ГЕОЛОГИЯЛЫҚ КАРТАЛАРДАҒЫ ГЕОДИНАМИКАЛЫҚ ПРОЦЕСТЕРДІҢ МӘНІН КӨРСЕТУ МӘСЕЛЕЛЕРІ

Abstract. In connection with the transition to a new paradigm in geology offered by "Lithospheric plate tectonics", it became known that it is difficult to show the geological features of complex dislocated layered structures on geological maps, because the geological significance of such structures is the result of the horizontal movement of matter (geological formations) in time and space and the attributes of these formations in the current erosion section. combination, and the map sheet itself is ultimately a static sheet of paper. This situation requires the development of qualitative new methods and methodology for mapping highly dislocated tectonic structures, a vivid example of which is called "Pre-Late Paleozoic Ophiolitic Zones of Kazakhstan". ", it turns out that it is difficult to display the geological features of complex folded structures on geological maps, since the geological essence of such structures is the result of the horizontal movement of matter (geological formations) in time and space with the subsequent combination of the attributes of these formations on the modern erosion section, while the sheet of the map itself It is, after all, a static sheet of paper. This circumstance requires the development of qualitatively new methods and methodologies for mapping highly dislocated tectonic structures, a striking example of which are the so-called "Late Precambrian-Paleozoic ophiolite zones of Kazakhstan".

Physics informed neural networks reveal valid models for reactive diffusion of volatiles through paper

Predictive models for the transport of volatile organic compounds in paper need to consider the complex interplay of diffusion, adsorption, desorption, or chemical reactions. The relative importance of each of these processes is determined by the polarity of the volatile. Hence, it is challenging to pick a valid theoretical model that correctly predicts transport regardless of the polarity. Here, physics-informed neural networks (PINNs) assess which of five different models correctly describe transport of DMSO as polar and n-tetradecane as apolar model compound: (i) a pseudo first-order adsorption model for an irreversible sorption process, (ii) a first-order kinetics model allowing reversible sorption, (iii) a second-order model with a reversible process, and an effective diffusion model accounting for a constant (iv) and for a variable effective diffusivity (v). Each tested model is given as set of partial differential equations (PDE). Considering the model under testing and experimentally obtained spatially and temporally resolved concentration profiles through stacks of paper sheets, PINNs predict concentration of the volatiles and associated material constants such as sorption constants and effective diffusion coefficients by solving the inverse problem. Our PINNs revealed two models, pseudo first-order sorption and second-order reversible sorption, that correctly predict concentration profiles and polarity-driven differences in sorption times. While a PINN-based picking of valid transport models has important implications for the development of effective methods for controlling emission of volatiles from paper materials, PINNs represent a versatile mathematical tool to validate or refute the capability of PDE-based theoretical models to describe experimental data.

Discovery-based approach combined with active learning to improve student learning experiences for STEM students

A combination of discovery-based learning (as a novel instructional approach) and Pro-Con Grids (as an active learning activity) is used to improve long-term retention among STEM students. Students in a required Construction Management course were provided with a course lecture prior to in-class sessions. A quiz was used for each lecture to gain insight into students’ understanding and to evaluate the effectiveness of the learning method. During the in-class sessions, a blank sheet of paper was handed out to students to make a list of the pros and cons/advantages and disadvantages of the topics covered in the lecture. Once the pro-con grid was complete, the students were directed to share their documents with the instructor. This was followed by a summary of key concepts and then a review of the correct answers. Data was collected for this study in two forms; through a student survey and grades. The results showed that discovery-based learning could convince students to find and use information rather than memorizing and repeating concepts and facilitate effective group work. In addition, the grade comparisons for three semesters indicated that the higher the use of discovery learning during the course the higher the course grades were found to be

Nanofibers isolated from unbleached date palm residues pulps and their use for paper coating

In the current work, cellulose nanofibers (CNF) were isolated from unbleached kraft pulps of date palm fruit stalks (DPFS) and date palm rachis (DPR) residues by ultrafine grinding. The isolated CNF were characterized by high-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD), zeta potential measurement, tensile strength properties, contact angle, as well as oil-proof testing. The CNF were applied as a coating material for cardboard paper sheets made from unbleached kraft DPFS and DPR pulps. The results showed that CNF from DPFS and DPR had close dimensions (4–14 nm in width and several microns in length) but their zeta potential was different (−44.65 eV and −51.46 eV for CNF from DPFS and DPR pulps, respectively), as well as their crystallinity (79.4% and 75.5% for CNF from DPFS and DPR pulps, respectively). CNF films from DPFS had tensile stress and Young's modulus of 113.3 MPa and 3.81 GPa, respectively, while those from DPR had tensile stress and Young's modulus of 71.0 MPa and 2.93 GPa, respectively. Films from DPFS CNF showed lower hydrophilicity than that from DPR, nevertheless excellent oil-proof property was obtained in both kinds of films. Coating of cardboard sheets prepared from unbleached kraft DPFS and DPR pulps with CNF layer of about 7-µm thickness resulted in significant changes in some physical properties of paper sheets, such as decreasing their air permeability, water vapor transmission rate, and water absorption; both kinds of CNF imparted paper sheets good oil-proof properties. CNF coating also imparted paper sheets remarkable wet tensile strength properties. The results showed the feasibility of utilizing date palm wastes in producing CNF films with distinct properties from low-cost unbleached kraft pulp, as well as using these CNF as a multi-functional coating material in papermaking industry.

The use of Thermography to Determine the Boundary Conditions of Heat Exchange on The Inner Surfaces of Translucent Enclosing Structures

The paper presents an approach to determining the boundary conditions of heat transfer (heat transfer coefficients) on the inner surfaces of translucent enclosing structures using thermal imaging data. To implement this approach, it is necessary to use additional equipment in the form of sheets of paper. A sheet of paper is installed close to and perpendicular to the investigated surface of the structure. At the same time, the profile of the sheet of paper exactly repeats the geometry of the surface under study. Based on the results of thermal imaging, thermograms and temperature graphs are constructed on characteristic areas of the inner surface of the translucent enclosing structure. They are used to determine the thickness of the boundary layer of air adjacent to the inner surface of the translucent enclosing structure. These data are used later to calculate the heat transfer coefficient at the inner surface of these structures. The presented approach was implemented in the course of field studies of heat transfer conditions at the internal surfaces of four PVC windows.

Abstract C112: Improving breast cancer screening disparities through A3 problem solving: Design of a quality improvement initiative

Abstract Introduction: Extensive research studies on breast cancer disparities have had limited impact on reducing breast cancer disparities. Quality improvement initiatives use data-driven, rigorous approaches to plan, execute, and study the delivery of healthcare services. There have been limited studies using quality improvement methods to address health disparities. The purpose of our study was to describe the design of a quality improvement initiative to address breast cancer disparities using the A3 problem solving method. Methods: A3 problem solving method was used to reduce breast cancer screening disparities. The A3 method is a quality improvement tool used to identify problems, organize and synthesize data, and propose solutions to achieve goals (summarized on one side of a sheet of paper). A3 methods are outlined by the FOCUS-PDCA acronym: F - Find process to improve, O - Organize team of stakeholders, C - Clarify current state, U - Understand sources of variation that contribute to the problem, S - Select change ideas, P - Plan and do the improvement, C - Check the results, A - Act. Quantitative data was derived from the electronic medical record. Qualitative data was derived from divergent thinking exercises asking participants from diverse standing urban stakeholder groups about barriers to cancer screening. Results: Design of the A3 problem solving process was conducted between November 2022 until May 2023 yielding the following FOCUS-PDCA design and initial results. F - Increase the percentage of patients who have undergone mammography screening within the last two years. O - Team includes representative leaders from primary care, community health, ambulatory operations, diversity, equity, and inclusion, radiology, breast center, population health, information services, and federally qualified health centers. C and U - Quantitative data collection revealed that 74% of 37,509 eligible patients (women between 50-74 years old) received a mammogram within the last two years (75% White, 58% Black, 67% Asian, 60% American Indian, 64% Hispanic). Divergent thinking exercises revealed the following root causes for mammography screening disparities: patients don’t know they are due, transportation issues, barriers to scheduling, access to mammography facilities, financial concerns, and fears about returning to clinics during COVID-19. S - Process improvements included multilingual and modality reminders, marketing campaigns, transportation vouchers, co-location of screening centers with federally qualified health centers, expanded access to mammography screening facilities, educational activities for primary care physicians, participation in community events, equity-focused review of screening guidelines. PDCA - Based on selected improvements, changes in breast cancer screening percentages will be displayed using run charts until December 2024, stratified by race and ethnicity. Conclusion: A3 problem solving tools represent structured, scientifically rigorous approaches that cancer centers can use to reduce screening disparities. Citation Format: Nia Foster, Arissa J.

The effect of carbonyl components of printing substrates on the durability of UV thermochromic prints

Special effects on a printed product can increase consumer’s interest in a product and therefore lead to higher revenues in consumer industries. For that purpose, graphic industry introduced various technologies and materials that would have such an effect and enhance consumer-goods interaction. One of those solutions is thermochromic printing. Although bringing added value, thermochromic inks have some challenges in application due to their higher sensitivity, especially when exposed to UV light. Therefore, the goal of this work is to determine whether amount of the UV radiation during curing of UV thermochromic prints, as well as exposure after printing would degrade the thermochromic print on various substrates. UV thermochromic prints were made on three different paper printing substrates using the screen printing method and dried in a laboratory controlled unit. Synthetic paper, recycled paper containing 100 % recycled cellulose fibers and bulky voluminous paper were used as printing substrates. During the UV curing of the ink, no photooxidation of the prints occurred. Additional exposure of the prints to UV radiation (after the ink has hardened) leads to their photooxidative degradation, i.e., a change in the initial color. The obtained colour difference (ΔE) is increasing with the increase of the irradiation amount. The highest colour difference is on the synthetic paper while prints on two other substrates are more resistant to UV light. A print on synthetic paper photooxidizes the fastest due to the presence of most carbonyl groups in it. Generated free radicals promote the instability of prints on synthetic paper. Research has proven that when using synthetic paper or substrates with similar characteristics, care should be taken to accurately determine the amount of UV energy required for curing in order to prevent photodegradation of the ink. The results also show that to explain any degradation of prints, the chemical components of the paper needs to be taken into account, which is rarely done.

Decoding acoustic tone from vibrating paper using a smartphone

The availability of low-cost cameras and the development of computer-vision methods have driven the demand of vision-based technology in real-world applications. In this study, we examine the effect of sound on a thin sheet of paper placed 5 cm away from the sound source (speaker). Tiny movements on the paper induced due to the sound generated using speaker were recorded in the video. The slow-motion feature of the smartphone camera is used to observe the sound vibrations. The video was recorded at rate of approximately 240 frames per second and pure tone with frequency varying from 50 Hz to 110 Hz has been detected on the piece of paper. A computer vision method employing Harris-corner detection technique is used to detect the feature movement caused with respect to the sound played. It also opens the possibility of finding the frequency of the noise generated due to nearby sound sources by observing the movements on the membrane, curtains, plant leaves, etc. Further it serves as a basis to work in the direction of extracting the sound information using the vision technique employing simple smartphone.

A Versatile Shaping Method of Very-High Loading Porous Solids Paper Adsorbent Composites.

Owing to their high porosity and tunability, porous solids such as metal-organic frameworks (MOFs), zeolites, or activated carbons (ACs) are of great interest in the fields of air purification, gas separation, and catalysis, among others. Nonetheless, these materials are usually synthetized as powders and need to be shaped in a more practical way that does not modify their intrinsic property (i.e., porosity). Elaborating porous, freestanding and flexible sheets is a relevant shaping strategy. However, when high loadings (>70wt.%) are achieved the mechanical properties are challenged. A new straightforward and green method involving the combination softwood bleached kraft pulp fibers (S) and nano-fibrillated cellulose (NFC) is reported, where S provides flexibility while NFC acts as a micro-structuring and mechanical reinforcement agent to form high loadings porous solids paper sheets (>70wt.%). The composite has unobstructed porosity and good mechanical strength. The sheets prepared with various fillers (MOFs, ACs, and zeolites) can be rolled, handled, and adapted to different uses, such as air purification. As an example of potential application, a MOF paper composite has been considered for the capture of polar volatile organic compounds exhibiting better performance than beads and granules.

Caronia Glaucoma Card Versus Amsler Grid for Monitoring Patients With Advanced Glaucoma.

Caronia Glaucoma Card (CGC) design incorporates a vertical and horizontal line and seven concentric circles corresponding to 1 o arc at normal reading distance. The study showed that the CGC is preferred by study patients compared to Amsler Grid and can detect central scotomas. Evaluate patient acceptance and efficacy of the Caronia Glaucoma Card (CGC) in monitoring patients with severe glaucoma. A retrospective study of consecutive patients with severe glaucoma who agreed to monitor their visual function. Patients were given a two-sided sheet of paper. An Amsler grid was printed on one side, and a CGC was printed on the other side. The patient was given verbal and written instructions on how to perform each test. They were asked to use either one or both tests to monitor their visual function on a weekly basis. Upon return, they were asked which test they preferred and if they appreciated or noticed any change in their scotoma. Patient comments were recorded. Sixty-seven patients were given the test card whose reported past ocular history consisted solely of severe glaucoma. Seventeen patients were eventually excluded. Fourteen patients had 1 eye that fulfilled the inclusion criteria for the study, while the other eye was excluded. Eighty-six eyes of fifty patients satisfied the inclusion criteria and were enrolled in the study. Thirty of the patients were male (60%) and 20 were female (40%). The average age was 71.8 +/- 10.7 years. They all carried a diagnosis of severe glaucoma. When asked the question which test design they preferred to use, 30 patients preferred the CGC (60%), while 8 patients preferred the Amsler grid (16%). Twelve patients found no difference between the 2 test designs (24%). [χ 2 (2, 50)=16.480, ρ=0.000]. Five patients noticed a change in their scotoma while using the card (5.8%, 5 of 86 eyes). All were exclusively using the CGC. The CGC is a convenient and inexpensive tool that was able to detect a change in scotoma. It may be helpful to add to the armamentarium to monitor glaucoma and its possible progression in patients with advanced disease.

Material properties and durability of 19th–20th century Tibetan manuscripts

Most currently available research into Tibetan paper focuses on the earliest books from an archaeological perspective. On the other hand, scientific studies of the 19th−20th century Tibetan paper are largely missing, specifically with respect to material properties and paper permanence. To explore these, both conventional and modified methods were applied using reference historic material collection. Material properties such as fibre morphology, paper pH, degree of polymerisation (DP), water and ash contents were investigated. The measurement methods for starch and protein content were explored—and we report on a quantification method for the determination of starch content in paper. The degradation behaviour of Tibetan paper was studied using accelerated degradation experiments at two sets of conditions (80 ˚C, 65% RH and 60 ˚C, 80% RH) for up to 84 days in order to explore the applicability of existing dose-response functions. The results demonstrate that examined 19th−20th century papers used in Tibetan books, were prepared using diverse fibres, similar to traditional Chinese paper. Most of paper sheets presented laminated structures, where starch was used as the predominant glue. The layers within one paper sheet are identical, as evidenced by similar pH and DP values among layers in one sheet. The studied collection of papers tends to have similar properties to modern Chinese paper since most of both types of papers present pH 6.5–8 and DP 1000–2000. The accelerated degradation experiment shows that papers used as writing support in Tibetan books follows the same principle of degradation as western paper has demonstrated, i.e., the rate constants of degradation depend on paper pH, temperature, and relative humidity of the environment. This research expands our understanding of this collection and inform preventive conservation of modern Tibetan manuscripts.

Typha domingensis and Phragmites australis as alternative and sustainable pulp materials for primary paper based packaging

Environmental pollution with plastic waste and deforestation has led to increase research into the development of new natural fibers. Typha domingensis and Phragmites australis was used to make sustainable paper sheet and rigid containers packaging. Characterization of structural, mechanical, barriers, safety and end-of-life properties of Typha paper coated with polyolefins or polylactic acid was performed. Cellulose extraction was done at, 10 % NaOH at 120 °C for 90 min, the cellulose and fibers of these plants were used to produce a paper sheet and trays. The results showed that sheets made from Typha were 100 % recyclable and, showed mechanical properties comparable (5900 MPa) to a commercial Mitsubishi paper (7000 MPa) at parity of grammage. Typha and Reeds trays were permeable to water vapors and oxygen, but resistant to fat. The results LCA analysis showed that Typha trays had an environmental impact three times lower than aluminum trays, the most use in Senegal.

To study the clinical utility of WHO modified and paperless partograph in the management of labour and its outcome

Early detection of abnormal progress of labour and prevention of prolonged labour significantly improves pregnancy outcomes. Partograph is a simple and important tool which can provide a continuous pictorial overview of labour on a single sheet of paper and is essential to monitor labour. (1) To study the progress of labour using WHO modified partograph in terms of alert line and action line and using paperless partograph in terms of alert and action estimated time of delivery and detect any deviation from normal progress of labour. (2) To evaluate the duration of labour, mode of delivery and perinatal outcome in both the groups.It was a prospective observational study which was conducted over a period of 18months on 200 antenatal patients admitted to the Department of Obstetrics and Gynaecology at Christian Medical College and Hospital, Ludhiana. Antenatal patients with singleton term pregnancy with cephalic presentation in active phase of labour were included in the study. The WHO modified partograph was plotted for 100 cases (Group I) and the paperless partograph was recorded for the other group of 100 patients (Group II) and their outcomes were compared. The p value <0.05 was considered to be significant.In our study we noted that the findings were similar in the WHO modified partograph group and the paperless partograph group in terms of duration of labour, progress of labour, mode of delivery and neonatal outcomes with no statistically significant difference between both the groups.Our study concluded that the paperless partograph is as good as the WHO modified partograph in predicting the labour outcomes and identifying labour abnormalities. The paperless partograph does not need graphical representation and therefore can be adopted as an alternative to the WHO modified partograph in busy labour room settings.

Photosensitive cellulosic materials based on a covalently grafted phenosafranin-modified silsesquioxane analog for bactericidal applications

Light-triggered antimicrobial cellulose surfaces were obtained by the immobilization of a photosensitive phenosafranin dye (PSF) in a hybrid organic–inorganic silsesquioxane polymer applied on handsheets prepared from a standard bleached softwood pulp. These coatings were deposited by polycondensation of methyltriethoxysilane and an alkoxysilyl derivative of phenosafranin (TESPSF) obtained by the thiolene addition reaction and coupling of the succinic anhydride derivative with a primary amine group of PSF. TESPSF and coatings were characterized by advanced techniques in terms of chemical structure (1H, 13C, 29Si NMR, MS, ATR-IR), surface properties (SEM, EDX, water contact angles), and optical properties (UV, reflection light intensity, ISO brightness). The light-induced antimicrobial activity of sheets of paper coated with new materials showed the inhibition of the growth of the bacteria Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 8739. The cytotoxicity studies of modified cellulose surfaces were performed using erythrocyte lysis assays under both dark and light conditions exhibited no toxicity on erythrocytes. Thus, the new material did not reveal harmful effects on erythrocytes, regardless of the presence and absence of light.

A Survey on Deep Generative 3D-aware Image Synthesis

Recent years have seen remarkable progress in deep learning powered visual content creation. This includes deep generative 3D-aware image synthesis, which produces high-fidelity images in a 3D-consistent manner while simultaneously capturing compact surfaces of objects from pure image collections without the need for any 3D supervision, thus bridging the gap between 2D imagery and 3D reality. The field of computer vision has been recently captivated by the task of deep generative 3D-aware image synthesis, with hundreds of papers appearing in top-tier journals and conferences over the past few years (mainly the past two years), but there lacks a comprehensive survey of this remarkable and swift progress. Our survey aims to introduce new researchers to this topic, provide a useful reference for related works, and stimulate future research directions through our discussion section. Apart from the presented papers, we aim to constantly update the latest relevant papers along with corresponding implementations at https://weihaox.github.io/3D-aware-Gen .
