The Meteorological Observations of Jean-François Gaultier, Quebec, Canada: 1742–56

Abstract Jean-Francois Gaultier was a physician in the French colony of Quebec in New France from 1742 to 1756. During that period, he recorded daily readings of temperature and observations of the weather, although only the observations for 1742–46, 1747–48, and 1754 have been located to date. Daily instrumental temperature data from Quebec for the 1740s provide a glimpse of climate variability in eastern North America, upstream of the North Atlantic. During the 1740s, winters appear to have been milder than during most of the twentieth century with the exception of the 1950s and early 1980s, and summers warmer than those of the twentieth century, with the exception of the 1970s and 1990s. Autumns and springs appear to have been cool relative to the twentieth century, suggesting that, while winters may have been milder, the winter season lasted longer, with a consequently shorter growing season. The cool springs and autumns, combined with warm winters and summers, give these few years in the 1740s annual.
Electrochemical Sensing Performances of Screen-Printed Graphene-Carbon-Paste Electrodes on Digital Microfluidic Chips

In this research, screen-printed graphene electrodes (SPGEs) were fabricated on a single-plate electrowetting-on-dielectric (EWOD) digital microfluidic chip. The chip contained T-junction EWOD structures for merging buffer reagent and analyzed droplets and the electrochemical sensor based on SPGEs at the end of T-junction. The EWOD structures consisted of silver EWOD electrodes, a polydimethylsiloxane dielectric layer, and Teflon1AF hydrophobic layers. The electrochemical sensor comprised a working SPGE, a counter SPGE, and a screen-printed silver/silver chloride reference electrode. Both EWOD and electrochemical electrodes were fabricated by a screen-printing technique. The digital microfluidic chip with the SPGE sensor was applied to mix and analyze three biochemical reagents, including potassium hexacyanoferrate (<inline-formula> <tex-math notation="LaTeX">$\text{K}_{{4}}$ </tex-math></inline-formula>Fe(CN)<inline-formula> <tex-math notation="LaTeX">$_{{6}}{)}$ </tex-math></inline-formula>, nicotinamide adenine dinucleotide (NADH), and hydrogen peroxide (<inline-formula> <tex-math notation="LaTeX">$\text{H}_{{2}}\text{O}_{{2}}{)}$ </tex-math></inline-formula>. The electrochemical measurements were conducted using cyclic voltammetry over the concentration ranges of <inline-formula> <tex-math notation="LaTeX">$10-500\,\,\mu \text{M}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$10-500\,\,\mu \text{M}$ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$1000-7500\,\,\mu \text{M}$ </tex-math></inline-formula> for <inline-formula> <tex-math notation="LaTeX">$\text{K}_{{4}}$ </tex-math></inline-formula>Fe(CN)6, NADH, and <inline-formula> <tex-math notation="LaTeX">$\text{H}_{{2}}\text{O}_{{2}}$ </tex-math></inline-formula>, respectively. The results showed that the detection performances, including sensitivity and detection limit of SPGE sensor on the EWOD chip, were considerably better than those of screen-printed carbon paste electrodes (SCPEs).
Errors in Areal Weighting Interpolation between Incompatible Zonal Systems

Map overlay operation in GIS is often followed by a data transfer between incompatible zonal systems. There are various methods of data transfer which are called areal interpolation methods. Any interpolation methods, however, involve error in data transfer because of insufficient information about the distribution of spatial objects in overlaid zones. This paper proposes a probabilistic model of the error in count data transferred through the areal weighting method, and analyze the relationship among the source zonal system, target zone, and the distribution of spatial objects whose counts are recorded in GIS. Both theoretical and empirical findings are shows.
Social exclusion as a barrier to poverty reduction : the case of Basarwa in Botswana.

In most developing countries the characteristics ofthe poor go beyond the traditional definition ofpoverty. Whilst the latter broadly refers to lack of access to material resources, there are other factors that are linked to poverty. This thesis identifies one of these factors as soCial exclusion which is suggested as a barrier to poverty reduction efforts. Drawing from the experience on the concept of social exclusion as developed in the north, and extended to some countries in the south, the social exclusion framework is applied within the context of a country in the south, namely Botswana. The thesis investigates the operation of social exclusion within the Basarwa minority group in the country, by identifying the appropriate mechanisms that drive social exclusion, describing the processes of exclusion, and delineating its characteristics. This is done within the context of testing the proposition that social exclusion is one of the factors linked to the persistence of poverty. Noting that persistence of poverty is conventionally attributed, among others things, to shortfall in education and skills, lack of opportunities and capital or land, the thesis investigates the root causes of these factors in as far as Basarwa are concerned. It is argued that such shortfalls and failure to obtain adequate resources are due to exclusionary processes operating at two levels. The major findings are that the concept is multidimensional and that the target group faces exclusion in political, socio-cultural, economic, spatial and legal terms. This exclusion operates at the national and local levels. Owing to this multiple exclusion, Basarwa generally face difficulties in escaping poverty, with the older generation being the most affected. Social exclusion is a barrier to poverty reduction because it makes it difficult for the Basarwa to obtain equal and satisfactory access to opportunities, assets, and resources available in political, economic and social fields of society. The thesis offers some policy suggestions about how to reduce social exclusion.
Analyzing Seismicity Pattern of the Gorontalo Region and Its Surroundings in the Form of Hypocenter Relocation Using Double Difference Method

The level of seismic activity due to earthquake events in Gorontalo is strongly influenced by the tectonic system model of the Gorontalo region and the presence of a subduction zone in the Sulawesi Sea. These characteristics make the Gorontalo region have high seismic activity. To describe the pattern of seismicity in the Gorontalo region, it is necessary to conduct an analysis in the form of earthquake hypocenter relocation using the double difference (hypoDD) method. This method uses residual travel time data from each pair of hypocenters to the recording station. This study aims to analyze the results of hypocenter relocation and describe the subsurface model related to the seismicity pattern of Gorontalo and its surroundings. The data used are P and S waves for 7 years recorded at the Meteorology, Climatology and Geophysics Agency (BMKG) station. The earthquake hypocenters relocated in this study were 3,940 out of 4,598 earthquake events. The results of hypocenter relocation show a fairly good seismicity pattern obtained from good RMS values and distribution patterns following Gorontalo tectonic patterns. In general, the seismicity pattern of Gorontalo and its surroundings is strongly influenced by activity in the Sulawesi Sea subduction zone and the Gorontalo fault in the region. The seismicity caused by the subduction zone has a depth of 50 - 200 km, and due to the active faults in the Gorontalo region has a depth of 2 - 25 km.
Self-sensing ultra-high performance concrete: a review

Ultra-high performance concrete (UHPC) is an innovative cementitious composite, that has been widely applied in numerous structural projects because of its superior mechanical properties and durability. However, ensuring the safety of UHPC structures necessitates an urgent need for technology to continuously monitor and evaluate their condition during their extended periods of service. Self-sensing UHPC (SSUHPC) extends the functionality of UHPC system by integrating conductive fillers into the UHPC matrix, allowing it to address above demands with great potential and superiority. By measuring and analyzing the relationship between fraction change in resistivity and external stimulates (force, stress, strain), SSUHPC can effectively monitor the crack initiation and propagation as well as damage events in UHPC structures, thus offering a promising pathway for structural health monitoring (SHM). Research on SSUHPC has attracted substantial interests from both academic and engineering practitioners in recent years, this paper aims to provide a comprehensive review on the state of the art of SSUHPC. It offers a detailed overview of material composition, mechanical properties and self-sensing capabilities, and the underlying mechanisms involved of SSUHPC with various functional fillers. Furthermore, based on the recent advancements in SSUHPC technology, the paper concludes that SSUHPC has superior self-sensing performance under tensile load but poor self-sensing performance under compressive load. The mechanical and self-sensing properties of UHPC are substantially dependent on the type and dosage of functional fillers. In addition, the practical engineering SHM application of SSUHPC, particularly in the context of large-scale structure, is met with certain challenges, such as environment effects on the response of SSUHPC. Therefore, it still requires further extensive investigation and empirical validation to bridge the gap between laboratory research and real engineering application of SSUHPC.
Evaluación físico-química y microbiológica de la calidad del agua de los ríos Machángara y Monjas de la red hídrica del distrito metropolitano de Quito (DMQ).

This study analyses the current condition of Machangara and Monjas rivers, by evaluating the quality of its waters. These rivers are an important part of the DMQ's water network and run through areas of high population density, receiving domestic and industrial discharges, daily. Physical and chemical parameters (flow, pH, temperature, dissolved oxygen and ORP) were evaluated by in situ monitoring, during the months of August, September, October and November 2014. Water samples were also taken for microbiological analysis (total coliforms TC and fecal coliforms FC) in laboratory, using the Multiple Tube Fermentation method, established by the Standard Methods. The analyzes show that both rivers far exceed the permissible limits established in TULSMA for total coliforms, fecal coliforms, temperature, and dissolved oxygen in the case of Monjas River. This prevents their use for wildlife preservation, and agricultural and livestock activities. A considerable increase in the flow of both rivers was also reflected on the results; in addition, the ORP value is in both, less than the 650mV optimum value. The results obtained confirm the poor water quality of the studied rivers, which is why a recovery project based on a SSF wetland system, is proposed, showing possible construction sites and the advantages this system has (environmentally friendly, affordable and with significant community benefits) compared with conventional treatment systems.
Genetic characterization of Iranian subpopulations using 15 forensic autosomal STR loci

The objective of present study was to compare genetic structure of seven Iranian provinces and to understand the genetic relationship among these seven provinces (Isfahan, Fars, Hormozgan, Kerman, Chaharmahal & Bakhtiari, Kohgiluyeh & Boyer Ahmad, and Yazd). For this purpose, a set of 15 STR’s loci were investigated. This panel of STRs is standard forensic science genetic testing tool that we added some importance to them by putting them in genetic variation analysis. The results based upon Fisher exact test for Hardy-Weinberg equilibrium (HWE) indicated that the allele and genotype distributions were in accordance with Hardy-Weinberg expectations except for D16S539. From genetic diversity point of view, D2S1338 was among the best STR loci and Isfahan has the highest value in aspect of these indices. Our results indicated that high amount of gene flow have been from Isfahan to Fars, which should be further investigated. Also, we indirectly shown that those forensic motivated genetic markers could be used as reliable tool for genetic differentiation when sounds data are available. We did not mean to estimate forensic science specific measures e.g. probability match and etc. for current study.
Calculated X-ray diffraction curves for the interpretation of a three-component interstratified system

Abstract Three-component interstratification of layer silicate minerals in the clay fractions of soils and sediments is probably more common than is generally realized. However, interpretation of the proportion and arrangement of the various components from experimentally recorded X-ray diffraction curves is difficult and in this paper a series of calculated diffraction patterns are presented which illustrate the types of diffraction patterns obtained from interstratified mica-vermiculite-montmorillonite systems.
C OLLABORATIVE F EEDBACK A PPROACH FOR I MPROVING C USTOMER E NGAGEMENT AND P RODUCT I NCREMENT IN A GILE S OFTWARE D EVELOPMENT

— Customer engagement and feedback are crucial in agile software development to ensure the product released meets their needs. However, lack of involvement and delayed feedback are the main challenges, especially if the customers are in distributed locations. These could cause the product increment quality, poor iteration planning decisions, and late product delivery. A collaborative feedback approach is proposed in this paper to support gathering feedbacks of product increment and decision-making in iteration development planning. The proposed approach also embraces a quality assurance (QA) mechanism to ensure quality adheres to the product increment. An evaluation was conducted where a tool, called CrowFeID, was developed as a proof-of-concept of the proposed approach and to support the iteration review process. As a conclusion from the responses received, the proposed approach and tool can reduce delayed feedback during the iteration review and provides valuable input in making decisions for the product increment and next iteration planning.

An online and automated measurement approach based on LiDAR point cloud data for luggage dimensions is proposed, in order to enhance real-time precision and accuracy in luggage dimension measurements. This method is applicable to stationary luggage at airports and stations. Firstly, luggage point clouds are rapidly extracted based on scene information. Secondly, luggage types are determined based on luggage characteristics, which include regular and irregular luggage. Finally, luggage dimensions are computed to obtain the length, width, and height of the luggage. The experiment demonstrates that this method can achieve efficient measurement of luggage dimensions for various shapes, which presents certain practical value.
No Changes in the Occurrence of Methicillin-Resistant Staphylococcus aureus (MRSA) in South-East Austria during the COVID-19 Pandemic

Methicillin-resistant Staphylococcus aureus (MRSA) is a universal threat. Once being well established in the healthcare setting, MRSA has undergone various epidemiological changes. This includes the emergence of more aggressive community-acquired MRSA (CA-MRSA) and the occurrence of MRSA which have their origin in animal breeding, called livestock-associated MRSA (LA-MRSA). Emergence of new clones as well as changes in the occurrence of some clonal lineages also describes the fluctuating dynamic within the MRSA family. There is paucity of data describing the possible impact of the COVID-19 pandemic on the MRSA dynamics. The aim of the study was the analysis of MRSA isolates in a three-year time period, including the pre-COVID-19 years 2018 and 2019 and the first year of the pandemic 2020. The analysis includes prevalence determination, antibiotic susceptibility testing, spa typing, and detection of genes encoding the PVL toxin. The MRSA rate remained constant throughout the study period. In terms of a dynamic within the MRSA family, only a few significant changes could be observed, but all except one occurred before the start of the COVID-19 pandemic. In summary, there was no significant impact of the COVID-19 pandemic on MRSA in Austria.
Topical and field‐tested residual effects of globally used insecticides on the parasitoid Tamarixia radiata released against the Asian citrus psyllid, Diaphorina citri

Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) is the key parasitoid of the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Liviidae), in several citrus‐producing regions of the world. Chemical control is common to suppress ACP. Insecticides from globally used classes of insecticides for controlling ACP were tested on its primary parasitoid, T. radiata. Evaluations included dose–response of dimethoate, fenpropathrin, and imidacloprid in a topical application and lethal and sublethal effects from residues of imidacloprid, fenpropathrin, horticultural mineral oil (HMO), pyrethrin, and spirotetramat at 1, 3, and 7 days after application (DAA) of sprays on citrus trees in the orchard. The parasitism potential of the females that survived insecticide exposure was evaluated on untreated nymphs of ACP developing on citrus shoots and untreated parasitoid females were evaluated on nymphs treated with insecticides. In the topical application, imidacloprid was 8× more toxic to T. radiata than dimethoate and fenpropathrin. The lethal effect of the residues from imidacloprid and fenpropathrin sprays was more detrimental than other insecticides. Parasitoid mortality from 1‐ to 3‐day‐old residues averaged 90–96% for imidacloprid, 83–94% for fenpropathrin, 38–77% for pyrethrin, 43–44% for HMO, and 17–33% for spirotetramat. Parasitism by females that survived insecticide exposure was reduced by 71–88% from fenpropathrin, 28–59% from pyrethrin, 31–55% from imidacloprid, 44–4% from spirotetramat, and 39–11% from HMO compared to untreated females. The lethal and sublethal effects of all insecticides on T. radiata were significantly reduced at 7 DAA, suggesting a lower impact on its establishment and performance if releases are made after a week from spray application.
The complexity of leadership competence in universities in the 21st century

Abstract In 21st-century higher education, effective managerial skills are crucial for quality assessment. ABC University aims to be an Excellent University by 2047, but leadership competence remains a barrier to this goal. This study focuses on the managerial abilities of the rector and vice-rector in managing higher education operations. The Research paradigm used is constructivist paradigm utilizing qualitative research methods. The study adopts a case study approach, investigating a specific context where the phenomenon of interest is occurring and holds significance for examination. The research commenced by gathering secondary data through preliminary key informant interviews, engaging with 12 former deans and vice deans. The researcher determined the focus and sub-focus of the research followed by collecting observation data and semi-structured interviews with informants consisting of 7 deans, 6 vice deans, 2 heads of departments, and 2 heads of institutions. The sampling method used was purposive and snowball sampling. The data undergoes analysis via the Manual Data Analysis Procedure, employing a thematic inductive approach to generate memos and ultimately construct a conceptual framework of managerial competency. The study reveals that the competency standards for rectorate leaders during the period 2020–2022 are inadequate, encompassing areas such as adaptive leadership, comprehensive managerial proficiency, and intelligent collegial relationships. This lack of effective communication and collaboration has an impact on the process of propelling ABC University towards excellence.

This encompasses examinations, summaries, comparative assessments, and the constraints of existing studies. We conclude by delineating future research directions in this crucial field.
Information Visualisation Tools to Explore Fra Mauro’s World Map (dated 1460 CE)

Summary: Historical maps are a traditional source for historical research. Their significance as historical and cultural artefacts have increased in the digital space. However, the user experience does not take full advantage of what the digital space can offer. This research shares how the international initiative Engineering Historical Memory (EHM) designed and developed online tools to facilitate an engaging and practical user experience at different education levels. EHM used Fra Mauro’s world map (dated 1460) to showcase information visualisation solutions to enhance the user interaction with the historical information embedded in historical cartography.
