This article deals with Roberto Rossellini's famous Italian neorealist film, 'Rome, Open City' (Roma, città aperta, 1945), as well as Wolfgang Staudte's, 'Murderers Among Us' (Die Mörder sind unter uns, 1946), one of the best-known examples of realist rubble films from post-war Germany. Cultural heritage is a communal process and films, as cultural products, can act as unifying factors for a nation's viewers as well as for the architects of national identity. The article focuses on the ways in which these films can participate in the cultural heritage process and thereby affect the unity of a nation as a cultural heritage community. The cultural heritage process is maintained by using identity tools through which I analyse the cultural heritage built by post-war realistic films produced in two different nations.


The issue of the quality of life is multidimensional, for obvious reasons such as that human existence is multidimensional. A comprehensive study of quality of life should therefore be carried out in a multi-faceted manner. The main goal of the article is to present the opinions of young Rzeszow about the quality of life in the capital of Podkarpacie. The presented results come from two surveys conducted in 2015 and 2017 on representative samples of adult inhabitants of Rzeszow drawn from the database of population records made available by the City of Rzeszow. In order to ensure the representativeness of the sample, a systematic random selection with a hidden division into layers was used. The operation has been sorted out due to gender, housing estate and age of Rzeszow residents. The results of the Rzeszow Social Diagnosis of 2015 and 2017 have been analyzed in terms of various aspects of quality of life, such as communication accessibility, cultural offer and leisure time, safety, health care or issues related to city management.


BACKGROUND
Endoscopic submucosal dissection (ESD) is a minimally invasive procedure that allows curative treatment of early gastric cancer (EGC) in selected patients.

AIM
To report our initial experience with ESD.

MATERIAL AND METHODS
Analysis of prospective data from 16 patients aged 61 to 84 years, who underwent ESD between December 2011 and June 2014. Tumor type, operative time, hospitalization length, oncologic outcomes, complications and short-term follow up were registered.

RESULTS
En-block resection was achieved in all cases. The median operative time was 135 min (range: 50-320 min). Specimens' median size was 3.5 cm (range: 3-10). All the resections were R0. In 14 patients ESD was considered curative. In two patients, ESD was considered potentially non-curative due to the presence pathological risk factors for lymph-node metastases in the biopsy specimen. Both patients underwent laparoscopic gastrectomy with lymph-node dissection. There was one case of gastric wall perforation that was repaired by laparoscopic suture. There was no mortality. The median follow-up time was 15 months (range: 2-30 months).

CONCLUSIONS
ESD is a feasible and safe procedure in our institution with good results in this initial experience.


Jihoon Park (b.1973), a South Korean composer with over 500 compositions spanning multiple genres, is treasured in his motherland as the most noteworthy composer of his generation. This study provides an in-depth introduction of the gagok (Korean art songs) of Park to Western teachers and students of singing, discussing his compositional techniques and their application to the interpretation of his selected songs. Moreover, the introduction to International Korean Phonetic Alphabet (IKPA) to supplement the traditionally used International Phonetics Alphabet (IPA) serves as the foundation and model for further exploration into Korean art song literature by Western scholars.


This article analyzes the perceived stress during the COVID-19 pandemic in a situation of social detachment. A cross-sectional survey was carried out with 656 participants (both sexes) aged 18-85 years. Perceived Stress Scale (EEP-10) and questionnaire were applied, which were distributed through Google Forms on social networks. Data were analyzed on the Excell spreadsheet. It was observed 1) higher levels of EEP-10 in the younger population aged 18-40 years, with EEP-10 being Women> EEP-10 Men in all age groups, 2) Higher levels of EEP-10 were found in the age group 20 -30 years in women and 30-40 years in men. 3) Female population showed greater awareness of stress, ratified by the current scenario overloaded by work, domestic activities, attention to family members, fear of contamination in addition to modern female self-collection in a scenario of socioeconomic uncertainties. 4) Education level influenced adherence to preventive-restrictive measures. 5) There is a need for attention to the male and female population and special attention to the elderly in the face of psychological suffering. Such evidence raises the need for managers to establish public policies specific to these groups.

Tidal power has repeatedly been shown to be an unacceptably expensive energy source. The writers foresee a changing position resulting from a substantial increase in nuclear installations coupled with an associated dependence on pumped storage, plus escalating costs together with frequent concern over the supply of fossil fuels. The report shows how tidal power may be harnessed and combined with energy of thermal origin in a two-basin estuary pumped storage project, to give firm output and peaking potential with inherent hydro flexibility. The comparative simplicity of the total system, compactness and freedom from demands on land are distinct features.


The widening of the European Union and the emergence of budget airlines have brought with them a host of challenges to new member states like Latvia. A result of the economic polarization and its disproportionate effect on women is the explosion of sex tourism. East European destinations such as Riga have become more prevalent and accessible for sex tourists particularly from Western Europe. Despite this influx of sex tourists, the Latvian government has not formulated a policy response to manage sex tourism. Using Advocacy Coalition Framework (ACF) from the public policy literature, this project examines sex tourism related policies from the late communist period, starting in 1980 to the present and investigates how policy subsystems influence the shaping of policy in post-communist democracies. Process tracing and elite interviews uncovered two coalitions that formed around Latvian sex tourism, a feminist advocacy coalition and a business advocacy coalition. The data also revealed that these coalitions have remained intact despite the, at times, fluid membership of non-governmental organizations (NGOs) due to economic constraints. This paper also determined that there is no policy on sex tourism in Latvia despite the fact that many government representatives said that there were similar measures found in other policies such as prostitution, pornography, human trafficking, and adult entertainment thus, sex tourism was just a name for another type of similar activity. In addition to these findings, this project also demonstrates that ACF is applicable to mature but evolving policy subsystems outside of the United States and Western Europe. It also recognizes feminist organizations and the subtleties of actors involved in feminist policy research as key players in the policy subsystem that share beliefs and coordinate activity.


Objectives: To explore the prevalence of peripheral artery disease (PAD) in the adults in the Tibet Autonomous Region (Tibet) and Xinjiang Uygur Autonomous Region (Xinjiang). Methods: A stratified multistage random sampling method was used to obtain a representative sample from the resident aged 35 years old living in these two autonomous regions from 2014 to 2016. Ankle and brachial blood pressures were measured at rest in the supine position with validated digital monitors by trained staffs and ankle brachial pressure index (ABI) was calculated. PAD was defined as ABI ⩽ 0.9. Results: A total of 8529 residents were surveyed, 3654 in Tibet and 4875 in Xinjiang. The prevalence of PAD was 1.5% and 4.9% in Tibet and in Xinjiang, respectively. In Tibet, The prevalence of PAD was 1.5% in men and 0.7% in women, 1.2 in the urban area and 1.6 in the rural area, respectively. In Xinjiang, The prevalence of PAD was 4.7% in men and 5.2% in women, 6.8% in the urban area and 3.5% in the rural area, respectively. The PAD prevalence in the 35–44, 45–54, 55–64, 65–74 and ≥ 75 years old age group was 1.9%, 1.7%, 1.4%, 0.7% and 0% in Tibet and 3.8%, 4.6%, 5.5%, 7.8% and 8.1% in Xinjiang, respectively. Conclusion: In Tibet, there is a lower prevalence of PAD compared with Xinjiang. More effort may be needed to clarify this phenomenon.

The study was carried out to determine the extent of training needs of the fish farmers on integrated fish farming and to explore the relationship between the selected characteristics of the fish farmers and their extent of training needs on integrated fish farming (IFF). Four villages, namely North Gouari, South Gouari, Rajpur and Satrasia under Muktagacha Upazila (sub-district) of Mymensingh district were the locale of the study. Ninety fish farmers (out of the total of 300) were randomly selected as a sample of the study. Data were collected from the sample of fish farmers by using a pre-tested interview schedule through personal interview method during 15 to 30 April 2013. Pearson's Product Moment Correlation Coefficient (r) was computed to explore the relationships between the selected characteristics of the respondents and their extent of training needs on IFF. Training needs of the fish farmers on IFF was the dependent variable and selected characteristics of the respondents constituted the independent variables of the study. The highest proportion (56.7 per cent) of the respondents had high training needs while 42.2 per cent of the respondents had medium and only 1.1 per cent had low training need on IFF. The 'training needs for selection of diseases free seed and species' ranked first followed by 'training needs for ways of diseases control'. Sequentially 'training needs for breed selection' was third, 'training needs for stocking density of fish species' was fourth 'training needs for preventive measures of diseases' was fifth and 'training need for techniques of egg collection' was last in the rank order. Correlation analyses indicated that five characteristics of the integrated fish farmers, namely years of schooling, organizational participation, communication exposure, social mobility and knowledge with IFF had significant positive relationships with their extent of training needs on IFF. The household size, age and annual income showed no significant relationships with their extent of training needs on IFF and showed negative trend. The main problems on IFF were unavailability of quality seed and species, lack of financial support, lack of knowledge on species selection, lack of marketing facilities, lack of knowledge on fish processing and preservation. The extension service providers should arrange more training and motivational campaign for the fish farmers on IFF. DOI:  http://dx.doi.org/10.3329/pa.v24i1-2.19171 Progress.

Knowledge management is the concept that can turn the tide in the context of market competitiveness and competitive advantage in any area of organised activity. The benefit knowledge management may bring to an organisation is not tied to human organisations only though, as artificial agents, initially created as an imitation of humans, can benefit from organised and accessible useful knowledge as well. This paper covers a number of conceptual modelling examples following the theoretical settings presented within the paper. These examples emphasise the importance for clear and nonbiased definition of knowledge management concepts and contents, with the goal of fostering knowledge sharing culture in organisations, as well as creating knowledge accessible to artificial agents and applicable to various situations where artificial intelligence can be of service utilising the concept of systems comprising agents both human and artificial. Therefore the main quest of this paper is to argue towards demonstrating the benefits of conceptual modelling in knowledge management using domain specific and general cases, respecting the concept of fair argument, thus providing reasoning both in favour and against the basic topic of this paper. The main method of achieving the set goal is based on theoretical overview and analysis of the proposed cases and already published research. The results that are presented in this paper are a good addition to both the research areas of knowledge managements and multiagent systems. The combination is a welcome addition in the modern world where distributed computing is gaining power and informatisation is a global and omnipresent process. Emphasising the importance of developing systems that help bridge the communication between human and artificial agents, especially if they happen to be working in the same organisation, is an interesting problem with rising significance, since artificial agents are increasingly present in historically human organisations. An interface fostering the communication process between human and artificial agents that suppresses the necessity for direct interaction of the included entities, but increases the importance of knowledge modelling and management towards ef


Intensity-based 2D/3D registration is a key technique using digitally reconstructed radiographs (DRRs) to register the preoperative volume to the patient setup during the operation. Although DRR-based method provides a high accuracy, the small capture range hinders its clinical use. In this paper, such problemwas addressed by a robust and fast initializationmethod using a two-level scheme including automatic tracking-based initialization (Level I) andmultiresolution estimation based on central-slice theorem and phase correlation (Level II). It provided almost optimal transformation parameters for intensity-based registration. Experiments using a public gold standard data set and a spinal phantom have been conducted.Themean target registration error (mTRE) was limited in the range from 2.12mm to 22.57mm after tracking-based initialization. The capture range based on level II only was 20.1mm and the mTRE in this capture range was 2.92 ± 2.21mm.The intensity-based 2D/3D registration using proposed two-level initialization achieved the successful rate of 84.8%with the average error of 2.36mm.The experimental results showed that the proposedmethod yielded the robust and fast initialization for intensity-based registration methods. In a similar way, it can be applied to other registration methods to enable a larger capture range and robust implementation.


Ribosomes, the universal cellular organelles catalyzing the translation of genetic code into proteins, are giant asymmetric riboprotein assemblies with a striking architecture and inherent mobility, enabling their function as ribozymes how place their substrate in stereochemistry suitable for peptide bond formation and substrate mediated catalysis. As the main player in a fundamental cell process, ribosomes are targeted by many antibiotics. Structures of over a dozen antibiotics complexes, obtained by using eubacterial ribosomes suitable to serve as pathogen models at clinically relevant concentrations, showed that although theoretically the giant ribosome offers numerous binding opportunities, ribosomal antibiotics bind to a single or a few binding sites; that most antibiotics interact primarily with riboso mal RNA and cause minor conformational changes; that minute structural differences, scattered in various ribosomal locations, are responsible for antibiotic selectivity; that the properties of the antibiotic-binding modes are dictated by species-specific binding pocket composition and conformation, the functional state of the ribosome, and the drugs chemical nature; that resistance to ribosomal antibiotics is acquired mainly by target alterations but in a few cases, the antibiotic chemical moieties are modified; that the primary action of most antibiotics that induce significant local or allosteric conformational alterations is to inhibit functional activities rather than to merely block vital locations; and that most proteins that interact with antibiotics are involved in dynamic aspects of ribosomal function. Although a precise understanding of all processes associated with antibiotic action is still incomplete, the current findings justify modest optimism and it appears that the elucidation of the common principles, combined with the genetic, structural, and biochemical investigations should lead to structure-based approaches for devising modifications of existing antibiotics as well as in the design of novel potent anti-infective drugs.


With the success of Beijing for the bid of 2008 Olympic Games,Qingdao becomes the only partner city to hold the Olympics,and Fushan Bay will be the race water of sailing,which provides a good opportunity for the development of sports travel industry in Qingdao.For various reasons,the sports travel of Qingdao begins early but develops slowly.The problems lie in the low exploitation and use of sports travel resources,lack of marketing and promotion,poor equipment of service and facilities,short of human resource with professional skill,and little studies of sports travel theory.The paper tries to find out the problems,draw references from former host cities of Olympic Games,and put forward the basic countermeasures of sustainable development of sports travel.

This paper aims to determine the thermal conductivity for two types of functionalized carbon nanotubes (FCNT "Taunit M") nanofluids. FCNT1 and FCNT2 have been used to enhance the thermal conductivity of nanofluids. Six concentrations of 0.01, 0.02, 0.03, 0.05, 0.07, 0.1 wt.% loading of FCNT1 and three concentrations of 0.01, 0.05, 0.1 wt.% loading of FCNT2 have been used in this experiment. The experiments were achieved at temperatures 40°C. The technique for measuring thermal conductivity was described and manufactured at Tambov State Technical University. As a result of the study, the effect of increasing concentrations of FCNTs in the aqueous medium on thermal conductivity was presented. The relationship was nonlinear in FCNT1. The maximum enhancement thermal conductivity was 11.6 and 7.1% loading FCNT1 and FCNT2 respectively, which achieved at a weight fraction of 0.05 and 0.1 % respectively. Finally, the latest researches in this field were presented for comparison in the results obtained.


ABSTRACT: The sensitivity of antibody screening carried out by reacting a serum with random test cells depends on the probability of a given antigen being present in the cell panel. This probability (p) is defined by the formula p = 1‐(1‐f)n where f is the antigen phenotype frequency and n the number of reacted random cells.


Background and objective: Research has shown that diffusion-weighted magnetic resonance imaging (DW-MRI), one of the functional MRI techniques, can be utilized to evaluate renal function; however, more investigation is needed to understand its potential and capacity. The present study was carried out in order to evaluate the relationship between apparent diffusion coefficient (ADC) values of renal parenchyma and different stages of chronic kidney disease and to compare it with serum creatinine and estimated GFR among patients who referred to Rizgary Teaching Hospital in Erbil, the Kurdistan Region of Iraq. Materials and Methods: The present experiment was an analytic cross-sectional study that was carried out from November 2017 to April 2018. In so doing, 12 individuals (control group) and 38 patients (patient group) diagnosed with known chronic kidney disease (CKD) were selected. After they had undergone magnetic resonance imaging of the upper abdomen, the patient group subjects were classified into different stages of CKD based on estimated glomerular filtration rate (eGFR) calculated using chronic kidney disease epidemiology (CKDEPI) equation. Both control and patient groups underwent DW-MRI at b values of 40, 400, and 800, and ADC values were calculated for both groups. Afterwards, the control and patient groups were compared regarding their ADC values. Results: The results of the present study revealed a significant inverse correlation between ADC values and serum creatinine in the patient group. Also, there was a strong positive correlation between ADC and eGFR in the patients with CKD. Moreover, the patient group had a significantly lower mean ADC compared to the control group. Conclusion: The observed correlation between ADC values and serum creatinine and eGFR in the patients under investigation in the present study indicated that the presence and degree of renal dysfunction can be determined through ADC values.


Abstract : The error correction model for a vector valued time series has been proposed and applied in the economic literature with the papers by Sargan (1964), Davidson et al. (1978), Hendry and von Ungern-Sternberg (1981) and has been given a formal mathematical treatment by Granger (1983). He introduced the notion of cointegratedness of a vector process and showed the relation between cointegration and error correction models. This paper defines a general error correction model, that encompasses the usual error correction model as well as the integral correction model by allowing a finite number of error correction terms which correspond to linear combinations of the vector process that are integrated of different order. It is shown that this structure is inherent in the model if it is given in autoregressive form or moving average form by exploiting the singularity of the matrix function that defines the model. The theory is applied to some examples discussed by Davidson (1983) and Harvey (1982). (Author)

The County Energy Internet (CEI) is an emerging trend of energy utilization under energy transition, which integrates multiple energy resources and microgrids (MGs), and can promote system economy, reliability as well as efficiency. Nevertheless, the operation of the CEI faces challenges and opportunities due to the distinct operational characteristics of subsystems and the privacy-preserving issues among entities. In this paper, a decentralized stochastic operation method is presented to achieve energy and reserve co-optimization and to mitigate the impact of intermittent photovoltaic. Besides, reserve capacity of every independent energy autonomy is determined by chance-constrained programming (CCP), and these probabilistic constraints are transformed into deterministic counterpart based on probabilistic prediction results. Moreover, a decentralized coordination algorithm based on analytical target cascading (ATC) is proposed to coordinate the CEI operator and MG operators with least information sharing. Case study on a CEI with a modified 15-bus power distribution system and a 6-bus district heating system has validated the proposed method.


1 The vasoconstrictors epinephrine and norepinephrine added to the local anaesthetics lidocaine and mepivacaine do not diminish, but rather increase, the frequency of changes in pulse rate and blood‐pressure level during surgery. One possible exception is for epinephrine when the patient during surgery is exposed to reflex stimulation of the vagus. This conclusion is based upon a large series of recorded clinical anaesthesias. 2 Oxygen consumption and blood‐sugar level in the patients rise when the vasoconstrictors epinephrine and norepinephrine are added to local anaesthetics in major anaesthesias. This conclusion is based on a double‐blind study.


A series of solvent systems was developed for CCC to separate mixtures containing variable amounts of artemisinin, artemi-sitene, and arteannuin B. To purify multigram quantities of artemisinin by CCC it was necessary to maximize the amount of a mixture that could be dissolved in a fixed quantity of the solvent mixture.


THE COMBINATION of widespread sclerosis of the pulmonary arterial tree and cardiopulmonary failure has been the source of repeated discussions during the past 60 years. 1 Brenner's extensive reviews 1e have served to emphasize the complexities of this combination. Particularly enigmatic has been the pathogenesis of primary pulmonary vascular sclerosis. In the present communication we wish to record two additional cases displaying widespread thrombotic or embolic masses within small pulmonary arteries and pulmonary vascular sclerosis of a sufficient magnitude to effect cardiopulmonary failure (Ayerza's syndrome). Human cases of this type, which have been periodically recorded, merely indicate the association of thrombi or emboli and the vascular lesions. The experimental intravenous injection of small embolic masses, on the other hand, by evoking a similar vascular sclerosis indicates a cause and effect in this relationship. In a separate report 2 the experimental production of pulmonary vascular sclerosis in the rabbit by means of embolie masses


In the fall of , Adolf Hitler, with the support of the German medical community, authorized a secret, and now largely forgotten, initiative called the "T-" program, named after the Berlin address of the program's coordinating center (Tiergartenstrasse ). The plan was to perform "euthanasia," or mercy killings, of persons that the Nazi party considered to be Lebensunwertes Leben, which translates as "life unworthy of life" (another commonly used term was Unnütze Esser or "useless eater.") These persons were residents of public and private hospitals, psychiatric institutions, and nursing homes who met certain criteria, including persons who had been diagnosed with schizophrenia, dementia or other psychiatric and neurological disorders that were considered incurable, people who had been committed on criminal grounds, and anyone who had been at the institution for more than five years. People identified by physicians were then moved to special centers, where they were killed using newly developed poison gas procedures, and their remains disposed of using mass cremation. Although the T- program was not limited exclusively to people that we would now consider to have severe mental illnesses, it is clear that such individuals made up the bulk of those targeted. Estimates for the total number of persons killed under the T- program vary, and range from roughly , to ,. It is estimated that roughly threequarters of Germans with a diagnosis of schizophrenia were killed under the T- program.


AbstractInitial documentary research undertaken by Lancaster University Archaeological Unit (LUAU) in 1995 for 'The Hotties Science & Arts Centre Ltd.' (hereafter The Hotties) revealed the existence of a former iron foundry on part of the development site for the wider The World of Glass Project which will portray the technical development and heritage of the glass industry in St Helens. Between January 1996 and November 1997 LUAU were commissioned by The Hotties to undertake a range of archaeological works resulting in the excavation of a smithy complex. Known as the St Helens Iron Foundry, and latterly owned by the Daglish family, the site had an international reputation for the casting and building of steam pumping and winding engines for the mining industry. It was particularly successful during the mid-19th century producing locomotives and bridges for the expanding railway network. The foundry was in continuous production from 1798, until its decline and eventual demolition in 1939.


Analytical models able to predict the tool wear can provide companies instruments to optimize the cutting processes. The focus of this thesis is to accomplish a study of the tool wear process in the turning process of superalloys, including its dependence on multiple factors related to the characteristics of the workpiece and machinery used for turning. As a natural extension of this study we propose the application of some statistical and machine learning techniques to address the prediction of the tool wear. Data corresponding to different tests carried out as part of the European project called Himmoval is used. The process of prediction involves selecting features from the variables acquired by different sensors that characterize the machining process. Additionally, several machine learning algorithms are implemented and applied to analyze the data from the wear experiments. Among these algorithms, Gradient Boosting Regressor predominates over the rest of regression methods evaluated.


The article analyzes the actual topic -- a tool for reducing of uncertainty in strategic management decisions in the "digital economy". The tasks solved in the article are to concretize the concept of "digital economy" and substantiate the digitalization of economic information as a tool for more effective management of the economy. Methods for organization of management and reduction of uncertainty about the object of management by digitization of additional information are used. The novelty of the article is the proposal of a methodological tool that provides the reducing of an uncertainty when choosing a most rational management decision through the digitization of information. The basic concepts related to the economy, "digital economy" and information in the framework of statistical theory, are analyzed in the article. The definition of "digital economy" and recommendations on the organization of information management through, inter alia, its digitalization as a determining factor to reduce uncertainty when choosing a more rational management decision, are proposed. The relevance of the introduction of human-machine interaction technologies for the collection and analysis of information, which is needed for making strategic decisions in the conditions of digital transformation of enterprises, is shown. Concluded that it is possible to increase the probability of implementing of a decision that meets the criteria of optimal choice by using of information on a certain program for reducing of uncertainty and achieving the goal of the strategic management.


Nelson Pereira dos Santos's Rio, 40 graus  (1955) was censured and had its release  forbidden  for showing the slums of Brazil's former capital, Rio de Janeiro. Through the analysis of discourses in favor and against the movie, as well as some of its sequences, this article aims to reflect on the dispute regarding the representation of the city – and of the country –, questioning the idea of "golden years".


In an attempt to improve on the properties of PEDOT (poly(3,4-ethylenedioxythiophene)) as a stable, conducting, and transparent coating we synthesized four different alkoxy-substituted poly(thienylene−vinylene)s, 1−4, using the Stille coupling reaction. The oligomers and polymers obtained were characterized and their NIR−vis absorption spectra were measured as a function of doping, both electrochemically as films and chemically in solution. Similar spectra of PEDOT films were gathered for comparison. In PEDOT a change in doping level does not change the energies of the absorption bands, while for the other polymers the bands shift markedly and the NIR peak at high doping level lies at a higher energy. The polymers 1−4 are much less suited for the intended coatings than PEDOT. Possible reasons for this are discussed.


To achieve near net forming of complex Cf/ Mg composite parts,liquid-solid extrusion following vacuum pressure infiltration process was proposed based on analysis of liquid infiltration preparation technology,and relevant forming device was developed by which 2D carbon fiber felt reinforced magnesium matrix composite complex parts were fabricated.

The shape of the complex parts is complete and consistent with the design,the composite material was dense and the carbon fibers were uniformly distributed in the composite.


This research describes the pragmatic meaning of verbal and nonverbal language of Sundanese people in Sindangkasih District, Ciamis Regency, West Java. This research is a qualitative research using ethnopragmatics. That is, verbal and nonverbal politeness of Sundanese people can be done through speech acts that use kinesthetic nonverbal language (facial, gestural, and postural). The data source of this research is routine activities carried out by Sundanese people in Sindangkasih Subdistrict. The data in this study are verbal and nonverbal languages that contain politeness. The technique of collecting data in this study was to adapt the ethnographic method and use the method of listening. The data analysis technique of this study uses a flow model consisting of data reduction, data presentation, drawing conclusions and verification. The results showed that the pragmatic meaning of verbal and nonverbal politeness of Sundanese people was manifested through kinesthetic nonverbal language, namely nonverbal facial language (facial expressions / facial expressions); gestural (eye movements, head movements, and hand movements); and postural (movements of all limbs, such as bowing, standing upright, leftward, and rightward). Keywords: Verbal language, nonverbal language, and politeness

The article outlines and examines the EC Commission's proposal for a directive of the European Parliament and the Council on market access to port services with a main focus on cargo handling in order to increase competition within ports. The proposal suggests that where the number of providers of cargo handling has been limited, a competent authority shall take the necessary measures to ensure a transparent and objective selection procedure, through tendering, using proportionate, non-discriminatory and relevant criteria. Providers of cargo handling shall be selected for a limited period of time to be determined in accordance with the significance of investments especially in moveable or immoveable assets. It turns out that the selection procedure through tendering is not very efficient. Investments in maritime infra- and superstructure could be endangered. The author would recommend applying the essential facility doctrine to enhance competition between cargo handling providers within a port.


Introduction: Soft palate is a fibromuscular portion constituting the back of roof of the mouth which is essential for phonation, deglutition, respiration and velopharyngeal competence.Objective: To study various morphologies of soft palate, difference in proportion of each type and their differencesamong gender and agegroups in Nepalese sample.Materials & Method: A retrospective study was conducted on patients seeking orthodontic treatment. 263 lateral cephalograms were classified on the basis of radiographic appearance.

Pearson chi square and descriptive statistics were performed and level of significance was set at p<0.05. Result: In the order of occurrence; rat tail type of soft palate was most prevalent followed by leaf type, butt type, straightline, crooked type and S shaped. There was no significant difference between male and female subjects (p=0.338) and through age groups (p=0.998).Conclusion: The study highlights various types of soft palate present in Nepalese sample which will help as a reference for research pertaining to cleft palate/ velopharyngeal closure and in obstructive sleep apnoea syndrome in Nepalese population


Objective: Marfan syndrome is a genetic disorder affecting connective tissues due to a mutation in the fibrillin 1 gene (95%) than leads to upregulation of the transforming growth factor beta (TGF-&bgr;) family. The main cause of mortality in these patients is aortic dissection. Medications to lower blood pressure are used to decrease the aota wall stress. Losartan acts by lowering blood pressure and attenuating TGF-&bgr;-induced signaling; it is converted by hepatic cytochrome P450 enzymes to an active metabolite E3174. CYP2C9*2 or *3, CYP3A5*3 and CYP3A4*22 leading to losartan poor metabolism phenotypes. The objective of the present study was to assess the roles of the individual and combined effect of CYP2C9*2 and *3, CYP3A4*22 and CYP3A5*3 in Marfan normotensive patients treated with losartan to prevent cardiovascular complications. Design and method: Genomic DNA were isolated from peripheral blood cells. Genotypes were determined by Real-Time PCR using LightSNiP (TIB-MolBiol). Statistical analysis was conducted by R package "SNPassoc". Results: The study enrolled 182 patients (93 males). The median age was 31yrs (range 2–71yrs). All patients received losartan (12.5 to 100 mg/day) on the base on the tolerability. CYPs *1 identifies reference allele. CYP2C9*2 allele is present in 42 (23.1%) patients in heterozygosis and in 5 (2.7%) in homozygosis. 26 (14.3%) patients carrying CYP2C9*3 allele in heterozygosis and 2 (1.1%) in homozygosis. CYP3A4 *22 are present in 21 (11.6%) and 2 (1.1%) of cases in heterozygosis and omozygosis, respectively. The heterozygosity and homozygosity status of CYP3A5*3 was observed in 25 (13.8%) and 156 (86.2%) patients, respectively. All variants are in Hardy-Weinberg equilibrium. No difference in tolerated dose of losartan was observed for all functional variants evaluated. Age and body weight were always considered as covariates in the multivariate regression since they resulted to significantly affect the daily dose of losartan. Conclusions: At present, there is insufficient evidence to support the use of genetic polymorphisms as predictors of the right dose of losartan in normotensive marfan patients. Further studies need to definitively exclude the pharmacogenetics prediction of losartan response in patients affected by the Marfan Syndrome.


What do you expect when you or a loved one needs treatment in an ED? Timely and expert care. It's easy to cast aspersions when delays occur or wait times are long. What's important to appreciate is that the ED is a dynamic system that represents the proverbial canary in the coal mine. It's the place where challenges impacting the healthcare system and the larger community as a whole meld and contribute to the milieu as well as the outcomes. ED operations are like an intake and output equation: too much intake without balanced output creates an overload situation, and failure is likely. Imbalances in seemingly unrelated parts of the healthcare continuum can have a profound impact. For example, lack of timely primary or urgent care access in a community can drive more patients to the ED to have unmet health needs addressed. If hospital inpatient length of stay increases due to high patient acuity, system issues, or a lack of enough postacute beds or services in the community to enable timely discharges, hospital occupancy rises. The net result is that newly admitted patients board in the ED while they await inpatient beds. Having inpatients occupy ED rooms effectively shrinks the size—or functional capacity—of the ED. That same ED now has to care for incoming patients in a much smaller footprint as well as the higher acuity inpatients who haven't left yet. If the ED isn't effectively decompressed, staff workload, ED wait times, and crowding can increase dramatically. Unlike most other healthcare settings that limit patient census by their bed count or hours of operation, the ED has no cap. Patients of all acuity levels keep coming 24 hours a day, 7 days a week—sometimes in surges—and patients who present for care can't be turned away under federal law. Addressing issues that cause ED crowding is critical; efficient ED operations are fundamental to a region's emergency preparedness infrastructure. Seemingly small, local actions can make a positive impact. For those who work on an inpatient unit, please support patient safety by developing rapid processes to accept ED admissions without delays. Doing so will make lifesaving rooms more readily available. You never know who might need an ED room next...


Background: The advanced activities of daily living (AADLs) in old age is a key indicator of the mobility domain for the intrinsic capacity of older adults living in the community; for this reason, it is relevant to know the prevalence and risk factors related to performing fewer AADLs in different populations. Aim: To determine the prevalence and factors associated with the ability to perform AADLs in older adults reported in the Mexican Study of Health and Aging (MSHA 2018). Methods: A secondary cross-sectional analysis of the MSHA 2018 data was carried out, including a convenience sample of 6474 subjects ≥ 60 years of age, for both sexes, without cognitive deficits. Nine questions related to AADLs were selected from the database. Multiple logistic regression analysis was performed to determine factors associated with <3 AADLs, including sociodemographic, lifestyle, and health status factors. Results: The prevalence of the ability to perform <3 AADLs was 63%. Age is the most important risk factor for <3 AADLs, which increases by the decade, followed by sedentary lifestyle (OR = 2.15, 95% CI: 1.91–2.42, p < 0.0001). Conclusions. Our findings suggest that age, schooling, urban residence, sedentary lifestyle, and comorbidity are the main risk factors for <3 AADLs in older Mexican adults.


Image destriping is necessary due to sensor-to-sensor variation within instruments. This has most often been done by assuming that each sensor views a statistically similar subimage, and a histogram of each sensor's response is made to match the overall histogram. Histogram matching shows sensitivity to violations of the similarity assumption. An alternative algorithm is suggested which matches the gain and offset of each sensor to typical values, and which is resistant to the effects of outliers. Tests on a sample image show the moment matching algorithm reduces the variance between sensors to a greater degree than histogram matching.


We tend to view type 1 diabetes mellitus as a chronic autoimmune disease with a preclinical phase that usually lasts for a number of years.1 The classic symptoms of type 1 diabetes — hyperglycemia ...


Ice-coupled waves travelling beneath solid ice sheets experience decay arising from both scattering (reflections by inhomogeneities) and damping (a consequence of the viscoelasticity in the sea-ice and energy loss in the water). Scattering and damping have been examined in isolation but rarely together, which is necessary if a model is to simulate reality accurately. This deficiency is addressed herein. We describe a model that assimilates these mechanisms, which is used to reproduce waves under two dimensional ice sheets of variable thickness. Damping is more significant for lower period waves and scattering causes a reduction in the observed decay rate.


This trend research article accounts on a unique interdisciplinary collaboration of two highly creative personalities: psychologist Mihály Csikszentmihályi, Distinguished Professor of Psychology and Management at Claremont Graduate University and poet Géza Szőcs, President of the Hungarian Pen Club. Guidelines of Flow architecture were set: a new building should create dynamic spaces, sustain departure and return, bridge timeframes, create balance between lights and colors, and contain elements that surprise people.


Employing a thermodynamic interpretation of gravity based on the holographic principle and assuming underlying particle statistics, fermionic or bosonic, for the excitations of the holographic screen leads to modified Newtonian dynamics (MOND). A connection between the acceleration scale ${a}_{0}$ appearing in MOND and the Fermi energy of the holographic fermionic degrees of freedom is obtained. In this formulation the physics of MOND results from the quantum-classical crossover in the fermionic specific heat. However, due to the dimensionality of the screen, the formalism is general and applies to two-dimensional bosonic excitations as well. It is shown that replacing the assumption of the equipartition of energy on the holographic screen by a standard quantum-statistical-mechanics description wherein some of the degrees of freedom are frozen out at low temperatures is the physical basis for the MOND interpolating function $\stackrel{\texttildelow{}}{\ensuremath{\mu}}$. The interpolating function $\stackrel{\texttildelow{}}{\ensuremath{\mu}}$ is calculated within the statistical mechanical formalism and compared to the leading phenomenological interpolating functions, most commonly used. Based on the statistical mechanical view of MOND, its cosmological implications are reinterpreted: the connection between ${a}_{0}$ and the Hubble constant is described as a quantum uncertainty relation; and the relationship between ${a}_{0}$ and the cosmological constant is better understood physically.


In this article we establish some product identities for balancing and Lucas-balancing numbers, using the telescoping summation formula and inverse hyperbolic tangent function.


With the increasing threat of noise pollution due to urbanization, its effects on many organisms are now being studied. Past studies have shown that anthropogenic noised tends to increase the vigilance of an organism (i.e. Rabin et al. 2006), but few have demonstrated the specific masking capabilities of such noise. This study aimed to determine whether traffic noise had the ability to mask alarm calls of the eastern chipmunk (Tamias striatus) as reflected in vigilance behavior. Chipmunks were video taped while foraging during silence and the playing of traffic noise, alarm calls, and alarm calls with traffic noise. It was expected that the chipmunks would show a slightly increased rate of vigilance in the presence of noise, and an extremely elevated level of vigilance during alarm call playbacks. Residence time should also have increased due to the more time spent being vigilant. When the traffic noise and alarm calls were played in tandem, the noise should mask the alarm calls, and therefore the chipmunks should not show a significant increase in vigilance. The results of this study show that traffic noise does have the potential to mask alarm calls. Chipmunks showed a significantly greater rate of vigilance behavior during the alarm call playback (one-way ANOVA, F0.05,3,66=7.78, p=0.00016; Tukey's HSD, p<0.001, p=0.015, p=0.015) than any of the other treatments, which were all statistically equivalent (p=0.95, p=.1, p=0.91). There was no significant relationship between treatment and residence time (one-way ANOVA, F0.05,2,22=2.69, p=0.09). This is the first study to demonstrate that traffic noise can mask alarm calls, and this could have serious ramifications on the ability of organisms to detect predators in noisy environments. Introduction. Urban expansion is making noise pollution an increasingly popular topic of ecological research (reviewed by Slabbekoorn and Ripmeester 2008). Anthropogenic noise has the potential to mask biological sounds used by the organism for survival and reproduction, which could ultimately affect the fitness of the organisms inhabiting the affected area. Animals living in noisy areas may have difficulty hearing mates, offspring, predators, or prey due to masking effects (Barber et al. 2010). Although conservation biologists have only recently started investigating how anthropogenic noise affects wildlife, numerous studies have already chronicled the behavioral changes that noise has caused in various organisms. In marine systems, noise pollution from boat traffic and military operations has become an especially significant concern due to its effects on mammal communication. Foote et al. (2004) found that killer whales increase the duration of their calls in the presence of boat traffic, and studies have found a similar response of


In the last few years, we have observed a significant boot in copper prices which has been accompanied with a larger share of speculators who trade in this market based on reasons different to production or processing of the metal. In fact, long positions of speculators increased from 25% in 2002 to 47% in 2005. In this work, we build a comprehensive weekly database with positions of noncommercials agents in the copper futures market for the period 1992 -2006, to analyze its association with the level and volatility of copper prices. Our results support the view that speculators do not have permanent effects on the level of prices, although they may play a significant role in transitory movements of prices. Once we explore the role in the amplitude of price fluctuations, we find a positive but no significant effect of speculators´ positions in the volatility. Based on the results, it is advisably to follow the positions of speculators to improve the understanding of short-term variations in copper prices.


Background, connotation and extension are three essential factors in correct reading comprehension. Background has great effect both on the acquisition of source materials and the emotions of works. Meanwhile background has the features of contingency and dual ways. The grand glamour of woks lies in indirect connotation, which has single and complex forms .Grasping the measurement of extension is the key element of right comprehension of the woks' practical and historical significance.


Decades of satellite, airborne, and ground observations clearly show increased melting of glaciers and ice sheets, declines in sea ice, and decreasing spring snow cover. This increased melting of cryosphere cover makes Earth more absorptive of sunlight and moves enormous volumes of stored water from frozen state to liquid, raising sea level and changing water availability to large populations. However, the distribution of forcings controlling this accelerated melting is poorly known.


We investigate the properties of a static, cylindrically symmetric Majumdar–Papapetrou-type solution of Einstein–Maxwell equations. We locate its singularities, establish its algebraic type, find its asymptotic properties and weak-field limit, study the structure of electrogeodesics, and determine the mass and charge of its sources. We provide an interpretation of the spacetime and discuss the parameter appearing in the metric.


Abstract We introduce an intrinsic filtration to the magnitude chain complex of a metric space, and study basic properties of the associated spectral sequence of the magnitude homology. As an application, the third magnitude homology of the circle is computed.


Keynes formulated the idea that consumer goods prices are independent of prices for new investment goods. This notion was rejected by Kahn, who felt that an independence of this sort stems from certain highly specific hypotheses. Unfortunately, after corresponding with Kahn, Keynes ended up by accepting this criticism. A few years later, Hicks resurrected Kahn's viewpoint when commenting upon the Treatise. The purpose of the present text is to demonstrate that Kahn-Hicks's criticism is incompatible with the central message of the Treatise, since it implies an equality between investment and savings, asserting their identicalness, whereas for Keynes this equality is a condition of monetary equilibrium.

Background:  In this study, we evaluated the ratio of the cuff diameters of the Microcuff paediatric tracheal tube (Microcuff PET, Weinheim, Germany) to fluoroscopically measured internal transverse tracheal diameters in children from birth to adolescence.


Verification testing of a solar collector was undertaken prior to its operation as part of an industrial process heat plant at Capitol Concrete Products in Topeka, Kansas. Testing was performed at a control plant installed at Sandia National Laboratory, Albuquerque, New Mexico (SNLA). Early results show that plant performance is even better than anticipated and far in excess of test criteria. Overall plant efficiencies of 65 to 80 percent were typical during hours of good insolation. A number of flaws and imperfections were detected during operability testing, the most important being a problem in elevation drive alignment due to a manufacturing error. All problems were corrected as they occurred and the plant, with over 40 hours of operation, is currently continuing operability testing in a wholly-automatic mode. R.J.F


The authors have conducted histopathological studies on various types of the avianleukosis complex"9?"). The materials used for these studies were morbid chickens wlaichhad occurred spontaneously in Japan since 1950.In this paper, histopathological investigation was carried out on 78 chickens whichwere believed to have been infected naturally with a disease identical with what hadbeen known by the name lVareks disease and broken out on 25 poultry farms mainly in1969. The birds were layer chickens of foreign-produced strains from 37 to 191 days ofage. For histological examination, as many samples as possible were collected fromvarious parts of organs, including the central and peripheral nervous systems and theeyes. Furthermore, the authors reexamined the specimens dealt with in their previousreports, part II (neural lyrnphomatosis)20) and part III (ocular lymphomatosis)21).In the present studies, the following particulars were examined: the character ofproliferating cells, the distribution and severity of lesions, and the relationship betweenthe termination of the birds used and the type of proliferating cells. The proliferatir-ugcells were Iymphocytic and divided into three types, large, medium, and small, chieflyon the basis of size. The main Iesion of the disease in question was composed of pro-liferating cells. Such cells were also present frequently in blood vessels. Lesions weredistributed widely in organs, including the central and peripheral nervous tissues, eyes, mesenteries, and adipose tissues, located in the whole body. The lesions were variablein severity. Generally speaking, this disease had a tendency to be more malignant when pro-liferating cells of large and medium sizes were predominant in the cellular element ofeach lesion.From the findings thus obtained, especially those on the character of the proliferat-ing cells, it was considered that the disease dealt with in this paper should be called"lymphatic leukemia", and that "neural lymphomatosis" and "ocular lymphomatosis", which had been described in the authors previous reports, parts [120) and [1121), shouldbe regarded as diseases of the same category as lymphomatic leukemia. Moreover, it wasthought that "avian visceral lymphomatosis", which was described in the authors pre-vious reports, parts I") and VI3), should be called "germ cell sarcoma".


This paper presents a procedure for analyzing the characteristics of alternative systems for the transportation of bulk cargoes. The included features of transportation systems are the basic part of a set of criteria for the selection of the best variety. Besides the standard systems the new system of trolley cars has been included as well, and its features essential for the ranking of variants have been highlighted. Out of a larger number of benefits and disadvantages of the system, the basic ones have been isolated that satisfy the evaluation of the effects of introducing the new system.


DEAD-box RNA helicases, which function as the RNA chaperones, are involved in RNA metabolism,including pre-mRNA splicing,ribosome biogenesis,RNA degradation and gene expression. In addition,they also play important roles in plant development and stress tolerance. A DEAD-box homologous protein was selected from the NCBI database by means of program of homologous alignment according to the published DEAD-box protein in Arabidopsis thaliana and maize and named SlDEAH1,then the specific primers, which being used to amplify the cDNA sequences of SlDEAH1 from wild type tomato AC+ +,were designed according to the DNA corresponding sequences. Bioinformatics analysis,expression pattern,stress and hormone treatments were used to study the DEAD-box gene SlDEAH1. The results showed that the open reading frame of SlDEAH1 was 2 073 bp,encoding 690 amino acid residues. In the protein of SlDEAH1,9 conserved motifs were found to be essential for the helicase activities such as ATP binding,ATP hydrolysis and RNA binding. RT-PCR expression pattern analysis showed that SlDEAH1 may play important roles in sepal and leaf development and fruit ripening. High temperature,low temperature,dehydration,wounding and salt stress induced the expression of SlDEAH1 in different degrees in leaves,but its expression in roots was obviously inhibited by salt stress. Furthermore,the expression of SlDEAH1 was also induced in different degrees by ABA,ACC,IAA,GA 3,MeJA and ZT,and the inductive effect of ABA was the most obvious. These results lay a foundation for further study on the physiological function of SlDEAH1 in the development and stress response of Solanum lycopersicum.

The most of the ordering approaches are derived from the practice of the production and life, and these approaches ensure relatively good packing result. In view of rectangular packing problem, this paper presents an ordering approach which is based on evaluative function. By the analysis of this evaluative function, some properties of this ordering approach are obtained. And through contrast experiment, it is proved that this ordering approach is beneficial to improve the space utilization of packing result.


Choice and interest have long been linked to motivation for learning to read and write; however, designing instruction with authentic premises for young children that harness these motivators can prove challenging. In this teaching tip, we describe one kindergarten classroom's experience engaging in Genius Hour, in which children were supported to identify topics about which they were passionate, research those topics, and share their learning with an authentic audience of peers and family members.


Objective: To study the effect of the minimally invasive percutaneous nephrolithotomy(MPCNL) in management of complicated upper ureteric calculi,comparing with transurethral ureteroscope lithotripsy(URL) and extracorporeal shock wave lithotripsy(ESWL).Method: 557 cases of patients of upper urinary tract calculi,collected from Jul.2006 to Jul.2011.Male 318 cases,female 239 cases;from the age 18 to 74,the average age was 38.45±8.63 years.Result: There were significantly difference on the operating time among the three groups(P=0.000),and the MPCNL group had the longest operating time(66.45±12.23 min),while the operating time group of URL group(28.45±8.96 min) and ESWL group(30.80±7.80 min) were shorter,and there were no significantly difference between the URL and ESWL group(P=0.086).The success rate of MPCNL was 97.79%,the stone clearance rate was 97.10%;The success of URL was 85.95%,the stone clearance rate was 82.35%;The success rate of ESWL was 83.72%,the stone clearance rate was 50.00%.The value of hemoglobin decrease in MPCNL group was significantly higher than the other two groups(P=0.000,P=0.000),and there were no significantly difference betweenthe URL and ESWL group(P=0.318).Conclusion: High stone-free rate can be obtained with minimally invasive percutaneous nephrolithotomy for complicated upper ureteric calculi.The stone-free rate was less effective with transur ethral ureteroscope lithotripsy.ESWL easily accepted by patients for its noninvasive,but for large and complex stone has poor treatment effect,As to skilled urologists in conditioned hospitals,MPCNL can be considered to be first choice for complicated upper ureteric calculi.As to lower and fixed position upper ureteric calculi,URL can be considered;ESWL can be considered to those stones diameter less than 1.5 centimeter or a multiple of small stones.


This is a 21-year experience from the Czech Republic and shows the advantage of a centralized health-care system and a comprehensive registry for congenital heart disease. The nationwide screening programme enabled prenatal detection of 1/3 of any form of congenital heart disease and 80% of those with critical forms. Let's hope we can do as well, especially given the new NHS screening advice to include outflow tract views as well as the four chamber view.

A simple and didactic experiment was developed for image monitoring of the browning of fruit tissues caused by the enzyme polyphenol oxidase. The procedure, easy and inexpensive, is a valuable tool to teach and demonstrate the redox reaction between the enzyme and the natural polyphenols. To obtain the browning percentage for apple, pear and banana, digital photographs were employed, and the images were analyzed by means of Monte Carlo methods and digital analysis programs. The effects of several experimental conditions were studied, such as pH, light, temperature and the presence of oxygen or anti-oxidants. It was observed that each fruit presented a different condition that better minimized the oxidation process. The absence of oxygen and the application of a bissulphite solution were sufficient to keep the quality of all fruits tested.


Background: Hyperglycemia is frequently encountered during hospitalization and is associated with adverse outcomes such as acute myocardial infarction, cerebrovascular disease, infection and nephropathy. Is therefore desirable to develop an updated guidelines in order to guide the inpatient glycemic management. Method: Seventeen physicians and a chemistry with expertise in diabetes and insulin management were invited to participate in the development of the guideline based on criteria such as experience, knowledge and clinical judgment. For the purposes of this review the recommendations were based on clinical evidence levels and the limits used were clinical trials and consensus statements developed in adult population that at some time during their hospital stay showed hyperglycemia. results: The expert participants discussed the topics included in this guideline according to their evidence and recommendations levels. Eventually, all the decisions taken were unified in a final document. Conclusions: A glucose range of 140 to 180 mg/dL is recommended. For noncritically ill patients more stringent targets may be appropriate and a scheduled subcutaneous administration of insulin with basal and correctional components is the preferred strategy. Intravenous insulin infusion is the preferred method for maintaining glycemic control in critically ill patients.


Qian Zhongshu put forward Sublimity as the ideal of literary translation in Lin Shu's Translations,which is a significantly transitional translation theory in history.This paper aims at exploring the origin of Sublimity,interpreting Sublimity through analyzing Qian's masterpiece-Lin Shu's Translations-in his own words,and clarifying its modernity and traditional limitations.


Cosmological observations have reached a new era of precision, and reveal many interesting and puzzling features of the Universe. I will briefly review two of the most exciting mysteries: the nature of the dark components of the Universe, and the origin of the asymmetry between matter and anti-matter. I will argue that our best hope of unraveling these questions will need to combine information from the heavens with measurements in the lab at high energy particle accelerators. The end of run II of the Tevatron, the up-coming Large Hadron Collider and proposed International Linear Collider all have great potential to help us answer these questions in the near future.


Like many areas of business, portfolio management is both an art and a science. It is much more than the selection of securities from a catalog by a financial consultant or the application of a formula to a set of financial data input supplied by a security analyst. It is a dynamic decision-making process, one that is continuous any systematic but also one that requires large amounts of astute managerial judgment about the securities markets and the individual for whom portfolio is managed. The author in this article documents the processes involved in portfolio management and the considerations which are of paramount importance in constructing an individual's portfolio.


Multilayer pressure vessel is designed to work under high pressure condition. In this paper, optimization of thickness of each layer in multilayer vessel is carried out by Genetic Algorithm and then stress distribution is analyzed under optimum shrink-fit condition. The fatigue life is calculated for shrink-fit multilayer vessel. Thickness of each vessel is considered as design variable and objective function is maximum hoop stress through-out the thickness at the given working pressure. Multilayer vessel is assumed to be constructed by insertion of different vessels with zero interference and zero clearance such that interface pressure at the mating surfaces is equal to the pressure generated at the same surface due to interference fit. The mathematical model is derived from basic governing equation of thick cylinder. The appropriate boundary conditions are applied to each successive layer. Effect of number of shells on the maximum value of hoop stress is analyzed. Apart from this, effect of overall thickness of pressure vessel on the effectiveness of multi-layering is brought into focus. Stress distribution and fatigue life for the obtained thickness of each vessel from Genetic Algorithm is nearer to that obtained from Lagrange's multiplier method.


Interaction between long piles and the adjacent soil has a spatial and temporal nature. This phenomenon is based on a set of non-linear and rheological properties of soils. Distribution of lateral forces between the surface and the pile toe is heavily dependent on the above properties. The process of formation of the stress-strain state around the pile can demonstrate decaying, constant or progressive velocity depending on the rheological processes in the soil that may be accompanied by hardening and softening processes at one and the same time. These processes may be caused by destruction and restoration of ties between clay soil particles, soil compaction and de-compaction. Predominance of the process of hardening leads to damping, while predominance of the process of softening causes progressive destruction. Description of this multi-component process depends on the rheological model of the soil.


What do we see when we look at data? This recurrent question when confronted to Big Data, is largely answered by two different disciplinary visions dominating the debate during the last years, concluding that data are raw and Big Data is a hubris. While disciplines still treat just a part of them, we experience a wider and wider spreading of Big Data. The notion of "monuments of cyberspace" discussed here helps understand their peculiar nature and delimit related issues of method, of wealth and of experience.


Background: Vaccine programmes' success lies in the acceptability and understanding of vaccine concerns among diverse population groups. This study investigates the covid-19 vaccination concerns among Nigerian youths.
Methods: We conducted a cross-sectional study of 631 youths (343 females and 270 males) between 15-44 years who were randomly recruited online and offline from the six geo-political regions of Nigeria. The questionnaire was administered between 10 February and 15 March 2021. SPSS (Chi-square and Cramer's V Statistic) was used to determine the association (p<0.05)between covid-19 vaccination concerns and participants' demographic characteristics.
Results: Among the 12 identified covid-19 vaccination concerns, side-effects (p=0.037), not necessary (p=0.007), negative reaction to vaccines (p=0.026) and assumed non-exposure to covid-19 patients (p=0.004),, were statistically associated with gender. For age, efficacy doubt (p=0.023), political/economic construct (p=0.023), family disapproval (p=0.018), and non-exposure to covid-19 patients (p=0.000) were statistically significant. Efficacy doubt (p=0.029) and the vaccine is a hoax (p=0.020) were associated with marital status. Side effect (p=0.182), a mere human experiment (p=0.777), doubt on efficacy (p=0.305), not necessary (p=0.457), political/economic construct (p=0.673), negative reaction to vaccine (p=0.162), and the vaccine may not be affordable (p=0.506) were not associated with the occupation. For the level of education, side effects (p=0.140), a mere human experiment (p=0.580), efficacy doubt (p=0.243), and negative reaction to the vaccine (p=0.386).
Conclusion: Amongst youths in developing nations, especially in institutions of learning, health promotion and vaccine advocacy strategies should be intensified. The strategies should incorporate reinstating trust in vaccine efficacy and education and target youths and their family health decision-makers.


In addition to diet quality and quantity, the timing of eating in relation to the circadian rhythm may impact weight status and overall health. Experimental studies suggest that a shorter eating window and extended overnight fast may promote metabolic health and weight loss. Additionally, eating early in alignment with the circadian peak in metabolism may be protective, while eating close to the biological night may promote weight gain. This study examined cross-sectional associations of temporal eating patterns with weight status.

 This study used the Eating & Health Module of the 2006–08 and 2014–16 American Time Use Survey (ATUS), a nationally-representative sample of US adults with a 24hr time use diary (4am – 4am). Respondents ages 18–64 years with a body mass index (BMI) 18.5–50.0 kg/m2 were included. Sleep and primary/secondary eating activities were used to define three temporal eating patterns: duration between (a) end of sleep and first eating activity (morning fast); (b) first and last eating activity (eating window); and (c) last eating activity and beginning of sleep (evening fast). Multinomial logistic regression models, accounting for ATUS survey design, were used to examine associations between each temporal eating pattern and BMI (normal weight, overweight, obese), controlling for age, sex, education, employment, household size, race/ethnicity, total sleep time, weekend, season, and year.

 A total of 38,717 respondents were included. For each hour increase in morning fast, the odds of being normal weight (vs. obese) was 0.95 (95% CI: 0.94–0.97). For each one hour increase in eating window, the odds of normal weight (vs. obese) was 1.05 (95% CI: 1.04 – 1.06), and for each hour increase in evening fast, the odds of normal weight (vs. obese) was 0.96 (95% CI: 0.95 – 0.98) (all P < 0.0001). Similar trends were seen for overweight (vs. obese) (all P < 0.05).

 Though findings for morning fast are consistent with hypotheses, findings for eating window and evening fast are not. Limitations include a single observation day, which may not reflect usual eating patterns and does not consider dynamic weight trajectories, potential influence of bias and misclassification error, and lack of information on diet quality and quantity, which should be considered in future studies.

A 17-ns nonaddress-multiplexed 4-Mb dynamic RAM (DRAM) fabricated with a pure CMOS process is described. The speed limitations of the conventional DRAM sensing technique are discussed, and the advantages of using the direct bit-line sensing technique are explained. A direct bit-line sensing technique with a two-stage amplifier is described. One readout amplifier is composed of a two-stage current-mirror amplifier and a selected readout amplifier is activated by a column decoder output before the selected word line rises. The amplifier then detects a small bit-line signal appearing on a bit-line pair immediately after the word-line rise. This two-stage amplification scheme is essential to improving access time, especially in the case of a CMOS process. The high sensitivity of the readout amplifier is discussed, and the electrical features and characteristics of the fabricated DRAM are reported. >


In Tim Blake Nelson's film Leaves of grass (2009), Bill Kincaid (Edward Norton), a successful professor of Classics at Brown University is lured back to his native Oklahoma when he receives word that his identical twin brother Brady (also Edward Norton) has been murdered. Although he has deliberately distanced himself from his 'eccentric' family for over a decade, Bill dutifully flies home, only to find his 'dead' twin very much alive and planning to use Bill as his alibi for a murder he and his sidekick Bolger (Tim Blake Nelson) intend to commit. While Bill has been diligently crafting his academic career, Brady has instead channelled his genius into growing marijuana hydroponically — part of the reason for the film's title. Brady is in a double bind, having borrowed a substantial sum of money from a Tulsa drug-lord called Pug Rothbaum (Richard Dreyfuss), and being at the same time under considerable pressure to quit the drug business, as his girlfriend is pregnant. This article explores the numerous allusions to ancient Greek and Latin literature, philosophy and culture that the film's director Tim Blake Nelson, who himself majored in Classics at Brown, has confessed to putting into almost every scene. A major focus of this 'tonally varied' film is its exploration of the interface between the two main forms of drama derived from Ancient Greece — tragedy and comedy.


An efficient method for the synthesis of trisubstituted vinyl sulfones is reported. Using the [Ir(COD)Cl](2)/phosphoramidite ligand (L1)/DBU, trisubstituted vinyl sulfones could be synthesized from allyl sulfinates in high yields as exclusively E isomers.


Water-sensitive urban design (WSUD) is a concept that is gaining support as a means to manage urban water systems in an integrated way through the better positioning of the topic of water in urban planning and design processes. Water-sensitive urban design is emerging in the UK and this paper sets the scene and identifies the opportunities and constraints from a UK perspective. Recent developments in integrated water management, ecosystem services and multifunctional land use provide new opportunities for 'getting more for less'. These can range from seeing all forms of water as a resource, exploiting opportunities to contribute to the green and blue infrastructure agendas, resilience to climate and other changes. This paper draws on international experience as to how water-sensitive urban design can deliver opportunities; mitigate the urban development challenges; implement and support institutional, regulatory and practical opportunities and demonstrate the benefits of taking a water-sensitive urban design approach in the UK. The key requirements for delivery are highlighted and a proposed vision for water-sensitive urban design in the UK outlined. © ICE Publishing: All rights reserved.

British policy towards Albanians, at this time, was inspired by the writings of Miss Edith Durham, Margaret Hasluck and other figures who had lived in Albania during the regime of Ahmet Zogu. These were fueled sympathy for albanians, concluded that albania's political fate was determined more by North highlanders, who with their organization had more opportunities to act organized at war. Thus the key to organizing a resistance against Italy in Albania, by british policy, thought to be found in the north, planning activities driven here from Yugoslavia. This policy proved unsuccessful, because not valued the role of Kosovo and Albanian nationalism, as a crucial weight factor in promoting war against the italians and in establishing fair relations between Albania and Yugoslavia, to correct the injustices of the past. Trying to issue as worthless the mountainous terrain factor in the development of guerrilla warfare in Albania, linked this with "more backward political development of the albanians",  was unfounded, prejudicial and an unrealistic look. As a consequence of introducing the game of interests greek-yugoslav and prejudices of the most senior officials of the Foreign Office, efforts to promote fighting irregular as through agents M.I (R) as well as by S.I.S through section D, this service, proved unsuccessful. The failure of british attempts to act in Northern Albania was associated with the british mentality in the perception of Albania and the Albanian issue. By british author Reginald Hibbert noted that, "In the early years of the war was underestimated Albanian nationalism and its significance in relation to its neighbors." Great Britain was not worried about the invasion of albanian lands from Greece after seeing Albania from a new angle of interest, in view of the connections with Greece. Key words:  Albania, Great Britain, Resistence, "Albania question", Revolt in northern Albania.


The maracujazeiro -yellow (Passiflo edulis f. Flavicarpa), is grown throughout the Brazilian territory due to soil and climatic conditions favorable for its cultivation. The objective of this study was to investigate the effect of different levels of manure on vegetative growth and fruit quality of yellow passion fruit. The study was conducted in a commercial orchard Fazenda Sao Jose , located in the municipality of Curral de Cima, PB region of coastal tablelands , the coordinates 06 ° 43 ' 01 " S and 35 ° 16' 08 " W , 130 m altitude. The experimental area is classified as Alfissol . The experimental design used was a randomized complete block design with five treatments and four replications, the experimental plot consisted of 5 plants, with the central 3 plants per plot.

Were evaluated at 60 days after transplanting stem diameter of the plants, the secondary branch diameter, number of tertiary branches, length of internodes. After harvesting the fruits were evaluated: fruit weight, fruit diameter, fruit length, thickness of the rind and pulp yield. The stem diameter , in general , exhibited tendency to increase with increasing levels of cattle manure , the greater diameter of the secondary branch was found in the dosage 40L/cova . The organic fertilization showed significant difference for the variable diameter of the secondary branch. Biometric parameters were not favored by the addition of manure. However the addition of manure favors the improvement of Chemical, physical and biological soil, which justifies the application parameters. Lied heavier fruits in the higher levels of manure. It has been found that the greater the thickness of the shell is lower pulp yield.


Abstract The pseudo-first order kinetics of the reaction of cyclopentanol with phenylisocyanate, catalyzed by dibutyltin di(2-ethylhexanoate) (DBTDEH), was studied by means of UV and IR spectrophotometry. Reaction orders with respect to catalyst and to monomeric alcohol [1] were considered in toluene (Tol), di(nbutyl)ether (DBE) and acetonitrile (ACN). The results, which were interpreted with the aid of rate equations previously derived [2-4] on the basis of a reaction scheme involving an alkoxytin(IV) intermediate, indicate that pre-reaction complexes of solvent-dependent composition are formed in the rate determining step of both catalyzed and uncatalyzed mechanisms [5],


Background. Hyperacute and delayed vascular rejection due to natural antibodies (NAb) present major obstacles in pig-to-primate xenotransplantation. Although "supraphysiologic" expression of human complement regulatory proteins (CRPs) can prevent hyperacute rejection in discordant xenogenic recipients, their physiologic role in the homologous setting is undefined. We have evaluated the effect of the absence of decay-accelerating factor (DAF) on cardiac allograft rejection in the presence of different levels of antidonor antibodies (Ab). Methods. DAF1-deficient (DAF KO; B6129F2 H-2b) mice were used as heart graft donors to α1,3-galactosyltransferase deficient (GalT KO; B6, H-2b) recipients. Heterotopic heart grafting was performed with or without presensitization. Graft survival, histology, and anti-αGal Ab levels were monitored. Results. DAF knockout (KO) but not wild-type (WT) grafts showed hyperacute or acute humoral rejection in nonsensitized GalT KO mice with low levels of anti-αGal IgM NAb. However, humoral rejection of both DAF KO and DAF WT donor grafts occurred in presensitized GalT KO recipients. Conclusions. The expression of DAF prevents hyperacute rejection in mice with low titers of anti-αGal antibody. These studies demonstrate the physiologic role of DAF in preventing humoral rejection in the presence of low levels of NAb and have implications for transplantation of discordant vascularized xenografts.


According to modern concepts, the reverse magnetization of rocks is a result of polarity reversals of the terrestrial magnetic field. However, rocks sometimes become magnetized antiparallel to an applied field during laboratory experimentation. This phenomenon is called self-reversal of magnetization. Self-reversal is also observed when magnetizing synthesized ferrimagnets. This poses the challenge of determining the true nature of the reverse magnetization of rocks. Discussed in this review devoted to investigations into self-reversal of rock magnetization, with emphasis on the physical mechanisms of self-reversal, are both the experimental and theoretical studies of the authors, including results obtained in terms of the model they developed based on the Néel N type self-reversal mechanism. A comparison of computer simulations with experimental results is also presented.


Marc Bullock describes an intense six-week period that he spent as a surgeon attached to Medecins Sans Frontieres in the Democratic Republic of Congo. The working environment and the exotic cases he encountered, partly a reflection on the violence that dominates the region, are bound to have had a profound personal and professional impact. I would imagine that this report will inspire some trainees to seek a similar experience.


The effect of enrichment with hydrolysate of casein on proteolysis by Lactococcus lactis subsp. cremoris SK11 cells in a sodium caseinate solution under cheese-like conditions was studied. Spectrophotometric o-phtaldialdehyde (OPA) assay showed a significantly higher production of free amino groups in samples enriched with hydrolysate. Lysozyme treated sonicated cells and resting cells had similar effect on proteolysis. Samples with no cells added had as-expected significantly less proteolysis. Data from RP-HPLC analysis of the ethanol (70%)-soluble fraction and multivariate statistical analysis of the chromatograms supported findings from OPA assay measurements. Formation of pH 4.6-insoluble protein fragments and peptides, as assessed by urea-PAGE, was not influenced by the addition of bacterial cells or enrichment with hydrolysate. Bioactive peptides that inhibited angiotensin-I-converting enzyme were present in the ethanol (70%)-soluble fraction from samples enriched with hydrolysate, but could not be detected from samples without hydrolysate added regardless of incubation with Lactococcus cells.


In open-pit excavators there exists a discrepancy between their engineering designs and underuse of performance potential due to complexity of excavation and such intensity of carrying out working procedures which borders on physical limits of an operator. The excavating procedure is shown to involve joint functioning of main actuating mechanisms of an open-pit excavator for its thrusting and lifting operations and formation of a leverage transmission mechanism connecting those with a bucket. In that case, it was established, the excavation process is characterized by a 'conversion' of the main mechanisms since their operation parameters are formed according to kinematic properties of the leverage and energy-force parameters realized on the bucket. Dependencies were derived to calculate kinematic transfer functions of the leverage, which correlate the velocity of excavation and those of working motions (speeds of thrusting and lifting). The algorithm of calculating the velocities of working motions could be used to develop a digital system to control the motors of the main mechanisms.
