Masonry arch bridges are some of the most common bridge forms in the world. While the majority of these structures are of considerable age, many perform a vital role today carrying roads, rail and services etc. Increased vehicular loads and material deterioration mean that strengthening of existing arches is often required in order to prolong service life. This study will investigate the application of strengthening techniques using fibre reinforced polymer (FRP) composite systems. The application will be explored via numerical modelling using the finite element software package ABAQUS 6.11. The numerical models have been validated with existing experimental test data and are then used to investigate the behaviour of semi-circular masonry arches strengthened with different configurations of FRP e.g. at the intrados, extrados or locally. Then, effects of configuration and amount of FRP on the ductility, strength and global behaviour of strengthened arches will be investigated. Each strengthening system will be compared in terms of increase in strength, ductility, cost and efficiency. Following this, the most efficient strengthening arrangement with the optimum amount of reinforcement will be identified.


The main aim of this study was to examine affective linkages between competition‐related and competition‐extraneous concern domains. A secondary purpose was to establish the contributions of pre‐competition affects to post‐competition performance appraisals, independent of pre‐competition performance expectations. Thirty‐nine highly skilled male martial artists were assessed at five random times a day for a week and 1 h before a major competition on affective states and sources of concern. They also reported their performance expectations and post‐competition performance appraisals. Affective states triggered by competition‐related and competition‐extraneous concerns persisted in time. Carry‐over effects were stronger after reports of competition‐related concerns, emphasizing the subjective importance of the competitive event. Although positive (enjoyment and surprise) and negative (sadness and guilt) affective spill‐over was observed from competition‐extraneous to competition‐related concerns, the reverse held true only for disgust. These findings may be due to the athletes' ability to regulate affective reactions within a sporting setting, in particular. Spill‐over from competition‐extraneous to competition‐related concerns is indicative of a lesser degree of control over work/study and family life. Given that average weekly negative affects and anger/disgust were independent predictors of post‐competition performance appraisals, the phenomenon of spill‐over and other affective linkage mechanisms in sport warrant further investigation.


Introduction: Flossing is the best and most common way to clean between teeth where plaque accumulation and gingivitis starts. However, many mothers the of The purpose of this study was to provide better understanding of perceived barriers of mothers in use of dental floss for their 3-6-year-old children. Method: This qualitative study examined the perceived barriers of 40 mothers of 3-6-year-old children utilizing qualitative content analysis approach. Participants were selected using purposeful sampling in Kamyaran, Iran, in 2014. Data were collected through conducting in-depth, semi-structured interviews. The transcriptions of all interviews were analyzed by content analysis technique to extract main themes in regards to research questions. Results: Mothers' perceived barriers were categorized into two main groups as mother and family member-related barriers (inappropriate attitudes, behaviors and skills, mental and emotional conditions, and knowledge) and child-related barriers (skill). Conclusion: The results of this study highlight the importance of understanding mothers' barriers to help their children in flossing and emphasized the role of mothers and family members in establishing this oral health behavior in children from early years. It is suggested that comprehensive and effective oral health education programs should include modifying wrong, but important, assumptions and beliefs of parents regarding primary teeth and importance of healthy oral health behaviors.


Soil amendments have been found to have a long-term effect on soil either positively or negatively, several soil management researches have been able to establish that sole application of inorganic fertilizer particularly nitrogen fertilizers can leave residual hydrogen ions in the soil which causes soil acidity over time. This study investigated the residual effects of different soil amendments of Palm Oil Mill Effluents (POME), cow dung, and NPK fertilizer, on soil chemical properties in two locations: Ekiti State University Teaching and Research Farm (EKSU) and Onu-Ijelu High School Agricultural Farm. The aim is to evaluate the long-term impact of these commonly used organic and inorganic nutrient sources on soil properties. The research utilizes a randomized complete block deign replicated three times to test the residual effect of the treatments. The research was divided into first and second trial, the result presented here is based on the outcome of the second trial. At the termination of the residual trial, it was found that organic matter contents of soils treated with cow-dung and POME increased while that of the NPK fertilizer reduced. There was a decrease in soil pH on soils treated with NPK fertilizer but found to increase on soils treated with POME and cow-dung. Other nutrient elements including exchangeable cations were also found to increase in soils with POME and Cow-dung. This phenomenon was attributed to mineralization process which made nutrients stored-up in these organic materials to be released slowly and at the same time reducing their loss from the soil. It was concluded that nutrients from organic sources have a longer residual advantage to soil and can be used in combination with inorganic fertilizer for better soil management. The findings from these result provides valuable insights into the long-term effect of these soil amendments and can help farmers and researchers make informed decisions about their appropriate and sustainable use in agriculture.


Abstract With the rapid onset of an unprecedented lifestyle due to the new coronavirus COVID-19 the world academic scene was forced to reform and adapt to the novel circumstances. Although online education cannot be regarded as a groundbreaking endeavour anymore in the21st century, its current character of exclusivity calls for deeper understanding of, and a sharper focus on the "end-consumer" thereof as well as more cautious procedures to be exercised while teaching. While millennials are no longer thought of as being born with a silver spoon in their mouth but with an iPad or any sort of device in their hand (irrespective of their social status), adults are more hesitant when coerced to alter course unexpectedly and turn to new methods of attaining their learning goals. This is why proper communicative approaches need to be thoroughly considered by online instructors. This article aims at presenting teachers with a set of strategies to employ when the beneficiaries of online academic education are adult learners.

A 73-year-old woman with skin phototype VI (black skin, never burns) was referred with a 1-year history of a non-healing, ulcerated lesion on the right instep treated with multiple courses of antibiotics. Twenty years previously the patient had an excision and skin graft of a pigmented mole. No malignancy was seen. Clinical examination revealed a lentiginous area of pigmentation arising medially from the skin graft in addition to a 1-cm pigmented ulcer on the sole (Fig. 1). Full skin examination was otherwise unremarkable and no organomegaly or peripheral lymphadenopathy was identified. Histological analysis of a series of diagnostic punch biopsies showed only an atypical lentiginous melanocytic proliferation. However, a more extensive incisional biopsy from the ulcer confirmed Breslow thickness 1.65-mm acral lentiginous malignant melanoma. The patient has been referred for wide local excision, but has declined sentinel lymph node biopsy. Acral lentiginous malignant melanoma is a cutaneous malignant tumour arising on the palms and soles, accounting for 3–15% of all cutaneous melanomas, but with a particular predilection for dark-skinned ethnic groups. Lesions are commonly misdiagnosed as ulcers, warts or infection and are frequently missed at acral sites, especially in black skin. The prognosis of acral melanoma is poor due in part to diagnostic delay and a high degree of suspicion is prudent. Skin biopsies are prone to sampling error and require careful planning to capture the more subtle histopathological clues. Primary cutaneous melanoma is an increasing public health concern and awareness of its atypical presentations may provide an opportunity for early detection and treatment.


Julie L. Ozanne is the Sonny Merryman Professor of Marketing, Virginia Tech (e-mail: jozanne@ vt. edu). The author appreciates valuable input from Laurel Anderson, Terry Cobb, Brennan Davis, Ron Hill, David Mick, and Lucie Ozanne. The essays in this special issue originated from the second Transformative Consumer Research Conference held at Villanova University in 2009 that Ron Hill, Madhu Viswanathan, and I organized. Transformative consumer research (TCR) is a new academic movement that aims to advance the well-being of consumers through research that employs rigorous theories and methods (Mick 2006). Transformative researchers study the problems most relevant and pressing for consumers and society and then disseminate usable research findings to stakeholders who are best poised for constructive action (Mick et al. 2012). Thus, it is unsurprising that a natural affinity exists between TCR and Journal of Public Policy & Marketing. This journal is one of the finest academic homes for research that aims to advance consumer well-being because of its special relationship to public policy makers who are important agents of social change. In many ways, the 2009 Transformative Consumer Research Conference deviated from the traditional conference format in which scholars present relatively finished research. Instead, the task for the conference participants was to assess the current state of research and then envision future research directions to inspire work on the most important social problems of our time. Scholars who are passionate about and committed to these persistent problems led the tracks: Dipankar Chakravarti and Jose Rosa on poverty; Rohit Deshpande and Cliff Shultz on developing markets; Bill Kilbourne and Andy Prothero on sustainable consumption; Jim Burroughs and Lan Chaplin on materialism; Punam Keller and Debbie Scammon on health; Lauren Block and Sonya Grier on food and well-being; Betsy Moore and Connie Pechmann on at-risk groups; Laurie Anderson and Dave Crockett on immigration, culture, and ethnicity; and Linda Scott and Jerome Williams on social justice. In each track, we also invited either guest scholars with established research records, such as Alan Andreasen, or researchers who hail from related fields, such as Ellen Kennedy from the Center for Genocide and Holocaust Studies. Conference participants earned entrance into these tracks by submitting a bold vision for conducting impactful research on the substantive issue appropriate for their track. To facilitate meaningful exchanges, the tracks were designed to be small, containing approximately a dozen people or fewer. We welcomed more than 100 intrepid researchers to participate in a novel conference format: a dialogical conference where they engaged in a remarkable activity—deeply listening to one another. Encouraged by the gracious financial support of Halloran Philanthropies, which fully funded this conference, we were emboldened to conduct a conference so devoid of the normal trappings of an academic conference, such as formal presentations and luncheons, that this meeting barely resembled a traditional conference at all. For a day and a half, small groups of scholars engaged in dialogue on issues of shared concern. In this essay, I begin by describing this unusual gathering and how colleagues were able to meet with other researchers, in conversation, and then leverage their distributed knowledge to chart new directions for TCR. A dialogical conference was particularly well suited for the tasks facing the TCR community—building a strong social network of researchers, sharing practical wisdom among scholars who seek to translate research into action, and inspiring new scholars on the promise of social change research. I close with a challenge to rethink our traditional notion of research and envision new forms of engaged scholarship based on the premise that we have a stake in forging workable solutions to these important social problems.


Pairing vibrations in strongly rotating nuclei are treated using the variational approach. The residual interaction is assumed to be due to monopole pairing. A simple generalization of the standard BCS plus RPA enables us to obtain the set of mutually dependent equations describing the quasi-particles and the pairing vibrational phonons.


The aim of the present study is to evaluate the in vivo anticancer activity of ethanolic extract of Ficus glomerata on DMBA induced mammary carcinoma in rats. Ficus glomerata Roxb is an indigenous medicinal plant, belonging to the family Moraceae. It is largely used in herbal and herbo-mineral preparation to treat cancer, cardiovascular diseases, asthma, viral hepatitis and diabetes. DMBA at a dose of 20mg/kg body weight (gastric intubation) significantly elevated the xenobiotic markers such as cytochrome P450 reductase and cytochrome b5 reductase in group (II) rats. On the treatments with the ethanolic extract of Ficus glomerata leaf extract (150 mg/kg bw p.o.) significantly decreased these activities in a group (III) rats when compared to DMBA induced rats, which confirmed its anticancer potential. The TCA cycle marker enzymes namely succinate dehydrogenase, malate dehydrogenase, isocitrate dehydrogenase and NADH dehydrogenase were significantly decreased by DMBA induction in group (II) rats, these enzyme levels were reverted to near normal by the supplementation of F. glomerata in group (III) rats. The results of our present study clearly showed that the F. glomerata possess significant anticancer activity.

This study is about youth citizenship in the management of public issues. The study based on considerations related to the demographic situation of the population in Indonesia, which is actually dominated by young people. Especially for this study, young people will be placed in two important areas. First, the citizenship of young people and secondly the citizenship of young people who grow up in the context of a region (city) that is economically growing in a moderate range (Kupang City) and a small town (Bajawa City). The main issue raised in this article is how are the conditions and citizenship of young people growing and developing in response to the public issues around them? The method used in this study is a qualitative method based on in-depth interviews, case studies and discussions involving young people ranging in age from 15-25 years. The results of research in these two areas show a tendency for the involvement of young people in public affairs. First, young people in both regions have the ability to define public issues that they consider important. Second, the tendency to use digital media as a forum for organizing and social movements. Digital media allows children's movements which tend to be small, limited. Third, autonomous movement. This independence is especially strongly influenced by their desire not to be interfered with by other groups. Fourth, diametric relations with the government. Even though their efforts are often considered important by the government, they tend to keep their distance from the government.


A kernel is the most important component of an operating system. The kernel performance determines the overall performance of an operating system. Most importantly, it defines the superiority (not necessarily the popularity) of an operating system over the other operating systems. Furthermore, measuring the kernel performance empowers us to understand the intricate details of an operating system. This understanding helps us in locating potential design flaws and methods that sap the system performance at runtime. Faulty or inefficient methods for key purposes within the kernel, adds to the existing overhead of the applications. To this effect, we present detailed methodologies to measure the kernel performance of the two widely used operating systems – Linux and FreeBSD. We have performed experiments on one computer, configured to run Linux and FreeBSD as a boot-up option. Our experiments indicate that FreeBSD performs better than Linux. We believe that these results provide one more evaluation parameter for an end-user.


Abstract : Recent experience at ESD in acquiring complex computer based systems has identified a deficiency in existing systems management techniques in the area of computer programs. The systems management techniques generally in use were designed for 'equipment' systems and need to be expanded to include computer programs. This paper describes an ESD approach to adapting existing AFSC system management techniques to computer programs. Procedures for insuring system compatibility, design integrity and technical control are discussed and a method for achieving design verification and qualification is presented. Particular emphasis is placed on the relationship of these techniques to computer programs as elements of large computer based systems. The application of these techniques is illustrated through selected examples taken from current ESD system procurements.


The main objective of this work is to propose a new Performance Measure called Agility Rate. This performance measure is related to the ability of producing a large number of different products simultaneously, with a wide range of lot sizes, with insignificant setup times, and achieving all of that with very high resource utilization. We believe that Virtual Enterprises as networks of Autonomous Production Systems are the type of enterprises with the highest potential to have high values of Agility Rate and therefore compete successfully with traditional enterprises. The concept of Autonomous Production Systems and our understanding of Virtual enterprises as well as its operation is also presented here.


Background: Patient benefit from repair of pectus excavatum has mainly been considered psychological although some evidence of physiological benefit has emerged. The purpose of this study was to investigate lung function, respiratory movement and physical fitness together with the patient's satisfaction with the look of the chest one year following modified Nuss procedure. Methods: In this prospective cohort follow-up study eighteen boys and young men who underwent modified Nuss procedure participated. Measurements of lung volumes using spirometry, respiratory movements using Respiratory Movement Measuring Instrument, and physical fitness using Aastrand ergometer bicycle test were performed preand one year post-operatively. Assessment of participants' opinion of the looks of their chest was made at the same point in time. Results: Participants mean age was 16±3 years, their mean BMI was 20.8±3.5 kg/m2 and mean Haller Index was 3.9±0.7. Significant changes one year following modified Nuss procedure were found in mean abdominaland upper thoracic respiratory movements during deep breathing (p≥0.001, p≥0.05, respectively), mean physical fitness (p=0.01) and mean satisfaction with chest looks in general and without shirt (p=0.03, p=0.001 respectively). Conclusion: Increased physical fitness, abdominaland upper thoracic respiratory movements one year following modified Nuss procedure together with high level of patient satisfaction supports the argument that patients benefit from undergoing the repair is physical as well as cosmetic.


Posterior capsule opacification is the most common complication of cataract surgery. Lens epithelial cells remaining in the capsular bag following surgery can undergo epithelial-to-mesenchymal transition and migrate from the anterior to the posterior capsule, leading to fibrosis, capsular wrinkling, and ultimately vision loss. Transforming growth factor-beta 2 has been shown to play a major role in epithelial-to-mesenchymal transition. Covalent tethering of anti-transforming growth factor-beta 2 to the surface of the intraocular lens material may inhibit epithelial-to-mesenchymal transition and the subsequent events, thus leading to a reduction in posterior capsule opacification. In this work, the antibody was tethered to the surface of polydimethylsiloxane as a model lens material via a poly(ethylene) glycol spacer. Surface characterization using a variety of methods demonstrated successful modification. The surface density of the anti-transforming growth factor-beta 2 was approximately 0.5 µg/cm2. The presence of transforming growth factor-beta 2 in cell culture medium stimulated production of extracellular matrix components such as collagen, fibronectin, laminin, and the fibrotic marker α-smooth muscle actin, by HLE-B3 cells. These effects were decreased but not completely eradicated by the presence of the anti-transforming growth factor-beta 2 antibody on the polydimethylsiloxane surface. These results suggest that surface modification with appropriate antifibrotic molecules has the potential to modulate cellular changes following cataract surgery and lead to a reduction in posterior capsule opacification.

A second volume of the important literary legacy of the Golden Jubilee Commission on Telecommunications has recently appeared beside the well-thumbed copy of its sister volume, A Legislative History of the Communications Act of 1934, in the library of every diligent practitioner of communications law. The first volume documents the legislative history of the Communications Act of 1934 ("1934 Act"), which combined the common carrier jurisdiction of the Interstate Commerce Commission with the radio jurisdiction of the Radio Commission to create the Federal Communications Commission ("FCC"). The recently released companion volume, The Communications Act: A Legislative History of the Major Amendments, 1934-1996, brings the legislative history forward to late summer 1998, including the Telecommunications Act of 1996. The first volume was produced under the editorship of the late Max


The application of large-scale grid-connected PV power generation will imperil the stability of grid because of the intermittence and fluctuation of PV. Employing energy storage can smooth the grid-injected power effectively and reduce the influences on grid. The long-term behavior of PV and requirements for connecting PV are taken into account for storage configuration. The power stabilization target is set according to national standard, and an improved configuration method is designed. The annual PV output is traversed and a combination of low-pass filter algorithm and probability statistics is used, and the filter time constant meeting the demand of power stabilization throughout a year is selected. The formulas of storage parameters are obtained, and the storage capacity and storage power allocation quota can be calculated later. The improved method can achieved daily satisfactions of power stabilization and improve the ability of connecting PV power station to be accepted. Example analysis demonstrates the efficiency and feasibility of the method.The research results can provide reference for energy storage configuration of PV farms.


Conducting business by using the internet has become an everyday occurrence in all spheres of economy, as well as in the tourism sector. There is an increasing number of agencies in the world that conduct their business almost completely on-line. The aim of this research was to examine what characterizes the process of implementation of electronic business with tourist agencies in Serbia on the sample of 65 companies, and whether it differs depending on certain business characteristics. For that purpose, EBusTour model was developed that consists of 14 items grouped into four categories: online communication, online promotion, impact on sales and working hours reduction vs. sales improvement. As far as tourist agencies in Serbia are concerned, the results of the application of EBusTour model show that the most common activity in this field is basic online promotion (website implementation), followed by effects on sales. The paper also investigates whether there are differences in e-business implementation in relation to the characteristics such as: years in business, the type of licence (tour operator or sales agent) and the type of market (incoming, outgoing or combined).


Background: As people live longer, they are more likely to die over a prolonged period from incurable, chronic illnesses that occur more frequently in old age. Therefore, people will experience an increase in end-of-life discussions and decisions. Aim: The aim of this study was to explore the prevalence and nature of end-of-life decisions for people with disabilities in Swiss residential homes. Design: A cross-sectional survey in the three biggest German-speaking regions in Switzerland (N = 209) was conducted. Setting: All of the residential homes for adults with disabilities (N = 209) were invited to participate in a cross-sectional survey. The response quote was 76.7%. Directors provided information on 82 deaths. Chi-square and t-tests were used to study differences in prevalence and nature of end-of-life decisions between people with intellectual disability (ID) and people with other disabilities. Results: An end-of-life decision was taken in 53.7% of the cases (n = 44). For people with ID, the decision to withhold treatment had been taken more often (28.9%, 13 cases) than for people with other disabilities (8.1%, 3 cases) (χ2 (1, N = 82) = 5.58, p = 0.017). Conclusion: The study provides insight in end-of-life decision-making for people with disabilities in Switzerland. The results have implications on surrogate decision-making for people with ID living in residential homes. As the study partly confirms the results of previous studies, further studies will be necessary.

Procrastination is a behavior to delay the completion of the task. The postponement also occurred among students of Master of Psychology Program, at Gadjah Mada University. Students exceeded their study time and have not been able to complete their thesis. The purpose of the study was to find out the role of social support, and self-concept clarity as a predictor of thesis writing procrastination behavior. The subject of this research was 115 students. Three scales used to collect the data, were social support scale, self-concept clarity scale, and thesis writing procrastination scale. As conclusion this finding suggests that social support and self-concept clarity may predict thesis writing procrastination, the higher level of social support and self-concept clarity may account for the lower thesis writing procrastination both simultaneously and partially. These findings underscore the importance of social support and self-concept clarity as buffers against the thesis writing procrastination. The category scores obtained by procrastination of thesis writing tend to be moderate, social support tends to be high and self-concept clarity tends to be moderate.


Kidney epithelial cells help to maintain barrier function and selectively allow transport of ions and molecules through transcellular and paracellular routes. In renal epithelial monolayers, transepithelial resistance (TER) shows a stable electrical read‐out and is generally assumed to be an indicator of cellular health and transport. TER represents a composite value of paracellular and transcellular resistance, taken in parallel. We hypothesize that TER values of epithelial monolayers can be a useful parameter to determine transport through paracellular routes in renal epithelial cell lines with high TER values of monolayers and have limitations to determine cell viability. We compared two different kidney epithelial cell lines, a mouse kidney cortical duct cell line, mCCD 1296(d) having high monolayer TER values of around 3 kΩ‐cm2, and Madin‐Darby Canine Kidney (MDCK) epithelial cells, a widely used cell line, having monolayer TER values around 500 Ω‐cm2. Cells were first grown onto permeable membranes and then monolayers were allowed to undergo differentiation. We used Endohm (Ussing) chambers to record TER values of differentiated monolayers. FITC‐conjugated dextran molecules (3 kDa and 70 kDa) were used to quantify transepithelial transport in terms of permeability values. Permeability of 70 kDa dextran molecules estimated the paracellular transport since the transport of these large‐size dextran molecules are restricted only through paracellular routes, not by fluid phase transcytosis. Pearson's correlation showed that the permeability of mCCD monolayers maintained a fair and statistically significant negative correlation with TER values, whereas, MDCK monolayers showed a poor and non‐significant correlation. Therefore, TER values will be useful indicator of the paracellular transport of monolayers of specific renal epithelial cell line having high TER values, such as mCDD cells. Moreover, we recently reported that Hypoxia Inducible Factor 1α (HIF1α) stabilization decreases TER and increases permeability in mCCD monolayers [1]. Surprisingly, in MDCK monolayers, we noticed both TER values and permeability increased due to HIF1α stabilization, supporting that TER is not an ideal parameter to compare paracellular transport of MDCK monolayers.

Significance. The modern trend in the development of medical service providers represents the growing role of the sector of paid medical services and is becoming an important part of the national healthcare market. The purpose of the study is to analyze trends and prospects for the development of private medical activities in the Republic of Tajikistan. Material and methods. The study analyzed the development trend of the private medicine in the Republic of Tajikistan in 2005-2022 based on regulations and statistics of the Ministry of Health and Social Protection of the Population of the Republic of Tajikistan. Results. One of the development indicators of this sphere is the increase in the number of private medical institutions. At present, by January 2023, there are 791 private medical institutions are registered and successfully operating in the Republic of Tajikistan, including legal entities (n=352) with a branch (n=92) totaling to 444 (56.1%), and individuals – 347 (43.9%); compared with the same indicators in 2005 (16 legal entities and 63 individuals) the number increased by 27.7 and about 5.5 times, respectively. The total number of employees in private medical institutions of the Republic of Tajikistan is 4756 (22.9%) people, including doctors – 1919 (40.3% and 9.2% of the total number of doctors in the Republic), paramedical staff – 1840 people (38.7% and 3.0% respectively), auxiliary workers – 1012 people. Private medical institutions account for 7.4% (n=2871) of the total number of hospital beds in the country (n=38726 beds). Over the past two years, the share of paid medical services provided to the population in the Republic of Tajikistan amounted to 455.7 million somoni or 44.7 million U.S. dollars (in 2021 – 250.9 million somoni, for 9 months of 2022 – 204.8 million somoni). Conclusion. At this stage of the development of private medicine in the Republic of Tajikistan, there is an increase in the number of private providers of medical services. Productive interaction between the public health system and private health care providers is essential for improving efficiency of care delivery to the population.

The application of nanomaterials in cement/concrete has resulted in the development of smart materials which are durable, sustainable and high performance oriented apart from being eco-friendly. Several types of nanomaterials are being used by researchers all over the world to improve the properties of cementitious system, amongst them silica nanoparticles (SNPs) have been credited with high pozzolanic reactivity and pore filling effects. It is also very well known that permeability is the major factor for deteriorations of concrete structures in the long term thus affecting its durability. A thorough study was performed on cement mortar composites and standard grade concrete with the additions of colloidal silica nanoparticles(SNPs) in various dosages starting from 0.5%,0.75%,1.0%,1.25% and 1.5% by weight of cement(b.w.c.) to understand the impact from micro-structure improvement to macro-level property enhancement. The results show that in presence of colloidal SNPs (Indian branded) having 35-40% active nano content with 5-40nm particle size the strength increase at 28 days is 32% increasing to 59% at 90 days. An influence on durability is also observed with strength increasing from 4% to 8% with the addition of more SNPs from 0.75% to 1.0% b.w.c. The microstructural investigations reveal that silica nanoparticles refines the pore structure due to accelerated hydrated mechanisms leading to the creation of more hydration products and thus to a more denser microstructure. A M-40 grade standard concrete was prepared as per IS:10262 with the addition of optimized SNPs as found for cement mortar composites strength results at 28 days maximum strength keeping the water-cement(w/c) ratio fixed at 0.4. Tests were conducted on concrete to find out the compressive strength and permeability of concrete. The compressive strength of concrete containing nano materials were found to be 24% more than that of normal cement concrete (NCC) of M-40 grade. The permeability values were found to be decreased by 57% with the addition of nano silica particles to concrete.


A hybrid filter is presented to reduce the CM voltage (CMV) and the differential-mode (DM) harmonics in a three-phase inverter with carrier peak position modulation (CPPM) using RCC control is proposed in this paper. Total harmonic distortion in power electronic system deteriorates the performance of the converters and inverters, many researchers working on power electronic systems to reduce the fault and THD that causes various problems in the power electronic system. In the motor systems driven by sinusoidal pulse width modulation (SPWM) three-phase inverters, the peaks of common-mode (CM) voltage are so high that it will cause many negative effects. Because the use of CPPM strategy in the inverter can ensure that the output CMV will be only two levels in any condition, the simple active CM filter (composed of a half-bridge circuit) in the hybrid filter can effectively suppress the output CMV and CM current. The passive filter in the hybrid filter consists of an added single tuned filter and the original DM low-pass filter.The method which makes use of such ripple and correlates this with switching function to control the operating point of PV array is called ripple correlation control (RCC). In this paper, a modified RCC method has been proposed to implement the MPPT technique with reduced component count which makes the implementation easier compared to existing techniques presented in this paper.By using simulation results the validity of CMV and DM harmonics suppression by the hybrid filter in the three-phase inverter is verified and in the optional schemes the control active CM filter is proved as best one.


I welcorne Avi Bernstein-Nahar's invitation to comment on the interesting roundtable discussion devoted to "The lJses of History in Concemporary Jewish Historical writing." This discussion marks the latest flowering of an important rrend that has surfaced over the past two decades in the field oflewish studies: namely, a reflexive turn characterized by an increased willingness both to study the history of our scholarly forebears and to contemplare the place of our voices in the narratives we construqt. It is not my aim here to dig deeply into the causes of the turn; Suffice it to say that this trend gained momenn]m in the wake of a broader "linguistic turn" in human' ' istic discourse. In the field of histor/, the increased focus on semiotic and rhetoricai formations in'historiographical texts challenged the objectivity claims of their authors, at least in part, by challenging the distinction between fact and fiction' This cirallenge consequently impelled and emboldened authors to implicate th.ms.lv.s rather self-consciously in dre stories they iell-leading to the ,,confessional" impulse that attends much


The design of a microstrip directional response in balancing the ship's Radio and TV distribution system; its dimensions were reduced due to the use of original cells. These elements have many elements such as inductance and capacitance, and the entire structure is smaller than a quarter-wave segment. The design of a transponder with a central frequency of 1 GHz was investigated. Coupler area reduced by 59.4%, but at the same time the number of bands was reduced, when compared with the original design.

In the prefabricated stage of prestressed concrete T-beam,particularly after the imposition of prestressing,a reverse upward deflection (that is inverted camber) will appear;under certain circumstances longitudinal cracks will appear on the edge of the beam.All these problems in the construction process are often difficult to accurately control quantificationally.Taking the 30 metres long-span of prestressed concrete T-beam of the standard plans in the Ministry of Communications for instance,based on finite element theory,adopting the Drucker-Prager creep model in Abaqus,Simulation calculation of prestressed concrete beams reinforced t-shaped in prestressed,temperature gradient and creep of concrete under the action of the inverted camber and longitudinal stress variation。


Active headrest can reduce the low-frequency noise around ears based on the principle of active noise control. This paper presents a combination of robust algorithm and head-tracking for a feedforward active headrest to reduce the broadband noise for a sleeper on a high-speed train. A robust algorithm based on the feedforward active noise control is proposed to improve the noise control performance during head rotations. The head-tracking system with infrared rangefinders tracks the head position based on the Kalman filter to further improve system performance with head movements. Experiments were conducted on a model of a sleeper on a high-speed train. The experimental results show that the proposed active headrest system effectively controls broadband noise with head movements and rotations.


At present, various cities are facing with a number of sustainability challenges in the perspective of climate change. There is a very serious need to reduce the emission of greenhouse gases from cities if determined mitigation targets are to be met. In the meantime, cities are susceptible to the effects of climate change unless adaptation plans can be put in place. The need to connect climate change adaptation and mitigation with broader assessment of sustainability is becoming increasingly documented. The current paper explains an urban integrated assessment facility which pretends socio-economic change, climate impacts and greenhouse gas emissions over the course of the twenty first century at the city scale. The urban integrated assessment facility receives a broad-scale systems approach to develop urban areas and for sustainability assessment. It contains a multisectoral model of the regional economy, hierarchical city-scale spatial interaction model and modules for assessment of climate impacts, adaptation options and greenhouse gas emissions. The given paper shows how the urban integrated assessment facility amounts synergies and conflicts between adaptation to climate change and mitigation of greenhouse gas emissions in order to improve decision making and facilitate the development of portfolios of planning policies that together have a realistic prospect of achieving sustainable outcomes for cities.


The paper presents expert systems as a new generation of information storage and retrieval systems which may consider ably improve the processes of scientific and technical informa tion exchange and dissemination. Essential features of the expert systems with databases containing scientific or technical information have been specified. For databases in which a semantic network is used as a knowledge representation scheme, an idea of database organization has been described with some attention paid to the problem of extracting factual information from the texts of scientific and technical publications. The process of information retrieval from the database of a scien tific or technical information expert system has also been briefly described.


Recently, we have read the original article written by Yaling Lu et al1 , which was published in European Journal of Neurology [1]. The authors enrolled 635 acute ischemic stroke patients with soluble suppression of tumorigenicity 2 (sST2) measurements from the China Antihypertensive Trial in Acute Ischemic Stroke, one multicenter randomized clinical trial in China, to explore the relationship between sST2 and post-stroke depression (PSD).


This paper addresses the problem of mapping three dimensional environments from a sequence of images taken by a calibrated camera, and simultaneously generating the camera motion trajectory. This is the Monocular SLAM problem in robotics, and is akin to the Structure from Motion (SFM) problem in computer vision. We present a novel map-aided 6-DOF relative pose estimation method based on a new formulation of the Monocular SLAM that is able to provide better initial estimates of new camera poses than the simple triangulation traditionally used in this context. The '6-DOF' means relative to the map which itself is up to an unobservable scale. The proposed pose estimator also allows more effective outlier rejection in matching features present in the map and features extracted from two consecutive images. Our Monocular SLAM algorithm is able to deal with arbitrary camera motion, making the smooth motion assumption, which is required by the typically used constant velocity model, unnecessary. In the new Monocular SLAM formulation, the measurements of extracted features from images are partitioned into those used for the estimation of the environment and those used for estimating the camera motion. The new formulation enables the current map estimate to aid achieving the full 6-DOF relative pose estimation up to the mapping scale while maximally exploiting the geometry information in images. Experiment results are provided to verify the proposed algorithm.


Water was determined with a wide line NMR instrument. Three soy flours were studied: full-fat Bonus variety; laboratory, chloroform-methanol defatted from the same Bonus sample; and commercial, hexane defatted. In case of all three samples, a plot of moisture content vs NMR response at rf 28 db (total water) showed two straight lines; the break occurred at the Bound Water Capacity (BWC). At an instrument setting of rf 0 db (only bound water gives signal), a plot of signal against moisture content, both on a total sample basis, was a triangle; the first increment of water, 3 and 7% for full-fat and defatted, respectively, did not give a signal and the apex of the triangle gave the BWC which was 27.9% for the full-fat and 40.5% for the same soy flour after defatting. When laboratory and commercially defatted samples were compared, the ascending curves coincided but their BWC were 40 and 31%, respectively. BWC values obtained from full-fat readings corrected for oil signal and from commercially defatted flakes were almost the same. Steam heating at 15 psig for 15 min and freezing to a temperature as low as -40°C did not change the water binding characteristics of commercial defatted dry flakes.


Hypoxic pulmonary vasoconstriction (HPV) is a local and adaptive response to alveolar hypoxia causing constriction of small pulmonary arteries, thereby reducing perfusion to underventilated alveoli. However, in pathological conditions characterised by global and persistent hypoxia, such as chronic obstructive pulmonary disease (COPD), this physiological mechanism that normally serves to optimise ventilation–perfusion matching become damaging, promoting sustained pulmonary vasoconstriction and vascular remodelling [1]. These structural changes are accompanied by a gradual increase of pulmonary arterial pressure, ultimately leading to right ventricular (RV) hypertrophy and failure. Although there is a global consensus amongst scientists that elevation of the intracellular calcium concentration plays a critical role in producing HPV, the precise underlying mechanisms (e.g. nature of the oxygen sensor, direction of changes in reactive oxygen species (ROS) as well as how ROS production affects the activity of calcium channels) and even the cell type involved remain a subject of ongoing debate [2–4]. A study published in the ERJ investigates the role of superoxide in adaptation of the pulmonary vasculature to chronic hypoxia and adaptation of the right ventricle to increased afterload http://ow.ly/Dj9Q30iwO8R


Soekarno was one of the figures of the National movement that fought against the Dutch. He played a very important role in advancing the nation of Indonesia. Soekarno also joined the Sarekat Muhammadiyah. His encounter with the founder of Sarekat Muhammadiyah began when he was in Surabaya. When he was exiled to Bengkulu, the Sarekat Muhammadiyah was used as a means of fighting for the Indonesian nation. One of his role in Muhammadiyah in Bengkulu was eradicated the customs of Muhammadiyah people in putting restrictions on men and women when conducting meetings. He also established a conference of Daeratul Kubro in the Sumatra region, in addition to creating PEKOPE (War Victims Assistance) in order to welcome Japan to Japan Indonesia. This is a library research using a historical research method consisting of heuristics while the data was obtained by referring to an autiobiography of Soekarno entitled Soekarno Penyambung Lidah Rakyat Indonesia. This research found that Soekarno made some contributions to the development of Muhammadiyah in Bengkulu through initiatives that he made in efforts to struggle for the Indonesia's independence. Keywords: Soekarno, Indonesia's Independence, Muhammadiyah, Bengkulu


High end video applications are still implemented in hardware consisting of many components. Integration of these components on one IC is difficult as they are typically low volume products and often customization is also required, e.g. in studio applications. This is easier on the board level than on an integrated system. Using hardware parameters for customization can partly overcome the flexibility problem with additional hardware costs. Low cost can be obtained by a change in the architecture paradigm to a processor-coprocessor system. This, however, requires careful design space exploration since the performance target is beyond current DSP processors while at the same time flexibility is required. The paper presents the application of high level synthesis (D.D. Gajski et al., 1992) and novel hardware-software cosynthesis tools to design space exploration. It is shown that completely different algorithms can be mapped to the same target system at a much lower cost than the current approaches.


Expressions connected to friendship and brotherhood were a prominent part of letter‐writing in the 16th century. They did not necessarily describe the true nature of a given relationship, but can rather be seen as a strategy, as a means to refer to shared values and norms related to friendship. Among noblemen, appealing to friendship was the main way of justifying requests. This reveals a connection between the rhetoric of friendship and power. Along with an emotional bond or a supporting network, friendship can be examined as a cultural ideal, which could be utilized rhetorically to produce and exercise power.


This chapter addresses the issue of the limitation of the knowability of particular finite things. Focusing on 2p8 and 2p9, the chapter discerns two sorts of limitations: the empirical origin of the existence of particular objects and the local determination of events. Neither of these limitations undermines the universal validity of the rationalist principle of the intelligibility of any being. Nevertheless, they establish conditions of possibility for the notion of understanding or intellection itself. Rather than being concerned with the paradoxical notion of infinite perspective, Spinoza's introduction of these limitations posits that the perspective from which particular objects or events may be understood must itself be temporally or locally determined. This also touches upon the explanation of experience: any instance of experience must be viewed from a particular perspective in order to be comprehended.


Kanikka means something in Hinduism, Sanskrit, the history of ancient India, Jainism, Prakrit. So many as 22 QR codes have been displayed at various locations in the temple complex and nearby areas through which the devotees can offer the kannikka. As the annual pilgrimage is progressing at the famed Lord Ayyappa temple in Kerala, the Travancore Devaswom Board (TDB), the apex temple body, has made arrangements for devotees to offer 'e-kanikka' at the electronic hundi collection in the temple complex and nearby areas. As in the previous years, the arrangements for the digital payment was made in association with the Dhanlaxmi Bank, who are the official bankers of the TDB this year as well.


What can do the markets? This article examines through the light of current and recent past the contributions and limits of agricultural futures markets. Despite the crisis of agricultural raw materials, the markets seem to have very well played their role. If developed countries must stay under the discipline of markets, despite their tendancy to "irrational exuberance" one must recognize that markets do not ensure the development of poor countries. So, it is necessary to allow those countries to deploy autonomous agricultural policies, which means that they can protect themselves from fluctuations in external markets.


Petroleum oils are insufficient in lubricating our engines since they are made of refined substance, since some of the chemicals present in conventional petroleum oil break down at temperatures within the normal range usually around 325 to 250 degree Fahrenheit. Synthetic Oil outperforms all brands of petroleum oil in every aspect, but the best benefit we can derived from continuous use of synthetic oil is the extended life of your vehicle. Synthetic oil will make your engine last longer that petroleum oil through its continuous use. Throughout its history, the diesel has been the subject of a great deal of research and development. This work has focused on comparative study of physical properties Synthetic Oil and Mineral Oil.

Abstract. From the analysis of the taphonomic attributes of the specimens of Heleobia parchappii found in fluvial and paleolacustrine sequences of the lower basin of the Salado River, the surface alteration of their shells was comparatively studied in order to assess the differences between both environments. The main results that were obtained by means of Non-Metric Multidimensional Scaling (NMDS) and analysis of similarity (ANOSIM) tests (R=0.31, p<0.01) enabled the recognition and statistical differentiation of both groups of samples. The taphonomic characteristics presented by those that were recovered from the paleolacustrine environment are more similar to each other, whereas those from the fluvial environment showed greater dispersion. Through the similarity percentage (SIMPER) analysis we could determine that the variables of discoloration and dissolution were the most important features to differentiate both groups, and that the values of the indexes (Total Taphonomic Grades) were always higher in the paleolacustrine assemblages, thus showing greater decay. The differences of preservation could be explained by the residence time of the remains near the water-sediment interface as well as by the differences in the sedimentation rate in both environments, which control the different exposure cycles of the shells. These differences would be related to changes in the hydrological regime (fluctuations in surface and groundwater levels) that, although affecting the entire study area, are more intense and frequent in shallow lakes, therefore favoring the decay of the shells accumulated in this environment.


The invention discloses a piezoelectric self-sensing based adjustable damper. The piezoelectric self-sensing based adjustable damper comprises an upper lifting lug, a dustproof cover, a piston rod, a guide seat assembly, a working cylinder barrel, a working piston assembly, a seal ring, a floating piston, a closed air chamber and a lower lifting lug, wherein the working piston assembly comprises a compression block, a limiting block, a limiting rod, a piezoelectric valve plate, a piston, a flow valve, a piston packing ring, a rebound valve, a preset normal open hole and a compression nut; the piezoelectric valve plate is formed by connecting a plurality of piezoelectric displacement units in series; each piezoelectric displacement unit is composed of a piezoelectric material stack layer and a displacement enlargement mechanism. The piezoelectric valve plate generates induced charge under the action of oil pressure, extracts induced voltage and exerts control voltage via a bridge circuit to change the size of the valve plate so that the size of a throttling area changes and a damping coefficient is adjustable. Based on the piezoelectric self-sensing effect, a sensor and an actuator are integrated on the same valve plate, the piezoelectric self-sensing based adjustable damper is simplified in structure, stable to control and high in dynamic response speed, and the capacity coupling is avoided.


At the Superconducting Darmstadt Linear Accelerator S-DALINAC [1] it is possible to accelerate electron beams to a maximum energy of up to 130 MeV with a beam current of up to 20 μA. In the S-DALINAC Polarized Injector SPIN [2] polarized electrons with a polarization of up to 86% can be produced. The polarization can be measured with two already mounted Mott polarimeters in the injector beam line, where the electrons can have energies of up to 10 MeV. To allow a polarization measurement behind the main accelerator a Møller polarimeter suitable for energies between 50 MeV and 130 MeV is currently being developed. The rather low and variable beam energies and the resulting big and also variable scattering angle distribution combined with very strict spatial boundary conditions at the designated mounting area necessitate a very compact set-up for the polarimeter.


Hemoglobin (Hb) toxicity precipitates secondary brain damage following intracerebral hemorrhage (ICH). CD163 is an anti-inflammatory Hb scavenger receptor and CD163-positive macrophages/microglia locally accumulate post-bleed, yet no studies have investigated the role of CD163 after ICH. ICH was induced in wildtype and CD163−/− mice and various anatomical and functional outcomes were assessed. At 3 d, CD163−/− mice have 43.4 ± 5.0% (p = 0.0002) and 34.8 ± 3.4% (p = 0.0003) less hematoma volume and tissue injury, respectively. Whereas, at 10 d, CD163−/− mice have 49.2 ± 15.0% larger lesions (p = 0.0385). An inflection point was identified, where CD163−/− mice perform better on neurobehavioral testing and have less mortality before 4 d, but increased mortality and worse function after 4 d (p = 0.0389). At 3 d, CD163−/− mice have less Hb, iron, and blood–brain barrier dysfunction, increased astrogliosis and neovascularization, and no change in heme oxygenase 1 (HO1) expression. At 10 d, CD163−/− mice have increased iron and VEGF immunoreactivity, but no significant change in HO1 or astrogliosis. These novel findings reveal that CD163 deficiency has distinct temporal influences following ICH, with early beneficial properties but delayed injurious effects. While it is unclear why CD163 deficiency is initially beneficial, the late injurious effects are consistent with the key anti-inflammatory role of CD163 in the recovery phase of tissue damage.


This paper discusses application of glass-fiber-reinforced plastic(GFRP) in a foundation pit support instead of conventional material.The laboratory studies on the mechanical properties of the GFRP beams with different sections were carried out.Their mechanical behavior and the failure features are described and analyzed.The test results indicate that the material properties and the stability of the GFRP middle beam and the local strength at the joint between web and flange are the main factors in the composite middle beam designing.The optimal selection of the GFRP middle beam section should satisfy the requirements of both globe and local stabilities simultaneously,the material strengths of the middle beam should fully be utilized.The composite material of I-section with double webs is the best section type for the middle beam.Local strengthening should be adopted in the middle beam-bolt joint.


The change in mechanochemical behavior of basic magnesium carbonate (4MgCO3·Mg(OH)2·4H2O) caused by vibrational grinding was investigated by means of the scanning electron microscopy (SEM), specific surface area measurement, X-ray diffractometry, infrared absorption spectroscopy, and thermoanalysis.It was found that the generation of fine particles and their granulation occurred in grinding from the observation in SEM. The specific surface area showed the maximum value at 20min, and decreased to a constant value after prolonged grinding.It was found from the powder X-ray diffraction patterns of the ground basic magnesium carbonate that the structural lattice irregularity and an amorphous phase were formed by grinding, and their amounts increased gradually with increasing grinding time.The effect of grinding on the pyrolysis of basic magnesium carbonate was also studied. From the X-ray diffraction patterns of the products made by pyrolyzing the original basic magnesium carbonate and the ground one at the heating rate of 2°C/min, it was found that the crystallized MgCO3 was produced in the dehydration reaction of the ground basic magnesium carbonate, while MgCO3 produced by the dehydration of the original basic magnesium carbonate was only the amorphous phase. It was also found from the result of thermoanalysis that the reaction rate of dehydration of the ground basic magnesium carbonate was higher than that of the original basic magnesium carbonate, whereas the reaction rate of decarbonation of the ground basic magnesium carbonate was lower than that of the original basic magnesium carbonate.


We undertook this study to evaluate the activation and functional relevance of inflammasome pathways in ankylosing spondylitis (AS) patients and rodent models and their relationship to dysbiosis.


A chirped long-period grating inscribed in a planer optical waveguide sensor is demonstrated. The distribution of electric field within the structure has been obtained using boundary condition for the electric field equations at different dielectric boundaries. The transmission spectrum of the proposed sensor is obtained by transfer-matrix method. Further, the sensitivity for ambient refractive index and temperature has been analysed by observing the shift in resonance wavelengths. The presence of two dips in the transmission spectrum effectively doubles the sensitivity in comparison to the single resonance structure. We have achieved refractive index sensitivity of 5600 nm/RIU and temperature sensitivity of 0.8 nm/ °C, respectively.

Population of small rodents in radiocontaminated environment is compelled to include more energy-intensive way of maintenance its ability to live — increasing of the proportion of mature young of the year (first pathway of ontogeny). Their reproductive characteristics — actual fecundity was higher, whereas embryonic mortality and the proportion of females with embryonic losses were significantly lower compared with neighboring areas. Abundance of mice in the impact zone was higher, age cross was revealed, which improves the adaptive possibility of the population. Preconditions for acceleration of evolutionary transformations of a population are created, but this process is restrained by both the local configuration of the polluted territory and migration of murine rodents. As a consequence, the population decreases the probability that certain changes will be fixed and inherited in a series of generations. Chronic low-dose radiation (stress) can be considered as the mechanism of switching of life history of cyclomorphic mammals. Thus, ontogenetic multiversality of small mammals is an important mechanism of protection strategy of population and decreasing the damaging action on biota in radiocontaminated environment. Functional approach makes it possible to reduce errors in assessing the radiological consequences and hence, can provide a reliable methodological basis for organization of biological monitoring.


In anticipation of the experimental comparisons to be given in Part III, the grand partition function is employed to derive the isotherm and the two‐dimensional equation of state corresponding to a model of localized monolayer adsorption similar to that of Rushbrooke, in which the lateral vibrational partition function is permitted to depend on the occupation number of neighboring sites. This treatment includes the Fowler ``crude'' isotherm as a special case. As a competing theory, a parallel development is given for the van der Waals model of mobile adsorption. Equations are presented for the critical parameters, and for the determination of the coexistence curves for these models. Finally, graphical comparisons are made which demonstrate the experimental distinguishability of the three theories on plots which rectilinearize one at a time.


Covid-19 has radically upended death and dying. Restrictive measures aimed at containing the spread of infections have resulted in a simplification or abandonment of many social and cultural practices related to burials, funerals and mourning. This article aims to examine how the pandemic has affected burials, funeral practices and mourning. It analyses the extent to which the restrictions balance the need to protect public health and the opportunity for mourners to honour the deceased. A consideration of the implications for surviving families and the wider community is important for future pandemic preparations.
Keywords: pandemic; death; burial; funeral; grief; mourning.


The EtOH extracts of red seaweeds (Symphyocladia latiuscula, Chondrus ocellatus and Carpopeltis affinis) and solvent partitioned fractions were investigated for their 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effects and the total phenolic contents were correlated with ABTS and DPPH radical scavenging activities. The EtOH extracts and their solvent partitioned fractions exhibited strong ABTS and DPPH radical scavenging activities. Among the solvent partitioned fractions obtained from n-Hexane (HX), methylenchloride (MC), ethylacetate (EA), and buthanol (BuOH), the HX fraction from C. affinis showed higher radical scavenging activities than other fractions. Total phenolic contents showed significant correlation (r² = 0.709) with ABTS radical scavenging activity. The results of this study suggest that the strong radical scavenging activity of HX fraction from C. affinis is a promising natural antioxidant for healthcare products.


A 61-year-old man with end-stage renal failure resulting from polycystic disease (hepatic and renal) who was on hemodialysis was investigated because of the development of ascites. During the previous 2 months, he had extremely high levels of carbohydrate antigen (CA) 19-9 (4951.1 U/mL normal range, 0–37 U/mL ) and CA 50 (4365.6 U/mL normal range, 0–25 U/mL ). Ultrasound, CT, and MRI, as well as endoscopy, were negative for tumor. He was referred to our Nuclear Medicine Department to be investigated for a possible neuroendocrine pancreatic tumor by In-111 pentetreotide scintigraphy. An upward displacement of the diaphragm into the thorax was noted such that the spleen appeared in the left lower lung field and the liver at the site of the right lower lung field. These topographic changes were explained by the ascites.


Self-growth refers to that individuals' acceptance of themselves will be promoted; their self-worth will be improved and ultimately their overall level of mental health will be enhanced through the self-awareness and self-recognition. According to the present teaching situation of applied psy- chology curriculum, this study put forward the content and target of the teaching mode consider- ing students' self-growth, provided four methods to promote students' self-growth and gave four proposals that should be paid attention to during the teaching. Using the questionnaire survey and the interview, the study collected the data. The results indicated that the teaching mode consider- ing students' self-growth was feasible and effective. The teaching mode guaranteed the teaching effect and quality of applied psychology curriculum, and at the same time, it strengthened the cultivation of student's self-growth and provided more possibilities for applied psychology courses.


IN social surveys and regional townplanning schemes it is invariably assumed that the geographer is primarily concerned with the physical ground-plan on which the city rests. It is sometimes further conceded that the geographer follows such appraisal by tracing the effects of this physical ground-plan on the growth and character of the city, but as a rule the investigation of these pal ticular aspects is handled by the economist, sociologist, historian, or architect. There are, howevei, numerous thorough studies of cities by geographers, which indicate clearly that urban geography has a well established scope and special techniques. It seems necessary, therefore, to assess the contribution of geography to the study of the city as revealed in such studies in order to indicate to the geographer the status of the subject and to suggest lines of future investigation. Such a review will also demonstrate to the student of


Trans fatty acid(TFA)is generic name of a type of unsaturated fatty acid that contains trans double bond configuration.

The paper summarized resources,hazards,detection methods of trans fatty acid and made a prospect for its research directions.


Currently many training systems acquired, fielded and sustained by the U.S. Army are unable to seamlessly comply with a continuously evolving and often complex computational environment. The current state of such training systems must advance to a Training as a Service (TaaS) future state in order to adapt to a volatile defense budget, conform to policy updates, and enhance the training capabilities afforded to the War fighter. TaaS will transform current Army training applications into distributed web-based services, allowing them to be accessible across any location via thin client workstations and wireless mobile devices. The motivation behind this migration is coming from the Common Operating Environment (COE) Architecture Guidance published by the U.S. Army Chief Information Officer and the Assistant Secretary of the Army for Acquisition, Logistics, and Technology. In order to achieve the COE objectives, the Army recently launched a pilot study on the Common Training Instrumentation Architecture (CTIA). CTIA is the foundation architecture of the Army's Live Training Transformation (LT2) Product Line that provides software infrastructure and services to live training product applications. This paper describes the migration of CTIA to TaaS using a specific set of modern computing technologies that will enable rapid delivery of training capabilities across servers, mobile devices, and heterogeneous platforms. Specifically service-oriented architecture (SOA) and cloud computing are considered which can satisfy the requirements of the TaaS and COE, and meet user demands for an enhanced training experience. Furthermore, this paper discusses the approach taken to elicit the future needs of the Army's live training community, and how cloud computing and SOA are leveraged to meet required capabilities. Lastly, this paper discusses some unique considerations on SOA-related security issues.

With recent advances in stent technology, the everevolving field of interventional cardiology has conquered many complex coronary lesions (i.e. bypass grafts, left main stems, diffuse lesions, bifurcations, and in-stent restenotic lesions). One of the last untamed bastión is to cross successfully a chronic total occlusion (CTO). During the last two decades, CTO lesions have presented the toughest challenge for treatment, with lower success rates and higher complication rates than any other coronary lesion type. CTO procedures usually last much longer than conventional percutaneous coronary intervention (PCI), and are coupled with an increased exposure to radiation and contrast. Furthermore, failure to tackle CTO lesions translates into frequent surgical referral, incomplete percutaneous revascularization, with suboptimal long-term results probably close to medical therapy but definitely worse than surgery. In the meantime, clinical indication for CTO-PCI is under scrutiny [1–3]. Besides, the recently published ACCF/SCAI/STS/AATS/AHA/ASNC 2009 Appropriateness Criteria for Coronary Revascularization may not endorse CTO revascularization on various situations, especially for asymptomatic patients [4]. At present, several Japanese operators with great experience in CTO-PCI are capable of successfully recanalize >90% of CTO lesions [5]. Naturally their experience is based on high CTO attempt rates [5], whereas in USA national CTO attempt rate is surprisingly low (11.8%) [6]. Successful treatment of impossible CTOs depends on judicious material selection from a host of CTO niche devices available (i.e. dedicated CTO guidewires and microcatheters), and appropriate handling of various guidewire techniques [i.e. parallel wire, intravascular ultrasound (IVUS) guided wiring, retrograde, controlled antegrade and retrograde tracking, and kissing wire technique among others]. Rathore et al. in this issue report two complex CTO cases successfully crossed with adjunctive IVUS guiding [7]. In the first case, the authors were unable to cross an occluded LCX by standard antegrade guidewire manipulation, decided to place an IVUS on a left atrial branch, and performed pullback up to the left main stem. IVUS imaging clearly demarcated the entry point, and the authors crossed the occlusion with tapered stiff guidewires and parallel wire technique. In the second case, a proximal LAD CTO (recent failed attempt 8 weeks earlier), could not be crossed with a stiff guidewire reaching the subintimal space. Retrograde approach was also unsuccessful. The authors placed the IVUS in the subintimal space and localized the entry point, which enabled successful crossing of an extremely challenging CTO. Although it is not mandatory to use IVUS during CTO-PCI, it can be very instrumental. IVUS imaging can help differentiate a true lumen from subintimal space by identifying the presence of side branches, intima and media (found in the true lumen, but not in the subintimal space). In addition, IVUS can confirm guidewire re-entry to the true lumen from the subintimal space. IVUS guided wiring technique may constitute one of the last alternatives in the antegrade approach when standard wiring procedures fail in cases without a chance of retrograde approach [8]. Although complex CTO-PCI techniques are fascinating, they are chiefly performed in Japan and some academic European centers. Worldwide, our community is hesitant to embrace these techniques because, even for senior operators, extensive training is required to master impossible CTOs.

Hypertension is the number one disease in Indonesia, reaching 25.8% and most cases of hypertension in the community have not been detected. One of the non-pharmacological therapies to treat high blood pressure is Ambon banana which is high in potassium. The purpose of this study was to determine the effect of Ambon banana on changes in blood pressure in patients with hypertension and its comparison with the positive control group in the work area of Lubuk Buaya Padang Health Center in 2019.
This research is an experimental research, this type of research is one group pretets-post tets. The sample approach on 20 hypertensive respondents used was the purposive sampling method. Divided into two groups, the treatment group that was given Ambon banana was 300 gr a day, measured before and after treatment and the control group, the experiment was carried out for 7 days.
The t-test results of the systolic treatment group before and after showing p value 0,000 and diastolic p value 0,004. This shows significantly the effect of Ambon banana on blood pressure. In the control group also experienced changes but not significant with a difference of 0.5% from the value of p <0.05. Banana Ambon can reduce hypertension because it contains high potassium which works similar to antihypertensive drugs in the human body.
It is recommended to the health center to provide health counseling regarding nonphamacological treatment regarding ambon banana and its effect on the reduction of blood pressure in pre elderly hypertension.


Hyperostosis of the skull associated with an underlying fibroblastoma has been reported in a good many instances. It is recognized that in a small number of cases of fibroblastoma of the meninges there is an accompanying cranial thickening, with the presence of tumor cells within the thickened bone. The mechanism involved in the production of hyperostosis is still unsettled, but the clinical fact remains that hyperostosis and a subjacent fibroblastoma are sometimes associated. That an extensive thickening of the cranium may result from a fibroblastoma lying on the skull has not as yet been recognized. It is for this reason that we record an unusual case in which there was a fibroblastoma lying on the skull, accompanied by a pronounced hyperostosis of the underlying bone. This is the first example of this sort of which we are aware. Trauma seemed to play a role in the formation of the tumor


Sarah Rubidge (PhD) is a choreographer and digital installation artist. Most of her work has been developed in close collaboration with other artists and over the years has covered a variety of genres, from contemporary dance work, through music-theatre works, mixed media performance and large-scale digital installations. Much of her work is site specific. The focus of her artistic work now lies in the dialogue between dance and new technologies, in particular in interactive installation work. Some focus on audience-directed interactivity, some involve a performance element, some combine the two. At present she is particularly interested in developing installation spaces in which a sense of the environment is absorbed through the body, from the perspective of inhabitant of the environment rather than that of viewer. She is also interested in developing performative installation spaces in which the participants movements become an integral element of the work itself. Her installation works include: Passing Phases, with Garry Hill, Tim Diggins and Nye Parry; Halo, with Simon Biggs and Stuart Jones; Time & Tide with Jane Rees; Hidden Histories with Joseph Hyde; Sensuous Geographies (2003) with Alistair MacDonald. In 2001 Sarah was awarded a three year Research Fellowship in the Creative and Performing Arts by the Arts and Humanities Research Board to pursue her work with interactive/responsive digital installations. She is currently Research Fellow at University College Chichester, where she teaches undergraduate and postgraduate courses in Performance and Technology and supervises practice-based PhDs. She also conducts international workshops in performance and technology.(www.sensedigital.co.uk).


This chapter studies the incidence impact of the 2008–09 global financial crisis on Brazil and Mexico. During the last decade, Mexico has been on a slow growth path, whereas Brazil has enjoyed a sustained and accelerating expansion of its economy, accompanied by a reduction in income inequality. Because of its close commercial ties with the United States, Mexico was much more severely affected by the global crisis than Brazil, which not only trades with a more diversified set of countries, but also exports commodities and agricultural goods whose demand and prices were less affected by the crisis. During 2009, the gross domestic product (GDP) of Mexico contracted by about 6 percent but only 0.3 percent in Brazil. Compared with a counterfactual—no-crisis—scenario, Mexico lost about 9 percentage points of its GDP (instead of growing by 2.8 percent in 2009, it contracted by 6.2 percent), whereas Brazil lost 4 percentage points. The size of the crisis has thus been very different across these two countries and that is reflected in the much larger rise in poverty in Mexico than in Brazil.


Aim of the work: Animal urine, including that of camels, has long been used for the therapeutic management of human ailments. In this study, we sought to characterize the cytotoxic properties of newly derived purified fractions from previously described camel urine extract (PMF) on various cancer cell lines. Methodology: Two new size dissimilar fractions of PMF (large and small) were obtained by fractionalizing PMF using 3kD and 50kD membrane filters. A SRB cyt otoxicity assay of the PMF


Downy mildew (DM) of opium poppy ( Papaver somniferum ) caused by Peronospora somniferi is one of the most destructive diseases of this crop due to the systemic nature of infection as compared with local infections caused by Peronospora meconopsidis , the other downy mildew pathogen of this crop. We developed an inoculation method using Peronospora somniferi sporangia as inoculum and demonstrated for the first time that local infection of leaves by sporangia give rise to systemic infections in the plant as well as of seeds. Our results also showed that this inoculation protocol was very effective in reproducing disease symptoms and assessing the resistance response to DM in opium poppy genotypes under field conditions. More interestingly, results indicate that up to 100% of seed samples from some genotypes showing a complete (symptomless) resistant phenotype were infected by the pathogen when seeds were analyzed by a P. somniferi- specific nested-PCR protocol. This latter aspect deserves further attention while breeding opium poppy for resistance to P. somniferi.

Abstract Laser-induced fluorescence and resonant two-photon ionization techniques have been combined to study the H 3 Σ − u state of Si 2 . A measurement of the isotope-induced bandhead shifts reveals that the previously accepted vibrational numbering of the H 3 Σ − u state is incorrect. Revised molecular constants based on the new vibrational numbering scheme are T e = 24 151.86 cm −1 , ω e = 279.28 cm −1 , ω e χ e = 1.99 cm −1 , B e = 0.17255 cm −1 , and α e = 0.00135 cm −1 . Lower bound measurements of the H 3 Σ − u , radiative lifetime ( P T ∼ 1500 m Torr) are reported. Resonant two-photon ionization of the H 3 Σ − u state has allowed the bracketing of the Si 2 ionization potential between 7.9 and 8.1 eV.

Overview Containerization and microservice architectures provide an infrastructure that can support the realization of many requests of the IT world, including faster time to market for products and supporting technologies features, scalable services, and improved customer experience through reduced downtime and upgrade processes. Some companies have seen many-fold increases in feature velocity with the potential of tens if not hundreds of feature and fix releases of software both for customer facing and internal use cases. However the road to these values is not always straightforward, given that not all software can simply be containerized and therefore run like a microservice system.


The following paper illustrates the usage of modern educational tools in teaching dynamics to students of engineering technology. Problems in engineering technology are traditionally skill based rather than theory based. As a result the instructor has to illustrate problems keeping the hands-on approach in mind. One of the best ways to exemplify theory, to meet the above requirements, is the usage of modern educational tools like multimedia, simulation software and visualization techniques. This helps the students to understand the engineering aspect of dynamics from the pure science aspect of the subject matterÐa key feature in satisfying our program requirement.


International airport is an important symbol of a modernized metropolis.Many metropolises are planning to construct international airports.Especially in the Super Urban Agglomeration of China and the Dense City and Town Areas,for example,the Pearl River delta Urban Agglomeration.International airport has the modernized airdrome facility and the international space location superiority,which adapts to the national economic scale.She is one of the most important symbols of national modernization,also is the most concrete manifestation of spatial characteristics for a modernized international metropolis.The international airport is important aviation hinge for the world economics and society development highly and the industrialization society's supporting network,and also is the important gathering center and junction in some important countries and large areas with the whole globe economic integration.Under the background of the economic globalization,the new characteristics of industrialization,urbanization and internationalization in our country increasingly reveal.Along with the expansion of international market,between countries the flowing amount of passengers,goods and information increases continually.Between the cities economic function changes from the vertical division of labor into the level division of labor primarily,which has accelerated construction and expansion of the international airport.For recent 10 years besides international airports in Beijing and Shanghai our country has constructed and expanded White Clouds Airport in Guangzhou,Taoxian Airport in Shenyang,Lukou Airport in Nanjing and Xiaoshan airport in Hangzhou and so on,which is precisely our positive effect and the long term demand that adapt to the globalization development tendency and the internationalization.This paper takes New White Clouds Airport in Guangzhou as an example to discuss the developing background,location selection,planning principle,modernized facilities of international airport and the interaction between international airports and the master planning of metropolis,and tries to arouse the interests in this field.As a complex system,the urban transportation system has been analyzed,and then from a new viewpoint an image model of urban system structure is introduced,and from the viewpoint of a complex system the basic characteristics,such as objectiveness,incidence,environment and dynamic ability,have been discussed.
