Introduction BODE index is used commonly in patients with COPD to predict mortality and relies on the body mass index (BMI). Muscle mass has been shown to be better predictor of mortality than BMI in COPD.1 In the DECAF model,2 low serum creatinine was not evaluated as a marker for increased mortality for patients with COPD. Serum creatinine levels are routinely checked during acute admissions and as the levels are partly dependent on muscle mass, it may be possible that it can be used as a predictor for increased mortality in these patients. Objective The aim of this study is to determine whether there is any significant association between low serum creatinine and mortality in patients with severe COPD. Methods Retrospective analysis of serum creatinine values at admission and within the last 1 year prior to admission with mortality at 30 days and 1 year after admission in patients admitted with acute type 2 respiratory failure due to COPD over period of one year to a respiratory ward (N=130). The statistics were calculated using Chi-squared test. Results The results are shown in table 1. The results suggest significant relationship between the 1 year pre-admission creatinine values and mortality at 1 year (p=0.0003). At 30 days, there does not appear to be a significant relationship between low creatinine and mortality. Conclusions The relationship with mortality appears to be stronger with pre-admission creatinine values rather than the admission values and appear to show highest risk of mortality at 1 year after admission.

This article looks at the predominance of freelancing in the film and television industries as a lens to examine the persistence of gender inequalities within these fields. Previous research has indicated that women fare better in larger organizations with more stable patterns of employment, and in this article we explore why that might be the case, by focusing on the experiences of female freelancers at a moment when project-based, precarious work and informal recruitment practices are increasing in the UK film and television sector. We highlight in particular the ways in which gender inequality is mediated by age and parental status, and the impact of intersectional identities on women's ability to sustain a career in film and television.


This article focuses on the subject of iron ore. Though analyzing the relationship between iron ore consumption and economic development about China and American, it is found that the per capita consumption of iron ore in China was too early, which is not conducive to economic development. Through elaborating the relationship between the consumption and the industrial structure of iron ore, it is revealed that China's industrial structure changes with iron ore consumption intensity and China's economic growth is realized at an excessively high cost of resources.


Under the new situation and tasks we should bring forth new ideas and make improvement in the substance,form,method and means of the ideological and political work on the basis of carrying on its fine tradition.Here we discuss the effective combination of the ideological and political work of employees with modern management according to the characteristics of basic units of agricultural research institutions.


The fixed-polarizer ellipsometer measures thickness of thin films. It is simple, inexpensive, and provides a linear response over a range of 800 A. We develop a matrix formulation to describe the optical characteristics of the instrument and apply it to the case of a single thin film on a substrate. Excellent agreement is found between experimental and simulated results. Applying the instrument to optical immunoassay, we show that its sensitivity can extend to 4 pg/ml, depending upon the analyte. This compares favorably with commercially available manual and automated immunoassay systems. The fixed-polarizer ellipsometer appears to be well-suited for use in laboratory and production environ- ments. © 1999 Society of Photo-Optical Instrumentation Engineers. (S0091-3286(99)02205-9)


Civic engagement is important for the positive development of adolescents. As such, many youth development programs promote civic engagement, particularly community service and volunteerism. This report is a program evaluation of a youth leadership seminar that seeks to empower adolescents to engage in community service. Using a pre to post mixed-methods design, we evaluated 114 adolescent participants on several psychosocial outcomes. Findings indicated that participants experienced positive change that was consistent with program goals. Quantitative findings demonstrated self-reported increases in areas of cognitive autonomy, moral ideal and social responsibility. Qualitative findings included the important themes of an increased desire to volunteer, confidence, and positive feelings towards self. Implications of these findings and future directions are also discussed.


Objective: To analyze the results of application of the two surgical techniques in the treatment of the consequences of urethral injuries (CUI). Methods: 38 patients aged 16.4±1.9 years with CUI were examined. CUI were localized in the area of the scaphoid fossa (n=3), the penile part (n=9), the bulbous region (n=6). Multi-site and panurethral lesions were noted in 8 and 12 cases, respectively. Additional research methods included ultrasound examination of the bladder, uroflowmetry, residual urine measurement, and, if necessary, retrograde and voiding urethrography. The patients underwent two types of surgical intervention: one-stage (16 patients, 1st group) and two-stage (22 patients, 2nd group) urethroplasty using a buccal mucosal flap. The results of surgery were assessed by ascending urethrography and uroflowmetry. The follow-up period ranged from 6 to 24 months. Results: The immediate and long-term results between the two groups showed significant difference. According to uroflowmetry data, the main indicator of the effectiveness of surgical intervention was a stable retention of maximum urine flow rate at least 15 ml/sec. In the 1st group, there was one case of early wound dehiscence with the formation of a fistula. In the 2nd group, early divergence was observed in 8 cases, it was also accompanied by formation of fistulas. These complications required additional surgical intervention; their correction was deferred. Conclusion: One-stage urethroplasty using a buccal mucosal flap for CUI proved to be safer and more effective compared to the two-stage technique Keywords: Consequences of urethral injury, urethrography, uroflowmetry, buccal flap.


The quest for combining superconductivity and the quantum Hall effect is several decades old. The conceptual idea is simple and powerful: a chiral edge mode is a one-way street. Therefore, when an electron reflects from an edge state into a superconductor, the resulting particle—no matter whether electron or hole—propagates in the same direction as the incoming electron. This way, the spatial separation between electrons and holes is maximal and the local reflection is fully prohibited. If the probability for the hole to exit the superconductor is larger, a positive voltage between the injecting electrode and the superconductor results in a negative current between the superconductor and the collecting electrode, providing a straightforward signature of nonlocal Andreev reflection. A related phenomenon, quantum Hall supercurrent, appears when two superconducting electrodes are connected by a quantum Hall edge. Its hallmark is the periodicity of the supercurrent with the number of normal (h/e) and not superconducting (h/2e) flux quanta of magnetic field through the junction area. The change in periodicity compared to the regular Fraunhofer pattern in Josephson junctions also arises due to the chiral nature of the edge mode: all quasiparticles carrying supercurrent must encircle the complete sample. Just like Andreev reflection, quantum Hall supercurrent is a nonlocal phenomenon that requires coherent transport of quasiparticles in contact with a superconducting electrode. Both are therefore suppressed by superconducting vortices that act like quasiparticle sinks and by dephasing due to inelastic scattering.


The observed solar activity is believed to be driven by the dissipation of nonpotential magnetic energy injected into the corona by dynamic processes in the photosphere. The enormous range of scales involved in the interaction makes it difficult to track down the photospheric origin of each coronal dissipation event, especially in the presence of complex magnetic topologies. In this paper, we propose an ensemble-based approach for testing the photosphere–corona coupling in a quiet solar region as represented by intermittent activity in Solar and Heliospheric Observatory Michelson Doppler Imager and Solar TErrestrial RElations Observatory Extreme Ultraviolet Imager image sets. For properly adjusted detection thresholds corresponding to the same degree of intermittency in the photosphere and corona, the dynamics of the two solar regions is described by the same occurrence probability distributions of energy release events but significantly different geometric properties. We derive a set of scaling relations reconciling the two groups of results and enabling statistical description of coronal dynamics based on photospheric observations. Our analysis suggests that multiscale intermittent dissipation in the corona at spatial scales >3 Mm is controlled by turbulent photospheric convection. Complex topology of the photospheric network makes this coupling essentially nonlocal and non-deterministic. Our results are in an agreement with the Parker's coupling scenario in which random photospheric shuffling generates marginally stable magnetic discontinuities at the coronal level, but they are also consistent with an impulsive wave heating involving multiscale Alfvénic wave packets and/or magnetohydrodynamic turbulent cascade. A back-reaction on the photosphere due to coronal magnetic reconfiguration can be a contributing factor.

Abstract In 1888, Edvard Holm brought out his still much-cited book, Kampen om Landboreformeme i Danmark.1 By his title, the "conflict over the agrarian reforms", Holm meant the clash of opinion which preceded and contributed to the reforms initiated under Crown Prince Frederik's de facto regency, beginning in 1784. But the debate begun by Danish landowners, officials, and opinion-makers did not end with the reform era itself. It was continued by Danish historians, who have pursued it with remarkable intensity and no small passion down to the present day.


Since the new crown epidemic, mask‐wearing has become a new normal in people's work and life. The inspection mechanism for mask‐wearing at the entrance and exit of public places is seriously insufficient. The phenomenon of "pick‐up on entry" has led to the severe formalization of mask‐wearing inspection. Manual detection of mask‐wearing in an open and dynamic crowded environment is unrealistic, which is not only time‐consuming and labor‐intensive but also cannot achieve early warning throughout the entire process. In response to this problem, this paper proposes a real‐time recognition and early warning method for mask‐wearing in an open, dynamic, complex environment based on improved YOLOv5 R6.1. First, replacing the first Conv structure of the backbone network in the YOLOv5 R6.1 model with an improved Stem structure to minimize the computational overhead while improving the performance. Then by normalizing the data, the random erasure data expansion technique is used to enhance the antiocclusion robustness of the algorithm. Finally, according to the mask‐wearing specification in the training data set, optimizing and adjusting the anchor box parameters of the YOLOv5 R6.1 model to improve the model's ability to recognize small targets. The experiments are based on open data sets, and the results show that the mean precision (mAP), precision, and recall of this method reach 92.9%, 94.1%, and 88.5% on average, and the average frames per second (FPS) reaches 117. Moreover, the mAP and FPS are improved by an average of 6.5% and 474% compared with algorithms based on RetinaNet, Attention‐Retina, Single Shot multibox Detector, Fast‐RCNN, YOLOv4, and YOLOv5.

We sequenced the genome of Streptomyces sp. JB150, isolated from a unique site of the Thar desert in India. Genome mining of the JB150 genome revealed the presence of many interesting secondary metabolic biosynthetic gene clusters (BGCs). The encoded parvome of JB150 includes non-ribosomal peptides, polyketides including β-lactone, butyrolactone, ectoine, lantipeptides, lasso peptides, melanin, resorcinol, siderophores, terpenoids, thiopeptides, and other types of hybrid compounds. Among them, ~30% BGCs displayed a high degree of novelty. The genome of JB150 was enriched for a large assortment of specialized genes coding for the production of many interesting biomolecules comprising compatible solutes, multiple stress-response regulators, transport proteins, protein secretion systems, signaling molecules, chaperones and storage reserves, etc. The presence of diverse members of CAZymes enzyme families, high numbers of riboflavin, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), trehalose and aromatic compounds synthesis genes, putative orthologues to several of the classical fatty acid synthesis components, prototrophy for many essential amino acids exhibit metabolic versatility of JB150 to inhabit in the extreme desert environment. Besides, the genome of JB150 was observed to specifically encode thiazole-oxazole-modified thiazolemicrocin (TOMM) and ectoine. The comparison of the complete genomes of Streptomyces sp. JB150 and seven other actinomycete strains belonging to different desert ecosystems unveiled the presence of many previously undetected, distinctive, biological, and genomic signatures. We propose that these genetic traits endowed by these strains are essential for their adaptation in the highly underprivileged, extreme ecosystem of the Thar desert to cope with multiple abiotic stressors, oligotrophic nutrient conditions and to produce a huge repertoire of diverse secondary metabolites.


SummaryRates of CO2 production by cv Idared apples were progressively reduced by lowering O2 levels from 21% to 2% and 1%. Although lowering the temperature from 4° to 2°C also reduced the respiration rate, fruits stored in 1% and 2% O2 were respiring faster after 100 days at 0°C than at 2° or 4°C. After 192 days the air-stored fruit also showed an increase in respiration rate at 0°C. These higher respiration rates preceded the development of low temperature breakdown in fruit stored in air, 2% and 1% O2 at 0°C and in 1% 02 at 2°C. Progressively lower O2 concentrations reduced ethylene production whilst increasing the retention of acid (expressed as malic), soluble solids, chlorophyll and firmness. In the absence of low temperature breakdown the effects of reduced temperature on fruit ripening were similar to those of lowered O2 concentrations. The quality of apples stored at 4°C in 1% O2 was markedly better than in 2%; the fruits were also free of core flush (brown core) and other physiological disorders.

Korean folk medicine ``BoRiSuNaMu`` has been used mainly to cure apepsia and cough. With regard to the botanical origin of BoRiSuNaMu, it has been considered to be Elaeagnus species of Elaeagnaceae, but there was no pharmacognostical conformation on it. To clarify the botanical origin of ``BoRiSuNaMu``, the anatomical characteristics of the branches of Elaeagnus species growing wild in Korea, Elaeagnus glabra, E. macrophylla, E. multiflora, E. submacrophylla, E. umbellata and E. umbellata var. coreana were studied. As a result, it was clarified that ``BoRiSuNaMu`` was the branches of Elaeagnus umbellata.


Progeny from two genetically differentiated strains of the fall armyworm, Spodoptera frugiperda (J. E. Smith), were monitored for growth and development on constituent altered artificial diets. The effect of altered diets on larval growth and pupal weight was contingent on fall armyworm strain (rice or corn). Modified pinto bean diets deficient in vitamin supplements reduced pupal weights of individuals of the rice strain. Larval growth rates were reduced when fall armyworms were reared on a modified pinto bean diet or pinto bean diet augmented with sucrose. However, growth rates were significantly increased when larvae of the rice strain were fed a velvetbean caterpillar diet without sucrose. Strain development on a modified pinto bean diet containing torula yeast had growth rates of 90 mg/d compared with 40 mg/d on a modified pinto bean diet with brewer's yeast. A velvetbean caterpillar diet devoid of yeast significantly increased corn strain growth rates; however, the same diet decreased development of the rice strain. Larval maturation on the modified pinto bean diet was significantly reduced compared with growth on a modified pinto bean diet without soy protein or when 70% soy protein was substituted for 90% soy protein. The addition of salt to the standard rearing diets dramatically increased larval growth rates.


The boson Hubbard model has been extensively studied as a model of the zero temperature superfluid/insulator transition in Helium-4 on periodic substrates. It can also serve as a model for vortex lines in superconductors with a magnetic field parallel to a periodic array of columnar pins, due to a formal analogy between the vortex lines and the statistical mechanics of quantum bosons. When the magnetic field has a component perpendicular to the pins, this analogy yields a non-Hermitian boson Hubbard model. At integer filling, we find that for small transverse fields, the insulating phase is preserved, and the transverse field is exponentially screened away from the boundaries of the superconductor. At larger transverse fields, a ``superfluid'' phase of tilted, entangled vortices appears. The universality class of the transition is found to be that of vortex lines entering the Meissner phase at H_{c1}, with the additional feature that the direction of the tilted vortices at the transition bears a non-trivial relationship to the direction of the applied magnetic field. The properties of the Mott Insulator and flux liquid phases with tilt are also discussed.


To study the effect of Bradyrhizobia (Bradyrhizobium japonicum ) and phosphate solubilizing bacteria (Pseudomonas spp.) application on soybean in rotational system (soybean-rice-rice), the experiments were carried out at three different provinces of Mekong delta viz., An Giang, Can Tho and Dong Thap. The treatments composed of different combination level of inorganic nitrogen fertilizer levels (namely 20, 40, 60 kg N/ha) and biofertilizer (Bradyrhizobium japonicum + Pseudomonas spp.) as compared to conventional farmers' fertilizer level (80 N - 60 P2O5 - 30 K2O kg/ha). The results showed that application of Bradyrhizobia (Bradyrhizobium japonicum ) and phosphate solubilizing bacteria (Pseudomonas spp.) can enhance the number of nodules, dry weight of nodules, yield components, grain yield, soil nutrient availability and uptake of soybean crop. Moreover, the economic efficiency could be increased in term of reducing the production cost for soybean from 785,000 to 1,000,000 VND/ha.


The traditional modelling and simulation analysis methods based on graph theory are difficult to present the structural characteristics and dynamic laws of cyber-physical power systems (CPPS). In order to reduce the complexity of the attack graph, this paper proposes a CPPS robustness analysis method based on the reachable matrix. Based on the evolution of the augmented adjacency matrix of cyber-physical power system, this method uses the reachable matrix to obtain the maximum connectivity matrix of the system (the adjacency matrix corresponding to the largest connected subgraphof cyber-physical power system), and then, evaluates andanalyses the robustness of cyberphysical power system. The IEEE118 node standard model is taken as an example to carry out the simulation experiment. The experimental results show that the reachable matrix has feasibility in the robustness analysis of cyber-physical power systems. Further through the contrast experiment found that compared with the robustness analysis method based on graph theory, the proposed method in this paper can reduce the modelling complexity of the mutual coupling network, reduce the complexity of the attack graph, and clearly and intuitively show the structural characteristics and dynamic laws of the network connection in the system.

Nest predation is one of the main drivers for the failure of avian breeding,and is therefore an important factor affecting avian breeding success rate.Consequently,it is an important research topic in avian breeding ecology.Identifying the main nest predators and factors affecting nest predation is critical for understanding the breeding success population growth,and population size of particular bird species.Nest predation rates are generally affected by the behavior of predators,the degree of habitat fragmentation,characteristics of nest,and the life history of the bird.The main nest predators of birds are mammals,raptors,crows,snakes and insects,with different predators present in different habitats.A4-year period of field study was carried out from 2009 to 2012 during the breeding season of late April to early August to investigate the nest predation rate of four artificial nest-box breeding passerines(Varied Tit Parus varius,Marsh Tit P.Palustris,Great Tit P.major and Browed Flycatcher Ficedula zanthopygia) and its influencing factors in Xianrendong National Nature Reserve,Liaoning Province.Six video cameras were randomly installed on the boxes that were used by the birds to record the nest predators after the nestlings were five days old.Each nest was monitored for three times,once every three days,from 8:00 am—12:00 noon.A total of 40 nests were monitored for a period of 480 hours.Of the 238 nests(74Varied Tit nests,21 Marsh Tit nests,118 Great tits nests and 25 Browed Flycatcher nests) recorded,35(14.7%) nests were predated,and 91.4%of which were predated during the nestling stage.There was no significant difference in the predation rates among the four species(x~2= 0.429,df=3,P= 0.934).According to our observation(Nest predators that we saw or recorded by the cameras),seven nest predators were detected,and of which four were Korean rat-snake(Elaphe anmnal) and three were Dione rat-snake(Elaphe dione).Thus it indicated that Elaphe snakes were the dominant nest predators,accounting for 94.3%of the nest predation of these four small nest-hole birds.We measured 18 habitats and counted four nests parameters of the 35 predated nests and 42 control nests,which were chosen at random near the predated nests.Binary logistic analysis incorporating the combined effect of the 22 different variables revealed that the main factors affecting nest predation were slope,the extent of bare ground and herb coverage,all of which had significant effects on nest predation.Other factors such as hatching time,slope position and distance to nearby roads,also affected nest predation,with their effects were marginally significant.There was no effect of nest height,tree thickness,nest-box age,clutch size and distance on nest predation.In all,nests in the steeper slope position,higher herb coverage,lower coverage of bare ground,and those that were closer to stones or hatched a later time were more vulnerable to nest predation.In addition,we also found that artificial boxes with smaller exits could prevent predation by rodents.


The UK is going through its worst nurse shortage crisis for some time. With nurse recruiters too preoccupied with attracting overseas nurses, there has been too little emphasis and focus on the need for developing home-grown talent. Autumn is traditionally the time of year when there are large intakes of nursing students on preregistration programmes. We should be doing whatever possible to make our profession welcoming and attractive to new learners. Unfortunately, there is often too much negativity and lack of respect for students when they enter clinical placements.

A 43-year-old man presented with persistent pain on the medial side of his left knee, 1 year after a bone-patellar tendon-bone autograft ACL reconstruction. Besides a dysfunctional ACL, earlier arthroscopy had already revealed a focal full-thickness chondral lesion (25 × 12 mm) of the medial femoral condyle (Figure 1A) and mild degenerative changes in the lateral compartment of the knee. The patient was offered a mosaicplasty of the medial femoral condyle. After a medial arthrotomy of the knee, 3 cylindrical osteochondral plugs (8 mm diameter) were harvested from the lateral throchlea (donor site) and transplanted to the chondral defect in the medial femoral defect (recipient site), using the mosaicplasty technique (Hangody et al. 1998, Bobic 1999, Hangody and Fules 2003, Horas et al. 2003). The donor site defects were each fi lled with a press-fi tted cylindrical osteo-periosteal plug obtained from the proximal tibia. It was hypothesized that these plugs would enhance healing of the subchondral bone and that the covering periosteum would enhance resurfacing of the donor site defects with fi brocartilagenous tissue. Initially, the patient's symptoms clearly improved and a postoperative MRI showed restoration of the joint surface at the original chondral lesion in the medial condyle 3 months after surgery (Figure 1B). The 3 transplanted osteochondral plugs were still clearly visible in the subchondral bone, with signs of osseous integration. One plug appeared to have been placed rather too deeply, as seen from the step-off in the subchondral bone (Figure 1B, 2A). At the lateral aspect of the trochlea, the 3 donor site defects were also still clearly visible (Figure 1C). The osteo-periosteal plugs from the proximal tibia appeared to have remained in situ and some resurfacing of the defects had occurred. After 3 years the knee became symptomatic again, with pain and swelling. Radiographic evaluation revealed mild degenerative changes (Figure 1D). Conservative treatment was not accepted and a total knee arthroplasty was performed. This procedure eventually provided good-quality retrieval specimens for histological evaluation of a mosaicplasty.

We found that Ca additive effectively suppresses the photo-darkening (PD) effect in Yb-doped silica fiber even at 6.0 wt% of high Yb2O3 concentration. Ca ion works as a stabilizer to maintain the Yb3+ valence state. We hypothesize that this phenomenon may reflect the local charge balance effect in silica glass. This Yb-Ca co-doped silica fiber can be useful for high-power fiber lasers.


Review and analysis of road pavement testing means and methods are presented. Complexity of thes e methods is pointed out. New approach to pavement te sting using vibro-excitation and logarithmic decrement an alysis of extinguishing free oscillations is proposed and its advantages are shown. There are two main groups of methods to find the ac tual strength characteristics of the pavement: destructi ve and non-destructive. The latter are divided into static and dynamic types of methods. Nevertheless, some disadvantages exist in applicati on of those methods, and a new application of vibration t esting method is proposed.


The ADP-ribosylation factor-like (Arl) family of small G proteins are involved in the regulation of diverse cellular processes. Arl2 does not appear to be membrane localized and has been implicated as a regulator of microtubule dynamics. The downstream effector for Arl2, Binder of Arl 2 (BART) has no known function but, together with Arl2, can enter mitochondria and bind the adenine nucleotide transporter. We have solved the solution structure of BART and show that it forms a novel fold composed of six α-helices that form three interlocking "L" shapes. Analysis of the backbone dynamics reveals that the protein is highly anisotropic and that the loops between the central helices are dynamic. The regions involved in the binding of Arl2 were mapped onto the surface of BART and are found to localize to these loop regions. BART has faces of differing charge and structural elements, which may explain how it can interact with other proteins.


In Scripture, name-giving not only occurs quite frequently, it also carries narrative weight. Therefore, it is hardly surprising that a great amount of academic literature has been dedicated to the historical, linguistic, formal and literary aspects of the derivation of names. Unfortunately, discussions concerning name-giving have concentrated for decades on the existence and the importance of aetiologies, thereby relegating methodological questions concerning the 'name-giving' form to the periphery for a long time.1 The answer to these questions, however, touches primarily upon the difference between the interpretation of names in the Bible and those in Targum and Midrash. Name-giving in biblical literature can be divided into two variants according to J. Fichtner, who many years ago analysed this form with regard to the historical books.2 The first variant concerns the namegiving of persons. Here, two different elements, the name-giving itself ('and he called his/her name such and such') and the etymological aetiology which follows ('for he said ...' plus aetiological motive), are causally bound together, as can be seen in the example of the namegiving of Gershom (Ex 2:22): Sippora gave birth to a son and Moses


Optimization models have been widely applied in statistics. This paper concentrates the interval form of valued linear programming model (IVLPM). The range of the data and confidence interval of the data are considered as interval. An IVLPM is a linear programming model (LPM) with interval form of the coefficients in the objective function and all requirements. The solution of the IVLPM is analysed numerically.


EARLY IN 1970 THE GOVERNMENT OF SURINAM (FORMERLY, DUTCH GUIANA) RETAINED A MULTIDISCIPLINARY TEAM TO ORGANIZE A COMPREHENSIVE PLANNING STUDY FOR THE AREA OF ITS CAPITAL, PARAMARIBO. AN UNUSUAL FEATURE OF THE TEAM'S WORK WAS THAT TRANSPORTATION PLANNING WAS INTEGRATED FROM THE BEGINNING WITH LAND USE PLANNING. THE APPROACH EMPLOYED IN THIS EFFORT, FROM GENERAL ORIENTATION THROUGH FINAL REPORT, IS DEPICTED IN A SYSTEM FLOW CHART IN WHICH TRANSPORTATION AND TRAFFIC DETERMINED THE CRITICAL PATH. TRADEOFF ANALYSES WERE CONDUCTED BY UTILIZING A SERIES OF "FACET PLANS" IN WHICH A MAJOR FACET OF THE PLAN (E.G., TRANSPORTATION, UTILITIES, PUBLIC SERVICES) WAS USED AS THE PLANNING CRITERION, THEN OBSERVING ASSOCIATED BENEFITS AND COSTS AS A MEANS OF APPROXIMATING AN OPTIMUM MIX FOR THE SYSTEM AS A WHOLE AND FOR EACH FACET PLAN. THE FORMER PRODUCT---THE OPTIMUM MIX---WAS DELINEATED IN SHORT-TERM AND LONG- TERM (MASTER) PLANS. THE PLANNING PROCESS WAS DESIGNED SO AS TO BE ITERATIVE, I.E., CONTINUOUS.


The term computer anti-forensics CAF generally refers to a set of tactical and technical measures intended to circumvent the efforts and objectives of the field of computer and network forensics CF. Many scientific techniques, procedures, and technological tools have evolved and effectively applied in the field of CF to assist scientists and investigators in acquiring and analyzing digital evidence for the purpose of solving cases that involve the use or misuse of computer systems. CAF has emerged as a CF counterpart that plants obstacles throughout the path of computer investigations. The purpose of this paper is to highlight the challenges introduced by anti-forensics, explore various CAF mechanisms, tools, and techniques, provide a coherent classification for them, and discuss their effectiveness. Moreover, the authors discuss the challenges in implementing effective countermeasures against these techniques. A set of recommendations are presented with future research opportunities.


With the increasing interconnection of distributed energy resources, traditional energy consumers are becoming prosumers, who can both consume and generate energy. As grid parity for photovoltaic generation has been reached in most countries, prosumers increase their self-consumption levels by operating battery electricity storages (BES). Most BES are currently managed by a rule-based control system. In this paper, we compare such a rule-based control system with alternative control algorithms. The alternative approach uses standard machine learning tools to predict household load and optimize BES usage. Even if individual household load prediction is associated with a high level of uncertainty, the forecast generated can be used by a smart BES management system to increase the revenues of prosumers. Revenues can be increased by an average of 12 %.


The objective of this present research is to formulate floating sustained release matrix tablets using hydroxyl propyl methyl cellulose (HPMC) K15M as matrix forming polymer and sodium bicarbonate as a gas generator. Meloxicam was used as model drug. The directly compressed tablets were evaluated for physical parameters such as weight uniformity, hardness, friability, drug content, in-vitro buoyancy, and swelling index. It was observed that the buoyancy lasted for up to 24 h and supported by invitro dissolution studies. The dissolution data was subjected to various release kinetic models.

Self-powered materials prepared by combining functional assemblies with energy harvesting films have attracted increasing research attention recently and are applied in many fields, such as in drug delivery and therapeutic devices, tissue engineering materials, surface-enhanced Raman spectroscopy substrates, hybridized photocatalysts, mechanoluminescent materials, and optoelectronic devices, amongst others. Compared with self-powered devices containing a management circuit, self-powered devices obtained by directly interfacing the energy generation unit and the electricity consumption unit have higher efficiencies and exhibit low power loss. More compact designs can also be developed, which results in devices with smaller volumes, further facilitating their usage. In this review, we document and discuss self-powered devices built by interfacing the electricity generation units and the electricity consumption units without being connected by an electric circuit. The electricity generating units and enhanced functionality as well as function promoting mechanisms are discussed. We expect that this review will help promote the development of integrated self-powered devices and lead to advanced systematic materials that better address current medical, environmental, and energy challenges.

Lack of awareness and mismanagement on solid waste are the main causes of present human health damage and ecosystem quality deterioration. This study was designed to assess the level of awareness and knowledge of local residents concerning solid waste management in Al-Nassyriah City of Iraq. Primary data were collected from local residents through questionnaire and interview. A total of 1,794 questionnaires were completed by the respondents that were randomly selected from 12 suburban areas located in Al-Nassyriah City. A descriptive cross-sectional analysis was performed among local communities and results were analyzed by using SPSS software. Results from the survey showed that 67% of respondents were dissatisfied with the current practice of solid waste management in their city. The results also showed that low-level of knowledge on relevant laws and regulations pertaining to solid waste was observed among respondents. Although half of the respondents were aware about the importance of managing solid waste, however, most of them failed to put their knowledge and awareness into practice. Therefore, extensive and continuous efforts by various stakeholders are urgently needed to enhance public awareness towards sustainable solid waste management in developing countries, particularly in Al-Nassyriah City, Iraq.


Dragon and White Tiger crude oils are two different kinds of paraffin crude oils of Vietnam. The screening studies on their fluidity changes under the influence of magnetic forces have been completed. The relationships between their viscosity changes and magnetic force strength, temperature, and duration of treatment were obtained, the optimal conditions for the viscosity reducing were found. The changes in paraffin crystallization under magnetic fields were studied using scanning electronic microscopy (SEM). The possibilities to defense and remove wax clogging and deposition obtained by magnetic treatment was also studied and proved. Base on these data, the mechanism of the influence of magnetic fields on paraffin deposition control was proposed. The data can also serve as a basic in designing and construction high effective magnetic tools to improve liquidity of high waxy crude oils in this area. Introduction Paraffin or wax deposition has been recognized as a major problem from the inception of oil industry all over world. It can occur and present a lot problems in oil production, transportation and storage. These cause the reduced crude oil pumping rate, severe start up problems after pipeline shut down and wax deposition. Paraffin deposits on the wall of down hole turbulars and other places like near entrances and exit of chokes, collars of similar restrictions in the flow path. Among existing two physical and chemical groups of methods to control this problem, wax crystal modifiers maybe the best in able to resolve, partly, these low temperature troubles by modifying the rheological properties of waxy crudes and decreasing wax deposition, resulting in a better pump ability and restability. Despite these advantages, the chemicals are expensive, environmentally hazardous, they also are very sensitive, they can work effectively only on specific crudes. There was one more method, the magnetic technology, which was based in an applied magnetic fields, can very successfully remove or inhibit crude oil gathering deposits, both organic and inorganic without affecting the crude characteristics. Despite the magnetic technology has been cited in the literature and studied since nineteenth century, while naturally occurring magnetic mineral formations were used to decrease the formation of scale in cooking and laundry applications, and now a day, a thousand of magnetic fluid conditioners (MFC) have been installed in oil wells in many places in the world , the mechanisms of its effects on deposition control, especially on crude oil wax deposition was not so far clearly studied and proved. The purpose of this study is to confirm that magnetic fields effect on liquidity of crude oils via fluid viscosity and paraffin crystallization process, and try to find out the mechanisms of these effects. Review of the mechanisms of deposition control effects of magnetic fields According to many authors, deposits controlled by magnetic treatment can be divided into two groups: 1. Inorganic: The general working principle of magnetic treatment is a result of the physical interaction. When orthogonal fluid of ions pass through magnetic field, the Lorenz force is exerted on each ions. These forces orientates the interaction between magnetic fields and moving electric charges in the form of ions and are the governing mechanisms to explain the inhibition effects of magnetic fields on scale formation. Under the influence of magnetic fields, the forces of opposite charge ions are in opposite directions. The redirection of the particles tends to increase the frequency with which ions of opposite charge collide and combine to form a mineral precipitate, or insoluble compound. When this reaction takes place within a heat exchanger, the mineral form of the most common scale is called calcite. Calcite is adherent mineral and makes build-up of scale on the surface. At low temperature, the mineral form SPE 68749 Studying the Mechanism of Magnetic Field Influence on Paraffin Crude Oil Viscosity and Wax Deposition Reductions Nguyen Phuong Tung, SPE, and Nguyen Van Vuong, and Bui Quang Khanh Long, and Ngo Quang Vinh, and Pham Viet Hung, Institute of Materials Science-Vietnam NCNS, and Vu Tam Hue, Petro Vietnam, and Le Dinh Hoe, Vietsov Petro 2 N.P. TUNG, N.V. VUONG, B.Q.K. LONG, N.Q. VINH, P.V.HUNG, V.T. HUE, L.D. HOE SPE 68749 is usually aragonite, which is much less adherent to surrounding surface, and tends to form smaller-grained or softer-scale deposits. It has been reported that under magnetic treatment the different aragonite to calcite ratio was obtained and resulted in reducing scale formation. 2. Organic deposits: Paraffin molecules are constituents of crude oils, which are soluble under reservoir conditions. As the equilibrium of the oil is upset by the pressure and temperature changes at the well bore the paraffin will come out of solution as a heavier than oil precipitate. The pressure effects on the ability of the oil to dissolve paraffin are not great but the volatilization of light hydrocarbons, like methane, ethane, propane, butane, etc. substantially decreases the solubility of the paraffin in the oil. Obviously the major factor in the precipitation of paraffin from crude oil is the temperature falling to a sub cloud point level. The cloud point is defined as the temperature at which paraffin crystals first precipitate from solution at atmospheric pressure. Paraffin will come out solution on a cold surface even if the bulk oil temperature is well about the cloud point temperature. The kind and amount of depositions of heavy organic from petroleum fluids vary depending on the hydrocarbons present in oil and the relative amounts of each family of heavy organic. There are three recognized mechanisms for deposition of paraffin in oil field systems. They are molecular diffusion, shear dispersion and Brownian motion. The molecular diffusion is the deposition mechanism prevalent for tubing deposition in flowing wells that maintain oil temperature well above the cloud point until the oil is coming up the tubing. As the hot oil encounters the tubing wall at the cloud point temperature paraffin crystals come out of solution and adhere to the wall. They are held by adsorption forces depend on the free surface energy of paraffin and the steel pipe . Shear dispersion of the precipitated wax crystals takes a place after the oil has fallen lower cloned point temperatures and the crystals are transported to the wall by the shearing of the oil at the surface of the tubing or flowline. Crystals will deposit on layers formed by molecular diffusion. Precipitation of all lower molecular weights of wax may not be complete by the time of oil enters the flowline in some cases. As the temperature drops in the flowline, the lower molecular weight paraffins can establish the base layer of paraffin for the crystals out of solution on which to adhere. Thus molecular diffusion can play an important part throughout the entire system. It depends on the solvency of the oil to its paraffin. Shear dispersion is the main mechanism of deposition for any situation where oil temperatures are sub cloud points. Here, deposits form from wax crystals out of solution. Any inorganic particles, water, asphaltenic materials, or even another wax crystal can act as a nucleation site. The impurities in the shear dispersion deposits actually make the deposit easier to treat. The entrapped water and oil provide an entrance for the surfactant dispersing additives to penetrate the deposit and carry in additional fluid to coat the paraffin crystal to crystal bonds are broken by the dispersing. Brownian motion is considered almost nothing to deposition compared to other mechanisms. When a crude oil is flowing in a conduit (porous media, well, pipeline, etc.) there is an additional effect (electrokinetic effect) to be considered in the behavior of its heavy organic constituents. This is because of the development of electrical potential difference could then cause a change in charges of the colloidal particles further down in the pipe, the ultimate result of which is their untimely deposition and plugging of the conduit. The factors influencing this effect are the electrical and thermal characteristics of the conduit, flow regime, flowing oil properties, characteristics of the polar heavy organic and colloidal particles, and blending of the oil. Thus the Lorenz forces are concerned it is difficult to explain the interaction between a magnetic field and a hypothetical crude which only contain only non-polar molecules. Paraffin clogging is also believed to result from a combination of magnetic and electrostatic forces resulting from friction in the flowing of oil in the oil conduit that contributes to the collecting of paraffin, salt and scale deposits on the inside of oil transmission lines. According to reference when crude is flowed in an adequate magnetic field paraffin molecules tend to align their poles with the ones of the magnetic field as far as thermal agitation is not excessive. Moreover, the action of magnetic field on these molecules changes both electron rotation and translation patterns thus changing their orbital angular momentum. This leads to a disturbance in the crystal agglomeration processes. As the result, under a given magnetic field, weak dipoles are actually brought into being in the paraffin molecules. These dipoles generate a repulsion force between these molecules leading to changes in their rheological and morphological properties. Nevertheless the lack of conclusive literature data on the effect of magnetic fields on the phase behavior of paraffins can be explained by the complex nature of crude, in which innumerable components, having different physical and chemical properties are found.

-Cylinder head plays the most important role in the working of engine, at elevated temperatures the engine will be overheated, which affects the performance of engine. This affect can be reduced by increasing the surface area of cylinder head without increasing the weight. This project involves in design and modification of four stroke petrol engine cylinder head, to increase the heat dissipation rate. In this the concentration was taken on the fins to increase the surface area. The cylinder head existing four fins are replaced with five fins without increasing the mass of the fins. Design of cylinder head was done by using CATIA software, which is advanced parametric design software, developed by Dasssults Systems. The model was designed in part module and drafting work was done in drafting module to show the dimensions with orthographic views. Analysis was done in the ANSYS Software, which works based on FEA. In this transient thermal analysis was done on the model before modification and after modification with different materials and for each material the results were compared, finally the appropriate material was suggested with design modification. In an automotive powertrain system, one of the most critical components is the cylinder head, which possesses the complicated mechanical structure coupled with a sophisticated combustion process. With the ever-increasing demand for higher engine power, the requirement for the cylinder head's loadbearing capacity is also increasing. In addition, lightweight design is also being pursued for the cylinder head, which is important for better fuel economy and vehicle safety.

Looking at the proceedings ofthe above symposium it becomes obvious that the participants were believers in the efficacy of lithium, and it is not surprising that one of them even thought of linking the lithium content of water to the frequency of manic-depressive states in different regions (p. 47). The idea of adding lithium to the natural water supply has of course been raised at other meetings, but only in a lighter vein. The clinical evidence presented is enough to provide an excuse for a believer to try lithium on any of his difficult patients, ranging from a i6-year-old neurotic brain-damaged girl (p. 22, case 7) to a 62-year-old man with the diagnoses of †̃¿ defectus mentalis' and schizophrenia (p. 35, case 3). Every participant at the conference seemed to accept its specific effect in manic depressive psychosis, and any patient who improved after lithium was suspected of being an atypical example of manic depressive illness. In only one paper were the authors bold enough to suggest that in certain cases of hyperactivity and uneasiness lithium has a completely unspecific sedative effect (page 39). To a non-believer most of the evidence is interesting, but not convincing. None of the trials were controlled, and only one author (p. 41) lists the patients to whom he prescribed lithium. In his series, cyclical manic-depressive psychotics showed the best response, but of the recur rent endogenous depressives less than half improved. Nevertheless, many important facts, useful to both believers and non-believers were presented at the symposium, for which we should thank our biochemical and pharmacological colleagues. I make no excuse for summarizing them:


By using an indirect method for determining the characteristic impedance of uniform transmission lines embedded in coaxial connectors, a novel two tier L-L de-embedding method is presented. The proposed de-embedding method is suitable for S parameters characterization of GaN HEMTs packaged transistors mounted on a symmetrical and reciprocal test fixture. In addition, the new technique does not presents the limitation exhibited by the Thru-Reflect-Line (TRL) in the low frequency range nor the limitation exhibited by the Thru-Reflect-Match (TRM) in the high frequency range. To validate the new two tier L-L de-embedding method, the S-parameters of a packaged GaN HEMT de-embedded with TRL are used. The good agreement between the DUT S-parameters obtained with both techniques, L-L and the TRL, validates the proposed L-L de-embedding method.

The failure of photovoltaic modules in high-temperature and high-humidity tests is generally caused by the loss of electrical contact between the cell emitter and finger metallization, due to the corrosion of the glass layer by the acetic acid which is generated by the hydrolysis of the ethylene vinyl-acetate copolymer that is used as the encapsulant. In this study, a high-temperature high-humidity test was conducted on a photovoltaic module—namely, a solar cell with reduced output—to examine the metallization–Si wafer interface. The results confirmed that Pb was eluted from the glass layer to form an alteration layer that inhibits electron movement from the emitter layer to the metallization, thereby decreasing the output of the module. The corrosion products generated from the eluted Pb indicated that the front-side metallization was statically exposed to the same environment inside the PV module as that in an aqueous solution of acetic acid.

Volume 12 "Governing the Unknown: Adaptive Spatial Planning in the Age of Uncertainty" of the peer-reviewed journal plaNext – Next Generation Planning comes as a product of the 2021 AESOP YA Conference that took place at Polis University (Tirana) during March 29 and April 2, 2021. This was the 15th conference of the YA network, aimed at fostering a welcoming environment for debate and peer-learning among students, young and senior researchers, and practitioners interested in urban planning studies. Being the first YA conference since the initiation of the COVID pandemic, it was organized in a hybrid format, with the organizers managing more than 50 participants remotely from Albania. Despite fewer spontaneous and informal meetings than in previous events, due to the limitations imposed by the hybrid format, the conference went smoothly and engendered insightful reflections that provided a tangible input for this special issue of PlaNext.


The formation of alkaline magmas observed worldwide requires that low degree-melts, potentially formed in the asthenosphere, were able to cross the overlying lithosphere. Fracturing in the upper, brittle part of the lithosphere may help to extract this melt to the surface. However, the mechanism of extraction in the lower, ductile part of the lithosphere is still contentious. Metasomatic enrichment of the lithospheric mantle demonstrates that such low-degree melts interact with the lithosphere, but the physical aspect of this process remains unclear.

Here, we aim to better understand, first, the percolation of magma in a porous viscous medium at pressure (P) and temperature (T) conditions relevant for the base of the lithosphere, and second, the impact of chemical differentiation on melt migration. We investigate theoretically the process of melt migration employing the fundamental laws of physics and thermodynamics. We simulate melt percolation numerically with a one-dimensional (1-D) Thermo-Hydro-Mechanical-Chemical (THMC) model of porosity waves coupled with thermodynamic results obtained from numerical Gibbs energy minimisation calculations. We perform THMC modelling and Gibbs energy minimisations with self-developed numerical algorithms using MATLAB and linear programming routines. We employ a simple ternary system of Forsterite/Fayalite/Enstatite for the solid and melt. Model variables, such as solid and melt densities or mass concentrations of MgO and SiO in solid and melt, are a function of pressure (P), temperature (T) and total silica concentration of the system (X). These variables are pre-computed with Gibbs energy minimisation and implemented in the THMC porosity wave transport code via parameterized equations, determining the T-P-X dependence of the model variables.

First results show that the total silica concentration and the temperature gradient are important parameters to consider in melt migration by reactive porosity waves. We discuss results of a systematic series of 1-D simulations and we present preliminary results form a 2-D reactive porosity wave model.


The alpaca is a camelid from the Andes of South America; it lives in the highlands of the Andean Plateau where temperatures during the night are below 0. Its fur is highly quoted for its unique characteristics of fineness and thermal capacity. It is mainly used to make clothes that are traded in the international market, especially in the United States and the European Union. Switzerland is a country that offers new sales opportunities for these products and the production of blankets to help overcoming the cold winter of the area is a productive and tempting business. The business plan is focused on the creation of a handcrafted production company of blankets made entirely by hand and with 100 percent alpaca fiber, which will be exported to Zurich and Geneva, where the largest Swiss population of high social stratum is located. After analyzing the market, it was determined that 80 percent of the population of these two cities have an income higher than USD 4,500, which allows them to purchase products of excellent quality, such as 100 percent natural alpaca fiber blankets, and handmade. In order to calculate how much our product will cost, the Van Westendrop method was applied, and it was set at USD 253. The strategy of internationalization is determined by the quality of the product. According to the study carried out, and considering the demands of the market, this strategy is essential. The strategy of differentiation in reference to similar products will be the handmade confection, and the pure raw material of alpaca, without mixtures of other fibers. The initial investment will be USD53.263, with a working capital of USD 43.830. The 62 percent of the total amount will be covered by own capital, equivalent to USD 33.263 and the remaining 38 percent by bank financing working capital USD 20,000 In order to determine the economic feasibility of the business plan, different financial analyzes projected to five years were made, getting the following results: ROI of 62 percent and ROE of 78 percent, these figures define the profitability expected for the shareholders just about their investment. The NPV will be USD 60.479,63 and the IRR of 59,63 percent for the investor; and the NPV will be of USD 43.779,59 with the IRR of USD 48,84 for the project investment.

Submitted for the MAR07 Meeting of The American Physical Society High Resolution Polar Kerr Effect Measurements of HighTemperature Superconductors: Evidence for Broken Time Reversal Symmetry Below the Pseudogap temperature1 ELIZABETH SCHEMM, JING XIA, WOLTER SIEMONS, GERTJAN KOSTER, MARTIN M. FEJER, AHARON KAPITULNIK, Stanford University — High resolution Polar Kerr Effect (PKE) measurements were performed on YBa2Cu3O7−δ as a function of temperature for variety of doping levels. In order be able to measure effects beyond our old search for anyon superconductivity, we devised a new technique based on a fiber Sagnac interferometer with a zero-area Sagnac loop. With this technique we show a shotnoiselimited sensitivity of 100 nanorad/ √ Hz with incident photon power of ∼ 10 μ-Watt, in a wide temperature range from 0.3 K to room temperature. Our results indicate that a Time Reversal Symmetry Breaking (TRSB) signal appears in all underdoped YBa2Cu3O7−δ samples below the doping dependent pseudogap temperature. The effect increases with decreasing temperature and seems to saturate at a lower temperature close to Tc. The saturated size of the effect increases with increasing δ. We will discuss possible origins of this effect and its presence in other high-Tc superconductors. 1This work was supported by Center for Probing the Nanoscale, NSF NSEC Grant 0425897 and by the Department of Energy grant DEFG03-01ER45925.

The enhanced backscattering or weak localization of light in the laser light scattered multiply from highly disordered media has attracted a great deal of attention as a visual precursor of the Anderson localization. It is known that the constructive interference between the waves travelling along the time-forward and the time- reversed paths produces the intensity peak in the direction of retroreflection, depending on the polarization of scattering light, the particle size, the fraction of solution and so on' ). The remarkable spatial properties of the enhanced backscattering reflects on the temporal ones. It was experimentally shown that the temporal correlation function of backscattered light varies with the scattering angle depending on the polarization2'3). We investigate the dependence of the temporal correlation of the enhanced backscattered light on both the polarization of scattering light and the particle size of solution by considering its relation with the spatial properties. Investigations are conducted from the theoretical analysis based on the diffuse approximation, a Monte Calro simulation and an experiment. We demonstrate the remarkable spatial variation of the relaxation time depending on the direction of the polarization and the particle size.


Abstract . In the work, a method is developed for optimal tuning of PI-controllers with constraints. The method is based on reducing the tuning problem to the unconstrained optimization problem. In order to reduce the problem, a special complex criterion has been proposed. It is characterized by the desired topological properties. The latter have been obtained using weight coefficients that take into account the requirements for system stability, constraints and a set of criteria that reflect undesirable controlling indicators. The predetermined topological properties of the criterion made it possible to find its global minimum. In the work, a modification of the ME-PSO particle swarm method has been used. It is characterized by reinitialization of the swarm in the stage of stagnation. In order to show the effectiveness of applying the method, the coefficients of the PI controller with the constraint on overshoot (it is assumed that it should be zero) have been calculated. The optimization criterion was the settling time. As a result, it was found that for four test transfer functions (second and third orders, one transfer function corresponds to an object of regulation with a time delay), the settling time is significantly decreased while ensuring overshoot constraint. The obtained results were compared with those that correspond to the controllers that are tuned using other (known in engineering practice) PI-controller tuning methods (compared methods allow to obtain zero overshoot). In addition, the analysis of the quality of controlling was carried out using indicators: mean integral error and mean integral control. The developed approach is quite universal. It might be used for the synthesis of optimal control systems, including non-linear ones. Keywords: controller, optimization, criterion, constraints, tuning, particle swarm optimization


A system of global networks were used and built by the nineteenth-century British mission movement. This article offers examples of these global networks and examines their significance and the reasons these global networks are overlooked in existing histories of missions. This brief examination concludes that while global networks of information gave missionaries a broadly contextualized view of their mission fields, it also clouded their judgment about local issues and affairs.

Curcumin is a natural polyphenol extracted from the rhizome of Curcuma that has an important antitumour effect, but its effect on adverse psychological stress‐induced tumour proliferation and invasion has not been reported to date. Here, we found that curcumin not only inhibited the growth of xenografts in chronically stressed nude mice, but also decreased the expression of matrix metalloproteinase (MMP)‐2/9 and CD147 in tumour tissues. Exogenous norepinephrine (NE) was used to stimulate glioma cells to simulate the stress environment in vitro, and it was found that curcumin inhibited the NE‐induced proliferation and invasion of glioma cells in a dose‐dependent manner. Further research found that the effects of NE on glioma cells could lead to the activation of the mitogen‐activated protein kinase (MAPK) signalling pathway through β‐adrenergic receptor, while curcumin suppressed the level of extracellular signal–regulated kinase (ERK)1/2 phosphorylation. In addition, blocking ERK1/2 expression with U0126 resulted in the down‐regulated expression of CD147, which further led to the decreased expression of MMP‐2 and MMP‐9. Curcumin could also inhibit the expression of cyclin D1/CDK4/6 and anti‐apoptotic protein Bcl‐2/Bcl‐XL induced by NE, and induced cell cycle changes and increased apoptosis. Therefore, curcumin may be a potential candidate drug for preventing and treating the progression of glioma induced by adverse psychological stress.


Fresh weight reductions of greenhouse-grown soybeans and corn treated with post-emergence thifensulfuron at 4.4 g ai ha−1 were synergistically enhanced when the herbicide was mixed with formulated chlorpyrifos or malathion insecticides, but the enhancement was not observed with formulated methomyl insecticide. Thifensulfuron plus formulants of either chlorpyrifos or malathion reduced fresh weights no more than did the herbicide applied alone. Growth rate of hydroponically grown soybeans was reduced by root-applied thifensulfuron in combination with a foliar-applied formulation of chlorpyrifos or malathion, but not methomyl. Postemergence-applied thifensulfuron reduced the growth rate of hydroponically grown soybeans and corn with chlorpyrifos, malathion, or methomyl applied postemergence 1 d before thifensulfuron and with procedures identical to those used for absorption, translocation, and metabolism experiments. None of the insecticides applied 1 d before thifensulfuron altered foliar absorption of 14C-thifensulfuron or its translocation in unifoliolate soybeans or three-leaf corn. Thin-layer chromatography of soybean extracts revealed one primary thifensulfuron metabolite, presumably the deesterified free acid. 14C-thifensulfuron metabolism in corn produced about five unidentified metabolites in appreciable amounts. Levels of unmetabolized 14C-thifensulfuron 24 h after herbicide application were highest in insecticide-treated soybeans and corn. Over all experiments, enhancement of injury and inhibition of thifensulfuron metabolism generally were greatest in soybeans with chlorpyrifos but were greatest in corn with chlorpyrifos or malathion. Synergistic enhancement of thifensulfuron injury to soybeans and corn by chlorpyrifos and malathion appears to result from insecticide inhibition of thifensulfuron detoxication.

Tumor cells that have acquired resistance to gefitinib through continuous drug administration may complicate future treatment. To investigate the mechanisms of acquired resistance, we established PC-9/ZD2001, a non-small-cell lung cancer cell line resistant to gefitinib, by continuous exposure of the parental cell line PC-9 to gefitinib. After 6 months of culture in gefitinib-free conditions, PC-9/ZD2001 cells reacquired sensitivity to gefitinib and were established as a revertant cell line, PC-9/ZD2001R. PC-9/ZD2001 cells showed collateral sensitivity to several anticancer drugs (vinorelbine, paclitaxel, camptothecin, and 5-fluorouracil) and to tumor necrosis factor α (TNF-α). Compared with PC-9 cells, PC-9/ZD2001 cells were 67-fold more sensitive to TNF-α and PC-9/ZD2001R cells were 1.3-fold more sensitive. Therefore, collateral sensitivity to TNF-α was correlated with gefitinib resistance. PC-9/ZD2001 cells expressed a lower level of epidermal growth factor receptor (EGFR) than did PC-9 cells; this down-regulation was partially reversed in PC-9/ZD2001R cells. TNF-α-induced autophosphorylation of EGFR (cross-talk signaling) was detected in all three cell lines. However, TNF-α-induced Akt phosphorylation and IκB degradation were observed much less often in PC-9/ZD2001 cells than in PC-9 cells or PC-9/ZD2001R cells. Expression of the inhibitor of apoptosis proteins c-IAP1 and c-IAP2 was induced by TNF-α in PC-9 and PC-9/ZD2001R cells but not in PC-9/ZD2001 cells. This weak effect of EGFR on Akt pathway might contribute to the TNF-α sensitivity of PC-9/ZD2001 cells. These results suggest that therapy with TNF-α would be effective in some cases of non-small-cell lung cancer that have acquired resistance to gefitinib.


The data of the Turkish Esophageal Atresia Registry (TEAR) was evaluated to define the survival rate and risk factors of mortality in infants with esophageal atresia (EA).

 The data of 389 cases registered by 23 centers between 2014 and 2018 were evaluated for demographic features, associated anomalies, surgical treatment and mortality-related outcome. Each parameter was evaluated for cases with mortality (CM) and compared with the results of survivors. Also, prognostic factors were investigated in CM.

 The overall survival rate was 81.09% and the mortality was 19.02% (n = 74). The male/female ratio was 1:1 in CM and 1.2:1 in survivors. The mean weight and height measurements in CM were lower than in survivors (1956 ± 658 g- 43.2 ± 5.7 cm vs 2534 ± 609 g-46.4 ± 4.3 cm) (P < 0.05). The incidence of associated anomalies was 90.6% in CM and significantly higher than survivors (59.6%) (P < 0.05). Neurological, cardiovascular, vertebral, and extremity anomalies were significantly higher in CM (P < 0.001). The most common type of anomaly was EA with distal fistula 89.2% in CM and 74.6% in survivors. The rate of primary anastomosis was also significantly lower in CM (67.6% vs 84.3%, P < 0.05). The gap length did not show statistical difference between CM and survivors (P > 0.05). Tube feeding was more common in CM and the incidence of full oral feedings was significantly higher in survivors (P < 0.01). According to the Spitz classification, the survival rate was 87.1% in Class I, 55.3% in Class II, and 16.7% in Class III. The most common causes of mortality were associated with cardiovascular disease, pneumonia, and sepsis.

 The majority of national TEAR data comes from tertiary healthcare centers in Turkey. Therefore, the slightly increased mortality rates could be related to the inclusion of more complex and complicated cases. Birth weight–height, associated anomalies, and Spitz classification are significant risk factors of mortality in cases with EA.


Objective To investigate the effects of Ginsenoside Rg3 on the hypertrophic scar of rabbit ears in the early phase of scarring.Methods The rabbit ear model was established on the 12 New Zealand white rabbits.The rabbits were divided into 6 groups(n=2): group B(control group),group T0(only NS),group T1(GS-Rg3 1 mg/mL),group T2(GS-Rg3 2 mg/mL),group T3(GS-Rg3 3 mg/mL),group T4(GS-Rg3 4 mg/mL).0.1 mL GS-Rg3 with different concentration were injected at wound in each group from 1 day after operation.The wounds healing times and hypertrophic scar were observed.Scar samples were harvested 28 days after operation.The calculation of HI index and collagen density by HE,Masson staining,VEGF content was detected by ELISA and Hpr content was also detected.Results The expression of VEGF,HI index,collagen density and the Hpr content were significantly lower in group T1-T4 compared with group B and group T0(P0.05).There were no significantly differences between group T1-T4.Conclusion Topical injection of ginsenoside Rg3 in the early phase of trauma can inhibit the activity of angiogenesis and the formation of collagen in a rabbit ear model,thus reduced hypertrophic scar formation.The findings of this study may have clinical implications on the management of human hypertrophic scars.


This study examined the day caring methods among the civil servants of reproductive age with children betweenthree months to four years in Lagos State Nigeria. The research design employed for this study was a descriptiveresearch design. A total number of 212 teachers and 128 ministry workers making a total of 340 reproductive agemothers were purposively selected from the State. A self-structured questionnaire was used to collect informationfrom the respondents. Accidental sampling technique was adapted to survey the respondents for this study. Datawere analyzed using frequency distribution, simple percentages and inferential statistic of t-test analysis. The resultsof the study revealed that 30 (8.8%) teachers and 33 (9.7%) ministry workers agreed that they kept theirchild/children in creche. The study showed that 188 (55.3%) teachers and 92 (27%) ministry workers agreed thatthey wanted to have time to care for themselves, while 204 (60%) teachers and 38 (11.2%) ministry workers agreedthat they liked to get back to their work and be efficient. It was also revealed that a reasonable proportion of theteachers agreed that there were adequate personnel and adequate rooms for learning, while the ministry workersdisagreed. The results further showed that many of the day care workers were not well educated. Based on thefindings, it is recommended that the civil servants should be educated on the need to adopt the modern and educativemethods of day care.

transition metal salts mediated oxidative radical addition of ethyl acetoacetate to limonene produced chemoand regiospecificaly (rR,5RS)-3-carboetho\>-2,5-dimethyl-5-(4'-methylcyclohexen-3-enyl)-4>5-dihydrofiiran as a 1:1 mixture of diastereoisomers. The best yield (72 % isolated) was obtained using limonene (1 mol equiv.), ethyl acetoacetate (1 mol equiv.) and Mn(0Ac)3«2H20 (2 mol equiv.) in acetic acid at 70°C. The utilisation of cerium(IV) ammonium nitrate (CAN) or Co(OAc)2 instead of Mn(III) led to lower yields of the dihydrofurans along with diethyl 2,3-diacetylsuccinate. Fe(III) salts gave a complex mixture of products and using CuCl2 there was no reaction.


Silicon nitride (Si3N4) has been utilized as a nanofiller in polymeric insulation due to its good characteristics in both electrical insulation and thermal conduction properties. In this work, a comparative study was performed between unfilled polyethylene and polyethylene containing different amounts of Si3N4 nanofiller. The study showed that the low density polyethylene (LDPE) added with 15 wt% of Si3N4nanofiller could have higher breakdown strength compared to equivalent LDPE with 10 wt% of Si3N4nanofiller. Morphological characterizations of the nanocomposite samples were performed using field emission electron microscopy (FESEM) and the results showed that the breakdown performance of the investigated materials were affected by the agglomeration of Si3N4 nanoparticles.


This study pertains to the design optimization of a four-blade ceiling fan to enhance air circulation and energy efficiency. The sweep angle of the blade profile is nonlinear. The design of experiment (DOE) computational fluid dynamics (CFD) and response surface method (RSM) methods were used in parallel to find the optimal design solution. The design variables considered were inboard angle of attack, outboard angle of attack, blade sweep, and tip-chord length. Numerical simulations were conducted using steady state Reynolds-averaged Navier–Stokes (RANS) equations and the Spalart–Allmaras turbulence model. The baseline results were validated through experimental data. Subsequently, the DOE method was employed to generate the blade design which reduce the number of simulations without losing the influence of different geometric parameter interactions. The response variables studied were volume flow rate, mass flow rate, torque, and energy efficiency. The simulations exhibited that flow pattern has a distinct feature and is further classified into three groups. In the end, the optimal blade design was identified using response surface methodology (RSM).

A composite wavelet transform is defined and conditions for stable signal recovery are characterized. Frames for the space of finite energy signals then arise as discrete families of composite wavelets. These wavelet-type frames incorporate advantages of both the short-time Fourier transform and the continuous wavelet transform and are signal adaptive. As with the time-frequency atoms in work of Mallat and Zhang, the composite wavelets can be used to analyze competing signal structures. The added frame condition provides extra numerical stability.<<ETX>>

Actions that are intended to be more nature and environment friendly currently appear to be on the increase and seem to work towards clearly defined and deliberately applied objectives. In France, the refusal to use poisoning as a means to combat the proliferation of some species of animals (coypus and muskrats) may be seen as part of this recent trend. The priority that has just been given to trapping actually aims at a better protection of threatened species and the environment in general. The implementation, and indeed the interpretation, of this new emphasis on trapping is, however, far from obvious. In order to better understand it, we have chosen to examine is as a process of "ecologisation", i.e. as a form of recomposition and reforming of the ties between society, nature and technology. In doing so, we propose to enrich the concept by highlighting a process that stems from peculiar and unforeseeable stories, which is neither simple nor natural and which is underpinned by material objects playing the role of concrete vehicles for change. This article is based on documentary research and on 70 interviews conducted with the persons responsible for the new collective structures that have been taking shape in France to combat the proliferation of the coypu and muskrat.


This paper attempts to address the issue of hardening the internal security of an organisation's network by easing its patch management. Traditionally security has been modeled on a "hard outer shell" approach, with a firewall protecting the otherwise vulnerable internal network. With the advent of worms using such techniques as social engineering to bypass the organisational firewall and installing trojans, this approach is no longer sufficient. As a result of these new attacks, emphasis should be placed on improving the security of the internal network. Most research agrees that prompt patching of security vulnerabilities would significantly reduce the vulnerability of these machines. However, this requires system administrators not only to keep abreast of the flood of patches, but to ensure they are deployed to every machine, in what could be a very large network. These difficulties are worsened by problems the patches themselves often create. This is a difficult task and the failure of system administrators to perform it is echoed in the recent spate of worm attacks, with some taking advantage of vulnerabilities for which patches had been released up to six months earlier. To cope in this environment an organisation needs a comprehensive patch management policy. A technology agnostic view of this policy is described in order to better understand what is required of an automated solution. A few vendors have released tools to find vulnerabilities, find patches and distribute them, the best known example of which is Microsoft's Software Update Service. However, these tools are generally inflexible, expensive and only deal with a limited part of the patch management process. This paper seeks to discuss the implementation of an open source, cross platform tool to solve this problem. This will involve discussions in four areas; the need for such a system, the patch management process, existing systems, and the proposed solution. The proposed system architecture is then broken down into four areas; sourcing patches, patch packaging, testing patches, patch distribution and the development of the system. The first area will discuss how to pull patches from multiple vendors such as Windows Update, Symantec AV, FreeBSD ports and ISC. The second will involve discussion on creating packages; whether to replace entire binaries, to employ binary patching techniques or to use source distribution. The third section will discuss how this tool can improve testing and provide stop-gap measures for protecting the organisation during the testing process through the use of IDS signatures. The fourth section will discuss methods of distributing these packages, such as direct download or peer-to-peer implementations like Bittorrent. The last section will discuss a modular, platform-independent implementation of the system.


Two X-ray-induced mutants, Large Pod (TG1) and Virescent, of the variety Spanish Improved, were crossed and selection was made in the progenies for improved oil content. Seven F6 selections, designated TG7 to TG13, were included in field trials in 1969-1971. Compared with the control varieties, they matured 6-10 days later, suffered less from pod loss because of a 15-25-day seed dormancy, and gave 27-46% higher yield of pods. The selections also showed a 10-60% higher 100-kernel weight and a 2-4% higher oil content.
