Background: Vitex agnus-castus is a deciduous shrub that is native to the Mediterranean region. It has traditionally been used in Iranian medicine. In the current study, Vitex agnus-castus Essential Oil (EO) leaves were analyzed for their chemical component as well as antioxidant and antifungal activity.
Objectives: The aim of this study was to determine the biological properties (phytochemical component, and antioxidant and antifungal activity) of Vitex agnus-castus EO from an Iranian origin.
Materials and Methods: Chemical composition of the EO was determined by using Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC-MS). Antioxidant activity of the Vitex agnus-castus EO was examined by the 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) assay, while the total phenolic content was also determined. Antifungal activity (against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krusei, Candida dubliniensis, Aspergillus flavus, Aspergillus niger, Penicillium species and Alternaria species) was performed by a broth microdilution method according to the Clinical and Laboratory Standards Institute (CLSI) protocols M27-A and M38-A for yeasts and filamentous species.
Results: Thirty-two components were identified in Vitex agnus-castus EO. The main compound was alpha-Pinene (19.48%). The total phenolic content of EO was determined as 82.26 ± 5.94 mg Gallic Acid Equivalent (GAE)/g EO. The EO exhibited significant radical scavenging activity with IC50 value of 27.16 μg/mL. The obtained EO showed significant antifungal activity. Aspergillus niger was more susceptible than other fungi (MIC: 0.78 μL/mL).
Conclusions: Potent antifungal activity, make this plant an effective replacement treatment for fungal infections or fungal strains that are resistance to synthetic antifungals.

In gynecologic oncology the ovarian cancer has become one of the leading cause of death in women. Overall prognosis for ovarian cancer patients is poor, therefore the management of this condition is restricted to expert multi-disciplinary teams (MDT) in gynecological oncology. Ovarian cancer requires accurate and complete staging so that the metastatic sites are not missed, omitting adequate staging can have significant consequences including a negative impact on survival rates. Thus the goal for survival benefit of ovarian cancer is to surgically remove all visible macroscopic tumor, because the complete cytoreductive surgery (CRS) has been shown to be associated with prolonged survival. In a remarkable number of women, complete CRS is very challenging. Especially in those with many small metastases on the peritoneal and intestinal surfaces. Primary CRS has been in practice for long time as an effective method of treating peritoneal metastases (PM) from ovarian cancer, it comprises extensive peritonectomy procedures and en bloc visceral resection. CRS is a technically challenging surgery that requires a considerable amount of skill and appropriate patient selection. Even though there are several conflicts on primary CRS but due to lack of strong evidence against comparable efficacy of primary CRS with adjuvant chemotherapy and neoadjuvant chemotherapy with interval debulking surgery, the former stays the priority, remaining the preferred method of management and which is practiced in western countries routinely. This article is a review of the CRS techniques we are currently performing for primary CRS, hereby we have described the operative details for removal of cancer in advanced epithelial ovarian cancer patients with widespread pelvic and abdominal involvement.


In order to simplify the development of autonomic and autonomous systems, we propose a model of adaptive agent built from fine-grained reusable components which implement non-functional mechanisms such as communication, mobility or adaptation skills. Each agent can dynamically and autonomously change its components to fit its runtime context, improving safety and performance in particular for open, pervasive or large-scale distributed applications. We describe a tool called Agent phi for adaptive agent modeling and we present the design of an embedded agent


Fourth-generation 8-methoxy fluoroquinolone eye drops are selected with increasing frequency as agents for the treatment and prevention of bacterial ophthalmic infections (ie, perioperative infections, conjunctivitis, and keratitis), which are occurring at an increasing rate in part because of growing resistance to second-generation and third-generation fluoroquinolones. These new topically administered ophthalmic fluoroquinolones, moxifloxacin ophthalmic solution 0.5% (Vigamox, Alcon Laboratories, Inc, Fort Worth, TX) and gatifloxacin ophthalmic solution 0.3% (Zymar, Allergan, Inc, Irvine, CA), are designed with an 8-methoxy substitution on the basic quinolone molecule so as to provide better coverage against Gram-positive organisms, including resistant strains, while maintaining coverage against Gram-negative organisms that is comparable to earlier generation agents. It is important that eye care clinicians use pharmacodynamic evidence to choose the agent that will best treat and protect their patients from serious ophthalmic infections. The 8-methoxy fluoroquinolones are bactericidal and demonstrate a broad spectrum of antibacterial activity. An additional factor to consider when choosing a fourth-generation fluoroquinolone is the combination of penetration, potency, and safety. Fluoroquinolones with higher ocular penetration characteristics are able to reach target sites, such as the corneal stroma and aqueous humor, at higher levels for greater bioavailability. Agents with higher potency [ie, lower minimal inhibitory concentrations (MICs)], greater penetration, and a wider antibiotic spectrum against known ocular pathogens, including endophthalmitis-causing organisms, are viewed as optimal. Dynamic integration of penetration and potency is important not only because the function of each is critical, but also because together these properties predict an agent's level of clinical efficacy. Safety, the third factor, is important because all ophthalmic antibiotics need to be welltolerated, nontoxic and biocompatible.


Within geography writ large, and economic geography in particular, there has been increasing interest in 'engaged pluralism' – defined by its proponents as lively and respectful engagement across theoretical, methodological, and topical lines – to increase diversity and build mutual respect among scholars. Drawing on feminist and postcolonial scholarship, we offer a sympathetic critique of engaged pluralism, grounded in a review of publishing trends in economic geography. Our findings reveal theoretical inertia around particular topics and paradigms, as well as low rates of publishing participation from women. We close with a discussion of engagement, reciprocity, and meaningful contact.


We investigate spectral properties of ordinary differential operators related to expressions of the form \begin{document}$ D^{\epsilon}+a $\end{document} . Here \begin{document}$ a\in \mathbb{R} $\end{document} and \begin{document}$ D^{\epsilon} $\end{document} denotes a composition of \begin{document}$ \mathfrak{d} $\end{document} and \begin{document}$ \mathfrak{d}^+ $\end{document} according to the signs in the multi-index \begin{document}$ {\epsilon} $\end{document} , where \begin{document}$ \mathfrak{d} $\end{document} is a first order linear differential expression, called delta-derivative, and \begin{document}$ \mathfrak{d}^+ $\end{document} is its formal adjoint in an appropriate \begin{document}$ L^2 $\end{document} space. In particular, Sturm-Liouville operators that admit the decomposition of the type \begin{document}$ \mathfrak{d}^+\mathfrak{d}+a $\end{document} are considered. We propose an approach, based on weak delta-derivatives and delta-Sobolev spaces, which is particularly useful in the study of the operators \begin{document}$ D^{\epsilon}+a $\end{document} . Finally we examine a number of examples of operators, which are of the relevant form, naturally arising in analysis of classical orthogonal expansions.


We study keys and functional dependencies in the context of partial relations that permit null values with the interpretation no information. Based on Codd's principle of entity integrity we propose the class of strong keys over partial database relations. These keys enforce both uniqueness and totality of tuples. We study the interaction of strong keys with Lien, Atzeni and Morfuni's classes of functional dependencies and null-free subschemata. For various subclasses we establish axiomatisations, linear-time algorithms to decide implication, and characterisations and computations of Armstrong relations. Interestingly, the class of general functional dependencies does not enjoy Armstrong relations over partial relations, but even the combined class of strong keys and standard functional dependencies does. We also settle various questions related to the maximal size of a family of non-redundant strong keys over partial relations.


The general subject of this panel is systems which provide for the specification, generation, and rendering of high quality synthetic images. Even though graphics has been part of the computing milieu almost from its inception, the recent phenomenal growth of graphics systems has been due in great part to technological developments. The advent of low cost, high speed storage, capable microprocessors, and high resolution displays have contributed to a myriad of graphics systems and applications. Yet, a number of significant issues concerning the design and use of digital systems for the production of realistic images remain. These include: Software environments Computing generally, and graphics in particular, have moved toward a more distributed, interactive environment. A set of problems created for computer graphics by this trend include the definition of higher level (more descriptive) primitive objects, more robust models which consider variables other than surfaces, and more synergistic human-computer interfaces. Software systems addressing these requirements should be developed together with a mechanism (standard) for the distribution of databases, rendered scenes, and application programs. Databases Recently, considerable effort has been directed toward Very Large Data Base issues. While some of this work is applicable, much remains to be done in computer graphics database research. The generation and rendering of realistic images produce enormous amounts of data, much of which is independent and not all of which is useful if restricted to a few formats. Methods for the construction and maintenance of appropriate databases are particularly important research topics. Graphics processors Mainframes of all sizes, including supercomputers, currently are being used to produce graphics images. Very few of these machines were designed with graphics product ion in mind, and fewer are effective at the task. While small computers are available in distributed environments, supercomputers are in short supply l The distribution of computational power sufficient to support real time interaction with the aforementioned database is a significant architectural issue. Nonuniformity of scene complexity, raster and frame coherence, and real time requirements argue for special purpose, multiprocessor hardware systems. The panelists will provide an overview of current work in interactive, distributed graphics environments, and will indicate some directions of research and development in modelling, workstations, software, and architecture. 1985 ACM 0-89791-170-9/85/1000-0282 $00.75


Objective To discuss the diagnosis and treatment of testicular torsion and to improve its managment. Methods The clinicaldata of 14 cases (mean age,24.5years; age range,13-48 years) of the testicular torsion were analysed retrospectively. Among them,11 cases had the lesion on the left testicle,and 3 cases on the right. The time from onset to definite diagnosis was 4h-10 d. and10cases(71.4% )were confirmed diagnosis at the first visit. Results All the 14cases were examined by operation,14cases were diagnosed correctly,8 testicles of the 14cases were removed for testicularnecrosis.6 cases were fixed and detorsed by operation. Conclusion Testicular lose is related to the torsion time closely,and delayed medical intervention render to the testicularnecrosis. Color Doppler flow imaging(CDFI) is a reliableway in diagnosis of the testicular torsion.It has important value in the early diagnosis and treatment. The operative examination is necessary when testicular torsion is high suspected or confirmed.


The administration of rabbit anti-mouse lymphocyte serum (RAMLS) plus cortisone to secondary C57 hosts prolonged the survival of A skin grafts transferred from untreated C57 primary hosts 48 hr after initial grafting. The administration of C57 anti-A immune mouse serum (IMS) to the primary C57 hosts reversed the RAMLS-cortisone induced prolongation in the secondary C57 hosts. The prolonged survival of BALB/c grafts on RAMLS plus cortisone-treated secondary C57 hosts was not influenced by administration of C57 anti-A IMS to the primary C57 hosts. A circulating lymphopenia of similar degree was noted in RAMLS plus cortisone-treated secondary C57 hosts after receiving A grafts from either IMS-treated or untreated C57 primary hosts. The administration of IMS to primary C57 hosts resulted in the rejection of a significant number of A skin grafts which had been transferred to A secondary hosts. The results support the thesis that humoral antibody bound to the graft can participate in allograft rejection, perhaps in synergism with a nonspecific cytotoxic effect of lymphocytes.


In this work we study an extension of the commonly used 5F scheme, where $b$ quarks are treated as massless partons, in which full mass effects are retained in both the initial and in the final state. We name this scheme 5F massive scheme (5FMS). We implement this scheme in the \Sherpa Monte Carlo event generator at MEPS@NLO accuracy, and we compare it for two relevant cases for the LHC: $b\bar{b} \rightarrow H$ and $pp\rightarrow Zb$.


Objective: To determine if physical factors (age, sex, weight, foot length) affected anteroposterior and intersidal weight- bearing pattern on footplate in standing posture and duration of stance phase at walking. Method: Participants were 578 healthy adults (250 men, 328 women). All participants were tested by GaitviewⓇ (Alfoots, Seoul, Korea) which measure anteroposterior, intersidal weight-bearing pattern on foot plate and duration of stance phase at walking. Measurements were analyzed to find any relations among physical factors (age, sex, weight, foot length), anteorposterior, intersidal weight-bearing pattern and stance phase. Results: The age, weight, foot length had no specific relations to anteroposterior weight-bearing pattern (r<0.2, p<0.05). Men had greater weight-bearing pattern on forefoot than women (p<0.01). The higher the age, the more midstance and the more delayed stance phase was noted (r>0.4, p<0.01). Conclusion: There was a significant correlation between sex and anteroposteior weight-bearing pattern. And there was a positive relation between age and stance, midstance phase.


Aging is the greatest non‐genetic risk factor for many diseases including Alzheimer's Disease (AD) and its mechanisms are thus increasingly recognized as potential therapeutic targets.


Today's top high performance computing systems run applications with hundreds of thousands of processes, contain hundreds of storage nodes, and must meet massive I/O requirements for capacity and performance. These leadership-class systems face daunting challenges to deploying scalable I/O systems. In this paper we present a case study of the I/O challenges to performance and scalability on Intrepid, the IBM Blue Gene/P system at the Argonne Leadership Computing Facility. Listed in the top 5 fastest supercomputers of 2008, Intrepid runs computational science applications with intensive demands on the I/O system. We show that Intrepid's file and storage system sustain high performance under varying workloads as the applications scale with the number of processes.


It is generally agreed among contemporary scholars that the modern critique of the authorship claim of the New Testament letters addressed to Timothy and Titus originated in early nineteenth-century Germany with the studies of Schmidt and Schleiermacher on 1 Timothy. However, a late eighteenth-century study by the British clergyman Edward Evanson challenges this consensus as it proves Titus to have been suspect of pseudonymity before. This 'new' perspective found in Evanson's neglected source also nuances the common assumption that from its very beginnings the critical campaign against the letters' authenticity was mainly driven by linguistic considerations.


The application of density functional theory (DFT) has been accelerating the screening and design process of alloy catalysts for the carbon dioxide reduction reaction (CO2RR), but the catalyst design principle still cannot be universally used to date because of the time-consuming DFT calculations and the unclear structure–property relationship of alloy catalysts. To address these issues, we combine machine learning methods and descriptors based on the intrinsic properties of substrates and adsorbates to develop a model, which allows rapid screening through a large phase space of alloys with the usual DFT accuracy. Our ML scheme sheds light on the size of active centers on transition metals and alloys, the effect of alloying on engineering adsorption energy, and the coupling mechanism of different adsorbates with substrates. These findings not only help us understand the structure–property relationship of alloy catalysts and the reaction mechanism of the CO2RR, but also provide a basis for the design of catalysts. This universal design framework can be extended to other catalysts and other reactions towards efficient and cost-effective potential catalysts.


The recognition of opposing and co-existing tensions within human emotional experience, and a theoretical base for reconciling apparently opposite impulses, is a fundamental part of the Hindu outlook. In this paper it is proposed that, particularly because of the flexibility of realities it affords, a re-examination of the feminine in Hindu thought can reveal possible directions for contemporary feminism. In asserting this, there is a danger of being seen to proffer undue subservience to tradition, and becoming associated with culture in its revivalist or fundamentalist forms. Yet in evading engagement with ancient ideas, lies the danger of missing a unique opportunity to empower women's lives today with concepts whose resonance with current realities belie their chronological data. Among such concepts is that of sringara rasa, one of eight essential emotional essences discussed in the ancient Indian aesthetic theory of the navarasas.


The Mammal Collection of UENF was created in 2013 to document the biodiversity of northern Rio de Janeiro, and house voucher specimens collected during field research held by professors from the university and collaborating institutions. The collection currently holds 440 physical vouchers, mostly bats, and includes noteworthy records, such as the first Promops nasutus reported for the state of Rio de Janeiro. To these physical vouchers, we recently added a digital bioacoustics collection (343 files of bat distress calls) and a camera-trap multimedia collection (2683 videos or photographs of small to large-sized mammals). In this paper, we provide an overview of these holdings, and highlight and discuss the importance of regional scientific collections, along with the fundamental role of publishing their records in online databases in order to increase their visibility and scientific use. Finally, we discuss the importance of natural history collections to society, emphasizing that improving the awareness of the general public on the role of these collections to scientific development will be crucial for their conservation over the next centuries.


There is an increasing demand for using vehicles by growing the population in modern smart cities. This rise has led to traffic jams most of the time, especially during rush hours. In order to tackle this problem different solutions have been proposed in the literature, where each one focuses on a special facet of this problem. In this paper a type-2 fuzzy predictor has introduced so that it estimates the traffic flow in different parts of the city at different times. As a result of that, prevent traffic jams will become avoidable. Also, the impacts of five important parameters that are effective in creation of traffic jams have been studied. These include age pyramid, area population, type of area, the weather, and the day of the week. General Terms Intelligent Algorithms, Prediction Systems.

Review question/objective This systematic review aims to determine the effectiveness of surgical fixation, performed after a trial period of conservative management, compared to conservative management only for unilateral spondylolysis in athletes. More specifically, the objectives are: To assess whether surgical fixation compared to conservative management of unilateral spondylolysis allows athletes to return to their regular sport more rapidly. To identify which intervention is more effective in supporting the athlete to resume pre-injury function.  Inclusion criteria Types of participants This review will consider studies in which participants are athletes with symptomatic unilateral spondylolysis of the lumbar spine. Athletes will be defined as individuals under the age of 50 competing in regular organised sporting activities. Both professional and amateur athletes will be considered participating in any type of sport. For participants to be included in the review unilateral spondylolysis has to be radiologically diagnosed in athletes with back pain using CT scanning, MRI or by Single-photon Emission Computed Tomography (SPECT) scanning. An inclusive approach will be adopted with respect to the geographical location of studies with participants from all countries and health care settings to be considered. Only studies where participants have first undergone a trial of conservative treatment prior to surgical intervention will be considered, as this is the current recommended practice. Types of intervention and comparators Surgical interventions, which attempt a direct repair of the pars interarticularis, will be considered for this review. Even though direct repair in the form of Buck's Repair is the most widely recommended surgical treatment for spondylolyis, other surgical techniques including segmental wire fixation and pediculolaminar hook screws have also been shown to be effective and will hence be included in the review.Given that this is a rare procedure and that spondylolyis procedures are only completed in specialist spinal surgery units it is likely that the surgeries will only be performed by a highly qualified specialist and therefore no studies will be excluded on the basis of who is performing the surgery.  The comparators are the conservative treatments commonly used to treat unilateral spondylolyis in athletes and allow return to sport including, but not limited to rest, activity modification, bracing, lumbar stability exercises, pharmacological treatment and physical therapy. Types of outcomes The primary outcomes of interest in this review are return to sport, length of time before return to sport and level of sporting activity after treatment. With respect to measures of outcomes, a yes/no response will indicate return to sport, which may be gathered by patient observation or report. All objective and subjective measures of time to return to sport and level of post treatment sporting participation/activity level will be considered.  Overall function and pain are secondary outcomes for the review.


For most of the universities worldwide, online learning was one of the efforts to minimize the spread of Covid-19. However, today, almost two years after this dramatic experience in all aspects of living, working and learning/studying, as the global trend in online learning remains upward. Although some higher education institutions worldwide were shifting in the direction of online content delivery and online learning and before Covid-19, the pandemic both accelerated and forced a more universal move in this direction especially in developing countries. In the country, the online learning was implemented without planned prior preparation. Our educational system faced a state of emergency caused by the pandemic. As such, the experience and lessons learned from this forced adoption of online learning in the country is exceptionally valuable as basis for further improvement and leveraging the potential of online learning. The goal of this paper is to investigate the determinants of students' behavior in relation to the use of online learning in higher education in the country, on the sample of the Faculty of Economics, Ss. Cyril and Methodius University in Skopje. The basis for the research model in this study is the original Unified Theory of Acceptance and Use of Technology - UTAUT model. This fundamental model examines the crucial predictors/factors of technology adoption like: performance expectancy, effort expectancy, social influence, facilitating conditions, behavioral intention and usage behavior (acceptance). For the purpose of this research, the basic UTAUT model is extended by additional construct - perceived enjoyment recognized as important factor regarding young population technology adoption. Data were collected from more than 120 undergraduates during April and May 2022, while online learning was still undergoing. This research provides relevant theoretical and practical implications by elaborating that the analyzed factors are critical in students' behavior in relation to the use of online learning in our country context.


Most businesses rely on a significant stack of software to perform their daily operations. This software is business-critical as defects in this software have major impacts on revenue and customer satisfaction. The primary means for verification of this software is testing. We conducted an extensive analysis of Java software packages to evaluate their unit-testability. The results show that code in software repositories is typically split into portions of very trivial code, nontrivial code that is unit-testable, and code that cannot be unit-tested easily. This brings up interesting considerations regarding the use of test coverage metrics and design for testability, which is crucial for testing efficiency and effectiveness. Lack of unit-testability is an obstacle to applying tools that perform automated verification and test generation. These tools cannot make up for poor testability of the code and have a hard time in succeeding or are not even applicable without first improving the design of the software system.


In this work we demonstrate the use of a high resolution non-contact scanning microwave microscope for characterization of printed resistors. The resonant microwave probe operates at a frequency of 5.73 GHz and it is based on a dielectric resonator coupled to a gold-coated tungsten tip with radius of 200 μm protruding from a cavity wall. Direct print additive manufacturing was used to produce the resistive films. Non-contact measurements of the resonant frequency fr and quality factor Q of the resonant microwave probe at a standoff distance of 20 μm were performed. Quality factor images were obtained over a scan area of 160 μm × 1670 μm in steps of 10 μm. Measurements reveal that Q varies from 214 to 233 over the studied region. In this work, variations in Q are associated with non-uniformities on the resistor surface. The quality factor of the probe was also acquired as a function of the tip-sample distance and measured data was fitted to a polynomial equation. We converted Q images to sheet resistance i...


The invention relates to a strength member (8) for elastomeric products, particularly for the belt bandage (7) of pneumatic vehicle tires, wherein the strength member (8) has a rectilinear core (9) and said core (9) surrounding the sheath (10), wherein the core (9) is formed from precisely one textile yarn erstverdrehten each other fibers and said jacket (10) comprises high modulus textile filaments (12). Object is to provide a rigid carrier, which increases the durability of the elastomeric product. In addition, the strength member should be characterized by a stress-strain behavior when using the reinforcement layer, particularly as a belt bandage in vehicle tire offers a smooth tire construction including vulcanization and the tire still provides better speed and rolling resistance properties. The object is achieved by the yarn of the core (9) is a niedermoduliges staple fiber yarn from fibers (11) of limited length, which are first-twisted together, and by the high modulus continuous filaments (12) of the shell (10) the core (9) in about helically wind around.


An extended analytical solution to the rate equations for the branching‐chain reactions of the H2–O2 reaction under shock‐tube conditions is presented. Together with an experimental determination of the detection threshold for OH of the Bi (3067) line‐absorption method used in earlier experiments, this solution allows quantitative comparison of calculated and experimental ignition delays. It is shown that calculation and experiment can be brought into agreement with slight modification of chain‐reaction rate coefficients deduced from the results of other studies of the H2–O2 reaction. The essential role of the rate of chain initiation by a path other than diatom dissociation in determining the ignition delays is brought to light. Rate‐coefficient expressions for the chain reactions are suggested and supported.


Brown adipose tissue plays a thermoregulatory role influencing energy balance in experimental animals and possibly also in humans. In the present study we have reevaluated whether brown adipose tissue may contribute to the development of cancer cachexia in non‐growing mice bearing an isogeneic tumor. Interscapular brown adipose tissue mass decreased by 20% in freely‐fed sarcoma‐bearing mice housed at room temperature. Increased mitochondrial density and increased oxidation rate of acetate at low acetate concentrations were found in brown fat from sarcoma‐bearing mice, while the oxidation capacity was unchanged compared with that of freely‐fed controls. Metabolic and morphologic changes in brown fat from sarcoma‐bearing mice were similar to those found in weight‐paired controls, which had experienced the same loss of body weight as the tumor‐bearing mice. Selective and non‐selective B‐receptor blockade and surgical removal of interscapular brown fat before tumor implantation did not influence the nutritional state of freely‐fed tumor‐bearing mice. Injections of noadrenaline caused a proportionately lower increase in oxygen uptake in tumor‐bearing animals than in freely‐fed controls. Exposure to cold (+5° C) doubled food intake and led to hypertrophy of brown fat in both sarcoma‐bearing mice and control animals. Tumor growth was lower although not statistically different in animals housed at +5°C compared with animals housed at +25°C. It is concluded that brown adipose tissue from sarcoma‐bearing mice could not account quantitatively for the host wasting in tumor‐bearing mice housed at room temperature.


Liparidids constitute a speciose cottoid family that is distributed worldwide. Recent studies show that, contrary to previous belief, many species occur on the west coast of South America and in the Antarctic Ocean. Liparidid material from the coast of Chile between the intertidal and the mid-depths of the continental slope includes four genera and 11 species. Of these, two are new species of Paraliparis: Paraliparis molinai and P. merodontus. One, Eknomoliparis chirichignoae, represents a new genus and species. Four of the seven described species have been reported only once: Careproctus crassus, C. pallidus, Liparis antarctica, and P. debueni. One undescribed species is known from a single damaged specimen. The remaining three species, C.falklandica, P. anarthractae, and P. eltanini, are better known. In this paper we review the known material, describe the new genus and three new species, redescribe and discuss poorly known early material, diagnose the remaining species, and provide an inclusive key.


The Klein-Gordon equation for a scalar field sourced by a spherically symmetric background is an interesting second-order differential equation with applications in particle physics, astrophysics, and elsewhere. Here we present solutions for generic source density profiles in the case where the scalar field has no interactions or a mass term. For a λφ 4 self-interaction term, we provide the necessary expressions for a numerical computation, an algorithm to numerically match the initial conditions from infinity to the origin, and an accurate guess of that initial condition. We also provide code to perform the numerical calculations that can be adapted for arbitrary density profiles. (cid:135)


Few African sailors boarded transatlantic slave ships, but their importance exceeded their numbers. They played important roles in the operation of the slave trade, especially along the African coast during slave acquisition. Based on Portuguese ship licenses, this study discusses the presence of African enslaved seamen on board Portuguese vessels. Although in captivity, slave sailors enjoyed some degree of freedom denied most slaves during the Atlantic crossing. Their language skills allowed them to work as interpreters, mediating interactions between slave captains and African merchants, as well as between slaves under the deck and the crew. African crew members were active participants in the transformation of the Atlantic world.


Development of the range of RB 211 engines for two, three and four‐engined aircraft is characterised by optimisation of each of the types according to a particular application. At the same time, an advance in one powerplant which will clearly be of value to others is embodied over the range, so that a continual programme of product improvement is maintained.


Zoomed ROI reconstruction is a natural challenge for iterative reconstruction (IR), since the reprojection step requires knowledge of the entire object attenuating the x-ray beam. In contrast, analytic FBP can reconstruct images within the zoomed ROI without the need of the full FOV reconstruction, provided projection data is not truncated. To overcome this challenge in IR, the following approaches have been suggested: 1) Remove the part of the projection data corresponding to the outside-of-ROI part of the image volume. 2) Use two volume grids, one for full FOV and one for desired ROI. In the case when the size of desired ROI becomes very small, resolution of the fine grid becomes dominated by the coarse grid, and small features cannot be resolved. Our approach is inspired by multi-resolution framework. Image reconstruction is done in several steps. At each step we reduce the size of reconstruction FOV, for example by half, thus refining the scale, since matrix size remains constant. The proposed approach provides the following advantages compared to the standard 2-grid approach 1) Spatial resolution is preserved in zoomed ROI reconstructions. 2) Computational burden and computer memory requirement are reduced. 3) Parameter optimization is simplified, since only one volume is reconstructed at each iteration.


Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) have been used to characterize the nanowear of ZnO, the interdiffusion of Al/Ti films grown on SiC, contamination formed during the fabrication of MEMS (Micro-Electro-Mechanical Systems) switches, and the surface composition along a crack in an aluminum alloy. The relatively high spatial resolution of AES is very useful for the surface compositional analysis of MEMS devices and can often provide additional information about surface chemistry. When spatial resolution is not a problem, XPS usually provides superior quantitative analysis as well as more chemical information about the surface composition.


We propose an adaptive channel allocation algorithm applicable in multi-carrier cellular CDMA systems. In our method, traffic channels are assigned to a mobile user based on cell traffic load and user mobility pattern. Depending on the mobility pattern (and the probability of moving to a neighboring cell), the algorithm selects the best-suited carrier (for the mobile), which may not always be the least loaded carrier in the cell. Performance measurements include percentage of calls blocked, percentage of calls dropped, percentage of supported call duration (in relation to its total required duration), and call quality (average number of legs supported during soft handoff). Simulation results show that the algorithm offers significant system performance improvements over hashing based algorithms and is suitable for next generation cellular system.


Iberian ham is a high‐quality food that is traditionally produced from black pigs that are native to the Iberian Peninsula. The taste and texture of Iberian ham are largely determined by its lipid content and composition. In this work, low field 1H‐NMR spectroscopy was used for the first time to analyze the lipid profile of Iberian hams as a determinant of quality. The quantification of fatty acids (FAs) is readily obtained from the integration of the spectral peaks. The FA profile is highly influenced by the diet of the pigs, with monounsaturated FAs being more prominent in hams from acorn‐fed pigs. The NMR data was analyzed using a sparse partial least squares multivariate data analysis multivariate model, which allowed for the categorization of Iberian hams according to the pig's feeding regime. The main variables on which this classification is based are FA unsaturation and triacyl glyceride hydrolysis. On the other hand, there are no significant differences in the phospholipid content of the different categories of Iberian hams as determined by colorimetric and inductively coupled plasma optical emission spectroscopy methods.Benchtop 1H‐NMR spectroscopy has thus revealed as an operationally simple and powerful tool for the lipid analysis and classification of Iberian hams according to the diet of pigs.


Heat exchangers are a device used to transfer heat between two or more fluids. Cold water is commonly used in heat exchangers. But the heat transfer rate of the heat exchangers using water is less. Our aim is to improve the heat transfer rate. So, instead of cold water, we are using Nano fluid along with water. Nano fluids have improved thermal properties and heat transfer rate. Nano fluid contains metallic or non-metallic nano powder with a size of 100 nm in base fluid. We designed a CATIA model and imported the geometry in ANSYS software. After importing, we completed meshing process. Next, in setup, we selected material for shell and tube. Then we selected Nano fluid as the heat transferring medium. We provided boundary conditions to the heat exchanger. This gave us the result. From the result, we calculated the efficiencies of heat exchanger using water, aluminium oxide and copper oxide respectively. By comparing, we observed that the efficiency of copper oxide is greater than aluminium oxide and the efficiency of aluminium oxide is greater than cold water. Thus, we conclude that Nano fluids increase the efficiency of heat exchanger.


The objective of the present study was the psychometric evaluation of the Tripartite Influence Scale (TIS) among Brazilian youths of both sexes. The sample consisted of 475 undergraduate students aged between 18 and 29 years old (M = 20.8, SD = 2.0). We evaluated the construct validity (exploratory factor analysis), convergent validity (correlation between the scores of the TIS and measures of body satisfaction), reliability (Cronbach's alpha) and reproducibility (test-retest). The instrument presented factorial structure composed of three factors replicating the original scale factors, significant negative correlation for measures of body satisfaction (> -.21, p <.001), and showed no difference between the scores on test-retest reproducibility. It was confirmed TIS's psychometric properties, and its use is indicated for young Brazilian people.


The debate on whether price movements in commodity markets are determined by changes in physical supply and demand fundamentals or by the speculative effects of financial investors seems to find some element of agreement on one particular point: the need for increased transparency and improved information on futures markets and physical commodity markets. This discussion paper provides an assessment of the current situation with regard to availability of information on physical commodity markets, pointing to some of the existing information gaps and areas for improvement. The paper presents a comprehensive account of the different information sources for physical commodity markets (including their websites), and could therefore be considered a practical information tool in itself, of use to different stakeholders interested in knowing about developments in these markets.


Aim: The main aim of the work was to determine whether the selected clients coming for gynecological operating rooms in the hospital Pardubice region for gynecological operation lasting at least 90 minutes in hypothermia. Background: The value of body temperature is ranked among important indicators of the current state of man. Body temperature determines the state of equilibrium, which is due to heat build-organism, receiving heat from the environment and dispersing heat from the body. Methods: We made quantitative research, when the recording sheet own compositions have been recorded by us defined data (initials and year of birth, surgical approach, body temperature at predetermined intervals, weight, height, the person who measured the body temperature of the clients and undertake preventive measures against hypothermia ). The respondents comprised 50 women of different ages and BMI, which underwent gynecological operation vaginal or abdominal, which lasted more than 90 minutes. Results: Of the 50 clients who underwent gynecological operation lasting more than 90 minutes, had 30 of them (60.00%), while on the operating room hypothermia. Women who ranged in normal BMI group were a total of 16 (32.00%) of all those involved. In 14 of them (28.00%) with hypothermia while on gynecological operating theater. The group of overweight BMI included 16 clients (32%), hypothermia occurred in 9 of them (18.00%). Obese belonged to a group of 18 women (36%) of all monitored clients. In this case, hypothermia occurred in 5 of them (10.00%) In operations, when the actual treatment lasted 90 minutes, hypothermia occurred in 17 (34.00%) cases. Conclusions: In our case, the hypothermia occurred in 30 of the 50 clients, which are quite alarming figure because hypothermia can lead to subsequent postoperative complications and decreased postoperative reconvalescence.


Abstract In 2007 the Swiss Federal Commission for NRBC Protection released a disaster management plan for coping with the aftermath of radiological dispersal devices. This paper summarises the basic concept and outlines the relevant bodies and agencies as well as their responsibilities. It also sets out the strategy to monitor radioactive contamination and the measures to prevent public radiation exposure.


Gaseous hydrocarbon fuels were reformed by DBD plasma and their sooting characteristics were observed. Laser extinction data shows that integrated soot volume faction (F v ) in laminar diffusion flame is greater when pure or nitrogen-diluted methane, ethylene and propane is reformed by plasma, while F v is smaller when the fuel and air mixture is reformed. Gas chromatography results show that C₂, C₃, or C₄ hydrocarbons and hydrogen were generated by plasma, which alters soot formation and oxidation characteristics in the flame.


The PI3/Akt/mTOR kinase signaling pathway is a major signaling pathway in eukaryotic cells, and dysregulation of this signaling pathway has been implicated in tumorigenesis and malignancy in several cancers including prostate cancer. We assessed the effects of combination PI3K pathway inhibition on the efficacy of PDT in human prostate tumor cell line (PC3) and SV40-transformed mouse endothelial cell line (SVEC-40). Combination of PDT and BEZ 235 (BEZ), a pan-PI3/ mTOR kinase inhibitor additively enhanced efficacy of sub-lethal PDT in both cell lines. The combination of the pan-PI3/ mTOR kinase inhibitor LY294002 (LY) with PDT also enhanced efficacy of PDT in PC3 in an additive manner but synergistically in SVEC. In order to determine the mechanism of enhancement of efficacy, we assessed apoptosis and autophagy following PDT. PDT-mediated apoptosis was enhanced in endothelial cells, by both BEZ and LY rapidly after treatment. Compared to SVEC, PC3 cells are apoptosis-deficient and apoptosis was not significantly enhanced by either LY or BEZ. However, lethal PDT of PC3 cells induced a delayed autophagic response which may be enhanced by combination, depending on PI3K inhibitor and dose.


The secretome of mesenchymal stem cell offers a series of immuno-regulatory properties and is regarded as an effective method of mitigating secondary neuroinflammation induced by traumatic brain injury (TBI). The secretome of adipose-derived MSCs (ASC-ST) was collected under hypoxia conditions. Proteomics data were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and concentrations of major components were tested. Following the TBI caused by an electric cortical contusion impactor, rats were injected ASC-ST via caudal veins for 7 days. The neurological functional prognosis of TBI rats was significantly improved, and the vasogenic edema of brain tissues that was measured 14 days after TBI was relieved by ASC-ST, corresponding to brain water content levels. ASC-ST ameliorated TBI-induced neuroinflammatory environments that caused the edema, the apoptosis of the neural cells, and the nerve fiber damage by increasing the number of M2 phenotypes present while reducing the number of M1 phenotype microglia present. Furthermore, IL-6 and TNF-α levels were reduced while TGF-β and TSG-6 levels were increased after secretome treatment. Altogether, ASC-ST is capable of improving neural functioning by modulating TBI-induced neuroinflammation and its related secondary insults. ASC-ST may be one of the most promising candidates for regulating the secondary inflammatory reactions of central nervous systems for clinical use.

The article reveals the results of the study of Ukrainian-Japanese relations and their influence on the development of the Ukrainian state. Relationships between two countries are dynamically developing. The legal framework of two countries includes fifty four documents. It is typical for Ukraine-Japan relationships to follow the principle of human security/ according to the principle the main object of politics is a person, not the state. Adherence to these principles is traced in Japan's foreign policy, assessment of domestic devel-opments and Ukrainian issues in the international arena, as traced in the 2004 statements on the Ukrainian presidential election, the 2009 Ukrainian-Russian gas war, and the Revolution of Dignity. Another step to mutual trust and friendly relations is being made through official meetings between Japanese and Ukrainian statesmen and politicians. Since 1994 representatives of both countries have made official trips and held negotiations that paved way for developing two side relationships. There is a functioning Association «Japan-Ukraine» in a Japanese Parliament responsible for the relations with Kyiv. Similar group has been working in Ukrainian Parliament which is in charge of relations with Japan. Japan's foreign policy regarding Ukraine is a part of the general strategy applied in formation of the so-called «The Ark of Freedom and Prosperity in Euroasia» and, at the same time, one of the foundation principles of Japan foreign policy. According to this approach Tokyo is eager to sup-port formation of the circle of successful and prosperous countries. Officially providing aid, Tokyo helps to strengthen democracy, develop infrastructure and legal framework considering historic and cultural development of the country. "Kusanone" is the main assistance program to Ukraine, under which up to 15 projects are implemented annually. Thus, since 2004, Japan has implemented 103 projects worth a total of $ 7.5 million. Through the Kusanone projects, Japan also indirectly contributes to Ukraine's development by providing financial and technical assistance through intergovernmental agreements, as well as grant projects for international non-governmental organizations to strengthen the role of democratic institutions, economic and administrative reforms, and infrastructure development.

Engaging the 'Geographies of Dissociation' in the spirit of constructive dialogue and debate, this commentary recognizes its contributions and raises issues and questions relating to the potential and perils of pluralism, value, the material and the symbolic, and uneven geographical development and its politics. Building on the claim that pluralism needs to be a means to greater explanation and understanding rather than an end in and of itself, it argues for a more balanced culturally and politically grounded economic geography.


The toad, with the mouth kept open by means of a stick, reveals marked changes in the muscular tonicity of the limbs and in locomotion. Righting reflex is easily inhibited and can be inhibited for quite a long time. However, it preserves its defence reaction to a more or less noxious stimulus. The mouth may be kept open in this manner for over 2 hours without any deleterious effect to the animal. After removing the stick, the mouth is voluntarily closed and the animal returns to its normality in a few minutes. When the mouth of the toad is kept widely open by means of a relatively long stick, the electroencephalogram recorded with needle eletrodes inserted under the skin overlying the two hemispheres appears reduced in rate and amplitude. This change in pattern is usually more marked when the animal remains in supine position, and less so when the mouth is not opened to its maximum. It seems, therefore, there is an inhibitory process of different degrees in the central nervous system. This simple manoeuvre of keeping the mouth open by means of a stick may be useful in future studies in which the toads are to be immobilized for longer or shorter periods without any deleterious effect.


This paper presents how routers can manage large amount of data packets as routers exchange information with each other to find the best possible route to a destination thus graphs represent a more general class of structures than sets, sequences, lattices and trees. Since on web heavy range of information is represented by a graph as in social networks so modelling a sophisticated network by statistical analysis requires efficiency in routing packets within an autonomous system hence this approach here focuses on how routers can upgrade their configuration to exactly route the frequently occuring data packets within a homogeneous network. General Terms RTB-FP–Tree graph representation of a homogeneous network, improved algorithm and network statistics based forwarding table.

Abstract A series of one-step urea-urethan cast elastomers has been prepared employing various diisocyanates with 3,3′-dichloro-4,4′-diaminodiphenylmethane and 3,3′-dichlorobenzidine. The effects of diisocyanate structure are not as pronounced as those previously reported for prepolymer systems. Significant variation in stress-strain properties may be obtained, however, depending on the molecular weight and the backbone structure of the polyglycol. A complex catalyst situation, arising from differences in reactivity of the diisocyanates, may also affect these properties considerably as a result of improper balance of reactions during chain buildup. The use of a newly available diisocyanate, "mixed isomer" MDI, which affords high strength elastomers while eliminating safety hazards and cumbersome handling techniques, is also described.


The contemporary genre of climate fiction can be thought of as the stories we tell ourselves about our changing global climate. Thus, it is important to understand the dynamics behind the production and circulation of those stories. This article first reviews how geographers have begun to analyze these questions with regard to climate fiction. Some analyses reflect a certain "ideology critique," similar to Fredric Jameson's theories of allegory, while others foreground the agency of fiction in prefiguring political futures. This article also shows how recent suggestions that Gillian Hart's theorization of articulation bridges the classic disciplinary divide between historical materialist and poststructuralist accounts, in addition to work in the subfield of literary geography, are relevant in this case. After discussing examples of "ideology critique" and what I term the "fiction-as-change-agent" critique, I examine how theorizing articulation can help show the dialectical relationship between ideology and fictive agency in the context of contemporary climate fiction. I do this in reference to two recent works of climate fiction: Amitav Ghosh's Gun Island (2019) and Lydia Millet's A Children's Bible (2020).


Among various renewable energy technologies, wind power is one of the most popular one due to its multiple benefits. Wind power is produced by wind generators, permanent magnet synchronous generator (PMSG)-based wind generator is popular for its advantages such as gear-less, high efficiency, and low cost. However, because of the stochastic nature of wind, the effective control of PMSG-based wind generator is a challenging task. In order to address this issue, in this paper we propose an optimal control method for control of PMSG-based wind generator. In this method, model predictive control (MPC) approach is utilized, which enable the optimal control of control of PMSG-based wind generator. In addition, considering the highly uncertainty in wind speed, we introduce the concept of soft-target control, which makes the proposed control method more practical. Simulation results validate the performance of the proposed control method.

The paper describes a brushless, self-excited alternator in which the reverse-rotation component of the armature m.m.f. is used to increase the excitation current as the load is increased. The excitation scheme is power-factor sensitive, since the increase is greater as the load becomes more inductive, and the voltage regulation is within that normally required from single-phase self-excited machines. An analysis is presented in which the nonlinearities essential for stable operation are discussed, and close agreement between predicted and measured load characteristics is obtained.

At the same time by being an example of a design that complements La Carolina Park by subtracting as less as it can possible can of its natural green areas and making them a part of the interior design. Therefore, by being located in a strategic position in the city near cultural landmarks it takes advantage of the lost potential of the old museum, the botanical garden and the constant user activity of the park and its urban area...


A Fourier transform infrared (FTIR) isotopic study of the C4H (butadiynyl) radical produced by trapping the products from the vacuum ultraviolet photolysis of diacetylene (C4H2) and 1,3‐butadiene (C4H6) in solid argon at 10 K has been carried out in the midinfrared from 400–3900 cm−1. A variety of carbon‐13 and deuterium substituted C4H2 and C4H6 parent molecules were used to produce various isotopomers of C4H. On the basis of their isotopic behavior two absorptions at 3307.4 and 2083.9 cm−1 have been assigned to the ν1, C–H stretching and ν2, C 3/4 C stretching modes. The previous identification of the other C 3/4 C stretching mode, ν3=2060.6 cm−1, which was based on the effects of deuteration, has been confirmed and the corresponding frequencies for various 13C‐substituted isotopomers have been measured. The following frequencies have been obtained for ν1, ν2, and ν3 for C4H isotopomers: 3307.2, 2078.9, and 2023.8 cm−1 for H–C 3/4 C–C 3/4 13C; 3307.2, 2069.9, and 2032.5 cm−1 for H–C 3/4 C–13C 3/4 C; 330...


This article discusses the problematics of trauma, memory formation and the diverse forms of the uncanny (unheimlich) found in prison writings by Everardo Dias, Graciliano Ramos, Dyonelio Machado and Flavio Tavares, referring to different moments of suspension of rights and authoritarianism in twentieth century Brazil (the marshal law imposed in 1922-1926, followed by the Vargas and military dictatorships). In comparing these works, I reflect on questions crucial to the testimony of violence, such as the difficulty of its symbolization and the importance of the construction of memory and of the differential repetition through writing.


Nano-selenium was prepared using carboxymethyl chitosan(CMC)as template by reaction of selenious acid with ascorbic acid.The effects of reaction time,reactant concentration and temperature other experimental conditions on particle size and morphology of product were studied.The products were characterized by UV-absorption,IR spectra,TEM and XRD.The results showed that the reaction system at 40~60℃for 120min with CMC mass fraction 0.5%,and mass ratio of ascorbic acid to selenious acid 4∶1,the red and uniform selenium is obtained.Its average size is about 18nm.


The microstructure and heat treatment behavior of biological aragonite in different layers of limnetic shell(Hyriopsis Cumingii) and its cultured pearl were systematically observed and comparatively investigated by using Fourier transformation infrared spectroscopy(FTIR),the field emission-scanning electron microscopy(FE-SEM),high-resolution transmission electron microscopy(HR-TEM),X-ray diffraction(XRD) and thermo gravimetric and differential thermal analysis(TG-DTA).Furthermore,the reasons of frequency shift and heat treatment behavior of aragonite in different layers and pearl were discussed.The result of XRD shows that the freshwater cultured pearl and three shell layers including inner ligament,outer prismatic and inner nacreous layers were uniformly aragonite.In addition,different heat treatment behaviors shown in the aragonite in pearl and different shells are attributed to particle size and the content of organic matrix in different layers of shell and pearl.


In this issue of the journal we present four papers, two of which are in the field of human resource management, one concerns police misconduct in Eretria, and the final paper concerns the relational dynamics between the firm (and its brand) and the consumer. The first artcile is by Achakul and Yolles. Its interest lies in personality trait theories and motivation. Personality characteristics provide a basis for the anticipation of patterns of behaviour, and hence are of interest to human resource management departments. Understanding how motivation plays a role in personality is therefore useful. Achukul and Yolles draw on cybernetic knowledge theory and develop a trait model that enables the exploration of personality based motivation. The research suggests that personality traits are not limited to bipolar relationship, but that the traits also maintain intimate relationships. The next paper is also human resource centred, and Labedz undertakes an exploration of workforce diversity in relation with retirement security. Here he proposes a 'Right Work Force Model' that can offer a simplified framework to integrate a set of human resource management factors with operational considerations. In his diversity management context, Labedz recognizes that his model is able to respond to questions relating to a number of interests, including worker employability. The paper recognizes that some equal employment opportunity andworkforce diversity gains become constrained or unexpectedly reversed because of long-standing systemic structural forces that are beyond the control even of employers. An argument is put that the 'perfect calm' of diversity management opportunities arises. The third paper takes a turn away from human resources. Desta is interested in police integrity and misconduct in Eritria. The results of a survey called relating to police conduct and misconduct, disciplinary processes and the willingness to 'tell' on colleagues. The results suggest a direct relationship between the degree of seriousness that an offence has with the likelihood of sever disciplinary action. The final article in this issue is by Dominici, Basile and Palumbo, and takes an altogether distinct orienatation. It concerns the relational dynamics between the brand and consumer. They offer a conceptual framework that takes a cybernetic perspective, in which Consumer Culture Theory offers a part by considering the individual as an active participant of the branding process. They develop beyond the Consumer Culture Theory which is individual based, and centre on a systemic approach in which the individual is one element of a plurality. They then consider the viability of this system through the maintenance of symbolic and cultural relationships thae exist between the firm (and its brand) and the plural consumer, and their process of co-evolution.


A series of hydrogenated diamondlike carbon films grown using plasma-enhanced chemical-vapor deposition is systematically studied as a function of source gas composition using transmission electron microscopy. The structure of the films is examined at three distinct length scales. Both plan-view and cross-sectional studies are undertaken to reveal any large-scale inhomogeneities or anisotropy in the films. The degree of medium-range order in the films is measured by performing fluctuation electron microscopy on the plan-view and cross-sectional specimens. Electron-energy-loss spectroscopy is employed to measure the mass density and sp{sup 2}:sp{sup 3} carbon bonding ratios of the samples. Thus, inhomogeneity as a function of depth in the film is revealed by the measurements of the short- and medium-range orders in the two different sample geometries. Soft, low-density diamondlike carbon films with low coefficients of friction are found to be more homogeneous as a function of depth in the film and possess reduced medium-range order in the surface layer. We find that these properties are promoted by employing a high hydrogen content methane and hydrogen admixture as the growth ambient. In contrast, harder, denser films with higher coefficients of friction possess a distinct surface layer with a relatively elevated level of carbon sp{sup 3}more » bonding and a higher degree of medium-range order. The structure of the films is examined in the light of the energetics of the growth process. It appears that a high flux of penetrating hydrogen ions modifies the surface layer containing the remnant damage from the carbon ions, homogenizing it and contributing to a lowering of the coefficient of friction.« less


Stability is one of the important aspects of life, our everyday systems — the permanence of things. When this stability gets disturbed, instability is produced. Sometimes this instability is desirable, and sometimes not. In the crude oil extraction process, fluid instability is observed. Saffman and Taylor explored the concept of the Hele-Shaw cell to study these instabilities. The Hele-Shaw cell involves a high viscous fluid sandwiched between two parallel plates, and the low viscosity fluid enters from the periphery. Insertion of low viscous fluid into a high viscous fluid generates a pattern that is a resemblance to a finger. This phenomenon is called viscous fingering. In this paper, the authors control the instabilities and mimic patterns available in nature. These instabilities can be controlled by controlling one of the fluids in the cell. Here authors control the low viscous fluid (air) by providing anisotropies. Anisotropy means providing holes and slots on any plate of the cell. This anisotropy guides air to interact with high viscous fluid at some desired location. The authors further studied the effect of size, position, the orientation of these holes and slots on the viscous fingering exhaustively.


A NEMIA is a term ordinarily used to denote a diminution in the oxygen-carrying capacity of the blood which directly implies a lowering of the hemoglobin content. There are different types-the socalled secondary anemia, pernicious anemia, sometimes called primary anemia, and hemolytic anemia. At the present time much stress is laid upon the right foods to remedy the anemic condition. Encouraging results have been obtained in a number of studies made in our universities


The Great Fire of London in 1666 is well-known to us. At that time the most area of the City was burnt and collapsed by the fire. But it is also true that the Great Fire was served as a turning point at which London began to be changed from medieval city to modern one. How had London been redeveloped and re-built after the fire? How could contemporaries who initiated the redevelopment of London overcome some conflicts and estrangements between their ideal for modern city and residents' realistic interests? After depicting the whole precess of the Great Fire on the basis of two contemporaries' diaries, this essay focuses on examining the above problems. Of course, the ideal of modern city that some contemporaries such as John Evelyn, Christopher Wren and Robert Hooke had sought, was deformed and distorted in the process of redevelopment of the city. Their original plans were strongly influenced by residents' interests and the city authorities' realistic necessity. For all that, a generation later, London grew as one of the most prosperous cities in Europe. Destruction is sometimes followed by new construction. The economic prosperity of London in the end of the 17 th century was helped upon its half-successful result of redevelopment after the fire.


In real-life group decision-making environment, different decision-makers (DMs) might be hesitant to provide their evaluation by more than two linguistic terms with positive, neutral, negative, and refusal information (e.g., attitude for support, neutral, oppose, and refusal) for criteria of alternative. In order to solve such kinds of decision-making problems, a novel definition of hesitant picture fuzzy linguistic sets (HPFLSs) is introduced, and the HPFLS-based methods are developed. Considering the operation laws appeared in previous papers are not well suitable for HPFLS operation, the novel operation laws of HPFLSs are developed. Then, two aggregation operators of HPFLSs are developed, including hesitant picture fuzzy linguistic weighted average operator (HPFLSWA) and hesitant picture fuzzy linguistic weighted geometric operator (HPFLSGA). Meanwhile, the related proofs are given in detail. Additionally, the comparison method of score and accuracy functions is provided to rank the alternative. Finally, a real-life case of teaching performance evaluation is used to verify the proposed methods. The same case-based comparisons are further conducted between the proposed method and previous methods. The results showed that the proposed method can well overcome the lack of operation rules appeared in previous multicriteria group decision-making (MCGDM) methods and demonstrate effectiveness.


Working with at-risk youth can be rewarding, but it can sometimes become difficult to maintain hope. This study used basic interpretive inquiry to explore and understand the experience of hope for 4 youth workers at a community organization in a large Canadian city. The authors used thematic analysis to examine data from semi-structured interviews. Three categories were constructed from the data: nourishing the hopeful self, maintaining a culture of hope, and holding hopeful perspectives. Taken in tandem with extant literature on hope, a discussion of the findings reflects on provocative ideas related to the nature of hope and the self, as well as the place of hope at work. Implications for future research and practice are explored with a focus on promoting hope for helping professionals.

The dental tissues comprising of dentin, enamel,sometimes pulp, and cementum are the hamartomas which are known as odontoma. These have behavior not so aggressive. The common type of tumor of odontogenic origin about (35-76)% is the odontoma. It is a tumor of benign type arising from epithelial and mesenchymal differentiated alteration, odontogenic cells. These odontomas are of two types–complex and compound, the both are differentiated from each other by the organization of the tissue of dental origin in a ratio of 1:2. Although the etiology is not known till now but may be related to anomalies of hereditary origin, infection,also by trauma and by hyperactivity of odontoblast process. By the means of radiological view these odontomas can be recognized and these in very few case causes expansion of the cortical bone. These odontomas occur in the second decade in number and usually takes place in the mandibular second or third molar tooth. This particular article summarizes the complex composite odontoma.


The No. 1 Ladies' Detective Agency is both a successful series of novels and a television series which ran for one series on the BBC in 2008. While the books have been criticised on a number of aspects, including its representation of Botswana, the television series has received very little academic attention at all. The television series was an international co-production between the United States, United Kingdom and South Africa, using a mix of American and South African actors in regular and recurring roles with British guest artists and production team despite being shot in Botswana. While the main features of the adaptation were primarily related to a reordering of vignettes from the books into the series, the television series added in a new character, the camp, gay hairdresser BK. At the time the series was airing, same-sex sexual activity was illegal in Botswana though that has since been changed. As such, this paper will discuss the addition of this liminal character into the series through close reading of the text and paratexts (including industrial context). Ultimately the paper will contextualise the addition with regard to both national and sexual identity and debates surrounding African queer identities.


Annual work volume of any construction company can be considered as an important indicator for the company's financial performance. Business success heavily depends on the ability of financial executives to maximize the company's net profit and annual work volume. Consequently, the firm financial managers should continuously strive to maximize their company's annual work volume. Modelling the company's annual work volume can help financial management to investigate the serious effect that the different financial conditions can have on the expected annual work volume of their companies. Stated differently, financial managers can make sure that business operations of their companies are running in a successful manner. For example, inadequate working capital may interrupt the normal operations of the business which impairs the company's annual work volume and consequently its profitability. To elaborate more, excessive levels of current assets may have a negative effect on firm's work volume and profitability whereas a low level of current assets may lead to lower level of liquidity and stock outs which results in difficulties in maintaining smooth operations that leads to a corresponding decline in the annual work volume. The objective of this research is to develop a mathematical model for the assessment of the expected construction companies' annual work volume. First, the main factors affecting firms' annual work volume were identified based on a comprehensive literature review. Next, pertinent data regarding these factors were collected. Such data are mainly concerned with the companies' financial statements as well as the economic environment. Then, two different annual work volume models were developed using the Multiple Regression (MR) and the Neural Network (NN) techniques. The validity of the proposed models was also investigated. Finally, the results of both MR and NN models were compared to investigate the predictive capabilities of the two models.


The adSp+2 × Sd−p−2 geometry of the near horizon branes is promoted to a supergeometry: the solution of the supergravity constraints for the vielbein, connection and form superfields are found. This supergeometry can be used for the construction of new superconformal theories. We also discuss the Green-Schwarz action for a type IIB string on adS5 × S5.


Aqueous solubility and stability often limit the application of aminophenoxazinones and their sulfur mimics as promising agrochemicals in a sustainable agriculture inspired by allelopathy. This paper presents a solution to the problem using host–guest complexation with cucurbiturils (CBn). Computational studies show that CB7 is the most suitably sized homologue due to its strong affinity for guest molecules and its high water solubility. Complex formation has been studied by direct titrations monitored using UV–vis spectroscopy, finding a preferential interaction with protonated aminophenoxazinone species with high binding affinities (CB7·APOH+, Ka = (1.85 ± 0.37) × 106 M–1; CB7·DiS-NH3+, Ka = (3.91 ± 0.53) × 104 M–1; and DiS-(NH3+)2, Ka= (1.27 ± 0.42) × 105 M–1). NMR characterization and stability analysis were also performed and revealed an interesting pKa modulation and stabilization by cucurbiturils (2-amino-3H-phenoxazin-3-one (APO), pKa = 2.94 ± 0.30, and CB7·APO, pKa = 4.12 ± 0.15; 2,2′-disulfanediyldianiline (DiS-NH2), pKa = 2.14 ± 0.09, and CB7·DiS-NH2, pKa = 3.26 ± 0.09), thus favoring applications in different kinds of crop soils. Kinetic studies have demonstrated the stability of the CB7·APO complex at different pH media for more than 90 min. An in vitro bioassay with etiolated wheat coleoptiles showed that the bioactivity of APO and DiS-NH2 is enhanced upon complexation.


Training activity is related to an achievement which cannot be separated from many factors and one of them is training motivation. The level of motivation possessed by the members of the Archery UKM at the University of Teknorat Indonesia has not been clearly described during the Covid-19 pandemic. With the aim of this study is to determine the level of motivation for training in Archery UKM This research is a descriptive study using the analytical survey method. The subject of this research is the Archery UKM of Technorat University of Indonesia, with a total of 15 members. The data collection technique in this study used an instrument in the form of a questionnaire. The data analysis technique used in this research is descriptive statistical analysis with proportions. The results showed that the level of motivation to exercise was 87.77%, which was divided into 53.33% intrinsic factors and 46.66% extrinsic factors. Likewise, the results of training motivation during the Covid-19 pandemic for Archery UKM Members can be classified as high.


An Ar-H2O discharge with Ar content from 0 to 95 % at 67 and 266 Pa have been studied by optical emission spectroscopy. The plasma was excited at 27 MHz by a helical cavity with a power set at 30 W. The rotational temperatures of N2(C3Πu) and OH(A2 Σ + ) emitters were determined through spectral simulations. For added Ar percentages smaller than 95 %, the rotational temperature of N2(C3Πu) state was shown to be constant and equal to the gas temperature with a value of 450 ± 50 K. The effect of energy transfer from argon metastables is probably weak considering the results on the rotational temperature of N2(C3Πu) at 95 % Ar / 5 % H2O. The experimental OH spectra could be fitted only with a two temperatures model; T1= 450 K for both pressures and T2= 15000 K with a contribution of 22 and 32 % for 266 and 67 Pa, respectively, as result of the excitation mechanisms involving electron impact collision with water.


This paper investigates methods to extract and/or characterize the scattering signature of an object in a stratified medium based on data received on a vertical array. Scattering by an object in free space transforms the incident (plane‐wave) field into a scattered field with a characteristic angular distribution. The scattering function can be estimated by correlating the scattered field with the incident field over a domain of incident and scattered angles. In an ocean waveguide, the acoustic field incident on the (submerged) object involves many multipath arrivals. Likewise, the scattered field from the object is modified by multipath propagation from the scatterer to the receiver array. Hence, extraction of the scattering function requires a method to deconvolve the channel transfer function from the received data. As the scattering function is a function of both the incident and scattered angles, a comprehensive characterization requires data covering a range of incident and scattered angles. For a d...


causes of mortality-and with, concurrently, an ageing population, the attention of the epidemiologist is likely to turn increasingly to the ills besetting the middle-aged and old. In the modern sense of the word there is, of course, no difficulty in bringing such diseases into the " epidemiological " net. When taken to comprise always the group as opposed to the individual aspects of a disease, an epidemiological picture can be drawn of every sickness to which mankind is exposed, just as a clinical picture can be drawn. In diseases of an unknown aetiology such a picture, revealing perhaps an incidence varying in space or in time, in the age of attack or in the occupations of the victims, may well provide a vital clue. The variations, for instance, in the incidence of cancer of certain sites in specific occupations-a


The aim. The aim of the research is to analyze the efficiency level of the national regulatory system in the field of medicines circulation using self-diagnostic tools, which will allow identifying reserves for its optimization and further improvement.
Materials and methods. The research materials consisted of the results of a survey conducted among government officials of national regulatory authorities in the field of medicines circulation. The research utilized methods of sociological survey, descriptive statistics, graphical analysis, data grouping, and generalization techniques. The research includes the development of a questionnaire based on the World Health Organization's "Global Benchmarking Tool" methodology, adapted to the national healthcare system. The questionnaire consisted of 2 questions to determine respondent characteristics and 104 statements about the functioning of the national regulatory system in the field of drug circulation.
Results. According to 75 % of the surveyed officials in Ukraine, an effective regulatory system operates in the field of drug circulation. Based on the number of affirmative answers, all statements were divided into 4 groups: high, sufficient, moderate, and low. Thus, the quality management system of national regulatory authorities was evaluated at a high level, while the funding system of national regulatory authorities received the lowest ratings. The grouping allowed us to identify weaknesses in the activity of the national regulatory system in the field of drug circulation, such as the lack of funds in budgets for staff training and overall insufficient funding for national regulators, including insufficient funding from international donors, lack of clarity and comprehensiveness in the regulatory framework for the pharmaceutical sector, etc.
Conclusions. In accordance with the aim of the article, we conducted research on the efficiency level of the national regulatory system in the field of drug circulation, which revealed that the most mature and effective direction of its activity today is the development and implementation of quality systems in national regulatory authorities

Real-time simulation of power electronic systems for electric ships is an essential technique for testing hardware and software in the loop. An important parameter of these simulations is the frame-time necessary to capture the dynamics of the system being simulated. Modern power electronic systems, using higher frequency pulse-width modulation (PWM) converter control, demand frame times that are significantly shorter than those found in most real-time simulators. Simulations have been developed for 6-pulse and 12-pulse, 3-phase voltage-sourced converters connected back to back and to ac systems at either end. The hardware-in-the-loop capabilities of the simulator have been tested by interfacing the simulation platform, installed on one computer, to simulated hardware on separate computers.


This investigation was designed to study the mathematical relationship between dietary fumaric acid level and the fatty acids composition of common carp (Cyprinuscarpio L.). The study was designed in 2x3 factorial experiment arrangement of two lipid levels (2%; LL and 9%; HL) and three levels of fumaric acid HO 2 CCH=CHCO 2 H (0.0, 0.5 and 1.0 %). F 0 LL, F 0 HL, F 0.5 LL, F 0.5 HL, F 1.0 LL, F 1.0 HL. The relationships between the whole body fatty acids composition and fumaric acid levels in experimental diets were evaluated by applying linear and polynomial regression analysis.ARA profile increased with elevation of dietary fumaric (R 2 =0.881) under conditions of low dietary lipid. Where a low relation were noticed for fish fed on low dietary lipid (R 2 = 0.111).weak relation recognized between dietary fumaric and DHA profile was recognized for fish fed on low dietary lipid ( R2= 0.283).On the other hand, A significant positive effect was observed (R 2 = 0.935) in the presence of high dietary lipid condition. With elevation of dietary lipid, more incubation of dietary fumaric acid up to 1% negatively affected sum of saturated fatty acid (R 2 = 0.407) and sum of mono saturated fatty acid profile (R 2 = 0.601).High inclusion of dietary fumaric in the presence of high dietary lipid encourage the improvement in DHA profile and decrease the presence of saturated and mono saturated fatty acids.


Estrogen has been known to play a critical role in regulation of male sexual behavior. Recent studies demonstrated severe impairment of male mouse sexual and aggressive behavior by targeted disruption of aromatase gene, Cyp19. In the present study, as basis for a loss of sexual behavior, we compared odor difference between wild and aromatase-knockout (ArKO) mice using probe estrous females in sexual preference paradigm. The probe fe- males reacted equally to body smell and soiled bedding of both ArKO and normal mice, suggesting androgen regu- lation of pheromones and/or attractive odorants emitted by sexually vigorous male mice. Emotionality of those mice was also measured in open field and elevated plus maze. ArKO mice had significantly low activity in open field, but not in elevated plus maze, compared to wild-type mice. We suggest that absence of aggressive behavior is based on their high emotionality (low activity in unfamiliar area).


Mulberry Silkworm, Bombyx mori L is most susceptible to different diseases caused by various infecting pathogens viz., viruses, fungi, bacteria and microsporodians. The white muscardine disease caused by a pathogen Beauveria bassiana (Balls) vuill an entomopathogenic fungi is prevalent in all the Sericulture countries of the world (Bulmer and fromtling, 1983). The cocoon production losses by this disease in different countries varies from 5-50% (Jayaramaiah et al., 1986; Jayaramaiah and kuberappa, 1987) and is among the most common diseases of silkworm in India (Krishna swami, International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 4 (2020) Journal homepage: http://www.ijcmas.com

Ever since it became possible to read Mayan dates there have been astronomical speculations about them. For those not familiar with the matter under discussion it may be stated that there are only three examples in all of texts which undoubtedly deal with astronomy: (I) the Venus Table of the Dresden Codex; (2) the Eclipse Warning Table of the Dresden Codex; (3) some 150 supplementary series attached to LC (long count)-dates dealing with the lunar age. Not even the length of the year the Mayan astronomers used is known. All this was thoroughly discussed by Teeple [1928, 1930]. More modem results, but perhaps more controversial ones, can be found in Aveni's recent books [1977, 1980]. The paper presented here was prepared to demonstrate that results which seemingly corroborate astronomical interpretations can usually be explained by mere random effects when a rigid statistical test is applied. The origin and the application of the test used is therefore discussed in detail, as well as some typical misleading probability levels resulting from 'common-sense statistics'.


The beta-gamma directional correlation of the 521-67 keV cascade in lS2Ta decay was measured to investigate the higher-order effects. The observed correlation function at / ~ = 450 keV is found to be isotropic and is given by W¢.7(O) (at / ~ 450 k e V ) = 1 + (0.025 ± ±0.031)P2(cos0 ). The A~e coefficient indicates no higher-order cont r ibutions to the 521 keV allowed but hindered beta transit ion of lS2Ta.


In the FMS of next generation, its system configuration is to be of modular type, in which the basic module is that of FMC. This FMC enables the FMS technology to be available for town and medium-size industries. To cope with such trends surrounding the FMC, it is now required of establishing a design theory of special-purpose FMC and also a standardization method of FMC. In this paper, thus, the similarity evaluation method of the FMC for metal cutting has been investigated to propose a classification method of FMC. The similarity evaluation proposed here puts its main stress on the system configuration, especially on the characteristics of the system compnent and work flow pattern, and to enable the evaluation procedure to be simplified, the FMC is represented with the directed graph. Through some trial applications, it can be verified that the proposed method is reliable and effective from the practical point of view.


This article analyzes a youth organization's struggle to start a low-watt community radio station. The project was envisioned as a way to encourage at-risk youth to become media producers and gain technical and communication skills. It was also seen as a medium through which to communicate about important social and political issues affecting the station's predominantly low-income and minority constituency—concerns not prominently covered in the commercial media. Like hundreds of US urban communities excluded from operating low power FM stations under current FCC regulations, this group initiated a 100 milliwatt AM station with hopes of eventually becoming a 100 watt FM station if FCC regulations were to change. Funding, organizational, logistical, and regulatory issues are discussed, along with obstacles and successes of this initiative and the potential for such programs to engage youth in larger issues of democracy and non-commercial expression.
