To the Editor: Life is complicated and gets more so all the time, but there is simplicity to be found in basic laws that govern our lives. We live and die by these laws. Our bodies are sustained by adequate intake of food, water, and air—a basic law. We are bound to earth by gravity, a law investigated and pronounced by Galileo in 1604.1 But gravity also contributes to the aging process, and, under some circumstances, we can die violently because of its effects. Another natural law first described by James Clark Maxwell in 18652 states that all substances are surrounded by an electromagnetic field. All electrical appliances create an artificial electromagnetic field, and exposure to too much of this can have adverse effects on health. These effects are more insidious than those of the force of gravity. It is common knowledge in metaphysics that some gifted individuals can see this energy field surrounding our bodies, which is called an aura. One of the most important laws of nature, of which relatively few people are aware and which many of our own profession ignore, is the relationship between structure and function in the human body. When structure deviates from normal, no matter what the cause, it eventually causes functional changes. When function is altered, it leads to microscopic or gross structural changes. This law was pronounced by Andrew Taylor Still, MD, DO, in 1874.3 Dr Still developed natural and effective methods of correcting structure and function abnormalities, a tremendous contribution to healthcare. We not only live and die by this law, but our quality of life lies squarely in its hands. Recently, another important law has been investigated called tensegrity. It involves many of the complex mysteries of life. One of those mysteries is the multistep process of the formation of molecules into substances, and with chemical changes, transformation of substances into cellular forms, cells into tissues, tissues into organ systems, and organic systems into complex forms that can grow, reproduce, develop individual characteristics, and perform complex functions. We are learning more about the architecture of this complex phenomenon and what drives it: how the human body works through its nervous system, chemical modulators, deoxyribonucleic acid, and genes and the identification of genomes. Both organic and inorganic substances have geometric patterns of spirals, pentagons, and triangular forms and contain many of the same building blocks (eg, carbon, hydrogen, oxygen, sodium, phosphorus). The main difference between organic and inorganic substances is in how atoms are arranged in three-dimensional space, termed selfassembly. Donald E. Ingber, MD, PhD,4 concluded after research that both organic and inorganic substances self-assemble through a common form of architecture known as tensegrity. This system stabilizes itself mechanically because of the manner in which tensional and compressive forces are distributed and balanced within the structure. In living structures, cells are continually replaced, so structure is maintained by architectural forces of which there are two categories. One category contains geodesic domes and a framework of rigid struts that can bear both tension and compression. The struts are connected in triangles, pentagons, or hexagons arranged to maintain stability. In the second category, the struts are prestressed. The compression-bearing struts stretch the tension-bearing struts, and viceversa, which distributes forces and stabilizes the mechanism. Both structures have one important feature in that tension is constantly transmitted across all structural members, which also produces stability. In humans, the bones are compression struts; muscles, tendons, ligaments, and fascias are the tension struts. At the microscopic level, cells contain a cytoskeleton of three polymers: microfilaments, intermediate filaments, and microtubules. These maintain cell conformation, which can be altered by contact with adjacent structures. Thus, cells are governed primarily by tensegrity and not by the colloidal solutions they contain. Tensegrity is even involved in nerve fiber formation and repair. The cytoskeleton of cells can be altered by changing the forces operating across the cell surface. This change has been shown to affect the biochemical reactions within the cell, especially those of protein, which forms the cellular framework. This is strong evidence of the importance of adequate protein intake in the diet. A new science is emerging to study the human proteome, the collective body of protein made by cells and tissues.5 This is proving to be more complicated than the study of genes. Although genes contain the chemical organizers and blueprints of our tissues, proteins provide the building blocks. Deoxyribonucleic acid is built from adenine, cytosine, guanine, and thymine, while proteins are made from twenty different amino acids, providing an infinite variety of combinations. When the shape of cells is altered, it changes the way cells operate in reproduction, differentiation, and function. This is structure and function at the cellular level. The next step in self-assembly is the formation of tissues, which behave mechanically and respond in a manner called linear stiffening. In response to increasing tensions, tissues create increased resistance and rearrange themselves in the direction of stress. This fully explains the orientation of fibers in fascia in the lines of stress we see osteopathically. The geodesic structure referred to earlier occurs everywhere in nature, indicating a basic physical law, tensegrity. Even in irregular structures, such as protein, which are long chains of amino acids, tension is produced by the attractive force of hydrogen bonds, while the protein coil resists compression. All tensegrity structures exhibit characteristic resonant frequencies of vibration that tune all interconnected elements into one. This is consistent with the osteopathic concept of all body parts being an integral part of the whole. Tensegrity explains why trees on steep mountain slopes are able to grow straight up, unless deformed by strong prevailing winds. It is even speculated that the conformity of the universe is maintained by the compressive forces of gravity and the tensional forces of the centrifigal orbits of planetary bodies. Tensegrity explains why we, in our mobile forms, with the help of our com-


The classical theory of elasticity describing three- and lower-dimensional systems is generalized to higher-dimensional spaces. The elastic properties of quasicrystals can be derived from this theory, appropriately. The practical application is given to pentagonal, octagonal, dodecagonal, and icosahedral quasicrystals. The explicit form is obtained for all elastic equations including Hooke's law, equilibrium equation, etc., in all the cases mentioned above.


e20630 Background: Metastatic disease at the time of lung cancer diagnosis influences therapy choice and prognosis. Metastasis to the brain, bones, and liver may lead to higher morbidity. Differences in the prevalence of metastatic sites among patients (pts) of White (W) and Black (B) race and their association with overall survival need further elucidation. Methods: Utilizing the SEER database from 2010-2019, we identified W and B pts with metastatic small cell (SCLC), squamous cell (SQ-NSCLC), and adenocarcinoma (AD-NSCLC). Only pts with bone, brain, or liver metastasis (mets) at diagnosis were included. Metastatic site prevalence rates were determined. Cox proportional hazard ratios for survival were calculated while controlling for gender, ethnicity, other metastatic sites, chemotherapy, and radiation. Results: Total of 338,411 pts, 11.4% of B race. In SCLC, B pts had a higher prevalence of brain mets, while W pts demonstrated a higher prevalence of bone and liver mets. Survival between W and B pts with SCLC was comparable except for modest superior survival in B pts with liver mets. In SQ-NSCLC, metastatic disease for the 3 sites of interest was more prevalent in B pts, most notably in brain. However, survival did not differ. In AD-NSCLC, B pts were more likely to present with brain and liver mets. B pts with bone mets had inferior survival. Conclusions: Significant differences in patterns of mets at the time of lung cancer diagnosis between W and B pts exist. B pts with SCLC and liver mets had longer survival. Interestingly, B pts with bone mets and SQ-NSCLC had better survival while those with AD-NSCLC fared worse. Multiple factors, including socioeconomic, environmental/smoking patterns and access to healthcare, may have contributed. Further studies are needed. [Table: see text]


Abstract:
Background & Aims: The aim of this study was to evaluate the accuracy of Cone-beam Computerized Tomography (CBCT) linear measurements in dry mandibles by comparing them with direct measurements.
Methods: Two human dry mandibles were used in this study. Thirteen sites were selected on each mandible. Specimens were scanned by CBCT and linear measurements were made using Planmeca Romexis 2.3.0.R software. Mandibles were cut into sections at marked locations and the same distances were measured by a digital caliper. Differences between two methods were assessed using paired t- test.
Results: The mean differences for bone height, bone width and the crest-canal distance between CBCT and digital caliper measurements were -0.47±1 mm, -0.14±0.78 mm and 0.00±0.76 mm respectively. The differences were only, significant for bone height measurements (P<0.05). There was a high carreltion between the result of CBCT and gold standard.
Conclusion: The results of this in-vitro study on mandible indicate that, although there is a statistically significant difference for bone height measurements between the two methods, the difference is not significant in clinical applications. Thus, CBCT was shown to be a useful technique for preoperative dental implant planning.

In order to further reduce the vibration transmitted from vehicle to driver, a new model of driver scissors linkage seat suspension was put forward, in which an air spring with auxiliary chamber and a MR damper are between the face and floor of the seat. The motion differential equation of this seat suspension system was established and the theoretical computing formulation of it's equivalent vertical stiffness, equivalent damping coefficient, natural frequency and damping rate were deduced. Besides, taking HY-Z04 scissors linkage seat, SK37-6 air spring of ContiTech and RD-1005-3 MR damper of LORD as an example, the equivalent stiffness and damping coefficient in different conditions of the air spring pressure, the sprung mass, the orifice diameter and MR damping were computed and analyzed. The study results show that the air spring pressure, the sprung mass, the orifice diameter and MR damping all have obvious influence on the equivalent stiffness and damping coefficient, so the seat comfort can be improved by changing the air spring pressure, the orifice diameter and MR damping according to driver's weight and road condition.


The paper presents the results of a research obtained by examining the level of development of phonological skill and its influence on reading ability. The sample included 36 children of the second grade of regular elementary school (15 boys and 21 girls, average age: 8years and 8 months). The measuring instruments were: the Articulation Test, Repetition of Words and Logotomes Test, Phonemes Deletion Tasks, Voice Analysis Test, Voice Synthesis Test and Three-dimensional Reading Test. It was established that reading ability was not statistically significantly linked with voice articulation and voice analysis, but there was a statistically significant connection between reading ability and repetition of words and logotomes, phoneme deletion and voice synthesis. The reading ability is primarily determined by phonological skills of voice synthesis, phoneme deletion and repetition of words and logotomes. Extremely important is to develop cognitive functions and processes such as working (phonological) memory, phonological elaboration, lexical representation, auditive perception and discrimination.


Biological organisms living in any environment can expel DNA into their surroundings through fecal matter, mucus, shed skin, gametes, etc. Here we examine the utility of metabarcoding from a variety of environmental DNA (eDNA) substrates collected from the Pilbara region, Western Australia, to assess the feasibility for both stygo- and troglofauna detection. With metabarcoding, we confirm eDNA from both stygo- and troglofauna is detectable via molecules. In addition, our proof-of-concept and validation of using an eDNA approach was confirmed when both traditional morphological and metabarcoding assessments were compared. The metabarcoding results from the eDNA substrates are very encouraging when compared to the results of traditional morphological assessments, although highlighted the need for comprehensive DNA reference databases to be accessible for metabarcoding comparisons in order to obtain species identifications and community assemblage profiles. Furthermore, our results indicate a standardised field sampling collection method is warranted in order to maximise the success of subterranean eDNA detection from environmental substrates. eDNA data collected suggest metabarcoding approaches will become a powerful part of the toolkit to study subterranean fauna.


A postulate of systems biology is that, within the sum total of its genomic data, a network map of all functional interactions exists for each organism ([5][1]), and this "interaction map" can be assembled from that data agglomeration through the application of integration algorithms ([9][2], [


A wideband dual-circularly polarized (CP) linear antenna array is presented in this paper. Firstly, a dual-CP endfire antenna based on septum polarizer is designed as the element for the array. Secondly, the feeding network is realized by ridge gap waveguide. Then a 1×8 linear antenna array is built up by the elements. The proposed array antenna achieves wide impedance bandwidth of 44.6% with the reflection coefficient below -10 dB, the isolation between ports greater than 15 dB, and a wide 3-dB axial ratio (AR) bandwidth of 46.2%.

Homotopy analysis method gives a strong approximate analytic solution to almost all nonlinear problems. In this paper, we have considered magnetohydrodynamics (MHD) sink flow with a velocity power index of , 1 - for which exact analytic solution is given by Zhang et al. [14]. This problem is studied by using homotopy analysis method (HAM). The analytical solution obtained by Zhang et al. [14] exactly matches with HAM for 1 = h for a particular choice of linear operator which is an interesting coincidence. This provides greater insight into HAM.


The aim - to study and to analyze the indicators of the humoral link of the immune system in patients with systemic connective tissue diseases with chronic activated HSV 1/2 infection and to assess the effect of the revealed disorders on the development of autoimmune pathology.
Materials and methods. We examined 380 patients with systemic diseases of the connective tissue (systemic lupus erythematosus, systemic vasculitis, rheumatoid arthritis, psoriasis) with chronic HSV 1/2 infection at the age of 21-67 years. In 45 of them, using the modern molecular genetic diagnosis of herpes simplex, the active phase of chronic HSV 1/2 infection was verified based on the results of the polymerase chain reaction, and in the other 335, the latent phase was verified. The control group consisted of 20 healthy individuals of the appropriate age and gender. In patients with systemic connective tissue diseases with chronic HSV 1/2 infection, the humoral immunity indices were studied: levels of complement component C3 and IFN-a in saliva and blood and acquired: concentration of common major immunoglobulinins: IgG, IgM IgA, IgE; specific IgM and IgG to HSV 1/2; levels of cryoglobulins, cryofibrinogen, CІC in serum. Statistical processing of the results of the study was carried out using generally accepted methods of variation statistics.
Results. In patients with systemic diseases of connective tissue with chronic HSV 1/2 infection, activation of the humoral immunity was detected, it was especially evident in the active phase of the infection and was characterized by an increase in the antibody production of specific IgM HSV 1/2 and IgG HSV 1/2, аn increase in the levels of CIC, IgM, IgA and IgE, cryoprecipitation proteins, IFN-a in the blood. In the latent phase of HSV 1/2 infection the levels of IgG production of HSV 1/2, IgE, CEC, cryofibrinogen and cryoglobulins in the blood serum of these patients increased.
Conclusions. The presence of chronic activated HSV 1/2 infection in patients with systemic diseases of the connective tissue causes activation of the humoral immunity, creates the conditions for the development of autoimmune processes.


The uneven development of rehabilitation services in the UK is a cause of continuing concernfl]. Major difficulties arise from the disjointed provision of services[2], the tunnel vision of members of the professions concerned [3], inadequate explanation and discussion with the disabled person and failure to involve him or her in the decisions taken about treatment, and the management of disability [4,5]. The Open University's course 'The Handicapped Person in the Community' is a major attempt to broaden knowledge and understanding be- tween different professional groups and disabled people and their families, to suggest a more questioning attitude towards the roles of 'adviser' and 'helper', and to intro-duce alternative approaches to the solution of problems faced by disabled people. We report a current local effort, jointly organised by the School of Continuing Education of the University of Kent at Canterbury and the Kent Postgraduate Medical Centre, which was intended to bring together doctors, remedial therapists, nurses, social workers, managers, voluntary workers, disabled people and their carers so that they could share both their knowledge and experience.


The four statistics examined are available for use in comparing two dependent correlation coefficients (correlations between two predictors and a common criterion from a single sample wherein the predictors themselves may be correlated). There has been much past discussion in the literature of the properties and appropriate situations for these statistics. Two somewhat counterintuitive results are given here; both are examined using variables of interest to applied clinical researchers. It is shown by example that there are situations for which the observed value of these statistics increases (and thus power increases) as the predictor intercorrelation increases. Further, it is shown that there are situations for which the observed statistics increase as the magnitude (but not the difference) of the two correlations being compared increases, holding the predictor intercorrelation constant.


Passive design strategies can reduce heating and cooling demands with integration of more efficient building systems as well as the potential to integrate modular off-site construction technology and its technical systems to offset overall energy consumption. This paper presents an analysis of the development of modular building design elements to improve thermal performance of a base-case high rise residential development before different retrofitting scenarios are undertaken to optimise the building's energy performance and the occupants' thermal comfort in the coastline city of Famagusta, Cyprus. This study adopts a quantitative research design primarily using multi-objective optimisation and the energy simulation of a base-case prototype building in both extreme seasons (summer and winter). The selected representative high-rise residential development is modelled using Integrated Environmental Solutions' Virtual Environment (IES-VE) software where extensive dynamic thermal simulations have been produced to assess existing energy performance and energy effectiveness of retrofitting strategies. The representative apartment units were modelled using dominant representative energy profiles, and in all cases the preliminary results demonstrated that the physical properties of the building led to high levels of discomfort as well as higher than average heating and cooling loads. The results demonstrated that in the non-retrofitted case, the cooling and heating comprised the biggest part (67%) of the total energy consumption, helping with the second phase of the study, which is investigation of effective district scale retrofitting scenarios in the decision-making process to uptake delivery of policy implications with taking into account households' real occupancy profiles in the South-eastern Mediterranean climate.


The thermal inertia of buildings, along with the flexibility associated with thermostatically controlled loads (TCL) allows heating, ventilation and cooling (HVAC) systems to be used for grid demand response (DR). In this work, we consider a hydronic HVAC system that serves multiple units in a residential building to meet their space heating requirements. We aim to determine the optimal power flow to each unit that minimizes the power costs incurred by the building's occupants while keeping in consideration their thermal comfort. The DR program is assumed to allow the building temperatures to deviate from the set-points up to a maximum limit. Despite the complex, non-linear structure of the problem, we show how the optimal solutions can be obtained efficiently using quadratic programming. Since HVAC systems can run on either electricity or natural gas, we study the efficacy of the DR regime for both hourly electricity prices and flat gas prices over the course of 24 hours. We also study the optimal thermal power and the evolution of unit temperatures for various energy pricing schemes.


We study a class of iterative combinatorial auctions which can be viewed as subgradient descent methods for the problem of pricing bundles to balance supply and demand. We provide concrete convergence rates for auctions in this class, bounding the number of auction rounds needed to reach clearing prices. Our analysis allows for a variety of pricing schemes, including item, bundle, and polynomial pricing, and the respective convergence rates confirm that more expressive pricing schemes come at the cost of slower convergence. We consider two models of bidder behavior. In the first model, bidders behave stochastically according to a random utility model, which includes standard best-response bidding as a special case. In the second model, bidders can behave arbitrarily (even adversarially), and meaningful convergence relies on properly designed activity rules.


International standardization has become more important because of the trend of economic globalization. Whoever has mastered the standards will have the right to speak. In developed countries, standard competition is the apex of all fields, and promoting the internationalization of domestic technology and standards is an effective way to promote the country's market leader and international status. With the continuous improvement of China's market competitiveness, the internationalization of standards related to the power industry has become more essential, therefore, it is urgent to further strengthen the development process of internationalization of standards in China's power industry. Starting from the international standard project in the field of smart grid, this paper studies the difficulties of current international standard project in the field of smart grid, in addition, systematically analyzes the key problems of the standard project in the field of power grid under the internationalization of China's standards. At last, the practical measures are given.


The article presents the results of experiments intended to leach copper from ore heaps of complex mineral composition biochemically. The processing of such heaps is complicated due to the presence of oxidized copper minerals among significant fragments of sulfide minerals and iron-calcium silicates. This factor does not allow to perform standard sulfuric acid leaching effectively without the use of additional oxidation catalysts, or to apply beneficiation methods for that kind of raw materials. Use of A. Ferrooxidans bacteria adapted to the composition of the copper dump, as a bio-catalytic agent, significantly accelerates the leaching process and increases the copper recovery degree into the productive solution.


Most recently, the old discussion on identifying gaps in existing nuclear liability regimes as well as finding ways how to reach a uniform standard of claims arising from a nuclear incident can be considered as more actual than in the years before. The so called "Nuclear Renaissance" or "Nuclear New Build" can't be limited to nuclear sites multiplications, but must occur parallel with creating and strengthening legal framework for nuclear and radiation safety, security and safe – guarding. As OECD⁄NEA stressed in its Nuclear Energy Outlook 2008, "the international community must be prepared to adapt the existing international legal framework to those new realities." Due to the fact, nuclear liability law is considered to be one of the core legal issues affiliated to the peaceful use of the nuclear energy, legal discussions on uniform standard of nuclear liability rules will be for sure essential part of the further development. Most currently, the discussion on nuclear liability harmonisation has been opened also on the EU level. While silent on this issue during the decades after signing the Euratom Treaty in 1957, the attitude of the EU institutions (the European Economic and Social Committee and the European Commission in particular) towards regulating the nuclear liability in the EU Law changed dramatically after the 2004 and 2008 enlargements. Discussion on nuclear liability "patchwork situation" was opened under the aegis of the European Commission already in 2005, but it then it was paralysed because of the strict resistance of the new Central- and Eastern European member states. On the occasion of the AIDN/INLA biannual meeting hold in Brussels in September 2007, EC Commissioner for Energy Andris Piebalgs pointed out current situation in the area of nuclear liability framework in the EC/Euratom, which was described as very unsatisfactory from the EC Commissions' point of view. Commissioner Piebalgs announced a further activity of the European Communities towards harmonising nuclear liability regime. Some months later, in December 2007, the European Commission commissioned a Spanish Law Firm to develop and distribute a questionnaire to explore the views of EU states and of EU industry on the current nuclear liability situation with the view to harmonizing that field of law within the EU and to evaluate their results gained by the questionnaire. Due to the nature of options presented in the questionnaire, one can anticipate, from the point of view of the European Commission, a future harmonisation of the nuclear liability based on the provisions of the revised Paris Convention will be desirable. Such a fact is of major importance for the "new" EU Member States in the Central and Eastern Europe (Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland and Slovakia), which joined the Vienna Convention during the 1990s. This contribution is aiming to point out the perspectives of an EU – wide harmonisation of the nuclear liability from the point of view of the current Contracting Parties of the Vienna Convention, which became EU member countries during the two enlargements in 2004 and 2008.


C entral venous catheters are useful diagnostic and therapeutic devices for administration of fluids, drugs, and parenteral nutrition; for central venous pressure monitoring; and for vascular access for extracorporal treatment regimens. As with most invasive procedures, central venous catheterization is associated with numerous potential complications, both during the placement and later in the long-term maintenance. Pneumothorax, bleeding, arrhythmias, malposition, thrombosis, and infections are well-known complications (1,2). Aberrant locations usually involve malposition of catheters within major tributaries of the superior vena cava (3-5). We recently observed a misdirection of a dialysis catheter into the accessory hemiazygos vein in a patient presenting with back pain.


The purpose of this paper is to develop a management perspective on the influence of crosscultural management (CCM) and organizational change (OC) as an inorganic growth strategy in the processes of mergers and acquisitions (M&A). It is common practice for companies to expand internationally based on inorganic growth strategies, for which mergers and acquisitions are of great significance. However, the results of these processes have not been successful. This review indicates that M&A processes are influenced by elements linked to cross-cultural management, organizational change and cultural factors. It delves into the issue of organizational change variables, describing possible scenarios in which M&A processes may have a better performance and how cross-cultural management will influence the whole process. We propose a model that connects cross-cultural management, organizational change and corporate culture to create a situation of positive synergy that ensures the generation of value to shareholders in inorganic growth projects.


In order to improve the capabilities of managing the roof and enduring the load of the standing shield's hydraulic support,the motion trace of the roof beam endpoint should be approximate twisted pair line,and its maximal horizontal swing value should be minimal.In this paper,the motion characteristics for the four-bar linkage of the hydraulic support were analyzed,and its mathematic model for optimization design was established.The length of each bar and the correspondent parameters were determined by genetic algorithm,when the motion trace of the roof beam endpoint was twisted pair line,and the maximal horizontal swing value e of the roof beam endpoint was minimal.The ZY35 hydraulic support was taken as an example to validate the optimization result.The ideal design parameters of the ZY35 hydraulic support can be obtained based on genetic algorithm,and its working status and support effect is stable and favorable.

We propose a new definition of quantum metric spaces, or W*-metric spaces, in the setting of von Neumann algebras. Our definition effectively reduces to the classical notion in the atomic abelian case, has both concrete and intrinsic characterizations, and admits a wide variety of tractable examples. A natural application and motivation of our theory is a mutual generalization of the standard models of classical and quantum error correction.

The present study was designed to evaluate the biochemical profiles of C. tenuicollis in sheep. 36 cysts were collected from Iranian fat-tailed sheep slaughtered at the main abattoir of Shiraz (Southwest Province, Iran). Cysticerci were attached to the omentum, mesenteries and liver and transferred to the laboratory. All cyst fluids were centrifuged separately and the supernatants were analyzed for various biochemical parameters. Various biochemical parameters (glucose, total protein, urea nitrogen, uric acid, triglycerides, cholesterol, creatinine, calcium, sodium and potassium) were measured using conventional laboratory methods. The concentrations of glucose, triglyceride, cholesterol, total protein, urea nitrogen, creatinine , uric acid, Na , K, Ca and phosphorous in cyst fluid were 6.265± 0.792 mmol/L, 0.777± 0.120 mmol/L , 0.167 ± 0.031 mmol/L, 3.18± 0.03 g/L, 15.407 ± 1.160 mmol/L, 71.957 ± 14.055 μmol/L and 33.147 ± 8.926 μmol/L, 115.71 ± 6.40 mmol/L, 9.357 ± 0.984 mmol/L, 2.307 ± 0.495 mmol/L and 0.867 ± 0.194 mmol/L respectively. The activities of AST and ALT in cyst fluid were 152.39 ± 48.94 and 14.29 ± 3.63 U/L respectively.


Abstract The Australian leaf-mining fly,Hydrellia balciunasi,was first released as a biological control agent for the management of the submersed aquatic plant,Hydrilla verticillatain August 1989 in southern Florida. Since then, 284,684 individuals have been released at seven Florida and four Texas sites. Despite this effort, populations have persisted at just two Texas sites: Sheldon Reservoir near Houston and Lake Raven in Huntsville State Park.H. balciunasilevels have remained relatively low at these sites, averaging, at best, less than 1000 immatures/kg wet plant weight. All other collections were substantially lower. Reasons for poor establishment are unknown but probably relate to a complex of factors, including competition with another introduced leaf-mining species, parasitism by native wasps, poor host quality, genetic differences between Australian and United States hydrilla resulting in mismatched physiological strains of agent and host plant, and possibly inbreeding depression in laboratory colonies used for releases.


Recombinant proteins expressed in cell culture have been shown to be relevant in the biopharmaceutical production focusing human health. The current work investigated the precipitation process of recAVLOEc protein, synthesized by E. coli BL21 (DE3) pLysS cells. The system is used for the AVLO expression that shown antiviral activity and it was found in the hemolymph of Lonomia obliqua caterpillar. The precipitation was conducted by the use of conventional salts (ammonium sulfate and sodium sulfate) and the volatile ammonium carbamate salt. Initially, the precipitated protein obtained from bacterial lysate was added to L929 cells to evaluate the cytotoxic effect; and besides Vero cells were infected with measles virus to verify the antiviral action of the precipitated recombinant protein. Toxic effect on the culture of L929 cells was observed for the precipitate obtained by the use of ammonium sulfate and sodium sulfate. In addition, tests in L929 cell cultures infected with EMC virus showed that samples of precipitated protein by salts did not show antiviral action. In Vero cell cultures, the precipitated protein by sodium sulfate showed antiviral action for measles virus.

The point contact reaction between a Si nanowire and a Ni nanowire is reported in which the Si nanowire is transformed into a bamboo-type grain of single crystal NiSi from both ends. The reaction was investigated in-situ in an ultra-high vacuum transmission electron microscope. It is proposed that the epitaxial growth of the NiSi is limited by the dissolution rate of Ni into Si at the point contact interface and assisted by interstitial diffusion of Ni atoms within the Si nanowire. Through the point contact reaction, single crystal NiSi/Si/NiSi heterostructures have been fabricated, in which more than 12 % of strain was found in the middle Si layer, the dimension of which can be controlled down to 2 nm, overcoming the limit of conventional patterning process. This study is expected to support the realization of nanoscale electronic devices.

The government of Kenya, through the Fish Farming Enterprise and Productivity Program (FFEPP), invested heavily in the aquaculture sector between 2008 – 2011 by constructing fish ponds, providing fingerlings, fish feed and extension services. This was to increase total fish production as a means to achieve food security under vision 2030. The FFEPP increased small scale aquaculture farming in many regions of Kenya, but the economic returns are still not Abstract: Predators cause significant losses in farmed fish operations by directly feeding on the fish, causing injuries and spreading parasites and other diseases. This study assessed the type and extent of predation experienced by farmers, management practices and challenges that predispose fish farming to predation. Questionnaires were administered in October 2016 to 137 farmers in the five sub counties of Kirinyaga County. Tilapia (76%), catfish (21%) and ornamental fish (3%) were the main species of fish farmed with tilapia monoculture being dominant on earthen (56.2%) and plastic liner ponds (40.9%). Feed and water availability, predation and fish theft were production constraints while management constraints included overgrown vegetation, low water levels in ponds, and ineffective predator control. Predators were reported to cause fish loss and injuries to the fish. Piscivorous birds, otters, monitor lizards and snakes were the main predators encountered, with birds causing the greatest losses. Herons (43.8%), kingfisher (37.2%), ibis (29.3%) and hamerkop (29.3%) were the predatory birds of most concern followed by cormorants (11.7%) and egrets (11.7%). Fish predatory birds frequent the farms throughout the year and majority of the farmers (74%) reported to control them by chasing them away. Non-bird predators were controlled using fences in most areas. Knowledge on fish diseases and the role of fish predators in spreading disease and parasites is low among fish farmers and there is a need for capacity building in this regard.


We have observed that often there is a disconnect between a UML model and the requirements of the modeled processes. This gap tends to widen as models become more complex and the extraction of detailed requirements becomes more difficult. The process by which detailed requirements are extracted from a model is fairly straightforward. Not only can the technique be used to extract requirements, but, interestingly enough, the same information that is extracted can be used to generate the task list part of a project plan, as the concrete use cases identify the pieces of software that need to be implemented. The use case model is basically an acyclic directed graph, with dependencies as vertices and use cases as nodes. In order for the extraction process to work, the use case model needs to be built following certain guidelines. For example: No dependency cycles and model continuity (e.g. a single continuous directed graph).


It is often emphasized in the literature that the phase propagation of El Niño sea surface temperature (SST) anomalies along the equator changed from westward to eastward after a mid‐ to late‐1970s climate regime shift in the Pacific. Theories have been developed to explain this change of phase propagation in terms of changes in background state on which El Niño events develop. Those theories also suggest that the direction of La Niña anomaly phase propagation should have changed from westward to eastward as well. However, the direction of La Niña SST anomaly phase propagation did not change after the mid‐ to late‐1970s. Instead, La Niña SSTs continued to exhibit westward phase propagation along the equator, a feature overlooked in both observational analyses and theories. This paper highlights the asymmetry in zonal phase propagation between El Niño and La Niña sea surface temperature anomalies since 1980 and discusses the implications of that asymmetry for understanding El Niño/Southern Oscillation (ENSO) dynamics.


A once-in-a-century flood was taken place in the Xijiang River in June 2005. Continuous monitoring of DOC concentration had been carried out during, before and after this super flood. The results show that DOC variation was relatively independent of the discharge variation. Although the discharge had changed 6~7 folds, the DOC variation was less than 30% during the same period, which is very different from other rivers that DOC concentration increased quickly with the increasing discharge. DOC concentrations were in the range of 0.92~1.22 mg·L -1 at Wuzhou gauge station and 0.82~1.34 mg·L -1 at Makou gauge station during the flood period. For all those sampling stations, DOC concentrations before the flood are higher than that after the flood. Spatially, DOC concentration decreased downstream the main channel. DOC yield was very closely related to the runoff depth, suggesting that DOC yield is almost entirely under the control of the surface flow. DOC flux during the flood can be calculated by fitting a linear regression equation between the DOC load and the discharge from all measured DOC values at Wuzhou gauge station. There was 4.5×10 10 g dissolved organic carbon export during the super flood.


The objective of this study was to assess the relationship of acceptance of remote lactation consultation using videoconferencing (VC) with maternal learning styles and demographic factors among mothers of infants 蠄16 weeks old who also reported breastfeeding initiation. This cross‐sectional research design used an online survey methodology with mothers recruited from 26 randomly selected states. To date, 78 mothers have completed the survey, including responding to statements about acceptance of technology (using a 7‐point Likert scale), and completing a learning styles assessment. Preliminary analysis indicated mothers were 29.6 years old and their infants were 10.7 weeks old, on average. The sample was predominantly white (92.3%), and well‐educated (65.4% with an advanced degree) with reported incomes above 185% of the Federal Poverty Level (79.5%). Nearly half were primiparous (46.2%). Mothers generally accepted the use of VC (mean responses were all significantly greater than 4.0). No significant relationships were detected between acceptance of use of VC and any maternal demographic or learning style. Mothers in this sample appear to be relatively unconcerned about physically revealing themselves or their infants via VC, but acceptance of its use was significantly negatively related to concerns about maintaining their home as a private space. To conclude, preliminary analysis indicates general acceptance of this technology medium for lactation consultation, but providers should be aware of concerns related to home privacy.

studies published in English that directly investigate absorption of various nutrients in patients following gastric resections [3–7] . Accordingly, the current study performed by Nakamura et al. [1] makes a significant contribution to our understanding of pathophysiological consequences of different surgical procedures for reconstruction after gastrectomy and may help to guide the choice of surgical techniques. Another interesting aspect of this study is that the authors employ a modern technique for their measurements, that is a breath test using 13 C-labeled lipids. This test may have diagnostic importance beyond the specific aims of this study: 13 C-marked triglycerides are nonradioactive and can be applied safely and repeatedly, also to children and pregnant women. Breath tests using these lipids are based on the principle that intestinal triglyceride absorption requires prior hydrolysis by lipase to produce free fatty acids and monoacylglycerol. These metabolites are incorporated into micelles, absorbed, resynthesized and transported to the liver. Lipolytic hepatic enzymes subsequently release 13 C-marked fatty acids. These undergo  -oxidation which results in formation of 13 CO 2 that is absorbed into the bloodstream, transported to the lung and exhaled. The increase in 13 CO 2 concentration in breath thus correlates with intestinal lipid digestion and absorption. Accordingly, breath tests based on 13 C-labeled lipids can be used as a substitute for the unpopular direct measurement of fecal fat excretion as done by Nakamura et al. [1] in their recent study and as several other investigators did earlier [3, 8, 9] . Lipid-based 13 C-breath tests have not only been used successfully for In this issue of Digestion Nakamura et al. [1] report differential fat digestion and absorption rates in patients after subtotal gastrectomy who underwent different surgical procedures for reconstruction, that is Billroth I or Roux-en-Y. Using a noninvasive breath test they show that the Billroth I procedure allows almost normal triglyceride digestion and absorption. By contrast, the Roux-en-Y procedure is associated with a 30–40% decrease in fat absorption compared with both healthy controls and patients who have undergone the Billroth I procedure. These findings are not entirely new but rather confirm the accepted opinion that maintenance of food passage through the duodenum is of importance for efficacy of nutrient digestion and absorption in patients who have undergone subtotal gastrectomy, and that therefore the Billroth I procedure is the more physiological approach. Moreover, patient allocation to the two treatment groups appears questionable and the numbers of subjects per group are not too impressive: either Billroth I (n = 17) or Roux-en-Y (n = 14) was performed according to the surgeons' preferences in 31 patients overall and data obtained in these patients were compared with fat absorption rates of 15 healthy volunteers. By contrast, Ogoshi et al. [2] examined data of more than 1,000 patients who underwent total or partial gastrectomies because of gastric cancer. They showed that duodenal food passage reconstruction was an independent prognostic factor for improved survival rate. However, retrospective studies like this do, of course, not allow a comparison of the absorption of specific nutrients. Overall, there is an astonishing paucity of experimental Published online: June 26, 2009


The glucose phosphate isomerase (GPI) locus is closely linked to the halothane sensitivity locus in pig. The chromosomal localization of GPI in pig was confirmed to 6p12----q21 by using in situ hybridization. Of the total grains, 25 percent were located on chromosome 6, with about 65 percent clustered in the cent----q21 segment, suggesting the presence of the GPI gene on the very proximal part of the q arm. The efficiency of hybridization was found to be affected by ultraviolet irradiation of metaphases for RBA-banding before hybridization. The irradiated metaphases had higher background grains than the non-irradiated metaphases.

Both the modulation and demodulation of an OFDM signal involves a Fourier transform in which the implementation requires several multiplications. These multiplications require significant hardware resources in FPGA and ASIC devices. Significant cost and speed improvements would follow if the number of multiplications could be reduced. Our approach eliminates the multiplications and is based on three observations that are somewhat independent of each other. First, the subcarrier modulation must be QAM, including QPSK and BPSK. Secondly, an approximation of the sin/cos basis waveforms by square type pulses transforms the multiplications by sin/cos to simple additions. Thirdly, over sampling of the signals puts the harmonics of the square type pulses outside the bandwidth of the OFDM signal. Limiting the scope to QAM signals has the benefit of the input signal having only N levels which can be decomposed into binary pulses. Hence, the Fourier transform can be transformed into simple multiplies of type +/-2n, which are further reduced to logic shifts and additions. Since most practical OFDM systems use QAM modulation, this restriction is of little concern. The proposed method can be used to approximate any OFDM modulation to any degree of precision and it can be used both in transmitters and receivers.


A modified soy protein gel which has relatively high swelling ratio was synthesized by first acylating the soy protein isolate with ethylenedinaminetetraacetic dianhydride(EDTAD),followed by crosslinking with glutaraldehyde.The gels were characterized by infrared pectrophotometer(IR) and scanning electron microscopy(SEM).The acylating mechanism of the acylation and the effects of pH on gel were investigated.The experimental results showed that the swelling ratio of soy protein gels increased by acylated with EDTAD,the gel was pH-sensitive and had the function of shape memory.


The withholding periods for meat, wool and hides are 6 months after treatment with antibiotics and chemotherapeutics is double the legal period but always at least 6 months. For treatments with vitamins, minerals and anaesthetics the withholding period is the double of the legally required. For other substances the withholding period is double the legal but always at least 2 months.

The withholding periods for milk and egg is double the legal period. For substances without a set period the withholding period is 48 hours.
The KRAV standards also have a list of substances which can be used without any withdrawal period if there is no legal period. These are calcium for milk fever, agents to increase bloodsugar, carbon preparations, natural medicines, injections with vitamins and minerals, all external treatments except parasite treatment or formalin. (KRAV standards paragraph 5.4.8, 5.4.10 and 5.4.11).


Lysoplasmalogens, produced from plasmalogens by phospholipase A2, can disrupt cell membranes. Lysoplasmalogenase (Lpnase) catalyzes hydrolysis of the vinyl ether bond of lysoplasmalogen yielding an aldehyde and glycerophosphobase. We purified Lpnase from rat liver microsomes and identified the integral membrane protein as TMEM86B, a member of the YhhN family- conserved from bacteria to humans. In mammals the activity of Lpnase is very high in liver and small intestinal (S.I.) mucosa, low in brain, and undetectable in heart and smooth muscle. We tested the hypothesis that liver and S.I. Lpnase is involved in nutrient metabolism/distribution by examining microsomal enzyme activities in: 1. Adult livers during pregnancy, lactation, and post lactation. 2. Pups' livers and S.I. mucosa during early development. During gestation the units and specific activities (SA) of liver Lpnase were similar to non-pregnant (N-P) controls. During 20 days (d) of lactation (10 pups) the units of Lpnase increased by 90%; the li...


Unlike other sports, the soaring community has not yet standardized on one system for scoring its' races. This indicates a need for a scoring system analysis and design effort to determine the most accurate system for scoring each pilot's performance. The analysis in this paper shows that using the measured performance of each pilot elapsed time - as his daily score yields the highest accuracy. The svstem selects as champion the pilot with the lowest total elapsed time for the entire contest. He is the pilot who flies the total distance of the contest at the highest speed. It is recommended that organizations which sponsor sailplane races use Total Elapsed Time scoring if their objective is to score as accurately as possible.


In this paper, antenna selection algorithms of multiple-input multiple-output (MIMO) system are considered. Firstly, we analyze the existing antenna selection algorithms and the corresponding channel capacity formula. Secondly, in order to investigate the optimal performance of MIMO channel, we propose a new algorithm based on the maximum norm selection theory and matrix theory. Then we deduce the corresponding channel capacity. Finally, we design a simulation scheme to verify the performance of the new algorithm under different numbers of antennas selected. The simulation results show that with the increase of the number of antennas selected, the channel capacity increases gradually, but the growth rate slows down. Assume the scenario with five antennas, choosing three antennas is the best scheme in consideration of highest cost performance.

Short-term scheduling of a cascade of run-of-river hydro power plants is always a challenge. In the paper, a quadratic programming approach is used to solve this problem for the hydro power plant chain on the Slovenian Sava River. The approach considers head-dependency and discharge ramping constraints and takes the nonlinear connection between the water discharge and, the head and the power generation. The model has been tested using measured data on hydro flows and the technical data on the Sava River power plants.


The role played by gatekeepers who acquire external technical knowledge, translate that knowledge so as to contextualise it for their companies needs and disseminate it to key organisational personnel is of increasing importance and value to firms. This study uses a single case study to extend the existing literature on technological gatekeepers through helping to fill two theoretical gaps. Firstly, by examining how gatekeepers operate in a new functional area: a technical hardware and software product support department. Secondly, by focusing on a site where corporate information systems and repositories were used to support gatekeeping activities. This focus on new organisational and systems contexts enabled the development of new categorisations within each phase of gatekeeping activity, resulting in a revised model of gatekeeper behaviour. Two new and distinct modes of knowledge acquisition were identified: reactive acquisition to solve immediate problems and proactive acquisition that was related to emerging technologies. Whether knowledge had been validated or was provisional was identified as a new concept to be considered during the acquisition phase. The systems focus enabled a number of new forms of knowledge translation and dissemination to be categorised. Rationalised translation involved clarifying and elaborating on translations held in the corporate repository while tiered translations enabled versions of translations to be electronically available to different levels of users. While interpersonal dissemination was present the increasing reliance on information systems for dissemination diminished the traditional need for gatekeepers to expended time and energy developing social networks.


A large majority of strains of Staphylococcu,s aureus were found by Gillespie dZ; Alder (1952) to produce opacity when grown in egg yolk broth, apparently through the action of a lipase on certain triglycerides. Of the strains isolated from outpatients, 82 °/O were ' egg yolk positive ' (EY+), but only 45 °/O of those isolated from in-patients gave a positive reaction; there was a strong association between penicillin-resistance and a negative egg yolk (EY-) reaction. Parker (1958) confirmed the association of negative egg yolk reaction with penicillin resistance, and found that such strains were particularly common in superficial lesions, including wounds; strains which caused deep lesions usually showed a positive egg yolk reaction. We have tested strains of Staph. avreus isolated from burns in three periods (195S, 1960 and 1962) and from several other sources for egg yolk reaction; the association of this reaction with some other features, including phage type, antibiotic sensitiivity and mercuric chloride resistance (Moore, 1960) has been examined. The relevance of these data to the epidemiology of staphylococcal infection is discussed.

The power allocation issue for cooperative device-to-device (D2D) systems with non-orthogonal multiple access (NOMA) is examined in this paper. In cooperative device-to-device (D2D) NOMA systems, communication occurs in two phases: the direct transmission slot, or the path from the base station to user destinations, and the relaying slot, or the path from the relay (near the user), with different power allocation factors to improve the ergodic sum rate. It is suggested that power allocation considerations affect how well the ergodic sum rate performs with different decoding techniques. The decoding techniques include Reed Solomon's (RS) encoded single signal decoding technique and Reed Solomon's (RS) encoded maximum ratio combining (MRC) decoding technique. The error probability of successive decoding will increase if any errors occur during the successive interference cancellation (SIC) procedure at any user. In order to detect and correct multiple symbol errors in a Rayleigh fading environment, RS codes are used in the system architecture for error detection and correction. Through the results of the simulation, it is demonstrated that the proposed approach performs much better than the existing work for the fixed values of the power allocation parameters.


Basis sets of equally spaced Gaussian functions are used to obtain diatomic Morse and harmonic‐oscillator wavefunctions for CH and CN species. These functions are then used to obtain energy levels and eigen‐functions for model linear HCN and CH2 species with both harmonic and Morse potentials for two internal coordinates.


The research included male and female ath- letes from Belgrade, aged 18 and 19 (±6 months). All of the 32 subjects were actively exercising athletics and were in good health. The aim of the research was to es- tablish the correlation between morphological character- istics and running speed on 100 and 400 meters tracks for both sexes. By regression analyses it was determined that there is a statistically signifi cant link between an- thropometric variables and criterion variable in 100 me- ters run in favor of the male athletes, but it is also where the highest percentage of commonly shared variability namely 72% was observed. Of all of the anthropometric characteristics only Body height has been proved to be statistically signifi cantly linked to criterion variables in favor of the male athletes. The predictor system was not in no other way proved to be related to criterion in female athletes. In order to attain additional information the au- thors have suggested that further research into predictive running value and speed should include pace frequency measuring as well as considering running techniques.


Nullity is the procedural penalty that occurs in the case of a civil procedure that does not meet the conditions required by the law to be considered a validly drawn up act and which lacks the act, in whole or in part, of the effects it would cause if it were an act concluded in compliance with the conditions of validity required by law. Undoubtedly, nullity is the most important penalty for violating procedural rules, not only because it has the most destructive effect, but also because none of the existing procedural systems can be dispensed with.


This paper introduces a novel design of 4 - 20 mA output circuit about remote transmission of multiple sig- nals, it is a different circuit with the widely used at present, the circuit can realize the multi-channel 4 - 20 mA signal common ground in the distal. This new method not only can solve the problem of sampling of distal of the same com- puter, but also can save a large amount of wiring. Analyzed by computer simulation and circuit experiment, we prove that the proposed circuit hardware design method has the advantages of high precision and simple wiring, and it is able to meet the application in multi-channel 4 - 20 mA signal remote transmission.


CAPES' institutional prioritization for greater dialogue and reach of elementary education teachers resulted in the induction of 11 national network master's programs, with concentration and thematic areas directly linked to the improvement of elementary education, with hundreds of institutions involved and located in the five regions of Brazil. In this context, this article aims to highlight key aspects of the PROFCIAMB NETWORK experience, exploring challenges and lessons learned from the consolidation of the program, as a positive example of the response of Brazilian postgraduate programs to the challenges of the alignment with sustainable development. The article addresses the interdisciplinary construction of a culture of the professional master's program; the structuring and integration of the PROFCIAMB NETWORK; the interface with extension as a learning process and social impact; the resulting educational products and their usability; and finally the efforts of the NETWORK to reach regions of critical contexts regarding socio-environmental vulnerability.


Integrative solutions for the establishment and maintenance of systems for content, document and records management are outlined. A solution should embrace a range of functionality including document and Web content management capabilities, document/content review and approval management, and the implementation of recordkeeping principles and requirements. Emphasis is given to requirements specification and supplier selection.


Rotenberg's grand theory hypothesizes that the emanation cosmogony (creation myth) predominating in the West may have disseminated a unilateral physical and aggressive style of phallic-erective sexuality, whereas the cabalic contraction myth entails a bilateral space-evacuating unification model encompassing spiritual sexuality. Although Rotenberg's dichotomizing over- generalizations seem to miss the less aggressive-assertive sexual norms that may prevail in Islamic and Catholic countries and although his clinical illustrations are not sufficiently convincing, Rotenberg's metapsychology of contracting sexuality may contain new and promising directions for handling the sexually perplexing norms permeating Western societies.

Introduction A high genetic barrier to resistance to the integrase strand transfer inhibitor (INSTI) dolutegravir has been reported in vitro and in vivo. We describe the dynamics of INSTI resistance associated mutations (INSTI-RAMs) and mutations in the 3'-polypurine tract (3'-PPT) in relation to virological failure (VF) observed in the randomized dolutegravir as maintenance monotherapy study (DOMONO, NCT02401828). Methods From ten patients with VF, plasma samples were collected before the start of cART and during VF, and were used to generate Sanger sequences of integrase, the 5' terminal bases of the 3' long terminal repeat (LTR), and the 3'-PPT. results Median HIV-RNA at VF was 3,490 (interquartile range 1.440-4.990) c/mL. INSTI-RAMs were detected in 4 patients (S230R, R263K, N155H, and E92Q+N155H), no INSTI-RAMs were detected in 4 patients, and sequencing of the integrase gene was unsuccessful in 2 patients. The time to VF ranged from 4 to 72 weeks. In 1 patient, mutations developed in the highly conserved 3'-PPT. No changes in the terminal bases of the 3'-LTR were observed. conclusions The genetic barrier to resistance is too low to justify dolutegravir maintenance monotherapy, because single INSTI-RAMs are sufficient to cause VF. The large variation in time to VF suggests that stochastic reactivation of a pre-existing provirus containing a single INSTI-RAM is the mechanism for failure. Changes in the 3'-PPT point to a new dolutegravir resistance mechanism in vivo. 2 Erasmus Medical Center Rotterdam


AbstractThe site of Wadi Fidan 4 can now be definitively dated as an extended village settlement of the Chalcolithic period. Excavation in Areas A, Band D as well as surface survey of the site indicate that the entire surface of the plateau was covered by buildings. At present no full botanical or faunal reports are available, and as a result little can be said about the subsistence economy. It is clear however from the metallurgical finds and mining picks found on the site, that this community was involved in the mining and smelting of copper. The extent of metal production is probably associated with small-scale domestic production ('household' or 'cottage industry'), as has also been attested on a number of other Chalcolithic sites such as Shiqmim (Levy et al. 1987), Tell Magass (Khalil 1988) and Tell Abu Matar (Perrot 1955). Contrary to later periods, ore was not smelted directly at the mine, but was transported and processed inside the domestic settlements. This seems to be characteristic for metallu...


The social purpose of art expands its value and significance to problematize many social and political situations of day rather than limiting it to idea of aesthetic pleasure alone. African American philosophers, poets, and authors also attempt to project the issues of race and culture country is facing. They made an effort to create a strong literary framework despite various attempts at discrediting the significance of art and artists on global scale. Considering Alain Lock's idea of 'Real art or Propaganda' this paper examines true values of African American literature and takes it a step further to recognize the attempts made via literature to project their rights and preserve their culture and history. This influence never strays from true purpose of art and results in meaningful poems that appeal to human emotion and feelings on a universal level. They have historically given more weight to universal purpose of art, which is to arouse pleasure, and have utilized this as a platform to expose the systematic goal that disadvantages and presents negative picture of African American community.


Existing client onboarding and Know Your Customer (KYC) processes are typically slow, expensive and often accomplished in-person. Moreover, the current identity management models in practice deprive users from having complete control over their digital identity data. Users' identity attributes are stored on multiple centralized repositories, which often follow inadequate security policies. In this paper, we take advantage of Hyperledger Indy, a public and permissioned distributed ledger technology (DLT), to develop a digital onboarding framework based on the Self-Sovereign Identity (SSI) principles. With this framework we take a step towards tackling a number of weaknesses in current KYC processes and identity management models, while addressing the requirements associated with SSI, Privacy by Design and European Union's General Data Protection Regulation (GDPR).


Oral cancer represents one of the most common malignancies in humans. Its prognosis is still poor, despite the most recent improvements in therapies. An increasing attention is placed on the role of programmed death ligand 1 (PD‐L1) in the tumour immunity and its potential function as a marker for tumour prognosis. Whether PD‐L1 expression is a prognostic factor for the poor outcomes in oral squamous cell carcinoma is still controversial. This study aimed to investigate, through a meta‐analysis, a potential correlation between PD‐L1 expression and the prognostic outcomes in patients with oral squamous cell carcinoma.


In this study, I present a brief look at Jewish characters in the works A geracao da utopia (1992) and A gloriosa familia: o tempo de flamengos (1997) by Pepetela. Such characters leave their homeland voluntarily, but experience the difficulties and toils of every subject in diaspora, reflecting
the anguish and suffering which are illustrative of this experience both in Africa and in Europe. Illuminators of the studies discussed here are the following theorists: Stuart Hall, Home Bhabha, Moacy Scliar, Zygmunt Bauman, Elisabeth Roudinesco, among others.

A 58-year-old man presented with a single asymptomatic skin lesion on his upper back. The lesion had appeared as a small red papule and gradually enlarged in a year. He was otherwise healthy. On physical examination, a red-violaceous coloured plaque, 15 · 20 mm in size, showing a papillomatous raised centre and a brownish hue at the periphery (Fig. 1a). On dermatoscopy, there were lagoon-like areas that were partly circumscribed and partly seen as homogenous red areas. Linear white structures surrounding these lagoon-like areas were prominent. A delicate pigmented network was seen at the periphery (Fig. 1). Histological examination of a biopsy taken from the lesion showed a biphasic growth pattern, with dilated vascular spaces on the surface and narrower vascular spaces in the deeper parts of the dermis. Neoplastic endothelial cells with hobnail cytomorphology, particularly evident on the superficially located vascular channels (Fig. 2a), did not show any cytological atypia or mitotic activity. Prominent lymphocytic infiltration and slight fibrosis were present. A scattered haemosiderin deposition was seen throughout the mid dermis after staining with Prussian blue. Immunohistochemical analysis showed that the endothelial cells lining the vascular spaces were positive for CD31 (Fig. 2b). In some parts of the periphery of the main lesion, there was acanthosis with elongated rete ridges and slight lentiginous hyperplasia, and hyperpigmentation of the basilar layer (Fig. 2c,d). Based on the histopathological findings, the lesion was diagnosed as a hobnail haemangioma (HH). The originally reported characteristic targetoid appearance of HH has been shown to be variable, being an angiomatous ⁄ pigmented, nontargetoid, flat, or exophytic lesion. The lesions are often misdiagnosed, with diagnoses including haemangioma, angiokeratoma, melanocytic naevus, melanoma, dermatofibroma and even insect-bite reaction. Dermatoscopy, a noninvasive technique for the evaluation of pigmented skin lesions, may be helpful in such cases.

Analyses of radiation fields resulting from a deuterium-tritium (DT) plasma in fusion devices is a critical input to the design and validation of many aspects of the reactor design, including, shielding, material lifetime and remote maintenance requirements/scheduling. Neutronics studies, which perform in-depth analysis are typically performed using radiation transport codes such as MCNP, TRIPOLI, Serpent, FLUKA and OpenMC. The Serpent 2 Monte-Carlo code, developed by VTT in Finland, is the focus of this work which seeks to benchmark the code for fusion applications. The application of Serpent 2 in fusion specific analysis requires validation of the codes performance in an energy range, and a geometrical description, which significantly differs to conventional nuclear fission analysis, for which the code was originally developed.
A Serpent model of the Frascati Neutron Generator (FNG) Helium Cooled Pebble Bed (HCPB) mock up experiment has been prepared and the calculated results compared against experimental data, as well as the reference Monte Carlo code MCNP. The analysis is extended to a model of DEMO with HCPB blanket concept. For this model, the flux, nuclear heating, tritium production and DPA are calculated, all of which are integral nuclear responses in fusion reactor analysis. In general, a very good agreement is demonstrated for both of the benchmarks, with any discrepancies pinpointed to different physics models implemented.

Macroscopic failure of material is attributed mostly to the initial presence of micro-cracks and micro-voids and is governed by physical mechanisms at different lengthscales. In order to include discontinuity mechanisms in the material deformation and its consequence on the energy dissipations during micro-crack kinetics, a theoretical model of micro-cracked continuum is derived in this paper. The model describes a micro-crack density in terms of CARTAN constants of structure and explicitly connects the macroscopic scale to the mesoscopic discontinuities. This approach contrasts to the usual method in continuum mechanics that seeks a phenomenological description by introducing an internal variable in the constitutive laws. An illustrative example of the model application is presented for the linear ultrasonic wave propagation test. The result highlights the importance of rigorously revisiting the dynamic equation in micro-cracked solid.


Low levels of oligomer molecules are generally desirable in polymeric materials. It is known that several reactor variables can affect the oligomer distribution, and therefore it is useful to have predictive models for molecular weight distribution. The normal approach of a differential equation–based model is very complex to set up if it is applied rigorously to include all the non-Flory aspects of the step growth polycondensation and in particular the interfacial polycarbonate polymerization. In this paper, simple methods based on the Monte Carlo method and Stockmayer distribution are applied to simulate the effects of mass-transfer, unequal reactivity, and the starting stoichiometry of the polycondensing functional groups on the oligomer distribution. It is shown that these parameters can have a significant effect on the oligomer weight distribution and polydispersity of the final polymer.


Particle-In-Cell (PIC) is a method for plasmas simulation. Particles are pushed with Verlet time integration. Fields are modeled using finite differences on a tensor product mesh (cells). The Unstructured PIC methods studied here use instead finite element discretizations on unstructured (simplicial) meshes. PIC is constrained by stability limits (upper bounds) on mesh and time step sizes. Numerical evidence (2D) and analysis will be presented showing that similar bounds constrain unstructured PIC.


In this paper, a simple online identification method for single-input single-output systems utilizing the idea of sliding mode control is proposed. The method uses a simplified model with an adjustable parameter of the plant, adjusts the parameter so that the error between outputs of the plant and the model for a step input converges to zero, and gives an identification result as the adjusted parameter. Through a single identification procedure one parameter of the plant can be obtained. The simulation result shows that the method is useful for parameter identification of plants.

As timely germination of seeds is crucial to crop yield and quality, the low germination percentage for direct seeding in rice and pre-harvest sprouting during late stage of maturity have extremely adverse effects on rice production. Herein, we found that nano-silver inhibited rice seed germination while forskolin promoted this process. Germination assay showed that 20 μM AgNPs and 0.5 μM forskolin could be the optimal concentrations regulating rice seed germination. At the molecular level, an aquaporin gene, OsPIP2-1, was most highly expressed among those homologous genes during rice seed germination, and was decreased by AgNPs and increased by forskolin. Meanwhile, the activity of α-amylase and its genes expression were also inhibited by AgNPs and promoted by forskolin. Next, the germination percentage of OsPIP2-1 overexpressing seeds was significantly higher than that of wild-type, and that of OsPIP2-1 knockout seeds was dramatically reduced. Furthermore, compared with the wild type, α-amylase activity and the transcription of OsAmy3C and OsAmy3E were increased in OsPIP2-1 overexpressing seeds and decreased in OsPIP2-1 knockout seeds, indicating that OsPIP2-1 positively regulates α-amylase. Interestingly, seed germination, α-amylase activity and its genes expression in OsPIP2-1 overexpressed and knockdout lines could also be inhibited by nano-silver and promoted by forskolin. In conclusion, we propose that nano-silver and forskolin regulated seed germination by modulating the expression of OsPIP2-1 and thus α-amylase. Our results may bring new application of nano-silver and forskolin in rice cultivation.


Papillary lesions of the breast are a heterogeneous group of breast lesions that are difficult to diagnose as benign or malignant. These lesions have different morphologic features that carry variable prognostic implications for affected patients. 1 They develop as tufts of epithelium with a fibro vascular core that arborize into branching papillae and protrude into the duct lumen. The benign variety includes intra-ductal papilloma of the breast, papilloma with foci of atypia and juvenile papillomatosis of the breast. Papilloma with carcinoma in situ, papillary carcinoma of the breast, intra-ductal adenocarcinoma with papillary growth pattern are the malignant types of papillary lesions. 2 The papillary lesions in the breast can show variable appearances both clinical and radiologically. Clinically, it may present with nipple discharge with a palpable mass. On mammogram patients might have multiple bilateral lesions of different sizes and micro calcifications may be present or absent. ABSTRACT

Oribatid mites (Acari: Oribatida) are one of the most numerous and dominant groups of soil inhabitants that play an important role during soil formation and its biological processes. The paper presents a full list of oribatid mites known of Vietnam (excluding Acari: Astigmata) based on the collected and identified species as well as on literature records from 1967 to 2019. Totally, 726 plus one oribatid species belonging to 245 genera, 90 families, and 41 superfamilies, together with the specimen's data have been recorded in Vietnam. These oribatid mites species are identified and analyzed along with their distributions known according to the eight natural and man-made factors, including (1) natural region, (2) soil type, (3) climate zone caused by elevation above sea level, (4) habitat type, (5) distance to the sea, (6) climate season, (7) soil vertical distribution, and (8) oribatid body size. This will be an important scientific basis for further analysis on the relationship of the formation of oribalid mite complexes under the influence of natural & man-made factors, contributing to sustainable management of soil ecosystem in Vietnam.


An archetype that seems to link the process of the growth of the human life story recording to the process of the growth and maturation of the universal myth seeds is described. This is mostly a real story about how the author's attention energy was drawn to this archetype. The unfolding of this story took the author along different bypaths, some of them revealing, and some obviously misleading. In a way, all these ramifications seem to speak about the bearing of this archetype—Black Hen—on the classical ego-self dynamics of Advaita Vedanta, as this author understands it.


Let $\eta$ be a strictly positive submeasure on $\mathsf N$. It is shown that the space $\omega(\eta)$ of all real sequences, considered with the topology $\tau_{\eta}$ of convergence in submeasure $\eta$, is (pathwise) connected iff $\eta$ is core-nonatomic. Moreover, for an arbitrary submeasure $\eta$, the connected component of the origin in $\omega(\eta)$ is characterized and shown to be an ideal. Some results of similar nature are also established for general topological vector-lattice groups as well as for the topological vector groups of Banach space valued sequences with the topology $\tau_{\eta}$.

An integrated modeling, optimization, and control approach for the design of a microbial electrolysis cell (MEC) was studied in this paper. Initially, this study describes the improvement of the mathematical MEC model for hydrogen production from wastewater in a fed‐batch reactor. The model, which was modified from an already existing model, is based on material balance with the integration of bioelectrochemical reactions describing the steady‐state behavior of biomass growth, consumption of substrates, hydrogen production, and the effect of applied voltage on the performance of the MEC fed‐batch reactor. Another goal of this work is to implement a suitable control strategy to optimize the production of biohydrogen gas by selecting the optimal current and applied voltage to the MEC. Various simulation tests involving multiple set‐point changes, disturbance rejection, and noise effects were performed to evaluate the performance where the proposed proportional–integral–derivative control system was tuned with an adaptive gain technique and compared with the Ziegler–Nichols method. The simulation results show that optimal tuning can provide better control effect on the MEC system, where optimal H2 gas production for the system was achieved.

New types of cavitation instabilities were found in the turbopump inducers for HII and HIIA rockets. The first one is a surge mode instability with the frequency as high as 4-5 times the rotational frequency. It was found that the frequency does not depend on the flow system tested and is proportional to the rotational speed. The second one is similar to rotating stall and the disturbance rotates around the rotor at about 50% of the inducer rotational speed. This occurs only at a small cavitation number at which the head of the inducer starts to decrease. Observed characteristics of these instabilities are described first and then theoretical discussions are made.


If a compound can crystallize in more than one structural modification, this will generally also be manifested as different morphologies. In a manufacturing process crystal morphology can have a decisive impact on product characteristics such as filterability, drying time, flowability, etc. In addition, it is usually one particular modification that undergoes registration. In this lecture transcript, two examples of the influence of operating parameters on the obtained crystal modification are presented. The first example comprises a food colorant for which four crystal modifications are known. The conventional operating procedure always yielded modification D, which is characterized by extremely poor filterability. Systematic investigations have shown that in suspension each crystal modification is stable within a narrow temperature range. After solid−liquid separation no interconversion of the crystal modifications occurs. Through an appropriate change to the manufacturing process it was possible to rel...


An analysis has been made of the isomer ratio, σm/((σm + σg) for 134Cs isomers formed in the fission of 237Np by protons of energies 20–85 MeV. Compound nucleus formation was assumed up to a bombarding energy of 50 MeV, with direct interaction as the mechanism at higher energies. Values of the root-mean-square angular momentum of at 20 MeV and at 60–85 MeV bombarding energy agree with the experimental results. The results are consistent with the hypothesis that angular momentum is generated in the fission process.
