Writing is a proficiency which is very difficult and complex. This is because the learner needs many aspects to master, such as lexical aspect, grammatical aspect, the ability to present facts and express their thoughts, etc. According to the results of the final review of the 4th semester students, we found that students have encountered a lot of grammatical errors in the course of writing. As a result, we search for analysis to identify this problem and find solutions. Therefore, the problem proposed in this research is: 1) what type of error is often done by students in the course of writing? (2) What is the grammatical error which is found a lot depending on the result type? (3) What are the solutions to solve them? In order to find answers to this problem,we did a descriptive qualitative research with qualitative method by analyzing of the errors. We found that: 1) the dominant type of error is the grammatical error, 2) the most significant type of grammatical error is the error of the adjective. So, in order to solve the problems, students must have a good grammatical skill in the first half; we have to make the students know their grammatical errors even if it's very simple, give more exercises in the students so that they are used to write correctly


The aim of this study was to investigate the utility of incorporating active matrix metalloproteinase-8 (aMMP-8) as a biomarker into the new periodontitis classification system (stage/grade) presented in 2018. This study included 150 Greek adults aged 25–78, of whom 74 were men and 76 women. Participants were tested with an aMMP-8 point-of-care mouthrinse test, after which a full-mouth clinical examination was performed to assess their periodontal and oral health. The aMMP-8 levels in mouthrinse were significantly lower among healthy patients compared with patients in more severe periodontitis stages and grades (Kruskal–Wallis test and Dunn–Bonferroni test for pairwise post-hoc comparisons; p < 0.01 and p < 0.05, respectively). Furthermore, aMMP-8 levels were less correlated with plaque levels than bleeding on probing (BOP) (Spearman's rho = 0.269, p < 0.001; Spearman's rho = 0.586, p < 0.001); respectively). Thus, aMMP-8 was more robust to the confounding effects of oral hygiene than traditional periodontal parameter bleeding on probing. The aMMP-8 point-of-care mouthrinse test can be utilized as an adjunctive and preventive diagnostic tool to identify periodontal disease, classified by stage and grade, and ongoing periodontal breakdown chairside in clinical practice in only 5 min. Overall, integrating aMMP-8 into the new periodontitis classification system seems beneficial.


This issue ofLanguage Testingfocuses on an area that continues to fascinate and trouble many of us: assessing language for specific purposes (LSP). The five articles in this issue present a range of challenging issues and findings that will inform our understanding of LSP assessment, but also further problematize it. This is no bad thing as English spreads wider still around the world and more and more users see English as a wholly instrumental skill in their lives. The issues apply, of course, equally to languages other than English. Davies questions the English for Specific Purposes (and by extension, the LSP) enterprise on both practical and theoretical grounds. Davies rejects the notion of considering Specific Purposes (SPs) as registers alone, agreeing with Widdowson and others that SPs are characterized by their communicative natures. As he points out, with communication in mind, we are in the territory of discourse and therefore of blurred boundaries. This is an issue which is also taken up by Elder and Cumming in this issue. Davies' critique of the IELTS development, and of the validation study of the original ELTS, leads him to question the influence that SP factors (linguistic or discoursal) have in test-taker performances relative to other factors, such as mastery of the language core (grammar, core lexis, etc.). Davies concludes that, to date, SP tests can only be judged on the pragmatic criterion of test usefulness. In her article, Elder uses three language tests for teachers to examine the problem of indeterminacy in LSP tests, in the process of which she calls into question the notion that any test has an inherent claim to validity by virtue of its SP-ness. The tests illustrate some of the diversity of issues that may arise when we consider the language ability needed by both subject teachers and foreign language teachers.

The Pasvik River shapes the greater part of the border between Russia and Norway. This body of water was a site of Norwegian–Soviet energy cooperation from the 1950s until the late 1970s. Norwegian firms constructed four hydropower stations in a strategically sensitive area. Drawing on Soviet and Norwegian archival materials, this study analysed the heterogeneous interests and negotiation processes that resulted in long-term hydropower cooperation. The powerhouses were designed to produce both electrical and political energies for transfer across the border. These infrastructural projects fit into the contemporary narrative of peaceful coexistence and prompted a firm cooperation between the two countries. Norwegian workers built power plants on Soviet soil, thereby legitimizing the Norwegian social democrats' policy of rapprochement. The Soviet government and media portrayed the construction as physical proof of good neighbourly relations. Not only state actors but also members of the Norwegian–Soviet Friendship Society aimed to appropriate the powerhouses for their specific goals. They worked to soften the border regime between the two countries, thus initiating a locally limited visa-free entry zone. However, this project was short-lived because Norwegian–Soviet cooperation at the border was restricted to the realm of energy production.


This study aims to develop a transmission mechanism for a PD220Y bulldozer through revising it from a manual to an electronic-operated manner. To enhance operability and performance of the transmission system, a systematic design methodology is employed to select and redesign major comonents. Simultaneously, the transmission system can be further improved via oil pressure testing.

A simple experimental approach was developed to measure the gas phase volumetric heat and mass transfer coefficients in a bubble column and a slurry bubble column employing a single gas nozzle. The experimental technique was based on a transfer model that simulates humidification and direct contact evaporation models in the case of a gas bubble rising in a liquid of uniform temperature. The temperature and relative humidity of the inlet and outlet gas in the column are the only measurements required in this technique. Experiments were carried out in a 0.15 m inner diameter column using water as the liquid phase, air as the gas phase, and cation resins of 0.1 mm diameter and a specific gravity of 1.2, as the solid phase. The results showed that, when using solid concentrations in the range of 7–10 wt %, both the volumetric gas-phase heat and mass transfer coefficients increased with an increase in the gas superficial velocity and were further enhanced by increasing the solid load after a certain minimum superficial velocity had been reached in the column (0.044 m/s in the system used). Increasing the solid load beyond 10 wt %, did not contribute to a further increase in these coefficients. Furthermore, the gas holdup in the column increased with the superficial gas velocity and was further enhanced when the solid-phase load was in the range of 7–10 wt %. These observations agree well with previously reported findings by other investigators.


We study electron transport in a double quantum dot in the Pauli spin blockade regime in the presence of strong spin-orbit coupling. The effect of spin-orbit coupling is incorporated into a modified interdot tunnel coupling. We elucidate the role of the external magnetic field, the nuclear fields in the dots, and the spin relaxation. We find qualitative agreement with experimental observations, and we propose a way to extend the range of magnetic fields in which blockade can be observed.


A novel in-plane double silicon-on-insulator optical MEMS accelerometer based on variable optical attenuator is presented. It is designed for micro-satellite navigation applications and it uses multimode waveguides integrated with MEMS providing a compact and reliable device.


More African-American and African dance professionals need to be part of higher education. More research needs to be done on figures lost to history. More questioning needs to be done about modes of representation of race in American dance. Perhaps most importantly, we need to keep dancing our concerns. In the case of Ron Brown, this was vividly illustrated. With a chameleonlike facility to alter his body, this stunning dancer seemed to pulsate through the myriad meanings of being "black" today—shifting from hip hop to African dance imagery to ritualistic gesturing to modern dance leaps to his own personal movement style. One person said afterwards that the dance was so amazing that it made her eyes burn. Certainly, this is an image we need to take into the classroom as we strive to reimagine America.


A suction nozzle for a vacuum cleaner is provided to prevent contraction of a pedal support part by dividing a pressure pedal into the pedal support part and a pedal cover, and to improve the rigidity by increasing the thickness of a rib formed in the lower part of the pedal support part. A suction nozzle for a vacuum includes a body in which a suction pipe is turned and installed, a turn regulating unit for restricting rotation of the suction pipe, a height adjusting unit for adjusting the height of the body, and a pressure pedal for transmitting pressure to the turn regulating unit or the height adjusting unit and having a pedal support part(372) and a pedal cover(378) placed in the pedal support part. Plural ribs are formed in the lower part of the pedal support part, and a seating part is stepped in the pedal support part to place the pedal cover.


Currently, there are quite a lot of incorrect procedures and mistakes that occur in the forensic area, which lacks analytical approaches toward solving the causes of accidents using s–t diagrams (distance–time diagrams) combined with the software simulation applications. When analyzing accidents, the correct information is of key importance. The aim of this article is to define a new specific technical and analytical approach toward handling expert's reports on traffic accidents in road transport at intersections, with respect to the traffic lights. A simulation program application is used as a progressive means of accident evaluation. This procedure must become a standard in the methods of modern traffic accident analysis. The application of this methodology with simulation tools for accident reconstruction enables one to perform a very precise analysis of traffic accidents. Mutual space and time relationships of vehicles' movements have been evaluated here, depending upon the intersection signal plan. To demonstrate the methodology, a real case is used here, reconstructed by means of the complex analytical simulation software PC-Crash. A procedure processed by these means can be beneficial for forensic traffic accident analysis.


In this paper we study the large-time behavior of solutions of one-dimensional fractional Fisher-KPP reaction-diffusion equations, when the initial condition is asymptotically front-like and it decays at infinity more slowly than a power $x^{-b}$, where $b<2\alpha$ and $\alpha\in(0,1)$ is the order of the fractional Laplacian. We prove that the level sets of the solutions move exponentially fast as time goes to infinity. Moreover, a quantitative estimate of motion of the level sets is obtained in terms of the decay of the initial condition.


Little is known about the epidemiology of infections causing peritonitis in continuous ambulatory peritoneal dialysis (CAPD). The commonest cause, coagulase-negative staphylococci (C-NS), are normal skin flora. The main source is thought to be organisms from the patient's own skin or environment. Using plasmid profiles as an epidemiological marker, the authors identified cases in which surveillance skin cultures taken just before an episode of peritonitis were identical to those isolated from the effluent. On comparing the plasmid profiles from the effluent of patients who had multiple episodes over eight weeks, they identified two patterns. One group had different plasmid profiles between episodes of infection. The second group (the majority of the cases) had identical plasmid profiles between the initial episode and the second which occurred between 10 days and four weeks after stopping antibiotics. This suggests that, in most cases of recurrent infection studied, the second episode represented a reinfection or recurrence with the same organism (as the initial episode). Slime production did not discriminate those patients who would develop recurring peritonitis.


It's a effective measure to check the quality of piles by using ultrasonic. The reflection wave can't be shown directly if coupling degree with pile is bad. But it can be shown better if the signal has been filtered by modern power spectral estimation.


In this paper we give a simple formula to obtain hereditary symmetries related to the isospectral eigenvalue problem of integrable equations. Using this formula, (i) we prove that eigenfunctions of hereditary strong symmetry are symmetries for the whole hierarchy, which improves the result of Fokas and Anderson [J. Math. Phys. 23, 1066 (1982)]; (ii) we find new integrable equations; and (iii) we give strong symmetries of these new integrable equations and various equations for eigenfunctions of the isospectral eigenvalue problems.


This chapter describes how meaning, as in "the meaning of life," made its appearance in the English language. Credit goes to Thomas Carlyle (1795–1881), a Scot whose Presbyterian worldview features a doctrine of divine immanence, of nature as a revelation of the divine. He was fond of the image of a figurative veil separating the world of appearances from a sacred world behind it. Carlyle introduced the English-speaking world to Novalis, whose writing he regarded as pervaded with mysticism and idealism. He wrote of the "Volume of Nature" and introduced the phrase "meaning of life" to the English-speaking world. He used the word meaning by itself, to suggest "purpose," "worth," "religious truth." Aspects of Carlyle's worldview, as well as his infatuation with Novalis, moved west to the United States thanks to the friendship that Ralph Waldo Emerson struck up with the Scottish writer. Not only did the New England Transcendentalist help introduce Carlyle's writings to American readers, but his own writings became infused with Carlyle's thinking, above all in his predilection for discovering, in nature, meaning and meanings—never defined and always infused with mystery.


In order to endue the underfill with reworkability, tertiary ester epoxy resin (TEER), bis[1-methyl-1-(6-methyl-7-oxa-bicyclo[4.1.0]hept-3-yl)-ethyl] isophthalate, was synthesized by the reactions of esterification and epoxidation. The structure was characterized by Fourier transform infrared With TEER as matrix, silica particles as filler, methyl hexahydro-phthalic anhydride (MeHHPA) as curing reagent and 2-Ethyl-4-methylimidazole (4E2MI) as accelerant, the underfill was successfully prepared. The ester group in the backbone would be pyrolyzed when it was heated. The sharp peak of pyrolysis curve by differential scanning calorimeter indicates the pyrolysis process has less side reaction and the pyrolysis range is around 220 °C. The pyrolysis is a carbenium intermediate process which relates to the stability of the carbenium. Tertiary carbenium is more stable which makes TEER have a lower pyrolysis temperature. Processing characteristics measurement results show that the reworkable underfill exhibits excellent processing performances and the tertiary ester epoxy resin is suitable for reworkable underfill.


The paper presents the main types of mechanisms used within the connecting systems from the high- and low-voltage electric grid. The purpose is the accurate construction of the kinematic diagrams of the mechanisms of electrical connection. For the low voltage connecting systems the topological structure of three kinematic schemes of articulated plane mechanisms is analysed. The structural-topological analysis is extended to other three kinematic schemes of simple plane mechanisms used as high voltage connecting systems. The structural-topological study is then applied to the complex plane mechanisms used as high voltage separators.


Do African indigenous legal institutions, especially those that occupy space in continental and even international human rights discourse today, have any legitimacy? In other words, where does the legitimacy of a people's custom, traditional practice or culture generally reside? This question is pertinent to the general understanding of the human rights situation in Africa because it demands an explanation as to why certain traditional practices and institutions of indigenous law have survived centuries of bludgeoning and remonstrations. It also casts the international imagery of rights against a prism of multicultural idealism that seems to experience something of rebirth in the past two decades or so. So whereas human rights ideologues can boast of having bridged the gap between die hard relativism and the more infl uential universalism, there seems to be an addendum to the debate that still begs scholarly attention. And that is whether human rights should be a product of a people's consciousness, written with affi rmation of principles that enjoy legitimacy within those persons or groups of persons from whom compliance is sought. This issue hinges on another subtle question: whether the human rights agenda can rise above the unbalanced liberal discourses that have abetted the alienation of communities from their cultural environment and controlled their political thought process. One might remember that this is exactly what Christianity did during the European infi ltration of the African continent in the 18th century. While it is our contention that legitimacy is at the core of the human rights agenda, in this article we are not concerned per se with the broader aspect of "suffi ciency" or "insuffi ciency" of cultural legitimacy of human rights, but rather, with how the question of legitimacy affects the relationship between indigenous legal institutions and human rights practice in Kenya. The point sought to be made is that the propagation of human rights in a multicultural environment that


Documents related to the case of The State of Texas vs. John Lavaser, accused of theft of tobacco and ground peas, filed July 16, 1874. Documents are an arrest warrant for John Lavaser and a bill of indictment signed by grand jury foreman N. P. Coleman.


A study on the contents and pollution state of heavy metals in the soils at the Xiaoyi Bauxite Mine in Shanxi, China was conducted to provide a scientific basis for understanding and evaluating the risks of heavy metal pollution in reclaimed soils in mining areas. The contents of Cd, Cr, Cu, Pb, As, and Ni were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and evaluated with respect to the changes in their characteristics over different reclamation years. Using a single factor index and the Nemerow Pollution Index, the potential degree and risk of pollution were assessed. The mean concentration of Cd was 5.19 mg/kg, which exceeds the 0.3 mg/kg national standard in China by 17 times, while the concentrations of other elements did not exceed the national standard and there was no apparent pollution risk. With the extension of the reclamation time, the contents of Cd increased in the 0–15-cm layer and decreased in the 15–30-cm layer. Cadmium possessed the highest single pollution index, and exceeded the severe pollution level (Level 5), while the other five elements were at safe levels (i.e., lower than Level 1). The Nemerow Pollution Index ranged from 12.08–13.14, with an average of 12.43, and exceeded Level 5 pollution by 3–4 times, indicating a severe level of pollution. The soil being used to reclaim the mine was the main source of pollution, with the contents of six heavy metal elements exceeding the national standards. The soils in the reclamation area contain Cd pollution from the resource soil, manure, and dust. Therefore, for mine reclamation, the quality of the soil being used to reclaim the land should been stringently control.


A fleet of autonomous mobile robots are used in the hospital for the delivery service. To increase the efficiency of using multiple robots, an appropriate task allocation algorithm is required. This paper explains the task allocation procedure for multiple robots and introduces two multi-task allocation (MT) algorithms to be applied in the hospital delivery service. The algorithms are tested via simulation, and the performance are compared according to the criteria. The result shows that proposing combinatorial search algorithm with limited capacity performed better among others.


Modern forest selection programs concern natural and protected populations of trees characterized by a great genetic variability and also production stands frequently deformed by human activity. In the latter, artificial regeneration is prevailing. Forest nurseries working in the organizational structures of State Forests can guarantee the proper provenance (genotype) of seeds and the quality of seedlings obtained from them. The condition, however, is a close uniformity in the conservation of forest gene resources, and selection breeding of forest trees. The success of the program depends also on the development of modern infrastructure for forest nurseries and applied technologies. The latter task was the field of activity of Professor Bolesław Suszka, Ph.D., and his many-year research and organizational and didactic activity in Poland and abroad. The methods in long-term storage and their pretreatment in case of dormant seeds, developed by Professor Suszka, created the theoretical and practical basis for the conservation of forest gene resources not only


Abstract. We present IT-SNOW, a serially complete and multi-year snow reanalysis for Italy (∼ 301 × 103 km2) – a transitional continental-to-Mediterranean region where snow plays an important but still poorly constrained societal and ecological role. IT-SNOW provides ∼ 500 m daily maps of snow water equivalent (SWE), snow depth, bulk snow density, and liquid water content for the initial period 1 September 2010–31 August 2021, with future updates envisaged on a regular basis. As the output of an operational chain employed in real-world civil protection applications (S3M Italy), IT-SNOW ingests input data from thousands of automatic weather stations, snow-covered-area maps from Sentinel-2, MODIS (Moderate Resolution Imaging Spectroradiometer), and H SAF products, as well as maps of snow depth from the spatialization of over 350 on-the-ground snow depth sensors. Validation using Sentinel-1-based maps of snow depth and a variety of independent, in situ snow data from three focus regions (Aosta Valley, Lombardy, and Molise) show little to no mean bias compared to the former, and root mean square errors are of the typical order of 30–60 cm and 90–300 mm for in situ, measured snow depth and snow water equivalent, respectively. Estimates of peak SWE by IT-SNOW are also well correlated with annual streamflow at the closure section of 102 basins across Italy (0.87), with ratios between peak water volume in snow and annual streamflow that are in line with expectations for this mixed rain–snow region (22 % on average and 12 % median). Examples of use allowed us to estimate 13.70 ± 4.9 Gm3 of water volume stored in snow across the Italian landscape at peak accumulation, which on average occurs on 4 March ± 10 d. Nearly 52 % of the mean seasonal SWE is accumulated across the Po river basin, followed by the Adige river (23 %), and central Apennines (5 %). IT-SNOW is freely available at https://doi.org/10.5281/zenodo.7034956 (Avanzi et al., 2022b) and can contribute to better constraining the role of snow for seasonal to annual water resources – a crucial endeavor in a warming and drier climate.


At this stage in the Symposium three papers have been presented on the subject of Supersonic Flight. They will have left untouched a field which is much too wide and extensive to cover in a single paper. In fact, any attempt to cover the major problems remaining would result in a superficial and valueless effort. However, the general problem of control, particularly that resulting from the elimination of the pilot, is clearly the next major consideration and this is basically the theme of this paper. Other major problems may be described as those associated with Electrical and Mechanical Engineering; they include power supplies, services and, in particular, refrigeration. If one looks back some twenty years these problems were not considered of any great importance, although at some stage every designer must have decried their reliability. In fact " electrics again " seems to have been heard far too frequently when trouble occurred.


Nonnegative matrix factorization- (NMF-) based noise reduction methods can effectively improve the performance of environmental sound recognition. However, when the environmental sound overlaps highly with the noise, the spectral line loss and noise residue will occur in the low signal-to-noise ratio (SNR) condition. An adaptive noise reduction algorithm was proposed in this paper. First, noisy environmental sound is separated into estimated noise and environmental sound using NMF. Then, the estimated noise is used to calculate sound presence probability (SPP), which is adapted to decrease spectral line loss and achieve accurately estimated noise. Subsequently, the estimated noise combines with noisy environmental sound to obtain the estimated environmental sound. Finally, SPP is applied to reduce residual noise in the estimated environmental sound and reconstruct the environmental sound. The simulation results demonstrate that the proposed algorithm outperforms the traditional algorithms and NMF-based methods in terms of perceptual evaluation of speech quality (PESQ) and global SNR with increase of X% and X%, respectively. Moreover, the proposed method can effectively improve the environmental sound recognition rate. Particularly, the proposed method makes a 16.2% increase of F1-score in car horn recognition under the realistic acoustic condition.


As this penetrating survey indicates, the need is for long term followup of self poisoning of children and adolescents. We must learn more about the incidence of repeated ingestions, drug abuse, suicide attempts, com pleted suicide and incapacitating disorders of personality and behavior.


Soil aggregates are the basic structural components of soil, which are important factors that can predict erosion resistance. However, few researchers have investigated the effects of forest conversion on the stability of soil aggregates, particularly in subtropical forests. In this study, soils from various depths (0 to 30 cm) were collected from four forest types (transformed from broadleaved forests (BMF) to combined coniferous broadleaved (CBMF), Chinese fir (FF), and bamboo forests (BF)) to determine the impacts of forest conversion on the physical and chemical properties of soil, water-stable soil aggregates, and aggregate-associated humic substances. The results showed that forest conversion had no effects on the soil's physical properties, or the humic substances in bulk soil, but had significant effects on soil aggregates. In addition, the conversion of broadleaved forest to Chinese fir forest increased the soil stability, and to bamboo forest, decreased the soil stability. Finally, the soil's physicochemical properties were closely related to aggregate-associated humic substances. In summary, specific forest management measures should be applied to strengthen the positive impacts and reduce the negative impacts associated with forest conversion.


AIM
To develop a nanocarrier for targeted delivery of agents to the cartilage.

MATERIALS & METHODS
Chondrocyte affinity peptide modified PEGylated polyamidoamine conjugates (CAP-PEG-PAMAM) were prepared and rhodamine B isothiocyanate (RB) fluorophore was linked on them for comparative biological tracing and profiling.

RESULTS
CAP4-PP-RB exhibited much more efficient cellular uptake in vitro than that of PEG-PAMAM-RB. Both the conjugates were likely internalized by chondrocytes via clathrin and caveolin co-mediated endocytosis, and delivered to lysosomes. In vivo imaging demonstrated the fluorescein-labeled nanocarrier was capable to persist in the joint cavity of rats for a prolonged time. Furthermore, the CAP4-PEG-PAMAM showed a good biocompatibility and enhanced penetration effects in vivo.

CONCLUSION
CAP-PEG-PAMAM could be an effective nanocarrier for intra-articular delivery of agents to cartilage.


Abbott's Compounding Pharmacy in Berkeley, Calif., is voluntarily recalling all unexpired lots of sterile compounded products because of lack of sterility assurance.


In a previous article [2] it was shown that if A is a simple closed symmetric operator with deficiency indices (1, 1) in a Hilbert space H and if A has a selfadjoint extension Ao in H with a discrete spectrum, then every selfadjoint extension and every minimal selfadjoint dilation A+ of A has spectral multiplicity 1. Further, it was possible to make certain statements about the spectrum of A+. In the present article it is shown that if A has a self adjoint extension A 0 with a twice continuously differentiable spectral function, whose derivative is always positive, then there are minimal selfadjoint dilations A+ of A for which the spectral multiplicity is two; indeed, there are minimal selfadjoint dilations A+ which are unitarily equivalent to the multiplication operator in L2(o, co)EDL2(o, oc). As in [2] the proof of these facts depends upon obtaining an expansion theorem which is valid for each of the selfadjoint extensions or dilations A+. This expansion theorem is the analog of the well-known expansion theorems for linear ordinary differential operators; however, it is necessary in deriving it to overcome the fact that, unlike a linear ordinary differential operator, there does not necessarily exist a basis of entire functions for the solutions of the equation Af =Xf. After the expansion theorem is obtained, it is used to define a unitary map of H+ (the space in which A+ acts) onto L2(oc, oc) fL2(o , oc). The same map takes A+ into the multiplication operator in L2(oc, oc) EL2(-oco o). Throughout this article we shall adhere to the notation of [2], except that we shall use the symbol Q(X) in place of Q,(X). We begin with a lemma on the limit of a function analytic in the upper half-plane as one approaches the real axis.


This experiment was conducted to study the effect of special fermented soybean meal on growth performance and the development of gastrointestinal tract in weaned piglets.Ninty weaned piglets(Duroc×FengJing×JangQuHai) weighing an average of(4.75±0.38) kg at 26 days age were randomly assigned into two treatment groups with three replicates and 10 piglets with each pen,according to litter and body weight.Piglets in treatmentⅠwere fed with 17.5 percent of special fermented soybean meal and with 35 percent in treatment Ⅱ.The result showed that there were significant effects on percentage of daily gains,percentage of diarrhea rate,gastric contents pH,gastric mucosal thickness and gastric wall thickness in two treatment groups.The feed/ weight of two treatments decreased by 4.21% and 19.47% in treatment Ⅱ(P0.01).The Villus height Cript depth gastric and wall thickness increased significantly in treatments.Besize,that in treatmentⅠhad also an improvement.These results indicated that special fermented soybean meal could improve growth performance of weaned piglet,decrease diarrhea rate and improve the development of gastrointestinal tract significantly.


English language corpora, by making authentic language available for language teaching, have helped to redefine the notion of 'standard' to which language learners should aspire. As they have come to contain the widest possible range of varieties of English, they invariably also include usage which contradicts the approximative rules of intermediate grammar. Such pedagogically 'unwelcome' usage may at first sight confuse learners still concerned with what is 'right' or usage may at first sight confuse learners still concerned with what is 'right' or 'wrong' in English and unable to distinguish between different genres, registers and text-types. And surely, in the beginning and intermediate stages at least, it does not make sense to teach structures which are 'mostly correct' or 'sometimes acceptable'.At closer inspection, however, the above concern is only justified for a very narrow conception of language teaching, namely that of an ex cathedra impartion of linguistic wisdom. Dealing with perfective aspect, this paper examines the nature of pedagogically 'adverse' corpus findings in relation with adverbialmarkers hitherto, yet and since when. It concludes that this type of corpus evidence requires a different, constructivist, treatment of the concept of 'grammatical rule' in learning and teaching English.


The authors made an analysis of results of surgical treatment of 215 children and adolescents aged 5 to 20 years. Carcinoma of the thyroid gland was diagnosed in 25.6% of the patients. The operations were organ-saving and oncologically adequate. An analysis of long-term results has shown the survival of the absolute majority of the patients and good functional compensation of the thyroid remnant.


We read with interest the article by Pinto and his colleagues, who describe a case report of coronary artery bypass grafting surgery (CABG) in a transplanted heart [1]. With increased longevity in Western countries, the number of patients with end stage heart disease is increasing and studies have reported that advanced age should not be a contraindication for heart transplantation [2]. On the other hand, this philosophical change will add to the recognized gap between available donors and recipients for heart transplantation. The use of marginal donors is therefore a potential strategy to increase donor recruitment and indeed the use of this strategy has been successful in high volume transplant centers [3–5].

We recently encountered a critical clinical situation, in which a marginal donor with significant coronary artery disease was accepted for a recipient who was in cardiogenic shock despite of maximal medical and mechanical support. A 74-year old man presented with ischaemic cardiomypathy with an ejection fraction of 13%. He had a positron emssion tomohgraphy (PET) scan, which demonstrated that he had viable hibernating myocardium in a large portion of his anterior wall, suggesting that he would benefit from coronary revascularization. He underwent two-vessel CABG with vein grafting to left anterior descending artery (LAD) and posterior interventricular branch of the right coronary artery and left ventricular aneuryzm repair. He required inotropic support and an intra-aortic baloon pump (IABP) to wean from bypass. After extubation, the IABP could not be weaned, however all other organ systems were functioning perfectly. The patient was listed for a cardiac transplant with the condition that we would only accept a heart that had been turned down by every other institution in the national system. Fortunately a heart did become available from a 45 year-old donor that was refused due to moderate left ventricular dysfunction by echocardiogram and the presence of a lesion in the LAD on the coronary angiogram. Donor procurement was uneventful and after cardiectomy and insertion of the donor heart, during de-airing the previous vein graft was re-anastomosed to the distal LAD. The patient was weaned smoothly from cardiopulmonary bypass and transoesophegeal echocardiography showed that the left ventricular function was normal. The postoperative course was smooth and the patient continues to do well one and half years post transplant with excellent compliance. Follow-up echocardioghraphy has demonstrated that the donor heart has an ejection fraction estimated at 55%. These cases highlight the need for careful re-assessment of marginal donors and perhaps suggest that a "second draft choice" list be considered for this cohort by transplant teams.

About 400 second chromosomes were extracted from the Aomori population, a northernmost population of D. melanogaster on Honshu in Japan, and the following experimental results were obtained. (1) The frequency of lethal chromosomes was 0.23. (2) The effective size of the population was estimated to be about 3000, from the allelism rate of lethal chromosomes and their frequency. (3) The detrimental and lethal loads for viability were 0.243 and 0.242, respectively, and the D / L ratio became 1.00. (4) The average degree of dominance for mildly deleterious genes was estimated to be 0.178 rt 0.056. ( 5 ) Additive (U:) and dominance (U;) variances of viability were estimated to be 0.00276 rt 0.00090 and 0.00011 f 0.00014, respectively. (6) There was no significant difference in environmental variances between homozygotes and heterozygotes. Using these estimates, we discuss the maintenance mechanisms of genetic variability of viability in the population. The mutation-selection balance explained these experimental results. HE results of recent analyses of natural populations of Drosophila melanoT gaster indicate that there is a north-to-south cline in magnitude of genetic variability of viability [the Raleigh, North Carolina, population in MUKAI et a l . (1 974), the Orlando-Lake Placid, Florida, population in MUKAI and NAGANO (1983) and the Ishigakijima, Japan, population in TACHIDA, et al (1983)], and that some kind of balancing selection is operating in the southern population, although a mutation-selection balance holds at the majority of loci (MUKAI and NAGANO 1983). If this result is extended to a northern population, it may be expected that there is a population in which mutation-selection balance can explain the whole genetic variation with respect to viability in a population. Thus, we analyzed a northern population of this species in Japan, and the expectation was borne out. MATERIALS AND METHODS Extraction of second chromosomes: Two samples of a natural population of D. melanogaster were collected with a net at two different times in the fall of 1977 in a fruit-farming area in Hirosaki, Aomori prefecture (a northern population of this species). These samples are called AM-77 in this Genetics 108: 393-408 October, 1984. 394 S. KUSAKABE AND T. MUKAI paper. The first collection was made in vineyards. From this sample, 112 second chromosomes were extracted from males and 133 from females. The second collection was made mainly in apple orchards, and 137 second chromosomes were extracted from males and 50 from females. These two collections are hereafter called sample A and sample B, respectively. All of the extractions were made with the Cy/Pm [ln(2LR)~Ml/ln(2LR)bwv'] stock, following the scheme described by WALLACE (1956). Each of these chromosomes was maintained at 18" as a line balanced with In(2LR)SMl, Cy chromosomes. Cytological examination and enzyme assay: Cytological examination of salivary gland chromosomes was conducted for each chromosome line after a cross was made to the cn bw line with the standard chromosomes. The following four enzyme loci known to be located in the second chromosome were examined: aGPDH (2-17.8), MDH (2-35.3), ADH (2-50.1), HEX-C (2-74.5) and AMY (2-77.3). The four dehydrogenases were assayed by starch gel electrophoresis (CJ: SHAW and PRASAD 1970). whereas a-amylase was assayed by acrylamide gel electrophoresis (cf: PRAKASH, LEWONTIN and HUBBY 1969). For the analysis of linkage disequilibria the x2 method was employed (4 MUKAI, WATANARE and YAMACUCHI 1974). Estimation of the rate of allelism among lethal chromosomes: For estimating the effective size of the population, the allelism tests among lethal chromosome lines were done for the two samples. Fortysix lines bearing recessive lethal genes were used from sample A, whereas 48 lines were used from sample B. Crosses were made between Cy/l, and Cy/l, where 1 indicates a lethal-bearing chromosome, and subscripts i and j stand for line numbers. If the lethals of the chromosomes of lines i and j are allelic, all of the progeny show the Cy phenotype; otherwise the Cy and wild-type flies segregate. Estimation of relative viabilities: A total of 239 wild second chromosomes from sample A were used in the estimation of relative viab es. Homozygote and heterozygote viabilities were estimated with the Cy method as in WALLACE (1956). The procedure for the estimation of viability was the same as that of MUKAI and YAMACUCHI (1974). Crosses were made between five Cy/+, females and five Cy/+, males with four simultaneous replications in each chromosome line, where i indicates line number. Random heterozygote cultures were made simultaneously in the following fashion; Cy/+, x Cy/+,+,(i = 1 n ) , where n is the number of lines in one set of the experiments, for random combination of different chromosome lines. The last line was crossed to the first line. In the offspring, the expected segregation ratio of the Cy and wild-type flies in both the homozygote and heterozygote crosses was 2: 1. Relative viability was expressed as 2b/(a + l ) , where b is the number of +/+ flies and a stands for the number of marker flies, and 1 in the denominator being HALDANE'S ( 1 956) correction for the bias in averaging ratios. Ten sets of crosses were made at ten different times, and 16-31 lines were employed in each set. The chromosome lines for each set were chosen at random from those originating from males and females. Homozygote and heterozygote viabilities were estimated at the same time within each set after standardizing relative to the average viability of the heterozygotes in each set. Altogether, 998,254 flies were counted in these viability crosses. Detrimental load to lethal load ratio (D/L ratio) was estimated using the method of GREENBERC and CROW (1960). Estimation of the average degree of dominance and the environmental variance for viability polygenes: Ninety-seven second chromosome lines that originally showed homozygous viability indices larger than 0.6 of the average viability of random heterozygotes in the previous section were used in this experiment to estimate the average degree of dominance of viability polygenes. Homozygote and heterozygote viabilities were estimated in the same way as in the previous section. T w o sets of crosses were made at two different times within a month. Forty-six and 51 chromosome lines were employed in these sets, respectively. The number of simultaneous replications per line was eight. There was n o missing replicate. After the experiment, it was found that eight of 97 chroinosonie lines showed their homozygous viabilities to be less than 0.6, and one heterozygote showed a large reciprocal difference in its viability. Thus, the crosses including these lines were excluded in the analyses. As a result, 82 crosses were employed for the analysis. The total number of constituent chromosome lines was 87. Fifty-six of 82 were inversion-free heterozygotes. In total, 765,527 flies were counted in this experiment. The average degree of dominance for viability polygenes was estimated by the regression method of MUKAI and YAMACUCHI (1974). The expected regression of heterozygote viability ( Y ) on the sum of the two constituent homozygote viabilities (X) on chromosome basis estimates MUTATION-SELECTION BALANCE 395 the harmonic mean of the degree of dominance of newly arisen mutant viability polygenes (b) and, at the same time, this gives the average degree of dominance of viability polygenes in an equilibrium population (&) (MUKAI and YAMACUCHI 1974; also see MORTON, CROW and MULLER 1956). On the other hand, the regression coefficient of X on Y ( /3~,~) approximately gives the inverse of the arithmetic niean of the average degree of dominance of newly arisen mutant viability polygenes (MUKAI and YAMACUCHI 1974). All of the heterozygotes whose constituent chromosomes have viability indices larger than 0.6 were chosen for the estimation of the average degree of dominance. For the calculation of the regression coefficients, the genetic variance of homozygotes, the genetic variance of heterozygotes and the genetic covariance between heterozygotes and the sum of the corresponding homozygote viabilities were estimated by the analysis of variance removing nongenetic variations. If the In(ZLR)SMZ,Cy chromosomes show incomplete dominance over the wild chromosome, then this estimate of h should become a slight underestimate (MUKAI 1980). The environmental variance was estimated according to the following procedure. With the Cy method, Cy/+ and +/+ flies segregate in the expected ratio of 2: 1 . T h e expected sampling variance (Vs) of viability indices is given by the following formula (MUKAI, CHICUSA and KUSAKABE 1982; MUKAI and NACANO 1983), ( 1 ) 4n(m + n ) m3 vs = where m and n indicate the number of Cy/+ and +/+ flies emerged, respectively. Thus, environmental variance (VEN) is given by subtracting the average of the expected sampling variances (ps) of viability indices for respective replicates from the observed error variance (Gz) of viability indices anlong replicates within lines or crosses. V,N = ; vs (2) Using this formula, we estimated VEN. Estimation of the genetic variance components with respect to viability: One hundred and forty second chromosome lines were randomly chosen from 245 extracted chromosome lines in sample A. Ten sets of partial diallel crosses with seven rows and seven columns were carried out. Five Cy/+, females from the ith line (row) were crossed to five Cy/+, males from the j t h line (column) in two replicates (i = 1 7, j = 8 14). The reciprocal crosses were also made with two simultaneous replications. The experimental design is equivalent to design 11 of COMSTOCK and ROBINSON (1952) with reciprocal crosses. T h e additive and dominance variances were estimated from the components of genetic variance obtained in the analysis of variance following the procedure described by MUKAI et a l . ( 1 9

Pioneer Venus radio occultation measurements of the nightside ionosphere of Venus collected from 1979 to 1986 have made it possible to study its behavior at times of both solar maximum and solar minimum. Although some solar maximum measurements are similar in nature to those observed at solar minimum, which have an average peak density of about 7 {times} 10{sup 3} cm{sup {minus}3}, others show much higher peak densities, reaching values of about 4 {times} 10{sup 4} cm{sup {minus}3}. These elevated peak densities also occur at higher altitudes. The integrated electron column densities for these measurements are also much higher, indicating the presence of substantial ionization above the main peak. The magnitudes of both the peak density and the integrated content above the peak are anticorrelated with the solar wind dynamic pressure, leading to the interpretation that these enhancements during solar maximum are due to transterminator transport of O{sup +} ions from the dayside when the solar wind dynamic pressure is low enough to permit a sufficiently high dayside ionopause. The resulting ionization peak can be many times the concentration produced by energetic electron fluxes impacting the neutral atmosphere on the nightside, which apparently form the remaining source of the nightsidemore » peak at such times during solar maximum, when transterminator flow is cut off by high solar wind pressure depressing the dayside ionopause, and during solar minimum, when the ionopause is always depressed.« less

The rapid assay of urinary E3 using latex agglutination inhibition reaction (LAIR, E3 slide method) was evaluated.

Correlation was good between the E3 values assayed by the E3 slide method and the E3-16-glucuronide radioimmunoassay (r = 0.938) but only fair with the high performance liquid chromatography method (r = 0.851).

The E3 slide method using LAIR for semi-quantitative hormone assay takes only two minutes for each sample.

Speed, simplicity and accuracy of the E3 slide method indicate its high clinical usefulness as a prospective large scale screening test of feto-placental function.

Governments are often required to make decisions where every course available would have a negative impact on citizens, a paradox known as the 'Dirty Hands' problem. This article focusses on the political theatre around the decision by the UK Government on 12 March 2020 in relation to restricting movement of citizens during the COVID-19 pandemic. There was a stringent 'lockdown' of the population on 23 March 2020. Did the delay, estimated to have cost lives, mean the UK Government had Dirty Hands? To what extent should individuals, or the public, bear responsibility for these actions? During this phase of the pandemic, UK Government leaders communicated public health requirements in televised press briefings. These performances had enormous biopower, however at times there were discrepancies between the narratives of these performances and recommendations by public health experts. Openness with the context of an independent public health inquiry should allow a comprehensive analysis of the complex decision-making by the UK government and reveal whether the decisions involved a series of paradoxes of action that were justified.


The aim of this case report is to describe a case of atypical central serous chorioretinopathy (CSCR) definitively diagnosed after 8 years. A 44-year-old woman presented with reduced visual acuity in her left eye. Her visual acuity was light perception with projection in the right eye and 0.15 in the left. She described a similar decline in vision in her right eye 8 years ago. At that time, she had exudative retinal detachment and was treated with systemic immunosuppressive therapy for a presumed diagnosis of Vogt-Koyanagi-Harada disease. Despite resolution of the exudative retinal detachment, macular scarring developed. Eight years later, she developed inferior exudative retinal detachment in the left eye. A diagnosis of atypical CSCR was made with the help of multimodal imaging and her left eye was successfully treated with eplerenone and half-fluence photodynamic therapy (hf-PDT). In conclusion, early diagnosis and treatment of atypical CSCR may prevent subretinal fibrosis formation and permanent vision loss. Hf-PDT and eplerenone are successful treatment options for atypical CSCR.

Facing the Covid-19 pandemic, the tourism sector, especially in the hospitality sector, must make several adjustments in order to survive, one of which is reducing the number of employees. This condition causes the remaining employees to do extra work so that the company can run. This study aims to determine the role of perceived organizational support in mediating the effect of job insecurity on organizational citizenship behavior. This research was conducted at Adiwana Unagi Suites. The population in this study were 63 employees. The method of determining the sample uses the census method so that the entire population becomes the sample. Data analysis used is SEM-PLS and Sobel test. The results of this study indicate that job insecurity has a negative and significant effect on organizational citizenship behavior. Job insecurity has a negative and significant effect on perceived organizational support. Perceived organizational support has a positive and significant effect on organizational citizenship behavior. Perceived organizational support is able to mediate negatively the effect of job insecurity on organizational citizenship behavior.


Hydraulic pipeline dynamics play an important role in many real systems, for example in Diesel fuel injection, anti-skid braking, under-sea oil production and hydraulic control in general. When investigating the behaviour of such systems by simulation it is necessary to have suitable numerical models for the line. An excessively complicated model wastes computing time, but an inadequate one fails to predict the behaviour satisfactorily. A first step in deciding upon a suitable model is to look at the relationship between the frequency content of transient operations in the system and the natural frequencies of the lines. Rapid transients can be initiated by such things as valve operation, actuators reaching the end of their travel and cavitation and air release. A second important criterion is the amount of damping in the lines caused by fluid friction. This may be steady or frequency dependent friction in laminar or turbulent flow. On the one hand, increasing the complexity of the friction model employed makes the computations more involved. On the other hand, friction may limit the amount of higher frequency motion and consequently make the computations simpler. This paper examines the requirements for line models under different circumstances, and how these requirements can be met. Discussions are illustrated with results on practical systems.


The most important component is human resource in the construction industry. In Taiwan, the construction industry has a high turnover rate. According to the official statistics data, the average annual turnover rate of labor in construction industry reached up to 86.3%. It is a negative impact with a lack of human and a high turnover rate for the organization. It will not only waste human resource, but also affect the performance of construction. What happened to the manpower is therefore important to discuss. With a reasonable discussion, organizations can allocate staff positions efficiently, upgrade job satisfaction, and reduce turnover rate. Therefore, this study designed a survey for discussing the different personalities of people. After the pretest test of reliability and validity, the questionnaire is valid for surveying employees of construction industry. We used the questionnaire. The subjects were employees of construction industry from Yunlin and Taipei. 383 questionnaires were filled in and available. The data was analyzed by the statistics methods of frequency distribution, factor analysis, t-test, ANOVA, person correlation, and regression analysis. The major findings were as follows: 1. There were significant differences existed among the all variables of demographic on personality traits, job stress, job satisfaction and turnover intention except gender. 2. There were positive correlation and significant level between the factors of personal traits and job stress. 3. There were positive correlation and significant level between the factors of job stress, job satisfaction and turnover intention.


ABSTRACT This study sought to investigate the predictors of uncertainty in mothers of children with autism spectrum disorder. Sixty-seven participants were evaluated via self-reported measurements with respect to their levels of uncertainty, social support, and trust in health professionals, as well as in terms of the developmental levels and occupational performance of their children. Data regarding the mothers' educational levels and the length of time each mother had known her child's diagnoses were also collected. The results showed that the mothers' appraisal support was the best predictor of their levels of uncertainty, accounting for 22.4% of the variance in uncertainty (F(1,65) = 18.75, p < .001). Appraisal support together with both the level of trust in health professionals and educational level accounted for 36.1% of the variance in uncertainty (F(3,63) = 11.86, p < .001). These findings suggest that much of such mothers' uncertainty is preventable.

Kinchega National Park is located in semi-arid western New South Wales and like much of this sand plain country contains no local stone sources. Lithic material for tool production required transportation for a minimum distance of 40 kilometres. A recent survey of the surface archaeology has shown that many large pebbles and cobbles occur across the landscape. These are mainly of silcrete and quartzite which are also the most common raw materials represented in the flake industry. I argue that these cobbles were imported to serve as multi-function utilities, being used variously as 'portable quarries' for obtaining stone for knapping purposes, as grindstones for seed or ochre and also as anvils for breaking materials including, presumably, other stone. Possible strategies for the importation and distribution of the cobbles over the landscape are discussed. While they occur as surface material and cannot be confidently dated, it is considered most likely that their importation began during the late Pleistocene.


When the absence of organic solvents or halogenated/hydrocarbon propellants are desirable or mandatory in applying pyrethroids for typical institutional or household disinsection, emulsifiable concentrates are available that permit aqueous dilution in all proportions to provide transparent, indefinitely stable compositions suitable for non-pressurised delivery. The system is equally applicable to synergised natural pyrethrins and typical synthetic pyrethroids. The compositions can accommodate additives to provide economic residual action against crawling insects when desirable. Typical products registered in the United States will be discussed as will development activities on the new long residual pyrethroids.

done during the rest of the preceding century, with more than a dozen crews in the field during some seasons. Over 20 books were published on the subject of Arctic prehistory, again a greater number than that of all previous publications dealing with this subject. There are now more trained archaeologists doing research in the area than at any previous time, and their field research is remarkably less constrained by logistics than was that of earlier workers. Logistic and financial constraints had been an important factor in shaping the previous form of Arctic archaeology, with research areas determined largely by limited transportation facilities rather than by archaeological interests. During the late I960' s and 1970's, with scheduled airline flights available to most northern communities, the range of Inuit travel increased by the use of snowmobiles and large outboard motors, and with the establishment of facilities such as the Polar Continental Shelf Project and the Inuvik Research Laboratory, the cost and ease of Arctic archaeology became much more reasonable. At the same time, the academic boom in Canadian universities was beginning to turn out large numbers of students eager to work in new areas. The convergence of these two factors, rather than anything inherent in the archaeology of the area, led to the large amount of work which we have seen in Arctic Canada over the past decade. Perhaps the best way in which to assess the results of this work is by comparing what we knew about Arctic prehistory ten years ago with what we know about the subject today. A decade ago, the generally accepted picture of Arctic prehistory was considerably simpler and more readily understood than it is at present. The earliest occupation of Arctic Canada, aside from Indian intrusions into the southern portions of the region, was seen in the migration of Pre-Dorset people from Alaska at some time during the third millennium B.C. These people had a culture based on something like the Denbigh Flint Complex of Alaska, but their earlier history was very poorly known and generally ignored, except to note possible hints of Siberian Neolithic relationships. They were assumed to be the first archaeologically known people in Arctic North America who could be identified as "Eskimos" and, through the medium of Norton and more recent Alaskan cultures, to have been ancestral to the Eskimos of the Historic period. In Arctic Canada, the Pre-Dorset people were thought to have rapidly expanded to fill an environmental zone which was somewhat warmer and more productive than at present, occasionally spawning regional variants such as the Independence I culture of the High Arctic and the Tundra tradition of the Barren Grounds. In most regions, lack of organic and


The investigations on hydrochemisty, hydrobiology and ichthyology of Zhaling Lake and Eling Lake were carried out in June 1981 and May 1982. The salinities of the two lakes were 0.38‰ and 0.36‰ respectively. The two lakes belong to the fresh water lake of carbonate type in chemistry. 63 species of phytoplankton, 21 species of zooplankton, 20 species of benthos aod 8 species of fish were found in the two lakes. The average biomass of phytoplankton, zooplankton and benthos were 0.9 mg/l, 0.2 mg/l and 0.9g/m~2 respectively in zhaling Lake, and those in Eling Lake were 0.5 mg/l, 0.4mg/l and 1.6g/m~2 respectively. The dominant species of the prey living things were Bacillariophvta, Chrysotphyta, rotifer, copepod, larvae of Chironomidae and Oligochaeta.The authors have analysed the features of hydrochemisty, hydrobiology and ichthyology of the two lakcs meanwhile make suggestions of exploiting and ultilizating the fishery resoureses of the two lakes。

A Diophantine equation is an equation with integer coefficients, the solutions of which must be found among integers. The equation is named after the mathematician Diophantus of Alexandria (III century). Despite its simplicity, a Diophantine equation may have a nontrivial solution (several solutions) or has no solution at all. Fermat's Last Theorem and Pythagorean Theorem are the Diophantine equations too. In 1900 The German mathematician David Hilbert formulated the Tenth problem. After 70 years, the answer turned out to be negative: there is no general algorithm. Nevertheless, for some cases, schoolchildren can understand whether a Diophantine equation is solvable without resorting to calculations, relying on the methods of physics, symmetry and set theory.


Updated government guidelines for the treatment of HIV disease were published recently. Developed by 30 leading researchers, clinicians, and community advocates, "Guidelines for the Use of Antiretroviral Agents in HIV-Infected Adults and Adolescents" can help healthcare practitioners and patients in planning the course of HIV treatment. The new guidelines include a recommendation that abacavir (Ziagen), the newly approved nucleoside analog reverse transcriptase inhibitor, be listed as an alternative treatment, not a preferred one. The Guidelines also discuss the use of hydroxyurea. The internet address, where the full report can be found, is provided. Information is also provided for ordering a print copy of the guidelines or listening to a recording of discussion groups concerning the Guidelines.


[Objective] To study the drought resistance of four introduced sugarcane varieties such as GT02-208.[Method] With 4 introduction varieties such as XDY7,XDY11,XDY12,GT02-208 and two check varieties such as ROC22(strong drought resistance) and ROC16(less drought resistance) as tested materials,compared with normal water supply,the effects of drought stress on physiological indexes,yield characters and process quality of sugarcane based on the potted experiment and the control of water in elongation period were researched,and then membership function of fuzzy mathematics was used to judge the drought resistance of sugarcane varieties.[Result] The membrane permeability,MDA content,proline content of leaf increased significantly under drought stress.The increases were not same in different varieties.Drought stress led to shorter plant and lower production in the later stage of elongation.Drought stress also led to the maturity delay,the sucrose decline,the reducing sugars increase,and made the Process quality become deterioration.[Conclusion] According to the calculated results of membership function,the drought resistance value order of varieties was: ROC22 XDY11 XDY7 XDY12 ROC16 GT02-208.


In this paper, substrate integrated waveguide (SIW) filters with multilayer configuration are presented. Such configurations reduce circuit footprint area without compromising the passband loss. Here it is shown that a metallic post can provide magnetic as well as electric coupling. Further, it is shown that proper placement of the slots, used here to obtain coupling between two adjacent layers, can provide next harmonic suppression. Finally, a four-pole prototype is designed which provides symmetrically placed transmission zeros. The filter offers a measured insertion loss of 1.55 dB at $\boldsymbol{f}_{0}=2.20$ GHz. The stopband rejections are at least 40 dB at $(\boldsymbol{f}_{0}\pm 0.2)$ GHz and the next harmonic is suppressed at least by 28 dB.


In this work we introduce the possibility of unparticle mediated superconductivity. We discuss a theoretical scenario where it can emerge and show that a superconducting state is allowed by deriving and solving the gap equation for s-wave pairing of electrons interacting through the unparticle generalization of the Coulomb interaction. The dependence of the gap equation on the unparticle energy scale Λ U ?> and the unparticle scaling dimension dU enables us to find a richer set of solutions compared to those of the conventional Bardeen–Cooper–Schrieffer paradigm. We discuss unconventional features within this construction, including the resulting insensitivity of pairing to the density of states at the Fermi energy for d U = 3 / 2 ?> of the superconducting gap and suggest possible experimental scenarios for this mechanism.


Abstract : The report presents the results of four male adult subjects exposed to sensory isolation through water-immersion for three trials totaling about 20 hours. The results presented are EKG frequencies taken before and after time-estimation hacks throughout the runs. EKG frequency taken before time hacks showed a decrease across trials; that taken after time hacks displayed a rather steady picture. These results were viewed as evidence for the notion that stress arousal may be ameliorated with experience while arousability may remain at the same level. (Author)


Human sleep is divided into two segments, Rapid Eye Movement (REM) sleep and Non-REM (NREM) sleep. NREM sleep is further divided into 4 stages. Sleep staging attempts to identify these stages based on the signals collected in PSG. Significant information can be derived from the EEG signals collected during PSG. Wavelet coefficients are extracted from EEG signals. In order to reduce the amount of data set, the statistical features are calculated from wavelet coefficients. For performing decision making, six ANFIS classifiers and SVM classifier are used to differentiate between REM and Non-REM sleep stages. That is to say, pattern varies under the different sleep stages. Therefore, healthy humans with a regular night's sleep will follow these sleep stages in a particular pattern.

The interest of education in general and higher education in particular was the main reason of the advancement of many developing countries. The provision of the appropriate educational environment is the most important component of the improvement of the educational process and its goal of creating an educated generation through the construction of suitable buildings,and giving more attention on the main space, which is the classrooms.This interest stems mainly from the famous saying of Winston Churchill: (We shape our cities, and then theyshape us),sothe decision maker must know what to take in consideration in order to achieve the required classrooms which its efficiency is reflected on the quality of higher education outputs. Hence, the idea of this research is to study the assessment of the educational environment in the classrooms in the university buildings


Aquaculture in Malawi is relatively undeveloped, dominated by smallholder farmers (SHFs) who are largely non-market oriented and semi-commercial, yet facing numerous challenges that lead to low productivity. The use of poor-quality feed, scarcity of fingerlings, limited technical and business skills, lack of financial services, low interest among investors, environmental and climate change risks – all these factors frustrate the sector's growth for global competitiveness. This brief engages potential investors, government and SHFs as part of the transformation process of the sector.


Abstract Nuclear small subunit ribosomal RNA (18S rRNA) gene sequences were determined for six species representing three genera classified within the Mastophoroideae, and also for two species of Amphiroa (Lithophylloideae). These data were combined with previously published 18S rRNA sequences for 38 other coralline species and analysed (1) to determine the phylogenetic position of the Mastophoroideae within the Corallinaceae and (2) to examine relationships among Hydrolithon, Metamastophora, Neogoniolithon and Spongites. Trees derived from parsimony and maximum likelihood analyses of these data indicate that the Mastophoroideae is not monophyletic. Instead, our data suggest that the group is polyphyletic and includes species belonging to four distinct evolutionary lineages. For example, Neogoniolithon spp. were associated with geniculate members of the Corallinoideae, and Hydrolithon was resolved as sister to the geniculate genus Metagoniolithon. We demonstrate that each of the four 'mastophoroid' lineages share a number of vegetative and reproductive features with their respective sister taxa. Together the molecular and morphological data imply that the Mastophoroideae is not monophyletic and that genera placed in this taxon might more naturally be classified in other subfamilies. Also, on the basis of our findings, Porolithon pachydermum is transferred to Hydrolithon as H. pachydermum (Foslie) Bailey, Gabel & Freshwater.


It has always seemed to me that of all the problems which are presented in the practice of medicine those cotlcerning the general invasions are by far the most interesting. Discounting the bias which may naturally be ascribed to me, I nevertheless believe that the problems of the general invasions of otitic origin are second to none in their interest. The subject concerning which I have the privilege of addressing you this evening has many ramifications. I might say that for a number of years I have been concerned chiefly with the practical side of it.

Resistive switching memory devices, in which the resistance can be modulated between two nonvolatile states by applying an electrical pulse, have been proposed as the fascinating candidates for next generation logic and nonvolatile memory devices. Herein we report on the observation of magnetic-field controlled resistive switching behaviors in the Ag/[BiFeO3/γ-Fe2O3]/FTO structure. Moreover, this resistive switching behavior can be modulated by white light. Therefore, such a resistive switching memory can be controlled simultaneously by voltage pulses, magnetic field and white light. This study is helpful for exploring the nonvolatile multistate memory devices manipulated by various means.

This paper reports on an action research project that aimed to explore ways to support international ESL students undertaking Information Systems courses at an Australian university. Using a range of data sets including students' grades, students' evaluations, tutors' evaluations, results from a student focus group, and an interview with collaborating teaching staff, the paper concludes that the main initiative implemented during the research, providing team-taught support tutorials to identified students, was highly beneficial, both in terms of student and staff perceptions and in terms of learning outcomes (for each support tutorial attended, students achieved an increase of 2.2 per cent in their overall mark for the course). However, significant institutional support is necessary, if the recommendation of the research, that support tutorials for core courses are timetabled for all international ESL students in their first year of study at an Australian university, is to be implemented.


Under loss-of-coolant accident conditions, there is a possibility that noncondensible gas (i.e., nitrogen, hydrogen, or fission gas) will enter the primary system, which can adversely affect the capability to remove decay heat. Small- and medium-sized breaks cause depressurization and lead to release of N{sub 2} dissolved in the primary coolant and accumulator inventories. Failure to close of an accumulator isolation valve after the accumulator content has emptied into the primary can result in significant amounts of propellant gas entering the primary system. In the event of a total loss of on- and off-site power, the feedwater is also lost. With the main steam isolation valves close, the secondaries boil dry through relief valves. The core decay heat leads to pressurization of the primary system, opening of the pressurizer safety relief valve, and loss of primary inventory. Without operator intervention, this scenario results in core uncovery and core damage as the primary inventory is depleted. At temperatures >800{degree}C (1500{degree}F), zircon/water reaction will take place accompanied by formation of substantial amounts of hydrogen. At this stage, even restored heat transfer (e.g., resumption of feedwater flow) will be impeded by the presence of the hydrogen. The influence of noncondensible gases on the heatmore » transfer capability of a four-loop pressurized water reactor (PWR) was investigated in several parametric studies carried out in the PKL test facility.« less


THROUGHOUT medical history there has always been a tendency to repeat the statements of the "authorities" without criticism. Probably nothing has retarded medical progress more. The tendency has been particularly marked in therapeutics, and even today, when this should be based on physiological pharmacology, the old traditional remedies are being prescribed, even when it is known that the agent prescribed is inert, ineffective or even harmful. For example, babies are put into mustard baths for convulsions, and gargles are prescribed for sore throats, although we know that no gargle passes beyond the anterior faucial pillars.


A rapid and cost effective method for nanostructure fabrication in a large area was proposed in this paper. The integration of conventional ultra-violate lithography and self-developed technique was adopted to fabricate 700 nm nanocasts. Polydimethysiloxane (PDMS) was used to be a flexible mold material for the 2-inch wafer area uniform imprinted structures. This rapid structure fabrication technique can be applied to commercialized light emitting diode as a texturing surface to raise the light extraction efficiency significantly.


The gut microbiome impacts host gene expression not only in the colon, but also at distal sites including liver, white adipose tissue, and spleen. The gut microbiome also influences the kidney and is associated with renal diseases and pathologies; however, a role for the gut microbiome to modulate renal gene expression has not been examined. To determine if microbes modulate renal gene expression, we used whole-organ RNA sequencing (RNA-Seq) to compare gene expression in C57Bl/6 mice that are germ-free (lacking gut microbiota) versus conventionalized (with gut microbiota). 16S sequencing showed that males and females were similarly conventionalized, although Verrucomicrobia was higher in male mice. We find that renal gene expression is differentially regulated in the presence versus absence of microbiota, and that these changes are largely sex-specific. Although microbes also influence gene expression in the liver and large intestine, most differentially expressed genes (DEGs) in the kidney are not similarly regulated in the liver or large intestine. This demonstrates that the influence of the gut microbiota on gene expression is tissue specific. However, a minority of genes (n=4 in males, n=6 in females) were similarly regulated in all three tissues examined, including genes associated with circadian rhythm (Per1 in males and Per2 in females) and metal binding (Mt1 and Mt2 in both males and females). Finally, using a previously published single cell RNA-Seq (scRNA-Seq) dataset, we assigned a subset of DEGs to specific kidney cell types, revealing clustering of DEGs by cell type and/or sex. NEW & NOTEWORTHY It is unknown whether the microbiome influences host gene expression in the kidney. Here, we utilize an unbiased, bulk RNA-Seq approach to compare gene expression in the kidneys of male and female mice with or without gut microbiota, as well as in liver and large intestine. This report demonstrates that renal gene expression is modulated by the microbiome in a sex- and tissue-specific manner.

Reorganization energy is one of the important factors to decide the rate of electron transfer according to the Marcus theory. Small reorganization energy is highly desirable in design of optoelectronic and electronic devices like as organic light emitting diode. For this reason, reorganization energy of aromatic diamine derivatives, N,N′-diphenyl-N,N′-bis(3-methylphenyl)- (1,1′-biphenyl)-4,4′-diamine (TPD) and 4,4′-diphenyl-N,N,N′,N′-tetraphenylbenzidine (DTPB) have been studied theoretically by self-exchange electron transfer theory. By executing the Gaussian 03 calculation we can easily figure out the optimization point which needed for calculation of the inner reorganization energy (λ) of self-exchange electron transfer reaction. Also ionization potential and electron affinities of these molecules can be calculated at the density functional theory level with basis set 6-31G** and 6-31G* using Gaussian 03 software on the basis of ab initio method. It gives possibility to develop a semi-empirical model for the observed absorption and photoluminescence spectrum.


The paper investigates the effects of ethnic diversity on economic performance and the risk of violent conflict. Diversity has various detrimental microeconomic effects, tending to reduce public sector performance, increase patronage, and lower the level of trust among individuals. However, whether diversity adversely affects overall economic growth depends upon the political environment. Diversity is highly damaging to growth in the context of limited political rights, but is not damaging in democracies. The same relationship holds for the satisfactory performance of World Bank projects: in diverse societies, the risk of project failure is nearly doubled by the absence of political rights. There is a relationship between ethnic diversity and the risk of violent conflict, but it is non-monotonic. Those societies most at risk are the ones in the middle of the range of ethnic diversity. Highly diverse societies, such as are typical of Africa, are actually even safer than homogenous societies. A democratic Africa can thus reap the benefits which ethnic diversity provides in terms of a reduced risk of violence, while avoiding the potential costs of reduced growth. Both income levels and political rights are also important influences on the risk of violent conflict, and of its escalation into full civil war. Once a society has reached full scale civil war the balance of influences appears to change. The persistence of conflict, and the sustainability of a settlement, are more dependent upon ethnic composition and less dependent upon income and political rights, than are the initiation and escalation of violence. Hence, some peace settlements may need to change borders so as to increase (or reduce) the ethnic diversity of the state.

Abstract : Radiation from rocket exhaust plumes in the vacuum ultraviolet (VUV) spectral region (110-180 nm) is of considerable importance to The Air Force and the Defense Research Projects Agency. However, before emission features in a given spectral region can be used by systems, a target model relating radiation intensity to characteristic missle parameters such as fuel type, altitude, area ratio, etc., must be developed. Intensity measurements on the systems of interest are the best source of such a model, but since radiation from foreign missiles generally cannot be measured under controlled conditions, theoretical means using laboratory results must be employed. As part of such an approach, the authors have identified the radiation, and determined the mechanism leading to emission, from a number of laboratory mixtures corresponding to major reactant compositions found in plumes of hydrocarbon- and amine-fueled rockets. These laboratory reaction systems are atomic O/C2H2 and atomic O/atomic N/C-compound mixtures in a fast-flow tube reactor at 300 K and 0.8 to 10 Torr and self-sustaining flames of various hydrocarbon and amine fuels with O2 and N2O4 at 1700-2200 K and 0.8 - 20 Torr.

Background: There is a lack of research to evaluate the effectiveness of Chinese Herbal Medicine (CHM) as an adjunct therapy in patients with advanced Non-Small Cell Lung Cancer (NSCLC). Objective: The main objective of this study was to assess whether the advanced NSCLC patients treated by Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors (EGFR-TKIs), when combined with CHM, can improve the five-year survival rate compared to those treated by EGFR-TKIs alone. Methods: A nationwide population-based study of advanced NSCLC patients receiving EGRF-TKIs, combined with or without CHM treatment, was conducted in Taiwan. The study is based on information in the sub-dataset of the National Health Insurance Research Database (NHIRD) from 2000 to 2010, during which time a total of 14,244 patients were diagnosed with NSCLC. After selection of exclusion criteria and matching process, 2,616 NSCLC patients were included in the study. Statistical analysis was utilized to evaluate the differences in characteristic distribution, and to compare the survival rates between the CHM cohort and non-CHM cohort. Results: Patients with advanced NSCLC using CHM as an adjunct therapy exhibited a significantly improved survival rate [Hazard Ration (HR) =0.8; 95% Confidence Interval (CI): 0.73-0.87, p value<0.001], compared with non-CHM users. Based on a survival analysis by Kaplan-Meier method, the 5-year survival rate of CHM users increased 4.9%, with the most notable difference being an increase of the 2-year survival rate by up to 12.75%. In addition to survival rate analysis, we provide the ten most used single herbs and herbal formulas prescribed for patients with advanced NSCLC. Conclusions: This nationwide retrospective cohort study provides evidence supporting CHM as an effective adjunct modality to ameliorate the side effects of target therapy and prolong the five-year survival rate of patients with advanced NSCLC.


The electrical resistivity of compacts of glass and nickel spheres has been correlated with bulk density during hot-pressing. Conductivity, based on deformation of spheres into several geometric shapes under hot-pressing conditions, is described by σm/σc=α (D2/3β2/3R2— 1), where σm and σc are the conductivities of a compact of spheres at relative density D and theoretical density (D= 1), respectively; α and β are constants depending on geometry; and R is the radius of the deformed sphere.
