One often observes that despite the efforts involved on information systems development, many times the achieved solutions do not comply well with the needs of the organization and lack in change agility to face new emerging requirements. This paper conceptualizes about an architectural framework specifically designed for explaining and representing the working environment of enterprise operating systems (EOS) and non-EOS information systems (IS) that depend on it. With these concerns in mind, the goal of EOS is to capture and control all phenomena that occur in an organization and then to provide all the required data for all IS for that organization. Using a computer engineering metaphor, this paper defines the theoretical foundations, and the methodology to design and implement an operating system for organizations. To achieve this, EOS is a model-driven dynamically. The models are based on domain ontology with C4-ness qualities and expressed in ontological language. It will be shown that the theory of enterprise ontology and the DEMO methodology provide a high degree of ontological appropriateness for this domain. This paper, outline a framework with its foundations, concepts, principles and stratification of IS, which is a radical new approach, useful to discussion this solution among the practitioners. A methodology to apply this architectural framework is discussed using a professional production case management.


Burkitt lymphoma is frequent a cancer in the developing countries where its treatment is based on non‐intensive chemotherapy protocols. The purpose of this study was to assess the effectiveness and the toxicity of a non–intensive chemotherapy protocol combining cyclophosphamide and methotrexate in children with Burkitt lymphoma of the maxillofacial region.


The design and implementation of a multiprocessor-based uninterruptible power supply (UPS) are presented. A digital-power factor compensator is proposed for the closed-loop regulation of the synchronously controlled rectifier. Digital sinusoidal pulsewidth-modulation (SPWM) techniques with a digital compensator are used to regulate the PWM inverter of the UPS. Fast transient response and high efficiency have been obtained. A 5 kVA transistorized UPS has been built in the laboratory, and experimental results have shown its superiority.<<ETX>>


Continuous transverse stub (CTS) is an antenna technology that offers greater tunable bandwidth than waveguide or patch antennas, efficiencies of over 60% and polarization isolation of 25-50 dB. This technology is also low cost, relatively insensitive to fabrication tolerance, and when combined with the ferroelectric material technology, it provides beam steering capability. For wireless communications applications, omnidirectional radiation patterns and improved feeding arrangements may also be required to further simplify the design and improve the impedance matching characteristics. To this end, we recently designed a coaxial version of the CTS technology, and experimentally verified its radiation and impedance characteristics.


The hypothesis that numerical ocean circulation models could benefit fishery management was tested by first simulating the interannual variability of the northeast Pacific Ocean from 1955 to 1979 with the Bryan–Cox–Semtner ocean model (from the Geophysical Fluid Dynamics Laboratory, Princeton, NJ) and then relating the model output to the interannual variability found in the Fraser River sockeye salmon (Oncorhynchus nerka). Empirical orthogonal function (EOF) analysis was first used to condense the model output fields as well as the atmospheric forcing data. Next, the amplitude of the EOF's were regressed with the annual values of the sockeye variables (return migration route and timing, marine survival, and fork length) by stepwise multiple regression, with various time lags between the physical and the sockeye variables. The EOF modes associated with interannual variability (usually mode 2) were more often correlated with the sockeye variables than the other modes thought to contain mainly the seasonal ...

Problem statement: Demand considered in most of the classical inventory models is constant, while in most of the practical cases the demand changes with time. In this study model has been framed to study the items whose demand changes with time and deterioration rate increases with time. The effect of permissible delay is also incorporated in this study. The objective of this research is to develop an inventory model for perishable items whose perish-ability rate as well as demand increases with time Approach: Firstly, problem is framed in the form of linear differential equation model and this model had been solved using general solution techniques of linear differential equations. The solution obtained gives the inventory level at any particular time of the cycle period. With the help of this inventory level, total as well as average inventory cost has been obtained. Results: This study developed a model to determine an optimal order quantity by using calculus technique of maxima and minima. Thus it helps retailer to decide its optimal ordering quantity under the constraints of variable deterioration rate and linear pattern of demand. Conclusion: Numerical solution of the suggested model had also been proposed, the above model can be converted into constant demand model, or for items having no deterioration. This study can further be extended for items having some other demand pattern, also time value of money and inflation can be incorporated in this model to make it more realistic and present business environment suited.


Let $R$ be a prime ring with center $Z$ and $I$ be a nonzero ideal of $R$. In this manuscript, we investigate the action of skew derivation $(\delta,\varphi)$ of $R$ which acts as a homomorphism or an anti-homomorphism on $I$. Moreover, we provide an example for semiprime case.


One of mathematical modelling to assess relative efficiencies of the group of the decision making unit in production systems is Data Envelopment Analysis (DEA). In this study, we use DEA to assess relative efficiencies in the production process of making stamped batik of 16 SMEs which is located in Pekalongan, Solo, and Yogyakarta. The general conclusion that there is a variance of efficiency among the SMEs, indicating some SMEs has misallocation or inefficient of application of using worker, mori, wax, dyestuff, water, and fuel in the production process of making stamped batik. Additionally, this study provides output target values for improving the efficiency. Overall, this study gives confirmation of how the DEA approach as the advances and recent development in efficiency analysis can be applied for an effective evaluation of performance in SMEs stamped Batik.

Aim of the present study was to investigate whether 4-years continuity of teacher rated hyperactivity and inattention symptoms were associated with lower academic performance in language, mathematics, and total grade average. Gender, age, fluid IQ, previous academic level, and teacher reported Strengths and Difficulties Questionnaire (SDQ) total problems score at the first assessment were controlled in an urban low-middle-income-country setting. The follow-up sample with full SDQ data consisted of 967 students (boys: 523, 54.1%; girls: 444, 45.9%) from fifth to eight grades. Using cut-off 7 for SDQ Hyperactivity score for each assessment, the students were categorized into four groups: continued group (CG) (4.4%); declining group (DG) (6.9%); increasing group (IG) (9.0%); and consistently low (LG) group (79.6%). In the follow-up assessment, CG and IG had significantly higher SDQ scores when compared with both DG and LG and DG had significantly higher SDQ Hyperactivity and Total problems than LG. CG had significantly lower Mathematics, Language and Total average when compared with all other groups. IG and DG had significantly lower Mathematics, Language and Total average than LG. In regression analysis, odds ratios for CG students were between 5,1 to 7,4 for being in the lowest 25 percentile in all courses. These results imply that teacher reports of hyperactivity and inattention are significant predictors of academic failure, even when the symptoms are below threshold. Therefore, screening students for hyperactivity and inattention early and starting interventions early may be an effective policy to prevent academic failure.

Thirty-five pineal biologists, including 3 from Europe, participated in this National Symposium. The symposium had nine distinct scientific sessions and each session dealt with topics of current interest involving pineal or its principal product, melatonin.


A salen-based ruthenium (Ru) (II) complex was synthesized for possible use in nonlinear optical device applications. The Ru complex was doped in a polymer matrix to fabricate films using a low-cost spin-coating technique. The third-order nonlinear optical parameters of the complex were investigated by Z-scan and degenerate four-wave mixing techniques. The study reveals two-order enhancement of third-order optical susceptibility χ(3) and exhibits superior limiting capability due to a reverse saturable absorption process. All-optical switching action for the films indicates that the sample can function as an optical inverter or a NOT gate. Hence, the Ru (II) Schiff-base complex materializes as a possible candidate for use in nonlinear optical devices.

The Iterative Closest Point Algorithm module is the file icpa.dll. If this DLL exists in the directory of EIKONA3D when the program starts, a sub-menu called ICP Algorithm is added under the Modules menu. The menu options of this sub-menu provide two methods (Classical and Morphological) of Iterative Closest Point Algorithm (ICPA). The Classical method accomplishes the original ICPA which proposes a solution to a key registration problem in computer vision: given a cloud of 3D model points and a cloud of 3D data points, estimate the optimal translation and rotation that register the two point clouds by minimizing the mean square Euclidean distance between them. This method is described in [1]. A crucial drawback of this method is the high computational complexity of the closest point operator. The Morphological method solves this problem by using a 3D array representing a volume and by constructing the Voronoi diagram of the model points within this volume, by using the morphological Voronoi tessellation method. Then, the ICP algorithm is employed, with distance calculations substituted by simple array references. An important application of the Iterative Closest Point Algorithm is to register actual data sensed from a 3D object with an ideal 3D model. It is also useful in multimodal 3D image registration in medical imaging (e.g. between NMR and CT volumes), in the shape equivalence problem, as well as in estimating the motion between point sets when the point correspondences are not known. The procedure followed for each method in our module is described below: 1. Classical ICP Algortihms This menu option performs the Classical ICP algorithm. In this method the user has first to select the model and data volumes (Figure 1-2) which can be only grayscale. Normal projection of the object seen in Figures 1-2 can be seen in Figure 3. It is strongly recommended that the model and data volumes should have the same size. Then he has to define the appropriate parameters for the Initial Rotation Vector and the Threshold through the Classical ICP Algorithm dialog box (Figure 3). These two parameters are described in detail below.

The magnet yokes for most of the Hadron Electron Ring Accelerator magnets are made from 5-mm thick fine-blanked laminations. Differences in the measured and calculated field distributions using the specified values for the relative permeability are explained by distortions of the magnet steel caused by cold deformation in the cutting edge zones during the fine blanking. A comparison of fine-blanked, laser-cut and lathe-turned annular samples made from the same starting material shows that a reduction of the relative permeability and an increase of the coercive force depend strongly on the volume of the areas distorted in the fabrication process. Better agreement between calculated and measured field distribution was achieved by using properly chosen permeability curves taking into account the cold deformation from the lamination production. The influence of the production process on the magnetic properties of laminations can be reduced and even completely mitigated by additional heat treatment. >


Taking the 'first resurrection' (Rev 20.4–6) as 'heaven' accords with early Christian, non-chiliast views of martyrs and other blessed. Exegetical development of this interpretation requires plotting (in line with the literary structure of Rev 4–22) the convergence of complementary eschatologies: first, the millennium brings to a climax a series of images expressing 'vertical' eschatology (the life of God's witnesses after death); second, the whole narrative focuses fulfilment of the Creator's scroll ('what must take place [γενε´σθαι] hereafter') on the very end of the end-time (i.e. 'horizontally', on the moment marked by the enthroned's voice in 16.17, γη´γoνην, and 21.6, γη´oναν: 'It/They has/have taken place'), and on God's victory over those gathered by powers of deception for 'the war' at Armageddon (16.12–16; 19.19–21; 20.7–10). Christ's kingdom in heaven is followed by the advent of God's sacred kingdom on earth.


We investigate the existence, characteristic multipliers, and stability of periodic solutions to a Hamil- tonian vector field which is a small perturbation of a vector field tangent to the fibers of a circle bundle. Our primary examples are the planar lunar and spatial lunar problems of celestial mechan- ics, i.e., the restricted three-body problem where the infinitesimal is close to one of the primaries. By averaging the perturbation over the fibers of the circle bundle one obtains a Hamiltonian system on the reduced (orbit) space of the circle bundle. Our goal in the first part of the paper is to state and prove results which have hypotheses on the reduced system and have conclusions about the full system. Starting with the classical work of Reeb, we give a summary of lemmas, corollaries, and theorems about the existence, characteristic multipliers, and stability of periodic solutions to Hamiltonian systems which are perturbations of circle bundle flows. By reformulating the classical results in modern language and giving alternative proofs in place of the original proofs, we are able to infer new consequences of these classical results. The second part of the paper is devoted to applications of the general results. We apply these general results to the planar and spatial lunar problem. After scaling, the lunar problem is a perturbation of the Kepler problem, which after regularization is a circle bundle flow. We find the classical near-circular periodic solutions and the near-rectilinear periodic solutions. Then we compute their approximate multipliers and show that there is a "twist." However, the twist is too degenerate to apply the classical KAM theorem on invariant tori. We also find symmetric periodic solutions which are continuations of elliptic solutions of the Kepler problem.

Many reports have discussed the swelling behavior of photoresists during development, as observed by the QCM method. Previously, we reported on the development of development analysis equipment based on the QCM method. In this paper, we report on a high-precision resist development analyzer also based on the QCM method. This equipment incorporates a high-precision developing solution temperature controller and features a high-precision air conditioning function for the measurement chamber. We also measured swelling behavior during development using a TBAH developer solution, which features larger molecules than TMAH, comparing these results with those obtained with TMAH. The results of this measurement indicate that the extent of resist swelling during development is less with TBAH developer solution than with TMAH developer solution. This result is consistent with results of a study by Itani et al. using high-speed AFM, suggesting the suitability of the measurement equipment used in our experiments.


The autosomal dominant cerebellar ataxias (ADCA) are a clinically heterogeneous group of neurodegenerative disorders characterized by a predominantly cerebellar syndrome of onset with gait ataxia, dysarthria, dysmetria, and dysdiadochokinesia. Pathologically, the disorders are characterized by premature neuronal loss in the cerebellar cortex and the inferior olivary and pontine nuclei, with degeneration of the spinal cord. We have previously assigned the spinocerebellar ataxia 2 locus to chromosome 12q23-24.1, within a 31-cM interval flanked by the loci D12S58 and PLA2. Linkage to SCA2 has been demonstrated in pedigrees from Europe, Japan, and North America, the latter serving to refine the candidate region to a 16-cM interval. We report here genetic analysis undertaken between SCA2 and nine microsatellite loci known to span 8 cM within this interval. 12 refs., 2 figs., 1 tab.


Aims. The aim of the paper is to give a physical explanation of the absence of the feature in the Calzetti extinction curve. Methods. We analyze the dust attenuation of a homogeneous source seen through a distant inhomogeneous distant screen. The inhomogeneities are described through an idealized isothermal turbulent medium where the probability distribution function (PDF) of the column density is log-normal. In addition it is assumed that below a certain critical column density the carriers of the extinction bump at 2175 A are being destroyed by the ambient UV radiation field. Results. Turbulence is found to be a natural explanation not only of the flatter curvature of the Calzetti extinction curve but also of the missing bump provided the critical column density is NH ≥ 10 21 cm −2 . The density contrast needed to explain both characteristics is well consistent with the Mach number of the cold neutral medium of our own Galaxy which suggests a density contrast σρ/� ρ� ≈ 6.

The article presents the issue connected with the application of the mechanism
of real property communalisation in Warsaw, raising a great deal of doubt in literature
and diversely assessed in the case-law. The issue concerns the requirement
adopted by the communist authorities in the decree of 26 October
1945 on ownership and usufruct of land on the area of Warsaw (so called
the Warsaw decree) pursuant to which persons applying for (former) heritable building rights
of superficies, and currently the right of perpetual usufruct were possessors of their former
real properties. The decree communalised (nationalised) all land plots within Warsaw
in order to rebuild the city destroyed by the war. A person fulfilling the condition
of possession or their legal representative could have submitted within 6
months from taking possession of the land by the commune a request for establishing
the right allowing the use of the real property compulsory taken over. Granting
the possibility to submit requests for establishing the right to the land was to enable
its former owners to take part in the reconstruction of the capital city. Granting
the right involved essential obligations, for example in the form of the construction
of a building or other facility as well as their maintenance in an appropriate condition.
The main controversy concerns the fact whether the possession order
as the condition for granting the right to use the land by the commune relates
to former owners or only their legal successors (including mainly their heirs). If the interested
party did not own the real property, they could not have claimed the right to establish the
right to the land in an efficient way. The requirement concerning the ownership as the possibility
to exercise efficiently the actual control over the real property was assessed under the
rules of the Napoleonic Code applicable in the central parts of Poland, whereas later under
the new Polish property law of 1946. The ownership as the condition for acquiring the right
to the land was aimed at establishing the possibility to co-participate in the reconstruction
of buildings destroyed as well as allowed the determination whether the persons entitled to
the land were alive or had died during the years of war turmoil (in particular in the Holocaust).
The article presents arguments for assuming the necessity to analyse the existence
of the ownership lying with former owners (and not only with their legal successors).
Nowadays, the problem is also essential due to practical reasons as requests submitted
in the 1940s are being still currently processed, and failure to prove in that time
the title to the land by requesters applying for granting the relevant right results
also today in the necessity to reject establishing the right of perpetual usufruct.


Jim and Dave Defeat the Masked Man is the lampoon of misdeeds high and low in American Poetry. Many of the poems here are hilarious, virtuoso stand-up performances, accomplished formally through the roller-coaster ride of the sestina by an unlikely tag-team duo: James Cummins and David Lehman. However, in a twist, to resist identification, the book refuses to credit which author wrote which sestina until its very end. Theoretically, this should shift focus squarely to the poems. However, funny as the poems are at times, the dual authorship creates a lingering problem: if comedy that strikes at the powers that be tends to spring from the margins where it hones its edge, then clearly, as the poems in fact bear out, one poet in Jim and Dave Defeat the MaskedMan will be funnier than the other. The biggest surprises, and the best laughs, in Jim and Dave Defeat the Masked Man arrive in poems where Dave and Jim—or is it "Dave" and "Jim"?— appear as their own characters. For example, in the poem "David Lehman & Jim Cummins Parachute into Iowa City," Dave and Jim are charged with rescuing Iowa's MFA program from surrealism gone wrong:


About an hour and a half before the launch of the Orbital Sciences Corporation's Antares rocket and Cygnus cargo spacecraft at 6:22 p.m. on 28 October, Jeff Goldstein arrived at his vantage point on Arbuckle Neck Road in Assawoman, Va. It was just 1.5 miles from launchpad 0A at NASA's Wallops Flight Facility. Goldstein, director of the National Center for Earth and Space Science Education (NCESSE) had come with about 35 elementary school through college students, as well as some parents, teachers, and school administrators, to watch the liftoff that would deliver the students' microgravity experiments to the International Space Station (ISS).

The author describes the key conceptual metaphor, structuring the conceptual system of concessivity category, analyzes it taking into account the reflected features of its perception, the conceptualization and categorization of reality by a man, and comes to the conclusion that the key conceptual metaphor of concessivity category is based on a spatial metaphor, basing on the adaptation of new knowledge with the involvement of the cognitive structure of subject's existing knowledge.


To see how closely an interacting-boson-model-like model can be approached, we systematically develop a similarity transformation that unitarizes the simple correspondence version of the Dyson boson mapping of the Ginocchio SO(8) model. For a large region of Hamiltonian parameter space, a one-body plus two-body Hermitian boson Hamiltonian of the interacting-boson-model form is achieved. The similarity transformation consists of a dynamical part and a normalizing part. The dynamical transformation results in a one-body plus two-body Hermitian Hamiltonian and simple transition operators. The normalizing transformation commutes with the dynamically transformed Hamiltonian. This enables the transition rates to be calculated without introducing dual bases. However, the resulting boson model differs from the phenomenological interacting boson model in that transition rates are not calculable from the absolute squares of matrix elements. Dynamically transformed operators are given explicitly, and normalizing transformations for SO(6) and seniority limits are obtained in closed form.


Dermatomyositis is an idiopathic inflammatory myopathy with the diagnostic criteria for the disease being typical cutaneous features, progressive proximal symmetrical muscle weakness, elevated muscle enzymes and abnormal findings from muscle biopsy. Other associations being dysphagia, cardiac disturbances, pulmonary symptoms, subcutaneous calcifications, and symptoms like fever, malaise, weight loss, arthralgia and Raynaud's phenomenon [1]. Various ocular complications and oral cavity involvements are present in dermatomyositis but regretfully, very little information is shared among various specialities regarding these aspects.


Background: Sub-optimal health status (SHS) and unhealthy lifestyle among college students have become a major focus for research on public health worldwide. Hence, this study was designed to assess the effects of socio-cultural factors on medical college students' self-rated health status (SRH) and health-promoting lifestyles (HPL) in Eritrea.Methods: A descriptive cross-sectional study was conducted at Orotta School of Medicine (OSM), using a self-administered questionnaire. Data was collected from all medical students who had fulfilled the inclusion criteria using Sub-Optimal Health Measurement Scale (SHMS V1.0) and Health-Promoting Lifestyle Profile-II (HPLP-II) scale questionnaires. Independent samples t-test, ANOVA, Chi-square test, Pearson's correlation coefficient and Binary multivariate logistic regression were performed. Data analysis was undertaken using SPSS version 22.Results: The overall SRH was significantly higher among college students with BMI of 25 to 29.9 (M=88.23, SD=6.28) as compared to <18.5 (p=0.027) and 18.5 to 24.9 (p=0.027). Moreover, physiological subscale of SRH was significantly related to gender (M males= 88.96 Vs M females= 85.41, p=0.001) and monthly stipend (M income = 89.52 Vs M no-income = 87.28, p=0.040). On the other hand, physical activity of HPL was found to vary by gender (M males= 2.12 Vs M females=1.87, p=0.005) and alcohol consumption (M drinkers= 2.22 Vs M non-drinkers = 1.99, p=0.016). Nutrition differences of HPL were observed in BMI of 25 to 29.9 (M =2.40, p=0.028), internship students (M=2.15, p=0.027), and monthly income (M=2.11, p=0.029). The overall SRH was significantly correlated with the overall HPL (r=0.493, p<0.001). In-addition, students who had good and excellent HPL had self-rated themselves as almost five times (AOR=4.97, 95% CI: 1.28, 19.32), and were 3.73 times (AOR=3.73, 95% CI: 1.09, 12.80) healthier than those who had poor HPL, respectively.Conclusions: Based on our study, gender, BMI and monthly stipend play a major role in the SRH whereas gender, alcohol consumption, BMI, study year and monthly stipend play a major role in the HPL. Moreover, there was a significant correlation between SRH and HPL in this study. Therefore, our findings provide evidence that support the role of socio-cultural influences' on SRH and HPL of medical students.


In recent years, multiple-input multiple-output (MIMO) communication techniques have brought wireless communication to a new performance level. MIMO communication employs multiple antennas at the transmitter and at the receiver and transmits multiple data streams concurrently within the same frequency band. This method, known as spatial multiplexing, increases the spectral efficiency and link reliability without requiring additional transmit power. However, the benefits of MIMO communication come at the cost of, at least to some extent, significantly increased computational complexity compared to single antenna systems, especially in the receiver. To identify strengths and weaknesses of new technologies (e.g., MIMO communication), rigorous testing and experimentation is required. To this end, so-called testbeds are built that serve as experimentation platform. In this thesis, the design of a modular hardware platform (i.e., testbed) for testing and experimentation of MIMO communication aspects is described. The field-programmable gate array (FPGA)-based platform is able to operate in real-time, i.e., all the signal processing tasks are carried out at least as fast as new data are arriving at the radio frequency (RF)-input. To this end, the baseband MIMO physical (PHY)-layer is implemented on two large FPGAs and a basic media access control (MAC) layer has been realized on the PowerPC of one of the FPGAs. The baseband processing of the MIMO PHY layer on the testbed is similar to the IEEE 802.11a standard and uses orthogonal frequency division multiplexing (OFDM) as modulation method. The same hardware platform can also be used as offline testbed. In this setup, the data are prepared on a personal computer (PC) and transmitted over a real-world RF chain. On the receive side, the data are recorded and again processed on a PC. The main advantage of this setup is that different MIMO algorithms can be tested more


Early 20th century book collector Otto Ege removed pages from medieval texts and regrouped them into forty boxes now scattered around the United States, Canada and Europe. The University of Saskatchewan, in partnership with other institutions holding the boxes, is in the process of locating as many as possible with the goal of digitally reassembling at least one of the original texts. The project has had the unanticipated effect of focusing scholarly and public attention on the unit of the individual page as opposed to the more familiar object of scrutiny, the book.

Historical records of occurrence of the European Roller Coracias garrulus in Croatia are examined to determine its former breeding distribution in Croatia. The European Roller once bred in lowland region of Croatia and was most numerous in river valleys. As in most other parts of its European breeding range, it suffered a severe decline and finally went extinct in lowland region. The last confirmation of its breeding in lowland region was from Hrvatsko Zagorje from the 1980s. At the same time, in the 1980s, breeding was for the first time recorded in the coastal region, in Ravni kotari. After almost thirty years without confirmations, breeding was again confirmed in Ravni kotari in 2010. Following the rediscovery, a monitoring program was initiated in 2011. Subsequently, breeding attempt was also recoreded in Istria. Launching targeted conservation measures is urgently needed to preserve the European Roller as a breeding bird in Croatia.


The purpose of this research was conducted to analyze: (1) To what extent does the number of people affect open-mindedness in Indonesia, (2) To what extent does education influence open-sensitivity in Indonesia, (3) To what extent does open inequality affect responsiveness in Indonesia, (4) To what extent does population, education and income inequality influence open resistance in Indonesia. This research is a descriptive and inductive type of research. The data used is secondary panel data for 34 provinces in Indonesia from 2017-2021 obtained from related institutions and then analyzed using panel regression models and Random Effect selection models.

Furthermore, partially (1) population has a positive and insignificant effect on open responses in Indonesia. (2) Education has a positive and significant effect on open response in Indonesia. (3) Inequality has a positive and insignificant effect on open responses in Indonesia.


Sufficient conditions for the existence of C2n-2 positive solutions as well as C2n-1 positive solutions of a class of singular super-linear boundary value problem of higher order differential equations are obtained by using a fixed point theorem of cone expansion and cone compression of norm type.


To test control effect of Fusarium oxysporum CS-20 against cucumber fusarium wilt in seedling stage,Fusarium oxysporum CS-20 and pathogenic bacteria were inoculated in cucumber seedlings successively,and its control effect was evaluated in terms of inoculation concentration and acting time.The results showed that when acting time and inoculation concentration were 11 d and 4×106 cfu/mL,the control effect of Fusarium oxysporum CS-20 against cucumber fusarium wilt was the best.


Objective: To understand the bearing capacity and injuring to the bone about three kinds of internal fixture for treating of the intertrochanteric fracture.Methods:The anti bending test is done with a machine (MTS810),and the volume of proximal arm is measured with a graduate.We divided the proximal arm into two parts whole length and proximal 50mm length,to measure the volume.Results:In the anti bending test,the average pressure they can bear is Less than 44.61kg on McLaughlin's nailplate,81.53kg on 130degree blat plate,227.43kg on Dynamic hip screw(DHS).The volume of McLaughlin's nail plate and 130degress blad plate are less,and that of DHS is the largest.Conclusion:The pressure born by the McLaughlin's nail plate is the least,so the operated hips can not bear weight and can not do the functional exercise at the early stage after operation.The pressure born by DHS is the most,so the operated hips can bear weight and do the functional exercise at the early stage after operation.130degree blad plate is the middle.The proximal arm of the McLaughlin's nail plate and 130degree blat plate breaks the neck of femur and the intertrochanteric region less,but DHS breaks them more.


In this work, a new facile green method was proposed to prepare monodisperse magnetic nanoparticles at room temperature with controlled shape and size. In this respect, a new ionic liquid based on 1-allyl-3-methylimidazolium oleate (AMO) was prepared and applied as a capping and stabilizing agent for magnetite at low temperature. The chemical structure, morphology, particle size, crystal structure and monodispersity of magnetite capped with AMO were determined. The magnetic properties and porosity of the prepared magnetite nanomaterials were evaluated using different analytical techniques. The efficiency of the prepared magnetite nanomaterials as an oil spill collector confirmed their high selectivity and oil collection efficiency on the surface of seawater using a low concentration of nanomaterials in relation to the size of the crude oil spill.


Objective To prospectively evaluate the health-related quality of life(HRQOL)outcomes in patients undergoing laparoscopic total mesorectal excision(LTME)with anal sphincter preservation(ASP)for low rectal cancers.Methods From June 2001 to March 2004,125 patients undergoing LTME and 103 patients undergoing OTME were included in this study.The international standard questionnaires(QLQ-C30 and QLQ-CR38)were used to evaluate the conditions of patients at 3 periods after surgery respetively:3-6 months,12-18 months,24 months.Results In contrast to OTME patients,the LTME ones showed significantly better physical function during 3-6 months after surgery,less micturition problems within 12-18 months,less male sexual problems and better sexual function during 12-18 months after surgery,with better sexual enjoyment after postoperative 24 months.Both groups showed significant improvement in most subscales from the first to the second assessment,and improvement in sexual enjoyment from the second to the third assessment.The sexual function,micturition problems and male sexual problems in LTME group significantly improved from the first to the second assessment,whereas the sexual function in OTME group improved from the second to the third assessment.Conclusion Patients undergoing LTME for low rectal cancers have better postoperative HRQOL than patients undergoing OTME,with better physical function,micturition function,overall sexual and male sexual functions in short term,and better sexual enjoyment in the long term.The HRQOL of both LTME and OTME patients may be expected to improve over time,particularly in the first postoperative year.


Dependence is a notion pervading many areas. In this talk, I present a new decidable logic that models both ontic and epistemic senses of functional dependence, and explore its expressive strength and complete proof calculus. The system is a generalized first-order logic and at the same time a modal logic, in terms of notions and proof techniques. I also discuss dynamic extensions when models change, and boundaries with more complex logical systems, e.g., the undecidable modal logic of reasoning about independence. I conclude with comparisons with notions of dependence in linear algebra, causal networks, games, and dynamical systems.


Contemporary understandings of paleoanthropological data illustrate that the search for a line defining, or a specific point designating, "modern human" is problematic. Here we lend support to the argument for the need to look for patterns in the paleoanthropological record that indicate how multiple evolutionary processes intersected to form the human niche, a concept critical to assessing the development and processes involved in the emergence of a contemporary human phenotype. We suggest that incorporating key elements of the Extended Evolutionary Synthesis (EES) into our endeavors offers a better and more integrative toolkit for modeling and assessing the evolution of the genus Homo. To illustrate our points, we highlight how aspects of the genetic exchanges, morphology, and material culture of the later Pleistocene complicate the concept of "modern" human behavior and suggest that multiple evolutionary patterns, processes, and pathways intersected to form the human niche.


Myocardial infarction is uncommon in fertile women. M e n dels o n (I~sz), in a series of 64,992 pregnant women seen in New York during the years 1932-50 found cardiac disease in 2,310 cases, but coronary artery disease accounted for only 4 of these cases. At the medical department of the Municipal Hospital of Kotka, with an average yearly intake of 1,400 patients, we have seen myocardial infarction in only three women under forty years of age during the last nine years. It is therefore evident that the combination of myocardial infarction and pregnancy is very rare. From the literature we have collected 35 cases of myocardial infarction during pregnancy or within one week post parturn, to which material we here add a case of our own (Table I) . This patient is remarkable in that infarction occurred during delivery, a situation we have not found described previously. Pregnancy after myocardial infarction seems rare, too. In the literature we have found only 1 1 such cases, they are recorded without comments in Table 11. This rarity is probably partly to be explained by the fact that a woman having recovered from myocardial infarction usually escapes pregnancy in one way or another. But another explanation could be that not all cases of pregnancy after myocardial infarction have been published.


Abstract We study the linear evolution of a Gaussian pulse injected at different locations along a one-dimensional (1D), hot (T ≥ 6.3 MK) coronal loop, including the dissipative effects of thermal conduction, viscosity, heating, and radiative cooling. We consider both homogeneous and stratified loops of different lengths (50 ≤ L ≤ 400 Mm) and values of the pulse width (or standard deviation, βg/L) between 0.005 and 0.02. We find that a Gaussian velocity pulse can generate propagating waves whose amplitudes increase with increasing width of the pulse. The shape of the waves is quite irregular owing to the superposition of the several harmonics composing the Gaussian pulse. Wave damping due to the combined effects of thermal conduction and viscosity is faster in the shortest and hottest loops. The decay times and periods of the waves are within the observed values of decaying modes of hot SUMER loop oscillations.


Momordica charantia is an anti-diabetic which is used as carminative, emmenagogue, in the treatment of colics, as antiviral, anthelmintic, antimalarial and antimicrobic remedy. The Momordica charantia was treated with Aspergillus niger pectinase at various concentration (0-500 U/ml), temperature (4-40°C) and times (0-10 min). Aspergillus niger was selected as a promising producer of pectinase via solid state fermentation (SSF) using oil palm leaf (OPL) as substrate because it is abundantly available in Malaysia and rich with carbon source that needed for Aspergillus niger'sgrowth. The optimum treatment conditions were at 30°C, at pH between 6-6.5 at time 10 min with 472.257 U/ml. The enzymatic treatment was followed by ultrafiltration (15kDa). Analysis of the clarified juice indicate that the enzyme permitted a higher permeate flux and high juice quality.


Prevention, treatment, and management of pressure ulcers (PUs) is a key indicator of quality, safety, and patient care experience. In the UK, the National Health Service Safety Thermometer (NHS-ST) reports 8.4 million PUrelated data points added 2011– 2018 (NHS Improvement, 2018). However, deep-dive analysis of the NHS-ST data suggests that the largest numbers of new cases of PUs developed in nursing homes and/or community settings, contributing to national PU incidence and prevalence. Implementing a new approach to pressure ulcer prevention


Since the thalidomide disaster over 40 years ago, we have known that medication use in early pregnancy poses a potential risk to the fetus. Yet, drugs typically enter the marketplace and are used in pregnancy without our being able to reliably predict whether they carry teratogenic risk. Premarketing pharmacologic, animal, and clinical studies often fail to accurately identify drugs of concern. In the postmarketing setting, case series and small cohorts of exposed pregnant women, like the ongoing pregnancy registries for newly marketed drugs, can only detect major human teratogens such as thalidomide or isotretinoin. While major teratogens fortunately appear to be few, less dramatic teratogens may be more numerous and more widely used and could therefore lead to a greater excess number of birth defects than major teratogens. The U.S. Food and Drug Administration (FDA) currently uses a system of pregnancy categories ''based on the degree to which available information has ruled out risk to the fetus, balanced against the drug's potential benefits to the patient''. Where there is evidence of risk in humans, medications are classified as D (benefits might make the risk acceptable) or X (unacceptable risk). Class C includes drugs for which there are no human studies available


Indian society today has witnessed a surge of women entrepreneurship. There arises a need to examine the challenges of women entrepreneurs in greater depth. This study attempts to understand these challenges as well as explore the dimensions that emerge from these challenges. The study is based on exploratory qualitative study of 20 women entrepreneurs in India. The narratives reveal six major themes: Desire to create self-identity and derive satisfaction through entrepreneurship, doing what one loves to do, perceiving risk taking as an enjoyable experience, entrepreneurship as a medium to contribute to society, success speaks for itself and willing to learn, unlearn and relearn.


Abstract:We all know that medical wastes are more hazardous than the municipal solid waste and household waste. The medical wastes are the unwanted and discarded materials that are commonly used day by day. Various types of disease-causing agents called as pathogens are found in a high amount of medical wastes. Some commonly caused diseases are parasitic infections, infections of the airways and lungs, meningitis, disease from improperly disposed of with traces of vaccines, bacteremia, infections of reproductive organs, sexually transmitted infections, HIV, hepatitis B and C viruses, and hemorrhagic fevers, and many other diseases. The various wastes generated from the healthcare sectors are needed to be minimized and managed in a safe way. The medical wastes are having a high public risk as it affects the normal environment. The medical wastes are the key factors for environmental pollution. Now a day the medical waste management has become a great challenge and having a critical issue as it is affecting the connected population as well as the environment. The main problem with the unsuccessful waste management can be due to the untrained employees (not known about the waste management) in the healthcare units. Awareness among the health workers for proper medical waste management should be there to create control over the successful minimization the medical waste and its hazardous effect on the public. So the medical waste management, as well as the minimization, is most necessary. This systematic study refers to a brief report on the medical wastes and the possible processes to making the society safe and beware of the hazardous wastes and their management by which the environmental pollution, as well as the public risk, could be reduced.


Phishing is a form of online identity theft associated with social engineering and is a major threat to information security and personal privacy. Now-a-days, phishing plays a very important role in the network attacks. In this paper, we have measured the differences between the fake web pages and the legitimate web pages. For that we have proposed an anti-phishing method, by integrating text- based similarity and the visual based similarity for the identification of the fake web pages. We have implemented two algorithms: one is Scale invariant Featured Transform (SIFT) algorithm used to extract the signatures based on key-points from the screenshot of the web page. Second one is integration of MD5 and SHA used to generate hash value based on the content of the web page. Both of these values have to be stored in the database. In this paper, we have also providing security for the information of the user by using the RSA algorithm those are entered at the time of registration. When any web page is to be checked, then the two algorithms are to be applied to the web page to generate the signatures and those are compared with the values stored in the database. The results are very effective and accurate by using our proposed system. Keywords: Phishing web pages, MD5&SHA, RSA, Phishing, SIFT.


Aiming at the problems for electricity policy researchers to obtain policies related to specific entities, a deep learning model based on Bert-BiLSTM-CRF is proposed to address the problem by recognizing related entities. The model encodes the power policy text with characters through BERT, extracts features from the characters vectors through the BiLSTM network, and generates label sequences through CRF decoding. The experiment reveals that the BERT-BiLSTM-CRF model outperforms other standard models for the recognition of named entities in electricity texts, with the highest F1 score of 88.47%.


The central dogma in molecular biology postulated that 'DNA makes RNA makes protein', however this dogma has been recently extended to integrate new biological activities involving small non-coding RNAs, called sRNAs. In particular, it has been shown that sRNAs regulate the production of proteins by interacting on mRNAs to regulate positively or negatively their translations. That regulation of the mRNA translation is done by forming a base-pairing between the RNAs sequences of bases. In silico methods have been proposed by the bioinformatics community toprovide a list of putative interactions to be experimentally validated. However, such approaches suffers from a poor specificity and therefore produce a large number of false predictions. In this paper, we present a new visualization technique for sRNA-mRNA interactions emphasizing theinvolved regions on the sRNA secondary structure drawing. Our approach also supports interactive exploration as the user can select and highlight interactions. We demonstrate the usefulness of our approach by a case study on E. coli bacteria performed by domain experts.


A review of the methods of obtaining and properties of aluminum matrix composites, discretely reinforced with ceramic particles and nanoparticles of aluminum nitride AlN, is given. The survey shows that at low weight, nanocomposites Al-AlN possess improved physical and mechanical properties, including at high temperatures up to 400-550°C, which makes them very attractive for applications in automotive, aerospace and semiconductor technology. However, due to the long duration and energy consumption, expensive and complicated equipment, low productivity of existing solid-phase methods of powder metallurgy and liquid-phase metallurgical processes of fabrication of nanocomposites of Al-AlN, there are not yet the mastered technologies of industrial production of these composites. Azide technology of self-propagating high-temperature synthesis (SHS-AZ) using sodium azide NaN3 as a solid nitriding reagent allows you to get relatively inexpensive nanopowder of aluminum nitride in the form of nanofibers along with side salt of cryolite Na3AlF6, which can play the role of flux when working with molten aluminum. A new simple ex-situ method of introduction of AlN particles in the molten aluminum alloy in the form of a composite master alloy obtained by fusing together a flux carnallite KCl·MgCl2 with AlN nanopowder mixed with cryolite Na3AlF6 was proposed. Results of experiments on the application of the proposed method for obtaining nanocomposite with matrix made of aluminum-magnesium alloy AlMg6 containing up to 1 % of the reinforcing phase AlN are presented.


Abstract The idea of freedom, or wiathi, lay at the centre of political and moral discussion around the time of Mau Mau. But what did this idea of freedom entail? This article focuses attention on the need to reconstruct what was understood by wiathi by concentrating on the particular context in which the term was used. It is suggested that wiathi denotes an idea of freedom as moral agency, which confers authority to act within the community and makes one fully adult. Although that idea has certain parallels with the principal ways in which the term 'freedom' is typically understood in political analysis, wiathi is properly understood by treating it on its own terms.


We describe a multimode fiber optic gyroscope. To compensate the distortions introduced along the propagation through the multimode fiber, a double phase conjugate mirror (DPCM) is inserted in the middle of the loop.


BACKGROUND: Complete cartilage loss and incomplete cartilage loss of the patella both have been reported to give good results with both resurfacing and nonresurfacing. We have tried to combine patellar denervation (PD) with the procedure and to compare the results of resurfacing or not resurfacing patella in posterior stabilized (PS) total knee arthroplasty (TKA). MATERIALS AND METHODS: A prospective single-center randomized prospective trial was done, including 68 patients undergoing unilateral TKA who were divided into patellar nonresurfacing (PNR) and patellar resurfacing (PR) groups. The patients underwent PS TKA. A blinded observer followed up the patients for 2 years, and visual analog scale at stairs (VAS-stairs), Knee Society Score (KSS), and range of motion were noted. RESULTS: The difference in VAS-stairs score from the baseline to the end of 1 month was significantly improved in the PR group, PNR = 4.4 ± 0.8 and PR = 5.5 ± 0.6, P = 0.0001. The difference in VAS-stairs score was significantly improved in the PR group again at 6 months, PNR = 5.9 ± 0.8 and PR = 7.1 ± 0.7, P = 0.0001. A comparison within the two groups at 1-month postop resulted in significantly better KSS 1 scores in the PR group (Chi-square value = 43.2, P < 0.001). When KSS 2 was compared between the two groups, we found no statistical significance in their preoperative scores and at postoperative time intervals of 1 month, 6 months, 1 year, and 2 years. CONCLUSIONS: Resurfacing patella with PD in an Outerbridge grade 4 patella yields better pain relief on stairs within the first 6 months. Also, resurfacing patella with PD in an Outerbridge grade 4 patella does not improve the functional outcomes at 2 years, and further long-term follow-up needs to be reported in the future.


Leadership for Rural Schools: Lessons For All Educators Edited by Donald M. Chalker,Ed.D. Technomic Publishing Co., Lancaster PA, 1999 ISBN 1-56676-695-8 Today, successful rural school leadership at all levels demands a sharp, intuitive master for handling the complex and politically laden organizational structure of a small district. Chalker et.al, highlight the many facets which commonly reverberate within and around a rural school atmosphere and that address the many avenues one must travel to remain effective as a school leader in a rural setting. The theme of "Leadership for Rural Schools" includes dynamics of leadership and highlights the methods and best practices to accomplish the tasks at hand. The text is organized into bite size, easily digestible nuggets of insights shared by multiple authors and prevalent in all rural school systems. The environmental culture and the climate of rural schools are expounded upon along with interesting stories that capture the essence of historical, legal, advice lending, and trend setting information relevant to practicing leadership in small town U.S.A. The chapters are laid out in a practical format with numerous citations to scholarly research and suggestions for professional practice throughout the book. Each chapter builds upon the next to provide a succinct, yet well documented approach to building community, political survival, curriculum and technology restructuring, and assessing overall quality. The book contains four independently interwoven sections of approximately four chapters each that collectively draw together the main themes of the text. The first of these four sections is entitled, "The Rural Setting" which characterizes the historical roots, images, values, demographic and economic conditions, and pros and cons of life in rural American schools. It provides a concise snapshot of the condition a rural school leaders must face in their ultimate challenge of seeking effective local school reform. Section Two labeled, "Rural Leadership: A View from the Top" combines vital political survival tips with details about pitfalls to avoid for all administrators, personnel, and school board members. It is at times witty and funny, yet packed with truth and consequences for school administrators. This section is a must read for all aspiring school personnel particularly for those who want to be superintendents and/or school board members. An overview of the human resources element along with applied techniques for accomplishing real school improvement for meeting instructional outcomes are also discussed. Next, is the section entitled, "Rural SiteBased Leadership" which focuses upon building internal and external relationships and creating organizational structures that work. These three chapters emphasize primarily the redefinition of rural leadership for the 90's and beyond. Significant highlights include delightful short stories reinforcing the impact effective communications and personal contact may have on "community building." Students are portrayed as a vital stakeholder link to overall school success and wise leaders must tap their potential and their collective input to steer a small district in a forward and positive direction. The final section of the book, "Leadership and Organizational Skills for Rural School Leaders," takes a hard, long look at incorporating technology into rural classrooms, seeking viable funding sources, and assessing the quality of such initiatives. …


The partial differential equations describing the deformation of an elastic body support a rich variety of waves (shock, shear, and torsion) as solutions. A scientific understanding of these wave solutions requires a mathematical analysis of the structure of the governing equations, combined with numerical computation of the solutions. When studying quasi-linear hyperbolic partial differential equations, whose solutions typically develop discontinuities, one must begin by writing the equations as a system of conservation laws. Assuming that there are n independent conserved quantities, the solution is specified by a vector U(X, t) that lies in an n-dimensional state space. The dynamical equations for u take the form ;+v *j(u)=0 (1.1)


Damage to the retina from diabetes can lead to permanent vision loss due to a condition known as diabetic retinopathy. In order to avoid this, it is essential to diagnose this disease early. To address these problems, this paper proposes a two-branch Grad-CAM attention-guided convolution neural network (AG-CNN) with initial CLAHE image preprocessing. The AG-CNN first builds a general attention to the entire image with the global branch, in order to further concentrate the system's attention on the localized areas of the problems, the system isolate the important regions (ROIs) of the global image and then feeds them to a local branch. This extensive experiment is based on the APTOS 2019 DR dataset. In order to start, we offer a solid global baseline that, using DenseNet-121 as a starting point, produced average accuracy/AUC values of 0.9746/0.995, respectively. The average accuracy and AUC of the AG-CNN are increased to 0.9848 and 0.998, respectively, after creating the local branch. which represents a new state-of-the-art in the field.


A knowledge of the rules of EC Competition is vital to those managers involved in businesses operating in the European Community. The regulations are far more encompassing than most managers suppose. Familiarity with the effects of Articles 85 and 86 will become increasingly relevant to the formulation of marketing and pricing strategies. This is particularly significant given that the Commission can impose fines of up to ten per cent of sales revenue or 1 million ECU for infringements. This article, based on the detailed research undertaken within one company, emphasises the ascending importance and pervasiveness of EC competition policy on those companies operating within the EC.


As a framework for data fusion, it is a source of information through a combination of appropriate methods to get a more satisfactory result, mainly detection, estimation of multiple sources of data, and the combination treatment. Because the measurement data from multiple sources always have some degree of uncertainty and inconsistency, using multi-source data fusion algorithm for the measurement data of multiple nodes for data fusion, using data redundancy to reduce this uncertainty, high reliability data. In this paper, the Bayesian estimation method is used to deal with multi-source data. It is proved by experiments that the algorithm is effective for the fusion of multi-source data and the inconsistency of the data.


Bhandul Island is a unique island of Arabian Sea located near the eastern coast of Karachi. An old community of native fisherman has been living in the island for many centuries. This island is located on northwest of the Indus Delta. A channel between this island and Karachi city provides a passage to the port Qasim located towards the north (Figure 1). It was a popular island in a time and occupied by a large number of fishermen with permanent settlements. Ibrahim Haidery is a nearest village located on western side of the island in Karachi. In the 1960s, the population of the area started moving. Now the entire island has been evacuated and its population has been moved to Ibrahim Haidery from where fishermen continue their fishing activities. There is a shrine of a religious saint in the island and large number of people annually come to the island to participate in the anniversary of the old saint. This area is environmentally as well as ecologically important because mangrove forests are found in this island. Siberian birds come each year in winter to this island. This area also provides home to 96 species of fishes as nursery and feeding ground (IUCN, 2005). Existence of mangroves for the sustainability and stability of the coast as well as for the island is necessary.1 This Island comes under the IUCN wetland protected list for Ramsar site. Eastern part of the Pakistan coast is also under the threat of rising sea level. Sea level rise rate in Karachi and surrounding areas is 1-2 millimeter per year.2 As the island is unique in its position having western side a big metropolitan city of Karachi and on eastern side the biggest wetland "Indus Delta" of country.3 Business tycoons keep their interest in developing a new city on the island, and on the other side, environmental stakeholders are continuously pushing to protect this island and keep this island a safe haven for natural habitat and biodiversity. It seems from the current and past records of aerial view that this island has not been in a stable position since many decades. That's why; it is constantly under the process of formation and deformation. It is because of natural processes, which have always been dominant over this island. The other reason is keeping this island secure from intense commercial activities.


Rice is one of the major staple foods consumed in Africa and its demand continues to increase as a result of population growth, urbanization and changing diets. Mangrove rice cultivation is of importance along the West-African Atlantic coast from Senegal and Gambia down to Guinea-Bissau, Guinea-Conakry, Sierra Leone and Liberia. Although mangrove rice productivity is low it contributes for a major share to the regional rice production. Sea-level rise and reduction in river discharges, caused by the effects of climate change, lead to salt-water intrusion and are a potential threat to the mangrove rice production and regional food security. Information about rice areas is crucial to provide informed decision and management with the aim of safeguarding and improving rice production in those areas. However, till date such information is very limited or unavailable at all. Therefore our goal in this study was to map out rice cultivated areas within the mangrove ecosystem stretching from Senegal to Liberia and to characterize those systems in terms of altitude and the rice phenology using secondary data and spatial analysis. We deployed off-season Landsat 8 Images, 30 meters SRTM Digital elevation data, derived vegetation indices (EVI, SAVI, Tasseled cap Index Wetness) and Google Earth data. Decision tree classification was then applied using the DEM and Tasseled Cap index on Wetness to delineate the Landsat data into uplands and mangrove lowlands. Then, supervised classification using the 'maximum likelihood' classifier was applied on the delineated mangrove lowlands to characterize the area into rice and non-rice. The classification result was validated with Google Earth images. The second stage in this work was to investigate the rice phenology using MODIS NDVI time series. Overall, the study shows the potency of using medium resolution satellite images like Landsat for characterizing mangrove rice growing environment.


ABSTRACT Public libraries are critical community facilities through which librarians support their communities before, during, and after natural disasters such as hurricanes. In their disaster responses, public librarians work to effectively restore library buildings, provide library materials, and, most critically, provide services that strengthen community resiliency and sense of safety. However, a neglected aspect of disaster policy and response is the lack of documentation regarding library transportation accessibility. In this study, the researchers used geographical information systems (GIS) approaches to investigate the extent to which public libraries are sited to serve vulnerable, rural populations in Northwest Florida. Results suggest that many public library branches are inopportunely sited relative to pockets of high-need populations, indicating that disaster services may need to be offered outside of the library building or transportation options be made available to residents of disaster-prone, inaccessible areas. The study's findings have the potential to inform library and information studies education, multidisciplinary research and policy-making, and to develop a public library disaster preparedness and response.


Borders are perhaps the most significant institutions in international relations. A massive literature demonstrates that border disputes fundamentally affect the character of relations between disputants, often escalating to violent and persistent conflict. However, the literature has barely begun to explore and identify the exact mechanisms that produce disputes and whereby these disputes escalate. Recent research demonstrates that how borders are drawn affects the probability of subsequent conflict and suggests that borders will be peaceful when they effectively and efficiently coordinate the actors on either side, thereby creating stable and predictable patterns of interactions. This research, however, ignores the obvious temporal component implied by theory. We develop the temporal component of an institutional theory of borders, starting from the argument that whether new international borders become more stable over time depends upon whether actors on both sides learn to coordinate on new jurisdictional international borders. We build on this idea to argue that the effect of time is significantly influenced by the manner in which the new border is drawn. We find that new borders that follow previous administrative frontiers become stable institutions much faster than than those drawn otherwise. In other words, stable and peaceful coordination on new borders occurs much faster when those new borders follow previous administrative frontiers.


Three methods of collection (freezing, acetone, and acetone: thioethanol: acetic acid) for human pituitary glands have been compared for optimal yields of luteinizing hormone (LH), adrenocorticotropin (ACTH) and growth hormone (GH). Yields of growth hormone from glands stored frozen (7–8 U/gland) were 3–4 times greater than by the other 2 methods, while for ACTH (pH 5) the yield (10.4 U/gland) was 7 times greater, and for LH (0.93 U/gland) this was almost twice that of the other collection methods. Length of storage time appeared to have an effect on GH yield; at an early time period (6 weeks) the differencesbetween collection methods were not as apparent as at 5 months. The differences in LH yields with the 3 collection methods were noted as early as 6 weeks, the shortest storage time studied. Thus, these studies, together with previously reported studies on TSH, indicate that 1) freezing of human pituitary glands following autopsy should be the collection method for optimal yields of pituitary hormones ...


This paper describes the design and implementation of an Efficient Architecture for Running THreads (EARTH) runtime system for a multi‐processor/multi‐node cluster. The (EARTH) model was designed to support the efficient execution of parallel (multi‐threaded) programs with irregular fine‐grain parallelism using off‐the‐shelf computers. Implementing an EARTH runtime system requires an explicitly threaded runtime system. For portability, we built this runtime system on top of Pthreads under Linux and used sockets for inter‐node communication. Moreover, in order to make the best use of the resources available on a cluster of symmetric multi‐processors (SMP), this implementation enables the overlapping of communication and computation.

Calcification is found infrequently in metastatic tumors. In hepatic metastases particularly it is generally considered as of rare occurrence, though the liver is a common site of secondary neoplastic growth. We have been able to find reports of only 8 cases in the literature (1–5). Experience has convinced us that the radiographic picture to be described herein is of practical value in the recognition of certain metastatic neoplasms in the liver, yielding a relatively specific diagnosis of tumor derived from the large bowel. Antemortem Radiographic Identification of Calcified Liver Metastases Within the last three years, one of us (A. J. M.) encountered 4 cases in which evidence of calcified liver metastases appeared in radiographs of the abdomen. In 3 of these, subsequent biopsy or autopsy confirmed the diagnosis. In each instance, the primary site of the neoplasm was in the large bowel. Case Reports Case I: W. D., a female forty-seven years old, was admitted to the medical service of the Norfolk Genera...


This study examined the associations of college students' attitudes toward women (feminism) and measures of "traditional family ideology," "authoritarian attitudes," and "religious fundamentalism" attitudes and beliefs. Data were collected from 377 college students selected with a stratified multistage sampling process from a rural university campus in middle Tennessee. Analyses of variance indicated a marked difference among the male and female students' feminism scores. In addition, students' age, religion, and their mothers' religion and education as well as the "traditional family ideology" and "authoritarian attitudes" scores were strongly related to students' attitudes toward women.

The importance and interest of determining the factor responsible for the dwarfism, iiif antilism, and other disabilities which appear spontaneously in a strain of mice, reared by one of us at Cold Spring Harbor, caused us to study iii this unique material the growth rate, the structure of the endocrine organs, and, later, to institute an endocrine therapy in an endeavor to determine physiologically the primary cause of the various disabilities present. These studies, which can now be reported upon in a preliminary paper, strongly indicate that the primary causal factor of the dwarfism and associated disabilities is an anterior-pituitary deficiency, for the endocrine disabilities simulate those displayed by hypophysectomized rats (Smith, '27, '30) and, as in the case of the hypophysectomized rats, daily implants of fresh anterior lobe bring these defective animals to a normal condition. By surgical removal of the anterior lobe of the pituitary in young rats and subsequent replacement therapy, it has been shown that the dwarfism and endocrine regression following the operation are directly due to the absence of pituitary secretions. The discovery, reported in this paper, that hereditary dwarfism in the mouse is associated with the absence of eosinophiles in the anterior lobe of the pituitary and with deficiencies of other endocrines closel? resembling


In quest for parametricization to optimize the efficiency of means-ends relations in performing commercial tasks, economy here implies the tendency to save any possible cognitive or linguistic efforts. Functioned as interactive means towards certain communication ends, advertising language, characterized by preferring acronyms or abbreviations, stereotypic sentence patterns and graphic symbols, is the epitome of sophisticated business philosophy. Pursuing the maximization of speech utility (the equilibrium of speech input and demands), cultural equivalentization in computational advertising, is highly supervised by the Language Economics to be quick and easy as conveying information to save scare time and effort while sustaining intelligibility simultaneously. The paper expounds parameter estimation of language economics in computational advertising on the lexical-syntactic level (vocabulary mismatch, query rewriting), and the textual level (contextual relevancy).


A selective, simple and efficient method-Reverse Phase High performance liquid chromatography with UV detector was developed for the determination of active alkaloid, namely strychnine in Homeopathic formulations. The RPHPLC separation was carried out using a Bischoff-chrombudget C18 (250mm x 4.6mm x5μm) column with a mobile phase consisting of Acetonitrile: Phosphate buffer pH3.6 with 0.2%TEA and 0.02% W/V SLS(55:45) hence providing high efficiency, high resolution and excellent peak shape for the analyte standard. The method was validated over the range of 1-6 μg/ml for strychnine. Accuracy is determined by parallel Spiking method instead of % recovery method because of very low concentration of an analyte in the formulations that can not be detected and %RSD was 1.9844. Interday precisions and Intraday precisions were within range. With a simple and minor sample preparation procedure and short run-time (<3 min), the proposed method was applicable for the quantitative analysis of strychnine in various homeopathic formulations.


BACKGROUND
The treatment of aortic root aneurysm remains challenging for both cardiac surgeon and cardiologist.

AIMS
The aim of this study was to assess and compare the long-term outcomes of different approaches to aortic root replacement (ARR).

METHODS
All elective patients operated for aortic root aneurysm with or without aortic regurgitation at our institution over 10-year period were included. We excluded the patients with any degree of aortic stenosis and with active endocarditis. We assessed mortality, freedom from reoperation, freedom from aortic valve regurgitation and the rate of hemorrhagic and thromboembolic complications.

RESULTS
Two hundred and four patients underwent elective aortic root replacement: 107 (53%) valve sparing aortic root replacement (VSARR), 35 (17%) mechanical Bentall procedure (MB) and 62 (30%) bioBentall procedure (BB). Early mortality for VSARR, BB and MB group was 2.8%, 4.8% and 0% (P = 0.40). Estimated 5-year survival was: 90.2% vs. 78.4% vs. 94.2% (P = 0.12), 5-year freedom from reoperation: 97.8%, 96.6%, and 96.8% (P = 0.99). Estimated 5-year freedom from complications was: 94.2%, 83.1% and 57.3% in the VSARR, BB and MB group respectively (P <0.001). On last follow up echocardiography 90.5%, 98.4% and 97.1% (P = 0.08) of patients were free from aortic regurgitation grade 2 or more. The median (IQR) aortic valve peak gradient was 9 (6-12) mm Hg, 12 (10-18) mm Hg and 16 (14-22) mmHg, respectively (P <0.001). Complications were predicted by mechanical Bentall (hazard ratio, 6.70 [2.54-17.63]; P <0.001).

CONCLUSION
With the same mortality, freedom from reoperation and minimal late complication rate in comparison with mechanical Bentall and bioBentall, VSARR might be the preferred approach to aortic root aneurysm.


The paper focuses on a hitherto unexplored area of research into the modern means of transport – the automobile and automotive issues in the field of theatre. The author has approached this area of problems from a developmental, historical and cultural-historical point of view. The basis consists of selected (surviving) theatre plays (including signs and posters) that appeared on stage in various forms and shapes from the end of the monarchy to the Second World War. The paper is based on a study of the library collections of the IDU (Institute of Theatre Arts) Library, the National Library and the database of the "Czech Amateur Theatre".


Effects of Coragen®, a ryanoid insecticide, applied topically to two crop-representative spiders, Enoplognatha ovata (Araneae: Theridiidae) and Tibellus spp. (Araneae: Philodromidae) Michael Samuel Tomascik Advisor: University of Guelph, 2015 Dr. J. Schmidt The role of spiders as natural enemies can be compromised by their susceptibility to broadspectrum insecticides. To date the toxic effects of Coragen® (a.i. Chlorantraniliprole) (DuPont Canada), a recently introduced ryanoid insecticide, have not been investigated in spiders. In this thesis, the direct lethal and sublethal effects of Coragen® applied topically to Enoplognatha ovata, and Tibellus spp., were determined. Coragen® applied at concentrations of 1.125 mg mL -1 (corresponding to the manufacturer recommended tank concentrations of 0.5 to 1.0 mg mL -1 ) caused mortality in >50% of the spiders tested. In arena tests sublethal concentrations did not affect the rate at which spiders killed Drosophila. The toxicity of Coragen® was enhanced by coapplication of piperonyl butoxide (PBO). These results suggest that differences between the ryanodine receptors of target pests and spiders are insufficient to result in selective toxicity and metabolic detoxification of Coragen® by spiders depends on oxidative and/or hydrolytic enzymes.

There exists ample research exploiting cognitive processes for robot localization and mapping, for instance RatSLAM [10]. In this regard, tasks such as visual perception and recognition, which are primarily governed by visual and perirhinal cortices, receive a little attention. To bridge this gap, we present a novel bio-inspired place recognition front-end for the RatSLAM system. Our algorithm uses Gist features to obtain the perceptual structure of the scenes and employs a modified growing self-organizing map (GSOM) to model the behavior of the cells found in perirhinal cortex, called recency and familiarity neurons [6]. This enables an online learning and recognition of the places without acquiring apriori knowledge of the environment. The experiments carried out on the standard St. Lucia dataset demonstrate that on average our approach achieves almost 10% improvement (in F1-Score); it is able to correctly flag the visited and unvisited places even for noisy and blurred visual inputs. The results show that the proposed method reaches fast convergence and utilizes a smaller number of cells (consumes less physical memory) to represent the traversed path compared to the RatSLAM approach.


Marcus Tullius Cicero is said to have referred to silence as "one of the great arts of conversation". A Roman statesman, lawyer and philosopher, Cicero hailed from a wealthy municipal family of the Roman equestrian order, and is considered to be one of Rome's greatest rhetoricians and stylists of prose. What exactly was Cicero onto? How could silence be so valuable in a society so beset with oration, with articulation, with proclamation, with pronouncement? And more to the purposes and theme of this special issue: what is, or what should be, the role of silence in the toolkit of the ethnographer? What might silence's role be in that of the teaching anthropologist? In this reflection, I think through some of the possible uses of silence in the anthropology classroom.


In this case, we describe a patient with visual field defect caused by non-ectatic/non- aneurysmatic arterial contact. A 29-year-old woman with no significant past medical history had noticed with the complaint of visual field loss in her right eye that started 2 years ago. Visual field examination showed partial visual field defects in the right eye. Radiologic examination has revealed a close relationship of right optic nerve with the first segment of anterior cerebral artery. However no typical space-occupying mass was revealed in the magnetic resonance imaging and no aneurysmal or ectatic arterial lesion was seen in the computed tomography angiography.


The purpose of this research is to 'know what causes the social isolation felt by marriage immigrant women'. Thus, a total of 253 cases of marriage immigrant women who use Multi-cultural Family Support Center in D city have been analyzed. The findings reveal that the factors influencing the sense of isolation in the social environment, experienced by immigrant women married to Koreans are: social support, family relationships, self-esteem, household income and economic activity. In other words, their strong sense of isolation from society will be lessened when they get more social support, are happy with their family relationships, have their improved self-esteem, earn higher household incomes and don't take part in undesirable economic activities. Based on the research results, this study makes suggestions, on both a political and practical level, to solve the above problem of social isolation faced by marriage immigrant women through their financial stability, desirable economic activities, healthy family relationships, the enhancement of self-esteem and the provision of generous social support for them. ■ keyword :∣Marriage Immigrant Women∣Social Isolation∣Self-esteem∣Satisfied with Family Relationships ∣Social Support∣ 접수일자 : 2020년 06월 24일 수정일자 : 2020년 07월 23일 심사완료일 : 2020년 07월 23일 교신저자 : 정혜원, e-mail : email@example.com 한국콘텐츠학회논문지 '20 Vol. 20 No. 9 590


Simple Summary The body is dependent on nutrients and ions to work normally. Within the hu-man body there is a group of proteins named transporters or solute carriers. These transporters are vital for the transport of nutrients such as glucose, amino acids, and fats, as well as ions such as sodium, calcium, and potassium. Despite being vital for normal physiology, as well as pathophysiology, a large number (approximately one third) of the transporters are orphans, where information about their expression and function is missing. Here, we aimed to begin to unravel the expression and function of one of these orphan transporters, MFSD11, by studying its orthologue in fruit flies (CG18549). We found that the fly orthologue is expressed in the brain of fruit flies and that it is possibly involved in metabolism and/or locomotion of the flies. The exact mechanism behind the observed behaviors is not fully understood, but our study provides new insights into the expression and function of CG18549. Clearly, these results, among others about the orphan transporters, provide a strong example as to why it is vital to fully characterize them and through that gain knowledge about the body during normal condition and disease. Abstract Cellular transport and function are dependent on substrate influx and efflux of various compounds. In humans, the largest superfamily of transporters is the SoLute Carriers (SLCs). Many transporters are orphans and little to nothing is known about their expression and/or function, yet they have been assigned to a cluster called atypical SLCs. One of these atypical SLCs is MFSD11. Here we present a first in-depth characterization of the MFSD11, CG18549. By gene expression and behavior analysis on ubiquitous and brain-specific knockdown flies. CG18549 knockdown flies were found to have altered adipokinetic hormone and adipokinteic hormone receptor expression as well as reduced vesicular monoamine transporter expression; to exhibit an altered locomotor behavior, and to have an altered reaction to stress stimuli. Furthermore, the gene expression of CG18549 in the brain was visualized and abundant expression in both the larvae and adult brain was observed, a result that is coherent with the FlyAtlas Anatomy microarray. The exact mechanism behind the observed behaviors is not fully understood, but this study provides new insights into the expression and function of CG18549. Clearly, these results provide a strong example as to why it is vital to fully characterize orphan transporters and through that gain knowledge about the body during normal condition and disease.


Acute appendicitis is one of the most common causes of acute abdominal pain and is one of the most common surgical abdominal emergencies. Nowadays, patients with acute appendicitis are managed in most cases with laparoscopic appendectomy, which is usually performed through three small skin incisions and three trocars [1]. In the past, conventional open appendectomy was the treatment of choice and was the gold standard of treatment for patients with acute appendicitis. In open appendectomy, a small skin incision in the right inferior abdominal quadrant over BcBurney point was performed and the appendix was removed through a relatively small wound. An abdominal drain was rarely used after open appendectomy. Certain studies suggested increased intra-abdominal abscess rates following laparoscopic appendectomy, especially for perforated appendicitis, because of this drainage of the abdominal cavity is more common after laparoscopic appendectomy [2]. The routine use of abdominal drain after laparoscopic appendectomy is still under debate.


In the content-based retrieval,the conventional approach to the retrieval algorithms is to conduct the feature extraction and similarity match on the basis of single feature and then to conduct multi-feature extraction under the condition of weighting the result of single feature extraction.Such an approach incurs large amount of calculation and lacks flexibility.Therefore,a new architecture to organize different retrieval algorithms in content-based retrieval is proposed.It appears as a hierarchical architecture,which is able to acquire a gradually accurate result.The transfer factor,priority factor and complexity factor are defined in this architecture,which can help to combine different feature-oriented retrieval algorithms flexibly.Experiment shows that this architecture improves the retrieval efficiency,resulting in a reduction of 40% of the retrieval time.
