Abstract The brlA gene of Aspergillus nidulans plays a central role in controlling conidiophore development. To test the hypothesis that brlA encodes a transcriptional regulator and to identify sites of interaction for the BrlA polypeptide, we expressed brlA in Saccharomyces cerevisiae (yeast) strains containing Aspergillus DNA sequences inserted upstream of a minimal yeast promoter fused to the Escherichia coli lacZ gene. Initially, a DNA fragment from the promoter region of the developmentally regulated rodA gene was tested and shown to mediate brlA-dependent transcriptional activation. Two additional DNA fragments were selected from an Aspergillus genomic library by their ability to respond to brlA in yeast. These fragments contained multiple copies of a sequence motif present in the rodA fragment, which we propose to be sites for BrlA interaction and designate brlA response elements (BREs). DNA fragments containing BREs upstream of a minimal Aspergillus promoter were capable of conferring developmental regulation in Aspergillus. Deletion of BREs from the upstream region of rodA greatly decreased its developmental induction. Multiple copies of a synthetic oligonucleotide with the consensus sequence identified among the BREs mediated brlA-dependent transcriptional activation in yeast. The results show that a primary activity of brlA is transcriptional activation and tentatively identify sites of interaction for the BrlA polypeptide.

Yeast cells with mutations in BRO1 display phenotypes similar to those caused by deletion of BCK1, a gene encoding a MEK kinase that functions in a mitogen-activated protein kinase pathway mediating maintenance of cell integrity. bro1 cells exhibit a temperature-sensitive growth defect that is suppressed by the addition of osmotic stabilizers or Ca2+ to the growth medium or by additional copies of the BCK1 gene. At permissive temperatures, bro1 mutants are sensitive to caffeine and respond abnormally to nutrient limitation. A null mutation in BRO1 is synthetically lethal with null mutations in BCK1, MPK1, which encodes a mitogen-activated protein kinase that functions downstream of Bck1p, or PKC1, a gene encoding a protein kinase C homolog that activates Bck1p. Analysis of the isolated BRO1 gene revealed that it encodes a novel, 97-kDa polypeptide which contains a putative SH3 domain-binding motif and is homologous to a protein of unknown function in Caenorhabditis elegans.

Machines and mechanisms contain units responsible for their movement and stopping, and such units use friction materials. These units include oil-cooled brakes, hydromechanical transmissions, and clutches. They use mainly copper-based friction materials providing the high coefficient of friction and wear resistance. These materials feature by effective heat dissipation since a large amount of heat is released in these areas for a short period of time. The paper presents the results of studies into the effect of iron addition into a frictional powder material based on BrO6 and BrO12 bronze on its structure, mechanical and tribotechnical properties. It was shown that the introduction of iron contributes to an increase in the coefficient of friction from 0.034 to 0.055 for the BrO6-based friction material and from 0.042 to 0.073 for the BrO12-based friction material. It was determined that the ultimate compression strength of the BrO12-based friction material is 340 MPa without iron addition, 310 MPa at 10 vol.% of iron, and 180 MPa at 50 vol.% of iron. This is due to the fact that the iron content of more than 30 vol.% results in the change of the frame structure of the material to the matrix one having a sintering temperature higher than the temperature used in the paper for friction material sintering. It was found that for the BrO6-based friction material there are both rounded and elongated inclusions in the copper phase up to 2.5 μm in size with the iron content of 30–50 %. In the BrO12-based material there are more iron inclusions in the copper phase and their size are much larger, the length of inclusions reaches 20 μm, and the iron content in them is 49–73 %.

Thin-walled pipes made of copper alloys – the brass grades L96, L68, L63, LANKMc; the bronze grade BrOF (the GOST state standard) are of great demand in aircraft, shipbuilding, automotive, defense, diesel and instrument-making industries. Pipe diameter ranges between 4.0 and 20 mm, and wall thickness is in the range from 0.1 to 0.6 mm. The manufacture of these pipes using traditional technological schemes is characterized by high labor input and low stability in providing quality characteristics, such as dimensional accuracy, the presence of surface defects and the level of mechanical properties. This study presents scientific evidence, new technological schemes developed for manufacturing pipes made of copper alloys with the use of the equipment and technology of multiple drawing on a long movable mandrel and results of their adoption at Revda Non-Ferrous Metal Processing Works JSC.

The analysis of tribological researches on the most perspective way of restoration of a primary resource of engines by means of a gas-dynamic spraying is resulted in article. It was found that to reduce the coefficient of friction and increase the wear resistance of the coating is theoretically justified the use of copper-zinc powders brand C-01-11, applied by gas-dynamic spraying. It is established that the physical and mechanical properties of the coatings (roughness, microhardness, friction coefficient) on the restored turbocharger meet the requirements of the manufacturer. The coefficient of friction in the connection, the rotor shaft (reduced powder with copper and zinc), with a plain bearing (made of tin-lead bronze Bros - 10 - 10) is 20 % less than in the connection where the rotor shaft is made of steel 40. The total wear in the bearing assembly with the restored gas-dynamic sprayed rotor shaft is 20 % lower than in the assembly where the rotor shaft is restored by the basic technology. The technology of restoration of a surface of a shaft of a rotor of the turbocompressor, under the bearing of sliding (gas-dynamic spraying) which increases its resource by 23 % in comparison with basic technology of repair of a shaft of a rotor is developed. This allows you to increase its operating time with the established regulatory and technical documentation for overhaul of the engine. A stand for testing diesel turbochargers with recovery technology has been developed, which allows to determine the parameters and characteristics of diesel engine turbochargers in different periods of operation, running-in and adjustment. Tests on the stand showed that turbochargers with restored rotor shafts according to the proposed technology after 2000 operating hours increase all performance by 13 % more than turbochargers repaired by the basic technology. Operational tests have shown that turbochargers repaired using the proposed technology have an operating time of 989 moto-hours more than turbochargers repaired with existing technology

The article presents the results of study of the effect of additives of an ultrafine powder of the Ti–46Al–8Cr system obtained by MASHS on the tribotechnical properties of a friction material based on BrO6 bronze. It is shown that in the range of powder additive concentrations 0.5–1.5 wt. %, the dynamic coefficient of friction increases from 0.04 to 0.055, in the range of 1.5–2.5 % – to 0.055–0.058. The introduction of the 0.5–1.0 % Ti–46Al–8Cr powder permitted to reduce the wear rate of the friction material from 4.0 to 3.7 μm/km. An increase in the additive to 2.5 % led to an increase in the material wear rate up to 6 μm/km.

Despite a very large variety of improvised firearms, repeatability of certain actions of the manufacturers can be observed, reflecting the purpose to which such weapons are produced (e.g. poaching), and the availability of appropriate technologies. The aim of this article is to make an attempt to systematize improvised firearms on the basis of the expert opinions elaborated at the Weapon Research and Ballistics Department of the Voivodeship Police Headquarters in Kraków (LK KWP) as well as studies carried out on weapons belonging to the collection of the Department of Forensic Medicine (ZMS) in Kraków. Research material included both primitive devices made by using simple methods and without concern for accuracy or aesthetics, as well as fine-tuned pieces with individual design solutions or copies of factory-made weapons. Improvised firearms can generally be divided into conversions and own designs. The conversion most frequently applies to alarm, gas or pneumatic weapons. It consists in removing factory safety mechanisms or, in the case of pneumatic weapons, in introducing technical modifications, which enable to blast off the cartridge and discharge the projectile by means of gas pressure arising during combustion of the propellant. Own designs may contain certain factory elements, most frequently the barrel, however, in most cases, they are manufactured from scratch. Improvised firearms, even those without the original elements, typically use ammunition with projectiles or, in some cases, the so called blank ammunition converted into live ammunition by adding projectiles.

Background: Bacterial pneumonia remains the major cause of morbidity and admission diagnosis among human immunodeficiency virus-infected individuals. In the study area, data about the bacterial profile of pneumonia and their antimicrobial resistance pattern among people living with human immunodeficiency virus is limited. Hence, this study was aimed to estimate the prevalence of bacterial pneumonia, antibiotic resistance patterns of isolated bacteria, and associated factors among HIV patients in Felege Hiwot Referral Hospital. Method: A Hospital-based cross-sectional study was conducted from February 15 to June 15, 2019. Sputum specimens were collected from 163 pneumonia presumptive HIV seropositive individuals. Data on socio-demographic characteristics and risk factors were also collected using a structured questionnaire. Blood, Chocolate, and MacConkey agar plates were used to grow the isolates. The isolated colonies were identified based on Gram Stain, colony morphology, hemolysis, and biochemical tests. The antimicrobial susceptibility test was performed using the modified Kirby-Bauer Disc Diffusion method. Descriptive and multivariate analyses were performed using SPSS version 23. P-value < 0.05 was considered statistically significant. Result: Out of 163 sputum samples, 68 (41.7%) were culture positive for common bacterial infections. The predominant bacterial isolates were Klebsiella pneumoniae 19 (27.9%), and Staphylococcus aureus, 17 (25%). From multivariate analysis, age groups 18-29 (AOR = 5.4, 95 % CI: 1.26-23.35), age groups 30-39 (AOR = 3.8, 95% CI: 1.03 13.80), recent viral load greater than or equal to 150 copies/ml (AOR= 24.3, 95 % CI: 2.61-56.38), viral load less than 150 copies/ml (AOR= 5.1, 95% CI: 1.26-21.04), cigarette smoking (AOR=15.5, 95% CI: 1.61-48.59), and alcohol consumption (AOR=8.1, 95% CI: 2.76-23.51) were found to have statistically significant association with bacterial pneumonia. Out of the tested antibiotics, 46 (70.8%) were resistant to cotrimoxazole and P. aeruginosa were 100% resistant to gentamycin and ceftazidime. Overall, 77.9% of the isolates were MDR. Conclusion: The study showed a high prevalence of bacterial pneumonia and a high percentage of drug resistance including MDR in the study area. Therefore, we recommend that culture and antimicrobial susceptibility tests should be routinely performed for the selection of appropriate treatment.

O crescente desenvolvimento industrial e urbano tem acarretado a introdução de grandes quantidades de metais nos ecossistemas aquáticos, expondo, potencialmente, sua biota e toda a cadeia alimentar que dela se origina à contaminação por esses elementos. Muitos estudos sobre o comportamento dos metais no meio aquático vêm sendo desenvolvidos, pois os metais representam um problema ambiental por sua persistência no ambiente e não biodegradabilidade. No entanto, pouco se conhece sobre seus efeitos ecológicos na estrutura e função das comunidades aquáticas. O presente trabalho, neste sentido, visa contribuir para um melhor conhecimento desses efeitos sobre a comunidade zooplanctônica em experimentos de campo que reproduzem, com maior fidelidade, o ecossistema. O objetivo deste trabalho foi avaliar os efeitos dos metais cromo e cobre sobre a estrutura da comunidade zooplanctônica de espécies holo-zooplanctônicas em experimentos de mesocosmos realizados na Represa do Lobo-Broa (CHREA/USP). Os mesocosmos constituíram-se de três cercados de filme de PVC transparente, com volume aproximado de 5000 litros, em contato com o sedimento de fundo. Um mesocosmos foi mantido como controle, não sendo contaminado, e os outros dois foram contaminados inicialmente com as concentrações máximas permitidas pelo CONAMA/86 para o cobre (20µg/L) e cromo (40µg/L). O experimento foi realizado de 28 de Março a 30 de Abril de 2002, quando amostras de água (para análises limnológicas) e plâncton foram coletadas duas vezes antes da contaminação e em intervalos de dois e três dias após a introdução dos metais. Na análise das amostras de zooplâncton foram contadas e identificadas as espécies dos três principais grupos zooplanctônicos (Copepoda, Cladocera e Rotifera), quantificados os ovos e classes populacionais de Cladocera e Copepoda, e posteriormente feitos os cálculos de diversos índices ecológicos. Os resultados obtidos indicam que as concentrações dos metais aplicadas causaram efeitos sobre a comunidade zooplanctônica. No entanto, estes efeitos foram diferenciados entre os diversos grupos e espécies observadas, sendo que para avaliar os efeitos sub-letais, uma análise populacional demonstrou ser mais eficiente do que índices ecológicos gerais. Apesar dos índices ecológicos terem demonstrado que os efeitos da contaminação por cromo foram mais severos sobre a comunidade zooplanctônica em relação ao cobre, os microcrustáceos apresentaram um melhor desenvolvimento no tanque contaminado cromo, sendo estes efeitos diferentes para as diversas espécies. Foram observadas alterações na abundância, produção e estoque de ovos de Calanoida, com efeito mais pronunciado no tanque contaminado com cobre. Os Cyclopoida foram mais resistentes à contaminação pelos metais, porém apresentaram sensibilidade diferenciada entre as espécies e entre os estágios de desenvolvimento. Em geral, os cladóceros foram mais sensíveis à contaminação, com efeito tóxico agudo em várias espécies, e efeitos crônicos para ambos os metais, avaliados pela redução no desenvolvimento e produção de ovos. Foram observadas ainda diferenças na sensibilidade entre as espécies de Cladocera, e a competição por recursos demonstrou ser um fator importante na sucessão de espécies nos mesocosmos. O cromo causou efeitos tóxicos mais acentuados sobre a maioria das espécies de Rotifera. A competição por recursos e a predação sobre Rotifera foram fatores importantes na estruturação de suas populações, sendo bastante influenciadas por efeitos indiretos causados pela contaminação do meio
The urban and industrial development has been contributing to the introduction of great amounts of heavy metals in the aquatic ecosystems, exposing its biota and the whole food chain to the contamination with these elements. A lot of studies about the behavior of heavy metals in the aquatic environment have been developed, since heavy metals represent an environmental problem due to its persistence and no biodegradability in the environment. However, little is known about the ecological effects of heavy metals on the structure and function of the aquatic communities. This work contributes for a better knowledge of these effects on the zooplankton community in field experiments. The purpose of this work was to evaluate the effects of chromium and copper on the zooplankton community structure in mesocosms experiments at the Lobo-Broa reservoir (CHREA/USP). The mesocosms were constituted of three 5000 liters transparent PVC littoral enclosures in contact with the bottom sediment. One mesocosms was maintained as control (not contaminated), and two were contaminated with the CONAMA/86 maximum concentrations allowed for copper (20µg/L) and chromium (40µg/L). The experiment was conducted from March 28 to April 30, 2002, when samples of water (for limnological analyses) and plankton were collected before and after the contamination in intervals of two to seven days. The zooplankton samples were counted and the species of the three main groups (Copepoda, Cladocera and Rotifera) were identified, eggs and population classes of Cladocera and Copepoda were quantified, and ecological indexes were calculated. According to the results, the concentrations of metals applied caused several effects on the zooplankton community. The ecological indexes showed that the effects of the chromium contamination were more severe over the zooplankton community than copper. However, the effects of the contamination were different for each metal, zooplankton group and species, and for the evaluation of these effects, the analysis based on population data was more efficient than the analyses based on ecological indexes. Copper caused more deleterious effects over the Crustaceans than chromium, but these effects were different for each species. It was observed a different sensibility among the species and the development stages of Copepoda. A more severe reduction in the population abundance and production of eggs of Calanoida occurred in the copper contaminated mesocosms than in the chromium one. Cyclopoida were more resistant to the metal contamination than Calanoida. Cladocera were the most sensitive group, reducing Its abundance and egg production in the contaminated mesocosms, and presenting acute and chronic effects for both metals. It was observed differences in the sensibility among the species of Cladocera, and the competition for resources demonstrated to be an important factor in the succession of species. Several species of Rotifera were more sensitive to chromium than copper, and indirect effects of contamination, like changes in the competition for resources and predation, were important factors in the determination of the Rotifera population structure

In 2014 Brazil will host the FIFA World Cup and Brasilia is one of the cities chosen to receive this mega sport event. Events like this, large scale and international repercussion, have great economic potential, but also generate environmental impacts. This study aimed to evaluate the environmental initiatives implemented in FIFA selected hotels in host city Bras??lia, focusing on reducing water and energy consumption and solid waste generation and checking how the hotels are being prepared for the 2014 "Green Cup". For this, a research was conducted by means of literature and surveys in 18 of the FIFA-accredited hotels for 2014 World Cup checking if hotels have environmental or sustainability certifications and if they accomplish environmental actions of consumption management of water, energy and solid waste in order to improve their environmental performance. As a result of the research it was found that most hotels do not have environmental certification, however most of them had good or very good environmental performance regarding environmental actions implemented focusing on reducing water and energy consumption and solid waste generation. It was concluded that these are performed in most hotels, but in isolation and with few environmental action planning.

This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building. A spatial analysis has also been made to distinguish any patterns of the distribution of material inside and around the house.The result of this essay is partly a presentation of the material, but also that there has occurred some bronze-crafting in the form of cutting metal sheets inside or near the foundation treated in this essay. There is no evidence for casting bronze near the house foundation.The frequency of finds from outside the foundation compared to the frequency of finds within the foundation is nearly quadruple, which is to be expected since there probably has been a wooden floor inside the house to prevent all but the tiniest objects from falling through. Objects that landed on the floor were cleaned out, just to land near the entrance of the building. The finds from within the building much resembles the finds from outside the building, and the distribution-patterns of the trench indicates that the entrance to the building probably was located near the north-west corner or near the south-east corner.Hopefully, this study contributes another piece to the great puzzle that is Västergarn.

This chapter assesses some interesting examples of diamonds. So far, the only example encountered is the self-product of copies of Spd Qp. The chapter first studies this self-product. It is useful to keep in mind that a diamond can have multiple “incarnations.” Another important class of diamonds, which in fact were one of the primary motivations for their definition, is the category of Banach-Colmez spaces. Recently, le Bras has reworked their theory in terms of perfectoid spaces. The category of Banach-Colmez spaces over C is the thick abelian subcategory of the category of pro-étale sheaves of Qp-modules. This is similar to a category considered by Milne in characteristic p.

Curtiz coped with a variety of tribulations with his daughter Kitty, who surfaced in Europe as a cabaret singer. After his daughter rejected her father’s entreaties and attemptedsuicide, Curtiz eventually helped her settle in London—without ever leaving the soundstages of Warner Bros. He directed The Case of the Curious Bride (1935), a Perry Mason mystery that briefly introduced the newcomer Errol Flynn to the screen.As the studio reorganized for greater efficiency and bigger pictures, Wallis tapped Curtiz to helm Captain Blood (1935). Robert Donat was signed to play the title role, but he fell out because of illness. There was nobody for it but Flynn, who made a smashing debut as the swashbuckling doctor-turned-pirate. Curtiz directed him ably, but his autocratic demeanor alienated Flynn, thus setting the stage for a difficult relationship between director and star. Wallis fought Curtiz for control of the production as the director continued to make the movie in hisown style,which was contrary to that of the executive producer.Emotions cooled when the picture became a hit; the profitable relationship of producer, director, and star boded well for the future.

Značaj konkurentnosti za povećanje razvoja zemalja, industrija i poduzeća u literaturi je gotovo općeprihvaćeno stajalište. Pritom, jedan od faktora koji se smatra ključnim za ostvarenje napretka na ljestvicama konkurentnosti zemalja odnosi se na reforme poslovnog okruženja. Iako je veliki broj zemalja postigao značajan gospodarski napredak kroz reforme prve generacije (liberalizaciju, makroekonomsku stabilizaciju, privatizaciju), pravi izazov predstavlja učiniti koristi ovih reformi održivima u dugom roku. Stoga su se reforme u većini zemalja počele usmjeravati na poboljšanje poslovnog okruženja čime se prvenstveno nastoji uspostaviti „kooperativni“ odnos između države, tržišta i civilnog društva. Glavni cilj ovog rada je stoga istražiti utjecaj reformi poslovnog okruženja na nacionalnu konkurentnost, na uzorku zemalja bivše Jugoslavije, plus Albanija. Za potrebe analize, osim makroekonomskih pokazatelja, usporedno se koriste baze podataka Svjetskog gospodarskog foruma (Izvješća o globalnoj konkurentnosti), Svjetske banke (Doing Business serija izvještaja, World Development Indicators, i Worldwide Governance Indicators), te EBRD-a (Transition Report). Empirijska analiza utjecaja reformi poslovnog okruženja na dinamiku konkurentnosti provesti će se kroz ekonometrijsku procjenu na panel podacima za odabrane zemlje.

Za veliki broj potencijalnih gostiju nekoga hotela u svijetu upotreba tražilica (Google, Baidu, Yandex... ovisno o zemljopisnom položaju) još uvijek je uobičajena svakodnevna rutina u fazi prikupljanja informacija o smještaju. Jedan od glavnih ciljeva web stranica svakog hotela je privući više gostiju od pretraživača – iz tog razloga važno je postići bolju vidljivost u okviru Internet tražilica. Bolja vidljivost podrazumijeva višu poziciju u okviru stranica rezultata pretraživanja (SERP- Search Engine Result Pages). Zbog svakodnevnog eksponencijalnog povećanja sadržaja na Internetu / širom svijeta, često je teško postići dobru vidljivost tražilice ili osigurati čelnu poziciju na stranicama rezultata lgoritamskih/ organskih pretraživanja. Dakle, svrha pisanja ovog rada proizlazi iz sve složenijeg utjecaja i važnosti algoritama tražilice, umjetne inteligencije i strojnog učenja na vidljivost u okviru Internet tražilica. Dizajn / metodologija / pristup - Na temelju prethodne / dostupne literature empirijsko je istraživanje provedeno pomoću jednog od najboljih svjetskih “all in one” softvera za analizu optimizacije na tražilicama - SEMrush. Rezultati istraživanja pokazuju (1) da je „vidljivosti na google tražilice” (položaj unutar SERP-a) ovisna o performansama web stranica hotela, te ukazuju (2) da je moguće detektirati i unaprijediti čimbenike koji determiniraju performanse web stranica hotela, a time i vidljivost na Internet tražilici. Ograničenja istraživanja odnose se na određeni uzorak istraživanja (hoteli s pet zvjezdica u Hrvatskoj) i faktor kratkog vremena pri provođenju istraživanja. U okviru budućih istraživanja trebala bi (1) povećati uzorak istraživanja i (2) istraživački proces treba proširiti i u kontekstu vremena i u kontekstu količine promatranih varijabli kako bi se pratile promjene u radu web stranica kroz duže vremensko razdoblje. Na taj bi se način višedimenzionalnom metrikom osiguralo kvalitetnije utvrđivanje međuovisnosti pojedinih varijabli i omogućilo donošenje relevantnijih zaključaka. U praksi, rezultati istraživanja predstavljaju vrlo realne smjernice za primjenu u svakodnevnom poslovanju.

Young adulthood is an important developmental stage in which individuals must go through a positive trajectory for a healthy and successful life. Young adult undergraduates in Sri Lanka face many stressors and adversities which affect their lives negatively. Therefore, it is important to determine the factors contributing to their resilience. Optimism is a factor that significantly enhances resilience. Moreover, there is a paucity of positive psychological and gender-sensitive research in the Sri Lankan context. In this sense, the present study aims to determine the relationship between psychological resilience and dispositional optimism among young adult undergraduates in Sri Lanka, the gender differences in resilience, and the gender differences in optimism. The instruments used were the Brief Resilience Scale (BRS) to measure resilience and the Life Orientation Test-Revised (LOT-R) to measure dispositional optimism. A total of 124 participants were involved in the study. The findings suggest that (a) there is a statistically significant moderately positive relationship between resilience and optimism (b) there are no gender differences in resilience between males and females (c) there are no gender differences in optimism among males and females. Importantly, the research provides practical implications for mental health practitioners, researchers, and positive psychologists to develop gender sensitive interventions to cope with stressors and adversities.
