A 38-year-old female presented with massive hematochezia. She was previously healthy, not on medications and has had two healthy children. She reported a miscarriage that required evacuation of the uterus about 4 years ago. On examination, she was pale and lethargic. Abdominal examination revealed left iliac fossa tenderness and rectal examination showed dark stools with blood clots. There were no rectal mass or haemorrhoids. Vaginal examination was unremarkable. She was afebrile with borderline hypotension at 100/60 mmHg, tachycardic at 120 beats/min, and tachypnoic at 23 breaths/min. Her haemoglobin levels were low at 7.5 g/dL (12–16 g/dL) with normal mean cell volume. Urine pregnancy test was positive with high serum beta-human chorionic gonadotropin (hCG) 6764 IU/L (normal range <7 IU/L). A gynaecology review showed a normal transvaginal pelvic ultrasound with no evidence of a normal or ectopic pregnancy. After resuscitation and transfusion of blood products, she underwent an emergency computed tomography (CT) mesenteric angiogram of abdomen and pelvis as shown on Figure 1. The CT mesenteric angiogram showed an avidly enhancing small bowel nodule in the jejunum, with active extravasation of contrast suggestive of ongoing bleed. There were also incidental pulmonary nodules suggestive of metastatic nodules. Selective coil angioembolization of a mid-jejunal branch of the superior mesenteric artery performed until haemostasis achieved (Fig. 2). Postangioemobolization, she was monitored in the high dependency unit. She remained well with no evidence of re-bleeding or bowel ischaemia. The patient's old medical records were retrieved and it revealed that the reported 'miscarriage' was a hydatidiform mole. In view of her current clinical picture of a high beta-hCG, small bowel nodules with pulmonary metastasis, the diagnosis of a gestational trophoblastic disease from a previous molar pregnancy, with progression to metastatic choriocarcinoma was made. She was then treated with systemic chemotherapy. A follow up CT scan of thorax, abdomen and pelvic done 3 months after chemotherapy showed smaller pulmonary nodules (Fig. 3) and the beta-hCG level normalized. Choriocarcinoma is an uncommon aggressive malignant neoplasm of gestational trophoblastic disease (one in every 20 000–40 000 pregnancies). Diagnosis of metastatic choriocarcinoma may be made based on a raised serum beta-hCG after a molar pregnancy and the presence of radiological evidence of metastases when other aetiologies of a high beta-hCG have been excluded. Unlike other solid tumour, a tissue diagnosis is not required prior to treatment. Biopsy is not recommenced due to the vascularity of choriocarcinoma and the associated risk of excessive bleeding. It commonly metastasizes to the lung (80%), vagina (30%), pelvic cavity (20%), liver and brain (10%). There are a few reports on metastasizes to the gastrointestinal tract (<5%), most commonly to the jejunum, followed by the duodenum and ileum. Affected patients may present with occult or gross bleeding. Patients with jejunal choriocarcinoma can also present with intestinal intussusceptions or perforation.


MONILETHRIX IS AN UNCOMMON DISEASE first described in 1879 by W. G. Smith of Dublin and by Luce in France. It is characterized by a peculiar beading of the hair and an associated keratosis follicularis. The onset is gradual, being first noticed a few weeks or months after birth when the normal hair is replaced by moniliform hair. In a few of the reported cases the onset was much later. The first signs of disease were discovered in the patient described by Ruggles (1900) at 3 to 5 years of age, in Francis's patient at 15 years, and in the patient of Gilchrist (1898) at 17 years. In the family reported by Hanhart (1955), where the disease is thought to be due to a recessive gene, it seems to have started in one member relatively late, probably in his early twenties. The hair may be abnormal over the entire scalp, but more often only a portion is affected, usually the occiput. In some cases the hair of the eyelashes, eyebrows, axilla, pubis, trunk and extremities may be altered in the same way. When the entire scalp is affected the patient may be totally bald or may have a sparse covering of short broken hair. When monilethrix is local the more normal hair is frequently short and thin. Keratosis follicularis may develop before or shortly after the appearance of abnormal hair. It may involve the scalp, neck and limbs, and does not necessarily coincide with parts covered by moniliform hair. The abnormal hairs usually show constrictions at regular intervals, but some are atrophic over their whole length. They are very brittle and may break off at a constriction after reaching a length of about one to three centimeters. Microscopically the spindle-shaped parts of the hair are normal, but at the constrictions the cortex is reduced and the medulla usually absent (figure 1). The keratosis is not the cause of the beading, as moniliform hairs may grow where there is no keratosis and the hairs are abnormal before they emerge from the follicles. Affected individuals are usually healthy and of good physique. A few associated defects have been described (Sabouraud, 1892; Rosenthal and Speiregen, 1928; Racz and Turi, 1954), but at least some of these are probably coincidental. Cockayne (1933) tabulated the cases then available and concluded that the condition was due to a dominant gene without sex limitation. In some reported families penetrance of the gene appears to have been incomplete, but it should be noted that none of the apparent carriers were thoroughly examined by the original author. Two alleged carriers occurred in our family, and we shall discuss the question of incomplete penetrance further.


This paper starts from the premise that syntactic structure serves as a mechanism to constrain the possible interpretations of the elements it brings together.1 That is, assigning a particular set of elements into a syntactic configuration does not just link them together for any old combined interpretation, but does so in a structured way that systematically excludes certain ranges of possible collective interpretations, and permits still others. The simplest examples are found in isolating languages like Mandarin or English, where lexical elements surface in collocation rather bare of functional morphology, such that they can be read off into a variety of possible syntactic structures, and from that, an equal variety of semantic interpretations. Hence for example the English √root run, which is on its own surface-ambiguous for unergative, transitive-causative, and middle readings; for comparable examples in Mandarin, see Lin 2001. Such cases are something of a red herring, however. They show less a lack of functional structure than a lack of overt functional morphology. And of course many polysynthetic languages (among others) systematically disallow such surface alternations, overt morphology being always or typically used to manifest these contrasts. The more telling cases instead are the rich possible range of thematic relationships that the nominal elements of lexical compounds can hold with the rest of the structure: basic themes, locatives, and instrumentals, to name just a few.


Based on the analysis of the force character in wind flow fields, the similarity of structural wind motion has been studied. Strict conditions related vibration parameters are introduced with which wind motion similarity can be realized when three types of damp exist simultaneously.


Due to global shifts in climate, studies in contrasting conditions of two natural and climatic zones are of particular interest: (1) subzone of mixed and broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, and therefore increase the loss of quality of plant materials. The frequency of occurrence of mycoses in autumn is 2-14 times higher than in spring-summer observations. The activity of phytopathogenic fungi of the genera of Fusarium (the causative agent of fusarium), Puccinia (rust), Phoma (phomosis), Rhizoctonia (scab), Verticillium (tracheomycotic or vascular wilting) increases. Differences in dominant micromycetes from the point of view of geography were determined: zone 1 (forest) - Alternaria spp., Chaetomium spp., Fusarium spp., F. avenaceum (Fr.) Sacc., (Mart.) Sacc., Heterosporium iridis (Fautrey & Roum.) JE Jacques, Phoma spp., Stemphylium spp., Verticillium spp.; zone 2 (steppe) – Alternaria spp., Botrytis spp., Cladosporium spp., Fusarium avenaceum, Fusarium spp., Peronospora spp., Phoma spp., Pullularia spp., Septoria spp. Screening of pesticides (biological fungicides) showed the effectiveness of preparations based on Pseudomonas fluorescens, Bacillus subtilis or Streptomyces griseus in limiting the growth of the mycelium of phytopathogenic fungi.

During 1971 and 1972, 4,400 adults of Rhinocyllus conicus Froelich were introduced into southern California from Italy for the biological control of milk thistle [Silybum marianum (L.) Gaertner]. These flowerhead-infesting weevils were colonized at nine, and successfully established at five, widely separated locations. Field data on the incidence and increase of R. conicus at colonization sites are presented. Biotic mortality factors reported for R. conicus in southern California include predation of eggs by ladybird beetles (Hippodamia sp.) and of adults by snakeflies [Raphidia (Agulla) adnixa Hagen] and spiders, destruction of weevils in flower-heads consumed by cattle and rodents, and larval and pupal parasitism by pyomotid mites.

DOI: 10.1002/aenm.201901124 to the current multifunctional sensors. On the other hand, IoTs also expects the sensors can continuously work for long hours without maintenance.[10] The energy harvesting technologies that can provide continuous power supply[11–16] and selfpowered sensors that can directly transfer the detect information into electrical signals even without power[7,17,18] are the idea approaches to meet the requirements. Based on the triboelectric effect and the electrostatic induction, triboelectric nanogenerators (TENGs) invented by Wang and co-workers[19] have a few remarkable advantages, such as flexibility, light weight, easy integration. They have demonstrated to be an applicable solution for both self-powered sensing and energy harvesting.[20–23] Specifically, the force,[24] speed,[25,26] acceleration,[27,28] direction,[29] and angle[30] all can be measured by the TENG. And the TENG also has been successfully used to build multifunctional sensors.[31–33] Based on the TENG, a real multifunctional sensor enabled by magnetically regulated TENG has the capacity to measure motion parameters, including acceleration, speed, and direction of rotary and linear motions.[33] Unfortuately, six output channels increace the complexity of the sensor and the surface contact friction limits its sensitivity. Moreover, for enhancing the output performance of the TENG, many works are focused on the selection and the surface nanocrystallization of friction materials, which both are relatead to the triboelectric effect.[34–36] However, about the electrostatic induction, there also need some theoretical guidances of the electrode materials selection. In this paper, inspired by the movement statement of a magnetic cylinder placed beside a fixed magnetic cylinder, a cylindrical self-powered multifunctional sensor (MS) with a translational-rotary magnetic mechanism is presented, which is capable of detecting acceleration, force, and rotational parameters. The MS is composed of a translational-rotary magnetic mechanism, a TENG module, and an acrylic shell. The translational-rotary magnetic mechanism is a low damping magnetic cylinder (MC) rotating around a fixed circular tube, which is embedded by a magnetic disk (MD). The sensitivity of the MS can be adjusted by changing the distance between two magnets. The TENG module consists of the MC and a friction layer that is a polytetrafluorethylene (PTFE) film with two interdigitated electrodes (IEs) bonded on the surface of the tube. The MS can transform a translational motion into a swing motion or a Triboelectric nanogenerators with a large number of desirable advantages, such as flexibility, light weight, and easy integration, are unique for sensor design. In this paper, based on the triboelectric nanogenerator (TENG), a cylindrical self-powered multifunctional sensor (MS) with a translationalrotary magnetic mechanism is proposed, which has the capacity to detect acceleration, force, and rotational parameters. The MS can transform a translational motion into a swing motion or a multicircle rotational motion of a low damping magnetic cylinder around a friction layer and hence drives the TENG to generate voltages output. For enhancing the output performance of the TENG, an electrode material with small work function, low resistance, and suitable surface topography is the best choice. According to the structure characteristic of the translational-rotary magnetic mechanism, the MS can easily respond to a weak striking and can be used to measure the rotational parameters without the need of coaxial installation. Based on the MS, some applications are established, for example measuring the punch acceleration of a boxer, the hitting force and swing angle of golf club, which demonstrate the feasibility and efficiency of the MS and exhibit that the MS could find applications in sports.

The fractional differential equations (FDEs) are ubiquitous in mathematically oriented scientific fields, such as physics and engineering. Therefore, FDEs have been the focus of many studies due to their frequent appearance in several applications such as physics, engineering, signal processing, systems identification, sound, heat, diffusion, electrostatics and fluid mechanics, and other sciences. The perusal of these nonlinear physical models through wave solutions analysis, corresponding to their FDEs, has a dynamic role in applied sciences. In this paper, the exp-function method and the rational

 -expansion method are presented to establish the exact wave solutions of the space-time fractional Drinfeld–Sokolov–Wilson system in the sense of the conformable fractional derivative. The fractional Drinfeld–Sokolov–Wilson system contains fractional derivatives of the unknown function in terms of all independent variables. This system describes the shallow water wave models in fluid mechanics. These presented methods are a powerful mathematical tool for solving nonlinear conformable fractional evolution equations in various fields of applied sciences, especially in physics.


Photoluminescence (PL) measurements due to temperature and excitation power were carried out in as function of sample containing a In0,53Ga0,47. As layer, grown by Molecular Beam Epitaxy on an InP substrate. The origins of the several luminescence processes observed at low temperature were determined by studying their different behaviors with increasing temperature and excitation power and by comparing the results with the data found in the literature. The following transitions have been identified: one transition involving localized excitons and two transitions involving acceptor impurities. A review of the main works published in the literature related to the optical transitions observed at low temperature in InGaAs/InP is also presented.

BACKGROUND: Stroke is responsible for the largest proportion of neurological disorders causing a significant morbidity. Gamma-glutamyl transferase (GGT) enzyme has an active involvement in atherosclerosis through its role in oxidative and inflammatory mechanisms. Recent evidence suggests that serum GGT is related to the risk and prognosis of cerebrovascular diseases. METHODS: A total of 200 patients (100 with acute ischemic stroke and 100 without stroke) were recruited from various medical wards and medical intensive care unit. Categorical variables were compared between two groups using Chi-squared test and odds ratio (OR). Independent sample t-test was used to see to compare mean GGT level of stroke patients with control. RESULTS: There was no statistical difference with respect to distribution of age groups (χ2 = 1.25, P = 0.741) and gender (χ2 = 2.678, P = 0.1018) between cases and controls. Mean age of stroke patients (mean [M] = 61.7, standard deviation [SD] = 13.8) did not differ from controls (M = 62.2, SD = 13.6), P = 0.80. The odds of suffering from diabetes were significantly higher in stroke patients than cases (OR = 2.25, P = 0.005). Independent sample t-test found a significant difference in serum GGT level between cases (M = 57.47, SD = 11.8) and control (M = 41.72, SD = 7.5), P ≤ 0.0001. CONCLUSIONS: Serum GGT was significantly higher in stroke patients than age-sex-matched nonstroke patients. Association remained significant in stroke patients irrespective of age, gender, and other risk factors. Stroke patients with diabetes, hypertension, dyslipidemia, obesity, and smoking had higher level serum GGT level than those without these risk factors. Prospective cohort studies can further explore the potential of GGT as a predictor of acute ischemic stroke.


The double linearization theory is extended to a three-dimensional straight cascade between parallel-plane end walls operating at supersonic axial velocity. Numerical examples are presented to show unsteady aerodynamic responses and flutter boundaries in correlation with cascade parameters. The three-dimensional effects are evaluated by comparing them with the strip theory predictions. To attain a large steady loading on the stability boundary of the first bending vibration, it is advantageous to design blades with angle of attack and camber decreasing from hub to tip. The three-dimensional effects are small, and the strip theory was found to be a useful method for estimation of the unsteady aerodynamic work of the three-dimensional straight cascade.

In continuing investigations of brown tree snake, Boiga irregularis, attraction to carrion odor, we hypothe- sized that the attractiveness of live or dead and visually apparent or concealed lures varies seasonally. We determined that lure condition (live or dead mouse lures) and sensory cues (visually apparent or concealed lure) interact among wet and dry seasons. Concealed carrion lures were more effective during the dry season than the wet season, but the effectiveness of live mouse lures showed less seasonal variability. We identified weather variables that covary with ob- served seasonal trends in capture rates and investigated the influence of recent feeding on snake response to lures. Data suggest that live mouse lure capture rates correlate with wind and dead mouse capture rates correlate with rainfall. Re- cently fed and satiated snakes were not less responsive to lures but were less active than unfed snakes. Snakes held for over 2 years were less responsive than recently captured snakes. More intensive studies will be required to determine cause-and-effect relationships between lure type, seasonality, and snake behavior.

Healthy lifestyles, victory gardens, and Blue Zones are familiar terms to most, and each incorporates a holistic approach to human well-being. The therapeutic and nutritional benefits of gardening have long been recognized. After World War I, many service members were treated using horticulture therapy methods. During the early stages of the COVID-19 pandemic, many individuals and families turned to gardening as a source of supplemental food and physical and emotional wellness. The benefits of gardening, however, go beyond promoting physical health; they promote a healthful lifestyle. This is a holistic term which encompasses several dimensions of your life, including the spiritual, emotional, physical, intellectual, financial, social, and environmental dimensions (Lynch et al., 2021). This publication is a basic guide to incorporating gardening into your lifestyle including planning, planting, and harvesting considerations.


A new nano conducting polymer composite containing natural rubber (NR) filled with Bi-based superconductor (BSCCO) nanoparticles was successfully fabricated using a traditional milling rubber technique. The scanning and transmission electron microscopic (SEM, TEM) studies provide information on quality of these samples and the uniform distribution of BSCCO particles within NR matrix. The electric conductivity and dielectric measurements have been carried out in the frequency range of 50 Hz-1 MHz and temperature range of 298-428 K. The measured impedance data were analysed on complex plane and the dc (bulk) as well as ac conductivity were obtained. Studies of dielectric constant as a function of frequency at different temperatures revealed that the compounds do not have any dielectric anomaly in the studied frequency and temperature range. The enhancement of the dielectric properties of nanocomposites makes it feasible as co-fired dielectric component devices.


Osteoporosis (OS) develops without any pain or symptom, and it is usually identified when the weakened bone causes fracture. To overcome this issue, measuring bone density (BMD) helps to identify osteoporosis and its conditions. It was identified that when the level of anti-cyclic citrullinated
 peptide (anti-CCP) increases, values of BMD were decreased. This research was focused to quantify the level of anti-CPP on nanomaterial modified polystyrene ELISA substrate. ELISA wells were modified into amine-carbon nanofiber and then glutaraldehyde used as a linker to attach CCP. Anti-CCP
 antibody level was quantified on PS plate by secondary-antibody conjugated horseradish peroxidase. Carbon nanofiber improves the immobilization of CCP on PS well and attract higher number of anti-CCP antibody, which helps to reach the limit of detection at 10 pg/mL, which was four times lower
 limit of detection with conventional ELISA (40 pg/mL). Further, specific experiment was conducted with serum spiked anti-CCP antibody shows the absorbance increment in all the concentrations of anti-CCP antibody and control performances with relevant molecules did not increase the absorbance
 level confirms the selective and specific detection. This carbon nanofiber modified ELISA well quantifies anti-CCP level and helps to identify the condition of bone for diagnosing osteoporosis.

The American public seems convinced that its schools have deteriorated. State legislatures and institutions of higher education have acted to stem this deterioration by mounting costly programs of educational reform. Yet there is reason to suspect that the results of these programs will be disappointing. It is not because the programs are ill conceived or underfunded. Rather, it is because the alleged deterioration itself is ill conceived. What is wrong with schools is not what legislators and university officials think is what is wrong. Necessarily, then, current reforms are irrelevant to the settings they are intended to correct. The deterioration is said to have affected the academic quality of secondary schools. The evidence for this is usually presented in terms of declining scores on Scholastic Aptitude Tests and declining enrollments in academic courses of study. One of the aims of this article will be to show that these indicators of decline are ambiguous at best, and are better interpreted as symptoms of a more serious kind of decline in the schools. In an effort to stem the apparent deterioration in secondary schools, policymakers have initiated a number of programs for reform. The most popular of these have been minimum competency testing as a condition for graduation from high school and the requirement of additional academic courses as a condition for admission into college. A second aim of this article will be to show that these programs cannot reasonably be expected to bear fruit. They will make a difference, of course. They will divert funds from other, more promising educational programs, and they will add to the burdens and frustrations already experienced by those who work and study in secondary schools. What may be the greatest obstacle to the reform of secondary education is the failure to understand what is ailing the schools. I will try to establish a better understanding by showing that the alleged deterioration in high schools is largely a fabrication of the mass media. The media, in turn, have been supplied by colleges and universities with misleading information about


the sample possibly due to a relative non-existence of Dalit–upper caste divide in the public psyche of West Bengal. Third, to make it a more effective campaign material, while it rightly reports a number of stories of Dalit resistance, the book could also consider some progressive tales of Dalit–upper caste amity which are perhaps available in different regions of this vast country. Finally, in future editions of this important text, some proofreading errors need to be corrected.

Didymus' commentaries on the comic playwrights and his Comic Vocabulary responded to the interests of the readership of Attic comedy primarily in two ways: by summarizing the opinions of previous scholars and by offering a wide range of explanations, useful also to less specialized readers. Although his exegesis of comedy is now preserved only through quotations (mainly in the scholia to Aristophanes), it is still possible to identify the main features and interests of Didymus' interpretative work and highlight its relevance for both ancient and contemporary readers of Greek comedy.


Ciputat Market is a regional scale traditional market in South Tangerang. In 2002, the construction of shopping centers and modern shops began to grow slowly in the area of South Tangerang. The operation of shopping centers and modern shops are getting closer and outreach to the people, on the one hand it has made it easier for people to buy goods of daily needs, but on the other hand it can impact the development of the traditional market, because consumers have many choices places to shop.

An efficient, economical procedure for the cleavage of allyl aryl ethers using a catalytic amount of iodine in dimethyl sulphoxide gives corresponding alcohols or phenols in high yields under mild condition. The reaction can be performed in air without loss of variety of oxidisable fuctional groups. Allyl ether of phenols is selectively deprotected in preference to alcohols. The reaction is highly regioselective and chemoselective.


Abstract Research has suggested that grandparents caring for grandchildren experience both psychological gains and loss. Less clear is what happens to these grandparents after they exit from the caregiving role. This study used the Health and Retirement Study (HRS) 2010 to 2014 data to examine the effects of transitioning out of caregiving on the psychological well-being of grandparents. Psychological well-being was measured by the Positive and Negative Affect Schedule. We defined caregiving grandparents as grandparents who provide 100+ hours of care per year to their grandchildren. In the first wave, 8,278 respondents in the HRS were identified as caregiving grandparents. Among them, 3,914 continued to be caregivers and 4,364 transitioned out of the caregiving role by indicating they are no longer providing care in the second wave. Grandparents who transitioned out of caregiving are more likely to be older in age, less educated and not married. Linear regression analysis was conducted to compare the two groups (continuing vs. exiting caregiving) on positive and negative affect, controlling for the first wave's measures of the dependent variable, sociodemographic characteristics and health status of respondents. Results show that grandparents who continued caregiving had less decline in positive affect than grandparents who transitioned out of caregiving (b = -0.05, SE = 0.02, p<0.01), adjusting for covariates. But they were not significantly different in negative affect. These findings indicate that older adults may have fewer sources of joy after exiting the role of caregivers of their grandchildren.


The lack of services and accommodations that have been identified as efficacious to support orientation and mobility for students with visual impairments within the higher education setting is related to the environment failing to appropriately address the unique needs of this population. Given that institutions of higher education have historically been designed without consideration of students with disabilities, being able to navigate a college campus in a manner similar to students without disabilities provides distinct advantages. An evaluation was undertaken on BeAware, a location-based navigation smartphone app for individuals with visual impairments, to assess the efficacy of the app as well as participants' perceptions of access to and acceptance within the university as a result of its use. All aspects of the study were conducted on campus, and purposive sampling identified students to participate. Data were collected through the use of a multiple-baseline across behaviors design to test participants' independent mobility, followed by qualitative interviews. Findings suggest that BeAware is an effective method for promoting independent mobility for students with visual impairments. Participants had positive perceptions of the impact the app had on access to, and acceptance within the higher education setting. Given the nature of most of the research in this area, these findings provide valuable information to app developers and higher education leaders in supporting accessibility and access through the provision of needed accommodations.


A series of 4,6-dibenzhydryl-2-[(arylimino)methyl]phenol derivatives (L1–L6) and their nickel complexes (Ni1–Ni6) were synthesized and characterized by spectroscopic and elemental analyses. Molecular structures of Ni3 and Ni6 were further confirmed by single-crystal X-ray crystallographic studies. When activated with ethylaluminium sesquichloride (EASC), all nickel pre-catalysts displayed good catalytic activity (up to 2.89 × 106 g mol−1(Ni) h−1) for ethylene dimerization. Furthermore, these nickel complexes showed high activity for norbornene polymerization in the presence of MAO.


Phospholipase C (PLC) β4, one of the four isoforms of PLCβs, is the sole isoform expressed in the mouse ventral posterolateral thalamic nucleus (VPL), a key station in pain processing. The mouse thalamus also has been shown to express a high level of metabotropic glutamate receptor type 1 (mGluR1), which stimulates PLCβs through activation of Gαq/11 protein. It is therefore expected that the thalamic mGluR1-PLCβ4 cascade may play a functional role in nociceptive transmission. To test this hypothesis, we first studied behavioral responses to various nociceptive stimuli in PLCβ4 knock-out mice. We performed the formalin test and found no difference in the pain behavior in the first phase of the formalin test, which is attributed to acute nociception, between PLCβ4 knock-out and wild-type mice. Consistent with this result, acute pain responses in the hot plate and tail flick tests were also unaffected in the PLCβ4 knock-out mice. However, the nociceptive behavior in the second phase of the formalin test, resulting from the tissue inflammation, was attenuated in PLCβ4 knock-out mice. In the dorsal horn of the spinal cord where PLCβ1 and PLCβ4 mRNAs are expressed, no difference was found between the wild-type and knock-out mice in the number of Fos-like immunoreactive neurons, which represent neuronal activity in the second phase in the formalin test. Thus, it is unlikely that spinal PLCβ4 is involved in the formalin-induced inflammatory pain. Next, we found that pretreatment with PLC inhibitors, mGluR1 antagonists, or both, by either intracerebroventricular or intrathalamic injection, attenuated the formalin-induced pain behavior in the second phase in wild-type mice. Furthermore, activation of mGluR1 at the VPL enhanced pain behavior in the second phase in the wild-type mice. In contrast, PLCβ4 knock-out mice did not show such enhancement, indicating that mGluR1 is connected to PLCβ4 in the VPL. Finally, in parallel with the behavioral results, we showed in an electrophysiological study that the time course of firing discharges in VPL corresponds well to that of pain behavior in the formalin test in both wild-type and PLCβ4 knock-out mice. These findings indicate that the thalamic mGluR1-PLCβ4 cascade is indispensable for the formalin-induced inflammatory pain by regulating the response of VPL neurons.


The application of the culture-of-poverty concept to family planning is reviewed. Two approaches to program development are contrasted: accessibility versus cultural-motivational. Experience appears to support the accessibility approach which seeks to create services where none exist or to remove obstacles which make services inaccessible (distance crowding eligibility and fee practices scheduling lack of information and depersonalized delivery). Yet the cultural-motivational view dominates the thinking of many health and welfare professionals and is employed to rationalize slow progress. This anomaly is analyzed as an example of the resistance of institutions to change and in terms of its historical antecedents in upper-class biases about lower-class fertility. The implications for public policy are explored particularly the potential use of the culture-of-poverty concept to justify selective compulsory fertility control if health and welfare agencies continue to lag in developing voluntary programs.

It is not often that a text book can provide an enjoyable read but Hajek's Natural enemies: an introduction to biological control certainly delivers. This work fills a niche, giving a muchneeded update to previous works and providing a more affordable and concise alternative to the 1999 Handbook of biological control: principles and applications of biological control (edited by Bellows & Fisher) and the subsequent 2004 edition of Jervis's Insects as natural enemies: a practical perspective . It succeeds in bringing together the various fields of study relating to biological control, providing the key reference material supporting what must be an excellent taught course from which it presumably grew. In her précis, Hajek states that the book is intended for undergraduate students and others wishing to learn the basics of biological control, and I think that she has surpassed this goal, often managing to provide a level of detail also suitable for post-graduate study. Nineteen chapters deal with all aspects of the use of natural enemies for pest management in a comprehensive and well-supported way, which moves from history to theory and practicalities in a very logical and effective way. It is clear that Hajek has called upon highly appropriate experts in each field to ensure thorough and up-to-date coverage of each subject area. The acknowledgements read like a Who's who of biocontrol. Each chapter is amply augmented with figures, case studies and further reading, in keeping with a quality textbook. I was particularly interested in the profiles of the founders of the disciplines, which set the scene very well, but it is the quality of the very informative figures that distinguishes this book. Virtually every photograph is of an enviably high standard and the original artwork, credited in the main to Alison Burke, is superb, especially for a book at this price. The collation of information into concise graphs and tables is also impressive and useful, as are the clear descriptions and language used. As the author points out in chapter 4, there is some confusion with the terminology used in biological control and I'm afraid this still remains despite the author's attempts to clear things up, using the suggestions she proposed with coauthors in 2001 (Eilenberg et al ., 2001). Many biocontrol practitioners still use 'inoculative' and 'classical' interchangeably and rely on 'inundative' to refer to those releases of biocontrol agents that are not expected to persist. 'Augmentation' is often assumed to mean increasing those natural enemies already present or naturally occurring. This is especially important if all biocontrol disciplines are to be encompassed. Having said this, a student needs clarity in definitions when differences of opinion exist, and this has been achieved in the book. Hajek has managed to use very up-to-date literature; the reference list is comprehensive for most subjects and includes some that I will be adding to my collection. Her experience at two of the major centres of biological control shines through and it is only in areas outside her field that some weaknesses are visible. The book is clearly very insect-focused, which is arguably a reflection of history and the available literature. As a weed biocontrol practitioner, I am of course a little biased, but to dedicate only six pages of a 378-page book to classical biocontrol of weeds with fungi seems a little frugal. This field is certain to grow and should perhaps have been given more consideration. It is good that Hajek has not avoided the more controversial issues surrounding biocontrol and she reviews these in a responsible manner, especially in chapter 18 on safe biological control. The challenges facing biological control are legion, and controversy and public misconception are certainly high on the list. Hopefully this book will be used to provide a more balanced picture. Another very positive aspect of the book is the thorough consideration of the ecology of biocontrol at every level. Now that biological control is becoming more front line and less the forgotten alternative to chemicals, thanks to chemical reduction policies and a growing biocontrol success rate, ecologists are showing more and more interest. I am often disappointed to see how divorced these two disciplines can be in practice, especially given that one is so clearly based on the other, and I hope that in future, researchers who use Hajek's text book will be more inclusive as a result. Without doubt Hajek has produced an excellent textbook on a very broad subject, which is not only thoroughly researched, wellillustrated and impeccably edited, but most important for this genre it is very readable. Natural enemies: an introduction to biological control is an excellent, high-quality publication at an affordable price and should appeal to both students and scientists with any interest in pest management, biogeography, ecology and, of course, biological control.


To obtain the optimism co-incubation time of boar sperm with DNA and set up the technique platform of swine sperm-mediated gene transfer,the Real time quantitative PCR,fluorescence microscope imaging and regular semen quality analysis were applied to detect the influence of incubation time of sperm with DNA on viability,motility,transfect efficiency,and the amount of adsorbed DNA and internalized DNA of sperm.The result revealed that,after 15,30,60,and 90 min co-incubation of the parceled and labeled DNA with sperm,the sperm motility and viability decreased extremely significantly with the increase of incubation time(P0.01),while the transfect efficiency increased extremely significantly(P0.01) or significantly(P0.05),as well as the amount of adsorbed DNA and internalized DNA increased,However,there was no difference among incubation times(P0.05) after 30 min incubation.In addition,compared with the increase of transfect efficiency of sperm,the decrease of motility and viability of sperm relatively was more obvious with the increase of co-incubation time.Overall,considering the parameters of motility,viability,transfect efficiency and the amount of adsorbed DNA and internalized DNA of sperm,the best co-incubation time of swine sperm with foreign DNA is 30 min.

Political, social, and cultural controversies are the main fodder of staff cartoonists at newspapers. From the serious to the silly, newspaper cartoonists are expected to comment on whatever happens to be in the news cycle on any day. This commentary creates both ephemera and historical evidence of events and their effects on society. This article investigates an incident at a jazz concert in Auckland in 1952 at which the musicians were charged with abusing the new Steinway grand piano and the following controversy about the jazz musicians' use of town hall facilities. From this incident New Zealand Herald cartoonist Gordon Minhinnick responded with a cartoon and a comic strip about the debate. By examining Minhinnick's contributions via the lens of cultural history we can apprehend the shape of this dispute (politically and culturally), how it impacted Auckland society, and also gain a sense about how jazz was perceived by society at large at that time. We can also see how Minhinnick used the debate to illustrate other important political issues facing Auckland at the time.


Through a large number of field investigations in the delta oasis of Weigan and Kuqa rivers in northern margin of Tarim Basin in Xinjiang,the characteristics of soil salinization(above: conductivity,salinity,total dissolved solids,etc.) in different spatial changes were analyzed.Using the analysis of correlation and regression to study the relations between the soil compositions.The results showed that the content of salt,conductivity and TDS in the 0-10 cm,10-30cm,30-50cm have strong variability,the pH value in all layers are weak variability,and the content of water are middle variability.The correlation between salt content and conductivity and TDS are positive significant,water content and salt content is little significant,pH value and salt content is a significant negative correlation.Regression analysis indicted: the level of soil salinization is indicted by conductivity and TDS,pH value and water content have no relationship with soil salinization.


The climate sensitivity of the Earth and the radiative climate feedback both change over time due to a so-called "pattern effect", i.e., changing patterns of surface warming. This is suggested by numerical climate model experiments. The Atlantic Meridional Overturning Circulation (AMOC) influences surface warming patterns as it redistributes energy latitudinally. Thus, this ocean circulation may play an important role for climate-feedback change over time. In this study, two groups of members of the Coupled Model Intercomparison Project (CMIP) phases 5 and 6 abrupt4xCO2 experiment are distinguished: one group showing weak and the other strong feedback change over time. It is found that both groups differ significantly in the AMOC response to 4xCO2. Therefore, experiments with a slab-ocean model (SOM) with quadrupling of the CO2 concentration are performed where the AMOC change is mimicked by changing the ocean heat transport. It is found that in the Northern Hemisphere extra-tropics the CMIP model group differences can be qualitatively reproduced by the SOM experiments, indicating that the AMOC plays an important role in setting the surface warming pattern. However, in the tropics and especially in the Southern Hemisphere other explanations are necessary.


Sediment deposition caused by debris flows and floods is an important process controlling the evolution and regression of lake, and even a pervasive environmental problem. Qiong Lake is regards as a "bright phearl of the altiplano" in the Yunnan Plateau, and because debris flows construct a vital links between mountain slope and Qiong Lake, so the debris flows drove by rainfall will control the evolution rule of rift lakes. Based on the data of lake shorelines of Qiong Lake, it was found that the shoreline was push forward by 665 m since 1998. In addition, in the recent 30 years, turbidity current deposits have generated underwater levee and other landscapes in the deep water area of Qiong River. This paper has analyzed the matter migration process induced by debris flows, and presented the regime change pattern of debris flow along river channel and corresponding mechanical mechanism, mainly revealed the submarine transportation and deposition pattern of debris flow. The above studies provide a helpful way of comprehending the formation mechanism of turbidity flow induced by debris flow, and the transportation pattern. Based on severe sediment deposition catastrophes in this kind of rift lakes from debris flows and floods, disaster mitigation must be planned and appropriate engineering countermeasures put in place as soon as possible.


Centrifugal pump is the most important equipment and extensively used in all industrial plants where fluid handling is involved. The operation of a centrifugal pump is
solely depends on its own flow-head characteristic curve. The operating point is always where the pump curve meets the flow-head system resistance curve of pumping system
that particular pump is handling. Hence the importance of using those curves and the calculation to determine the operating point parameters cannot be overemphasized.
Selecting the right pump for any application and the right manufacturer are two of the most important decisions that will have to make for the life of the product. Poor pump
selection is the major contributor to the failure of processes that demand reliable fluid movement. In this project pump performance is investigated with certain experiment like series and parallel and result will be analyzed by plotting graph flow capacity against
head to calculate pump efficiency.


The paper presents the idea, design and performance evaluation of a low-cost Attitude and Heading Reference System (AHRS). It is based on an Inertial Measurement Unit (IMU), being a single sensor pack that provides all the raw data required to feed the designed filter. An extension of a complementary filter in form of feedback control system with PI controller, called 3D complementary filter provides attitude estimates in Euler angles representation. A developed algorithm of filtering and data fusion poses small computational requirements for the designed low-power embedded hardware. Test were performed based on the sensor model and next using a real IMU. Experimental results obtained by means of rapid prototyping of designed filtering algorithm in different operating states are presented and discussed.

SUMMARY: An unusual case report is described here, of a young man who developed a pseud oaneurysm of the left Dorsalis Pedis Artery (DPA) ten years earlk?r, following a blunt injury. He sustained a recent injury to the same foot following which, the lump became enlarged and painful. Doppler flow studies and angiography confirmed the diagnosis and revealed the causative ostium through which this partially thrombosed aneurysm had arisen. Successful aneurysmectomy and end-to-end LSV bypass graft surgery was followed by complete recovery. Discussion: This patient's aneurysm was partially thrombosed. A properly performed real time B mode Ultrasound scan can reliably show intrinsic thrombi, the thickness of the aneurysm a! wall and the diameter of the functional lumen (1).Vigorous manual compression of an aneurysm may dislodge intrinsic thrombi distally (3). Traditional demonstration of the "sign of compressibility" should be superseded by non-invasive doppler assessment.Our patient was in pain most certainly due to a variety of reasons. Compressive neuropathy (18), distension of the deep fascia, irritation of the muscle sheath, movement of the aneurysm due to contraction of the involved and adherent muscles etc., can all have been the causes of this local pain.

We present an analysis of a sample of 69 local obscured Swift /BAT active galactic nuclei (AGN) with X-ray spectra from NuSTAR and IR spectral energy distributions from Herschel and WISE . We combine this X-ray and IR phenomenological modeling and find a significant correlation between reflected hard X-ray emission and IR AGN emission, with suggestive indications that this correlation may be stronger than the one between intrinsic hard X-ray and IR emissions. This relation between the IR and reflected X-ray emission suggests that both are the result of the processing of intrinsic emission from the corona and accretion disk by the same structure. We explored the resulting implications on the underlying distribution of covering fraction for all AGN, by generating mock observables for the reflection parameter and IR luminosity ratio using empirical relations found for the covering fraction with each quantity. We find that the observed distributions of the reflection parameter and IR-to-X-ray ratio are reproduced with broad distributions centered around covering fractions of at least ∼ 40 − 50%, while narrower distributions only match our observations when centered around covering fractions of ∼ 70 − 80%. Our results are consistent with both independent estimates of the covering fractions of individual objects and the typical covering fraction obtained based on obscured fractions for samples of AGN. These results suggest that the level of reprocessing in AGN, including X-ray reflection, is related in a relatively straightforward way to the geometry of the obscuring material.

While respect for diversity was a theme 'on the margins' of the debates on early childhood education in the 1980's, it is at the core of many concerns today. There is an emerging consensus on how to address issues of diversity in early childhood education theory, policy and practice. Yet, it is precisely this consensus that may be worrying. Inspired by post-foundational theory, I argue that dissensus and disagreement are not only inevitable, but are also necessary to foster respect for diversity, not as tolerance towards those who deviate from the norms, but as a deconstruction of the norms that create deviations. Key words : democracy, political, early childhood and diversity

Objective To explore the curative efficacy of different doses of ondansetron in different ways in the prevention of postoperative nausea and vomiting in patient-controlled epidural analgesia. Methods Total 120 patients who underwent general surgery were divided into two groups in a random double-blind method with 60 for each group: experimental group and control group. The experimental group was given intravenous ondansetron 8mg,and the nausea and vomiting incidence was observed 24h after surgery and the nausea and vomiting extent was scored. Ondasetron was not given to the control group. Results The heart rate and blood pressure were kept stable in both groups in 24h after operation. Respiratory depression did not occur in all patients.The incidence of nausea and vomiting was significantly lower in the experimental group than that in the control group(P0.05). Conclusion Intravenous ondansetron 8mg is more effective to release postoperative nausea and vomiting due to general anesthesia.


We propose a planning method for offshore wind farm electrical collector system (OWF-ECS) with double-sided ring topology meeting the "N-1" criterion on cable faults, in which the submarine cables layout of OWF is optimized considering cable length and power losses. The proposed mixed-integer quadratic programming (MIQP) model is based on the Capacitated Vehicle Routing Problem (CVRP) formulation and power network expansion planning, which could approximate the power losses in OWF-ECS. In addition, cross-avoidance constraints are proposed to avoid crossing cables, and the minimum k-degree center tree model is included to improve the convergence. Case studies on OWFs with 30 and 62 WTs demonstrate the effectiveness of the proposed method. Considering the potential outage cost in the radial topology, the total cost of the planning result is reduced by up to 25.9% with reliability improvement. The cable investment is reduced by 4%∼8% with the proposed method compared with conventional heuristic methods and Google OR-tools. The proposed method/model can also achieve acceptable computation efficiency and OWF-ECS planning results with good optimality. Moreover, it could be solved by modern commercial solvers/optimization software, thus it's easy to use even for large-scale OWF.

Neutron stars spinning at moderate rates (∼300–600 Hz) become oblate in shape and acquire a nonzero quadrupole moment. In this paper, we calculate the profiles of atomic features from such neutron stars using a ray-tracing algorithm in the Hartle–Thorne approximation. We show that line profiles acquire cores that are much narrower than the widths expected from pure Doppler effects for a large range of observer inclinations. As a result, the effects of both the oblateness and the quadrupole moments of neutron stars need to be taken into account when aiming to measure neutron-star radii from rotationally broadened lines. Moreover, the presence of these narrow cores substantially increases the likelihood of detecting atomic lines from rapidly spinning neutron stars.

Purpose: At diagnosis, colorectal cancer presents with synchronous peritoneal metastasis in up to 10% of patients. The peritoneum is poorly characterized with respect to its superspecialized microenvironment. Our aim was to describe the differences between peritoneal metastases and their matched primary tumors excised simultaneously at the time of surgery. Also, we tested the hypothesis of these differences being present in primary colorectal tumors and having prognostic capacity. Experimental Design: We report a comprehensive analysis of 30 samples from peritoneal metastasis with their matched colorectal cancer primaries obtained during cytoreductive surgery. We tested and validated the prognostic value of our findings in a pooled series of 660 colorectal cancer primary samples with overall survival (OS) information and 743 samples with disease-free survival (DFS) information from publicly available databases. Results: We identified 20 genes dysregulated in peritoneal metastasis that promote an early increasing role of "stemness" in conjunction with tumor-favorable inflammatory changes. When adjusted for age, gender, and stage, the 20-gene peritoneal signature proved to have prognostic value for both OS [adjusted HR for the high-risk group (vs. low-risk) 2.32 (95% confidence interval, CI, 1.69–3.19; P < 0.0001)] and for DFS [adjusted HR 2.08 (95% CI, 1.50–2.91; P < 0.0001)]. Conclusions: Our findings indicated that the activation of "stemness" pathways and adaptation to the peritoneal-specific environment are key to early stages of peritoneal carcinomatosis. The in silico analysis suggested that this 20-gene peritoneal signature may hold prognostic information with potential for development of new precision medicine strategies in this setting.

Facing the weakness of the existing visualization method for"time-varying multivariate data with measures",this paper proposed a new visualization method based on Parallel Sets TVBPS,which was composed by a categories layout algorithm ACLEARCR(advanced categories layout based on average heuristic with cardinality reduction),a variate arrangement algorithm based on correlation VABC(variate arrangement based on correlation),and a algorithm called DCPS(depth cue parallel sets).Case studies demonstrate the effectiveness of the method,it shows that the method is conducive to mine the implicit mode in the data sets.


Several factors may lead to school disengagement and dropout. Understanding this process can help schools identify and work with young people at risk of disengaging before this comes entrenched. This thesis reports to the seven stages and results of a research that used vocational school students as co-researchers to investigate the phenomenon of engagement and disengagement at a vocational school. Following the premises that young people have unique perspectives on learning, teaching and schooling, we have built a research design in which all data was collected, analysed and coded by students who were engaged in a 3-stage process of analysis: selecting, contextualising, codifying. First findings of this research show that by analising data, students identified and critically discussed problems, naming ways to change the situation, thus showing the student agency: that when they are asked to participate in their own learning process, change can happen and schools can locally work to reduce dropout. Also, results show why we might include students as co-researchers when analyzing the processes of school disengagement, and dropout.

A gap in the literature on social support among middle-aged and older African Americans and limitations in scales measuring social support among this group indicate a need for a new measure of social support that is sensitive to the cultural context in which this population lives. The literature indicates that social support is a multidimensional, fluid phenomenon, i.e., it has many dimensions and each dimension may have significance for individuals and communities at different periods in time and in different geographical locations. The specific goals of this research were to (1) identify the domains and dimensions of support among middle-aged and older African Americans, ages 38 to 65, that potentially moderate the effects of psychosocial factors on health outcomes; (2) use the research findings to construct a new, contextually valid scale that measures social support among this population in a southern urban community; and (3) document the methodological process by which the first two goals were achieved. The iterative research process consisted of thirty-one methodological steps in nine phases over a four-year period. Six sets of data obtained from a content analysis of popular magazines, five types of interviews, a semi-structured questionnaire, a visual assessment of the community, and participant observation were analyzed for recurrent themes associated with social support. The findings were used to construct scale items that reflect culturally-relevant domains and dimensions of social support that are not typically assessed in traditional scales. Introduction There are a number of excellent scales that measure social support in the general population; however, few, if any, have tapped into the unique experiences of older African Americans. Furthermore, these scales are not comprehensive enough to elicit contextually-based responses from middle-aged and older African Americans, ages 3865, who live in a southern urban community. This may result in investigators missing (or worse yet, misunderstanding) important information regarding social support among men and women in this age category and geographical location. A gap in the literature and limitations in current scales measuring social support indicate a need for a new measure of social support that is sensitive to the cultural context in which middle-aged and older African Americans live. This study had three goals: (1) to identify, using qualitative and quantitative research methods, the domains and dimensions of support among African Americans, ages 38-65, that potentially moderate the effects of psychosocial factors on health outcomes; (2) to use the findings of this research to construct a new contextually valid scale that measures social support among this population in a southern urban community; and (3) to document the methodological process by which the first two goals were achieved. Methodology With NIA (National Institute on Aging) grant funding (5P02AG12058-02), The Duke University Exploratory Center (EC) for Research on Health Promotion in Older Minority Populations was established to conduct multidisciplinary pilot research and interventions and to initiate programs of health education and community outreach aimed at improving the health status of older African Americans. The scientific emphasis was on the interaction of psychosocial, behavioral, and physiological factors as they affect health and illness in older African American males and females. Duke investigators selected hypertension as their research theme. Researchers also were interested in filling a major gap in the scientific literature on health and aging in middle-aged and older African Americans. Duke EC investigators argued that social factors have received little attention in studies of hypertension among this older population. In the proposal stage of the Duke EC grant, the NIA Study Section questioned whether the scales previously used by Duke (including Dressler's Scale of Chronic Role Stressors and the Duke Social Support Index) were "comprehensive enough to indicate the real life levels of support and environmental stress in this population, and were thus leading to an underestimation of the association of the 'environment' with hypertension." In response, the Duke EC decided to conduct a sub-study to develop new scales to measure stress and social support among older African Americans. This research focused on the development of one of the new scales: the African American Social Support


Netflix is an American distribuitor of audiovisual content for home enterteinment. The purpose of this work is to understand how Netflix differs from other players in this
scenario, and how its distinctive features and how it relates to public preference reveal
ruptures in canonical models of accessing audiovisual narratives, and propose new
alternatives for the circulation thereof. We will also analyze the specifics of Netflix as a
producer of original content. We will use as theoretical reference the Cultural Studies,
seeking to launch a multidisciplinary look at our object and seeking to understand
relations of the audiovisual and cultural sphere with relevant elements in other spheres.


IIigh-speed (500 frames * s- ') cinematography of particle capture by Centropages typicus revealed that cells of the dinoflagellate Gymnodinium nelsoni were captured via a rapid extension of the second maxillae after particle detection. The capture sequence requires < 14 ms, and appendage movement (55 Hz) continues during capture. Slow-speed (20 frames. s-l) cinematographic analysis of the feeding behavior of C. typicus showed that the copepod spent at least 95% of its time alternating between periods of rhythmic mouthpart movement and periods of no mouthpart movement. Intervals of activity lasted from 0.1 to 10 s, but the duration of activity was highly dependent on the species and concentration of food available to the copepod. The results suggest considerable plasticity in the temporal partitioning of feeding activity.


Freshwater environments in Asia are being degraded in an accelerating manner by human activities. What is the current state of the freshwater in each watershed?What are the critical factors that cause pollution loads in that region? Sustainable water resource management requires total diagnosis of water environments, covering the state of water and material cycling, evaluation of ecological goods and services, and identification of social and cultural factors that compel people to damage freshwater ecosystems. This study places the watershed as the natural unit of water and material cycling, and aims to set standards for the total diagnosis of environmental health to collect and integrate diverse kinds of environmental information. For this purpose, researchers in the humanities and science (e.g. ecology, geochemistry, engineering, economics, anthropology, sociology) have joined the project and are working co-operatively. This comprehensive research manual helps researchers diagnose the problems in a freshwater environment in cooperation with policy makers and residents who wish to establish a watershedmanagement system.


The goal is to build up an inverse model capable of nding the average grain size history dur- ing an extrusion process and other material constants by using simulated strain and temperature values. This problem of nding the parameter values is based on linear and nonlinear least-squares regressions, cou- pled with microstructure control models and the so- lution of a nite element extrusion model. The prob- lem is ill posed and we use the Tikhonov's regulari- sation to stabilise the solution process. Further some of the parameters in the model are linear and some are nonlinear. We determine the linear parameters using simple linear algebra and for the computation of non-linear parameters we use MATLAB's routine lsqnonlin.


The discovery of nanotechnology and the development of nano structures applied to the investigation of different diseases have opened the possibility to innovate in the field of physiopathology in a way that in the past was inaccessible. Besides this, the inclusion of diagnostic and therapeutic tools allows the possibility to prescribe specific treatments taking genetic resources of patients and monitoring other factors that have an impact in therapeutic response and its prognosis, which results in the application of a personalized medicine.


Software developers often do not build software from scratch but reuse software libraries. In theory, the APIs of a library should be stable, but in practice they do change and thus require changes in software that reuses the library. Our previous study of five reusable components shows that more than 80% of these API changes are caused by refactorings. If these refactorings could be automatically detected, they could be used to automatically upgrade applications. In this paper, we present a technique and its supporting tool, RefacLib, to automatically detect refactorings in libraries. RefacLib uses syntactic analysis in the first phase to quickly detect refactoring candidates across two versions of a library. In the second phase, RefacLib uses various heuristics to refine the results. We used RefacLib to detect refactorings in five open source libraries and frameworks. The experiments show that RefacLib can process realistic code bases and detects refactorings with practical accuracy


Final estimate given by the Index of Adaptability for Q3 2016 has confi rmed the increased level of Russian industry adaptability to the crisis of 2014–2016. The indicator has conclusively registered its all-time maximum at 74% for the entire period of monitoring 1994–2016 (Fig. 1). Review by enterprises of their industrial capaciƟ es esƟ mates was the main factor of growth of the Index of Adaptability.

Background &Aims: Use of balanced fluids as intra-operative fluids substantially decrease the incidence of lactic acidosis; especially after major cancer surgeries. Aim of present study was to compare the effects of two acetate based balanced solutions, PlasmalyteTM and SterofundinTM on lactate, pH, electrolytes and haemodynamics after major onco-surgery. Methods: In this prospective randomised parallel group study, 60 patients undergoing major onco surgeries were randomised in one o fthe two groups to receive either PlasmalyteTM (PL) (30 patients) or SterofundinTM (SF) (30 patients) as an intra-operative fluid. Arterial Blood Gas analysis (ABG) was sampled before surgery (Baseline) and at the time of haemostasis (Post surgery). Heart rate and mean blood pressure were noted every 30 minutes. Blood loss during surgery was replaced with either colloid or blood. Descriptive statistical analyses, including mean and standard deviation for continuous variables, and count and percentage for categorical variables was performed. Student t-test was used to compare continuous variables and Fisher's exact test was used for categorical variables. p <0.05 was considered to indicate statistical significance. Analysis was performed using SPSS Version 23.0 software. Results: The patient's age was found to be comparable in both the groups (p=0.19). There was not any statistically significant difference seen in lactate (p=0.085) or pH (p=0.89) values between the two groups. Electrolyte levels were well maintained within normal limits in both PL and SF groups except calcium which was significantly higher in SF group post surgery(p<0.001). Difference in heart rate and mean blood pressure was found to be insignificant at all time points. Blood loss during the surgery was also similar in both the groups (p=0.937). Conclusion: Both PL and SF balanced crystalloid solutions can be safely recommended as an intraoperative fluid in major oncological surgeries. Both the fluids effectively maintain the pH and significantly decrease the incidence of lactic acidosis during cancer surgeries. Calcium levels are better maintained with the infusion of Sterofundin solution.

The invented coating utilizes the emulsifying technology and solubility resisting technology simultaneously. Through the lipophilicity emulgent and resin the aqueous film forming material, pigment and filler etc. are emulsified into stringy colour colloid, then dispersed in the water solution of protective gum to form into colour pattern coating. Said coating has the same decorating result of oil-in-water type multi-colour pattern coating, but the productive equipment needed is greatly decreased and the productive technological process is much simplified and the productive cost lowers down about 60%.


[eng] The notion of rules is common to the economics of organization and the economics of institutions. These two fields may find a better relation thanks to clearer conceptual distinctions on one hand, and to a more hierarchised systemic approach on the other hand. This may clarify somewhat debates among institutionalist approaches. The paper first discusses the totalizing theory of working rules of Commons, the distinction between the rules of the spontaneous order and those of the organised order in Hayek, and North's view of institutions as rules of the game for organizations. A critical comparison of these three theories raises different questions : the importance of distinguishing organizational and institutional rules, and of taking into account informal and formal rules and their relations at both levels, the teleological character of the organization, the hierarchy of rules at different levels of society. The paper proposes a synthetic and critical approach in trying to articulate individual and collective actions in a systemic framework where organizations are defined as collective and hierarchised ensembles of specific rules, and institutions as general and social rules with higher durability, directly or indirectly sanctioned by the State. The cohesion of various configurations of rules is contingent, subject to permanent tensions, it evolves. It is an essential source of organizational and institutional change in a given system, and it is the origin of crises. [fre] La notion de regle est commune a l'economie des organisation et a l'economie des institutions. Ces deux domaines pourraient trouver une meilleure articulation grâce a certaines distinctions conceptuelles et a une approche systemique hierarchisee, permettant une clarification des debats entre differentes approches institutionnalistes. L'article discute la conception englobante des regles d'activite de Commons, la distinction entre les regles de l'ordre spontane et celles de l'ordre organise chez Hayek, et la conception des institutions comme regles du jeu pour les organisations avancee par North. Une comparaison critique de ces theories souligne en particulier : l'importance d'une distinction entre les regles organisationnelles et institutionnelles, la necessite de prendre en compte les regles formelles et informelles et leurs rapports aux deux niveaux des organisations et des institutions, le caractere teleologique des organisations, la hierarchie des regles a differents niveaux de la societe. Le texte propose une approche synthetique et critique, en cherchant a relier les actions individuelles et collectives dans un cadre systemique ou les organisations sont definies comme des ensembles collectifs et hierarchises de regles specifiques, et les institutions comme des regles sociales generales de plus longue duree, directement ou indirectement sanctionnees par l'Etat. La cohesion des diverses configurations de regles est contingente, sujette a des tensions permanentes, elle evolue. Elle est une source essentielle du changement organisationnel et institutionnel dans un systeme donne et constitute l'origine des crises.


Abstract Single crystals of Ba6Fe45Ti17O106and BaFe11Ti3O23were obtained as major and minor coproducts, respectively, by slow-cooling an off-stoichiometric BaO:Fe2O3:TiO2melt. The former compound exhibits variable stoichiometry, Ba6Fe48−xTi14−xO106, with the Fe:Ti ratio dependent upon the partial pressure of oxygen. The value ofxcorresponds to the equivalents of reduction that occur to maintain electroneutrality as the Ti-content increases. When prepared in air, this phase occurs atx=3 with the stoichiometry Ba6Fe45Ti17O106, while in 100% oxygen thex-value approaches zero with the resulting stoichiometry Ba6Fe48Ti14O106(all Fe3+and Ti4+). The structures of Ba6Fe45Ti17O106and BaFe11Ti3O23were solved using single-crystal X-ray diffraction methods. Ba6Fe45Ti17O106was prepared in polycrystalline form, and further structural details, including accurate Fe/Ti occupancy factors, were determined by a combined refinement using neutron and synchrotron powder diffraction data. (Ba6Fe45Ti17O106: Space groupC2/m(No. 12);a=19.390(1) A,b=20.260(1) A,c=10.076(1) A,β=105.27(1)°;V=3818.5(3)A3;Z=2;ρcalc=5.08 g/cm3. Ba6Fe11Ti3O23= Space groupC2/c (No. 15);a=19.561(1) A,b=8.6614(7) A,c=10.120(1) A,β=105.62(1)°;V=1651.1(3) A3;Z=4;ρcalc=5.08 g/cm3.) Both compounds adopt eight-layer close-packed structures built from alternatingccpandhcp[O, (Ba, O)] layers stacked along thea-direction with a (ch)4repeat sequence. Both structures feature octahedral sites occupied by a mixture of Fe and Ti as well as tetrahedral sites occupied by Fe3+the structural formulas areXIIBa6IVFe6VI(Fe39Ti17)O106andXIIBaIVFe2VI(Fe9Ti3)O23. Both compounds are partially reduced; the former contains 3 moles of Fe2+(or Ti3+) per formula unit, and the latter contains 1mole. The formation of Fe2+is considered more likely than Ti3+, but could not be experimentally confirmed. BaFe11Ti3O23is apparently metastable in air when cooled from above the solidus and could not be prepared as a polycrystalline sample. Indexed experimental X-ray powder diffraction data for Ba6Fe45Ti17O106are given. Polycrystalline samples of this compound were used to measure its magnetic and electrical properties. The magnetic behavior of Ba6Fe45Ti17O106above room temperature up to 1073 K was found to obey the Curie–Weiss law, which indicated a small effective magnetic moment (34μBper mole Ba6Fe45Ti17O106) and a large negative temperature intercept (−806 K). Electrical resistivity measurements between room temperature and 120 K revealed nonmetallic behavior with an activation energy on the order of 0.17eV. At 347 MHz under ambient conditions, Ba6Fe45Ti17O106exhibited a relative permittivity of 24 and a dielectric loss tangent of 0.10.


Abstract Modified Thevetia peruviana shell activated carbon for sorption of dimethoate from aqueous solution derived with potassium hydroxide (KOH) was studied at different concentrations for its potential application in water treatment. The batch sorption was investigated using dimethoate solution of 10–100 mg/L concentrations. Proximate analysis was determined and changes on the surfaces and structure of the TPS were characterized after chemical activation with KOH using XRD, FTIR, SEM–EDAX, pHpzc, BET. The quantum chemical calculation for dimethoate yielded molecule associated energies of –9.8421 (HOMO) and –2.3879 (LUMO) and a total energy of –53,376.2. The kinetic of the sorption was modeled which indicated the sorption equilibrium time as 90 min and pseudo-first order kinetics model showing R2 = 0.994 provided a better description of the process. Analysis of sorption equilibrium revealed that the data fitted well to Freundlich sorption isotherm model (R2 = 0.966), indicating multi-layer sorption of dimethoate on the surface of sorbent. The sorption of dimethoate onto KOHTPS shows 92.60% removal efficiency.


A patient with a history of severe osteoarthritis and restless legs syndrome (RLS), who had recently undergone orthopedic surgery, began to experience the involuntary movement and pain associated with RLS. These symptoms, which also deprived the patient of sleep, complicated her postsurgical rehabilitation. The onset of symptoms coincided with attempts to discontinue her opiate analgesic regimen. The patient was evaluated; no significant comorbid conditions or drug therapies that might have aggravated her RLS symptoms were noted. After a discussion of the risks and benefits of the pharmacologic options, it was decided that Tramadol was the best therapy for this patient. A follow-up review of the patient's clinical course at 7, 30, and 60 days showed that Tramadol was quite effective in controlling her RLS symptoms and joint pain.
