Energy-saving optimization of the parallel chillers system based on a multi-strategy improved sparrow search algorithm

The energy usage of parallel chillers systems accounts for 25–40 % of the total energy cost of a building. In light of global warming concerns and the need for energy conservation, it is essential to distribute the load of the parallel chillers systems effectively to achieve energy savings in buildings. Accordingly, this study presents a multi-strategy improved sparrow search algorithm (MSSA) to a

Periodontitis is associated with airflow obstruction in the Malmö Offspring Dental Study

AIM: To investigate the association between periodontitis and lung function in the Malmö Offspring Dental Study.MATERIALS AND METHODS: In all 1001 individuals (49.9% female, mean age: 44.6) from Malmö Offspring Dental Study were included. Periodontitis was assessed by a full-mouth examination protocol including bleeding on probing and classified according to the American Academy of Periodontology/

How Ethnic Discrimination Shapes Political Reintegration After War : Insights from a Conjoint Experiment in Colombia

The reintegration of former armed group affiliates into formal politics is a fundamental challenge for post-conflict societies. Arguably, this challenge is even more difficult in settings where ethnic discrimination is pervasive, since discrimination implies comparatively higher barriers to political reintegration for racialized ex-combatants. In this paper, we explore how ethnicity and armed grou

New Archaeointensity Results from the Iron Age in Southern Africa

Abstract In this study we present new palaeointensity measurements on Iron Age (200 AD – 1840 AD) pottery from the southern Africa region, where there is only limited data available at present. Many sites only produce a single accepted palaeointensity result and we have therefore opted to focus on analysis at sample level as opposed to site level, which is more common in traditional archaeomagneti

Proving gender and sexuality in the (homo)nationalist Greek asylum system : Credibility, sexual citizenship and the ‘bogus’ sexual other

The aim of this article is to analyse and critique Greek authorities’ expectations for a ‘credible’ account in queer asylum claims. As some of the caseworkers’ accounts portray, through 16 semi-structured interviews, in order to be deemed ‘credibly queer’ applicants are expected to have passed through a painful, discursively narratable process of self-realization and have suffered enough in their

The Metal-weak Milky Way Stellar Disk Hidden in the Gaia–Sausage–Enceladus Debris : The APOGEE DR17 View

We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances indicative of an accreted origin and find stars with both halo-like and disk-like kinematics. The stars with halo-like kinematics lie along a lower sequenc

Ceramic Production Technology and Society : postcolonial approaches to material culture studies in southern Africa - some unanswered questions

AbstractRecently we have called for the broadening of the theoretical base in order to understand the social and other contexts of material culture items such as pottery (Pikirayi and Lindahl, 2013). The challenges encountered by archaeologists remain the huge ceramic assemblages, which are however, central in defining group identities in southern African Iron Age studies. but whose analyses Is alRecently we have called for the broadening of the theoretical base in order to understand the social and other contexts of material culture items such as pottery (Pikirayi and Llndahl, 2013).

This article reviews some of the communicative strategies of plant-based meat, a food innovation that promises an experience akin to that of animal meat, but devoid from its harmful consequences relating to the well-being of humans, animals, and the planet. Mobilizing a constitutive approach on communication, we trace the founding narrative of the Beyond Meat firm using various documents, which en

How bird feeders help small species fight infection

Every day, throughout the world, people put huge quantities of food out at feeding stations for birds and other wild animals.Although we know that connecting with nature benefits human health and wellbeing, scientists still know relatively little about the consequences of providing food for wildlife. My team’s most recent research, however, has found that feeding garden birds in wintertime seems t

Attitudes, Barriers, and Concerns Regarding Telemedicine Among Swedish Primary Care Physicians : A Qualitative Study

PURPOSE: The primary care physician's traditional patient contacts are challenged by the rapidly accelerating digital transformation. In a quantitative survey analysis based on the theory of planned behavior, we found high behavioral intention to use telemedicine among Swedish primary care physicians, but low reported use. The aim of this study was to further examine the physicians' experiences re

Institutional Complexity and Political Agency in Polycentric Governance

This chapter addresses the ways in which the complexity of global governance enables or constrains political agency. An increasingly complex global institutional system—with its growing level of unpredictability and uncertainties—challenges some of the classical institutionalist tenets in respect of conditions of power and agency. For instance, the capacities of central governance institutions and

Reducing the Impact of Bias in Oral Assessments

Oral assessment is an important method to evaluate the learning outcomes of scientific courses. However,there are certain limitations when oral assessment is applied.One of these limitations, which is not apparent in anonymous written exams, is the existence of biases which could lead to unfair (positive or negative) outcomes of the assessment. This could lead to decreased motivation and sense of

The ability to maintain rhythm is predictive of ADHD diagnosis and profile

Attention deficit hyperactivity disorder (ADHD) is the most prevalent neuropsychiatric disorder in the world. Currently, the diagnosis is based mainly on interviews, resulting in uncertainties in the clinical assessment. While some neuropsychological tests are used, their specificity and selectivity are low, and more reliable biomarkers are desirable. Previous research indicates that ADHD is assoc

Modeling China's terrestrial ecosystem gross primary productivity with BEPS model : Parameter sensitivity analysis and model calibration

Terrestrial ecosystems are the largest sink for carbon, and their ecosystem gross primary productivity (GPP) regulates variations in atmospheric carbon dioxide (CO2) concentrations. Current process-based ecosystem models used for estimating GPP are subject to large uncertainties due to poorly constrained parameter values. In this study, we implemented a global sensitivity analysis (GSA) on paramet
