Project Objectives Over the summer, I conducted a 400-person follow up  study on the Woebot mental health chatbot to  understand the relationship between user text input and  standard psychological surveys that measure depression  (PHQ-9), anxiety (GAD-7) and therapeutic alliance  (WAI) at three timepoints: a baseline at enrollment, two  weeks later and four weeks later. This research study is  the main component of my senior thesis in Symbolic  Systems and I am currently working on publishing a  paper on the results with therapeutic alliance. My CS  229 project focuses on a different subset of my  research. In this paper, I attempted to predict a user's  severity of depression as defined by the PHQ-9 at the  two week time points using both survey data and user  transcript text data.


Peppermint shrimp resembling Lysmata vittata Stimpson, 1860, a species native to the Indo-West Pacific, were found in the lower Chesapeake Bay and adjacent coastal embayments in 2013, representing the first recorded introduction of this species in the northwestern Atlantic. Conflicting morphological descriptions, inconsistent morphological terminology, and limited molecular data (i.e., unresolved taxonomy), as well as the destruction of the type material of L. vittata , created uncertainty regarding proper identification. We provide the first phylogeny incorporating individuals from across the presumed native and introduced range of L. vittata . Morphological and phylogenetic analyses clearly indicate L. vittata represents a species complex of two widely divergent groups: 1) "Bruce Type" with a uniramous dorsal antennule that agrees with A.J. Bruce's 1990 redescription of L. vittata , and 2) "Rauli Type" with a one-article accessory branch on the dorsal antennule that agrees most closely with the junior synonym L. rauli Laubenheimer & Rhyne, 2010. Given the taxonomic ambiguity surrounding L. vittata , we designate the individual used by A.J. Bruce to redescribe L. vittata and incorporated in our analyses as a neotype to fix the identity of this species. We therefore identify introduced North American and New Zealand populations as L. vittata sensu stricto and postulate that the native range spans temperate/subtropical East Asia. These data suggest that L. rauli is a valid species, which includes a possible undescribed sister species. We confirm the presence of L. californica Stimpson, 1866 in New Zealand, the first non-native record for this species. We also provide data suggesting L. dispar Hayashi, 2007 may be more widespread in the Indo-West Pacific than currently known and consider L. lipkei Okuno & Fiedler, 2010 to be a likely junior synonym.


Al18B4O33 particle and whisker reinforced magnesium alloy (AZ91D and ZK60) composites were fabricated by the compocasting. Some composites were extruded at 400 or injectionmolded after casting. As-cast composites have low strength because of high porosity and large α phase grain. But the reinforcement distributed in the post-liquid phase in the matrix uniformly. By hot extrusion or semi-solid injection molding, the strength of the composites increased dramatically. On the other hand, AZ91D matrix composites exhibit good age hardening ability because of good heat-stability of interface structure between reinforcement and matrix.

Disclosed are examples of a system for laterally shifting a longitudinally moving strip material as it enters a joining mechanism that urges the strip material into contact with a moving sheet material. The system may include a continuous supply of the strip material longitudinally moving in a downstream direction toward and into the joining mechanism, an electric motor having a drive shaft; and a strip guide arm connected to the drive shaft and situated upstream of the joining mechanism, the strip guide arm having a downstream strip retainer that slidably retains the strip material on the strip guide arm at a downstream location on the strip guide arm.


With the current trend in lieu of the ongoing pandemic, online learning and technology-based pedagogy receive worldwide attention. There are several pedagogical practices one can use to evaluate students mindful and the method will vary based on the learning objective. In this paper, our goal is to dive deeper into identifying the best keyword extraction technique which can be closely mapped with human evaluation. We report the results of three popular keyword extraction techniques specifically RAKE, TF-IDF, and Semantic Fingerprinting on the dataset generated from the discussion board post of a Learning Management System. The results illustrate that the TF-IDF algorithm shows the highest correlation with a human evaluation with 0.76 correlations, RAKE with 0.36, and Semantic Fingerprinting with 0.58. It was also identified Semantic Fingerprinting had a lowest mean square error of 18.26.


ABSTRACT In the wake of the recently emerged COVID-19 pandemic, legislatures were regarded as one of the important government institutions that can help cushion nations against the economic and social disruptions inflicted by the health crises, given the important roles they play in policymaking within political systems. This paper examines the roles played by Ghana's legislative institution in the management of the COVID-19 pandemic. The paper further explores some of the challenges to legislative activities during the height of the pandemic. From a content analysis of a variety of literature drawn from Parliamentary Proceedings, online journal articles, official documents, and news from credible media outlets, we found that Ghana's legislative institution was crucial to the country's management of the pandemic as they played important roles such as passing COVID-19 related laws, financial oversight, and providing a check on Executive actions. The main challenge to Parliamentary activities was the demand for rapid legislation, which weakened Parliamentary oversight and scrutiny functions. The study makes some recommendations to strengthen legislative responses to future pandemics.


In view of the complexity of the using such languages as C language in mechanical design,it is suggested to use MATLAB to solve all kinds of single objective optimization and multi-goal optimization in this paper.And the example of using V-belt optimized design is given to show the whole process and its validity has been proved.


Structural silicone sealant(structural sealant for short) for building is able to transfer the load and deformation of the glass to the architectural structure.The strength and deformation performance of the silicone sealant after aging become badly in different degree,and easy leads to accidents.In this paper,laboratory hot air ageing and fluorescent UV aging experiments was done for 8 type samples of structural sealant,and the changing direction of adhesive strength was studied in different aging ways.Meanwhile,Aging rate of the structural sealant's adhesive strength was calculated,and a property aging model of the structural sealant was proposed.At the end,it offers some specific suggestions regarding the application,making it possible to calculate the aging degree and future available time of specific structural silicone sealant.


INCE the fall of 1957, in the Delmarva area, we have seen an acute disease of chickens with increasing frequency. This malady, which appears to be infectious and contagious, is characterized by ruffled feathers, watery diarrhea, trembling, and severe prostration. It seems to spread from pen to pen within a poultry house, and tends to recur in successive broods. The initial outbreaks occurred in and around an area known as Gumboro, in southern Delaware; hence, the common name of "Gumboro disease." The term avian nephrosis has been applied to this new disease because of the tubular degenerative lesions in the kidneys. Specific characteristic signs and lesions set off the condition as a definite entity.


This article considers how, and to what extent, the ideas and theories developed by Lombrosian, Positivist criminology were received and came to be embedded in Sweden. It demonstrates first the way in which new criminological ideas were widely reported in the press and by other means in nineteenth-century Sweden, partly due to Lombroso's own celebrity but also partly due to public interest in the proceedings of international congresses. It then goes on to analyze the way in which ideas of "the born criminal" and the social bases of crime came to be seen, by some, as a challenge to the existing political order. Finally, the article considers the impact of Positivist criminology in the spheres of medical discourse and jurisprudence.

A method has been developed for estimating the parameters of virtual musical instrument synthesizers to obtain isolated instrument sounds without distortion and noise. First, a number of instrument sounds are generated from randomly generated parameters of a synthesizer. Lowlevel acoustic features and their delta features are extracted for each time frame and accumulated into statistics. Multiple linear regression is used to model the relationship between the acoustic features and instrument parameters. Experimental evaluations showed that the proposed method estimated parameters with a best case error of 0.004 and signal-to-distortion ratio of 17.35 dB, and reduced noise to smaller distortions in several cases.


Treatment of 2,4-diacetyldeuteroporphyrin IX with oxalyl dichloride and t-butyl alcohol gives mainly the two isomeric mono-t-butyl esters, 10 and 11, which can be separated by thick-layer chromatography on silica gel. These monoesters can be individually transformed, via a sequence of steps, into the corresponding isomerically pure protoporphyrin IX monomethyl esters, 5 and 6, one being the magnesium (II)-free derivative of a key intermediate in the biosynthetic pathway to chlorophylls and bacteriochlorophylls. The isomerically pure monomethyl esters 5 and 6 were magnesiated and the resulting magnesium(II) protoporphyrin IX monomethyl esters 2 and 4, respectively, were challenged with a suspension of isolated developing chloroplasts in the presence and absence of added S-adenosylmethionine. The isomerically pure isomer which was converted into magnesium(II) 2,4-divinylpheoporphyrin a53 in the absence of the SAM cofactor was identified as the physiologically significant 6-methyl ester 2.


Abstract : Forward Deployed Naval Forces is not a new concept or strategy. In fact, it was utilized by other nations such as the British and French prior to World War II. The United States has also stationed naval forces in areas that were previously colonized such as the Philippines after the Spanish American War. Today the United States has naval ships stationed in forward bases in Japan, Spain, Italy, and Bahrain. The aim of this thesis paper is to study and analyze the stationing of a capable naval force in the Republic of the Philippines to provide a stabilizing presence in the South China Sea. This research focuses on the strategic location of the Philippines and the surrounding islands that can provide an immediate access to the South China Sea. This thesis details the Republic of the Philippines and People's Republic of China territorial dispute in the South China Sea region and its potential effects in destabilizing government relations. This research is conducted to study and analyze the basing of a U.S. naval force in the Republic of the Philippines. The results should provide an overview of the social aspects, political climate, and military outcomes that influence basing in the region.


Dilute droplets form upon changing the temperature of a phase separated polyelectrolyte complex coacervate. This provides an in situ approach to measure the interfacial tension between supernatant (dilute droplet) and dense coacervate by the deformed drop retraction (DDR) method. The aqueous coacervate, formed via a model 1:1 by charge stoichiometric polyelectrolyte blend, exhibits ultralow interfacial tension with the coexisting phase. DDR finds the interfacial tension scales as γ = γ 0(1 - C s/C s,c) μ , with μ = 1.5 ± 0.1, γ 0 = 204 ± 36 μN/m, and C s,c = 1.977 mol/L. The value of μ independently validates the classical exponent of 3/2. The scaling holds between C s/C s,c of 0.75 to 0.94, the closest measurements to date near the critical salt concentration (C s,c). The temperature dependence of the interfacial tension is consistent with observed lower critical solution phase behavior and classical scaling. A detailed account of the DDR method and validation of assumptions are demonstrated.


Unbaked earth structures, like adobe structures are found in abundance throughout the world. Like most structures, they are subject to deterioration through time. The preservation of historic adobe structures requires careful attention and evaluation of several factors, but material erosion is the main concern. In order to calculate the amount of erosion, accurate measurement of the structures is required. Any measurement method used to quantify erosion needs a level of accuracy to detect the small changes in the surface of the structures. Digital photograrnrnetry is the measurement of objects by digital image analysis using specialized software packages. Historic preservationists and architects use digital photogrammetry to measure historic structures. The accuracy of the measurement process is crucial, especially when an accuracy of less than 118" of an inch is required. Erosion measurements of historic adobe wall ruins at Fort Davis National Historic Site requires this level of accuracy in order to quantify volume differences that are used to calculate erosion rates. An experiment was conducted to investigate how; the combination of photographs taken from different positions; the resolution of digital images and the dimensional control withm the image effects the accuracy of the measurements. The experiment compared measurements from a model eroded adobe wall using digital photogrammetry with measurements obtained using a 3D digitizer, a method whose accuracy is assumed to be perfect. Multiple regression models identified factors affecting accuracy and precision, and magnitude of the effect. The results of the regression models were used to make


O2-generation rate (Vo2-) in microsomal, mitochondrial and nuclei liver membranes was measured by ESR method, by accumulation of stable nitroxide radicals. These Vo2- values were compared with Cu, ZnSOD and MnSOD activities after 2 hours ischemia and 24 hours reoxygenation. O2- radicals generated by electron transfer chains are concluded to damage mainly during the ischemia, but not the reoxygenation.


Abstract Population studies have shown that overall prevalence of mild to severe mental retardation ranges from 2.5 to 5 per thousand. Genetic contribution to this group accounts for 15-30%. The role of chromosomal fragile sites in cancer, recurrent abortions and fertility failure were reported in the literature, which prompted us to look in to the possible causative role of fragile sites with mental retardation. Herein, we discuss the frequency, association and genetic implications of chromosomal fragile sites with mental retardation.

Hydrated rare earth carbonate single crystals were obtained in metasilicate gels. The formulas of the crystals were determined to be (RE)2(CO3)3·8H2O (RE=La, Pr) and (RE)2(CO3)3·4.54H2O (RE=Nd), and the crystal structures were determined to be of the lanthanit type.


Based on the plastic strain distribution obtained from elasto-plasticity FE simulation,the influence of seepage on the failure mechanism is studied through comparison of mechanism under dry or drained conditions.A new failure mechanism under seepage conditions is proposed by improving the mechanism under dry or drained conditions.The face stability of shield tunnel is studied,and the upper-bound solution of limit support pressure is calculated.The proposed method is verified through case studies and applied to the analysis of face stability for Qianjiang tunnel.The analysis shows that the seepage has influence on the failure mechanism of tunnel face,and that if the ground water table is lower than the ground,the influence will be the same and independent of the tunnel diameter and the friction angle.A large part of support pressure is used to equilibrate the seepage force,and the total support pressure almost has linear relation with the water level.


Measurements of magnetization at 4.2 K and paramagnetic susceptibility up to room temperature have been done on Gd-Sm single crystals and polycrystals less than 30 at.% Sm concentration. The magnetic structure is a ferrimagnetic configuration in the ordered regions for the measured samples. The magneto-crystalline anisotropy constants K 2 0 and K 4 0 were determined from the analysis of magnetization curves on the basis of the molecular field theory. The values of K 2 0 and K 4 0 are negative and positive, respectively, in all concentration ranges, and the magnitude increase quadratically with increasing Sm concentration. From these results, the values of the anisotropic exchange interaction between two magnetic ions in the Gd-Sm alloys, K 2 0 (AEI) Gd-Sm and K 2 0 (AEI) Sm-Sm , were estimated to be 42 and -24 cm -1 , respectively.


Summary: Purpose: We report a patient with mesial temporal lobe epilepsy (MTLE) with olfactory prodromal symptoms manifested as an unpleasant smell of onions, who was found to have an ipsilateral deficit of olfactory naming (olfactory agnosia).


Background. In conditions of tuberculosis inflammation decompensation occurs in the system of lipid peroxidation- antioxidant protection, an important role in which belongs to the mechanisms of oxygen transport by blood. Purpose of the study. To study the features of blood oxygen transport and prooxidant-antioxidant state, depending on the character of the tuberculosis process. Material and methods. A total of 120 patients with various types of the tuberculosis process in the lungs were examined. In the first 10 days, after admission of the patient to the hospital, 10 ml of blood was taken from the ulnar vein under the restored outflow. Evaluation of blood oxygen transport was performed within an hour after venous blood sampling. The rest of the blood was separated by centrifugation into plasma and erythrocyte mass, which were stored at -80° C with the subsequent measurement of prooxidant-antioxidant status within one month.Results. The blood oxygen transport and prooxidant-antioxidant balance were analyzed for different types of the tuberculosis process. The most significant increase in p50 was observed in the advanced tuberculosis process (by 13.06% (p <0.05), in the presence of destruction in the lung tissue (by 13.06% (p <0.05).), in the presence of bacterial excretion (by 10.07% (p <0.05).) and in the multiple drug resistance of mycobacterium tuberculosis (by 9.89% (p <0.05). This was  ccompanied by more pronounced activation of lipid peroxidation processes and a decreased antioxidant reserve. Conclusions. Changes in the blood oxygen transport as well as the activity of free radical oxidation in pulmonary tuberculosis depend on the extent of the tuberculosis process, the presence of destruction in the lung tissue, bacterial release and the presence of multiple drug resistance. The revealed features justify the administration of antioxidant therapy and drugs promoting tissue oxygenation.


Purpose – The purpose of this study is to describe the design and delivery of an English language course aimed for in‐service librarians and to report about the effects of the blended delivery mode on the learning experience.Design/methodology/approach – The paper describes the broader context in which the course was developed, its goals, the way it was planned and delivered in a blended mode, the participants' perception at the end of the course and after one year and the Learning Management System which was used (Moodle).Findings – Blended learning in workplace instruction is very fruitful, especially when applied to language learning, as it allows one to establish a collaborative environment and to stretch the learning experience over a longer time, at the same time limiting the absence from work. This involvement is possible only when the topics are close to the participants' professional interests and the teacher stimulates collaboration.Practical implications – The course model could build up the ba...


This paper reports the results of a study to understand the preferences of pedestrians towards different types of crossing facilities in an area surrounding a 6-lane busy road in London. Participants were first asked to indicate how comfortable they feel using different types of crossings. Footbridges and underpasses were systematically rated below signalised crossings, but staggered signalised crossings were rated slightly higher than straight ones. Participants were then presented with a scenario where crossing the road is impossible and asked to choose between walking a given time and use a certain type of facility or avoid crossing the road altogether. The analysis of the choices using a mixed logit model revealed that participants chose staggered signalised crossings, footbridges, and underpasses, if the walking times to those crossings were respectively 1.5, 4.2, and 5.7 minutes smaller than the times to access straight crossings. The "don't cross" alternative was chosen only if the straight crossings were located 18.5 minutes away. Older participants required higher reductions in order to use underpasses rather than straight crossings, and people who cross the road most days require lower reductions to use the three types of alternative facilities. The study provides information that is useful when planning changes in the frequency and type of facilities to cross busy roads.


Purpose – The purpose of this paper is to consider the unsteady natural convection flow of a viscous incompressible fluid, which is induced by differential heating on the solid vertical boundary of an open‐ended rectangular cavity with the two horizontal surfaces which are permeable and maintained at the temperature of ambient fluid. Attention is focused on how the flow and heat transfer is affected by variations of the buoyancy force, as well as by the permeability of the surfaces.Design/methodology/approach – An upwind finite‐difference method in conjunction with a successive over‐relaxation iteration technique is used to solve the governing boundary layer equations. To do this, the first and second derivatives were approximated by central differences and were used in the vorticity, energy and Poisson equations. To preserve the conservative property, the finite‐difference forms of the vorticity and energy equations were written in conservative form for the convective terms.Findings – Local rate of heat ...

45 46 Objective: Autoimmune polyendocrine syndrome type 1 (APS 1) is caused by mutations in the AIRE 47 gene that induce intrathymicT-cell tolerance breakdown, which results in tissue-spe cific autoimmune 48 diseases. Design: To evaluate the effect of a well-defined T-cell repertoire impairment on humoral 49 self-reactive fingerprints, comparative serum self-IgG and -IgM reactivities w ere analyzed using both 50 oneand two-dimensional western blotting approach es against a broad spectrum of peripheral tissue 51 antigens. Methods: Autoantibody patterns of APS 1 patients were compared with those of subjects 52 affected by other autoimmune endocrinopathies (OAE) and healthy controls. Results: Using a Chi53 square test, significant changes in the Ab repertoire were found when intergroup patterns were 54 compared. A singular distortion of both serum self-IgG and self-IgM repertoires was noted in APS 1 55 patients. The molecular characterization of these antigenic targets was conducted using a pro teomic 56 approach. In this context, autoantibodies recognized more significantly either tissuespecific antigens, 57 such as pancreatic amylase , pancreatic triacylglycerol lipase and pancreatic regenerating protein 1 , or 58 widely distributed antigens , uch as peroxiredoxin-2, h eat shock cognate 71-kDa protein and aldose 59 reductase. As expected, a well-defined self-reactive T-cell repertoire impairment, as described in APS 60 1 patients, affect ed the tissue-specific self-IgG repertoire. Interestingly, discriminant IgM reactiv ities 61 targeting both tissue-specific and more widely expressed antigens were also specifi cally observed in 62 APS 1 patients. Using recombinant targets, we observed that post translational modifications of these 63 specific antigens impact ed upon their recognition. Conclusions: The data suggest that T-cell64 dependent but also T-cell-independent mechanisms are involved in the dynamic evolution of 65 autoimmunity in APS 1. 66 67


Menopausal women experience physical and hormonal changes so that it often causes problems. This study is generally to identify menopausal women's perception toward signs and symptoms of menopause in Kalijaga which is claimed as the village with the highest number of menopausal women in Cirebon. This study used descriptive quantitative research by applying the cross-sectional approach. The population of this study was women aged 45-55 years which were chosen using purposive sampling technique. Menopause Rating Scale (MRS) was used as the instrument of the study. The data were analyzed using descriptive analysis. The findings showed that there were some signs and symptoms experienced by the respondents namely hot flushes and sweating (90.7%), heart discomfort (46.4%), sleep problems (72.2%), depressive mood (70.1%), irritability (76.3%), anxiety (75.3%), physical and mental exhaustion (80.4%), sexual problems (58.8%), bladder problems (71.1%), vaginal dryness (74.2%), joint and muscular discomfort (89.7%). The symptoms had different levels of severity and include all three dimensions. In addition, Most of the respondents had negative perceptions toward the signs and symptoms of menopause. Based on the result of the study, it can be concluded that the respondents experience eleven signs and symptoms of menopause at varying scales of severity. It is suggested for the respondents to recognize the signs and symptoms of menopause and utilize health services in order to address the problems due to the signs and symptoms of menopause. It is also recommended for the respondents to follow elderly health programs.Keywords: Menopause, Perception, Signs, and Symptoms


not simply to digest vast amounts of Latin but to speak it too throughout the school day. This, he argues, is why classical allusions in Shakespeare are a 'part of the texture of communication' (24). In a creative borrowing of his own from John Kerrigan's reading of Hamlet as a play about remembering (repr. in Revenge Tragedy (Oxford 1996)), Burrow argues that Shakespearian classical appropriations are themselves acts of remembering, and often misremembering, the language of humanism.


BATTAGLIA, Stela Maris Fazio. Questions of language in Robinson Crusoe: the dialogics of words in a lonely life. 173 f. Thesis (Doctoral degree) – College of Education, São Paulo University, São Paulo, 2009. The following thesis presents a study on Daniel Defoe's literary creation Robinson Crusoe, written in 1719. Its status as a literary classic that has been the subject of endless adaptations gives Robinson Crusoe an extraordinary position in the discursive chain, revealing the character as a myth. The present study, based on Mikhail Bakhtin's concept of creative understanding, sought to amplify the meanings in the analysis of its empirical object, with the following aims: to question the possible use of classic works as fetishes, to empty its meanings and to investigate the hypothesis of Robinson Crusoe being a prototype of man as a being of language, a metalinguistic being. This hypothesis was enabled by the concept of the dialogism of language, understood within the concept of Bakhtin's Circle. The methodology employed consisted of successive readings of the work, the selection of acts of language expressed by the character, and their classification into categories. From this basis, the representations of the Other in Robinson's enunciations during his period of total isolation on the island where he was shipwrecked were sought; the search was guided by the concept of the dialogic constitution of speech, since within the context of the enunciation there were no actual conversational partners present. To stress the dialogic character of language, a selection was also made of the signs of the Other in the character's autobiographical account (the work as a whole), some of which were explicitly visualized. The reflections of different authors are present in this study: Roland Barthes, Michel de Certeau, Jeanne Marie Gagnebin, Ivonne Bordelois, Zygmunt Bauman, Dominique Maingueneau, Fernando Savater, David Olson, and George Steiner. The results of this study confirm the correctness of the hypothesis proposed and demonstrate the strength of language in human life, supporting the need to value speech in the midst of the cultural crisis of liquid modernity.

Today HIV/AIDS has become one of the most devastating disease mankind has ever faced. Since the epidemic began, it has become one of the largest causes of death worldwide. HIV continues to spread through out the world, by increasing challenges to human rights, at both national and global levels. The virus continues to be marked by discrimination against population groups; those who live on the fringes of society or who are assumed to be at risk of infection because of behaviour, race, ethnicity, sexual orientation, gender, or social characteristics that are stigmatized in a particular society. Since HIV/AIDS is a problem that profoundly affects most aspects of people's lives, it raises many social, economic and cultural issues that relate to human rights, ethics and law. HIV/AIDS therefore is a problem that does not respect national borders and there is evidence that unless prevention efforts are sustained, new epidemics of HIV can readily arise to threaten peace, human rights, security and survival. A new approach is required to halt and begin to reverse the epidemic.


This paper applies fuzzy reinforcement learning along with state estimation to the differential pursuit-evasion game. The proposed algorithm is a modified version of the Q(λ) Learning Fuzzy Inference System (QLFIS) algorithm proposed in [10]. The proposed algorithm combines the QLFIS algorithm with a Kalman filter estimation approach. The proposed algorithm is called the modified Q(λ)-learning fuzzy inference system (MQLFIS) algorithm. The Kalman filter is used by the pursuer to estimate the expected future position of the evader. The proposed algorithm tunes the input and the output parameters of the fuzzy logic controller (FLC) of the pursuer based on the expected future position of the evader instead of the real position of the evader. The proposed algorithm also uses the expected future position of the evader to generate the output of the FLC so that the pursuer captures the evader at the expected future position. The proposed algorithm is used to learn two different single pursuit-evasion games. Simulation results show that the performance of the proposed MQLFIS algorithm outperforms the performance of the QLFIS algorithm proposed in [10].

Plant spacing and weeding are among the key factors determining leafy vegetable growth and yield through maximum utilization of space, nutrients, water and sunlight. Amaranthus species is a popular and very important leafy vegetable crop that is infested and damaged by the arthropod pests in Nigeria. Therefore, this study identified the optimum spacing and proper weeding regime required for the control of leafy caterpillars (Hymenia recurvalis F.) and ensuring the potential yield of amaranths. Field experiments were conducted to evaluate the effects of plant spacing and weeding frequency in the control of leafy caterpillar infestation and damage on amaranths (Amaranthus sp.). Four intra-row plant spacing (10 x 10 cm; 20 x 20 cm, 30 x 30 cm and 40 x 40 cm) and four weeding frequencies (0, 1, 2 and 3) were assessed using split-plot laid in randomized complete block design (RCBD) replicated three times. Results showed that 40 x 40 cm intra-row plant spacing and three weeding were found to be effective in reducing the infestation of H. recurvalis on Amaranthus sp. Results further showed that these combined management practices improved the growth and yield of the crop by 35% during the 2020 and 2021 cropping seasons in the study area. The study showed that combining appropriate plant spacing with three weedings is recommended for the control of amaranths leaf caterpillar (H. recurvalis) to poor resource farmers in the study area. Keywords: Intra-row, frequency, amaranth, Hymenia recurvalis, weeding, plant spacing.


In order to investigate the calculation ability of meshless method and calculation precision for lift and drag force coefficient based on N-S equations with S-A turbulence model and Euler equations, numerical simulation of flow field around the DLR-F4 wing-body, supplied by the AIAA Drag Prediction Workshop, is employed using meshless method. Furthermore, the calculated results are compared with experiment results and Waller's simulation results achieved by MGAERO software. It's found that the present simulation results without consideration of fluid viscosity don't agree well with Waller's and experimental results. The present simulation results with consideration of fluid viscosity were found to be in good agreement with experimental results. These results indicate that meshless method coupled with S-A turbulence model could predict the natural flow characteristic around the DLR-F4 wing-body configuration well.


We present here the concept of "in-plant" NMR and show that high-resolution NMR spectroscopy is suitable for the analysis of intact plants and can be used to follow the changes in the intraorganismal molecular composition over long time periods. The NMR-based analysis of the effect of different concentrations of heavy water on the aquatic plant Vesicularia dubyana revealed that due to the presence of specific adaptive mechanisms this plant can sustain the presence of up to 85% of D2O. However, it dies in 100% heavy water.


Background Some studies had reported that patients with viral hepatitis are at increased risk of reduced bone mineral density and even osteoporosis. However, the interaction between reduced bone mineral density (BMD) and viral hepatitis remains inconclusive. Therefore, our study collected hepatitis test results and bone mineral density from respondents in the NHANES database. The aim of this study was to investigate whether there is an association between hepatitis and a decrease in bone mineral density. Methods The respondents with both hepatitis- and BMD-related indicators from the NHANES database in the United States from 2005–2010, 2013–2014, to 2017–2020 were collected for this study. BMD were compared between respondents who were positive and negative for respondents related to hepatitis B and C. BMD was measured using dual-energy X-ray absorptiometry of the femur and lumbar spine. Finally, multiple regression analysis was performed between hepatitis B surface antigen (HBsAg) and hepatitis C RNA (HCV-RNA) and BMD in the respondents. Results A total of 15,642 respondents were included in the hepatitis B surface antigen-related survey. Of these, 1,217 respondents were positive for hepatitis B surface antigen. A total of 5111 hepatitis C RNA-related responders were included. Hepatitis C RNA-positive had 268 respondents. According to the results of the multiple regression analysis, the femoral BMD was significantly lower in HBsAg (+) respondents compared to HBsAg (–) respondents: −0.018 (−0.026, −0.009) (P < 0.01). Moreover, spinal BMD was significantly lower in HBsAg (+) respondents compared to HBsAg (–) respondents: −0.020 (−0.030, −0.010) (P < 0.01). According to the results of multiple regression analysis for hepatitis C RNA, HCV-RNA (+) respondents had significantly lower BMD compared to HCV-RNA (–) respondents: −0.043 (−0.059, −0.026) (P < 0.01). Conclusion During the analysis of respondents in the NHANES database in the United States, positive tests for hepatitis B surface antigen and hepatitis C RNA were found to be associated with a reduction in BMD. Positive serology for these hepatitis indicators may increase the risk of reduced BMD. Of course, this conclusion still needs to be further confirmed by more large clinical trials.


The present work focuses on the verification of compliance with the program of integral management of solid waste of a SITP concessionaire, taking into account the great problem that Bogota has against the inappropriate management of waste, as well as verifying the Integral Management Plan of Solid Waste - PGIRS which has consigned all the activities and procedures to be carried out for the management of the company's waste using a methodology focused on 4 stages, of documentary review, description of the plan, verification of the legal framework and opportunities for improvement , resulting in the inclusion of important measures for the special handling of used batteries and used tires. It is important to highlight that the concessionaire has a specific PGIRS for the waste generated there, however there are some improvement opportunities compared to the used batteries and tires, which are characterized by being high environmental impact wastes.

Halina Kaczmarek, Sebastian Tyszkowski: The use of the aerial and ground photogrammetry in the Jeziorsko Reservoir shore zone monitoring (the Warta River, Central Poland). Geomorpholo- gia Slovaca et Bohemica, 9, 2009, 2, 2 figs., 9 refs. The Jeziorsko Reservoir was created between 1986-1992 on the Warta River, and it is one of the largest reservoirs on the Polish lowlands. The reservoir is 16 km long and its capacity exceeds 202.3 mln m 3 , the coast line has over 44.3 km. The banks are built with Quaternary glacial sediments (tills, sands and clays), and in a few places with Pliocene clays. Since 1992, when the filling was completed, the coast line has started the evolution of accumulation, abrasion and erosion processes. The high water level fluctuations during the exploitation of the reservoir amount to 5 m·y -1 . Additionally, they intensify the natural coast transformations. The main goal of the researchers is to create a model of the coastal line evolution on the reservoir high water fluctuations. The paper aims at presenting the contemporary re- search methods based on the Geographical Information Systems (GIS), which may be used for suppor- ting and analyzing the morphodynamic processes (geomorphological and fluvial) of reservoirs. Due to the fact there had been no earlier research, it was necessary to use a method which would give a compe- tent quality and credibility measure of the changes. Authors have aimed to reconstruct the conditions of the bank dynamics since 1986. The following cartographic and photogrammetric materials were used: a topographic maps at a scale of 1:5000, 1:10000 aerial photographs taken in 1991 and 2004 and an or- thophotomap from 2005 at 1:5000 scale. The ground photogrammetry was used to record the current processes in the coastal zone such as mass movements (topples, landslides) and bank erosion. Other data from field studies were collected by means of the Global Positioning System (GPS). The changes in the reservoir coastal zone detected on the aerial photographs were mainly situated in the highest bank zone. The ground photogrammetry is being used for current coast and abrasion monitoring. Images are wor- king as stereopairs, are taken for stereoscopic analysis and as individually for the seasonal metric mea- surement. Thanks to the use of the GIS, the achieved horizontal mean accuracy was below 0.5 m for photogrammetry and 0.3-1.0 m for ground photogrammetry. At present, the database makes use of a mobile as well as a desktop GIS.


Cellasto components excell by very interesting property combinations, i.e. extremely high volume compressibility with very low lateral extension and excellent resilience, even under high dynamic load bearing. A further important characteristic property is the resistance of Cellasto to mechanical, chemical and biological impacts. Cellasto exhibits these properties over a wide temperature range and thus allows for tailor-made products for specific applications, the components keeping the properties. The components are produced observing environmental aspects


Large-scale electric vehicles (EVs) connected to the power system would bring extensive negative impacts on power system operation and control. Based on this situation, this paper puts forward a coordinated schedule strategy about the charging and discharging of electric vehicles both at the scale charging station and smart residential area. The strategy adopts the demand response (DR) scheme, namely, the charging and discharging behavior of the electric vehicles are controlled by the time-of-use price (TOU). With the electricity price as a level, in order to smooth the fluctuation of load and enhance the profit of users, this paper builds a scheduling strategy model and solved by adaptive mutation particle swarm optimization to reduce the influence of premature of standard particle swarm algorithm on optimization result. Finally, through examples, the reasonable pricing mechanism for peak-valley charging and discharging as proposed in the paper has proved to be effective in smoothing the system load, and the users' economic benefits are satisfied at the same time. Meanwhile, the performance contrast between traditional PSO algorithm and improved PSO algorithm, it is proved that the latter is more effective for dealing with high-dimensional problems.


A new versatile mediator for conducting "living" radical polymerization was developed based on diselenocarbonyl compounds. After the optimization of substitution groups, a "universal" diselenocarbonyl compound (O4) was developed and successfully applied to the controlled polymerization of both conjugated and unconjugated vinyl monomers, and the desired polymers with predetermined molecular weights and narrow molecular weight distributions were obtained in excellent yields. The characteristic feature of this method is exemplified by the synthesis of block copolymers composed of conjugated and unconjugated monomers, which would be of great importance as functional smart organic nanomaterials. Furthermore, the existence of organoselenium groups in the final polymers would be especially valuable for bio-related applications.


The Attitude Toward Physical Activity Questionnaire was utilized to study the importance of nine dimensions (social experience, health and fitness, thrill and risk, beauty in movement, release of tension, prolonged and strenuous training, pursuit of victory, demonstration of ability, competition) in involvement in physical activity of 50 male and 50 female athletes and 100 nonathletes. Factor analyses of intercorrelations among the dimensions reduced these to three factors (competition, health and fitness, social experience). Mean factor scores showed that the total sample rated health and fitness as significantly more important than the other two as a motive for involvement in physical activity. A 2 × 2 multivariate analysis of variance showed a significant relationship between sex and skill and the factors. Further univariate analyses showed that men and women similarly rated health and fitness the most important, but women rated competition significantly lower and social experience significantly higher than men. Athletes differed significantly from nonathletes only in the assignment of higher scores to competition.


Stress analysis of the bender components in the design of the begel fabricator machine was carried out using FEA (Finite Element Analysis) with three variations of the constituent material parameters, namely 6061 aluminum, mild steel, and cast iron with a modulus of elasticity of 68.9 GPa, 220 GPa, 120.5 GPa, respectively. The test is carried out by a loading parameter 2520 MPa and fixed constraint. The maximum von misses stress and displacement obtained for each material parameter components using aluminum, mild steel, and cast iron are 17.78 MPa; 0.00765, 17.49 MPa; 0.00229, 17.62 MPa; 0.00427 respectively.


Background: Suicide is a worldwide problem caused mainly by feelings such as frustration, loss of values such as dignity, respect for self and neighbor. Young university students are in a "vulnerable" stage for the development of suicidal risk behaviors, which implies profound biological, psychological and social transformations, largely generating crisis, conflicts and contradictions. Materials and Methods: A cross-sectional study included 2,624 nursing students where the Suicidal Risk Assessment in Adolescents (IRSA) was applied, made up of 107 questions in 8 dimensions of suicidal behavior: suicidal risk factors not modifiable, modifiable, depression-anxiety, suicidal ideation, precipitating factors, beliefs and protectors to suicide. Results: The history of suicide attempt (HIS) was presented in 20% and 61% reported having suicidal ideation. Students with HIS had significantly higher frequency of risk factors vs. students without HIS; the proportion of protective factors was significantly higher in those without HIS. The highest frequency with HIS was between 20 to 25 years, in the female sex and in face-to-face careers. Conclusion: The results show that suicidal behavior in nursing students of the CUCS, UDG, should be considered a problem of public health; The humanistic approach allows us to realize an existential void and the lack of a sense of life to face the demands of modern society that limit the development of human potential to cover the basic needs of human coexistence and self-regulation.

ONE of the best-known tales in Norse mythology is the story of Skirnir's journey to woo Gerd, the sea-giant Gymir's daughter, on behalf of his master, the Vanr-god Frey. It is told in two slightly different versions: Skirnismdl, a poem in the poetic Edda, also called F6r Skirnis, and a prose version by Snorri Sturluson, the 13th century Icelandic poet and historian.' Snorri's version is found in Gylfaginning, part II of his Edda, the so-called prose Edda which he wrote about 1223, three centuries or so, it is thought, after the composition of Skirnismndl, but there are no definite pointers to the date of the poem.2 Gylfaginning, 'The Deception of Gylfi,' is a frame story about the visit of a Swedish king to the abode of the Aesir, who in Snorri's narrative are not gods but human wizards. For Skirnis is one of the mythic tales contained in this frame. In a few introductory lines to Skirnismndl we are told that one day Njord's son Frey sat down in the seat called Hlidscidlf From there he could overlook the whole world including Jditunheim, the home of the giants, where he saw a beautiful young woman walking across the yard in Gymir's homestead. This sight caused him much mental anguish, and Njord and his wife Skadi summoned Skirnir, Frey's trusted servant, and asked him to find out what was troubling his master. In the poem Skirnir does what is requested, but with some reluctance since he expects angry words from his master if he disturbs him. After some persuasion Frey reveals to him the reason for his withdrawal: he happened to see a maiden in Gymir's stronghold and fell in love with her, but sadly doubts that the gods and elves will allow the consummation of this love for Gymir's daughter. Skirnir offers to woo the maiden on his behalf on condition that Frey gives him a horse that can carry him through the dark magic curtain of fire surrounding Gymir's stronghold, and the sword that fights by itself against the giants. This is granted him at once, and in a single stanza spoken by Skirnir to the horse we are told about the dangers they are encountering on the journey. It is made in darkness across the wet mountains in giant-land, where they may be caught by the loathsome giant. A brief narrative in prose informs us that Skirnir has arrived at Gymir's stronghold, where he faces a giant shepherd sitting on a mound by the gate where fierce hounds are tethered. The poem resumes with a dialogue between Skirnir and the shepherd, who tells him he will never be able to pass the gate alive or speak to Gymir's daughter; but Skirnir, who believes that whatever action he takes now cannot alter the day on which he is doomed to die, fights his way past the shepherd into the stronghold. He is received by Gerd, who with her servant has heard the din of the fight and guesses that the dismounting stranger must have killed her brother, presumably the guardian shepherd. When she learns the reason for his visit,

They are concerned about the detrimental affects on young persons who are placed in detention rather than meeting their accommodation, health, education and other needs.


Tetracycline with the broad-spectrum antibacterial ability,has been largely used in animal husbandry industry.However,illegal administration will lead to residues in the animal food.Traditional detection methods have the disadvantages such as complex program,time and energy consuming,costly equipment,and difficulty to implementon-line,real-time and mass detection,but the immunoassay can make up these shortcomings.In this paper,tetracycline residues,damage and immunoassay will be reviewed.


We investigate the modulational instability (MI) of the optical beam propagating in the relaxing saturable nonlinear system. We identify and discuss the salient features of various functional forms of saturable nonlinear responses such as exponential, conventional and coupled type on the MI spectrum. Using suitable model, the relaxation of the nonlinear response is effectively included alongside the saturable nonlinear response (SNL) of the medium. The linear stability analysis is performed and an explicit dispersion relation is determined for various functional forms of SNL. Firstly, we analyze the impact of SNL on the MI spectrum and found that the MI gain and bandwidth is maximum for exponential nonlinearity in comparison to other types of SNLs. Latter the relaxation of the nonlinearity is included, the inclusion of the finite value of the response time extends the range of the unstable frequencies literally down to infinite frequencies. In the regime of slow response, the MI gets suppressed and it is found to be irrespective of the signs of dispersion coefficient. The saturation on the other hand inhibits the MI with increase in saturation parameter. To give better insight into the MI phenomena, the maximum MI gain and the optimum modulation frequency is drawn as a function of the delay. Thus the MI dynamics in the system of relaxing saturable nonlinear media is emphasized and the significance of various functional forms of SNL are highlighted.


Chip packaging is an important process during IC manufacturing. Wire bonders are key equipments of chip packaging. The manually type of wire bonders can be updated to automatic with a pattern recognition system (PRS). However, the resolution of PRS is quite sensitive to the mechanism's trembling. Additional waiting time has to be taken before the image sensor can take a shoot, which limits the wire bonder's productivity. In this paper, method for motion blurred image restoration is presented. The method uses point spread function (PSF) learning to estimate the degradation function and power spectrum analyze to estimate the image's signal to noise rate (SNR). Experimental results are given to illustrate the proposed image restoration algorithm.


The spectrum above 100 GHz has the potential to enable accurate 3D wireless localization due to the large swath of available spectrum. Yet, existing wide-band localization systems utilize the time of arrival measurements requiring strict time synchronization. In this paper, we present 123-LOC, a novel non-coherent system for one-shot dual-polarized 3D localization above 100 GHz. Our key idea is to create unique asymmetric THz fingerprints in 3D so that a wireless node can jointly infer its angular position and distance by taking hints from the measured power-spectrum profile. We introduce a dual-polarized dual-slit waveguide structure that emits out signals into free-space with a key feature that the beam pattern depends on the frequency of the signal and the geometry of the slit. To distinguish the emissions from the two slits, we use polarization diversity and manipulate the aperture geometry of the two slits so that they transmit slightly different angular-spectral signatures. Our over-the-air experiments demonstrate that 123-LOC achieves an average angle estimation error of 1° together with millimeter-scale ranging resolution, solely through non-coherent power measurements.


Background:  Elevated fractional exhaled nitric oxide (FENO) associates positively with symptomatic atopy among asthmatics and in the general population. It is, however, unclear whether sensitization to common allergens per se– as verified with positive skin prick tests – affects FENO in healthy individuals.


The authors applied the global operator of Drachman (1981) to the case of positron scattering from helium atoms. The global operator is identical to the usual delta function operator for exact wavefunctions and is expected to yield superior results in the case of approximate wavefunctions. This expectation is borne out in the present work.


The catalytic thermal decomposition of acid is a convenient and low cost method of deacidification,but its acid removal rate is low,so its industrialization application is restricted.Using magnesium oxide,zinc oxide,Mg-Al hydrotalcite,and H-ZSM-5 as the active components of the catalyst,the deacidification experiments were carried out.The results showed that Mg-Al hydrotalcite used as the active component of the catalyst possessed higher catalytic thermal decomposition activity for deacidification,and it was proved by the mechanism that Mg-Al hydrotalcite had catalytic decomposition function for oil acid.The catalysts obtained by different preparation processes were evaluated.The optimal preparation process of the catalyst was attained as follows: the spherical catalyst prepared by mechanical mixing method,Mg-Al hydrotalcite dosage 30% of the catalyst mass,activated alumina as the carrier,and calcination temperature 500 ℃.The feed oil samples before and after deacidification were analyzed by FT-IR.The results of FT-IR characterization indicated that the naphthenic acid in the oil after deacidification disappeared,which proved that Mg-Al hydrotalcite catalyst possessed good deacidification effect.


This paper proposes a new design approach to the currents controller of Voltage Source Converters (VSC) connected to the power grid. By developing a system model in the discrete domain and by using complex numbers, the proposed approach deals simultaneously with the cross coupling components of the currents model in the synchronous referenced frame and with the delay between the currents acquisition and the PWM actuation. The controller is easily tuned as the designer only needs to specify the required settling time. Robustness against grid filter parameters variation is also a characteristic of the proposed controller.


The growth of weeds among agricultural crops is a pest that can decrease agricultural production by 47-87%. The aims of this research is to compare organic and an organic fertilizer and compare mechanical and chemical weed and pest control. This research employed a mixed-method, observation, in-depth interviews, and life cycle assessment. The greenhouse gas emissions were released are organic fertilizer 1,87 x 10 -3 kg CO 2 eq/ha and an organic fertilizer 15 x 10 1 kg CO 2 eq/ha. Thereafter greenhouse gas emissions were released from mechanical control 1,87 x 10 -3 kg CO 2 eq/ha and chemical control 4,4 x 10 1 kg CO 2 eq/ha. The totally of greenhouse gas emissions was released from dryland paddy farming in management phase is 19,4 x 10 1 kg CO 2 eq/ha. Organic fertilizer more friendly than an organic fertilizer and mechanical control more friendly than chemical control. Mechanical control by farmers must be modified for the increase of effectiveness. The post-mechanical control should be those containing fruit and seed must be burned, meaning there will be not a longer any weed growth potential. Therefore, this mechanism will be able to realize potential production and sustainable dryland paddy farming.


Background: The first mysterious case of respiratory disorders came from Wuhan, Hubei Province. The media that became the source of transmission in this case is still not known for certain, this virus can be transmitted from human to human and has spread widely. People who are most at risk of contracting this disease are people who are in close contact with Covid-19 patients, including those who care for Covid-19 patients. Standard recommendations to prevent the spread of infection are through regular hand washing with soap and clean water, practicing cough and sneezing etiquette, avoiding direct contact with livestock and wild animals and social distancing with anyone showing symptoms of respiratory illness. Objective: increase the vigilance of the mosque congregation (women) regarding the transmission of covid-19 in the new normal era through health education, washing hands 6 steps during this pandemic is considered very necessary. Methods: Health education was carried out using lecture and discussion methods as well as monitoring success by observing mosque congregations (girls) in demonstrating 6 steps of hand washing. Results: The form of evaluation and achievement targets in this activity is to improve health status by increasing knowledge of Hand Washing 6 Steps to Increase Awareness related to Covid-19 Transmission in the New Normal Era. Conclusion: The indicator of success in the form of questions and answers at the end of the implementation session showed that most (85%) were able to answer questions smoothly and well.


The aim of the study was to describe the pattern of resistance mutations in human immunodeficiency virus type 1 (HIV‐1) infected patients experiencing their first protease inhibitor (PI) failure on nelfinavir (NFV)‐containing therapy. Earlier PI‐naïve patients (n = 172) with NFV‐containing therapy were therefore retrospectively studied. Plasma HIV RNA from 43 failing patients was sequenced. In addition, virus from the baseline was sequenced in 29 patients. Failure was defined as two consecutive measurements of viral load of >50 copies/ml after 6 months treatment. Subtyping was done in most patients (n = 118). At baseline, the V82A mutation was found in four PI‐naïve patients of whom two failed therapy exhibiting this mutation. At therapy failure, 17 of the 43 (40%) patients had primary PI mutations. In nine subjects, RTI‐mutations only were found and 17 patients had a wild‐type virus. Patients with primary PI and/or RTI mutations had a higher viral load at failure than those who failed with wild‐type virus. A surprisingly diverse pattern of primary PI mutations was seen: M46I (n = 7), D30N (n = 6), L90M (n = 5), and V82A (n = 4). Four patients exhibited more than one primary PI mutation. PI‐naïve patients in Sweden may harbor PI‐resistant virus and resistance testing should be considered before treatment. Patients who fail NFV may develop the M46I mutation, which has been related earlier to mainly other PI. The diverse pattern of the evolved PI‐mutations and the relative low occurrence of the D30N mutation in the material was unexpected and did not seem to be related to the viral subtype. J. Med.

Carrying out diversification management stratagem is an inevitable choice when an enterprise develops to a certain degree.The enterprise only can only find the chance and hold the scale,then can really play the actions for diversification management.


Domestic violence is a major social problem worldwide. In the United States, the failure of communities and police departments to intervene resulted in a push to adopt and implement pro and mandatory arrest policies for domestic violence. These policies have led to an unexpected increase in the number of arrests of women. Competing explanations have been offered. This paper describes the development of a system dynamics model of women arrested for domestic violence. Results suggest that these policies may have created or strengthened a crossover mechanism that shifts the risk of arrests in domestic violence cases from men to women. Model analysis demonstrates how the changing role of cooperation between advocates and police can help explain the trends in women arrests. Implications for research and policy are discussed.

The author conducted a questionnaire survey of language awareness in 358 students studying in Grades 8, 10, and 12 English classes in three rural and three urban schools in Nova Scotia. The main objectives of the study were to learn just how sensitive these students were to key aspects of language prior to any deliberate instruction in language awareness, to obtain new information about levels of natural language awareness as the basis for curriculum development, to uncover significant subject variables in relation to developing language awareness, and to clarify the theoretical distinction between "ordinary" and "critical" language awareness.


Nanocrystallines Co3O4 with the particle diameter of 3 nm are prepared and tested as active electrode material for an electrochemical supercapacitor. The results of characterization indicate that the grain size of this material is very small; the specific surface area is very high (192 m2/g); the distributions of pore diameter are desirable and effective; furthermore, the agglomeration problem among small particles was solved to a certain extent. The electrochemical tests show that the electrode prepared with the Co3O4 exhibits distinct characteristic of capacitance and very high specific capacitance of 365-401 F/g. Additionally, the main attribute of capacitance, namely supercapacitance, was also testified.


The Late Permian sedimentary environment in Xingmeng area has long been a topic of controversy. Most researchers believe it is continental deposit, while a few people hold that it had been a closed marine basin at the early stage, and then changed into a lacustrine basin. In order to settle down this dispute, the authors measured the section of Guandi in Linxi area and discovered large quantities of limestone lenses containing calcium algae, bryozoans and some other marine fossils. Limestone lenses were collected systemically, and their elements and carbon and oxygen isotopic compositions were analyzed. The results show that the limestone lenses are characterized by depletion of LREE relative to MREE and HREE, obvious positive Eu anomalies, minor positive La, Ce anomalies and lack of Gd and Y/Ho anomalies. Si O2 values are high, and Zr and REE have obvious positive correlation, suggesting a near-coastal deposition environment. The depositional water was derived from three sources, i.e., normal seawater, river or atmospheric precipitation and hydrothermal solution. The sedimentary sequence, the assemblages of fossils in the section and the composition of carbon and oxygen isotope in limestone also provide further support for the near-shore environment. In Late Permian, there was still a narrow marine basin with hydrothermal activity in the Xingmeng-Jilin area. The sea water circulation was probably blocked in the coastal area, which caused the domination of evaporation or river discharge in a short period, thus resulting in a substantial shift of carbon isotopes. However, the oxygen isotope excursion was caused mainly by diagenesis.

This paper describes a novel automated inspection process for tempered safety glass. The system is geared toward the European Community (EC) import regulations which are based on fragment count and dimensions in a fractured glass sample. The automation of this test presents two key challenges: image acquisition, and robust particle segmentation. The image acquisition must perform well both for clear and opaque glass. Opaque regions of glass are common in the American auto industry due to painted styling or adhesives (e.g. defroster cables). The system presented uses a multiple light source, reflected light imaging technique, rather than transmitted light imaging which is often used in manual versions of this inspection test. Segmentation of the glass fragments in the resulting images must produce clean and completely connected crack lines in order to compute the correct particle count. Processing must therefore be robust with respect to noise in the imaging process such as dust and glint on the glass. The system presented takes advantage of mathematical morphology algorithms, in particular the watershed algorithm, to perform robust preprocessing and segmentation. Example images and image segmentation results are shown for tempered safety glass which has been painted on the outside edges for styling purposes.

Development and validation of a multiplex, long quantitative PCR-based method to measure DNA adducts induced by chemotherapeutic agents in specific sequences, with clinical application potential


First of all, the three constant-envelope multiplex methods have been introduced: Interplex/CASM (Coherent Adaptive Subcarrier Modulation), Majority voting and POCET (Phase-Optimized Constant-Envelope Transmission). And then four signals multiplex has been simulated as an illustration using the three kinds of constant envelope multiplex techniques respectively. According to simulation analysis, the highest multiplex efficiency has reached -0.64dB when using POCET. And then the performance of three multiplex algorithms in band-limited systems has been simulated and analyzed. With the bandwidth limit, the multiple signal after constant-envelope multiplex cannot keep its envelope constant any more, which makes the multiple signal distort and brings crosstalk among sub signals. Therefore to study the constant-envelope multiplex techniques with bandwidth limit will become the important issue for the further research on navigation signal multiplex techniques.


Flash pyrolysis of a thin film of lead salt of 3-nitro-1,2,4-triazol-5-one was studied by T-jump/FTIR spectroscopy. The kinetics of the exothermic decomposition reaction was determined by the time-to-exotherm (tx) value derived from the control voltage traces of the Pt filament. The global Arrhenius activation energy Ea was 94.0 kJ·mol-1 and lnA was 20.5 for the flash pyrolysis of this compound at 500~540 K under 0.1 MPa Ar atmosphere. The corresponding Gibbs energy, entropy and enthalpy of the hypothetical activated process of exothermic decomposition reaction for the flash pyrolysis were determined approximately. The values determined herein could be used in evaluation of the thermal stability under rapid heating conditions and could be incorporated into steady combustion modelling.


Al/sub 0.48/In/sub 0.52/As/Ga/sub 1-x/In/sub x/As pseudomorphic HEMT's with very high gate and channel breakdown voltages were successfully fabricated. To improve the breakdown characteristics, graded pseudomorphic Ga/sub 1-x/In/sub x/As and Al/sub 0.2/In/sub 0.8/P were adopted as a channel and Schottky layer, respectively. Systematic studies reveal that the modification of the quantum-well channel by grading the composition considerably changes the channel breakdown (BV/sub ds/) and output conductance (g/sub 0/) characteristics. HEMT's with graded Ga/sub 1-x/In/sub x/As channel (x=0.7 to 0.6) exhibited improved BV/sub ds/ (11 V) and g/sub 0/ (40 mS/mm) compared with HEMT's with uniform composition (x=0.7) in the channel (BV/sub ds/=4 V and g/sub 0/=80 mS/mm).<<ETX>>

A number of k sets of light transmissive members are prepared, k being an integer of 2 or greater, where each set thereof may consist of a plurality of first light transmissive plates and a plurality of second light transmissive plates, and (K+1) third light transmissive plates having a greater thickness than those of the first and the second light transmissive plate. A composite plate member is produced by alternately arranging and bonding one set of the plurality of first light transmissive plates and the plurality of second light transmissive plates to each of the spaces between the (K+1) third light transmissive plates, and alternately arranging a plurality of polarization separating films and a plurality of reflecting films on each interface in the composite plate member. A block substrate having a light receiving surface and a light emitting surface is produced by cutting the composite plate member along a first section parallel to a surface inclining at a predetermined angle with the surface of the composite plate member, the light receiving and light emitting surfaces being parallel to the first section. The light receiving surface and the light emitting surface of the block substrate are polished, and k light transmissive blocks are produced from one block substrate by dividing the block substrate at the positions of the third light transmissive plates disposed inside the block substrate.


We present equations of state relating the phases and a three-dimensional phase diagram for ammonia with its solid, liquid, and vapor phases, based on fitted authentic experimental data and including recent information on the high-pressure solid phases. This presentation follows similar articles on carbon dioxide and water published in this Journal, where the basics of multiple-phase equilibria are described. Such an authentic diagram for ammonia has not been presented and may improve the understanding of its phase relationships. Interactive virtual 3D versions of these phase diagrams, programmed in Jmol, are also available. Since the phase data on ammonia has not been comprehensively collated in recent years, a chronological bibliography of relevant publications is included.


The BP algorithm with adaptive learning rate is analyzed and then sorted into two groups. A few existing BP algorithms with adaptive learning rate are presented of each class. At last, a kind of BP algorithm with adaptive learning rate is evaluated and compared with standard BP algorithm by XOR problem.


The method of forming the catheter of the inner coil layer comprises: preparing a hollow tubular catheter body is used as a substrate; production mandrel, the outer surface of the mandrel with a helical layer, is incompatible with the material of the hollow tubular outer surface of the substrate, the mandrel the size of the inner diameter of the helical layer is designed such that the hollow tubular substrate as the spiral outer diameter of the helical layer is less than or equal mandrel; mandrel placed inside of the hollow tubular substrate; by the action of heat, the hollow tubular substrate is coated helical layer on the mandrel, the mandrel helical layer height of the embedded depth of the hollow tubular substrate is less than or equal to the helical mandrel layer; mandrel from the hollow tubular substrate is removed so that the inner hollow tubular base helical layer is formed. Because the mandrel with a helical layer may be repeatedly used, costs are lower; while the catheter is formed of the inner coil layer is not introduce new substances, no increase in the risk of biological and structural risk of the catheter.


Gracilaria corticata J.Ag., anti-ulcer, antiobesity, anti-diabetic and anti-cancer activity. In the present study, methanolic extract of the red seaweed Gracilaria corticata J.Ag. (ME of G. corticata) at 200 and 400 mg/kg was screened for the activities: Anti-ulcer (Aspirin induced model), anti-obesity (Monosodium glutamate induced model), anti-diabetic (Alloxan induced model) on Wistar albino rats and anti-cancer (MTT assay) against Molt4 cell lines. ME of G. corticata showed significant (P < 0.05) dose dependent activities (400 > 200 mg/kg doses) except the anti-diabetic activity. This may prove helpful for developing new drugs from this red marine algae G. corticata for managing gastric ulcers, obesity, cancers and their associated complications. However further studies required to elucidate the exact mechanism of action and the structure of the secondary metabolites which are responsible for these activities for the development as potent anti-ulcer, anti-obesity and anti-cancer drugs.


The problem of wave-number selection by a ramp, i.e., a region smoothly matching sub- and supercritical domains, is considered within the framework of the cubic and quintic Ginzburg-Landau (GL) equations with a sign-changing overcriticality parameter. A local frequency is also allowed to be a smooth function of the spatial coordinate. For the cubic model, a unique value of the selected wave number is found by means of an asymptotic procedure valid when the imaginary parts of coefficients in the GL equation are small, while the group velocity is arbitrary. Under certain conditions, the wave number may lie outside the stability band, which is expected to give rise to a dynamical chaos


U.S. crude oil refinery utilization rates have steadily increased since oil price and allocation decontrol in 1981. The annual average atmospheric distillation utilization rate has increased from 68.6 percent of operable capacity in 1981 to 92.6 percent in 1994. The distillation utilization rate reached a peak of 96.4 percent in August 1994, the highest one-month average rate in over 20 years. This dramatic increase in refining capacity utilization has stimulated a growing interest in the ability of U.S. refineries to supply domestic requirements for finished petroleum products.


Throughout history, great nations have been built and great developmental strides attained, not by inchoate policies or untailored measures, but by well-articulated systematic policies of sustained development. For Africa, development policies and programmes must be circumscribed by a clear understanding of the crucial role of the forces of cultural and economic security on the development process. Given the giant leap in economic, political and social development by other developing continents vis-a-vis Africa, it has become imperative to ponder these questions: Do African cultures encumber or foster Africa's economic development? Is Africa's leadership challenge rooted in her cultural heritage? Despite huge natural resources and potentials, the crisis of Africa's poverty and underdevelopment juxtaposing corrupt and inept national leadership warrants a reassessment of the trajectories of Africa's development. Indigenous peoples' cultures and their knowledge systems have had a determinative effect on the lives, socioeconomic development trajectory and pace of development of Africans. Yet, these cultures and their knowledge systems have been largely misunderstood, incompletely developed or even ignored by conventional models of economic development. Understanding the crucial role of the dynamics of culture and security in economic development of nation states is important, especially given global commitment to democracy, human rights and pluralism (political, religious and cultural). This paper identifies the cultural challenges that cause the success or failure of national development in Africa. It prescribes the synthesis and remodelling of the apparatuses of cultural and economic security in the bid to foster economic development in the region.

"Bushido: The Soul of Japan" composed by Nitobe Inazo has crucial influence to Europe, America and Japan. By now there are many researches on "Bushido," however; there is very tiny literary research or ideological research into the article itself. The ultimate and core purpose of this thesis, therefore, is to explore to the significance of the creation of "Bushido: The Soul of Japan," which is divided into two parts tracing the ideological ordeals that the author Nitobe had experienced before he wrote this book. The focus of Part I tries to depict and clarify the spiritual ordeals and the derived spiritual dilemma the author of "Bushido" encountered, in which firstly we may realize that, generally through the whole life of Nitobe, his professor time at Sapporo Agricultural College was full of fresh experience and distress. Secondly, further observation is at the consecutive ideological controversy after the promulgation of "Kyoikutyokugo" to know his miserable plight as a Christian under the criticism that the doctrine of Christianity was not suitable to national education policy. Hence, Nitobe, as a professor who had faith in Christianity, was forced to face a problem which was confrontation and tension between the doctrine or spirit of Christianity and what is for a long time in Japan called as the East Confucianism, which thus appears the initial spiritual background and critical mind of the author.


The Right to Reconcile Family Life and Work: A Case Study of How Individual Freedom Relates to Social Expectations ABSTRACT: In Italy, the right to reconcile one's professional life with one's family life was declared in 2000, in a very sweeping and detailed law (N° 53) that comes under the heading of the social policies sustained for some time by the European institutions, whose aim is to enact a series of measures, including paternity leave, to achieve a better balanced participation of women and men, both in the working world and in the activities involved in caring for the family. As it is cited in European document mission statements in particular, the right of reconciliation is dual in nature: it is both a social right and an individual right of freedom, as its application ought to enable women and men to live out their personal relationships in both their public and their private lives. Moreover, insofar as it concerns the relations between social caregivers and social beneficiaries (between parents and their children, for example, but also the older or disabled members of the family), it can also be included under the heading of rights of relationship. The article underscores the almost magical nature of the right of reconciliation, which aims to cater for a very wide range of very different expectations, highlighting the risk that it may be used to transform social problems into individualised legal problems. Specific attention is then paid to its subjective dimension, as a right in everyday life, when elements of conflict become relevant, as its enactment calls for a rather radical redefinition of gender roles in housework and in caring.


Abstract The term 'digital twin' refers to a virtual simulation/model (virtual twin) of a physical plant or object (physical twin), where data flows between the virtual and physical twins. A digital twin can be used for different purposes, such as process optimisation/control, design, training, and maintenance/service. This manuscript found an increasing number of simulation and modelling publications in literature year on year, which illustrates the current trend towards implementing digital twins in a broad range of process engineering applications. A targeted literature review into the area found several commercial off-the-shelf software solutions (COTS) for different industrial applications providing the necessary flexibility to analyse a broad range of industries. However, most of the process modelling software is designed for petroleum and fine chemicals processes. There is still a need for software solutions that can model a broader range of applications. While most of the software found was licensed, open source process modelling software was also available. There is a lack of independent research into the accuracy of these software solutions. The literature review also found that 37% of the research based on process simulations is carried out to improve energy efficiencies. In comparison, 27% of the research found Decarbonization to be a secondary "added" benefit. It can be concluded that digital twins are ideally suited for driving energy efficiency improvements and decarbonisation goals. However, none of the COTS identified in the literature meets all the requirements for a digital twin. A solution to this problem is to create a layered digital twin, combining and interfacing different tools to accomplish a visually similar, self-optimising, self-learning virtual plant.


The indica-japonica character of a novel rice germplasm Yihui 1577 was identified based on six agronomic traits(lemma hair,pheno reaction,internode length between the first and second nachiees,the hull color at heading,leaf hair and grain shape) with the morphological index method founded by Mr Cheng.The results showed that Yihui 1577 belongs to japonicalinous restorer line.The yield combination ability analysis of Yihui 1577 made by not complete dual crossing with 4 CMS lines and 6 restore lines indicated that general combination ability effect value of Yihui 1577 was 0.226 and that of Minghui 63 was-0.113,the former was superior to the latter.


The results of the debates of the authors are not easy solutions for the problems that arise from the right of freedom of religion. This chapter pays attention to specific items that were in debate because these are issues that challenge the authors reflection on freedom of religion and the role of governments and religions in their mutual relation. First of all, it is clear that freedom of religion is a basic right. It is a challenge for governments to understand what religion does to people. It is a challenge for politicians to understand how fundamental religion and its expressions function. It is also a challenge to understand that any - as such - futile aspect of religious expressions can become a shibboleth. It is a dilemma for lawmakers to balance between freedom of religion and raising conflicts due to limitations because these limitations restrict human dignity of the believers.Keywords: freedom of religion; government; lawmakers; politicians


We assessed characteristics of atrial and ventricular activity from the ECG for predicting the oflset of atrial fibrillation for the 2004 PhysioNet/Computers in Cardiology Challenge. Seven parameters were analysed with five based on the statistical characteristics of the RR interval (mean, standard deviation, skewness, kurtosis and median beat-to-beat change), and fibrillation frequency and atrial signal amplitude. The power of the parameters to predict termination of the arrhythmia was assessed individually and in combination using linear discriminant analysis ( D A ) and a?t$cial neural network (ANN) techniques. Fibrillation fiequency with a threshold value of 5.55 Hz was able to idenrify 10/10 learning set records which terminated immediately (T) and 8/10 of non-terminating records (N) and was the best of the individual parameters. Classifcations for the test set for event 1 of the challenge for algorithms based on fibrillation frequency alone, LDA and ANN received scores of 24/30, 18/30 and 23/30 respectively. Low jibrillation frequency is an indicator of spontaneous termination of atrial fibrillation.


A full asymptotic series for low eigenvalues and eigenfunctions of a stationary Schrodinger operator with a nondegenerate well was constructed in [29]. This allowed us to describe the tunneling effect for a potential with two or more identical wells with sufficient accuracy. The procedure is described in the following discussion. Some formulae are obtained and corresponding problems are discussed.


Unmanned Aerial Vehicles (UAVs) are required to have Autonomous Collision Avoidance System (ACAS) to resolve conflicts, especially when flying in the National Airspace System (NAS). This paper focused on the non-cooperative concept for avoidance, where UAVs face rogue obstacle that does not cooperatively share their flight data, nor they follows the rule of the air. UAVswill rely on its on-board sensor for avoidance, in space and time range that is limited. The limitation make the entire process of sense, detect, and avoid (SDA) mostly not applicable, and sense and avoid (SA) manner is more preferable and safe. A method called SA-VO that extend the use of the known Velocity Obstacle (VO-) method is introduce to handle the problem. The method produce more efficient avoidance in the non-cooperative space than SA manner of avoidance, without fully run the SDA process. Probability of collision map based on ranges of obstacle range of positions and velocity is predefine to replace the detection part of SDA. The method is then tested using simulations of encounters between UAV and an obstacle. The simulations show that SA-VO can be a middle ground between the SDA and SA manner of avoidance.


The question whether hidden weld in unstiffened overlapped CHS KK-joints is welded or not is not clearly metioned in current code for design of steel structures(GB50017-2003).This paper mainly analyzes the influence of chord-to-brace diameter ratio β,diameter-to-ply ratio γ and brace-to-chord ply ratio τ on the ultimate bearing capacity of the joints with the hidden weld welded in two different ways.the influence of welded and non-welded hidden welds of the joints on hysteretic property under low frequency loading is analyzed,and hystertic loops of the joints are obtained by using the ANSYS finite element method.The hidden weld of the joints,no matter which is same side brace or opposite brace,only has slight influence on the failure modes and limit capacity of the joints.Hysteretic property of the joints in which the hidden weld is non-welded is much better than the welded,so in project the joints with the hidden weld can be non-welded.


The purpose of this study was to investigate the response of sugar maple borer, Glycobius speciosus (Say) (Coleoptera: Cerambycidae), to crown-damaged sugar maple in three northern hardwood stands following a major icing event. The objective was to determine whether incidence of borer damage in the ten-year period following this major abiotic stress was greater than incidence during the ten-year period prior to the storm, and to evaluate whether silvicultural re-habilitation of these stands following the storm affected incidence of damage. In neither re-habilitated nor untreated plots was incidence greater post-storm.


Soil and water conservation programs have been institutionalized and standardized since the end of 20th century,but lots of practitioners make some mistakes when they work on the soil and water conservation program between construction projects and production and construction projects.There are many differences in the soil and water conservation program between construction projects and production and construction projects.Based on the year's experience of making the program,we summarized the similarities and differences between construction projects and production and construction projects in view of service life,soil loss prediction,soil loss prevention target,and other aspects.This work may be helpful to avoid the mistakes in making soil and water conservation programs.


A case of clear cell chondrosarcoma located in the acetabulum was reported. The patient was a 39 years old woman who had right pelvic pain. Microscopic examination revealed that the tumor cells have a centrally placed vesicular nucleus with a clear cytoplasm. Because of its rarity and its frequent confusion with benign tumors as well as other more agressive osseous malign tumors, clear cell chondrosarcoma was discussed with the review of the literature.
