The intersection of technological, social, economic, political and environmental factors in the late 20 th century has reshaped the meanings and impor- tance of local environmental knowledge and associated genetic resources, as well as of local forms of organi- zation and control. This new social context has created new opportunities for the growth and consolidation of ethnobotany, both in terms of its theoretical sophistica- tion and its social relevance. Indeed, ethnobotany's position at the human-environment interface, as well as at the interface between different social groups, kno- wledge systems and academic disciplines, provides a strategically privileged position from which to engage with many of today's complex social and environmen- tal problems; for example by facilitating dialogue and exchange between different specialists and stakehol- ders, by generating new forms of knowledge, and by developing new mechanisms for dialogue and exchan- ge in a world that, while increasingly interconnected, is also riddled with conflict. This new context and its associated expectations also place new philosophical, ethical, epistemological, methodological and institutio- nal demands. The related issues of interdisciplinarity, interculturality and participation are likely to remain central concerns to ethnobotanists striving to bridge different kinds of social divides, in a world permeated by contingency, change and inequity.


The major research scope was to study the effect of various forms of potassic fertilizers and the ratio of N, P2O5 and K2O. During the experimental period, quantitative measurements of growth vigor and flowering were taken. At the end of experiments, the optimal levels and sources for those high-priced flower crops would be formulated for future production. A new formulation 12-5-17-2 (MgO) of compound fertilizer was manufactured sod showed positive effect on increasing yield and improving quality of both chrysanthemum and gladiolus. Two new products with formulations 5-5-5-2 (MgO)-10(Humic acid) and 16-8-12-3(MgO) were both able to increase the yield of leather fern.

Background: Pearl millet is also called as the "Powerhouse of Nutrition" as it consists of most of the important nutrients in good quantity and quality which are required for maintaining healthy life. Indiscriminate use of high analysis chemical fertilizers results in the environment pollution which is detrimental to the sustainability; there is an urgent need for adoption of farming practice which ensures sustainability, good soil, human and environmental health.
Method: A field experiment was taken for three consecutive years during kharif season of 2018 to 2020 at Agronomy Research Farm, Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Rajasthan to study the impact of various sources of organic nutrients and bioinoculants on growth and productivity of pearl millet. The treatments were comprised of chemical fertilizers, organic manures and microbial biofertilizer consortia (consisting of Azotobactor, Azospirillum and phosphate solubilizing bacteria) commercially branded as Biomix, which were tested in randomized block design with three replications.
Result: All the treatments including farmyard manure (FYM) and vermicompost with and without Biomix had significant effect on soil properties, growth andyield parameters and yield of pearl millet. The pooled data clearly showed that recommended dose of fertilizer (RDF) recorded significantly higher grain (3494 kg/ha) and stover (8612 kg/ha) yields of pearl millet and found at par with treatments T6: 100% RDN through FYM + Biomix; T7: 75% RDN through FYM + Biomix; T8: 100% RDN through vermicompost + Biomixand T9: 75% RDN through vermicompost + Biomixover rest of the treatments. With respect to economics T6 (100% RDN through FYM + Biomix) recorded highest net returns of Rs. 75602 and B:C ratio (4.14) followed by treatment T7 (75% RDN through FYM + Biomix). Continuous application of organic manures with biofertilizers had also significant improvement on soil OC (0.39%), phosphorus (54 kg/ha), potash (310 kg/ha), Zn (0.92 ppm) and Fe (6.92 ppm) over initial soil status.


Continuous free‐flow electrophoresis (CFE) provides the biochemist with a powerful technique for preparative‐scale purification of labile biomolecules. However, solute resolution in the classic CFE is limited by the deleterious effects of diffusion, electroosmotic dispersion, and connective dispersion. These problems can be overcome in the CFE by continuously recycling effluent through the chamber in a manner which allows complete recovery of undiluted product at arbitrarily high purities.

This essay explicates five themes from We Hold These Truths. Specifically, it seeks to: (1) compare Murray's treatment of contemporary America's loss of a public philosophy to similar arguments made by important non-Catholic journalists and political theorists in his day; (2) bring Murray's account of the Christian roots of the liberal tradition into conversation with the view that the liberal tradition is specifically modern; (3) explore the significance of Murray's famous interpretation of the religion clauses of the First Amendment as entirely practical "articles of peace"; (4) critically engage Murray's account of the thought of the founders and explore the motivations underlying this account; and (5) relate Murray's account of the natural law theory undergirding the American democratic experiment to the political theory informing the Declaration of Independence and Lincoln's re-founding of the American regime.


Like the lovers of Roman elegy, the speaker of C. 1.19 claims to be dominated by his beloved. As in elegy, however, this "inversion" is a sham. The speaker retains control over his beloved while expressing his secret hostility toward her. Associating Glycera's body with toxic, uncontrolled nature, the lover claims that he risks harm simply by gazing upon her. He attempts to control his unruly object of desire by identifying her as material for his poetry, by immobilizing her as a statue, and by symbolically killing/penetrating her in the ode's closing sacrifice.


Combining literary criticism and fiction, Crane assumes the narrative voice of one of William Faulkner's most omnipresent characters, county attorney Gavin Stevens, and interprets events in terms of their significance for the history of Yoknapatawpha county and thus for the entire canon of Faulkner's work. Thorough indexing and cross-referencing enables the reader to trace any character or series of events.

2007). In addition, the polyphenols extracts in the presence of ascorbic acid increased the anthocyanin content compared to the control and treatment sample (T 2 ) and also increased the stability of anthocyanin content during storage. Among the co-pigments used (polyphenols extracts), T 3 treatment, which contained 30% w/w green tea, had the highest amount of anthocyanin compounds (260/49 mg / l), which could be due to the phenomenon of co-pigmentation. In other words, the higher anthocyanin stability upon green tea addition was due to co-pigmentation, inhibited the ability of water molecules to attack the flavylium ion and caused color loss (Kopjar et al. 2014). According to the obtained results of Degradation index, treatment (T 3 ) with addition of ascorbic acid and green tea extract had the lowest, while the sample (T 2 ) with the addition of ascorbic acid only had the highest degradation index. Those results were in correspondence with the results for anthocyanin content. After preparation, samples with green tea extract addition had the highest anthocyanin content and the lowest degradation index, which means that anthocyanins were more stable. During storage, degradation of anthocyanin occurred and the destructive index increased (Piližota et al. 2012). In terms of total phenolic content, under the defined conditions, T 3 treatment containing of green tea extract (30% w/w) had more phenolic compounds than other treatments (5.78 mg/l) and T 2 treatment containing ascorbic acid had the lowest polyphenol content (2.85 mg/l). Whereas T 3 treatment had more polyphenolic compounds than other samples, anthocyanins and polyphenol structures could be more exposed to each other and more effective copigmentation occurred. Conclusion: The results revealed that by using plant extract/polyphenol, solutions could significantly increase the stability of anthocyanins. Among these extracts, green tea extract was the most effective extract in inhibiting the destruction of anthocyanins.


With the rapid development of photoredox catalysis, numerous concepts for asymmetric induction were successfully and broadly adapted from polar two-electron transformations to radical chemistry. While this applies to organocatalysis or transition metal chemistry, asymmetric ion-pairing catalysis remains a niche application within light-driven reactions today. This perspective gives an overview of recent examples, strategies, and their application in stereoselective transformations at the interface of ion-pairing and photo(redox) catalysis.


Abstract Field experiments were conducted in 1991 and 1992 in Georgia to determine the efficacy of DPX-PE350 when applied either preplant incorporated (PPI), preemergence (PRE), and early postemergence (EPOST) at rates of 40, 80, or 120 g ae ha-1 for weed control in peanut. Species evaluated included coffee senna [Cassia occidentalis (L.)], Florida beggarweed [Desmodium tortuosum (Sw.) DC.], prickly sida (Sida spinosa L.), smallflower morningglory [Jacquemontia tamnifolia (L.) Griseb.], sicklepod (Cassia obtusifolia L.), and yellow nutsedge (Cyperus esculentus L.). Sicklepod was controlled better with either PPI or PRE applications than with EPOST. Coffee senna control was more consistent with DPX-PE350 applied EPOST. DPX-PE350 controlled prickly sida and smallflower morningglory regardless of application method and rate. DPX-PE350 did not control Florida beggarweed when soil applied. PPI applications were more injurious to peanut than PRE or EPOST applications. Peanut yields tended to decrease as DPX-PE3...


Current evaluation datasets for face detection, which is of great value in real-world applications, are still somewhat out-of-date. We propose a new face detection dataset MALF (short for Multi-Attribute Labelled Faces), which contains 5,250 images collected from the Internet and ~12,000 labelled faces. The MALF dataset highlights in two main features: 1) It is the largest dataset for evaluation of face detection in the wild, and the annotation of multiple facial attributes makes it possible for fine-grained performance analysis. 2) To reveal the `true' performances of algorithms in practice, MALF adopts an evaluation metric that puts stress on the recall rate at a relatively low false alarm rate. Besides providing a large dataset for face detection evaluation, this paper also collects more than 20 state-of-the-art algorithms, both from academia and industry, and conducts a fine-grained comparative evaluation of these algorithms, which can be considered as a summary of past advances made in face detection. The dataset and up-to-date results of the evaluation can be found at http: //www.cbsr.ia.ac.cn/faceevaluation/.


Clock-gating and power-gating are the most widely used solutions for reducing dynamic and static power. They can be potentially integrated so that clock-gating conditions can be used to control the power-gating circuitry thus also reducing static power. This integration becomes however difficult when applied in an industrial design flow. Even if both clock and power-gating are supported by most commercial synthesis tools, their combined implementation requires some flexibility in the back-end tools that is not currently available.


A smart phone mobile application (app) has been created to assist landscapers, contractors and home owners in designing, installing, and maintaining rain gardens. It seeks to address water quality issues by taking advantage of the rapidly increasing use of mobile devices to access educational information and complement existing in-person educational efforts to address water quality issues. In addition to a series of tutorials, the app includes several interactive tools to help users size their garden, evaluate their soils, and select proper plants. The initial version of the app is focused on Connecticut, but a national version is planned.


Obesity is an unresolved public health problem, but it causes a variety of serious medical complications, reduces the quality of life and leads to increased morbidity and premature death. The article aimed to identify current epidemiological data on the prevalence of obesity by body composition measurements among adults older 15 years in the Southern regions of Kazakhstan. Research was conducted within the framework of scientific and research work "Comprehensive prevention of overweight and obesity epidemics in Kazakhstan". For present research we randomly selected 30 households from each of 18 Southern Kazakhstan Region clusters, making together 540 households. Body composition measurements include body mass index based on reported weight, height and additional measurements: waist and hip circumference

: The establishment and maintenance of protected areas is the backbone of global 15 conservation strategies to halt biodiversity loss. However, despite the more than 200,000 legally 16 designated protected sites worldwide, the rate of species extinction has not decreased, for which 17 some debate the real effectiveness of protected areas to preserve biodiversity. Using data from 18 tropical areas, many studies have attempted to test the effectiveness of protected areas by 19 comparing species richness in protected and neighbouring unprotected sites, without reaching a 20 consensus. Here, we extend this line of research with data from temperate deciduous forests 21 occurring inside and outside Picos de Europa National Park and Biosphere Reserve (NW Spain). 22 Specifically we compare data from Mixed broadleaved woodlands, Beech forests ( Fagus sylvatica 23 L.) and Pyrenean oak ( Quercus pyrenaica Willd.) forests. We conducted botanical inventories and 24 recorded ecological data from 25 0.2-ha concentric plots distributed in forest commons inside the 25 reserve and from other 25 similar plots established in neighbouring not protected forest commons. 26 Data were evaluated using modelling methods and used to construct a set of ecological indicators.


Model calculations and experiments have been performed to explore the modes of photoacoustic signal generation from highly porous powders. These indicate that two modes of signal generation are important: (i) a thermal mode resulting from heating of the sample and conduction to the transducer gas above the sample, and (ii) a pressure mode resulting from the volumetric expansion of the interstitial gas in the porous sample. For highly porous materials, such as silica, the pressure mode can dominate the photoacoustic signal. Under conditions where the pressure mode is dominant, the frequency dependence of the acoustic magnitude and phase is similar to that of a homogeneous sample in photoacoustic saturation, however, the photoacoustic signal will still scale with absorption coefficient in this regime. The pressure mode of signal generation can be attenuated by compaction of the powdered sample to reduce the porosity. Unambiguous determination of photoacoustic saturation is shown to require measurements as f...


We propose a primary color overlapping method for increasing the brightness of projection system. It consists of a projected optical system based on 0.55 inch diagonal digital micro mirror device panel and a red, green, blue LED light source. This color overlapping method synthesized secondary colors of yellow and cyan instead of primary colors of red, green, and blue. By our method, the brightness of projected image was improved about 30 percent compared to a non-color overlapping method in a projection system with LED.


The aim of this project was to analyze two model solutions for connecting solar heating system to the district heating system in Storvreta in order to obtain the largest solar heat potential. The two model solutions were either households that was considered as a decentralized model, or solar plant that was considered as a centralized model. In addition to the technical aspects, there were also economical aspects that were considered to find the most economical feasible connecting solution. The conclusion was that a decentralized connection would be used were the households uses mortgage loans. This would generate a total amount of heat of 4300 MWh where 2800 MWh would be used for seasonal storage. After 27 years the total income would have exceeded the total cost for the system.

Received: 27/7/2021 Soil samples in the waste dump of the lead-zinc mine in Hich village, Dong Hy district, Thai Nguyen province were collected and analyzed. The total Zn content in the soil samples was determined by plasma mass spectrometry (ICP-MS). Tessier's sequential extraction procedure was applied to extract and analyze the chemical fractions of Zn in soil samples. The obtained results showed that the total content of Zn in the soil samples ranged from 2305.4 ÷ 7479.1 mg/Kg, which was 7.7 ÷ 24.9 times higher than the permissible standards of the Vietnamese Ministry of environmental resources for industrial land. The results of chemical analysis showed that zinc exists mainly in the form of residues (F5) or bound to Fe/Mn oxides (F3) and minimally in the bonding organic fraction (F4). The geo-accumulation index (Igeo) has evaluated the content of Zn in the soil samples in the waste dump area of the lead/zinc mine with high and very high pollution levels. According to the Risk Assessment Index (RAC), the content of Zn in tailing soil samples is at medium and high environmental risk. Revised: 27/8/2021

This paper aims at exploring the drivers of entrepreneurial dynamism and performance in indigenous societies. In Mizoram (India) with a predominantly tribal population, the government has actively intervened to encourage entrepreneurship through policy incentives/subsidies. Yet, the region continues to lag behind in entrepreneurship development. In an attempt to explain this apparent failure of conventional policies to promote entrepreneurship in Mizoram (India), this paper explores the factors that could potentially determine entrepreneurial dynamism and performance in an indigenous society through the lens of their tribal culture and institutions. Our results show that tribal values are the prime drivers of entrepreneurial dynamism, while conventional traits and attitudes have no impact, disproving two dominant narratives. We also find that conventional subsidies have a negative impact on profitability, perhaps due a dampening effect of subsidies on dynamism.


Introduction Out-of-hospital cardiac arrest (OHCA) is a common, life-threatening event encountered routinely by first responders, including police, fire and emergency medical services (EMS). Current literature suggests that there is significant regional variation in outcomes, some of which may be related to modifiable factors. Yet, there is a persistent knowledge gap regarding strategies to guide quality improvement efforts in OHCA care and, by extension, survival. The Enhancing Prehospital Outcomes for Cardiac Arrest (EPOC) study aims to fill these gaps and to improve outcomes. Methods and analysis This mixed-methods study includes three aims. In aim I, we will define variation in OHCA survival to the emergency department (ED) among EMS agencies that participate in the Michigan Cardiac Arrest Registry to Enhance Survival (CARES) in order to sample EMS agencies with high-survival and low-survival outcomes. In aim II, we will conduct site visits to emergency medical systems—including 911/dispatch, police, non-transport fire, and EMS agencies—in approximately eight high-survival and low-survival communities identified in aim I. At each site, key informant interviews and a multidisciplinary focus group will identify themes associated with high OHCA survival. Transcripts will be coded using a structured codebook and analysed through thematic analysis. Results from aims I and II will inform the development of a survey instrument in aim III that will be administered to all EMS agencies in Michigan. This survey will test the generalisability of factors associated with increased OHCA survival in the qualitative work to ultimately build an EPOC Toolkit which will be distributed to a broad range of stakeholders as a practical 'how-to' guide to improve outcomes. Ethics and dissemination The EPOC study was deemed exempt by the University of Michigan Institutional Review Board. Findings will be compiled in an 'EPOC Toolkit' and disseminated in the USA through partnerships including, but not limited to, policymakers, EMS leadership and health departments.


The utility model relates to an optical fiber stickiness reducing device of an optical fiber ultraviolet ray curing furnace.

The utility model can reduce the inlet air entering in the curing furnace, the oxygen content in the curing furnace, and the optical fiber stickiness after being solidified by adopting the device of drafting air at the upper part and supplying air at the lower part, the oxygen content analyzer in the air draft mechanism and the nitrogen gas flowmeter and compressed air flowmeter in the air supplying mechanism are arranged and the monitoring are performed by connecting with the PC, thereby to ensure that the effect of the optical fiber reduction stickiness after being solidified via the curing furnace is better.


recommendations, most of which have been implemented in sections 11, 12 and 13. A detailed examination of these sections is beyond the scope of a note, but the following summary of their effect may be ventured. (1) The conviction of a person of a criminal offence may, in subsequent civil proceedings between any parties, be proved for the purpose of raising a presumption that that person committed that offence. (2) A finding in matrimonial proceedings in the High Court or a county court that a person has committed adultery may, in subsequent civil proceedings between any parties, be proved for the purpose of raising a presumption that that adultery was committed. (3) An adjudication in affiliation proceedings that a person is the father of a child may, in subsequent civil proceedings between any parties, be proved for the purpose of raising a presumption that that person is the father of that child. (4) The presumption raised in the foregoing situations is " persuasive," and casts a " legal" burden on any party seeking to displace it. (5) Proof that a person stands convicted of a criminal offence will, in defamation actions between any parties, be received as conclusive evidence that that person committed that offence. Part II also gives effect to recommendations of the Law Reform Committee (16th Report, 1967, Cmnd. 3472) relating to privilege in civil proceedings. The privilege against self-incrimination is extended, in civil proceedings, to cover incrimination of a spouse (s. 14). Privilege for certain communications relating to patent proceedings is afforded (s. 15). And a number of existing privileges (including those relating to the production of title deeds, exposure to forfeiture, communications between spouses, and questions tending to establish adultery in matrimonial proceedings) are abolished, except in relation to criminal proceedings (s. 16). The provisions relating to privilege and to the conclusiveness of convictions for the purpose of defamation actions are of immediate effect. The other provisions of the Act are to come into force at such time as the Lord Chancellor may appoint.


The major aim of the present study was to measure the ADC values of low grade and high grade tumors using diffusion weighted MRI, to determine their contribution to differential diagnosis and also to propose a cut off ADC value. A retrospective study was done in which the magnetic resonance imaging findings of 50 patients diagnosed as having intra-axial brain tumors on histopathology were studied co-relate the ADC values with the World Health Organization grade of the tumor. Higher grade tumors had lower ADC values ( 1.0 x 10 -3 mm 2 /s). Conventional MR was 100% accurate in differentiating grade I from higher grade tumors. Cut-off ADC of >1.4 X10 -3 mm 2 /s was 100% specific for grade I tumors though differentiation among the various grade I tumors was not possible on DWI. Using a cut-off ADC value of 1.0 X10


With the rapid development of power for the lithium battery formation,the problem of the formation control system of traditional lithium-ion batteries caused a lot of energy waste and pollution to power network is increasingly prominent,and the research of the efficient lithium battery formation equipment is becoming more and more important. In light of this problem,this dissertation proposed a lithium battery formation bidirectional AC /DC converter. The converter uses an improved form of voltage type PWM rectifiers and half bridge bidirectional DC /DC topology combination,and uses the MPC5604 B of the new generation of Freescale microcontroller as the core control chip and the voltage and current double closed-loop control algorithm to achieve the energy efficient two-way flow of lithium battery and the function of constant voltage,constant current charge and discharge. The experiments prove that the converter can achieve the basic purpose of the charge grid-side power factor to be 1 and the discharge gridside power factor to be-1.


The Government of Canada believes that a healthy democracy requires the active engagement of its citizens in understanding the economic, social, and environmental issues faced by the nation. In the Atlantic Region, Environment Canada has been actively working, for more than a decade, on helping citizens achieve this integrated view and providing local communities with the means to develop their own visions of sustainability. In this regard, the Atlantic Coastal Action Program (ACAP) has been one of Environment Canada Atlantic Region's greatest success stories. ACAP is a community-based program that promotes local leadership and action. For more than 13 years, ACAP activities have involved thousands of community residents working as volunteers in local and regional initiatives. Their successes include solving complex problems related to sewage treatment, toxic contaminants and water quality, building local capacity and, educating their communities on issues such as pollution prevention, monitoring, climate change, assessment and household hazardous wastes to name a few. By working as a partner with local communities rather than imposing decisions, Environment Canada has helped a diversity of communities to responsibly address environmental issues of "local interest." When communities realize that they can solve some of their own problems, they are empowered and can directly (or indirectly) influence decision-makers and policy makers. All of the ACAP groups have experiences in collaborative ecosystem management that have influenced local and/or regional decision-making. This paper outlines a number of these experiences, describes ACAP and its process as well as ACAP's influence within Environment Canada and the rest of the Atlantic Region.


Intracranial pressure and intracranial compliance When it is monitored, the ICP tracing is a ballistic waveform similar to the systemic arterial pressure curve (Fig. 1); it has a narrow "pulse pressure" and is expressed, by convention, as its mean measured in millimeter of mercury (mmHg). The normal mean ICP is generally between 5-10 mmHg, and it fluctuates to higher levels depending on physiological factors such as Valsalva maneuver and body position. The ICP wave contains three consecutive peaks in descending order, Peak 1 to 3 which are called percussion wave, tidal wave, and dicrotic wave, respectively. In addition, fluctuations in the baseline of the ICP waveform with breathing usually reflect a decrease in intracranial compliance, and it can occur and accentuate even before an elevation in the actual ICP value. This knowledge can be helpful in selected situations. For example, when a patient has fulminant hepatic failure observation of these subtle changes in the ICP waveform can signal the evolution of brain swelling before it is clinically apparent or the ICP has increased. In normal adults, the skull is a rigid container and contains brain parenchyma, fluid (interstitial and cerebrospinal), and blood (arterial and venous). In the average adult male the intracranial volumes approximate to 1,450 ml for the brain, 110 ml blood, and 65 ml of CSF. Expansion of any of these "compartments" or the addition of a space occupying process can lead to ICP elevation. The extent of the ICP elevation depends on many factors, most importantly the individual patient's intracranial compliance, that is, the unit change of intracranial volume per unit change of intracranial pressure (ΔV/ΔP). A high compliance denotes a system that will accommodate significant changes in volume (i.e., by diverting blood and CSF out of the cranium) without little increases in pressure and vice versa, a reduced compliance is found when the addition of small volumes to the intracranial space induces marked changes in ICP. Compliance or more technically correct described as its inverse, the brain elastance (change of pressure per change of volume (ΔP/ΔV), can graphically be depicted in the intracranial INVITED REVIEW


We apply the zero bias transformation to deduce a recursive asymptotic expansion formula for expectation of functions of sum of independent random variables in terms of normal expectations and we discuss the remainder term estimations.


This paper describes a load forecasting method for a large-scale VM-type thin client system. The purpose of this method is to deploy the client environment VMs for load balancing and energy-saving. For load forecasting, it is necessary to collect and analyze load data generated continuously and in large quantities, the so called "data stream," from all VMs. However, existing concentrated batch processing technology with a database is not suitable for processing such a data stream in real time due to the database access overhead. To address this issue, we propose an incremental forecasting algorithm and a distributed processing architecture. The former serially processes data on the route of data flow without storing it in the database. The latter distributes the processing load by hierarchizing the system. We also develop a prototype using our data stream processing framework and evaluate it. Our simulated experiments confirm that our proposed method achieves forecast processing on a large-scale VM-type thin client system in real time.


This study lays the foundation for reasons and ways to investigate the biased treatment of non-native characters in model dialogues in current English as a Foreign/Second Language textbooks. The literature review shows that although a plethora of studies have been conducted on gender bias in textbooks, speaker bias, or labeled nativism here, has been largely ignored. This research addresses this neglect by systematically applying parts of two frameworks previously used in analyzing textbooks for gender bias to four current EFL textbooks. The resulting data is quantitative in nature with some necessary description and qualification and shows that only one text avoids bias against non-native speakers. In the other texts, speaker bias is exhibited by non-native speakers being segregated or being only allowed to interact with a native speaker. In addition, non-native speakers are limited to non-expert roles in two texts. Based on these results, suggestions for further research are offered.

A number of investigators have utilized a variety of methods to identify the structural basis for the interaction of superantigens with the T‐cell receptor β‐chain. The previous studies strongly suggest that a region of the toxin near residues N23, Y61, Y91 and D209 is important for this binding activity. Examination of crystal structure data shows that these residues line the rim of one side of a shallow cavity in the toxin. In an attempt further to define the face of the staphylococcal enterotoxin B (SEB) molecule involved in the interaction with the β‐chain, we have employed a polymerase chain reaction (PCR)‐based, site‐specific mutagenesis method to generate amino acid substitutions of residues on the opposite side of this putative T‐cell receptor interaction cavity. Our results show that Y175 and N179 appear to be involved in the function of this superantigen, since each of several substitutions at this position exhibits a significantly reduced ability to induce T‐cell proliferation. At the same time, mutation of the proximal Y186 does not alter the superantigen activity of SEB. Binding analysis of these mutants shows that class II binding activity is not significantly altered. Analysis of the responding T cells shows that the mutant toxins maintain T‐cell receptor Vβ selectivity. However, responses of T cells bearing the Vβ8.1 allele appear to be particularly diminished. When viewed in the context of other results reported in the literature, our results suggest that the T‐cell receptor interaction site involves SEB residues which ring both the Y175/N179‐side and the N23‐side of a cavity on one side of the toxin molecule.


The invention discloses a preparation method of 3-nitro-N-ethyl carbazole, which is characterized by comprising the following steps: putting a sodium hydroxide solution, 3-nitro carbazole, a catalyst, part or all of ethyl bromide into a three-necked flask with a stirring and reflux condenser, slowly heating the obtained object to 35-40 DEG C, and dropwise adding the rest of ethyl bromide into the flask at the temperature; after the dropwise adding is completed, carrying out heating on the obtained mixture with the reaction, and controlling the temperature to be always below a boiling point of a system; determining that the reaction is completed when the 3-nitro carbazole conversion rate reaches more than 99.5%; carrying out cooling crystallization, filtration, washing and drying on the obtained product so as to obtain 3-nitro-N-ethyl carbazole. The method disclosed by the invention has the advantages that benzene is added as a solvent in general alkylation reactions, but no benzene is added in the invention, therefore, the application amount of ethyl bromide is relatively less, so that the method is simple in process, high in conversion rate and small in occupational hazards.


The first wave-length agrees with that of Exner and Haschek for the ordinary arc. Values for the spark pair by Hartmann are 4128.204 and 4131.040 respectively. Several attempts, some under powerful conditions of the tube-arc, were made to photograph the enhanced triplet AA4553, 4568, 4575, but nothing was obtained beyond a slight trace of the strongest line when the pair AA4128-31 was greatly overexposed. While disappointing as to getting these much needed wave-lengths, this result is of interest as showing that the pair and the triplet require very different degrees of excitation, which is not evident from the condensed spark, where both groups are strong. It is also in line with the theoretical evidence that the triplet belongs to the second stage of ionization. A stellar spectrum which shows the pair relatively strong may be expected to be of later type than one in which the triplet is of high intensity. Arthur S. King.


Background Solid organ transplantation is a valid treatment option for selected patients with organ failure due to an underlying telomeropathy; however, the feasibility of multiple-organ transplantation if several organs are compromised is unclear. Methods We describe 2 patients with telomeropathy due to heterozygous telomerase RNA component or telomerase reverse transcriptase mutation, who successfully underwent serial or combined liver and lung transplantation for concurrent liver fibrosis/cirrhosis and pulmonary fibrosis. Results Despite a challenging posttransplant course, long-term outcomes were favorable, with both patients doing fine now, respectively, 12/20 and 24 months after multiple-organ transplantation. Conclusions To our knowledge, this is the first report of multiple solid organ transplantation in documented telomeropathy. These cases highlight current difficulties of timely diagnosis, therapeutic approach, and postoperative complications in telomeropathy patients in whom several organs are affected.


Practice teaching in the college experiment bases is an important part of the higher education for teachers so it is quite necessary to make a study about this problem. In this article, I have discussed seven tasks, three principles and three directions about the college experiment bases where the teachers guide the students to do their practice teaching, for the purpose that it should do some good for the problem solved.


In this paper, we focus on the problem of H-infinity control for a class of nonlinear systems described by the Takagi-Sugeno (T-S ) fuzzy descriptor model with multiple time delays and disturbance. The descriptor type of Lyapunov-Krasovskii functional is employed to analyze the H-infinity stability, then a state feedback H-infinity controller is determined, which ensures that the closed system is quadratic ally stable and guarantees the H-infinity performance. The sufficient conditions for the solvability of this problem are presented in terms of linear matrix inequalities (LMIs). Finally, a numerical example is provided to demonstrate the application of the proposed method.


The article summarises the main findings of the Institution of Highways and Transportation Working Party on the availability and demand for high specification aggregates in the United Kingdom. The study showed that a wide range of existing and potential resources were available in Britian. The quarrying industry is able to meet the present demand from a number of specialised hard rock quarries. There are regional imbalances between supply and demand because of the distribution of geological resources and centres of population. This results in the long-distance transportation of aggregates from one region to another. The importance of the materials in maintaining safety standards on heavily trafficked roads indicate a need for the development of new resources over the next 10 to 20 years with a probable rise of around 15 to 20 per cent compared with 1991 levels. Current road construction, road maintenance, local government spending policies are studied. The current state of progress towards harmonisation of European standards is taken into account. The use of new materials in porous asphalt and "whisper" concrete, which require high PSV (Polished Stone Value) aggregates throughout rather than just the surface layer, will also increase the demand. The study records that high specification aggregates should be considered separately from general purpose aggregates in future mineral policies.


Objective
To explore the effect of vitamin D deficiency and falls on osteoporotic fracture (OPF) in patients with rheumatoid arthritis (RA).

Methods
A total of 852 patients with RA were recruited, anteroposterior and lateral X-rays examination of vertebral column were conducted for every patient. Serum 25-hydroxy vitamin D [25(OH)D] levels and bone mineral density (BMD) of all the vertebrae of lumbar were examined. Clinical and laboratory index of patients were recorded in details meanwhile. Data of 156 normal subjects during the same period were collected as the control group. Numerical data and categorical data comparisons were analyzed using t test,χ2 test, single factor analysis of variance test, linear correlation and Logistic regression analysis test.

Results
① The prevalence of vertebral OPF in RA was 16.1%(137/852). Compared to RA without OPF, patients with OPF had lower serum 25(OH)D levels [(14 ± 4) ng/ml vs (18 ± 7) ng/ml, t=2.898,P=0.004]. ② The occurrence rate of falls in RA patients was 19.7% (36/183). Patients with falls had lower serum 25(OH)D levels [(14±4) ng/ml vs (18±6) ng/ml,t=2.854,P=0.005]. ③ The prevalence of falls in RA with vertebral OPF was higher than that in RA without OPF (38.1% vs 14.2%,χ2=11.708,P=0.001). ④ Linear correlation analysis found that serum levels of 25(OH)D was positively correlated with total lumbar region BMD in RA patients. ⑤Logistic regression analysis revealed that age [OR=1.124,P=0.002, 95%CI: (1.045, 1.209)]and usage of glucocorticostroid (GC) [OR=6.724,P=0.031, 95%CI: (1.196, 37.813)] were the risk factors for occurrence of OPF in RA, while serum 25(OH) D level [OR=0.850,P=0.046, 95%CI: (0.725, 0.997)] was the protective factor.

Conclusion
Spinal OPF in patients with RA is clearly related with vitamin deficiency, falls and usage of GC.

A 39-year-old man with no notable past medical history was admitted with altered mental status. His brother had died at 14 years of age following a confusion episode of an unclear etiology, while his sister was in good health. At the time of admission, he was married with two healthy sons and worked full-time as an operations manager with no limitations. Two weeks prior to admission, following a sick contact, he developed a sore throat, and cough. Initially not responding to cefuroxime, the fever and sore throat resolved with dexamethasone with clindamycin, however, four days prior to admission, he became progressively tired, spending long hours in bed, "fuzzyheaded", confused with word finding difficulty and poor memory of recent events. At the local emergency room, he was found to be sleepier with paucity of movements prior to becoming unresponsive with no focal weakness. Initial work up including basic blood work, a head computed tomography (CT) scan, and lumbar puncture for cerebral spinal fluid analysis (CSF) were unrevealing. He was transferred to a tertiary center for further evaluation. At the tertiary institution, his vital signs were stable with a temperature of 36.1°C, blood pressure 130/40 mm Hg, heart rate 70 beats per minute, respiratory rate 12 breaths per minute and oxygen saturation of 100% on room air. He was not able to follow commands, produce spontaneous or provoked speech, although, had intermittent extremity movements, opening eyes unprompted and to noxious stimuli. There were no signs of meningeal irritation. Cranial nerves, motor and reflexes evaluation did not show any focal abnormalities. He was believed to have encephalopathy of an unclear etiology. His work up including, a complete blood count (CBC), comprehensive metabolic panel (CMP), toxicology, urinalysis showed elevated platelets 54110×9/L, ammonia 249 umol/L, relatively normal liver function tests alkaline phosphatase 59 U/L, aspartate transaminase (AST) 17 U/L, alanine transaminase (ALT) 41 U/L, AST/ALT ratio 0.4, albumin 4.3 g/dl, total bilirubin 0.7 mg/dl, and slightly elevated prothrombin time 14.4 seconds and international normalized ratio (INR) 1.4.

Are intellectual property rights and pharmaceutical companies truly guilty of aggravating the problem of access to drugs in poor countries? A review of the literature shows that the issue is complex and that it must take account of the different causes and actors involved in access to healthcare. We then examine how firms are becoming increasingly involved in new international strategies for health improvement. We conclude by stressing the need to clarify the objectives of these firms when they build partnerships with poor countries.


Objective To improve the resection rate of central type hepatoma. Method Under selective exclusion of hepatic blood flow and the use of caritational ultrasonic surgical aspiration (CUSA), hepatectomy of central hepatic segments was performed for liver tumors. Result There were 46 cases in this group. Preoperative hepatic function was Child A in 43 cases and Child B in 3 cases. Regional entire bloodstream was excluded ranging from 8 to 33 minutes in 39 cases, Intraoperative blood loss was 100 to 2400 ml,the average was 490 ml. Postoperative hepatic function recovery to Child A grade in 43 cases within one week, postoperative aacites developed in 3 cases, jaundice in 1 case, biliary fistula in 1 case, gastroplegia in 1 case. One patient died of myocardial infarction 3 days postoperatively. Thirty-five malignant cases were followed-up with a mean period of 9 months, one died of intraabdominal metastasis 10 months postoperatively, the other 34 cases was alive without recurrence. Conclusion Hepatic regional entire bloodstream exclusion is effective in the control of intraoperative blood loss ; Hypersound-emulsifying- attractor separates blood vessels and bile ducts in hepatic hilar region. The combination of these two techniques helps in the resection of central hepatic tumors.

Wear is an important index of performance of the friction. As the part——measure and control of MST-Ⅱ friction test-bed, the design of this system is based on the microcontroller-ATMEGA 168.In a test period, the microcontroller controls in file: clutch-touch, electric motor-start, clutch-separate, electric motor-stop, power-electro, power-broken, line and parameter-reveal and so on. Thereinto,the analog signals, exported by the pressure and the torque sensors, are sampled and calculated by the microcon-troller, thus the important calculating parameter of wear——the rub work will be got, and microcontroller controls the colorful touch-ing LCD to manifest the experiment parameter and draw the line graph of pressure-time and torque-time in each touch period.


Recently, a proposal of synthetic gauge field in reduced two-dimensional (2D) system from three-dimensional (3D) acoustic structure shows an analogue of the gapped Haldane model with fixed kz, and achieves the gapless Weyl semimetal phase in 3D momentum space. Here, extending this approach of synthetic gauge flux, we propose a reduced square lattice of acoustic resonators, which exhibits Dirac nodes with broken effective time-reversal symmetry. Protected by an additional hidden symmetry, these Dirac nodes with quantized values of topological charge are characterized by nonzero winding number and the finite structure exhibits flat edge modes that cannot be destroyed by perturbations.


Fifteen children, aged 7-18 years, were interviewed an average of five months after the murder of an older sibling. Although most showed significant symptoms of depression, anxiety, post-traumatic stress disorder, and psychosocial impairment, few had received any community or mental health system support or services for these symptoms. Specific problems and needs are identified, and implications for research and practice are discussed.


Cash waqf is a waqf fund in the form of a rupiah managed by the nazir to produce benefits in the form of marque alaih. This study aims to determine how big the factor of interest of the Muslim generation in cash waqf in West Nusa Tenggara Province (NTB). In this study, data was collected by distributing questionnaires by purposive sampling using the Cochran formula so that 100 respondents fulfilled the number of samples. Data analysis techniques using Partial Least Square-Structural Equation Modeling (PLS-SEM). The results showed that trust variables and subjective norms positively and significantly affected the interest in cash waqf in West Nusa Tenggara (NTB). Trust and subjective norm variables imply that the institution where waqf is collected can maintain trust in Wakif by making reports and documentation. At the same time, the promotion of socialisation and religiosity variables have a positive but insignificant effect. Moreover, the knowledge variable has a negative and little impact on the interest in cash waqf in West Nusa Tenggara Province.


The aim of this study was to examine brightness effect, which is the perceptual property 9 of visual stimuli, on brain responses obtained during visual processing of these stimuli. For this 10 purpose, brain responses of the brain to changes in brightness were explored comparatively using 11 different emotional images (pleasant, unpleasant and neutral) with different luminance levels. 12 Moreover, electroencephalography recordings from 12 different electrode sites of 31 healthy 13 participants were used. The power spectra obtained from the analysis of the recordings using short 14 time Fourier transform were analyzed, and a statistical analysis was performed on features extracted 15 from these power spectra. Statistical findings obtained from electrophysiological data were 16 compared with those obtained from behavioral data. The results showed that the brightness of 17 visual stimuli affected the power of brain responses depending on frequency, time and location. 18 According to the statistically verified findings, the distinctive effect of brightness occurred in the 19 parietal and occipital regions for all the three types of stimuli. Accordingly, the increase in the 20 brightness of pleasant and neutral images increased the average power of responses in the parietal 21 and occipital regions whereas the increase in the brightness of unpleasant images decreased the 22 average power of responses in these regions. However, the increase in brightness for all the three 23 types of stimuli reduced the average power of frontal and central region responses (except for 10024 300 ms time window for unpleasant stimuli). The statistical results obtained for unpleasant images 25 were found to be in accordance with the behavioral data. The results also revealed that the 26 brightness of visual stimuli could be represented by changing the activity power of the brain cortex. 27 The main contribution of this research was to comprehensively examine brightness effect on brain 28 activity for images with different emotional content and different frequency bands at different time 29 windows of visual processing for different brain regions. The findings emphasized that the 30 brightness of visual stimuli should be viewed as an important parameter in studies using emotional 31 image techniques such as image classification, emotion evaluation and neuro-marketing. 32


Missing or extra digital creases in individuals with or without certain syndromes and/or phenotypic changes are a source of continuous interest for geneticists, researchers and even forensic professionals. Still, with the advent of open access journals and improved accessibility to scientific literature, this topic seems to entice general public as well.


A search in the Cambridge Structural Database for NH-pyrazoles lacking other hydrogen-bond donor and acceptor sites, has identified 49 compounds that crystallize in 47 structures forming dimers (16), tetramers (13), trimers (8), hexamers (1) and catemers (10) using N-H···N hydrogen bonds. These structures have been classified in two classes (dimers and tetramers vs. trimers and catemers) using the accessible surface to an atom with good results. The method has been extended to new pyrazoles by means of theoretical calculations (B3LYP/6-31G*) of the geometry of the monomers. Aspects like the conformation of phenyl substituents, the additivity of substituent effects and the buttressing effect have been approached theoretically.

In this paper, we consider the recovery of piecewise sparse signals from incomplete noisy measurements via a greedy algorithm. Here piecewise sparse means that the signal can be approximated in certain domain with known number of nonzero entries in each piece/segment. This paper makes a two-fold contribution to this problem: 1) formulating a piecewise sparse model in the framework of compressed sensing and providing the theoretical analysis of corresponding sensing matrices; 2) developing a greedy algorithm called piecewise orthogonal matching pursuit (POMP) for the recovery of piecewise sparse signals. Experimental simulations verify the effectiveness of the proposed algorithms.

The damping smoke effect of the air curtain in atrium fire scenario of a distribution center is simulated by FDS. The altitude of the atrium is 32 m and there are 6 mechanical smoke exhaust exits on the roof. Total smoke exhaust quantity is 240 000 m3/h . The power of ignition source is 4 MW. The t2 growing fire locates beneath the atrium . After fire continues for 60 s, the mechanical smoke exhaust system and the air curtain system start up. The wind speed of the air curtain is 0, 0.5 m/s, 1 m/s, 2 m/s, 3 m/s and 4 m/s respectively. Results: When the wind speed is less than 1 m/s, the damping smoke effect is indefinite. When the wind speed is more than 3 m/s, the smoke exhaust effect of smoke exhaust system would encounter hamper. When the wind speed is 2 m/s, the air curtain can both develop the damping smoke effect, and stop the gathering of smoke in down layer. Conclusion: If the wind speed ofthe air curtain is reasonable, it may replace the fire resisting shutter in some degree.


We detected Mg(2+)-dependent, Ca(2+)-independent endonuclease activity in non-apoptotic myeloid leukemia cell nuclei using autodigestion method which cleaved the chromatin of the autologous leukemia cells to an oligonucleosomal length pattern. Similar endonuclease activity could be successfully recovered in the protein extracts of the human leukemia cell nuclei. The extracts consistently elicited characteristic DNA cleavage of another leukemia cell (KG-1) nuclei as the target, the enzyme activity of which had been inactivated. We propose that this method is a useful tool for the study of endonucleases involved in apoptosis.


The rapidly increasing need for information and communication triggers the high mobile data traffic. In addition, mobile data traffic has also increased along with the emergence of various types of services and new technologies. One of which is the presence of 5G (5th Generation) technology, which offers various advantages, and is expected to play an essential role as a trigger for transforming the role of mobile technology in society's lives.

The purpose of this study was to review the current language level of children from multi-cultural background and whether the language level of these children would be increased after participating in the `We Start Language Intervention Program`. The subjects were 30 36-75-month old children attending daycare centers in Ansan city, South Korea. The results showed that the receptive and expressive language levels of children from multi-cultural families were low compared to those of other children, and that their expressive language level was evaluated more negatively than their receptive language level. After participating in the `We Start Language Intervention Program`, language test scores, language age and language percentile rank were all increased. It was also found that the developmental language level of multi-cultural children increased, and that of the children that had a language delay or language disorder decreased.

A discussion of Lloyd's Tarner Lectures at Trinity College. The importance of Lloyd's previous scholarship is characterized and these sweeping, erudite lectures are placed in the context of that scholarship. In the broadest terms, the lectures are a call to culturally and historically comparative study of human reasoning. At their heart is a comparative history of scientific theorizing from the ancients through to modern science. Lloyd rejects the positivist picture, and the view of modern and ancient science as discontinuous; he urges scholars to undertake comparative work on the ancient sciences in different traditions. This critical notice evaluates Lloyd's view and raises several questions for further reflection.


Fluorescent-guided surgery using indocyanine green (ICG) is a rapidly expanding surgical technology, but its application in pediatrics remains unknown. Authors represent a descrip-tive analysis of the current applications of ICG in pediatric surgery based on a systematic bibliographical review on this topic. Material and methods used: the study searched articles in 3 major scientific databases (MEDLINE, PubMed and eLIBRARY.RU) published after 2000 for the keywords as follows: fluorescent-guided surgery, indocyanine green, ICG navigation, children. Two researchers independently reviewed the titles and abstracts of the primary search to avoid discrepancies. Results: initial database search yielded 762 titles. After the exclusion, 25 full-text publications were included in the generalization. Most studies were conducted in Italy (n=6) and the UK (n=6) followed in descending order by North America (n=5), Japan (n=4), Spain (n=2) and China (n=2). The distribution by time of publication was as follows: 2019 - 3, 2020 - 2; 2021 - 8; 2022 - 12. A systematic review includes 396 surgical interventions performed on pediatric patients using ICG. The most frequently performed surgical procedure in childhood was the Palomo varicocelectomy (66). This is followed by: abdominal tumors - 59, esophageal anastomosis - 53, renal cyst and duplication - 38, chest tumors - 37, ovarian tumors - 28, cholecystectomy - 26, kidney tumors - 24, liver tumors - 19, identification aortocoronary fistulas - 16. Most often, the drug was administered during the operation - 15 publications, 1 day before the operation - 9 publications, immediately be-fore the operation - a single publication. The methods of administration were distributed as follows: intravenous - 21, intraluminal - 2, intraorgan - 1, intratesticular - 1. Dosing of the drug depends on the method of application of ICG and the area of its application. Most of-ten, the drug was used intravenously in dosages from 0.1 to 0.75 mg/kg. For tumors, in-creased doses of the drug were used from 1.5 mg/kg for tumors of the abdominal cavity to 2 mg/kg for hyperinsulinism. Insufficient visualization of anatomical objects was only re-ported in 3 cases. Information about the side effects of the introduction of ICG in the body of a child is scarce and is represented by only 2 mentions of cardiac arrest and desaturation, which both ended safely. Conclusion: current trends demonstrate that fluorescent-guided surgery has become commercially available and is increasingly being used among pediatric surgeons to treat a wide range of diseases, including hepatobiliary surgery, oncology, urolo-gy, cardiac and vascular surgery, and is also used to assess blood flow in operated organs of a patient.

form. But we find that this obstacle, this opposition between power and Power, between metaphysics and history, does not block Spinoza's in quiry. In fact, as Negri follows the development of Spinoza's project to its mature phase, he discovers two strategies for destroying this opposition. To gether, they form a sort of chiasmus: One strategy progresses from power to Power, from metaphysics toward politics and history; the other moves in the opposite direction, from Power to power, from politics and history toward metaphysics. The recognition of the ontological density and the political centrality of Spinoza's metaphysical conception of power is perhaps Negri's most impor tant contribution. The theoretical construction of power, a long process of the accumulation of conceptual relations, extends throughout Spinoza's work. It begins with the human essence, conatus, or "striving," and pro ceeds through desire and imagination to arrive at an image of the power to think and act as a complex productive force. Yet we cannot be satisfied with any idea of power that remains merely an individual force or impulse, be cause power is always organizing itself in a collective dimension. The Theologico-Political Treatise and parts III and N of the Ethics are central texts in this regard, because they develop an analysis of the real, immediate, and associative movements of human power, driven by imagination, love, and desire. It is through this organizational project of power that the meta physical discussion of human nature enters the domain of ethics and poli tics, Negri highlights two Spinozian concepts to bring out this organiza tional aspect of power: the multitude and constitution. ¥.u[titude is the term Spinoza uses to describe the collective social subject that Is unified inasmuch as it manifests common desires through common soCial behavior. Through the passion and intelligence of the multitude, power is constantly engaged in inventing new social relations. The multitude, the protagonist of Spinoza's democratic vision, creates a social authority through the process of consti tution, a process whereby social norms and right are constructed from the base of society through a logic of immediate, collective, and associative re lations. In the process of constitution the metaphysics of power becomes an ethics, an ethics of collective passions, of the imagination and desire of the multitude. This analysis of power brings us from metaphysics to politics and thereby prepares the ground for addressing the historical dimension, the problem of the real existence and eminence of Power. In the Political Treatise Spinoza develops a logic for evalua.�ing political forms, and Negri shows us how this logic sets in motion a tendency that n10\'es from Power to power on the basis of th,e constitutive power of the multitude. Spinoza starts from his present point in history by considering what would be the best constitution of a monarchical government. With his developed conception of power and right as a foundation, Spinoza argues xvi Translator's Foreword that from the point of view of peace and freedom the best monarchy is one in which the supreme Power, the monarch, is moderated by the constitutive power of the multitude. In other words, monarchy is a limited form to the extent that the supreme Power is not freely constituted by the multitude. Spinoza turns to aristocratic government as the next step in the progression from Power to power. According to Spinoza's logic, aristocracy is a less lim ited form of government to the extent that the supreme Power, in the form of a council, is more fully constituted by the multitude. Democratic govern ment is the final point of this process, but unfortunately Spinoza died before completing this section. The logic, however, is clear. Democracy is to be the absolute, unlimited form of government, because in it the supre�ePower!S fully consti�l1t.!r4 by the power of the multitude: Spinoza's democracy is to�oe ariimated by a constituent Power, a dynamic form of popular authority.4 With this progression from monarchy through aristocracy to democracy, Spinoza moves from history to metaphysics, from Power to power. In effect, democracy is a return to the plane of the Ethics: Power (potentia) does not exist in Spinoza's democracy except to the extent that it is a constituent Power, completely and freely constituted by the power of the multitude. In a certain sense, then, the trajectory we have sketched here of the relationship between Power and power has come full circle to its point of departure, but in the process it has gained both a metaphysical density and the corporeality of concrete political determinations. If the Ethics reduces the distinction and subordinates Power to power in the idealistic terms of its utopian vision, the Political Treatise poses the real tendency toward a future reduction of the .distinction, when a democratic Power would be completely constitute(fby the power of the multitude. In this image of democracy Spinoza's vision is at least as alive today as it was in his own time. Here we can see the tendency he describes as our own future. Spinoza is the anomaly. The fact that Spinoza, atheist and damned, does not end up behind bars or burned at the stake, like other revolutionary innova tors of the sixteenth and seventeenth centuries, can only mean that his meta physics effectively represents the pole of an antagonistic relationship of force that is already solidly established: The development of productive forces and relations of production in seventeenth-century Holland already compre hends the tendency toward an antagonistic future. Within this frame, then, Spinoza's materialist metaphysics is the potent anomaly of the century: not a vanquished or marginal anomaly but, rather, a!l anomaly of victorious materialism, of the ontology of a being that always moves forward and that by constituting itself poses the ideal possibility for revolutionizing the world. · ·· · -there are three reasons why it is useful to study Spinoza's thought, each of them not only positive but also problematic. In other words, Spinoza not only poses and resolves several problems of and in his own time; the very form of the Spinozian solution comprehends a progressive problematic that reaches our time and inserts itself into our philosophical horizon. The three problematic reasons that make studying Spinoza's thought important are the following. First: Spinc:>Za founds .Modern materialism in its highest form, determin ing the horizons of both Modern and contemporary philosophical specula tion within an immanent and given philosophy of being and an atheism defined as the negation of every presupposed ordering of eitherthe


Onset of psoriasis may occur at any age. Early negative experiences often influence personality development, and may lead to physical disease, anxiety and depression in adulthood. Knowledge about onset of psoriasis and psychopathology is limited.


Power train of hybrid electric vehicle (HEV) equipped with automatic mechanical transmission (AMT) is made up of engine, electric motor, batteries and propulsion system. Shift rule can not be worked out with the same way of conventional AMT vehicle. Considering performance of engine, ISG motor and state of charge (SOC) power distribution strategy and shift rule of mild HEVs equipped with AMT were put forward based on vehicle in the case that vehicle was driven by both engine and motor to take best advantage of fuel. Simulation results indicate that fuel economy performance of mild HEVs equipped with AMT is improved by using the new power distribution strategy and shift rule.


It is often necessary to establish construction zones on roadways for pavement and bridge repair and rehabilitation activities. A construction zone reduces the number of lanes available for traveling vehicles and therefore forms a bottleneck section for traffic flow. The ability of dynamically predicting traffic flow rates with real-time data is essential for both highway engineers and construction contractors. For highway engineers, the predicted values of traffic flow rates could be utilized to maintain smooth traffic flows at construction zones. It would enable them to apply traffic control measures to prevent traffic congestion at construction zones rather than to deal with traffic problems after traffic congestion already occurred. For contractors, knowing the future traffic conditions around construction zones would be great advantageous in scheduling construction activities and equipment movements. It was found in this study that using the Kalman predictor in combination with the first-order autoregressive time series provided satisfactory dynamic predictions of construction zone traffic flow. A prediction of traffic flow at a construction zone also constitutes a prediction of traffic congestion if the traffic capacity of the construction zone is known. If the predicted traffic flow rate is equal to or greater than the traffic capacity, then traffic congestion is expected in the coming time period and appropriate traffic control actions can be taken to prevent the traffic congestion.


ABSTRACT Using the work of the peaceably radical seventeenth century writer John Archer as a case study, this paper explores Baptist attitudes towards violence. Though he was not a Baptist, it is argued that Archer's work shaped the Fifth Monarchist movement, and the associated seventeenth century radical Baptist tradition. Given that Archer's vision for human non-violence was predicated upon a belief that 'it is God alone who will destroy the enemies of the saints', the question is raised as to whether his theological approach presented a 'missed opportunity' for seventeenth century Baptists to embrace a thoroughgoing nonviolent radicalism. Finally, consideration is given to divine judgment as a motivation for human violent action and questions are raised for those seeking to articulate a manifesto for Baptist non-violence in later generations.


The experimental investigation of Heavy Ion reactions at Fermi energies requires an accurate measurement of observables, such as linear momentum and energy of the detected particles. In order to address this problem, dedicated and flexible correlator arrays are useful tools to be coupled with 4 π detectors. One of these arrays is FARCOS, presently under construction at the INFN Sezione di Catania and Laboratori Nazionali del Sud (LNS).


Objective  The presence of both the GH secretagogue (GHS) receptor and ghrelin in the pancreas indicates an involvement of this hormone in glucose metabolism. Ghrelin secretion is increased by fasting and energy restriction, decreased by food intake, glucose load, insulin and somatostatin in normal adults; however, food intake is not able to inhibit circulating ghrelin levels in children, suggesting that the profile of ghrelin secretion in children is different from that in adults. Moreover, how ghrelin secretion is regulated in childhood as a function of fat mass is still unclear.


During the changing period of the social reframe,the national social framework and economical development are changing intensively.The over-passed social family framework disaggregated and the system of social ethic,especially family social ethic,is facing the unprecedented impact.So it is imperative to rebuild the family social ethic in the socialistic marketing economic.Above all,we have to finish the following three tasks: establishing fealty-kindliness concept suit with modern social relations;trying for the appropriate spouse relation in up-to-date family;establishing the fair and companionate ethical morality to cultivate modern personality.


The aim of this research was to use a benign technique for the sterilization of ultra-high molecular weight polyethylene (UHMWPE), which is broadly used in artificial joints and other medical implants. Current sterilizations methods such as gamma irradiation, ethylene oxide gas, and gas plasma can damage the polymer, thus reducing its service life, as well as create harmful byproducts. Supercritical carbon dioxide (SC) CO2 sterilization has the potential to greatly reduce both polymer degradation and negative environmental impacts. The former extends the life of the implant and the latter decreases waste disposal costs and minimizes risk to sterilization workers. The feasibility of using SC CO2 modified with additives such as ethanol, water and hydrogen peroxide was assessed for the sterilization of UHMWPE. The operating conditions and the amount of modifiers were optimized to achieve a complete inactivation of bacteria (spores included) and fungi. When equal volumes of all modifiers were added to CO2 at 37oC and 170 bar so that their total mole fraction was ≥ 4.1E-03, complete inactivation of all microorganisms was achieved within 2 hours. The physio-chemical properties of the polymer were tested for untreated, as well as treated samples. An Instron measured the mechanical strength and elongation of the polymer, and Fourier Transform Infrared (FTIR) spectroscopy was used to measure the level of oxidation of the polymer to evaluate polymer chain damage. Both the physical and chemical properties of the polymer were unchanged after the SC CO2 sterilization technique. This research has shown that it is possible to sterilize medical grade polymer, under relatively safe conditions, without affecting its physio-chemical properties. _____________________________________________________________________ i Acknowledgements I would like to thank The Ohio State University and the William G.

Setting of the use functions and the corresponding operation time can be finished by rotating the knob for one circle, and operation procedures of household electric appliances are greatly simplified.


The propagation of linear, as well as nonlinear, dust-acoustic waves in inhomogeneous dusty plasmas consisting of electrons, ions, and charged dust particles is investigated. It is shown that the amplitude of the dust-acoustic waves is affected by the presence of the dust density inhomogeneity. Amplitudes of the linear and nonlinear dust-acoustic waves decrease (increase) as the waves propagate in the direction of increasing (decreasing) density. The wave amplitude is inversely proportional to the square root of the dust particle's density for the linear dust-acoustic waves. In the nonlinear case, to the lowest order and for the cold dust species, the wave amplitude is found to be directly proportional to nd0−1/4. Various special cases are explicitly considered, and comparison with the corresponding results for the usual two-component electron-ion plasmas is also carried out.


The Nigerian housing project setting has been marred with challenges which have continuously led to project under-performance and failure. Corporate social responsibility (CSR) is presented as a strategy to mitigate the challenges. CSR which deals with housing project firms' responsibilities in service delivery towards shareholders, stakeholders and society comprises a landscape of theories. The absence of CSR application towards solving housing project life cycle challenges presented a gap which informed the study. Variables are presented in a suitable and explored framework with a view to examining the potentials of CSR as a panacea to the challenges. This study presents stakeholder and ethical theories as the underpinning theories for the application of CSR in the management of housing projects along the project life cycle phases. Stakeholder theory states that firms' owe a responsibility to a wider group of stakeholders, other than just shareholders. Ethical theory of CSR applies to housing projects as ethics help to guide the practice of various stakeholders involved in the process of housing project management. Methodology used was a review of documented evidence from related literature. This study found that CSR application in Nigerian housing projects, although rudimentary has yielded positives when implemented. Proper CSR application in housing projects has the capacity to mitigate housing project challenges across each project life cycle phase. This study also recommends the proposition of CSR application in effective housing project management as a standard being a panacea to existing challenges.

Testing the standard cosmological model ($\Lambda$CDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models by linking observational properties of galaxies at small scales (low mass, low velocity) to low-mass dark matter halos. However, the observed kinematics of these galaxies do not align with the kinematics of the dark matter halos predicted to host them, obscuring our understanding of the low-mass end of the galaxy-halo connection. We use deep HI observations of low-mass galaxies at high spectral resolution in combination with cosmological simulations of dwarf galaxies to better understand the connection between dwarf galaxy kinematics and low-mass halos. Specifically, we use HI line widths to directly compare to the maximum velocities in a dark matter halo, and find that each deeper measurement approaches the expected one-to-one relationship between the observed kinematics and the predicted kinematics in $\Lambda$CDM. We also measure baryonic masses and place these on the Baryonic Tully-Fisher relation (BTFR). Again, our deepest measurements approach the theoretical predictions for the low-mass end of this relation, a significant improvement on similar measurements based on line widths measured at 50\% and 20\% of the peak. Our data also hints at the rollover in the BTFR predicted by hydrodynamical simulations of $\Lambda$CDM for low-mass galaxies.


A chemical two-step approach based on solvothermal technique has been adopted to synthesize the reduced graphene oxide (rGO)/Fe2O3 hybrid materials. The rGO was prepurified by acidic treatment, followed by sensitization to attach the desired functional groups. The structural, compositional, morphological and magnetic analyzes of the prepared samples were carried out using various characterization techniques. The fabricated rGO/Fe2O3 heterostructures were confirmed by X-ray diffraction analysis and Fourier transform infrared spectroscopy. Raman spectroscopy evidenced the fabrication of multilayer graphene and scanning electron microscopy was carried out to study the morphology of the prepared samples. The average particle size of Fe2O3 nanoparticles (NPs) loaded on rGO was found to be ∼20 nm, as was observed during transmission electron microscopy. Thermogravimetric analysis of rGO/Fe2O3 hybrid structures was performed to investigate their thermal behaviors. It was evidenced that the incorporation of Fe2O3 NPs into rGO enhanced its thermal stability. Vibrating sample magnetometry showed that ferromagnetic character was induced in rGO due to involvement of Fe2O3 NPs. The rGO/Fe2O3 hybrid structures can be considered as a competent material for fabrication of various magnetic devices.


A Run II D0 Inter Cryostat Detector tile array will be composed of 16 identical modules. Each module contains 12 optically isolated scintillating tile elements, each with dimension of 0.1 x 0.1 in {eta} and {phi} in the pseudora-pidity region from 1.1 to 1.4. The 12 tiles in a module are formed by routing grooves in a single piece of scintillator - optical isolation is achieved by fill-ing the grooves with a white re ective epoxy. The procedure for filling these isolation grooves is described here.
