Background Intravoxel incoherent motion (IVIM) can provide a unique view of tissue perfusion without the use of exogenous contrast agents. Purpose To investigate the value of IVIM in assessing grades of clear cell renal cell carcinoma (CRCC). Material and Methods A total of 107 patients with pathologically proven CRCC were included, 26 with grade I, 27 with grade II, 25 with grade III, and 29 with grade IV. These tumors were divided into low (I + II) and high grades (III + IV). Nine b values (0, 30, 50, 80, 150, 300, 500, 800, and 1500 s/mm2) were used in diffusion-weighted imaging (DWI). The tissue diffusivity (D), pseudodiffusivity (D*), and perfusion fraction (f) were calculated using bi-exponential fitting of the diffusion data. Results The D values of the four groups were 1.83 ± 0.38, 1.23 ± 0.19, 1.07 ± 0.26, and 0.37 ± 0.11 × 10–3 mm2/s ( P < 0.05). The D* values of the four groups were 0.079 ± 0.021, 0.053 ± 0.019, 0.047 ± 0.022, and 0.033 ± 0.017 ( P < 0.05). The f values of the four groups were 0.208 ± 0.09, 0.341 ± 0.12, 0.373 ± 0.15, and 0.461 ± 0.17 ( P < 0.05). Both the D and D* values correlated negatively with CRCC grading ( r = –0.677 and –0.693, P < 0.05). The f values correlated positively with CRCC grading (r = 0.699, P < 0.05). The areas of the D, D*, and f values under the ROC curves to diagnose low and high CRCC grades were 0.934, 0.837, and 0.793, respectively. The cutoff values of D, D*, and f were 1.13, 0.056, and 0.376, respectively; the diagnostic performance for low and high CRCC grading had a sensitivity of 82.0%, 80.7%, and 83.2% and a specificity of 90.8%, 86.3%, and 82.6%. Conclusion IVIM may provide information for differentiating CRCC grades.

We aimed to evaluate a newly developed peroral cholangioscopy (POCS) classification system by comparing classified lesions with histological and genetic findings. We analyzed 30 biopsied specimens from 11 patients with biliary tract cancer (BTC) who underwent POCS. An original classification of POCS findings was made based on the biliary surface’s form (F factor, 4 grades) and vessel structure (V-factor, 3 grades). Findings were then compared with those of corresponding biopsy specimens analyzed histologically and by next-generation sequencing to identify somatic mutations. In addition, the histology of postoperative surgical stumps and preoperative POCS findings were compared. Histological malignancy rate in biopsied specimens increased with increasing F- and V-factor scores (F1, 0%; F1, 25%; F3, 50%; F4, 62.5%; p = 0.0015; V1, 0%; V2, 20%; V3, 70%; p < 0.001). Furthermore, we observed a statistically significant increase of the mutant allele frequency of mutated genes with increasing F- and V-factor scores (F factor, p = 0.0050; V-factor, p < 0.001). All surgical stumps were accurately diagnosed using POCS findings. The F–V classification of POCS findings is both histologically and genetically valid and will contribute to the methods of diagnosing the superficial spread of BTC tumors.

Background: The study summarizes the findings of the 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents and compares the results with the first Chilean RC and with other countries from the Global Matrix 3.0. Methods: A Research Work Group using a standardized methodology from the Global Matrix 3.0 awarded grades for 13 PA-related indicators based on the percentage of compliance for defined benchmarks. Different public data sets, government reports, and papers informed the indicators. Results: The grades assigned were for (1) “behaviors that contribute to overall PA levels”: overall PA, D−; organized sport participation, D−; active play, INC; and active transportation, F; (2) “factors associated with cardiometabolic risk”: sedentary behavior, C−; overweight and obesity, F; fitness, D; sleep, INC; and (3) “factors that influence PA”: family and peers, F; school, D; inclusion, INC; community and built environment, B; government strategies and investments, B−. Conclusions: Chile’s grades remained low compared with the first RC. On the positive side, Chile is advancing in environmental and policy aspects. Our findings indicate that the implementation of new strategies should be developed through collaboration between different sectors to maximize effective investments for increasing PA and decreasing sedentary time among children and adolescents in Chile.

Thirty rhizosphere and non-rhizosphere soil samples from different infection grades(0, I, III, V and VII) of three typical banana plots(Jianfeng, Shiyuetian, Chongpo) infected by banana fusarium wilt (Fusarium oxysporum f. sp. cubense) in Hainan province were collected to study the microbial community functional diversity applying Biolog-ECO microplates technology. The results are as follows: (1) Overall carbon source metabolic capacities of soil microbial community weaken with increasing of infection grades of banana fusarium wilt. (2) Richness indices, Simpson indices, Shannon indices and McIntosh indices of soil microbial community gradually decreased with increasing of infection grades of banana fusarium wilt. (3) Principal component analysis show that metabolic characteristics of soil microbial community significantly change between the healthy plants and diseased plants in the same banana plot. The results would provide information for explaining the pathogenesis of banana fusarium wilt and controlling its incidence by applying microbial ecology to regulate soil environmental measures.

Background:Poland’s 2016 Report Card on Physical Activity for Children and Youth is the first assessment of child and youth physical activity (PA) in Poland using the Active Healthy Kids Global Alliance grading system. The main goal was to summarize and describe the current state of child and youth PA to increase awareness and surveillance.Methods:The systematic methodology that underpins the Active Healthy Kids Canada Report Card was adapted and applied to the Polish report card. The best available data were consolidated, reviewed by a group of experts, and used to assign the letter grades to 9 core PA indicators on a scale ranging from A (highest) to F (lowest).Results:The 9 indicators were graded as such: 1) Overall Physical Activity (D), 2) Organized Sport Participation (C), 3) Active Play (INC), 4) Active Transportation (C), 5) Sedentary Behaviors (D), 6) Family and Peers (C), 7) School (B), 8) Community and the Built Environment (C), and 9) Government Strategies and Investments (C).Conclusions:The final grades show a strong role of school in providing PA for children and youth in Poland. However, promotion of school-based sport participation appears to be insufficient by itself to sustainably promote PA in this group.

Background: Motor skill is important to young children’s overall well-being. However, there has been a paucity of work examining the demographic characteristics on young children’ motor skill. Objective: The purpose of this study was to examine the differences in motor skills across socio-economic status (SES) and grade levels in elementary school children. Method: Participants were 651 kindergarten to 2nd grade children (mean age = 6.2 ± 0.9 years; 305 girls, 346 boys) recruited from two low SES schools and another two high SES schools. Selected motor skill items were measured using the Test for Gross Motor Development-3rd Edition (TGMD-3) instrument. Data were collected once at each school during physical education class and recess period. A 4 × 3 × 2 × 2 Multivariate Analysis of Variance (MANOVA) test was employed to examine the differences among grade, SES, ethnicity, and sex on TGMD-3 scores. Results: There were significant main effects for grade (Wilks’ lambda = 0.34, F (2, 1274) = 229.6, p < 0.001) and SES (Wilks’ lambda = 0.70, F (2, 637) = 136.3, p < 0.001). Follow-up tests revealed statistically significant differences between grades on locomotor, object control and overall TGMD-3, with the 2nd graders displaying highest mean scores, followed by 1st graders and kindergarteners. Follow-up tests suggested that high SES children displaying statistically significant higher mean scores than low SES students on all motor skill variables. Conclusion: Older children demonstrated higher motor competence levels, and those with high SES displayed higher motor skill levels than lower SES children.

8029 Background: LYG is a rare angiocentric-destructive process with EBV+ B-cells and reactive T-cells. LYG is graded with grades I-II showing rare-moderate large EBV+ B-cells (usually polyclonal or oligoclonal) and grade III showing numerous large EBV+ B-cells (usually monoclonal), likely reflecting progressive transformation. Historically, steroids and/or chemotherapy have a 14 mos median survival. Methods: We are investigating Interferon-a (I-a) for grade I/II and dose-adjusted EPOCH ±Rituximab (R) for grade III LYG. Results: Characteristics of 53 pts are: male sex 68%; median age (range) 46 (17–67) and median ECOG P.S. 1 (0–3). Disease sites include lung 98%, CNS 38%, kidney 15%, skin 17%, liver 19% and nodes 4%. On study LYG grades are I-30%, II-26% and III-44%. Prior treatment was none-28%, chemotherapy± R-34%, and steroids alone-40% of pts. For grades I/II, I-a is begun at 7.5 million IUs TIW and escalated as tolerated until disease regression and continued 1 yr after CR. Of 31 patients treated with I-a, PFS is 62% at the median f/u of 5.3 yrs. Of 25 evaluable pts (3 NE; 3 TE), 60% had sustained CR for a median of 60 mos (4–175). In 9 pts who progressed on I-a, grade III was found in 5. Thus, in 20 pts with only grade I/II, 75% had sustained CR with I-a. In 11 evaluable pts with CNS disease, 81% achieved remission with I-a alone. The median time to remission is 9 mos (3–40) and median I-a dose is 20 MIU (7–40). Among 24 pts receiving DA-EPOCH±R, PFS is 40% at the median f/u of 28 mos. Of 21 evaluable pts (2 NE, 1 TE), 66% achieved CR. OS of all 53 pts is 68% at the median f/u of 4 yrs. Median EBV viral loads in 29 pts at study entry were 18 copies/10e6 genome equivalents (0–22727) (normal<200). Lymphocyte subsets in 30 pts showed a median CD4–428 (24–2322) and CD8–165 cells/mm3 (42–1316). In 12 pts in CR and with serial values, the mean CD8 cells (131 ± 44) (p2= 0.013) but not CD4 cells (65 ± 75) increased with treatment. Conclusions: High dose I-a produces sustained remissions in grade I/II LYG and is effective in CNS LYG. DA-EPOCH±R can produce durable CRs in grade III LYG. We hypothesize LYG emerges in a compromised immune milieu and undergoes progressive transformation if not effectively treated. Historical results suggest steroids may allow transformation by compromising immune function. No significant financial relationships to disclose.

Background:The first Qatar Active Healthy Kids (QAHK) Report Card was developed in 2015–2016. It is a synthesis of the available evidence on physical activity in children and youth in the state of Qatar—an assessment of the state of the nation. The report card is important for future physical activity advocacy, policy, and program development.Methods:The QAHK Report Card was inspired by the Active Healthy Kids Scotland 2013 Report Card. The methodology used in Scotland’s report card was adapted for Qatar. A Working Group identified indicators for physical activity and related health behaviors, and evaluated the available data on these indicators. The card grades were determined by the percentage of children meeting guidelines or recommendations.Results:The 2016 QAHK Report Card consisted of 9 indicators: 6 Physical Activity and Health Behaviors and Outcomes, and 3 Settings and Influences on these health behaviors and outcomes. The indicator National Policy, Strategy, and Investment was assigned the highest grade (B). Four indicators were assigned D grades: Sedentary Behavior, Dietary Habits, Organized Sports Participation, and Family and Peer Influence. Physical Activity and Obesity were both graded F. Two indicators could not be graded due to insufficient data and/or absence of a recommendation: Active and Outdoor Play, and Community and School Influence.Conclusions:The QAHK Report Card identified weaknesses and gaps in the evidence on physical activity and health in children and youth in Qatar. The quality of evidence was poor for some indicators, with some data collection methods of limited validity and reliability, or only available for a limited age range, so the grades are best estimates of the current situation in Qatar. Future surveys and research using objective physical activity measures will support the development of a second QAHK Report Card by 2018.

Abstract Fludarabine (FLU) is a chemotherapeutic and immunosuppressive agent used in reduced intensity conditioning (RIC) regimens prior to hematopoietic stem cell transplantation. High exposure to F-ara-A, the active metabolite of FLU, has been associated with more treatment related mortality (TRM). No standard dosing models allow estimation of exposure and individualized dosing. We developed a population pharmacokinetic model for adults that estimates F-ara-A clearance (Cl) from which area under the curve (AUC0-∞) is calculated.(Clin Pharmacol Ther, Vol95, S87, March 2014) We retrospectively tested the performance of the model by associating individual predicted AUC 0-∞to clinical outcomes. TV F-ara-A CL (L/hr) = (7.04 + 3.9 * (CrCl/85) * (70/IBW)) * (IBW/70)0.75 AUC 0-∞ (μg-hr/ml) = Administered dose in F-ara-A equivalents (mg)/Estimated TV F-ara-A Cl (L/hr) Adult HCT patients (n=301, 2008 to 2014) who received IV FLU in their conditioning regimen were included. FLU doses, actual body weight, height, serum creatinine, along with TRM, engraftment and acute GVHD were reviewed. TRM was defined as death without relapse or disease progression. GVHD was staged and graded according to the standard GVHD criteria. The median age (range) was 58 yrs. (18-75). 131(43.5%) received PBSCT, 31(10.3%) bone marrow and cord blood in 139(46.2%). FLU doses were 25-40 mg/m2/day; nearly all x 5 days. The median (range) daily dose was 67 mg (38 mg-100 mg). The pharmacokinetic model was used to estimate the F-ara-A Cl and then predict their AUC0-∞ from the first dose and the total cumulative AUC0-∞. Recursive partitioning regression analysis was used to determine the optimal cut points for the first dose AUC0-∞ and cumulative AUC0-∞towards clinical outcomes. The cumulative incidence of engraftment, TRM and acute GVHD (grades II-IV and III-IV) was calculated using death prior to event as a competing risk. The proportional hazards model of Fine and Gray was used to assess the association of F-ara-A exposures towards TRM, acute GVHD and engraftment. The median (range) F-ara-A Cl, AUC0-∞ and cumulative AUC0-∞ predicted from the model were 10.92 L/hr (7.51-15.37), 4.79 μg-hr/ml (2.40 -7.52) and 23.93 μg-hr/ml (11.20-37.62), respectively. Patients with a higher first dose AUC0-∞ ≥6 μg-hr/ml had a higher incidence [95%CI] of day 100 TRM (20% [7-33%] vs 6% [4-9%], p<0.01) compared to those with <6 μg-hr/ml. Similarly, higher cumulative AUC0-∞ ≥30 μg-hr/ml was also associated with higher risk of day 100 TRM (21% [7-34%] vs 6% [3-9%], p<0.01) compared to those <30 μg-hr/ml. Both PK measures [first dose AUC0-∞ ≥6 μg-hr/ml and cumulative AUC0-∞≥30 μg-hr/ml] had higher risks of 12 month TRM (32% [16-48%] vs 15% [11-20%], p=0.02) and (34% [17-51%] vs 15% [11-20%], p=0.02), respectively. An AUC0-∞ ≥4 μg-hr/mL led only to a marginally higher risk of 6 month GVHD grades II-IV and III-IV (42% [35-48%] vs 28% [14-41%] p=0.07 and 43% [37-50] vs. 30%[16-44%], p=0.06, respectively) compared to <4 μg-hr/ml. However a cumulative AUC0-∞≥20 μg-hr/ml was associated with a significantly greater risk of acute GVHD grades II-IV (43% [36-49%] vs. 26% [14-38%], p= 0.02) and grades III-IV (44%, [38-51%] vs, 28% [15-41%], p=0.03). Lower F-ara-A clearance and higher AUC 0-∞ were associated with greater risks of TRM and acute GVHD. These data support personalizing FLU dose rather than using empirical body surface area based dosing. Targeting FLU therapy may improve outcomes after HCT.

Syftet med studien är att undersöka hur lärare använder sig av högläsning i undervisning för att främja elevernas läsförmåga och hur detta syns i elevernas aktiviteter. Teorin som studien bygger på är det sociokulturella perspektivet med ursprung i Lev Vygotskijs teorier om lärande, utveckling och språk. I studien har fem lärare som arbetar i årskurserna F–3 blivit intervjuade med en semistrukturerad intervju. Lärarna har även blivit observerade under en av sina högläsningslektioner för att se hur de använder sig av högläsning för att utveckla elevernas läsförmåga. Resultatet visar att lärarna försöker använda sig av högläsning dagligen i sin undervisning då de anser att den ger väldigt mycket. Lärarna anser att högläsningen utvecklar elevernas ordförråd, läsförståelse, läslust och koncentrationsförmåga. Utifrån observationerna, tidigare forskning och lärarnas intervjuer visar resultatet även att lärarna använder sig av olika arbetssätt och metoder för att eleverna ska få möjlighet att utveckla sin läsförmåga.The purpose of this study is to examine some teachers' view of the effect of read-alouds on the development of pupils' reading skills, as well as the opportunities the pupils get to develop their reading skills in teacher practices of reading aloud. The study is based on the sociocultural perspective originating in Lev Vygotsky theories on learning, development and language. In this study, five teachers working in preschool and grades 1–3 have been interviewed using qualitative interviews. Teachers have also been observed during one of their read-aloud lessons in order to see how they use reading aloud to develop pupils' reading skills. The results show that the teachers try to read aloud daily in their teaching because they find it has great advantages. The teachers believe that reading aloud develops pupils' vocabulary, reading comprehension, love of reading and concentration. Based on previous research, observation and teacher interviews, the results also show that teachers use approaches to and methods for giving their pupils opportunity to develop their reading skills.

Syftet med studien är att undersöka om det finns lämpliga stödåtgärder att införa i svenskundervisningen för elever med läs- och skrivsvårigheter/dyslexi i årskurs F-3. Vi vill få en fördjupad kunskap om vilka sorts tidiga tecken det finns på att en elev har läs- och skrivsvårigheter/dyslexi samt vilka svårigheter som är förknippade med funktionsnedsättningen. För att uppnå ett resultat valdes en kvalitativ forskningsmetod i form av personliga intervjuer med lärare, specialpedagoger samt individer med dyslexi. Den teori som ligger till grund för studien utgår ifrån ett språk- och kunskapsutvecklande synsätt. Teorin har rötter i uppbyggnaden av språksystemet. I resultatet framkom det att lärarna saknar kunskap om vad läs- och skrivsvårigheter/dyslexi innebär. Detta skapar en problematik eftersom de direkt behöver lämna över arbetet till en specialpedagog. Resultatet pekar också på att strukturen i undervisningen, kompensatoriska hjälpmedel och intensivläsning är lämpliga och förebyggande stödåtgärder för elever med läs- och skrivsvårigheter/dyslexi. Den slutsats vi drar är att det saknas övergripande och fördjupad kunskap om vilka svårigheter läs- och skrivsvårigheter/dyslexi medför och hur pedagogerna ska hantera detta i undervisningen. Utifrån de fyra intervjupersonerna framkom det liknande förslag på stödåtgärder. Intensivläsningen var den stödåtgärd som var mest påtalad bland intervjupersonerna. Med hjälp av teorin kunde vi dra slutsatsen att intensivläsning kan utvecklas och varieras med hjälp av genrepedagogiken.

Det sägs att barn har lätt att lära språk då de tycks uppskatta att lära sig nya ord och är nyfikna på språk. Jämfört med många andra länder påbörjas språkinlärningen i Sverige relativt sent. I den här litteraturstudien undersöks viktiga förutsättningar för inlärning vid en tidig språkstart samt hur elever i årskurserna F-3 lär sig uttal i engelska som andraspråk. Som grund för analysen av studiernas resultat används Critical Period Hypothesis (CPH), Krashens teorier om andraspråksinlärning samt Piagets teorier om barns utveckling. Fem studier har analyserats. Resultatet av litteraturstudien påvisar nyttan av tidig språk- och uttalsinlärning men att det är i hög grad beroende av lärarnas kompetens. Vidare visar resultatet att uttalsinlärning gynnas mest av metoder som innehåller direkt respons på elevernas uttal men även att passiva inlärningsmetoder (t.ex. lyssna på sång) gynnar inlärning av uttal som ligger nära modersmålet. När det gäller barns språk- och uttalsinlärning är det viktigt att ha rätt kompetensen hos lärarna och att flera metoder (direkt och indirekta) kan gynna inlärningen.

Sammanfattning Tidigare forskning visar att elever i de yngre åren i huvudsak möter skönlitterära texter och att detta kan innebära svårigheter för dem i klass 4 då de förväntas förstå olika texttyper. Denna studie undersöker vilka texttyper elever i förskoleklass till årskurs 3 får möta på två olika skolor i två skilda kommuner och om lärarna anser att det kan påverka elevers läsförståelse och läsintresse. Undersökningen gjordes genom kvalitativa intervjuer med verksamma lärare och baseras på en lärandesyn utifrån ett sociokulturellt perspektiv och begreppet literacy. Resultatet visar att de yngre barnen på de två deltagande skolorna till stor del får möta olika texttyper och att lärarna anser att det främjar både läsförståelse och läsintresse.Abstract Previous research show that students in the younger years mainly meets fictional text types and that this may cause difficulties for them in 4th-grade when they are expected to understand different kinds of text. This study examines which types of text students in preschool to grade three meet at two different schools in two separate municipalities, and if teachers believe that it can affect students reading comprehension and interest in reading. The survey was conducted through qualitative interviews with practicing teachers and is based on a learning approach from a sociocultural perspective and the literacy concept. The result show that the younger children at the two participating schools for the most part get to meet different types of texts and that the teachers considers it promotes both reading comprehension and interest in reading.

The aim of this study was to examine how a group of teachers in the same primary school work with fiction read-alouds in the Swedish teaching. The collected material was analysed by using Langer’s (2005) theory about imagination worlds. Two questions were then formulated to answer the purpose of the study: How do the teachers plan their fiction read-alouds in Swedish teaching? and How do the teachers describe the implementation of their read-alouds? The result shows that all of the teachers plan their fiction read-alouds with different types of preparation. This preparation includes: choosing the right book, which the teachers claim is dependent on several factors such as the students’ knowledge level or interests; reading the book before the read-aloud; and introducing the book in an interesting way during the read-aloud, which creates a pre-understanding of the content. Lastly, the teachers revealed that a large part of their planning work consists of creating post-reading tasks which are primarily aimed at developing students’ writing. The result also shows that the teachers have distinct rules for the implementation of their read-alouds. These rules help the teachers create favourable conditions for engaging students in the world of fiction. During read-alouds, the teachers embody the text through the use of their voices and body language. The importance of conversation during the read-aloud, with the primary purpose of helping students understand the content of the story, was also emphasized. The teachers also claim that conversation also gives their students a chance to think out loud and to reflect on the reading, thus gaining the opportunity to share each other’s thoughts.

Att besitta en god läsförståelse är viktigt för att kunna fungera i samhället men också lyckas i skolan. Läsförståelse är en komplex process vilken innefattar många olika delar. För att eleverna ska utveckla sin läsförståelse är lärarens val i undervisningen avgörande. I forskning framkommer mycket information om hur läraren kan arbeta för att utveckla läsförståelse. Forskning är dock bristfällig rörande hur lärare beskriver att de arbetar i praktiken med läsförståelse och vad de uppfattar som gynnsamt för att alla elever ska utveckla läsförståelse. Särskilt lite forskning finns gällande elever i läsförståelsesvårigheter. Syftet med denna studie är därför att öka kunskapen om hur lärare i F-3 beskriver att de arbetar för att utveckla läsförståelse. Särskilt fokus läggs på elever i läsförståelsesvårigheter. Syftet avses att uppfyllas med hjälp av följande frågeställningar: · Hur förklarar och motiverar lärare i årskurs F-3 sitt arbete med att utveckla elevers läsförståelse? · Hur förklarar och motiverar lärare i årskurs F-3 sitt arbete med att utveckla läsförståelse för elever i läsförståelsesvårigheter? I studien användes en kvalitativ semistrukturerad fokusintervju för att samla in materialet. Det var sex lärare från tre skolor som deltog. Resultatet analyserades sedan med utgångspunkt i ett sociokulturellt perspektiv. Resultatet i studien visar att lärarna anser det är viktigt att arbeta med utveckling av förmågorna avkodning, ord- och begreppsförståelse samt förmågan att använda läsförståelsestrategier genom varierade arbetssätt. För de elever i läsförståelsesvårigheter är den komponent som eleven brister i gällande ovanstående det som hen behöver arbeta med både genom intensivträning och genom anpassade arbetsformer tillsammans i klassen, där arbete med bildstöd och förförståelse kan fungera som stödjande verktyg för eleven. Sammanfattningsvis är det svårt att beskriva exakt hur lärare arbetar för att bana väg för alla elevernas läsförståelseutveckling. Alla elever är olika och läraren behöver anpassa sin undervisning efter elevgruppen.Developing reading comprehension is an important competence for being able to function in society but also to succeed in school. Reading comprehension is a complex process which involves many different parts. For students to develop their reading comprehension, the teacher's choice in teaching is crucial. Research reveals a lot of information about how the teacher can work to develop reading comprehension. However, there is a lack in research regarding how teachers describe that they work in practice with reading comprehension and what they perceive as favorable for all students to develop reading comprehension. There is very little research regarding students with reading comprehension difficulties. The aim of this study is therefore to increase the knowledge of how teachers in grades F-3 describe that they work to develop reading comprehension. A special focus is placed on students with reading comprehension difficulties. The aim will be fulfilled with the help of the following questions: • How do teachers in grades F-3 explain and motivate their work to develop students' reading comprehension?• How do teachers in grades F-3 explain and motivate their work to develop reading comprehension for students with reading comprehension difficulties? In the study, qualitative semi-structured focus interviews are used to collect data. Six teachers from three schools participated. The results were then analyzed based on a socio-cultural perspective. The results of the study show that the teachers consider it important to work with the development of the abilities decoding, word and concept comprehension as well as the ability to use reading comprehension strategies through varied working methods. For students with reading comprehension difficulties, the component that the student lacks in the above is what he or she needs to work with both through intensive training and through adapted working methods together in class, where work with pictures and pre-understanding can serve as supportive tools for the student. In summary, it is difficult to describe exactly how teachers work to pave the way for all students' reading comprehension development. All students are different, and the teacher needs to adapt his or her teaching to the student group.

Uma rotulação L(3,2,1) de um grafo G é uma função f de V(G) em S = {0,1,...,k} tal que |f(u)-f(v)| >= 4 - d(u,v) para quaisquer dois vértices u, v em V(G), em que d(u,v) é a distância entre u e v em G. O span de uma rotulação L(3,2,1) f é o maior rótulo k em S. O menor span que uma rotulação L(3,2,1) pode atribuir a um grafo G é denotado por lambda_{3,2,1}(G). Neste trabalho, provamos que lambda_{3,2,1}(G) = 25 para todo grafo subcúbico G sem vértices adjacentes de grau máximo. Além disso, provamos que lambda_{3,2,1}(G) <= 16 para grafos subcúbicos G com vértices de grau 3 à distância pelo menos 4.

Given a graph G and a proper k-coloring f of G, a b-vertex in f is a vertex that is adjacent to every color class but its own. If every vertex is a b-vertex, then f is a fall k-coloring; and G has a subfall k-coloring if there is an induced H $\subseteq$ G such that H has a fall k-coloring. The subfall chromatic number of G is the largest positive integer $\psi_{fs}(G)$ such that G has a subfall $\psi_{fs}(G)$-coloring. We prove that deciding if a graph G has a subfall k-coloring is NP-complete for k $\geq$ 4, and characterize graphs having a subfall 3-coloring. This answers a question posed by Dunbar et al. (2000) in their seminal paper. We also prove polinomiality for chordal graphs and cographs, and present a comparison with other known coloring metrics based on heuristics.

In many LNG receiving terminals worldwide, the cryogenic heat of imported LNG which was liquefied by using 10% energy of natural gas supply1), 2), has been wasted into the sea water mainly through heat exchangers like ORVs (Open Rack Vaporizer)3). This cryogenic heat of 110 K (-256 F) class is considered, however, as an excellent energy source to apply thermodynamic cycles. Several literature, accordingly, are found to improve such high-grade energy potential of LNG regasification process as a low temperature sink, combining with fired heater at 1,100 K (1520 F) class or GT main exhaust gas at 700 K (800 F) class as a high temperature source, through Brayton and Rankine cycles5),6),7),8),9). This paper presents a typical example of closed “Ericsson” cycle which has the minimum cycle temperature of 157 K (-176 F) from LNG cryogenic heat and the maximum of 550 K (531 F) from the partial HRSG exit heat mixed with the partial GT exit gas. This closed gas turbine, from viewpoints of minor modification to existing power plants and no energy impacts for high temperature source, which would be better than the above-described idea, is able to offer 35% thermal efficiency. And it is recognized that this system would be superior to existing cryogenic generation systems of 20% class operated by Rankine Cycle.

It has become apparent with the development of creep strength enhanced ferritic steels, the mandatory ASME B31.1 Chapter VII and the non-mandatory ASME B31.1 Appendix V guidelines require a more rigorous method to manage the Grade 91 piping integrity at Genesee Unit 3. Given the relatively young age of Genesee Unit 3, three questions have been asked: 1) when do the examinations start, 2) what locations should be examined first, and 3) how often should the same location be reexamined? To ensure that the best value is obtained from the reexamination budget, a five-step process can be effectively used to define and categorize the scope of each set of reexaminations in the girth weld integrity management program. The five processes are performing the following analyses: 1) an evaluation of the historical information, 2) piping system hot and cold walkdowns, 3) as-designed and as-found piping stress analyses, 4) creep life consumption evaluations, including elastic and inelastic axial and radial stress redistributions, and 5) creep crack growth curve analyses. Reexaminations of the few critical lead-the-fleet weldments are performed with lower examination costs and higher confidence. Evaluations of the Genesee Unit 3 main steam (MS) piping system revealed that the applicable weldment stress is probably the most significant parameter in determining the Grade 91 girth weld critical reexamination locations and intervals. ASME B31.1 piping stress analyses of the MS piping system have sustained load stress variations of more than 100% among the girth welds. The lower bound American Petroleum Institute (API) 579 creep rupture equation for Grade 91 operating at 1,060°F (571°C) indicates that the creep life is a function of stress to the power of 8.9; consequently, a 15% stress increase results in about 2/3 reduction of creep rupture life. Creep crack growth analyses of several of the MS piping system weldments revealed that the creep crack growth time to grow from 1/8 inch to through-wall is a function of stress to the power of 8.8; consequently, a 15% stress increase results in about 2/3 reduction of time for a 1/8-inch crack to grow through-wall. This evaluation reveals that a few critical lead-the-fleet locations should be reexamined most frequently and justification can be provided for much longer reexamination intervals of the remaining girth welds with much lower applied stresses.

Abstract Introduction Cancer is the leading cause of death worldwide with elderly patients being predominantly affected. There seems to be a bias against administering chemotherapy to elderly patients with fewer elderly patients receiving chemotherapy as compared with their stagematched younger patients because of concerns about their capacity to endure treatment. To make personalized treatment decisions and to anticipate serious adverse effects, a toxicity prediction tool that can be computed at the bedside is the need of the hour. This well-validated score has not been tested in the Indian population. So, we decided to test the same score in our patients and try to correlate the score with the observed toxicity. Objectives This study was aimed to determine geriatric functional status by means of a standardized geriatric score and to correlate geriatric score with observed chemo toxicity. Materials and Methods Fifty consecutive elderly patients (age > 60 years) with a diagnosis of cancer and scheduled for chemotherapy were recruited. These patients were evaluated using the geriatric assessment tool which is based on functional, nutritional, and psychological status. After that patient’s pretherapy, chemo toxicity score or geriatric score was calculated using a published well-validated tool that consisted of 11 prechemotherapy variables as follows:a) Age of patient,b) Cancer typec) Planned chemotherapy dose,d) Planned number of chemotherapy drugse) Hemoglobin,f) Creatinine clearanceg) Geriatric questions like -i. How is your hearing?ii. Number of falls in past 6 months?iii. Can take your own medicines?iv. Does your health limit you in walking one block ? during past 4 weeksv. How much of time has your physical health or emotional problems interfered with your social activities (like visiting with friends, relatives etc.)The patients were then followed from the beginning to the end of six cycles of their chemotherapy regimen. Toxicities were noted after each clinical encounter by using the NCI-CTCAE, version 3.0.25. Results General characteristics: the mean age of participants was 66 years (standard deviation [SD] = 4.6 and range: 60–85 years). Of them, 60% received polychemotherapy and 82% received standard doses of chemotherapy. The mean score on activities of daily living was 66.7, comorbidity score was 2.7, the psychological scale was 63.8, the social-activity scale was 54.3, and social-support scale was 64.1. The mean pretherapy toxicity score is 7.24 according to the toxicity calculator. At least one grade 3 to 5 toxicity occurred in 30% of the patients (66% of grade 3, 20% of grade 4, and 13.3% of grade 5). The correlation between the predicted score and observed graded toxicity score by Pearson’s scale (α = 0.05) was 0.63. Conclusion The prediction model is easy to use, thus increasing the feasibility of incorporation in daily practice is important. It may enable oncologists to better assess the risk/benefit ratio and to adjust the treatment accordingly.

Introdução: O cenário brasileiro se destaca pela liderança no setor do agronegócio, o qual vem impactando na crescente utilização de insumos importados, como agroquímicos sintéticos. Visto que, o fungo Fusarium solani é capaz de infectar diversas culturas de grande interesse econômico como por exemplo: soja, milho, feijão e trigo, em diferentes estágios de desenvolvimento, sendo que a complexidade do solo e a variabilidade genética existentes no F. solani tornam as doenças causadas por ele de difícil controle, surgiu-se a necessidade de cultivos de maior qualidade e baixa nocividade, tanto a saúde humana, como ao meio ambiente, gerando assim uma procura por novos agentes de controle biológico, como fungos do gênero Trichoderma, que veio a contribuir diretamente na construção desse cenário mais sustentável e produtivo. Objetivos: Avaliar a eficiência de isolados do gênero Trichoderma, contra o fitopatógeno F. solani, utilizando-se do teste de avaliação de efeito dos metabólitos voláteis. Material e Métodos: Foi realizado o teste de avaliação de efeito de metabólitos voláteis, que consistiu em posicionar fundos de placas de petri umas sobre as outras, após ter vertido em cada uma delas, em meio de cultura Batata Dextrose Ágar (BDA). Foram posicionados os discos de 3 mm dos isolados de Trichoderma, na parte inferior das placas e na parte superior discos de 3 mm do patógeno F. solani, mantidos a 25ºC, por 7 dias, utilizando-se do controle como referência para o crescimento. O teste foi submetido à análise de variância e de médias, comparadas pelo teste de Scott-Knott, a 5% de probabilidade, empregando-se ao software estatístico Sisvar®. Resultados: Após o período de 7 dias do início do teste, foi possível notar que os isolados de Trichoderma, foram capazes de produzir metabólitos voláteis suficientes, inibindo assim o crescimento do fitopatógeno. Conclusão: Com base nos resultados obtidos, foi possível concluir que, os isolados do fungo Trichoderma, possuem potencial para atuar na inibição do crescimento do fitopatógeno F. solani, visto que, além de ser sustentável e de grande interesse ao mercado de biocontrole, contribui também com o crescimento e maior produtividade no cultivo ao qual foi aplicado.

The objective of this study was to explore an approach for measuring fatigue crack growth rates (da/dN) for Cr-Mo pressure vessel steels in high-pressure hydrogen gas over a broad cyclic stress intensity factor (ΔK) range while limiting test duration, which could serve as an alternative to the method prescribed in ASME BPVC VIII-3, Article KD-10. Fatigue crack growth rates were measured for SA-372 Grade J and 34CrMo4 steels in hydrogen gas as a function of ΔK, load-cycle frequency (f), and gas pressure. The da/dN vs. ΔK relationships measured for the Cr-Mo steels in hydrogen gas at 10 Hz indicate that capturing data at lower ΔK is valuable when these relationships serve as inputs into design-life analyses of hydrogen pressure vessels, since in this ΔK range crack growth rates in hydrogen gas approach rates in air. The da/dN vs. f data measured for the Cr-Mo steels in hydrogen gas at selected constant-ΔK levels demonstrate that crack growth rates at 10 Hz do not represent upper-bound behavior, since da/dN generally increases as f decreases. Consequently, although fatigue crack growth testing at 10 Hz can efficiently measure da/dN over a wide ΔK range, these da/dN vs. ΔK relationships at 10 Hz cannot be considered reliable inputs into design-life analyses. A possible hybrid approach to efficiently establishing the fatigue crack growth rate relationship in hydrogen gas without compromising data quality is to measure the da/dN vs. ΔK relationship at 10 Hz and then apply a correction based on the da/dN vs. f data. The reliability of such a hybrid approach depends on adequacy of the da/dN vs. f data, i.e., the data are measured at appropriate constant-ΔK levels and the data include upper-bound crack growth rates.

Low rank or grade coals (LGC) are widely distributed over the world. Coal plays a vital role in the global energy demand especially through power generation and it mitigates the energy poverty. The major challenges by the utility of coal as regarding to energy security, a risk of climate change, and increasing of the energy demands are the main portfolio to develop the advanced technology for coal beneficiation. The gradual depletion of high quality coal and cost effective which become a significant issue for power generation while the low grade coals were served as low cost fuel and as an alternative energy security issue. In current research the low grade coal (>35% ash) has been upgraded to higher grade (<10%) by chemical cleaning method. The low grade coal was selected from Mahanadi Coalfields Limited, Odisha, India. Each test was conducted of 50 g coal (250 μm particle size) with 40% NaOH at 100 °C for 3 h and followed with 20% of H2O2, H2SO4, HCl, and HF acids at similar conditions. The research study revealed that ash content (mineral matter) of coal is reduced to >70% by NaOH followed HF treatment as compared to other solvents. The greater liberation of mineral results increases the ash reduction from low grade coal because mineral associated in the coal matrix may formed elution by the leaching effect. The greater extent of demineralization was caused due to the high affinity of OH− and F− with minerals in the coal matrix. The characterization of pre and post treatment coal and coal ash was investigated by the FESEM, XRF and XRD analysis. Overall the current research study challenges the chemical cleaning of low grade coal has been efficient techniques for reducing the minerals to a certain limit.

Sawmills in the Canadian province of British Columbia (BC) will soon be confronted with a collective wood waste disposal problem (bark, sawdust and shavings) of about 3 Million bone dry tonne/y at an average wet basis moisture content of about 45%. About 40 existing sawmill beehive burners presently incinerate this waste. Emissions from these beehive burners exceed current provincial particulate limits. Markets for the waste — board plants, sawdust digesters, charcoal plants, etc. — are limited. The economics of 25 to 50 MW wood-fired, steam power plants is poor. 6¢/kW.h is needed to finance a plant; the major utility offers 2¢/kW.h. This paper describes a 3 MW to 5 MW, Nuovo Pignone PGT-5 co-generation plant fuelled by the 2000°F (1093°C) exhaust from a Heuristic EnvirOcycler, a two-stage, wood waste incinerator. The exhaust meets BC’s particulate limit of 0.052 grains/dscf (120 mg/Nm3). 37 to 65 Million Btu/h (39 to 68 GJ/h) of waste heat can be recovered from the system exhausts. In this application the PGT-5’s external combustion chamber is replaced by a “recuperator”, i.e., a high temperature, gas-to-air, heat exchanger. Two variations of the basic system are examined. One features a larger than necessary EnvirOcycler to generate additional steam in the waste heat boiler. The other variation discusses heating 1,550°F (843°C) air from the recuperator up to 1,796°F (980°C) with natural gas. The extra power generated can cost as little as 1.9¢/kW.h.
