As networks grow larger, network telemetry data collection becomes both more of a necessity as well as a challenge scaling with the extent of the network. In order to distribute network telemetry traffic among network telemetry collection endpoints, multiple layers of load balancing are used. Targeting the last layer—from the network interface to the collecting processes—we designed and implemented a system tailored to addressing practical challenges of running such a collection system while surpassing the existing system in both usability and performance.


ABSTRACT Analysing ancient art offers views into the visual worlds of its makers. The cusps and swirls typical of European Celtic Art have been interpreted as abstractions of faces and creatures inspired by earlier, more naturalistic art. Yet as 21st-century visual communicators used to 'reading' abstract emoji, we may be over-interpreting this aspect at the cost of other, still hidden dimensions. While humans share inalienable universals across space and culture, such as recognizing friendly or hostile faces, persons who lack facial recognition are diagnosed with autistic spectrum condition. However, their condition enables them to recognize embedded figures easily within crowded images or to focus on pattern instead of faces. My initial assessment indicates that some imagery of European Celtic Art would be compatible with an autistic idiom, similar as suggested for Palaeolithic art. This paper investigates these different ways of seeing European Celtic Art and opens new pathways for future research.


Objective:To investigate the relationship between serum leptin levels and obesity , blood pressure as well as serum uric acid in human bodies.Methods:Fasting serum leptin concentrations were measured with RIA in 150 subjects with normal glucose tolerance. The body mass index (BMI), waist circumference, hip circumference, waist to hip ratio(WHR), blood pressure and the fasting serum levels of blood glucose ,cholesterol, triglyceride, uric acid were determined sinmultaneously. Results:Serum leptin level was elevated in obese subjects, the step-wise multiple regression analysis showed that leptin levels were positively correlated with BMI, waist circumference, blood pressure and uric acid. Conclusions:There is leptin resistance in human obese subjects; leptin may play a part in the occurrence of hypertension and uric acid metabolism.


The interest and significance of the postwar municipal elections held in Britain can best be appreciated if they are seen against wartime conditions on the one hand and the reconstruction tasks which confront local authorities on the other. In England, as elsewhere, local government was designed to promote the arts of peace. But for six years during World War II it was asked to shoulder burdens of the most formidable kind directly connected with the war effort. The decision to make local authorities responsible, under the guidance of the Ministry of Home Security and its regional commissioners, for the complex of functions comprised under civil defense was a momentous one. Never before in Britain or any other country had local authorities been asked to undertake a task of such magnitude and importance as that of providing air-raid shelters, wardens and fire-guard posts in almost every street, gas decontamination centers, light and heavy rescue squads, evacuation schemes, emergency feeding and reception centers for those rendered homeless by enemy air attack, furniture stores, rest homes, a first-aid repair service for houses, and various other items of this kind. The Ministry of Food placed heavy duties on both local-government officers and councilors in connection with food control and rationing; and local authorities provided cheap restaurants and canteens on a large scale. The Ministry of Fuel and Power drew largely on the resources of municipal administration in appointing local fuel overseers and their staffs for regulating the distribution and consumption of solid and liquid fuel.

DESCRIPTION An 18yearold woman, with a congenital subaortic interventricular communication, was diagnosed with a 17week gestation. On the first echography, at that gestational age, a subaortic ventricular septal defect (VSD) with an overriding aorta (Ao) was identified (figure 1) associated with bilateral feet polydactyly. A foetal echocardiography, a couple weeks later, confirmed the defects previously mentioned and detected a pulmonary valve (PV) agenesis with a stenotic pulmonary ring, pulmonary free insufficiency and right ventricular (RV) predominance. These features were compatible with absent pulmonary valve syndrome (APVS) with Fallot's Tetralogy characteristics (TOFtype APVS), a rare cardiac outflow tract abnormality. APVS may be associated with chromosomal anomalies, and this relationship is more frequent with the TOFtype APVS. In the case described, amniocentesis was performed but no chromosomal or genetic variations, namely chromosome 22 microdeletion (22q11.2), were found. Nevertheless, given the poor prognosis, the patient requested pregnancy termination at 23 weeks gestation. The anatomopathological examination was concordant with the ultrasound findings. Despite increasing knowledge, prenatal diagnosis of APVS remains a challenge and a major step in parents counselling given its serious postnatal complications. 6 Globally, it is estimated that, absent PV syndrome affects 0.2%–0.4% of the newborns with congenital heart disease. Moreover, a higher frequency of congenital heart defects is known to occur in the offspring of parents who also have a congenital heart disease, namely atrioventricular defects. Pulmonary artery (PA) dilation on prenatal ultrasound may be a normal variation. However, its identification may also be present in isolated PV stenosis, ductus arteriosus constriction, situations of pulmonary hypertension or in TOFtype APVS. Differentiating features of TOFtype APVS include a massively dilated PA and its branches, left and right (5.8 mm, 6.4 mm and 4.2 mm, respectively, in this case) (figure 2A), a typical pattern of high velocities with colour aliasing between the right ventricle and the PA (figure 2B), a VSD, an overriding Ao and absence of ductus arteriosus. 6 The heart structure can be explored by the first trimester echography but mother characteristics (such as obesity), foetal position or physiological adaptations of the foetal heart inuterus may delay a definite diagnosis. Even an experienced sonographer may raise a suspicion of cardiac abnormalities only on the second or third trimester evaluation. Many times, the diagnosis happens just after birth.


ABSTRACT The notion of 'transition' as used to describe the recent drawdown of the decade-long Regional Assistance Mission to Solomon Islands (RAMSI) provides an obvious departure point for considering what other transformations – social, political and economic – are under way in the archipelagic nation. Yet the contributions to this special issue collectively reject the teleological language of transition and transformation deployed by many development actors in favour of a more nuanced and historically informed understanding of the central dialect between change and continuity, with change in Solomon Islands occurring slowly and in distinctly non-linear ways. This dialectic is traced and interrogated in various ways by the contributors to this issue. One broad theme concerns the contested narratives of changing state–society relations and, in particular, those between the central government and the rural localities where most Solomon Islanders continue to reside. Another is the changing social relations around land and natural resources engendered by ongoing processes of globalisation and persistent patterns of demographic change, migration and urbanisation. These and other processes of historical change, including state formation and capital accumulation, are also shaped by the enduring realities of scale and distance integral to Solomon Islands archipelagic geography. In this essay we explore these themes of change and continuity in Solomon Islands, positioning the individual contributions within this larger trajectory of slow-paced and distinctly non-linear change. Drawing heuristically on RAMSI's genesis in the state-building moment that dominated international relations during the first decade of this century, we also examine the distinction between 'state-building' and 'state formation' in the Solomon Islands context and, in doing so, contrast the tropes of state failure, weakness and fragility against narratives of resilience, tenacity, innovation and experimentation.


Cadmium is one of the most toxic metals causing growth inhibition as well as reduction of enzyme activity, photosynthesis, respiration, transpiration and nutrient uptake (Sanita di Toppi and Gabbrielli 1999). It can also induce oxidative stress by eliciting the generation of reactive oxygen species (ROS), which if not removed can damage cell structure and function (Prasad 2002). Contrary to cadmium, zinc is an essential micronutrient for plants, being involved in several cellular functions. Due to its role as a co-factor of enzymes it could have a stabilizing and protective effect against ROS-mediated oxidative and peroxidative damage (Aravind and Prasad 2005). Since cadmium is often associated with zinc as a contaminant it is important to investigate their interactions. Duckweed is very sensitive to cadmium, so in present study it was used to investigate the influence of zinc on cadmium toxicity. Duckweed (Lemna minor) was grown axenicaly on the modified Pirson-Seidel's nutrient solution (Pirson and Seidel 1950) supplemented with 10 µ ; ; M CdCl2, 100 µ ; ; M ZnSO4 or their combination. Growth was estimated during 14 days according to Ensley et al. (1994). The cadmium content was determined by atomic absorption spectrometry. Pigments were measured spectrophotometricaly (Lichtenthaler 1987). Maximum efficiency of photosystem II (Fv/Fm) was determined by measuring in vivo chlorophyll fluorescence (Schreiber et al. 1994). The level of lipid peroxidation was determined according to Heath and Packer (1968). Plant extracts were made in potassium phosphate buffer (pH 7.0) containing 1 mM EDTA, 5 mM ascorbate and PVPP for pyrogallol (Chance and Maehly 1955) and ascorbate peroxidase (Nakano and Asada 1981) as well as catalase activity determination (Aebi 1984). The growth of Cd-exposed Lemna plants progressively decreased during two weeks while the growth of Zn-exposed plants significantly decreased only at the end of experiment. Combination of Cd and Zn reduced growth significantly but reduction was not so prominent during second week of experiment like in Cd-exposed plants. Lemna minor accumulated high amounts of both metals (522 μ gCd/gDW and 2183 μ gZn/gDW). Zn replaced Cd to a certain degree since plants grown on medium with combination of Zn and Cd accumulated ~30% Cd less (356 μ gCd/gDW) and ~20% Zn (2589 μ gZn/gDW) more. The chlorophyll content decreased progressively during experiment and on 12th day it was 48% of control value on medium with Cd, 72% on medium with Zn and 47% on medium with their combination. Carotenoids content was significantly decreased only on 12th day (Cd 69%, Cd-Zn 70% and Zn 80% of control value). Fv/Fm decreased in all treatments but on 12th day the most prominent decrease was on medium with Zn. Cd induced lipid peoxidation, Zn not, but their combination diminished Cd effect on 12th day. In Cd-exposed plants, the activity of antioxidative enzymes significantly increased while Zn did not change but even decreased it. In plants grown on medium with both metals, the activity of catalase and ascorbate peroxidase was more similar to control values especially on 12th day while the activity of pyrogallol peroxidase increased. In conclusion, Zn alleviated Cd-induced growth reduction as well as Cd accumulation in duckweed. Among oxidative stress parameters only catalase activity suggests that Zn could diminish Cd-induced ROS formation. Since Zn alone affected both, pigments content and PSII efficiency chosen concentration of Zn (100 µ ; ; M) was probably too high. References: Aebi H. (1984). Methods in Enzimology 105, 121-126.

One of the most intriguing passages in any of D.C. Scott's Indian poems occurs near the end of "At Gull Lake: August, 1810." In the passage, Keejigo, the half-breed protagonist of the poem, goes through a process of alchemical transmutation, as suggested by Scott's description of the rainbow that forms after her death. Thus, a full understanding of Scott's poem depends on the recognition that in the poem's conclusion Scott draws upon the alchemical notion of a close correspondence, almost an identity, between the transmutation of metals and spiritual purification and regeneration. As well, it can be argued that in a small amount of Scott's work there is the presence of various images and ideas which are evocative of hermeticism and that the poet may have been acquainted with the hermetical writings of such writers as Henry and Thomas Vaughan.


As a part of the architecture of the Israeli occupation of the Palestinian Ter- ritories, the Israeli government introduced in 2005 a series of so-called terminal check-points as "neutral border crossings", to minimise the impact of these barriers on Palestinian lives through a different design and the use of several machines, such as turnstiles and metal detectors. In this article, we analyse terminal Checkpoint 300 in Bethlehem, framing it as a spatial political technology aimed at controlling the movement of Palestinians. More specifically, we investigate the interactions between Palestinian commuters, Israeli oldiers/security guards and the machines operating inside Checkpoint 300. We conclude by suggesting that Checkpoint 300 is a porous barrier whose regime is produced, reproduced but also challenged by such interactions, and that, despite the new "neutral design", Checkpoint 300 is a place still filled with tension and violence, often exercised by the machines and their "decisions".


BACKGROUND
The few identified leptin-deficient children have immune deficiency.

AIMS
To evaluate whether a newly-identified leptin-deficient boy has immune defects; to assess the immune changes during leptin replacement.

METHODS
A 5 year-old boy with congenital leptin deficiency was evaluated before, 2 weeks and 6 weeks after the initiation of recombinant methionyl human leptin. Thymic volume was measured by computed tomography. Humoral immunity was assessed by measuring levels of several immunoglobulins. Cellular immunity was evaluated by the analysis of lymphocyte proliferation in response to mitogens. Lymphocyte subsets were quantified by flow cytometry.

RESULTS
At baseline, thymic volume was increased. The lymphocyte subsets count and humoral/cellular immunities were normal. After treatment, proliferative response to mitogens increased by 1.5- to 3-fold, and lymphocyte count decreased by 17%.

CONCLUSIONS
Immune defects are not an obligatory feature of congenital leptin deficiency. Even in the absence of significant immune defects, leptin replacement therapy enhanced T-cell responsiveness.


BACKGROUND
Controversy exists as to whether low-dose cabergoline is associated with clinically significant valvulopathy. Few studies examine hard cardiac end-point data, most relying on echocardiographic findings.

OBJECTIVES
To determine the prevalence of valve surgery or heart failure in patients taking cabergoline for prolactinoma against a matched non-exposed population.

DESIGN
Population-based cohort study based on NE London primary care records.

METHODS
Data were drawn from ~1.5 million patients' primary care records. We identified 646 patients taking cabergoline for >6 months for prolactinoma. These were matched to up to 5 age, gender, ethnicity, location, diabetes, hypertension, IHD and smoking status controls. Cumulative doses/durations of treatment were calculated. Cardiac endpoints were defined as cardiac valve surgery or heart failure diagnosis (either diagnostic code or prescription code for associated medications).

RESULTS
18 (2.8%) cabergoline treated patients and 62 (2.33%) controls reached a cardiac endpoint. Median cumulative cabergoline dose was 56mg (IQR 27-123). Median treatment duration was 27 months (IQR 15-46). Median weekly dose was 2.1mg. Neither univariate nor multivariate analysis demonstrated a significant association between cabergoline treatment at any cumulative dosage/duration and an increased incidence of cardiac endpoints. In a matched analysis the relative risk (RR) for cardiac complications in the cabergoline-treated group was 0.78 (95% CI 0.41-1.48; p=0.446). Re-analysis of echocardiograms for 6/18 affected cabergoline treated patients showed no evidence of ergot-derived drug valvulopathy.

CONCLUSIONS
The data did not support an association between clinically significant valvulopathy and low-dose cabergoline treatment; and provide further evidence for a reduction in frequency of surveillance echocardiography.


PLS(Pohang Light Source) will begin the PLS-Ⅱ project that has been funded by the KOREA Government in order to further upgrade the PLS which has operated since 1992. The control system of the PLS-II has distributed control architecture, with two layers of hierarchy; operator interface computer (OIC) layer and machine interface computer (MIC) layer. The OIC layer is based on SUN workstation with UNIX. A number of PC-based consoles allow to remotely operating the machine from the control room. PC-based consoles use the Linux or Windows operation system. Similar consoles in the experimental hall are used to control experiments. The MIC layer is directly interfaced to individual machine devices for low-level data acquisition and control. MIC layer is based on VMEbus standard with vxWorks real-time operating system. Executable application software modules are downloaded from host computers at the system start-up time. The MIC's and host computers are linked through Ethernet network. It should enable the use of hardware and software already developed for specific light source requirements. The core of the EPICS (Experimental Physics and Industrial Control System)[1] has been chosen as the basis for the control system software.


The objective of this research was to find a more effective method for the teaching of history to Chinese students studying in South Korean universities. Questionnaire surveys and interviews were conducted to investigate those students' level of knowledge and perceptions of Korean history. Then, in history classes, four teaching methods (comparative-historical, audiovisual, history and language, and rote memorization) were applied over two weeks. Before the treatment, Chinese students said that they liked the audiovisual teaching method the most, but after taking the classes, they preferred the teaching method comparing Korean and Chinese histories. Besides the finding that the comparative method was the most popular, the responses also showed that it was the most effective one in teaching history to Chinese students.


This and the companion paper(1) deal with space-dependent boiling water reactor kinetics by the method of adiabatic approximation. In this paper, equations are derived for axially space-dependent BWR feedback kinetics. These equations are coupled to the neutron equations through adiabatic approximation. The reactor is divided into a number of axial regions. Assuming a trapezoidal distribution of the void and the water velocity distributions along the axis, balance equations for energy and mass are integrated to yield the region-exit quantities. With other pertinent equations, a computer code is written. Some numerical results for a sample BWR are presented in the companion paper.


The aim of this ethnozoological study was to identify variables related to knowledge, perceptions, and practices associated with the occurrence of bats in an urban area. We carried a retrospective observational study with residents of 31 cases and 178 control households. We defined the cases as households where accidents occurred from 2012 to 2015, according to official health records. The control households have no accident record in the same area. We conducted data collection through a semi-structured questionnaire and performed descriptive analyses and proportion (chi-square) to identify differences between the responses of cases and controls. We have identified important gaps in relation to basic knowledge, good practices, and the importance of bats to public health. These findings should be targeted for intervention and correction by environmental educators and health managers aimed at reducing the risk of accidents with bats and zoonosis, mainly rabies.

Nowadays building material industry as well as other industry branches exercise bigger demand to use powders with high dispersion. Jet mills are used to produce such powders that is why development of new jet mill designs, increase of grind efficiency, reduction of specific energy consumption is an important objective. This article provides a mathematic description of the two-phase flow motion at the outlet of the vertical acceleration tube of a jet mill with a plane grinding chamber of torus shape. The part of the acceleration tube above the impact plate is essential for grinding, as the initial particle grind occurs at this very section, in the grind chamber. Moreover, the initial grind defines the size of particles, that are further reground at the mill chamber. As a result of theoretical calculations, a formula is obtained that allows to determine the height of the acceleration tube from the bump element at the specified speed parameters of the two-phase flow. The article also contains the graph, that shows how particle velocity depends on the current (specific) height point (value) of the acceleration tube. This graph demonstrates that particle size strongly affects the way they move in the grind chamber. The formula allows to calculate the effective propulsion range of particles, depending on theirs' size, by presuming they have the maximum velocity


The wide use of passive voice is a very important syntactic feature of English for science and technology and its translation is quite flexible. This paper discusses the occasions where passive voice is widely employed,introduces several frequently used translating methods,and points out that various translating methods must be adopted to ensure that the transferred texts suit the Chinese language's expressing habits and are readable in the Chinese context while keeping the accuracy of the transferred information.


Background: Globally, women constitute 49.6% of the world population and at least 500 million women and girls lack adequate facilities for menstrual hygiene management. In Nigeria, a quarter of women lack adequate privacy for defecation and menstrual hygiene management. Absence of facilities needed for menstrual hygiene can pose as obstacle to women and girls practicing menstrual hygiene effectively. This study aims to identify the facilities and misconceptions concerning menstrual health and menstrual hygiene management. Methods: This was a descriptive cross-sectional study among 169 young males and females of Evangelical Church Winning All (ECWA) Theological Seminary, Jos North, Plateau State. This study sought to identify the facilities and misconceptions concerning menstrual health and menstrual hygiene management among young people in Jos, Plateau State. Nigeria. Simple random sampling technique was used in this study and data was collected using interviewer-administered structured questionnaire to measure availability of facilities/programs for menstrual hygiene management and misconceptions about menstruation. Data analysis was done using the Statistical Package for the Social Science (SPSS) version 20.0 with descriptive statistics, proportions, tables and diagrams used to illustrate findings from the data collected. Results: Majority 139 (82.2%) of the female respondents had access to adequate water supply, while 30 (17.8%) did not have access to the adequate

Politeness is basically the speaker's way of communicating so that the speech partner does not feel pressured, cornered, or offended. Communication is a process that occurs in social life. At this time, almost all Indonesian people use social media and the biggest user is YouTube social media. Youtube is a social media that is watched by all people and all ages. Youtube contains various types of content, one of which is Boy William's YouTube channel entitled Boy William's National Examination (UNBW). This series discusses Youtube content for Boy William's National Examination (UNBW) with actresses Ayu Ting-Ting and Anwar. Politeness in language on Youtube social media functions to fence off Youtube users as polite loudspeakers. Conversations during UNBW will be the object of language politeness analysis with a review based on Leech's theory. The politeness theory put forward by Leech (1983: 132) is known as maxims which describe the realization of linguistic politeness, and further elaborates the linguistic politeness strategy into 6 maxims namely: 1) tact maxim, 2) generosity maxim , 3) approbation maxim, 4) modesty maxim, 5) agreement maxim, and 6) sympathy maxim. After reviewing the data, I pointed out that the conversation on UNBW's Youtube content for the Ayu vs Anwar series contains language that is impolite for other people to watch but is still considered polite if this conversation is only for Boy William, Ayu Ting-Ting, and just Anwar.


Angiomyolipoma (AML) is a rare benign tumor composed of adipose tissue, smooth muscles and blood vessels with an incidence is 0.3-3% which is predominantly found in females. These tumors have a strong association with tuberous sclerosis but can occur sporadically. Clinical importance lies in their susceptibility to spontaneous haemorrhage. They can be unilateral or bilateral. Interestingly these tumors occur more in right kidney. We present a case of sporadic unilateral angiomyolipoma of left kidney in a 55 yrs old female who had complaints of off and on left lumbar pain. She was subjected to left nephrectomy and diagnosis was confirmed on histopathology. Key Words Angiomyolipoma(AML), kidney tumour, renal angiomyolipoma.

In this study, we present a tunable metamaterial consisting of rotatable non-uniform Mie resonators (NMRs) with identical structures. The metamaterial can in real-time manipulate the direction of acoustic radiation and guarantee high transmission efficiency by simply changing the rotation angle of the NMR unit cells, which is induced by the anisotropic property of NMR. In addition, according to generalized Snell's law, the arbitrarily direction-scanning capability is realized by tuning the phase shift distribution along the metamaterial. Our proposed anisotropic metamaterial could contribute to designing a device for the emission and reception of acoustic waves in real-time.


I have read the Rubin-Feeley article, Federalism And Interpretation, with pleasure and profit. I love their robust conclusion with its thumping disdain for federalism, that pitiful enterprise, an "incomplete state," prone to self-destruction?unless it can somehow transform itself into a unitary regime, like the good, old USA. So, while I strongly disagree with certain crucial points in their analysis, I wish to emphasize that the merits of the essay justify and encourage more of their kind of thinking about federalism. The title of the book on which the article is based, Federalism: Political Identity and Tragic Compromise, summarizes their argument. Certain features of a federal system, they contend, gravely weaken, and may well destroy it. They feel that we students of federalism are not taking our subject seriously enough to see this inherent frailty. We do not get to the heart of the matter. Our thoughts lack "real federal theory/' a failing they propose to remedy. My criticism may be set right by the longer text of the book. Be that as it may, the intellectual stimulus which I have experienced by attempting this critique testifies at any rate in my opinion to the merit of their work. They propose to raise the level of our understanding of federalism by examining this type of structure from the viewpoint of two familiar perspectives of social science, positivism and interpretivism. I heartily approve of this procedure. It is an ingenious analytic device, illuminating facts and posing important questions. The two methods of inquiry reveal different aspects of human activity. The positivist conducts his inquiry by external observation in the manner of physics, chemistry, biology, and other natural sciences. "Positivist social science," write Rubin and Feeley, "...begins from the base-level assumption that human beings... have an identifiable internal structure that governs their response to identifiable external forces. Both the internal structure of human beings and the forces that act upon them can be discerned by an external observer, that is, through the techniques of empirical observation." In contrast, "interpretive social science begins from the base-level assumption that human action is primarily determined by an internal process that exists within the mind of each person and is not fully accessible to external

A direct neural interface system (NIS) promises to provide communication and independence to persons with paralysis by harnessing intact motor cortical signals to enable controlling prosthetic devices. An intracortical NIS aims to achieve this by sensing extracellular neuronal signals through chronically implanted microelectrodes and by decoding the spiking activity of neurons into prosthetic control signals. In non-human primate studies, decoding has been performed by finding a relationship between neuronal signals and actual limb movements. However, such decoding approaches face challenges in the case of paralyzed persons where there is no true movement information. Specifically, we have focused on dealing with several key questions in decoding of neural activity in humans with paralysis: what movement parameters should be decoded?; which decoding algorithms lead to more accurate estimation of movement parameters?; how do we train decoding algorithms without observing actual movement parameters?; and how many control parameters can be decoded from a single neural ensemble? In this paper, we summarize our recent studies to address these questions to improve decoding performance, which enables a human with tetraplegia to drive a 2D computer cursor to an arbitrary position and execute a "click" on the area of interest.

The aim of this study was to evaluate the quality of life among hypertensive patients attending governmental and UNRWA clinics. It used a descriptive analytical cross sectional design, the study sample included 340 subjects aged between 40 – 71 years old, and who had hypertension at least for two years. Two settings were chosen randomly one belong to the government and the other belong to UNRWA. Subjects were recruited by using non probability convenient sample method, 170 subjects from each setting comprising 85 males and 85 females. Subjects were told to sign consent in order to participate in the study. A face to face structured interview was used to collect data from the participants by using demographic information sheet and the WHOQOL – BREEF questionnaire. Results of the study revealed that, the percentage of the total scores of the QOL among the whole study sample 65.63%, the highest domain was the social at (70.14%), and the lowest one was the environmental at (62.40%). Demographic characteristics including, age, sex, marital status, educational attainment, duration of disease, monthly income, family size, working status and clinic being visited, was statistically significant except for some domains pertaining to some groups. Physical, psychological and social domains were lower in the group of monthly income 3000NIS and above in comparison with the group of monthly income 2001 – 3000NIS at level of significance (f = 12.51, 15.85, 13.61) respectively. In regard to marital status psychological and social domains were higher in the married group in comparison with divorced group, but the physicals domain in the divorced group was better than that in the married group at level of significance (f = 19.55, 18.22, 24.22) respectively. Family size and clinic being visited, showed no statistical significance, except for the social domain in favor of subjects visiting the governmental clinic, statistical significance at (t =2.19; df =338; p<0.05). As a matter of fact, health care providers and decision makers should consider the results of this study to contribute in the promotion of health care services provided to hypertensive patients to reduce their suffering, prevent and delay future complications as well as helping them to have and enjoy a better quality of life.


— A study was undertaken to determine the number and distribution of diastemas within the dentitions of three racial groups of man, (a diastema being defined as a space greater than 0.5 mm between the proximal surfaces of adjacent teeth). From examination of the dentitions of 656 subjects, the mean number of diastemas was found to be 2.07 for Caucasoids, 2.09 for mongoloids, and 2.02 for negroids. In all three population samples, 75 % of the diastemas occurred in the maxillary dentition and 25 % in the mandibular dentition, the diastemas being mainly confined to the region of the dental arch anterior to the first premolar.


In IoT, a flexible and trustworthy access control framework is of significance to ensure the security of lightweight IoT devices. The conventional centralized access control framework is no longer fit for the open and large-scale IoT environments. In this paper, we propose an attribute-based distributed access control framework (ADAC) for IoT using blockchain technology. The attributes, such as manufacturer and object-specified attribute, are considered in the proposed ADAC for more fine-grained access control in the open and lightweight IoT devices. Particularly, we design a smart contract system, which includes a subject contract (SC), an object contract (OC), an access control contract (ACC) and multiple policy contracts (PCs), to manage and access attributes of IoT devices for distributed and trustworthy access control (DTAC). SC and OC are responsible for managing subject attribute and object attribute information, respectively. PCs are used to manage access control policies. ACC performs authorization judgment by accessing attributes and policies. Finally, a case study is performed to demonstrate the workflow and show that ADAC could achieve fine-grained and flexible access control for IoT.

Medical nutrition therapy includes nutrition screening, referral, assessment, and intervention. The document includes sections on client rights, dietitian referral, and benefits of therapy. Contact information to obtain the document and information on medical nutrition therapy are provided.


Now the logistics of China is still placed in the early class stages.There are many confinements existing such as the system and the technique level that operate in the enterprise,but now the researches of the TPL enterprise selection are all limited to qualitative analysis.This text uses the fuzzy comprehensive appraisal method with quantitative analysis to choose the TPL enterprises scientifically for enterprises.


Attribution in cyberspace is one of the most difficult questions facing policy makers, lawyers, and jurists. Indeed, the first question often asked in the wake of a cyber incident is "who did it?" The answer to this question is often critical when dealing with the application of international law because it will dictate the rights and responsibilities of States both from an offensive and defensive perspective. Without proper attribution, for example, a State's responsive capabilities are limited. Making matters worse, attribution is difficult to establish factually. Non-State actors often mask their identity, and State actors often hide their true intentions. The degree to which the international rules governing State attribution apply in cyberspace is therefore a matter of great public importance.


Reaction of some wild oat (Avena fatua L. ♯4 AVEFA) populations to the herbicide triallate [S-(2,3,3-trichloroallyl)diisopropylthiocarbamate] was investigated in a controlled-environment chamber. Under specified conditions, 1.0 mg active ingredient of triallate incorporated in 1 kg of soil was a satisfactory diagnostic rate for 14-day-old seedlings. Five seedling growth parameters were studied. These parameters were emergence, survival to produce first leaf, mesocotyl length, first-leaf length, and seedling height. Of these, mesocotyl length was least affected by triallate treatment, and significant differences in variability for triallate reaction were found within and among historically triallate unexposed, as well as exposed populations. Within-population variation for seedling emergence and survival was higher in unexposed than in exposed populations. Populations with recurrent exposure to triallate were more tolerant to the herbicide under experimental conditions than historically unexposed populations. Triallate-tolerant lines were identified which were tolerant to two other common wild oat herbicides.


Porphyrins represent one of the oldest, most widely studied chemical structures, both in nature and in biomedical applications. Due to their tumor avidity and favorable photophysical properties, such as long wavelength absorption and emission, easy derivatization, high singlet oxygen quantum yield and low in vivo toxicity, porphyrins have found particular success for photodynamic therapy and fluorescence imaging of cancer. Additionally, they are excellent metal chelators, forming highly stable metallocomplexes, making porphyrins an efficient delivery vehicle for radioisotopes. Thus, there is great potential in the applications of these multi-modal porphyrin-based agents for cancer imaging and therapy. I have investigated the characteristics of various porphyrinbased probes and their potential application in different clinically relevant models. Here, I will discuss three types of porphyrin-based agents: 1) photodynamic molecular beacons (PPMMPB), 2) targeted peptide porphyrins (PPF) and 3) porphyrin-lipid nanovesicles, porphysomes. I will demonstrate that all of these porphyrin-based agents have potential clinical applications in various fields of cancer imaging and therapy. Although these three


Objective To detect the plasma metabonomic profile of rats subjected to hemorrhagic shock (HS) by using 1H-NMR analyzer.Method Ten male Wistar rats were randomly divided into an HS group and a control group, with 5 rats in each group. Plasma of rats was collected and its 1H-NMR spectra were acquired.Results The differences in plasma metabonomic profiles were identified between the two groups after the data were processed by principal components analysis (PCA). The remarkable differences in plasma metabonomic profile between two groups were in lactate and lipids,such as very low density lipoprotein (VLDL), low density lipoprotein (LDL) and unsaturated fatty acid.Conclusion 1H-NMR analysis is a promising technology for the detection of the variation of plasma metabonomics of rats subjected to HS.


Interactions between membrane proteins (MPs) and lipid bilayers are critical for many cellular functions. In the Rosetta molecular modeling suite, the implicit membrane energy function is based on a "slab" model, which represent the membrane as a flat bilayer. However, in nature membranes often have a curvature that is important for function and/or stability. Even more prevalent, in structural biology research MPs are reconstituted in model membrane systems such as micelles, bicelles, nanodiscs, or liposomes. Thus, we have modified the existing membrane energy potentials within the RosettaMP framework to allow users to model MPs in different membrane geometries. We show that these modifications can be utilized in core applications within Rosetta such as structure refinement, protein-protein docking, and protein design. For MPs structures found in curved membranes, refining these structures in curved, implicit membranes produces higher quality models with structures closer to experimentally determined structures. For MP systems embedded in multiple membranes, representing both membranes results in more favorable scores compared to only representing one of the membranes. Modeling MPs in geometries mimicking the membrane model system used in structure determination can improve model quality and model discrimination.


The hydraulic study of drinking water is one of the things that must be done in order to obtain a realistic perception of the network's functioning and the problems it suffers from, As well as to reach the scientific method to expand it if required, knowing that the population density is constantly increasing, as is the urban expansion, The aim of this study is evaluated and analyzed al-karada water distribution network to determine the areas of pure water scarcity and its causes, and the study relied on the data of the Baghdad water supply administration for the year 2020 and its divisions, where a hydraulic model of the network was created for the purpose of analysis, it included a review of the pressures and speeds during the average daily demand per person of 350 liters / day and during the maximum operational design capacities of the compacts Units, the results showed that the pressures within the acceptable limits and the flow velocity are not excessive in some pipe due to the low average daily demand.


The decisions of financial investors are often made in real-time under many constrains in an environment containing vague and imprecise information. The great amount of financial data brings additional problems in the decision making process. Currently, there are various and diverse software systems to support this process, some based on fundamental analysis and others - on technical analysis. Fuzzy rule-based systems provide the tools to overcome the above difficulties to some extent, due to the fact that dynamic models of complex and non-deterministic systems with unstable and uncertain parameters can be relatively easily. However, fuzzy systems have a serious disadvantage and it is the lack of flexibility. In this work, a hybrid genetic fuzzy system for managing financial assets and test results are presented.


This study examines the shipping demand of firms in Hsinchu Science Based Industrial Park in Taiwan for using air cargo logistics services and explores what are the important factors for decision-making on selecting the logistics company. Firm's perceptions toward different services are investigated by designing and conducting a questionnaire survey. The study then evaluates the differences in services among different industries utilizing Distribution-Free Statistics and analyzes the correlation between services using Correlation Analysis. A logit model is further formulated to determine firms' choices between different types of logistics companies. The results show that the most important service attribute is safety, followed by confidentiality, total shipping time, accurate delivery time, and accurate delivery place. Firms in the well-developed industries emphasize more on the size of the logistics company while place less weight on value-added services as compared with those in low-developed industries. The results of calibrated utility function also show that high-tech firms with high-value products place less weight on charges, while more weights on total shipping time and door-to-door service.


A study of village revenue and village expenditure in the development sector is needed to analyze the effect on villages in Lahat District. Secondary data are in the form of APBDes Realization Reports from the Community and Village Empowerment Service. Village revenue affects village expenditure in development. Village fund (DD) and village fund allocation (ADD) have a significant effect on the positive direction of village expenditure in the development sector. In Lahat Regency, the majority of villages use transfer funds to be allocated to village expenditure in the development sector. Because the small amount of village original revenue (PADes) is not possible to be allocated to village expenditure in the development sector, tax and retribution results section (BHPR) is due to overlapping of central and regional regulations.

Relaxed memory consistency models tolerate increased memory access latency in both hardware and software distributed shared memory systems. In recoverable systems, relaxing consistency has the added benefit of reducing the number of checkpoints needed to avoid rollback propagation. The authors introduce new checkpointing algorithms that take advantage of relaxed consistency to reduce the performance overhead of checkpointing. They also introduce a scheme based on lazy relaxed consistency that reduces both checkpointing overhead and the overhead of avoiding error propagation in systems with error latency. They use multiprocessor address traces to evaluate the relaxed consistency approach to checkpointing with distributed shared memory.


Objective To explore the effect of improved double Endobutton plate in the treatment of complete acromioclavicular joint dislocation.Methods 30 cases of patients with complete acromioclavicular joint dislocation were selected and divided into the observation group(15 cases) and the control group(15 cases).The observation group were treated with improved double Endobutton plate,the control group were treated with classical technique of double Endobutton plate,the operation time and postoperative recovery was compared between two groups. Results The average operation time of the observation group decreased significantly compared to the control group,the difference was significant(P0.05).Constant score before and after treatment of two groups had significant difference( P0.05),but the two groups had no significant difference(P0.05).Conclusion Improved double Endobutton plate for the treatment of complete acromioclavicular joint dislocation can reduce the operation time,and is worthy of clinical promotion.


We investigate the appearance of π lapses in the transmission phase θ of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization group methods we study the entire parameter space for spin-polarized as well as spin-degenerate dots, modelled by spinless or spinful electrons, respectively. We investigate the effect of finite temperatures T. For small T and sufficiently small single-particle spacings δ of the dot levels we find π phase lapses between two transmission peaks in an overwhelming part of the parameter space of the level-lead couplings. For large δ the appearance or not of a phase lapse between resonances depends on the relative sign of the level-lead couplings in analogy to the U = 0 case. We show that this generic scenario is the same for spin-polarized and spin-degenerate dots. We emphasize that in contrast to dots with more levels, for a two-level dot with small δ and generic dot-lead couplings (that is up to cases with special symmetry) the 'universal' phase lapse behaviour is already established at U = 0. The most important effect of the Coulomb interaction is to increase the separation of the transmission resonances. The relation of the appearance of phase lapses to the inversion of the population of the dot levels is discussed. For the spin-polarized case and low temperatures we compare our results to recent mean-field studies. For small δ correlations are found to strongly alter the mean-field picture.


A fundamental challenge for robotic target-tracking systems is to cope with cases in which the target is not seen for long periods of time. An additional challenge in multiple-robot systems is to coordinate robot activity to best track targets with limited visibility. We describe a novel technique that combines a particle filter target model with a potential field robot controller. Robots are attracted to points sampled from the particle cloud that models the probability distribution over the target's position, subject to environmental constraints. We show how this method can be used as a coordination strategy whereby a team of robots cooperatively minimize the uncertainty in the pose of a tracked target. Simulation results are presented


The purpose of this study is to develop a new preparation process of American ginseng (Panax quinquefolium) extract featuring high concentration of ginsenoside Rg3, Rg5, and Rk1, Red ginseng special components. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of American ginseng were processed under several treatment conditions of microwave and vinegar (about 14% acidity). The results showed that the quantity of ginsenoside Rg3 increased by over 0.9% at the 20 minutes of the pH 2~4 vinegar and microwave American ginseng ethanol extract compared with other process times. The result of MAG-20 indicates that the American ginseng microwave and vinegar-processed American ginseng extracts (about 14% acidity) treated for 20 minutes produced the highest amount of ginsenoside Rg3 (0.969%), Rg5 (1.071%), and Rk1 (0.247%). Besides, MAG-15 indicates that the microwave - and vinegar processed American ginseng extracts (about 14% acidity) treated for 15 minutes produced the highest amount of ginsenoside Rg3 (0.772%), Rg5 (1.330%), and Rk1 (0.386%). This indicates that American ginseng treated with microwave and vinegar had the quantity of the ginsenoside Rg3 over 32 times the amount of the ginsenoside Rg3 (which was not found in raw and American ginsengs) in the average commercial Red ginseng.


Previous studies have shown that physical community layout is associated with mobility in older adults and that balance confidence (BC) improves their life-space mobility. However, few studies have examined how BC, physical residential characteristics have an impact on the proximity of distance. The purpose of this study was to assess the relationships BC, physical accessibility and life-space mobility. A cross-sectional design was used with a convenient sample of 90 older adults living in an independent facility in an urban city in Michigan. Eligibility criteria included understanding and speaking English and being medically stable. Measures were Life-Space Assessment (LSA), Short Version of Activity-specific Balance Scale (ABC-6) and the Housing Enabler Assessment and Modifications. ANCOV As were performed using SPSSv22. The mean age of the participants was 66.83 years old, ranging from 50 to 93 years. The majority was African American (76%), single (94%), female (67%), and received a GED or completed some high school (54%). The results show that older adults with a high BC had a greater LSA after controlling for age, gender, race, and marital status (p<0.001). Residential accessibility was not associated with LSA, however it was associated with BC (p<0.05). African Americans with lower education attainment had a greater LSA oflevel 3 compared to Caucasians (p< 0.019). Males (p< 0.007) and older adults with high education attainment (p< 0.020) had significantly higher BC. Complexity was detected in these interrelationships. BC, race and gender must be considered to improve life-space mobility among

Affected by the reservoir heterogeneity and other factors,artificial fracture orientation may deviate from the direction of well patterns,which are placed along favorable orientation,and the integral fracturing effect will be affected. So,taking rhomboid anti- nine spot pattern in Chang 6 reservoir of Baibao oilfield as an example,a numerical simulation model of integral fracturing with deflected fracture was established,the integral fracturing parameters were optimized and the influence of different fracture parameters on production performance was studied. Results showed that when the fracture orientation deflected,the recovery degree was reduced greatly,especially,when the fracture orientation deflects with a slight angle,the recovery degree was reduced to a great extent. In this case,adjusting local well pattern or reducing the fracture length was suggested.


After conducting our first research project as academic librarians, we realized we had taken some missteps and would have benefited from a primer that walked us through the basics. When administering our first survey, we discovered that an ample amount of forethought, planning, and investigation is essential. This article evaluates our first foray into research and provides accessible tips and guidelines for our colleagues.


The early universe is characterized by a model based on three hypothesis: homogeneity and isotropy, ordinary matter and standard gravity. But, in this way, we obtain predictions that are in conflict with observations because they cannot explain the late time expansion of the universe. Then at least one of the three assumptions must be wrong. According to ΛCDM, the agreement with data is restored by introducing a new term in the Einstein equation. Depending on which side of the Einstein equation this term is put in, we have two possibilities: to modify gravity or assume the existence of dark energy. However, a valid alternative is provided by constructing models in which inhomogeneities and/or anisotropies are present. The effect of inhomogeneities/anisotropies on the expansion of the universe is referred to as backreaction. For this reason, we study inhomogeneous and anisotropic Szekeres models and spatially homogeneous but anisotropic Bianchi universes. In this work we start by introducing the covariant formalism. Then we describe the averaging procedure in the framework of Buchert's approach (considering only the dust case) and we obtain the Buchert equations, from which we can define the backreaction variable. Finally we study dust solutions of the Einstein field equation. First we analyze the Szekeres metric, then we pass to the Bianchi models. In a recent work by M. Lavinto, S. Räsänen and S.J. Szybka the Szekeres metric has been used to construct a Swiss Cheese dust model with Szekeres holes and to prove that, under certain assumption, this model can provide a large backreaction, i.e. inhomogeneity has a significant effect on the average expansion rate of the universe.


This chapter examines the relevance of the economic vulnerability concept for low-income countries (LICs), a topic which has recently been given considerable importance by several international bodies. Reference is also made to the vulnerability of small island developing states. Conceptual aspects of vulnerability are first discussed. It is argued that an indicator of structural economic vulnerability across LI Cs can be constructed with three main components namely (1) natural shocks proxied by instability in agricultural production (2) trade shocks, proxied by instability ofreal exports and (3) structural exposure to these shocks, proxied by the size of the population. Other possible components are also examined. Special reference is made to the economic vulnerability index, constructed by the UN Committee for Development Policy (CDP-EVI). The chapter argues that structural vulnerability is a matter of concern for growth, factor productivity and co-operation policies. 1. Recent Interest in Economic Vulnerability The economic vulnerability of developing countries is not really a new concept, but it has recently been given considerable attention, mainly because of the interest of several international organisations. There are two important and, to some extent interrelated, concerns, in this regard, namely (1) the concern of the UN to consider vulnerability in the process of identification of the LDCs and (2) the concern of the small island developing states (SIDS) to be recognised as more vulnerable than other groups of countries. The UN concern was first expressed in connection with the revision of the LDCs' identification criteria in 1991, and this led eventually to the adoption of an economic vulnerability index as a criterion for identification in 1999-2000. 1 For a preliminary and longer version of this paper see Guillaumont (2000). See also Guillaumont (2001).


Over a period of 12 years Denhoff and Holden (1961) tested 8 drugs on pre-school children suffering from cerebral palsy for improvement in neuromuscular function including spasticity, behaviour, taste (acceptability) and toxicity. Objective tests were used for the first. The drugs examined were mephenesin (Myanesin, Tolserol), mephenesin with glycerol-alpha-ethyl-gamma-isopropyl ether (Lissephen), chlorpromazine, reserpine, zoxazolamine (Flexin), alpha-ethyl-beta-methylvaleramine (McN 181), carisoprodol (Soma), and emylcamate (Striatan). Beneficial results were seen in neuromotor function with both mephanesin and placebo. Placebo effects were greater than drug effects in neuromotor function and behaviour with Lissephen, but this drug was not tolerated in doses sufficient to reverse these effects. With chlorpromazine behaviour improved statistically, but the neuromotor effectiveness was secondary, occurring because the child was mentally relaxed and happy. Zoxazolamine gave improved behaviour, but the neuromotor effect was no better than that of the placebo. Reserpine was not tolerated, drowsiness taking place with a dose necessary to produce efficient performance. McN 181 was ineffective in doses tolerated and 6 cases were unchanged or worse as regards spasticity on soma. Striatan gave 6 of 14 improving in anxiety, but 10 of 18 did so with placebo and no statistical differences were found in anxiety score. The beneficial neuromotor effects of the drugs varied from 9 to 56 per cent. (mean 33.4) and of the placebos from 26 to 50 per cent. (mean 38.7). The authors point out that overall progress can be made when the child is mentally relaxed and happy, as when being treated with chlorpromazine.

The collected plant material was dried under shade, and the leaves of the plant were separated from the stem, and ground in a grinder. The powdered, dried leaves of plant (200 g) were extracted with methanol by cold maceration for 48 h with occasional shaking and filtered through Whatman filter paper ( No.1). The resulting filterate was concentrated to dryness and the yield was 5 % w/w.Male Wister rats weighing 250-450 g were used for the study. All rats were kept at room temperature in the animal house. The animal procedures were followed as per the internationally accepted ethical guidelines for the care of laboratory animals. Prior to the experiments, rats were fed with standard laboratory food for one week in order to adapt to the laboratory conditions. This study was approved by the Institutional Animal Ethical Committee of KMCH College of Pharmacy, Coimbatore, India.


A new technology in the field of bill handling has been investigated. Eleven methods of counting and separating cash in bulk from stacks are proposed. These are critiqued, and the design judged most promising is tested in prototype. That device utilizes a rubber contact wheel spun about two parallel axes to contact, buckle, count and lift bills. It descends into a stack as it cycles, forming a second stack (of counted notes) above itself. The prototype's performance is examined analytically to aid in optimization; the relationships predicted between parameters are found to be consistent with intuition. Also, pertinent forces are predicted within an order of magnitude. Furthermore, a software simulation of the prototype is provided, for use in investigating the effects of different device parameters. Final recommendations are then made, regarding the advancement of bill feeding technology. Thesis Supervisor: Harry West Title: Professor, Mechanical Engineering

The longitudinal and transverse impedance of many holes in a thick-wall liner have been calculated for hole dimensions that are small compared to the wavelength. These are shown to be small compared with the corresponding resistive wall impedances of the liner at the frequency of the lowest transverse coupled-bunch mode. Estimates are made of the effect of the propagation of TEM modes in the coaxial region between the liner and beam pipe, and these can be neglected for a sufficiently thick liner. Estimates are also made of the possible coherent effect of uniformly spaced holes


Background:  Complete traumatic amputation of upper limb in wrist area is relatively rare. During the past years thanks to advances in scientific and microscopic methods peripheral nerve surgery has increased the success rate of such surgeries. Case Presentation: An 18 year old man with his wrist has been cut for about 6 hours in an accident was referred to emergency Ward of Taleqani Hospital of Kermanshah. The patient suffered from complete cut of left wrist in car accident in 2008. The patient was really agitated and restless. His Blood pressure was 50/90 mm Hg and pulse rate was 120 per minute. Cut hand has been pressed and contaminated with soil and was wrapped in cloth and sent to the medical center. At first radius and ulnar bones were fixed by pin and articular capsule was sutured. In the second stage muscles were sutured. Arteries and veins in the third stage were anastomosed. Vessels were anastomosed end-to-end. Median, radial and ulnar nerves were restored by microscopic surgery after blood supply of hand has been flown. Finally, fasciotomy of organ was done to prevent compartment syndrome. Conclusion: Two years later it was realized that the patients' sense of touch, heat and pressure of hand was remarkably good in transplanted hand and the surgery was really successful.


Abstract— Photodynamic therapy (PDT) is a new modality for treatment of malignancy. In this paper, we reported the effect of UV activated dihematoporphyrin ether (DHE) on [3H] thymidine uptake and DNA synthesis in murine bladder tumor cells,MBT–2. Exponentially growing cells were pretreated with 0.05–5μg/ml of DHE for 30 min in complete darkness prior to irradiation with 0.15‐0.90 J/cm2 of UV light (265 nm). The rates of thymidine uptake and DNA synthesis were suppressed in a DHE concentration and photic energy dependent manner. Double reciprocal analysis on the kinetics of the thymidine uptake and DNA synthesis indicated that the inhibition was non‐competitive, i.e. decrease in both the apparent Km value and maximum velocity in DHE plus UV light treated cells. The activities of DNA polymerase a and (3 were determined by [*H] dATP incorporation into DNA of permeabilizedMBT–2 cells. DNA polymerase a activity was approximately 60% of the control after 0.45 J/cm2 of UV light exposure; a further inhibition of DNA polymerase a was observed when 0.5–5ng/W of DHE and UV photoradiation were combined. In contrast, a slight stimulation of DNA polymerase fJ was noted after a similar treatment. This study demonstrates that photodynamic therapy‐induced suppression of DNA synthesis inMBT–2 cells is a complex process involving in reduction of thymidine transport as well as the perturbation of the enzymes involved in DNA synthesis.


The steady functioning of the post-industrial type enterprise and its development as a complex dynamic system requires the use of decision-making processes of general or result indicators, an important place among which is data on intangible economic resources and their productive energy, expressed by indicators of the size and structure of intellectual capital. In the conditions of the post-industrial socio-economic environment, information and intellectual economic resources have a significant effect on the efficiency of the activity of both an individual economic entity and the national economy as a whole. One of the options for developing (improving) the intellectual capital accounting system is the accounting model - Accounting for the future (Accounting for the future‖ (AFTF)). This model is developed as a special tool for the formation of accounting financial reporting on the cost of an enterprise based on the use of technology budgeting capital of the enterprise. The Value Added Intellectual Impact Value (VAIC) model is a system of indicators to measure the value added generated by the enterprise's intellectual capital. The basis of the development of this model is the hypothesis that value added is the main indicator of the transformation of intangible assets into market assets of the enterprise. Existing standardization of accounting and reporting and standards for measuring intangible assets for financial reporting purposes do not provide a formalized value for a significant part of such objects. The lack of a valuation technique does not make it possible to uniquely identify the place of this type of economic resources in the accounting process, to formally represent them in the public reporting of the enterprise, first of all, to include them in the balance sheet for balancing the market and book value of the company. The use of intellectual capital by economic systems of any hierarchical level is a prerequisite for the implementation of the strategy of their innovation development, the formation of investment attractiveness and the provision of positions in the capital markets. The main complex criterion for assessing the modern economic entity is the value of equity, changes in its market value. Taking into account the fact that intellectual capital occupies a significant share in the total value of the equity capital of a post-industrial type enterprise, the development of a reliable methodology for its valuation and the principles of representation in capital and investment markets is an actual subject of modern economic science. The development of the underlying foundations for formalizing the indicators on the intellectual capital of an enterprise, obviously, should proceed from the principle that intellectual assets are intellectual capital that is fixed, stored, cataloged and accessible for familiarization.

In this paper, we introduce the plithogenic set (as generalization of crisp, fuzzy, intuitionistic fuzzy, and neutrosophic sets), which is a set whose elements are characterized by many attributes' values. An attribute value v has a corresponding (fuzzy, intuitionistic fuzzy, neutrosophic, or other types of sets) degree of appurtenance d(x,v) of the element x, to the set P, with respect to some given criteria. In order to obtain a better accuracy for the plithogenic aggregation operators in the plithogenic set, and for a more exact inclusion (partial order), a (fuzzy, intuitionistic fuzzy, or neutrosophic) contradiction (dissimilarity) degree is defined between each attribute value and the dominant (most important) attribute value. The plithogenic intersection and union are linear combinations of the fuzzy operators tnorm and tconorm, while the plithogenic complement, inclusion (inequality), equality are influenced by the attribute values contradiction (dissimilarity) degrees. This article offers some examples and applications of these new concepts in our everyday life.


—The importance of Customer Relationship Management (CRM) has never been higher. Thus, companies are forced to adopt new strategies to focus on customers, given the competitive climate in which they operate. Also, companies have been able to maintain customer data within large databases that contain all information related to customers, thanks to the tremendous technological development seen recently. Multilevel quantitative association mining is a significant field for achieving motivational associations between data components with multiple abstraction levels. This paper develops a methodology to support CRM to improve the relationship between retail companies and their customers in the retail sector to retain existing customers and attract more new customers, by applying data mining techniques using the genetic algorithm through which an integrated search is performed. The proposed model can be implemented because the proposed model does not need the minimum levels of support and trust required by the user, and it has been confirmed that the algorithm proposed in this research can powerfully create non-redundant fuzzy multi-level association rules, according to the results of these experiments.

There is a growing interest in the concept of emotional intelligence (El), as a result of a new Zeitgeist that embraces nontraditional views of intelligence, and a belief promulgated in the popular press that El holds the promise for solving many of society's most pressing problems. Two important bodies of writing on El, the work of Daniel Goleman and Peter Salovey & John Mayer, are discussed as illustrative of recent theorizing on El. The article discusses conceptual and measurement problems that presently challenge the usefulness of the El construct. It is suggested that El be tentatively viewed as a possible kind of intelligence, awaiting further theory development and validation.

Three typical cokes were used for experiments in order to clarify the relationship between coke properties and solution loss behavior and its influence on the post-reaction strength of coke. Isothermal reactions between coke and CO2 at 1050–1300 °C were stopped at a weight loss of 25%. The post-reaction strength of coke was tested by an I-Type tumbler. Coke chemical reactivity and pore structure were tested to analyze the coke properties. The results show that the reaction temperature caused the most serious degradation to three cokes that were different due to their different properties. If two kinds of coke have similar chemical reactivity, the one with the less developed pore structure has a lower temperature, causing the most serious degradation. If two kinds of coke have similar pore structure, the one with the higher chemical reactivity has a lower temperature, causing the most serious degradation. This knowledge contributes to a reference for evaluating the capability of coke strength for resisting solution loss.


With the continuous improvement of highway grade, slope protection is paid more and more attention to. Highway subgrade is wide, digging and filling are large. Especially in the mountainous areas, there have much high filling and excavation. If the slope reinforcement and protective measures are not effective, it is easy to result in all kinds of slope disease. Therefore, taking a mountain slope as an example, it discusses the engineering hydrogeological, then focus on the analysis of the application of comprehensive protection technology in treating high slope of this highway, which can provide reference for related engineering projects.


To achieve a goal of "no net loss" of wetland functions as well as acreage, it is important to know which functions wetlands in a specific region or watershed may individually provide, at what level. Although methods exist for assessing functions of Oregon wetlands (ORWAP; Adamus et al. 2009), site visits and hours of data collection are required to apply these to any wetland. Moreover, property access restrictions prohibit their use on many wetlands. Thus, when there is a comprehensive objective to assess all mapped wetlands in a region or watershed, time and manpower constraints require that spatial data be processed automatically using GIS, even though assessments of functions using such an approach have much lower levels of certainty.

The primary object of this project was to define criteria that would allow only the use of existing spatial databases (and only those with comprehensive coverage of the ecoregion) to identify the HGM class of mapped Willamette Ecoregion wetlands, and then apply those criteria automatically and systematically to every mapped wetland in the ecoregion, resulting in an HGM label for each mapped wetland. An ancillary goal was the creation of a database that describes over 200 attributes of each mapped wetland in the Willamette ecoregion, i.e., a regional wetland "profile."


Indonesia Port Corporation I (PT Pelabuhan Indonesia I (Persero)) or PT. Pelindo I is one of the Indonesian state-owned enterprises which manages port services in western Indonesia. Shipyard unit (Unit Galangan Kapal (UGK)) is a branch of PT. Pelindo I. At present, a problem arises if more than 2 ships are being repaired at once in the unit, UGK scheduling overlaps the repairing activities. In order to solve the problem, study of human factor is important. Human factor is the study of the limitations, capabilities, and human behavior, as well as its interaction with the product, environment, equipment and the establishment of tasks and activities. One part of the human factor is the human factor in system design. In order to improve the effectiveness of the system, the human factor must be involved in each phase of the design process in the system design. This includes a number of activities to obtain input specification work, therefore the working methods and the optimal amount of labor can be determined. Human factors engineering is the application of science that utilizes research on the human factor and use the basic knowledge to design, to repair and to install the system. This research method is causal, searching for the causes which led to delays in the completion of ship repairing. Through human factor engineering approach to the allocation of labor increased by 12.23 per cent of the actual conditions, so that the delay of ship repair were not found during normal conditions.


Antiferromagnetic (AFM) oscillators are of interest because of their potential to operate at THz frequencies, and thus to fill the ``terahertz gap''. Previous studies on AFM oscillators have focused on using the spin Hall effect to generate spin current, but other mechanisms exist. Here the authors investigate using spin current with an arbitrary polarization direction that is not simply due to the spin Hall effect. Their results will be useful for application of such oscillators, and more broadly for understanding AFM spin dynamics.


FROM STUDIES which have been made on certain fungi belonging to the genus Glomerella, the evidence supports the conclusion that there is a close association between two distinct strains or strain types which have been designated as plus and minus. The plus strain is the one ordinarily picked up and cultured. When ascospores are isolated from this strain, cultures of both the plus and minus strains are readily obtained. It is also known that when the plus and minus strains are grown in the same plate, a ridge of perithecia forms very rapidly on the line wlhere they come together. The perithecia develop more rapidly in this ridge than they do in the small glomerate masses which are produced by a plus culture growing by itself. When the ascospores from a ridge are cultured, it has been found that ordinarily the asci contain either four plus and four minus spores or else eight minus spores. As the same segregation occurs in the plus strain alone, it has not been possible to prove definitely that the ridge of perithecia on the line of contact follows a fertilization between the two strains as was suggested in an early paper (Edgerton, 1914), or is merely due to some stimulus. The object of this paper is to present evidence to show that a fertilization does take place between the plus and minus strains. A culture of the plus type from Ipomoea has provided the way for obtaining such evidence. As reported in a previous paper (Lucas, Chilton, and Edgerton, 1944), from this culture and its plus and minus progeny several variants were obtained which were definitely distinct from the plus and minus strains usually isolated from ascospores. Certain of these when grown in plates with other strains produced perithecial ridges on lines of contact. From these ridges it was again possible to isolate ascospores and identify the cultures developing from them. Among the variants obtained from the Ipomoea culture were two strains which were of great aid in the present investigations. These were a strain definitely of the plus type but differing in certain respects from the original better-known one and a culture of the minus type distinct from the original. These two variants and the common plus and minus strains have been grown in plates in all possible combinations. The term type is introduced in this paper in order to group strains which differ in some respects but in general are similar. There are strains of the plus type which are unlike in certain characteristics, and similarly there are different strains of the minus type. For the present no other types are being considered. DESCRIPTIONS OF CULTURES USED.-Cultures of the ordinary plus and minus strains and of the two


Using structural analysis methods,the hydration process of cementitious materials and the effect mechanism of the polymerization degree of [Si(Al)O4] on the solidification of Na+ during hydration process were studied.The results indicate that the [Si(Al)O4] polymerization degree in raw materials had a remarkable influence on the solidification of Na+.When Si existed in the form of SiQ0 and SiQ1,it depolymerized in the early stage of hydration process,and then reacted with Ca2+ in the solution to form high Ca/Si C-S-H gel.When Si existed in the form of SiQ2 and SiQ3,it was depolymerized mainly in the late stage of hydration process,then Al readily entered the [Si(Al)O4] tetrahedral sites and made the hydration into low Ca/Si(Na,Al)-C-S-H gel,which was more useful for the solidification of Na+.When Si existed in the form of SiQ4,it was not useful for the solidification of Na+.


Abstract This paper reports fossil plants of Archaeamphora longicervia gen. et sp. nov. Li from the Early Cretaceous Yixian Formation, northeastern China. The plants are herbaceous and similar to modern sarraceniaceans in having spirally arranged developed/underdeveloped pitchers and phyllodia-like leaves that have parallel major veins and reticulate meshes, distinctive honey-spoon-like structures and porous glands. The intimately associated seeds are reticulate-tuberculate and winged, resembling sarraceniacean seeds. The unique pitcher and characteristic seed suggest a relationship to Sarraceniaceae. The relationship to Angiosperms is also supported with fossil molecule oleanane found from Archaeamphora, using GC-MS. Archaeamphora demonstrates the earliest carnivorous plant and the only fossil record of pitcher plants. Also, as the third genus of the oldest Angiosperms, the existence of such a derived taxon suggests that flowering plants should have originated much earlier.

This paper represents the method to manipulate the objects with the upper body of a humanoid robot by capturing human motions in real-time. To control the upper body of a humanoid robot and make it behave as a human does, we define several virtual spring-damper elements between the humanoid robot and the human. The resultant motions given by the virtual forces of the elements lead the humanoid robot to move as the human acts. We employ the forward dynamics formulation to represent the dynamics model of humanoid upper body as an articulated body system with those virtual spring-damper elements for obtaining the resultant motions. Due to considering the whole dynamics of upper body, it is easy to resolve the ill-posedness or singularity of inverse kinematics problem and to involve external forces. The present method may be of use in teaching a humanoid robot working skills or detailed motions of a human. For validating the proposed method, we transited human motions to a humanoid robot using a motion capture system and controlled the robot to grasp an object passed by a person simultaneously.

Objective:To investigate the effect of Canstatin mediated by Lentivirus(pGC-FU-Canstatin)on the proliferation and apoptosis of vascular endothelial cells in vitro.Methods:Canstatin gene was amplified from plasmid pSPORT1-Sfi by PCR.The plasmid of pGC-FU and PCR products of Canstatin gene were double-digested by with restrictive endonucleases Age I and EcoR I to generate the lentiviral expression vector pGC-FU-Canstatin by gene recombination technique.The corrected Canstatin was confirmed by endoenzym digestion,sequencing.Recombinant lentiviruses were produced by 293T cells following the co-transfection of pGC-FU-Canstatin,with the packaging plasmids pHelper 1.0 and pHelper 2.0.The viral titer was detected by Western-blotting.The resulting combinant lentiviruses which carrying Canstatin were then used to transfect huaman umbilical vein endothelial cells.Canstatin protein expression in huaman umbilical vein endothelial cells was dectected by Western blotting analysis.The effects of Canstatin gene on the proliferation of ECV304 cells were measured by MTT assay.Morphological change of apoptosis of ECV304 cells was determined by TUNEL staining,and by FCM with AnnexinV/P1 costaining.Results:In the cellular proliferarion assay in vitro,the number of ECV304 cells in GC-FU-Canstatin group was much smaller than that in GC-FU group and PBS group(P0.01).After 72h of treatment with GC-FU-Canstatin,the ECV304 cells had characteristics of apoptosis revealed by TUNEL staining.The apoptosis rate in GC-FU-Canstatin group(21.63±1.32)% was much higher than that in GC-FU group(2.66±0.69)% and PBS group(2.87±0.76)%(P0.01).Conclusion:The Canstatin gene mediated by lentivirus has an inhibitory effect on the proliferation of human umbilical vein endothelium cells ECV304 in vitro,and could induce the apoptosis of human umbilical vein endothelium cells in vitro.


— In recent years, many techniques have been proposed so as to enable resource-constrained devices to consume or deliver live multimedia streams. The majority of the existing techniques use distributed multimedia services and powerful servers to handle streams on behalf of clients. This is due to the fact that, multimedia streaming, when smartphones act as both clients and servers, can generate many challenges due to the heterogeneity of the multimedia streaming protocols, the media formats and codecs supported by today's smartphones. In addition, multimedia processing is resource consuming and, in many cases, unsuitable for a plethora of resource-constrained devices. To overcome these challenges, we present MobiStream a device-to-device multimedia streaming system for resource-constrained devices that achieves efficient handling of live multimedia streams. The design of MobiStream architecture provides solutions to several issues including resource constraints, streaming among heterogeneous operating systems and platforms, generation, synchronization and presentation of multimedia streams. We have developed the MobiStream prototype system on Java 2 SE and Android platforms; this paper presents the implementation details and the experimental evaluation of our system.


The existence of harmonics is one of the significant means of deteriorating the quality of an electric power supply. In order to fully understand the problems caused by harmonics, sources of electric power harmonics needs to be identified and this normally requires power quality monitoring and analysis. However, monitoring usually generates vast amount of data which makes manual inspection of the disturbance waveforms a tedious and time-consuming task. Therefore, it is desirable that the data collection process is automated such that monitoring equipment not only captures harmonic waveforms but also performs the task of recognizing the various types of nonlinear loads present in a system. With such an automated system, faster and more efficient analysis of the databases can be achieved. The issue of automatic analysis of various power quality disturbances has been addressed in the form of the development of expert systems for power quality event identification or the classification of disturbances such as transients and voltage sags (Kazibwel and Sendaula 1992). The expert system for analyzing power system harmonics focuses on symptoms associated with harmonics related problems and providing possible solutions (Schlabbach 1994, Shipp et al 1995).


A simple and precise RP-HPLC method was developed and validated for the determination of ambrisentan in pharmaceutical dosage forms. Chromatography was carried out on Phenomenex C18 (150 x 4.6mm, 5μm) column using a mobile phase of 10mM ammonium acetate: acetonitrile (65:35% V/V) at a flow rate of 1.0mL/min. The analyte was monitored using UV detector at 262 nm. The retention time was found to be 2.696 minutes. The proposed method was found to be linear in the concentration range of 10-50 μg/mL with a correlation coefficient of 0.999. The mean recoveries obtained for ambrisentan were in the range of 99.24 -99.66%. The developed method has been statistically validated according to ICH guidelines and found to be simple, precise and accurate with the prescribed values. Thus the proposed method was compatible to LC-MS and successfully applied for the estimation of Ambrisentan in routine quality control analysis in bulk and its formulations.
