This paper describes preliminary discussions on manufacture of a He-Ne laser and investigation of output characteristics. The He-Ne laser which is to be manufactured is what is the most common wavelength λ=632.8[nm] transition in the red portion of the spectrum. The output characteristics as various parameters, such as gas mixture ratio, gas pressure, discharge current, resonator length, and the efficiency characteristic as a input power will be investigated.


In light of the problem that the rudaceous coal-bearing soil which ranges along with Guangzhou-Wuzhou Expressway can't content for soil subgrade filler claim,two improvement schemes of the soil by respectively mixing quicklime and cement are put forward and improvement tests are accordingly taken for contrasting study according to the results of test in laboratory.The result indicated that the effect by mixing cement is evidently better than that by mixing quicklime of the rudaceous coal-bearing including consolidation properties,California bearing ratio(CBR),water stability,etc.;its shear strength properties,unconfined compressive strength and resistance deformability are all evidently increased by mixing cement;in factors effecting strength of the rudaceous coal-bearing soil,cement mixing ratio is the most salient,followed by age and water content,and a fitted formula which is affected by multi-factors is put forward according to the test result of unconfined compressive strength.The rudaceous coal-soil which is mixed with about 3 percent cement is entirely able to meet the claim for subgrade filler,which offers useful reference to roadbed treatment in coal-bearing soil region.


SIR FRANCIS BACON once said: &dquo; Read not to contradict and confute; nor to believe and take for granted ; nor to find talk and discourse ; but to weigh and consider,&dquo; and to-day it is my intention to discuss some of those anomalies and difficulties which have become apparent throughout the years in the practical issues of port health administration, and to offer certain suggestions for your consideration. My remarks and views will be of a general nature, and whilst it is our experience that we obtain most ready co-operation and help in our work from nearly all concerned, it is nevertheless true that there is no all-embracing uniformity, and the problems which I shall discuss are those which have presented themselves or are likely to do so. Further, though great and rapid advances have been made in the hygienic conditions of ships, and also, if I may say so, in the social welfare of those who live and work at sea, yet there are still many ships whose standards for health and comfort fall far below those which are desired, especially so in the veterans of the service.


Theology is an effort to contextualize religious teachings, not just textualizing, to answer human problems, not only problems of faith, monotheism but also cultural problems, problems of daily life, where the problems faced by humans are never-ending. In the context of Islam, the word theology will be more precise and meaningful when it is associated with the word Islam, so that the understanding of theology in question is theology that breathes Islam. An understanding of educational theology, in fact requires the inclusion of the conception of education and or deriving the concept of education in and from the schools of mutakallimin thought. Education is an interaction, namely the process of giving and taking, between humans and the environment. It is a process by which humans develop and create the skills needed to change and improve human conditions and their environment, as well as the formation of attitudes that guide their efforts to rebuild their human and physical characteristics. Education in Islam is often interpreted as At. Tarbiyahi (Education), the meaning is very thick and related to ar-riyadhah (practice). The training in question includes physical and spiritual training. The purpose of Islamic education is the formation of students to become servants of Allah who are pious and responsible for carrying out worldly and ukhrawi work.


This article explores the ways in which feminist sociolinguistic studies and feminist translation studies can inform and empower each other in terms of theory, practice, and research. While the discussion of the theoretical intersection between the two fields focuses on the feminist critiques of sexist language from the perspective of language philosophy, the second part on how the fields intersect on a pragmatic level is more specific and focuses on the critique of the so-called 'generic' masculine nouns and pronouns. The third part argues that both fields would benefit from a research-based cooperation and discusses how such a cosupportive relationship can be built. By presenting an overview of such interconnections, the article aims not only to expand related scholars' interdisciplinary understandings of gender dynamics with regard to language and translation, but also to provide them with a springboard to initiate cross-disciplinary dialogues. The teaching and learning guide, by presenting ideas on how to apply the multiple intersections between feminist translation and feminist sociolinguistics in classroom contexts, extends the article's scope by highlighting how these fields could further be interconnected through pedagogy.


Based on the commonly used response caudron in industrial production, a fuzzy self-regulation PID controller which realized the temperature control method in polyreaction is proposed and the PID controller parameter on line from the adjustment, improved its performance and increased the precision.The simulation result shows that the fuzzy self-regulation PID controller has good compatibility to the controlled system, with good robustness, small overshoot and short reponse time which can well satisfy the requirement in the actual control process.


In microwave-assisted magnetic recording (MAMR), the frequency selection of the assisted microwave magnetic field is important. In this paper, we set up a micromagnetic model of [CoX/Pt]4 media with a different anisotropy configuration to study the frequency selection based on media signal-to-noise ratio (SNR) by the simulation of writing performance. By evaluating each layer's SNR, we find that the four-layer integrated SNR-<inline-formula> <tex-math notation="LaTeX">$f$ </tex-math></inline-formula> relationship is more influenced by the top two layers, and the interlayer exchange coupling strength plays a dominant role on the consistent SNR-<inline-formula> <tex-math notation="LaTeX">$f$ </tex-math></inline-formula> curve in each media layer. When Hiec = 2000 Oe, the optimum frequency in each layer is coherent; when Hiec = 1000 Oe, the optimum frequency has a 2 GHz difference in four layers. When the average anisotropy field <inline-formula> <tex-math notation="LaTeX">$H_{k}$ </tex-math></inline-formula> is in a range of 19–25 kOe, the integrated optimum frequency <inline-formula> <tex-math notation="LaTeX">$f_{\mathrm {{op{-}all}}}$ </tex-math></inline-formula> with highest media SNR increases versus <inline-formula> <tex-math notation="LaTeX">$H_{\mathbf {k}}$ </tex-math></inline-formula> with a slope of 1.87 GHz/kOe, smaller than the ferromagnetic resonant frequency coefficient of around 3 GHz/kOe, which is beneficial for MAMR applications. With optimized intergrain exchange strength <inline-formula> <tex-math notation="LaTeX">$A_{\mathrm {gb}} = 0.25$ </tex-math></inline-formula> and optimum frequency <inline-formula> <tex-math notation="LaTeX">$f_{\mathrm {op}} = 23$ </tex-math></inline-formula> GHz, an areal writing density limit of 3 Tbit/in2 can be achieved.


Basilar artery thrombosis accounts for a small part of ischemic strokes but contributes to one‐fifth of the posterior circulation strokes. Recurrent basilar artery thrombosis secondary to dolichoectasia is caused by abnormal flow in the dilated artery and can result in cerebral ischemia. We present a similar case of recurrent thrombosis with a missed dose of anticoagulation and dehydration on two separate occasions.

 An 81‐year‐old man with a past medical history of ulcerative colitis with colostomy, provoked deep venous thrombosis presented as a transfer from an outside hospital with acute onset of dysarthria, nausea/vomiting, unsteadiness, and left hemiparesis. CT angiogram of head and neck revealed right vertebral thrombosis extending into the basilar artery with dolichoectasia involving distal right vertebral artery and basilar artery. He was started on heparin infusion with improvement in symptoms and a return to baseline. He was later transitioned to apixaban and discharged home. On a follow‐up office visit two months later, his repeat CT angiogram revealed resolution of the thrombus. He was advised to continue the medication due to the risk of recurrent occlusion secondary to vessel anomaly. After four months, the patient returned to the emergency department with acute onset dizziness, imbalance, nausea, and vomiting. CT angiogram of the head and neck was performed which revealed non‐occlusive thrombosis in the basilar artery. On evaluation by neurology, he admits to three missed doses of apixaban. Clinical and laboratory data were concerning for volume depletion. On further questioning about his symptoms, he mentions decreased oral intake on the day of colostomy change. He was advised to continue apixaban and stay hydrated.

 After fifteen months of the first presentation, the patient is symptom‐free but was continued on anticoagulation with apixaban to prevent recurrent events.

 The role of short‐term and long‐term anticoagulation in basilar artery occlusion is less studied. No prospective trials were done so far to suggest that antithrombotic therapy lowers the risk of recurrent ischemic events and/or anticoagulation is superior to antiplatelets. Dolichoectasia by itself can increase the risk of recurrent thrombosis and dehydration likely facilitated the thrombosis in our patient during the event of missed anticoagulation.


First principles calculations, based on density functional theory (DFT) with ultra‐soft pseudo potentials were performed to simulate the electronic, magnetic and crystallographic structure and elastic properties of RbNiF3, a candidate for magneto optical applications. The transparent magnetodielectric RbNiF3 is of interest because in contrast to the majority of other ABF3 compounds, which are orthorhombic perovskites, it is a representative of a much smaller group of chalcogenides with hexagonal crystal symmetry. In fact, this is the structural phase at normal pressure and it is isomorphous with the hexagonal modification of BaTiO3. The compound becomes ferrimagnetically ordered below a Neel temperature reported as 135 K. Synthesis at elevated temperature and pressure yields another phase that is a cubic perovskite (a0 = 4.077 Ǻ), reported as antiferromagnetic. Computer simulations were performed using the generalized gradient approximation exchange‐correlation functional with included Hubbard correction ...

October December 2016 2401 JCPS Volume 9 Issue 4 Design of CMPFFE in current mode signalling for high performance and low power Dr.J.Jebastine, Francis Mary.T 1 ECE Department, Jeppiaar Engineering College, Chennai, India VLSI Design, Jeppiaar Engineering College, Chennai, India *Corresponding author: E-Mail: firstname.lastname@example.com ABSTRACT Low power is the major theme for electronics industry. An enormous portion of the on chip power is used by clock distribution network and flip-flops is made by clock system. The low power has caused a significant pattern shift where performance and area is main consideration for power dissipation. The substantial users of this power clock distribution networks (CDNs), global buses and synchronous signals. A new paradigm for clock distribution uses current rather than voltage to reduce power. This clock distribution network has been distributed to the one to many networks. One-to-one signals has been used in Current-mode (CM) signaling, this is the first manipulation in a one-to-multiple clock distribution network. To overcome this, we proposed a new high-performance current-mode pulsed flip-flop with enable (CMPFFE) using 180 nm CMOS technology. The CMPFFE also eliminates the need for complex CM receiver (Rx) circuitry and/or local VM buffers is used in conventional CM signaling schemes. To reduce the clock loads from the signal transmission circuits positive edge triggered signal is used. The design is carried out in Tanner EDA tool and the simulation results are based on 180nm technology for low power dissipation based flip-flop.

Evaluation of indoor radon level and its health risk parameters has been carried out in three communities Azuabie, Trans-Amadi and Nkpogu towns in Port Harcourt, Rivers State, Nigeria. A pocket sized Corentium Arthings digital radon detector meter was used to record the indoor radon concentration levels. The geographical coordinates were recorded using a hand-held geographical positioning system (GPS) for the various sample points. A total of 30 sample points were evaluated, with 10 sample points for each town respectively. The results of the concentration levels showed that for Azuabie (AZ) town, the concentration level varied from 6.660 Bqm -3 to 13.690 Bqm 3 with an average of 10.65±0.95Bqm. Nkpogu (NK) town the results of the indoor concentration level ranged from 9.250 Bqm -3 to 18.870 Bqm -3 with an average of 13.32±1.02 Bqm -3 , Nkpogu (NK) town, the indoor concentration level ranged from 7.030 Bqm -3 to 20.350 Bqm -3 with an average of Original Research Article Briggs et al.; AJOPACS, 9(2): 25-35, 2021; Article no.AJOPACS.67820 26 12.25±1.34Bqm. The annual absorbed dose for Azuabie, Trans-Amadi and Nkpogu varied as follows, 1.680 mSvy -1 – 3.921 mSvy -1 , 2.334 mSvy -1 – 47610 mSvy -1 and 1.774 mSvy -2 – 5.134 mSvy respectively. The annual effect dose rate for the three towns ranged from 0.403 mSvy – 0.941mSvy -1 , 0.560 mSvy -1 1.143 mSvy -1 and 0.426 mSvy -1 – 1.143mSvy -1 . The excess life time cancer risk varied from 1.4117 – 3.294, 1.9607 – 3.999 and 1.4901 – 3.999 respectively. The results of the indoor concentration levels annual and the absorbed dose and the annual effective dose rate are all below the ICRP safe limit. However, the results of the excess life time cancer risk are all higher than the ICRP safe standard limit of 0.029×10.


Abstract: Possibility of determination of Cu(II) at antimony modified carbon paste electrode and its application in determination of trace amount of copper in real sample has been investigated. According to obtained results, it was found that SbF-CPE can be used for these purposes successfully. Both detection limit of 1.45 ppb (evaluated as 3σ) and RSD 4.8 (for 10 ppb Cu and 10 different measurements) were also evaluated. Antimony-based electrodes are environmentally friendly which is their most important advantage rather than mercury-based ones. BiFEs have been used for determination of copper before but because of decrease of the Bi peak with increasing Cu(II) concentration which causes irreproducibility. As known, it was solved by additions of high concentration of a gallium salt or hydrogen peroxide. Using this antimony film electrode, no addition of other chemicals was necessary.


Financial statement information is useful for investors to predict the future investment returns, in turn the fact that capital markets corresponds with such financial information, accordingly (Merton, 1987). Regardless of the current good news or bad news of a company extracted from financial statements, it can also assist investors to anticipate future firm financial and market performance. Financial statements are highly informative surrogate and also regarded as the most transparent, accurate, and persistent disclosure vehicle outside. It can therefore convey a lot of information to decision makers. Furthermore, financial statement is still useful information even though it does not directly provide cash flow information (Kim and Kross, 2005; Ball and Shivakumar, 2006), implying that those guys realise income statement and balance sheet information can delivery certain important message to external investors. The difference between the net income and operating cash flow is the accrual. Financial statements are provided in accrual basis which seemingly is useful for decision makers. Dechow (1994) provides consistent evidence that the net income is more explaining the share movement than operating cash flow and net cash flow. Decision makers would update their subjective investment return predictions when new information releases (SFAC 1; IASB Framework; CICA handbook). The extent of informativeness of the financial statements depends on mainly both relevance and reliability drivers (SFAC 2), both of which are critical factors for the capital markets operating in a more efficiently and effectively manner.


OBJECTIVE To study the detection rates and genotype distribution of blaCTX-M-9 group extended spectrum β-lactamases(ESBLs) in Escherichia coli(E.coli) clinical isolates.METHODS One hundred and forty-five E.coli isolated between 2005 and 2006 were collected,Double-disk synergy test was used to detect ESBLs,and the blaCTX-M-9 group ESBLs genes were detected by polymerase chain reaction(PCR).The genotypes of β-lactamases and mutation sites were confirmed by sequencing of the PCR products.RESULTS Among 145 E.coli strains,114 strains(78.6%) carried the genes of blaCTX-M-9 group,60 strains(82.2%) of 73 strains in 2005 and 54 strains(75.0%) of 72 strains in 2006.All positive strains were the CTX-M-14-type.25 strains of E.colI in CTX-M-14 gene find five point mutations,lead to 80,158,242,275 bits amino acid changing.CONCLUSION The prevalence of blaCTX-M-9 group ESBLs in this hospital is high and the horizontal transmission of ESBLs is serious among the clinical E.colI isolates.The CTX-M-14 is the dominant epidemic type in this hospital,including the change of the corresponding amino acid sequence.


This study's objective was to separate cellulose, hemicellulose, and lignin after high-pressure supercritical carbon dioxide pretreatment for further valorization. The study investigated the supercritical carbon dioxide pretreatment of apple orchard waste at temperatures of 160–200 °C, for 15–45 min, at a pressure of 10 MPa. Response Surface Methodology (RSM) was used to optimize the supercritical process and to improve its efficiency. The change of functional groups during different pretreatment conditions was examined by Fourier transform infrared (FTIR) spectroscopy. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) confirmed the structural changes in the biomass structure before and after pretreatment. A new ultra-high performance liquid chromatography (UHPLC) coupled with an evaporative light scattering detector (ELSD) method was developed and validated for the determination of carbohydrates in the liquid fraction that resulted after pretreatment. The estimated uncertainty of the method ranged from 16.9 to 20.8%. The pre-treatment of high-pressure supercritical CO2 appears to be an effective and promising technique for the recovery of sugars and secondary by-products without the use of toxic solvents.


While I agree with the article 'Politically adept' (Options September 27), I believe there is another greatly underused influential mechanism.


THE RESULTS OF THE INITIAL THREE YEARS OF CONTINUING RESEARCH PROJECT ON THE DURABILITY OF CONCRETE BRIDGE DECKS IN PENNSYLVANIA ARE PRESENTED. THE STUDY INVOLVED FIELD SURVEYS OF 38 BRIDGE DECKS COMPRISING 2,782 TEN-FT LONG SURVEY UNITS. A TOTAL OF 154 CORES WERE TAKEN FROM 34 OF THE DECKS. THE CORES WERE SUBJECTED TO DETAILED LABORATORY ANALYSES INCLUDING DETERMINATION OF AIR VOID PARAMETERS BY LINEAR TRAVERSE TECHNIQUES, WATER CEMENT (W/C) RATIO DETERMINATIONS, AND PETROGRAPHIC EXAMINATION. SEVEN BRIDGE DECKS WERE OBSERVED DURING CONSTRUCTION TO EXAMINE AND EVALUATE THE EFFECT OF CONSTRUCTION PRATICES ON DURABILITY. BRIDGE DECKS WERE RESURVEYED ANNUALLY TO ESTABLISH RATES. THE MAJOR TYPES OF DETERIORATION FOUND WERE TRANSVERSE CRACKING, FRACTURE PLANES, POTHOLES, AND SURFACE MORTAR DETERIORATION. THE PRIMARY CAUSES OF DETERIORATION WERE INDICATED TO BE MATERIALS (AGGREGATES) AND WORKMANSHIP (OVERFINISHING, POOR QUALITY CONTROL WITH RESPECT TO ENTRAINED AIR AND W/C, AND IMPROPER PLACEMENT OF REINFORCEMENT). RECOMMENDATIONS TO ALLEVIATE THE CAUSES OF POOR PERFORMANCE AND SUGGESTED AREAS OF NEEDED RESEARCH ARE INCLUDED. /AUTHOR/


In fusion research, data analysis typically needs to combine different information at different levels of uncertainty: experimental data, physics quantities, constraints and technical parameters enter the analysis process which must result in a picture compliant with physics considerations. Beyond the combination, weighting different sources of information is a prerequisite to derive errors and to assess the quality of measurements to be sufficient to verify or to falsify physical models.


In order to prepare new potential therapeutic agents,chelation between antimony and various complexones was studied.It was reported by Schwarzenbach et al that the calcium chelate of cyclohexane-1,2-diaminetetraacetic acid (Ⅱ) was more stable than the corresponding chelate of ethylenediaminetetraacetic acid (Ia).Since the introduction of substituents on the carbon chain of Ia might render the chelates more stable and thus reduce the toxicity of the metallic compounds,it would be advisable to prepare antimonial chelates from Ⅱ as well as from propylenediaminetetraacetic acid (Ⅲ). The antimonial chelate was readily formed on the treatment of the trisodium salt of Ⅲ with antimony trichloride,or on the treatment of Ⅲ with antimonial catechol or freshly precipitated antimonous acid,and the last method was the most convenient one.Ethylene- diaminetetraacetic or propylenediaminetetraacetic acid and potassium antimonyltartrate were dissolved together in water,and hydrochloric acid was then introduced to decompose the latter compound.The newly formed antimonous acid was taken up by ethylenediaminete- traacetic acid or propylenediaminetetraacetic acid present in the solution,and the chelate was readily formed.Several water-soluble salts were prepared on neutralization of the chelate with various alkalis.The corresponding chelating compound of cyclohexane-1,2- diaminetetraacetic acid was similarly prepared. Both N-(β-hydroxyethyl)-ethylenediaminetriacetic acid and N-benzylethylenediamine- triacetic acid gave the corresponding antimonial chelates on treatment with antimonous acid, but such chelates are less stable than those prepared from Ⅱ or Ⅲ.Attempts to prepare some water-soluble salts were not successful,because the chelates were decomposed on addi- tion of one mole of alkali.Lengthening of the carbon chain between the two nitrogen atoms of ethylenediaminetetraacetic acid weakens its chelating power,and antimonial com- plexes could not be obtained under similar conditions from tetramethylenediaminetetraacetic acid (Ib),3-thiapentane-1,5-diaminetetraacetic acid (Ⅵ) and p-phenylenediaminetetra- acetic acid (Ⅶ). Either ammoniatriacetic acid (Ⅷ) or β-hydroxyethylaminediacetic acid (Ⅹ),on treatment with antimonous acid or butyl antimonite,gave the corresponding antimonial chelates.In such complex salts an antimonial atom combined with two moles of chelating agents.These chelates are less stable than those from Ⅱ or Ⅲ.β-Carboxyethylamine- diacetic acid (Ⅸ),a higher homologue of Ⅷ,however,failed to chelate with antimony under similar conditions.Antimonial chelates could not be afforded by a series of alkyl o aralkyl aminediacetic acid (XIa—h) as well. Many of the complexones employed in the present work are known compounds.The preparation of propylenediaminetetraacetic acid was only briefly noted in a patent.We tried to synthesize it by the carboxymethylation of propylenediamine according to Smith's general procedure,but Ⅲ was obtained only in a yield of 27%.A modified method for carboxymethylation was then applied and sodium cyanide and formalin were in- troduced in several small portions into an aqueous solution of propylenediamine and sodium hydroxide.Propylenediaminetetraacetic acid was afforded in 58.5% on acidification of the reaction mixture.N-(β-hydroxyethyl)-ethylenediaminetriacetic acid,the preparation of which has not been recorded in literature,was similarly prepared.Since the antimonial chelate is only sparingly soluble in water,the complexon was more easily isolated from the reaction mixture in the form of the antimonial compound. Preliminary pharmacological tests revealed that the antimonial chelates of Ⅲ,Ⅷ and Ⅹ were as active as tartar emetic against Schistosomiasis japonica in white mice.

The homogeneous gas-phase decomposition kinetics of methylsilane and methylsilane-d3 have been investigated by the comparative-rate-single-pulse shock-tube technique at total pressures of 4700 torr in the 1125–1250 K temperature range. Three primary processes occur: CH3SiH3 CH3SiH + H2 (1), CH3SiH3 CH4 + SiH2 (2), and CH3SiH3 CH2 = SiH2 + H2 (3). The high-pressure rate constants for the primary processes in CH3SiH3 obtained by RRKM calculations are log (k1 + k3) (s−1) = 15.2 - 64,780 Cal/θ and log k2 (s−) = 14.50 - 67,600 2800 Cal/θ. For CH3SiD3 these same rate constants are log k1 (s−) = 14.99 - 64,700 cal/θ log k2 (s−) = 14.68 – 66,700 2000 cal/θ, and log k3 (s−) = 14.3 ‒ 64,700 cal/θ.


Research background: Digital marketing has changed the nature of company-to-customer communication. With rising information overload and reduced decision-making time, touchpoints have gained additional importance by yielding customer loyalty. Yet, the existing digital marketing tools have failed to keep pace with these trends. Companies are lacking a simple framework that focuses on a digital marketing strategy built around touchpoints and customer loyalty. This is especially relevant for B2B companies, which due to their specifics are more dependent on customers and less flexible in adapting of new digital trends.
Purpose of the article: A B2B business strategy tailored to digital trends demands a re-evaluation of prior understanding of a product portfolio, a company?s internal and external environment. The purpose of the article is to present a framework that helps to undertake the necessary changes and enables the connections with industry.
Methods: The suggested model has been drawn from the literature review and extended based on the findings of a multiple case study of Austrian Heating, Ventilation and Air Conditioning (HVAC) industry companies. The fieldwork was conducted in early 2017.  Findings & Value added: Aspiring to follow trends in digital marketing and to help B2B companies to adapt their strategy to ongoing changes in company-to-customer communication, a new framework has been developed. The framework aims to increase customer loyalty and focuses on channels/touchpoints, assets, skills, audience and customer journey. The model could be beneficial for Chief Marketing Officers (CMO) and other C-levels by offering a simple and reliable tool for improving a company's position in the digital marketplace. Moreover, it enables continuous adjustment of an already existing business strategy.

With the rapid development of wireless communication, the channel transmission is close to the Shannon–Hartley theorem, so the birth of new technologies is urgently needed. At the same time, the discovery and development of orbital angular momentum (OAM) provides new ideas for wireless communications. Due to the mutual orthogonality of OAM wave modes, spatial multiplexing becomes possible, beams of the same frequency with OAM can travel simultaneously, and the channel capacity efficiency can be greatly improved.


Diagnostic methods for two major cables, OF and XLPE cables, are presented. As a new diagnostic method for the OF cable insulation, an analysis of the insulation oil sampled from the splices or the end sealing box is proposed. As for diagnostic methods for the XLPE cable insulation, several methods are described to detect water tree deterioration, which is the only major problem with XLPE cables. These methods are classified into off-line and live-line tests. Especially, newly proposed diagnostic methods are discussed, which can be applied to live-line XLPE cables. These are a measuring method of dc current component in ac charging current of cables containing water trees, a method to measure insulation resistance, and a method of detecting electrical tree deterioration in XLPE calbe insulat ion on site.


Abstract A simple three‐pitcher (locally known as '3‐kalshi') filtration assembly made entirely from readily available local materials is tested for its efficacy in removing arsenic from the groundwater of Bangladesh. In a 3‐ kalshi assembly, the first kalshi has iron chips and coarse sand, the second kalshi has wood charcoal and fine sand, and the third kalshi is the collector for filtered water. About 240 L of arsenic contaminated groundwater and groundwater spiked with high concentrations of both As(III) and As(V) were filtered. Analytical measurements were performed by using anodic stripping voltammetry (ASV) for trace level As(III) and As(total) and redox potential. Atomic absorption spectrometry with graphite furnace and Zeeman background correction (AASGF‐Z) and inductively coupled plasma atomic emission spectrometry (ICPAES) were used to validate measurements of arsenic and measure 24 other metals before and after filtration. Total Fe, ionic conductivity, Eh, pH, temperature and flow rates were measured at various stages of the filtration process. It has been shown that more toxic As(III) can be removed from 800 ppb to below the detection limit of 2 ppb. The As(total) can be removed to a concentration below 10 ppb for most samples even at the highest input concentration of 1100 ppb As(total). The dissolved iron concentration decreased from an average 6000 ppb to 200 ppb. Calculations based on compound formation and arsenic adsorption on hydrous ferric oxide show that, with a constant input of dissolved iron the arsenic removal capacity increases linearly with each filtration. Although the role of metallic iron was difficult to quantitate, it provided excess soluble iron in the filtering media of the second kalshi. The wood charcoal was used to remove any organic impurities that may be present in groundwater. The redox potential change shows speciation of iron in agreement with literature data. The decrease in conductivity by 35% of the original value indicates substantial removal of dissolved ions. This is also supported by ICPAES measurement. The filtered water remained crystal clear for months and free from most toxic metal ions. The daily capacity of the 3‐kalshi system varies from 42–148 L/day. The final water quality meets and exceeds the guideline values suggested by USEPA, World Health Organization and Bangladesh. We suggest the use of this simple setup to make potable water.


Soil erosion is one of the thorniest issues which has brought severe environmental problems such as degradation of water quality and soil productivity. Topographic factor, as known as slope length and steepness factor (LS) plays a vital role in soil erosion model, it is multiplied with rainfall erosivity (R), ground cover (C), soil erodibility (K) and soil conservation practices factor (P) to modelling soil loss via Revised Universal Soil Loss Equation (RUSLE). In this research, different resolution of elevation model products were used to calculate the LS factor of soil loss, and also compare with each other to access and determine the most appropriate interval to predict soil loss rate in Warrumbungle National Park (WNP). LS factor was calculated via the Digital Elevation Model (DEM) at 30m from Shuttle Radar Topography Mission (SRTM) and High Resolution Light Detection and Ranging (LiDAR) at 1m, 5m and 10m. Twelve soil sites were selected to collect field-based data, which would compare with the soil loss modelling results. GIS technique was applied to model and geo-visualize the LS factor map. Meanwhile, daily soil loss ratio was predicted from LS factor along with rainfall erosivity, groundcover, soil structure and composition.


The invention relates to a method for the early detection of vortex ring stage in a helicopter, comprising the steps of: - determining of flight control signals to the flight control with respect to the vertical axis of motion of the helicopter, and detecting any resulting movement in the vertical axis of motion of the helicopter and - early detection of vortex ring stage of the helicopter in response to a correlation between the flight control signals and the vertical movements in the vertical axis of movement.


The Sokoto Caliphate, which was based on Islamic law, depended considerably on widespread systematic slavery in political, economic, and social spheres. According to Islamic law, it is only permitted, in principle, to enslave non-Muslims or unbelievers, and ʿUthmān b. Fūdī, the founder of the Caliphate, labeled his principal enemies (i.e. the rulers of the Hausa states and Bornu and their followers) as apostate unbelievers. However, Muslim jurists historically presented conflicting views regarding the permissibility of enslaving apostates. Faced with this legal disagreement, ʿUthmān, referring to numerous preceding scholars, argued that it was permissible to choose any one of several juristic views regarding a legal issue on which scholars disagreed. By the employment of this "free choice theory", he justified the enslavement of those whom he labeled as apostates and consequently authorized the enslavement of all kinds of people whom he had categorized as unbelievers living in and around Hausaland.


The dormitory is a multiple functional site for college students' leisure,usually study,night of rest,which is an important part of university life;the same time,the dormitory environment management is one of the important indexes for harmonious dormitory.Therefore,we should be targeted to guide university freshmen learn to tidy up dormitory,creating good dormitory environment.


Background: The restoration of an endodontically treated fractured tooth has been a challenge for restorative dentists for decades. The performance of fiber posts when used in conjunction with direct composite resin restorations have been largely unreported. This study was conducted with the aim of evaluating the survival rate of endodontically treated teeth restored with adhesive bonded fiber reinforced resin posts and direct composite core with additional crown coverage.

The program of performing a fast and automatic analysis of gamma ray spectra obtained by a Multi-Channel Analyzer (MCA) is developed for the surveillance of the nuclear fuel integrity. The integrity of the nuclear fuel is confirmed by the measurement of the radiation level of the reactor coolant through the real time monitoring and the periodic sampling analysis. In Yonggwang nuclear power plane 3 and 4, the Process Radiation Monitoring System (PRMS), which is a real time monitoring system, provides a measure of the fuel integrity. Currently, its spectrometer channel can identify only one radionuclide at a time since the signal processing unit of the spectrometer channel is a Single Channel Analyzer (SCA). To improve the PRMS, it is necessary to substitute the MCA for the SCA The program is operated in a real time mode and an on-demand mode, and automatically performed for all procedures. The test results by using the National Bureau of Standards (NBS) mixed standard source are in good agreement with those from Canberra System 100 which is a commercial MCA Consequently, the developed program seems to be employed for automatic monitoring of gamma rays in nuclear power plants.


Four chinchillas were exposed to 4 kHz CF octave band of noise at 86 dB for five days. After a recovery period of approximately six months, behavioral audiograms were obtained and auditory nerve fiber activity was recorded. The animals were sacrificed and the cochleas embedded in Araldite resin to obtain surface preparations and 1μ sections of the Organ of Corti. Permanent threshold shifts ranged from 5 to 20 dB between 4 and 8 kHz. VIII nerve recordings showed single fiber thresholds were elevated up to 70 dB between 4 and 14 kHz, while higher and lower CF fibers were essentially normal. Spontaneous activity in some of the animals was equal to or greater than normal. Cochleagrams all showed narrow lesions of inner and/or outer hair cells over approximately a 1‐mm distance. A comparison of the three realms of data revealed the following: (1) The greatest loss in sensitivity from the noise exposure was seen in the single nerve fiber thresholds while the smallest change was seen in the behavioral threshold ...


The relation of the morphology of grains in 430 stainless steel with microstructural parameters,such as grain nucleation density,Gaussian decomposition parameters and Gibbs-Thomson coefficient,was studied based on the CAFE model. The effects of casting conditions,such as superheat and cooling intensity,on the solidification microstructure were also analyzed in this paper. It is found that the grain size and the columnar to equiaxed transition( CET) are both affected by maximum bulk nucleation undercooling and maximum nucleation density. As the Gaussian decomposition parameters and Gibbs-Thomson coefficient increase in an appropriate range,the primary dendrite arm space decreases,but the central equiaxed area increases. Besides,the central equiaxed area decreases with increasing superheat and cooling intensity,while the primary dendrite arm space shows no obvious change.


As survival rates increase, growing numbers of childhood acute lymphoblastic leukemia (ALL) survivors are at risk for somatic and psychosocial late effects. Adolescent and young adult (AYA) survivors represent a distinct and vulnerable group. This study aimed to explore how AYA survivors of childhood ALL experience everyday life after cancer while adjusting to the potential impact of prior disease and treatment.


The investigation of interrelation between attaching organisms and corrosion rate on the mild steel test plate was conducted. The test plates were exposed for 215 days at 1 to 20m depth in Suruga Bay, Sizuoka, Japan. The corrosion rates were revealed to decrease with increasing of attaching organisms and to increase with reducing of them. The green mussles Perna viridis were simultaneously obverved in scattered among on the shell surface of barnacles which already settled and covered over the steel test plates at 1 to 5m depth. The time of attaching of these green mussels in Suruga Bay was estimated to be before the end of November based on the comparative observations on the wet weight and shell size of individuals collected at Tokyo Bay in the same year.


Dr. Hamburger's letter raises several interesting points. Our statement that an IgE level of 200 IU/ml is "normal" is based on several studies"1-3 using a standardized radioimmunosorbant kit (Phadebas IgE test). These studies indicate that IgE levels in normal, "nonatopic," subjects can be as high as 700 IU/ml with the mean in these populations near 200 IU/ ml.
 Dr. Hamburger questions the validity of concluding that our patient was a nonatopic individual. Atopy, as first used by Coca and Cooke in 1923,4 referred to individuals with a hereditary background and personal history of hay fever or asthma.


Despite the fact that the optimal design for nonlinear model depends on the unknown quantity of parameter to estimate basically, its popularity is growing in bio and engineering statistics area since all those models in the area are virtually nonlinear. In this paper we have dealt with the case when the researcher has multiple objectives in experimentation, decision among the competing models, protection against the departure from the assumed model, and the conflicting interests among design criteria. To tackle these issues we attempted several new approaches which are taking advantage of the easiness of constrained optimal design. Several nonlinear models were tested.


The Homeric talent, a quantity of unworked gold, has attracted very little scholarly comment. Yet it is a conspicuous enough feature of the Homeric economy: when Agamemnon lists the gifts with which he hopes to win over Achilles, he includes ten talents of gold (khrusou talanta) in the first line of his plutocratic catalogue. The same sum also features among the gifts Achilles receives from Priam. In what follows, I argue that the talent occupies an anomalous position within the system of Homeric gift exchange, and that this anomaly has interesting implications both within and beyond the Homeric text. The essence of the Homeric economy is that wealth follows or is an expression of personal worth (arete, time) and that all properly heroic transactions involving material things are directed towards intangible, honorific ends, rather than towards material gain. It is what anthropologists have called an 'embedded' economic system, in contrast to the 'disembedded' systems of modern capitalism, in which money has a life of its own and exchange may cut across or even break down existing social structures, rather than being circumscribed by them. In the Homeric poems all valued items derive their value from the uses to which they are put by the heroic aristocracy. Since their way of life is dedicated at all levels to the pursuit of personal time, all the property with which Homeric narrative is concerned is valued according to its perceived capacity to express that time? Value in the Homeric economy, therefore, is related to utility, but not the utility of subsistence. The system is coherent, even complete, but Homer's concentration on the struggles of aristocratic heroes means that certain economic phenomena which external evidence and theory tell us should be present even in an embedded economy are either not represented in the Homeric text, or appear there in a marginalised or distorted form. So, for instance, trade of the sort which archaeology has shown was that in which Homer's contemporaries engaged, and the conversion of agricultural surplus into prestige items (enabling social mobility) are largely absent from the poems.

Daily variations in the melatonin concentration in the blood, pineal organ, and retina of the brook trout, Salvelinus fontinalis, were investigated in July under constant photoperiod (16 h L: 8 h D) and temperature (12 °C). Diel variations in melatonin levels in the blood and pineal organ showed similar patterns, with higher values during the night, whereas melatonin concentrations in the retina increased slightly in the first half of the light period. Light exposure of 1 h duration at mid-dark decreased melatonin levels in the blood and pineal organ in an intensity-dependent manner, whereas retinal melatonin levels increased with increasing light intensities. The minimum light intensity causing significant effects on the melatonin concentrations was 2 lx for the serum and 20 lx for the pineal organ and the retina. The parallelism between pineal and circulating melatonin patterns suggests that the lateral eyes of the trout have no significant endocrine function as far as the melatonin rhythm in the blood ...


Water resource projects are often jointly carried out by a number of communities and agencies. Participation in a joint project depends on how costs are allocated among the participants and how cost shares compare with the cost of independent projects. Cooperative N-person game theory offers approaches which yield cost allocations that satisfy rationality conditions favoring participation. A new solution concept, the normalized nucleolus, is discussed and applied to a water reuse project in southern California. Results obtained with the normalized nucleolus are compared with those derived with more traditional solution concepts, namely, the nucleolus and the Shapley value.


The recent increase in suicides highlights the urgent need for better treatment of severe depression. ECT is an intervention proven to reduce suicidality, yet it is underused because of the associated stigma.

Recently,a novel flame retardant ——expandable graphite (EG) has appeared in literatures.The comparisions were made between the flame retardant behavior of EG and that of some halogen-free flame retardants (HFFR) in rigid polyurethane foams (RPUF).And the synergistic effects of EG with some HFFR in RPUF were studied by the approach of limited oxygen index (LOI).The results show that EG is the best flame retardant in RPUF,and the synergistic effects of EG with ammonium polyphosphate (APP) and triethylphosphate (TEP) in RPUF are the best.


In a programmed temperature retention index (PTRI) database, there exists a characteristic parameter rt0/β that can be calculated if the experimental parameters are clearly given. This characteristic parameter can be used to flexibly reproduce the original PTRI data under chromatographic conditions different from those originally given. As this characteristic parameter is not explicitly given, it is suggested to name this parameter as the implicit characteristic parameter (TCP) of a PTRI database. The ICP in White's PTRI database was easily found and used satisfactorily to reproduce PTRI of some test compounds using either a Hewlett-Packard ultra-performance OV-1 column or a self-coated OV-1 column. The reproduction of PTRI could not be realized on columns of different materials. The fact that several PTRI databases measured on glass capillary columns could not satisfactorily be reproduced on fused silica column is explained.


This paper describes the processes followed for the creation of a fire safety application for iPhone/iPad devices, which, for educational reasons, has produced R&D and is applicable to professional practice, and is based on two, apparently unconnected points: 1. University teaching, research and the professional practice of architecture should not be unconnected activities, but the complex reality of the world of construction means that they are seen as separate. / 2. It is obvious that many technological tools such as PC tablets, smartphones... are being used by the general public in their everyday lives. With these precedents, the aim of the project was to create a software program so that a student, lecturer or professional architect could, at any time or any place, use the tool to calculate the main fire safety parameters for a residential building (number of sectors, occupation, structure resistance and dimensions of the evacuation routes) obtaining a result which, beyond regional or national regulations, assesses the appropriateness of the proposal. Thus, based on the Spanish norms, and with reference to the Performance Based Design so as to be applicable to any project, we have a simple software program which returns the mentioned parameters with the input of only six pieces of data on the building.


The ratio of ground-state densities R Q E N( 1 C0)/N(C 1 0) has been used to infer physical and chemical conditions in giant molecular clouds (Wannier et al. 1976) and dark clouds (Mahoney et al. 1976; Langer et al. 1979). In dark clouds R Q is found to vary from values near the terres trial ratio [ l C][ 1 0]/[ 1 C][ 1 0] ̂ 5 at positions of high extinction to values ^20 at positions of low extinction. In this paper we present highresolution J = 1 -> 0 spectra of CO, 1 3 C 0 , and C 1 8 0 at positions of high extinction in TMC-2, L134, and L134N. The C 1 0 lines have non-Gaussian wings and are ^ half as wide as the 1 C0 lines. We find that R Q must vary across the line, from a minimum of R 0 ^ 4 at the peak of the C 1 8 0 line to a maximum of R Q ^ 10 in the wings, unless the 1 C0 line has peak opacity £5. The variation of R Q with position and with velocity is consistent with models of clouds which have a dense core with low velocity-dispersion and low fractionation, and a rarefied envelope with high velocity-dispersion and high fractionation.


Here, we report a combined study of transport and thermodynamic measurements on the layered pnictide material SrAg4As2. Upon cooling, a drop in electrical and Hall resistivity, a jump in heat capacity, and an increase in susceptibility and magnetoresistance are observed around 110 K. All suggest nonmagnetic phase transitions emerge at around 110 K, likely associated with structural distortions. In sharp contrast with the first-principles calculations based on the crystal structure at room temperature, quantum oscillations reveal small Fermi pockets with light effective masses, suggesting significant change in the Fermi surface topology caused by the lowtemperature structural distortion. No superconductivity emerges in SrAg4As2 down to 2 K under pressures up to 2.13 GPa; instead, the low-temperature structural distortion moves up linearly to high temperature at a rate of ≈13 K/GPa above 0.89 GPa.


The possibility of the continuity of sale growth of a specialized tourist product from the small country in transition on the global tourist market justifies the means invested in the development of the strategic model of positioning of a new tourist product. In terms of that aim it is necessary to give meaning to a viable strategic model of product management by tactical platform. Globalization and communication standards in tourism present a particular challenge for specialized tourist product. The possibility of continuity of growth in sale of original and competitive specialized tourist products account for the efforts and means exerted in making a strategic model of the product's positioning in the aimed niche on the global tourist market. What are the key variables to which a specialized tourist product from a country in transition needs to pay attention in order to position itself in an acceptable niche of the global tourist market? Which strategic model of positioning to apply in a particular case in lighthouse tourism on the Adriatic Sea? The problem of commercialization of the new specialized tourist product, such lighthouses tourism, in the practice has also national administrative barriers, imposed by governmental legal rules. These buildings are national property and an important part of national safety in navigation's system. Lighthouse tourism is a promotion of creation national brand, so as a promotion of the Croatia. Inappropriateness of economic measures to recessionary trends on the global tourist market is often a rule, not an exception. The possibility of the continuity of sale growth of a specialized tourist product from the small country in transition on the global tourist market justifies the means invested in the development of the strategic model of positioning. In Stone Light project (Lighthouse tourism) the way out was through the development of the following key strategically tactical model: • Branding system for creating a recognizable global label of a specialized tourist product ; • E-marketing system for the continued adequate communication with the global tourist market ; • E-commerce system for the sales management on the global tourist market ; • Logistical system for the sea transfer ; • Organization system for solving possible problems according to the standards of the global tourist market. The expected scientific contribution of the works consists in accepting or rejecting the basic hypothesis: Strategically model of exclusive sub segmentation of the new tourist product of a small country in transition on the global tourist market is effectively realizable on the tactical platform: Branding/ E-marketing/E-commerce/ Logistics/ Organization.


Several flatness-based current controllers for three-phase three-wire boost rectifiers are compared. For this purpose, the flatness of a rectifier model is shown, and a trajectory planning algorithm that nominally achieves voltage regulation in finite time is given. The main focus lies on the inner loop current controllers. On one hand, linearization-based controllers using exact feedback linearization, exact feedforward linearization, and input-output linearization are discussed. On the other hand, two passivity-based approaches are compared. The first one is the energy shaping and damping injection method, and the other one uses exact tracking error dynamics passive output feedback. Furthermore, a reduced-order load observer is given, and a method that allows the prevention of invalid switching patterns is presented. The presented control algorithms are tested by simulations on a switched model.


OBJECTIVE
To explore the use of dental operating microscope with ultrasonic instruments in root canal retreatment.

METHODS
164 root canals in 124 teeth of 111 patients who need root canal retreatment were treated under dental operating microscope (DOM) with ultrasonic instruments, then the success rates were calculated.

RESULTS
Both 136 root canals with a success rate of 82.93% from 164 root canals and 103 teeth with a success rate of 83.06% from 124 teeth were managed successfully. The each category of the retreated teeth was 85.29% for calcified canals, 83.33% for canal subjected to resinifying therapy, 86.67% for misunderstood root canals, 100% for canals blocked by post, and 66.67% for both root canals blocked by instrument fragments and ledged.

CONCLUSION
The use of microscope and ultrasonic instruments was proved to be an effective way in the root canal retreatment.


This paper describes the chronological changes of the unit system adopted in section PW-43, Rules for Construction of Power Boilers, of ASME I in its seven editions issued from 1995 to 2013, followed by analyses on causes of confusions ever occurred in calculations, giving methods to convert the units in the imperial system into those expressed in the metric system.


Live projects and complex interdisciplinary collaborations enrich learners' experiences of their courses and their own creative practice. Opportunities for collaborative working that lie outside the curriculum of a course are to be welcomed and sought proactively. That said, collaborative projects bring with them complex logistical challenges for busy course teams and their cohorts. How to balance invaluable opportunities for extra-curricular experience and collaborative working with the exigencies of delivering existing modules?
When the students, alumni and staff of BA (Hons) CG Arts & Animation were challenged, as part of an EU Interreg/ACT partnership project, to create an original sixteen minute animation to be synched with a live performance of classical music, the course team looked to its network of course blogs and 'community of practice' as the means by which the collaboration might be facilitated. The successful execution of the brief was achieved by the community demonstrating the characteristics of a community of practice as set out by Wenger (c.2006). The shared domain of interest provided a fertile environment within which to cultivate ideas, while the strong sense of community and skills of the practitioners enabled the rapid and distributed production of a complex visual composition.

This presentation explains the creative process that led to the realisation of La Creation du Monde, illustrating the power of a creative community of practice.


In Modern Communication Systems the patch antennas are the most important components to create a communication link. The demand for high data rate and efficiency has expanded as wireless applications, services, and technology have advanced. Wireless communications frequently employ the patch antenna. An E-band microstrip antenna with line feeding and square shaped loaded on the radiating patch is depicted in this work's analysis. The simplest structure of the proposed microstrip antenna is $5.6\times 7\times 0.4\ \text{mm}^{2}$. The patch of an antenna is printed on the substrate on FR4 material. The E-band of the antenna operates in the frequency and covers the range from 60 GHz to 110 GHz. The obtained return loss of an antenna is −44.36 dB and a gain of an antenna is 8.78 dB at the operating frequency of 88GHz. The voltage wave standing ratio (VSWR) of an antenna is 0.1369dB. The majority bandwidth of an antenna is 19.125GHz at the operating frequency of an E-band. This project presents the design of a compact re-configurable E band slotted patch antenna system by its parameters like low return loss, low VSWR, directivity, high gain and bandwidth yet to be achieve. This antenna is specifically suited for backhaul applications for 5G mobile. ANSYS high frequency simulation software (HFSS) was used to simulate this microstrip patch antenna. As a result, the suggested antenna might be able to satisfy all the criteria needed for 5G mobile applications.


J . W. S. Cassels [1] has shown that if a stellar set S intersects all the subgroups of index ^ m in an abelian group without elements of finite order than \S\^m. Our result is an improvement for m = p. Let g. c. d. (au idk) denote the greatest common divisor of a19 " ,ak. Let Va denote the Cartesian product of n ^ 1 copies of Zp<*, the residue class ring modulo p . Let ΛQ denote the free abelian group of rank n. An %-tuple (in Λo or in Va) is said to be p-primitive if p does not divide at least one coefficient of the %-tuple. An integer x is said to be p-prime if g.c.d. (p, x) — 1. Let F * denote the set


As the world reaches the "era of migration", how should the museums of a country like Singapore, that focus greatly on its multicultural/ethnic heritage, face issues of migration? This paper takes the National Museum of Singapore (History Gallery) and the Chinatown Heritage Centre as case studies, conducts interviews and analyzes exhibitions to discern the transition, history and memory of the early Chinese migrant laborers; and how the laborers' images further depict national history. This study found that both museums consciously attempted to cross the border that national awareness laid for exhibiting history, by integrating migrant laborer into national history, strengthening today's multivariate society as results of migration. Citing from film/theater elements, the early Chinese migrant laborers are provided with a voice equal to the "museum voice", allowing them to dramatically went from the other to the self. However, the multi-voice experience seemed to be co-weaving a "single narrative, such as the continuation of colonial race system to discipline, govern and strengthen nation-ethnic stability. Further, the museums use the laborers' images to shape a new national identity; images of diligence, loyalty, and national devotion projected the value and expectation of modern Singapore society. In addition, the perspectives of the 'hui-kuans' demonstrated a fracture between the nation- constructed and local culture identity, as the latter contravenes with national discourse; the delineation of Singaporean identity becomes clear though the process of losing, finding and embedding one's roots within the complicated self-other relationship. On displaying migration history under a multicultural and multi-ethnic society, NMS can direct the public to ponder on the construction of borders, to realize that a multicultural society is built on the encounter and intermingle of self and other, and numerous diaspora, boarder-crossing, rooting and dislocating. CHC, as the significance of Chinatown lies in its locality and the historical memory etched to its landscape and people, has great potential in place-making and localizing the memories and meaning of early Chinese migrants. Perhaps though this kind of discourse, mobile borders can be possible.


High-accuracy metrology is vitally important in manufacturing ultra-high-quality free-form mirrors designed to manipulate X-ray light with nanometer-scale wavelengths. However, surface topography measurements are instrument dependent, and without the knowledge of how the instrument performs under the practical usage conditions, the measured data contain some degree of uncertainty. Binary Pseudo Random Array (BPRA) "white noise" artifact are effective and useful for characterizing the Instrument Transfer Function (ITF) of surface topography metrology tools and wavefront measurement instrument. BPRA artifact contains features with all spatial frequencies in the instrument bandpass with equal weight. As a result, power spectral density of the patterns has a deterministic white-noise-like character that allows direct determination of the ITF with uniform sensitivity over the entire spatial frequency range. The application examples include electron microscopes, x-ray microscopes, interferometric microscopes, and large field-of-view Fizeau Interferometers. Furthermore, we will introduce the application of BPRA method to characterizing the ITF of Cylindrical Wavefront Interferometry (CWI), by developing the BPRA artifact which matches the radius of curvature of the cylindrical wavefront. The data acquisition and analysis procedures for different applications of the ITF calibration technique developed are also discussed.


Two recent papers on managing new product diffusion decisions under production constraints reach somewhat contradictory conclusions. Ho et al. (Ho, T.-H., S. Savin, C. Terwiesch. 2002. Managing demand and sales dynamics in new product diffusion under supply constraint. Management Sci.48(2) 187--206) show that it is never optimal to refuse to satisfy any customers when the firm has inventory of the product. On the other hand, in a very similar model, Kumar and Swaminathan (Kumar, S., J. M. Swaminathan. 2003. Diffusion of innovations under supply constraints. Oper. Res.51(6) 866--879) show that production constraints may in fact lead a firm to reject customers' orders even when the firm has the inventory to satisfy them (to slow down new product diffusion). We provide a counterexample to the results of Ho et al. (2002) and show that in their and Kumar and Swaminathan's (2003) models, it may be optimal to deny customers a product in inventory. We provide a generalization of both models that includes the ability to dynamically price the product (and also allows capacity and production costs to vary over time). We show that the unintuitive but optimal behavior of denying customers products that are in inventory disappears when the firm can dynamically set prices.

Abstract. In this paper, the advantages of using the artificial grass composites instead of the natural grass are going to be discussed. FIFA sets down the rules of the game which cover the ball's weight, material, circumference, sphericity, pressure and also, the use of the artificial grass composites. Artificial grass composites were introduced as an alternative to natural turf in an attempt to overcome some issues such as shortage of water, increased participation in sports and high operational and maintenance costs. Hence, it is important to know the regulations and the quality controls of the ball that can be used in the game. This can be done by developing a theoretical approach describing the behavior of the artificial grass, developing the parameters recommendation catalog and designing the football end-use artificial grass according to FIFA regulations.


A principle prototype of 6-DOF (six degree of freedom) wire-driven parallel manipulator--WDPSS-8 (WDPSS: Wire-Driven Parallel Suspension System, 8: eight wires) has been designed and built in this paper. The kinematics model and dynamics model have been established in moving and fixed coordinate system set in the model and the manipulator respectively. The trajectory of the aircraft model along a spiral curve has been marked out for analysis. Since the solution of dynamics equation is multiple for a given motion of the model because of superfluous constraint, optimization method has been employed to search a reasonable wire tension system. The simulation including the kinematics and dynamics analysis has been carried out in the environment of MATLAB. The length and tension of the wires driving the model have been presented. The results will help to control the model's movement and calculate the aerodynamics of vehicle model in wind tunnel tests. The research will lay foundation for WDPSS used in the actual wind tunnel tests. And it proves WDPSS-8 may be used as the support system of vehicle model in the wind tunnel test.


The crossing number of a graph G is the smallest number of edge crossings in any drawing of G into the plane. Recently, the first branch-and-cut approach for solving the crossing number problem has been presented in Buchheim et al. [2005]. Its major drawback was the huge number of variables out of which only very few were actually used in the optimal solution. This restricted the algorithm to rather small graphs with low crossing number.
 In this article, we discuss two column generation schemes; the first is based on traditional algebraic pricing, and the second uses combinatorial arguments to decide whether and which variables need to be added. The main focus of this article is the experimental comparison between the original approach and these two schemes. In addition, we evaluate the quality achieved by the best-known crossing number heuristic by comparing the new results with the results of the heuristic.


Complex network theory is applied to study the inherent vulnerability of power transmission grid under cascading failures. It introduces the complex analysis model and some basic conceptions of network characteristic parameters and its algorithm to calculating network efficiency, then it applies proposed algorithm to analyze the complex characteristics of power grid while occurring the cascading failures triggered by link failures, and qualitatively analyzes the resistible ability of power grid in case change of topological structure. Taking advantage of qualitative simulating results, we may determine the vulnerable regions which affect the performance of power transmission network.

A type B band of the asymmetric rotor molecule methane d2 was observed in the 5880-6136 cm-1 region. The band was assigned as 2ν3b, the first overtone of the ν3b band observed by Wilmshurst and Bernstein. The analysis of the band utilized the Kivelson and Wilson approximation for centrifugal distortion corrections to the energy levels. Assignments were made for transitions having values of J = 0 to J = 12. A tracing of the observed spectrum of the band has been given along with the predicted spectrum of the band. Values were obtained for the rotational constants: A−or+ = 4301, B−or+ = 3505, C−or+ = 3054 cm-1 for the ground vibrational state and Aprime = 4247, Bprime = 3462, Cprime = 3025 cm-1 for the upper vibrational state. The band centre was located at 5999126 cm-1. Centrifugal distortion constants were calculated for the ground vibrational state and estimates were made of the upper-state centrifugal distortion constants.

[1] A long deformation record (∼16.5 ka) showing nonsteady earthquake recurrence is established for the Aksu thrust (Tianshan, China) on the basis of cosmogenic 10Be dating of faulted surfaces. Topographic leveling across the Aksu fault scarp indicates up to ∼10 m uplift across a moraine abandoned ∼16.5 ka and similar uplift of ∼6 m across two inset surfaces yielding ages of ∼12.5 and ∼5 ka. Successively smaller uplifts of terraces younger than 5 ka indicate that three or more major earthquakes occurred during this period. These data show that the Aksu thrust fault was quiet for at least 7500 years and active in the last ∼5000 years and probably in the interval 16.5–12.5 ka. The seismic cycle along the Aksu thrust fault over the last ∼16,500 years was thus strongly irregular showing long quiescence and clustering, which is a challenge for paleoseismology and hazard assessment. This irregularity also makes it more difficult to estimate long-term shortening rates. Nevertheless, we are able to constrain a minimum total shortening rate (>7 mm/yr) across the southern Tianshan front for the last 12,500 years that is about a third of the total geodetic rate for the western Tianshan (∼20 mm/yr).


A simulation algorithm for defining the distribution of eigenvalues of a random symmetric matrix with arbitrary continuous joint probability density function of its entries is presented. The algorithm requires only a uniform random number generator. As a numerical example, the probability that eigenvalues of a certain random symmetric matrix satisfy a given condition is calculated using software implementing the algorithm.


Multi-tenant Software as a Service (SaaS) is the cloud computing delivery model that maximizes resource sharing up to the level of a single application instance servicing many customer organizations (tenants) at once. Due to this scale of delivery, a SaaS offering, once successful, becomes difficult to upgrade and evolve without affecting service continuity and tenant businesses profoundly. However, not all tenants are equal, and to some organizations such disruptions are more costly than to others. To account for such tenant-specific requirements, middleware for upgrading SaaS applications should support tenant-specific enactment of upgrades that allow for a customizable schedule and type of enactment in accordance to the tenant SLA. In this paper, we present our design and implementation of a SaaS middleware that enables run-time adaptation by means of a gradual tenant-by-tenant activation of upgrades. The adaptation mechanism is multi-staged, i.e. supports configuration based on the inputs of the tenant administrator and other stakeholders, and is maximally automated. We have validated the middleware in an OSGi-based prototype implementation and evaluated this prototype, showing negligible performance overhead of the middleware and yet clearly showcasing service continuity improvements in realistic upgrade scenarios.


The electromagnetic scattering problem of a short-pulse plane wave by a perfectly-conducting circular cylinder, buried in a dielectric half-space, is solved by means of a cylindrical-wave approach (CWA). The incident plane wave may have a rather general shape in the time domain. The technique is applicable for arbitrary polarization, for any cylinder size and burial depth, and it gives results both in the nearand in the far-field regions. In this work, an application of the technique to a basic but practical detection problem is presented, showing good results.


Abstract This paper arose from research into a class of 11–year-olds' relationships with poetry. The paper describes how by analysing the children's comments about poetry it became clear that their parents were active in rigorously selecting, censoring and generally controlling the children's reading diet, most markedly with poetry, and that patterns began to emerge of how they went about this task. In an analysis drawing on Ball and Vincent's (2005) work it became clear that processes of social reproduction were at work.


ABSTRACT The COVID- 19 pandemic changed familiar working practices overnight; Routine face to face meetings could not be held, accordingly, businesses were forced to replace routine meetings by digital technology to engage socially dispersed stakeholders in the task of maintaining business continuity. Radical sports cars are a motorsports business that has recently undergone turnaround and is beginning the transitional journey to recovery. Turnaround is a traumatic process for everyone involved. and generally, demands strong leadership, while on the other hand, the recovery phase requires the engagement of a diverse range of personalities and skills who are expected to form into a team with a shared vision and goals. This paper will report from an insider researcher's perspective including a short description of the business turnaround undertaken that contextualises the unexpected challenges that emerged, and, how adaptive action learning was utilised to augment other mechanisms that were able to continue through the Covid 19 crisis, thus, this work does not explore the meaning or the process of action learning, but rather provide a first-hand "lived experience" of adaptive action learning as applied to Radical sportscars. it is worth nothing here that the problems encountered, largely conform to the "wicked" descriptive.

This study aims to determine "The Effect of Financial Compensation and Non-Financial Compensation on Employee Performance of PT. Jaya Beton Indonesia Medan Branch. " This type of research is causal research (Causal Reaserch) which aims to test the hypothesis. The population in this study were 56 permanent employees. And by using saturated sample techniques, the number of samples used in this study were 56 respondents taken from all employees. Based on the results of the t test, it can be seen that the tcount on the financial compensation variable is 3,845, greater than the t table of 2,006 with a p-value that is sig 0,000 smaller than 0,05. Based on this value, the financial compensation variable has a positive and partially significant effect on the Performance variable. In the non-financial compensation variable, the tcount is 1,535 which is smaller than the table that is 2,006 with a p-value of 0,131 which is greater than 0.05. So the non-financial compensation variable does not have a positive and partially significant effect on employee performance. Based on the F test results, the Fcount value of 8,841 3.16 was obtained with sig 0.001 0.05 indicating Ho was rejected and Ha was received, meaning financial compensation and non-financial compensation had a positive and significant effect simultaneously on employee performance. The R2 value obtained is 0.242. To see the effect of independent variables on the dependent variable by looking at the R square table which shows 0.242. which as much as 24,2% of employee performance is influenced by financial and non-financial compensation and 75,8% is influenced by factors not explained in this study.

In the last decade, there has been a trend rising towards the improvement of the methods for effective contractor evaluation. Governments may have been utilizing these kind of studies during legislation and legal regulations on procurement. To achieve the best value for money, the tender evaluation should consider not only price competitiveness, but also compliance with users' requirements, reliability of performance, capabilities and experience, qualitative superiority, and whole-life costs. Turkish public authorities arise the need for proper contractor selection approach including factors other than price. A contractor selection model is structured to cover non-price attributes together with the bid price. The concern of the model is the public authorities, who want and need to consider the factors other than price during contractor evaluation process of middle-size and semi-complex projects. The model is tested by a hypothetical scenario which evaluates four contractor candidates. The results show that the model provides a guide for the public client to reward experienced, capable and qualified candidate contractors, and to eliminate incompetent, inexperienced, or underfinanced contractors for the success and quality of works. Key words : Procurement, Public Sector, Clients, Contractor Evaluation, Contractor Selection


ABSTRACT In this research, a thorough experimental and numerical study is conducted to investigate a novel application of the ultrasonic Lamb waves which is its capability to detect the coating disbond in a double-layer waveguide (aluminium-adhesive) and a triple-layer waveguide (aluminium-adhesive-coating). The experimental tests are set up and implemented to evaluate how the attenuation of Lamb waves is affected by the adhesive bonding beside the contribution of the coating layer to the behaviour of Lamb waves. In the presence of additive white Gaussian noise (AWGN), a range of important indices including energy index (EI), amplitude index (AI), pulse width index (PWI), and the time of flight index (ToFI) are worked out in association with the disbond length. It is inferred that a) even in the very noisy environment of 0 dB SNR, the Lamb waves are effectively able to identify debonding defects particularly using the EI, giving sensitivity rates 105% and 30% for triple-layer and double-layer, respectively; b) the contribution of adhesive to the absorption of the guided wave energy is 30%, 40%, and 50% in EI, AI, and PWI, respectively, corroborating the value of the features to distinguish the debonding between each layer of bonded structures.


As a result of the years-long conflict in Syria, many Syrians have been forced to move to safer areas near the Syrian-Turkish border in the north. As a result of the deteriorating economic conditions, the displaced people are forced to live in tents in camps that lack the basic needs of human beings. In addition, these camps did not protect the residents from the severe weather conditions in summer and winter. This paper proposes a sustainable economic solution by building special earthen domes that provide independence and social interactions between the residents of the camp. The solution presents different architectural models that are adapted to the needs of the displaced and provide thermal insulation and consider the economic and social aspects by relying on earth in providing the building materials. The displaced may participate in building their own houses in a way that secures decent life.


Particle removal efficiency is studied as a function of several different SC1/megasonics parameters while trying to maintain oxide loss at less than 1 A. It is found that high particle removal efficiency can be maintained down to oxide loss levels of 3 A in a spray acid tool. Below this level of oxide loss particle removal efficiency is greatly reduced for both spray and immersion tools. There is also a dependence on dissolved gas where high and low levels of dissolved gas cause a reduction of particle removal, while an intermediate level, corresponding to about 450 ppb of dissolved oxygen gives optimal particle removal. With tank modifications, megasonics energy can be used to remove particles with an oxide loss of 1 A and without damaging 60nm wide polysilicon lines with an aspect ratio of over 3.0.


Recent phase 2 data showed that the small molecule regorafenib with antiangiogenic properties has promising effectivity in glioblastoma patients at first progression. Following antiangiogenic therapy with bevacizumab, amino acid PET provides valuable additional diagnostic information regarding bevacizumab-related effects on MRI (e.g., pseudoresponse). In contrast, only a little is known about regorafenib. Thus, we evaluated prospectively the value of O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET for the assessment of regorafenib-related treatment effects.

 Twenty-two patients with progressive malignant glioma (median number of relapses, 2; range, 1-4) were included. Up to now, 10 of 22 patients were eligible for data evaluation and underwent regorafenib therapy (median number of cycles, 2; range, 1-5 cycles). FET PET and MRI were performed at baseline and after the second cycle. After the second cycle, MRI was performed every 8 weeks. In case of a suspicious MRI after the second cycle, a FET PET scan was added. MRI changes were evaluated according to the RANO criteria. Maximum tumor-to-brain ratios (TBRmax) were calculated. Pseudoresponse was considered if (i) the follow-up MRI showed an improvement (i.e., at least "partial response" according to RANO criteria) despite subsequent clinical progression, and (ii) an increase of TBRmax>25% occurred. Pseudoresponse was confirmed if (i) the subsequent MRI follow-up showed progression, and/or (ii) the clinical status worsened, or the patient died.

 In 4 of 10 patients, FET PET provided clinically relevant additional information. In two patients, pseudoresponse could be confirmed. Furthermore, in one patient with stable disease according to MRI, increasing TBRmax (+138%) enabled earlier diagnosis of tumor progression (time benefit, 5 weeks). In another patient without signs of MRI response after 2 cycles, decreasing TBRmax (-23%) indicated metabolic response and was associated with a significant clinical improvement.

 FET PET seems to add valuable diagnostic information for regorafenib therapy monitoring.


In ultrasound, second harmonic imaging is usually preferred due to the higher clutter artifacts and speckle noise common in the first harmonic image. Typical ultrasound use either one or the other image, applying corresponding filters for each case. In this work we propose a method based on a joint sparsity model that fuses the first and second harmonic images while performing clutter mitigation and noise reduction. Our approach, Fused Morphological Component Analysis (FMCA), uses two adaptive dictionaries for characterizing the clutter components in each image, and a common dictionary for the tissue representation. Our results indicate that the obtained images contain less clutter artifacts, less speckle noise and as such enjoy of the benefits of both harmonic input images.

Hirota equation is a modified nonlinear Schrödinger (NLS) equation, which takes into account higher order dispersion and delay correction of cubic nonlinearity. The propagation of the waves in the ocean is described, and the optical fiber can be regarded as a more accurate approximation than the NLS equation. Using the algebraic reductions from the Lie algebra [Formula: see text] to its commutative subalgebra [Formula: see text], we construct the general [Formula: see text]-Hirota systems. Considering the potential applications of two-mode nonlinear waves in nonlinear optical fibers, including its Lax pairs, we use the algebraic reductions of the Lie algebra [Formula: see text] to its commutative subalgebra [Formula: see text]. Then, we construct Darboux transformation of the strongly coupled Hirota equation, which implies the new solutions of [Formula: see text] generated from the known solution [Formula: see text]. The new solutions [Formula: see text] furnish soliton solutions and breather solutions of the strongly coupled Hirota equation. Furthermore, using Taylor series expansion of the breather solutions, the rogue waves of the strongly coupled Hirota equation can be given demonstrably. It is obvious that different images can be obtained by choosing different parameters.

moral death, as evidenced in Job's questioning cries about injustice. The Hebrew Bible hints at resurrection and judgement, and the use of the imagery of Ge-Hinnom (Gehenna) became influential in ideas of both punishment and destruction. Yet it is the Book of Enoch which presents the most sophisticated scheme of judgement, separation, and punishment. Here Sheol and Gehenna appear to be identified, and a more systematic vision evolved. Thus the Jewish image developed when it became apparent that present evil laughs in the face of justice. There must be some future restoration. The last part of the book analyses the New Testament and early Christian reflections on the doctrine of hell. In so doing, B. identifies themes of destruction, damnation, concepts of divine sovereignty and mercy, and the defence of eternal punishment as found in Augustine. Differences of opinion may appear concerning B.'s use and interpretation of materials at certain points, but in a work as wide-ranging as this, such quibbles are of relatively little importance. B.'s study is captivating, and should certainly become the standard work on the history of what has become an important image in Western civilization. Whilst helpfully drawing out important strands from the material, B. never attempts forcibly to harmonize all the evidence. This study will be of great interest not only to historians, but also to theologians, sociologists, and psychologists. B.'s breadth and depth of scholarship makes the study of a distasteful and obscure concept become at once alive and enthralling.


The three novel methylene bis[flavonoids] 1–3, the novel 2-flavene 4, the new naturally occurring flavan 5, and the new retro-dihydrochalcone 6 were isolated from dragon's blood of Daemonorops draco, together with seven known compounds. The structures were elucidated by extensive 1D- and 2D-NMR spectroscopic analysis.


Psychiatric diagnostic profiles, drug and personal histories, and social support measures were obtained for a clinic sample of abusers of pentazocine when the drug was withdrawn and re-released by the manufacturer compounded with the opiate antagonist naloxone. Nearly 50% of the sample (N = 99) reported using the new drug during the following 6 to 9 months, despite its reduced abuse potential. Reinterviews revealed that claimed use of pentazocine dropped to half.

Great importance is added to the municipalities that has a high green area index. But this can be an empty and wrong parameter when ignored the environmental quality of these green areas. This work aimed to study and compare the environmental quality of three green areas of Curitiba – Parks: Nascentes do Rio Belém, São Lourenço e João Paulo II (Bosque do Papa) – located in the basin of the Belém river. For this, we analyzed through rapid ecological assessment, floristic aspects, physiognomic-structural and conservation of existing forest remnants in these green areas. In each green area held data collection in five sampling points distributed randomly in the existing forest fragments. Degree of invasion and human disturbance were also observed. It was revealed the initial stage of succession of Nascentes do rio Belém Park and the intermediary stage of succession of the others two parks. The presence of exotic species tended to worsen as the proximity to the city center. The fragmentation of arboreal mass also showed differences in the survey of the species as their diversity and frequency in the area. Possible connections, such as runners also showed influence. We observed the occurrence of 105 species and 54 native plant families, and 22 exotic species, 13 of which are invasive. The São Lourenço Park presented the green area with the highest number of species. Since those areas in the same basin was observed in the landscape around the presence of other forest fragments in connection with the green areas. Opportunity for a better living city-nature.
