Excessively Tilted Fiber Grating Sensors

The development of excessively tilted fiber gratings (Ex-TFGs) provides a new type of sensing device with high refractive index (RI) sensitivity, low thermal crosstalk and vector sensing property. Due to the asymmetric grating structure of Ex-TFG, the light in the core is coupled into high order forward-propagating cladding modes and split into two orthogonal polarization states, resulting in dual-peak resonances in the transmission spectrum. The Ex-TFG also exhibits a non-circularly symmetrical near field distribution, which endows an exceptional orientation sensing capability. Benefitting from the unique mode coupling behavior, Ex-TFGs have been studied and developed for many different sensing applications, such as polarization dependent torsion and loading sensors, vector accelerometer and magnetometer, and a variety of low thermal crosstalk bio/chemical sensors. This paper will review the recent study and development of Ex-TFGs in terms of mode coupling mechanism, fabrication method, transmission and sensor characteristics and the novel applications in sensing areas.
Artemisinin-passivated mixed-cation perovskite films for durable flexible perovskite solar cells with over 21% efficiency

High power conversion efficiencies (PCEs) surpassing 20% have been achieved on flexible single-junction perovskite solar cells recently. However, improvements of the open-circuit voltage (VOC) and fill factor (FF), limited by the nonradiative recombination, and the device durability are needed to boost the practical performance further. Herein, we report the use of artemisinin, an herb extract, to passivate the perovskite grains to improve the VOC and FF of flexible PSCs significantly. The incorporation of artemisinin (0.22 mol%) in the perovskite film reduces the film's trap density and thus the nonradiative recombination effectively. As a result, a best PCE of 21.10% is achieved, comparable with state-of-art values of flexible thin-film solar cells (CIGS, CdTe, etc.). VOC reaches 1.126 V, corresponding to a VOC loss of 0.437 V. Moreover, the flexible PSCs incorporated with artemisinin always exhibit excellent stabilities under different aging conditions. Strong interactions between the artemisinin molecules and the uncoordinated Pb2+ ions revealed by theoretical and experimental calculations are responsible for the suppressed formation of new deep-level trap defects, Pb clusters, upon aging.
Effect of different altitudes on milk fatty acid and conjugated linoleic acid (CLA) profiles

Geographical position and feed quality of farms in highland and lowland, particularly in the tropical region, cause the differences in milk quality. One of the factors that influenced milk quality is the fatty acid (FA) profile of milk. The objective of this study is to compare the FA profiles of milk produced by farms in highland and lowland regions. Milk sampling was done by random purposive method at two regions which have different altitudes. Milk sampling was conducted with 28 farmers whose cows were fed botanically diverse forages and with commercial mix concentrate of dairy cows. The FA profiles of the milk samples were analyzed using Gas Chromatography (GC-7820A/G4350B, Agilent Technologies). Individual FAME was identified by comparison to standard mixture Supelco 37 Component FAME Mix and standard CLA (O5507, Sigma-Aldrich). The FA profiles were statistically analyzed for normality test and t-test carried out by SPSS ver.22. There were nine significantly different FA profiles consisting of C6:0, C10:0, C12:0, C14:0, C16:0, C18:0, C18:1-trans9, C18:2-trans, C18:2-cis, and C18:2-CLA. The milk from the lowland region has higher PUFA content, especially CLA content, and also has lower SFA content. The conclusion is milk from highland and lowland regions consists of different FA profiles.

A review on the prospect of wind power as an alternative source of energy in Malaysia

Fossil fuels has dictated the energy sector for several decades, rising as the primary and prominent source of energy production for various sector of industries namely electricity (power), transportation, manufacturing and others. However, extensive usage of fossil fuels majorly contributed to pollution issues and degradation of the environment. Hence, governments and research agencies are providing supports and resources to facilitate the growth of renewable energy sector (RES). This manuscript provides a brief view of the challenges of wind renewable energy sector in Malaysia relative to geographical wind condition, government policies and challenges in initiation of wind technologies and global perspective of green energy in terms of RER. It is found that data presented by previous researchers on wind speed data are considered unreliable to be utilized for WT power density assessment and design. Notably, wind speed in Malaysia is seasonal based and highly inconsistent. The wind flow pattern and intensity experience by Malaysia are merely an aftereffect of weather change in neighbouring regions. Nevertheless, it is found that selected regions of east-coast peninsular Malaysia and selected region of Sabah and Sarawak is potential for harvesting wind power due to substantial and adequate wind pattern behavior during monsoon season. Therefore, it is evident that geographical wind condition of Malaysia is appropriate for wind power devices as a form of RER in green energy sector of Malaysia. However, it is also found that fundamental design modification is required on conventional design of WT in terms of blade morphology and configuration in order to adapt to unsteady monsoon wind speed pattern.
Communicating about Alzheimer’s disease: Designing and testing a campaign using a framing approach

Abstract The prevalence of negative representations of Alzheimer’s disease (AD) reinforces the stigma and negative attitudes toward this dementia. To mitigate these negative views, campaigns have been launched by several organizations. This study aims to explore the effect of framing in AD campaigns on attitude change. For this purpose, several posters were designed with framed messages defining dementia (dualism, unity, and control) and 189 participants were shown the posters. In order to analyze the effect of the different frames, a repeated-measures design was used, in which attitudes toward dementia were measured three times. The impact of the campaign and the emotions it produced were recorded as well as the effects of the participants’ experience with AD and the importance they attached to it. Posters with unity-framed messages produced a positive and lasting change in attitudes toward dementia and higher levels of happiness, while dualism-framed messages had a greater impact and produced feelings of sadness, anger, and fear but did not change the audience’s attitude. Although more research is needed on persuasion in campaigns, the findings can serve to guide the design of AD campaigns.
In vitro degradative effect of purified zearalenone with or without adsorbents after bionic digestion

Zearalenone (ZEN) is a nonsteroidal estrogenic mycotoxin mainly produced by Fusarium graminearium and Fusarium culmorum found in various host plant-soil debris worldwide, causing hyperestrogenism and related toxicoses in farm animals and humans. ZEN is present as a contaminant in cereals such as maize, barley, wheat, rice, oats, rye, and sorghum (Pittet, 1998; Tanaka et al., 1988), as well as in processed cereal-based food such as flakes and bread (Betina, 1989; Aziz et al., 1997), corn pancakes (Groves et al., 1999), and beer (Martin & Keen, 1978; Okoye, 1987).

Growth and characterization of In2O3 thin films prepared by pulsed laser deposition

The effect of growth temperature and oxygen partial pressure on growth as well as electrical and optical properties of intrinsic indium oxide (In 2 O 3 ) thin films was studied. High quality thin films were grown on quartz substrate by pulsed laser deposition (PLD) technique. Optical transmittances as well as electrical parameters such as electrical resistivity, carrier concentration, and mobility of these films depend on both oxygen pressure and growth temperature. A detailed study indicates that the films which are highly conducting and transparent correspond to an optimum growth temperature of 400 °C and an oxygen partial pressure of 1 × 10 -6 bar. Higher transmittance (-90%), lower electrical resistivity (1.7 × 10 -4 Ω.cm), and higher mobility (119 cm 2 V -1 s -1 ) of PLD grown intrinsic In 2 O 3 films compared with tin doped indium oxide (ITO) suggest that PLD grown In 2 O 3 could be an excellent material for optoelectronic applications.
Research on the correlation between colorectal adenoma and sucrase-isomaltase based on constitution theory

Intestinal cancer is one of the common malignant tumors in the digestive system. Colorectal adenoma is closely related to colorectal cancer, which seriously threatens people’s health. This study selected colorectal adenoma tissue samples from patients with different traditional Chinese medicine constitutions as experimental objects, and used Sucrase-isomaltase (SI) as a marker to perform the research: the expression of SI in different samples; SI separation and purification; SI biochemical characteristic detection; the difference in the expression and characteristic of SI, supplemented by database analysis. The constitution susceptible to colorectal adenoma is mainly Yang deficiency type, followed by blood stasis type. It is expected to establish the relationship between SI and colorectal adenoma and traditional Chinese medicine constitutions.
Financial reporting and macroeconomics

Financial Reporting (FR) is a fundamental source of information for the correct functioning of markets. Traditionally, FR is associated with the communication activity done by firms to inform stakeholders and the general public about their financial performance. In the first and second part of this essay, I revisit some of the channels through which firm-level FR affects the macroeconomic environment. However, companies are not the only economic actors that engage in an FR activity. Local and national governments produce financial reports as well. In the third part of this essay, I review how we can use the theoretical framework developed for firm-level FR to study government-level FR. I conclude by highlighting the importance of incentives as the fundamental mediator of the relationship between FR and Macroeconomics. I remark how they shape different FR environments during crisis and non-crisis periods and the importance of taking these differences into account while regulating and supervising markets.
To Post or Not to Post? Factors Influencing State FFA Officers’ Social Media Behaviors

The demand for agriculture, food, and natural resource (AFNR) messages to be conveyed via channels of social media provides a natural inclination to seek out digital natives, such as state FFA officers, to fill the present gap of agriculturalists in online environments. The purpose of this study was to examine the factors that influence state FFA officers’ behaviors of communicating about AFNR issues on social networking sites. The theoretical framework that guided this study of communication behaviors was the theory of planned behavior. A census of the accessible population of 276 state officers was attempted, and 97 usable responses were received (35.1%). The findings reinforced the use of the theory of planned behavior to understand, predict, and change AFNR social media behaviors. The significance of subjective norms suggested that online AFNR communication is mainly under subjective control for state FFA officers. To increase online engagement of state FFA officers, it is recommended that behavioral change efforts target normative beliefs and that clear behavioral expectations are expressed. Further research is recommended to determine if the significance of subjective norms as a predictor of intent is unique to technological and social media behaviors or applicable to a broader context. Additional research with other populations of young agriculturalists is also recommended.
Parents' preferences for preventive and curative dental services: A comparison between fissure sealant and composite filling using willingness-to-pay method.

BACKGROUND The early years of life play a significant role in the lifelong health of humans and parents have an important role in healthcare decision making. Thus, it seems necessary for policymakers and clinicians to be aware of how parents value pediatric health services. Willingness to pay (WTP) is a recommended method for measuring the stated utility of health services/goods or health states. AIM This study aimed to elicit and compare parents' WTP for health services such as fissure sealant and composite filling. DESIGN An originally developed questionnaire was used to guide interviews with a sample of 290 parents attending a public pediatric healthcare center. Related-samples Wilcoxon signed-rank test was performed for comparing the difference in absolute WTP amounts between the two services, and linear regression was used to assess the association between WTP and relevant variables using SPSS version 21. RESULTS Mean WTP for fissure sealant and filling was 269 724 and 555 327 Tomans, respectively, and the difference between them was statistically significant (P < .001). Higher WTP amounts found in both services were associated with income levels of 4 and 5 (P < .05). CONCLUSIONS Respondents highly valued the considered services and stated a significantly higher relative preference for filling. Public awareness should be promoted about the importance of prevention of oral health diseases and the attributes of the oral healthcare system services.
Construction of Meteorological Simulation Knowledge Graph Based on Deep Learning Method

With the maturity of meteorological simulation technology, the research literature in this field is undergoing a rapid increase. The published literature can provide useful guidance for current research to get scientific results; however, it tends to be rather time consuming to obtain exact knowledge from massive literature, and it is necessary to transform the literature into structured knowledge to meet the efficient management, sharing, and reuse of meteorological simulation knowledge. In this paper, methods of meteorological simulation knowledge extraction and knowledge graph construction are proposed. A deep learning model based on bilateral long short-term memory-conditional random field (BiLSTM-CRF) is used to extract the meteorological simulation knowledge from the massive literature. Then, the Neo4j graph database is used to construct the meteorological simulation knowledge graph. Based on the meteorological simulation knowledge graph, it can realize the structured storage and integration of meteorological simulation knowledge, which can bridge the gap in the transformation of massive literature to sharable and reusable knowledge. Furthermore, the meteorological simulation knowledge graph can be used as an expert resource and contribute to sustainable guidance and optimization for meteorological simulation research.
An Image of Encryption Algorithm Using Graph Theory and Speech Signal Key Generation

In this paper, a color image of encryption algorithm used a graph theory has been proposed. The proposed algorithm depends on the audio files as a basis for exploiting a set of keys for encoding color images. The key generation system was built by passing the audio signal in several stages based on the graph theory. The results revealed that the proposed algorithm has generated the encrypted images with uniform distribution in pixel histograms with information entropy closes to 8, which resists different attacks. The comparison experiments with other recent algorithms were performed. The statistical results show that the proposed algorithm has a strong security against attacks.
Assessment of Ecological Condition of Haplic Chernozem Calcic Contaminated with Petroleum Hydrocarbons during Application of Bioremediation Agents of Various Natures

Petroleum hydrocarbon contamination disrupts ecological and agricultural soil functions. For their restoration, bioremediation agents of various natures are used (nonorganic or organic fertilizers, bacterial preparations, adsorbing agents) featuring different remediation mechanisms (adsorption or biostimulation of petroleum hydrocarbon decomposition). The objective of this research is the assessment of the ecological condition of petroleum hydrocarbon-contaminated Haplic Chernozem Calcic after the application of bioremediation agents of various natures. The influence of glauconite, nitroammophos, sodium humate, the bacterial preparation “Baikal EM-1”, and biochar on the intensity of petroleum hydrocarbon decomposition and the ecological condition of Haplic Chernozem Calcic was analyzed. The ecological condition of Haplic Chernozem Calcic was assessed based on the residual content of petroleum hydrocarbons in soil and the following biological parameters: changes in the number of soil bacteria, activity of catalase and dehydrogenases, soil respiration (CO2 emission), germinating ability, lengths of roots and shoots, and integrated index of the biological state. The minimum concentrations of residual petroleum hydrocarbons in soil were observed after the use of biochar (44% from initial content) and glauconite (49%). The biological properties of soils were affected in different ways. Soil respiration was stimulated by 3-6-fold after adding nitroammophos. Indices for the intensity of the early growth and germination of radish in soil with glauconite, sodium humate, and biochar were increased by 37–125% (p < 0.01) compared with the reference value. After the application of biochar, sodium humate, and “Baikal EM-1”, the number of soil bacteria was 66–289% higher (p < 0.01) than the reference value. At the same time, the activities of catalase and dehydrogenases were inhibited by up to 35% in variants with bioremediation agents and petroleum hydrocarbons relative to the reference values. The maximum stimulation of the biological activity (as the integrated index of the biological state (IISB)) of Haplic Chernozem Calcic was observed after applying sodium humate and biochar, with 70 and 66% (p < 0.01) increases from the reference value, respectively. Considering the net cost of bioremediation agents, the maximum cost efficiency is achieved with “Baikal EM-1”, sodium humate, and biochar: 110, 527, and 847 USD·103/ha, respectively. After using Baikal EM-1”, sodium humate, and biochar, the ecological state of Haplic Chernozem Calcic was restored.
