Binocular vision is an important branch of computer vision that processes images captured from two different cameras with different perspectives to obtain depth information of a scene. However, the stereo matching algorithm is complex and traditional platforms often struggle to meet real-time and accuracy requirements simultaneously. In this article, we implement a binocular vision system based on the idea of software-hardware co-design on the Zynq platform. According to the characteristics of the Zynq platform, the system's software and hardware functions are divided. The processing system (PS) is mainly responsible for flow control and binocular correction, while the programmable logic (PL) is responsible for parallel acceleration of the stereo matching algorithm. In the image acquisition part, we configure the format and output image timing using a designed camera acquisition module. In the stereo matching part, we design a semi-global stereo matching algorithm using Verilog language. Finally, we build a binocular vision system on the Zynq platform for testing. The experimental results show that the frame rate can reach 30fps when the input image resolution is 640×480, which satisfies the requirements of real-time and accuracy of the output disparity map.


The success of India's democracy has evoked widespread interest. It is rightly regarded as a postcolonial success story—a functioning democracy that has held free and fair elections and managed to remain pluralist and inclusive. Indian democracy has offered huge opportunities to confront and address the challenges on the development front through policies and practices evolved in the past six decades. Its numerous achievements notwithstanding, the failure to remove the division between the privileged and the rest is largely responsible for the inability to extend the reach of India's economic and social development. The persistence of inequalities of various kinds is a major contributory factor in holding back the full potential of democratic politics. What follows is not a comprehensive account or stocktaking of India's democratic experience and its impact on inequalities and vice versa. This lecture attempts to situate issues of inequality in the wider context of political democracy to explore the interaction between the two processes. It concludes with a brief discussion on the emerging relationship between democracy and inequality in the contemporary moment.


The classification of waste with neural networks is already a topic in some scientific papers. An application in the embedded systems area with current AI processors to accelerate the inference has not yet been discussed. Therefore a prototype is created which classifies waste objects and automatically opens the appropriate container for the object. The area of application is in the public space. For the classification a dataset with 25.681 images and 11 classes was created to retrain the CNNs EfficentNet-B0, MobileNet-v2 and NASNet-Mobile. These CNNs run on the current Edge AI -accelerator processors from Google, Intel and Nvidia and are compared for performance, consumption and accuracy. The result of these comparisons and shows the advantages and disadvantages of the respective processors and the CNNs. For the prototype, the most suitable combination of hardware and AI architecture is used and exhibited at the university fair KasetFair2020.

Although language may become impaired by dementia, communication with your loved one is still possible. Speak clearly and slowly in a quiet environment. Help them obtain hearing aids, if needed. Reading and writing may be beneficial for those who have hearing or speech problems and mild dementia. Speech therapy may also benefit those with mild dementia and trouble talking. Pictures can often compensate for a variety of comprehension and communication problems. Gestures, body language, facial expression, tone of voice, and other nonlinguistic and nonverbal communication can be useful, both in person and over a video phone. Lastly, remember that emotional communication is often preserved in dementia.


Photoremovable protecting groups (or "photocages" or "phototriggers") are light-sensitive chemical moieties that provide control over the release of any number of reagents in a variety of environments. Photocages can provide orthogonal external control over when, where, and how much of a biological substrate is activated in cells using light irradiation. All commonly used commercially available photocages respond to UV-light. Researchers at Iowa State University have developed photocages that respond to light in the visible spectrum, in a so-called "biological-window"


Survival of neutrophils is prolonged, and their function is preserved by simultaneously targeting multiple cell death pathways. Neutrophil preservation Granulocyte transfusion (GTX) is a therapeutic option for severe bacterial or fungal infection in neutropenic patients. However, GTX is limited in its clinical utility because of the short half-life of neutrophils and the lengthy process between neutrophil isolation from donors to transfusion into recipients. Here, Fan et al. developed a combined treatment targeting multiple cell death pathways called CLON-G, which they found promoted human and murine neutrophil survival for multiple days in vitro and sustained the function of those neutrophils. Furthermore, CLON-G–treated murine neutrophils were equally capable of clearing infections after transfer into neutropenic mice as freshly isolated neutrophils. Together, these findings suggest that CLON-G and other life span–extending treatments may be a strategy to improve GTX therapy. Clinical outcomes from granulocyte transfusion (GTX) are disadvantaged by the short shelf life and compromised function of donor neutrophils. Spontaneous neutrophil death is heterogeneous and mediated by multiple pathways. Leveraging mechanistic knowledge and pharmacological screening, we identified a combined treatment, caspases–lysosomal membrane permeabilization–oxidant–necroptosis inhibition plus granulocyte colony-stimulating factor (CLON-G), which altered neutrophil fate by simultaneously targeting multiple cell death pathways. CLON-G prolonged human and mouse neutrophil half-life in vitro from less than 1 day to greater than 5 days. CLON-G–treated aged neutrophils had equivalent morphology and function to fresh neutrophils, with no impairment to critical effector functions including phagocytosis, bacterial killing, chemotaxis, and reactive oxygen species production. Transfusion with stored CLON-G–treated 3-day-old neutrophils enhanced host defenses, alleviated infection-induced tissue damage, and prolonged survival as effectively as transfusion with fresh neutrophils in a clinically relevant murine GTX model of neutropenia-related bacterial pneumonia and systemic candidiasis. Last, CLON-G treatment prolonged the shelf life and preserved the function of apheresis-collected human GTX products both ex vivo and in vivo in immunodeficient mice. Thus, CLON-G treatment represents an effective and applicable clinical procedure for the storage and application of neutrophils in transfusion medicine, providing a therapeutic strategy for improving GTX efficacy.


Molecular data The data as provided by Syngenta make it evident that there is a year-to-year and site-to-site variation in the content of the additional proteins expression, and therefore shows that environmental conditions will impact the level of gene expression. Nevertheless, the expression of the gene construct and the functional stability of the gene construct were, for example, not tested under extreme climate conditions such as drought and flooding which are likely to occur under present ongoing climate change. Investigations under controlled environmental conditions should have been performed to determine the actual range of variation and to identify relevant impact factors. Further, the effects of the additional genes on the activity of the plants ́ genome and the plants ́ metabolism should have been investigated using methods such as metabolic profiling.


Nocturnal melatonin secretion is important for preservation of ß-cell mass and function. Knowing that type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by hyperglycemia caused by the elevated resistance of peripheral tissues to insulin, reduction in pineal melatonin and disturbances of insulin secretion by pancreatic ß-cells.  In this context, exercise is considered one of the most valuable non-pharmacological approaches for treatment of T2DM. Considering the beneficial role of melatonin on glycemic metabolism in physical exercise, we investigated the effects of moderate-intensity aerobic exercise plus melatonin on glycemic homeostasis, the morphology and architecture of pancreas in spontaneous T2DM animals [Goto-Kakizaki (GK) rats]. The results confirmed that melatonin alone reduced the mass of epididymal white adipose tissue (WAT); however, only the combination of melatonin and physical exercise significantly reduced caloric intake, body weight, WAT and improved glucose tolerance and insulin sensitivity in T2DM rats. This combination also reduced apoptosis of cells in pancreatic islets. We observed either melatonin or the combination was able to reduce insulinemia. However, only the combination improved the morphology of the pancreatic islets. Thus, we conclude that in GK rats, melatonin plays a crucial role in the functionality of the pancreas to improve insulin sensitivity of peripheral tissues and, consequently, to maintain the glucose homeostasis. In addition, the combination is more efficiency to improve glucose tolerance and integrity of pancreatic islets in GK rats than melatonin alone.


Recent productivity studies suggest the reallocation of output across plants (between effect) and the productivity growth at individual plants (within effect) are both important sources of productivity growth at the industry level. Interestingly, recent evidence has shown that trade liberalization is related to both effects. While a trade model with firm heterogeneity can explain the between effect, it can not reproduce the within effect. We add to this model the option for firms to costly adopt more productive technologies and show that plant productivity actually rises in response to lower trade costs. The selection effect of trade that some firms will be forced to exit following trade liberalization favours the reallocation of output across incumbent firms (between effect) and contributes to raise the exporters' market share. Therefore, a greater scale of operation amplifies the firm's return from costly productivity-enhancement investments and leads a greater proportion of firms to undertake process-innovations (within effect).


protocol for DNA isolation is outlined in Table 1. This protocol was used to isolate phage DNA from two different libraries and phage vectors. The first was a λEMBL3 genomic library of the house fly, Musca domestica. The second was a λZAP (Stratagene, La Jolla, CA, USA) cDNA library of Drosophila virilis. An aliquot of 2 μL resuspended DNA was used per individual restriction digest. As shown in Figure 1, this small volume was sufficient for restriction mapping and Southern hybridization. The effect of glycerol during cellphage growth was compared. Identical 50-mL cultures were prepared for inoculation with phage isolated from the same purified plaque. One flask contained LB with 0.3% glycerol as decribed above, and the second contained LB without glycerol. Following lysis and DNA isolation, total DNA yield was compared. Total DNA yield from the glycerol-supplemented LB was 1.0– 2.0 mg while the yield for LB only was 0.125–0.25 mg. Thus, glycerol seems to have a dramatic effect on the DNA yield from this protocol.


Zhisin clay is used as raw clay material in this study. This clay is mixed with Taitung area argillite to produce the backfill material for potential application as barrier for the disposal of low-level radioactive wastes. The interaction between concrete barrier and the backfill material is simulated by an accelerated migration test to investigate the effect of contacting concrete on the expected functions of backfill material. The results show backfill material close to the contact with concrete exhibits significant change in the ratio of calcium/sodiu m exchange capacity, due to the release of calcium ions from the concrete material. Also, some decreases in swelling capacity in the backfill material near the concrete-backfill interface were noted.


We have studied the nonlinear dynamics of whistler waves in magnetized plasmas. Since plasmas and beam-plasma systems considered here are assumed to be weakly collisional, the point of reference for the analysis performed in the present paper is the system of hydrodynamic and field equations. We have applied the renormalization group method to obtain dynamical equations for the slowly varying amplitudes of whistler waves. Further, it has been shown that the amplitudes of eigenmodes satisfy an infinite system of coupled nonlinear Schrödinger equations. In this sense, the whistler eigenmodes form a sort of a gas of interacting quasiparticles, while the slowly varying amplitudes can be considered as dynamical variables heralding the relevant information about the system. An important feature of our description is that whistler waves do not perturb the initial uniform density of plasma electrons. The plasma response to the induced whistler waves consists in velocity redistribution which follows exactly the behaviour of the whistlers. In addition, selection rules governing the nonlinear mode coupling have been derived, which represent another interesting peculiarity of our description.

ABSTRACT A driver's muscle activation of lower extremity at a collision moment (ACOL) was precisely described and the influence on injury was investigated. A simulated collision scene was constructed and 10 young male volunteers were recruited for the field test. ACOL of eight major lower extremity muscles were measured. The injury in this muscle activation state was analysed through a simulation and compared with those in minimum, median and maximum activation states. ACOL at 4.1%–22.6% were significantly smaller than fully activated with 100%. Compared with the minimum state, the injury parameters in maximum muscle activation state increased for at least 45%. Muscles are not always in maximum or even median activation at a collision moment. With the increase of muscle activation, the injury will potentially increase and the peak moment of injury parameters will delay. Therefore, muscle activation should be considered in injury analysis and the passive vehicle safety system design.


We analyze pre-explosion near- and mid-infrared (IR) imaging of the site of SN 2023ixf in the nearby spiral galaxy M101 and characterize the candidate progenitor star. The star displays compelling evidence of variability with a possible period of ≈1000 days and an amplitude of Δm ≈ 0.6 mag in extensive monitoring with the Spitzer Space Telescope since 2004, likely indicative of radial pulsations. Variability consistent with this period is also seen in the near-IR J and K s bands between 2010 and 2023, up to just 10 days before the explosion. Beyond the periodic variability, we do not find evidence for any IR-bright pre-supernova outbursts in this time period. The IR brightness ( MKs=−10.7 mag) and color (J − K s = 1.6 mag) of the star suggest a luminous and dusty red supergiant. Modeling of the phase-averaged spectral energy distribution (SED) yields constraints on the stellar temperature ( Teff=3500−1400+800 K) and luminosity ( logL/L⊙=5.1±0.2 ). This places the candidate among the most luminous Type II supernova progenitors with direct imaging constraints, with the caveat that many of these rely only on optical measurements. Comparison with stellar evolution models gives an initial mass of M init = 17 ± 4 M ⊙. We estimate the pre-supernova mass-loss rate of the star between 3 and 19 yr before explosion from the SED modeling at Ṁ≈3×10−5 to 3 × 10−4 M ⊙ yr−1 for an assumed wind velocity of v w = 10 km s−1, perhaps pointing to enhanced mass loss in a pulsation-driven wind.

Three case-sketches published in 1999 by the president of many years of an international psychotherapeutic association are cited, which clearly result in a blaming of victims: of a girl, younger than ten years, sexually abused by its father; of a boy displaced in a Nazi-KZ; of a patient sexually abused by her therapist and thus driven into suicide. The historical source of such a model of therapy is traced out, current difficulties of debating this subject among experts are described. An open, critical discussion of problematic models of psychotherapy beyond the borders of single psychotherapeutic schools, the development of some sort of basic rules for psychotherapy is suggested.

As in other global studies, /sub 137/Cs was found in the highest concentrations in edible flesh of all species of fish and in the lowest concentrations in the bone or liver. The mean concentration of /sup 137/Cs in muscle of reef fish from the southern part of the atoll is comparable to the global-fallout concentration measured in market samples of fish collected from Chicago, IL, USA, in 1982. Strontium-90 is associated generally with non-edible parts of fish, such as bone or viscera. Twenty-five to fifty percent of the total body burden of /sub 60/Co is accumulated in the muscle tissue; the remainder is distributed among the liver, skin, and viscera. The mean concentration of /sub 60/Co in fish has been decreasing at a rate faster than radiological decay alone. Most striking is the range of /sup 207/Bi concentrations among different species of fish collected at the same time and place. Highest concentrations of /sup 207/Bi were consistently detected in the muscle and other tissues of goatfish and some of the pelagic lagoon fish. In other reef fish, such as mullet, surgeonfish, and parrotfish, /sub 207/Bi was usually below detection limits by gamma spectrometry. Over 70% of the whole-body activity ofmore » /sup 207/Bi in goatfish is associated with the muscle tissue, whereas less than 5% is found in the muscle of mullet and surgeonfish. Neither /sup 239 +240/Pu nor /sup 241/Am is accumulated significantly in the muscle tissue of any species of fish. Apparently, /sup 238/Pu is in a more readily available form for accumulation by fishes than /sup 239 +240/Pu. Based on a daily ingestion rate of 200 g of fish flesh, dose rates to individuals through the fish-food ingestion pathway are well below current Federal guidelines. 24 refs., 1 fig., 27 tabs« less


Electrohydraulic proportional valve exits zero dead section.If dead section is over big,it will bring lag effect when handle operate,and affects stability and dynamic characteristic of the control system in positional closed-loop system.So we should manage to decrease the effects of the dead section in order to attain good performance.At present,there are two methods in common use-precursor current and charged plus method.This paper brings forward another method-linearity compensation method,and uses in PID control system.


Based on CO2 laser of the pulse beam cladding Stellite alloy on K403 substrate,the effect of the peak power,pulse width,pulse frequency and scanning speed on the shape and cladding quality was investigated. The results show that with the peak power,pulse width and pulse frequency increase,or with the scanning speed decrease,the bead width,melting depth and rate dilution increase. The integrated melt interface without hot cracking can be obtained by pulse laser at high peak power.


Water is a crucial resource for development efforts in the Himalayan region. Both large- and small-scale development projects require a variety of hydrologic data for planning implementation. Absence of long-term records and practical difficulties in maintaining data quality lead to high levels of uncertainty in water resource assessments. Additionally, basic unanswered questions about the hydrology of the hill regions limit the development and application of effective watershed management practices. A combined programme of data and report compilation, application of existing hydrologic techniques, and new research initiatives is suggested to reduce the uncertainty associated with hydrologic estimates in the Himalaya.


This paper presents a method for generating quick and accurate background level estimations with corresponding threshold level estimations from a distribution profile of time delay integration (TDI) scanning focal plane array (FPA) detector values. The resulting background and threshold parameters are used to separate target signal contribution from background and noise contributions. This method was developed for use in a real-time multiprocessor based infrared (IR) imaging and signal processing system. The algorithms developed for the system have been designed and tested for detection of small targets. This process for estimating background and threshold parameters is explained along with discussions of performance evaluations and limitations.


This essay looks in detail at an unfinished cycle of Holocaust poems called The Black Book that was begun by the American poet John Berryman in 1948. The essay includes close readings of three published poems and analysis of unpublished material from the Berryman archive. It also considers Berryman's use of Holocaust testimony. Drawing on Susan Gubar's concept of 'proxy-witnessing', this essay argues that Berryman's unfinished cycle highlights some of the distinct challenges of Holocaust representation, occupying an uneasy middle ground between language and silence.

The present goal of this study is to analyze the overtraining syndrome's definition, sign, symptom, etiology, prevention, and treatment with physical training and also, we analyzed the practical approaches between overtraining syndrome and immunosuppression in athletes. Overtraining syndrome is described as a form of chronic fatigue, burnout and staleness, and it is also defined as an imbalance between physical training versus recovery. It appears to be imposed by the total amount of physical, psychological and immunological stress in club sports people and athletes. Athletes undergoing a strenuous training schedule can develop a significant decrease in physical performance associated with overtraining syndrome. It is also related with adaptation to physical performance, psychological impairment, and even immunological dysfunction. Generally, one of the well found outcomes of overtraining syndrome is an immunological dysfunction which becomes apparent through an augmented colds. Thus, overtraining syndrome is more than a simple physiological syndrome, it includes mental and emotional factors as well. It might have strongly damaging effects on an athlete's career and it's prevention is of most importance. Therefore, through this paper, we want to analyze the etiology and symptoms of overtraining syndrome with immune suppressions and moreover, we want to provide the many experimentally scientific material to athletes, coaches, and researchers in this fields. Therefore, we want to present definition, etiology, symptoms, mechanism, treatment of OTS, and immunological aspects of OTS, And also we discuss about the experimental approaches to OTS in the final section.


WASTING FOOD IS RUBBISH: BARRIERS AND OPPORTUNITIES FOR FOOD WASTE DIVERSION IN GUELPH, ONTARIO Alexis Van Bemmel Advisor: University of Guelph, 2016 Dr. Kate Parizeau Food waste is a serious global issue that has significant environmental, economic, and social impacts. While increasing attention is being paid to this problem, little region specific research exists on food waste in Canada, and Southwestern Ontario in specific. This research investigates the flow of food waste along the food waste hierarchy in Guelph, ON in order to identify barriers, motivations, and opportunities to increase food waste diversion. 33 respondents along the food value chain participated in semi-structured interviews to provide insight for this research. An actor-network approach was employed to examine the socio-material aspects of food waste and the paths it takes, which revealed that many of the findings relate to the materiality of food/waste. This research contributes to a greater understanding of how we relate to both food and waste systems, and provides recommendations for food waste solutions across


Background Acute kidney injury (AKI) is a well-known complication following a transcatheter aortic valve replacement (TAVR) and is associated with higher morbidity and mortality. Objective We aim to compare the risk of developing AKI after transfemoral (TF), transapical (TA), and transaortic (TAo) approaches following TAVR. Methods We searched Medline and EMBASE databases from January 2009 to January 2021. We included studies that evaluated the risk of AKI based on different TAVR approaches. After extracting each study's data, we calculated the risk ratio and 95% confidence intervals using RevMan software 5.4. Publication bias was assessed by the forest plot. Results Thirty-six (36) studies, consisting of 70,406 patients undergoing TAVR were included. Thirty-five studies compared TF to TA, and only seven investigations compared TF to TAo. AKI was documented in 4,857 out of 50,395 (9.6%) patients that underwent TF TAVR compared to 3,155 out of 19,721 (16%) patients who underwent TA-TAVR, with a risk ratio of 0.49 (95% CI, 0.36–0.66; p < 0.00001). Likewise, 273 patients developed AKI out of the 1,840 patients (14.8%) that underwent TF-TAVR in contrast to 67 patients out of the 421 patients (15.9%) that underwent TAo-TAVR, with a risk ratio of 0.51 (95% CI, 0.27–0.98; p = 0.04). There was no significant risk when we compared TA to TAo approaches, with a risk ratio of 0.89 (95% CI, 0.29–2.75; p = 0.84). Conclusion The risk of post-TAVR AKI is significantly lower in patients who underwent TF-TAVR than those who underwent TA-TAVR or TAo-TAVR.


Thank you for reading data abstraction and program design from object based to object oriented programming. As you may know, people have search hundreds times for their favorite readings like this data abstraction and program design from object based to object oriented programming, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some harmful virus inside their computer.


This paper is concerned with networked output feedback H∞ control of an offshore structure under earthquakes. With a networked model of the offshore structure, a networked output feedback H∞ control strategy is proposed to suppress seismic vibration of the structure. Then, some delay-dependent stability criteria for the offshore structure system are derived. Simulation results show that compared with traditional network-free controllers, the networked output feedback H∞ controller can mitigate vibration of the offshore structure and control cost to a smaller level.


This paper presents a catchment‐scale investigation of anabranching in the moderately large 143 000 km2 Fitzroy River catchment in north‐eastern Australia. The primary aim is to determine whether mapped and remotely sensed data can provide useful information about the characteristics of anabranching in a catchment of this scale. Anabranching comprises 6% of the total channel network by length, and 24% of higher‐order channels (those with catchment areas over 100 km2). Three anabranching planform morphologies are described, which occur in geographically distinct regions, and add to previous descriptions of anabranching rivers. Sinuosity and link length are calculated for all channels of the mapped channel network (a link is a stretch of river between two stream junctions). Slope, mean floodplain width, mean annual rainfall and underlying and catchment geology parameters are calculated for links of a stream network derived from a digital elevation model (DEM), in which each link has either a single channel or anabranching morphology. Anabranching and single channel links do not occupy different ranges of attribute values, and a logistic regression analysis was unable to predict anabranching. However, slope, catchment area, mean floodplain width, length and sinuosity parameters all have significantly different means when comparing single channel with anabranching links, although it is shown that the difference in mean floodplain widths is the result of its correlation with catchment area. Anabranching channels have a tendency towards shorter link lengths, lower sinuosities and lower valley slopes and occur at larger catchment areas than single channels. These differences are discussed in the context of published hypotheses regarding the cause of anabranching. However, the spatial resolution and precision of our data limit our ability to investigate controls on anabranching, which will require detailed measurement of variables at a reach scale.

This study examined the diversity and financial performance of the board of directors of Nigerian citation companies. The purpose of this study is to examine the relationship between board diversity variables and the financial performance of Nigeria's cited manufacturers. The board diversity variables used were board independence, board gender diversity, and board size, financial performance was measured by after-tax profit, and company size was a control variable. Was included as. The study extracted data from the financial statements of 10 Nigerian citations. The data were analyzed using post-hoc estimation tests such as the restricted F-test and Hausmann test, as well as correlation and panel regression analysis including random effects, fixed effects, and pooled OLS. As a result, board independence, board gender diversity, and board size have a positive impact on the after-tax profits of selected listed companies in Nigeria, but with little impact. Became clear. Therefore, the study concluded that there is a slight positive link between the diversity of the Nigerian board of directors and the financial performance of listed companies. Therefore, the level of diversity of the board of directors of Nigerian citation companies needs to be improved. This can improve the decision-making process needed to maintain financial performance.


Aim To investigate the relationship between the levels of nitric oxide(NO) and its inducible synthase(iNOS) in sera and joint fluids of patients with osteoarthritis (OA) and the activity of the disease.Methods The levels of NO, iNOS, erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) in sera and joint fluids of 30 patients with mild, moderate or severe OA respectively and 24 healthy volunteers were measured.Results ① The levels of NO and iNOS in sera and joint fluids of patients with moderate and severe OA were higher than that of normal controls(P0.01).② In comparison with that of normal controls,the levels of NO and iNOS in joint fluids of all patients with OA increased significantly (P0.001).③ The levels of NO and iNOS in joint fluids of patients with severe OA correlated positively with that in sera(r=0.589, P0.01).④ The levels of NO and iNOS in joint fluids of patients with moderate and severe OA correlated positively with the levels of serum ESR and CRP(r=0.428, P0.05).Conclusion iNOS and iNOS-derived NO may mediate the pathogenesis and development of OA.


A chloride-binding capacity is the major factor to mitigate the ingress of chloride into concrete. This paper presents the chloride-binding capacity of Portland cement paste containing synthesized CA2 (CaO·2Al2O3). The CA2 was synthesized in the high-temperature furnace and characterized by X-ray diffraction for inspecting the purity. The synthesized CA2 was substituted for Portland cement by 0%, 5%, and 10% by weight, and the NaCl solution was used as an internal chloride, which is assumed as a total chloride. The chloride-binding capacity of cement paste was calculated from a water-soluble chloride extraction method by the application of the Langmuir isotherm equation. And the hydration products were analyzed using X-ray diffraction and thermogravimetric analysis. We demonstrate that the CA2 increases an AFm phase in the Portland cement system, and the incorporation of CA2 consequently enhances the chloride-binding capacity of cement paste samples.


GM(1,1) model is the kernel of grey system theory, and it is applied widely in practice. This paper presents a two-stage optimization scheme of grey model. An improved GM(1,1) model can achieve much better results than the conventional one in forecast. This model works well in traffic volume prediction. Prediction accuracy and practicability can be further improved by the use of equal dimension recurrence in GM (1,1) model.


Objective To discuss the clinical outcomes of old fracture-dislocation of proximal interphalangeal joint treated with a self-made distraction external fixator which consists of 3 pins and rubbers.Methods From March 2005 to August 2011,8 cases of old fracture-dislocation of proximal interphalangeal joint treated with a pins-rubber distraction external fixator were retrospectively reviewed.There were 6 males and 2 females,aged from 17 to 58 years,averaged 23.2 years.The middle finger was involved in 5 cases and ring finger was involved in 3 cases.The right hand was affected in six patients,and the left hand was affectd in two patients.The mechanism of injury was sports injury in 6 cases,traffic injuries in 1,and sprain in 1.All of the cases were closed injury.The mean time from injury to surgery was 58 d (range,45-90 d).According to Schenck classification of the proximal interphalangeal joint fracture-dislocation,there were 4 cases of type Ⅰ,3 of type Ⅱ,I of type Ⅲ.Based on the Michigan Hand Outcomes Questionnaire (MHQ) for subjective hand function score,the average preoperative score was 56; the range of motion of proximal interphalangeal joint was 0°.Grip strength was 60%-80% of the contralateral hand.Results The follow-up lasted 6-51 months,with a mean period of 20.5 months.Solid bone healing was eventually achieved in all patients.The average healing period was 3 months (range,2-5 months).The mean normalized MHQ score was 88 (range,84-92).Grip strength was 85%-100% of the contralateral hand.Extension of proximal interphalangeal joint was -10°-0° (average,-5°).Flexion angle was 75°-100° (average,89.4°).Postoperative complications included slight joint space narrowing (2 cases),joint incongruity (< 1 mm) (2 cases) and fusiform arthrocele (2 cases).No infection,pin loosening,and pin breakage was encounted.Conclusion A pins-rubber distraction external fixator is a minimally invasive,reliable and effective treatment for old fracture-dislocation of proximal interphalangeal joint.

Background: Visceral leishmaniasis is a major public health concern in Nepal. During the last few years, several Kala-azar outbreaks have been reported from Terai region including Morang district, Nepal.
Objectives: The aim of this study is to determine the risk factors associated with Kala-azar at individual and household levels in selected highly endemic areas of Morang district of eastern Nepal.
Methodology: A case control study was conducted in five endemic village development committees of Morang district with 62 cases already treated from B.P. Koirala Institute of Health Sciences and Koshi Zonal Hospital. Two hundred and forty eight controls were selected randomly from the same village at the ratio of 1:4. Data was collected between September and November 2013 using structured questionnaires. Bivariate and multivariate analysis were done and the final model was selected using the backward elimination strategy.
Results: This study showed that the majority of cases (29.0%) were from the 13-25 years age group, males are more than females and indigenous caste (74.2%) were affected more than other caste. Living in thatched house (OR 4.57, 95% CI 1.91-10.93), ownership of animal (OR 3.95, 95% CI 1.87-8.37), sleeping on the ground floor (OR 3.90, 95% CI 1.83-8.31),  history of migration to India and proximity to other Kala-azar cases within 50 metres distance of household were significant risk factors for visceral leishmaniasis. The association with socioeconomic status remained significant and there was a clear dose – response effect.
Conclusion: Living in thatched house, ownership of animals, sleeping on the ground floor, history of migration to India, proximity to other Kala-azar cases within 50 metres distance and poverty are the main risk factors associated with visceral leishmaniasis transmission.


This study assesses and systematizes the signs of asthenovegetative syndrome (AVS) in patients who had COVID-19 a month ago. The survey was completed by 44 respondents aged 20 to 80 years. According to the results of the survey, the most common manifestation of asthenovegetative syndrome is weakness. The respondents also noted emotional disturbances, decreased attention, sleep disturbances, pain in the joints and muscles, weight loss, and headache. To assess the dynamics of the studied manifestations, a survey was conducted using the Vein's autonomic dysfunction scale. In 93.1 % of the respondents, the total score exceeded 15, which indicates the presence of autonomic dysfunction. The results demonstrate that among patients who have undergone COVID-19, the frequency of autonomic dysfunction is quite high. The manifestations which patients are most often concerned about are asthenic and psycho-emotional disorders. These consequences of COVID-19 significantly reduce the quality of life, which indicates the need for timely diagnosis and provision of qualified care to patients.


The 1970s experienced dramatic increases in the number of part-time faculty employed in higher education. More active adversarial responses have been heard from part-time faculty regarding treatment of their employment interests. This paper notes major statutes, court decisions, and labor board rulings applicable to part-time faculty employment. The issues of legal status, compensation, and unit determination status in collective bargaining are discussed. Administrative parameters for the establishment of reasonable policy guidelines are presented.


The next generation internet protocol version 6 was developed by the network working group of the Internet Engineering Task Force (IETF), to extend and eventually replace IPv4 capabilities and brings many new features over IPv4 like large address space, flow labelling capabilities, expended address capabilities, demand for real time data transfer, security at IP level and so on. However there are various vulnerabilities reported in contrast to the new features emerging in IPv6. One of the kinds of these vulnerabilities exists in routing header of IPv6. Routing header is a kind of extension header of IPv6 and it's used by an IPv6 source to list one or more intermediate nodes to be visited on the way to a packet destination. But routing header has serious vulnerability and by using this vulnerability attacker can by-pass the security principles at packet filtering system such as router/firewall without breaking the packet filtering rules and than he can access the internal protected network by using routing header. This paper suggests a prevention algorithm that uses with existed packet filtering system and solves the vulnerabilities caused by routing header.


Semiempirical models describing the curve for boiling of a liquid on surfaces having porous coatings are proposed. The effect of the main operating and design parameters on the shape and the arrangement of the boiling curves is analyzed. The specific features for boiling water on a surface having a porous coating with channels for the discharge of steam are considered.


SUMMARYThe pollen content of 530 honeys from Galicia (north-west Spain) were analysed. Here, we report the results for the 212 honeys classified as unifloral (83 sweet chestnut honeys, 60 eucalypt honeys, 49 blackberry-type (Rubus) honeys, 12 heather honeys and eight Fabaceae honeys). Galician sweet chestnut honeys are mainly produced in the region's interior, in the provinces of Lugo and Ourense, and can be distinguished from other sweet chestnut honeys by the absence of pollen of mediterranean species (such as Lavandula stoechas, Cistus ladanifer, Olea europaea and Citrus spp.). Galician eucalypt (Eucalyptus globulus) honeys are produced in coastal areas, and can be distinguished from other eucalypt honeys by their low pollen content and the absence of pollen of mediterranean species. Blackberry-type honeys are produced in southern and central Lugo province, and can be distinguished from other Spanish blackberry-type honeys by the absence of pollen of Hedysarum coronarium and Diplotaxis erucoides.

ABSTRACT Regional input–output tables and trade flows: an integrated and interregional non-survey approach. Regional Studies. Regional analyses require detailed and accurate information about dynamics happening within and between regional economies. However, regional input–output tables and trade flows are rarely observed and they must be estimated using up-to-date information. Common estimation approaches vary widely but consider tables and flows independently. By using commonly used economic assumptions and available economic information, this paper presents a method that integrates the estimation of regional input–output tables and trade flows across regions. Examples of the method implementation are presented and compared with other approaches, suggesting that the integrated approach provides advantages in terms of estimation accuracy and analytical capabilities.


CLEVELAND -- Milo and the Green Wagon, a Life Lesson to Give is an endearing tale based on a true story drawn from the writer's own childhood. Similar to an experience Lisa shared as a youngster with her brother David, Milo and his friends find an old, discarded green wagon and decide to fix it up and use it to collect food and clothing for those in need. Lisa's heartwarming story teaches children about generosity, selflessness and, most importantly, about love and respect for all people, no matter what their stature in life. As you read through Milo's journey with your child, he or she will learn what it means to donate and will realize the good that comes from a mission such as Milo's, a mission he calls: ACT – Action Changes Things. Umina's clever words and expressions will entice you right up until the very end when Milo and his friends' compassion is rewarded with a surprise Visitor at Sunday service; a Visitor that makes all of their acts of kindness well worth the effort. Lisa Umina, owner of Halo Publishing International, not only publishes books but also enjoys a successful


A first-principles based multiscale modeling approach to heterogeneous catalysis is presented, that integrates first-principles kinetic Monte Carlo simulations of the surface reaction chemistry into a fluid dynamical treatment of the macro-scale transport in the reactor. Using the CO oxidation at RuO2(110) as representative example the relevance of first-principles kinetic Monte Carlo is demonstrated by the comparison with the commonly employed, but less accurate rate equation based approach to surface chemistry. Huge differences between both approaches in the predicted reactivity and qualitatively wrong predictions on the ongoing surface dynamics disqualify the latter approach for the use with first principles input. An efficient general purpose methodology is developed, which allows for simulations of macroscopic catalytic reactors with the same speed as mentioned empirical approaches, but retains the sound electronic basis and the accurate treatment of surface chemistry by kinetic Monte Carlo simulations. As a simple showcase the developed method is applied to stagnation flow fields in front of a RuO2(110) single crystal surface. The simulation results show how heat and mass transfer effects can readily affect the observed catalytic function at gas-phase conditions typical for modern in situ experiments. For a range of gas-phase conditions we furthermore obtain multiple steady-states that arise solely from the coupling of gas-phase transport and surface kinetics. This additional complexity needs to be accounted for when aiming to use dedicated in situ experiments to establish an atomic-scale understanding of the function of heterogeneous catalysts at technologically relevant gas-phase conditions.


Ferroresonance is complicated nonlinear phenomenon which often happens in power system.Core loss of the power transformer is modeled by a third order series in voltage.Comparing with linear core loss,the results show that the onset of chaos appears at larger excitation voltage and the transient duration is shorter.Moreover,the EMTP simulation results show the rightness of theory analysis.


DNS method was adopted to systematically analyse the effect of different reaction conditions on crude pectinase liquid which fermented by a highly efficiently degumming strain CXJZU95-198.The results showed that reaction conditions affected test results of pectinase activity.Among these conditions,the temperature,type of buffer,type of pectine and pectine concentration played more important roles while the pH of buffer and DTT concentration played less important roles in pectinase activity testing.The optimum conditions of pectinase activity reaction run as follow: temperature 50℃,concentration of pectine from citrus fruits(SIGMA) 0.2%,pH 5.2(1/15mol·L-1KH2PO4-Na2HPO4 buffer),1.0mmol·L-1DTT.


The magnetic reconnection mechanism is a primary candidate for "flare" processes in solar coronal regions. Numerical simulations of two-dimensional magnetic reconnection are carried out for four different cases: (1) adiabatic condition with constant resistivity, (2) adiabatic condition with temperature-dependent resistivity, (3) energetics with radiation loss and constant resistivity and (4) energetics with radiation loss and temperature-dependent resistivity. It is found that the thermal instability prompts the magnetic reconnection process, thus increasing the conversion rate of magnetic energy into kinematic energy of the fluid. We demonstrated that the observed microflares can be accounted for by our magnetic reconnection models, when the effects of the radiation loss and the temperature-dependent resistivity are taken into account.


When I read the call for papers for this special issue of Performance Matters, I was struck by the phrase "We approach the back in multiple senses." Why, I wondered, is the back here construed as a passive surface, a sleeping creature on which we researchers do the sneaking up? By enacting what I call a "cheeky reversal," this essay aims not to "approach the back in multiple senses" so much as to investigate the many senses in which backs and buttocks do the approaching.


Regulations for Supply Security and in Emergency Situations Before and After the Lisbon Treaty Entry into Force Exemplified by Supply with Natural GasThe text presents selected aspects of the issue of the provision of energy supplies security in the European Union illustrated by the example gas supply before and after the entry into force of the Lisbon Treaty. The legal frameworks oriented toward provision of gas supplies security as well as proper functioning of internal market gas in case of disruptions in gas supplies in the European Community/European Union has been discussed in the text. Among the legal acts described in the text are: Council Directive 2004/67/EC of 26 April 2004, Regulation (EU) No 994/2010 of the European Parliament and of the Council of 20 October 2010, Regulation (EU) 2017/1938 of the European Parliament and of the Council of 25 October 2017. In order to provide energy supplies security in case of disruptions in supplies the secondary legislation enhances capabilities of transport, storage and reacting.


We define the notions of ^-primarity and of ^-connectedness, as well as an analog of monomial U-rank, namely Frattini-free. We then derive some results concerning the Frattini-free component. In particular, the Frattini-free component of a semisimple stable group is the direct product of ^-connected groups, and the Frattini-free component of a soluble Sft-group has nilpotent derivative. Finally, the radical of the Frattini-free component of a definable 9ΐ-group is definable.


Abstract A methodological framework of land resource assessment, based on integrated biophysical information of the land in GIS and remote sensing is presented. The model developed uses two primary sub‐models (modules): remote sensing based land use classification, and land suitability assessment. The first module uses Landsat 7 ETM+ images to produce a land use/land cover map of the study area. A site‐specific framework was developed for use in thematic information extraction involving the use of visual analysis, spectral‐based (automated) procedures, and ancillary information. The second sub‐model implements a fuzzy set methodology, and uses soil landscape data sets and a Digital Elevation Model as evaluation criteria. The databases used were all georeferenced and standardised in a GIS format, enabling spatial analyses for possible pairings of data sets to be performed in order to derive new information sub‐sets. A test case is presented to map the spatial distribution of runoff Curve Number (CN) using soil landscape data, which were also used for land suitability evaluation, along with existing land use/land cover information. The strategies and analytical procedures developed in this research may be useful in other areas, particularly in projects related to mapping biophysical resources for sustainable land use planning and management.

This chapter develops a theoretical model for understanding 'ontological precarity' among older workers. Ontological precarity is caused by individuals feeling 'trapped' between precariousness in different domains of their lives. Individuals worry about the long-term sustainability of their 'precarious employment'. This anxiety is enhanced by financial pressures to work longer in the context of diminishing financial support from a 'precarious welfare state' and from 'precarious households'. The chapter presents case studies of three older hospitality workers, in order to illustrate how these different forms of precarity interact. It concludes by discussing policy implications and provides suggestions for how the framework could be used in future research.


This paper describes the community initiative undertaken in Kiambiu slum settlement in Nairobi, which like many other slums, has been without proper water and sanitation since its coming into being as early as 1950s. Following a participatory workshop held in 1999, the residents of Kiambiu under community based group "Kiambiu Usafi Group" (KUG) identified and prioritized their immediate needs as Water, Sanitation (Toilets) and Access (Roads). Together with Maji na Ufanisi (Water and Sanitation), a NonGovernmentOrganization (NGO), they started the Water, Environment and Sanitation (WES) initiative as a collaborative effort between the community and Maji na Ufanisi. The main focus of the collaboration was to support the community initiative of provision of safe water and better sanitation for cleaner environment. The paper explains how the KUG members developed capacity and organized themselves to undertake the management of the water and sanitation facilities that were developed through the support of Maji na Ufanisi. The paper demonstrates in its discussion how water and sanitation initiatives in slum settlements can be undertaken by the government and other development partners to create healthy and live-able environments for the slum dwellers. The information presented in this paper was gathered through, review of technical information from the Maji na Ufanisi, interviews, group discussions and observations.


Summary Photorespiration is essential for C3 plants, enabling oxygenic photosynthesis through the scavenging of 2‐phosphoglycolate. Previous studies have demonstrated that overexpression of the L‐ and H‐proteins of the photorespiratory glycine cleavage system results in an increase in photosynthesis and growth in Arabidopsis thaliana. Here, we present evidence that under controlled environment conditions an increase in biomass is evident in tobacco plants overexpressing the H‐protein. Importantly, the work in this paper provides a clear demonstration of the potential of this manipulation in tobacco grown in field conditions, in two separate seasons. We also demonstrate the importance of targeted overexpression of the H‐protein using the leaf‐specific promoter ST‐LS1. Although increases in the H‐protein driven by this promoter have a positive impact on biomass, higher levels of overexpression of this protein driven by the constitutive CaMV 35S promoter result in a reduction in the growth of the plants. Furthermore in these constitutive overexpressor plants, carbon allocation between soluble carbohydrates and starch is altered, as is the protein lipoylation of the enzymes pyruvate dehydrogenase and alpha‐ketoglutarate complexes. Our data provide a clear demonstration of the positive effects of overexpression of the H‐protein to improve yield under field conditions.


The objective of this work is to analyze LOS for patients admitted to the ophthalmology department. The procedures that are performed in this department are many, but our job is to focus attention on retinal diseases. Postoperative time and timely diagnosis are essential for proper patient care. A prolonged length of stay (LOS) average hospital can not only have negative effects on the patient's quality of life but has The LOS is one the main factors affecting on the effectiveness of national health system, which is influence by different contextual information (i.e., inadequate resource management, bed availability and surgical interventions). It is interesting and important to analyze the Length of Stay (LOS) and to implement models that allow to predict such indicator. LOS is related to several variables that describe the patient's condition that affect the management of resources, beds, and the entire department. In this work, we design different Machine Learning models with the aim to predict the LOS. In particular, we evaluate the effectiveness of our approach by analyzing information about 450 patients frmo the University Hospital "Federico II" in Naples (Italy).


This paper is intended to review the development of active power filter (APF) technologies that are commonly used to mitigate harmonics in utility power lines. This review can also be considered as a "tutorial-type paper" as it provides a holistic coverage of the APF technologies by omitting the tedious details, but without losing the main essence of the subject matter. It is hoped that by this approach, it would be possible to lure more power engineering readers to be involved in this important and growing field. The discussion starts with a brief overview of harmonic distortion problems and their impacts on electric power quality. The operation of common APF topologies, namely the shunt, series and hybrid APFs are described in detail. This is followed by a review on different types of reference signal estimation extraction techniques. In particular, the application of the p-q and extension p-q theorems to extract the reference signals are elaborated, as they are the most commonly found in practical APF systems. Finally, an overview of the APF control strategies is provided. A brief discussion on the APF-solar photovoltaic system is also given. At the end of the paper, important references are cited to assist readers who are interested to explore the subject in greater detail.


The relative motion of full-function PAN coordinator in a WPAN or WSN leads to a Doppler Shift in the frequency of the signal transmitted towards it. This Doppler Shift has its impact over the Bit Error Rate performance of modulation scheme incorporated in transceiver circuits of sensor nodes. By spreading the encoded stream of data using either FHSS or DSSS, this impact may easily be overcome. This paper is a comparative BER performance analysis of Reed-Solomon coded non-coherent M-ary FSK scheme with Direct Sequence Spread Spectrum. The simulations are run with common and all possible types of spectrum of Doppler Shift defined for both Rayleigh and Rician fading channel conditions using a MATLAB / Simulink model. The simulation results show that, there is an appreciable performance difference between the scheme with DSSS and the scheme without code spreading for channel with Rayleigh fading. However, the difference is not as much as the previous case for the channel with Rician fading.

Objective: In the present research work silver nanoparticles were synthesized using the flower extract of Chrysanthemum coronarium and their in-vitro antibacterial activity was evaluated against both the gram-positive S. aureus and gram-negative bacteria E. coli. The flower extract acted both as a reducing as well as a capping agent.Methods: Silver nanoparticles were verified using various spectroanalytical techniques such as visible ultraviolet spectroscopy, zeta potential, fourier transform infrared spectroscopy and particle size analyser. The antibacterial activity was evaluated against both the gram-positive bacteria S. aureus and gram-negative bacteria E. coli using the agar well diffusion method.Results: The silver nanoparticles synthesized were confirmed by the visual colour change. The ultraviolet, visible spectroscopy showed a surface plasmon resonance at 430 nm. Zetapotential was found to be around-15.6mV where the negative value indicated that the synthesized silver nanoparticles are stable. Fourier transform infrared spectroscopy showed the functional groups responsible for the stabilization of the nanoparticles. Particle size analyser showed that the size of the nanoparticles ranged from 5-50 nm. The antibacterial activity of the silver nanoparticles which was performed against S. aureus and E. coli showed good inhibition against both the bacteria. Better antibacterial activity was found for E. coli in comparison to S. aureus as the zone of inhibition for E. coli was found to be at 12 mm at 50ug/ml whereas the zone of inhibition against S. aureus was found to be at 10 mm.Conclusion: The silver nanoparticles were successfully synthesized using a green approach and can be used as a potential resource for therapeutic purpose.

Development of the automotive world, more and more fuel oil is required to refuel cars. As the price of oil continues to rise, the automotive industry has begun to develop non-petroleum fueled motorcycles, one of which is electric motorcycles. Although it is currently very difficult to completely replace fossil fuels, the introduction of renewable energy sources will be very important to start immediately. One of them is a system to reuse an existing battery charging system on an electric motor in turn, where, when the engine is running, the charging system uses a DC generator located on the electric motor. And when the engine stops, the charging system uses the current source from PLN.


Residents, transportation professionals, and decision-makers throughout the Piedmont Triad generally agree that the prosperity of the region depends on having an adequate transportation system. The ability to move people and goods quickly, efficiently, and safely affects both this region's economy and the quality of life. The purpose of this report is to describe the implementation of Advanced Transportation Systems (ATS) Technologies for the eleven Piedmont Triad Counties. Particular emphasis is being placed on the Interstate 40/ Interstate 85 corridor. Advanced technologies including so-called "smart highway" or IVHS technologies will be utilized in order to help solve the traffic problems in the Triad. IVHS, which stands for "Intelligent Vehicle-Highway Systems" actually is a misnomer because transit systems are also included. Hence, ATS (Advanced Transportation Systems) is the title that has been adopted to describe such transportation improvements in the Triad. ATS (or IVHS) means using advanced technology to improve traffic flow on highways without necessarily adding more lanes or roads. In addition, ATS means using advanced technology to provide safer, more efficient transit service.

Deregulation of receptor tyrosine kinases (RTKs) is linked to a broad range of cancers, stressing the necessity of studying their regulatory pathways. We and others demonstrated previously that c‐Cbl is necessary for the lysosomal degradation of erythropoietin‐producing hepatocellular B1 (EphB1) carcinoma and epidermal growth factor receptor (EGFR) RTKs. Moreover, the tumor suppressor phosphatase and tensin homolog (PTEN) was shown to modulate c‐Cbl‐dependent EGFR degradation. We therefore investigated the involvement of PTEN in EphB1 signaling and degradation. We used PTEN mutants, PTEN, and NHERF1 small interfering RNA in CHO‐EphB1 and SW480 cells endogenously expressing EphB1 to delineate EphB1‐PTEN interactions. PTEN was constitutively associated with c‐Cbl, protecting it from degradation. EphB1 stimulation triggered ~50% serine‐threonine PTEN dephosphorylation and PTEN‐Cbl complex disruption, a process requiring PTEN protein phosphatase activity. Both proteins independently translocated to EphB1, with PTEN in association with the scaffold protein NHERF1. Biologically, PTEN lipid phosphatase activity impairs EphB1‐dependent cell adhesion and chemotaxis. This study demonstrates for the first time in mammalian cells that the Eph receptor and PTEN associate and influence their signaling. Moreover, it contributes to the emerging concept that PTEN regulates expression of RTKs through modulation of their degradation. Finally, it reveals a new role for PTEN protein phosphatase activity involved in this process.—Rodriguez, S., Huynh‐Do, U. Phosphatase and tensin homolog regulates stability and activity of EphB1 receptor. FASEB J. 27, 632–644 (2013). www.fasebj.org


The research is aimed at describing the use of metaphors and finding out its implications in the song lyrics of Ebiet G. Ade from the album of Perjalanan to semantic learning of Indonesian language. The research uses analytical descriptive method with structuralism and propositional approaches. The technique of data collection is done by using note taking. The data of metaphor is analyzed using content analysis. The result shows that the album of Perjalanan from Ebiet G. Ade, consisting of nine songs, has 40 metaphors used to describe the thought and meaning about love among humans and their life covering happiness, sadness, and imagination. The use of metaphors is also to describe humans, life, feelings, suffering, sadness, and anxiety. Metaphors are also used for describing natural phenomena, society's life, social relations among humans and the description of the world. The description of humans and God relationship is also there, using complex metaphors. The analysis of metaphors use in the song lyrics of Ebiet in the album of Perjalanan can improve students' vocabulary enrichment and its meaning. Hence there is an implication to semantic learning of Indonesian language.


A virtual listening environment providing localization cues is proposed for the reproduction of acoustic depth. By simulating the propagation of acoustic waves inside a tube it allows to change the source/listening point positions interactively, in a way that listeners experience various spatial configurations depending on the source/listener mutual position, and, correspondingly, perceive different auditory cues of depth. The quantitative relationship existing between physical and auditory distance assessments suggests to represent the tube using a model which allows direct control of the depth parameter. Simulations and experiments demonstrate the effectiveness of the model and its relative robustness in applications contexts where state of the art equipment and ideal listening conditions cannot be guaranteed.


We are in the midst of a global pandemic. As of this writing, since December 2019, more than three million people have been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 233,000 have died of coronavirus disease (COVID-19), and millions of others have lost their jobs and their sources of income. The pandemic has created a worldwide financial crisis and has brought the critical role of public health to the forefront: among public officials, in media, popular culture, and our daily lives. We, the editorial team of Health Education & Behavior, believe the epidemic has revealed the fragmentation of our public health strategies. We have seen effective measures at work and their costs: financial strain, food insecurity, intimate partner violence, and poor mental health. We have witnessed incompetence and deep fault lines, as well as the weight of existing social inequities. We are interrupting our regular Journal issue to address, within our scope and resources, the COVID-19 pandemic. We want to reflect on the response of our field, the lessons we have learned, and on how it may shape the future of public health. In this issue, we bring together a collection of papers tackling various aspects of the pandemic. We selected these articles from a special call announced in March of this year. The COVID-19 pandemic is in our collective consciousness; this, as much as its physical impact, is what makes it global. We are still uncovering its force and consequences and do not know the full effect it is having on our lives, including the lives of those largely unsung essential workers—for example, in warehouses, meat plants, sanitation, energy and utilities, supermarkets, mass transit, and maintenance—who may have no choice other than to work. If there is a little to praise and be grateful for right now, it is the tremendous talent of health care workers, health educators, and those public health officials who put the collective well-being before their own. There is something disturbing (to say the least) in the way governments have reacted to this threat. There is definitely an urgency in providing answers because it is disproportionately killing the most vulnerable groups (e.g., racial minorities, the poor, older adults) and it is taking the lives of our parents and grandparents. The concern is the rush toward biomedical research on COVID-19, without an equal attention to the social determinants of health (or those factors that could prevent pandemics from occurring or, at least, lessen their impact). The crisis is revealing the harm done by years of defunding of public health infrastructure (even in the era of Affordable Care Act). This is palpable, for example, in the shortage of nurses, physicians, testing, and hospital equipment and in the absence of a consistent and concerted strategy for containment efforts and trustworthy communication. Localities are poorly equipped to confront this pandemic: a capacity difficult to build up in the middle of the storm. With novel viruses for which there is no vaccine or effective medical treatment, biomedical interventions are largely ineffective in reducing their spread in the initial phases of pandemic communicable disease. The most useful public health approaches to slow transmission are social and behavioral in nature. Subsequently, there has been the implementation of policies designed to target people's actions—for example, physical distancing, isolation and quarantining, 935067 HEBXXX10.1177/1090198120935067Health Education & BehaviorRamirez-Valles et al. research-article2020


A field experiment was conducted at the nursery of ornamental plants, Faculty of Agriculture, Minia University during 2018/2019 and 2019/2020 seasons to study the effect of three planting dates (November 1st, November 15th and December1st) and three plant spacings (10, 15 and 20 cm) on growth, yield and chemical composition of quinoa plants to obtain the best agricultural transactions under the conditions of Central Egypt. The results showed significant effects of planting dates on all the studied traits, except for plant height, weight of 1000 seeds and protein% in both seasons, with the planting date of November 15th being the best date. The effect of plant spacing was significant for all studied characters, except for weight of 1000 seeds and protein % in the first season. Planting quinoa seeds at 15 cm. was superior to the other spacings in most cases. The interaction between planting dates and plant spacing between plants was insignificant except for number of panicles/plant and yield of seeds/plant (g) in both seasons and the weight of 1000 seed (g) and seed yield/fed (ton) in the second season. Therefore, it is recommended to cultivate the quinoa on November 15th at a distance of 15 cm apart under the conditions of Central Egypt because it gave the best values for economic characteristics


In order to investigate the effects of top-dressing quantity,time and frequency on growth of Tectona grandis,the manurial experiments with compounded fertilizer(N10-P10-K8),3 factors(top-dressing quantity,time and frequency) and 8 kinds of treatments in the pure forest of 2-year-old of Tectona grandis and mingled forest of Tectona grandis and Erythrophloeum fordii.The results show that the best amounts of top-dressing quantity were 1 000.0 g/tree per year for 3-year-old stand and 2 000.0 g/tree per year for 4-year-old stand;when the top-dressing quantity were lower than these levels,the increments of height and DBH would be increased with the addition of top-dressing quantity,the increments of height and DBH would be reduced when the top-dressing quantity were higher than these levels;the increments of height and DBH when the trees were fertilized in May were better than that in June or July,the increments of them when fertilized for two times were larger than one time,there were different effects of fertilization in different fields,there were no differences in fertilizing effects between pure forest and mingled forest.


This paper examines how expressivism fares against the Frege-Geach problem, which challenges expressivists to explain certain features of our language, namely, what unendorsed sentences with normative words mean, and how such sentences, along with their endorsed counterparts, can figure in valid inferences. I argue that if it is appropriate for expressivism to attempt to solve the Frege-Geach problem by appealing to minimalist theories of truth, then expressivism can indeed solve the Frege-Geach problem with such an appeal, but only at the cost of losing its distinctive features and lapsing into a form of cognitivism, the very position against which it was developed.


This chapter proposes an analysis of Security Council Resolution 2178 (2014) as an illustration of how states used the institutional structure set up by the liberal international legal order in order to provide a comprehensive framework for addressing the mobilization and recruitment of so-called foreign fighters. In the second part of the chapter, two particularly emblematic policies tailored towards addressing 'foreign fighter' mobilization will be analysed. First, against the background of the 'foreign fighter' phenomenon, initiatives to prevent violent extremism and radicalization have gained traction with a particular focus on the abuse of modern information and communication technology to incite support for terrorism and spread violent extremism is highlighted. Second, states increasingly resort to revocation of citizenship as a part of their counterterrorism arsenal.

Background Inter-pregnancy interval (IPI) is the elapse of time between the end of one pregnancy and the conception of another pregnancy, while birth to pregnancy interval, is the time gap between live birth and the conception of the next pregnancy. Hence, this study assessed the effects of short inter-pregnancy intervals on perinatal outcomes among women who gave birth in public health institutions of Assosa zone, North-west Ethiopia. Methods An institution-based prospective cohort study was conducted among 456 mothers who visited health facilities for the fourth antenatal care appointment (152 exposed and 304 non-exposed). Women who gave their recent birth with the pregnancy interval of <24 months or/and had an abortion history of <6 months were considered as exposed otherwise non-exposed. Data was collected through face-to-face interviews by using questionnaires and checklists. The collected data was entered using Epi-data and exported to STATA for analysis. A log-binomial regression model was used to identify the effect of short inter-pregnancy intervals on the perinatal outcomes. Results The overall incidence of adverse perinatal outcomes is 24%. Mothers who had short inter-pregnancy intervals have two times the risk to develop low birth weight (RR: 2.1, 95%CI: 1.16–3.82), and low Apgar score (RR: 2.1, 95%CI: 1.06–2.69). Similarly, the risk to develop small for gestational age (RR: 2.6, 95% CI: 1.19–7.54), and preterm birth (RR: 3.14, 95%CI: 1.05–4.66) was about 3 times among mothers who had short inter-pregnancy interval compared to mothers who had an optimal inter-pregnancy interval. Conclusion Short inter-pregnancy interval increases the risk of low birth weight, preterm birth, small for gestational age, and low Apgar score. Health Policy makers, National health managers and health care providers should work on increasing the awareness of optimal inter-pregnancy intervals and postpartum family planning utilization to reduce the effect of short inter-pregnancy intervals on adverse perinatal outcomes.


According to Professor Replogle our effort to retrieve Macpherson's liberalism is unnecessary and it only serves to expose our own deficiencies.' He claims that we fail to entertain a "historically respectable view" of man, holding instead to a form of "moral licence"; that we hold views that "no sensible critic" would and are unequipped to deal with "a banal fact"; and that we show "disdain" for the concepts that might rescue us. So enfeebled, we turn to the task at hand. In our view, Professor Macpherson's political thought is guided by an ethical principle consisting of two ontologies: a liberal doctrine of self-governance, and a commitment to the development of man's essential humanity. Macpherson sees that the institutions and ethos of capitalist market society violate this principle and accordingly he calls for a social transformation. But in examining his views on social transformation we found that Macpherson's heavy emphasis on the developmental ontology leads too easily to a justification of vanguard rule, thereby putting at risk any system of civil and political rights based on the ontology of self-governance, and exposing the tension between the two ontologies. We further argued that when Macpherson does rely on the developmental ontology rather than the self-governance ontology as a justification for social transformation, he does so because he understands the self-governance ontology to logically entail market society. But we believe that his reliance on the developmental ontology is unnecessary because the self-governance principle is compatible with other forms of social organization, such as socialism, and that market society could be transformed on the basis of the self-governance principle through the mechanism of consent. Thus, we concluded that the choice between liberty and human development is not as stark as it appears in Macpherson's analysis. Replogle claims that Macpherson does not need retrieving because he does not suffer "from the confusions that afflict Seaman and Lewis"


Time-resolved tools for activating proteins of interest in living systems can allow monitoring of the dynamics of biological processes such as signal transduction. Various approaches have been developed to engineer both constitutive and inducible protein activation (e.g. genetic fusion of light switchable proteins). Active-site decaging is another strategy, but the limited number of genetically encoded unnatural amino acids and associated decaging reactions restricts its use to a limited number of protein families. Professor Peng Chen and Professor Chu Wang from the College of Chemistry and Molecular Engineering at Peking University have recently reported a universal protein-activation method in living systems, enabled by computational protein design [1], that they describe as 'proximal decaging'. The Chen lab has previously developed bioorthogonal cleavage reactions to perform gainof-function studies of protein families such as kinases by genetically encoded active-site decaging [2,3]. In collaboration with the Wang group, which has deep expertise in bioinformatics and computational modeling for discovering and manipulating functional sites in proteomes, they sought to introduce a photo-caged tyrosine (ONBY) as a universal 'cage' at a site near, but not in, the catalytic center of the target protein or enzyme. The caged amino acid blocks protein activity but, upon decaging, the protein activity is immediately unleashed, even in a complex proteome (Fig. 1). The strategy goes beyond traditional active-site-based methods by targeting the substrate/cofactor binding pocket and is in principle capable of controlling the function of almost any protein of interest. In order to identify suitable sites for ONBY insertion in an unbiased way, the Wang group employed Rosetta [4] to systematically calculate the impact on protein stability and substrate binding of the introduced tyrosine both with and


Tomato Bushy Stunt Virus (TBSV) was firstly reported on tomatoes by Smith in 1935 in England. The virus belongs to genus Tombusvirus and family Tombusviridae , is a soil-borne virus with isometric particle about 30 nm in diameter. Tomato Bushy Stunt Virus can cause chlorosis, necrosis, stunting, leaf yellowing, leaf mottling, leaf crinkling and fruit setting may be reduced or become zero. These symptoms were depending upon the host morphology. Transmission of this virus is naturally through infected seeds, propagative material and manually by the use of infective cutting tools. A numbers of varieties were affected. But it's also observed that Lycopersicon pimpinellifolium not susceptible host plant. Gel Electropherotic analysis shows that virus distantly related serologically with several other viral species in the genus Tombusvirus . In phosphotungstic acid, the particles show an angular outline and unresolved surface structure but when mounted in uranyl acetate, they exhibit a rounded outline and somewhat knobby surface and edges. The viral genome is monopartite and TBSV-Ch has been completely sequenced and shown to contain 4,776 nucleotides. The protein shell is constructed by 180 subunits, each subunit contain Mr 41,000 and made icosahedral surface lattice. These subunits show a dimeric clustering on the surface of particles, which give rise to 90 morphological units. These were located on the two-fold axes of the lattice. Each coat protein subunit contains 387 amino acid residues and has four regions. Keywords: Tomato Bushy Stunt Virus, Genus Tombusvirus , Family Tombusviridae , Monopartite, Genome analysis of TBSV.


Experimental results obtained on CdS, ZnO, and CdSe are presented which show electron‐beam‐pumped laser emission resulting from the decay of free excitons to photons and longitudinal optical (LO) phonons. Calculations based on available absorption data for ZnO and CdS show that at 77°K the required exciton density for stimulated emission is about 1017 and 1018 cm−3, respectively.


Globalization is an inevitable trend and has been penetrating into every corner of the earth because of the continuous development of social productive force.China's entry into globalization is a passive process.China was bullied by capitalist countries possessing advanced science and technology.We must implement strategies of revitalizing China through science and education in the process of globalization.With the current global environmental problems becoming increasingly prominent,sustainable development is the only wary out for global consensus.So we must implement strategies of revitalizing China through science and education closely combined with road of sustainable development.


The low pressure at high altitudes (above 2500 m) causes hypoxia (decreased oxygen) that affects people's physiological and psychological characteristics. Specifically, hypoxia may affect the neural function of the brain, leading to severe cognitive deficits and a significant decline in memory function and attention. This article addresses the effect of human factors on transportation design and operation at high altitudes (HA), with some details on the Tibet-China region. Specifically, the paper first reviews the basic transportation-related concepts for high altitude, including oxygen and temperature levels, driver perception-reaction time, hazard perception, vehicle speed, and walking speed. Then, the transportation users affected by high altitudes are discussed, including drivers, pedestrians, cyclists, passengers, and others. Next, the impacts of human factors on highway design and operation for HA regions are discussed along with the research needs. Finally, recent innovations to address the challenges of HA transportation are presented, along with case studies comparing some human factors of the plateau and plain areas. This article represents a valuable reference for future research in HA regions to improve transportation design and safety


This paper considers the problem of the flat ring motion of a viscous capillary fluid rotating by inertia. As a result of numerical simulation of a viscous liquid ring oscillations have been detected. We describe the laws of the periodic motion of the considered system.


This paper is a continuation of a series of studies on the thermodynamic parameters of rare-earth tungstates. Measurements on the enthalpies of Dy2WO6 and Dy2(WO4)3 at high temperatures are reported. It is determined that Dy2(WO4)3 shows a reversible phase transition at 1243 K having an endothermic effect; the effective enthalpy of the transformation is about 14.2 kJ/mole. Interpolation equations have been derived for the temperature dependence of the enthalpy and for the average and true specific heats for these compounds.


ISO Technical Report 23173 describes methods by which electron spectroscopies, including X‐ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and synchrotron techniques, can be employed to calculate the coating thicknesses and compositions of nanoparticles. The document has been developed to review and outline the current state‐of‐the‐art for such measurements. Such analyses of core–shell nanoparticles are common within the literature, however the methods employed are varied; the relative advantages and disadvantages of these methods, and the optimal usage of each may not be clear to the general analyst. ISO Technical Report 23173 aims to clarify the methods that are available, describe them in clear terms, exhibit examples of their use, and highlight potential issues users may face. The information provided should allow analysts of electron spectroscopy data to make clear choices regarding the appropriate analysis of electron spectroscopy data from coated nanoparticle systems and provide a basis for understanding and comparing results from different methods and systems.


Patients sitting in a wheelchair may spend hours in a relatively fixed position, with their lower back forced away from its natural lordotic curvature. This prolonged sitting was reported to be linked with low back problems. The aim of this study was to develop a design system that can simulate the kinematic behavior of musculoskeletal forms and generate a human-wheelchair interface to provide accurate means of designing effective seating solutions for wheelchair users preventing long-term spinal deformities. This virtual simulation platform aims to aid clinicians in their analysis to ensure higher degree of accuracy and consistency in the prescriptions.
 LifeMOD#8482; was used as the base simulation software package to build a detailed spine multi-body model. The presented model can be applied to understand the complex spine biomechanics and clinically important analysis such as contact forces between each vertebra and wheelchair model, load acting on the intervertebral disc joints, corresponding angles between vertebrae in the seated position and tension in the spine muscles. These results aid clinicians to develop mechanical design of back support, such as placing conventional pillows and towels at appropriate positions which can be an effective and convenient alternative to expensive special seating.
