COMMUNICATIONS OF THE ACM September 2000/Vol. 43, No. 9 91 P resentations are an ubiquitous feature of organizational life. They are a key method for achieving a clear understanding of complex ideas among large groups of people. However, there is often little time for genuine interaction among presenters and their audiences. Imagine a presentation where the entire audience jumped into a lively debate as soon as the presentation began. Imagine the presenter continued unconcerned, that everybody heard the presentation without losing the thread of the discussion in the audience. Imagine the participants could report the discussions months later with complete accuracy. With standard methods this would be impossible, yet with Group Support Systems (GSS) this scenario can be realized fairly easily. A GSS is a suite of software tools for focusing and structuring group deliberation, while reducing the cognitive costs of communication and information access among teams making a joint cognitive effort toward a goal [3]. GSS participants simultaneously type their contributions into a network of computers. The software immediately makes all contributions available to the other participants. If the team feels it appropriate, the GSS allows for anonymous input. A GSS may have tools for collaborative idea generation and organization, electronic polling, simultaneous document authoring, and multicriteria decision-making, among others. Each tool creates a different kind of group dynamic. One may encourage participants to diverge from customary thought patterns, while another may cause them to converge quickly on key issues. One may encourage them to contribute in great depth and detail, while another may move them to a broader, big-picture view. Here, we rethink the traditional presentation-and-discussion structure, exploring means that may enhance its value for both audiences and presenters. Supercharging the audience through simultaneous discussions during presentations. ■ Robert M. Davison and Robert O. Briggs


Abstract In this study, an equivalent multi-body dynamics model of a rotary compressor for a household air-conditioner is established to predict its vibration responses when eccentric masses on the crankshaft, cyclic gas loads, torque ripple of the motor, connections with rubber washers, and the intake tube and exhaust tube are considered. Practical experiments for measuring the vibration acceleration of the compressor are conducted to validate the reliability and equivalence of the established model. The design of experiments method is employed to determine the optimal counterweights. This study determines the gas loads required to be considered in the counterweight design to attenuate the compressor vibration effectively. In addition, an optimal assembly angle for two counterweights is attained to reduce the compressor vibration.

The aim of this study is to show student perception of the value of library reference and consultation work in the building of information literacy skills. Using student answers to questions about library research help received in a required first year course, the authors analyzed motivations for use of librarian aid, and the types of assistance sought and that ideally could have been utilized. The authors found students primarily received librarian help with locating books, and that students often believed they would have benefited from more in-depth assistance but did not ask for it.


Peripheral authentication is an important aspect in the vehicle networks to provide services to only authenticated peripherals and a security to internal vehicle modules such as anti-lock braking system, power-train control module, engine control unit, transmission control unit, and tire pressure monitoring. In this paper a three-way handshake scheme is proposed for a vehicle to a keyfob authentication. A keyfob is a key with a secure hardware that communicates and authenticates the vehicle over the wireless channel. Conventionally, a vehicle to keyfob authentication is realized through a challenge-response verification protocol. An authentic coupling between the vehicle identity and the keyfob avoids any illegal access to the vehicle. However, these authentication messages can be relayed by an active adversary, thereby, can amplify the actual distance between an authentic vehicle and a keyfob. Eventually, an adversary can possibly gain access to the vehicle by relaying wireless signals and without any effort to generate or decode the secret credentials. Hence, the vehicle to keyfob authentication scheme must contain an additional attribute verification such as physical movement of a keyfob holder.
Our solution is a two-party and three-way handshake scheme with proactive and reactive commitment verification. The proposed solution also uses a time interval verification such that both vehicle and keyfob would yield a similar locomotion pattern of a dynamic keyfob within a similar observational time interval. Hence, the solution is different from the distance bounding protocols that require multiple iterations for the round-trip delay measurement. The proposed scheme is shown to be adaptable with the existing commitment scheme such as Schnorr identification scheme and Pedersen commitment scheme.


During steel pipe fabrication, hot rolled coil steel will undergo coiling and uncoiling process, where the steel plate is bent repeatedly. When cyclic loading is imposed on steel, tensile and compressive stress will occur in it resulting in softening caused by Bauschinger effect. This research is focused on Bauschinger effect and cyclic loading during coiling and uncoiling process on API 5L B and API 5L X56 steel. Both types of steel were given repeated bend loading with variation in loading cycle and the curvature radius. The steel's response was then observed by using tensile testing, microhardness testing, and microstructure observation. A decrease in yield strength is observed during lower cycles and on smaller radii. After higher loading cycle, the yield strength of the steel was increased. Microhardness testing also reported similar results on the subsurface part of the steel where loading is at its highest.

Abstract:With the emergence of a global concept of childhood based on the 1989 United Nations Convention on the Rights of the Child there has been a growing interest in increasing children's participation in society. This paper explores the legal, political, institutional, and cultural context for child participation in Bangladesh where marginalized children, such as child domestic workers, are still largely left out of the participation process. Opportunities are very limited for child domestic workers to make their own decisions regarding matters such as choosing employers, working hours, schooling, marriage, and how to spend their own salaries. Factors that limit their participation include cultural attitudes, workloads, and lack of suitable educational programs. Increasing the participation of child domestic workers in society, and helping them to find their own agency in matters affecting their lives will require a comprehensive effort to be made in many sectors and on many scales.


The specialized computer programs used in the collection, organization, analysis, interpretation and presentation of the data are known as statistical software. Descriptive statistics and inferential statistics are two main statistical methodologies in some of the software used in data analysis. Descriptive statistics summarizes data in a sample using indices such as mean or standard deviation. Inferential statistics draws conclusions that are subject to random variables such as observational errors and sampling variation. In this study, statistical software used in data analysis is examined under two main headings as open source (free) and licensed (paid). For this purpose, 5 most commonly used software were selected from each groups. Statistical analyzes and analysis outputs of this selected software have been examined comparatively. As a result of this study, the features of licensed and unlicensed programs are presented to the researchers in a comparative way.


Objective To determine if the erythrocyte membrane Ca~(2+).Mg~(2+)-ATPase activity can be an index which response the function of thyroid hormone in the cellular level,the enzyme activity were measured in patients with hypothyroidism and re-examined in euthyroid state after 3 months L-T_4 replacement.Methods The erythrocyte membrane was prepared by hypotonic-lyses and different centrifugation under 4℃.The enzyme activity was expressed by the amount of released phosphorus(Pi)from ATP under the catalyzed of membrane solution.The released Pi with calcium was act as Total-ATPsae and the Pi without calcium is act as Mg~(2+)-ATPase,the Ca~(2+).Mg~(2+)-ATPase was obtained by the difference of the two.Results The activity was significantly decreased in the hypothyroidism and returned to normal after euthyroid was achieved by 3 months of Ca~(2+).Mg~(2+)_4 replacement treatment.Conclusion This study provides clinical confirmation of suggesting that the set-point of Ca~(2+).Mg~(2+)-ATPase activity is,in part,a function of endogenous thyroid hormone levels.This enzyme may be an index which response the function of thyroid hormone in the cell level and may be helpful for the diagnosis of thyroid disease.


We analyzed nietzsches conception of the death of god. The atheist "of rigour" (valadier) detected in this phenomenon different nihilisms (reactive, negative, passive, active). The "logic of death" gave us the possibility of thinking the "death of man", discovered by the structuralism of foucault. Then the same logic brought us to the threat of the "death of the world", world already dead as a creation et near to agony as a world seen as an object. The conclusion of the work is founded on nietzsches anti-nihilism and on a philosophy of life, which is seen as an essentially "sacred" phenomenon.


Usually Tian Han was ranked to romatism.but he showed a special interesting in New-Romantism in his early time.Because new-romantism and romantism are same in which they all emphasize particularly on subjective, the New-Romantism is the pronoun of modernism in 20s. They are unlike in fact. The contradiction of spirit and flesh, the symbolic method and the relative attitude in Tian Han' s drama represent a strong modernistic trend.


To enhance the control accuracy of the variable rate fertilization control system and to solve the problems of long delay time and high overshoot of the variable rate fertilization general PID controller, a variable rate fertilization control system was designed based on improved PID. The structure of a designed variable rate fertilizer applicator was introduced. The fertilizer apparatus and the stepping motor mathematical model were built. An anti integration saturation method was adopted to improve the integral of the general PID controller. An incomplete derivation method was adopted to improve the differential of the general PID controller. The improved PID controller mathematical model and its control block map were built. Finally, the simulation experiment of the step motor rev control were made, which included 80r/min and 120r/min speed tracking contrast experiments. From the simulation experiment result it could be seen that the improved PID controller was better than the general PID controller in terms of decreasing overshoot and shorten delay time.


Introduction Adolescents with attention deficit hyperactivity disorder face neurocognitive impairments that impede their occupational functioning. The Cognitive-Functional model is a metacognitive occupational therapy intervention for individuals with attention deficit hyperactivity disorder that harnesses self-awareness and strategy behavior to support participation in an individualized occupational context. This study explored preliminary feasibility and efficacy of the Cognitive Functional model adapted for adolescents with attention deficit hyperactivity disorder, the Teen Cognitive-Functional intervention. Method A mixed method feasibility study including 22 adolescents with attention deficit hyperactivity disorder and their parents was conducted. Pre–post assessments included: occupational performance (Canadian Occupational Performance Measure); executive functioning (Behavior Rating Inventory of Executive Function); self-awareness and strategy behavior (Self-Regulation Skills Interview). Results Modest attrition and high satisfaction from Teen Cognitive-Functional intervention were found. Significant improvements were reported in adolescents' occupational performance, executive functioning and strategy behavior. No significant gains were found in adolescents' self-awareness. Adolescents' strategy behavior was correlated with parent-rated occupational performance. Qualitative analysis of the strategies reported by the adolescents after intervention revealed three categories: "self-determined choices"; "plan and organize" and "adaptations." Conclusion This study provides initial support for feasibility of the Teen Cognitive-Functional intervention and its potential efficacy in promoting occupational performance, executive functioning and strategy behavior. Controlled studies are needed to further validate these findings.


The form factors of the $K^+ \to \gamma$ transition are studied in the light-front quark model and chiral perturbation theory of $O(p^6)$. The decay spectrum of $K^+ \to e^+ \nu_{e}\gamma$, dominated by the structure dependent contribution, is illustrated in both models.


In this contribution we focus on thermally induced absorptive optical nonlinearities in II-VI semiconductors. We demonstrate an optical oscillator by introducing the sample into a hybrid ring resonator with long round trip time. In the case of only marginally bistable input-output characteristics (realized with a CdS single crystal) we get the following dynamical behavior: For high input intensities the oscillation period is a multiple of the delay time. When decreasing the input intensity relaxation oscillations that stabilize the system and prevent it from a transition to deterministic chaos become important. Additionally we investigate the spatiotemporal dynamics of the system if a large diameter holding beam is switched by a small and short light pulse. Here we find switching waves and metastable temperature profiles.


This paper reports an experimental study carried out to investigate the influence of synergic effects of metakaolin (MK) and Class C fly ash (FA) and ground granulated blast-furnace slag (GGBFS) with different percent , on the mechanical and physical properties of the ternary blended such as setting times, strength, water absorption and porosity percent. The efficiency for immobilization cesium (Cs-137) was evaluated by the leaching test ANSI/ANS 16.1-2003. The results indicated that fly ash and ground granulated blast-furnace slag replacement generally increased cement setting time, while effect of metakaolin replacement decreased cement setting time. The results showed that the metakaolin, fly ash and ground granulated blast-furnace slag provides a positive effect on mechanical and physical properties depending on amount of replacement. Besides, the sample incorporating the ternary blend of cement with 10% metakaolin, 25% fly ash and 35 % and ground granulated blast-furnace slag (CFGM2) , showed higher compressive strength and decreasing of the leachability of cesium (Cs-137) than that of the normal cement or cement mixed with metakaolin or fly ash or ground granulated blast-furnace slag respectively. This blend proved to be the optimum combination for achieving maximum synergic effect.


The multi-copters are one of the important aircrafts in the world because they are used in both military and civil application. The problem of these aircrafts is the low efficiency of its propellers. That's why, it is necessary to study the aerodynamic structure around every rotor. In this paper, a computer simulation has been done to study the aerodynamic structure around a NACA 6409 airfoil rotor. The numerical model is based on the resolution of the Navier-Stockes equations with a standard k-e model. Then, the finite volume discretization of these equations leads to solve it. The local characteristics of the aerodynamic structure are extracted using the software Solidworks Flow Simulation and the validation is done with comparison with anterior result of Alexandrov (2013).


Currently, one out of five adults in the United States has a disability. As the population ages, the number of adults with disabilities will swell. As critical government services move online, the need for accessibility grows. However, poor accessibility and usability in authentication methods can form a barrier to the use of important websites, such as tax and benefit services. Given current commercial trends, biometric authentication methods will be used more widely to ensure secure access to such services. There is currently a dearth of research into both accessibility and usability of authentication modalities, including biometric methods. Thus, we investigated the usability of biometric authentication schemes for users with and without disabilities (vision or hearing). We comparatively evaluated three biometric authentication schemes (fingerprint, eye, and palm recognition) and one non-biometric authentication scheme (PIN) on effectiveness, efficiency, and perceived usability. Traditional and biometric schemes showed some usability differences. Biometric schemes' usability often differed based on whether the interaction required dynamic device positioning (placing and holding the device in relation to specific points on the user's frame). Biometrics that required dynamic device positioning (ex. palm) had lower usability for participants with limited or no vision. We therefore put forth dynamic device positioning as a new consideration for usability evaluations of biometrics.


Summary: This study evaluates the leaf anatomy pattern of Gaillardia cabrerae Covas, an exclusive endemic camephyte from the Lihue Calel National Park, province of La Pampa, Argentina. Leaf cross sections and peelings of plants growing in two different populations were used to determine the basic leaf anatomy patterns and to estimate the influence of growth conditions in the two microhabitats. The analysis showed differences in epidermal cells area, stomata density and main diameter, lacunar parenchyma cells and central vascular bundle diameter and palisade parenchyma cells dimensions. These aspects might be reflecting environmental conditions of the populations, especially sun exposure and soil moisture. The results provide information on the relationship of the species to its environment, which could be used in the establishment of conservation policies.


The survival of adults and immatures, and reproduction at rates of 150, 300 and 900 ppm a.i. of azinphosmethyl were compared among four types of Amblyseius finlandicus females and their offspring; a laboratory-selected colony (SEL16) resistant to azinphosmethyl, an unselected base colony (Tuorla), reciprocal F1 females from crosses between SEL16 and a very susceptible colony (Hiekkaharju). The SEL16 and reciprocal F1 females had a higher survivorship than the unselected Tuorla base colony after 2 and 4 days on leaves treated with the three concentrations of insecticide. Azinphosmethyl decreased oviposition by the surviving females of all types, but the decrease was smaller in the SEL16 strain than in the base colony. The survivorship of immatures of SEL16 on fresh azinphosmethyl residues after 6 days was low at all three concentrations, but no survivors were found in the base colony at any of the concentrations. Females deposited significantly more eggs on the untreated areas of the leaves. The importance...

In this deliverable, smart antenna based interference mitigation methods for WINNER are presented. These methods include beamforming techniques, transmit diversity techniques, and receive diversity and spatial interference suppression techniques. The methods are investigated in terms of what requirements they put on the system, and the performance they can achieve are assessed by means of computer simulations. Based on that, recommendations for interference mitigation are given. Executive summary The WINNER radio interface is designed to provide users with high quality of service wireless access. It should further be configurable to a wide range of scenarios, be spectrally efficient and allow for a cost-efficient deployment. One possible means to improve the spectrum efficiency and limit the deployment cost is to create a radio interface that is inherently robust to interference. With a high tolerable interference level the load in the radio network may be increased without degrading the user's quality of service. That is, more users may be served in the same spectrum. In general, radio communication links may experience several kinds of interference like inter-symbol interference (ISI), multiple access interference (MAI) and interference from external sources. ISI may be caused by a time dispersive radio channel while MAI appears when the limited set of radio resources is re-used throughout the system. In order to reach high spectrum efficiency, it is important that the radio interface in particular can handle MAI. The MAI can originate either from the own cell, so called intra-cell interference, or from other cells, so called inter-cell interference. Since the multiple access schemes in WINNER are designed to be orthogonal within a cell, there will be no, or very little, intra-cell interference. In other words, the MAI in a WINNER network mainly comprises inter-cell interference. There are different methods available to mitigate inter-cell interference. Interference averaging techniques aim at average the interference over all users, thereby reducing the interference experienced by some users. Interference avoidance techniques on the other hand, aim at explicitly coordinate and avoid interference, e.g. by setting restrictions on how the radio resources are used. However, in this deliverable it has been investigated how smart antennas can be used to mitigate inter-cell interference. The starting point for the work was the WINNER multiple antenna concept, and it was first investigated how it can be utilised for interference mitigation. The identified methods can be divided in three categories: beamforming techniques, transmit diversity techniques, and receive diversity …


The first micromachined bimorph organic ciliary array with on-chip CMOS circuitry is presented. This device is composed of an 8/spl times/8 array of cells each having four orthogonally oriented actuators in on overall die-size of 9.4 mm/spl times/9.4 mm. The polyimide based actuators were fabricated directly above the selection and drive circuitry. Selection and activation of actuators in this array shows that integration was successful. The integration of CMOS electronics and MEMS micromechanisms allows the implementation of new task-level micromanipulation strategies. New low-level control algorithms (actuator gaits) were also demonstrated. The array was programmed to perform several kinds of manipulation tasks, including linear translation, diagonal motion, as well as vector field operations such as squeeze field and radial field orienting and centering. Preliminary experiments were also performed using thin silicon dice of about 3 mm/spl times/3 mm/spl times/0.5 mm size as the object being moved.

Objective: Previous epidemiological studies have inconsistently linked various occupations and industries to pancreatic cancer risk. Methods: We analyzed data from a population-based case–control study conducted in Iowa involving 376 histologically confirmed incident pancreatic cancer cases and 2434 control subjects. Results: A significantly increased risk was observed among men who worked in the following industries: chemical and allied products, transportation, and elementary and secondary schools. Increased risks also were observed in men who were employed as truck drivers; railroad brake, signal, and switch operators; purchasing agents and buyers; teachers; insurance agents; and retail supervisors. Among women, a significantly increased risk of pancreatic cancer was found for employment in furniture and home furnishing stores, and a borderline significantly increased risk among textile sewing machine operators and tenders. Conclusions: Working in several occupations and industries was associated with an increased risk of pancreatic cancer in this study, and these associations warrant further investigation.


In the paper, a leg sole mechanism suitable for multi legged wall climbing robot is proposed. Using this kind of leg mechanism, the robot not only can climb from ground to wall easily, but has the possibility of adapting to such non plane surfaces as spherical or cylindrical ones. The leg sole mechanism is one based on a plane pantograph attached with two sets of four bar linkages in order for the robot to control the attitude of the sole. The paper gives discussion of mechanical configuration,drive/transmission schemes and structure of the leg sole mechanism.


Abstract Acrylonitrile butadiene styrene+20 wt-% polycarbonate (PC)/27 wt-% aluminium flake metallised plastics were immersed in aqueous H2SO4 for chemical roughening. The adhesive strengths of the metallised plastics that were roughened at various corrosion temperatures (30–90°C) for various times (10–30 min) with styrene–ethylene–butene–styrene at various melting temperatures (180–220°C) were investigated. Experimental results indicate that the aluminium flakes reduce the activation energy of the metallised plastics in aqueous H2SO4 at 30–70°C. The roughness and the weight rate of the roughened metallised plastics increase with corrosion temperature and time. Corrosion at 70°C for 10 min yields the largest effective adhesive area and adhesive strength. The adhesive strength increases with the melting temperature of styrene–ethylene–butene–styrene.


Directional-coupler (DC)-based switching systems can switch signals at the rate of several terabits per second. Such switches can also transmit signals with multiple wavelengths simultaneously. Despite these advantages, DCs suffer from an intrinsic crosstalk problem that must be overcome in building a robust switching system. In this paper, the principles of constructing strictly nonblocking DC-based photonic switching systems under various crosstalk constraints are explored. We demonstrate how crosstalk adds a new dimension to the theory of switching systems. We find the sufficient nonblocking condition for photonic networks under crosstalk constraints and demonstrate that some well-known nonblocking networks can tolerate a stricter crosstalk constraint while retaining their hardware complexity. The theory developed in the paper can guide us in making the design tradeoff between the level of crosstalk and the amount of hardware.


Bronchogenic cysts develop most commonly in the mediastinum posterior to the carina. Retroperitoneal bronchogenic cysts are rare developmental anomalies arising from the accessory lung buds of the foregut. We report a retroperitoneal bronchogenic cyst that was managed with retroperitoneoscopic surgery. CASE REPORT A 41-year-old woman presented with left flank pain 1 year in duration. Abdominal computerized tomography and ultrasonography demonstrated a 5.5 5.2 9.2 cm. cystic mass in the left suprarenal region (fig. 1, A). Magnetic resonance imaging (MRI) showed a well circumscribed retroperitoneal mass with high signal intensity on T1 and T2-weighted images (fig. 1, B and C). The cyst was believed to be proteinaceous. Abdominal aortography and renal angiography did not reveal any vascularity in the suspected area. Based on preoperative evaluation, retroperitoneal bronchogenic cyst, teratoma, neurogenic tumor and adrenal cyst were considered possible diagnoses. The patient underwent retroperitoneoscopy with 4 trocars inserted into the retroperitoneal space. Surgical exploration demonstrated no direct connection with the gastrointestinal tract, but the tumor was adherent to the adjacent tissue and was resected en bloc with difficulty. Histopathological examination showed that the cyst was lined with tall columnar epithelium without atypia, and the cyst wall contained thin smooth muscle bundles, seromucous glands and mature hyaline cartilage (fig. 2). Final diagnosis was bronchogenic cyst. Postoperative course was uneventful, and the patient required no analgesics. She was discharged home on postoperative day 7. DISCUSSION


The article deals with the policy of "fraternal protection" of indigenous people and the intrusion of land into their awnings, articulated with the colonization project implemented by the republican government in the north of Rio Grande do Sul, via the Land and Colonization Directorate. It initially analyzes the policy of fraternal protection of indigenous people, and then the delimitation of the space of indigenous awnings and the release of public land for colonization, as well as the unfolding of this policy in the daily activities of the Land and Colonization Commission. We conclude that the policy of "fraternal protection" of the positivist government, in particular of its most humanist wing, was confronted with unscrupulous public officials, who did not know the reality of the indigenous people and striked actions that produced conflicts within the public sphere in charge of the colonization processes and with the indigenous people. We also conclude that there were multiple interests around the land, a fact that resulted in the indigenous villages.
Keywords: Rio Grande do Sul. Indigenous awnings. Fraternal protection.


Microhabitat relationships between four sympatric small mammal species (Peromyscus leucopus, Ochrotomys nuttalli, Blarina brevicauda, and Tamias striatus) were examined to determine if their discriminant analysis of small mammal habitat represented a unique habitat utilization pattern for a specific small mammal community. The authors concluded that habitat is only one of many dimensions to be considered when studying the interactions of sympatric species. Reproductive strategy, activity patterns, and other factors make up the n-dimensional hyperspace of an animal's niche. Thus differences in habitat usage alone cannot be used to determine niche overlap and competition between species. (JMT)


After introducing a two-dimensional (2-D) model for the class of quarter-plane-causal, recursive and separable in denominator (CRSD) filters, a technique for approximating a given 2-D filter by a CRSD one is presented which also yields a model reduction procedure. Both the stability and minimality properties of the approximate model are explored. An example is also given to illustrate the proposed technique.


In the field the civil engineering, the durability of the concrete assemblies using adhesives is widely conditioned by the properties of the interface between the resin and the mineral support (concrete). In this context we were interested, at first, in the molecular interactions in the interface between an epoxy resin and cement paste by a several technical approach based on the spectroscopy XPS and IR, the DSC, and inverse gas chromatography (IGC). Besides, the study by " small area XPS " of the interphase of cement paste / adhesive revealed, on a sample in conditions Real, the structural modification of the lines Ca2p, N1s and Cl s, what lets think that this zone is the seat of chemical reactions facilitating the adhesion substrate-resin. Seen the complex structure of cement pastes, we were secondly interested in the interactions between the mains hydrated products of cements (model compounds) and the epoxy resin. Finally, we strengthened the epoxy resin by exfoliated nanocomposites MMT/PGMA (where PGMA is the poly(methacrylate of glycidyl)) obtained by ATRP. These nanocomposites were characterized by various methods to know XRD, XPS, TGA, FTIR. We then characterized the viscoelastic properties of the ternary mixtures MMT/PGMA/epoxy resin.


SUMMARY Following both a low and high plane of winter feeding two groups of 18 bullocks each were stocked at 2·5 (low), 4·3 (medium) and 6·2 (high) bullocks per hectare. The Hereford × Shorthorn bullocks averaging 350 kg live weight were rotationally grazed on ten plots, seven of which contained a H.I. white clover mixture and the remaining three contained permanent pasture. Pasture digestibility and intake were determined for 16 weekly periods between early April and late September. In vitro digestibility was determined on samples obtained by means of two rumen-fistulated bullocks. A gelatin capsule containing 10 g of chromic oxide was administered daily to each bullock to estimate faecal output. Digestibility, faecal output and intake were expressed on both a dry and organic-matter basis. Increasing the stocking rate resulted in a corresponding decrease in organic matter (OM) percentage of the faeces but the magnitude of the differences varied throughout the growing season. The average decline (all 16 periods) was linear, the OM percentage of faeces being 80·9, 76·8 and 72·6 for low, medium and high stocking rates, respectively. Faecal ash content of rectal samples and those taken from the pasture differed significantly only in a few instances, indicating that pasture faecal contamination may not be serious if careful sampling is practised. Higher ash intakes at high stocking intensities are reflected in herbage intake errors when results are expressed as dry matter instead of organic matter.


Noise is always inevitably appeared in images, which directly affects the performance of machine vision applications. Currently, the commonly used denoising methods can be divided into three strategies: the filtering-based, model-based, and deep learning-based methods. However, they are always difficult to get the considerable accuracy and efficiency simultaneously. In this study, a novel denoising method based on autocorrelation function is investigated, which improve the image quality by utilizing the independence of useful periodic information and noise. Simulations and experiments compared with the current denoising methods confirm that the investigated method has a good comprehensive effect on noise reduction and efficiency improvement.


High energy nuclear physics experiments started about a decade ago with the aim of studying quark gluon plasmas (QGP) in the laboratory. Statistical QCD predicts that in nuclear collisions at ultra-relativistic energies the quarks and gluons in hadrons will be momentarily deconfined into a phase of matter containing free quarks and gluons in the form of a plasma. This quark gluon plasma is also thought to have existed in the very early history of the evolution of the Universe, some 10 microseconds after the Big Bang when the extremely hot blob of energy started to cool and be converted into matter. Thus the study of ultra-relativistic nuclear collisions is important from the point of view of nuclear and high energy physics, astrophysics and cosmology. In these studies new detectors are required.


A weak nonlinear method of dominant balance is used to describe the fluid dynamics in a bilayer system in the vicinity of phase-change instability. The calculations are performed for a case where gravity and Marangoni effects are ignored. They give us an estimate of the enhancement of heat transfer and, equally importantly, lend credence to physical arguments on the effect of vapor dynamics on the instability.

Background: Acetaminophen (PCT) is known for its pro-oxidant properties, which neutralized by the presence of internal antioxidants such as glutathione (GSH). GSH has two forms: monomers and dimers, mainly distinguished by the presence of thiol group. Purpose: This study aims to see the difference in interaction between PCT with both forms of GSH. Method: Molecular docking was performed using Autodock Vina 1.1.2 on whole GSH surfaces. The main parameter used was the free energy of binding as affinity marker, as well as the position of PCT toward GSH. Result: The docking results show that PCT has a slightly higher affinity to the dimeric form of GSH than its monomeric form with the free energy of binding -2.7 kcal/mol and -2.2 kcal/mol, respectively. The interesting thing is the acetyl group of PCT is in a position far from the thiol group in the monomeric form of GSH, in contrast to its dimeric form. Conclusion: These results show that difference in affinity of PCT to both GSH forms is influenced by the position of the acetyl group against the thiol group of cysteine in GSH. The proximity of the pro-oxidant group to the thiol group leads to an increase in the affinity of the pro-oxidant to GSH.


This won best undergraduate paper in English. Shakespeare's Romeo and Juliet tells the story of two young lovers who endure chronic gender-specific oppression due to the expectations of Verona's patriarchal society. Both major and minor characters clarify the standard gender roles in the society. In this essay I argue that the pressure imposed by this patriarchy and the perpetuation of these patriarchal values by the families of the lovers eventually leads to the tragic death of Romeo and Juliet. I assert that the death of the lovers is a result of institutionalized sexism and necessity for gender role fulfillment. For this paper I utilize feminist methodology; therefore, I examine the text using a critical technique that involves looking at the oppression of both men and women in the play. I consider symbolic meanings of pertinent aspects of the play, and note how the main characters construct their gender identity. My paper begins with a short introductions and follows in four sections titled; Demonstrations of Verona as Patriarchal, Juliet's Refusal to Conform, Romeo's Inability to Conform, and Tragedy as a Direct Result of Oppression. This paper concludes that both lovers eventually kill themselves because they cannot conform to their gender roles.  I wrote this paper as an assignment for my English Methodology course (ENGL 3000) and continue to work on the text as a point of interest for future research.


Adult male rabbits were subjected to either bilateral vasectomy or a bilateral sham operation. Several portions of the epididymis and vas deferens were studied with the light and electron microscopes at intervals up to 9 months after operation. In vasectomized rabbits, the epididymis and proximal vas deferent were distended with sperm and expanded progressively from 2 weeks through 4 months after vasectomy. This expansion continued in one rabbit killed at 6 months and in one killed 9 months after vasectomy. However, in the remaining 3 rabbits killed 6 or 9 months after vasectomy, the epididymidis and vas deferens were less distended than in other vasectomized animals, and in 2 of these there was evidence that sperm escaped the male duct system and underwent phagocytosis in a spermatic granuloma in the surrounding connective tissue. Despite the distention, the epithelium of the epididymis and vas deferens of vasectomized rabbits remained columnar. The epithelium also continued to be functionally active as indicated by the persistence of the characteristic complement of cellular organdIes, including vacuoles and lysosomes thought to be involved in absorption and smooth endoplasmic reticulum that may be involved in secretion. The epithelium of the cauda epididymidis and proximal part of the vas deferens in both vasectomized and sham-operated animals fixed 2 to 6 months after operation was highly folded and had many apical cytoplasmic projections. The origin of this change is unknown, but it may be related to seasonal variations in activity of the epithelium.


A novel fuel-air mixing technique on the basis of vortex generators has been developed and successfully implemented in the worlds first lean-premix reheat combustor of ABB's GT24/GT26 series industrial gas turbines. This technique uses a special arrangement of delta-wing type vortex generators to achieve rapid mixing through longitudinal vortices, which produce low pressure drop and no recirculation zones along the mixing section. In this paper, after a short introduction to the topic, the motivation for utilizing vortex generators and the main considerations in their design are explained. A detailed analysis of the flow field, pressure drop and the strength of the vortices generated by a single vortex generator are presented as one of the three main geometrical parameters is varied. The results obtained through water model tests indicate that an optimum vortex generator geometry exists, which produces the maximum circulation at a relatively low pressure drop price. Moreover, the axial velocity distribution along the mixing section stays uniform enough to assure flash-back free operation despite the elevated inlet temperatures encountered in a reheat combustor. After selecting this optimized geometry, the process of the arrangement of multiple vortex generators in an annular combustor segment is described. The optimum arrangement presented here is suitable both for gaseous and liquid fuel injection, since it requires only one injection location per combustor segment.


In this study, the purposes are investigating and analyzing car emission factors for estimating road emissions and the legal framework for the control of particulate matters. At the result, when input emission data are not realistic, the modeling output concentration distributions can lead to a serious distortion of the results. So, the spatial analysis of the dust emission vehicles have to be based on the actual traffic volumes. Because dust emission factors used in the car by National Institute of Environmental Research Method (2010) are mainly targeted for 2003-2007 cars these could not reflect the effect of DPF and the dust emission of gasoline passenger car. So, the real dust emission factors of diesel and gasoline cars need to be developed.

My main comment is that given that the original Teq includes the climatological effects of ozone, it would have been nice to see how this version of the model differs. For example, it would have been interesting to compare SCDM with just climatological ozone versus SCDM with interactive ozone and compare the SSW diagnostics. This would have provided some proof-of-concept that interactive ozone can cause differences in SSW evolution, for example.


There is currently a lack of understanding of the deposition profile in a batch atomic layer deposition (ALD) process. Also, no on-line control scheme has been proposed to resolve the prevalent disturbances. Motivated by this, we develop a computational fluid dynamics (CFD) model and an integrated online run-to-run and feedback control scheme. Specifically, we analyze a furnace reactor for a SiO2 thin-film ALD with BTBAS and ozone as precursors. Initially, a high-fidelity 2D axisymmetric multiscale CFD model is developed using ANSYS Fluent for the gas-phase characterization and the surface thin-film deposition, based on a kinetic Monte-Carlo (kMC) model database. To deal with the disturbance during reactor operation, a proportional integral (PI) control scheme is adopted, which manipulates the inlet precursor concentration to drive the precursor partial pressure to the set-point, ensuring the complete substrate coverage. Additionally, the CFD model is utilized to investigate a wide range of operating conditions, and a regression model is developed to describe the relationship between the half-cycle time and the feed flow rate. A run-to-run (R2R) control scheme using an exponentially weighted moving average (EWMA) strategy is developed to regulate the half-cycle time for the furnace ALD process between batches.

Background: The proposed South African coal-fired power project, Kusile, wit h a projected life-span of 50 years, will further lock South Africa into carbon-intensive electricity supply, and, by crowding out investment , undermine the potential for renewable energy development. More importantly, th is power plant is not going to address the energy needs of poor South Africans. S ince the April, 2010 approval of World Bank-funded Medupi (another 4,800 MW) power p lant, the electricity prices have gone up 137%, thus increasing the likelihood of poo r people dropping off the grid. 1


The water condition in cages of the paste of chlorella was investigated by the method of thermogravimetric analysis. With increasing heating rate endothermic effect corresponding to the dehydration process is shifted towards higher temperatures. Temperature intervals of chlorella dehydration are defined at rate of heating 2 К/min - 308-368 K, 5 К/min - 323-403 K, and 10 К/min - 348-403 K. Quantitative characteristics of kinetic unequal water in chlorella have been received for each step (∆, ∆Т, a mass fraction (w), energy of activation (Еа)). This process is similar to the process of the dehydration in ion exchange membranes. The derived kinetic characteristics give the possibility to define an optimum temperature interval and rate of drying microalgae for the purpose of increase of periods of storage in the form of paste or a solid substance for the further use as the bioadditive. In addition the presence of three types of water chlorella in a cell set according to NMR with pulsed magnetic field gradient. Since free water is involved in biochemical, chemical and microbiological processes, it is desirable to remove during drying of the preparation. The resulting temperature range of 323-343 K (step 2) at a heating rate of 2 K / min corresponds to a temperature range of drying the chlorella in a production environment. It should be noted that the highest number of algae in a tightly-water (the last stage). Apparently, this is determined by a unique cell structure. Temperature ranges dehydration process are not clear and vary depending on the heating rate, which is fully in line with previous studies of thermal analysis for grains, vegetables and bakery products.


The internal resonator banjo, patented and first sold by Fred Bacon around 1906, remains something of a cult favorite and is still produced by some independent luthiers. According to enthusiasts, the characteristic design elements produce a sound that is mellower, richer, and of greater complexity and presence than without them. Aspects of that sound are studied here, comparing instruments that are otherwise identical and identifying physics mechanisms that are likely responsible.


To the Editor : I read your editorial answering the letter of Dr. Kenneth Hall in the June issue of the JOURNAL. As a radiologist, I feel that I should correct your statements in the reply. The radiologist does not reverse PA films. The radiographs are taken in a PA projection as a routine, but when placed in the viewing box or reproduced, the cardiac silhouette will appear on the left side of the films or the picture. The technique of taking a radiograph has nothing to do with the way they are examined. In similar ways, one photographic slide is "projected" in a manner that one can see the picture as it is in front of the eyes, and not the way the object or subjects are reflected within the camera.


This experiment was conducted to study the effects of different proportions of organic and inorganic trace minerals on growth performance,and blood biochemical paramenters in broiler chickens. In addition,contents of the trace elements in tissues and serum,and the tibia performance paramenters were investigated after supplementation of organic and inorganic minerals in broiler chickens. A total of 400 one-day-old AA broiler chickens were randomly assigned to 5 groups with 8 replicates per group,and 10 chickens per replicate. The iron( Fe),copper( Cu),manganese( M n),zinc( Zn) of the basal diet was provided with analytical grade iron vitriol,anhydrous cupric sulfate,manganese sulfate monohydrate,and zinc vitriol,respectively. The contents of those trace minerals were Fe 100 mg / kg,Cu 20 mg / kg,M n 120 mg / kg,Zn 120 mg / kg in the basal diet,respectively. There were five groups: group I was fed with inorganic forms of Fe,Cu,M n and Zn,and groups Ⅱ to Ⅴ were fed with different proportions( with 30 %,50 %,70 % and 100 % replacements of the inorganic trace minerals in the basal diet,respectively) of organic trace minerals. The experiment was lasted for42 days. The experimental results showed as follows: 1) feed to gain ratio( F / G) of broiler chickens fed with lower proportions of organic trace minerals( groups Ⅱ and Ⅲ) was significantly lower than that of control group during the periods of 4 to 6 weeks and 1 to 6 week( P 0. 05). 2) Tissue deposition results showed that group Ⅲ showed highest liver Cu and M n contents,and activities of superoxide dismutase( SOD) than the other groups. 3) Group Ⅳ showed significantly increased iron content of serum( P 0. 05). To sum up,replacement of 50 % inorganic trace minerals with organic trace minerals in the basal diet had relatively better effects on growth performance,mineral deposit and SOD activities of broiler chickens.


Abstract : The purpose of this study was to analyze electroencephalographic (EEG) records obtained from heroin dependent individuals during withdrawal. The EEG records were analyzed for various awake and sleep states according to standard techniques. The preliminary results indicate that the control subjects exhibited fairly standard sleep patterns. The patients undergoing heroin withdrawal displayed a definite disruption in the total sleep pattern which was characterized by an increase in the awake and awake plus alpha states, a decrease in some of the slow wave sleep states, and a greater suppression of the REM sleep state.


This paper presents a system for the automatic detection of hypernasal speech signals based on the combination of two different characterization approaches applied to the five Spanish vowels and two selected words. First one is based on classical features such as pitch period perturbations, noise measures, and Mel-Frequency Cepstral Coefficients (MFCC). Second is based on the non-linear dynamics (NLD) analysis. The most relevant features are selected and sorted according to two techniques: principal components analysis (PCA), and sequential floating feature selection (SFFS). The decision about whether a voice record is hypernasal or healthy is taken using a soft margin - support vector machine (SM-SVM). The experiments are carried out using recordings of the five Spanish vowels and the words /coco/ and /gato/, considering three different set of features: (1) the classical approach, (2) the NLD analysis, and (3) the combination of the classical and NLD measures. In general, the accuracy rates are higher and more stable when the classical and NLD features are combined into the same feature space, indicating that the NLD analysis is a complement for the classical approach.


In an attempt to better define molecular influences on rat interstitial collagenase gene expression in cartilage, the promoter function was characterized using transient transfection assay, electrophoresis mobility shift assay, and genetic analysis in isolated growth plate chondrocytes. Data from 5′‐flanking deletion and selected mutations suggest that multiple cis elements in both the proximal and distal regions of the promoter were important in the regulation of promoter activity. A proximal tumor response element (TRE) was shown to be necessary for basal and interleukin (IL)‐1β–inducible reporter gene activity. Cells stimulated by IL‐1β (1 ng/ml; 18 h) had elevated TRE binding activity, and one of the factors involved was identified as the nuclear protein, c‐Jun. Indeed, c‐Jun directed antisense oligonucleotides reduced rat interstitial collagenase mRNA. A sense oligonucleotide was ineffective. Regulation of promoter activity was susceptible to Ras‐dependent signaling as expression of dominant negative mutant of Ras kinase (pZIP‐RasN17) reduced reporter gene activity. In a comparison of proximal promoter reporter plasmid activity between proliferative and hypertrophic cells, inhibition of Ras‐dependent signaling was less effective in the later cell type. This study suggests that the activation of nuclear binding proteins that bind TRE may be a common event with IL‐1β regulation. Moreover, these data suggest that the regulation of rat interstitial collagenase gene expression is a combinatorial process and multiple cis‐acting regulatory sites may interact to exert different effects dependent on the stage of chondrocyte differentiation.

Abstract A reexamination of the holotype frontoparietal of Pelobates praefuscus Khosatzky, 1985 from the Pliocene of Moldova and an investigation of newly referred frontoparietal reveal previously unknown characters for this species. P. praefuscus, considered a synonym of Pelobates fuscus, is regarded here as a separate species. It differs from P. fuscus in the presence of frontoparietal-squamosal contact and medial position of the foramen arteriae occipitalis and from all extant Pelobates in having the arteria orbitonasalis open posteriorly. The last character, previously known only in early Miocene Pelobates, is shown to be present in late Miocene and early Pliocene congeners, whereas in late Pliocene–Pleistocene congeners, the posterior part of the arteria orbitonasalis generally is covered ventrally by bone.


Political awareness is an important feature of every political system. No political system can operate without having the awareness and participation of the people in the political process. Political awareness is commonly known as a process through which people participate in the decision making or policy formulation process of the government. In other words, having interest in politics, exercising voting right, listening to political discussion, attending meetings and holding any political position is called political awareness. Political awareness is beneficial for both the citizens and the state. The stability of any given democracy depends upon awareness and active participation of the citizens. At present, it is a matter of great importance that peoples" awareness in politics is gradually increasing. Like the other parts of Assam, the awareness of the tea tribes" women community is also increasing at Biswanath district in all levels. However, this section of people working in the tea plantations of Assam is one of the marginalized groups of people who remain dominated, deprived and discriminated in various aspects of their day-to-day life. But, proper study in this regard has not recorded about the awareness and participation of the tea tribes women in politics. Therefore, the present paper attempts to study about the degree of political awareness among the tea tribes" women. The present study analyses the mindset of the tea tribes" women in the area of political awareness as well as their interest in the political process.

White-brined cheeses are widely produced in the North-east Mediterranean area and the Balkans. Traditionally, they were manufactured as artisanal cheeses, and nowadays they are manufactured on an industrial scale, and rigorous control of the production and maturation processes is essential. Aspects of the microbiology of white-brined cheeses and their significance with respect to the quality and safety of the final products are discussed in this review.


The paper discusses the problems of implementation of the state anti-corruption policy in the Transbaikal region. The relevance of the effectiveness of the anti-corruption policy is directly connected with the community's confidence to activities of the state bodies at all levels. The anticorruption politics is also an important factor of the successful socio-economic development and development of a political system. The author uses the materials taken from official reports of the state executive bodies that give opportunity of evaluation of the effectiveness of anti-corruption measures. The author identifies problems and contradictions connected with practical difficulties of corruption prevention, gives some recommendations and proposals to authorities. The author gave some critical comments about the situation which help state bodies to evaluate the effectiveness of the implemented anti-corruption measures.


The surge in biodiesel production in recent years has resulted in enhanced research interest in the conversion of glycerol to other valuable chemicals such as glycerol carbonate (GLC). In the present study, the catalytic transesterification of glycerol with dimethyl carbonate (DMC) for the production of GLC was studied with calcium–lanthanum mixed-oxide catalysts at different Ca/La molar ratios. These catalysts were synthesized using an exo- and endotemplating method. The physicochemical characteristics of the catalysts were determined using powder X-ray diffraction (XRD), N2 sorption, scanning electron microscopy (SEM), and temperature-programmed desorption (TPD) of CO2 and NH3. The transesterification of glycerol was found to be highly dependent on the basicity of the catalysts. The catalyst with a Ca/La molar ratio of 3 (3CaLa) showed the highest glycerol conversion and GLC yield. Optimization of the reaction parameters and reusability of the catalyst were studied with the 3CaLa catalyst in terms of gl...


Currently the entire world is struggling against the virulent pandemic COVID-19. Unfortunately, each of us is affected, either directly or indirectly. Our conference, 4th International Conference on Artificial Intelligence Applications and Technologies (AIAAT 2020) was not an exception. In August, mass gatherings are not permitted by the government in China to protect people. It is uncertain when the COVID-19 would end, so it remains unclear for postponement time, while many scholars and researchers wanted to attend this long-waited conference and have academic exchanges with their peers. Therefore, in order to actively respond the call of the government, and meet author's request, the AIAAT 2020, which was planned to be held in Shenzhen, China from Aug. 7 to 9, 2020, was changed to be held on Aug. 8, 2020 online through Tencent VooV software. This approach not only reduces people gathering, but also meets their communication needs.


Conventional explanations of poor African economic performance generally fail to pay adequate attention to causal mechanisms of growth, decline and stagnation. Many African countries experienced investment booms after independence but, in contrast to East Asian newly industrialising economies, these were not sustained owing to failure to establish a virtuous growth circle involving complementary increases in savings and exports. Structural adjustment programmes dismantled stat-mediated mechanisms of accumulation without putting viable alternatives in place, and failed to tackle the structural constraints which impede productivity growth in agriculture. A new policy approach, drawing on the experience of both post-colonial and adjustment periods, is necessary. Copyright 2001 by Oxford University Press.


It is interesting to note that in case the constants dij, dmn, and Cmn can be determined from other molecules, it is possible by means of the two relations together to predict both re and ke for molecules for which no data at all exist.


We consider the problem of gambling on a quantum experiment and enforce rational behavior by a few rules. These rules yield, in the classical case, the Bayesian theory of probability via duality theorems. In our quantum setting, they yield the Bayesian theory generalized to the space of Hermitian matrices. This very theory is quantum mechanics: in fact, we derive all its four postulates from the generalized Bayesian theory. This implies that quantum mechanics is self-consistent. It also leads us to reinterpret the main operations in quantum mechanics as probability rules: Bayes' rule (measurement), marginalization (partial tracing), independence (tensor product). To say it with a slogan, we obtain that quantum mechanics is the Bayesian theory in the complex numbers.


This paper investigates the relationship between air traffic and economic growth in various developing regions and compares it with an "enduring industry fact" of an elasticity around 2 for the developed world. The analysis is conducted from two distinct databases, both with regional aggregates and with country-level ECM estimations. We conclude that there does not seem to be substantial differences in elasticities across the various regions and we show that the introduction of autonomous country-specific time trends leads to a substantial reduction of elasticity estimates.


Tight oil and shale gas reservoirs have a significant part of their pore volume occupied by micro (below 2nm) and mesopores (between 2 and 50nm). This kind of environment creates strong interaction forces in the confined fluid with pore walls as well as between its own molecules and then changes dramatically the fluid phase behavior. An important work has therefore to be done on developing upscaling methodology of the pore size distribution for large scale reservoir simulations. Firstly, molecular simulations are performed on different confined fluids in order to get reference thermodynamic properties at liquid/vapor equilibrium for different pore sizes. Then, the comparison with commonly used modified equation of state (EOS) in the literature highlighted the model of flash with capillary pressure and critical temperature and pressure shift as the best one to match reference molecular simulation results. Afterwards fine grid matrix/fracture simulations have been built and performed for different pore size distributions. Then, coarse grid upscaling models have then been performed on the same synthetic case and compared to the reference fine grid results. A new triple porosity model considering fracture, small pores and large pores with MINC (Multiple Interacting Continua) approach, has shown very good match with the reference fine grid results. Finally a large scale stimulated reservoir volume with different pore size distribution inside the matrix has been built using the upscaling method developed here.


T the half century or more in which American sociology has de veloped, various students in the field exhibited an interest in the field of edu cation. In the early decades of this century, several sociologists sought to develop an applied educational.sociol ogy. Some of these saw sociology as the field which would provide education with goals or ends which envisioned better society. Lester F. Ward thought of education as the ameliorative institu tion, and much of his sociology was concerned with pointing the direction of social improvement. In contrast with some of his predecessors and contem poraries, Ward recognized the process of social change and considered public education the primary means of direct ing change for the benefit of society. Iliis conception of education was in harmony with and reinforced the sig nificant American values associated with progress. Many educators, draw ing heavily upon the contributions of such early thinkers as Ward, have adopted the philosophy that education is the molder of society and director of social change. Growing out of the belief that edu cation is a means of social change, several sociologists have sought to use their discipline to define the goals to ward which education should strive. Current thinking among sociologists, however, generally assumes that the norms of the society as a whole will set the direction of social change. In fact the goals and direction of an educa tional process can only be defined in the social system within which it func tions. Increasingly, however, sociolo gists and other social scientists may as sist in determining the means by which the goals of education may be achieved most efficiently. By this we simply mean that, given certain goals, the so cial scientists' analyses may identify the social processes by which certain goals may or may not be achieved. The analysis may indicate that some arc be yond reach, and others may be achieved only with costs to the society that it is not in a position to pay. Some sociologists arc currently examining the ways and means by which society may, or may not, be changed through edu cational efforts. Sociologists have little


Abstract We have identified ~500 relatively relaxed galaxy clusters at low redshift (z < 0.3) from the maxBCG catalog with double radio lobes at the center; about 200 radio counterparts of brightest cluster galaxies (BCGs) of these clusters appear to be wide-angle tailed (WAT) radio sources, indicating ongoing interaction between its host galaxy and the surrounding ICM. Our analysis suggests that the radio power of WAT is positively correlated with the optical luminosities of host BCGs, and increases with redshift; whereas the cluster ellipticity-radio galaxy fraction relation shows no obvious difference between WAT and non-WAT clusters.

Caribbean Basin Economic Recovery Expansion Act of 1989 - Title I: Amendments to the Caribbean Basin Economic Recovery Act and Related Provisions - Subtitle A: Amendments to Caribbean Basin Economic Recovery Act - Amends the Caribbean Basin Economic Recovery Act (the Act) to repeal the termination of duty-free treatment of beneficiary countries. Requires the United States Trade Representative (USTR) to establish with each beneficiary country guaranteed access levels for textile products assembled in such country from qualifying fabrics (fabrics formed and cut in the United States and certain fabrics of foreign manufacture which are cut in the United States). Authorizes the USTR to negotiate a bilateral agreement with each beneficiary establishing such guaranteed access levels. Makes such products eligible for duty-free treatment. Provides that textile products assembled in a beneficiary country from qualifying fabric, incorporating findings and trimmings of foreign origin, are eligible for guaranteed access and duty-free treatment if such findings and trimmings do not exceed 25 percent of the cost of the components of the assembled product. Expresses the sense of the Congress that: (1) the benefits granted through the establishment of guaranteed access levels in bilateral textile agreements should not result in any disadvantage to U.S. firms that seek export certificates or export visas which authorize shipments under specific limits; and (2) the USTR should obtain assurances from beneficiary countries which have been granted guaranteed access levels that such countries will administer export certificates or export visas in such a manner as to ensure fairness and nondiscriminatory treatment to such U.S. firms that seek allocations under specific limits rather than guaranteed access levels. Declares that each quota article (any textile or apparel article that is imported under either a specific limit or a designated consultation level established in a bilateral textile agreement with a


Deacidification of fruit extracts is necessary in certain situations which include consumer preference and product application. Although deacidification of noni extract using ion exchange resin and calcium carbonate addition has been reported, comparison between the two methods is lacking. This study was conducted to compare the effects of different deacidification treatments of ion exchange resin and calcium carbonate on the properties of noni extract. Ion exchange resin (Amberlite IRA-67) (R), calcium carbonate addition (CC), ion exchange resin followed by calcium carbonate addition (RC) and calcium carbonate addition followed by ion exchange resin (CR) were used to deacidify noni extract. Subsequently, analysis for pH, total soluble solids (TSS), total phenolic content (TPC), free radical scavenging ability (DPPH) and ferric reducing power (FRAP) were carried out. Compared to control, TPC, DPPH, and FRAP of noni extract decreased significantly (p<0.05) after deacidification using all different treatments. pH increased significantly (p<0.05) for all samples. TSS decreased significantly (p<0.05) after deacidification using all different treatments except for samples using resin (R) and calcium carbonate (CC). Deacidification using resin (R) produced a higher pH but lower TPC, DPPH and FRAP compared to calcium carbonate (CC). Ion exchange resin followed by calcium carbonate (RC) produced a lower (p<0.05) DPPH compared to calcium carbonate followed by ion exchange resin (CR). Deacidification of noni extract using calcium carbonate (CC) was the best method as it produced the smallest (p<0.05) reduction per change of pH for FRAP and no significant difference for DPPH compared to ion exchange resin (R).


With each successive technology node the overlay specifications of the immersion lithography scanner have become increasingly more stringent. One of the challenges is high order distortions introduced by the mask. These distortions may contribute significantly to the product overlay budget raising it above the specification requirements and are not easy to correct. The higher order distortions, originating from pellicle and mask process imperfections, have been shown to result in errors in the range of several nanometers to the overall overlay budget [1],[2]. Correction markers and the actual product features cannot occupy the same space on the mask. As a result they might be exposed to differing local distortions which could result in non-optimal systematic distortion corrections [3]. Therefore high precision placement measurements of features across the mask are required for placement control and correction. The Applied Materials Aera2TM aerial imaging mask inspection system is capable of generating high precision global and local feature placement maps with a high measurement density. These maps can be used to monitor feature placement. Furthermore, the maps can be used in a feed forward APC system such as ASML's GridMapper IntrafieldTM[4]. This feed forward system helps to reduce the overall overlay error of feature processes and to meet the stringent overlay budget requirements. In this paper we present for the first time (?) mask registration results obtained with the Aera2 and show that this tool is able to meet the 1 [nm], 3δ ITRS requirement [5] for the 22nm node. Key words: Inspection, Mask, Reticle, Placement, Registration, Overlay,


To unravel the dominant cause of the weak emission line in a subset of optically selected radio-quiet 'weak emission line quasars' (WLQs), we have investigated the possibility of an underdeveloped broad line region (BLR). For this, we have modeled spectral energy distributions (SED) of 61 WLQs by using their optical and infrared (IR) photometric observations from SDSS and WISE respectively. SED fit consists of various emission components, including the luminosity from the dusty torus ($L_{tor}$). For comparison with the normal quasar, we have used a control sample of 55 QSOs for each WLQs matching in emission redshift and SDSS r-band. Based on our measurement of $L_{tor}$, we found a decrement of $42\pm2$\% in IR-luminosity in WLQs w.r.t the control sample of normal QSOs. Using $L_{tor}$/$L_{bol}$ as the measure of torus covering factor ($CF_{tor}$) we found a similar decrement in WLQs covering factor, with their $CF_{tor}$ distribution being significantly different w.r.t. the normal QSOs with a KS-test $P_{null}$ of $4.27 \times 10^{-14}$. As dusty torus and BLR covering factors are expected to be of a similar order in AGN, our results suggest that the BLR in the WLQs is underdeveloped and could be a dominant cause of the weakness of their emission line. As a result, our analysis gives support to the models of WLQs based on the evolution scenario being in an early stage of AGNs.

PURPOSE: A method for transceiving continuous schedule change information and an apparatus thereof are provided to efficiently change a base station location when allocated resource area is shared to an existing terminal traffic. CONSTITUTION: A base station transmits a UL(UpLink) basic allocation A-MAP(Mobile Application Protocol) IE(Information Element) to a terminal(S210). The terminal transmits UL data by using the resource allocated by the UL basic allocation A-MAP IE(S220). The terminal transmits the UL data through the resource allocated by continuous scheduling(S230). [Reference numerals] (AA) Terminal; (BB) Base station; (S210) Allocating a resource of a UL Basic Assignment A-MAP IE in a sub frame in which a resource is allocated by long cycle persistent scheduling; (S220) Transmitting uplink data by using a resource which is allocated in the UL Basic Assignment A-MAP IE; (S230) Transmitting uplink data through a resource allocated by long cycle


The theory of compressive sensing (CS) has inspired the concept of a compressive direction-finding (DF) antenna array where N antenna elements are combined into M measurements before sampling with expected performance similar to that of a conventional N-element array, given that the number of directions of arrival (DoAs) is sufficiently small. The use of random Gaussian sensing matrices in designing such an array has previously been proposed. The use of codebooks with numerically optimised coherence in designing a compressive array is proposed as an alternative, and is shown to result in better performance for a system with few receivers.


. Blasting activities carried out by PT. Bintang Sumatera Pacific produces quite large> 60 cm (> 15%), while the bucket capacity of Hitachi Zaxis 200 digger is 1.09 m3 in size. Blasting geometry is one of the factors causing the large amount of fragmentation produced. So the blasting fragmentation analysis was carried out using the kuz-ram equation and the blasting geometry improvement was done using R.L Ash and C.J. Konya. As a result of the research the following conclusions were drawn. First, rock fragmentation from the proposed blasting geometry, the average fargmentation of the rocks that passes is <60 cm in size with split desktop software, which is 100% of 1 blasting. Second, based on calculations using the RL Ash formula for the proposed blasting geometry I, II, III, IV and calculations using the CJ Konya formula for the proposed blasting geometry V. Then the blasting geometry proposal I is selected using the RL Ash formula with a space value (S) of 2 meters, burden (B) 2 meters, depth (H) 5.5 meters, height (L) 5 meters, Stemming (T) 2 meters, Subdrilling (J) 0.5 meters, average filling column 3.5 meters. Third, the production yield obtained from one trial of proposed blasting is 5977 tonnes.


We report inelastic neutron scattering measurements of the phonon spectra in a pure powder sample of the multiferroic material BiFeO3. A high-temperature range was covered to unravel the changes in the phonon dynamics across the Neel (TN ∼ 650 K) and Curie (TC ∼ 1100 K) temperatures. Experimental results are accompanied by ab initio lattice dynamical simulations of phonon density of states to enable microscopic interpretations of the observed data. The calculations reproduce well the observed vibrational features and provide the partial atomic vibrational components. Our results reveal clearly the signature of three different phase transitions both in the diffraction patterns and phonon spectra. The phonon modes are found to be most affected by the transition at the TC. The spectroscopic evidence for the existence of a different structural modification just below the decomposition limit (TD ∼ 1240 K) is unambiguous indicating strong structural changes that may be related to oxygen vacancies and concomitan...


A special double cannula used with a seal at the cervix to create a negative pressure in the uterine cavity to aspirate samples of endometrial cells and/or tissue fragments is described. The negative pressure closes the fallopian tubes so that the lavage solution does not enter the abdominal cavity. About 30 ml of normal saline are used. The equipment is sterile and disposable. The procedure is rapid well-tolerated and complications have not been reported. In a series of over 1000 specimens obtained with this equipment 69 were positive for endometrial carcinoma. Curettage confirmed the diagnoses in 53. There were no false negatives. Papanicolaou stains were done for 35 of the 53; only 9 (26%) were positive. In another study of 1500 patients with symptoms the overall accuracy for detection of endometrial carcinoma with this equipment was 93%. In another clinical trial of 107 cases results obtained with the washer agreed with D and C in 101 cases. The method may be used as a part of the routine pelvic examination in women over age 45.

Taiwan is the only major economy which does not publicly release information about its central bank's intervention in FX derivative markets. This paper seeks to provide a simple but tricky to prove solution to this enigma: The Central Bank of the Republic of China is conducting one of the world's largest FX derivative interventions, as of mid-2018 amounting to ∼USD 130bn, or 20% of Taiwan's GDP. Structured as FX swaps, conducted with and intermediated by the local banking system, the ultimate counterparty to such transactions is Taiwan's rapidly growing life insurance industry, seeking FX hedges for the vast amounts of household savings it has directed into USD-denominated fixed income markets.


Commercial tea culture in Turkey is carried out in an area of 76800 ha in the provinces of Rize, Artvin, Trabzon, Giresun and Ordu located in the Black Sea region. A large part of the tea production area as a percentage is concentrated in Rize province (65%), followed by Trabzon (21%), Artvin (11%) and GiresunOrdu (3%). Tea is an economically valuable plant for the region and a means of subsistence for more than 200,000 farmers. In the provinces, 37%, 10%, 7% and 2% of the population of Rize, Artvin, Trabzon and Giresun respectively engage in tea growing. Therefore, tea plants cover a considerable part of the agricultural fields in these provinces. For example, 95% of the agricultural fields in Rize are allocated exclusively to tea cultivation (Anonymous, 1997). Almost all tea gardens are established with plants from seed origin. Continuous seed propagation since 1920 has produced populations with different yield and quality properties reflecting a wide genetic variation.

The fine structure of crypt epithelium in human palatine tonsils was studied by scanning electron microscopy (SEM).The tonsils were obtained from patients with chronic tonsillar infection. Immediately following tonsillectomy, the tonsils were puncture-perfused with glutaraldehyde fixatives. By this procedure, blood and tissue fluid were eliminated from the tissues. Specimens were freezecracked and the inside structure of the epithelium was exposed for examination by SEM.Crypt epithelium was classified into three types according to the three-dimensional structure. Type I epithelium: It was stratified squamous epithelium. In the basal and intermediate layers, intercellular space of the epithelial cells formed a network of canalicules, which were considered as passages for infiltrating cells.Type II epithelium: Epithelial cells were polygonal in appearance and possessed several cytoplasmic processes, by which they were connected with each other to form a meshwork in this epithelium. A large number of infiltrating cells were observed in the meshes of the epithelial cells, showing the state of "lympho-epithelial symbiosis". There were "cryptal micropores" in the surface layer, and they communicated the cryptal lumen to the network structure of the epithelium. It was suggested that the cryptal micropores might represent passages for infiltrating cells and various antigens.Type III epithelium: This epithelium showed a destruction of the superficial layer and marked cell infiltration. There were a lot of collagen fibers, several blood vessels and a few squamous epithelial cells in the epithelium. It was suggested that the construction of this epithelium was caused by chronic inflammation.Based on these results, it revealed that the type II epithelium was playing an important role in the immunological activity of the tonsil.

Purpose

– This article discusses the impact of electronic resources on the suite of services provided by serials agents.

Design/methodology/approach

– The article describes the changing needs of academic libraries in this new environment, and the ways in which serials agents can repurpose themselves to remain a corner‐stone of serials management. A white paper by R2 Consulting is referenced for its insights into the expectations and requirements of academic libraries. Brief statements by two Otto Harrassowitz executives are included.

Findings

– If agents are to take on these new responsibilities for e‐journals, libraries must expect to pay something beyond typical service fees. Many cash‐strapped libraries will find it difficult to pay higher fees to agents than they do presently, even for services that could save hundreds of hours per year in staff time. Consortia‐purchased collections and the proclivities of a handful of large publishers aside, it will no doubt become necessary for libraries to entrust all subscriptions to agents as the majority of subscriptions maintained by libraries migrate from print to electronic.

Originality/value

– Outlines a role for serials agents in the new digital information world.


Diabetes Mellitus (DM) is a gathering of metabolic sicknesses described by hyperglycemia that happens because of deformities in insulin discharge, insulin action or both. One of the actions to treat diabetes mellitus nonpharmacologically is by a decoction of Moringa leaves. This review means to decide the impact of bubbled Moringa leaves on glucose levels in patients with type II diabetes mellitus. The plan of this exploration is Quasi Experiment with Two Group Pretest Posttest Design. The samples were 16 patients with Type II DM which were divided into 8 people in the intervention group and 8 people in the control group. The intervention group checked blood glucose levels every day before and after being given Moringa leaf decoction. the intervention group was given a dose of Moringa leaf decoction once a day for 7 days. The control group checked blood sugar levels every day. After 7 days, the glucose levels in both groups were measured and the average glucose levels were compared between the two groups. Data analysis using independent t-test. The results of the t-test statistical test in the intervention group with p = 0.000 (p 0.05) mean that there is a significant effect on the results of blood sugar levels in the intervention group. The conclusion is that there is an effect of boiled Moringa leaves (Moringa oleifera) on glucose levels in patients with type II diabetes mellitus. It is hoped that the results of this study will become input for the Andalas Padang Health Center in providing non-pharmacological therapy of Moringa leaf decoction to diminish glucose levels in patients with type II diabetes mellitus.


Case report A 75-year-old woman was referred by her GP with a month history of slight blood-stained vaginal loss. This was the first episode of bleeding since the menopause. She had had two vaginal deliveries and was sterilised following the second one. Significant history included hypertension, raised serum cholesterol and epilepsy. She underwent a hysteroscopy and endometrial sampling. The histopathology showed dissociated epithelial fragments. There was nuclear hyperchromasia with nuclear membrane abnormalities. The site of origin of the epithelium was not clear. An ultrasound scan revealed a normal endometrial thickness and small fibroids but no adnexal mass could be visualised. She was advised to come back in 6 months time for a repeat ultrasound. Unfortunately, the scan showed a right adnexal solid mass 66 3 cm. The CA125 was within normal limits. Because of the persistent vaginal bleeding and discharge and the right adnexal mass, the patient was advised to have a laparotomy. The findings were a normal-size uterus with a small intramural fibroid in the posterior wall. Both ovaries and the left tube appeared normal but the right tube was distorted in shape forming a mass of 76 56 5 cm. The fimbrial end of the fallopian tube was recognized at one end of the swelling. The outer surface of the swelling was smooth, with no tumour deposits. We performed a total abdominal hysterectomy and bilateral salpingo-oophrectomy and in addition an infracolic omentectomy and peritoneal washings. Histology showed a high-grade malignant mixed Mullerian tumour of the right fallopian tube. Peritoneal washings did not show any malignant cells. She made a good recovery after her operation. This case was discussed at the multidisciplinary team meeting and no adjuvant therapy was planned.


We theoretically and empirically explore the interaction between repurchases and insider trading as signaling devices about private information on firm valuation. Our theory predicts that repurchases, when coupled with insider buying, further the signal of firm undervaluation; insider selling signals the opposite. We find that for the following quarter, repurchases generate 1.2% abnormal returns on average, while repurchase with net insider buying generate 3.7% abnormal returns, an increase of 2.5%. While coupled with insider selling, the abnormal returns are not discernable, implying strong negative insider seller effects. The implications that insider trading augments or attenuates the signal sent by share repurchases.


It is demonstrated that the index of dissimilarity (D), the most commonly used measure of residential segregation, is generally sensitive to the effects of population composition. D is independent of proportion black in an extreme case considered by Duncan and Duncan, but is a logarithmic function of proportion black in two other extreme cases. In the general case, D is in most instances sensitive to compositional changes. It is suggested that the nature of residential succession, in particular the relative stability of the white and black population distributions, influences changes in D. The trend in segregation in Cleveland, Ohio, between 1910 and 1970 is examined in the light of these findings. The properties of a range of other segregation indices are reexamined, and compared with those of D.


Abstract The shielding and indirect spin-spin coupling tensors are calculated for HCN, HNC, CH3CN, and CH3NC, using large atomic basis sets and multiconfiguration wavefunctions that contain the most important correlation effects. The isotropic and anisotropic components of the tensors are compared with experimental data. Deviations between the calculated and experimental results appear to be largely due to vibrational and solvent effects.


Abstract : Processing of columbium alloy sheet panels is complete except for sheet flattening. Two 8 inch diameter ingots of the X-110 alloy were converted by extrusion and rolling to 28 inch wide sheet at three gages 0.020, 0.040 and 0.063 inch. Initial evaluation of the sheet has indicated satisfactory gage uniformity and flatness. Target tensile properties were obtained in the 0.040 and 0.063 inch sheet, but high temperature strength of the 0.020 inch sheet was some 20% lower than obtained in the thicker gages. (Author)
