Ade2 Functions in the Drosophila Fat Body To Promote Sleep
Authors: Yurgel Maria E , Shah Kreesha D , Brown Elizabeth B , Burns Carter , Bennick Ryan A , DiAngelo Justin R , Keene Alex C
Published: January 2019

Metabolic state is a potent modulator of sleep and circadian behavior, and animals acutely modulate their sleep in accordance with internal energy stores and food availability. Across phyla, hormones secreted from adipose tissue act in the brain to control neural physiology and behavior to modulate sleep and metabolic state. Growing evidence suggests the fat body is a critical regulator of complex behaviors, but little is known about the genes that function within the fat body to regulate sleep. To identify molecular factors functioning in non-neuronal tissues to regulate sleep, we performed an RNAi screen selectively knocking down genes in the fat body. We found that knockdown of Phosphoribosylformylglycinamidine synthase/Pfas (Ade2), a highly conserved gene involved the biosynthesis of purines, sleep regulation and energy stores. Flies heterozygous for multiple Ade2 mutations are also short sleepers and this effect is partially rescued by restoring Ade2 to the Drosophila fat body. Targeted knockdown of Ade2 in the fat body does not alter arousal threshold or the homeostatic response to sleep deprivation, suggesting a specific role in modulating baseline sleep duration. Together, these findings suggest Ade2 functions within the fat body to promote both sleep and energy storage, providing a functional link between these processes.

Published: January 2019

Development of accurate and practicable methods of land surface temperatures (LST) mapping has benefits for a range of scientific and practical applications. The paperconsiders mapping of LST for the Bystrytsia river basin located in Western Ukraine using Landsat 8 imagerywith two thermal infrared bands, which capture emissivity values closely related to land surface temperature (LST).Three multispectral images referring to different seasons (autumn, winter and summer) were used in the study. The method of LST estimation consists of several successive steps. After preprocessing (clipping, masking, and re-projecting), the images were converted from digital numbers to top of atmosphere spectral radiance,and then – to brightness temperature.However, the brightness temperature differs from LST due to emissivity of land surface being different from that of ideal blackbody.The emissivity can vary significantly with vegetation, surface moisture and surface roughness, and can be approximately estimated from land surface reflectivity at red and near-infrared spectral ranges. Estimated values of LST were compared with measurements of Ivano-Frankivsk state weather station, showing rather good compliance for all the three scenes.Obtained estimates of LST show some regularities of its spatial distribution, which also vary significantly from season to season.All the three scenes show conspicuous vertical gradient in LST; summer and autumn scenes are also characterized by significant local variability in LST due to different land cover types (e.g., urban development, forests, different agricultural lands), whereas in winter, differences in LST for mountainous slopes of different aspects appear to be more pronounced. Graphs of LST change with elevation have a parabolic form: sharper decrease of LST is typical for lower elevations, while the vertical LST gradient decreases above 700–1000 m a.s.l.

Published: January 2019

On the basis of the analysis of the literature sources, we determined the possible range of using the method of the Earth`s natural pulse electromagnetic field. As a result of detailed analysis of domestic and foreign research, we demonstrated the relevance of conducting research focused on development of the Earth'snatural pulse electromagneticfield (or ENPEMF). Using the results of theoretical studies, the advantages and disadvantages of the ENPEMF method were determined. A complex of physical processes which preceded the development of the pulse electromagnetic field of the Earth was characterized, and the impact of mechanical deformations of rocks on the change in the condition of the electromagnetic field was experimentally proven. The main fundamentals on the determination of depth range of the ENPEMF method were examined and a new approach to interpretation of the data was suggested. We conducted an analysis of methods developed earlier of calculating geometric parameters of the sources which generate electromagnetic impulses. Their practicability at a certain stage of solving the data of geological tasks was experimentally tested. We determined the factors which affect the depth range of the ENPEMF method. A mathematical solution of the effectiveness of the ENPEMF method was suggested and determined the relations between the depth parameter of the study and the frequency of measuring and effective value of specific electric resistance. On the example of different objects, the effectiveness and correctness of the suggested method of determining the depth range parameter was proven. In particular, the theoretical results of the study were tested and confirmed on objects of different geological-morphological and engineering-technical aspects, i.e. Novo-Holyn mine in the Kalush-Holynske potash deposit and the multi-storey educational building of the University in Ivano-Frankivsk. The practicability of using the ENPEMF method in combination with other methods of electrometry for solving practical geological tasks was experimentally proven.

Published: January 2019

Remote sensing methodology was applied to assess two land cover parameters (elevation and soil moisture) in the first stage.Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) was used to build a map of the water catchment basins within the Wadi El K'sob area. Relative soil moisture for the territory of the Wadi El K'sob catchment area was estimated by using the Sentinel-1/Multispectral Instrument (MSI) and Landsat-8/Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) optical multispectral data. Elevation data of the sampling points range from 398 to 1081 meters above sea level. Soil moisturevaried from 0.2 to 0.37 relative units. The effects of altitude and physico-chemical properties of soil on soil microflora communities in the catchment area of Wadi El K'sob M’sila (Algeria) were investigated in the second stage. The work presented here identified three groups of microorganisms in the soil samples collected in spring 2017from 7 locations situated in the catchment area of Wadi El K'sob M’sila (Algeria) along with 11 physico-chemical characteristics. Statistical tests showed that actinomycetes, fungi and mesophilic bacteria were positively correlated to the altitude. The results revealed that the microflora communities was very dependent on soil physico-chemical characteristics, the main parameters were relative soil moisture, texture, pH, electrical conductivity, organic carbon, organic matter, total nitrogen and available potassium. Generally, the parameters analyzed in this study, indicate a change in the soil microflora community according to the altitudinal and soil physico-chemical variations.

Published: January 2019

Wire electro discharge machining (WEDM) is one of the most productive non-traditional machining processes. Complex shapes can be cut through the WEDM process. In the present study, attempts have been made to study the effects of various process parameters of WEDM such as pulse on time (T on), pulse off time (T off), servo voltage (SV), wire speed (WS) and servo feed (SF) on the material removal rate (MRR) and surface roughness (SR) for machining of TiNiCo shape memory alloys, traditionally used as bone staple material. Grey-relational-analysis-based entropy measurement methods were used for formulating a hybrid combination of optimisation methods, in order to investigate the input parameters of WEDM on the comprehensive performance of a bone staple material’s SR and MRR. Experiments were carried out by using response surface design (L-33), and the input parameters were ranked based on the grey relational grade. An experimental run was conducted using the optimal combination of input parameters of WEDM, which was obtained from the analysis. T on of 125 μs, T off of 42 μs, SV of 40 V, SF of 2180 machine units and WS of 4 m/min were obtained as the best combination of input process parameters for TiNiCo alloy.
Determinants of non-compliance with structural building code standards in Nigeria
Authors: Agapiou Andrew , Yakubu Sunday
Published: January 2019

This paper examines the determinants of non-compliance with structural building code standards and regulations within residential development projects in Nigeria. The study targets all stakeholders in development projects, and data were collected using stratified sampling and through the administration of 600 paper-based questionnaires to construction professionals and other stakeholders. A total of 378 valid questionnaires were utilised, representing a valid response rate of 63%. The following indicators were identified and investigated through quantitative analysis: corruption, capacity building, employment/financial strength, professional rivalry, professional vested interests, technological expertise, professional involvement in decision-making, human rights and public opinion from the earlier research in Nigeria. Using SPSS software with the Amos add-on, factor analysis and structural equation modelling were employed to investigate the data, which revealed that corruption, professional rivalry, professional vested interest and professional involvement in decision-making as a combined administrative factor were the most influential in leading to non-compliance with building code standards in residential development projects in Nigeria, followed by training and, to a lesser extent, sociological factors. In response to the findings, this study develops credible and acceptable enforcement control policy framework practices to improve the administrative and technical failure aspects of building standards and regulatory compliance in residential development projects.
Output Feedback Algorithm for Nonlinear Systems with Compensation of Bounded Disturbances and Measurement Noises
Authors: Furtat I. B. , Gushchin P. A. , Peregudin A. A.
Published: January 2019

The output feedback algorithm for dynamic plants with compensation of parametric uncertainty, external disturbances and measurement noises is synthesized. The plants are described by a nonlinear system of differential equations with vector input and output signals. Unlike most existing control schemes in this paper the dimensions of the measurement interference and the output signal are equal, the sources of the signals of disturbances and disturbances are different, parametric and external disturbances can be present in any equation of the plant model. For simultaneous compensation of disturbances and measurement noises it is proposed to consider two channels. On the first channel a part of the measurement noises will be estimated which will allow partial recovery the information about the plant noisy output. On the second channel the disturbances will be compensated. Thus, at least two independent measurement channels are required for simultaneous compensation of disturbances and measurement noises. Sufficient conditions for calculating the parameters of the algorithm in the form of solvability of the linear matrix inequality are obtained. It is shown that the equation of a closed-loop system obtained on the basis of the proposed algorithm depends on the disturbances and the smallest component of the measurement noise. However, if the smallest component cannot be identified a priory, the results of the transients depend on the component of the noise that will be selected in the synthesis of the control system. Thus, unlike most existing control schemes, where the equation of a closed-loop system depends on disturbance and noise, the resulting algorithm provides better transients, because they do not depend on the entire noise vector, but only on its smallest (one) component. The simulations for a third-order nonlinear plant and the synchronization of an electrical generator connected to the power grid are presented. Numerical examples illustrate the effectiveness of the proposed scheme and the robustness with respect to random components in the noises and disturbances.

Published: January 2019

The article deals with the problem of internal migration in the conditions of hybrid war in modern Ukraine. It is affirmed that the problem of migration is one of the tests for Ukrainian society on the ability of consolidation. The complex of problems generated by the resettlement of people from temporarily occupied territories is outlined and the author's understanding of their essence and the ways of solving is given. It has been proved that internal migration, as well as external, caused by the state of human depersonalization, which is the result of certain objective and subjective reasons, the most terrible of which is the war. The quantitative and qualitative composition of internally displaced persons in modern Ukraine, types of displacements, and also the reasons for choosing a certain vector of movement are determined. The gender imbalance of internal migration and its causes were revealed. The main problems of internal migrants are identified, namely: the search for housing, employment and integration into the new socio-cultural environment. In estimated the possibilities of solving the above-mentioned problems and determined the leading help agents are determinate. It is emphasized that in the process of resettlement and arrangement in a new place the state plays a minor role. The leading role belongs to volunteers and public organizations. It is revealed that in general the process of resettlement of citizens from temporarily occupied territories of Ukraine takes place without significant conflicts, and Ukrainians are adequately responding to the challenges of internal migration. It was emphasized that the hybrid war raises a number of problems, but also opens up the possibility of consolidation and solidarity of Ukrainian society. Direct communication of people from different regions destroys stereotypes and promotes the integration of Ukrainians. The accent is on redefining the citizens' attitude towards Ukrainian statehood, state independence and national-state symbols. It is established that the degree of consolidation is growing in crisis conditions, and in the current situation in Ukraine, consolidation also implies unity with other countries that support the civilizational choice of our Motherland.
NATIONAL IDENTITY AS ONE OF THE FACTORS CONTRIBUTING TO THE CONSOLIDATION OF THE UKRAINIAN SOCIETY: DMYTRO CHYZHEVSKYI AND YURIY SHEVELIEV (HISTORICAL AND CULTURAL CONTEXTS)
Authors: Valiavko Iryna
Published: January 2019

The study analyzes the phenomenon of national and cultural identities, which acquires the meaning of the fundamental mode of human existence in the modern globalized world. The "hybrid war", in which Ukraine has been involved for more than 3 years, has directed its citizens not only to discover their national and cultural identities but also to determine their civic position. During such critical historical times, a special attention is given to outstanding personalities, with whom the nation identifies itself and who embody its creative potential. Among such "iconic figures" of the Ukrainian nation, we recognize the following thinkers and prominent scholars: philosopher, Slavist, and scholar Dmytro Chyzhevskyi (1894-1977), and linguist, historian, literary critic Yuriy Sheveliev (1908-2002). Dmytro Chyzhevskyi and Yuriy Sheveliev made a significant contribution to the study of Ukrainian culture. They have introduced achievements of the Ukrainian culture to the world, and it enabled an adequate perception of Ukraine as an independent state. Each of them had a significant influence on a number of famous Slavists and linguists from the leading world universities, who continued the study of the Ukrainian culture. Both scholars deliberately chose their national identity and popularized Ukrainian culture during the period of protests and the ethical impossibility of separation. It was a hard time of denial and destruction of Ukrainian culture. This historical period reminds us the current situation in Ukraine, when on the wave of the "hybrid war" and protests against the aggressive Russian occupation manycitizens got intothe "Ukrainization" process. Ukraine was delighted to have among those who identified themselves as Ukrainians such world-class thinkers as Dmytro Chyzhevskyi and Yuri Sheveliev.

Published: January 2019

In the article the formation of the personality cult of the president of modern RF V. Putin is observed, whom a great number of analysts in Ukraine and in the world is called a new personal dictatorship in the former Soviet Union. The inseparability of the establishment of a dictatorial regime from the Kremlin's neo-imperial policy, which has already become known as "Putinism" and "racism", is analyzed. The gender analysis methodology is used to identify the grounds for mass perceptions of dictatorial regimes by the population of the State. Pointing to the dangers of the Kremlin's dictatorial regime for Ukraine's democracy and independence. To substantiate the main provisions of the study, an analysis of a particular material from the current reality of the RF is used. Historical parallels between the dictatorships of the past and present, including the dictatorial regime of A. Hitler, I. Stalin, F. Castro, are conducted. It is concluded that in the situation with dictators for their countries there is a serious danger. But today, due to Russia's technical capabilities, mortal danger can become a reality not only for the loyal dictator of the people. But for Ukraine and the world.

The article analised the use of the potential of the scientific diaspora is one of the modern approaches to the modernization and integration into the world scientific space of the scientific systems of many countries, including posttotalitarian, in which the transformation of the social system is accompanied by a decrease in the financing of science, theof science, thereduction of the scientific and technical branch and exit promising young scientists into research centers of richer countries. Such negative tendencies for many years are inherent in Ukrainian science, as evidenced by a number of studies. The authors considered the role of cooperation with the scientific diaspora as a factor in the consolidation of high-ranking Ukrainians. The activity of the Ukrainian Academic International Network is analyzed and examples of best practices of scientific cooperation are presented. The importance of attracting the intellectual potential of the scientific diaspora to the processes of reforming and developing education and science in Ukraine is emphasized. It is concluded that the list of best practices of scientific cooperation initiated by our scientific diaspora testifies to its desires and possibilities to contribute to the development of science and education in Ukraine and to promote their inclusion in the European and world research field. Given the current difficult financial situation in the country, this contribution can be a powerful determinative stimulus to ensure further reform and development of the country's economic and intellectual environments. Functioning of academic networks created by academics unites scientists in Ukraine and beyond, and is an example of the consolidation of high-class Ukrainians in general. The role of cooperation with scientific diaspora as consolidation factor of highly professional Ukrainians is discussed in the article. Activity of the Ukrainian Academic International Network is analysed and the examples of best practices of research cooperation are presented. The emphasis is put on the importance of attraction of scientific diaspora intellectual potential to reforming and development of education and science in Ukraine.

Numerical and Experimental Investigation of Laminar One-Dimensional Counter-Flow Flames Using Product Gas From Pyrolysis and Gasification of Woody Biomass
Authors: Scharl M.-T. , Greenhalgh D.A. , Dieguez-Alonso A. , Behrendt F.
Published: January 2019

Further advances in the utilization of biomass-based gaseous fuels in combustion systems require a deeper understanding of the combustion chemistry behind, as well as of the coupling of the chemistry with physical phenomena such as turbulence. The former is investigated in the present study combining both experiments with numerical simulations of different types of laminar non-premixed flames (sooting and non-sooting) in a counter-flow setup. The focus is put on synthetic gas mixtures, resembling, to different extents, typical compositions of the product gas obtained in biomass gasification consisting of CH4 (reference) and CH4 mixed with CO2, N2, O2, and/or H2, always. The oxidizer in all cases is air. A wide range of air-fuel ratios is considered. The influence of the product gas composition on the flame behaviour and flame structure with respect to the changes of the species profiles and peak temperatures with changing flow velocities is discussed. Laser-based spectroscopy techniques, in particular laser-induced Rayleigh scattering and laser-induced fluorescence (LIF), are applied as diagnostic tools. The former can provide an accurate understanding of temperature distributions, while the latter helps to identify the flame front through the tracking of intermediate species, such as CH2O (formaldehyde). Additionally, CH* chemiluminescence contributes to localize the flame front. Lastly, the influence of the N2-shroud flow velocities and diameters, as well as resulting buoyancy effects due to a raise in temperature, are taken into account. In correspondence to these experiments, the flames are numerically simulated by an in-house time-dependent implicit Fortran code.

The research of a spent kieselgur obtained during beer filtration as a sorbent for cleaning of waste waters from oil. The thermal processing of a spent kieselgur influences over its ability to remove oil in the process of cleaning of waste waters. It has been discovered that the highest degree of removing oil from standardized test solutions of waste waters is provided by a spent kieselgur modified at a temperature of 400 °C. Modifying a spent kieselgur with sulphuric, hydrochloric and phosphoric acids at different temperatures increases its sorption properties in relation to oil. The maximum removal of oil from standardized test solutions of waste waters is achieved by using a spent kieselgur modified with 20 % sulphuric acid at 100 °С for cleaning them. Using a modified spent kieselgur allows increasing the degree of cleaning of waste waters contaminated with oil.

Obiekty ideologiczne w argumentacji aksjologicznej
Authors: Lewiński Piotr
Published: January 2019

Argumentacja aksjologiczna odnosi się do kwestii dotyczących etyki, polityki albo estetyki. W tego rodzaju argumentacji źródłem gwaranta jest ogólna baza aksjologiczna, która składa się z przyjętych przez określoną grupę społeczną sądów wartościujących. Taki gwarant jest poparty przez ideologię, rozumianą jako względnie dobrze zorganizowany zbiór sądów wartościujących usankcjonowanych w ramach danej kultury. W argumentacji aksjologicznej sądy są reprezentowane przez obiekty kulturowe, które służą jako argumenty. Podklasą obiektów kulturowych są obiekty ideologiczne. W dyskursie argumentacyjnym używa się definicji wartościujących, w których poszczególne obiekty indywidualne grają rolę definiendum, podczas gdy definiens jest reprezentowany przez nacechowane emocjonalnie obiekty ideologiczne. Głównym celem tego rodzaju dyskursu nie jest zmiana przekonań, ale indukowanie w odbiorcach emocji, które odwołują się do ideologii wyznawanych przez grupę, do której należy nadawca. Celem niniejszego artykułu jest pokazanie, w jaki sposób konstruowane są obiekty ideologiczne i jak ich konstrukcja wpływa na emocjonalną podstawę argumentacji.
Aktywacja standardów osobistych odbiorcy jako ograniczenie dla występowania efektu perswazyjnego komunikatu (na przykładzie message-matching effect)
Authors: Dobrosz-Michiewicz Karolina
Published: January 2019

Artykuł przedstawia wyniki serii badań eksperymentalnych nad wpływem aktywacji standardów osobistych odbiorcy na perswazyjność efektu komunikacyjnego, opartego na dopasowaniu regulacyjnym celu komunikatu i argumentacji w nim zawartej. Uzyskane w warunkach polskich wyniki wydają się stawiać pod znakiem zapytania przyjęte w tzw. value experience Edwarda Tory Higginsa założenie odrębności standardów osobistych i społecznych oraz zgodności regulacyjnej jako czynników równolegle warunkujących siłę zaangażowania człowieka w działanie. Efekt zgodności regulacyjnej wydaje się być bowiem przez powyższe moderowany.

Imponderabilia perswazyjne. (Poza)kognitywne uwarunkowania skuteczności argumentacji
Authors: Korżyk Krzysztof
Published: January 2019

W przedstawianym tekście omawiam kognitywne i pozakognitywne uwarunkowania skuteczności perswazji i argumentacji, które nazywam imponderabiliami perswazyjnymi, ze względu na dobrze znane trudności z operacjonalizacją ich oddziaływania w konkretnych sytuacjach problemowych. W związku z tym zajmuję się również konstytutywnymi elementami perswazji i omawiam ich własności z funkcjonalno-pragmatycznego punktu widzenia. W szczególności, zwracam uwagę na: 1) nieprzystawalność formalno-logicznych modeli argumentacji do realiów komunikacji perswazyjnej; 2) konieczność uwzględnienia w badaniach nad argumentacją i perswazją podmiotowej, zaksjologizowanej wizji rzeczywistości jako ważnego układu odniesienia dla funkcjonowania „środków dowodowych”; 3) niejednorodność strategii uzasadniania przekonań odwołujących się do różnych źródeł poznania; 4) wagę pytań filozoficznych związanych z tym, co nieuwarunkowane w ludzkim myśleniu i egzystencji. Całości dopełniają konstatacje dotyczące nie-dowodowej i nie-koniecznościowej natury argumentacji oraz roli krytycznej dyskusji w harmonizowaniu niewspółmiernych, podmiotowych wizji rzeczywistości partnerów interakcji.

Authors: Filipczak-Białkowska Anita
Published: January 2019

W artykule przyjmuje się, że luka informacyjna to pojawiający się w procesie interpretacji efekt, powstający wówczas, gdy tworzy się przestrzeń między wiedzą niezbędną do przeprowadzenia operacji dopełnienia sensu w procesie interpretacji komunikatu a wiedzą już posiadaną przez odbiorcę (jego bazą interpretacyjną). Ta przestrzeń może być niekorzystna z punktu widzenia odbiorcy, ale korzystna dla nadawcy. Jest to bowiem mechanizm, który pozwala nadawcy sterować działaniem odbiorcy w kierunku poszukiwania przez tego ostatniego dodatkowych informacji, które pozwolą zapełnić lukę informacyjną.W artykule testuje się hipotezę, że komunikaty charakteryzujące się określoną konstrukcją generują lukę informacyjną i przez to są postrzegane jako wywołujące większe zaciekawienie niż komunikaty pełne informacyjnie. Przedstawione są także rezultaty przeprowadzonego przez autorkę badania językowego oraz sporządzonej na potrzeby badania ankiety. Przyjęta hipoteza badawcza została potwierdzona w badaniu – większym zainteresowaniem cieszyły się tytuły, które generowały lukę informacyjną.
Perswazja w dyskursie gerontologicznym – przeszkody i strategie w komunikacji z pacjentem geriatrycznym
Authors: Ozga Krzysztof , Ozga Agnieszka
Published: January 2019

Prezentowany artykuł stanowi analizę przeszkód i strategii w dyskursie gerontologicznym. Autorzy dokonują krótkiego przeglądu spojrzenia na osobę starszą w świetle różnych dziedzin nauki i na tym tle proponują własną definicję dyskursu gerontologicznego jako całokształtu wypowiedzi osób starszych oraz wypowiedzi kierowanych do osób starszych wraz z sytuacją komunikacyjną, w której są one wypowiadane, oraz czynnikami determinującymi ich zakres tematyczny. Następnie przedstawione są podstawowe przeszkody w komunikacji z osobą starszą oraz strategie niewerbalne i multimodalne w komunikacji z seniorem. Zasadniczą część artykułu stanowią perswazyjne strategie werbalne w komunikacji: lekarz geriatra – pacjent, które omawiane są w porządku tematycznym w odniesieniu do ramy wizyty geriatrycznej – wolne tempo pacjenta, zaburzenia wzroku i słuchu, repetytywność i tendencja do odbiegania od tematu rozmowy, ból, komunikacja non-bona fide oraz zasada małych kroków. W tej części artykułu autorzy proponują także modyfikację skali IADL z perspektywy jej wartości perswazyjnej. Ostatnia sekcja artykułu poświęcona jest zagadnieniu perswazji w komunikacji z pacjentem z zaburzeniami pamięci i funkcji poznawczych, omawiana w świetle metody rehabilitacji poznawczej spaced retrieval. Analiza pokazuje, że perswazyjna wartość dyskursu gerontologicznego uzyskiwana jest dzięki strategiom wyodrębnionym na następujących jego poziomach: na poziomie sytuacji komunikacyjnej, na poziomie organizacji tekstu/dyskursu, w obrębie słownictwa, gramatyki i składni oraz na poziomie układu interakcyjnego.

Kilka uwag do biografii i działalności publicystycznej Marii Ilnickiej
Authors: Samborska-Kukuć Dorota
Published: January 2019

Biogramy Marii Ilnickiej, znanej przede wszystkim jako redaktorka „Bluszczu”, mają wiele usterek i niedookreśleń wynikających z zaniedbań kwerend archiwalnych, jak również pobieżnego zaledwie dotknięcia poszczególnych zagadnień. Niedostatecznie zbadana też została atrybucja manifestu powstańczego z 1863 r. –przypisanie autorstwa Ilnickiej. Dopowiedzeń wymaga także formuła propagowania konserwatywnego światopoglądu publicystki, stroniącej od ruchów emancypacyjnych, a projektującej kobietom bardzo wąskie pole aktywności, przez co „Bluszcz” był – wbrew powszechnym sądom – pismem niefeministycznym. Artykuł podejmuje te kwestie, pewne rozstrzygając, inne zaś sygnalizując.
Efficient Conversion of Glucose into 5-Hydroxymethylfurfural via a Simple Catalyst γ-AlOOH at a Mild Reaction Condition

Published: January 2019

A simple solid acid catalyst γ-AlOOH was employed to synthesize 5-hydroxymethylfurfural (HMF) from glucose in the dimethyl sulfoxide. Various reaction parameters, such as catalyst loading, temperature, reaction duration and solvent, were investigated. A high HMF yield of 61.24 % was obtained at the mild reaction condition of 130 °C for 3 h. More importantly, the catalyst γ-AlOOH could be reused for several times without the loss of its significant catalytic activities. After five reaction runs, a HMF yield about 57.23 % was obtained. In addition, the results demonstrated that the γ-AlOOH also had high catalytic activities on the degradation of other polysaccharides, like Maltose, Sucrose and Cellulose, into HMF using ionic liquid 1-butyl-3-methylimidazolium chloride, DMSO and a small amount of water as the reaction solvents. For instance, a high HMF yield of 50.26 % was obtained at 170 °C for 2.5 h on the decomposition of Cellulose.
Experimental Study on Drilling MDF with Tools Coated with TiAlN and ZrN

There is increasing use of wood-based composites in industry not only because of the shortage of solid wood, but above all for their better properties such as: strength, aesthetic appearance, etc. compared to wood. Medium density fibreboard (MDF) is a wood-based composite that is widely used in the furniture industry. The goal of the research conducted was to determine the effect of the type of coating on the drill cutting blades on the value of thrust force (Ft), cutting torque (Mc), cutting tool temperature (T) and surface roughness of the hole in drilling MDF panels. In the tests three types of carbide drills (HW) were used: not coated, TiAlN coated and ZrN coated. The measurement of both the thrust force and the cutting torque was carried out using an industrial piezoelectric sensor. The temperature of the cutting tool in the drilling process was measured using an industrial temperature measurement system using a K-type thermocouple. It was found that the value of the maximum temperature of the tool in the drilling process depends not only on the cutting speed and feed rate, but also on the type of coating of the cutting tool. The value of both the cutting torque and the thrust force is significantly influenced by the value of the feed rate and the type of drill coating. The effect of varying plate density on the surface roughness of the hole and the variation of the value of the thrust force is also discussed. The results of the investigations were statistically analysed using a multi-factorial analysis of variance (ANOVA).

Plant sugar is an essential dietary constituent for mosquitoes, and hemipteran honeydew is one of the many forms of plant sugar important to mosquitoes. Many insects rely on volatile honeydew semiochemicals to locate aphids or honeydew itself. Mosquitoes exploit volatile semiochemicals to locate sources of plant sugar but their attraction to honeydew has not previously been investigated. Here we report the attraction of female yellow fever mosquitoes, Aedes aegypti, to honeydew odorants from the green peach aphid, Myzus persicae, and the pea aphid, Acyrthosiphon pisum, feeding on fava bean, Vicia faba. We used solid phase micro-extraction and gas chromatography – mass spectrometry to collect and analyze headspace odorants from honeydew of A. pisum feeding on V. faba. An 8-component synthetic blend of these odorants and synthetic odorant blends of crude and sterile honeydew that we prepared according to literature data all attracted female A. aegypti. The synthetic blend containing microbial odor constituents proved more effective than the blend without these constituents. Our study provides the first evidence for anemotactic attraction of mosquitoes to honeydew and demonstrates a role for microbe-derived odorants in the attraction of mosquitoes to essential plant-sugar resources.
Small Molecule Docking of DNA Repair Proteins Associated with Cancer Survival following PCNA Metagene Adjustment: A Potential Novel Class of Repair Inhibitors
Authors: Peterson Leif E.
Published: January 2019

Natural and synthetic small molecules from the NCI Developmental Therapeutics Program (DTP) were employed in molecular dynamics-based docking with DNA repair proteins whose RNA-Seq based expression was associated with overall cancer survival (OS) after adjustment for the PCNA metagene. The compounds employed were required to elicit a sensitive response (vs. resistance) in more than half of the cell lines tested for each cancer. Methodological approaches included peptide sequence alignments and homology modeling for 3D protein structure determination, ligand preparation, docking, toxicity and ADME prediction. Docking was performed for unique lists of DNA repair proteins which predict OS for AML, cancers of the breast, lung, colon, and ovaries, GBM, melanoma, and renal papillary cancer. Results indicate hundreds of drug-like and lead-like ligands with best-pose binding energies less than -6 kcal/mol. Ligand solubility for the top 20 drug-like hits approached lower bounds, while lipophilicity was acceptable. Most ligands were also blood-brain barrier permeable with high intestinal absorption rates.  While the majority of ligands lacked positive prediction for Herg channel blockage and Ames carcinogenicity, there was considerable variation for predicted fathead minnow, honey bee, and Tetrahymena pyriformis toxicity. The computational results suggest the potential for new targets and mechanisms of repair inhibition and can be directly employed for in vitro and in vivo confirmatory laboratory experiments to identify new targets of therapy for cancer survival.
