In order to reveal the epidemic regularity of Huanglongbing( HLB) in different management approaches,different citrus production areas were selected between 2002 and 2012 to compare epidemic regularity of different types and control effects of different management approaches with plant incidence rate. All survey data in 11 years were used to build a mathematical model,and epidemic evolution and control effects were quantitatively analyzed. The results indicated that diffusion and prevalence of HLB generally increased linearly. In naturally growing citrus orchards without artificial control,the annual diseased plant rate was 11. 11%,and the epidemic diffusion model was y1= 12. 24x- 1. 382 8( n = 9,r = 0. 976 9**). Under general prevention and control conditions,the annual diseased plant rate was 4. 69%,the epidemic diffusion model was y2= 5. 449 8x- 1. 603 5( n = 11,r = 0. 974 9**),and the control effect was 43. 93%( 22. 93%-55. 04%).In citrus orchards with integrated prevention and control,the epidemic diffusion model was y**3= 0. 366 3x- 0. 342 2( n = 11,r = 0. 989 8),the control effect was 96. 15%( 94. 95%- 97. 40%),and the annual diseased plant rate was 0. 31%. Thus,HLB is preventable and controllable as long as integrated prevention and control work is implemented well.


THE publication in 1914 of a paper by Sir William Crookes proved the starting-point of a change in the attitude of the lay public towards protective glasses. Since that date, popular taste in regard to the proper enjoyment of leisure has developed along lines that call for, or appear to call for, some measure of protection for the eyes. The recreations of all classes and both sexes now include long walks, sun-bathing, winter sports, and Mediterranean cruises. Expeditions to the Sahara, exploration of the Arctic, and longdistance flying may almost be termed fashionable. The extended use of radiation in therapeutics, and, not least, constant and persuasive advertising are other factors which have stimulated an everincreasing demand. Glass manufacturers, particularly abroad, have not been slow to respond. The industry at the present time has attained to considerable proportions. It provides the prescribing surgeon with an embarrassingly rich selection of types, and circulates an extensive trade literature. The position, however, is far from satisfactory. The available literature, being very largely derived from manufacturers and agents, is anything but disinterested. The claims preferred for a particular glass as a rule bear little relation to coright.


The early stage of the COVID-19 epidemic happened to be the flu season Since some symptoms of influenza and COVID-19 are similar, symptomatic patients flocked to fever clinics and emergency departments Meanwhile, asymptomatic COVID-19 patients attending other departments in general hospitals made things worse Lack of knowledge of the pathogen, absence of awareness and short of personal protective equipment all posed threat to healthcare workers as well as other patients As SARS-CoV-2 can be spread via droplets, direct contacts and potentially aerosols, the indoor air environment of hospitals, especially fever clinics, must have strict measures to prevent hospital-acquired infection Thirty-two sensors were deployed in the Tsinghua University Affiliated Beijing Tsinghua Changgung Hospital (mentioned as Changgung Hospital hereinafter) from January 30, 2020, in order to monitor high-resolution real-time indoor environmental parameters at its fever clinic, isolation wards and other departments One sensor monitors and records CO2 concentration, PM2 5 mass concentration, relative humidity, temperature and illuminance every 5 minutes Six sensors were located at the fever clinic, where all patients with fever and/or other COVID-19 related symptoms firstly attended after arriving at the hospital The clinic has two parts, one for diagnosis and the other for quarantine Three sensors were placed in doctor's office, nursing station and waiting area in the diagnosis part, respectively Natural ventilation was chosen to dilute the environment, as the flowrate of outdoor airflow was abundant in Beijing's winter Atmospheric CO2 concentration surrounding Changgung Hospital was stable, and the rise of indoor CO2 concentration was caused by human exhalation During this pandemic, CO2 concentration can be regarded as an indicator of room ventilation condition and hospital congestion, if all the people in hospital were regarded as potential infector of SARS-CoV-2 According to the usage pattern of the fever clinic, the maximum number of patients in each functional area was set as 4 for doctor's office, 4 for nursing station and 11 for waiting area According to the ventilation regulation of infectious disease hospital, the air change rate at fever clinics should be at least 6 h-1 In addition, the outdoor CO2 concentration was assumed to be 400 ppm Based on these conditions, the upper limits of indoor CO2 concentration were 902, 864 and 867 ppm for doctor's office, nursing station and waiting area at the Changgung Hospital's fever clinic, respectively Indoor CO2 concentration exceeding these thresholds stands for poor ventilation or overcrowds Fortunately, this didn't happen during the monitoring period and indoor CO2 concentration didn't exceed 609-711 ppm In another word, natural ventilation was sufficient and effective in this specific case at the Changgung Hospital's fever clinic Moreover, together with environment disinfection and personal protective measures, good ventilation condition led to no COVID-19 hospital-acquired infection To conclude, this article introduced a real-time environmental monitoring campaign at the Changgung Hospital's fever clinic Similar methodology can help assess ventilation conditions and risk of hospital-acquired infection at the fever clinic during and after COVID-19 pandemic Once indoor CO2 concentration exceeds the set thresholds, areas with high infection risk can be identified rapidly and timely, so that prevention measures can be taken in time © 2021, Science Press All right reserved


A derivation has been given by Hartel which relates the angular distribution of multiple scatter to that of single scatter, as determined by the Mie theory. Hartel's result is used to generalize Thiessing's equations for a medium which both scatters and absorbs radiation. The result is similar to the two-parameter theories used by numerous other workers, the difference being that the formulation given here constitutes an a priori method which relates the multiple scattering characteristics to the single scatter problem, whose solution is well known. Reflectance properties are calculated by numerically solving the equations for two illustrative cases.


As technology advances, so does the quality of treatment offered to cancer patients. Proton therapy, and more specifically proton pencil beam scanning, is currently at the forefront of radiation therapy. Pencil beam scanning offers excellent tumor dose control as well as sur rounding organs at risk sparing. Current treatment planning, however, is performed on a static image acquired before treatment. Naturally, this is not a proper representation of the actual patient on a daily basis. Thus, there is a need for adaptive radiation therapy, such as read justing a given treatment plan based on the patient's daily setup or a moving tumor location. In order to perform adaptive treatment delivery, appropriate imaging as well as an extremely fast, yet accurate, dose computation engine is needed. GEANT4 Monte Carlo simulations were performed in order to assess the imaging capabili ties and limitations of a proton radiography detector, comparing them to conventional X-ray imaging. In parallel, a small form factor proton radiography system was designed based on available technologies. Thus, photonic bandgap fibers, a CMOS active pixel sensor, and Bi cron scintillating fibers were evaluated for proton imaging purposes. The requisites and limitations of treatment planning for proton pencil beam scanning were further defined, from the acquisition of the treatment planning software's beam model to the methodologies and treatment robustness. Based on this work, a simplified Monte Carlo al gorithm was designed and implemented on the CPU architecture. This computation engine, GMC, was validated against physical observables and then compared to the treatment plan ning software dose calculation, as well as a "full" Monte Carlo recomputation. Proton radiography showed poor spatial resolution but excellent density resolution when com pared to X-ray radiography. This density resolution can be of importance when attempting to perform tumor tracking. The lower imaging dose associated with proton radiography is also of interest, especially in pediatric patients. Moreover, the use of a unique beam's eye view could slightly improve the accuracy of treatment delivery. Photonic bangap fibers, as well as the specific CMOS active pixel sensor used in this work, did not yield promising results for proton imaging. Conversely, Bicron scintillating fibers proved to be suitable for the design of a proton radiography system, as both the individual particle's position and energy could be acquired. The treatment planning software's beam model is very simple, as compared to other modal ities. However, the planning stage presented a few limitations, such as a lack of robustness analysis and issues related to spot placement. It was shown that both of these issues could be addressed with the use of a fast, yet accurate, dose computation engine. GMC was suc cessfully implemented on the CPU architecture, and compared extremely well against actual pre-treatment QA measurements. The comparisons against the current algorithm of the treat ment planning software and the full Monte Carlo engine matched the expectations for such an algorithm. The complementing work on proton imaging and fast dose computation algorithm lays a solid foundation to materializing pencil beam scanning adaptive radiotherapy. Future work will fo cus on generating the necessary synergy between the two systems in order to implement the tools in the clinical setting.


We propose a novel approach to boosting weighted linear discriminant analysis (LDA) as a weak classifier. Combining Adaboost with LDA allows selecting the most relevant features for classification at each boosting iteration, thus benefiting from feature correlation. The advantages of this approach include the use of a smaller number of weak learners to achieve a low error rate, improved classification performance due to the robustness and stable nature of LDA, and computational efficiency. The performance of the proposed method was evaluated on artificial data and additionally on two popular independent data sets: the Iris Data Set and the Breast Cancer Wisconsin Diagnostic Data Set, both publicly available. Experimental results showed the superior accuracy of the proposed method over LDA and AdaBoost combined with other types of weak classifiers. The weighted LDA algorithm was proven to be equivalent to the traditional LDA in the case of uniform weight distributions.


The invention relates to the technical field of audio processing and discloses an audio/video recording method, an audio/video playing method and an electronic device. During recording of audio and/or video data, if a dotting marking action of a user is detected, a mark is inserted into the audio and/or video data according to a preset mode, and a position with the inserted mark is recorded; after recording of the audio and/or video data is completed, an audio file and/or a video file inserted with the mark and the position with the inserted mark are stored. During playing of the audio file and/or video file inserted with the mark, an audio/video playing progress bar is displayed and the mark on the playing progress bar is marked. During recording, the mark can be inserted conveniently by the dotting marking action; during audio/video playing or playback, important content can be positioned rapidly according to the mark, so that the audio/video playing or playback is rapider and more convenient and accurate.


Complex construction projects face a dilemma: perspectives and interests of clients and project managers may diverge and even be contradictive. This dilemma is especially manifest in the management of the performance benchmarks time, cost, scope and quality. Administrators hold to pre-established benchmarks, while project managers have an interest in relaxing them, in order to be able to realize the project. When these two contradictory interests are not reconsolidated, either the benchmarks are not met, or they will be traded off in an uncontrolled way, which even may lead to project failure. This management trap is best to be avoided when designing the contract between client and contractors and the drawing up of the terms of reference. Due to the complexity that characterizes a lot of public projects, this is not always possible. With RandstadRail as example, we will show in this paper what problems may occur in these situations and how they can be dealt with.


(SUPPLEMENTAL DOCUMENT was submitted with the abstract) Tellurium oxide (TeO2) based glasses are widely used in many applications such as fibre optic, waveguide devices and Raman gain, and are now being considered for use in optical waveguide amplifiers. The se materials exhibit excellent transmission in the visible and near IR wavelength range (up to 2.0 μm ), low phonon energy, and high rare-earth solubility. Siloxane polymer materials on the other hand, have remark able thermal, mechanical and optical properties and allow the fabrication of low-loss optical waveguides di r ctly on printed circuit boards. In recent years, various low-cost optical backplanes have been demonstrated using this t echnology.However, all polymer optical circuits used in such applications are currently passive, requir ing therefore amplification of the data signals in the electrical domain to extend the transmission distance beyond their attenua tion limit. The combination of the TeO2 and siloxane technologies can enable the formation of low-cost optical waveguide amplif iers that can be deployed in board-level communications. However, there are significant technical challenges associated with the integration of these two dissimilar materials mainly due to the differen c in their thermal expansion coefficients. In this paper therefore, we propose a new approach for incorporating erbium (Er )-doped tellurium-oxide glass nanoparticles into siloxane polymer thin films using femtosecond pulsed laser deposi tion (fs-PLD). . Erbium-doped sodium zinc tellurite (Er-TZN) nanoparticles (NPs) are embedded into siloxane polymer films spin-coated on silica substrates using fs-PLD at low temperatures (100 °C) and under two differ ent pulse energies. The surface morphology, and the compositional and structural characteristics of the samples fabr icated are evaluated using scanning and transmission electron microscopy (SEM and TEM), TEMenergy-dispersive X ay spectrometry, Xray diffraction (XRD), and Raman spectroscopy. Additionally, photoluminescence (PL) and lifetime measurements are carried out at 1534 nm at room temperature under a 980 nm laser diode excitation. The SE M results show that average particle size of the Er-TZN NPs incorporated into polymer layer decreases with decreasing fs-pulse laser energy, while the PL measurements reveal a full-width at half-maximum (FWHM) of about 39 nm. The res pectiv FHWM value obtained from the bulk glass is 51 nm. The obtained luminescence lifetime of the samples is in the range 3.52 to 4.18 ms, which is slightly lower than the value obtained from the bulk glass target of 4.37 ms.


ABSTRACT Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 regulates viral gene expression at the posttranscriptional level during viral lytic infection. To study its function in the context of the viral genome, we disrupted KSHV ORF57 in the KSHV genome by transposon-based mutagenesis. The insertion of the transposon into the ORF57 exon 2 region also interrupted the 3′ untranslated region of KSHV ORF56, which overlaps with the ORF57 coding region. The disrupted viral genome, Bac36-Δ57, did not express ORF57, ORF59, K8α, K8.1, or a higher level of polyadenylated nuclear RNA after butyrate induction and could not be induced to produce infectious viruses in the presence of valproic acid, a histone deacetylase inhibitor and a novel KSHV lytic cycle inducer. The ectopic expression of ORF57 partially complemented the replication deficiency of the disrupted KSHV genome and the expression of the lytic gene ORF59. The induced production of infectious virus particles from the disrupted KSHV genome was also substantially restored by the simultaneous expression of both ORF57 and ORF56; complementation by ORF57 alone only partially restored the production of virus, and expression of ORF56 alone showed no effect. Altogether, our data indicate that in the context of the viral genome, KSHV ORF57 is essential for ORF59, K8α, and K8.1 expression and infectious virus production.


Pediatric cancer is considered rare and accounts for approximately 2% of all cancers. Wilms tumor accounts for approximately 6% of all pediatric cancers and in turn is the most common malignant renal tumor in childhood. Most are diagnosed before 5 years of age, with an average age at the time of diagnosis between 3 and 5 years, it is not common in those over 7 years and is rare in adults.
More than 90% are unilateral, 2% have synchronous multifocal lesions and 7% are bilateral. When this entity affects both kidneys simultaneously they are called synchronous, and when it occurs in the contralateral organ some time after the initial diagnosis, it is called metachronic. This malignant neoplasm is formed at the expense of embryonic kidney debris. It originates from the primitive metanephric blastema, precursor of normal renal tissue, although histologically they may contain different tissue remains, such as skeletal muscle, cartilage and squamous epithelium.
The familiar presentation of Wilms' Tumor as a single entity is rare. Only 2% of cases have an affected relative and the predisposition to the tumor is segregated as an autosomal dominant trait. However, there are several syndromes associated with a predisposition to develop this tumor. Among them are the WAGR syndromes (Wilms tumor, Aniridia, genitourinary abnormalities and mental retardation), Denys-Drash (DDS), Beckwith-Wiedeman (BWS), Frasier, Simpson-Golabi-Behmel (SGBS) and Wilms family tumor.

Related to the agent dacarbazine, CB10-277 is converted in vivo to a monomethyl triazene form that alkylates DNA, resulting in inhibition of DNA replication and repair; in addition, this agent may act as a purine analogue, resulting in inhibition of DNA synthesis, and may interact with protein sulfhydryl groups.


Dear Editor, We would like to present a case of a young male patient with fulminant myocarditis and multi-organ failure treated in our intensive care unit. In the early phase of the treatment, we simultaneously applied mechanical circulatory support (MCS) devices, including veno-arterial extracorporeal membrane oxygenation (ECMO). The use of short-term MCS devices in fulminant myocarditis and in other forms of severe heart failure has increased in recent years [1]. The results of some clinical trials indicate that this mode of treatment, when applied in the early phase of cardiogenic shock, yields promising final results [2, 3]. A 27-year old, previously healthy man was admitted to the Emergency Department with dyspnea, chest pain, and arterial hypotension. He had been suffering from flu-like syndrome for a week prior to admission. Upon hospital arrival, his mean arterial pressure was 50 mm Hg, and the heart rate was 120 beats per minute. Transthoracic echocardiogram (TTE) revealed severe dysfunction of both ventricles with 15% left ventricular (LV) ejection fraction (EF), 8 cm s-1 velocity-time integral of the left ventricle outflow track (LVOT VTI), and 12 mm tricuspid annular plane systolic excursion (TAPSE). Laboratory tests showed troponin above 10000 ng L-1, CK MB of 75.52 ng L-1, and ProBNP of 16497 ng L-1. DOI: https://doi.org/10.5114/ait.2020.93233


Summary The kinetics, activation, pH dependence and inhibition of platelet aggregation induced by ADP were studied by recording the OD of stirred PRP from blood anticoagulated with acid-citrate-dextrose solution. There was a lag period between the addition of ADP and the initiation of aggregation. Addition of ADP in the absence of stirring or ionized calcium did not cause aggregation. When aggregation was subsequently initiated by stirring or the addition of CaCl2 there was no lag period. The steepest slope of the OD curve was used as the reaction velocity (V). It was affected by the concentration of calcium ions and was maximum at pH 8.0. When the ADP concentration was varied in the presence of different concentrations of ionized calcium, the overall kinetics revealed a series of rectangular hyperbola segments which did not pass through the origin. These observations led to the conclusion that the overall reaction can be depicted as a chain reaction: ADP interacts reversibly with platelets; when calcium is present these platelets become "sticky" and, when stirred, they aggregate. Kinetic studies of inhibition indicated that adenosine is a competitive inhibitor of ADP. The guanidino compounds tested were noncompetitive with respect to ADP but their inhibitory activity was counteracted by calcium.

In a graph $\Gamma=(V,E)$, we consider the closed neighbourhood of a subset of vertices and use this notion to deduce a Moore closure operator in $V.$ We also consider the closed twin equivalence relation which puts in relation two vertices when they have the same closed neighbourhood. Those notions are deeply explored when $\Gamma$ is the power graph associated with a finite group $G$. In that case, among the corresponding closed twin equivalence classes, we introduce the concepts of plain, compound and critical class. The study of critical classes, joined with the properties of the Moore closure operator, allows to correct a mistake in the proof of Theorem 2 in P. J. Cameron, The power graph of a finite group, II, Journal of Group Theory 13 (2010) and to deduce a simple algorithm to reconstruct the directed power graph of a finite group from its undirected counterpart, as asked in Question 2 in P. J. Cameron, Graphs defined on groups, International Journal of Group Theory, vol. 11 (2022).


Starting from the characteristics of the global supply chain network,we have analyzed the special position of the transnational enterprises in the global value chain as well as the cause for and severe consequence from the weakening or absence of their social responsibility.Then we propose that we should encourage the transnational enterprises in China to bear their social responsibility by improving the structure of the global supply chains structure,reinforcing the leadership of the transnational enterprises in fulfilling their social responsibility,and systematic regulation.


As optical lithography continues to extend into low-k1 regime, resolution of mask patterns continues to diminish. The limitation of 1.35 NA posed by water-based lithography has led to the application of various resolution enhancement techniques (RET), for example, use of strong phase-shifting masks, aggressive OPC and sub-resolution assist features, customized illuminators, etc. The adoption of these RET techniques combined with the requirements to detect even smaller defects on masks due to increasing MEEF, poses considerable challenges for a mask inspection engineer. Inspecting masks under their actinic-aerial image conditions would detect defects that are more likely to print under those exposure conditions. However, this also makes reviewing such defects in their low-contrast aerial images very challenging. On the other hand, inspecting masks under higher resolution inspection optics would allow for better viewing of defects post-inspection. However, such inspections generally would also detect many more defects, including printable and nuisance, thereby making it difficult to judge which are of real concern for printability on wafer. Often, an inspection engineer may choose to use Aerial and/or high resolution inspection modes depending on where in the process flow the mask is and the specific device-layer characteristics of the mask. Hence, a comprehensive approach is needed in handling defects both post-aerial and post-high resolution inspections. This analysis system is designed for the Applied Materials Aera™ mask inspection platform, all data reported was collected using the Aera.


We study the influence of cluster environment on the chemical evolution of spiral galaxies in the Pegasus I cluster. We determine the gas-phase heavy element abundances of six galaxies in Pegasus derived from H ii region spectra obtained from integral-field spectroscopy. These abundances are analyzed in the context of Virgo, whose spirals are known to show increasing interstellar metallicity as a function of H i deficiency. The galaxies in the Pegasus cluster, despite its lower density and velocity dispersion, also display gas loss due to interstellar-medium–intracluster-medium interaction, albeit to a lesser degree. Based on the abundances of three H i deficient spirals and two H i normal spirals, we observe a heavy element abundance offset of +0.13 ± 0.07 dex for the H i deficient galaxies. This abundance differential is consistent with the differential observed in Virgo for galaxies with a similar H i deficiency, and we observe a correlation between log (O/H) and the H i deficiency parameter DEF for the two clusters analyzed together. Our results suggest that similar environmental mechanisms are driving the heavy element enhancement in both clusters.


Semiconductors that are based on uranium dioxide (or other actinide compounds) appear possible and could offer significant improvements in performance as compared to conventional Si, Ge, and GaAs materials. The energy band gap (forbidden band gap) for uranium dioxide (UO 2 ) lies between Si and GaAs at the optimum of the band gap vs efficiency curve (1), indicating that one should be able to use uranium oxides to make very efficient solar cells, semiconductors, or other electronic device. The electrical conductivity of intrinsic UO 2 is approximately the same as GaAs (1). The dielectric constant of UO 2 (∼22) is nearly double that for Si (11.2) and GaAs (14.1) (2), perhaps making UO 2 better suited for integrated circuits than Si, Ge, and GaAs. The ceramic oxides of uranium (e.g., U 3 O 8 or UO 2 ) can withstand much higher operating temperatures (∼2600 K) than can Si or GaAs (<473 K). In addition, oxides are much more resistive to radiation damage, perhaps making uranium oxides more suitable for fabrication of devices used in special (e.g., space and military) applications. Thus, it appears that a new higher performance class of semiconductors are possible: uranium oxide-based semiconductors. This paper discusses the electronic properties of uranium dioxide and describes the potential performance advantages of uranium dioxide as compared to conventional semiconductor materials. The need for additional fundamental data is discussed. The results of fabricating and testing a uraniumbased diode will be presented if the test results are available in time. This work was conducted under the auspices of the U.S. Department of Energy's Depleted Uranium Uses Research and Development Program.


This paper proposes an approach for the evaluation of DASH-based video transmission from a server located in a Content Delivery Network (CDN) to multiple LTE users. The approach is based on utilizing an analytical model for the HTTP/TCP transmission in the wired/core link, and simulation traces for the packet transmission in the wireless/access link. The core and access link are separately considered by using the Wireless Transmission Control Protocol (WTCP) at the eNodeB, and three scheduling approaches are used for delivering the video packets in the access link. Therefore, in our proposed approach, we emulate DASH-based end-to-end video delivery and observe how the scheduling strategy affects the video streaming quality depending on the number of users in the system.


Spontaneous breaking of Lorentz invariance may take place in string theories, possibly endowing the photon with a mass. This leads to the breaking of the conformal symmetry of the electromagnetic action allowing for the generation within inflationary scenarios of magnetic fields over $Mpc$ scales. We show that the generated fields are consistent with amplification by the galactic dynamo processes and can be as large as to explain the observed galactic magnetic fields through the collapse of protogalactic clouds.

Interest in timberlines came first to me 33 years ago when, while cruising arouind Kodiak, opportunity was presented to observe the arctic edge of the great Pacific Forest of Sitka spruce which there gives place to the alder-grassland of the Aleutians. This was followed by repeated opportunities to study the transition from forest to tundra in five other trips to the region between 1915 and 1930. What I saw there was so contrary to my preconceptions and so significant that I felt it necessary to study other timberlines. Accordingly, the northern Rocky Mountains were investigated in 1934 and 1935, and during the last decade much study has been given to Mount Washingtoni in New Hampshire. On account of the long lapse of time during which these studies have been prosecuted, some of the material has been published. I am convinced, however, that the older studies constitute necessary background for an understanding of the new material which is now presented for the first time. The limits to which forests penetrate northward and upward in different parts of a continent are parts of a


Let $\mathbb{K}$ be a number field of degree $n$ over $\mathbb{Q}$. Let $\widehat{\mathbb{A}}$ be the set of integers of $\mathbb{K}$ which are primitive over $\mathbb{Q}$ and $I(\mathbb{K})$ be its index. Gunji and McQuillan defined the following integer $i(\mathbb{K})=\underset{\theta\in \widehat{\mathbb{A}}}{\text{lcm}}\;i(\theta)$, where $i(\theta)=\underset{x\in \mathbb{Z}}{\text{gcd}}\;F_\theta(x)$ and $F_\theta(x)$ is the characteristic polynomial of $\theta$ over $\mathbb{Q}$. We prove that if $p$ is a prime number less than or equal to $n$ then there exists a number field $\mathbb{K}$ of degree $n$ for which $p$ divides $i(\mathbb{K})$. We compute $i(\mathbb{K})$ for cubic fields. Also we determine $I(\mathbb{K})$ and $i(\mathbb{K})$ for families of simplest number fields of degree less than $7$. We give also answers to questions one and two in \cite{Kihel}. Furthermore, we give a counter example to Theorem 11 in \cite{Kihel} and we discuss their conjecture.

When applied for some tasks, such as payload handling, assemble, repairing, and so on, the two arms of a humanoid robot will form closed kinematic chain. It makes the motion planning and control for dual-arm coordination very complex and difficult. In this paper, we presented two types of resolved motion control methods for a humanoid robot during coordinated manipulation. They are respectively position-level and velocity-level resolved motion control method. For the former, the position-level trajectory of the payload is firstly planned. Then the desired pose (position and attitude) of the two arms are simultaneously determined by resolving the constraints on their end-effectors. For the latter, the velocity of the payload is planned. Then, the each end-effectors' velocities are resolved according to the constraints on the closed-chain system. The joint variables of each arm are then calculated using the inverse kinematics equations, at position-level or velocity-level corresponding to the two cases above. Finally, a dynamic modeling and simulation platform is established based on ADAMS. The proposed methods are verified by typical cases.

The reaction of hydroxide ion with bis-2, 4-dichlorophenylphosphate in presence of micelles of cationic, (cetyltrimethyl ammoniumbromidde). Since, the concentration of reactants at micellar surface is a major source of enhancement of rates of bimolecular reactions involving counterions. Therefore effect of added peroxyanions on the above reaction which is strongly catalysed by the micelles of cationic detergent has been extensively studied. For the convenience the micellar rate effects and added peroxyanions have been described under varied experimental conditions of cationic. Kinetic study of micellar catalysed hydrolysis of bis-2, 4-DCPP with different concentrations of [OH-] ion has been carried out at 40±0.5 0C in aqueous-dioxan mixture (20 : 8 v/v) in presence and absence of {[CTAB] [SLS] and [POEDE]} × 10-3 mol dm-3 in solutions of borate buffer pH 8.0, 9.0 and 10.0. It has been known much early about the importance of organic phosphate esters as phospholipids, complex lipids (i.e. fatty acid esters containing phosphours, nitrogen bases or sugars) which have been ascribed to sphereical, helical and folded laminr type micelles.1 The most popular types of paste, cream, shampoo are currently employing sodiumlaurylsulphate as the detergent and sodiumsterate as the opacifying cream foaming agent4 and the thicknening agents. Low molecular weight, catonic agents and detergent of the type have been used. A closely related use is, for the treatment of fungal infections in dermatology Cationic surface active agents appear to have same general order of toxicity towards fungi as towards bacteria. The anionic detergents have been found to be effective against gram positive bacteria. A 2% ointment of sodium lauryl sulphate has been used to promote healing of wounds and udnerlying tissues following festulas of stomach intenstine5 etc. The surface active agents are used in agriculture for two major purpose, the more important of the use in as an ingredient in wide variety of spraying compositions for combating inspects fungi and other enemies of plant life. The second use is in washing fruits and vegetables before marketing in order to remove hazardous spray residues. The residue left after removing mono-2,4-dichlorophenylphosphate at b6,120-140°C was washed several times with boiling distilled water and 0.2N NaOH solution to remove 2,4-dichlorophenylphosphate monoester, unreacted phosphorousoxy-trichloride and the phenol are finally digested in hot 0.5N NaOH solution. It was filtered and the filtrate acidified with dilute HC1 using phenolphthalein as an indicator. A white precipitate obtained was separated by filtration and made free from hydroxyl ions with repeated washings with boiling water. It was then dried at room temperature and recrystallised with absolute ethyl alcohol to give a white crystalline solid which was identified to be bis-2,4-chlorophenylphosphate by the following physical characteristics. (i) Melting Point (Observed) = 148 (ii) Theoretical percentage of 'P' = 8.17 (iii) Observed percentage of 'P' = 8.23 (iv) Aromatic ring = 3060cm


Abstract : Laboratory apparatus which stimulates the biting action of sharks has been designed and constructed, for the screening of candidate plastic materials. Baited samples were exposed to live sharks in both natural and captive environments. The most promising materials, such as polycarbonates and rigid polyvinyl chlorides, are hard and tough, yet flexible enough to spool on a reel of reasonable dimensions. Laboratory tests show that polycarbonate is capable of entrapping a tooth tip and causing it to fracture. Problems of embrittlement by low temperatures and by chemical attack remain to be solved. It has been shown that for maximum effectiveness, the armor must be kept free of tensile stress.


For the importance of communication between human and machine interface, it would be valuable to develop an implement which has the ability to recognize emotional states. In this paper, we proposed an approach which can deal with the daily dependence and personal dependence in the data of multiple subjects and samples. 30 features were extracted from the physiological signals of subject for three states of emotion. The physiological signals measured were: electrocardiogram (ECG), skin temperature (SKT) and galvanic skin response (GSR). After removing the daily dependence and personal dependence by the statistical technique of MANOVA, six machine learning methods including Bayesian network learning, naive Bayesian classification, SVM, decision tree of C4.5, Logistic model and K-nearest-neighbor (KNN) were implemented to differentiate the emotional states. The results showed that Logistic model gives the best classification accuracy and the statistical technique of MANOVA can significantly improve the performance of all six machine learning methods in emotion recognition system.


Dongping had 1 327 reported cases of hand,foot,and mouth disease in 2010,including 812 cases involving males and 515 involving females.Of all of the cases,1 171 involved a child under 5 years of age(88.24%).Most(894 children,67.37%) lived separately from their parents.Of all of the cases,430 involved kindergarteners and school-aged children(32.40%) while 3 cases involved adults.Peak incidence was in June and July.Cases were scattered,with cases occurring in 14 towns(neighborhoods) in Dongping.Diagnosis was confirmed in 113 cases;most cases were due to Coxsackie A16(52 cases,46.02%) although some were due to the EV71 virus(22 cases,19.47%).


Microscleres of criccalic Demospongiae are very common in the Late Jurassic basin facies of the Northern Limestone Alps as well as in the Malmian sponge reefs of the Swabian and Frankian Alb (Germany).Two types of these microscleres, which belong to the Microcriccorhabds, have been altered so strongly by diagenetic solution processes that in these scleres a new type of sclere architecture has been presumed. All stages of sedimentary to early diagenetic alteration could be studied and for the first time the internal architecture of these scleres has been recognized. The many small pustules to very small spines on the surface of the scleres are in connexion with the branching channels of the axial channel, which envelopes the organic filament. Each of the spines, even the smallest, forms the end of the branching channels, indicating that the formation of the ring structure of the criccalic microscleres was directly controlled by the branching axial filament and not by the Silicalemma.


The article is devoted to one of the main demographic challenges for Russia and China - population aging. In the first part of the work, the main trends in the transformation of the age structure are considered, and the conclusion is drawn about the heterogeneity of the demographic aging process in the studied countries. It was revealed that Russia, which entered the phase of population aging earlier than China, practically does not progress in terms of growth in survival rates and healthy life expectancy of the population, which is reflected in a noticeably lower rate of deepening of old age in the age structure. The aging process of the Chinese population is noticeably more balanced due to the absence of serious gender differences in mortality rates, as well as due to the significantly lower internal differentiation of regions. The second part of the article analyzes the existing and probable socio-economic risks caused by the aging of the age structure of the population of Russia and China. It has been determined that for both countries, the problem of intensive aging of the population is becoming one of the key ones. Even now, the BRICS countries (all of which, with the exception of Russia, have seen a significant increase in the share and size of the older generation) are showing a decline in economic growth. After the completion of the stage of implementation of the demographic dividend, these indicators may fall to extremely low values, which, under a certain scenario, may become a catalyst for the emergence of a new planetary economic crisis, given the contribution of the BRICS countries to the world economy (especially China). Overcoming the negative consequences of the phenomenon of population aging is possible only with the development of a systematic policy for maintaining sustainable socio-economic development in new demographic conditions


Recent progress in the efficient computation of discretized multi-dimensional operators and functions by tensor product operations allows to reconsider some bottleneck problems in the computational quantum chemistry. In this paper we present the tensorstructured technique for fast and accurate ab initio evaluation of the exchange Galerkin matrix in the Hartree-Fock equation. The core of our approach is the tensor representation of all involved functions and operators on 3D Cartesian grid, and implementation of the corresponding algebraic operations in the tensor product format. Due to linear scaling of tensor operations with respect to the one-dimension grid size we achieve the desired high accuracy of computations on huge 3D Cartesian grids up to size 163843. Contrary to conventional methods, the proposed computational scheme is neither restricted to the obligatory "analytically separable" rank-1 basis sets like Gaussians, nor to problem independent bases like plane waves. Along with the recent tensorstructured algorithms for the evaluation of the Coulomb matrix, efficient tensor product approximation of the exchange operator pioneers the way to the numerical solution of the Hartree-Fock equation on 3D Cartesian grid in a tensor-structured format.

High‐Tc Josephson junctions have been fabricated by direct electron beam writing over YBa2Cu3O7 thin‐film microbridges, using scanning transmission electron microscope (STEM) with an accelerating voltage of 80–120 kV. Annealing at 330–380 K increases Tc and Ic of the junctions and makes them more stable. In the operating range of a few degrees below Tc, the junctions show 100% magnetic field modulation of the critical current, microwave‐induced Shapiro steps oscillating according to the resistively shunted junction (RSJ) model, and RSJ current‐voltage characteristics with IcRn product up to 0.5–0.6 mV at 75 K and 0.3 mV at 77 K.


In 1929 Morquio described an osseous dystrophy in a family, in which four out of five siblings were affected. In 1931 Brailsford described the radiological features of the disease. Since then about 40 additional cases have been reported in subjects all of European descent. Of the four cases presented in this paper, two are pure Africans and two are of mixed European-African racial origin. Little is known about the aetiology or pathology of the disease except that many of the cases show a familial and hereditary tendency, but in some instances only a single member of a family has been affected. Shelling (1947) is of the opinion that a dominant Mendelian factor is involved as in achondroplasia, but in the family described by Jacobsen (1939) 20 members belonging to five generations were affected; the hereditary trait appeared to be a sex-linked recessive character. Consanguinity of parents and paternal grandparents was reported by Morquio, but this has not been a feature of all the cases described. In three of our cases a history of consanguineous parents was obtained. Case Reports Cases 1 and 2. The subjects reported here are both female siblings (Fig. 1). They are the eldest (7 years) and the youngest (1 year 2 months) of three sisters. The unaffected sibling, aged 3 years, is apparently normal in every respect and shows no radiological changes in the skeleton. Both the affected children were full term normal infants at birth, were breast fed, and sat up, crawled, and walked at the normal age. In both, the mother noticed that from about the age of I year they had difficulty in breathing because of ' blocked noses.' The mother is of pure Bantu stock but the father is coloured (mixed). The parents' mothers were first cousins. Neither can recall any deformity in members of their respective families. Both parents are healthy. Before the birth of the first child the mother had a premature labour at 32 weeks. During her subsequent pregnancies she enjoyed good health and her deliveries were all normal. CASE 1. T.M., a girl aged 7 years, sat up at 6j months, crawled at 7 months, and walked before the age of a year. 279 At the age of 3 years the mother noticed that the child was ' knock-kneed and had swelling of her wrists'. She had always had a blocked nose and nasal discharge. At the age of 4 years her tonsils were removed. Examination revealed a well nourished, intelligent, and cooperative child. The head appeared large, the circumference 21 in. (normal 20j in.). The hair was dry and wiry, the eyelashes long and curled, the nose broad and flattened at the base. The external nares were filled with thick discharge. The enamel of the


In a multiagent system (MAS), agents can have different opinions about a given problem. In order to solve the problem collectively they have to reach consensus about the ontology of the problem. A solution to probabilistic reasoning in such an environment by using a social network of trust is given. It is shown that frame logic can be annotated and amalgamated by using this approach which gives a foundation for collective ontology development in MAS. Consider the following problem: a set of agents in a multiagent system (MAS) model a certain domain in order to collectively solve a problem. Their opinions about the domain differ in various ways. The agents are connected into a social network defined by trust relations. The problem to be solved is how to obtain consensus about the domain.


The firing of weapons or demolitions for training purposes normally takes place at dedicated sites. Commonly used, pre-defined training scenarios result in repetitive blast emissions. In many cases, these emissions are dominated by reflections of the blast sound from surfaces close to the weapon or from obstacles that are present at the site during firing. The ground is one of these reflecting surfaces. As a consequence, sound at receiving sites can be dominated by the reflected sound at the source. Therefore, noise abatement measures applied to reflecting surfaces close to the muzzle of a gun or close to a demolition can very effectively reduce the sound at receiver sites. Close to a blast source, the acoustical levels are very high and the rules of linear acoustics do not necessarily apply for absorption phenomena. In order to develop noise abatement measures close to a blast source, tests were conducted using small demolitions (50 g) and muzzle blasts of a pistol shooting blanks. This paper reports on tests that investigated the use of mineral and steel wool for blast sound absorption. One major result is that the benefits of absorbing materials near to the source are limited by the significant reflections of the blast at the surface of the absorbing material. To reduce this effect, a pile of layered absorbers was tested with the density gradually increasing from layer to layer.


The current outbreak of Ebola virus in the Democratic Republic of the Congo is a reminder that dangerous diseases exist in many corners of the world and that they can cause substantial human suffering and financial devastation locally and internationally. In response, institutions and nations are constructing maximum biocontainment laboratories (MCLs) to address these threats. MCLs operate at the highest level of biological containment to diagnose, perform research on, and validate cures for life-threatening diseases like Ebola. There are more than 50 MCLs that are operational, under construction, or in advanced planning around the world. The global proliferation of these facilities raises questions about how to ensure their safe and secure operations while enhancing their contributions to science and global health. One solution is to establish an MCL network that enables the sharing of best practices, collaboration, transparency, and exchange of specimens and technology.


Efficient homomorphic encryption enables the construction of an encrypted computer system. Previous work has shown how this can be achieved using only arithmetic representations of simple demultiplexer circuits. This poster extends the results by introducing a caching mechanism for oblivious memory access, by far the most time-consuming building block of a recently proposed sample machine architecture. The construction allows to significantly accelerate homomorphically encrypted machine operation while still preserving obliviousness of memory access, control unit operation and functional components.


This paper presents a new method for measuring tar concentration in biomass-derived producer gas streams. This solvent-free method is much simpler than the evaporative method of the International Energy Agency (IEA) tar protocol. In tests on producer gas from a fluidized bed biomass gasifier this so-called dry condenser method yielded tar measurements with precision better than 5% and accuracy averaging to within 10% of the IEA tar protocol. Comparisons of water vapor concentrations in producer gas as determined by the two methodologies showed poor agreement, which appears to be due to the low precision of both techniques for this measurement, possibly the result of dissolved hydrocarbons in the recovered aqueous phases.

Leukocytes of cattle, sheep and swine can be quickly and easily isolated from heparinized whole blood using a 6% Ficoll–10% Hypaque gradient system. The leukocytes isolated using this method are easily cultured in a routine manner for chromosome preparation. It was found that both good quality and quantity of metaphase spreads can be consistently obtained from all the animals examined. This simple technique will facilitate cytogenetic screening programs in the bovine and swine where chromosome abnormalities seem to be associated with reproductive performance.


This article first examines the historical conditions surrounding the evolution of royal commissions of inquiry, and the political and ideological functions that they may serve. The royal commissions of inquiry established in Australia during the 1970s and 1980s to inquire into organised crime are discussed in order to explore possibilities for a general explanation of royal commissions.The conclusion reached is that royal commissions of inquiry are an important component of official discourse and may perform a legitimation function for apparatuses of the state. However, royal commissions of inquiry are too diverse in their effects to be tied down to a uniform explanatory model, whether based upon notions of crisis motivation or legitimation deficit.


The mission objective of STEP Cube Lab. (Cube Laboratory for Space Technology Experimental Project) classified as a pico-class satellite is to verify the technical effectiveness of payloads such as variable emittance radiator, SMA washer, oscillating heat pipe and MEMS based solid propellant thruster researched at domestic universities. In addition, the MEMS concentrating photovoltaic power system and the non-explosive holding and separation mechanism with the advantages of high constraint force and low shock level will be developed as the primary payloads for on-orbit verification. In this study, the feasibility of the mission actualization has been confirmed by the preliminary system design.


In this paper, a quantum Stern-Gerlach thought experiment is introduced where, in addition to the intrinsic angular momentum of an atom, the magnetic field is also treated quantum mechanically. A freely falling spin polarised Bose-Einstein condensate passes close to a flux-qubit and interacts with the quantum superimposed magnetic field of the flux-qubit. Such an interaction results a macroscopic quantum entanglement of the path of a Bose-Einstein condensate with the magnetic flux quantum state of the flux-qubit. In this paper, three regimes of coupling between the flux-qubit and a freely falling Bose-Einstein condensate are discussed. The decoherence time limit required to achieve a strong coupling regime is also estimated. This paper also explores, how to produce a path entangled Bose-Einstein condensate where, the condensate can be located at physically distinct locations simultaneously. Paper provides new fundamental insights about the foundations of the quantum Stern-Gerlach experiment.

Introduction: Breastfeeding exclusively as food provide a nutritional, immunological and emotional needs for growth and development of children during the first six months of life and it has been associated with a reduction in infant mortality and morbidity from infectious diseases. Objective: Determine whether there is difference between the percentage of abandonment of exclusive breastfeeding in cardiac patients and healthy children under 24 months of age, the causes of abandonment of breastfeeding and whether a difference exist between the time of abandonment in healthy children and children with heart disease. Material and methods: This is a retrospective study of two cohorts of children attending the outpatient Pediatric Cardiology and Pediatrics at the Hospital para el Nino, Instituto Materno Infantil del Estado de Mexico through a nonrandom sample of 100 patients with heart disease and 100 healthy children under two years of age, in which we applied a questionnaire to mothers of both groups to determine the time of exclusive breastfeeding for the first two years of life. Statistical analysis was performed using measures of central tendency and dispersion, we calculated a survival curve according to Kaplan-Meier method using as determining the abandonment of exclusive breastfeeding. Results: We included a total of 178 patients (78 cardiac patients and 100 healthy), based on the fulfillment of the inclusion criteria. The main cause of abandonment as the main cause in patients with heart disease by the child's illness (32%), whereas in healthy patients the main cause is due to insufficient milk (36%). The average time of exclusive breastfeeding was first 18.5% of those who never received womb, in the group of patients with heart disease correlates with the absence of breastfeeding (25%) of 16 close % in healthy patients who received


The water-soluble tetra-, hexa- and octasulfonated calix[4]arenes, calix[6]arenes, and calix[8]arenes 1–3, respectively, were investigated as potential synthetic receptors for photolabile cholinergic ligand A, a photolytic precursor of choline. Ligand A is a bifunctional molecule carrying a photolabile 2-nitrobenzyl group at one end and a choline moiety at the other end. Results from NMR studies have shown that calixarenes 1–3 form stable 1 : 1 complexes with A, having similar binding potential to that observed with the cholinergic enzymes acetylcholinesterase and butyrylcholinesterase. Further studies have suggested that calix[8]arene forms a ditopic complex by binding concomitantly to both the cationic choline moiety and the aromatic photolabile group of A, whereas calix[4]arene and calix[6]arene form monotopic complexes with A. The ditopic complex between calix[8]arene and A results from mutually induced fitting process, while the monotopic complexes between calix[4]arene and A can be regulated by pH: at neutral pH, calix[4]arene specifically binds the cationic choline moiety, while, at acidic pH, it complexes unselectively both the cationic choline moiety and the aromatic group of A. Our results show that para-sulfonated calixarenes are versatile artificial receptors which bind in various ways to the bifunctional photolabile cholinergic ligand A, depending on their size, geometry, and state of protonation.


Combing with the evolution and advances in the data quality and reliability research in RFID network, this paper classifies and analyzes various technologies for improving RFID data reliability and quality, including smoothing and arbitration, pipeline, estimation-based method, integrality-based restraint method, etc. When designing RFID system with high quality for meeting with several requirements, some current data cleaning technologies are properly chosen and fitted together adaptively to improve RFID reading reliability. 【


The pragmatic texture of second-person calls such as requesting, ordering, inviting, and entreating is complex. None of these speech acts are interchangeable. All are appropriate in some contexts and inappropriate in others, and all can be enabled or precluded by specific power relations. We argue that one cannot understand either the origin or the structure of many of our ethically significant normative statuses and relationships without attending to how they are instituted and modified by calls and the uptake they receive. Our model also enables us to give a close analysis of various forms of defiance and transgression.

Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. In this paper, we develop the Canny edge detector, introduce wavelet basis functions of nth Gaussian derivative and utilize them to extract the edge. At first, the principle of the edge detection by the wavelet transform is given briefly and new basis of wavelet functions are introduced and admissibility conditions of them are discussed. Then, the theoretical edge detection analysis of three significant edge types (step, ramp and stage) via new wavelet basis functions is studied, and relevant formulas are derived. The theory of the step response in the x, y and arbitrary direction is given and the effect of smoothing filter is obtained. We show that all introduced wavelet functions can detect the breakpoint of the step function. A model of the ramp function is presented and an approximation of it is used to simplify the results


The City of Tacoma has undertaken the task of reviving the Thea Foss Waterway, a 1.5-mile-long inlet along the downtown waterfront. Once the economic center of the city's maritime and industrial activities, the waterway had experienced a steady decline with tenants vacating properties leaving behind empty facilities and contaminated land. In 1981, the Federal Environmental Protection Agency declared the waterway as part of the Commencement Bay Nearshore/Tideflats Superfund Cleanup Project. The City subsequently mobilized support for recovering the waterway, culminating in the Thea Foss and Wheeler-Osgood Waterways Remediation Project, which commenced in November 2002. The project included dredging, capping, channel deepening, bank stabilization, creation of environmental habitat areas, and construction of an 11-acre capped Confined Disposal Facility, creating an equal amount of new industrial land.


1. Applications Short spiral baffles of a type described below were used successfully in the Molecular Beams Laboratory (RLE) with oil and mercury diffusion pumps and as liquid-nitrogen-cooled radiation shields for liquid-helium traps. This type of baffle can also be used to stop stray ions from entering ionization gauge tubes by placing it in the gauge tubulation, as shown in Fig. XXI-1. It also acts as a waveguide beyond cutoff for preventing stray rf fields from entering the vacuum system. With these corrugated baffles many turns can be made easily and quickly within a short length, whereas flat metal spirals cannot be formed closely without difficult and lengthy machining.


A nurse at the Liverpool City Hospital, Grafton Street, aged 29, after three months' typhoid work, was transferred to night duty in the scarlet fever wards. On October 31st, 1908eleven days later-she complained of not feeling well, and was therefore taken off duty. Indefinite symptoms characterized the onset of the illness up to November 5th, when the probability of enteric fever arose, and this was the provisional diagnosis till November 13th. It is sufficient to state that, though the classic signs were not prominent, the weight of evidence was in favour of enteric. Pyrexia was fairly typical, there were two doubtful spots, the spleen was palpable, and Ehrlich's diazo-reaction was positive. At 8 p.m. on November 13th-probably the fourteeth day of the disease-the patient had the first of a series of severe rigors, which recurred -at intervals during the next nine days, giving an unusual clinical picture in typhoid. The rigors lasted from twenty minutes to half an hour, and were followed, as a rule, by a profuse perspiration (see Chart). As the symptoms were associated with the development of a marked apical systolic bruit, and accentuation of the pulmonary second sound, and as on November 9th the GriinbaumWidal reaction was negative, it was thought that the case might be one of infective endocarditis simulating typhoid at its onset. On November 18th, therefore, a bacteriological examination of the blood was undertaken. The skin of the arm was sterilized; 10 c.cm. of blood were withdrawn from the median cephalic vein, and distributed among three flasks containing 100 c.cm. of broth and half a dozen slant -agar tubes. After forty-eight hours the flasks contained staphylococci, and a Gramnegative motile bacillus with many flagella. This bacillus, after it had been subeultured for several weeks, was agglutinated markedly in half an hour with the serum of a convalescent typhoid patient in dilutions of 1 in 15, 1 in 30, and 1 in 60, but not with normal serum. The bacillus also behaved in a manner characteristic of typhoid in glucose, lactose, cane sugar and mannite broths, litmus milk, gelatine, and broth. All the slant agar tubes, each of which contained only a few drops of blood, were covered with colonies of Staphylococcuts aureuts and albus, in about equal proportion, but the colonies were too numerous to count satisfactorily. No typhoid-like colonies were visible. Streptococci were absent in all the cultures. The bacteriological diagnosis of typhoid was further confirmed by the fact that, although on November 9th the Griinbaum-


Abstract This paper examined issues surrounding coal waste and its potential impacts on residential private wells by reviewing the existing literature to identify the possible issues and parameters associated with coal waste and its possible effects on private wells. Using well water data from the Big Sandy Region of Kentucky and West Virginia (n = 42), drinking water quality was examined using standard heavy metal parameters associated with coal waste: arsenic, cadmium, chromium, iron, lead, manganese, zinc, and sulfate. Findings showed significantly more wells in sub-watersheds with coal waste impoundments with iron levels above secondary drinking water standards. A review of similar wells from the Kentucky Groundwater Database Repository showed a similar trend. This pattern warranted further study of Fe as a possible coal slurry waste marker. Other general findings revealed high concentrations of manganese, lead, and arsenic across our sampling of cases. Levels of these metals were high in Appalachian rock, so linking their levels to coal mining is problematic. Overall, findings suggested that residential well water in the coal mining area of the Big Sandy region of Appalachia may be of variable and sometimes unhealthy quality.


The integration between curriculum and multicultural awareness is one of the solutions to create a good education. This article aims to review the development of a multicultural-based curriculum in Indonesia. This research uses a literature review system method. Data collection uses the help of Google Scholar (2019-2022) to search for articles relevant to developing a multicultural-based Islamic religious education curriculum. Based on the results of the literature review analysis, it can be concluded that in developing a multicultural-based curriculum, the points that need to be considered are: 1) The curriculum must pay attention to clear objectives following current conditions. 2) The curriculum must pay attention to relevant development models. 3) The curriculum must be based on the principles of curriculum development in Indonesia. 4) The development of a multicultural-based curriculum must have characteristics that include multicultural values of understanding and awareness.


British research on social movements, with a few exceptions, has been criticised for making little reference to social movement theory, such that the term, social movement is often used as an unproblematic descriptor. This failure leaves intact assumptions about the relationship between the aims, organisation and activity of social movements and the `interests' that underlie them. This paper attempts to integrate theoretical and substantive analyses of social movements in the context of the `two women's movements' in the United States and Britain which have had the family as a key focus for mobilisation: one conventionally associated with feminism, the other a mass movement of women mobilised to challenge feminism's claim to speak on their behalf. The analysis reveals the limitations of both mainstream and radical/Marxist explanations of social movements on account of their shared reductionist orientation. It suggests that a more fruitful account is provided by resource mobilisation and post-Marxist theorists who, despite drawing on different traditions and questions, recognise the autonomy of politicised culture. The article concludes by questioning whether any foundationalist notion of `interests' and the associated concept of `identity' can provide the basis for grounding political behaviour.


Wenyu River was mainly supplied by the non-conventional water sources such as effluent of wastewater treatment plants (WWTPs), thus suffered by severe ammonia nitrogen pollution. In order to quantitatively evaluate the performance of restoration programs in Wenyu River, QUAL2K model and scenario analysis were employed for water quality improvement simulation. Results showed that increasing both practical treatment capacity and discharge standards of WWTPs in the watershed of Wenyu River would be the most effective ways to improve the Wenyu River water quality, which could decrease ammonia nitrogen concentration by 29.66% at Beiguan Dam. Construction of bypass and off-line river purification systems in Wenyu River could reduce ammonia nitrogen concentration by 5.57% at Beiguan Dam. A comprehensive plan including upstream water quality improvement, sewage interception, pollution control of sidestreams, upgrade of WWTPs, and construction of bypass off-line river purification system, could reduce the ammonia nitrogen in the whole Wenyu River below the Class V surface water standard of China (GB3838—2002).


Background: The right lung is known to exhibit variations regarding the presence of fissures and lobes. Often the anomalies pertaining to the lungs remain undetected if they are asymptomatic. The variations may be detected incidentally in routine autopsies and cadaveric dissections. Methods: We studied thirty five cadaveric right lungs (n=35) to detect any anomalies pertaining to fissures and lobes. Results: Out of thirty five specimens studied, anomalous fissure and lobe was detected in a single lung specimen. The anomalous lung exhibited a single oblique fissure which did not extend to the inferior border, rather it extended to the anterior border of the right lung. The presence of the single oblique fissure resulted in formation of two lobes in the right lung. for performing lobectomies.

We present the first measurement of pion source radii in Pb–Pb collisions at the Large Hadron Collider. The radii were obtained by analyzing the Bose–Einstein enhancement in two-pion correlation functions. Like at lower energies, the radii drop with increasing transverse momentum, indicating the presence of collective expansion. In absolute terms, all three radii (Rout, Rside, Rlong) are larger than at RHIC, roughly consistent with a linear scaling with the cube root of the particle multiplicity.

Hypothesis generation is considered to be critical to the effectiveness and efficiency of diagnostic processes in auditing. Using a between‐subjects experimental design, this work examines the impact of fraud risk and the availability of a non‐misstatement management explanation on auditors' hypothesis generation performance. The context is when managers undertake analytical procedures at the planning stage of the audit. The results indicate that auditors are sensitive to increased fraud risk by generating more fraud hypotheses, while the number of misstatement hypotheses generated is not affected by fraud risk. The availability of a non‐misstatement management explanation was found not to interfere with auditors' hypothesis generation performance, but facilitated the generation of proportionately more misstatement and fraud hypotheses from the same transaction cycle as that indicated by the management explanation. Together, these findings provide some insights on the sensitivity of auditors' hypothesis generation to fraud risk and whether this sensitivity could be undermined by the availability of management representations.


Demand is growing for a statistically based, nationally consistent definition of frontier territory, one that is adjustable within a reasonable range and applicable in different research and policy contexts. The need arises from Congressional mandates affecting rural health programs and from limitations of previous classification schemes. As used here, the term frontier denotes territory characterized by some combination of relatively low-population density and high geographic remoteness. Two features distinguish the methodology described here from earlier classifications. First, the approach strives for the most accurate measures of distance possible for the smallest units of geography containing population data. Travel time by car to nearby urban areas is calculated for coterminous US territory at the 1 × 1 kilometer grid level. Once frontier territory is delimited at the grid level, frontier populations may be summed to ZIP code areas, as demonstrated on the Main Map, or to census tracts, counties, or other useful geographic entities. Second, travel-time thresholds around urban areas were allowed to vary by urban-area population size. This is desirable because the effect of urban population size on adjacent rural population density is discontinuous. At any given distance from an urban area, population density increases as the size of the nearby urban area increases.


The concentration of algal water in a raceway pond is around 0.5 to 1 g of whole-cell biomass per unit volume (liter) of liquid. Because of its dilute nature, dewatering the microalgae suspension can account for a significant portion of downstream processing costs and is thus a significant challenge for the sustainability of industrial-scale algal processes. The solvent phase algal migration (SPAM) process presented here is a technique designed to separate suspended algal cells from their aqueous phase to a solvent while simultaneously displacing water. This investigation evaluates the dewatering performance of five factors pertinent to the SPAM process: algal surface modifier type, algal surface modifier concentration, solvent fraction, migration time, and initial algal broth concentration. The investigation revealed that the initial algal broth concentration, surface modifier type, and solvent fraction significantly affected the level of algal migration during the SPAM process.


A field experiment was conducted in the experiment fields of the college of agriculture Abu ghraib Baghdad University, 2016 in a silt clay loam soil , to study the effect of soil moisture content and the speed of the tractor on some tractor performance indicators and some of soil physical characteristics, ArmaTrac 845e and ITM 285 New tractor with sweep plough as a machinery unit were used in this study .Two soil moisture content under 18 20 % and 14 16 % which represented main plot, Three types of plough included : moldboard , chisel and sweep which represented subplot, five levels of foreword speeds of tractor included : 1.5 , 2.53 , 3.75 , 5.3 and 6.71 km / hr which represented sub-subplot. Slippage percentage, Pull force, Effective field capacity, soil moisture level and soil bulk density were measure in this experiment. Split-split plot with complete randomized block design with three replication were used in this study, and Least significant differences (LSD) was used to compare the means of treatments at 0.05 levels. The obtained results, for the range of tests, showed that the Reducing soil moisture content from 18 20 % to 14 16 % caused decreasing slippage percentage by 31.34 % and force pull by 26.14 % and the low value of soil bulk density from 1.25 g/cm3 to 1.24 g/cm3 and low soil moisture level by 20.92 % to 18.76 % and increased effected field capacity by 12.5 %. Increased tractor speed operation led to increase the percentage of slippage and force pull and production field and soil bulk density and the weighted reduce soil moisture level. The interaction between soil moisture content 14 16 % and the speed 1.5 km/hr got a less percentage of slippage 6.36 % and less force pull 6.26 kN and less soil bulk density 1.12 g/cm3, And the interaction between soil moisture content 14 16 % and speed 6.71 km/hr got higher value of the effective field capacity 1.57 he/hr, And the interaction between soil moisture content 18 20 % and the speed 1.5 km/hr gave a higher soil moisture level 21.25 %.

Hepatitis C complicated by diabetes mellitus (DM) is considered a risk factor for the progression of fibrosis and development of hepatocellular carcinoma (HCC) and cardiovascular diseases. However, several studies may have lacked appropriate diagnosis of glucose intolerance. We aimed to examine the risk associated with abnormal glucose intolerance in the development of liver‐related diseases, including HCC and complications of liver cirrhosis, such as ascites, esophageal and gastric varices, and hepatic encephalopathy, and cardiovascular diseases in patients with hepatitis C accurately diagnosed with impaired glucose tolerance.


A new screening model in female rats for examination of unknown synthetic estrogens with regard to oral antifertility activity is described. The administration of substances was begun during metestrus or diestrus and lasted for 5 days (maximally until Day 4 of pregnancy). For evaluation of the antifertility effect 2 indices (FH1 and FH2) were used. Mestranol (17alpha-Ethinyl-3-methoxy-estra-135(10)-trien-17beta-ol) showed an MPD 100 of 8.0 mg/kg and ED50 of 1.75 mg/kg and BDH 2398 (17alpha-Chlorethinyl-3-methoxy-estra-135(10)-trien-17beta-ol) of 2.0 mg/kg and .50 mg/kg respectively (related to FH1). By administration of subeffective doses frequency of fetal death was significantly increased for both substances. The corresponding doses ranged from 2.0 to 4.0 mg/kg mestranol and .5 to 1.0 mg/kg BDH 2398. (AUTHORS MODIFIED)


Background:  Inguinal hernia repairs consume an important part of health care resources because of the high incidence of the problem. It is estimated that 20 millions of inguinal hernia repairs are performed globally every year. Every recurrence after a primary repair will add an extra cost to health care economics. Moreover, secondary or tertiary operations after previous repairs carry higher risk of re-recurrence and specific complications like testicular atrophy. Therefore, every surgeon should know and perform a current repair method successfully in his/her daily practice. The aim was to compare the efficacy of prolene hernia system with that of lichtenstein mesh repair in terms of early and late complications, operating time, time of return to work, chronic pain and recurrence . Methods: 200 patients reporting and found eligible for the study were selected. They were divided into two groups. One group of 100 patients underwent the prolene hernia system type of surgery. Other group of 100 patients was operated by using Lichtenstein mesh repair. VAS score was used to assess the pain among the patients post operatively. All patients of both the groups were followed for a period of 10 years from August 2006 yearly to assess the occurrence of complications and recurrence among them. Results:  It was found that mean duration of surgery was lesser in PHS group of 25 minutes compared to 35 minutes in other group. On comparison of post-operative pain assessed by VAS score, it was found that the PHS group patients experienced only mild pain compared to mild to moderate pain in other group patients. Patient compliance was excellent in the PHS group compared to the other group. Patients in the PHS group were able to return to their work within 15 days compared to 30 days in other group. Conclusions:  Reports of this device (PHS) are encouraging, operating time is shorter and there is quick recovery. PHS provides all advantages of a tension - free repair, provides a stable anterior repair with added benefits of a posterior as well as plug repair. The high risk group of patient may be a good target as superior primary repair.


This study aims at addressing English teacher's perspective about integrating WhatsApp (WA) into a university-level English class in STAIN Mandailing Natal. The data includes interviews with the teacher and observation on class postings in WA group and student-teacher timeline for four meetings. The data were analyzed qualitatively, and interpretively, resulting in three emerging themes about the WA to teach English remotely in low-tech classroom: the implementation of WA for online teaching, managing online learning activities in WA group and teacher's constrains in applying WA in teaching online. The result of analysis indicates that WA is considered effective to teach English remotely in a limited internet connection classroom. With some adjustments to the instructional design, teaching and learning process could run well. However, due to the lack of students-teacher direct interaction, virtual class could not go as engaging as face-to-face learning in the classroom.


The article investigates the composition of administrative offences and corruption-related crimes on the subject of "declaring inaccurate information about property and income", criminal and administrative liability for their commission. Based on the comparative and legal analysis, the main differences of the mentioned corruption offences' structures have been determined. It has been established that the basic differences in the composition of corruption administrative misconduct and corruption-related crime refer to the object (the value of the property concerning which inaccurate information has been submitted) and the subjective aspect. The distinctions in liability have been determined for submitting of deliberately inaccurate information in the declaration by the subject regarding the property or other objects of value. Judicial practice reveals that in case of an administrative offence, "the submission of deliberately inaccurate information" refers to the subjective aspect, whereas the qualification of a corruption-related crime takes place in the case of deliberate misrepresentations about property value by the declarant. Analysis of judicial practice in the Unified State Register of Judicial Decisions has revealed the following features: a fine is a common form of punishment; imprisonment is much less often used; evidence of fact that a person has committed an act in the form of non-filing, untimely submission of the declaration or submission of inaccurate information in the declaration is sufficient to make a conviction; lack of a thorough investigation of the subjective aspect of crimes with a predominance of judgments in favor of intent or submission of inaccurate information in a declaration; lack of a detailed investigation of the subjective aspect of crimes with a predominance of judgments in favor of criminal intent.


The untapped potential in foreign trade among Latin American countries is tremendous. Regional economies are going at a much faster pace than those in traditional markets, such as the U.S. and EU.


✓ Five patients are described with cerebral microglioma or reticulum cell sarcoma. The tumors varied from local neoplasms to multicentric or miliary foci. One of these patients is the second case reported of a microglioma associated with Waldenstrom's macroglobulinemia. Serum electrophoresis on the other four patients did not reveal any consistent abnormality or pattern. Immunoglobulin studies performed on three of the five patients confirmed Waldenstrom's syndrome in one, revealed an elevated IgA globulin in a second, and was normal in a third. Cerebrospinal fluid findings included elevated spinal fluid protein in all five patients. The brain scan was abnormal in all four cases so tested. Arteriograms in four patients demonstrated tumor blushes indicative of increased numbers of enlarged vessels. The relationship between reticulum cell sarcomas originating in the central nervous system and those originating elsewhere is discussed.


This paper presents the results of an experimental investigation into the effect of lubrication and the tool type on thrust force and torque during the drilling of unidirectional glass fiber-reinforced plastic (GFRP) laminates. It is well-known that the most effective way of achieving good quality of holes while drilling fiber-reinforced plastics (FRPs) is by reducing the thrust and torque. Therefore, this investigation was aimed at exploring the possibility of reducing the thrust force and torque by using the concept of trepanning. The design considerations and development methodology of trepanning tools and twist drills are discussed. The appropriate tool has been determined by using statistically planned experiments and analysis. Orthogonal arrays with analysis of means as well as analysis of variance have been used to assess individual factor and interaction effects and their significance levels. The investigations have revealed that the performance of the trepanning tool was superior to that of the twist drill in terms of thrust force, torque and hole quality, as well as the influence of lubrication conditions.


The allotriploid Phytophthora x alni (Brasier & S.A. Kirk) Husson, Ioos & Marcais and its progenitors, the diploid P. uniformis (Brasier & S.A. Kirk) Husson, Ioos & Aguayo and the allotetraploid P. x multiformis (Brasier & S.A. Kirk) Husson, Ioos & Frey are the causal agents of alder decline in Europe. In June 2015, a dark, ca. 40 mm stem lesion was found on one out of 100 inspected Alnus glutinosa (L.) Gaertn seedlings in Mantyharju, Finland. Surface wood pieces from the lesion edges were plated onto malt agar (MEA). Cultures on carrot piece agar (CPA) showed appressed colony with woolly aerial mycelium. Oogonia (O mean 44.8 µm, n = 50) and oospores (O mean 40.0 µm, n = 50) developed after 7 days at 20 °C in the dark. They were commonly smooth walled and 49 out of 50 of the amphigynous antheridia were single celled. Sporangia (21.7 µm x 18.1 µm, n = 50) were produced on pea broth, with 2-day flooding with soil extract, and they were commonly unpapillate and obpyriform-ellipsoidal. DNA was extracted and t...


The present study deals with the effect of several preservation methods on the behaviour of incus grafts in rats after orthotopic and heterotopic transplantations. The following conclusions can be drawn: 1. Preservation seems to influence both the potential for new bone formation and the antigenic properties of an ossicular graft. 2. Preservation in cialit and alcohol and freeze drying preserves the osteogenic properties to a variable extent. 3. Bone formation is absent after boiling and after preservation in formaldehyde. 4. The antigenic properties are affected by storage in alcohol and cialit and by boiling. 5. Preservation of the antigenic properties of the graft does occur after freezing and freeze drying and after storage in formaldehyde. 6. Typical reaction of transplantation and resorption of the graft are only observed after heterotopic transplantation in muscle.

Geothermal investigations in Serbia began in 1974, after the first world oil crises. In 1990, a first assessment of geothermal resources has been made for all of Serbia. The territory of Serbia has favorable geothermal characteristics. There are four geothermal provinces. The most promising are the Pannonian and Neogene magmatic activation provinces. Age of certain granitoid rocks and their volcanic products is estimated using K/Ar method. Age of the examined rocks ranges from 30 to 10 million years. The analyses are made for an estimation of the energy potential in geothermal resources. For the granitoid plutons of Serbia, the age has been found dependent on hypsometric position of sampling sites. This may be explained by magma solidification inside the pluton 10 to 13 million years later than that of its upper portions. This is very important for the estimation of its present geothermal resources, or an estimate of its available HDR resources. Smith & Shaw, 1975 showed that granitoid massifs of Kopaonik, Cer and Golija are feasible for exploitation of HDR geothermal resources. This is expected to be corroborated by the next geothermal exploration and a new age estimation by K/Ar method.
