We have used data collected with the Sea Beam system to produce a detailed regional bathymetric map of the medium to fast slipping (90 mm/yr) Orozco Transform Fault. The morphotectonic fabric of the 90 × 50 km transform domain is spatially heterogeneous and is composed of relatively shallow areas ( 3200 m). The plate boundary geometry is clearly identified morphologically and is characterized by a series of linked basins and troughs that approximate a zed pattern in plan view. East-west trending basins define the northern and southern boundaries of the transform domain, and these troughs are thought to mark the location of strike-slip tectonism. A central, north-south trending ridge with an axial valley, called here the Mid-Orozco spreading center, is thought to represent a short (30 km) ridge segment that links two transform faults. Morphotectonic relationships developed along the southeastern flank of the survey area suggest that this plate boundary geometry has recently become unstable and is presently undergoing a transformation as the tip of the East Pacific Rise axis propagates northward across the transform domain bypassing the Mid-Orozco spreading center. If the southern ridge axis continues to propagate northward it will link with the aseismic extension of the northern strike-slip strand and the present-day plate boundary will evolve into a simple ridge-transform-ridge (R-T-R) geometry with an offset of approximately 70 km.


The paper outlines space law as it currently stands and sets forth the arena in which such law has been negotiated. Note is taken of the flexibility set forth in these negotiated treaties and the fact that the treaties provide the necessary framework for the development of cooperative space activities in the future.


Because of academic, scientific and social variables the examination of the different behaviorisms categories is necessary in an epistemological framework. This article presents a comparison between J. R. Kantor's Interbehaviorism and B. F. Skinner's Radical Behaviorism. The questions from which these authors postures are identified and their historical evolution are: (1) ?What is knowledge?, (2) ?What is known?, (3) ?How do we know?, (4) ?The what for of knowledge?, and (5) ?What are the criteria of valid knowledge? The analysis lead to conclude that, leaving their different work guidelines apart, both authors shared interests respect to psychology as ascience ofbehavior, and both ofthem coincided in epistemological and ontological foundations thathave facilitated new behaviorisms development, like empirical behaviorism and contextual functionalism.


The purpose of this article is to develop and validate a computational method for the solution of viscous incompressible flow in a domain with specified static or total pressure on the flow-through boundaries (inflow and outflow). The computational algorithm is based on the Finite Volume Method in nonstaggered boundary-fitted grid. The implementations of the boundary conditions on the flow-through parts of the boundary are discussed. Test examples illustrate the main features and validity of the proposed method to study viscous incompressible flow through a bounded domain with specified static pressure (or total pressure) on boundary as a part of well-posed boundary conditions.


Background. Somatic disease often causes psycho-emotional distress, reflecting the intensity of mental distress and the state of psychological adaptation person to a stressful situation.
Objective – to study the characteristics of the psychoemotional state and cognitive functioning in patients with cerebrovascular pathology at different stages of development in relation to the level of stress risk.
Materials and methods. At Kharkiv Regional Clinical Hospital – Emergency and Emergency Medicine Center during 2016-2018, observed 383 patients with cerebrovascular pathology on different stage of diseases and 47 healthy persons. In research we used Symptomatic questionnaire by Alexanrovich, "Lifestyle Analysis" test and MOCA.
Results. The high level of stress risk in patients with cerebrovascular pathology combined with an increasing of psychoemotional distress and a change in the structure of psychopathological symptoms. In patients with cerebrovascular pathology found growth psychopathological manifestations along the axis of stress risk and the axis period of the disease, which determines the health centered lifestyle and somatic disease as important factors of mental distress. Increased stress is combined with a cognitive impairment. The growth clinical manifestations of cerebrovascular disease and especially the state after a stroke accompanied with a cognitive impairment as a result of brain injury.
Conclusions. Investigation of the psycho-emotional and cognitive function state in connection with level of stress risk is important for the development of a complex psychological help for patients with cerebrovascular pathology based on a health-centered approach.


The aim of this study was to evaluate the shelf life of four commercial formulations pork sausage (Control - no added additive, F1 - added 3% sodium lactate, F2 - added 0.5% nisin and F3 - added 3 % sodium lactate and 0.5% nisin). The samples were distributed into polyethylene bags containing 200 grams for each day of storage and formulation for subsequent bacteriological and physicochemical analysis. All formulations were vacuum packed and stored at 4°C. Regarding the shelf life samples were submitted to the following bacteriological counts of heterotrophic bacteria aerobic mesophilic and psychrotrophic; count of lactic acid bacteria count and Enterobacteriaceae. The analyzes were carried out physico-chemical: pH, water activity and the content of thiobarbituric acid reactive substance. Interpreting the results obtained in the experiment it was concluded that the use of a combination of 3% sodium lactate and 0.5% nisin increased the shelf life compared to other samples. Key words: natural antimicrobial, bacteriocin, storage and pork sausage filling.


The size of the bony jugular foramen has been measured in 100 children with congenital hydrocephalus and myelomeningocele. It was found that the size of the foramen does not differ significantly from that in children without hydrocephalus. There is thus no indication of a bony obstruction to the jugular venous outflow from the skull in hydrocephalic children.


Background: The aim of this study is to explore the relationship of various demographic factors in women presenting with menorrhagia and to evaluate the etiology and diagnosis of menorrhagia. Materials and Methods: All women of 15-45 years age group with complaint of menorrhagia attending the Gynaecology clinic at Alluri Sitarama Raju Academy of Medical Sciences, Eluru during the period of two years from July 2009 to June 2011 are included in the study after informed consent is obtained and analyzed. Results: A total of 800 patients were analyzed. About 71% of the women are above 30 years, 77% are of low socio economic group , 46% are illiterate and the prevalence of menorrhagia decreases as the education status improves. More than half of the women are housewives and menorrhagia is least common in working women accounting to only 3%. About 41% are with more than the required BMI. 23% are unmarried and most of them are with 20 to 30 yrs of marital life including 60% multiparous women and 60% sterilized. 35% of the women presented with Hb% <8gm/dl and 5% had blood transfusions. The most common structural abnormality found on USG being fibroid uterus and the most common histopathology finding being normal endometrium followed by simple endometrial hyperplasia without atypia with cervical changes in 13%. Conclusions: According to our experience, menorrhagia is influenced by various demographic factors like age, educational status, occupation and socioeconomic status. Menorrhagia is more common in women of greater than 30 yr age group belonging to low socioeconomic status. Most of them are illiterates who are either housewives or daily wage workers. This clearly shows the low literacy rates, and type of work associated with menorrhagia which strongly implicate the necessity of improving the literacy rate. Its prevalence is not much influenced by BMI. And most of the women are multiparous and sterilized. Introduction The word 'MENORRHAGIA' is derived from the greek words 'MENO' meaning uterus and 'RHEGNUNAI' meaning to burst forth. Infrequent episodes of menorrhagia usually do not carry severe risks to women's general health. Menorrhagia is defined as excessive uterine bleeding occurring at regular intervals or prolonged uterine bleeding lasting more than seven days. The classic definition of menorrhagia (i.e., greater than 80 mL of blood loss per cycle) is rarely used clinically. Menorrhagia is a common complaint. While menorrhagia remains a leading reason for gynecologic office visits, only 10-20% of all menstruating women experience blood loss severe enough to be defined clinically as menorrhagia. Approximately 5% of females seek medical attention for this condition. In recent years, there has been increased recognition of the scope and significance of gynaecological problems experienced by poor women in developing countries. The World Health Organization reports that 18 million women aged 30-55 years perceive their menstrual bleeding to be exorbitant. Reports show that only 10% of these women experience blood loss severe enough to cause anemia or be clinically defined as menorrhagia. In practice, measuring menstrual blood loss is difficult. Thus, the diagnosis is usually based upon the patient's history. Population studies show that the typical menstrual blood loss is 30-40ml, and that 90% of women have losses of less than 80ml Heavy menstrual flow that interferes with regular lifestyle. Menorrhagia must be distinguished clinically from other common gynecologic diagnoses. These include metrorrhagia (flow at irregular intervals), menometrorrhagia (frequent, excessive flow), polymenorrhea (bleeding at intervals <21 d), and dysfunctional uterine bleeding (abnormal uterine bleeding without any obvious structural or systemic abnormality). Aim: The aim of this study is to explore the relationship of various Demographic factors in women presenting with menorrhagia and to evaluate the etiology and diagnosis of menorrhagia. Materials and methods: Study Group: All women of 15-45 years age group with complaint of menorrhagia attending the Gynaecology clinic at Alluri Sitarama Raju Academy of Medical Sciences(ASRAM), Eluru during the period of two years from June 2009 to May 2011 are included in the study after informed consent is obtained and analyzed. Methodology: Clinical information pertaining to demographic data, complete medical history with attention to menstrual history is taken and the proforma is filled. Additional important information includes prior pregnancies and contraceptive method, medications, social history (including domestic violence and assault), and review of systems (general well-being, gastrointestinal and genitourinary symptoms). The physical examination include vital signs and abdominopelvic evaluation. Tests include a urine pregnancy test, Pap smear. In addition, endometrial biopsy performed on women over age 35 with abnormal bleeding to rule out endometrial hyperplasia. Serum testing includes complete blood count, Prothrombin/ partial thromboplatin times, thyroid stimulating hormone, prolactin, follicle stimulating hormone, LH if due.

Seventy percent of US Department of Defense training and testing areas is on arid and semiarid land. Testing and training activities are often more devastating to arid lands than more mesic areas and, consequently, can threaten the continuation of military testing and training operations in these areas. Current gaps exist in diagnostic capabilities to distinguish among various degrees of sustainable and nonsustainable impacts from earth-disturbing activities in desert ecosystems. Work is ongoing to develop innovative remote sensing techniques to rapidly characterize impacts of military training and testing on arid environments. The diagnostic techniques include new rapid detection methods of image collection and laser induced fluorescence imagery techniques to provide early detection of the condition of stressed plants. Innovative image processing techniques will be assessed which will provide rapid assessment of vegetation parameters used in various US Department of Defense environmental management models such as the Army Training and Testing Area Carrying Capacity. New and cost-effective techniques for revegetation of disturbed training lands will be examined at Fort Irwin--the National Training Center in the Mojave Desert of California.


In order to develop a novel diagnostic technique, as an adjunct modality to SDT, that uses the gallium-porphyrin derivative ATX-70 as a sonosensitiser mediated by a chemiluminescent probe to produce sonochemiluminescence (SCL) for imaging and localization of cancer within tissue in vivo. The fluoresceinyl Cyprodina luminescent analogue (FCLA) was used as an optical reporter for singlet oxygen generated from the sonosensitisation reaction of ATX-70 in the model solutions and in the in vivo nude mice bearing mammary cancer. The sonosensitized chemiluminescence from the reaction of FCLA with 1O2 was detected by a highly sensitive light-detector. The effect of FCLA with different doses on cell viability was also assessed with MTT assay. The results showed with the FCLA as the reporter, there is clear evidence that the aqueous solution of ATX-70 exposed to ultrasound forms 1O2 in the system. In the in vivo experiments, the tumor-bearing mice are imaged with a great contrast during sonosensitization of ATX-70 mixed with FCLA as the SCL probe. No significant cytotoxity was detected at the different FCLA doses. The results indicated that a novel cancer imaging method, named as the sonodynamic diagnosis (SDD), can be established by the sonodynamic action with the assistance of SCL probe. Therefore, this technique could have potential applications in the clinical diagnosis of cancer diseases at an early stage, and can be used to assess the treatment efficacy during the sonodynamic therapy of cancers.

Sig. (2-tailed) = 0.000, so Sig. (1-tailed) = 0.000//2 = 0.001. 0.001 < 0.05. So it can be concluded that students skill to write narratives thematically who received learning using the problem base learning method based on mind mapping was better than students who received conventional narrative learning as a whole.


Objective
To investigate the status and influencing factors of family burden for non-hospitalized patients with breast cancer.

Methods
General information of the patients, family burden scale of disease (FBS) and family APGAR index questionnaire were used to carry out the cross-sectional study in 201 patients with breast cancer and their care givers in Affiliated Longhua Hospital, Shanghai University of Traditional Chinese Medicine from March to April, 2016.

Results
Total score of FBS for the 201 breast cancer patients was (23.03±10.77) points; scores of dimentions of economic burden, daily activities, recreational activities, family relationship, physical health, mental health were (1.26±0.57), (0.95±0.49), (0.87±0.55), (0.75±0.52), (0.82± 0.52), (0.92±0.60) points, respectively. Univariate analysis showed that FBS scores of different gender, age, educational level, occupation, marital status, course of disease, surgery, tumor grade, family care were different (P<0.05); multiple stepwise regression analysis showed that cancer classification, educational level , family APGAR index would affect FBS score which could explain 36% of the total variation of the family burden. Correlation analysis showed that the patients' family care and family burden were negative related (r=-0.485, P<0.01).

Conclusions
Family burden of non-hospitalized patients with breast cancer is at moderate level. Educational level and tumor grade are independent factors affecting breast cancer patients' family burden. The family burden of the breast cancer patierrts is related with their family care.

Key words:
Breast neoplasms; Family burden of disease; Family care degree; Influencing factors


THE CHIEF IMPROVEMENT in the redesigned coagulator is the selfcleaning switch. Of greater importance is the use of the new nickel-cadmium rechargeable cell. This is the battery used in shavers and tooth brushes. This cell fits into the old coagulator, but one should also obtain new tips. The nickel-cadmium battery is capable of delivering a heavy current for a prolonged time without losing voltage therefore it became feasible to design a tip that can be used as an actual cautery. This tip is colored red. It can be used in the office for Zeigler puncture of the lower lid, removal of growths of the lids, and so forth. A much cooler tip (blue-colored) is recommended for coagulation or mild cauterization in scleral wounds or the control of bleeders on the eyeball. This tip is ideal in the office for "drying up" conjunctival cysts and conjunctival nevae. When the latter are "brushed" by this blue tip right up to the limbus the tissue will shrink temporarily but no bandaging is required. In about six weeks the conjunctiva is as transparent as ever and no pigment will be seen. If any pigment areas remain of course they can be retouched. A third tip is capable of greater heat than the blue one but far less than the cautery tip. This one is color-coded green and is useful in handling bleeders in muscle surgery. The tip I am passing around with the instrument is for transillumination. It is readily sterilizable and can be kept on hand in the sterile state in case one wants it in a hurry. Since the coagulator is on the instrument table most of the time, it means there is a transilluminator at hand without the bother of wires. Of more common use, however, is the application of the transilluminator to the cornea as an aid in the placing of the limbal section in peripheral iridectomy. This was ably


Although "urine testing" is said to enable the male equid to assess the sexual status of the mare, there are no reports in the literature of any detailed study of this behavioural response of the stallion. Behavioural response to conspecific urine was studied in two horse stallions and one donkey stallion. The relevant nasopalatine anatomy is described. Events observed during urine testing included head, neck, lip, jaw, tongue movements, penile changes and nasal secretion. Nasal endoscopy indicated that the source of part of the nasal secretion was the secretory glands of the vomeronasal organ complex. The significance and probable function of these events in urine testing is discussed.


ABSTRACT We design here a finite-dimensional feedback stabilising Dirichlet boundary controller for the equilibrium solutions to parabolic equations. These results extend that ones in Barbu (2013), which provide a feedback controller expressed in terms of the eigenfunctions φj corresponding to the unstable eigenvalues of the operator corresponding to the linearised equation. In Barbu (2013), the stabilisability result is conditioned by the require of linear independence of , on the part of the boundary where control acts. In this work, we design a similar control as in Barbu (2013), and show that it assures the stability of the system. This time, we drop the require of linear independence and any other additional hypothesis. Some examples are provided in order to illustrate the acquired results. More exactly, boundary stabilisation of the heat equation and the Fitzhugh–Nagumo equation.


E-mail: email@example.com September 11, 2014, Accepted October 8, 2014Nuclear factor-erythroid 2-related factor 2 (Nrf2) regulates the expression of over 200 genes of antioxidant andphase II drug-metabolizing enzymes, and is highly expressed in non-small cell lung cancer (NSCLC). Ninederivatives of 4-(2-cyclohexylethoxy)aniline were designed. Our previous study demonstrated that IM3829increases radiosensitivity of several lung cancer cells in vitro and in vivo. Here, biological effects of IM3829derivatives ( 2a-2i) were evaluated. Compound 2g derivative effectively inhibits mRNA and protein expressionof Nrf2 and HO-1. In addition, we observed over two fold enhancement in IR-induced cell death, from2.90 ± 0.22 to 6.02 ± 0.87, in H1299 cancer cell-line. Among the nine derivatives, compound 2g derivativeexhibited the highest enhancement of radiosensitizing effect via inhibition of Nrf2 activity. Key Words : Radiosensitizer, Nrf2 inhibitor, Reactive oxygen species, Radiotherapy, Free radicalsIntroductionRadiotherapy is an effective treatment modality for solidtumors that can accompany surgery. The dosage of radio-therapy on the tumor is limited due to the side effects on thesurrounding normal tissues. On the other hand, fractionatedionizing radiation (IR) can lead to acquisition of radio-resistance cancer cells, which results in decreasing treatmentefficiency. Therefore, efforts have been made to developradiosensitizer or combination therapeutic agents with en-hanced efficacy of radiotherapy. Cancer cells harbor highly developed antioxidant systemsto maintain redox homeostasis that ensures cell survival withaberrant metabolism.


Developing countries suffer from the increase in accident rates and the corresponding number of fatalities and injuries. This is directly related to the overall culture of the people; including discipline, sense of responsibility, perfecting what people do. Therefore, the human factor is the major reason for the increased number of fatalities in developing countries. Furthermore, poor planning of infrastructure requires doubling the effort to overcome the human factors. Add to that the undisciplined traffic caused by the lack of police supervision, since the feel of supervision is part of the enforcement. In addition, the human factor is indirectly responsible for driving as well as the participation of the vehicle as a major factor in road accidents. This is mainly because the human factor is needed for proper maintenance of the vehicle including steering, suspension, tires, lights, wipers, etc. The maintenance concept is key to increasing the level of safety and reducing the impact of vehicles on accidents rates. Additionally, the problem of poor road planning, such as constructing roads next to waterways, requires expensive and advanced passive measures. Also, traffic accidents increase due to excessive speeding, which is caused by the lack of enforcement and responsibility to one's life and the lives of others. Therefore, road safety managers face a tremendous task since most of the road accidents are due to irresponsible human factors, not to mention randomness in entering and existing highways. It has to be noted that, the accumulation of incorrect road designs and ignoring proper road safety audits during road planning, and the slow-action in taking proper steps in response to road safety audits are amongst the main reasons for traffic accidents. Furthermore, the effectiveness of traffic measures is very important to lowering the number of accidents. Improper traffic measures can be caused by the accumulation of dust and sand on the road, which cause road markings to soil and disappear. Add to that the improper behavior of drivers who drive on top of a road marking, thus reducing its effectiveness as well as its life span. For example, a road in an agricultural area needs to be remarked after 2 to 3 months after marking operations due to bad driving habits, especially by tractors crossing these roads with muddy tires. These non-typical problems require non-typical solutions such as the use of cheap, non-recyclable material for traffic signs, or water blast for cleaning road markings. Political pressures also play an important role in road safety. This is true as certain governmental entities may be responsible for the position of entry and exit locations as well as unplanned crossings through medians. In addition, the effectiveness of road safety professionals plays a major role in reducing the number of accidents on the roads. Those professionals need to perform at levels comparable to those of their counterparts from developed countries, despite the deficiencies in training. Finally, road safety gets its importance from cultural and religious values. For example, the Holy Koran states that "He who kills a sole is as if he killed all mankind, and he who saves a sole is as if he saves all mankind". All these problems will be illustrated in a presentation showing the challenges facing developing countries and the efforts put forward to solve it.


Piezoelectric transformers have been used successfully in DC/AC or DC/DC converter. However, the use of piezoelectric transformers presents a major challenges for power electronic design: the capacitive nature of such devices makes their use delicate as the instantaneous power may be much greater than the average effective power. Due to this challenge, conventional drive circuits, especially inductor, become too bulky. This work describes a converter suitable to drive piezoelectric transformer with low inductor. The proposed converter is a DC/AC structure, which is capable of producing a unipolar square voltage. The circuit provides for recovery of the energy stored on the clamped capacitance back to the primary power supply when the transformer is de-energized. In our design, an auxiliary shunt circuits are connected to the input terminal. The proposed structure of both theoretical and experimental validations has demonstrated the effectiveness of the proposed technique for recovery energy.


One day in December 1945, eight fellahin rode out on camel-back from their village in the Nag Hammadi region of Upper Egypt, el-Kasr, and stopped at the base of the Gebel et-Tarif some four kilometers away. The Nag Hammadi manuscripts date from the fourth century and are inscribed in Coptic. The first Western scholar to study the Nag Hammadi manuscripts was a Frenchman, Jean Doresse, and his impression was that they constituted "nothing less than the sacred library of an ancient sect, to all appearances complete." The Nag Hammadi Codices constitute one of the most important manuscript finds of the twentieth century, comparable in importance to the discovery of the Dead Sea Scrolls. Study of these Coptic manuscripts has opened up new vistas for scholarship in the fields of biblical studies, early Christian history, and the general history of religions. Keywords: Christian; Coptic manuscripts; el-Kasr; Gebel et-Tarif; Nag Hammadi; Upper Egypt


Several synthesis methods for fail-safe asynchronous sequential machines have been reported recently. All of these methods solve the race problem by using noncritical race state assignments. This approach generally results in large number of state variables, relatively complicated design, and the limitation of single-input change.


Books from the Eimer Belt Library of Vinciana are usually presented with emphasis upon their relationship to our protagonist and central figure Leonardo da Vinci. It was the research for Leonardo da VincFs sources of learning which brought both volumes, the Plutarch of 1491, and Franchino Gafurio's theoretical works on music, 1508 and 1518, to our shelves. It is a fortunate coincidence that our description of Gafurio's printed editions follows Franz Unterkircher's article in the first issue of Libri which describes the treasure of the Österreichische Nationalbibliothek, the Grolier Manuscript of Gafurio's de Harmonia. We have singled out for special description our copies of Gafurio and Plutarch not only for their quality and beauty äs early Italian illustrated books but because they are linked together by documents of ownership. Franchino Gafurio, chief ecclesiastic musician at the Sforza Court in Milan, acquired our specific copy of Plutarchi vitae on January I3th, 1494. Gafurio noted, next to the colophon, the date and price—5 pounds and 10 soldi. He signed his name on the title page, f olio i b, and during the period of his ownership made many marginal notes especiaily while reading the lives of Pompey and Hannibal. Leonardo read the Lives of Plutarch. Can we assume that he used Gafurio's copy when he noted in Ms. B.y fol. 41 a: "Doloni are a kind bf weapon mentioned by Plutarch in the life of Gracchus . . " or when Ais. B., fol. 50 by he noted the names of military engineers from the life of Demetrius?


Following the current direction in Deep Learning (DL), more recent papers have started to pay attention to the efficiency of DL in breaking cryptographic implementations. Several works focus on techniques to boost the efficiency of existing architectures by data augmentation, regularization, etc. In this work, we investigate using mixup data augmentation [21] in order to improve the efficiency of DL-based SideChannel Attacks (SCAs). We validated the soundness of the mixup on real traces collected from the ChipWhisperer board [14] and from the ASCAD database [1]. The obtained results have proven that using mixup data augmentation decreases the number of measurements needed to reveal the secret key compared to the non-augmented case.


Early attribution research suggests that those who view criminal acts as highly internal, controllable, and stable tend to support more severe and retributive punishment. This study aims to further examine how laypeople's attributions for crime relate to their perceptions of responsibility, emotions, punishment goals, and prison reform attitudes. Participants completed surveys with one of five criminal conviction scenarios. Correlational analyses and a path model provided support for links between internal and controllable attributions, high levels of anger and blame, retributive punishment purposes, and judgments against reform funding. Those with higher prison system knowledge and the politically liberal agreed more that prison system change is necessary. The potential use of these data for prison reform activists is considered.


. This work presents the results of the study of the phosphorus concentrations in the coastal water of the southeast coast of Lake Baikal. We have revealed that in May and September, the concentrations of total phosphorus in the coastal water do not exceed the values typical of mesotrophic water bodies. In July, the concentrations of total phosphorus in the coastal water near the Slyudyanka town as well as the Maksimikha and Enkhaluk settlements increase to the values corresponding to hypertrophic water bodies. eutrophication.


Background. The presence of a genetic factor in the determination of leprosy has long been debated. This study tests whether the HLA‐linked control of susceptibility to leprosy and/or for the types of leprosy could be confirmed.


Under the irradiation of the ultraviolet light, Isoeugenol (I) undergoes dimerization in acetone to give diisoeugenol (II) and dehydrodiisoeugenol (III). The structures are determined by the comparison of the mixed m. p., I. R. spectra and T. L. C. with synthesized authentic samples. Also the photoreaction mechanism is discussed in detail. The reaction represents a new type and as an exception of photochemical process for the C=C double bond in conjugation with aromatic ring that generally dimerizes to produce cyclobutane type derivatives.


In Mexico accidents are one of the four leading causes of death, with an impact on the young and economically active population. The trauma patient, once stabilized his vital functions, must be defi ned, classifi ed and ranked by the orthopedist, conducting primary and secondary assessment, identify and consider the factors involved in the prognosis in order to make a suitable treatment. The orthopedic damage control allows the physician to establish a brief process of treatment to prevent death due to physiological changes associated to trauma. This conduct provides a quick control and support of critical patient, as immediate defi nitive treatment of musculoskeletal injuries can be harmful. Implants and surgical techniques have had to adapt to the increasing number of patients with injuries from high-energy mechanisms and osteoporosis. Implant selection for distal femur fractures secondary to high-energy trauma, depends on fracture type, bone quality, need of angular stable implants, implant acquisition feasibility, surgical techRESUMEN


The thesis discussed the goal and some legal impediments to developing the peasant farm enterprises (PFEs)in Russia.There are three directions of legal reform concerning promoting the development of the PFEs. They are to continue actualizing privatization, to abnegate large farm economy and to consummate the methods of withdrawing land shares from large agricultural enterprises. It brought forward some proposals concerning China's agricultural land property reform. We think that on the basis of new agricultural land property structure in according with China' s national conditions, our country's PFE economy could get the same prodigious development as Russia.

Fine particulates that are emitted from commercial coal combustion sources can be inhaled into human respiratory systems and have been known to cause various harmful effects. Therefore, legislation has been enacted to limit the emission of fine particulate matter in many countries. A fundamental understanding of the mechanisms of fine particle formation is an important step to mitigating the environmental impacts of coal combustion. In this study, 15 pulverized coal samples were burnt in a drop-tube furnace to investigate the formation of fine particulates and the influence of coal ash properties on their emission. Coal combustion was carried out at 1673 K in air. Fine particles were collected by a cyclone and a low-pressure impactor. The elemental compositions of the collected particles were analyzed by scanning electron microscopy with energy-dispersive X-ray spectroscopy. We examined the chemical compositions of the fine particles as a function of particle diameter and examined the proportions of the e...


Focusing on object contour extraction technology that had the most significant impact on the process of image analysis, an efficient method was proposed for object contour extraction based on probability distribution. First the foreground object was detected and its hue feature was used to build an object probability model. With this model, the probability distribution image was calculated on the whole image for the object. Finally, the contour was obtained from the probability distribution image directly. After testing the method using 2330 continuous images containing moving object, the results suggest that the method can work efficiently. It takes 20ms to 30ms to process a true color image of 640×480 pixels, and the contours extracted are very clear and accurate.


Remarkable thermal stability is exhibited by [FeII(tcne)2]⋅x CH2Cl2 (57Fe Mossbauer spectra reveal that the oxidation state of iron is II), which was prepared by treating the MeCN solvate of FeI2 with tetracyanoethylene (TCNE). This method, which can also be applied to synthesize the analogous Mn, Co, and Ni compounds, provides a simple route to novel molecule-based magnets with interesting properties.


In response to a recently reported observation of evidence for two classes of Type Ia Supernovae (SNe Ia) distinguished by their brightness in the rest-frame near ultraviolet (NUV), we search for the phenomenon in publicly available light-curve data. We use the SNANA supernova analysis package to simulate SN Ia-light curves in the Sloan Digital Sky Survey Supernova Search (SDSS) and the Supernova Legacy Survey (SNLS) with a model of two distinct ultraviolet classes of SNe Ia and a conventional model with a single broad distribution of SN-Ia ultraviolet brightnesses. We compare simulated distributions of rest-frame colors with these two models to those observed in 158 SNe Ia in the SDSS and SNLS data. The SNLS sample of 99 SNe Ia is in clearly better agreement with a model with one class of SN Ia light curves and shows no evidence for distinct NUV sub-classes. The SDSS sample of 59 SNe Ia with poorer color resolution does not distinguish between the two models.


The aim of this study was to evaluate the effect of various binders, Type 1 ordinary Portland cement, ternary cement and blast furnace slag, on the concentration of chrome (Cr) ions in leachates. The influence of the presence of another ion, molybdenum (Mo), in solution on the fixation of Cr was also evaluated. The static leaching results show that all stabilizing materials are effective in reducing Cr ions from the solution. Cr ions were almost completely confined in the solid phases, but the Mo ions were not completely stabilized by the ground granulated blast furnace slag. Also, no ionic competition between Mo and Cr ions was observed.


Accurate housing price forecasts play a critical role in balancing supply and demand in the residential real estate market, as well as in achieving the goals of various stakeholders – buyers, investors, construction contractors, public administration, real estate agencies, special investment purpose companies, etc. The present study aims to investigate the relationship between specific predictors and build a suitable model for forecasting housing prices in Bulgaria. In this regard, a study was conducted on transactions with residential real estate in the city of Sofia for the period from the first quarter of 2016 to the fourth quarter of 2021. The ARIMA model is used in the development to predict the values of the variables. Eight models are tested for the researched factors (24 in total). On this basis, the price per square meter of residential property was predicted, including estimated values from the ARIMA model for the parameters involved in the regression equation. The result showed that there is a strong relationship between the analyzed predictors and the studied variable – price per square meter of housing. The tested models are adequate and the statistical requirements for forecasting the prices of residential properties in Bulgaria are complied.


Estimating the cognitive state of an operator has drawn increasing attention in recent years. Cognitive behavior has been effectively studied by analyzing electroencephalogram (EEG) signals. EEG has an excellent temporal resolution but poor spatial resolution; therefore, it cannot be efficiently used for the cognitive state assessment. To obtain the spatial as well as the temporal resolution of the EEG signal, we propose to combine the filter bank common spatial pattern (FBCSP) method and long short-term memory (LSTM)-based deep ensemble model for classifying the cognitive state of a user during the mental arithmetic experiment. The proposed deep ensemble model produces 87.04% classification accuracy, and it achieves an improvement of 2.04% over the state-of-the-art method. In addition, we propose an algorithm that enables us to identify the brain dynamics for each cognitive state, which is equally important to the estimation of the cognitive state in cognitive neuroscience. For each cognitive state, the proposed information flow algorithm constructs a graphical brain network using functional and effective brain connectivity patterns, which indicates the connection strength as well as the causal effects between two anatomically separated brain regions. The proposed information flow algorithm provides an effective way of communication between different brain regions.


Abstract : The U.S. Army Engineer Topographic Laboratories (USAETL) geographic information systems (GIS) research program seeks to define GIS requirements for operational use in the 1990's and beyond, and to develop advanced GIS processing techniques that will facilitate detailed, near-real time update and revision and terrain product generation. USAETL has initiated two new work units in the GIS technology base research program. The projects follow an earlier work unit, the Terrain Analyst Work Station (TAWS), which successfully demonstrated microcomputer-based GIS technology in field and Army garrison environments. From evaluations of TAWS demonstrations and development activities, researchers are proposing baseline Army GIS requirements and are working at developing corresponding performance standards. The functional requirements are and the Soldier-to-GIS Interface Research (S-GIR). AGE is a study to test and anticipated Army requirements for the management and manipulation of digital terrain data (DTD). S-GIR is a developmental effort which will study and prepare a dynamic design for a specialized direct a sophisticated shell or front-end for GIS modules which will be selected (based on AGE study results) for use in a prototype advanced Army GIS.


Potato spindle tuber viriod(PSTVd) could cause serious impact on yield and quality in potato.A pair of primers were designed and synthesized based on PSTVd homologue sequences.Using the total RNA of infected potato tubers from Shanxi Province as a template,full length cDNA fragments was amplified by RT-PCR method.The fragment was cloned into pBS-T vector and sequenced.It showed that cloned PSTVd-SX isolate was 359 nt in size and could produce a self-complementary rod-shaped secondary structure.Blast search showed that PSTV-SX isolate shared 100% identity with PSTVd-H isolate(GenBank accession:AY372400.1).Sequence alignments showed that 12 single nucleotide polymorphisms(SNPs) existed among PSTVd-SX and other five strains,including PSTVd-DB,PSTVd-HB,PSTVd-M(GenBank accession:M14814.1),PSTVd-S(GenBank accession:U23058.1),PSTVd-I(GenBank accession:AY937179.1),five of which existed in pathogenicity region.The viroid-free tomato plants were inoculated with the PSTVd-SX transcripts in vitro and the plasmid pBS-PSTVd linearized with BamHI respectively.PSTVd was detected by RT-PCR in all inoculated plants 20 d later.It showed that the sequences of RT-PCR products shared 100% identity with PSTVd-SX inoculations.


Abstract Solvothermal reactions of AgNO3 with 9,10-anthraquinone-1,5-dicarboxylic acid (H2L) and 4,4'-bipyridine (bipy) gave rise to a metal-organic framework, namely [Ag(L)(bipy)]n (1), which was structurally characterized by elemental analyses, IR spectra, and X-ray diffraction analysis. Single-crystal X-ray diffraction analyses indicate that 1 exhibits a 2D 44 topology framework assembled by dinuclear [Ag2(COO)2] units, L and bipy ligands. 1 displays highly sensitivity in the detection of nitrobenzene (NB) as a fluorescent sensor. Moreover, 1 exhibits a relatively good photocatalytic activity towards the degradation of rhodamine B (RhB) in aqueous solution under UV irradiation.


The inadequacy of the titrametric method for measuring gastric acidity with Topfer reagent as indicator for the study of gastric anacidity in the intact stomach has been emphasized previously. 1 More recently 2 this inadequacy has been shown to be perhaps even greater if the method is used to evaluate the effect of subtotal gastrectomy on the secretion of the remaining gastric pouch. In both of these studies we found the determination of hydrogen ion concentration of the gastric contents to be the most precise method for establishing the true status of gastric acidity when no titratable free acid is present. It is vital for the ulcer patient who has had a subtotal gastric resection to develop an anacidity in the remaining gastric pouch if he is to be safeguarded against the development of new ulcers. We believe that it is important to study gastric secretion in these patients very


In this study, we conducted an assessment of the risks posed by the noxious chemicals often handled at the analysis centers of organizations involved in Work Environment Measurement (WEM) using the Chemical Hazard Risk Management (CHARM) system. For this purpose, six organizations involved in WEM located in Seoul and Gyeonggi, which conducted the risk assessment, were selected and, as a result, 29 materials were selected as chemical substances presenting a risk of exposure. In terms of their physical properties, there were 16 liquid and 10 solid materials, and for the special management materials (CMR), the findings were as follows: 'Carcinogenic' 1A 11 and 1B 1 (2 8); 'Mutagenic' 1A 4 and 1B 3 (2 8); and 'Repro-toxic' 1A 0 and 1B 1 (2 6). In the risk estimation, 30.4%, 66.1% and 3.6% of the materials presented 'low', 'average' and 'high' risks, respectively. In addition, two of these six institutions had materials presenting a 'high' risk. This study is significant in that the risk assessment was conducted using CHARM, a chemical substance assessment tool. It is expected that the results will be utilized as the basic data for safety assessment, the establishment of a plan for emergency measures and drawing up a safety management manual, and the institutional and legal management of accidents and risks in the analysis centers of organizations involved in WEM and the management of chemicals by drawing attention to the risks involved.

This study explores the effects of origin-destination (O-D) attributes on route choice with long-term GPS data collected by private vehicles in Toyota city, Japan. The non-linear fixed effects are captured by the piecewise specified structural tastes on costs in the utility functions. The multi-level random effects are captured by the multi-level random terms. This empirical analysis demonstrates that the incorporation of O-D attributes can enhance the route choice models significantly. The effects of both O-D distance and drivers' familiarity with the O-D on route utilities are proved to be non-linear and non-monotonic. Besides the fixed effects, the multi-level random effects of OD attributes are also confirmed to be significant.


Dalit women in Indian society are triply exploited on the basis of caste, class and gender. In this context after defining the term Dalits sociologically this paper attempts to establish that Dalit women are different from general caste women on the basis of their structural location, occupations they perform and treatment meted out to them by society in general. The paper captures the existing prejudice and contempt against Dalit women which in a way gets articulated by the atrocities committed on them by the so-called upper castes. The paper explores how Mayawati has become an icon of the Dalit society by deconstructing many established images of Dalit and general caste women. We have tried to understand why the Indian media has failed to appreciate her achievements in full glory. Last but not the least why has the Indian women's movement not accepted Mayawati as part of it and defend her from onslaughts of media and prejudices of caste in the male-dominated society?


Midline fracture is the most common fracture seen in the patient with conventional acrylic resin maxillary denture against the opposing complete or partial natural dentition. This happens due to excessive masticatory forces from the natural dentition against the opposing arch. To overcome this problem, stainless steel can be added either in the form of mesh, bar or plate. In this present case report described the prosthetic rehabilitation of a complete maxillary edentulous and partial mandibular edentulous patient with stainless steel mesh reinforced maxillary removable complete denture and conventional removable partial denture to improve the impact strength of the denture and also at the same time to reduce the chances of alveolar ridge resorption.


Costs of wateIfront unreliability to ship-owners were estimated from information provided by operators of liner ships and by bulk shippers. These costs totalled $200 $250 million in 1988 Costs to imports and exports were estimated from data derived from a survey.. Total costs of waterfront unreliability to national welfare were estimated to have been in the range $900 $1020 million in 1988.. Some of this reflects the costs of delays originating outside the waterfront.. It is improbable that these costs could be reduced to zero, and no attempt is made to estimate to what amount they could be reduced or the costs of reducing them Bureau of Transport and Communications Economics GPO Box 501 Canberra ACT 2601 Telephone (06) 274 6827 Fax (06) 274 6816

Abstract
Nowadays, there are many strategies to learn English as the second language especially for the young language learners. The main part of learning a language is the language skill. In learning English, the students will learn four language skills, namely: listening, speaking, reading, and writing. In term of speaking, most of the students got difficulty in following the speaking class. Teaching speaking for young language learners is an interesting and challenging duty for teachers for some considerations. However, the teachers have tried many ways to teach the students to be able to speak in English, but the fact is there are still many students could not do it well though speaking is the main purpose in learning other language instead of the mother tongue. The problem that the writer intends to discuss in this paper is concerned with the speaking ability of the second year students of SMK Darel Hikmah Pekanbaru by using simulation method in the learning process. The reason for choosing the method because, it could help the teachers to create a very good way in teaching English. The teacher should utilize a teaching method that is attracting to teach speaking for the students which includes materials, comfortable environment, self-confidence teachers, etc. In other words, the better the teachers in using this strategy, the more interest the students in speaking subject. The objective of this research is to explain the method of simulation in improving the speaking ability of the second year students of SMK Darel Hikmah Pekanbaru.


Distal extrahepatic bile duct (EHBD) cancer is highly recurrent. More than 50% of patients suffer from disease relapse after curative resection. Some patients present with oligo‐recurrence which could be a single loco‐regional mass or lesions limited to a single solid organ. The aim of this study was to examine the effect of local control (surgical resection or radiofrequency ablation) on survival outcomes in patients with oligo‐recurrent distal EHBD cancer.


The inclusion of information and communication technologies in education has become a priority for all universities. To meet this need, there are several research works that have dealt with the subject for several decades. However, for its inclusion, the analysis of each institution is necessary since the needs of the university population and the resources for its application change according to each situation. This work seeks to create a method that allows establishing the needs and doubts of students about the use of educational technologies in the classroom without affecting their performance. For this, a process has been designed that identifies learning needs, through the validation of data obtained from surveys and the monitoring of the academic efficiency and learning of a cohort of students. The follow-up includes a period of four years from 2019 to 2022. This follow-up allowed establishing three different realities, in 2019 the academic data was analyzed in a face-to-face education model, from 2020 to 2021 the follow-up was included in a remote model with the use of technologies as a communication channel and in 2022 these were included as a learning component, which marked an in-depth analysis of student performance and how technology affected their learning.


The iconic white coat was originally worn by physicians in the laboratory setting in the 19th century. At the time, advances in medicine meant that people were actually starting to survive their stays in hospital. Hospitals had been associated with almost certain death before this point. The white coat gradually became adopted worldwide, its colour being associated strongly with authority and healing. It is still popular throughout the world today. Many medical schools in the USA hold a formal robing ceremony.


The present work was conducted to investigate the chemical composition (amino acid, mineral content, and lipid profile) of bones from three different Iranian pelagic fish species. The biochemical composition of Sardinella gibbosa, Clupeonella engrauliformis and Stolephorus indicus bones captured from the Iranian Ocean (the Oman Sea and Caspian Sea) were determined. The analysis of amino acids and fatty acid profiles was done by HPLC and GC and also analysis of minerals was done by means of flame atomic emission spectrophotometry. The least amount of mono unsaturated fatty acids was observed in C. engrauliformis (p<0.05). The highest contents of polyunsaturated fatty acids and n3/n6 ratio were observed in bones of C. engrauliformis. High levels of Ca, Fe, P, Zn and Cu minerals were measured in S. gibbosa and C. engrauliformis, respectively. The highest values of basic amino acid and sulfur containing amino acids were measured in S. gibbosa and C. engrauliformis, respectively. The chemical index did not reveal lack of any essential amino acids in three studied fish varieties compared to reference protein. On the basis of result, the best bone composition was observed in S. gibbosa. Therefore, the use of bone powders varieties of these fish could be useful in food industries.

Deep learning has a promising impact on target classification performance at the expense of huge training data requirements. Therefore, the use of simulated data is inevitable for convergence of deep models (DMs). However, generating synthetic data for real-life complex targets can be quite tedious and is not always possible. In this study, DMs trained with synthetic one-dimensional scattered data of elementary targets are transferred to classify complex targets from measured signals for the first time. For this purpose, a novel system is proposed by combining three strategies: first, initial training of DMs using analytical and simulated time domain scattered data obtained from the basic targets; second, the last layers of initial DMs are fine-tuned by transfer learning using measured signals of the real targets; and third, an ensemble model is developed to generate a model that can completely represent real target characteristics by combining diverse and complementary properties of the fine-tuned DMs. The proposed system provides higher accuracy, sensitivity, and specificity performances compared to the existing methods.


The impact of quantum fluctuations on the phase diffusion in resistively shunted superconducting quantum points subject to an external ac-voltage is studied. Based on an extension of the classical Smoluchowski equation to the quantum regime, numerical results for fractional and integer Shapiro resonances are investigated to reveal characteristic features of quantum effects. It is shown that typically in the quantum regime the broadening of resonances cannot be described simply by an effective temperature.


Air-traffic control is a complex and high-stress business. Mistakes are not allowed. And it's not limited to directing planes for takeoff and landing - a job that's been memorably described as three-dimensional chess. It also includes keeping track of where planes are on the ground. According to safety watchdog Eurocontrol, in 2005 alone there were 600 occasions when people, cars, or planes crossed Europe's airport taxiways when they shouldn't have. In fact, the most deadly airline accident ever happened on the ground: in 1977, two 747 jumbo jets collided in the Canary Islands, killing 583 people. Most big airports have expensive ground-radar systems to keep track of where the hundreds of moving planes are on the sprawling tarmacs. But ground radar sometimes reflects off buildings and terminals, leaving small gaps in coverage. Smaller airports like the one in Thessaloniki, Greece, can't afford ground radar. Such blind spots on the ground at airports large and small have prompted European researchers to explore the use of fluctuations in the Earth's magnetic field to better pinpoint where planes are on busy taxiways. The results, researchers say, show that using US $150 sensors can fill in the blind spots.


Abstract In buffalo industry artificial insemination is being used in breeding programs of our country . It has limitations such us seasonality, difficult estrus detection and low pregnancy rates when compared with cattle. IATF programs using a single insemination show results from 10 to 50% pregnancy rate, little information is available about minimum requirements of spermatozoa for IA. The aim of this paper is to compare the pregnancy rates after using narual mating or frozen semen in a sincronization of ovulation program. This work were conducted in Pueblo Nuevo Cordoba Colombia in August during the breeding season of 2005-6. 99 multiparous crossbred females were used with 50 to 150 postpartum days. Body score condition of 3,5 to 4. All animals were palpated to exclude anatomical alterations. Ovsynch protocol for IATF reported by Baruselli (2000), they were allocated in two groups: Buffalo group, after the last GnRH analog injection 17 females were allocated with 5 bulls, and IATF Group 82 females were inseminated 16 hours later. The semen of 7 different buffalo bulls were used and evaluated and qualified as normal. Inseminations were performed by 3 different technicians. A blood sample was obtained 20 days after IA to determine pregnancy by determinations of P4 levels using chemiluminiscence, ≥1ng/ml were used as cut off value to determine pregnancy. Data were compared using Chi square test. 70% (12/17) females of the bull group and 29% (24/82) of IATF group were diagnosed us pregnant using P4, this difference were statistically significant (P≤0.001). Buffalo bulls mount all females. No statistical differences were found in pregnancy rates of the bulls used for IATF, from 12% to 37 %, one exceptional bull obtain 71%. As expected bulls have higher pregnancy rates than artificial insemination, the results obtained here allow researchers to evaluated semen quality, specially density to improve results IATF in buffaloes.


Noise reduction is a basic problem in image processing, binary image contains less information than color images, which means it's more difficult to reduce noise in binary image. The most used noise reduction methods are mathematic morphology and median filter, but they face a common problem that the fine structure information in the image was destroyed in the process of noise reduction. Inspired by the quantum theory, we express an image with quantum system first, after that, a new distance measurement between quantum states was proposed, then we advance a concept, noise feature codebook, to describe the local feature of each pixels in the image. The distribution of the codebook in images with difference noise density was studied, the relationship of the distribution and the noise density was built up by training of masses of images. With the regularity, a noise reduction method was proposed, which choose optimal noise judging criterion according to noise density of the image. Experiment showed that proposed method gain higher SNR and better visual quality than tradition noise reduction methods in most situation.


131I is a very important nuclide applied in nuclear medicine.133Ba,an EC decay nuclide,plays a significant role in the efficiency calibration of HPGe detector.The activity measurement method for the above two kinds of nuclides was studied by the 4πβ(PPC)-γ(HPGe) anti-coincidence counting.The specific activity measurement result for 131I sample is 1 794.8(1±0.6%)kBq·g-1(k=1)and for 133Ba is 502.8(1±0.6%)kBq·g-1(k=1).Compared with the results measured by 4πβ(PC)-γ(NaI(Tl)) coincidence efficiency extrapolation methods at the same reference time,1797.6(1±0.5%)kBq·g-1(k=1)and 504.9(1±0.6%)kBq·g-1(k=1),it is in good agreement within the uncertainties.


Recently, the increase in energy consumption of commercial building is remarkable, and energy-saving is continuously required. Therefore, the government is promoting high environmental performance building. In this situation DECC (Database for Energy Consumption of Commercial building) committee collected the data of the energy consumption and published them as a database. However, analysis about High environmental Performance Building (HPB) has not been conducted in DECC database. So, I extract HPB from DECC database and analyze the consumption.


I first review positive-operator and projection valued measures in quantum mechanics, and then address a few applications in quantum key distribution (QKD). The positive operator valued measure (POVM) is useful in the design of a quantum key receiver. The projection valued (PV) measure is useful in the design of QKD eavesdropping devices. In this case the measurement determines correlations with the measurements made by the lefitimate receiver and therewith the maximum information gain by the probe. It is essential to know the latter for privacy amplification.


We present a new iterative method for designing Bragg gratings based on the Levenberg-Marquardt method of minimizing a chi-squared merit function. It is effective and suitable for designing both weak and strong unchirped gratings.


In this communication the author gives an account of an investigation with which he has been recently occupied, into the process of inflammation in the Frog's foot. The paper is divided into four sections, with an introduction and conclusion. In the introduction it is observed, that "so far from our knowledge of inflammation being in a satisfactory condition, authorities are at variance upon the fundamental question whether it is to be regarded, in accordance with John Hunter's opinion, as active in its nature, and consisting in an exaltation of the functions of the affected part, or whether it should not rather be considered a passive result of diminished functional activity.......In seeking for the solution of this great problem, we cannot expect to gain much from the contemplation of the more advanced stages of inflammation.......It is upon the first deviations from health that the essential character of the morbid state will be most unequivocally stamped, and it is therefore to the early stages of inflammation that our attention must be chiefly directed."


Incorporation of fly ash in cementitious systems containing ordinary portland cement (OPC) increases their long-term strength and durability. However, replacement of cement by fly ash also reduces the heat of hydration of such systems and reduces early-age strength development. The reduced rate of strength development can increase the risk of durability problems, e.g. scaling, in cases when young concrete is exposed to low temperatures and deicing chemicals. This study investigated the potential of nano-titanium dioxide (nano-TiO 2 ) particles to modify the hydration kinetics of fly ash pastes and compressive strength development of corresponding mortars cured under low (4°C) and standard (23°C) temperatures. The kinetics of the hydration study was performed on paste specimens using the thermogravimetric analysis (TGA) and isothermal calorimetry (IC) methods. The mortar specimens used for compressive strength testing were prepared using the same w/cm values and the same types of binders as those used to prepare the paste specimens. It was found that although the addition of nano-TiO 2 accelerated the hydration rate of all pastes, that treatment was, however, more effective in the fly ash pastes than in the ordinary portland cement (OPC) pastes, especially for the cases of low temperature curing. These findings were confirmed by the results of strength testing as the specimens experiencing accelerated rates of hydration were also found to be stronger.


Effect of dopamine agonist Parlodel in treatment of different types of depressions was investigated. Parlodel was found to have an antidepressant action which enabled to cure some resistant forms of the disease. The positive therapeutic effect of Parlodel resulted in normalization of dopamine metabolism. The drug can be used for treatment of depressions accompanied by dopamine deficiency and resistant to therapy.


Effects of irrigation techniques on N distribution of diffferent N-fertilizers in soil and tomato plants were studied by micro-plot planting experiment in grennhouse. The results showed that inorganic N mainly existed in the form of NO3--N, while NH4+-N only occupied small amount during the whole growing period. Whatever drip irrigation or furrow irrigation, in 0~100cm soil layer, the NH4+-N content was stable at a lower lever of less than 6mg kg-1, and was slight affected by different irrigation and fertilization; in 0~20cm soil layer, NO3--N content maintained much higher. The NO3--N content could move to lower soil layers in furrow irrigation, while drip irrigation will not influence distribution of NO3--N in or below 40-60cm soil layer. For NO3--N fertilizer, it's more easier to move to the deep soil layer with the irrigation water than NH4+-N fertilizer and NH2-N fertilizer. No significant effects of irrigation techniques on the distribution ratios of 15N among the fruits, stems and leaves had been observed. Among the above-ground parts, fruit contained the highest 15N, then followed the leaves. The stem contained the minimum 15N. In terms of 15N distribution ratio, there is no difference among the fruit, stem and leave in both irrigation techniques with average ratio of 2.9∶1∶1.6.


university economics; higher education management; university strategy; university competitiveness; entrepreneurial universities; extrabudgetary revenues; scientometrics This study is aimed to study the mechanisms that contribute to increasing the economic independence of universities, which in conditions of high dependence on-budget funding is exceptionally relevant in Russia. Even though the share of extra-budgetary revenues is growing at most Russian universities, this growth is heterogeneous and partly due to the "low base effect".


The main signaling pathway involved in migration, adhesion and homing of hematopoietic progenitor cells (HPC) is the CXCL-12, chemokine produced by bone marrow (BM) stromal cells that bind to its main receptor CXCR-4, expressed by HPC. ARHGAP21 is a RhoGAP member, negative regulators of RhoGTPAses. It was described that ARHGAP21 is involved in cellular migration and adhesion but its role in hematopoiesis is unknown.

Researching Arhgap21 role in hematopoiesis, Arhgap21+/- mice were generated using Embryonic Stem cell obtained from GeneTrap consortium. Hematologic parameters were investigated by blood cell count, colony formation assay in methylcellulose medium and immunophenotipic characterization of hematopoietic populations. Transwell migration and adhesion of Lin- cells assay in the presence of CXCL12 were also performed.

In vivo analysis of Arhgap21+/- HPC was achieved with homing and CFU-S assays in sublethally irradiated mice and hematopoiesis stress was generated by 5-fluoracil treatment.

Arhgap21+/- mice presented more than 50% reduction in Arhgap21 expression (0.47 ± 0.13) in BM when compared to WT (1 ± 0.03) and live in normal conditions. On the other hand, Arhgap21 mice showed a reduction in BFU-E colonies and erythroid (Terr119+) committed cells in BM together with decreased peripheral blood (PB) Terr119+ cells and red blood cell number and increased medium corpuscular volume.

In myeloid compartment, Arhgap21+/- mice presented less GM colonies and myeloid (Gr1/Mac1+) cells in BM followed by an increase of these cells in PB suggesting myeloid mobilization. Corroborating to this, when Arhgap21+/- BM was challenged for hematopoiesis stress with 5FU, the animals showed increased neutrophil number in peripheral blood 14 days (WT: 1887/mm3 ±721.9; Arhgap21+/- :3325/mm3 ±1640, p=0.02 ) and 21days (WT: 1264/mm3 ±635; Arhgap21+/- : 2182/mm3 ±854, p=0.01 ) after treatment, together with increased number of LSK cells in the BM (WT: 1.3% ±0.4; Arhgap21+/- : 1.9% ±0.3, p=0.006 ) 28 days after 5FU infusion.

Erythroid and myeloid compartments reductions were observed together with an increase of Arhgap21+/- BM short term LSK( Arhgap21+/- : 0.34% ±0.13; WT: 0.18% ±0.07, p=0.03 ) and long term LSK ( Arhgap21+/- : 0.003% ±0.001; WT: 0.002 ±0.0007, p=0.02 ) suggesting an attempt to restore normal hematopoietic levels.

Arhgap21+/- HPC showed reduced CXCL-12-induced migration compared to WT (WT: 100%, Arhgap21 +/-: 54.73% ± 13.57, p=0.01 ) in addition to decreased adhesion to fibronectin (Arhgap21+/-: 15% ± 3.8; WT: 27% ± 3.5, p=0.003 ) and a4b1 integrin expression (WT: 83.76 ± 4.35; Arhgap21 +/-: 71.06 ± 7.00, p=0.008 ).

In homing assay, the percentage of donor Lin- HPC from Arhgap21+/- mice that homed to BM (6.32 ± 2.41) or spleen (3.48 ± 1.57), were lower than those from WT mice (BM=10.09 ± 1.81; p=0.004; spleen= 6.9 ± 1.48; p=0.0007 ) together with higher frequency of these cells in peripheral blood (WT: 6.39 ± 3.38; Arhgap21 +/-: 13.95 ± 5.33, p=0.003 ), suggesting a retention of Arhgap21 +/- HPC in the bloodstream, which inefficiently home to BM and spleen. Arhgap21 +/- CFU-S capacity decline was also observed ( Arhgap21 +/-: 20.86 ± 2; WT: 29.29 ± 5.4 p=0.002 ).

This is the first study showing that ARHGAP21 is involved in hematopoiesis and also shows that ARHGAP21 is an important protein for chemotaxis, adhesion, homing and short term reconstitution of HPC.

fields of law, economics and political science. The book contains 22 individual contributions that are divided into six parts that deal with a wide range of different aspects of modern trade policy. The first part 'Trade as an "Engine" of integration, growth or inequality?' has three chapters and deals with the relationship of trade with communication, economic growth and social inequality. Part II, entitled 'Domestic politics, development strategy and democracy', comprises five chapters which explore the interdependency of these issues. Regionalism, specifically in Asia, Africa and Europe, is the focus of Part III 'Regions and regionalisms in the lead' that contains five chapters. In Part IV entitled 'The global governance of trade: who's accountable and who governs?', the multilateral trading system gains centre stage within three chapters. In Part V, 'Trade as globalization', and Part VI, 'The future of trade', that contain four and two chapters, respectively, the authors focus on various aspects of globalisation and its impact on trade and other economic and social issues. The volume has in my view two main strengths. First, the editor has gathered authors from different countries and academic disciplines which guarantees an interdisciplinary perspective on the international political economy of trade. The book therefore not only covers the theoretical underpinnings of trade and the domestic political dynamics of trade policymaking in different contexts but also the global governance of trade and the international trend towards bilateral and regional trade agreements. Second, the volume makes clear that trade policy of the twenty-first century is not simply about tariffs but touches upon a wide range of issues such as migration, food, the environment, social standards and even the internet. Against this background, the only shortfall of this volume seems to be its misleading title. Rather than a handbook, it is a loose collection of cutting-edge research on trade policy. Students who are looking for a structured introduction to trade and trade policy will be disappointed, since each article studies in depth very specific research questions and often requires substantial background knowledge of international trade policy. The book therefore seems to be better suited for scholars of trade policy and practitioners in civil society, government agencies and international bodies.


A simple, rapid, accurate method for the determination of total cholesterol in foods has been devised.The method involves saponification of the food with alcoholic KOH, extraction of the free cholesterol with petroleum ether and measurement of the cholesterol by means of the Liebermann-Burchard color reaction.The following experiments have been carried out for the investigation of the proposed method.1.In the recovery test with cholesteryl-palmitate, the reproducibility was 99.3%.2. In the addition test with fish samples, 100±3% of cholesterol was recovered.3. The proposed method was compared with Schoenheimer-Sperry method for fish samples, and slightly higher values were obtained by the former.4. The influences of fat soluble vitamins on the method were studied, and the result showed that there was no influence by fat soluble vitamins on Liebermann -Burchard reaction in the ordinary or common foods.


Abstract Sustainable agricultural practices, such as conservation agriculture (CA), remain an important crux of conservation efforts to boost food crop production output due to productivity decline. Using cross-sectional survey data from 350 smallholder farmers, this study investigated the likelihood of adoption of CA practices in South-West Nigeria based on a number of factors as well as factors predicted to effect farmers' output when these practices were adopted. Cross-tabulation technique was applied to profile the farmers' features, while heckman selectivity model was used to estimate the effect of CA adoption on farmers' production output from CA plots and to sequentially address potential selectivity problem in a bid to disentangle the effect of adoption and other confounders which vary across individual farmers. Findings revealed that exposure time period, land acquisition, CA farm size cultivated, total farm size, access to extension services and social capital components are significant predictors of adoption. Likewise, human capital (years of formal education and farming experience), marital status, access to extension service and frequency of extension visit significantly predict farmers' production output. Most importantly, the estimated selection bias control parameter was significantly different from zero, which is an indication that there was a significant effect of CA adoption on farmers' production output from CA plot.

Nb-C nanocomposite thin films with carbon content ranging from 0 to ~100 at.% were deposited at room temperature by non reactive magnetron sputtering from pure Nb and C targets without applying bias voltage or additional temperature to the substrates. XPS analysis showed the co-existence of NbC and free C-C phases with different proportions while complementary Raman analysis showed that the carbon changes from graphite like to amorphous like as the Nb content of the films increased. XRD analyses showed the evolution of the crystalline structure of the samples from amorphous/nanostructured to cubic NbC with a relatively high crystallinity. HRTEM images confirmed the nanocomposite structure with NbC nanocrystals of different sizes embedded in the carbon matrix. The nanohardness of the films showed a strong dependence on the amount of the carbon matrix, with a maximum hardness of 23 GPa for the film with ~8-10% percent of the free carbon. The same film showed a four-point probe electrical conductivity of 2.2x106 S/m at 22C. The fact that the substrates do not need to be heated to obtain relatively hard, elastic and electrically conductive nanocomposite structures opens the possibility for a wide range of applications for temperature sensitive flexible substrates such as polymers and plastics.


An experiment was conducted under polyhouse and field conditions during 2013, 2014 and 2015 to evaluate the level of resistance of less known apple rootstock, i.e. Paron (Malus baccata var. himalaica) and some popular rootstocks of the region (MM 106, MM 111, M 9 and Srinagar crab) against white root rot disease. All the test rootstocks were grafted with CITH Lodh Apple-1 before their use in field conditions. Paron showed high resistance against D. necatrix by exhibiting least mortality (15.33%) at highest test dose (10 g/kg soil) of inoculum in pot culture under polyhouse, whereas other test rootstocks showed 100 percent mortality at this dose of inoculum. In the field, Paron showed no wilting symptoms on scion cultivar even after 60 days of inoculation, it showed least bronzing and inward cupping of leaves (3.25%), defoliation (3.50%), necrosis on bark (21 mm), wood (17 mm) and vascular tissues (23 mm). It was rated as resistant against D. necatrix as compared to other test rootstocks on the basis of significantly lowest disease severity (4.35%) and least effect of test pathogen inoculation on its above and below ground parts. Srinagar crab was rated as highly susceptible in comparison as, it exhibited significantly highest disease severity (69.80%). From this study, it can be inferred that the rootstock of Paron should be used for shaping production of apple in Kumaon region of Uttarakhand.

In this paper the author investigates the axisymmetric vibrations of a thin drum which consists of a circular cylindrical shell and two circular end plates. He obtains the Lagrangian of a drum from the ones of a cylindrical shell and two plates using the conditions of continuity and then gets the frequency equations and the displacements minimizing the Lagrangian. If the length is sufficiently large in comparison with the radius, the vibrations of drum are much the same as the ones of cylindrical shell free at both ends. So we can say that the influence of the end plates is negligible in such a case. But the decrease of its length causes the increase of its frequency and the vibrations of its plate to shift to the higher mode patterns successively, while the ones of its cylindrical shell shift to the lower ones correspondingly. If the radius is very large in comparison with the length, the vibrations become nearly the same as the ones of the circular plate clamped or free on the edge circle.


The temperature dependence of threshold current of strained quantum well lasers is analyzed both experimentally and theoretically. The measurements are performed on ridge waveguide In0.2Ga0.8As/GaAs multiquantum well lasers emitting near 1 μm. The carrier densities at threshold of these lasers are measured using very short current pulse injection. A simplified calculation of the radiative, nonradiative recombination rates and the relationship between gain and carrier density in strained quantum well lasers is described. The results of the calculation are compared with experimental results.

Geomagnetic storms are disturbances of the terrestrial magnetic field of several hours with a global character. The origin of this disturbance is the arrival of solar wind disturbed by a coronal mass ejection in which the interplanetary magnetic field has a southward Z component. A geomagnetic storm may result in an ionospheric storm which is mainly characterized by a disturbance of the electron density of the F2-layer of the ionosphere. These ionospheric storms have a major influence on GNSS observables and thus can affect the accuracy in positioning. This work describes the phenomena associated to the geomagnetic storm of 23 of April 2012. The origin was a coronal mass ejection produced the 19th that increased the velocity of the solar wind and changed the interplanetary magnetic field. The arrival of the disturbed solar wind to the Earth triggered a geomagnetic storm that began on 23th and lasted until the 27th. This geomagnetic storm caused an ionospheric storm over Mediterranean region which had several phases whose characteristics depend on latitude, longitude and the stage of the geomagnetic storm in which takes place.


Aim To investigate the effect of LDL (low density lipoprotein) apheresis on ocular microcirculation in patients with hypercholesterolemia Methods Six patients with hypercholesterolemia were included in this study. The diameter of retinal vessels was measured continuously with the retinal vessel analyzer (RVA) before and after LDL apheresis. After baseline assessment a monochromatic luminance flicker was applied to evoke retinal vasodilation. Flicker response was then analyzed 50, 70 and 120 sec after baseline measurement. Additionally, cholesterol, HDL, LDL-and triglyceride level were obtained to find a possible correlation between retinal vessel diameter changes and lipid metabolism before and after apheresis

In the current work, the structural, morphological and optical properties of the Bi2O3/ZnS heterojunctions as visible light communication (VLC) technology element are explored. Bismuth oxide layers of thicknesses of 200 nm are used as substrate to evaporate ZnS films of thicknesses of 500 nm by the thermal evaporation technique under vacuum pressure of 10−5 mbar. The heterojunction devices are studied by the x-ray diffraction, scanning electron microscopy, optical spectrophotometry and microwave spectroscopy techniques. The Bi2O3/ZnS heterojunctions are found to form a highly strained structure with extremely large lattice mismatches. By the strained structure and with the valence and conduction band offsets that exhibit values of 1.04 and 0.41 eV, respectively, it was possible to enhance the light absorbability of ZnS by 459 times at 3.10 eV. In addition, the dielectric constant spectra of the device display a linear and nonlinear optical properties below and above 1.94 eV, respectively. Moreover, the optical conductivity parameters including the drift mobility and plasmon frequency and the cutoff frequency spectra of an area of 0.50 cm2 of Bi2O3/ZnS interfaces have shown the ability of using these heterojunction devices as light signal receivers that attenuate signals at terahertz frequencies in the range of 0.27–1.00 THz. As an additional demonstration, the Bi2O3/ZnS heterojunction devices were subjected to a microwave signal propagation in the frequency domain of 0.01–2.90 GHz. The device performed as band filters at gigahertz frequencies.


ABSTRACT The robustness of the linear combination method to neutron source is demonstrated in the pulsed neutron source (PNS) experiment. The linear combination method reduces the spatial higher-mode (HM) components in neutron flux distribution by integrating the neutron counts obtained in the PNS experiment with the linear combination. In the previous study, we have confirmed the applicability of the linear combination method based on the PNS method conducted at Kyoto University Critical Assembly (KUCA) with a deuteron-tritium (D-T) neutron source. In this study, the PNS experiment is conducted at KUCA with 100 MeV proton accelerator and Pb-Bi target. The experiment is aimed at showing that the masking time dependence of the estimated prompt neutron decay constant is dramatically reduced by the linear combination method compared to the conventional method: these results demonstrate the linear combination method is applicable to spallation neutron source as well as D-T neutron source.


We present a fast, accurate hybrid vortex method for computing incompressible, viscous flow at large Reynolds numbers in a two-dimensional bounded domain. The random vortex method is used to model the flow away from the boundary and the vortex sheet method is used to model the flow near boundary. Our implementation of these methods exploits the localized nature of interactions among vortex elements in each of the respective regions of the domain. A local corrections approximation is used to accelerate the velocity computation in the interior. It is substantially faster than other methods of comparable accuracy and can economically handle tens of thousands of vortex elements. We evaluate the method on the flow in a box due to a central stationary vortex. The running time for this problem is rougly linear in the number of vortex elements and results are in good qualitative agreement with other numerical solutions of the same problem.


The Maca Indians living at Fray Bartolome de las Casas show a high rate of endogamy, high mortality (36% of them die before the age of reproduction), low fertility (average of 3.6 livebirths per female who completed her reproductive performance) and low variance in family size. The index of opportunity for selection (0.88) is lower than the one obtained in other populations of agriculturalists and in industrialized communities. The frequency of H secretors (N = 143) is 97% and that of Lea secretors (N = 123) is 78%.


To achieve the objectives of the Internal Quality Assurance System, the Quality Standard document must be socialized to each work unit, and the existence of information technology will greatly assist in the distribution and socialization of these documents. This study aims to design and build a data model for storage and management of SPMI documents, especially Standard documents, which are generally in the form of files in print or digital format with a complete structure as a collection of text. With the data model designed, the Standard document is stored in a divided state into a number of entities that represent sub-sections of the document and are structured. This research produces a data model design with a relational system, so that it will produce optimal performance when create, retrieve, update and delete operations are carried out on Standard Documents, and still produce complete information about standard documents, as well as one aspect or context. in Standard documents and their linkages, through application programs and information systems. Testing was carried out by the black-box method of the SPMI document information system prototype which indicated that the data model was successfully implemented and worked well in its application.


Machine learning development creates new challenges that are not present in a traditional software development lifecycle. These include keeping track of the myriad inputs to an ML application (e.g., data versions, code and hyperparameters), reproducing results, and production deployment. Existing systems built to address these challenges restrict the supported programming languages and ML libraries that developers can use to train and deploy models, creating difficulties for organizations that must leverage a variety of ML libraries and model deployment environments. Accordingly, we propose to demonstrate MLflow: a system that streamlines the machine learning lifecycle and is designed to work with any ML library, algorithm, or programming language. Available at mlflow.org, MLflow is an open source project with over 70 contributors. Through our demonstration, audience members will interact with each of MLflow's major components, experiencing firsthand how the platform's open interface enables developers across an organization or research group to collaborate on reproducible machine learning workflows that leverage their preferred languages and ML libraries.

We present a multistage stochastic programming model for mean-risk optimization of electricity portfolios containing physical components and energy derivative products. Stochasticity enters the model via the uncertain (time-dependent) prices and electricity demand. The objective is to maximize the expected overall revenue and, simultaneously, to minimize a multiperiod risk measure, i.e., a risk measure that takes into account the intermediate time cash values. We compare the effect of different multiperiod risk measures taken from the class of polyhedral risk measures which was suggested in our earlier work. Furthermore, we discuss how such a mean-risk optimization problem can be solved by dual decomposition techniques (Lagrangian relaxation).
