The genus Orthoseira (Orthoseiraceae, Bacillariophyta) in Papua New Guinea with the description of two new species

Background and aims – The genus Orthoseira is generally known to be typically aerophilous. Despite the worldwide occurrence of the genus, most of the Orthoseira species seem to have a rather restricted biogeographic distribution, often being part of an endemic diatom flora. During a survey of the aerophilic diatom flora in Papua New Guinea (Karkar Island, Boisa Island), four morphologically distinct Orthoseira taxa have been observed. Material and methods – The morphology of four Orthoseira species was investigated in detail using light microscopy (LM) and scanning electron microscopy (SEM). Key results – The morphology of all four species is discussed and compared to known species worldwide. The main differences between the species include: the presence and shape of linking structures, the number of rows of perforations on the copulae, presence/absence of internal caverns and the external structure of the carinoportulae. Two species, with a unique set of features, are described as new to science: Orthoseira iserentantii sp. nov. and Orthoseira papuensis sp. nov. Conclusions – The observation of four Orthoseira species, including two species new to science, confirms that the diversity of the genus Orthoseira is underestimated.

A Study on the Impact of Environmental Awareness on Sustainable Consumption Behavior in Maternity Wear

With the relaxation of China’s birth policies and the dual independence gained by Chinese women in both mental and economic aspects, maternity wear, as an essential item for pregnant women, has an enormous design space and a growing consumer market, attracting increasing attention from all quarters [1]. However, due to the continuous changes in pregnant womens body shapes and the fact that most women need to continue working and socializing during the early and middle stages of pregnancy [2], maternity wear has a short wearing cycle and rapid turnover [3] leading to the current unsustainable consumption of maternity wear. This study aims to explore the impact of environmental awareness on the sustainable consumption behavior of maternity wear. Specifically, the study objective is to use Grounded Theory to analyze sustainability issues within maternity wear consumption and identify the factors and stages influencing sustainable consumption behavior through online searches for relevant reports and comments. We address 2 research questions. RQ1: How to improve the sustainability of maternity wear to reduce unsustainable consumption? RQ2: How does environmental awareness influence sustainable consumption behavior in maternity wear? This article, based on Grounded Theory, to ensure the timeliness of comments and reports, conducted sample data collection from 2019 to 2022. We conducted searches using keywords such as “sustainable maternity wear,” “ecofriendly maternity wear,” “sustainable fashion,” “maternity wear consumption,” and “postpartum clothing consumption. ” We obtained a total of 1086 relevant articles and materials. After careful screening, we narrowed down our searches and organized 45 feasible textual materials for our study. Through online searches for relevant reports and comments regarding sustainable consumption of maternity wear, it identified consciousness-related influencing factors and three stages of sustainable maternity wear consumption behavior. Furthermore, it proposed reference recommendations for promoting sustainable consumption of maternity wear through management practices. Keywords: environmental awareness, maternity wear, sustainability, consumer behavior, grounded theory
Reasons behind Sleep Deprivation among Adolescents: Evidence from Beijing

Although current studies have examined the association between multiple variables and sleep deprivation among adolescents, such as the use of electronic devices and stress, few studies managed to disassociate the variables and examine the impact of each one on sleep individually. The objective of this study is to examine which factor between the use of electronic devices, workload, stress and basic psychological needs of an individual has the most impact on sleep duration and quality of adolescents. 16 participants volunteered for this research measuring their sleep and deep sleep through commercially available smart band provided. They self-reported the sleep data recorded along with the amount of time spent on electronic devices and schoolwork, and a rating of workload and stress on a scale of 1-10 through a period of 38 days. Participants then completed a Pittsburgh Sleep Quality Index questionnaire and a Self-Determination Theory questionnaire. Results show that stress has the most impact on both sleep duration and quality. The fulfillment of an individual’s psychological needs highly correlates with sleep: the unmet psychological needs directly influence other variables such as stress level which will affect sleep. This research shows inconsistency during data analysis when different method is applied potentially due to time constrain of this research, future research is needed to prove the validity of the finding.
Additives to control mechanical properties and drug delivery of injectable polymeric scaffolds

OF DISSERTATION ADDITIVES TO CONTROL MECHANICAL PROPERTIES AND DRUG DELIVERY OF INJECTABLE POLYMERIC SCAFFOLDS In situ forming implants (ISIs) are popular due to their ease of use and local drug delivery potential, but they suffer from high initial drug burst, and release behavior is tied closely to solvent exchange and polymer properties. Additionally, such systems are traditionally viewed purely as drug delivery devices rather than potential scaffold materials due to their poor mechanical properties and minimal porosity. The aim of this research was to develop an injectable ISI with drug release, mechanical, and microstructural properties controlled by microand nanoparticle additives. First, an injectable ISI was developed with appropriate drug release kinetics for orthopedic applications. Poly(β-amino ester) (PBAE) microparticles were loaded with simvastatin or clodronate, and their loading efficiency and drug retention after washing was quantified. Drug-loaded PBAE microparticles and hydroxyapatite (HA) microparticles were added to a poly(lactic-co-glycolic acid) (PLGA)–based ISI. By loading simvastatin into PBAE microparticles, release was extended from 10 days to 30 days, and burst was reduced from 81% to 39%. Clodronate burst was reduced after addition of HA, but was unaffected by PBAE loading. Scaffold mass and porosity fluctuated as the scaffolds swelled and then degraded over 40 days. Next, the mechanical properties of these composite ISIs were quantified. Both microand nanoparticulate HA as well as PBAE microparticle content were varied. Increasing HA content generally improved compressive strength and modulus, with a plateau occurring at 30% nano-HA. Injectability remained clinically acceptable for up to 10% w/w PBAE microparticles. Ex vivo injections into trabecular bone improved both strength and modulus. Lastly, HA-free ISIs were investigated for drug delivery into the gingiva to treat periodontitis. Doxycycline and simvastatin were co-delivered, with delivery of doxycycline over 1 week accompanied by simvastatin release over 30 days. PBAE-containing ISIs exhibited higher initial and progressive porosity and accessible volume than PBAE-free ISIs over the course of degradation. Additionally, PBAE-containing ISIs provided superior tissue retention within a simulated periodontal pocket. The ISIs investigated here have a wide range of potential applications due to their flexible material and drug release properties, which can be controlled by both the chemistry and concentration of various particulate additives.
In silico analysis of Bacillus stearothermophilus as a bioindicator for sterilizationco analysis of Bacillus stearothermophilus as a bioindicator for sterilization

To kill every kind of viable bacterial cells, sterilization in food and pharmaceutical industries is essential. In this study, bio indicators are used to validate accurate sterility. Bacillus stearothermophilus is used as a reference standard heat stable bio indicator. A 16S ribosomal RNA ribotyping sequence of Bacillus stearothermophilus is compared with different bacterial bioindicators including Bacillus pumilus, Bacillus atrophaeus, Clostridium sporogenes, and Brevundimonas diminuta. Results showed that Bacillus pumilus has the highest percentage (90.88%) similarity with the Geobacillus stearothermophilus followed by the Bacillus atrophaeus (90.84%), and Clostridium sporogenes (85.35%). The Brevundimonas diminuta was the least similar organism having a percentage similarity of 81.71% with the Geobacillus stearothermophilus. Bacterial spores are used as biological indicators for sterilization because they exhibit resistance to chemical and physical sterilization techniques. The protein common in all bacteria under study is Spo0A that make the bacteria heat resistant. The eradication of all these kind of heat resistant spores needs a high temperature which will also kill other viable cells. Keywords: Bacillus stearothermophilus; Bacillus pumilus; Bacillus atrophaeus; Clostridium sporogenes and Brevundimonas diminuta; Spo0A protein.

RASCAL: Calculation of Graph Similarity using Maximum Common Edge Subgraphs

A new graph similarity calculation procedure is introduced for comparing labeled graphs. Given a minimum similarity threshold, the procedure consists of an initial screening process to determine whether it is possible for the measure of similarity between the two graphs to exceed the minimum threshold, followed by a rigorous maximum common edge subgraph (MCES) detection algorithm to compute the exact degree and composition of similarity. The proposed MCES algorithm is based on a maximum clique formulation of the problem and is a significant improvement over other published algorithms. It presents new approaches to both lower and upper bounding as well as vertex selection.
Impact of horizontal diffusion, vertical resolution, microphysics, radiation and cloudiness parametrization schemes on fog forecast in valleys

In December 2004, fog and low stratus were absent from the initial conditions (although there was humidity) and failed to develop during the model forecast resulting in wrong 2m temperature and cloudiness forecast. Various model parametrizations were tested in order to forecast the fog and low stratus using the same initial conditions.
Development of low-cost fly ash bricks

Fly ash is produced in vast quantities as a by-product of the burning of fossil fuels for the thermal generation of electricity. At present 10-15% of the fly ash produced in Australia is utilised in cement manufacturing and concrete industry, with the remaining majority requiring costly disposal processes. Due to growing environmental concerns and the need for cleaner production, the management of fly ash has become an important issue facing the power generation industry. For that reason, many researchers are actively working to find new and improved methods of combating the fly ash waste disposal problem, particularly by establishing its useful and economic utilisation. One such example that is gaining considerable interest in many parts of the world is the utilisation of fly ash in brick manufacturing. This paper examines the potential for using Class F fly ashes from Queensland as major constituents in the manufacture of common residential building bricks. Scaled-down pressed bricks were made by varying proportions of fly ash, sand, hydrated lime, sodium silicate and water. Both fired, oven-dried and air-cured bricks were tested for their properties including compressive strength, tensile strength, water absorption, and durability. In the paper, the test results are analysed and effects of variables discussed. Recommendations and conclusions as to whether or not the fly ash bricks can perform adequately alongside the clay bricks are included.
Geochemical background and threshold for 47 chemical elements in Slovenian topsoil

Geochemical background and threshold values need to be established to identify areas with unusually high concentrations of elements. High concentrations are caused by natural or anthropogenic processes. The <2 mm fraction of 817 collected topsoil (0 – 10 cm) samples at a 5 × 5 km grid on the territory of Slovenia was analysed. Results are used here to establish the geochemical background variation and threshold values, derived statistically from the data set, in order to identify unusually high element concentrations for these elements in the soil samples. Geochemical threshold values were determined following different methods of calculation for (1) whole of Slovenia and (2) for 8 spatial units determined on the base of geological structure, lithology, relief, climate and vegetation. Medians and geochemical thresholds for whole of Slovenia were compared with data for Europe and for southern Europe separately, since large differences in the spatial distribution of many elements are observed between northern and southern Europe. Potentially toxic elements (PTEs), namely As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, and Zn, are of particular interest. Medians of these PTE elements are all higher in Slovenia than in southern Europe. Medians of Pb and Mo are 1.5 times higher and medians of Hg and Cd are even more than 2 times higher in Slovenia. Geochemical thresholds for As, Cr, Co, Ni, Sb and Zn are of similar values in both Slovenia and southern Europe and some lower for Cu and Ni. Up to 1.5 times higher are tresholds in Slovenia for Mo and Pb and more than 2.5 times higher for Cd and Hg. These values were then compared to existing Slovenian soil guideline values for these elements.
Monsoon-induced changes in surface hydrography of the eastern Arabian Sea during the early Pleistocene

Abstract Upper water column dynamics in the eastern Arabian Sea were reconstructed in order to investigate changes in the activity of the South Asian / Indian monsoon during the early Pleistocene (c. 1.5–2.7 Ma). We used planktic foraminiferal assemblage records combined with isotopic (δ18O and δ13C) data, Mg/Ca-based sea surface temperatures and seawater δ18O records to estimate changes in surface water conditions at International Ocean Discovery Program (IODP) Site U1457. Our records indicate two distinct regimes of monsoon-induced changes in upper water structure during the periods c. 1.55–1.65 Ma and c. 1.85–2.7 Ma. We infer that a more stratified upper water column and oligotrophic mixed layer conditions prevailed during the period 1.85–2.7 Ma, which may be due to overall weaker South Asian / Indian winter (NE) and summer (SW) monsoon circulations. The period 1.55–1.65 Ma was characterized by enhanced eutrophication of the mixed layer, which was probably triggered by intensified winter (NE) monsoonal winds. The long-term trend in hydrographic changes during 1.55–1.65 Ma appears to be superimposed by short-term variations, probably reflecting glacial/interglacial changes. We suggest that an intensification of the South Asian / Indian winter monsoon circulation occurred between ∼1.65 Ma and 1.85 Ma, which is most likely due to the development of strong meridional and zonal atmospheric circulations (i.e. Walker Circulation and Hadley Circulation) because of strong equatorial East–West Pacific temperature gradients.
Comparison of kinematics and joint moments calculations for lower limbs during gait using markerless and marker-based motion capture

Objective: This study aimed at quantifying the difference in kinematic and joint moments calculation for lower limbs during gait utilizing a markerless motion system (TsingVA Technology, Beijing, China) in comparison to values estimated using a marker-based motion capture system (Nokov Motion Capture System, Beijing, China). Methods: Sixteen healthy participants were recruited for the study. The kinematic data of the lower limb during walking were acquired simultaneously based on the markerless motion capture system (120 Hz) and the marker-based motion capture system (120 Hz). The ground reaction force was recorded synchronously using a force platform (1,200 Hz). The kinematic and force data were input into Visual3D for inverse dynamics calculations. Results: The difference in the lower limb joint center position between the two systems was the least at the ankle joint in the posterior/anterior direction, with the mean absolute deviation (MAD) of 0.74 cm. The least difference in measuring lower limb angles between the two systems was found in flexion/extension movement, and the greatest difference was found in internal/external rotation movement. The coefficient of multiple correlations (CMC) of the lower limb three joint moments for both systems exceeded or equaled 0.75, except for the ad/abduction of the knee and ankle. All the Root Mean Squared Deviation (RMSD) of the lower limb joint moment are below 18 N·m. Conclusion: The markerless motion capture system and marker-based motion capture system showed a high similarity in kinematics and inverse dynamic calculation for lower limbs during gait in the sagittal plane. However, it should be noted that there is a notable deviation in ad/abduction moments at the knee and ankle.
Impactites of the Mistastin Lake impact structure: Insights into impact ejecta emplacement

The Mistastin Lake impact structure is an intermediate‐size (~28 km apparent crater diameter), complex crater formed ~36 Myr. The original crater has been differentially eroded; however, a subdued terraced rim and distinct central uplift are still observed and impactites are well exposed in three dimensions. The inner portion of the structure is covered by Mistastin Lake and the surrounding area is locally covered by soil/glacial deposits and vegetation. The crystalline target rocks of the Mistastin Lake region are dominated by anorthosite, granodiorite, and quartz monzonite. Previous studies of the Mistastin Lake impactites have primarily focussed on the impact melt rocks. This study further evaluates the entire suite of impactite rocks in terms of their location within the crater structure and emplacement mechanisms. Locally, allochthonous impactite units including impact melt and various types of breccias are distributed around the lake in the terraced rim and are interpreted as proximal ejecta deposits. A multistage model for the origin and emplacement of impact melt rocks and the formation of impact ejecta is proposed for the Mistastin Lake impact structure based on a synthesis of the field and petrographic observations. This model involves the generation of a continuous ballistic ejecta blanket during the excavation stage, followed by the emplacement of melt‐rich, ground‐hugging flows during the terminal stages of crater excavation and the modification stage of crater formation. Impact melt‐bearing breccias—also termed “suevite” at other sites—are present in several distinct settings within the Mistastin Lake structure and likely have more than one formation mechanism.
Incorporating Tumor Edge Information for Fine-Grained BI-RADS Classification of Breast Ultrasound Images

Breast Ultrasound (BUS) imaging is an essential tool for the early detection of breast cancer. The Breast Imaging Reporting and Data System (BI-RADS) in BUS images helps standardize the interpretation and reporting process by categorizing breast tumors into multiple classes, which enables radiologists to make more accurate diagnoses and treatment plans. However, most existing classification methods distinguish only between benign and malignant categories. In addition, features extracted by classic convolutional neural networks tend to be insufficient when subdividing BUS images into fine-grained BI-RADS classes, as they typically do not consider prior knowledge in medical applications, such as foreground shape. To address the above problems, we propose a novel fine-grained BI-RADS classification approach that integrates tumor edges to provide more efficient discriminative features. Firstly, weakly supervised pseudo-label generation: we detect coarse tumor edge regions utilizing a pre-trained PiDiNet and two novel loss functions based on prior knowledge from our dataset. The detected tumor edges are subsequently used as pseudo-labels for the next step. Secondly, co-training a tumor edge detection network and a BI-RADS classification network: edge images generated by the edge detection network are used as weight masks to highlight tumor edge regions as discriminative parts for better classification results, especially for categories with high similarities. The proposed method is evaluated on a BUS image dataset of 1061 images with BI-RADS categories. Experimental results indicate that the proposed method significantly improves over the baseline model by 4.73% in terms of top-1 accuracy.
