In this paper, we report on a low-voltage-operation n-type organic thin film transistor (OTFT) and a complementary inverter circuit using a thiazolothiazole derivative as an organic semiconductor (OSC). To achieve the low voltage and stable operation of the n-type OTFT, a bilayer structure consisting of a thin low-k polymer layer and a high-k Ta2O5 layer was used and investigated as the gate insulator. Atomic force microscopy images of the OSC film on the hydrophobic polymer showed densely distributed small grains, and the corresponding OTFT exhibited hysteresis-free and excellent n-type performance, for example, an electron mobility of 0.23–0.35 cm2 V-1 s-1. In addition, the n-type OTFT with a thinner polymer layer exhibited a low operating voltage of less than 10 V while maintaining excellent characteristics. A complementary inverter based on the thiazolothiazole derivative and pentacene was also fabricated using the bilayer gate insulator. The switching operation of the inverter was achieved at a low voltage of 5–10 V.


Abstract€–€The€objective of this work was to compare the growth and the competitive ability of two crabgrass( Digitaria ciliaris ) biotypes, one resistant (R) and other susceptible (S) to the acetyl coenzyme A carboxylaseinhibiting herbicides. Biotypes growth was determined by collecting the plant dry mass at 14, 21, 25, 28, 34, 42, 49,57, 65, 72, 78, 86, 101, 111, and 118€days after emergence (DAE). Data of dry mass were adjusted to a logisticmodel, and were also used to calculate the absolute growth rate. Five experiments were installed to evaluate theintraspecific and interspecific competitive ability, using the substitutive method. The biotypes R and S werecompared between themselves and each one of them with the soybean crop seeded in the same day or sevendays after the seeding of the weeds. Plant proportions between species or biotypes used were: 5:0; 4:1; 3:2; 2:3;1:4, and 0:5. The biotypes presented similar dry mass accumulation, absolute growth rate and interspecificcompetition, and the reduction of soybean mass was similar in the presence of R and S crabgrass biotypes, whichsuggests that R and S crabgrass biotypes have the same ecological adaptability.Index term:


Commentary on : van Dalem J, Brouwers MC, Stehouwer CD, et al. Risk of hypoglycaemia in users of sulphonylureas compared with metformin in relation to renal function and sulphonylurea metabolite group: population based cohort study. BMJ 2016;354:i3625.

Type 2 diabetes mellitus (T2DM) is one of the most serious health problems worldwide.1 Strict glycaemic control has been emphasised, and the number of patients with the risk of hypoglycaemia has increased.2 Hypoglycaemia is a serious side effect of treatment with sulphonylureas, which stimulate insulin secretion regardless of blood glucose level. It is more common in patients using long-acting sulphonylureas with renally excreted active metabolites.3 Therefore, an increasing number of patients with renal impairment may currently live with the risk of hypoglycaemia. …


The ready accessibility of (R)-α-aminoadipic acid by enzymatic cleavage of cephalosporin C (CephC) in the production of 7-aminocephalosporanic acid (7-ACA) on a large scale makes it a favorable chiral pool building block for the synthesis of unusual amino acids. A route for the synthesis of C-5-alkenyl and C-6-alkylidene derivatives of (R)-pipecolic acid is described which utilizes (R)-α-aminoadipic acid as the enantiomerically pure starting material. Moreover, the synthesis of azido and triazolyl derivatives of (R)-α-aminoadipic acid is reported.


Identification of the strength of relationship between two variables is usually done by the investigation of their correlation coefficient. For determining the strength of linear relationships usually Pearson's correlation coefficient is used that requires the variables to be normally distributed. However, presence of outliers and even minor deviations in the underlying distribution from the Gaussian can lead researchers and practitioners astray when interpreting the results. Since detection of multidimensional outliers is not always feasible and our data sample does not necessarily shows normal distribution in practice and furthermore correlation analysis is a fundamental step for selecting variables for various statistical analysis a robustified correlation measure is advised to be calculated alongside conventional Pearson's correlation coefficient. In this study we apply the Most Frequent Value (MFV) robustified correlation coefficient for investigating the speed of convergence in economic growth among NUTS regions of the European Union, where from theory linear relationship is assumed but the corresponding available data are not normally distributed and may contain outliers.

The installation of gas‐filled diffusion samplers into small‐diameter boreholes results in a significant reduction of the dissolved gas concentration around the sampler. In aquifers where the diffusive flux of solutes outpaces advective transport, the process that governs the equilibration time of a sampler is the resupply of solutes by diffusion from the aquifer. We have derived a solution that can be used to estimate the time required for a diffusion sampler to reach equilibrium with the dissolved gas concentration in the aquifer, where diffusion is the only solute transport mechanism. Thus the solutions provide equilibration times for cells placed in aquifers where diffusion dominates and maximum equilibration times for cells placed in aquifers where advection can also resupply solutes. The solutions are generic and are functions of nondimensionalized variables, therefore providing estimates of equilibration times for any type of solute, sampler volume, bore dimensions, and aquifer porosity. Examples are given for various sized gas‐filled helium samplers placed in boreholes of different radii.


Changes in the magnetic field allow us to probe the Earth's iron core. Grace Cox and William Brown review how observations, modelling and theory combine.


A theoretical analysis is presented of heat engines that use the atmosphere as a hot reservoir and a cryogenic medium as a cold reservoir. These "cryogenic" heat engines can be used as zero emission power sources and are found to have unexpectedly large specific work (work per unit mass of the cold reservoir) values when gases of low atomic mass are used as the cryogenic medium.

Few studies have recorded the spectral signatures of domesticated live animals and in particular few have examined wild species. Using in situ radiometry we acquired visual and near infrared spectral signatures of wild elk (Cervus elaphus) and domesticated cattle (Bos taurus) and horses (Equus caballus). Signatures were significantly different among species across all bands with the exception of cattle and horses in the red band. Further research is needed to determine if the shallower slopes in the red-shift region of the animal signatures would allow for distinction from vegetation using various remote sensors. Application of in situ spectral signatures to remotely sensed imagery could provide an efficient method for counting wildlife.

We now face a potential second wave of the covid-19 pandemic and a backlog of elective work, and it is critical to avoid overcrowding and pressure on beds to prevent cross infection and further cancellation of services. Whose job is it to decide when patients are ready to leave hospital, with their families and community services able to support them? Recent guidance from NHS England on hospital discharge for all NHS trusts and social care staff goes further than ever.1

The government has provided an additional £588m (€640m; $750m) funding, via the NHS, to help cover the cost of recovery and support services, rehabilitation, and care for up to six weeks after patients' discharge from hospital. In return, it expects action to help keep hospital beds free for patients with the most pressing needs. The new guidance revolves around a "discharge to assess model" that channels patients who leave hospital into four indicative pathways. It also requires eligibility and financial assessments for social and NHS care continuing to …


Abstract : Two different constructive techniques for approximating positive definite functions by means of finite exponential sums are explored. One technique constructs the coefficients and the exponents. The other technique constructs the exponents when the coefficients are all required to be equal. Both approximation techniques appear to be suitable for numerical computation. The techniques extend to completely monotonic functions as well. Error bounds are proved using elementary methods. In an application, these error bound can be used to eliminate some of the effort and guesswork previously necessary in two procedures for the design and synthesis of sparse broadband linear arrays.

U.S. policy in Latin America, even when couched in the openly diplomatic discourse used by the Obama administration, is based on military presence and serves the economic interests of the United States and allied Latin American elites. In order to secure the free-market context that ensures U.S. access to Latin America's strategic resources, U.S. administrations have focused on issues such as security and the fight against narco-insurgency and terrorism, encouraging and directly supporting Latin American regimes in which increased military presence in the government is purported to guarantee internal stability during a time of increasing violence. In reality, what they foster is a complex balance between stability and instability that maintains the region's overall dependence and, therefore, its status as a source of U.S. wealth and power.

Objective. To assess a role of pulmonary microvascular thrombosis in the development of acute lung lesion. Material and methods. Experiments were carried out on 60 albino non-inbred male rats. Thromboplastin solution was injected into their jugular vein under anesthesia. Experiments lasted 1 hour to 3 days. Lung specimens were fixed in 10% neutral formaldehyde solution and poured into paraffin. Histological slices were stained with hema-toxylin-eosin; periodic acid Schiff reaction was made. Morphometrical and statistical studies were employed. Results. 1—3 hours after thromboplastin injection, there were thromboses in the lumens of minor arteries, capillaries, and veins, developed interstitial and intraalveolar edema, and diapedetic hemorrhages, epithelial desquamation into the bronchial lumen, as well as stab leukocytic infiltration of interalveolar septa. The magnitude of morphological changes in the lung is dissimilar in different animals. Conclusion. Pulmonary microvascular thrombosis leads to the development of acute lung lesion documented by morphological studies.


In this study, a novel method for image recognition based on deep learning algorithm and image denoising is proposed. It is based on Bernoulli process factor analysis denoising method and tiled convolutional neural network. The images are first denoised using Bernoulli process factor analysis, and then the denoised images are transmitted to tiled convolutional neural network for robust feature extraction. Lastly, support vector machine is used for classification. The experiments implemented on the benchmark dataset CIFAR-10 shows the effectiveness of our proposed method, which performs better than our previously proposed method, CDAE-SVM (contractive denoising autoencoder + SVM).

The social inclusion of migrant workers is the major problem in the development of city.From the social interaction perspective,there is an obvious involution feature in the city life of migrant workers,including the polite interaction behavior,the broad friend relations and the limited community participation.To resolve this problem and promote the social inclusion of migrant workers,we need to keep an open attitude in the community,to create social conditions and opportunities for migrant workers and to adjust the community management system.


In this paper, we propose a simple but effective tone mapping operator, which can achieve impressive results with low complexity in both the formulation and computation. The key point of our operator is to calculate a scalar matrix by which the input HDR image can be mapped into a displayable LDR image. From the graphical perspective, we can regard the scalar matrix as a guided image, as shown in Figure 1(b). Experimental results show that our algorithm can achieve real-time perceptually pleasing result.


To the Editor:

The article by Zaharchuk et al1 raises a series of questions.

First, the authors are careful to delineate many problems concerning interpretation of data gathered with the BOLD technique and the variations they employ. These limitations might help explain some of the difference between the microvascular versus the global cerebral blood volume changes they observe during hypoperfusion. However, the authors never call our attention to a much more glaring problem: In their Figure 3, there is no decrease in either total cerebral blood volume (CBV) or microvascular volume over the whole autoregulatory "plateau." This is impossible. There must be an increase in resistance—a decrease in diameter—somewhere to account for the good autoregulation over the plateau. Until we have a reasonable explanation for their finding, it seems premature to trust their techniques and accept their conclusion that "CBV changes during hemorrhagic hypotension are far less than … [those] … reported by some previous studies."

Second, the authors talk about cessation of autoregulation as the pressure falls below the so-called lower limit of autoregulation. This way of expressing matters is the one usually used, but it is highly misleading. Beyond each end of the "plateau" the vessels continue to autoregulate—ie, to relax as pressure falls and to constrict as pressure rises. Thus, the resistance continues to go up at pressure above the high end of the "plateau" and to fall at pressure below the low end. However, these autoregulatory changes in tone are no longer sufficiently larger to compensate for the changes in pressure, and the flow changes more markedly for each change in pressure than it did for …


The photochemical reaction of 9,10-diazaphenanthrene (DAP) was investigated in the acidic aqueous 2-propanol under nitrogen. It has been found that with ultraviolet irradiation (366 nm) DAP changes into carbazole. On the other hand, it was deduced that 2,2′-diaminobiphenyl was produced with visible light irradiation.

The government's management functions affect the development of MOOC This paper provides a reference for improving information technology by reviewing China's MOOC and current status issues, and guiding domestic MOOC information technology and government management.


The composite system of 4-bromine-1,8-naphthalene-imide and CdS nanometer particles were prepared by chemical method,and the influence on each other was studied by UV-visible absorption and fluorescence spectrum.After CdS nanometer particles were surface-coated by 4-bromine-1,8-naphthalene-imide,the absorption peak of their composite bodies moved from 348.28 nm to 349.79 nm,and the intensity is obviously increased.At the same excitation(360 nm),its profile of absorption spectrum is the same,but fluorescence peak is red shift from 394.51 nm to 394.83 nm and intensity descends a little.The fluorescence peak of 4-bromine-1,8-naphthalene-imide is at 570.55 nm by 400 nm excitation.At the 330 nm excitation,the fluorescence peak of the composite system is at 499.66 nm.At the same time,the fluorescence intensity of the composite body has obviously increased.


The hyporheic zone is the ecotone between stream and river channel flow and groundwater that can process nutrients and improve water quality. Transient hyporheic zones occur in the riparian zone (bank storage or "lung model" exchange) during channel stage fluctuations. Recent studies show that soil pipes are widespread in stream banks and beneath floodplains, creating highly preferential flow between channel and riparian groundwater such that the traditional Darcy model of flow does not apply. We used MODFLOW with the conduit flow package to model a series of stream bank soil pipes and examined soil pipe density (number per m), length, diameter, height above baseflow water surface, connectivity, and matrix hydraulic conductivity on transient particle flow paths and total hyporheic exchange volume (i.e., bank storage) over the course of a peak flow (e.g., storm) event. We found that adding five soil pipes per meter more than doubled hyporheic volume. Soil pipe length was the most important control; adding one 1.5‐m‐long soil pipe caused a 73.4% increase in hyporheic volume. The effect of increasing soil pipe diameter on hyporheic volume leveled off at ~1 cm, as flow limitation switched from pipe flow to pipe‐matrix exchange. To validate our approach, we used the model to successfully reproduce trends from field studies. Our results highlight the need to consider soil pipes when modeling, monitoring, or managing bank storage, floodplain connectivity, or hyporheic exchange.


Particle motion in the secularly varying geomagnetic field is investigated in terms of a dipolar magnetic field with decreasing magnetic moment M. For dM/dt equal to the rate of decay of the earth's dipole component, we find there is drift in B-L space, resulting in an inward drift of particles accompanied with increased energy and unidirectional intensity. Secular variation of the geomagnetic field appears to be a dominant mechanism for radial drift in the inner radiation belt.


Abstract : Acetylene terminated sulfone resin (ATS), hereafter designated as ATS-G, and components of that resin mixture isolated by column chromatography, were exposed to elevated temperatures in the presence of oxygen to determine and compare oxidative stabilities. Degradation in the presence of an unlimited supply of oxygen was simulated by programmed thermogravimetry, and under partially anaerobic conditions. It was found by thermogravimetry (TGA) that although oxygen does not appear to be incorporated to any measurable extent into ATS polymers cured in air, those polymers became slightly less resistant to high temperature oxidative degradation than their counterparts cured under nitrogen. In other experiments, it was shown that direct attack of oxygen on ATS resins, at least under the conditions of the TGA experiment, takes place only after completion of those thermal degradation reactions producing oligomeric and condensable volatile products of degradation. In other words, the stability of those resins to oxidation under the accelerative conditions of the TGA experiment is proportional to their thermal stability.

A numerical method for solving a reaction -diffusion Partial Differential Equations (PDEs) in irregular domains with spatial boundary conditions in 2D and 3D is proposed. The idea of the proposed method is to embed the given irregular domain in a cell type domain and to constitute a new PDE, with Dirichlet boundary conditions, using a particular auxiliary function that permits to determine the solution of the new problem such that satisfies the equations of the main problem on initial irregular domain. Several examples of PDE in 2D and 3D are examined. The results show the performance and efficiency of proposed method. MSC: 65M70 • 65T50


An empirical determination of traffic signal visibility is presented. The study used subjects seated in stationary vehicles viewing standard, full-sized traffic-control signals at distances ranging from 370 to 1300 ft. Data, including response accuracy and response latency, were collected for both day and night ambient lighting conditions. It was found that currently used circular traffic-signal indications are generally adequate for nighttime service but their adequacy for daytime conditions is suspect. Signal visibility was found to be somewhat insensitive to signal lens size and illumination intensity for nighttime operations, which implies that even the dimmest signal tested (8-in lens with 67-W bulb) is above threshold visibility for all distances at night. The single most important factor affecting the visibility of traffic signals during the day is signal color. Green indications generally led to the poorest subject response, in terms of both response accuracy and response time, for the daytime observations. In relation to visibility considerations alone, the data obtained present strong support for the possibility of dimming all colors of 12-in signal indications at night. (Author)


O ne of the most striking characteristics of the contemporary American West is the number and variety of ethnic minority group members who make it their home. There has been a steady growth of migrant and immigrant populations in the western states for more than a century. While the overall US population is rapidly expanding, growing by 6% between 1970 and 1980, the West has increased at an even more rapid rate. Rates of growth for individual states range from a low of 13.3% in Montana to a high of 63.5% in Nevada.' During the 1970s, furthermore, the number of minority group members increased at a much more rapid rate than did the US population generally. Blacks grew by 17.3%, Native Americans and Hispanics* by even more, and the number of Asian and Pacific Island peoples more than doubled in the tenyear period.2 With the exception of blacks, all major ethnic groups are heavily overrepresented in the West (See Table 1). For example, in 1980 42.8% of all Hispanics, 50.7% of Native Americans, 52.7% of Chinese-Americans, 69.3% of Pilipino-Americanst and 80.6% of Japanese-Americans lived in the western states. Many western US cities contain many tens of thousands of immigrants from every major part of the world. For example, it is estimated that since 1970, 2 million foreign immigrants have settled in the Los Angeles area alone, more than 90,000 of them during the single year of 1982. According to one report, "of L.A.'s 550,000 schoolchildren, 117,000 speak one of 104 languages better than they do English" (Time, June 13, 1983, p 20). With such numbers and such proportions, it is impossible for physicians and other health professionals to ignore the special problems and needs of patients from these communities. These problems are of several kinds: First, many immigrant and refugee populations have higher rates of infectious disease and parasitic


This paper, based on the transformation and development of applied English majors in vocational undergraduate education, is intended to construct machine translation post-editing training rooms by analyzing the language industry development status, foreign languages majors' competence adaptability for enterprises requirements, and the connotation of machine translation post-editing training with a view to provide suggestions and references for the construction of applied English practical courses.


The major organic component in carbonaceous meteorites is an organic macromolecular material. The Murchison macromolecular material comprises aromatic units connected by aliphatic and heteroatom-containing linkages or occluded within the wider structure. The macromolecular material source environment remains elusive. Tradi-tionally, attempts to determine source have strived to identify a single environment. Here, we apply a highly efficient hydrogenolysis method to liberate units from the macromolecular material and use mass spectrometric techniques to determine their chemical structures and individual stable carbon isotope ratios. We confirm that the macromolecular material comprises a labile fraction with small aromatic units enriched in 13 C and a refractory fraction made up of large aromatic units depleted in 13 C. Our findings suggest that the macromolecular material may be derived from at least two separate environments. Compound-specific carbon isotope trends for aromatic compounds with carbon number may reflect mixing of the two sources. The story of the quantitatively dominant macromolecular material in meteorites appears to be made up of more than one chapter. The stable carbon isotopic composition of proposed fractions obtained by mass balance measurements (Sephton et al. , 2003) are presented alongside corresponding structures and compound-specific isotope data for hydropyrolysis products from this study.


After an uncomplicated birth and initial symptom-free period, a 7-day-old male infant presented with poor feeding, hypotension, hyponatremia (123 mmol/L; reference interval, 135–148), hyperkalemia (9.0 mmol/L; reference interval, 3.5–5.5), and increased blood urea nitrogen. A diagnosis of primary adrenal insufficiency was made following an adrenal ultrasound remarkable for no discernable adrenal tissue. Subsequent fluorescent in situ hybridization studies revealed deletions in the region containing the NR0B1 ,5 IL1RAPL1 , and GK genes in both the patient (for which he was treated with adrenocorticosteroids) and his asymptomatic mother. At approximately 4 years of age, he experienced a hypoglycemic episode (plasma glucose, 42 mg/dL). Fasting triglyceride level was also increased at 465 mg/dL (reference interval, <250). Approximately 1 year later, he presented again to the emergency room with vomiting, headaches, lethargy, cramps, and diarrhea. Clinical examination showed a developmentally delayed child with hypotonia and strabismus. He had iatrogenic Cushing syndrome. There was evidence of microorchidism, meatal stenosis, congenital hydroceles, and bilateral inguinal hernia. As part of follow-up studies, an array comparative genomic hybridization was performed. A urine specimen was also collected for organic acid analysis using GC-MS (Fig. 1).

The GPU usually handles the homogenous data parallel work, by taking advantage of its massive number of cores. In most of the applications, we use CUDA programming for utilizing the power of GPU. In data intensive high computational applications like neural networks, utilizing the GPU on a single machine is time consuming. Instead if multiple GPUs are used in a network the amount of time required will be significantly reduced. Traditionally to enable a set of program to be run in a distributed environment, programmer has to accordingly design components to make his system dynamic and resilient to changes in number of systems in cluster, which is a daunting task. This work distribution can be a poor solution as it may underutilize the GPUsIn our approach, we developed a framework which transparently distributes data parallel kernels across multiple GPUs in a distributed network. The programmer is responsible for developing a single data parallel kernel in CUDA while the framework automatically distributes the workload across an arbitrary set of CUDA enabled GPUs. Depending on current workload on GPUs and the amount of data to be processed optimal distribution is done. The goal is to maximally utilize the available resources with minimal programming complexity. The systems not compatible with CUDA can also utilize our solution. We expect our framework to reduce the processing time along with simplifying the task of programmers.


This paper derives a closed-form solution for European options on pure discount bonds, assuming a mean-reverting Gaussian interest rate model as in Vasicek [8]. The formula is extended to European options on discount bond portfolios.


Secondary electron microscopy (SEM), Auger electron spectroscopy (AES) and energy dispersive spectroscopy (EDS) were used to characterize two types of aluminum/Fe/sub 3/O/sub 4/ thermites, the first prepared by consolidating the powders into a pellet and the second prepared by spraying the powders in an Ar plasma. The aim was to examine the chemistry of these materials, with particular emphasis on the interfacial region of the fuel and oxidizer. The consolidated thermite was composed of spheroidal iron oxide particles distributed throughout a continuous aluminum metal phase whereas the plasma sprayed thermite was composed of two continuous phases, one being an iron oxide phase and the other being an aluminum metal phase. A comparison of an iron oxide-aluminum metal interface of each showed a greater degree of intermixing of the phases in the plasma sprayed thermite than in the consolidated one. 2 refs., 6 figs.


A new type admixture for PHC pile without steam-autoclaved curing is resarched and developed.Non-steam autoclaved PHC pile admixture mainly contains fly ash,granulated blast furnace and little high-activity activator.When the content of the admixture is 30%(mass fraction) in cement,the pile strength can be satisfied in the steam curing condition and steam-autoclaved process can be elided.The result shows that the PHC concrete has better workability when use our additive.In the case of the admixture dosage from 30% to 35%,the PHC concrete is kept for 14h in the steam curing,the concrete compressive strength and splitting strength can achieve 88.5MPa and 4.4MPa respectively.The result is lower than the concrete with ground quartzite powder which must be taken in both steam curing and steam-autoclaved curing.But the penetrability is nearly equal.The two kind of pile quality is both eligible and the main flexural performance can add up to grade A.


Electromagnetic information leak as a potential data security risk is more and more serious. Discussing the relationship between compromising emanations and Hamming distance is directed to preventing or reducing the electromagnetic information leakage.

I Introduction Perhaps no industry is closer to the heart of capitalism than the venture capital industry. Without it, new enterprises cannot be formed. With it, growth rates that are indispensable to the capitalist paradigm are possible. Therefore, both the ways investment decisions are made, and social systems are connected to the venture capitalist, are important for the performance of the economy. While the traditional neoclassical view of self-interest and financial profit goals dominate this industry perhaps more than any other, there is increasing activity and experimentation with ways to bring social factors into consideration. In the investment field over the past thirty years, a phenomenon called "social" investing has taken root. It is based in a theory that a single-minded focus upon financial outcomes overlooks negative social performance that eventually will impact financial performance. Most publicly offered "social investment" funds first assess companies in terms of their financial performance (i.e. return on investment on ROI), then review them for specific social issues. Numerous studies and indices support the contention that well-run social investment funds' financial performance is competitive with traditional funds. (Bruyn, Severyn, 1987; Lowry, Ritchie, 1991; Lydenberg, Steven and Domini, Amy, 1992) These social investment funds that invest in existing companies through the stock market are being supplemented with similarly motivated venture capital investment vehicles that put money into companies which are at very early stages of development and not listed on a stock exchange. Venture capital, an essential ingredient in business formation and expansion, is difficult to obtain. Most lenders impose collateral and servicing requirements that are often impossible for new and expanding businesses. Venture capitalists supply money without such requirements, but become part owners of a new enterprise. This equity investment is usually long-term, for seven to 10 years. As owners, venture capitalists have a greater role in the actual operations than a debt-holder. Although stockholders are the least secure of any investors, they also have a chance for very high returns as the value of a new company expands. Venture capitalists in the social investment tradition are sometimes referred to as "social purpose" equity investors. However, a more correct term would be "socially-guided" equity investors since both financial and social objectives are important. These investors believe that by creating jobs in new business, returns should be thought of as including factors such as reduced welfare costs, lower crime rates and greater self-esteem. Some of these investors also see themselves as making particularly valuable contributions to society by developing particular types of enterprises such as environmentally sensitive ones or ones which are employee- or minority-owned. This paper aims to investigate how these socially guided venture capitalist organizations formed, how they operate and how they perform socially and financially. II Methodology This research was conducted for the Boston-based ICA Group, a non-profit consulting organization specializing in employee-ownership.(1) The organization includes a small loan fund which takes debt positions, and in the spring of 1993 was considering whether it should also establish a venture capital fund to take equity positions. With the financial support of The Mort Foundation, the author was engaged to investigate the current activity of socially-guided equity venture capitalists. To be considered "socially-guided" an organization's investment strategy had to include two criteria. First, the investment organization had to focus upon investments under $500,000. Equity investments of this small size are notoriously difficult to find but are arguably of growing importance for an economy where small enterprise is providing an increasing share of the nation's jobs. …


The generalized likelihood plays an important role in parametric inference for prediction and empirical Bayesian models.

Statement of problem: Several alternative methods to conventional compression-molding processing for denture base material have been developed to increase the adaptation of the denture base, such as fluid resin techniques. These offered improved adaptation, dimensional stability, reduced cost and simple procedure but had low strength, higher solubility and high residual monomer levels which is related to mucosal irritation and sensitization of tissues. Subjects and Methods: Fourteen Completely Edentulous patients were selected. Patients were divided into two groups equally.one group were treated using auto-polymerized pour-type acrylic resin denture base material and the second group were treated using the conventional heat cured acrylic resin (PMMA) complete denture base material. Microbiological and cytological samples were collected. Data were statistically analyzed.Results:When comparing the two studied groups regarding mean difference of the level of both pro inflammatory salivary cytokines (TNF-α & IL-6) after delivery of the new denture, group I levels were significantly higher than group II levels at each period separately (1⁄2 hour, 1 hour 2 hours, 1 day, 3 days,1 week and 2 weeks)and when comparing between the two studied groups regarding the mean values of the number of keratinized epithelial cells before and after two months of denture delivery, it was found that there was no significant difference between them. Conclusion: Immunologically, Auto-polymerized pour-type acrylic resin denture base material elicited higher immunological response at the beginning due to its chemical composition and leaching of higher amount of residual monomer. Cytologically, both denture base materials showed an increase in the number of keratinized epithelial cells with no significant difference between them.


The title of this paper needs a little explanation. When I was approached on the possibility of giving it, I was kindly given a free hand in the choice of a subject, which could be related to any research I was doing, so long as this could, in some way or other, be related to the Glorious Revolution, and the Bill of Rights of 1689. Now for some time I have been doing research into the detention of British citizens without trial under Regulation 18B of the Defence Regulations during the 1939-45 war. Indeed I used some of this research for a Child lecture I gave in Oxford in 1987.I Of course I could not simply repeat this lecture, but it seemed to me that other parts of the material I have so far unearthed might be related to the required theme of this paper. Let me try to explain how. Outside Ulster the Glorious Revolution of 1688-89, and the constitutional settlement which followed upon it, has long ceased to have any emotional hold on the British people generally, or on lawyers in particular. I should be surprised if many people in this room have, in the last ten years, if indeed ever, actually read in full the three constitutional documents which it generated: the Heads of Grievances of 2 February 1689, the Declaration of Right of 12 February2 and the Bill of Rights itself.3 Let me assume that at least some of you are a little rusty on the matter, and simply quote to you a vision of what happened from a popular though scholarly book on the subject, written by G. M. Trevelyan, and first published in 1938:


How do geography and other barriers to the free flow of information shape the rate of knowledge diffusion? To address this question, we develop an empirical model of product discrete choice with Bayesian learning on a social network. Estimating this model using monthly data on the cholesterol-drug prescription decisions of over 50,000 U.S. physicians during January 2000 through December 2010, we find that the evolution of product choice efficiency is highly responsive to network structure changes, particularly targeted friction reductions that strengthen the strongest bilateral links.


Embelia ribes Burm. f. is an important, vulnerable, dioecious, woody climber. The fruits of Embelia ribes areused in ayurvedic formulations. The plant usually blooms during January-April and the fruits mature during June-August.Seeds are found to be dormant, so seed germination in the natural condition and rooting from the stem cuttings are verypoor. Effect of pre-germination treatments on freshly harvested seeds of Embelia ribes was carried out. The highest (75%) germination percentage was observed in GA31000 ppm treated seeds.


This article tabulates doctoral research activity in social studies education as found in "Dissertation Abstracts" published between 1982 and 1991. In this computerbased search, 499 dissertations were identified using "Dissertation Abstracts OnDisc" which is available on CDROM. A variety of descriptors were used, one of the least helpful being "social studies." From the dissertation abstracts of these 499, productivity levels were generated by yearly output, page length, gender, grade/level, terminal degree. graduate institution, research type, and topic. In addition, using data reported on five earlier dissertation overviews, research summaries were compiled for the purpose of comparison with contemporary data. Due to a transition in 1991 through 1993 in how research information was identified and categorized, the study was limited to the years 1982-1991. The primary problems of incomplete data due to the information escaping notice or the focus of the research not being clearly related to social studies based on the title alone is recognized. This study does not set out to cut any new intellectual ground, nor interpret, classify or evaluate dissertation work in social studies. The report offers general descriptive information on dissertation research. These data may be useful to graduate students in social studies, theses supervisors, and those interested in general trends in social studies dissertation research.

Clausena excavata, a native of Southeast Asia, displays characteristics of disease tolerance and adaptability to different kinds of soils. This species contains potential parents for the improvement of Citrus fruit rootstocks. However, it is tetraploid, unlike most Citrus and related species, which are diploid. Bringing the ploidy level back to 2n=2x would allow us to consider integrating this species into the varietal creation programme by somatic hybridisation. A diplohaploidisation programme by anther culture is currently being conducted. The effects of the hormonal balance on androgenesis and on the maturation of androgenetic embryos are described. Thirty-six hormonal combinations using benzylamino purine (BAP) and dichlorophenoxyacetic acid (2,4-D) were examined. The tendency to embryogenesis varies from 0 to 9% depending on the hormonal concentration and combination. A total of 106 plants were regenerated, of which 91 were hexaploid, 11 were tetraploid, and only two were diploid after the flow cytometry evaluation. Histological study showed that the embryos were derived not from somatic embryogenesis of the mother tissues but from microspores. (Resume d'auteur)


Since lupin has been introduced as a food ingredient on the market there are more and more reports concerning the potential of its proteins to bind human IgEs. However, it is yet to be proved if lupin proteins can bind only specific IgEs from the sera of people who suffer from lupin allergy. The aim of the research has been to analyse the potential of lupin globulins for binding IgEs from the sera of people who are not allergic to any legume species. Isolated lupin globulins have been subjected to immunoblotting with the sera from non-legume allergic individuals and the control sera from lupin allergic people, respectively. The immunoblotting experiment has been doubled, with a use of methyl α- D-galactopyranoside, to eliminate possible unspecific binding of IgEs to blotted proteins. Western blot analysis performed with the sera of non-legume allergic patients has revealed protein signals only in the blots that had not been incubated with galactopyranoside. When dealing with the sera of lupin allergic patients, the protein bands have been detected irrespective of the use of galactopyranoside. The results have proved that lupin globulins not only have the potential for binding specific IgEs from the sera of lupin allergic people, but also they can bind unspecific IgEs from the sera of non-allergic people.


In this paper we present a two-layered evolutionary system based on Voronoi regions to predict the initial return of a sample of initial pubic offerings. The proposed solution partitions the input space by evolving a set of prototypes using evolution strategies and subsequently fits specialized models to each of them. The exercise is repeated to produce a set of predictive models. The forecast for the return of new patterns is obtained averaging the solutions provided by different models into a single figure. The system is benchmarked against alternatives with the result of a strong relative performance.


Object re-identification (Re ID) is a key application of city-scale cameras on the edge. It is challenged by the limited accuracy of vision algorithms and the large video volume. We present Rev, a practical ReID engine that builds upon three new techniques. (1) Rev formulates ReID as a spatiotemporal query. Instead of retrieving all the images of a target object, it looks for locations and times in which the target object appeared. (2) Rev makes robust assessment of the target object occurrences by clustering unreliable object features. Each resultant cluster represents the general impression of a distinct object. (3) Rev samples cameras strategically in order to maximize its spatiotemporal coverage at low compute cost. Through an evaluation on 25 hours of videos from 25 cameras, Rev reached a high accuracy of 0.87 (recall at 5) across 70 queries. It runs at 830 × of video realtime in achieving high accuracy.


In this article, exponentiated U-quadratic distribution (EUq) is proposed by exponentiation procedure. The quantile function and r moment of the new model are computed. Estimation of parameter by the alternative maximum likelihood and estimation based on percentiles are established and compare their performances through numerical simulations. The results show that both methods are suitable for the parameter estimation of EUq distribution. A real data set is used to compare the fit of the two proposed estimation method using Kolmogorov Smirnov test (KS).


The Mobile Parallel Robot (MPR) is a new type of robot which integrates the mechanical characteristics of Mobile Robot and Parallel Robot. It can adjust position and orientation to suit to many special situations. This paper firstly analyzes the kinematics characteristics of MPR, including the inverse kinematics and the forward kinematics using analytic method. A motion simulation based on COSMOSMotion is given to illustrate the kinematic solutions are right. After analyzing the main error sources, we set up a completed error model. Then, we give the error detecting and error compensating method to increase the precision of MPR. To certificate the result, an experiment with vision system is done to illustrate that the mechanical characteristics meet the precision and MPR is a good supporting body to integrate more useful functions.


Negotiation has turned into an international critical skill. The possibility of conflicts is increased in global environments where cultural differences, values, trust and exchange of information represent a key role. Such relationships are fundamentally dependent on people who sometimes do not have the flexibility to maximize the value of cultural capital available in the organization. With an exploratory-descriptive and qualitative approach, the strategy used in this research was an embedded case study in which the analysis unit consists of three export furniture industries located in Serra Gaucha. The aim of the study was to analyze general issues that guide the ethical relationship in international negotiations in order to identify ethical behavior and attitudes in the inter-organizational relationship. Despite identifying a mismatch between respondents' speech and practice, the results show that ethics is indeed a major factor in international negotiations, as it works to enable transactions to occur properly seeking to overcome conflicts in global environments.


The first integrative taxonomic analysis of the Cyrtodactylus brevipalmatus group of Southeast Asia recovered two newly discovered populations from the Tenasserim Mountains in Suan Phueng District, Ratchaburi Province, Thailand as a new species described here as C. rukhadeva sp. nov. Based on 1397 base pairs of the mitochondrial gene NADH dehydrogenase subunit 2 (ND2), C. rukhadeva sp. nov. is the well-supported sister species to a clade containing three undescribed species, C. ngati, and C. cf. interdigitalis with a large uncorrected pairwise sequence divergence from other species in the brevipalmatus group ranging from 15.4–22.1%. Cyrtodactylus elok and C. brevipalmatus are recovered as poorly supported sister species and the well-supported sister lineage to the remainder of the brevipalmatus group. Cyrtodactylus rukhadeva sp. nov. is putatively diagnosable on the basis of a number of meristic characters and easily separated from the remaining species of the brevipalmatus group by a number of discrete morphological characters as well as its statistically significant wide separation in multivariate morphospace. The discovery of C. rukhadeva sp. nov. continues to underscore the unrealized herpetological diversity in the upland forests of the Tenasserim Mountains and that additional field work will undoubtedly result in the discovery of additional new species.


To control whiteflies attacking greenhouse tomatoes, we developed an efficient nonchemical method to control insecticide-resistant whiteflies using the attractive force of a newly devised racket-shaped electrostatic flying insect catcher (REIC). The REIC has two layers of insulated iron conductor wires (ICWs) in parallel arrays and two electrostatic direct current (DC) voltage generators that supply negative or positive voltages to the ICWs. Within each layer, the ICWs are arranged in parallel at 5-mm intervals, and connected to each other and to a negative or positive voltage generator. The negatively and positively charged ICWs are designated as ICW(–) and ICW(+), respectively. The two ICW layers are arranged in parallel with a 2-mm separation between the layers, and the ICWs of each layer are offset from the ICWs of the other layer. Adult whiteflies were blown into the space between the ICWs to determine the voltage range that captured all of the test insects. The result showed that at ≥4.0 kV, the force was strong enough that the ICWs captured all of the whiteflies, despite a wind speed of 3 m/s. The REIC is portable and easy to operate on site in a greenhouse. Whiteflies colonising tomato plants were forced to fly up in the air by gently tapping the plants, and the flying whiteflies were caught by the REIC waved once or twice in the air above the plants. The insect trapping operation was executed on greenhouse tomatoes at the time of daily plant care during the experimental period of 2 months. The results show that the tomato plants remained healthy until their fruit production, indicating that the REIC is a promising tool applicable to the practical control of insecticide-resistant whiteflies of greenhouse tomatoes.


This paper proposes a new idea for converter-based speed control optimisation for switched reluctance motor. The main objective of the speed control technique is reduced torque ripples and improved control performance achieved using matrix converter-based PID controller. Speed control performance optimisation is attained using particle swarm optimisation algorithm. The potential benefits of matrix converter are flexible current profile and lowest switching frequency, hence, minimal loss. Simulation and analysis has been evaluated using MATLAB/Simulink with the reference speed 1,500 rpm within the time frame of 0.045 seconds.


This paper examines the extraction of sediment disaster hazard area and the precipitation criteria for which evacuation is required. The past sediment disaster cases in Nagano prefecture are analyzed by using precipitation information and regional characteristics data such as topographic features, geology and land use data, and the debris flow hazard areas are extracted. The relationship between the precipitation and the disaster oc-currence in the past debris flow disasters is investigated, and then the rainfall criterion for judging the risk of sediment disaster is derived.


Background Isoliensinine(IL) is a kind monomer alkaloid of double benzyl group quinoline separated from Plumula nelumbinis,which has been speculated to have antiarrhythmic effect,Ca~(2+) andα1-receptor blockade, and reversal the left ventricular hypertrophy(LVH).It has been reported the activity of Sarco/Endoplasmic reticulum Ca~(2+)-ATP_(ase)(SERCA) in essential hypertention(EH)/LVH patients was lower than that of healthy people. Objective To investigate the effects of Isoliensinine on left ventricular hypertrophy and activity of SERCA in 2 kidney 1 clamp(2K1C) hypertensive rats.Methods 2K1C hypertensive rats were randomly received Isoliensinine (RHR-IL,5 mg/kg per day p.o,n=16) or placebo.Blood pressure,left ventricle mass index(LVMI) and the activity of myocardial SERCA were measured after 10 weeks treatment.Six untreated SD rats were served as control. Results Isoliensinine decreased BP and LV/BM ratio(IL:136.4±14.6 vs control:189.8±4.4 mm Hg,P0.01; IL:2.23±0.43 vs control:2.93±0.52,P0.05),associated with increases in activity of myocardial SERCA[IL: 0.91±0.18μmol/(g protein·min) vs control;0.61±0.23μmol/(g protein·min),P0.05],which was still lower than that of SD control rats[1.32±0.18μmol/(g protein·min),P0.01].Conclusion Isoliensinine reduced blood pressure and LV/BM ratio and concurrently enhanced myocardial SERCA activity in renovascular hypertensive rats.

The present study consisted role of silts on the Atterberg limits by correlating the percentage of particles in different size, with the Atterberg limits for seabed sediments of the Persian Gulf. Soil particles with size less than 6.5 μm had positive correlation with plastic and liquid limits. Soil particles with size bigger than 6.5 μm had negative or no correlation. Notwithstanding that, the particles with size between 2 to 6.5 μm are classified as silt by the most of soil classification systems; observation of this study showed positive correlation with the Atterberg limit. Mineralogical evidences emphasized that these particles were composed of clay minerals.


Objective: To investigate the effect of eleclroacupunclure (EA) combined with repetitive transcranial magnetic stimulation (rTMS) on the expression of synaptophysin (SYN) in hippocampus after cerebral ischemia. Method: One hundred and twenty healthy male Wistar rats were divided into normal, model, EA, rTMS and EA + rTMS group randomly. Furthermore, rats in each group were divided into 7d, 14d and 28d, 3 subgroups. Model of middle cerebral artery occlusion(MCAO) was established, followed by 7d, 14d or 28d of EA, rTMS and EA + rTMS treatment. The expression of SYN in area CA3 of the hippocampus of the ischemic cerebral hemisphere were investigated in different time points and different groups by immunofluorescence technique and semi -quantitative analysis of the expression of SYN in hippocampus of the ischemic cerebral hemisphere in different time points and different groups was processed by Western blot. Result: The expression of SYN in all 3 rehabilitation intervention groups increased significantly on days of 7, 14 and 28.The longer treatment time, the more significant expression of SYN and the expression in the EA+rTMS group was the most significant on day of 28.Conclusion: All three interventions can improve the expression of SYN in hippocampus of the ischemic cerebral hemisphere and EA + rTMS is more efficient on day of 28.


Introduction: As survival of burn patients improved after World War II, the need for a method to expand autologous skin grafts became necessary. In 1958 Meek published about a newly developed device that in combination with a pre-folded gauze could expand a 4x4 cm piece of skin nine times to postage stamps size 4x4 mm. Because of technical imperfections the technique was rather troublesome. In 1964 Tanner and Vandeput invented a far more simple technique of skin expansion, the split skin mesh graft. Disadvantages of this technique were the limited skin enlargement. Moreover the real skin enlargement in practice was only half the indicated value, and for high skin magnification large strips of split skin were required and these are scarce in a large burn.


Incorporation of green chemistry techniques in undergraduate (UG) laboratories has a great demand. The challenge is to select and modify the known fundamental reactions in a greener way to implement into UG laboratories. A practical, two-step synthesis of 4-bromoacetanilide from aniline through a greener approach is described. Design of the synthetic route is based on the fundamental concepts of green chemistry. It can be adapted in most of the UG laboratories, including those with limited facilities. In the first step, aniline is converted to acetanilide using Zn dust/Fe powder–acetic acid instead of conventional acetic anhydride. In the second step, acetanilide is brominated using ceric ammonium nitrate–KBr combination in ethanolic–aqueous medium instead of bromine. The overall concept of modification could be useful to teach students about the concept of green chemistry, functional group protection, aromatic electrophilic substitution, and laboratory techniques such as reaction setup, isolation, purifi...


Whilst there have been a number of papers that test the Watts and Zimmerman positive accounting hypotheses in a UK setting, no similar test has been made of the size effect using corporate tax burdens as a proxy for political costs. Using data for 5,998 year-ends from 1968 to 1993 this paper finds that: during 1968-79 there is evidence of a size effect; in a number of years a negative association between firm size and tax burden exists; and of the five industry categories examined, the 'mineral extractive' industry had the highest tax burden throughout the period 1968-1979.

Abstract The study examined the marketing and uses of two species of Giant African Land Snails (Archachatina marginata and Achatina achatina) in four (4) different market locations in Ibadan Oyo state, Nigeria. The data were collected using a structured and validated questionnaire administered interpersonally to 160 snail marketers in four randomly selected markets in selected Local Government Area (LGA) situated in Ibadan. Data collected were analysed using descriptive and inferential statistical tools; these include frequencies, mean, median, mode and multiple regression. Findings from the socioeconomic characteristics revealed that majority (98.1 %) of the respondents were female and only 1.9 % were male. Majority (91.9 %) of marketers were married with 27.5 % in the 31–40 years age group. Majority (89.4 %) raised their capital through personal savings and had over 16 years of marketing experience. All respondents (100 %) were involved in wholesale marketing of different species of snail whereas 65 % of them were into both wholesale and retail marketing. Also, 88.8 % were engaged in marketing of both species only. Most (70 %) of the respondents' generated income per year was between ₦10,000–₦49,999 ($26–$130). All marketers ascertained that the major purpose of snail is for consumption. Also, the budgetary analysis (costs and returns) revealed that marketing of Archachatina marginata and Achatina achatina is a profitable business among the marketers with a high rate of return on investment. The most efficient market for both snail species was Sango market with efficiency values 1.77 and 1.82 for A. achatina and A. marginata, respectively. The coefficient of multiple determination, R2 value of 0.689 indicated that 68.9 % of the variation in the marketing price of snail is explained by transportation cost, cost price of snail and market tariff. The marketing efficiency was greater than one in all markets which showed that the markets were efficient in the marketing of Archachatina marginata and Achatina achatina. The study concluded that snail marketing is profitable given the market efficiencies and rate of returns on investment. Policy recommendation towards reduction in cost of transportation and market tariff is suggested as this would bring about improved market efficiencies and more returns.

Objective(s) This study planned to assess antidepressant like activity of aqueous extract from leaves of Citrus maxima Merr. (Rutaceae). Materials and Methods Boiling was used for aqueous extraction. Acute toxicity study was performed in mice. Antidepressant activity was studied using locomotor activity test, modified forced swimming test (FST) and tail suspension test (TST). Three doses 100, 200 and 300 mg/kg of aqueous extract of leaves were selected for testing. Fluoxetine (20 mg/kg, i.p.) and imipramine (30 mg/kg, i.p.) were used as the standard drugs. Results Aqueous extract of Citrus maxima leaves significantly reduced immobility time in both TST and FST. In locomotor activity testing it showed psychostimulant effect. Extract increased the climbing behavior in FST, which is similar to effect observed with imipramine. Conclusion The results of this study suggest that antidepressant like effect of Citrus maxima seems to be mediated by an increase in norepinephrine level in synapses.


Therapeutic antibodies, due to their high affinity and specificity toward their biological targets, may demonstrate reduced harmful side effects compared with traditional drug moieties. While most of the as‐yet clinically approved antibody therapeutics have targeted extracellular or membrane‐bound domains, the ability to target intracellular antigens with antibodies opens up tremendous opportunities for imaging, diagnosis, and therapeutic applications. Generally, delivery concerns have limited the ability to target intracellular antigens, as many antibodies cannot easily cross the cell membrane due to their size and surface chemistry. Delivery platforms have been explored to address this issue, including physical methods, fusion protein/peptide techniques, and synthetic carrier‐based systems. This review summarizes the progress of carrier‐based intracellular antibody delivery systems employing synthetic lipids, polymers, and inorganic nanomaterials. Antibodies targeting various epitopes have been loaded through adsorption, conjugation, or physical encapsulation strategies. Successful intracellular deliveries have been demonstrated largely through fluorescence imaging using dye‐labeled antibody cargos. Specific synthetic delivery platforms have great potential for ex vivo and in vivo therapeutic applications. Challenges and opportunities are further discussed for material scientists to explore in this research area.


What Is Specific about Turbulence with Combustion? In recent years, nothing seems to have inspired researchers in the combustion community so much as the unresolved problems in turbulent combustion. Turbulence in itself is far from being fully understood; it is probably the most significant unresolved problem in classical physics. Since the flow is turbulent in nearly all engineering applications, the urgent need to resolve engineering problems has led to preliminary solutions called turbulence models. These models use systematic mathematical derivations based on the Navier–Stokes equations up to a certain point, but then they introduce closure hypotheses that rely on dimensional arguments and require empirical input. This semiempirical nature of turbulence models puts them into the category of an art rather than a science. For high Reynolds number flows the so-called eddy cascade hypothesis forms the basis for closure of turbulence models. Large eddies break up into smaller eddies, which in turn break up into even smaller ones, until the smallest eddies disappear due to viscous forces. This leads to scale invariance of energy transfer in the inertial subrange of turbulence. We will denote this as inertial range invariance in this book. It is the most important hypothesis for large Reynolds number turbulent flows and has been built into all classical turbulence models, which thereby satisfy the requirement of Reynolds number independence in the large Reynolds number limit. Viscous effects are of importance in the vicinity of solid walls only, a region of minor importance for combustion. The apparent success of turbulence models in solving engineering problems has encouraged similar approaches for turbulent combustion, which consequently led to the formulation of turbulent combustion models. This is, however, where problems arise.


ABSTRACT The study of political activism has neglected people's personal and social relationships to time. Age, life course and generation have become increasing important experiences for understanding political participation and political outcomes (e.g. Brexit), and current policies of austerity across the world are affecting people of all ages. At a time when social science is struggling to understand the rapid and unexpected changes to the current political landscape, the essay argues that the study of political activism can be enriched by engaging with the temporal dimensions of people's everyday social experiences because it enables the discovery of political activism in mundane activities as well as in banal spaces. The authors suggest that a values-based approach that focuses on people's relationships of concern would be a suitable way to surface contemporary political sites and experiences of activism across the life course and for different generations.


In recent decades there has been a shift towards greater scrutiny of the commerciality of potential new water infrastructure projects, particularly where public investment is involved. This report contains information to assist in planning and evaluating the viability of investments in new large-scale irrigated development, quantifying the costs, benefits and risks involved. Three study areas across northern Australia were considered: the Fitzroy catchment (WA), a set of catchments around Darwin (NT) and the Mitchell catchment (QLD). The primary focus of this Assessment, as documented in the companion reports, is an analysis of water and soil resources to help identify opportunities and constraints for new irrigated agriculture in the Assessment area. This report complements the overall Assessment by identifying the social, institutional and economic conditions that would be required for those potential opportunities to be most likely to succeed. Part I of the report begins by setting the context for irrigated development in the study areas, providing background information on the communities, economies and existing infrastructure from which potential new developments would build. Part II of the report considers social and institutional aspects of new irrigated development to help identify those opportunities that are most attractive to investors and stakeholders, and that meet legal, regulatory and policy requirements. Part III then provides information on the costs and benefits of developing new irrigated agriculture, to identify what would be required for different types of development to be financially and economically viable. The broad conclusion of this report is that it would be challenging to find opportunities for new irrigated agriculture in the Assessment area that met regulatory requirements and gained stakeholder support while also providing a financial rate of return to investors commensurate with the level of risk involved. Revenue at the farm gate from broadacre cropping alone would be unlikely to fully cover the costs of new irrigated development. It is more likely that any case to justify new developments would rely on additional benefits beyond the farm gate such as value adding from local processing, generation of renewable electricity (hydro-electric power or bioenergy), co-benefits to other industries such as grazing or tourism, and/or other indirect benefits to local communities. The possible benefits of integrated schemes would need to be carefully balanced against the extra complexity and elevated risks from having additional sources of vulnerability that could lead to financial failure. Successful investments would likely have to combine meeting the above criteria with the cheapest sources of water, lowest risks (including water reliability, agronomic, climatic and regulatory risks) and most productive mixes of land and farming options. The main findings from this report are summarised below by the four main topics of analysis. Stakeholders and investors Legal and institutional context Scheme commerciality Regional economics Reference information on demographics, industries and infrastructure costs (details under above sub-headings are contained in the full Executive Summary)


The corpus-based study on Semantic Accessibility Scale(SAS) is a useful method to evaluate the acceptance of electronic texts.On the basis of large-scale natural language texts,this paper compares The Old Man and the Sea and "ゆきぐに" from English and Japanese corpora by means of the information retrieval and semantic assignment.A conclusion is drawn that SAS is related to vocabulary density(P1,P2),vocabulary length(H) and sentence length(L),namely SAS=P2/[P1×0.4×(L+H)].Correspondingly,different sampling ratios will not result in fundamental difference of SAS.This study provides the theoretical support for the literary critics to analyze the acceptance of internet-based texts.


Over the course of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the clinical, scientific, and public health communities have had to respond to new viral genetic variants. Each one has triggered a flurry of media attention, a range of reactions from the scientific community, and calls from governments to either "stay calm" or pursue immediate countermeasures. While many scientists were initially skeptical about the significance of the D614G alteration, the emergence of the new "UK variant"—lineage B.1.1.7—has raised widespread concern. Understanding which variants are concerning, and why, requires an appreciation of virus evolution and the genomic epidemiology of SARS-CoV-2.


Activation of vascular endothelial growth factor VEGFR-3 leads to proliferation, differentiation and migration of lymphatic endothelial cells. The role of this factor in periodontal tissues in normal and inflammatory conditions requires extensive study. The purpose of this study: to study the distribution and expression of VEGFR-3 in the lymphatic vessels of the gum lamina proper during inflammation and the use of a diode laser in young and mature people. Slices of human gum biopsy material were studied by immunohistochemical method. As a result of the research , it was found that in the patients with conditionally healthy periodontal tissues, the number of lymphatic vessels depends on the age and differs in young patients compared to mature patients by 1.2 times. Simultaneouslyбол, it was found that in the control groups, the majority of vessels do not contain VEGFR-3 or have weak receptor expression regardless of age. The tendency to VEGFR-3-mediated increasing of the number of lymphatic vessels during the inflammation is observed only at the age of 41 to 60, however, the intensity of the expression of the VEGF type 3 receptor in chronic gingival inflammation shifts towards the increasing of the vessels with medium and strong VEGFR-3 expression in both groups. As a result of the study, it was found that the tendency to change the number of VEGFR-3-positive vessels is observed only in inflamed gum tissue in patients after 41. Diode laser has a stimulating effect on VEGFR-3-mediated vascular circulation in young patients, while in mature patients, diode laser therapy leads to increase the part of lymphatic vessels with medium and strong expression of the studied receptor, but practically does not affect on the number of detected vessels.


Through water culture experiment,298 varieties of rice were used in this study to classify and evaluate their genotypic differences in biomass and phosphorus utilization efficiency under the same P fertilization condition,and further discussed the relationship between the biological characters of rice and phosphorus utilization efficiency.The results indicated that:(1)Difference of biomass and phosphorus utilization efficiency of the cultivars used in this study was very large,the variation coefficient of the biomass was 36.03% and 36.85%,and the variation coefficient of the phosphorus utilization efficiency was 15.80% and 17.73%.(2)The whole rice variety resources were decomposed into five types by dynamic clustering.And significant differences were observed in phosphorus use efficiency for drymatter among five types.At tillering stage and jointing-booting stage,theⅠ-type was high phosphorus utilization efficiency,those biomass was 3.22 times and 3.08 times,and phosphorus utilization efficiency was 1.73 times and 1.82 times higher than the low phosphorus utilization efficiency Ⅴ-type.(3)Meanwhile,there were significant differences in phosphorus content and accumulation between the high phosphorus utilization efficiency and low phosphorus utilization efficiency rice.The high phosphorus utilization efficiency ofⅠ-type rice had lower phosphorus content and higher phosphorus accumulation than the low phosphorus utilization efficiency of Ⅴ-type,they could absorbs less phosphorus to maintain physiological and metabolic functions,and produced bigger biomass.(4)The biological characters,like plant height and tiller number,had significant difference in the different phosphorus utilization efficiency rice types,it also had a significantly correlation to phosphorus utilization efficiency.
