Introduction: Epidemiologic studies show that suicide and depression are among the most important mental health problems among societies. Therefore this research was carried out to compare suicidal decisions and depression among the suicide committed and healthy people in Ilam province. Methods & Materials: The comparative-casual study was carried out with regard to its utility for applied outcomes. The sample of research included 50 suicide committed individuals and 50 healthy people (non-depressed and non-suicide committed), referred to Imam Khomeini Hospital, Mostafa Khomeini Hospital, and Taleghani Hospital in Ilam in which the individual of experimental group were selected by the method of accessible sampling and the individual of witness group were selected by the method of cluster sampling. These groups were measured by application of BECK Depression Scale and BECK Suicide Decision. The statistical evaluations were carried out using SPSS statistical soft-ware. Correlation between the data was ass-essed by Pearson's coefficient of correlation (r) and T-Test Student. Findings: The results showed that there was a significant difference for the level of depression between the suicide committed and healthy groups (p<0.001). Also, there was a significant relationship between suicidal thoughts and the level of depression. (p<0.001, r= 0.79). Discussion & conclusion: The findings validated differences of the level of depression and suicide thoughts among individual of both group. Therefore in order to protect and promote mental health, it is obligatory to consider the effectiveness role of these variables in screening tests and mental health monitoring. It is strongly suggested to carry out a comprehensive study in the domain of depression and suicidal thoughts especially among the youth society and to pay more attention to forecasting role of depression and suicidal thoughts as risk factors to commit suicide in order to prevent this social disorder.


The problem of current importance which is how to improve the effectiveness of patient's status severity estimation in a case of traumatic pancreas injury is under discussion in the paper. The method which operates with bounded set of patient's physiology state parameters, which are available for urgent definition, is suggested. This method is developed by using multidimensional discriminant functions analysis and it allows distinguishing different grades of patient's status severity more precisely in comparison with methods, which are in use in a case of blunt pancreas injuries nowadays.


In order to solve the problem that the paper will be wrapped and distorted after being laminated by the paper laminating machine, an auto flip delivery mechanism of the paper laminating machine is designed. A set of flip mechanism is installed in the delivery part of the paper laminating machine for placing the small paper stacks right side up or side down, which effectively prevents the laminated paper from being wrapped and distorted. Comparing with manual delivery, it saves labor, reduces the number of employers and also reduces the cost of the enterprises. The effectiveness of the mechanism has been verified in its actual application.

Based on the existing model of pipe-roof considering the arching effect, combined with the mechanical model of pipe-roof when the tunnel is excavated to the end, a unified mechanical model of the elastic foundation beam for pipe-roof is established. Deflection and internal force calculation formulas of the model were derived. Combined with actual engineering cases, the model was compared and analyzed, and the parameters affecting the pipe-roof were analyzed by taking the unified model as an example. The results show that the established unified elastic foundation beam model can better represent the actual stress state of a pipe-roof and the model has strong applicability. The stress state of the pipe-roof at the end of excavation can be calculated by changing the boundary conditions of the model. When the diameter of the steel pipe is 108–114 mm, the supporting effect of the pipe-roof is similar. When E c (elastic modulus of converging) > 40.0E g (elastic modulus of ground rock), the excavation footage and the diameter of the steel pipe have little effect on the deflection and bending moment of the pipe-roof. Therefore, increasing the elastic modulus of the reinforced area is the most effective method to reduce the deflection and internal force of the pipe-roof. The longer the residual length of the pipe-roof in surrounding rock, the safer the tunnel will be during excavation. The economically reasonable value of the residual length of the pipe-roof in surrounding rock is 2–3 m.


We have shown that: (1) Li+ ions are inserted reversibly, without diffusion control, up to the level of at least 4 moles Li+ ions per mole for V2O5, in the aerogel (ARG) form (500 m2/g specific surface area) and aerogel-like (ARG-L) form (200 m2/g specific surface area)(6,7,1,2); (2) polyvalent cations (Al+3, Mg+2, Zn+2) may be intercalated reversibly into V2O5 (ARG) with high capacity (approaching 4 equivalents/mole V2O5 (ARG)) for each (5); (3) dopant cations such as Ag+ and Cu+2 increase the conductivity of V2O5 (XRG) up to three orders of magnitude(3), they are electrochemically active – showing reduction to the metallic-state in parallel to intercalation of Li+ ions – but are not released to the electrolyte upon oxidation and Li+ ion release (Cu+2 ions are reduced to Cu metal and reoxidized to Cu+2 in Li+ ion insertion/release cycles, but the copper ions are not released to the electrolyte over more than 400 cycles of the XRG form); (4) we have shown that Cu+2 ion (dopant) and Zn+2 ions (chemical insertion and dopant) occupy the same intercalation site inV2O5 xerogel and aerogel(4); (5) the reversible intercalation of Zn+2, Mg+2, and Al+3 in the ARG(11) indicates that these cations are "mobile", butmore » that Cu+2 ions and Ag+ ions are "immobile" in the xerogel, i.e., the latter ions are not exchanged with the electrolyte in Li+ ion intercalation cycling(3).« less


Vertical tubes are commonly used in industrial fluidized beds as heat exchanger tubes. In this study, the influence of vertical tube banks on the axial bubble growth in a 145-mm inner diameter (ID) fluidized bed with Geldart B particles is experimentally investigated by means of pressure fluctuation measurement (PFM) and optical probing (OP). The employed tube bank configurations differ in their tube-to-tube spacing, tube diameter, and tube arrangement (square versus triangular). PFM and OP show that immersed vertical tube banks, irrespective of their configuration, significantly reduce the axial bubble growth. The bubble size reduction is even more significant for higher gas velocities (u0/umf > 4.6, where u0 is the superficial gas velocity and umf is the minimum fluidization velocity) as well as if the tube-to-tube spacing is narrow and the tube diameter is small. The tube arrangement (square versus triangular), in turn, does not show any significant differences. Depending on the gas velocity, the ratio...

Smallholder farmers like those in Limpopo and the Free State (FS) Province of South Africa sometimes incur high production costs due to their crop choices. This cost is exacerbated by the challenges posed by climate change and the socio-economic position of the smallholder farmers. The opportunity cost of producing cost-intensive crops is the forgone benefits these smallholder farmers would have gained if they grew cheaper options. Therefore, a tool to assist farmers and stakeholders when choosing, advising on, or assisting with production and management decisions at farm levels to ensure profitability and sustainability is needed. This paper aimed at providing a framework to assist farmers in identifying profitable crops for production under the present day and possible future scenarios in Limpopo and the FS. This framework uses a multi-stage process with forward and backward linkages to refine analysis and results. Through reviews, interviews, focus groups and transect walks, the state of the biophysical, socio-economic, and political environment and their impact on smallholder farming were collected from 600 farmers and 40 key informants. Inferential statistics and cost-benefit analysis were used for data analysis. The results indicate that maize, though widely cultivated in both Provinces, has the highest average total production cost of R 29,694.39 /ha while the lowest was sunflower with R 6,453.78 /ha. Irrigated maize had the highest break-even price per hectare of R 38 351.85, while sunflower had the lowest R 4 685.85. In both provinces, groundnut ranked first on Net Present Value (NPVs) at discount rates of 8% and 10%, while low yield maize ranked last, scoring values of –R 4 163 894 and –R 3 953 393. Groundnut had the highest Benefit Cost Ratio (BCR) at 2.22 and 6.70 in Limpopo and FS. The BCR for low-yield maize was the lowest of all the crops. The base scenario results in economic and financial terms indicate it is better to farm sunflower, soybean, grain sorghum, and groundnuts than maize because of lower production cost and maize substitutes. Furthermore, climate change projections suggest a drier future for these provinces, implying the yield targets for farmers producing maize would be difficult to achieve when faced with climate change. Such information is vital for stakeholders.


Total genomic DNA was extracted from Polygonum capitatum by a modified cetyltrimethyl ammonium bromide(CTAB)protocol. The purified products of PCR amplifications were directly sequenced, associated with rDNA ITS sequences in triplicate, using consensus primer pairs. Nucleotide sequence analysis, phylogenetic tree and homology were performed with Clustal X software and DNAMAN programme based on DNA ITS sequences. The results indicated that the sequences of rDNA ITS were 661 ~666 bp in P.capitatum, and 13 variable sites, mainly concentrated in the ITS1 and ITS2 area. We argued that rDNA ITS sequences could be applied to explore molecular identification to determine the sampled eco-geographic origins in P. capitatum.


Bilirubin is more than just the final product of heme catabolism. Today it is considered to be a fundamental substance which acts as an antioxidant and anti-inflammatory agent in the serum. It can neutralize free radicals and prevent peroxidation of lipids. In addition there is evidence that it protects the cardiovascular system, neuronal systems, the hepatobiliary system, the pulmonary system and the immune system. Recently the use of pharmacological agents which augment expression of Heme oxigenase 1 (HO-1) has been investigated. Consequently its metabolites such as carbon monoxide (CO), biliverdin (BV) and bilirubin (BR) could become parts of a therapeutic strategy for treatment of various inflammatory illnesses. Reactive oxygen species (ROS) and signaling events are involved in the pathogenesis of endothelial dysfunction and represent a major contribution to vascular regulation. But depending on the amount of ROS production it might have toxic or protective effects. Despite a large number of negative outcomes in large clinical trials (e.g., HOPE, HOPE-TOO), antioxidant molecules and agents are important players to influence the critical balance between production and elimination of reactive oxygen and nitrogen species. With the present review we would like to highlight the important antioxidant role of the HO system and especially discuss the contribution of the biliverdin, bilirubin, and biliverdin reductase (BVR) to these beneficial effects.


In Thailand, economic inequality has long been a fact of life. It is a "general inequality of condition" that can be seen to influence all aspects of social, economic, and political life. Yet inequality has not always been associated with political activism. Following the 2006 military coup, however, there has been a deliberate and politicized linking of inequality and politics. The article explores a complex of political events – elections, coup, constitution, and the political ascent of Thaksin Shinawatra – that has given rise to a relatively recent politicization of economic and political inequalities, now invoked in street politics – a rhetoric developed amongst pro-Thaksin red shirts that challenged the status quo and generates conflict over the nature of electoral democracy.


Under the premise of ensuring fairness of electricity prices, a novel bi-level optimal model considering the influence of uncertainty and real time electricity price is proposed to evaluate the maximum operation duration of the isolated island formed after fault. The proposed bi-level optimal model is solved by dichotomy and YALMIP. Based on the improved IEEE13 node system, the effects of real-time electricity price on the maximum operation duration of islands under different cases are compared and analyzed. The simulation results indicate that the proposed method can effectively evaluate the maximum operation duration of the island, and the operation capability of the island could be improved by reasonably optimizing the electricity price in island.


Learning can be defined as a change in behavior due to practice or experience. For learning individual mayneed to repeat the experience in order for the behavior to change .Sometimes learning may be so strong that may result in change of behavior. Learning can be said as a adaptive process in which the tendency for a particular behavior is changed by the experience. As the conditions and situations change people lean new things, may or may not be eliminating old ones. New and old things can be accumulated together so as to bring more fruitful results of learning. Learning basically consists of attention, in which a individual may notice or observe something in the environment, retention individual remembers what was noticed, reproduction, individual replicates what was noticed and motivation a consequence is generated for further learning. Process of learning also involves the trial and error, such is the case when individual is having no teacher or reference for instruction him. Learning in AI is generally based on empirical data and is associated with non-symbolic AI, scruffy AI and soft computing. Learning by AI is developed so as to develop more effective and efficient learning systems. Our paper discusses some of the important learning systems developed by the AI.


INTRODUCTION
Metabolic syndrome is a systemic disorder and manifests as a group of conditions including abdominal obesity, dyslipidemia, hypertension and coronary artery disease. The importance of epicardial adipose tissue has been proven through recognition of its contribution to inflammation by pro-inflammatory cytokine discharge. Several investigations have been performed on vitamin D receptors in different tissues. In this study, epicardial adipose tissue thickness (EATT) and the levels of vitamin D were measured and compared with a healthy control group.

MATERIAL AND METHODS
84 patients who had metabolic syndrome without diabetes and 64 healthy individuals were enrolled into the study. In all patients, the EATT was calculated by ecocardiography and the level of serum 25 (OH) vitamin D was measured.

RESULTS
It was observed that EATT in patients with metabolic syndrome increases significiantly compared to the healthy control group (P < 0.001). No significant difference between patients and control group was found for the levels of 25 (OH) vitamin D (P = 0.507). There was no correlation between 25 (OH) vitamin D and EATT (P = 0.622).

CONCLUSIONS
We observed that EATT increased in patients with metabolic syndrome. In contradiction to literature; the levels of 25 (OH) vitamin D was not found to be high in patients with metabolic syndrome. Any significant correlation was not found between EATT and 25 (OH) vitamin D levels. Further studies with a larger patient population are required to assess the relationship.


Abstract The paper deals with the modal analysis and frequency response analysis of a bucket wheel excavator (BWE) boom, obtained by simulation, based on a virtual model of an existing BWE boom. The boom, which generally is realized as a spatial truss, is the most vulnerable subsystem of the BWE, being submitted to severe operational loads characterized by very pronounced cyclical, dynamic and stochastic variability. This vulnerability is the consequence of its shape and constructive parameters and the nature, source and character of the external exciting loads to which it is exposed. The classical approach recommended by standards and norms cannot predict the occurrence of failures caused by vibration, which produces fatigue due to the load's cyclical variability and the deformation produced by resonant vibration of some constitutive elements. As exciting load we considered the operational forces acting on the bucket wheel. In this manner we can take into account the constructive features – with modal analysis, and the vibration regime – with frequency response analysis. The proposed method is useful both in the design phase of new load-bearing structures of truss type subjected to high-variability forces, and also in refurbishment or improvement phases of the existing structures of this kind.

An integral Interacting Boundary Layer theory is presented for the steady laminar flow in a asymmetrical bidimensional channel at high Reynolds number. The effect of asymmetry of the geometry is taken into account into the ideal fluid pressure expression. The effect is small but noticeable. Comparison with a Navier–Stokes solution shows the trend of asymmetry: increasing the pressure drop on the more curved wall, decreasing it on the other. Separation and reattachment of the boundary layer are obtained and compare well. © 2006 Elsevier Masson SAS. All rights reserved.

A large debris flow disaster was triggered by a heavy rainfall in Hongchun valley,Yingxiu town on August 14,2010.The debris flow carried out a lot of loose sediments and the total amount is about 80.5 × 104m3.This debris flow led to serious secondary disasters including Minjiang river was blocked,Yingxiu town was flooded,the 213 highway was interrupted,the roadbed and bridge pier of a ramp bridge was destroyed.According to survey,a large number of loose sediments was distributed in the groove before the disaster.,the valley was clogged seriously. So the outbreak of debris flow was inevitable in the condition of strong rainfall.To prevent the occurrence of debris flow again,a detailed investigation was carried out around Hongchun valley.The results showed that there were still many loose sediments of about 310.14 × 104m3.Among unstable reserves,the loose sediments were about 98.4 × 104m3.Large-scale debris flow disasters were extremely easy to outbreak in condition of strong rainfall.This paper introduces the debris characteristics,and analyzes its risk and development trend.Furthermore,it formulates the management roadmap of debris flows and puts forward the concept of the whole basin comprehensive treatment.In order to control debris flow disaster happening again,reinforcing management and loose sediment retaining measures are carried out in the middle and upper reaches of the valley.Solid groove bed and platoon guide measures are constructed in the downstream.After the completion of project,during two heavy rainfalls in July and August,2011, there was not any solid loose sediments into Minjiang river and the treatment project was fine,which can reflect that the whole basin comprehensive treatment design concept has good effect for preventing giant debris flow.


Recent thermochronologic data from the Annapurna region of central Nepal show very young ages in the footwall of the Main Central Thrust (MCT), with late Miocene-Pliocene Th/Pb monazite ages especially common 5-15 kilometers south of the MCT (Catlos et al., 2001). These data can be explained with several different models, including: 1) Reactivation of the MCT and its splays in Miocene-Pliocene time with motion on some faults continuing to the present (e.g. Catlos et al., 2001); 2) Growth of a duplex beneath the MCT that passively lifted both the footwall and the hangingwall of the MCT in Miocene-Pliocene time (e.g. DeCelles et al., 2001); 3) A combination of MCT reactivation and duplex growth. When combined with structural mapping, our pilot dataset of in situ monazite Th/Pb ages from hangingwall and footwall rocks in the Madi Khola allows us to begin to validate aspects of some models and eliminate others. Our structural and thermochronologic interpretations are enhanced by Nd isotopic analyses that accurately constrain the location of the MCT (defined as the crustal boundary between Lesser Himalayan and Greater Himalayan rocks). We use Nd isotopes to map the MCT across the 60 kilometers between the Modi and Marsyandi Rivers based on previous studies that showed that Lesser Himalayan rocks contain more radiogenic Nd than Greater Himalayan rocks. In addition to identifying potential structural modifications of the MCT, our map will be useful for future studies in the Annapurna region because the critical task of locating the MCT is not always straightforward in the field.

To explore the technological feasibility of the intelligent chameleon camouflage material,polymer-dispersed liquid crystal(PDLC) devices were prepared by the light-induced phase-separation method.Effects of the polymer content on the morphology and the electric-optical properties of PDLC devices were studied.The influence of the device thickness on the electric-optical properties of PDLC devices was also investigated.Results indicate that the PDLC devices with the polymer content of 40% and the device thickness of 9.8 μm could work with a low voltage,high contrast and stability,and guide the fabrication of the flexible chameleon camouflage material.PDLC has a potential application in the display,sensor,optic-electronic switch,optical grating and other new analytical devices.


A standardized test of sensitivity (following DINx 58 940) to 10 chemotherapeutic agents was conducted on 49 Pasteurella and 10 C. pyogenes strains. These strains had been isolated from nasal or pulmonary secretions of calves with bronchopneumonia or from affected lung tissue of animals that had died. Resistance rates were determined on the basis of minimal inhibitory concentration or by the disk diffusion method. These were: for erythromycin 0%, tri- methroprim/sulfadoxine 2.3%, penicillin G 20.5%, ampicillin 24.5%, kanamycin 24.5%, neomycin 32.7%, chloramphenicol 43.2%, sulfamethazine 54.5%, oxytetracycline 63.6%, and streptomycin 75.5%. C. pyogenes proved to be highly sensitive to penicillin G. Routine checking of resistance patterns is necessary for achieving effective trf* tment of bronchopneumonia.


In this paper, we propose the integration of a cartography gathering scheme to enhance the capacity of the Optimized Link State Routing Protocol (OLSR) to properly track node movements in dynamic networks. We propose an improved version of OLSR called the Cartography Enhanced Optimized Link State Routing Protocol (CE-OLSR), a novel routing protocol designed for mobile multi-hop ad hoc networks. Our contribution is three fold. First, we propose an efficient network cartography collection scheme solely based on OLSR signaling traffic. We show that this cartography is much richer than the mere topology gathered by the seminal OLSR. Second, we designed an enhanced version of OLSR based on the collected cartography. We show that CE-OLSR insures a much better responsiveness and copes appropriately with the mobility of nodes. Third, we conduct an extensive set of simulations to compare the performance of our proposal against that of OLSR. Simulations results show that the proposed CE-OLSR outperforms greatly OLSR in terms of a much better route validity, a much higher throughput and a much lower average delay. For instance, at a speed of 20 m/s, CE-OLSR achieves a route validity beyond 93% while that provided by OLSR barely attains 30%. At high speeds, CE-OLSR delivers more than 3 times the throughput of OLSR with an average end to end delay 21 times smaller. As such, CE-OLSR stands out not only as an appropriate routing protocol for mobile multi-hop ad hoc networks, but also a viable protocol for the transport of time critical data.

The utility model has the advantages of light weight, small size, sensitive operation and low noise in use; flow is uniform, and the minimum flow reaches to 0.2 m / h. The utility model has high mechanical efficiency and long service life.


The effects of impurity scattering on a general Abelian fractional quantum Hall (FQH) edge state are analyzed within the chiral-Luttinger-liquid model of low-energy edge dynamics. We find that some disordered edges can have several different phases characterized by different symmetries. The stable impurity edge phases are in general more symmetric than the original clean system and demonstrate the phenomenon of dynamical symmetry restoration at low energies and long length scales. The phase transitions between different disordered phases are characterized by broken symmetries and obey Landau's symmetry breaking principle for continuous phase transitions. Phase diagrams for various edges are found using a new system of coordinates for the interactions between modes in a quantum Hall edge. The temperature dependence of tunneling through a point contact is calculated and is found to be able to distinguish different impurity edge phases of the same FQH state.

Immobilization of compartmentalized microscale objects in three-dimensional hydrogels provides a step towards the modular assembly of soft functional materials with tunable architectures and distributed functionalities. Here we use a combination of micro-compartmentalization, immobilization and modularization to fabricate and assemble hydrogel-based micro-reactor assemblies comprising millions of functionalized polysaccharide-polynucleotide coacervate droplets. The heterogeneous hydrogels can be structurally fused by interfacial crosslinking and coupled as input and output modules to implement a UV-induced photocatalytic/ peroxidation nanoparticle/ DNAzyme reaction cascade that generates a spatiotemporal fluorescence read-out depending on the droplet number density, intensity of photo-energization and chemical flux. Our approach offers a route to heterogeneous hydrogels with endogenous reactivity and reconfigurable architecture, and provides a step towards the development of soft modular materials with programmable functionality.

The preparation of some new 3-quinolinylchalcone derivatives was described. Their reaction with hydrazines, hydroxylamine hydrochloride, malononitrile and ethyl cyanoacetate gave the corresponding pyrazoline, isoxazoline, cyanopyridine and cyanopyridone derivatives, respectively. The biological activity of some of the products was evaluated.


Taxable or Not Taxable? In the rush to finish their tax return, had he made a mistake? Were the "free" ticket vouchers they had received for volunteering to give up their airline seats something on which they should be paying income taxes? Harrison had forgotten all about the vouchers until Joan, his wife, interrupted him by asking whether they flew on Friday or Saturday of their fast-approaching vacation. The vouchers seemed like "free money" and a good deal when they had volunteered to give up their seats, but now they wondered, did they need to be included on their tax return? After all, no notification (a Form1099) had been received that would have indicated that the vouchers were taxable income. And if the vouchers had not been reported to the IRS, did he need to worry about including them on their tax return? After all, the tickets were free weren't they? But in the U.S. tax system that requires "voluntary" reporting, was there a moral or legal obligation to report the tickets as income, even if the IRS had no written record of them? In the little research he had done earlier, he had not found anything that indicated that the ticket vouchers were taxable. Maybe his earlier suspicions were just wrong; maybe the vouchers weren't taxable. After all, there couldn't be much extra cost to the airline of flying a couple more passengers in what otherwise might be empty seats. If the airline's extra costs were negligible, then maybe the flip side was that there was only negligible income on the part of Joan and Harrison that was so insignificant it did not even need to be reported on their income tax return. Alternatively, maybe the tickets were just compensation for damages for having to take later flights. But then, he wondered, was compensation for damages taxable? A phone call to Randy provided some comfort. Knowing that Randy, who still prepared taxes for a few friends left over from when he had been in the tax preparation business, was no doubt swamped this close to the tax filing deadline, it was with hesitation that Harrison called him. They were friends, but Harrison was not one of Randy's clients. The ensuing discussion was cordial, but understandably brief. Randy had never given the matter any thought but had never heard of anyone filing either frequent flyer miles or free airline tickets that they had received as taxable income, and he didn't see why Harrison should. Free Tickets Bonanza The story behind the free tickets began when Harrison and Joan had decided to celebrate their wedding anniversary early for a change, over the Thanksgiving holiday break, as Harrison's schedule did not allow him to be out of town in early December. Over coffee, a friend who worked with Joan, told of an acquaintance in Florida who had a house in the Bahamas that she sometimes rented to vacationers. Really, it was her second home; she regularly went back and forth between her home in Florida and the beachfront home in the Bahamas. After talking it over with Joan the night before, Harrison had phoned to inquire about the house and its availability. The owner said the house was a nice place; she did not want it exposed to heavy traffic that would put a lot of wear on it. It was neither advertised nor part of a rental pool. It was a two bedroom beach front home nestled in the palm trees on the shore of a cay, just off the coast of Eleuthera. It had great views and an almost deserted shore line that was perfect for beachcombing and long peaceful walks, when one wasn't out snorkeling. Although she did not frequently rent it, her divorce had left her with limited cash flow, and by referral, she now sometimes rented it to supplement her income when she wouldn't be using it herself. On the phone, it sounded like a dream place to celebrate their anniversary and a safe destination for their first trip out of the country. Perhaps after many years of "pinching pennies" to just get by, he and Joan "deserved to splurge. …


ABSTRACT The use of eyelid switch flap in the correction of lower eyelid coloboma in a post-traumatic contracted socket is described. The lower eyelid, inferior fornix and lateral canthus were successfully created in a single stage with a switch flap from the upper eyelid. A satisfactory cosmetic outcome and a stable fornix for placement of a custom ocular prosthesis was achieved.


The explosion of interconnected devices and the Internet of Things has triggered new important challenges in the area of internet security, due to the various device vulnerabilities and increased potential for cyber-attacks. This paper touches on the areas of Cybersecurity, intrusion detection, prevention systems and artificial intelligence. Our aim is to create a system capable of understanding, detecting and preventing malicious connections using applied concepts of machine learning. We emphasize the importance of selecting and extracting features that can lead to an accurate decision of classification for malware and intrusion attacks. We propose a solution that combines features that extract correlations from the packet history for the same and different services and hosts, based on the rate of REJ, SYN and ACK flags and connection states, with HTTP features extracted from URI and RESTful methods. Our proposed solution is able to detect network intrusions and botnet communications with a precision of 98.4% on the binary classification problem.


Pure acetone-d6 has been prepared by reaction of heavy water with propyne-d4 in the liquid phase and a mercury catalyst. Propyne-d4 was obtained by hydrolysis of magnesium carbide Mg2C3 with heavy water. A practical procedure for 20 g amounts of acetone-d6 is given in detail. Its over-all consumption of heavy water exceeds the theoretical amount by only 5–10%.

A method and apparatus for error concealment in a video sequence. There is a scene transition into a video sequence, if there is an error in the image belonging to a scene transition, error concealment procedure is utilized based on the type of scene transition to conceal errors. Information about the type of scene transition is supplied to the video decoder in the extended information message. If the scene transition is a gradual scene transition, spatial to conceal an image - temporal error concealment algorithm is utilized. Scene transition is a scene cut, in cases where only a portion of the image is lost or damaged, lost or spatial error concealment to conceal damaged portion of the image is utilized. Entire image belonging to the scene cut has been lost or damaged, the concealed image when the image is to start a new scene is not concealed.


The concept of value is so wide that could be considered as synonymous with human life and existence. The human being is engaged in the evaluations of being by doing every act. Life is a value that even its ascetic denial is a kind of valuation. When the human being enters the world, in fact he enters a pre-valued world and many values weighed upon him. To what extent is man capable of emancipating from pre-existing values and to what extent can he succeed in creating value? The complex world today is very similar to the mythical world in which the blind and deaf valuing forces have overwhelmed and conquered human choices. It is here that human choices show a confusing and algebraic procedure, and freedom is as s chain that human being wrap around himself.


We report, in this paper, the synthesis of DySi2 layers on Si surfaces by high-current Dy-ion implantation in Si wafers using a metal vapor vacuum arc ion source. It was found that the continuous DySi2 layers could grow at a relatively low formation temperature of 190°C and that the surface morphology varied with the variation of the implantation parameters. The formation mechanism of the equilibrium DySi2 phase as well as the continuous DySi2 layer on Si surface is proposed in terms of ion beam heating and the effect of ion dose on the Dy-ion implantation process.


In France, the last five years have been marked by the reforms of the lessons of the college and high school. It is in this context that the design has made its entry in the teaching of technology at the college and in the series STI2D (Science and technology of the industry and sustainable development). In parallel with this entry of the design in technology education, the series STD2A (Science and Technology of Design and Applied Arts) strengthens the place of lessons technological and scientific in the learning. This evolution of knowledge taught, by the link between design and technology, naturally connected in the industrial professional field, but treaty separately to the school, accentuated the fact to rethink teacher training. This paper aims to address the issue of the interactions between design and technology in education in college and in high school, and to think about teacher training. The analysis presented here is based on observations made within the curricula of applied arts and technology in France as well as within the activities of teaching and learning of students, for students and teachers. How to teach Design and Technology to teachers who will be responsible to account for the relationship of these two professional fields to students in college and high school? In what the concepts of vocational teaching and activity of design can help to understand the process that led, today, to teach the knowledge on the design to teachers whose profiles are also different? To answer these questions, we focus on the study of the establishment of a Master Craft of the teaching of the training and education option "Technology & Engineering of industrial design" in France. It will be as well to think about the objectives associated with the training of teachers for college and vocational "lycee" and their ability to articulate technological education and teaching of design thus aiming to circumscribe the effectiveness of their practices.

Forty-three Colletotrichum isolates fromLupinus species worldwide are delineated into 3 groups:vegetative compatibility group (VCG)-1 (4 isolates), VCG-2 (37 isolates), andCOL-3 (2 isolates). The 3 groups are readily distinguishable by randomamplified polymorphic DNA (RAPD) profiles. All Australian lupin isolates areVCG-2. VCG-1 and VCG-2 isolates produce predominantly cylindrical conidia, hadregular colony margins, and were grey to brown, lacking pinkish pigmentationon potato dextrose agar (PDA) consistent with the taxonomic criteria forColletotrichum gloeosporioides. COL-3 isolates producepredominantly fusiform conidia, and had an irregular colony margin and apinkish pigmentation on PDA consistent with C. acutatum.COL-3 isolates are possibly strawberry pathogens which can cross-infectlupins. An examination of reference cultures ofC. gloeosporioides and C. acutatumfound that published 'species specific primer' polymerase chainreaction (PCR) tests based on ITS sequence homology produced results contraryto the traditional taxonomy based on morphology. RAPD analysis appears todetect greater genetic variation in Colletotrichumisolates than previously published ITS1 sequence homology data, which does notsupport moving lupin anthracnose pathogens VCG-1 and VCG-2 fromC. gloeosporioides intoC. acutatum. Additional key words: Colletotrichum gloeosporioides,Colletotrichum acutatum, Lupinus,vegetative compatibility, RAPD analysis.


The invention provides a shell and an electronic device with the shell. A nameplate is attached to one surface of the shell, and a plurality of pits are formed in the region, where the nameplate is attached, of the shell. According to practices, due to the fact that the pits are formed in the region , where the nameplate are attached, on the outer surface of the shell, air bubbles with different sizes can be effectively prevented from appearing on the nameplate during high-temperature high-humidity storage tests, low-temperature storage tests and temperature and humidity circulating tests.

Abstract: A prevalent neurodegenerative condition known as Parkinson's disease (PD) is characterized by a movement disorder with bradykinesia, rest tremor, rigidity, and postural instability. The majority of contemporary PD treatments are predicated on restoring dopaminergic tone in the striatum; however, there are few effective choices available. These, however, do not change the course of the disease and do not address the dopamine-independent symptoms of PD, such as freezing gait, cognitive impairment, and other non-motor aspects of the condition, which frequently have the biggest effects on quality of life. Novel therapy approaches are developing as our understanding of Parkinson's disease pathophysiology increases. These include therapies that target PD symptoms while avoiding the unfavorable side effects associated with currently available therapies, as well as therapies that halt pathology, minimize neuronal loss, and moderate disease progression. This article discusses some promising approaches that are currently being researched in the laboratories or are in the clinical trial phase such as cell based therapies, gene therapy, neuronal therapy, infusion therapy, neuron regeneration and novel drug approaches, which can pose as the future for the treatment of Parkinson's disease


A planar rectangular microstrip patch antenna fed at the center with microstrip fed technique is being presented in this paper. The proposed patch antenna designed using Ansys HFSS, is having a pair of boomerang shaped slots and two notches both being symmetrical to the y-axis. Two u-slots in the ground plane augmented the total bandwidth. The antenna operating frequency is in the ultra-wide band range and achieved a bandwidth of 7.11 GHz from 2.43 GHz to 9.54 GHz. The obtained radiation pattern from the simulation showed broadside pattern in the direction of the radiation with very small back lobes when operated in the operating band. Thus the proposed microstrip antenna can be utilized for various applications incorporating Bluetooth (2.402 GHz–2.480 GHz), WLAN {2.4 GHz–2.4835 GHz (IEEE802.11b, g); 5.15 GHz–5.35 GHz (IEEE802.11a) and; 5.725 GHz–5.85 GHz(IEEE802.11a)}, UWB (3.1 GHz–10.6 GHz) and WiMax {2 GHz–u66 GHz (IEEE802.16); 2 GHz–11 GHz (IEEE802.16a)} operation.


This book is an exposition of Thurston's theory of surfaces: measured foliations, the compactification of Teichmuller space and the classification of diffeomorphisms. The mathematical content is roughly the following. For a surface M (let us say closed, orientable, of genus g > 1), one denotes by S the set of isotopy classes of simple closed curves in M . For α, β ∈ S, one denotes by i(α, β) the minimum number of geometric intersection points of α′ with β′, where α′ (resp. β′) is a simple curve in the class α (resp. β). This induces a map i∗ : S → R+ which turns out to be injective. In fact, if one projectivizes R+ \ 0, then i∗ induces an injection i∗ : S → P (R+) which endows S with a nontrivial topology. Here R+ is endowed with the weak topology ( = product topology). Two curves α, β ∈ S are "close" in P (R+) if, up to a multiple, they are made up of more or less the same strands going more or less the same direction. This is very different from saying that the curves are homotopic. The limits of curves are naturally interpreted as projective classes of "measured foliations", that is, foliations that have an "invariant" transverse distance, and that have certain kinds of singularities (wellknown in the theory of quadratic differentials, or in smectic liquid crystals). The space of measured foliations considered in R+ (or in P (R+)) is denoted by MF (resp. PMF). One shows that MF ≃ R6g−6 and PMF ≃ S6g−7. In P (R+), the space PMF(M) and the Teichmuller space T (M) glue together into a (6g − 6)-dimensional ball: T (M) = T (M) ∪ PMF(M) = D6g−6. The group Diff(M) acts continuously on this compactification of T (this is hence a "natural" compactification). Hence any φ ∈ Diff(M) has a fixed point in T (M) (Brouwer) and the analysis of this fixed point shows that (up to isotopy) each φ is either a hyperbolic isometry of M , is "Anosov-like" (the word is "pseudo-Anosov"), or else is


Purpose – The purpose of this paper is to explore the changing face of airline quality by analyzing the reported service and safety data for the traditional and low cost carriers.Design/methodology/approach – Data were gathered from Department of Transportation records on service and safety quality from 1996‐2004. A safety rate was calculated for each carrier by adding accidents, incidents, near mid‐air collisions, and pilot deviations and dividing the total number by yearly departures. The service rate was calculated by adding all complaint categories and dividing by yearly departures. Averages and confidence intervals were calculated. Analysis of variance was performed on group means.Findings – The findings of this study indicate that the low cost carrier group examined here has closed the gap on its traditional rivals in the area of safety quality, posting safety rates that are not statistically different from the traditional carriers over the period of this study. On the other hand, it has not as a gr...


Clearly, biogeographers do not know their tapirs from their...tapirs! Our splendid cover photo of a mother tapir with its young, which so charmingly adorned Journal of Biogeography Volume 29(1), January 2002, turned out to be not a picture of the said mountain tapir, Tapirus pinchaque (Roulin), but rather one of the lowland tapir, Tapirus terrestris (L.). We are most grateful to Craig C. Downer of the Andean Tapir Fund for pointing this out, and we would like to stress that the misidentification was not his. When we sought the photograph, Craig was happily in the field in Ecuador, and a selection of material was kindly forwarded to us by members of his family. Unfortunately, we chose the rather photogenic lowland tapirs that had been included in error. Craig rather generously points out that this is not very surprising because the species look quite alike. Two main differences are the much more prominent muscular mane of the lowland tapir, which the mountain tapir lacks, and the sparser hair of the lowland tapir, as contrasted with the thick fur of the mountain tapir. Although the lowland tapir is also substantially larger in size, the mountain tapir actually has larger feet, an adaptation to having to climb in the mountains. What is rather worrying is the fact that we have received no complaints about putting our own big feet in it ) we thus conclude that biogeographers the world over are totally confused about their tapirs! Thanks to Craig for sorting us all out – and below, we append a photograph (Fig. 1) of a genuine mountain tapir, Tapirus pinchaque (Roulin) (we hope!).


In the Kingdom of Bavaria, the capital city, Munich, created in 1873 positions as Oberlehrer – a head teacher in primary schools (Volksschulen) responsible for one school for boys and one school for girls. The mere existence of these male Oberlehrer challenged for the first time the exclusive power of Catholic and Lutheran clerics in the supervision of elementary schools. The article follows the establishment and transformations of this group of educational administrators until the final replacement of clerics in the government of primary schools in 1919. The increasing authority and influence of this group can be interpreted from the perspective of the inherent ambivalences of 'liberal governance' in education. This concept meant to govern education 'from within' – through the specialised knowledge on methods and pedagogy – and not 'from outside' – like the clerics did. Whereas expert knowledge on methods suggested a kind of direct linking to the teachers, the same expert knowledge helped the Oberlehrer to build up new hierarchies in the government of primary education.


Recent research (Choi and Nisbett 1998, 2000; Choi et al. 1999; Ji et al. 2000; Nisbett et al. 2001) has repeatedly shown that compared to Westerners, East Asians pay greater attention to situational factors and endorse a more holistic theory of causality. Based on this robust finding, the present study examined the extent to which Americans and Chinese differ in their causal judgment about, and their reaction to observed fraudulent behavior. The results show that compared to Americans, the Chinese were more sensitive to situational factors. They were less likely to attribute fraudulent behavior to individual dispositions, and less likely to agree to punitive measures that are directed at the target person. Implications for both practice and research are discussed.


Materials and Methods 6-line ferrihydrite, goethite, and hematite were synthesized and adjusted to pH 5. Samples of ferrihydrite and were spiked with goethite and hematite to make the ratios: 0% goethite/0% hematite (Fh), 4% goethite/0% hematite (4Gt), 4% goethite/3.5% hematite (4Gt/3.5Ht), and 0% goethite/3.5% hematite (3.5Ht) Samples were aged in a 90°C oven and taken out at various timepoints over a course of 6 days. After aging, the samples were dried and ground with pestle and mortar for analysis via Xray diffraction (XRD). Determining Phase Transformations Using XRD


International trade in services has been in the shadow of merchandise trade. This was not due to the negligent role of the international transactions in services, as their absolute values and dynamics have been robust. In 2017 the value of global trade in services increased 7.8 per cent and reached USD 5.4 trillion, what makes around one third of global merchandise exports (UNCTAD, 2018, p. 34). The difficulty to understand the trade in services is connected to its intangible form, technological change, and variety of modes. This unfortunately is reflected in the quality of official statistics and national and international level (Klimek, 2018). The picture becomes even more blurry when we analyse particular subcategories of services. When we move towards ABS, the issue is that they are frequently organised within enterprises, not in arm's length contracts. It makes grasping and measuring them particularly challenging. When it comes to FDI in ABS, the conventional measures fail even more than in the case of trade. The values of flows of FDI or stocks of FDI in the case of services are usually very insignificant when compared with investment in manufacturing. The second distinctive element of the analysis of FDI in services is the number of people employed. When it comes to services, there is a disproportion between the number of employees and the value of investment. In most cases, a very low investment value is reflected in the high number of jobs created. However, in some cases services are used not only for real business operations, but rather for tax optimisation. Then the value of flows is very high and the number of employees low. It should be addressed in new regulations regarding trade in services and e-commerce. But grasping all business configurations and innovations in the structure of enterprises is not possible with the current framework of public statistics. The recent developments in trade in services are highly linked with the global sourcing of business services (Lewin, 2011). It means the flows of foreign direct investment or international trade in services cannot be separated from each other. Moreover, they should not be separated from the global supply chains and the operations of MNEs. The business services are not standalone operations. They are always connected to the operations of particular firms and their decisions. Therefore it is necessary to analyse all elements of the global context to comprehend the recent developments. One more element should be linked to the development of internationalisation of business services – technology. It all creates an ecosystem for further developments of offshoring of ABS.


Epididymovasostomies and vasovasostomies were used to treat infertility in aseries of 465 men from 1964 to the present. Of the casesavailablefor follow-up, duct patency was demonstrated in 42% receiving epididymo-vasostomies and in 77% receiving vasovasostomies. The specific techniques and the reasons for failures are also discussed.


A technique for directly simulating the steady-state response of power electronic converters has been proposed. It is based on the representation of circuit elements by impedance or admittance matrices for periodic waveforms. A Newton–Raphson procedure is then used to solve the non-linear circuit equations. Detailed semiconducting device models may be easily included in the computations. The responses of typical power electronic converters have been computed and their waveforms have been presented. The technique is able to simulate non-autonomous and autonomous circuits.


JNFECTIOUS disease does not play the dominant part on the medical stage that it did a generation ago. Since then much knowledge regarding disease in the individual, rather than that of the mass, has been acquired. Nevertheless, the fact remains that, although the microbic aspect of disease has lost some of its stimulating influence on research, the organisms are still with us and cast their myriad shadows over every department and specialty of medical practice.


A refillable pencil, in particular a soft lead pencil, has a sleeve-shaped shaft (1) with a front and a rear end, a pushing rod (3) coaxially arranged in the shaft (1) and fixed at one end to the rear en of the shaft, seen in the axial direction, a lead (5) joined to the free end of the pushing rod (3) and a sleeve-shaped front part (2) which encloses the lead (5) over at least part of its length. The front part co-operates with the shaft in the manner of a helical gear and can be retracted therein when rotated relative to the shaft (1). This soft lead pencil is characterised in that the lead (5) is rotatively joined to the pushing rod (3).


Single crystals o f MnIn2Se4 have been grown by the chemical vapour phase transport technique using A1C13 as the transporting agent.

Snails, Goniobasis livescens (Menke), were exposed to acutely sublethal concentrations of p-nitrophenol and the lampricide, 3-trifluoromethyl-4 nitrophenol (TFM), and then to acutely lethal thermal shocks. The same species were also exposed to acutely sublethal concentrations of zinc followed by exposure to acutely lethal concentrations of p-nitrophenol; and to acutely sublethal concentrations of TFM followed by exposure to acutely lethalconcentrations of zinc. Brown trout, Salmo trutta, were exposed to acutely sublethal concentrations of TFM and then to an acutely lethal thermal shock. Results of these experiments indicate that prior exposure to acutely sublethal toxicant concentrations may reduce survival time for a subsequent exposure to acutely lethal concentrations of a second toxicant, but neither prior nor concomitant exposure to acutely sublethal toxicant concentrations ensures that the median survival time for a lethal exposure will be significantly altered. The brown trout exposed to an acutely sublethal concentration of TFM and then an acutely lethal thermal shock did have significantly altered survival patterns.

Introduction Processes of international cooperation and regional integration in various parts of the world reflect the simultaneous influence of globalization and regionalism, but difer in their level of development, degree of participation and scope of questions discussed. Although various factors are involved, they are analyzed through the same two models of international cooperation: the rational choice model and the normative model. The rational choice model is based on the premises of actors' individualism, egoism and rationalism. Rational choice means ability to receive al information necessary for decisionmaking, the capacity to efectively analyze this information, and rationaly choose the most profitable option. To some extent those conditions can be fulfiled, however as regional cooperation progresses, irational factors of interaction also appear and develop such as trust, colective consciousness and an awareness of common interests. These factors form the basis of the normative model of cooperation. The active use of a transnational identity (synonymous to colective consciousness) among Scandinavian countries in Europe ilustrates that people's awareness of a common fate, notions of belonging to the same political, economic, social and cultural space and working towards a common goal, leads to economical and political integration in the long run. The Scandinavian economic model represents a developed market economy with a mature social infrastructure. The state redistributes income received in the private sector through a tax system, but does not produce GDP itself. The state also controls the private sector and develops long-term economic strategies. The Scandinavian economic model turned out to be one of the most stable not only during the 20th century, but also throughout the global financial crisis in the beginning of the 21st Yulia Lamasheva:Cultural Background and International Economic Cooperation: Comparative Analysis for Scandinaviaand Northeast Asia 155


In this study we investigate the scientific production on Cloze test, between the years 2002 and 2012. Fourteen journals were used, from which 32 articles were analyzed on the basis of certain criteria set by Witter and others considered relevant by the author. The data evidenced an increase in publications since 2007. The years 2007 and 2008 were the most productive. The research report was the most used form and the southeastern region the one which most published in that period. There was still the predominance of multiple and feminine authorship and studies that employed other tests to the Cloze, and therefore revealed a relationships with other constructs. The results also pointed to the predominance of research in educational context with university student, based on the use of traditional technique, with the deletion of every fifth word of the text and literal correction.


In this paper, issues associated with the use of the OTV (Ozone Tagging Velocimetry) technique for nonintrusive unseeded instantaneous flow velocity measurements in laboratory conditions have been investigated. Instantaneous ("single-shot") OTV measurements have been demonstrated in low speed air flows. OTV photochemistry has been presented, and the effects of temperature and pressure on ozone concentration levels have been discussed. Spatial resolution issues have been investigated. The results prove that the use of two narrowband injection locked tunable excimer lasers produce the highest contrast and signal-to-noise (S/N) ratio. The effects of molecular diffusion on velocity measurement accuracy and flow tag detectability are discussed.


This review analyzes the prevalence of obesity among the adult population in the Russian Federation. The data of various studies, including large international projects (WHO MONICA 1985–1995, HAPIEE 2003–2005), all-Russian screenings (RLMS - HSE 1993, Federal monitoring of arterial hypertension 2003, ESSE-RF 2013 — present.), as well as selected regional studies. In some regions, the long-term dynamics of obesity has been studied. The history of studying the epidemiology of obesity in Russia has more than thirty years. According to the data obtained, the prevalence of obesity throughout the country remains high and continues to increase. Thus, among men, the prevalence increased from 10.8% in 1993 to 27.9% in 2017, among women — from 26.4% to 31.8%, respectively. In all regions where it was possible to assess long-term trends, the prevalence of obesity among adults increased (maximum — 48.5% in the Belgorod region). In the adult population, obesity is more common in women (maximum — 47.0% in the Novosibirsk region) than in men (maximum — 30.0% in Ivanovo and Voronezh regions). It is necessary to expand the number of regions in Russia in which studies of the prevalence of obesity are carried out, as well as to strengthen measures to combat overweight and obesity in all age groups throughout the country.


Probiotics are useful organisms in preventing the spread of disease in aquaculture. Therefore this study aims to evaluate the effect of administering Bacillus NP5 on the growth, survival rate, and histology of catfish with Aeromonas hydrophila infection. To achieve this, catfish (7.75 ± 0.02 g) were reared for 45 days with a density of 20 per tank. Furthermore, the study consisted of 4 treatments and 3 replications, namely K+: 0% Bacillus NP5+0.1 mL A. hydrophila injection, K-: 0% Bacillus NP5 + without A. hydrophila injection, A: 0.3% Bacillus NP5, and B: 0.8% Bacillus NP5. The results showed that the addition of probiotics significantly increased the growth and survival rate of catfish (P <0.05) compared to K+. The higher value of specific growth rate was found in treatments A and B (0.22 ± 0.03 and 0.23 ± 0.03% day-1, respectively) and the lowest in K+ (0.14 ± 0.03% day-1). Also, the tissue damage in K+ was higher than in the probiotic treatment. Besides, hyperplasia, congestion, and secondary lamella fusion in the gill tissue were found in the K+, while other treatments were found only in hyperplasia. Melanomacrophages occurred in catfish kidney tissue for all treatments, however, hydropic degeneration was found in the control treatment. The addition of Bacillus NP5 in feed resulted in higher growth, survival, and tissue damage compared to K+. Also, the addition of 0.8% Bacillus NP5 resulted in less catfish tissue damage.


The contribution from both surface roughness and matedness in the peak shear strength of rock joints is not yet well understood. To be able to account for the influence of matedness on the peak shear strength of rock joints, both surface roughness and aperture need to be considered. Technical developments over the past few decades have shown that both surface roughness and aperture can be accurately measured using optical scanning. This technique has been utilized to account for surface roughness parameters in various shear strength criteria that assume a perfect match between joint surfaces. This paper investigates and compares the capabilities of two shear strength criteria to predict the peak shear strength of rock joints with different matedness. The analysis performed shows that both approaches have their strengths and limitations. For instance, accounting for the matedness of unmated rock joints based on their surface aperture gives better predictions of the peak shear strength. On the other hand, accounting for shearing failure mode becomes relevant at high normal loads. A possible way forward to reduce the limitations of these criteria could be to combine their strengths.


Aminodeoxycelluloses were prepared by treating cellulose ρ-toluenesulfonates, which were prepared from various kinds of cellulose samples under various conditions, with a solution of ammonia in ethanol at 100° in an autoclave. From cellulose ρ-toluenesulfonates made at 0°, from never-dried, solvent-replaced regenerated cellulose, aminodeoxycellulose with a high degree of substitution (up to 0.82) was obtained with minimum side reaction. Acetylation and 2, 4-dinitro-phenylation of aminodeoxycellulose were studied. Some properties of aminodeoxycellulose are also reported.


Many large-scale phenomena in our Universe, such as gravitational waves, are challenging to reproduce in laboratory settings. However, parallels with condensed matter systems can provide alternative routes for experimental accessibility. Here we show how spin nematic phases provide a low-energy avenue for accessing the physics of linearized gravity, and in particular that their Goldstone modes are relativistically-dispersing massless spin-2 excitations, analogous to gravitational waves. We show at the level of the action that the low-energy effective field theory describing a spin nematic is in correspondence with that of linearized gravity. We then explicitly identify a microscopic model of a spin-1 magnet whose excitations in the low energy limit are relativistically dispersing, massless spin-2 Bosons which are in one-to-one correspondence with gravitational waves and, supported by simulation, outline a procedure for directly observing these analogue waves in a cold gas of $^{23}$Na atoms.

ABSTRACT The most important goal in cotton breeding is to increase the fiber yield which can be increased by improving a key trait, lint percentage (LP). However, narrow genetic background of upland cotton resulting in stagnant yield. In order to effectively dissect the genetic mechanism and enrich the gene loci of LP in cotton, the genetic diversity and population structure and a genome-wide association study (GWAS) was conducted using 204 upland cotton accessions based on 191 pairs of polymorphic microsatellite markers. The results were as follows: (1) The agronomic traits of the materials especially LP varied widely. (2) The SSRs revealed relatively high degree level of genetic diversity at DNA level. (3) Similarity coefficient cluster analysis of SSR markers indicated the influence of male parent on female parents was different after cross, the variation sites of agronomic traits could be further excavate in F1. (4) The GWAS revealed that 3 SSR markers were associated with LP: BNL3649-2, GH0132-2, CIR0246-3. There were two genes, Gh_D02G0125 and Gh_D11G2610, near the three SSR loci. These results provided a theoretical basis for improving fiber yield.

This article discusses federal and international requirements for maritime security training and how the U.S. Coast Guard is working to meet these requirements. The Coast Guard has partnered with the Maritime Administration and the United States Merchant Marine Academy to develop model maritime security training courses and tables of competence, and a voluntary maritime security training course approval program. Internationally, there have been several recent developments with respect to maritime security training. The International Maritime Organization has developed mandatory training requirements for ship security officers and has published guidance on company security office training requirements. The Code of Federal Regulations Subchapter H implements the Maritime Transportation Security Act of 2002, which in turn mandates the education, training and certification of maritime security personnel. The Coast Guard will implement new international requirements and guidance when Subchapter H is revised, although no timetable has been set for this revision.


A quick and convenient method has been developed for determination of some antibiotic drugs in low concentration. Aliquots containing 1-5 mg of the antibiotics are allowed to react with 3 x 10 - 2 N pyridinium chlorochromate (PCC) in the presence of 5 N H 2 SO 4 for 5-60 min at RT (25-30"). After the reaction is over, the unconsumed reagent is back determined iodometrically. The value of % error, SD and CV prove the method to be precise and reproducible.


A stellarator experiment with quasi-toroidal magnetic symmetry has been designed based directly on the recent concept of Garabedian. The experiment will test the reduced neoclassical ion transport and plasma viscosity expected of the nearly symmetric configuration. The chain of islands at the plasma edge will be exploited as a helical island divertor. The application of ohmic current to evaluate disruptions in hybrid operation is under consideration, and a test of the stability beta limit of this new configuration is also feasible in this device.


Ozonation combined with UV irradiation (UV/O3) is an advanced oxidation technique that is very promising for the destruction of organic compounds in aqueous solution. In this study, chlorophene was chosen as a model substrate to investigate the effects of pH, initial substrate concentration, ozone dose, and UV light intensity in degradation experiments. The pseudo–first-order rate constant for total organic carbon (TOC) removal was 2.4 × 10−2, 9.8 × 10−4, and 6.4 × 10−2 min−1 for O3, UV, and UV/O3 treatment, respectively. Clearly, UV-enhanced ozonation leads to a synergetic increase in the overall degradation efficiency. Comparative experiments were performed to investigate the effect of the matrix (distilled water or sewage) on chlorophene removal. The organic compounds in sewage retarded the rate of chlorophene removal by 38%, probably by competitively reacting with the oxidizing agent and screening light. The compound 2-benzoylbenzo-1,4-quinone, benzo-1,4-quinone, hydroquinone and maleic acid were identified as primary intermediates by gas chromatography-mass spectrometry. The concentrations of acetic, formic and oxalic anions were detected by ion chromatography. A possible degradation pathway is proposed on the basis of the reaction products identified.


Based on the Artificial Soil Test,acute toxicities of combined two pollutants among chloride cadmium,malathion and acetochlor with 5 different ratios are tested on Eisenia fetida earthworm.The results show that interactions between two pollutants in each group are almost antagonistic.The interaction between 19.46 mg·kg-1 of cadmium and 175.15 mg·kg-1 of acetochlor in the ratio of 1︰9 is,however,an additive effect.This indicates that the eco-toxic effect of combined pollutants is related with the chemical characteristic and concentration of the pollutants.In the combined contamination test,the effect of each pollutant on the growth of earthworm is similar to its independent effects.The toxicities of the 3 pollutants respectively rank from serious to light for malathion,acetochlo and cadmium.


The shear failure of the whole soil-structure interface is regarded as the combination of the failure of finite micro cells based on the randomicity of the shear strength and the shear deformation characteristics under 0.8~1.0 MPa normal stress condition.The shear strength expression of the micro tiny cells on the soil-structure interface was proposed in terms of the Mohr-Coulomb criterion under plane strain condition.The statistical damage softening constitutive model of the soil-structure interface was established based on the double-parameter Weibull random distribution for the shear failure of finite micro cells.The results show that the model can simulate the whole failure process of the soil-structure interface,especially in those case that the characteristics of strain softening is prominent during the shearing process.The correlation coefficient of the model and experimental curves is more than 0.99.


By means of the present invention condensation water generated upstream from a compressor is made to flow into a groove (44) and is retained temporarily. The condensation water flowing into the groove (44) moves in the direction of gravitational force (in other words, toward an air bypass valve (ABV) (38)) within the groove (44). When the ABV (38) is opened, the condensation water that has accumulated in the groove (44) is carried along with the flow of a return gas and is blown into the center part of an inlet (46), and then flows from the center part (42b) of the front surface of an impeller (42) to the interior of the compressor (20), together with the intake air flowing in the center part of the inlet. The center part (42b) has a lower circumferential speed than an outer circumferential part (42a), so erosion due to contact with the condensation water can be more easily prevented at the center part than at the outer circumferential part (42a).

Close-coupling calculations have been performed to investigate the formation of three-particle bound states in a model collinear system. A generalization of Levinson's theorem (1966) is employed to determine the critical potential strengths necessary for the existence of the triatomic states. The system consists of an atom interacting through a Morse potential with a diatomic molecule bound by a harmonic potential. Comparisons are made with classical phase-space and S-matrix theory and with quantum-mechanical variational and perturbation calculations. When only a few bound states are involved it is shown that the quantal approximations are more accurate than the classical results.

Immediately after the operation the hypersomnolence disappeared, the breathing became normal, and the disturbing snoring at night ceased.


The paper focuses on extending traditional Total Site Integration methodology to produce more meaningful utility and heat recovery targets for the process design. The traditional methodology leads to inadequate results due to inaccurate estimation of the overall Total Site heat recovery targets. The new methodology is a further development of a recently extended traditional pinch methodology. The previous extension was on the introduction of using an individual minimum temperature difference (ΔTmin) for different processes so that the ΔTmin is more representative of the specific process. Further this paper deals with stream specific ΔTmin inside each process by setting different ΔT contribution (ΔTcont) and also using different ΔTcont between the process streams and the utility systems. The paper describes the further extended methodology called stream specific targeting methodology. A case study applying data from a real diary factory is used to show the differences between the traditional, process specific and stream specific total site targeting methodologies. The extended methodology gives more meaningful results at the end of the targeting with this avoiding the over or under estimated heat exchanger areas in the process design.


Summary.  'Delete = replace' is a powerful and intuitive modelling identity. This paper extends previous work by stating and proving the identity in more general terms and extending its application to deletion diagnostics for estimates of variance components obtained by restricted maximum likelihood estimation for the linear mixed model. We present a new, fast, transparent and approximate computational procedure, arising as a by‐product of the fitting process. We illustrate the effect of the deletion of individual observations, of 'subjects' and of arbitrary subsets. Central to the identity and its application is the conditional residual.

A 20-month-old boy was brought in to the clinic because he was vomiting. Two nights before, the child had fallen down some stairs. Dr. Perri Klass writes about the worry that set in after she saw the boy and about the voices that can echo in your head after even a simple clinical decision.


Main purpose of this research was to study the effects of Dunaliella microalgae on immunological and survival changes of the rainbow trout. It was planned to measure the amount of IgM blood immunoglobulin and find out the occurred changes in survival rate of the fish. Rainbow trouts were separated in five groups and were fed with diets containing 0., 5,7 ,9 and 11 grams of pure dried Dunaliella in each kilogram respectively Blood samples were taken from 25 random collected fish, at the end of first and third months of culture and were send to the laboratory to measure immunoglobulin factor. Results indicated that the levels of IgM immunoglobulin in the blood pelasma of those fish fed with Dunaliella aglae had meaningful statistical differences (P<0.05) with those not received any Dunaliella alage. With the increased levels of Dunliella in food, and increased weight, levels of IgM immunoglobulin were also were also increased. Their measured amounts were 10± 1 miligram per deciliter of blood pelasma respectively. No mortality was observed in any of the groups, showing good adaptation with feeding conditions. Paying attention to the obtained results, indicate that Dunaliella aglae containing βcarotene, has favourable effects on immunology, survival and growth of rainbow trout.


Skull feature points play an important role in computer-aided craniofacial restoration. An improved relative angle histogram algorithm is proposed to match the feature points of the skull, aiming at the low positioning accuracy of the existing skull feature point matching algorithm and the difference of the number of points and the difference of the distribution of the model points. First, the Iterative Closest Point (ICP) algorithm is used to register the original skull model. Then, a new spindle is established for the model after registration. The relative angle of the model points is calculated and the phase diagonal distribution of the model points is calculated. Finally, the model points which are most similar to the histogram distribution of the model feature points are selected as the matching points. Experiments show that the algorithm has achieved good results in the matching of feature points of the skull model.


The derivations of existing error bounds for reduced order models of time varying partial differential equations (PDEs) constructed using proper orthogonal decomposition (POD) have relied on bounding the error between the POD data and various POD projections of that data. Furthermore, the asymptotic behavior of the model reduction error bounds depends on the asymptotic behavior of the POD data approximation error bounds. We consider time varying data taking values in two different Hilbert spaces $ H $ and $ V $, with $ V \subset H $, and prove exact expressions for the POD data approximation errors considering four different POD projections and the two different Hilbert space error norms. Furthermore, the exact error expressions can be computed using only the POD eigenvalues and modes, and we prove the errors converge to zero as the number of POD modes increases. We consider the POD error estimation approaches of Kunisch and Volkwein [SIAM J. Numer. Anal., 40 (2002), pp. 492--515] and Chapelle, Gariah, an...


Utilizing first‐principle calculations, two systems of graphene/overlay are investigated. The overlays are made up of a self‐assembling molecular network (SAN) that introduces local electric fields in opposite directions on graphene. It is demonstrated that the patterned electric field via dipolar SAN, in addition to gating, can create a gap in graphene's band structure. Also, linearly dispersing bands of graphene are retained intact in a certain energy window in the vicinity of the Dirac point. Electronic gaps of 254 and 263 meV appear in the band structure of graphene. And the Fermi levels fall in the middle of the generated electronic gaps. The occurred shift through gating in the density of the state of graphene is detected by means of scanning tunneling microscope images, where the images distinguish the intact density of states from those affected by the dipolar overlay.
