Composite thermal-barrier elements (TBEs), produced by advanced technologies including explosion welding, pressure treatment and high-temperature treatment, are designed for the separation of media with different working temperatures in cryogenic and power systems. Figure l(a) shows the general view of a TBE produced from bimetal with the continuous channel of complicated shape for pumping a cooling agent, and Fig. l(b) shows a variant of the TBE for a cylindrical container. The general heat-shielding effect of the TBE is the result of the interaction of two factors: the active factor, in the form of a system of channels with the cooling medium changing the temperature fields, and the passive factor, in the form of a laminated intermetallic composite with low


Abstract. Agricultural practices and water resources management in the central highlands of Ethiopia is highly dependant and associated with climatic resources and their pattern and hence wise use of those resources is a priority for the region. Accordingly, a study was conducted to asses and critically quantity the climate resources of the central high lands of Ethiop, Bishoftu district. Thirty three years of weather record data has been used for the work. The onset, duration and end of the growing seasons were defined and quantified based on FAO and Reddy models while the dry and wet spell distributions and the drought events were calculated using the Markov chain models and the standardized precipitation index (SPI) respectively. The results revealed that the mean onset of the main (Kiremt) growing season was found to occur during the second meteorological decade and ended during the end of September. Similarly, though unreliable and only few occurred during the entire study period, the mean onset of the shorter (Belg) season was found to occur during the beginning of the first decade of April. The length of the growing season during the main rainy season, (Kiremt,) ranged from 112 to 144 days with a standard deviation of 9.6 days and coefficient of variation of 7.5%. However, the mean growing length during the Belg season was found to be 22.4 days with a standard deviation of 27 days and coefficient of variation of 122%. The results of analysis obtained both from the Markov Chain and Reddy models indicated higher probabilities of dry spell occurrences during the shorter season (Belg) but the occurrences of the same in the main rainy season (Kiremt) was very minimal. Like wise, the SPI model detected some drought events ranging from mild to severe classes in both seasons based on one a month time scale analysis. A considerable attention of maximizing crop harvest during the main rainy season is practically important.


Abstract : Increasing complexity and shrinking sizes of integrated circuits necessitate the development of new materials and processes to meet current system requirements of high performance and reliability in smaller electronic assemblies. In order to achieve the system performance, materials with incompatible physical and electrical properties are often placed into direct contact with one another. Applications such as area array interconnection of Si devices using lead/tin solders, vias in Si integrated circuits and gold contacts to GaAs circuits require the use of barrier metals to physically and chemically separate materials that would otherwise react and form undesirable by-products or significantly decrease the reliability of the electronic system. This effort was initiated in order to advance the understanding of basic mechanisms and influences of processing on the performance of barrier metals. Deposition of the barrier metals was conducted using physical vapor deposition, unique barrier metal alloys that could not be fabricated by thermodynamic equilibrium methods were developed. Characterization of the processing and materials was performed to better understand the essential mechanisms required for high quality barrier metals.

This paper describes the optimum thickness of barrier metals and the cause of the decrease in the shear strength of 37Pb/63Sn solder bumps for flip-chip interconnection. The authors evaluated the mutual diffusion and the shear strength of solder bumps on barrier metals. From aging test results with the Cu/Ti structure, when the thickness of the Cu film was greater than 10 /spl mu/m, the shear strength did not change from the initial value. In the Ni/Ti structure, where the Ni film had a thickness of 1.0 /spl mu/m, the shear strength also did not change from the initial value. In addition, it was confirmed that the decrease in the shear strength is caused by diffusion between Sn and Cu, or Sn and Ni, and oxidization of the barrier metals.


Abstract 1. The latex of Abiarana gutta-percha is more stable than that of Hevea. In the absence of preservatives Abiarana latex is stable for many months, while Hevea coagulates readily in a few hours. On addition of electrolytes, Abiarana only creams up and is readily and reversibly redispersed; Hevea is coagulated jrreversibly. Under the influence of the electric current Abiarana does not form a coherent skin on the anode; Hevea does so easily. 2. The stability of Abiarana latex is due to a protecting substance reversibly adsorbed on the particles. This substance may be removed by allowing the particles to cream-up repeatedly and by separating the serum from the particles. The serum of Abiarana (or the whole latex) added to Hevea latex strongly protects the latter and causes it to behave like Abiarana latex. 3. A similar protecting action in small concentrations cannot be produced by substances such as gelatin, peptones, lysalbinic acid, starch, etc. The chemical nature of the protecting substance coul...


Introduction/Background: X-linked-dominant hypophosphatemia (XLH), formally known as vitamin-D-resistant rickets, is a rare, hereditary, chronic and progressive skeletal disorder, often perceived as a childhood disease only. Its estimated prevalence is 1 in 20,000. The perception that XLH does not require treatment once the growth plates fuse means that many adolescents/young adults (AYA) are lost to follow-up and then seek care for chronic musculoskeletal symptoms, including the consequences of osteomalacia (bone pain, pseudofractures, fractures) during adulthood. There is a need to improve the healthcare transition (HCT) preparation for AYA with XLH and other rare metabolic bone disorders (MBD) to facilitate consistent and effective care throughout the life span and lessen the psychosocial and economic burden associated with these disorders.
 Methods/Statement of the Problem: HCT timelines, milestones, and educational tools exist for some chronic conditions such as diabetes or kidney disease, but these programs do not meet the unique needs and nuances of patients with XLH and other rare MBD as they transfer to adult-focused healthcare. Consequently, specific tools and resources tailored by disease experts for these AYA are needed.
 Results/Proposed Solution: Detailed timelines with milestones and a description of a HCT program for AYA with XLH and other rare MBD have been adapted from best practice protocols. This program reflects the specific needs of, and complexities associated with these conditions. Furthermore, this approach describes how to facilitate better communication between adult- and pediatric-focused providers and their interdisciplinary teams. Our approach is guided by patient/caregiver input and existing models for research/clinical care, with the use of validated tools to measure HCT readiness. We identified the need for psychosocial and access-related resources for AYA emancipation from parental involvement, including a guidance document for parents on how to empower their child to take ownership of the disease as they grow. In addition, it is helpful to provide disease education, genetic counselling and guidance on family planning, to encourage patients to advocate for their healthcare (as access to specialists may be limited by geographical location), and to facilitate communication/education to patients through channels familiar to and accepted by AYA (e.g. online portals, text messages). Clear HCT preparation guidelines and treatment-related goals are defined for all stakeholders. A portfolio of supporting materials underpins optimization of outcomes as AYA with XLH and rare MBD transfer from pediatric- to adult-focused healthcare.
 Conclusion: Development of HCT tools/resources specific to XLH and other rare MBDs can help prevent loss to follow-up and promote continuous clinical care, thus driving better outcomes for AYA with these conditions.

Holograms of large objects may be formed by using several coherent low-intensity laser sources. If several low intensity laser sources are available, they can be applied simultaneously. Each source is then used to establish one object beam and one reference beam whose path lengths are equal, recording a small portion of the total object.


Objective: to evaluate the efficiency of a comprehensive rehabilitation program (CRP) in patients with early rheumatoid arthritis (RA) for 6 months. Subjects and methods. Sixty patients with early RA were examined. During medical therapy, 6-month CRP was implemented in 34 patients in the study group. The 2-week in-hospital stage involved ten sessions of 15-min local air cryotherapy (-60 °C) of the hands, knee or ankle joints; ten classes of 45-min therapeutic exercises (TE) under the supervision of a trainer; ten sessions of 45-min ergotherapy (training people how to therapeutically position their joints, to apply their protective methods, to lift and move things, to use assistive devices, and to do hand exercises); orthotics (working wrist orthoses, knee ones, or individual orthopedic insoles); and four 90-min educational program classes. The outpatient and domiciliary stages included 45-min TE thrice weekly; creation of a correct functional stereotype; and orthotics. Twenty-six patients received medical therapy only (a control group). The authors estimated tender joint count (TJC), swollen joint count (SJC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), joint pain on 100-mm visual analog scale (VAS), DAS28, HAQ, RAPID3, hand grip strength, average maximum knee extension and ankle flexion by the EN-TreeM movement analysis, and compliance with drug and non-drug treatments. Results. The study group showed a stably high compliance with therapy with disease-modifying antirheumatic drugs, less need for symptomatic agents, higher adherence to the methods of creating a correct functional stereotype, orthotics, and regular TE. Twenty-two patients completed 6-month CRP; 12 patents did not complete the treatment because of non-compliance with nondrug methods, primarily TE. Upon completion of the in-hospital stage of CRP, the study group exhibited significant positive changes in pain and functional status and no significant impact on global inflammatory activity indicators (SJC, ESR, CRP, and DAS28). After 6 months of CRP, there were reductions in TJC by 6.0+1.8 or 72.3% (p <0.01), SJC 4.0+1.2 or 74.1% (p <0.01), ESR by 58.2% (p < 0.01), CRP by 67.2% (p < 0.01), VAS pain by 70.4% (p < 0.01), DAS28 by 1.38+0.21 scores or 31.9% (p < 0.05), HAQ by 0.97+0.56 scores or 75.8% (p < 0.01), and RAPID3 by 5.98+0.92 scores or 60.1% (p < 0.01). The grip strength of a more and less affected hand increased by 44.9% (p < 0.05) and 31.3% (p < 0.05), respectively. The average maximum extension of a weaker and stronger knee joint increased by 88.7% (p < 0.01), and 67.7% (p < 0.01), respectively. The average maximum flexion of a more and less affected ankle joint rose by 81.6% (p < 0.01) and 70.2% (p < 0.01), respectively. Following 6 months, the changes in the control group were less significant, which determined significant differences between the groups in most indicators. Conclusion. Six-month CRP enhances compliance with drug and non-drug treatments, assists in controlling disease activity, and improves functional abilities, motor activity, and quality of life in patients with early RA. The main reason for CRP interruption is inadequate patient adherence to non-drug treatments.


This study presents the police forces in Hungary during the Austro–Hungarian Empire, complete with an analysis of the period  between the two world wars. The presentation of organization and structure aims to introduce and analyze the system of relations  mainly between the Catholic Church and the police  forces.

The  goal is to prove that pastoral care, established  through the cooperation between the  institutions of  pastoral care and the armed forces, was operating  within an effective framework during the period  encompassing the  two world wars.


School education encourages students to excel in development with consciousness of competition, and in the mean time, the ordinary mentality should also be cultivated in education. With ordinary mentality, the goals of life's ideal can be better realized, psychological embarrassment can be rationally adapted, interpersonal harmony can be realized to the maximum, and the meaning of life can be truly perceived; whereas the formation of non-ordinary mentality is mainly out of personality defect, and is also out of the exaggerated awareness of pressure of existence, of the stimulation of harmful cultural elements, and of biased spiritual guidance in school education. To lay importance to ordinary mentality cultivation, the wisdom education in total education should be strengthened to raise students' capability in cultural judgment, to guide young students' cultural psychological orientation, and to make adjustments in the aspects which are liable to form negative influence on students in current education administration.

Wireless device Network (WSN) is basically arrangement of distinct and dedicated sensors for observation and recording the healthiness of the surroundings and organizing the collected information at a central location. While several protocols for detector network security offer confidentiality for the content of messages, discourse info typically remains exposed. To conserve user location privacy, spatial and temporal cloaking techniques are the foremost ordinarily used technique in Location based mostly Services. Existing techniques defend the leakage of location data from a restricted opponent who will solely observe network traffic in a very tiny region. In previous papers, it was addressed the importance of location privacy of both the source and sink and propose four schemes called forward random walk (FRW), bidirectional tree (BT), dynamic bidirectional tree (DBT) and zigzag bidirectional tree (ZBT) respectively to deliver messages from source to sink, which can protect the end-to-end location privacy against local eavesdropper. Through analysis and simulation, we tend to demonstrate that the suggested techniques are efficient and effective for source location privacy in sensor networks.

The 'psychiatric importance of pellagra The psychiatric importance of pellagra is considerable. It has been estimated that from 4 to 10 per cent of all pellagrins show mental symptoms (Henderson and Gillespie, 1940). In England, pellagra has been noted in lunatic asylums since 1913. There were 21 deaths from pellagra in 1922, mostly from the Lancashire Mental Hospital, Rainhill and during the period 19 3 to 1918 there have been 104 deaths from pellagra among the asylum inmates. Goldberger found that in certain asylums in tho United States the number of lunatics developing pellagra each year was a constant proportion of the total (Manson-Bahr, 1940). Conditions are however quite different in the mental hospitals of this country. It is interesting to note that during the period 1936 to 1940 not a single case of pellagra has been reported from the Indian Mental Hospital, Kanke,. which is the biggest mental hospital in this country and caters for the three provinces of Bihar, Bengal and Orissa (Dhunjibhoy, 1938, 1939, 194

We present the results of analytical evaluation of the indirect RKKY interaction in a layered metal with nearly nested (almost squared) Fermi surface. The final expressions are obtained in closed form as a combination of Bessel functions. We discuss the notion of the
``2k_F'' oscillations and show that they occur as the far asymptote of our expressions. We show the existence of the intermediate asymptote of the interaction which is of the sign-reversal antiferromagnetic type and is the only term surviving in the limit of exact nesting. A good accordance of our analytical formulas with numerical findings is demonstrated until the interatomic distances. The obtained expressions for the Green's functions extend the previous analytical results into the region of intermediate distances as well.


Abstract Utilization of wind energy is a promising way to generate power, and wind turbine blades play a key role in collecting the wind energy effectively. This paper attempts to measure the deformation parameter of wind turbine blades in mechanics experiments using a videometric method. In view that the blades experience small buckling deformation and large integral deformation simultaneously, we proposed a parallel network measurement (PNM) method including the key techniques such as camera network construction, camera calibration, distortion correction, the semi-automatic high-precision extraction of targets, coordinate systems unification, and bundle adjustment, etc. The relatively convenient construction method of the measuring system can provide an abundant measuring content, a wide measuring range and post processing. The experimental results show that the accuracy of the integral deformation measurement is higher than 0.5 mm and that of the buckling deformation measurement higher than 0.1 mm.


Facilitating and empowering learners and teachers through technology has primarily concentrated on content and management aspects rather than on assessments aspects of the education enterprise. ecent developments in virtual world technology have sparked a raft of projects exploring the possibilities to enhance learning outcomes. In this article, automated support for educational assessment is focussed on via three case studies implemented in Second Life, the 3D virtual world implemented by Linden Labs. This paper discusses the assessment tasks, the methods used and provides an analysis of our results. The University of Hamburg case study involves scenario-based software development projects. The Curtin University case study focuses on simulating the business processes of the Automated Assessment Lab, which provides automated assessment opportunities to staff of the Curtin Business School, and in which a virtual world model of the entire assessment life cycle is created. A third case study from the University of New England, VirtualPREX (Virtual Professional Experience), explores self, peer and academic formative and summative assessment in virtual world role-play scenarios. Each case study comprises a description of intent and implementation, followed by evaluative comments from the role players, providing insight into the benefits that may accrue from the use of virtual world technology for students, teachers and educational administrators.


In order to develop a molecular method for detection and identification of Xanthomonas campestris pv. viticola (Xcv) the causal agent of grapevine bacterial canker, primers were designed based on the partial sequence of the hrpB gene. Primer pairs Xcv1F/Xcv3R and RST2/Xcv3R, which amplified 243- and 340-bp fragments, respectively, were tested for specificity and sensitivity in detecting DNA from Xcv. Amplification was positive with DNA from 44 Xcv strains and with DNA from four strains of X. campestris pv. mangiferaeindicae and five strains of X. axonopodis pv. passiflorae, with both primer pairs. However, the enzymatic digestion of PCR products could differentiate Xcv strains from the others. None of the primer pairs amplified DNA from grapevine, from 20 strains of nonpathogenic bacteria from grape leaves and 10 strains from six representative genera of plant pathogenic bacteria. Sensitivity of primers Xcv1F/Xcv3R and RST2/Xcv3R was 10 pg and 1 pg of purified Xcv DNA, respectively. Detection limit of primers RST2/Xcv3R was 104 CFU/ml, but this limit could be lowered to 102 CFU/ml with a second round of amplification using the internal primer Xcv1F. Presence of Xcv in tissues of grapevine petioles previously inoculated with Xcv could not be detected by PCR using macerated extract added directly in the reaction. However, amplification was positive with the introduction of an agar plating step prior to PCR. Xcv could be detected in 1 µl of the plate wash and from a cell suspension obtained from a single colony. Bacterium identity was confirmed by RFLP analysis of the RST2/Xcv3R amplification products digested with Hae III.

We consider a subclass of bipartite CHSH-type Bell inequalities. We investigate operations which leave their Tsirelson bound invariant, but change their classical bound. The optimal observables are unaffected except for a relative rotation of the two laboratories. We illustrate the utility of these operations by giving explicit examples. We prove that, for a fixed quantum state and fixed measurement setup except for a relative rotation of the two laboratories, there is a Bell inequality that is maximally violated for this rotation, and we optimize some Bell inequalities with respect to the maximal violation. Finally, we optimize the qutrit to qubit ratio of some dimension witnessing Bell inequalities. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to '50 years of Bell's theorem'.

Triplicate lots of fingerling lake trout (Salvelinus namaycush) (initial mean weight, 5.3 g) were fed a basal, semipurified diet, or this basal diet supplemented with either 1.0 or 2.0 ppm of either menadione sodium bisulfite (MSB) or menadione dimethylpyrimidinol bisulfite (MPB) for 18 wk at 14 C. Neither form of vitamin K had a significant effect on the growth, food conversion, or body composition of the fish.Fish fed 1 ppm of MSB had a significantly higher mean packed cell volume (PCV) than those fed 2 ppm of either analogue. Trout fed 2 ppm of MPB had an intermediate PCV which was not significantly different from that of trout fed either 1 ppm MPB or 2 ppm MSB. A dietary level of 1 ppm MPB (providing an equivalent menaquinone concentration of about 0.5 mg/kg of diet) is sufficient to insure normal coagulation of lake trout blood and a satisfactory PCV.

Background: The supracervical hysterectomy is no longer indicated for the treatment of female genital disease. Patient and Methods: All women who had trachelectomy after supracervical hysterectomy between 2010 and 2020 had their records reviewed at Cairo University's National Cancer Institute (NCI) Hospital. Results: A total of 34 trachelectomy surgeries were performed during a ten-year period. The patients were 42 to 72 years old, with a mean +SD of 55+7.5. Recurrent vaginal bleeding was the reason for trachelectomy in 67.6% of cases due to residual disease found in hysterectomy specimens, with pathologic evidence of uterine malignancy in 47.2%, and 11.7 percent of patients had cervical malignancy. Uterine stromal sarcoma was found in 5.9% of the cases. There were 11.8% of cases with uterine fibroids, 7.8% with endometrial hyperplasia, and 2.9 % with uterine adenomyosis who had true benign lesions. There were no pathology reports available in 8.8% of the cases. The pathology of the trachelectomy revealed that 26.5% of patients had no residual disease, while 73.5% had the residual disease in the cervical stump, with 32.4% having cervical squamous cell carcinoma, 20.6% having uterine adenocarcinoma, 8.8% having cervical adenocarcinoma, and 2.9% having cervical adenosquamous. Mullerian carcinoma was found in 2.9% of the cases, whereas undifferentiated carcinoma was found in 2.9%. In 61.8% of cases, bilateral pelvic lymphadenectomy was coupled with trachelectomy for radical excision of gross malignancy. Conclusions: A significant number of patients who had a subtotal hysterectomy for apparent benign illness required trachelectomy within a few months.


In the era of knowledge economy, the value network becomes a more effective way of the corporate value creation. This article initially reveals the relation between the value chain and the value network by the graphs; then discusses the process in which the value network exerts an influence on the knowledge transformation and explores the effective knowledge resources allocation on the platform of the value network to create the corporate core competitive capability.


A novel all optic fibers Q-modulated erbium-doped optic fibers laser is reported. The optic fibers ring mirror with optic fibers grating is used as Q-modulation device in its configuration. Both functions of intracavity loss modulation and selection of laser output wavelength are simultaneously provided by this Q-modulation scheme. Compared with acousto-optic and electro-optical Q-modulation, etc., its output pulse is wider. The loss of all optic fibers Q-switch unit welding with optic fibers is small and thus overcomes the fault of high inserting loss when volume optical modulator joining with optic fibers.


Detection of partial discharge (PD) signals is one of the most important methods for predictive maintenance of gas insulated switchgears (GIS). Because type of PD source, configuration of a GIS tank and frequency response of a sensor influence a PD spectrum, detected PD pulse has a specified frequency spectrum. Although frequency spectrum is one of valuable information for PD in a GIS, the spectrum measured with spectrum analyzer or FFT processing is generally a result of averaging of many signals so that statistical features of PD are lost. In addition, frequency spectrum is complex and special experience is needed to recognize it. Thus convenient method is required to discriminate various PD pulses. In this paper, we attempt to extract two frequency components from a PD pulse and to process them in order to categorize it easily. Correlation between pulse heights of two frequency components and pulse height distribution resolved with power voltage phase are shown as effective methods to distinguish the type and the location of PD sources.

The LED lamp provided by the utility model overcomes the defects of the prior art, avoids glare, flicker, dazzling, light spots and the like, and realizes uniform space illumination.


TRUCK WEIGHT DATA TAKEN IN 1960 THROUGH 1963 BY THE PLANNING SURVEY DIVISION OF THE TEXAS HIGHWAY DEPARTMENT WAS ANALYZED. LOADOMETER STATIONS WERE GROUPED ACCORDING TO DIFFERENT PARAMETERS. EQUIVALENT 18-KIP SINGLE AXLE APPLICATIONS WERE CALCULATED AT EACH OF THREE LOCATIONS USING EACH OF THREE PROCEDURES FOR ESTIMATING AXLE WEIGHT DISTRIBUTION. TRUCK TRAFFIC CHARACTERISTICS OF SEVEN TYPES OF TRUCKS WERE REPORTED.


In this paper, the sliding mode control problem for Markovian jump systems (MJSs) subject to parameter uncertainties and disturbances is solved via an event-triggered scheme. Firstly, a sliding mode surface is constructed, and then sufficient conditions are given to ensure the stochastic stability of the resultant Markov jump sliding mode dynamics. Secondly, the system trajectories of the considered MJSs are driven onto the quasi-sliding mode band by synthesizing an event-triggered sliding mode controller. Moreover, the event-triggered scheme is developed together with the design of sliding mode controller, which is different from the most existing work. Further, the value of the quasi-sliding mode band is also given by calculation. Particularly, the introduction of event-triggered scheme is capable of saving the network bandwidth utilization while maintaining a satisfactory system performance. Finally, the effectiveness of the presented approach is illustrated by utilizing a practical DC motor model.


In this study, we investigated the links between peat carbon accumulation and past ecological and hydrological conditions in three peatlands (Bouleau, Mista, Auassat) which developed along a South-North transect within a watershed encompassing the boreal and subarctic domain in Eastern Canada. Peatland development and long-term apparent rates of carbon accumulation (LORCA) were asynchronous in the watershed, suggesting an influence of both latitude and topography (altitude) on the length of the growing season (GGD0). Results show that peat initiation within the three peatlands (respectively ca. 9070, 8400, and 6270 cal BP) was delayed after the deglaciation and that LORCA (respectively 35.5, 15.4, and 9.0 g C m−2 yr−1) decreased from South to North. Peatland development and fen to bog transitions were found to be almost synchronous for the two southernmost sites. The fen to bog transition in the northernmost subarctic site was delayed until the 20th century, owing to the less favorable climatic conditions. This suggests that recent warming has extended the length of the growing season and increased Sphagnum growth enough to potentially influence an ecosystem state-shift as observed in other Subarctic regions of eastern Canada.


A pulsar ring for a rotary encoder has a mounting ring (1), a pulsar ring body (2), and a seal ring (3). The mounting ring (1) is made of a non-magnetic material. One end of the mounting ring (1) is fitted into and fixed to an inner ring (202) on the rotation side, and the other end is positioned in proximity to an outer ring (201) on the stationary side with labyrinth-like clearances (G 1 , G 2 , G 3 ) present between the mounting ring (1) and the outer ring (201). The pulsar ring body (2) is molded of a synthetic resin material or rubber-like elastic material mixed with magnetic powder, is magnetized in multiple poles, and is integrally installed on the inner surface of the mounting ring (1). The seal ring (3) is disposed on the inside of the mounting ring (1), is fitted into and fixed to the inner ring (202) with the mounting ring (1) disposed therebetween, and is slidably in intimate contact with the outer ring (201). The construction above makes the magnetic field of the pulsar ring less susceptible to disturbances caused by foreign matters, slurry, and an external magnetic field from the outside, and as a result, the pulsar ring can maintain a stable magnetic pattern.


This work analyzed, via event study methodology, the impact of the disclosure of two relevant decrees in 2020 (1. quarantine in the city of Wuhan by the Chinese government on January 22; 2. COVID-19 pandemic by the WHO on March 11 ) in the cumulative return of the common shares of the four largest Chinese banks by the market value criterion. Event 1 presented p-values greater than 0.05 in the estimation window, showing no statistically significant impact on the behavior of the abnormal cumulative return of selected common shares, characterizing informational inefficiency. For event 2, the opposite is in the days close to the disclosure (p-values lower than 0.05) under the expected behavior of price adjustment in efficient markets.


Background. Materials degrading after implantation into bone are in the field of actual vision of orthopediс surgeon. These materials include polylactides, which are the ideal material for creating bone implants in 3D-printer, especially implants of complex shapes and different sizes. The purpose of the study is to conduct a comparative analysis of bone remodeling under conditions of implantation of polylactide 3D-printed screws into metadiaphyseal and diaphyseal defects of the rat femur. Materials and methods. Comparative analysis of bone remodeling under conditions of implantation of polylactide Ingeo™ Biopolymer 4032D 3D-printed screws into the metadiaphyseal and diaphyseal defects of the rat femur for 15, 30, 90, 180 and 270 days are conducted. After implantation of polylactide, areas of bone with implants were examined by the histological method with the determination of the osteointegration index. Results. It was found that for all the study periods the implants kept their shape, were surrounded by bone tissue. The osseointegration index on the 270th day in metadiaphyseal and diaphyseal defects is 97.1 and 94.3 %, respectively, and is statistically higher compared to the 15th day by 2.2 and 2.3 times (p < 0.001). Conclusions. The polylactide-based Ingeo™ Biopolymer 4032D implants are biocompatible, have high osteointegration qualities, do not cause inflammation in the surrounding soft tissues and bone marrow, do not lead to destructive changes of the bone in the implantation sites. At the end of the study (270 days), the degradation of polylactide is not found, which makes it possible to use it for fixation or filling cavities in compact and spongy bones for a long time.


Abstract In the present work, a novel AWJM-based tool fabrication strategy has been proposed and implemented to make EDM tools. The novelty of the work relies on the proposal of path strategy for jet movement that moves along two parallel paths while keeping the step over (SO) more than the diameter of nozzle (1.25d). The remaining protruded material in between two parallel passes can be utilised as an EDM tool. Following this procedure, micro-tools were fabricated and their geometry was analysed by varying the process parameters: SO, pressure and traverse speed, respectively, on a copper sheet of 6-mm thickness. All the parameters were kept constant in two passes to maintain tool accuracy on all sides. Micro-tools of different shapes (straight, curve) were fabricated. Geometry of micro-tools was measured by 3-D optical profilometer and processed using Vision 64 software. Digital and scanning electron microscopes were used to observe and analyse the microscopic behaviour of the machined surfaces (tool) namely, bottom surface, side wall and top surface. Tools thus fabricated were found to be of good quality except that some abrasive particles were found embedded into bottom surface. The response of the tools was analysed by performing the experiments on an EDM set-up, where the width of the channels was found to be uniform throughout.


With much higher heat transfer rate than conventional heat transfer scheme, impinging jet received great attention from electronic heat engineers and some interested scholars. This kind of heat transfer scheme is of great possibility to become a practical solution to the cooling of high power density micro-electronics equipment. Although with simple boundary conditions, impinging jet is characterized with many complicated flow features, it is almost impossible to obtain analytical flow and heat transfer solution. As to numerical simulation, one severe obstacle is to find a proper turbulent model, because impinging jet simulation result is strongly dependent on the turbulent model adopted. So experiment becomes the most important tool to investigate the heat transfer of impinging jet. In order to obtain the heat transfer coefficient distribution of impinging surface, iso-heat-flux boundary condition was often adopted by former investigators. But ideal iso-heat-flux boundary condition is hard to realize because of the limit of material and manufacturing technology. Impinging jet with nonideal iso-heat-flux boundary condition was modeled by numerical simulation, with standard k-epsiv model as turbulent model, regardless of its strict accuracy on impinging jet. The actual heat transfer coefficient was compared with the calculated result which is based on the hypothesis of ideal iso-heat-flux boundary condition. The influence of nonideal iso-heat-flux boundary condition on calculated results was analyzed. The criterion of judging approximate ideal iso-heat-flux boundary condition is put forward which could be used as guidance for designing impinging surface in impinging jet heat transfer experiment. It can also be used to evaluate the validity of experimental results. Furthermore, the conclusion of this paper can also be applied to other heat transfer experiments with nonuniform heat transfer coefficient

Ionic liquids are generally recognized as highly stable compounds with high thermal decomposition temperatures and wide electrochemical windows. While the former claim has been the subject of recent scrutiny and controversy, comparatively little attention has been paid to another important aspect of ionic liquid applicability: their chemical stability. Bronsted bases constitute an important class of reagents to which ionic liquids are generally sensitive. Due to the positive charge of cations and the resultant polarization of methylene and methine protons in their structure, many ionic liquid cations tend to be weakly acidic and susceptible to either deprotonation or base-induced fragmentation. As a result, several common classes of ionic liquids are incompatible with Bronsted-basic reagents. This is unfortunate due to the wide scope of possible applications of strong Bronsted bases, in fields such as synthesis, catalysis and separations. Nevertheless, several authors have investigated the design of ionic liquids with improved resistance to Bronsted-basic reagents, and numerous reports exist on the stability of the common classes of cations in basic media. This review discusses the existing literature on the alkaline decomposition of ionic liquids.


—Machine learning techniques have been widely adopted to assist in data analysis in a variety of Internet of Things (IoT) systems. To enable flexible use of trained learning models, one viable solution is to leverage all categories of data from different applications to train a general model, which can be further tuned for applications through tuning process. This process incurs additional overhead at the start, but makes later revision and iteration faster and more flexible. Nonetheless, due to limited computing capabilities, IoT devices cannot handle the training process of large datasets. To address this issue, in this paper, we propose a general framework to adopt transfer learning in industrial Internet of Things (IIoT) systems. In our study, we categorize the application space of applying transfer learning to IIoT systems into four generic scenarios: centralized transfer learning with large datasets, distributed transfer learning with large datasets, centralized transfer learning with small datasets, and distributed transfer learning with small datasets. According to the characteristics of each scenario, we design workflows to apply transfer learning technique. To demonstrate the efficacy of the approach, we apply our transfer learning technique to the task of IIoT component recognition. We use the known VGG- 16 model and leverage T-Less industrial datasets to evaluate the performance of our approach in different scenarios. Via performance evaluation, our experimental results confirm the efficacy of our approach, which can not only reduce training time, but also achieve higher accuracy, compared with the classical convolutional neural network (CNN) approach.


The use of an emitter peaked transistor amplifier to provide luminance drive to the cathodes of a large screen color CRT is considered. The linear, small signal characteristics of emitter peaking are analyzed using pole-zero techniques. This theory is then checked by comparing numerical calculations to experimental measurements. The theoretical results in conjunction with certain practical considerations are then used to develop a useful design procedure. This is accompanied by a sample design. Collector peaking circuits are well documented in the literature and will not be discussed in this paper.


Of the whole field of religious studies, one area of consistent interest and activity has been the study of myth; and if any one area has represented the wide variety of approaches scholars of religion have utilized, it is this one. Students of language and literature (e.g. F. Max Müller and J. Campbell), psychology (e.g. S. Freud and C. Jung), sociology (e.g. E. Durkheim and P. Berger), social anthropology (e.g. B. Malinowski, V. Turner and C. Levi-Strauss) as well as religion (e.g. M. Eliade and G. La Rue) have all offered interpretations of myth. An investigation of these various approaches to understanding myth seems to point to the conclusion that the history of the study of myth is a history of reductionism. That is, the heritage transmitted to scholars who would attempt to understand the nature and function of myth within a single discipline is one which most often limits the essential nature or function of myth to that discipline's underlying assumptions alone. Hence, myth is usually linked either to the social or the psychological dimension of human experience exclusively. However, even those theories of myth which combine social and psychological methods and assumptions have usually resulted in truncated conclusions which give pause to those of us who seek their application.


Agriculture industry stakeholders, especially those in oil palm industry, reckon the significance of pursuing sustainability due the competitiveness in the industry. Moreover, rigorous requirements which imposed by sustainable organizations and authorities has given rise to the industry stakeholders for continually seeking for better solutions to minimize the total operating cost. Yet even though these scenarios are what satisfies and act as the market drive to promote the research in precision technologies, the practices of precision technologies in Malaysia's oil palm industries still lack in its pace. This research aims to develop a sustainable precision agriculture management system for the oil palm industry. The research then moved forward to the development of Oil Palm Management System (OPAMS) which serves as a monitoring and data management system to justify the decision making in oil palm plantation operational process to achieve sustainable goal. The system assists them in monitoring, control and properly manages their resources, including fertilizers, chemical, pesticides, energy and water with better efficiency. The research raised the awareness of precision agriculture practices in oil palm industry, allow industry stakeholders taking sustainability into account while making operating investment and management decisions.


One of the problems we face in 4-year engineering technology programs is to motivate students to work on a senior project that is based on the research methodology. Most students choose instead traditional design projects. The design projects are good for integrating knowledge from various courses, but students do not get a chance to work on new innovative areas where they have to learn new ideas and new methodologies. The project described in this paper, although not a new technique, gave the student a chance to work in a research related field. As part of the preparation for the work the student was given basic information required for any research project. A review of various related statistical concepts was also completed. This paper reflects the work done in this senior project course by the student and the advisor. The paper describes two work sampling studies, one each on a residential project and a commercial project.


Bacterial wilt is one of the three bacterial diseases on dry bean in Bulgaria. The disease is caused by the bacterium Curtobacterium flaccumfaciens pv. flaccumfaciens. The bacterium causes stunting, wilting and death of the bean plants. The disease development is favored by hot weather and drought stress. Breeding varieties combining resistance to common bacterial blight, halo blight and bacterial wilt is the main strategy for control of bacterial diseases on bean in Bulgaria; this strategy is incorporated in the breeding program of DAI General Toshevo. In our preliminary study we determined several sources of resistance to individual strains of C.f. pv. flaccumfaciens (Kiryakov and Genchev, 2000). This publication presents results on the testing for resistance of elite accessions and breeding lines of dry bean to bacterial wilt.


Pera glabrata is a widely distributed tree in Brazil. The plant species is important for conservation and restoration of degraded areas due its presence in impacted environments. Besides, the production and the dispersion of large quantities of seeds, provide food supply for many species of animals. Despite its phytosociological importance, there are no studies addressing its reproductive ecology. The objectives of this study are to characterize the reproductive phenology, floral morphology, breeding system and pollination and seed dispersal of the species. The study was conducted in an area of cerrado in Sao Carlos (SP). It was found that Pera glabrata is dioecious, showing massive flowering and the flowers of both sexes are small, involuted, yellow and with diurnal anthesis. The male flowers provide nectar, and emit a sweet odor, while the female ones do not offer visible reward to visitors. The flowers were visited by 32 small species of Diptera and Hymenoptera. Fruits and seeds were developed through autogamy. Twenty-five bird species visited individuals bearing ripe fruits, and 16 species ingested arilate seeds. In conclusion, Pera glabrata is an autogamous species, with several small insects pollination system and ornithocoric dispersal of its seeds.

Chronic back pain (CBP) is one of the major causes for medical consultation among young people. Given the limited sources, it is relevant knowing the characteristics associated with a higher burden in order to prioritize the performance of imaging exams.To identify factors associated with sick leave in a cohort of young patients with CBP awaiting an MRI of the spine.The project "Strategy for a Hospital Early Referral in Patients with Axial Spondyloarthritis" (SHERPAS) is a prospective ongoing study recruiting young patients (18 to 40 years) with CBP that are requested an MRI of the spine by other specialists different than rheumatologists in a tertiary hospital. The study period started in September 2021, and the dataset for this interim analysis was locked in October 2022. Patients completed a questionnaire concerning work status, including sick leave due to CBP (at-visit or prior to this). Besides, socio-demographic and clinical characteristics were collected. Patient-reported outcomes (PROs) for fatigue, Patient Global Assessment (PGA), physical function (Bath Ankylosing Spondylitis Functional Index -BASFI), and overall health (Assessment of Spondyloarthritis international Society Health Index -ASAS HI) were also evaluated. A logistic regression analysis was performed to evaluate the association of patients' characteristics with sick leave.Of 152 recruited patients, 123 (80.9%) were actively employed, 22 (14.5%) were unemployed and 7 (4.6%) were students. Among the employed patients (52.8% female; mean age 33.8(4.8) years; 57.0 (54.0) months CBP duration), 65 (52.8%) patients had been on sick leave at some point (50 prior to visit and 15 at the study visit). Baseline characteristics are shown inTable 1. Night pain was more frequent in patients on sick leave (56.9 % vs 36.2%, p=0.02), and PROs on fatigue, PGA, physical function and overall health and functioning showed worse results in these patients, as compared to patients who had never been in sick leave. Additionally, patients on sick leave had more frequently pharmacological treatment. After multivariable analysis, being male (OR 2.3, 95%CI 1.0-5.6), having night pain (OR=2.4, 95%CI 1.0-5.8) and reporting higher PGA (OR=1.1, 95%CI 1.0-1.4) were associated independently with being on sick leave.One out of two young patients with CBP awaiting an MRI of the spine are on sick leave at some point. These patients have poorer quality of life and use more pharmacological treatment than active patients with CBP. Male sex and night pain are associated with being on sick leave due to CBP and therefore could be used to prioritize the use of spinal MRI aiming to optimize health resources.Table 1.Characteristics of employed patients by work statusTotal employedn=123No sick leaven=58Ever sick leaven=65p-valueDemographicsAge33.8 (4.8)33.6 (5)34.1 (4.8)0.6Symptoms (months)57.0 (54.0)54.8 (54.1)59.0 (54.3)0.7BMI25.4 (4)25.4 (4.2)25.4 (3.7)0.9Female65 (52.8)33 (56.9)32 (49.2)0.5EducationPrimary/secondaryUniversity66 (52.8)56 (45.5)27 (46.5)30 (51.7)38 (58.4)26 (40.0)0.2Type of workSendentary/ not activePhysically active33 (26.8)76 (61.8)19 (32.8)38 (65.5)14 (21.5)38 (58.5)0.5Characteristics of back painButtock pain42 (34.2)17 (29.3)25 (38.4)0.4Night pain58 (47.1)21 (36.2)37 (56.9)0.02Inflammatory pain29 (23.6)14 (24.1)15 (23.1)1Flares of back pain87 (70.7)42 (72.4)45 (69.2)0.8Sudden onset72 (58.5)29 (50.0)43 (66.1)0.1Morning stiffness76 (61.8)32 (55.1)44 (67.7)0.2PROsFatigue (0-10)4.9 (3)4 (3.1)5.7 (2.7)0.002PGA (0-10)4.7 (2.9)3.7 (2.9)5.7 (2.6)<0.001Physical function (BASFI)3.2 (2.6)2.4 (2.3)4 (2.6)<0.001Overall health (ASAS-HI)6.7 (3.8)5.6 (3.6)7.8 (3.8)0.002TreatmentsNSAIDs109 (88.6)52 (89.6)57 (87.7)0.2Muscular relaxants88 (71.5)33 (56.9)55 (84.6)<0.001Opioids45 (36.6)11 (18.9)34 (52.3)<0.001Antidepresants19 (15.5)4 (6.9)15 (23.1)0.01The SHERPAS study has been conducted thanks to an unrestricted grant from Novartis.Diego Benavent Speakers bureau: Janssen, Roche, Galapagos, Abbvie, Grant/research support from: Novartis, Mar Tapia-Viñé: None declared, Daniel Bernabeu: None declared, Victor Muley: None declared, Chamaida Plasencia Speakers bureau: Pfizer, Abbvie, Lilly, Sandoz, Sanofi, Biogen, Roche, Novartis, Grant/research support from: Pfizer and Abbvie, Alejandro Balsa Speakers bureau: Pfizer, Abbvie, Lilly, Galapagos, BMS, Sandoz, Nordic Pharma, Gebro, Roche, Sanofi, UCB, Consultant of: Pfizer, Abbvie, Lilly, Galapagos, BMS, Nordic Pharma, Sanofi, UCB, Grant/research support from: Pfizer, Abbvie, BMS, Nordic Pharma, Gebro, Roche, UCB, Victoria Navarro-Compán Speakers bureau: AbbVie, Eli Lilly, Janssen, MSD, Novartis, Pfizer, UCB Pharma, Consultant of: AbbVie, Eli Lilly, MSD, Novartis, Pfizer, UCB, Grant/research support from: AbbVie and Novartis.


This paper aims to present an output-input model initiated by the authors for evaluating the environmental impact of the typical road base materials on the cement granular soil,lime fly-ash granular soil and the industrial solid waste road base materials.As is known,the construction and the maintenance of the road base materials depleted large amount of natural rocks and cement materials,such as cement or lime,therefore,the road base material has a high impact on the environment,however,so far not enough attention has been paid to such impact.Therefore,the present authors have done a(catalogue) analysis and unitary analysis so as to assess the strength of the semi-rigid materials that may get contracting with the concrete.The results of our analysis indicate that the industrial solid waste road base materials had lower resource wastage,and their green house gas and acid rain gas and solid waste emission proves lower than concrete and other ordinary road base materials.The environmental impact of such industrial solid waste road base materials proves lower than the typical road base materials,such as cement stabilized granular soils.Such materials could be utilized as cement admixture so as to make them a whole serial of ecological building materials.


This research aims to explore how police officers responded to cyberstalking during the unprecedented period of the Covid-19 pandemic (March 2020–April 2021). More specifically, it aims to report the police experience of responding to cases of stalking, including cyberstalking, during this period; to explore officer confidence in identifying cyberstalking and to explore the challenges faced by frontline police. One hundred and two frontline police officers from two British forces took part in the online survey and, subsequently, ten officers and six key stakeholders each participated in a one-hour qualitative interview. The data indicate that the Covid-19 pandemic has prompted an increase in cyberstalking, and this has been attributed, by both the police and stakeholders, to the lockdown whereby people worked from home, had more time to become tech savvy and, as a result, developed digital skills that facilitate cyberstalking. Furthermore, it emerged that there is professional uncertainty among officers surrounding cyberstalking and how to deal with the problem effectively. However, this uncertainty is unquestionably not related to the lack of officers' motivation, but to absence of a stalking screening tool that addresses cyberstalking, accompanied by effective multiagency training that would assist officers to understand the nature of the issue and to respond to it effectively.


Simple Summary Oral and oropharyngeal cancers account for a worldwide incidence of 377,713 and 98,412 new cases annually and 177,757 and 48,143 deaths per year, respectively. Approximately 90% of oral malignancies are squamous cell carcinomas, showing a 5-year mortality rate still close to 50%. The poor prognosis of oral cancer is mainly related to its late diagnosis in advanced stages (stage III/IV), in which treatment is not effective. Therefore, reducing the delay in the diagnosis of oral cancer is an essential step in order to improve the outcomes and outlooks of patients affected by this disease. In this article, the diagnostic delay of oral patients is critically reviewed, jointly with their main reasons, difficulties, and future strategies for improvement. Abstract Oral and oropharyngeal cancers are a growing problem, accounting for 377,713 and 98,412 new cases per year all over the world and 177,757 and 48,143 deaths annually, respectively. Despite the substantial improvement in diagnostic procedures and treatment techniques in recent years, the mortality rate has not decreased substantially in the last 40 years, which is still close to 50% of cases. The major cause responsible for this high mortality is associated with the high percentage of oral cancers diagnosed in advanced stages (stages III and IV) where the treatment harbors poor efficacy, resulting in challenges, mutilations, or disability. The main reason for cancer to be diagnosed at an advanced stage is a diagnostic delay, so it is critical to reduce this delay in order to improve the prognosis of patients suffering from oral cancer. The causes of oral cancer diagnostic delay are complex and concern patients, healthcare professionals, and healthcare services. In this manuscript, oral cancer diagnostic delay is critically reviewed based on current evidence, as well as their major causes, main problems, and potential improvement strategies.


Many people would expect C to be of type matrix as well. Whether C is a matrix depends on the implementation of operator∗. In the case that the operator returns a matrix then C is a matrix. For the sake of performance, computationally expensive operators very often return an Expression Template and delay the evaluation to a later point in time when it can be performed more efficiently—because we know the entire expression and where the result is stored so that we can avoid the creation and destruction of a temporary. The impact of this approach to the beforementioned example is that C is not of type matrix but of some intermediate type that was probably only intended to be used internally in a library.


1. Project Goals The overall objective of this project is to improve the ruggedness, efficiency and power density of the single phase 7.2 kV, 20kVA Solid State Transformer (SST). To further increase the efficiency while attaining small size volume, Gen-III SST adopted a single stage AC-AC conversion techniques based on 15kV SiC devices. To our knowledge, this is the only known effort in the world on direct medium voltage AC-AC conversion. Bulk capacitance used in Gen-I and Gen-II are eliminated. Only two high voltage high frequency devices are required in the whole system. Comparing with Gen-II SST, the overall Gen-III AC-AC system attained a power density three times higher as shown in Fig. 1 (a). Fig. 1 (b) shows the efficiency curves of Gen-I, Gen-II and Gen-III SST. Gen-II obtains 97% efficiency at heavy load conditions, which is 2% higher than Gen-II.

Emotional labor, known as managed emotions, is exhibited in the face of communication with the service areas in order to adapt to the rules that the organizations have stated. The aim of emotional labor in this study is that organizations can be understood better in terms of employees. The literature survey for this purpose has provided emotional labor approaches, emotional labor dimensions, and the results of emotional labor. In the light of the obtained information; "Concept and concept of emotional labor" was interpreted in order to extract, evaluate, develop and correctly apply the first output in terms of a certain limited view in 1981, in a broader angle of 360 ° in modern business life. Thus, contemporary business organizations are expected to provide more humanitarian work conditions, realistic business relationships and a satisfying work environment, as well as increased productivity, quality, creativity and innovation.


A computational fluid dynamics (CFD) model is developed to simulate the dynamics of meniscus formation and capillary flow between vertical parallel plates. The arbitrary Lagrangian-Eulerian (ALE) approach was employed to predict and reconstruct the exact shape of the meniscus. The model was used to simulate the rise of water and the evolution of the meniscus in vertical channels with various spacing values of 0.5 mm, 0.7 mm, and 1 mm. The validity of the model was established by comparing the steady-state capillary height and the meniscus profile with analytical solutions. The developed model presents a novel approach for simulation of capillary flow accounting for the detailed hydrodynamic phenomena that cannot be captured by analytical models.


Background. Infants developing bronchopulmonary dysplasia (BPD) show decreased cortisol response to adrenocorticotropic hormone. A pilot study of low-dose hydrocortisone therapy for prophylaxis of early adrenal insufficiency showed improved survival without BPD at 36 weeks' postmenstrual age, particularly in infants exposed to histologic chorioamnionitis. Methods. Mechanically ventilated infants with birth weights of 500 to 999 g were enrolled into this multicenter, randomized, masked trial between 12 and 48 hours of life. Patients received placebo or hydrocortisone, 1 mg/kg per day for 12 days, then 0.5 mg/kg per day for 3 days. BPD at 36 weeks' postmenstrual age was defined clinically (receiving supplemental oxygen) and physiologically (supplemental oxygen required for O2 saturation >90%). Results. Patient enrollment was stopped at 360 patients because of an increase in spontaneous gastrointestinal perforation in the hydrocortisone-treated group. Survival without BPD was similar, defined clinically or physiologically, as were mortality, head circumference, and weight at 36 weeks. For patients exposed to histologic chorioamnionitis (n 149), hydrocortisone treatment significantly decreased mortality and increased survival without BPD, defined clinically or physiologically. After treatment, cortisol values and response to adrenocorticotropic hormone were similar between groups. Hydrocortisone-treated infants receiving indomethacin had more gastrointestinal perforations than placebo-treated infants receiving indomethacin, suggesting an interactive effect. Conclusions. Prophylaxis of early adrenal insufficiency did not improve survival without BPD in the overall study population; however, treatment of chorioamnionitis-exposed infants significantly decreased mortality and improved survival without BPD. Low-dose hydrocortisone therapy did not suppress adrenal function or compromise short-term growth. The combination of indomethacin and hydrocortisone should be avoided.

Relative adrenal insufficiency in the face of acute stress or illness is a well-recognized phenomenon.1,2 Affected individuals have apparently normal adrenal function under most circumstances but are unable to respond adequately to severe stress, displaying cardiovascular instability and increased mortality.1–3 A recent randomized trial showed that low-dose hydrocortisone therapy reduced mortality in adults with septic shock and relative adrenal insufficiency.4 Extremely premature infants may be at increased risk for a similar phenomenon during acute illness because of developmental immaturity of the hypothalamic-pituitary-adrenal axis. As reviewed by Mesiano and Jaffe,5 during much of gestation the fetal adrenal gland is deficient in the enzyme 3 -hydroxysteroid dehydrogenase (3 HSD), which catalyzes an essential step in the production of cortisol from cholesterol. After the embryonic period, the human fetal adrenal cortex probably does not produce cortisol de novo before 23 weeks of gestation, and in the undisturbed fetus may not do so until as late as 30 weeks of gestation. Instead, the fetus synthesizes cortisol from placental progesterone, bypassing the need for 3 HSD. After delivery, placental progesterone is no longer available, and limited 3 HSD may reduce the extremely premature infant's ability to produce cortisol when needed during illness.

Compared to the 5G network, the future 6G network is a multi-scenario application network containing more unattended terminals. The network slicing technology inherited from 5G enables more service providers to offer the same services with differentiated quality of services (QoS) and costs for their subscribers in 6G networks, in which more complex tasks occur for unattended terminals, such as unmanned factories, unmanned medical care, and unmanned rescues. However, network slice access of unattended terminals faces challenges. Specifically, physical attacks are a significant threat to unattended terminals in an open environment. The constrained resources and seamless services of unattended terminals also have to be considered. Unfortunately, there is currently a lack of an authentication scheme to address the above situation. As new lightweight hardware security primitive, Physical Unclonable Function (PUF) is an ideal solution to promote the security of unattended terminals. This article provides a specific authentication framework for unattended terminals in 6G-enabled network slices. Specifically, based on PUF, we first propose a physically secure slice access authentication protocol. Then we extend it to support fast inter-slice handover authentication, ensuring service continuity. Moreover, we prove the security of the proposed framework and conclude that it satisfies the higher security requirements of the 6G network. Finally, the performance evaluation with three other state-of-the-art authentication schemes demonstrates the superior efficiency of the proposed framework.


Abstract Electrophilic trisubstituted ethylene monomers, ring-substituted methyl 2-cyano-3-phenyl-2-propenoates, RC6H4CH=C(CN)CO2CH3 (where R is o-Cl, m-Cl, p-Cl, p-Br, and p-F) were prepared and copolymerized in solution with styrene at equimolar monomer feed composition in the presence of a radical initiator, AIBN at 80°C. The order of reactivity (1/r1) for the trisubstituted ethylene monomers was p-Cl (3.0) > m-Cl (2.9) > p-Br (2.3) > o-Cl (2.0) > p-F (1.4). High Tg's of the copolymers in comparison with that of polystyrene indicates substantial decrease in chain mobility of the copolymer due to high dipolar character of the trisubstituted monomer units.


Radio Frequency Identification Technology (RFID) has been explored for various process enhancements in clinical contexts, particularly hospitals, for asset tracking. The technology has been accepted in such environments, as it is inexpensive and, in principle, uncomplicated to integrate with other clinical support systems. It is perceived to offer many benefits to currently resource critical/strained clinical environments. This research investigation focuses on the exploitation of the potential of the technology, to enhance processes in clinical environments. In this paper, the researchers aimed to uncover if the technology, as presently deployed, has been able to achieve its potential and, in particular, if it has been fully integrated into processes in a way that maximises the benefits that were perceived. This research is part of a larger investigation that aims to develop a meta-model for integration of RFID into processes in a form that will maximise benefits that may be achievable in clinical environments. As the first phase of the investigation, the key learning from a clinical context (hospital), which has deployed RFID and attempted to integrate it into the processes, to enable better efficiencies, is presented in this paper. The case method has been used as a methodological framework. Two clinical contexts (hospitals) are involved in the larger project, which constitutes two phases. In Phase 1, semi structured interviews were conducted with a selected number of participants involved with the RFID deployment project, before and after, in clinical context 1 (hereinafter named as CC1). The results were then synthesised drawing a set of key learning, from different viewpoints (implementers and users), as reported in this paper. These results outline a linear conduit for a new proposed implementation (CC2). On completion of the phase II, the researchers aim to construct a meta-model for maximising the potential of RFID in clinical contexts. This paper is limited to the first phase that aims to draw key learning to inform the linear conduit.

In data grid, how to access data is the key problem of application metadata management and replica metadata management. To resolve the problem, this paper proposes a metadata classified management mechanism(MCMM for short) based on data grid that defines a data model and an application metadata schema and applies different storage methods to different metadata, and MCMM designs a guide\|based query intelligence entity.


The aim of the present study was to investigate the influence of social factors on literacy of 9 years-old primary school children. The independent variables were: sex, education of father and mother, profession of mother and father, family size and birth order. The sample of the study consisted of 89 primary school pupils aged from 8.03 to 9.04 years old, from four schools of Volos and Patras. Assessment instruments included a reading comprehension test, a reading accuracy test, a vocabulary test, Raven -CPM test and six subtests of literacy skills derived from the Athena Test (Sentence completion, Word Completion, Sound Synthesis, Sound Discrimination, Letter Discrimination and Verbal Analogies). Factor Analysis of the ten dependent variables revealed one factor called "language-reading ability". Multiple Regression Analysis indicated that the independent variables predicted pupils' attainments on "language-reading ability" (p = .007). Limitations and implications of the study are critically discussed.


ABSTRACT Under the dominant role of a belief function, Farmer argues that the stock market is the Granger cause of the unemployment rate, which implies that the natural rate hypothesis is an outdated idea. This article provides some new empirical evidence supporting this view using threshold cointegration and asymmetric error correction models. The results show that these models can assess asymmetric dynamics between unemployment and the stock market. Moreover, regime switches of the momentum threshold autoregressive adjustment specification are highly consistent with recessions in the US economy during the last 60 years.


A formal approach can benefit multimedia in a number of ways. For example, formal system development can aid the development of correct systems. Formal specification and verification techniques have been extensively investigated, but these techniques have generally not addressed the requirement of distributed multimedia computing. The central issue in multimedia is dealing with real-time. In particular, there is a need for software development techniques that support the specification and verification of real-time properties. In this paper, we propose a new approach to the formal specification and verification of distributed multimedia computing. This new approach is based on the extension of LOTOS to incorporate timing in it. Thus, succinct expressions of communicating concurrent processes can be made. Similarly, the emphasis on non-determinism in process algebraic techniques facilitates abstract specification, hiding implementation details. Furthermore, rich and tractable mathematical models of the semantics of process algebra have been developed. The key characteristic of the new approach lies in the specification of behavior, requirements and different types of time in a specification.


BACKGROUND: Olive oil mill waste is a serious environmental problem in the Mediterranean basin given its particular characteristics of high organic content, seasonal and localized generation, and the type of processing involved. RESULTS: Olive mill waste from a three-phase mill was characterized by means of total analysis, availability and mobility of the pollutants in order to help the decision-maker about possible options for its valorization and/or disposal. Water content, loss of ignition, total organic carbon, phenol index and metals concentrations were measured to fully characterize the waste. Three leaching tests (NEN 7341, EN 12457 and UNE CEN-TS 15364 EX) were carried out to evaluate the environmental hazard of the waste material and the leachates were characterized with respect to electric conductivity, pH, heavy metals, anions and organic pollutants (phenol index and total organic carbon) according to European waste directives. The results were compared with EU regulations for inert, non-hazardous and hazardous waste disposal. CONCLUSION: It was found that not only organic parameters must be taken into account concerning the fate of this waste material, but also the mobility of heavy metals and anions should be studied. Furthermore, stabilization/solidification processes are recommended before landfill disposal of this kind of agro-waste material. c � 2011 Society of Chemical Industry

Abstract The enzymes trypsin and urease were covalently tethered to cellulose to utilize their ability to produce colored products as a consequence of enzymatic activity. Therefore, cellulose had to be chemically modified first in order to generate appropriate chemical functionalities. Different approaches including periodate supported oxidation followed by immobilization via reductive amination, insertion of a reactive polymer interface, and cross-linking inside the cellulose matrix were utilized for the immobilization. The success of immobilization was assessed by the quantification of surface-bound protein as well as by recording of enzymatic activities under different conditions. The enzymatic activity of trypsin and urease was maintained best when a hydrophilic intermediate polymer layer was used for immobilization. The applicability of immobilized enzymes as temperature indicators was demonstrated using cross-linked urease.

Most judges have no more medical expertise than the average intelligent lay person. It is for this reason that we rely heavily on expert opinion. In family proceedings, the evidence given by a medical expert can play a large part in determining the future of a child. In the criminal courts it can be the deciding factor in conviction of a parent or other member of the family for injuring or killing a child.


This article reports on a study of double-objective detection, proposed for a driver's alert level. The method, based on the single-objective detection, includes the states and changes of both eyes and mouth of a driver that are taken as the drowsy discriminance of a driver's fatigue through his or her entire facial image when traveling. The characteristic vectors of both the eyes and lip of a driver are sequentially input into a modified BP network. Then, the region matching algorithm is introduced to detect comprehensively the alert level of a driver in accordance to the quantified evaluation indices showing how much fatigue the driver is feeling. The authors used VC++ to develop an algorithm software to monitor driver's fatigue, then use it to carry out a simulation test. They conclude, based on the test results, that the double-objective detection system can monitor and accurately identify a driver's alert level.

The paper is focused on turning of structural steels C45. Cutting tools were represented by carbide cutting inserts without coatings, with reference coating TiAlN, as well as with multilayered composite nano-structured coatings Ti-TiN-(TiCrAl)N and Zr-ZrN-(ZrCrNbAl)N (of different thickness of 3-7 μm). The following studies of the properties of coated tools were carried out: measurement of microhardness and strength of adhesion bonds in the "tool-coating" system and investigation of elemental and phase compositions of coatings. The cutting tests were carried out at the following cutting modes: f = 0.2 mm/rev; аp = 1.0 mm; vc = 200, 250, 300, 350 and 400 m/min.


We have developed a highly efficient new method for the introduction of Lewis acidic boron centers into the side chains of organic polymers. Our methodology involves three steps:  (i) the controlled polymerization of the functional monomer 4-trimethylsilylstyrene (S−Si), (ii) the exchange of the silyl groups in poly(4-trimethylsilylstyrene) (PS−Si) with BBr3 to give the reactive polymer poly(4-dibromoborylstyrene) (PS−BBr), and (iii) the fine-tuning of the Lewis acidity of the individual boron centers through substituent exchange reactions with nucleophiles. Treatment of PS−BBr with ethoxytrimethylsilane and THF respectively yields the moderately Lewis acidic poly(arylboronate)s PS−BOR (R = Et, 4-bromobutyl). The alkoxy groups in PS−BOR have been exchanged with pinacol to form the air-stable polymer PS−BPin (Pin = pinacolato). Treatment of PS−BBr with 2-thienyltrimethyltin and pentafluorophenylcopper respectively gives the well-defined highly Lewis acidic triarylborane polymers PS−BTh and PS−BPf (Th = 2-t...
