Cardiac surgery, and especially cardiopulmonary bypass (CPB), has been the poster child for postoperative cognitive morbidity. Over the past 10-15 years, however, it has become increasingly clear that disruption or decline in cognitive function is also fairly widespread among elderly non-cardiac surgical patients. The reasons are a matter of considerable controversy and this brief overview will recap current perspectives on the problem.

OA, a 35-year-old man was admitted to the University of Nigeria Teaching Hospital at Enugu by one of us (MACA). The complaint was that of neck swelling for 1 month with associated difficulty in breathing. Distended superficial veins were noted as well as tracheal deviation. Surgical biopsy was undertaken, while the tissue was submitted to the coauthor (WIBO). The specimen was received as a 1.8x1.2x0.8cm pale firm mass. On microscopy, thyroid tissue was scarcely apparent on account of sheets of small, round, hyperchromatic, tumor cells of the lymphoid series. Neither giant cell formation nor the starry-sky picture was evident. Non-Hodgkin's lymphoma was diagnosed firmly Figure 1.


Marine sediments on continental margins contain varying proportions of marine and terrestrial components. On the slope and rise of several ocean margins, pollen and spores of vascular plants from adjacent continents form an important component of present and past sedimentary records (Heusser, 1978). Brought to the offshore environment primarily by streams, pollen in marine sediments reflects the composition of vegetation in coastal drainage basins, as well as the effects of fluviomarine sedimentation (Cross, Thompson, and Zaitzeff, 1966; Stanley, 1969). The basic distribution patterns of present vegetation of the Pacific coast of North America are controlled by climate (Wolfe, 1979). The maritime climate of coastal California is determined largely by the zonal circulation over the Pacific Ocean and the northwest-southeasttrending Coast Ranges (Major, 1977). The Mediterranean-type climate of cismontane southern California— long, warm, dry summers with mild, wet winters—is moderated by coastal fog and characterized by relatively small annual changes in temperature and precipitation. In the Santa Barbara region, for example, rainfall averages 300 to 500 mm/yr and annual temperature ranges from 11°C to 20°C (Elford, 1974). Coastal vegetation—salt marsh and sagebrush—is composed of broad-leaved sclerophylls and herbs. Characteristic genera are A triplex (saltbush), Salicornia (glasswort), and Artemisia (sagebrush). Chaparral consisting of woody shrubs such as Cercocarpus (mountain mahogany), Adenostoma (chamise), and Rhus (sumac) is best developed at elevations up to 300 meters. At higher elevations with increased rainfall, woodland of southern oak forest occurs; above 1,500 meters, mixed hardwood forest with coniferous vegetation including species of Pinus (pine) appears (Munz, 1974). Areas south of 33 °N latitude coastal California and Baja California, Mexico, have a variant of hot-desert-type climate; however, desert vegetation typified by Larrea divaricata (creosote bush) is not dominant until about 30°N latitude (Major, 1977; Leopold, 1950). As in cismontane California to the north, coastal strand vegetation and chaparral are replaced by pine-oak forest at higher elevations. On the semi-arid southernmost tip of Baja California, tropical deciduous forest is present in which species of Bursera (elephant tree) are locally common.

Abstract In an optimal processes control, where the considered goals are in general observed as concurrently conflicted, a multi-objective approach fits the best. Commonly used scalarization techniques in multi-objective optimization need a transformation of the individual single-objective functions involved into a scalar multi-criteria objective function. There are many parameters which can influence the optimization results solutions, including an unreachable utopia point value. In this study, the authors compare the multi-objective problem solutions found via two ways of the individual objectives transformation with the respect to setting the utopia point. The methods are used in the area of production control in a case study for a batch production system. To find the solutions, The Weighted Sum Method with a priori articulated preferences under specific constraints as the scalar multi-objective optimization method is applied in simulation optimization.


This thesis is aimed at analyzing meaning construal of the review texts of "Songs of the Sea" show in Sentosa Island, Singapore, on March 2013 which was written by the people who were watching this show. The data of this study was taken from the internet, especially from a travel site www.tripadvisor.com. To analyze this study, the researcher uses the framework of M.A.K. Halliday and Matthiessen (1999) and uses descriptive qualitative method. The result showed that there are 24 simple sentences mostly found in the data because the people don't matter the structure when writing. There are four types of figures and figures of being are the most dominant in the review texts because the people frequently described about the show, how's the people's enthusiasm, and the atmosphere of situation and condition in Sentosa Island, Singapore. As stated before, figures of being mostly dominate the data, automatically relational process also dominates the data with participant roles, token and value. Then, type of circumstances mostly dominate in the data is circumstance of manner (quality) because all the people commented about the quality of the show. The realization of participants mostly exist is simplethings (conscious) because the people often told about themselves when they visited that show, the realization of process mostly exist in the data is polar: non-phasal verbs in present tense because most of people often applied non-phasal verbs in their writing and they also often described what "Songs of the Sea" is like so that tenses which was frequently used is present tense, meanwhile for the realization of circumstance mostly existed in the data is macro circumstances because in the data is found so many circumstances which have more than one word. Based on the framework used by the researcher, it really proves that the review texts actually show that relationalprocess most contributed in the community review of "Songs of the Sea.


Single atom catalysts (SAC) are highly desirable to maximize atom efficiency, while fabricating them is largely dependent on choosing a suitable substrate to effectually fasten them. Here, in terms of strong metal–metal interaction, first-principle calculations have been performed to study the possibility of monolayer polymeric transition metal–phthalocyanines (TM–Pcs, M from Sc to Zn) as the substrate in an effect to obtain evenly distributed single Pt atom catalyst. We found that Ti–Pc is the most appropriate compound by virtue of high binding strength of Pt/Ti–Pc system and high diffusion energy barrier of Pt catalyst atom, which jointly prevent the formation of Pt clusters. CO oxidation on Pt/Ti–Pc presents some unexpected behaviors, where a presorbed CO (pCO) molecule could activate the catalyst and reduce the reaction barrier. Examining the electronic structure evolution in the reaction process demonstrates that the presence of a pCO promotes O2 adsorption and activation. Our results demonstrate tha...


We characterize supramenable groups in terms of the existence of invariant probability measures for partial actions on compact Hausdorff spaces and the existence of tracial states on partial crossed products. These characterizations show that, in general, one cannot decompose a partial crossed product of a $\text{C}^{\ast }$ -algebra by a semidirect product of groups into two iterated partial crossed products. However, we give conditions which ensure that such decomposition is possible.


Abstract As a possible step to evaluate the role of tumor promoters in normal cells, the effects of phorbol and its ester, 12-O-tetradecanoyl-phorbol-13-acetate (TPA), on normal mammary gland function and pituitary secretion of growth hormone (GH) and prolactin, were examined in lactating C3H/He mice. Daily subcutaneous injections of 400 μg phorbol or 4 μg TPA during Days 12 and 14 of lactation resulted in a significant decline in litter growth rate and the ratio of RNA synthesis: DNA synthesis of mammary glands associated with an increase in mammary gland DNA synthesis. On the other hand, pituitary synthesis and release of GH and prolactin, the pattern of estrous cycles and ovarian structures were affected little by these treatments. All findings strongly suggest that these tumor promoters can directly inhibit lactation by shifting mammary gland cells from a functional state to a mitotic state.


1 Professor, General Medicine, Indira Gandhi Medical College, Shimla, HP 2 Junior Resident, General Medicine, Indira Gandhi Medical College, Shimla, HP 3 Junior Resident, Pediatrics, Indira Gandhi Medical College, Shimla, HP *Corresponding Author Dr Swati Mahajan Senior Resident, Department of Medicine, DRRPGMC Tanda at Kangra Pin 176001, India Abstract Introduction: The Human Immunodeficiency Virus (HIV) is a lentivirus (subgroup of retrovirus) that causes HIV infection and over time Acquired Immunodeficiency Syndrome (AIDS). HIV causes progressive impairment in body's immune system leading to increased susceptibility to fatal opportunistic infections known as acquired immune-deficiency syndrome (AIDS). The aim of our study was to study the clinical profile of HIV infected patients. Materials: It was an observational study including 127 HIV positive patients in a tertiary health care centre. According to the WHO case definition, HIV in adults and children 18 months or older is diagnosed based on positive HIV antibody testing (rapid or laboratory-based enzyme immunoassay).This is confirmed by a second HIV antibody test (rapid or laboratory-based enzyme immunoassay) and/or; positive virological test for HIV or its components (HIV-RNA or HIV-DNA or ultrasensitive HIV p24 antigen) confirmed by a second virological test obtained from a separate determination. Observations: In our study, out of the 127 HIV/AIDS patients, majority 54(42.52%) belonged to 31-40 years of age group, 71(55.9%) were males, married patients were 121 (95.28%), less educated group had majority with maximum among the group educated till 12th standard (53.54%), majority of male subjects were drivers by profession(39.44%) and females were housewives(80.36%).Majority 44(34.64%) had CD4 count between 251-500. Conclusion: The present study found that most of the HIV infected patients were from sexually active age group. The commonest mode of acquiring infection was heterosexual contact, emphasizing the need to strengthen our Information education and communication (IEC) strategies to contain HIV/AIDS. Keyword: HIV, AIDS.


: Benzoic acids with suitable substituents bearing phenyl ring in the ortho position undergo cyclization by intramolecular Friedel-Crafts acylation in the presence of Nafion-H, a perfluorinated resinsulfonic acid catalyst. Synthesis of anthraquinone, anthrone, fluorenone, a -tetralone, 1-benzosuberone and heterocycles such as acridone, xanthone etc. is easily achieved in good to excellent yields (82-95%) by this method.


INTRODUCTION Benzene is among the most commonly known aromatic hydrocarbons, which is a colorless, liquid, and volatile substance with a sweet odor. Among the derivatives of benzene are toluene, xylene, acetone, ether, styrene, aniline, and hexane. Due to its volatility, benzene can be inhaled in environments with poor ventilation. In the industry, benzene is used in the adhesives for manufacturing leather goods and carton boxes, in cleaning metal tools, for dissolving paints and cleaning parts in printing, and for dissolving and diluting paints in car body and paint shops.[1]


SUMMARY The first two articles in this series have shown the direction of travel for health and social care in England, and how the status quo in already stressed systems is not viable. It is difficult to disagree with the principles of 'integrated care', yet we currently lack evidenced models on which we might build. There is a need for experiential learning and sharing of experiences. This third article describes in more granularity the experiences, positive and negative, of an early-adopting integrating service in south-east London that incorporated aspects of the local authority and secondary care physical and mental health services. It provides structured guidance on which types of integration one might aim for, managing internal and external relationships, and discussion on evaluating progress.


Background: Complication rates reported for contemporary knee reconstruction limb salvage surgery (LSS), an alternative to amputation patients with bone tumours of the proximal tibia and distal femur, have not been extensively explored in China. Objective: Functional outcomes, survival, prosthesis failure, and complication rates were investigated in Chinese patients with malignant or aggressive tumours of the knee joint. Methods: A retrospective study was conducted of 47 patients with knee joint tumours (M:F, 23:24; mean age 27±6 years; range 15 to 39 years) treated with preand post-operative chemotherapy combined with extensive tumour resection and metal prosthesis replacement. Patients were followed from March 1998 to March 2008, until death or limb salvage failure. LSS efficacy, survival, prosthetic failure, and complications were evaluated by Musculoskeletal Tumour Society (MSTS) scoring. Results: Patients were followed up for a median of 89 months. Mean operative bleeding and surgical time were 600±154 (300-1500) mL and 2.8±0.6 (1.5-3.5), respectively. No early infections were reported; however, 8 (17.0%) and 3 (6.3%) patients developed superficial infections or deep tissue infections, respectively, and 9 (19.1%) developed deep vein thrombosis. Prosthetic loosening, breakage, and removal was reported in 7 (14.9%), 2 (4.3%), and 3 (6.3%) patients, respectively. Only 1 (2.1%) patient required subsequent amputation. A total of 12 (25.5%) developed recurrence, and 23 (48.9%) died during the follow-up time. Mean MSTS was 78±12%. Conclusions: Combined chemotherapy, extensive resection, and metal prosthesis reconstruction optimized functional recovery. However, potentially life-threatening complications, infections, and recurrence limited its broad implementation.


Abstract The effects of a number of mineral dusts, administered by intratracheal instillation, on the rat lung have been investigated. Firstly, the acute response to 0.5 mg of quartz and bentonite was followed up to 7 days after instillation. The numbers and types of cells recovered and the amounts of 'free' LDH and protein in the lavage fluid were measured. Even at such low doses, it was possible to detect and quantify changes in these parameters. Secondly, the effects of 5 mg of quartz up to 100 days after instillation were compared with the effects of 5 mg of two reputedly non-fibrogenic dusts, bentonite and TiO 2 . Measurements of 'free' peroxidase and lysozyme were also included. The most marked difference between the dusts was the prolonged infiltration of PMN into the lung in the presence of quartz. This may implicate a role for these cells in the pathogenesis of pulmonary fibrosis.


Mobile devices are increasingly being incorporated onto Picture Archiving and Communication Systems (PACS). Previous work on medical image access using mobile devices essentially focuses on enabling the visualization of the medical images at the mobile devices. In contrast, we propose and develop a distributed system that allows medical image analysis using mobile devices. As a proof-of-concept, based on our distributed system, we develop a tool for dental implant simulation using mobile devices. We also discuss the perspectives of extending the current system to incorporate Computer Aided Diagnosis (CAD) algorithms in it.


The authors began a study in 2008 (Glenn, 2008) investigating the impact that different inlet and outlet configurations of stormwater ponds may have on short-circuiting potential. The study team created several theoretical ponds with varying inlet and outlet locations using the Surface Water Modeling System (SMS) and RMA2 and ran hydraulic simulations to investigate the unique flow patterns within the ponds. Short-circuiting in a pond is dependent upon the time and distance traveled by the flow of water from the inlet to the outlet. The team traced the flow paths and velocities of massless particles for each simulation to determine the pond configuration that most effectively prevented short-circuiting. Subsequently, the study has been expanded to include varying inflows and pond volumes. For each configuration, the team determined a dimensionless quantity, the Short-Circuiting Index (SCI) that is based on the detention time, pond geometry and inflow and was used to assess each pond's potential for short-circuiting. The results are compared with a different methodology, the Flow Path Ratio (FPR) that is based on the relative distance between the pond inlet and outlet and was developed by the Florida Department of Environmental Protection and Water Management Districts (Department, 2009).


As the field of metagenomics and microbiome continue to growth at an unprecedented rate, the need for proper controls is paramount to ascertain "truth". Property designed microbiome experiments should include a minimum of three types of controls; positive controls, and two types of negative controls; trip blank negatives and laboratory processing controls and, as with all scientific experiments, more controls can help pinpoint all system bias which ultimately contribute to valid results. In recent years, a variety of gDNA microbial reference controls have been developed, but deficits still remain, including proper intact whole cell microbial standards to account for DNA extraction bias as well as certified DNA-free reagents to support a "perfect" negative control. Since negative controls are critical, and must be included with all experiments, they should include samples such as trip blanks, reagents blanks, process blanks, which all help control for the "extraterrestrial" DNA found in samples that are unrelated to the sample itself also known as the "Kitome". The "Kitome" is the contaminating DNA of kits and reagents used to extract the DNA and synthesize the library. These DNA contribute to the final results and must be circumvented to obtain proper results.


Image classification is a technique to categorize an image in to given classes on the basis of hidden characteristics or features extracted using image processing. With rapidly growing technology, the size of images is growing. Different categories of images may contain different types of hidden information such as x-ray, CT scan, MRI, pathologies images, remote sensing images, satellite images, and natural scene image captured via digital cameras. In this chapter, the authors have surveyed various articles and books and summarized image classification techniques. There are supervised techniques like KNN and SVM, which classify an image into given classes and unsupervised techniques like K-means and ISODATA for classifying image into a group of clusters. For big images, deep learning networks can be employed that are fast and efficient and also compute hidden features automatically.


Nanomaterials
Using adhesive tape to pull off monolayers of two-dimensional (2D) materials is now a well-established approach. However, the flakes tend to be micrometer scale, and the creation of multilayer stacks for device application can be challenging and time consuming. Shim et al. show that monolayers of a variety of 2D materials, including molybdenum disulfide and hexagonal boron nitride, can be cleaved from multilayers grown as 5-centimeter-diameter wafers. The multilayer is capped with a nickel layer, which can be used to pull off the entire grown stack. The bottom of the stack is again capped with nickel, and a second round of cleaving leaves the monolayer on the bottom nickel layer. The monolayers could be transferred to other surfaces, which allowed the authors to make field-effect transistors with high charge-carrier mobilities.

the ajterial pressure, and a drop in body temperature is beneficial in reducing the general metabolism to a level more adapted to the reduced oxygen-carrying capacity of the blood. The "shock-cradle " can be a shock producer. Patients expend their ebbing strength in trying to throw it off, and in this demonstrate that the physiological call of instinct is wiser than the teaching of the textbooks. Morphine must be used with great caution. No more than i gr. (16 mg.) should be given at a time, and it should be given into a vein, since in a state of shock it is absorbed slowly from the subcutaneous tissues. A second and larger subcutaneous dose is apt to be given if the first fails, and when later the circulation is restored the accumulated amount is absorbed and may produce a profound stupor. The use of pressor drugs, including the adrenal preparations, is unwise. They may do good in primary shock accompanied by vasodilatation, but here they are unnecessary. In oligaemic shock, which is associated with vasoconstriction, the real need is for an increased supply of blood and oxygen to the tissues rather than for a raised systolic pressure, and further vasoconstriction may therefore do more harm than good.


Substituted 4-hydroxy-1,3-dioxanes II react rapidly with PO(NCS) 3 to give 4-isothiocyanato-1,3-dioxanes III . The 1 H NMR spectra showed that in the isothiocyanate IIIa the predominant stereoisomer has its NCS group in axial position. The addition of benzylamine to the isothiocyanates IIIa and IIIb gave uniform thioureas IVa and IVb with equatorial alkyl groups at 2 and 6 positions and axial thioureido group at 4 position. On the other hand, the isothiocyanate IIIc reacts with benzylamine to give a mixture of three stereoisomeric thioureas V,VI , and VIII . The structure of VI was proved by means of X-ray diffraction analysis; in crystalline form the molecules of VI are present as H-bonded dimers (N-H ... O).


This chapter discusses one of the major problems currently pending in connection with the Libyan claims settlement agreement and the Foreign Claims Settlement Commissions' work in this area. It discusses foreign affairs litigation that is right now a very real confrontation between two major governments, in this instance the United States and France. Way back in 1966, instead of denouncing the 1929 Warsaw Convention and its very low limits of liability for personal injury and death, the U.S. government succeeded in getting the airlines of the world voluntarily to very substantially raise their limits of liability and to adopt absolute liability as the basis for liability. In the course of the litigation before Judge Hogan, Libya brought a motion to dismiss based on several grounds but principally on the ground that the Foreign Sovereign immunities Act (FSIA) allowed suits only by "natural persons who are nationals of the United States".

Moisturizer is one of cosmetics used for dry skin care and can make skin become moist and soft. Natural material can be used to maintain water content in the skin and soften skin is Aloe vera. Aloe vera contains minerals, vitamins A, C, E and B12. In addition to Aloe vera to maintain antioxidants in the skin is green grass jelly because it has flavonoid content. Content contained in Aloe vera and green grass jelly can be used for making natural moisturizers because at this time many moisturizers that contain harmful chemicals. This observation was to analyze differences in concentration of Aloe vera and green grass jelly on moisturizers and analyze antioxidant activity of green grass jelly. Method used in making this moisturizer is mixing with green grass jelly formulation (2.5%; 5%; 7.5%) + Aloe vera (2.5%, 5%, 7.5%, 10%), and non-sample formulation treatment. Analysis of this experimental data was qualitative on moisturizers and quantitatively to calculate levels of flavonoids in green grass jelly. Results of this study indicate that difference in concentration of Aloe vera + green grass jelly greatly affects parameters of good moisturizer used, and greater addition of green grass jelly concentration greater flavonoid content in moisturizer.


A series of Ba2SiO4∶Eu2+ green phosphors have been synthesized by high temperature solid state method.The effects of different fluxes on the crystal structure,surface morphology and spectral characteristics of Ba2SiO4∶Eu2+ phosphors were systematically investigated by X-ray powder diffraction(XRD),scanning electron microscopy(SEM) and fluorescence spectrophotometer.The function mechanism of different fluxes on the preparation of Ba2SiO4∶Eu2+ phosphors have also been discussed.XRD results show that the Ba2SiO4∶Eu2+ phosphor without flux has the impurity phase of BaSi2 and SiO2 during firing,while fritted with NH4F,Na2CO3 or H3BO3 flux,the impurity phase of BaSi2 can be suppressed.BaF2 flux can get the pure orthorhombic.By comparing the influence of different fluxes on the emission of Eu2+,it was found that the emission intensity of the Ba2SiO4∶Eu2+ phosphor with 2% mass fraction of BaF2,NH4F or Na2CO3 flux improved by 138%,81%,34% than that of the powder without the flux material,while the luminescent intensity reduced 14% when using 2% mass fraction of H3BO3 as flux.The phosphor powders were spherical-like shapes using BaF2 as the flux,while the phosphor powder prepared with NH4F,Na2CO3 or H3BO3 as flux had the irregular laminated structure,spindle shape and irregular polygon,respectively.


Phialocephala scopiformis Kowalski & Kehr is a foliar fungal endophyte of white spruce (Picea glauca (Moench) Voss) that produces the anti-insect compound rugulosin and other compounds in lower amounts. Seedlings inoculated with this and other toxigenic endophytes have increased tolerance to the spruce budworm Choristoneura fumiferana (Clemens, 1865). The presence of rugulosin in the diet and in needles infected by P. scopiformis reduces the growth rate of the insect. One of 300 white spruce trees inoculated as a seedling in 2001 was chosen to investigate the distribution of P. scopiformis and its principal toxin rugulosin throughout the crown. To facilitate the detection of the fungus in small samples, a qPCR assay was developed based on the ITS region of fungal ribosomal DNA targeting a genetic polymorphism unique to P. scopiformis. The assay was specific, with a method limit of detection 100 ng mycelium per gram needle sample with high reproducibility and accuracy. We found that 11 years after inoculat...


This paper studies the information content of options net order flows and its effect on stock returns. The order flows are separated in customer-initiated (retail or institution) and firm initiated (proprietary desks of institutions) orders. These two types of order flows are negatively correlated and predict stock returns with opposite signs. Customer-initiated net trading volume is largely driven by positive information about underlying and positively predicts stock returns. Firm order flows recognize both future positive and negative news, supply liquidity to overoptimistic customer order flows, largely short-sell underlying stocks in the options market, and negatively predict stock returns. There is also a clientele effect: customer order flows prefer long options positions to short positions, and trade more in call options; firm order flows prefer short options positions and trade in both, calls and puts.

Soil insecticides were applied at planting time at 4 locations in IL: 8 May (Urbana), 11 May (Bloomington), 17 May (Monmouth), and 24 May (DeKalb). The experimental design was a randomized complete block with 4 replications. Each treatment was applied to a single 100-ft row; rows were 30 inches apart. Granular insecticides were metered through Noble units mounted on each of the planter units (John Deere, 7000 series, 4-row max-emergence planter). Granules were applied in-furrow or in a 7-inch band ahead of the firming wheels and incorporated into the soil. Liquid application of Brace was delivered at planting in a 7- to 10-inch band with an even flat fan nozzle (Teejet 8004E) mounted ahead of the firming wheels and turned perpendicular to the row for band applications. Later, the liquid was incorporated into the soil. The liquid was applied with a compressed-air system calibrated to deliver 42.4 gal/acre at 30 psi at a speed of 5 mph. Five roots were evaluated for damage in each plot using the Iowa 1-6 scale. Stand counts were determined by recording the number of plants per 17.4 row ft.


It is well known that many subjects who survived a suicide attempt will make further suicide attempts, even after the medical treatment at critical emergency unit. To examine the effectiveness of continuous follow-up care by case manager after the suicide attempt, a randomized, controlled, multicenter trial by J-MISP (Japanese Multimodal Intervention Trials for Suicide Prevention) has been launched in 2005. This research project is one of the strategic research projects funded by The Japanese Ministry of Health, Labour and Welfare. In this study, J-MISP will implement the intervention for suicide attempters, a considerably high-risk group of further suicide attempts, who are transported by emergency services. After a brief psychoeducation, the study subjects will be randomly assigned to continuous case management group or standard care group as a control. The subjects will be followed up for 1.5 to 3.5 years. The primary outcome measure is the reduction of the number of further suicide. Suicide ideation, depressive symptoms, and general health condition will be also evaluated as secondary measures. We hope that the results of this trial will help to develop effective strategies to prevent further suicide attempts in Japan. Language: en


Introduction. Neuroendocrine differentiation in colorectal cancer is reportedly associated with poorer grade of tumor differentiation, nodal and distant metastasis, and other unfavorable features, contributing to a worse clinical outcome. Colorectal cancer with osteoclast-like giant cells (OGCs) is extremely rare. Case Presentation. An 86-year-old woman was diagnosed as double cancer of the transverse and sigmoid colon. Both tumors were simultaneously removed. The transverse colon cancer directly invaded the area of the right gastroepiploic vessels and spread to the nodes and histologically consisted of both the tubuloglandular and solid components. CD8/granzyme B-positive tumor-infiltrating lymphocytes and CD163/CD68-positive macrophages, frequently forming OGCs, were observed particularly at the invasion front. The carcinoma cells were labeled focally for synaptophysin and diffusely for the DR locus of the human leukocyte antigen and programmed death-ligand 1 (PD-L1). Deficient expression of DNA mismatch repair (dMMR) proteins was immunohistochemically confirmed. The patient died 16 months after surgery. Conclusion.

2020 marks an important year in the evolution of BioTM. We received our first impact factor of 6.091 this year. This is a massive accomplishment for all stakeholders of the journal. The journal was formally launched in 2015 and we published our first issue in 2016. Within a short period of 4 years, we were able to reach this significant milestone. Huge thanks to all BioTM authors who trusted the journal with their precious manuscripts in the early, unproven days. Submission of high-quality manuscripts is the principal reason that led to an impressive launching impact factor. BioTM welcomes manuscripts in all aspects of bioengineering including drug delivery, drug discovery and development, tissue engineering, synthetic biology, biosensors, organoids and organ-mimetic systems, stem cell therapies, gene therapies, immunotherapies, patient-targeted therapies, medical devices, regenerative medicine, implant/patient interface, computational modeling, and bioinformatics. Areas including drug delivery, gene therapy, sirRNA delivery, regenerative medicine, nanomedicine, biomedical devices, and cell therapy have been particularly well represented in the manuscripts recently submitted to BioTM. This is expected because these fields represent some of the most active research areas at the interface of medicine and engineering, especially those that focus on developing/ testing novel materials or devices, for example, nanoparticles and microneedles for drug delivery. Indeed, some of the recent BioTM papers in drug delivery have focused on the use of microneedles for vaccine delivery. These papers demonstrated novel microneedle designs, for example, self-healing microneedles for encapsulation, as well as translational studies to nonhuman primate studies for hepatitis B vaccine. Along the same general theme, studies on ocular drug delivery devices were also featured prominently. The studies described novel designs of protein-delivery systems as well as studies in nonhuman primates demonstrating long-lasting release of proteins in the eye. Collectively, the reports along the translational axis of drug delivery devices represent a growing need in the field, and we are delighted to see those represent in our issues. On a more fundamental side, microfluidic devices leading to model systems for blood–brain barrier were also described. Such devices are playing an increasing role in in vitro optimization and acceleration of drug development timescales. Tissue engineering was also a commonly discussed subject in recent BioTM papers, also consistent with the large community of researchers working at the interface of engineering and regenerative medicine. Covered tissue engineering topics included engineering of hydrogel and decellularized matrices and generation of tissue-specific blood vessels. Polymeric materials of various forms were discussed, including composite materials, hydrogels, and capsules. These reports represent the great activity of research focused on understanding the design features of polymeric materials, polymer-tissue interface, as well as in vivo assessment of their biological functions. Consistent with general literature trends, a significant number of recent papers were focused on nanomedicine. Topics included translatable mouse models for cancer, new designs of nanoparticles, and scalable synthesis methods for nanoparticles. Translationally focused reports, for example, novel tumor models for nanomedicine and scalable synthesis methods, represent a particular need of time and we look forward to receiving more similar translationally focused nanomedicine manuscripts in future. Studies demonstrating novel applications of nanoparticles were also featured prominently in our recent publications, including the use of nanoparticles for improved residence of sunscreens on the skin and siRNA delivery for applications in lymphoma and wound healing. Papers on medical devices included control algorithms for artificial pancreas. Along with original research articles, we also published reviews on some of the active current topics in translational medicine including ionic liquids for biomedical applications, clinical landscape of nanomedicine, and translational status of nanocrystals. Reviews in BioTM are particularly focused on reporting translational advances and hurdles in the field. We are thankful for the strong support from our editorial board members. In 2020, we added six new editorial board members: Jennifer West (Duke, University), Xiaoyuan Chen (NIH), David Mooney (Harvard University), Molly Stevens (Imperial College, London), Maria Jose Alonso (University of Santiago de Compostela, Spain), and Andreas Lendlein (Helmholtz Institute of Biomaterial Science, Germany). We look to our board for guidance and vision. We are especially thankful to the board members for routinely publishing their own research in BioTM. We feature one board member in each issue. You can read these biographies at https://aiche.onlinelibrary.wiley.com/journal/hub/ journal/23806761/homepage/editorialboardprofiles.html. We are pleased with the enthusiastic participation of the young generation of researchers in the launch and growth of BioTM. The support came in various forms including guest editing of special issues, submission of manuscripts, and reviewing manuscripts. Our special thanks to Prof. Aaron Anselmo of University of North Carolina, Received: 2 August 2020 Accepted: 2 August 2020


Madame Chrysantheme is a novel of French writer Pierre Loti which describes his trip to Japan. In the eyes of Pierre Loti,Japan's natural and humanistic landscape is beautiful,but of petty formality. He expressed his disdain to the Japanese and his Japanese wife. From the perspective of imagologie,any foreign description is a kind of cultural imagination. Pierre Loti's description of Japan reflects the French people's pride and prejudice as the colonists from western developed countries.


The 6082 aluminium alloy is widely used for the automotive parts that work under the conditions of dynamic and cyclic stress, but the selection of proper production parameters is most challenging task to get excellent result. Physical simulation of HAZ helps in identifying suitable welding parameters like linear heat input, voltage, current etc. In this paper, the influence of weld heat cycle on heat affected zone (HAZ) is simulated for Tungsten Inert Gas Welding (TIG) using Gleeble 3500 thermomechanical simulator, automotive aluminium alloy (AA6082-T6) plate of thickness 1 mm. Investigation of HAZ softening were performed by means of hardness measurement on the simulated specimens. Different peak temperatures and linear heat input were selected, and physical simulation performed using Rykalin-2D model (thin plate). Experimental works included physical simulation and Vickers hardness tests.


Ultraviolet light (light at wavelengths between 100nm and 400 nm) has well-known disinfection properties. These properties stem from the ability of UV light to damage the proteins and genomic material of bacteria and viruses through the disruption of chemical bonds. Most UV disinfection systems use germicidal lamps of wavelengths 240nm-280nm, with the most common being 254nm. Unfortunately, exposure to 254nm UVC light also causes damage to skin and eyes in humans. However, recently published studies have demonstrated that UV light at 222nm has the same germicidal capabilities of 254nm light without damaging skin or eyes. The studies suggest that this may be due to the shorter UV 222nm wavelength (known as Far-UV, 200 to 235 nm) having reduced penetration depths in live tissue when compared with 254 nm light. While the effects on live tissue are diminished, Far-UV (222 nm light being the most prevalent) has increased efficacy for killing bacteria and viruses. Like standard UVC, Far-UV light breaks pathogen (bacteria and virus) DNA bonds, which is the primary source of microbial deactivation. Combined with the small size of bacteria and viruses, when compared to mammalian cells, the short penetration depth of Far-UV successfully deactivates these pathogens. The current literature also points to more deactivation of bacteria at lower doses of 222nm light than that required for 254nm light. This paper provides an overview of Far-UV 222 nm technology and its disinfection capability. Far-UV 222 nm is safer and more effective than the existing 250 to 280 nm UVC systems, with advantages that include reduced UV damage to skin and eyes, faster on/off times, more rapid disinfection, and the elimination of mercury from the lamp.


The system of counselors is an essential system in the education system of socialism with Chinese characteristics,which is established according to the need of our Party to strengthen her leadership over colleges and universities and to train eligible builders and successors of socialism.This system regulates and secures the construction of counselors group and is the sum of rules,norms,procedures and principles which embody the common will and interest of the counselors and students.Through analsying systematic characteristics of being habitual,normative,stable,historical and universal,this paper argues that the system of counselors in colleges and universities has the essential characteristics of system as well as distinct politicalness,and this is a formal system restrained by informal systems.The functional play of the system of counselors experienced a transformation from serving political needs to serving the students' allround development,which helps to guarantee the goal to cultivate socialist university talents,to enhance the education of college students to have socialist ideology and to maintain campus stability.


Wounds are inescapable events of life. Non-healing and chronic wounds pose significant health care problems in today's medical practice. 1 The wide spread of other chronic wounds, example: Diabetic wounds, war related missile wounds and venous stasis ulcer, further underscores the need for efficacious wound healing intervention. 2 Wound is a breech in continuity of tissue. Wound healing has a complex mechanism which holds numerous steps involving coagulation, inflammation, granulation tissue formation, matrix formation, connective tissue remodelling, collagenisation and wound strength acquisition. 3 Wounds have varying effects on the quality of life of those affected, their families and care givers. Appropriate treatment and wound care accelerates the healing process and prevents infection and chronicity of wound. Different methods and approaches have been used to achieve shorter wound healing times. 1 The quest for better wound healing agents is perhaps one of the oldest challenges for medical practice. 4 Currently, much attention and faith are being placed on development of expensive topical molecular factors for enhancement of wound healing. One such agent that has been tried in wound healing is Phenytoin. A common dose related side effect with Phenytoin when taken orally in treatment of epilepsy is gingival hyperplasia which led Shapiro to carry out first clinical study to evaluate the effect of Phenytoin on gingival wounds. 4 Phenytoin may promote wound healing through multiple mechanisms, including stimulation of fibroblast proliferation, facilitation of collagen deposition, glucocorticoid antagonism and antibacterial activity. This apparent stimulatory effect of Phenytoin on connective tissue suggested an exciting ABSTRACT


Objective To compare the difference on inducing cytokine-induced killer(CIK) cells between two kinds of anti-CD3 isotypes(UCHT1 and OKT3) in vitro.Methods Peripheral blood mononuclear cells were isolated from seven healthy normal individuals,and then different anti-CD3 isotypes were used to induce CIK cells respectively under the condition of PAA culture medium.The proliferations were counted for the CIK cells in the two different anti-CD3mAb isotypes on the days 3,10,12,14 and 21 of culture,respectively.The CIK cells at day 14 of culture were analyzed on the phenotype of CD3,CD8 and CD56 by a flow cytometry and on the killing abilities to K562 by the LDH release experiment.Results The CIK cells proliferations in OKT3 increased faster than those in UCHT1(P0.05),and the mean frequency of the CD+3CD+8 cell in the OKT3 group were significantly higher than the UCHT1 group(P0.05);The frequency of CD+56 cells in UCHT1 group was higher than those in OKT3(P0.05) and the frequency of CD+3CD+56 cells in OKT3 was lower than that in the UCHT1 group,but there was no statistically significant difference.For the killing abilities to K562 for the CIK cells,the higher tendency in the UCHT1 than the OKT3 group was showed(when ratio of effect cells to target cells is 20∶1,P=0.078).Conclusions Under the condition of ensuring the numbers of expanding CIK cells,UCHT1 is more applicable for CIK cells induction than OKT3.


The principal target of this work is to introduce and examine a novel kind of complex synchronization. This sort may be called complex anti-synchronization. There are surprising properties of complex anti-synchronization that do not exist in the writing, for example, (1) this sort of synchronization can dissect just for complex nonlinear frameworks. (2) The complex anti-synchronization contains or connects two sorts of synchronizations (anti-synchronization and complete synchronization). Anti-synchronization happens between the real part of main framework and the imaginary part of the slave framework, although complete synchronization accomplishes between the real part of slave framework and the imaginary part of the main framework. (3) In complex anti-synchronization, the attractors of the essential and slave structures are moving symmetrical to each other with a similar structure. (4) The state variable of the standard framework synchronizes with an other state variable of the slave structure. An explanation of complex anti-synchronization is presented for two indistinguishable chaotic complex nonlinear frameworks. In view of the Lyapunov function, a plan is intended to accomplish complex anti-synchronization of disordered or chaotic attractors of these frameworks. The effectiveness of the obtained results is outlined by a reenactment illustration. Numerical outcomes are plotted to show state variable, modulus errors, phase errors and the development of the attractors of these chaotic frameworks after synchronization to demonstrate that complex anti-synchronization is accomplished.


This article discusses a narrative inquiry as a methodology for understanding and examining teachers' interpretations of their environment‐related teaching experiences. Focusing on the value of teacher stories for interrogating the discursive practices of schools as institutional contexts, four main rhetorical themes are identified to illustrate how teachers' engagements in practice and thinking with environmental education display ongoing identity work. Five Korean secondary science teachers' stories illustrate the dynamic processes and interplay between multiple discourses, such as the 'proper', 'good', 'science' teacher, and the cultural norms, resources and subject positions available to them, as they take up and explain their own and others' meanings and subject positions in science education and environmental education. The paper discusses the value of narrative inquiry to conceptualising teacher agency in ways that offer alternatives to conventional research perspectives in this field, and in taking account of the possible meanings of environmental education, the possibility of creating cracks and ruptures in the 'sense‐making' discourses and 'sense that is made' of experiences of environmental education and school education more widely.


Then one Sunday afternoon in July you read a story about a woman who was raped by a man she thought was her friend, a man she thought was kind, a man she thought she might like to love, and you have heard the word rape before, and you remember how when you were little you thought it meant to have sex with someone, and you wonder where you got that idea, what your parents told you when you said that, where anyone got that idea, where did he get that idea, that you were something different than a person, that a woman is different than a person, a different kind of person, that a person is a door you can break into, that a person is meant for you to enter it [even though I do feel like a sort of cave, I am so hollowed out with sorrow], and you sit in your t-shirt and underwear and read this story three times and think about violence, his voice that you haven't figured out how to describe but every time you think about it you see him with his black hair screaming across the sky of your brain, you see him with his black hair, you see him and you wonder why the sky doesn't have more holes in it, how that blue stays so blue, the clouds passing through like the sweet sheep that they are, passive because they have to be, like the girl in the story had to be, how her body and brain went dead just to get it over with, so he wouldn't hit her, so he wouldn't hit you, and no he never hit you, he made sure to point this out to you over and over again and you said yes yes you are right I am so sorry.

Recently, many works for stereo matching with convolutional neural networks have gained satisfactory performance. However, it is still an urgent challenge to deal with ill-posed regions and improve details in disparity maps. To address these problems, we propose a multi-scale context attention network with three main modules: atrous spatial pyramid pooling attention, richer convolutional features, and attention mechanism. First, we propose an atrous spatial pyramid pooling attention module to capture context information by the aggregating context in different scales, meanwhile take advantage of the attention mechanism to selectively emphasize informative features and suppress fewer ones. Then, the richer convolutional module is proposed to bring useful detail information for the network. Additionally, attention mechanism is used to pick out informative features for disparity refinement sub-network. Furthermore, we design a point-specific loss function strategy to perform online hard point mining, which helps the network to improve the accuracy of disparity maps. The experiments on the FlyingThings3D and KITTI 2015 benchmark demonstrate that the proposed method can achieve state-of-the-art performance.


Objective To evaluate the effect of Chaihulonggumuli Decoction intervening depression. Methods We searched CNKI,VIP,WanFang( 1990 to 2012) for randomized control trials about Chaihulonggumuli Decoction intervening depression. Results Screening trials according to the inclusion and exclusion criteria and assessment the quality of included trials,the extraction of effective data,10 randomized clinical trials and their efficiency were evaluated; statistical analysis was conducted by using RevMan 4. 2 software. Meta analysis showed that the efficiency of Chaihulonggumuli Decoction on depression was better than the control group[RR = 1. 10,95% CI( 1. 04 1. 17),P 0. 05]; four trials which for depression affer stroke,RR = 1. 12,95% CI( 1. 04,1. 22). Conclusion The Chaihulonggumuli Decoction intervening depression was effective.


Following a brief review of Fick's laws and the theory of diffusion in a homogeneous medium, we consider the application of the Fickian model to diffusion in nanoporous materials. If the pore system is statistically uniform the simple Fickian model is directly applicable. Inhomogeneities such as surface or internal barriers require some adjustments to the model but Fick's equations still provide a valid approach. Hierarchical pore systems present a more serious challenge. When there is rapid exchange between the different regions such systems conform to the simple Fickian model, with a diffusivity corresponding to the mean of the diffusivities in the different regions. In contrast, when the condition of rapid exchange is not fulfilled the simple Fickian model is not applicable and the situation becomes more complicated. Simple hierarchical pore structures such as the micropore/macropore system typically found in commercial adsorbents and catalysts can still be described by a dual resistance Fickian model but for more complex hierarchical pore structures Monte Carlo or MD simulations offer the only realistic approach. The measurement of self-diffusion by PFG NMR and by microimaging (notably by interference microscopy) is also reviewed and selected examples are presented to show the detailed information that can be extracted from such measurements, especially when accompanied by molecular simulations. Examples highlighting the relevance of a detailed knowledge of the various steps of mass transfer for a transport-optimized technological application of nanoporous materials, notably for molecular separations and mass conversions, are provided.


SPECT Tc/sup 99m/ sestamibi imaging (SESTA) is used to assess myocardial perfusion. Few reports document SESTA left ventricle muscle mass (LVMM). This study compared the results of LVMM by electron beam CT, (EBCT) to that by SESTA SPECT. Thirty patients from a myocardial infarct study had ungated SESTA images acquired on Elscint SPECT gamma cameras. The reconstructed short axis images were exported in Interfile format to a workstation running Analyze AVW/sup TM/. SESTA LVMM analysis was performed using volume rendering and image editing in this program. Analysis is semiautomatic with some operator intervention and takes between 2 to 3 min. The mean LVMM EBCT was 167/spl plusmn/ 33 grams and LVMM SESTA 158/spl plusmn/34 grams (p=NS; correlation coefficient=0.72, coefficient of variation between methods=15.5%). SPECT LV mass determination may make an important adjunct to the other parameters assessed by sestamibi SPECT imaging.


Recent years have witnessed China's fundamental adjustment of its subsidizing policies on grain supplies to ensure two goals, namely, security of grain supplies and income rise of farmers, due to its emphasis on the "Three Rural Issues" concerning agriculture, farmers and the countryside, and the global crisis of grain shortage. However, there have long existed contradictions between the two goals as can be seen from the definition of security of grain supplies and features of the grain production industry. Taking the opportunity cost and farmers' interests of farming into account, it's essential to clarify their relationship and put farmers' income rise on the top agenda so as to make both ends meet. After a Game-Theory-based analysis, it's revealed that the subsidizing policy on grain supplies, namely direct grain-growing grants to farmers enacted by the Chinese Government has played a major role in reconciling both goals.


Query processing over uncertain data has gained much attention recently. Due to the high computational complexity of query evaluation on uncertain data, the data owner can outsource her data to a server that provides query evaluation as a service. However, a dishonest server may return cheap (and incorrect) query answers, hoping that the client who has weak computational power cannot catch the incorrect results. To address the integrity issue, in this paper, we design AuthPDB, a framework that supports efficient authentication of query evaluation for both all-answer and top-k queries on outsourced probabilistic databases. Our empirical results on real-world datasets demonstrate the effectiveness and efficiency of AuthPDB.


Abstract In the last 15 years, the Netherlands has witnessed the enormous growth of independent local parties and of their electoral support. In order to assess the success of independent locals in the Netherlands, this paper explores how independent local parties distinguish themselves ideologically, organisationally, and operationally. It presents the results of two online surveys of 1,800 independent and other local parties in the Netherlands. Compared to local party branches, independent local parties are more successful in performing the organisational, programmatic and nomination function of political parties. They are spearheading the change to a modern cadre party with politicians and a small number of active volunteers taking care of the party's rootedness in society. Furthermore, they enrich local politics with new political dividing lines, smoothing the entry of new demands, themes, and issues onto the political agenda. Finally, they are proving to be more resourceful in recruiting citizens to stand as candidates for municipal councillorship.


To investigate elastic waves' propagation laws in a heterogeneous fluid-solid 2-phase medium,this paper derived the wave propagation equations in a double-porosity model.The mathematical and physical basis and the practical significance of this theory are discussed in four aspects:model design,theoretical derivation,velocity dispersion and attenuation analysis and rock experiment verification.The velocity dispersion and attenuation analysis shows double-porosity wave theory is in good agreement with former theoretical results in all wave's characteristics.Comparisons with former theories in rock experiment verifications show that the double-porosity wave theory can provide much better prediction for the moderate-low frequency wave velocity dispersion in actual rocks.


Conventional immunosuppression consists of steroids, a calcineurin inhibitor (either cyclosporin or tacrolimus), and a lymphocyte proliferation inhibitor (azathioprine or mycophenolate mofetil). Induction therapy with a polyclonal antibody (ATG) or a monoclonal antibody (OKT3, Basiliximab or Daclizumab) is also an option. All immunosuppressive agents have side-effects, and alternatives to conventional immunosuppression, such as steroid-free or calcineurin-free protocols, have been described.


JUNO is an experiment aimed at detecting neutrino mass hierarchy. The innermost part of the JUNO detector is formed by 20,000 tons of liquid scintillator which should have very low level of radioactive materials, such as 238U, 232Th, and 40K. Since the radioactive level of raw LAB(the solvent of LS)cannot reach so stringent requirements of JUNO, the purification for LAB plays an extremely important role in LS production. This article studies the efficiency of several different purification methods for LS, like distillation, water extraction and Al2O3 purification.


The continuous scaling of feature dimensions and the introduction of new dielectric materials is pushing the interconnects closer to their reliability limits. Degradation mechanisms are becoming more pronounced, making the interconnect lifetime a challenge at the level of process qualification. Moreover, these mechanisms exhibit new properties, like gradual degradation of electrical parameters instead of abrupt breakdowns phenomena. As a result, it becomes more likely that systems will fail because one of their transistors or wires becomes gradually too slow. These soft failures are not captured by existing tools. The methodology introduced in this paper estimates the impact of two dominant interconnect degradation mechanisms (EM & TDDB) on the total system performance. This constitutes a first step toward system level driven reliability aware design.

Surrounded by the western"theoretical hegemony",curriculum research in China has been struggling in the contradictions of criticizing and inheriting,reference and innovation,diversification and unity.In order to resolve this problem,the key is to seek the breakthrough for the generation of native Chinese curriculum theories and the curriculum research methodology derived from the Chinese curriculum practice and aimed at the Chinese curriculum practice.In the context "cultural hegemony",it is the ideal pursuit of curriculum researchers to go towards the cultural consciousness.


The former Pb-Zn-mine "Grund" was the most important ore mine in the Upper Harz region. To drainage the mine, the adit "Ernst-August-Stollen" was built from 1851-1864. It is the youngest, largest, and deepest drainage adit of the Harz Mountains. In addition to the Grund mining districts, the adit with a length of 40 km also drains the mining districts Silbernaal, Wildemann, Zellerfeld, Clausthal, Bockswiese and Lautenthal. Although mining ended, in the other localities about 100 years ago


We present a novel optical flow estimation framework that reinterprets most popular algorithms (e.g., the Horn–Schunck model, PDE-based models, TV-based models, and nonlocal-based models) from an iterative filtering perspective. Different regularizers in the related optical flow estimation algorithms can be achieved by adopting different filtering operations. The key merit of the proposed framework is that a variety of filtering models and corresponding optimization strategies, which are used in image processing, can be directly utilized in the regularization term, leading to a convenient way of designing appropriate optical flow estimation algorithms. Under the proposed filtering framework, we demonstrate easily designing optical flow estimation algorithms with respect to translation consistency, rotation consistency, and divergence consistency constraints by adopting different spatial filters, respectively. We also derive a novel optical flow estimation algorithm with 3D filtering-based model for the regularization term, which makes use of nonlocal self-similarity and sparse characteristic of optical flow field. Benefited from the advantages of patch-based nonlocal sparse regularizer, the derived algorithm can remove outliers while preserving sharp flow edges and important motion details. At present, the proposed algorithm achieves a high ranking on the challenging MPI-Sintel dataset and shows good performance on the Kitti flow 2015 and Middlebury datasets.


English idiom is the conventionalized peculiar form of language which derived from the long-term accumulation of the English People and which entails lots of metaphor. This paper takes the examples of idioms denoting "happiness" and "sadness" and gives an analysis of metaphor in idioms. The analysis shows that metaphor plays an important role in the generation and abstraction of the meaning of idioms, the producing and understanding of metaphor originate from the cognitive process of people towards the social practice, which reflect the relationship of language and humans' thought and cognition.


The two important requirements in Wireless Senor Networks (WSNs) are end-to-end reliability and maximization of the network lifetime. Sensor nodes are energy constrained in nature. Therefore, energy efficient communication techniques and reliable delivery of the sensed data to the base-station (BS) are necessary. Maximum energy is consumed during transmission in comparison to data sensing. Redundant data increases the energy consumption during data transmission. In this paper, we propose an Energy Efficient Hierarchical Reliable Transport Protocol (EEHRTP) for reliable data transmission within the WSN. The objective of this study is to maximize the network lifetime by controlling the redundant data transmission with the co-ordination of the base-station. Performance evaluation via simulation experiments shows that the proposed protocol performs better than the existing protocols in terms of reliabilty and energy efficiency. Keywords: Energy efficient, transmission control protocol, reliability, wireless sensor network;


Abstract This preliminary publication will give information on the phase transitions which we confirmed by microscopic and calorimetric (Perkin Elmer DSC 2) measurements in some homologous series.


Let $h_{S}(f)$ denote the topological sequence entropy of $f$ respect to the sequence $S$ . We will prove the following. (1) $hs(f\mathrm{o}g)=hs(f\mathrm{o}f)$ for any sequence $S$ and any graph maps $f,g$ . (2) For each $n$-dimensional compact topological manifold $M$ with $n>1$ , there exist two continuous maps $\tilde{F},\tilde{G}$ : $Marrow M$ such that $0=hs_{2}(\tilde{F}\circ$ (7) $<\log 2\leq h_{S_{2}}(\tilde{G}\circ\tilde{F})$ and $0=h_{S_{2}}(\tilde{F}|_{\Omega(\overline{F})})<\log 2\leq h_{S_{2}}(\tilde{F})$, where $s_{2}=(2:)_{\dot{\iota}=1}^{\infty}$ and $\Omega(\tilde{F})$ is the set of nonwandering points of $\tilde{F}$ . (3) Agraph map $f$ is chaotic in the sense of Li-Yorke if and only if the shift map $\sigma_{f}$ : $\lim_{arrow}(X, f)arrow\lim_{arrow}(X, f)$ is chaotic in the sense of Li-Yorke. (4) For any $n$-dimensional compact topological manifold $M$ with $n\geq 2$ , we construct achaotic map $f_{M}$ in the sense of Li-Yorke from $M$ to itself such that the shift map $\sigma_{f_{M}}$ is not chaotic in the sense of Li-Yorke. (1) and (2) are the affirmative answers of questions in [BCL, Remark 4.7].


The advent of wireless technology, such as cellphones, PDAs, tablet PCs, and sub-notebooks, allows transferring portions of traditional, desktop-based GIS technology to mobile environments. This paper introduces Geo-Mobile Query-by-Sketch, a sketch-based spatial querying system for mobile GIS environments that combines techniques for spatial querying with mobile technologies. The system implements an adaptive client-server architecture, which copes with restrictions of mobile environments, such as fluctuating bandwidth and frequent disconnections. The core concept analysed is the mobile sketch, a multi-representation data structure of a sketched scene, which enables an adaptation strategy that is tailored to the available transmission rates. We analyse the transmission cost of Geo-Mobile Query-by-Sketch and develop a protocol that optimises the adaptation level in order to guarantee quality of service.


We prove that there exists a constant $\varepsilon>0$ with the following property: if $K \subset \mathbb{R}^{2}$ is a compact set which contains no pair of the form $\{x, x + (z, z^{2})\}$ for $z \neq 0$, then $\mathrm{dim}_\mathrm{H} K \leq 2 - \varepsilon$.


We study the effect of interparticle interaction $U$ on the spectrum of the Harper model and show that it leads to a pure-point component arising from the multifractal spectrum of the noninteracting problem. Our numerical studies allow us to understand the global structure of the spectrum. An analytical approach developed permits us to understand the origin of localized states in the limit of strong interaction $U$ and fine spectral structure for small $U$.


User-centric business intelligence aims at empowering analysts who interact with complex tools, by allowing them to perform accurate data manipulations and analysis without necessarily requiring IT expertise and knowledge of underlying data specifications. Recommender systems contribute to easing their tasks but most of them operate inside walled gardens and cannot assist properly the user throughout his BI workflow. In this paper we introduce a lightweight vocabulary intended to capture fragments of analytical workflows as multidimensional data transformations, within a Semantic Web framework. We utilize this model for calculating content-based recommendations.


The distant long-period comet C/2017 K2 (PANSTARRS) has been outside the planetary region of the solar system for ∼3 Myr, negating the possibility that heat retained from the previous perihelion could be responsible for its activity. This inbound comet is also too cold for water ice to sublimate and too cold for amorphous water ice, if present, to crystallize. C/2017 K2 thus presents an ideal target in which to investigate the mechanisms responsible for activity in distant comets. We have used the Hubble Space Telescope to study the comet in the pre-perihelion heliocentric distance range 13.8 ≤ rH ≤ 15.9 au. In this range, the coma maintains a logarithmic surface brightness gradient m = −1.010 ± 0.004, consistent with mass loss proceeding in steady state. The absence of a radiation pressure swept tail indicates that the effective particle size is large (radius ≳0.1 mm) and the mass-loss rate is ∼200 kg s−1, remarkable for a comet still beyond the orbit of Saturn. Extrapolation of the photometry indicates that activity began in 2012.1 ± 0.5, at rH = 25.9 ± 0.9 au, where the isothermal blackbody temperature is only TBB = 55 K. This large distance and low temperature suggest that cometary activity is driven by the sublimation of a super-volatile ice (e.g., CO), presumably preserved by K2's long-term residence in the Oort cloud. The mass-loss rate can be sustained by CO sublimation from an area ≲2 km2, if located near the hot subsolar point on the nucleus. However, while the drag force from sublimated CO is sufficient to lift millimeter-sized particles against the gravity of the cometary nucleus, it is 102–103 times too small to eject these particles against interparticle cohesion. Our observations thus require either a new understanding of the physics of interparticle cohesion or the introduction of another mechanism to drive distant cometary mass loss. We suggest thermal fracture and electrostatic supercharging in this context.


Abstract:How should survival strategies of resource-dependent Chinese civil society organisations (CSOs) be re-conceptualised in order to narrow the gap between civil society research and emerging CSO practices? Specifically, to what extent have CSOs managed to leverage scarce resources to secure organisational survival? Drawing on Bourdieu's concepts, the authors engage in theoretical innovation by explaining how CSOs have engaged in a resource mobilisation cycle, whereby practitioners draw on their cultural, economic, symbolic and social capital. Their findings highlight the view that Chinese CSOs have varying levels of access to support their work from four resource pools, namely global civil society, the Party–state, the private sector, and local constituents and local communities.


A rare case of neonatal shigellosis caused by Shigella boydii in a preterm neonate, severe enough to necessitate intensive care support, is presented. The roles of breast-feeding, hand-washing and surveillance for enteric infections in the prevention of shigellosis in low risk settings such as a special care baby unit are highlighted.


Various process parameters exert different effects in stamping process. In order to study the relationships among the process parameters of box stamping process, including the blank holder force, friction coefficient, depth of drawbead, offset and length of drawbead, the decision tree algorithm C4.5 was performed to generate the decision tree using the result data of the box stamping simulation. The design and improvement methods of the decision tree were presented. Potential and valuable rules were generated by traversing the decision tree, which plays an instructive role on the practical design. The rules show that the correct combination of blank holder force and setting of drawbead are the dominant contribution for controlling the cracking and wrinkling in box stamping process. In order to validate the rules, the stamping process for box was also performed. The experiment results show good agreement with the generated rules.


This study aims to find out the internalization of multiculturalism values through Arabic teaching at Islamic senior high schools in Palu city Indonesia. The integration of multiculturalism values in learning materials is considered very important to create students' moderate attitudes toward ethnicity and cultural differences in schools' daily life. This study was carried out using a case study qualitative approach. Data were gathered through field observation, and in-depth interviews with the school principal, teachers, and students. Our study found that multiculturalism values were integrated through the Arabic curriculum, lesson plans, learning material, and students' activities. The multiculturalism values were reflected in the students' daily life in the forms of ethnicity diversity tolerance, respect attitudes, and moderate behavior. Our study contributes to the body of knowledge in multiculturalism studies and practices by providing a new direction to multicultural integration strategies at the school level. Future studies should focus on how the broader context of studies such as by involving more than one case.


Just as rising concern about its environmental, economic, social, health and quality of life downsides generates loud calls for a departure from the dispersed car-oriented urban model, conditions for such a transition have become more uncertain. The intended urban shift is hampered by dissonance between the generation of metropolitan-scale planning visions and the anti-interventionist characteristics of the current neo-liberal age. The paper identifies impeding effects of neo-liberalism—notably, public funding hardship and political dynamics—on attempts at carrying out transformative metropolitan planning. The difficulty in preventing major failures in the operation of cities under neo-liberalism is reflective of its inability, at a broader societal scale, to regulate the economy and thus avert economic and social crises. The paper draws its empirical substance from the gap in Toronto, Canada, between metropolitan planning visions and the urban development reality.


This thesis explores teacher educators' cognitions in the context of a new five-year-long undergraduate English Language teaching programme at a private university in Chile. This programme is called Integrated Curriculum since its main principle is to teach all its curricular strands, i.e. integrated English language (IEL), methodology, education and school internships in an integrated fashion, enabling the content and teaching/learning processes of each strand to feed into and draw from the others. The Integrated Curriculum is inspired by the principles of critical pedagogy and social justice.
This case study followed a qualitative research design, within a critical theory paradigm. The data generation consisted of semi-structured interviews and classroom observations of four teacher educators teaching at the IEL strand. The IEL strand concentrates 60% of the teaching hours of the integrated curriculum, and most teacher educators work on this area. Interviews also included the programme leaders, and twenty-six student teachers.
The findings showed that teacher educators are very committed to the programme. However, the complex organisational system hinders their opportunities for reflection, on-going improvement, and addressing student-teachers' teaching and learning needs. The programme leaders are aware of the difficulties that teacher educators face while implementing it. Student teachers seem to have a limited perspective of the integrated curriculum and appear to struggle to understand the innovative language teaching approach promoted by the IEL.
This study demonstrates that complex curriculum change takes time and resources. In this case, despite being well intended, the speed of the change, the lack of forward planning, and existing models to refer to, have limited the IC achievements. Findings suggest that changes in teacher education require a close connection with the school contexts to gauge the feasibility of the innovation in reality, to inform teacher educators and student teachers to teach and learn in mainly unchanged educational contexts.


An imaging system TOMBO is based on a compound-eye camera whose image sensor is divided by small lenses. It has compact hardware and acquires multiple kinds of images at a time. In this research, we developed a mobile multi-spectral compound-eye TOMBO system capable of capturing subjects in a field environment. On the system, an embedded computer controls the TOMBO system. The developed system was mounted on an unmanned aerial vehicle and captured aerial images. We evaluated the images by a normalized difference vegetation index (NDVI) used in remote sensing and confirmed the usefulness of the proposed system.


The speedy dissemination of digital consumer electronics devices within home and personal area causes increments of multimedia communication and advent of entertainment networking. This feature of communication requires variable data-rate and reliable transmission. In order to meet the various demands, in this paper, the multiband orthogonal frequency division multiplexing (MBOFDM) ultra-wideband (UWB) system by exploiting a time domain spreading factor and multiple-access scheme is proposed for variable data-rate transmission from 20kbps to 960Mbps in wireless communication. This article presents the basic structure and main functions of the variable data-rate (VR)-UWB system. With an emphasis on a proposed idea, we address the multiple-access in MB-OFDM system and apply adaptive bit allocation schemes to OFDMA system. It is shown in this article that scale-free UWB can accept multiple users and provide variable data-rate as well as support reliable transmission, while most conventional studies focus on the fixed rate transmission. The proposed system will be promising solution in ubiquitous environment to support multimedia traffic with various rates.


The effect of the iodine interphase transport originated from physical processes, such as pressure decrease, vigorous stirring, and/or an inert gas bubbling, on the dynamics of the oscillating Bray−Liebhafsky reaction is studied. Some new experiments were made at 60 °C that confirmed the possibility of suppressing oscillations by means of the iodine vapor removal from the reaction solution. It has been proved that the iodine vaporization is governed by the first-order kinetics with respect to the concentration of aqueous iodine, and a critical rate constant for iodine escape causing inhibition of the oscillatory mode was determined. The experiments were confronted with the models proposed by Kolar-Anic and Schmitz with co-workers. Both the models studied reflect the observed phenomenon. A simulation based on the latest model shows very good semiquantitative agreement with experiment, needing only a minor modification of the rate constants suggested by Kolar-Anic et al.


, Alessandro Manzoni remains an enigmatic figure, imperfect1y understood by American scholars, and unknown to the general public. This relative neglect has done much to obscure the intrinsic merits of his work. Students of I talian literature' have advanced various hypotheses to account for the ignominious position of Manzoni in American letters. Curiously enough, Manzoni's name and works enjoyed well-merited popularity in America during the 1830's. The criticaI commentaries upon . his work which date from this period demonstrate a deep appreciation and understanding of his art, and offer revealing insights into the extent of his currency. This appreciation gains particular interest when one considers the oblivion into which Manzoni has fallen in America in contrast to the popularity which he continues to enjoy in Italy. The 1830's represent a period during which Italy and Italian writers enjoyed greater diffusion than the decade which preceded or the one which followed. Most of the works of Alessandro Manzoni, Silvio Pellico, and a score of other ltalian writers were translated into English. Considerable credit for this circulation must go to Elizabeth F. Ellet 2 who prodigiously discussed ltalian writers with considerable criticaI insight and erudition. I t .is at this time that she produced a series of articles dedicated to: "Modern Italian Novels"; "Specimens of the I talian T ragedians "; and " I talian Lyrical Poetry." There has been hitherto no adequate account of Manzoni's reception in the United States immediately following the first publication of the Promessi sposi in 1827. In the present study I wish to consider the two translations made in the United States in 1834 of this work; the validity of the commentaries of that period when compared to contemporary criticism; and the interpretative procedures which accounted for Manzoni' s success. The two translations of the Promessi sposi 4 by two different American publishing houses are indicative of the

In 1988, the Boston (Mass.) Water and Sewer Commission began investigating the possibility of downsizing meters as a way of reducing unaccounted-for water. The authors of this article demonstrate that downsizing was successful for a variety of the commission's accounts. As of May 17, 1991, the commission had recovered more than 429,905 gpd of water by downsizing more than 400 meters of size 1.5 in. and larger. In addition to reducing unaccounted-for water, the downsizing effort could generate more than $2 million annually


We report a case of bilateral facial nerve palsy caused by adult T cell leukemia/lymphoma (ATLL). A 51-year-old female consulted our department because of right facial palsy. Steroid therapy was performed, and her right facial palsy was recovered. However, sixteen days after the onset of right facial palsy, left facial palsy developed. She was diagnosed as having ATLL based on blood examination. Chemotherapy was performed but the patient died two months later.


Receptors believed responsible for the diuresis of negative pressure breathing have been located by observing the effect on urine flow of a stepwise engorgement of the intrathoracic vascular bed. Distension of the pulmonary arterial tree (injection of plastic beads) and of the entire pulmonary circulation (snares on the pulmonary veins) were without effect. A diuresis was however elicited by expansion of a balloon in the left atrium. It is concluded that stretch receptors in the left atrium and terminal pulmonary veins are instrumental in a mechanism linking changes in the actively circulating blood volume with homeostatic responses of the kidney.


Thyroid gland is the only endocrine gland which is amenable to direct physical examination owing to its large size and superficial location. The cause and type of thyroid swellings vary across geographical areas, lifestyles, and socioeconomic status of people. The incidence of palpable thyroid swellings is 4-7% out of which only 1% are malignant. Out of all thyroidectomy cases, histologically confirmed thyroid malignancy constitutes only 20%. Incidence of thyroid malignancy increases with age, history of radiation exposure, and diet containing goitrogenic material. In northeast India, frequent floods and changes in the course of rivers depletes the soil of iodine which is the cause for a high prevalence of goiter and thyroid swelling in the area.

This symposium article discusses recent state constitutional amendments limiting marriage, suggesting that many of the rationales offered in support of such amendments involve faculty factual assertions or conclusions which do not follow from the premises offered. The article concludes that the state marriage amendments do not strengthen marriage but instead make it a political tool, thereby sullying it in the name of protecting it.


A study is performed on the interactivity of virtual humans with the virtual terrain during locomotion by walking. Collision detection is implemented to locate the walker correctly above the ground in the virtual world. Approach of motion blending is employed to generate new motion data to animate in real-time the virtual humans in a believable reaction to the change of environment. The blending weights of the walking motion are determined by the two gradients of the terrain along and across the locomotion direction. Geometric analysis on the terrain is also carried out for the virtual humans' perception to the terrain around.

Measurements of particles in liquid are important application for biosensor, process monitoring, and so on. In this paper, we present experimental consideration of particle measurements using a shear horizontal surface acoustic wave (SH-SAW) sensor. The SH-SAW sensor was fabricated on a 36YX-LiTaO3 single crystal. The SH-SAW is influenced by mechanical and electrical perturbations of the adjacent medium on the propagating surface [1]. A three-channel SH-SAW sensor was proposed [2] for simultaneous detection of the perturbations (Fig. 1). The mechanical perturbation of the SH-SAW was obtained from the differential signals between ch. 1 and ch. 2, while the electrical perturbation was obtained from the differential signals between ch. 2 and ch. 3. In the measurement, distilled water was used as the reference liquid. We measured phase difference between two channels using a vector voltmeter.

The utilization of electric generation capacity is generally set by studies of load growth. In recent years, load growth in developed countries has not been at high levels, and the utilization of some renewable generation resources have exacerbated this issue. In this paper, a new market for large scale seawater desalination is proposed and discussed. The main elements of the discussion center on power system load factor improvement, the improvement of net present value, and also the coordination of desalination activity with system unit commitment. As a background, added water resources are noted as an important worldwide priority. The focus is on reverse osmosis as the desalination method.


Because of the rapid growth in agricultural yields plants and the temporal variation of satellite pass over the fields (e.g. 8-days repeat coverage between Landsat 7&8), and for the purpose of accuracy in estimating the amount of the expected crop yields that can be obtained by utilizing different satellite's images. The present research introduces a chronological calibration method for individual satellite image bands. Gaps bridging method based on the neighborhood is used to correct the failure of Scan Line Corrector (SLC) occurred in ETM+ images. The Landsat images are corrected by converting their density values to Top of Atmosphere (ToA) reflectance. Two methods have been suggested to remove the effects of phenology within the 8-days interval between Landsat 7 and 8 images; i.e. utilizing the linear regression equation and the crosscorrelation-factor. Image classification method based on scatterplot between the Visible Red (VR) and Near Infrared (NIR) bands is used to validate the application of these correction methods, by comparing the detected rates of Landcover components in images of the study area.
