The oldest exposed rocks, to the north of intrusive rocks and in Eastern Bajestan, are meta-chert, slate, quartzite, thin-bedded crystalline limestone and meta-argillite. They are exposed, to the north of intrusive rocks and in eastern Bajestan. Since both Sardar Formation (Carboniferous) and Jamal Formation (Permian), close to this association, are not metamorphosed, therefore the regional metamorphism and the rocks must be older than Carboniferous. The sedimentary units are: Sardar Formation (Carboniferous), Jamal Formation (Permian), Sorkh Shale and Shotori Formations (Triassic), K1, K2, K3 (Cretaceous) and lithostratigraph-ically equivalent to Kerman conglomerate (Cretaceous-Paleocene) are exposed in this area. Based on relative age, magmatism in eastern Bajestan and Taherabad started after Late Cretaceous and it has been active and repeated during Tertiary time. At least, three episodes of volcanic activities are recognized in this area. The first stage was mainly volcanic flow with mafic composition and minor intermediate. The second episode was mainly intermediate in composition. The third stage was changed to acid-intermediate in composition. Since the plutonic rocks intruded the volcanic rocks, therefore they may be Oligo-Miocene age. Bajestan intrusive rocks are granite-granodiorite-quartz monzonite. Taherabad intrusive rocks are diorite-quartz diorite- monzonite-latite. Bajestan intrusive rocks with magnetic susceptibility less than 20 ×10-5 SI are reduced type (ilmenite series) and Taherabad with susceptibility more than 100 ×10-5 SI are oxidized type (magnetite series).Based on geochemical analysis including trace elements, REE and (Sr87/Sr86)i = 0.71, Bajestan intrusive rocks formed in continental collision zone and the magma has crustal origin. Taherabad intrusive rocks were formed in subduction zone and magma originated from oceanic crust. Taherabad intrusive rock has exploration potential for Cu-Au.


The present study illustrates the purification and kinetic characterization of an alkaline protease from UV-90 mutant strain of Bacillus subtilis. The enzyme was purified using four steps purification Ammonium Sulfate Precipitation, Dialysis, Ion Exchange Chromatography and Gel Filtration Chromatography. The protease produced under optimum conditions (pH 8 temperature 50°C, inoculums, 2.5 mL and fermentation time 72 hours with enzyme activity 95.89 U/mL) was 2.47-fold purified through four steps purification protocol and the purified enzyme was characterized by studying the effect of varying pH, temperature and substrate concentrations. Kinetic Studies showed that Km and Vmax values for purified protease (UV-90) were 0.03064 μM and 69.76 U/mL, respectively as compared to 0.02669 μM and 56.73 U/mL of native protease respectively. These characteristics render its potential use in biotechnological and industrial sectors.


Women at all levels of South African society began articulating their interests in the 1950s, with the Women's Charter preceding the Freedom Charter by a year. Since 1994 South Africa has taken bold steps to advance the interests of women and made great strides in the quest for gender equality and women's empowerment. However, persistent disparities remain in South Africa between women and men with regard to senior positions in the higher education sector. Drawing on a number of dialogues and discussions, this paper seeks to analyse the reasons behind gender inequality in education and reveal whether patriarchal values and stereotypes related to women in certain sectors of South African society are a factor. This paper will contend that despite legislation protecting women, both subtle and overt forms of discrimination still exist in the sphere of higher education. The paper also seeks to analyse challenges still being faced as well as offer possible solutions to the gender inequality that continues to prevail in the education sector.

Ion thrusters can be used in a variety of primary and auxiliary space-propulsion applications. A thruster produces a charge-exchange plasma which can interact with various systems on the spacecraft. The propagation of the charge-exchange plasma is crucial in determining the interaction of that plasma with the spacecraft. This paper compares experimental measurements with computer model predictions of the propagation of the charge-exchange plasma from a 30 cm mercury ion thruster. The plasma potentials, and ion densities, and directed energies are discussed. Good agreement is found in a region upstream of, and close to, the ion thruster optics. Outside of this region the agreement is reasonable in view of the modeling difficulties.

In this paper an adaptive optimal path planning in combination with nonlinear model predictive control is presented for trajectory tracking of an ultraflat overrunable mobile robot. As a basis for nonlinear control, the dynamical model of this nonholonomic robotic system, that is used particularly for testing purposes of advanced driver assistance systems, is derived. The aim of this work is to apply model predictive control to minimize the lateral distance between a desired path and the current robot position with respect to physical constraints of the robot. In order to smoothly approach to the desired track, in particular at high velocities, a new path is planned at each sampling instant which heads the mobile robot back on a desired path. This new reference trajectory for the model predictive controller is based on B-Splines, whereby the corresponding control vertices are calculated by means of a quadratic program with respect to minimal curvature. Implementation details as well as sufficient simulation results are shown.


Analytical expressions for the heat loss from buried pipes have been known for a long time. In this paper, we derive approximate expressions for the heat loss from partially buried pipes. The approximations for the overall heat loss are accurate to within 10% of the rigorous solution of the heat conduction equation for the soil, and provide a smooth, continuous transition between the unburied and the completely buried case.


The use of a suitable irrigation solution and a correct root system shape effectively contributes to the success of endodontic treatment. Among the irrigating solutions used in Endodontics, sodium hypochlorite has been the most used because of many qualities. However, this substance must have chemical stability of its properties, by maintaining the potential of hydrogen (pH) and chlorine concentrations appropriately. Objective: The aim of this study was to evaluate active chlorine releasing and pH of some sodium hypochlorite solutions used in endodontic clinical practice. Material and methods: The solutions tested in this study were 0.5% Dakin, 1% Milton, 2% Chlorinated Soda, and household bleaches (Brilux®and Qboa®), which were opened at the same period and first used, with the same storage modus but with different manufacturing dates. The pH was measured with a digital device, and the active chlorine content was obtained through iodometric titration. Results:All solutions presented chlorine content not smaller than that informed in the flasks, ranging from 1% to 2.4%; pH was higher in all solutions, between 9 and 13. Conclusion: Based on the method applied and the results obtained, it was possible to conclude that sodium hypochlorite solutions used specifically in Dentistry (Dakin and Milton solutions and Chlorinated Soda), showed on the labels the hypochlorite content. On the other hand, household bleaches (Brilux® and Qboa®) showed the chlorine content. It was not possible to compare pH authenticity, due to lack of description on the label.


Background: Wilson's disease (WD) is a genetic disorder (autosomal recessive) that affects copper metabolism. A favorable prognosis for WD can be achieved with early diagnosis and treatment. It is also strongly advised to conduct a family screening. Objectives: To find the relationship between genotype and phenotype to facilitate the diagnosis of the disease as well as using modern methods in diagnosing WD. Materials and methods: This study included nine WD patients and fifteen healthy participants. Members of patients with WD and healthy members provided whole blood. Blood DNA was extracted, and Exon 14 was amplified using specific primers using polymerase chain reaction (PCR). The results of the PCR products were aligned to the published human genome database using the BLAST tool. Results: Three different variations have been recorded as a result of the experiment. All of the changes point to a deficiency in the ATP7B protein, which has been identified as a cause of WD. Conclusion: The ATP7B gene mutation spectrum in Iraqi patients has been enhanced as a result of our research, and this information could be used to develop gene therapy and clinical/prenatal diagnosis to prevent WD in Iraq.


Objective: To study the mammographic features of breast carcinoma which showed no distinct mass or calcification. Methods: The clinical data, ultrasonographic and momographic features of 26 cases of breast carcer comfirmed by surgery and histopathology but without distinct mass or calcification by mammography were retrospectively analyzed. Results: All 26 patients were palpated to have mass or nodule. Among them, 25 were classfied small or massine mammary gland type. There was no distinct interface between disease foci and mammary glands. In histopathology 24 cases were infiltrative ductal carcinoma and were infiltrative lobular carcinoma of the breast. Conclusion: Breast carcinoma without distinct mass or calcification by mammography but with clinical palpated mass should be carefully study and compared with the other breast.

Weyerhaeuser has put processes in place to involve business units and corporate management in setting the forest products company's RD Pulp, Paper and Packaging; and Wood (Building) Products. Non-core businesses were sold or shut down and new business development was eliminated. The mission of corporate R&D was also refocused to one of helping our core businesses succeed over the long term. With this new mission it became critical to gain the confidence and support of the business units if we were to be successful. Following considerable dialogue with the business leaders, processes were put into place to realign the organization and to involve business units and corporate management in prioritizing the corporate R&D program. This article gives an overview of the processes that were developed to align and prioritize the corporate R&D activities. Vision and Mission At the outset of these changes, new vision and mission statements were crafted for corporate R&D to reflect the refocused direction (see Figure 1.) There are several dimensions to the mission, ranging from technical support to long-range research. A broad range of services is provided to business and operating units, including analytical and testing services, environmental testing and engineering, manufacturing support, and statistical quality control. These technical support activities are paid for entirely by the internal customers and generally receive top priority from the units providing those services. These services constitute approximately 60 percent of the total. Workforce is adjusted up or down over time by the service units to meet the demands of internal customers. The corporate-sponsored research and development program is broken into three components: core research, strategic programs and development projects. Together they constitute about 40 percent of the total budget for corporate R&D. 1. The core research component provides a steady level of support for the key technical competencies we consider necessary for Weyerhaeuser's sustainable competitive advantage. The technical staff is organized to work on ongoing, long-range research and technology assessment programs in four broad technical areas relevant to multiple businesses: materials technology, manufacturing technology, environmental sciences and technology, and biological sciences. 2. In contrast to the steady level of funding for core programs, strategic programs come and go. They are initiated on the basis of our technology intelligence efforts, and typically follow a funding trajectory that starts out modestly with data gathering and assessment, increases substantially as the technology needs are identified and developed, and winds down as specific commercialization opportunities spin off into the development program. …


"Multi-Domain Operations" paradigm has been receiving significant attention both in military and civilian worlds. This novel notion of operating networks of distributed and mostly unmanned autonomous devices in multiple domains - air, land, water, cyber, and space- in coordination to achieve a common objective, will undoubtedly be a key enabler for various applications. To realize this novel paradigm, it is imperative to establish robust communication links to transfer data between devices operating in multiple domains. However, as of today, establishing high data rate, robust, secure, and bi-directional communication links between aerial and underwater assets across the air-water interface is still an open problem. This article introduces the software-defined visible light networking to establish bi-directional wireless links through the air-water interface. We first overview the limitations of the state-of-the-art solutions for communication across air-water mediums and alternative approaches. We then present a software-defined visible light communication (VLC) modem, which is the primary building block of our proposed solution. We also discuss the challenges, limitations, and opportunities of using visible light to communicate over the air-water interface. Last, we present some key concepts and applications that can be enabled by leveraging the proposed visible light networking solution.


Abstract
Collective evidence points to a prominent role of stress in cancer growth and metastasis. Despite these results an etio-pathogenetic role has not been widely accepted. Reasons of controversies are the coexistence in stressed


Over the course of more than three centuries of Romanov rule in Russia, foreign visitors and residents produced a vast corpus of literature conveying their experiences and impressions of the country. Ranging chronologically from 1613 to 1917, this is the most comprehensive bibliography of first-hand accounts of Russia ever to be published. Providing full bibliographical details and concise but informative annotation for each entry, this substantial bibliography will be an invaluable tool for anyone with an interest in contacts between Russia and the West during the centuries of Romanov rule.


A regression analysis-based method was proposed to weaken linear system's coupling degree,and transform the accurate mathematical model-based coupled analysis into establishing an optimal regression equation between the input and output,and to determine the input quantity that significantly influences the output through a significance test of regression equation coefficient.Compared with existing methods,the theory analysis and simulation results show that regression analysis-based method requires no precise mathematical model,and can be applied to the coupling degree analysis of non-square systems boasting of different input and output variables.


Let $\Phi$ be a convex function on $[x_0,+\infty)$ such that$\frac{\Phi(x)}x\to+\infty$, $x\to+\infty$, $f(z)=\sum_{n=0}^\infty a_nz^n$ — a transcendental entire function, let $M(r,f)$ be the maximum modulus of $f$ and let $$\rho_\Phi(f)=\limsup_{r\to +\infty}\frac{\ln\ln M(r,f)}{\ln\Phi(\ln r)},\quad c_{\Phi}=\limsup_{x\to +\infty}\frac{\ln x}{\ln\Phi(x)},\quad d_{\Phi}=\limsup\limits_{x\to +\infty}\frac{\ln\ln\Phi'_+(x)}{\ln\Phi(x)}.$$ It is proved that for every transcendental entire function $f$ the generalized order $\rho_\Phi(f)$ is independent on the arguments of the coefficients $a_n$ (or defined by the sequence $(|a_n|)$) if and only if the inequality $d_{\Phi}\le c_{\Phi}$ holds.


The reaction of isolable dialkylsilylene 1 with benzil gave [1+4] cycloadduct 1,3-dioxa-2-sila-cyclopent-4-ene 2 and unexpected 2,5-dioxa-3-silabicyclo[2.1.0]pentane derivative 3. Compound 3 slowly isomerized to 2. The global reaction route mapping method of the model compounds suggests that three reaction paths from an initial silylene–ketone complex (carbonyl silaylide) to 2. A large ring strain energy of model compound for 3 (3′) (218.9 kJ·mol−1) was estimated by density functional theory calculations.


Objective: To cross validate the diagnostic performance of transabdominal ultrasound and computed tomography for discrimination of benign and malignant masses. Study Design: Comparative Cross sectional study. Place and Duration of Study: The study was conducted at department of Radiology from January 2008 to December 2008. Materials and Methods: The study was conducted in department of radiology from January 2008 to December 2008 .In this study 50 patients with adnexal masses admitted in Gynae MCH ,General Surgery wards of PIMS, scheduled for surgery, were included, using histopathology as a gold standard. Results: TAUS had sensitivity of 78%, specificity 88.8%, Positive predictive value of 85.7% and negative predictive value of 82.7 %. CT scan showed sensitivity of 91%, specificity of 81.4%, positive predictive value of 80.7% and negative predictive value of 91%.

TAUS is as accurate as CT scan in characterization of an ovarian mass.


The pupae of Dahliana geniculata (Olivier) and Da. echinus (Edwards) are described and illustrated completely for the first time. A table lists the range and the mode of the branching of each pupal seta. A short key is given for identification of phytotelmic aedine pupae, i.e. Da. geniculata, Da. echinus and Da. gilcolladoi (Villa, Rodriguez & Llera), Ochlerotatus berlandi (Seguy) and Oc. pulcritarsis (Rondani).


EDITOR, - The Lesson of the week by Roland J Korner and colleagues highlighted the dangers of fluoroquinolones.1 We have also noted that patients with chest infections have been treated with ciprofloxacin in general practice; the slower resolution of their Streptococcus pneumoniae infection required a change of antimicrobial agent, and one patient died.

We understand, however, that ciprofloxacin is not promoted as first line treatment in general practice for community acquired chest infections, but some general practitioners in our area have provided promotional material …

In order to increase the ease of operation of a circuit breaker (2) it is provided that, as an operating device for manual actuation of a switching element (12) of the circuit breaker (2), a touch-sensitive control board (20) is integrated in a housing (16) of the circuit breaker (2).


Cloud computing has recently gained significant attention because of the emergence of new internet-based applications which utilize cloud computing infrastructure in the data centers (DCs). Therefore, Internet traffic and traffic generated within a data center has also increased exponentially. Traditional data center networks, which are based on the electrical switches, are not adequate to handle increasing bandwidth demands of these applications. They are also not power efficient. A new optical switch architecture, based on optical switches, for data centers is presented in this paper. Optical switches are more power efficient and they can support larger bandwidths. The proposed architecture, namely, extended-hybrid optical switch architecture (E-HOSA), relies on software defined network (SDN) networking paradigm. Similar to SDN, E-HOSA has a separate control plane and a data plane. We perform analytical modelling of E-HOSA to evaluate its cost and power consumption. The comparative analysis of E-HOSA is performed with other famous electrical / optical networks for data centers. The results have shown significant improvement in power consumption as compared to other networks on the cost of increased capital expenditures (CAPEX). However, this increased CAPEX is mitigated to some extent due to its increased power efficiency. We also perform scalability analysis of E-HOSA. The analysis shows that E-HOSA is scalable to thousands of servers which is suitable for a very large scale data center.


Abstract A method is described for the study of transport processes in ghosts isolated from rat adipose cells. With this procedure it was possible to follow the time course of potassium uptake, potassium release, and sodium release. The uptake of potassium was stimulated by sodium and was inhibited by ouabain at concentrations down to at least 10-6 m. In the presence of pyruvate (1 mm), potassium uptake showed a more rapid initial increase, and the steady state level was more than doubled. Glucose (5 mm) produced a smaller stimulation of potassium uptake. Cyanide, 2,4-dinitrophenol, or incubation in the cold diminished both potassium uptake and content. Potassium efflux, unlike uptake, was not altered by ouabain or pyruvate; a half-life of 45 min was found. Sodium ion was exchanged but not accumulated by ghosts. Efflux studies showed that sodium was released with a half-life of 10 min. It is concluded that potassium is accumulated by ghosts of fat cells via a sodium-linked, energy-requiring process characteristic of an intact plasma membrane.


Seventy-five patients with below-knee amputations have used a device called a bent knee pylon for immediate and continued ambulation prior to permanent prosthetic fitting. The advantages and disadvantages of the bent knee pylon have been described. In seven patients with knee flexion contractures, range of motion was increased with the use of the bent knee pylon. Immediate postsurgical prosthetic fitting with ambulation one or two days postamputation was first described by Berlemont in the late 1950's (1). The results and advantages of this concept have been described by many authors in the past several years (1-5). At Fitzsimons General Hospital, this concept,has been followed with minor variations. A method of early ambulation utilizing a bent knee pylon deviee-f-the belowknee amputee has been developed and used at this hospital with good results. Most of the patients with amputations treated at the hospital sustained multiple traumatic injuries from fragment wounds. The patients arrive via medical air evacuation from the Republic of Vietnam usually 1 to 6 weeks post-injury, depending on the extent of their other injuries. While in the evacuation chain from the battlefield to the stateside hospital, the patients' stumps are left open to decrease post-injury infection; frequently skin traction is applied to minimize the retraction of skin and soft tissue from the end of the stump.

The COVID-19 pandemic has affected many aspects of people's lives and territories. It has a destabilizing effect on the economy due to both direct and indirect factors. In order to develop an effective policy to combat such emergencies, the problem of studying its consequences seems urgent.To form effective responses to the consequences of the pandemic, adequate scientific tools are needed to assess them. In many of the studies conducted, the impact of the pandemic was assessed without considering the previously existing socio-economic trends in the regions.The purpose of the article is to conduct a retrospective analysis of the consequences of economic instability caused by the COVID-19 pandemic on the socio-economic development of the region on the example of the Sverdlovsk region. The monthly values of twelve main socio-economic indicators from January 2016 to December 2021 were analyzed. The study is based on the use of regression models with dummy variables and seasonal autoregression for forecasting, which allow considering the seasonal dependence of socio-economic indicators.To determine the seasonality of individual indicators, a graphical method, autocorrelation correlograms and spectral analysis were used. When determining the uniformity between the predicted and actual values during the pandemic, the parametric Student's criterion and the nonparametric Wilcoxon criterion were applied, which allowed us to obtain a statistically significant result regardless of the normality of the compared aggregates.The retrospective analysis made it possible to establish a significant heterogeneous impact of the COVID-19 pandemic on most of the analyzed spheres of life in the Sverdlovsk region.


We have used a table-top scale laser to dynamically compress iron at strain rates in excess of 109 s−1. Using an embedded ultrafast interferometer, we have measured corresponding free surface histories with a time resolution of approximately 10 ps. We have analyzed the surface histories using a method that accounts for nonsteady wave propagation and time-dependent material behavior. We show that at these strain rates, the α→ϵ polymorphic transition begins within 100 ps after an initial very large (∼10 GPa) and mostly elastic compression and appears largely complete within a similar time thereafter. The corresponding deviatoric stress before the transition begins can exceed 3 GPa, while the transition stress itself is up to 25 GPa, nearly twice the value measured at low strain rates. We use these results to propose a systematic variation with loading time of the normal-stress/relative-volume curve followed by iron during rapid compression.


Background . After the cessation of longitudinal growth, growth hormone (GH) continues to subserve an important role in the regulation of body metabolism (stimulation of lipolysis and lipid oxidation, protein synthesis, insulin antagonism, and sodium and water retention) to optimise body composition and function. Most patients with hypopituitarism exhibit the syndrome of GH deficiency with a number of abnormal features which can be reversed with recombinant GH replacement therapy. Conclusions . GH-deficient patients have decreased lean body mass and bone mineral content, increased fat mass, reduced muscle strength and exercise performance, dyslipidemia and increased prevalence of other risk factors for atherosclerosis. They exhibit increased cardiovascular morbidity and mortality and impaired quality of life. It has been shown that GH replacement normalises body composition and exercise capacity, reverses early atherosclerotic changes in major arteries, improves cognitive functions and quality of life. As the treatment with recombinant GH is life-long and expensive it should be offered to patients who exhibit most symptoms and have been proven to have severe GH-deficiency.


In order to improve the thermostability of Penicillium expansum lipase(PEL),a mutation P197E was created by site-directed mutagenesis.The mutation is generated by overlap extension PCR using the cDNA of a single site mutant lipase ep8 as the template and two special primers that corresponding to mutation P197E.Recombinant vector pPIC3.5K-ep8-P197E which contain double-mutant genes was constructed and electroporated into Pichia pasteris GS115.The recombinant transformant was selected and grow in the methanol containing media for expressing double-mutant lipase,PEL-ep8-P197E.Thermostability analysis reveals that the residual activity of the double-mutant are 42.13% and 37.3% greater than that of the wild type PEL and PEL-ep8 after incubated at 40°C for 30 min.The Tm of the double-mutant lipase is 41.51°C,2.81°C higher than PEL and 2.25°C higher than PEL-ep8.


The purpose of constructing national parks is to explore a route of harmonious interaction between protection and development.Laojun Mountain National Park in Lijiang city,Yunnan Province is one of the core regions of the world natural heritage in three-river parallel flow area,where extremely rich natural exists and cultural landscape resources.By analyzing local traditional forest culture of minorities and the active influence on ecotourism,this paper points out that the core position of forest culture should be stressed and the development of ecotourism products should be blended into the characteristic of local forest culture.An ecotourism products system with regional characteristics can be established in Laojun Mountain National Park through developing recreation areas,holding activities with local characteristics such as forest culture festival,photography exhibition of mountain flowers,green food fair,and exhibition of the result of protecting wild animals and plants,green summer camps and the education base of biological diversity.


Diurnal time activity and habitat use of wintering and spring-migrating Lesser Snow Geese were studied in the middle Missouri River valley during 1983 and 1984. Geese spent the majority of daylight hours sleeping and loafing. During winter and spring migration, geese spent 17.5% and 24.0% of a 12-h day feeding, respectively. Geese primarily fed in corn stubble fields; they also fed on winter wheat and bromegrass. The availability of waste corn in the middle Missouri River valley presumably influences the winter distribution of Snow Geese.


Objective:To investigate the clinical significance of fascin expression in gastric carcinoma.Methods: The clinic and pathological information of 76 cases of gastric carcinoma were collected.We detected the expression of fascin in the tissues of gastric carcinoma and compared with their own normal gastric tissues with immunohistochemical stain.Results:There was no expression of fascin in normal gastric tissues.Fascin protein was positive in 24 cases among the 76 gastric carcinoma and they correlated with pathological WHO classification,TNM staging,serosal invasion,lymphatic metastasis and distant metastasis.Fascin protein had no correlation with age and gender.Conclusion:The expression of fascin is positive in part cases of gastric carcinoma.It correlates with the local invasion and metastasis of gastric carcinoma.The expression of fascin can help to assess the prognosis of gastric carcinoma.


In this work, we consider the relay selection (RS) method for an Amplify-and-Forward (AnF) relaying system in multi-cell environments. The selection scheme aims to maximize the instantaneous received signal-to-noise and interference ratio (SINR). We propose an idea of combining RS with interference cancellation (IC) at the receiver. Furthermore, we analyze the system outage probability performance with the proposed scheme. We use approximation approach to simplify the derivation of the probability distributed function (PDF) of the received SINR. The system outage probability bound is also given. Simulation results validate our analysis, and show that our scheme greatly improves the system outage probability as well as bit-error-rate (BER) performances.


Seven samples of colombian bentonite clays were characterized by different techniques such as chemical analysis, XRD, CIC, TGA and IR, selecting the purest sample to be used for the polymer-clay nanocomposite preparation. The selected bentonite was organically-modified with an hexadecilamine, and the product was analized by XRD, IR, TGA and DSC to confirm the effectivity of the treatment. The best amount of modifiying agent was stablished to be 33% weight at which both, the highest inter-layer spacing and the appropriate organofilic character to be compatible with the polymer, were achieved. The nanocomposites were prepared by mixing and fusion in an extruder, using recycled PET and varying amounts of natural and modified clay, and were subjected to mechanical testing and physicochemical analyses.


The theoretical correction formulation for the effect of the acceleration distribution of the mass is deduced,and is validated by the finite element method.The prediction deflection of the theoretical correction formulation is estimated.This work will give reliable base for the uncertainty analysis in dynamic force calibrations.


Unmanned Aerial Vehicles (UAVs), or drones, which can be considered as a coverage extender for Internet of Everything (IoE), have drawn high attention recently. The proliferation of drones will raise privacy and security concerns in public. This paper investigates the problem of classification of drones from Radio Frequency (RF) fingerprints at the low Signal-to-Noise Ratio (SNR) regime. We use Convolutional Neural Networks (CNNs) trained with both RF time-series images and the spectrograms of 15 different off-the-shelf drone controller RF signals. When using time-series signal images, the CNN extracts features from the signal transient and envelope. As the SNR decreases, this approach fails dramatically because the information in the transient is lost in the noise, and the envelope is distorted heavily. In contrast to time-series representation of the RF signals, with spectrograms, it is possible to focus only on the desired frequency interval, i.e., 2.4 GHz ISM band, and filter out any other signal component outside of this band. These advantages provide a notable performance improvement over the time-series signals-based methods. To further increase the classification accuracy of the spectrogram-based CNN, we denoise the spectrogram images by truncating them to a limited spectral density interval. Creating a single model using spectrogram images of noisy signals and tuning the CNN model parameters, we achieve a classification accuracy varying from 92% to 100% for an SNR range from -10 dB to 30 dB, which significantly outperforms the existing approaches to our best knowledge.


HTHE PROPERTY TAX is still the chief source of tax revenue for local government and a major source of inequality in taxation. The inequalities persist even though state governments have struggled to equalize the property tax load since the later part of the nineteenth century. Legislatures have created boards of assessment and equalization, tax commissions, and revenue departments and have vested in these state agencies the power to equalize property assessments, to initiate discharge proceedings against incompetent local assessors, and actually to reassess local property in jurisdictions where original assessments have proved unsatisfactory. More recently state supervision has taken on the aspect of technical assistance to local assessors, often in addition to the harsher measures, but, as a practical matter, mainly in lieu of them. In many instances, however, insufficient funds have curtailed state assistance programs. Concurrent with this trend to concentrate in the hands of state tax administrators the power to control and supervise the administration of the local property tax, legislatures have modified the tax itself in an effort to curb its worst abuses. Revenue sources for state and for local governments have been


The dynamic scaling properties of a polycrystalline growth model proposed by Van der Drift are discussed. We present an analytic derivation of the dynamic exponent, describing the growth of monocrystalline surface domains, yielding p=1/2 and 1/4 for two and three dimensions, respectively. For specific, highly nonuniform, initial conditions in the two-dimensional model we find that initially the exponent p is equal to 1, but that after some time, crossover takes place to p=1/2. The results are confirmed by numerical simulations for the two-dimensional case


R stresses have a major impact on the ability to fabricate dimensionally accurate machined components from aluminum wrought mill products. In addition, the ability to implement advanced assembly technologies such as determinant assembly, where parts are indexed to each other rather than to expensive assembly tooling, is compromised when the parts are not dimensionally accurate. An active research project on this subject is underway in which NCNR scientists are collaborating with Alcoa and Boeing. The current status of this project is outlined in this report. In this work, finite element methods (FEM) are being used to predict residual stress profiles and to examine the influence of material processing and machining approaches on part distortion. However, although Alcoa is developing new destructive methods to estimate residual stresses in bulk materials, the neutron diffraction capabilities of the NCNR for characterizing residual stresses is key to validating both the FEM calculations and the measurement technique being developed at Alcoa. Ultimately, the goal is to understand the generation of residual stresses and how to control their effects in manufacturing and to correlate model predictions with actual experimental measurements. This information is critical in achieving optimization of the Residual Stresses and Optimizing Machining Strategies for Aluminum Bars


Ab initio CCSD(T)/CBS(T,Q,5)//B3LYP/6-311++G(3df,2p) calculations have been conducted to map the C3H3O2 potential energy surface. The temperature- and pressure-dependent reaction rate constants have been calculated using the Rice–Ramsperger–Kassel–Marcus Master Equation model. The calculated results indicate that the prevailing reaction channels lead to CH3CO + CO and CH2CO + HCO products. The branching ratios of CH3CO + CO and CH2CO + HCO increase both from 18 to 29% with reducing temperatures in the range of 300–2000 K, whereas CCCHO + H2O (0–10%) and CHCCO + H2O (0–17%) are significant minor products. The desirable products OH and H2O have been found for the first time. The individual rate constant of the C3H3 + O2 → CH2CO + HCO channel, 4.8 × 10–14 exp[(−2.92 kcal·mol–1)/(RT)], is pressure independent; however, the total rate constant, 2.05 × 10–14 T0.33 exp[(−2.8 ± 0.03 kcal·mol–1)/(RT)], of the C3H3 + O2 reaction leading to the bimolecular products strongly depends on pressure. At P = 0.7–5.56 Torr, the calculated rate constants of the reaction agree closely with the laboratory values measured by Slagle and Gutman [Symp. (Int.) Combust.1988, 21, 875−883] with the uncertainty being less than 7.8%. At T < 500 K, the C3H3 + O2 reaction proceeds by simple addition, making an equilibrium of C3H3 + O2 ⇌ C3H3O2. The calculated equilibrium constants, 2.60 × 10–16–8.52 × 10–16 cm3·molecule–1, were found to be in good agreement with the experimental data, being 2.48 × 10–16–8.36 × 10–16 cm3·molecule–1. The title reaction is concluded to play a substantial role in the oxidation of the five-member radicals and the present results corroborate the assertion that molecular oxygen is an efficient oxidizer of the propargyl radical.


EU and national buildings related regulations are moving towards policies that improve indoor thermal comfort, reduce energy consumption and its environmental impact by establishing very ambitious targets in the emissions reduction in the decades to come. In this context, improving energy efficiency through deep energy renovations is a key action line because of its potential to meet long-term climate and energy targets. However, deep renovations need to become more environmentally friendly, more reliable in terms of performance and more attractive to all concerned stakeholders, in addition of enabling the implementation of the Near Zero-Energy Building (nZEB) assumed by the Energy Performance of Building Directive in 2010. This paper highlights the key aspects related to the strategic pillars of deep renovation and explore ongoing related funding schemes to meet Portugal´s carbon neutrality and related sustainability goals.


All the creatures on the earth are related to the process of birth which is a sign of new start along with growth and perception of atma (soul). God has sanctified the female with most precious gift of motherhood. Ayurveda, the system of Indian medicine and science of life deals with the wellbeing of mankind. The event o f pregnancy desires patience and determination for almost a year. Hence every science lay efforts to make the process safe, having a lesser amount of trouble and successful with medicinal and non - medicinal ways to attain healthy mother and healthy baby and that is called as Antenatal or prenatal care. Nutrition is defined as the science of food and its relationship to health. Influence of diet of a pregnant woman on fetal development is well known today. Everything that affects the mother has impact up on t he baby. To minimize the risk of disturbances for the duration of pregnancy, a regime for the pregnant woman to follow called Garbhini Paricharya (Antenatal Care) is advised in Ayurveda and to understand the effect of said antenatal care scientifically, th is study is undertaken with the aim to discuss the role of diet specifically. Ayurvedic classics as well as Modern available literature have been consulted in regard to present paper. Garbhini paricharya (antenatal care) advocated by Ayurveda is to avoid h azardous effects on fetus, to promote normal growth and development of fetus and to conduct normal delivery without any fetal and maternal complications. Dietetic regimen described in Ayurveda is beneficial if followed properly and can be modified as per t he life style of an individual accordingly.


In rats fed a high fat diet (HFD), long-term administration of 3,5-diiodo-L-thyronine (T2), a naturally occurring iodothyronine, was shown to reduce body-weight gain, fat mass, and hepatic lipid accumulation. This work was aimed at investigating the mechanisms of T2 action in the liver of HFD rats. The results show that HFD induces liver lipid peroxidation and stimulates the activity of enzymes involved in hydrogen peroxide (H2O2) metabolism, catalase in particular. Moreover, quantitative RT-PCR revealed HFD-induced upregulation of the transcription factor PPARα, as well as of metallothionein isoforms (MT-1 and MT-2). T2 administration prevented the HDF-induced lipid peroxidation, as well as the increase in H2O2 metabolism, and reduced the upregulation of both PPARα and MT-2. These data demonstrate that in the liver of HFD rats, T2 prevents both lipid accumulation and oxidative stress associated with increased fat metabolism.


The discovery of a new type of a heavy long-lived particle (LLP) would be of fundamental significance due to their existence in many beyond the Standard Model scenarios. LLPs are anticipated in a wide range of physics models which extend the Standard Model, such as Supersymmetry and Universal Extra Dimensions. Since LLPs produced in 7 TeV pp collisions at the CERN LHC can be slow (beta << 1) and penetrating, time-of-flight and anomalous dE/dx energy loss measurements are promising ways to search for LLPs. In some cases these heavy objects may lose all of their energy and come to rest within the densest parts of the detector volume, decaying later, potentially out-of-time with collisions from the LHC. We present searches for LLPs using the ATLAS experiment, describing the techniques used and the results achieved to date.


The utility model discloses a novel reverse water-spraying toothbrush and belongs to the field of tooth brushing. The novel reverse water-spraying toothbrush comprises a brush head with bristles and a handle. The novel reverse water-spraying toothbrush is characterized in that a plumped water guide cavity is formed in the reserved side of the bristles and in the neck portion, close to the brush head, of the handle, a water spraying hole is formed in the handle face of the outer surface of the water guide cavity, after teeth are brushed, the water guide cavity of the toothbrush directly aligns at running water of a faucet, and tap water flows through the water guide cavity and then ejects a blast of water in an oblique-upward mode in the rotating direction of the water spraying hole so that a user can conveniently and directly use clean water to rinse the mouth. The bristles of the toothbrush can be replaced, two protruded round sleeve parts on a base plate of the bristles can be replaced, and two corresponding round sleeve holes are formed in the brush head. The novel reverse water-spraying toothbrush is ingenious in structure, the water guide cavity is formed in the reverse direction of the bristles, also when the user conducts tooth brushing, toothpaste foams can not flow to the water guide cavity backwards, and the novel reverse water-spraying toothbrush is ingenious in design, simple and novel.


Heaviness refers to a sequence of partial sums maintaining a certain lower bound and was recently introduced and studied in [11]. After a review of basic properties to familiarize the reader with the ideas of heaviness, general principles of heaviness in symbolic dynamics are introduced. The classical Morse sequence is used to study a specific example of heaviness in a system with nontrivial rational eigenvalues. To contrast, Sturmian sequences are examined, including a new condition for a sequence to be Sturmian.


ABSTRACT To the Editor.— At Bellevue Hospital I have recently had experience with the problem of trying to orally administer fluids to the occasional pediatric patient (or to any patient, if one were to extend the problem) who will not drink liquids, but who will eat solid foods. This is a real problem not infrequently encountered in pediatric and geriatric practice, especially in patients with organic mental illness. The solution is frequently a simple one and one that has been used for years in various circles of pediatric care. Jello, custard, or other such products, consisting of some carbohydrate and protein in a comparatively vast amount of water, is frequently tolerated well, because it is in a "solid-like" form. For example, a five-year-old girl with congenital rubella, who would only swallow solid foods, was spared intravenous hydration by simply administering Jello along with the solid diet. Thus I would like to


The Ground Level area of an apartment building commonly serves as a Transition space, Service
space, Community field, Identity area and Defensive space. The functions of this area can be
broken into 4 categories: Housing type, Public space, Piloty and Commercial area. Good planning
involves with augmenting characteristics of each category. For Houses at this level, planning to
make use of their closeness to the soil is advised, while in case of Piloty, ccirculation with extemal
environment is a deciding factor. In case of Commercial facilities, though they help to give identity as
an entrance of apartment block, these shops are likely to hamper above-level houses' environment
conditions. Additional measures for safety and terrotority should be considered.


This study provides evidence that a negative association exists between quality number and fibre diameter for fleeces grown in the same flock. The efficiency of classing by quality number, as a means of separating fleeces of different average fibre diameter, varies from flock to flock and may be influenced by such factors as the strain or breed of sheep, the nutritional level, the environment, and the age of sheep.


We propose a new approach for measuring the mass profile of dark matter halos by stacking the lensing magnification of distant background galaxies behind groups and clusters of galaxies. The main advantage of lensing magnification is that, unlike lensing shear, it relies on accurate photometric redshifts only and not on galaxy shapes, thus enabling the study of the dark matter distribution with unresolved source galaxies. We present a feasibility study, using a real population of z ⩾ 2.5 Lyman break galaxies as source galaxies, and where, similar to galaxy–galaxy lensing, foreground lenses are stacked in order to increase the signal-to-noise ratio. We find that there is an interesting new observational window for gravitational lensing as a probe of dark matter halos at high redshift, which does not require a measurement of galaxy shapes.


Based on specimens collected from northern Iran, the subfamily Leylaiyinae is recorded for the first time from Iran and a new species of the genus Leylaiya, L. aquilonia Gharali & Evenhuis, sp. nov. is described and illustrated. A key to species of the genus and their distributions are presented.


In recent years we have witnessed an increasing demand to process queries on large datasets in Non-ordered Discrete Data Spaces (NDDS). In particular, one type of query in an NDDS, called box queries, is used in many emerging applications including error corrections in bioinformatics and network intrusion detection in cybersecurity. Effective indexing methods are necessary for efficiently processing queries on large datasets in disk. However, most existing NDDS indexing methods were not designed for box queries. Several recent indexing methods developed for box queries on a large NDDS dataset in disk are based on the popular data-partitioning approach. Unfortunately, a space-partitioning based indexing scheme, which is more effective for box queries in an NDDS, has not been studied before. In this paper, we propose a novel indexing method based on space-partitioning, called the BINDS-tree, for supporting efficient box queries on a large NDDS dataset in disk. A number of effective strategies such as node split based on minimum span and cross optimal balance, redundancy reduction utilizing a singleton dimension inheritance property, and a space-efficient structure for the split history are incorporated in the constructing algorithm for the BINDS-tree. Experimental results demonstrate that the proposed BINDS-tree significantly improves the box query I/O performance, comparing to that of the state-of-the-art data-partitioning based NDDS indexing method. key words: non-ordered discrete data, multidimensional indexing, spacepartitioning, box query, and algorithm


Using authentic audio-visual material in early language classes has become commonplace, but little prior empirical research has been published regarding why this pedagogical technique is effective for some students, and not others. This study examines the process of engagement and transportation of beginning foreign language learners into an authentic, Spanish language narrative-based music video. A structural equation model is developed that ties various elements such as belief consistency, cognitive difficulty, and affective disposition to the process of narrative engagement. The study then examines how a student's engagement and transportation into the music video's narrative impacts that student's language learning, thematic comprehension, and entertainment – three commonly cited objectives of using authentic audio-visual material. Evidence is provided to indicate that the degree of engagement and transportation into the narrative-based video influences students' language learning, thematic comprehension and entertainment.


The single-terminated DETA was obtainded by the reaction of butyl glycidyl ether(n-BGE) and benzyl glycidyl ether(BGE) with diethylene triamine(DETA).The product was mixed with sulphamate(DETA-SO3Na) and then the mixture reacted with epoxy resin(E-51) to synthesis novel aqueous epoxy curing agent containing multi-imine and sulfonates.The two-component aqueous epoxy coating was prepared by the curing agent and E-51.The structure of the synthesized curing agent was characterized by FT-IR.The effect of DETA-SO3Na amount on the particle size and properties of the cured two-component coating film were studied.The result showed that the optimum formula was as followed:[n(DETA-n-BGE)+n(DETA-BGE)+n(DETA-SO3Na)]∶ n(E-51)=2∶ 1,ω(DETA-SO3Na)=5.6%,n(n-BGE)∶ n(BGE)=3∶ 2.The two-component coating has small particle size(790 nm)and good stability(1.5 h).The pencil hardness,flexibility,impact resistance and water resistance of the cured film was 2 H,1 mm,55 kg/cm and 180 h,respectively.

Lately, interest in phase-change materials has been renewed in order to design a new generation of active optical reconfigurable devices in combination with plasmonic technologies to achieve low consumption and ultrafast characteristics for a wide range of applications spanning from optical switches, photonic memories, logical gates, etc. Within the possible candidate materials, gallium sulphide exhibits desirable properties as a marked change in the optical properties between crystalline and amorphous phases, low losses at visible frequencies, stability in environmental conditions, to name a few. Therefore, an accurate description of its optical response is desirable to predict the behavior subject to external excitations. In this contribution we present the modelling of the dielectric function of crystalline GaS from ab-initio calculations, including excitonic effects to achieve quantitative agreement with experimental results.


The combination of perennials and annuals in a strip cropping system is challenging primarily because the interspecific competitive ability of the perennials towards the annuals seems to be too dominating. Especially at the first harvest (tillering) closest to the adjacent grass-clover strip severe total dry matter production reductions was found ranging from 25%, 5% and 20% in the vetch SC, rye SC and vetch-rye IC, respectively. Rye in particular was suffering from the grass-clover interspecific competition with a SC yield of 700 g DM m-2 (0-25 cm) at maturity as compared to 1025 g DM m-2 when grown > 150 cm away. When grown >150 cm away from the grass-clover strip rye accumulate 8 g soil mineral N m-2,which is in the range of the expected according to organic yield potentials, but only 5 g soil mineral N m-2 when grown 0-25 cm from the adjacent grass-clover. Grass-clover is clearly more competitive towards soil mineral N than adjacent rye plants. The ability of vetch to fix its own N might be an advantage if there is no other limiting growth parameters, like e.g. soil water, indicated by no significant difference between final harvest of vetch SC with 0-25 cm (480 g DM m-2) and >150 cm (550 g DM m-2) distance to grass-clover. The Land Equivalent Ratio (LER = LP+LB) based on aboveground DM production and N accumulation varied between 0.85-1.25 comparing harvests and distance to adjacent grass-clover. At maturity LER values show that available plant growth resources was used 25% more efficiently in intercrops than sole crops when grown with >25 cm and less than 75cm from the adjacent grass-clover strip. Ecosystem services like biomass for energy, functions like leguminous N2-fixation and the capacity of e.g. perennial species to act as carbon sinks should gain more attention when addressing climate change mitigation tools within the framework of organic farming principles and values before these more multipurpose cropping systems like the present strip cropping concept can be fully evaluated. Furthermore, the value of subdividing fields into strips to avoid the buildup of pathogens and pests, depletion of soil nutrients and to improve soil structure and fertility by e.g. alternating deep-rooted and shallow-rooted plants needs further research.


Objective To evaluate the treatment, outcome, and prognostic factors in patients with head and neck sarcomas treated in an academic medical center. Study Design Case series. Setting Academic medical center. Subjects and Methods We performed a retrospective analysis of adult patients (n = 97) with primary head and neck sarcomas treated between 2000 and 2012. We analyzed the treatment, outcome, and potential factors predictive of disease-free survival and disease-specific survival. We also evaluated the outcome and prognostic factors in patients with bone and soft tissue sarcomas. Results The median overall survival was 6.8 years, with 2-year and 5-year overall survival rates of 78% (95% confidence interval [CI], 66%-86%) and 59% (95% CI, 44%-72%), respectively. Univariable analysis revealed that age at diagnosis (>60 years: hazard ratio [HR], 2.7; 95% CI, 1.2-6.2; P = .01), surgical intervention (HR, 8.3; 95% CI, 3.5-19.5; P < .001), and metastatic disease (HR, 4.3; 95% CI, 1.3-13.6; P = .01) were significantly associated with disease-specific survival. Conclusion In this study, patients over the age of 60 years at diagnosis and those with inoperable disease at initial presentation had significantly worse disease-specific survival. Surgical intervention remains the optimal treatment modality for those with resectable disease and was associated with significantly better survival in this heterogeneous series. Further multi-institutional studies are required to better define prognostic factors in individual histological subtypes.


In order to examine the reactivity of cyanoguanidine (CG) with formaldehyde, CG was first hydroxymethylated, then methoxylated, and finally exhaustively hydroxymethylated with a large excess of formaldehyde. 4-Cyanoimino-3-methoxymethylperhydro-1,3,5-oxadiazine was isolated as a major reaction product of 1,3-bis(methoxymethyl)-2-cyanoguanidine with formaldehyde. This product is an adduct of 3 mol of formaldehyde per mole of CG and a six-membered cyclic ether. Minor products were further methoxylated and 3,5-bis(methoxymethyl)-4-methoxymethyl(carbamoylimino)perhydro-1,3,5-oxadiazine was isolated. This is an adduct of 2 mol of formaldehyde to the amidinated product derived from the major product by the hydration of the cyano group. The ring structure of perhydro-1,3,5-oxadiazine was so stable that it could not be decomposed under acidic conditions if the methoxymethyl groups were fully acid-hydrolyzed.


The authors studied the stochastic Logistic model in a polluted environment.Some conditions for stochastic weak average persistence and local extinction of the population were obtained by using the theory of stochastic differential equations.The threshold can be established in some cases.

A 3.2Gb/s clock and data recovery (CDR) circuit for a high-speed serial link without the reference clock is described. The CDR has a phase and frequency detector (PD and FD), which incorporates a half-rate bang-bang type oversampling PD and a half-rate frequency detector that can achieve low-jitter operation and improve pull-in range. The PD of oversamping method finds a phase error by generating four phase up/down signals. The FD also finds a frequency error by generating frequency up/down signals. Therefore these six signals control three charge pump (CP) respectively. It also has a ring oscillator type voltage controlled oscillator (VCO) and three charge pumps. The VCO consists of four fully differential delay cells with rail-to-rail current bias scheme that can increase the VCO tuning range and tuning linearity and each delay cell has a duty-cycle circuit(DCC) as a buffer of the duty-cycle mismatch compensation. The CDR circuit was designed for fabrication using 0.18µm 1P6M CMOS process. The designed circuit consumes 148mW from 1.8V supply voltage according to simulation results.


Economic man"is an abstract man. Adam Smith abstracted it to pave the way for analysis of man's actual economic behaviour and its outcome (market economy) and render a support for the logically strict contruction of theoretical economic system.


The first picture in the photo album that forms part of One Writer's Beginnings shows the young Eudora Welty in a telling moment: the delighted child is clenching her father's pocket watch, dangling its fob before the camera. "Life doesn't hold still," she later comments about her own photographs. "A good snapshot stopped a moment from running away" (84). Like her own art that seeks the revealing gesture in the fleeting scene, the emblematic photo of the one-year-old halts Eudora Welty forever in the paradoxical position of keeping time--of marking its passage and holding it as a possession. One Writer's Beginnings is written precisely at the point of such temporal convergence. It reveals the confluence of past and present as the design of Welty's life and art by making such intersection the structural principle behind her lifestory as an artist. In writing her autobiography at such a junction, Welty turns what seems like a necessity of the genre into a statement of her self. Augustine's description of memory as the "present of things past" (258) defines the dual temporal perspective basic to autobiography. But as if following Ben Franklin's annals of the self-made man, a long tradition in American autobiography has arranged memory into chronology and emphasized the past over the present. One Writer's Beginnings duly acknowledges the custom of organizing a retrospect by hours and years. The pocket watch held by the infant Eudora in the photo keeps the conventional passage of time echoing throughout Welty's memoirs. As a child, she recalls growing up to the sound of a grandfather clock, cuckoo clock, and bedroom clock. As a college student, she felt the tolling of the chapel clock shake her bed at Mississippi State College for Women. And when Welty later got her first paid job in communications, she worked for a radio station in the base of the clocktower at Lamar Life. Published when she was seventy-five, Welty's reminiscences frankly confess the steady and straight-forward progress of time. She knows that the past--when infants had calling cards, the night sky over Jackson was nothing but blackness, and gargoyles graced her father's office building--is past. She even uses a loosely linear structure to plan the three sections of One Writer's Beginnings. "Listening" attends to her childhood years in Jackson; "Learning to See" reviews a journey in 1917 or 1918 to visit her maternal and paternal grandparents; and "Finding a Voice" speaks of her years in college and her first works as a serious writer. But if the whole triptych shows how Welty gained the ears, eyes, and tongue of a storyteller, her fragmented and wayward memories ultimately reject the external organization of clocks and calendars. Her roundabout narrative flows with the casual immediacy of the raconteuring that Twain described as basic to his own Autobiography: "Start it at no particular time of your life; wander at your free will all over your life; talk only about the thing which interests you for the moment; drop it the moment its interest threatens to pale, and turn your talk upon the new and more interesting thing that has intruded itself into your mind meantime" (I: 193). Twain hoped that such formless form might provide the model for all future autobiographies (II: 245). Originally delivered as a series of lectures at Harvard, One Writer's Beginnings shifts and drifts along the most vital currents of the Southern oral tradition. (1) Welty omits sizable portions of her life and travels through her past without being restricted by fidelity to historical sequence. The problem with organizing her memories according to the rigid succession of years is the same as the problem with the rigorous windows that the narrator of Welty's quasi-autobiographical "A Memory" wants to impose on the transiency and turbulence of her girlhood. Both devices overlook Welty's discovery that greater than any perspective is "a single, entire human being who will never be confined in any frame" (90). …


A flood risk management plan is being developed for the Thames Estuary, covering the next 100 years. In 2007 flood risk management options (the 'High Level Options') were developed for a range of different climate change scenarios. The objective was to provide initial flood risk management options for the estuary, and identify how the uncertainties of future climate change could be managed.
Since then the options have been further developed to take into account other drivers including the deterioration of the existing flood risk management assets. Whilst the Plan will lead to preferred options for managing flood risk, it is recognised that the assumptions used to develop these options could change. The paper demonstrates how the options would be adapted to change.

Whilst the main options have been developed to manage flood risk for the whole estuary, there are choices to be made at the local or Policy Management Unit (PMU) level. Hence the approach applies to both the estuary-wide and PMU levels.


DISSIPATION OF THERMAL ENRICHMENT OF STROMWATER MANAGEMENT PONDS Farshid Sabouri Advisor: University of Guelph, 2013 Professor B. Gharabaghi The intent of this research was to gain a better understanding of the effects of the design parameters on the thermal impact of stormwater management wet ponds. The effect of upland areas on inlet water temperatures of the ponds, thermal design modeling of the ponds, and cooling trenches effects to mitigate stormwater ponds are investigated using data collected from six stormwater ponds in the cities of Guelph and Kitchener, Ontario, Canada. The sensitivity analyses of the developed predictive artificial neural network (ANN) model showed that the rainfall event mean temperatures significantly influenced stormwater temperatures at the inlet of the ponds. The longest pipe length and pipe network density are the two parameters that control the cooling effect of the underground storm sewer system, as opposed to the impervious percentage of the catchment. Concerning the key design parameters of stormwater ponds, larger permanent pool volumes tend to release the warmer water resident in the ponds. Increasing travel path ratio using baffles can lead to less mixing of the water that is resident in the pond with the cooler fresh event runoff and therefore an increase in event mean temperature of outlet. Increasing pond volume from 2000 to 4000 m3 while keeping all other parameters constant results in an average increase of 5 °C in event mean temperature at the pond outlet (EMTO); increasing travel path ratio from 0.6 to 1.2 leads to an average increase of


The article is dedicated to the rationalization of the theoretical grounds applied when implementing the innovation principles targeting improvement of the tourism and hospitality competitiveness of the region in the conditions of sustainable development as a strategic priority of the regional socio-economic development of Russia. The study attempts assessing Russian tourism competitiveness based on the data of the World Economic Forum ( The Travel and Tourism Competitiveness Report 2017 ) and, thus, maintains that the Travel and Tourism Competitiveness Index (TTCI) is based on 15 variables grouped as 4 subindices that define the opportunities for business development in the country, state policy, infrastructure and available natural and cultural resources. Innovative transformations in the regions are to target the development of the international tourism, which implies focusing on the projects ensuring competitive advantages in the global tourism industry. The competitive ability of a regional hospitality market is seen as its ability to create unique innovative economic, organizational and technological environment for tourism product development, provided the adequate productivity is achieved in the international competitive environment in comparison to the tourism regions around the world.


[Objective] To explore treatment of postoperative functional delayed gastric emptying (FDGE or PGS postsurgical gastroparesis syndrome), [Mothod] 20 cases (patients with PGS) were treated mainly by Wuling San (powder of five medicinal herbs). [Result] Of the 20 patients, 5 (33.3%) recovered in one week, 12 (80%) in two weeks, 14 (93-3%) in three weeks, and all the 15 (100%) 1 in four weeks. [Conclusion] Postsurgical gastroparesis syndrome can be cured by conservative therapy such as Wuling San.


Society is daily influenced by analytical measurements on which legal, commercial and social decisions are based. The accuracy of a chemical measurement is fundamental, depending on its purpose, but it becomes still more important when analysis concerns the state of the environment and human health. Industrialised countries generally spend about 6% of their gross internal balance on measurements and related operations. Much of these costs are wasted as they duplicate analysis already performed and relate to untraceable analytical data.


The screw feeder design for the pre-compaction of bulk materials to be briquetted in a roll press is considered to increase the overall reliability. The relationship between the parameters of the screw feeder and its technological characteristics is investigated by the example of two fine-grained materials. A new mathematical model and design algorithm have been developed, which takes into account the properties of materials, the roller press parameters, the shape of the briquettes, and their deformation after compaction. The relationship between the pre-compaction pressure and the material stack height at the inlet is determined. The relations between the torque, the screw pitch, and the material stack height above the inlet, as well as the drive power and the screw pitch on productivity, are investigated. In experiments, using the proposed design, the compaction ratio of the peat increases by 22-27%, and hydrolyzed lignin – by 14-17%.

Objective: Recent sham-controlled andomised clinical trials have confirmed the safety and efficacy of catheter-based renal denervation (RDN) with clinically meaningful blood pressure (BP) reductions in hypertensive patients on or off antihypertensive medication. Longer-term safety and efficacy data have so far only been documented out to 3 years. Here we provide a first report on safety and efficacy outcomes in a cohort of patients with resistant hypertension beyond 5 years of follow up. Design and method: We recruited patients with resistant hypertension who were previously enrolled in various RDN trials applying radiofrequency energy to ablate the renal nerves using the Symplicity Flex® system. All participants had baseline assessments prior to RDN and repeat assessment at current long term follow up including medical history, automated office and ambulatory BP measurement, and routine blood and urine tests. Results: A total of 60 participants (age: 70.0 ± 10.3 years (mean ± SD), 76.3% male) have completed long-term follow up investigations with an average of 6.8 (range 6–10) years post-procedure. Ambulatory systolic BP was reduced by 12.0 ± 21.6mmHg (from 145.7mmHg to 132.8mmHg; p < 0.001) and diastolic BP by 8.3 ± 12.8mmHg (from 81.6 mmHg to 72.0 mmHg; p < 0.001). This BP reduction occurred despite participants being on less antihypertensive medication with a reduction in the average defined daily dose, the assumed average maintenance dose per day for a drug used for its main indication in adults, from 4.91 ± 0.37 to 4.02 ± 0.27 (p < 0.01). eGFR remained stable at long-term follow up with no statistically significant difference in participants with pre-existing CKD from baseline. Conclusions: Our investigation indicates a significant and robust reduction in ambulatory systolic and diastolic blood pressure, despite reduction in antihypertensive medications, in the long-term following catheter-based renal denervation without evidence of adverse consequences on renal function.


Hidden hearing loss (HHL), an auditory dysfunction that has gained much recent attention, has the hallmarks of speech discrimination and intelligibility deficits with normal or near-normal hearing thresholds. The pathological mechanisms of HHL are complicated and are not yet fully understood. HHL can be resulted from disorders of the central nervous system such as auditory cortex, and/or pathological changes of inner ear. Thus far, 2 pathological phenomena, synaptopathy and auditory nerve demyelination, have been reported as underlying causes of otogenic HHL. Here, we review the clinical and physiological characteristics of HHL as well as the molecular pathological mechanisms of otogenic HHL and aim to allude to potential therapy targets for clinical applications in the future.

Recently many space-time coding schemes for multiple antenna systems (MIMO) have been proposed in order to achieve high data rates when transmitting over wireless channels. However, most of such schemes rely on maximum likelihood (ML) detection, which can become quite complex when many antennas are involved and higher modulation schemes are utilized. On the other hand, the high diversity gains of MIMO channels are easily lost when low-complexity receivers like ZF or MMSE are applied. It is thus of utmost importance to look for low-complexity receivers which achieve almost ML performance. In this paper, a new scheme for approximate ML detection for typical flat Rayleigh fading channels is proposed, achieving ML performance in the area of bit error ratio between 10/sup -4/ and 0.1 as it is of interest in wireless communications. The proposed scheme allows the transmission of 64QAM schemes on 4/spl times/4 antenna schemes with a detection complexity of only 1% of a brute force ML receiver.


Industrial development has significant impact on environment in China, thus causing social and economic concerns. In order to understand and examine the impact of industrial structure on pollution, this paper uses panel data of 259 cities in China over 2004-2017 and dynamic panel regression to investigate the relationship between industrial structure and pollution. The result shows that industrial structure optimization decreases pollution. The regression result indicates that 1% industrial structure change can reduce 0.46%, 0.25% and 0.08% pollution of sulfur dioxide, industrial dust and waste water.

The health status of animals held in captivity depends on many factors like: diet, environment, enclosure conditions and animal management. Since one of the main causes of death in wild animals are parasitic infections, regular parasites control and antiparasitic treatment are of great importance in zoo animals. Our study presents an overview of parasites found in animals kept at Skopje Zoo, Macedonia, from 2007 to 2009. Parasite detection was done by fecal analysis using ZnSO4 flotation method. The most common parasites identified were Toxocara sp., Toxascaris leonina, Strongyloides sp., Trichostrongylus sp. and Eimeria sp. In 2007 the percentage of infected animals was 21.4%. In 2008 the percentage of infected animals was about 32.14% and in 2009 it was 28.57%, which is relatively high. The reconstruction of the enclosures during the past three years, when many animals were transferred from one enclosure to another and were mixed with other species of animals, probably caused such a high percentage of parasitic infection. With an appropriate program of antiparasitc treatment and measures to prevent parasitic infection, this percentage can decrease.


Special joint systems are obtained by means of mechanical fasteners located in semi-hollow parts of aluminium extruded shapes. The aluminium industry showed great interest on these joints due to many advantages: easiness, simplicity, rapid execution, material optimisation and machining reduction. A typical case of these special joints, namely screw port, consists of a screw engaged in a slot of an extruded profile. Screw port joints are used in several structural and non-structural applications such as façades, door and window frames. Nevertheless, no clear design rules are provided by aluminium structural codes. For this reason, an experimental campaign aimed at assessing the influence of different geometrical and mechanical parameters on the pull-out behaviour of screw port connections has been carried out at the University "Federico II" of Naples. In addition, on the basis of experimental results, non-linear finite element models have been developed and calibrated in ABAQUS environment.

Based on the improved quantum molecular dynamics model,the incident energy dependences of dynamic potential barriers in the entrance channel of fusion reaction are investigated.It is found that the lowest dynamic barrier is obtained which approaches to the adiabatic static barrier with the incident energy decreasing and the dynamic barrier goes up to the diabatic static barrier with increase of the incident energy.A new explaining of tunneling process for the fusion at the incident energy below the static and above the lowest dynamic barrier is presented.In order to understand the energy dependence of the dynamical barrier we also pay a great attention to study the neck formation and shape deformation during the dynamic lowering of the barrier.


Firstly, a comparison of overall performance between minimum-order augmented pipelining (MAP) clustered look-ahead (CLA) filters and scattered look-ahead (SLA) filters is extensively achieved. From the results, the MAP algorithm is revealed to have a problematic domain searching procedure for finding optimized pipelining coefficients. To solve the problems and improve the numerical performance, we propose an improved MAP (IMAP) algorithm, which is especially beneficial for high-Q ultra-high-speed digital filters. The IMAP algorithm is optimized in the aspect of the minimization of augmented pipelining order and undesirable quantization effects simultaneously. Performance of IMAP is compared with that of the conventional MAP algorithm, to demonstrate the advantage of the IMAP algorithm.

A detailed description including analysis of chaetotactic pattern of larvae of two spiders is given for the first time. Bathyphantes eumenis (KOCH, 1879) and Trochosa ruricola (DE G EER, 1778) - species belonging to different far-related superfamilies (Araneoidea and Lycosoidea) were chosen for the comparative studies. Nomenclature of setae occurring on the larval integument is proposed. Both species examined showed some chaetotactic complexes to be homologous.


Thermal comfort is among the chief indicators of the sustainability of outdoor spaces. However, the complex nature of comfort represents the interaction of several determinants that leads to a perception of the thermal environment. Recently, researchers have paid particular attention to non-physical factors to understand the mechanisms involved in thermal perceptions in urban environments. The extant literature has contended that culture and cultural background are determinants to individuals' thermal perceptions. Therefore, this study aimed to review how the link between outdoor thermal comfort (OTC) and cultural background is investigated. This is, to the best of our knowledge, the first review study on the subject. The study used a systematic literature review approach based on secondary data available in relevant and contemporary literature. The findings first showed the scarcity of research on cultural background and OTC; however, all studies identified corroborated the significant impact of cultural background on thermal perceptions. Notably, the cultural background was found to be the source of variation in thermal perceptions, tolerance to, and preference for certain thermal conditions, thermal comfort requirements and expectations, choice of clothing, and environmental attitudes. The findings provide a sound basis for future researchers to address the research gaps identified. The study also raises policy makers' and designers' awareness of urban environment users' genuine needs and requirements.


Introduction: People with traumatic brain injuries (TBIs) commonly report memory impairments which are persistent, debilitating, and reduce quality of life. As part of the Rehabilitation of Memory in Brain Injury trial, a cost-effectiveness analysis was undertaken to examine the comparative costs and effects of a group memory rehabilitation program for people with TBI. Methods: Individual-level cost and outcome data were collected. Patients were randomized to usual care (n=157) or usual care plus memory rehabilitation (n=171). The primary outcome for the economic analysis was the EuroQol-5D quality of life score at 12 months. A UK NHS costing perspective was used. Missing data was addressed by multiple imputation. One-way sensitivity analyses examined the impact of varying different parameters, and the impact of available cases, on base case findings whilst non-parametric bootstrapping examined joint uncertainty. Results: At 12 months, the intervention was GBP 26.89 (USD 35.76) (SE 249.15) cheaper than usual care; but this difference was statistically non-significant (p=0.914). At 12 months, a QALY loss of −0.007 was observed in the intervention group confidence interval (95% CI: −0.025–0.012) and a QALY gain seen in the usual care group 0.004 (95% CI: -0.017–0.025). This difference was not statistically significant (p=0.442). The base case analysis gave an ICER of GBP 2,445 (USD 3,252) reflecting that the intervention was less effective and less costly compared to usual care. Sensitivity analyses illustrated considerable uncertainty. When joint uncertainty was examined, the probability of the intervention being cost-effective at a willingness-to-pay threshold of GBP 20,000 per QALY gain was 29 percent and 24 percent at GBP 30,000. Conclusions: Our cost-utility analysis indicates that memory rehabilitation was cheaper but less effective than usual care but these findings must be interpreted in the light of small statistically non–significant differences and considerable uncertainty was evident. The ReMemBrIn intervention is unlikely to be considered cost-effective for people with TBI.


To overcome the shortage of traditional rear axle compliance steering (RACS) technology, a kind of viscoelastic smart material is introduced into the rear suspension of a vehicle to construct rear wheel semiactive steering system. This article focuses on the nonlinear dynamic behavior of the vehicle with RACS incorporating viscoelastic smart material. First of all, considering the tire nonlinearity and the fractional derivative constitutive relation of the viscoelastic material, the nonlinear dynamic model of the vehicle with RACS is formulated. Then, the lateral dynamic behavior of the vehicle with RACS is demonstrated through numerical experiments. Finally, some factors that influence shimmy of the compliance steering wheel are investigated. Numerical results demonstrate the Hopf bifurcation characteristics of the vehicle with RACS and disclose the influence factors of Hopf bifurcation characteristics for the vehicle with RACS, which lay the theoretical foundation for the development of the rear wheel semiactive steering technology.
