Friction and wear behaviour of different concentrations of hex‐boron nitride (h‐BN) nanoparticles in engine oil of grade SAE 20W50 were studied at various loads. These tribological studies were conducted using a four‐ball wear test machine and a pin‐on‐disc universal tribometer. Anti‐wear properties of SAE 20W50 + h‐BN were studied on the four‐ball wear test machine as per ASTM D4172 standard. Friction and wear properties of SAE 20W50 + h‐BN on piston ring and cylinder liner tribo‐pair were studied using the universal tribometer. Nanoparticles of h‐BN mixed in lubricant showed excellent tribological performance. In most of the cases, h‐BN nanoparticles as additive reduced the wear loss by 30–70% at various loads. The minimum value of coefficient of friction (0.0401) was found with SAE 20W50 + 3 wt% of h‐BN at normal load of 100 N. Scanning electron microscopy and Raman spectroscopy were used for characterisation of h‐BN and wear scars. Copyright © 2016 John Wiley & Sons, Ltd.


Abstract Corn silage-based diets containing 20, 40, or 60% (DM basis) corn gluten feed were fed to 72 lactating cows to determine intake, milk yield, and milk composition. These diets plus a control (no corn gluten feed) were fed to four ruminally fistulated cows to determine digestibility and ruminal ammonia and VFA concentrations. Milk yields were significantly lower for cows fed the diet with 60% corn gluten feed, but when adjusted by covariate, milk yield was not different among diets. Milk protein percentage was greater for cows fed the 40 and 60% corn gluten feed diets. In the digestion trial, increased corn gluten feed led to decreased DM digestibility and decreased ruminal acetate concentration but did not affect N, NDF, ADF, or starch digestibilities. Ruminal ammonia and pH were unaffected. Net energy estimates for the diets were low relative to book values, suggesting significant depression in digestibility. Compared with conventional diets, NDF intake was high; this suggests that cows compensated for lower digestibility with increased DM intake. Diets containing up to 60% of DM as dry corn gluten feed were acceptable for dairy cows.


Why is it, when faced with the decision to accelerate frustrated, bored, struggling gifted children, that the opinions we listen to the most come from uninformed, yet well-meaning family, friends, and even school personnel? It's time to listen to the real experts—the volumes of research conducted over the last 50 years by the most learned in our field and the families who have done it. In a recent survey, 22 parents, representing 26 children who were offered acceleration as an option, shared their experiences. All but two of the families jumped at the chance to accelerate. Even so, none of the families made the decision without a great deal of soul-searching. Most had to initiate the discussion themselves and bring forth the volumes of literature that supports acceleration as a positive move, before administrators would even consider it. The very people who should know and understand—teachers, administrators, and school psychologists—often are the least supportive.


Objective To observe the correlation between the changes of neural cell apoptosis arid caspase-3 gene expression in brain tissues following acute severe traumatic injury to brain(TIB).Method A total of 120 adult Spraque-Dawley rats were divided into a control group(n=8),TIB group(n=56)and TIB with administration of caspase-3 inhibitor group(n=56).TIB models of rats were made with Feeney's method.The z-DEVDfmk(5 μg),caspase-3 inhibitor,was administered by intracerebral infusion,and the rats were sacrificed 1,6,24,48 hours and 3,7,14 days postinjury(n=8 for each interval).The specimens of the injured cerebral cortex,suhcerticai white matter,hippocampus,dentate gyrus and contrahteral corresponding brain tissues were taken for detecting apoptesis of neural cells by the terminal deoxynucleotidyl transferase mediated DUTP nick end labeling (TUNEL)methods and flow cytomeay.Caspase-3 mRNA and protein expression were detected by using RT-PCR,immunohistochemistry and western blot analysis.The caspase-3 activity was detected by using caspase-3 fluorescent assay kit.Student t-test and Spearman correlation analysis were used to analyze the data with SPSS version 10.1 software package.Results Apoptesis indexes(AI)and the apoptesis percentage(AP)of neural cells in the injured brain regions increased quickly after injury,and reached its peak 24 to 48 hours later,then decreased slowly,but it remained at higher level above that of normal till 14 days later(P<0.01).The levels of caspase-3 mRNA,eastme-3 protein and caspase-3 activity were increased significantly post injury,and reached its peak at 24 to 48 hours,then it gradually decreased.Compared with control group,the levels ofoptical density of caspase-3 proteins in the injured hippocampus and subcortical white matter at 24 and 48 hours post injury increased 1484% and 1690%,caspase-3 mRNA expressiom increased 1043%and 1180%,and the degreas of caspase-3 activity increased 148% and 183%,respectively.The expression of caspase-3 proenzyme and its P17 subarrit increased.After trealment with caspase-3 inhibitor z-DEVD-fmk,the levels of caspase-3 mRNA,protein expression and caspase-3 activity were significantly decreased.and AI and AP were significantly decreased as well.The correlation between caspase-3 mRNA and level of neural apoptesis was positive(r=0.821,P<0.01),and it was likewise betweencaspase-3 protein and level of neural apoptosis(r=0.638.P<0.01).Interestingly enough,a positive correlation was found between caspase-3 mRNA and easpase-3 proteins(r=0.945,P<0.01).Conclusions The activation of caspase-3 leads to apoptosis of neural cells after acute TIB.The expression of caspase-3 are consistent with apoptosis of neural cells following TIB.The regulation of caspase-3 induced by TIB occurs at a ceriain critical link before transduction.Caspase-3 inhibitor can efficiently inhibit apoptosis of neural cells following TIB.

Abstract THE harmful effects of yolk and similar lipid material on the functional properties of egg white, long recognized, have been reviewed by several workers (Cotterill and Funk, 1963; Cunningham, 1963; Cunningham and Cotterill, 1964). The mechanism, however, whereby yolk is detrimental is not understood. Cotterill et al. (1963) showed that although the use of chemical additives inproved performance of yolk-contaminated egg white, additive actions were not solely associated with overcoming the adverse effects of the yolk. Cotterill and Funk (1963) found that lipase treatment improved yolk-contaminated white but did not determine if the improvement resulted from destruction of harmful yolk components or from products produced by hydrolysis (such as fatty acids). That pH is significant to functional performance, particularly for yolk-contaminated white, has been shown by Cotterill and Funk (1963) and Cunningham (1963). Cunningham and Cotterill (1964) found that centrifuging yolk-contaminated egg white improved its performance and that centrifuging at…

Abstract The aim of the study was to investigate experimentally the effects of restricted or ad libitum feeding in the far-off period on performance of dairy cows. Two groups of Polish Holstein-Friesian cows having 19 animals in each group were allotted to two planes of nutrition in the far-off period from -56 to -22 days. The ADLIB group was fed ad libitum (DMI 12.9 kg) while in the RES group the dry matter intake was restricted by 3 kg DM compared to the average dry matter during the last 7 days in the ADLIB group. Average daily energy intake decreased from 8.90 UFL in the ADLIB to 6.83 UFL in the RES group. In the close-up period and after parturition, the cows of both groups were given the same diet. In restrictively fed cows, there was a tendency to a greater decrease in BCS during both the dry period (P=0.09) and lactation (P=0.07). After parturition milk production, fertility indices and blood concentration of IGF-1, insulin and glucose were not significantly affected by the far-off treatment. In the RES group, lower BHBA 3 days before calving and on day 5 of lactation and lower NEFA on day 28 of lactation were recorded. Also in this group higher levels of glucose 3 days before calving, triiodothyronine (T3) on days -30 and 5, and thyroxine (T4) on days -3 and 28 were observed. It is concluded that restricted feeding in the far-off period positively affected blood indicators of lipomobilization during the transition period, but had little effect on performance of lactating cows. In spite of low energy, high-fibre diet offered ad libitum in the faroff period resulted in the energy overfeeding compared to the INRA system recommendation.

A fully integrated system-on-a-chip (SOC) in 130-nm CMOS technology compliant with world-band 802.11a/b/g is presented. This SOC integrates all blocks including 2.4-GHz/5-GHz RF tranceiver, baseband physical layer (PHY), and the medium access controller (MAC). At 1.8 V, the whole SOC dissipates 144/168 mA in receiving mode and 114/150 mA in transmitting mode for 2.4-GHz/5-GHz-band operations. The measured receiver sensitivity at 2.4 GHz/5 GHz is -77.5/-74 dBm at 54 Mb/s rate, and the transmitter EVM at 54 Mb/s rate is -33/-30 dB at an output power of -7/-8 dBm. By integrating multiple on-chip LDOs with no off-chip capacitors, this SOC features the capability of being directly supplied by off-chip switching-type DC/DC converter without performance degradation.


In this study, the thermo-mechanical behavior and microstructural transformations of AA2024 during the friction surfacing process have been investigated. A three-dimensional finite element model has been developed to predict the thermo-mechanical responses of materials during friction surfacing using the ABAQUS software. Then, the mechanical properties and microstructures of the coating layer were evaluated. The results show that the temperature of the advancing side of the coating increases more than that of the retreating side, which is consistent with the coating's tendency to deviate towards this side. The strain rate is also higher and more extended on the advancing side, which is the main reason for weaker coating bonds in this area than on the retreating side. The strain rate and maximum temperature in the coating layer increase with increasing the consumable rod rotational speed and the axial feeding rate, but an increase in the traverse speed increases the strain rate and reduces the maximum temperature. Although the material transfer process is asymmetrical, there are not any significant differences observed in the material microstructure and properties on the advancing and retreating sides. The cooling rate appears to be the most effective factor on the coating grain size at the coating/substrate interface. Higher cooling rates results in the formation of finer grains at the interface. It can be noted that the effect of strain energy stored in the coating layer during friction surfacing on the grain structure evolution and the interface bonding strength is negligible. Therefore, heat flow was found out to be the prominent factor in the coating grain size and strength.


A neogranadino reminded readers of the Correo del Orinoco (delivery 61, 1820) that of the 22 provinces in 1810 constituted the jurisdiction of the Viceroyalty of New Granada (including three of the Audience of Quito), only eleven had integrated the Congress of the United Provinces of New Granada during its short existence: Cartagena, Popayan, Antioquia, Choco, Tunja, Neiva and Pamplona, which were the constituents; Socorro, which was integrated as separated from the domain of Cundinamarca, and those integrated by force of arms: Santa Fe, Mariquita and Los Llanos, when troops of the Congress headed by Colonel from Caracas entered to the capital. This means that despite the reunion of Cundinamarca and the Congress, half the provinces have become strongholds of the Regency Council and one of them, Panama, the new headquarters of the Viceroy and the Royal Audience. That is why this paper presents a overview of the different behavior of the 19 provinces of the Royal Audience of Santa Fe during the time of the crisis of the monarchy of the Spains, trying to draw attention to the fact that the conduct of the province of Santa Fe was not the only paradigm of what happened in the New Kingdom of Granada.

Background : ozone therapy has been successfully used in the treatment of pulpitis, periodontitis, aphtha, ulcers, denture-related stomatitis, infected root canals, as well as in the disinfection of cavities during surgery and postoperative care, just to mention some examples. Objective : to assess the effectiveness of Oleozon in the treatment of recurrent aphthous stomatitis, in patients older than 12 years of age who visited the emergency department of dentistry of the "Guillermo Tejas Silva" Teaching Policlinic, from February to December 2017. Methods : a therapeutic intervention was carried out in a sample of 32 patients with the characteristics declared in the objective, at the place and during the period herein mentioned. The sample was randomly distributed in two groups: the control group with a conventional treatment and the study group that underwent treatment with Oleozon. Both groups received the indications of not taking vitamins E and C during the treatment period. The patients were assessed on the third, fifth and seventh days. Results : there was a higher presence of the female sex (62,5 %). According to the affected anatomic region, in both groups the lesions on the labial mucosa and on the alveolar mucosa prevailed. On the third day of treatment half of the study group had progressed favorably, and only 12,5 % of the control group. At the end, 93,7 % of the study group and 68,7 % of the control group were healed. No adverse reactions related to the treatment were reported. Conclusions : ozone therapy was effective for the treatment of recurrent aphthous stomatitis in the studied sample of patients.


Well before Dr. Minkowski discovered the role of the pancreas in regulating blood glucose (1889), Dr. Bernard had discovered the role of the brain (specifically the base of the fourth ventricle) in regulating blood glucose (1849). Bernard's basic observation has been replicated by many interventions involving pharmacological manipulations directed toward the brain stem (1). Nevertheless, the overt production of diabetes by the removal of the pancreas and the eventual discovery of the determinative role of insulin secreted by pancreatic islets in regulating blood glucose by Drs. Banting and Best (1922) led to an overwhelming emphasis in studying islet function (and later insulin sensitivity) in the study of blood glucose regulation.

At about the same time, the function of the hypothalamus began to be studied extensively because of early evidence that damage to the hypothalamus in humans produced a variety of neuroendocrine disturbances, including obesity (Erdheim 1904). However the relative importance of the hypothalamus versus the pituitary in these systemic pathologies continued to be controversial until the classic study by Hetherington and Ransom (2) reported that specific lesions in the ventromedial nucleus (VMN) cause robust obesity in rats, an extremely robust effect replicated in many species, including humans. Subsequent extensions of these studies demonstrated that lesions of an area slightly lateral to the VMN (lateral hypothalamic area [LHA]) produced the opposite effect: starvation. …


Satellite communication is high-speed large-capacity transmission intended to communicate with satellites in the chamber. It is wide-area communication, but the information is not secured. To compensate for this, AES encryption was applied to the CTR and CBC modes. Input data were compared by applying encryption to two types of data: voice and video. Simulation results were determined using SNR, BER, and PER, with conclusions from graphic analysis. In the case of voice data, performance indicators were 'adding Rfactor' and MOS. In the case of video data, the performance indicators were adding RMSE and PSNR. Key-Word : Satellite communication, AES encryption, CTR mode, CBC mode, Voice, Video, SNR


Synovex® ONE is an extended‐release implant containing the active ingredients estradiol benzoate and trenbolone acetate for use in beef steers and heifers. Trenbolone acetate is rapidly hydrolyzed in cattle to form 17β‐trenbolone and its isomer, 17α‐trenbolone, which are further transformed to a secondary metabolite, trendione. As part of the environmental assessment for the use of Synovex ONE, data were generated to characterize the fate of 17α‐trenbolone, which is the principal metabolite found in cattle excreta, in the environment. A study was conducted to determine the degradation and transformation of [14C]‐17α‐trenbolone in 2 representative water–sediment systems under aerobic conditions. The same transformation products, 17β‐trenbolone and trendione, were formed, principally in the sediment phase, in both systems. From the production of these transformation products, the 50% disappearance time (DT50) values of 17β‐trenbolone and trendione were determined, along with the DT50 values of the parent compound and the total drug (17α‐trenbolone + 17β‐trenbolone + trendione). The DT50 values for the total system (aqueous and sediment phase) and for the total residues (17α‐trenbolone + 17β‐trenbolone + trendione) in the 2 systems were 34.7 d and 53.3 d, respectively.

Abstract In this paper, two-component mixtures (spironolactone with hydrochlorothiazide, captopril with hydrochlorothiazide, and spironolactone with furosemide) were assayed by U.V. (A), first derivative (dA/dlD) and second derivative (d2A/dlD2) spectrophotometric methods, applying "Zero-Crossing" technique of measurement. The methods were proved using laboratory prepared mixtures. The utility of the methods in assay of dosage forms is also presented.


As LANs/MANs operate at higher speeds (100 Mb/s-Gb/s) and over longer distances (10's - 100's km) the access mechanism has to be chosen carefully so as to provide high utilization. Protocols are available that operate efficiently at high speeds and long distances. We describe here a particularly simple access mechanism referred to as Simple (S). Performance is simulated under a range of traffic, physical lengths, number of stations and overload conditions. S is compared with both Fasnet and the Distributed Queue Dual Bus (DQDB) schemes. It is almost as efficient as more complex protocols and its overload performance is well behaved.


English-language advertising discourse today is undergoing significant improvement and changes. This is due to the transition to online modes, where a person's personality is manifested through the criteria of affection, awareness and attractiveness. However, the negotiation system of a separate feature of the English-language (appearance, manner, knowledge and application of business etiquette) discourse is subject to improvement and practice. If before the transition to the online mode, the tools, means and methods of English-language advertising discourse were worked out, then with the transition to the digital dimension, they require clarification, explanation, adaptation, excluding audio technical transmission channels. The purpose of the study is to outline the main directions in which the developed tools of the English-language advertising discourse are transformed. The methodology was statistical research, which analyzed the appearance of a person in English-language advertising discourses, taking into account forms and types. An approach was also used in which a comparison of a person's appearance was made, taking into account the advertising slogans of foreign companies, as well as various segments in which the analyzed companies operate. As a result of the study, a significant influence of English-language constructions and techniques was noted in comparison with various external images of a person. A theoretical mechanism for the formation of modern English-language advertising discourse is proposed. In general, a list of priority effective means and forms in the formation of modern English-language advertising discourse has been revealed.

The electric dipole transitions between states of the intervalley donor multiplet in Ge-type semiconductors placed in an external constant electric field are considered. The assumption that a short range component of the impurity potential plays a dominant role is used in the calculations. For transitions of different types expressions for the oscillator strengths, describing their field and angle dependences, are derived.

Laser microfabrication allows high precision ablation of materials at sub-mm scale. When laser pulse length is shorter than about 10 picoseconds the heat affected zone is minimized and ablation occurs without melting. Workpieces processed in this fashion exhibit less structural damage and are expected to have a higher damage thresholds. In this paper we will review several case studies of lasermicrofabricated components for accelerator and x-ray applications. Ablated materials include diamond, quartz, tungsten, copper, YAG:Ce and silicon.


In wireless sensor networks, it is a typical threat to source privacy that an attacker performs backtracing strategy to locate source nodes by analyzing transmission paths. With the popularity of the Internet of Things in recent years, source privacy protection has attracted a lot of attentions. In order to mitigate this threat, many proposals show their merits. However, they fail to get the tradeoff between multi-path transmission and transmission cost. In this paper, we propose a constrained random routing mechanism, which can constantly change routing next-hop instead of a relative fixed route so that attackers cannot analyze routing and trace back to source nodes. First, we design a specific selection domain which is located around the sending node according to the dangerous distance and the wireless communication range. Then sending nodes calculate the selected weights of the candidate nodes according to their offset angles in this domain. Finally, the selected weights help to decide which node will become the next hop. In this way, attackers would be confused by the constantly changing paths. The simulation results prove that our proposal can achieve high routing efficiency in multi-path transmission, while only introducing a controllable energy consumption, end-to-end delay and redundant paths.


Today, many cities around the globe are interested in developing or adopting smart city policy frameworks; however, the complexity of the smart city concept combined with complicated urban issues makes it a highly challenging task. Moreover, there are limited studies to consolidate our understanding of smart city policymaking. The aim of this study was to bridge this knowledge gap by placing a set of official smart city policy frameworks under the policy analysis microscope. The study approached the analysis by, firstly, internationally collating the smart city policy frameworks of 52 local governments from 17 countries. The methodology then progressed to a deductive content analysis of the identified policies with a thematic data analysis software. The investigation employed the main themes to identify common urban issues in smart city policies—i.e., smart economy, smart environment, smart governance, smart living, smart mobility, and smart people. The results revealed the targeted key planning issues, goals, and priorities, and the ways that smart city policies address these key planning issues, goals, and priorities. The study findings inform policymakers, planners and practitioners on the smart city policy priorities and provide insights for smart city policymaking.


QoS provisioning to users in the presence of volatility of the wireless channel is the most challenging issue in wireless system design. We consider the problem of scheduling constant bit rate (CBR) traffic packets over the wireless channel, subject to packet delivery deadline constraints. We cast the problem as a Markov decision process and derive the optimal scheduling policy, in the sense of minimizing long-term packet loss due to deadline expirations. Performance bounds and design guidelines for general scheduling algorithms are obtained through analysis and simulations.


The debate about industrial relations developments in Europe in recent years has focused on the multiple impact of the crisis ( nancial, economic and scal) and of policy and regulatory reforms promoted by European economic governance, the socalled Troika, and national governments (Marginson 2014; Marginson and Welz 2014; Papadakis and Ghellab 2014; Schulten and Müller 2015; Koukiadaki et al. 2016; Guardiancich and Molina 2017). Against this background, the di erent developments that have characterised national industrial relations systems entail a number of tasks, not only at the academic level, but also at the operational or practical level. First of all, it is important to improve our knowledge of the di erent national trajectories and analyse evidence in a comparative perspective. There is remarkable potential here for cross-national fertilisation and strategic learning; these are key components of both scholarship and social partner initiatives in labour relations. Secondly, such knowledge and analyses can contribute to strengthen forms and tools of cooperation and coordination at European level, which trade unions at both national and European level have been promoting for many years.


A 56-year-old woman presented with acute, painful, flaccid quadriparesis, which started proximally in the lower limbs and reached nadir over 1 week. She had a power of modified research council grade 1/5 in the upper and lower limbs, neck muscle weakness, graded pan-sensory loss till knees, generalized areflexia, and digital clubbing. The nerve conduction study revealed an axonal pattern, whereas cerebrospinal fluid revealed 10 cells (lymphocytic), raised protein level (72 mg/dL), and normal glucose level. She was diagnosed with Guillain-Barré syndrome and treated with intravenous immunoglobulin, without improvement. Eight weeks into illness, she developed intermittent, severe, left hypochondriac pain, incompletely relieved with parenteral analgesics. Computed tomography of the abdomen and upper gastrointestinal endoscopy were normal. She had a history of alternative medication intake. The toxicology screen revealed high serum lead levels (48 μg/dL, upper limit 25 μg/dL). She was advised to stop alternativemedications andwas given symptomatic treatment. However, she went on to develop sudden-onset dysarthria and right upper motor neuron facial palsy. Magnetic resonance imaging of the brain revealed multiple acute infarcts (Figure). Magnetic resonance angiography was normal. We revisited the diagnostic possibilities. Repeat investigations revealed frank proteinuria (1200 mg/d), elevated erythrocyte sedimentation rate and CRP levels, and p-ANCA positivity (p-ANCA: anti-MPO levels, >100 U/mL; reference, <9U/mL).Urine for porphobilinogen, viralmarkers, and serum electrophoresis were negative. The patient refused a nerve biopsy.


Results of a study of radiation effects on electronic materials, devices, and integrated circuits are presented in this report. Emphasis was placed on determining the underlying mechanisms responsible for observed radiation effects with a view toward gaining an understanding of the value in the development of radiation-hardened devices. Measurements and analyses were performed on the effects of single energetic neutrons and protons on silicon integrated circuits. In addition, a detailed description is given of the effects of radiation-induced displacement damage on device depletion regions. Single-event upset studies included charge-collection and transient-current measurements on Si and GaAs devices following a single alpha-particle strike. The angular dependence of charge funneling was also investigated. The mechanisms of ionizing radiation effects on Si MOS devices were explored in detail using the thermally stimulated current technique and other measurement approaches. Data obtained by several techniques show that use of the radiation-induced shift of the capacitance-voltage curve at midgap is not generally valid for determining oxide trapped charge.

Preservation and management of the genetic resources of Arabica coffee (Coffea arabica L): A challenge for Ethiopia The montane rainforests in the south-western part of the Ethiopian Plateau are the natural habitat and primary centre of diversity of Coffea arabica L. Although deforestation is a long-lasting phenomenon, it recently amplified mainly due to growth in the population of the country and the application of governmental policies that conflict with the customary rights of local communities. After a brief history and presentation of the current state of ex situ conservation of Ethiopian coffee genetic resources, we enlarge on the concepts recently developed by research and extension projects involved in the in situ conservation of forest and garden coffee (biosphere reserves, participatory forest management, coffee certification, and geographic indications). Those projects aim at reconciling the objectives of conservation of biodiversity, economic development, and preservation of the local cultures and know-how.


Many traditional societies have extensive natural pharmacopoeia, largely from the plant resources found in natural environments occupied by these populations. The plants are like the identity of a group of people, reflects what they are, what they think and their relationship with nature that surrounds them, so the use of plants for therapeutic purposes is part of a social and ecological context of thus many of the peculiarities of this job can only be understood if this context is understood. The main advantage of the natural product or medicinal plant is little side effect it will have on the individual's body, given that this therapy does not leave the same amount of bioactive or chemical residues within those who use them. In Brazil, there is a vast medicinal flora, many plants are still unknown to the scientific, but others are used daily, this consumption is called herbal medicine and its practice is becoming a global trend. From this perspective, this study aims to identify the medicinal plants known by the students of high school at the State Elementary School and Middle Argemiro de Figueiredo Multipurpose, evaluating the use of the product in question and the relationship that makes use of context social student. With this, we can, in the future, assess in other contexts as municipal and / or state. It is known that public spending on health can affect the search community to manufactured drugs, these, in turn, become increasingly inaccessible poor populations, thus it is necessary the knowledge of medicinal plants and it is very important to educate the children for them to pass this information to the front. In the current study, conducted through a questionnaire, found that students medicate through herbal medicine much less than expected, but the vast majority who uses this device states that obtained their knowledge through an older relative. In this sense, it is confirmed the need for increased support to the knowledge of the use of medicinal plants. Tags: relationships with nature. Herbal Medicine. high school students.


A typical transoceanic submarine cable route survey includes a vast amount of information spanning thousands of kilometers, with additional data types and increased resolution near continental margins. Formerly, cable installers have requested paper charts. This information is static, and changes to routing can result in increased costs and lost data. In addition, retrieving the charts for later maintenance purposes is awkward. We submit that submarine cable survey data would be more useful if organized into a geographically-referenced database. This GIS database would include route-planning information and all survey data. We present an example of a GIS database created for a recent survey.


In this paper, we propose a novel approach to reduce spatial query access latency and energy consumption by leveraging results from nearby peers in wireless broadcast environments. We propose a three-tier Hierarchical Location-Based Sequential access index, called HLBS, which provides selective tuning (pruning and searching entries) without pointers using a linear accessing structure based on the location of each data object. The HLBS saves search cost and index overhead, since the small index size with a sequential index structure results in low access latency overhead and facilitates efficient searches for sequential-access media (wireless channels with data broadcast). Comprehensive experiments illustrate that the proposed scheme is more efficient than the previous techniques in terms of energy consumption.


We analyze the behavior of common indices used in numeri- cal linear algebra, analysis, and optimization to measure rates of conver- gence of an algorithm. A simple consistent axiomatic structure is used to uniquely define convergence rate measures on the basic linear, super- linear, and sublinear scales in terms of standard comparison sequences. Agreement with previously utilized indices and related measures is discussed.


The effect of the disaster was more heavily felt in the micro-, small- and medium-establishments operating in the households of the affected areas. This finding implied a heavier burden on the household economy and therefore called for intervention in terms of livelihood and employment.


Wetland is an important eco-system on the earth and can effectively control agricultural non-point source pollution. Reed is a typical wetland plant for land/inland water ecotone in north China. The studies indicated that reed had a underground rooted-stem, which formed a "high speeded-connecting vessels" i.e. reed root channel (RRC) in Baiyangdian lake of Hebei province. It spread predominantly along horizontal direction underground and are mainly distributed at 18-75 cm. The results of field work from healthy reed-wetland (HRW) and regarded reedwetland (RRW) showed that the reed, averagely, in HRW is 4.2 m height, 1 cm diameter, 65/m2 density; in RRW is 2.4 m height, 3 mm diameter, 86/m2 density. These results indicated the regradation of the function of RRC in RRW. The results of laboratory work of sewage purification from reed soil column (RSC) (0~100 cm) and wheat soil column (WSC) showed that the efficiency of purification to sewage, in RSC, is high than in WSC, especially for phosphorus. The efficiency of purification, in RSC, is 92.6% for total phosphorus, 43.5% for total nitrogen, 54.1% for COD, respectively; in WSC, is 86.0% for total phosphorus, 241.3% for total nitrogen, 29.8 % for COD, respectively.

Land management in agricultural lands has important effects on soil organic carbon (SOC) dynamics. These effects are particularly relevant in the Mediterranean region, where soils are fragile and prone to erosion. Increasing interest of modelling to simulate SOC dynamics and the significance of soil erosion on SOC redistribution have been linked to the development of some recent models. In this study, the SPEROS‐C model was implemented in a 1.6‐ha cereal field for a 150‐year period covering 100 years of minimum tillage by animal traction, 35 years of conventional tillage followed by 15 years of reduced tillage by chisel to evaluate the effects of changes in land management on SOC stocks and lateral carbon fluxes in a Mediterranean agroecosystem. The spatial patterns of measured and simulated SOC stocks were in good agreement, and their spatial variability appeared to be closely linked to soil redistribution. Changes in the magnitude of lateral SOC fluxes differed between land management showing that during the conventional tillage period the carbon losses is slightly higher (0.06 g C m−2 yr−1) compared to the period of reduced till using chisel (0.04 g C m−2 yr−1).


The role of mitochondria in insulin resistance and type 2 diabetes (T2D) is the subject of much debate. Recent evidence has suggested the presence of altered skeletal muscle mitochondrial dynamics, both increased fission and reduced fusion, in the etiology of insulin resistance and T2D, however, it is unclear what role, if any, changes in mitochondrial dynamics play in the induction of insulin resistance. We have proposed that increased mitochondrial fission may represent an early mechanistic link between the mitochondria and the onset of skeletal muscle insulin resistance. To test this hypothesis we recruited healthy humans to receive, in a randomized crossover design, an overnight saline (control) or lipid infusion (20% Intralipid) at 0.55 ml/kg/h, followed by a 2h, 90 mg/dL, 40 mU/m2 hyperinsulinemic-euglycemic clamp to assess insulin sensitivity. Changes to mitochondrial dynamics protein expression were assessed by western blot, ex vivo mitochondrial membrane potential (TMRM staining) by confocal microscopy, oxidative capacity by respirometry (Oroboros O2k), and mitochondrial morphology by transmission electron microscopy, in skeletal muscle biopsy samples following the overnight infusions. Preliminary data (n=8; 5M, 3F; Age: 26±1 years; BMI: 22.6±0.7; VO2max: 44.0±2.5) indicate that lipid infusion results in a tendency for reduced insulin sensitivity (P=0.08) and mitochondrial membrane potential (P=0.09), and an increase in Complex I state 3 respiration (P Disclosure C.E.

Bronchopulmonary neuroendocrine tumors account for only 20% of all lung carcinomas. These tumors are separated into four subtypes of low-grade (typical carcinoids), intermediate-grade (atypical carcinoids) and high-grade carcinomas which include large cell neuroendocrine carcinoma (LCNEC) and small-cell lung carcinoma (SCLC). LCNEC is a rare entity of aggressive cancer with poor prognosis. LCNEC is typically seen in older male with significant smoking history. We are presenting a young man with only five pack year smoking history and cushingoid features who was found to have LCNEC.


The adsorption process depends on initial concentration of Cd 2+ and ratio of  chitosan in adsorbent. The present study deals with the competitive adsorption of Cd 2+ ion onto silica graft with chitosan. Batch adsorption experiments were performed at five different initial Cd 2+ concentrations (5, 10, 15, 20 and 25 ppm), on five different proportion from silica to chitosan (100%, 95%, 85%, 75% and 65%) as adsorbent at pH 5. In the recovery process, the high recovery at 0.5 mg and observed the recovery decrease with increasing the initial concentration of Cd 2+ , and the low recovery at 0.25 mg from Cd 2+ . In this study, the adsorption capacity of Cd 2+ in regard to the ratio of silica and chitosan hybrid adsorbents are examined in detail. The aim of this study to explore effects of initial concentrations of Cd 2+ , and the ratio of silica to chitosan on the adsorption and recovery of Cd 2+ .


The nylons functionalised with single walled carbon nanotubes (SWCNTs) at pH 2.5 and 3.5 display the time dependence of the water droplet contact angle, which is attributed to the adsorption of water molecules onto the nylon–water contact surface and the consequent increase in surface free energy. The contact angle of nylons functionalised at pH 4.5, 6.5 and 8.0 varies marginally with contact time, presumably owing to the presence of a large amount of SWCNTs on the nylon surface. Using the obtained nylon as a flexible electrode, an electrowetting on a dielectric system is designed. The contact angle decreases with the increase of the applied voltage and the electrowetting response is sensitive to the surface free energy of the water droplet. A low surface free energy is preferable for actuating the movement of the water droplet at a low-driving voltage.


Thirty-four cases of verapamil-Cardioplegic solution perfused cardiopulmonary bypass were observed serially. 6hearts(17.6%)difibrillated at 10~38 minutes after aortic unclamping. There were no significant relations of verapamil-related factors such as serum calcium level, but significant of verapamil-unrelated factors such as age, heart ischemic interval and global heart tension between delayed and un-delayed difirillated sub-groups. Postoperative cardiac performance and myocardial ultrastructure were well protected in the delayed subgroup. Authors suggest and the indication of the administration of verapamil-cardioplegic solution and the tratment for seriously delayed diffibrilation.

In this tutorial we will discuss three layers of VMware software stack that work together to create a cloud environment. These layers include ESX hypervisor, VirtualCenter (vCenter) for management and vCloud Director to combine various virtual centers in to a scalable cloud environment. I will describe each one of these in more detail, while focusing on resource management controls that are provided at each layer. First, I will present the high level architecture of ESX and resource management model that is available for better performance isolation among VMs and high consolidation. ESX provides a very rich set of controls for all resources including CPU, memory, network and storage IO. The next step in resource management is providing techniques to handle a group or cluster of hosts. VMware technologies such as DRS can take care of automatically placing VMs on a cluster and performing load balancing across hosts using live migration of VMs (a.k.a. vMotion). Similarly a recent feature called Storage DRS provides initial placement of virtual disks on a cluster of storage devices and does load balancing across storage devices using live virtual disk migration. I will conclude with our cloud product called vCloud Director, which allows federation of multiple vCenters.


Aims: Pain due to the removal of the chest tube is one of the important complications after open heart surgery. In the case of inadequate pain management, sympathetic system is stimulated and can lead to irreversible complications. Studies showed the effect of reflexology massage on pain relief in other cases; so this study had been done with the aim of "determining the effect of foot reflexology on the pain of the patients under open heart surgery during chest tube removal". Methods: This randomized clinical study with control group was done in the hospitals covered by Baqiyatallah Medical Sciences University in 2013. Ninety samples were divided into three experimental, control and placebo-treated groups based on randomized allocation. Pain level was measured through Numerical Rating Scale (NRS) in all the three groups before intervention. In the experimental group center of the anterior one-third and in the placebotreated group, Posterior one-third of the left foot was being massaged for ten minutes before chest tube removal. There was no measurement in the control group. After removal of the chest tube, the level of the pain was measured and documented immediately. Data were analyzed by SPSS18 software by the help of descriptive and inferential statistics. Results: Difference in the mean of the quantitative variables including; age, height, weight and level of the body and demographic qualitative variables of the patients including; education status, occupation and marital status was not significant (p>0.05). Expected increasing of the pain due to the chest pain tube removal was not significant in the experimental group (p=0.08), while placebo-treated and control groups had significant increase of the pain (p=0.001 and p=0.000


Romania Abstract. The spread of the Corona virus has brought about major changes in the world. Even before, this technology was an important presence in practically every sphere of our daily routine. There is a widespread assumption that the population existing in the rural areas is hesitant towards accustoming to modernization. This paper is an inquiry constructed on the base of a questionnaire designed to determine the standpoint of the parents having children enrolled at primary level school in relation to the compulsory new ICT tools at school and at home, the difficulties and their awareness of the array of possibilities offered by communication science. The research was conducted at the end of June 2021 and it focuses on the period from March to June (2019-2020 school year) when all schools in Romania were performing online classes. The pupils comprised in this respective case study attend "Oborani Elementary School (I - IV)", a rural school with pupils from the preparatory level to the fourth grade from Viș ina Village in Dâmbovița County, This study aimed at identifying the impact online schooling had on an average class group from a primary school from a rural area. Online schooling translates into the usage of only ICT tools in class to support teaching. It was carried on at Școala Oborani, a recently modernized institution (having primary classes I- IV) in Dâmboviț a concerning a class of 1 st graders. The number of subjects involved in the experiment is 40 parents of 20 children (aged from 7 to 8 years old) coming from mostly middle social class. The study compares the presence, the involvement and results the pupils had in the first foreign language studied at school (their 2-nd year) – in their case – English classes. The research aims to observe the educational process during the emergency state and to come up with ideas of improvement.


Centrifuge tests to investigate the behavior during initial reservoir filling of a concrete faced rockfill dam (CFRD) with face slab stiffnesses that vary by a factor of about two are described. The two centrifuge models exhibited similar deformations at the crest and along the face slab, with crest settlements averaging 0.19H (%) and maximum face slab deformations averaging 0.88H (%). The centrifuge test results suggest that the face slab stiffness had little effect on deformations, at least for the range of stiffnesses examined here. A parametric study of transition (supporting) zone stiffness was performed using a numerical model calibrated using the centrifuge results. The numerical results indicated that face slab deformation is more influenced by transition zone stiffness than face slab stiffness, supporting the centrifuge results. Deformation measurements for 25 in-service CFRDs (including six Korean CFRDs—one of which was used as the basis for the centrifuge model dam) are presented and compared w...


An experimental study of the effects of aft blowing on the forebody vortex asymmetry over a 3.0 caliber tangent ogive body at high angles of attack was conducted. The tip of the ogive body was equipped with a single blowing nozzle whose position could be adjusted. The tests were conducted in a subsonic wind tunnel at laminar flow conditions. The effects of model roll, angle of attack, blowing coefficient, and blowing nozzle axial position were independently studied. Surface pressure measurements and flow visualization results were obtained. Aft blowing was observed to alleviate the degree of vortex asymmetry at all angles of attack. The blowing was found to be more effective at the higher angles of attack. However, proportional control of the degree of vortex asymmetry was not observed, because the initial flowfield was highly asymmetric.

Spain has suffered a lot from the current crisis and is the first large economy that may find itself in need of fiscal rescue. If this happens it may prove quite damaging to the euro. Yet, since the mid-1990s, Spain was a champion of growth and fiscal stability; its unemployment had fallen rapidly to the levels that prevailed in the rest of the European Union. This chapter discusses the reasons why such a virtuous initial situation deteriorated so sharply since the start of the crisis. Was this just bad luck or were the booming years just a mirage?


A supplementary wind-tunnel investigation has been conducted to determine the effect of rearward positions of the center of gravity on the spin, longitudinal-trim, and tumbling characteristics of the 1/20-scale model of the Consolidated Vultee 7002 airplane equipped with the single vertical tail. A few tests were also made with dual vertical tails added to the model. The model was ballasted to represent, the airplane in its approximate design gross weight for two center-of-gravity positions, 3O and 35 percent of the mean aerodynamic chord. The original tests previously reported were for a center-of-gravity position of 24 percent of the mean aerodynamic chord.


Based on the qualitative analysis of the relationship between Huai'an regional logistics and regional economic growth, the paper defines the measures of regional logistics and regional economic development level. The Granger causality test model is used to describe the relationship between regional logistics and economic growth in Huai'an. The result shows that in the long term, the relationship between regional logistics and regional economic growth is consistent with the results of qualitative analysis. That is, Huai'an GDP increment is proportional to the logistic increment. Research can provide quantity basis for the synergy analysis of regional logistic and economic.


A crucial factor that has to be considered in the operation of the robot manipulators is optimal trajectory planningit has a main goal of generating path from initial to final points in the operation that minimizes the, path travelling distance, energy consumption and avoiding obstacles. As an infinite number of solution can exist to manipulate the operation from one point to other, an optimal time-trajectory must be created to attain high productivity for a particular operation. This paper proposes a hybrid optimization method, which incorporates Analytical Hierarchy Process (AHP) in Genetic Algorithm (GA) to optimize point to point trajectory planning for a manipulator to avoid collision with any obstacles in the robot workspace. The GA objective function aims to optimize the excessive driving force, joint travelling distance, trajectory length and consumed time; the objective function also considers an optimized value obtained from AHP as a weighing factor. The control attributes like travelling space, time and torque are considered in AHP to optimize. In joint space to define the segments that connect initial, intermediate and final point quadrinomial and quintic polynomials are used.


The phase equilibrium of fluorite Ca1−xLaxF2+x solid solutions in the CaF2 - LaF3 system is investigated by means of DTA and X-ray analysis. The phase diagram of his system is of eutectic type with limited solid solutions with the structure of components. The eutectic coordinates are 1311°C and 58 mole% of LaF3. The saturation line of fluorite solid solution has an anomalous S-shape. The elementary cell parameter of this solution has been approximated by the parabolic equation a = ao + 0.597x + + 0.134x2, where ao = 5.46295 A denotes the parameter of CaF2 elementary cell.

Both dc/from 20 to 450°C/and ac/from 450 to 600°C/electrical conductivities were measured at concentrations covering almost whole region of the Ca1−xLaxF2+x solid solution formation. They are characterized by increasing conductivity and decreasing activation energy with increasing LaF3 concentrations. In samples with x > 0, 11 an increase of electrical conductivity due to aging was observed.

Purpose: In order to improve the energy strategies for a building space, various control methods of supply air have been examined in aspects of its energy efficiency and users' thermal satisfaction. This simulation study examines the network-based learning model's capability to maintain the thermal comfort without compromising on its energy efficiency especially in a very hot and humid area. Method: A network-based learning controller is proposed to optimize the supply air conditions to meet desired values of set-point temperature and comfort levels by regulating the amount of air and its temperature elaborately. Result: In a comparison with two other types of controllers, the proposed model improves the thermal comfort by about 29.3% than the conventional thermostat controller, and increases the energy efficiency by about 17.2% than the fuzzy-based controller. It is concluded that the network-based learning algorithm properly works to manage its supply air condition to improve spatial thermal quality in a very hot and humid area.


We measure the absolute proper motion of Leo I using a WFPC2/HST data set that spans up to 10 yr to date the longest time baseline utilized for this satellite. The measurement relies on ∼2300 Leo I stars located near the center of light of the galaxy; the correction to absolute proper motion is based on 174 Gaia EDR3 stars and 10 galaxies. Having generated highly precise, relative proper motions for all Gaia EDR3 stars in our WFPC2 field of study, our correction to the absolute EDR3 system does not rely on these Gaia stars being Leo I members. This new determination also benefits from a recently improved astrometric calibration of WFPC2. The resulting proper-motion value, (μ α , μ δ ) = (−0.007 ± 0.035, − 0.119 ± 0.026) mas yr−1 is in agreement with recent, large-area, Gaia EDR3-based determinations. We discuss all the recent measurements of Leo I's proper motion and adopt a combined, multistudy average of (μα3meas,μδ3meas)=(−0.036±0.016,−0.130±0.010) mas yr−1. This value of absolute proper motion for Leo I indicates its orbital pole is well aligned with that of the vast polar structure, defined by the majority of the brightest dwarf spheroidal satellites of the Milky Way.


Newcastle disease is caused by Newcastle Disease Virus (NDV) leads to severe morbidity and mortality in poultry throughout the world and considered as lentogenic, mesogenic or velogenic based on the mean death of the chicken embryo. The NDV velogenic strain is deadly endemic in Pakistan. Poultry is considered as the second major industry in Pakistan having annual growth of 8-10%. Unfortunately, the increase of NDV cases leads to severe cost impact, loss of production and livelihood. This review highlights the current status and epidemiology of NDV in Pakistan. Various genotypes and sub-genotypes have been identified in Pakistan. Various ND cases have been reported in Pakistan which has very bad consequences on the economy and dealing of poultry products.

Many storage formats for sparse matrices have been developed. Majority of these formats can be parametrized, so the algorithm for finding optimal parameters is crucial. For overall efficiency, it is important to reduce the execution time of this preprocessing. In this paper, we propose a new algorithm for the determination of the number of nonzero blocks of the given size in a sparse matrix. The proposed algorithm requires relatively a small amount of auxiliary memory. Our approach is based on the Morton reordering and bitwise manipulations. We also present a parallel (multithreaded) version and evaluate its performance and space complexity.


Background of the study: To study the efficacy of "Strength Training" on gait parameters of spastic CP. Design: Informal experimental design (before and after no control group design). Setting: Child Development Centre, Valancheri, Kerala. Participants: Twenty six spastic cerebral palsy children with a mean age of 4.6 years, including nine male and eighteen females were studied for a total duration of eight months. All the children were selected following strict inclusion and exclusion criteria. The study group was a mix of children with crouching, hemiparesis and vertical knee stiffness. Following the baseline evaluation procedures, the children were treated with specially structured Strength Training under the NSCA guidelines. Post intervention data were collected at the end of four months of training. Outcome measures: Gait speed, one minute walk test, timed up and go test, thirty seconds sit to stand test, ten meter walk test, Community Balance and Mobility scale, "Modified Ashworth Scale". Results: The pre and post-test values were treated statistically using SPSS software. Student's t-test and Wilcoxon signed rank sum test were used to study the significance. An analysis was done to assess the effects of the intervention on subgroups of CP also. Conclusion: Compound resistance training is effective to improve the gait parameters in spastic cerebral palsy children. Children with crouching demonstrated superior improvements in the gait parameters compared to children with hemiparesis and stiff knee.


: In this Research project, we analyzed the G+13, RC Building Frame structure with seismic Zone II and Zone III with considered soft, Medium and Hard soils by using Linear Static method in a Staad Pro V8i civil software as per IS 1893 (Part I). In this work we adopted various parameters like plan of building 24.02mX24.02m symmetrical along to X and Z direction respectively, Damping ratio 5 percent, importance factor 1.5 for important structure, Special RC Moment Resisting Frame as 5. The comparative analysis of this frame structure in the term of maximum displacement, maximum shear forces, maximum bending moment, maximum storey-wise displacement . Results found that, the seismic zone II and III with all type of soil conditions, the support reaction and also axial forces are same. The results in the terms of bending moment, shear force and node displacement, maximum as zone III in soft soil while minimum in Zone II in hard soil, it means that if zone varies lower to higher with hard soil to soft soil, the action of seismic effect is varies. And also observed that story wise displacement, if the number of stories increased , the displacement is also increased.


A new method to forecast customers' value is put forward using such data mining techniques as clustering and classification.The indicators reflecting old customers' value and business integrity are gained through analyzing the historical transaction data.Then,these old customers are clustered and further classified into different groups in accordance to their value indicators,i.e.,each and every old customer is assigned with a mark equivalent to its value.The naive Bayesian classification method is used to forecast new or potential customers' value,and a relevant customer development strategy is thus available.A numerical example is given to verify the effectiveness and practicability of the method proposed.


Direct imaging of widely separated exoplanets from space will obtain their reflected light spectra and measure their atmospheric properties, and small and temperate planets will be the focus for the next generation of telescopes. In this work, we used our Bayesian retrieval algorithm EXORELR to determine the constraints on the atmospheric properties of sub-Neptune planets from observations taken with a HabEx-like telescope. Small and temperate planets may have a non-H2-dominated atmosphere, and therefore we introduced the compositional analysis technique in our framework to explore the bulk atmospheric chemistry composition without any prior knowledge about it. We have developed a novel set of prior functions for the compositional analysis free parameters. We compared the performances of the framework with the flat prior and the novel prior and we reported a better performance when using the novel priors set. We found that the retrieval algorithm cannot only identify the dominant gas of the atmosphere but also to constrain other less abundant gases with high statistical confidence without any prior information on the composition. The results presented here demonstrates that reflected light spectroscopy can characterize small exoplanets with diverse atmospheric composition. The Bayesian framework should be applied to design the instrument and the observation plan of exoplanet direct-imaging experiments in the future.


In his 'On a Supposed Right to Lie from Philanthropy' (SRL) Kant makes the astonishing claim that one is not entitled to lie even to save a friend from a murderer. This claim has been an embarrassment for Kant's defenders and an indication of Kant's excessive rigour for his detractors. Responses to SRL fall into three main groups. The first of these groups, that of Kant's critics, claim that SRL demonstrates that Kant's ethical views are so rigorous that they become abhorrent in practice. The second group, Kant's defenders, argues that Kant's conclusions in SRL do not follow from his own ethical principles. The third group, made up of scholars who are generally sympathetic to Kant's position, attempts to explain why a liar is responsible (but an honest person is not) for all the bad consequences that follow from his act by providing an account of Kant's theory of imputation.


Recently multimodal learning has become a popular research topic because variety of types of sensors can be used to describe the events, for example, images and texts in the social network for disaster detection and response. It is useful because of different sources of information that data will cause heterogeneous problems. The kernel function can measure the similarity of data, and the fusion of different kernels can handle this problem well. This paper proposes a method based on multimodal deep kernel learning to detect specific categories of content posted on Twitter during a disaster for humanitarian response. Specifically, the convolutional neural network is used to extract image and text features, and obtain multiple kernel functions in each mode. Then a deep neural network is used to fuse multiple basic kernel functions corresponding to the two modalities. Finally, we use Support Vector Machine (SVM) for classification. Applying this method to a real disaster data set, and compared with the baseline, the results prove the effectiveness of our model.


Daily urinary excretion of acid maltase (12.78 +/- 2.10 units/24 hr/mg of creatinine, in 11 normal adults) was significantly decreased in ten patients with late-onset acid maltase deficiency (1.33 +/- 0.16 units/24 hr; P less than .001) and 11 heterozygotes (3.27 +/- 0.62 units/24 hr; P less than .001). Maximal inhibition of urinary acid maltase activity by antibodies against human placental enzyme was 53% in controls, 30% in heterozygotes, and virtually absent in patients. Investigation of pH curves and enzyme inhibition by antibodies confirmed the presence in the kidney of an immunologically distinct "extra" maltase enzyme active at acid pH. Whether acid maltase in normal urine originates in the kidney or cells of the lower urinary tract, the enzyme defect seems to be expressed in these cells in late-onset acid maltase deficiency.


The cloud-top pressure data assimilation technique (Kim and Benjamin 2000) developed for the Rapid Update Cycle has been implemented in an updated version with the 20-km version of the RUC (Benjamin et al. 2001). The GOES sounder-based cloud-top data remains the same as that used in 40-km RUC testing, but is now applied to the finer 20-km grid. In this paper, we report on the 20-km application of the RUC cloud analysis and also look ahead to the next step of assimilation of radar reflectivity. As described below, intercomparison of satellite and radar data will be necessary for quality control.


RECENT articles (I, 2, 3, 4, 5, 6, 7, 8) by the present author outline some of the implications that his prior techniques of measuring personality integration have for the study and understanding of both group and individual characteristics. In the present paper another method of measuring personality integration is reported and investigated. It appears to have additional implications for the study and understanding of group and individual characteristics. These implications are discussed herein, together with the evidence in support of the latter method for the measurement of personality integration.


In 1999, marginal and entire leaf necrosis, interveinal chlorosis, leaf puckering and crinkling, and stunted overall growth were observed in field-grown soybeans (Glycine max L.) in Essex County, Virginia. The soybeans had been fertilized with biosolids treated by the Zimpro™ wet air oxidation process at the Passaic Valley Sewerage Commission (PVSC) Newark, NJ wastewater treatment plant. Our objectives were (1) to replicate the symptoms in the greenhouse using soils collected from fields where phytotoxicity symptoms were observed and (2) to determine whether the causative agent was a constituent in the primary sludge or was produced by the Zimpro™ treatment process. We replicated the field phytotoxicity symptoms in the greenhouse in soybeans grown in Zimpro™ biosolids-amended field soils from Essex County and in soils amended with Zimpro™-processed biosolids obtained from PVSC. Soybeans grown in soil amended with untreated primary sludge from PVSC had phytotoxic symptoms that were generally atypical of those observed in the field but may have masked symptoms more similar to those of the field-grown soybeans. We were thus unable to determine whether the toxicant was present in the primary sludge or was a product of the Zimpro™ process. We were also unable to identify any common inorganic element as the cause of the reduction in the growth and development of the field-grown soybeans. We hypothesize that the toxicant may have been a persistent organic compound whose slow degradation in the soil was able to cause phytotoxicity several years after biosolids land application.


mellitus. Diabetic enteropathy refers to all the gastrointestinal complications of diabetes and may include dysphagia, heartburn, nausea and vomiting, abdominal pain, constipation, diarrhea, and fecal incontinence. Although not generally considered important causes of mortality in diabetic patients, these symptoms can be encountered in up to 75% of diabetic outpatients evaluated at a tertiary referral center. However, the prevalence of gastrointestinal symptoms among community diabetic patients is lower and will be discussed under the heading of epidemiology. Advances in Diabetic Gastroparesis


The directive 2003/88/EC concerning certain aspects of the organisation of working time is an essential piece of legislation in the field of labour law especially for SMEs. Working time is one of the main components of internal flexibility and a key feature for the competitiveness of small businesses. Therefore the way it has been implemented at national, sectoral and enterprise level is an important factor for small companies' economic success.


Abstract Water wells are important in providing water for rural populations that are far removed from municipal water supplies. Over 400,000 rural Albertans use water wells for domestic purposes. The responsibility of well water management lies with well owners. Perceptions of well water quality become important in influencing the adoption of well water management practices such as testing, treatment, and well maintenance. This study sought to understand perceptions of well water quality among rural Albertans living on acreages and farms. Semi-structured interviews were conducted with well owners. A thematic analysis was used to analyze the data. Overall, well water owners were satisfied with the organoleptic properties of their well water. Activities perceived as a hazard to well water contamination were mainly agricultural or oil and gas related. Most well water owners reported using some form of mitigation strategy. Well water owners reported knowledge of well water contamination events and the main illnesses associated with well water contamination were gastrointestinal illnesses. Perceptions of well water quality were influenced by several factors. Identification of these factors is useful in the development of well stewardship policy and could help inform well stewardship programs in the province.


Google Earth's reach extends from the layman who pins his home to the Earth, to the professional scientific journals asking for KML files of study areas. A revolution to the power of ten would have been witnessed by mankind if Google Earth was available during the era of Alexander the Great or Charles Darwin. The popularity and utilization achieved by Google Earth since inception into the cyber world in 2004 is simply marvellous. This all embracing coverage of Google Earth , which has elevated the status of maps and images from esoteric collections housed in dusty libraries to cutting edge technology is brought out well in this book.


Corruption is a dishonest or unethical conduct by a person (also company, state…) entrusted with a position of authority, with the intention to acquire certain benefits or advantages. Nowadays, corruption is present in all states and societies, and could be widespread in all legal and human relations. Corruption is mostly associated with embezzlement, bribery, coercion, extortion, blackmail… Therefore, the corruption is mostly of illegal nature. International and national anti-corruption initiatives and actions pay special attention to the fields where the impact of corruption affects the most vulnerable groups of people. On the international level the most active role is played by Transparency International, an international organisation fighting against corruption.


1. A prolongation of the shortest peroxidase stain-time is also seen in B1-avitaminotic rats. 2. The longer the B1-avitaminotic feeding, the more pronounced the prolongation becomes. It maybe prolonged to 9-10 seconds in the terminal stage. 3. A daily administration of 0.03 mgrms. of B1-crystals restored the prolonged stain-time to normal in 3 days averagely, that of 0.01 mgrm. in 5 days, and that of 0.005 mgrms. in 7 days. A prolongation was restored to normal in time longer than 7 days in the rats which had survived on a daily administration of 0.001 mgrm. of B1-crystals, while the prolongation was not restored to normal in the rats which had died in spite of an administration of the same dose. In the last series of experiment in which 0.0005 mgrms. of B1-crystals were used, the prolongation was restored at a much slower pace, in order to re-gain its former figures or even larger figures. At length they died in 5 days averagely without exception.


Intuitively, smaller class sizes sound like a good idea. Parents and teachers generally believe that smaller groups of students allow for more individual attention and result in improved student achievement. A consensus has emerged in the research that reduced class size makes a small but useful improvement to achievement in the early grades. However, reducing class size is complex: it impacts how classroom space is used, how teachers are recruited and allocated, and how students are grouped. Class size reduction is not a "magic bullet;" it is costly and must be done in concert with improving teaching practices.

Bob Hind, former managing director of Arriva Midlands, has been revisiting his youth, tracing as best he can journeys he first made nearly 50 years ago across the once mighty BMMO--Midland Red--empire. For the fourth of these, he heads east on a route he explored at Easter 49 years ago on Friday 1- April 1964 to places that become important in his professional life.


In 1979 the adaptation of a multi-media package, developed and produced by FWU Munich for the geography curriculum in the Netherlands was undertaken. This article will be concerned with the description of this task. The multi-media package under consideration Gletscher in den Alpen, (Glaciers in the Alps) was produced by the Institut fur Film und Bild in Wissenschaft und Unterricht (The Institute for Film and Pictures in Science and Teaching), Munich, FRG, in cooperation with the Vereinigung Schweizerischer Unterrichtfilmstellen, (Association of Swiss School Film Departments), Zurich. This package is aimed at pupils in the first year of secondary education, the so-called Sekundarstufe 1.


In the past two decades, laboratory x-ray analysis equipment has made significant strides, particularly toward higher resolution capabilities [1-2]. The major bottleneck to continued advances to achieving simultaneously achieving higher sensitivity, resolution, and throughput is the relatively low flux of x-rays at the sample for micro-characterization techniques such as SAXS, high resolution XRD, microXRF, and x-ray microscopy [3]. We present two major innovations of a microfocus x-ray source and a high resolution, high efficiency x-ray optic to enable delivery of flux comparable to second generation bending magnet synchrotrons.


We study an elliptic operator $L:=\mathrm{div}(A\nabla \cdot)$ on the upper half space. We know that if the matrix $A$ is independent in t-direction, which is the direction perpendicular to the boundary, then we have $\omega\in A_\infty(\sigma)$ and solvability of the Dirichlet boundary value problem. In the present paper we improve on the relatively stiff t-independece condition by introducing a mixed $L^1-L^\infty$ Carleson type condition that only depends on $\partial_t A$. Under this condition, we show that $\omega\in A_\infty(\sigma)$.


The pathophysiology of paradoxical elbow flexion contractures following neonatal brachial plexus injury (NBPI) is incompletely understood. The current study tests the hypothesis that this contracture occurs by denervation‐induced impairment of elbow flexor muscle growth. Unilateral forelimb paralysis was created in mice in four neonatal (5‐day‐old) BPI groups (C5‐6 excision, C5‐6 neurotomy, C5‐6 neurotomy/repair, and C5‐T1 global excision), one non‐neonatal BPI group (28‐day‐old C5‐6 excision), and two neonatal muscle imbalance groups (triceps tenotomy ± C5‐6 excision). Four weeks post‐operatively, motor function, elbow range of motion, and biceps/brachialis functional lengths were assessed. Musculocutaneous nerve (MCN) denervation and reinnervation were assessed immunohistochemically. Elbow flexion motor recovery and elbow flexion contractures varied inversely among the neonatal BPI groups. Contracture severity correlated with biceps/brachialis shortening and MCN denervation (relative axon loss), with no contractures occurring in mice with MCN reinnervation (presence of growth cones). No contractures or biceps/brachialis shortening occurred following non‐neonatal BPI, regardless of denervation or reinnervation. Neonatal triceps tenotomy did not cause contractures or biceps/brachialis shortening, nor did it worsen those following neonatal C5‐6 excision. Denervation‐induced functional shortening of elbow flexor muscles leads to variable elbow flexion contractures depending on the degree, permanence, and timing of denervation, independent of muscle imbalance. © 2012 Orthopaedic Research Society.

Hot-water treated cocoa bean shell(HWCBS) based diet was evaluated in respect of performance and physiological response of weaner rabbits. The treatment reduced the theobromine content of cocoa bean shell. Feed intake and weight gain were significantly(p<0.05) high in rabbits fed HWCBS up to 200g/kg. Water intake was highest in rabbits fed 400gHWCBS/kg. Rectal temperature and pulse rate also increased with increase in WCBS inclusion. Except for leucocytes count, Ca and urea, other haematological indices and serum Na, K, total protein and glucose decreased (p<0.05) in rabbits fed HWCBS based diet compared with the control group. The findings of this work indicate that hot water treated cocoa bean shell can be included in the diet of rabbit at 200g/kg for optimal performance.


The study was structured to determine the necessary factors, from the point of view of chemical control of foliar diseases, to obtain high quality wheat for bread production. The experiment in randomized blocks with six replicates tried to clarify the interaction between twelve cultivars and seven fungicide application programs, as well as its implications in the yield and quality of wheat grains. The results showed that the effects provided by fungicides in disease control, and their direct effects on the physiology of wheat plants, were decisive factors for obtaining high-quality wheat. The results also showed that diseases compromise the remobilization of nitrogen from leaves to grains. The differences between strobilurins and triazoles were evident in the control of leaf spot and leaf rust, in which triazole fungicides were more effective in controlling the leaf spot complex, when compared to strobilurins. However, effective control of wheat leaf rust was provided by strobilurins. The phenological stages of elongation and emission of spikes are critical times for the chemical control of leaf spot under conditions of monoculture. In addition, the fungicide application after flowering is essential for the appropriate management of leaf rust.


Automobile tires could be not in contact with wet road surface at a certain speed, which will cause dangerous phenomenon of hydroplaning. In this paper, the mechanism of automobile hydroplaning was discussed. Following an analysis on the state of the art of hydroplaning, a formula for computing hydroplaning speed was derived from the characterized parameters of tire-fluid-road. The result showed that the less mean texture depth, tire pressure and the more water film depth could incur lower hydroplaning, which is helpful to make a decision of controlling driving speed on wet roads.


Freeing the Presses: The First Amendment in Action. Timothy E. Cook, ed. Baton Rouge: Louisiana State University Press, 2005. 208 pp. $39.95 cloth. $18.95 pbk. "Thought provoking" is a book review cliche often used when, in fact, no thoughts are being provoked. Timothy E. Cook's wonderful collection of essays and articles deserves the label, however, along with the close attention of communication scholars. Cook, a political communication professor in the Manship School of Mass Communication at Louisiana State University, has edited the papers from a 2003 LSU symposium on the intersections between the legal theory of freedom of the press and the empirical evidence of media performance. Six social scientists wrote papers exploring press freedom in the United States and what the media actually do-in the past, the present, and the foreseeable future. Four LSU scholars wrote essays that pull the research together into a cohesive book. Freeing the Presses is full of surprises. The authors challenge the conventional wisdom on media and First Amendment contributions to the robust debate of public affairs. They raise new questions and suggest new answers to old questions. One especially interesting article is Frederick Schauer's exploration of the impact of the actual malice defense to libel on the media's performance. The U.S. Supreme Court created the actual malice defense, which requires many libel plaintiffs to prove an allegedly libelous story was published with knowledge of falsity or with reckless disregard for the truth, based on the assumption that without it the news media would be afraid to engage in the kind of uninhibited, robust, and wide-open debate of public affairs that the Court desired. Schauer, a professor in Harvard's Kennedy School of Government, tested that previously unquestioned assumption. He compared libel laws and media performance in Australia and the United States. He found that although Australia had no actual malice defense to libel and had other libel rules more stringent than those in the United States, the Australian media were every bit as aggressive in their news coverage of public issues as the U.S. media. He also compared libel laws and media performance in Kansas and its neighboring states in the early 1900s, when Kansas provided the media with an actual malice defense against libel suits but the other states did not. Again Schauer found no differences in media performance. He offered an interesting variety of explanations for his findings, ranging from the strong professional norms that support aggressive news reporting to the prevalence of libel insurance. …


The monitoring and control of projects are processes that consist in the review and comparison of the progress with the projected performances and actions with the purpose of concluding the project within the established. However, the realization of these processes generates a consumption of time, inaccuracies and lack of easy understanding in the preparation of progress reports due to the lack of automation, integration and synthesis of traditional monitoring and control systems.

This research work proposes the implementation of a monitoring system and the control of time and cost in the civil works of a petrochemical project, with the purpose of evaluating the effects of the monitoring and control processes of projects.

The BIM system was implemented especifectly in the execution of the civil works of the cost center Prefabricated Pipe Rack of the Gasolinas petrochemical project in two phases, which as a whole consisted in a prior evaluation of its sub-projects to determine the feasibility of the implementation of the system stages; then proceeded to develop the stages, which in the synthesis are 3D modeling, the connection and automation of the flow of information and finally the visualization of progress.

The BIM implementation proposal is a system that stores the information obtained from the daily progress of work in cost and time parameters created according to the structures of the budget and schedule formats, to be later processed by the Revit modeling program. of Autodesk. This processing consists, first of all, in calculations and the organization of data that is then exported to the budget and schedule formats, through connection tables; and second, the update of advance views through the operation of conditional parameters and formulas for calculation and synthesis of information. On the other hand, this system is also supported by calculation tables and project management programs, which process the data exported from the model by executing calculations of budget and planning respectively. The documentation of the support of the progress reports is obtained from these two main processes.

The implementation of the proposed system allowed to carry out the monitoring and control process in a daily and timely manner, respectively; facilitating the obtaining of the measurements, costs and percentages of advance with precision, as well as connecting the budget and chronogram with a single source of information; avoiding double counting and omissions, due to the large number of variables, in the calculation of the measurements, thus avoiding the loss of time by corrections; giving a visual understanding of the current status of the project, thanks to the 3D views, thus decreasing the need for construction managers to make site visits; and finally, allowing us to deal with a large amount of detailed information, mainly thanks to the 3D model due to the use of parameters and filters.


In this paper, we consider the problem of interference mitigation in the downlink of multicell networks via base station coordination. In this paper, a simple and efficient scheme for interference management based on potential game is proposed. The main emphasis of this paper is placed on the problem of users' quality of service (QoS) in order to maximize the efficient throughput of system. Meanwhile, a pricing factor is introduced which is proportion to the co-channel interference to other base stations. Furthermore, an improved gradient projection rule with variable step size and Jacobi iterative algorithm are utilized to solve the optimization problem. Pareto optimal is verified by using "price of anarchy" as an optimize performance indicators in potential game. Simulation results show that our proposed scheme can significantly improve the performance of multicell networks.


163 necessary and the monograph might have been more interesting and penetrating if he had instead engaged thoroughly with a few of the more well established and respected interpretations. Nevertheless, the monograph is important not only because of the refreshing social identity hypothesis but also because it further demonstrates the vitality of inter-disciplinary methods in biblical studies.

A novel MgSrLa8 x(SiO4)6O2:xEu (MSLSO:xEu) phosphor was synthesized through a high-temperature solid-state reaction. The crystal structures, luminescent properties, fluorescence decay time, and oxygen vacancies were investigated systemically. XRD analysis shows a typical oxyapatite structure with the space group P63/m. Europium can enter crystal matrices simultaneously in the form of Eu 3+ and Eu and occupy nonequivalent crystallographic positions in a lattice, thus forming various optical centers. Under ultraviolet light excitation, the phosphors simultaneously show the blue-green emission of Eu and the green-yellow-red emission of Eu. The optimal doping content of Eu is 7.5 mol% (x 1⁄4 0.075). White light can be realized with a CIE coordinate of (0.3664, 0.3260) by adjusting the concentration of Eu. The lifetimes of Eu and Eu in this study are considerably longer than those in other references. The results suggest that the MSLSO:Eu/Eu (0.075) phosphor is a promising candidate for white LEDs.

This paper analyzes the impact of the COVID-19 government stringency index on foreign investment, at the onset of the pandemic. Through a Robust Least Square regression estimation, we highlight that the relationship between foreign investment and the government containment measures displays a significant cross-country heterogeneity that depends on the level of the pandemic risk in the country. Foreign investors have indeed tilted their asset allocation towards those countries that implemented strong containment measures (as measured by the government stringency index) in the presence of a high risk (as measured by the risk of openness index). Conversely, they have shown a lower propensity to invest in assets issued by countries either adopting weak stringency measures despite a high risk of openness, or implementing drastic stringency measures in the presence of a relatively lower risk of openness. The above findings suggest the following interpretation: the government stringency measures and the pandemic risk have jointly affected foreign investors' behavior, which appeared relatively more prone towards assets issued by those economies better calibrating the policy interventions according to the pandemic harshness.


Abstract An optomechatronics design project for the pilot of an Arecibo-type large spherical radio telescope for the square kilometre array (SKA) is proposed, concentrating on the feed-supporting system with large-span cables. The feed-supporting system consists of two parallel manipulators: the parallel cable manipulator, which provides a large workspace for the trajectory tracking and realizes the coarse tracking control, and the fine-tuning Stewart platform, which connects the parallel cable manipulator to the cabin structure and implements the high-accuracy requirement of tracking. In order to improve the real-time controllability, an approximate kinematics model of the parallel cable manipulator is developed using straight links to approximate the cables based on static equilibrium at low tracking velocity. A control strategy for the feed-supporting system is proposed using the independent control method, and the corresponding tracking accuracy of the coarse control and fine tuning is presented. The simulation results have supported the rationale of this approximate model of the parallel cable manipulator and the feasibility of this mechatronics design project for the SKA.


We present an appropriate methodology and results for using third-harmonic generation (THG) modality for nondestructive high resolution imaging measurements of varnished structures in model painted artifacts. Detection takes place in the reflection mode, demonstrating the ability of the technique to be applied to the evaluation of original artworks. Furthermore, multi-photon excitation fluorescence images were obtained, providing complementary information related to the identification of the chemical composition of the artifacts.
