The following 15 species are new for the mycobiota in the Republic of Macedonia: Tricholoma album, T. apium, T.basirubens, T.colossum, T.columbeta, Tpopulinum, T.pseudonictitans, T.sejunctum, T.stans, T.sulphurenscens, T.tigrinum, T.ustale, T.ustaloides, T.vaccinum and T.viridifucatum. detailed distribution of Tricholoma species in the Republic of Macedonia is presented in this paper as well as their affinity for diffrent habitat types.


Salmonella's virulence genes are located chromosome and plasmid.Salmonella pathogenicity island(SPI) is a special code region related to bacteria virulence which located the chromosome of Salmonell a.Salmonella pathogenicity island 1(SPI1) contains invasion genes,which encode various components of the type Ⅲ secretion systems(T3SSs).Salmonella pathogenicity island 2(SPI2) is essential for Salmonella replication in Macrophages and Epithelial cells.Salmonella plasmid virulence genes(spv) are commonly found on plasmids contained in a small number of Salmonella serotypes which are important for the establishment of systemic infection.This review has covered recent research progress on SPI and spv virulence genes of Salmonella.


Wireless communication technologies have been studied and explored in response to the global shortage of bandwidth in the field of wireless access. Next-generation networks will be enabled by massive MIMO. Using relatively simple processing, it provides high spectral and energy efficiency by combining antennas at the receiver and transmitter. This paper discusses enabling technologies, benefits, and opportunities associated with massive MIMO, and all the fundamental challenges. Global enterprises, research institutions, and universities have focused on researching the 5G mobile communication network. Massive MIMO technologies will utilize simpler and linear algorithms for beam forming and decoding. As part of future 5G, massive MIMO technology will be used to increase the efficiency of spectrum utilization and channel capacity. The paper then summarizes the technologies that are used in massive MIMO system, including channel estimation, pre-coding, and signal detection.


Immigration is in the unconscious of the unconscious of psychoanalysis. Immigration as a dramatic instance of the always precarious social and political registers of human living. Immigration as the movement of people from one place to another, across regions and national borders and oceans, by choice or necessity. Immigration as movement across other types of social boundaries, always defining an outside and a way into a desired inside. Immigration as an inverted reflection of our deep need to belong. This paper reflects on immigration as a clinical reality and as a clinical metaphor. It uses the notion of immigration to question the perceived, often if not always illusory settledness of the analytic practice, and its tendency to privilege a sense of well-inhabited center vis-à-vis the margins we all travel through and persist in. My aim is to join Veronica Csillag in deliberating a more uncertain and daring potential for our theory making and practice.

Аt present, it can be noted without exaggeration that COVID-19 is the most serious challenge to the international system of practical health care in its recent history. Extremely high rates of morbidity and mortality dictate the need for a more detailed study of the pathogenetic aspects of the developing infectious disaster. In addition to respiratory distress syndrome, and systemic inflammatory response syndrome, COVID-19 is characterized by polyvalent disorders of the mechanisms of systemic hemostasis, which is reflected in the increase in the number of venous thromboembolic complications in the overall structure of morbidity and mortality. This literature review summarizes information on Covid-associated coagulopathy and its impact on changes in the clinical and epidemiological characteristics of venous thromboembolic complications.


No doubt every one here knows where Puerto Rico is, though I scarcely did until I was about to go there last summer. Since then I have found that others have the same wrong impression as to its location that I had. In case any one here is likewise misinformed, let me point out that Puerto Rico is about 1,750 miles due south of Nova Scotia, farther east than we often realize.


The energy thresholds of the sensory cell of the cricket wind receptor were determined to be the thermal noise level kBT (4×10-21J at 300K). The determination was based on a laser-Doppler velocimetry of the receptor hair and the Stokes' theory for viscous force. The mechanoreceptor exhibits fluctuations in spike timing to near-threshold stimuli. Simultaneous double recordings revealed independency of the fluctuations between cells. The cells employ the internal thermal noise as the seed of stochastic sampling. The thermal noise paradoxically enhances the detection of weak signal below the threshold.


The nanofiltration (NF) membrane technology has attracted considerable attention for the rejection removal of various salts. However, the practical application of this membrane separation process has been severely retarded due to the ineffective rejection of monovalent ions (such as nitrate and chloride), undesirable filtration flux, and insufficient disposal of the concentrated solution. In this work, three polyethersulfone‐type NF membranes were fabricated and their morphologies, functional groups, chemical components, wettabilities, chargeabilities, and rejection molecular weights were characterized. Among them, the membrane of NF_M3 bearing sulfonic acid group (SO3H) shows the desirable rejection efficiency of nitrate (90.32%), acceptable solution filtration flux (10.15 L m−2 h−1 at 0.6 MPa), and the decent pure water permeation flux (50.8 L m−2 h−1 at 0.6 MPa). The introduction of SO3H can significantly enhance the performances of NF_M3 membrane in hydrophilicity, chargeability, anti‐fouling, and the oxidation resistance. Promisingly, the concentrated nitrate was ingeniously recycled for the electrochemical intercalation of flake graphite to prepare expandable graphite, and the obtained expanded graphite has an acceptable expanded volume (243 mL g−1 via the microwave expansion process), thereby achieving the resource utilization of NF concentrated solution.


The purpose of this paper will be to look into the digital root of a number and the Trigg Operator and to explore any connections between the two. The Trigg Operator is the operation on the four-digit positive integer n, where n = abcd and a ≥ b ≥ c ≥ d with a 6= d defined as T (n) = badc− cdab. The digital root of a number, denoted as dr(n), is the process of repeatedly adding the digits of a number and the resulting sum, until the sum is a single digit. We will use different topics in number theory and abstract algebra to better understand the relationship between these two topics. 2 Academic Festival, Event 54 [2019] https://digitalcommons.sacredheart.edu/acadfest/2019/all/54


Buffalo recently became the latest US city to adopt a light rail package to meet its urban transport requirements. Although originally planned for half the route to be on a viaduct, objections have meant that now 80 per cent of the 10.3km line is in tunnel. Cut and cover techniques were used for the first 2.7km, but solid rock for the remainder of the line meant that the tunnel had to be bored with machines. A 1.9km section of the main street has been converted to a vehicle-free transit and pedestrian mall. There are six stations within the mall which is a fare-free zone. An integrated fare structure, allowing free transfer between bus and rail, and a self-service barrier-free collection strategy has been adopted at the stations. Unlike most US light rail lines, articulated vehicles have been rejected in favour of trains of bogie vehicles. Provisions have been made at all stations for wheelchair access to the trains. It is planned to run trains at six-minute intervals during peak periods and at 10 minutes off-peak; the line has been designed for a minimum of two minutes headway at a maximum of 88000 passengers per day. This capacity is expected to be reached as new extensions are opened, one of which is planned along an abandoned railway line. (TRRL)


Lateral diffusion of In in 20–100‐nm‐thick Au‐In films has been studied in the 60–150 °C temperature range. Indium diffusion due to the chemical potential gradient occurs from In to Au‐In with an AuIn2 phase being formed in the diffusion zone. The growth of the diffusion zone obeys a parabolic rate law with the growth rate strongly dependent on In concentration of the films. In order to understand these phenomena, the kinetics of the AuIn2 phase formation is analyzed considering In diffusion due to the chemical potential gradient with subsequent formation of AuIn2 at the diffusion front. As a result of this analysis, the diffusion coefficient of In in AuIn2 films is obtained as DIn=1.2×10−3 exp(−0.52 eV/kT) cm2/s. Grain boundary diffusion is thought to be the dominant mechanism. Additionally, a combined diffusion parameter δDg (δ is the grain boundary width) of 1.3×10−16 cm3/s (60 °C) is obtained.

Since the royals of the Northern Song Dynasty migrated to the South,the revival of the Cheng Hao and Cheng Yi's School has been a critical matter in the movement of the Neo-Confucianism in which Zheng Bo-xiong serves as an important participant.Committed to the spirit of the Confucianism elaborated by the School,Zheng Bo-xiong insists on correcting and curing the improper ideas during the period of Shaoxing.Meanwhile,he puts his propositions into practice in order to make the Confucianism pervasive and acceptable,and inherits and passes on the ideas of the School through the elaboration of the Confucian classics.His activities advance the revival of the School from Shaoxing to Chunxi,and facilitate the renewal of the declining Yongjia scholarism that he inherits.The whole Neo-Confucianism movement and regional ideas advance together by interaction.


The morphometric features a mustelide's remains found in Isma Basin near Giabal Karaza a relief more damp even in past times. It is very difficult to recognize the sub-species. These remains today look only in this area: this animal not even appears on the rock engravings of tine desert as well in great number. Up till now his land of life is clear in Northern of Jordan. The Author believes this species come from the Palestinian area or perhaps from the Dana Jordan Natural Reserve not long time ago.


and a "jobless recovery," at least as of this writing, there is a special urgency for states and communities to position themselves for the next economy, whatever it is. Every state in the U.S. is promoting its core, traditional economies, while at the same time trying to entice both perceptual and practical changes in their remaining industries. In the Midwestern areas, governors and developers are touting the next round of advanced biotechnology and agricultural value-added developments, though the value of those promotions to local investors and citizens is dubious at best. Portions of the South and the West are trying to capitalize on their evolving competitive advantages in information technologies in the face of increasing world-wide competition, not just for manufacturing jobs, but increasingly for skilled technical and communications positions. Some states are growing sharply, others are not. Some are attracting specific kinds of jobs and workers, others are bleeding jobs, people, and human capital. There is a high amount of uncertainty as to what the future will bring regarding jobs, population, and income growth for many areas of the U.S. This research explores the current emphasis on recruiting selective subsets of industries and of occupational groups. The modern parlance has been to call these creative industries and creative occupations, although the term creative arguably means different things to different groups. The first portion of this paper identifies both the creative occupational and the industrial classification territory that has recently emerged. The second, relying on basic census outcomes from 1990 and 2000 lets us profile some of the major differences among the states in their efforts to attract creative workers. The last section of this paper relies on state-level PUMS data to allow us profile the prototypical migrant in the U.S. and to classify our states as to their comparative advantages for recruiting different types of workers or workers in different types of industries.


Scottish Social Welfare, 1864-1914. By Thomas Ferguson. (Pp. 609+xi; illustrated. 42s.) Edinburgh and London: E. and S. Livingstone Ltd. 1958. This account, by Professor Ferguson, of the Scottish social welfare services is comprehensive and well documented. It is full of facts and figures supported by apt quotations. The 50 years covered show the evolution from primitive conditions to the beginnings of the Welfare State. Though the book is long, it is a pity that it stops at 1914, and it is to be hoped that a further volume, to bring it up to date, is contemplated. The early chapters describe in considerable detail the housing, earnings, diet, and general environment of the people, ranging from the slum-dwellers of the great cities to the lonely crofters and cottars of the Highlands and Islands living, along with their animals, in " black houses." Then there are over 120 pages on the relief of destitution, and all the controversies about rates of relief and whether any relief should be given to the able-bodied. This is followed by chapters with a greater medical flavour on the infectious diseases, cholera, smallpox, typhus fever, tuberculosis, and certain zoonoses; on the care of the sick, domiciliary and institutional; and on the welfare of mothers and young people. The half-century saw the beginning of the famous Highlands and Islands Medical Service, and the establishment *in 1894 of the Local Government Board, which incorporated the functions of the Board of Supervision and retained for long the latter body's Poor Law outlook with its fixed principle of discouraging idleness and imposture. It saw in 1865 the highest death rate and in 1868 the high-water mark of pauperism. The living conditions described are so degrading as to be almost unbelievable. Quotations show that Professor Matthew Hay, of Aberdeen, wrote that typhus fever was spread by body vermin. This was in 1904, and several years before the role of the louse in this disease was generally accepted. Scotland is well known for its housing problems, but it is not so well known that at the census of 1871 32.5% of the houses had only one room and that 5% of those living in them consisted of families of ten or more. The reader is brought up against the decline in the purchasing power of money when told that in 1906 the pay for unskilled labourers was 5 d. an hour, and that house rents in the country districts were about £1 to £3 a year. In a serious book such as this it is a relief to come across a lighter touch, as is the account of the formal opening by Royalty in 1903 of the Colinton Fever Hospital in Edinburgh. The guests arrived early. By inadvertence the doors of the refreshment rooms were opened too soon, and by the time the ceremony was due to start " the tables had been literally swept of all vestige of food." The book deals not only with purely medical matters, but also with those, now comprised in the term "social medicine," which lead to, or are at least associated with, ill-health. It can be highly recommended, and there is a full bibliography for those who wish to gain even further information. ALLEN DALEY.


BACKGROUND
As warm ischaemic damage is a major reason for the loss of donor organs, an experimental study was performed in order to evaluate retrograde oxygen persufflation (ROP) as a method to extend the warm ischaemic tolerance of kidneys.

METHODS
Kidneys of 32 pigs were exposed to warm ischaemia for 60, 90 or 120 min. Then, 16 kidneys were subjected to ROP for 4 h at 4 degrees C and 16 controls were stored in cold UW-solution, followed by autotransplantation.

RESULTS
Only in the group with 60 min warm ischaemic time and ROP did all animals survive the observation period of 7 days. In all other groups some animals died due to anuria. Short-term survivors in these groups had significantly higher creatinine levels.

CONCLUSIONS
In this setting, ROP was superior to cold storage when applied after 60 min of warm ischaemia. Clinical evaluation of ROP in the setting of marginal donors and non-heartbeating donation is recommended.

Cornelia Sorabji appeals to the Vice-Chancellor of Oxford University when"the London Examiner for the B.C.L. Examination refuses to examine a woman"(P-29 India Calling -1934) and succeeds in reversing the decision. In their effort to acquire knowledge and economic independence, many women of the late nineteenth and the early twentieth century India struggled against the universal phenomenon of gender discrimination and in the process broke into the exclusively male professional domains such as law, acting, medicine, politics etc. The nineteenth century was a period of social reform when issues such as Sati, child marriage and widow remarriage –issues related to women and human rights—were greatly debated upon. Strange was the fact that women themselves were not allowedto articulate their needs or opinions. Stranger was the fact that most of these women writers hardly exhibited any interest in the questions raised by the social reformers. Asignificant number of women felt indignant at this marginalization of female capabilityand with a growing sense of social injustice and unreasonable patriarchal domination these women started expressing through their writings. Their choice of the genre of autobiography to question the gender differences is significant in that it is proof of the realization of women of their self-worth and the potential of this genre to reflect the social conditions beyond an individual's control and beyond the text.
 The texts to be studied are India Calling:The Memories of Cornelia Sorabji (1934) and A Look Before And After (1956), the autobiography of Shoilabala Das. This paper proposes to study how the autobiographies of Cornelia Sorabji—India's first woman barrister—and Shoilabala Das-- India's first Honorary Magistrate—present a critique of the existing social conditions and their efforts to access knowledge and resources with a desire for recognition andor upward social mobility.The objective of this study is to reveal how by adopting unconventional professions they face problems and how they try to overcome these problems through their skills thus giving themselves a new identity and atthe same time how they work for the economic, social, educational and political emancipation of Indian women.


SUMMARY
The wild-type parental strain and a het+nif− mutant of Nostoc linckia grow heterotrophically in light, with and without DCMU, and in darkness when supplemented with a source of carbon. Glucose and sucrose stimulated heterocyst production. Glucose enhanced the uptake of ammoniacal nitrogen from the medium when parent and mutant were grown in an ammonium-supplemented medium. Effects of cAMP (sodium salt and dibutyryl), with and without glucose, on growth and heterocyst differentiation of parent and mutant were studied. Dibutyryl cAMP, in general, was found to be toxic to the alga, but the sodium salt of cAMP enhanced growth with glucose. The mutant grew well in a nitrogen-free medium supplemented with cAMP.


A Pb-Zn-Ag deposit located at Tanjung Balit, Limapuluh Kota Regency, West Sumatra, is hosted within the meta sedimentary rocks of the Tapanuli Group. The lithology consists of interbedded shale, meta sandstone, slate and phyllite (Kuantan Formation). The deposit is in the form of veins, veinlets and disseminated. The thickness of veins ranges from few centimeters up to 5 meters.  In places, some ore bodies are conformable with the host rocks. The main ores are lead, sphalerite, chalcopyrite, pyrite and silver with minor marcasite, magnetite, chalcosite and gold. Hydrothermal mineral assemblages consist of silica, illite, monmorillonite, pyrophyllite, muscovite, siderite, diaspore, dickite, magnesite, chlorite, carbonate, rhodochrosite, analcime, alunite, smectite, ankerite, calcite, dolomite, sericite and zeolite. Fluid inclusion measurements of secondary inclusions within quartz veins indicate that the homogenization temperature (Th) ranges from 185 - 350oC. The presence of alunite, higher content of base metals as well as higher temperature range of the secondary fluids suggests that the deposit may characterize a high suphidation epithermal type. Keywords : Tanjung Balit, Tapanuli Group, fluid inclusion,  high sulphidation epithermal


We studied the G\ensuremath{\gamma}=2 imperfection depolarizing resonance at 108 MeV, both with and without a Siberian snake, by varying the resonance strength while storing beams of 104- and 120-MeV polarized protons at the Indiana University Cooler Ring. We used a cylindrically symmetric polarimeter to simultaneously study the effect of a depolarizing resonance on both the vertical and radial components of the polarization. AT 104 MeV we found that the Siberian snake eliminated the effect of the nearby G\ensuremath{\gamma}=2 depolarizing resonance.


The effect of ambient relative humidity (70 and 90%, RH) and temperature and a 70 and 90% RH and temperatures (25, 30 and 35C) on microbial spoilage of whey protein concentrate (WPC34) and whey protein concentrate (WPC80) stored for up to 18 months were investigated. WPC34 and 80 were packaged in bags marked as standard (Std) and high performance (HP), and every 3 months changes in the behavior of aerobic mesophilic bacteria, yeast and mold and lipolytic bacteria were monitored. Initial populations of aerobic mesophilic bacteria in WPC80 and WPC34 averaged 2.7 and 1.6 log CFU/g, respectively. Yeast and mold populations of WPC34 in HP bags increased slightly during storage at 30 and 35C in a 70 and 90% RH, respectively, while lipolytic associated bacteria were not determined in the same samples. The pH of samples in all bags declined while water activity (aw) slightly increased during storage especially at higher RH and temperatures.

Pratical Applications

Information on the effect of adverse long-term storage conditions on whey protein concentrate (WPC) is needed for effective supply of this product to Africa and other semi-arid regions. This study investigated differences between ambient relative humidity storage, temperatures and type of bags on native microbial population, water activity and pH of WPC. It also, provides WPC manufacturers a better insight with regards to storage conditions and type of bags that can maintain longer shelf life. The data from this study could be used for quality control purposes and or development of a better bag suited for storage above ambient conditions.


Corona virus infection is a worldwide health threat that has infected a substantial portion of the world's population and is caused by SARS-CoV-2. It is the natural tendency of a virus to change the genetic makeup through point mutation, and such viruses are called variant of the original virus. The SARS-CoV-2 virus also undergoes such mutation (maybe one or more and distinct from other) over time and many genetically diverse variant has risen. Such variants might be variants of concern (VOC) and variants of interest (VOI) based on the differences in virulence, transmissibility, pathogenicity, and vaccination efficacy. Omicron, a new VOC of SARS-CoV-2, has recently emerged as global distress to more than 115 countries. The article provides a summary of the evolutionary, biological, and genomic aspects of different SARS-CoV-2 VOC with respect to Omicron and found that amino acid mutation in spike proteins such as A67V, ∆69-70, Q954H, N969K, L981F etc and other structural protein mutations such as D3G, Q19E, A63T in membrane protein, T9I in envelope protein and P13L, ∆31-33, R203K, G204R in nucleocapsid protein results major differences between different VOC/VOI of SARS-CoV-2. Further, the effectiveness of the widely used SARS-CoV-2 vaccines has been reviewed specific to Omicron. The existing available Covid-19 vaccines developed and manufactured by Pfizer, AstraZeneca, Johnson & Johnson, Moderna, and Novavax show reduced efficacy against the latest VOC of SARS-CoV-2 Omicron. Based on the available literature of preliminary findings, people who get a booster shot or a third vaccine dosage may have better protected against Omicron.


In this study, we present a facile method to construct highly ordered and well-defined ionic channels in anion-exchange membranes (AEMs) through in-phase photopolymerization of liquid crystals (LCs). Hexagonal and lamellar LC samples were prepared by the self-organization of polymerizable amphiphilic imidazolium-based ionic liquids. The preservation of LC nanostructures in the obtained polymeric membranes was confirmed by the combination of small-angle X-ray scattering (SAXS), polarized optical microscope (POM), and scanning electronic microscopy (SEM) measurements. Phase separations of LCs at the molecular level provided highly ordered and well-defined ionic channels for efficient anion conduction and meanwhile maintained a strong hydrophobic domain to suppress the swelling degree. The membranes synthesized in the present work provide a promising model system for understanding the idea of constructing ionic highways in AEMs through self-organization.


The reaction pi N -> pi pi N is studied at tree level up to next-to-leading order in the framework of manifestly covariant baryon chiral perturbation theory with explicit Delta(1232) degrees of freedom. Using total cross section data to determine the relevant low-energy constants, predictions are made for various differential as well as total cross sections at higher energies. A detailed comparison of results based on the heavy-baryon and relativistic formulations of chiral perturbation theory with and without explicit Delta degrees of freedom is given.


In this article, we propose video delivery schemes insuring around 1s delivery latency with Dynamic Adaptive Streaming over HTTP (DASH), which is a standard version of HTTP Live Streaming (HLS), so as to benefit from the video representation switching between successive video segments. We also propose HTTP/2-based algorithms to apply video frame discarding policies inside a video segment when a selected DASH representation does not match with the available network resources. The current solutions with small buffer suffer from rebuffering events. Rebuffering not only impacts the Quality of Experience (QoE) but also increases the delivery delay between the displayed and the original video streams. In this work, we completely eliminate rebuffering events by developing optimal and practical video frame discarding algorithms to meet the 1s latency constraint. In all our algorithms, we request the video frames individually through HTTP/2 multiple streams, and we selectively drop the least meaningful video frames thanks to HTTP/2 stream resetting feature. Our simulations show that the proposed algorithms eliminate rebuffering while insuring an acceptable video quality with at least a Peak Signal to Noise Ratio (PSNR) of 35dB compared to 25dB of the basic First In First Out (FIFO) algorithm. We also quantify and qualify the resulting temporal distortion of the video segments per algorithm. An important number of missing video frames results in a temporal fluidity break known as video jitter. The displayed video looks like a series of snapshots. We show that both the optimal Integer Linear Program (ILP) and practical algorithms decrease the frequency and duration of the jitters. For example, practical algorithms reduce the number of crashed displayed videos (presenting one jitter longer than 1,350ms) with 22% compared to the basic FIFO algorithm. We also show that requesting video frames separately with HTTP/2 slightly increases the overhead from 4.34% to 5.76%.


SUMMARY Introduction: it has been shown that the prosthe- sis - patient mismatch (PPM) is associated with persisting pulmonary hypertension after mitral valve replacement (MVR). Because of the this, the objective of the present study is evaluate the im- pact of PPM on mortality in patients undergoing MVR. Methods and results: the indexed valve effective orifice area was estimated for each type and size of prosthesis being implanted in 114 patients and used to define PPM as not clinically significant if > 1,2 cm²/m², as moderate if > 0,9 and 1,2 cm²/m², and as severe if 0,9 cm²/m². Moderate PPM was present in 34%; severe PPM was seen in 10%. For patients with severe PPM, there was not surgical mortality, 8% in patients with moderate PPM and 6% in those with PPM not clinically significant. For patients with severe PPM, mortality in the follow up (45%, CI95% 18-75%) is greater than those with moderate PPM (11%, CI95% 4-27%) and signifi- cantly greater than those with not clinically signi- ficant (2%, CI95% 0,08-10% p<0,05). On multiva- riate analysis, severe PPM is associated with hig- her mortality (odd ratio, 3,22; CI 95%, 1,08 a 36). Conclusions: severe PPM is an independent pre- dictor of mortality after MVR. For patients identi- fied as being at risk for severe PPM, every effort should be made to implant a prosthesis with a lar- ger effective orifice area.


Abstract Mechanically alloyed aluminium powder has been consolidated by a single cycle of cold pressing and sintering to produce bulk powder metallurgy (PM) aluminium parts. To facilitate the difficult consolidation, the as milled aluminium powder, eventually in the annealed condition, was mixed, previously to pressing, with a small amount of magnesium powder, as sintering aid. Both the blending of magnesium powder and the annealing treatment improves ductility and strength of consolidated samples simultaneously. Bulk samples also have a remarkable stability and performance at high temperature.


Objective To compare the clinical significances of different imaging examinations for diagnosis of pulmonary embolism(PE). Methods Sixty three patients suspected to PE were examined respectively by different imaging examination such as chest X-ray, cardiac ultrasonograph, CTPA, and pulmonary V/P scintigraphy, some of which were also examined with MRPA and PGA. Clinical significances of different imaging examinations for PE diagnosis were evaluated. Results The sensitivity of chest X-ray, cardiac ultrasonograph, pulmonary V/P scintigraphy and CTPA, as well as MRPA and PGA were 43.48%, 54.35%, 95.65%, 95.45%, 87.10% and 97.50%, respectively. While the specificity of them were 35.29%, 76.47%, 94.12%, 93.75%, 92.31% and 100.00%, respectively. The sensitivity and specificity had no significant difference between pulmonary V/P scintigraphy, CTPA and PGA(χ2=2.13, 3.36,P0.05). The sensitivity and specificity had significant difference between chest X-ray, cardiac ultrasonograph, and PGA(χ2=19.87, 26.73, P0.05). Conclusion Chest X-ray and cardiac ultrasonograph can only be used as a screening examination. It is considered to replace PGA with pulmonary V/P scintigraphy and CTPA, or MRPA.


The world is going through a difficult time with the COVID-19 pandemic for the last five months and has affected more than 200 countries. Wuhan in China was the first place and then this has spread all over the globe. The virus affects the respiratory tract predominantly leading to death more so in the elderly and those with comorbid conditions. All routine and planned surgical services had to be stopped in view of the very rapid spread of the virus compounded by the lack of a proper treatment. It has been nearly 90 days and surgical services need to restart. There are various protocols being practiced and we have also put up a protocol which is simple and wherein the disease has been triaged into three groups and accordingly treatment is executed. All surgical emergencies are treated considering them as COVID positive till proved by a negative test.


Enzymes conjugated to magnetic nanoparticles (MNPs) undergo changes in the catalytic activity of the non-heating low-frequency magnetic field (LFMF). We apply in silico simulations by molecular dynamics (MD) and in vitro spectroscopic analysis of the enzyme kinetics and secondary structure to study α-chymotrypsin (CT) conjugated to gold-coated iron oxide MNPs. The latter are functionalized by either carboxylic or amino group moieties to vary the points of enzyme attachment. The MD simulation suggests that application of the stretching force to the CT globule by its amino or carboxylic groups causes shrinkage of the substrate-binding site but little if any changes in the catalytic triad. Consistent with this, in CT conjugated to MNPs by either amino or carboxylic groups, LFMF alters the Michaelis–Menten constant but not the apparent catalytic constant kcat (= Vmax/[E]o). Irrespective of the point of conjugation to MNPs, the CT secondary structure was affected with nearly complete loss of α-helices and increase in the random structures in LFMF, as shown by attenuated total reflection Fourier transformed infrared spectroscopy. Both the catalytic activity and the protein structure of MNP-CT conjugates restored 3 h after the field exposure. We believe that such remotely actuated systems can find applications in advanced manufacturing, nanomedicine, and other areas.


Market relations in the agricultural sector require enterprises to have a profound understanding and efficient management of expenses. The relevance of the topic is determined by the need for making prompt financially justified decisions in the field of marketing based on accounting data about the composition, structure, and dynamics of expenses of agricultural enterprises. The purpose of the study is to improve the classification of marketing activity costs of agricultural enterprises, aimed at enhancing the efficiency of enterprise resource utilization, optimizing marketing activity expenses, and ensuring the sustainable development of agricultural enterprises. To achieve the stated goal, the following methods were used in the research: analysis, analogy, and generalization – to study scientific works on the topic of the article; observation and detailed description helped to gather and summarize factual material. Assessing the level of marketing expenses will allow for the budgeting of marketing measures, including expenses for advertising, product promotion, market research, and other marketing activities. Accounting for marketing activity expenses will help the enterprise determine how significant its marketing investments are and whether they meet the set objectives. The structure of marketing expenses indicates the distribution of funds among various marketing channels and tools. This allows determining which marketing means are more efficient and result-oriented. The research summarizes the views of scientists on the essence and structure of marketing activity expenses of agricultural enterprises, analyzes the possibilities of using the mentioned classifications for the accounting representation of marketing expenses. Based on this, an updated classification of marketing expenses was proposed, which emphasizes digital marketing as a separate group, considering the technological direction of business processes development. This segment includes expenses for paid search results in search engines, product promotion on specialized agricultural electronic resources, social media marketing, and collaboration with influencers. The implementation of the mentioned classification will allow to optimize marketing expenses, expenses, strengthen competitive positions and productivity of the agrarian business. It can also be used for further research on marketing activity accounting and management in agricultural enterprises.


All must be sorted. Records, photos, files— a billion treasures for the ultimate hoarder's shrine—flow every second from Headquarters out to a hall of servers in the West. In Utah. Where else? Somehow it makes sense: the alien landscape, hidden veins of ore, gold tablets of encoded Mormon lore— it's all connected. Deep in Utah, miles from any town, walled off from any seeker, a server holds me in its gleaming pod. It sees my mind as clear as God sees God. Into that hall my life will be compressed


This paper describes a new method for optimizing traffic signal offsets to reduce the travel time and the number of stops while enhancing safety by imposing constraints not to divide platoons. Conventional traffic signal offset is determined by a time consuming iteration of manual setting and through field examination. However, the authors' method tries to model the traffic situation of the target network by adjusting the model parameters such as the time headway and the link velocity in order to minimize the error between the traffic trajectories within the model and the trajectories actually acquired by probe cars equipped with global positioning system (GPS) receivers. Given the cycle time and split of each intersection, the authors' method searches for the best offset by using a genetic algorithm together with the steepest descent algorithm in which a number of simulations are run and compared. This method gives the near optimum solution, which is not affected by initial settings of the offset, within a reasonable time. The results of the computer simulations for several arterial roads which experience heavy traffic congestion show a superiority of their new method over conventional fixed parameter signal controls. Unlike the conventional programs, their method is suited to congested cases. The average travel time decreased by 12% - 24% on an arterial road length with 13 intersections. The number of stops decreased by about 40%. This was achieved by automatically suppressing shock waves of vehicles by suitably placing red intervals.

Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its structure. Often the technique gets overlooked as designing and implementing a model on a scale large enough to be worthwhile can be both time consuming and require specialist programming skills. Currently there are a few notable efforts to produce homogenised software to allow researchers to quickly design and run DEMs with in excess of 1 million elements. However, these applications, while open source, are still complex in nature and require significant input from their original publishers in order for them to include new features as a researcher needs them. Recently software libraries notably from the computer gaming and graphics industries, known as physics engines, have emerged. These are designed specifically to calculate the physical movement and interaction of a system of independent rigid bodies. They provide conceptual equivalents of real world constructions with which an approximation of a realistic scenario can be quickly built. This paper presents a method to utilise the most notable of these engines, NVIDIAs PhysX, to produce a parallelised geological DEM capable of supporting in excess of a million elements.


Extraction of conjugated linoleic acid glyceride by supercritical carbon dioxide was investigated in the paper.The influences of extraction temperature gradient and pressure on extraction process were discussed.The experimental results showed that the seperation rate was relatively high but the extraction efficiency was relatively low without the temperature gradient,and the least acid value of the fraction was 3.94 and the highest content of diglyceride was 67.08% with the temperature gradient of 10℃ and pressure scope of 12.75~16 MPa.Under the optimized conditions,the fraction obtained by supercritical carbon dioxide extraction was almost colorless.


It is proposed to consider the process of carbon materials oxidative activation from the positions of topochemical reactions involving chemisorption of the activating agent (oxidizer) on the material surface active centers followed by chemical interaction. Such an approach makes it possible to control the process of creating a carbon material with the desired characteristics of the porous space. It is assumed that the oxidizer chemisorption active centers are amorphous carbon, which is localized on the material crystallites boundaries. The change in the length of these boundaries will lead to a change in the process rate. It is shown that the number of such active centers on the carbon material surface depends on the size of the crystallites. It will have a significant impact not only on the rate of activation, but also on the possibility of the process flow on the surface or with porosity formation. Mathematical models describing the carbon sample specific surface changing in the oxidation process are proposed. They allow quantifying the proportion of carbon that is oxidized on the sample surface or with pores formation, as well as quantifying the number of pores. It is shown that the ratio of pore formation and surface oxidation processes depends on the oxidation temperature, the oxidizer nature and its flow rate. The proportion of porosity formation decreases with the increase in the oxidant flow rate and the increase in temperature. It was experimentally shown that in order to obtain a material with a more developed porous space and a high specific surface it is preferable to use carbon dioxide as an oxidizing agent.


Growing global competition has virtually eliminated assured markets and has forced manufacturers in nearly all sectors to find a new production model, one of which is known as agile manufacturing. It includes different aspects which workforce agility has been asserted as a vitally important contribution to agile manufacturing. Despite the importance of workforce agility, little focus has been given to it. The shortage of study in this matter has affected the behaviour of enterprises. This study reviews studies on workforce agility and finally an algorithm is suggested which can help managers to have agile people.


In this paper, a compact triple band-notched Ultra Wideband (UWB) antenna with sharp band-elimination features and controlled notched bandwidths is proposed and discussed. The design is made up of a rectangular-shaped   patch UWB planar monopole antenna with double collections of band-notched configurations. The band-notched configurations are involved to produce the desired lower and upper stop bands with good frequency selectivity and suitable stop bandwidths. The first notch is realized by using a C-shaped slot etched in the radiating patch in order to eliminate the interference at the WiMAX (3.4 - 3.8 GHz) applications. The second and the third notches are realized together by using a pair of U-shaped resonators that are located beside the feed line in both sides to eliminate the interference with the lower WLAN (5.15–5.35 GHz) and the higher WLAN (5.725–5.825GHz) bands.  Additionally, the bandwidths of the lower and upper stop bands can be control separately by changing the parameters of the band-notched configurations. Furthermore, the suggested triple notched bands UWB antenna is optimized, fabricated, and measured for verification purposes. The measured results are close to the simulated ones.


This article intends to review the Argus' simile function (Prop. I 3,19-20) in its relationship with the two figures of elegiac discourse, lover and beloved, taking into account the play between similar and dissimilar elements. From beholding to being seen two ways of behaving are written.


Paper discusses theoretical approaches to the sociological analysis of public risk perceptions an d attitudes to the siting of nuclear waste facilities . Nuclear power, being a very controversial social, economic, technical and environmental issue in itse lf, manifests one particular type of social risks, name ly the long-term implications of radioactive waste storage . The article discusses the possible interpretations of negative public attitudes towards nuclear waste, al so theoretical assumptions of social constructionism a nd cultural theory about social risk perception in gen eral and nuclear waste disposal perception in particular . The dominant syndromes of NIMBY and NIABY reflected in public perception are discussed pointi ng to the social unacceptability of nuclear waste siting in different neighborhoods of industrialized affluent countries. Looking for the analytical model to expl ore social controversies over nuclear power-related ris ks in the case of Lithuania, the notion of discourse coal itions is deployed. This concept, paper concludes, is rele vant as a methodological approach in order to identify t he contents of debate on nuclear power and waste sitin g as well as key-actors and their social constellations ‐ scientists, politicians and the lay public ‐ shapin g the public discourse. The complexity of transition from 'simple' modernity to a 'double risk-society', the paper concludes, is even of greater importance in shaping social attitudes and value-orientations as compared to social-demographic variables of individuals and communities as well as general manifestations on NIMBY.


Dream content analysis is one of the basic methods applied in psychological dream research. The method can be easily applied but several pitfalls must be avoided in order to get valid results. The present article outlines how to construct new scales and the problems related to reliability and validity of content analytic scales. In addition, statistical issues prominent in the analysis of dream content data are addressed. Despite the various efforts and published findings in dream research, the systematic study of the advantages and problems of the dream content analysis method is still at the beginning.

Results of recent lipid lowering trials ( Table 1 ) where new (dalcetrapib) and established agents (niacin) were tested on a background of statin therapy have been disappointingly negative. This outcome has been the cause of much consternation for those developing new lipid regulating drugs, and prompted reflection among experts on long-cherished concepts and the practical implications of continued dependence on statin monotherapy in prevention strategies. Key current issues are summarized in the following questions: (i) Why are statins so effective and what should we do to increase their impact? (ii) What can we expect realistically from additional or add-on lipid lowering? (iii) What does the future hold?

### Statins are highly effective at lowering atherogenic lipoproteins

Classical epidemiology, genetic (Mendelian randomization) studies, investigations of atherosclerotic plaque formation, and intervention trials place beyond doubt the role of low-density lipoproteins (LDLs) as a causative agent in coronary artery disease. Statins, depending on potency and dose, reduce LDL levels [measured as LDL-cholesterol (LDL-C)] by 20–50%. They also decrease plasma concentrations of other apolipoprotein B-containing particles believed to contribute to plaque formation, and it is this ability to lower the circulating levels of all atherogenic lipoproteins that may underpin the benefits seen in a wide range of patient phenotypes.1,2

Statin therapy gives rise to an early-risk reduction that is evident within 12 months of initiating treatment, and persists over many years. For example, in the long-term follow-up of the West of Scotland Coronary Prevention Study, those allocated to placebo had a cumulative risk of 12% for incident coronary heart disease (CHD) at 10 years (5 years after the formal trial ended); those given a statin did …


Heart Rate Variability (HRV) is a physical phenomenon where the time interval between heart beats varies. It is measured by the variation in the beat to beat interval. Abnormalities present in the time interval between R wave peaks in the Electro-cardiogram (ECG) indicate cardiac dysfunction. Autonomic Nervous System controls the cardiac activity of the body and provides the beat to beat regulation of the cardiovascular system. Thus Heart Rate Variability is an important tool to access autonomic function also. The source for HRV is a continuous beat to beat measurement of interbeat intervals. An ECG signal can be used as the data source for HRV analysis. In this study the HRV data is obtained from ECG signal and is processed to calculate spectral HRV index, LF/HF ratio. Keywords-Ectopic beat; Heart rate variability, Wavelet Transform, Detrending, Myocardial infarction.


Background: Unintended pregnancy is an important public health issue in both developing and developed countries because of its negative association with the social and health outcomes for both mothers and new-born. Aim: The aim of this study is to explore the determinants of unintended pregnancy and estimate its risk of developing adverse pregnancy outcomes. Subject and Methods: A correlational study was conducted at Helwan general hospital (from September 2010 to February 2011) on 253 pregnant women at third trimester. Of them 82 women had unintended pregnancy, and 171 women had intended pregnancy. Data were collected by using a structured interview questionnaire to collect data about sociodemographic characteristics, pregnancy intention status as well as complains associated with pregnancy. At time of delivery, weeks of gestation and mode of delivery were recorded. After birth, the newborns were assessed for birth weight and if they had any neonatal complication. Results: Nearly one-third (32.4%) of study sample had unintended pregnancy with mean age of 29.89 + 4.20 years compared to 26.51+ 4.8 years for intended. Comparing with intended pregnancies group, they had low educational and economical levels, and they had high parity and previous unintended pregnancies (P<0.05, P<0.001, P<0.0001, and P<0.0001, respectively). In addition, they had increased risk to develop gestational diabetes, hypertension during pregnancy, and to be hospitalized during pregnancy. (AOR.= 4.26, 4.19, 2.67 respectively). Their infants had increased risk to have low birth weight and to admit to Intensive Care Unite (OR= 3.03 and 2.33 respectively, P= <0.05), but these associations were no longer significant when the mother's socioeconomic status and their receiving to antenatal care are also taken into account (AOR=1.76 and 1.64 respectively).Conclusion and Recommendation: Previous unintended pregnancies, increasing age and high fertility, in addition to lowering educational and economical level were determinants of unintended pregnancy. Women with unintended pregnancies were more likely to develop some adverse pregnancy outcomes than women with intended pregnancy. Exploring the causes of unintended pregnancies and developing strategy to reduce its occurrence is recommended to improve the maternal and newborn health.

Methods and devices are disclosed for the non-invasive treat ment of neurodegenerative diseases through delivery of energy to target nervous tissue, particularly the vagus nerve. The devices include a magnetic stimulator having coils with toroidal windings, which are in contact with an electrically conducting medium that is adapted to conform to the contour of a target body Surface of a patient. The coils induce an electric current and/or an electric field within the patient, thereby stimulating nerve fibers within the patient. The stimu lation brings about reduction of neuroinflammation in patients suffering from conditions comprising Alzheimer's Disease, Parkinson's Disease, Multiple Sclerosis, postopera tive cognitive dysfunction and postoperative delirium. Reduction in inflammation is effected by enhancing the anti inflammatory competence of cytokines such as TGF-beta, wherein a retinoid or components of the retinoic acid signal ing system provide an anti-inflammatory bias, by enhancing anti-inflammatory activity of a neurotrophic factor Such as NGF, GDNF, BDNF, or MANF, and/or by inhibiting the activity of pro-inflammatory cytokines such as TNF-alpha.

Abstract Sydnone methides are described from which only one single example has been mentioned in the literature so far. Their deprotonation gave anions which can be formulated as π‐electron rich anionic N‐heterocyclic carbenes. Sulfur and selenium adducts were stabilized as their methyl ethers, and mercury, gold as well as rhodium complexes of the sydnone methide carbenes were prepared. Sydnone methide anions also undergo C−C coupling reactions with 1‐fluoro‐4‐iodobenzene under Pd(PPh3)4 and CuBr catalysis. 77Se NMR resonance frequencies and 1 J C4‐Se as well as 1 J C4‐H coupling constants have been determined to gain knowledge about the electronic properties of the anionic N‐heterocyclic carbenes. The carbene carbon atom of the sydnone methide anion 3 j resonates at δ=155.2 ppm in 13C NMR spectroscopy at −40 °C which is extremely shifted upfield in comparison to classical N‐heterocyclic carbenes.


Over the past four decades, Accra has witnessed an increasing influx of young women who migrate to the city with the sole aim of carrying goods. This paper examines the migration processes of these young women, who mostly migrate from the northern part of Ghana to Accra, in the South. A sample of 216 female porters were selected for the study. A survey, personal interviews, and focus group discussions were the main tools for data collection. The reasons for their migration, the parties involved in the decision to migrate, and how their migration was financed were explored. The study revealed that the migration process of female porters is enabled by social networks; the women have varying levels of social capital, which facilitates movement and settlement. These social networks increase the social asset base of female porters and provide safety nets for them. It is found that the reasons for their migration are related to the declining importance of agriculture and the non-availability of jobs at their origin, which can be blamed on the liberalisation of the Ghanaian economy. It is also found that mothers are deeply involved in their daughters' migration decisions.


Optimization of linear time-invariant systems, using a given time-weighted quadratic performance index, is investigated for the prespecified closed-loop eigenvalues. The necessary conditions have simple forms and this algorithm gives a considerable amount of computational time savings compared to the previous algorithms [1]-[2].


Heat exchanger tube rolling introduces tensile residual stresses in the expanded part of the tube and the transition zone between the expanded and unexpanded regions of the tube. These tensile residual stresses accelerate fatigue crack initiation and enhance small crack propagation and may cause stress corrosion cracking of the tube if it is exposed to a corrosive environment. In this paper, an axisymmetric finite element model has been used to evaluate the effect of large initial tube-tubesheet radial clearance and to evaluate the effects of grooves machined in the tubesheet hole on the distributions and magnitudes of the radial deformation of tube walls and the residual stresses along the expanded length of the tube and in the transition zone. The results have revealed the presence of tensile and compressive residual axial and hoop stresses in the inner and outer surfaces of the tubes with various degrees of severity.


A solar cell device and a method of fabricating the device are described. The solar cell is fabricated by providing a substrate, depositing a back contact over the substrate, depositing an absorber over the back contact, depositing a front contact over the absorber, and embedding a highly thermally conductive material within the solar cell. The highly thermally conductive material can be embedded as a highly thermally conductive layer between the substrate and the back contact, a highly thermally conductive fill within a P3 scribe line, or both.


The mathematical model and results of theoretical investigations of forming voltage and current pulses in the high power microwave generator - virtual cathode triode are presented. The power supply circuit incorporates an energy storage with an electro-explosive opening switch. The more cor- rect EEOS resistance dependence and current- voltage characteristic are contained in the model. It is possible to simulate forming voltage and cur- rent pulses in the high power of the high power microwave generator when using explosion-mag- netic generator as the power supply on the base of this model.


God, Jews and the Media: Religion and Israel's Media, by Yoel Cohen, Routledge Jewish Studies Series, 2012. 258 pp.Reviewed by Haim ShapiroSeveral years ago, Bar flan University held a symposium on religion and the media. As a newspaper reporter, I was curious as to what the panelists might have to say about the moral issues occasionally faced by journalists. For example, what did the Jewish sages have to say about the conflict between the public s right to know and the prohibition of lashon hara (gossip) ? How does one deal with the possibility of ruining someone's reputation or even endangering his or her life by reporting on something that was said or done ? I wondered if any of the journalists on the panel, some of them religiously observant, had ever consulted a rabbi on such issues.To my disappointment, the symposium quickly evolved into a discussion on the way in which the media portrays the Jewish settlers in the disputed territories, most of whom are identified with the national-religious movement. I then realized that this was what interested most of the audience, which clearly sided with the settlers.Yoel Cohen, a professor in the School of Communications at Ariel University, has delved into a vast array of issues relating to Jewish religious practice and the media, surveying not only the written press, radio, and television, but also internet coverage and the leaflets distributed on a weekly basis to worshippers at synagogues. He has surveyed the range of Israel's Jewish population: the Haredi (ultra-Orthodox) Hassidic and Lithuanian yeshiva circles, the modern Orthodox, the traditional and secular communities, and even the demographically small Conservative and Reform movements. Indeed, Cohen's study reveals that media coverage of "religion" in Israel is concerned, most often, with specific groups and the way they relate to one another. That is, theology per se is not considered particularly newsworthy.Considerable media attention, Cohen notes, is paid to the members of the Haredi community, both because they are picturesque, with their distinctive dress and lifestyle, and because of their political clout. When Shas, a Sephardic Haredi party, was organized to challenge the Ashkenazi Agudat Yisrael, which had hitherto claimed the entire Haredi vote, there was additional coverage. Later, when yet another Haredi party, Degel Hatorah, associated largely with the rationahst Lithuanian yeshivot came on the scene, there was even more material for journalists. Cohen reminds us of an interesting paradox: The rabbis who guided each of these political parties and were themselves a source of media interest remained almost entirely inaccessible to the press. The former Sephardic chief rabbi and spiritual mentor of Shas, Rabbi Ovadya Yosef, is an excellent example. In the absence of direct access, journalists would regularly cover his weekly Saturday night sermons, broadcast by satellite, and report on his more outrageous remarks.Another colorful figure, whom Cohen does not mention, was the late Rabbi Eliezer Schach, the aged mentor of Degel Hato rah, whose pronouncements were top news. In a 1990 Tel Aviv rally, he held the fate of the government in his hands while masses of black-garbed followers contrasted sharply with a small cluster of journalists who relied on an interpreter to translate Schachs Yiddish into Hebrew. And, while Cohen does to some degree discuss Habad, a more developed treatment of this movement s relations with the media would have been welcome.At the other end of the religious spectrum, one would have also hoped for an in-depth analysis of the role of Rabbi Uri Regev who, as head of the Reform Movement s Israel Religious Action Center, ran a well-oiled campaign on two fronts, in the courts and in the media, relating to a series of issues challenging the Orthodox hegemony over Israels religious life. Regev succeeded in doing this in spite of the fact that most Israeli journalists, even those covering the "religious" beat, knew even less about Reform Judaism than they did about the Haredim. …


The present paper addresses the question of the nature of deception language. Specifically, the main aim of this piece of research is the exploration of deceit in Spanish written communication. We have designed an automatic classifier based on Support Vector Machines (SVM) for the identification of deception in an ad hoc opinion corpus. In order to test the effectiveness of the LIWC2001 categories in Spanish, we have drawn a comparison with a Bag-of-Words (BoW) model. The results indicate that the classification of the texts is more successful by means of our initial set of variables than with the latter system. These findings are potentially applicable to areas such as forensic linguistics and opinion mining, where extensive research on languages other than English is needed.

The article is devoted to the study of some problematic issues of authentication of digital evidence in the course of consideration of cases by the International Criminal Court. The authors note that in the digital era, new technologies and the development of computing power have changed the nature of potentially relevant evidence which is assessed in international criminal law. The International Criminal Court is currently insufficiently prepared to address the issues of authentication of digital evidence, i.e., to determine the reliability of this type of evidence. The purpose of the article is to: (1) outline the challenges and dangers of the ICC's current approach to establishing the reliability of digital evidence; (2) study scientific approaches to the authentication of digital evidence in criminal proceedings; and (3) establish the need to establish the most pragmatic approach to determining the reliability of digital evidence in the future. The article outlines the challenges and dangers of the ICC's current approach to authentication and verification of digital evidence, examines the discussions among scholars on the issues outlined, and identifies recommendations for improving the Court's work and its ability to verify the reliability of digital evidence. The general approach of the ICC to the admissibility of evidence is defined, which provides for a consistent three-part test in which each of the following criteria must be met: 1) relevance: According to Articles 64(9)(a) and 69(4) of the Rome Statute, as well as the Rules of Procedure and Admission of Evidence, evidence is considered relevant if "the evidence produced makes the existence of the fact in question more or less probable". In other words, evidence may be considered relevant if it is "prima facie" ("at first glance") relevant to the case; 2) sufficiency: Evidentiary value is generally understood to mean whether the evidence is sufficiently useful to prove an important part of the trial. In essence, probative value measures the extent to which the proposed evidence may affect the determination of a fact or issue. The court must balance the probative value of the item against its prejudicial effect on the accused; 3) weighing probative value and prejudicial effect: According to Rules 69(4) and 63(2), the evidence provided must be "sufficiently relevant and probative to outweigh any prejudicial impact or effect that its admission may have". In other words, the weight given to the evidence must fully respect the rights of all parties and not be manifestly unfair to the prosecution or defense, nor prejudicial to the overall fairness of the trial. The author concludes that the ICC should seriously consider the following recommendations: (1) appoint an eCourt User Group to lead efforts to improve algorithms and continuously develop authentication issues; (2) expand the technological advisory role of the Scientific Advisory Board; (3) establish regular trainings and seminars to enhance the technical competence of judges; and (4) increase the transparency of the Scientific Advisory Board and the eCourt User Group.


Technocentric developments often result in creating a socio-spatial duality in different contexts, forming a place identity with contesting nature of the global and local settlements. The location of technocentric campuses in the urban periphery results in a haphazard development with little response to the context, also resulting in social strife and generating possibilities of marginalisation and gentriication of the local communities in near future. This will affect the urban life due to a discontinuity in the urban realm. The current transformations include functional change of existing residential units into mixed-use commercial and lodging facilities and, conversion of vacant plots into high density residential and commercial functions. The transformations seen at the site of the case study also include the conversion of the earlier dead bypass stretch into a highly active corridor with restaurants, informal eateries, and hang out areas targeting the techie population which adds to the changing urban identity of Kazhakuttom. This paper attempts to envision the future development and urban identity of Kazhakuttom as the new economic district of Trivandrum city as a favourable work-live-entertainment environment with support facilities, while also incorporating local aspirations to ensure social and spatial continuity. The methodology involved a detailed macro and micro level primary study and analysis of Kazhakuttom so as to identify the issues. The methodology included correlating the primary study with literature study on concepts and theories of identity, glocalization, and hybridization.

Nephrite is mainly sold on the market in China(Xinjiang,Qinghai Province and Liaoning Province),Russia,Canada,South Korea and other places at present.The main kinds of jade are white jade,grayish jade,gray jade and green jade.Jade from different origins show the similar characteristics in mineralogy and petrology.However,it shows subtle differences in nephrite appearance from different origins due to the differences in mineral assemblages and tremolite crystallinity,particle size and arrangement. This study is aiming to find the common and different characteristics of nephrite from various orgins and to provide a more detailed theoretical guidance for identification.Using polarizing microscope,X-ray powder diffraction,scanning electron microscopy(SEM)and ICP-MS,the chemical compositions,mineral assemblage,microstructures and appearance characteristics of the main varieties of nephrite are studied.The results show that the chemical compositions and main minerals of nephrite from different origins are similar.However,there are differences in trace elements and secondary minerals,which could be a certain significance for identification.In general,white jade and grayish jade from Xinjiang,high quality white jade from Qinghai Province and Russia are flet-like cryptocrystalline blastic texture with high content of tremolite,where fiber structure is small and closely intertwined.Therefore,the jade is fine,glossy in appearance.While gray jade from Xinjiang,part of white jade,grayish jade from Qinghai Province,white jade from Xiuyan and South Korea are micro-fibrous interlocking texture,microfibre flaky blastic texture,microfibre granular crystalloblastic texture and porphyroblastic texture.Content of tremolite in jade from those areas is relatively low,and fibers are coarse with large gap,which lead to rough texture and poor gloss in appearance and toughness decreasing.The structural types and crystallinity of jasper from Xinjiang,Russia and Canada are similar and it shows little difference in appearance characteristics.


Heidegger paid special attention to the philosophy of some pre-Socratic authors in order to show the pre-metaphysical view of the relationship between truth and being. In this article the author tries to analyse the conferences that Heidegger held on Parmenides in Freibourg during the «Winter Semester» of 1942-1943. The analysis focuses on the question of truth (α`ληθeια) as the key in shaping a concept of humanity that makes it possible to overcome nihilism in the form of modern subjectivity.


This paper investigates the effect of real exchange rate misalignment and volatility on Malaysian import flows during 1991:Q1 to 2003:Q4. A measure of the quantitative proxy of the real exchange rate misalignment is constructed using the Natural Real Exchange Rate (NATREX) equilibrium model, whereas the volatility of real exchange rate is generated from the GARCH model. This paper differs from existing literature as the effects of exchange rate misalignment significantly hastened the level of Malaysian imports for period of the study. The empirical results also show that the exchange rate volatility has merely promoted the Malaysian imports during the crisis period. This suggests that the exchange rate misalignment and volatility are important determinants in inspiring Malaysian import flows, especially during the 1997 Asian financial crisis.


This paper studies the impact of GaN channel thickness scaling on the DC and RF performance of InAlN/GaN high electron mobility transistors (HEMTs) with 30–230 nm gate length. Thin GaN channels increase the charge confinement, which improves immunity to short-channel effects. However, as the channel thickness scales down, mobility degradation is observed due to additional interface and alloy scattering caused by the InGaN back barrier layer. Due to this higher interface scattering, the effective electron velocity decreases when thinning down the channel from 26 nm (ve=1.45 × 107 cm/s) down to 4 nm (ve=1.16 × 107 cm/s).


The inventive step is nowadays generally regarded as the key threshold variable ensuring balance in patent systems, effectively operating as a proxy to ensure benefits exceeding costs. Despite the active debate about the current inventiveness standard, there has been little attempt to measure it. The study reported here uses data from recently granted Australian business method patents, and tests these inventions against an economic rather than a legal yardstick. The 72 cases were assessed for their contribution to knowledge or know-how— none were found. The data are organised here to throw light on the key reasons underlying the monopoly grant to these uninventive patents. The first issue addressed is whether there was a problem identifying existing knowledge. In 12 out of 69 cases no novelty or inventiveness objections were raised, either in Australia or for parallel overseas applications (USPTO or EPO). Lengthy and complex drafting contributes to the few cases where existing knowledge did not lead to inventiveness objections. The cases demonstrate that a range of procedural rules operate to allow grant of a patent monopoly to many 'inventions' that do not offer any advances in knowledge or know-how, and so provide no social benefits. The rules and procedures arising from the research are: • the 'reverse onus of proof'—that the patent office has to prove obviousness, not the applicant inventiveness; • the 'suggestion' test for assessing combinations of existing elements; • amendment of specifications to allow narrow differences from the existing knowledge identified by examiners; • acceptance of trivial differences, sometimes simply semantic, to determine inventiveness; • failure to apply the analogous use test to processes, despite its obvious suitability for this purpose; and • policy presumptions that the solution to a trivial problem is inventive, or that ideas themselves merit monopolies. Many of the cases in the dataset have parallel overseas applications and review of the communications between applicants and examiners at the EPO and the USPTO throws light on overseas grant practices. While half the applications that have been assessed by the USPTO have been rejected, the other half have been accepted, and the procedural problems identified in Australia are also evident in the USA. The situation at the EPO is more complex, as rejection is usually based on the lack of a "technical effect". But three very trivial software systems have been granted patents by the EPO. It is unclear how they managed to pass either the technical effect test or the inventiveness test. As it is a range of rules and procedures which have allowed the grant of these patents, it seems likely that equally trivial patents are being granted in other fields of technology. How high is the inventive step? Some empirical evidence


The principal objective of this thesis is to study the extratropical winter low frequency variability of northern hemisphere from a PV perspective, which is physically more revealing than the 500 MB pressure surface geopotential height field used by Dole and Gordon (1983), Dole (1986) and Neilley (1990) and gives us a complete picture about the dynamical state of the atmosphere. We characterize the recurrent low frequency persistent anomaly patterns in terms of the phase relationship between potential temperature on tropopause (Otrop) and 850 MB (0850) themselves and with the underlying land/sea contrast and orography. Using criteria derived from Otrop and 0850 idealized picture, PAC(+), PAC(-) and ATL(+) cases are identify from 15 years of NMC global analysis data. The cases compare well with Neilley (1990) and the difference is discussed. We also present the composite cases to show that the persistent cases identified in this thesis are consistent with the persistent anomalies in the literature. Detailed examination of observational data reveals that: 1). PAC(+), ATL(+) and PAC(-) cases have duration from about one week to one month, and are basically low frequency phenomena in the sense that daily maps resemble the case average. 2). PAC(+) (ATL(+)) cases are characterized by a broad warm potential temperature ridge over the Pacific (the Atlantic) on both tropopause and 850 MB, which is compatible with the land/sea thermal contrast. They look like thermally equilibrated responses in Marshall and So (1990) because the warm air tends to stay over the ocean and cold air tends to stay over the land in the winter. The configuration of positive persistent cases effectively steers synoptic systems to the north of the ridge and maintains its persistence. 3). For PAC(-) cases, Otrop and O850 have phase relationship out of phase with the land/sea thermal contrast, but the position of the ridge is compatible with the stationary planetary wave pattern due to the Rockies. This stationary forcing is evident when the flow is not thermally equilibrated. 4). PAC(+) and PAC(-) states may act as two natural attractors and the atmosphere oscillates between these two states regionally. 5) for ATL(-) cases, Otrop has concentrated contours over the Atlantic and divergence over the Europe, but surface temperature still have warm over the ocean and cold over the land. The ATL(+) cases look more like intense zonal flow with synoptic systems embedded within it. Its low frequency characteristics is not as evident as the PAC cases and ATL(+) in the sense that twice daily maps can be very different from the case average. The out of phase relationship of 0 trop and 0850 implies rapid development rather than persistence. Due to the lack of large mountains, the Atlantic region doesn't have another natural attractor for persistence other than the thermally equilibrated state ATL(+). The oscillation is between the thermal equilibrated response and intense zonal flow. Thesis Supervisor: John Marshall Title: Professor

In Reply.— As reported in our discussion of study methods, the PIOPED ventilation scans included left and right posterior oblique views in addition to the posterior views. The PIOPED investigators considered the use of aerosol and of xenon 127 for ventilation scans during the planning phase for PIOPED. In comparison to xenon 133, aerosol has not been shown to be a superior diagnostic agent. 1 Because of aerosol's greater cost, the limitations Dr Boxen describes, and the lack of evidence of diagnostic superiority, aerosol was not used. Although xenon 127 has some desirable characteristics, at the time of the PIOPED planning phase it was much more expensive than xenon 133 and was distributed by only one commercial supplier, which made it impractical for use in PIOPED. We do not know of any large series conducted to establish whether xenon 127 is indeed superior as a diagnostic agent. The PIOPED investigators took


Objective: The coronavirus disease 2019 (Covid-19) has significantly affected human health around the world, causing many complications. However, it is not fully understood how the body compositions of individuals affected in the short or long term after disease. In this study, we aimed to show the effects of Covid-19 on body composition and phase angle values, using Bioelectrical Impedance Analayser.
Methods: Subjects were selected from individuals in the 18-60 age group, who had survived COVID-19 disease. 33 individuals who had survived it 1-3 months ago, and 30 individuals who had survived it 3-6 months ago were included in the study.
Results: Effects of COVID-19 on basal metabolism and body composition and the ratio of damaged cells in the body after the disease were determined. Basal metabolic rate, lean body mass, body cell mass, total body fluid, intracellular fluid, and phase angle values were found to be significantly changed in the 3-6 months range compared to that of 1-3 months.
Conclusion: These results indicate that the basal metabolism and body composition parameters of the body become better, and the proportion of damaged cells decreases as time goes on after suffering COVID-19, reaching values close to normal in 1-3 months and quite better values in 3-6 months. It can be concluded that, although covid-19 influences body composition parameters and cell integrity in survivors of Covid 19 disease, these effects are limited to 3-6 months.


Abstract Three glaciers in southern Norway, with very different mass-balance characteristics, are studied with an energy-balance model of the ice/snow surface. The model simulates the observed mass-balance profiles in a satisfactory way, and can thus be used with some confidence in a study of climate sensitivity. Calculated changes in equilibrium-line altitude for a 1 K temperature increase are 110, 108 and 135 m for Nigardsbreen, Hellstugubreen and Alfotbreen, respectively. The corresponding changes in mass balance, averaged over the entire glacier area, are −0.88, −0.715 and −1.11 m year−1 (water equivalent). Runs with an ice-flow model for Nigardsbreen, to which calculated mass-balance profiles arc imposed, predict that the front will advance by 3 km for a 1 K cooling, and will retreat by as much as 6.5 km for a 1 K warming. The response to a 10% increase in precipitation would be a 2 km advance of the snout, whereas a 4 km retreat is predicted for a 10% decrease. This large sensitivity (as compared to many other glaciers) is to a large extent due to the geometry of Nigardsbreen.


Regression models are one of the most important machine learning models for time-series data prediction. However, multicollinearity is also an obstacle of accuracy. The most straightforward approach (called Type 1) to address the collinearity problem is to eliminate some related variables before modeling. The other approach uses new algorithms that can handle the situation well. Type II algorithms, including Linear Regression, Ridge Regression, Lasso Regression, Elastic Net Regression, Linear Regression with Polynomic features, Decision Tree Regression, and Random Forest Regression, are applied to construct a prediction model directly. The comparison between type 1 and type 2 is shown in this paper. This research aims to compare the efficiency of various regression model algorithms on datasets that consist of collinearity. The main contribution of this paper is simplicity that retains high accuracy. Elastic Net Regression offers the best choice with R square on the test data of 92%.


Abstract : The refining industry in Iran is facing a crisis caused by a growing shortfall in production capacity for gasoline and other light fuels to meet rapidly growing domestic demand. The industry is locked into a repetitive cycle of decline due to under-investment in new facilities and total capacity, massive government energy and automotive subsidies that encourage continued growth in demand, and a poor investment climate that discourages badly needed foreign investment in the refining industry. The shortfall in refining capacity causes the government to import fuel, the cost of which is growing beyond the government's ability to control it. This refining crisis creates an opportunity for the United States and its allies to exercise strategic patience in trying to influence the Iranian government's behavior in a direction more favorable to their interests. The Iranian government has historically demonstrated an ability to act pragmatically to stave off economic dislocation. It is reasonable to assume that they will do so again in response to the economic threat posed by the refining crisis. While a policy of strategic patience carries risk, the available evidence demonstrates that the current program of sanctions and economic pressure are unlikely to force a favorable change in Iranian behavior.


This paper examines the role of the place of living (rural or urban) and its socio-cultural context in determining the parent-adolescent child value similarity. We interviewed representatives of two generations: parents and adolescent children from 90 families in Moscow and 62 families in villages (n=304 people). Our findings indicate the influence of the socio-cultural context on the transmission of values. Conservation values are primarily transmitted from parents to children in more traditional, rural contexts. Openness to change, Self-Enhancement and Self-Transcendence values are transmitted from parents to children mainly in urban contexts. The perceived psychological closeness between parents and adolescents (adolescent perception) predicts value transmission in urban and rural contexts. All values of adolescents are more similar to the values of peers than parents, in both urban and rural contexts.

Here, thermodynamic stability and lithium storage properties of double transition metal M2TiAlC2 o-MAX phases (M = Cr, V, Mo, Nb, Ta, Hf, Zr, Sc, Y, La) are theoretically investigated by density functional theory (DFT) calculation. M2TiAlC2 with a larger M atomic radius shows larger interlayer space that may benefit the Li-ion intercalation. A promising theoretical capacity of 276.87 mAh g-1 is predicted for Sc2TiAlC2. The low Li-ion diffusion barriers (0.57–0.64 eV) for M2TiAlC2 indicate the possibility to achieve fast Li-ion diffusion that is crucial for designing high-power batteries. This work provides opportunities to explore MAX phases as promising Li-ion storage materials. GRAPHICAL ABSTRACT IMPACT STATEMENT This work investigates the thermostability and lithium storage properties of double transition metal o-MAX phases by DFT calculation and provides a guideline for exploring MAX phases for lithium storage applications.

Abstract : We describe efforts to create corpora to support and evaluate systems that meet the challenge of speaker recognition in the face of both channel and language variation. In addition to addressing ongoing evaluation of speaker recognition systems, these corpora are aimed at the bilingual and crosschannel dimensions. We report on specific data collection efforts at the Linguistic Data Consortium, the 2004 speaker recognition evaluation program organized by the National Institute of Standards and Technology (NIST), and the research ongoing at the US Federal Bureau of Investigation and MIT Lincoln Laboratory. We cover the design and requirements, the collections and evaluation integrating discussions of the data preparation, research, technology development and evaluation on a grand scale.


Movement is the main characteristic making glacier ice differ from other ice in nature.Observation of surface flow velocity is a basic method to study the glacier movement.Tomur Peak is the region with the highest concentration of glaciers in the Tianshan Mountains,and the glaciers are the main water resources for Aksu Municipality.Because of the important role of glaciers in local water resources,to study the current state and future evolution of the glaciers and glacial runoff in the municipality is urgent need.However,the study is hampered,because there is almost no observed glacier movement data here.To fill the blank,in August 2008,a large-scale scientific expedition was taken by Tianshan Glaciological Station,during which 21 stakes were set on the glacier for glacier flow velocity and mass balance observations.The Global Positioning System was applied to monitor the stake position.In July and August 2009,the measurement of the position of stakes was taken repeatedly.According to all the measured data,the features of surface flow velocity of the glacier is obtained,showing that the maximum horizontal surface velocity was around 73.4 m·a-1,averaging at 47.1 m·a-1 in the tongue area.The spatial distribution of velocity was highly correlated with geometry of the glacier surface.There is obvious seasonality of the surface flow velocity.In detail,the velocities in the ablation season are significantly higher than that in non-melting season.In addition to the contribution of basal sliding,the ablation season velocity is also impacted by the ablation at the glacier bottom.Comparing to the corresponding features of the urumqi Glacier No.1,the velocity of Qingbingtan Glacier No.72 is much higher,the mass transport by movement is more active,and the basal sliding is more significant.Generally,the velocity features of the Qingbingtan Glacier No.72 are similar to those of maritime glaciers in China.


The traditional data mining method of students' physical health has some problems, such as low recall rate of data mining, long mining time, and poor mining accuracy. Therefore, this paper proposes a data mining method of college students' physical health for physical education reform. Using association rules to construct the correspondence between the fitness test data, the fitness test data can be classified and the data training model can be built. The decision tree of data attribute was built, and the physical health data was segmented by the segmentation technology. The information entropy of health data was calculated by the decision tree, and the information gain of health data sample set was obtained. The C4.5 algorithm was used to improve the ID3 algorithm. The improved decision tree was used to obtain the physique data splitting attribute, and the information gain rate was obtained by the ID3 algorithm correction. The

 k

 -means algorithm is used to divide the data into clusters, according to which the physical health data mining of college students is realized. Experimental results show that the recall rate of the physical health data mining method proposed in this paper is as high as 96%, the data mining time is only 3 s, and the accuracy of data mining is as high as 98%, indicating that the method proposed in this paper can improve the physical health data mining effect.
