Гастроинтестиналне нематоде представљају веома значајне паразите домаћих животиња, нарочито код малих преживара. Код оваца обољења најчешће имају субклиничан ток са смањењем телесне масе и производње, а понекад може доћи и до видљивих клиничких симптома попут анорексије, анемије, јаке дијареје и губитка протеина што све заједно може довести и до угинућа. Комерцијални лекови попут бензимидазола и макроцикличних лактона су се деценијама са успехом користили за контролу ових паразита. Међутим, нерационална примена ових лекова је довела до развоја антихелминтичке резистенције, опадања њихове ефикасности и последичних економских губитака који угрожавају одрживост гајења оваца. Поред тога, примена комерцијалних препарата је повезана и са резидуама које остављају у животињским производима и животној средини, а присутан је и раст цене ових препарата. Због тога се активно трага за новијим стратегијама за контролу ових паразита, а у циљу успостављања интегрисаног приступа који подразумева примену више различитих стратегија. Са једне стране, ту спадају стратегије рационалне примене комерцијалних препарата заснованих на рефугији (циљани третмани, циљани селективни третмани), као и комбинација и ротација антихелминтика из различитих хемијских група. Са друге стране, интегрисан приступ подразумева и употребу различитих алтернативних стратегија попут генетске селекције животиња природно отпорних на нематоде, рационалног управљања пашњацима, избалансиране исхране уз допунска хранива, биолошке контроле (употреба гљива, бактерија и слично), развоја вакцина као и употребе ботаничких препарата (биљака и њихових производа попут екстракта и етарских уља). Различита истраживања су доказала ефикасност наведених стратегија у контроли гастроинтестиналних нематода оваца, при чему се најбољи резултати постижу њиховом комбинованом применом. На овај начин је могуће успорити развој и ширење антихелминтичке резистенције, као и постићи одрживу контрола ових паразита и смањење економских губитака.

Месо је нутритивно вредна намирница, због чега је склона микробиолошкој контаминацији и квару. Главне, храном преносиве патогене бактерије, као што су Salmonella spp., Listeria monocytogenes и Yersinia enterocolitica, често се повезују са месом. Ови узрочници се налазе на врху листе пријављених зооноза код људи. Како би се повећао микробиолошки квалитет меса, последњих деценија су у употреби алтернативне супстанце, између осталог и етарска уља, једињења добијена екстракцијом из биљака, које чине “безбедну” алтернативу хемијским и синтетским адитивима, у циљу постизања антимикробних и антиоксидативних ефеката. Многа истраживања приказују антибактеријско дејство етарских уља. Ефекат деловања етарских уља на бактерије огледа се у инхибицији њиховог раста (бактериостатски ефекат) или њиховој деструкцији (бактерицидни ефекат). У овом раду приказана су комерцијално доступна етарска уља препозната као безбедна за прехрамбену употребу, њихова антибактеријска дејства против храном преносивих бактерија у in vitro условима, механизми деловања ових етарских уља на Грам позитивне и Грам негативне бактерије, као и њихова примена на моделу меса.
ФОСФАТИ И НИТРИТИ – НАЈЧЕШЋЕ КОРИШЋЕНИ АДИТИВИ У ИНДУСТРИЈИ МЕСА

Published: March 2024

Прехрамбени адитив је свака супстанца која се, без обзира на њену храњиву вриједност, не користи као храна, нити представља карактеристичан састојак хране, али се из технолошких разлога додаје храни у току производње, прераде, припреме, обраде, паковања, транспорта или чувања, тако да директно или индиректно преко својих међупроизвода постаје или може да постане састојак хране. Захваљујући вишеструкој улози у индустрији меса, најчешће коришћени адитиви су нитрити и фосфати. Према Правилнику о адитивима у храни (Службени гласник Републике Српске, 96/20), максимално дозвољена количина фосфорне киселине и фосфата (Е 338 - Е 452), која се може додати производима од меса појединачно или у комбинацији (изражена као Р2О5), износи 5 g/kg. У многим студијама спомиње се повезаност између високог уноса фосфатних адитива и разних обољења код човјека. Нитрити су конзерванси који се додају производима од меса ради побољшања квалитета, трајности и безбједности производа и у највећем броју производа од меса не смију се додати у количини већој од 150 mg/kg. Због могућности настајања канцерогених нитрозамина под одређеним условима у производима од меса, постоји потенцијална опасност по здравље људи. Циљ истраживања био је да се одреди садржај резидуалног нитрита и додатих фосфата (изражени као фосфор пентоксид Р2О5) у производима од меса који потичу са тржишта Републике Српске (Босне и Херцеговине) и усаглашености са захјевима регулативе. Резултати истраживања су показали да су утврђене количине резидуалног нитрита и додатих фосфата биле у оквиру дозвољених граница за додавање у различите категорије и врсте производа од меса према важећој регулативи. То потврђује адекватну примјену нитрита и фосфата и здравствену исправност производа. У циљу заштите здравља потрошача важно је континуирано праћење употребе фосфата и нитрита у индустрији меса.

Transport i utovar u prevozno sredstvo je potencijalni izvor stresa za konje, što posljedično može dovesti do narušavanja koncepta dobrobiti životinja. Cilj istraživanja bio je da se ispita prisustvo stresne reakcije konja tokom utovara u prevozno sredstvo, iskazane kroz promjenu frekvence pulsa, kao indikator stresne reakcije. Istraživanjem je obuhvaćeno 25 konja, starih između 4 i 20 godina. Verifikacija frekvence rada srca sprovedena je uz upotrebu veterinarskog stetoskopa sa dvostranom membranom i kontrolisana uz pomoć mjerača rada srca. Tokom mirovanja u štali (prvo mjerenje) ustanovljena je frekvenca pulsa između 29 i 40 otkucaja u minuti. Drugo mjerenje izvršeno je u momentu utovara, kada su konji zakoračili na utovarnu rampu prevoznog sredstva, te je ustanovljena frekvenca pulsa između 42 i 72 otkucaja u minuti. Rezultati t-testa ukazuju na postojanje statistički značajne razlike u frekvenci pulsa između prvog i drugog mjerenja. Rezultati ovog istraživanja ukazuju da utovar konja u prevozno sredstvo može uzrokovati stres, koji se manifestuje povećanjem frekvence pulsa. Sklonost konja da lako stvaraju navike omogućava njihov trening s ciljem smanjenja nivoa stresa prilikom utovara u prevozno sredstvo, što može doprinijeti poboljšanju dobrobiti konja, a u isto vrijeme smanjiti nivo stresa i rizik od povreda konja i osoblja.

Authors: Shilova Natalia Petrovna
Published: March 2024

The article presents the results of a study on the role of the level of education received in shaping the time perspective of the future in adolescence. The object of the study is boys and girls from 15 to 23 years old. The subject of the study is the peculiarities of the time perspective in youth, related to the level of education received. The purpose of this research is to study the differences in the characteristics of the time perspective in adolescence, depending on the level of education received. And the hypothesis was the assumption that there are differences in the characteristics of the time perspective of boys and girls related to the level of education received. The author examines in detail the aspect of the topic related to the differences in the time perspective of boys and girls depending on the level of education received. The study was conducted using the method of unfinished sentences of J.Nyutten. The main conclusions of the study were the following statements: - the future of teenagers, boys and girls studying at school is focused on the time period "schooling", and for boys and girls studying at colleges this is the time of "vocational education after school"; - the future of university students is focused on the time period "professional autonomy, work", but this is not relevant for college students. The author's scientific contribution to the study of the topic was to clarify the available data on the formation of a time perspective in youth. The novelty of the study lies in the fact that for the first time the features of the time perspective in youth associated with studying in educational institutions such as schools, institutions of secondary special education or universities have been identified.

Inhomogeneous magnetic field is introduced into pulsed laser deposition process, in order to find new properties of diamond-like carbon film grown under magnetic field, thereby offering the theoretical and experimental basis for further enhancing sp3-bond content in this film. Distribution of the magnetic strength and flux lines induced by a rectangular permanent magnet is calculated. And then, flying trace of the carbon ions in the magnetic field is also simulated by the iterative method, which indicates that the carbon ions cannot expand freely and they are confined and accumulate around the center region of the magnet source. Beside the surface interference, the measurement and the fitted results of ellipsometry parameters show that magnetic field exerts an important influence on layer-thickness distribution and optical constant of the pulsed laser deposition-grown diamond-like carbon film. Meanwhile, it is indicated that the inhomogeneity of the layer-thickness distribution and optical constant increase when the magnetic strength is higher. Micro-structure of diamond-like carbon film is affected seriously by magnetic field, which is indicated by Raman spectra. Magnetic field can enhance the local stress in the carbon matrix net, increasing the sp3-bond content. Theoretical research and experimental research both show that a suitable magnetic strength can excite micro-structure of diamond-like carbon film significantly, and the high-quality diamond-like carbon coating with practical application value will be obtained by technological adjustment.

Published: March 2024

Endometrial decidualization, a prerequisite for successful pregnancies, relies on transcriptional reprogramming driven by progesterone receptor (PR) and bone morphogenetic protein (BMP)-SMAD1/SMAD5 signaling pathways. Despite their critical roles in early pregnancy, how these pathways intersect in reprogramming the endometrium into a receptive state remains unclear. To define how SMAD1 and/or SMAD5 integrate BMP signaling in the uterus during early pregnancy, we generated two novel transgenic mouse lines with affinity tags inserted into the endogenous SMAD1 and SMAD5 loci (Smad1HA/HA and Smad5PA/PA). By profiling the genome-wide distribution of SMAD1, SMAD5, and PR in the mouse uterus, we demonstrated the unique and shared roles of SMAD1 and SMAD5 during the window of implantation. We also showed the presence of a conserved SMAD1, SMAD5, and PR genomic binding signature in the uterus during early pregnancy. To functionally characterize the translational aspects of our findings, we demonstrated that SMAD1/5 knockdown in human endometrial stromal cells suppressed expressions of canonical decidual markers (IGFBP1, PRL, FOXO1) and PR-responsive genes (RORB, KLF15). Here, our studies provide novel tools to study BMP signaling pathways and highlight the fundamental roles of SMAD1/5 in mediating both BMP signaling pathways and the transcriptional response to progesterone (P4) during early pregnancy.
The cryo-EM structure of ASK1 reveals an asymmetric architecture allosterically modulated by TRX1

Published: March 2024

Apoptosis signal-regulating kinase 1 (ASK1) is a crucial stress sensor, directing cells toward apoptosis, differentiation, and senescence via the p38 and JNK signaling pathways. ASK1 dysregulation has been associated with cancer and inflammatory, cardiovascular, and neurodegenerative diseases, among others. However, our limited knowledge of the underlying structural mechanism of ASK1 regulation hampers our ability to target this member of the MAP3K protein family towards developing therapeutic interventions for these disorders. Nevertheless, as a multidomain Ser/Thr protein kinase, ASK1 is regulated by a complex mechanism involving dimerization and interactions with several other proteins, including thioredoxin 1 (TRX1). Thus, the present study aims at structurally characterizing ASK1 and its complex with TRX1 using several biophysical techniques. As shown by cryo-EM analysis, in a state close to its active form, ASK1 is a compact and asymmetric dimer, which enables extensive interdomain and interchain interactions. These interactions stabilize the active conformation of the ASK1 kinase domain. In turn, TRX1 functions as a negative allosteric effector of ASK1, modifying the structure of the TRX1-binding domain and changing its interaction with the tetratricopeptide repeats domain. Consequently, TRX1 reduces access to the activation segment of the kinase domain. Overall, our findings not only clarify the role of ASK1 dimerization and inter-domain contacts but also provide key mechanistic insights into its regulation, thereby highlighting the potential of ASK1 protein-protein interactions as targets for anti-inflammatory therapy.
YOLOv8s-CGF: a lightweight model for wheat ear Fusarium head blight detection
Authors: Yang Chengkai , Sun Xiaoyun , Wang Jian , Lv Haiyan , Dong Ping , Xi Lei , Shi Lei
Published: March 2024

Fusarium head blight (FHB) is a destructive disease that affects wheat production. Detecting FHB accurately and rapidly is crucial for improving wheat yield. Traditional models are difficult to apply to mobile devices due to large parameters, high computation, and resource requirements. Therefore, this article proposes a lightweight detection method based on an improved YOLOv8s to facilitate the rapid deployment of the model on mobile terminals and improve the detection efficiency of wheat FHB. The proposed method introduced a C-FasterNet module, which replaced the C2f module in the backbone network. It helps reduce the number of parameters and the computational volume of the model. Additionally, the Conv in the backbone network is replaced with GhostConv, further reducing parameters and computation without significantly affecting detection accuracy. Thirdly, the introduction of the Focal CIoU loss function reduces the impact of sample imbalance on the detection results and accelerates the model convergence. Lastly, the large target detection head was removed from the model for lightweight. The experimental results show that the size of the improved model (YOLOv8s-CGF) is only 11.7 M, which accounts for 52.0% of the original model (YOLOv8s). The number of parameters is only 5.7 × 106 M, equivalent to 51.4% of the original model. The computational volume is only 21.1 GFLOPs, representing 74.3% of the original model. Moreover, the mean average precision (mAP@0.5) of the model is 99.492%, which is 0.003% higher than the original model, and the mAP@0.5:0.95 is 0.269% higher than the original model. Compared to other YOLO models, the improved lightweight model not only achieved the highest detection precision but also significantly reduced the number of parameters and model size. This provides a valuable reference for FHB detection in wheat ears and deployment on mobile terminals in field environments.
Changes in red blood cell parameters during incremental exercise in highly trained athletes of different sport specializations

Published: March 2024

Background

During physical exercise, the level of hematological parameters change depending on the intensity and duration of exercise and the individual’s physical fitness. Research results, based on samples taken before and after exercise, suggest that hematological parameters increase during incremental exercise. However, there is no data confirming this beyond any doubt. This study examined how red blood cell (RBC) parameters change during the same standard physical exertion in athletes representing different physiological training profiles determined by sport discipline.

Methods

The study included 39 highly trained male members of national teams: 13 futsal players, 12 sprinters, and 14 triathletes. We used multiple blood sampling to determine RBC, hemoglobin (Hb), hematocrit value (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red blood cell distribution width (RDW) before, during (every 3 min), and after (5, 10, 15, 20, and 30 min) an incremental treadmill exercise test until exhaustion.

Results

There were no significant exercise-induced differences in RBC parameters between athletic groups. No significant changes were recorded in RBC parameters during the low-intensity phase of exercise. RBC, Hb, and Hct increased significantly during incremental physical exercise, and rapidly returned to resting values upon test termination.

Conclusions

The general pattern of exercise-induced changes in RBC parameters is universal regardless of the athlete’s physiological profile. The changes in RBC parameters are proportional to the intensity of exercise during the progressive test. The increase in hemoglobin concentration associated with the intensity of exercise is most likely an adaptation to the greater demand of tissues, mainly skeletal muscles, for oxygen.
The contribution of estimated dead space fraction to mortality prediction in patients with chronic obstructive pulmonary disease—a new proposal
Authors: Chuang Ming-Lung , Wang Yu Hsun , Lin I-Feng
Published: March 2024

Background

Mortality due to chronic obstructive pulmonary disease (COPD) is increasing. However, dead space fractions at rest (VD/VTrest) and peak exercise (VD/VTpeak) and variables affecting survival have not been evaluated. This study aimed to investigate these issues.

Methods

This retrospective observational cohort study was conducted from 2010–2020. Patients with COPD who smoked, met the Global Initiatives for Chronic Lung Diseases (GOLD) criteria, had available demographic, complete lung function test (CLFT), medication, acute exacerbation of COPD (AECOPD), Charlson Comorbidity Index, and survival data were enrolled. VD/VTrest and VD/VTpeak were estimated (estVD/VTrest and estVD/VTpeak). Univariate and multivariable Cox regression with stepwise variable selection were performed to estimate hazard ratios of all-cause mortality.

Results

Overall, 14,910 patients with COPD were obtained from the hospital database, and 456 were analyzed after excluding those without CLFT or meeting the lung function criteria during the follow-up period (median (IQR) 597 (331–934.5) days). Of the 456 subjects, 81% had GOLD stages 2 and 3, highly elevated dead space fractions, mild air-trapping and diffusion impairment. The hospitalized AECOPD rate was 0.60 ± 2.84/person/year. Forty-eight subjects (10.5%) died, including 30 with advanced cancer. The incidence density of death was 6.03 per 100 person-years. The crude risk factors for mortality were elevated estVD/VTrest, estVD/VTpeak, ≥2 hospitalizations for AECOPD, advanced age, body mass index (BMI) <18.5 kg/m2, and cancer (hazard ratios (95% C.I.) from 1.03 [1.00–1.06] to 5.45 [3.04–9.79]). The protective factors were high peak expiratory flow%, adjusted diffusing capacity%, alveolar volume%, and BMI 24–26.9 kg/m2. In stepwise Cox regression analysis, after adjusting for all selected factors except cancer, estVD/VTrest and BMI <18.5 kg/m2 were risk factors, whereas BMI 24–26.9 kg/m2 was protective. Cancer was the main cause of all-cause mortality in this study; however, estVD/VTrest and BMI were independent prognostic factors for COPD after excluding cancer.

Conclusions

The predictive formula for dead space fraction enables the estimation of VD/VTrest, and the mortality probability formula facilitates the estimation of COPD mortality. However, the clinical implications should be approached with caution until these formulas have been validated.

Spiritual Counseling and Guidance in the Process of Preventing and Rehabilitating Juvenile Delinquency: A Research on the Views of Guidance Teachers/Psychological Counselors*
Authors: DEMİREL Hüseyin , ÇINAR Fatih
Published: March 2024

In this study, it was aimed to determine the views and approaches of guidance teachers/psychological counselors (GTPC) about spiritual counseling and guidance (SCG) in preventing and improving juvenile delinquency in schools. Qualitative
research method was used in the study. Semi-structured interview technique was used to obtain the data. The sample of the study consisted of 30 volunteer counseling and guidance teachers working in state high schools affiliated
to the Ministry of National Education in Isparta center and districts. Content analysis was used to analyze the data. At the end of the research, it was determined that GTPC mostly encounter legal crimes such as violence, abuse,
addiction, bullying in the institutions where they work and that they carry out preventive studies, intervention studies and improvement studies for juvenile delinquency. In addition, the findings of the study also included the
participants' approaches to SCG in preventing juvenile delinquency. Accordingly, it was determined that most of the interviewed teachers felt the need for spiritual comfort in the face of the negativities they encountered and that
religious beliefs could be effective in the process of coping with the negativities encountered. In addition, it was observed that most of the participants had an approach that spirituality can have positive effects in preventing
juvenile delinquency and that psychotherapy techniques and spirituality can be used together. In addition, it was determined that GTPC had the opinion that spiritual counseling education should be included in undergraduate education.
One of the important findings of the study was that the majority of the participants, who expressed positive opinions in many questions about SCG, expressed negative opinions about the establishment of SCG units in schools and
the appointment of SCG staff. It is thought that the findings of the study will contribute to counseling and guidance counseling, SCG and other related fields.

İnsanın bilişsel/düşünsel inşa edimi dahil olmak üzere yapmak istediği herhangi bir fiili gerçekleştirdiği yetilerle ilgili Kur’an’da geçen nefs, kuvvet, istitâat, tesviye, sûret, uzn, sem‘, fıkh, va‘y, tezkire ve ‘akl gibi bir dizi
kelimenin semantik analizi bu çalışmanın konusunu oluşturmaktadır. Bir edimin/fiilin ortaya çıkması için araç mesabesinde bulunan yetilerin ve bir benlik hâli olarak değerlendirilebilecek bu yetilere sahiplik durumunun hangi kavramlar
üzerinden ifadelendirildiği; sahip olunan yetiler aracılığıyla icra edilen inşa ediminin ve yanı sıra gerçekleştirilen eylemlerin karakter yapısı ve süreci; bu inşa süreci sonucunda ortaya çıkan ve aslında tüm süreci yöneten bir
hedef ürün statüsündeki yapıların hangi kavramlarla dile getirildiği araştırmanın alt başlıklarını oluşturmaktadır. Yetiler aracılığıyla bu nihai ürüne ulaşma/soyutlama sürecinin ‘ilk aşamasını’ oluşturan kavramlar konusunda da
Kur’an’da önemli bir kelime dağarcığı geçmektedir. Ancak Kur’an’ın içinde doğduğu kültürün sözlü bir kültür olması, inşa sırasında yeti ve malzeme tercihinde önemli bir rol oynamış ve onun karakterini belirlemiştir. Bu sebeple
çalışmada yeti ve malzeme olarak ön plana çıktığı düşünülen kavramlar odağa alınmıştır. Bir soyutlama edimi olarak değerlendirilebilecek inşa sürecinde bu yeti ve malzemelerin ifadesi olan sözcüklerin nasıl geçirgen ve çift anlamlı
bir karakterde kullanıldığı betimlenmeye çalışılmıştır. Kelimelerin arasındaki bağın inşası sürecinde, semantik bilimin yöntemsel rehberliği takip edilmiştir. Günümüzde bilişsel psikoloji veya bilişsel bilimler altında tetkik edilen
bu yetilerin Kur’an bağlamında analizi ve bu yetilere Kur’an’ın kendine özgü yaklaşımının ortaya konulması, yetiler bütünü yeni bir özne inşasının soruşturulmasında ufuk açıcı işlevler sağlayabilir. Sonuç olarak analiz edilen kelimelerin
saf duyusal bir girdiden ziyade düşünsel bir anlamı içerecek şekilde, geçirgen bir karakterde kullanıldığı; bu aralıkta duyusal girdinin, aynı şey olarak, düşünseli kendi üzerinden kurduğu; Kur’an’ın, bu açıdan bakıldığında, idraki
aşan aslın duyu formundaki mekânı olarak kendini bir hatırlatım/tezkire şeklinde takdim ettiği; kelimelerin sözel niteliği korunmakla birlikte içeriğinin semantik olarak değiştirildiği gözlenmiştir. Ayrıca Allah ile insan arasındaki
temel analoji noktalarından birinin yetkinlik kavramı üzerinden gerçekleştirildiği ve İslam’ın uluhiyet anlayışının bu kavram üzerine inşa edildiği ulaşılan bulgulardandır.

Aquaponics is an emerging sustainable food production technique where waste from fish culture is used as a source of nutrients for crops grown in hydroponics system. The present study was conducted at the Agriculture Research and Development Center, Sita Eliya, Nuwara Eliya, Sri Lanka during November 2015 to January 2016, to compare the yield of lettuce (Lactuca sativa L.) grown in hydroponics using fish effluents and inorganic fertilizer. The experiment was laid in a Completely Randomized Design with 5 treatments and 4 replicates. The different nutrient solutions used as the treatments of this experiment were water (T1), Albert’s solution (T2), Catla waste water (T3), Common Carp waste water (T4) and Tilapia waste water (T5). Each nutrient solution was tested for its nutrient composition, temperature, pH and electrical conductivity throughout the experimental period. The plant growth and yield parameters measured were plant height (cm), number of leaves, canopy diameter (cm), root length (cm), fresh weight of plant, leaves and roots (g), dry weight of leaves and roots (g) and, yield (ton/ha). The fish related parameters measured were body weight (g), initial and final stocking density (g/m3) and the mortality percentage. The results showed that T2 stood out (p<0.05) with the highest plant height (12.27cm), canopy diameter (14.80cm), number of leaves (12) and root length (15.04cm), exhibiting a vigorous growth compared to the other treatments. A remarkable yield and shoot and root weight (fresh and dry) were also shown by T2 over the other treatments. Fish waste water in T3, T4 and T5 did not fulfill the nutrient requirement of lettuce due to the limited nutrients; nitrogen, phosphorus and potassium) produced by fingerlings. Therefore, these fish waste solutions need to be improved by increasing the feed quality and selecting fish within a suitable age range in order to obtain a yield comparable to T2, which is the commercially available Albert’s solution.

Published: March 2024

Sand production in oil wells is a significant challenge that negatively impacts productivity  and compromise equipment integrity. This study explores the application of Optimized Support Vector Machine (SVM) binary classification algorithm to predict the onset of sand production in oil wells. A dataset from 63 oil wells was utilized, and class labels were determined based on the bulk and shear modulus product.  The model development incorporated geological and mechanical parameters that could influence sand detachment such as: Young’s modulus, Poisson’s ratio, minimum and maximum horizontal stresses, overburden pressure, pore pressure, depth, fracture gradient, and formation strength. Instances above the threshold of 8E+11 were classified as indicative of no sand production, while those below were considered potential sand production scenarios. The SVM model demonstrated remarkable accuracy in predicting sand production onset, trained and tested rigorously with field data. The model's accuracy was evaluated  using statistical parameters, such as: accuracy (ACC), sensitivity (SE), specificity (SP), and Matthew's Correlation Coefficient (MCC). From the results, the model achieved a score of 1 across   all parameters, indicating high reliability and accuracy in sand production prediction. The practical implications of this model are significant, offering assistance to completion engineers in making proactive decisions regarding sand control strategies. Furthermore, the integration of this model into oil and gas industry processes can optimize operational efficiency by foreseeing potential sand production events, hence, preventing production impairment and ensuring loss prevention.

Published: March 2024

The study presents a comprehensive structural integrity assessment of inverted umbrella rainwater harvesting systems through an in-depth analysis conducted using the STAAD-PRO software. The inverted umbrella design, increasingly employed for rainwater harvesting in various settings, necessitates a rigorous examination of its structural performance to ensure reliability and safety. The study employs STAAD-PRO environment to evaluate the load-bearing capacities, stress distributions, and deformations exhibited by the inverted umbrella structures. This study contributes to the broader field of structural engineering by establishing a methodology for utilizing STAAD-PRO in the evaluation of unconventional structures such as inverted umbrella rainwater harvesting systems. Different kinds of live and dead loads acting on the structure was estimated and an emphasis is placed on understanding the dynamic interactions between the system components and the forces imposed by environmental factors, including live and dead loads and seismic activities. Wind load.
The results of the STAAD-PRO analysis offer valuable insights into the structural behavior of the inverted umbrella rainwater harvesting systems under diverse loading conditions. By assessing critical points such as nodes, connections, and supporting elements, the study aims to identify potential vulnerabilities and proposes design modifications to enhance overall structural robustness. Total dead load acting on the structure was found as 2.88kN. The maximum and minimum force experienced by the structure in X, Y and Z direction was found as (2.33kN and 1.37N), (65.12N and 1.37N) and (261.15N and 6.02N) respectively. The structure was also found stable against bending, shear and tensile strength with utility ratio of less than 1. Ultimately, this investigation strives to foster the adoption of reliable and resilient inverted umbrella rainwater harvesting systems, advancing the integration of innovative engineering solutions into sustainable water resource practices.

Aim: Lifelong monitoring is essential to detect aorta-related complications. Yet, patient non-compliance with surveillance programs poses a significant obstacle. We explored reasons for adherence by engaging in clear, patient-centred communication and analyzed factors contributing to non-compliance. Material and Methods: In 2019, our clinic conducted elective EVAR procedures on 50 patients. They were informed of annual surveillance, including hospital visits, starting with a first-month appointment post-discharge. Patients with no or only one follow-up were deemed non-compliant, while two to three follow-ups indicated moderate compliance, and four to seven follow-ups qualified as high compliance. We recorded each patient's age, education level and demographics. We retrospectively assessed the factors on their compliance level as our first outcome. The second was to explore whether the survey could enlighten any reasons from the patient's perspective. Results: The average age of our cohort was 68.8±8.45 years, with only three females. Non-attendance at follow-ups was observed in 8 patients (16%). Seventy percent (35 patients) complied with at least two appointments. Residing in the same city markedly increased compliance by 20 times (p<0.001). Older age appeared to influence compliance positively, on the borderline significantly (p=0.057). The primary motivation for attendance was adherence to doctor recommendations (n=14), while the predominant reason for non-attendance was patients’ feeling well (n=29). Notably, patients with lower compliance than predicted more frequently cited COVID-19 as a deterrent (p=0.02). Conclusion: Residence within the same city positively influences follow-up compliance. The national databases might be helpful tools for enhancing the surveillance anywhere the patients live. The existing hypotheses by healthcare professionals about patient follow-up compliance are only partially corroborated. Incorporating the patient's perspective into these models may be helpful in comprehensively understanding the underlying factors.
Error feedback and the acquisition of geographical representations
Authors: Guzmán‐Muñoz Francisco J. , Johnson Addie
Published: October 2007

Three training conditions were compared in a task of learning locations of cities on a map: One in which participants could avoid errors by searching for the name of the correct city, and two others in which either immediate feedback after each response or delayed feedback after all responses had been made was given. Learners who received feedback only after placing all the cities on the map performed more poorly overall during training but outperformed the other two groups in both immediate and delayed tests. This advantage is interpreted as evidence of differential development of relational knowledge and application of cognitive effort across training conditions. Copyright © 2007 John Wiley & Sons, Ltd.

Published: October 2007

In this paper we describe the use of combinatorial vapor deposition techniques for the optimization of blue organic light emitting diodes (OLEDs). In these devices the star shaped molecule 1 with a triphenylamine core and three fluorene side groups serves as hole transport and emitting layer. Compound 2 with a much lower lying HOMO and a larger bandgap is used as hole blocking layer. Using combinatorial vapor deposition 42 OLEDs with thickness gradients of both the hole transport and the hole blocking layer have been simultaneously prepared on one substrate. The physical characterization of the devices clearly shows that a hole blocking layer of the star shaped molecule 2 is necessary in order to obtain pure blue emission with CIE coordinates of x = 0.15 and y = 0.15. A thickness of only 5 nm of the blocking layer is sufficient, and with increasing layer thickness the brightness of the blue devices drops. The blue devices exhibit a brightness of 400 cd m–2 and a luminous efficiency of 2 cd A–1. The thickness variations of both the hole transport and the hole blocking layer have been made in one combinatorial evaporation experiment on a single substrate using a set of movable masks. This demonstrates how efficient combinatorial methods can be used for the development of OLEDs.
Red–Yellow Fluorescence Patterning of a Polymer Film Containing Phthalimido Carbamate Groups
Authors: Chae K. H. , Kim Y. H.
Published: October 2007

Bicolor fluorescent micro‐patterns in the polymer film are prepared through the use of a new group of photobase generator containing phthalimido carbamate groups. The photobase generation from phthalimide carbamates is studied by examining the changes in pH, fluorescence intensity, and photo‐crosslinking of poly(glycidyl methacrylate). The product analysis of a model compound indicates that amine groups are produced from the photolytic cleavage of the C–N bond of the phthalimide carbamate groups. A copolymer containing phthalimide carbamate groups is applied to a bicolor fluorescent imaging material. Red‐yellow fluorescent micropatterns are obtained by treating the copolymer film, which is irradiated with 254 nm UV light through a photomask, with fluorescamine and rhodamine, consecutively. Various colored fluorescent micropatterns – green, red, or red‐yellow, are obtained on a single polymer film by varying the excitation wavelength.
Rational Design of Supramolecular Conjugated Polymers Displaying Unusual Colorimetric Stability upon Thermal Stress

Published: October 2007

The colorimetric stability upon thermal stress of a series of conjugated polymer supramolecules prepared from 10,12‐docosadiyndioic acid (DCDDA)‐derived diacetylene monomers has been explored. Polydiacetylenes obtained from DCDDA‐bis‐mBzA 3, containing m‐carboxyphenylanilido groups at the both ends of the monomer, were observed to be highly colorimetrically stable upon thermal stimulation. The blue color of a solution containing these polydiacetylene vesicles remains unchanged even when the vesicles were subjected to boiling water. The unusual colorimetric stability is further demonstrated by the observation that blue color persists until vesicles in ethylene glycol are heated to 140 °C. The nature of this unusual thermal stability was elucidated by using polydiacetylene supramolecules, prepared from analogs of DCDDA‐bis‐mBzA 3. The presence of internal amide groups as well as aromatic interactions was found to be essential for the high colorimetric stability of the polydiacetylene supramolecules.

Published: October 2007

Mesoporous aluminosilicate (MAS) was synthesized by hydrothermal method with zeolite NaY as precursor and CTMAB (cetyltrimethylammonium bromide) as structure directing agent. Desulfurization adsorbents were characterized with XRD, BET, FTIR and NH3‐TPD. FTIR results showed that Lewis acid sites act as adsorption centers for dibenzothiophene (DBT) molecules. The adsorption desulfurization ability of MAS was studied in model and hydrotreated diesel. For model oil containing 10mmol/L DBT, the adsorption capacity of adsorbents is NaY > MAS > MCM‐41. For hydrotreated diesel, MAS shows the largest adsorption capacity, MCM‐41 the second, and NaY shows the least adsorption capacity. The improvement of desulfurization ability of improvement of MAS by Cu(I) is more significant than that of MCM‐41. The physicochemical properties of fuels, such as viscosity and aromatics concentration had great influence on the desulfurization property of adsorbents. © 2007 American Institute of Chemical Engineers AIChE J, 2007
