Tall buildings with complex designs have been the recent trend in the field of architecture and structural engineering. For t his kind of buildings, wind flow analysis is equally important as structural analysis since wind loads are dominant for these types of structures. Computational simulation (URANS) turbulent models of Computational fluid dynamics are widely used to study the external flow behavior of a bluff body and its influence of shape factors. Nowadays a variety of problems are occurring because of tall buildings environment like down drought wind, vortices, downwind effects, etc. Wind comfort and safety on and around tall buildings have become important parameters for architects and town planners who need guidelines and simplified tools to take account of wind in their buildings. The objective of this study provides more insight on wind flow over tall buildings with different geometry. In order to evaluate the wind flow around the building in terms of upstream wind, downstream wind, recirculation zones are quantified in terms of width (D) and surface pressure measurements were employed to all geometries. Numerical analysis has been performed in FLUENT software with k-ω SST model as solver.Tall buildings with complex designs have been the recent trend in the field of architecture and structural engineering.

Semiconductor memories most specifically Static Random Access Memories (SRAMs) are becoming very popular in today's System-On-Chip (SOCs). Memories become more susceptible to faults when the complexity of these memories increase as the technology shrinks. In order to detect these faults, March algorithm has been widely used. This detection of faults in SRAM has been a time consuming process. Hence transient current testing (IDDT) methods are used. This paper implements a transient current testing method to detect faults in Complementary Mosfet (CMOS) SRAM cells. By monitoring a transient current pulse during a write operation or a read operation, faults can be detected. In order to detect the fault a Built in self test (BIST) circuit is developed. Simulations are carried out on a 6T SRAM circuit, to detect the difference in amplitude of the IDDT waveform. Simulations are also carried out on a 4 *4 SRAM array to detect the occurrence of fault .The SRAM circuit, array circuit and the sensor circuits are designed in I8Onm CMOS technology.

Purpose – The purpose of this paper is to identify and examine the major forces that are changing the way biopharmaceutical medications are purchased, distributed, and sold throughout the supply chain. This will become important as healthcare reform moves forward, and logistics will be transformed in this industry.Design/methodology/approach – Multiple interviews with key informants at each level of the value chain were combined with manifest text analysis from practitioner articles to derive key insights into the primary change drivers influencing the future of the biopharmaceutical supply chain.Findings – The research discovered radical shifts in the structure of the biopharmaceutical supply chain. Future research into biopharmaceutical supply chain practices will need to explore three primary issues: How will supply chain member compensation influence the power of parties within the network? How will the role of supply chain intermediaries change the landscape of medication delivery to the end customer...


Compared with commonly used deterministic methods,the stochastic hydrogeology method is a more rational resort for solving the flow and transport problems in the heterogeneous aquifers.On the assumption that the hydraulic conductivity field follows a lognormal distribution,the direct Fourier transform is introduced to generate multiple realizations of hydraulic conductivity field.Then the Monte Carlo method,based on the stochastic theory,is applied to investigate the effect of the spatial variation of hydraulic conductivity on the fate of contaminant plume.For the contaminant plume examined in this synthetic example study the spatial second moments defining the spread of the contaminant plume around its centroid increase with the enlargement of the variance of hydraulic conductivity distribution,while the first moment specifying the centroid of the plume is not influenced by the variance of hydraulic conductivity but dominated by the mean of hydraulic conductivity.Additional analysis demonstrates the sensitivity of both variance and coefficient of variation of plume concentration to the various variances of hydraulic conductivity field.

Holographic interferometry was used to determine the static deflection of grinding wheels. All limitations imposed on the experiment by the nature of the grinding wheel were overcome. The elastic movement of the structure of different grinding wheels was identified. The displacement was calculated for various wheels using the resultant fringe pattern.


We present a new DPSK receiver scheme where counter-propagating pulses collide in a saturated semiconductor optical amplifier, realizing photonically balanced single-ended detection. Decreased fluctuation of the mark level and 1.1-dB increased Q-factor is demonstrated experimentally at 22.3 Gbit/s.


The problem of radioactive waste has become a critical issue in the country and worldwide. The radioactive waste containers, containing different radioactive materials, have to be characterized before their final disposal. Destructive methods, although being the most precise, are also the most expensive and not the easiest ones from the radioprotection point of view. In this situation, high resolution gamma spectrometry proved to be a reliable method for the non destructive assay method. However, the non‐homogenous composition of the radioactive waste inside the drum makes the quantitative characterization of the radioactive waste drum a difficult task. Experimental studies and computed results, combined with Monte Carlo simulations using GESPECOR, are presented in this paper as a possibility to achieve this task.


In this paper we have undertaken an empirical analysis of the notion that firms introduce managerial innovations as a consequence of bad times, as in the "pit-stop" view of recessions. We first analyze a dynamic model of the firm and conclude that a competitive firm operating in a perfect capital market may well devote more of its employees' time to reorganization and other productivity improving activities during periods where the real output price or productivity is declining (e.g. recessions). We then investigate the hypothesis that a worsening of the firm's situation will lead to the introduction of productivity improving innovations of various kinds. Our individual company data tend to confirm this hypothesis with the single exception that firms tend to become more centralized when their real or financial position declines, despite the general view that it is decentralization which tends to improve the operation of a company in the long run.

ABSTRACT Lithology samples were collected from six sites of a petroleum hydrocarbon-contaminated site in northeast China along a contamination plume. The sulfate-reducing bacteria (SRB) diversity of all samples was analyzed by PCR-DGGE technology. The Shannon-Wiener indexes (1.004–3.665), Simpson indexes (0.516–0.907) and Pielou indexes (0.996–1.004) of all samples were used to characterize the abundances, advantages and evenness of the microbial communities. Additionally, Canoco for Windows 4.5 was utilized to analyze the correlation between dominant SRB and environmental factors. The results showed that the abundance, advantages and evenness of the sulfate-reducing bacterial community changed regularly along the contamination plume direction. The microbial homology of the samples was not high (0.25–0.80), and the dominant bacteria exhibited heteroplasmy. Additionally, the dominant bacteria were identified as uncultured bacteria. Canonical correspondence analysis (CCA) analysis showed that the distribution and structure of SRB communities were not obviously correlated with the concentration of total petroleum hydrocarbons (TPH), dissolved oxygen (DO) and other environmental factors. The results presented herein provide evidence of natural bioremediation in petroleum hydrocarbon-contaminated fields and information that will be useful to bioremediation of other contaminated fields.

Nanoparticles have acquired considerable attention from academia and industry due to their unique properties arising from the large surface area to volume ratio. A promising method to process these particles is fluidization. Furthermore, it is worth knowing that nanoparticles fluidize as clusters called agglomerates, formed by the relatively strong adhesion forces among the individual particles (1).


In this paper various schemes for solar photovoltaic water pumping are analyzed. Different aspects influence the performance of those systems; hydraulic load, battery efficiency, and variable speed operation are taken into account in order to suggest strategies for energy management and hardware implementation alternatives, under the restriction of operation in off-grid regions. Four pumping strategies, and their effect in the energy flow, are analyzed in this paper, using or not, batteries or variable speed.


Profiles of 2.8 MeV H+ microbeam extracted from a single tapered glass capillary optics were meas-ured by two methods for a future irradiation to an outer organ of insect target. The halo component was analyzed to be 575 μm in full width at half maximum (FWHM) at a plastic tracking detector CR-39 located 1 mm down-stream of the capillary. The core component was examined by knife-edge method according to the ion energies. The profiles consisting of more energy-loss events have wider FWHM, which can be reduced by Al thin layers.


A novel and mild synthesis method of carbaryl-( methyl-D3) was designed using α-naphthol as raw material.The intermediate 1-naphthyl N-methyl carbamate was prepared by α-naphthol and triphosgene under the NaOH as the catalyst. The target compound carbaryl-( methyl-D3) was obtained by condensation with methylamine-D3-hydrochloride. Synthesis route can avoid the use of highly toxic phosgene isocya-nate,and had the advantages of simple operation,short process,less byproduct. The yield of carbary-( methyl-D3)was more than 75% and deuterium labeled isotope abundance is not diluted. The product was confirmed by HPLC,IR,MS,1HNMR and13CNMR. The purity was more than 99. 5% and the deuterium enrichment was more than 99. 6%.


The outer membrane protein (OMP) prepared from Escherichia coli was found to be a potent mitogen for murine B cells and to be capable of inducing polyclonal antibody formation as well as a proliferative response. Spleen cells from nude mice responded equally as well to OMP as those from their normal litter-mates, whereas nylon-wool-purified T cells or thymocytes failed to respond. The proliferative response was dependent on the presence of macrophages. The macrophage dependency of the polyclonal antibody response seemed to be less than that of the proliferation. OMP was mitogenic for lipopolysaccharide (LPS)-resistant C3H/HeJ spleen cells, further indicating that OMP is an unique B-cell mitogen distinct from LPS.

OMP also enhanced the specific antibody response sixty-seven-fold to an optimal dose of sheep red blood cells (SRBC) in vitro. The kinetics of the response, however, was not altered from that of cultures without OMP. The anti-SRBC response of spleen cells from C3H/HeJ mice was also enhanced by the addition of OMP, suggesting that the adjuvant effects were not due to the LPS in the preparation. Antibody responses in vitro to TI-1 antigens, trinitrophenyl-LPS (Boivin) (TNP-LPSB) and TNP-Brucella abortus, were not enhanced in the presence of OMP. In contrast OMP enhanced the response to TI-2 antigens, TNP-LPSW (Westphal) and dinitrophenyl-Ficoll and T cells were shown to be required for these augmented antibody responses. Enhancement was not seen in nude mouse spleen cell cultures but was seen when nylon-wool-purified T cells were added to the cultures.


leak out when she was inebriated or in despair. Plath's Letters Home (1975), the letters to her mother, Aurelia Plath, proved impossible for Bishop to review and the attempt to do so quite literally made her ill. As Pollak comments with characteristic accuracy and aplomb, having indicated some of the psychological difficulty of Bishop's life: "We know that Bishop's tranquility effect on the poetic page was achieved at the cost of considerable self-suppression" (p. 219). Following the historical imperative that is deeply embedded in this book yields new material. For instance, Pollak may be the first critic to recognize how much there is to be gained by reading Bishop's review of Rebecca Patterson's The Riddle of Emily Dickinson (1951) alongside other contemporary reviews. Pollak's book is full of new and exciting research, things known but not put together before, and a respect for the direction that immersive detail may take. Though it is a book where Dickinson herself can begin to disappear under the projections, fears, and needs of others, there is a continual return to Dickinson's texts and the enduring puzzle of a writer who incites curiosity in others by turning away from them. Dickinson deserves our attention, and it remains part of her "paradoxical power" that her legacy for American women's poetry is so complex, multifaceted, and difficult to pin down (p. 265). As this fascinating study proves, this legacy deserves detailed attention and innovative research in its own right for what it can illumine about both poetry and the continuing dilemmas of sociability and selfhood.


The ecological environment of resources-exhausted cities was destructed seriously.Because of a large number of predatory,which led to some geological disasters,such as the collapse of mined-out,breaking out frequently.There are many obstacles in the establishment of ecological compensation mechanism,as the difficulties exist in the resource-exhausted cities.The National Development and Reform Commission in March 17,2008 established the first group of 12 resource-exhausted cities.Take this as an opportunity,we take the in-depth study the legal and policy issues,which related to the resources-exhausted cities in transition to build eco-compensation mechanism to build eco-compensation mechanism for resource-exhausted cities,and Put forward my initial ideas.


Soyabean allergy is one of the most common food allergies. The marked rise in allergenic reactions to soyabean is related to the increasing use of soya products in processed foods, which convert it in a major public health and soyabean industry concern. Different processes have been used to mask soyabean allergenicity, including heat treatment, fermentation, enzymic proteolysis, carbohydrate conjugation, genetic modification, extrusion and agronomic practices. It is still unclear which of the components of soyabean cause allergenic reactions. Some authors have identified 7S as a major soybean allergen; 7S is a N-glycoprotein that constitutes about 25% of the total soyabean proteins. Glycans forming glycoproteins have been described as being responsible for the allergenicity of some plants and insects and their removal has been proposed to reduce allergenicity. PNGase F is an enzyme used to deglycosylate different Nglycans such as those present in ribonuclease B, among others. No studies focused on deglycosylation of 7S by PNGase F activity for reducing its allergenicity have been found in the literature. The aim of the present research was to assess enzymic deglycosylation as a strategy for reducing soyabean protein allergenicity. 7S was isolated by isoelectric precipitation and the protein purity checked by SDS–PAGE. Enzymic deglycosylation was carried out on the isolated 7S (1 mg/ml) with PNGase F at pH 8 and 37 C for 24 h. Deglycosylation was followed by reversed-phase HPLC, SDS–PAGE and capillary zone electrophoresis analyses, which provided information relating to changes in protein structure. Antigenicity was assayed by immunoblotting and indirect ELISA with polyclonal rabbit anti-soyabean sera and horseradish peroxidase-labelled goat anti-rabbit IgG. The Figure shows SDS–PAGE (A) and immunoblotting (B), corresponding to the 7S control (c) and its deglycosylated form (d). As can be observed, the electrophoretic mobility of 7S changed as a result of deglycosylation, indicating a decrease in protein molecular mass. Immunoblotting and ELISA data suggest that the carbohydrate moiety forming 7S does not have a key role in its in vitro antigenic response as assayed in the present study. Further studies should be conducted in order to confirm the results by employing digestion and absorption assays in vitro and in vivo as well as an immunological test using serum from patients allergic to soyabean.


Sintering, coalescence, and compositional changes of hydrogen-terminated, crystalline silicon nanoparticles were examined as a function of temperature. Monodisperse aerosol particles ∼5 nm in diameter were synthesized by gas-to-particle conversion in a plasma reactor and then immediately heated as they flowed through a tube furnace. Particles were also collected as powders and then heated in other apparatuses. Structure and size changes were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), thermal behavior was characterized by differential scanning calorimetry (DSC), and silicon−hydrogen functionality changes were characterized by Fourier transform infrared spectroscopy (FTIR). At ∼500 °C, only silicon monohydride functional groups are observed in FTIR spectra. XRD results obtained after heating to that temperature indicate a small reduction in crystal size relative to the freshly generated particles, and TEM images show disorganized particle shells surrounding crystall...


Summary The follicular epithelium surrounding the vitellogenic oocytes of Locusta migratoria develops large spaces between the cells (becomes "patent") when the ovary is exposed in vitro to JH III or methoprene. In the presence of JH III, the optical path difference (OPD) of individual follicle cells in vitro, as measured by quantitative interference microscopy, increases markedly (i.e., the volume of the cell decreases). This response is inhibited by ouabain, indicating the involvement of Na+/K+ ATPase in the response. Methoprene also increases the OPD. JH II is less effective, while JH I and the bis-epoxide of JH III are without effect. Extracts of the abdominal neurosecretory organs of Rhodnius prolixus, a known source of an antigonadotropin which antagonizes the action of JH I on the follicle cells of Rhodnius, also antagonize the action of JH III on the follicle cells of locusts. Antigonadotropic activity was found in crude extracts of the thoracic ganglia of Locusta but was absent from other parts o...


In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, rst the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of adjacency matrix in acyclic digraphs are presented.


Ground-based rainfall observations during the pre-satellite era in the South West Pacific were examined for an extreme La Nina event that occurred in 1955-56. The rainfall observations were derived from the South Pacific Rainfall Atlas (SPRAT), a data compilation contributed by the regional meteorological services. The influence of tropical cyclone activity on both monthly and warm season rainfall anomalies were also accounted for using the International Best Tracks Archive for Climate Stewardship (IBTrACS) tropical cyclone database.


The literature suggests an association between drug use and addiction and the repertoire of social skills of the individual. However, there are still relatively few studies focusing specifically on the relationship between smoking and social skills. Moreover, Brazilian studies on the subject are scarce. This paper presents a review of the literature about smoking and social skills, emphasizing the theoretical underpinning research, as well as the main data obtained so far. One of the most investigated issues is the relationship between assertiveness and smoking. It is assumed that the lack of assertiveness and in particular the ability to refuse the supply of drugs and / or peer pressure to consumption can be a risk factor for smoking initiation, especially in adolescents. However, the literature on this issue is still controversial. It is assumed that further studies to elucidate these associations could contribute to prevention programs and intervention for tobacco use, using social skills training as a strategy.

The entomopathogenous fungus Verticillium lecanii (Zimm) Vieg (stump LBVl-2) and Beauveria bassiana (Balm) Vuilleman (stump LBBb-32) are broadly distributed and they have been evaluated under laboratory conditions against a great number of insect plagues as Anthonomus grandis Boheman, Bemisia spp. and Trialeurodes vaporariorum (Westwood), Schistocerca gregaria (Forskal), Plutella xylostella (Linnaeus) and aphids among other arthropods, that endorses their use in the control of plagues in the agriculture. The pathogenic action of those fungis was evaluated in mice and guinea pigs, providing them a conidium suspension of stumps in intraperitoneal applications and through the vagina. The possible pathogenic action of the fungal biopreparations from the above mentioned fungus was evalued, when they were given to mice through the nasal openings, with food and water and by contact, when the animals's body was sprinkled with the entomopathogenous solution. These last two trials were also valued on dogs and cattle. The applications on mice and cattle were carried out weekly during 6 months and were observed during 18 months, while the applications on dogs and cattle were done weekly, during the first two months and later every 30 d until turning two years. The animals subjected to treatments with V. lecanii and B. bassiana didn't show clinical alterations that could be registered by the veterinary; besides they didn't present either tissues or organ alterations or presence of the microorganisms studied. INTRODUCCION Los hongos entomopatógenos Verticillium lecanii (Zimmermann) Viegas, Beauveria bassiana (Balm) Vuilleman son inocuos al hombre y a otros vertebrados, ya que la temperatura de estos es superior a 35 oC y los mencionados microorganismos no pueden desarrollarse bajo estas condiciones. Este es uno de los indicadores que ha demostrado la inocuidad de estos entomopatógenos a animales de sangre caliente u homeotermos.1,2 Animales homeotermos fueron inoculados con esporas del hongo V. lecanii y pasados los 28 d, se les hicieron las pruebas anátomo-patológicas y microbiológicas, y no se detectó ninguna alteración, ni crecimiento del hongo en los cultivos de sus células.3 La patogenicidad de esos hongos entomopatógenos a artrópodos, su inocuidad a animales homeotermos y su posible combinación con plaguicidas químicos, hizo que en Cuba se desarrollaran trabajos encaminados al control de ectoparásitos en vacunos, motivo que ha hecho necesario hacer experimentos con la finalidad de verificar en las condiciones del ecosistema cubano la posible patogenicidad de los hongos entomopatógenos V. lecanii y B. bassiana a animales homeotermos. MATERIALES Y METODOS De la micoteca del Instituto de Investigaciones de Sanidad Vegetal Esperanza Rijo Camacho, Mercedes Luján, José R.

Revista CENIC Ciencias Biológicas, Vol. 33, No. 1, 2002. 34 de Cuba, se evaluó la patogenicidad de las cepas LBVl-2 y LBBb-32 de los hongos entomopatógenos V. lecanii y B. bassiana, respectivamente, a animales homeotermos. Para el desarrollo de este experimento se utilizaron 24 ratones y 24 curieles (para cada hongo), los cuales fueron distribuidos en seis grupos de cuatro animales cada uno por especie (un grupo era el testigo), ochenta perros de diferentes razas y edades (40 por biopreparado) y ocho vacunos adultos (cuatro por biopreparado). En la investigación se siguió la metodología que se emplea para el diagnóstico micológico en Veterinaria.4 Los biopreparados se obtuvieron por cultivo líquido estático para los hongos V. lecanii5,6 y B. bassiana.6,7 Cada uno fue administrado a los ratones y curieles a razón de 1 a 5 · 108 conidios/mL en el agua de beber, gotas nasales y en la comida. Esta última variante, así como las aplicaciones al cuerpo, se incluyeron en el experimento con los perros y vacunos. Cada biopreparado fue adicionado a la comida de los ratones y curieles, 30 y 60 mL, respectivamente. Igual procedimiento se siguió con el agua de beber, 60 y 120 mL para los ratones y curieles, de cada uno de los productos biológicos respectivamente; también los productos se aplicaron a través de las fosas nasales, una gota a los ratones y dos a los curieles. La aplicación intraperitoneal y a través de la vagina a los ratones y curieles se llevó a cabo con una suspensión de 5 · 108 conidios/mL de V. lecanii y otra de 4,3 · 108 conidios/mL de B. bassiana. Las cepas de los hongos antes mencionados fueron mantenidas en medio de papa dextrosa agar. La inoculación de conidios en las pruebas intraperitoneal fue de 1 y 3 mL a ratones y curieles, respectivamente. La introducción de la suspensión de conidios a través de la vagina fue de 10 mL a los ratones y 20 mL a los curieles. Los biopreparados y la suspensión de las cepas de ambos microorganismos, fueron suministrados a los ratones y curieles por períodos de cinco semanas, alternados con tres semanas de lavado. Este ciclo de tratamiento fue de seis meses y posteriormente, se mantuvo el análisis clínico durante 18 meses. Al terminar este, se sacrificó un animal por cada una de las diferentes variantes de hongo utilizado y se le realizó un examen anátomo-patológico y siembras de células de hígado, bazo, riñón y pulmón en medios de cultivo para bacterias y hongos. El resto de los animales de cada variante se mantuvo en observación para valorar la descendencia, desde el punto de vista etológico. La evaluación de los perros y vacunos se realizó con una frecuencia semanal los dos primeros meses y posteriormente, cada 30 d hasta los dos años bajo tratamiento y al igual que el resto de los animales ensayados fue sacrificado un ejemplar por cada tratamiento para las pruebas anátomo-patológicas y microbiológicas. Además, se consideraron 515 vacunos entre novillos y vacas que en condiciones de producción estuvieron sometidos a tratamientos con biopreparados fúngicos de B. bassiana y V. lecanii para el control de Boophilus microplus (Canestrini). RESULTADOS Y DISCUSION De los animales tratados con el biopreparado de V. lecanii cepa LBVl-2, sólo murieron dos ratones, uno de la variante que recibió el biopreparado en el agua y el otro de la variante en que se inoculó la suspensión de conidios del hongo por vía intraperitoneal. También murió un ratón del grupo testigo de esa prueba (Tabla 1). Los exámenes anátomo-patológicos realizados a los ratones muertos, no revelaron alteraciones visibles y en los análisis microbiológicos no se aislaron bacterias valorables. Las muestras sembradas para detectar hongos no arrojaron la presencia de V. lecanii y resultaron negativas para los tres ratones muertos. Los demás ejemplares de ratones, curieles, perros y vacunos sometidos a las diferentes pruebas con el hongo V. lecanii, no presentaron alteraciones y se mantuvieron dentro de los indicadores de salud para la especie. En los ensayos realizados con curieles tratados con el hongo B. bassiana, en la prueba de agua tratada murió un ejemplar, cuyo examen anátomo-patológico arrojó hepatomegalia con áreas de necrosis. En las siembras bacteriológicas, se obtuvieron aislamientos de Salmonella grupo B en el hígado y bazo y no se observó crecimiento del entomopatógeno suministrado (Tabla 2). Los ratones, perros, vacunos y los curieles sometidos a las diferentes pruebas con el hongo B. bassiana, no mostraron alteraciones que indicaran variaciones de los indicadores de salud de esas especies. No obstante, los perros y vacunos que fueron sometidos a tratamientos prolongados con los biopreparados fúngicos no presentaron modificaciones en su conducta y en los ejemplares sacrificados, no se observaron cambios anátomo-patológicos ni microbiológicos. Los animales de estos experimentos, así como otros vacunos que se encontraban en condiciones de producción y que fueron sometidos a tratamientos con biopreparados de V. lecanii y(o) B. bassiana para el Tabla 1.

A strong link exists between poverty and income, thus attainment of full employment by youths can reduce poverty, crimes, terrorism and prostitution. This study investigated the effect of NYSC/MDGs/WAP on the well- being of beneficiaries in Southwest, Nigeria. Simple random sampling technique was used to select 120 respondents (ex-corps members). Data were collected with a structured questionnaire and analysed using both descriptive (frequency and percentages) and inferential statistics (Chi-square and PPMC). The mean age of the respondents was 30.8 years, 67.5% were married with 3-5 family size, 73.3% were Christians and 73.3% were male. Those with B.Sc certificate were 46.7%, HND certificate 23.3%. Results indicate that 91.8% used the loan to start up a business, 89.2% engaged in agro-enterprises, with 35.8% into poultry production, 8.3% into beekeeping, while the remaining 10.8% diverted the loan into other businesses. Most of the respondents indicated training (89.2%) and self dependence (81.7%) as their benefits from the programme. Most severe constraint faced by respondents was inadequate credit facility/ loan. However, 55.8% of the respondents had favourable attitude and 53.3% had high well-being status. Marital status was significantly related to well-being of respondents (r=0.045, p=0.023). Attitude (r=0.554, p=0.000) of beneficiaries, benefit derived (r=0.284, p=0.002) and constraint encountered (r=-0.250, p=0.006) were significantly related to their well-being. Participants' involvement in NYSC/MDGs/WAP was beneficial and it has positive effect on their well-being. To ensure sustainability, availability of land, creation of marketing opportunities and follow-up becomes imperative. Keyword: Well-being, NYSC/MDGs/WAP, youth empowerment, agro-enterprise loan


On the one hand, some scholars pay more attention to the CSSCI, SCI and SSCI level than that of authoritative core journals; on the other hand, the current international academic circles have the awareness of non-English academic value, which is respected by a single domestic published papers and periodicals to pay attention to the country's practical application value in transition. Scientists in different countries have different knowledge background and the application demand, conduct most of the national scientific research projects, study the problem of domestic scientific resource environment and sustainable development.

Abstract Information Security has become a relevant subject in recent years, with greater awareness to the topic from major companies and general public. The frequent news regarding targeted attacks and large-scale information thefts resulting in major financial losses, sometimes even resulting in company bankruptcy, justify investments in protection mechanisms. At the heart of real-time security monitoring is the Security Information and Event Management system, commonly known as SIEM. These systems allow for security event collection and pattern discovery, by analyzing relationships between those events in …


Ability to record a sizable somatosensory evoked potential (SEP) in the absence of a recordable sensory nerve action potential (SNAP) suggests a normally occurring central nervous system amplifying process. Increments in SEP and SNAP amplitude with increasing stimulus strength between threshold and 2.5 times threshold (maximum) were compared. At threshold (40% of maximum stimulus) and 50% maximum stimulus, amplification measured 2.3 ± 0.7 and 2.0 ± 0.6, respectively. In 21 MS patients, the SEP at threshold stimulation was absent in 15, but normal in 5 of these at maximum stimulation. It is postulated that normal central amplification is markedly attenuated in MS, and this may be a sensitive indicator of early disease.

First are some thought-provoking views about changing demographics and global competition; second is information on skills needed in the twenty-first century workplace and the mindset of the current generation; and third is one California educational institution's approach to dealing with these changes to provide a well-trained biotechnology workforce to serve business and industry.


As we enter the twenty-first century, science and design have made incredible advances in the treatment and treatment of squanders associated with synthetic compounds and related items. With a beginning that began with attempting to follow government guidelines, the types of systems that have been designed to deal with various wastes have changed as more information has become available in the field. This can be attributed to interdisciplinary collaboration between various science and engineering disciplines and constructing fields While standard waste management procedures such as landfilling and ordinary wastewater treatment are still in use, the focus has shifted to reduce the amount of waste produced after treatment and to create an item from the waste gathered in some way. Numerous procedures such as ozonation, bright illumination, and other chemical treatments have gained popularity as a result of this.


We investigate the atomic-scale details of atomic force microscopy through a quasistatic molecular dynamics simulation together with a density-functional-based tight-binding method. The changes in the AFM tip shape, the size of the tip-sample contact area, as well as the microscopic hardness and Young's moduli of silicon ${111},{110},{100}$ surfaces are studied. Furthermore, the effects of hydrogen termination of the surface and of subsurface vacancies on hardness and Young's modulus are discussed.


MoTse's thought of thrift included saving on consumption and funerals,and pursuing no music.His ideas were the mainstream of traditional attitude toward consumption.This attitude contributes to correcting some unhealthy tendencies arising from the market economy,and establishing a new outlook on consumption in modern times.Opposing waste and advocating "rational thrift and rational consumption" is the features of the modern attitude toward consumption.

The first three years of study relating to Lake Agmon are reported in this issue of Wetlands Ecology & Management. We provide in this paper a general background on the Lake Hula Draining Project in the 1950s and the recent re-flooding and creation of the Agmon wetland.


The undesirable top notes or off-notes found in mint, clary sage, and cedarwood oils could be quantitatively determined using a non-equilibrated solid phase microextraction/gas chromatography/selected ion monitoring/mass spectrometry (SPME/GC/SIM-MS) technique. Using the low threshold components, dimethyl sulfide, 2-methylpropanal, 2-methylbutanal, and 3-methylbutanal, which are associated with the off-notes of these oils, their levels could be reproducibly quantitatively determined. The highest level of off-notes was found in a sample of Scotch spearmint oil where the levels of the four constituents were, dimethyl sulfide (238 µg g−1), 2-methylpropanal (286 µg g−1), 2-methylbutanal (1048 µg g−1) and 3-methylbutanal (1489 µg g−1). These quantitative results in combination with sensory evaluations could provide for a powerful overall assessment of essential oil quality. Copyright © 2004 Society of Chemical Industry

Two sets of more than 850 days of mooring records and satellite altimeter data are used to explore the features and spatiotemporal evolution of near-inertial waves (NIWs) near Nansha Island in the southern South China Sea (SCS). The observed NIWs are dominated by clockwise (downward energy propagation) motions and show a clear blue shift with a distinct peak frequency of 1.09 f during two large NIW events. The near-inertial kinetic energy (NIKE) is primarily concentrated in the upper layer and radiated downward. The largest value of depth-integrated NIKE reaches 3.5 KJ/m2. Besides, the NIWs are dominated by the first three modes, which account for 80% of the total NIKE. Moreover, the depth-integrated NIKE exhibits an apparent seasonal variation, with the largest NIKE in winter, which is almost three times larger than that in other seasons. Every large NIKE event is attributed to the passage of storms and is dominated by mode-2 NIWs. The dominance of the mode-2 NIWs is likely caused by the interaction between NIWs and mesoscale eddies.

This paper reports on the validation of ENVISAT Advanced Along Track Scanning Radiometer (AATSR) observations in the English Channel and Bay of Biscay during 2004-2005. A commercial ferry operating between Portsmouth, United Kingdom and Bilbao, Spain has been fully instrumented with oceanographic and meteorological instrumentation for the purpose of AATSR validation. The instrument package includes an Infrared Sea Surface Temperature Autonomous Radiometer (ISAR), three axis sonic anemometer, long-wave and short-wave radiation sensors, humidity and surface pressures sensors, thermosalinograph, hull-mounted thermistor and irregular continuous plankton recorder (CPR) tows. All in situ instrumentation is calibrated regularly to maintain high accuracy. These data have been analysed to validate the skin sea surface temperature (SSTskin) observations reported by the AATSR. In situ observations nearly contemporaneous with ENVISAT AATSR data have been matched together using an automated system that adheres to strict match-up rules. We find that AATSR dual view SST retrievals have a warm bias of 0.2K ±0.33K in March December 2004. However from December 2004-September 2005 the AATSR dual view SST retrievals are practically unbiased (0.065K) with more variability in the summer seasons (March-June 2005: ±0.12K, June-September 2005: ±0.39K). In contrast, the nadir only SST retrievals have a relatively constant warm bias throughout the study period of 0.5K ±0.38K. An assessment of typical errors associated with the end-to-end validation process is presented. Using in situ observations and data from the Met Office Shelf Seas operational model system, we provide an error budget for the ISAR-AATSR validation data set. The largest errors in the validation process are attributed to strong horizontal and vertical temperature gradients in the upper ocean during low wind speed clear sky conditions. These errors can be minimised by choosing ocean areas that are well mixed and wind speed conditions > 6 m/s. We recommend that all satellite SST validation data should be assessed in this way to minimise unnecessary uncertainties in the validation process.


This is the protocol for a review and there is no abstract. The objectives are as follows: To determine whether NAVA compared to other forms of triggered ventilation results in reduced rates of BPD or death in newborn infants, either used as a primary or rescue mode of ventilation. To assess the safety of NAVA by determining if there is a greater risk of episodes of hypocarbia or hypercarbia, intraventricular haemorrhage, periventricular leukomalacia, or air leaks compared to other forms of triggered ventilation. Secondary objectives will be to determine whether any benefits differ by gestational age (term or preterm). In crossover trials, outcomes include peak pressure requirements, oxygenation index and the work of breathing.


In order to study the location of hydrogen atoms and the effects of their insertion into R2Fe17, spin–echo NMR experiments have been carried out on the hexagonal Y2Fe17H x (x=0, 3.0, 4.7), rhombohedral Sm2Fe17H x (x=0, 1.7, 5.7), and mixed‐phase Gd2Fe17H x (x=0, 2.3, 5.8) compounds. 1H and 89Y spectra obtained from Y2Fe17H x clearly demonstrate that the hydrogenation process is reversible upon vacuum annealing. For both Y2Fe17H x and Sm2Fe17H x , the 1H spectra show two broad peaks; the peaks are tentatively assigned to H atoms in the tetrahedral and octahedral interstitial sites, and a hydrogen filling scheme is proposed. For Gd2Fe17H x , a single broad 1H peak near 70 MHz is observed; application of an external magnetic field indicates that the hyperfine field has the same direction as the net magnetization.


India, 1943: In a regimental hill station, the ladies of Pankot struggle to preserve the genteel facade of British society amid the debris of a vanishing empire and World War II. A retired missionary, Barbara Batchelor, bears witness to the connections between many human dramas; the love between Daphne Manner and Hari Kumar; the desperate grief an old teacher feels for an India she cannot rescue; and the cruelty of Captain Ronald Merrick, Susan Layton's future husband."


The Odyssey spacecraft documented the existence of heterogeneously distributed hydrogen at martian mid-latitudes, suggesting that large areas of the near-equatorial highlands contain near-surface deposits of 'chemically and/or physically bound H20 and/or OH' in amounts up to 3 .8% equivalent H20. Shallow occurrences of water ice are not stable near the martian equator, making the hydrogen deposits at these latitudes somewhat enigmatic. Clay minerals and zeolites have both been proposed as possible water-bearing constituents on Mars, and both are common terrestrial alteration products of hydrovolcanic basaltic ashes and palagonitic material comparable to those that may be widespread on Mars. Smectites within martian meteorites, attributed to hydrous alteration on Mars rather than on Earth, provide direct evidence of clay minerals from Mars. In addition, new thermal emission spectrometer (TES) data provide good evidence for unspecified zeolites in martian surface dust [6] . The nature of the hydrogen-containing material observed in the equatorial martian regolith is of particular importance to the question of whether hydrous minerals have formed in the past on Mars. Also, whether these minerals exist in a hydrated (i .e., containing H2O molecules in their structures) or dehydrated state is a crucial question . The existence of hydrous minerals ismore » also important in connection with their possible role in affecting the diurnal variation of the martian atmosphere, in their potential role in unraveling the paleohydrology and paleobiology of Mars, and in their possible use as a water resource to support exploration of the martian mid-latitudes.« less


According to the convergence and diversity of particle swarm optimization,this paper proposes a chaos concussion particle swarm optimization algorithm(CCPSOA) which uses the properties of chaos and concussion link to lead particles' exploration,so as to equip the swarm system with an ability of sustainable search. Numerical simulation demonstrates that not only can the proposed algorithm keep the population diversity,but also effectively prevent the premature convergence phenomenon.


In this review,simply basic concepts about chirality,chirotechnology and biocatalysis were introduced Chirality means that one organic molecule possesses dissymmetry and thus forms two enantiomers with different stereo structures Chirotechnology refers to the preparation of chiral compounds by some means mainly including chiral source, racemic resolution, asymmetric synthesis and so on Biocatalysis means that enzymes or microbes are utilized to catalyze chemical reactions, and it is a key technology to produce chiral compounds This paper also introduced some practical examples producing chiral compounds by racemic resulution or dissymmetry synthesis


The kilogram is the last unit of the international system (SI) still based on a material artifact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long term relative drift between the IPK and a set of copies kept under similar conditions. Since the long term stability is one of the major conditions set on the SI base units, this situation is no longer satisfactory and a new definition of the mass unit becomes a priority for the metrology community. A promising route towards a new definition based on fundamental constants is given by the watt balance experiment which links the mass unit to the Plank constant h. Today, the kilogram is the last unit of the International System of Units (SI) still based on an artifact, the international prototype of the kilogram (IPK), kept at the Bureau International des Poids et Mesures (BIPM). The IPK prototype that has been machined in 1878, is a cylinder of platinum-iridium alloy (Pt 90% - Ir 10% in mass) whose height (39 mm) is equal to its diameter. Six copies were designated as official copies and are kept in the same conditions as the international prototype. At that time, about seventeen other copies were given to the member states of the meter convention to materialize their national prototype. Since then, other countries have joined the meter convention and new national prototypes have been machined and added to the existing set of international prototype copies. To survey the evolution of the different copies relative to IPK three comparisons have been organized since 1880. The results of these comparisons have clearly put in evidence, a relative drift of this set of masses with respect to IPK. The mean drift of the official copies has been evaluated to 0.5 µg/year. Nevertheless, it is clear that the actual definition of mass does not allow attributing the drift to IPK or to the copies. Moreover, variations of the mass unit directly reflect on the ampere definition and therefore on the whole set of electri- cal units. Since it is now possible to compare two mass standards made out of the same material with an uncertainty of about 1 µg, the instability among the international mass prototypes - including IPK - is a major contribution to the final uncertainty. Clearly, such a situation is no longer satisfactory for one of the base units of the SI. There is now a general consensus in the metrology community that the time for a redefinition of the kilogram has come. To get a better stability, the new definition should be linked to a physical fundamental constant with a relative uncertainty in the order of 10 -8 . During the last decades, several


Magnetic skyrmions have been the focus of intense research with promising applications in memory, logic and interconnect technology. Several schemes have been recently proposed and demonstrated to nucleate skyrmions. However, they either result in an uncontrolled skyrmion bubble production or are mostly targeted towards integration with racetrack memory device. In this work, we propose a novel scheme for a controlled single skyrmion nucleation in a confined nanowire geometry with sub-100 nm width using a generalized approach of "localized spin current injection" technique in material systems exhibiting low Dzyaloshinskii-Moriya interaction (DMI). Our proposed nucleation mechanism follows a pathway involving the creation of a reversed magnetic domain containing one or more pairs of vertical Bloch lines (VBLs) that form an edge-to-edge domain wall as the VBLs get annihilated at the edge of the nanowire. However, pinning of the edge domain walls within a narrow gap using notches or anti-notches results in the creation of a magnetic bubble with defect-free domain wall that eventually relaxes into a circular skyrmion structure. Our simulations predict that the proposed mechanism allows skyrmion nucleation on sub-nanosecond timescale, shows robustness to variations like local pinning sites and is applicable for any skyrmion-based logic, memory and interconnect application.


Proliferative activity of the aortic intima cells in the course of experimental rabbit hypercholesterolemia is studied. The most intensive DNA synthesis was found in macrophages and smooth cells transforming into the foam cells as shown by electron-microscopic radioautographic analysis. DNA synthesis by damaged and dying foam cells is shown. Cytophotometric analysis showed the small proportion of foam cells in the atherosclerotic lesions to be polyploid.


This research aims to describe students' behavior in using the internet while learning and analyze factors that change the students' behavior at the State Senior High School 2 of Sungai Ambawang. The research used a qualitative method to obtain a detailed and comprehensive understanding of their behavior using the internet as learning media at school. The research found that the student struggled to concentrate during the lesson. One of the factors was that the students played game, browsed other media, and did other online activities. The data were collected using interviews, observation, and documentation. To analyze the data, the researchers did several procedures such as data reduction, presentation, and verification. This research used a behaviorism theory expressed by B.F. Skinner. This theory focuses on the relationship between the effect of an individual's behavior on his surroundings and the effect of the surrounding on the individual. According to Skinner, almost all human behavior falls into two categories: respondent and operant behavior. Respondent behavior is an unconscious action (reflex) that is resulted from a particular stimulus from the surrounding. Meanwhile, the operant behavior refers to behavior emitted spontaneously and freely.

The use of sports sponsorship as a marketing tool is in the rise. Estimates indicate that the values invested in this activity have grown over one thousand per cent in the last twenty years, reaching the total sum of approximately US$ 21 billion in 2004 and around US$ 111 billion by 2009. Despite the fact that the capital needed to conduct a sponsorship program is growing considerably, companies that invest in this kind of marketing activity are often not able to obtain the expected return. The main objective of this study is to assess sports sponsorship effectiveness on consumers. In order to achieve this objective, the Brazilian National Soccer Team and its three official sponsors, Nike, Vivo and Guarana Antarctica, were chosen as a case-study. The effectiveness of the sponsorship was evaluated using the test of recall, a widely accepted criterion adopted by companies that measure sponsorship return. Two different models were used to measure the sponsorship effectiveness. The methodology employed both an exploratory and a descriptive study via a survey with 382 individuals. Three different methods of statistical analysis were used to examine the data: Factor Analysis, Multiple Regression and Logistic Regression. Based on the results it is possible to show that some factors have more influence on recall than others: interest that individuals have for football and the frequency with which they watch sports events on television. On the other hand, factors like the emotional involvement with the Brazilian National Football Team, and the exposure to its matches do not influence significantly the recall of the sponsors. Finally, perceived similarity between the sponsors and the team also influence their recall.

The era of COVID-19 has profoundly shaken the foundations of our lives. Our event venues have closed; the support systems that we depend on for delivering works of art have all been shuttered. In response, musicians have turned to the digital world. While the digital world has become an important collaborative interface, I believe it is imperative to also explore the opposite direction—and take it outside! Even pre-COVID-19, it has been important to expand musical methodologies by connecting music creation systems with environmental sound practices in new ways. As recent developments in technology have opened up the possibilities of new types of environmentally based artistic engagement, artists of all kinds increasingly feel a profound need to participate in climate crisis activism through creative work.


INTRODUCTION
Renal transplant recipients are at increased risk of keratinocyte skin cancers with a tendency to have multiple, aggressive and difficult to treat tumours. The eye and the skin share the same embryological ectoderm. Iris pattern has recently been reported as a predictive risk factor for skin cancer in non-immunosuppressed Southern European1 and Irish populations2 .

AIMS
To analyse if an individual's iris pattern is an independent risk factor for the development of keratinocyte skin cancers in renal transplant recipients.

METHODS
Iris patterns of 110 renal transplant recipients were evaluated using the Simionescu visual 3-step technique (Iris periphery, colarette and iris freckling3 ). Established risk factors for skin cancer in transplant patients were recorded as confounding factors.

RESULTS
Observational cross-sectional study including 110 renal transplant population. Thirty-one participants had skin cancer. In the skin cancer group, iris periphery was blue/grey in 74.3% (p = 0.053, OR 2.5), the colarette was light brown in 57.1% (P < 0.0043) and iris freckles were present in 55%(P=0.044). Dark brown and blue colarettes were observed in controls. Binary Logistic Regression analysis showed light brown colarette is a significant independent risk factor for skin cancer (OR 4.54, P 0.02, CI 1.56-10.57).

CONCLUSION
Within this renal transplant population a blue iris periphery, light brown colarette and presence of freckling confers an independent risk for keratinocyte skin cancer. Iris pattern is a useful tool for identification of transplant patients at risk of keratinocyte skin cancer and an easy-to-use technique for risk evaluation in this cohort. This is the first study looking at iris pattern and keratinocyte skin cancer risk in renal transplant population.


ABSTRAK
ABSTRACT
In order to obtain maximum results in a farming system, especially farming in rainfed areas, where both planting and harvesting  failure often occur, the determination or selection of crop and cropping patterns becomes important. Likewise, combining different types of crop and livestock farming in a particular farming pattern is an effort in order to increase the farmer's total income.This study aims to: (1) Identify the farming pattern or mixed farm applied by rainfed farmers; (2) Calculating the income of each farming pattern; (3) Optimalizing the rainfed farming in Rembitan Village, Pujut Sub-district. This research uses descriptive method. The analysis used are: income analysis, linear programming, and sensitivity analysis.The results showed that: (1) There are 10 farming patterns conducted by farmers in the rainfed areas of Rembitan Village, Pujut Sub-district, Central Lombok Regency; (2) The average total farming pattern income in the rainfed areas of Rembitan Village, Pujut Sub-district, Central Lombok Regency, which combines crop and livestock farming is Rp 12.263.596,00/year; (3) There are three recommended farming petterns activity in rainfed areas of 882 ha maximizing Rembitan Village revenue of Pujut Sub-district, Central Lombok Regency, Rp 20,649,455,129 per year with distribution, namely: X4 activity of 177,71 hectares (20,15 %); X7 of 145,633 hectares (16,51%); and X10 of 558,657 hectares (63,34%).


According to the actual conditions of Haokou hydropower station,a three-dimensional finite element model was developed for the typical non-overflow section of Haokou concrete gravity dam.Based on the static field of the dam,the dynamic analysis results obtained from the response spectrum method were superimposed with the static analysis results determined by the normal storage of the dam,which provided the dam stress under the static and dynamic forces.The strength and ability against sliding of the dam were analyzed and evaluated using the rigid body limit equilibrium theory.The results demonstrated that the strength of the dam meets the standard requirement under the design earthquake action.The safety factor against sliding the dam foundation was 4.4,which was greater than the minimum safety factor allowed by the standard,and therefore the dam is safe.


Large (> 100 mm$^3$), relatively pure (type II) and low birefringence single crystal diamond can be produced by high pressure high temperature (HPHT) synthesis. In this study we examine a HPHT sample of good crystalline perfection, containing less than 1 ppb (part per billion carbon atoms) of boron impurity atoms in the {001} growth sector and only tens of ppb of nitrogen impurity atoms. It is shown that the boundaries between {111} and {113} growth sectors are decorated by negatively charged nitrogen vacancy centres (NV$^-$): no decoration is observed at any other type of growth sector interface. This decoration can be used to calculated the relative {111} and {113} growth rates. The bulk (001) sector contains concentrations of luminescent point defects (excited with 488 and 532 nm wavelengths) below 10$^{11}$ cm$^{-3}$ (10$^{-3}$ ppb). We observe the negatively charged silicon-vacancy (SiV$^-$) defect in the bulk {111} sectors along with a zero phonon line emission associated with a nickel defect at 884 nm (1.40 eV). No preferential orientation is seen for either NV$^-$ or SiV$^-$ defects, but the nickel related defect is oriented with its trigonal axis along the sector growth direction. Since the NV$^-$ defect is expected to readily re-orientate at HPHT diamond growth temperatures, no preferential orientation is expected for this defect but the lack of preferential orientation of SiV$^-$ in {111} sectors is not explained.


The aircraft industry demands a significant increase in terms of efficiency and gravimetric power density of power converters for next generation aerospace applications. Between the two minimum targets, i.e. an efficiency > 98% and a gravimetric power density > 10 kW/kg, the specification concerning the converter weight is the most challenging to fulfill. Since cooling systems and magnetic components dominate the weight breakdown of conventional converter concepts, multi-cell topologies, enabling improved semiconductors performance and reduced filtering requirements, are foreseen as promising solutions for the power electronics on board of More Electric Aircraft. On the other hand, the necessary simultaneous operation of a high number of cells inevitably limits the reliability of multi-cell converters if redundancy is not provided. In this paper, a favorable scaling trend of power density with respect to reliability, aiming to guarantee fault-tolerant operation without affecting the performance figures, is identified in modular multi-cell converters. Thus, a 45 kW weight-optimized modular multi-cell three-phase inverter featuring a redundant power stage is optimized, achieving an efficiency of 99% and a gravimetric power density of 22.8 kW/kg.

A VOD server has to employ admission control algorithms to decide whether a new client (request) can be admitted without violating the requirements of clients who are already being serviced. This paper presents and analyzes four specific admission control algorithms pertaining to the deterministic and predictive category. These algorithms are: maximum, adaptive maximum, average and adaptive average. They are studied in detail for CPU and network resources. The adaptive algorithms are our own contribution and we show that they use an exponential weighted average to guess the future resource needs of a stream, rather than just using the maximum or mean over the whole period. Thus, they provide smoothing and so a closer matching of resources used to those reserved and so higher capacity and less waiting time.


The ability to express confinement properties of objects is crucial in the context of component-oriented software development. Recently, several techniques based on type systems have been developed to express and check confinement properties for objectoriented programs. Unfortunately, learning these often quite complex type systems is a burden to programmers. Furthermore, without inference techniques, they require nontrivial code annotations. In this paper, we propose a very lightweight approach to add encapsulation support to a Java-like language. We annotate class declarations and new statements to express which classes instantiate new components and which objects are confined to their surrounding component. To check encapsulation we developed a modular static analysis based on an abstract interpretation of single components. Successfully analyzed components will never break confinement regardless of the program they are used in.


Several novel betulin derivates were prepared using Mannich reactions as a key step. Starting from 3‐ethynyl‐3‐hydroxy‐lup‐20(29)‐ene derivatives, copper‐catalyzed Mannich reactions yielded hydroxypropargyl ammonium hydrochlorides or their corresponding methiodides. All compounds were screened in a sulforhodamine B assay for their antitumor activity using a panel of 9 human cancer cell lines. Some of these compounds showed significant cytotoxicity; they act by triggering apoptotic cell death as shown by additional acridine orange/propidium iodide assays, Trypan blue tests, DNA laddering experiments, and investigations of the cell cycle.


Metal magnetic memory technology was an important method for detecting the steel-cord conveyor belt early fault, characteristics of magnetic memory signal extraction is critical for judging of the conveyor belt failure. Generally using of magnetic memory signal maximum gradient value can quickly judge the stress concentration zone, but the magnetic memory signal is susceptible to effected by environmental and noise; In view of the weak and non-stationary characteristics of magnetic memory signal, this paper has proposed the singularity detection method based on wavelet transform modulus maximum for metal magnetic memory signal, the method could exactly judged the stress concentration zone of joints and located the fault points of the steel-cord belt, the characteristic gradient of magnetic memory signal and the Lipschitz exponent were extracted. The result of simulation indicated the technology was effectively for judging the stress concentration zone and fault point. DOI: http://dx.doi.org/10.11591/telkomnika.v11i9.2866

Due to the ever growing and more complex demands on the properties of polymer materials, raw material producers and plastic processing industries are more and more interested in the continuous synthesis and modification of polymers. In this article the production of polystyrene and styrene–isoprene copolymers by anionic s-butylithium initiated bulk polymerization in a co-rotating close intermeshing twin screw extruder is described. In spite of high reaction temperatures of above 200°C the polystyrene stays "living," which makes it possible to modify it in the melt by adding more monomers. The following processing methods were developed and analyzed: (1) homopolymerization of styrene; (2) copolymerization of styrene–isoprene monomer mixtures; (3) sequential polymerization of styrene and isoprene. The polymerized material resulting from the above-mentioned processes differed considerably in structural features and final properties depending on the process parameters. As for homopolymerization of styrene, the influence of the process parameters screw rotation speed and screw geometry on the range of molecular weight distribution was investigated. Products made according to the two copolymerization methods were analyzed with regard to their structure and mechanical properties. The tests revealed that for sequential copolymerization the temperature in the polymerization zone has a decisive influence on the product quality. The influence of the screw rotation speed is less important. © 1993 John Wiley & Sons, Inc.


ABSTRACT Why did Mexico's disruptive indigenous movement begin to fade during the 'indigenous boom' years of the 1990s? Containing the influence of the Zapatista Army of National Liberation (EZLN) in Oaxaca, a state with a large indigenous population and a long history of radicalism, had much to do with it. This article suggests that neoliberal multicultural reforms created a new formula for distinguishing an 'indio permitido' from its unauthorized Other and helped sideline one of the state's most powerful indigenous coalitions, the Popular Indigenous Council of Oaxaca – Ricardo Flores Magón. By examining the cultural politics of Mexican divide-and-conquer strategies in a moment of insurgency, this article highlights how a tradition-and-transition mode of neoliberal governance emerged in Oaxaca in the 1990s. It divided and isolated a 'participating' indigenous subject from a protesting one, and played a key role in preventing the further consolidation of indigenous movements in southern Mexico.

This study was undertaken to examine the effectiveness of integrating movie clips in the teaching and learning of English grammar in an industrial training institute. The study was designed to investigate whether integrating movie clips in English grammar lesson will affect students' performance in grammar. It also examined students' feedback towards learning English Grammar through integrating movie clips in their grammar lesson. The study was conducted within a period of six weeks where respondents were divided into two groups namely the experimental group and control group. Three types of activities were carried out during the treatment period for three week continuously on the experimental group. On the other hand, the control group was exposed to the same grammatical item using the traditional method. The differences in students' performance were tested using Pretest and Post-test. Students' feedback on learning grammar through movie clips was gathered using questionnaires. Results gathered showed that teaching of grammar using movie clips has the most significant improvement compared to the traditional method. Feedbacks from the questionnaires also showed that almost all students gave positive remarks on the teaching of English grammar through movie clips.

Ball-sealer diversion has been proven to be an effective and economical way to increase fractures and fracturing volume in multistage hydraulic fracturing and matrix acidizing treatments. However, designing and implementing a successful ball-sealer diversion treatment is still challenging. Typically, operators rely on empirical data to determine diversion parameters and need an understanding of accurate ball transport and diversion behaviors. A model for optimizing operating parameters, including fluid and ball properties, and predicting the diversion performance of ball sealers before treatment is needed for designing the fracturing process.
 In this work, we systematically investigated ball-sealer diversion using experimental and numerical methods. The resolved model of computational fluid dynamics (CFD) and discrete element method (DEM) is first developed to simulate the transport of a large ball in a horizontal wellbore with side holes. The experimental results validated the numerical model. The effects of the ball position in the pipe, flow ratio of the hole to pipe, injection flow rate, and ball density on the diversion performance were studied under field parameters.
 The results show that the ball sealer easily misses the heel-side perforation due to the inertial effect and travels to the toe side due to the large inertia and turbulent flow. The ball position and flow rate ratio are crucial for the diversion performance. There is a threshold value of the ball position under the specific condition, and the ball successfully turns to the perforation only when the threshold distance is met. A ball sealer closer to the perforation will have a larger probability of blocking the hole than the ball at the other side of the wellbore. The larger the flow rate ratio, the more the drag force on the ball, and the ball can successfully divert to the perforation despite the ball being far from the hole. The injection flow rate and ball density negatively correlate with the diversion performance due to the large inertia and gravity. The best classification result with the F1 score of 87.0% in the prediction set was achieved using the random forest (RF) algorithm. It provides new insight into developing ball sealers and adjusting fracturing parameters based on machine learning (ML) methods.


6084 Background: The main purpose of the present study was to find predictive biomarkers that can be routinely used for the response to chemotherapy in head and neck squamous cell carcinomas. From this standpoint, we have investigated the gene expression profile of individual tumors as available predictive biomarkers.

METHODS
Sixty-four tumor specimens from patients undergoing radical treatment for squamous cell carcinomas of the oro- and hypopharynx in stage II, III, or IV, were included in the present study. There were 30 primary tumors sites in the oropharynx and 34 in the hypopharynx, respectively. All patients were administered induction chemotherapy (FP) with a combination of 5-FU (800 (600) mg/m2 d1-5 (6)) and cisplatin (80 mg/m2 d6 (7)) before definitive therapy. This chemotherapy was used in order to select patients for organ preservation based on the response and decrease in late salvage surgery rate. Treatment was repeated every 3 to 4 weeks. Using biopsy specimens, we analyzed their gene expression profiles with the following 25 markers, which we thought were likely predictors of the response to anti-cancer agents: TS, DPD, OPRT, TP, COX2, MDR1, MRP1, VEGF, EGFR, HER2, PIK3CA, PTEN, p53, Rb1, Bcl2, BclX, BAX, GSTπ, ERCC1, XPA, E2F1, ENT1, Rev3, β-tubulin, and Survivin. These mRNA expressions were quantified by real-time reverse transcription polymerase chain reaction (real-time RT-PCR) assay. Clinical markers, such as T and N factor, gender and age were added, and logistic regression analysis and likelihood ratio test were conducted.

RESULTS
Univariately, response for chemotherapy was significantly correlated with T factor (p = 0.015), and the mRNA expression level of XPA (p = 0.018) and OPRT (p = 0.047). Meanwhile, using a multivariate logistic regression analysis with these factors (clinical markers, OPRT and XPA), T factor (p = 0.048) and the expression of XPA (p = 0.035) were demonstrated to be independent predictors for chemotherapy.

CONCLUSIONS
XPA (Xeroderma Pigmentosum A) and OPRT (Orotate phosphoribosyl transferase) may be possible reliable predictive biomarkers for FP therapy, and might help the decision-making strategy for individual patients with head and neck cancers. No significant financial relationships to disclose.


RADIOLOGICAL and clinical evidence of largebowel obstruction in pancreatitis has been infrequently reported in the literature. Narrowing at the splenic flexure, accompanied by distension of both the large and small bowel, was described in 1957. 1 Glenn and Baylin 2 noted spasm in the midtransverse colon among other x-ray features of acute pancreatitis. Australian authors 3,4 have used the term "colon cut-off sign" to describe the finding of gas in the ascending colon up to the hepatic flexure, with absence of gas in the transverse colon. The following case is one in which survey films of the abdomen, repeated barium examinations of the colon, and serum amylase determinations illustrate a temporary obstruction near the hepatic flexure, due to an acute attack of pancreatitis. The lesion at one point was thought to so resemble carcinoma that operation was planned, but fortunately never executed. Report of a Case A 26-year-old white

In Ecuador, national epidemiological surveys have not been updated; however, some regional studies in the northern areas of the country still report a high prevalence of dental caries. The aim of this study was to determine the experience, severity, and need for treatment of dental caries in school children aged 6 to 12 years in urban and rural settings in three provinces of southern Ecuador. This cross-sectional, relational study examined 1938 schoolchildren in the provinces of Azuay, Cañar, and Morona Santiago. The survey instruments were based mainly on the WHO manual Methods of Oral Health Surveys (dmft) for primary and permanent dentition (DMFT), as well as the prevalence, severity, and Significant Caries Index (SCI). The parametric Student's t-test was used to compare two groups, and the Spearman's Rho and Tau-c Kendall correlation coefficients were used to associate the categorical variables. Results: The prevalence of caries in the primary dentition was 78% and 89.2% in the permanent dentition. The dmft (M = 4.12, SD = 2.86) and DMFT (M = 3.62: SD = 3.07) placed the general group in a moderate caries index. The need for treatment was 90.68% in the primary dentition, while it was 87.99% in the permanent dentition. Caries severity in both dentitions was high (M = 7.74; SD = 3.42). Conclusions. Alarming indicators of caries experience and the need for treatment were observed in the population studied.


Peter F Knight was born in Kensington. He went to Merchant Taylors' School in Northwood (White House) from 1944 to 1949 and then to Westminster Medical School. While at school he developed his sporting interests, which were to continue for most of his life. At school he achieved victor ludorum three years in succession. At medical school he fitted in both rugby and sailing.

A general practitioner friend of his father's who had a link to Sir Ivan Magill introduced him to the world of anaesthetics while he was still a medical student. By the time Peter qualified, he had already assisted with some 400 procedures requiring anaesthesia.

This huge experience would have stood him in good stead when, soon after qualification and starting his national service, he found himself in Malta and Benghazi, where he was the sole anaesthetist, learning to cope, as many had to do, with a book in one hand and the patient …


DBpedia is a triple-based binary-relational database which contains 3 billion, and counting, facts derived from Wikipedia. Ideally, individuals should be able to access semantic web triple-store data through natural-language queries. Several attempts have been made to create natural-language (NL) query interfaces to DBpedia. However, no one has yet built a wide-coverage natural-language query processor for DBpedia. DBpedia does not currently encode contextual data representing the time, location or other properties of binary-relationships. This means that NL queries cannot contain prepositional phrases such as the phrase "in 2004" in the query: "what film was directed by Clint Eastwood in 2004". Existing NL query interfaces to DBpedia cannot handle prepositional phrases; they are also unable to be extended to do so when used with triple-stores other than DBpedia, which can accommodate contextual data. In this thesis, we investigate an alternative approach to querying DBpedia in which NL queries are treated as expressions of the lambda calculus which are evaluated directly with respect to the triple-store using a compositional and extensible denotational semantics of English.


More than thirty years of research demonstrate that there are wide disparities in health throughout America. Health disparities are differences in the incidence/ prevalence/ mortality/ and burden of diseases and other adverse health conditions that exist when specific population subgroups are compared. This course brings in nationally and internationally renown speakers who will examine the social and societal factors that are fundamental in creating disparities in health. The course will focus on the formulation of public policy objectives to reduce and ultimately eliminate health disparities.


As a result of rapid globalisation, there have been some fundamental changes in education due to the rapid changes in knowledge, concepts, technology, and philosophy. COVID-19 has had devastating effects on the education sector. In Nigerian schools, supervisors, teachers, and students have always been required to interact face-to-face before this pandemic. This has led to using electronic facilities to carry out the instruction. Since supervision of instruction plays a vital role in the effective learning outcome. The study, therefore, seeks to investigate the availability and utilisation of electronic supervision of the instruction facilities after the COVID-19 era. A survey design was used to describe the state of e-supervision of instruction using a random sampling technique to select 226 participants from private secondary schools in Education District III, Lagos State. Descriptive and inferential statistics were adopted to establish the availability and utilisation of e-supervision instructions in the post-COVID-19 era. Most of the samples studied (principals, vice-principals, and teachers) demonstrated high levels of access to various tools (both synchronous and asynchronous) used for e-supervision. Effective supervision of teaching and learning will certainly occur in schools with the availability of these tools since COVID-19 has taught teachers how to continue their professions without being hindered by the surge in technology.

The speed estimation technique of induction machines has become a non-trivial task. For estimating the speed of an induction motor precisely and accurately an optimum state estimator is necessary. This paper deals with the performance analysis of induction motor drives using a recursive, optimum state estimator. This technique uses a full order state space Extended Kalman Filter (EKF) model where the rotor flux, rotor speed and stator currents are estimated. A major challenge with induction motor occurs at very low and at near zero speed. In such cases, information about the rotor parameters with respect to stator side become unobservable while using the synchronously rotating reference frame. To overcome this lost coupling effect, EKF observer linearizes the non-linear parameter in every sampling period and estimates the states and machine parameters simultaneously. The proposed algorithm is tuned to obtain least error in estimated speed. Any error found is further optimized using a non-linear fuzzy controller to obtain improved performance of the drive.
