Authors: Zhong Tuhua , Jian Guoqing , Chen Zhen , Wolcott Michael , Nassiri Somayeh , Fernandez Carlos A. 
Published: July 2022

AbstractNanomaterials have been widely researched for use in construction materials. Numerous studies demonstrate that nanomaterials in small quantities can significantly improve the macroscopic properties of cement paste, mortar, or concrete through various mechanisms. Nanomaterials retrieved from biomass sources have recently gained particular research interest due to remarkable structural properties and the source material’s abundance and renewability. Cellulose and chitin are the most abundant polysaccharides in nature; thus, they are candidates for nanomaterials extraction as multifunctional additives in cementitious systems. In recent years, cellulose nanomaterials in cementitious composites have been extensively investigated, but chitin nanomaterials and starch derivatives for cement and concrete are still emerging research areas. This review article starts with an overview of polysaccharide nanomaterials’ (PNMs) physicochemical properties as a result of different chemical and mechanical extraction processes. Next a brief overview of cement hydration chemistry and microstructure and the interfacial interactions between the cement and the various surface chemical functionalities of PNMs are discussed. Then, the key mechanisms governing the cement strength enhancement by PNMs, such as bridging, nucleating and filling effect, and internal curing, are described. Finally, the impacts of PNMs on other properties of the cement are discussed.

Abstract
Peruvian regions for sugarcane planting produce sugarcanes throughout the year with a high average productivity. The objective of this article is to analyze the role of agents in the sugarcane supply chain to Peruvian mills and their relationship with the practice of agrarian contracts to sugarcane production. The perception of landowners and farmers about bioenergy and their predisposition to plant energy crops is also investigated. Field interviews are conducted with the main agents of the sugarcane production chain in the major producing regions. Statistical analysis of data from field interviews indicates that the relationship between owners and sugarcane producers is of land leasing. Intermediate agents act as a fundamental part of the sugarcane supply chain. The sharecropping or sugarcane purchase contract is an instrument that is established between middlemen and small independent producers, whether they are owners or tenants. The middlemen participation in commercialization can reach 30–40% of the sugarcane production. Most mills prefer to produce sugarcane in own lands. A relatively high degree of inequity in favor of the middlemen appears in the intermediation process because, in general, the mills prefer this intermediation in their commercial practice. A large number of landowners and tenants are familiar with notions of energy crops, particularly in relation to sugarcane and have a positive vision about them for the environmental sustainability. However, their interest in planting bioenergy crops is less. Friendly and equitable relations between agents will provide more economic and social stability to the Peruvian sugarcane agroindustry.

Utilización político-mediática de conceitos sociolingüísticos na linguaxe actual
Authors: García Negro María Pilar 
Published: July 2022

Todo avanzo efectivo no proceso de normalización dunha lingua nacional submetida ao dominio da oficial estatal vai estar sempre acompañado-combatido por un arsenal semántico-terminolóxico que visa destruílo ou neutralizalo. A estratexia da imposición das linguas consideradas indiscutíbeis nas súas prerrogativas dotarase de tácticas diversas, adaptadas ao momento histórico e á súa maior eficacia divulgativa. Nesta operación da neoimposición das linguas estatais, utilízanse conceitos ou expresións que non se compadecen coa orixe histórica nen coa realidade sociolingüística. Interesa, pois, analisar a utilización xurídico-política —e a súa derivada mediática— de nocións como lingua común, conflito lingüístico, inmersión, plurilingüísmo ou normalización. Referímonos, en concreto, ao marco español, e ás linguas nacionais que del dependen: galego, éuscaro, catalán. A cuestión das linguas —o seu uso xeral, os seus dereitos, a súa existencia, en definitiva— está intimamente unida ao recoñecemento ou non dos povos, das sociedades a que pertencen. É, pois, unha cuestión esencialmente política, en que está en xogo a admisión ou non —en igualdade democrática e horizontal— de nacións que non posúen institucións estatais ao seu servizo. Na fase actual de capitalismo globalizado, dereitos democráticos teoricamente proclamados fican en entredito pola imposición de facto das linguas que contan de vello cunha maquinaria potente de implantación e consolidación social e pública. A título de exemplo significativo, sinalamos o incumprimento da Carta Europea das Linguas Rexionais ou Minoritarias, recoñecida como paralexislación polo Estado español en 2001 ou da Declaración Universal dos Dereitos Lingüísticos, aprobada por unanimidade polo Congreso de Deputados español e polos Parlamentos galego, basco e catalán en 1996.

The 'Flipped' Classroom - A Method for Improving Teaching and Learning Even in Large Classes
Authors: Urban Michal 
Published: July 2022

The Covid-19 pandemic has forced many of us to transform our approach to teaching and learning. Instead of standing in front of a class in the lecture hall or sitting around a table and interactively debating with students, we, as teachers, have found ourselves staring at students (or just their names) through such platforms as Zoom or Teams and overcoming the instances of hesitance or silence by, well, talking more. Sooner or later some, perhaps many, of us recognised this “trap of silence” and in searching for better approaches to online teaching began to use – intentionally or not – the flipped classroom method. In this text, I will share my experience from the spring semester of 2021, in which I used the flipped classroom method in a large group setting (over 150 enrolled students).
In the first part of this text, I will describe the course and implementation of the method. Then I will summarize its advantages and disadvantages and identify questions for further consideration. Throughout the paper, I include the experience of other teachers from the field of law and other disciplines to provide more context for my experience with the flipped classroom.

Introduction: The maternal mortality remains high in developing countries such as Indonesia. Three most common reasons for this incidence are hemorrhage, infection, and eclampsia. Some of these conditions can be infl uenced by Iron Defi ciency Anemia (IDA). A lot of programs for nutrition have been provided by Indonesian government, but the nutritional condition of pregnant women still be big problem in Indonesia. This study explored the nutritional status of pregnant village women in Banten Province, Indonesia and assessed interventions in dealing with nutrition problems among pregnant women especially in the rural area. Methods: The design was a longitudinal descriptive study with operational study by empowering village midwives and cadre to intervene pregnant women nutrition in rural area. The measurements were focused on the rate of anemia, body mass index (BMI), and weight. Three stages were applied in this study with community development as intervention. Results: This study reported some changes in the midwife practises after Intervertion, while cadres more talkative when explaining about nutrition after intervention. However, the intervention did not affect the overall nutritional status of the pregnant women and the intervention was not able to influence the community’s health in the medium term in the intervention villages. Conclusion: This study recommend the government and educational institutions to improve the competencies of health care providers especially in communication skill.

Abstract
Shale gas resources in mainland China and its commercial exploitation has been widely focused on the Wufeng–Longmaxi Formation organic-matter-rich shale in the Sichuan Basin. However, whether southwestern margin of the Sichuan Basin can produce high-quality shale gas has not been well resolved, which might be related to the poor understanding of the relationship between Cenozoic tectonic deformation and shale gas preservation. To answer the aforementioned scientific question, we conducted a detailed work in the Mugan area to show geologic structures and gas contents in the area through seismic profiles and geochemistry analysis. Specifically, the stable Mugan syncline shows a high gas content (&gt;2.6 m3/t measured at three boreholes D1, D2, and D3), whereas its periphery presents a poor gas content (about 0.6 m3/t measured at two boreholes X1 and Y1). Moreover, oblique fracture density and dissolved pores are much higher at boreholes X1 and Y1 than that at the other three boreholes. We propose an opposite-verging thrust fault model to explain the different gas contents and tectonic features in the Mugan area, which might indicate that regions in the southwestern Sichuan Basin with similar tectonic and stratigraphic characteristics as those in the Mugan syncline are likely to produce high-yield shale gas. This finding provides new insights into the exploration theory of shale gas in the Tibetan Plateau.
Implementation and Validation of Parasitic Stub Integrated Reconfigurable Polarization in Antennas
Authors: YADAV AJAY Kumar Singh , Yadav Rajendra Prasad 
Published: July 2022

Abstract
This proposed work presents a single feed radiating patch loaded with two parasitic stubs to achieve antenna polarization diversity. The primary antenna is a circular/square metallic patch with a rectangular slotted Defected Ground Structure (DGS), and it resonated at 5.5 GHz with Linear Polarization (LP). The Circular Polarization (CP) is achieved through quarter wavelength parasitic metallic stubs attached with a radiating patch using two PIN diodes which reconfigure the antenna for left hand CP (LHCP) and right-hand CP (RHCP) performances. The antenna is reconfigured its polarization modes between LP, RHCP, and LHCP by utilizing diodes switching configurations. Two antennas, a circular and a corner truncated square patch with parasitic stubs, are investigated to validate the concept of Circular Polarization (CP) using a quarter wavelength stub, and corresponding results are presented. The proposed antennas are printed on an RT/Duroid 5880 dielectric with a thickness 0.8 mm, and it provided a satisfactory agreement between measured and calculated results. The circular and square-shaped antennas have impedance bandwidth of 5.23-5.75 GHz (9.45%) for S11 less than -10dB, and measured axial ratio bandwidth (ARBW) for 3dB is approximately 5.4%.

Published: July 2022

Abstract
The issue of climate warming caused by greenhouse gases is an important practical issue. This researchaims to explore the impact of vertical fiscal imbalance (VFI) on CO2 emissions from the perspective of theoreticalanalysis and empirical research. This study uses panel data from 30 provinces in China from 2004 to 2018 to test thisissue. Results show that VFI has a significant positive impact on CO2 emissions and that capital misallocationexacerbates the positive impact of VFI on CO2 emissions. These research results also have significant temporalheterogeneity. In the sample results after 2008, the results are more significant. These conclusions provide aneconomic and political reference for local governments to achieve CO2 neutrality and CO2 peaking policy goals andto promote in-depth reform of the fiscal system.

Abstract
Background: The older adult population is increasing and depression is commonly observed within this community. This study is one of the firsts assessed depression and its risk factors in a healthy well-nourished over-55 years old population.Method: Beck Depression Inventory-13 (BDI-13) was used to determine depression in 766 individuals. a full report of socioeconomic factors was gathered. Lifestyle and physical activity were assessed using Health Survey Questionnaire 36-Item Short-Form and International Physical Activity Questionnaire, respectively. The dietary nutrient intake was recorded using an adjusted dietary recall.Result: A total of 58% of the population had mild to severe depression. The differences between depression groups for age, gender, SF-36 quality of life scores, and nearly all the social-economic factors were significant. females (OR=2.229 (95%CI:1.641-3.026), p<0.005) and higher age was associated with depression (OR=1.073 (95%CI:1.049-1.097), p<0.005). The impact of age, physical activity, having sport, economic level and smoking on depression were independent of all other factors. most nutrients and energy inversely associated with depression (protein (p=0.043), fiber (p=0.037), iron (p=0.041), vitamin B6 (p=0.011) and caffeine (p=0.009) was independent from the energy intake). The predictor decision tree model for depression according social-economic factors is also illustrated.Conclusion: Depression can be prevalent in a nearly healthy population. Many factors can increase the risk of depression. Currently working in males and having sport, economical level, and living with someone in females were the main depression predictors. The impact of protein, fiber, iron, vitamin B6, and caffeine on depression was independent of energy intake.
