Role of residual stresses in the evaluation of SCC susceptibility of welded joints was studied on the butt-welded stainless steel specimens. Distribution of residual stresses was measured by both nondestructive X-ray method and modified Kelsey's method which was newly proposed for the determination of residual stresses within the specimens. Comparison of data accuracy and measuring facilities in both methods was made and resulted that modified Kelsey's method was an available one. Threshold residual tensile stress which causes SCC without applied stresses was found to be 11kg/mm2 in the combination of austenitic stainless steel SUS 304-42% boiling magnesium chloride solution. However, in some cases, cracks initiated at the place with surface residual stresses lower than the threshold residual stress, therefore materials properties, such as pre-strain (defect concentration), surface roughness and residual stresses within the specimen also should be taken into account as well as the surface residual stresses. For the evaluation of SCC susceptibility in the test case where applied stresses were imposed on the specimens with residual stresses. Resultant stress composed of applied and residual stress at crack initiation was proposed and found to be an effective parameter in most cases of all specimens tested. But this parameter also becomes improper one for the estimation of SCC susceptibility, especially in the case of specimens which have both hardened surface and therefore higher residual stresses than the original yield strength. Shot peened and ground specimens are this case. The reason for this inconvenience and other troubling cases in using resultant stress are discussed based on the materials properties of specimens.


In this paper we describe a research-practice partnership between the Woolf Fisher Research Centre and the Digital Schools Partnership, a group of 84 schools in 11 geographically-based clusters that were implementing a ubiquitous digital teaching and learning platform within their face-to-face classes. The model of research-partnership employed is the Learning Schools Model (LSM), which is a design-based research approach that has been tested and replicated over 15 years and across diverse contexts and countries. We reflect on benefits and challenges of working in partnerships to achieve practice and research aims, which are to improve valued learning outcomes for students historically under-served in education and to advance research knowledge more generally (Lai, McNaughton, Jesson, & Wilson, 2020). We describe a recursive process of collective inquiry that involves researchers and teachers: working together to identify valued learning outcomes (VLOs) on which to focus our improvement efforts; developing a rich profile of students' strengths and areas for improvement with respect to those VLOs; generating and testing a set of possible explanations for that profile of learning; co-designing and implementing targeted interventions, and; evaluating the extent and  impact of changed practices. We reflect on the importance of building relational trust and approaches for doing so.


Advanced undergraduate experiments utilizing a commerically available, thin 252Cf spontaneous fission (SF) source are described. These include studies of the energy and mass distribution of the fission fragments and their energy and angular correlation. The energy loss of heavy ions traversing solid and gas absorbers is measured and their effective charges deduced. The SF rate relative to the alpha decay rate is used to infer the SF half‐life. These experiments provide a useful introduction to fission, nuclear mass equations, heavy‐ion physics, and related topics.


By the New East—Asia Theory,the East Asian Development Model that has ever created the East Asian Miracle is a kind of special innovation system,and there is no time—invariant development model at any age. The East Asian Financial Crisis is directly caused by the changes of international economic conditions,at the same time,it also resulted from the lag adjustment of the East Asian development model. From the theory as is stated above,by rethinking the development process of Taiwan Economy in recent 60 years,it can be found that being the fundamental components of the East Asian Innovation System,export orientation and government role have been important from the beginning to end. Simply because of the Taiwan authorities' having not made corresponding adjustments and changes,even conducting reversely,Taiwan economy resulted in changing from the Miracle to the Dilemma.


Genetic deletions of IKZF1 are associated with poor prognosis in B-cell acute lymphoblastic leukemia (B-ALL). Here we investigated the effect of IKZF1 deletions (IKZF1 del) plus with immunotype in adult B-ALL in PDT-ALL-2016 cohort. This cohort study involved 161 patients with B-ALL from 2016 to 2019, with detailed information about IKZF1 del and CD20 expression. Validation cohort consists N= patients from TARGET cohort. IKZF1 del was detected in 36.0% of patients with 3-year event-free survival (EFS) of 37.2±6.7% and overall survival (OS) of 51.1±7.3%, compared to IKZF1 wild-type (IKZF1 wt) with EFS 55.4±5.1% (P<0.01) and OS 74.6±4.5% (P<0.05), respectively. CD20 expression was also associated with inferior EFS than CD20-negative group (P<0.05). Furthermore, IKZF1 del coupled with CD20 expression, termed as IKZF1 del/CD20+, comprised 12.4% of patients with 3-year EFS of 25.0±9.7% compared with IKZF1 wt (P<0.05 ) and IKZF1 del/CD20- (P<0.05 ) groups, respectively. Multivariable analyses demonstrated independence of IKZF1 del/CD20+ with highest hazard ratio for EFS and OS. Furthermore, the prognostic strength of IKZF1 del/CD20+ was confirmed in TARGET validation cohort. Eighty-one patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT). Notably, neither IKZF1 del(P=0.6288), CD20 (P=0.0705) or IKZF1 del/CD20 (P=0.3410) groups were identified as poor outcome in allo-HSCT cohort. Collectively, our data demonstrate that IKZF1 del/CD20+ represents a very high-risk subtype in adult B-ALL; and particularly, allo-HSCT could overcome the poor outcome of IKZF1 del and IKZF1 del/CD20+.

2CH3. CO.COOH + H20CH3. CHOH. COOH + CH3.COOH + CO2. (2) Hills [1938] found that this dismutation depends on the presence of vitamin B1. In organisms grown on vitamin-deficient media the rate of dismutation is much reduced, and addition of vitamin B1 restores the rate to its normal level. How reaction (1) is related to the dismutation of pyruvate is not at first sight obvious, but if it is assumed (a) that oxaloacetate acts as a carrier in reaction (2), (b) that oxaloacetate is formed by reaction (1), then the action of vitamin B1 in Staphylococcus can be explained in the same way as in pigeon liver. The results described here are in agreement with assumptions (a) and (b) and support the view that in Staphylococcus, as in pigeon liver, vitamin B1 catalyses the synthesis of oxaloacetate from pyruvate and CO2.


The parameter of ionosphere that produces most of the effects on radio signals is total electron content (TEC). Ionospheric TEC variation with time can be viewed as a stationary random process under quiet conditions. This paper investigate the TEC covering the period from 8 November 2005 using Malaysia data for KTPK station. During this period with Kp, Dst, and Ap indices values of reported by the World Data Center (WDC). This research using two technique which is TEC dual frequency and TEC Map. For TEC dual frequency, carrier-phase and code-delay GPS observations are combined to obtain ionospheric observables related to the slant TEC (TECs) along the satellite-receiver line of sight (los). Whereas for TEC Map technique, GPS measurements from KTPK stations at Malaysia region were used for producing maps. The Bernese GPS software version 5.0 was used to derive TEC from GPS data. Through BGS's Bernese Processing Engine (BPE)'s PPP mode, GPSEST program is used to model and estimate the ionosphere. The result show that for TEC dual frequency this results in the absolute differential delay and the remaining noise was discarded whereas for TEC Map technique show the TEC measurements with a high temporal and spatial resolutions.


Introduction . Citrus canker, caused by the bacterium Xanthomonas axonopodis pv. citri, is a serious disease of most commercial citrus cultivars and some citrus relatives. Surveys were conducted in small-scale farms, commercial plantations, backyard orchards and nurseries in order to quantitatively study the occurrence and distribution of the disease and determine the intensity and field host range. Materials and methods . Seventeen locations in four regional states of Ethiopia were surveyed. Incidence on leaves was determined by counting total number of leaves and expressed as a proportion of leaves with at least one lesion. Incidence on fruits was determined on attached fruits, recorded as presence or absence of the symptoms. Severity was also measured on leaves and fruits. The identity of the pathogen was confirmed by morphological, biochemical and physiological characterization and detached leaf tests of representative isolates. Results . The surveys indicated the occurrence of citrus canker in Ethiopia. Overall incidence on leaves was 71.4% of leaves with at least one lesion and severity was 26.8% of leaf area infected. Incidence on fruits was 30% of fruits infected and severity was 21.25% fruit area infected. Morphological, biochemical and physiological characterization and detached leaf tests of isolates indicated characteristics similar to X. axonopodis pv. citri. The host range for citrus canker in Ethiopia was limited to Mexican lime (C. aurantifolia ) and sour orange (C. aurantium ). Based on the field host range and detached leaf tests, it appears that the X. axonopodis pv. citri variant that occurs in Ethiopia has similar host ranges to that of atypical Asiatic (Xac -A*) form. Canker severity significantly correlated with temperature but not with rainfall, elevation or tree age. Conclusion . This is the first confirmed report of the disease in Ethiopia.


The $C^*$-algebraic $\kappa$-Poincar\'{e} Group is constructed. The construction uses groupoid algebras of differential groupoids associated to Lie group decomposition. It turns out the underlying $C^*$-algebra is the same as for "$\kappa$-Euclidean Group" but a comultiplication is twisted by some unitary multiplier. Generators and commutation relations among them are presented.


Measurement data cleaning is a key step of edge computing in a distribution network; it is beneficial to improve the state perception and regional autonomy level of a distribution network. According to the temporal and spatial correlation of measurement data in the distribution network, a joint cleaning method of measurement data in a distribution network is proposed based on the correntropy criterion with variable center unscented Kalman filter (CC-VC-UKF). Initially, the mean square error (MSE) in the original unscented Kalman filter (UKF) is replaced by the correntropy criterion with variable center (CC-VC) to improve the accuracy of filtering the measurement data in the distribution network with a non-Gaussian non-zero mean measurement deviation. Then, the measured data of different measuring devices located on the same section of the line are filtered based on the CC-VC-UKF algorithm according to their respective reference time series to improve the signal-to-noise ratio of the measured data. Then, the filtered measured data are filtered and cleaned based on the CC-VC-UKF algorithm according to the space–time joint filtering and cleaning technology. Finally, the method is used to test the measurement data of the distribution network obtained by a power supply company in a city in north China to solve the problem of measurement deviation caused by the existence of space distance. Results show that this method can obtain FTU measurement data with higher precision from network topology based on the filtered TTU measurement data through the media of filtered spatial measurement deviation.

A series of tetranuclear metal complexes of grid-type consisting of four bis-tridentate ligands and four divalent transition metal ions were synthesized and characterized. The 1H NMR spectra of diamagnetic complexes containing Zn(II), Cd(II), Fe(II), and Ru(II) was correlated to the radius of the metal ion. The UV–vis and electrochemical results indicated that the bridging ligand π* orbital and the dπ metal orbital are stabilized by complexation of more than one metal ion. Furthermore, the Co(II) and Fe(II) grids exhibit metal–metal interaction mediated by the bis-tridentate ligands as indicated by electrochemical and spectroscopic methods. These results provide guidelines for the design of larger grids bearing several metal centres in a square arrangement, which also represent potential components of molecular electronic devices.Key words: complexes with nitrogen ligands, octahedral metal ions, self-assembly, supramolecular chemistry.


Over the last twenty-five years, there has been a lot of interest in herd behavior in financial markets?that is, a trader?s decision to disregard her private information to follow the behavior of the crowd. A large theoretical literature has identified abstract mechanisms through which herding can arise, even in a world where people are fully rational. Until now, however, the empirical work on herding has been completely disconnected from this theoretical analysis; it simply looked for statistical evidence of trade clustering and, when that evidence was present, interpreted the clustering as herd behavior. However, since decision clustering may be the result of something other than herding?such as the common reaction to public announcements?the existing empirical literature cannot distinguish ?spurious? herding from ?true? herd behavior.


The present paper intends to demonstrate, on the other hand, as the growth of the economy can be led by the exportations and, for another one, as such growth can have a external restriction of financial order for countries that present a deficit structural rigidity in the relation of commerce with the remaining portion of the world. Front to such situation, will be presented two alternatives: or the country increases the rate of interests to keep the flow of capital, becoming, however, the dimension of the unsustainable external liabilities; or the country carries through a structural change in the economy that favors the product quality exported or reduces the technological gap in relation to the remaining portion of the world.

One of the pioneer and important fields in the computer science area is cloud computing. The data within cloud computing are usually transformed to it from local storage; therefore, the security of this data is an important issue. To solve this data security issue, it is important that cloud service providers (CSPs) store encrypted versions of user data. Before transmitting data to the cloud provider, it was encrypted using traditional encryption schemes. Nevertheless, for these schemes, the private key must be provided to the server to be used for the decryption on the other side before any calculations, yielding a security risk and issue for the cloud data. Homomorphic encryption provides a capable solution to this issue since it enables calculations on encrypted data with no need to be decrypted and the private encryption key is not compromised. A new fully homomorphic encryption scheme to protect cloud data is proposed in this paper, it is called NAZUZ. The NAZUZ scheme is based on prime modular operations and encrypts messages by operating on each character without converting them to binary. NAZUZ security relies on the difficulty of factoring large integer numbers and introduces noise complexity to the plaintext through the number of CSP users.


Alzheimer's Disease (AD) ravages the cognitive ability of more than 5 million Americans and creates an enormous strain on the health care system. This paper proposes a machine learning predictive model for AD development without medical imaging and with fewer clinical visits and tests, in hopes of earlier and cheaper diagnoses. That earlier diagnoses could be critical in the effectiveness of any drug or medical treatment to cure this disease. Our model is trained and validated using demographic, biomarker and cognitive test data from two prominent research studies: Alzheimer's Disease Neuroimaging Initiative (ADNI) and Australian Imaging, Biomarker Lifestyle Flagship Study of Aging (AIBL). We systematically explore different machine learning models, pre-processing methods and feature selection techniques. The most performant model demonstrates greater than 90% accuracy and recall in predicting AD, and the results generalize across sub-studies of ADNI and to the independent AIBL study. We also demonstrate that these results are robust to reducing the number of clinical visits or tests per visit. Using a metaclassification algorithm and longitudinal data analysis we are able to produce a "lean" diagnostic protocol with only 3 tests and 4 clinical visits that can predict Alzheimer's development with 87% accuracy and 79% recall. This novel work can be adapted into a practical early diagnostic tool for predicting the development of Alzheimer's that maximizes accuracy while minimizing the number of necessary diagnostic tests and clinical visits.


The steam line break accident for Kori Unit 1 is analyzed by a code SYSRAN which calculates nuclear power and heat flux using the point kinetics equation and the lumped-parameter model and calculates system transient using the mass and energy balance equation with the assumption of uniform reactor coolant system pressure. The 1.4 f steam line break accident is analyzed at EOL (End of Life), hot shutdown condition in which case the accident would be most severe. The steam discharge rate is assumed to follow the Moody critical flow model. The results reveal the peak heat flux of 38% of nominal full power value at 60 second after the accident initiates, which is higher than the FSAR result of 26%. Trends for the transient are in good agreement with FSAR results. A sensitivity study shows that this accident is most sensitive to the moderator density coefficient and the lower plenum mixing factor. The DNBR calculation under the assumption of =3.66, which is used in the FSAR with all the control and the shutdown assemblies inserted except one B bank assembly and of Fz=1.55 shows that minimum DNBR reaches 1.62 at 60 second, indicating that the fuel failure is not anticipated to occur. The point kinetics equation, the lumped-parameter model and the system transient model which uses the mass and energy balance equation are verified to be effective to follow the system transient phenomena of the nuclear power plants.lear power plants.


The Stark representation of the resonator field and the first order of perturbation theory of the fluorescence field are used to study the fluorescence spectrum of one and two two-level atoms in an ideal resonator as a function of the initial excitation of the system. It is shown that in the absence of resonator photons (nc = 0) the spectrum obtained for initial excitation of one atom consists of two lines located symmetrically relative to the central frequency ωα. In all other cases the spectrum consists of the central harmonic ωα and of ωα ± 2Ω satellites (Ω is the Rabi frequency). The intensity of collective higher harmonics ωα ± 4Ω is low and it falls on increase in the resonator field as I/nc2. The nonlinearity of the interaction Hamiltonian results in parametric amplification of the ωα + 2Ω harmonics and in attenuation of the ωα–2Ω harmonics. In the case of two atoms it is possible to achieve stimulated fluorescence at the harmonics ωα ± 2Ω.


Production of satellites in the United States has largely converged on a business model which focuses on large, highly capable units, engineered for exquisite performance, high mission assurance and long lifespans. As the capability of nanosatellite components matures, opportunities emerge to exploit these new technologies to develop disaggregated tactical support systems for the warfighter which would be low cost, survivable and responsive to individual needs. Raytheon, in concert with other vendors and the Defense Advanced Research Projects Agency (DARPA), has brought into existence automated production facilities designed for this purpose, which maintain the capability to produce nanosatellites such as SeeMe and Phoenix satlets concurrently. The development of this manufacturing capability permits short term production runs of satellites as needed with a fraction of the cost of a dedicated production line. Detailed work flows derived from robotic work instructions provide a sound basis for assembly simulations, establishing confidence in unit price and schedule. A detailed account of this automated assembly line, along with current expansion plans is discussed, providing insight into future production capabilities.

Recent research finds that consumers pay more and more attention to the high grade product. An intelligent decision making system is proposed in this paper, the purpose of which is to monitor product quality of manufacturing system and give warnings to the quality managers accordingly. Since the complex interaction among the multivariate quality characteristic (QC) and the intelligent model is hard to be manually managed, the well-performing machine learning algorithms need to be proposed to support an automatic control of product quality. And many decision making tools have been developed to monitor product quality with the intelligent control model. Fuzzy cognitive map (FCM) is a popular tool for intelligent modeling, and is usually applied to many fields. In this paper, FCM is used for intelligent modeling in the decision making process of manufacturing system. Based on the mechanism, we design an intelligent model to solve the decision making problem of product quality control. Then, the effect of varying the support scale of trained data is tested by using FCM in different environments. Finally, we get some useful conclusions and discuss several potential research developments in the future.


This paper focuses on a novel energy management strategy for aeronautical electrical networks, including supercapacitors for fast energy charge/discharge cycles. Considering a simplified but representative architecture for a DC aeronautical electrical network, the bidirectional DC/DC converter equipment acts as a bridge between the HVDC network and the LVDC network, operating in Buck or Boost with respect to the current flight conditions and flight phase. The main idea of the paper is to let the DC/DC converter, connected between the DC bus and the supercap, being supervised in order to autonomously decide the conversion mode (i.e. Buck or Boost), in order to cope with generator overloads and reduce its overload capacity, hence its dimensions. The supervision is based on sliding mode for the converter control, whose stability proofs are given. Simulation results are shown in order to give evidence about the effectiveness of the proposed approach.


Abstract. In situ investigations of growth and production in a stand of Posidonia oceanica (L.) DELILE at a depth of 4 m at Ischia (Gulf of Naples) were carried out over two growing seasons. Posidonia starts to grow in August and an average bundle produces ten leaves in increasing time intervals until May. Growth curves for the leaves are given. Maximum leaf standing crop is in May with 1300 g dry weight per m-2, leaf area index at this time reaches 22 m2 m-2. Leaf net productivity is highest in March with 12 g dry weight per m2 per day. Annual leaf production is estimated as 3110 g dry weight per m2, "underground" production as 115 g dry weight per m2. About half the leaf production is exported from the system. Adaptive strategies of the growth and production pattern are discussed.


This paper discusses a program designed to assist counseling students to improve cross cultural communication skills that will enable them to use interviewing techniques with individuals from diverse cultures. Research suggests that such a program is needed since many students have not had significant experiences in interacting and communicating with people from different backgrounds. The program offers an open-ended approach with continual opportunities to refine and enhance skills of students, building on the demonstration videos of previous students. The structured interview process described offers an integrative, flexible, and developmental model for enhancing cross cultural communication. The model offers the possibility of involving counselors in training at all levels of experiences. (Contains 12 references.)

In this paper, we present a novel color image Demosaicking algorithm. The algorithm consists of two steps: an interpolation step and a refinement step. The missing green color information is first interpolated by using the color channel difference. In the refinement step, a local weighted directional interpolation method guided by the preinterpolated green channel is applied to refine the interpolation results along the determined interpolation direction. Lastly, post-processing is implemented to output the final Demosaicked full color image. Compared with the latest Demosaicking algorithms, experiments showed that the proposed method provides superior performance in terms of both objective and subjective image qualities.

In view of the significance of albumin degradation products in relation to beer foam and palate fullness, and the apparent localization of amylase in the albumin fraction of barley, it appears desirable to develop means for accurate determination of barley amylase, including both free and total amylase. A suitable method for this purpose involves extraction of barley meal with 0.1 M sodium chloride solution for free amylase determination and by sodium chloride in presence of cystein for total amylase, it having been shown that the inactive enzyme is activated by reducing substances; the effect is probably independent of any influence on proteolytic enzymes. Further, proteinase activity in barley can be determined by a modification of the Anson method, using haemoglobin as substrate, and determining proteolysis either spectrophotometrically or by applying Kjeldahl's method to the soluble products formed.


Monte Carlo simulations of three-state Potts models interacting with nearest-neighbor antiferromagnetic J 1 ( 0) are carried out on a square lattice. At enough low temperatures an antiferromagnetic ordering is shown to appear except for J 2 =0. In the intermediate temperatures the occurrence of the Kosterlitz-Thouless-like phase is indicated from the estimation of the critical exponent η.


Virtually all the agents now available for the treatment of infections were discovered by chance, or at best developed without a specific plan rather than on the basis of a sequence of logical experiments. An element of reason went into the original decision to screen samples of soil for the presence of microorganisms (usually molds) capable of producing antibiotic substances, but thereafter the procedures used were, of necessity, entirely empirical. Although there are notable exceptions, such as hexamine, mandelic acid, nalidixic acid, the nitrofurans, sulfonamides, p-aminosalicylate, and isoniazid, nearly all the clinically useful antibacterial compounds such as the (3-lactam compounds, aminoglycosides, tetracyclines, and macrolides were developed by observation and experiment without any background theory. Admittedly, some of the more sophisticated refinements have been planned by chemical methods, and the introduction of the semisynthetic penicillins and cephalosporins was a major advance in antimicrobial therapy. Nevertheless, empiricism was inevitable, and history has shown that the mode of action of an antibacterial compound is rarely known until some time after its introduction into clinical practice. The best example is penicillin. The explanation for selective toxicity of penicillin was not known until more than 20 years after its discovery, and the method of transport of wall components by lipid intermediates in the membrane remains to be elucidated.

Significant thermal effects on in vitro protein quality of red kidney beans were observed. Beans autoclaved at 121 o C for 10 and 20 min, and common home-cooked beans had improved protein quality. Uncooked beans, and those autoclaved at 128 o C for 20 min and at 121 o C for 90 min had reduced protein quality compared to canned beans and those autoclaved at 110 o C for 20 min and at 121 o C for 40 and 60 min. Amino acid scores, essential amino acid index and available lysine (%), corrected for in vitro protein digestibility gave comparable results in evaluation of protein quality. Specific lysine, methionine, cysteine and other amino acid ratios overestimated protein quality


—There are three histological layers within the rat olfactory tubercle: plexiform, pyramidal and polymorphic. We have assayed glutamic acid decarboxylase (GAD) and GABA in homogenates of frozen sections cut parallel to these layers. Consecutive sections (16 μm) were homogenized in groups and assayed for GAD or GABA. Every seventh section was stained with Toluidine Blue to monitor the depth and orientation of the plane of section. Steep variations in GAD activity (up to 6‐fold) were observed as a function of depth in the tubercle. These were paralleled by corresponding but less marked variations in GABA levels. The lowest values were found in the plexiform layer. This suggests that GAD may play a very limited role there. The highest activities were found in sections from the deepest lamina of the polymorphic layer. This is the only lamina of the tubercle that does not receive a dopaminergic input.


Basing on the fruit trees' phonological observation data from 1998 to 2010 and meteorological data from1981 to 2010 in main planting regions in the dryland area of southeast Gansu,the model of water suitability for fruit trees growing was set up with the FAO Penman-Monteith formula( 1998 edition) and crop coefficient,the water requirement of fruit trees in different growth periods from 1981 to 2010 was calculated. The results showed that the drought in spring appeared more and more severe compared with other seasons during the period of fruit growing since 1980 s. The water suitability of whole growth periods decreased with the time under the background of climate warming,the water supply to apple and grape was under good conditions,which annual mean water suitability was above 0. 50; the water supply to big cherry and peach was under bad conditions,which annual mean water suitability was 0. 41 and 0. 47,respectively. The water suitability for 4 kinds of fruit trees decreased at the initial growth stage. The grape was with an optimal moisture condition,followed by apple. The water suitability of big cherry and peach was less than 0. 40 since 2010 s,and the contradiction was marked between supply and demand of water during initial growing of big cherry. The water suitability of grape and apple increased at the vigorous growth stage since 2010 s. The amount of water requirement for peach and big cherry in fruit trees growing was lacking,and the water suitability of big cherry was only 0. 31,with increased water stress because of the spring drought. The water suitability increased basically at the last growth stage,and the precipitation was more than the amount of water requirement for grape with the water suitability of above 1. 0,1. 0 for apple. The precipitation was suitable for apple;it was above 0. 5 for big cherry and peach. The precipitation could also satisfy requirement. The established model can assess the environmental climate of fruit trees and provide scientific suggestion for planting regions of fruit trees in the dryland area of southeast Gansu.


T1-201 and I-131 scintigraphy were performed to visualize malignant lesions postoperatively in 26 patients with well-differentiated thyroid cancer. Anyone of uptake index and retention index was higher in malignant lesions than that in benign lesions. T1-201 scintigraphy showed uptake ininflammatory tissues. T1-201 concentration was observed in fourteen patients and six of them had malignant lesions, while I-131 concentration was observed in six patients and all had malignant lesions. In sensitivity, combination of T1-201 and I-131 scintigraphy is higher than I-131 or T1-201 scintigraphy only. In postoperative patients with well-differentiated thyroid cancer, it may be useful that T1-201 scintigraphy will be performed simultaneously with I-131 scintigraphy for detecting recurrence.

A p-value <.05 was considered as statistically significant Findings: During this study, a total of 250 positive blood cultures were reported for infants less than 3 days old. Of these, 21(8.4%) E. coli strains were isolated from 14 preterm and 7 term neonates. In all patients, the most effective antibiotic was meropenem, and the highest resistance was observed to cefoxitin. Conclusion: Base on the present study results, E. coli is the most prevalent Gram-negative bacterium isolated in Shiraz. Premature birth and very low weight are the most important risk factors for developing early-onset sepsis. Copyright© 2021, TMU Press.

A voltage regulator (2) controls an output of an automobile alternator (1) by controlling an intensity of the excitation current supplied to the alternator excitation winding (102). The intensity of the excitation current is detected by a detection resistor (203) as the detected voltage appearing across the detection resistor. The detected voltage is amplified by an amplifier (501, 502, 503) to obtain a detected voltage (Vd), whose amplification coefficient is adjusted on the basis of a reference voltage (Vr) corresponding precisely to the intensity of the excitation current and, consequently, the detected voltage (Vd) is made equal to the reference voltage (Vr). In this way, the excitation current is accurately detected without mechanically adjusting an ohmic value of the detection resistor (203) for functional adjustment or the like.


Transistor Laser (TL) has multiple modulation methods by a combination of terminal connection because it has three electrical terminals unlike the laser diodes. In this report, for the voltage modulation of the TL, the light output response under a large signal voltage modulation was simulated. By considering the transient change of the current in the active layer, we succeeded in reproducing the light output having the peak in the opposite direction to the steady state observed with the actual device so far. Based on the simulation, the optimum collector-base capacitance in the actual device and the minimum required end-facet reflectance for securing a high extinction ratio were obtained.


With the development of fingerprinting-based visual localization technology, a problem with this method is standing out, which is it takes great expenses in fingerprint collection. Recently, a few studies proposed some methods to alleviate this problem. However, the accuracy of the existing method is relatively low under some scenarios such as wide field of vision. In this paper, we propose a novel automatic visual fingerprinting (AVF) method for an indoor visual localization system. We consider the performance of AVF greatly hinges on visual odometry (VO) and ego-motion estimation (EME) block, which are two different ways of estimating fingerprint coordinates. Since both visual odometry and ego-motion estimation model are inaccurate, we build the least square model by second-order cone programming (SOCP). Our SOCP-based method is proposed to deal with the serious cumulative error and the random error introduced by VO and EME model, respectively. The purpose of this paper is improving the accuracy of the database generated by the AVF method under wide field of vision scenarios. Although the time costs are relatively higher than our compared method, fortunately, it is only on the off-line stage. The simulation results show that our method can provide a reliable image-location database with the consumer-grade smartphone camera.


In the framework of eiconal approximation and the double folding model, a formalism for calculating inclusive spectra of particles from stripping and fragmentation reactions involving light cluster nuclei is proposed. The cross-section of the 12C(3He, d)13N reaction at an incident particle energy of 81.4 MeV and the proton spectra from the deuteron fragmentation reaction with 56 MeV energies by 12C and 27Al nuclei are described. The calculated values satisfactorily fit the corresponding experimental data.


This study applies Amartya Sen's cooperative conflict model as a tool to examine gender relations in the household, which in turn determine women's participation in the market and their bargaining position. The research, conducted in early 1997 using interviews with 249 retail traders in Phnom Penh, shows that even though women are gaining economi cally, there is no corresponding improvement in their bargaining power. Women continue to view the non-economic contributions of their husbands as more important than their own economic contributions. The social definition of what it means to be a 'woman' is working as an 'undiscussed' force, preventing the issue of the gender division of occupa tion, with women at the lower end of the social status, from even appearing on the bar gaining table.

Purpose – Information ethics, as is well known, has emerged as an independent area of ethical and philosophical inquiry. There are a number of academic journals that are devoted entirely to the numerous ethical issues that arise in connection with the new information communication technologies; these issues include a host of intellectual property, information privacy, and security issues of concern to librarians and other information professionals. In addition, there are a number of major international conferences devoted to information ethics every year. It would hardly be overstating the matter to say that information ethics is as "hot" an area of theoretical inquiry as medical ethics. The purpose of this paper is to provide an overview on these and related issues.Design/methodology/approach – The paper presents a review of relevant information ethics literature together with the author's assessment of the arguments.Findings – There are issues that are more abstract and basic than the substantive issues...


Purpose: We have evaluated the mutations of the OPTN gene, which has been reported to be associated with the normal tension glaucoma (NTG). Methods: The OPTN gene was analyzed in 53 patients with NTG and 40 normal subjects. Genomic DNA was extracted from the blood samples of each patients, exon 5 and exon 6 of the OPTN gene were amplified by PCR and DNA sequencing was performed. Results: No mutation was found in normal subjects. But three kinds of point mutation (G412A, C459T in exon 5, G577C in exon 6) were found in 7 patients with NTG. Conclusions: We report the novel point mutations of OPTN gene in NTG patients. This shows the possibility of diagnosis of NTG by detecting the mutation of OPTN gene.


(E)-Benzohydroximoyl chlorides have been examined for the first time and are shown to react (as the conjugate ion) > 107-fold more slowly than the corresponding (Z)-benzohydroximoyl chloride anions. This large rate difference is attributed to the favourable antiperiplanar lone pair on the adjacent nitrogen which facilitates Cl– loss from the (Z)-substrate. The (Z)-benzohydroximoyl chlorides were formed by direct chlorination of (E)- or (Z)-benzaldoximes while the (E)-chlorides were formed by acylation of these (Z)-isomers, photoisomerisation and separation, and then subsequent deacylation in situ.


PurposeThis study aims to investigate whether firms involved in a major corruption scandal, with broad ramifications across several emerging and advanced markets, design the content of their corporate codes of conduct to either improve corporate ethical standards and practices or merely manipulate the impression of stakeholders.Design/methodology/approachThis study adopts an impression management perspective. It uses content analysis techniques to examine the codes of conduct adopted by seven Brazilian engineering and construction multinationals accused of corruption. The analysis covered five major themes: (1) forms of corruption, (2) values or principles, (3) interested parties, (4) procedures and routines and (5) punitive action.FindingsThe study provides detailed evidence that the codes of conduct adopted by these firms are mere artifices that aimed at meeting legal requirements but do not target the relevant corporate audience involved in grand corruption. At best, such a code may impede petty and bureaucratic corruption.Originality/valueThis research contributes to improving the understanding of how Latin American multinationals adopted codes of conduct after a major scandal and how they failed—at least to some extent—to design codes complying with established corporate governance principles. It shows that management manipulated the impression of stakeholders by selectively adopting or omitting certain terms, examining or concealing various issues and addressing mainly petty crimes rather than grand corruption. It also identifies areas where Western ethical values conflict with established practices and cultural norms in Latin America.


As an effective teaching method,multimedia has been commonly adopted in the field of neurosurgy. The paper focused on a detailed comparison between characteristics of traditional teaching method and that of multimedia. Based on this teaching experience and through comprehensive analysis,the conclusion was drew that the appropriate integration of mutimedia and conventional teaching method was an optimized teaching method.


In a limited number of microorganisms, branched-chain fatty acids have been reported to be major constituents of lipids (M. Kates, p. 27, in R. Paoletti and D. Kritchevsky [ed.], Advances in Lipid Research, vol. 2, Academic Press, Inc., New York, 1964). The point of branching of the single methyl group in the fatty acid chain occurs at the penultimate carbon atom in the iso-acids and at the antipenultimate carbon atom in the anteiso-acids. Several members of the homologous series of both isoand anteiso-acids have been reported in various microorganisms [S. Akashi and K. A. Saito, J. Biochem. (Tokyo) 47: 222, 1960; R. W. Walker and I. S. Fagerson, Can. J. Microbiol. 11:229, 1965; T. Kaneda, J. Bacteriol. 93:894, 1967]. In a recent study, we found that the principal fatty acid of Corynebacterium acnes, Propionibacterium freudenreichii, and P. shermanii was a saturated C15 branched-chain acid (C. W. Moss et al., J. Bacteriol. 94:1300, 1967). However, the position of the methyl group was not determined. The presence of large amounts of C15 branched-chain acid (range: 24 to 49% of total fatty acids) ini each of 27 isolates of C. acnes and in single strains of each of the above Propionibacterium species suggested a close relationship among strains and possibly among -pecies. Since this finding may be of some value in the identification and taxonomy of these bacterial species, we wanted to determine the position (iso or anteiso) of the methyl group in the C15 branched-chain acid. This would enable us to assess the possibility of an even closer relationship among these organisms than was shown previously by us and by others (H. C. Douglas and S. E. Gunter, J. Bacteriol. 52:15, 1946). Twenty-two strains of C. acnes, two strains of P. acnes, and one strain each of P. freudenreichii and P. shermanii were utilized in these experiments. C. acnes cultures were isolated from a variety of clinical sources at diverse geographical locations; all Propionibacterium cultures were obtained from the American Type Culture Collection.

Abstract: The initial boundary value problem for a class of nonlinearly damped Petrovsky equation utt +∆2u + a(1 + |ut|)ut = b|u|pu in a bounded domain is studied. The existence of global solutions for this problem is proved by constructing a stable set in H2 0 (Ω), and obtain the energy decay result through the use of an important lemma of V.Komornik. Meanwhile, under the conditions of the positive initial energy, it is proved that the solution blows up in the finite time and the lifespan estimates of solutions are also given.


MAN KNAB theory leads to his EDUCATION AND KNAB, which hypothesizes that educa tion is undertaken as a consumption activity And the OUTPIAN Press Corps The tiny country of OUTPIA had always man aged to survive the upheavals that flitted through her long history. And she would manage to sur vive this one. She had emerged from feudalism with a good set of social institutions. She had met rebellion with flexibility, responding with ac comodation rather than castigation; ever changing but unchanging; extending freedom only by tem pering it with responsibility. Since the founding of the OUTPIAN ECONOMIC ORDER (OEO), capitalism had promised opportunity and com fort to those with sufficient foresight to be born


In Russian National Security Doctrine 2020, one of the improvements of higher education is the development of "interaction of educational organizations and research centers with industrial enterprises". The document "development of secondary vocational education system in order to prepare qualified workers in accordance with the best world standards and advanced technologies" is interpreted as an important condition for ensuring national security in the field of science, technology and education. In our opinion, it's cannot be realized without the involvement of the economic, technological and managerial resources of industrial enterprises, and, consequently, the organization of the network interaction of higher educational organizations and enterprises. This study is devoted to the organization of networking of institutions of higher education with enterprises, which was developed in accordance with the basic requirements of employers. The effectiveness of this approach to learning was proven during a research experiment.

[reaction: see text] A "Cp(2)Zr" equivalent is generated under mild conditions (THF, room temperature) by reducing Cp(2)ZrCl(2) with cheap and readily available mischmetall (an alloy of Ce, La, Nd, and Pr). Coupling reactions, including those of terminal alkynes, can efficiently be achieved by using this reagent.


"THE NATION is only the aggregate of individual conditions, and civilization itself is but a question of personal improvement," argued Samuel Smiles in his 1859 Self-Help, the work that codified the supremacy of aspiration over occupation as a marker of identity for thousands of readers on the ill-defined boundary of the lower-middle and upper-working classes (16; ch. 1).1 Smiles's importance, then and now, lies not in his invention of "self-improvement" as a defining feature of this group, but rather in his skill at publicly expressing the complex set of ideals and values that had already been worked out in, and expressed by, small groups of improvers for at least two generations.


In particle-based physics simulations, the information about which particles belong to the boundary of the system and which are considered internal is, in general, an information that is useful but hard to obtain in an efficient way. This information can be applied to generate the free surface of the fluid or to compute the surface tension, among other applications. Techniques found in the literature may present satisfactory results, but in general they are sensible to the problem scale, particle distribution and involve computationally expensive operations such as matrix inversion. The goal of this study is to present an alternative with lower computational cost at runtime by transferring some of the work to a preprocessing step using offline learning.

This article is dedicated to the role and significance of the Iranian proxy-groups in the system of international relations in the Middle East and national security structures of the Islamic Republic of Iran. The relevance of this work stems from significant increase of the Iranian influence in the region over the past ten years. The article includes research of the activity of Iranian proxies in specific countries (Lebanon, Syria, Iraq); analysis of their genesis and increasing political activity; research of their influence on the augment of conflict potential between Iran and Israel; analysis of these groups' functions in the system of national security of Iran. The author of the article points out, among other factors, that the Hezbollah movement in Lebanon has considerably strengthened its positions in the recent years due to a number of reasons, first of all, the movement's victory in the military conflict with Israel in 2006. The second reason is various political alliances and coalitions with other Lebanese parliamentary parties; the third one is considerable military experience obtained by Hezbollah in the civil war in Syria (2013–2019). The author also emphasizes Hezbollah's significant influence in the military and political spheres of Iraq, which are held by the pro-Iranian "Al Khashd al Shaabi" created by Shi'a parties. In conclusion, the author provides a review of  these groups's relations with Iran and their prospects. The Iranian proxy groups play a significant role in the national security of Iran. Taking Iran's confrontation with the US, Israel and Saudi Arabia into account, these groups are providing deterrence against probable aggression of the US and Israel towards Iran.


Automotive systems are changing rapidly from purely mechanical to smart, programmable assistants. These systems react and respond to the driving environment and communicate with other subsystems for better driver support and safety. However, instead of supporting, the complexity of such systems can result in a stressful experience for the driver, adding to the workload. Hence, a poorly designed system, from a usability and user experience perspective, can lead to reduced usage or even ignorance of the provided functionalities, especially concerning Adaptive Driver Assistance Systems.In this paper, the authors propose a combined design approach for user behavior evaluation of such systems. At the core of the design is a mixed methods approach, where objective data, which is automatically collected in vehicles, is augmented with subjective data, which is gathered through in- depth interviews with end-users. The aim of the proposed methodology design is to improve current practices on user behavior evaluation, achieve a deeper understanding of driver's behavior, and improve the validity and rigor of the named results.


In this work, a novel bimetallic Fe–Mg/MOF was synthesized through a cost-effective and rapid hydrothermal process. The structure, morphology, and composition were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy. Further, the Brunauer–Emmett–Teller (BET) measurement showed a 324 m2 g−1 surface area for Fe–Mg/MOF. The Fe–Mg/MOF achieved 1825 C g−1 capacity at 1.2 A g−1 current density, which is higher than simple Fe-MOF (1144 C g−1) and Mg-MOF (1401 C g−1). To assess the long-term stability of the asymmetric device, the bimetallic MOF supercapattery underwent 1000 charge/discharge cycles and retained 85% of its initial capacity. The energy and power densities were calculated to be 57 W h kg−1 and 2393 W kg−1, respectively. Additionally, Fe–Mg/MOF showed superior electrocatalytic performance in hydrogen evolution reaction (HER) by demonstrating a smaller Tafel slope of 51.43 mV dec−1. Our research lays the foundation for enhancing the efficiency of energy storage technologies, paving the way for more sustainable and robust energy solutions.


There is considerable disagreement over whether the gas/liquid surface of water is positive due to the presence of surface-active hydrogen ions or negative due to the presence of surface-active hydroxyl ions. Much has been written and many experimental and simulation studies have been undertaken. We critically analyze these studies to establish what is known unambiguously and what assumptions underlie these opposite views. The conclusion reached after this examination is that there is much misunderstanding over the strength of the evidence for hydrogen ions being surface active and less support for the positive surface than generally regarded. The surface of neutral water is negatively charged.


DOI: http://dx.doi.org/10.5915/22-2-13552 In this study we describe 86 patients at the main hospitals of Arbil, Sulaimaniah and Dohuk provinces (the Autonomous Area) who in 1987 had surgically proven hydatid infection. Infection rate was higher in females than in males in the Sulaimaniah province, whereas the opposite was true in Arbil and Dohuk provinces. Females were mostly housewives. Age ranged from 7 to 80 years, with the majority between 21-40 years of age. Most organs of the body were involved, especially liver, lung, peritoneum, spleen and other organs. The organ most commonly affected was the liver, followed by the lungs. Those having single organ involvement accounted for 83.7% of patients, while 16.3% had multiple organ or site involvement by hydatid cysts.


Modern technologies are complex systems, which creates demand for an equally complex supporting technical infrastructure that is implemented through a variety of standards affecting all stages of technology-based economic activity. The development, production, and integration of the components of technology-based systems require standards for such disparate functions as materials characterization, equipment calibrations, setting data formats, and consummation of market transactions. These functions of standardization not only increase productivity but assure domestic customers and those in other economies that a component will perform as desired within the broader product system technology. The trend in corporate strategy toward specialization and the resulting networks of firms that develop, disseminate, and integrate these technologies mean a greater distribution of R&D among materials and component suppliers and integrators of product and service systems that now characterize high-tech supply chains. The consequent increase in market transactions requires an additional standards infrastructure to reduce the greatly increased costs involved in consummating these transactions between suppliers and users. The need to be commonly used means standards have publicgood characteristics, which leads to underinvestment in their technological content and in the processes for actually promulgating them and managing their use over a technology's life cycle. Further, because standards are a heterogeneous infrastructure, having multiple forms and hence economic roles, different combinations of public and private investment in the supporting "infratechnologies†are needed. In response to the need to effectively manage the multiple roles of standards, this monograph assesses their economic nature and impacts over the entire technology life cycle and the consequent implications for public policies required to effectively provide this critical infrastructure.


This paper describes a research investigation into the implementation of the Last Planner System (LPS) in a road construction project. LPS is known to be the most developed practical use of Lean Construction. It focuses on minimising the negative impacts of variability, uncertainties, buffers, making projects more predictable, creating reliable work plans and convalescing collaborative planning. LPS is unpopular in highway and road construction projects, as a lot of case studies have been recorded of its application on infrastructure and building projects as against highway and road projects. However in the road project. In order to achieve this aim, an Action Research strategy is adopted using different data collection methods such as interviews, observation and survey questionnaire. The initial state of production plan reliability within this case project was observed to be highly unreliable with a high degree of variability. However as the implementation commenced, production plans were stabilized with an improved reliability in the schedules. The results from this study demonstrate that although a road construction process is a linear process, a number of benefits were still recorded in terms of improving construction planning and control processes, during the implementation.


The electrically induced bending of nonionic polyvinyl alcohol gels, bending over 90° within 100 ms, is the fastest motion in the field of electroactuation of polymers. This rapid bending produces initial mechanical vibrations followed by a durable displacement that contrasts highly with the relaxation observed with elastomer- and polyelectrolyte-based actuators. Here, we characterize the bending process using video imaging and laser detecting technology and establish a physical model for the electromechanical conversion, based on our observation of an induced solvent migration. Our results show excellent agreement between the measurements and calculations. This study provides general rules for understanding the electrically induced bending of isotropic dielectrics and may also shed light on nonmuscular biological engines.


We prove Chung-type laws of the iterated logarithm for general Levy processes at zero. In particular, we provide tools to translate small deviation estimates directly into laws of the iterated logarithm. This reveals laws of the iterated logarithm for Levy processes at small times in many concrete examples. In some cases, exotic norming functions are derived.


Glass ceramics obtained via a true glassy phase are homogeneous and pore free, which makes them interesting for electronic applications, especially in the GHz frequency range. We discuss the glass-ceramic system with Ba4Al2Ti10O27 as the main crystalline phase and show material properties, including dielectric properties measured up to 110 GHz. Application examples are shown for filters and antennas in the GHz frequency range. The extremely high material homogeneity makes very precise manufacturing possible and enables MHz accuracy and reproducibility in GHz applications. The high linearity of the material properties is shown as well and makes high power applications, e.g., in cell phone base stations, possible. Also, applications in the MHz range are discussed.


In my earlier work, I utilized " found " vintage or family photographs as a starting point for the final photomontage. In my more recent works, I experiment with different types of image processes using my own photography as a means to further strengthen the " finding of my own voice " through the presentation of " landscapes " that are charged with symbolism and emotion.


From classical fixed‐time signal‐detection theory, it is known that the basis for optimum receiver design is likelihood ratio. For composite‐signal hypothesis problems, the optimum receiver forms a total likelihood ratio that is an average over all the various possible signals that could be transmitted in the observation interval. When the transmitted signal is composed of one of a finite class of waveforms that is repetitively generated by a random independent trigger process, the various possible signals that could occur grow with time so that a classic nonsequential realization requires a growing memory size that is impractical to implement. In problems of this type, the optimum reciever can be realized in an equivalent sequential fashion that is an adaptive realization. Using adaptive realizations, the receiver can be realized with a memory size that remains fixed in size. [This work supported by the U. S. Office of Naval Research, Code 468.]


In this paper we will take a critical look at the research and development of signal and image processing technologies and new applications of existing technologies to improve crime control and crime prevention. Signal and image processing techniques are used in many aspects of sensing the environment both during a crime and in the post-crime analysis of the scene. Common themes of research will be discussed with reference to applications such as: Ballistocardiogram Human Presence Detection Technology Demonstration, Electromagnetic Portal and Acoustic Systems for Concealed Weapons Detection, Uncooled Thermal Imagers to Enhance Law Enforcement Operations, Technology along the U.S. Border, In-Vehicle Voice Verification (IVVVS), Methamphetamine Cook and Detection Technologies, Radar-Based Through-the-Wall surveillance system, Speaker Identification and Voice Stress Analysis Technology Evaluation.

Electrochemical reduction of aryldiazonium salts on an iron electrode in acetonitrile leads to the attachment of aryl groups to the iron surface. We investigated aryl groups substituted with 4-alkyl chains (−CH3, −C4H9, −C12H25, −OC12H25, −OC16H33), with 4-halogeno substituents (−I, −F, −CF3, −OCF3, or −C6F13), or with five fluorine atoms (pentafluoro phenyl, −C6F5). Attachment of these groups was characterized by FTIR, XPS, and capacity measurements. It is shown by measuring the polarization resistance and the corrosion current that these layers provide a significant protection against corrosion.


Corporate bond dealers build up considerable inventories for which they rely on short-term funding. I provide empirical evidence that dealers' inventory financing constraints are a crucial determinant of the costs of their liquidity provision in corporate bond markets. Constructing a unique dataset that links dealer identities with transaction prices, I show that dealer-specific financing constraints (as proxied by their CDS spreads) explain a substantial part of the variation in the inventory cost component of the effective bid-ask spread. Compared to low volatility bonds, the liquidity provision of high volatility bonds is more sensitive to inventory costs, especially during periods of funding stress. Finally, exploiting a quasi-natural experiment, I show that the relaxation of funding constraints through a Federal Reserve emergency credit facility temporarily alleviates liquidity problems among eligible dealers.

: This study aimed to determine the supervision of the Environmental Service of Central Sulawesi Province in managing waste at Undata Palu Hospital. This type of research is descriptive, with the number of informants as many as 13 people, which is determined using the purposive technique. The data analysis method uses three steps: data condensation, presenting data (data display) and drawing conclusions or verification (conclusion drawing and verification). Based on the results of the study, it was concluded that the supervision of hospital waste management by the Central Sulawesi Environmental Service had not run optimally, this was due to the limited number of human resources, and the competence of the supervisory officers from the Central Sulawesi Environmental Service was still limited. In terms of the equipment owned by the Central Sulawesi Environmental Service, the laboratory equipment for testing the validity of the data is still incomplete and operational vehicles are still limited in number and the lack of budget owned by the Central Sulawesi Environmental Service because each year the budget obtained is still minimal. Schedule The implementation of control carried out by the Central Sulawesi Environmental Service is still not optimal, where in the last three years, regular (scheduled) monitoring has no longer been carried out, only reports in the form of documents on the implementation of environmental management are used as a reference for the Environment Agency in monitoring The performance of hospitals in managing their waste, this happened because after the disaster that hit Palu City at the end of 2018 ago, the implementation of supervision could not be carried out maximally, because the activities of institutions, both hospitals and the Environmental Service, were still focused on improving the facilities and infrastructure of the agency.


Human epidermis contains a subset of epidermal T cells that can mount an immune response by migrating through the skin and into the peripheral lymphnodes to proliferate before re‐entering the epidermis. The cytokine IL‐7 is shown to be localized to the basement membrane of normal human skin. Furthermore, culturing in the presence of IL‐7 causes increased adhesion of epidermal T cells but not peripheral blood T cells to the major epidermal basement membrane protein, laminin‐5. The mechanism for increased T cell adhesion to laminin‐5 is due, at least in part, to an increase in the cell surface expression of the integrin α3β1. Epidermal T cells cultured in IL‐7 that are strongly adherent to laminin‐5 are shown by flow cytometry to consist of a variety of subsets ; therefore, the increase in cell adhesion is not due to an outgrowth of one T cell subset during culturing. We hypothesize that in vivo, exposure to IL‐7 is required for epidermal T cell adhesion to laminin‐5.


The incidence of urinary bladder cancer in population of Samara and Tambov oblasts in 1960-1998 was studied. Intensive and standardised indices of incidence were calculated by indirect method. Comparative analysis of trends in the incidence in general as well as in gender and age groups revealed higher incidence in Tambov oblast, while its stable increase was shown in Samara oblast.


Thermal Barkhausen effect is observed in poly(vinylidene fluoride/trifluoroethylene) [P(VDF-TrFE)] copolymer films for the first time. Barkhausen pulses arise at phase transition close to the Curie point during both heating and cooling without an external electric field. Three types of current pulses are obtained associated with nucleation and domain wall motion. The switched dipole number under one pulse is generally much less than 1% of the sample's total dipoles.


With the development in technology there has been drastic increase in the use of power electronic equipment's resulting in the increase of harmonics in source current or ac mains current. Now a day's, Nonlinear loads are widely used in industries. The Nonlinear loads like Arc furnaces, locomotives, welding equipment's, fluorescent lamps etc..; generate harmonics into the power system. Due to these nonlinear loads, draws non-sinusoidal current and create voltage drops in the power system and also overheating of equipment's, communication interference, capacitor failure etc... Therefore, it is considerable to reduce or eliminate the harmonics in the system. Conventionally, L-C passive filters were used to solve the problem of harmonics to filter out current harmonics to get sinusoidal supply current. Modern Active power filter's (APF) are superior in harmonic's filtering performance compared to traditional passive filters. Among the SSAF and SAPF, Shunt Active Power Filter (SAPF) is most preferred because this filter provides higher efficiency and more flexible compared with a passive power filter. Shunt active power filter (SAPF) with power circuit either a voltage -sourced PWM converter equipped with a DC capacitor or a currentsourced PWM converter equipped with a DC inductor. This filter have the multiple functions like harmonic filtering, damping, isolation and termination, reactive power control for power factor correction and voltage regulation, voltage-flicker mitigation. In this paper, it is planned to design a d-q based controller for VSC based active power filter for harmonic compensation. The simulation results have been done by using MATLAB/SIMULINK.


more specific for the political arrangement and specific political theory that of the institution Dworkin is interpreting. Concrete rights also have to be broken into two varying ideas. First, "They must be institutional rather than background rights and they must be legal rather than some other form of institutional rights". (Dworkin, 1977 p. 101) Dworkin notes this distinction because it would not be fair to have every person in our political arrangement wanting particular rights simply because they feel their virtue is better than someone else's. The institution must have rights so that the political arrangement can be talked about and understood. Institutional rights and background rights may diverge from one another. For example, a judge may feel a certain way or that an individual case should be decided in a certain way, but if the institutional rights do not allow for that to be made a decision, then the judge is stuck in a hard place.

The distribution of Megacrania tsudai Shiraki, a threatened stick insect species in Taiwan, is limited to the Hengchun Peninsula and Green Island, with only a small population in each locality. Previous studies on this insect were mostly focused on its morphology and life history. In the present study, the 16S rDNA gene was used as a marker to study the genetic diversity, phylogenetic relationships, and phylogeography of M. tsudai. Crude DNA was extracted from 46 samples of eggs or partial mid-leg tarsi collected from three populations (Jioupeng, Kankau and Green Island). Sequence analyses of 16S rDNA, ~550bp, from 23 successfully amplified samples showed no variation at all between and within populations. This result suggests that the populations of M. tsudai in Taiwan may have either descended from a limited number of ancestors (founder effect), or have experienced a bottleneck effect due to a small population size and restricted habitats. From a conservation point of view, the perfect genetic homogeneity of the M. tsudai populations will have a negative impact on the long-term survival of this species in Taiwan. In addition to enhancing their legal protection, it would also be helpful to conserve this species by preserving its habitats and broaden its distribution range. It is also very important that we explore potential genetic variation and preserve it in the wild populations.


Theoretical and experimental studies are reported to determine the feasibility of applying electron blackbodies'' to thermionic energy conversion. The conclusion from this work is that the size of the effusing hole is governed largely, not by the size of the cavity to which it is the exit, but by the physical limitations imposed by the nature of the electron atmosphere within the cavity. It is shown that the density of the electron atmosphere within the cavity is only large in a region close to the surface of the emitting walls and may be characterized by a parameter d, which does not depend on the size of the cavity. A quartitative expression is given for the conditions under which the effusing hole behaves as an eiectron blackbody. It is shown that for the electron emission density to be large enough for useful thermionic energy conversion, the size of the effusing hole has to be too small for practical consideration. (auth)

: Seasonal hydrologic behavior of small forested catchments in the Appalachians was studied using oxygen-18 as a tracer. Oxygen-18 in samples of precipitation and streamflow were used to determine seasonal variations of subsurface water recharge and movement within two 30-40 ha forest catchments (Watershed 3 and 4) at the Fernow Experimental Forest in northcentral West Virginia and a 1,100-ha forested catchment in northcentral Pennsylvania for the period March 1989-March 1990. Precipitation or throughfall in both regions showed expected seasonal sine-wave variations in oxygen-18 with minima occurring in winter and maxima occurring in summer. Baseflow stream samples for both small watersheds at Fernow showed similar seasonal sine-wave variations in oxygen-18 with amplitudes damped by about 90% and time lags to peak oxygen-18 of about 110 days relative to precipitation variations. Damping of amplitudes on the Fernow basins was equivalent to a mean transit time for subsurface baseflow water of about 1.5 years. Baseflow oxygen-18 on the larger Pennsylvania basin showed no discernible seasonal pattern in oxygen-18, which indicated mean transit time of subsurface water was at least 3-5 years. These results imply that both small Femow basins exhibit relatively shallow and rapid recycling of subsurface water and that both basins would respond quickly and similarly to changes in watershed condition. On the larger Pennsylvania basin, a much larger, more slowly-cycling groundwater reservoir exists and baseflow would respond much more slowly to changes in watershed conditions.


The tendency for the mind to wander to concerns other than the task in hand is a fundamental feature of human cognition, yet the consequence of variations in its experiential content for psychological functioning are not well understood. Here, we adopted a multivariate pattern analysis approach, simultaneously decomposing experience sampling data with neural functional connectivity data, revealing dimensions that simultaneously describe individual variation in self-reported experience and default mode network connectivity. We identified dimensions corresponding to traits of positive, habitual thoughts and spontaneous taskunrelated thoughts. These dimensions were uniquely related to aspects of cognition, such as executive control and the ability to generate information in a creative fashion, and independently distinguished well-being measures. These data provide the most convincing evidence to date for an ontological view of the mind-wandering state as encompassing a broad range of different experiences and that this heterogeneity underlies its complex relationship to psychological functioning.


This article examines how the development of techno-marketing campaigns might facilitate the engagement of university students in voluntary activities on campus which promote active citizenship and community cohesion where there is a concern about a low take up of such opportunities. The increasing influence of technology upon the forms of social interaction presents opportunities for the use of digital technology and interactive marketing to encourage student engagement. The term 'technohesion' is developed to understand the intermingling of these social and technological changes enabling an exploration of the use of techno-marketing to promote engagement in activities which seek to further community cohesion. We call for future research that incorporates the insights from the concept of 'technohesion' to counter the absence of technological and attitudinal considerations in relation to attracting students to voluntary, extra-curricular activities which seek to promote social cohesion.


Programmable Logic Controller (PLC) is widely used in manufacturing industry nowadays. Hence, the competence of students towards PLCs is important to produce graduates who can meet the demands of the industry. In this regard, this study was conducted to identify the level of competency students in the Electronic Technology programme at Vocational College (VC) in terms of cognitive and psychomotor aspects in developing PLC programming. The design of the study is by survey. This study was conducted in three KVs in Perak and Johor. A total of 90 respondents were involved in this study. The research instrument used was test questions to measure knowledge level while practical question is used for measuring student skills. The findings were analyzed by using descriptive statistics and presented in percentages. Based on the findings of the study, the students competent at both level. However, overall students tend to master the theory rather than practice. Therefore, the findings from this study can be used by KV lecturers for Industrial Automation courses in order to improve the quality of teaching and learning.


Economic globalization encourages coffee farmers to prepare themselves to adapt and compete. In dealing with this issue, Margamulya Coffee Farmer Group has transformed into a cooperative under the name of the Margamulya Coffee Producers Cooperative (MCPC). MCPC sold 80% of its coffee production to PT Taman Delta Indonesia (PT TDI) and was committed to its permanent supplier. In fulfilling its role as coffee suppliers, farmers were faced with a lot of capital needs to produce quality coffee. MCPC needs capital to pay farmers cherry as well as processing and marketing costs. This study aims to describe the coffee value chain in MCPC, to identify the perpetrators and their business processes, and to design financing pattern suitable for farmers and MCPC. The method used was case study at MCPC using value stream mapping technique. The results show that there are two value chains in coffee agribusiness in MCPC while the actors in the chain consist of Farmer-Cooperative-Exporter and Farmers-Cooperatives-Retail (café/others). The business process in farmers remained in coffee producing, while the cooperatives focused on processing and marketing. The result of this study shows that the proposed financing model of value chain financing for its success requires the involvement of stakeholders from outside the supply chain. Value chain financing for structured markets gives more guarantee of business sustainability due to market certainty and price. This encourages farmers to maintain both the quantity and quality of their coffee products.

[Objective]To investigate the occupational health conditions in a 1-bromopropane manufacturing plant and to understand the relationship between occupational exposure and health.[Methods]Information on the technical process of 1-bropromane production and the occupational history,basic information,and health examination data of 21 workers were collected.Fixed site and personal sampling methods were used to determine concentrations of 1-bromopropane at the selected working spaces and individuals respectively.Relationship between 1-bromopropane exposure and health condition of the workers was analyzed.[Results] 1-bromopropane was detected at all of the selected worksites with a maximum of 153.08mg/m3at the site close to the receiving pot,the highest geometric mean concentration(43.62mg/m3) was found in the distilling room,and the lowest(1.95mg/m3) was located outside the production line.There were no significant differences between the active and the passive samples in the individual exposure levels(P0.10).The health examination data showed no obvious health effects caused by 1-bromopropane exposure.[Conclusion] The workers' health is not affected by 1-bromopropane manufacturing under the current exposure level.


Based on previous measured data and adsorption isotherms experiment of six coal samples from different stratification of the southern Qinshui basin, discussed the diversity between different stratification on adsorption characteristics and its main controlling factors. The results show that: In the macro level, bright coal layer has the highest adsorption capacity, Langmuir volume (VL) is up to 40m3/t ; the adsorption capacity of dull coal and semi-dull coal is relatively low. By analyzing the relationship between the Langmuir volume of coal petrography and various factors, discovering the Langmuir volume has a positive correlation with vitrinite content, vitrinite reflectance, fixed carbon content, and micro-pores content, but negative correlation with ash, while it has no significant linear relationship between moisture, porosity, permeability. By grey relational analysis, it shows that the impact is in descending order from vitrinite content to fixed carbon content, vitrinite reflectance, micro-pores content, ash content.


The results of the magnetization measurements of single crystal of Yba2Cu3Oy with Tc equals 91K are adduced. The temperature, field and time dependencies of the remnant magnetization Mr(T, B, t) were obtained using VSM method for the temperature range from 4.2 K to 75 K for Hc configuration. The single crystal has been irradiated by the fast electrons with fluences up to 2 X 1018 cm-2. The relaxation of Mr(t) obeys to the logarithmic law for the time interval t equals 1 h for whole temperature range except the approximately 30-50 K interval for starting and irradiated states. After irradiation the Jc decease despite the flux creep reduction. The irradiation become less effective at high temperatures. The results are discussed in frame of conventional flux creep theory and of the interaction model of radiation defects with the background ones.


In this paper, the normal mixture model subjected to general linear restriction for component-means based on linear regression is proposed, and its fitting method by EM algorithm and Lagrange multiplier is provided. This model is applied to gene clustering of microarray expression data, which demonstrates it has very good performances for real data set. This model also allows to obtain the clusters that an analyst wants to find out in the fashion that the hypothesis for component-means is represented by the design matrices and the linear restriction matrices.


Chinese Permanent Resident(Green Card) System was established 1985 Law of Exit and Entry Administration of Aliens,and developed in 2004 Regulations on Examination and Approval of Permanent Resident of Aliens in China. It is a milestone of historical development of Chinese migration law.The system enhances the internationalization of China,and standards the examination and approval of permanent residence of foreigners in China.However,numbers of legal issues could be found in the system.It existed not only in legislative structure and legislative goal but in system design and operational details.The legal issues might be resulted from incomplete knowing and understanding of permanent resident system,and the relations between international migration and China social and economic development.These issues consume the advantages of China being a State with a very developing migration law,and hinder the high-speed development of Chinese migration law.It should be ignored in no case and is great significance to make a careful and comprehensive critical legal thinking.


In this paper, correlation between the headphone's acoustical characteristics and the subjective preferences is analyzed, and a possibility of predicting the subjective preferences using the acoustical characteristics is investigated, The headphone's acoustical characteristics include the total harmonic distortions, the variation of the frequency response which were measured by separate channel and the inter-aural correlation coefficients, Those characteristics were measured in a noise-free anechoic chamber, using a head and torso simulator, The subjective preferences were scored in terms of loudness, clearness, spaciousness, fullness and overall impression, In the subjective listening test, 12 subjects were participated who have plentiful listening experiences, The programs include 5 kinds of musics; korean popular song, pop song, light music, male-voice and classic, The 8 models of the headphones were employed, including 4 closed-type circumaural headphones, 2 open-type supraaural headphones and 2 intra-concha headphones, A significant test was carred on the results from the subjective test, using a two-way ANOVA test, The correlation coefficients between the acoustical parameters and the subjective preferences were computed, Experimental results showed that the variation of the magnitude of frequency response measured from a right channel revealed higher correlation with the subjective preferences. Whereas the inter-aural correlation coefficients have very low correlation coefficients.


Fisher's (protected) least significant difference (LSD) procedure has been suggested in the design and analysis of multiarm clinical trials with survival endpoints. In this article, the power of this procedure is evaluated and compared with that of Bonferroni and Hochberg procedures by Monte Carlo simulations under three scenarios of alternative hypothesis encountered in three arm clinical trials with survival endpoint. The approach of sample size calculation based on the power of a global test in the first step of Fisher's LSD procedure is also evaluated and contrasted with that based on Bonferroni adjustment. It is shown that Bonferroni and Hochberg procedures are more powerful than Fisher's LSD procedure when two specific pair-wise comparisons are of interest, while Fisher's LSD procedure is the most powerful if all three pairwise comparisons are performed. It is recommended that the formula of Makuch and Simon be used in the sample size calculations for all three types of alternative hypothesis considered in this article. However, the Hochberg procedure should be used in the analysis if only two specific pairwise comparisons are of interest and the Fisher's LSD procedure should be used in the analysis when objective of the trial includes all of three pairwise comparisons.

This publication, a "quarterly," contains the transactions of the comparatively new Rontgen Society. From the 'Editorial' with which this number commences we learn that the work of the Society will follow three chief lines of enquiry :?(1) a study from a purely scientific standpoint of the nature of Rontgen Rays; (2) a practical enquiry into the best apparatus for their production ; (3) an investigation of all the details bearing on their useful application. It is with the third branch of enquiry that the medical profession will find itself most in touch, leaving the two first mainly to the workers in


Networked multimedia applications involve a set of cooperating streams that together form a multimedia session. Existing QoS provisioning schemes for multimedia applications in cellular networks either allow composite streams to compete with one another for resources or else provide QoS to a session as an atomic entity, leaving to the application the task of managing QoS for the individual streams. The main contribution of this work is to propose a novel local QoS provisioning scheme for cellular networks that is aware of the relationships between the streams that compose a session. Our new Multimedia Session-Aware QoS (MUSAQ) provisioning scheme manages the QoS of the individual streams in a session, and, with the knowledge of their relationships, it prevents destructive competition between the streams. Further, by allowing application-specified prioritization between streams in a session, MUSAQ features a significant improvement in performance over session-unaware schemes.

One of the important components in geothermal power generation is steam turbines. One of the decreases in steam turbine performance is caused by excessive workload due to continuous operation. Maintenance of steam turbines through important overhauls is carried out to improve the performance of steam turbines. Actual conditions with ideal conditions are important to know and analyze to know the performance of steam turbines. The operational performance of steam turbines at PT Pertamina Energi Geothermal Area Kamojang can be seen from the value of turbine working specifications (Wt), and isentropic efficiency (ηt). Parameters in the form of inlet pressure (P1), outlet pressure (P2), inlet temperature (T1), outlet temperature (T2), and flow rate (m/s) are searched using the ChemicalLogic SteamTab application and linear interpolation methods to determine the value of enthalpy and entropy. The results were obtained that the value of isentropic enthalpy (h2s) before the overhaul amounted to 2,127.41 kJ/kg and after an overhaul of 2,145.91 kJ/kg. Turbine power value (Ẇt) before overhaul was 30,702.88 kW and after overhaul was 36,304.7 kW. Efficiency after overhaul decreased ±1.4% of efficiency before the overhaul.
