In the first half of twentieth century,the Hamitic Hypothesis seemed to override the whole academic area of African studies in the Western World.The theory based on racial supremacy became popular at that time just because of rooting on the western traditional racial idea,and in turn had an affect on the racial concepts and relationship of western people,especially on their views on African races and civilizations.No matter in what purposes those scholars created and advocated the Hamitic Hypothesis,the pseudo-theory,in effect,made it publicly accepted that black people in Africa is barbarous and laggard.We should not only reflect on the racism but also take precautious against being trapped in the new theories of cultural determination that have taken place of the Hamitic Hypothesis when discussing African races and civilizations..

Since 1990s,with the long-term recessionary on Japan economy,Japan finance became difficult gradually,the infrastructure invest obviously shortage. At the same time,the third party organization operated failure,which forced Japanese government to seek for new organization format and operation mode on infrastructures,so with this background,Japanese government began to push the development of PFI industry actively. Just in 10 years time,Japan's PFI industry increasingly progressed grandness,and has formed normative management system which includes four sectors,such as project advance,fund sustain,project supervise and specialty consult. The research on the development course and management system of Japan's PFI industry could give our government some direction and reference to promote PFI industry of China.


CIC-2. a member of the CIC family of chlonde channels. has been suggested to be able to functionally compensate for CFïR. However, mechanisms underlying the regulation of C1C-2 activity remain unclear. Purified. reconstituted CIC-2 exhibits constitutive channel activity. suggesting that purification may remove regulatory proteins. It is our hypothesis that CIC-2 interacts with and is regulated by cytoskeletal proteins. Interacting proteins were eluted from a purified CIC-2 column, and western blotting and MALDI-Tof analysis confirmed the presence of actin and dynein. respectiveiy. Functional studies in Xenopus oocytes indicate that these interactions are functionally important. Following treatment with cytochalasin D or EHNA, a dynein inhibitor, there was an increase in CIC2 mediated currents. Our studies indicate that CIC-2 interacts with actin via its Nterminus and that the interaction is sensitive to ionic strength. Cellular fractionation studies suggest that dynein may play a role in the movement of ClC-2 between cellular cornpartments.

An experimental investigation of the interference from signals of ultra wideband impulse radio (UWB-IR) to the existing wireless local area network (WLAN) systems is described. Transceivers of WLAN systems such as IEEE 802.11 b/g were emulated by a signal generator and a signal analyzer programmed by emulation software. UWB-IR signals were generated with an arbitrary waveform generator or a pulse forming network. They were connected with coaxial wires and UWB-IR signals were inserted with an analog signal combiner. The interference was estimated using the error vector magnitude. The effectiveness of a band pass filter to suppress the interference was also demonstrated.


In view of low recognition rate of single-view and complexity of multi-view algorithm,a research was conducted examining the gait recognition under dual-view.Current research on the contour characteristic of the human body in frontal view and the dynamic characteristics of human walking in side view was examined using the complementary features of the gait information under multi-view.Also the gait sequences were obtained utilizing the two views respectively,and then preprocessed to obtain simply connected body silhouettes.Next,the Procrustes mean shape was extracted from the front view,and the active energy images(AEI) was calculated by side view.However,each of the AEI was projected to a low-dimensional feature subspace via two-dimensional local preserving projections(2D-LPP).The final recognition result was obtained by fusing recognition results of two perspectives.The experiments in CASIA dataset(Dataset B) obtained a high recognition rate and achieved the expected effect of recognition.


A t the end stage, patients with heart failure (HF) may require cardiac transplantation. In the acutely ill patient, during bridge to transplantation circulation support, and in the postcardiac surgical intensive care unit, measurement of cardiac output (CO) using thermodilution via a pulmonary artery catheter guides therapy. Noninvasive devices have been designed but have not been widely accepted because of their unproven accuracy and reliability in clinical settings. The Ultrasonic Cardiac Output Monitor (USCOM; Uscom Ltd, Coffo Harbour, New South Wales, Australia) is a 2-dimensional independent continuous wave Doppler device designed for serial assessments of rightand left-sided CO as an alternative to the pulmonary artery catheter. The CardioWest (Syncardia, Tucson, Ariz) is a Food and Drug AdministrationYapproved, biventricular, orthotopic total artificial heart (TAH) that generates a simulated normal flow to the TAH in patients with intractable HF awaiting a heart transplant. This study compared agreement of USCOM hemodynamic measures with those obtained from the computercontrolled CardioWest TAH in patients with HF and assessed the feasibility of USCOM use in this difficult-to-study group. A total of 508 paired measures were made using USCOM at 18 examinations performed on 7 unintubated patients with HF treated as a bridge to transplant with the CardioWest TAHs. Cardiac output, stroke volume (SV), and heart rate (HR) were measured in a blinded fashion while flow was varied using the CardioWest controller. CardioWest values were recorded serially while simultaneous USCOM Doppler flow profiles were obtained and stored to the hard drive of the device. Cardiac output was varied to create a range of outputs. Agreement was determined by Bland-Altman analysis. The mean CO by CardioWest was 7.33 T 0.46 L/min, and by USCOM, 7.34 T 0.51 L/min. Mean SV values were 56.2 T 3.8 mL and 56.6 T 3.8 mL, respectively, and HRs 131 T 3 and 130 T 4 beats/min, respectively. Mean differences among the 18 paired CO, SV, and HR results by CardioWest and USCOM werej0.01 T 0.23 L/min,j0.34 T 1.97 cm, and 1 T 2 beats/min. Respective mean percentage differences among paired measures were j0.3%, j0.6%, and 0.7%, and the percent limit of agreement was 6.4%, 7.1%, and 3.6%, respectively. These results indicated that no clinically important differences were found between USCOM and CardioWest measurements. Based on the excellent agreement between the 2 devices, USCOM is a feasible and accurate method for noninvasive measurement and monitoring of CO in TAH HF patients. The device could be applied to diagnostic and therapeutic applications in circulatory management.

Abstract NiMo sulfide combined with an acidic HY zeolite constitutes a bifunctional catalyst which may be used in alkane hydroconversion. In this work the distribution of Ni and Mo ions loaded in two HY zeolites (HY-3 and HY-17, with Si/Al = 3 and 17, respectively) is examined by transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and N 2 adsorption. With zeolite HY-3, all the Ni but only half the Mo is found inside the grains, mainly in the cavities; MoO 3 microcrystals are observed outside the grains. Sulfidation transforms the outer part of the MoO 3 crystals into MoS 2 , but small MoS 2 -like particles (7 to 15 nn long, 3 slabs thick) are also detected inside the zeolite, mostly in the secondary pores. No significant migration of Mo occurs, but only 50% of the Ni is retained in the sulfided zeolite. Zeolite HY-17 is able to accommodate all the Ni and Mo ions, mainly in the large mesoporous volume. Sulfidation evicts 50% of Ni and ca. 30% of Mo from the zeolite particles. Again, MoS 2 -like entities (30 to 40 nm large, 6 to 10 slabs thick) are observed inside the grains. The dispersion of the NiMo sulfide in the HY-17 zeolite appears to be higher than in the HY-3 support. The NiMoY catalysts were evaluated for the simultaneous hydrogenation of benzene and hydroconversion of n -heptane. Owing to the good dispersion and accessibility of the NiMo sulfide, the zeolite catalysts are as active as NiMo/Al 2 O 3 for hydrogenation. This hydrogenation activity, however, is unable to impart an adequate selectivity in hydroconversion of heptane.


A major concern to engineers engaged in the design of timber harbor structures is protection against marine borers. These pests can severely damage these structures in a relatively short time. Attack is concentrated on submerged timbers in the area between the mudline and the water surface. The intensity of attack is dependent on a number of environmental conditions. The most destructive and widely distributed borers are the Teredinidae and the Limnoria. Some forms of borers exist in all oceans. This paper describes the manner in which the borers destroy timber. It summarizes information gathered by various investigators on the conditions which have bearing on the presence of borers and the factors governing rate of destruction. Several methods of protecting timber structures from infestation are described and the costs compared.

Automated mission planning is one of the key components of an autonomous UAV. The software validation and verification for such decisional autonomy functions is a challenging problem. The software component includes the closed loop vehicle control as well as environment perception. As this is a safety-critical software component, it is important that this software works safely and within projected performance boundaries. This paper discusses the verification and validation approach for the sampling-based mission planner of an unmanned rotorcraft. A layered test strategy is presented, which utilizes different testing methods that complement and build upon each other. Its strengths as well as the possible improvement directions of this approach are discussed. An emphasis is given on automated software-in-the-loop simulations. The approach additionally utilizes benchmarks to assess the implementation performance and real time properties. Finally, to be able to assess the overall test quality, a set of different scalable test abstractions (SUT size, test effort, level of automation, coverage, test complexity and feedback time) is used to analyze the presented strategy.


Adramatic upsurge in people's interest in the many values of wetlands ( 6 ), which at one time were thought to have little or no value ( 1 ), prompted the Fish and Wildlife Service (FWS) in 1974 to undertake a national wetlands inventory ( 9 ). The agency's previous inventory, conducted in 1954 ( 13 ), employed a rudimentary system of 20 classes designed primarily to evaluate wetlands for use as waterfowl habitat. The inventory begun in 1974 produced a new classification system useful to a variety of natural resource disciplines. That new classification system evolved slowly, becoming the product of extensive peer review, comments from state and federal agencies, field testing, and use during the early phases of the inventory.

What is a wetland?

Wetland refers to a portion of the continuum from terrestrial to aquatic sites.The concept varies among individuals, dis-ciplines, and government agencies. Tradi-tionally, wetland has been defined in terms of hydrology, soils, and vegetation. The FWS definition, for example, begins with a general statement about hydrology: "Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water …


ABSTRACT Due to insufficient historical accounts of the north-eastern region of Siam (modern-day Thailand) during the nineteenth century, the landscape, settlement and land use in this area are only vaguely understood. This article thus analyses and interprets the region's settlement and land use by employing a unique nineteenth-century poetic source, the famous Nirat Nongkhai, a classic Siamese 'journey-poem' (nirat), composed in 1875. The poem effectively represents an account (i.e. journal) of a military expedition from Bangkok to the north-eastern region to suppress the Haw people. The poet wrote Nirat Nongkhai with great attention to detail and the key purpose of turning it into an historical travel archive. The poem was framed in the realist style, so it is particularly valuable for the study of landscape. Thus, it helps to clarify settlement and land use characteristics in the region during the late nineteenth century. The settings and contexts of Nirat Nongkhai show that geographical factors were the prime reasons why most of the flat areas remained unused, dry grasslands. Conversely, the low hills were inhabited. The essential settlement pattern was thus one of 'island villages' dispersed over waterside hills, mirroring the basic pattern of forested land (the pa khok) on the hills and river levees. Nirat also demonstrates that topography proved problematic for travel. For these reasons, communities remained largely impoverished and isolated from other regions of Siam.


The number of Kekule structures is an indicator of the aromatic character of the underlying polybenzenoid. Graphite is a polybenzenoid. In this paper, a new algorithm is proposed for determining the number of Kekule structures in rectangular graphite and its incomplete and defective variants. Defective patterns model functionalized structures. Moderate functionalization will cause a slight increase in the aromatic properties of the underlying patterns.

Because of the huge scale and numerous components, a massive database system's availability has become a serious challenge. Many database replication technologies are used to increase the MTTF, but few are provided to decrease MTTR in massive database systems where the traditional backup methods are not feasible for expensive human cost. Based on analyzing the characteristics of the data in massive databases, we propose a novel approach called Detaching Read-Only (DRO) mechanism and its variation DRO+. It decreases MTTR through reducing the size of physically changing data in every database by detaching data on node granularity. The analysis and experiment results show that our approach can not only reduce MTTR by an order of magnitude, but also reduce the expensive human cost without extra hardware cost.


The Dark Social: Online Practices of Resistance, Motility and Power explores the way that users engage online by managing the capacity for anonymous communication in encrypted, hidden, or otherwise obscured online spaces. Scholarship on the Darknet and Dark Social Spaces tends to focus on the uses of encryption and other privacy enhancing technologies to engender resistance acts. Our provocation is that such practices are reflective of emerging data cultures. Here, the usual characterization of dark social spaces are by privacy enhancing technologies that facilitate oppositional acts, division and eva-sion. As a consequence, the actors using these technological affordances are commonly identified as subcultural groups, activists, marginalized cultures and communities, trolls and socially divisive. These are actors who seek to evade, refuse and/or disrupt institutional power. We want to suggest, however, that this approach creates an artificial binary positioning of a fringe of radical actors against institutions of governance, regulation and control. Similarly, approaches that distinguish between social agency and technological affordances protecting digital privacy, on the one hand, and institutional regulation and centralized surveillance on the other, do not acknowledge how powerful institutional actors use these decentralized technologies to reinforce their authority and control. This special edition emerges from a selection of papers presented at the Dark Social Spaces symposium which was held during 2019 at Deakin University in Melbourne, Australia. The intention of the event was to provoke critical examination of dark social spaces. Our purpose during the symposium was to grapple with Darkness for how it might work as the nomenclature for the theoretical, empirical, creative methodological approaches to better understand engagement in dark social spaces. We questioned Darkness as a category, a space, a socio-historical moment, an ontological structure to make sense of what users do in encrypted places online. Workshop participants mapped communicative actions and the users themselves within liminal, interstitial spaces. We were moved to give critical consideration to the complex notional layers of visibility – versus invisibility – and the associated assumption that being visible usually equates with being seen. By extension being invisible or unseen requires vigilance. In doing so, we drew upon issues of contemporary surveillance and the typical language of the governers


Effects of Ca/Pb co‐doping on structure, ferroelectric, dielectric, and magnetic properties of BiFeO3 ceramics are investigated. A structure transition from a rhombohedral phase (space group R3c) to a cubic phase (space group Pm 3¯ m) with the increment of Ca/Pb concentration is revealed by X‐ray diffraction and Raman spectra. In order to compensate the valence change caused by Ca2+ dopant, Pb ions present tetravalent state under the existence of Ca ions. The room‐temperature ferroelectric behavior depends upon Ca/Pb co‐doping and the structural transition in BiFeO3 ceramics. Meanwhile, the variation of the dielectric loss tangent in the frequency range of 102–107 Hz and the leakage current at room temperature illustrate that Ca/Pb co‐doping increases resistivity and reduces leakage current. Compared with that of Sr/Pb co‐doping, the co‐doping of Ca/Pb has improved the leakage current by two orders of magnitude, besides further increasing the ferroelectric polarization and dielectric properties under the same co‐doping concentration. In addition, enhanced ferromagnetism is observed with the increase of Ca/Pb content, which can be attributed to the effective suppression of spiral cycloidal spin structure and spin canting resulting from the structural transition.


The main objective of the study was to explore how teachers teach reading comprehension to Grade 3 Tshivenda-speaking learners. This qualitative study was prompted by the low levels of reading amongst these Grades 3 learners in South Africa. Three schools, each with two Grade 3 classes, were selected in this study. Data from individual interviews with teachers, focus group interviews and classroom observations revealed that there were a number of factors that contributed to the Grade 3 learners' poor performance in reading comprehension. It is recommended that teacher education programmes should be improved and that Tshivenda reading resources be made available, as these are currently extremely limited. The study also indicated that the best way to teach reading comprehension is by teaching learners a variety of strategies that they can use in order to self-regulate their comprehension when reading.

Wheat beer was produced from wheat malt (accounting for 40% of the raw material) by top fermentation yeast. The pilot scale production technology of wheat beer by top fermentation was studied in the 50 ton fermentation tank. The production technology and quality control standard were also introduced in detail. It was proposed that the proper choice and proportion of soft wheat malt with low-protein content and white color skin, high-quality barley malt, rice, and hop provided reliable guarantee for the flavor and quality of wheat beer. The double-mash infusion mashing was easy and practical for wort production. The processing parameters, including inoculation amount, inoculation temperature, main fermentation temperature, and fermentor pressure, were adjusted properly to improve the flavor and quality of wheat beer. The stability test of the end product was satisfied. Therefore, the wheat beer processing technology was basically determined.


In the present study swiss mice received the drug Ro 7-1051 (N-Benzyl-2-Nitro-imidazolacetamide) before infection with the Colombian strain of T. cruzi and results were compared with infection with the same strain but with treatment on the 7th day. Evaluation was performed by means of parasitemia, xenodiagnosis, inoculation in new-born mice and histopathological finfings. Results were better (55.5% of negatives) in pretreated animais as compared to animais treated on the 6th day following infection (28.5% cure rate).


Metal matrix composites consisting of 6061 and 2014 aluminium alloys, reinforced with 10%, 15% and 20% alumina particulates and a 6061 alloy reinforced with 20% SiC particulates, have been characterised in terms of their behaviour under various tribological conditions. In abrasive environments, the wear behaviour of each composite is dominated by their ability to resist indentation by hard particles. Abrasion against fine grit particles leads to a reduced load per abrasive particle and a correspondingly significant reduction in wear loss. Reciprocating sliding wear tests, conducted in an aqueous environment and against hardened steel counterfaces, displayed composite wear rates that were up to three orders of magnitude below those of their monolithic alloys. This is attributed to the increased resistance to surface shear provided by the reinforcing particulates themselves and their constraining effects on the matrix. The particulates become load bearing and protect the matrix by reducing the metal to counterface adhesive wear. However, the counterface wear increases due to the interaction with the hard reinforcements. Transmission electron microscopy of the worn composites reveal the formation of a transfer layer and subsurface dislocation structures which are similar to those found in metals subjected to low amplitude fatigue. In contrast to the results for abrasive and sliding wear, the composites show increasingly inferior cavitation and solid particle erosion resistances with increasing volume fractions of particulates. This depreciating effect was especially evident for particle erosion and can be related to the inability of metal matrix composites to accommodate the increments of strain which accompany erosive processes. The mechanisms responsible for the various performances have been studied by scanning electron microscopy, optical microscopy and transmission electron microscopy. An attempt is made to reconcile the steady state wear rates of the reinforced and unreinforced alloys with their observed wear modes, microstructures and bulk mechanical behaviour.


Osteomalacia is an abnormality of bone characterized by an accumulation of increasing matrix and epiphyseal cartilage, which fails to calcify or does so extremely slowly. Diagnosis is made histologically by widened osteoid seams and is radiologically dependent upon the demonstration of looser zones or pseudofractures, [1 , 2]. Osteomalacia may result from various etiobogic factors that may be divided into three major groups as by Mankin [3]: 1 .-Deficiency states, including primary vitamin D deficiency (lack of intake or ultraviolet exposure), calcium or phosphorus deficiency, and chelators (oxalate, phosphate). 2 .-Absorbtive defects, including gastric, pancreatic, intestinal, and hepatobiliary disorders, including postsurgical defects. 3.-Renal disease, including tubular defects or renal tubular acidosis from congenital abnormalities. Acquired disease can cause renal tubular acidosis or renal osteodystrophy. Miscellaneous causes of osteomalacia include fibrous dysplasia, neurofibromatosis, and osteopetrosis [4]; medication including Dilantin and phenolphthalein [5]; neoplasms, both benign and malignant, of either bone or soft tissues; and unclassified causes, including hypophosphatasia, axial osteomalacia [4], fibrogenesis imperfecta osseum [5], and fluoride ingestion [4]. The cause of the osteomalacia is usually obvious when the radiographs are positive; occasionally, the underlying disorder is occult and familiarity with the various etiologies and associated diseases may enable the radiologist to suggest the correct diagnosis. Our recent experience with two cases of osteomalacia in which the discovery of the underlying abnormality led to profound changes in therapy and prognosis form the basis for this report.


The proteolytic formation of thrombin is catalyzed by the prothrombinase complex of blood coagulation. The kinetics of prethrombin 2 cleavage was studied to delineate macromolecular substrate structures necessary for recognition at the exosite(s) of prothrombinase. The product, α-thrombin, was a linear competitive inhibitor of prethrombin 2 activation without significantly inhibiting peptidyl substrate cleavage by prothrombinase. Prethrombin 2 and α-thrombin compete for binding to the exosite without restricting access to the active site of factor Xa within prothrombinase. Inhibition by α-thrombin was not altered by saturating concentrations of low molecular weight heparin. Furthermore, proteolytic removal of the fibrinogen recognition site in α-thrombin only had a modest effect on its inhibitory properties. Both α-thrombin and prethrombin 2 were cleaved with chymotrypsin at Trp148 and separated into component domains. The C-terminal-derived ζ2 fragment retained the ability to selectively inhibit macromolecular substrate cleavage by prothrombinase, while the ζ1 fragment was without effect. As the ζ2 fragment lacks the fibrinogen recognition site, the P1-P3 residues or the intact cleavage site, specific recognition of the macromolecular substrate by the exosite in prothrombinase is achieved through substrate regions, distinct from the fibrinogen recognition or heparin-binding sites, and spatially removed from structures surrounding the scissile bond.


The identification and classification of the items managed by an organization is the key to control the all processes assigned to it. Hence, the development of suitable item identification and classification systems is of particular importance. Present work starts by analyzing different item registration methodologies currently used in the company OGMA and understanding its application in several company areas such as Engineering, Planning, Purchasing, Logistics or Production. The aim of this thesis is to purpose an integrative standardized model for the different forms of logging items in the system through the partition of the information necessary to identify them into a predefined number of segments, instead of being concentrated in a single undifferentiated field. It is proposed a model capable of identifying the universe of items managed by the company and represented by a matrix in which the rows represent the different item types and the columns each information segment. All the nine defined segments are present in each item type identifying structure, containing information or not, depending on the specified segments to identify each particular item type. The proposed model ensures its applicability to the company context through the Oracle Flexfield concept. In conclusion, segmentation of information when applied to an intelligent item identification system appears itself as a tool capable of reducing the amount of resources needed to ensure the maintenance and strength of the system over time, providing huge advantages especially in terms of information management and the establishment of standardized identifying criteria.


The invention relates to a method for evaluating medical image data of an examination object, an evaluation unit, a medical imaging apparatus and a computer program product.

A thermal roughening transition in a polycrystalline nickel surface dissolved anodically by a rectangular pulse current is found. The drastic change in normalized dissolution mass at the transition temperature is shown to be consistent with that in surface roughness such as a smooth or rough surface. The normalized dissolution mass below the transition temperature exponentially decreases with the frequency of the rectangular pulse current and asymptotically approaches a fixed value much less than 1.0. The normalized dissolution mass above the transition temperature is almost equal to 1.0 irrespective of the frequency. The frequency dependence of the normalized dissolution mass is described by an electric circuit model equivalent to an electric double layer.


Galaxy cluster Abell 370 contains an astounding assortment of several hundred galaxies tied together by the mutual pull of gravity.


This study aimed to evaluate educational services offered for Syrian gifted refugee students in Jordanian schools from the point of view of schools' principals or educational supervisors. The researchers extracted validity and reliability indicators from the Arabic translated form of the National Association for Gifted Children (NAGC) standards. 72 schools were evaluated in terms of the use, importance, and availability of the four gifted education standards: identification, curriculum, programs, and professional development. The findings showed that there are differences in the numbers of gifted Jordanian students compared with Syrian students enrolled in gifted programs in Jordanian schools. Moreover, there is a gap between types of gifted educational programs and services provided in the schools inside and outside the refugee camps. The findings also showed that the overall gifted education services provided for Syrian gifted refugee students were low with an average of 2.34 for the use, 2.15 for the importance, and 2.44 for the availability of these practices. Finally, suggestions and recommendations are provided to develop the gifted educational services in these schools.


SINCE Toynbee's (1860) observation, we have known that the tympanic membrane moves during deglutition. From Politzer we learned tubal insufflation. He was the first to describe, in 1862, serous otitis media as a consequence of tubal catarrh. Zollner in 1942 published a very important book about the pathology of the Eustachian tube and recently, in 1977, an International Symposium on the Physiology and Pathophysiology of the Eustachian tube and middle-ear was held in Freiburg. As clinicians we know that the weakest point of the whole air-filled middle ear system is the drum membrane. Like a window it shows all the changes within the tympanic cavity: pressure differences, by protrusion or retraction; loss of details, in cases of inflammation, scars or perforation; as signs of defective healing. The most difficult part to diagnose and treat, the key to otitis media, is the auditory tube. Tympanometry enables us to demonstrate the function of the tube. My effort now shall be to correlate morphological findings with dysfunction. Our material is all human, from our temporal bone collection originally started by O. Mayer. One has to keep in mind the one great limitation of morphology: the histological picture is like a snapshot; only a lot of pathohistological data allow conclusions.


The course of the electrochemical hydrogen reaction on smooth tungsten-carbide electrodes in hydrogen saturated 2.25 Μ H2S04 follows a electrochemical sorption-desorption mechanism in the potential range of 0 . 4 to +0.1 V (RHE). At potentials greater than +0.1 V (RHE) the hydrogen oxidation is controlled by a preliminary chemical sorption step. Concluding from the similar behaviour of tungsten-carbide and tungsten electrodes after cathodic pretreatment, different tungsten oxides should be involved in the course of the hydrogen reaction on tungsten-carbide electrodes.


The changes of land use in Ternate Island due to the presence of Ternate City in
the Island, has led to increase the area that is built up which then have an impact
on the reduction of water catchment areas. if it continues then it will contribute to
the improvement of the direct flow resulting in increasingly large peak flows in
the river. Therefore we need the data, information and strategies in dealing with
these problems. The objective of this study is to be : (1) estimated peak discharge
at the entire watershed on the island of Ternate. (2) determine the approximate
amount of rainfall can cause flooding at each outlet stream, and (3) review of
flood mitigation strategies based on the design of land use change scenarios.
One of the methods that can be used to measure the magnitude of the peak flows
in a small watersheds it's The Rational Method. This method itself works by three
main parameters: (1) Runoff Coefficient, (2) Watershed Area, and (3) Intensity of
Rainfall. Calculation results obtained from these methods, then be validated by
using the Manning equation. This equation is done at each watershed outlet where
the parameters are measured and observed left-right width and height of the river
embankment, slope and surface roughness values of the river.
s
Based on the results of the processing of the Rational Method and Manning
Equation, obtained each return period either 2, 5, 10, 20 and 25 years, watersheds
that have the smallest peak discharge is Sulamadaha II and which has the greatest
peak discharge is Takoma. The magnitude of the difference peak discharge using
the rational method, is determined by the physical characteristics of a vast
watersheds and land uses of each watersheds, whereas the characteristics of rain
precipitation has no effect because the calculation process is done, the value is
considered equal for all watersheds. However, in determining the intensity of rain
each watershed differ due to differences in the concentration time (tc) of each
watershed . Then within a period of 25 years, all watersheds in the island of

summer 2013 (1889). The Glenbeigh evictions occurred in January 1887 and are one of the focuses of Curtis's narrative of the 1880s. They involved the burning of cabins to prevent reentry, something that required the pouring of paraffin on the rain-sodden thatched roofs. A dozen english reporters arrived to cover the story. The pathetic drawings of distraught tenants by Amédée Forestier of the Illustrated London News and other images of police brutality created a sensation that Fleet street editors were quick to exploit, as the continuing evictions in the area deteriorated into violence. As the Land Wars wore on, the authorities turned to novel and yet rather antique methods. Curtis devotes a chapter to the use of the battering ram and its depiction in cartoons. At one and the same time it was seen to betoken a particular brutality and yet also to gesture toward the ludicrous, a fact that the satirical Punch was not slow to exploit. Images of evictions confirmed Irish resentments and, according to Curtis, led Britons to conclude that Ireland was a foreign country (and thus presumably softened opinion for self-government concession to Ireland). Curtis's book is thoroughly researched and provides micro-narratives of dozens of notable evictions over a sixty-five-year period. They often make fascinating reading at the level of human drama. undoubtedly, there was a large degree of skilful propaganda on the nationalist side, and British and Irish newspapers had their own agendas. Yet, there was also a large degree of human suffering involved in the eviction process and Curtis does well to remind us of it. Perhaps if we had a greater sense of the human suffering behind the ineluctable economic forces of our day it would do us all some good. James H. Murphy DePaul University


The history of water management in The Netherlands shows how the original natural landscape was transformed into a man‐made landscape and has led to a never‐ending struggle with the water. Water comes from all directions into the lowlands: over land via rivers (floods), from the sea side (surges), from above (excessive rainfall) and from the subsoil (seepage). Human intervention is continuously needed to be able to survive with effective solutions. History has shown that since men started intervening in nature, in particular in the alluvial water‐saturated soft soils where Dutch society has settled and developed, the need for these measures will never stop. Any one measure leads to counter and correcting measures later on. This is clearly visible today and it will definitively continue in the future. It sets the mind of Dutch society in its continuous struggle for life and can be a lesson learned for others, living and developing in areas with similar water‐related characteristics.

Amos prophesied for only a matter of two years, and this accords well with what we can learn of Amos' career from his book. If it is true, and the author probably had knowledge of the facts, it finally disposes of a problem that has long concerned Old Testament scholars: whether or not the ministry of Amos was for a short period of time and just how short it was, most recently discussed by Gordis in the Harvard Theological Review 33 (1940). 239 ff. Through careful attention to Hebrew syntax we learn for the first time that Amos prophesied for a period of two years only, and it seems strange that a matter, so simple and yet so important, should have been so long overlooked.

Laser noise has been well studied both theoretically and experimentally. Most of the previous experimental work examined the standard deviation of the noise, with the implicit assumption of a Gaussian noise distribution. We employ a new approach to measure the semiconductor laser noise distribution down to a bit-error ratio (BER) of 10-11. This method takes advantage of the high sampling rate of modern BER testers. We found that the noise distribution for a 1310-nm Fabry-Perot laser and a 1550-nm distributed-feedback laser are well fitted by Gaussian distributions

The article reviews J.J. Pudełko's book-length study titled Profetyzm w Księdze Syracha [Prophetism in the Book of Sirach]. Following an initial presentation of the book, the author focuses on its methodological aspect and offers an assessment of its merit before discussing the main thesis of Pudełko in the context of other scholarly opinions on the issue. Based on her meticulous analysis of prophetism in the works of the Jerusalem sage, Pudełko concludes that Sirach saw himself as an heir to the Old Testament prophets, as his role of a sage corresponded to the tasks fulfilled earlier by prophets. Although this argument is questioned by most contemporary analysts of the Book of Sirach, still Pudełko's book constitutes an important intervention in the debate on Sirach's prophetic self-awareness.


This article explains the need for the automotive industry to work together in order to move forward in the area of safety technologies. The focus here is vision assist, and specific examples mentioned here are as follows: vision protection (mirrors that dim automatically to adjust glare), side blind zone management (special curved side mirrors and blind zone alerts), and eliminating rear blind zone (rear cameras). The question still remains as to how the industry can increase its adoption rates of these safety technologies.


The selection of arbitrators is a fundamental phase in the arbitral proceeding. At times, circumstances involving potential arbitrators may raise doubts to the party regarding their impartiality and independence. In this sense, arbitral institutions take on a very relevant role in institutional arbitrations, since they are the ones to decide potential objections to arbitrators. The present article analyses specifically the alteration brought by Article 145, I of the Civil Procedure Code with respect to the grounds of impartiality for judges ("impediment" and "suspicion") – which are also applicable to arbitrators according to the Brazilian Arbitration Act – and the way in which CBMA – Brazilian Center of Mediation and Arbitration has been interpreting such alteration, also based on IBA Guidelines on Conflicts of Interest in International Arbitration.


A combined experimental and theoretical study of the reactivity of small boron cluster cations with HF is reported on in this article. Cross sections for the reaction of mass-selected boron (Bn+, n=2–14) and boron monohydride (BnH+, n=4, 7, and 10) cluster ions with HF are reported for collision energies from 0.1 to 10 eV. The reaction proceeds via a chemically bound intermediate complex, and the major product channels involve elimination of BF or H from the BnHF+ intermediate. Both reactivity and product branching depend strongly on cluster size. Reactivity at low energies generally decreases with increasing size, with the appearance of significant bottlenecks to reaction. The effect of adding a hydrogen atom to the reactant clusters was examined for several cluster sizes. In contrast to the boron oxides, hydrogenation of elemental boron cluster ions has little effect on reactivity with HF, suggesting that H does not compete effectively for HF binding sites. The results provide a sensitive test for the a...

ABSTRACT In the history of twentieth-century literature, futurism was one of the most technology-focused experimental movements. By modern technology, one can understand, for example, the object of desire, prosthesis, model, tool, and poesis. This article, however, discusses the curious fascination with transportation disasters and malfunctioning machines (particularly cars, trams, and planes) in the poetry of Polish futurists. The author argues that these images reflect repressed technological anxiety present in discursive practices of the interwar media in Poland. A close analysis of Yeży Yankowski's "Burning of the Aviator," Bruno Jasieński's "Corpses with Caviar," and Tytus Czyżewski's "The Flame and the Well" presents diverse strategies of self-exploration for the anxious modern subject and varied approaches to the question of representation. In this poetry, defective machines are not just agents of doom but also, peculiarly, essential elements of the defence mechanism in the psychic apparatus. Drawing from psychoanalysis, the author understands writing as the "talking cure" and frames reading as spectatorship. Consequently, the poems become exercises in losing and gaining agency, thereby enabling the subject to overcome fear of technology.


This paper presents a scheme of frequency and sampling clock synchronization for CMMB system.Theoretical analysis and simulation results show that this scheme has low complexity and good performance to complete the frequency offset and sampling clock frequency offset estimation.


Abstract Background We have previously found that the energy level in sows affects the activation of primordial follicles. Glucose is the primary metabolic substrate of dietary energy and its effect and mechanism of action with regards to the activation and development of primordial follicle remain unclear. Studies utilizing several different animal cells have shown that energy stress, induced by glucose starvation, activates AMPK and participates in a variety of cellular processes by regulating the Hippo and mTOR signaling pathways. However, whether glucose can affect primordial follicle activation through the above pathways has not been reported. Methods We developed an in vitro culture system for mouse ovaries to investigate the effects of glucose on the primordial follicle activation. Protein expression of AMPK‐Hippo‐YAP and AMPK‐mTOR pathway was investigated under glucose starvation and optimal glucose level treatment. Then, ovaries were treated with AICAR or Compound C in vitro to explore the effect of AMPK activation or inhibition on primordial follicle activation, and the changes of AMPK‐Hippo‐YAP and AMPK‐mTOR signaling pathways. Finally, investigated the signaling pathways affected by glucose potentially affecting the primordial follicle activation in vivo. Results The glucose was an essential nutrient for primordial follicle activation and we identified 25 mM glucose as the optimal level (P < .05) for the primordial follicle activation in vitro. The glycolysis pathway was involved in primordial follicle activation (P < .05) of ovaries cultured in vitro. The glucose affected the activation of primordial follicles in vitro through AMPK/mTOR signaling pathway by AMPK activation or inhibition treatment and follicle ratio count (P < .05). Moreover, glucose affected the primordial follicle activation of ovary in vivo via mTOR signaling pathway. Conclusions This study demonstrates that glucose affects the primordial follicle activation through the AMPK/mTOR rather than the AMPK/Hippo signaling pathway.


Many people in the United States know about the Gulf Stream, the impressive boundary current along the eastern U.S. coast that carries large amounts of heat poleward and, after separation from the coast, across the North Atlantic. Its impact on warming the eastern United States and the North Atlantic region including western Europe is also well known to the general public.

But who in the United States knows about the Agulhas Current? This warm, western boundary current of the southern Indian Ocean flows southward along the continental slope of the African continent and is about as large as the Gulf Stream. It brings heat and moisture to the coastal regions of southeastern Africa. Variations in its transport lead to significant rainfall anomalies over this region. On a larger scale, its influence may even extend as far as the North Atlantic.

"Community systems are created, maintained, or modified by human behavior and interaction," say Berger and Luckman. Society and social institutions are objectively realistic, but in reality they are all subsumed into subjective definitions through a process of interaction. New objectivity emerges through repeated affirmations given by other people who have the same subjective definition of that definition. At the highest geological level, humans created the world in a universal, universal and symbolic sense. In short, in a holistic view of life, Suluk Gus Dur's teachings of Sufism are Islamic teachings that focus on awareness whole self. Awareness and self-centered understanding of Islam as a whole. Awareness of having a noble personality,and personality creates a personality based on self-awareness that emerges from social attitudes and becomes a highly socially conscious social personality.


Fresh water scarcity and pollution turn out to be a most serious issue throughout the world due to the rapid population growth. The application of nanomaterials (NMs) for the removal of pollutants from water has attracted significant attention. The nanofiltration membrane was fabricated through the evaporative casting (EC) method using multiwalled carbon nanotubes (MWCNT) and chitosan (CHIT) as the surfactant to enable water purification. The developed EC membrane properties were characterized in mechanical, surface charging (zeta potential), surface morphology, and hydrophobicity properties. Results demonstrated that incorporation of MWCNT and the biopolymers (chitosan) resulted in suitable developments in mechanical properties of the membrane. For example, the membrane has shown values for tensile strength (28 ± 1 MPa), elongation (10.2 ± 1.2%), Young's modulus (1.2 ± 0.1 GPa), and toughness of (1.9 ± 0.2 J/g). When more significant changes were investigated on the surface morphology of the EC membrane, it was observed that the pores on the surface morphology of the EC membrane decreased as the evaporative casting method was used. Moreover, the permeability of the membrane towards water, inorganic salts, and pH effect on salt rejections was studied using the NF/RO system. These established nanocomposite membranes signify the promising candidates for fresh water desalination and elimination of organic impurities.


Leadership is a subject that has been studied since ancient times through various approaches. Leadership in Islam is a process that guides and motivates its followers or members of the organization towards the achievement of a clear organization purpose and vision blessed by Allah SWT. Existing Islamic leadership theories have not explicitly focused on issues in quality management. This study attempts to contribute towards the development of theory on Islamic leadership for quality management, with the main focus to develop an instrument to measure the leadership for quality management from Islamic perspective. Instrument building measures include the identification of dimensions of the instrument through literature review, construction
of items, checking for the validity and reliability and ultimately the use of factor analysis methods to cluster the items into the related dimensions. A census was carried out on all 45 government departments in Aceh, a Province in Indonesia. The data were collected and analyzed using the Statistical Package for Social Science (SPSS). Leader values and leader traits are the two dimensions identified in the measurement of Islamic leadership for quality management. Based on the two dimensions, a total of seven elements were identified to measure the dimensions of leadership values which are; commitment of leadership, customer focus, quality policy, quality planning, management review, Islamic corporate culture and lastly, responsibility, authority and communication. While the seven elements contained in the leader traits that are al-fahm, al-mua'alli, al-munazzhim, at-tsiqah, at-takayyuf, as-siddiq, and al-fathonah. The study resulted in the development of Islamic leadership for quality management instrument which consists of 71 items. The reliability of the instrument meet established standards. This instrument also has the ability to predict or measure the concept of Islamic leadership for quality management in an organization, especially Islamic-based organization.

The exponential growth of IoT (Internet of Things) imposes increased needs for understanding and exploitation of EM phenomena. Consequently, there are growing demands for more flexible, accurate, and efficient 3D EM simulation, easy accessible to many engineers, many of them lacking deep knowledge of applied electromagnetics. To meet such needs it is necessary to adjust existing tools to create friendly 3D simulation environment, not only for development and testing of IoT, but even for inclusion of these tools into functioning of IoT. In this paper we propose the concept/structure of such environment. For the base of such environment we propose WIPL-D commercial general-purpose 3D EM solver WIPL-D Pro and its CAD variant-WIPL-D Pro CAD. In addition we added libraries of EM models of a) electrical components (e.g. antennas), b) environmental elements (e.g. moving platforms, indoor/outdoor objects, human phantoms), and c) templates that combines electrical components and environmental elements into IoT scenarios. Special tools/procedures are included/developed to enable easy creation of new libraries' components and their composition into complex scenarios, as well as for effective processing of EM field data obtained by simulation. The effectiveness of such 3D EM simulation environment will be shown on a number of practical examples.

Many carbon-based nanomaterials exhibit nonlinear optical response under intense laser radiation what makes them promising candidates for laser protection devices. They strongly attenuate intense laser light, while exhibiting high transmittance at low irradiation levels. In literature this behavior is mainly related to nonlinear absorption and nonlinear scattering. C60 and MWCNT are carbon-based materials with high optical limiting efficiency. It is generally believed that the main optical limiting mechanism of MWCNT suspensions is NL scattering whereas C60 solutions show mainly nonlinear absorption. In the case of MWCNT we observed a strong scattering signal arising near the nonlinear threshold when tested with nanosecond laser pulses at 532 nm, which is in agreement with results in literature. C60 exhibits only weak NL scattering and their OL behavior is due to NL absorption in the intermediate NL regime. In addition, we observed a diffraction pattern for high input energies, induced by local refractive index changes.


A novel two stage load-balanced multipath self-routing switch structure is introduced in this paper. Both stages use a multipath self-routing fabric. With simple algorithms and small buffers, the first stage fabric transforms the incoming traffic into uniform and the second stage fabric forwards the data in a self-routing manner to their final destinations. Compared with other similar structures, this structure outstands with no queuing delay and zero jitter, its component complexity and propagation delay are significantly reduced. Mathematical analysis and simulations show this structure can achieve 100% throughput under admissible traffic pattern, which is a common presumption for incoming traffic. For statistically admissible traffic, by stacking up a few copies of this structure, it is suitable to support QoS application for building super large scale switching fabric in next generation network(NGN).


Asphalt technologists have long recognized the need to carefully control mixture production to ensure satisfactory in-service performance. Asphalt-aggregate mixtures that are sensitive to variables controlled during production including asphalt content (AC) and gradation, particularly percent passing the 0.075-mm sieve (p0.075), have the potential to exhibit poor performance. Typical production standard deviations for AC and p0.075 are 0.3% and 0.9%, respectively. This mixture sensitivity analysis shows that variations of this magnitude can result in significant changes in laboratory volumetrics and subsequently field rutting performance. The four basic mixtures designed for the WesTrack project were examined, including the original coarse, fine, and fine plus mixtures, and the coarse replacement mixture. Coarse-graded mixtures were more sensitive to AC, and fine-graded mixtures were more sensitive to p0.075. The replacement mixture was relatively insensitive to p0.075, and one of the fine mixtures was extremely sensitive to reductions in p0.075. Results also suggest that mixture sensitivity may affect optimum AC selection by up to 1.0% and thus impact field rutting performance. A comparison of sensitivity ratios based on a performance indicator (air voids) and measured performance (rut depths) highlighted elevated sensitivities of the coarse-graded mixtures to decreases in AC as compared to fine-graded mixtures and sensitivities of all mixtures evaluated to increases in AC. When measured sensitivities were compared to those predicted from field calibrated models, the potential for extreme sensitivity was demonstrated by errors in predicted changes in air voids that ranged from 1% to 105% due to small changes in AC or p0.075. These findings reinforce the crucial need for a mixture performance test to augment the Superpave volumetric mix design system. The conclusions drawn warrant a recommendation that mixture sensitivity analyses are needed in this mix design process. A mixture sensitivity analysis is presented that is useful for identifying sensitive mixtures and serves as an excellent field quality management tool.

Introduction Breast cancer is the most common malignancy among women in most parts of the world. The lack of effective conventional treatments for breast cancer has attracted substantial attention in the search for new treatment modalities. A variety of immunotherapeutic regimens have been evaluated in recent years (Moingeon, 2001). While the specific etiology of breast cancer remains unknown, DNA vaccines directed at eliciting an immune response toward tumors appear to offer promise for both the prophylactic and therapeutic treatment of cancer. The recent identification and cloning of several breast cancer-associated antigens make it possible to develop antigen-specific cancer vaccines. Among them, MUC-1 is an attractive candidate for use in vaccine development because it displays lower sequence variability in the human breast and plays critical roles in mammary tumorgenesis (Spicer et al., 1995). The ultimate goal of cancer immunotherapy is to induce effective tumorspecific cellular immunity that can inhibit or block the growth and metastasis of tumor cells. Therefore the development of a protocol to induce Th1 response may be required to develop more efficient immunotherapy. Interleukin (IL) 18, a well identified Th 1-biasing cytokine, mediates many important biological functions including inducing of interferon (IFN)-γ production, stimulation of T cell proliferation and regulation of FasL-dependent apoptosis (Okamura et al., 1995; Hashimoto et al., 1999). In this study, the strategy of using IL18 and MUC-1 genes was used as potential candidates for the DNA vaccine development against human breast cancer. Materials and Methods


This paper discusses the issue and dispute in Bai Bithaman Ajil (BBA) which ended in court cases. It attempts to define the issues and dispute that rise in the practice of BBA and the practical case of BBA in the context of Malaysia and Shariah perspective in regards to BBA practices. Critical analysis from the existence literature is employed to answer the objective of the paper. It shows that the dispute happened due the customer has less understanding regarding the contract in BBA. The court cases that occurred between the bank and the customer were always won by the bank because the bank has more legality and the judge won the bank in order to maintain the good image of Islamic bank in the eye of public.


Abstract Potassium-phosphorus binaries are able to intercalate into graphite as potassium-oxygen or potassium-sulphur binaries, so that phosphorus behave as a classical electronegative element. But, it is able, on the other hand, to behave as a metal such as mercury, so that potassium-phosphorus and potassium-mercury binaries intercalate into graphite by very close synthesis routes. Phosphorus appears thus as a linking element between strongly and fairly electronegative species.


Teachers perceive classroom management to be one of the most enduring and widespread problems in education. This paper presents findings of a study that continued efforts to refine the Attitudes and Beliefs on Classroom Control (ABCC) Inventory. Formerly called the Inventory of Classroom Management Style, the ABCC is an instrument designed to measure teachers' perceptions of their classroom-management beliefs and practices. The study sought to investigate differences between the classroom-management style of male and female educators. A second objective was to substantiate the construct validity of the ABCC Inventory. The ABCC and selected subscales of the 16 Personality Factor Questionnaire (16 PF) were administered to 282 teachers in the southwestern United States. Twenty-two percent of the teachers taught at the elementary level and 61 percent taught at the secondary level. Females accounted for about two-thirds of the subject pool. Male teachers scored significantly higher in the interventionist style on two of the three ABCC subscales and significantly higher on "dominance" on the 16 PF. Several correlations with ABCC subscales and selected 16 PF subscales proved significant, were both positive and negative in direction, and were consistent with the construct.

that build open-faced paper nests in which offspring are reared. The lack of distinct morphological castes and great plasticity in social behaviour among females, combined with the ease of observing individually paintmarked adults, has made this a model genus for behavioural studies (Reeve 1991; Turillazzi & WestEberhard 1996). All species are eusocial, but at a relatively rudimentary level: colonies are relatively small (Reeve 1991), workers are not consistently different from queens (Haggard & Gamboa 1980), social relations are often characterized by strife (West-Eberhard 1969; Strassmann 1981a; Noonan 1981), and the queen in some species must act as the pacemaker, physically manipulating workers into working (Reeve & Gamboa 1983). Polistes has served as a model system for a wide variety of topics including dominance hierarchies (WestEberhard 1969), advantages of group living (Strassmann et al. 1988; Strassmann & Queller 1989; Strassmann 1991), kin selection (Noonan 1981; Strassmann 1981b; Queller & Strassmann 1988), kin recognition (Gamboa et al. 1987), usurpation (Klahn 1988), and social control by queens (Reeve & Gamboa 1983). To date, it has been difficult to combine detailed studies of behavioural interactions with studies of genetic relatedness because of the difficulty in obtaining precise estimates of relatedness for individual pairs of interactants with the available genetic markers (e.g. Strassmann et al. 1989). Clearly, a more polymorphic set of markers is needed. Microsatellite loci are highly polymorphic, codominant, and can be genotyped from many sources of DNA including alcohol-preserved tissues and sperm in a female's spermatheca (Evans 1993; Queller et al. 1993; Peters et al. 1995). Here we present 18 new microsatellite loci derived from Polistes bellicosus and eight new loci from Polistes annularis. All of these loci contain trinucleotide repeat regions which are much easier to score unambiguously than are dinucleotide repeats. To obtain these loci we constructed very large partial genomic libraries in plasmids with inserts (not enriched for microsatellites) averaging 500 bp (Hughes & Queller 1993; see Strassmann et al. 1996, for the rationale of our approach and specific protocols). We separately probed replicate membranes with synthesized oligonucleotides containing 10 or 12 repeats of either AAT, AAC, AAG, CAT or TAG, five of the 10 possible trinucleotide repeats. We picked up hundreds of potential positives. Reprobing a Southern blot of the inserts indicated that most of these sequences contained repeats. We sequenced part or all of about 80 clones of P. bellicosus. Of these, 59 contained at least one repeat region. We designed polymerase chain reaction (PCR) primers for clones containing uninterrupted repeats, five or more repeats long for which we could read the flanking regions (Table 1). We did not design PCR primers around all repeats for reasons including the nature of the flanks, absence of sufficient flanking sequence, or because they were dinucleotide repeats, not the trinucleotides we were after. We evaluated these primers for heterozygosity on 3–24 unrelated individuals. Genomic DNA was prepared as described in Hughes & Queller (1993) or using protocol Strassmann.1 in Strassmann et al. (1996). PCR was carried out under oil in a 10 μL volume made up of 2 μL diluted genomic DNA (about a nanogram), 2 μL of primer mix (2.5 μM), 0.1 μL 10 mM dNTP mix, 1 μL 10× buffer (provided with Taq), 4.08 μL dH2O, 0.62 μl 25 mM MgCl2, 0.05 μL Taq polymerase (5 units/μL, Promega), 0.15 μL 35S dATP (12.5 μCi/μL). After an initial denaturing for 5 min at 95 °C, we carried out 30–35 cycles of 60-s denaturing at 92 °C, 60-s annealing (at a temperature optimized for the primers used: see Table 1) and 45-s extension at 72 °C. After that, 5 extra minutes at 72 °C allowed for the completion of the extension. PCR products were run on 6% denaturing acrylamide gels (Strassmann et al. 1996). All of the 18 microsatellite loci proved to be polymorphic in P. bellicosus though heterozygosity varied from 0.05 to 1 (Table 1). Seven of the eight loci from P. annularis proved to be polymorphic, with heterozygosities ranging from 0.17 to 1 (Table 1). We have published other microsatellites for Polistes annularis and for another social wasp, Parachartergus PRIMER NOTE

The article studies the theatrical nature of the creative method of the artist William Hogarth in creating paintings and graphic series "A Rake's Progress" and the composer Igor Stravinsky in creating the opera "The Rake's Progress" based on the engravings of the artist. The formation of theatrical thinking is shown, its origins and interaction with diverse phenomena of English culture in the work of Hogarth and Stravinsky are determined. The author pays particular attention to the issue of the identical creative way that brings out the unity of theatrical thinking, as well as the genre specifics of Hogarth and Stravinsky, scenic and musical dramatic art for the creation of a scenic and pictorial form. The article analyzes the stylistic features that reflect the main trends of English culture of the 18th century and European culture of the first half of the 20th century. It examines in detail the expressive means subordination of the musical pattern to the picturesque dramaturgy of the artist.

While leading private-sector agricultural biotechnology firms with strong IP positions and commercial freedom to operate (FTO) see insufficient incentives in the small, fractured markets of horticultural products, researchers with public-sector support for horticultural projects but weak IP positions may find that the best way of gaining FTO and moving forward is to band together and provide mutual access to one another's technologies. The Public Intellectual Property Resource for Agriculture (PIPRA), headquartered at UC Davis, is a new coalition of U.S. universities and foundations committed to this strategy.


Excess air coefficient (λ) is the most important parameter characterizing the combustion efficiency. Conventional measurement of λ is practiced by way of the flue analyze device with high market priced. Estimating of the λ from flame images is crucial in perspective of the combustion control because of decreasing structural dead time of the combustion process. Beside, estimation systems can be used continuously in a closed loop control system, unlike conventional analyzers. This paper represents a basic λ prediction system with a neural network for small scale nut coal burner equipped with a CCD camera. The proposed estimation system has two inputs. First input is stack gas temperature simply measuring from the flue. To choose the second input, eleven different matrix parameters have been evaluated together with flue gas temperature values and performed by matrix-based multiple linear regression analysis. As a result of these analyses, it has been seen that the trace of image matrix obtained from the flame image provides higher accuracy than the other matrix parameters. This instantaneous trace value of image source matrix is then filtered from high frequency dynamics by means of a low pass filter. Experimental data of the inputs and λ are synchronously matched by a neural network. Trained algorithm has reached R=0.984 in terms of accuracy. It is seen from the result that proposed estimating system using flame image with assistance of the stack gas temperature can be preferred in combustion control systems.


Because of the differences between language and thinking mode, different nations have their own cultural differences and these lead to the barriers during cultural communication. Therefore, understanding to different cultures is the presupposition of cultural communication, while absorbing the cream of different cultures is the aim.


The Bondi-Metzner-Sachs group is topologized as a nuclear Lie group, and it is shown th at irreducible representations arise from either (i) transitive SL{2,C) actions on supermomentum space, or (ii) cylinder measures in supermomentum space with respect to which the SL(2,C) action is strictly ergodic. The irreducibles arising from transitive actions are shown to be induced, and most of the theorems from a previous analysis (in which the group was given a Hilbert topology) are generalized so as to apply here. All non-discrete closed subgroups of 2, C) are found, and this analysis is used to construct all induced representations whose little groups are not both discrete and infinite. In the previous analysis, there were exactly two connected little groups, SU{2) and r (T double covers $0(2)). In the present analysis, exactly one additional connected little group A (which double covers E{2)) arises for faithful representations (that is, those for which the mass squared is defined); the associated mass squared value is zero. Exactly one further connected little group arises;


Copper oxide (CuO) nanoparticles (NPs) were decorated on reduced graphene oxide (rGO) through the effective synthetic route method. Powder X-ray diffraction, Fourier transform infrared, ultraviolet-visible absorption, and scanning electron microscopy techniques were used to analyze the chemical structure, functional groups, absorbance, and morphology. Under visible light illumination, the CuO/rGO nanocomposites have higher catalytic activity compared to the bare CuO NPs which were suitable for degradation of methylene blue (MB) and Congo red (CR) dyes. According to the findings, the CuO/rGO nanocomposites possess excellent photocatalytic efficiency. Thus, the synthesized CuO/rGO nanocomposite is a promising photocatalyst for the deterioration of organic pollutants in water and wastewater treatment.


This paper reports: (i) the relationship between certain psychological factors (i.e. field dependence/field independence, convergence/divergence and working memory capacity); and (ii) the effect of these factors on the performance of the grid-type of questions and of word association tests in biological concepts.


This paper conducted a bibliometric analysis based on 4687 papers on supplier management from 1997 to 2017. Through a comparative analysis of the four stages using Bibexcel and Ucinet6 software, this paper explores the evolution of supplier management from the theme and cluster perspectives. The results show that supplier management research has made breakthroughs in both breadth and depth. Representative research themes, such as "sustainable supply chain", "corporate social responsibility", "knowledge management", etc., have gradually penetrated into the field of supplier management. Research related to "supplier selection" and "supplier relations" have always been of the highest strategic importance, and themes in "supplier relations" cluster such as "trust" and "commitment" have gradually attracted more and more researchers' attention. The "inventory" cluster has also been a research focus, and the structural stability and maturity of the cluster have gradually improved. The "innovation" cluster is a relatively "open" cluster, and its impact on the entire research filed of supplier management has been gradually increasing. More importantly, the "sustainability" cluster is an evolving cluster, research themes related to "sustainability", such as "green supply chain", "sustainable supply chain" and "green supplier selection", will play an increasingly important role in the field of supplier management.


Abstract : Today, in addition to standard data like numerics and alphanumerics, it is possible to capture, sort, manage, retrieve and present different media information, e.g. sound, image, graphics, text and signals, by using the current, modern computer technology. The Multimedia Database Management System (MDBMS) project, which started at the Computer Science Department of the Naval Postgraduate School in 1988, studies not only the storing, managing and retrieving different media information, but also the management of the interrelationships among the data. This thesis concentrates on the Sound Management Integration of the MDBMS prototype, Which includes the storage and management of the sound records in an IBM compatible personal computer, and the connection and integration of it to the database system in the SUN environment through a local area network, after presenting the general overview of the MDBMS, the system environment, the user interface and the catalog designs.

Three related topics are discussed to show the "simplicity, harmony and beauty" of the theory of special relativity (SR): (1) How can de'Broglie discover his famous relation between the particle's momentum and a wave length -- a paradox stemming from the time dilatation effect of SR. (2) The relativistic Doppler effect, especially the distinction between the transverse Doppler effect and the time dilatation effect. (3) Three particular examples are examined to derive the general mass-energy relation in SR by induction method.

Water resource is getting insecure and turns to conflicting issues if it remains uncontrollable. One of the critical problems that hinder the sustainability of water resource in Malaysia is the water crisis management. In this regard, Malaysia have adopt Integrated Water Resource Management (IWRM) as a holistic approach in order to resolve water crisis management as well as overcome some water issues such as water excesses, water shortage, water pollution, threat from climate change and issues in current state of governance. In view of that, many policies, plans and programmes are being conduct to ensure the IWRM approach can be effectively implement.


For more than a quarter of a century now Professor Louis I. Bredvold's Intellectual Milieu of John Dryden has remained the virtually unquestioned authority on the subject. Only recently have a few dissenting voices been raised against Bredvold's thesis that Dryden's religious development, particularly as that is revealed in Religio Laici, was tainted with skepticism and fideism, and that his conversion, first to Anglicanism, and later to Catholicism, was motivated by irrational considerations. The few voices I refer to are those of Thomas H. Fujimara, whose article "Dryden's Religio Laici: An Anglican Poem," appeared in PMLA in June 1961, and Elias Chiasson, whose essay "Dryden's Apparent Skepticism in Religio Laici" came out in another journal about the same time. Both of these scholars, working independently, demonstrated the orthodoxy of Dryden's Anglicanism with convincing evidence from texts of Anglican writers extending from Hooker to Jeremy Taylor. But can we go along with such a judgment as that which Mr. Fujimara makes in the conclusion of his study—"that Dryden became a Catholic cannot be explained by anything in Religio Laici"? I think not, for reasons which, I trust, will appear in this article.


BACKGROUND There is uncertainty about the correct translation of the term Palliative Care in German speaking countries and the terms "Palliative Care" and "Palliativmedizin" are used and interpreted differently. Therefore one must ask if these terms should be used as synonyms. MATERIALS AND METHODS A focus group discussion on the topic with experts from the field of Palliative Care was conducted. It was based on a literature search by a transdisciplinary, international research group from medicine, nursing sciences and linguistics. The ten participants had all several years experience in the field of Palliative Care and came from different European countries, different professions and were all students of an master's programme in Palliative Care. The focus group discussion was recorded digitally and transcribed verbatim. Methods used were "qualitative description" and "qualitative content analysis". RESULTS All ten participants agreed that the terms "Palliative Care" and "Palliativmedizin" have differences and that they should not be used as synonyms. They define "Palliativmedizin" as a part of Palliative Care. Most participants think that the term "Palliative Care" should be used in German without translation. The differences between the to terms stated during the interview formed the categories multidisciplinarity, attitude, medicalisation, radical patient orientation and holistic view, treatment, pain therapy and historical development. DISCUSSION In the English literature there is a clear distinction between the terms "Palliative Medicine" as medical specialty and "Palliative Care" as multidisciplinary approach including all professions and participants in the field of Palliative Care. The results of our focus group discussion show that the participants agree to this view. A translation of the term "Palliative Care" to German is difficult. The term "Palliativversorgung" is the closest translation including most of the meanings of "Palliative Care". Another solution could be to establish a new term as "Lindernde Umsorgung". CONCLUSIONS According to the participants of the focus group discussion there is a difference between "Palliative Care" and "Palliativmedizin" in German. These terms should not be used synonymously. A public discussion about definitions and areas of "Palliative Care" is needed. The question if the term "Palliative Care" should be translated into German has to be discussed further.


This paper covers 60 years of terrestrial imaging spectroscopy or hyperspectral remote sensing – 30 years each devoted to past and future developments. For this purpose, a brief history of imaging spectroscopy is given, covering civilian airborne sensor and spaceborne mission developments and associated data processing capabilities. Moreover, the paper reviews the existing and planned space systems, examines the current status in hyperspectral remote sensing in terms of data quality and availability, algorithm development, data processing, and applications development. Although many problems have been overcome since the advent of hyperspectral remote sensing, there are still major bottlenecks, as pointed out in this paper, which need to be addressed to further advance this area. Future needs in hyperspectral remote sensing are summarized in terms of space missions and the data products they provide, algorithm development, data processing, and applications development. The paper will conclude by speculating on civilian hyperspectral systems that might be in operation for terrestrial imaging 30 years down the road. In addition, an outlook of the data processing capabilities needed to analyse the increasing volume of data is given for the same time frame.


In this paper, the quality evaluation indexes of cellulose ether (CE) modified dry-mixed mortar are proposed by the comparison of properties of contrast mortar. The technical indexes of CE modified mortar include water retention, anti-sliding value, time difference of final set and the tensile bond strength ratio which give a good guidance for the application effect evaluation of cellulose used in dry-mixed mortar.


OVERVIEW • Urinary protein excretion of <150 mg/day is normal (∼30 mg of this is albumin and about 70–100 mg is Tamm-Horsfall (muco)protein, derived from the proximal renal tubule). Protein excretion can rise transiently with fever, acute illness, urinary tract infection (UTI) and orthostatically. In pregnancy, the upper limit of normal protein excretion is around 300 mg/day. Persistent elevation of albumin excretion (microalbuminuria) and other proteins can indicate renal or systemic illness. • Repeat positive dipstick tests for blood and protein in the urine two or three times to ensure the findings are persistent. • Microalbuminuria is an early sign of renal and cardiovascular dysfunction with adverse prognostic significance. • Non-visible haematuria (NVH) is present in around 4% of the adult population – of whom at least 50% have glomerular disease. • If initial glomerular filtration rate (GFR) is normal, and proteinuria is absent, progressive loss of GFR amongst those people with NVH of renal origin is rare, although long-term (and usually community-based) follow-up is still recommended. • Adults aged 40 years old or more should undergo cystoscopy if they have NVH. • Any patient with NVH who has abnormal renal function, proteinuria, hypertension and a normal cystoscopy should be referred to a nephrologist. • Blood pressure control, reduction of proteinuria and cholesterol reduction are all useful therapeutic manoeuvres in those with renal causes of NVH. • All NVH patients should have long-term follow-up of their renal function and blood pressure (this can, and often should be, community-based). • Renal function is measured using creatinine, and this is now routinely converted into an estimated glomerular filtration rate (eGFR) value quickly and easily. • The most common imaging technique now used for the kidney is the renal ultrasound, which can detect size, shape, symmetry of kidneys and presence of tumour, stone or renal obstruction.


Teaching about classification also plays an important role in nursing education. The International Classification for Nursing Practice is a unified professional language devoted to nurses, other health workers and broader areas. In this paper, the eversion of this classification is presented as a challenge for an efficient educational practice searching for new information solutions in different environments using information and communication technology. Clients on a personal computer, the internet and PDA-hand-held computers are all presented. The combination of those clients in health-care education is analyzed.

A differential microstrip antenna array design for millimeter-wave applications is presented. The antenna is fed by coupled microstrip lines, which facilitates the integration of antennas and differential circuits in RF-front systems. In this work, such an antenna array was designed for an autonomous cruise control application at 77 GHz. The antenna array has a bandwidth of 2 GHz at −10 dB return loss. The radiation patterns of co-polarization are stable over the bandwidth due to the center-fed structure. The 3 dB beam widths are 28 degrees and 78 degrees in the E-plane and the H-plane, respectively, and cross-polarization is very low. The measurement results are in good agreement with the simulation results.


This study compared the performance of delinquent and non-delinquent boys on an operant conditioning task in which social reinforcement was given. It was hypothesized that chronic delinquents would perform poorly in a social learning situation because of an inadequate social environment during the important early periods of life.

Both delinquents and non-delinquents showed evidence of some learning on the task; difference between the groups was greatest in the first part of the conditioning session. Subjects who had high scores on a socialization scale—whether delinquents or non-delinquents—showed more conditioning than Ss with low scores. Results were discussed in terms of the cue property and the reinforcement property of a social stimulus.


This paper describes the design, capabilities, strengths and weaknesses of a tool that collects data from subjects through the Internet. The Internet tool was designed for students studying cardinalities, a difficult data modeling topic frequently taught in the accounting information systems course. The Internet tool was able to observe usage and task accomplishments of subjects. We used these observations to learn characteristics about tool usage and to compare computer-recorded and self-reported data. These comparisons allow us to evaluate the Internet tool as a data collection device.
