CaLaAlO4/LaAlO3: 0.5%Tm3+, xYb3+ upconversion phosphors were prepared via the combustion method. The Tm3+ dopant concentration was constant (Tm=0.5mol%), while the concentration of Yb3+ co-dopant was varied (Yb = 1 – 10 mol%). The X-ray diffraction studies indicated a mixture of phases (tetragonal and hexagonal of CaLaAlO4 and LaAlO3 respectively). The optical absorption spectra of the upconversion phosphors have two absorption bands centered at 253 nm, and another band at 440 nm. The band at 253 nm is ascribed to the charge transfer band (CTB) between the ligand (O2-) and Yb3+ ions, while the broad band located at 440 nm was related to defect states in the lattice. The energy bandgap and refractive index of the optimized phosphor were 4.73 eV and 1.76 respectively. The upconversion emission peaks centered at 478 nm (1G4 → 3H6), 654 nm (1G4 → 3F4), and 801 nm (3H4 → 3H6) are associated to the electronic transitions of Tm3+ ions. As the Yb concentration increases, the colour emission is tuned from bluish white to blue light. The CCT and CIE coordinate of (0.2419, 0.2463) showed that the phosphor doped with 10 mol% of Yb3+ produces a bluish-white and its colour purity was 80%. Thus, the strong bluish-white light emission produced by the CaLaAlO4/LaAlO3: 0.5%Tm3+, xYb3+ phosphors could be used for solid-state lighting (SSL) or in multicolour displays.

Ovarian follicular waves in ovulation induction in assisted reproduction techniques
Authors: Wanyoike Gichuhi  
Published: February 2024

Background: A greater understanding of the menstrual cycle and multiple waves of antral ovarian follicular development has challenged traditional concepts of female reproductive physiology and the foundations of assisted reproductive technologies (ART). Approximately two-thirds of women develop two follicle waves throughout an interovulatory interval, and the remainder exhibit three waves of follicle development. Major and minor waves of follicle development have been observed. Major waves are those in which a dominant follicle develops; dominant follicles either regress or ovulate. In minor waves, the physiological selection of a dominant follicle is not manifested. Knowledge of the waves of antral follicular development has led to the global adoption of novel ovarian stimulation strategies in which stimulation can be initiated at various times throughout the cycle. Random-start and luteal-phase ovarian stimulation regimens have important clinical applications in women requiring urgent oocyte or embryo cryopreservation for fertility preservation before chemotherapy.
Objective: To evaluate the role of multiple waves of the antral ovarian follicular in the menstrual cycle in ovulation induction in ART.
Methods: A literature search using the keywords “multiple waves of antral ovarian follicular development, In Vitro Fertilization, Ovarian stimulation ” was performed in the PubMed database.
Outcome: Random start and luteal phase of ovulation induction in ART offer the same results in fertilization and pregnancy rates as conventional early follicular phase start.
Conclusion: The primary benefits of the random-start protocol include a patient-oriented approach to care, timely and efficient treatment, and a lower dropout rate. Women with poor ovarian reserve and those diagnosed with cancer will have a greater chance of successful assisted reproduction with the use of these strategies.

Published: February 2024

Background
Proton-pump inhibitors (PPIs) are prescribed to treat gastric acid-related diseases, while they may also have potential risks to population health. Recent studies suggested that a potential mechanism explaining the association between PPIs and cardiovascular diseases (CVD) includes the inhibition of the nitrate-nitrite-nitric oxide (NO) pathway. However, previous observational studies showed controversial results of the association. In addition, the inhibition of the NO pathway due to PPIs use may lead to peripheral vascular diseases (PVD); however, none of the studies explore the PPI-PVD association. Therefore, this study aimed to evaluate the association of PPIs with circulatory diseases (CVD, ischemic strokes or IS, and PVD).

Methods
We conducted a retrospective hospital-based cohort study from Oct 2010 to Sep 2017 in Songkhla province, Thailand. PPIs and histamine 2-receptor antagonists (H2RAs) prescriptions were collected from electronic pharmacy records, while diagnostic outcomes were retrieved from electronic medical records at Songklanagarind hospital. Patients were followed up with an on-treatment approach. Cox proportional hazard models were applied to measure the association comparing PPIs vs H2RAs after 1:1 propensity-score-matching. Sub-group analysis, multi-bias E-values, and array-based sensitivity analysis for some covariates were used to assess the robustness of associations.

Results
A total of 3,928 new PPIs and 3,928 H2RAs users were included in the 1:1 propensity score-matched cohort. As compared with H2RAs, the association of PPIs with CVD, IS, and PVD, the hazard ratios were 1.76 95% CI = [1.40–2.20] for CVD, 3.53 95% CI = [2.21–5.64] for ischemic strokes, and 17.07 95% CI = [13.82–76.25] for PVD. The association between PPIs and each outcome was significant with medication persistent ratio of over 50%. In addition, the association between PPIs and circulatory diseases was robust to unmeasured confounders (i.e., smoking and alcohol).

Conclusion
PPIs were associated with circulatory diseases, particularly ischemic strokes in this hospital-based cohort study, whereas, the strength of associations was robust to unmeasured confounders.

Personnel recruitment processes in various government agencies, ministries, boards, and parastatals encounter challenges in effectively selecting candidates who meet specified requirements for job placement on time. Moreover, human resource (HR) managers face the additional burden of appeasing top government officials while also mitigating issues of nepotism and bias during recruitment. The success or failure of any organization heavily relies on the recruitment and retention of its workforce. Consequently, the decision to select suitable candidates for job positions is of utmost importance to management in every organization. This work develops a structured intelligent system that selects the best machine learning (ML) classification model for predicting applicants’ employability based on their attributes using the industry job selection criteria. A dataset of 16240 applicants’ records collected from Akwa State Universal Basic Education Board (AKSUBEB) was used to train and test the performance of the ML models. Naïve Bayes (NB), Logistic Regression (LR), Support Vector Machines (SVM), Random Forest (RF), and Decision Tree (DT) classifiers were deployed where results indicate that DT emerged the most effective classifier with a 98% prediction accuracy followed by RF with accuracy of 97.59% while LR recorded the least accuracy of 79.43%. This outcome indicates that tree-based ML structures can significantly help HR personnel to efficiently select suitable candidates for given job positions with reduced overhead in the recruitment process.

Published: March 2005

AbstractPoly(ethylene terephthalate) (PET) waste flakes (blow‐molded‐grade industrial waste) were degraded with aqueous methylamine and ammonia at room temperature in the presence and absence of quaternary ammonium salt as a catalyst for various times. The catalyst reduced the time required for the degradation of the PET waste. The degraded products were analyzed with IR, nuclear magnetic resonance, mass spectrometry, and differential thermal analysis and were characterized as N,N′‐dimethylterephthalamide and terephthalamide in the case of methylamine and ammonia, respectively. © 2005 Wiley Periodicals, Inc.

Published: March 2005

AbstractUltrahigh molecular weight polyethylene (UHMWPE) has high yield strength and modulus, but is nonpolar and chemically inert. For it to be used as an effective reinforcing agent for composites, methods to make the UHMWPE wettable or capable of reaction with the matrix are critical. In the current work, Spectra 900™ (UHMWPE) fibers were surface modified by swelling in p‐xylene with: (1) methylmethacrylate (MMA) monomer; (2) PMMA; (3) camphorquinone (CQ); (4) 3‐methacryloxypropyltrichlorosilane (Cl‐MPS); (5) trimethoxysilyl modified polyethylene, N‐(triethoxysilylpropyl)‐dansylamide (fluorescent silane), or octadecyltrimethoxy silane (OMS), followed by hydrolysis and reaction with Cl‐MPS; and (6) by coating with SiO2 films followed by reaction with MPS. These modifiers were used to improve wettability and provide sites for chemical interactions with the resin matrix. Beads of resin [60/40 BisGMA‐TEGMA (bis‐phenol A bis‐(2‐hydroxypropyl) methacrylate and tri(ethylene glycol) dimethacrylate)] were light‐cured around the treated fibers and the improvement in adhesion was tested by microbond shear strength (τ) tests. The improvements were comparable to those reported by acid etching and plasma treatments. The OMS, fluorescent silane, and SiO2/Cl‐MPS treatments yielded the best results, that is fourfold increases in τ compared with untreated fibers. © 2005 Wiley Periodicals, Inc.

A novel positive‐type photosensitive polyimide having excellent transparency based on soluble block copolyimide with hydroxyl group and diazonaphthoquintone
Authors: Jin XingZhou , Ishii Hiroyuki 
Published: March 2005

AbstractA novel positive‐type photosensitive polyimide having excellent transparency based on soluble block copolyimide (Bco‐PI) with hydroxyl group and diazonaphthoquinone (DNQ) as a photoreactive compound was developed. The base Bco‐PI A was prepared by a direct one‐pot polycondensation of cyclohexanetetracarboxylic dianhydride (H‐PMDA), 2,2‐bis(3‐amino‐4‐hydroxyphenylhexafluoropropane) (Bis‐AP‐AF), and bis(4‐(3‐aminophenoxy)phenyl)sulfone (m‐BAPS) in the presence of a γ‐valerolactone and pyridine catalyst system by using dipolar aprotic solvent such as N‐methyl‐2‐pyrrolidone (NMP).The wholly aromatic polyimides have strong absorptions in the visible regions, because of their change–transfer complex formation. On the other hand, alicyclic dianhydride, H‐PMDA, contributed to the resulting Bco‐PI film with colorlessness and transparency, which are the important factors for a photosensitive polyimide. Photosensitive Bco‐PI, containing 20 wt % 1,2‐naphthoqiunonediazide‐5‐sulfonic acid p‐cresol ester (PC5), showed a sensitivity of 250 mJ/cm2 and a contrast of 2.56 when it was exposed to UV light, followed by development with 5% tetramethylammonium hydroxide (TMAH) aqueous solution at room temperature. © 2005 Wiley Periodicals, Inc.

Authors: Fan Lihong , Du Yumin , Huang Ronghua , Wang Qun , Wang Xiaohui , Zhang Lina 
Published: March 2005

AbstractAlginate and gelatin blend fibers were prepared by spinning their solution through a viscose‐type spinneret into a coagulating bath containing aqueous CaCl2 and ethanol. The structure and properties of the blend fibers were studied with the aid of infrared spectra, scanning electron micrography, X‐ray diffraction, and thermogravimetric analysis. Mechanical properties and water‐retention properties were measured. The best values of the tensile strength and breaking elongation of blend fibers were obtained when gelatin content was 30 wt %. The water‐retention values of blend fibers increase as the amount of gelatin is raised. The structural analysis indicated that there was strong interaction and good miscibility between alginate and gelatin molecules resulted from intermolecular hydrogen bonds. © 2005 Wiley Periodicals, Inc.

Cellulose derivative‐based cholesteric networks
Authors: Zhou Xuesong , Huang Yong 
Published: March 2005

AbstractEthyl‐cyanoethyl cellulose [(E‐CE)C]/acrylic acid (AA) solution could form cholesteric networks when the AA was quickly photopolymerized. The cholesteric structure in the solution was changed during the polymerization but the variation of the cholesteric order could be depressed by crosslinking of the system. The dependence of λmax for the cholesteric phase on both the crosslinker concentration and the polymerization temperature was studied by UV‐Vis spectrometry. It was found that the cholesteric pitch variation is decreased with increasing the concentration of the crosslinking reagent and the water sensitivity of the cholesteric network is effectively suppressed and dependent on the types of crosslinker. The pitch of cholesteric network was decreased sharply with increasing the polymerization temperature, due to the increase of the volume shrinkage of the solvent during the polymerization. © 2005 Wiley Periodicals, Inc.

Degree of branching of hyperbranched polystyrenes via a controlled radical mechanism of an inimer: Determination by a kinetic approach
Authors: Ishizu Koji , Ohta Yoshihiro , Kawauchi Susumu 
Published: March 2005

AbstractWe studied, with a kinetic approach, the living nature and degree of branching (DB) of the formation of hyperbranched polystyrene by the free‐radical photopolymerization of 2‐(N,N‐diethyldithiocarbamyl)methylstyrene in benzene. The free‐radical polymerization proceeded with a living radical mechanism. Subsequently, we treated the kinetics of the initiation and propagation steps of the active A* and B* (side‐group) sites with model compounds. The degradation rates of two types of dithiocarbamate groups at the A and B sites agreed well with theoretical trends for CS bond dissociation energies predicted by the density functional theory for model compounds. The reactivity of the initiating B* groups was greater than that of the propagating A* groups. DB of the hyperbranched polymers was estimated to be 0.31 with both reaction rates in terms of Müller's equation. This result supported the DB value (0.39) estimated from NMR data. The hyperbranched molecules obtained in this work were not perfectly dendritic but had somewhat defective structures. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 1810–1815, 2005
Wet‐phase‐separation membranes from the polysulfone/N,N‐dimethylacetamide/water ternary system: The formation and elements of their structure and properties
Authors: Stropnik Chrtomir , Kaiser Vladimir , Musil Vojko , Brumen Milan 
Published: March 2005

AbstractAsymmetric and porous polysulfone (PSf) membranes were prepared by wet phase separation. Binary (PSf)/N,N‐dimethylacetamide (DMA) solutions with polymer concentrations of 12.5–30 wt % were cast in thicknesses of 80–700 μm and immersed in a coagulation bath of pure water. The morphology of the formed membranes' cross sections consisted of a cellular structure and macrovoids; the cellular structure density was highest when the cast solution contained about 21 wt % PSf, regardless of the cast thickness. The membranes' pure water permeability decreased as the cast thickness increased. The instantaneous onset of the turbidity, regardless of the PSf content and cast thickness, its steep growth, and relatively high end value were the main characteristics of the turbidity phenomena taking place during the formation of the protomembranes. Again, the membrane‐forming system with a PSf/DMA solution with about 21 wt % polymer, regardless of the cast thickness, had the highest turbidity end value. The shrinkage of the cast solutions into the corresponding protomembrane was also examined quantitatively. Inverse experiments showed that the direction of the gravitation field had no influence on the shrinkage of the membrane‐forming ternary system or the membranes' morphology and its water permeability. © 2005 Wiley Periodicals, Inc.
