A nonperturbative geometric formulation of the N=2 Neveu–Schwarz superstring theory which has been recently interpreted by H. Ooguri and C. Vafa [Mod. Phys. Lett. A5, 1389 (1990)] as a consistent quantum theory of self‐dual gravity in four dimensions, is constructed. It is shown that the natural complex structure over the loop superspace ΩMd‖d associated to the N=2 Neveu–Schwarz fermionic string, is invariant under symmetry group OSp(2‖2)⊆SuperdiffS1‖2. Moreover, it is proved that there is a unique Lorentz and OSp(2‖2) invariant complex structure on ΩMd‖d. This result implies that the superspace of all admissible complex structures over ΩMd‖d is isomorphic to the homogeneous Kahler supermanifold SuperdiffS1‖2/OSp(2‖2). The Ricci curvature of SuperdiffS1‖2/OSp(2‖2) is calculated. Applying the method of geometric quantization to the N=2 Neveu–Schwarz superstring theory along the lines suggested by M. J. Bowick and S. G. Rajeev [Nucl. Phys. B361, 469 (1991)], a representation is constructed of nonperturbativ...

Students who do not meet this criteria are eligible to apply, and can also be recommended by faculty, but should understand that departmental and overall GPA are a major part of the scholarship selection criteria for most scholarships.


The article examines the current trends and features of US and EU protectionism towards Russia, its possible consequences and ways of response. Protectionism has been increasing since 2020, which is manifested in the intensification of the use of existing instruments and the development of the new ones.The article analyzes possible consequences of the spike in countervailing investigations by the US against Russia. The author highlights possible application of similar restrictive measures by other partners as an additional risk. An unprecedented event is the US Department of Commerce review of Russia's status as a market economy country for purposes of antidumping duty investigations. Non-market economy status expands the capabilities of the US to "overcount" dumping and impose duties, thus impeding the activity of Russian companies on foreign markets. The US acknowledged for now that there does not exist a sufficient degree of evidence to justify a change in Russia's market economy designation, nevertheless, one cannot rule out such attempts in the future.In the EU context, the practice of energy adjustments, which results in overstated production costs, normal value and anti-dumping duties for Russian goods, is continued. A new protectionist step is the publication of the report "On significant distortions in the economy of the Russian Federation for the purposes of trade defence investigations", which lays an additional basis for the continuation and strengthening of restrictive measures. The article analyzes a new instrument of environmental protectionism, the EU's carbon border adjustment mechanism, a levy on imported products based on the embedded CO2 emissions. The measure will affect important positions of the Russian exports – cement, electricity, fertilizers, iron & steel and aluminum. The mechanism can be considered an attempt to make up for the EU's lack of natural competitive advantages in mineral raw materials and to impose its vision of economic policy goals on the rest of the world.In conclusion, the author highlights features of American and European protectionism towards Russia – active employment of the role of the state in the economy factor as well as environmental factor as pretexts for introducing or tightening restrictive measures.The main ways of Russia's response to new challenges can be the use of the WTO platform in cooperation with other countries, the search for new economic levers in relations with the partners (including application of trade defence measures), the detection of possible market distortions in the EU and the US for possible use in EAEU investigations.


Solid solutions of Sr1-xLaxPbO3 (x = 0, 0.05, 0.10, 0.15 and 0.20) were synthesized with the help of high pressure. Temperature (T) dependences of the resistivity r and differential thermoelectric power S were measured. All samples demonstrate an increase of r for low T and no signs of a bulk superconducting transition. The sign of S(T) is positive for x = 0.05 and 0.10, whereas S(T) changes sign from positive to negative for x = 0.15. Tunnel measurements were carried out using the break-junction technique. The sample SrPbO3 reveals a correlation dielectric gap Sigma = 1.5 ~ 2 eV. On the other hand, Sr(0.9)La(0.1)PbO3 shows a Josephson tunnel current and a superconducting gap of approximately 10 meV. This is the first such observation for the studied family of oxides. The results may help to resolve the existing controversy over superconductivity in the conglomerates Cu24Pb2Sr2Ag2Ox.


The purpose of this study is to determine the degree to which early childhood professionals from various occupations perceive early childhood language development to be impacted by Sign Language. Early childhood specialists, including teachers, and, speech-language pathologists were asked to participate in this study. Of those asked to participate 79 responses were collected. An electronic questionnaire that included demographic information as well as questions about the contribution of sign language to language development was constructed from the literature. A questionnaire was electronically distributed using Survey Monkey. Findings showed that these early childhood specialist agreed sign language can be beneficial to language development in children. Sign Language and Early Childhood Development 3 American Sign Language in Early Development American Sign Language (ASL) has been used as the main method of communication for deaf individuals since the early 19 century. Sign language has grown widely since then and now has many different dialects throughout the world. In the recent literature there is a considerable amount of information on the importance of this mode of communication in the Deaf community. The focus of this study is to better understand how widespread the appreciation of sign languages are to early development by teachers and other early childhood professionals. Review of Literature


Knowing remaining useful life (RUL) of bearing can better ensure the safe and effective production activities. The feature learning performance of traditional prognosis models is influenced by the noise characteristics of the original vibration signal with ease. In view of the limitation, a RUL prediction approach on the strength of the multi-scale convolutional neural network with Squeeze-and-Excitation mechanism (MsCNN_SE) is proposed. Continuous wavelet transform (CWT) is used to extract time-frequency characteristics from original signals, which are considered as the input of MsCNN_SE model for RUL prediction. The designed multi-scale network can extract richer local information and alleviate the phenomenon of gradient disappearance by increasing the network width. To reduce the interference of redundant features, the Squeeze-and-Excitation (SE) mechanism is introduced to enhance the correlation between features. Compared with the traditional convolutional neural network, the MsCNN_SE model can maintain global and local information at the same time. The validity of the proposed approach is verified by experimental data, and it shows a good prediction performance.

The purpose of this study was to ascertain whether premature luteolysis can be alleviated by substituting the ovulation inducing agent hCG for GnRH. Seventy-two hours after the end of artificial insemination (AI), pluriparous Awassi ewes were randomly assigned to one of three treatment groups of 13 ewes each. First group received 37.5 µg of the GnRH analog Lecirelin, the second 1000 I.U hCG and the third group served as a control (received 1 mL of physiological saline solution). Blood samples were collected at daily intervals after GnRH treatment and analyzed for plasma estradiol and progesterone concentrations. Ovarian follicles were monitored ultrasonically at the time of GnRH administration, 60 hours, and 84 hours later. Pregnancy was diagnosed ultrasonically at Day 35 after AI. Number and size of ovarian follicles did not differ (P>0.05) among treatment groups. Onset and duration of estrus were not affected by treatment (P>0.05). No significant differences (P>0.05) were recorded in estradiol and progesterone concentrations between the treatment groups during the inspection period. Premature luteolysis became evident in ewes with longer estrus durations by Day 6.25 after AI and amounted to 7.69%, 18.18% and 23.07% in GnRH, hCG and Control groups respectively. Pregnancy rates increased to 92.31% and 81.82% in GnRH and hCG groups, compared to 76.92% in the Control group. The results indicate that GnRH was more effective in reducing premature luteolysis than hCG. Substituting hCG for GnRH as an ovulation inducing agent was of no avail.


The thermoluminescence of X-ray coloured NaCl and NaCl:Cu crystals is studied in the temperature range 300 K-510 K. Five glow peaks centred at 343, 363, 391, 420 and 445 K are recorded for a warming rate of 40 K min-1 and analysis indicates first order kinetics with activation energies 1.05, 1.12, 1.21, 1.47 and 1.47 eV respectively. The 391 and 420 K peaks can be related to the presence of dissolved copper ions. The first (391 K) is ascribed to hole release from Cu2+ centres formed by irradiation while electron release from an F centre neighbouring a Cu2+ ion is believed to cause the 420 K peak. It is suggested that the other peaks originate from F centres generated during the initial growth stages.


Astaxanthin (AST), (family xanthophylls), is a food colorant used for animal, fish and nutritional supplements in humans. It has antioxidant activity. Brain and spinal cord injuries need neuroprotective treatment. The AST protects neuronal apoptosis and promotes regeneration. It quenches the free radicals to inhibit lipid peroxidation of neurons and promotes antioxidant enzyme production. Additionally the AST possesses anti-inflammatory property and prevents brain edema.


Abstract Objectives: To carry out a proof-of-concept study on the development of dual-drug amorphous nanoparticle complex (nanoplex in short) as a potential formulation platform for fixed-dose combination (FDC) of poorly-soluble drugs. Significance: FDC has been proven effective in improving patient compliance for treatment that requires complex multidrug regimen. Currently, there is growing interest to develop FDC of poorly-soluble drugs due to the increased number of drugs exhibiting poor solubility thus low bioavailability. Methods: The dual-drug nanoplex was prepared by electrostatically-driven co-complexation of drug molecules with oppositely charged dextran sulfate, using ciprofloxacin (CIP) and itraconazole (ITZ) as the model poorly-soluble drugs. Results: We first verified that the co-complexation products were dual-drug CIP-ITZ nanoplex, and not binary mixtures of the single-drug CIP and ITZ nanoplexes, by demonstrating their distinct thermal behaviors and dissolution characteristics. Depending on the preparation condition, the dual-drug nanoplex exhibited size and zeta potential of 160–410 nm and −35–50 mV, respectively. The individual drug payloads were readily manipulated by varying the CIP/ITZ mass ratio in the feed, resulting in CIP and ITZ payloads in the range of 60-30% and 15-45%, respectively. The CIP-ITZ nanoplex, however, exhibited diminished CIP supersaturation generation, thus lower CIP solubility enhancement, compared to the single-drug CIP nanoplex. The CIP-ITZ nanoplex, nonetheless, remained capable of generating high ITZ supersaturation level. Conclusion: Dual-drug nanoplex was successfully prepared with a high degree of control over its physical characteristics. Nevertheless, whether dual-drug nanoplex always exhibits diminished solubility enhancement compared to its single-drug counterparts needs to be investigated using different poorly-soluble drugs.


The butanone sensor based on metal oxide semiconductor (MOS) are anticipated with a high response and a low detection limit through a simple process. In order to solve the issue of insufficient sensing performance of a pure metal oxide, high selective ZnO sensor with ppb detection limit are successfully prepared by convenient hydrothermal method, moreover, the particle size of materials is adjusted by calcination temperature based on the Deby length for optimizing the sensor performance. All sensors are tested for response in the concentration range of 0.2 ppm to 100 ppm butanone. When the particle size is closer to 2 times the Debye length, the material exhibits a higher response to 100 ppm of butanone at the optimum operating temperature. In particular, the synthesized M-ZnO-400 sensor has a response 151 to 100 ppm butanone at 310 °C, with the detection limit of 200 ppb, the response time of 4.5 s, as well as the recovery time of 5 s. It is worth noting that response of the prepared sensor to butanone is at least 62 times higher than that of chlorobenzene, vinyl benzene, xylene, toluene, benzene, acetaldehyde and formaldehyde. In addition, the population analysis for the different bonds of the target gases are calculated by first principles simulation to further explain the high selectivity of butanone.

Works related to religious people constitute an important part of the Party's tasks. The successful completion of such works is not only a theoretical issue, but also a practical issue. In the new stage of building an overall well-to-do society, it is a major issue for all our theoretical and practical workers to think about. We should not only fully understand the historical position of religious people as well as the importance and necessity of works related to them, but also try our best to successfully complete such works.


Identification of influencing factors on runoff is a key to runoff forecasting,which could offer a scientific support for further study the evolution of runoff.This paper takes monthly runoff as an example and uses the data on monthly runoff and the average precipitation of the Shitouhe watershed from 1954 to 2007 to select the possible factors according to cause analysis,then uses the relevant probability,single correlation coefficient and Spearman coefficient to analyze correlativity,gets the main factors from the consolidated results of above analysis methods.The results show that runoff occurring in January and November is mainly affected by runoff of previous month,monthly runoff of March and December is mainly affected by the runoff occurring in advance of that two months.Runoff of February,April,July,August and October are affected by precipitation with previous monthly runoff.Runoff of May,June and September is mainly affected by the monthly precipitation.

Traditional methods of empirically implementing the popular Armington trade model are shown to result in theoretically and statistically inconsistent parameter estimates. A method for removing these inconsistencies within the framework of the Armington model is provided, along with a comparison of results of our new consistent procedure with those of the previous procedure.


Media discourse is a type of discourse that is seen as a broadcast platform in which the discourse is directed to a non-present reader, listener, or viewer (O'Keeffe, 2011, p. 441). The study of media discourse is important to understand and interpret the ideologies hidden within the adopted discourse. Topoi analysis is seen as argumentation-schemes within the field of critical discourse analysis that help connect the linguistic means to the macro-sociological and ideological levels implied within the selected discourse. The present study aims to investigate the use of topoi in Putin's speeches during the Russian-Ukrainian war of 2022. The study shows how Putin utilizes topoi in his speeches and their ideological impact. The adopted methodology is qualitative in nature depending on the model of Wodak et. al. (2009) argumentation-schemes (i.e., topoi) are seen as a bridge between different linguistic means and macro strategies as ideological in the presentation of identified social actors.


ABSTRACT Telephone counselling with adolescents is well known in many countries all over the world, due to its special characteristics, which seem to suit to adolescents. Some of these characteristics are the low cost, the easy access, the anonymity, as well as the possibility for the callers to have the control over the call regarding its duration as they can hang up the phone whenever they feel like it. Based on the experience gained from the operation of the telephone counselling helpline in Greece for children and adolescents, countertransference phenomena that appear during telephone counselling are presented in the present article. More specifically, the link between those countertransference phenomena and the special characteristics of telephone counselling, with the characteristics of the period of adolescence, with the existence of psychopathology in the callers and, moreover, with factors regarding the counsellors themselves is presented.


The skilled artisans who construct lead (tenor) steelpans generally attempt to tune the first three resonances of each note harmonically. When successful, the tuning leads to neighboring notes sharing the same frequency for the first two harmonics of each note on the outer ring of the steelpan. The sympathetic excitation of the neighboring notes is believed to contribute significantly to the unique timbre of the steelpan's characteristic sound. A series of custom steelpans with fewer notes was commissioned to understand better the nature of the coupling between the struck note and sympathetically vibrating notes. Electronic speckle pattern interferometry was used to compare the coupling between notes on standard tenor steelpan with the coupling between notes on the customized steelpan having fewer notes.


In the enthusiastic élan of the Renaissance, everything seemed possible. Belief in man's infinite capacity for understanding led to the ever-greater questioning of the Church and its practices. While in intellectual circles of the day, the ideas of Luther and Calvin began to circulate, Evangelicals argued for the restitution of the wellspring of religion, the Bible. One practitioner of devotio moderna was the sister of King François I of France, Marguerite de Navarre. By means of a configurational model developed by Eugene E. White, this article examines the theologically-assertive nature of the Queen of Navarre's collection of nouvelles, L'Heptaméron, and questions its efficacy on the subject of affecting religious reforms in sixteenth century France.


If an online discussion group is a privileged tool to create a CSCL environment, few studies to our knowledge investigated the combined effects of the uses of a knowledge structuring tool and an asynchronous communication tool in the development of skills. In this study, we describe a pedagogical script with an online discussion board and an etherpad to support the collaborative process. A shared edition space gives to learners the possibility to produce the synthesis of their solutions as they discussed before within the online discussion board. With a pretest/posttest design and a logs exploitation, our analysis shows that only the activity in the forum contributes to explain a progression in conceptualization. In analysis, we observe that the activity of Etherpad interacts positively with the activity in the discussion board and the prior knowledge of students. Concerning the analysis of the process, we observe that the learner's behavior is more homogeneous in the Etherpad than in the discussion board and the participation is more stable during the two tasks in the discussion board than in the etherpad.


Remote sensing images are often contaminated by varying degrees of stripes, which severely affects the visual quality and subsequent application of the data. Unlike with conventional methods, we achieve the destriping by separating the stripe component based on a full analysis of the various stripe properties. Under an optimization framework, an ℓ0-norm-based regularization is used to characterize the global sparse distribution of the stripes. In addition, difference-based constraints are adopted to describe the local smoothness and discontinuity in the along-stripe and across-stripe directions, respectively. The alternating direction method of multipliers is applied to solve and accelerate the model optimization. Experiments with both simulated and real data demonstrate the effectiveness of the proposed model, in terms of both qualitative and quantitative perspectives.


Pulse and pulse-chase experiments have identified the presence of partially glycosylated precursors of the a and ,B subunits of human chorionic gonadotropin (hCG) in cultured JAR choriocarcinoma cells. The a subunit precursor has an apparent molecular weight (by sodium dodecyl sulfate/polyacrylamide gel electrophoresis) of 18,000 (compared to 22,000 for fully processed a subunit); the , subunit precursor has an apparent molecular weight of 24,000 (fully processed, 34,000). Both of these precursors appear to have an intracellular half-life of at least 1 hr and to contain the mannose core but not the terminal carbohydrate sequences. Fully processed a and , subunits do not accumulate intracellularly, indicating that further processing of the precursors is followed by rapid secretion. Human chorionic gonadotropin (hCG; choriogonadotropin) is produced eutopically by trophoblastic malignancies and ectopically by other human cancers including carcinomas of the lung, breast, ovary, testis, and gastrointestinal tract and certain melanomas and lymphomas (1). The two subunits of hCG, a and (3, are frequently produced discordantly by tumors in vitro (2-4) and in vivo (1, 5, 6), a subunit production and secretion frequently being greater than that of the 3 subunit (2-4, 6). In addition, the prevalence of hCG-producing human cancers has been reported to be much greater when the tumor tissue itself was examined by radioimmunoassay than when only the blood was assayed: 10% of plasma samples from patients with various cancers were positive for hCG, whereas 42% of the tumor tissues from the same patients contained detectable amounts of hCG (7). The hCG subunits produced by human tumors have been shown to be heterogeneous by gel permeation chromatography (1, 8, 9) and isoelectric focusing (9), and differences in the Mr, amino acid composition, and reassociation with the 3 subunit have been observed between a subunit produced by tumors and normal placental a subunit (9, 10). These data suggest that diagnostic acuity could be increased for hCG as a biological marker of cancer, if the biochemical differences between ectopic hCG subunits and those produced by normal placenta could be determined and if the mechanisms controlling the secretion of hCG subunits from tumor cells could be established. This manuscript describes the synthesis and processing of hCG subunits in JAR choriocarcinoma cells as a model system to study these events. MATERIALS AND METHODS Radioactive Labeling of Cells. JAR choriocarcinoma cells were obtained from Roland Pattillo (Medical College of Wisconsin) and were grown at 370C in Dulbecco's modified Eagle's medium with 10% fetal calf serum (GIBCO). Confluent cell monolayers (100-mm-diameter petri dishes) were incubated for 20 min in Eagle's minimal essential medium or Dulbecco's The publication costs of this article were defrayed in part by page charge payment. This article must therefore be hereby marked "advertisemennt" in accordance with 18 U. S. C. §1734 solely to indicate this fact. 5143 medium lacking amino acids or glucose. Then they were incubated with the following radioactively labeled compounds: [a5S]methionine at 100 ,uCi/ml [500-700 Ci/mmol (1 Ci = 3.7 X 1010 becquerels); New England Nuclear] in methionine-free minimal essential medium (Flow Laboratories); '4C-labeled amino acid mixture at 50 MCi/ml (Amersham) or 3H-labeled amino acid mixture at 100 ,uCi/ml (Amersham) in minimal essential medium containing 1/10th the normal amino acid concentration (Flow Laboratories, McLean, VA); L-[4,5-3H]leucine at 100 ItCi/ml (53 Ci/mmol, Amersham) in leucine-free Dulbecco's medium (Associated Biomedic Systems); D-[63H]glucosamine at 100 ,uCi/ml (20 Ci/mmol, Amersham) or D-[1-3H]mannose at 200 ,uCi/ml (5 Ci/mmol, Amersham) in glucose-free Dulbecco's medium (Associated Biomedic Systems, Buffalo, NY). All incubations were carried out at 370C. In some experiments, the radioactivity was "chased" by removing the labeling medium, washing the cells three times with complete medium, and incubating for various times in the presence of complete Dulbecco's medium. After incubation, the medium was removed, and the cells were washed with phosphate-buffered (pH 7.2) 0.15 M NaCi and lysed by the addition of 5 ml of phosphate-buffered saline containing 1.0% Triton X-100, 0.5% sodium deoxycholate, and 0.1% sodium dodecyl sulfate (NaDodSO4) (lysis solution), followed by sonication. Medium was brought to the concentration of lysis solution by addition of a concentrated solution. Cell lysates were clarified by centrifugation at 100,000 X g for 1 hr. The 100,000 X g pellet contained no detectable hCG subunits by NaDodSO4/polyacrylamide gel electrophoresis followed by fluorography (see below) and so was discarded. Cell lysates and medium were stored at -70°C until analyzed. Immunoabsorption. hCG-specific polypeptides in the cell lysates and media were detected with rabbit antisera directed against intact hCG, hCG a subunit, and hCG-3 subunit polypeptides. Preimmune rabbit serum was used as a control. Immunoabsorptions were carried out by incubating up to 5.0 ml of lysate or medium with 1 ,tl of immune serum (1:5000 final dilution) at 40C for 16 hr and then precipitating the immune complexes by the addition of protein A-Sepharose CL-4B (Pharmacia) followed by mixing for 2 hr at 4°C and centrifugation at 1000 X g for 15 min. The immunoprecipitates were washed three times in lysis solution and then dissolved in 0.062 M Tris-HCI, pH 6.7/1% NaDodSO4/10% (vol/vol) glycerol/ 2.5% 2-mercaptoethanol. This solution was heated at 1000C for 5 min and then analyzed by electrophoresis as indicated below. NaDodSO4/Polyacrylamide Gel Electrophoresis. This was performed by the method of Laemmli (11) utilizing 5-20% linear gradient gels in a Bio-Rad model 220 slab gel apparatus for 16 hr at 35 V. Radioactivity was visualized by fluorography by the method of Bonner and Laskey (12). The following Abbreviations: hCG, human chorionic gonadotropin (choriogonadotropin); NaDodSO4, sodium dodecyl sulfate. 5144 Cell Biology: Ruddon et al. "4C-labeled Mr standards (New England Nuclear) were used: phosphorylase B (92,500), bovine serum albumin (69,000), ovalbumin (46,000), carbonic anhydrase (30,000), and cytochrome c (12,300). Digestion with Endoglycosidase H and D. Clarified cell lysates were incubated with endo-13-N-acetylglucosaminidases H and D (Miles) by the following procedures. Cell lysates containing approximately 1 mg of protein were diluted 1:10 into a buffer containing 0.1 M sodium citrate at pH 5.5 (for endo H reaction) or 0.15 M phosphate buffer at pH 6.5 (for endo D reaction); 0.1 unit of endoglycosidase H or D was added and the lysate was incubated for 6 hr at 370C. After incubation, the lysates were adjusted to pH 7.2 and immunoprecipitated as described above.


Recent developed application-level virtualization brings a groundbreaking innovation to Android ecosystem: a host app is able to load and launch arbitrary guest APK files without the hassle of installation. Powered by this technology, the so-called "dual-instance apps" are becoming increasingly popular as they can run dual copies of the same app on a single device (e.g., login Facebook simultaneously with two different accounts). Given the large demand from smartphone users, it is imperative to understand how secure dual-instance apps are. However, little work investigates their potential security risks. Even worse, new Android malware variants have been accused of skimming the cream off application-level virtualization. They abuse legitimate virtualization engines to launch phishing attacks or even thwart static detection. We first demonstrate that, current dual-instance apps design introduces serious "shared-everything" threats to users, and severe attacks such as permission escalation and privacy leak have become tremendously easier. Unfortunately, we find that most critical apps cannot discriminate between host app and Android system. In addition, traditional fingerprinting features targeting Android sandboxes are futile as well. To inform users that an app is running in an untrusted environment, we study the inherent features of dual-instance app environment and propose six robust fingerprinting features to detect whether an app is being launched by the host app. We test our approach, called DiPrint, with a set of dual-instance apps collected from popular app stores, Android systems, and virtualization-based malware. Our evaluation shows that DiPrint is able to accurately identify dual-instance apps with negligible overhead.


Statins have served as the cornerstone for cardiovascular disease(CVD)prevention.Some studies have shown that statins can reduce the risks of ischemic cardiovascular disease and ischemic stroke in patients with chronic kidney disease(CKD)by correcting dyslipidemia and its pleiotropic mechanism.In addition,there may be some changes in renal hemodynamics or the inhibition to the inflammatory response and so on,by which statins improve renal function or delay the deterioration of renal function.However,there were studies showing damage effects on the kidneys.So,there are needs for further understanding of statins in renal disease application and security to get objective assessment of their likelihood of damage to the kidneys.


Reaction of WCp(CO)3CCPh with Os3(CO)10(C2Me2) produced the butterfly cluster WOs3Cp(CO)10(CMeCMeCCPh)1 in moderate yield; treatment of 1 with Me3NO followed by thermolysis in refluxing toluene yielded the spiked triangular cluster WOs3Cp(CO)9(µ-H)[CMeCMeCC(µ2-η2-C6H4)]3 as a major product; on further thermolysis, complex 3 reconverted to a butterfly cluster WOs3Cp(CO)9[CMeCMeCHC(µ2-η2-C6H4)]5 and then to a tetrahedral cluster WOs3Cp(CO)8[CMeCMeCHC(µ2-η2-C6H4)]6via hydride migration followed by loss of CO; the structures of complexes 3, 5 and 6 have been determined by X-ray diffraction.


THE 1957 pandemic of Asian influenza was associated with a high attack rate and excess pneumonia mortality1; influenza-associated deaths were most common at the extremes of life. Although case fatality rates were low, the course of some cases was fulminant2 3 4 5 and comparable with the rapidly lethal variety of influenza observed in the pandemic of 1918–206 and in several subsequent epidemics.7 Recent reports of deaths associated with Asian influenza2 3 4 5 , 8 9 10 11 12 describe explosive, rapidly progressive and unresponsive respiratory failure frequently associated with staphylococcal infection, primary influenzal pneumonitis, neurologic and cardiac involvement, the rare isolation of Haemophilus influenzae from the respiratory tract and . . .


Two methodological approaches used to derive quality objectives to protect aquatic communities based on single-species tests will be described. Water quality objectives to protect aquatic life may be derived on the basis of ecotoxicological tests considering toxicity to bacteria, algae, (small) crustaceans, and fish. This spectrum of species comprises representatives of four trophic levels of water biocoenosis. The lowest no observed effect concentration value of the most sensitive specie is reduced by a safety factor (more appropriate: uncertainty factor) to extrapolate a "safe level" for the aquatic ecosystem. An alternative approach is the use of statistical extrapolation methods based on species sensitivity distributions to calculate maxium permissible concentrations. The approach using uncertainty factors will be compared with the approach using species sensitivity distribution to extrapolate safe levels. © 1994 by John Wiley & Sons, Inc..


High-energy x-rays as produced from one of the three large scale synchrotron sources world wide have the capacity to penetrate millimeters of stainless steel and thus it provides a suitable probe for bulk characterization. Further, the high brilliance of the x-rays enable kinetic studies and the possibility to probe the meso-scale structure such as single grains and dislocation structures embedded in the steels. The current paper provides an overview of the work conducted using synchrotron x-rays for structural characterization of stainless steels. Synchrotron x-ray characterization is also discussed in the light of other experimental techniques. We provide scientific examples of synchrotron x-ray diffraction studies on metastable austenitic and duplex stainless steel taken from our own work, and additional examples from the literature are given. When looking at the recently published literature many new insights in metal behavior have been gained by the utilization of synchrotron x-ray characterization. However, this type of research has only started and we predict more frequent usage and that these techniques will contribute significantly to the advance of our current understanding of polycrystalline metals, e.g. stainless steels.


Neurovascular regulation, including responses to neural activation that give rise to the blood oxygenation level–dependent (BOLD) effect, occurs mainly at the arterial and arteriolar level. The purpose of this study is to develop a framework for fast imaging of arterial cerebral blood volume (aCBV) signal suitable for functional imaging studies.

The paper focuses on the study of rational proper holomorphic maps from B to B . We classify these maps when N is the upper boundary point of the gap interval Ik, k ≤ n− 2 and the geometric rank of the map is k.


THOUGH A plenty of population and sectoral growth projections are available for the year 2001, only a few projections are available for the growth of the Indian economy as a whole in that year. As distinct from 'growth', hardly any futuristic exercises or predictions have been scientifically worked out for the 'development' of the economy. AdI1)ittedly, the latter exercise is rather difficult in view of the wide scope for value judgements involved in it, over and above its inherent technical and methodological difficulties. Even for growth projections, there are plenty of methodological difficulties owing to the non-spontaneous, planned, and sponsored nature of the phenomenon of 'growth' in our economy. Since 'growth' (sustained and substantial· increase in national income, a la Kuznets) is a planned affair, the projections will have to be based on a whole set of assumptions concerning economic policy, planning, and the mechanisms of implementation. As the Base Document on Futurology (Department of Science and Technology, Government of India) rightly pointed out


The micro-morphology of the interface transition from (012) facet to freezing isotherm curve has been observed. In the centre of the interface (the high supercooling region), the morphology of (012) facet shows characteristics of terrace-step-kink structure. By reducing supercooling, the growth interface gradually turn to agreeing with the freezing isotherm curve.


This work marks the first use of phase spectra detection method to realize selective sensing of chemical vapors on a chemical vapor deposition (CVD) monolayer graphene field effect transistor (FET). Compared with the state-of-art technology, three distinctive advances have achieved: (1) first demonstration of selective gas sensing using the phase spectra detection method on a single CVD graphene FET without surface functionalization; (2) first demonstration of quantitative phase spectra detection results for four gas vapors (water, methanol, ethanol and isopropanol) with different concentrations; and (3) illustrations of the sensing selectivity by the extraction of phase spectra features with experimental validations by using the principal component analysis (PCA) scheme. As such, the proposed method of phase spectra detection can achieve gas sensing selectivity without surface functionalization or an array of devices.


The nasal route of drug administration, as is well known, is characterized by some advantages: absorption rate and rapid onset of therapeutic effect, availability of drug delivery without hepatic first-pass elimination, it is suitable and easily accessible. Earlier a medication for nasal administration with noopept – a low toxic substance with peptide nature without any side effects and high activity has been developed. After advance investigations, a solution of sodium carboxymethylcellulose providing the highest rate of noopept releasing was chosen as a delivery base. The aim of work the study of surfactants' influence on the noopept releasing from the nasal dosage form. Materials and methods . For the investigation, the compositions containing twin-80 from 0 % to 3 % were prepared. Surfactant was added to the nasal dosage form containing noonpept 1 %, glycerol, and bishofit poltavsky equally by 5 % and solution of sodium carboxymethylcellulose. Noopept releasing was studied using the method of equilibrium dialysis by Kruvchinsky through the semipermeable membrane – cellophane film "Kuprofan" after 30 minutes. Noopept concentration was determined by the UV-spectrophotometry at 258 nm.  Results . Results of investigation have verified that the addition of twin-80 to nasal dosage form with noopept provides with a better level of releasing of the active substance. At the same time, increasing of concentration more than 1 % hasn't a significant influence on the noopept releasing. Conclusions . It was determined that the content of twin-80 has a significant influence on a noopept releasing from the nasal dosage forms. The concentration of twin-80 1 % provides optimal releasing.


PurposeThis paper aims to illustrate some of the negative heritage created in Syria over the 11 bloody years following the start of the uprising in 2011 and how this heritage can be managed to promote justice.Design/methodology/approachDifferent motives and methods for negative heritage management are exemplified and compared to find out the most appropriate one(s) that can be adapted and adopted in the Syrian context. Based mainly on Human Rights Watch (HRW) reports, suggestions are made for the management of three cases of negative heritage in Syria by planning measures and solutions to promote justice. The three cases are the targeting of schools and hospitals, chemical attacks and Aleppo's River Massacre. The effectiveness of the proposals is discussed and piloted by conducting a one-on-one conversational interview in 2021, related to the first proposal, and soliciting feedback on a social media platform, related to the third proposal.FindingsValues-centred preservation based on the efforts of the community concerned with negative heritage, rather than the four existing governments in Syria, can lead to good management of recent negative heritage. The proposed virtual application of the proposals is a step that may itself be useful and may facilitate future practical application, as most of the exemplified sites are no longer accessible on the ground.Originality/valueEthically productive management of the negative heritage is promoted to seek more value-oriented dimensions of the conflict. Considering a fruitful use of the conflict in Syria can encourage positive thinking and counter the passive attitude towards the prolonged conflict.


Bionic wavelet transform is a continuous wavelet, based on adaptive time frequency technique. This paper presents a speech recognition system for recognizing isolated words by discretizing the continuous Bionic Wavelet (BW). Conversion from continuous to discrete is achieved by adopting central frequency and thresholding techniques. The BW features of noisy signal are processed through MFCC to obtain the optimal features of the speech signal. SVM, Artificial Neural Network (ANN) and LSTM techniques are used to improve the recognition rate by enhancing the speech signals. The experiments are conducted on FSDD and Kannada data set. The speech feature vector is calculated using the parameters extracted by Bionic wavelet with different central frequencies of Morlet, Daubechies and Bior3.5, coiflet5 mother wavelets. The obtained Bionic-MFCC optimal features are fed to SVM, ANN and LSTM models for the classification and recognition process. The performance of the models is tabulated for correct recognition that varies from 95% to 96% among these models. The models are tested for various SNRs noise levels like 5 dB, 10 dB, 15 dB and the recognition accuracies of these models are presented for convoluted noisy speech data.


The role of heme-regulated eIF-2a kinase (HRI) in the regulation of protein synthesis in rabbit reticulocytes is well documented. Inhibitors of protein synthesis with properties similar to those of HRI have been described in some nonerythroid cell types, but it has not yet been determined whether these eIF-2o kinase activities are mediated by HRI or one or more as yet uncharacterized kinases. We have studied the expression of mRNA, polypeptide, and kinase activities of HRI in various tissues from both nonanemic and anemic rabbits. Our results indicate that HRI is expressed in an erythroid cell-specific manner. HRI is present in the bone marrow and peripheral blood of both nonanemic and anemic rabbits but not in any of the other tissues tested. HRI mRNA is present at low levels in uninduced mouse erythroleukemic (MEL) cells and human K562 cells and accumulates to higher levels upon induction. The accumulation of HRI mRNA in differentiating MEL cells is dependent upon the presence of heme. The addition of 3-amino-1,2,4-triazole (AT), an inhibitor of heme biosynthesis, to the induction medium markedly reduced HRI mRNA accumulation. Simultaneous addition of hemin and AT to the dimethyl sulfoxide induction medium largely prevented the inhibition of HRI mRNA induction by AT. These findings indicate that HRI is expressed in an erythroid cell-specific manner and that the major physiologic role of HRI is in adjusting the synthesis of globins to the availability of heme. 1134 of the mouse NF-E2 cDNA, respectively. These primers define a fragment 226 nucleotides in length for HRI and 834 nucleotides in length for NF-E2. Reactions were carried out for 35 cycles with 2 min at 94°C, 2 min at 4TC, and 3 min at 72°C in the presence or absence of Perfectmatch (Stratagene). Reaction products were separated by electrophoresis through a 1.0% agarose gel and visualized by ethidium bromide staining.


ISSN 1948-6596 news and update book review If the conceptual straitjacket fits, chances are, you're already wearing it Molecular Panbiogeography of the Tropics. Michael J. Heads, 2012, University of California Press. 565 pp. $75.00, £52.00 (harback) ISBN: 9780520271968; http://www.cambridge.org This is part of a series of volumes aimed at, in the words of its editors, examining "the role of de- scriptive taxonomy, its fusion with cyber- infrastructure, its future within biodiversity stud- ies and its importance as an empirical science." The author's stated intention is to attempt to demonstrate "patterns of community immobilism leading to allopatric differentiation, as well as other patterns of mobilism, range expansion, and overlap of taxa." It was with these themes in mind that I delved into Heads' latest work. But first, in the spirit of full disclosure, I have encountered the author of this book, as well as several of his fellow panbiogeographers, from the New Zealand as well as the New York schools of the subdiscipline, which together comprise a vocal minority in biogeography. My interactions with the panbiogeographers have come via a number of academic exchanges, each of which has unofficially ended in an understood 'agree to dis- agree', intellectual truce. Receipt of this review request generated feelings of both hesitancy and curiosity. I was hesitant to spend time on this topic because each prior exchange with Heads and his associates has boiled down to the willingness on my part (and that of our colleagues in main- stream phylogeography), to approach bio- geographic data from a perspective that is open to both dispersal- and vicariance-based interpreta- tion. By contrast, panbiogeograpers strongly re- ject the significance of dispersal a priori, in any form. Based on past interactions and published exchanges with this group (e.g., Holland and Cowie 2006, Nelson 2006), a clear way forward in this dialogue has yet to materialize. My curiosity came from the chance to evaluate this recent of- fering, being due in part to my admitted lack of appreciation of the usefulness of panbiogeogra- phy, and the possibility that my views might change given the "new" panbiogeographic per- spective promised in the Preface. Perhaps a brief refresher on the nuts and bolts of the field is warranted, since panbio- geographic reasoning can be perplexing for a number of reasons, not the least of which is that its proponents have created their own terminol- ogy. The field was proposed by Leon Croizat in 1958, and furthered by M.J. Heads as well as R.C. Craw and J. Grehan. Panbiogeography was defined by Craw et al. (1999) as a method whereby known species distributions are first mapped and then extended by drawing connecting lines on maps. Lines are termed 'tracks' and are drawn such that they 'connect' collection localities or disjunct dis- tributions of a particular taxon. Multiple overlap- ping tracks for unrelated taxa form 'generalized tracks'. The figures presented in the new book consist of dozens of black-and-white maps with lines and shapes superimposed to indicate distri- bution patterns. Croizat was correct and ahead of his time in realizing that speciation can occur after emer- gence of a barrier within the existing boundaries of a distribution, a phenomenon that ultimately became known as vicariance. But this somehow led him, and the panbiogeographic movement which followed, to vehemently deny, a priori, any role of dispersal in natural history. Croizat (1964) stated "I intend to destroy these notions (pertaining to 'means of dispersal') because they positively interfere with the advance of knowl- edge on far-reaching points of evolution over space, in time, by form" (p. vi). This vague notion of evolution in space and time by form is repeated frequently in panbiogeographic publications. Ac- cording to Cox and Moore (2005) "Even after the theory of plate tectonics had been well docu- mented and widely accepted, Croizat refused to accept it, and never integrated it into his method- ology" (p. 31). Heads also expresses a refusal to © 2012 the authors; journal compilation © 2012 The International Biogeography Society — frontiers of biogeography 4.4, 2012


This report is concerned with the birds of prey which use the Hanford Site not only during the nesting season but throughout the year. An ecological treatment of five nesting owls (great horned, long-eared, short-eared, barn and burrowing) and five nesting hawks (marsh hawk, red-tailed hawk, Swainson's hawk, prairie falcon and American kestrel) is provided and supportive information on non-nesting species is presented. Factors which control raptor densities and population dynamics throughout all seasons of the year are discussed. Information is also provided for raptors from other areas of southcentral Washington in order to yield a comprehensive picture of how the Hanford Site fits in with regional bird of prey populations. The following were the objectives of this study: (1) to determine the numbers of birds of prey nesting on the Hanford Site, (2) to document the reproductive chronology of each nesting raptor species, (3) to provide analyses of food habits of birds of prey on the Hanford Site coupled with prey abundance data, (4) to determine the productivity of the dominant large birds of prey on the Hanford Site, (5) to determine the distribution and land use patterns of all raptors on the Hanford Site, (6) to determine themore » kinds and relative abundance of non-nesting raptors on the Hanford Site and adjacent areas of southcentral Washington (7) to document present land use practices on the Hanford Site and their effects on raptors, (8) to document radionuclide levels in birds of prey on the Hanford Site, and (9) to determine the role of birds of prey in radioecological monitoring.« less


It may be that these two types of symptoms are able to be dissociated based on pathology or pathophysiology. Studies have typically associated orbitofrontal-basal ganglia connections in the presence of depression in PD, whereas anterior cingulatebasal ganglia connections are suggested in the presence of apathy. It is possible that PD subjects with apathy in the absence of depression have more pathological involvement of the anterior cingulate than the orbitofrontal area, but this remains for future investigation.


Abstract Maps are fundamental in geographic explanation and education, but as map-making becomes firmly entrenched in the GIS lab, it becomes harder for students to imagine how they can make maps for their papers. Students need to illustrate papers with maps: among other things, maps provide clarity, links to real places, and insights into patterns and context of phenomena discussed in student papers. A simple, quick, and aesthetically satisfying method for students to make their own maps is presented. This map making method can help students can think more creatively and geographically about their topics.


Animal characteristics are needed for calculation of nutrient requirements and IC for both cows and growing cattle. Information on animal parameters, such as BW, is also needed when calculating ruminal variables, such as passage rates of feed fractions out of the rumen and efficiency of microbial protein synthesis. Moreover, the physical activity of the animal (simply classified according to whether it is loose or tied up) will affect the IC and energy requirements.


Objective To investigate the effects of pyruvate on the cardiopulmonary bypass(CPB)-induced myocardiocyte apoptosis in dog and its role in modulation of fas,fasL,bcl-2,bcl-xl,bax,bad and caspase-3 pathways. Methods Ten healthy adult male and female dogs undergoing conventional CPB were randomized into control and pyruvate treated groups(each n=5).Pyruvate was used in the latter group to maintain a concentration of 2 nmol/L in plasma and cardioplegic solution.Samples of the left ventricle(LV) were obtained before,during and 3 h after CPB and stored in liquid nitrogen until assay.In situ TUNEL technique was used to detect the apoptotic cells and the number of apoptotic positive cells per 105 myocytes was counted.The expression of fas,fasL bcl-2,bcl-xl,bax and bad was semi-quantified by flow cytometer technique.The activity of caspase-3 measured by cleavage of Z-DEVD-AMC substrate.Level of Malondiadehyde(MDA) in the myocardium was measured by thiobarbituric acid reactive substances(TBARS) method. Results All the parameters before and during CPB had no significant difference between intra-and enter-groups.After CPB,the number of apoptotic cells in both control and pyruvate treated groups were significantly increased compared to that before and during CPB(P0.003,0.003,0.001 and 0.001,respectively),and the number of apoptotic cells in pyruvate treated group was remarkably reduced compared to control group(P=0.019).Expressions of fas,fasL,bax and bad proteins and the activity of caspase-3 were also significantly upregulated in both groups after CPB compared to those before and during CPB(P0.025,respectively),and were significantly inhibited in pyruvate treated group(vs control P0.05,respectively).While the expressions of bcl-2,and bcl-xl had no significant difference before,during and 3 h after CPB in both groups.The content of MDA in the LV myocardium after CPB were also elevated in both groups compared to those before and during CPB(P0.001,0.003,0.001 and 0.001,respectively) and was significantly inhibited in pyruvate treated group compared to control group(P0.015). Conclusion Treatment with pyruvate can significantly reduce cardiomyocyte apoptosis,down-regulate the expressions of fas,fasL,bax and bad proteins and inhibit the activity of caspase-3 and the production of lipid peroxide in dog hearts following conventional CPB.


Alkaline corrosion of aluminum results in large supersaturations of hydrogen, and formation of hydride and subsurface voids.1-4 Aluminum itself is not susceptible to stress corrosion cracking (SCC), but hydrogen and hydride effects are significant for SCC mechanisms on Al and Mg alloys. Chu found evidence that corrosioninduced tensile stress in several alloys additively combines with external tensile stress to promote SCC, and attributed the former to lattice contraction associated with vacancies injected during corrosion.5 Evidence for vacancy injection on Al was found from X-ray diffraction and in situ curvature measurements on Al thin films undergoing corrosion.1,6 Here we report new measurements of stress evolution on Al sheet samples, over longer times than was possible with thin films. Also, we describe a model that provides a unified quantitative explanation of diverse experimental observations: electrochemical transients, stress measurements, hydrogen absorption detected by SIMS and void formation measured by positron annihilation spectroscopy (PAS).


Vulvar involvement was found in ten (18%) of 53 females with von Recklinghausen's disease. Vulvectomy was necessary in only two of these ten patients. In distinguishing elephantiasis nervorum of the vulva from an intersex problem, the presence of cafe au lait spots and a familial history of neurofibromatosis are helpful clues.


College counselor is a group specialise in students' moral education. As the main power to manage college students, they guarantee the construction of socialism's erector and successor who develop morally, intellectually and physically .In the present situation, analyzing the experience has a practical meaning in strenghening counselors constructoin.


The term "variety" has historical precedence over "subspecies" and is either prescribed or recommended by the ICBN as the rank to be first used in the description of infraspecific taxa.The rank "subspecies"is then used to cluster related varieties. Accordingly, to replace earlier combinations at subspecific rank, the following new combinations in Styrax platanifolius are proposed: var. mollis (P.W. Fritsch) B.L.Turner,comb.et stat.nov.;var.texanus (Cory) B.LTumer,comb.et stat.nov.;and var. youngiae (Cory) B.L.Turner, comb. et stat.nov.No subspecies are recognized here in S.platanifolius.


In the strictest sense the upper beach is not a portion of the beach at all, since it is beyond the reach of the waves; it might perhaps be called a fossil beach, but the fact that it is continuous with the beach proper seems to exclude that term, as does the recency of its fossilization. The expression fossil beach will be reserved for a formation of greater geological age and separated from the present beach by other topographic forms. Where dunes are superposed upon the beach, the upper limits of this third beach zone are quite vague, though the theoretical line of demarcation is where the sand is first accumulated by the wind. Where clay bluffs are present at the water's edge, the beach is quite narrow and the upper limit fairly well defined, though at times obscured by alluvial fans. Occasionally the upper beach approaches very close to the water's edge; this is the case where the lower and middle beaches are very narrow because of a high gradient. Sometimes the lower or middle beach zone is replaced by a tiny cliff; in such a case the upper beach may approach to the edge of this cliff. The limits of the upper beach, as of other beach zones, are constantly shifting. The lower limits are carried lakeward or landward by the waves of winter storms, but on the whole the lower limits are pushed out more and more lakeward, keeping pace with the advance of the lower beach. The shifting of the wind causes variations in the upper limits, but on the whole the dunes likewise are commonly formed more and more lakeward, as will be shown further on. The three beaches, then, shift from year to year with apparent irregularity, but there appears to be as a resultant a general pro-


Initiatives have been undertaken in Europe in order to increase the number of university students and graduates. Initiatives have been made undertaken in Europe in order to increase the number of university students and graduates from higher education institutions. Each country emphasizes different aspects of the problem. However, it is common to stress the need for the higher number of university students from "non-traditional" environments, and from the standpoint of both European and world universalism, the environment of the deaf should be considered as such. Study aim: The aim of the study was to evaluate adjustments made at universities to aid the educational process of people with hearing impairments in comparison to adjustments introduced for other forms of disability. The study was based on a diagnostic survey. The exclusion criterion concerned only the universities that did not agree to participate and/or had never educated students with disabilities.
The results of the study did not support the research thesis showing that the profile of a university is a significant factor of choice for people with hearing impairments. It was demonstrated that the number of deaf university students is decreasing with time despite statutory deregulation which involved a removal of certain legal barriers. The amendment to the Higher Education Act eliminated legal barriers, but the universities are challenged with the implementation of the regulations in the academic practice.


A double tube phase change material (PCM) storage is investigated. The thermal energy storage (TES) contains a polycarbonate shell filled with paraffin wax and a copper tube to carry heat transfer fluid (HTF).The fusion takes place radially outwards from the center. Ineffective melting of wax was observed in bottom due to temperature gradients. An increase in HTF inlet temperature by 5°C reduces the melting time by 6.2% and increases the efficiency by 3.9%. Effect of mass flow rate of HTF is comparatively lower than HTF inlet temperature towards complete melting of PCM.


The invention relates to a ventilator for intensified breathing, whereby a restrictor valve for an over-pressure in the system, a valve allowing breathing from the atmosphere and a directional valve for inhalation are combined to provide a single safety valve (21) arranged in a gas mixture and inhalation conduit assembly (7, 8), said safety valve being arranged to be controlled by an electric control system (26) of the ventilator. The invention also relates to a valve of the above type.


Since their return to power in august 2021, Taliban leaders have not articulated a clear vision of how they plan to structure the afghan state. Some observers have expressed guarded optimism that the Taliban can be persuaded by interlocutors from the international community and from afghan civil society to move away from some of the most authoritarian and illiberal aspects of their first regime. This report is intended to help these negotiators by identifying the core Taliban attitudes toward the legitimacy of a constitutional order from a doctrinal religious perspective and by offering suggestions for how actors that engage the Taliban can work within those areas to find possible compromises between the Taliban's vision of "true" Islamic governance and liberal democracy.


The duellings at 2503-05-07 Eye Street form a unique group within the district. Designed in 1892 by Thomas Francis, Jr. for T. 8. Harrison, they boast large projecting square bays. These buildings present a forthright appearance uith their massiue bays and strong uertically set brick cornices. The original windows haue been replaced. The row of duellings along 25th Street is typical of the district. Numbers 912,912V2,914, and 914V2 are distinguished by the uaried placement of entrance doors. All four buildings are tuq stories high and three bays uide. Designed in 1887 as a speculatiue project by B. H. Uarner and Company, they uere originally used as single family residences. Number 91Zis particularly notable because it retains the original door location and has fine proportions. An intricate stepped brick cornice crouns the group and segmental arches ouer the uindous are accentuated by pressed brick detailing. The emergence of alleys as duelling areas was due to the urban housing shortage in the middle of the nineteenth century. The first documented alley structures in Washington date back to approximately 1850. This initial phase of alley building consisted primarily of flimsy shanties and sheds, offering the "barest protection. The great influx of ex-slaues, soldiers and uagrants following the dull UJar further exacerbated the housing problem and prouided a strong stimulus for alley deuelopment. In the period from 1870-1892, substantial frame and brick rowhouses began to appear in large numbers and close-knit alley communities comprised of unskilled workers and uagrants came into being. The dwellings were the first of their kind to appear in an alley and serued as forerunners for the frame rowhouses 1870s. Ciuil Snow's houses were used as army barracks; the war, Snow's alley deueloped at the same rapid rate as other alleys. A 1938 study a uery high rate of resident stability, with more than half hauing liued in the alley for ouer flue years.


Tokyo Gas has developed a compact and high-efficiency cogeneration system which can run with the mixture of biogas and natural gas, based on a new concept. To utilize the biogas whose amount of production varies from time to time, we have developed a gas mixture system that utilizes as much biogas as possible under simple and reliable control. Also, we have developed an air dilution system of natural gas to maintain stable combustion at the engine. Due to this system, the mixture ratio of biogas and natural gas can be anything from 0% to 100%. Further more, since this system is equipped with multiple safety measures, cogeneration system can continue its operation even after any thinkable malfunctions of the system. This gas mixture system and cogeneration plant has been installed at a beer brewery near Tokyo, and operating without any major troubles.Copyright © 2005 by ASME


Low-income households derive significantly less savings from mortgage refinancing than their wealthy counterparts. I document that the rise of refinancing inequality in the United States can be partially explained by the gap in access to modern information and communications technology. Using granular spatial variation of a large-scale broadband subsidy program, I show that high-speed internet facilitates refinancing activity and reduces monthly mortgage payments. These effects are large and persistent, corresponding to a 5 percent increase in disposable income and up to $18,000 in total savings for low-income households. The growth of refinancing is pronounced in underserved areas with low access to bank branches and among populations that are likely to have low financial and digital literacy. ∗UCLA Anderson School of Management.

The invention belongs to the technical field of medical instruments, and achieves a sputum suction device with a breath simulating function. The content mainly relates to the method that through simulating of breath of a patient, influence on work of a breathing machine in the working process of the sputum suction device is avoided. The sputum suction device is different from a traditional sputum suction device, the sputum suction device and the breathing machine are connected to a breathing circuit of the patient in parallel, through the self learning function of the sputum suction device, the mechanical ventilation characteristic of the patient is learned, and through simulating of a breath process of the patient, the influence on the breathing machine due to the cutting off of mechanical ventilation circuit is avoided in a sputum suction process of the sputum suction device. The sputum suction devices simulates the breath process of the patient, the influence on the breathing machine due to the cutting-off of mechanical ventilation circuit is avoided in the sputum suction process, influence on mechanical ventilation by the patient after the sputum suction is reduced, and therefore the sputum suction device has excellent popularizing prospects.


In many countries significant amounts of public funding are devoted to supporting firms' R&D and innovation projects. Here, using panel data on the innovation activities of Irish manufacturing firms we examine the legacy effects of public subsidies for new product development and R&D. We examine five alternative mechanisms through which such effects may occur: input additionality, output additionality, and congenital, inter-organisational and experiential behavioural additionality. Tests suggest contrasting legacy effects with R&D subsidies generating legacy output additionality effects while new product development subsidies have legacy congenital and inter-organisational behavioural additionality effects. Our results have implications for innovation policy design and evaluation.


prepared The compound rubber material by reinforcing it with nanoparticle powder (N Pb) for protective shields in hospital X-ray units for the purpose of protecting fetuses from congenital deformity in pregnant women and workers in X-ray rays. The addition of chlorophyll extracted from tree leaves and plants as a plasticizer and anti-oxidant with different ratios of (20 - 100 pphr) and (20 pphr) was chosen as a percentage that achieves the purpose, but prevented it from penetrating the X-ray radiation is very little even at high ratios, as well as TiO_2 of (20 - 100 pphr) was added. 20 as a micro-filler for the purpose of obtaining good mechanical properties such as tensile strength, elasticity and hardness with different ratios (20 -100 pphr). 20 pphr was chosen as a ratio that achieves the purpose, but it prevents it from penetrating the X-ray rays. Very few even at high ratios. And by adding nanoparticles lead (40 – 350 pphr) good results in cutting the radiation penetrate the X-ray and the best ratios (100, 200, 300, 350 pphr) as adding (100 pphr) of N Pb to the rubber with a thickness (2 mm) the rays were penetrated and cut at (60 KV). Whereas, adding (200 pphr) of N Pb to the rubber with a thickness of (2 mm) prevented the penetration of X-Ray rays and cut them at (80 KV). Whereas, adding (300 pphr) of N Pb to the rubber with a thickness of (mm3) prevented the penetration of X-ray rays and cut them at (100KV). Whereas, adding (350 pphr) of N Pb to the rubber with a thickness of (3 mm) prevented the penetration of X-Ray rays and cut them at (110KV). In this way, the purpose of protecting the fetuses of pregnant women when they are exposed to radiation in the X-Ray units and their workers when using this material as a cover or shield with a thickness of (3 mm) was achieved.


Workers in the construction, agriculture, hotels and restaurants are most likely exposed to heavy loads as manual handling occurs in almost all working environments. To alleviate this problem issuance of handling aid was introduced in different industries. Continuous lifting and handling activities may gradually cause cumulative disorders which can also cause acute trauma such as cuts or fractures due to accidents. Low back pain and injuries are considered as one of the most common musculoskeletal disorders caused by lifting. However, there are several factors that contribute to the increase of risk of workers and these includes distance to be travelled, load weight to be carried, human attributes such as age, body weight, gender, and height. Controlled simulation of present and proposed design of wheelbarrow was done in order to analyse the problem and improvements respectively. Binomial Logistic Regression was performed to assess if the identified factors that might influence the likelihood of incurring pain in different body region are valid. Questionnaire was also used based on comfortability, ease of usage, and safety of the wheelabarrow; the questionnaire was performed for the current and proposed design in order to assess its perfomance and identify if there are significant differences between the two designs using Chi-square test. Failure Mode and Effect Analysis served as an efficient method in the risks involved with the use of the product. And lastly, ergonomic principle were applied to appropriately dimension the height, handle-to-handle gap, and grip diameter of the handle by applying the concepts of Anthropometry.


abyssinica grown in two variants (with and without herbicides). In addition, the quality of by-products (straw and cake) as energy feedstocks was evaluated. Costs of production of Crambe abyssinica seeds in the variant with herbicides were nearly 140€·ha-1 higher than in the variant without herbicides. The yield of pure seeds was by over 110kg·ha-1 higher in the herbicidetreated variant than in the treatment without weed control. However, the yield of straw was higher on fields without application of herbicides, but that straw had a higher moisture content due to the presence of weeds. The lower heating value of crambe straw was 15.3MJ·kg-1 on average and the straw content of ash was 5.68% D.M. The cake obtained from the crop had a much higher lower heating value (21.95MJ·kg-1) and ash content 6.41% D.M. Moreover, it was found to contain much more carbon and hydrogen, as well as five-fold more sulfur than straw. Production costs and residues evaluation of Crambe abyssinica as an energy feedstock*


Abstract The geographic skills, as outlined in Geography for Life, provide an avenue for assessing students' work in geography. If used across the scope and sequence of the curriculum, a common scoring guide based on these skills offers opportunities for students to demonstrate their ability to use inquiry approaches to study geography and to improve those abilities over time and over different geographic questions. If used consistently, a geographic skills scoring guide can also help to communicate to a broader audience of parents, administration, and the public as to what the discipline of geography encompasses.

We report the synthesis of carbon nanodots (Cdots) from watermelon peel waste. The Cdots obtained were characterized using ultraviolet-visible, photoluminescence, Fourier-transform infrared spectroscopies, and transmission electron microscopy. The Cdots exhibited green luminescence. The average diameter of the Cdots was 4 nm and the C=C functional groups were dominant. The Cdots were then utilized as CO2 absorbent in biogas. The result showed that the concentration of CO2 was reduced by up to 40% based on the gas chromatography test. The higher the Cdots concentration, the higher is the amount of CO2 that can be reduced in the biogas. Based on the heat performance test, higher concentration of Cdots produced higher heat energy of the biogas.


This study explores the lived experiences of primary school teachers in implementing inclusive education, in order to further understand the challenges faced by the teachers, strategies they employ, and forms of support they need. The data was obtained through one-on-one semi structured interviews. Six mainstream primary school teachers who have experienced teaching students with special educational needs (SEN) participated in this qualitative study. Data from the interviews was organized and coded using QDA Miner Lite software and Hycner (1985) data analysis process was applied as a guide in the analysis of data. Findings of the study show that teachers' attitude towards inclusive education was generally positive. However, the teachers were unsure of how to implement inclusive education due to inadequate training, exposure, and knowledge in regards to the concept and practice of inclusive education. The participants suggested that positive, supportive and accepting attitude of teachers towards students with SEN is very important for a successful inclusion program. The teachers requested additional training, effective collaboration with special education experts, more effective teacher-parent relationship and early intervention of students with SEN as support structures needed to boost confidence to teach in an inclusive classroom. Several implications are drawn from the findings and some recommendations for professional practice and further research on inclusive education are provided in the final chapter of this study.


Four energization switching devices and positive/negative switching devices are controlled to form a path charging a positive capacitor; a path connecting a power supply with the positive capacitor in series and energizing an inductor to charge a control terminal of a target switching device; a path charging the control terminal using electromagnetism in the inductor; a path supplying circulating current to the power supply when potential of the control terminal becomes higher than voltage of the power supply; a path charging a negative capacitor; a path connecting the power supply with the negative capacitor in series and energizing the inductor to discharge the control terminal; a path discharging the control terminal using electromagnetism in the inductor; and a path supplying circulating current to the power supply when potential of the control terminal becomes lower than potential of a negative terminal of the power supply.

Studying of languageimpoliteness is very important to avoid verbal bullying insocial media.


Feedstock production for large scale development of the U.S. ethanol industry and introduction of cellulose–to-ethanol technology will require extensive changes in land use and impact water demand and quality. This study compares two scenarios: attaining a 60 billion gallon per year target of ethanol by 2030 and a billion gallon per year biodiesel target by 2012 with cellulose-to-ethanol technology introduced in 2012 and also delayed until 2015. Results suggest water demands and quality will vary regionally with cellulosic feedstock production. Policy emphasis on reduced and no-till practices needs to be complementary to increased crop residue use.

The relocation of manufacturing professions in favour of low-wage countries have been a frequent discussion lately. Today we see the trend develop even further, towards relocation of business processes. One of these business processes that have been up for discussion in recent times is Research and Development, RD respondents working outside companies, respondents working inside companies, and respondents working close to companies we gained information about the subject in matter and distinguished six areas from were useful information could be gathered in order to fulfil the purpose of the study; the offshore trend, R&D internationalization, cost versus quality, competence/knowledge, networks, and opportunities and threats. There is no ensured knowledge of the internationalization proportions but there is still a tendency to relocation of companies. However, this also lead to an increased number of foreign owned companies in Sweden, which may result in a wider and deeper knowledge base in the country. The difficulties in transferring knowledge seem to be an issue and while low-wage countries' competence increases there might be in question to relocate part of R&D units. It is therefore of huge importance to stay flexible and responsiveness to be able to stay competitive at the global market. Further net-works play an important role when competing globally since these may contribute to increased knowledge and better opportunities. The chase towards decreased costs and increased competence will always be a fact. However, the most important during today's international changes and the new reality is to not interpret the changes as threats but as opportunities.


The invention provides a horseshoe completely laminated with a horse's hoof face and a manufacturing method therefor. The horseshoe comprises an upper component and a lower component which are connected vertically, wherein the shape of the upper surface of the upper component is matched with that of the horse's hoof face, and a plurality of upper nail holes are further dispersed in the upper component along contour edge; and the lower component is of a U-shaped structure and has a plurality of lower nail holes corresponding to the upper nail holes of the upper component. The upper component is made from iron, aluminum alloy, steel or titanium alloy; and the lower component is made from titanium alloy. According to the manufacturing method, the actual geometric morphology of the horse's hoof face is scanned by using a three-dimensional scanning technique, and the surface morphology of the upper component of the horseshoe is printed by using a metal three-dimensional printing technique. According to the horseshoe completely laminated with the horse's hoof face and the manufacturing method therefor, the lower component in friction with the ground is manufactured from a wear-resistant material, and a geometric contact face which is completely laminated with the horse's hoof face is provided, so that the frequency of replacement of the horseshoe can be lowered, and then, the possibility that horse's hooves are full of nail holes and are injured due to hoof nail nailing is lowered.


Indonesia has agreed to the ASEAN Consensus on the Promotion and Protection of the Rights of Migrant Workers. However, many cases have proved the vulnerability of the legal protection for Indonesian migrant workers in Malaysia. In other words, the consensus has not protected the workers. Therefore, this research was conducted to analyze considerations for the regulations designed to protect post-consensus migrant workers. The objective comprised three aspects: analysis of the legislation after consensus, the draft policy that realizes the consensus, and the enforcement based on the draft formulated to safeguard the rights of migrant workers—a normative juridical method used in this research. The results showed that the consensus is a soft law that does not have a binding effect and sanction, causing it vulnerable to a violation, especially among undocumented migrant workers.  Therefore, the research recommends bureaucracy reform to reduce the administrative costs for the migrant workers, allowing them to have better legal protection.


: Complex phenomena of our world cannot be successfully explored from the perspective of isolated fields of science. What is therefore needed is a synthe-sizing approach. The cooperation of a multidisciplinary team at a primary school should be focused on the identification and elimination of the problematic areas of education. The establishment and support of multidisciplinary teams requires strategic planning by a school management. Any such team should approach pupils' needs in a coherent way. This paper concerns the effects of the education program and identifies strong and weak points in cooperation of multidisciplinary team members at primary schools. The author presents the results of a survey – in-depth structured interviews with managers of primary schools participating in the education program Cooperation of pedagogical employees and specialists in the system of inclusive pupil support within the governmental project School open to everybody .


The recent interest in modeling complex networks has fueled the development of generative graph models, such as Kronecker Product Graph Model (KPGM) and mixed KPGM (mKPGM). The Kronecker family of models are appealing because of their elegant fractal structure, as well as their ability to capture important network characteristics such as degree, diameter, and (in the case of mKPGM) clustering and population variance. In addition, scalable sampling algorithms for KPGMs made the analysis of large-scale, sparse networks feasible for the first time. In this work, we show that the scalable sampling methods, in contrast to prior belief, do not in fact sample from the underlying KPGM distribution and often result in sampling graphs that are very unlikely. To address this issue, we develop a new representation that exploits the structure of Kronecker models and facilitates the development of novel grouped sampling methods that are provably correct. In this paper, we outline efficient algorithms to sample from mKPGMs and KPGMs based on these ideas. Notably, our mKPGM algorithm is the first available scalable sampling method for this model and our KPGM algorithm is both faster and more accurate than previous scalable methods. We conduct both theoretical analysis and empirical evaluation to demonstrate the strengths of our algorithms and show that we can sample a network with 75 million edges in 87 seconds on a single processor.


– The comminution in Semi-Autogenous (SAG) mills depends on the impact conditions. It will be worthwhile to determine the efficient impact parameters. Drop weight test is employed to simulate the ball-flat impacts and study the effect of collision energy on ore breakage. Specimens are the copper ores of SAG mill feed of Sarcheshmeh copper complex. Minimum energy required for breakage is determined for each size. The size distribution of the broken ore due to the different specific input energies is determined and a relation is presented to predict it. Since the production of fine particles is important in SAG mill process, t 10 is measured and discussed. The results of present work can be used to optimize the comminution in SAG mills by controlling the milling parameters such as the mill speed, liner height and profile, feed size and ball size to achieve the efficient mill throughput.


AbstractIn the study an attempt was made to evaluate the relative efficacy of two important anti-gout agents, viz. allopurinol and febuxostat in the control of hyperuricemia/gout using poultry model. A 21 days' study was conducted on 48 VenCobb-400 broiler chicks randomly divided into four groups. In one group hyperuricemia/gout was induced by oral administration of diclofenac (group D), while in other two groups ameliorative effect of the two drugs under study was provided simultaneously i.e. diclofenac and allopurinol (group DA), diclofenac and febuxostat (group DF) and the fourth group was kept un-induced and untreated as control (group C). Both allopurinol and febuxostat inhibits xanthine oxidase enzymes, thereby reducing production of uric acid. The birds kept on diclofenac alone exhibited highest level of hyperuricemia, clinical signs of gout and overt adverse changes in the visceral organs, whereas, these changes were lesser in allopurinol and febuxostat treated groups. Further haematological, biochemical, patho-morphological and ultrastructural studies using transmission electron microscopy were carried out to evaluate the pathology and thus, ameliorative effect of allopurinol and febuxostat. The findings proved that allopurinol and febuxostat carries definite ameliorative potential as an anti-hyperuricemic and anti-gout potential in poultry, which was better expressed by febuxostat as compared to allopurinol.


Early warning is the activity of the mitigation phase concerned with monitoring precursors of a potential hazard to decide whether it is evolving to real risk and eventually initiate an early response. The first step consists of collecting updated and reliable data to support situational awareness from emergency operators. Data-centered Early Warning Systems (EWS) are focused on gathering data and run simulations to support decision-makers. A more sustainable approach consists of a people-centered EWS that takes profit from citizens who act as intelligent sensors collecting and sharing purposeful information. This people-centered approach can contribute to raising community awareness of the local environment and its vulnerabilities. In this paper, we introduce iWarn, a system relying upon mobile computing and gamification to integrate citizens in this process. The system has been developed following an action research approach to involve different stakeholders, including professionals, volunteers, and citizens.


For millions of Britons who lived through the war years from 1939 to 1945, poster themes such as "Dig on for Victory", "Careless talk costs lives", and "Is your journey really necessary?" were never to be forgotten. The wartime posters reproduced in this publication are a small selection from the many hundreds prepared by the Ministry of Information as part of their propaganda campaign. Although they were not intended to be great works of art, many were designed by distinguished artists of the day and their value goes beyond the topical. And as well as their message, they provide a glimpse of the prevailing manners and customs and mirror the changing fortunes of the war.

A novel Vivaldi antenna utilizing a tapered slot edge with a stepped structure (TSESS) to achieve miniaturization is presented in this paper. Compared with a conventional Vivaldi antenna of the same size, the proposed TSESS significantly extends the low-end bandwidth limitation and also improves the low-end antenna gain and radiation characteristics. The proposed antenna is fabricated and tested for validating the reliability of the design. The measured results show reasonable agreement with simulated ones. Moreover, a good time-domain response is indicated from the measured group delay, showing that the antenna meets the requirements of a UWB system.

We report the fast and efficient conversion of metal-organic frameworks (MOFs) to phase pure transition metal carbide (TMC) nanoparticles with uniform size using laser as the energy source, consuming only 6-Watt power. Nanoparticles of HfC, ZrC, TiC, V8C7, α-MoC, Cr3C2 and FeCx with homogeneous sizes (varied between 6 and 20 nm) were successfully produced, among which HfC and ZrC nanoparticles were obtained, for the first time, with sizes less than 10 nm and in pure phase. This method was operated directly in air, in stark contrast to traditional furnace heating and laser spray methods, where protective atmosphere are required. The use of MOFs allowed us to precisely tune the composition of TMC nanoparticles by dialing in the right type and desirable amounts of organic linkers. FeCx nanoparticles doped with various percentages of nitrogen atoms were synthesized for Fischer-Tropsch reaction without any pretreatment or activation. Extremely high iron time of yield (FTY) values were observed, 415 μmol gFe-1 s-1 and 550 μmol gFe-1 s-1 (with addition of K), in a 40h test without any decay in performance. High olefin to paraffin ratio was achieved for C2 to C11 products, where the ratio for C3 was higher than 10.
