Seeds of Lupinus angustifolius were given X-ray doses of 2.5, 5, 10, and 20 kr at each of 12 moisture contents ranging from 6.1 to 18.1 % (wet weight basis). Various measures of injury were recorded in the X1 generation, and the types and rates of mutations in the X2. At moisture contents below 16%, total mutation rates were closely correlated with X1 injury. Injury and mutation rate decreased with increasing moisture up to 11–12% moisture, and thereafter remained at a constant minimum up to 16%. Between 16 and 18% moisture there was again an increase in X1 injury, but not in mutation rate. Between 6 and 12 % moisture, a linear relationship was found between moisture content and the logarithm of the dose required to cause a given level of injury or mutation. A possible mechanism for such a pattern of protection is discussed. Lethal mutations increased as a proportion of all mutations as dose and mutation rate increased. There were also proportionately more lethals at high moisture contents than in lower moisture treatments giving the same mutation rates. It is concluded that lethal and seedling chlorophyll-deficient mutations could be misleading when used as indicators of total and viable mutation rates, and that, contrary to the conclusions of some previous authors, no advantage is likely to be gained in practical breeding work from irradiating at high seed moisture contents.

The exploration of inexpensive and stable heterogeneous catalysts for C–S coupling reactions remains a challenging issue. Herein, we successfully prepared a new biomass-derived copper catalyst and applied it to the selective C(sp3)–H-directed sulfonylation of ketone hydrazones with commercial sodium sulfinates. The catalyst was characterized using different spectroscopic and microscopic techniques. Importantly, the prepared biomass-supported Cu catalyst catalyzed the C–S coupling reaction with considerably high activity. A variety of aryl and alkyl sulfinates were converted to the corresponding sulfones with good yields. In particular, the heterogeneous catalyst could be recovered easily after the synthesis and consecutively used at least five times with no appreciable decrease in the catalytic activity. Lastly, the copper catalyst is expected to have further applications in organic reactions catalyzed by Cu/CuO2.

ObjectiveTo identify independent risk factors of pulmonary thromboembolism and to estimate the risk of each factor.MethodsSeventy-one patients with pulmonary thromboembolism and 71 sex-and age-matched patients and healthy controls were recruited in this study.The diagnosis was confirmed by lung ventilation /perfusion scan and /or spiral CT as well as medical history.DVT was documented using ultrasonography or CT venography.Correlation risk factors mentioned in literatures were recorded in details and some factors were controlled.After fasting for 12 hours,all the subjects underwent blood routine,triglycerides,cholesterol,AT-Ⅲ,fibrinogen plasminogen.SPSS was used for t-test,χ~2-test and Logistic regression analysis.(ResultsIndependent) risk factors for VTE included deep venous thrombosis(OR 44.427,95% CI 10.105-195.317,P0.05),operation(OR 3.407,95% CI 1.042-11.136,P0.05),fibrinogen(OR 1.717,95% CI 1.250-3.569,P0.05),cholesterol(OR 1.678,95% CI 1.287-3.672,P0.05),plasminogen(OR 1.022,95% CI 1.000-1.121,P0.05) and smoking index(OR 1.003,95% CI 1.001-1.006,P0.05).ConclusionDeep vinous thrombosis,operation,fibrinogen,cholesterol,plasminogen,and smoking are independent and important risk factors for VTE.


Production test of parametric specifications is a significant contributor to the overall cost of build for analog and mixed-signal products. Data converters (ADCs and DACs) in particular are critical components of integrated circuits used in control/actuation and sensing applications. If left un-optimized, their production test time often dominates the overall system-on-chip (SoC) test time. In this paper, we specifically focus on static linearity test of DACs and propose architecture-aware test methods that are combined with best-in-class fast linearity test concepts in the literature to minimize test time without compromising test quality. The proposed methods exploit the hypothesis that the number of device errors which contribute to linearity errors can be captured by a significantly fewer number of variables than the number of codes at which linearity needs to be tested. We introduce a new time and memory efficient method called Extrapolated Reconstruction (ER) to calculate DAC INL and DNL, based on the segmented model introduced in uSMILE. We also demonstrate that since the segmented model techniques do not account for interpolation, they are not suitable for interpolated DACs. We thus develop an interpolated segmented model and enhance both uSMILE and ER to obtain two new methods that provide correct estimations for interpolated DACs. A linearity test time reduction of 15x-20x was seen in actual silicon measurement results for multiple 12-bit DACs and >100x was seen in simulation case studies for many 16-bit DACs.


In response to a highly competitive business environment, organizations need to use effective selection tools to identify potential talented employees. High structured interviews (HSIs) have been shown to have high criterion-related validity and reliability but remain much less popular than low structured interviews (LSIs). As the issue of interviewer reaction toward HSI remains largely unexamined, this study intends to examine how interviewer-related factors (cognitive style and needs for power) and situational factors (job complexity and organizational interview norms) jointly influence interviewer reactions toward HSI. Using a sample of 292 interviewers from 33 firms in Taiwan, we found that analytic interviewers and those who worked in firms with higher organizational interview norms reacted more positively toward HSI. Furthermore, analytic interviewers reacted more positively toward HSI for interview positions with higher job complexity. Unexpectedly, in organizations with higher interview norms, interviewers' needs for power were positively related to their reactions toward HSI. Practically, our findings shed light on ways in which organizations could increase interviewers' willingness to conduct HSI so as to ensure the greatest potential of HSI in the process of personnel selection.


The turn from sociology of scientific knowledge to technology studies happened in 1980s.The new approach about the social construction of technology outbreak the lineage model of the technology,and make an emphasis on the multimode and nonlinear character in the shaping of technology.Meanwhile,it stressed on that the success of technology lays more the success of the system than the success of technology itself.It can be illustrated from the essay that social constructivism can be used in the technology studies,and the symmetry principle within the SSK also can be extended into technology studies.

The aim of the study is to compare, in coronary artery disease patients, physical activity (PA) assessed with the Dijon Physical Activity Questionnaire (DPAQ) and the true PA objectively measured using an accelerometer. Seventy patients wore an accelerometer (MyWellness Key actimeter) throughout 1 week after a cardiac rehabilitation program that included therapeutic education about regular PA. Patients completed the DPAQ at the end of the week. The mean weekly active energy expenditure was 619.9±374.6 kcal, and the mean DPAQ score was 21.3±3.1/30 points. There were low but significant correlations between total active energy expenditure and the DPAQ score (&rgr;=0.4, P=0.009). There were no correlations between peak power output and total DPAQ score. The DPAQ significantly correlates with objective measures given by the MyWellness Key actimeter. The choice between these tools relies on the clinician's appreciation, taking into account patients' characteristics and goals as well as the cost of the method and availability of the tool.


Introduction Multiparity has been associated with increased risk of cardiovascular disease (CVD). Inflammation may be a mechanism linking parity to CVD. We investigated the association between parity and later-life markers of inflammation. Methods We studied 3,454 female MESA participants aged 45–84, free of CVD, who had data on parity and inflammatory markers. Parity was categorized as 0 (reference), 1–2, 3–4, or ≥5. Linear regression was used to evaluate the association between parity and natural log-transformed levels of fibrinogen, D-dimer, GlycA, high sensitivity C-reactive protein (hsCRP), and interleukin-6 (IL-6). Results Mean age was 62 ± 10 years. The proportion of women with nulliparity, 1–2, 3–4, and ≥5 live births were 18, 39, 29, and 14%, respectively. There was no association between parity and fibrinogen. Women with grand multiparity (≥5 live births) had 28, 10, and 18% higher levels of hsCRP, IL-6 and D-dimer, respectively, compared to nulliparous women, after adjustment for demographic factors. After additional adjustment for CVD risk factors, women with 1–2 and 3–4 live births had higher hsCRP and women with 1–2 live births had higher GlycA. Conclusion In this diverse cohort of middle-to-older aged women, we found that higher parity was associated with some inflammatory markers; however, these associations were largely attenuated after adjustment for CVD risk factors. There was no clear dose-response relationship between parity and these inflammatory markers. Future studies are needed to evaluate how inflammation may influence the link between parity and CVD and whether healthy lifestyle/pharmacotherapies targeting inflammation can reduce CVD risk among multiparous women.

The purpose of this study is to reveal several problems related to the application of modern management in the management of Savings and Loans Cooperatives (KSP), especially in the KSP Puskopdit Bali Artha Guna (BAG). Puskopdit Bali Artha Guna is a secondary KSP which until the end of 2018 has 20 primary cooperative members with 58,520 individual members spread across Bali. Cooperatives as a form of business entity engaged in the economy have a management structure that is somewhat different from other business entities. To achieve the goals of cooperatives, it is necessary to apply a good management system, namely implementing management functions. Some of the problems described in the discussion include 1) in what ways the development of modern management has been carried out at KSP Puskopdit Bali Artha Guna; 2) how is the implementation of modern management practices in cooperatives in facing today's business competition; 3) what benefits can be generated for the community, especially cooperative members in Bali. The method used in this research is descriptive qualitative with the method of collecting data through literature studies and in-depth interviews. In general, members of the Puskopdit Bali Artha Guna cooperative have digitized and implemented modern management in their operational systems to remain competitive in the millennial era who are familiar with technology, so that they are able to compete with other financial institutions.


Read-type oscillations were observed in the low-current region, as well as uniform avalanche-type oscillations in the high-current region from the same silicon p-v-n diodes designed for varactors. The existence of the peak in electric field is considered as a reason for the former oscillation. Effects of the series resistance of the diode were experimentally clarified.

Abstract This article puts forward the argument that urban governance in metropolises in the global South has entered a territorial moment. There is a subtle shift of emphasis underway in many Southern metropolises as municipal governments increasingly focus on transforming urban space rather than 'improving' populations. This shift away from Foucauldian disciplinary tactics—i.e. fixing people in place, classifying them into populations and acting upon them—is driven by political economic circumstances. Many of these cities have abundant reserves of capital and labor but they remain intractably disconnected; the former is invested in real estate and infrastructure, while a large number of urban residents struggle to sell their labor power for a wage. In this context municipal governments seek to manage the transformation of urban space, the urban governance strategies for which are presented here in a typology ranging from modest efforts to control places that were hitherto beyond the reach of the state through to the wholesale creation of new cities. Ultimately this article demonstrates that any attempt to 'reload' urban studies must focus on the governance of territory—i.e. the reconfiguration of power and place—in metropolises at the frontier of the urban revolution.


Electromigration (EM) is a traditional reliability concern, aggravated recently due to intense shrinking of wire sizes and the increase in the number of interconnections on a system-on-chip (SoC). Thereby, it challenges the state-of-the-art in design, physics, process and CAD processes. To that regard, we propose a new EM check method named Via Node Vector method. The conventional EM check ignores the lead EM interaction in circuits and only checks the local current densities. The new method addresses the EM interactions and checks the EM reliability at the lead connection sites (called via node). It converts the electrical current density of each lead into an effective current density for the EM interaction consideration. For this, we introduce three new factors: length (FL), width (FW), and interaction (FB). The effective current density divergence at a via node is derived as an addition of the effective current densities of all the interacting leads, which is a close proxy to represent the physical atomic flux divergence at the via node. This divergence at a via node can then be readily compared with the technology EM spec. The proposed method is successfully applied to 28nm node IPs and shows up to ∼4X higher safe operating frequency than the conventional method allows. Additionally, it successfully identifies risky sites missed by conventional check. The Via Node Vector Method will provide higher performance with reliability in designing advanced digital and analog circuits.


ABSTRACT Dissolved silicate (DSi) in coastal waters plays a crucial role in phytoplankton growth particularly diatom. This study aimed to determine DSi concentration seasonally in waters of the western coast of South Sulawesi in relation to coastal water quality indicator. Water, chlorophyll-a, and diatom samples were collected from the coastal areas of the Tallo-Makassar, Maros, and Pangkep, in April 2013 (transitional season), June 2013 (dry season), and February 2014 (wet season). Factorial analysis of variance was used to identify significant seasonal and temporal variations, and linear regression was used to test the relationship of chlorophyll-a and diatom abundance to DSi concentrations. The results showed that the DSi concentration was higher in the wet season of 35.2-85.2 µM than in the other seasons (transitional season: 10.8-68.4 µM, dry season: 9.59-24.1 µM). The abundance of diatoms during the transitional season reached ~9.7x107 cell/m3 in the Pangkep river, 2.3x107 cell/m3 in the Tallo river, and 1.3 x 107 cell/m3 in the Maros river. Chaetoceros, Nitzschia, and Rhizosolenia dominated the diatom composition. The mean concentration of chlorophyll-a in the Makassar coastal waters was 4.52±4.66 mg/m3, while in the Maros and Pangkep waters of 1.40±1.06, and 2.72±1.94  mg/m3, respectively. There was no strong linear corelation between DSi and diatom abundances, nor chlorophyll-a. These results suggested that DSi become a non-limiting factor for the diatom growth and potentially reduce the water quality via eutrophication and diatom blooms. Keywords: dissolved silicate, diatom, chlorophyll-a, coastal waters, South Sulawesi


The development of high-efficiency visible-light-active photocatalysts to eliminate emerging contaminants is of great significance for environmental remediation and personal safety.

In this work, BiOBr and two oxygen-rich bismuth oxybromide (Bi4O5Br2-EG and Bi4O5Br2-H2O) were synthesized by solvothermal method through the reaction of Bi3+ and Br- in different reaction medium (ethylene glycol or
water) and alkali conditions. The composition, structure, morphology, light absorption, surface area, and surface feature of
the synthetic bismuth oxybromides were systematically characterized. Due to the presence of ethylene glycol and OH-, the
Bi4O5Br2-EG preferentially exposes the 010 facets. The formation of hierarchical flower-like structures of Bi4O5Br2-
EG can be elucidated by the dissolution-recrystallization-growth mechanism. The bismuth oxybromides were then used for
photocatalytic degradation of methyl parahydroxybenzoate (a commonly used preservative but exposes endocrine disrupting
activity) under visible-light irradiation.

Since Bi4O5Br2-EG has a satisfactory band structure (bandgap energy ~2.61 eV, valence band potential +2.45 V),
high surface area (49.0 m2g-1), and negatively charged surface, its photocatalytic removal efficiency of MPHB is 46.5 and
41.2 times that of BiOBr and Bi4O5Br2-H2O, respectively. During the photodegradation reaction, holes and superoxide
radicals were recognized as the key reactive oxide species.

In addition, the as-synthesized Bi4O5Br2-EG is stable and easy to reuse, suggesting it is a potential candidate
for wastewater treatment.


This paper explores how shame is constructed in working-class "coloured" men's talk about their violence against women partners in Cape Town, South Africa. It examines how men who are violent toward their partners attempt to dissociate from their shamed identities and their perpetration of violence at the intersection of their gender, race and class identities, and how these processes allow men to produce subjectivities as "respectable coloured" men. Ten individual interviews were conducted with men who had perpetrated violence against their partner(s) residing in a predominantly working-class "coloured" community on the peripheries of Cape Town, South Africa. A Foucauldian discourse analysis tracks the complicated processes followed by men in dissociating from shamed subjectivities towards ones that encompass pride. The men talk about the battle for subjectivity in their pursuit for a "respectable", "good" masculinity, which is commended in specific pro-feminist spaces while being reportedly questioned or denounced by their fellow community members. The article concludes by considering the usefulness of shame in this sample of South African "coloured" men, and its capacity to mobilise men towards a pro-feminist politics.


Proximate composition and concentration of macro (Ca, K, Na and Mg) and trace elements (Mn, Cu, Zn and Fe) of five different Small Indigenous Fishes of Manipur viz Devario acquipinnatus, Glossogobius giuris, Hypsibarbus myitkyinae, Puntius chola and Tariqilabeo burmanicus was analyzed. Significantly higher (P<0.05) moisture (76.21±1.11) was recorded in G. giuris. Concentration of protein (21.00±0.00) was found highest in D. acquipinnatus. In T. burmanicus, significantly higher lipid (10.76±0.03) and ash (4.00±0.12) were recorded among the small fishes studied. Macro and trace mineral elements were recorded in all the fishes. Results from the analysis revealed that Ca, Mg and K were 2244.0±3.77 mg/100g, 125.8±1.09 mg/100g and 149.8±1.1 mg/100g respectively which shows significantly (P<0.05) higher in G. giuris among the fish species studied. Significantly higher (P<0.05) Na (102.4±1.7 mg/100g), Mn (1.26±0.04 mg/100g) and Zn (1.77±0.013 mg/100g) respectively were recorded in P. chola Higher concentration of Cu (0.35±0.007 mg/100g) and Fe (25.3±0.36 mg/100g) were observed highest in T. burmanicus and D. acquipinnatus respectively. From the above study, it was revealed that Small Indigenous Fishes are good sources of essential mineral elements which are indispensable for the maintenance of human health and various physiological abnormalities of the human body. Thus consumption and conservation of small fishes should be encouraged. © 2018 The Authors. Published by JFLS.

An investigation of student ability to use different forms of representation in applying basic principles of the refraction of light to make image predictions. Paper presented in the Discipline Based Education Research - A View from Physics Invited Symposium.


PURPOSE: The aim of this study was to evaluate the role of 25-gauge transconjuntival sutureless vitrectomy (TSV) in patients with persistent vitreous floaters who underwent multifocal intraocular lens (IOL) implantation. METHODS: Fourteen eyes of 11 patients with multifocal IOL implant associated with vitreous opacities that underwent 25-gauge vitrectomy were prospectively analyzed. Information collected included near (UCNVA) and distance uncorrected visual acuity (UCDVA), best corrected distance visual acuity (BCDVA), and the spherical equivalent (SE) before and 3 months after vitrectomy. Patients were questioned about surgery satisfaction and visual improvement after vitrectomy. RESULTS: Three months after 25-gauge TSV the mean visual acuities were: UCDVA, 0,10 ± 0,14; BCDVA, 0,02 ± 0,08; UCNVA, 0,00 ± 0,0; SE, +0,16 ± 0,34. Thirteen eyes (92.9%) had a UCDVA of 0.5 (20/40) or better, and 11 (78.5%) achieved a UCDVA of 0.8 (20/25) or better. Ten (90.9%) patients demonstrated satisfaction with surgery, and floaters have gone away in thirteen eyes (92.8%), while one patient expressed no satisfaction with her postoperative visual acuity because of the cystoid macular edema that occurred. CONCLUSION: 25-gauge TSV was a safe and accurate option for patients with multifocal lens and visual disturbing vitreous floaters providing subjective improvement of symptoms.


In this paper, the boundary layer analysis of three-dimensional Prandtl nanofluid flow over a convectively heated sheet in a porous material is addressed. Nonlinear radiation and high-order chemical reaction analysis are featured in this work. Nonlinear differential equations representing flow expressions are numerically solved by shooting technique. Features of Brownian motion and thermophoresis accounting for nanoparticle diffusion are taken into account. Then, a complete discussion of the influences of the flow regime on several thermofluidic parameters is presented. The outcome of the present study is that velocity field lines are grown due to the strengthening of Prandtl fluid numbers β 1 and β 2 while a reverse trend takes place for temperature profile. Furthermore, it is shown that when the magnetic strength is improved, the skin friction coefficient and heat transfer rate triggers considerable evolution. The obtained results of this model closely match with those available in the literature as a limiting situation.


With the development of nanometer semiconductor laser technology, due to the wide range of photobiological regulation and non-invasive advantages, it is widely used in clinical research, including reducing pain, accelerating wound healing, nerve injury repair and regeneration. Increase tissue blood flow, improve anxiety and depression, and treat Parkinson's and retinal diseases. However, in many studies, the role of photobiological regulation is still controversial. There are two main problems, one is that the mechanism of photo biological regulation is not fully understood, and the other is that the specific parameters are not uniform in different treatments, such as wavelength density, power density, pulse, treatment timing, and number of treatments. In this paper, through the second question, the parameters of low-energy near-infrared light (810 nm semiconductor laser) in the treatment of fundus diseases are the main research objects. Based on understanding the parameters of low-energy lasers, cyan blue is irradiated with different energy near-infrared light. Data analysis of the actual energy obtained after the retina of the rabbit and observation and research on the cell morphology of each layer of the retina, to obtain relatively safe treatment parameters for the retina, provide theoretical data for near-infrared light in the treatment of clinical fundus disease, and make it safer to use in clinical treatment.

Abstract Emerging research has highlighted the significance of aging in the right place (AIRP) by recognizing that secure and optimal housing should support an individual's unique vulnerabilities and lifestyles. Existing literature, however, has yet to consider what it means for older people experiencing homelessness and/or housing insecurity to age-in-the-right-place. In order to address this knowledge gap, a review of person-environment fit models for older people and other relevant literature was conducted to determine critical identifiers of AIRP for housing insecure older people. Findings from this literature review were then refined in collaboration with interdisciplinary scholars and community partners to establish a conceptual framework. This paper presents the resulting conceptual framework and outlines the key indicators of AIRP relevant to housing insecure older people. The proposed framework provides a practical and meaningful contribution to the literature which can be used to promote housing security among individuals often excluded from existing aging-in-place models.


This small book in the series "Mind and Medicine Monographs" should be read by every general practitioner. The author has been stimulated by Balint's seminars to study the amount of psychiatric illness in his own practice in the North of Scotland and to settle down to treat it: for, as he says, "the general practitioner is in the most advantageous position for dealing with disturbed human relationships of psychogenic origin". Though the figures are too small to have statistical validity, it may be noted that mental disorders were at the rate of 131.7 per 1,000 population, and that over 90% of these were neurotic. Dr. Primrose is to be congratulated on a clear account of painstaking work.


Packet loss is one of the top reasons for speech quality degradation in Voice over IP calls. Packet loss concealment (PLC) is a technique of facing packet loss. This article describes a system based on a deep neural network (DNN) and pre-trained frequency-consistent generative adversarial network (Fre-GAN), which aims to heal audio impairments caused by packet losses, thus impairing the quality of the audio playout. We use the sliding window method to simulate real-time audio processing and extract features within the window, a multi-layer fully connected network is applied to predict the mel-spectrogram of missing audio packets based on the context within the window, and a frequency- consistent generative adversarial network is used to convert the mel-spectrogram to a waveform and backfill it to the part of the dropped frame. We name this system PLCfre-GAN. In the 2022 INTERSPEECH Audio Deep PLC Challenge, we applied PLCfre- GAN to mitigate artificially simulated audio impairments. The processed audio we submitted surpasses the challenge zero- padding baseline and ranks the top 5 with a PLC-MOS score on the blind test dataset of 3.478. Compared with previous machine learning methods, the proposed system has shown a considerable improvement in the scores of several evaluation metrics, and the recognition accuracy of synthesized speech is also guaranteed even in the case of frequent loss.

The influence of long-term ingestion of Garcinia kola seed on the sperm count, sperm motility, and fertility was investigated in the rat. Twenty adult Wistar rats initially weighing between 150 and 160 g were randomly divided into 2 groups (A and B) of 10 rats each. Group A animals served as control and were fed normal rat feed. Group B rats were fed Garcinia kola seed diet, obtained by mixing 20g of Garcinia kola seed powder and 80g of rat feed (20% w/w). The animals were allowed their respective diets and tap water ad libitum for 8 weeks. The results obtained revealed that there was a significant difference (p< 0.05) between the sperm count (16.42 × 10 6 ± 5.25 × 10 6 /ml) and sperm motility(8.72 ± 2.33%) of the treatment group (Group B) and the respective values of the control, sperm count (89.38 × 10 6 ±  3.68 × 10 6 /ml) and sperm motility (75.56  ±  1.23%).

Flight deck operation is one of the major limitations to sortie generation capacity of the em barked air wing,and airborne weapon replenishment is the most constraining component of flight deck op erations.This paper focuses on analysis of tasks involved and sequence of time intervals during flight deck operations,considering the operational features of NIMITZ class aircraft carrier,and discussion on the ba sic structure and operating procedure of ordnance handling.It highlights that ammunition requirement should match with the capacity of ordnance handling.Analysis is also performed on the improved measures taken by FORD class aircraft carrier.


Boltzmann's equation for binary chemical reactions has been solved by the modified moment method using the equivalent of the 13-moment approximations. It was found that the transport coefficients are nonlinear in the thermodynamic forces. This nonlinearity is at least quadratic. The rate coefficient also appears to be at least quadratic in fluxes.


The Dust Bowl era was the period of drought from 1931 to 1939 that was coupled with severe wind-driven soil erosion of overgrazed rangeland and soil exposed by the use of farming practices not adapted to the semiarid U.S. Great Plains. The eroding soil from once productive range and crop lands filled the air with billowing clouds of dust that subsequently buried farm equipment, buildings, and even barbed-wire fences (Fig. 1); thus, making the living conditions of many Great Plains inhabitants unbearable. On the Great Plains wind is common and drought recurrent; therefore, farm implements and management methods were developed for producing crops under these conditions. Likewise, farmers have evolved into innovative practitioners of soil and water conservation techniques that rely on residue management practices and crop rotations with fallow periods to store precipitation in the soil for later crop use.


Many empirical and theoretical studies indicate that Brownian motion and diffusion models as its mean field counterpart provide appropriate modeling techniques for individual insect movement. However, this traditional approach has been challenged, and conflicting evidence suggests that an alternative movement pattern such as Levy walks can provide a better description. Levy walks differ from Brownian motion since they allow for a higher frequency of large steps, resulting in a faster movement. Identification of the 'correct' movement model that would consistently provide the best fit for movement data is challenging and has become a highly controversial issue. In this paper, we show that this controversy may be superficial rather than real if the issue is considered in the context of trapping or, more generally, survival probabilities. In particular, we show that almost identical trap counts are reproduced for inherently different movement models (such as the Brownian motion and the Levy walk) under certain conditions of equivalence. This apparently suggests that the whole 'Levy or diffusion' debate is rather senseless unless it is placed into a specific ecological context, e.g., pest monitoring programs.

An integrated magnetoresistive device includes a substrate of semiconductor material that is covered, on a first surface, by an insulating layer. A magnetoresistor of ferromagnetic material extends within the insulating layer and defines a sensitivity plane of the sensor. A concentrator of ferromagnetic material includes at least one arm that extends in a transversal direction to the sensitivity plane and is vertically offset from the magnetoresistor. The concentrator concentrates deflects magnetic flux lines perpendicular to the sensitivity plane so as to generate magnetic-field components directed in a parallel direction to the sensitivity plane.


A firewall system is placed at the entry point of an enterprise network to examine the packets that attempt to enter the network and decide based on some underlying firewall F whether to accept or reject these packets. A firewall system usually executes O(n) steps to examine each incoming packet and determine whether to accept or reject this packet, where n is the number of rules in F . The number of rules in a practical underlying firewall F can be large, for example, several thousands. Therefore, the number of steps that need to be executed by a firewall system to determine whether to accept or reject an incoming packet can be several thousand steps. However, by outsourcing parts of the functionality of the firewall system to clouds, the number of steps to be executed by the system can be reduced from O(n) to O(1). In this paper, we design a class of outsourced firewall systems that take advantage of clouds to reduce the number of steps to be executed by the system from O(n) to O(1). Unfortunately, clouds can be unreliable causing two types of attacks to our class of outsourced systems: a verifiability attack and a privacy attack. The verifiability attack is that the cloud may not execute the outsourced functionality of the firewall system correctly. The privacy attack is that the cloud may leak the rules of the underlying firewall F to potential attackers of the system. To defend against these two attacks we design two classes of outsourced systems, named Verifiable, and Private Systems. The verifiable system is designed by allowing the system to observe the steps that the cloud executes and verify in O(1) steps that the observed steps are the ones that the cloud should indeed execute. The verifiable system defends against the verifiability attack but does not defend against the privacy attack. The private system is designed from the verifiable system by ensuring that the cloud cannot deduce the rules of the underlying firewall F and so cannot leak these rules to potential attackers of the system.


Four varieties each of Long Staple and Short Staple cotton were tested over five and four dates of planting, respectively, in this study. The first date of planting for the Long Staple cotton was the 18 of March and for Short Staple th cotton the 1 of April. The latest planting was May 13th. Cultivars of differing st maturities were tested for both long and short staple cotton to determine their optimal planting time. Many agronomic parameters were evaluated to determine the effect of different planting dates


Fifty subjects performed 106 simulated dives at a final ambient pressure of 0.7 at (3000 m above sea level). One hundred and forty-three subjects performed 278 actual controlled dives at altitudes 900-1700 m above sea level. From the experience of these dives, air-decompression tables for altitudes 0-3200 m above sea level were calculated. Tables up to 2000 m above sea level were tested on humans under wet conditions.

(II) Products of the Pyrolysis of Some 2-0xazolidinones Ryohei ODA, Masahiko MIYANOKI and Masaya OKANO Bulletin of the Chemical Society of Japan, 35, 1910 (1962) The products obtained by the pyrolytic decarboxylation of 2-oxazolidinones have been investigated, chiefly by infrared analysis. In the case of 2-oxazolidinone, the products are 1(;:?-hydroxyethyl) -2-imidazolidinone, 1[;:?(l-azilidinyl)ethyl] -2-imidazolidinone (somewhat uncertain), and poly (ethylenimine) having a 2-imidazolidinone ring at the chain end. On the other hand, the only products from 3-p-chlorophenyland 3-p-nitrophenyl-2-oxazolidinone are believed to be low molecular weight polymers of the corresponding ethylenimines. From 3-acetyl-2oxazolidinone, a considerable amount of 2-methyl-2-oxazoline, which seems to arise from the rearrangement of N-acetylethylenimine, is isolated, in addition to the corresponding poly (ethylenimine). On the basis of the products obtained, a possible mechanism for the pyrolysis has been proposed. Studies of 2-0xazolidinones.

(1) This decomposition is an autocatalytic reaction, in which the amined formed acts as a catalyst. (222 ) ABSTRACTS (2) In the decarboxylation of 3-aryl-2-oxazolidinones, the electronic effect of the substituent on the benzene ring indicates that the fission of the N-C bond of the urethane group in the 2-oxazolidinone ring is rate-determining. (3) The initial rate of the aliphatic amine-catalyzed decarboxylation of 3-aryl-2-oxazolidinones is of the pseudo-first-order; it also depends on the concentration and structure of the amine. A mechanism has been proposed which involves a nucleophilic attack of amine on the carbonyl-carbon atom. An amine having an hydroxyl or amino group on the ,B-carbon shows a large rate-acceleration; this suggests the simultaneous electrophilic participation by the active hydrogen of these groups. (4) The initial rate of the decarboxylation of 2-oxazolidinone itself, catalyzed by aliphatic amine, is of the second-order in oxazolidinone and of the first-order in amine. From this a concerted mechanism has been inferred, in which the amine acts as a nucleophile and the other oxazolidinone acts as an electrophile.S (2) In the decarboxylation of 3-aryl-2-oxazolidinones, the electronic effect of the substituent on the benzene ring indicates that the fission of the N-C bond of the urethane group in the 2-oxazolidinone ring is rate-determining.

(IV) The Addition of Schiff Bases to Diketene Ryohei ODA, Shunichi TAKASHIMA and Masaya OKANO BUetin of the Chemical Society of Japan, 35, 1843 (1962) Treatment of diketene with N-benzylidene-t-butylamine afforded a cyclic adduct, adduct, 1-t-butyl-6-phenyl-2,4-piperidinedione, in an excellent yield. Simlar reactions with N-methylene-t-butylamine and N-methylenecyclohexylamine also gave the corresponding piperidinediones, but the yields were very low. New Addition Reactions.

This result is contrast to other Lewis acid-catalyzed reactions (d. Makromol. Chem., 39, 243 (1960) ; 43, 149 (1961)).


Abstract A new Density-Functional (DF) formula is constructed for atoms. The kinetic energy of the electrons is divided into two parts: the kinetic self-energy and the orthogonalization energy where these concepts are borrowed from the pseudopotential theory. For the radial part of the ortho-gonalization energy which replaces the radial part of the Fermi-energy of the Thomas-Fermi model we derived the expression where p is the momentum, the ak's are constants and pε is the momentum width associated with the self-energy for which an expression is derived. Calculations were made for the total energies of neutral atoms, positive ions and for the He isoelectronic series. For neutral atoms the results match the Hartree-Fock energies within 1 % for atoms with N < 36; for atoms with N > 36 the results generally match the HF energes within 0.1%. For positive ions the results are fair; for the He series we achieved four or five-digit agreement between our energies and the HF results. For molecular applications a simplified model is developed in which the kinetic energy consist of the Weizsäcker term plus the Fermi energy reduced by a continuous function η(N). It is shown that the η(N) can be constructed in such a way that the energies computed closely approximate the HF energies for all neutral atoms.


The title salt, C24H24N+·BF4 −, is one of two possible diastereoisomers having a different configuration of the asymmetric centre in the α-phenylethyl substituent, whose absolute configuration was established to be R. The two phenyl substituents of the cation have a cofacial orientation, albeit with a long centroid–centroid separation of 4.129 (3) Å. The crystal structure exhibits numerous C—H⋯F contacts between counter-ions, with the tetrafluoridoborate anion surrounded by five iminium cations.


Abstract A state-of-the-art Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFC) stack was investigated. The stack was a pre-commercial one, with a nominal power output of 600W. The study was focused on the electrical performance and the possible thermal energy recovery. Moreover, to evaluate the technology limitations for Distributed Generation (DG) applications, a 15 h test cycle with slow electrical power variation was performed. At the end of the tests, it was envisaged the capability of proper energy conversion efficiency. This technology appears promising for the high conversion efficiency of natural gas chemical energy into electrical energy, with proper perspectives for distributed generation.


The main aim of this paper is to perform Functional Principal Component Analysis (FPCA) taking into account spatio-temporal correlation structures, in order to fill in missing values in spatio-temporal multivariate data set.A spatial and a spatio-temporal variant of the classical temporal FPCA is considered; in other words, FPCA is carried out after modeling data with respect to more than one dimension: space (long, lat) or space+time. Moreover, multidimensional FPCA is extended to multivariate context (more than one variable). Information on spatial or spatiotemporal structures are efficiently extracted by applying Generalized Additive Models (GAMs). Both simulation studies and some performance indicators are used to validate the proposed procedure, showing that, especially in presence of long gaps, spatio-temporal FPCA provides a better reconstruction than spatial FPCA.

Roadford reservoir completes South West Water's major three reservoir strategy quadrupling storage in the region.

The paper examines how environmental issues have impacted on the scheme and demonstrates how effective planning and management can minimize effects and concerns on a major civil engineering project.

Strategy changes from river regulation to gravity water mains have given reduced environmental impact on rivers and a lowering of power costs, also giving environmental gain. The setting of strict environmental protection measures within contracts and a determined policing policy during construction have produced low levels of pollution incidents during construction.

The paper highlights the benefits of working with environmental groups to secure a successful conclusion not only of the construction element but how that construction can be blended into its local environment. Costs are identified and the authors point to the substantial public relations benefits that can be gained with the successful management of environmental issues.


The delay of the school term in China, caused by the Corona Virus Disease 2019(COVID-19)pandemic, reinforced the importance of remote teaching. The latter enabled teaching operations to continue nationwide and provided colleges and universities with opportunities to carry out education and teaching reforms that are also aligned with the rapid development of technology. Upon considering remote teaching operations in China University of Geosciences, Beijing, this paper puts forward recommendations for teaching and education management practices. We propose that colleges and universities break free from the restraints of traditional teaching methods, establish a security system of online courses, offer high quality online contents, and accelerate the construction and sharing of effective courses.


The development of a numerical model capable of simulating the forming processes characterized by additional reversible movement of tools is the subject of this paper. The major assumption of this process is the introduction of additional shear stresses into the material in order to induce the strain path change effect. The scope of the problem is very broad, so the focus in the present work is on the process of flat rolling with additional oscillatory movement of rolls along their axes. Due to the sophisticated nature of this process particular attention is paid to the reduction in computational time by minimizing the number of required finite elements. The developed model is used to study differences in material behaviour during rolling with different roll velocities. A detailed description of the developed numerical model and examples of obtained results are presented in this paper. A comparison with experimental analysis is presented, as well.


Applications for Mobile-Learning, used in conjunction with strategies based on games, provide new opportunities for the learning process in the physical and virtual worlds. Although previous works evaluated location-based mobile applications (and its variations), most of them focused almost entirely on specific metrics, leaving the player's perspective aside. This paper presents study results for the evaluation of mLearning applications from the students' perspective regarding the learning experience based on location and the game elements that might make the learning process more appealing to them. The study collected major game elements from the literature and applied questionnaires to 53 students from public high schools (junior high) in two states of Northeast Brazil. The results suggest that the majority of students have interest in this learning approach and consider most of the analysed game elements important to promote learning motivation, even though there are elements that are not as appealing. The paper contributes to the design of gamified location-based m-Learning applications in the sense that it provides insight into the importance of their requirements players perceive and may thus, serve as a guide for such applications versioning.


A multivibrator circuit used as a delay element. A pair of complementary signals to be delayed control the transistors of a long tailed pair so as to generate charg ing and discharging currents for a capacitance coupled between first and second current branches of the multi vibrator circuit. The delay time depends, among other parameters, on the exact values of these currents. In order to avoid the necessity of providing very accurate values of the signals for generating the proper current values, a current division is applied, to the circuit by adding in parallel to each long tailed pair transistor, a constant current source. As a result the currents in the multivibrator circuit can be switched between two ex actly determined current values by alternately switch ing the long tailed pair transistors fully on and off. The same kind of current division is applied to the circuit in order to achieve a voltage swing at the output which is independent of the current adjustment. .307/25


Genetic variation resulting from changes during somatic development in modular organisms may be inherited by subsequent generations due to the late development of their germ line. As a consequence, both sexually and asexually produced offspring may be genetically variable. The presence of heritable intraclonal variation and the great life history variation among modular organisms requires that evolutionary theory does not limit selection to only that occurring among individuals resulting from meiosis and zygote formation. To allow for variation within clonal lineages, and encompass a wide variety of life histories, we construct a simple model of selection among modules in life histories that contain both haploid slid diploid phases, such as that seen among many multicellular algae. Selection among modules is a demographic process with module performance depending on its genotype at a single locus with two alleles. The model is used to simulate the spread of a beneficial allele in life histories that vary in the relative amount of sexual and asexual reproduction. The time taken for allele fixation is shown to depend on both demographic and genetic factors. (Less)


Bowel dysfunction is a common complaint among patients with brain damage due to stroke and traumatic brain injury. The aim of this study was to investigate the prevalence of bowel dysfunction (anal incontinence and intestinal constipation) in patients with brain damage due to stroke and traumatic brain injury admitted for rehabilitation. This is a retrospective case series study, based on the analysis of data from 138 charts of patients admitted in the first half of 2009. The prevalence of bowel dysfunction was 41%, with 33 (24%) cases of anal incontinence and 37 (27%) cases of intestinal constipation. Motor impairment, mobility aid, changes in memory and communication were associated with the presence of anal incontinence. The prevalence of bowel dysfunction is high in this population. Early identification of the symptoms and its related factors promoting bowel retraining, may help to improve the quality of life of patients with bowel dysfunction. DESCRIPTORS: Constipation. Fecal incontinence. Stroke. Traumatic brain injury.

Introduction: Foetal origin of posterior cerebral artery is one among the common variants in the circle of willis. In case of cerebral injury due to thromboembolic stroke, the presence of foetal type of PCA may modify its severity and the territory involved. The purpose of this study is to review and to evaluate the potential clinical significance of foetal type PCA in ischaemic stroke. Aim: To analyse whether foetal PCA and its types are associated with ischaemic stroke. Materials and Methods: This is an analytical cross-sectional study conducted from January 2019 to January 2020 to assess the PCA in the 174 patients referred to Magnetic Resonance Imaging (MRI) Brain and diagnosed as ischaemic stroke. Data was entered using Excel sheet and analysed using R v.3. 5.1. Descriptive analysis was performed followed by bivariate analysis. Results: There is no statistically significant relationship between the presence of foetal PCA and ischaemic stroke and the p-value is 0.936. Conclusion: There is no significant association of presence or absence of partial or complete type of foetal PCA with ischaemic stroke. No significant association was also found between the presence of foetal PCA and vascular territory of infarct and laterality of ischaemic stroke.


The concept of 'strangers' provides rich ground encompassing notions of xenophobia, inter-cultural aspects of colonialism, perception of 'Self and 'Other', and living in a global society with crosscultural relations. "Strangers" is the title which the Australian novelist Kate Grenville gives to the prelude of The Secret River (2005). This also is the title of a piece of creative writing completed in the senior English classroom as a pre-reading exercise to excerpts from the novel. The pupils write:Everyone knows what it's like to feel like a stranger. There are situations in life where you don't have known people around you. Especially at the beginning of new sequences like starting school, university or moving to a new town. It feels uncomfortable.It's pretty hard to move. You can say that for sure. If you move to a new flat or even a new city it can really be a pain in the arse. A whole lot to do and all the new impressions of your new surroundings. And all the new people are strangers to you. You need some time to assimilate to the new situation.In my life nothing is strange. I just sit in my nice, tiny house with a nice tiny smile on my face. I seldom leave Hanover. [...] This summer I'll go to Italy so I need to take a piece of my wallpaper, my pillow and a C D with sounds of my street with me.Many sentiments are expressed here. Fear of the new and unknown, pain, the need for time to assimilate, the notion of safety. How can we help these pupils to cope with these feelings and the borders between safety and adventure which they are sure to encounter?In order to find answers, the reality of the German grammar-school classroom must first be outlined. It constitutes a highly heterogeneous body of learners with a wide variety of cultural backgrounds which can be exemplified by the following Grade-Eight English class with twenty-nine pupils, twenty of whom are of migrant descent.Fifteen children are from Turkish families and speak German and Turkish at home.Two of the Muslim girls wear a headscarf and do not participate in school swimming activities.Two boys come to afternoon classes late on a regular basis due to their religious commitments in the mosque. The families of these children do not allow them to attend school concerts which take place in the EvangelicalLutheran Church across the road from school.Two boys have emigrated with their families from Sri Lanka to live in Hannover and speak German as a second language.One boy's family is from Vietnam.One girl lived in Sweden for a number of years.One girl's father is French; her mother is German; and she's bilingual.Nine of the twenty-nine children are mono-lingual Germans. They constitute a minority group.These pupils, most of whom completed primary school in Lower Saxony, have been studying English as a second language for more than five years. From Grade Six it is compulsory for German grammar-school pupils to study a further foreign language. These pupils are thus not only learning English but have, in addition, been reading either French, Latin or Spanish for over two years. They speak German, yet the large majority of them have a command of a further language as a result of their family origins. This body of pupils perhaps reflects a cross-section of the surrounding community, a constellation not unusual in contemporary German society.Difference and diversity in this multi-lingual, multicultural group of young people is increasingly the cause of conflict, even xenophobic behaviour. The school principal has organized a team of teachers who work systematically on finding methods to cope with these issues. Some teachers train an extra-curricular team of mixed-aged pupils to become conflict mediators in the schoolyard. Others have organized a guest speaker on Islamic beliefs and culture, who was invited to address the teacher's questions and to provide a platform for discussion. …


The issue of global climate change brings together the realms of scientific inquiry, technology choice, and social discourse in a manner and with an urgency that are rather unique in the area of science, technology, and society. Global climate change is the first instance of an unintended consequence of technological devel opment with effects that are truly universal. It repre sents a process the repercussions of which are being felt not only by every human being but also by every living thing on earth; one that has the potential to change the face of the planet itself. Understanding the true nature of this problem and devising an effective response to it will require input from every field of inquiry, from biology and chemistry to ethics and education, from anthropology and policy studies to mathematics and computer science. Moreover, these inputs must be integrated, with inquiry in one area informing and being informed, challenging and being challenged by the others. Science, technology, and society, as an approach to inquiry dedicated to integrating knowledge from a broad spectrum of disciplines, is well suited to the task of providing the interdisciplinary perspective neces sary to fully explore the issue of global climate change. Most of the research directed to this issue has been conducted within the boundaries of the various tradi tional disciplines. This is not surprising and not alto gether bad as the paradigms that each discipline repre sents generally facilitate the advancement of knowledge within the discipline (Kuhn, 1970; Laudan, 1977). The disciplinary approach, however, is inade quate when it becomes necessary to place scientific knowledge in a social context, as is the case when the knowledge must provide a basis for social action. This approach is also inadequate when the problem being investigated is complex, having dimensions that tran scend disciplinary boundaries. When the issue is highly complex and the ultimate objective of the research is to inform policy, as is the case in the global climate change discourse, only an interdisciplinary approach such as STS can ultimately produce the nec essary knowledge. The idea for this special theme issue of the Bulletin of Science, Technology & Society was born at the 14th conference of the National Association for Science, Technology and Society, which took place in Balti more, Maryland, in March 1999. Taking place 14 months after the Kyoto Conference of the Parties to the Framework Convention on Climate Change, which produced the first binding agreement for the reduction of greenhouse gas emissions, the NASTS meeting pro vided an ideal stage for the presentation of findings of interdisciplinary research focusing on the issue of global climate change. Of the numerous papers dealing with this topic that were presented at NASTS 14, six were selected for this issue of the bulletin. Two additional papers were selected to enhance the international dimension of this global climate change theme issue. The eight theme papers, necessarily, provide only a small sample of the multitude of perspectives that STS brings to the global climate change discourse. However, they encompass a very diverse range of approaches, from econometric modeling to ethics and from policy analysis to political economy. The theme and tone of this issue are set by the article by W. Michael McCabe, which gives an overview of the potential environmental and social consequences of global climate change, describes the political cli mate that prevailed at Kyoto, and discusses the interna tional negotiations that followed Kyoto and U.S. poli cies for greenhouse gas emission reductions. This article clearly and succinctly reviews the international and U.S. domestic controversies surrounding the implementation of the Kyoto Protocol, and it starkly lays out the challenge faced by humanity as a whole and by the United States in particular. Mr. McCabe is the regional administrator of the U.S. Environmental Protection Agency's Middle Atlantic Region. His arti cle brings to this issue almost a quarter century of

This paper is the writing of a non-Indigenous Australian. It considers the interplay of frontier history, culture and, latterly, a sustainable environment, through the lens of Australian national identity. It argues that a reformulation of the frontier pioneer identity is necessary to a sustainable culture and environment. It puts the case that coming to terms with nonIndigenous and Indigenous frontier history is part of this. It revisits the so-called 'history wars' and considers the concept of 'war' as a negative construction that has reinforced a public binary view of Indigenous/non-Indigenous history, that has continued in politics. Broadly, this binary positioned one group who accepted that Indigenous people were dispossessed and subjected to brutal treatment; and a second group who considered that frontier men were largely noble, and that while there may have been a bit of 'messy stuff' on the frontier it was best not dwell on it. The politics of these two views, as played out in the public arena, have been confrontational. Windschuttle's (2000; 2002) recent written work, and more importantly his skills in promoting the position of a benign frontier in the media, was the catalysis in promoting the binary into a 'war'. The paper argues that the way forward is to move beyond this binary in history and politics, and that key to this is a more mature understanding of the constructed myth of the 'noble pioneer'.


Objective To investigate the relationship of MRI findings with total bilirubin level and neonatal behavioral neurological assessment( NABA) in neonates with hyperbilirubinemia.Methods According to serum bilirubin level a total of 73 mature newborns with hyperbilirubinemia( study group) were divided into mild elevation group( n = 27),moderate elevation group( n = 28) and severe elevation group( n = 18).Other 29 healthy full-term neonates were collected as normal control group.Cerebral MRI was performed in all neonates.Additional1H-MRS examination was employed in 6 neonates of the study group as well as in 3 healthy neonates of the control group.NABA determination was carried out in the neonates of the study group.Results In the moderate elevation group and severe elevation group( serum total bilirubin level 342μmol / L),the mean signal value of globus pallidus was approximately 1014 ± 205.50.Statistically significant difference in the mean signal value of globus pallidus existed between the study group and the control group( left side: P =0.035 and P = 0.007 respectively; right side P = 0.041 and P = 0.007 respectively).The degree of MR signal enhancement had a parallel relationship with NABA scores.Positive linear correlation existed between the average signal values of globus pallidus and total serum bilirubin levels.1H-MRS examination indicated that in the study group the differences in the ratios of NAA / Cr,Cho / Cr and Cho / NAA were not statistically significant.Conclusion The increased MRI T1 WI signal of globus pallidus can be used as an index for clinical evaluation of brain injury in neonates with hyperbilirubinemia.The application of1H-MRS examination in newborns with hyperbilirubinemia needs to be further studied.


We propose an approach to obtain gauge-invariant maximally path-dependent operator definition of the gluon transverse-momentum dependent distribution function (gTMD). We demonstrate that the evolution equations for the gTMD can be derived from the shape- variation integral-differential equations formulated in the coordinate space.


At the outcrops of the Tupe Formation in the La Herradura Creek, San Juan Province, two transgressive events are recorded, which range from few meters to tens of meters in thickness. These strata correspond to the stratotype of the faunal Tivertonia jachalensis-Streptorhynchus inaequiornatus Biozone. An evaluation of the timing of the two marine transgressions is made on the basis of palynological assemblages and available radiometric ages. A short-lived transgression is recorded in the latest Bashkirian-early Moscovian, and then a substantial sea level fall took place forming an irregular incision surface. Later, a major high eustatic sea-level occurred during the middle Moscovian resulting in a more important marine ingression. The palynological assemblages associated to the older transgressive event indicate the presence of the Raistrickia densa- Convolutispora muriornata (DM) Biozone (Subzone B). Palynofloras referred to the Subzone C of the DM Biozone characterize the strata of the younger transgression that also bear marine fauna of the Tivertonia jachalensis-Streptorhynchus inaequiornatus Biozone. Correlations with other Pennsylvanian outcrops in the region give support to the stratigraphic scheme here proposed.


Emotions are the emergent property of the human mind like consciousness and are emerging from the interaction among various core cognitive processes. Cognitive models are available for other core cognitive processes such as problem solving, decision making, memory, reasoning, etc. Though it is not clear about the origin of emotion, through emotional response, it is possible to create cognitive models of emotion. One kind of physiological or emotional response to the particular event via face is the facial expression. Human face plays an important role in interpersonal communication and considered as important channel compared to other communication channels while conveying mixed mode of information. Facial expression provides more visual cues about internal mental states of human being and is caused by muscle contraction to facial skin. As a result, there is a change in the appearance of facial features, say facial components such as the eyebrows, nose, and mouth. As facial expressions are natural feedback to others, it can be used in a wide variety of computer applications in which the system can recognize the human internal emotional state from the visual cues and can react accordingly. By developing valid and reliable methodologies to measure facial behavior, it can be used as a natural interface in various applications such as human–computer interaction, computer surveillance, gaming, entertainment, teleconference, medical field, education, etc. In this article, the emotion of human is estimated using suitable geometric features from the facial expressions. The obtained geometric feature based pattern to recognize the expression can be effectively used as a feedback mechanism in a classroom to measure the mental state of the students. Also, a suitable feedback scheme can be devised to improve the teaching-learning process. Facial Action Coding System (FACS) proposed by Ekman and Friesen (1978) has been used for the manual interpretation of facial expression. This is the standard code followed by most of the researchers for facial behavioral study. This approach contains facial muscle movements in terms of 46 Action Units (AU) and a combination of these action units are used to identify various expressions. Based on the description of AUs, six common facial expressions such as angry, disgust, fear, happy, sad and surprise across various cultures are identified (Ekman & Friesen, 1971). This recognition is purely based on the changes to facial features like eyes, nose, mouth, etc. After FACS, this research issue has gained much interest on related fields like image processing for face detection, facial feature point extraction and tracking, etc. Various solutions are proposed for this issue and it can be broadly classified into two, namely, geometric and appearance based methods. Because of the facial configuration, which is not common for all, early works started to use the geometric deformation of features to recognize an expression in which, facial feature changes are measured in terms of relative distance and angle with reference to neutral face. Similar geometric deformation vectors are used in face modeling technology to create personalized avatars in virtual world. The talking head system has been proposed (Liu, Zhang, Jacobs, & Cohen, 2001), with linear combinations of AU stored as a mesh deformation vector. A facial expression is generated by adding A.

Time-frequency distributions (TFDs) are computationally intensive methods. A very common class of TFDs, namely quadratic TFDs, is obtained by time-frequency (TF) smoothing the Wigner Ville distribution (WVD). In this paper a computationally efficient implementation of this class of TFDs is presented. In order to avoid artifacts caused by circular convolution, linear convolution is applied in both the time and frequency directions. Four different kernel types are identified and separate optimised implementations are presented for each kernel type. The computational complexity is presented for the different kernel types.


SUMMARY This paper demonstrates a power supply noise reduction using on-board stubs. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply noise of the designed frequency. Preliminary experiments show that 87% of the designed frequency noise component is suppressed when stub patterns are written on a power supply area on a PCB board for a 1.25 GHz operating LSI. The results show the possibility of the stub on-chip integration when the operating frequency of LSIs becomes higher and the stub length becomes shorter.


Objective: To find out effectiveness of steel wool debridement in second degree burns Study design: prospective study Place and duration of study: From January 2008 to December 2010, plastic surgery department, Nishtar Hospital Multan Materials and Methods: A total of 300 burn cases were admitted in burn unit / plastic surgery department, Nishtar Hospital Multan. During the study period all the details of patients regarding their Registration data, history, site of the burn, TBSA affected, degree of burn , depth of burn, presence or absence of slough in the wound, medical report, operative notes, pre and post operative photographs, duration of hospital stay and outcome were filed individually. All the data was analyzed using SPSS 11 software. Results: We included 63 patients who had partial thickness burns. 35 patients had superficial dermal burns and 28 had deep dermal burns. Out of 63 patients 36 were males and 27 were females. Their age ranged from 13 years to more than 65 years. (Table I) It can be best appreciated that majority of patients in our study were in the age range of 21-40 years. Conclusion: Steel wool dermabrasion removes the necrotic tissue and reduces the inflammatory response that helps in healing and prevents transition into deep thickness burns. It also reduces the septic load of the wound. Dermabrasion with the steel wool is effective, simple, and cost effective and it negates the need of grafting in many of the patients with partial thickness burns.


In this paper we report on a newly developed multigate nanowire (NW) based field-effect device (NWFET) where the transistor type is freely selectable by the application of a control-voltage, adding to design flexibility in integrated circuit fabrication. Moreover, the midgap Schottky-barrier source and drain contacts of the NWFET make it feasible for the usa in high temperature environments, since the devices posses both stability against high temperatures and low OFF-state current at the same time. This makes the presented NWFET a multi-purpose device for many specific circuit applications.


Forest fires are one of the environmental problems that often occur and are considered important so that they become local and global concerns. In Indonesia, forest and land fires (karhutla) continue to occur, especially in Sumatra, Riau and Kalimantan. Great forest and land fires have occurred in Riau and Kalimantan in 1997/1998 with severe impacts, including health problems, land accidents, aircraft crashes and smoke effects reaching neighboring countries. Law enforcement for environmental management is still difficult because of the difficulty in proving and determining the standard criteria for environmental damage Forest fires are one of the environmental problems that often occur and are considered important so that they become local and global concerns.

The investigation is focused on the perceptions that teachers have in three different scholar systems, in relation to sexual diversity. The methodology was qualitative–descriptive. Information gathering is conducted through semi–structured interview to selected teachers. The analysis was performed following the assumptions of Grounded Theory. The two axes on which turned the research were related to the notions of sexual diversity that interviewers had and their ideas about how, in their opinion, should be addressed problematic situations that LGBT students are involved in different school spaces. The main findings of the research were those that interviewers really know what they talk about when referring to sexual diversity, identifying features and ideas related to sexual orientation, as well as knowing different strategies and/or methodologies to help to resolve problematic situations in scholar systems.

The metabolic goal of therapy in gestational diabetes (GD) is to maintain euglycemia, and when it is not achieved with diet alone, insulin therapy is added (1). Physical training has both acute and long-term effects on insulin sensitivity, insulin secretion, and glucose metabolism in both nondiabetic and diabetic subjects (2), and the benefit of training has also been shown in patients with GD, where controlled training achieves euglycemia with no need for insulin treatment (3). Nevertheless, physical exercise of moderate intensity has been associated with uterine contractions unless performed with the arms (4).

The clinical observation that light postprandial exercise …


The effects of a simplified production process on the yield, protein content and differential scanning calorimetric analysis of a sesame protein concentrate were studied. The results were compared with those for similar products obtained by the traditional method. The protein content of the (spray-dried) sesame concentrate obtained by the simplified process (549 g kg−1) was similar to that of the concentrates obtained by the traditional method (515–565 g kg−1). Spray-dried samples showed higher Td and Tm and lower ΔH than freeze-dried samples. In addition, the chemical composition, nutritional quality and physicochemical and functional characteristics of the sesame protein concentrate obtained by the simplified process were compared with those of a similar soybean product. The protein, lysine and calcium contents of the sesame concentrate were lower than those of the soybean concentrate, but the digestibility of the protein was the same for both products. The phytic acid content of the sesame concentrate diminished significantly, but was still higher than that of the soybean concentrate. The water absorption and protein solubility were higher for the soybean concentrate, whereas the oil absorption and viscosity at pH 3 were higher for the sesame concentrate.

Magnesia whiskers grown via vapor phase reaction were studied by means of X-ray topography, and optical and electron microscopies. The results obtained were as follows:1) No internal defects were detected by X-ray topography, but contrast changes were found at tips of the whiskers. There contrast changes may be due to the inclusion of impurities which take part in the growth.2) Triangular closed growth hills were found on {111} surface of a [112] whisker.3) The surfaces of whiskers having diameters smaller or larger than a few micron were bounded by smooth or heavily stepped faces, respectively. Mechanical properties may be controlled by the surface structure as well as the internal structure.


Reviewed by Lisa Mullikin Parcell Wichita State University Willa Cather, Sherwood Anderson, Ernest Hemingway, Zora Neale Hurston, James Agee, Walker Evans, and RobertPennWarren used different aspects of journalism as stylistic and structural tools in their writing. These stylistic approaches allowed the writers to appeal to elite groups of sophisticated readers and, at the same time, become part of the national discussion addressing the changing culture and community of America. During the interwar period, small magazines and academics became increasingly influential in national discourse and demanded innovation in writing style. These modernist writers melded art and journalism as a way to meet the expectations of their critical audience and attract a more popular audience. The writers used standard elements of popular journalism as a way to experiment with perspective, narration, plot, and genre. The resulting literature both appealed to a broad public and a select audience of educated, sophisticated readers. Humphries argues that these writers used their training as journalists and/or critics to write in a style that appealed to a common ground and allowed them to also question and challenge social issues of the day and prevailing literary values.

This article represents reflections on current social and legal issues for people given a mental diagnosis, from a lived experience perspective. The article addresses:
 • Major obstacles to social and legal justice for people with this lived experience.
 • What differences people with lived experience have been able to make.
 • Key challenges for the British Association of Social Workers (BASW) from a lived experience perspective.
 The UN Convention on the Rights of Persons with Disabilities is used as a basis for the reflections. The article has a particular emphasis on literature written, or substantially influenced by disabled people, including people with lived experience of receiving a mental health diagnosis. The user-led group Liberation is utilised as an example of what difference people with lived experience can make to obstacles which they experience. Three challenges are made to BASW, related to utilising the Convention to ensure social and legal justice for us, confronting human rights breaches in the draft Mental Health Bill and working in partnership with user-led groups in these spheres.


An interpretation of de fi nitional uncertainty as a scattering parameter (standard deviation) of the contour estimate of the error of inadequacy is given for the equations of the method of indirect measurement. The problem of calibration of a thermometer from the Guide to the Expression of Uncertainty in Measurement is considered. In solving the calibration problem, an estimate of the de fi nitional uncertainty obtained this way amounts to 74.1% of the standard uncertainty of the corrections.


The prognosis of primary liver cancer is very poor. The effects of a single therapeutic method in treating liver cancer are limited. Multimodality combined therapy may make up for theshortcoming of a single method,exert additive or synergistic effects and improve the survival of patients with liver cancer. The advance of combined therapy which surgical resection plays a main role in treatment,combined palliative surgical therapy and nonsurgical combined therapy for unresectable liver cancer were reviewed.


The objective of this work is the use of artificial neural networks and cellular automata to support urban planning decisions in Mexico. We propose an automated model that predicts vertical urban growth, using socio-economic and geographic factors. A multidisciplinary model is presented that manages artificial neural networks, cellular automata, spatial analysis methods, image processing that allow different scenarios of urban growth to be projected and simulated. All of this is built into QGIS through the Python programming language. The model is tested in Mexican cities such as Mexico City, Guadalajara and Monterrey during the years 2015-2020. Reliability ranges from 72% to 76% were obtained, validated by: i) the average number of projected skyscrapers, ii) Position using the Kappa index, and iii) Value in the image using the Jaccard index. With this we propose a technique that allows better informed decisions for urban planning and anticipate new infrastructure needs, projections and regulations.


The electric radiation fields produced by lightning return strokes, stepped leaders, and intracloud discharge processes have been Fourier-analyzed to determine amplitude spectra for these processes from about 100 kHz to 20 MHz. The fields were recorded under conditions where the lightning locations were known and where the field propagation from the lightning sources to the recording site was entirely over salt water. The spectra for return strokes show an f−1 frequency dependence from 100 kHz to 2 MHz, an f−2 dependence between 2 and 10 MHz, and an f−5 decrease above 10 MHz. In the 1 to 20 MHz range, the spectra of the initial fast transition in return strokes, the initial fast-rising portion of leader steps and the fast transitions in positive intracloud pulses are surprisingly similar.


The flexible microactuator (FMA) is a new pneumatic rubber actuator which has been applied to various kinds of miniature robots. While conventional FMAs are reinforced with fiber in the circumferential direction to resist deformation in the radial direction, the fabrication of FMAs with homogeneous rubber and without fiberreinforcement is necessary in order to manufacture them at reasonable cost. In this work, an optimum design of an FMA without fiberreinforcement is accomplished using a nonlinear FEM based sensitivity analysis, so that the maximum stress and the radial expansion are decreased, and the bending angle is increased. The resultant deformation of the optimized FMA agrees well with the experimental results.


The domus de janas are the typical rock-cut tombs of Sardinian Late Prehistory. Many of them are decorated. Motifs are made with different techniques: painting, sculpture and incision. Architectural elements, busts, cattle and sheep, and horn-shaped features are represented. Painting is generally used to decorate the ceilings, the jambs of doors, walls and false doors. The difficulty of detecting traces of paint complicates the identification of the ancient use of this decorative technique. The aim of this work is to describe the great utility of the plugin DStretch, extension of the ImageJ software, as a method of computer analysis and processing of multispectral images on the paint traces at the sides of the Perdonighéddu domus de janas (Sorgono, NU, Sardinia, Italy). This system opens up new perspectives in the study of the paintings found in the domus de janas, by allowing a crisper image of the decoration, through an alteration of digital photography chromatic scale. The analysis of the images of this grave reveals the presence of traces of painting that decorate the sides of the entrance by forming two doorposts supporting the lintel.


A theoretical study has been conducted to explore the mechanics of self-organizing channel networks with dimensions in the submicron range and nanorange. The channels form by the partial release and bond back of prestressed thin films. In the release phase, the film spontaneously buckles into wrinkles of a certain wavelength, followed by a bond-back phase in which the final channel geometry is established through cohesive interface attractions. Results are presented in terms of the channel spacing, height, and width as a function of the film stiffness, thickness, eigenstrain, etch width, and interface energy. We have identified two dimensionless parameters that fully quantify the network assembly, showing excellent agreement with experiments. Our results provide valuable insight for the design of submicron and nanoscale channel networks with specific geometries.

Creating programming projects that engage students has been a continual challenge in computer science. Ideally, programming projects should require student to reflect upon and apply programming concepts and help them develop creativity, problem-solving, and other skills for the workplace. The use of real-world problems is one possible solution to the issue but it comes at the cost of increased complexity, size, and burden on the instructor. One approach to reducing these costs is to design (or redesign) programs, developed as part of a research agenda, for use as student projects. Designing these programs for flexibility, adding extra, student-appropriate, feedback and identifying portions of the code that could become interesting student projects helps support both research and classroom learning at the same time. By explicitly designing with projects in mind, instructors can control the complexity and size of these real-world problems and can, potentially, create a platform that can support multiple types of student assignments. This poster describes the experience of redesigning a UML diagramming tool to implement this idea and provides examples of the design decisions made, lessons learned during the process, and other programs that could be used in a similar fashion. Future work includes evaluating the students' reaction to the projects and whether enough support is being provided.
