INTRODUCTION Cementless Total Hip Replacement surgery is a well established procedure for relative young patients with severe hip disease. Excellent long term clinical results have been published on the performance of the femoral component. With growing clinical experience, our concern focused on excessive wear of the Ultra High Molecular Weight Polyethylene (UHMWPE) ringloc liner of the Mallory Head cementless Total Hip Prosthesis. After its introduction in our clinic in 1997, this implant is still in use without any modification. We were concerned that due to premature liner wear, the performance of this implant would not be compliant with the international guideline on implant survival (NICE guidelines: at 10 year follow up, 90% of all implants should still be in situ). Our objective was to establish the amount of liner wear in our first 200 MH implants. METHODS Our first 200 patients consecutively treated with Mallory Head prostheses were followed up to obtain a recent digital image. Follow up was complete for 181 (90.5%) of our 200 patients. Ten had died and nine were not able or willing to come for follow up. The mean duration of follow up was 8.3 years (range: 8–13). The 181 recent digital images were classified as either excessive wear or no excessive wear by two independent orthopedic surgeons. Next, liner wear was measured in the 2D frontal plane using PolyWare Pro/3D Digital Version Rev 5.1 software (Draftware Developers, Conway, USA). A threshold for excessive liner wear was set at 0.2mm/year, according to literature. RESULTS Using software for measuring PE wear, 46.7% of all patients had excessive UHMWPE wear (> 0.2mm/yr). There was no relation between the amount of wear and BMI, gender, component size or the acetabular inclination angle. Thirteen patients (6.5%) were revised. Nine of these revisions were for excessive liner wear or aseptic loosening (4.5%). For now, our series of cementless Mallory Head prostheses is compliant with the NICE guideline on implant survival. However, with the measured amount of wear we expect to see a significant increase in the number of revisions for liner wear in the near future. DISCUSSION Our clinical observation of premature UHMWPE wear proved correct. The measured amount of UHMWPE wear is consistent with the few other studies published on this subject. Although we present a retrospective study, limiting the strength of our results, we have included a large group of patients with acceptable loss to follow up. It is unclear if the observed wear will lead to a sharp increase in the number of revisions within the next few years. Possibly, future revisions will be complicated by loss of acetabular bone stock following the pathofysiological reaction to wear particles. Our results can probably be generalised for any district hospital.

Cerebral blood flow (CBF) autoregulation is a robust protective mechanism that maintains constant blood flow during changes in perfusion pressure. Although it is well known that major cardiovascular adaptations occur during normal pregnancies, the cerebral vascular adaptations that occur during pregnancy, especially in the setting of hypertensive pregnancies, are poorly understood. Hypertension is typically associated with normal autoregulatory function in the cerebral circulation, although the upper and lower limits of the autoregulatory curve are shifted to higher blood pressures. Previous studies in pregnant Sprague Dawley (SD) rats show that the cerebral autoregulatory curve is shifted to higher pressures compared to nonpregnant rats. The impact of preexisting hypertension on cerebral blood flow autoregulation has not been examined. The current study was performed to test the hypothesis that CBF autoregulation is impaired during pregnancy in the presence of underlying hypertension.


Ontological pluralism raises interesting questions about the objectivity and universality of arguments and argument forms. Bruno Latour proposes that Science, Politics, Law, Fiction, and other domains are distinct "modes of existence," each with its own set of "felicity" and "veridiction" conditions. If so, then are arguments and argument forms mode-dependent? I suggest that arguments and arguments forms can extend across multiple modes as long as they do not serve as infelicity conditions within those modes.


The oxidizing activity of cobaltic acetate in acetic acid is enhanced by strong organic or inorganic acids to such an extent that n-alkanes can be significantly oxidized at low temperature. The kinetics of cobalt(III) consumption in the presence of n-heptane as substrate and trifluoroacetic acid as activator under a nitrogen atmosphere has been studied: the process appears to be of the second order with respect to cobalt(III) and it is markedly retarded by cobalt(II). The products of the oxidation of n-alkanes by acid-activated cobaltic acetate in acetic acid are different according to whether oxygen is present or not. Acetic esters of alcohols are formed under nitrogen while ketones are mainly produced if oxygen is present; when trichloroacetic acid is used as activator under nitrogen, alkyl chlorides are the principal products. In each case, the products consist of a mixture of position isomers with a marked predominance of the isomer resulting from attack of the alkane on the second carbon atom of the chain. These results are consistent with a mechanism wherein the n-alkanes are attacked by cobalt(III) to afford reversibly cobalt(II) and an alkyl free radical. The selectivities observed are discussed.

The task of Bilingual Dictionary Induction (BDI) consists of generating translations for source language words which is important in the framework of machine translation (MT). The aim of the BUCC 2020 shared task is to perform BDI on various language pairs using comparable corpora. In this paper, we present our approach to the task of English-German and English-Russian language pairs. Our system relies on Bilingual Word Embeddings (BWEs) which are often used for BDI when only a small seed lexicon is available making them particularly effective in a low-resource setting. On the other hand, they perform well on high frequency words only. In order to improve the performance on rare words as well, we combine BWE based word similarity with word surface similarity methods, such as orthography In addition to the often used top-n translation method, we experiment with a margin based approach aiming for dynamic number of translations for each source word. We participate in both the open and closed tracks of the shared task and we show improved results of our method compared to simple vector similarity based approaches. Our system was ranked in the top-3 teams and achieved the best results for English-Russian.


laser and IOP Direct laser induced cell pits/pockmarks in the IOL and dislocation of the from a YAG capsulotomy is large. Infectious etiologies as well YAG capsulotomy. capsulotomy Abstract A 61 year old African American female underwent a Yttrium-Aluminum-Garnett (YAG) laser capsulotomy in the left eye. She presented with pain and blurry vision one day later and was found to have elevated intraocular pressure which persisted for a few days in spite of topical eye pressure lowering eye drops and oral acetazolamide. One week later the patient developed optic disc edema and a new visual field defect in the left eye. Local ocular and systemic evaluation was unremarkable for other causes of optic neuropathy, and the patient developed optic disc pallor several weeks later. The presumptive diagnosis was non-arteritic anterior ischemic optic neuropathy which has been previously reported after cataract surgery although occurrence after YAG capsulotomy is not known.


This paper takes advantage of HMM's statistic characters. With a little modification on HMM structure, it gets a mapping model from speech to image. After some pre-process, a HMM of certain object can be created according to training samples. Using this model , together with some necessary post-process work, it can synthesize smooth, realistic face speech animation independent of classification of language only with speech signal.

Genetic diversity, domestication and phenotypic plasticity of lima bean (Phaseolus lunatus L.) Lima bean (Phaseolus lunatus L.) is an important species of the Fabaceae family, which is distributed worldwide. The origin and domestication of the species is not fully understood due to the wide distribution and lack of wild accessions, as well as the loss of germplasm in many areas of its natural distribution, which indicates the importance of germplasm banks and the characterization of diversity and of domestication studies. The study of genetic diversity at the molecular level has been quite accomplished, the molecular markers od microsatellites (SSR), stand out. The lima bean has few studies using as tools the SSRs, not having specific loci for the species, which limits the knowledge about its genetics. Thus, the objective was to develop specific nuclear microsatellite loci (ncSSR) to study the genetic diversity, as well as the domestication process involving wild and domesticated accessions in different countries (Brazil, Mexico, Peru, Colombia and Argentina), by chloroplastids SSR markers (cpSSR), besides to study the phenotypic plasticity of Brazilian accessions. The phenotypic plasticity of 12 accessions from Brazil was estimated in four environments with different fertilizers (1 control without fertilization, 2 mineral fertilization with NPK, 3 organic fertilization with bovine manure, 4 – mineral [NPK] and organic fertilization [manure]). The design was completely randomized with three replicates. The evaluated traits were: Number of Days for Flowering (NDF), Number of Days for Maturation (NDM), Number of Pods per Plant (NVP), Number of Seeds per Plant (NSP), Pod Length (CV), Pod Width (LV), Number of Locules per Pod (NLV), and Weight of One Hundred Seeds (P100S). The analysis of variance was performed, the index of Phenotypic Plasticity (IPF) and the Pearson Correlation between the characters were estimated. Microsatellite markers were used for the determination of genetic diversity and structure, with five chloroplastid (cpSSR) and three nuclear loci (ncSSR) in 44 accessions of lima bean. There was phenotypic plasticity in the accessions of lima bean. All characters except for NDF and NSV presentated genotype x environment interaction significant for the four environments evaluated. NVP and NSP had the highest (0.82) and NDF the lowest (0.06) IPF, thus being the most and the least plastic, respectively, in the four environments. The highest positive correlation was observed between NVP x NSP, so that their values vary in the same direction. NVP and P100S had the highest negative correlation. The genetic diversity observed with nuclear and chloroplast microsatellite markers was greater in accessions from Mexico (cpSSR = 0.163; ncSSR = 0.15), followed by Brazil (cpSSR = 0.111; ncSSR = 0.00). At the variety level, wild accessions had lower diversity with cpSSR (0.16) and higher diversity with ncSSR (0.14) than domestic (cpSSR = 0.119; ncSSR = 0.02). High levels of variation and genetic differentiation were observed among countries, with 94% of the variation and Fst = 0.874, and between varieties, with 87% and Fst = 0.944 with cpSSR. With ncSSR, greater variation and differentiation occurred between accessions (61%, Fst = 0.771) and within varieties (80%, Fst = 0.788). These differences may be related to differences in the inheritance pattern of the markers. Chloroplast SSRs are more conserved and have maternal inheritance. Thus, accessions from the same country retain the same haplotypes, presenting low differentiation between them. The opposite occurs with nuclear SSR, which has a biparental inheritance and a higher percentage of mutation. Thus, a greater differentiation exists between the accessions, which is favored by the predominantly autogamous reproductive system. Brazilian domesticated accessions are genetically closest to the Mexican wild accessions, and may have resulted from the domestication of wild individuals from Mexico.


A system with a double multiplier is presented, it has been shown that this kind of system allows to increase the communication range. In the presented technology the system could work with a power of 1dB lower than standard system and this result could be more important in others technologies. Feasibility of antennas which are compliant with two ports chip is established. The double antenna present a worth matching in comparison with standard antenna, but its gain is more important.


Problem statement: Power consumption was one of the most challenging aspects to design low power wireless sensor nodes. The objectives of the study were to (i) Design low voltage, low power transmitters for wireless sensor nodes and (ii) Compare and analyze the performance of the transmitters. Approach: The transmitters employed direct digital modulation scheme to reduce the power consumption of the sensor nodes. Emphasis was placed on observing device reliability constraints at low power to maximize the life time of the wireless sensor nodes. Results: The Amplitude Shift Keying (ASK) transmitter consumed a power of 400.104 μw from the 1.2 V supply. The Frequency Shift Keying (FSK) and Phase Shift Keying (PSK) transmitters consumed 520 μw and 5.2 mw respectively at 2.4 GHz. The transmitters suitable for low voltage, low power wireless sensor nodes were designed and implemented in 120 nm CMOS technology Conclusion: The performances of the ASK, FSK and PSK transmitters were analyzed and were compared with the previously reported low power approaches operated in similar frequency ranges.

Pancytopenia is a common medical condition characterized by reduction in all the cellular elements of the peripheral blood lineages: leukocytes, platelets, and erythrocytes.[1] There are multiple causes of pancytopenia varying widely in children, ranging from transient marrow suppression to marrow in ltration by life threatening malignancy. It is relatively different in the developing countries from the developed ones. Peripheral Pancytopenia requires microscopic examination of a bone marrow biopsy and a marrow aspirate to assess overall cellularity and morphology. Although pancytopenia is a common clinical nding with extensive differential diagnosis, there is a relatively little discussion of this abnormality in literature and there is the lack of data on pancytopenia in pediatric age group, especially with regards to clinical and etiological ndings, in South-East Asia. This study has been undertaken to identify easily treatable and reversible causes of pancytopenia.


Here we present an English translation of the last chapter of the book Beiträge zur Archäologie Boliviens (Walter 1966), which describes the results of a major German expedition. In addition to this chapter, the book describes the expedition's excavations in Oruro, at the site Huancarani, and in Cochabamba, the sites Cliza-Chullpapata and Mizque-Lakatambo. In the introduction, Hermann Trimborn explains that one of the project's goals was to reveal that Bolivia's rich cultural diversity went beyond the Lake Titicaca Basin. The 1958 expedition had the support of the University Museum of Cochabamba, at the time headed by Dick E. Ibarra Grasso. It was led by Hans Dietrich Disselhoff and organized by Berlin's Museum für Völkerkunde. Disselhoff described Walter as an ethnologist and prehistorian, a man of few words, self-disciplined, and responsible. He was the only one on the team not afraid of heights so he was able to reach the sites Inca Machay and Pucara de Oroncota. He reportedly mapped Pucara de Oroncota and did all the drawings of the excavations and artifacts. This volume is a classic for German-speaking archaeologists working in Bolivia, but is not widely known in the US or Latin America, in part because German is not a working language of most Andean archaeologists. It was issued as a supplementary volume of the journal Baessler-Archiv, which was first published in 1911 and is available at https:// digi.evifa.de/. Walter's supplementary volume, however, is not yet available online and can be difficult to locate, even in university libraries. Furthermore, connections to better-known sites


This paper uses 1997-2005 LFS data to study the impact of immigration on natives' wages, and wage distribution. We present a theoretical model where we show that if capital is supplied at a price fixed on international markets, immigration will have on average a positive wage effect, as long as immigrants differ from natives in their skill composition. However, along the distribution of wages, some workers will lose, while others will gain We derive from this model estimating equations that we use for our empirical study. In accordance with theory, we find evidence of overall positive wage effects of immigration. Investigation of the effects of immigration along the distribution of wages of non-immigrant workers suggests that there are clear and significant differences. Natives in the middle of the wage distribution gain from immigration, while natives at the bottom of the distribution lose in terms of wages. Migrant Workers and the National Minimum Wage 2 In 2001, the last census year, 4.8m immigrants lived in the UK, which amounts to 8.47 percent of the total population, or 9.75 percent of the working age population. Since then, Britain has experienced a further increase in its foreign born population, and the share of foreign born in the total population in 2005 was 11.5 %. There are concerns about the effect that this increase in foreign born individuals may have on wages and employment of native workers. Most of the empirical literature on immigration for the US establishes only small employment-and wage effects (see e. although this view is not unanimous (see e.g. Borjas 2003). These findings for the US may not necessarily be transferable to the UK, as the skill structure of immigrants differs between the two countries. Recent work on the British labour market (Dustmann, Fabbri and Preston 2005) points to possible small negative employment effects, in particular for workers in medium skill categories, but no, or positive wage effects. In this paper, we provide new analysis of wage effects of immigration to Britain, using a wider framework of analysis and evaluation than in our earlier work, and concentrating on recent immigration to Britain. Furthermore, we will particularly focus on the effect of immigration on logs of native wages at different percentiles in the wage distribution. The usual underlying theoretical framework for analysis of immigration on wages and employment is a simple one output economy, with capital and two types of labour …


IntroductionThe United Kingdom National Health Service (the NHS) is radically restructuring its arrangements for planning, procuring, evaluating healthcare provision (i.e. ?commissioning?), devolving this responsibility to newly created Clinical Commissioning Groups (CCG?s), composed of local family physicians (GP?s). GP-led commissioning is a new practice. A Practice Research approach might assist the growth of local expertise, contribute acquired knowledge to the general practice of commissioning and stimulate the development of new theoretical and methodological approaches.Purpose and aimsTo engage with clinical commissioning groups (CCG?s), we aim to provide a preliminary conceptualisation of the problem situation; second, to develop preliminary ideas on a problem solving approach that can be adapted to the landscape of commissioning as it evolves; and, third, to inform our own ongoing programme of research and understanding. Methodological approachSynthesise model of intended research from recent literature. Explore multiple perspectives influencing mental models of the problem situation. FindingsThe three forms of perspective explored illustrate social and political considerations which interfere with the rationality of the new practice.Conclusion: Value and Implications We offer a model of the ?physiology? of practice research applied to commissioning, showing how its interacting parts function as an organic whole.We make no recommendations on specific healthcare commissioning objectives but we have shown how healthcare commissioning as a problem situation can be described from multiple perspectives and we suggest that the discipline of taking these perspectives on the commissioning situation has the capacity to enrich understanding, comprehensive diagnosis and accurate prognosis for the health economy concerned. We hope to develop this theme in our future projects.


Abstract. The Amazon Basin is frequently influenced by transatlantic transport of African dust plumes during its wet season (January–April), which not only interrupts the near-pristine atmospheric condition in that season, but also
provides nutrient inputs to the Amazon rainforest upon deposition. In this
study, we use the chemical transport model GEOS-Chem to investigate the
impact of the export of African mineral dust to the Amazon Basin during the
period of 2013–2017, constrained by multiple datasets obtained from the
AErosol RObotic NETwork (AERONET), MODIS, as well as the Cayenne site and the Amazon Tall Tower Observatory (ATTO) site in the Amazon Basin. With an optimized particle mass size distribution (PMSD) of dust aerosols, the model captures observed aerosol optical depth (AOD) well in terms of both the mean value and the decline rate of the logarithm of AOD over the Atlantic Ocean along the transport path (AOaTP), implying consistency with the observed export efficiency of African dust along the transatlantic transport. With an annual emission of 0.73±0.12 Pg yr−1, African dust entering the Amazon Basin during the wet season accounts for 40±4.5 % (up to 70 %) of surface aerosol mass concentrations over the basin. Observed dust peaks over the Amazon Basin are generally associated with relatively higher African dust emissions (including the Sahara and the Sahel) and longer lifetimes of dust along the transatlantic transport, i.e., higher export efficiency of African dust across the Atlantic Ocean. The frequency of dust events during the wet season is around 18 % when averaged over the Amazon Basin, with maxima of over 60 % at the northeastern coast. During the dust events, AOD over most of the Amazon Basin is dominated by dust. Based on dust deposition, we further estimate annual inputs of 52±8.7, 0.97±0.16, and 21±3.6 mg m−2 yr−1 for iron, phosphorus, and magnesium, respectively, into the Amazon rainforest, which may to some extent compensate for the hydrologic losses of nutrients in the forest ecosystem.

Injection locking is one of the few approaches available for simultaneously controlling the far field emission and spectral characteristics of high power laser diode arrays1–4. Previous investigators have obtained narrow far field emission lobes with nearly single mode, narrow line operation. Steering of the far field emission angle is possible by varying the injection frequency or array bias2–4.


Hereby, we present a rare case of 22 year-old pregnant woman with a suspicious adnexal mass coexisting multiple nodules on ovary, peritoneum and omentum diagnosed as disseminated peritoneal leiomyomatosis.


Examination of the rapidly increasing body of OD literature reveals that much of its research is redundant and without refinement or validation, that the term "Organizational Development" itself remains scientifically undefined and hence primarily a convenient label for a variety of activities, and that the OD literature as a whole is more autobiographical than organizational in focus and scope. Work toward resolution of these three problems, the author suggests, would help the practice of OD base itself on a more mature and usable set of principles and procedures for organizational change. The author also questions the adequacy and utility of the traditional dichotomy between organizational process and structure evident in the literature and discusses a reconceptualization of organizational structure that permits clarification of key issues in the practice and theory of organizational change.


Synopsis: In the 2nd and 3rd Reports (Tetsu-to-Hagane, 1958, No. 8, p. 872~880, and No. 11, p. 1259~ 1265) the authors made some observations and experiments with the large ingots which revealed several phenomena concerning the vertical segregation occurred in the melt of ingot core. Combining these new findings with some of the known primary causes for segregation, an unified and systematic explanation for the mechanism of formation of the three major segregations, i. e. inverse V, V and negative segregation, can be derived. Assuming that the convection and chemical changes in the melt of solidifying, core, Soreteffect at the liquid-solid interface, dilution (diffusion) of concentrated elements into the mother-liquor, etc. have no first-order effect upon the formation of macro-segregation, then the concentrating action at the liquid-solid interface and upward transfer in the solidifying melt


(1) it is his definitive statement of ecologicalevolutionary theory (hereafter EET); (2) it provides several empirical applications of the theory; (3) it is a critique of American sociology; and (4) it is a slice of intellectual autobiography. Many sociologists, including this reviewer, owe a debt to Lenski for his inspiration to study long-term social change. His work is a major reason evolutionary theory is "alive and kicking" (cf. Chirot 2005). It is also an effort to help sociology remain true to its name: the study of societies.


The making of culture in South Africa through different but linked forms and genres focuses on the medium of radio, and the 'emergent genre' of Zulu serial radio drama. Using Benedict Anderson's notion of 'socioscape' a link is drawn between the wide sweep of historical events and the production of culture. Beginning with the case of the musical, uMabatha [Macbeth], its performance history, and its links with serial radio drama in Zulu, this article focuses on the ways in which this, in turn was linked to the 'performance' of African football commentary on radio, and points to the national resonances that the act, and art, of commentating built up for both announcers and listeners. Finally, three representative radio serial plays from the 1970s are examined in relation to the ways in which they engaged with the social and political realities of the time. Through the multi-accentual nature of language and the polysemic nature of the plays themselves these plays might appear to endorse or, at least, acquiesce in the dominant apartheid ideology of the era, yet at the same time they offered resistant alternatives to it.


The competitive bare-hand fighting is regarded as a new emerging national traditional sports item. In this context the related studies and research about it in the level of theory are rarely seen in China, which is outdated from the rapid development of the bare-hand fighting techniques. Few existed studies are criticized for the lack of the theoretical research depth, for instance, emphasizing on the simple data statistics of the techniques or the imitation of the oversea boxing techniques. In addition when compared with other sports categories the theoretical studies on the contest sports items are relatively lower. Based on the great number of the documentary analysis and practical video statistics analysis, in the view of the attack-defend characteristics of the contest sports times, this research proposes a new classification methods depending on three different standards. Through the competition statistics and practical observation, this study analyzes the characteristics of the application of the bare-hand fighting techniques and its sequent effects, and reveals the principles of it in order to provide the scientific evidence for the scientific and pertinent development of the competitive bare-hand fighting.


Abstract: Globally, coal-fired power plants are the largest industrial source of carbon dioxide (CO 2 ). CO 2 emissions from flue gas have potential for direct mineralization with electrostatic precipitator fly ash particles in the field. Demonstration scale accelerated mineral carbonation (AMC) studies were conducted at the Jim Bridger Power Plant, a large coal fired power plant located in Wyoming, USA. AMC produces kinetically rapid conditions for increased rates of mineralization of CO 2 , sulfur dioxide (SO 2 ) and mercury (Hg) on fly ash particles. Control and AMC reacted fly ash particles were investigated for: change in carbon (expressed as CaCO 3 ), sulfur (expressed as SO 42− ), and mercury (Hg) contents; topology and surface chemical composition by scanning electron microscope/energy dispersive X-ray spectroscopy analysis; chemical distribution of trace elements; and aqueous mineral solubility by the toxicity characteristic leaching procedure. Results of the AMC process show an increase in C, S, and Hg on AMC fly ash particles suggesting that multiple pollutants from flue gas can be removed through this direct mineral carbonation process. Results also suggest that the AMC process shifts soluble trace elements in fly ash to less leachable mineral fractions. The results of this study can provide insight into potential successful field implementation of AMC.


The book makes its most decisive contribution to the study of nineteenth-century Mexico in chapter 3, by reconstructing a story obscured by the nationalist narrative of the liberal republic's triumph over Maximilian, the French, and their conservative supporters. Richmond finds that, contrary to its reputation for weakness and ineptitude, the government of Maximilian realized tangible if short-lived improvements in the Yucata ́n. In this account, Maximilian, his wife Carlota, and governor Ilarregui take center stage as protagonists in an epic historical drama. Moreover, its short length and narrative approach make the book suitable for both advanced undergraduate courses and graduate courses.


We give a dynamical description, in terms of a Weil-type zeta function, to the holomorphic torsion with coefficients for certain compact Hermitian locally symmetric manifolds, whose connected group G of isometries of the universal cover has only one conjugacy class of cuspidal maximal parabolic subgroup and also satisfies a technical Ansatz relative to the given coefficients. The two senior authors are indebted to their junior colleague, Jan Frahm, for his laborious work shedding light on the scope of the validity of the Ansatz, and for writing up the attached Appendix. The results therein show that for real rank one groups G the Ansatz is satisfied with respect to any coefficients, for some rank two groups G it is satisfied with respect to certain coefficients, and also that there are groups G which do not obey the Ansatz.


Rauhora sarax akensis is well known as Sarawak Rasbora that belongs to family Cvprinidae. This fish is significant for ornamental purposes and as molecular tools to study the phylogenetic relationship among the other Rasbora spp. In order to determine the phylogenetic relationship, mitochondrial genome is being targeted for analysis. In this study, our purpose is to isolate and characterize a partial fragment of mitochondrial genome (tRNA-GIn'-tRNA- /. vs') of R. saraxnkensis. The collection of R. sarawakensis was conducted at Matang Wildlife Park and acclimatized at 26 °C, 12 hours dark and light photoperiod. DNA extraction was conducted using CTAB method and the fragment of mitochondrial genome was amplified through PCR. Four pairs of gene specific primer were designed for PCR amplification of this fragment based on the conserved sequences from multiple alignment of three selected freshwater fishes. PCR amplification had generated four fragments of PCR amplicons in which their length are close to the expected size during primer design. The PCR products were purified using QlAquick PCR
Purification Kit (Qiagen, Germany) and was analyzed through AGE. Subsequently, the sample was sent to the First
BASE Company for sequencing. The E-value and blast identity obtained for all of the four fragments are 0.0 and more than 80% respectively. Sequence that is obtained was aligned to other previously isolated fragment to generate complete mitochondrial fragment for R. sarawakensis. Phylogenetic analysis revealed high bootstrap support between R. sarmrcrkensis and other closely related Rasbora spp. This study serves as a platform for further understanding in the population genetic of Rauhora spp. that might be useful in future conservation effort.


Background A questionnaire-based survey was conducted to determine the preanesthetic evaluation (PAE) practices among the members of the Indian Society of Neuroanesthesiology and Critical Care (ISNACC). The survey aimed to assess the current clinical practice of PAE and optimization of neurosurgical patients in India.
 Methods An online questionnaire was designed by the working group of ISNACC and circulated among its active members. Response to individual questions was considered significant if 50% or more respondents concurred. The survey questions to which less than 50% of respondents concurred were identified as inconclusive results.
 Results Out of 438 active ISNACC members, 218 responded. Responses were obtained from various parts of the country. The majority of participants were practicing neuroanesthesiology. Questions asked were regarding clinical assessment, preoperative optimization, prognostication, and airway management in neurosurgery. More than 50% of practitioners acceded to most of the questions; however, the percentage of responses varied across different questions (50–100%). The questions related to preoperative duplex scanning in chronically immobilized patients, preoperative cognitive testing, and risk stratification during neurosurgical procedures received an inconclusive response (< 50%).
 Conclusion The survey highlights the variable PAE practices perused by ISNACC members across the country. A guideline for uniform PAE practices may help to enhance research and improve perioperative care.


THE ASSOCIATION between higher plasma insulin and higher blood pressure levels is now recognized as a fundamental relationship. Higher plasma insulin values have been described in lean patients with hypertension, 1,2 in borderline hypertension, 3 in subjects with only an office "white coat" blood pressure elevation, 4 and even in normotensive individuals with higher blood pressure readings. 5 The report by Jiang et al 6 in this issue of theArchivesshows that this relationship has its roots in early life; a positive correlation between blood pressure and plasma insulin values is already present at ages 5 to 8 years and 9 to 12 years, and the association is very strong again at age 18 to 26 years. The fact that the correlation looses its strength during puberty does not detract from the importance of the relationship; during that period, the rapid rate of growth coupled with the steep increase


This report presents a VTT roadmap on ICT for environmental sustainability, based on the assessments and evaluations made by VTT technology experts. We adopt a broad and systemic view to the issue; in other words, we believe that ICT's effectiveness depends on mutual understanding and changing the system level activities, i.e. the complex web of behaviour of people, institutions, organisations and political jurisdictions, like nation-states. We use the term ICT for environmental sustainability or environmentally sustainable ICT, instead of green ICT, and defined it as: Use of ICT for optimising societal activities in order to improve environmental sustainability. The roadmap is divided into three themes. Empowering people means using ICT to raise people's awareness of the environmental impact of their actions and to channel their behaviour in a more environmentally-friendly direction. Extending natural resources involves reducing the use of diverse environmentally unsustainable re-sources through ICT-based solutions. Optimising systems refers to minimising the environmental load of diverse systems by optimising their operation. As a synthesis, we identified four focal topics within the roadmap themes that are most promising for further investigation. These are: 1) environmentally sustainable consumption, 2) smart energy and buildings, 3) lifecycle efficient production, and 4) optimised and adaptive networks.


Composites made of fiber-reinforced polymer (FRP) have gained popularity as new high-performance material for concrete buildings in now days. The advantages of FRP composites include high strength, lightweight, and corrosion resistance. This paper's primary objective is to assess the affect of FRP strips on the strengthening and repair of plain and reinforced concrete slabs. under the monotonic, impact, and repeated loading. According to studies' observations, applying FRP strips to RC slabs significantly affects the final load and deflection. The number and positioning of FRP sheets improve the performance of slabs. The failure load magnitude of strengthened slabs would increase as slab thickness, concrete compressive strength, and sheet thickness increase. The ultimate load capacity was increased by (27-52%), depending on the FRP strengthening strategy used. GFRP sheets could be employed for improving or enhancing the impact strength of concrete structures. Externally attached GFRP sheets gave good resistance for reinforced concrete slabs against typical explosive blast.


As a consequence of QCD, a broken supersymmetry exists between baryons and mesons. The supersymmetry is badly broken by effects of mass and spin differences between a diquark in a baryon and an antiquark in a meson. However, if one takes these differences into account, one can obtain fairly good predictions for the masses of some baryons from the masses of their meson supersymmetric partners.


Herein, the ruthenium-catalyzed regioselective sp2(C-H) monoalkenylation of N-arylpyridones has been demonstrated, where the pyridone was utilized as a weakly coordinating directing group. Importantly, the current methodology has been effectively applied to the synthesis of many drug analogues such as pirfenidone, naproxen, ibuprofen, geraniol, umbelliferone, pregnenolone, and estrone. This methodology tolerates a wide range of functional groups and yields up to 93% yield. A six-membered ruthenium complex was also detected by HRMS.

History is very essential in design process because to create progress. It requires an understanding of what has already been accomplished. This paper is a learning outcome of history of product design courses in product design of Pelita Harapan University.  Art Nouveau is a style that aimed to introduce new art during the 1880s post-industrial revolution in Paris. With its obsession with novelty, Art Nouveau incorporates elements from a variety of cultures, including Japan, Moorish art, nature, and numerous material explorations. Emile Galle, one of the Art Nouveau figures in Paris. He explored and invented numerous new glass techniques such as wheel cutting, acid etching (frosted glass), and glass casing layering. The journal uses of ATUMICS, a method for deriving structured inspiration from artifacts that incorporate technique, utility, material, icon, concept, and shape. The novelty of this journal stems from the combination of two artifacts: the cameo glass technique and an Indonesian icon, the national monument and the rafflesia Arnoldi flower, where the interaction of the two resulted in product design works in fashion accessories. This process demonstrates that the elements that play important role when two artefacts are interacting using the ATUMICS method are technique, relational icon, and concept. Whereas the reciprocal relationship between artifacts on a symbolic level inspires each other in all three dimensions.

The main objective of this study is to improve the soft clayey sub-grade soil by mixing cheap and locally available materials like lime and rice husk ash with it. The present investigation has been carried out with these materials mixed individually and also in combination with locally available clayey soil in different proportions at corresponding Optimum Moisture Content (OMC) and 2% above optimum moisture content (OMC+2%). The laboratory test results show marked improvement of strength of soil on addition of admixtures in terms of both California Bearing Ratio (CBR) and Unconfined Compressive Strength (UCS). Based on the laboratory test results a correlation has been developed in the form of California Bearing Ratio (CBR) considering it as a function of different soil parameters by the multiple linear regression analysis.


Settlement, endemic Violence and wild Space Remanence in West Africa. «W» of Niger no man's land. The existence of no man's lands created and maintained by endemic violence is one of the characteristics of West African settlements. The case studied here is that of the region defined by the Tapoa, Alibori and Niger rivers, which was brought under the protection of the colonial authorities and named Park «W» of Niger between 1926 and 1954. It is necessary to understand the status of these areas in order to better manage the periphery of the Park and this has led us to analyse certain aspects of the geopolitics of the eastern Niger bend area and their effects on the settlement of the land (Songhai, Borgou, Gurma, Zerma and Fulani areas). The cartography proposed illustrates the relationship between violence, depopulation and the renaissance of the wilderness.

This system is characterized by the following features: high integrity solid body cask with dual lid; 80 metric ton rail cask suitable for a 4-axle flat bed transporter; uncomplicated design and dry handling permit efficient cask loading and unloading operations; and a convertible capacity design permits flexible and efficient packaging for multi-site utilization and lower overall costs.


This research is conducted to determine the behavior and motivation of foreign students traveling in Bali, especially those studying at Udayana University. Samples taken are foreign students who join short semesters in the GoBali International Program, IBSN and BIPAS. This research is important since foreign student market is being underestimated because it is considered to have low purchasing power, however tourism stakeholders seem to forget that they spend more time in the place where they study. By staying longer in Bali, there are two benefits to be gained. The first benefit is to support the local economy, because these foreign students stay for 20 weeks, it means they will rent a place to live, transport and spend their money. The second benefit is that foreign students will most likely explore places that hold the potential to become tourist attractions in the future. Indirectly, this foreign student will help stakeholders in tourism in identifying appropriate places to be made as tourist destinations. The methodology used to obtain data is preceded by a focus group to identify what factors need to be explored more in relation to their behavior and motivations in Bali. Then, after the factors are obtained, data collection through questionnaires is conducted to then use factor analysis, cluster analysis and compile the highest average values based on cluster groups, so that answers will be obtained on the degree of interests and behavioral tendencies of foreign students traveling in Bali.Keywords: foreign students, behavior, motivation, travel, short semester, udayana.


Simple Summary The extraction of oils from olives usually results in large quantities of olive cake meal (OCM), which has a high nutritional value. The OCM is used successfully in livestock and poultry feeding, but due to the high fiber content, alternative methods of treating OCM must be considered. To increase the efficiency of OCM in broiler chickens' diet, it can be mixed with suitable microorganisms with beneficial effects. Hence, the current study investigated the influence of OCM and Bacillus licheniformis (BL) on the growth, nutrient utilization, blood chemistry, and muscle fatty acid profile of broilers. Birds were divided into six experimental groups (control, OCM (2%), OCM (4%), BL, OCM (2%)/BL, and OCM (4%)/BL groups). The results revealed that the inclusion of BL with OCM diets improved the fat utilization and, accordingly, increased the growth, nutrient utilization, and antioxidative response in broilers. Abstract Olive cake meal (OCM) is characterized by its high nutritional value and is used as an alternative source of protein and fats in poultry diets. However, due to the high percentage of fiber in OCM, beneficial bacteria cells are used to improve the digestion rates. Therefore, the influence of OCM and Bacillus licheniformis (BL) on the growth, nutrient utilization, blood chemistry, and muscle fatty acid profile of broilers was exclusively examined in this study. Three hundred and sixty birds were randomly divided into six experimental groups (6 replicates/10 birds each): Control, OCM (2%), OCM (4%), BL, OCM (2%)/BL, and OCM (4%)/BL groups. Although feed intake was not meaningfully influenced by dietary treatments, weight gain was enhanced and feed conversion ratio was reduced (p < 0.05). The abdominal fat was lowered in broilers fed OCM (2%), OCM (4%), OCM (2%)/BL, and OCM (4%)/BL diets without a difference to those fed BL only (p < 0.05). Interestingly, blood total protein, albumin, Newcastle disease (ND) titer, and high-density lipoprotein (HDL) cholesterol were significantly increased, while total cholesterol was decreased by the mixture of OCM and BL (p < 0.05). Muscle oleic and linoleic acids, as well as vitamin E, increased significantly in broilers fed both OCM (4%) and BL, while linolenic acid increased in all groups except those fed BL and control diets (p < 0.05). Liver malondialdehyde (MDA) was decreased by feeding BL or both OCM at 2% or 4% and BL (p < 0.05). In conclusion, the inclusion of BL to OCM diets resulted in improved fat utilization and, accordingly, enhanced growth, nutrient utilization, and antioxidative response in broilers. Based on the obtained results, it is recommended to use BL to improve the nutritional value of OCM and to increase the feed utilization of OCM by broilers.


At JAEA, a test blanket module (TBM) with a water-cooled solid breeder is being developed. This paper presents recent achievements of research activities for the TBM, particularly addressing the pebble bed of the tritium breeder materials and tritium behaviour. For the breeder material, the chemical stability of Li2TiO3 was improved using Li2O additives. To analyse the pebble bed behaviour, thermomechanical properties of the Li2TiO3 pebble bed were assessed experimentally. To verify the pebble bed's nuclear properties, the activation foil method was proposed and a preliminary experiment was conducted. To reduce the tritium permeation, the chemical densified coating method was developed and the coating was attached to F82H steel. For tritium behaviour, the tritium recovery system was modified in consideration of the design change of the TBM.


notes to this edition, however, Goldgar presents a learned case for the merits of the Journey—"Fielding's richest and most extensive piece of prose fiction outside of the three novels and Jonathan Wild" (p. xxxvi). Goldgar' s notes reveal the multi-layered and densely allusive texture of the Journey, which weaves together an array of references to contemporary events and people with stories derived from both myth and history. The historian Gibbon particularly praised the long narrative of Julian the Apostate, whom the Spirit traveller meets in Elysium, as "the history of the human nature" (p. 50n6). Indeed, Fielding in these chapters comes close to creating the kind of historical fiction later perfected by Scott and Thackeray. Repeatedly reincarnated into the mortal world, Julian acts out various fictional lives on a stage set with real historical events and personalities. Goldgar maintains as well that the Journey is less jumbled and inconsistent than often claimed: in keeping with a repeated theme in volume 1 , and with the central concern of Jonathan Wild, this narrative returns frequently to the moral and political issue of "false greatness" and "the conflict between the lust for power and the claims of virtue" (p. xxviii). Goldgar is right to make a case for the significance of Fielding's neglected Journey. Is it necessary, however, to insist on the formal and thematic continuity of this work? In our time, re-educated by the tradition of Bakhtin, we are again in a position to recognize the value of a work that is deliberately eclectic and discontinuous, and that aims for variety for variety's sake. In fact, the theme of false greatness, though important to Fielding's outlook, is never quite "the overriding theme" (p. xxv) of the Journey. Even Julian's account of his various earthly lives shifts abruptly between stories of kings and beggars, statesmen and common soldiers, fools, fiddlers, aldermen, and poets. This quite pointed juxtaposition of the haughty and the vulgar, the grave and absurd, characterizes much of this work. In chapter 6, for example, Fielding combines "the Spindle of Necessity," an image in Plato's Republic, with a Lottery Wheel, as might be found at an eighteenthcentury country fair. The judge at the gate of Elysium, Minos, is a rough true-blue yeoman who admits or rejects applicants with a slap on the back or a kick in the A—. This is, in brief, a classically carnivalesque work. In the tradition of Menippean satire, it aims above all to embrace the diversity of human life, and to show the ultimate proximity of the grave and the ludicrous, the pompous and the debased. In this diversity, it mirrors the wrenching contrasts of triumph and tragedy in Fielding's own life in the 1740s. It also reflects the more organized play of high and low, of the grave and the profane, that Fielding harnessed so effectively in his great achievements as a novelist.


Being satisfied with the job is significant for organizations. Certain human resource management practices account for job satisfaction and improved performance. The researcher being one of the faculty members of a Higher Education Institution (HEI), felt the need to study on what greatly affects work performance of faculty members in an HEI. The participants of the study were all faculty members, deans and students of the Teacher Education Institutions in Bohol. There was no sampling technique applied since all of them were included in the study. It employed the descriptive-correlation method in gathering the data by employing standardized questionnaires. To determine the perception of the respondents in terms human resource management practices and the level of job satisfaction, the weighted formula was employed. For the teaching performance of the faculty members, the arithmetic mean was used. To determine the relationship between HRM practices and job satisfaction to teaching performance, Pearson Product – Moment Coefficient of Correlation was used while to obtain the data for the difference in the performance of faculty members when grouped according to the raters, One-Way Analysis of Variance (ANOVA) was used. Findings revealed that the faculty members perceived highly the existing human resource management practices in their workplace. The participants developed a high perception with these aspects of human resource management practices. In terms of job satisfaction, the participants perceived a high level of job satisfaction. They found satisfaction with the meaningfulness of the job, social benefits and support from the administrators. The mean of work performance of the faculty members is very satisfactory and there is no difference in the mean of work performance of faculty members as perceived by the deans and students. The result further revealed that there is a significant relationship of human resource management practices, job satisfaction and teaching performance as indicated by the critical value. The study concludes that faculty members with satisfactory performance are driven by a sound human resource practice and satisfaction with their job as teachers. The support from the human resource management department and other administrators results in better teaching performance.

To the Editor: The very interesting article of Jacobs et al. [8] on Neuropsychological characteristics of dementia in Parkinson's disease (PD) suggests several ideas. A preclinical phase of parkinsonian dementia can be identified, and this preclinical phase presents a specific neuropsychological pattern that can be distinguished from the pattern seen in Alzheimer's disease. Verbal fluency represents the type of cognitive performance that can best be correlated with subsequent development of dementia, and poor performance on these tests would reflect an executive dysfunction due to an involvement of the frontal-subcortical circuits.

On the basis of our own results, an early frontal dysfunction can be considered the best predictive factor for the development of dementia in PD. [2] In particular, in an otherwise unselected sample of parkinsonian patients, we found that four different types of relationships can be observed between a frontal syndrome, dementia and PD: (1) no cognitive abnormalities are revealed by neuropsychological evaluation; (2) the frontal symptomatology is associated with a more generalized cognitive impairment; (3) signs of frontal dysfunction constitute the sole cognitive alteration that can be noted; and (4) the neuropsychological examination reveals abnormal cognitive functions that cannot be attributed to a frontal dysfunction.

The first pattern can be …


Background: Welfare technology is a concept that appears as one of the answers to how to meet the need for care in growing older populations. Although technology has been used for decades in eldercare, it is under-problematized and there is a lack of knowledge about how effective it really is.

Objectives: This paper reviews the usage of technologies in eldercare and describes determinants of successful implementation of technologies in eldercare. The review aims to summarize and critically evaluate important aspects of technology usage in eldercare.

Method: A narrative review method was selected for analysis of the literature. Through applying a narrative perspective to review the literature on technologies in eldercare, a broad understanding is gained of the contextual factors and main key success factors of implementing technologies in eldercare.

Result: The review yield 71 publications related to technologies in eldercare. Seven themes were identified: (1) curriculum of technologies in eldercare; (2) on technologies; (3) evaluation models; (4) key success factors; (5) perception – care personnel; (6) perception – older users; and (7) controversies and dilemmas

Discussion and Implications: The result of the review shows that technologies in eldercare are promoted to enable more seamless, efficient, patient-centered and safe care, however technologies might be contributing to making eldercare more fragmented, time-consuming, technology-centered and risky. Technologies in eldercare are only as successful and suitable as organizational culture, infrastructure and management practice allow them to be.


We demonstrate evidence of selective laser-induced desorption of ground state Br(2P3/2) and spin–orbit excited state Br(2P1/2) atoms from KBr single crystals following 6.4 eV irradiation. Laser excitation tuned selectively to a surface resonance below the first bulk absorption band excites surface states preferentially leading to surface specific reactions while inducing relatively insignificant bulk reaction. The experimental results are supported by embedded cluster ab initio calculations that indicate a reduced surface exciton energy compared to that of the bulk exciton with a slight further reduction for steps and kink sites. Low fluence irradiation of cleaved KBr crystals, near the calculated surface exciton energy of 6.2 eV, produces hyperthermal Br(2P3/2) emission without a significant thermal or Br(2P1/2) component. The hyperthermal emission is shown theoretically to be characteristic of surface induced reaction of exciton decomposition while thermal emission is attributed to bulk photoreaction.


In today's world, technology has assumed an indispensable role in everyday life. However, though developments in the Internet of Things (IoT) have laid a foundation for achieving different educational purposes, IoT is not being employed to its full potential. A separate issue is that the topic of geometry has been neglected or received only limited attention in schools, particularly in the early years. Moreover, as geometry is of paramount importance, the idea of teaching geometry in early childhood should be investigated. This paper proposes an IoT-based approach for teaching basic geometric shapes to children aged 5 to 6. Specifically, five nodes were designed to act as the vertices of shapes. In addition, educational videos comprising three sections —identification, recognition, and recollection — were provided. Using a sample of 35 boys the proposed solution was assessed in terms of its effect on learning outcomes and the learning process using pre-test, simultaneous test, and post-tests. The findings revealed a noticeable improvement in learning outcomes. Furthermore, the proposed approach made learning enjoyable, which, compared to the traditional approach toward learning geometric shapes, is considered an improvement.


From their outset, the U.S. wars in Afghanistan and Iraq have generated a significant body of literature. Given the length and vicissitudes of those two conflicts, much of the writing on the topics is highly politicized and intimately connected to very specific moments in time. Such works are excellent at capturing debates and sentiments surrounding particular issues or periods, but often lack the perspective and conceptual depth one might wish for when trying to develop a broader sense of the conflicts and their relationship to one another. As the United States has worked to extricate itself from both conflicts over the last few years it is becoming possible to develop more detached and ultimately more compelling analyses of these latest episodes of U.S. struggles in the Middle East. Indeed, Understanding the U.S.Wars in Iraq andAfghanistan, edited by Beth Bailey andRichard Immerman, is an excellent early effort in this regard. The book includes thirteen essays organized into four somewhat predictable though appropriate sections: "The Wars and Their Origins"; "The Possibilities and Limits of American Military and Diplomatic Strategy"; "Waging and the Wages of War"; and "Lessons and Legacies." These follow a well-crafted introduction that recounts the events of the morning of 11 September 2001 before tackling some of the deeper conceptual issues entangled in the Bush administration's decision to launch a "global war on terror" in response. It is not possible to discuss each of the essays in a review of this length, so let me note that in totality the essays offer a good sense of these conflicts at multiple levels. Some of the authors traverse expected ground, such as the uses of intelligence, changes inmilitary strategy, opposition to the war, the combatants' experiences, and the role of the media. Others till fresher soil, such as the role of human rights in American discourse and policy, the integration of the wars into popular culture, and how veterans have adjusted after their experiences in war. The essay authors treat their subjects with care and nuance, which is not always the case when tackling conflicts that have become so divisive over time. All of its strengths aside, the book does have its shortcomings. Some of these, such as references to the continuing search for Taliban leader Mullah Mohammed Omar (60) when we now know he died in 2013, are quite minor and can be attributed to writing about events that have not yet reached their full conclusion. There is also some unevenness in tone and copyediting across the essays. Finally, while not necessarily a shortcoming,


It is visualized that Ontologies and Semantic Web technologies will influence the next generation of E-learning environment. Ontology provides flexible educational platform architecture for E-learning environment. The success of the Semantic Web depends on the procreation of ontologies. In general, Ontology based Learning supports the construction of ontologies by an ontology engineer. It takes over the ability to act in a genuinely intelligent manner by assessing the learners initially and providing personalized suggestions to the learners indicating their strengths and weaknesses. This ontology learning framework proceeds through ontology importing, extracting, pruning, refinement, and evaluating giving the ontology engineer a wealth of coordinated tools for ontology modeling This tool has been developed with the view of providing software based training to potential engineers and educating them. We introduce our ontology model and propose an effective method for enhancing learning effect of students through construction of subject ontology. This paper focuses on the development of ontologybased E-learning support system which allows learners to build dynamic learning paths. We also present an approach for developing a Semantic Web-based intelligent E-learning support system, which focus on the Web Ontology Language RDF and OWL. Additionally an automated and an intelligent e-learning service system have been developed.


The cyclo-converter is employing thyristors which are naturally commutated. The circuit is a combination of a positive and a negative phase-controlled rectifier. There are two types: the envelope cyclo-converter and the sinusoidally pulse width modulated. Here we will examine the envelope cyclo-converter. Cyclo-converters are becoming obsolete and their use seems to be limited to very high power at very low-frequency applications. The application of the switching function technique is applied in this short chapter to derive the output voltage of the envelope cyclo-converter for a resistive load. Further development of the technique for the operation of the circuit with inductive load and its application to the phase controlled cyclo-converter is left to the interested reader.


The feasibility of zero-power control in flux-path control magnetic suspension is discussed. In the flux-path control magnetic suspension system, ferromagnetic control plates are inserted between a permanent magnet (magnetic source) and a floator and moved to vary the flux from the magnetic source to the floator. The zero-power control has been applied in active magnetic suspension with a DC electromagnet. In the zero-power controlled system, the control current was kept virtually zero in the steady states. The applicability of the zero-power control to the flux-path control magnetic suspension is discussed in this paper. The conditions required to achieve the zero-power control is presented in an analytical form. Experiments are carried in a fabricated apparatus to certify the theoretical predictions.


Scanning electron microscopic examination of the valves of Anomia simplex larvae and postlarvae provides details of bilateral asymmetry in shell morphology and microstructure. Central provincular denticles and larger anterior and posterior hinge teeth develop in both valves. The umbo of the left valve becomes increasingly prominent with larval development, whereas no umbo is evident in the right valve. Thus, right and left valves of the prodissoconch differ markedly in height.In the left valve of the dissoconch, union of antero- and posterodorsal shell margins above the hinge causes lateral, exterior displacement of the umbo. The internal ligament extends ventrally to the right valve. Thin antero- and posterodorsal shell margins of the right valve extend centrally against the substrate and eventually unite exterior to the ligament. An increasingly larger byssal foramen, with a flexible, organic covering, is formed in the right valve.The outer layer of the left valve of the dissoconch is foliated calcite, ...


SUMMARY: Radioactively-labeled flavor compounds are added to a food system prior to reduced-pressure distillation. The example used is benzaldehyde, which in the distillate is converted to its corresponding 2,4-dinitrophenylhydrazone. Separation of the labeled hydrazone from other material present is accomplished by thin-layer chromatography. Recovered material is quantitated using ultraviolet spectroscopy. Employing isotope monitoring data, the native aldehyde is calculated via isotope dilution. The method is adaptable to flavor compounds of sufficient volatility to be recovered under 5 mm Hg and 65°C, and which are stable or can be converted to a stable form for purification. The potential for quantitation of several components during an experiment is briefly discussed.


Real estate transactions have been one of the most shadowed sectors of the national economy. The COVID-19 pandemic and the quarantine measures introduced in 2020 to prevent its spreading have led to a sharp increase in the shadowing of the real estate sector, thus reversing the positive trend of the previous years. The study aims at finding ways to de-shadow the real estate sector and substantiating them. Changes in the level of shadowing relations in the real estate sector in 2020 are analyzed. It is found out that the quarantine restrictions introduced in 2020 had though short-term but major negative impact on activities in the real estate market, thus increasing the shadowing of the real estate transactions sector. Emphasis is placed on letting residential real estate as one of the most shadowed segments of the real estate sector. Gaps in the de-shadowing measures in the real estate sector in recent years are highlighted and critically assessed, in particular: Bill № 3618 "On Real Estate Activities in Ukraine"; Bill № 3928-1 "On Amendments to the Tax Code of Ukraine with a view to stimulate the de-shadowing of income received from letting residential real estate"; introduction of a Multiple Listing Service based on real estate appraisal reports; activities of tax authorities in the field of identifying shadow transactions in the rental market. To minimize the level of shadowing the real estate sector, it is suggested to: conduct public awareness campaign as for the benefits of conducting legal activities in the rental market, e.g., protection of the rights of tenants and landlords in the field of real estate transactions; to amend the Tax Code of Ukraine regarding the taxation of income received from letting residential real estate; create a "Legal Lease" online portal, etc.

In this paper, we discuss the properties of hyperharmonic numbers {H [r] n }n 1, where r is a positive integer. We focus on the monotonicity of some sequences related to H [r] n . For example, we consider the monotonicity of the sequences such as {H [r] n /n}n 1, { n q H [r] n }n 1, { n q H [r] n+1/H [r] n }n 1, and { n+1 q H [r] n+1/ n q H [r] n }n 1.


Summary The widespread application of mass spectrometry (MS)-based proteomics in biomedical research increasingly requires robust, transparent and streamlined solutions to extract statistically reliable insights. Existing, popular tools were generally developed for specific uses in academic environments and did not fully embrace current open-source principles and best practices of software engineering. We have designed and implemented AlphaPeptStats, an inclusive python package with broad functionalities for normalization, imputation, visualization, and statistical analysis of proteomics data. It modularly builds on the established stack of Python scientific libraries, and is accompanied by a rigorous testing framework with 98% test coverage. It imports the output of a range of popular search engines. Data can be filtered and normalized according to user specifications. At its heart, AlphaPeptStats provides a wide range of robust statistical algorithms such as t-tests, ANOVA, PCA, hierarchical clustering and multiple covariate analysis – all in an automatable manner. Data visualization capabilities include heat maps, volcano plots, scatter plots in publication-ready format. AlphaPeptStats advances proteomic research through its robust tools that enable researchers to manually or automatically explore complex datasets to identify interesting patterns and outliers. Availability AlphaPeptStats is implemented in Python and part of the AlphaPept framework. It is released under a permissive Apache license. The source code and one-click installers are freely available and on GitHub at https://github.com/MannLabs/alphapeptstats. Contact email@example.com, firstname.lastname@example.com


The story of comics is also the story of the modern city. Visible Cities, Global Comics thus makes urban contribution to an interdisciplinary phase in comics studies. Striking a balance between descriptive, historical, analytical and theoretical modes, Fraser's research monograph explores representations of the city in a selection of comics from across the globe. First, this book brings insights from urban theory to bear on specific comics texts; and second, it uses comics texts to elucidate themes of urbanism, architecture, planning and the cultures of cities in works from the 18th through the 21st centuries. Throughout, close readings of comics by artists from a range of locations—Argentina, Belgium, Brazil, Canada, China, England, France, Holland, Japan, Norway, Spain, Switzerland, the United States, and Uruguay—contribute to an exploration of larger urban themes. Chapters include "The Modern City Streets" (ch. 1), "The Passions of Everyday Urban Life" (ch. 2), "Urban Planning, Built Environment and the Structure of Cities" (ch. 3), "Architecture, Materiality and the Tactile City" (ch. 4), and "Danger, Disease and Death in the Graphic Urban Imagination" (ch. 5). Fraser's writing presumes no previous knowledge of either urban theory or the ninth art. Readers are introduced to names, places, historical events, urban thinkers, and formal elements of the comics medium with which they may not be familiar. In the process, each chapter introduces readers to specific comics artists and texts and investigates a range of matters pertaining to the medium's spatial form, stylistic variation, and cultural prominence.


High-level computer vision tasks, such as object detection in single images, are of growing importance for our every day lives. Reliable systems for object detection, in particular, may simplify our lives significantly or make them safer (e.g.~in driver assistance scenarios). %This dissertation studies object detection in challenging scenes based on graphical models. Graphical models lend themselves to analyze and design computer vision algorithms because of their modularity that allows to design complex models built on simpler modules. This modularity and decomposability enables a better understanding of the domain of interest that in turn enables the design of models with increased reliability. In this dissertation we study discriminative, undirected graphical models, namely conditional random fields (CRFs), and propose extensions to standard CRFs in order to address object detection in challenging scenes. %The use of CRFs allows a fundamental understanding of the structure of the domain of interest that is crucial for reliably handling challenging scenes. %These challenging scenes require a fundamental understanding of the structure of the domain of interest. We discuss the advantages of discriminative models compared to generative variants in the presence of cluttered background, partial occlusion and viewpoint variation. While standard CRFs are restricted to fixed, local neighborhood dependencies we propose to learn arbitrary graph structures. Furthermore, we take advantage of the decomposability of graphical models and propose to interpret the random variables as object parts and develop a joint approach of part-based and monolithic object detection. This view on objects yields a better and intuitive understanding of the structure of objects, and in accordance with observations of related work we demonstrate an improved reliability of our joint system. A secondary focus of this work is the field of search and rescue robotics. Specifically, we are concerned with victim detection in search and rescue scenarios, which requires additional demands besides reliability. In this setting we require real-time capable models, hence, we need efficient algorithms without sacrificing performance. We propose to leverage the complementarity of different sensors (visual, thermal and laser in this work) within a sensor fusion scheme for an improved victim detection performance.


The vast majority of population-based optimization algorithms use selection in such a way that the nonselected individuals do not have any effect on the evolution at all, even though they may carry a valueable information — information about the local shape of the search distribution and/or about the search space areas where the search should be suppressed. This article describes a unified way of taking advantage of the information hidden in the non-selected individuals in the framework of evolutionary algorithms: first, build a classifier discriminating between selected and non-selected individuals, then turn the description of selected individuals into a search distribution, and sample new offspring from it. The concept is verified by a simple real-valued evolutionary algorithm which outperforms the state-of-the-art evolutionary strategy with covariance matrix adaptation (CMA-ES) on selected test functions in all tested search space dimensionalities. Finally, the article proposes some guidelines for future work to make this algorithm generally applicable.

In the present paper, we have theoretically predicated some significant physical parameters, i.e., coordination number, constraints, density, molar volume, cohesive energy, heat of atomization, etc., for glassy Se 80 Te 20 and glassy Se 80 Te 10 M 10 (M = Cd, In, Sb) alloys. A theoretical study of the glassy Se 80 Te 20 and glassy Se 80 Te 10 M 10 (M = Cd, In, Sb) alloys reveals that there is a significant change in the structural environment of the system due to rigidity percolation.


Probiotic use to improve health is not new; but recently, it has attracted much attention concerning human health and diseases. The human gut is a delicate ecosystem where bacteria and host cells interact with each other. This is an important part of gut homeostasis and human development. Disruption of this sensitive ecosystem may have detrimental health repercussions linked to impaired gut microbiota (GM). GM were extensively examined as an underlying mechanism for disease development and progression. Additionally, it was used as a tailored method for preventing and treating disease. Because of the strong association between GM, health, and disease, there has been much interest in employing probiotics or living microorganisms, to regulate GM to prevent or cure specific diseases. Herein, probiotics' role in enhancing women's and pediatric well-being was addressed as a marker of disease and as therapeutic avenues; where we discussed probiotics indications, efficacy, safety profiles, and future prospects in clinical practice.


Mouse CD99 and its paralog CD99-like 2 (CD99L2) are surface proteins implicated in cellular adhesion and migration. Although their distributions overlap in a wide variety of cells, their physical/functional relationship is currently unknown. In this study, we show the interaction between the two molecules and its consequence for membrane trafficking of mouse (m)CD99L2. The interaction was analyzed by bimolecular fluorescence complementation, immunoprecipitation, and fluorescence resonance energy transfer assays. When coexpressed, mCD99 formed heterodimers with mCD99L2, as well as homodimers, and the heterodimers were localized more efficiently at the plasma membrane than were the homodimers. Their interaction was cytoplasmic domain– dependent and enhanced mCD99L2 trafficking to the plasma membrane regardless of whether it was transiently overexpressed or endogenously expressed. Surface levels of endogenous mCD99L2 were markedly low on thymocytes, splenic leukocytes, and CTL lines derived from CD99-deficient mice. Importantly, the surface levels of mCD99L2 on mCD99-deficient cells recovered significantly when wild-type mCD99 was exogenously introduced, but they remained low when a cytoplasmic domain mutant of mCD99 was introduced. Our results demonstrate a novel role for mCD99 in membrane trafficking of mCD99L2, providing useful insights into controlling transendothelial migration of leukocytes. The Journal of Immunology , 2013, 191: 5730–5742. To measure FRETefficiency, images of the donor (CFP) and acceptor (YFP) were acquired before and after photobleaching of YFP to 25% of its initial intensity in selected regions of interest. FRET efficiency was calculated by using the following formula: [1 2 (CFP Intensity prebleach /CFP Intensity postbleach )] 3 100 (%). The unbleached areas were used as controls for sample movement and/or laser power fluctuations.


This study will focus on the determinants that affecting exchange rate in Malaysia. The objective of this study is to examine the relationship between Inflation Rate, Money Supply, Gross Domestic Product and Foreign Direct Investment towards Exchange Rate in Malaysia. In order to achieve the objective, this study applies the Autoregressive distributed lag model and used annually data over the period 1975 until 2015 from authorized sources. The study revealed that in ARDL Model there is a significant positive and insignificant positive relationship between Exchange rate and the selected determinants which is Inflation Rate and Money Supply respectively. Meanwhile, Gross Domestic Product and Foreign Direct Investment are found negative but significant towards Exchange Rate. This study is important for the government to retain tight monetary and fiscal policies in order to stable exchange rate in the Malaysia. Besides that, central bank will also get benefits in order to promote monetary authorities at managing exchange rate effectively.


Rates of apparent photosynthesis (APS). photorespiration (PR), CO 2 compensation (I) and dark respiration (DR) were determined on attached shoots of decaploid (70 chromosomes) and a hexaploid (42 chromosomes) genotype of tall fescue (Festuca arundinacea Schreb.) using an infra red CO 2 analyzer arranged in a closed circuit system. Plants were grown at a photon flux density 500 µmol m -2 s -1 (400-700 nm) and at 25°C. Measurements were made at 25°C in O 2 concentrations of l, 21 and 100% and at irradiance of 500 or 1800 µmol m -2 s -1 . The decaploid exhibited rates of APS that was from 26 to 46% higher in 1 and 21% O 2 but not in 100% O 2 , than those of hexaploid. Rates of PR were positively related to rates of APS. Values of r were very similar for both genotypes, they were little affected by irradiance, and were a linear function of O 2 Concentration. The percentages of PR in true photosynthesis (TPS = APS+ PR) were also similar for the two genotypes, and were a linear function of O 2 concentration. Alternatively, rates of DR were by 16-26% higher in the hexaploid than decaploid genotype, and were little affected by O 2 concentration or by previous rates of APS.


Character building is very important to become a key educational mainstream in Indonesia for formal, non-formal and informal setting. There are several factor that influence student character building, namely parenting style and genetic personality. The purpose of this research is to identify the influence of parenting style and genetic personality to student's character building. . This research is a correlational study using survey and quantitative method. The population in this study were parents who have school-age children and their children have genetic personality test (STIFIn test) in Indonesia. Data collection was carried out by simple random sampling via electronic. The returned and valid questionnaire results were 625 samples. Data collection technique is using questionnaire with likert scale. The instrument of this study is a modification from Parenting Style Questionnaire (PSQ) Robinson et al. (1995) and Roman et al. (2015). To measure the genetic personality, the instrument is adapted from STIFIn Personality Concept (Poniman & Mangussara, 2013). Another instrument used to measure student character building is an adaptation from Poniman et. Al (2014). Analysis from this study is using SEM (Structural Equation Model) with SmartPLS version 3.0 as a statistic tools. The result of this study argued that parenting style and genetic personality have a positive influence and significantly contributed to student character building. This study also reinforces the theory that student character building is significantly affected by genetic personality and parenting style. Finally, it is recommended that parents should improve the quality of parenting and need to know their chlid's genetic personality by personality test (e.g., STIFIn Test).


The zebrafish is used to assess the impact of social isolation on behaviour and brain function. As in humans and other social species, early social deprivation reduces social preference in juvenile zebrafish. Whole-brain functional maps of anti-social isolated fish were distinct from anti-social fish found in the normal population. These isolation-induced activity changes revealed profound disruption of neural activity in brain areas linked to social behaviour, such as the preoptic area and hypothalamus. Several of these affected regions are modulated by serotonin, and we found that social preference in isolated fish could be rescued by acutely reducing serotonin levels.


A finite strain large displacement model for membrane structures based on the combined finite- discrete element method (FDEM) has been developed. The model is implemented into the the open source FDEM package - Yfdem. The paper also presents benchmark tests and numerical results.


This paper Intends to tackle the topic of company communication media andtheir role in interpersonal communication processes in middle-size organizationsof service sector in Medellin city (Colombia). The scope of this research is basedon the research Project: "More media than communication in organizations: evaluation of relation between internal media communication and information and interpersonal communication inside middle-size organization of service sector in Medellin city from a Corporative communication perspective," a research in progress by CORPUS (Corporative Communication)Research Group, adscript to Universidad de Medellin School of Communications, and recognized in Category C by Colciencias.This project clearly supports the statement that organizations under analysisdevelop different communication processes with their audiences, mainly internalprocesses directed more to information that to communication which impactinterpersonal communication processes. Middle-size organizations analyzed usemore mass media than communication media, because they rely more in themass media than in possible human interactions, thus preventing humaninteractions and generating an information society and a mass society, everyday further from its essence: society


A 21-year-old Korean, single, and immigrant male presented to therapy with significant symptoms of social anxiety disorder (SAD) for treatment at a university training clinic. At the time of intake, he was experiencing intense distress and remarkable adaptations in his life to accommodate rather chronic physiological symptoms related to social interactions. He immigrated to the United States 5 years prior to treatment from Seoul, Korea. He endured social anxiety for 6 years preceding treatment. The case was conceptualized and treated from a cognitive-behavioral framework. Treatment gains were measured using behavioral markers and a reliable change index using standardized outcome measures. This case illustrates the ability to adhere to a cognitive-behavioral treatment model for SAD while considering pertinent cultural factors. Furthermore, it highlights the generalizability of a specific treatment model when working with Korean immigrants. The authors discuss the need for future research, and treatment implications of this case are described.


Raman-induced Kerr effect spectroscopy (RIKES) as a tool for the investigation of species in solution is presented. RIKES has proved to be a particularly useful probe for Raman modes of molecules in solution because control of the polarizations of the interacting laser fields allows non-resonant solvent contributions to the background to be minimized. New techniques to subtract laser power fluctuations from the signal have further increased the sensitivity of RIKES. Spectra of carbon tetrachloride, benzene and the hydroxide ion are presented to show the utility of RIKES for investigating solutions. The ability to decrease background noise by controlling the polarization of the pump laser was demonstrated by studying the 459 cm−1 carbon tetrachloride resonance. Concentration studies on benzene in carbon tetrachloride showed a narrowing of the 992 cm−1 mode of benzene as its concentration was decreased. The sensitivity of the technique is demonstrated with spectra recorded on 0.01 M benzene in carbon tetrachloride. The 3620 cm−1 OH− resonance is presented for a 10 M solution of NaOH in water. A nearby water resonance makes the OH− mode difficult to see at lower concentrations. Polarization tuning was not able to improve the RIKES sensitivity in this case.


The ultrafast photolysis of the cation complex [(cyclam-ac)FeN3 ]+ is studied by femtosecond spectroscopy with ultraviolet excitation and mid-infrared probing. Immediately after UV absorption, the excited complex undergoes internal conversion and azide dissociation within 2 ps. The subsequent vibrational relaxation in the electronic ground state and geminate recombination of the fragments take place on time scales of 13 and 20 ps, respectively.


We report the detection of broad Hα emission in three X-ray selected obscured AGNs at z ∼ 1–2. By exploiting the Hα width and the intrinsic X-ray luminosity, we estimate their black hole masses, which are in the range 0.1–3 × 10 9 M� . By means of multi-band photometric data, we measure the stellar mass of their host galaxy and, therefore, infer their MBH/Mstar ratio. These are the first obscured AGNs at high-z, selected based on their black hole accretion (i.e. on the basis of their X-ray luminosity), that can be located on the MBH − Mstar relation at high-z. All of these obscured high-z AGNs are fully consistent with the local MBH − Mstar relation. This result conflicts with those for other samples of AGNs in the same redshift range, whose MBH/Mstar ratio departs significantly from the value observed in local galaxies. We suggest that the obscured AGNs in our sample are in an advanced evolutionary stage, have already settled onto the local MBH-Mstar relation, and whose nuclear activity has been temporarily revived by recent galaxy interactions.


Many elements can be combined in the formation of high-entropy-alloy nanoparticles Different materials and the capabilities they enabled have marked the ages of civilization. For example, the malleable copper alloys of the Bronze Age provided harder and more durable tools. Most exploration of new alloys has focused on random alloys, in which the alloying metal sites have no metal preference. In binary and ternary metal systems, dissimilar elements do not mix readily at high concentrations, which has limited alloying studies to intermetallics (ordered multimetallic phases) and random alloys, in which minor components are added to a principal element. In 2004, crystalline metal alloys consisting of five or more principal elements in equal or nearly equal amounts (1, 2) were reported that were stabilized by their high configurational entropy. Unlike most random alloys, the "high-entropy" alloys (3, 4) reside in the centers of their multidimensional phase diagrams (see the figure, right). On page 1489 of this issue, Yao et al. (5) present an innovative and general route to high-entropy alloys that can mix up to eight elements into single-phase, size-controlled nanoparticles (NPs).
