Centrality claims in the introduction part of a research article are aimed at attracting readers’ attention towards the research topic to be discussed in the article. Readers will decide whether or not to continue reading the article if the appeal is effective and the claims of the importance and usefulness of the article are accepted. However, most studies investigate only the discourse patterns and linguistic features of article introductions without analyzing further how authors attract readers’ attention to the importance of their research topic. This study aimed at comparing the types of centrality claims found in the introductions of articles published in high-rank and low-rank international journals in Applied Linguistics. Forty articles chosen from four Scopus-indexed international journals in Applied Linguistics were used in this study. The results showed that on average every article used 3.65 appeals of different types. Two types of claims (appeal to salience and appeal to problematicity) are more frequently used by authors than the other two types of appeal (appeal to topicality and appeal to magnitude). The data also reveal that, although not significant, the journal ranking correlates with the frequency of appeals used in the introductions. It is suggested that authors in Applied Linguistics should use multiple types of appeals in their introduction to attract readers’ attention to their research topic so that they are willing to read the entire article.
Asymptotic Optimality of Base-Stock Policies with Idle Times for Stochastic Economic Lot Scheduling Problems

We study the Stochastic Economic Lot Scheduling Problem (SELSP) which is concerned with the scheduling of production of multiple products by a common facility. Our goal is to characterize an optimal lot-sizing policy, with possible idle times inserted between productions, so as to minimize a long-run average holding, backlog, and setup cost. Due to its complexity, the optimal-control problem of SELSP is unsolved, with existing results mostly focusing on restricted classes of policies. In this paper, we take an asymptotic approach and prove that the classical base-stock policy with idle times is asymptotically optimal among a large class of admissible controls as the setup times grow large. Extensive numerical studies and computations of the optimal control in sufficiently simple cases (that can be solved using Markov decision processes) demonstrate the effectiveness and the robustness of the asymptotically optimal policy.

In vitro apical microleakage evaluation for different endodontic sealers by spectrophotometric analysis: an observational study

Background: It has been established that several filling techniques can affect apical leakage, which is responsible for 59% of endodontic failures. The primary goal of endodontic therapy is to create a tight seal that aids in repairing the periapical tissues, prevents apical periodontitis, and shields against root canal infection. The study aims to compare the apical sealing ability of epoxy resin based sealer (AH plus), which is an epoxy-resin-based root canal sealer, GuttaFlow 2, which is a silicone-based root canal sealer, GuttaFlow bioseal is a bioactive glass-based root canal sealer, TotalFill HiFlow bioceramic (BC) sealer is a silicate-based root canal sealer (bioceramic sealer) using a single cone technique by spectrophotometric analysis. Methods: This study chose 64 maxillary first molars with a straight palatal root. Following palatal roots sectioning to 11 mm from the root apex, the canals were instrumented up to size X4 using Protaper Next. They were separated into four experimental groups (n = 15) per each group based on the kind of sealer utilized, Group I: AH plus, Group II: GuttaFlow 2, Group III: GuttaFlow bioseal, Group IV: TotalFill BC HiFlow, and two control groups (n =2 for each). After completing obturation, the dye extraction technique was used to evaluate apical leakage. A spectrophotometer was used to measure the optical density of the solution after all the dyes were liberated from the interfacial regions. Result: A statistically non-significant difference between the investigated root canal sealers in apical microleakage P > 0.05 was noted. The highest mean values were observed in group IV (0.08046), group I(0.07731), and group II(0.06209), while the lowest mean value in group III (0.05719) Conclusions: All types of sealers used in this investigation showed various amounts of microleakage. None of the sealants could completely close the apical foramen to provide a fluid-tight seal.
Short communication: Potential of Sentinel 1 InSAR and offset 1 tracking in monitoring post-cyclonic landslides activities in 2 Reunion Island. 3

12 This study examined the results of an interferometric Synthetic Aperture Radar (InSAR) and SAR Offset Tracking 13 (OT) study on Cirque de Salazie (CdS), Reunion Island, France, within the context of the RENOVRISK project, 14 a multidisciplinary programme to study the cyclonic risks in the South-West Indian Ocean. CdS is one of the 15 denser populated areas in Reunion Island. One of the aims of the project was to assess whether Sentinel 1 SAR 16 methods could be used to measure landslide motion and/or accelerations due to post cyclonic activity on CdS. We 17 concentrated on the post 2017 cyclonic event. We used the Copernicus Sentinel 1 data, acquired between 18 30/10/2017 and 06/11 2018. Sentinel 1 is a C-band SAR, and its signal can be severely affected by the presence 19 of changing vegetation between two SAR acquisitions, particularly in CdS, where the vegetation canopy is well 20 developed. This is why C-band radars such as the ones onboard Radarsat or Envisat, characterized by low 21 acquisition frequency (24 and 36 days, respectively), could not be routinely used on CdS to measure landslide 22 motion with InSAR in the past. In this study, we used InSAR and OT techniques applied to Sentinel 1 SAR. We 23 find that C-band SAR onboard Sentinel 1 can be used to monitor landslide motion in densely vegetated areas, 24 thanks to its high acquisition frequency (12 days). OT stacking reveals a useful complement to InSAR, especially 25 in mapping fast moving areas. In particular,
Small pelagic marine fisheries for food sovereignty? The case of the dagaa fishery at three coastal sites in Tanzania

To implement effective ocean governance, development of policies and management strategies needs to incorporate input from communities that will be impacted by the decisions. People engaging in small-scale fisheries and aquaculture mobilize themselves in anticipation of various challenges, for example, food sovereignty. Food sovereignty is the right for people to access healthy and culturally appropriate food that is produced through ecologically sound and sustainable methods. Little attention has been paid to documenting and understanding the struggles and efforts of small-scale fishers to ensure their own food sovereignty. In the Western Indian Ocean region, and Tanzania in particular, there has been a limited number of initiatives among coastal fishers that seek to transform food systems. To better understand these initiatives, this study was designed to examine collective actions undertaken in pursuit of food sovereignty among small pelagic fishers at three landing sites on the coast of Tanzania. Collection of primary data involved a survey of 206 individuals, 25 key informant interviews, 3 focus group discussions and participant observation. Secondary data was also collected from official fisheries records and published materials to supplement the primary data. The study revealed limited current capacity of the small pelagic fisheries to satisfy local demand of fifish for food security and sovereignty purposes due to increased fish trade supplying markets beyond the study sites. The prospects of satisfying an increasing fish demand from existing production systems are limited. Small pelagic fisheries need to be linked to the global food system through appropriate mechanisms to allow them to contribute meaningfully to food security and sovereignty.
A microcontroller-based system for piezoscanner nonlinearity correction: Atomic force microscope

Scanning probe microscopes use piezoelectric actuators (piezoscanners) as extremely sensitive and exact positioners for small scaled sample scannings. They are capable of making fine movements along the X, Y, and Z axes, with displacements that can vary from several hundreds of angstroms to some micrometers. For high amplitude sweeps, the displacement response results in visible distortions due to the intrinsic nonlinearity effects of the piezoelectric tube. This work proposes the nonlinearity correction by means of a microcontroller-based system which produces (in real time) the correction values using the piezoscanner quadratic transfer function, adapted to an atomic force microscope (AFM) of its own construction. The AFM is intended to be used with biological samples. Other correction methods are described.
Nanocellulose-Based Polymer Composites Functionalized with New Gemini Ionic Liquids

The manuscript discusses the application of dimeric imidazolium ionic liquids with an aliphatic linker of different lengths, constituting a new class of compounds called gemini, for the modification of renewable materials. This innovative functionalization with the use of ionic liquids made it possible to obtain polymer composite nanomaterials with renewable fillers, which will reduce the consumption of petroleum-based raw materials and also be directly related to the reduction of energy intensity. Renewable filler in the form of nanocellulose modified with ionic liquids, as well as polymer composites with such filler obtained by extrusion and injection molding techniques, were subjected to detailed characterization using techniques like: X-ray diffraction (XRD), Fourier transform spectroscopy (FTIR), dispersion studies (DLS), morphological analysis (SEM), differential scanning calorimetry (DSC), hot-stage polarized light microscopy and characterization of mechanical properties. The use of innovative dimeric ionic liquids proved to be an effective method to carry out efficient functionalization of cellulose. This provided a stable space structure between polysaccharide particles, limiting aggregate formation. It was shown that chemical modification with ionic liquids has a significant effect on the nucleation activity of cellulose fillers and the formation of the supermolecular structure of the polymer matrix, which consequently allowed to obtain polymer composites with excellent strength characteristics and increased flexibility, which will allow to increase their application potential. Innovative ionic liquids have contributed to obtaining green nanomaterials with excellent functional properties, which have not been described in the literature so far.
Coupled‐Wave Theory of Distributed Feedback Lasers

An analysis of laser action in a periodic structure is presented. A model of two counter‐running waves coupled by backward Bragg scattering is used. The resonant frequencies and threshold criteria for the modes of oscillation have been determined for both index and gain periodicities. Analytical approximations are given for both the high‐ and low‐gain cases, and computational results for the intermediate regimes.
Recovery of North Island kākā (Nestor meridionalis septentrionalis) within Pureora Forest Park, 2000–2020

: To test the long-term efficacy of mammalian pest control, annual distance sampling estimates of the density of North Island kākā ( Nestor meridionalis septentrionalis ) within the southern Waipapa Ecological Area (WEA), Pureora Forest Park from 2008–2020 are compared to previously published estimates made at the same sites and time of year (October) between 2000–2007. Kākā density increased approximately four-fold from an average of c. 0.5 (95% CI 0.5–0.6) birds ha −1 between 2000 and 2007 to c. 2.3 (95% CI 1.9–2.8) birds ha −1 in 2020. The average of rate of increase between 2000 and 2018 was c. 6.9% per annum. Kākā recovery is likely to be a function of multiple mast events and long-term (> 20 years), large-scale, frequent, effective control of possums ( Trichosurus vulpecula ) and probably mustelids. It is recommended that the current pest control as well as kākā and pest monitoring continue.
Understanding the Potential Gene Regulatory Network of Starch Biosynthesis in Tartary Buckwheat by RNA-Seq

Starch is a major component of crop grains, and its content affects food quality and taste. Tartary buckwheat is a traditional pseudo-cereal used in food as well as medicine. Starch content, granule morphology, and physicochemical properties have been extensively studied in Tartary buckwheat. However, the complex regulatory network related to its starch biosynthesis needs to be elucidated. Here, we performed RNA-seq analyses using seven Tartary buckwheat varieties differing in starch content and combined the RNA-seq data with starch content by weighted correlation network analysis (WGCNA). As a result, 10,873 differentially expressed genes (DEGs) were identified and were functionally clustered to six hierarchical clusters. Fifteen starch biosynthesis genes had higher expression level in seeds. Four trait-specific modules and 3131 hub genes were identified by WGCNA, with the lightcyan and brown modules positively correlated with starch-related traits. Furthermore, two potential gene regulatory networks were proposed, including the co-expression of FtNAC70, FtPUL, and FtGBSS1-3 in the lightcyan module and FtbHLH5, C3H, FtBE2, FtISA3, FtSS3-5, and FtSS1 in the brown. All the above genes were preferentially expressed in seeds, further suggesting their role in seed starch biosynthesis. These results provide crucial guidance for further research on starch biosynthesis and its regulatory network in Tartary buckwheat.
A New Strategy for Achieving Shape Memory Effects in 4D Printed Two-Layer Composite Structures

In this study, a new strategy and design for achieving a shape memory effect (SME) and 4D printed two-layer composite structures is unveiled, thanks to fused deposition modeling (FDM) biomaterial printing of commercial filaments, which do not have an SME. We used ABS and PCL as two well-known thermoplastics, and TPU as elastomer filaments that were printed in a two-layer structure. The thermoplastic layer plays the role of constraint for the elastomeric layer. A rubber-to-glass transition of the thermoplastic layer acts as a switching phenomenon that provides the capability of stabilizing the temporary shape, as well as storing the deformation stress for the subsequent recovery of the permanent shape by phase changing the thermoplastic layer in the opposite direction. The results show that ABS–TPU had fixity and recovery ratios above 90%. The PCL–TPU composite structure also demonstrated complete recovery, but its fixity was 77.42%. The difference in the SME of the two composite structures is related to the transition for each thermoplastic and programming temperature. Additionally, in the early cycles, the shape-memory performance decreased, and in the fourth and fifth cycles, it almost stabilized. The scanning electron microscopy (SEM) photographs illustrated superior interfacial bonding and part integrity in the case of multi-material 3D printing.

Improved antimicrobial activity of Zinc-Oxide Nanoparticles in peritoneal dialysis fluid using Silk Fibroin Protein coating

ABSTRACT Bacterial infections in the abdominal area are a primary cause of complications in patients with renal failure who are on peritoneal dialysis (PD). To combat such infections, Zinc Oxide (ZnO) Nanoparticles (NPs) are gaining popularity because of their well-known antibacterial characteristics. However, due to their quick accumulation and generation of bio-conjugates upon interaction with the components of PD Fluid, surface modification is required. In this context, the current study’s aim was to coat the ZnO-NPs with Silk Fibroin (SF) protein and assess their stability in PD fluid. UV-vis spectroscopy, Proton Nuclear Magnetic Resonance (1 H NMR) spectroscopy, Scanning electron microscopy (SEM) and Dynamic Light Scattering (DLS) characterisations, all validated the stability of SF-coated ZnO-NPs in PD fluid. Furthermore, SF-coated ZnO-NPs were tested as an antibacterial agent against Staphylococcus aureus, and our findings demonstrated that SF-coated ZnO-NPs significantly suppressed S. aureus activity.
Integrated coaxial-hollow micro dielectric-barrier-discharges for a large-area plasma source operating at around atmospheric pressure

An integrated structure of coaxial-hollow micro dielectric-barrier-discharges has been developed by stacking two metal meshes covered with insulating material. The test panel has an effective area of 50 mm diameter in which hundreds of hollow structures are assembled with a unit hollow area of 0.2 × 1.7 mm2. He or N2 was used as the discharge gas in the pressure range from 20 to 100 kPa and the firing voltage was less than 2 kV, even at the maximum pressure. The intensity of each microdischarge was observed to be uniform over the whole area throughout the pressure range, and its time evolution during one discharge pulse was analysed through two-dimensional microscopic observation with a gated CCD camera. In a gas flow regime through the coaxial hollow structures, several significant changes of the discharge properties were observed, such as impurity reduction, decrease in discharge voltage and cooling of the neutral gas. The fundamental plasma parameters were measured using a single probe in the downstream region of microdischarges using an auxiliary flat electrode set apart from the mesh electrode plane. The occurrence of an extended glow with a length of some millimetres was observed in He but not in N2. The electron density derived by the probe data in He at 100 kPa was ∼3 × 1011 cm−3, suggesting a value of more than 1012 cm−3 in the active microdischarge region.
IS CONTRACEPTIVE INJECTION CAUSE BREAST CANCER? : META ANALYSIS

Background: Injectable hormonal contraception was a major risk factor for breast cancer. The content of the progestin hormone in injection hormonal contraceptives can affect the uncontrolled growth of breast tissue, leading to breast cancer. This study aims to analyze the magnitude of the effect of injection hormonal contraception on the incidence of breast cancer with a meta-analysis study. Method: This research is a systematic review and used a Prisma flow diagram. The process of searching for articles through a database of journals which includes: PubMed, Science Direct, and Google Scholar by selecting articles published in 2010-2020. Keywords used include: “ Women Aged 15-80 Years” OR “Women of Menopause” AND “Birth control injections” AND “Breast Cancer”. The inclusion criteria included full-text articles with a case-control study design, articles using English, and multivariate analysis with adjusted odds ratios. Artikel fulfills the requirements for analysis using Revman 5.3 Result: There were 6 articles with the case-control study. A meta-analysis of 6 case-control studies showed that the use of injectable hormonal contraception had a 1.37 times risk of developing breast cancer compared with women using non-hormonal contraception (aOR 1.37; 95% CI 1.09 to 1.71; p = 0.006). Conclusion: Injectable hormonal contraceptives can increase the incidence of breast cancer.
Subcategorisation, not uncertainty, drives the modification effect

The modification effect refers to the finding that likelihood ratings for statements using modified concepts (e.g., baby ducks have webbed feet) are lower than for statements using the unmodified head concept (e.g., ducks have webbed feet). One explanation for this effect is that people are reluctant to attribute properties to a combined concept due to general uncertainty about the combined concept. Across four experiments, we examined three sources of uncertainty (i.e., modifier, relational structure and category membership) and found that reducing uncertainty does not remove the modification effect. In addition, the results demonstrate that the modification effect is not unique to decisions concerning combined concepts, but extends to single-name subcategories. The results of these experiments indicate that the modification effect results from inferences based on meta-knowledge about category–subcategory relations.
