Burkholder integrals, Morrey's problem and quasiconformal mappings

Inspired by Morrey's Problem (on rank-one convex functionals) and the Burkholder integrals (of his martingale theory) we find that the Burkholder functionals $B_p$, $p \ge 2$, are quasiconcave, when tested on deformations of identity $f\in Id + C^\infty_0(\Omega)$ with $B_p(Df(x)) \ge 0$ pointwise, or equivalently, deformations such that $|Df|^2 \leq \frac{p}{p-2} J_f$. In particular, this holds in explicit neighbourhoods of the identity map. Among the many immediate consequences, this gives the strongest possible $L^p$- estimates for the gradient of a principal solution to the Beltrami equation $\f_{\bar{z}} = \mu(z) f_z$, for any $p$ in the critical interval $2 \leq p \leq 1+1/\|\mu_f\|_\infty$. Examples of local maxima lacking symmetry manifest the intricate nature of the problem.
MODEL-BASED NONLINEAR CONTROL OF A LOW-POWER GAS TURBINE

Abstract A simple nonlinear controller for a low-power gas turbine based on direct passivation is proposed in this paper. It uses a nonlinear state space model of the gas turbine in input-affine form based on first engineering principles. It is found by standard nonlinear analysis that the developed model is reachable and observable in the whole application domain and stable in a small neighborhood of an operating point. Accordingly, the control aim is to guarantee the asymptotic stability of every operating points in the whole application domain and to provide suitable disturbance rejection. The proposed nonlinear controller is based on a prescribed quadratic Lyapunov-function and it is able to solve the protection of the gas turbine. The robustness of the closed-loop system with respect to the time-varying parameters is also investigated.
A COMPARISON OF DISCRIMINANT ANALYSIS METHODS IN THE DIAGNOSTIC OF CORONARY HEART DISEASE

There are a large number of examples of successful applications of discriminant analysis in medical problems, especially in the field of diagnosis. In this paper a data set concerning 9 variables observed on 113 subjects (83 suffering from coronary heart disease and 30 not suffering from coronary heart disease) is analyzed. The aim of the medical study was to find a simple rule, auxiliary of the diagnosis in the out-patient clinic, able to adequately select the patients to be submitted to coronariography, an invasive test which is able to detect the disease with a high sensitivity but which is quite expensive and risky. Several linear discriminant rules are compared: Fisher's linear discriminant, logistic discriminant and a modification of Fisher's linear discriminant, recently proposed and based on the projection pursuit method. As the study involves a large number of variables, relatively to the number of observations, and since it is suspected that some of them are not very important in the detection of the disease, the problem of selecting the most important variables is also addressed. A new methodology based on backwards elimination and bootstrap tests is proposed. The results obtained were found interesting when compared to the usual procedures. The three different rules are evaluated by the probabilities (total and conditional) of correct classification estimated by three procedures: apparent, crossvalidation and bootstrap. It was possible to conclude that the second and third rules lead in this problem to satisfactory results, allowing for correct classification of about 86% of the subjects.

RECURSIVE COMPUTATION OF PARETO OPTIMAL STRATEGY FOR MULTIPARAMETER SINGULARLY PERTURBED SYSTEMS

In this paper, we study the Pareto optimal strategy for multiparameter singularly perturbed system (MSPS). In order to obtain the solution, we must solve the multiparameter algebraic Riccati equations (MARE). The main results in this paper are to propose a new recursive algorithm for solving the MARE and to find sufficient conditions regarding the convergence of our proposed algorithm. Using the recursive algorithm, we show that the solution of the MARE converges to a positive semi-definite stabilizing solution with the rate of convergence of O(||μ||i+1) under the sufficient conditions. Furthermore, we also show that the near-optimal strategy achieves the cost functional J∗ j + O(||μ||i+1).
Comparative Evaluation of Ozone Treatment in Critical Size Bone Defects Reconstructed with Alloplastic Bone Grafts

The purpose of this study was to investigate osteogenesis promoted by osteoconductive properties of bone grafting materials and the histopathological effects of ozone on osteogenesis. In total, 56 Winstar rats were equally divided into 4 groups. In control group, calvarial bone defect was created in 14 rats. For second group, 8 mm calvarial bone defect with ozone treatment was applied in 14 rats. For third group, an alloplastic bone graft was implanted on 8 mm calvarial bone defect. In fourth group, alloplastic bone graft was inserted in calvarial defect and ozone was treated additionally. Seven of the rats were sacrificed at the end of 4th week and the remaining 7 were sacrificed at the end of 8th week of experiment. In the study, the periosteal flaps were removed with a thin periosteal elevator and averagely 0.8 cm diameter-circular full bone defect was created with a specially designed trephine drill. The bone from the calvarial region was fixed in 10% formalin solution. After decalcification, bones were taken for routine paraffin blocking. Sections were stained with Hematoxylin-Eosin and Masson Trichrome. Histopathological findings of 4th and 8th weeks rats showed that best result for new bone formation was observed in graft + ozone treatment. It is concluded that ozone treatment increases the hemostasis in graft region, induces angiogenesis, promotes cell proliferation by preventing infiltration, induces matrix formation by influencing osteoblastic activity and has a positive effect in osteogenesis.

Running Head: READING WORDS AND PEOPLE IN SEMANTIC VARIANT PPA Reading words and other people: a comparison of exception word, familiar face and affect processing in the left and right temporal variants of primary progressive aphasia

Semantic variant primary progressive aphasia (svPPA) typically presents with left-hemisphere predominant rostral temporal lobe atrophy and the most significant complaints within the language domain. Less frequently, patients present with right-hemisphere predominant temporal atrophy coupled with marked impairments in processing of famous faces and emotions. Few studies have objectively compared these patient groups in both domains and therefore it is unclear to what extent the syndromes overlap. Clinically diagnosed svPPA patients were characterized as left(n= 21) or right-predominant (n = 12) using imaging and compared along with 14 healthy controls. Regarding language, our primary focus was upon two hallmark features of svPPA; confrontation naming and surface dyslexia. Both groups exhibited naming deficits and surface dyslexia although the impairments were more severe in the left-predominant group. Familiarity judgments on famous faces and affect processing were more profoundly impaired in the right-predominant group. Our findings suggest that the two syndromes overlap significantly but that early cases at the tail ends of the continuum constitute a challenge for current clinical criteria. Correlational neuroimaging analyses implicated a mid portion of the left lateral temporal lobe in exception word reading impairments in line with proposals that this region is an interface between phonology and semantic knowledge.
DEFLECTIONS OF FAST CORONAL MASS EJECTIONS AND THE PROPERTIES OF ASSOCIATED SOLAR ENERGETIC PARTICLE EVENTS

The onset times and peak intensities of solar energetic particle (SEP) events at Earth have long been thought to be influenced by the open magnetic fields of coronal holes (CHs). The original idea was that a CH lying between the solar SEP source region and the magnetic footpoint of the 1 AU observer would result in a delay in onset and/or a decrease in the peak intensity of that SEP event. Recently, Gopalswamy et al. showed that CHs near coronal mass ejection (CME) source regions can deflect fast CMEs from their expected trajectories in space, explaining the appearance of driverless shocks at 1 AU from CMEs ejected near solar central meridian (CM). This suggests that SEP events originating in CME-driven shocks may show variations attributable to CH deflections of the CME trajectories. Here, we use a CH magnetic force parameter to examine possible effects of CHs on the timing and intensities of 41 observed gradual E ∼ 20 MeV SEP events with CME source regions within 20° of CM. We find no systematic CH effects on SEP event intensity profiles. Furthermore, we find no correlation between the CME leading-edge measured position angles and SEP event properties, suggesting that the widths of CME-driven shock sources of the SEPs are much larger than the CMEs. Independently of the SEP event properties, we do find evidence for significant CME deflections by CH fields in these events.
Title: THE GENETIC REQUIREMENTS FOR FAST AND SLOW GROWTH IN MYCOBACTERIA Running head. Mycobacterial genes required for growth rate control Authors and Affiliations

Mycobacterium tuberculosis infects a third of the world’s population. Primary tuberculosis involving active fast bacterial replication is often followed by asymptomatic latent tuberculosis, which is characterised by slow or non-replicating bacteria. Reactivation of the latent infection involving a switch back to active bacterial replication can lead to post-primary transmissible tuberculosis. Mycobacterial mechanisms involved in slow growth or switching growth rate provide rational targets for the development of new drugs against persistent mycobacterial
Violence against Preparatory School Teachers at Cairo Governorate

violence against teachers is a universal problem of the 21st century. Higher rates of violence directed toward teachers were associated with disorganized school structures, negative school climates, lack of administrative and collegial social supports, and high residential crowding. Aim: to assess frequency and causes of school violence against school teachers and develop a guideline to prevent school violence against teachers. Design: a descriptive correlational research design was utilized. Setting: data were collected from preparatory schools for boys at EL-Sayeda Zeinab educational directorate. Sample: a convenient sample of all teachers in preparatory schools for boys at EL-Sayeda Zeinab educational directorate who exposed to violence was included in the study. Tool for data collection: one tool was used in this study; School teacher structured interviewing Sheet that has two parts: 1) teacher’s personal and work data: age, sex, educational level, job category and duration of work. 2) Violence data: types of violence, source of violence, frequency of exposure to violence and occurrence of injury, causes of school violence and work environment. Results: study results revealed that, 76.3% of the teachers were males, their mean age was 39.79 ± 6.9 year and all the teachers were married. Regarding mean work duration it was 13.92 ± 6.97 year. Results revealed that, 52.6% of teachers were exposed to verbal violence and 38.2% of them were exposed to both physical and verbal violence. In relation to the frequency of violence, 67.1% of teachers were exposed to violence less than five times while 32.9 % reported exposure to violence five times. Regarding the sources of violence, 64.9% of the teachers were exposed to violent acts by students and 19.7% of them were exposed to violence from student’s parents. Only 13.6% of teachers reported exposure to physical injury and 33.8% officially reported after exposure to violence. As for the causes of violence results revealed that, 87.3% of the students developed a violent behavior probably as a result of overcrowded classes, 95.2% as a result of large family size and 82% absence of trained security person in the schools. Conclusion: the common causes of violence were; overcrowded classes, large family size, and absence of trained security person. Recommendations: based on the study results the following recommendations were suggested; this study should be carried out on a large sample of teachers and student’s perspectives on violence against teachers.
Robot Control near Singularity and Joint Limit Using a Continuous Task Transition Algorithm

When robots are controlled in the task space, singularities and joint limits are among the most critical and difficult issues that can arise. In this paper, we propose a new approach for the robots to operate in the regions near singularities and joint limits using the operational space control framework. Specifically, a continuous task transition algorithm called the intermediate desired value approach is applied to the hierarchically structured controller in the operational space control framework. In this approach, new tasks are defined for dealing with singularities and joint limits, and the tasks are activated or deactivated using the continuous task transition algorithm to guarantee the continuous execution of the tasks during the execution of the main task. The proposed approach is implemented on a 6-DOF manipulator called Roman-MD. The experimental results demonstrate its performance near the singular regions and joint limits.
Geography, Joint Choices, and the Reproduction of Gender Inequality

We examine the extent to which the gender wage gap stems from dual-earner couples jointly choosing where to live. If couples locate in places better suited for the man’s employment than for the woman’s, the resulting mismatch of women to employers will depress women’s wages. Examining data from Denmark, our analyses indicate that (1) Danish couples choose locations with higher expected wages for the man than for the woman, (2) the better matching of men in couples to local employers could account for up to 36 percent of the gender wage gap, and (3) the greatest asymmetry in the apparent importance of the man’s versus the woman’s potential earnings occurred among couples with young children and where the male partner accounted for a larger share of household income before the potential move.
Optical tweezers and confocal microscopy for simultaneous three-dimensional manipulation and imaging in concentrated colloidal dispersions

A setup is described for simultaneous three-dimensional manipulation and imaging inside a concentrated colloidal dispersion using (time-shared) optical tweezers and confocal microscopy. The use of two microscope objectives, one above and one below the sample, enables imaging to be completely decoupled from trapping. The instrument can be used in different trapping (inverted, upright, and counterpropagating) and imaging modes. Optical tweezers arrays, dynamically changeable and capable of trapping several hundreds of micrometer-sized particles, were created using acousto-optic deflectors. Several schemes are demonstrated to trap three-dimensional colloidal structures with optical tweezers. One combined a Pockels cell and polarizing beam splitters to create two trapping planes at different depths in the sample, in which the optical traps could be manipulated independently. Optical tweezers were used to manipulate collections of particles inside concentrated colloidal dispersions, allowing control over collo.
ON BUOYANCY , TURBULENCE AND COMBUSTION IN FIRE FIELD MODELLING

Buoyancy, turbulence and combustion in simulating a compartment fire with a field model (or application of Computational Fluid Dynamics) are discussed. The ISO room-corner fire test is taken as an example. Flaming region of the fire is taken as a combustion gas volume region with reacting and not yet reacting zones. Those zones might be in laminar flow or in turbulent flow, depending on their positions and mixing ratios of fuel and air. A model based on eddy dissipation concept which can simulate premixed, partially premixed and nonpremixed combustion with buoyancy was used together with k-ε type of turbulence model with buoyancy.
Phenolic Compounds and Antioxidant Activities of Pomegranate Peels

Methanol and aqueous extracts of pomegranate peels (Punica granatum L.) from two Egyptian varieties (Wardey and Manfalouty) were screened for phenolic compounds and antioxidant activities. Amounts of phenolic compounds in methanol peels extracts were higher than those in water extracts. The relative contents of phenolic compounds displayed variability as Manfalouty contained higher percent of phenolic compounds for protocatchoic acid, P-cumaric acid, chlorogenic acid, catechin, epicatechin, ellagic acid. However, Wardey peel contained higher percentage of phenolic compounds for vanillic acid, Caffeic acid and ferulic acid. Antioxidant activities of peel extracts by β-carotene-linoleate model system showed that inhibition values of methanol both peel extracts exhibited higher values than water extracts. 
Adaptive abilities of the females and sustainability of ruminant livestock systems. A review

In a systemic approach, the breeder can be considered as the decisional component of the livestock system, whereas animals are usually depicted to be part of its biotechnical compo- nent. The animal itself is a biological system whose ability to survive, grow, reproduce and cope with the environnement and livestock practices play a major role in the ability of the livestock sys- tem to sustain. In such a conceptual representation of the system, the reproductive females draw a peculiar attention since they determine in a great part the productivity and the durability of the system through their abilities to maintain their own production level (milk production, numeric productivity) and to save their reproductive efficiency (repeated pregnancies and lactations) over years. Considering the animal level and its lifespan, it is clear that the abilities to adapt rely on be- havioural and physiological regulatory processes. The study of the biological mechanisms involved in the adaptation to undernutrition is particularly interesting since regulatory processes implied in energy metabolism may interfere directly or indirectly with the reproductive function, and conse- quently, with the durability of the livestock system. A biological significance of such relationships between nutrition and reproduction is given that they allow the female to be informed about the associated risk of entering a productive process facing the uncertainty of the nutritional context. Although the general mechanisms implied in the ability to adapt to the underfeeding constraint are conserved among ruminants, the thresholds (or priorities) may largely differ according to the breed within the same species. Hence, in order to evaluate the ability of the ruminant livestock systems to perpetuate in hard environments (maintaining their production levels) or to assess sustainable objectives (opening bushy landscapes by increasing grazing pressure), animals' inherent adaptive potentialities have to be well known.
Assessment of Cardiac Autonomic Function by Using Heart Rate Turbulence in Behcet's Disease

Behcet’s disease (BD) is a chronic inflammatory disorder that can affect many systems in the body. Cardiac involvement increases the risk of cardiovascular mortality and occurs in 1%-5% of patients with BD. Ventricular arrythmias are believed to be the cause of this increased risk of cardiovascular mortality and it is also thought to be related with cardiac autonomic dysfunction. Heart rate turbulence (HRT) is a new predictor of cardiac autonomic activity. HRT is an independent and powerful predictor of mortality. In this study, we investigated the cardiac autonomic activity which can be determined by HRT in patients with BD. Forty patients with BD (20 men, mean age: 40 ± 9 years, range: 27-55 years) were diagnosed according to the International Study Group Criteria (ISGC) and gender and age matched healthy volunteers (20 men, mean age: 39 ± 8 years, range: 26-56 years) were included in this study. All of the participants (patients and controls) underwent 24 hours Holter electrocardiogram. HRT parameters, turbulence onset (TO) and turbulence slope (TS) were calculated with HRT (View Version 0.60-0.1 of Software Program). There were no significant differences in TO and TS values between patients with BD and control subject (TO-BD: 0.014 ± 0.03, TO-Control: 0.011 ± 0.04; TS-BD: 7.88 ± 4.9, TS-Control: 9.42 ± 6.7 respectively). Although increased cardiovascular mortality rates in BD have been shown in many studies, HRT values—detecting the risk of sudden death—do not seem to be altered in this disease.
Impact of Lactic acid bacteria ( LAB ) as probiotic against bacterial pathogen from Cyprinus carpio

The aim of the present study is to investigate the potential of lactic acid bacteria as a probiotic (biologicl dieases control). Six strains of lactic acid bacteria J1, J3, J4, J6, J7, J8 was Isolated from intestines of the common carp Cyprinus carpio were compared as to the antagonistic activity against fish pathogen bacteria Aeromonas hydrophila, Pseudomonas luteola Pseudomonas aeroginosa Sarratia rabidaeae and staph sp. Different method were used for measuring growth by optical density, agar well diffusion and crossstreak method also screened from bile salt and antibiotic tolerance. All strains of LAB showed different spectra of inhibition against pathogenic bacteria. The highest inhibition measured against serratia rubidaeae and A. hydrophila, moderate inhibition occure against. P. luteola and P aeroginosa and lower inhibition to staph sp. Also culture supernatant free fluid of all LAB showed no antagonistic activity against pathogenic bacteria moreover all strain show resistance to all antibiotic sensitivity OA2A–P disc except J1, J3, J4 were sensitive to erythromycin in concentrate 60 mcg after incubation for 48 hr and only J1, J3, J4, J6 were exhibited tolerance reaction to bile salt at concentration not more than 3000 ppm the present study recommend to use lactic acid bacteria J6 as a good probiotic remedy to the fish culture in Iraq. ريثأت ايرتكب ضماح كيتكلالا LAB تاززعمك ةيويح دض يرتكبلا ا ةيضرملا يف
The Cost Minimization Model in Warehouse Distribution System

In today’s world, warehousing and distribution centres play a vital role to fulfil customer demand and requirement. Firms cannot ignore the importance of warehouse and distribution centres. In addition, firms are using DCs (distribution centres) and warehouses for valuation addition purposes such as, postponement strategies, break-bulking, consolidation, and packing and packaging etc. This research aim is to develop a model to reduce warehouse cost and increase or improved customer service. The results and discussions with personnel’s of distribution department seem to offer a lesson. It is that, though human distribution “optimizers” out of necessity, must concentrate their efforts on maintaining the most economical primary shipment transportation system, a mechanical “optimizer” like as MODS (model of optimizing distribution centres) is able to find out and determine the most economical system from the standpoint of whole the relevant costs to be considered.
