Optimum Distribution System Expansion Planning Incorporating DG Based on N-1 Criterion for Sustainable System

Demand for continuous and reliable power supply has significantly increased, especially in this Industrial Revolution 4.0 era. In this regard, adequate planning of electrical power systems considering persistent load growth, increased integration of distributed generators (DGs), optimal system operation during N-1 contingencies, and compliance to the existing system constraints are paramount. However, these issues need to be parallelly addressed for optimum distribution system planning. Consequently, the planning optimization problem would become more complex due to the various technical and operational constraints as well as the enormous search space. To address these considerations, this paper proposes a strategy to obtain one optimal solution for the distribution system expansion planning by considering N-1 system contingencies for all branches and DG optimal sizing and placement as well as fluctuations in the load profiles. In this work, a hybrid firefly algorithm and particle swarm optimization (FA-PSO) was proposed to determine the optimal solution for the expansion planning problem. The validity of the proposed method was tested on IEEE 33- and 69-bus systems. The results show that incorporating DGs with optimal sizing and location minimizes the investment and power loss cost for the 33-bus system by 42.18% and 14.63%, respectively, and for the 69-system by 31.53% and 12%, respectively. In addition, comparative studies were done with a different model from the literature to verify the robustness of the proposed method.
Empirical Insights Into the Fate of Ammonia in Western U.S. Wildfire Smoke Plumes

Wildfires are a major source of gas‐phase ammonia (NH3) to the atmosphere. Quantifying the evolution and fate of this NH3 is important to understanding the formation of secondary aerosol in smoke and its accompanying effects on radiative balance and nitrogen deposition. Here, we use data from the Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE‐CAN) to add new empirical constraints on the e‐folding loss timescale of NH3 and its relationship with particulate ammonium (pNH4) within wildfire smoke plumes in the western U.S. during summer 2018. We show that the e‐folding loss timescale of NH3 with respect to particle‐phase partitioning ranges from ∼24 to ∼4000 min (median of 55 min). Within these same plumes, oxidation of nitrogen oxides is observed concurrent with increases in the fraction of pNH4 in each plume sampled, suggesting that formation of ammonium nitrate (NH4NO3) is likely. We find wide variability in how close our in situ measurements of NH4NO3 are to those expected in a dry thermodynamic equilibrium, and find that NH4NO3 is most likely to form in fresh, dense smoke plumes injected at higher altitudes and colder temperatures. In chemically older smoke we observe correlations between both the fraction of pNH4 and the fraction of particulate nitrate (pNO3) in the aerosol with temperature, providing additional evidence of the presence of NH4NO3 and the influence of injection height on gas‐particle partitioning of NH3.
Subsurface oceanic structure associated with atmospheric convectively coupled equatorial Kelvin waves in the eastern Indian Ocean

<p>Atmospheric convectively coupled equatorial Kelvin waves (CCKWs) are a major tropical weather feature strongly influenced by ocean--atmosphere interactions. However, prediction of the development and propagation of CCKWs remains a challenge for models. The physical processes involved in these interactions are assessed by investigating the oceanic response to the passage of CCKWs across the eastern Indian Ocean and MC using the NEMO ocean model analysis with data assimilation. Three-dimensional life cycles are constructed for "solitary" CCKW events. As a CCKW propagates over the eastern Indian Ocean, the immediate thermodynamic ocean response includes cooling of the ocean surface and subsurface, deepening of the mixed layer depth, and an increase in the mixed layer heat content. Additionally, a dynamical downwelling signal is observed two days after the peak in the CCKW westerly wind burst, which propagates eastward along the Equator and then follows the Sumatra and Java coasts, consistent with a downwelling oceanic Kelvin wave with an average phase speed of 2.3 m s<sup>-1</sup>. Meridional and vertical structures of zonal velocity anomalies are consistent with this framework. This dynamical feature is consistent across distinct CCKW populations, indicating the importance of CCKWs as a source of oceanic Kelvin waves in the eastern Indian Ocean. The subsurface dynamical response to the CCKWs is identifiable up to 11 days after the forcing. These ocean feedbacks on time scales longer than the CCKW life cycle help elucidate how locally driven processes can rectify onto longer time-scale processes in the coupled ocean--atmosphere system. </p>

Common Limitations and Challenges of Dietary Clinical Trials for Translation into Clinical Practices

The progressive development of clinical and public health nutrition has long relied on dietary clinical trials (DCTs), investigating the causal relationship between diet and multiple risk factors of non-communicable and chronic diseases. DCTs are also hallmarks for establishing dietary requirements and promoting overall nutritional health among the population. Despite their critical importance in translation into public health strategies and practices, DCTs have several limitations and challenges for study design, implementation and finding interpretation. The complex nature of nutrition interventions, collinearity between diet components, multi-target effects of the interventions, diverse dietary behaviors, and food culture are the most challenging issues. Furthermore, baseline exposure and dietary status, appropriate control groups, blinding, randomization, and poor adherence undermine the effectiveness of DCTs in translation into practices. Disruptive factors will be minimized if researchers are committed to following good clinical practice (GCP) standards available for common designs of clinical trials. Planning DCTs, however, needs careful considerations for hypothesis generation, study design development, the definition of primary and secondary outcome measures, and target population.
Does assortative mating contribute to reproductive isolation among sympatric ecotypes of the wing‐dimorphic stonefly Zelandoperla fenestrata (Plecoptera: Gripopterygidae)?

Testing for reproductive isolation among sympatrically diverging lineages is a key prerequisite for understanding speciation processes. Recent genome‐wide studies of the wing‐dimorphic New Zealand stonefly Zelandoperla fenestrata have revealed evidence for ecological speciation among sympatric ecotype pairs, but the basis for their apparent reproductive isolation remains unclear. We conduct paired mating tests among co‐distributed Z. fenestrata ecotypes from southern South Island to test for prezygotic barriers contributing to their reproductive isolation and divergence. Experimental data reveal assortative mating among ecotypes, with strong differentiation in the duration of matings between matched‐ecotype pairs relative to non‐matched pairs. These findings add weight to the hypothesis that assortative mating can be a key mechanism facilitating rapid ecological speciation of sympatric ecotypes. Our study also represents the first documentation of mating behaviours in the Southern Hemisphere stonefly suborder Antarctoperlaria.
Which Review Can Make You Engage?: The Effect of Reviewer-Reader Similarity on Consumer-Brand Engagement

Online reviews facilitate customer-brand engagement, but few studies have explored this problem from the perspective of interpersonal attraction and its psychological mechanisms in the social commerce context. This paper aims to investigate the effect of reviewer-reader similarity (including external and internal similarity) in online reviews on customer-brand engagement in the social commerce context. Drawing upon the social categorization theory, a conceptual framework was developed and tested empirically. Data collected from a sample of Chinese consumers with the shopping experience on social commerce websites (N=392) was analyzed using partial least square (PLS). Findings reveal that both external and internal similarities are indirectly influenced consumer-brand engagement and mediated by consumers’ perceived value and congruence transferred through this process. The impact of external similarity on customer-brand engagement was greater through consumers’ perceived value, whereas the influence of internal similarity was stronger through consumers’ self-brand congruence.
High Efficiency Si/CdS Radial Nanowire Heterojunction Photodetectors Using Etched Si Nanowire Templates

p-Si/n-CdS radial heterojunction nanowires have been grown by pulse laser deposition of CdS on vertically aligned Si nanowires fabricated using a room temperature wafer-scale etching of p-type Si. Temperature-dependent photoluminescence characteristics have been studied in detail in the blue–green–red regions from these p-Si/n-CdS core–shell nanowires. The photocurrent spectra of the nanowire heterojunctions have been investigated at room temperature to study the spectral responsivity and detectivity of the core–shell nanowire diodes. The peak responsivity (1.37 A/W) and detectivity (4.39 × 1011 cm Hz1/2/W) at −1 V show the potential of the nanoscaled devices for the high efficiency photodetectors in the visible–near-infrared spectrum.
Pathways for sexual health promotion among Indigenous boys and men: stakeholder perspectives

The sexual health of Indigenous Peoples in Canada has been identified as an important community and public health concern; however, there is a lack of research on the sexual health needs of Indigenous boys and men. This article shares results from interviews conducted with six stakeholders to explore pathways for sexual health promotion and considers the impacts of colonialism and other socio-political contextual factors on Indigenous boys’ and men’s sexual health. The study employed thematic analysis, and the findings indicate the following three pathways for sexual health promotion of Indigenous boys and men: (1) developing healthy relationships and highlighting role models, (2) providing access to comprehensive sexual health information, and (3) fostering open communication among Indigenous boys and men. Sexual health promotion with Indigenous boys and men in Atlantic Canada should include addressing the impacts of colonization and their unique socio-cultural contexts.
¡Venceremos!: Challenging School Barriers with Latinx Youth Participatory Action Research

ABSTRACT The purpose of this paper is to utilize systematic review methodology to describe how Latinx youth engage in youth participatory action research (YPAR) in the secondary school context. Of the 961 articles in the database search, 13 studies were included in the final sample. I analyzed the studies thematically and coded for YPAR characteristics and principles. I analyzed the literature review corpus deductively according to Rodríguez and Brown's three guiding principles of participatory action research: situated and inquiry-based, participatory, and transformative and activist. All studies demonstrated various ways the principles apply to YPAR with Latinx youth. In conclusion, this systematic review describes the knowledge and skills Latinx students develop through PAR. This paper offers recommendations on how future research can empower Latinx communities to address and overcome obstacles in education.
A Thermal Grooving Study of Relative Grain Boundary Energies of Nickel in Polycrystalline Ni and in a Ni/YSZ Anode Measured by Atomic Force Microscopy

Abstract Grain boundary grooves of nickel were studied in Ni polycrystals and in Ni/YSZ (nickel/yttria-stabilized zirconia) anode microstructures of an solid oxide fuel cell (SOFC) in order to determine the relative grain boundary energies of nickel. Reliable material parameters are necessary for realistic simulations to model the coarsening of nickel grains in SOFC anodes. However, the reported values in literature do not meet the requirements for accuracy and the experimental conditions differ strongly from the conditions within an anode. In this work, the measurement approach for atomic force microscopy was optimized to ensure the required accuracy in measuring grain boundary grooves; the thermal grooving experiments were performed at T = 750 ∘ C in dry and humid atmosphere. The resulting distributions of measured dihedral angles and relative grain boundary energies are identical in the polycrystal and the anode microstructure and are independent of annealing time and humidity. For the first time, precise values of the relative grain boundary energies of nickel are determined with high accuracy under operating conditions of an SOFC anode. The mean value of the relative grain boundary energies γ GB / γ S of nickel is 0.475 ± 0.013 for high-angle grain boundaries, 0.217 ± 0.010 for low-angle grain boundaries, 0.157 ± 0.013 for Σ 3 grain boundaries and 0.019 ± 0.002 for twin boundaries.
Chain Transfer Kinetics of Acid/Base Switchable N-Aryl-N-Pyridyl Dithiocarbamate RAFT Agents in Methyl Acrylate, N-Vinylcarbazole and Vinyl Acetate Polymerization

The structures of the “Z” and “R” substituents of a RAFT agent (Z–C(S)S–R) determine a RAFT agent’s ability to control radical polymerization. In this paper we report new acid/base switchable N-aryl-N-pyridyl dithiocarbamates (R = −CH2CN, Z = −N(Py)(Ar)) which vary in substituent at the 4-position of the aryl ring and the use of these to control molecular weight and dispersity. In their protonated form, the new RAFT agents are more effective in controlling polymerization of the more activated monomer, methyl acrylate (MA), whereas in their neutral form they provide more effective control of the polymerization of less activated monomers, N-vinyl carbazole (NVC) and vinyl acetate (VAc). For each polymerization, the apparent chain transfer coefficient (Ctrapp) shows a good correlation with Hammett parameters. Dithiocarbamates with more electron-withdrawing aryl ring substituents have the higher Ctrapp. This demonstrates the influence of polar effects on Ctrapp and supports the hypothesis that the activity of.
Downward Interest Rate Rigidity

Empirical evidence suggests that bank lending rates are downward rigid: banks tend to adjust their rates more slowly and less completely to short-term market rates decreases than to increases. We investigate the macroeconomic consequences of this downward interest rate rigidity by introducing asymmetric bank lending rate adjustment costs in a macrofinance dynamic stochastic general equilibrium model. Calibrating the model to the euro area economy, we find that the difference in the initial response of GDP to positive and negative economic shocks of similar amplitude can reach up to 25%. This means that a central bank would have to cut its policy rate much more to obtain a symmetric medium-run impact on GDP. We also show that downward interest rate rigidity is stronger when policy rates are stuck at their effective lower bound, further disrupting monetary policy transmission. These findings imply that neglecting asymmetry in retail interest rate adjustments may yield misguided monetary policy decisions.
Sonotrodes for Ultrasonic Welding of Titanium/CFRP-Joints—Materials Selection and Design

Ultrasonic welding of titanium alloy Ti6Al4V to carbon fibre reinforced polymer (CFRP) at 20 kHz frequency requires suitable welding tools, so called sonotrodes. The basic function of ultrasonic welding sonotrodes is to oscillate with displacement amplitudes typically up to 50 µm at frequencies close to the eigenfrequency of the oscillation unit. Material properties, the geometry of the sonotrode, and the sonotrode tip topography together determine the longevity of the sonotrode. Durable sonotrodes for ultrasonic welding of high-strength joining partners, e.g., titanium alloys, have not been investigated so far. In this paper, finite element simulations were used to establish a suitable design assuring the oscillation of a longitudinal eigenmode at the operation frequency of the welding machine and to calculate local mechanical stresses. The primary aim of this work is to design a sonotrode that can be used to join high-strength materials such as Ti6Al4V by ultrasonic welding considering the longevity of the welding tools and high-strength joints. Material, sonotrode geometry, and sonotrode tip topography were designed and investigated experimentally to identify the most promising sonotrode design for continuous ultrasonic welding of Ti6AlV4 and CFRP. Eigenfrequency and modal shape were measured in order to examine the reliability of the calculations and to compare the performance of all investigated sonotrodes.
Structure in Distance Learning: A Systematic Literature Review

The research aims to determine the elements under the structural component in distance learning environments. The research was conducted as a systematic literature review. The research was conducted on a total of 54 studies. The studies were accessed through the electronic databases accessible at Gazi University. A PRISMA flow chart was used to select the studies. The classification of the studies into categories and codes was done using content analysis, in terms of the structural component. A total of 78 codes were found in 5 categories under which 5409 codings were made. It was found that under the structural component, the Technology category was the most frequently used. This category is followed by flexibility-rigidity, assessment, guidance and curriculum. The most frequently used code in the studies is individual feedback, which falls under the flexibility-rigidity category. As a result of the study, some suggestions were made for designers of distance education media. They should pay maximum attention to the flexibility-rigidity category to support students’ sense of belonging. It is recommended to use different (textual, audio/video) feedback methods in the learning environment. They are expected to pay more attention to the Curriculum category to support learner success. The roles of teachers and learners should be clearly defined. Technology should be planned to support all processes such as interaction, access to content, communication, sharing, collaboration, and evaluation that may be experienced in the learning environment. Formative evaluation should be considered important and more than one method of performance assessment should be used. Since technological platforms are the basic elements of communication, they should be used extensively in learning environments.
Weed Management through Imidazolinones in Pigeon Pea (Cajanus cajan L.)

Background: Pulse crops are commonly known as poor man’s meat. Pigeon pea is second most important pulse crops of India after chickpea. Weeds are amongst prime biotic factors limiting pigeon pea yield and can cause seed yield losses up to 80 per cent. Promising result of weed control by pendimethalin was documented in pigeon pea. Also Imazethapyr is applied as pre and post emergence to control grasses and broad leaved weeds in other pulse crops but limited research was undertaken in pigeon pea. Therefore, current experiment focused to compare the effect of imidazolinones alone and in combination in pigeon pea. Methods: To control weeds in pigeon pea, pre and post-emergence of imidazolinones alone and in combination with pendimethalin was applied. Nutrient content, nutrient uptake, productivity and economics of pigeon pea were worked out.Conclusion: Among herbicidal treatments, the highest nutrient content, nutrient uptake, productivity, net returns and benefit cost ratio in pigeon pea were observed in the pre-emergence application of pendimethalin + imazethapyr @ 1000 + 75 g ha-1. Therefore, this treatment may be an effective and profitable alternative to the existing manual and costlier recommendation (two hoeing at 25 and 45 DAS) of weed control in pigeon pea in Haryana locality.
The Most Discouraged Mycenaeans: Performing Emotion and Death in Late Bronze Age Tanagra, Greece

ABSTRACT The paper examines the famous Tanagra terracotta coffins (larnakes) as loci of enduring memory that contributed to the construction of funerary place and sought to prescribe affect within the heterotopic spaces of tombs. Their complex materialities, which allude to different media, elite and vernacular, local and distant, as well as their evocative iconography, rendered them powerful resources by which to remember ancestors and normatively prescribed affect on the occasion of death. Based on a new synthesis, the study discusses the material and iconographic characteristics of the larnakes and their spatial contexts from the perspective of affect. The larnakes are then cast against broader affective practices, concepts, and visual traditions of the Bronze Age and the later Greek world, and a tentative affective script for death at Tanagra is proposed.
Personality coherence in acts and texts: Searching for coherence within and beyond trait categories

This paper reports two studies that explore complementary aspects of personality coherence. Study 1 addressed cross-situational coherence in contextualized psychological response. Idiographically-tailored methods assessed individuals’ (i) beliefs about their personal attributes, (ii) subjective “mappings” of these attributes to everyday circumstances, and (iii) self-reported contextualized action tendencies. A novel index of idiographic–nomothetic relations gauged the degree to which the idiographic methods yield unique information. Participants’ mappings commonly deviated from the structure of nomothetic trait categories; people often grouped together contextualized action tendencies traditionally associated with different trait categories. The idiographic mappings predicted cross-situational coherence in action tendencies. Study 2 asked whether the contextualization of personal qualities would be evident when people merely are asked to describe their personal attributes in natural language. Participants wrote narratives describing positive and negative qualities. Narratives were coded for the presence of three linguistic features: conditional statements, probabilistic statements, and personality trait inconsistencies. All three occurred frequently. Furthermore, they co-occurred; among participants who described trait-inconsistent attributes, the large majority spontaneously cited conditions in which these attributes are manifested. People who recognize that they possess inconsistent personal qualities may nonetheless attain a coherent understanding of themselves by spontaneously developing a contextually-embedded sense of self.
