Few people have studied the problem of physiological data transmission at the rates required by NASA's Life Sciences-Advanced BioTelemetry System (LSABTS). Implanted telemetry eliminates the problems associated with wire breaking the skin, and permits experiments with awake and unrestrained subjects. Our goal is to build a low-power 174-216MHz RF transmitter suitable for short range biosensor and implantable use. A system architecture based on a frequency-locked loop frequency synthesizer is presented, and a novel differential frequency discriminator that eliminates the need for a frequency divider is also proposed. The Hajimiri phase noise model was used to optimize the VCO for minimum power consumption. A test chip was fabricated in a 0.5Pm, 3V CMOS process. Measured phase noise for a 1.5mW, 200MHz ring oscillator VCO is -80dBc/Hz at 100KHz offset, showing good agreement with the theory. Currently, NASA-Ames Research Center is developing the Life Sciences-Advanced BioTelemetry System (LS-ABTS) to conduct space-based animal research [1]. In vivo experiments require anesthetized animals and hard-wired connections to the implant creating a risk of infection due to transcutaneous wires. Wire breakage, movement artifacts, ground loops and 60Hz pick-up can also cause problems. In collaboration with the Fetal Treatment Center at UCSF, NASA is also developing a system for wireless telemetry of physiological parameters of fetuses for monitoring and identifying distress after pre-natal surgery [2]. An implant that will monitor heart rate, temperature, pH, and amniotic fluid pressure is required to operate in utero for up to 3 months. A low-power highly integrated radio transmitter is key to the success of these projects. The most important parameter of an implanted biotelemetry system is power dissipation. Power dissipation and implant lifetime determine the size of the battery which ultimately determines the size of the implant. A significant portion of the power budget for any implantable telemetry system is allocated to the generation of the RF carrier. Given this need for small, low-power wireless devices for biotelemetry, a low-power, integrated frequency synthesizer is required. Traditionally, frequency synthesizers have been implemented using a phase-locked loop (PLL). Figure 1 shows the block diagram and power budget for a state-of-the-art CMOS PLL synthesizer used in microprocessor clock generation [3]. In a PLL synthesizer, the VCO frequency is divided and then compared to a reference frequency by a phase detector. The phase detector drives a low-pass filter that generate the control voltage for the VCO. The major sources of power dissipation are the VCO (73%) and the frequency divider (22%). To reduce power we have to address these blocks first. We propose a frequency-locked loop (FLL) architecture (fig.2) that uses a differential frequency discriminator (DFD). In the past, quadricorrelators and rotational frequency detectors [4] have been used to aid the frequency acquisition process in a PLL, but have been superseded by simpler phase-frequency detectors with charge pumps [5]. The proposed FLL does not require a frequency divider, which represents 22% of the power budget for the PLL example just shown. The FLL can perform frequency comparison directly without a divider (N=1) by using a DFD implemented with switched capacitor circuits. In operation, current I1 is generated by switches S 1, 2 and capacitor C 1, and is inversely proportional to the reference frequency driving the switches, FREF, and the value of C 1. Current I2 is also inversely proportional to the feedback frequency, and the value of C 2. Current mirror M1/M2 force these two currents to be equal, resulting in the following relationship: FOUT = (C1/C2) FREF where the output frequency is determined solely by the capacitor ratio, C1/C2. A linear analysis using a single pole filter shows that this is a first order system, and thus inherently stable (neglecting sample-data effects). A PLL tracks the phase noise of the reference signal, relaxing the close-in phase noise requirements of the VCO (provided that the reference has better phase noise than the VCO). However, a FLL tracks the VCO's frequency, not phase, forcing more stringent requirements on the VCO. The VCO's power dissipation is determined by the frequency of operation and the phase noise performance required. In biotelemetry, data rates are low, and channel spacing wide, relaxing the phase noise requirements. This makes it feasible to use voltagecontrolled ring oscillators which are easy to integrate and do not require any external components. The VCO design is critical in the performance of the FLL synthesizer as the phase noise at the output of the FLL is solely a function of the phase noise of the VCO. The VCO consists of a 4-stage differential ring oscillator (fig.3). The differential buffers used (fig.4) have been shown to have excellent noise and power supply rejection characteristics [6]. Frequency control is achieved by changing the biasing of the buffer stages which determine the delay through each cell. The layout of the ring oscillator is symmetrical and load balanced to avoid any skewing between the phases. The Hajimiri phase noise model [7] was used to optimize the VCO for minimum power dissipation. The single-sideband phase noise of a differential


The harmonic series is the infinite series ∞ n=1 1 n = 1 + 1 2 + 1 3 + 1 4 + · · · The series diverges to infinity even though lim n→∞ 1/n = 0. The divergence of the harmonic series was first proved by the medieval French scholar Nicolas d'Oresme (1323–1382). His proof is the following. Since the series 1 + 1 2 + 1 2 + 1 2 + · · · diverges, the harmonic series diverges as well. We can also prove that the harmonic series diverges using integration. 0 x y 1 1 2 3 4. .. n n + 1 y = 1/x The sum of the area of the shaded rectangles is larger than the area between the x-axis and the graph of y = 1/x over 1 ≤ x ≤ n + 1. Therefore, ln(n + 1) = n+1 1 1 x dx ≤ 1 + 1 2 + 1 3 + · · · + 1 n. Since lim n→∞ ln(n + 1) = ∞, we conclude that the harmonic series diverges.


Sixteen intact crossbreed (Texel*local breed) lamb, weighting approximately 40 kg each, were used in a 2 * 2 factorial design experiment to evaluate the effects of HQ on nutrient digestibility and nitrogen balance. The four rations containing soybean meal (SBM) or urea as main nitrogen source with or without HQ (S1, S0, U1 and U0 respectively) were fed in digestion and nitrogen balance trials. Apparent digestibility of CP, OM, DM and NDF did not affected by either nitrogen source of addition of HQ, but addition of HQ improved ADF digestibility significantly (P < 0.05) by 18% regardless of nitrogen source. There was significant difference between urea-N excretion in the urine (P < 0.05) for SBM ration and urea ration. However, neither nitrogen source nor HQ addition altered nitrogen balance. No interactions between nitrogen source and HQ were observed throughout the trial. Administration of HQ in SBM ration tended to decrease urea-N output in urine, indicating that this urease inhibitor was likely to improve endogenous urea-N utilization. Results of this study demonstrated that addition of HQ to total mixed ration improved ADF digestion without negative effect on nitrogen balance.


and adequate analgesia can be obtained for this class of operations by local and regional methods combined, our experiences with deep-seated thyroid tumours jammed behind the sternum and clavicle amply prove. Each surgeon will have to decide for himself whether this is enough without total anaesthesia in highly excitable patients. If local analgesia is employed in these cases it must, I think, be combined with morphia, or some other efficient general sedative and inust be carried out by one quite familiar with the details of the method and able to complete the infiltration quickly and efficiently in a way to gain the confidence ofthe patient. I am afraid this will usually have to be the surgeon himself, who knows the ground he will have to cover and the amount of force he will have to use in his deep dissection. This may appear at first sight a rather ungracious remark to make to an audience so largely composed of ancesthetists, but it is certainly not intended to be 'so. No one could feel more strongly than I do the great debt that all surgeons owe to the special anesthetists who have done so much to make general ancesthesia safe for the patient and helpful to the operator.

Objective: Endoscopic valve therapy aims at target lobe volume reduction (TLVR) that is associated with improved lung function, exercise tolerance and quality of life in emphysema patients. In several trials, a TLVR greater than 350 ml was considered to be indicative of positive response to treatment. However, it is not really known what size of TLVR can be considered as being crucial following valve implantation. Methods: TLVR, FEV1 (forced expiratory volume in 1 second), RV (residual volume) and 6-MWT (6-minute-walk test) were assessed prior and around 3 months after valve implantation in 119 patients treated from 2012-2013. TLVR was calculated based on MDCT scan analysis using quantitative imaging software (Apollo; VIDA Diagnostics, Coralville, IA). MID estimates were calculated by anchor-based methods (anchors: FEV1, 6-MWT, RV) and by distribution-based methods. Results: Patients treated by valves experienced a mean change of 0,11l in FEV1, of -0,51l in RV, of 46,6m in 6-MWT and a mean TLVR of 955ml. Using a linear regression based on each of the three anchors, and ROC analysis based on ΔFEV1 and ΔRV, the estimated MID for TLVR was between 890 ml and 1070 ml (between 41% and 54% of the baseline target lobe volume). Conclusion: These MID estimates for TLVR derived from the anchor-based method that identifies precisely the patients clinical outcome are much higher than assumed in previous trials and are useful for sample size determination in new studies.


Objective To study the hemostatic effect of ochre and to explore its mechanism.Methods High dose(12 g/kg) and low dose(6 g/kg) of the aqueous extract from crude and calcined ochre were given to mice by gastric gavage for 5 days,and then the bleeding time(BT),coagulation time(CT) and platelet count(PLC) as well as the prothrombin time(PT) and the activated partial thromboplastin time(APTT) and thrombin time(TT) were measured by the antomatic blood agglutination instrument.The content of fibrinogen(Fg) was detected by phenol reagent colorimetry.Results The water decoction from high-dose calcined ochre could obviously reduce the BT and CT.The aqueous extract from both crude ochre and calcined ochre could reduce the PT,KPTT and TT.Meanwhile,both the crude ochre and calcined ochre could increased the content of Fg,but the difference was insignificant.Conclusion The ochre has hemostatic effect and its main hemostatic mechanism is related to the activation of the intrinsic and extrinsic blood coagulation system.


The higher operating temperatures in gas-turbine engines enabled by thermal barrier coatings (TBCs) engender new materials issues, viz silicate particles (sand, volcanic ash, fly ash) ingested by the engine melt on the hot TBC surfaces and form calcium–magnesium–alumino–silicate (CMAS) glass deposits. The molten CMAS glass degrades TBCs, leading to their premature failure. In this context, we have used the concept of optical basicity (OB) to provide a quantitative chemical basis for the screening of CMAS-resistant TBC compositions, which could also be extended to environmental barrier coatings (EBCs). By applying OB difference considerations to various major TBC compositions and two types of important CMASs—desert sand and fly ash—the 2ZrO2·Y2O3 solid solution (ss) TBC composition, with the potential for high CMAS-resistance, is chosen for this study. Here, we also demonstrate the feasibility of processing of 2ZrO2·Y2O3(ss) air-plasma sprayed (APS) TBC using commercially developed powders. The resulting TBCs with typical APS microstructures are found to be single-phase cubic fluorite, having a thermal conductivity <0.9 W·(m·K)−1 at elevated temperatures. The accompanying Part II paper presents results from experiments and analyses of high-temperature interactions between 2ZrO2·Y2O3(ss) APS TBC and the two types of CMASs.

ABSTRACT The short caliper splint herein illustrated was developed by me while in charge of the orthopedic service of the U. S. Army base hospital at Fort Sam Houston, Texas. It has proved to be uniformly useful in (a) ununited fractures below the knee; (b) weak union, to guard against mishap, and (c) tuberculous or other disease of the ankle or joints of the foot when it is desired to take the weight off of the foot. The splint is intended for the treatment of ambulatory cases.The right angled portion at the lower end is inserted into the hole in the shoe, as in the application of the long caliper splint. The shoe is now pulled on until the heel lacks about 1 inch of coming in contact with the bottom of the shoe. Next the leather cuff is snugly laced up, and following this the shoe is laced as


According to health reports of Malang city, many people are exposed to sexually transmitted diseases and most sufferers are not aware of the symptoms. Malang city being known as a city of education so that every year the population number increases, it is at risk of increasing the spread of sexually transmitted diseases virus. This problem is important to be solved to treat earlier sufferers sexually transmitted diseases virus in order to reduce the burden of patient spending. In this research, authors conduct data mining methods to classifying sexually transmitted diseases. From the experiment result shows that K-NN is the best method for solve this problem with 90% accuracy.


Nitrite can catalyze oxidation of Fe~(2+) to Fe~(3+) by dissolved oxygen. So the nitrite can be indirectly determined by the thiocyanaate spectrophotometry. Nitrate was reduced to nitrite by zinc powder. The content of nitrate was calculated out from determined total amount of nitrite. A catalytic spectrophotometry for simultaneous determination of nitrite and nitrate in meat products has been developed. The linear range of nitrite was 1.5~5.0μg/25mL. The reduction efficiency of nitrate was 99.2%. RSD's of determination results(n=6) were less than 2.1%. The recoveries of standard addition of samples were 99.1%-101.9%.The molar absorbtivity was 7.66×10~4L·mol~(-1)·cm~(-1).


TOWARDS the end of the eighteenth-century, Lazzaro Spallanzani (1794) demonstrated that the location of obstacles and prey by insectivorous bats depends on hearing rather than on their inadequate vision. Captive bats avoided fine wires in complete darkness or when their eyes were destroyed. Blinded bats were released and on subsequent recapture were found to have caught and eaten just as many insects as normal animals. Yet when their ears were blocked, seeing bats were reluctant to fly and blundered clumsily into quite large objects. Many critical experiments confirmed the importance of hearing but the mechanism remained a mystery. Although similar results were obtained by several of Spallanzani's friends they were discredited by the influential Cuvier and the matter was almost forgotten. In 1920, Hartridge observed bats in flight and suggested that they might produce high frequency calls, inaudible to man, and navigate by means of echoes. He pointed out the advantages of high frequencies for producing echoes from small objects. Since 1938, Griffin, Galambos, Dijkgraaf, Mohres and others have amply demonstrated the truth of this theory and a comprehensive review of these researches has been published by Griffin (1958). Their importance is such that a new type of sense at a distance must now be accepted, an active sense in which the larynx and ears take over the role of the eyes for orientation. The echolocation cries of bats fall in the frequency range of 20-120 kilocycles per second, and are produced as discrete pulses of high intensity. The larynx is highly specialized for the production of these sounds ^Elias, 1907; Mohres, 1953). In general there is heavy ossification and fusion of the cartilages to form a rigid framework and the cricothyroid muscles are capable of applying great tension to the short, light vocal cords. Other modifications, such as the resonating chambers of the Rhinolophidae, may be present. The ear is specialized in several ways. The pinnae are very large, especially in the genus Plecotus, with various accessory structures (Figs. 1, 2 and 3); the tensor tympani and stapedius muscles are very well developed; the cochlea may be relatively enormous as in the Rhinolophidae, and


In recent years, the knowledge of the circulation and study of the Latin classics in the Middle Ages has been vastly increased due to the publication of Birger Munk Olsen's seminal studies and the continued publication of volumes of the Catalogus translationum et commentariorum . This chapter focuses on new manuscript discoveries that made thanks to these two projects, emphasizing in particular the medieval reception of the poetic corpus of Ovid. It addresses how such manuscript discoveries can enhance and compel a reevaluation of a commentator's influence and significance. The accessus begins with a brief overview of Ovid's familial background and his early life. The survey of newly discovered manuscripts containing medieval commentaries and accessus to classical authors (primarily Ovid) has underlined the importance of the Catalogus project for our knowledge of the circulation and influence of literary criticism on the auctores . Keywords: accessus ; Catalogus ; Latin classics; manuscript discoveries; Ovid

Fertilizer applied quantity in the actual production should be N 150 ~210 kg·hm-2,P2O5 45 ~120 kg·hm-2,K2O 90~120 kg·hm-2.


Self-doped semiconductors have recently attracted extensive interest as highly efficient photocatalytic materials because the electronic properties can be modulated without sacrificing the chemical stability of the parent material. In this report, we report the facile synthesis of Sn2+ self-doped SnS microparticles via a simple template-free hydrothermal route. Because of the ability to successfully tune the band structure while minimizing defect generation, self-doped SnS could potentially serve as an efficient photocatalyst of wastewater. Here, Sn2+ self-doping results in insertion of an energy level slightly below the conduction band of SnS, thereby decreasing the photoexcitation energy. Furthermore, dopant sites can act as charge trapping sites, which can consequently minimize problematic charge recombination. Synthesized materials were characterized by various spectroscopic, microscopic, and surface characterization techniques, all of which confirmed the formation of self-doped SnS. The Sn2+ self-doped SnS photocatalyst successfully reduced carcinogenic Cr(VI) to the water-insoluble Cr(III) form under visible light illumination. The best photocatalytic efficiency was obtained from an optimal balance between increased numbers of trapping sites leading to longer charge carrier lifetime, and decreased distance between trapping sites, favoring charge recombination. We anticipate that similar methodologies can be applied to other non-stoichiometric semiconducting photocatalysts with tunable electronic properties and enhanced photocatalytic efficiency.

A continuum growth equation in 1+1 dimensions is obtained by considering the contributions to the underlying current from kinetics of adatoms on the surface. These considerations reproduce the slope dependent term that represents a stable or an unstable growth depending on the sign of the associated coefficient. In addition an h to -h symmetry breaking nonlinear term is obtained. Implications of this term on stable to unstable transition are discussed. This term is tilt independent and is expected to be present independent of the source of the current in the conserved growth. Computer simulation based on a zero diffusion bias model is used to verify some of the predictions of the minimal growth equation. It is shown that the growth equations for cellular automata type models involving instantaneous relaxations can be obtained from the proposed method by addressing the corresponding kinetics of adatoms.


One advantage yet to focus on in scientific literature is the beneficial use of virtual autopsy (virtopsy) for investigating minimal tumor burden. Our hypothesis is that virtopsy assists in the understanding of therapy resistance of cancer patients or cause of death in patients with minimal tumor burden.1 The well-established textbook scenario describes a patient dying from cancer by the tumor mass compressing surrounding tissue (e.g. brain tumors), or destroying surrounding tissue resulting in organ failure (e.g. multi-metastatic diseases), or destroying blood vessels causing lethal bleeding. Furthermore, patients may die from tumor-induced cachexia, which is a consequence of the tumor's interference with the body's energy homeostasis. However there are some instances when it is difficult to explain a tumor-related death, particularly when a patient dies of head or neck cancer. For example, when major tumor mass is not detectable, there are no signs of cachexia, or evidence of an immediate consequence of chemotherapy or radiotherapy. When patients might die exhibiting a small metastasis in the lung or a small local tumor, it is concluded that they died of the cancer because there is no other apparent cause of death (e.g. cardiac disease). This is concluded despite none of the classical cancer-related causes of death being established. In view of this therefore is an unexplained mechanism of how a tumor can kill a patient. The majority of current cancer therapies are aimed at killing tumor cells. This is done either direct ly (by chemical agents or radiat ion), or indirectly (by depriving the tumor from nutrients, or activating and redirecting the immune response against the cancer). This variety of therapeutic approaches is reflected in modern therapies such as PDL-1 blockers, VEGF-inhibitors, tumor-vaccines or Proteasome-inhibitors. However the observation that a fair number of patients with minimal detectable tumor mass die of cancer, given that treatment options described were considered, highlights gaps in knowledge that require filling as well as development of new potential therapeutic approaches. As a first step we propose epidemiological studies be undertaken these are required in order to obtain


Abstract. This paper describes the photogrammetric approach to find the geometric shape of a paraglider. As its geometry is only available during the flight this had to be done under special conditions. The layout of the camera positions was limited by the strict safety of the pilot as well as a wind and flying situation that guarantees a stable geometry of the object for several minutes. The data acquisition was finally carried out in the area of Lake Garda and the pilot had the challenging task to handle the calibrated camera using a telescope arm in predefined positions during his flight. The evaluation of the 3D position of selected discrete points representing the paraglider's shape was done by employing a bundle adjustment software and led to very satisfying results which were also proof of the stability of the paraglider during data acquisition as well as of the symmetry of the resulting shape.

The author is sure that retrospective historical and pedagogical analysis of the value component of teachers work lets substantiate missionary function of the teachers. Genesis of this function is caused by evolution of social consciousness, collective identification and integration of the teachers as a social and professional group.


The operation of the new Baiyun International Airport in Guangzhou will promote the development of its peripheral industries,including those of the PRD and even South China.In this paper,a tentative plan about building up an industrial zone around the airport is suggested.On the basis of analyzing the transportation,natural condition,labor force resources and the characteristics of the industrial spatial structure,by the speciality theory of industrial economic development,a spatial development structure,which consists of 3 ring belts,the new airport,its adjacent areas and the area along the airport transportation highroad with high accessibility,is put forward.The industries,such as service,electronic information,agriculture for airplane passengers,jewelry and leather industry,should be regarded as the engine of the regional industries to integrate the intrinsic resources and optimize the industrial layout,so as to strengthen the function of the airport and protect natural environment of northern Guangzhou.


Part IV of this study found that it is possible to enhance business performance by making and executing plans in consideration of activities that encourage self-reflection. Part V focuses on the effectiveness of being aware of such activities to achieve greater results. Factors for realizing significant achievements are clarified through experiments and measurements. The possibility of increasing a-waves by (1) singing and (2) wearing a watch with a magnetism-discharging device is also examined.


Policy-making and -execution by representatives make a great impact on social system. If inappropriate representatives are elected and unsuitable policies are executecd, unreasonable social impact and enormous social cost will be produced. Scientific knowledge on the way of electing representatives are now desired. Most mayors seems to be re-elected if they want. Some mayors, however, fail and new mayors win in some cities. This paper aims to analyse relation between change of mayors and voters' preference structure. A conceptual model of mayor's election is built so as to analyse the effect of voters' preference structure on the state of social system. Computer simulation shows the results:a mayor elected is changed more often and the state of social system becomes more unstable as the preference structure of voters changes from Goal-Realization-Oriented to Policy-Attitude-Oriented. Hotelling's Theorem(Median Voter's Theorem)is shown as a special case by the simulation.


Well aligned quasi-straight single-walled carbon nanotubes (SWCNTs) and straight SWCNTs bundle have been prepared in large scale by anode-arc vaporization of graphite with metallic catalysts. Various parameters such as the catalyst preparation, the kinds and pressure of the buffer gases, the quantity of anode-arc current intensity, and the method of purification have been examined. The influence of these parameters on the deposited carbon yield is reported, together with observations of the produced material. Improvement in synthetic techniques has resulted in the optimal conditions for the production of large quantities of high quality SWCNTs in our semi-continuous synthesis method. The formation of carbon nanotubes (CNTs) was studied briefly in this paper. Owing to the magnetic pinching effect of arc current, the CNTs arrange in parallel lines along the arc current direction.


s of Papers Presented at the 16th Annual Meeting, Surfers Paradise, 19th May, 1983 NEUROTOMES: A NEUROANATOMIC METHOD OF CLASSIFICATION OF MULTIPLE CONGENITAL MALFORMATIONS K. North and J. McCredie Department o f Surgery, University o f Sydney, NSW. It has been suggested that complexes of multiple congenital malformations, involving limbs and viscera, may be caused by embryonic neural crest injury. Structures supplied by the sensory and autonomic nerves derived from the injured zone of crest would suffer defective development through impairment of neurotrophic influence. (McCredie, 1976) Our study aimed to examine this concept, by a retrospective analysis of autopsy findings in babies who died of multiple congenital malformations associated with phocomelia. Sclerotome maps of the segmental sensory innervation of the limbs (Inman and Saunders, 1944) were used to analyse the skeletal defects in terms of their nerve supply. From a review of the literature, the segmental contribution of neural crest to the autonomic innervation of internal organs was ascertained, and thus "viscotome" maps were constructed. Application of sclerotome and viscotome maps to the data derived from the autopsy reports showed a neuroanatomic correlation in 90% of cases. PURINE SYNTHESIS IN RAT EMBRYOS UNDERGOING ORGANOGENESIS Peter 6. Rowe and Sandra E. McEwen. Children's Medical Research Foundation, Royal Alexandra Hospital for Children, Camperdown. NSW. The purpose of this study was to establish the mechanism(s) of purine nucleotide synthesis in cultured rat embryos with the ultimate aim of further exploring the metabolic interelationships between the embryo and its yolk sac. We have shown that the cultured rat embryo undergoing organogenesis (9.5 to 11.5 days gestation) together with its associated yolk sac, synthesises purine nucleotides via the de novo synthetic pathway. Although both the embryo and its yolk sac contain significant levels of the purine base salvage enzymes, adenine phosphoribosyltransferase and hypoxanthine phosphoribosyltransferase, the culture medium, which consists largely of rat serum, contains no measurable quantities of salvageable purine bases or nucleosides but high activity levels of the purine catabolic enzymes, adenosine deaminase, nucleoside phorphorylase, guanase and xanthine oxidase. Short term pulse-chase experiments with adenine and guanine, carried out under virtually serum free conditions, confirmed that purine base salvage mechanisms were active and that there was no significant net transfer of purine between the embryo and its yolk sac. A comparison between the specific radioactivities of the [14 C] glycine added to the culture medium for the studies of the de novo synthetic pathway and the purine bases in both the cellular nucleotides and the nucleic acids indicated the existence of a large glycine pool which almost certainly was derived from the degradation of medium serum proteins by the yolk sac. While there is no clear cut data available on the in vivo plasma levels of purines which could be potentially utilized to meet the demands of the embryo it is evident that the de novo pathway is adequately developed to meet these needs. REFRACTORINESS TO BRONCHOCONSTRICTION FOLLOWING HYPERVENTILATION WITH COLD DRY AIR M. Soto Quiros, L. I. Landau Department of Thoracic Medicine, Royal Children's Hospital. f a r k ville. Vic. The response of asthmatic children to exercise is typically biphasic. During the first 2-3 minutes there is a rise in flow rates associated with bronchodilation followed by a fall in flow rates due to bronchoconstriction. Fifteen subjects, 3 females and 12 males, aged 9 to 31 years were studied. All had a history of exercise induced asthma. A series of tests were performed within a period of 2 weeks, each at the same time on different days. The first test consisted of 6 minutes of hyperventilation with cold dry air (HCDA) followed by 30 minutes of rest and then 6 minutes of HCDA. The second test consisted of 6 minutes of hyperventilation with warm humidified air (HWHA) followed by 30 minutes of rest and then 6 minutes of HCDA. The subjects hyperventilated to match ventilation recorded during a previous standard 6 minute exercise challenge. Spirometry was recorded before and at 2.4 and 6 minutes during the hyperventilation and at 3,5,10,15,20 and 30 minutes after the hyperventilation. Subjects during hyperventilation showed a biphasic pattern of response similar to that seen with exercise. The rise in FEV, was greater following a second HCDA than a first HCDA, HWHA or HCDA after HWHA. HCDA caused a significant fall in FEV, and refractoriness was seen with significant less fall following a second HCDA. HWHA did not cause a significant fall in FEVl and the fall in FEV, with HCDA following the initial HWHA was not significantly different from that with HCDA and no previous hyperventilation. We propose that refractoriness induced by exercise or hyperventilation with cold dry air may be due to the refractoriness at the trigger site and related to modification of the cyclic AMP cyclic GMP balance in nerve endings or mast cell walls.

M n a discussion paper recently released by the Prices Surveillance Authority, Dr I Ian Manning, of the National Institute of Economic and Industry Research, A argues that the social responsibilities of banks warrant their being obliged by regulation to provide 'basic banking' services free of charge to the poor (Manning, 1995:21). In Dr Manning's view, the imposition of account-keeping and transactions charges on bank accounts held by the poor is inefficient because some poor people will be induced to leave the banking system, thus obliging the community to forgo die benefits of 'universal banking' (akin in Dr Manning's opinion to universal pri mary education). It is also inequitable because those poor people who do retain bank accounts will spend a disproportionately high share of their limited incomes on bank fees and charges as compared with the rich.

Maillard reaction products (MRP) obtained by reaction of glucose, fructose or xylose with arginine, cysteine, glutamic acid, histidine, lysine or valine were studied with regard to their antioxidative properties. Model systems consisting of emulgated linoleic acid were used to evaluate the antioxidative effect of the MRP. The antioxidative effect was found to be strongly dependent on the choice of reactants, especially the amino acid. While MRP from glutamic acid with glucose or fructose showed no antioxidative properties, potent antioxidative products were obtained from, for example, histidine or lysine with any of the three sugars, or from arginine with xylose only.

The reaction between histidine and glucose was studied with regard to the influence of pH and of the molar ratio of amino acid to sugar on the antioxidative effect of the MRP formed. Neutral or slightly basic initial pH was found to favor the production of antioxidative products. Furthermore, the antioxidative effect was found to be more favored by a high histidine concentration than by a high glucose concentration.


Web probing is a valuable tool to assess the validity and comparability of survey items. It uses different probe types—such as category-selection probes and specific probes—to inquire about different aspects of an item. Previous web probing studies often asked one probe type per item, but research situations exist where it might be preferable to test potentially problematic items with multiple probes. However, the response behavior might be affected by two factors: question order and the visual presentation of probes on one screen versus multiple screens as well as their interaction. In this study, we report evidence from a web experiment that was conducted with 532 respondents from Germany in September 2013. Experimental groups varied by screen number (1 versus 2) and probe order (category-selection probe first versus specific probe first). We assessed the impact of these manipulations on several indicators of response quality, probe answer content, and the respondents' motivation with logistic regressions and two-way ANOVAs. We reveal that multiple mechanisms push response behavior in this context: perceived response burden, the focus of attention, the need for justification, and verbal context effects. We find that response behavior in the condition with two screens and category-selection probe first outperforms all other experimental conditions. We recommend this implementation in all but one scenario: if the goal is to test an item that includes a key term with a potentially too large lexical scope, we recommend starting with a specific probe but on the same screen as the category-selection probe.


Java Island is inhabited by 368 species of sedentary birds and 126 species of wandering birds, but the number of species that live in urban areas is still unknown. Green Open Space (RTH) in the urban area of Yogyakarta is depreciating, but many species of birds are able to adapt and survive. The existence of birds in an urban area, such as airport area could potentially harm economic and human safety because of bird strikes. The research objective was to determine the community of diurnal birds and habitat used of by birds in The Adisutjipto International Airport Yogyakarta (AIAY) area as a preliminary study. The study was conducted from 10 July to 29 Aug 2017 in AIAY and surrounding area. Diversity data retrieval used Point of Abundance Index method and analyzed by the Shannon-Wienner Diversity Index. Types of the guild were directly observed and were determined based on literature review and the proportion of bird communities based on the type of guild were analyzed with modified use of importance value index. Conservation status was determined according to Government Regulation No. 7/1999 and IUCN Redlist. Nesting and foraging were observed directly and analyzed descriptively. The diversity of bird species in the AIAY area was moderate and taxonomically included 38 species that covered 36 genera and 23 families. The species composition between each zones do not have significant difference There were six species of birds that were protected, but the population status of all types were least concern. The composition of bird species based on the type of guilds is granivorous, insectivorous, mollucivorous, frugivorous and nectarivorous. Some birds used the area around the runway for foraging and crossing and potentially endanger the safety of flight, i.e., munia (Lonchura spp.), white-throated needletail (Collocalia linchi), Eurasian tree-sparrow (Passer montanus), grey heron (Ardea cinerea), and cattle egret (Bubulcus ibis).Java Island is inhabited by 368 species of sedentary birds and 126 species of wandering birds, but the number of species that live in urban areas is still unknown.

The article pays attention to Oles Honchar, an iconic figure of Ukrainian culture. In 2023, we celebrate the 105th anniversary of birthday of the famous Ukrainian, whose creation is relevant today and inspires descendants to be indomitable and to strive for eternal values. Not only our, but also the entire European cultural space, in particular the cine-space, records the actualization and a request for understanding the heritage of prominent Ukrainians who created the Ukrainian culture at different times and influenced the formation of orientations and value dominants. The modern historical background – terrible and insidious aggression against Ukraine by the northern under-empire is particularly important. Today, both Oles Ponchar's figure and his works as a writer are worthy of attention not only by specialists in philology and cultural studies, but also of the general public. And this is due to the artist's relay of dominant values characteristic of the Ukrainian cultural space. He is the bright representative, who in his linguistic creation demonstrates the ethical and attitudinal aspirations of the Ukrainian people, as well as its morality. The study attempts to comprehend the modern Ukrainian documentary cine-texts on Oles Honchar, which were created prior to the Russian full-scale invasion in 2022, in particular, O. Honchar's "The Cathedral" (1993); The Giant of Steppes;The Architect of Human Soul (2001); Oles Honchar. The Cathedral (2008); Global Star of Oles Honchar (2011); Oles Honchar. People and Their Destinies (2014). All these films are especially focused on the role, in the artist's life, of the novel The Cathedral, which divided his life into before and after. And this is not accidental, because the work is directed at deep meanings and philosophical reflections on the eternal, it appeals to every soul. And the latter is already the transcendental realm, that is, which is beyond the possible experience. The article also focuses on the writer's figure in the films The Architect of Human Soul and Oles Honchar. The Cathedral. The article's special attention is paid to the relevance and extraordinary timeliness of such cultural products as Kateryna Strelchenko's film Oles Honchar. The Word as a Weapon, as well as other documentary cine-texts, biopics about outstanding Ukrainians that are already available and yet to appear in our and global cultural spaces.


The rate of absorption of D-glucose and L-histidine from the entire small intestine of the rat when measured by an intubation technique was not affected by infestation with the nematode Nippostrongylu8 muris. On the other hand, absorption of D-glucose from the infested jejunum when measured in vivo by a perfusion technique was severely reduced. The rate of gastric emptying was not affected by the infestation. There was a direct relationship between gastric emptying and the rate of absorption of glucose.


A new cavity-based method to measure the complex permittivity of dielectric materials is presented here. The method uses a double-ridged waveguide for the cavity instead of the widely used rectangular waveguides, thus enhancing the operational frequency bandwidth by twofold. The bandwidth enhancement is advantageous when measuring the permittivities of frequency dispersive specimens. Building on the perturbation theory, this paper develops the measurement equations required for permittivity extraction. The measurement errors induced by the approximations in the perturbation theory are evaluated using numerical simulations, and the errors are quantified for different specimen sizes and dielectric constants. The experimental results are also presented. The complex permittivities of three common plastic specimens are measured at frequencies of around 3, 5, and 8 GHz using one double-ridged cavity. For comparison purposes, the same samples are also measured using two rectangular cavities operating in the S- and X-bands. Good agreement in the measured permittivity values is observed.


For 4 to 5 years, there has been a fever of studio condominiums in Taipei housing market. Not only is the number of new projects growing devastatingly, the selling of these studio condominiums also is at a speed far greater then that of other housing types. By the influence of the media, people tend to link this phenomenon to "Single phenomenon", hastily assume the bloom as the consequence of increasing unmarried population in our society. On the other hand, terms like "low price", "low down-payment", "easy to sell", and "high profit", overwhelm the consumers and stimulate more investments. In conclusion, it either makes the mistake to speak as the dominant system and hide the real purposes, or only mention the superficial features of studio condominiums' as one of the "housing product". But these points of view can't help us understanding the inner meaning of this particular housing type. Therefore, in this study, I will look into the process of the production and marketing of residential commodities. I will search through history of the developing of studio condominiums in Taipei and the distinctive mechanism of real estate market in relation with this building type in Taiwan. Special effort is made to analyze the consideration process of producers and consumers in the construction and purchase of studio condominiums, and to understand the special characters of this building type in the housing market. According to the history research, studio condominium is not a recent invention. In fact, it has occurred in Taipei housing market since early 1970's. There have been three waves of studio condominium fever since then. The studio condominiums change in location, character and layout followed on the growth of Taipei City. The characters of "profit-oriented" and "high-flexibility" are what remained constant till now. After analyzing my interviews with the producers and consumers contributing the latest studio condominiums fever, we concluded that although studio condominiums are in nature limited space, meant for the housing of increasing unmarried populations and city workers, they are presented as investments with "high-exchange value" in the housing market now. Other significant meanings are also defined. First, the construction industry uses this building type to revive the failure of pre-sale housing projects. They also use the high unit price of studio condominiums to raise the housing price of surrounding area and create a "real-estate-will-keep-growth" myth. Second, housing consumers (mainly investors according to this study) earn their profit and keep the sense of security by the rent income and the rise of housing price. Some investors even indulge themselves in the atmosphere of investing studio condominiums. Investment in studio apartments has become a game or even a life style for them. Producers or investors imagine, borrow and shift from the expectancy of future. Studio condominiums have become the elixir of the modern city. This phenomenon has made housing too expensive for those really need and made the use of land more inefficient. This studio condominiums fever has spread seeds that will one day become potential serious problems in our society.


Recursion is a programming technique in which a solution can be expressed by a subroutine invoking itself either directly or indirectly. Many problems can be expressed simply using a recursive approach, however one of the drawbacks of using recursion is that it requires a stack, and often one does not know how much stack space is needed to obtain a recursive result. Stack overflow often results in spectacular failure with strange, often unrepeatable behaviour. Paraffin is a suite of generic units that can add parallelism to iterative and recursive problems. Some of the generics involve a load balancing technique described as "work-seeking". It was found that the recursive work seeking algorithm could be extended to also provide stack safety whereby the generics monitor the amount of remaining stack space and avoid stack overflow using a technique similar to load balancing. The stack safety feature also makes it attractive to consider Paraffin for use with code destined for execution on a single core. This paper describes how the recursive work-seeking algorithm was extended to provide the stack-safety feature, and then goes on to report some performance results using the generics.

Generally, NOT of large mechanical structures, such as vessels and pipes in nuclear power plants, are examined depending on national codes. The damaged mechanical parts detected during the periodic NOT are repaired or replaced after the evaluation. However, an unexpected incident can occur in the structure if cracks propagate and exceed the tolerance limit during operation. Therefore, there is a need to develop NOT techniques to detect micro-damages in the vessels and pipes. In this paper, we propose a cylinder-type magnetic camera to satisfy this need. We use a cylindrically integrated, Hall sensor arrays (CIHaS) as a magnetic sensor to achieve magnetic image. We use a solenoid coil as the magnetic source of a magnetic camera to achieve high crack-detection ability. Examining the cracks on a pipe model specimen allows us to verify the proposed method.

Geothelphusa dehaani, a freshwater crab species endemic to Japan, has the largest distribution range amongst the 19 known species in the country. Due to its low dispersal capability and restricted habitat to freshwater, it serves as an excellent model for understanding gene flow between geographically isolated populations. In this study, we analysed the genetic relationships of 26 G. dehaani populations collected from different locations in the Japanese archipelago using two mitochondrial DNA regions - cytochrome oxidase subunit I (COI) and cytochrome b (cytB). Our results from the analysis of molecular variance (AMOVA) revealed high genetic variation amongst populations and the phylogenetic analysis identified four geographical groups: Clade I - Honshu and Shikoku, Clade II - north-eastern Kyushu, Clade III - southern Kyushu and Clade IV - north-western Kyushu. Notably, Clade IV exhibited the highest genetic distance amongst the observed groupings. These findings highlight the need for further examination of G. dehaani in Kyushu, including morphological and behavioural traits, to better understand the observed diversity within the species in the region.


Phonocardiogram (PCG) and Electrocardiogram (ECG) are the two important signals for cardiac preliminary diagnosis. Using ECG as a reference for segmenting the PCG signal is a simple but reliable technique for the devices with integration capability of PCG and ECG recording. The aim of this work is to analyse the time delay between ECG and PCG at each auscultation site. To do so, we performed the experiments on 12 healthy subjects, where the ECG and PCG signals were collected simultaneously at two sites at each time. Our results reveal that 1) the inter-distance of the electrodes for ECG does not affect the occurrence time of the R-peak. 2) The delay between R-peak and onset of first heart sound (S1) depends on the auscultation site e.g. S1 onset occurs before the R-peak at auscultation site M. This study suggests that small integrated ECG-PCG devices can be made by reducing the distance between the ECG electrodes. In the meantime, distinguishing the auscultation location is necessary for performing more precise PCG segmentation using ECG as reference.

Charge accumulation phenomenon on gas–solid interface greatly restricts the development of HVDC energy transmission system. In this study, the surface charge transport behavior and flashover performance on alumina/epoxy spacer coated by SiC/epoxy composites are experimentally investigated under DC stress. SiC/epoxy composites with varied SiC particle size are fabricated and deposited on spacer surface. Nearly a charge free surface is achieved especially at smaller SiC particle size, even when metallic wires are adhered on spacer surface and connected to high voltage electrode. The DC flashover voltage increases with the decrease of SiC particle size. On the one hand, smaller SiC particle size exhibits more outstanding nonlinear conductivity characteristics, contributing to accelerating charge dissipation, whereas on the other hand, it would introduce plenty of shallow traps due to the increased interfacial regions between SiC particle and epoxy matrix, resulting in aggravating charge accumulation. A theoretical model is proposed to reveal the control mechanism of SiC/epoxy coating with different SiC particle size on flashover performance. The validity of this model can be confirmed based on the surface trap distribution, carrier mobility and our previous investigations on gas–solid interface flashover development process.


The chromene compound is used as a key intermediate for synthesis of new heterocyclic compounds, and it reacted with hydrazonoyl chlorides in presence of TEA to give the amidrazone derivatives , which were cyclized to the corresponding triazepines on boiling with sodium ethoxide. Conversion of compound to the methylthiocarbamate derivative was performed through its reaction with carbon disulfide and KOH followed by treatment with methyl iodide. Compound reacted with hydrazonoyl chlorides in presence of TEA to give thiadiazoles . In addition, chromene combined with aminodithiocarbamic acid in DMF under reflux to furnish the thiosemicarbazide derivative , which in turn interacted with several hydrazonoyl chlorides to give the thiazole derivatives . The structures of the prepared compounds were confirmed from their spectroscopic data and elemental analysis. The synthesized compounds were tested against both monoamine oxidase (MAO)-A and MAO-B and corrected to analyses showed good inhibitory activities especially against MAO-A.


With the rapidl aging of population and the improving of life level,elderly consumers have already got more and more public attention in recent years.The tourism demand of the aged people is enlarging because they have enough spare time and higher disposable personal income.Thus,performing empirical research on elderly travellers has some significance for theory research and practical development.This paper,taking the senior tourists in Sanya city as survey examples,explores the tourism motivation,the tourism experience,and uses the questionnaires to obtain basic data.Through descriptive statistical analysis,the study obtain the specific scores and sorting of tourism motivation,importance and performance of the tourism experience.Through factor analysis,the study acquires 5 common factor of tourism moti vation including"leisure and relax","enjoying the environment","health and sports","family and social interaction",and"private affair".The study introduces Paired-samples T Test and Importance Performance Analysis(IPA)to reveal the differences between emphasis on experience and performance,and puts forward strengths,weaknesses,opportunities and threats in elderly tourism experience items.At last,according to the result of the research and the need of aged peo ple,the study points out some suggestions for the local government and the tourism enterprises.


This paper grew from a first attempt to understand the relationship of a new conjecture of Lusztig [L 2] for representations of quantized enveloping algebras to bis conjecture [Ll] for representations of algebraic groups in characteristic p. The main question here is: Does the new conjecture imply the old? Using results of [APW], it is easy to see this question has an affirmative answer if appropriate irreducible representations of a quantum enveloping algebra at a p root of unity remain irreducible upon 'reduction mod/?'. (Equivalently, the quantum and characteristic p irreducible modules involved, labelled by the same weight, must have the same dimension.) Indeed, Lusztig has conjectured this irreducibility in an equivalent context [L 3], where the weights involved are restricted, and p is sufficiently large. Another Standard hypothesis (equivalent for p ^ 2h — 3) requires that p be at least äs large äs the Coxeter number A, and that the weights in question belong to the Jantzen region, which is contained in the lowest /?-alcove.


: In this article, I investigate the processes, benefits and dilemmas of producing a fashion show as a method of dissemination in arts-informed qualitative research. I examine a project that used a fashion show to analyze and represent interview findings about men's understandings and performances of masculinities. Fashion shows facilitate the dissemination of new qualitative data— what I coin "enclothed knowledge"—which is embodied and inaccessible through static or verbal descriptions. Fashion shows also enable participants to shape knowledge circulation and allow researchers to engage diverse audiences. Despite these benefits, researchers have to be mindful of ethical dilemmas that occur from the absence of anonymity inherent in public performances and therefore I suggest strategies to mitigate these threats to research ethics. Ultimately, I argue that fashion shows advance social justice because the platform can transform narrow, stereotypical understandings of marginalized identities.

Frequency-domain distortion analysis is very important for designing the analog integrated circuits. We propose here a new method based on the Spice-oriented harmonic balance method, where the Fourier transformations of the resistive circuits driven by a periodic input are carried out by the Fourier transfer circuit model. The circuit is composed of the analog behavior models(ABM) of Spice, which can be applied to any kind of nonlinear circuits containing the exponential and/or piecewise linear characteristics. Furthermore, the determining equation of our harmonic balance method is schematically described by coupled resistive DC, Cosine and Sine circuits, so that we can easily obtain the frequency response curves with the DC analysis of Spice. Thus, our approach is quite user-friendly, because we need not derive the circuit equation and the determining equations in our method.


Chapter 5 explores the main features contributing towards the formation of living brand among children within the age 10 to 12-year-old by using a fuzzy logic analysis. From this methodological approach, several interesting insights emerge with regard to children's consumer behaviour, especially the factors of future anticipation, ritual, and autobiographical memory in the priming of the development of a living brand. In this chapter, we are going to expand on the discussion by identifying the antecedents of a successful product using Indonesian market segment from the same age group as the research subjects in Chapter 6. Some of the important elements for success in the children's segment that we identify here include brand personality, brand trust, and brand salience, particularly on how each of them affect brand relationship. When combined with autobiographical memory and buying habituation, this emotional bonding results in brand loyalty. Finally, we utilised a neural network topology in order to fully understand the antecedents of brand loyalty construction within the children's market.


Electrochromic materials have shown great application prospects in electronic display and information storage. In this work, we synthesized MoO3@PEDOT coaxial heterostructure nanobelts by a simple and green in situ polymerization method and investigated their electrochromic properties. This MoO3@PEDOT nanobelts take internal MoO3 nanobelts as mechanical support and growth templates to make the externally PEDOT covered uniformly on the outside. This unique 1D nano-structure has large surface area, provides large number of accessible electroactive sites for high color contrast. It was found that the electrochromic composite films prepared by spin coating MoO3@PEDOT coaxial heterostructure nanobelts on ITO exhibited a high contrast of 31.8%, and colored efficiency up to 86.57 cm2·C−1. It turned out the MoO3@PEDOT coaxial heterostructure nanobelts can improve PEDOT electrochromic properties greatly and will be a suitable choice for smart window application.


Thirty one cases of adenoid cystic carcinoma in the head and neck were treated in our clinic between 1982 and 1998. The patients included 17 men and 14 women, ranging in age from 32 to 77 years. The main affected regions were the tongue to mouth floor, submandibular gland and maxillary sinus. The cumulative survival rates at 5 and 10 years were 86.1% and 68.5% respectively. Histologic findings were classified into three grades, Grade I : tumors with tubular and cribriform areas but without solid components, Grade II : cribriform tumors that were either pure or mixed with less than 30% solid areas, and Grade III : tumors with a predominantly solid pattern. There was no evidence that Grade III tumors were associated with a poorer prognosis in this study. The addition of postoperative radiation therapy was effective for prevention of recurrences.


The fractional vegetation coverage (FVC) can visually represent ecological changes in a region. Based on MDO12A1 data to calculate FVC, we investigated the spatial and temporal variations of FVC in Qinghai Province from 2001 to 2015 and performed correlation analysis with the annual mean temperature and annual rainfall. The results indicate that the spatial changes in FVC in Qinghai Province increase gradually from northwest to southeast and are discontinuous due to topographic variations. In Qinghai Province, the area of higher FVC decreased by 0.69% over the past 15 years, while the area of medium FVC increased by 5.75%, and the area of lower FVC decreased by 5.06%. Changes in FVC in Qinghai Province are influenced by changes in rainfall and temperature. The average partial correlation coefficients of FVC with rainfall and temperature are 0.031 and 0.117, respectively, indicating that rainfall has a more significant influence on vegetation growth when the temperature remains constant.


Failaka Island is the second-largest and one of the most important islands of Kuwait from the point of view of tourism located in the north Arabian Gulf. It has a marina constructed in 1979 and managed by the Ministry of Communication (MOC) and a tourism enterprise, and is widely used for its ferry landing facility. The coastal waters around Failaka are turbid and current velocities tend to be as high as ~0.5 m/s during spring tide. The marina basin, with axial plan view dimensions of about 285 m by 260 m experiences shoaling of naturally flocculated fine (cohesive) sediment and coarse sand in the entrance channel and more generally in the southern half of the basin. A particularly noteworthy zone of heavy and visible shoaling is along the inner side of the south breakwater close to the entrance. The marina at Failaka Island is suffering from siltation and sediment deposing issues. This study was carried out numerically to assess the annual sedimentation, sediment direction, and longshore current from locations around the existing marina to help in a suggestion of the solutions to reduce the siltation and sediment deposing based on sediments transport direction on marina entrance. A newly developed numerical solution for annual longshore sediments transport was used to estimate the total sediment transport and its direction. The study shows that the annual sediment transport directions which affect the Fialaka marina entrance are coming from the south to north due to wave action.


Ever since the last years of World War I when the accumulation of rates on income flowing from one country to another reached in some cases more than ioo percent of the income, the United States has been a leader in unilateral, and later, bilateral measures for the prevention of international double taxation. As World War I was coming to a close in I918, Congress adopted the sound policy of recognizing the prior right of a foreign country in which income arises to tax such income and of granting a credit for the foreign tax levied in the country of source against the tax payable by the United States citizen, or resident, or corporation to the federal government. The credit for foreign taxes now found in Section 131 of the Internal Revenue Code1 has, through the years, been threatened with repeal; it has been encroached upon by amendments to the law and by court decisions, and has been in some cases limited and in others expanded in is application. Fortunately for our foreign trade and investments, the credit has survived and today it is in effect incorporated in our treaties for the prevention of international double taxation, concluded with France, Sweden, Canada, and England.


The current research aims to examine the relationship between the human resources management practices in force in the public enterprises in Benin and the indicators of the organizational climate. These practices RH are designed in this study as an ensemble of factors that exerts a positive influence on the performance if the organizational climate is on the same wavelength. To reach this objective, the research has been focused on the previous research works that resort the assumption that six (06) practices have an influence on the performance: recruitment, training, promotion, remuneration, communication, and assessment of the yield. This assumption has been testified on a sample of 400 employees owing to the method of questionnaire. The results obtained prove that the application without discrimination of these RH practices is at the same time source of satisfaction, cohesion and the reinforcement of the team spirit. The latter indirectly, limit the conflicting situations and influence positively the performance.


The association of urethritis, conjunctivitis and arthritis and cutaneous lesions is a syndrome not uncommonly produced by the gonococcus. Forty-seven cases 1 in which the gonococcus could not be found in relationship to this syndrome have been reported in the literature since 1912. The most recent article on this subject was one by Lever and Crawford, 1 who reviewed the subject from its dermatologic aspects. The triad of urethritis, conjunctivitis and arthritis, occurring in this order, in the absence of a gonococcic etiology, has come to be known as Reiter's disease. 2 The syndrome parallels gonorrheal infection so closely that suspicion of the gonococcus is difficult to dispel. Urethritis has been reported in all cases of this disease. The anterior and posterior urethra are involved, often with cystitis. It resembles the usual gonorrheal infection. For this reason it is difficult to recognize it apart from gonorrhea unless smears have been

Acceleration associated with mechanical vibrations on drilling rigs during drilling and in similar mining equipment have harmful effects on workers present at their work stations. This adverse condition coexists together with other numerous environmental factors characteristic for the activity of drilling equipment. Drawworks, combustion engines, mud pumps, electrical generators, shale shakers, pneumatic grinders are mechanisms creating different kinds of vibrations during their work. It happens, that vibration amplitude exceeds allowable values of obligatory standards or legal regulations, and puts workers at risk of health loss. In order to determine the magnitude of vibration, measurements and tests are performed periodically mainly at work stations. Whole body vibrations (WBV) (transmitted to the human body through his legs, pelvis, back or shoulders) and hand-arm vibrations (HAV) (acting through hands) have been measured and interpreted. The main parameters characterizing the harmful factors acting on workers, such as: permissible values of vibration acceleration, permissible exposure time have been calculated and compared with measured values. Ratios of measured vibration values to Occupational Exposure Limits (NDN) were evaluated. A comparison of the changes in the NDN index that took place in 2005–2016 at work stations for selected drilling equipment was made. The publication discusses the issue of mechanical vibrations occurring at work stations. Pilot vibration surveys were performed according to the requirements described in Polish regulations and appropriate EU documents. By comparing measured vibration values with OEL, the degree of their harmful effect was determined. In order to facilitate and accelerate calculations, a spreadsheet was prepared. Elaborated measuring and interpretation methods were implemented in the form of a spreadsheet and are currently used to evaluate mechanical vibrations in oil industry plants and in other similar industries.


This study aimed to identify which subset of CD34+ cells might be the most predictive of early and long-term hematopoietic recovery following autologous peripheral blood stem cell (PBSC) transplantation (PBSCT) in adult acute myeloid leukemia (AML) patients. The relationships between the number of 'mature' subsets of CD34+ cells (CD34+/CD33+, CD34+/CD38+, CD34+/DR+ and CD34+/CD90–) and 'immature' subsets of CD34+ cells (CD34+/CD33–, CD34+/CD38–, CD34+/DR– and CD34+/CD90+) and early and long-term hemoglobin, neutrophil and platelet counts were studied in a homogeneous series (for disease, pre-transplant chemotherapy, mobilization chemotherapy, conditioning regimen) of 26 AML patients after autologous PBSCT. Cell counts were performed before and after cryopreservation, but only after thawing were the cell counts used for correlation with early and long-term engraftment. The number of CD34+/CD38– cells infused correlated with the neutrophil (r = 0.88, p < 0.005) and platelet counts (r = 0.67, p < 0.05) at 12 months after PBSCT. This correlation was better than that for the total CD34+ cell dose at 12 months (r = 0.36, p = 0.09 for neutrophil count and r = 0.48, p = 0.06 for platelets count). The number of CD34+/CD90+ cells was also correlated with the platelet counts at 6 (r = 0.70, p < 0.05) and 12 months (r = 0.80, p = 0.005) after PBSCT. This correlation was better than the total dose of CD34+ cells at 6 (r = 0.31, p = 0.3) and 12 months (r = 0.48, p = 0.06) for the platelet counts. CD34+ subset analysis suggests that for early engraftment the total number of CD34+ cells infused is more strongly correlated than the CD34+ subsets, whereas the CD34+/CD38– and CD34+/CD90+ subsets may be associated with sustained long-term neutrophil and platelet engraftment. These findings may help to predict the repopulating capacity of PBSCs in AML patients after autologous PBSCT, especially when a relatively low number of CD34+ cells is infused.


Metabolic Acidosis. The infusion of sodium lactate is followed only slowly by a rise of bicarbonate ion concentration and change in pH, and therefore it is usually preferable to use sodium bicarbonate solution. The isotonic solution is necessary for dehydrated conditions such as diabetic coma. The most useful concentration is a 2·74% solution, which has twice the osmolarity of plasma. Under certain conditions, such as in cardio-pulmonary by-pass, more concentrated solutions can be used with safety.


The paper presents an overviw of the croatian- italian bilingual policy and the practical perspectives of formal and informal language use and ideology in the Region of Istria. The Statute of the Istria County and other legislative regulations will be put into relation with the educatonal practice in Italian schools, taking into account the language education policy profiles of the European perspectives for the promotion of plurilingualism and intercultural education, particularly in border areas. Beside a brief review of the major theoretical perspectives related to the current state of bilingualism in Istria (Milani Kruljac 1990, 1992, 2003 ; Scotti Juric 1998, 2004, 2005, 2007, 2008 ; Filipi 1987, 1988-89 ; Orbanic 1989, 1990-1991 ; Bogliun Debeljuh 1989, 1992 ; and so forth), the uses of languages in constant contact will be presented through the exeplified uses of Croatian and Italian standard languages, as well as the Istrovenetian dialect used in informal domains among croatian-italian bilingual/plurilingual speakers attending italian educational institutions. Linguistic strategies and typological features of mixed-language uses will be discussed, according to frequent interference and code-switching modes characterizing the diglossic stratification as appeals for discursive strategies with clear and distinct interactive pragmatic functions.


A tandem simulated moving bed (SMB) was developed previously for the purification of insulin from two impurities in two sequential steps. In this study, an efficient optimization tool based on the standing wave design is developed to find the optimal tandem SMB for insulin purification. Both system parameters (total number of columns, zone configuration, column diameter, and column length for each ring) and operating parameters (zone flow rates and switching time for each ring) are optimized to achieve the lowest purification cost. In the production range of interest, equipment cost dominates. For this reason, the optimal design has eight or fewer columns in each ring. The optimal design also has a small column length and a large column diameter, as the stationary phase for insulin purification is compressible and has a zone linear velocity limit. Splitting strategies and constraints on the column diameter and column length have significant effects on the optimal design. If there is a limit on the column ...


Iranian psychology students often face difficulties in understanding psychology texts in English. This can have an adverse effect on their opportunities of academic success. To help them overcome those difficulties, the current study investigated the effect of visual mnemonic support practice on students' reading comprehension. The participants of the present study were 55 Iranian psychology seniors chosen out of 71 students based on their PET language proficiency test scores. They were divided into two homogenous groups of experimental and control. The experimental group benefited from visual mnemonic techniques, including pictures and visualization. Open-ended questioning was used as a measure of reading comprehension. Results of Independent Samples Ttest revealed that the experimental group outperformed the control group. Pedagogical implications of visual mnemonic aids are also discussed.


Diary writing is often something that happens when the narratives by which we live break down. From 1985 until April 1986, while her mother was dying of Alzheimer's disease, Annie Ernaux kept not one journal, but two: Journal du dehors (1993) and the journal des visites, published as "Je ne suis pas sortie de ma nuit" (1997). While it might seem that this double diary practice enabled Ernaux to separate her inner concerns from her more public daily life, the fact that Journal du dehors draws simultaneously on several different generic conventions, among which are both the journal intime and the ethnographic log, and that Ernaux publishes the journal des visites as "Je ne suis pas sortie de ma nuit" undermines any attempt to account for this double diary keeping in terms of a private/public or personal/collective dichotomy. This article focuses on the work that is performed by this doubling of Ernaux's journal space. It argues that Journal du dehors is not merely the effect of disruption, but more specific...


Optical fiber communication technology is beneficial to satisfy today's increasing demands for high data rates. This need for higher data rates and bandwidth has driven the fast development of fiber optic communication technologies. But at the same time, some undesirable nonlinear effects in the optical fiber medium become noticeable at high power levels. These fiber nonlinearities affect the optical fiber communication systems. The light signal in Wavelength Division Multiplexing (WDM) system can be degraded due to nonlinear impairments in the fiber. So it has become necessary to study the nonlinear effects. In this paper, nonlinear effects called Self-Phase Modulation (SPM) and Four-Wave Mixing (FWM) are observed. Factors responsible for variations in SPM and FWM effects are analyzed using OptiSystem simulation tool.


We study the stability of composite fermion fractional quantum Hall states in Harper-Hofstadter bands with Chern number $|C|>1$. We analyze the states of the composite fermion series for bosons with contact interactions and (spinless) fermions with nearest-neighbor interactions. We examine the scaling of the many-body gap as the bands are tuned to the effective continuum limit $n_\phi\to 1/|C|$. Near these points, the Hofstadter model realises large magnetic unit cells that yield bands with perfectly flat dispersion and Berry curvature. We exploit the known scaling of energies in the effective continuum limit in order to maintain a fixed square aspect ratio in finite-size calculations. Based on exact diagonalization calculations of the band-projected Hamiltonian, we show that almost all finite-size spectra yield the ground state degeneracy predicted by composite fermion theory. We confirm that states at low ranks in the composite fermion hierarchy are the most robust, and yield a clear gap in the thermodynamic limit. For bosons in $|C|=2$ and $|C|=3$ bands, our data for the composite fermion states are compatible with a finite gap in the thermodynamic limit. We also report new evidence for gapped incompressible states of fermions in $|C|>1$ bands, which have large entanglement gaps. For cases with a clear spectral gap, we confirm that the thermodynamic limit commutes with the effective continuum limit. We analyze the nature of the correlation functions for the Abelian composite fermion states and find that they feature $|C|^2$ smooth sheets. We examine two cases associated with a bosonic integer quantum Hall effect (BIQHE): for $\nu=2$ in $|C|=1$ bands, we find a strong competing state with a higher ground state degeneracy, so no clear BIQHE is found in the band-projected Hofstadter model; for $\nu=1$ in $|C|=2$ bands, we present additional data confirming the existence of a BIQHE state.


Chemokines promote the delivery and proper organization of an integrin at the leading edge of migrating lymphocytes. Integrin Delivery Service Optimal immune responses depend on lymphocytes getting to the right place at the right time. Chemokines are secreted proteins that bind to cell surface chemokine receptors and act as the tracking signals for lymphocytes to follow to sites of infection or injury. Integrins are another type of cell surface protein that are important for lymphocyte activation and migration. Nishikimi et al. identified a mechanism through which the kinase Mst1 and the vesicle-associated protein Rab13 respond to chemokine signals by transporting integrins containing LFA-1 from the inside of lymphocytes to the plasma membrane at the leading edge of migrating cells. Rab13-deficient lymphocytes exhibited impaired migration in culture, and Rab13-deficient mice had smaller lymphoid organs than those of wild-type mice because of defective lymphocyte trafficking. In lymphocytes, the kinase Mst1 is required for the proper organization of integrins in the plasma membrane at the leading edge of migrating cells, which is critical for lymphocyte trafficking. We found a functional link between the small G protein Rab13 and Mst1 in lymphocyte adhesion and migration. In response to stimulation of T lymphocytes with chemokine, Mst1 promoted phosphorylation of the guanine nucleotide exchange factor DENND1C (differentially expressed in normal and neoplastic cells domain 1C), which activated Rab13. Active Rab13 associated with Mst1 to facilitate the delivery of the integrin LFA-1 (lymphocyte function–associated antigen 1) to the leading edge of lymphocytes. Delivery of LFA-1 involved the recruitment of myosin Va along actin filaments, which extended as a result of the localization of the actin regulatory protein VASP to the cell periphery through phosphorylation of VASP at Ser157 by Mst1. Inhibition of Rab13 function reduced the adhesion and migration of lymphocytes on ICAM-1 (intercellular adhesion molecule–1), the ligand for LFA-1, and inhibited the formation of a ring-like arrangement of LFA-1 at the contact sites between T cells and antigen-presenting cells. The lymphoid tissues of Rab13-deficient mice had reduced numbers of lymphocytes because of the defective trafficking capability of these cells. These results suggest that Rab13 acts with Mst1 to regulate the spatial distribution of LFA-1 and the motility and trafficking of lymphocytes.


The common attitude to study of Qian zhongshu and Ma yifu is not for founding a school and not playing master,which came from the ancient Chinese tradition of studying for self.


Lipases are particularly important because they specifically hydrolyze acyl glycerol, oils, which are of great interest for different industrial applications. Some halophilic microorganisms produced some lipases. Halophilic bacteria have greater ability to produce salt and thermo tolerant enzymes like amylases, proteases and lipases. Most industrial enzymatic functions may be stopped by concentrated salt solutions and high temperatures; therefore, halophilic enzymes that have optimal activity at a vast range of temperature, pH and ionic strength, would be considered as suitable biocatalysts in industrial processes. The aim of this study was to isolate and study the halophilic lipase producing bacteria from the Miankaleh Wetland. The lipase activity was measured using titrimetric methods. Three halophilic strains (AR11, AR18 and AR28) were isolated from the Miankaleh wetland and were screened for the production of hydrolytic enzymes and lipolytic activity. Among three isolates, one strain was selected for identification using the molecular methods and some morphological characteristics. The bacterium Halobacillus truperi AR11 with 1.82 ± 0.1 U/mL lipase activity was selected as the highest lipase producing isolate. Lipase enzyme produced by this potential isolate was also characterized for determining its optimal activity. Effect of different pH, NaCl concentration and temperature on lipase activity was determined. The optimum pH for AR11 was found to be 9, while the optimum temperature and NaCl concentration for lipase activity was found to be 45oC and 5 % NaCl, respectively. This is the first report of isolation and molecular identification of lipase producing halophilic bacteria from the Miankaleh wetland.

Abstract In their 2009 report 'Strengthening Forensic Science in the United States: A Path Forward' the National Academies of Science (NAS) called for the development of a body of research establishing the limits of the performance of forensic scientists on a range comparison tasks. The NAS proposed that this could be facilitated through collaboration between the forensic sciences and broader research communities. In this paper we outline a range of issues cognitive scientists routinely consider when designing human performance tests. In doing so the aim is to provide forensic scientists with tools to help avoid common research design errors while also laying a common foundation for further collaborations between cognitive and forensic scientists as sought by the NAS.


Both natural and anthropogenic processes are responsible for excessive organic loading of submerged soils, with detrimental environmental consequences. The often insufficient natural attenuation can be enhanced by exploiting microbial manganese cycles. This review describes how an anoxic oxidation of organic matter with concomitant reduction of MnO 2 can link up with a reoxidation of the resulting, soluble Mn(II) in oxic layers. The potentially attainable oxidation rates through these natural cycles are of the same order as the organic carbon accumulation rates. The microbiology and physiology of the responsible organisms are discussed, as well as examples of naturally occurring manganese cycles and the possibility to engineer this natural phenomenon.
