A regional gravity field product, comprising vertical deflections and gravity anomalies, of the Gulf of Guinea (15°W to 5°E, 4°S to 4°N) has been developed from sea surface heights (SSH) of five altimetry missions. Though the remove-restore technique was adopted, the deflections of the vertical were computed directly from the SSH without the influence of a global geopotential model. The north-component of vertical deflections was more accurate than the east-component by almost three times. Analysis of results showed each satellite can contribute almost equally in resolving the north-component. This is attributable to the nearly northern inclinations of the various satellites. However, Cryosat-2, Jason-1/GM, and SARAL/AltiKa contributed the most in resolving the east-component. We attribute this to the superior spatial resolution of Cryosat-2, the lower inclination of Jason-1/GM, and the high range accuracy of the Ka-band of SARAL/AltiKa. Weights of 0.687 and 0.313 were, respectively, assigned to the north and east components in order to minimize their non-uniform accuracy effect on the resultant gravity anomaly model. Histogram of computed gravity anomalies compared well with those from renowned models: DTU13, SIOv28, and EGM2008. It averagely deviates from the reference models by −0.33 mGal. Further assessment was done by comparing it with a quadratically adjusted shipborne free-air gravity anomalies. After some data cleaning, observations in shallow waters, as well as some ship tracks were still unreliable. By excluding the observations in shallow waters, the derived gravity field model compares well in ocean depths deeper than 2,000 m.

We have measured the Raman spectra of ${\mathrm{NiPS}}_{3}$ for pressures up to 27 GPa at 120 K and room temperature using various lines from an argon ion laser. ${\mathrm{NiPS}}_{3}$ is an $S=1,$ insulating, two-dimensional antiferromagnet which shows an anomalously broad two-magnon excitation. At high pressures, we observe a strong dependence of the intensity, line shape, and frequency of the magnetic spectrum as a function of laser wavelength, reflecting pressure tuning of electronic transitions. ${\mathrm{NiPS}}_{3}$ is the only material exhibiting resonant two-magnon scattering other than the parent compounds of the cuprate superconductors.


An electrostatic force microscope was used to write and image localized dots of charge in a double barrier CeO2/Si/CeO2/Si(111) structure. By applying a relatively large tip voltage and reducing the tip to sample separation to 3–5 nm, charge dots 60–200 nm full width at half maximum of both positive and negative charge have been written. The total stored charge is found to be Q = ±(20–200)e per charge dot. These dots of charge are shown to be stable over periods of time greater than 24 h, with an initial charge decay time constant of tau ~ 9.5 h followed by a period of much slower decay with tau > 24 h. The dependence of dot size and total stored charge on various writing parameters such as tip writing bias, tip to sample separation, and write time is examined.


Higher education has recently been identified as a sector of concern by the UK National Cyber Security Centre (NCSC). In 2021, the NCSC reported that universities and higher education institutions (HEI) had been exponentially targeted by cyber-criminals. Existing challenges were amplified or highlighted over the course of the global pandemic when universities struggled to continue to function through hybrid and remote teaching provision that relied heavily on their digital estate and services. Despite the value of the sector and the vulnerabilities within it, higher education has received relatively little attention from the cybersecurity research community. Over 2 years, we carried out numerous interventions and engagements with the UK higher education sector. Through interviews with cybersecurity practitioners working in the sector as well as roundtables, and questionnaires, we conducted a qualitative and quantitative analysis of threat intelligence sharing, which we use as a proxy for measuring and analysing collaboration. In a unique approach to studying collaboration in cybersecurity, we utilized social network analysis. This paper presents the study and our findings about the state of cybersecurity in UK universities. It also presents some recommendations for future steps that we argue will be necessary to equip the higher education sector to continue to support UK national interests going forward. Key findings include the positive inclination of those working in university cybersecurity to collaborate as well as the factors that impede that collaboration. These include management and insurance constraints, concerns about individual and institutional reputational damage, a lack of trusted relationships, and the lack of effective mechanisms or channels for sectoral collaboration. In terms of the network itself, we found that it is highly fragmented with a very small number of the possible connections active, none of the organizations we might expect to facilitate collaboration in the network are playing a significant role, and some universities are currently acting as key information bridges. For these reasons, any changes that might be led by sectoral bodies such as Jisc, UCISA or government bodies such as NCSC, would need to go through these information brokers.

ABSTRACT
The purpose of this study was to determine the interactions and main effects of NAA and BAP hormones on the growth of Ciplukan (Physalis angulata L.). The design used in this study is a complete random design (CRD) which consists of two factors. The first factor is N (NAA) which consists of 4 levels, namely: without treatment, 0.1, 1, and 10 mg / l while the second factor is B (BAP) consisting of 4 levels, namely: without treatment, 0.1, 1 and 10 mg / l. The parameters observed were the percentage of hypocotyl explants forming callus, the age of callus appearing, the number of shoots, and the percentage of hypocotyl explants forming roots. The observational data is then statistically analyzed, if the F count is greater than the F table then proceed with the BNJ test at the 5% level. The results showed that the interaction of NAA and BAP gave a significant effect on the age of callus with the best treatment was the administration of 0.1 mg / l NAA and mg / l BAP 1 (N1B2). The main effect of NAA was significantly on the age of callus with the best treatment of 1 mg / l NAA (N2). The main effect of BAP was significantly on the age of callus with the best treatment 1 mg / l BAP (B2) and the percentage of hypocotyl explants forming roots with the best treatment without BAP administration (B0).

OBJECTIVES
This study aimed to investigate the molecular mechanism of the Jk(a-b-) phenotype in a Chinese transfusion patient.

BACKGROUND
Many different mutation types relating to Jk(a-b-) phenotype have been reported. However, the splice-site mutation is relatively rare and the related functional verification is lacking.

MATERIALS AND METHODS
In this study, the blood sample was collected from a transfusion patient with the Jk(a-b-) phenotype. Serotyping was performed using routine serological methods. The exons sequences and coding regions of the JK gene were amplified using polymerase chain reaction and directly sequenced. To perform a minigene splicing assay, the intronic mutation sequences were cloned into a pSPL3 splice reporting vector. The splicing reporter minigene assay was performed in HEK 293T cells.

RESULTS
The Jk(a-b-) phenotype of the blood sample was identified through serological testing. Sequencing results revealed that the sample had a novel homozygous splice-site mutation JK*02N (NM_015865.7: c.663+3A>C). Further analysis, including cDNA sequencing and minigene splicing assay, confirmed that the novel splice-site mutation resulted in exon skipping. Interestingly, different numbers of exons being skipped were obtained by the two methods.

CONCLUSION
This study revealed a novel homozygous splicing-site mutation associated with the Jk(a-b-) phenotype in Chinese population. Our results emphasise the importance of the in vitro functional method minigene splicing assay, while also acknowledging its potential limitations when compared to cDNA sequencing.


399 Background: Activation of the PI3K/Akt signaling pathway by PIK3CA mutations has been associated with increased risk for local recurrence (LR) in rectal cancer patients (pts). We hypothesized that loss of expression of PTEN, a tumor suppressor gene and negative regulator of the PI3K/Akt pathway, may also be associated with increased rates of LR in colon cancer.

METHODS
We studied 156 pts with stage II-III colon cancer resected from 1/1990 to 12/2002, including pathology review, PTEN immunohistochemistry, microsatellite instability (MSI) status, 18q loss of heterozygosity (LOH) status and clinical follow-up. PTEN expression with a CLIA-compliant protocol (DAKO antibody) was determined in a tissue microarray with four cores from each tumor and with non-neoplastic mucosa. PTEN loss was defined as complete absence of expression in malignant epithelium with preserved expression of adjoining non-neoplastic tissue serving as a positive control. LR was defined as anastomotic or pericolic peritoneal disease.

RESULTS
83 M and 73 F pts with median age of 63 were included, with median follow-up of 7.6 yrs. PTEN loss was identified in 26 (16.7%) pts. There were no significant differences in age, sex, T stage, N stage, tumor differentiation, tumor site, lymphovascular invasion (LVI), mucinous component, MSI status or 18q LOH between the PTEN-lost and PTEN-intact groups. The overall survival, relapse-free survival, and distant metastases rate were similar. However, PTEN loss was associated with higher rates of LR (15.4% vs. 4.6%, p = 0.041), and the time to LR was shorter for pts with PTEN loss in their tumor than in PTEN-intact pts (HR 3.3, p = 0.049 by log-rank). LR was associated with LVI, R-sided tumor, 18qLOH, and PTEN loss in univariate analysis. In a multivariate analysis, PTEN loss was associated with a 10.6 fold increased risk of LR (95% CI: 1.7-64.8, p = 0.011).

CONCLUSIONS
PTEN loss is associated with a higher rate of and shorter time to LR after resection of colon cancer. This result is consistent with a prior report on the role of PI3K pathway in LR of rectal cancer and suggests that PTEN alteration is a prognostic indicator and that the PI3K/Akt pathway is a potential therapeutic target for these pts. No significant financial relationships to disclose.

Background: The human microbiome is a community of microorganisms that live in symbiosis with humans. This relationship between humans and the microbiome affects the physiology of health and disease, but not many studies have evaluated the condition of the digestive microbiome in neurology critical condition patients and its changes. This study aims to describe the microbiome characteristics of neurological patients in the intensive care unit.
Methods: We conducted a systematic literature review of the relationship between the microbiome and neurology patients admitted to the intensive care unit by searching MEDLINE/PubMed, the Cochrane Database for Systematic Reviews, and Google Scholar for articles in English published through 13 June 2022.
Results: There is a change in the normal flora pattern in neurological patients who are treated in the intensive care unit. The decrease in the number of colonies occurred in commensal flora bacteria and an increase in pathogenic bacteria such as Enterobacteriaceae.
Discussion: The overgrowth of opportunistic pathogens suggests dysbiosis in patients with neurocritical conditions. This is thought to be correlated with the gut-brain axis relationship. This dysbiosis evaluation can be used to provide targeted microbiome therapy and to assess the risk of clinical deterioration and death in neurologic patients in intensive care.
Conclusion: This study reported a significant difference between the composition of the gut microbiota in neurology patients in intensive care and the healthy population. The magnitude of this dysbiosis increases during hospitalization in the intensive care unit and has an impact on patient outcomes. Intestinal microbiota analysis is expected to provide an overview of targeted microbial therapy and predict future patient outcomes.

Keywords: Neurocritical patients, intensive care, microbiome


This paper presents the effects of aluminium substitution on sample composition, density and magnetic properties of yttrium iron garnet, Y3Fe5O12 (YIG). Mill scales, in a form of flakes was obtained from the steel industry in Malaysia. The mill scales was purified to produce high purity hematite, Fe2O3. The mill scales derived Fe2O3 were used as raw material to prepare the aluminum substituted yttrium iron garnet Y3Fe(5-x) Al(x) O12 (Al-YIG) with variation compositional x = 0.0, 0.5, 1.0, 1.5 and 2.0 using mechanical alloying technique. X-ray fluorescence (XRF) was used to investigate the percentage compositions of the raw mill scales. The magnetic hysteresis of sample were investigate by using B-H tracer (MATS). Density of the Al-YIG bulk samples was found to decrease with increasing xAl2O3 content. The saturation magnetization Ms also shows a decrease with increase xAl2O3 content. The maximum saturation magnetization Ms and coercivity Hc was found at 310 G and 14.98 Oe, respectively. With increase xAl2O3 to 2.0%, the Ms and Hc were reduced to 29.35 G and 3.15 Oe, respectively.


Edwards and Yuen (May 1990, pp. 454458) report that their case study "suggests that occupational therapy through home intervention and the incorporation of neurodevelopmental treatment and vestibular and tactile stimulation techniques [has] successfully decreased the decline in the development of a child with Down syndrome" (p. 457). Generalization from their single-subject pretest-posttest design should be done with caution, however, for the following reasons. First, the observed increase in the subject's mental developmental quotient might have been due, at least partly, to a statistical artifact, regression to the mean (Kidder & Judd, 1986). The authors determined two scores for their subject her mental and motor developmental quotients. The score that changed upward, the mental one, was initially lower and thus was more likely to have been affected by regression. The preintervention value may have been unusuaJly low because of consistent bad luck on the various chance factors that influence a score, such as distractions during testing. The increase in the value upon retesting may have resulted from a change to more average luck. Second, the subject's motor developmental quotient decreased by 7 percentage points, as the bottom half of Table 1 (p. 455) shows. Despite interventions intended to promote motor function, its rate of development declined. Third, the subject was much lower functioning than those in the studies of Down syndrome that the authors cited (e.g., Dicks-Mireaux, 1972; Hanson, 1981). What is true of such an atypical patient may not be true of other patients. Fourth, the research was poorly structured in that it included a number of factors that could have influenced the findings. The authors used one frame of reference (neurodevelopmental treatment) and pieces of another (sensory integration). The treatment took place in two settings and was implemented by avariery of professionals (direct treatment) and also by a parent (indirect treatment). Edwards and Yuen judiciously acknowledged that maturation was yet another factor that may have had an effect. Therefore, if any change was real, it is not possible to tell which of those factors was responsible. In addition, the authors, quoting Ayres (1972), state that few precautions are necessary when providing excitatory vestibular stimulation for a child with general hypotonia. Pueschel (1988), however, warned that atlantoaxial instability affects about 15% of children with Down syndrome, and if it is present, some vestibular treatment techniques such as somersaults, trampoline exercises, and roughhousing could injure the neck, causing serious neurological problems such as difficulties in walking, muscle weakness, and abnormal reflexes. Although symptomatic atlantoaxial instabilities are observed in only 1% [0 2% of persons with Down syndrome, the damage can be devastating. Susan G. Nesbit, MS, OTR Glen Rock, New Jersey


Micro flapping-wing air vehicles (FWAV) are highly appreciated by scientists and scholars around the world due to their small size, high flexibility, and better manoeuvrability. There are huge potential applications of flapping-wing robots in rescue, survey, and search, as they can enter more dangerous and narrow spaces to accomplish tasks that were previously impossible for people. In this paper, we first analyze the flapping motion of birds by reviewing a large amount of information and literature and identifying the sources of lift and thrust during flight. Then, the double crank and double rocker mechanisms are optimized as the flapping mechanism. Proper flapping-wing size is further determined by analyzing the relative position between the driving mechanism and the flapping mechanism. Moreover, a pitch mechanism consisting of ball hinges is designed to realize the wing's pitching motion for additional thrust. The fuselage and landing gear of the flapping-wing robot are designed for low air resistance and lightweight, and the tail mechanism are designed to have both roll and pitch freedoms, offering excellent manoeuvrability during flight. Simulation results show positive lift force is generated based on the novel pitching design for the small wing. The research in this paper is an important resource for novice researchers to design and study the advanced and complex problems of flapping-wing air vehicles.

An oral load of L‐phenylalanine (150 mg. per kg. body weight) was given to five women three hours before delivery by hysterotomy of their 16–18 week conceptuses. A sixth woman was delivered of a 16‐week conceptus after two hours continuous intravenous infusion of L‐phenylalanine (75 mg. per kg. body weight per hour).


The genesis of the moral leadership concept in educational administration and examples of studies exploring this idea during the 1979‐2003 period are discussed. The author recommends more contextually sensitive descriptive studies with a focus on the social relations among school leaders and others, giving particular attention, in a phenomenological sense, to the meanings, perspectives, and espoused purposes of school leaders' actions, social relationships, and interpersonal orientations.


ABSTRACT The fear of physical and sexual violence within the family context has not received much attention in the literature. Drawing on a national sample of 11,584 respondents from the 2012 German Victimization Survey, this study examined the prevalence of fear of domestic violence (DV) as compared with fear of physical and sexual crimes in general; identified gender-specific prevalence of fear of DV; and determined socio-demographic factors that predicted fear of DV for men and women. The study found both males and females reported similar rates of fear of both physical and sexual assault victimization in the family context. Younger persons and people with migration backgrounds were more likely to express fear of DV than older persons and German respondents without migration backgrounds, respectively. Future research should examine the fear of domestic violence more systematically.

It is not my intention to consider the clinical aspects of infections which affect the new-born infant through the umbilicus. The seriousness of such infections is well recognized. The more severe and fatal forms present clinical and post-mortem evidence which forces itself on the observer. The proof that milder types of infection originating in the umbilicus cause fever, jaundice, loss of weight and gastro-intestinal disturbances in the new-born infant is difficult to bring forward. It has been demonstrated that serious and fatal umbilical infections can exist and give no local ante-mortem evidence of their presence. It would not be unfair to conclude that milder forms could exist and the infant recover without local manifestations of umbilical disease. Such infections occur in isolated cases and in epidemic form in institutions. There may be the moist gangrene with the foul-smelling, putrefying cord, a simple omphalitis with a discharge of varying character, an


Background and aim Despite the great success of primary total hip arthroplasty (THA), the number of revisions has significantly increased over the past years. The objectives of the study were to investigate the main causes that lead to revision of THA, the time interval between primary THA and revision, and the results of the revision surgery. We also assessed whether there was any correlation between the patients' age, BMI, diagnosis for primary THA and the cause of failure. Methods This paper retrospectively analyzed 189 patients with THA revision surgery performed over a six-year period, between 2015 and 2020. Patients' charts were reviewed to collect data on patient's demographics, patient's primary THA and revision procedures, and the time interval between primary THA and revision surgery. Patients were divided into 3 groups according to the time interval THA-revision: group I (<5 years), group II (5–10 years) and group III (>10 years). Results The patients' mean age (82 men/107 women) was 69.59±7.85 years (range 31–92 years). The most frequent revision cause was aseptic loosening (52%), followed by periprosthetic fractures (18%), infection (17%) and persistent hip instability (12%). Patients' age (r=0.43) and BMI (r=−0.4) had low correlation with the time interval between THA and revision. Conclusions The main causes for revision THA within less than five years are infection and instability, while revision for aseptic loosening is performed especially after five years from the primary THA. Osteonecrosis, post-traumatic osteoarthritis and femoral neck fracture are correlated with a higher incidence of revision at less than five years from the primary THA.


Aims: The impact of postoperative complications after surgery for lung cancer is substantial, with the increasing age of patients and the presence of comorbidities. Impairment in exercise capacity is a potential modifiable risk factor for postoperative complications. This study aimed to assess the contribution of preoperative pulmonary rehabilitation (PR) for increasing operability conditions in non-small cell lung cancer (NSCLC) for patients with limited pulmonary functions and postoperative results.
Methods: The patients with NSCLC who had preoperative pulmonary rehabilitation and underwent surgical resection in our clinics between 2010-2019 were evaluated retrospectively. The patients enrolled in a comprehensive, multidisciplinary, supervised outpatient 10-day duration PR program preoperatively, consisting of bronchial hygiene, breathing control, energy conservation techniques, exercise training (endurance and strength), psychological support, and nutritional support. Exercise capacity and VO2 peak were evaluated by using an incremental shuttle walk test (ISWT).
Results: Eighteen patients who underwent surgery due to NSCLC and had a pre-operative pulmonary rehabilitation program were evaluated. All the cases were male; the mean age was 66.2 (53-77) years. The squamous cell/adenocarcinoma ratio was 2.6 (13:5), and the mean tumor size was 4.6 (8-18) cm. The postoperative hospital stay was 12.7 (4-42) days, and they were followed up for an average of 30.2 (2-83) months.
Conclusion: Complete surgical resection is the most effective curative treatment for lung cancer. However, many patients with lung cancer also have severe COPD, increasing their risk of postoperative complications and their likelihood of being considered "inoperable." Preoperative pulmonary rehabilitation (PR) has been proposed as an intervention for risk modification and to decrease surgical morbidity and mortality. The results of our study also revealed the importance of preoperative pulmonary rehabilitation in centers where lung cancer surgery was performed.


The thermal stability of poly(3-hydroxybutyrate) (PHB) in an oxidation environment was investigated in bulk at temperatures ranging from 100 °C to 140 °C. The process carried out in pure oxygen resulted in PHB backbone degradation with resulting non-volatile products typical for regular PHB thermal degradation while thermal treatment of PHB in an oxygen/ozone mixture resulted in increased rate of polymer backbone scission. The non-volatile degradation product contained macromolecules with several types of terminal groups but also a part of the 3-hydroxybutyrate repeating units was transformed into 3-malic acid units. NMR and multi-stage MS characterization revealed the random distribution of 3-malic acid units in the oligomeric products as well as the content of the malic acid units being dependent on oxidation conditions.

Due to the ever-increasing number of security breaches, practitioners are motivated to produce more secure software. In the United States, the White House Office released a memorandum on Executive Order (EO) 14028 that mandates organizations provide self-attestation of the use of secure software development practices. The OpenSSF Scorecard project allows practitioners to measure the use of software security practices automatically. However, little research has been done to determine whether the use of security practices improves package security, particularly which security practices have the biggest impact on security outcomes. The goal of this study is to assist practitioners and researchers in making informed decisions on which security practices to adopt through the development of models between software security practice scores and security vulnerability counts.To that end, we developed five supervised machine learning models for npm and PyPI packages using the OpenSSF Scorecard security practices scores and aggregate security scores as predictors and the number of externally-reported vulnerabilities as a target variable. Our models found that four security practices (Maintained, Code Review, Branch Protection, and Security Policy) were the most important practices influencing vulnerability count. However, we had low R2 (ranging from 9% to 12%) when we tested the models to predict vulnerability counts. Additionally, we observed that the number of reported vulnerabilities increased rather than reduced as the aggregate security score of the packages increased. Both findings indicate that additional factors may influence the package vulnerability count. Other factors, such as the scarcity of vulnerability data, time to implicate security practices vs. time to detect vulnerabilities, and the need for more adequate scripts to detect security practices, may impede the data-driven studies to indicate that a practice can aid in the reduction of externally-reported vulnerabilities. We suggest that vulnerability count and security score data be refined such that these measures may be used to provide actionable guidance on security practices.


The socialization of the web has resulted in immense information resources that can be remixed by skilled users into new and novel web applications. While these resources are available, there are few who are able, or are even motivated, to create these applications. Continuing our past work, we use survey methods to explore the factors that motivate end-users to learn about and explore remix tools. Our initial results show that users' may involve many social factors in their decision-making. We conclude with lessons learned and outline ongoing research.


Phenolic compounds largely contribute to browning in plant-derived food products (1). Oxidation reactions can be enzimaticaly catalyzed by polyphenol oxidases or peroxidases, or can be carried out in an spontaneous way by autoxidation, if the enzymes are inactivated or removed during the food process.


where subscript "+" indicates the positive part of the expression. We can see that the objective function (A.1.1) for linear nonnegative garrote estimator is a special case of ours (5). To see this, consider (5) without penalty on α. Thus λ0 = 0 and kernel matrix K = ∑ ξjxjx T j . Then the least squares kernel machine solution is related to the OLS solution by choosing the initial α̃ = y. Yuan (2007) applied the nonnegative garrote component selection method to functional ANOVA models. Similarly, we obtain the least squares kernel machine solution as the initial estimate using Representer Theorem:

Management fraud has become a topic of increasing interest to the public accounting profession. Prior research indicates that management fraud is seldom experienced by audiGtors. As a result, it is doubtful that auditors have a well-developed cognitive model for making fraud risk assessments as part of the audit planning process. Early research studies attempted to identify factors that could be linked to the occurrence of management fraud, while more recent work has attempted to build models to predict the presence of management fraud. In this paper, we report on a study that uses a powerful generalized qualitative-response model, EGB2, to model and predict management fraud based on a set of data developed by an international public accounting firm. The EGB2 specification includes the probit and logit models and others as special cases. Moreover, EGB2 easily accommodates asymmetric costs of type I and type II errors. This is important for public accounting firms since failure to predict fraud when it is present a type II error is usually very costly to the firm in terms of litigation. The results demonstrate good predictive capability for both symmetric and asymmetric cost assumptions.


Context. The Perseus arm, the nearest main arm from the Sun, has been studied by multiwavelength observations and numerical simulations. It has been revealed that the Perseus arm has an effect on gas kinematics known as the streaming motion (i.e., systematic peculiar motion), while direct comparisons between the observations and the simulations have been limited due to insufficient spatial/velocity resolutions. Aims. We aim to model the peculiar motion, and to derive physical parameters of the Perseus arm. Using the parameters, we discuss the role of the main arm in the Milky Way. Methods. We directly compare VLBI astrometry results for the Perseus arm, including accurate 3D position and velocity information, with the analytic gas dynamics model proposed by Pi ñolFerrer et al. (2012). Results. We succeeded to explain the VLBI astrometry results with seven model parameters. The model showed an offset between a dense gas region and the bottom of the spiral potential model. Conclusion. Astrometry results can be used to judge previous theoretical works explaining the nature of the spiral arm (e.g., the density-wave theory, the recurrent transient spiral, etc.). The offset predicted from our model can be confirmed by stellar astrometry (e.g., Gaia astrometry). A combination of gas and stellar astrometry results will drastically change our understanding of the spiral arm in the near future.


The Radiological Assessment System for Consequence Analysis, Version 2.1 (RASCAL 2.1) has been developed for use during a response to radiological emergencies. The model estimates doses for comparison with U.S. Environmental Protection Agency (EPA) Protective Action Guides (PAGs) and thresholds for acute health effects. RASCAL was designed to be used by U.S. Nuclear Regulatory Commission (NRC) personnel who report to the site of a nuclear accident to conduct an independent evaluation of dose and consequence projections and personnel who conduct training and drills on emergency responses. It allows consideration of the dominant aspects of the source term, transport, dose, and consequences. RASCAL consists of three computational tools: ST-DOSE, FM-DOSE, and DECAY. ST-DOSE computes source term, atmospheric transport, and dose to man from accidental airborne releases of radionuclides. The source-term calculations are appropriate for accidents at U.S. power reactors. FM-DOSE computes doses from environmental concentrations of radionuclides in the air and on the ground. DECAY computes radiological decay and daughter in-growth. RASCAL 2.1 is a DOS application that can be run under Windows 3.1 and 95. RASCAL has been the starting point for other accident consequence models, notably INTERRAS, an international version of RASCAL, and HASCAL, an expansion of RASCAL that will model radiological, biological, and chemical accidents.


In certain areas of the State of Sao Paulo, Brazil, where transmission of tripanosomiasis by Triatoma infestans has been interrupted for at least six years, ah investigation of domestic enzootic situations has been carried out. A low incidence (0.3%) of infected dogs was found and their infection associated to the existence of Panstrongylus megistus and Didelphis marsupials populations with synanthropic tendency. The use of this survey focusing on domestic animals, mainly dogs, is suggested as a valuable measure in epidemiological surveillance for the early detection of the reproduction of the tripanosomiasis domiciliary cycle.


By integrating cascaded arrayed-waveguide gratings with array switches on silicon platform, we design and fabricate an on-chip multi-functional photonic signal processor. 640-Gbit/s throughput, granularity-flexible programmable optical filtering and reconfigurable optical add/drop multiplexing are demonstrated experimentally.


Camille Paglia is at it again: trend iconoclasm. In a recent email interview with Jonathan Last of The Weekly Standard, the libertarian ("pro-sex", "Amazonian") feminist describes herself as transgender, but goes on to criticise the current campaign for transgender rights.


Using a standardized dataset, this paper compares the differences in income mobility among four countries-Canada, the United States, Great Britain and Germany-during the 1990s and early 2000s. The results suggest that, in general, there exist diverse levels of income mobility across the four countries. Although the precise magnitudes of the differences are sensitive to the measurement method used, incomes in Britain are by far the most mobile. Our findings also reveal country-specific driving forces that underlie income mobility. The stabilizing effects of government transfers are most pronounced in Canada. In Germany, it is the progressive tax system that offsets earnings variations and results in smaller changes in longitudinal incomes. Moreover, we also discover that demographic factors provided only limited explanation of differences in income mobility. Copyright 2009 The Author.

SEA 1180 is the project to replace four RAN classes, totalling 26 small vessels in service at present, with a single class of around 20 Offshore Combatant Vessels (OCVs). This would require a major shipbuilding program which could be beyond the capabilities of any one Australian shipyard.


We have developed Geocomposite used as both reinforsing and drainage material, which is composed by three layers (nonwoven-woven-nonwoven). For this geocomposite, we have done wide-width tensile test and long term creep test, and estimated the mechanical property. Judging from the test results, we confirmed that this geocomposite has advantageous property for reinforcing material compared by non-woven Geotextile,and we considered the long term mechanical property (creep, relaxation) in soil structure. 概要 不織布と織布の3層 構造からなり、補強 ・排水材として使用できるジオテキスタイル複合製品を開発 した。 こ の複合製品に対して、広幅引張試験および長期クリープ試験を実施 し、その強度特性について評価 を行なった。 試験結果より、この複合製品が不織布に比べて補強材としては優れた特性を有することが確認できた。 さらには土構造物内での長期強度特性(ク リープ ・リラクゼイション)に ついて考察した。


Acceleration of environment degradation and climate change poses serious threats to both natural and agricultural ecosystems. In fact, the number of endangered plant species at the global level has increased yearly in the last decades, due to anthropic interventions that sum up to the climate change. Samples of natural plant populations, particularly of wild crop relatives, are ex situ conserved in germplasm banks, which have become active in the provision of genetic resources to breeders. The aim of this article is to generate discussion on the adequacy of (a) current protocols for sampling and ex situ conservation of the natural genetic diversity and (b) the actual species paradigm in plants, due to their consequences for this and future generations.


The combined occurrence of two congenital anomalies, each of which has been already described in a number of cases, seemed to render a publication of our case worth while. I n a previous paper (I) it was pointed out that the lanugo is normally shed shortly before birth, and that the casting of the primary hair is followed by the secondary coat of hair. Congenital baldness may be the result of a disturbance in the earliest development of the hair (3-4 fetal month), or in the development of the secondary coat of hair ( 2 ) . Associations have been found of alopecia universalis congenita with dental defects and defects of the nails. I n cases of so-called ,major ectodermal defect)), moreover, the sweat and sebaceous glands are lacking (3).


This paper investigates into how Constant Based Server(CBS) algorithm with EDF can be used to increase the performance of soft real time applications on multiprocessor systems. To achieve this, the paper improves on CBS and EDF-WM(Earliest deadline first with windows constraint migration) algorithms by proposing and implementing FCBS(Flexible CBS) and EDF-WMR(with reservation) algorithm. EDF-WM algorithm schedule tasks in a task set using the normal EDF algorithm and it assigns task i to a CPU that has enough free capacity to run the task, if such CPU is not found, EDF-WM splits the task i relative deadline and its execution cost based on the number of CPUs in the system and assigns each part to different CPUs. It also allows the divided task to migrate between the different CPUs. CBS algorithm reserves CPU bandwidth for arriving sporadic task by specifying a server budget and a period P. Flexible CBS is proposed as an improvement to CBS by reclaiming unused reserved bandwidth and adding it to the reserved bandwidth of tasks that are running late. To improve the EDF WMR algorithms, the flexible CBS is combined with EDF-WM algorithm. Instead of running the task set using the relative deadline, a certain amount of CPU bandwidth is reserved for the task and then scheduled on the CPU based on either allocating and available CPU splitting the server budget among the CPU. Unused server budgets is also reclaimed and allocated to tasks that are running late. The paper also discusses memory management in real time systems. To improve real time application performance and unnecessary blocking time, memory pages used should not be swapped out to disk. As discussed in the paper, most real time applications reserve all the memory pages needed to run the application at the beginning. These reserved memory pages are not swapped out to disk. However, memory reservation techniques end up over reserving the memory and therefore wasting memory. To improve on this memory reservation technique, PrivateShared-Anonymous Paging (PSAP) algorithm is proposed and implemented. This algorithm reserves a limited amount of private memory needed by the first few jobs of the task. As the task run more memory is provisioned from a larger pool. This allows dynamic use of memory at run time. Memory pages that has not been used for a while is reclaimed and reallocated to task that needs it. To benchmark these improvements, a video application was used. Video application exhibit characteristics of Soft real time system where hard real time guarantees are not needed. The Quality of Service (QoS) of the video application is used as a measure of the improved performance of the system.


The research work investigated the effect of macroeconomic variables on agricultural output in Nigeria. The study used annual data spanning from the period 1995 to 2020. The agricultural output growth represented the explained variable while money supply, commercial bank loan on agriculture, exchange rate, interest rate, recurrent government expenditure on agriculture and inflation rate represented the explanatory variables which served as the selected macroeconomic variables under study. The stationary of the variables were checked using the Augmented Dickey-Fuller test. The long run relationship was tested using the Johansen Co-integration technique. The OLS analysis was computed which shows that the model is statistically significance, judging with the p-value of the F-statistic. The analysis also presented that money supply, exchange rate and inflation have a positive relationship with agricultural output within the given period of study while commercial bank loan on agriculture, interest rate and recurrent government expenditure on agriculture have a negative link with the explained variable. Based on the findings, the researchers recommended among others things, that a favorable interest rate should be placed for farmers to easily access the loans of the financial institutions, which will ensure increase in the productivity of the sector.


Specimens of the cephalocarid Hutchinsoniella macracantha, which were resin-embedded and sectioned for light microscopy, revealed degenerated compound eyes anterior to the labrum. The presence of compound eyes in the cephalocarids adds support to the hypothesis that cephalocarids are an early derivative of an urcrustaceanlike organism that has changed little since Paleozoic times. The Cephalocarida are generally considered to occupy a central position in the evolution of the Crustacea. In studies of external (Sanders, 1957, 1963) and internal morphology (Hessler, 1964), the cephalocarid was found to have both a high degree of serial homogeneity and a very generalized nature. The primitive nature of the heart and ventral nerve cord (Hessler, 1969) as well as gradual anamorphic development with numerous instars (Sanders, 1963) lend support to the viewpoint that the Cephalocarida stand near to protocrustacean stock. But how close is the Cephalocarida to the base of the crustacean evolutionary scheme? Hessler and Newman (1975), after tabulating the "primitive" features of crustaceans, synthesize an ancestral crustacean or "urcrustacean." In many respects (serial homogeneity, limb structure, etc.) cephalocarids closely resemble the Hessler-Newman urcrustacean. However, as Hessler and Newman (1975) point out, there are two major morphological structures lacking in the cephalocarid to make it almost identical to the hypothesized urcrustacean: compound eyes and abdominal limbs. If these structures or remnants of these structures are discovered in the cephalocarids, considerable support will be added to the hypothesis that the cephalocarids are an early offshoot from an urcrustaceanlike organism that has changed little since Paleozoic times. If indeed the lack of compound eyes and abdominal limbs was the result of a gradual evolutionary loss, perhaps remnants may still remain of these structures. Observations of the muscular system (Hessler, 1964) showed no remnants of abdominal limbs. However, details of the nervous sytem have not yet been reported. An analysis of the nervous system would require extremely well preserved and embedded material. Any person who has attempted to dehydrate, embed and section cephalocarids will remark on the difficulty in obtaining good material of these crustaceans. Paraffin embedding is marginally suitable because of penetration problems and, more important, paraffin lacks sufficient matrix to support delicate tissues. Resin embedding does not have these problems and by this method very thin sections can be taken for light microscopy. I was successful in obtaining excellent resin embeddings of adults of the cephalocarid Hutchinsoniella macracantha Sanders. In thin sections for light microscopy, I found structures resembling compound eyes.


The utility model relates to the technical field of paper making equipment, and particularly provides a cambered surface roller in a paper making machine. The cross section of the cambered surface roller is circular. The cambered surface roller comprises installing parts at the two ends and a roller body part in the middle. The diameter of the cross sections of the two sides, close to the installing parts, of the roller body part is larger than the diameter of the cross section of the middle section of the roller body part. The installing parts and the roller body part are connected into a whole and formed by cutting stainless steel bars. The cambered surface roller is simple in structure and low in cost, the cambered surface roller can be machined and formed through simple mechanical cutting, the functions of a traditional cambered surface roller can be achieved, and paper is prevented from generating folds.


Modern cardiac pacemakers and defibrillators function as permanently implanted cardiac monitors, detecting atrial and ventricular arrhythmias. Although the principal purpose of collecting this information is to manage the patient's cardiac rhythm, these data can also be used to detect and study clinically inapparent arrhythmias and their consequences. In this issue of the Journal, Healey and coworkers1 report the results of a prospective study involving patients in whom a pacemaker or defibrillator had recently been implanted (Asymptomatic Atrial Fibrillation and Stroke Evaluation in Pacemaker Patients and the Atrial Fibrillation Reduction Atrial Pacing Trial [ASSERT]1,2; ClinicalTrials.gov number, NCT00256152).

The austenitic Shape Memory Alloy (SMA) can be loaded up to a large strain without any plastic deformation and behaves superelastically (pseudelastically) above its characteristic transition temperature. When loaded, the superelastic SMA undergoes a stress-induced martensitic transformation that will result in a large recoverable strain up to 8%. On unloading, the superelastic SMA experiences a large hysteresis loop that makes the alloy an useful candidate for strain energy absorption. By taking advantage of this effect, SMA is used in various fields. The SMA can be used to improve the impact damage tolerance of composite materials and to induce the relaxation of stress distribution. This investigation deals with the transient thermoelastic problem for a superelastic SMA strip under the heat exchange. In order to simplify the SMA model, a linearization of one dimensional constitutive equations is made. The piecewise linear stress-strain relation is separated into two parts : before and after the stress-induced martensitic phase transformation. Another assumption is the identical SMA stress-strain relation in tension and in compression. Results for the temperature and stresses distributions are obtained numerically. We discuss about the variation of the martensitic phase and the thermal stress relaxation.

Purpose: A system to measure the visibility of agricultural tractor operators was designed and evaluated according to ISO standards, and a blind area diagram around the tested tractor was created based on the manual method recommended by the National Institute for Occupational Safety and Health (NIOSH). Methods: A visibility measurement system was designed and evaluated based on the ISO 5006 and ISO 5721-1 standards. T wo bulbs used to simulate the operator's eyes were mounted on a bar with a supporting frame. A wooden frame was used to determine the seat index point position. The 12-m visibility test circle was divided into six sectors of vision, and the test tractor was placed at the center of the circle. Artificial light was supplied in the darkened environment, and shadow or masking effects were measured manually around the 12-m circle. Results: When the bulbs were placed at the operator's eye level, front visibility was good; no masking was found in the "A" vision sector, but larger masking widths were found in the "B" and "C" vision sectors. Since the masking width exceeded 700 mm, additional tests, such as movement of the light sources to both sides of the operator's eye level, were performed. Less than six masking effects were found in the semi-circle of vision to the front, and more than one masking was found in the "B" and "C" visual fields. The minimum distance between the centers of two masking effects exceeded 2500 mm when measured as a chord on the semi-circle of vision. A blind area diagram was created to define the exact nature of the blind spots and mirror visibility. Conclusions: Visibility evaluation is an effective way to enable proper and safe operation for agricultural tractor operators. Inclusion of this visibility evaluation test in the general testing process might aid tractor manufacturers.


The organic charge-transfer (CT) complexes nanostructures of CuTCNQF4 and AgTCNQF4 (copper/silver tetrafluorotetracyanoquinodimethane) were successfully fabricated by organic solid-phase reaction. The morphologies of CuTCNQF4 and AgTCNQF4 nanostructures can be easily tuned by controlling the reaction temperature. The electron field-emission properties on these nanostructures were investigated. The current density and turn-on field are 4.25 mA/cm2 and 5.48 V/μm for the nanowires of CuTCNQF4, and 1.82 mA/cm2 and 5.21 V/μm for AgTCNQF4, respectively. The results demonstrated that the nanostructures of complexes CuTCNQF4 and AgTCNQF4 were potential candidates for the field-emission cathode.


This paper presents a large-scale real-world application of the minimum-cost flow problem, describes some details of a new implementation of the network simplex algorithm, and reports on computational comparisions. The real-world test sets include minimum-cost flow problems that are based on single-depot vehicle scheduling problems and on a Lagrangean relaxation of multiple-depot vehicle scheduling problems. Some of the problems are extremely large with up to 42,000 nodes and 20,000,000 arcs. The standard test problems are generated with NETGEN and include parts of the DIMACS standard problems. Our network simplex code is compared with \mbox{RELAX-IV}, Cost Scaling 2 version 3.4, and CPLEX's network solver NETOPT.


The pre-clinical phase of type 1 diabetes is characterised by the appearance of several autoantibodies against islet-cell antigens of which the most important recognize islet cells, glutamic acid decarboxylase (GAD), protein-tyrosine phosphatase-2 (IA2) and insulin (IAA). The presence of three or more autoantibodies is associated with a high risk of developing diabetes. The most commonly used assay format for the detection of these autoantibodies is the fluidphase radiobinding assay which cannot identify specific autoantibodies, merely detect their presence. This review describes how the development of disease-specific constructs of GAD and IA-2 has improved the sensitivity and specificity of radiobinding assays but they still cannot distinguish disease-predictive IAA from non-predictive IAA or IAA from insulin antibodies. A new technology, phage display, allows the identification of disease-specific anti-idiotypes of insulin and also facilitates the in vitro production of antibodies with high affinity. This should lead to the development of a high affinity reagent against a disease-specific anti-idiotope of insulin which could then be used in a radiobinding assay, greatly improving the predictive value of single islet-cell autoantibodies.


Management of insect pests of stored wheat is complex and involves many interacting factors, such as grain temperature and moisture, insecticide degradation, aeration, and fumigation. Determining whether or not insects will become a problem in stored wheat is primarily a problem of predicting population increase under future environmental conditions. We have recently developed an expert system, Stored Grain Advisor (SGA), that assists the grain managers in making pest management decisions. Stored Grain Advisor helps the manager to identify insects or other problems, predicts the likelihood of insect infestation, and selects the most appropriate prophylactic or remedial actions. Sophisticated computer models allow the expert system to predict future insect population growth, as well as the degradation of insecticides, and the effects of fumigating or aerating the wheat in relation to storage temperature and moisture. SGA was developed on Apple Macintosh computers using a frame-based shell in conjunction with a C language compiler. The shell has a graphical user interface, backward and forward chaining, explanation and help capabilities. This expert system should prove to be a valuable tool for producers, elevator operators, extension specialists and others concerned with grain storage, and should greatly.enhance our ability to store grain safely.


Since the first use of the colon for esophageal reconstruction by Kelling and Vulliet, the colon reconstruction became a reliable surgical option to reconstruct partially or totally the diseased esophagus. Over the time, the efficacy of colon graft has been thoroughly evaluated and definitively attested by competent surgeons. However the selection of colon segment and completion of the esophageal anastomosis constitute the greatest challenge during esophageal reconstruction. Furthermore the selection of an optimal colon graft should be based on the adequacy of blood supply and the length of reconstruction. The viability and function of the graft affect greatly surgical outcome and functional results. Therefore, knowledge of risk factors, diagnosis, management, and prevention of colon graft necrosis is key to understand and to perform successfully an esophageal reconstructive surgery.


When we speak of the role of the city in the structure and functioning of peasant societies we should not think of it the way we would in the case of a tribal society, as something external to the system. Rather the city and peasant are complementary to the extent that while cities may exist and have developed without peasantry, peasants, by and large, have existence only in relation to cities (Redfield 1953: 31). This interrelationship is one the anthropologist should not ignore. In his traditional focus on tribal society he has perhaps oversensitized himself to seeing the small society as an autonomous whole. But, increasingly, anthropologists are working in socio-cultural milieus that are not clearly bounded but are rather part-societies and part-cultures of a larger whole. If we read the archeological record correctly the urban revolution followed the beginning of the village farming community era by about three thousand five hundred years (Braidwood 1958: 1426-1429). At this time some agricultural tribesmen in the Near East began to become peasant members in a larger political grouping. The transformation of societies based on kinship to those organized on the basis of territory meant that in time new societal types, the peasant and the city-dweller, came into existence.

data, medication use, functionality prior to hospitalization and the Charlson index. We included patients admitted to the emergency room and excluded patients who were admitted electively and those from which we did not obtain complete information. Initially, patients were distributed into two groups: one with hospitalization for less than ten days (G < 10) and the other with more than ten days (G ≥ 10). The two groups were compared according to the outcome death. We used χ2 test and the Mann-Whitney U test. RESULTS: We identified 201 patients. In the G < 10 group, we classified 77 patients, 56% women. The average length of stay was 16 days, the average age was 87 years, 46.0% were using up to 4 medications and 47.5% were using over 4 medications. At admission, 37.8% were using psychotropic drugs and 37.3% had delirium, 26.4% progressed to death. Concerning the length of stay, none of the variables showed significant difference. For the outcome death, the variables delirium, Katz scale and the Charlson index were able to identify patients with higher risk. CONCLUSION: The analysed variables did not allow us to identify patients at increased risk of prolonged hospitalization. The presence of Delirium, higher Charlson index values and lower values in the Katz scale showed a positive association with mortality.

GVF Snake model is used widely in computer vision and image segmentation. However, there are problems in convergence processing to boundaries of human body image because of noise. This paper presents a new segmentation algorithm to human body image. First, rough edge is got by multi-scale algorithm of wavelet analysis, and then thinning method based on mathematical morphology is adopted to get edge map as foundation of GVF Snake model. This method solves the problem that the edge based on wavelets analysis is not consecutive. And it improves GVF Snake model's anti-noise ability. Experiments indicate that the new algorithm can improve snake model's ability to segment the complicated image.


Abstract Functionalized latex particles (FLP) are normally applied for diagnosis and therapeutics purposes and, in particular, the interest in colored FLP is rising in areas such as biomedical and research. The synthesis, characterization and application of FLP with a new colored monomer is here considered, in a simple and fast manner, and at low cost. Synthesis variables were controlled to obtain particles of different size, surface charge and color incorporation. Then, particles were proved in protein binding assays; and the development of an immunochromatographic test was successfully performed. Graphical Abstract


In this study, ethanolic extracts obtained from European mistletoe (Viscum album) and European birthwort (Aristolochia clematitis) were investigated for total polyphenols and flavonoid contents, Fe 2+ chelating ability and free radicals scavenging activity. Scavenging activity was studied for 1,1-diphenyl-2-picrylhydrazyl free radical (DPPH . ), superoxide anion, hydroxyl radical, hydrogen peroxide and nitric oxide. The obtained results indicate a higher content in polyphenols and flavonoids in case of birthwort extract comparatively to mistletoe extract. The polyphenols contained by the two alcoholic extracts have the ability to act as hydrogen donors and can chelate Fe 2+ ; hydrogen donating ability using DPPH . assay and Fe 2+ chelating ability were found to be higher for birthwort extract. Also, the two vegetal extracts had a good scavenging activity against superoxide anion, hydroxyl radical and nitric oxide, while for hydrogen peroxide the activity was low. Generally, free radicals scavenging activity was superior in case of birthwort extract comparatively to mistletoe extract.

Based on endogenous growth theory, this paper analyzes the effect on economic growth of national agricultural expenditure, compulsory education, health care and social security in rural area using the 1994 ∼ 2008 time series data. Through Co-integration test of the associated data combined with error correction model and state-space model, it shows: in the short term, agricultural expenditure has a positive economic effect; however, heath care and social security has a negative effect. In the long run, the order of economic growth impact is agricultural expenditure, health care, education, and social security. Therefore, according to economic growth effects, rural public goods supply priority sequence should be agriculture expenditure, heath care, compulsory education and social security.


Fanconi's syndrome. a constitutional hypoplastic anaemia associated with multiple congenital defects, is sufficiently uncommon to warrant reporting. This syndrome was first described by Fanconi in 1927. It has since been recognized in Germany (Genz, 1952), Greece (Cassimos and Zannos, 1952), Switzerland, Holland, France, Denmark, Great Britain and the United States, and has been reviewed by Reinhold, Neumark, Lightwood and Carter (1952). In the Japanese literature, the only case is that reported by Ida in 1952. We are reporting another instance of this syndrome in a Japanese girl, which, so far as we can determine, is the second to be published from Japan. In our case we have studied the alteration of the peroxidase activity of erythrons, and include our findings here.


The study investigates the predicated thematic structures in the English text and its Urdu translation. The first objective is to define the variations in the Urdu translation of English predicated thematic structures. The second objective is to define how the variations in Urdu translation affect the thematic progression. The data has been collected from the English novel Things Fall Apart by Achebe (1958) and its Urdu translation Bikharti Duniya by Ullah (1991). The UAM Corpus Tool has been used to annotate the data and to find predicated thematic structures and their thematic progression.The findings show that the Urdu translation of English predicated themes is ambiguous and misleading. The English predicated themes have been translated as Urdu unmarked and marked ideational themes. Such unmotivated displacement of themes affects thematic progression. There occur some variations in the thematic progression of translated Urdu themes.

Liquefaction occurs in saturated loose sandy soils that experience an increase in pore water pressure due to the propagation of earthquake waves to the ground surface. This phenomenon raises various questions such as how the groundwater level can affect the occurrence of liquefaction events at different earthquake strengths. The purpose of this study was to determine the effect of groundwater level on liquefaction-prone soils at different seismic peak acceleration values and the effect of relative density (Dr) values on liquefaction-prone soils with variations in groundwater level and earthquake acceleration. In this study, a sample of Jono Oge sand soil was used from the occurrence of liquefaction that met the gradation criteria. The soil was separated through the #8 sieve and retained #100. The modeling technique is carried out with several variables such as the ratio of groundwater level (Hw/Hs) of 25%, 50%, 75%, and 90%, relative density (Dr) 30%-40% and 40%-50%, and at different peak accelerations of 0.3g and 0.4g. The modeling test uses a sieve shaker for earthquake vibrations.. The results of the study show that the difference in groundwater level affects the subsidence of liquefied soil where the settlement will be accure greater in the ratio of the groundwater level (Hw/Hs) and the peak acceleration is greater and vice versa, the difference in relative density (Dr) also affects the magnitude of the the settlement where the lower the Dr value for Hw/Hs and the greater the peak acceleration, the greater the settlement will be occure.


Statistical association measures have been widely applied in information retrieval research, usually employing a clustering of documents or terms on the basis of their relationships. Applications of the association measures for term clustering include automatic thesaurus construction and query expansion. This research evaluates the similarity of six association measures by comparing the relationship and behavior they demonstrate in various analyses of a test corpus. Analysis techniques include comparisons of highly ranked term pairs and term clusters, analyses of the correlation among the association measures using Pearson's correlation coefficient and MDS mapping, and an analysis of the impact of a term frequency on the association values by means of z-score. The major findings of the study are as follows: First, the most similar association measures are mutual information and Yule's coefficient of colligation Y, whereas cosine and Jaccard coefficients, as well as χ2 statistic and likelihood ratio, demonstrate quite similar behavior for terms with high frequency. Second, among all the measures, the χ2 statistic is the least affected by the frequency of terms. Third, although cosine and Jaccard coefficients tend to emphasize high frequency terms, mutual information and Yule's Y seem to overestimate rare terms.


In cerebral artery smooth muscle cells, inositol 1,4,5‐trisphophate (IP3) activates a non‐selective cation current (ICat), leading to vasoconstriction. IP3‐induced ICat activation occurs independently of intracellular Ca2+ release and via type 1 IP3 receptor (IP3R1) and canonical transient receptor potential (TRPC) 3 channel activation. However, signaling mechanisms mediating this effect are poorly understood. Caveolae are plasma membrane microdomains that compartmentalize signal transduction molecules, including TRPC channels. Here, we explored the physiological function of caveolae in mediating IP3‐induced ICat activation and vasoconstriction. A synthetic peptide corresponding to the caveolin‐1scaffolding domain (CSD) sequence (amino acids 82–101 of caveolin‐1) attenuated IP3‐induced ICat activation in cerebral artery myocytes. Methyl‐β‐cyclodextrin (MβCD), which disassembles caveolae, inhibited IP3‐induced ICat. In pressurized cerebral arteries, MβCD attenuated vasoconstriction induced by Bt‐IP3, a cell permeable IP3 analog. Cholesterol replenishment reversed the MβCD‐induced decrease in IP3‐induced ICat activation and vasoconstriction. Taken together, data suggest that caveolae are necessary for IP3R‐induced ICat activation and vasoconstriction.

The term 'crossfertilization of metaphors' from discipline to discipline was used by Dr. Rolf Von Eckartsberg (1983) to describe mutually enriching metaphorical projections between autonomous disciplines aimed at helping scientists to form a particular view of reality or develop their own theories. However, this interesting path of studying conceptual mappings has not received sufficient consideration on the part of researchers though there are insightful observations and case studies of the phenomenon in question in the works of many authors. The current article is an attempt to study the mechanisms underlying the formation of a new conceptual domain – economics – through an interaction of knowledge structures between the new and established intellectual disciplines. Metaphor, analogy, and comparison are "mediators" in this interaction and vehicles in the conceptualization of economic reality and in expressing new cognitive content.


Abstract The 2.5th order differential polarographic reduction behavior of malonaldehyde (MLD) was studied. A sensitive measurement method of the determination of MLD for biological samples was given by using differential voltammetry with a static mercury drop electrode at a scanning speed of 80mV/s in a solution of 0.1mol/L NH4Cl. The linear response range of current(e″) against the concentration of MLD was 1.0×10−6 to 1.0×10−3 mol L and the detection limit was 1.0 × 10−7mol/L. The contents of MLD in the sample of cardiac myocytes was determined rapidly and simply by means of the method.


The reconstruction of this artistically and architecturally very important opera house that was completely destroyed by a fire and which was famous throughout the world not least for its excellent acoustical qualities, was a brilliant challenge also for an acoustician. The historical planning requirements ‐ complete reconstruction "as it was; where it was" ‐ the latest findings in room acoustics as well as a huge number of "modern" requirements are to be brought in line. The theatre hall as heart of the Teatro "La Fenice" was reconstructed in its classical horseshoe shape with five tiers in pure wooden construction. Modern standard specifications had to be met for ventilation and air conditioning, the installation of a modern stage machinery as well as an improved safety and fire prevention concept. Furthermore the space allocation plan had to be extended by the integration of new rehearsal rooms and technical equipment rooms. From the point of view of building and room acoustics this was a very complex task ‐ if in addition the cramped conditions of the Teatro "La Fenice" in Venice are taken into consideration. The lecture provides an insight into the building and room acoustical planning, its realization and the achieved acoustical results.


Edwin Rogers Embree: The Julius Rosenwald Fund, Foundation Philanthropy and American Race Relations, by Alfred Perkins. Bloomington: Indiana University Press, 2012, 363 pp., $39.95, hardcover.Bom in Polk County, Nebraska in 1883 and raised by his maternal grandfather in Kentucky, Edwin Rogers Embree's humble upbringing made him an unlikely candidate to become one of the most dynamic and powerful philanthropists of the 20th century. In Edwin Rogers Embree, Alfred Perkins vividly describes the unusual journey Embree embarked upon from his humble beginnings in Berea, Kentucky, to a distinguished undergraduate career at Yale, from there to the second most important officer in the Rockefeller Foundation and culminating in his role as the head of the Julius Rosenwald Foundation. Here, we have a portrait of a man who dedicated an enormous amount of time dedicating himself to the improvement of the field of race relations.During his formative years in Kentucky, young Edwin was exposed to unusually progressive views on race by his grandfather John G. Fee, the anti-slavery founder of Berea College. Despite being raised in a milieu characterized by a hotbed of racial discrimination off-campus, Embree took classes in a racially integrated environment, noting that: "It never occurred to me that it was anything out of the ordinary to study and recite with Negroes. Some of them were brighter than I was. Some of them duller. It all seemed very natural" (p. 96). This unusually progressive setting, combined with the powerful personal influence of his free-thinking grandfather, shaped his own enlightened attitude on the improvement of race relations.Embree carried these views to his studies at Yale, where he graduated in 1906 with a degree in philosophy, exhibiting a special aptitude for the recently established field of sociology. He remained at Yale for a number of years after his graduation, and was eventually hired to run the office of alumni relations. It was at Yale where Embree made a number of significant contacts crucial to his future career as a leader in philanthropy. Indeed, his work at Yale eventually led him to the notice of John D. Rockefeller, who persuaded Embree to accept the post of Secretary of the Rockefeller Foundation.Perkins does an admirable job of weaving together the unique aspects of Embree's work at Rockefeller with specific actions that Embree undertakes to further his overarching goal of using social science methodologies to fund innovative social justice oriented projects. However, it became clear to Embree that the Rockefeller foundation was spiraling into a bastion of "ultraconservatism," as it was neglecting to address the issues of social justice in which interested Embree. This then lead to his acceptance of the position at the Julius Rosenwald foundation, where Embree was able to translate his philanthropic interests into direct benefits, mostly related to increasing opportunities in education on behalf of African Americans. …


Since the inauguration of cryptocurrencies, Bitcoin has been under pressure from competing tokens. As Bitcoin is a public open ledger blockchain coin, it has its weaknesses in privacy and anonymity. In the recent decade numerous coins have been initiated as privacy coins, which try to tackle these weaknesses. This research compares mostly mature privacy coins to Bitcoin, and comparison is made from a price perspective. It seems that Bitcoin is leading privacy coins in price terms, and correlation is typically high and positive. From the earlier crypto market peak of 2017–18, only a very small number of coins are showing positive returns in 2021. It is typical that many privacy coins have lost substantial amounts of their value (ranging 80–90%) or that they do not exist anymore at all. Only Horizen and Monero have shown long-term sustainability in their value; however, their price changes follow that of Bitcoin very closely. The role of privacy coins in the future remains as an open issue.


OBJECTIVE
To analyze the intakes of dietary energy and macronutrients among the elderly aged 65 and above in China in 2015.

METHODS
Data was from the China National Chronic Non-communicable Disease and Nutrition Surveillance of adults in 2015. Stratified multistage cluster sampling method was used. The valid dietary data of 18 161 the elderly aged 65 and above were extracted from 302 surveillance sites in 31 provinces. Consecutive 3-day 24-hour dietary recall method and household cooking oils and condiments weighting method were applied to collect dietary intakes data. The intakes of daily energy and macronutrients were calculated using China Food Composition Tables 2004 and 2009, and the dietary quality were evaluated according to 2013 Chinese Dietary Reference Intakes.

RESULTS
The study showed that the average intake of daily energy was 1595. 5 kcal, the average intake of carbohydrates, proteins and fats were 208. 7 g, 47. 9 g and 63. 6 g, respectively. The proportion of energy from carbohydrates, proteins and fats were 52. 7%, 12. 1% and 35. 4%, respectively. The carbohydrates intake and proportion of energy from carbohydrates among urban elderly were 202. 3 g and 51. 4%, all lower than that in rural(213. 6 g and 53. 7%, P<0. 05). While the proteins intake and proportion of energy from proteins among urban elderly were 50. 8 g and 12. 9%, all higher than rural elderly(45. 6 g and 11. 5%, P<0. 001). The fats intake and proportion of energy from fats among urban elderly were 64. 1 g and 35. 9%, rural elderly were 63. 3 g and 35. 0%, there were no significant differences in fats intake and proportion of energy from fats between urban elderly and rural elderly(P>0. 05). The dietary intake of energy and macronutrients among the oldest old were lowest, especially those in rural areas, were 1394. 4 kcal, 182. 4 g, 40. 1 g and 56. 4 g. In 2015, the rate of energy lower than EER among the elderly was 75. 8%, and the rate of percentage of energy from carbohydrates lower than DRIs was 41. 5%. The rate of proteins lower than recommended nutrient intake was 76. 6%. The rate of percentage of energy from fats higher than dietary reference intakes was 64. 5%.

CONCLUSION
In China, the unreasonable dietary intake among the elderly aged 65 and above is severe, and the oldest old especially those in rural areas have the most serious deficiency in proteins intake.

Thus, the staff training system for the book-trading network, including the publishing cooperative, had some specific features. Compared to the program to train workers of printing production, where the state took part actively, the financing for the training of booksellers and cooperative publishers was totally devoid of state support. This was the fundamental position of the Soviet state, which, despite the New Economic Policy, continued "to look" at the sphere of trade and the associated need to study the book market, as a relic of capitalism. It is undeniable that giving the cooperative the opportunity to organize a training system for the book-trading network to some extent intensified the market relations in the republic, facilitated the study of the specificity of readers' demand as well as stimulated the development of publishing activity in Ukraine. However, the peaceful coexistence of the socialist-organized production of printed matter and the market system of its proliferation lengthy until the end of the 1920s, when, together with the cooperative publishing houses, a training staff system for the book trade was state-controlled.

Flesh tone is a kind of important habitual color and it should be preserved to the best when people reproduce color images.In this paper, a new method is proposed based on the experiment of geometric characteristics of the gamut of flesh tone. By comparing and analyzing the geometric relation of the two gamuts of flesh tone and the printer at every hue,this paper proposes a compression gamut mapping method preserving flesh tone. The basis of this method is the distribution of the two gamuts. The new method adjusts the kernel coefficient continuously according to varying hues so it preserves most of the flesh tone.It is better to process the images containing flesh tone color than those available ones.


Quality of service (QoS) is becoming an attractive feature for high-performance networks and parallel machines because it could allow a more efficient use of resources. Deadline-based algorithms can provide powerful QoS provision. However, the cost associated with keeping ordered lists of packets makes them impractical for high-performance networks. In this paper, we explore how to adapt efficiently the earliest deadline first family of algorithms to the high-speed networks environments. The results show excellent performance using just two virtual channels, FIFO queues, and a cost feasible with today's technology.

Let the literary critics and the horticultural experts argue the merits of Gertrude Stein's well-known "rose is a rose is a rose is a rose." Medical educators, however, and especially those who do research in medical education, should not blandly assume that a "movie is a movie is a movie is a movie" nor that "TV is TV is TV is TV." This false assumption has contaminated much consideration and most research into the value of media in education. Reports of studies fail to indicate whether the samples used are typical of their medium or whether they are superior. On the contrary, there are clues that discrimination, based on thorough knowledge of the media including their potentials and limitations, was lacking. A common example is when students' learning from a motion picture recording of a lecture is compared with their learning from a classroom lecture on the same topic. "No
