I the study of inflammatory lesions of blood vessels, some basic problems have remained unsolved since Rokitansky first described the gross pathologic features of the lesions in 1852 (cited by Zeek1). Widely varying views are held on the classification of this group of disorders in spite of the extensive literature on the subject. The differentiation of polyarteritis nodosa from the vascular lesions designated by Zeek and associates2 as hypersensitivity angiitis has stimulated many of the recent studies. Some authors2"4 clearly distinguish polyarteritis nodosa from hypersensitivity angiitis, while others 5' 6 do not. Nosology of the significant vascular changes found in Wegener's granulomatosis,7 allergic granulomatosis,8 and a variety of less well defined generalized vascular diseases9,10 is also controversial. Experimental data have failed to elucidate clearly the basic mechanisms in this perplexing disease group, and the morphologic examination of material from human beings remains a significant method of study. With these considerations in mind it was believed that a review of the autopsy findings in cases of these disorders would be valuable. From a review of the records of all autopsies performed here between 1942 and 1964, 27 cases of necrotizing angiitis were selected. The series of 27 cases was divided into three types: (l) polyarteritis nodosa, (2) hypersensitivity angiitis, and (3) Wegener's granulomatosis. The term 'necrotizing angiitis' is used to suggest that the fundamental process is vascular and not secondary to disease of other organ systems. We have previously reported the clinical features of this group of cases.11


A problem of the boundary control by the displacement at the point x=0 with the Neumann condition at the point x=l is considered for the process which is described by the telegraph equation with a variable coefficient on the finite interval 0 ≤x ≤1. For the critical time period T=2l a necessary and sufficient condition for the existence of a unique boundary function  μ(t)=u(0, t) which transfers the process from any initial state at t=0 to any terminal state at  t=T is given.


Introduction Intracerebral hemorrhages (ICHs) are a source of significant mortality and morbidity worldwide, and even those who survive the insult have a higher future mortality than the general population.1 Given this, prompt recognition, hematoma volume and location, differentiation from intraventricular hemorrhage (IVH) and the presence of hydrocephalus are known features related to unfavorable outcomes. An artificial intelligence (AI) fully automated detection system is thought to ameliorate ICH detection and measurement, which could potentially improve condition recognition and patient prognosis. Methods A retrospective analysis of non-contrast CTs (NCCTs) from a single center, randomly picked from prospective cohort of acute stroke patients, was done to compare the semi-automated expert-based (OsiriX MD v.9.0.1) ratings versus AI algorithm ratings. NCCTs from 2014 to 2017, for both ICH (presence and volume) and other neuroimaging findings (such as IVH) and non-ICH subjects were analyzed. Same scans were rated by Viz-ICH® v2.0 – an Artificial Intelligence Automated Convolutional Neural Network. Results Preliminary analysis of subjects: 689 NCCTs were evaluated – of those, 537 had ICH and 152 were non-ICH (control group). ICH group findings: mean age 59.3±13.5, bNIHSS 13[4–22], ICH volume of 26.6±36 cc, males 56.4% hypertension 86.2% and presence of IVH 51.7% of them. Intraclass Correlation Coefficient (uncontrolled for IVH): α=96.1% (IC95%=0.900–0.933; p≤0.001) and sensitivity 94.5%. Maximal running time of the algorithm was under 15s. Conclusion The presence and volume of ICHs can be accurately predicted by AI Viz-ICH Algorithm, with good differentiation from IVH and other neuroimaging findings. The software has the potential for appropriate and rapid diagnosis of these patients. Disclosures C. Barreira: None. M. Bouslama: None. J. Ratcliff: None. G. Pradilla: None. H. Rahman: None. A.

Many partial differential equations with rapid spatial or temporal scales have effective descriptions which can be derived by homogenisation or averaging. In this article we deal with examples, where quantitative estimates of the error is possible for higher order homogenisation and averaging. In particular, we provide theorems, which allow homogenisation and averaging beyond all orders by giving exponential estimates of appropriately averaged and homogenised descriptions. Methods include iterated averaging transformations, optimal truncation of asymptotic expansions and highly regular solutions (Gevrey regularity). Prototypical examples are reaction-diffusion equations with heterogeneous reaction terms or rapid external forcing, nonlinear Schrödinger equations describing dispersion management, and second-order linear elliptic equations.


As a result of Italy's industrial electricity market overhaul and deregulation, the national transmission grid is likely to be subject to increasing stresses, making security analyses and procedures - both static and dynamic - mandatory. Additionally, the increasing complexity of interconnected power systems and their related controls leads to the designation of precise and wherever possible, common - security standards, coupled with sophisticated analysis tools. The aforementioned scenario has prompted private development of an online dynamic security assessment system, whose characteristics the paper describes. A functional overview of the system's modules, ranging from data acquisition to processing and storage, as well as the display functions, is provide herein.


Abstract Relict communities of Rhododendron ferrugineum L. in Northern Apennines. — On the Apennines Rhododendron ferrugineum vegetates spontaneously only on the Tuscan-Emilian part, but particularly on the Northern side, on Cima Belfiore (1810 m), on Mount Prado (2053 m), on Mount Libro Aperto (1937 m). The Rhododendron stations are to be found on the Northern slopes of the Apenninic ridges at an altitude between 1750-1937 meters (Libro Aperto). They have the aspect and sometimes the same floristic composition, of the hypsophyle Vaccinium and Empetrum heaths covering almost alla the summits of the Tuscan and Emilian Apennines. The environmental conditions which have preserved these Apenninic Rhododendron heaths could probably be the abundant snowfalls, (precipitations over 2000 mm per year), the acidity of the soil derived from the Oligocene hard sandstone and finally to a certain degree of continentality.


ABSTRACT The linear production of consumer goods is characterised by mass manufacture by multinational enterprises and globally dispersed supply chains. The current centralised model has created a distance between the manufacturer and end user, limiting the opportunity for intelligent circular approaches for production and consumption. Through a mixed method approach, opportunities of circularity are explored for the consumer goods sector. The study presents four lenses to analyse three enterprises through a multi-case study approach to explore the potential of digital intelligence and redistributed manufacturing (RDM) as enablers of circular business models. In addition, the study examines whether Discrete Event Simulation can be used to evaluate the circular scenarios identified through quantifying flows of material that determine traditional economic value (cost/tonne). The mixed method approach demonstrates that, a qualitative systemic analysis can reveal opportunities for circularity, gained through implementing 'digital intelligence' and distributed models of production and consumption. Furthermore, simulations can provide a quantified evaluation on the effects of introducing circular activities across a supply chain.


The audit market is divided between two main categories of auditors: Big Four auditors and Non Big Four auditors. The general accepted opinion is that the former cover most audit services. The objective of the study is to quantify the share covered by Big Four auditors at the level of Romanian market. In this respect one collected and processed data obtained from the audited companies from the North-West Region of Romania which is considered representative for extrapolating the results at national level. After processing the data there were established 14 parameters that characterize the activity of financial auditors divided in three categories: Big Four auditors, Non Big Four auditors and professionals in the audit field which operate within their individual offices. In order to establish the market share for each category of auditors one took into consideration all analyzed parameters. This objective was achieved by applying a specific method of quantitative competitive analysis: the comparison matrix method. The findings show that Big Four auditors have a significant market share, without covering a majority share. The study allows us to establish a profile of the beneficiaries of audit services for each category of auditors.


A clear air turbulence (CAT) occurred on 30 December 2020 over Tokyo, Japan. The CAT was largely generated by breaking Kelvin‐Helmholtz (KH) instability waves in the free atmosphere. A regional numerical weather prediction model simulated the event with fine resolution (35 m). Onboard‐recorded flight data and a flight simulation were utilized to validate the meteorological simulation. The locations of the reproduced strong turbulence agree well with the regions where flights encountered turbulence on that day. In a simulation with the finest resolution, the KH waves and their breaking were resolved. When the resolution was finer, the turbulent eddies were stronger, causing meteorological effects on the airplanes. The response of a virtual airplane to the simulated turbulence was estimated using a flight simulation. By comparing onboard‐recorded data with virtual flight data, we confirm that turbulent eddies are reasonably reproduced.


 Quantitative HBsAg and HBV DNA assays were conducted on 512 sera specimens (307 males; 204 females; 1 unknown) at Quest Diagnostics. o HBsAg assay: The investigators modified a qualitative test for HBsAg (Ortho Vitros) by transforming signal-to-cutoff ratios to quantitative values. The analytic range of the new quantitative test was 0.05 to 25,000 IU/mL. o HBV DNA assay: HBV DNA concentration was measured using a real-time PCR assay (Roche COBAS TaqMan) with an analytic range of 10 to 1.0 x 10 9 IU/mL.


We introduce an analytical technique to solve strongly nonlinear oscillators with cubic and harmonic restoring force by using harmonic balance method (HBM). A set of nonlinear algebraic equations is appeared when HBM is imposed. In this paper, a power series solutions of these nonlinear algebraic equations gives desired results and to avoid numerical complexity. A very good agreement was found between approximate and numerical solutions, which prove that HBM is very efficient and produces high accuracy results. We found that, a second order HBM works very well and the excellent agreement of the approximate solutions with the numerical solutions. The advantage of this method is its simple procedure and applicable for many oscillatory problems arising in science and engineering.


X-ray investigations of tungsten nanopowder produced with wire electrical explosion (WEE) have been carried out. It was found that two polymorph phases, /spl alpha/-W and /spl beta/-W, are simultaneously present in the nanopowder. During annealing in argon, /spl beta/-phase is first amorphised and then disappears. In contrast to /spl alpha/-phase which does not practically differ from that of standard material, /spl beta/-W is characterized with microdeformations of the lattice (increased lattice parameter). It is assumed that it is a kind of excess energy storage in nanoparticles of electroexplosive tungsten.


The Analytical Hierarchy Process (AHP) is a decision-making tool that enables the user to significantly reduce the complexity of problems with competing variables. This process suits the important decision of selecting an engine package. In this paper, the AHP will be used to select an engine package for the Formula SAE (F-SAE) race car to achieve maximum track performance. In this paper the AHP was used to develop a suitability model to select the preferred engine package. The model prioritised six primary criteria and 11 sub-criteria based on their impact on engine performance. This model then tested four engine alternatives including; a single, twin, four and turbocharged single cylinder engine.
With best engine performance in torque, power and efficiency the turbocharged single cylinder – WR450F & GT15-V (turbocharger) was selected as the preferred engine package for the F-SAE race car. As the selected engine package, after careful integration into the race car, the WR450F & GT15-V will increase the vehicles performance in the F-SAE competition.


Since its debut in 2007, the Kindle has become synonymous with e-book reading devices. Although the Kindle was not the first e-book "reader," as these devices are commonly called, it quickly became the most successful. Even with competition from other devices such as the Apple iPad or the Indigo-Chapters Kobo, the Amazon Kindle still holds 55 to 60 percent of the e-book market. If Amazon continues to hold a majority of the e-book market, then its biggest competitor as the largest online store of print books will be itself. It is noteworthy then that in advertising the Kindle, Amazon stresses how the technology of its e-book reader is superior to the printed book while at the same time assuring its customers that the content of both objects is the same. This rivalry between a new medium (the e-book reader) and its predecessor (the printed book) is not uncommon. In fact, Jay David Bolter and Richard Grusin argue that this sort of rivalry, as well as its accompanying homage, occurs in all forms of remediation. Amazon, however, has taken the rhetoric of remediation and has used it explicitly in their advertisement for the Kindle. Instead of hiding the e-book's close relationship to the earlier medium of books, Amazon celebrates it and highlights both the rivalry and the homage involved in this act of remediation. This paper argues that the advertisement of the Kindle explicitly employs the rhetoric and language of remediation in an attempt to forge a stronger connection between the reading of a Kindle and a printed book. Examining the way in which the most successful e-book reader has been marketed is important because the advertising rhetoric


Recently the troubles related to the network security have often occurred attacks.It consists of two fundamental thinge;the monitoring and the access control.To monitor the network,we have installed the intrusion detectioin system and have managed it since 1998,For the second thing,we arranged three categories to classify all hosts (about 5000 hosts) at KEK according to their security level.To realize these three categories,we filter the incoming packet from outside KEK whether it has a SYN flag or not.The network monitoring and the access control produced good effects in keeping our security level high.Since 2000 we have started the transiton of LAN from shared-media network to switched network.Now almost part of LAN was re-configured and in this new LAN 10Mbps/100Mbps/1Gbps Ethernet are supported.Currently we are planning further speedup(10Gbps)and redundancy of network.Not only LAN but also WAN,network speed will be upgraded to 10 Gbps thanks to the strong promotion of IT by Japanese government,In this very high speed network,our current strategy will be affected and again the network security becomes a big issue,This paper describes our experiences in practice of the current strategy and management know-how together with the discussion on the new strategy.

Introduction The development and production of materials requires vigorous quality control of raw materials, additives, stabilizers, intermediate and finished products. The chemical composition of these is tightly connected with their specific characteristics and their chemical/physical/ mechanical properties. Monitoring key elements at lower concentrations is routinely applied to exploration programs, research and environmental projects and is strictly controlled to meet national and international regulations to avoid potential danger due to hazardous and toxic substances.


Long noncoding RNAs (lncRNAs) are functional RNA molecules which are longer than 200 nucleotides in length that do not encode proteins; instead, they regulate target gene expression at transcriptional, posttranscriptional, and epigenetic levels. LncRNAs play important roles in various biological processes such as dosage compensation, genomic imprinting, cell cycle regulation, and cell differentiation. Although their characterizations have been relatively straightforward with recent advances in modern biology, the functions of lncRNAs are largely unknown. Herein, we discuss the biological functions and research methods of lncRNAs.


Hemispherectomized subjects display a strong ear dominance for the pitch mixture of dichotic chords: The tone presented to the ear ipsilateral to the removed hemisphere is less salient in the dichotic sound image than is the contralateral ear tone [R. Efron, M. Dennis, and J. E. Bogen, J. Acoust. Soc. Am. 60, Suppl. No. 1, 550 (1976)]. Two possible causes for similar ear dominance seen in normal subjects are an asymmetry in the transducer properties of the two ears or an asymmetry in the way two basically symmetrical inputs are combined centrally [E.W. Yund and R. Efron, J. Acoust. Soc. 62, 607–617 (1977)]. Evidence for the former derives from the finding that the dominant ear tends to have a superior frequency resolving capacity [P.L. Divenyi, R. Efron, and E.W. Yund, J. Acoust. Soc. Am. 62 624–632 (1977)]. Evidence for the latter derives from the present experiments which show that, in hemispherectomized subjects, there is no difference between the frequency dl in the two ears. The results suggest the e...

A medium-power (800 A, 48/60 V) power plant for the continuous supply of telephone exchanges has been designed and constructed. Besides great versatility, this power plant features advanced ideas in its diagnostics and for setting the various control intervention thresholds. Particular attention is drawn to the use of a microprocessor device for power-plant management and for processing and to the presentation of all the data the operator needs for proper diagnosis of plant operation. A communications interface is integrated into the microprocessor device to allow connection to the supervision and control network.<<ETX>>


Any motion of robotic manipulator will disturb its base in space due to the dynamic coupling. Such a disturbance will produce the serious impact between the manipulator hand and the object. Moreover, the disturbance will affect the communication with the ground and power supply for the space robot. On the other hand, compensating the disturbance using the attitude control system will consume large fuel which is limit in space. Therefore, a novel approach based on genetic algorithms (GA) is developed to find a global optimal path of a space robotic manipulator in joint space in order to minimize the disturbance to the base of space robot. The planning procedure is performed with respect to all constraints, such as joint angle constraints, joint velocity constraints, joint angular acceleration and torque constraints, and so on. We use GA to search the optimal joint inter-knot parameters in order to realize the minimum disturbance. These joint inter-knot parameters mainly include joint angle and joint angular velocities. We use an illustrative example to verify that GA-based optimal path planning method has satisfactory performance and real significance in engineering


The performance of system-on-chip is determined not only by the performance of its functional units, but also by how efficiently they cooperate with one another. It is the on-chip communication architecture which determines the cooperation efficiency. Network-on-Chip (NoC) is introduced to improve communication bandwidth and power efficiency. However, traditional metallic interconnects consume significant amount of power to deliver large communication bandwidths. Optical NoCs are based on silicon optical interconnects with significant bandwidth and power advantages. Optical routers are the key enabling components of optical NoCs. This paper proposed a novel optical router architecture, ODOR, for optical NoCs based on XY routing algorithm. We compared ODOR with four other router architectures, and analyzed three aspects in details, including power consumption, optical power insertion loss, and the number of microresonators. The results show that ODOR has the lowest power consumption and losses and requires the least microresonators. ODOR has 40% less power consumption, 40% less loss, and 52% less microresonator than the full-connected crossbar. Furthermore, ODOR has a special feature which guarantees the maximum power to route a packet through a network to be a small constant number, regardless of the network size. The maximum power consumption is 0.96fJ/bit under current technology. We simulated a 6x6 2D mesh NoC based on ODOR, and showed the end-to-end delay and network throughput under different offered loads and packet sizes.


: The Sundarbans, the world's largest mangrove forest, plays a crucial role in Bangladesh's economy and environment. However, overexploitation, anthropogenic activities like tree cutting for development and agriculture, as well as natural disasters, have caused severe damage and changes to the Sundarbans. This research aims to detect changes in the mangrove forest areas and create an above-ground biomass map of the Sundarbans Forest. Previous studies relied on time-consuming and inaccurate traditional methods, while this study seeks to make a significant contribution to mangrove mapping and forest resource management. Landsat 5 and 8 images from 2007 to 2017 were used to generate the mangrove index (including CMRI and MI) for different years. ALOS-PALSAR 2 and JERS images from 1996, 2007, and 2017, with HV+HH polarization, were processed to calculate the backscatter ratio, enabling identification and estimation of vegetation loss and gain over the years. To estimate the above-ground biomass (AGB), tree height was derived from SRTM DEM, and an allometric equation was used to calculate AGB. The results indicate a continuous shrinkage of the mangrove forest. The 2017 maps of the two different indexes reveal significant mangrove vegetation loss compared to 1996 and 2007. Additionally, the study estimates the total above-ground biomass of the Sundarbans mangrove forest to be 329 million tons. The findings can assist relevant authorities in taking necessary action, formulating policies, and implementing plans for sustainable management of the Sundarbans


Mastitis in China is a common condition in breastfeeding as well as non-breastfeeding women. The causes of mastitis include congenital dysplasia, pathogen, and other diseases such as diabetes. The present study analyzed the main cause of mastitis and evaluated the antibiotic resistance patterns in cases with pathogen tested as positive. A total of 366 women were recruited in this study between October 2011 and May 2014. The abscess samples were obtained from the cases of mastitis with a breast abscess. The bacteria from these samples were isolated and cultured and isolated. Finally, the drug sensitivity of these cases was assessed by antibacterial susceptibility testing (AST). The congenital nipple dysplasia comprised of 52.9% (126/238) breastfeeding cases, while the non-breastfeeding bacterial infection comprised of 40.6% (52/128). The bacterial susceptibility test showed that the pathogen in both breastfeeding and non-breastfeeding cases showed extensive resistant to clindamycin, erythromycin, and penicillin. The rate of drug resistance in bacteria was lower in breastfeeding cases as compared to that in non-breastfeeding cases (P<0.05). The results showed that for the breastfeeding mastitis, the main cause is congenital nipple dysplasia, and bacterial infection in non-breastfeeding cases. For breastfeeding cases, emptying the breast and using ciprofloxacin, levofloxacin, and gentamicin as empirical choices before obtaining bacterial susceptibility test results is recommended. For non-breastfeeding cases, Oxacillin and Moxifloxacin could be used as empirical treatment.

The advancement of internet technology has played an important role for people to receive information and the number of internet users has increased rapidly. Hence, e-commerce has exploded in recent times, with entrepreneurs using the internet more frequently to buy goods for their businesses and to sell their own products. However, there are few studies that study opportunity recognition in internet entrepreneurship. Therefore, in this research, we investigate how human capital of web-entrepreneurs including motivation, experiences, education and creativity influences their ability in recognizing opportunities and further influences new venture performance. There are 484 web-entrepreneurs responding to our questionnaire; and the results were analyzed by using structural equation modeling. The key finding highlights that web-entrepreneurs' entrepreneurial motivation, entrepreneurial experience, and creativity are positively correlated to opportunity recognition. Interestingly, entrepreneurial education is not significantly related to opportunity recognition. In addition, opportunity recognition and new venture performance are positively correlated.


Objective: To study the radioimmunoassay(RIA) of leptin(LPT) in clinical use. Methods: Anti-LPT serum was produced by repeated stimulation of small dose rhLPT to New Zealand rabbits. 125I-LPT was iodinated with BH reagent by indirect iodination labelling,and then RIA of LPT was established in clinics. Results: The working dilution of anti-LPT serum was 1 ∶ 6 400; the specific radioactivity of 125I-LPT was 1.43 MBq/μg, the total labeling rate of 125I was 37.8%; the technical specifications of RIA of LPT could satisfy the needs of RIA; the assay values of normal male and female was (4.9±2.7)μg/L and(8.9±4.0)μg/L respectively with marked sex difference (P0.01). Conclusion:The test specifications of RIA of LPT could satisfy the clinical needs for reducing the harm of direct iodination to LPT.


Transmitted torque of permanent magnet couplers (PMCs) is the core index to evaluate its transmission performance. A semi-analytical calculation method for transmitted torque of the PMC is established to solve those problems that the analytic method is difficult to fully consider the specific details of the three-dimensional (3D) PMC, the calculation accuracy is insufficient, and the finite element model (FEM) has numerical oscillation and the calculation accuracy is float. The analytical model and the FEM are combined in this method, can effectively calculate and predict the transmission performance of the permanent magnet coupler. First, according to geometric structure, a magnetic equivalent circuit model is established to solve internal magnetic induction intensity. Based on the relationship between the eddy current density and the magnetic induction intensity, and considering the 3D end effect, an analytical model of transmitted torque is constructed. Second, a 3D FEM of the unipolar PMC is established, and the transmission performance by the finite element calculation is obtained. On this basis, using the entropy method to combine the magnetic circuit equivalent model with the FEM, a semi-analytical calculation method for the transmitted torque is presented. Finally, an experimental platform is built to verify the method. The results show that under normal working conditions, the proposed method for calculating the transmitted torque has a good consistency, and the relative error is within 6.5%. This method can provide a theoretical basis for the analysis, design, and optimization of PMCs.


Let G be a finite group and let X be a compact G-space. In this note we study the (Z+ × Z/2Z)-graded algebra
FqG (X) = ⊕n ≤ 0 qn · KG∫Gn(Xn) ⊗ C,
defined in terms of equivariant K-theory with respect to wreath products as a symmetric algebra, we review some properties of FqG (X) proved by Segal and Wang. We prove a Kunneth type formula for this graded algebras, more specifically, let H be another finite group and let Y be a compact H-space, we give a decomposition of FqG × H (X × Y) in terms of FqG (X) and FqH (Y). For this, we need to study the representation theory of pullbacks of groups. We discuss also some applications of the above result to equivariant connective K-homology.


Objective The aim of this study was to investigate the effectiveness and tolerability of escitalopram, a selective serotonin reuptake inhibitor versus black cohosh, Cimicifuga racemosa, for the treatment of hot flashes among menopausal women. Background Hot flashes are one of the most agonizing symptoms of menopause, involving about 80% of women. Because of recent controversies about black cohosh as an alternative herbal treatment for hot flashes, the use of antidepressants to treat hot flashes has been an active area of research. However, most of the previous trials have included women with medical or psychiatric disorders that may affect drug response. Patients and methods A total of 104 menopausal women aged 50–60 years were enrolled into randomized clinical trial. The women received either escitalopram or black cohsh with follow-up at 4 and 8 weeks. After 4 weeks, cases not reaching 50% reduction of hot flashes were treated with double the dose of either escitalopram or black cohosh. The main outcome measures were the frequency and severity of hot flashes using the Greene climacteric scale. Results Over the course of the study, women reported significant decreases in both hot flash frequency and severity in the escitalopram group than in the black cohosh group (P=0.0001). Differences in decrease in hot flashes severity were significant as well (P=0.002). Both have similar safety profile. Conclusion Escitalopram 10–20 mg/day is more effective compared with black cohosh at a dose of 20–40 mg/day for reducing hot flashes (frequency and severity) in nondepressed menopausal women; both are tolerable and safe.


P .008), and T-cell depletion (TCD) at transplantation (RR 21.9, P .011) were found to be independent predictors of GVHD after DLI. Although there is more AGVHD associated with patient-donor sex mismatch, in the mismatch-only group there is considerably more AGVHD associated with the use of BDR than with EDR (9 of 16 patients vs 2 of 11 patients, P .048); this explains why sex mismatch is not significant in the multivariate analysis. Our findings demonstrate that most of the factors known to be associated with AGVHD after allogeneic SCT are not predictive of AGVHD following DLI. Our data reinforce the notion that DLI can be safe if the effective cell dose is administered late after transplantation3,7; this has important practical implications for the use of DLI in the context of reduced-intensity conditioning SCT.


This paper establishes the shape function of high-pier with non-ideal boundary conditions in the top and uses the energy method to calculate its critical load. Then its effective length factor is achieved by using Euler's formula. Further, the FEM and energy method are respect used to calculate the effective length factor of the engineering example and comparative analysis is carried on. Results show that: The non-ideal boundary conditions have great influence on the effective length factor and should be considered in the calculation. The result from the formula of energy method is nearly the same as the one from the FEM which demonstrates this method is of good accuracy to calculate the effective length factor of high-pier. In addition, it is also of great convenience in the design of high-piers.


Summary form only given, as follows. A new linear induction electron accelerator called DRAGON-I is now being studied and designed at CAEP. The high performance required for the accelerator is tightly connected to the high performance of injector A 3.2 MV/spl sim/3.5 MV injector, extracting at 90 nanosecond (60 ns flat), 2.5 kA/spl sim/3.5 kA electron beams has been studied and the parameters indicating the beam quality have been or are being measured. Among the parameters, the emittance is regarded as most important one. This paper relates the electron beam emittance evolution by PIC code. The relationships between emittance and velvet recess, emittance and beam current, emittance and external magnetic field, emittance and transport distance, etc., are discussed by simulation using PIC method. We wish to draw a conclusion form the emittance evolution and minimize the emittance of injector.


To the Editor.— It is the purpose of this communication to note two significant therapeutic uses of fist punches. Wild and Grover 1 recently described the use of the fist as external cardiac pacemaker. They reported that in three patients with ventricular asystole the heart responded to chest pounding, in one case for more than 40 minutes. Each blow on the chest was followed by ventricular depolarization and systole. The authors suggest that this method may be tried as an immediate treatment for asystole in the hospitals and indicate that outside the hospitals it worked better than cardiac massage as first-aid for cardiac arrest. Death at the dinner table from choking on food, following a sudden onset of cyanosis, and weak, spasmodic breathing in a healthy person is commonly misdiagnosed as "cafe coronary." I have reported two cases to point out the importance of correct diagnosis of choking and its


A theoretical treatment of binocular space perception based on the methods of Rudolph K. Luneburg. A simplified axiomatics is employed. New experimental results are brought within the framework of the theory. The experimental evidence is seen to support Luneburg's hypothesis as to the hyperbolic character of visual space. The relation between visual and physical coordinates proposed by Luneburg is found to hold only as a special case of a more general transformation.


With the steady improvement in the socialist market economy and China's imminent entry into WTO, higher education, as an industry, will inevitably be involved in the trend of market economy for oompetition. As a cradle of the country's talents, higher educational institutions are making every endeavour so as to improve them-selves in the competition. Apparently, this situation presents a challenge to the teaching- material - construction work, which exerts a direct influence upon the result and quality of teaching and even the quality of studente. Therefore, it is necessary that we know how to do the work and adapt it to the present situation of reform and de-velopment, and that we should establish an operating mechanism applicable to the market economy. We should learn from the experience in enterprise management, making use of the modem equipments in management technol-ogy. In one word, we should endeavour to improve the work efficiency and push forward the teaching-material -construction work to a new stage.


We prepared a series of blend membranes by blending waterborne polyurethane (WPU) and carboxymethylchitin (CMCH) in aqueous systems. The effects of CMCH content on the miscibility, morphology, thermal stability, and mechanical properties of the blend membranes were investigated by dilute solution viscometry (DSV), Fourier transform infrared spectroscopy, wide-angle X-ray diffraction (WXRD), scanning electron microscopy, dynamic mechanical analysis (DMA), thermogravimetric analysis, ultraviolet (UV) spectroscopy, and tensile testing. The miscibility parameter of the WPU/CMCH aqueous solution obtained by DSV predicted that the blends of WPU and CMCH were miscible or partially miscible. Moreover, the partial miscibility of the blend membranes over the entire composition range were confirmed by FTIR, WXRD, DMA, and UV spectroscopy to support the conclusion from DSV. New hydrogen bonds were formed between CMCH and WPU in the blend membranes, resulting in strong intermolecular interactions. By inducing the CMCH, we improved the tensile strength, thermostability, and organic solvent resistance of the blend membranes significantly. Therefore, this study not only provided a novel way to prepare an environmentally–friendly material but also expanded the application of chitin and CMCH. © 2003 Wiley Periodicals, Inc.

Data augmentation plays an indispensable role in expanding datasets and preventing neural network overfitting. In this paper, we analyzed the advantages and disadvantages of information dropping and information mixing methods in data augmentation. Then we combine the advantage of information dropping and information mixing, and propose Gridcut and Gridmix. Gridcut is based on the structured deletion of the input images like Gridmask. The size and shape of the deleted areas can be flexibly adjusted according to the Characteristics of the dataset. Based on this Gridcut, Gridmix interpolates pixel information of other images on the deleted areas. Comparative experiments demonstrate that our methods outperform the state-of-the-art augmentation strategies on CIFAR classification tasks. By adjusting the parameters, our method can also be flexibly expanded into Cutout, Cutmix and Gridmask.


In this paper, we propose a novel stacked autoencoder (SAE) based operation mode classification method for the complicated industrial process. In detail, we first add the sparse and regularization constraints into SAE to learn low-dimensional nonlinear representations of high-dimensional data, then the SAE is trained in two steps: unsupervised layer-by-layer pre-training is performed first, followed by supervised fine-tuning. In order to evaluate the efficiency of the proposed method, we conduct extensive experiments on the Tennessee Eastman (TE) process and aluminum electrolysis production process in comparison with several conventional methods, the experimental results validate that the proposed method is more effective than other methods in the mode classification task.


Low birth weight is a leading cause of childhood morbidity and mortality globally, especially in low- and middle-income countries. Individual trace element exposure during pregnancy is associated with birth weight; however, information on potential mixture effects of multiple-elements exposure on birth weight are limited. In this study, we assessed the effects of single element and element mixtures on birth weight among 745 mother-infant pairs from a prospective birth cohort established in Bangladesh from 2008 to 2011. Using inductively coupled plasma mass spectrometry, we measured 56 elements in cord blood collected at delivery. Multivariate linear regression was used to evaluate the individual effect of element exposure on birth weight. Then, we also applied regression model based on categorical variables according the interquartile range (IQR) and restricted cubic spline to explore potential non-linear associations. Bayesian kernel machine regression (BKMR) and weighted quantile sum (WQS) regression were used to assess the mixture effects on birth weight. We found significant negative associations between exposure to lithium (Li), manganese (Mn), cobalt (Co), copper (Cu), yttrium (Y), and erbium (Er) and birth weight, while the concentration of selenium (Se) was positively associated with birth weight. Li was identified as the most important predictor of birth weight by WQS regression and cumulative exposure to element mixtures (Li, Mn, Cu, Co, Y, and Er) was associated with decreased birth weight, birth weight decreasing by 64.73 g with per each unit increment of the element risk score (ERS) based on WQS. Interestingly, the presence of Se during pregnancy may attenuate the risk of low birth weight by its main protective and antagonistic effects against toxic elements.

The paper addresses the problem of bit-rate conversion of MPEG compressed video. We present selective requantization, a method for reducing the requantization errors in transcoding. The proposed method is based on avoiding critical ratios of the two cascaded quantizations (encoding versus transcoding) that either lead to larger transcoding errors or require a higher bit budget. Results show that selective requantization improves the quality of the transcoded images. The presented method is simple to implement and does not require side information.


The Interior Design courses emphasizing accuracy requires high learning motivation. One stimulus to grow motivation is by applying teaching methods that are in accordance with the characteristics of the course, namely cyber learning methods that also facilitate accuracy and efficiency.
 The purpose of this research is to improve learning motivation in interior design courses through cyber learning methods employing steps of project-based learning (PjBL). The study included quasiexperiments using two-group post test design. The instrument of learning motivation was adapted
 from McClelland's motivational theory. The number of participants was 60 students divided in two groups. The first students group learned by using conventional methods (control group), while the second students group learned by using cyber methods (experimental group). The number of
 learning was 10 meetings. After completing the meetings, the two groups were measured based on the learning motivation. The results of the study indicate that cyber learning methods can increase student's learning motivation in interior design courses. Result shows that the experimental
 group of students has higher learning motivation than students in control group who were leaved uninterfered with the conventional method—the lectures.


After every Shuttle mission, the Solid Rocket Boosters (SRBs) are recovered and observed for missing material. Most of the SRB is covered with a cork-based thermal protection material (MCC-l). After the most recent shuttle mission, STS-114, the forward section of the booster appeared to have been impacted during flight. The darkened fracture surfaces indicated that this might have occurred early in flight. The scope of the analysis included microscopic observations to assess the degree of heat effects and locate evidence of the impact source as well as chemical analysis of the fracture surfaces and recovered foreign material using Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy/Energy Dispersive Spectroscopy. The amount of heat effects and presence of soot products on the fracture surface indicated that the material was impacted prior to SRB re-entry into the atmosphere. Fragments of graphite fibers found on these fracture surfaces were traced to slag inside the Solid Rocket Motor (SRM) that forms during flight as the propellant is spent and is ejected throughout the descent of the SRB after separation. The direction of the impact mark matches with the likely trajectory of SRBs tumbling prior to re-entry.


Leaders are responsible for allocating and managing resources for agility and absorption. The orange world may mean short-term careers, but short-term projects, with key leaders as the core of the organization who remain for long periods. In the blue world are global influencers. Capitalism is leading growth, and employees have everything they need to develop innovation, health insurance, and technology. In this blue world, leading and seeing people is the most important asset. The corporation will develop corporate cultures that empower the workforce and quality of life for employees. The green companies develop a powerful and influential social conscience and sense of responsibility. Often consumers will demand this by lobbying for a change in corporate behavior. Green companies develop strong controls over their supplier networks and demand ethical practice from all vendors in their supply chains. With the world becoming more complex and turbulent, now more than ever we must look at how we frame and reframe our organizations to fit the future. This chapter explores international programs and possibilities.


We present the fabrication and testing of the Sub-orbital Local Interstellar Cloud Experiment (SLICE), a rocket-borne payload for ultraviolet astrophysics in the 1020 to 1070 Å bandpass. The SLICE optical system is composed of an ultraviolet-optimized telescope feeding a Rowland Circle spectrograph. The telescope is an 8-inch Classical Cassegrain operating at F/7, with Al optics overcoated with LiF for enhanced far-ultraviolet reflectivity. The holographically-ruled grating focuses light at an open-faced microchannel plate detector employing an opaque RbBr photocathode. In this proceeding, we describe the design trades and calibration issues confronted during the build-up of this payload. We place particular emphasis on the technical details of the design, modifications, construction, and alignment procedures for SLICE in order to provide a roadmap for the optimization of future ruggedized experiments for ultraviolet imaging and spectroscopy.


observed in 120 of these villages. The soil samples (n=2,447) were sent to the Eskişehir Osmangazi University. Of these samples, 1,251 were subjected to mineral analysis at the TUBITAK Marmara Research Centre Material Institute with an XRD. As a result, 379 samples were found to contain fibres. According to the registers for the period of 2012 and 2013, 158,068 people lived in these rural areas/villages. Apart from the settlements with a population of more than 1,000 people, the number of those people living in these areas is 98,453. These populations include the cases with asbestos exposure and who would continue to be exposed to asbestos if no preventive measure is taken. Moreover, the population exposed to asbestos for a risky period of time in terms of related diseases that may lead to 3,718 mesothelioma cases was estimated to be 571,460. Thus, the population exposed to asbestos for a risky period of time and the one who continues to be exposed to asbestos in rural areas was estimated and identified. It was projected that 15,450 mesothelioma, 5,737 lung cancer, 82,290 pleural plaque, 59,431 diffuse pleural fibrosis, and 2,286 asbestosis cases will emerge in the population exposed to asbestos for a risky period of time in the abovementioned rural areas. Moreover, it was projected that 2,511 mesothelioma, 1,322 lung cancer, 17,344 pleural plaque, 12,526 diffuse pleural fibrosis, and 482 asbestosis cases will emerge in the population who continues to be exposed to asbestos between 2013 and 2033. OCCUPATIONAL ASBESTOS EXPOSURE: In the Plan, 1,879 cases who were diagnosed with mesothelioma between 2008 and 2012 but were not born and/or living in the village are among the patients with mesothelioma who are under a heavy risk of occupational exposure. These cases should be examined based on occupation and workplace, and in line with the obtained data, the existence of the occupational asbestos exposure should be analyzed.


[This article examines the influential decision of the House of Lords in Morgan, where a charge of rape was contested on the ground that the accused had believed the victim to be consenting to sexual intercourse. The majority decision that a man's belief in consent, regardless of its reasonableness, is a good defence to a charge of rape is considered, with particular reference to the concept of criminal negligence and the doctrine of mistake. It is argued that the decision is untenable, both in terms of formal precedent and the liberal philosophical premises underlying the criminal justice system.]


This thesis is focused on reducing the gap between the acquisition of low-level information by robot sensors and the need of obtaining high-level information for enhancing human--machine communication and for applying logical reasoning processes. To this end, approaches for qualitative and semantic image description and qualitative distance sensor interpretation were developed. Experimentation was carried out on different robotic platforms showing useful applications.


Peer-to-peer (P2P) networks have in the past years become a very attractive method for delivery of media content over the Internet. Many factors have contributed to this success, but the low delivery costs and the inherent scalability of the P2P networks whereby consumers of content are also potential sources are among the most prominent ones. However, the effectiveness and performance of many popular P2P networks (such as BitTorrent based ones) is highly dependent on how well trackers select peers that will provide a content. The peers chosen by a tracker will directly affect the user-perceived performance of the service and the usage of network resources. Moreover, P2P networks have usually no locality awareness, resulting in sub-optimal utilization of network resources. In order to address these issues, we propose a novel hierarchical architecture for P2P locality targeted at managed P2P networks based on the BitTorrent protocol. We then show, through experimentation, that the adoption of the proposed architecture leads to significant network efficiency improvements without compromising end-user experience.


Purpose The objectives of the study are to examine the customer choice of preference among the various marketing strategies (Social Media, MMS/SMS, advertisement through newspapers, magazines, etc.); to investigatethe awareness of social media marketingand, to find out the preferred social media platform and the security concerns of the customers with respect to such platforms. Design/methodology/approach The sample survey was involving both qualitative and quantitative methods of data collection. 202 samples were collected through a well-defined questionnaire. The sample included 102 customers of the Mall, 50 university students (both of these samples were selected on a convenient sampling basis) and 50 residents from Safeer vicinity (selected on a simple random sampling basis). Findings The empirical results reveal that an easy and good means to influence the customers of the mall is through social media marketing. The study also reveals that the customers do not feel secure through social media, as their identities might be stolen or misused. The study confirms that the customers do not perceive social media marketing as an attractive and effective tool as they still prefer the traditional methods. Practical Implications The study confirms that it is good means to approach the customers of the mall through social media marketing as the customers can easily be influenced which will boost the business in an easier way. Social Implications The study emphasizes on the mall's participation and posting of more contents to their social media pages, clarifying the customers on the security issues. The malls should use social media marketing along with the traditional marketing method so as to cope up with the preferences of the customers. Originality/value No study has investigated the awareness and the preferences of the social media marketing platforms of the malls of Oman, and this study will help the malls to plan on the new marketing avenues and techniques.


The border trade has been synonymous with the development of different states from antiquity; However, with the passing of the years this trade has been increasing and it is causing a series of problems in the trade balances of countries.

Art. 166 of the Organic Code of Production Trade and Investment literally states "Art. Traffic Fronterizo.- 166. According to international commitments, the exchange of goods for domestic use or consumption between the border towns, free of formalities and the payment of taxes on foreign trade is allowed, within the limits of the Service National Customs".

This provision or the spirit of it is currently not being met because today near the border populations of one or another way unscrupulous people have made their way of life through the border looking for-profit trade and without respecting the limits.

This has caused a number of people or families living near the border, even those who have not live in the border areas, are engaged in informal trade of goods without paying taxes and have taken advantage of this legal standard that will benefit a certain group of people, which certainly brings some serious consequences to the economy of our country and a deficit in the trade balance.

The current legal standard of Art. 169 of the Organic Code of Production Trade and Investment, has made the borders with Colombia and Peru are much sought or desired by people who have done great business through smuggling and without paying taxes to the Treasury , taking advantage of the aforementioned rule will benefit the inhabitants of the sector and to meet their basic needs


Abstract : Metal matrix composite use has been impeded because there is no well qualified property data base. Elevated temperature compressive properties and laser absorptivity data are in great demand in the design, modelling, and analysis of MMC structures in elevated temperature applications and survivability assessment. Testing methods were developed for room temperature and elevated temperature compressive modulus and strength measurements of single-ply unidirectional graphite-aluminum (Gr/Al) and graphite-magnesium a(Gr/Mg), and to generate laser absorptivity data for these two types of materials. An effective gage length was established for valid compression tests to eliminate buckling failure. The measured failure strength values for Gr/Al and Gr/Mg are approximately 50 to 60% lower than the material tensile strength. Small gage strain gages are being used to measure the compressive modulus as a function of temperature. The laser absorptivities of Gr/Al and Gr/Mg were measured by the use of an in-house developed differential calorimeter. The calorimeter has been used to measure total hemispherical emittance and normal laser absorptance of specimens as a function of temperature from 200 to 700 C. Test results indicated that the laser absorptances of Gr/Al and Gr/Mg at 10.6 micrometer wavelength remain more or less constant over most of the temperature range tested. 888

Global climate change has already had observable effects on the environment. Hotel industry has a role to play mitigating climate change by reducing carbon emissions. This article explores the energy saving potentials in hotels by simulating several currently available scenarios at different climates by using methodical and iterative processes to evaluate potential decisions and achieve long-term goals. The information provided in this research work is based on a review of relevant literature and the results of EQUEST simulations for 3 hotels certified with LEED V3 across Turkey. Three locations were selected to represent the three climate zones in Turkey. Green criterias are evaluated according to LEED V3 certification system. Based on the findings presented in this paper, it is suggested there exists significant energy savings potential for the Turkey's hotel industry if hotels are designed and built with sustainability principles. The main finding after compairing the three hotel designs is that it is technically feasible to increase energy efficency more than 60% without compromising guest comfort by using green technologies. Because the number green design and construction of new constructed hotels is low, implementing a new green building code with strict energy requirements is recommended for those developers who do not want to certify their hotels.

In short in this paper we design and develop a framework for Big Data analytics using RestFul Web Services


This issue of the Cambridge Quarterly is dedicated to the memory of Jonathan Mann. He was an inspired leader in the global struggle against AIDS and a creative intelligence envisioning the integration of the goals of medicine, public health, and human rights. In a memorable keynote address to the Third World Congress of Bioethics held in San Francisco in 1996, he challenged this community to bring its expertise to contribute to a broader, more social, and more global conception of healthcare than is common to our thinking. Jonathan's tragic death in the crash of Swissair Flight 111 in September 1998 took from us a beacon of insight and an active collaborator in this exciting prospect. His vision of justice and of the essential integration of the sciences of humanity has inspired this collection of essays. We offer it to his memory in gratitude and admiration.


In this paper, spatial‐alternated Julia sets are discussed, which are obtained by alternating the spatial‐alternated system, and plane‐alternated Julia sets are discussed, which are obtained by alternating the plane‐alternated system. The control of spatial‐alternated Julia sets and plane‐alternated Julia sets is achieved via the optimal control. Moreover, the synchronization of two different plane‐alternated Julia sets is implemented via the optimal control. The simulations illustrate the effectiveness of the control method.

In this paper, a new implementation of an electronically tunable resistor-less floating inductance simulator using a second-generation voltage conveyor (VCII) is presented. The proposed circuit is resistor-free (benefiting from the intrinsic resistors at the Y terminals of the employed VCIIs) and composed of three VCIIs and a single grounded capacitor. Using a control current (Icon), the value of impedance at the Y terminal of the VCII is varied, whereby the value of the simulated inductance is tuned. The proposed circuit is designed at a transistor level using 0.18 µm TSMC CMOS parameters and ±0.9 V supply voltage. PSpice simulations are carried out to confirm the effectiveness of the proposed circuit. For a range of Icon from 0 µA to 50 µA, the value of the simulated L can be varied from −576 µH to −324 µH and from +316 µH to +576 µH for negative and positive simulators, respectively, in the frequency range of 100 kHz–3 MHz. Favorably, the value of the series resistance remains below 76 Ω. Simulation results show an error value below 4.8% and power consumption variation is from 1.64 mW to 1.92 mW. Moreover, application of the proposed circuit as a standard band-pass RLC filter is also included.


The debate has intensified regarding the possible risks linked to cardiovascular imaging. This discourse has been triggered by the increased utilization of imaging procedures and modalities including cardiac computed tomography (cardiac CT). Should the risks associated with cardiac CT discourage the physician or patient from having the procedure performed? Is the increased cost (due to the imaging procedures) balanced by the benefits to the doctor and for the patient for such services? The risks, particularly radiation, are there; but the benefits of improved diagnosis and earlier, more effective treatment seem to outweigh the risks.


The objective of this work is to prepare an Activated Carbon (AC) from eucalyptus sawdust, having an important pore structure and the best chemical properties for the removal of Methyl Orange (MO) and chromium (Cr-VI) in an aqueous medium. The materials were activated with zinc chloride (ZnCl2). The latter were characterized by thermogravimetric analysis, differential thermal and differential scanning calorimetry (TG-DTG-DSC), Fourier transforms infrared (FTIR), pH at zero charge point (pHPZC), iodine number (II2), and methylene blue number (IMB). The evaluation of adsorption capacity consisted of discussing the effects of contact time, solution pH, and the effect of temperature using a batch adsorption technique. In addition, different kinetic models (first-order, second-order, and Intra-particle diffusion) and adsorption isotherms (Langmuir, Freundlich) were applied. Analysis of the TG curve illustrates the presence of hemicellulose, cellulose, and lignin, thus confirming the lignocellulosic structure of Eucalyptus Sawdust. Samples AC1/1, AC1/2, and AC1/3 prove to be the best absorbents. The measurement of their iodine numbers gave, respectively II2 (1269.000, 1395.900, and 1395.900 mg/g) indicating a better microporosity and the specific surface area by iodine adsorption (SI2, 1282.900, 1411. 200, and 1411.200 m2/g) justifies the development of porosity. The pseudo-second-order kinetic model better describes the adsorption of MO and chromium (VI) on AC with R2 = 1 for MO and R2 ≥ 0.9996 for chromium (VI). The thermodynamic study gave negative values of free energy which justify the feasibility and spontaneity of the adsorption process of MO and chromium (VI) on AC, the positive values of free enthalpy and entropy reflect that the process is endothermic and reflect the good affinity of chromium (VI) on AC due to pore swelling, whereas, negative values indicate that the process is exothermic and indicate an increase in order at the solid/liquid interface. The heat of adsorption value (ΔH°> 42 kJ mol-1) indicates that the chromium (VI) adsorption process on AC is chemical. On the other hand, the adsorption of MO on AC (ΔH° < 42 kJ mol-1) is of the physical type.

Ijsrm.Human, 2022; Vol. 21 (3): 48-76. 49 INTRODUCTION In recent decades, many chemical molecules have been detected and quantified in natural waters and advances in toxicology and epidemiology allow their effects on health to be assessed. Most of these new substances come from the increased production and use of derived natural compounds (fertilizers, metals), as well as new synthetic molecules (pesticides, pharmaceuticals, cosmetics) [1]. Organic pollutants, whether of natural or anthropogenic origin, are dispersed in various compartments of the environment and are likely to seriously affect natural ecosystems and ultimately human health [2]. Adsorption remains one of the most widely used pollutant removal techniques due to its efficiency, ease of implementation, and affordable investment cost. This method requires the choice of an adsorbent having good properties such as zeolites or polymer resins, silica gels, activated aluminas, and Activated Carbon (AC) [3]. AC is cited preferentially among the many materials considered to be the most promising for the elimination of organic and mineral micropollutants [4]. Various studies have been devoted to the production of activated charcoals from lignocellulosic biomass: grape seeds[4], almond shell [5], coconut shell [6], date pits [7], peach stones [8], woods [9], pods of Flamboyant delonixregia [10]. AC is obtained either by chemical activation or by physical activation. The physical activation takes place in two stages and at high temperatures between 400-900°C, unlike the chemical activation which takes place at the same time as the carbonization under an inert atmosphere between 400 and 600°C, after impregnation of the precursor by an activating agent such as phosphoric acid [11], zinc chloride [12], alkaline carbonates [13], potassium hydroxide [14], and more recently sodium hydroxide [15]. The chemical activation is followed by the heat treatment step, and finally by a washing step to remove chemical agents and the products of inorganic reactions [16]. The main objective is to prepare activated carbon from eucalyptus sawdust, having an important pore structure and the best chemical properties for the reduction of Methyl Orange (MO) and Chromium (Cr-VI) in an aqueous medium. As a specific objective, we will prepare activated carbons from eucalyptus sawdust by chemical activation with Zinc Chloride (ZnCl2), www.ijsrm.humanjournals.com Citation: Pierre Gerard Tchieta et al. Ijsrm.Human, 2022; Vol. 21 (3): 48-76. 50 characterize them, and test the performance of activated carbons prepared for the removal of MO and Cr-VI in an aqueous medium. The adsorption study consisted of discussing the effects of contact time and the pH of the solution using a batch adsorption method. The effect of temperature made it possible to carry out a thermodynamic study to define the nature of the absorption phenomenon. In addition, different kinetics models (first-order, second-order, and Intra-particle diffusion) and adsorption isotherms (Langmuir and Freundlich) were used for the evaluation of adsorption capacity.


This study investigates the case that music is a powerful tool for developing motor skill in young children in an aquatic environment. To establish this it first looks at the role music has taken in human society and then specifically at the relationship young children have with it. By analysing two existing nursery rhymes it identifies common musical devices used and then sets about creating nursery rhymes to accompany specific exercises in a parent and baby swimming class. By looking at the progression of these children through the stages of acquisition of skill according to Fitts' stage theory of motor learning it shows that these songs have helped the progression of the children and explains the reasons behind this.

It concludes that we can make emotional associations with songs using rhythm and melody, and associate different sounds with different gross-motor skills in younger children, until their communication skills have progressed far enough for them to listen to the lyrics and the songs can facilitate the learning of exactly what it is they should be performing.


Biogas energy is an important energy type in terms of both the advantages it provides during the use phase and the source of raw materials in our country compared to other renewable energy sources. In our country, it is seen that there is a big difference in the energy potential obtained from the biological origin wastes and the amount of energy provided from these wastes. In this case, considering our external dependence on energy, it is understood that the use of biological wastes in more energy production should be expanded. In this study, according to Turkish Statistical Institute (TUIK) 2017 data, the average age, dry matter and energy potential values of walnut groves grown in the districts of Tokat province were determined. Within the scope of the study, total average age waste potency of the province of Tokat; 158.049 tons/year, the average amount of dry matter potential; 48.293 tons/year and the average energy potential amount; 22 607 TEP/year .


A real-time fault detection and identification(FDI) scheme of time-variant signals for a complex system was studied.A sliding-window Mallat wavelet fast transform was first introduced to avoid depending on the signals in all periods for the classical wavelet transform,and the computing effect was improved,which makes sense that the real-time fault detection is effective.Secondly,aimed at the problem that it is difficult to identify the fault by using time-variant signals,an improved dynamic recurrent neural network(IDRNN) was utilized to identify the fault intelligently after detecting the fault.Finally,the scheme,including fault detection based on the sliding-window Mallat wavelet and fault isolation based on the optimized IDRNN,was applied into a satellite attitude control simulation platform to verify the online diagnosis result.Experimental results show that the sliding-window Mallat wavelet fast transform is consistent with the classical wavelet transform in real-time scenarios,IDRNN has a better generalization ability for identifying time-variant signals,and the scheme including the sliding-window Mallat wavelet and IDRNN can implement detecting the faults and classifying the multiple faults based on real-time monitoring signals for the complex system.


There is a growing concern about environmental issues regarding industrial wastes coming from various industries, textile being one of them. The coloured effluents from textiles like dyes have become a serious concern as the removal is difficult and necessary. Taking this issue into consideration the adsorption studies of Methylene blue have been performed using Ni/Fe Layered double hydroxide also called as anionic clay. The Ni/Fe hydrotalcites were prepared by the co-precipitation method and used for the adsorption studies of Methylene blue. The effects like contact time and initial concentration of dye were investigated in the paper.


The utility model relates to a rotating pin interlocking device of a container hoist. The utility model comprises a rotating pin and a guiding sleeve sleeved outside the rotating pin, and also comprises a rotating handle which is arranged on the rotating pin and provided with a notch, a pin pushing device which can clip the notch of the rotating handle, a driving oil cylinder, and a limiting switch. A pin rod, a round clipping component, a returning spring, and a pin pushing nut are arranged on the pin pushing device. When the rotating pin interlocking device of the utility model is used to hang a container, the simple tension can be born, and the occurrence of the mistaken rotation can be avoided.


ABSTRACT The sexual behaviour of US youth places them at risk of negative outcomes such as sexually transmitted infections and unintended pregnancy. The US Centres for Disease Control recommend a positive and respectful approach to sexuality and relationships to improve these outcomes. Yet, sexuality education across the country, especially in the US South, remains insufficient. Peer sexuality education programmes are a method to improve knowledge and influence risky sexual behaviours. However, support for such programmes is often limited in higher education. Partnerships across different types of higher education institutions may enhance feasibility through resource sharing. This study analysed data from focus group discussions with faculty/staff and students (6 groups, n = 18 faculty/staff, n = 21 students) at three different higher education institutions in North Carolina. Participants provided perspectives on institution-specific facilitators and barriers to discussing sexual health on campus. Perceived facilitators and barriers were similar between the predominantly white institution and the historically Black college/university, while the community college presented unique logistical issues that should be considered when developing peer sexuality education programmes.


We have calculated the electrical conductivity in the current-in-plane geometry of multilayered granular alloys composed of Co clusters embedded in Ag alternating with pure Ag layers. In particular, we have paid attention to the conductivity behavior as a function of Ag layer thickness, Co clusters' size, and degree of percolation. The electronic structure is self-consistently calculated within the unrestricted Hartree–Fock approximation using a parametrized tight binding Hamiltonian which includes a Hubbard-like term. The conductivity tensor is obtained by using the semiclassical Boltzmann equation in the anisotropic relaxation time approximation. We have used a s−d Mott-like scattering model for the electronic mean free path taking into account the Sondheimer's picture for electronic transport in thin films. We find that the experimental conductivity behavior at coalescence can be explained through the electronic band contribution. The conductivity behavior of continuous multilayers is already attained ...


Navigation with a Phased Array Radio System (PARS) is prone to performance degradation due to radio wave reflections of the directed communication beam on reflective surfaces. This work presents a navigation algorithm, based on the Error State Kalman Filter (ESKF) and an outlier rejection scheme, to better handle such outliers, and thus improve navigation robustness. We show, with experimental data, that this algorithm results in an improved state estimation quality when radio beam reflections are present.


The 3,6-di-O-acetyl derivative 3 of the desulfated aglycone of pectinioside C, (20S,24S)-24-ethylthoransterol A (2), and its 24R and 24RS stereoisomers 4 and 27 have been synthesized stereoselectively from the pregnane derivative 3,6-di-O-acetyl-asterone (5). Herewith, the stereochemistry at the C-17 side chain of 2 and of pectinioside C (1) has been determined. (20S,24S)-3β-Acetoxy-24-ethyl-20-hydroxycholest-5-en-23-one (18), its 24R and 24RS stereoisomers 21 and 24, respectively, and some steroids with (20S)-20-hydroxy-24ζ-methyl-26-homo-25ζ-cholestane side chain have also been synthesized.


Summary Line C57 black mice has a mean of 6.3 Peyer's patches; strains C, Swiss, and dba, means from 8 to 9; and strain C3H, a mean of 10.7. Differences between these groups are significant, according to the X 2 test. There is a direct correlation between the number of Peyer's patches and the incidence of spontaneous mammary tumors in these 5 pure lines of mice.


It has recently been observed that the permanent of a non-negative matrix, i.e., of a matrix containing only non-negative real entries, can very well be approximated by solving a certain Bethe free energy minimization problem with the help of the sum-product algorithm. We call the resulting approximation of the permanent the Bethe permanent.


The increasing presence of solar energy sources has radically transformed the continental electrical network. While solar panels affect the grid in a distributed manner, and an individual device has negligible weight, the presence of a large population engaged in energy production can affect the overall network dynamics. While this effect might in some scenarios be disruptive, solar panels can offer the potential for frequency regulation, if their power output is to be controlled. In this work, we present models for the aggregation of a heterogeneous population of solar panels connected to the electrical grid. The electrical network frequency is modeled centrally: the model accounts for primary frequency control, and its inertia is a function of the penetration of PV generation. We study how features of the PV population affect the overall frequency signal. In particular, we investigate scenarios of power production (infeed) incidents: we simulate sudden generation losses and study the corresponding frequency response at varying levels of renewable penetration. Simulations show good performance of the aggregated models when compared with the physical system and quantitatively indicate that population heterogeneity is a desirable feature to avoid load shedding. We furthermore put forward a control architecture to regulate the power generation of the PV population: this intentionally simple architecture is aligned with primary control and is tailored to a decentralized implementation. We show that the control scheme can avoid load shedding, despite increasing penetration of solar generation, thus contributing to network resilience.


Introduction: The severe acute respiratory syndrome (SARS)-CoV2 is a viral respiratory disease threatening worldwide public health, social stability, and financial development. Pathological hallmark for SARS-CoV-2 is an ineffective innate immune reaction. i.e., immune cells recognize it as dangerous toxins in place of self-antigen. Published data on neutralizing antibodies suggests their role in the prevention and treatment of infection SARS-CoV-2 through passive immunity in COVID-19. Objective: The present paper discusses the role of vishghna dravya in either flushing out or neutralization of toxins from the body. Material & Method: We developed the screening system based on Ayurveda & Modern pharmacology from different databases. Reported plants and minerals were retrieved from ancient texts. Furthermore, pharmacology method was used to preliminarily uncover the molecule mechanism. Results: Nine herbs and five metallic bhasmas having Vishaghna property were systematically reviewed, out of which four herbs and five metallic bhasmas have been reported to possess neutralizing antibody potential. Vishagna dravya works on concept of Samana pratyarbdha, the inherent qualities of the predominant mahabhutas. Madhura rasa (six), Katu Rasa (Five), Tikta Rasa (seven), Kasaya Rasa (two) have Prithvi, Vayu, Akash & Agni Mahabhuta that may exert neutralizing effect by making the cells more strong, inhibits the absorption of virus & increasing the various metabolic activities. Conclusion: To meet this challenge, this article discusses some published Ayurveda herbs and Nano metals which may neutralize the virus toxin for the prevention and treatment of infection by SARS-CoV-2.


Summary Anti‐'Mia' is the most common alloantibody of potential clinical significance in the Taiwanese population. The Mi.III phenotype is rare among Caucasians but has a high incidence in various Oriental populations. We describe a nulliparous woman with no history of transfusions, who had hydrops foetalis at 28 weeks gestation. Foetal haemoglobin was 4·4 g dL−1, and a positive direct antiglobulin test was positive in the foetal blood. Intrauterine intravascular transfusion was given, and the baby was discharged healthy.


Top Runner is a Japanese programme addressing energy use in the transport, commercial and private sectors. Since the beginning of the programme in 1999, mandatory standards have been set for a variety of products. Th e programme is eff ective in the sense that, in general, the standards have been met. Th e appeal of the Top Runner approach is embedded in its clear and simple goal: go for the best; the product on the market with the highest energy effi ciency (the Top Runner) sets the standard. Moreover the scheme is dynamic: once the date is reached by which time the standard should be implemented, market data is analysed to select the next Top Runner. Review of the main characteristics of the Top Runner programme does not show insurmountable barriers for using the Top Runner approach in Europe. On the other hand it is unlikely that an exact copy of the Top Runner programme could be successfully implemented in Europe. Especially the fl eet average approach (i.e. not individual products but the sales weighted averages of products of a manufacturer have to meet the standard) does not seem appropriate for a mandatory instrument in Europe. Th e Top Runner approach can in principle be achieved in Europe by adopting specifi c implementing measures within the framework of the Ecodesign Directve. A separate "Top Runner" Directive is not needed. However, the Top Runner approach contains valuable lessons for the Ecodesign approach: Most important: make Ecodesign an appealing policy by focussing clearly on the minimum life-cycle costs: Ecodesign means lowest cost for the consumer. Make Ecodesign a dynamic policy by including an update clause in every specifi c implementing measure.


This paper considers the scientific and technological backgrounds of two quite different fields: petrochemical geophysics and information technology, and their respective and opposite roles in "shrinking" or "expanding" the perceived and actual size, scale, and grain of the developed landscape. The post-"oil peak" future will necessitate a contraction, or relocalization in the source-to-end use distances of physical goods and resources as transportation fuels become scarce and extremely expensive: for the first time in history, the world perceptually expands, as travel and freight shipping become more difficult and time-consuming. On the other hand, the continued increase in global electronic communication and consolidation of corporate ownership will continue to virtually "shrink" the world and globalize many aspects of culture. Thus, we enter a new perceptual relationship between time, scale, and sense of place unlike that ever previously experienced. As a result, we may anticipate future land patterns that respond to the relocalizing effects of scarce, expensive, and renewable transportation and shipping fuels on the one hand, and the continued globalization of culture and corporate ownership on the other.


We present a basic theorem in combinatorial geometry that leads to a family of approximation algorithms for the the geometric disk covering problem. These algorithms exhibit constant approximation factors, with a wide range of their choices. This flexibility allows to achieve a running time that compares favourably with those of existing procedures..


Natural resource area managers who restrict recreational access to control resource damage from recreation, can expect backlash responses from recreationists. The extent of support expressed by recreationists for land management policies that would restrict behavior while at a national park was measured using a survey instrument. Two variables—environmental attitudes and knowledge of damage to park natural resources by recreationists—were found to be positively related to support for both nonrestrictive and restrictive visitor management policies. Frequent users of the park were less likely to express support for restrictive policies that limited their use of the park. Implications for management are discussed.


ONE of the most important matters requiring investigation in the photodermatoses is the determination of action spectra. i,e., the identification ofthe wavelengths of " l ight" (ultra-violet, visible and infra-red radiation) that provoke changes in the skin. Snch information would be useful for two reasons. First, it would enable the clinician to choose an effective absorbing or reflecting apphcation for use on the skin, as the application must prevent tlie penetration of those wavelengths which specifically initiate symptoms. Second, knowledge of the action spectrum of a disease might lead to an understanding of its pathogenesis or even to identification of the photosensitising substance. This is because radiant energy is only " active " after absorption, so that if the active wavelengths are known, a search can he made among the substances which are known to absorb them.


The goal of this research was to evaluate the biodegradation of diesel by a microbial consortium collected in a region close to distributors of fuel. The experiments were monitored by SPME-GC-FID and SPME-GC-MS. The consortium showed a high potential for production of biosurfactants, presenting an emulsification index of 53%. The consortium degraded completely n-alkanes, while dimethylnaphtalene, hepthyl-cyclohexane and 2,6,10-trimethyl-undecane were partially degraded and pristane was not degraded. From this consortium five strains were isolated and identified as Acinetobacter baumannii. Based on this initial investigation this consortium appears to be effective for bioremediation in Porto Velho - RO region.


This research is a development of previous research entitled "Designing Regenerative Shock Absorber as a Vibration Energy Harvesting Tool on Vehicles" in the PUPT scheme funded by PNBP UNP 2017. In this study optimization of design oriented to energy generation was carried out while also paying attention to aspects driving comfort that might change due to the installation of a harvesting energy mechanism. One aspect of the change occurred in the type of magnet used, namely a ring type magnet with a type of neodymium material.From the test results obtained by changing the value of the efficiency of the shock absorber after the ERSA mechanism is installed by 2%, this condition also has an impact on the dissimilarity of the attenuation value obtained by 2% for the front-rear (left) and (right) wheels. In terms of generation voltage obtained the maximum generation voltage obtained is 25,600 mV. Based on the data obtained, it needs further development ERSA, especially in the aspect of the electromagnetic mechanism to optimize the generation of electrical energy.


Abstract The liquid crystal, 4′-cyano-4-biphenyl[4-(4-pentenyloxy)] benzoate (CBPB) has been chemically bonded to silica and the resulting material's interfacial properties examined by Fourier transform infrared spectroscopy. The spectral features of the nitrile stretching region for the chemically anchored system were significantly less complex than those obtained from samples of silica physically coated with CBPB. Further when CBPB was physically coated onto the chemically modified surface, its interactions with the substrate were reduced significantly.


The Digital Library of Wielkopolska (WBC) aims to respond to the need for regional repositories of local material. The WBC is a joint project of academic community of Poznan, in line with the spirit of Open Access, and like other regional Polish Digital Libraries, it uses dLibra software conceived and developed in the Poznan Supercomputing and Networking Centre. As of by now the following newspapers' titles have been published online: Dziennik Ostrowski 1936-1939, Oredownik na powiat wolsztynski 1921-1934, Gazeta Polska 1848-1850, Poznanskie ABC 1933, Dziennik Poranny 1935. The WBC is not using OCR presently, but manual indexing (keywords) has been applied for all books and some newspapers. Consequently, the WBC can be effectively searched by Google. The DjVu format is used for files uploaded to server, because of its good quality combined with small size, possibility for browsing page by page online, and possible advantages for OCR in the future. The Poznan University Horizon catalogue contains links to the WBC.
