The review was limited to the socio-economic-demographic aging of the population of South Sumatra, which in terms of differences in change between the District / City, which consist of 14 districts / cities. Being old is a natural process that can not be avoided. Preparing for the elderly population with a population of productive in terms of health and confidence. Investment of human resources emphasis should be encouraged and demographic variables need special attention. Changes in these demographic elements have broad impact on changes in population age structure in each region, which in turn can affect socio-economic circumstances and political area. Change in these demographic elements also have a profound effect on population age structure changes south of Sumatra, which in turn can affect socio-economic circumstance and political southern Sumatra. Keywords: Population-Based Development, the elderly population

The algorithms for determining the first four moments, their standard deviations, asymmetry and excess coefficients of wind velocity components (radial Vr and orthogonal Vort components, absolute value of the horizontal wind Vh and its direction (phi) ) by the Volna-3 sodar are described. The quality of estimation of these moments heavily depends on the quality of sodar measurements of instantaneous radial components Vr(i) and the accuracy of determination of their centers of distribution. So, to reject possible anomalous values, the corresponding procedure of iteration censorship of data is applied to Vr(i) with the further use of the adaptive averaging procedure. For the Vort, Vh, and (phi) two methods of estimation are considered. The first method is based on calculation of their instantaneous values, and the further processing of Vort and Vh components is similar to that of the radial components Vr. The moments of (phi) are obtained using statistical methods. The second method is based on the use of pre-calculated moments of Vr and their additional statistical characteristics. To objectively estimate the degree of certainty of the obtained information, the point (standard errors) and interval (90% confidence intervals) estimates of random measurement errors are calculated.


Since 1982, the electoral fortunes of the SPD have followed a downward trend, accompanied by a pervasive malaise and uncertainty regarding coalitions with the Greens. The strategic choice before the SPD is mirrored by the analogous dilemma of the CDU/CSU with regard to the FDP. The problems of integrating the 'two or more SPDs' in a rapidly changing urban society are aggravated by the sectarian New Left in the big cities. Only a new consensus based on widely popular themes can lead the SPD back into power.


In this modern era of electronic technologies, all the appliances require a separate power supply. To overcome this drawback, the concept of a single converter with multiple power supply has been proposed. Furthermore, the proposed research work clarifies about multipurpose charger, which alters and uses a boost topology to supply different outputs as required for different applications. Proposed method consists of multiple PWM duty cycles to produce multiple regulated power supply voltages, and so it is also referred as multi power boost converter. It uses one converter for obtaining various outputs. For example, mobile, laptop, electric vehicle, or any other electronic appliances can be charged using multi power boost converter.


We investigate a downlink channel assignment scheme for multipoint communications and we propose a new simulcast-based dynamic channel assignment policy for both unicast and multicast connections in LEO satellite networks. In order to reduce co-channel interference power and to avoid intersymbol interference problem, our policy is combined with a power control algorithm. Performance evaluations show that our policy compared to other policies achieve bandwidth optimization and improves the quality of service since it reduces call blocking probabilities for both unicast and multicast connections.


Currently a resting electrocardiogram costs £35 through the Cardiac Risk in the Young programme. Variable penetrance for hypertrophic cardiomyopathy with obstruction means that one-off resting ECG screening will miss the commonest cause of sudden athletic death in people under 35 unless it is …


We have read the recent review [1] on the use of serotonergic drugs in functional gut disorders with great interest and would like to comment on two aspects that may confuse the readers involved in drug development in this difficult area.

First, Dr Spiller states that prolongation of the QT interval by cisapride is due to an action on cardiac 5-HT4 receptors. However, there is now consensus that the occurrence of QT prolongation and ventricular tachyarrhythmias such as torsades de pointes by cisapride is due to blockade of human ether-a-go-go-related gene K+ channels [2–5]. Cisapride may indeed trigger tachycardia and supraventricular arrhythmia through stimulation of atrial 5-HT4 receptors [6]. However, the incidence of the atrial arrhythmia is very low [7], probably because cisapride behaves as a partial agonist on the human atrium and because the density of 5-HT4 receptors in the atrium is low [8]. The lack of involvement of 5-HT4 receptors in generating QT prolongation is also supported by the failure of the selective 5-HT4 receptor antagonist {"type":"entrez-nucleotide","attrs":{"text":"GR113808","term_id":"238362519","term_text":"GR113808"}}GR113808 [9] to modify cisapride-induced action potential prolongation in guinea-pig isolated papillary muscles.

Thus, we may conclude that QT prolongation is not a class effect necessarily shared by all 5-HT4 receptor agonists and that it is possible to develop selective 5-HT4 receptor agonists with no effect on the QT interval: tegaserod may be an example [10]. In addition, it should be noticed that all 5-HT4 receptor agonists so far developed (including cisapride, prucalopride and tegaserod) are partial agonists, but only tegaserod is presented as such in Table 1 of Dr Spiller's paper.

Secondly, we would like to point out that buspirone and sumatriptan are both defined as 5-HT1P receptor agonists throughout the review, whereas buspirone is a 5-HT1A receptor agonist (and also a dopamine D2 receptor antagonist) [11] and sumatriptan is the prototype 5-HT1B/D receptor agonist [12]. Sumatriptan has been extensively investigated by Dr Tack's group [13, 14] and was found to have important effects on gastric tone and perception of gastric distension [14], but the receptors involved in mediating its effects are still a matter of debate. Therefore, the fact that 5-HT1P receptors are presented as potential therapeutic targets in functional gut disorders is misleading, all the more so because 5-HT1P receptors are not included in the official IUPHAR classification of serotonin receptors [12]. We are aware that the presence of 5-HT1P receptors is reported in enteric neurones [15], but the hypothesis that sumatriptan determines its gastric motor effects in vivo through these receptors still awaits confirmation by pharmacological studies with selective antagonists. It is noteworthy, however, that a preliminary report by our group [16] showed that the gastric motor effect of sumatriptan was blocked in vivo by {"type":"entrez-nucleotide","attrs":{"text":"GR127935","term_id":"238377770","term_text":"GR127935"}}GR127935, a selective 5-HT1B/D receptor antagonist.


The crystal of Ce5Ni2Si3 was prepared by the Czochralski method. The X-ray photoemission spectroscopy was measured for the valence band and the core levels. Based on the Ce(3d) doublet and its satellites a small value of the hybridization parameter of the f -states with the conduction electrons ∆ = 4 meV and the f -occupancy nf close to 1 were found. X-ray photoemission spectroscopy shows that the region between 0 and 3 eV is predominated by the Ni(3d) and Ce(4f) peaks. Some features of the multiplet structure of the Ce(4f) states are also visible close to the Fermi level.


Integrated circuit technology has been successfully applied to the design and fabrication of 0.5×0.5‐cm planar multijunction solar‐cell chips. Each of these solar cells consisted of six voltage‐generating unit cells monolithically connected in series and fabricated on a 75‐μm‐thick, p‐type, single crystal, silicon substrate. A contact photolithic process employing five photomask levels together with a standard microelectronics batch‐processing technique were used to construct the solar‐cell chip. The open‐circuit voltage increased rapidly with increasing illumination up to 5 AM1 suns where it began to saturate at the sum of the individual unit‐cell voltages at a maximum of 3.0 V. A short‐circuit current density per unit cell of 240 mA/cm2 was observed at 10 AM1 suns.


Article history: Received 8 February 2019 Received in revised form 21 May 2019 Accepted 30 May 2019 As a result of rapid urbanization worldwide, the vegetation areas, grasslands, and forests were replaced with construction and buildings. It is known that roads, pavements, concrete surfaces and walls all absorb sunlight during daytime and reflect heat as heat waves at night. It is clear that green areas have a significant role in urban life. Most of the research conducted in this field has shown that green areas mitigate the urban heat island, improve air quality, decrease noise and manage stormwater within the cities. Green spaces, green roofs, green walls, street trees, and water sources all have a positive impact on urban temperatures. Unfortunately, due to the rapid expansion in urbanization activities in Kyrenia, northern Cyprus, urban green spaces are decreasing at an alarming rate. Therefore, two different experimental works have been applied within the region; the first of these studies has been conducted on Ziya Rızkı Avenue. In this first study, temperature differences of shading with and without trees were measured. Additionally, the second study focused on the temperature differences between urban and rural areas. In the second research, urban and rural spaces were measured concurrently over a period of one month. It was proved by both studies that green spaces mitigate urban temperatures. Therefore, research results should be taken into consideration and architects, urban designers and planners should pay attention to green areas, street trees, parks, green roofs, and vertical green system establishments.

Spot blotch disease caused by Bipolaris sorokiniana (Sacc.) shoem. is one of the most destructive diseases of wheat (Triticum aestivum L.) in plain areas of Nepal. A laboratory experiment was conducted to evaluate the antagonistic activity of seven test Trichoderma isolates obtained from the soil sample by employing dual culture method against spot blotch pathogen of wheat Bipolaris sorokiniana at Plant Pathology Division, Nepal Agriculture Research Council, Khumaltar, Nepal. The experiment was laid out in a Completely Randomized Design (CRD). The result revealed that all Trichoderma isolates showed control over the pathogen. Isolate T517 stands out to be the most effective one giving 67.81% mycelial growth inhibition but isolate T528 was the least effective. Native Trichoderma can have significant biocontrol potential and may provide an effective solution against plant fungal diseases.


Summary The therapeutic effects of sodium sulfadiazine upon Amblystoma embryos, following surgical interruption of the central nervous system, are described. Embryos which may undergo 100% mortality when sterile technic is not employed, will survive when treated for 2 days with a 1% aqueous solution of the drug. There is no evidence of any toxic effect. Treated embryos undergo normal development and at a rate parallel with control embryos kept at the same temperature. Minimum concentrations of the drug as well as minimum length of treatment necessary to insure survival remain to be determined.


SUMMARY. Scales of several members of the Chrysophyceae (family Synuraceae) were examined from a core of the recent sediments of Hall Lake, Washington, in conjunction with a study of fossil diatoms. Both types of microfossils revealed communities changing with the historical development of the lake. Increases in planktonic diatoms and in two species of Mallomonas occurred about the time of European settlement. Several acidophilous species among the Chrysophyta disappeared with the establishment of a sawmill and meromictic conditions in the lake. When extensive road construction around the lake ended the period of meromixis, the ratio of Synuraceae, in general, to diatoms, declined. Besides the change in ratio of Synuraceae to diatoms there was a change in the composition of the community of Synuraceae at that time. Species of Synura that had been rare before became the most abundant, and Mallomonas became relatively rare. Throughout the recent history of the lake the dominant Synuraceae seemed to respond more strongly to disturbance around the lake than the most abundant diatoms; thus, scales of Mallomonas, Synura, and other Synuraceae are valuable microfossils for paleolimnological studies.


The use of fullerene as acceptor limits the thermal stability of organic solar cells at high temperatures as their diffusion inside the donor leads to phase separation via Ostwald ripening. Here it is reported that fullerene diffusion is fully suppressed at temperatures up to 140 °C in bulk heterojunctions based on the benzodithiophene‐based polymer (the poly[[4,8‐bis[(2‐ethylhexyl)oxy]‐benzo[1,2‐b:4,5‐b′]dithiophene‐2,6‐diyl][3‐fluoro‐2‐[(2‐ethylhexyl)carbonyl]‐thieno[3,4‐b]thiophenediyl]], (PTB7) in combination with the fullerene derivative [6,6]‐phenyl‐C71‐butyric acid methyl ester (PC70BM). The blend stability is found independently of the presence of diiodooctane (DIO) used to optimize nanostructuration and in contrast to PTB7 blends using the smaller fullerene derivative PC70BM. The unprecedented thermal stability of PTB7:PC70BM layers is addressed to local minima in the mixing enthalpy of the blend forming stable phases that inhibit fullerene diffusion. Importantly, although the nanoscale morphology of DIO processed blends is thermally stable, corresponding devices show strong performance losses under thermal stress. Only by the use of a high temperature annealing step removing residual DIO from the device, remarkably stable high efficiency solar cells with performance losses less than 10% after a continuous annealing at 140 °C over 3 days are obtained. These results pave the way toward high temperature stable polymer solar cells using fullerene acceptors.


Today, computer science graduates are well-sought by employers. A computer science education will furnish you with many skills that may be applied to a number of careers. However, as always, there are portions of the traditional curriculum that can be improved. This paper summarizes and justifies the author's opinions on how computer science curricula may evolve. She hopes to continue discussions in this area throughout her career, because discussing these issues with other interested professionals is the way to find the best path.


In thermal power plants, the over-speed protection control (OPC) is one of the most important functions in Digital Electro Hydraulic system (DEH), the objective is to inhibit the turbine speed soaring and protect the generator's safe. However, if the OPC parameters selection is irrational, the isolated power grid which is tripped from the bulk power grid would appear the phenomenon of "power or frequency oscillation" at load rejection condition. If the oscillations are not disappeared in time, the whole grid would be collapsed, the isolated power grid is vital for resuming main grid after sudden unpredictable mistake. The mathematical model for isolated grid stability research is established in this paper, the Simulate reproduce power oscillations at the accidents. Several improvement proposals of OPC control logic are also discussed, the results show that increasing the OPC action speed point and removal speed point is benefit for preventing the grid oscillation. It's significant for guiding adjusting the OPC parameters to ensure the isolated power grid safe and stable.

The article analyzes the infiltration, operational technique for obtaining data, from the viewpoint of the police officer that, to enter (to be a part of) a criminal organization, acts as a criminal. Addressing first the appearance of this new type of crime and special investigation techniques, the paper aims to explain the legal uncertainty surrounding the police officer because the homeland law does not regulate this issue clearly, forgotten issues essences that relate to the role of the police officer before, during and after implementation of the measure. Moreover, the study outlines in detail the features that characterize the infiltration, undoing a mess that makes this applicant in relation to the "cover-story". Accordingly, the test shows that, even before the enforcement action by the State, the development of valid standards, "rules of the game", is a sine qua non condition for building a Democratic State of Law, because the search for evidence is not at any cost. If on one hand are the rights of the researcher, in the other are the rights and guarantees of the police officer.


Introduction In the area of environmental psychology, time and the temporal perspective have often been used as an overarching framework to explain or predict environmental outcomes. This study aims to introduce a new Time Importance Scale (TIS) based on the attitude strength theory and to assess its nomological validity in comparison with the more established Temporal Focus Scale (TFS) in the context of consumers' willingness to pay more for environmentally friendly products. The new TIS scale is short and simple to manage. Method The study proposes competing plausible structural models testing alternative relationships between future time perspective (FTP) and environmental values using a nationwide representative survey sample of 633 Norwegians. Results The results confirm the convergent and discriminant validity of the new TIS scale. However, the direct association between the TIS scale and willingness to pay for environmentally friendly products is weak or non-significant depending on the alternative models used to validate the nomological validity. Discussion The new TIS scale provides evidence of a possible causal chain, FTP → environmental values → willingness to pay, with strong associations between the present TIS and hedonic values and between the future TIS and biospheric values. Environmental values are activated by FTP. In most cases, the new TIS outperforms the established TFS in nomological validity. Future research should validate our findings in experimental trials to demonstrate more substantial causal relationships.


137 Cs and 40 K uptake by vegetable plants was examined in a number of places in Belarus located at the outer perimeter of the 30-km Chernobyl zone. Differences in the uptake of 40 K and 137 Cs by plant species were not found to be related to the radionuclide content in the soil, but are essentially related to plant features. Vegetable plants were found to accumulate 40 K more actively than 137 Cs. For 40K and 137 Cs, the ratio of the nuclide content in plants to their content in soil shows a tendency to decrease with increasing nuclide concentration in soil.


Abstract Two new families of exact coherent states are found in plane Poiseuille flow. They are obtained from the stationary and the travelling-wave mirror-symmetric solutions in plane Couette flow by a homotopy continuation. They are characterized by the mirror symmetry inherited from those continued solutions in plane Couette flow. The first family arises from a saddle-node bifurcation and the second family bifurcates by breaking the top–bottom symmetry of the first family. We find that both families exist below the minimum saddle-node-point Reynolds number known to date (Waleffe, Phys. Fluids, vol. 15, 2003, pp. 1517–1534).


We report numerical results for the single-hole properties in the t-J model and the strong-coupling approximation to the Hubbard model in two dimensions. Using the hopping basis with over ${10}^{6}$ states we discuss (for an infinite system) the bandwidth, the leading Fourier coefficients in the dispersion, the band masses, and the spin-spin correlations near the hole. We compare our results with those obtained by other methods. The band minimum is found to be at (\ensuremath{\pi}/2,\ensuremath{\pi}/2) for the t-J model for 0.1\ensuremath{\le}t/J\ensuremath{\le}10, and for the strong-coupling model for 1\ensuremath{\le}t/J\ensuremath{\le}10. The bandwidth in both models is approximately 2J at large t/J, in rough agreement with loop-expansion results but in disagreement with other results. The strong-coupling bandwidth for t/J\ensuremath{\gtrsim}6 can be obtained from the t-J model by treating the three-site terms in first-order perturbation theory. The dispersion along the magnetic zone face is flat, giving a large parallel/perpendicular band mass ratio.

The general purpose of this paper was to investigate the particular situation of the state of Minas Gerais, in the contexto of the new national logistic perspective, relatives to selected investments in the systems of transportation in areas of the Brazilian cerrado. The nonlinear model allocated flows of soybean among producing regions and ports, considering minimized cost of transport routes, considering some modals. In the case, the Port of Vitoria (Center-East Corridor) was not sensible to the implantation of the transport systems, therefore it only reacted to the additions in the exported volumes. This implies the urgency of attention to the effective competition with the Sao Paulo (Port of Santos), that had expanded its area of influence for regions that could be being taken care of for the Center-East Corridor and the necessity to approach the strategical character of the investments in the transport systems (improvements in the highways, expansion of the railroad), as well as one better knowledge of the requeriments of the shippers, that can have significant regional impacts in the intraregional integration with the Triângulo Mineiro and areas under influence of the Sao Francisco Waterway.


Multizone selective production testing of a gas well is a time consuming and costly operation. A Khuff formation is a High Pressure High Temperature (HPHT) and high flow rate gas reservoir with the presence of H2S and C02. Traditionally, the multizone zone selective production testing operations for Khuff gas wells were performed using conventional methods. The use of Coiled Tubing (CT) on Khuff gas wells was limited only to displacing wells to diesel prior perforating the Khuff reservoir. This paper describes ADMA-OPCO experience to utilize a High Pressure Coiled Tubing (HPCT) package for the first time in Abu Dhabi and Offshore the Arabian Gulf to perform the different operations involved in the multizone selective production testing of a gas well with the objectives of safely reducing the operating time and costs.


Abstract : There has been significant change in land warfare as ground forces have simultaneously entered a network-centric age, an era of insurgency, and encountered changed players in the international system. To adapt to these changes, both industry and the military evolved in both requirements determination, development of new products, and rapid modifications of existing vehicles. It is the evolved military ground equipment required in these theaters, and industry's role in provisioning them, that motivated this evaluation of the LCS industry. The Land Combat Systems Industry Study spent four months visiting manufacturers, policy makers, and depots to compile this report. Over the course of the study while researching the Structure, Conduct and Performance of the industry, the seminar developed the following Major Findings on strategic issues identified and reported in report sections that follow below. 1. Reform the requirements generation process to become more responsive and agile in the face of changes in enemy tactics and evolving US tactics. 2. Partnerships between firms and within firms (labor and management) are crucial to agile response to changing requirements. 3. There was sufficient surge capacity within the LCS industrial base to meet the demands of the campaigns in Iraq and Afghanistan. 4. Public-Private Partnerships and joint-ventures were expanded during the last 4-6 years illustrating the globalized nature of the industry and the evolving role of government-owned depots in production of combat and tactical vehicles. 5. Every vehicle is now a "combat vehicle" that sports a measure of armor protection and weapons. 6. Information technology is expanding into the ground vehicle fleet at an exponential rate; including situational awareness, C2, and electronic-counter measures systems.

We investigate physical-layer security (PLS) for multi-antenna and multi-relay networks with transmit beamforming and relay selection under feedback delay. The connection outage probability (COP) and secrecy outage probability (SOP) are derived to evaluate the reliability and security. Besides, we introduce a novel definition of the reliable-and-secure probability (RSP) to combat the correlation between COP and SOP introduced by the corporate source-relay link. Based on this, to measure the overall efficiency of the system achieving reliable and secure transmission, we further investigate the modified secrecy throughput performance and develop the optimal design of secrecy codeword rate setting to maximize the secrecy throughput. Numerical results verify the analysis and suggest the importance of secrecy codeword rate setting on the security performance.

This chapter inquires into four very different Australian middle-school classrooms where teachers are innovating their practices and developing new approaches to aspects of English curriculum. These classrooms from diverse settings (one middle-class urban, one elite private inner urban, one regional disadvantaged, one middle-class regional) have all taken imaginative leaps and reworked their curricula to put the students' needs at the centre. At one school, Year 8 students design, make and play their own computer games, at another Year 6 students script, design, craft and shoot their own claymation film; at another, Year 9 students use videogames as texts in their literature studies; and at another, a group of Year 6 students work with a theatre company and their teachers to rework Shakespeare into a contemporary, accessible, enjoyable performance. The chapter considers how in each case these different approaches engage and extend the students in meaningful and relevant ways. The chapter includes a mix of teacher and student interview data, principal data and teacher writing. The chapter investigates how each of these projects worked to achieve its aims and discusses how the single national curriculum might be re-envisioned in local contexts.


This paper presents the effect of laminated aluminium-steel panel with different configurations in a high-speed impact test. Layering aluminium plate with high strength steel has become an interest in reducing the overall density of armour vehicle body while improving the ballistic resistance. Different layering configurations differ in laminated panel performance. Two layering configurations of double-layered panel achieving 25% of existing panel weight reduction were tested using experiment and computational method to investigate their behaviours when impacted with 7.62-mm full metal jacket at velocity range of 800–850 m/s. The ballistic performance of each configuration plate in terms of ballistic limit velocity, penetration process and permanent deformation was quantified and considered. Laminated panel with aluminium as the front layer reduced the ballistic performance of existing panel to 50% and the other panel maintained its performance. Thus, the laminated panel with aluminium as the back layer can be used in designing a protective structure for armoured vehicle while maintaining the performance of the existing vehicle in achieving weight reduction.


THE ARTICLE by Averill and colleagues (2016) raises a number of interesting questions about the use of outcome measures to evaluate quality of care, and then about the use of outcome measures in various forms of pay-for-performance programs, including those that explicitly involve some form of "pay-for-outcome." There is little question about the potential value of focusing quality measurement and financial programs more heavily on outcome measures and less on process measures. The key points in that argument have been summarized by Averill and colleagues and in other articles in this issue, and do not need to be repeated here. As is almost always the case in health policy discussions, though, the "devil is in the details," and there are indeed many details or questions to be resolved before public and private P-4-P programs can move significantly to an emphasis on outcome measures. The Averill article presents a set of simulation analyses on the basis of the proposed inpatient complication payment section of the "Incentivizing Health Care Quality Outcomes Act of 2014" (H.R. 5823 in the 113th Congress). In the proposed legislation, hospital payments would be adjusted on the basis


This paper presents an analytical model to evaluate the inter-turn short-circuit current in a Fault Tolerant Permanent Magnet Synchronous Machine (FT-PMSM) for different winding configurations. By evaluating slot-leakage and air-gap fluxes, the inductance of both healthy and faulty parts of the phase winding, as well as the mutual inductance between them, can be determined for any position and number of the shorted turns. Using these inductances, the short-circuit current is determined. The proposed model is verified with finite-element analysis and validated experimentally. It will be shown that the magnitude of an inter-turn short-circuit current depends on both the number of shorted turns and their position in the slot. A new concentrated winding configuration with vertical plate conductors in the slot is proposed. The measured short-circuit inductance shows that this winding can inherently limit the short-circuit current and reduce its dependence on the position within the slot.


Predictions of global crisis due to the earth's oil running out are probably premature, Russ Swan and MAlak Hamdan discover as they peer down a few boreholes.


We introduce a variant of Martin's axiom, called the grounded Martin's axiom, or grMA , which asserts that the universe is a c.c.c. forcing extension in which Martin's axiom holds for posets in the ground model. This principle already implies several of the combinatorial consequences of MA . The new axiom is shown to be consistent with the failure of MA and a singular continuum. We prove that grMA is preserved in a strong way when adding a Cohen real and that adding a random real to a model of MA preserves grMA (even though it destroys MA itself). We also consider the analogous variant of the proper forcing axiom.


Several issues and questions are associated with transmission of disease during air travel: 1. Widespread geographic movement of infected individuals to new communities, 2. Spread of disease to fellow passengers during the flight, 3. The types of pathogens primarily associated with disease transmission on airplanes, 4. Understanding the level of risk associated with air flight, and 5. Implementing sound and effective policies to prevent disease transmission during air travel. Quantitative microbial risk assessment (QMRA) is an approach that can be used to address these issues. QMRA as an integrated science is expanding and following a National Academies' approach. It is now possible to address the hazards and model exposures and, via a dose–response relationship, characterize the risk to a greater confidence level than was previously possible.


The limiting absorption principle is used to solve the scattering problem of time harmonic acoustic waves by penetrable objects in Sobolev spaces. The method is based on integral representation of the solution using the Green's kernel of the Helmholtz equation.


In previous work [1] we compared three time series visualization techniques (colorfields, horizon graphs, and line charts) in small multiples [2], in order to determine if the time series results returned from automatic similarity measures are perceived in a similar manner, irrespective of the visualization technique. Our results indicated that the notion of similarity is visualization dependent. In that first study, our colorfields implementation used a naive RGB color interpolation between red and blue hues. In this research report we describe a follow-up experiment, comparing this simple RGB interpolation to one that is perceptually uniform (CIE L*a*b*), in order to understand if the choice of color interpolation plays a role in the perception of similarity.

The erythrocyte, plasma and brain cholinesterase (ChE) activities of male rats and mice were determined using a simple colorimetric micromethod. In the normal male mice, the plasma ChE activity was 2.3 times higher than that of the erythrocyte. On the contrary, in the normal male rats, the erythrocyte ChE activity was 2.3 times higher than that of the plasma. The brain ChE activity was similar between rats and mice. The erythrocyte, plasma and brain ChE activities were decreased in both rats and mice exposed to diazinon and, however, this enzyme inhibition was most remarkable in the plasma of mice.

Normal Adrenal Function Cushings disease results from overproduction of a hormone called cortisol by the adrenal gland. The clinical signs noted are directly caused by excess cortisol. Indeed, normal dogs receiving steroid medications can develop the exact same clinical signs noted in dogs affected with Cushings disease. Cortisol production by the adrenal glands in normal dogs is controlled by the pituitary gland. The pituitary gland is located at the base of the brain and is also called the master gland. The pituitary gland produces ACTH which stimulates the adrenal glands to produce cortisol. Cortisol levels in the blood are detected by the pituitary gland. When blood levels are adequate, the pituitary gland decreases ACTH release and adrenal cortisol production decreases. This process serves to prevent insures that there are adequate, but not excess cortisol levels in the blood. This system is analogous to a home heating system where the thermostat (analogous to the pituitary) senses air temperature (analogous to cortisol level) to control the furnace (analogous to adrenal glands) to insure adequate but not excessive heating. Control of the adrenal glands in normal dogs is summarized below:


Molybdenum disulfide (MoS2) has been actively explored as a direct bandgap semiconductor in the monolayer (ML) limit for various applications due to its prominent physical properties and stability. In order to broaden its application range further, diverse treatments have been developed to modulate the properties of ML-MoS2. The native point defects, such as S vacancies, are known to activate surface charge transfer doping in ML-MoS2. Unlike conventional semiconductors, ML-MoS2 shows distinct excitonic transitions that can be exploited for controlling its optical, optoelectronic, and electric characteristics via coupling with defect-driven doping. Here, the ambient photoluminescence (PL) of ML-MoS2 could be increased by ~1500% at the center of focused-laser irradiation (FLI). Expectedly, the PL intensity varied spatially along with exciton–trion transitions across the irradiation spot due to the Gaussian profile of laser intensity. Then, nano-Auger electron spectroscopy (n-AES) revealed that the spectral fraction of exciton PL increased by ~69.2% while that of trion PL decreased by ~49.9% with increasing S deficiency up to ~13.4 ± 3.5%. Cryogenic PL and field-effect transistor experiments were also performed to understand the defect-related phenomena comprehensively. This novel experimental combination of FLI with an n-AES probe provides a facile, effective, and cost-efficient approach for exploring defect effects in two-dimensional structures.


This paper reviews grounds for just compensation and the market value standard in compulsory land acquisition, and then identifies limitations in the Korea's practices on compensation appraisal. In addition, the actual compensation level in Korea is empirically examined using available data. Results show that the appraisal of land compensation tend to fall short of the level of market-value-based compensation. The main reasons in terms of methods are two-fold. First, compensation is calculated on the basis of Officially Assessed Land Prices (OALP), which is estimated to be 40~50% of observed market price. Second, the compensation amount is set at the 'past' and not the 'current' market value by excessively excluding development surplus arising from the project to be promoted. As an ultimate remedy, this paper discusses a change in land compensation appraisal method, that utilizes market transaction prices more directly rather than relying on the OALP. As a supplementary measure in the transition period, an institutional framework is recommended to allow active adjustments to the primary compensation appraisal according to circumstances of the target land.

The study scrutinizes the rationale behind higher education policy change in England and Japan, giving attention to stakeholders' perspective and legitimacy, policy network, and policy sphere. It argues that change in higher education policy in England and Japan towards being more market-oriented in the 1980s (England) and the 1990s (Japan) can be commonly explained by the government's application of neo-liberal policy. The details in the political rationale for such policy change differ between the two. In England, change in the Government's values and perspective caused the policy change, while in Japan, enlargement of the policy sphere by incorporating non-education sub-government in the policy-making structure and the conflict and compromise between neo-liberal and anti-neoliberal groups resulted in the Government's policy change. The methods of data collection applied in the study were documentation and semi-structured interviews with selected stakeholders involved in the two higher education systems. The study suggests that not only change in the main stakeholders' values but also that in the policy network is significant in policy change.

The clear vision of what it means entrepreneurship and recognition of the role of the entrepreneur is very important to start the entrepreneurial process, as doing small business requires motivation, commitment, responsibility, skills and above all confidence. When these attributes will be connected to each other increases the level of preparedness of prospective entrepreneurs to enter into a business. In economics, entrepreneurship combined with land, labor, natural resources and capital can produce profit. It is a process of identifying opportunities in the market place, arranging the resources required to pursue these opportunities and investing the resources to exploit the opportunities for long term gains. In fact, entrepreneurship is a tool to transform the personal and organizational visions into plans and plans into reality. The capacity and willingness to develop, organize and manage a business venture along with any of its risks in order to make a profit.Entrepreneurship is concerned with making dynamic changes in the process of production, innovation in production, new usage for materials etc. It is a mental attitude to take calculated risks with a view to attain certain objectives. It also means doing something in a new and better manner. The most obvious example of entrepreneurship is the starting of new businesses. It is always associated with innovation and involves allocation of resources in the points where they give greater effect.


In this paper, the rather complex three-dimensional (3D) fatigue crack growth behaviour in a single-edge notched (SEN) specimen with an inclined plane of the initial crack under torsion loading is investigated with the aid of ADAPCRACK3D programme and by application of a recently developed 3D fracture criterion. It will be shown that the computationally simulated results for fatigue crack growth in the FE model of the specimen are in good agreement with experimental findings for the development of spatially twisted and warped crack faces in the real laboratory test specimen. Consequently, also for this case with a rather complex 3D crack growth behaviour, the functionality of the ADAPCRACK3D programme and the validity of the proposed 3D fracture criterion can be stated.


In this paper, firstly, the equilibrium solubility product formula of MoC with NaCl type cubic crystal structure in ferrite has been deduced by thermodynamic method, according to the free energy change of molybdenum and carbon dissolved in ferrite and the formation energy of MoC. On the basis of deducing activity coefficients of Mo in iron, the solubility product formula of MoC in austenite has been obtained according to the relationship of solubility product of MoC in austenite and ferrite. Finally, the solubility products for MoC and NbC in iron are compared. The solubility product formulae of MoC deduced would play an important role in related theoretical research and practical production.


Patients consult different private healthcare practitioners (PHP) due to the uniqueness of their illnesses and need for different specialisation. However, patient's health records are stored across autonomous systems of these different PHPs, leading to the establishment of heterogeneous health records. Consequently this creates a challenge of information sharing among PHPs. This study argues that these challenges are attributed to the non-integrated healthcare systems among PHPs and thus causing delay in treatment of patients. The study employs multiple case approach, using the semi-structured interview technique to investigate how health records are stored and shared amongst PHPs. The data collected was interpretively analysed to gain better understanding of the manipulation of patient's health record. According to the study findings, majority of PHP do not invest in IS and information sharing amongst PHPs is conducted manually. Sharing of medical records manually is challenging and is threatened by issues such as data theft and sabotage. In this study, an integrated architecture to guide the management of healthcare heterogeneous data among healthcare practitioners is developed.


In this paper, the problem of designing distributed LQR for multi-agent systems is considered when the states are not available for the control purpose. Two types of distributed observer-based LQR controller are developed with local observers and distributed observers. The design procedure provides a systematic way to construct control and observer gains that guarantee stabilization by solving two low-dimensional algebraic Riccati equations (ARE). The control and observer gains are designed in separation mode and they are decoupled from the communication graph structure. The effectiveness of this method is demonstrated by an example.

We have investigated the magnetoelectric coupling in the lone pair containing piezoelectric ferrimagnet Cu(2)OSeO(3). Significant magnetocapacitance develops in the magnetically ordered state (T(c) = 60 K). We find critical behavior near T(c) and a divergence near the metamagnetic transition at 500 Oe. High-resolution x-ray and neutron powder diffraction measurements show that Cu(2)OSeO(3) is metrically cubic down to 10 K but that the ferrimagnetic ordering reduces the symmetry to rhombohedral R3. The metric cubic lattice dimensions exclude a magnetoelectric coupling mechanism involving spontaneous lattice strain, and this is unique among magnetoelectric and multiferroic materials.


Laboratory methods for evaluating soil mixes for potting media are proposed, and measurement values from laboratory-compacted smaples are correlated with equivalent ones made under actual use of the mixes in gallon-sized soil containers in greenhouse conditions. Details are given of the materials and methods, and tables are presented which show the particle size distributionof the three soils (used in preparation of the soil mixes), the influence of various amendements on water retention and on saturated water conductivity, and comparison of the bulk-density and water-storage properties measured on laboratory-compacted cores with the same mixes in greenhouse. The study indicates that values of bulk density and hydraulic conductivity for compacted samples appeared to have usefulness in predicting these properties for the mixes in use. Water retention expressed as water released between 0 to 10 cb suction was not significantly correlated with this property by the use of root-extraction techniques. Water released by the soil to the root system over the range from 0 to 30 cb suction appeared to be a good index for evaluating soil mixes in relation to irrigation management. A safe irrigation program for potted plants should be based on irrigating when tensiometer readings reach 30 cb.

The objective of the publication is to investigate what are the daily characteristics of media consumption of Vilnius Ukrainian national community and how do these characteristics vary on the case of the War in Ukraine as well as the role of the media in shaping the political identity and opinion of Vilnius Ukrainian national community. The tasks of analysis: to clarify how Vilnius Ukrainian national community uses the media; to analyse how the consumption of the media of Vilnius Ukrainian national community vary on the case of the War in Ukraine; to clarify how media contributes to the shape of political opinion of Vilnius Ukrainian national community; Having analysed the academic literature and done the quantitative and qualitative researches, it was concluded that the characteristics of media consumption of Vilnius Ukrainian national community are typical to the characteristics of media consumption of national communities that form their identity in contemporary and global media surroundings. Vilnius Ukrainian national community consumes media in Lithuanian, Ukrainian, English and Russian. This proves why the political identity of contemporary national communities is rotational. The political identity of contemporary national communities that live in European countries as well as Ukrainian national community is related not with a particular country but with values of a democratic government. When the War in Ukraine started the need of information in Vilnius Ukrainian national community increased. The need of the information of Ukrainian media increased while the information of Lithuanian media was consumed to get in touch with the daily news related with the War in Ukraine. This indicates that Vilnius Ukrainian national community uses the information of different countries for different purposes.


This research is in the form of experimental research. The purpose of this study was to examine and see the effect of applying the ASSURE model and prior knowledge on the results of Simulation and Digital Communication subjects at the SMK. The population involved in this study were students majoring in Computer and Network Engineering class X SMKN 3 Pariaman, where class A was the experimental class and class B was the control class.

We deal with a backward problem of determining the initial function using final observations for the multi-term time fractional diffusion equations. The backward problem is of instability, and it is uniquely solvable based on the solution's expression of the forward problem and estimation to the multivariate Mittag-Leffler function. From view point of optimality, solving the inverse problem is transformed to minimizing an error functional, and existence of a minimum to the functional is obtained by continuity of the solution operator on the unknown. Furthermore, the homotopy regularization algorithm is introduced to solve the backward problem and numerical inversions with random noisy data are presented.


The effect of molecular weight of poly(L-lactic acid) on the stereocomplex formation between poly(L-lactic acid) (PLLA) and poly(D-lactic acid) (PDLA) was investigated. Films of 1:1 blend were prepared from PLLA with molecular weight of 125, 180 and 209 kg/mol and PDLA with molecular weight of 150 kg/mol by a solution cast method. Thermal properties, crystalline structure and mechanical properties were measured by differential scanning calorimetry (DSC), wide-angle X-ray diffraction (XRD) and tensile testing. Blending lowest molecular weight PLLA (Mw 125 kg/mol) with PDLA showed highest stereocomplex formation with melting temperature more than 50°C compared to that of homocrystallites. As the molecular weight of PLLA became higher, the stereocomplex formation was lower. Films with higher stereocomplex formation also had higher mechanical properties.


The mutton sheep breeding industry has transformed significantly in recent years, from traditional grassland free-range farming to a more intelligent approach. As a result, automated sheep face recognition systems have become vital to modern breeding practices and have gradually replaced ear tagging and other manual tracking techniques. Although sheep face datasets have been introduced in previous studies, they have often involved pose or background restrictions (e.g., fixing of the subject's head, cleaning of the face), which restrict data collection and have limited the size of available sample sets. As a result, a comprehensive benchmark designed exclusively for the evaluation of individual sheep recognition algorithms is lacking. To address this issue, this study developed a large-scale benchmark dataset, Sheepface-107, comprising 5350 images acquired from 107 different subjects. Images were collected from each sheep at multiple angles, including front and back views, in a diverse collection that provides a more comprehensive representation of facial features. In addition to the dataset, an assessment protocol was developed by applying multiple evaluation metrics to the results produced by three different deep learning models: VGG16, GoogLeNet, and ResNet50, which achieved F1-scores of 83.79%, 89.11%, and 93.44%, respectively. A statistical analysis of each algorithm suggested that accuracy and the number of parameters were the most informative metrics for use in evaluating recognition performance.


In previous work on the vibrational spectrum of simple lattice models, it has been shown (Blackman 1937) that the spectrum becomes anomalous when special values are chosen for the force constants entering into the description of the model. As an example we may take the case of a square lattice of lattice distance d containing one particle per cell, in which the force constants α (for particles at a distance α) and γ (for particles at a distance d √2) were used. When γ / α tended to zero it could be shown that the spectrum changed from the two-dimensional to that of the linear chain. A similar result holds in the corresponding three-dimensional case. Although one would not expect any actual crystal to correspond to a limiting case (it would not be stable) it is conceivable that there should be crystals which approach the limiting case. In all cases which have hitherto been discussed, the anomaly is associated with the behaviour of the low-frequency end of the spectrum. This suggests that one could trace the effect to some property of the elastic continuum. An examination of the lattice mentioned above, for which the elastic continuum has two elastic constants c 11 and c 12 = c 44, shows that the transition to the limiting case ( γ / α = 0) can be put in the form c 44/ c 11 → 0.


Summary The study compared antineoplastic effects of combined methotrexate and 5-fluorouracil therapy on LI210 lymphoid leukemia in mice according to the schedule of treatment. Methotrexate was administered at doses of: LOw.. 0.5 LOw. 5-Fluorouracil was administered at doses of: 0.2 LOIO, 0.1 LOw, 0.02 LOro. The parameters characterizing the efficacy of the therapy were survival time of mice inoculated with LI2l0 leukemic cells .. as well as 1151 excretory capacity of mice inoculated with 1251-iododeoxyuridine-Iabelled leukemic cells. It has been observed that the longest survival time of mice with LI210 leukemia is obtained when methotrexate is administered prior to 5-fluorouracil. Reversing the schedule, or simultaneous administration of the drugs results in shorter survival time. despite the administration of 5-fluorouracil at low doses, ineffective on LI210 leukemia in monotherapy. Cytotoxic effects on LI210 leukemic cells labelled with 1151UDR were present only when methotrexate was administered prior to 5-fluorouracil.


Three-dimensional bicovariant differential calculus on the quantum group SU q (2) is constructed using the approach based on global covariance under the action of the stabilizing subgroup U (1). Explicit representations of possible q-deformed Lie algebras are obtained in terms of differential operators. The consistent gauge covariant differential calculus on SU q (2) is uniquely defined. A non-standard Leibnitz rule is proposed for the exterior differential. Minimal gauge theory with SU q (2) quantum group symmetry is considered.

The duration from sowing to flowering is an important determinant of fibre yield potential in hemp, since maximum stem yield occurs shortly after flowering. As a short-day plant, daylength has a key influence on the timing of flowering in hemp. This paper reports on studies into the effect of photoperiod on the thermal time duration from sowing to flowering for 2 hemp cultivars, and develops parameters to enable simulation of post-emergent phenology in the hemp model described in the final paper of this series. The hemp model divides the post-emergent period into a vegetative phase that ends at floral initiation, aflower development phase (FDP) between flower initiation and appearance, and a short phase between first flower appearance and harvest maturity (male anthesis). The vegetative phase is further divided into a temperature-dependent basic vegetative phase (BVP) and a daylength-dependent photoperiod induced phase (PIP). For a short-day plant, the duration of PIP is assumed to be zero degree days at daylengths below a base or maximum optimum photoperiod (MOP). Daylengths in excess of the MOP lead to an increase in thermal time within PIP, the duration of which is determined by a genotype's photoperiod sensitivity (PS). Two hemp genotypes, Kompolti and Futura 77, were exposed to 6 different photoperiod regimes ranging from 8 to 16 h in a growth chamber. Thermal time durations from emergence to flower initiation and first flower formation (harvest) were calculated from thermograph plots. The flowering responses for the 2 cultivars were typical for a short-day plant, with flowering occurring rapidly in daylengths less than about 14 h and with increasing delay at longer photoperiods. With the exception of a longer thermal time duration from flower formation to harvest maturity in the case of Kompolti, the 2 cultivars had similar values for the key phenology parameters. Respectively, for Futura and Kompolti: BVP was 383˚Cd and 390˚Cd, MOP was 14 h and 13.8 h, PS was 266˚Cd/h and 252˚Cd/h, and FDP was 76.8˚Cd and 80.2˚Cd.


Hydrogen-stress cracking (HSC) has occurred in natural gas transmission pipelines only in localized hard regions in the pipe wall (hard spots) or in hard weld zones. A specific factor that results in the initiation of HSCs in some hard spots is the possible variation in localized electrolytic cell conditions that could exist because of variations in microstructure, hardness, and residual stress in those regions. This paper presents the results of a study of these variations. The first part of the study evaluates whether local variations in pipe-to-soil potential existed in hard spot regions subjected to an imposed potential. The second part involves monitoring the current flow and hydrogen entry into high-strength, line-pipe steels as a function of the imposed half-cell potential.It was concluded that the variation in potential was greater for a section of pipe removed from a hard spot than it was for a section that did not contain a hard spot. No correlation was found between the hardness variations and the half-cell potential variations. Consequently, factors such as surface condition of the pipe or variations in the residual stresses may influence the value of the half-cell potential and the amount of variation in the half-cell potential in hard-spot regions. The variations in half-cell potential that can occur in hard spots and the variations in residual stress that have been measured in hard spots do aid in explaining why the cracks that occur in hard spots frequently initiate at locations other than the hardest region.


Ovality is a main defect in all pipe bending techniques. An objective of the work is to control ovality in pipe bending. A new concept is suggested for reducing the flattening or ovality. Based on the concept, a mechanism is developed for bending pipes. This mechanism has provisions for precompression of the pipe along the directrix of maximum deformation during bending. Experimentation is carried out on this mechanism and dimensions are measured at 13 discrete places along the length of the pipe. Percentage ovality is computed using experimental results. It is justified by using equations of radius and displacement functions. Minimization of potential energy by sequential search method is done. The methodical approach is presented in this paper. Results show that precompression reduces ovality of the pipe after bending.


Language is a communication tool that is a symbolic system of sound produced by a human speech tool. Language as a means of communication can not only talk, but can be manifested by hand signals or other bodies that have their own rules. Language has a central role in the intellectual, social, and emotional development of students. This means every human being is subject to limitations in the language. The development of children's speaking skills in elementary schools will become the language for their effective and efficient communication. Learning to read in primary school is very important. This is caused by learning that can not only be utilized in improving the language skills of children, more than that, that is to improve students' ability in learning other subjects. The essence of writing skills is to increase the vocabulary insight for students, so that students are encouraged to think dynamic, critical, rational and able to live up to the conditions and goals of good and true teaching. However, on various matters relating to the process of reading and writing beginning in elementary school. This should not be allowed to happen continuously will cause an imbalance in the development of students' thinking ability. In addition to teachers, parents also play an important role in helping to solve problems by learning to read and write the beginning. Here the authors formulate some efforts to overcome this, namely: choosing reading materials, making the media as a song, choose innovative learning media, and motivate students by providing feedback.


In this paper a learning activity is proposed that requires students to identify aspects of corporate annual reports related to the learning objectives being covered throughout an Intermediate Accounting II course through frequent quizzes, bringing life to financial statements and note disclosures, from one learning objective to the next. The quizzes become a framework to build learning momentum by repeatedly reviewing the basic attributes of financial statements, refreshing prior learning materials, and adding new content from current course materials, all while reviewing current events inherent with global, political, and economic challenges. Students report their learning is positively

This article describes the findings of a research work aimed at identifying the need for an efficient vendor in the metallurgical industry in Cali and Yumbo who is able to provide thermal treatment services, which are usually outsourced to vendors in Medellin and Bogota because of the deficient quality of local vendors. This generates an increase of costs and times associated with travel which, in turns, hinders productivity and competitiveness in the metallurgical sector. This study involved conducting in-depth interviews with purchasing managers and administering surveys to metallurgical companies that hire thermal treatment services. Most of the interviewees and respondents voiced their dissatisfaction with the service they are being provided at present and expressed the need to have a better service available.


We have attempted to simulate dispersion phenomena of aerosol bolus in a straight tube under the developing cyclic flow condition using finite element method. The computational scheme was first validated by solving pure diffusion equations and subsequently by comparing the computational results with analytical solutions. In simulating cyclic flow conditions, both symmetric and asymmetric velocity profiles were used between the forward and reverse flow. The diffusion coefficient of particles (d p


The invention relates to a method for the underground in-situ extraction of a hydrocarbon compound in an oil shale, which comprises the following steps: arranging at least one working well and one production well in an enclosed working region where the hydrocarbon compound in the oil shale is extracted, communicating the bottoms among the working wells by directional drilling after a drilling well enters an oil shale ore layer, injecting water and inert gas water vapor into the working well to form a near-critical water microenvironment, cracking the oil shale into organic compounds with different chain lengths to form an oil-water mixture, lifting the oil-water mixture to the ground through the production well, and obtaining the hydrocarbon compound through an oil-water separating system. The heat utilization ratio is improved through a multi-well integrated heat circulating system, the extraction ratio of hydrocarbon substances is greatly improved through repeated oil-water separating and circulating processes, and the technical process is shortened. A water micro-pool is formed after an oil shale layer is overflowed by water, the cracking of the oil shale can be realized within3 to 5 hours after a near-critical state is reached, and more energy sources and time are saved than an underground dry distillation method.


In this brief, the well-known switched-current (SI) filtering technique is revisited using the concept of the square-root domain (SRD) filtering. It is proved that SI filters are a subclass of the SRD filters, where sampled-data signal processing is performed. This is achieved by considering typical lossless and lossy SRD sampled-data integrator configurations, using a set of complementary SRD operators which are based on the quadratic I-V relationship of MOS transistor operated in the saturation. Circuit examples are given, where linear-domain integrator and third-order filter configurations were derived using appropriate SRD sampled-data building blocks


Insuring disaster risks can be challenging, due to spatial correlations and fat-tailed loss distributions. This chapter examines catastrophe insurance with a particular focus on events that alter risk assessments in the insurance industry. It addresses two questions: (1) What types of events lead the (re)insurance industry to update risk assessments? (2) How do companies, consumers, and the government respond to updated risk assessments? Updating is more likely to occur for risks with unknown or changing loss distributions. When an extreme event leads to altered assessments of the risk, insurance firms will reevaluate their pricing, exposure, underwriting policies, and capital management practices. Severe events that lead to this type of risk updating, however, also often lead to updating on the part of consumers and governments. This chapter traces how all three sectors may respond when they assess a risk as higher than they did previously. This may lead to temporary adjustments, or it could cause new equilibrium conditions in the market or permanent government interventions.

INTRODUCTION The rapid rate of urbanization undergoing in developing countries and the increasing pressures on what are often limited resources ask for sustainable interventions while these built environments are being created. This paper summarises the first results of a study that is investigating whether or not the laterite dimension stone can be a possible material to be use (when available) for housing, in rural as well as in urban areas. Laterite dimension stones have been used for building construction in tropical and subtropical regions of the world where they are readily available and economical compared to other natural stones. Although the definition of "laterite" is still quite controversial, it can be assumed that laterites are the products of intensive and long lasting tropical rock weathering which is intensified by high rainfall and elevated temperatures, and hence it is not possible to commonly class them (as igneous, sedimentary or metamorphic rock). Laterite can be treated as a "weak rock" for building purposes and, when moist, it can be easily cut into regular-sized blocks. However, after exposure to atmosphere, laterite blocs show a hardening behaviour which is thought to be due to the content and dehydration of iron oxides and arrangement of components.

By the optimum design of four factors quadratic regression, analysis was carried out on the dynamic regularity of nitrogen and chlorophyll content of Phyllostachys heterocycla var .pubescens foliage at different growing seasons. Regression analysis of nitrogen and chlorophyll content of these foliage and new bamboo leaves resulted a significant parabola regression correlation between nitrogen content of foliage collected in December and yield of new bamboo culm, and the same between chlorophyll content of foliage collected in April and yield of new bamboo culm. The optimum nutrient content and critical value of bamboo forest with 2 180culm/ha, the highest theory yield, calculated by regression equation were 31.15mg/g and 32.55mg/g. Correlation analysis on nitrogen and chlorophyll content of foliage showed that there was a linear correlation between them one month after applying fertilizer (in September), but a significant or remarkable significant parabola regression correlation in winter (December). This means there was a significant correlation between the nutrient content of leaves and physiological index in Ph. heterocycla var.pubescens.

Driven by increasingly severe water shortages, irrigation management advisory services will need to achieve dramatic advances in analytical capabilities in the span of a decade or two. Limited water supplies are driving the adoption of deficit irrigation strategies, requiring more precise control of soil water conditions to manage - rather than avoid - crop water stress. Increasing dependence on waste water reuse is stimulating interest in bioremediation in the rhizosphere for distributed, low cost tertiary treatment of irrigation return flows even before they leave the root zone. These paradigm changes will depend upon more precise management of soil water movement, dwell times and root system contact.

This paper studies tandem flocking of a team of unmanned aerial vehicles (UAVs) equipped with limited range sensors exploring an obstacle-rich GPS-denied environment such as a forest or urban canyon. There is no communication between UAVs and the follower can only estimate its leader's relative position by its on-board camera. A vision-based leader-follower flocking strategy is proposed to achieve this kind of flocking in unknown cluttered environments. The leader UAV explores its way to reach a given goal position and the follower UAV follows its corresponding leader UAV via on-board camera and avoid obstacles at the same time. The simulation of a team of six UAVs demonstrates the effectiveness of our proposed flocking strategy in a forest environment.

Continuous, small-diameter polymer fibers may be fabricated by a method that involves injecting a solvated polymer into a highly viscous moving medium through a microaperture. The extruded fiber moves in a predictable spiral path and is collected around a spinning mandrel that also serves to pull the extruded fiber away from the aperture. In this study, fibers as small as 400 nm diameter were observed, but there was no indication that the experiments reported here have achieved the smallest structures possible by this technique. Video microscopy experiments revealed significant fiber diameter reduction in close proximity to the point of precursor injection via hydrodynamic focusing. This occurred due to flow mismatch between the precursor and surrounding media. This effect may be the dominant draw-down mechanism in a process that can produce truly continuous nanofiber. This method is capable of generating fibers from precursors with viscosities that would render them unspinnable by any other known method.
