It is very important for experiment teaching in the entire teaching of high engineering institutions,but,in a long period of time,the backward teaching instrument and teaching method have restricted the improvement of teaching quality in large degree.Virtual instrument technology applied in experimental teaching work in high education supplies a new way to improving experimental condition in high education.And virtual oscilloscope based LabVIEW is build to explain the application in experiment teaching.


Summary Four of five 'hairy' Wiltshire lambs had fibre type arrays (as defined by Dry, 1965) of Plateau (P0 and P1) type, whereas in five 'woolly' lambs there was only one Plateau (P3) array, the arrays of the remaining lambs being Ravine or Saddle. In terms of Dry's theory that the severity of pre-natal check determines persistence of wool growth in adults, it appears that the amount of checking in these Saddle and Ravine arrays was insufficient to prevent the casting of the adult coat.


The contact areas (on a molecular scale) between aqueous solutions and leaf surfaces have been measured in order to obtain information on the actual areas effective in cuticular transport. For this purpose, monolayer adsorption of pentaclilorophenol (PCP) was used on leaf surfaces and on artificial surfaces. The adsorption isotherms were analysed according to the Brunauer-Emmett and Teller (BET) formalism leading to BET constants and actual contact areas between the aqueous PCP solution and the surfaces. BET constants ranged from 4 to 11, with an arithmetic mean of 6.5. No relationship was found between the chemical composition of the surface waxes and the BET constants, and there were no significant differences between BET constants measured using isolated waxes or intact leaves


To speed up file access speed,object-based storage file system introduces the client caching mechanism,which also brought the problem of the cached data consistency.When multi-clients try to access to shared files,given the delay,heavy load of network and server,too much network consumption and other issues of cache update strategy,object-based storage Lustre file system achieved an improved collaborative cache coherency strategy.The experimental results show that improved cache update strategy not only can guarantee the consistency of cached data but also reduce interactions between client and server,and the access latency and the system I/O performance is improved.


The article makes explicit and analyzes the participatory methodologies of exhibition curators in the context of the Escola Livre de Artes Arena da Cultura. It is possible to present reflections on the experience lived as a Teacher at that School, located in Belo Horizonte, capital of Minas Gerais (BH-MG), in the second semester of 2019. Initially I present the ELA-Arena guidelines, and then I bring bases and discussions around this work. In addition to conclusions, I intend that the article brings good examples of the possibilities of democratization and cultural accessibility that have occurred at the local level.

Keywords: participatory methodologies; curatorship; cultural inclusion.


A non-zero $\mathbb{F}$-valued $\mathbb{F}$-linear map on a finite dimensional $\mathbb{F}$-algebra is called an $\mathbb{F}$-valued trace if its kernel does not contain any non-zero ideals. However, given an $\mathbb{F}$-algebra such a map may not always exist. We find an infinite class of finite-dimensional commutative $\mathbb{F}$-algebras which admit an $\mathbb{F}$-valued trace. In fact, in these cases, we explicitly construct a trace map. The existence of an $\mathbb{F}$-valued trace on a finite dimensional commutative $\mathbb{F}$-algebra induces a non-degenerate bilinear form on the $\mathbb{F}$-algebra which may be helpful both theoretically and computationally. In this article, we suggest a couple of applications of an $\mathbb{F}$-valued trace map of an $\mathbb{F}$-algebra to algebraic coding theory.


Extended Abstract Reactor coolant enters at cold-leg nozzles, goes down along the down-comer, changes flow direction and goes up passing through core region, and then exits hot-leg nozzles under normal operation of typical PWRs (Pressurized Water Reactors). Since temperature variance caused by inertia resistance and decay heat as well as pressure drop due to fuel assemblies are important and complicated in the core region, lots of efforts have been devoted to relevant design and evaluation. Even if narrow down to CFD analyses, however, it is not easy to simulate large and complex shapes of the fuel assemblies and their features as they are. To resolve this issue, a number of researchers have been adopted alternative porous media. For instance, Cheng et al. [1] investigated thermal hydraulic characteristics subjected to asymmetric conditions. Kutuk et al. [2] examined flow mixing characteristics for full-loop and three-loop cases. Kansal et al. [3] analysed temperature distributions in vertical calandria vessel with spatial and uniform distribution of volumetric heat generation. The objectives of this study are to address thermal hydraulic characteristics in the core region and to quantify their dependency. Reactor vessel with internals were considered and an optimized CFD model was developed for a 600MWe reactor. Parametric analyses were carried out by assigning temperatures of 286°C at inlet and 320°C at outlet with a pressure of 15.5 MPa. Not only uniform heat generation rate was applied as a source but also porosity, permeability and pressure drop coefficient were set to fuel assemblies bulk model. Resulting pressure and temperature distributions were compared. In particular, effects of pressure drop, heat generation and their interaction were discussed. Effectiveness of porous media and influence of different flow paths to reflect design change were also examined. Moreover, application of the CFD analysis results to thermal and structural analyses for subsequent studies will be introduced.


Growth and pigment responses to different levels of solar radiation with or without ultraviolet (UV)-B component were investigated in Antarctic rhodophytes, Kallymenia antarctica and Palmaria decipiens, collected around King George Island during the summer of 2000. In K. antarctica specific growth rate, based on thallus area or fresh weight, decreased with increasing solar irradiances while P. decipiens were relatively insensitive to the effects of light. It is noticeable that the presence or absence of UV-B had no significant effect on growth for either species. However, K. antarctica showed a more pronounced reduction in chlorophyll (Chl a) concentrations at higher irradiances in the presence of UV-B. In P. decipiens, Chl a concentrations did not differ despite radiation level fluctuations being lower albeit than initial measurements. Thallus thickness was greater in K. antarctica than in P. decipiens. There were higher relative amounts of UV-absorbing pigments (UVAPs) in P. decipiens than in K, antarctica. The single absorbance peak obtained from the methanol extracts was resolved into three (316,332 and 346nm) in K. antarctica and four peaks (315,326,333 and 349 nm) in Palmaria as a result of the fourth-derivative. After 7 days exposure to solar radiation, the amount of UVAPs in K. antarctica was significantly reduced to a similar degree at all light levels, whereas that of P. decipiens remained unchanged except at 5% of surface irradiance. High performance liquid chromatography (HPLC) analysis of purified extracts indicated that P. decipiens possesses porphyra-334 in addition to three other mycosporine-like anlino acids (MAAs; asterina-330, palythine, shinorine), which are commonly present in K. antarctica. Significantly lower tolerance of K. antarctica to high levels of solar radiation may be connected with its usual absence in the eulittoral, while the active growth and elastic pigment responses of P. decipiens over a wide range of solar irradiance levels up to full sunlight seems to correspond well with its wide vertical distribution from rock pools down to 25-30m.


Abstract : Occasionally, the extraction of an impacted tooth provides a clinical challenge for an oral surgeon. Any tooth may be impacted, but third molars and maxillary cuspids are most frequently encountered followed by premolars and supernumerary teeth. Various surveys have reported the rate and frequency of impacted teeth. Impactions can occur because of malpositioning of the tooth bud or obstruction in the path of eruption. Two unusual cases of impacted permanent first molars are described. The importance of panoramic radiographs in the identification of such anomalously placed teeth is stressed. (Author)

Objective To discuss the feasibility and effects of cemented artificial bipolar arthroplasty for senile patients with femoral intertrochanteric instable fractures. Methods From January 2004 to June 2008,46 aged cases with femoral intertrochanteric instable fractures were cured with cemented artificial bipolar arthroplasty. According to improving-classfication of Evans,there were 19 cases with type Ⅲfractures and 27 cases with type Ⅳ fractures. Results All cases were successfully operated. The surgery time was 50-90 (68.00 ±20.43) minutes. Bleeding volume was 160-600 (210.00 ±40.26) ml. The time in hospital was 16-26 (19.30 ± 4.56) days. All cases were retrospectively reviewed for 6-39 (17.10 ± 4.33)months. Three cases died of other diseases, 43 cases were graded by the system of Harris. The Harris scale was 70-94 (86.70 ±5.16) scores,and the choiceness rate was 90.7%(39/43). No dislocation,loosening,subsidence and late infection occurred in all the implants. Conclusions Cemented artificial bipolar arthroplasty has good advantages of reduced laying up period and few complications. The short-term outcome is satisfactory.

Mutation Testing (MT) is a test quality assessment technique that creates mutants by injecting artificial faults into the system and evaluating the ability of tests to distinguish these mutants. We focus on MT for safety-critical Timed Automata (TA). MT is prone to equivalent and duplicate mutants, the former having the same behaviour as the original system and the latter other mutants. Such mutants bring no value and induce useless test case executions. We propose MUPPAAL, a tool that: (1) offers a new operator reducing the occurrence of mutant duplicates; (2) an efficient bisimulation algorithm removing remaining duplicates; (3) leverages existing equivalence-avoiding mutation operators. Our experiments on four UPPAAL case studies indicate that duplicates represent up to 32% of all mutants and that the MUPPAAL bisimulation algorithm can identify them more than 99% of the time.

Ecological garden is a trend of the urban greenary in morden cities.Greenland construction is very important for enviromental protection in factory districts with a higher pollutant concentration.Developing factory green open space with ecological garden theory is becoming an effective way.According to the thought of ecological garden,several problems were discussed based on the case of Baosteel.


In this paper we present a model of Quantum Associative Memory which can be a helpful tool for physicians without experience or laboratory facilities, for the diagnosis of four tropical diseases (malaria, typhoid fever, yellow fever and dengue) which have similar symptoms. The memory can distinguish single infection from multi-infection. The algorithm used for Quantum Associative Memory is an improve model of original algorithm made by Ventura for Quantum Associative Memory. From the simulation results given, it appears that the efficiency of recognition is good when a particular symptom of a disease with a similar symptoms are inserted.

Background: Von Willebrand disease (vWD) is the most common inherited bleeding disorder with a reported prevalence of 1% in epidemiological studies and symptomatic prevalence of 1 in 10,000.
 Pregnancy in vWD is associated with increased bleeding risk particularly postpartum hemorrhage. Treatment options include desmopressin acetate (DDAVP), plasma derived factor concentrates and antifibrinolytic agents. Human Recombinant von Willebrand factor (vWF) (Vonvendi®) has been approved in the United States for on demand treatment and perioperative management of adults with vWD. It has been shown to maintain sustained levels of VWF activity but requires co-administration with FVIII to achieve adequate FVIII levels. Recombinant VWF is an option for patients who refuse blood for religious reasons.
 Case: Here we describe a 39 year old patient in her third pregnancy who is a Jehovah's Witness. Consent was obtained from the patient for this report. She was initially diagnosed with von Willebrand`s disease at the age of six, when she had hematuria. At the age of 11, with menarche, she had significant menorrhagia resulting in symptomatic anemia, a reduction in her hemoglobin concentration to 44 g/L, requiring uterine artery embolization. She was placed on an oral contraceptive pill for menorrhagia. She used DDAVP for trauma induced injury. Her first pregnancy resulted in spontaneous abortion. She required a D&C and DDAVP was used. Prior to delivery of the second pregnancy DDAVP was used but she had postpartum hemorrhage, requiring additional dosing of DDAVP and uterine artery embolization.
 In the current pregnancy, aPTT was 36.4 seconds with normal PT and platelet count and blood group O. At 15 weeks' gestational age, VWF antigen (ACL TOP 700 -IL HemosIL) was 0.11 units/ml (normal range for blood group O 0.45-1.5 unit/ml), ristocetin cofactor (ACL TOP 700 -IL HemosIL), 0.09 units/ml (normal range 0.48-2.0 units/ml for blood group O), and FVIII level (Sysmex CS5100 -Dade Actin FS) 0.09 units/ml (normal range 0.58-1.9 units/ml). Factor levels at 23 weeks' gestation 1 hour following DDAVP were FVIII 1.05 units/ml, VWF antigen 0.5 units/ mL, and ristocetin cofactor 0.52 units/ml. She was willing to accept recombinant factor concentrates only.
 Results: She had an elective admission for induction of labor at 37 weeks but proceeded to Cesarean Section due to non-progression of labor. Her PTT on admission was 40 seconds with VWF antigen of 0.11 units/ml, VWF activity < 0.07 units/ml and FVIII 0.13 units/ml. The Table describes her levels following the administration of recombinant vWF. She was administered Vonvendi® on a planned dose of 40 IU/kg Xynta® and rFVIII 30 IU/kg to increase factor levels to more than 50%; 60-min following infusions vWF : RCo was 0.64 U/ml with FVIII 0.79 U/ml. The Cesarean section was performed under spinal anesthesia without complications. Tranexamic acid was used intravenously before the delivery of the neonate and continued for first two days and then changed to oral dose.
 Target levels were achieved over the 5 days after delivery with the current regimen. She experienced a transient hypersensitivity reaction with urticaria and dyspepsia after the third dose of Vonvendi®. She did not have significant bleeding. Her hemoglobin concentration remained stable at 120 g/L throughout her inpatient stay.
 The neonate did not have bleeding with delivery but was found to have VWF antigen of 0.11 U /ml, VWF activity of 0.07 U/ml and FVIII of 0.16 U/ml. Genetic analysis of the mutation associated with her vWD is in progress.
 Conclusion: The use of rvWF and rVIII resulted in adequate hemostasis peripartum. Further prospective data are required to reaffirm the safety and dosing of rvWF for peripartum management of patients with vWD who require intervention.

We investigate the effect of various amounts of Ag and Cu solute atoms on the self-diffusivity of Sn in the (101) symmetric tilt βSn grain boundary. Using molecular dynamics (MD) simulations over a temperature range of 300K to 450K, we show that both Ag and Cu decrease the grain boundary self-diffusivity of Sn, as the amount of solute in the interface increases. Additionally, the presence of Ag at the grain boundary interface causes a greater reduction in the self-diffusivity of Sn when compared to Cu. We also analyze the solute effect on the diffusive width of the interface and find that low concentrations of both Ag and Cu shrink the width relative to the pure βSn interface.


Point-of-care apparatus for hepatitis virus detection require simple and easy-to-use processing steps and have the same diagnostic capability as the central laboratory. However, the lack of automated and efficent methods for HBV sample-to-answer detection include serum separation and complete pre-storage of reagents has been developed. We developed an au-tomated sample-to-answer disc for rapid hepatitis B virus detection from whole blood based on a double rotation axes cen-trifugal microfluidic platform (DRA-CMP). The disc with complete pre-sorage of reagents features fully automated and in-tegrated serum separation from whole blood, magnetic bead based DNA extraction, aliquoting of the nucleic acid, real-time PCR. Employing a laser diode for sequential release of prestoraged liquid reagents. Processing merely requires manual load-ing of the sample into the disc. We demonstrate successful sample-to-answer detecion of HBV in a 500 μL whole blood sample with sample concentrations down to 102 copies/mL. The total time of the whole detection from sample-to-result is about 48min. The disc provides a user-friendly molecular diagnostic system for rapid analysis of hepatitis B virus without demanding complicated laboratory instrument and major manual operation time. Overall, the results indicated that the de-veloped disc could be used for HBV molecular diagnosis.


Background Some patients with idiopathic pulmonary fibrosis (IPF) must be hospitalized because of heart failure (HF), including HF with preserved ejection fraction (HFpEF) and HF with reduced EF (HFrEF). The association between IPF and HF has not been clarified. We retrospectively investigated the clinical features and outcomes of patients with IPF who required nonelective hospitalization because of HF. Methods We examined data from IPF patients who required nonelective hospitalization for HF at the Kindai University Hospital from January 2008 to December 2018. We divided the patients into 3 groups: those with HFpEF without elevated right ventricular systolic pressure (RVSP), those with HFpEF and elevated RVSP, and those with HFrEF. The recurrence rates of HF after discharge and the 30- and 90-day mortality rates of the patients were evaluated. Results During the study period, 37 patients with IPF required hospitalization because of HF. Among the 34 patients included in the study, 17 (50.0%) were diagnosed with HFpEF without elevated RVSP, 11 (32.3%) with HFpEF and elevated RVSP, and 6 (17.6%) with HFrEF. Patients with HFrEF had significantly higher values for B-type natriuretic peptide (BNP) and left ventricular (LV) end-systolic and end-diastolic diameters than patients with the 2 types of HFpEF (BNP: P = 0.01 and P = 0.0004, LV end-systolic diameter: P <0.0001 and P <0.0001, and LV end-diastolic diameter: P = 0.01 and P = 0.0004, respectively). Notably, the difference between the LVEFs of the patients with 2 types of HFpEF was not significant. The patients with HFpEF without elevated RVSP had the lowest 30- and 90-day mortality rates (0%, P = 0.02 and 11.7%, P = 0.11, respectively). Conclusions Among patients with IPF, HFpEF without elevated RVSP was the most common type of HF that required hospitalization. Patients with HFpEF without elevated RVSP survived longer than the patients with the other 2 types of HF.

Five hundred forty-four unselected patients were examined by a radiologist as to the presence or absence of coronary artery calcification. The overall prevalence of coronary calcification was 20% and there was a definite increase in the prevalence of the finding with increasing age. A comparison of 94 patients with coronary calcification with a matched control group without calcification indicated that the prevalence of symptomatic ischemic heart disease in the group with calcification was approximately twice that of the control group. The correlation was even more significant when the degree of calcification was moderate or severe.It is concluded that cardiac fluoroscopy with image intensification is a useful supplementary tool in the clinical evaluation of patients suspected of having coronary artery disease. It can be performed easily and imposes no risk to the patient.

Corneal sensitivity was measured over a 28 day period in 3 groups of subjects-- females females taking oral contraceptives (OC) and males--to determine variations of the corneal touch threshold of young women during the menstrual cycle. As compared to the rest of the cycle corneal sensitivity was reduced markedly during the premenstruum and abo ut the time of menstruation. Discernible changes in corneal sensitivity were absent among women taking OCs and men. Because these changes were absent among OC users and men it is suggested that these results may be associated with generalized edema induced during the premenstruum.


Lip recognition is the process by which a computer learns the changes in dynamic lip image sequence of the speaker's lips to recognize the content of the language spoken by the speaker. Lip recognition technology is widely adopted in the fields of national public safety protection, medical correction, etc. Most of the current research uses deep learning for lip recognition, however, in order to achieve high recognition rates, the network models for lip recognition are getting larger and larger, which are difficult to deploy to mobile devices. Therefore, in this paper, we optimize and improve the traditional MobileNet network to address the above problems, and propose a more lightweight FD-MobileNet network, and use the combination of FD-MobileNet network and GRU network to recognize the two-dimensional image features and temporal features of lips. FD-MobileNet can extract the two-dimensional features of images, and GRU network can learn the action changes between sequences. Based on the advantages of these two networks, we propose a combination of FD-MobileNet and GRU for lip recognition. We analyze the performance of the model by recording the change curve of loss function, the performance of common models in self-made datasets and the lip shape difference of words. The result shows that FD-MobileNet + GRU network model possesses the best effect for lip recognition. (Abstract)


Abstract : An over-the-horizon (OTH) radar uses ionospheric reflection of high- frequency radio waves to propagate to areas far beyond the normal radar horizon. Two principle probabilities are associated with an OTH radar; the probability of successfully propagating to a given region via the ionosphere and probability of detecting a target in sea clutter, given that propagation occurred. A particular radar system was examined and tables of probabilities were generated for various ionospheric and target parameters. An example illustrates the method of combining these probabilities to obtain a composite probability of detection. The probability of propagating was calculated by a computer program that used radar parameters, the ionospheric parameters, the geographical location, and the time of day and year as inputs. The probability of detection involved a computer implementation of the radar range equation.


Scholarly opinion differs on the number of scientific traditions that developed in the history of mankind. Frits Staal is of the opinion that there are three such traditions: the West Eurasian tradition wich includes the European and Islamic scientific traditions, the Indian tradition and the Chinese tradition. The Indian cultural tradition, as the Greek, and to the exclusion of the Chinese, is characterized by the accentuation of formal logic. This made some scholars claim that only two rational traditions can be differentiated : the Western and the Indian. We further may not overlook the impact of culmtural (philosophical) borrowings in genuine developments. Some scholars have claimed that, e.g., Greek philosophy is indebted to Indian philosophy. Richard Garbe ascribe a definite Indian influence to Pythagoras via way of Persia. Jean Pryluski has laid emphasis on the Iranian borrowings in both the Greek and the Indian culture. This would practically reduce the number of scientific traditions to two : the Indo-Greek tradition and the Chinese tradition. For the Chinese tradition, we further have to take the impact of Indian buddhism into account.


In numerous parts of the country, Dalit Muslim community continues to lag behind other socio-religious categories in socio-economic and educational development. The condition of this community is dreadful with regard to educational attainment, income, employment in public sector, access to healthcare and other infrastructures, and there is a disproportionately high share of community members in prisons. Identity stereotyping, communal violence, ghettoisation etc. are other major issues which these community faces. Among others, the deprivation of community has been a result of their exclusion from important spheres of socio-economic decision making, lack of political empowerment, discrimination, frequent occurrence of communal violence etc. The Sachar Committee Report (2006) highlights most of these issues and deprivations which the community faces across almost all the states of India.

Nanoscience is an emerging field of research in the last decades. Amongst other approaches like ball milling, ablation processes and various vapor deposition techniques, wet chemical approaches are one very prospering way to synthesize nanocrystals. The colloid chemical approach is dominated by surface coordinating ligands, which allow controlling size and shape of the resulting nanoparticles with extreme accuracy. The most fascinating point about nanoscale materials is that their properties can differ tremendously from those of the respective bulk materials. These properties are typically affected not only by size and composition of the nanoparticles but also by their shape. This thesis summarizes the results of 20 original publications which are covering three closely connected aspects of modern colloidal nanochemistry. The chapters included are described in the following:  Chapter one gives an overview over the colloidal synthesis of nanocrystals as well as their main properties which are relevant for this thesis. Hence, important synthesis and growth parameters are discussed. The size quantization effect in semiconducting nanoparticles and the localized surface plasmon resonance effect in conductive nanoparticles are explained in depth.  Chapter two of this thesis deals with different aspects of shape control of colloidal nanoparticles. The advanced shape control developed in the various original publications in chapter two shows how far beyond simple (quasi)spherical nanoparticles colloid chemical synthesis can go today. A variety of differently shaped nanoparticles like rods, branched structures but also partially hollow or concave nanoparticles are introduced. All of them could be synthesized with very low degrees of polydispersity of the particle ensembles.  Chapter three investigates cation exchange reactions with colloidal nanocrystals which are versatile approaches for composition control in these systems. These ion exchange reactions can either fully or also partially transform nanocrystals from one material to another without changing size or shape of the starting particles.  Chapter four deals with property control in colloidal nanocrystals with a specific focus on nanoparticles with localized surface plasmon resonances in the near infrared spectral region. Here, nanoparticles from so-called degenerately doped materials are introduced as plasmonic materials which are a promising alternative for the traditional plasmonic noble metal nanoparticles.  The thesis is finished by a conclusion and an outlook at future perspectives of colloid chemical nanoparticle synthesis.


As student activism continues to roil campuses, concerns have arisen about the mental health costs associated with activist-oriented civic engagement. Drawing on in-depth interviews with 42 self-identifying student activists from across the United States, this study examines how activists describe the impact of their activism on their mental health. While just under one third of the respondents perceived a positive effect, 60% of the respondents noted adverse consequences to their psychological well-being. Nevertheless, these respondents remained committed to continuing their activism. Four factors surfaced in activists' reflections on their mental health, which, while not responsible for positive mental health outcomes, did help offset the stress, exhaustion, and guilt associated with activism. These four factors included social capital or connection to others, a sense of purpose, effecting change, and self-care and collective care. Respondents credited these factors with helping them to sustain the emotionally and physically difficult work of activism. Implications for higher education policy and practice are discussed.


This chapter investigates the the differences between Sefer Ḥasidim I (sections 1–152) and Sefer Ḥasidim. No less striking than the absence of retson ha-Borè (the Will of the Creator), asceticism, and other defining themes of the Pietist movement is the parallel absence in SH I of exempla, which abound in the other sections of Sefer Ḥasidim. Over the course of time, different editors appended SH I to various collections of material of Sefer Ḥasidim, always taking care that SH I opened the collection, ensuring that the reader would first encounter not the startling tenets of Ḥasidei Ashkenaz but rather page after page of conventional pietistic discourse on love of God, fear of God, humility, and so on. It is remarkable to what extent SH I and those passages in Sefer Ḥasidim that were in the spirit of SH I shaped the historical image of Ḥasidei Ashkenaz. Study of the influence of Sefer Ḥasidim on the subsequent literature of Ashkenaz, whether halakhic or ethical, shows that not only were the new ritual world of retson ha-Borè or the book's radical social teachings wholly without influence, but also that they went literally unnoted.

Present research focused on context-aware computing in service provisioning is very common but little in personalized service for users. In the same way, the user interest model of handheld devices in the personalized context-aware service is also rare. Relies on the personality user model in PC to study a user interest model adding context information on the handheld device tentatively, and gives detail description in the design process through simulation experiments, the result of the experiments show its validity, also gives outlook on research of the future of user model of handheld devices.


Continuous living cover's (CLC) perennial and winter annual crop varieties present a novel opportunity to increase the diversity and resiliency of agroecological systems in the Mid-Continent of North America. However, transforming the predominant agri-food regime remains a complex and daunting undertaking. In the face of such complexity, a recent body of literature highlights the particular importance of intermediaries in facilitating sustainability transition processes, which CLC agriculture's proponents can draw upon. Intermediaries can be defined as actors or organizations that positively influence sustainability transition processes by linking diverse entities, networks, institutions, activities and their related skills, knowledges, and resources. Simultaneously, agroecology, in the more political understanding of the term, can serve as an evaluative framework for agri-food transition processes to augment our understanding of intermediaries in sustainability transitions. This mini-review presents an overview of the emerging sustainability transition intermediary literature, an introduction to CLC agriculture's transition intermediaries, and the research gaps highlighted from an agroecological perspective. Integrating an agroecological lens attentive to the science, practice, and politics of intermediating agricultural transitions, this review proposes an adapted framework to understand and assess CLC agriculture's intermediaries. Thus, CLC agriculture presents a unique opportunity to iteratively draw upon and advance the sustainability transition intermediary literature.


A novel (Ba,Bi,Nb)-doped TiO2 ceramic was previously proved to be potentially useful as a varistor material. The present work attempts to clarify the roles of the dopants, Ba and Bi. Varied atmosphere compensation is an effective method to achieve the goal. The results show that varied atmosphere compensation had only a little influence on grain growth and microstructures in the interior of the sintered samples, whereas the varistor properties were affected greatly. Samples compensating with Ba are more beneficial to the boundary barrier than samples compensating with Bi only. Furthermore, samples compensating with both Ba and Bi are better than those compensating with Ba only. This is induced by different degrees of Bi evaporation and Ba diffusion from sintered compacts when sintering proceeds at high temperature.


Public possession of fully symmetrical information is only a relative and ideal state, and asymmetry of information is widespread. This is truer with a public that has experienced the sufferings of SARS. The public ability of discrimination and the mutual response between government and the public seem extremely important. Moreover, only with more rationality can both government and the public avoid reverse choices and ethic risks under asymmetrical information situations.


The performative power of mainstream economic theories (notably agency theory and transaction cost economics) has been criticised by researchers within management studies. The latter blame these theories for creating 'bad' management in real-world organisations and call for their removal from business schools. This paper questions this line of criticism. It argues that mainstream economic theories have condoned more than created 'bad' management. It also questions whether 'bad' management can be negated by ousting these theories from business schools. Rather it is argued that 'bad' management has deep roots within organisations—specifically, it reflects on how organisations are run by and in the interests of capital owners. The possibilities for securing comparatively enlightened or 'good' forms of management are seen as necessarily limited by capitalist ownership relations. The paper argues that the transformation of management will require wider reforms in—and importantly beyond—business schools.


awte, a multiple-stages and multiple-antigens hybrid epitopes gene of Plasmolium falciparum, was amplified by PCR, sequenced by automated by DNA sequencer and cloned into pBV220, pEX31b, pKEN and pGEMEX1 vector. The recombinant thermal inducible plasmids pBV220-AWTE and pEX31b-AWTE were introduced into E.coli strains. After a heat shock from 30℃ to 42℃, the fusion protein MS2-AWTE was expressed by pEX31b-AWTE engineering bacteria while non-fusion protein AWTE was not expressed by DH5α(pBV220-AWTE). The recombinant IPTG inducible plasmids pKEN-AWTE and pGEMEX1-AWTE were introduced into E.coli strains. After IPTG induction, There was no obivious expression in non-fusion form AWTE by DH5α(pKEN-AWTE), but the gene does expressed pGEMEX1-AWTE engineering bacteria when fused to T7Φ10 at C terminal. Fusion proteins of MS2-AWTE and T7Φ10-AWTE were partially purified and show to be immunogenic by indirect enzyme linked immune adsorbent assay (ELISA).


We show that dark matter abundance and the inflationary scale H could be intimately related. Standard Model extensions with Higgs mediated couplings to new physics typically contain extra scalars displaced from vacuum during inflation. If their coupling to Standard Model is weak, they will not thermalize and may easily constitute too much dark matter reminiscent to the moduli problem. As an example we consider Standard Model extended by a Z2 symmetric singlet s coupled to the Standard Model Higgs Φ via λ Φ†Φ s2. Dark matter relic density is generated non-thermally for λ ≲ 10−7. We show that the dark matter yield crucially depends on the inflationary scale. For H∼ 1010 GeV we find that the singlet self-coupling and mass should lie in the regime λs≳ 10−9 and ms≲ 50 GeV to avoid dark matter overproduction.


Abstract Surgical personnel in contact with patients or clinical material are at continuous risk of acquiring blood-borne infections (BBIs), in particular hepatitis B virus (HBV), hepatitis C virus (HCV), and the human immunodeficiency virus (HIV). Recent concerns have highlighted the potential risk of prion transmission during surgery. It is impossible to prevent all exposures to potentially infected materials. Strategies to combat occupational infection include the universal use of precautions to avoid exposure, immunization, and post-exposure management. Relevant procedures also should include steps to minimize any threat to patients.


The study was carried out in the Poultry Science Lab, the Faculty of Breeding, Halu Oleo University, Kendari for 6 weeks in April to may 2019. study aimed to found out the production of quail (Cortunix-cortunix japonica) layer phase that fed sprout meals green beans (Phaseolus radiatus L) in different levels. The material study used was 64 a six mont old quail phase layer wich fed sprouts meals green beans (Phaseolus radiatus L.) in the feed. This study used Completely Randomized Design consisting 4 streatments and 4 replication. The treatment were: basal feed without the addition of sprouts meals (P0), basal feed + 3% meals sprouts (P1), basal feed + 6% sprouts meals (P2) and basal feed + 9% sprouts meals (P3). The parameters measured were: feed consumption, egg production, eggs weight and feed conversion. The results of the study showed that the quail fed sprouts meals till 9% in feed was no significantly affect (P>0,05) on feed consumption, eggs weight and feed conversion. Whereas sprouts meals was significantly affect (P<0,01) on egg production. In conclusion, the quil which feed sprouts meals is not affect the performance but significantly affect the egg production.


Effects of partial pressure of oxygen and temperature on oxygen reduction kinetics on a submerged gold electrode in lithium carbonate melt were investigated using cyclic voltammetry and impedance analysis. Cyclic voltammetry measurements indicated that the oxygen reduction reaction in Li{sub 2}CO{sub 3} melt is reversible up to 200 mV/s. The impedance analysis was carried out using a Complex Nonlinear Least Square (CNLS) paxameter estimation program based on the Randles-Ershler equivalent circlet. This analysis technique was used to estimate the electrode kinetics and the mass transfer related parameters such as the charge transfer resistance (R{sub ct}) and the Warburg coefficient {sigma}. The mass transfer related parameters obtained from cyclic voltammetry and impedance analysis were in good agreement. The reaction orders for oxygen at 800{degrees}C were calculated to be 0.38 for the exchange current density and 0.5 for the product D{sub o}{sup {1/2}}C{sub o}*; these values are consistent with the mechanism proposed in the literature for oxygen reduction in Li{sub 2}CO{sub 3} melt on a submerged gold electrode.


We consider extensions of the standard model inspired by intersecting D-brane constructions, in order to address flavor mass textures. We include additional anomalous gauge symmetries, and scalar fields to break them and to generate Froggatt-Nielsen mass terms. Green-Schwarz axions are included to cancel mixed anomalies rendering the models consistent. At low energies, a residual anomalous global symmetry remains, and its associated pseudo-Goldstone mode becomes the physical axion, which can be interpreted as an axion arising from open string modes. General considerations show that such axions are very common in D-brane models and can be completely incompatible with current bounds. Astrophysical constraints are placed on the axion both by including neutrino masses in the Froggatt-Nielsen scheme and considering QCD instanton contributions to the axion mass. We find simple models where the axion decay constant is in the allowed range, but only one such minimal model with this property is free from excessive fine tunings elsewhere. We also note that generically addressing flavor textures for the CKM matrix leads to deconstructed extra dimensions.

With a keen critical eye and sharp insight Sylvia Lawson moves the essays and stories in this collection through settings in and out of Australia across Paris, West Papua, Britain, Indonesia listening to the distinctive local voices from our cultural margins and reclaiming concerns the metropolitan centres ignore.


A ECT_ECU (1020) executes a program, comprising the steps of: i) determining a target idle speed (step S100), ii) terminating a neutral control (step S110) when, during control of the neutral state (YES at step S102), the target idle speed is equal to or greater than a predetermined threshold nidle (YES at step S104), and iii) execution of the neutral control (step S106), if, while the neutral control is not executed (NO at step S102), the target idle speed is less than the predetermined threshold NIDLS (YES at step S108).


By eliminating the data offset caused by a disturbing magnetic field during the flying condition of a spinning projectile, an adaptive unscented Kalman filter is applied to estimate the actual data of a geomagnetic field and the false value introduced by a disturbing magnetic field. For the ratio methods related to geomagnetic attitude measurement, the physical significance of the ratios obtained by all ratio methods is clarified. A new definition for the ratio is presented to ensure online estimation and numerical stability. The variation in the sensor outputs along the lateral directions is suggested to be a harmonic motion with the assumption that the spindle is fixed or in slow motion. The true data employed as a reference for comparison is generated by a dynamics model for spinning objects and by projecting the geomagnetic field to the measurement frame. Signal gathering and data preprocessing are considered. A signal-disturbing ratio is introduced to indicate the proportions of the real geomagnetic signal and the interference signal in the data acquisition process. The algorithm of the adaptive unscented Kalman filter is discussed. Simulations are performed using a 1 kHz sample rate and a duration of 60 seconds. The filtering results supported by a conventional unscented Kalman filter and adaptive unscented Kalman filters are compared with actual data for the conditions of different signal-disturbing ratios and 10 shifts of the disturbing magnetic field. The results of the simulation indicate that the proposed adaptive unscented Kalman filter with the introduced state equation achieves better performance than other filters mentioned in the paper. The filter has the ability to provide clean data from the noisy data flow measured from a spinning projectile for the ratio methods based on the geomagnetic measurements.


PT Saptaindra Sejati (SIS) is a company engaged in coal services, the company produces pallet boxes which is a fabrication product that is currently the demand is always there and desirable customers. The pallet uses the main raw materials such as iron elbows, iron pipes and iron plates. The production of pallet-making boxes is strongly influenced by the increase in material prices and the costs required for the process. One method of product improvement is approximated by design for manufacturing (DFM). This method is a design method that will be used for manufacturing minimum product requirement of components, printing and quality. PT Saptaindra Sejati in the fabrication section that makes pallet boxes focus on reducing components and improving production quality. Reduce components done by non-tobacco materials but still improve product quality. The production process can be improved by simplifying the production process. The main purpose of the process is the cost that can minimize production and quality. The result of DFM implementation to produce 1 pallet box will produce production cost up to 20,0% and quality cost up to 27,1%.

This article reviews the two primary frameworks used to explore the external relations of regions. It argues that the concepts of multi-level governance and paradiplomacy are used to describe similar, but distinct, international activities on the part of regions and sub-state governments. Both approaches look at the ways in which regions engage beyond the local level, and increasingly so. The inevitable overlap between their subject matter has meant that the two terms are sometimes used interchangeably, leading to a mischaracterisation of the practices themselves. The international mobilisation of regions manifests in numerous modes, and therefore much greater specificity is required in analysing and interpreting these varied phenomena. In particular, the novelty of paradiplomacy, and the political contestation that it can imply, risks being under-reported. Firmer boundaries between the two approaches, and a better conceptualisation of the relationship between them, are called for in this interdisciplinary review. The article argues that where multi-level governance presents a predominately structural account of 'governance' based activities, paradiplomacy has the potential to provide an agency-oriented explanation of autonomous, diplomatic practices – often with deeply political connotations. It is suggested that the two can represent parallel, alternative or complementary approaches, depending on the exact nature of the activity under consideration. It concludes by suggesting future avenues for paradiplomatic research.


A variable‐path ultrasonic interferometer has been modified to permit automatic data collection and analysis utilizing an Apple IIe microcomputer and an ADC interface board possessing a crystal‐controlled clock for precision data sampling. The micrometer screw is driven by a synchronous motor also controlled by the interface board. The system allows rapid sampling and recording of the crystal driving voltage for each resonant node in the gas column, thereby reducing running time and improving overall accuracy and sensitivity. For SiF4, the (single) vibrational relaxation time was found to be (2.20±0.14)×10−8 s at a temperature of 304 K and 1 atm of pressure.


An Al-Si/Al+Al2O3 coating was prepared on the AZ91D Mg alloy substrate by a new processing technique of laser plasma and with the combination of spraying,and the influences of the laser power to the structure and properties of the coating were studied.X-ray diffraction(XRD) and scanning electron microscope(SEM) were used to identify the phases and to study the morphology respectively.By the porosity ratio of the coating material was measured by using an optical microscope(OM) and the microhardness was measured using a micro Vickers hardness tester.The results show that the Al-Si transition layer improves the adhesion of the coating obviously.When the laser power is 1800W,the unmelted particles are less and the coating is the densest.The coating is composed of Al phase and α-Al2O3 phase and no surviving γ-Al2O3 phase existed.The porosity ratio decreases from 4.5% to 2.6% with the increase of the laser power.But when the power is more than 1800W,the porosity ratio increases.The hardness increases from HV0.0555 to HV0.05275 after spraying.The hardness of the surface is the largest and increases with the increase of the laser power.But when the power increases to 2000W,the hardness has no big change.


Two novel bi-dodecyl bi-phosphate compounds, DGDP and PDP were synthesized from phosphorous oxychloride, diethylene glycol (hydroquinone) and dodecanol via the esterification of two steps and the hydrolization of one step, and were purified by recrystallization in absolute ethyl alcohol. Their structures were characterized by IR, 1H NMR, MS and potentiometric titration. The results of potentiometric titration show that the acid strength of the two hydroxyls in bi-dodecyl bi-phosphate(DGDP,PDP) was nearly identitcal. Their ionization constants at 25 ℃ are 3.940×10-4 mol/L(DGDP) and 4.255×10-3 mol/L(PDP) respectively. The critical micelle concentrations of their aqueous solutions at 20 ℃ are 9.0×10-4 mol/L(DGDP) and 1.3×10-3 mol/L(PDP) respectively. Their coefficients of surface tension at 20 ℃ are 34.49 mN/m(DGDP) and 36.14 mN/m(PDP)at CMC respectively.


We present a cloud based solution for automated processing of 3D full body scans into 3D printable figurines. Digital representations of the outer surface of human beings have many different applications. One popular application is the physical production of 3D printed figurines. However, a raw 3D scan is not necessarily 3D printable, and if it is, it might be too fragile to be practically useful. Furthermore, straightforward printing of a scan on a state-of-the-art 3D color printer is not desirable due to the considerable color differences between the digital model and the physical reproduction. Therefore, preprint processing is recommended. Manually performing these tasks requires specialized knowledge, software and a substantial amount of time. We automate these tasks and offer them as a cloud service in order to reduce processing time as well as financial costs. In order to produce a decent 3D color print starting from a 3D scan, several types of processing are needed. We distinguish between (a) color corrections, (b) thickening thin components, (c) clutter and floor removal, (d) creating a watertight mesh, (e) adding a sufficiently stable baseplate, (f) rotate the scan so that the face looks into the right direction, (g) smoothing the full scan except for the face (h) optionally hollowing the scan and drilling escape holes and (i) some other trivial tasks such as scaling and rotating the scan. For each of the challenges mentioned, we present a fully automated solution to the problem. Currently we cannot solve issues such as non-trivial missing parts in the scan and incorrect color reprojections in the texture. In the future we will investigate on how to solve some of the issues by taking a machine learning approach on a large database of manually corrected scans.


In the context of the Bologna process, e-learning experiences are being promoted in many European universities. Recently, the Universidad Politécnica of Valencia (UPV) has implemented the Poliformat platform that is based on the Sakai environment. Last year, a pilot experience was developed to test this environment for undergraduate courses in a Computer Engineering degree. The current work describes an elearning application of the Poliformat platform in an Operating Systems online course. The experience has been evaluated using survey techniques that analyse online learning issues and also technical aspects related to the Poliformat platform. Globally, the experience was rather positive although some problems were detected in the evaluation process that revealed that e-learning methods and tools have to be improved.


Optical code division multiple access (OCDMA) offers several attractive features like asynchronous access, privacy and security in transmission, ability to support variable bit rate and bursty traffic, and scalability of the network. An optical orthogonal code (OOC) is a collection of binary sequences with good correlation properties which are important factors of determining the capacity of OCDMA systems. In this paper, a combinatorial construction of simple 2- dimensional (2-D) OOCs with autocorrelation 0 and crosscorrelation 1 is proposed. These codes are called single or no pulse per row (SNPR) codes and they can simplify the correlator structure without over- compromising the cardinality of the codes. Also, they can give the scalability to the OCDMA network consisting of various smaller networks. The upper bound on the size of SNPR codes is derived for various cases and the BER performance and blocking probability of these codes are evaluated.


In order to determine the relatoinship between the Al content and the peak wavelength of quantum well infrared photodetector(QWIP).and establish another one between characterization of microstructure and macroscopic properties of samples.The author designed two device-samples with different Al content based on the bound to the quasi bound state transitions(b-qbQWIP) modle.Corresponding tests have been done,including photoresponse spectra,photoluminescence spectra and high resolution transmission electron microscopy(HRTEM).The relation between Al content and the peak wavelength is analyzed and discussed in theory.Two sample-devices of GaAs/AlxGa1-xAs quantum well infrared photodetectors have been made by using metal organic chemical vapor deposition(MOCVD).Al content of 1# sample is 0.23 while that of 2# one is 0.32.The photoresponse spectra are obtained at 77 K by using Fourier transform spectrometer while photoluminescence spectra are tested at room temperature for two sample-devices of GaAs/AlxGa1-xAs quantum well infrared photodetectors.The peak wavelengths of 1# and 2# are 8.36 μm and 7.58 μm from photoresponse spectra,while the ones are 9.672 μm and 7.928 μm according to Schrodinger equation.The main reason for 1# error much larger is crystal lattice mismatch between GaAs and AlGaAs and not precise controlling during growth of quantum well material after the crystal structure is investigated by using high-resolution transmission electron microscope(HRTEM).It shows that reducing Al content will lead to subband narrowed and peak wavelength red-shift.Photoluminescence results are consistent with Schrodinger equation.


Abstract In this paper, we characterize the equilibrium measure for a family of nonlocal and anisotropic energies I α I_{\alpha} that describe the interaction of particles confined in an elliptic subset of the plane. The case α = 0 \alpha=0 corresponds to purely Coulomb interactions, while the case α = 1 \alpha=1 describes interactions of positive edge dislocations in the plane. The anisotropy into the energy is tuned by the parameter 𝛼 and favors the alignment of particles. We show that the equilibrium measure is completely unaffected by the anisotropy and always coincides with the optimal distribution in the case α = 0 \alpha=0 of purely Coulomb interactions, which is given by an explicit measure supported on the boundary of the elliptic confining domain. Our result does not seem to agree with the mechanical conjecture that positive edge dislocations at equilibrium tend to arrange themselves along "wall-like" structures. Moreover, this is one of the very few examples of explicit characterization of the equilibrium measure for nonlocal interaction energies outside the radially symmetric case.


Brassinosteroids (BRs) are a class of phytohormones that modulate several important agronomic traits in rice (Oryza sativa). GSK2 is one of the critical suppressors of BR signaling and targets transcription factors such as OsBZR1 and DLT to regulate BR responses. Here, we identified OFP3 (OVATE FAMILY PROTEIN 3) as an interactor of both GSK2 and DLT by yeast two-hybrid screening and demonstrated that OFP3 plays a distinctly negative role in BR responses. While knockout of OFP3 promoted rice seedling growth, overexpression of OFP3 led to strong BR insensitivity, which resulted in reduced plant height, leaf angle, and grain size. Interestingly, both BR biosynthetic and signaling genes had decreased expression in the overexpression plants. OFP3 overexpression also enhanced the phenotypes of BR-deficient mutants, but largely suppressed those of BR-enhanced plants. Moreover, treatment with either BR or bikinin, a GSK3-like kinase inhibitor, induced OFP3 depletion, whereas GSK2 or brassinazole, a BR synthesis inhibitor, promoted OFP3 accumulation. Furthermore, OFP3 exhibited transcription repressor activity and was able to interact with itself as well as additional BR-related components, including OFP1, OSH1, OSH15, OsBZR1, and GF14c. Importantly, GSK2 can phosphorylate OFP3 and enhance these interactions. We propose that OFP3, as a suppressor of both BR synthesis and signaling but stabilized by GSK2, incorporates into a transcription factor complex to facilitate BR signaling control, which is critical for the proper development of various tissues.


The invention discloses an on-line monitoring system of fatigue damage to an electric transmission line conductor by breeze vibration. The on-line monitoring system comprises a conductor vibration line monitoring device and a meteorological environment observation station, wherein the conductor vibration line monitoring device and the meteorological environment observation station are connected with the line, data collected by the conductor vibration line monitoring device and meteorological environment data monitored by the meteorological environment observation station in real time are sent to a site line monitoring communication base station through a wireless sensor network, subjected to digital processing by the site line monitoring communication base station and transmitted to a database server of a local monitoring center through a data remote transmission system, and after a data processing and analyzing system of the database server of the monitoring center analyzes on-line monitoring information, on-line data are provided for clients through the on-line monitoring information of the Internet.

Establishing the time of minimum between cycles 22 and 23 is complicated because there are two periods of low solar activity during 1996. To resolve this controversy, we studied the time of minimum in terms of the historical basis for defining this fiducial point in the solar cycle using several measures of solar activity, as well as the cycle membership of active regions observed during the minimum phase between these two cycles. Our conclusion is that cycle minimum is not defined solely on the basis of the occurrence of the minimum in the smoothed sunspot number, but rather by several additional parameters, including the monthly (or rotationally) averaged sunspot number, the number of regions (total, new- and old-cycle), and the number of spotless days. Using these specific measures of solar activity, we recommend that the minimum between cycles 22 and 23 occurred in September 1996 (1996.7) and not in May 1996 (1996.4).


Local organization building is part of many development interventions, especially in those programs directed at disempowered groups, such as women. Since the mid-1980s, it has been argued that the formation of women's organizations should follow local, indigenous organizing practices. It should moreover be built on existing, informal organizational institutions, such as social networks and neighbourhood groups. The study presented here looks into a case where official organizations aim to organize agrarian women who had already formed their own rather informal groups. The conflictual dynamics that unfold suggest several issues of knowledge, power and control in relating to local organizations.

Abstract:Since the economic reform launched in 1978, China has witnessed a vast group of rural women leaving their families behind in the countryside to enter urban middle-class homes as domestic workers. However, these domestic workers' physical and emotional closeness to their employers is often seen as a problem, sometimes even a threat to the maintenance of the proper domestic order. Recently, a growing number of domestic workers have participated in the Literature Group at the Workers' Home in Picun to break the longtime silence to tell their own stories revealing social injustices and inequalities at the intersection of gender and class.

The proper time for forensic cell to catch evidence is given out. And the digital watermark method of encapsulation and preservation for digital evidences is introduced. The experiments show that the model has the features of self-adaption, self-learning, distribution, and real time.


The estimation of a narrowband time-varying channel under finite block length and transmission bandwidth is investigated. A novel method is proposed for estimation in the delay-Doppler domain by exploiting structural constraints on low-rank matrix recovery. The proposed algorithm uses Gauss-Seidel iterations on the low-rank parameterization under noisy training signal measurements. Theoretical global identifiability results for the channel leakage (due to finite block length and transmission bandwidth) are stated and the necessity of considering Doppler shift induced structure is demonstrated. Justification is provided for the choice of simulation parameters and initialization strategies to achieve good convergence rates and some ill-posed scenarios are also described. It is further shown that simple sparsity-based algorithms like basis pursuit/nuclear norm minimization do not perform well on the said constraint set for measurement operators arising out of training sequences.


should engage in each type of deception, Scheussler turns to three case studies "marked by different levels of domestic opposition to war" (p. 25). World War II serves as an instance when the public was in no mood for war and had to be led step by step into the fray by Franklin D. Roosevelt, who had been keen to help the Allies for years prior. During Vietnam, Lyndon B. Johnson did not face strenuous opposition initially, though support for the war was middling at best. Finally, in the case of the 2003 Iraq War and George W. Bush, the public was far more "permissive" and open to the idea of conflict. These cases illustrate Scheussler's theory nicely. FDR engaged in significant blame shifting and turned a war-weary public into one clamoring for revenge after Pearl Harbor. LBJ, by contrast, employed "a creeping form of blame-shifting" (p. 26), which later led to his undoing after his attempts at deception became known. Finally, George W. Bush exhibited classic overselling behavior. In the wake of the September 11 attacks, the public was more open to the idea of war, and elected officials were afraid of looking "soft on terror." This created an opening for Bush to pivot from Afghanistan to Iraq, emphasizing the threat posed by Saddam Hussein and his alleged stockpiles of weapons of mass destruction. This move, of course, would later come back to haunt Bush as it became more clear that the threat was overblown. These cases are useful in several regards. First, they illustrate a clear link between domestic political circumstances and the type of deception a leader will employ. They also illustrate the tremendous potential for blowback, which Schuessler discusses explicitly, especially in the context of Vietnam and Iraq. They also shed light on an underexplored topic in the literature: the crucial finessing that leaders must engage in, both for the public and for elites behind closed doors, in the period immediately preceding a war. The majority of the public opinion literature focuses on how leaders work to maintain approval in wars that are ongoing. Scheussler focuses on the thought that goes into the ways to pitch a war to the public and the choices leaders have to make concerning what information to reveal or keep under wraps. Deceit on the Road to War makes several important contributions. Like any good book, however, it also raises some interesting questions. First, is there ever an incentive for democratic leaders not to use deception? From Scheussler's account, engaging in either overselling or blame-shifting behavior can increase the public's tolerance for conflict, hence extending the leader's ability to conduct the war as he or she sees fit. According to the theory, blame shifting would happen in wars that are expected to be hard, while overselling would be associated with wars whose victory is assured. Are leaders less likely to deceive if the war is to be somewhere in between these two points? Scheussler notes the possibility of blowback, but does not make clear whether the fear of this retribution is what keeps leaders honest (if, indeed, they ever are). Part of the appeal of his argument is that it is very easy to come up with examples of other American presidents not featured in his case studies who have engaged in similar behavior. Some variation in this regard (if such an example exists) would have served as an informative counter to the other cases. Second, the book does not fully address the question of the amount of power a president has in shaping the narrative surrounding a war and in leading public opinion. This shortcoming is by no means unique to this book, but it was noteworthy here given the centrality of the bully pulpit to Scheussler's argument. He notes that many scholars "assume that leaders' ability to manipulate public opinion is highly constrained" (p. 20), but does not elaborate on the limits of these constraints when it comes to overselling or blame shifting. Are presidents always at a disadvantage in shaping the narrative, or, as other scholars have argued, can they create public consent by virtue of being the chief foreign policy actor? The author pays a great deal of attention to the former, but the ability for presidents to do the latter (at least to some degree) is implicit in his argument. Which characterization is more accurate? In the context of World War II, for instance, was a major event like Pearl Harbor necessary to push U.S. public opinion past a certain threshold? Or could FDR have made a case earlier by laying out the dangers of leaving Germany unchecked more forcefully? Scheussler mentions FDR's ominous fireside chat that warned of Americans "living at the point of a gun" (p. 29), but then goes on in the following pages to describe the president's reluctance to do more in the public eye. This implied that FDR knew that the time was not right, but left me wondering a) what threshold he was waiting to cross and b) why he did not take a more proactive role in trying to get the United States to war faster. In sum, there is a great deal to like about Deceit on the Road to War. It speaks to a key issue that should be of interest to scholars of both international relations and American politics. It also sheds a considerable amount of light on the complex relationship between leader and citizen during times of war. Finally, it also raises interesting questions about the limits of presidential power and the nature of democratic accountability.


ABSTRACT In this study, I examine the impact of oil price volatility on corporate decisions, namely corporate investments and dividend policy. Using a sample of 356 firms from The Gulf Cooperation Council markets spanning from 2005 to 2015, I show that corporate investments and the likelihood of paying dividends is largely influenced by oil price volatility. The evidence suggests that firms tend to invest less and are more likely to choose not to pay dividends during periods of high oil price volatility. Furthermore, I find that the impact of oil price volatility on corporate decisions tends to be stronger in financially constrained firms, using firm size as a proxy. The findings of this study are robust to controlling for macroeconomic volatility and using alternative measures of oil price volatility and alternative econometric approaches.


SYNOPSIS Objective. Emotional availability (EA) is a relationship construct that can be considered a global index of the emotional quality of parent–child interaction. The present study aimed to address several specific questions about mother–child and father–child emotional availability in families with a child with Down's syndrome (DS). Design . Free-play interactions of 22 children with DS (M chronological age = 35.32 mo) We coded separately with each parent using the Emotional Availability (EA) Scales (Biringen, Robinson, & Emde, 1998). Results . Overall, mothers and fathers and their children with DS were equally emotionally available to one another. Bivariate correlations between maternal and paternal EA ratings of Sensitivity, Structuring, and Nonhostility showed significant positive associations. Moreover, bivariate correlations also highlighted the stability of child Responsiveness and Involvement across interactions with the two parents. There were no differences between mothers and fathers in mean levels of Sensitivity, Structuring, Nonintrusiveness, or Nonhostility, nor were there differences in mean levels of child Responsiveness and Involvement between mother–child and father–child interactions. Conclusions . We discuss the clinical utility of the EA Scales for assessing relationships between parents and their children with DS.


The main objective of this investigation was to study the effects of genotype, levels of 2,4-D (2,4-dichloro-phynoxyacetic acid) concentrations and their interaction on immature embryo induction in wheat. In addition, to partition the phenotypic variances presented in this process to its components and subsequently, estimating the heritability percentages for in vitro traits. The genetic materials used in this study were six varieties. Three varieties belong to the species (Triticum aestivum L.) and another three varieties belong to the species (Triticum durum L.). These genotypes were in vitro evaluated for immature embryos culture ability at three levels of 2,4-D. The results showed the presence of significant differences among genotypes at the three levels of 2,4-D for all in vitro traits except for responding embryos and number of regenerated plants at B level as well as number of tillers per plant at A and B levels. Furthermore, levels and genotype x levels interaction of mean squares were highly significant with respect to all the studied in vitro traits except in a few cases. This indicates that these genotypes gave different response at different 2,4-D levels. The results revealed that greatest percentages values for responding embryo, green points, number of plantlets, plant height and root length were recorded for Benysweif 5. In addition, Sohag 3 was the best variety for responding embryos, callus weight and number of calli. Whereas, the greatest values for plant weight and number of tiller were observed in Benysweif 4. Therefore, durum varieties are more suitable for immature embryo culture compared to aestivum varieties. Furthermore, the results revealed that the genetic variation were high and positive for most of studied traits. This finding is emphasized by the heritability values, which were more than 60% for all studied traits except for responding embryos, plant weight and number of tillers/plant. In addition, the values of genetic levels of interaction variations were high and positive in all studied in vitro traits. This finding explains the low values of heritability in these traits as well as the genes control these traits are highly affected by media compositions.


Objective To investigate the significance of serum IL-18 in the prognosis of colorectal carcinoma.Methods The serum IL-18 was detected by enzyme-linked immunosorbent assay(ELISA) in 106 cases of colorectal carcimoma and 60 healthy control.Results The mean serum IL-18 level was 338.46 pg/ml in patients before June 1997 and 328.85 pg/ml in patients after June 1997,showing no significant difference between them(P0.05).The mean serum IL-18 level was significantly higher in patients with colorectal carcinoma than in the healthy control(P0.05).The serum IL-18 was much higher in patients with StageⅡ,stage Ⅲ and stage Ⅳ disease than in the healthy control(P0.05).The 5-year survival rate was 5.3% for patient with serum IL-18 ≥346 pg/ml(n=47),and 18.6% for patients with serum IL-18 346pg/ml(n=57),showing a significant difference between them.Multivariate analysis using a Cox proportional hazards model identified the serum IL-18 as an independent prognostic factor for patients survival in colorectal carcinoma.Conclusion The serum IL-18 level has a close correlation with the survival curve and may be an important postoperative prognostic indicator in colorectal carcinoma.


Aims of research. The task is to apply modern strength criteria of anisotropic materials for the calculation of multilayer walls made of cellular concrete and silicate large masonry materials, which differ in exact dimensions and allow for thin-seam masonry with adhesive seams. Proposals for the inclusion in the design standards of guidance that takes into account the work of wall materials in complex stress states will be presented in a series of publications. Methods. The strength criteria of G.A. Geniev in a rather simplified form are used. The volumetric stress state of walls made of orthotropic materials is considered. The basis for the construction of strength criteria are three possible different mechanisms of destruction - separation, compression and shear. For modern thin-walled masonry is characterized by a combination of compressive (vertical) and shear (horizontal) loads. Of particular interest is the work of the masonry shift, since the plane stress state is not sufficiently studied. The article is devoted to the construction of the criterion of masonry shear strength. The peculiarity of the proposed calculations is the comparative simplicity of the strength criteria due to the accepted hypotheses. Results. The final expression of the shear strength criterion and the sequence of the shear strength verification in the case of simple loading are presented. The article is preliminary for a series of calculations and results of experimental studies of the walls under different operating conditions and different loads.


An alloantiserum has been obtained in the mouse which differentiates specifically between lymph node cells and a sub‐population of peritoneal cells. The antigen is associated with chromosome 7 (linkage group I).


In the present work a new algorithm, Feed-Back Stacking (FBS), to discriminate better between primary and other interfering events, is presented. The method has been developed especially in order to improve stacking velocity determination of difficult data. For velocity analysis a new version of Constant Velocity Stack (CVS) which incorporates the FBS method is proposed. with the new type of analysis a stepwise relative reduction or change of noise events will occur. The changes itselves are used as a criterium to discriminate between the different events. The new algorithm (FBS) shares the principle of a stepwise change of events with the Superstack method (Naess, 1979), but is otherwise different. Especially, the FBS is a linear method while Superstack is not.


Lots of researches have shown that the optimization of building envelope reduces building energy consumption during its lifecycle. Due to the uncertainty of the relationship between individual design parameters and building performance, the extent of impact cannot be well-understood. Therefore, it is essential to evaluate the impact extent for different design parameters and identify the one (s) that impact (s) more to the building performance and hence focus so as to improve building performance efficiently. In the present research, main design parameters that affect the building performance are selected to analyse the extent of the impact. Material quantities are extracted directly from the Building Information Modelling (BIM) model so as to calculate the embodied energy in material. Moreover, simulation of energy consumption is run for different scenarios during operation stage. Energy embodied in typical construction materials are calculated for each scenario accordingly. Finally, sensitivity analysis is applied to find the extent of impact on life cycle energy of building for the selected design parameters in terms of both embodied energy (EE) and operational energy (OE). A case study of a manufactory plant is carried out to investigate the impact of the selected design parameters.

Objective This study was to discuss a new model of health education of osteoporosis.By setting up osteoporosis club as a health education platform,we studied the significance of this model in popularizing osteoporosis health knowledge in China. Methods We set up a club of osteoporosis,and adopted the unified management of the membership.A total of 1208 subjects,in which diagnosis of osteoporosis was established from January to May 2010,were enrolled,including 435 males,with an average age of(60.72±5.85) years,and 773 females,with an average age of(61.06±6.27) years.During the observation duration of 1 year, multiple activities of health education were carried out,including health education lecture once a month,outdoor sports such as climbing mountains and sunshine exposure.Comprehensive management considering dietary,sports and medication was also performed.All subjects filled in questionnaire to build a database,including osteoporosis cognitive level,pain degree evaluation, appraisal of life quality and bone mineral density(BMD) testing.All data were statistically analyzed by SPSS 11.5 software.Results After one year observation,cognitive level of osteoporosis was significantly raised[(10.07±0.27) vs(3.81±0.24) points);VAS pain visual analogue scale significantly reduced[(1.56±0.24) vs(5.71±0.83) points];appraisal of life quality significantly improved [(80.64±10.98) vs(66.38±7.72) points];and the BMD of L_(2~4),Neck,Ward's,Troch significantly increased in both males and females respectively[males:(1.18±0.11) vs(1.02±0.22)g/cm~2,(1.03±0.10) v.v(0.89±0.15)g/cm~2,(0.89±0.12) vs(0.76±0.09)g/cm~2,(0.78±0.17) vs(0.62±0.12)g/cm~2;females:(1.20±0.17) vs(1.01±0.18)g/cm~2,(1.01±0.13) vs(0.88±0.05)g/cm~2, (0.87±0.09) vs(0.74±0.1 l)g/cm~2,(0.76±0.21) vs(0.60±0.07)g/cm~2].The differences reached the statistical significance(P0.05). Conclusion With population aging,the prevalence rate of osteoporosis increases.However,people have little awareness about this disease.It is significant to emphasize osteoporosis health education.Osteoporosis club,as a new model of health education,plays an important role in the comprehensive management of osteoporosis.


Background: COVID-19 vaccine trials and post-implementation data suggest vaccination decreases SARS-CoV-2 infections. Objective: Estimate COVID-19 vaccinations impact on SARS-CoV-2 case rates and viral diversity among healthcare workers (HCW) during a high community prevalence period. Design, Setting, Participants: A prospective cohort study from Boston Medical Center (BMC)s HCW vaccination program, where staff received two doses of BNT162b2 or mRNA-1273. Measurements: PCR-confirmed SARS-CoV-2 cases among HCWs from December 09, 2020 to February 23, 2021. Weekly SARS-CoV-2 rates per 100,000 person-day overall and by time from first injection (1-14 and >14 days) were compared with surrounding community rates. Viral genome sequences from SARS CoV-2 positive samples. Results: SARS-CoV-2 cases occurred in 1.4% (96/7109) of HCWs given at least a first dose and 0.3% (17/5913) of HCWs given both vaccine doses. Adjusted SARS-CoV-2 infection rate ratios were 0.73 (95% CI 0.53-1.00) 1-14 days and 0.18 (0.10-0.32) >14 days from first dose. HCW SARS-CoV-2 cases >14 days from initial dose compared to within 14 days were more often older (46 versus 38 years, p=0.007), Latinx (10% versus 8%, p=0.03), and asymptomatic (48% versus 11%, p=0.0002). SARS-CoV-2 rates among HCWs fell below those of the surrounding community, with a 18% versus 11% weekly decrease respectively (p=0.14). Comparison of 48 SARS-CoV-2 genomes sequenced from post-first dose cases did not indicate selection pressure towards known spike-antibody escape mutations. Limitations: Unable to adjust for infection risk outside of the workplace. Lack follow up on symptoms post SARS-CoV-2 diagnosis. Small number of vaccinated HCW cases. Conclusion: Our results indicate a positive impact of COVID-19 vaccines on SARS-CoV-2 case rates. Post-vaccination isolates did not show unusual genetic diversity or selection for mutations of concern.


Nanoindentation of biological cells and thin biomembranes has been demonstrated to be an effective means for measuring and understanding the mechanical behavoir of these bio-entities with relatively small dimensions and unusual mechanical properties. Several new and variant indentation techniques have been developed recently. New solid mechanics modules spanning multi-scale indentation deformation are constructed to analyse the force-displacement data so that the quantitative materials parameters can be found.


In order to have a meaningful debate about the treatment of primary hyperparathyroidism (PHPT), it is essential to define what is meant by "cure." Unfortunately, the definition that Dr Terris used when he reported his results for 112 patients whom he treated over a 4-year period—normocalcemia at 6 months—is pervasive in the literature. As Drs Terris and Stack point out, our 3 patients who had calcium levels >10 may prove over time to be surgical failures, but according to the standard that they have used to judge their own results, these "normocalcemic" patients would have been regarded as "cured." We advocate a more rigorous standard that is based on simultaneous calcium and parathyroid hormone (PTH) measurements so that patients with normocalcemic PHPT will not be mistakenly labeled as "cured." In addition to dispensing with normocalcemia as the benchmark for defining who has been "cured," it is also essential to analyze the outcomes for patients subjected to bilateral neck explorations based on IOPTH. Irvin reported that 70% of patients who had an elevated PTH despite a >50% fall in IOPTH would have unnecessary bilateral neck explorations. In those cases, if the remaining 3 glands are found to be grossly normal or equivocal, the surgeon is posed with a dilemma. If the surgeon performs a subtotal parathyroidectomy, he or she may be overtreating a patient who has already been cured—exposing that patient to the possibility of permanent hypoparathyroidism; or, if those glands are left in situ and they prove to be hyperfunctioning—for example, normalappearing 40-mg glands that were once 20-mg glands—then the surgeon has created a situation where a second operation would be more difficult due to fibrosis that would affect all of the glands left in situ. Two additional points:


Appendectomy is one of the commonest abdominal operation performed all over the world. Stump appendicitis is one of the uncommon complications of appendectomy. The diagnosis of stump appendicitis is delayed due to low index of suspicion by virtue of the fact that an appendectomy has already been done. The clinical presentation exactly simulates acute appendicitis. Contrast enhanced computed tomography is diagnostic. Completion appendectomy either open or laparoscopic is the mainstay of treatment. Awareness regarding the possible aetiology, diagnosis and management is essential for avoiding delay in the diagnosis.


The present study aims at assessing the impact of modelling textual structures on knowledge transfer. 20 students of English and American Studies of Graz University, who were on the linguistic level C1, took part in a reading test series in which they had to read a linear text on the topic "How does the human brain work?" The participants were tested on a recall and a reading comprehension task. In a pre-test the number of propositions had been determined by test readers. The experimental group was provided with a linear text (457 words) and an additional networked supertext. This supertext was created by applying the principle of cognitive plausibility to linear texts. The principle of cognitive plausibility refers to the ability to restructure one's knowledge in adaptive response to changing situational demand. The supertext restructured the original text by keeping the original question-answer pattern of the linear text and outlining its informational structure i.e. the macropropositions with their respective micropropositions in form of flow charts. The flow charts displayed the semantic structure of the text as a network of propositions. The control group only got the linear text. In accordance with the principle of cognitive plausibility, which so far has mainly been attributed to hypertexts, it was assumed that the supertext would facilitate the building of networked knowledge structures and the integration of new knowledge. The results of this pilot study suggest that the modelling of textual structures based on the principle of memory structures has a positive effect on both knowledge transfer and recall of propositions. A recognition posttest, which was conducted one week later, confirmed the results of the first test series. The group who had worked with the networked supertext also reached higher scores in the recognition test.


This article attempts to determine whether the hospitals of the Spanish Health System carry out evaluation activities of their public relations and communication campaigns and to establish their purpose. As secondary objectives, the budget for the evaluation was examined, as well as if the characteristics of the hospital evaluation process were adapted to Besson's postulates. A large sample of 300 Spanish public hospitals (response rate of 23.33%) was taken. The results indicate that hospitals carry out evaluations for the development of their duties, but that they do not allocate a large budget to evaluate their actions. This suggests that there is a concern to demonstrate the value of public relations practice in hospitals but that they are still at an early stage of a systematic adoption of a concrete form of model for the strategic use of evaluation.


The Nepheline-Syenitic Itarantim Batholith, located at the southern area of the Alkaline Province of South Bahia, shows a Rb-Sr age of 727 ± 49 Ma, has a pear shape, and is constituted by syenites and nepheline-syenites. Around this body there is an aureole of fenites. The magmatic syenites (pyroxene-syenites with nepheline and biotite-nepheline-syenites) show difuse contacts and are disposed along a NE-SW trend. The identified geochemistry evolution allows explaining the diversity of pyroxene-syenites through fractional crystallization. However, the biotite-nepheline-syenites, which evolve to lower SiO 2 contents and expressive by of Na 2 O (up to 9.6%) and Al 2 O 3 (up to 23.5%) increase reflect, probably, crystallization in an open system which is strong influenced by peralkaline fluids, as attested by the presence of fenites and enrichment of Zr (up to 5,100 ppm), Hf (up to 141 ppm), Th (up to 117 ppm), U (up to 74 ppm), Ta (up to 169 ppm) and Nb (up to 1372) in the dykes. The Nd and Sr values put the batholith rocks at the mantle array displaying an OIB geochemistry signature. The T DM model ages of 1.1 Ga are the same observed for the toleitic magmas emplaced in this area. These data suggest that the Itarantim anorogenic magmatism is controlled by a NE-SW geosuture, and represents the rift segment which corresponds wiler the West-Congo Craton, where the alkaline magmatism is expressed by ryolites, syenites and carbonatites.
