kardiomiopatije (DCM) u bolesnika s dijabetesom tipa 2. Metode: U istraživanje je bilo uključeno dvjesto ispitanika s dijabetesom tipa 2 (DM). Isključeni su ispitanici s koronar nom bolesti srca (CAD), valvularnom bolesti srca ili anamnestičkim podatcima o zlouporabi droga ili alkohola. Nakon anamnestičkih podataka utvrđeni su indeks tjelesne mase, učestalost pušenja, dislipidemije, DMa, uporaba lijekova te su provedeni procjena dijagnostičkih kriterija zatajivanja srca (HF) prema Framinghamskoj studiji, klinički pregled, 12kanalni elektrokardiogram u mirovanju, transtorakalna ehokardiografija te jedna od laboratorijskih varijabli: HbA1c, nasumične ili natašte izmjerene vrijednost glukoze u krvi ili rezultat dvosatnog testa oralne podnošljivosti glukoze. Rezultati: Prevalencija u usporedbi s odsutnošću DCMa, dijastolička disfunkcija lijeve klijetke (LV) II. i III. stupnja, sistolička disfunkcija i hipertrofija u istraživanoj skupini iznosile su, redom: 23,0 % prema 77,0 %, 18,5 %, 5,0 % i 8,0 %. U skupini s DCM om postojala je značajna razlika u učestalosti dijastoličke disfunkcije LVa II. i III. stupnja, sistoličke disfunkcije i hipertrofiji u usporedi sa skupinom ispitanika bez DCMa, s apsolutnim povećanjem rizika u skupini s DCMom za ta stanja od, redom, 80 %, 22 % i 35 %. Pronađena je i signifikantna razlika u prosječnoj vrijednosti ejekcijske frakcije (EF) između skupina s DCMom i bez DCMa. Prosječna EF u skupini s DCMom bila je za 5,5 % niža nego u skupini bez DCMa. Zastupljenost HFa i pretkliničke HF u skupini s DCMom iznosila je 65 % i 35 %. U skupni s DCMom prosječna je dob kod HFa bila 4,1 godinu viša nego prosječna dob za pretklinički HF. Pušenje je bilo izrazito i značajno povezano s HFom u odnosu prema predkliničkom HFu u skupni s DCMom. Zaključci: DCM je bio zastupljen u egipatskih bolesnika s dijabetesom tipa 2 te se može smatrati primarnom miokardijalnom bolešću koja uzrokuje predispoziciju za HF kod dijabetesa tipa 2. SUMMARY: Objective: A multicenter study to evaluate the prevalence and cardiovascular outcomes of diabetic cardiomyo pathy in type II diabetic patients. Patients and Methods: Two hundred participants with type II diabetes mellitus (DM) were included, while participants with coronary artery disease (CAD), valvular heart disease, or history of alcohol or drug abuse were excluded. Participants were subjected to history taking for age, gender, body mass index, smoking, dyslipidemia, medications, DM, Framingham diag nostic criteria of heart failure (HF), comprehensive clinical examination, 12 leads resting electrocardiogram, transthoracic echocardiography and one of the following laboratory investigations: glycated hemoglobin, random blood sugar, fasting blood sugar, or 2hour 75gram oral glucose tolerance test. Results: The prevalence of diabetic cardiomyopathy versus (vs) no diabetic cardiomyopathy, left ventricular (LV) diastolic dysfunction grade II and III, systolic dysfunction, and hypertrophy in the study population was 23.0% vs 77.0%, 18.5%, 5.0%, and 8.0%, respectively. There was a highly significant difference between LV diastolic dysfunction grade II and III, systolic dysfunction, and hypertrophy in the diabetic cardiomyopathy group vs no diabetic cardiomyopathy group, with an absolute risk increase of 80%, 22%, and 35% in the diabetic cardiomyopathy group, respectively. There was a highly significant differ ence between the mean ejection fraction (EF) in the diabetic cardiomyopathy group vs the no diabetic cardiomyopathy group. The mean EF for the diabetic cardiomyopathy group was 5.5% lower than the mean EF for the no diabetic cardiomyopathy group. The prevalence of HF and preclinical HF in the diabetic cardiomyopathy group was 65% and 35%, respectively. The mean age for HF was 4.1 years older than the mean age for preclinical HF in the diabetic cardiomyopathy group. Smoking was significantly and strongly associated with HF vs preclinical HF in the diabetic cardiomyopathy group. Conclusions: Diabetic cardiomyopathy was prevalent in an Egyptian type II diabetic patient population and could be consid ered a primary myocardial disease predisposing to HF in type II DM.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="a81c2470681e2df499f4e23def1aa4d0" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476695,"asset_id":87198029,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476695/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198029"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198029"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198029;

The hydroalcoholic extract was subjected to preliminary phytochemical analysis. Then Fractionation using chloroform, ethyl acetate, and n. butanol. The ethyl acetate and n. butanol fractions were separately reflexed with 5% HCl for several hours. Fractions (ethyl acetate and n. butanol) before and after hydrolysis were examined by HPTLC (high performance thin-layer chromatography) for their flavonoids and phenolic acids contents. Anthraquinon, cardiac glycosides, alkaloid and steroids were not detected in crude extract. Flavonoids and phenolic acids were detected in analyzed fractions. Quercetrin and rutin respectively were the main identified flavonoids in ethyl acetate and n. butanol fractions before hydrolysis; quercetin was the main detected aglycone in acidic hydrolyzed fractions.

In the two scenarios, the spiral collector were fabricated from copper tube with 10 mm inner diameter, 15 m length and absorber area 0.5 m2. The lens was selected as acrylic flat lens with transmittance (80 to 90)% and focal distance is 1.3 m. Experiments were carried out at water mass flow rate 0.5 kg/min under the period between 1st to 31th of December over the ambient temperature range of 12 to 17 ℃ and hourly solar radiation range of 525 to 654 W/m2. The experimental results show that the maximum outlet-temperature, useful energy and efficiency was found to be about 19 ℃, 109 W, 35% respectively in scenario of spiral collector without lens. While, in the scenario of spiral with lens was found to be about 21 ℃, 178 W, 60% respectively. As compared between the two scenario, the lens was enhanced the efficiency of spiral collector by 25%.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198023"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198023"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198023; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87198023]").text(description); $(".js-view-count[data-work-id=87198023]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87198023; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87198023']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=87198023]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87198023,"title":"Case study on spiral solar collector performance with lens","internal_url":"https://www.academia.edu/87198023/Case_study_on_spiral_solar_collector_performance_with_lens","owner_id":221739944,"coauthors_can_edit":true,"owner":{"id":221739944,"first_name":"Marwa","middle_initials":null,"last_name":"Mohammad","page_name":"MarwaMohammad27","domain_name":"independent","created_at":"2022-04-24T09:48:38.770-07:00","display_name":"Marwa Mohammad","url":"https://independent.academia.edu/MarwaMohammad27"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="87198021"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/87198021/Alterations_of_Static_and_Dynamic_Balance_in_Lumbar_Radiculopathy"><img alt="Research paper thumbnail of Alterations of Static and Dynamic Balance in Lumbar Radiculopathy" class="work-thumbnail" src="https://attachments.academia-assets.com/91476640/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/87198021/Alterations_of_Static_and_Dynamic_Balance_in_Lumbar_Radiculopathy">Alterations of Static and Dynamic Balance in Lumbar Radiculopathy</a></div><div class="wp-workCard_item"><span>The Medical Journal of Cairo University</span><span>, 2018</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Background: Lumbar radiculopathy is a benign, often self-limiting condition.

It is characterized by low back pain radiating into one or both lower limbs, combined with one or more positive neurological signs (paresis, sensory impairment, or loss of reflexes) that indicate a nerve root irritation or neurological loss of function. This can be due to mechanical compression of the nerve by a disc herniation which may lead to balance disorders in standing position and to asymmetrical load of lower extremities results from pain radiating to lower extremities and leads to distorted postural stability, as well as to other motor deficits. The consequences are disability, reduced quality of health and reduced working capability. Aim of Study: The purpose of this study was to investigate the alterations of static and dynamic balance in patients with lumbar radiculopathy. Patients and Methods: Twelve patients, both genders with unilateral lumbar radiculopathy were included in the study with a mean age 47.25 (±5.61) years. They were assessed for impairments in static and dynamic balance, compared with twelve normal/healthy subjects. functional reach test" FRT" was used to test static balance by measuring (MAD) maximum anterior reaching distance measured in cm. and Biodex Balance System (BBS) was used to measure dynamic balance. The evaluation of dynamic balance included both Dynamic Balance Test (DBT) and the Dynamic Limits of Stability (DLOS). The (DBT) include the anterior/posterior stability index (APSI), the Medial/Lateral Stability Index (MLSI) and the Overall Stability Index (OASI). The DLOS parameters were expressed as overall Direction Control (DC) and time required for completing the test (T). Results: There was statistically significant differences in all measured variables of static and dynamic balance; between lumbar radiculopathy (A) and control group (B). There was a significant reduction of the mean values of OASI, APSI with (p>0.0001*), T with (p=0.0001*) and MLSI with (p>0.002*) in group (B) and significant increase of the mean values of F.R.T. in group (B). While, there was a significant increase of the mean values of D.C. with (p=0.0001 *) in group (B).</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="1b7c2132d00bf2c4373f709c7ef4494b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476640,"asset_id":87198021,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476640/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198021"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198021"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198021;

The proposed electrodes have Nernstian slope values of 59.200.52±, 58.000.22± and 58.520.22± mV decade-1 for electrodes modified with 7.5, 17.5 and 7.5 mg of RN (electrode I), NaTPB (electrode II) and PTA (electrode III) ion pairing agents, respectively. It is found that the dynamic drug concentration range at 25 °C was 1.0x10-5-1.0x10-2 mole L-1 with detection limit (LOD) equal 1.0× 10-5 mol L-1 and limit of quantification (LOQ) equal 3.33×10-5 mol L-1. The response of MSPEs was pH independent in the range 2.0-6.0. The investigated electrodes have fast response time of 10, 9 and 8 s for electrodes I, II and III, respectively. These electrodes have good Nernstian response in the temperature range 10-60 °C. The slope of the straight-line obtained represented the isothermal coefficient of MSPEs which were found to be 1.594 ×10-3 , 2.151×10-3 and 2.377×10-3 V/ for electrodes I, II and III, respectively. The small values of the isothermal coefficient indicated the high thermal stability of the electrodes. The MSPEs showed a relatively long life time of 36 days. Pure, biological fluids and pharmaceutical formulation of OBCH were quantified using calibration and standard addition methods and the obtained results agreed with that of the official HPLC method. Validation parameters were optimized according to ICH recommendations.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2f857bdb5788df0f1c3af324561cda7d" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476643,"asset_id":87198019,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476643/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198019"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198019"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198019;

The oxidative damage of both liver and kidney was assessed by serum alkaline phosphatase (ALP), Gamma Glutamyl Trans-Peptidase (GGTP), Alanine and Aspartate Amino Transferase (ALT & AST) activities in addition concentrations of cholesterol, high density lipoprotein-cholesterol (HDL-c), low density lipoprotein-cholesterol (LDL-c), Triacyglycerols (TGs), urea and creatinine were analyzed. Liver lipid peroxidation (MDA), Nitric Oxide (NO), reduced glutathione (GSH) levels, and activities of both Super-Oxide Dismutase (SOD) and Glutathione Peroxidase (GSH-Px) were measured. Results: TCE administration increase serum ALP, GGTP, ALT, AST activities, cholesterol, triacylglycerols, LDL-c, urea and creatinine concentrations, besides liver MDA and NO, whereas it decreased SOD, GSH-Px activities, GSH level in liver, HDL-c in serum. Low dose of gamma rays (0.5 Gy) exposure significantly improved lipid peroxidation and oxidative injury induced by TCE. Conclusion: The study indicates that treatment with low dose of gamma rays ameliorate harmful effects induced by TCE taking in consideration the effect of gamma radiation as a stimulant of radical detoxification.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="72c1506300b1c4e2fa76703bdaf93c7b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476696,"asset_id":87198014,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476696/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198014"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198014"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198014;

This high level of usage requires autonomy in the system, which mainly corresponds to constraint satisfaction in the context of users' submissions. In other words, in case that the users' inputs to the robots may lead to collisions, these inputs must be altered to avoid these collisions automatically. However, these alterations must be minimal so as to preserve the users' objective in the experiment. Toward this end, the system has utilized barrier functions, which admit a minimally invasive controller-synthesis procedure. However, barrier functions are yet to be robustified with respect to unmodeled disturbances (e.g., wheel slip or packet loss) in a manner conducive to realtime synthesis. As such, this paper formulates robust barrier functions for a general class of disturbed control-affine systems that, in turn, is key for the Robotarium to operate fully autonomously (i.e., without human supervision). Experimental results showcase the effectiveness of this robust formulation in a long-term experiment in the Robotarium.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="24f40c94dfe696f0d4965799de456911" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84821903,"asset_id":77468379,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84821903/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468379"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468379"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468379;

To operate effectively under these changing conditions, algorithms developed for long-term autonomy applications require a stronger focus on robustness. Consequently, this work considers the ability to satisfy the operation-critical constraints of a disturbed system in a modular fashion, which means compatibility with different system objectives and disturbance representations. Toward this end, this paper introduces a controller-synthesis approach to constraint satisfaction for disturbed control-affine dynamical systems by utilizing Control Barrier Functions (CBFs). The aforementioned framework is constructed by modelling the disturbance as a union of convex hulls and leveraging previous work on CBFs for differential inclusions. This method of disturbance modeling grants compatibility with different disturbance-estimation methods. For example, this work demonstrates how a disturbance learned via a Gaussian process may be utilized in the proposed framework. These estimated disturbances are incorporated into the proposed controller-synthesis framework which is then tested on a fleet of robots in different scenarios.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="17a7e5c6d485332517cead20468b8a72" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84821901,"asset_id":77468378,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84821901/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468378"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468378"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468378;

However, it typically requires the exploration of a sufficiently large number of state-action pairs, some of which may be unsafe. Consequently, its application to safety-critical systems remains a challenge. Towards this end, an increasingly common approach to address safety involves the addition of a safety layer that projects the RL actions onto a safe set of actions. In turn, a challenge for such frameworks is how to effectively couple RL with the safety layer to improve the learning performance. In the context of leveraging control barrier functions for safe RL training, prior work focuses on a restricted class of barrier functions and utilizes an auxiliary neural net to account for the effects of the safety layer which inherently results in an approximation. In this paper, we frame safety as a differentiable robust-control-barrier-function layer in a model-based RL framework. As such, this approach both ensures safety ...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="bf3267cc7cbf2d1851b7363a1b0f8a5e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84800137,"asset_id":77468375,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84800137/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468375"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468375"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468375;

Nakon anamnestičkih podataka utvrđeni su indeks tjelesne mase, učestalost pušenja, dislipidemije, DMa, uporaba lijekova te su provedeni procjena dijagnostičkih kriterija zatajivanja srca (HF) prema Framinghamskoj studiji, klinički pregled, 12kanalni elektrokardiogram u mirovanju, transtorakalna ehokardiografija te jedna od laboratorijskih varijabli: HbA1c, nasumične ili natašte izmjerene vrijednost glukoze u krvi ili rezultat dvosatnog testa oralne podnošljivosti glukoze. Rezultati: Prevalencija u usporedbi s odsutnošću DCMa, dijastolička disfunkcija lijeve klijetke (LV) II. i III. stupnja, sistolička disfunkcija i hipertrofija u istraživanoj skupini iznosile su, redom: 23,0 % prema 77,0 %, 18,5 %, 5,0 % i 8,0 %. U skupini s DCM om postojala je značajna razlika u učestalosti dijastoličke disfunkcije LVa II. i III. stupnja, sistoličke disfunkcije i hipertrofiji u usporedi sa skupinom ispitanika bez DCMa, s apsolutnim povećanjem rizika u skupini s DCMom za ta stanja od, redom, 80 %, 22 % i 35 %. Pronađena je i signifikantna razlika u prosječnoj vrijednosti ejekcijske frakcije (EF) između skupina s DCMom i bez DCMa. Prosječna EF u skupini s DCMom bila je za 5,5 % niža nego u skupini bez DCMa. Zastupljenost HFa i pretkliničke HF u skupini s DCMom iznosila je 65 % i 35 %. U skupni s DCMom prosječna je dob kod HFa bila 4,1 godinu viša nego prosječna dob za pretklinički HF. Pušenje je bilo izrazito i značajno povezano s HFom u odnosu prema predkliničkom HFu u skupni s DCMom. Zaključci: DCM je bio zastupljen u egipatskih bolesnika s dijabetesom tipa 2 te se može smatrati primarnom miokardijalnom bolešću koja uzrokuje predispoziciju za HF kod dijabetesa tipa 2. SUMMARY: Objective: A multicenter study to evaluate the prevalence and cardiovascular outcomes of diabetic cardiomyo pathy in type II diabetic patients. Patients and Methods: Two hundred participants with type II diabetes mellitus (DM) were included, while participants with coronary artery disease (CAD), valvular heart disease, or history of alcohol or drug abuse were excluded. Participants were subjected to history taking for age, gender, body mass index, smoking, dyslipidemia, medications, DM, Framingham diag nostic criteria of heart failure (HF), comprehensive clinical examination, 12 leads resting electrocardiogram, transthoracic echocardiography and one of the following laboratory investigations: glycated hemoglobin, random blood sugar, fasting blood sugar, or 2hour 75gram oral glucose tolerance test. Results: The prevalence of diabetic cardiomyopathy versus (vs) no diabetic cardiomyopathy, left ventricular (LV) diastolic dysfunction grade II and III, systolic dysfunction, and hypertrophy in the study population was 23.0% vs 77.0%, 18.5%, 5.0%, and 8.0%, respectively. There was a highly significant difference between LV diastolic dysfunction grade II and III, systolic dysfunction, and hypertrophy in the diabetic cardiomyopathy group vs no diabetic cardiomyopathy group, with an absolute risk increase of 80%, 22%, and 35% in the diabetic cardiomyopathy group, respectively. There was a highly significant differ ence between the mean ejection fraction (EF) in the diabetic cardiomyopathy group vs the no diabetic cardiomyopathy group. The mean EF for the diabetic cardiomyopathy group was 5.5% lower than the mean EF for the no diabetic cardiomyopathy group. The prevalence of HF and preclinical HF in the diabetic cardiomyopathy group was 65% and 35%, respectively. The mean age for HF was 4.1 years older than the mean age for preclinical HF in the diabetic cardiomyopathy group. Smoking was significantly and strongly associated with HF vs preclinical HF in the diabetic cardiomyopathy group. Conclusions: Diabetic cardiomyopathy was prevalent in an Egyptian type II diabetic patient population and could be consid ered a primary myocardial disease predisposing to HF in type II DM.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="a81c2470681e2df499f4e23def1aa4d0" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476695,"asset_id":87198029,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476695/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198029"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198029"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198029;

In the two scenarios, the spiral collector were fabricated from copper tube with 10 mm inner diameter, 15 m length and absorber area 0.5 m2. The lens was selected as acrylic flat lens with transmittance (80 to 90)% and focal distance is 1.3 m. Experiments were carried out at water mass flow rate 0.5 kg/min under the period between 1st to 31th of December over the ambient temperature range of 12 to 17 ℃ and hourly solar radiation range of 525 to 654 W/m2. The experimental results show that the maximum outlet-temperature, useful energy and efficiency was found to be about 19 ℃, 109 W, 35% respectively in scenario of spiral collector without lens. While, in the scenario of spiral with lens was found to be about 21 ℃, 178 W, 60% respectively. As compared between the two scenario, the lens was enhanced the efficiency of spiral collector by 25%.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198023"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198023"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198023; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87198023]").text(description); $(".js-view-count[data-work-id=87198023]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87198023; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87198023']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=87198023]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87198023,"title":"Case study on spiral solar collector performance with lens","internal_url":"https://www.academia.edu/87198023/Case_study_on_spiral_solar_collector_performance_with_lens","owner_id":221739944,"coauthors_can_edit":true,"owner":{"id":221739944,"first_name":"Marwa","middle_initials":null,"last_name":"Mohammad","page_name":"MarwaMohammad27","domain_name":"independent","created_at":"2022-04-24T09:48:38.770-07:00","display_name":"Marwa Mohammad","url":"https://independent.academia.edu/MarwaMohammad27"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="87198021"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/87198021/Alterations_of_Static_and_Dynamic_Balance_in_Lumbar_Radiculopathy"><img alt="Research paper thumbnail of Alterations of Static and Dynamic Balance in Lumbar Radiculopathy" class="work-thumbnail" src="https://attachments.academia-assets.com/91476640/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/87198021/Alterations_of_Static_and_Dynamic_Balance_in_Lumbar_Radiculopathy">Alterations of Static and Dynamic Balance in Lumbar Radiculopathy</a></div><div class="wp-workCard_item"><span>The Medical Journal of Cairo University</span><span>, 2018</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Background: Lumbar radiculopathy is a benign, often self-limiting condition.

It is characterized by low back pain radiating into one or both lower limbs, combined with one or more positive neurological signs (paresis, sensory impairment, or loss of reflexes) that indicate a nerve root irritation or neurological loss of function. This can be due to mechanical compression of the nerve by a disc herniation which may lead to balance disorders in standing position and to asymmetrical load of lower extremities results from pain radiating to lower extremities and leads to distorted postural stability, as well as to other motor deficits. The consequences are disability, reduced quality of health and reduced working capability. Aim of Study: The purpose of this study was to investigate the alterations of static and dynamic balance in patients with lumbar radiculopathy. Patients and Methods: Twelve patients, both genders with unilateral lumbar radiculopathy were included in the study with a mean age 47.25 (±5.61) years. They were assessed for impairments in static and dynamic balance, compared with twelve normal/healthy subjects. functional reach test" FRT" was used to test static balance by measuring (MAD) maximum anterior reaching distance measured in cm. and Biodex Balance System (BBS) was used to measure dynamic balance. The evaluation of dynamic balance included both Dynamic Balance Test (DBT) and the Dynamic Limits of Stability (DLOS). The (DBT) include the anterior/posterior stability index (APSI), the Medial/Lateral Stability Index (MLSI) and the Overall Stability Index (OASI). The DLOS parameters were expressed as overall Direction Control (DC) and time required for completing the test (T). Results: There was statistically significant differences in all measured variables of static and dynamic balance; between lumbar radiculopathy (A) and control group (B). There was a significant reduction of the mean values of OASI, APSI with (p>0.0001*), T with (p=0.0001*) and MLSI with (p>0.002*) in group (B) and significant increase of the mean values of F.R.T. in group (B). While, there was a significant increase of the mean values of D.C. with (p=0.0001 *) in group (B).</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="1b7c2132d00bf2c4373f709c7ef4494b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476640,"asset_id":87198021,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476640/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198021"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198021"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198021;

The proposed electrodes have Nernstian slope values of 59.200.52±, 58.000.22± and 58.520.22± mV decade-1 for electrodes modified with 7.5, 17.5 and 7.5 mg of RN (electrode I), NaTPB (electrode II) and PTA (electrode III) ion pairing agents, respectively. It is found that the dynamic drug concentration range at 25 °C was 1.0x10-5-1.0x10-2 mole L-1 with detection limit (LOD) equal 1.0× 10-5 mol L-1 and limit of quantification (LOQ) equal 3.33×10-5 mol L-1. The response of MSPEs was pH independent in the range 2.0-6.0. The investigated electrodes have fast response time of 10, 9 and 8 s for electrodes I, II and III, respectively. These electrodes have good Nernstian response in the temperature range 10-60 °C. The slope of the straight-line obtained represented the isothermal coefficient of MSPEs which were found to be 1.594 ×10-3 , 2.151×10-3 and 2.377×10-3 V/ for electrodes I, II and III, respectively. The small values of the isothermal coefficient indicated the high thermal stability of the electrodes. The MSPEs showed a relatively long life time of 36 days. Pure, biological fluids and pharmaceutical formulation of OBCH were quantified using calibration and standard addition methods and the obtained results agreed with that of the official HPLC method. Validation parameters were optimized according to ICH recommendations.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2f857bdb5788df0f1c3af324561cda7d" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476643,"asset_id":87198019,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476643/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198019"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198019"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198019;

The oxidative damage of both liver and kidney was assessed by serum alkaline phosphatase (ALP), Gamma Glutamyl Trans-Peptidase (GGTP), Alanine and Aspartate Amino Transferase (ALT & AST) activities in addition concentrations of cholesterol, high density lipoprotein-cholesterol (HDL-c), low density lipoprotein-cholesterol (LDL-c), Triacyglycerols (TGs), urea and creatinine were analyzed. Liver lipid peroxidation (MDA), Nitric Oxide (NO), reduced glutathione (GSH) levels, and activities of both Super-Oxide Dismutase (SOD) and Glutathione Peroxidase (GSH-Px) were measured. Results: TCE administration increase serum ALP, GGTP, ALT, AST activities, cholesterol, triacylglycerols, LDL-c, urea and creatinine concentrations, besides liver MDA and NO, whereas it decreased SOD, GSH-Px activities, GSH level in liver, HDL-c in serum. Low dose of gamma rays (0.5 Gy) exposure significantly improved lipid peroxidation and oxidative injury induced by TCE. Conclusion: The study indicates that treatment with low dose of gamma rays ameliorate harmful effects induced by TCE taking in consideration the effect of gamma radiation as a stimulant of radical detoxification.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="72c1506300b1c4e2fa76703bdaf93c7b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91476696,"asset_id":87198014,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91476696/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="87198014"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87198014"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87198014;

This high level of usage requires autonomy in the system, which mainly corresponds to constraint satisfaction in the context of users' submissions. In other words, in case that the users' inputs to the robots may lead to collisions, these inputs must be altered to avoid these collisions automatically. However, these alterations must be minimal so as to preserve the users' objective in the experiment. Toward this end, the system has utilized barrier functions, which admit a minimally invasive controller-synthesis procedure. However, barrier functions are yet to be robustified with respect to unmodeled disturbances (e.g., wheel slip or packet loss) in a manner conducive to realtime synthesis. As such, this paper formulates robust barrier functions for a general class of disturbed control-affine systems that, in turn, is key for the Robotarium to operate fully autonomously (i.e., without human supervision). Experimental results showcase the effectiveness of this robust formulation in a long-term experiment in the Robotarium.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="24f40c94dfe696f0d4965799de456911" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84821903,"asset_id":77468379,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84821903/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468379"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468379"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468379;

To operate effectively under these changing conditions, algorithms developed for long-term autonomy applications require a stronger focus on robustness. Consequently, this work considers the ability to satisfy the operation-critical constraints of a disturbed system in a modular fashion, which means compatibility with different system objectives and disturbance representations. Toward this end, this paper introduces a controller-synthesis approach to constraint satisfaction for disturbed control-affine dynamical systems by utilizing Control Barrier Functions (CBFs). The aforementioned framework is constructed by modelling the disturbance as a union of convex hulls and leveraging previous work on CBFs for differential inclusions. This method of disturbance modeling grants compatibility with different disturbance-estimation methods. For example, this work demonstrates how a disturbance learned via a Gaussian process may be utilized in the proposed framework. These estimated disturbances are incorporated into the proposed controller-synthesis framework which is then tested on a fleet of robots in different scenarios.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="17a7e5c6d485332517cead20468b8a72" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84821901,"asset_id":77468378,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84821901/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468378"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468378"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468378;

However, it typically requires the exploration of a sufficiently large number of state-action pairs, some of which may be unsafe. Consequently, its application to safety-critical systems remains a challenge. Towards this end, an increasingly common approach to address safety involves the addition of a safety layer that projects the RL actions onto a safe set of actions. In turn, a challenge for such frameworks is how to effectively couple RL with the safety layer to improve the learning performance. In the context of leveraging control barrier functions for safe RL training, prior work focuses on a restricted class of barrier functions and utilizes an auxiliary neural net to account for the effects of the safety layer which inherently results in an approximation. In this paper, we frame safety as a differentiable robust-control-barrier-function layer in a model-based RL framework. As such, this approach both ensures safety ...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="bf3267cc7cbf2d1851b7363a1b0f8a5e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":84800137,"asset_id":77468375,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/84800137/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="77468375"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="77468375"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 77468375;
