Distracting or informative? Examining signage for cyclists using eye-tracking
Authors: Aasvik Ole , Fyhri Aslak
Published: September 2022

There is great political motivation to improve conditions for cyclists to help solving the transport needs of the future. We used eye-tracking to collect data and analysed it using a novel machine learning approach. 40 cyclists in total were tasked with navigating a set route through the Oslo city centre. One group before the new infrastructure was in place and one group after. The analysis focused on developing a method that could be used to investigate how a new signage strategy impacted cyclists in Oslo. Improving signage could create safer traffic conditions for cyclists, while avoiding adding distracting elements. The algorithms developed were able to detect and categorize a variety of important objects. The signage system itself seemed to result in some route change among cyclists, but not all followed the suggested route. Qualitative analyses suggests that those who deviated cycled faster and looked less at signs, than those who chose the suggested route. The paper discusses strengths and weaknesses involved in this approach. While useful, one should be careful to conclude that gaze behaviour reflects the true inner consciousness of cyclists.

Published: September 2022

This current work mainly focuses on the enhancement of the heat transfer and fluid flow characteristics of shell-and-tube heat exchangers by incorporating dimples on the smooth or conventional tubes. With the aid of the ANSYS (Fluent) commercial software package, Computational Fluid Dynamics (CFD) simulations under a steady-state condition were conducted on heat exchanger having a single shell and 12 tubes (with or without dimples), 50% baffle cut, 100mm baffle spacing and turbulent flow. The temperature, velocity, and pressure fields at the shell and tube zone in both cases are analyzed. The computational fluid dynamics results of the heat exchanger with dimpled tubes are compared with conventional (smooth) tubes. However, the results show that a shell and tube heat exchanger with dimpled tubes has a higher overall heat transfer coefficient than that of conventional (smooth) tubes. This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

The genus Eucalyptus occurs in a large range of environmental conditions, mainly arid/semi-arid areas. It includes species with high capacity to survive with extremely low water potential. For that, our review shows an important effect of drought on Eucalyptus spp. plants’ resistance mechanisms and management strategies. In fact, water stress acts directly on growth, productivity, yield, it affects also response to pests and diseases, disturbs wood formation and essential oil yield. However, the general patterns of response to water stress varied among species, genotypes, hybrids and clones. To assume, reducing water loss in eucalyptus species is manifested by reducing leaves area, reducing gas exchange, increasing water uptake thanks to a prolific and deep root systems. A greater accumulation of osmolytes that gives rise to osmotic adjustment including carbohydrates especially cyclitols and quercitol, other amino acids and organic acids, also some proteins which play a vital role in sustaining cellular functions under drought conditions. More than that, water stress increases mainly the levels of pigments, chlorophyll fluorescence parameters, malondialdehyde (MDA), abscisic acid (ABA) and the biosynthesis of triacylglycerols (TAGs) in Eucalyptus species.

Authors: Янич Татьяна Валерьевна , Дерхо Марина Аркадьевна
Published: September 2022

Дана оценка влияния прогестерона на лейкоцитарный состав крови в организме беременных телок и нетелей голштинской породы в зависимости от его триместра. Установлено, что наступление и развитие беременности сопровождается сдвигами в лейкоцитарном составе крови телок. При этом увеличивается как общее количество лейкоцитов и развивается «лейкоцитоз беременности», так и изменяется дифференциальный состав лейкоцитарных клеток. В лейкограмме уменьшается число эозинофилов и лимфоцитов и увеличивается нейтрофилов и моноцитов. При этом колебания числа нейтрофилов и лимфоцитов происходят в пределах границ нормы. При наступлении беременности уровень прогестерона в сыворотке крови телок резко повышается, по сравнению с небеременными в 2,93–4,83 раза. Оценка зависимости лейкоцитарного состава крови беременных телок и нетелей от триместра беременности (I фактор) и концентрации прогестерона (II фактор) показывает, что не только данные факторы обладают статистической значимостью, но и их двухфакторных взаимодействия «Триместр беременности × Лейкоцитарные клетки» и «Прогестерон × Лейкоцитарные клетки», что подтверждается преобладанием Fрасчетное над Fкритическое.

Objective: To analyze the correlation between ultrasound combined examination in obstetrics and gynecology and image effect. Methods: Five patients who were treated in obstetrics and gynecology department were examined by transvaginal ultrasound and transabdominal ultrasound, and the image effects after examination were analyzed and compared. Results: TAS (transabdominal ultrasound) has a wide visual field, but it needs patients' bladder filling. TVS (transvaginal ultrasound) does not need to fill the bladder of the patient, so that the uterus, appendages, etc. can be located naturally, and more detailed information can be obtained, but the image field of view is relatively small. Conclusion: Vaginal ultrasound probe has the advantages of high frequency and clear image, and transabdominal ultrasound examination has the advantages of economy, simplicity, practicality, strong penetrating power, large scanning area, wide field of vision and no restriction of marital status of patients. Transabdominal ultrasound examination and transvaginal ultrasound examination can complement each other, so it is suggested that gynecology and obstetrics should take joint examination during examination. In the process of examining patients, different examination methods can obtain different image effects, which is of great significance for the diagnosis of patients.

Renewable energy from ISWM system plays a significant role in clean energy harvesting. SW containing 50% - 60% of methane (CH4) gas, with 40% - 50% carbon dioxide (CO2). CH4 being a valuable resources for clean energy production has 18 - 22 MJm-3 of energy content. Nigeria depends on finite means of energy sources, and are generally non-renewable in nature. Hence, this poise a greater danger to environmental sustainability. Therefore, this research aimed at providing an effective and sustainable dependability from the use of non-renewable to renewable energy sources, leading a shift from oil resource based energy to biodegradable energy & W-t-E resources, all emanating from MSW. Quantitative and qualitative approaches have been adopted in-line with this research work, to effectively evaluate and to extract 100% of CH4 gas (natural gas) available as LFG from SW to be used in domestic, industrial and power electricity generation plants. Technically this is achievable through passive or active gas management system, for an extensive extraction peak productivity period of 1 - 20 yrs. of available waste stream table 3, figure 4 and 7. Similarly an increased waste generated in 2020 from that of 2015, led to the extraction peak production period of 1 – 30 yrs. of continuous energy harvesting table 4, figure 5 and 7 respectively. Hence, there is the need for various stakeholders to invest in effective ISWM to boosting raw material sources for RRR.

Efficacy of Enriched Medium-chain Fatty Acids in Virgin Coconut Oil in Their Antibacterial Activity against Food Pathogens
Authors: Nguyen Van , Diep Tai
Published: September 2022

Free fatty acids (FFA) have been previously shown to be an effective bactericidal agent. In this study, the FFA mixture was attempted to isolate from virgin coconut oil (VCO) using lipases and was fractionated to obtain the enriched medium-chain fatty acids (MCFA) to compare its antibacterial efficacy against food pathogens. Three types of lipases – namely, lipozyme TL 100L, Candida rugosa lipase (CRL), and porcine pancreas lipase (PPL) – were used to compare their efficacy in VCO hydrolysis, in which CRL was found to be the most efficient lipase for the process of VCO hydrolysis at the water: buffer ratio of 1:5, lipase concentration of 5310 U/g, pH 7, and temperature of 40 °C. The vacuum-distillation process was successfully found to fractionate the initial FFA into three fractions: Fraction I containing MCFA (C8–C12) plus Fraction II (C12–C14) and Fraction III containing LCFA (C14–C20). Among these fractions, Fraction I was observed to be the most effective anti-agent against four out of five food pathogens (negative result against Salmonella typhimurium), followed by Fraction II and initial FFA. Antimicrobial activities of study fractions were found effective on both Gram-positive strains and Gram-negative strains.

Published: September 2022

Proteins from oysters were extracted by the alkaline pH shift method and subsequently subjected to hydrolysis using pepsin. The physico-chemical characteristics of the protein isolate and hydrolysate – such as total soluble protein, protein solubility, water absorption capacity (WAC), oil absorption capacity (OAC), bulk density, hygroscopicity, water activity, and moisture – were determined. The results revealed that hydrolysis of oyster protein isolates (OPIs) significantly increased its functionality. Protein hydrolysates have 86–100% solubility at various pH levels. The WAC (5.65 g/g) and OAC (9.44 g/g) were also significantly higher after hydrolysis. However, the hydrolysates have very low bulk density and high hygroscopicity, which should be considered in the packaging and storage of the product. These findings indicate that oyster protein hydrolysates (OPHs) have the potential for food and nutritional applications as a natural additive or as a protein source in special diets.

In agriculture, Aflatoxins are of major concern as they affect the nutrient quality of crops like Groundnut, Maize, and Coffee which are global economic commodities. Aflatoxin-contaminated products cause substantial financial losses and significant health problems in living beings. Aspergillus produces aflatoxins during environmental stress conditions. The International Agency for Research in Cancer (IARC) conducted studies on aflatoxins and found that Aflatoxin B1 (AFB1), Aflatoxin B2 (AFB2), Aflatoxin G1 (AFG1) and Aflatoxin G2 (AFG2) can cause cancer in both humans and animals and are classified into the Group 1 category of chemical hazards for potentiation mutagens. In India, the Food Corporation of India (FCI) monitors Aflatoxin levels in food and feeds. Aflatoxin contamination reduces the quality of groundnuts, maize, and coffee, affecting their exports. Consumption of aflatoxins contaminated feed induces liver cancer, immune suppressions, shunted growth, and in higher amounts, causes death. The current review provides information based on previous studies and newly adapted guidelines and methods showing the impact of aflatoxins on crops such as groundnut, coffee, and maize. The use of artificial intelligence to detect aflatoxin and mitigation opportunities using technologies such as Aflasafe, Aflaguard, hermetic bags, and Purdue Improved Crop Storage (PICS).

Nervous necrosis virus (NNV) is a deadly infectious disease that affects several fish species. It has been found that the NNV utilizes grouper heat shock cognate protein 70 (GHSC70) to enter the host cell. Thus, blocking the virus entry by targeting the responsible protein can protect the fishes from disease. The main objective of the study was to evaluate the inhibitory potentiality of 70 compounds of Azadirachta indica (Neem plant) which has been reported to show potential antiviral activity against various pathogens, but activity against the NNV has not yet been reported. The binding affinity of 70 compounds was calculated against the GHSC70 with the docking and molecular dynamics (MD) simulation approaches. Both the docking and MD methods predict 4 (PubChem CID: 14492795, 10134, 5280863, and 11119228) inhibitory compounds that bind strongly with the GHSC70 protein with a binding affinity of –9.7, –9.5, –9.1, and –9.0 kcal/mol, respectively. Also, the ADMET (absorption, distribution, metabolism, excretion, and toxicity) properties of the compounds confirmed the drug-likeness properties. As a result of the investigation, it may be inferred that Neem plant compounds may act as significant inhibitors of viral entry into the host cell. More in-vitro testing is needed to establish their effectiveness.
The effect of missing levels of nesting in multilevel analysis
Authors: Park Seho , Chung Yujin
Published: September 2022

Multilevel analysis is an appropriate and powerful tool for analyzing hierarchical structure data widely applied from public health to genomic data. In practice, however, we may lose the information on multiple nesting levels in the multilevel analysis since data may fail to capture all levels of hierarchy, or the top or intermediate levels of hierarchy are ignored in the analysis. In this study, we consider a multilevel linear mixed effect model (LMM) with single imputation that can involve all data hierarchy levels in the presence of missing top or intermediate-level clusters. We evaluate and compare the performance of a multilevel LMM with single imputation with other models ignoring the data hierarchy or missing intermediate-level clusters. To this end, we applied a multilevel LMM with single imputation and other models to hierarchically structured cohort data with some intermediate levels missing and to simulated data with various cluster sizes and missing rates of intermediate-level clusters. A thorough simulation study demonstrated that an LMM with single imputation estimates fixed coefficients and variance components of a multilevel model more accurately than other models ignoring data hierarchy or missing clusters in terms of mean squared error and coverage probability. In particular, when models ignoring data hierarchy or missing clusters were applied, the variance components of random effects were overestimated. We observed similar results from the analysis of hierarchically structured cohort data.
Immorality Failure

Published: September 2022

Is the specter of death the greater motivator of life? And, without that specter, would humans lack motivation to work and achieve? In this work of philosophical short story fiction, Peter wakes up to a warning from his computer that the nanites in his grandmother’s body are failing, and she is slowly dying from kidney failure. He spends the morning working to find the source of the sickness and issues. After some work, he realizes that the nanites are producing a product that is slowly poisoning his grandmother; it’s murder! He goes to his 150-year-old grandmother’s house to tell her, only to find out she knows about the issues, and she is the one who created them. Even though she is the creator of the nanites, and is a celebrity scientist of sorts, she has come to the conclusion that without the fear of death, humans lack motivation to excel.

Is it okay to give credit to an unknown person? Is there value in taking credit for the success of your own hard work? In this work of philosophical short story fiction, the narrator is on a road trip and decides to stop in for breakfast at a small-town diner in Gardenia. Like most breakfast diners, the local community is there. He strikes up a conversation with an older gentleman sitting next to him and learns about Elroy Goddard, the most powerful, wealthiest, and probably the kindest, man in their small town. He owns practically everything, and has helped out practically everyone in town at one point or another. Many of the streets and parks are named after him as well. The waiter says he’s her “uncle,” of a sort, and even helped her get the job. However, after additional questioning it becomes clear nobody has actually ever seen Elroy, and his actions and support of the town are more indirect than they seemed at first. The narrator leaves town wondering if Elroy is real at all.

Introduction. Neuroblastoma in solid organs other than the sympathetic nervous system is extremely rare. The most common site of neuroblastoma is the adrenal medulla. Liver neuroblastomas are usually metastatic lesions, particularly from stage 4S adrenal neuroblastoma. Patient review. We report the first case of primary hepatic high-risk neuroblastoma diagnosed in a child older than 12 months. The patient received multimodal oncology treatment, including chemotherapy, surgery, bone marrow transplantation, radiotherapy, and immunotherapy, as well as deep regional hyperthermia. Despite the timely diagnosis, the tumor was refractory to intensive treatment, and the patient died 2.5 years after the diagnosis. Conclusion. The differential diagnosis of primary malignant liver tumors in pediatric patients should include neuro-blastoma, especially in tumors with atypical clinical presentation. The reports of similar cases in the future may contribute to better tumor biology understanding and facilitate clinical management.
