Distinct mechanisms mediate X chromosome dosage compensation in Anopheles and Drosophila
Authors: Keller Valsecchi Claudia Isabelle , Marois Eric , Basilicata M Felicia , Georgiev Plamen , Akhtar Asifa
Published: July 2021

Sex chromosomes induce potentially deleterious gene expression imbalances that are frequently corrected by dosage compensation (DC). Three distinct molecular strategies to achieve DC have been previously described in nematodes, fruit flies, and mammals. Is this a consequence of distinct genomes, functional or ecological constraints, or random initial commitment to an evolutionary trajectory? Here, we study DC in the malaria mosquito Anopheles gambiae. The Anopheles and Drosophila X chromosomes evolved independently but share a high degree of homology. We find that Anopheles achieves DC by a mechanism distinct from the Drosophila MSL complex–histone H4 lysine 16 acetylation pathway. CRISPR knockout of Anopheles msl-2 leads to embryonic lethality in both sexes. Transcriptome analyses indicate that this phenotype is not a consequence of defective X chromosome DC. By immunofluorescence and ChIP, H4K16ac does not preferentially enrich on the male X. Instead, the mosquito MSL pathway regulates conserved developmental genes. We conclude that a novel mechanism confers X chromosome up-regulation in Anopheles. Our findings highlight the pluralism of gene-dosage buffering mechanisms even under similar genomic and functional constraints.

An analysis of the bone serrated points from the burial complexes of Shamanka 2 burial ground is presented. The origin of the collection makes it “ritual”, which may explain the large number of undamaged items. Several spikes have been broken intentionally at the time of their interment. Supposedly, several points have been specifically made for interment. In accordance with the morphological analysis, we have identified two groups of serrated spikes: (I) detachable tools and (II) non-detachable tools. Differences in structural elements of the stopper-line determine 7 types of harpoons (95 items), and variations in base structure define 2 types of points of leisters, javelins, spears etc. (6 items), while 15 fragments of blade were excluded from the analysis. Harpoons of the Type I-1 and Type I-2 are divided into 9 varieties, in accordance with structural elements of the blade. Harpoons of the Type I-3 are divided into 2 subtypes due to differences in structural elements of the shaft. Harpoons of the I-4 – I-7 types are represented by only 1 item for each type and are considered to be individual tools. Group I (harpoons) consist mostly of tools with an orifice for line lashing (89 items). Harpoons that feature stopper-line structural elements without through hole are represented here by only 6 items. II-2 type points with a unilaterally beveled base represent most non-detachable barbed tools – 5 items. II-1 type points with a wedgelike base (in a profile) consist of only 1 item. The designated types and varieties of Shamanka II cemetery barbed spikes correlate with items from different synchronous and asynchronous sites of both bordering and substantially remote regions. Serrated points are found mainly in male burials but absent in children's burials. Chronologically, 111 barbed spikes relate to the Phase 1 of the Shamanka 2 cemetery functioning. Five more spikes were recorded in 3 burials of the Phase 2. Barbed spikes of the chronological Phase 2 are represented with 4 items of the I-1.4 variety from burials No. 108-1 and 64-2, as well as 1 item of the I-2-1 variety from a grave No. 49. The last artifact probably represents an ideal model of two-row harpoons with symmetrically situated barbs and a sword-like spike. Harpoons with a curved blade (Type I-1.4) were registered only in burials of the chronological Phase 2. The barbed spikes of the I-1 and I-2 types, which feature a stopper-line with through holes and lateral projections, correlate with a definition of harpoons of the Kitoi type.

Published: July 2021

Archeology is the only branch of human study that relies more on material remains left by people than on direct observation of human behavior or on written evidence. This focus on material evidence compels archaeologists to improve the methods and techniques of collecting and interpreting data that ensure the extraction of maximum information from available sources. The article provides an analysis of existing national and foreign information and geoinformation systems representing data on archaeological finds, cultural sites, and research documentation. A description of the existing standards, which regulate the list of attributes of geoarchaeological objects, is provided. The article also describes the stages of conceptual and logical modeling of the “ArchaeoNomos” database, which represents a unified repository for all data accompanying archaeological investigations, archaeological research and design, and documentation of research activities of the Scientific Research Center “Baikal Region” of Irkutsk State University. The problem of automating the processes of storage, processing, modification, and interpretation of geoarchaeological data is formulated. The system analysis of the subject area, system specification of an application that works with a database, the surveying specialists of the subject area to identify associations between database objects are presented. The infological and physical models of data presentation in the database are described, which allows the integration of the accumulated archaeological data into larger scientific associations. Finally, the advantages and disadvantages of using relational databases as repositories for archaeological data are outlined. The purpose of creating the “ArchaeoNomos” database is to implement measures for the preservation of the archaeological heritage, including the introduction and the use of the database by scientists that systematize and automate access to accumulated scientific data, including literary sources. The sub-goals include solving the problem of organizing and storing archaeological data, implementing multilingual interfaces in the information system, organizing information support for field and laboratory archaeological research, transferring the physical (nondigital) historical data storage system to a digital system. “ArchaeoNomos” database allows to keep records, analyze, visualize, and interpret data on geoarchaeological sites of Irkutsk and the Irkutsk region.

Archaeological sites of Baikal region have rich collections of canid remains. By the Iron Age dogs become abundant in some Transbaikalia archaeological sites, especially in Xiongnu complexes. Ivolginsk Fortress is one of Transbaikalia's most important Xiongnu sites, where a dog is the first (in faunal collections of 1955–1974 excavations) and the fourth (in faunal collection of 2017 excavation) numerous among domestic animals. However, the dog remains from the site are not extensively studied. To address parts of this lacuna, this paper describes ten dog skulls from Ivolginsk Fortress. The purpose of study is to determine the morphological type of dogs living in the fortress during the Iron Age. Their skulls are similar in size and shape to those of East Siberian Laikas. For this reason, we made a comparison of skulls from Ivolginsk Fortress to those of East Siberian Laika of the early twentieth century, which showed the general similarity in morphological characteristics of these skulls. Therefore, all dogs from Ivolginsk Fortress were identified as northern (Laika-like) type of dogs. Also, as a result of the morphological description of the Ivolginsk skulls, two size groups of Ivolginsk dogs were identified. However, a comparison of the size of the skulls to body mass made it possible to divide the Ivolginsk dogs into three size groups: small-, medium- and large-sized individuals. The Ivolginsk dog population consisted primarily of medium-sized dogs, small and large dogs were not abundant. Moreover, Ivolginsk dogs differed by some morphological characteristics: relative snout length (dogs with short and medium-length snouts) and relative skull width (dogs with narrow and wide skulls). The comparison of skulls from Ivolginsk Fortress to Holocene skulls from Far East and Baikal regions showed the similarity of Ivolginsk skulls to Early Holocene skulls from Cis- Baikal archaeological sites (Pad Kalashnikova, Ust-Belaia) and Early Medieval skulls from Amur archaeological sites. It could indicate that dogs of northern type were relatively widespread during most of the Holocene in the Baikal and Amur regions.

Evaluating computer aided design tools for building performance: Trusting and defining the predetermined automated inputs
Authors: Newmarch ER , Bakshi Nilesh , Donn Michael
Published: July 2021

BIM use is on the rise in New Zealand with popular software packages, including Revit and ARCHICAD, adopting a semi-automated simulation platform. This allows architects and designers to calculate the thermal and energy performance of their designs. This paper identifies the strengths and weaknesses of these semi-automated simulation platforms. The objective is to investigate how accurate their assumptions are in determining a reliable output for use in achieving compliance with Clause H1 of the New Zealand Building Code. To achieve this, this paper reports a comparative study that examines the program’s ability to calculate construction R-values, interpret thermal properties and simulate energy performance. The results from this study show that if used as delivered there is a significant difference between the simulation results of the two software packages, due to the assumptions built into the default settings. It also identifies the disadvantages of the inbuilt construction R-value calculators and explores a potential path to resolving this through redefining the inputs of thermal properties.

Published: July 2021

create a melt pool on the substrate. A nozzle is used to carry metal powder within a gas flow until the melt pool, concentrating the flow at the same point. Coaxial nozzles usually have also a shield gas flow to prevent oxidation and an internal flow to protect the optical system. A right flow configuration must be selected to avoid high turbulence at the nozzle exit, leading to an efficient, inexpensive, and high-quality process. Due to the complexity of the process, CFD – Computer Fluid Dynamics are becoming necessary to understand the behaviour of those gas flows in DED processes. CFD can offer results close to reality and may allow an optimization of the whole nozzle designs, besides selecting the best gas flows for each application.
The present work develops a CFD simulation of the gas flow behaviour in a coaxial nozzle with three internal annular channels (internal, carrier and shield). An initial set of gas flow was selected, based on previous experience of the manufacturer, and then improved. It searches for the low gas consumption, to form a focal point coinciding with the laser focus and a low velocity, which favours the deposition quality. To check the accuracy of the proposed CFD model, experimental measurements of gas velocity were performed and compared with simulated results.

Authors: D. S. Guterres Natalino Fonseca , Rusnaldy  , Widodo Achmad , Syamsudin Arif
Published: July 2021

The chilled casting method is widely used in the metal casting industry to accelerate the mold's cooling rate. This method is very suitable for surface hardening by depositing the elements contained in the chill material onto the surface of the object being cast. One of the factors that influence surface hardness characteristics is the diffusion temperature. This study aims to determine the microhardness, surface layer thickness, and the element contained on the surface. The main material produced into Y-Block is ductile cast iron, the chill material is SS 304 plate with a thickness of 0.2mm. However, before the liquid material is poured into a mold, the chill plate is inserted into the surface of the pattern in the mold, then the plate was preheated. The result showed that the highest preheating temperature has produced microstructure around the surface area namely eutectic carbide of (FeCr)7C3, and (FeCr)3C. SEM-EDX analysis shows that 7.13%Cr is contained on the coating layer at a thickness of 0.020 mm and an average hardness of 700-900 HV.
Improving Heat Transfer from Peltier Devices Used in an Atmospheric Water Generation
Authors: Summers Mark , Asiabanpour Bahram
Published: July 2021

Present Atmospheric Water Generation (AWG) systems are useful for providing water in areas with limited water supplies. Many industrial AWG systems use VCR (vapor-compression refrigeration) to achieve a large amount of cooling to extract liquid water out of the air.  These systems require large amounts of energy to operate, usually in the form of diesel or AC-powered generators.  The systems also have many moving parts that require maintenance and use refrigerants that can leak and cause problems with the environment. An alternative AWG solution is to use DC-powered Peltier devices (thermoelectric coolers) to reduce the temperature of condensation plates to extract water from the air.  This solution eliminates the issues with traditional industrial AWG systems since the Peltier devices are solid-state, have very long mean-time between failure (MTBF) performance, and can be powered by solar panels that eliminate the need to burn hydrocarbon-based fuels or have access to a reliable power grid.  Also eliminated is the need to use chlorofluorocarbon (CFC) or hydrochlorofluorocarbons (HCFC) refrigerants that have been shown to deplete the ozone layer. This paper will present methods to improve the efficiency of the thermoelectric coolers by more efficiently extracting heat from the hot side of the device.  This efficiency will be quantified by evaluating the coefficient of performance (COP) of the thermoelectric cooler under the various operating conditions.  Different combinations of conductive heat transfer using aluminium heatsinks, convection heat transfer using forced airflow, and phase change heat transfer using copper heat pipes filled with distilled water will be investigated and evaluated.

Authors: Ochuokpa Ezekiel Otor , Sumaila D. S. , Adebisi Abdulmumin
Published: July 2021

A composite material is a combination of two or more chemically distinct and insoluble phases; its properties and structural performance are superior to those of the constituents acting independently. MMCs are made by dispersing a reinforcing material into a metal matrix to improve their properties. They are prepared by powder metallurgy and casting, although several technical challenges exist with casting technology. Achieving a homogeneous distribution of reinforcement within the matrix is one such challenge, and this affects directly on the properties and quality of composite. In this work a composite is developed by adding Mango seed shell Ash (MSSA) particulate in Al- Si-Mg Alloy by mass ratio 5%, 10%, 15% and 20%.  The composite was prepared by stir casting technique. It is proposed to use this material for production of motorcycle wheel hub which are subjected to continuous wear as the hubs are in direct contact with the brakes and rotating sprockets. The MSSA, was characterized using X- ray fluorescent (XRF). The result reveals SiO2, has the highest percentage composition followed by CaO, Al2O3, Fe2O3 and Mg2O as major phases. The presents of these hard constituent compounds suggests that the mango seed shell ash can be used as particulate reinforcement in various metal matrices since the chemical composition has similarity with the XRF analysis of Periwinkle shell ash, rice husk, fly ash, and bagasse ash currently used in metal matrix composite. Mechanical tests such as hardness test and impact test were conducted. The results revealed that increase in the percentage of MSSA progressively increased the hardness of the material from 5% wt to a maximum hardness of 43.2 HV at 15% addition of MSSA. This represents a 26.16% improvement over the unreinforced alloy. However, the impact energy progressively decreases of the material from 5%wt of MSSA and later increased to optimum energy at 15% addition of MSSA. From the results it is concluded that composite material such as Al- Si-Mg/ MSSA is one of the options as a material for production of motorcycle hub. The wear test of the composite was then carried out using Taguchi design to optimize the range of MSSA from 5% wt -15% wt., Sliding speed of 5cm/s -20cm/s, sliding distance from 50m to 200m, and the load of 2N, 4N, 6N, & 8N respectively. Analysis of the result of SN ratio for wear rate shows the optimum wear resistant value is in the combination of Load=4N, sliding speed = 10cm/s sliding distance=200m and MSSA=15 wt% These also correspond with the analysis of wear maps & wear rate presented in the diagrams of dynamic friction coefficient (COF) for Al-Si- Mg/ MSSA Composite.

Due to the increase in international communication with the developing technology, the interest in Turkish has increased like many other languages. Today, there are 135 Turkish language teaching centers serving foreign students within Turkish universities in Turkey. It is expected that various processes of these centers, which are gathered under the roof of YÖK (Higher Education Council) and serve the same purpose, will be carried out under certain standards. Because the language levels of the students are determined and certificates are issued, students can enroll in other universities with these certificates. This research was conducted to describe the assessment and evaluation processes of the centers teaching Turkish as a foreign language and to reveal whether they differ in terms of institution type and experience. The research was carried out with the document analysis method, one of the qualitative research methods. The data of the research consists of the websites of Turkish teaching centers and exam guidelines. The sample of the study was determined by the maximum variation sampling method. Descriptive analysis was applied in the analysis of the data. In line with the findings, it was concluded that the Turkish language teaching centers in public and private universities, the base points determined for language skills and the range of level scores were dissimilar. Among the results obtained is that the base points for language skills and the range of level scores for Turkish teaching centers with high and low experience are different.

Field investigations were conducted to assess the effect of conservation agricultural practices on soil biological properties and yield of cotton during the kharif season of 2018 and 2019. The experiments were laid out in a split plot design with four main factors viz., conventional tillage with irrigation schedule of 0.8 IW/CPE ratio (M1), conventional tillage with irrigation schedule of 0.6 IW/CPE ratio (M2), minimum tillage with irrigation schedule of 0.8 IW/CPE ratio (M3) and minimum tillage with irrigation schedule of 0.6 IW/CPE ratio (M4). Sub plot had six treatments of weed and nutrient management viz., crop residue mulch with 100% RDF (S1), crop residue mulch with 75% RDF (S2), pre-emergence application of pendimethalin fb one hand weeding with 100% RDF (S3), pre-emergence application of pendimethalin fb one hand weeding with 75% RDF (S4), mechanical weeding twice with 100% RDF (S5) and mechanical weeding twice with 75% RDF (S6). Total microbial populations viz., bacteria, fungal, and actinobacteria were higher in cotton rhizosphere soil with the minimum tillage of irrigation at 0.8 IW/CPE ratio (M3) in the main plot treatments. Cotton rhizosphere soil with crop residue mulch with 100% RDF (S1) recorded a higher microbial population and it was statistically similar with pre-emergence application of pendimethalin fb one hand weeding with 100% RDF (S3) in the sub plot treatments. Among the treatment combination, minimum tillage with irrigation at 0.8 IW/CPE ratio (M3) and crop residue mulch with 100% RDF (S1) recorded a higher microbial population. Similarly, a higher seed yield of cotton was also recorded with minimum tillage and irrigating the crop at 0.8 IW/CPE ratio and pre-emergence application of pendimethalin fb one hand weeding along with application of 100% RDF (M3S3)

The advent of Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) also known as COVID-19 disease and the dynamics of its rapid spread around the globe are unprecedented. Different preventive efforts have been undertaken in response to this global health challenge, amongst them, vaccine development, distribution and dispensation is at the forefront. Vaccines stimulate the body’s immune system against infectious pathogens; hence, they are one of the greatest medical accomplishments and a cornerstone of public health. There is a strong consensus globally that COVID-19 vaccine is likely the most effective approach to sustainably controlling the COVID-19 pandemic. An unprecedented research effort and global coordination has resulted in a rapid development of COVID-19 vaccines. Here, we review the various types, Pros (status of different COVID-19 vaccines, their utility in COVID-19 control and as a tool of herd immunity or protection) and Cons (various side effects, leaky vaccination and vaccine hesitancy) of COVID-19 vaccines. Despite all cons it is believed that vaccination will certainly help in building up of herd protection against COVID-19 disease, which could allow lockdowns, travel restrictions and social distancing to be relaxed globally.

Student academic achievement is a very important matter for all school parties that are directly or indirectly related, especially for Depok Tourism Vocational School, student academic achievement is one of the benchmarks in the success of education. Currently, the process of determining student achievement from the academic side of the Depok Tourism Vocational School is still using a manual system, so it takes a long time to determine the assessment of student academic achievement, because there are quite a lot of student data recording. In addition, it is still less relevant because it has not used the right calculation method, resulting in inaccurate calculations. This research uses the Technique For Order Preference by Similarity to Ideal Solution (TOPSIS) method, because this method is a simple concept and easy to understand and to help the optimal decision-making process to solve practical decision problems. The results of the research using the Technique For Order Preference by Similarity to Ideal Solution (TOPSIS) method found that students with the name Akmal Adnanto got the first rank with the highest preference value of 0.760.

Introduction: To improve the first step of the hospitalization procedure, appropriate interaction must be established between users and the admission, discharge, and transfer system. The aim of this study was to evaluate the usability of the ADT system in some of selected Iranian non-teaching hospitals.Material and Methods: This study was cross-sectional research that has evaluated the usability of a selected ADT system using the think-aloud method by 11 medical record administrators. Users were asked to follow the provided scenario, then share and elaborate on what they saw, thought about, did, felt, and decided during their interaction with the system. Users' feedbacks were collected and organized into four main categories for further processing.Results: To evaluate the usability of an ADT system, four routine scenario tasks were followed by users and only 45.45% of them could implement all tasks. Overall, 36 independent problems were identified. All problems were related to the data entry categories that accounted for the largest share. The most important problems were related to the issues regarding "date of birth" field in this category which deals with the outpatient admission process.Conclusion: The study of the usability testing method indicated that the ADT subsystem of non-teaching hospital has many problems in interact with real users with the system. It showed that more than half of the users could not completely and successfully perform the entire real-world scenario tasks. Furthermore, the most usability problems were found in data entry categories.
Imaginary novelty and its affirmation in culture

Published: July 2021

The study of novelty as a cultural phenomenon presupposes the formulation and solution of the problem in the ultimate interpretation, as an unbiased description of its appearance on a defined territory, reducing it to preestablished principles that explain novelty as certainty and stability. This means understanding the phenomenal limit-the novelty goes to infinity and shimmers in the vastness of being, appears to the inquisitive mind in the form of original discoveries and imaginary worlds. Novelty is revealed as the opening potency of being with the possibilities that have appeared – the reversal of events that are its direct implementation. The formulation of the novelty problem immediately confronts the initial contradiction and the difficulty of solving it. Imaginary novelty compensates for the unavailability of a material analog-it fills the voids of being and presence with its creations. Imaginary novelty carries the desired illusions that inspire the enthusiast, but under the cover of dreams, the real novelty of being grows. The paper suggests the related concepts: imaginative, imaginary, quasi-objective for the expansion of the intellectual landscape of the field of culture. In the aspect of novelty, the imaginary appears as an outstripping development of the presence, its separation from being and self-active bifurcation, the desire for a new material embodiment – the production of added being.

Innovating the Music and Sound Management Model in Tourist Destinations
Authors: Grgurić Diana , Stipanović Christian
Published: July 2021

This paper presents an analysis of the current level of sound and music valorisation in offerings in Croa-tian tourism and their promotion, and proposals for innovation, among which emphasis is placed on an audio management model based on the principles of acoustic ecology. Croatia is one of the more competitive Mediterranean destinations, focused on cultural tourism in which music offerings have a vital role. The first phase of research is based on in-depth interviews with and surveys of the representatives of tourist boards in Croatia, as a starting point for the situation analysis of music valorisation in Croatian tourism. The second phase is based on in-depth interviews with a target sample of tourist board repre-sentatives regarding music development as well as on the authors’ views based on recent scientific literature sources. The results of the study can be considered on two levels: the theoretical level, at which a management model for music valorisation in tourism is defined, and the practical level, with situation and scenario analysis of music valorisation in Croatian tourism and the design of an audio management model based on synergistic networking at both the micro-destination level and at the stakeholder level in order to diversify the attractions of the musical offering and create an integrated tourism product. Research results confirm that music has an insufficient position in strategic thinking in developing Croatian tourism, despite awareness of the considerable impact of music on the tourist experience in Croatia.

Reading the Biopic through Persona: A Comparison between "Bohemian Rhapsody" and "Rocketman"
Authors: Andrews Hannah
Published: July 2021

Personas are the public expressions of a private identity, the performance of personality in the social world. They are particularly visible and familiar in the world of celebrity, where entertainers regularly adopt an alter-ego for performance. This has intriguing consequences for biographical representations of performers. Biopic actors are obliged to duplicate the public-facing persona, which is an already-known, semi-fictional construction, and the private individual beneath. The narrative of the biopic must account for this relationship between the persona and the person who authors it. This article explores this process in two high-profile rock biopics, Bohemian Rhapsody (2018) and Rocketman (2019), comparing their different approaches to reproducing and exploring the persona of their subjects in performance, style and mise en scène.

Thus, the study assessed the utilization of family planning methods among rural women in Ogun State.  Multistage sampling technique was used to select 120 respondents and structured questionnaire schedule was used for the data collection. Data collected were analysed using both descriptive and inferential analysis.Result shows that majority of the rural women had mean age of 33±10, 45.0% were Muslims, 57.5% had secondary education, 77.5% married, 50.0% traders, 39.1% had between 5 and 6 persons in their households, 42.5% earned between 35,001 and 60,000 monthly and 66.7% of the were member of social association. Also, 60.8% had low awareness of contraceptive methods. In addition, 56.7% had high knowledge of family planning methods, most of the rural women sourced information on family planning through television. Also, increase in weight experienced by the respondents were the health factors militating against the utilization of family planning methods by the rural women as 50.8% had high utilization of family planning methods used by the rural women. There was a significant relationship between member of social association (?2=4.268, p<0.05), awareness of contraceptive method utilize by rural women (r=0.761, p<0.05), knowledge (r=0.617, p<0.002), source of information (r=-0.119, p<0.05), factors (r=0.201, p<0.05) and level of utilization of family planning methods.It is therefore concluded that most of the women had high knowledge of family planning methods but only utilized the commons ones available to them. It is therefore recommended that educative trainings should be organized for the women to enhance their usage of other methods to ensure a secured child bearing.
