Nationalism and the Modernisation of Thai Architectural Education at Chulalongkorn University in the 1920s and 1930s
Authors: Fusinpaiboon Chomchon , Coomans Thomas , Povatong Pirasri 
Published: December 2021

This paper examines the modernization of Thai architecture through the establishment of Thailand’s first architecture school, its curriculum, its architecture, and the pivotal role of the first generation of Thai architecture professors, who had been educated in England and France. It demonstrates how the establishment of the Faculty of Architecture, Chulalongkorn University, Bangkok, stemmed from the Siamese government’s growing nationalism that aimed to end foreign domination in both Siam’s construction industry and international diplomacy. The process, however, involved the adoption of a western curriculum — which was considered modern — and adapting it to be more Thai for nationalist purposes. This also required support by employing a foreign professor in architecture: Lucien Coppé, a Belgian architect who was responsible for both upgrading the school’s curriculum and the design of its first permanent building in 1938. Furthermore, some aspects of the western curriculum were not intended to be adapted but were hybridized due to the constraints of the modernizing nation. The establishment and construction of the Faculty of Architecture, Chulalongkorn University, are examples of how art, science, and education were intertwined in both national and global politics in the 1930s.

Cross-linked organiс-inorganic sulfo-containing membranes of various compositions based on acrylic monomers (acrylonitrile, acrylic acid, 3-sulfopropylacrylate potassium salt, ethylene glycol diacrylate) and sol-gel systems of tetraethoxysilane have been developed. Synthesis of the polymer matrix was carried out by UV-initiated polymerization of the monomer mixture and the inorganic component was formed in situ while conducting the sol-gel process of the precursor. FTIR, SEM, EDS, DMA, impedance spectroscopy were used to characterize the synthesized materials. The influence of inorganic component content on the properties of the membranes was investigated. DMA results show that an increase in silica content leads to a decrease in packing density and an increase in structural heterogeneity in sulfo-containing polyacrylate/silica membranes. The highest values of proton conductivity 1.12 ꞏ 10−2 Sm/cm at 60 °C were found in membranes containing 3 wt.%. of the added sol-gel system. Further increase of silica content does not increase the proton conductivity of the membranes. The proton transfer activation energies in the membranes were calculated from the temperature dependence of proton conductivity. The obtained cross-linked sulfo-containing organic-inorganic materials can be used for the development of proton-conducting membranes for fuel cells.
Urinary Tract Infection Investigation and Treatment in Older Adults Presenting to the Emergency Department with Confusion: a Health Record Review of Local Practice Patterns
Authors: Pinnell Rhiannan , Ramsay Tim , Wang Han , Joo Pil 
Published: December 2021

Background
The rate of urinary tract infection (UTI) investigation and treatment in confused older emergency department (ED) patients has not been described in the literature. We aim to describe the pattern of practice in an academic tertiary care ED for this common presentation.
Methods
A health record review was conducted on 499 adults aged ≥65 presenting to academic EDs with confusion. Exclusion criteria: Glasgow Coma Scale < 13, current treatment for UTI, indwelling catheters, nephrostomy tubes, transfer from another hospital. Outcomes were the prevalence of UTI investigation, diagnosis and antibiotic treatment.
Results
64.9% received urine tests, 11.4% were diagnosed with UTI, and 35.2% were prescribed antibiotics. In the subgroup with no urinary symptoms, fever, or other obvious indication for antibiotics, these numbers were 58.2%, 7.6%, and 18.1%, respectively. Patients who had urine tests or received antibiotics were older than those who did not (p values < .01). Patients receiving antibiotics had higher admission rates and 30-day and six-month mortality (OR of 2.9 [2.0–4.3], 4.0 [1.6–11], and 2.8 [1.4–5.8], respectively).
Conclusion
Older patients presenting to ED with confusion were frequently investigated and treated for UTI, even in the absence of urinary symptoms. Antibiotic treatment was associated with higher hospitalization and mortality.
A Schwarz lemma for hyperbolic harmonic mappings in the unit ball
Authors: Chen Jiaolong , Kalaj David 
Published: December 2021

Assume that $p\in [1,\infty ]$ and $u=P_{h}[\phi ]$, where $\phi \in L^{p}(\mathbb{S}^{n-1},\mathbb{R}^n)$ and $u(0) = 0$. Then we obtain the sharp inequality $\lvert u(x) \rvert \le G_p(\lvert x \rvert )\lVert \phi \rVert_{L^{p}}$ for some smooth function $G_p$ vanishing at $0$. Moreover, we obtain an explicit form of the sharp constant $C_p$ in the inequality $\lVert Du(0)\rVert \le C_p\lVert \phi \rVert \le C_p\lVert \phi \rVert_{L^{p}}$. These two results generalize and extend some known results from the harmonic mapping theory (D. Kalaj, Complex Anal. Oper. Theory 12 (2018), 545–554, Theorem 2.1) and the hyperbolic harmonic theory (B. Burgeth, Manuscripta Math. 77 (1992), 283–291, Theorem 1).

Published: December 2021

Aims: The aim of this study was to assess the risk of exposure to pyrethrinoids and oragnophosphorus pesticides found in Côte d’Ivoire kola nuts.
Study Design: Kola nuts samples were collected from farmers, collectors and urban stores in 3 regions (western, southwestern and eastern) and 2 big storage centers of Côte d’Ivoire.
Place and Duration of Study: Health Department of Hydrology Health and Toxicology, Training and Research Unit of Pharmaceutical and Biological Sciences, Abidjan, Côte d’Ivoire, running 2017-2020.
Methodology: Pyrethrinoids and organophosphorus residues were qualitatively and quantitatively determined using Liquid Chromatography-Tandem mass spectrometry Agilent 1290 Infinity II LC (LC-MS/MS) and their potential health risks assessed in kola nuts samples from selected regions of Côte d’Ivoire. Health risk estimates were analyzed using Estimated Average Daily Intake (EADI) and Hazard Index (HI) with risk categorized for non-carcinogenic health effects.
Results: A total of 12 pyrethrinoids and 3 organophosphorus were identified and their residues were detected in all the kola nuts samples analyzed. The results showed that the mean concentration of organphosphorus in all kola nuts was 5±1 µg/kg FW. This level is the same observed for acrinathrin, delatmethrin, fenpropathrin, fenvelerate, flucythrinate, tau-fluvalinate, cyfluthrin et tefluthrin. As for the other pyrethrinoids, the values obtained are 17.2±6.2 µg/kg FW, 25±14.6 µg/kg FW, 30±11.3 µg/kg FW and 39.4±21.2 µg/kg FW, respectively for bifenthrin, cypermethrin, permethrin and cyhalothrin. The average contents determined for each active molecule are all lower than the MRLs fixed for these residues in the kola nuts. As a result, all the Estimate Average Daily Intake (EADIs) determined in adult Ivorians are lower than the corresponding Toxicological References Values (TRVs). Thus, the Hazard Quotient (HQ) calculated for each substance is less than 1.
Conclusion: The risk of adverse effects from consuming kola nuts contaminated with residues of pyrethrinoids or organophosphorus is very unlikely.

Authors: Alsharafi Mohammed , Zeren Yusuf , Alameri Abdu 
Published: December 2021

In chemical graph theory, a topological descriptor is a numerical quantity that is based on the chemical structure of underlying chemical compound. Topological indices play an important role in chemical graph theory especially in the quantitative structure-property relationship (QSPR) and quantitative structure-activity relationship (QSAR). In this paper, we present explicit formulae for some basic mathematical operations for the second hyper-Zagreb index of complement graph containing the join G1 + G2, tensor product G1 \(\otimes\) G2, Cartesian product G1 x G2, composition G1 \(\circ\) G2, strong product G1 * G2, disjunction G1 V G2 and symmetric difference G1 \(\oplus\) G2. Moreover, we studied the second hyper-Zagreb index for some certain important physicochemical structures such as molecular complement graphs of V-Phenylenic Nanotube V PHX[q, p], V-Phenylenic Nanotorus V PHY [m, n] and Titania Nanotubes TiO2.

Authors: Hossen Md. Imran , Ahmed Toufiq , Arefin Riyadh 
Published: December 2021

Aims: Pruning is the cutting of branches of a tea bush at predetermined height and at a specified interval in order to reinvigorate and bring tea bushes within reach of the pluckers, which directly related to the productivity and quality of tea. In Bangladesh, Three and four year pruning cycles were the conventional recommendations for the tea plantation. In this experiment, along with BTRI recommended four types of pruning operations (LP, DSK, MSK and LSK), two more types of pruning operations such as: UP (Unprune) and LoS (Level of Skiff) were considered as treatments. This experiment was conducted with two main objectives: to evaluate the yield and yield related parameters of tea due to different types of pruning operations as well as to find out the effect of pruning operations on organoleptic quality of black tea.
Study Design, Place and Duration of Study: This experiment was conducted ‘D2 Thall’ area at the main research farm of Bangladesh Tea Research Institute (BTRI) from December 2017 to November 2019. The experimental design was Randomized Completely Block Design (RCBD) with six treatments and three replications.
Methodology:
The treatments are denoted as T1 (UP: Unpruned) control, T2 (LP: Light Pruning), T3 (DSK: Deep Skiffing), T4 (MSK: Medium Skiffing), T5 (LSK: Light Skiffing) and T6 (LoS: Level of Skiffing) respectively. Data were collected under the following parameters:

Number of plucking point or pluckable shoot/bush in each plucking
Fresh weight (g) of 100 shoots (three leaves and a bud)
Oven Dry weight (g) of 100 shoots (three leaves and a bud) to calculate Dry Matter Content
Green leaf weight (kg) to calculate Yield of each treatment
Number of plucking round to calculate Yield gap of each treatment
Black Tea Quality of each treatment by Organoleptic Tasting Method.

Results: It was found that, number of plucking points/pluckable shoot and yield were found significantly high in T6 (Level of Skiffing), T5 (Light Skiffing) and T1 (Unpruned) than the other treatments. But in terms of tea quality, lowest quality tea was found in T1 (Unpruned), T6 (Level of Skiffing) and T5 (Light Skiffing) treatment. So, it can be concluded that, ‘Skiff Pruning’ or ‘Unprune’ technique had positive effect on yield but the quality of these technique were poor in comparison with other treatments. T2 (Light Pruning) treatment gave more tender and fresh shoot than the other treatment. For this reason, dry matter was low in T2 (Light Pruning) treatment but tea quality was much better than the other pruning technique.
Conclusion: Pruning has positive or negative effect on yield and quality of tea. ‘Skiff Pruning’ or
‘Unprune’ has positive effect on yield but the quality of is poor than the other treatments. Best Quality tea can be produced from Light Pruning tea section because of having more tender and fresh shoot than other treatments.

Published: December 2021

AbstractMetastable orthorhombic niobium pentoxide (T‐Nb2O5) is a promising anode to fulfill the requirements for high‐rate Li‐ion batteries (LIBs). Stoichiometric T‐Nb2O5 is plagued by low electric conductivity and particle pulverization after repeated charge/discharge processes. In this work, oxygen vacancies are implanted into T‐Nb2O5 particles via acid immersion of Nb2O5·nH2O with the formation of Lewis acid sites. The multiple characterizations and simulations reveal the lengthening of NbO bonds, and the transformation from NbO7 pentagonal bipyramids and NbO6 tetragonal bipyramids in T‐Nb2O5−x. The enrichment of oxygen vacancies endows T‐Nb2O5−x with higher electric conductivity, better electrochemical kinetics, larger pseudocapacitive contribution. O‐doped graphitic C3N4 is creatively proposed as a trace oxygen pump to repair excessive oxygen vacancies, and it also serves as a sacrifice template for Nb2O5−x growth to construct a porous and monolithic electrode network. Defect‐modulated Nb2O5−x displays extraordinary cycling stability (164 mAh g−1 at 5 C after 1100 cycles), high capacity retention (104 mAh g−1) at an ultrahigh rate (25 C), and large areal capacity (0.74 mAh cm−2) under high mass loading (4 mg cm−2). The practical prospect is proved by Nb2O5−x/LiNi0.8Co0.1Mn0.1O2 full cells with high average platform (2.12 V) and high specific capacity (229 mAh g−1). The oxygen‐defect modulation strategy on oxide anodes provides an alternative solution to fast‐charging and durable LIBs.

AbstractSpatially random lithium nucleation and sluggish lithium diffusion across the electrode/electrolyte interface lead to uncontrollable lithium deposition and the growth of lithium dendrite on metallic lithium surface, causing severe safety problems. Herein, a functional rapid‐ion‐diffusion alloy layer on the metallic lithium surface (RIDAL‐Li) is designed through a simple chemical reduction reaction. Such a layer efficiently reduces energy barriers for lithium transport and thus significantly homogenizes the lithium atom flux for lateral deposition, which are confirmed by electrochemical tests, theoretical simulations, and spectroscopic analysis. Furthermore, the as‐prepared RIDAL layer also displays a much higher corrosion resistance to moisture and oxygen. As a result, in ether‐based and carbonate‐based electrolytes, the pretreated RIDAL‐Li anode can achieve a long stripping/plating lifespan of 900 h and a high Coulombic efficiency of 99% without dendrite growth. Even after being exposed to the ambient environment with relative humidity of 51% for 60 min, the RIDAL‐Li can survive for stripping/plating 400 h and exhibit a low overpotential of 18 mV, displaying the superiority for ambient atmosphere battery assembly. Matched with LiFePO4 or sulfur cathode, the full cells exhibit remarkably improved stability and capacity retention, showing its suitability for applications in lithium metal batteries.

AbstractThe visionary idea that RNA adopts nonbiological roles in today's nanomaterial world has been nothing short of phenomenal. These RNA molecules have ample chemical functionality and self‐assemble to form distinct nanostructures in response to external stimuli. They may be combined with inorganic materials to produce nanomachines that carry cargo to a target site in a controlled manner and respond dynamically to environmental changes. Comparable to biological cells, programmed RNA nanomachines have the potential to replicate bone healing in vitro. Here, an RNA–biomineral nanomachine is developed, which accomplishes intrafibrillar and extrafibrillar mineralization of collagen scaffolds to mimic bone formation in vitro. Molecular dynamics simulation indicates that noncovalent hydrogen bonding provides the energy source that initiates self‐assembly of these nanomachines. Incorporation of the RNA–biomineral nanomachines into collagen scaffolds in vivo creates an osteoinductive microenvironment within a bone defect that is conducive to rapid biomineralization and osteogenesis. Addition of RNA‐degrading enzymes into RNA–biomineral nanomachines further creates a stop signal that inhibits unwarranted bone formation in tissues. The potential of RNA in building functional nanostructures has been underestimated in the past. The concept of RNA–biomineral nanomachines participating in physiological processes may transform the nanoscopic world of life science.
