The two greatest challenges facing dryland ecosystems are: 1) recent and rapid changes in land use and 2) the predicted e↵ects due to climate change, which have potentially devastating consequences on the 2.5 billion people living in drylands around the world. The situation is particularly sensitive in sub-Saharan Africa, where 800 million people are reliant on local crop and animal agricultural food production. The following dissertation will address three main objectives: 1) providing research that focuses on agricultural systems where a direct coupling exists between the natural distribution of vegetation and livestock instead of crop based agricultural systems, 2) advancing the theoretical understanding of the organization of dryland vegetation patterns by developing novel ecohydrologic models, 3) advancing geophysical methods towards providing hydrological datasets at novel spatial and temporal scales in drylands. In Chapters 2 and 5, two novel ecohydrologic models are developed that utilize the resource tradeo↵ hypothesis on the organization of dryland vegetation patterns. Chapter 2 presents changes in the regional distribution of woody species in central Kenya varying rainfall patterns. Model results of future rainfall scenarios indicate expansion of the most drought tolerant species and reduction of the species with the highest water use. Chapter 5 presents results from a spatially explicit ecohydrological model used to understand the spatial patterns of vegetation on hillslopes. The model results suggest a switch in optimal vegetation patterns, from highly organized vegetation clusters to a random distribution of vegetation, by varying two model parameters that control the length scales of plant water facilitation and competition. Chapters 3 and 4 each present novel soil moisture datasets collected with di↵erent geophysical methods. In Chapter 3, direct-current resistivity is used to collect high-temporal resolution soil moisture measurements in a tank laboratory setting. The dataset sup-


We discuss the properties of triangles whose sides establish a geometric sequence, paying special attention to their connections with the golden ratio and issues related to the Fibonacci numbers. We also pose a number of questions concerning the unions of triangles of the considered type.


Clinical History Pie. J W., aged 33, was injured when handling a small mine which exploded. He was admitted immediately to a near-by hospital. There were abrasions and shallow lacerations, some 3/4 by 3 cm. in extent, on the left 'temple, 2 cm. from the eye; a small punctured wound just below the angle of the jaw on the left; and several minor abrasions on the limbs. He was shocked and only semiconscious. From the neck wound came a scanty but steady trickle of blood. An exp;oration was attempted under general anaesthesia, but it had to,be abandoned because the patient's respiration became sery "difficult" and the threat of asphyxia grew. Intubation was attempted but not accomplished. The presence of glottis oedema was suspected. Subsequently the onset of " cerebral irritation " was noted; his pulse rate rose from 70 on admission to 120 four hours afteithe operation. A cranio-cerebral injury was suspected, and accordingly he was transferred to Hurstwood Park Hospital. The findings here were as follows.


Objective To study the association of clinicopathological characteristics and surgical procedure with the prognosis of thyroid microcarcinoma.MethodsPatients with clinicopathologically diagnosed thyroid microcarcinoma(n=45) were enrolled for the analysis of clinicopathological characteristics and surgical procedure.Patients were followed up for the evaluation of prognosis.ResultsThe pathological type of thyroid microcarcinoma in 45 patients was papillary carcinoma,including bilateral multifocal carcinoma(n=8).Among 45 patients,38 underwent total resection of the affected lobe plus subtotal resection of the contralateral lobe,two underwent bilateral total resection,one underwent total resection of the affected lobe and isthmus lobectomy,two underwent total resection of the affected lobe plus isthmus lobectomy and partial resection of the contralateral lobe,and subtotal resection of the affected lobe.Seventeen patients underwent synchronous cervical lymph node dissection whereas no lymph node metastasis was detected.Patients were followed up for 6~77 mo,showing no recurrence or metastasis.ConclusionThyroid microcarcinoma has a favorable prognosis and a low rate of lymph node metastasis.The preferred procedure should be bilateral total resection or total resection of the affected lobe plus isthmus and contralateral lobectomy.Prophylactic cervical lymph node dissection is performed as routine.


Ruminant livestock production in North Dakota, South Dakota, Montana, and Wyoming is critical to the region's economy. Because of the economic significance of ruminant livestock production, producers in the four-state area are continually looking for opportunities to increase income and improve the viability of their farm and ranch operation. Accordingly, the Four-state Ruminant Consortium, an integrated research and extension program, was created to specifically address issues related to ruminant livestock production. The purpose of the Four-State Ruminant Consortium is to enhance economic development in the target study area of southwestern North Dakota, northwestern South Dakota, southeastern Montana, and northeastern Wyoming by strengthening and capturing value from the ruminant livestock industry. This study sought to identify opportunities for and constraints to expanding value-added enterprises within the beef cow-calf sector. A number of sources were utilized in assessing opportunities and impediments to adopting value-added beef enterprises. A mail questionnaire was delivered to 5,270 livestock producers in 37 counties in the 4-state study area of southwestern North Dakota, northwestern South Dakota, southwestern Montana and northwestern Wyoming. The questionnaire was designed to solicit a wide variety of information about operators' current production practices, including marketing, backgrounding, retained ownership, herd management and feed and forage practices. Following the survey, focus group interviews were conducted with groups of producers in each of the four states. Other individuals knowledgeable about other aspects of the region's livestock industry such as auction manager, banker, feed dealers were also interviewed. The results detailed in this report are a combination of a summary of key findings from the written questionnaire and findings from the focus group meetings. Findings from the focus group meetings are detailed in terms of opportunities and constraints and key themes articulated by focus group and interview participants.

Cotton (Gossypium hirsutum L.), one of the key crops of Pakistan, is responsible for the livelihood of a huge number of people across the country (Ahmad, 2003). This fiber crop is  cultivated on about 2699 thousand hectares area with an -1 average yield of 752 kg ha and lint production of 11935 thousand bales. Cotton products contributes about 5.5% to the value added in agriculture and approximately 1% to gross domestic product (GOP, 2018). Irrespective of the fact that Pakistan holds fourth position regarding cotton production, it lies far behind in term of average per hectare yield of cotton crop compared to other major cotton producing countries (Khan et al., 2011). Among other prominent constraints in cotton production, insect pest attack is one of the leading causes. Cotton crop is infested by a number of different sucking and chewing pests both at vegetative and reproductive stages (Yunus et al., 1980). Thrips tabaci (Lindeman), aphids, Aphis gossypii (Glover), whitefly, Bemisia tabaci (Gennadius), red cotton bug, Dysdercus koenigii (Fabricius) and dusky cotton bug, Oxycaranus hayalinipennis (Costa) are considered major sucking pests of cotton (Ahmad et al., 2002). Among the chewing pests, pink bollworm Pectinophora gossypiella (Saunders), American bollworm Helicoverpa armigera (Hubner), spotted bollworm Earias vittella (Fabricius) and Army worm, Spodoptera litura (Fab) are the major menaces (Khan et al., 2011). These insect pests are usually suppressed by the application of broad spectrum pesticides that are continuously deteriorating the environment (Hassan, 1992). Many of the synthetic pesticides are interfering with the endocrine system of living organism thereby leading to infertility, carcinogenesis and mutagenesis (Dinham, 1993). The widespread application of toxic chemicals to most agro-ecosystems provide a way to the dissemination of these poisons to soil, aquifers and water systems of most agricultural habitat. In the long term this could cause colossal losses to human health, wildlife and the environment. Consequently, there is a dire need to substitute pesticides with the use of other pest control methods that are environmentally safe and economical (Mohammad et al., ABSTRACT ARTICLE INFORMATION


Neutron shell-structure and the resulting possible deformation in the neighborhood of neutrondrip-line nuclei are systematically discussed, based on both bound and resonant neutron oneparticle energies obtained from spherical and deformed Woods-Saxon potentials. Due to the unique behavior of weakly-bound and resonant neutron one-particle levels with smaller orbital angularmomenta l, a systematic change of the shell structure and thereby the change of neutron magicnumbers are pointed out, compared with those of stable nuclei expected from the conventional j-j shell-model. For spherical shape with the operator of the spin-orbit potential conventionally used, the lj levels belonging to a given oscillator major shell with parallel spinand orbital-angularmomenta tend to gather together in the energetically lower half of the major shell, while those levels with anti-parallel spinand orbital-angular-momenta gather in the upper half. The tendency leads to a unique shell structure and possible deformation when neutrons start to occupy the orbits in the lower half of the major shell. Among others, the neutron magic-number N=28 disappears and N=50 may disappear, while the magic number N=82 may presumably survive due to the large l = 5 spin-orbit splitting for the 1h11/2 orbit. On the other hand, an appreciable amount of energy gap may appear at N=16 and 40 for spherical shape, while neutron-drip-line nuclei in the region of neutron number above N=20, 40 and 82, namely N ≈ 21-28, N ≈ 41-54, and N ≈ 83-90, may be quadrupole-deformed though the possible deformation depends also on the proton number of


In this study, fracture analysis of a fibrous composite laminate with variable fiber spacing is carried out using Jk-integral method. The laminate is assumed to be under thermal loading. Jk-integral is formulated by using the constitutive relations of plane orthotropic thermoelasticity. Developed domain independent form of the Jk-integral is then integrated into the general purpose finite element analysis software ANSYS. Numerical results are generated so as to assess the influence of variable fiber spacing on mode I and II stress intensity factors, energy release rate, and T-stress. For verification, some of the results are compared to those obtained using displacement correlation technique (DCT). Keywords—Jk-integral, variable fiber spacing, thermoelasticity, t-stress, finite element method, fibrous composite.


The inclusion of perennial groundcover (PGC) in maize production offers a tenable solution to natural resources-related concerns associated with conventional maize; however, insight into system management and key information gaps is needed to guide future research. We therefore extended the Agricultural Production Systems sIMulator (APSIM) to an annual and perennial intercrop by integrating annual and perennial APSIM modules. These were parameterized for


On page 7993, C. Merschjann and co-workers use transient photoluminescence to study charge transport in semiconducting polymeric graphitic carbon nitrides, finding that electrons and holes show surprisingly high mobilities. Furthermore, they move predominantly along channels perpendicular to the graphitic sheet structure. Thus, carbon nitrides effectively complement 2D materials like graphene, opening potential routes for novel organic electronic devices.


A new method for discrimination of varieties of Chinese bayberry by means of infrared spectroscopy (NIRS) (325-1075nm) was developed. A relation has been established between the reflectance spectra and Chinese bayberry varieties. The dataset consist of a total of 69 samples of Chinese bayberry. First, the data was analyzed with principal component analysis. It appeared to provide the best clustering of the varieties of Chinese bayberry. PCA compressed thousands of spectral data into a small quantity of principal components and described the body of spectra; the scores of the first 20 principal components computed by PCA had been applied as inputs to a back propagation neural network with one hidden layer. 69 samples contained three varieties were selected randomly, then they were used to build BP-ANN model. This model had been used to predict the varieties of 15 unknown samples; the residual error for the calibration samples is 1.508458 x 10-6. The recognition rate of 100% was achieved. The result achieved by using PCA-BP method is much better than the results achieved by only using the PCA method. This model is reliable and practicable. So this paper could offer a new approach to the fast discrimination ofvarieties of Chinese bayberry.


Objective : Pseudotumor cerebri is a disorder of unknown etiology that results in raised intracranial pressure (ICP) and characterized by attendant signs and symptoms of increased ICP in an alert and oriented patient but without localizing neurologic findings. Vestibular evoked myogenic potentials (VEMPs) are short latency reflex responses produced by stimulation of the vestibular apparatus. The purpose of this study was to determine whether group of pseudotumor cerebri patients have abnormal changes in VEMPs (cervical and ocular) and to analyze the results and compare them with matched group of normal subjects. Design : Ocular and cervical VEMPs were performed to the entire study groups. The responses were obtained from thirteen pseudotumor cerebri patients and compared to fifteen age matched normal subjects. All participants were subjected to audiological assessments that include pure tone audiometry, tympanometry and acoustic reflexes. Results : Ocular and cervical VEMPs amplitudes were reduced in response in pseudotumor cerebri patients than normal but still of non-statistical significant difference p>0.05. Discussion and Conclusion : The results of this study suggest that patients with pseudotumor cerebri do not have statistically significant changes in comparison with the normal control as regard ocular and cervical VEMPs testing. Hence, asserting a query whether there is affection of VEMPs in pseudotumor cerebri patients.


A one-pot continuous-flow method for hydrogen (deuterium) generation and subsequent hydrogenation (deuterogenation) was developed using a stainless-steel (SUS304)-mediated ball-milling approach. SUS304, especially zero-valent Cr and Ni as constituents of the SUS304, and mechanochemical processing played crucial roles in the development of the reactions.


Security is a main concern for any ad hoc network (like MANETs, VANETs, IOT etc.) as they are vulnerable to various kinds of attacks. Most of the popular protocols for detecting and mitigating the attacks, will process only after the commencements of attack. Instead of reactive measures, preventive measures are worthy, as they attempts to defend the attacks before it can happen to damage the performance of the network. However, both types of methods can be implemented either by collective effort of collaborative network nodes (i.e built-in protocols added by security messages) or by internal evaluation of the attack state. This paper proposes a technique for minimising (reducing) the Gray-hole DOS attack. This technique does not assume any explicit-node collaboration and relies only on internal knowledge of each node achieved by regular routing information. This technique was tested through five different threat models with variable attacker capacities, which allows better realization of base of the attack as well as its prevention the protocol in simulated in NS-3 simulator and the results demonstrate a reduction up to 55% in number of dropped packets, indicating great defence for Gray-hole attack on thee MANETs as the MANETs application are evolving in phenomenon way for the last two decades, they are emerging in the new technologies like VANETs and IOT as standalone network tool. 1 International Journal of Pure and Applied Mathematics Volume 118 No. 24 2018 ISSN: 1314-3395 (on-line version) url: http://www.acadpubl.eu/hub/ Special Issue http://www.acadpubl.eu/hub/


The leafhopper Empoasca vitis (Goethe) (Homoptera: Cicadellidae) is a serious pest in European vineyards. The assessment of economic damage caused by E. vitis was associated with no definite results probably because of a different susceptibility and sensibility of grape cultivars to the
pest. Empoasca vitis abundance and symptoms associated with the activity of this pest were evaluated during three years on 10 grape cultivars grown in collections located in north-eastern Italy. Empoasca vitis densities were estimated from May-June to September by sampling leaves every 7-10 days. At vintage time, the percentage of leaf surface with symptoms caused by E. vitis feeding was estimated. Carmenere, Sauvignon Blanc and Tocai Friulano showed to be very susceptible and very sensible, whereas Cabernet Sauvignon, Chardonnay, Verduzzo Friulano and Pinot Gris showed an opposite behaviour. However, such correspondence was influenced by meteorological conditions and plant stress factors. These results may be useful for establishing economic thresholds and sampling plans for E. vitis in vineyards.

This paper is to realize digital corrector magnet power supply based on FPGA. The purpose of the study is to implement digital PID controller by using Xilinx programmable gate array (FPGA), in hope of enhancing output performance and reducing circuit size. The ±10A/± 48V output corrector magnet digital FPGA power converter uses a full bridge configuration, the switching frequency of power MOSFET is 40 kHz, in which each bridge leg has its own independent PWM controller and the output current bandwidth is 1kHz when connected with the corrector magnet load. Using a DCCT as the current feedback component, the output current ripple of this converter could be lower than 10ppm. In this paper, the hardware structure and control method of the corrector magnet power converter will be described and the test results will be demonstrated.

To compensate for high pathloss and improve coverage in millimeter-wave (mmWave) frequencies, highly directional transmit (Tx) and receive (Rx) beamforming is required. In addition, mmWave frequencies are extremely susceptible to blockages, and when blockage occurs, the link between Tx and Rx may be terminated and an alternate path is required to retain communication. Reconfigurable intelligent surface (RIS) can be considered as a possible solution to not only solve the blockage problem but also to cover dead spots. However, using conventional exhaustive search protocol, the overhead of beam training increases exponentially with the number of RIS reflective beams, as it requires finding the optimal beam pair in the Tx-RIS-Rx link. In this paper, a low-latency retro-reflective (LLRR) beam training protocol for RIS-assisted cellular system is proposed to reduce the overall beam training time by reflecting the RIS beams to the source. Furthermore, the feasibility of the RIS element to provide 180° phase shift is analyzed. Simulation results show that the proposed LLRR beam training significantly reduces the training time compared to the state-of-the-art and achieves gains of ≈ 1.5 bps/Hz and ≈ 9.8 bps/Hz at signal-to-noise ratio of 15 dB when the number of beams at RIS is 64 and 256, respectively.

Why did Germany pursue naval expansion at the turn of the twentieth century? This question has long puzzled scholars of international security, who consider German naval ambition to be an instance of suboptimal arming—a decision that decreased Germany's overall security and risked the survival of the German state. This article argues that the social desire to be recognized as a world power guided Germany's decision to challenge British naval hegemony. From the beginning of its naval planning, Germany had one clear aim: a powerful fleet of battleships stationed in the North Sea would alter the political relationship with Britain in such a way that it could no longer ignore Germany's claim to world power status. Reconceptualizing Germany's naval ambition as a struggle for recognition elucidates the contradictions at the center of German naval strategy, explaining how the doomed policy could proceed despite its certain failure. The article concludes that the power-maximizing practices of great powers should be seen as an important component of identity construction and an understudied dimension of contemporary security practice.


This is the catalog of one of the two USAmerican artists represented at the 1978VeniceBiennial Exposition, whose theme was From Nature to Art and from Art to Nature. In her compact accompanying essay, Cathcart presents information helpful towards an understanding of the work of Richard Diebenkorn. While the 16 paintings and 10 drawings selected for exhibition and reproduced in the catalog were drawn from his 'Ocean Park' series (dating from 1967 to 1978), she deals primarily with his earlier works that serve as a base for an appreciation of his most recent work. She relies, perhaps too much, on quotes from Diebenkorn and from other writers, nevertheless her deft organization of the material and her own interpolations reveal not only an obvious sympathy for the artist's work but also an understanding of the purposefulness behind the moves Diebenkorn has made to obtain the recognition he has achieved. At the very least, the inclusion of these other writers' comments from the past two decades points up her contention that 'Diebenkorn has never been neglected as a painter' and that it became apparent very early that his development would be worth following. Ironically, early criticism had also to deal with Diebenkorn's unbalanced acknowledgement of his roots in the work of, for example, Hopper and Matisse, his own insistent description of himself as a 'traditional painter', an implied distrust of anything redolent of the 'avant-garde', and his emigration from New York City at a time when many eyes were focused on the art scene there. As to exactly 'where he is today', the paintings and drawings included in the catalog speak most eloquently for the artist and serve equally well as witnesses to the logic of Diebenkorn's development (as reconstructed by Cathcart). Although his sensibilities have surely changed over the years, I find his openness to the possibilities of painting remarkable. It is particularly this openness, which he has termed his 'negotiations' with painting, that lies near the heart of any appraisal of his work. Throughout her essay Cathcart builds on the apparent paradox of a painter in search of a way to arrive at a method that will best keep the method from dominating his work. The portrait is that of an artist aware of both the need to establish guidelines and the need to go beyond them, if one is to continue one's development as an artist and a person.


The objects of this study are to present new gas seals, which have several control fins at a groove part of straight labyrinth seal, and to evaluate the dynamic characteristics of the seals experimentally and theoretically. The new seals are expected to reduce the tangential velocity and to control the instability of the rotor system. The experimental test results are presented for eight multiple-pocket grooved gas seals with different number of control fins and stages to put control fins. In the theoretical study, seal chamber is divided into two control volumes. Then, the equations are formulated for each control volumes. The fluid forces acting on the rotor are obtained. For the circumferential velocity, the groove part is divided into three control volumes then the decrease in circumferential velocity by the effect of the control fins is evaluated at each control volume. Then, the circumferential velocity and dynamic fluid force were measured for 8 types of seals which were changed the number of fins and location of the fins in the experiment. In the theoretical analysis the flow equation which suppress the circumferential velocity was taken into account in the conventional labyrinth seal equation and solved numerically. From the above experimental and theoretical investigations, the followings are concluded that control fin installed in the grooves is effective to suppress the circumferential velocity. The effect of the fins is large at the first and second stage from the inlet of a seal. The effect of fins on the stabilization of rotor was large for 8 and 4 fins in the first stage.


QUAL2K enhanced QUAL2E and applied in real fields efficiently incorporates denitrification process, sediment-water interaction process, bottom algae and detritus. Also, the CBOD of QUAL2K is divided into two real parts, one is slow CBOD(sCBOD) and another is fast CBOD(fCBOD). The simulation results of QUAL2E and QUAL2K models in Anyang Stream were compared and analyzed in water quality constituents of DO, BOD, Org-N, NH-N, NO-N, Org-P, Dis-P and Chl-a respectively. The similar results were shown in Org-N, NH-N, Org-P and Chl-a both QUAL2K and QUAL2E models. But the different results were revealed in DO, BOD, Dis-P and NO-N by the influence of new incorporating processes. DO was shown relatively low values in the effect of bottom algae. BOD which is influenced by particulate organic matter was revealed high values. NO-N was closed to the real values by the two processes of denitrification and sediment-water interaction. To evaluate the running results of QUAL2K and QUAL2E models, a simple statistical analysis was conducted. According to the statistical analysis, QUAL2K represented less relative error and coefficient of variation than QUAL2E in almost all of constituents. It was found that QUAL2K, which simulates the water quality more realistically, can be applied to control and manage the water problems of river or river-run reservoir effectively.


ABSTRACT
 Diadromus collaris (Gravenhorst) is an important pupal parasitoid of the diamondback moth, Plutella xylostella (L.), a major insect pest of cruciferous vegetables worldwide. We studied the development of immature stage of D. collaris by dissecting parasitized hosts in the laboratory at 25 ± 1°C and 50–80% relative humidity. The results show that all immature stages complete their development within the same host in 11≈12 d. The egg is hymenopteriform and appears to be anhydropic. There are four larval instars. The first instar is transparent with a sclerotized rectangular chitinous head capsule and distinct mandibles. Head capsule of the second instar turns into more isosceles trapeziumshaped. The third instar looks similar to the second instar but proportionally much larger. The sclerization and dimension of the fourth instar increases significantly. The pupa is a typical exarate form and lacks a cocoon. All life history was fully documented with detailed photomicrographs. Our study will be useful for understanding the physiological interactions between D. collaris and P. xylostella.


For traditional rotary burrs, cutter teeth converge at the vertex, which means small chip space and poor cutting condition. In order to increase the chip space and to improve the cutting condition, a new type of rotary burrs with partition blade teeth, which took the feasibility of the actual process into consideration, was proposed. The curve planning algorithm planned the blade curves on the tooth bottom contour surface, and adjusted the tooth bottom contour model by some parameters, such as the small central angle and the position of oblique planes, to control the contour and blade shape for rotary burrs effectively. Experimental results demonstrate the effectiveness of the proposed algorithm.

The reason why high temperature superconductivity has been being debated is that many basic ideas in literatures are wrong. This work shows that the magnetic flux quantum in a superconducting ring have been inaccurately explained in fact, thus we suggest a reinterpretation of the magnetic flux quantum in a superconducting ring on the basis of the translations of pairs. We also predict that the internal and external surface of a superconducting tube have the reverse circling supercurrents. This means that a more thick tube could trap a larger amount of flux. Both the magnetic flux quantum and the reverse circling supercurrents could not be found with the London equation.


The Situational diagnosis of the population in the area of health family unit Professor Ib Gatto Falcão, in Marechal Deodoro-AL, made possible the identification and choice of difficulty of glycemic control of diabetic patients, whose treatment adherence is low, as the main problem to be solved. This study was conducted with the objective of elaborating a project for improving glycemic control of diabetic patients in the area covered by this health unit. The intervention project, therefore, will define strategies in order to increase the compliance to therapy to improve glycemic control of diabetic patients and reduce the incidence of complications in the future. From the prioritization of problems identified in the Situational diagnosis, for conducting the study was conducted at first a literature review and later the development of an action plan for control of diabetic patients based on the Situational strategic planning assumptions. Strategic action planning for integral care of diabetics aims to improve the quality of care to the carrier of chronic disease and reduce the morbidity and mortality between them. The training of health staff to develop educational activities on the treatment of diabetes mellitus is essential for patients to have greater knowledge about your diagnosis, the risks of non-adherence to treatment and the importance of self-care.

Purpose: The purpose of this paper is to investigate the linguistic construction of the femininity for girl characters in Indonesian folktales retold in children's books. During the phase of their lives as girls, female characters in Indonesia folktales are narratively bound up in attempts to confront, fulfill, and sometimes defy, social prescribed feminine roles.
Methodology: The data are twenty Indonesian folktales depicting girls as the main characters. The lexical, as well as clausal constructions in the stories in relation to girls are analyzed using content analysis and Halliday's transitivity within the framework of Systemic Functional Linguistics.
Results: The results show that ideal femininity attributed to girls in Indonesian folktales are mainly of three dimensions
i.e. beauty, virtue, and passivity. The lexical representation of girl femininity reveals that girls in Indonesian folktales are typically stereotyped with either traditional femininity or non-conforming femininity.
Implications: The clausal analysis shows how the stories present the attempt of the girls to fulfill the ideal feminine roles. There seems to be a reward for girls who fulfill 'proper' feminine qualities and punishment for girls who defy the ideal femininity. However, there are girls who seem to be non-conforming to the ideals of traditional femininity but rewarded as well as girls who fail at feminine roles but not punished with the provision of forgiveness. Thus, this paper contributes to the discussion on the girlhood femininity in contemporary children's books.


The peripheral arterial disease (PAD) and the critical limb ischemia (CLI) are frequent and serious pathologies in dialysis, in both diabetic and non-diabetic patients, and represent serious clinical and social problems. Patients having serious trophic injuries often have to recur to amputation, despite the use of all the therapies that are currently available. In this article we attempt to underline the importance of the microcirculation and rheopheresis in affecting the prognosis of this pathology.

Even the tiniest keyhole surgery could be carried out using nanoscale computer-controlled surgical instruments.


We theoretically investigate the effects of Gallium Arsenide (GaAs) as an absorbing material in a complex waveguide structure model. Finite Difference Time Domain (FDTD) method is used to discretize the Maxwell's curl equations for the proposed structure. A comparison between Amorphous Silicon (a-Si) and GaAs as absorbing materials is presented through the computation of the absorption spectra. It has been realized that GaAs is still a promising candidate to be used in the waveguide structure models through maximizing the absorption and minimizing the reflectance in the proposed waveguide structure.


Tests were run to determine the static pressure forces present on the surface of the stern seal of the XR-3 surface effects ship testcraft. These experimentally determined forces were resolved into lift and drag following a determination of stern seal shape at each of the test speeds. The lift and drag determinations cannot yet be meaningfully related to total drag of the craft, but they provide an isolated look at direct effects of plenum chamber overpressures while varying speed. The unique variations of seal position and shape with changes in velocity, noted and documented during this project, may present new difficulties in attempts to analytically model and evaluate seal performance.


The purpose of this study was to examine the extent to which beginning teachers who are career changers hold proactive beliefs about teaching. The beliefs of six career-changers (four males and two females, aged 25 to 45 years) were examined by means of in-depth interviews concerning their academic histories, previous careers, teacher preparation experiences, and general philosophy about school improvement. Cross-analysis of the qualitative data resulted in a Conceptual Framework toward Change. This framework suggests that career changers may be proactive in their approaches to teaching to the extent that they are capable of: (1) identifying with the new role of teacher; (2) having an investigatory focus on their work in the classroom; and (3) resolving developmental issues in their personal lives.

The aim of this paper is to show particular sensitivity of the flow part of the marine turbine engine to the presence of contaminants in the intake air. The contaminants form hard-to-remove deposits in the intervane channels that result in a reduced efficiency and performance of the engine. The paper classifies the contaminants according to the source of their formation and their destructive force. The performed analyses and syntheses of the discussed problem have been complemented with the results of own endoscopic research of the flow part of various types of marine turbine engines.

Abstract : This Strategy Research Project (SRP) proposes a concept to merge both the United States Army Recruiting Command (USAREC) and the United States Army Cadet Command into one accessions organization. For the past five years both USAREC and Cadet Command have found greater difficulty in achieving their annual missions. USAREC, except for FY 00, has missed its recruiting mission for five years straight and Cadet Command failed in its commissioning mission this past year. Now with the establishment of a formal partnership' between USAREC and Cadet Command and with recruiters sharing office space with ROTC cadre on college campuses, its appropriate to ask the question--why two commands? Could the redundancy and inefficiency of these two organizations actually be impeding on their ability to recruit? Are there too many hand-shake' agreements/partnerships? Perhaps there needs to be a formal command structure that provides command and control by a higher headquarters that is responsible for both missions--officer and enlisted recruiting. How much money and resources could be conserved by sharing these efforts? Could redundancies in staffs cause the reduction in resources if commands and staffs were merged? In a time when the Army is geared towards Transformation and looking at ways to move resources from the institutional army to the warfighting commands--to put troops back in the foxholes--eliminating redundancy and inefficiency in institutional Army organizations like USAREC and Cadet Command make sense. This reorganization is more than a new organization. It proposes a whole new way of doing business--'a new philosophy.' With this concept of total Army recruiting, all green-suitors participating in the recruiting effort, one recruiting' organization will be able to systematically penetrate a lost market segment' of high quality young people.


The current and projected climate change that is represented by increasing temperatures, humidity levels and irregular rainfall patterns, promotes the occurrence of preharvest sprouting (PHS) in wheat. PHS results in significant economic losses, globally, which necessitates the need for high-yielding cultivars with increased PHS tolerance, hence this study was conducted. The current study evaluated two doubled-haploid (DH) wheat populations of Tugela-Dn × Elands and Elands × Flamink across six environments in the Free State Province of South Africa to select genotypes with increased PHS tolerance and further map the underlying loci. Significant effects of DH lines (194) and environments (6) were observed for PHS tolerance. The results of this study validate previous findings that PHS is only expressed when environmental conditions are conducive. Quantitative trait loci (QTL) mapping using single nucleotide polymorphism (SNP) and silicoDArT markers revealed three additive QTL with major effects on chromosomes 5B and 7B, and these QTL were detected more than once, when conditions were favourable. These QTL explained a phenotypic variation (PVE) varying between 10.08% and 20.30% (LOD = 2.73 – 3.11). About 16.50% of DH lines performed to the level of Elands (the PHS-tolerant parent) and are recommended for further selection in a pre-breeding or breeding programme. The findings of the study are expected to facilitate the on-going breeding efforts for PHS tolerance in winter wheat.

T HE chronology of Richard Strauss's artistic life up to the present time arranges itself almost irresistibly in the traditional three periods, albeit in his case the philosophy of these periods has to be rather different from that, say, of Beethoven's. "Discipline, maturity, eccentricity," we say with sufficient accuracy in describing Beethoven's development. The same formula for Strauss will perhaps be tempting to those for whom the perverse element in the Salome-Elektra period is the most striking one; but it is safer to say simply: "Music, program music, and music drama." Born in 1864, he produced during his student years, up to 1886, a great quantity of well-made and to some extent personal music, obviously influenced by Mendelssohn, Schumann, and Brahms, and comprising sonatas, quartets, concertos, and a symphony. He himself has told how he then came under the influence of Alexander Ritter, and through him of Wagner, Berlioz, and Liszt; how this influence toward "the poetic, the expressive, in music" acted upon him "like a storm wind"; and how the "Aus Italien," written in 1886, is the connecting link between his earlier work and the series of symphonic poems that follows in what I have called the second period. The chief titles and dates of this remarkable series may be itemized here: "Macbeth," 1886-7; "Don Juan," 1888; "Tod und Verklarung," 1889; "Till Eulenspiegel" and "Also Sprach Zarathustra," 1894; "Don Quixote," 1897; "Ein Heldenleben," 1898; and the "Symphonia Domestica," 1903. The period of program music, containing also, of course, other works such as the operas "Guntram" and "Feuersnot," innumerable songs, and a violin sonata strayed from the first period, thus lasts from his twenty-second to his thirty-ninth year. Strauss is now fifty-one. He has devoted the past decade chiefly to works for the stage, comprising "Salome" (1906), "Elektra" (1908), "Der Rosenkavalier" (1911), "Ariadne auf Naxos," (1913), and "Josephs Legende" (1914). His latest work is again in the province of instrumental music-an "Alpine Symphony."

In this work, the gas-phase homolytic N−H bond dissociation enthalpy (BDE) was investigated for a large series of molecules containing at least one N−H bond by means of accurate density-functional theory calculations. The molecules studied belong to different classes of compounds, namely, amines, amides and anilines, amino acids, phenoxazines, indolamines, and other compounds of general interest, such as anti-inflammatory drugs. To achieve these purposes, the (RO)B3LYP/6-311+G(2d,2p)//(U)B3LYP/6-31G* level of theory was used. The calculated gas-phase N−H BDEs, at T = 298.15 K, are in the range 499.6−203.9 kJ/mol, for purine and HNO, respectively. Further, the calculated BDEs are in excellent agreement with a significant number of available experimental BDEs. Solvent effects were also taken in account, and rather significant differences are found among N−H BDEs computed in the gas phase and in heptane, DMSO, or water.

The article presents and emphasises any early actions and planned activities taken to support
the development of children who are in the early stages of development visible symptoms of atypical
brain development (ABD). The methods and forms of early therapeutic intervention and its impact
on children's development are discussed on the selected case studies. It should be pointed out that the
need for multidisciplinary diagnosis of children and then the consequences of the lack of specialised
holistic therapy, which should be implemented are also indicated in the article. What is more, the article
presents a proposal for "Therapeutic work program for children with ABD", containing physical development,
visual perception and spatial orientation, speech and thinking development and improvement
of reading skills. The above-mentioned program is a good example of supporting the early development
of children from infancy period till a primary school period.


Abstract A new buffer pH method (BpH) for the rapid estimation of unbuffered salt‐exchangeable acidity (ACe) and lime requirement (LR) has been developed. The buffer reagent, consisting of sodium glycerophosphate, acetic acid, trletlianolamine, ammonium chloride and barium chloride, was useful within the pH range 3.8 to 6.6. Delta values from BpH were converted into buffer pH acidity values (AC) and calibrated against ACe of 91 mineral soils and 100 acid Histosols. The correlation coefficients between AC and ACe were 0.966 and 0.956 for the mineral soils and Histosols, respectively. The corresponding regression equations in terms of meq/100 cm were ACe ‐ ‐0.54 + 0.96 AC and ACe = ‐7.4 + 1.6 AC for mineral soils and Histosols, respectively. To predict lime requirement of mineral soils a curvilinear equation was required. The equation, LR in meq CaCO3/100 cm3 = 0.1 (AC)2 + AC, was tested successfully against rates of lime carried out under laboratory conditions and against crop response in the greenhouse. F...


One of the opportunities offered by the Internet is the ease of distributing digital products; such is the case that a large part of the productive sectors hasused the network as a natural means of information exchange. The use of digital documents, in addition to facilitating their distribution and management, allows their transformation well or maliciously by the community of users of the product. As a result, new problems arise regarding the implementation of copyright and distribution rights in digital content. This researchattempts to addresstheissue related to security in digital documents, which in recent times have been increasing. It will explain what is Fingerprinting regarding to help to protect copyright, as well as its most commonly used techniques. Going through the need of its implementation until reaching the explanation of these tools. All this to raise awareness about how you can try to protect these rights, but emphasizing that currently there is no 100% method capable of avoiding piracy.

In this paper, we give difference equations on fractal sets and their corresponding fractal differential equations. An analogue of the classical Euler method in fractal calculus is defined. This fractal Euler method presets a numerical method for solving fractal differential equations and finding approximate analytical solutions. Fractal differential equations are solved by using the fractal Euler method. Furthermore, fractal logistic equations and functions are given, which are useful in modeling growth of elements in sciences including biology and economics.


ABSTRA C T We use data from the Rossi X-ray Timing Explorer to search for harmonics and sidebands of the two simultaneous kilohertz quasi-periodic oscillations (kHz QPOs) in Sco X-1. We do not detect any of these harmonics or sidebands, with 95 per cent confidence upper limits to their power between ,1 and ,10 per cent of the power of the upper kHz QPO. The oscillations produced at these frequencies may be attenuated in a scattering corona around the neutron star. We find that upper limits to the unattenuated power of some of the strongest theoretically predicted harmonics and sidebands are as low as ,2 per cent of the unattenuated power of the high-frequency QPO in Sco X-1.

The thirteenth edition of Madeira, Canary Islands, and Azores8 has been revised and brought up to date, and the author, Mr. A. SAMLER BROWN, is to be congratulated on improving still more a very valuable and interesting guide.book to these islands, which are rightly increasing their popularity as health and holiday resorts. The climate, historv, geographv, social conditions, means of transport, and such matters are dealt with comprehensively, and the book is illustrated with photographs, maps, and diagrams. Special attention has been given to the requirements of invalids of different kinds, and medical practitioners who wish for information in this respect will find the book helpful. It may be suggested that the subject of pronunciation deserves a little more attention, two short paragraphs on an otherwise blank page being intriguing, but inadequate for those who would like to arm themselves with a few phrases in Portuguese or Spanish before landing.


Only a complete approach can be expected to yield successful results in the treatment of dermatologic disorders. Requisites are definitive diagnosis if possible, adaptation of the mode of therapy to the patient's way of life, careful selection of remedies, and thorough instruction of the patient regarding their application and removal as well as what he can and cannot do during the treatment period. An essential and often overlooked component of therapy is the choice of an appropriate vehicle for topical medication.

Little attention has been paid to knowledge as a context of computer-mediated communication (CMC) and to differences in meaning attributed to the same message when located in different contexts. Drawing on concepts in anthropological usage and on those used in other disciplines, especially the constructs of "common ground" and "relational cultures," this paper addresses that gap. It examines in instant messaging, a particular mode of computer-mediated communication, how individuals with different kinds of knowledge interpret online interaction.


The invention discloses an electric heating smokeless barbecue stove. The electric heating smokeless barbecue stove comprises a stove body housing and a heating unit fixed at the lower part of the housing. A barbecue wire mesh is erected on a stove body. An inner container with high thermal radiation reflection rate is arranged in the housing. The bottom of the inner container is provided with a through hole. A heating tube of the heating unit penetrates through the through hole and surrounded by a cavity of the inner container. The inner container can be detachably put in the housing. A baffle board is correspondingly arranged right above the heating tube.

The first stages of the growth of Co on Cu ~111! are studied by means of scanning tunneling microscopy. By measuring island densities for several deposition rates, information about the diffusion coefficient on the terraces is extracted. The barrier for edge diffusion is estimated from the shape of the islands. Finally, the relevant Ehrlich-Schwoebel barriers for interlayer mass transport are estimated from the onset of step-flow growth mode and top layer nucleation density. The barriers are determined by comparison with simple physical models. The implications of the figures obtained for the heteroepitaxial Co/Cu ~111! system are discussed.


: The development of a mild and practical Barbier-Negishi coupling of 2° alkyl bromides with triflates and nonaflates is reported. This challenging reaction was enabled by a very bulky imidazole-based phosphine ligand, which allowed achieving good yields, chemo- and site-selectivities for a broad range of substrates at room temperature and under non-aqueous conditions. This reaction was extended to 1° alkyl bromides by using an analogous pyrrazole-based ligand. phosphines using L 9 as the the Barbier-Negishi coupling of 1° alkyl bromides 11a-d with nonaflate 10a in excellent yields 2). and This practical was extended to 1° alkyl bromides pyrrazole-based and nonaflates was performed at room temperature with good chemoselectivity and limited isomerization in the presence of a very bulky phosphine ligand.


Evaluation ofArteriography in Invasive Trophoblastic Neoplasia Arteriography provides visual localization of a disease process which in some instances is known to be present only by virtue of its production of chorionic gonadotrophin. It may also demonstrate metastatic disease in the pelvis which is undetectable by any other means. Pelvic arteriography is sometimes of value in selecting patients for hysterectomy. Where chemotherapy has eradicated identifiable metastases, and residual disease persists as evidenced by hormonal criteria and local arteriographic abnormalities in the pelvis, hysterectomy has proved successful in final elimination of the disease in some patients (Bagshawe 1969). While improvement in arteriographic appearances accompanies a favourable response to treatment, abnormalities may persist long after any clinical and biochemical evidence of disease. Persistent arteriovenous shunts following successful chemotherapy have been previously reported (Hendrickse & Cockshott 1967) and have been noted in several of our patients. In two cases they have contributed to torrential menorrhagia necessitating hysterectomy. Arteriographic features of pregnancy and ITN show considerable overlap, with dilated intramural arteries, irregular vascular spaces with frayed margins, and delayed emptying in both conditions (Fernstrom 1955). Interstitial tubal pregnancy (Borell et al. 1966), placenta accreta and missed abortion (Hendrickse et al. 1964, Borell & Femstrom 1961) have similar appearances with enlarged vascular intervillous spaces and occasional round avascular areas surrounded by a pale vascular blush. Extrauterine abdominal pregnancy (Haber & Wilson 1965, Dilts 1966) may be indistinguishable in the period prior to skeletal calcification from a metastasis of a trophoblastic tumour. In general it is not possible to distinguish between choriocarcinoma and invasive mole by arteriography, although filling defects due to hydropic villi can sometimes be defined. The abnormalities present in choriocarcinoma following full-term pregnancy tend to be less extensive than ITN following a hydatidiform mole. Gonadotrophin excretion has been a much more reliable guide to the presence of active trophoblastic disease than has pelvic arteriography in our series. Curettage has sometimes given valuable morphological evidence of trophoblastic disease although curettings are often normal in patients with abnormal arteriograms, presumably due to the intramural location of the tumour. Arteriography provides useful supplementary information about the presence and extent of invasive trophoblastic disease. The procedure is safe with no significant morbidity in the series of over 130 patients at Fulham Hospital, and radiological evidence of disease can be obtained in the presence ofhemorrhage from the uterus and from vaginal metastases. Despite its limitations, arteriography has widened our knowledge of the nature, growth and dissemination of invasive trophoblastic neoplasia.

In secondary underlay transmission in a host channel, the signal from primary transmitter produces high interference for secondary low power links. In this paper, we propose a primary interference suppression technique by using direct sequence spread spectrum. We show that secondary users can efficiently suppress the high power signal from a primary transmitter by using proper processing gains. Also, we propose a simple deployed underlay transmission scheme in a host channel for a secondary network. We show that by using primary interference suppression for direct sequence spread spectrum links our proposed transmission scheme achieves 186.09 Mbps and 362.73 Mbps capacity respectively at the center and at the edge of a primary cell when there are 60 secondary channel applicants in secondary network and processing gain is 100. Also, we show that the achieved capacity is gained without producing harmful interference temperature in the host channel and perceptible interference in adjacent channels.


This article presents a social-cognitive theory of substance abuse. The exercise of self-regulatory agency plays a central role in this approach. Perceived self-efficacy is the foundation of human agency. Unless people believe they can produce desired effects by their actions, they have little incentive to act. Self-efficacy beliefs promote desired changes through cognitive, motivational, affective, and choice processes. Perceived self-efficacy exerts its effects on every phase of personal change—the initiation of efforts to overcome substance abuse, achievement of desired changes, recovery from relapses, and long-term maintenance of a drug-free life. Assessments of perceived efficacy identify areas of vulnerability and provide guides for treatment. Substance abuse is a social problem, not just a personal one. Reducing substance abuse also requires policy initiatives and social remedies achieved through the exercise of collective efficacy.


The scientific and reasonable emergency logistics network,with strong economic and social benefits,is the foundation for emergency logistics to quickly come into effect.Based on the core philosophy of adaptive supply chain,we first give the conceptual model for adaptive supply network,and establish the emergency logistics network system,and divide its operation into four different stages which are routine management stage,emergency start-up stage,smooth operation stage aftermath handling stage.Then we analyze the change trend of significance for each objective that emergency logistics pursues in these stages,and introduce penalty function coefficients to strike a balance between emergency logistics'timeliness economy,risk.Finally,we build a network optimization model for emergency logistics to provide decision-making plans for the smooth,timely and secure delivery of emergency supplies.


As organizations increasingly depend on information technology for their operation, complexity of information systems becomes an important issue for management in the context of organizational engineering. This paper shows how the combination of cybernetics with conceptual modelling contributes to the measurement of complexity for the analysis and design of information systems and organizations. Based on the discussion of a language-based approach, we show how conceptual modelling as an instrument for organizational analysis can significantly contribute to organizational engineering if used in combination with an established theory for control and communication. Within an action case study in an information technology controlling setting, we apply the concept of variety as a measure for complexity in combination with conceptual modelling and explore its usefulness for the diagnosis and redesign of a controlling and reporting system.

Water-stress tolerance of six clones in a pedigree consisting of black cottonwood (Populustrichocarpa Torr. & Gray, female) and eastern cottonwood (Populusdeltoides Bartr., male) parental clones and four hybrid progeny was investigated. Trees were grown outdoors in pots; well-watered trees were kept moist (soil water potential greater than −0.03 MPa), and stressed trees (soil water potential less than −2.0 MPa) were subjected to repeated cyclical stress of 1 or 2 days duration over the 14-week study. Male P. deltoides and the male clone 242 displayed the greatest degree of stress tolerance, as evidenced by greater osmotic adjustment at saturation (0.25 MPa) and maintenance of relative growth rate of the main stem under water stress at 100 and 69% of that of well-watered trees, respectively, compared with reductions to 50–58% for the other hybrid clones. However, differences in total plant dry weight under water stress were less obvious, with female clones allocating more carbon to branch production under ...


Lawrence Lessig is professor of law at Stanford University. He is author of The Future of Ideas: The Fate of the Commons in the Connected World (New York: Random House, 2001) and Code and Other Laws of Cyberspace (New York: Basic Books, 1999). Who owns the Internet? Until recently, nobody. That's because, although the Internet was "Made in the U.S.A.," its unique design transformed it into a resource for innovation that anyone in the world could use. Today, however, courts and corporations are attempting to wall off portions of cyberspace. In so doing, they are destroying the Internet's potential to foster democracy and economic growth worldwide. | By Lawrence Lessig


Using information from the world values survey wave 6 containing information from 78,743 respondents in 53 countries, we examine the factors which influence respondents' answers to the question: "when jobs are scarce, should employers give priority to people of the country of origin rather than immigrants?" Taking into account a number of factors including, economic, socio-demographic, political and individual level characteristics we find that all of these factors influence respondents' preference for this form of discrimination.


N-Phenylimidazolium triflate and N-methylbenzimidazolium triflate, new imidazole-related compound/triflic acid-complex type of promoters in the phosphoramidite method, has been developed. These reagents are, particularly, useful for internucleotide-bond formation with lowly reactive reactants and have allowed an efficient, high-yield synthesis of oligodeoxyribonucleotides both in a solution phase and on a solid supports.


The article is devoted to the problem of formation of creativity of students in the process of studying the Ukrainian language and literature. The purpose of this article is based on research of Ukrainian and foreign scientists to determine the place and value of literature as an art form in the development of creative giftedness in terms of classroom and individual students' independent work. As the material for study the complex creative projects were initiated by teachers of the Ukrainian language and literature training and the research Institute of pedagogy of the University. The author cites the example of the most effective methods and forms of collaboration with gifted students (a competition of reciters of poetry, public presentation of student essays, literal works dramatisation, literal festival of the online readers). Describing the literary art work of the staff of the Department of linguamethodical and culture of professional speech, the researcher insists on the leading role of a teacher of Russian language and literature in the development of creative giftedness of future specialists, which are not just passively performs consultative and coordinating role while students work on artwork, and is also a generator of ideas, literary and linguistic authority and creative personality.
As a conclusion we would like to say that the classroom work with students has the goal to be bright, exciting resulting in creative projects. The openness of the educational environment of the University is to become a centre of science, culture and art in cities, regions, country and beyond.

The aim was to verify the effects of different anesthetic protocols used during electroejaculation (EEJ) in sixbanded armadillos (Euphractus sexcinctus). Four sexually matured animals were physically restrained and subjected to semen collection by the EEJ following three treatments: The control group consisted of no use of anesthesia; in the others, the anesthetic combinations xylazine/ketamine/propofol or butorphanol/ ketamine/propofol were administered. For each group, twelve procedures were conducted for EEJ. Semen was evaluated for volume, color, aspect, motility, sperm concentration, morphology, viability, and functional membrane integrity. The highest efficiency (100% ejaculates) was achieved when the control group was used; the xylazine/ketamine/propofol association provided only 11 ejaculates from a total of 12 attempts (91.6% efficiency), while only 4 ejaculates (33% efficiency) were obtained with butorphanol/ketamine/propofol (P<0.05). Both protocols provided rapid induction and relaxation enough to perform the EEJ. In the use of butorphanol/ketamine/propofol, the animals recovered at 16.5±1.5min, a time shorter than in the use of xylazine/ketamine/propofol protocol, 20.7±1.0min (P>0.05). The semen volume and sperm concentration obtained in the use of xylazine/ketamine/propofol association were significantly higher than those verified for butorphanol/ketamine/propofol protocol. In conclusion, the xylazine/ketamine/propofol association is indicated for anesthesia of six-banded armadillos submitted to EEJ.


The studies of QoS qualification in Ad hoc networks have focused on QoS routing algorithm presently. Artificial neural network has been an effective method for solving the large-scale optimal problems and has been proven to be able to get the exact solutions to the problem. In the paper, the minimum cost under delay constraints in Ad hoc network is studied. A new Hopfield network is proposed and the neural network could be robust to the changes of the network topology. A method about the relationships between network coefficients is proposed and it proves that the feasible solution to the problem is asymptotically stable if the network coefficients can be tuned appropriately. Finally an example is presented which proves the algorithm to be effective.


Indian sweet-Burfi is very popular khoa based confection with added sugar as well as flavoring and taste imparting ingredients which is very popular all over India. In India mostly the product is manufactured manually in open pan by manual scraping. The quality of product is not uniform due to human intervention and batch to batch variation is also there. The throughput of the product is also low as it done manually. The multipurpose scraped surface heat exchanger has been designed and developed at Dairy engineering department of SMC College of Dairy Science, AAU, Anand. The optimization of process parameters for mechanized production of burfi in the multipurpose scraped surface heat exchanger has been studied. Load size, scrapper speed and steam pressure varied in different trials. The quality of the product was analyzed in terms of sensory analysis. The steam and electrical power consumption was estimated during the manufacture of burfi. The operating conditions of the SSHE required are 2.5 kg/cm2 steam pressure, 30 rpm scraper speed and 30 kg loading. The steam and electrical power requirements for the manufacture of Burfi are 1.45 kg per kg of water evaporated and 0.12 kWh per kg of product respectively.


Since April 1999, the KLOE experiment at DAΦNE has collected about 200 pb-1 of data, produced in e+ - e- collision at the c.m. energy of 1020 MeV, the mass of the ϕ(1020) meson. This data has been used for detailed studies on the ϕ radiative decays, as well as on rare decays. The first results, based on the ~ 20 pb-1 collected in year 2000 are presented here. Perspectives for the future data taking are also discussed.


Abstract Data is being produced at an intractable pace. At the same time, there is an insatiable interest in using such data for use cases that span all imaginable domains, including health, climate, business, and gaming. Beyond the novel socio-technical challenges that surround data-driven innovations, there are still open data processing challenges that impede the usability of data-driven techniques. It is commonly acknowledged that overcoming heterogeneity of data with regard to syntax and semantics to combine various sources for a common goal is a major bottleneck. Furthermore, the quality of such data is always under question as the data science pipelines today are highly ad-hoc and without the necessary care for provenance. Finally, quality criteria that go beyond the syntactical and semantic correctness of individual values but also incorporate population-level constraints, such as equal parity and opportunity with regard to protected groups, play a more and more important role in this process. Traditional research on data integration was focused on post-merger integration of companies, where customer or product databases had to be integrated. While this is often hard enough, today the challenges aggravate because of the fact that more stakeholders are using data analytics tools to derive domain-specific insights. I call this phenomenon the democratization of data science, a process, which is both challenging and necessary. Novel systems need to be user-friendly in a way that not only trained database admins can handle them but also less computer science savvy stakeholders. Thus, our research focuses on scalable example-driven techniques for data preparation and curation. Furthermore, we believe that it is important to educate the breadth of society on implications of a data-driven world and actively promote the concept of data literacy as a fundamental competence.

The relationship between the Green function of an empty rectangular cavity with perfectly electric conducting (PEC) walls, its resonances and the eventual modal degeneracy is described. For this purpose a classification of the cavity modes according to their degeneracy will be presented first. Afterwards these modes will be identified inside the expressions of the Green functions appearing in the Mixed Potential Integral Equation (MPIE) formulation. Later these modes will be related to waveguide modes. Finally results are presented.

The safety and performance of the micra thranscatheter pacing system (MTPS) seems to be very high both in the investigational studies and in the real world setting. Much of currently available data comes from normal-sized adults, with only limited data on small-sized patients. We describe the MTPS implantation in a 71-year-old male, suffering from recurrent pacemaker infections and lead failure, who is affected by achondroplastic dwarfism with the pathognomonic phenotypical signs characterized by small size (height 120 cm; weight 39 kg), disproportionately short upper limbs, often limiting self-care skills, with an abnormal limb-to-trunk ratio. Other comorbidities include type 2 diabetes and severe thoracolumbar kyphosis. Previously, in 1970, the patient underwent a single-chamber pacemaker implantation via the right subclavian vein for complete atrioventricular block. Due to recurrent ventricular lead failure, a contralateral pacemaker implantation via the left subclavian vein was performed in


The unit commitment with transmission constraints in the alternating-current (AC) model is a challenging mixed-integer non-linear optimisation problem. We present an approach based on decomposition of a Mixed-Integer Semidefinite Programming (MISDP) problem into a mixed-integer quadratic (MIQP) master problem and a semidefinite programming (SDP) sub-problem. Between the master problem and the sub-problem, we pass novel classes of cuts. We analyse finite convergence to the optimum of the MISDP and report promising computational results on a test case from the Canary Islands, Spain.


By requiring the lower limit for the lightest right-handed neutrino mass, obtained in the baryogenesis from leptogenesis scenario, and a Dirac neutrino mass matrix similar to the up-quark mass matrix, we predict small values for the νe mass and for the matrix element mee responsible of the neutrinoless double beta decay, mνe around 5×10-3eV and mee smaller than 10-3eV, respectively. The allowed range for the mass of the heaviest right-handed neutrino is centered around the value of the scale of B–L breaking in the SO(10) gauge theory with Pati–Salam intermediate symmetry.


Many large collapses have occurred during or after underground quarry operations. The collapse of the Clamart underground quarry (in 1961, South of Paris-France) is well known as one of the most catastrophic. This paper presents a back-analysis of the case study using an empirical approach. Based on a set of assumptions, the empirical approach has indicated a reliable scenario that may explain the collapse: the large collapse may have been caused by a lack of bearing capacity of the pillars and the sudden failure of a hard limestone bed in the roof, the load on which would have been concentrated until overload occurred. The bed weakness between the two quarrying levels may also have had an influence on the general lack of stability of the quarry. Moreover, under the given hypothesis, the study shows a very low influence of the water table due to flooding of the underground quarry. rupture


Objective To evaluate the short-term effect of locally advanced NSCLC patients treated with radiotherapy and to understand its effect on alleviating radiation esophagitis and radiation pneumonitis.Methods 62 patients with locally advanced NSCLC admitted to radiotherapy department of our hospital from January 2008 to February 2010 were randomly divided into pure 3D conformal radiotherapy group(control group) and amifostine combined with 3D conformal radiotherapy group(experiment group).The experiment group was given 15 to 30 min intravenous drip of 300 mg/m2 amifostine.Six weeks after radiotherapy,the short-term effect of the two groups was assessed.During radiotherapy,the incidences of radiation esophagitis and radiation pneumonitis were recorded every week.Results A total of 44 patients completed the experiment with 23 in control group and 21 in experiment group.In the control group,1 case had complete remission and 11 cases had partial remission with an objective response rate of 52%.While in the experiment group,2 cases had complete remission and 12 cases had partial remission with an objective response rate of 67%.The objective response rate between the two groups showed no statistically significant difference(χ2=0.95,P0.05).15 cases(65%) had radiation esophagitis and 16 cases had radiation pneumonitis(70%) in the control group,while 5 cases(24%) had radiation esophagitis and 5 cases(24%) had radiation pneumonitis.The incidences of radiation esophagitis and radiation pneumonitis between the two groups showed statistically significant difference(P=0.017 and 0.003 respectively).Conclusion Amifostine can significant decrease the risk of developing serious radiation esophagitis and radiation pneumonitis without reducing response rate in NSCLC patients treated by radiotherapy.


Hydrodynamical aspects of groundwater flow in fractured formations and the basic hydraulic properties controlling the flow are the subject of the present consideration. A brief literature survey on studying the physical characteristics of the fractured rocks and on developing an understanding of the mechanism of fluid flow in fractured formations constitutes an introductory section. Basic definitions, relations, and assumptions given for subsequent interpretation of the flow behavior in a fissured rock then follow. Concepts of fractured, homogeneous, and heterogeneous water-bearing formations and their response mechanism to a pressure change are considered. The general differential equations for a flow in a fractured and in a heterogeneous formation of uniform anisotropy are derived. Two types of the flow behavior, fissure flow and pore flow, are distinguished. Two drawdown equations, respectively, for a flow in a fissure space, whether void or infilled with a fine material, and for a flow in a porous space to a well discharging at a constant rate in a fractured aquifer, are given. A fractured reservoir response to a pressure change due to pumping is illustrated by the field drawdown and recovery data. A particular case of a heterogeneous formation, an aquifer-aquitard system, is discussed, and the drawdown distribution in both aquifer and aquitard is given when account is taken of their elastic properties.


In this paper first we generalizes the Hilbert-Adjoint of a linear operator and showed that it is always closed for any linear operator with the condition that the domain of the operator is dense. We also proved that "Let J be a closed operator defined in H with dense domain then D(J*) is dense and J** = J . " We also proves Closed graph theorem for complex Hilbert spaces as a corollary of our results.


The mouse brain adapted Florio strain of Colorado tick fever virus was cultivated by yolk-sac passage in the developing chick embryo through 78 generations. The virus multiplied slowly and reached its maximal titer on the 4–5th day after inoculation.
 Experiments indicated that virus is present in significant amounts only in the central nervous system.
 The virus retained its virulence for intracerebrally inoculated mice but lost its invasive power for mice and hamsters inoculated parenterally.
 The virus introduced parenterally in minimal amounts elicited an immune response in mice which withstood subsequent intracerebral challenge with mouse brain virus.
 The 37th egg passage of the virus injected subcutaneously into four volunteers caused only minor clinical manifestations and induced the formation of homologous virus-neutralizing antibodies in all four vaccinated individuals.


This paper presents a study of the resulting overvoltages on the insulator strings of a 230 kV transmission line, taking into consideration two different models for the lightning currents: Heidler and triangular functions. The analysis was carried out considering only direct strokes to the tower and several grounding conditions. The main objective of the work is to find the front time of a triangular function that results on the same overvoltage peak produced by a Heidler function considering the same current peak. Thus, an equivalence equation between the front times is determined, providing a simplified method for the modelling and simulation of lightning currents. The main advantage of using this equivalency is the reduction of the computational efforts demanded in a series of simulations.


Fault tree analysis is NP-hard problem. In this paper, we present a method which reduces size of the fault tree by eliminating the irrelevant events. Irrelevant event is the event which has no contribution to the system failure. In a fault tree, the irrelevant events occur due to the existence of the replicated events. By investigating the structure of the replicated events we establish the conditions which characterize the irrelevant events. Based on these conditions we present the computational algorithm which eliminate the irrelevant events. Complexity of the algorithm is shown to be polynomial and so, this algorithm can be utilized efficiently in FTA.
