: one is called time-delay neural network (TDNN) and the other is called traditional neural network (TNN). The theoretical basis and the selection of the input and output of the TDNN and the TNN are explained. The performance of the proposed methodology for damage detection of the frame structure model with different joint damage scenarios is introduced by direct use of displacement measurement under base excitations. A simulation study has been carried out for the incomplete measurement data. The proposed approach provides an alternative way for damage detection of engineering structures by direct use of structural dynamic displacement measurements.

Data of PM10 and PM2.5 collected during the heating period show that the aerosol mass concentration of PM10 and PM2.5 are variable diurnally and monthly. The PM10 average value is 253.1μg/m3, 1.9 times exceed that of the standard 2 daily value issued by the state in the year of 1996. The variation magnitude of concentration of PM2.5 is 8.9-276.2μg/m3, and the average value is 145.2μg/m3, which exceeds that of the data got from 1999-2000 around 38.4%. The relationship between the polluting sources and influence factors are herein dealt with in this paper. It was suggested that the wind speed, temperature and humidity are quite critical in this regard.

Through some unexpected and still-unidentified form of molecular texting, the herpes simplex virus (HSV) induces a hormone-like stimulation of cellular DNA replication in nearby, uninfected cells, according to Peter O'Hare of St. Mary's Medical School, Imperial College in London, United Kingdom, and his collaborators. Details appeared 26 August 2015 in the Journal of Virology (doi:10.1128/JVI.01950–15/).


UAVs (Unmanned Aerial Vehicles) are increasingly being used for all sorts of tasks, of which UAV video shooting is a famous example. In order to reduce the cost of buying an UAV, there is the possibility of making your own UAV. The aim of this work was to make an UAV operated by the Arduino as the main "brain" instead of a commercial flight controller. The successful and rather cheap construction of the Arduino UAV proved that everyone can have their own UAV with a little effort.


When you came father raised his knees to his face tightly, the pain knotted the body so you could begin swallowing him whole. Later, in the straightening, you yellowed him?his cheeks waxed into a cheap make-up, his body tucked in and neat. The buttons of his only suit loosened in their edged stitching, ready to be thumbed out. You were there listening in while I greeted his mourners: Jeff, who sells used cars, shook my hand as if he had just closed a deal. Rose, who had cooked the whole family dinner the day before, told me: "Don't worry, son?you have us. Don't worry." The rest of your guests found seats as the men of the mortuary stood near, for they were staging a drama while they pointed to our spots, cuing us. We, the actors, learned our parts well. That winter you knew whom you wanted when your thorns brushed our screens. The keys in the locks jingled as if you had opened the door and played his song: "Guadalajara." After your embrace you left your sand tracks on his palms and face. You are what marks our seasons.


The paper attempts to show that the arrival and attendance processes and the subsequent loading and unloading of the vehicles in the waterway terminals can be studied like an intersection with traffic lights. The main critical points located in the terminal- bottlenecks - have been identified, where a large number of retained passengers can be found, contributing to the accumulation of queue. The vehicle arrival and service processes were analyzed using the queuing theory models. Beyond these, the models can also quote methods for setting up traffic signal time. To validate the study, data at the San Joaquim's urban waterway transport terminal were collected.


The state of organization of medical aid for patients suffering from diabetes mellitus at the first, ambulatory-policlinic stage has been studied with the aim of preventing its ophthalmological complications. An opinion poll held among general practice doctors, endocrinologists and ophthalmologists, as well as among patients, showed that level of the work of family polyclinic doctors for prophylaxis and early treatment of ophthalmological complications from diabetes mellitus is not quite satisfactory. There are also presented ten-year data on the disability caused by ophthalmodiabetes, peculiarities of its formation depending on a disability group, disabled person's age, the type of diabetes mellitus as well as a frequency of its detection by year. It is shown that the level of disability from ophthalmological complications of diabetes mellitus is relatively low, however, active working age people with a severe degree of disability, i.e. total loss of sight, prevail among the disabled people. In such cases, as a rule, not only the sick person himself drops out of labor activity, but some of their family members has to nurse him that causes significant economic loss.


During recent years, LMS Technologies has been working to enable designers to have tools that would make them aware of the sound quality likely to result from 'virtual' vehicle models. The recently completed international OBELICS (OBjective EvaLuation of Interior Car Sounds) research project was to develop an understanding of exactly what is involved in getting the sound of a car 'right'. One of its results was the development of a prototype sound-quality tool to enable designers to change parameters or modify the throttle/rpm profile and listen to the results. Breakthroughs are required in time domain transfer path analysis (TPA) as a complement to frequency domain TPA, virtual sound modelling, and 'driver-in-the-loop' jury testing; this paper focuses on the first two aspects. One problem is to explain why the perceptions of sound quality of diesel and petrol engines are very different, even though there is little difference between their frequency spectra. A good perception of in-vehicle sound requires the presence of high as well as low frequencies, and non-harmonic components in the lower frequencies. A new experimental method was developed and tested, with promising results, and a simplified general vehicle model was built to calculate the rpm evolution, starting from the current speed.

In this paper, a frequency-domain equalization architecture for the downlink over a space-time block coded MIMO-CDMA system is proposed. This architecture exploits transmit diversity by equally dividing the N T (N T =2Q, Q is a positive integer) transmit antennas into Q groups and implementing an Alamouti-like space-time block coding scheme for each group. At the receiver, the single-carrier minimum- mean-square-error frequency-domain equalization is combined with the successive interference cancellation to combat various interferences resulting from frequency-selective fading channels under multi-antenna and multi-user conditions. It is shown that our proposed architecture significantly outperforms the conventional MIMO-CDMA structures.


The effects of aluminium (0, 0.5, 1.0, 2.0 p.p.m.) on the dry matter production (tops and roots) and chemical composition of five tropical and six temperate pasture legumes grown in a cultu1.e solution containing 2 p.p.m. phosphorus were ascertained. The tolerances of the tropical species to aluminium were in the order Desmodiunz uncinatum = Macroptilium latlzyyuoides = Lotonis bainesii = Stylosanthes humilis = Glycine wightii > Medicago sativa, and temperate species in the order Trifolium rueppellianum= Trifolium sernipilosum > Trifolium repens = Medicago scutellata = Medicago truncatula = Medicago sativa. In the tolerant species the yield of plant material from the 0.5 p.p.m. aluminium treatment was greater than from the control. The top/root weight ratios of the tolerant species were unaffected by treatment; the ratios of the sensitive species were reduced. The effect of aluminium treatment on aluminium, nitrogen, phosphorus, potassium, calcium, magnesium, and sodium concentrations in the plants are given. The principal nutrients to be affected were calcium and phosphorus. Aluminium treatment reduced the calcium concentrations in the tops of all species and there were reciprocal relationships between calcium, magnesium, and potassium concentrations. In the sensitive species aluminium treatment reduced phosphorus in the plant tops and roots; in some of the tolerant species the intermediate aluminium treatment increased the phosphorus concentration in the plant tops; however, the high aluminium treatment reduced the phosphorus concentration.


Abstract This work reports the first investigation on the physical vapor deposition of thin films of tin sulfide doped lead sulfide (SnS:PbS). In-situ synthesis route using diethyldithiocarbamate (DTC) ligand was adopted for SnS-DTC, PbS-DTC and SnS:PbS-DTC complex formation. PbS-DTC and SnS:PbS-DTC expressed an average crystallite size of 30.98 and 29.74 nm, respectively shown by X-ray diffraction (XRD) analysis. A face centered cubic geometry was revealed from XRD. Ultraviolet visible spectrophotometry expressed a direct and indirect band gap of 3.4 and 3.2 eV, respectively for SnS:PbS-DTC. A smooth morphology with presence of larger agglomerated particles was disclosed by scanning electron microscopy for SnS:PbS-DTC thin films with 615 nm thickness. SnS:PbS-DTC thin films expressed remarkable electrochemical behavior explored via cyclic voltammetry, linear sweep voltammetry and chronoamperometry showing an improvement in the photo-current response upon potential bias increment. The results of the current research indicated the potential of SnS:PbS-DTC thin films for utilization in different types of photovoltaic devices. Graphical Abstract


The aim of this study was to assess the level of knowledge, attitudes, and effect of covid-19 on marijuana users in the Sabon Zongo community during the Covid-19 pandemic in Ghana. The study employed a cross-sectional quantitative study design to assess the effect of Covid 19 on marijuana users . A redcap tool was used to collect the data and prepared it by editing, coding, transcribing, and cleaning. The data was analyzed using Microsoft Excel tool and SPSS version.25.1 and results were presented in descriptive statistics such as frequencies, percentages, tables, and figures . A total sample size of 218 participants took part in this aspect. A majority (50.5%) of the respondents were within the 21-25 age group. The results showed a high knowledge about Covid- 19 (40.5%) among marijuana users with an increase in marijuana intake during the pandemic season resulting in a 61.8% incremental jump in high rolls and a commentary reduction in the number of people smoking low rolls from 74.3% to as low as 12.5% during the same season. In conclusion, there was high knowledge about Covid-19 (40.5%) among marijuana users with an increase in marijuana intake resulting in a 61.8% increase in high rolls and a reduction in the number of low rolls from 74.3% to 12.5% during the same season. even though their attitudes remained unchanged.


Floods are one of the most recurrent and damaging natural disasters in cities in developing countries today. The city of Abidjan (economic capital of Côte d'Ivoire) is not immune to these disasters. Indeed, according to the ONPC (2014), floods have killed an average of 13 people each year since 2009. One of the causes of the worsening and recurrence of these disasters is the urbanization experienced by the city of Abidjan in recent years. This urbanization has resulted in an increase in waterproofed areas and at the same time an increase in the volume of runoff water. The main objective of this research is to study the dynamics of floods and to see the impact of human activities on the hydrological functioning of the Gourou and Bonoumin watersheds in order to anticipate the risks of flooding. To do this, several specific objectives have been assigned in this study. These are: (1) the morphometric characterization of each watershed ; (2) the cartographic and diagnostic of stormwater management works and the dynamics of land use as well as the study of the variability of rainfall relative to the resurgence of floods in each basin ; (3) the establishment of a geographic information system for the study of floods; and (4) the prospective study of the evolution of land use and the future hydrological functioning of the watersheds studied using scenarios in order to take measures to fight against floods. The equipment used is composed of rain gauges (for measuring the spatial variation of rainfall in each sub-basin), limnimetric scales (to measure the heights of water in rivers), a double-ring infiltrometer (to measure the infiltration capacity on the basins) and software (Goldsim for simulating the behavior of watersheds). The data used consist of climatic data (temperature, rain), historical data on the floods in Abidjan, land use data (satellite images), physical characterization data of the watersheds (slope, hydrographic network, sanitation network , rainwater management works, morphometric parameters of the basins. The methodology adopted consisted of (1) collecting historical data on past floods in Abidjan; (2) description of the environment during rainy events; (3) studying the morphometric parameters of the watersheds studied and also (4) the study of the evolution of rainfall. Thus, the results obtained made it possible to show that the Gourou and Bonoumin basins cover respectively an area of 27.42 km² and 46.37 km² and the Gravelius indices of the two basins are respectively 4.89 and 5.51. Each year, the risk of a flood occurring is 75% with an average of more than 500 million property damage. The level reached in flooded areas of about 1 meter and according to historical data about inundations in Abidjan, on average 16 people lose their lives each year.


A novel fast motion estimation algorithm called M-DAHS based on motion vector field,adaptive direction and half-pixel search was proposed.According to center-bias property and spatial-temporal correlation of the vector field,the threshold was applied to stop the stationary block from searching.The initial search point and strategy were adaptively selected based on motion type for non-stationary block.The search template has strong direction adaptability.The line-diamond search was used for the blocks with low motion activity,and the hexagon-diamond search for that with middle or high motion.After searching all the pixels,a cross priority search pattern was utilized for half-pixel search.Experimental results show that the proposed algorithm has good performance with high search speed and high precision,while the distortion is almost the same as full search algorithm.

Observing the planet with the aid of foreign soft ware as well as cartoon maded by myself, I discovered that the moving of Mercuty Venus Mars Jupiter Saturn is different with the sun moving in the sky when they superpose with the sun and clash to the sun. All these regulations are corresponding to the point of positive and negative principle in nature which are describe in "Wu Sheng Shi Cheng". Therefore, we can say that the black point and the white circle of "Wu Sheng Shi Cheng" indicate the relatively displacement of the five major planet and the Sun in a certain period of the time. They are astronomical phenomena.

Bronchiectasis unrelated to cystic fibrosis has been called an "orphan disease" and a "much neglected disease", having had a low profile until very recently. Part of the reason for this is the impression that the condition is uncommonly seen and is therefore of decreasing importance – particularly in the developed world – mainly as a consequence of childhood vaccination and the effective use of antibiotics for the management of respiratory tract infections. However, since the advent of high resolution CT (HRCT) scanning of the chest, the diagnosis of bronchiectasis is being made with increasing frequency throughout the world and the condition has become recognised as an important and common cause of respiratory disease. Bronchiectasis is important to recognise since it may cause severe and recurrent pulmonary infections, with associated permanent and progressive loss of lung function leading to significant morbidity and even premature mortality. For example, a recent mortality study conducted in England and Wales reported the number of deaths from bronchiectasis to be increasing by 3% per annum in the older age groups, and this despite likely underreporting – thus necessitating increased clinical provision for these patients to reverse this trend. Frequent exacerbations and/or delayed treatment are clearly associated with lung function decline – itself a mortality risk – whereas there is considerable and increasing evidence that progression of airway damage can be limited with intensive medical treatment even in patients who are predestined to have bronchiectasis, such as those with immune deficiency. Furthermore, in some children with bronchiectasis, resolution or considerable improvement of the changes seen on HRCT scanning of the chest have been noted, underlining the importance of early diagnosis and treatment of the condition. It is for these reasons that early diagnosis and institution of appropriate care are essential. Therefore, it is pleasing to note the resurgence of interest in this condition culminating in the development of bronchiectasis management guidelines – one of which has been highlighted with a primary care summary in this issue of the PCRJ. The first step in primary care is to recognise that an individual patient may have bronchiectasis and that one needs to confirm the diagnosis. Although symptoms are very non-specific, the diagnosis should always be suspected in an individual presenting with cough productive of sputum, and/or unexplained haemoptysis. The diagnosis should also be considered in children with "asthma" that responds poorly to treatment, and similarly in adults with "chronic obstructive pulmonary disease (COPD)". The plain chest X-ray – which is recommended for all patients – is not sufficiently sensitive for adequate diagnosis of the condition, and the use of bronchography has been replaced by HRCT scanning of the chest, which is currently considered the gold standard for bronchiectasis diagnosis. It is the more widespread use of HRCT scanning that has largely contributed to the recognition of the importance of bronchiectasis. Once a diagnosis is made, most patients (and especially the problematic ones) will require referral to secondary care for further assessment and evaluation for an underlying cause. Importantly, in both children and adults it has been conclusively shown that investigating patients with bronchiectasis for an underlying cause is very important since this leads to the identification of a treatable condition in more cases than was previously thought – leading to an alteration in therapy to target these conditions – and this can have significant prognostic implications. *Charles Feldman a Professor of Pulmonology and Chief Physician, Charlotte Maxeke Johannesburg Academic Hospital and University of the Witwatersrand, Johannesburg, South Africa

Second,Wha t is the nature of the ethnic war? third,What is the nature and function of the national marriage among the rulers of different Ethenic-groups? Fourth,What is t he similarities and dissimilarities between the national assimilation and nation al fusion? This article gives a brief and clear narrative on the representative and different ideas for above issues.


Abstract Reality and Appearance (in Wittgenstein). At the beginning of On Certainty, as its second entry, Wittgenstein makes a remark according to which the fact that something appears to me, or to all of us, to be so and so does not entail the fact that it is so and so. This looks like a straightforward philosophical claim made by Wittgenstein. This claim fits into a family of views on the nature of the relation between appearance and reality which in turn is related to a family of views concerning the nature of belief, knowledge and certainty. However, it is common experience with Wittgenstein's remarks that what appears to be a straightforward philosophical claim is actually no such thing. The essay follows that experience to a point where it becomes unclear what the remark about appearance and reality could possibly be if not a philosophical claim.

Drug discovery is a cost expensive and time consuming process. Approved drugs have favorable or validated pharmacokinetic properties and toxicological profiles. Therefore repurposing approved drugs to new diseases can potentially avoid expensive costs associated with the early-stage testing. In this work, we propose to integrate drug-drug, disease-disease, gene-gene and drug-disease associations to reposition the approved drugs. Firstly, multiple sources of data are integrated into three layers: the chemical/phenotype layer, the gene/machanism layer and the treatment layer. Secondly, the drug-drug and disease-disease similarities in three layers are respectively computed and then combined together. Finally, based on the hypothesis that similar drugs may treat similar diseases, we model the drug repositioning problem as an optimal problem and propose a semi-supervised graph cut (SSGC) algorithm to solve the problem. The experimental results show that integrating multiple sources of data can achieve better performances than only considering single kind of data, and our method outperforms three representative approaches. Moreover, the predicted top-ranked repositioned relations have been reported in literature, illustrating the usefulness of our method in practice. The predicted results are available at https://github.com/wgs666/SSGC.git.
