The implementation of Good Practice in Hospital Food and Nutrition Units is necessary due to the intense production and food handling to ensure safe food for hospitalized population, especially in times of agreement term trading. This study aimed to compare by applying check-list the adequacy levels of Good Handling Practices in a Power Unit Nutrition, monitoring the transition of a lease agreement in a UAN in a Hospital Unit in Rio de Janeiro. It was applied a check-list semi-structured response options "AS" and "NOT AS" for 29 days in the management of two contracts (COMPANY A and COMPANY B) taking into account the good manufacturing practices based in the DRC 275, considering 44 items of observation, distributed among personal hygiene of food handlers; environmental hygiene, structure and facilities, waste management, integrated vector management and pest and food production. There was non-conformities in all items evaluated in both contracts, suggesting a need for continuous training of the handler and investment in structure and modernization of equipment are necessary for the safe food guarantee the health of the hospitalized population.


To get high efficiency photodegradation on pollutants under visible light, Pr(III) doped Y2SiO5 upconversion materials and anatase TiO2 nanofilm coated Pr:Y2SiO5 composite have been prepared by using a sol-gel method. XRD and SEM test results indicated that TiO2 nanofilm was well coated on Pr:Y2SiO5 to form TiO2@Pr:Y2SiO5 composite particles with the sizes of 0.5–1.0 μm. To avoid secondary pollution resulting from incomplete recovery of catalyst particles, TiO2@Pr:Y2SiO5 was loaded on the glass fiber filters by using a dip-coating method. It is found that the catalyst particles were embedded into the carrier firmly, even after having been reused for 6 times. The luminescence intensities of TiO2@Pr:Y2SiO5 were getting down sharply with the coating contents of TiO2 increased, which was attributed to the adsorption of the luminescence by the TiO2 film in situ. As a result, TiO2@Pr:Y2SiO5 with 4% TiO2, which presented lowest luminescence intensity, showed the highest efficiency on the photodegradation of nitrobenzene wastewater. The catalysts loaded on glass fiber filters showed excellent reusability on the photodegradation of nitrobenzene and presented a photodegradation rate of 95% at the first time and up to 75.9% even after 6 times of reusing by the treatment time of 12 h.


We describe the percolation model and some of the principal results and open problems in percolation theory. We also discuss briefly the spectacular recent progress by Lawler, Schramm, Smirnov and Werner towards understanding the phase transition of percolation (on the triangular lattice).


The SEG Board of Directors Special Lecture Series, presented by Alfred Liaw, began 27 May 2013 and toured six SEG Student Chapters located in and around the greater cities of Beijing and Qingdao, China. The chapters included China University of Geosciences (Beijing), Institute of Geology and Geophysics of Chinese Academy of Sciences, Peking University, China University of Petroleum (Beijing), CNPC Research Institute of Petroleum Exploration and Development (RIPED), and China University of Petroleum (East China). This lecture series was presented to 264 attendees in four days.


A direct injection nebulizer (DIN) was designed and constructed. It was used in coupling high-performance liquid chromatography to inductively coupled plasma mass spectrometry for the speciation of chromium. Speciation of chromium using a concentric nebulizer and the DIN was investigated. Using a slight modification in the chromatographic conditions, the speciation of chromium was achieved on a microbore column. The absolute detection limit for both CrIII and CrVI was 3 pg. The DIN was used to run the National Institute of Standards and Technology Standard Reference Material (SRM) 2670 Toxic Metals in Freeze-Dried Urine, Elevated Level.


Being older rather than younger than most of one's classmates is presumed to provide benefits to students at least throughout elementary school. The present study investigated this relative age hypothesis among students before and after the transition to middle school with respect to self-esteem, school strain, grade point average (GPA), and anxiety. Partial correlation analyses, with father's education controlled, showed that relative age was associated positively with self-esteem and negatively with strain during fifth and sixth grade. Separate analyses showed these relationships for females but not for males. The influence of father's education was particularly pronounced among the youngest subjects with respect to strain and GPA. Results suggest that the potentially detrimental effects of being relatively young carry on into middle school and that younger early adolescents whose parents have relatively little education are most at risk.


Experimental and theoretical results are presented to show the difference between electron- and hole-initiated avalanches on the microwave properties on impatt oscillators under optical illumination. This difference, arising from unequal electron- and hole-ionisation rates, is demonstrated with X-band Si impatt structures suitable for microwave-optical interactions. A large signal impatt model is extended to incorporate the difference between hole and electron photocurrent, with the intrinsic response time of the avalanche depending on photocurrent composition. The model gives good agreement with experimental results of the power dependence upon photocurrent, although additional power saturation mechanisms need to be considered at higher power levels.


Sensemaking involves numerous levels of processing and logic in order to achieve automated decision support. Many of these concepts derive from the realm of pattern recognition. The data under consideration frequently is observed in a noisy environment and so one of the first steps involves preprocessing the data to suppress noise and isolate the data signal. Patterns within the data are often used to improve signal detection and aid identification of the data in the quest to produce actionable information. A critical step of making sense from raw or partially processed data and other aspects of decision support is to organize information, which frequently involves grouping, partitioning, or clustering objects. However, there is typically an assumption that structure exists within the data, and the number of clusters is a required parameter for many of the clustering algorithms. A common approach to determine the best number of clusters is to iterate across a set of potential values the for number of clusters and evaluate the quality of the resulting clusters using some metric. In this paper, we present an automated approach to detect structure and improve automation of clustering algorithm parameters. We apply our approach to analyze a complex, dynamic multiple edge set network that was used to model call data from the Ivory Coast compiled from France Telecom/Orange anonymized call records over a 5 month period.


Conjugate addition of the chiral formyl anion equivalent p-tolyl p-tolylthiomethyl sulphoxide (+)-(S)-(1) to the cyclopentenone derivative (2a) leads to the adduct (3a) in 45% yield with high diastereoselectivity. Reduction of (3a) gives the dithioacetal (4a), an interesting optically pure intermediate in the synthesis of 11-deoxy-ent-prostanoids. The high selectivity, contrasting with a lower selectivity observed using cyclopentenone, is to be ascribed to more severe steric demands in the transition state.


A ready to serve sandwich paste was developed from the meat of tilapia (Oreochromis mossambicus) with peeled potato by thermal processing in retortable pouches at a temperature of 121.1 o C with different F 0 values of 6,7,8 and 9. Based on the evaluation of samples for texture, colour, commercial sterility, biochemical and sensory analysis all the samples were found to be acceptable based on the quality. The samples processed at 121.1 o C at F 0 value 8.08, Cook value 75.02 and total process time 32.23 min were found to be the best. Thermally processed ready to serve tilapia sandwich paste was developed and its keeping quality was studied at ambient temperature. During storage, there was no significant change in the contents of Moisture, Protein, Fat and Ash. The TBA values of tilapia sandwich paste slightly increased during storage. Tilapia sandwich paste processed at 121.1 o C for F 0

Within this program at regional exhibition MedINFO students of college had provided the action «Learn your blood pressure». During the questioning of the participants and visitors of an exhibition the data confirming a role of major risk factors in the genesis of the arterial hypertension has been received.


based tourism concept has been at the vanguard of the promotion of rural development, both in developing and developed countries (Honey, 2008). According to Cornelissen (2005:21) "the theoretical premises of community tourism have long history, originating from the participatory and empowerment development models that emerged as a new paradigm in development discourse in the 1970s". Community-based tourism has been directly linked to local cultural especially for tourism 'impact' and 'attraction' with astuteness that this special interest tourism should respect local culture and find ways to augment and salvage local culture, environment, and heritage (TelfarS Flacke-Naurdofer, 2008:252).


Virtual material is a dynamic model of mechanical contact surface, which is suitable for finite element simulation. This method can characterize the stiffness and damping of the contact surface well by using fractal geometry theory to describe the contour of the contact surface. Based on standard W-M function, we verify the accuracy of the fractal dimension calculated by wavelet transform, and then fit the fractal dimension of machined surfaces with different roughness. Using the fractal dimension, we calculate the virtual material parameters to establish the finite element model of the unit specimen. Finally, we carry out the experimental modal analysis to examine reproduce the virtual material method.


Honeypots are more and more used to collect data on malicious activities on the Internet and to better understand the strategies and techniques used by attackers to compromise target systems. Analysis and modeling methodologies are needed to support the characterization of attack processes based on the data collected from the honeypots. This paper presents some empirical analyses based on the data collected from the Leurre.com honeypot platforms deployed on the Internet and presents some preliminary modeling studies aimed at fulfilling such objectives.


The last six months have been a time of considerable stress for the staff and the students at this new school . This has been particularly true for those of us who are concerned with the creative arts, crafts and design. We opened in August 1970 with an incomplete building, designed to fulfill the function of an unstreamed upper school and community college. The initial intake was of the order of eight hundred of whom about three quarters were o f middle school age, the rest of first year upper school age. This intake was also far from being homogeneous, not least of all in respect of previous experience in design studies . Although the colle g e has already received much publicity and has, perhaps become the subject of some controversy, there is little that is completely new taking place at Countesthorpe. What i s being attempted, is the putting into practice in one school of many innovations already being carried out in many other places. E ven so, studen t s and staff joining the schoo l find a great deal that seems new and not a little disturbing . It is certainly true that many of our difficulties stemmed from confused expectations of one sort or another .


Interseeding legumes into grass sods increases herbage quality. Interseeding alfalfa (Medicago sativa L.) into bermudagrass [Cynodon dactylon (L.) Pers.] has given yields comparable to grass fertilized with high rates of N. Our objective was to compare forage quality attributes of N-fertilized bermudagrass with alfalfa-bermudagrass mixtures. N rates of 0, 112, 224, and 448 kg ha-~ were applied to bermudagrass monoculture and to alfalfa interseeded into bermudagrass at 20-, 40-, and 60-cm row spacings. Experiments were conducted on a Cecil sandy clay loam (clayey, kaolinitic, thermic Typic Kanhapludult) and a Norfolk sandy loam (fine-loamy, siliceous, thermic Typic Kandiudult) site. Hand-harvested herbage samples were separated into botanical components. Crude protein, acid-detergent fiber and neutral-detergent fiber were measured using a combination of wet-lab and near infrared reflectance spectroscopy (NIRS) procedures. Nitrogen increased the crude protein in bermudagrass monoculture by 11 to 61 g kg-~. The crude protein response of bermudagrass in mixtures to N was slight to nonsignificant. Increasing row spacing of alfalfa reduced grass crude protein by 9 to 23 g kg-~ and had no effect on alfalfa crude protein. Fiber fractions decreased slightly in grass with added N, but fiber in alfalfa was not influenced by any treatment. Yield of crude protein increased with N, particularly in bermudagrass monoculture, but interseeding alfalfa without N produced crude protein yields that usually exceeded those of bermudagrass monocuiture at the 448 kg ha-~ N rate. Interseeded alfalfa, even at wide row spacings, appears to produce enough biological N to replace 448 kg fertilizer N ha- ~ or more in the production of herbage protein in bermudagrass. B ERMUDAGRASS forms a dependable perennial base for many pasture and hay production enterprises in the southeastern USA. There are many well-adapted ecotypes of common bermudagrass (BG), as well improved hybrid varieties. All of these cultivars share the common trait of relatively low forage quality for grasses of tropical origin (Moore and Mott, 1973), especially under mid- to late-summer weather conditions (Akin, 1989). The forage quality deficit derives from high fiber concentration (Mertens et al., 1987) and relatively low crude protein concentration in the absence of high rates of fertilizer N. Alfalfa and other legumes exhibit lower concentrations of fiber fractions and higher protein and digestible energy than grasses (Sheaffer et al., 1990), and have been used to increase forage quality and animal performance on grass-based pastures (Burns and Standaert, 1985). Alfalfa can be established and will persist when interseeded in BG sods (Brown and Byrd, 1990; and Stringer et al., 1994). Yields of interseeded mixtures were equivalent to BG monoculture fertilized with 200 kg ha-1 or more of N. The growing season was lengthened by earlier growth initiation in spring and more active growth in autumn. Bermudagrass persistence Dep. of Agronomy and Soils, P.O.

In the 2011 wave of popular uprisings shaking authoritarian rule in the Middle East, mass societal mobilizations have been the crucial factor. But institutional actors, especially armies, are also playing an active role. Armies in the region have generally had less and less involvement in formal interstate wars and consequently have played more of a role, willingly or not, in underpinning regimes. Recent events demonstrate two patterns: armies that have refused to play this role (Egypt, Tunisia) and armies that have been willing, at least for some time, to answer the regimes' requests to engage in repression (Bahrain, Yemen, Syria) or even civil war (Libya). How can we account for the military's growing role in civil strife or civil peace?


Aim. To study local myocardial contractility (LMC) in patients with coronary heart disease (CHD) and Type 2 diabetes mellitus (DM-2). Material and methods. The study included 144 patients: 70 with CHD and DM-2 (Group I), 74 with CHD only (Group II). To study LMC disturbances, all participants underwent balanced radioventriculography (BRVG). Results. In patients with CHD and DM-2, LMC abnormalities varied from hypokinesia to akinesia and dyskinesia. In this group, comparing to participants with CHD only, the number of disturbed LMC zones was significantly greater in both left and right ventriculi. Conclusion. In CHD and DM-2 patients, who demonstrate the presence of myocardial zones hypokinetic due to chronic ischemia and diabetic cardiopathy, LMC abnormalities of both ventriculi should be timely diagnosed. LM dysfunction reversibility should be assessed in acute nitroglycerin test.


Fatty acyl groups from galactolipids (a lipid found specifically in plastids) and polar lipids (found in all cell membranes) were analyzed in a total lipid extract. (…) Fatty acid unsaturation decreased in the enriched plasma membrane fraction during both paraquat treatment and the hypersensitive reaction. We suggest that O 2 − -initiated lipid peroxidation produced the altered plant cell membrane permeability observed in both paraquat treatment and bacteria-induced hypersensitive reaction


Compositions of matrix glasses from the current eruption of Soufriere Hills Volcano indicate that decompression-driven crystallization results in 20-70 wt % groundmass crystallization during eruption and variable degassing. Variations in crystallinity and volatile contents (water and chlorine) of matrix glasses are attributed to variations in extrusion rates and residence times in the lava dome. Residual water contents in pumice clasts (0.2-0.6 wt %) indicate minimum pressures of 1.1-3.7 MPa in 1997 Vulcanian explosions. Residual water contents of 1.6 wt % in a ballistic block ejected in sub- Plinian explosive activity on 17 September 1996 imply larger pressure drops (similar to20 MPa). Variable residual water contents in dome samples are consistent with pressure variations of up to 9 MPa in the lava dome interior. Large variation in chlorine contents between lava blocks compared with explosion pumice clasts indicates that shallow-level processes dominate degassing. Low melt chlorine contents of dome samples cannot be explained by open- or closed-system degassing, especially when crystallization is taken into account. Instead, heterogeneous chlorine leaching by circulation of groundwater vapour in the dome is proposed. Variable and elevated matrix glass deltaD values can also be attributed to interaction with isotopically heavy surface waters. HCl emission during the current eruption can be accounted for by Cl loss from the melt, consistent with the melt being undersaturated in chlorine.


Composite support structure of continuous arch internal support is a new type of maintenance structure of deep foundation.

Engineering examples of composite support structure of continuous arch internal supporting in deep excavation engineering applications are analyzed and summarized. At the same time, the design parameters are provided for more engineering applications.


Two different behavioral circuit models are proposed in this paper, one for the data clocked retimer and the other for the reference clock driven retimer. Instead of two or more piping simulations, the proposed retimer behavioral models can be used in any general purpose transient simulation tools by a single transient simulation. The proposed retimer behavioral circuit models are in a sub-circuit form and can be used directly and independently. The retimer behavioral circuit models include several new building block models such as a behavioral circuit model of signal rise-fall edge trigged latch, a behavioral circuit model of the reference clock driven latch, a behavioral circuit model of the CDR based on the jitter transfer function of the applied clock architecture, a behavioral circuit model of the lossy clock channel, and a behavioral circuit model of the clock frequency N-multiplier. The proposed retimer models also include some existing models such as a behavioral circuit models of a time-domain jitter to data stream modulator, a bidirectional single-ended-mode to mixed-mode transformer, and behavioral circuit models for CTLE, DEF, and pre-emphasis Tx. To include the low frequency periodic jitter, a time-frequency scaling method is proposed to use a much shorter circuit time for affordable signal integrity transient simulations. The transient circuit simulation for eye-diagram by using the proposed retimer behavioral circuit models can include the periodic, ISI induced, and crosstalk induced jitters in signal and/or clock channels. The proposed retimer behavioral circuit models are tested in transient circuit simulation on packaging systems including active twinaxes and on printed circuit board wires. No convergence problem appears during the test simulations. The simulation results look reasonable and have been verified by different methods.


Automatic fusion of different kinds of image datasets is so intractable with diverse imaging principle. This paper presents a novel method for automatic fusion of two different images: 2D hyperspectral images acquired with a hyperspectral camera and 3D laser scans obtained with a laser scanner, without any other sensor. Only a few corresponding feature points are used, which are automatically extracted from a scene viewed by the two sensors. Extraction method of feature points relies on SURF algorithm and camera model, which can convert a 3D laser scan into a 2D laser image with the intensity of the pixels defined by the attributes in the laser scan. Moreover, Collinearity Equation and Direct Linear Transformation are used to create the initial corresponding relationship of the two images. Adjustment is also used to create corrected values to eliminate errors. The experimental result shows that this method is successfully validated with images collected by a hyperspectral camera and a laser scanner.


This paper proposes an experimental approach for diagnosis of adjacent and nonadjacent broken bars in induction motors, particularly in low-load and absolute no-load conditions, since it is very difficult to detect broken bars when the motor is operating at very low slip or under no load, using the traditional current signature analysis method. This study took into account the use of Fast Fourier transform to analyze the resultant magnetic flux density in a low-cost Hall Effect sensor installed between two stator slots. The amplitudes of harmonic components have been evaluated, in order to identify adjacent and noncontiguous breakage bars around the rotor structure. Experimental results obtained on a 7.5kW squirrel cage induction motor are presented and discussed.


Cement-bentonite (CB) cutoff walls have long been used to control ground water flow and contaminant migration at polluted sites. Hydraulic conductivity and unconfined compressive strength are two short-term properties often used by industry and owners in CB specification and are important parameters discussed in this paper. For polluted sites, long-term compatibility is also an important issue. These properties are coupled to a number of external factors including the mix design, construction sequence, presence/absence of contaminants at the site. Additional short-term properties for engineering assessment include the stressstrain characteristics in both drained and undrained shear in both with and without confinement as well as one-dimensional consolidation properties. Long term CB properties are affected by aging, reaction chemistry, drying, in situ stress state, and interaction with the polluted environment. © 2013 Taylor & Francis Group.


The state of alarm decreed due to COVID-19 has resulted in significant regulatory production with special incidence on the constitutional right to work. The fundamental criterion that has guided the labor regulations, as well as the numerous interpretative instruments that have accompanied it, has been the maintenance of employment and the protection of the most vulnerable groups, as well as the network of social services that have supported citizenship in a crisis unprecedented in recent history.. The weight of the circumstances, in turn, has caused notable deficiencies in the legislative technique and affected some structural deficiencies in the labor market in Spain. The crisis in the care system has been the main one. On the other hand, some of the solutions adopted, such as remote work or certain flexibility tools in the development of productive activity, would require a consensual structural arrangement capable of projecting them into the future.

It is well known that millimetre wave systems can penetrate poor weather and battlefield obscurants far better than infrared or visible systems. Thermal imaging in this band offers the opportunity for passive surveillance and navigation, allowing military operations in poor weather. We have previously reported a novel real time mechanically scanned passive millimetre wave imager operating at 35GHz and in this paper a 94GHz variant will be described. This 94GHz imager has a field-of-view of 60° x 30° and has diffraction limited performance over the central two thirds of this field-of-view. It is relatively inexpensive because the scene is imaged using a linear array of direct detection receivers and compact folded optics. The receiver array has been constructed using indium phosphide monolithic microwave integrated circuits (MMICs) allowing high gain and low noise figure to be achieved. The compact optics consist of a polarisation sensitive mirror and a Faraday rotator. readily The mirror is constructed from expanded polystyrene, supporting a printed copper grid etched onto a PTFE/glass fibre substrate. These materials are low cost and readily available. The Faraday rotator is made from a commercial grade plasto-ferrite sandwiched between antireflection coatings. The optics produce a conical scan pattern and image processing is used to generate a raster scan pattern and to perform gain and offset corrections.


Twenty four reservoirs in Central India were investigated for their physical, chemical and biological features. These reservoirs differed significantly in their size, physical features, chemical composition and vegetation. Three medium and major reservoirs recorded comparatively low electrical conductivity. All the eighteen minor reservoirs showed high conductivity and low transparency since they were all situated in densely populated urban areas polluted by human faeces and domestic sewage. The most abundant ions in water are calcium, carbonate and chloride. The phytoplankton was found to be dominated by Cyanophyceae. Rotifers dominated among zooplankton. All the minor reservoirs are highly eutrophicated. Among the major reservoirs Tawa Reservoir is oligotrophic while others are mesotrophic to eutrophic in nature.


To achieve human–vehicle hybrid-augmented intelligence, this study proposes a hierarchical human-vehicle collaboration control strategy (HVCCS) based on human-cyber-physical systems (HCPS) architecture. In the upper layer, virtual human module is established based on fuzzy feedback control that can respond to physical scenes. Further, the combination of outputs from the established module and the preceding vehicle's speed can generate the referenced velocity in cyber space for the lower layer. In the lower layer, an H-infinity full-state feedback control considering the uncertainty of vehicle dynamic parameters is designed, which can facilitate the autopilot system (AS) to achieve fast and stable tracking of the reference velocity. Numerical simulation results demonstrate that the proposed scheme can improve the stability and safety of the car-following behavior, and ease the operating load of driver.


Downtown area was traditionally the main shopping space of urban residents. However, the role of retailing has clearly diminished in the center of Western cities since its heyday in the 1920s. This trend was caused by violent transformations in the economic, social and locational context, which involves residential suburbanization, as well as new forms of commercial development out of town. In transforming China, under much similar urban-developing route, the retail decentralization has also presented itself in many cities. Several earlier researches have analyzed such phenomenon from their macroscopical perspective, which paid much attention on the physical development of urban retailing out of town. To date, however, limited studies choose the approach of consumer behavior, the other side influence of commercial space, to reflect the temporary retailing change. What's more, compared with suburban commercial development, there's seldom focus on the factual situation of downtown area. The present research investigates the residents' utilization of both traditional and rising new commercial centers with different types of retailing form, which aims at making clear the change of residents' shopping behavior, especially spatial transformation, in such quite a different retailing context and in turn its reflection of and impacts on urban commercial space. The questionnaire survey was carried out among typical residential areas distributed different location of Beijing. Particularly, the residents' utilization and related problems of downtown retail center is discussed in this paper. Study results showed that downtown retailing still plays important part in residents shopping activity. However, with rapid urban sprawl, retailing in urban center has greatly threatened by booming out-of-town commerce. Average month frequency and average expend per time of consumers in downtown retailing centers overwhelms that in suburban retailing centers, the trend of which is much more obvious as to suburban residents. The preponderant consumer groups of downtown retailing is the old and the young, who are both weak in purchasing power; while suburban areas can draw groups of different age, occupation, income, residential location, and those with strong power tend to make more use of such new retailing centers. Besides, take the increasing use of private car into account, the difficulty of retailing of downtown may be exacerbated too. Among three of the old centers, Qianmen showed its lost of commercial vibrancy more evidently and it will probably change its role for residents' shopping totally. The research also discovered that retailing located in inner city began to experiencing badly decline that once appeared in Western cities, which was also an important evidence of the change of commercial space. Finally, the paper emphasized the need to further discuss on this topic, combining it with current change of urban population distribution, urban spatial structure, urban life and its space, as well as the preference of urban consumers.


URACIL ACCUMULATION RESPONSE TO FOLATE DEPLETION IS A FUNCTION OF DNA REPAIR IMBALANCE THAT MAY BE A MECHANISM OF AGING by Hongzhi Ma August 2014 Advisor: Dr. Diane Cabelof Major: Nutrition & Food Science Degree: Doctor of Philosophy Folate is an essential nutrient for humans. They carry and transfer one carbon units. They have important biological functions during many reactions, like DNA synthesis, RNA synthesis, DNA methylation, DNA repair, cell division and growth. Through biochemical techniques to determine the gene expression, enzyme activity, uracil level in DNA, and through microbiological assay to determine the folate level, elucidates mechanism of uracil accumulation response to folate depletion. The findings present how folate deficiency status affects the uracil DNA glycosylase activity, and uracil initiated DNA base excision repair. DNA repair ability decides whether there is uracil accumulation under the folate depletion condition in different cell lines. Further, there is uracil accumulation in the mice colon tissue found under the aging condition.

The informal vocational learning experiences of 13 young Australians preparing for the transition from school to work were examined. At the time of their interview, all 13 youths were students at a hybrid educational site in the Sydney metropolitan area that allows students to combine general education with vocational qualifications and experience in the workplace. The youths responded to an advertisement for research volunteers who had a clear vocational goal and believed they were engaging in activities designed to increase their opportunities for gaining employment in their desired area. Although the respondents' stories reflected a wide range of patterns of activities, they also contained several similarities. All students interviewed had changed their place of education at the end of year 10, and all chose to transfer to an educational institution offering a hybrid approach to postcompulsory education and training. All were aware of the importance and desirability of preparing for a range of career options. Despite being vocationally goal-oriented, many participants were unable or unwilling to articulate anything but a vague concept of "pathway." All participants had workplace experience in their area of vocational interest, and all considered exposure to work in their chosen industry a valuable experience. (Contains 24 references.)

The intermolecular interaction determines the photophysical properties of the organic aggregates, which are critical to the performance of organic photovoltaics. Here, excitonic coupling, an important intermolecular interaction in organic aggregates, between the π-stacking graphene quantum dots is studied by using transient absorption spectroscopy. We find that the spectral evolution of the ground state bleach arises from the dynamic variation of the excitonic coupling in the excited π-stacks. According to the spectral simulations, we demonstrate that the kinetics of the vibronic peak can be exploited as a probe to measure the dynamics of excitonic coupling in the excited π-stacks.


With the Multi-Pollutants Protocol and the NECs Directive, the United Nations Economic Commission for Europe and the European Commission, respectively, have presented new regulations for the limitation of the emissions of major air pollutants, which in Germany and elsewhere have created considerable pressure to take further measures. The centrepiece of these new regulations are national emission ceilings (NECs) that are linked to specific environmental targets and to be attained by the year 2010. The interesting aspects of these NECs are the capping of national emissions and the way in which the associated emission rights have been allocated. Part 1 of this paper provides relevant background information, focusing in particular on the methodology used to allocate emission rights. Part 2 deals with the requirements laid down in the Multi-Pollutants Protocol and the NEC Directive and discusses measures that could be taken in Germany to comply with them.

Aedes aegypti is currently widespread in Bolivia. Although these mosquitoes commonly inhabit tropical and subtropical areas at low altitudes, recent studies found them up to 2,500 meters above sea levels (m.a.s.l.). The study's objective was to identify the presence of the Ae. aegypti mosquito in urban areas with altitudes around 2,900 m.a.s.l. in Sucre, Bolivia. For this, ovitraps were installed at 12 points, and a morphological and taxonomic analysis was performed. The presence of mature and immature forms was confirmed in 3 of the 12 sampling points. Entomological indexes reported: House=13.64, Breteau= 27.27, dry containers= 43.55, containers with water =56.45. Reproductive populations of Ae. aegypti was confirmed to more than 2,900 m.a.s.l. in an urban area with a high migratory flow area. It increases the risk for autochthonous cases of Dengue Disease in the short term. Prevention and control strategies must be intensified to reduce the transmission of mosquito-borne diseases.


Desmoid tumour is an histological benign tumour. Nevertheless, peri-scapular relapses can decrease the function and intra thoracic progression threaten life. To prevent these complications, damaging treatment (radiotherapy, amputation) are sometimes proposed. To precise the optimal indications of treatment, we reviewed our cases. Patients: from 1984 to 2008, we treated 11 patients with peri-scapula fibromatosis (mean age 42 (13–58)). Only 4 patients were seen at first hand, 7 for relapses (3 of them after radiotherapy). Treatment was adapted to each patient, in function of age, history of illness, and risks of spontaneous evolution. En bloc extratumoral resection was performed each time, when it didn't expose to heavy functional risk (8). The other patients were treated by contaminated resection, but never invaliding. 4 patients received pre or/and post-operative chemotherapy. 1 received Interferon alpha, and 7 tamoxifen. Results: with a median follow-up 15 years 3 months, 7 patients suffered of recurrence. No patient died from disease (thoracic complications) or therapeutic complication9 patients are in complete remission and 2 in stable disease. Following radiotherapy, local relapses (7 cases) and repeated surgery, functional sequellaes are numerous: 2 circumflex nerve palsies, 3 articular stiffness. Major functional sequellaes came from radiotherapy (limb discrepancy, lung and thorax deformity, skin and muscle atrophy. Conclusion: in this non predictable illness, therapeutic indications should individually balance risks of spontaneous evolution and of complications of treatment. Besides surgery, needed in fast all cases, but often insufficient, it must be considered the value of interferon, tamoxifen and/or chemotherapy. The most important concept is the necessity to treatment avoiding late sequellaes and particularly radiotherapy or mutilating surgery.

Abstract Low-energy beaches are omnipresent coastal features. In total, their overall length greatly exceeds that of ocean shorelines throughout the world. However, a comprehensive understanding of low-energy beaches is lacking, with their dynamics generally considered under existing principles governing open ocean beaches. This study investigates the morphodynamic characteristics of very low energy beaches on which wave heights can be less than 0.15 m under nonstorm conditions, as distinguished from the characteristic of high-energy environments in which low energy states commonly have modal wave heights of 0.5–1 m. This investigation is achieved through an analysis of a 30-year profile data set for Cockburn Sound, a fetch-limited, low-energy basin in southwestern Australia. The Sound experiences the full ranging of microtides and surges of the region, together with locally generated wind waves. Recurring patterns in cross-shore geometries and their distribution were identified through regression analysis of mean profile shapes. The spatial variability in the wind-wave regime was established by hindcasting conditions for key fetch directions. Cluster analysis of profile and environmental variables identified four morphotypes. Each morphotype can be explained in terms of a simple exposure factor, Ef = log(Fl/Ms), which is the proportion of fetch length (Fl) to marginal shoal width (Ms), such that Ef < 1 was characteristic of exponential profiles, Ef = 1–1.5 of segmented profiles, Ef = 1.5–2 of concave-curvilinear profiles, and Ef > 2 of convex-curvilinear profiles. Thus, the exposure factor is identified as a useful nondimensional parameter for the delineation of low-energy profile morphotypes within the study area. The utility of this approach in widespread classifications of low-energy beach morphology requires further research. This should take place in a variety of environments with varying degrees of protection and shelter from swell and subject to different tidal ranges and fluctuations in sea level.

Objective
To evaluate the wall thickness and inner diameter of arterial branches at portal area of biliary atresia (BA) and seek its clinical correlation.

Methods
From June 2012 to March 2014, 49 BA children undergoing Kasai procedure at our hospital were included. And the characteristics of arterial branches were morphometrically evaluated. And the controls were patients with intrahepatic cholestasis (n=10). The follow-up period was at least 6 months. They were divided into excellent, favorable and unfavorable groups. According to the age at Kasai procedure, they were divided into ≤60 days, 60-90 (includ 90) days and >90 days groups. The relevance of age during Kasai procedure, short-term prognosis and hepatic arterial branch morphology was analyzed statistically.

Results
The authors evaluated 182 arterial branches (152 in BA, 30 in controls). The arterial wall thickness of portal area was (83.58±28.30) and (72.13±16.59) μm respectively. And the inner diameter of arterial branches was (136.32±52.64) and (113.94±41.94) μm respectively. The arterial wall thickness of excellent, favorable and unfavorable groups was (83.03±29.42), (78.16±25.06) and (87.00±28.61) μm respectively. The inner diameters of arterial branches were (138.92±52.96), (125.81±45.04) and (138.88±56.00) μm respectively. The arterial wall thickness of ≤60 days, 60-90 (includ 90) days and >90 days groups was (87.02±23.66), (81.07±29.94) and(83.08±31.60)μm respectively. The inner diameter of arterial branches was (148.27±54.11), (126.13±47.97)and (137.16±56.07) μm respectively. The arterial wall of BA cases was thicker than that of infants with intrahepatic cholestasis (P=0.038). The branches of hepatic artery were dilated in BA cases (P=0.026). There was a significant positive linear correlation between arterial wall thickness and inner diameter of arterial branches at portal area. Short-term prognosis was not associated with morphological changes of hepatic arterial branches. No statistical difference existed between age during Kasai procedure and changes of arterial branches at portal area.

Conclusions
In BA, thickening of arterial wall and dilation of arteries may be found in periportal area. And a significant positive linear correlation exists between arterial wall thickness and inner diameter of arterial branches at portal area of BA.

Analysis of clinical efficacy of combination of inkretinomimetik exenatid and metformin from 30 type 2 diabetes mellitus complicated by neuropathy and hepatic steatosis. For generalization conditions of patients used standard questionnaires neuropatic complaints and ehogepatodensitometria. After a 12-week course of treatment of distal occurrence demonstrated the degree of polineuropatia in patients with diabetes mellitus type 2 and dyslipidemia decreased significantly: on the scale of the dysfunctional neuropatia accounts with 37,9% to 8,2%, on the scale of the modified dysfunctional neuropatia account – with 41,4% to 6,9%. The positive dynamics was observed in almost all clinical-neurological performance scale NTSS-6. Changes ehogepatodesitometria rates after treatment showed decreasing deposition of fat in the liver. It is proved that in addition to control glycemia in the use of combination therapy for 3 months has a positive effect on the distal sensory-motor polineuropathy and hepatic steatosis.


The Phase Inversion Temperature (PIT), is a concept introduced by Shinoda et al. in the 1960's [1] that corresponds to the temperature at which th e hydrophilic/lipophilic character of nonionic surfactants, in particular polyethoxylated alcohols (CiEj's), changes by dehydration of the polyoxyethylene units, inducing a phase inversion f rom O/W to W/O emulsion on heating. Although PIT is limited to nonionic surfactants and to the temperature range i which water is liquid, it takes into account all formulat ion parameters and it is based on a precisely defined experimental  methodology. The PIT value is attained close to the T* temperature, i.e. when the affinity of the surfacta nt for oil and water are the same.

To be precise, the flow of a viscous incompressible fluid which occupies a bounded domain of R3 is studied. The velocity u and pressure p are assumed to satisfy in this domain Ħ either the stationary Stokes equations:


Introduction. Improving the quality of surgical resections by evaluating surgical specimens is probably the most important feedback a surgeon can receive. Moreover, prognosis of patients with colon cancer is based on achieving appropriate resection margins and assessment of lymph node status. For these reasons we aim to provide a retrospective analysis on colon cancer specimens operated by a single surgical team. Materials and Methods. 88 patients operated between 2013 and 2016 were included in the study. Data were gathered prospectively and assessed by multivariate analysis for the main variables (age, gender, tumor staging, specimen length, distance to closest resection margin, number of lymph nodes, and number of positive lymph nodes). Results. The mean number of lymph nodes excised was 31,9, with more after right colectomies (39.6) than after left colonic resections (29.1). The average specimen length was 29.2cm after right colectomies, 35.6cm after left hemicolectomies and 18cm after segmental colectomies. There was a significant correlation between the number of lymph nodes, specimen length, and age of patients. Conclusion. Lymph node status is correlated with specimen length and age. The standard of 12 lymph nodes was achieved and surpassed, being comparable to the benchmark literature. Standards on colon resections need to be reevaluated as many surgeons are pressured by quality measurements which do not always reflect sound oncologic principles. Stefan Morarasu et al. 76 Introduction The number of lymph nodes excised in colon cancer surgery has been found to be critical to the overall survival rate of patients (1, 2). Besides their staging role, the number of lymph nodes correlates with KaplanMeyer survival curves. Surgeons with proper lymph node yields have better prognostic outcomes than surgeons with statistics below standards values (3, 4). The importance of extensive lymph node resection is not based on the therapeutic role but rather on the diagnostic and staging significance, as more lymph nodes in the specimen will lead to better staging and subsequently improved treatment for patients (5-9). A total of 12 retrieved lymph nodes are considered the standard of care. Variation in the numbers of retrieved nodes has been analyzed, and many factors have been proposed to influence the number of excised lymph nodes, including age, sex, tumor location, tumor stage, and the technique used for pathological assessment (10, 11). Perhaps the most important factor influencing appropriate lymph node excision is the surgeon him/herself. Technique of dissection, maintaining the correct anatomic plane, and central vascular ligation are all influencing factors that depend on the specific surgeon. Following anatomical planes in the course of dissection is imperative for proper specimen retrieval, an idea supported by Total Mesorectal Excision (TME). Heald (12) has thoroughly described the correct excision plane in rectal surgery, with such specimens proving far superior to previous ones (13). The logic of TME lies in respecting the embryological, avascular plane between the mesorectal and pelvic fascia, and with the advent of TME, rectal surgery has now become standardized. However, these planes may not be limited to the rectum, but rather can be found all along the colon such that Complete Mesocolic Excision (CME) has now been promoted as the standard surgical technique in colon surgery. Proponents of CME present superior lymph node counts and better oncological outcomes when CME is followed (14-17). Others argue that CME is simply a D3 lymphadenectomy, which Japanese and Taiwanese surgeons had already been doing before CME was proposed. Even so, the necessity of a standard procedure in colon surgery is obvious and underscored by the variability of lymph node retrieval and specimen length among surgeons worldwide. Comparative studies of specimens before and after adopting CME by the same surgeons show superior outcomes under the latter conditions. Regardless of the procedure, CME or D3 lymphadenectomy, correct dissection, central ligation, respecting oncological margins, and retrieving a proper specimen are critical for all the lymph nodes identified for excision. Evaluating the specimen is based on the number of lymph nodes excised, as the number of lymph nodes is an independent prognostic and staging factor in colon cancer. For these reasons, a thorough review of one`s specimens regarding lymph node count is or should be a must for improving surgical standards. Materials and Methods We conducted a prospective study of patients diagnosed with colon cancer between 2013 and 2016 who were operated by a single surgical team at the 2nd Surgical Unit, Regional Oncology Institute, Iasi, Romania. Data were prospectively collected in an excel database and included age, sex, operation date, intraoperative diagnostic and findings, preoperative staging, preoperative radio-chemotherapy, preoperative CEA and CA19-9 values, and histopathology report (histologic diagnosis, pTNM, specimen length, distance to resection margins, number of lymph nodes and number of positive lymph nodes). Only patients that had all the aforementioned details were included in the study. Postoperatively, patients were followed up at 3, 6, 12 months and annually thereafter by tumor marker levels, abdominal ultrasound, chest x-ray, and CT scans. Patients were called in for control to assess possible local recurrence and overall survival according to the Institute's follow-up protocols. Data were grouped according to the type of procedure the patients underwent: right hemicolectomy, left hemicolectomy, segmental sigmoid resection, and transverse segmental colectomy. Rectal cancer cases were not included in the study. Specimens were measured after formalin fixation. No special techniques were used to harvest lymph nodes (e.g., fat clearance, blue dye injection). Multivariate data analysis was performed in Microsoft Excel using a logistic regression model; p<0.05 was considered statistically significant. Lymph Node Ratio (LNR) was calculated, defined by the ratio between positive lymph nodes and the total number of lymph nodes excised. Interquartile Range (IQR), mean, and min and max values were generated.


In this paper, we develop nonparametric density estimation for nonnegative data, using Amoroso density as the kernel. It is shown that the resulting Amoroso kernel density estimator is free of boundary bias, having the mean integrated squared error (MISE) of order O(n−4/5), as in other boundary-bias-free density estimators from the existing literature, where n is the sample size. Further, we discuss the bias-reduced Amoroso kernel density estimators, having the MISEs of order O(n−8/9). We illustrate the finite sample performance of the Amoroso kernel density estimator and its bias-reduced versions, through the simulations.

Abstract : The FLB-10 provirus represents a full-length molecular clone derived from SIVmac 251 simian immunodeficiency virus. The molecularly cloned virus is replication-competent in vitro and is cytopathic for CEMX174 lymphocytes and primary macaque peripheral blood lymphocytes. Complete nucleotide sequence reveals that the FLB-10 clone contains mutations compromising expression of the vpr, nef and env genes. Therefore, vpr an nef gene products are not necessary for the in vitro replication or cytopathic effect of SIVmac. Virus stocks were inoculated into several cynomolgus monkeys and one juvenile rhesus macaque. While none of the cynomolgus monkeys have developed an infection over one year post-inoculation, the injected macaque became infected and developed a fatal immunodeficiency syndrome. These results will stimulate further studies with larger numbers of animals to address whether vpr or nef reversions occur to allow in vivo SIV replication.

The low rank coal, especially brown coal has a highly hygroscopic and unstable property, so JIS method could not be applied to such a coal.In direct gravimetric method we found that the cause of difficulity to get constant weight may be attributed to adsorption or desorption of oxygen gas and the passing of the inert gas containg the moisture brings about the activiation ofabsorber which also results the difficulity to get constant weight.So we have established the improved gravimetric method to get correct value, whichis comprised by two factors, one is passing of the inert gas containing moisture to heated copper oxide zone before the absorption of moisture by absorber, and the other is passing of the dry oxygen gas to absorber to get the constant weight. The sequential analysis of moisture, hydrogen and carbon of browncoal was achieved by this improved method.In drying method, we established the improved method comprised of using modified apparatus of Abderhalden's drier and introducing helium gas.


Nannochloropsis salina (N. salina) has recently received growing interests as a sustainable source of high‐value bioproducts. As the illumination condition could be manipulated to affect the microalgae activities in indoor cultivation, in this study, kinetic models were developed to describe the growth and bioproduct formation in N. salina under different illumination conditions. Being continuously exposed to white (380–760 nm), blue (430 nm), red (680 nm), and mixed blue/red light, the growth of N. salina was assessed over the course of 12 days incubation and the evolving cell densities, lipid, and carbohydrate concentrations were recorded. Kinetic models were then used to fit the experimental results and describe microalgae behaviors with respect to illumination conditions. The highest growth rates were recorded when the microalgae were exposed to the blue/red light, leading to 0.8 g/L standing dry biomass. Also, although lipid and carbohydrate productions were stimulated under other illumination conditions, the advanced biomass production achieved by blue/red light resulted in the highest lipid and carbohydrate productions. As confirmed by the kinetic models, the results obtained in this study revealed that the light absorbed by the photosynthetic pigments of N. salina could be manipulated to not only control the microalgae growth, but also its biological activities, including carbohydrate and lipid productions. Therefore, a two‐stage process would be recommended for lipid and carbohydrate production by N. salina.


Abstract : A preliminary study indicated that young rats have a greater resistance to acceleration stress of 20 positive G than do more mature rats. The present study compared the tolerance of onemonth old rats with three-month old rats at 20 positive G and found that there was a significant difference in favor of the one-month old animals. Twenty rats, which survived the initial centrifugation at one month of age were retested at three months and showed no significant difference in tolerance when compared with control rats on the same age.

It can be concluded that the ethanol extract of avocado seeds has antifungal activity against. Trichophyton rubrum ATCC 28188, Epidermophyton floccosum ATCC 50266 and Microsporum canis ATCC 32699 The greatest antifungal activity was against Microsporum canis at a concentration of 75% with a diameter of 13.4 mm in the strong category


Through-the-wall imaging (TWI) is a challenging problem, even if the wall parameters and characteristics are known to the system operator. Proper target classification and correct imaging interpretation require the application of high resolution techniques using limited array size. In inverse synthetic aperture radar (ISAR), signal subspace methods such as Multiple Signal Classification (MUSIC) are used to obtain high resolution imaging. In this paper, we adopt signal subspace methods and apply them to the 2-D spectrum obtained from the delay-andsum beamforming image. This is in contrast to ISAR, where raw data, in frequency and angle, is directly used to form the estimate of the covariance matrix and array response vector. Using beams rather than raw data has two main advantages, namely, it improves the signal-to-noise ratio (SNR) and can correctly image typical indoor extended targets, such as tables and cabinets, as well as point targets. The paper presents both simulated and experimental results using synthesized and real data. It compares the performance of beam-space MUSIC and Capon beamformer. The experimental data is collected at the test facility in the Radar Imaging Laboratory, Villanova University.

It is shown that the general scalar tensor cosmologies may explain all the current cosmological observations without the need of invoking any ad hoc missing energy density. The explanation is based entirely on the internal dynamics of the theories. Two important predictions of the present analysis are: the universe is tending towards a matter dominated state with the dimunition of the dark energy component and the acceleration of the universe, if any, is slowing down with time.

Opioids, although effective postoperative analgesics, are associated with undesirable side effects. To determine whether nonopioid medication would reduce the amount required for postoperative analgesia, the efficacy of ketorolac, an injectable nonsteroidal anti-inflammatory drug, was studied in ambulatory patients undergoing gynecologic laparoscopy. Patients were randomized to a treatment group (n = 49) or control group (n = 50), then studied using a prospective double-masked design. Intraoperatively, the ketorolac treatment group received a 60-mg intramuscular injection of ketorolac; the control group received an injection of placebo (0.9% sodium chloride). Anesthetic management, postoperative pain, and the management of nausea were standardized in the two groups. Postoperative pain was treated with incremental doses of fentany125 pg intravenously. Nausea and vomiting were treated with droperidol or prochlorperazine. Pain and nausea assessments were done every 30 minutes in the postanesthesia care unit (PACU), at discharge, and at 24 hours after discharge. Postoperatively, for the first hour in the PACU, visual analog scale pain scores, as well as verbal pain scores, were statistically significantly lower in the ketorolac treatment group. Similarly, the severity of pain was twofold less in the ketorolac treatment group than in the control group. Less fentanyl was required in the ketorolac group (26 f 20 pg, mean + SD) compared with the control group (56 + 32 pg, mean + SD). However, there were no significant differences between the two groups with respect to postoperative sedation or nausea, although the incidence of vomiting requiring treatment was higher in the control group. There was high overall satisfaction of patients in both groups. In conclusion, intraoperative administration of ketorolac resulted in fewer patients awakening in pain and in a decreased need for opioid analgesic in the postoperative period. Ketorolac is an effective alternative to opioids for the control of postoperative pain in patients undergoing gynecologic laparoscopy.


Thus, this book does an excellent job of explaining the complexities of the authors' theories on negotiating adult– child relationships. However, this book is not a replacement for a more general textbook on research in early childhood settings. Rather, it provides new perspectives to consider for researchers both inside and outside of the field of early childhood research. In addition, this text would provide supplemental reading options for doctoral courses in qualitative research methods, particularly relevant for those students interested in early childhood education.

In an era of sophistication, 5G technology is considered to be able to encourage the development of the service industry, one of which is the use of the online transportation ordering application (Gojek). The range of the network used will be further increased, so that the application will be more and more in demand. To find out the user's assessment of the system, it is necessary to analyze user services for the Gojek application using the ITIL V3 framework. Focusing on the design service domain which consists of sub domains namely design coordination, service catalog, service level management, availability management, service design process, capacity management, information security. The results of this study show that the average value of the subdomain is 3.65, with the largest current maturity value in the service catalog subdomain, which is 3.75. In the design coordination subdomain, there were 3.72, capacity management was 3.70, in the service level management subdomain was 3.60, information security was 3.64, availability management was 3.58, and service design process was 3.50. it can be concluded that all subdomains occupy maturity level 4, namely manage and measurable, which means that the Gojek application is running well. However, it still provides recommendations for system improvements in the future.


Hemans's poems insistently celebrate the emotional gratification produced by a loving home. Hemans frequently employed the image of the circle as the constitutive figure for the desired home, for, even as Hemans consistently represents the home as an earthly paradise, she constructs this home as an absent space. However, her lyrics need not to be read as single statements, no matter how much her poetry constantly reminds one of the fragility of domestic ideology.
Traditionally viewed as the poetess, Hemans was widely read and celebrated in the nineteenth century. By the close of the century, however, her reputation as a poet began to decline. Fortunately, the past twenty years have brought renewed critical scrutiny to Hemans's poetry challenging the understanding of the role of women and the nature of poetry within the nineteenth-century. In Records of Women, almost all of Hemans's heroines are separated from those they love. Of the many of the poems in this collection, "Siege of Valentia" directly addresses the position of women in society, revealing the limitations of domesticity and the tenuous role of the woman artist without rejecting separate-sphere ideology.


This issue of Topics in Early Childhood Special Education presents contributions from four Early Childhood Research Institutes funded through the Handicapped Children's Early Education Program. Researchers in three of the institutes are focusing their work on very young children, usually under the age of 3 years. The questions they address, the procedures they suggest or use, and the conclusions they draw, when reviewed conjointly with those from other investigators exploring early human behavior, suggest that major changes can be anticipated in the way at-risk and handicapped young children are assessed and subsequent alterations in the intervention provided. The shift to the study of handicapped infants can also be seen in the rapidly growing field of developmental psychology, which has contributed to the surge of new publications on infancy. Examples include: Infancy: Its Place in Human Development (Kagan, Kearsley, & Zelazo, 1978); Handbook of Infant Development (Osofsky, 1979, reviewed in this issue); Infants at Risk: Assessment of Cognitive Functioning (Kearsley & Sigel, 1979); Infants Born at Risk (Field, Sostek, Goldberg, & Shuman, 1979); High-Risk Infants and Children: Adult and Peer Interactions (Field, Goldberg, Stern, & Sostek, 1980); Infants at Risk: Assessment and Intervention (Rrown, 1981); Advances in Infancy Research (Lipsitt, 1981); Infants: Their Social Environments (Weissbourd & Musick, 1981); and The Special Infant (Stack, 1982). New journals have also emerged: Infant Behavior and Development; Developmental Review; Infant Mental Health Journal; Physical and Occupational Therapy in Pediatrics; and Early Human Development. Fortunately, many authors have chosen to include in their studies infants who have diagnosed impairments or who are at risk for biological or environmental casualty, thus providing more explicit information for those responsible for nurturing handicapped infants. The research described in the above literature suggests that investigators are modifying their questions to provide more useful data. Although some researchers have continued to focus on describing developmental milestones that typical infants demonstrate at certain ages, others have moved from this static product approach to study the dynamic processes that produce organismic and mechanistic changes in infants. Their focus is not on whether an infant meets a criterion in per-


The current research aims to study the effect of spatial variability of soil moisture and soil heat content on irrigation scheduling of olive trees and tomato plants under drip irrigation system in desert sandy soil of North Sinai Governorate. Field experiment has been conducted in El-Sheikh Zuwaid experimental station in North Sinai during 2011 growing season. The studied area includes two sites: one cultivated with olive trees and the other with tomato crop. Three profiles were examined in each site to verify the spatial variability of soil moisture and three infiltration tests had been carried out. Physical and chemical analyses were carried out for the soil profiles. Meteorological data were collected for the 15 last years of the site as the irrigation schedules were designed for the tested two crops. The measurements of soil moisture and soil temperature were carried out over the studied growth season which lasted to 6 months. The data show the following: 1Infiltration rate (IR) values express the horizontal spatial variability among profiles, while the soil moisture characteristics express the vertical one. 2The intake rate of water into soil is affected by soil texture, plant cover and soil bulk density. The latter influences the water infiltration to soil as the differences reach to double in olive and 20% in tomato. Olive farm gives the lowest IR values while tomato gives the highest ones. 3Soil moisture shows great differences due to the differences in particle size distribution (soil texture), its content increased gradually from March to August coordinated with soil temperature as well. On daily base, the moisture content shows declination through daytime while get maximum levels at night. Meanwhile, soil moisture fluctuations were more detected under olive than under tomato due to the difference in coverage rates for both. So, intercropping of tomato is recommended through olive lines as the assumption has been verified statistically. 4There were positive significant correlations between moisture content and each of available soil moisture, soil temperature and soil heat content under tomato farm. But for olive no significant correlation was found between moisture content and available soil water, but the rest variable were significant. 5Soil temperature increased from March to August, being higher than air temperature from March to May but lower from June to August. Minimum soil temperature was recorded at daytime hours while the maximum were at night time. Soil temperature values were coordinated with soil moisture ones. The soil heat content values show the same trends of soil temperature. 6Some modification on irrigation schedule has been undertaken adjust the soil moisture at desired level of depletion, where two calculations had been carried out: aModifying the depletion level to compensate the loss of water curve, so, creating new irrigation intervals. bBack calculation using the new intervals reaching to new crop coefficient (Kc). Modifications for olive from 14 – 25 to 11 – 22 days with the same irrigation amount, for tomato from 3 – 7 to 2 – 5 days with the same irrigation Abdel Rahman G. et al. 940 amount, but with modifying Kc for the modified intervals the gross irrigation amount change from 1029 to 1177 and 2404 to 2678 m 3 /fed/season for olive and tomato, respectively. 7Significant positive correlations were found between available soil water and irrigation scheduling for both olive and tomato crops. 8Intercropping hypothesis was checked statistically and the resulted relations were all significant. The work concludes the importance of spatial variability of soil characters and their effect on irrigation scheduling. Furthermore, the back calculation for adjusting the soil moisture regime could be resulted in new irrigation intervals and Kc values. Also, the concept of intercropping under such similar conditions is quite acceptable.


This study is an exploration of the Internet as a new medium for both poetical content and its surrounding paratext, focusing on certain less common, yet rather successful reception politics and (user) profiling strategies used by Romanian contemporary authors and/or publishers of indigenous poetry. Leaving out unspecific, global(ized) book marketing Internet approaches, the present investigation aims to map certain particular, local features and efficient tactics that basically rely on the virtual (i.e., Internet simulated) configuration / reconfiguration of personal and / or group identities, as an adaptation to the new global cybernetic medium and an original response to the "worldwide" virtual networking of both books and identities. A few selected case studies, illustrating different identity construction policies – form straightforward fictional identity generation to subtler, covert alternative group identity design – are described and analyzed as a phenomenon ultimately aiming to build what is generally thought to be a somewhat unlikely bridge between highly cultural content (or forms) and digital mass culture marketing techniques.

Coconut lethal yellowing (LY) is the single most important disease presently affecting the coconut production worldwide. Symptomatic and asymptomatic coconut plants were sampled in some selected areas to verify the identity of phytoplasmas associated with LY in Cuba. Diverse phytoplasma ribosomal groups were detected in the samples from symptomatic palms such as 16SrXII, 16SrVII, and 16SrI. In several other palms 16SrIV-A subgroup phytoplasmas were identified, in the groEL gene the only positive plant from Pilon resulted diverse from the others and identical to the 16SrIV-A strains detected in Jamaica LY infected coconut palms. This is the first record of occurrence of 16SrI, -VII and-XII groups in coconut palms in Cuba.


Abstract 2-Mercapto-3-methyl-1-butanol (2M3MB) imparts an onion-like off-flavor to beer and is known to be formed from 2,3-epoxy-3-methylbutanal (EMB), which is generated in the reaction of iso-alpha acids with oxygen during the hot aeration of brewer's wort. Our previous results revealed that 2-mercapto-3-hydroxy-3-methylbutanal (2M3H3MB), formed from EMB by a nonenzymatic reaction with hydrogen sulfide, serves as the intermediate to 2M3MB. However, little is known regarding the 2M3H3MB to 2M3MB conversion process. In the present study, preparative column chromatography coupled with an enzyme assay revealed that two enzymes of Saccharomyces pastorianus, Old Yellow Enzyme 2 (Oye2p) and alcohol dehydrogenase 6 (Adh6p), are involved in the conversion process. An in vitro reaction containing these enzymes purified from recombinant Escherichia coli cells converted 2M3H3MB to 2M3MB. Furthermore, a yeast mutant with deletion of the genes encoding these two enzymes dramatically decreased 2M3MB formation. Our series of studies has therefore revealed the overall mechanism of 2M3MB formation starting from EMB through 2M3MB.

Traditional filial piety culture includes such aspects as worshiping one's ancestor,treating parents well,having a son to carry on his family name,being loyal to the emperor,bringing glory to one's family and so on.But the basis is to provide for the aged.With the development of the society,people pay little attention on filial culture so the phenomenon of impiety is often seen.The reason is that the ability to carry filial piety has been decreased,and the education function and values have changed.The regression of filial piety culture is good for achieving the purpose of providing for the elderly and the building of harmonious society.The efficient ways are as followed:carrying out filial piety,forming the habit of carrying out filial piety,conducting filial piety at home unintentionally,educating students to carry out filial piety.The whole society makes a jointeffort to develop and expand filial culture.


We follow Bogoyavlensky's approach to deal with Bianchi class B cosmological models. We characterize the analytic integrability of such systems.


1. The variety 'Phulwa' was worked upon for respiratory studies and growth response to dormancy-breaking hormones. The hormones were used in single and double doses. 2. The respiratory studies reveal that ethylene chlorhydrin affects only the bud areas and not the non-bud areas. 3. The intensity of the effect of the hormone progressively decreases in the deeper layers of cells, till finally no effect is visible in the cells of the pith areas. 4. A distinct correlation exists between the respiratory intensity and dormancy. 5. Of the two hormones used the respiratory rates recorded for N. ethylene chlorhydrin treated tubers, given in single and double doses, were the highest. Similarly the growth response to both the doses showed the maximum reduction of the dormancy period, o-1 N. ethylene chlorhydrin treatments were not effective in breaking the dormancy or in significantly altering the rate of respiration. 6. Treatments with 0-5 per cent, ammonium thiocyanate given in single dose showed the lowest respiratory rates and the germination records showed no differ ence over the control. With the double dose a gradual rise in the respiratory rates was observed. The germination records also showed an earliness of 20 and 22 days over the control and single-dose treatments respectively. 7. Treatments with 2 per cent, ammonium thiocyanate depressed germination. The respiratory rates recorded were also low. 8. In general the double-dose treatments showed better results than the single dose treatments. Also, treatments on 3 weeks old tubers were more effective than on 6 weeks old tubers.

US President Bush's fiscal 2003 budget proposal which was released on February 4 2002 clearly indicate where the Administrations priorities lie on issues of reproductive and sexual health. The main goals are the promotion of marriage regardless of circumstances and an insistence upon abstinence for all single people regardless of age. While the reauthorization of welfare reform is sure to continue to garner a great deal of attention for fiscal year 2003 advocates of reproductive and sexual health face a significant challenge. Moreover the Bush Administrations proposed spending on HIV/AIDS prevention care and treatment has done little to reassure advocates.


In this paper we study the modelling of consensus reaching in a 'soft' environment, i.e. when the individual testimonies are expressed as fuzzy preference relations. Here consensus is meant as the degree to which most of the experts agree on the preferences associated to the most relevant alternatives. First of all we derive a degree of dissensus based on linguistic quantifiers and then we introduce a form of network dynamics in which the quantifiers are represented by scaling functions. Next, assuming that the decision makers can express their preferences in a more flexible way, i.e. by means of triangular fuzzy numbers, we describe the iterative process of opinion changing towards consensus via the gradient dynamics of a cost function expressed as a linear combination of a dissensus cost function and an inertial cost function. Finally, some computer simulations are carried out together with a short description of a case study in progress.


The so-called "end of the world" – scheduled for the winter solstice of 2012 by certain groups of people – is moving rapidly into public focus. The topic receives ever more publicity in the media; Hollywood has even jumped in with Roland Emmerich's disaster film "2012". There is a burgeoning fascination with this event in the literature and on the internet – most of it arising outside the scientifically-based field of pre-Columbian studies, instead approaching the topic from an esoteric or New Age point of view. In 2006, Robert Sitler examined the esoteric side of the "2012 Phenomenon" and its (pseudo)-religious impact (Sitler 2006), so we will not put further attention on this aspect of the date. But since it is inevitable that our conclusions will find their way into the apocalyptic current, we hope they will not be excessively misconstrued. Apart from the influential prophecies for the K'atun 4 Ajaw in the Chilam Balam of Tizimín (MS pp. 19-20, Edmonson 1982: 168-171) and other sources, the main and most cited source for this "millennial current" (Sitler 2006: 33) in the popular perception is the right panel of Tortuguero Monument 6 (Gronemeyer 2006: 157-161, pl. 12, Figure 1). Several scholars have previously contributed to our understanding of the inscriptions of TRT Mon. 6 (Riese 1978, 1980: 10-16, Arellano Hernández 2006: 100-111), including specific focus on the phrase involving the Bak'tun ending of 220.127.116.11.0 (Eberl & Prager 2005: 32, Gronemeyer 2006: 45, Arellano Hernández 2006: 107, fig. 55,


Three new approximate methods for dynamic reliability calculation of stochastic structures are compared.A new technique named asymptotic expansions is based on Laplace's method for approximation of integrals.When the local maxima of the integrand are calculated,the failure probability can be derived from a simple analytical formula of asymptotic approximation.Since the main contribution to the integral comes from the domain in the neighborhood of the point of local maximum used in the asymptotic method,it is reasonable to assume that the most probable value of the important sampling density function equals to the local maximum.The third method employs the extreme value distribution to present the formula of failure probability of uncertain structures.Then an estimate of the failure probability is obtained based on Taylor series expansion.The central difference scheme is used to estimate the gradients of extreme value distribution.Finally,the failure probability of a single-degree-of-freedom random structure subjected to Gaussian noise excitation is calculated by using the above three methods and Monte Carlo method.Results show that the three methods are simple for calculation and are more efficient than Monte Carlo method.


Real life problems particularly in sciences and engineering can be expressed in differential
equations in order to analyse and understand the physical phenomena. These differential equations involve rates of change of one or more independent variables. Initial value problems of higher order ordinary differential equations are conventionally
solved by first converting them into their equivalent systems of first order ordinary
differential equations. Appropriate existing numerical methods will then be employed to solve the resulting equations. However, this approach will enlarge the number of equations. Consequently, the computational complexity will increase and thus may jeopardise the accuracy of the solution. In order to overcome these setbacks, direct methods were employed. Nevertheless, most of these methods approximate numerical solutions at one point at a time. Therefore, block methods were then introduced with the aim of approximating numerical solutions at many points simultaneously. Subsequently,
hybrid block methods were introduced to overcome the zero-stability barrier occurred in the block methods. However, the existing one step hybrid block methods only focus on the specific off-step point(s). Hence, this study proposed new one step
hybrid block methods with generalised off-step point(s) for solving higher order ordinary
differential equations. In developing these methods, a power series was used as an approximate solution to the problems of ordinary differential equations of order g. The power series was interpolated at g points while its highest derivative was collocated at all points in the selected interval. The properties of the new methods such as order, error constant, zero-stability, consistency, convergence and region of absolute stability were also investigated. Several initial value problems of higher order ordinary
differential equations were then solved using the new developed methods. The numerical results revealed that the new methods produced more accurate solutions than the existing methods when solving the same problems. Hence, the new methods are viable alternatives for solving initial value problems of higher order ordinary differential
equations directly.


This paper discusses the reasons for changes of electric energy intensity in Beijing by using the complete factor decomposition model. Researches show that the increase of electric energy efficiency promotes the decrease of electric energy intensity in Beijing during 1998—2007. Structure change has less effect on electric energy intensity. But the low utility level of electric energy in secondary industry and tertiary industry are the main reasons for changes of electric energy intensity in Beijing. Therefore, increasing the proportion of electric energy consumption in secondary industry and improving the electric energy efficiency of tertiary industry are effective ways to decrease electric energy intensity and advance electric energy utility efficiency in Beijing.

Clonal evolution of malignancy is a complex process related to intratumoral heterogeneity, as recent studies have also demonstrated in rhabdomyosarcoma. The purpose of this study is to present a distinct clonal feature of a case with anaplastic embryonal type rhabdomyosarcoma (ERMS) using molecular analysis.


This recital was prepared in collaboration with Dr. Polina Khatsko, Brent Mead, Nathaniel Welshons, and Tom Rauch. It was presented in partial fulfillment of the requirements for the University of Northern Iowa's Master of Music degree. The works presented were carefully chosen to showcase the performer's instrumental proficiency and understanding of a variety of solo tenor and alto trombone literature and chamber music. They are, in order, Concerto for Alto Trombone and Piano by Georg Christoph Wagenseil, selections from Dichterliebe by Robert Schumann, Improvisation No. 1 by Enrique Crespo, Fantasy for Trombone by Sigismond Stojowski, Concerto for Trombone and Orchestra by Launy Grøndahl, and Posaunenquartett by Frigyes Hidas. Georg Christoph Wagenseil, Concerto for Alto Trombone and Piano Georg Christoph Wagenseil was born in Vienna in 1715.1 He made a living as a composer, keyboardist, and teacher. His father worked as a functionary in the Viennese imperial court.2 Wagenseil was appointed to the court as a composer in 1739 and served until his death in 1777.3 He was celebrated as a renowned keyboard virtuoso and pivotal figure of Classical style in Vienna.4 The Concerto for Alto Trombone was written in 1763 for an unknown trombonist in Vienna.5 According 1 Kucaba, John and van Boer, Bertil H, "Wagenseil, Georg Christoph," Grove Music Online, Oxford Music Online, Oxford University Press, http://www.oxfordmusiconline.com/subscriber/article/grove/music/29767, Accessed October 15, 2016. 2 Kucaba and van Boer, "Wagenseil, Georg Christoph." 3 Ibid. 4 Ibid. 5 Oliver, Jason L, "The Creation of a Performance Edition of the Georg Christoph Wagenseil Concerto for Trombone With Attention Given to the Surviving Manuscripts and Primary Sources of Performance Practice from the Middle of the Eighteenth Century," DMA diss., (University of North Texas, 2010), 8.
