Norbornyl benzocyclobutene ladder polymers: Conformation and microporosity

Shape-persistent contorted ladder polymers are an intriguing and unusual class of polymers. Using catalytic arene-norbornene annulation (CANAL) polymerization and with norbornadiene and dibromoarenes as monomers, we synthesized a series of ladder polymers with fused norbornyl benzocyclobutene backbones and varied conformations. A diaryl spiro-orthocarbonate monomer was used to reorient the ladder backbone perpendicularly to induce three-dimensional kinks, and a p-dibromo-xylene comonomer was used to statistically vary the distance between the spirocyclic kinks in the ladder backbone. Norbornyl benzocyclobutene ladder polymers with no spirocyclic backbone twists possess much more compact conformations than ladder polymers with frequent spirocyclic backbone twists in solution. While spirocyclic twists in the polymer backbone had minor effects on the surface area and microporosity, incorporation of rotatable single bonds in the repeat unit significantly decreased both the surface area and pore volume. © 2017 Wiley Periodicals, Inc.

In this study, we focused on the researches about nutrient leaching loss using a lysimeter in the world. We aimed at reviewing key studies and planning further research directions using the weighable lysimeters in Korea. In response to climate changes, environmental issues, and policies for sustainable agriculture, the experiments using a lysimeter were performed to better understand the nutrient leaching loss in the soils. The research topics were about crop rotation, soil amendment, nitrification inhibitors and what were better practices for reducing nutrient leaching including nitrogen. In addition, some researches focused on developing optimal models to predict the nutrient leaching loss in the soils that have a variety of environments. Current study suggests that the studies of the nutrient leaching loss combined with water dynamics using weighable lysimeters in Korea are to be fostered so that they may provide scientific guidelines on the issues and policies such as sustainable agriculture, climate change, fertilizer recommendation, and nutrient balance.
Qualitative Identification of Roseburia hominis in Faeces Samples Obtained from Patients with Irritable Bowel Syndrome and Healthy Individuals

Various products coded by genes recognized in microbiota are involved in many biochemical pathways in thehuman body. Bacteria composition in the gastrointestinal tract may be an important aspect of selected diseases’ pathogenesis, including irritable bowel syndrome (IBS). Traditional research methods based on classical microbiology, using selective media for bacterial growth, have proven to be ineffective. The use of genetic methods allows the identification of unidentified microbiota, including anaerobes. Roseburia hominis is a flagellated gut anaerobic commensal bacterium, producing short-fatty acids. The knowledge about the microbial components of the intestinal ecosystem is still very limited, including Roseburia hominis. This study aimed to identify Roseburia hominis in the faeces samples obtained from IBS patients and healthy individuals, using PCR techniques. The differences between studied groups were observed, and it was concluded that R. hominis may play a role in IBS etiology.
Performance improvement of countercurrent-flow membrane gas absorption in a hollow fiber gas-liquid membrane contactor

The theoretical membrane gas absorption module treatments in a hollow fiber gas-liquid membrane contactor using Happel’s free surface model were obtained under countercurrent-flow operations. The analytical solutions were obtained using the separated variable method with an orthogonal expansion technique extended in power series. The CO 2 concentration in the liquid absorbent, total absorption rate and absorption efficiency were calculated theoretically and experimentally with the liquid absorbent flow rate, gas feed flow rate and initial CO 2 concentration in the gas feed as parameters. The improvements in device performance under countercurrent-flow operations to increase the absorption efficiency in a carbon dioxide and nitrogen gas feed mixture using a pure water liquid absorbent were achieved and compared with those in the concurrent-flow operation. Both good qualitative and quantitative agreements were achieved between the experimental results and theoretical predictions for countercurrent flow in a hollow fiber gas-liquid membrane contactor with accuracy of 6.62×10 -2 ≤ E ≤8.98×10 -2 . the total ω and efficiency for both concurrent- and countercurrent-flow with CO concentration and mass-transfer Graetz number parameters, The theoretical the total rate ω
Sedation During Oral Treatment in Special Care Patients: An Integrative Review

Dental care in patients with special needs has always been challenging. According to the Dental Accreditation Commission (CODA), patients with special needs are defined as any individual who has a medical, psychological, physical or social condition, who needs individualized dental treatment [1]. Among these, neurological motor disorders such as Down Syndrome, Cerebral Palsy or even patients diagnosed with Autistic Spectrum Disorder (ASD) are often not able to have emotional control or complete intellectual development, and their ability to understand and cooperate may be affected by undergoing dental treatment [2,3]. Most of the time conditioning is the first method of choice for care, but it is not always enough. In these cases we use conscious sedation, a technique that can be performed with one or a combination of more medications that establish a state of depression of the central nervous system, effectively and safely whether performed by oral, nasal, intramuscular, intravenous (IV), subcutaneous or inhaled [4]. Thus, it allows the necessary dental treatment to be performed in a less traumatic way for the patient and more comfortable to the professional [5].

The Effect of Flipping a Foreign Language Writing Course on Writing Performance and Writing Motivation

To explore the effectiveness of flipped instruction in influencing second language learning outcomes, the current research investigated the contribution of flipped classrooms of an English-as-a-Foreign-Language (EFL) writing course to Iranian learners’ writing development and writing motivation. In so doing, two intact classes were chosen as the participants (N=43) of this research and they were randomly assigned to a Control Group (N = 18) and an Experimental Group (N = 25). During one semester, the Control Group underwent the traditional writing instruction, while the Experimental Group received a flipped writing instruction. Second Language Writing Motivation Scale (SLWMS) and two timed writing tasks were given to gather the required data. The results demonstrated that the flipped method of teaching was substantially effective in improving the L2 writing performance of the experimental group (F= 22.20, p = 0.000, partial eta squared = 0.35). Also, the results indicated that the flipped instruction had a statistically significant effect on learners’ writing motivation (F= 51.67, p = 0.000, partial eta squared = 0.56). The findings have remarkable implications for L2 writing methodology.
Ginsenoside Rg1 alleviates Aβ deposition and neuronal damage by inhibiting NLRP1 in�ammasome activation in APP/PS1 mice

Background: Oxidative stress and neuroin�ammation play important roles in the whole pathogenesis of Alzheimer's disease (AD). NADPH oxidase 2 (NOX2) is an important enzyme that is responsible for ROS generation in many neurodegenerative diseases. The nucleotide-binding oligomerization domain (NOD)-like receptor protein 1 (NLRP1) in�ammasome is responsible for the formation of pro-in�ammatory molecules in neurons. However, it is still unclear whether inhibition of NOX2 and NLRP1 in�ammasome decreases amyloid-beta (Aβ) generation and deposition in APP/PS1 mice. Ginsenoside Rg1 (Rg1) is an active component in ginseng, and maybe a potential agent for neurodegenerative diseases. In this study, we investigated the effects and mechanisms of Rg1 treatment on cognitive performance, neuronal damage, Aβ deposition and NOX2-NLRP1 in�ammasome activation in APP/PS1 mice. Methods: WT and APP/PS1 mice were used in the experiment from 6 months (M) old to 9M old, and 6M APP/PS1 mice were used as pre-treatment controls. The open �eld test (OFT) and Morris water maze (MWM) were used to detect behavioral change and cognitive function. The H&E and Nissl staining were used to assess neuronal damage. We further examined PSD95 expression, Aβ generation and deposition, Tau and p-Tau expression, NOX2-mediated ROS generation and NLRP1 in�ammasome activation by using immuno�uorescence, western blot analysis, and real time q-PCR. Results: Rg1 treatment for 12 weeks alleviated learning and memory impairments and neuronal damage, decreased p-Tau level, APP expression and Aβ deposition in APP/PS1 mice. Meanwhile, Rg1 treatment signi�cantly decreased the levels of ROS and IL-1β, and reduced the expressions of NOX2 and NLRP1 in�ammasome in the brain cortex and hippocampus in APP/PS1 mice. Furthermore, apocynin (a NOX inhibitor) and NLRP1-siRNA treatment also alleviated cognitive into Aβ. In the present study, the results showed that Rg1 treatment had no signi�cant effect on NCSTN expression, but could signi�cantly decrease the expression levels of APP, BACE and CTF-β, which were signi�cantly increased in APP/PS1-9M mice. Meanwhile, we also detected the expression of Aβ 1-42 , a pernicious peptide, and the levels of amyloid plaque in the cortex and hippocampus. The results showed that Rg1 treatment signi�cantly decreased the expression of Aβ 1-42 and the levels of amyloid plaque in APP/PS1 mice. Additionally, Rg1 treatment signi�cantly decreased the levels of p-Tau and senescence-associated β-Gal that were also signi�cantly increased in the APP/PS-9M mice. These results suggest that Rg1 may not only decrease APP expression but also inhibit the β-secretase pathway in APP processing to hinder pernicious Aβ formation.
Factor Investing, Learning from Prices, and Endogenous Uncertainty in Asset Markets

We study learning and uncertainty under the factor investing paradigm using an endogenous information model with correlated assets. As investors shift attention from firms towards systematic risk factors, stock prices become less informative, increasing systematic uncertainty and incentivizing learning about the systematic risk. This learning complementarity leads to multiple regimes in systematic uncertainty and attention allocation. We specify and estimate a model-based, forward-looking measure of attention to systematic versus firm-level information. Consistent with the model, the measure follows a regime-switching process. The high-level regime is linked to lower stock price sensitivity to firm-specific information and a higher systematic risk concentration.
Bacteriological Profile of Diabetic Foot Infection and Its Effect on Limb Salvation

Background: Foot ulceration has been reported as the leading cause of hospital admission and amputation in individuals with diabetes. Diabetes-related foot ulcers require multidisciplinary management and care, including debridement, offloading, dressings, management of infection, modified footwear and management of extrinsic factors. Objective: To identify the bacterial pathogens responsible for diabetic foot infections and its effect on limb salvation. Methods: This prospective observational and cross sectional study was conducted among 100 diabetic foot ulceration patients in Mainamati Medical College Hospital, Cumilla between the period of January, 2017 to December, 2018. The patients with diabetic foot ulcer Wagner Grade (2-5) irrespective of age and sex were included in the study. They were thoroughly examined and swab from ulcer base was collected by sterile swab stick and container supplied by the microbiology department. A pre-structured, peer reviewed, interview and observation based data collection sheet was prepared that was used as a research tool. Data regarding clinical, hematological and bacteriological profile were recorded by data collection sheet. Data were entered, managed and analyzed. Results: Diabetic foot was very common in the elderly age group (51-60yrs) 38% and male predominant (78%). Staphylococcus aureus (35%) is the commonest pathogens affecting as the gram positive cocci whereas pseudomonas (23%) is the commonest among the gram negative bacilli. Chloramphenicol, Amikacin, Vancomycin were the most sensitive drugs against gram positive cocci whereas, Cefuroxin, Co-trimoxazole and Gentamycin found the most sensitive drugs against gram negative bacilli. Incision, drainage and dressing (31%) found the commonest treatment modality. The other treatment modalities were debridement, dressing and reconstruction conservative dressing, above and below knee amputation, toe disarticulation etc. Conclusion: Diabetic foot is usually affected by Staphylococcus aureus and streptococcus among the gram positive cocci and pseudomonas whereas Chlamydia and E. coli among the gram negative bacilli. For the limb salvage incision & drainage as well as debridement, excision and reconstruction are the mostly chosen procedure. Journal of Surgical Sciences (2020) Vol. 24 (1) : 21-25
New polymeric proton conductors for water-free and high temperature fuel cells

Introduction Due to the considerable interest in PEM fuel cells for transportation purposes there has arisen a need to examine the feasibility of proton conducting membranes that do not depend on the presence of water for their performance. The most attractive option would involve a true solid-state material that contains no free solvent, can tolerate the presence of water, is conductive at low temperatures as well as high temperatures and can be tailored to provide desired gas permeabilities for both the separator and the membrane-electrode assembly. To accomplish this a somewhat complicated polyelectrolyte structure is necessary but an example of a candidate structure is shown in Figure 1 that illustrates some of the principles involved in proton transport in a solid polymer electrolyte.
Observing Growth of Nanostructured ZnO in Liquid

Hydrothermal synthesis is commonly used to produce a large area of ZnO nanowires because of its simple and inexpensive process. However, the mechanism of hydrothermal synthesis remains unknown. In this work, zinc acetate and HMTA dissolved in deionized water as a precursor solution were sealed in a liquid cell for observation by in situ transmission electron microscopy. The growth of ZnO nanowires was classified into two steps. The first step was the nucleation and growth of ZnO nanoparticles. The ZnO nanoparticles grew as a result of either isotropic monomer attachment on the {2110} and {0110} surfaces or coalescence of nanoparticles in the same crystal arrangement. The second step was the anisotropic growth of ZnO nanoparticles into nanowires on the (0001) surface. Because the (0001) surface is Zn-terminated with positive charges that can attract the negatively charged monomers, i.e., [Zn(OH)4]2–,the monomers tended to deposit on the (0001) surface, resulting in ZnO nanowires growing along the [0001].

Blockchain-Enabled Traceability in Food Supply Chain Networks

Innovative retailers in food supply chains have been exploring blockchain as part of an ongoing effort to reduce contamination risks and food waste. We develop a three-tier supply chain model with multiple upstream (tier-2) suppliers to investigate: how blockchain adoption affects incentives of supply chain members, and whether and how its anticipated benefits can be realized. We find that blockchain-enabled full traceability brings direct revenue benefit to every supply chain member by saving uncontaminated food from disposal (pure traceability effect), but also leaves each tier of the supply chain vulnerable to its immediate downstream buyer’s exploitation through strategically lowering the purchasing price (strategic pricing effect). The interplay of the two effects may result in some of the supply chain members (even the retailer) being worse off with blockchain adoption, and the system being exposed to higher contamination risk; the latter is due to the weakened upstream supplier’s incentive to exert contamination risk-reduction effort. Moreover, the supply chain network structure also influences the benefit distribution of blockchain adoption: The retailer always benefits from blockchain adoption in network structures where the tier-1 supplier’s strategic pricing power is eliminated or weakened; all supply chain members benefit from blockchain adoption in a network with a large number of tier-2 suppliers. Finally, we show that alternative risk-mitigation schemes such as tier-2 coordination can diminish the value of blockchain adoption, and partial traceability enabled by tier-1 product inspection can be more beneficial to the retailer than blockchain adoption.
