I have also worked on the layout of the volume with Graphic Designer Don Addison.


Optical associative memories have been demonstrated previously that store an accumulation of outer products. Each outer product represents an associated vector pair. In this paper we use a joint transform correlator with a liquid crystal (LCLV) to form the outer products which are then accumulated by mapping with Argon light onto electron trapping material (ETM). Argon light causes electrons to be trapped at the ETM for later recovery. Further we show for the first time that we can remove the outer product for any one of the associated pairs from the accumulated stored matrix of accumulated outer products. This is accomplished by placing the pair to be removed at the input and using IR instead of Argon light to map the outer product onto the ETM. IR light removes stored electrons in the ETM. Experimental results show the practicality of this approach.


The mobile phone-based Experience Sampling Method (ESM) enables in situ recording of human behaviour and experience by querying users, via their smartphones, anywhere and anytime. Sampling can happen on a previously unimaginable scale, and across a diverse pool of participants. Therefore, mobile ESM is not limited to capturing users' manual responses, as the surrounding context can be automatically captured by mobile sensors. However, obtaining high quality data with ESM is challenging, as users may fail to respond honestly, or may even ignore the questionnaire prompts if they perceive the study as too burdensome. In this paper, we discuss the potential of using interruptibility prediction models to deliver mobile ESM questionnaires at opportune moments, and thus improve the effectiveness of a study. We examine context prediction and interruptibility inference, which are fundamental challenges that need we need to overcome in order to make mobile ESMs better aligned with a user's lifestyle, and consequently paint a truthful picture of a user's behaviour.


The present study examines why the nasal prefix Nin Basilectal Jakarta Indonesian (bJI) is produced less frequently than the null affix (Ø-), although both prefixes function as active voice markers. This study firstly investigates the possibility that Nin bJI is also a progressive aspectual marker. N-verbs have the characteristics of non-stative verbs—which could qualify Nto become a progressive aspectual marker. However, the following two facts contradict the supposition: firstly, Nverbs can be modified by a perfective aspectual marker dah/udah. Secondly, in some contexts, the presence of the prefix Ncan derive the past tense interpretation. In the present study, I argue that Øand Nhave different discourse functions. This argument is based on the fact that N-verbs are generally used in narratives; in contrast, Ø-verbs are inappropriate to be used in narratives. Furthermore, N-verbs generally cannot be used in direct (positive) imperatives; on the other hand, Ø-verbs freely in direct and indirect imperatives. In addition, in a question in which the active verb co-occurs with a modal, when the active verb is affixed by the nasal prefix, it is the modal which is being questioned. In contrast, when the verb is affixed by the null affix, the question focuses on the action. In line with the above argument, it is assumed that adult speakers produce active verbs with the null affix more frequently than those with the nasal prefix when talking to young children because of the nature of child directed speech.


With the development of technologies such as computer vision and speech recognition, human-computer interaction technology has gradually matured and has a broad development prospect in many fields. In this paper, a multimodal human-computer interaction system based on Bayesian classification algorithm is constructed, which collects human posture and speech information of the interactor during the interaction process, and determines the interaction intention by the information of three modalities: finger direction, face orientation and speech of the interactor, without touching or wearing any equipment during the whole interaction process. The head pose estimation method is introduced and used as the face orientation modality for the multimodal interaction system; meanwhile, the DBSCAN (density-based spatial clustering) algorithm is used to select the interaction frames so as to filter out the unstable interaction frames and improve the system robustness. In addition, a multimodal data fusion algorithm based on Bayes' theorem is proposed in this paper to improve the interaction accuracy. Experiments show that the proposed multimodal HCI system has better robustness and higher accuracy than the single-modal interaction and decision matrix fusion.


MANET(Mobile Ad hoc Network) is a collection of two or more nodes equipped with wireless communications and constrained by the factor of energy limitation. The running out of energy on some nodes may bring down the performance of network seriously. For solving the problems above, this paper uses completely separated Node-Disjoint multipaths from a source to a destination as many as possible. And, based on average, minimum or variance of energy values on the each multipath, the packets are distributed on paths. Generally, collecting methods for energy information can be classified into two main categories, Static and Dynamic. As the different energy values collected, the packet distribution methods are classified into six criteria, Static-Average, Static-Minimum, Static-Variance, Dynamic-Average, Dynamic-Minimum and Dynamic-Variance respectively. The performance of the packet distribution methods and that of AODV are compared by NS2 simulation.


A static vector GIS with layers each containing geometry representing the state of real world phenomena can be extended to handle changes in the phenomena. So, if you have a property GIS storing land parcels it is possible to store multiple 'states' for each land parcel, for example, to deal with the subdivision of a land plot into two or more parts. Hornsby and Egenhofer (2000) presented a formal scheme for spatio-temporal knowledge representation, based on possible changes to phenomena, modelled as discrete objects at a high level of abstraction. In their scheme objects representing phenomena can be in the following states: existing; not existing with no history of a previous existence; or, not existing but with a history of previous existence. Changes from one state to another are defined as 'transitions', which in total allows nine combinations: continue existence without history; create; recall; destroy; continue existence; eliminate; forget; reincarnate; and continue non-existence with history.

Many studies show that the Student Teams-Achievement Divisions(STAD) of cooperative learning helps improve the students' learning achievement. The objective of this current study is to investigate whether STAD actually benefits the students with lower academic achievement, meanwhile, to understand the corresponding factors influencing on the learning achievement, and to show the course's conducting process. The study invited 47 sophomores at one University of Science and Technology to participate in a three weeks' STAD's teaching project. According to the scores of mid-term exam, they were sorted into three groups. The groups were divided base on high, medium, and low academic achievement and then were evenly divided into 6 groups. The individual participant who had more progress and a higher score was awarded in time every week. Finally, each group got the rewards depending on the total progressive scores after three weeks. The study results presented that there was (1) a significant difference between pre-test and post-test scores. (2) a significant difference between the participant's learning achievement and the influence factors, including the learning sheet, the heterogeneous grouping, and the alienation behavior. (3) a significant difference between the attendance and the heterogeneous grouping of the participants (4) a very different look exists in the participant behavior, the group discussion, and the learning achievement for the high-score and low-score participants. This current study's results support the effect of STAD approach and show the fact that the low-score participants cannot have significant improvement in STAD. There are four parts put forward to discuss, which includes the work-division and cooperative ability for the group, remediating the background knowledge and exciting the inner motivation, the various assessments for learning, and the improvement of the teacher's teaching competence. This study also suggests that the rate and duration for the STAD's conduction can increase to understand more about its effectiveness and the corresponding influence in the future.


In article, the geological and structural features, structure and morphology of mineralized ore zones and ore bodies of the Petropavlovskoe lode gold deposit are discussed. This deposit is located within the Toupugol-Hanmeyshorskiy ore region at the Polar Urals (Yamal-Nenets Autonomous District). Two types of ore occurred in the area: gold-sulfide (the most important for gold ore mineralization) and gold-low-sulfide-quartz. Structural and morphological, mineralogical and geochemical features of the Petropavlovskoe gold deposit including spatial association of gold mineralization with the bodies of porphyry intrusive phases, stockwork structure of gold mineralized zones and ore bodies, volumetric disposition of ore-metasomatic zoning, and the structure of allocation of ore concentrations refer the deposit to the porphyry type.


In the chapter the autors presented analysis of systems of early-developmental support and education based on received materials. In spite of an attempt of objectivation it should be stressed that individual editors of the monograph perceived the reality in different ways and the presented view is a consensus agreed during the discussion. However, the analysis revealed specific gaps and the need for scientific research in leading fields, both in the period of early support and school education. In our opinion the largest number of changes, changes confirmed by research, towards "Evidence-based Practices" are needed in school education.


Monodisperse colloidal CdSe nanocrystals (NCs) with different sizes were synthesized, and the time-resolved photoluminescence (PL) spectra were measured to explore the evolution of surface states during the NC's growth. The PL quantum yield, fluorescence lifetime, and the surface-related emission had the identical size dependence. The role of the nonradiative/radiative surface states in the PL carrier dynamics was discussed.


A series of model pile tests have been performed in the geotechnical centrifuge at the University of Western Australia to study the behaviour of driven piles in homogeneous sand. Open, sleeved and closed-ended piles have been driven by a miniature pile driving actuator into silica flour of varying densities. The model pile was fully instrumented, allowing strain gauge data to be monitored during dynamic and static testing. Analysis of the load tests revealed that the shaft friction increased approximately linearly with depth at a low rate, but with a marked increase close to the pile tip. The average shaft friction for the closed-ended tests was shown to be greater than for the open-ended tests. For all tests, the average values of shaft friction were greater than those suggested by current guidelines for design of offshore piles (API RP2A), and the ratio of tensile to compressive shaft capacity was always below unity. The end-bearing resistance normalized by the cone tip resistance was shown to reduce wi...


Multiple coal seams and interbedded rock assemblages formed in vertical progression due to the influence of multiple stages of sea level transgressions. Based on mercury injection experiment, low temperature liquid nitrogen experiment, porosity and permeability experiment and breakthrough pressure experiment, the vertical variation characteristics of coal‐bearing strata in Gujiao block are explained in detail. The results of the mercury injection and low temperature liquid nitrogen experiments show that the pore structure characteristics fluctuate with increasing depth in the strata, with fewer micropores followed by transition pores. The BET specific surface area and average pore diameter of the Shanxi Formation are generally larger than those of the Taiyuan Formation. Due to the continuous cyclic sequence stratigraphy changes, the porosity, permeability, breakthrough pressure and breakthrough time of the samples show a certain cyclicity. Within the same sequence, the porosity is larger, and the permeability is smaller near the maximum flooding surface. Although the permeability of the sandstone samples is higher, the porosity is lower, and the breakthrough pressure and breakthrough times are greater. The strata in the study area formed in an oxidized environment that was affected by freshwater, and the pore structure of different lithologies is quite different. After the formation of sandstone, the intergranular pores generally underwent filling with secondary quartz, clay minerals and organic matter, resulting in low porosity and permeability.


The grammatical functions of the Chinese prepositional phrases can be used with the predicate or the predicate phrases,mainly with the phrase having the verb as the head word and occasionally with a conjunction or a functional word.As for the syntactic functions,these prepositional phrases are used mainly as adverbial,sometimes as a modifier at the beginning of a sentence,and occasionally as subject,object or complement.


The article presents two cases in which the appropriation of technological innovations leads to renewed economic and power relations, which in turn reinforce local transformation processes of governmental management and of barely-regularized economic activities. The workings of a command and control system in Rio de Janeiro and the delivery structure of a "food tech" company reinforce authoritarian or violent modes of operation, all the while enabling the development of illicit activities linked to the "militianization" of crime, as well as of security forces, of economic activities and of politics in present-day Brazil. Based on these cases, we present a discussion on a few specificities concerning the technological appropriation of certain devices in the Global South and its effects on the production of society and social relations.

Abstract Markers are substances which are artificially introduced into ecosystems in small quantities and which have no acute effects on energy flow. A marker might be a pollutant which affects life significantly only over long time frames. Alternatively, a marker might be a benign substance easily detected in small amounts and introduced in order to trace energy flow and so evaluate energy flow models. The flow of markers can be modeled in parallel to energy flow by assuming that energy flowing out of a compartment carries with it a proportional mass of marker. The purpose of this paper is to derive qualitative conditions on the food-web structure and the consumption functions of a model which guarantee stability of energy and marker flows. We will show that many consumption functions used in mathematical ecology lead to sign-stable models of energy flow and furthermore that such models enjoy inherent stability of associated marker flows.


In this study, molecular imprinted polymers targeting the potent antibiotic ciprofloxacin were prepared for the first time using renewable resources. Lactic acid maleic acid ester, methylene bisacrylamide, potassium persulfate and N, N, N', N' tetramethylenediamine were used as functional monomer, crosslinker and initiator, respectively. The chemical structure of the synthesized polymers was characterized by Fourier Transform Infrared spectroscopy, and the thermal behavior was characterized by Thermogravimetry. Developed molecularly imprinted polymers can be used in separation, catalysis, and sensor applications, and as drug delivery systems.


James Gregory (or Gregorie as his name was usually I spelt in the seventeenth century), astronomer and geometer, was born in November 1638 at the Manse of Drumoak, on Deeside, near Aberdeen: he died in October 1675 at Edinburgh, of a sudden illness and at the height of his intellectual powers. Among his contemporaries he was held to be second only to Newton, who was four years his junior. Both Gregory and his wife Mary Jamesone, who was his second cousin, came of a family remarkable for extraordinary talent which persisted throughout two centuries and seven generations. James was a grandchild of David Anderson of Aberdeen, a man of considerable sagacity in mechanics, who earned the name ' Davie/do/a'/thing,' whether for constructing a church spire and raising the great bells into position, or for removing a dangerous rock from the harbour mouth by harnessing it to the tide. His brother Alexander was the leading Scottish mathematician at the beginning of the century who had edited and expounded the trigonometry of Vieta, the father of symbolic algebra. Janet, the daughter of David, married the Reverend John Gregory, a descendant of the Highland clan Macgregor of Roro, the younger branch of the Glenlyon family. Something of their wild fighting spirit was inherited by each of their academic descendants. Mary was the daughter of George Jamesone, a distinguished portrait painter, who was a nephew of David and Alexander.


[Objective] To assess the safety of patients with pheochromocytoma receiving iodinated contrast media injection during enhanced CT examination.[Methods] The systolic pressure,diastolic pressure,heart rate of 205 patients with suspected diagnosis of adrenal pheochromocytoma were continuously recorded 10 minutes before the examination,and 5 minutes,10 minutes,20 minutes,30 minutes,and 24 hours after the examination.Among them,50 patients whose diagnosis were confirmed by pathology as pheochromocytoma were set as group A.Others were excluded pheochromocytoma and 50 were extracted from them and named as the control group(group B).The changes of blood pressure and heart rate were analyzed at different time points.[Results] The changes of blood pressure and heart rate before and after the examination in two groups showed no significant difference,as well as those at different time points between two groups.[Conclusions] Intravenous injection of low-osmolar iodinated contrast media does not induce changes of blood pressure and heart rate in pheochromocytoma patients.Pheochromocytoma patients have the same safety as patients with other adrenal carcinoma during enhanced CT examination.

We show that for a linearly compact module over a local ring (R,𝔪), the concept of co-support of modules provided by Melkersson is equivalent with Yassemi's concept. We also introduce the definition of coartinian modules which is in some sense dual to Hartshorne's definition of cofinite modules and show that is I-coartinian in case M is a semi-discrete linearly compact R-module with Ndim M=d> 0.


Wakefield oscillations created by the ion wakefield existing below a dust particle within the plasma sheath generated above a powered lower electrode in a GEC rf reference cell carry information about the plasma sheath, the dust particle charge and the speed of the streaming ions. An experimental method to investigate such wakefield oscillations is discussed.


Cassava (Manihot esculenta Crantz) is a tropical root crop that serves as a food staple and a vital income source to resource deprived farmers in the tropics. Despite its importance, cassava production and consumption is faced by a myriad of biotic/abiotic constraints. Genetic transformation which can be applied to mitigate these challenges however has as a prerequisite the availability of robust regeneration systems. This study evaluated the effect of explant type and hormone regime on somatic embryogenesis and regeneration of Kenyan cassava cultivars. The embryogenic competence of immature leaf lobe and stem explants of three cassava cultivars was determined by culturing them in MS medium supplemented with picloram (4, 6, 8 and 10 mg/l).  The optimum media composition for embryo maturation, germination and plant recovery was assessed by culturing embryos in media supplemented with varying concentrations of 6-Benzylaminopurine (BAP), α–Naphthalene acetic acid (NAA) and Gibberellic acid (GA3). Somatic embryo formation frequencies in leaf explants were significantly higher (P≤0.05) than in stem explants. Embryo formation rates were found to increase with increasing concentrations of picloram. Cultivar 08/080 gave the least response to embryogenesis while embryogenesis rates for cultivar 08/274 were similar to the control cultivar TMS 60444. Maturation and plant recovery rates differed significantly with regard to the ratios of BAP, NAA and GA3 in the maturation media. The optimal medium for embryo germination and plant recovery was supplemented with 1 mg/l BAP, 0.02 mg/l NAA and 1.5 mg/l GA3. This optimized regeneration protocol can be coupled with mutation breeding or genetic transformation to improve the cassava germplasm.

 Key words: Cassava, explant, regeneration, somatic embryogenesis, plant growth regulator.


Kim Bero, MS, RKT Kinesiotherapist Physical Medicine and Rehabilitation Service James A. Haley Veterans' Hospital Tampa, Florida PARKINSON'S DISEASE (PD) was first described as "shaking palsy" by James Parkinson in 1817. Currently, this debilitating neurodegenerative disorder affects over 1 million people in North America. The primary treatment of PD is drug therapy. Levodopa has remained the gold standard for drug management of PD. The appropriate time to initiate levodopa therapy is controversial, as long-term use of levodopa is associated with adverse reactions. Development of newer agents such as sustained-release levodopa, direct-acting dopamine agonists, monoamine oxidase type B (MAO-B) inhibitors, and cathecholO-methyltransferase (COMT) inhibitors has provided new options to improve symptoms and quality of life while minimizing adverse effects. Monotherapy, or use of a single medication, may alleviate symptoms in early stages of the disease. However, as the disease progresses, maintaining physical function and minimizing adverse effects often require multiple medications. Optimal medication management is an ongoing process of drug selection and dosage titra-


Obstructive sleep apnoea (OSA) describes the pathological narrowing and collapse of the upper airway in recurrent episodes during sleep. This can result in a variety of symptoms that markedly affect quality of life. In addition, other chronic complications, most significantly the development of long‐term cardiovascular disease, are increasingly becoming recognised.


The rise of transnational systems and networks of governance and norms since the 1990s and the emergence of the so-called "global civil society" hold out promises of equity for LGBT advocates and marginal groups in East Asia as pride marches, lesbian and gay cultural events, and booming queer Internet communities corroborate the impression that queer Asia may be much more than a concept. Yet, there is a growing retrenchment in the same region as various states take up measures quite inhospitable to queer existence. Christian NGOs in particular are quite aggressively raising social discontent and mobilizing opposition against the growing visibility of gay lifestyles and the equity demands launched by queer activism. The present essay analyzes this new '"reign of civility'" and its construction of "child protection" as a universal imperative; it also demonstrates how developments in juridification are suturing up global governance, East Asia's liberal states, and conservative NGOs into a new power bloc that fosters anti-queer and anti-sex climates in the region. ・ No prior Registration necessary. ・ Lecture will be in English with no translation ・ Contact: Sophia University Institute of Comparative Culture office at email@example.com or by phone 03-3238-4082.

The biosynthesis of sn-glycerol 3-phosphate (glyc- erol-P), a precursor for the synthesis of phospholipids, in Escherichia coli is accomplished in a single step by reduction of the glycolytic intermediate, dihydroxyac- etone-phosphate. The enzyme which catalyzes this re- action, the biosynthetic glycerol-P dehydrogenase (EC 220.127.116.11), is strongly inhibited in vitro by glycerol-P. The inhibition by glycerol-P, referred to as feedback inhi- bition, was altered by a mutation in the structural gene for the glycerol-P dehydrogenase, which rendered the glycerol-P dehydrogenase feedback-resistant. The wild feedback-resistant dehydrogenase conventional and rose.


Purpose: To improve the hydrophilic property of myricetin by complexing it with hydroxypropyl-βcyclodextrin (HP-β-CD) Methods: The complexes of myricetin and HP-β-CD were prepared in both water and ethanol. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and x-ray diffractometry (XRD). Results: The content of myricetin in the complex prepared in ethanol (3.71 %) was higher than that prepared in water (1.43 %). Characterization studies indicate that myricetin in the complex was molecularly dispersed in HP-β-CD matrix. Conclusion: Ethanol is the better solvent to prepare the complex of myricetin and hydroxypropyl-βcyclodextrin. Myricetin and HP-β-CD in the complex are combined by non-covalent bond, and thus did not form a new compound.


CAFFEY and Silverman,1 in July, 1945, published the following description of a new syndrome entitled "infantile cortical hyperostoses": The principal features of the disorder include: onset in the early part of the first year; tender swellings in one or more of these sites — face and jaws, scapular regions and extremities; and multiple scattered hyperostoses demonstrated roentgenographically in bones adjacent to the tender swellings and also in several other bones whose overlying soft tissues appear to be normal, clinically and roentgenographically.... Biopsies of the affected bones in 3 cases showed only hyperplasia of the lamellar cortical bone. Fever was noted . . .


In France, in traffic accidents one fourth of fatalities and one third of the severely injured involve two-wheelers. Among these, motor-cycles represent three-fourths and bicycles one fourth as concerns fatalities and respectively 5/6 and 1/6 as concerns severely injured. Head injuries are the most severe and constitute the major cause of death. This paper analyzes 39 cases of traumatic coma subsequent to two-wheel accidents; 20 two-wheelers were helmeted and 19 were not. All the patients were admitted to the neurological intensive care unit of the neurological hospital in Lyons. For the covering abstract of the conference see TRIS 393117. (TRRL)


TiAl3/7075 composites were fabricated by in situ synthesis via ultrasonic treatment. A kinetic model of the reaction process acted by ultrasonic wave was built with mathematical calculation. The calculations show that the reaction time comparing with that of no ultrasonic treatment is greatly reduced. Some influencing factors on the reaction rate were analyzed. The results show that granular TiAl3 phases present in the composites and distribute homogeneously. Ultrasonic oscillation can increase the diffusion coefficient of aluminium atom,decrease the thickness of boundary layer and the size of titanium particle,all these accelerates the velocity of reaction.

'Spoiler alert' : This editorial speaks to that of Dr. John Williamson that is published in this years issue. I have made some effort to avoid revealing too much of the "plot" but those of you who prefer to enjoy the mystery of the disappearing/appearing slow learner as it is intended to unfold are advised to read Williamson's article before this one.


Water holding capacity (WHC) of muscle is one of the most important factors for evaluating the meat qualities and has closely correlation with other characteristics such as color, flavor and tenderness. It is of great value to investigate the influential factors on WHC of meat for improving meat quality and reducing economical losses caused by drip loss in muscles. But very little work has been done in this field throughout our country. Therefore, the latest progress in the study of slaughter factors on muscle WHC at home and abroad is reviewed in this article.


Introduction : one of the most significant concerns after third molar surgery is the post-surgical dental pain. Regarding the efficacy of the Novafen and Naproxen in pain control treatment, it is important to compare the effect of each of these medications to decide which one should be used. Aim: The aim of this study was to compare the effect of Novafen and Naproxen on pain management in patients after surgical removal of impacted mandibular third molar. Methods and Materials : This study was a clinical trial that was performed as a split mouth and double-blind on 20 patients (12 females and 8 males) with a mean age of (24.2±5.8) which had surgical extraction of impacted mandibular teeth in two different dates. Novafen (Acetaminophen 325mg, Ibuprofen 200mg, and Caffeine 40mg) and Naproxen 500mg were assessed blindly in each date as a pain control treatment. The pain intensity was determined by VAS (Visual Analogue Scale). In this study, data were analyzed based on Mann-whitney U-tests. Results : The mean pain in Novafen group was lower than Naproxen group 4, 8 and 12 hours after surgery (p<0.001). But after 24 hours, pain in both groups were the same and there was no statistically significant difference (p<0.2). Conclusion : The pain in Novafen group was meaningfully lower than Naproxen group hence Novafen can be used as a more effective therapy rather than Naproxen in dental surgeries. Keyword : Naproxen, Novafen, tooth, impacted.


The existing tunnel lining structure is easily affected by geological conditions, disturbance in the early stage of construction and operation in the later stage. This paper analyzes the main factors affecting the lining structure diseases of existing tunnels from three aspects of engineering construction, natural environment and engineering geology, starting from 13 independent factors affecting the lining structure diseases of existing tunnels. First of all, the index system of the formation factors of lining diseases in the reconstruction and expansion tunnel is established by using the analytic hierarchy process (AHP), and the hierarchical index system is put forward. Based on AHP-Extenics model, the evaluation method of lining structure disease of existing tunnel is proposed. Then, combined with engineering practice and expert scoring, the weight of safety evaluation index is determined, and the safety evaluation index and weight are expanded by using correlation function. Finally, the disease evaluation grade of the existing tunnel lining structure is obtained. This method uses the formal Extenics comprehensive evaluation model, which makes the calculation results more objective and provides a new method for the disease evaluation of the existing tunnel lining structure.

A simplified methodology is presented to estimate the required pull loads on polyethylene pipe installed by a mini (or midi) - HDD process. A simplified procedure is also presented to evaluate the potential collapse tendency of the PE pipe during the installation or post-installation phases. The methodology and associated formulae are based upon approximations to the more complex set of equations and procedures provided in ASTM F 1962, Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossings. The objective is to provide a convenient means of identifying potentially problematic mini-HDD installations and/or to aid in the pipe (DR) selection process, in contrast to the extensive planning or analytical investigations characteristic of typical maxi-HDD projects. The proposed mathematical model reflects the major route parameters (bore length, planned bends) and buoyant weight for an empty PE pipe, and also accounts for unplanned curvatures (undulations) resulting from path corrections in a typical mini-HDD installation.


The aim of this research was to study the meaning of the hearing impairment and of the hearing aids usage by the elderly. To understand the production of meaning in daily life we used a method of Discursive Practices Analysis (Spink, Medrado, 2004). Through the careful reading of the transcription of nine interviews we established five categories to the data analysis. At the category definitions, hearing impairment received the meaning of contact restrictions with others and hearing impaired received the negative meaning of less capable. At the category causes, hearing impairment was mainly related to advanced age, receiving the meaning of fatality. At the category hearing aids usage, these equipments received the meaning of instruments that make possible the re-establishment of the contact with others, but not completely, because communicative difficulties still last. At the category social, were referred the negative reactions of the participants and the others when communicative difficulties appear, emphasizing the escape from the situations where communication is demanded. They also referred the social pressure for the hearing aids usage, showing that these difficulties also affect those who surround them. At the category affectivity, for the hearing impairment were referred feelings such as fear, isolation, nervousness and shame. For hearing aids usage were referred joy, well-being sensation, concern and shame. Such emotions have disclosed the impact of hearing impairment and hearing aids usage at their lives. Therefore, we concluded that the meanings attributed to hearing impairment and hearing aids usage are mostly related to the stigma and influence on its acceptance, affecting the rehabilitation process of the elderly.


Principles and approaches to a choice by the Russian pharmaceutical companies of the markets for the international activity are considered. Process of a choice of the foreign market includes four stages: 1) factor analysises, 2) determining of criteria of an estimation and actually an estimation by criteria, 3) choice of the most long-range market and an estimation of its potential, 4) estimation of risk.


Objective:To study the risk factors in obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods:Related parameters for 192 cases of patients with snoring were analysised,including the sleep disorders qestionnaire,neck circumference,hight,weight and polysomnography(PSG).The relationship between the severity of OSAHS and gender,age and obesity was studied.Results There was significant difference between the male and female patients with OSAHS in symptoms,severity of the disease and the sleep disorder parameters.The age of patients with OSAHS was mainly in 31 to 60 years old.The body mass index(BIM),neck circumference,waist/hip rate was highly related to apnea/hypopnea index(AHI),oxygen desaturation index,the lowest arterial oxygen saturation.Conclusion:Gender,age and obesity were the risk factor for OSAHS.


The kings of medieval England, besides using history for the entertainment of themselves and their courts, turned it to practical purposes. They plundered history-books for precedents and other evidences to justify their claims and acts. They also recognised its value as propaganda, to bolster up their positions at home and strengthen their hands abroad. Although they rarely resorted to the production of official histories, they sometimes brought their influence to bear on the writing of non-official ones, to ensure a narrative favourable to their cause ; in general, their impact on historiography increased as the Middle Ages proceeded.


Both the academic and popular press have produced a spate of articles debating the role information technology played in fueling the economic expansion of the last decade. It was not all that long ago that many commentators claimed that the emergence of a "new economy" was responsible for the abolition of the business cycle. Shifting fortunes in the stock market and the threat of an economic slowdown however, have inspired increasing skepticism towards this view. Indeed, some observers now argue that the rapid diffusion of information technology has had little or no effect on the productivity growth responsible for increasing the size of the nation's economic pie nor likely will it in the future. As often is the case, the truth probably lies somewhere between these extreme views. Though the early euphoria clearly was unrealistic, recent analyses by skeptics have been too narrow in their assessment of the impact of information technology on economic growth. The dramatic acceleration of investment in computer and information technology over the last decade promises to have positive economic benefits that extend well into the future. Analyzing the economic ramifications of this transformation is important if policy makers are to make wise decisions.


The IEEE 1687 standard, which is commonly used for efficient access of on-chip instruments, could be exploited by an intruder and thus needs to be secured. One of the techniques to alleviate the vulnerability of 1687 network is to use a secure access protocol that is based on licensed access software, Chip ID and locking SIB. A licensed access software is generally used to gain control of the embedded instruments and use them as per requirement. In this paper, a successful attack using various machine learning algorithms has been instigated on secure access protocol scheme. It is demonstrated that machine learning algorithms have the potential of breaching the secure communication between the access software and the board and hence access the sensitive instruments. Furthermore, Random Forest significantly outperforms the other models in terms of breaking the security.


Considering the current environment of economic crisis and signs of financial exhaustion of the Spanish health system, it has been analyzed one of the most insistently proposed measure for economic sustainability: the copayment. It has been studied whether its implementation affects the bioethical principles, particularly equity, within the principle of social justice. A cause and effect relationship between the co-payment measure and equity damage has been found. However, it is clear that copayment can become an appropriate instrument for the financial sustainability of the health system. Furthermore, from our study it can be concluded that the Spanish national health system is not in bankrupt and that its financial difficulties can be solved without having to give up the social benefits of a public health model for the population. This health system has contributed-and will, sure, in future, continue to improving the health of the citizens of the country.


Background: In biological system, cells are considered as dynamic and complex structures likewise cellulardisintegration is also a complex process which occurs in a sequence. Therefore, these autolytic cellularchanges have been investigated by forensic pathologist in an attempt to find markers that may assist indetermining the time of death. In this study we attempt to analyse the efficacy of oral soft tissues specificallysalivary gland in concluding the time since death.Methodology: After obtaining approval from the human ethical committee, informed consent from therelative of the corpse and the investigating police officer, demographic information, as well as post mortemnumber was recorded. Submandibular Salivary Gland was collected for histopathological analysis duringroutine autopsy procedure. The specimens were fixed immediately in 10% formalin, processed, sectionedand stained with haematoxylin and eosin. The stained sections were evaluated under light microscope forhistopathological changes.Conclusion. The histopathological changes in the autopsied salivary gland tissue can be used as an adjuvantto estimate the post-mortem interval.


A 61-year-old woman with hypertension, osteoarthritis, and hyperlipidemia presented with anemia and elevated serum creatinine concentration. She described fatigue and weakness but denied fever, chills, cough, dyspnea, nausea, vomiting, or diarrhea. Review of systems was otherwise unremarkable. Medications included the following: losartan 100 mg daily, atorvastatin 20 mg daily, multi-vitamins, and occasional acetaminophen and ibuprofen. Blood pressure (BP) was 150/92 mmHg while examination was normal except for trace ankle edema. There was no rash, petechiae, or purpura. Laboratory data revealed the following: normal electrolytes, blood urea nitrogen 65 mg/dL, serum creatinine 5.6 mg/dL (baseline 1.1 mg/dL), serum calcium 10.9 mg/ dL, serum albumin 3.2 mg/dL, and total protein 7.8 mg/dL. Urinalysis consisted of specific gravity of 1.013, pH 5.5, trace protein and negative blood, leukocyte esterase, glucose and nitrite. Urine protein: creatinine ratio was 3300 mg/ mg (which were subsequently documented as lambda light chains (LCs) on urine immunoelectrophoresis). Urine sediment examination revealed numerous odd shaped crystals and crystalline casts (Figure 1). The patient was treated with intravenous lactated Ringer's solution with no improvement in serum creatinine, which increased to 7.3 mg/dL over the next 48 h. The patient underwent kidney biopsy, which demonstrated crystalline structures in the tubules (Figure 2(a)). Electron microscopy revealed crystalline structures within the tubular lumens (Figure 2(b)). Immunofluorescence study of the kidney tissue revealed lambda LC staining of the crystalline casts but no kappa LC staining. Based on these findings, serum free LCs were measured and showed extremely elevated levels of lambda LCs and a suppressed ratio. Bone marrow biopsy was undertaken and revealed 45% plasma cells consistent with multiple myeloma. The diagnosis of multiple myeloma with LC crystalline cast nephropathy was made. The patient was treated with bortezomib, dexamethasone, and cyclophosphamide with good response. Serum creatinine improved to 1.7 mg/dL over the next month. The patient was left with stage 3b chronic kidney disease.


The culture of Hinduism in Bali is very preserved and maintained by the Hindus in Bali to remain dignified. Dewata Nawa Sanga is one of the Hindu Religion Concept embraced by the Hindus in Bali. Dewata Nawa Sanga means nine deities as a manifestation of God in charge of guarding and controlling the nine wind direction. The application of Augmented Reality Dewata Nawa Sanga developed to increase the knowledge of Hindus in Bali about the concept of Dewata Nawa Sanga, through a learning medium considering the importance of Dewata Nawa Sanga for Hindus in Bali. The application of Augmented Reality Dewata Nawa Sanga developed using the markerless method, so users simply rotate the Android devices to see the position of Deity in the nine wind directions and to know the information of each of the deities. Application of Augmented Reality Dewata Nawa Sanga provides education about detail elements about each Deity in nine wind direction through Information View feature in narrative form. The resulting application indirectly educates the user to know the direction of the controlled and guarded by nine Deity as a manifestation of the god through Augmented Reality display by using gyroscope sensors.


The value of, and theoretical basis for, interdisciplinary approaches in paleosciences has been widely recognized (e.g. Dearing et al. 2011; Fischer et al. 2021). Meanwhile, it has also been realized that identifying feasible and inclusive strategies to put interdisciplinarity into practice requires continued community mobilization and collaboration (Swanson et al. 2021). Here, we bring an example of scientific community mobilization and collaboration focused on the Global South; the geographical region covering Latin America and the Caribbean, Africa, Asia, and parts of Oceania (Fig. 1), where researchers have been historically, and often continue to be, marginalized from international collaborations (Maas et al. 2021).


The analytical methodology utilized in our laboratory involved the simultaneous detection of all volatile organic compounds (VOCs), listed in the Drinking Water Regulations [10], by combining the Electrolytic Conductivity Detector (ELCD), outfitted with a 1.8 mm quartz reaction tube, in series with the photo-ionization detector (PID)


A generalized method for obtaining individual level population ratios is used to obtain relative intensities of extreme ultraviolet Fe XV emission lines in the range 284 --500 A, which are density dependent for electron densities in the tokamak regime or higher. Four lines in particular are found to attain quite high intensities in the high-density limit. The same calculation provides inelastic contributions to linewidths. The method connects level populations and level widths through total probabilities t/sub i/j, related to ''taboo'' probabilities of Markov chain theory. The t/sub i/j are here evaluated for a real atomic system, being therefore of potential interest to random-walk theorists who have been limited to idealized systems characterized by simplified transition schemes.


Based on an eco-model,we analyzed the monthly monitoring data of Lake Taihu from April 2009 to November 2010,and found that the growth rates of Lake Taihu cyanobacteria showed significant both temporal and spatial differences.The growth rates of cyanobacteria were low from January to April,and from October to December,while high level from June to September.But the growth rates in May showed annual difference.Furthermore,the growth rates in western lakeshore were higher than those in the central lake.The growth of cyanobacteria from surface water to one-meter depth was active.Growth of cyanobacteria was mainly controlled by water temperature,illumination and phosphorus concentration.These three limiting factors showed significant seasonal variation and interchanged with the others.In the surface water,temperature and phosphorus were the main limiting factors,while temperature,phosphorus and illumination at the depth of half a meter,and illumination below one-meter depth.The result showed that phosphorus concentration in summer and fall was the major limit on nutrient phosphorus,and also limit on nitrogen in some areas.

Background and Objective: Vitamin D plays a significant role in the regulation of immune responses, as low levels of vitamin D are associated with faster progression of HIV infection to the third stage of AIDS. Total lymphocyte count is an appropriate laboratory index for determining the progression of AIDS. The aim of this study was to investigate the effect of vitamin D on the total lymphocyte count (TLC) and white blood cells (WBC) count among patients with HIV/AIDS. Materials and Methods: This clinical trial was conducted with participation of 66 HIV/AIDS patients in the consultation center for behavioral problems in the city of Varamin in Tehran Province in Iran who were categorized into two groups including intervention and control and in three stages including before intervention, three and six months after intervention. The selection of the participants in both groups was randomized, and the information gathering was done through interviewing based on the study questionnaire. A 50,000-unit-vitamin D3-Pearl was administered monthly for the intervention group. Three and six months after the intervention, the TLC and WBC count were determined. Data were analyzed by using Independent T-Test. Data analysis was computed by using SPSS software version 20. P<0.05 was considered significant. Results: The mean (SD) age of intervention group was 36.9 (2.0) and control group 36.2 (2). Prior to intervention, no significant differences were observed in the mean (SD) TLC among the intervention group and control group: 2359.1 (166.8) vs. 2354 (151). However, three month after vitamin D administration, the mean (SD) TLC in the intervention group was significantly more than the control group: 2447 (167.1) vs. 2141 (110.1), P=0.01. Six month after administration, no significant differences were observed in the mean (SD) TLC among the intervention group and control group: 2402.6 (169.8) vs. 2045.5 (104), P=0.03. No significant differences were observed in the mean (SD) WBC count among the intervention group and control group prior to intervention, three months, and six months after intervention: 6099.6 (1943.5) vs. 6316.2 (1631.7), 6035.8 (1586.7) vs. 6158.4 (1486.8) and 6110.6 (1523.8) vs. 6305.1 (569.2) respectively, P=0.6. Conclusion: The study showed that TLC significantly increased three and six months after vitamin D administration among HIV/AIDS patients. Therefore, monthly intake of vitamin D supplement among these patients can be effective in maintaining their immune state. Ethical code: IR.SBMU.PHNS.REC.1397.085.

CCl4 acute liver injury model group,check group and rhubarb treatment group(high-,moderate-and Iow-dose) were used to investigate the effect of rhubarb on mice liver protein expression.Electrophoresis analysis revealed that rhubarb may cause liver protein expression change of mice.High-dose group presented new protein and increased protein content,and moderate and low dose group exhibited obvious change.CCl4 may cause transaminase increase and rhubarb decreased transaminase.Rhubarb can protect liver injury caused by CCl4.


The transition rate for thermal and epithermal positrons being trapped into the image‐potential‐induced state on a metal surface is discussed. We show that there is no analogue to the resonance trapping of epithermal positrons predicted for bulk vacancies and that the transition rate into the surface state goes to zero at 0 K. Our results are compared with recent experimental results on positron trapping at a clean Cu(110) surface and into large voids in Al and Cu, and also positron reemission at clean Cu(110) and Al(110) surfaces.


The purpose of this paper is to develop a simple dynamic model to analyze researchers' interest in answering questions for an online question and answer (Q&A) knowledge market. With use of a System Dynamics model, an online knowledge market can be modeled as a marketplace where consumers ask and researchers answer questions to make knowledge transactions. In this market, consumers price their questions to acquire answers, and a company maintains the online knowledge market by determining the optimal price allocation to researchers. This paper focuses on the design of a simple model based on Zhang & Jasimuddin's equation that represents the dynamics of researchers' interest in answering questions in a specific kind of online knowledge market. The model shows this behavior of researchers. Furthermore, implementation of this model results in generating new and useful insights about the policy option analysis for developing new strategies in same knowledge markets.


While Lady Wisdom, Zion and Jerusalem, for example, are well-known and frequently analyzed personifications in the Old Testament, the study of personifications in the book of psalms is a research desideratum. After presenting the theoretical background of the term personification with special focus on the function of the verb, I will present the results of verb personifications in the psalter followed by a textual analysis of the personified virtues of steadfast love, truth, justice and peace in Ps 85:11. One example of the encounter between justice and peace in the form of a kiss, from Christian reception history, forms the last part of the article. The paper aims to contribute to the broad and intense discussion of metaphor analysis in psalms research on the three levels of theory, of textual analysis of the whole book of psalms and of Ps 85,11 and the reception history of metaphors.


The effect of light quality, light intensity and photoperiod on stem elongation of chrysanthemum was studied using an image processing technique. The plant stem and internode elongation was higher in the dark than in the light, and the growth of chrysanthemum was promoted in dark period. The effect of light quality was more significant than that of light intensity and photoperiod on the growth of chrysanthemum. The growth of chrysanthemum was inhibited under blue light, and the relative elongation rate of internodes decreased with increasing intensity of blue light and irradiation duration. Chrysanthemum growth is regulated by the light condition during irradiation. This system is useful to build a model to describe the stem elongation relative to light condition for chrysanthemum, and to suggest effective production method with substitutes for chemical growth regulators.


ABSTRACT It is generally agreed that good subject knowledge is an important prerequisite for successful teaching. However, what constitutes good subject knowledge is debated, with multiple perspectives taken by policymakers, researchers and schools. This article reports on research into interpretations of 'understanding mathematics in depth' (UMID) of pre-service secondary mathematics teachers at an English university, some of whom had completed a Subject Knowledge Enhancement course prior to their teacher training programme. Qualitative data were drawn from semi-structured interviews with the teachers, and an in-depth case study of one of the sample. Analysis of data revealed that knowledge growth was located mostly within pedagogical content knowledge. UMID was articulated as 'knowing why' and 'being able to communicate'. Additionally, non-elicited themes emerged, relating to the way in which teachers' knowledge develops. Findings highlight relevant messages for policy and practice regarding the integration of subject matter knowledge and pedagogical content knowledge.


To wear comfortable stockings and make legs look beautiful are the attractive subjects for women of all ages. With the exception of summer season, almost all women wear hosiery: panty hoses, tights, knee-length socks and socks. In general, knitted fabric of hosiery has the advantage of being highly efficient at both stretching highly and fitting. In this study, a variety of women's hosiery ate examined for their performance both under no deformation and deformed condition during wearing. One of purposes of this study is to compare the performance of various hosieries objectively. The other of purposes is to estimate the change of the performance by wearing deformation for each sort of hosiery. Deformation is observed in wearing test and given an account of stretch ratio values for wale and course directions. Compression property is measured first. Standard thickness, compression work and resilience values are recorded from the pressure-thickness relation curves. And air resistance and thermal conductance are measured by KESAP1 and KESTHERMOLABO II fabric testing instruments, respectively. In addition, sensory tests are carried out to examine affective disposition of women who choose stockings to acquire better aesthetic and comfort. Tests are held with several items, for example, tactile impressions of softness, thickness and smoothness, and visual impressions of transparency and degree of compression. In the tests questionnaires are used and judges are young women.


Abstract We present version 1.0 of the McStas freeware program package for neutron simulations. The package is based upon a special meta-language designed for Monte Carlo ray-tracing calculations and includes a library of spectrometer components and visualization tools. A detailed simulation of the Rise triple-axis spectrometer TASl shows good agreement with experiments. We invite neutron researchers to use this package and to contribute to the development of the component library.


A new bipartisan proposal attempting to ?save? Medicare would impose a 3-year ban on further cuts to Medicare reimbursement to physicians. Other aspects of the plan make its future questionable, however. The proposal includes political landmines, such as raising the Medicare eligibility age and requiring more out-of-pocket payments from Medicare beneficiaries who can afford them.


Based on the Carnegie-Ames-Stanford approach(CASA)model,the temporal and spatial variations of vegetation NPP in northwest China during the period 2000—2013were analyzed by combining with geo-statistics theory and using trend and correlation analysis.Meanwhile,the relationships between vegetation NPP and climate change were also examined by using the meteorological data.The results showed that:(1)The vegetation NPP in northwest China presented the fluctuating increase trend which reached an extremely significant level (p<0.01);(2)The distribution of vegetation NPP had obvious spatial heterogeneity,which generaly presented the decreasing trend from east to west;Except for Xinjiang,the other provinces also showed the low state in the north;the area with increasing vegetation NPP accounted for 85.97% of the total area,and mainly distributed in northern Shaanxi,southern Ningxia,eastern Gansu,eastern and southern parts of Qinghai,and parts of western Xinjiang,while the NPP presented the decreasing trend in west of Xinjiang; The average NPP values of different vegetation types showed significant differences,and folowed an order of:grassland[262.16g C/(m·a)]>shrub[66.51g C/(m·a)]>farmland[45.90g C/(m·a)]>forest [14.36g C/(m·a)];The NPP of grassland,farmland,and shrub al showed the extremely significant increase(p<0.01),but the increase of forests was not obvious(p>0.05);(3)In general,vegetation NPP was positively correlated with temperature and precipitation,and was more sensitive to precipitation;Therefore,precipitation was the main factor limiting the increase of vegetation NPP in this area.

In dramatic, front-page news, Kent Brantly and Nancy Writebol, 2 American missionary workers infected with the deadly Ebola virus, were given a highly experimental combination of preformed monoclonal antibodies directed against the virus and previously shown to work only in monkeys. Brantly, moribund and poorly responsive to a previous blood transfusion containing convalescent antibodies, apparently began to recover within an hour of receiving the medication [and] was able to take a shower on his own before getting on a specially designed Gulfstream air ambulance jet to be evacuated to the United States (1). This is not the first time that passive serotherapy has been described as miraculous. These headlines hearken back to well over a century ago, decades before the advent of such miracle drugs as sulfonamides and antibiotics. Medical scientists and practitioners did not wait for such unknown drugs. Rather, if the 1870s and 1880s represented the golden age of microbiology, as Louis Pasteur and Robert Koch led in identifying the agents of anthrax, diphtheria, pneumonia, tuberculosis, and the like, then the 1880s and 1890s represented the advent of applied humoral immunology. By 1890, Emil von Behring and Shibasaburo Kitasato, working under Koch in Berlin, had identified humoral factors in exposed animals that when transferred into laboratory animals were protective against diphtheria and tetanus toxins. From the 1890s onward, this model of productionexpose an animal (such as guinea pig, rabbit, cow, or horse) to an identified microbial pathogen, generate antibodies (or use convalescent serum from former patients), and then passively transfer the preformed antibodies to an exposed animal or personcould be expanded to such feared and prevalent diseases as pneumococcal pneumonia and meningococcal meningitis. This was scientific medicine at its most precise. When Paul Ehrlich coined the term magic bullet in 1906, he was in fact referring to such precision antibodies, to which chemotherapy could only aspire (2). The antiserum treatment of pneumococcal pneumonia from the 1910s through the 1940s is perhaps the most instructive for our purposes (3). The Hospital of the Rockefeller Institute was opened in 1910 to serve as a model of bench-to-bedside medicine. Its first director, Rufus Cole, had gathered a team that included Osward Avery and demonstrated through case series of patients that if pneumococci were divided into serotypes, then type-specific antipneumococcal serotherapy could dramatically reduce deaths from certain key strains of the captain of the men of death. Cole planned to test the remedy in careful fashion among encamped soldiers gathering for World War I, but the chaos of the 1918 influenza epidemic threw such plans into disarray. The Metropolitan Life Insurance Company lost $23 million in excess death benefits during the epidemic. In response, it funded a series of studies at multiple institutionsBellevue Hospital, Boston City Hospital, and Harlem Hospitalto test the efficacy of the remedy by a method that went beyond the case study: controlled studies, in which every other patient (or patients on every other ward) received serotherapy, with results tabulated and statistically compared (and in some cases tested for statistical significance). Serotherapy was demonstrated to be effective against certain serotypes in the hospital setting, with once-moribund patients described as sitting in their beds reading the newspaper the following morning, reminiscent of Kent Brantly's recovery (4). Serotherapy was found most effective when administered early (again analogous to the treatment of Ebola, it seems), but most patients did not make it to the hospital in time to receive the remedy early in the course of the disease. In the setting of this apparent delivery gap, the Massachusetts State Board of Health originated the first pneumonia control program, through which pneumococcal typing stations and serum depot centers were established across the state, available to assist local practitioners so they could administer antiserum in the home. By the late 1930s, Surgeon General Thomas Parran declared a war on pneumonia, framing it around the notion of health as a fundamental right and the equitable distribution of the expensive and logistically complicated antiserum as a test of the advancement of the nation. Federal funding assisted the formation of pneumonia control programs in approximately two thirds of the states across the country. But with the advent of effective antipneumococcal sulfa drugs in the late 1930s and then penicillin during World War II, the pneumonia control programs collapsed entirely, as the antibiotic era gave rise to a new optimismsome would say antibiotic abandonand dreams of the conquest of all infectious disease (5). Antibiotics transformed the very practice of medicine, at the same time that they shaped the marketing and even the regulation of pharmaceuticals by the U.S. Food and Drug Administration more broadly from the 1950s onward (6, 7). By the late 1980s and early 1990s, however, in the wake of the AIDS epidemic, increasingly identified antibiotic resistance, public health retrenchment, and increasing globalization, such initial optimism had given way to fears regarding emerging infections and a world out of balance (8). Today, nearly half a century after the first evocation of a microbial superbug (9), we are surrounded by ever-escalating concerns regarding a postantibiotic era and emerging pathogens. We have long expected science to rescue us from microbial pathogens, and the monoclonal antibodies that seem to have cured Kent Brantly are indeed miracle cures. Monoclonal antibodies themselves were not created until decades after the collapse of the last pneumonia control program, and modern science may well redefine research into a host of antimicrobial remedies, including bacteriophage therapy, probiotics, and passive serotherapy, that have their origins in the preantibiotic era. However, we can draw still further lessons from the earlier era of passive serotherapy. How can we ensure that such new magic bullets get to patients who need them, when and where they need them? How can this be done in an equitable fashion? And who gets sick in the first place, and why? There is only so much we can ask of seemingly magic bullets alone (10).


The estimation problem of non-stationary parameter matrices is considered for bilinear discrete dynamic system in the case when for these unknown parameter matrices their 'attraction' points are known at any moment. Explicit and recurrent forms of representation are obtained for these parameter estimates of the least squares method with variable forgetting factor and least deviation norm from 'attraction' points under non-classical assumptions. The recurrent algorithm is also proposed for corresponding weighted residual sum of squares.

I engaged in a computer room software installation, maintenance and management work. Then I generalize some management experience and skills.


the status quo. Given the opportunities to teach and Abstract The empirical evidence surrounding innovative technology-enhanced-learning practices in K-12 education is at best patchy. This study seeks to address this problem by investigating innovative mobile learning pedagogies for school-aged learners, including the extent to which these approaches may be disruptive to traditional school structures and practices. It adopts a rigorous Systematic Literature Review (SLR) methodology to interrogate this phenomenon, with fifty-seven high quality articles published between 2010 and 2017 meeting the stringent selection criteria. Content and thematic analysis showed low to medium degrees of innovation in most studies, with only 3 articles showing radically innovative, disruptive mobile learning practices. Illustrative examples are discussed across this 'innovation spectrum' and the notion of feasible innovation is proposed in the context of mobile learning in schools. The findings have implications for educators interested in designing and enacting effective innovative mobile learning practices, and researchers interested in the nature of innovation in mobile pedagogies. bacteria and how it travels through their digestive systems. Students were often shown a scientific experiment in school - which they frequently filmed using their mobile devices - and were then tasked with devising and undertaking a similar but different experiment at home with the help of their parents, again incorporating the mobile device. Findings from the study indicated that students were more engaged and more able to conduct their own research. They used the mobile devices extensively to produce artefacts to demonstrate their scientific understanding and to share and reflect on these with other students. Students were more self directed than previously, especially in working to teach their own parents about different scientific concepts. Significantly, students were more collaborative and prepared to share their ideas and reflections with peers which altered the culture of science lessons.


Constitutively phosphorylated proteins in Human fetal liver (HFL) aged 16-24 wk of gestation were studied using a 2-DE step followed by western blotting detection and MS identification. We found 166 phosphorylated protein spots with quantitative information and identified 101 gene products. Of theses identified proteins, 57 contain phosphoserine, 49 contain phosphothreonine, 51 contain phosphotyrosine, and 64 were newly identified phosphorylated proteins. The possible phosphorylation sites were further predicted using Netphos, ScanProsite and Scansite programs and most proteins were predicted the same site by at least 2 programs. Integrating the functional categories, protein abundance and the degree of phosphorylation of these proteins, we found proteins related to carbohydrate, lipid and amino acid metabolism were highly expressed with also the high degree of all serine, threonine and tyrosine phosphorylation; proteins associated with hematopoiesis were relatively highly expressed but with a relatively low degree of phosphorylation at serine, threonine and tyrosine; the proteins for signal transduction; biosynthesis of secondary metabolites and those whose function were unknown were lowly expressed, but with the zhigh degree of phosphorylation and interestingly, serine was the main phosphorylated amino acid of signal transducers; threonine in enzymes of biosynthesis of secondary metabolites; and tyrosine in proteins with unknown function.

Superstitions are an inevitable product of associative learning, which manifest in endless ways and have been impacting human behaviour in spheres such as health, business, education and sports etc. Superstitions benefit individuals in the form of a coping strategy or as a defense mechanism; but are only healthy if used in moderation. Superstitions have been termed as an irrational belief, a flawed perception and still persist despite the level of technological advancements taking place. Mindfulness as a means to enhance perception is an intervention that is gaining popularity and recognition in the field of psychology. The purpose of this paper is to establish a link between superstitions and mindlessness, in order to propose mindfulness as an intervention in a formal educational setting to combat superstitions.


Congenital dislocation of the hip with arthrogryposis multiplex congenita is more difficult to treat than developmental dislocation of the hip by either nonsurgical or surgical means. We treated 5 patients (7hips) surgically from 1980 to 1995. The average age at the time of surgery was approximately 2 years, except for 1 patient who was operated on when aged 7 years. Four patients (6hips) were treated by open reduction (O. R.), derotation-varus osteotomy (D. V. O), and shelf operation or pelvic osteotomy. One patient (1hip) was treated by O. R. and D. V. O. Reduction was relatively successful in all patients, with no recurrence of dislocation. Range of motion of the hip could be maintained by aggressive and continuous motion exercise which was commenced 4 weeks after surgery with the removal of the hip spica cast.


Machine learning (ML) has become a powerful building block for modern services, scientific? endeavors and enterprise processes. The expensive computations required for training ML models often makes it desirable to run them ina distributed manner in shared computing environments (e.g., Amazon EC2, Microsoft Azure, in-house shared clusters). Shared computing environments introduce a number of challenges, including uncorrelated performance jitter, heterogeneous resources, transient resources and limited bandwidth. This dissertation demonstrates that, by structuring software frameworks and work distribution to exploit transient resources and address performance jitter and communication bandwidth limitations, we can improve the e?efficiency of training machine learning models.We support this assertion with three case study systems: FlexRR, Proteus, and PipeDream. FlexRR is a distributed machine learning training system that combines a flexible synchronization model with dynamic peer-to-peer reassignment of work among workers to address stragglers caused by performance jitter. FlexRR observes near ideal run-time, mitigating the adverse effects of stragglers observed in shared computing environments. Proteus is an agile elastic machine learning training system that uses tiers of reliability and intelligent resource management to efficiently utilize transient compute resources.Evaluations on AWS EC2 show that Proteus reduces cost by 85% relative to non-transient pricing, and by 43% relative to previous approaches, while simultaneously reducing runtimes by up to 37%. PipeDream is a distributed trainingsystem for deep neural networks (DNNs) that partitions ranges of DNN layers among machines and aggressively pipelines computation and communication. By reducing the amount of communication, and overlapping communicationand computation, PipeDream provides a 5x or more improvement in \time to accuracy" for training large DNN models.


During the last decade, several publications indicated the hazard of laser plume. The German part of the European joint project STILMED (Safety Technology in Laser Medicine) focused on the investigation of the constituents of laser plume in four research groups. These investigated the volatile fraction of the combustion products of thermal laser treatment of biological tissues, as well in vitro, as in the operating room during laser surgery. The plume was trapped in different reaction chambers and analyzed by gas chromatography and mass spectrometry and other spectroscopic methods. Also, the plume was examined for viral fragments by PCR after laser treatment of virus infected tissue.With some variation for different lasers and different tissues, the major fraction of laser plume is water (70%). Besides the vapour, there are about 13% particulate aerosols and 17% gases. The latter are composed of 91% CO2, each 2% CO, NH3 and HCN, and 3% volatile organic compounds (VOC). Some 290 chemical compounds were identified and about 40 compounds with unknown mass spectra were separated. The quantification of some important substances yielded (in μg per g of disintegrated liver tissue): toluene 10-200, styrene 1-10, benzaldehyde 1-5, benzylcyanide 1-5, cholesterol 5000-10000. These numbers demonstrate that by far most of the VOCs are molecules, physiologically present in cells. The fraction of polycyclic aromatic hydrocarbons (PAH) was found to be of minor significance. The discussion of hazards due to toxic substances is based on threshold values for single compounds. However, laser plume is an exotic mixture of very many compounds. The size distribution of the particulate matter (0.1 - 10 μm) showed that there is a hazard due to inhalation. The spacial distribution of viral particles caused by laser shots was evaluated. There are viral DNA fragments in laser plume, even in the size of complete oncogenes. However, this does not clearly indicate infectiousity. Nevertheless, the results indicate specific protection measures during laser surgery.During the last decade, several publications indicated the hazard of laser plume.

In this article, the finite-time consensus problem is investigated for a group of heterogeneous nonlinear multiagent systems with input delays. Different from the existing results, input delays are assumed to be nonidentical and time-varying. To overcome the difficulty of nonidentical input delays, a novel compensation mechanism is introduced. Moreover, in order to save communication resources, a distributed finite-time self-triggered observer is constructed. By employing the observer and the dynamic surface control strategy, the finite-time adaptive neural control protocol is proposed. It is proved that not only the followers' outputs can be synchronized with the leader in finite time, but also continuous communication among followers is avoided. Finally, two simulation examples are provided to illustrate the validity of the proposed control strategy.


This paper studies the effects of He atom on the spin-polarized electronic properties of nickel under pressures using ab initio pseudopotential plan-wave method. Under high pressures, the compound of NiHe0.25 can exist and heliumbubble can not create in Ni. A pressure-induced ferromagnetic to paramagnetic phase transition has been predicted in NiHe0.25 at about 218 GPa. It is found that under pressures, the magnetic property of Ni atoms is more strongly affected by He atom than by H atom and that the behaviour of He atom in Ni are completely different from that of H atom, like the bonding characteristics and the electron transfer.

Abstract: The number of catalytic subunits of purified bovine nucleus caudatus acetylcholinesterase (E.C. 22.214.171.124) has been determined by active site labelling with [3H]diisopropyl fluorophosphate ([3H]DFP). The 10.5 S, 16 S, and 20 S forms were estimated to contain two, four, and six active sites, respectively, per molecule. A 4.8 S form, which showed a weak amphiphile‐dependent activity behavior, was obtained by selective proteolytic digestion with pronase. The inability of the purified 4.8 S form to aggregate after detergent removal, and the molecular mass in the range of 130‐165 kD under nondenaturating conditions, indicate that this form is a dimeric form, lacking those hydrophobic regions responsible for aggregation.


A uniform and stable inorganic-organic nanocomposite containing single-walled carbon nanotubes(SWNTs) and dodecyl aldehyde(DA) was obtained by ultrasonication method.The dispersant was dropped on a glassy carbon electrode surface for dryness to get a modified electrode(SWNTs-DA/GCE).Then the amino modified single-stranded probe DNA was covalently immobilized on SWNTs-DA/GCE by a facile amine-aldehyde condensation reaction,from which a novel DNA electrochemical sensor was constructed.The layer-by-layer assembly process of the biosensor was characterized by cyclic voltammetry and electrochemical impedance spectroscopy using [Fe(CN)6]3-/4-ions as electroactive probes.The analytical performance of the biosensor was investigated through using methylene blue(MB) as the hybridization indicator,and the results showed that the peak currents of MB on the biosensor had a good linear relationship with logarithm values of the target DNA concentrations(lgCS2) in the range of 1.0×10-15-1.0×10-10 mol/L(r=0.998).Based on three times of the signal-to-noise ratio(S/N=3),the limit of detection was estimated to be 2.0×10-16 mol/L.The selectivity experiments further showed that the complementary sequences,three-base mismatched sequences and the non-complementary sequences could be well distinguished by the biosensor.


This study examined factors significantly associated with early sexual initiation in Chile. Data were obtained from a baseline survey among 4248 urban students aged 11-19 years in March 1994. The survey was conducted before a sex education and reproductive health services program was initiated. It was hypothesized that early first sexual intercourse (FSI) would be associated with family structure parental education academic performance peer group influences use of drugs and alcohol and attitudes toward sexuality and early parenthood. The instrument was based on one used to evaluate a sex education program in Baltimore Maryland. Bivariate analyses and analyses of five separate multivariate logistic models were performed. The findings confirm that the factors associated with initiation of FSI were the same in the US and Chile. The final reduced model revealed that the significant factors associated with increased odds of FSI for males were as follows: age attitudes about the type of relationship appropriate for sexual intercourse a perception of the ideal age of FSI their current relationship perception of peers sexual experience belief that early parenthood limits employment options and risk behaviors of ever having smoked or used marijuana. For women the significant factors predicting sexual initiation were the same in individual and final models for sexual attitudes and relationship variables. The attitudes toward early pregnancy and ever having smoked cigarettes became insignificant in the final model. Significant factors were similar among both sexes regardless of whether the context contained machismo or not.

Modern computers have found an array of applications in industries because they are portable and user-orientated. With their huge expense and the ability to give near 100 percent efficiency, utmost care has to be taken while using them in scathing applications. In such cases, factors like temperature, mechanical stress and environmental pollutants can critically affect the performance of these computing systems and may eventually lead to system breakdowns. This may severely compromise with production efficiency as well as safety of people in and around the plant. This work tries to address the problem concerned with the temperature control of the computing system. In the proposed system, an effective and a low-cost temperature sensor circuit has been designed and implemented to monitor the panel temperature in case the panel air conditioner undergoes failure. If the temperature of the panel rises above a predefined threshold, an alarm will be generated which will be displayed on the computer screens of the respective authorities via Ethernet connection.


The purpose of this project was to find the optimal design of a Stirling engine car by maximizing the car's performance. Series of experimental data of specifications and power of α-type and γ-type Stirling engine cars were collected,and theoretical calculations and Matlab software were used to get quantitative analysis of the impact on the output power of the stroke volume ratio,the dead volume ratio and the temperature ratio. The analysis of the data indicates that,the temperature ratio is the main factor affecting the output of Stirling engine power,the bigger the temperature ratio is,the greater the power. And there is an extreme point of stroke volume to get the maximum power output. By comparison,the α-type Stirling engine is more easily influenced by the dead volume ratio than the γ-type.And under the same conditions of specifications and the temperature ratio,the α-type Stirling engine can output more work than γ-type. The innovation of the article is the use of Matlab software,which makes it more intuitive to find the relationship between the factors and the output power,and provides guidance and reference to the design of pint-sized Stirling engine.

Context: The main goal of this study is to assess depression symptoms and resilience among students inMalaysia. This study administered The Beck Depression Inventory II (BDI-II) and Resilience Scale 14(RS-14) to 560 students from five secondary schools. Descriptive statistics were employed to calibrate thesymptoms of depression according to their severity. Meanwhile, independent sample t-tests and one-wayANOVA were employed to examine differences in gender, school locations and ethnicity on depression.Pearson correlation was used to examine the relationship between resilience and depression among students.Results showed that feeling guilty was the most severe depression symptoms followed by self-accusationand punishment. In contrast, weight loss and suicidal ideation were the two least endorsed symptoms ofdepression by the students. The study reported significant differences in the mean score of depressionbetween gender and no significant difference in the depression scores in terms of locations and ethnicity.The results also reported a low negative correlation between depression and resilience (r =-.219). Symptomsof guilt, self-accusation and punishment are common among depressed students who had lower resilience.


Objective: To understand the characteristics of the non-survival cases of acute myocardial infarction (AMI), so to enhance the effect of prevention and treatment. Methods: To compare and analyze non-survival and survival cases among 304 patients hospitalized in our hospital from 1992 to 2001, to compare mortality rate of different age groups, male and female mortality rate, the risk factors and infarction position, and analyze the cause and time of death. Results: Mortality rate increases with age. Female mortality rate is higher than that of male patients. The mortality rate is apparently higher among the patients with a history of old myocardial infarction (OMI), diabetes mellitus, or hyperlipemia. Mortality rate of front lateral wall myocardial infarction is the highest. Most of the non-survival patients died within one week of hospitalization. Conclusions: Seniority, front lateral wall myocardial infarction, history of diabetes mellitus, OMI and hyperlipemia are the high risk factors of AMI non-survival cases.
