Instability of petroleum oil degradation by induction of mutation in 45 kb and 60 kb plasmids

A strain of Pseudomonas sp. was isolated from oil‐contaminated soil on petroleum oil agar. This isolate used different alkenes and had two plasmids on gel agarose. These plasmids are probably involved in oil degradation. The mutant strain, which were obtained by sub‐culturing in nutrient broth (oil−), lost one plasmid (60 Kb) and had deletion in another plasmid (45 Kb). This result suggests that the ability to degrade petroleum oil must depend on these plasmids. The wild isolate has maximum OD of 2.5 for growth on petroleum oil, however the mutant did not have any significant growth on petroleum. GC Profiles of petroleum oil after degradation by wild and mutant were investigated.
A robust multi-scale gapped smoothing algorithm for baseline-free damage mapping from raw thermal images in flash thermography

Flash thermography is a promising non-destructive testing technique for the inspection of composite components. However, non-uniform heating, measurement noise and lateral heat diffusion complicate the interpretation of thermographic measurements. In order to overcome these difficulties, a novel baseline-free processing technique called ‘Multi-Scale Gapped Smoothing Algorithm’ is presented. This algorithm constructs a damage map directly from the measured data, in which an (almost) zero-reference background is obtained, and where measurement noise and excitation non-uniformity are effectively suppressed. The efficiency of the proposed technique is evaluated and confirmed through synthetic data and experimental results of a carbon fiber reinforced polymer with various artificial defects.
SHEAR PLASTIC DYNAMIC BEHAVIOUR OF WIND TURBINE TOWERS

The analysis of structures subjected to earthquake actions can be carried out by means of several methods with different levels of accuracy, among which the nonlinear dynamics is generally recognized as the most reliable one. This paper presents a general treat-ment to develop approximate solutions for rigid-plastic response of structures subjected to base harmonic pulse, by means of a numerical procedure on purpose developed. The case study is a vertical cantilever beam, with base support, constant mass and inertia distribution, subjected to only ground acceleration. The failure is assumed depending on the formation of a single shear hinge and the results are expressed in general terms. As a result, the motion proceeds through successive spreading and contractions of the plastic front and related elastic returns. Possible applications of the method to real structures can be envisaged.
Exploring the coach’s and athletes’ behaviour in martial arts

This descriptive study examined the processes of coaching and participation in Brazilian jiu-jitsu (BJJ) for both experienced (n=3) and novice (n=3) adult participants, members of a martial arts club in Finland. Over a period of six weeks, five practice sessions were videotaped with a mean duration of 84.35 minutes. Systematic observation data were used to describe the practice structure and participants’ engagement. Additionally, a modified version of the Coach Analysis and Intervention System was used to evaluate coaching behaviour. The heart rate data were also collected to evaluate the participants’ physical activity levels. Results indicated that practice time allocated to training and playing were 75% and 25%, respectively, which differs from team sport research. The coaching emphasis observed in this study highlighted competition and technique perfection. The participants’ practice activity level was high with most participants spending more than half of practice time at a moderate-to-vigorous physical activity level. These findings show that both the structure and content of coaching practice is context specific and that the coach need to identify and react to the needs of individual athletes.
Molecular dynamics study of the Ag6 cluster using an ab initio many-body model potential

A general approach to construct a model potential with parameters fitted to ab initio energy surfaces, including many-body nonadditive effects, developed in our previous works is applied to the Ag6 cluster. A molecular dynamics study of structural and dynamical properties of this cluster is performed using such a potential. Two new stable two-dimensional isomers with C2v and C2h symmetries are identified as local minima of the potential surface using the simulated quenching technique. An analysis of the thermal stability as a function of the cluster temperature reveals interesting features in the meltinglike transition of Ag6. A two-step isomerization phenomenon is observed: at temperatures around 300 K, the cluster structures fluctuate among two-dimensional isomers, at higher temperatures (500 K), fast transitions occur between two- and three-dimensional cluster configurations. The simulation was extended up to the cluster fragmentation which is observed through dimer evaporation.
A 4.4-mA ESD-Safe 900-MHz LNA With 0.9-dB Noise Figure

A 900-MHz 1.2-V 4.36-mA low-noise amplifier (LNA) with a minimum of 0.92-dB noise figure (NF) at 868 MHz, −12-dBm IIP<sub>3</sub>, with one inductor (external) is demonstrated. The circuit achieves narrowband input matching on a wideband LNA without inductive degeneration. A new half-cascoding technique is used to improve the input matching (<inline-formula> <tex-math notation="LaTeX">$S_{11}$ </tex-math></inline-formula>) while simultaneously achieving sub-1-dB NF performance. The 0.13-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> CMOS LNA is fabricated with embedded electrostatic discharge (ESD) protection diodes that add 60- and 80-fF loads at the RF input and output ports. At 868 MHz, the packaged LNA has a measured input return loss (<inline-formula> <tex-math notation="LaTeX">$S_{11}$ </tex-math></inline-formula>) of −18 dB and the transmission gain (<inline-formula> <tex-math notation="LaTeX">$S_{21}$ </tex-math></inline-formula>) of 14.2 dB. At 900 MHz, the LNA has a measured NF of 0.98 dB. The LNA (excluding the buffer) occupies an area of 0.047 mm<sup>2</sup>. The chip passes the human body model (HBM) test with an ESD zap of 2.5 kV within 10% margin of its prezap <inline-formula> <tex-math notation="LaTeX">$I$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$V$ </tex-math></inline-formula> characteristics, under JEDEC standards. Multiple packaged chips were characterized with no perceptible difference in performance, indicating a robust design.
Binding Dynamics in Biological Systems. Interaction of MOPC-315 with ^(19)F Labelled Nitrophenyl Haptens

We have studied the dynamics of binding of ^(19)F labelled haptens by mouse plasmacytoma antibody MOPC-315, a protein which shows specificity for nitrophenyl haptens. The off-rates for the dissociation of hapten from MOPC-315 proteins (7S, Fab′ and Fv) were determined by the application of several methods including a technique which, in certain cases, allows the direct determination of the rate of exchange of nuclei between magnetically non-equivalent sites without requiring prior knowledge of intrinsic line widths. Used in conjunction with independently determined data on line widths, chemical shifts, and binding affinities, these studies show that the rates for hapten association to, or dissociation from, the intact 7S antibody, the Fab′ fragment, and the Fv fragment of MOPC-315 are essentially the same. They also indicate the presence, probably in the Fv region, of a low affinity (K∼ 10^3M^(−1)) site(s) for hapten binding. The mobility of the hapten combining site decreases as the size of the protein increases. These rate data, which were determined at relatively high protein concentrations (up to 40 mg ml^(−1)), agree with on-rates determined at much lower protein concentrations (≤1 mg ml^(−1)); we therefore conclude that protein aggregation, if it does occur, does not significantly affect binding in these systems.
The level of omnichannel use in Polish MSMEs

Nowadays, trade is shifting mainly to virtual reality. Increasingly more customers, using various types of mobile devices, such as computers, smartphones, tablets, look for products and services in online stores, counting on fast, convenient and efficient fulfilment of the order. In order to meet the customers’ requirements, trade enterprises may implement omnichannel strategy as a way to streamline the entire sales and distribution system of goods from the store to the customer, ensuring the possibility of continuous monitoring of the transaction. The paper examines the development of omnichannel strategy by the Polish small and medium enterprises. The underlying assumption of the paper is to identify to what extent the Polish companies concentrate on omnichannel strategy in the functioning of their business. The discussion is based on the results of the study obtained from the CAWI survey, CATI survey, and the in-depth interview conducted among the group of Polish MSMEs in Silesian Voivodeship.
PureEdgeSim: A simulation framework for performance evaluation of cloud, edge and mist computing environments

Edge and Mist Computing are two emerging paradigms that aim to reduce latency and the Cloud workload by bringing its applications close to the Internet of Things (IoT) devices. In such complex environments, simulation makes it possible to evaluate the adopted strategies before their deployment on a real distributed system. However, despite the research advancement in this area, simulation tools are lacking, especially in the case of Mist Computing [11], where heterogeneous and constrained devices cooperate and share their resources. Motivated by this, in this paper, we present PureEdgeSim, a simulation toolkit that enables the simulation of Cloud, Edge, and Mist Computing environments and the evaluation of the adopted resources management strategies, in terms of delays, energy consumption, resources utilization, and tasks success rate. To show its capabilities, we introduce a case study, in which we evaluate the different architectures, orchestration algorithms, and the impact of offloading criteria. The simulation results show the effectiveness of PureEdgeSim in modeling such complex and dynamic environments.
INORGANIC SYNTHESIS AND INDUSTRIAL INORGANIC CHEMISTRY Production of Foamed Materials from Synthesized Silicate Glasses

Possibility of obtaining materials with cellular structure directly in syntheses of silicate glasses was demonstrated. It was confi rmed that water released in glass formation can serve as a gas-producing agent. The necessity for a deep extent of the topochemical glass-formation process was revealed. A resource-saving solution was suggested for synthesis of foamed glasses, based on the replacement of a part of glass being synthesized from hydrosilicates with a fi nished sodium-calcium glass. DOI: 10.1134/S1070427213070013 Cellular silicate glasses, or foamed glass, are primarily known for their heat-insulating properties. However, this material is made unique by the set of properties, unreachable in combination for none of the known heat insulators. These are, in addition to the low heat conductivity and density, also full incombustibility, high strength, and absence of any corrosion or disintegration in the course of time. Unfortunately, Russia presently has no industrial manufacture of foamed glass, despite that the material had been produced before the early 1990s at several plants and thorough studies of the given technology were performed. At that time, foamed glass was predominantly fabricated from a specially melted sulfate glass, which markedly narrowed the range of raw material resources and raised the cost of fi nished products. The gas-formation process was based on the reduction of sulfur(IV) contained in the glass with carbon commonly added to the glass in the grinding stage. The above-mentioned monograph by B.K. Demidovich mostly presented results of studies concerned with just these glasses. The author confi rms by thermodynamic calculations that “the reaction of Na2SO4 reduction by solid carbon . in a silicate glass in the water vapor atmosphere has the following form: Na2SO4 + 2C + SiO2 + H2O=Na2SiO3 + 2CO2 + H2S, It should be noted that, in accordance with the calculations presented by B.K. Demidovich, the most probable pathway for reduction of sulfates in the absence or at a small amount of water vapor, is via formation of sulfi des: Na2SO4 + 2C=Na2S + 2CO2. Of a similar opinion is F. Shill [3], who gives the following scheme: SO3 glass + 2C → S2 glass + CO + CO2. A fundamental circumstance in all of these cases is that the oxidized sulfur S6 whose amount is subject to regulations in ordinary silicate glass and is no problem for a consumer is converted to a reduced sulfur S–2 in fabrication of a foamed glass. In this case, the latter is present in the structure of the fi nished material either as a gas, hydrogen sulfi de, or as compounds, sulfi des, in the solid phase of the material. When interacting with water vapor always contained in air, the sulfi des are hydrolyzed with still the same hydrogen sulfi de released
Linear Expansion and Durability of a Composite Boards (MDF Laminated Using Three Selected Wood Veneers) against Drywood Termites

1) This research was conducted to investigate the linear expansion and resistance properties of a composite board (com-ply). This board was made of medium-density fiberboard (MDF) laminated using avocado (Persea americana), mahogany (Swietenia mahogani), and pine (Pinus merkusii) veneers. These three types of veneers were laminated on both surfaces of the MDF using adhesives, namely, epoxy and isocyanate. Glue (250 g・m−2) was spread on the surface, followed by cold press for 3 h with an applied pressure of 15 kg・cm−2. The research result revealed that com-ply exhibited an increased dimensional stability compared with MDF, indicated by reduction in water absorption, thickness swelling, and linear expansion. The com-ply made of the pine veneer and isocyanate adhesive exhibited high density, water absorption, thickness swelling, and screw withdrawal load. The com-ply that exhibited the strongest resistance to drywood termite attacks was the one made of the mahogany veneer and isocyanate adhesive. Moreover, the com-ply that exhibited the biggest weight loss (3.6 %) was made of the pine veneer and epoxy adhesive. The results of this research may facilitate in manufacturing com-ply using the selected veneer and adhesive without the application of hot press.
Spectrophotometric estimation of total tannins in some ayurvedic eye drops

Ayurvedic eye drops preparation contains aqueous extracts of different herbs. Ethnobotanical survey shows that plants used in Ayurvedic eye drops formulation are rich source of tannin and tannin like compounds. Antioxidant and antimicrobial properties of ayurvedic eye drops are attributed to the presence of tannins and tannin like compounds. Therefore in the present study an attempt has been made to determine the tannin content in some ayurvedic eye drops, by using Folin-Denis method. A blue colored complex is formed by using phosphotungustomolybdic acid. Estimation was done on UV/Vis spectrophotometer. The tannin content of all the three brands was found to be 420, 918 and 270.49 µg/ml. The results obtained are reproducible with coefficient of variation less than 1.0% . Hence the present approach can be used as one of the parameters for the standardization of ayurvedic eye drop preparations.
Biblioteki akademickie w nocy – cz. 1 – doświadczenia zagraniczne

Thesis/Objective – availability of all services twenty four hours a day and seven days a week usually is abbreviated as 24/7. with regard to library services it means not only virtual, remote access to library resources and services but also permanent, physical access to library reading rooms and collections stored there. However, there are not many libraries in the world open round the clock. On the other hand there is an emerging tendency to extend library hours, in particular academic libraries do that in response to students’ needs. The aim of this article is to present foreign academic library experience as regards night library services. Research methods – The author analyzed literature on library organization and management, focusing on the publications discussing the results of research on the use of libraries at night. In addition regular and non-standard academic library hours displayed on the library websites were analyzed. Results and conclusions – Studies on user needs and night library user counters definitely show that extended library hours are justified. The decreasing number of library users during late night hours is obvious and expected. However, the number of users interested in onsite access to academic library collections around midnight (or even later) usually is so high that justifies the decision to extend library hours in selected periods of an academic year.
Upper limb replantation: Surgical strategy and the prophylaxis of acute renal failure in ischemia reperfusion injury: A report of two cases

Introduction. The arm replantation is extremely rare and challenging procedure. The recognised risk is myoglobinuria and ischemia reperfusion induced renal failure. Case report. Two patients aged 24 and 46-years were admitted after traumatic arm amputation. Ischemia time was two hours and six hours. Postoperative intensive care treatment with assisted ventilation, sedation and obtaining sufficient urine output prevents myoglobin induced renal injury. In case where ischemia time was shorter, there was only one delayed reconstruction of skin defects after fasciotomy, but in the case where ischemia lasted longer, patient had two secondary look procedures with acceptable definitive results. Conclusion. Arm replantation is safe procedure even in cases with longer ischemia time. Postoperative control of urine output and correction of acidosis, preventing myoglobin induced tubular injury is crucial for stable postoperative recovery.
Discovery of RSV-Induced BRD4 Protein Interactions Using Native Immunoprecipitation and Parallel Accumulation—Serial Fragmentation (PASEF) Mass Spectrometry

Respiratory Syncytial Virus (RSV) causes severe inflammation and airway pathology in children and the elderly by infecting the epithelial cells of the upper and lower respiratory tract. RSV replication is sensed by intracellular pattern recognition receptors upstream of the IRF and NF-κB transcription factors. These proteins coordinate an innate inflammatory response via Bromodomain-containing protein 4 (BRD4), a protein that functions as a scaffold for unknown transcriptional regulators. To better understand the pleiotropic regulatory function of BRD4, we examine the BRD4 interactome and identify how RSV infection dynamically alters it. To accomplish these goals, we leverage native immunoprecipitation and Parallel Accumulation—Serial Fragmentation (PASEF) mass spectrometry to examine BRD4 complexes isolated from human alveolar epithelial cells in the absence or presence of RSV infection. In addition, we explore the role of BRD4’s acetyl-lysine binding bromodomains in mediating these interactions by using a highly selective competitive bromodomain inhibitor. We identify 101 proteins that are significantly enriched in the BRD4 complex and are responsive to both RSV-infection and BRD4 inhibition. These proteins are highly enriched in transcription factors and transcriptional coactivators. Among them, we identify members of the AP1 transcription factor complex, a complex important in innate signaling and cell stress responses. We independently confirm the BRD4/AP1 interaction in primary human small airway epithelial cells. We conclude that BRD4 recruits multiple transcription factors during RSV infection in a manner dependent on acetyl-lysine binding domain interactions. This data suggests that BRD4 recruits transcription factors to target its RNA processing complex to regulate gene expression in innate immunity and inflammation.
Nature of the power-dependent ultrafast relaxation process of photoexcited charge carriers in II-VI semiconductor quantum dots: Effects of particle size, surface, and electronic structure

The power-dependent relaxation dynamics of photoexcited charge carriers in a number of II-VI semiconductor quantum dots have been studied using femtosecond laser spectroscopy. The dynamics are obtained via excitation of the quantum dots with high power 390 nm pulses of 150 fs duration, and probing of the photoexcited species by monitoring the change in absorption at 790 nm as a function of time. Particles with vastly differing surfaces, sizes, electronic structures, and solvents all show a fast 1.5–4 picosecond decay component which grows in with power, a 17 ps (CdSe) or 50 ps (CdS and Cd0.5Zn0.5S) decay component, and some transient absorption persisting beyond 600 ps. The power-dependent component for CdSe quantum dots in glass has a 1.5 ps decay time constant, while for the liquid dispersed CdS and Cd0.5Zn0. 5S quantum dots it has 2–4 ps decay time constants. This variation in the time constant is due to its power dependence, the time constant decreases with increasing power. It is also shown that the p.
A Multiport Modular DC–DC Converter With Low-Loss Series LC Power Balancing Unit for MVDC Interface of Distributed Photovoltaics

An input-independent and output-series modular dc–dc converter with multiple input ports and high voltage conversion ratio can apply well to medium-voltage dc interface of distributed photovoltaics (PV). However, PV power mismatch will result in output voltage imbalance of the submodules (SMs), which is contrary to the standardized multimodule design. In this article, a multiport modular dc–dc converter with low-loss series LC power balancing unit (PBU) is proposed to address this problem. An isolated dc–dc converter is employed as the SM, which consists of full-bridge (FB) circuit on the PV side and half-bridge (HB) circuit on the grid side. Independent maximum power point tracking can be realized by controlling the phase shift between the FB and the HB, while voltage balancing (or power balancing) of SMs can be achieved by regulating the phase shift between adjacent HBs. Only one inductor and one capacitor are used in the PBU and all the switches of SM turn on with zero-voltage switching, which contributes to the low-cost and low-loss characteristic of the converter. Simulations and experiments are carried out to verify the validity of the theory.
Crystal Structure and Electrical Properties of the Pyrochlore Ruthenate Bi2-xYxRu2O7

The bismuth yttrium pyrochlore ruthenates Bi2-xYxRu2O7 have been synthesized and characterized by X-ray Rietveld structure refinement and electrical conductivity measurement. Room temperature resistivities increase with x, and a change from metallic to semiconducting behavior is observed between x = 1.2 and 1.4. The distortion of the RuO6 octahedra and the bend in the RuO6 zig-zag chains increase with x. The transition from metallic to semiconducting state is correlated with the variation of the Ru-O-Ru angle from 139° at x = 0.0 to 129° at x = 2.0. The Ru-O bond length in the RuO6 octahedra increases in the interval 0 ≤ x ≤ 1.2. This variation is understood to result from the contribution of Bi orbitals to the conduction hand; in the metallic regime, 0 ≤ x ≤ 1.2, the electron transfer leads to short Ru-O bond length, whereas in the nonmetallic stale there is little Ru-O bond length variation because there is no contribution of the Bi electrons to the Ru 4d state.
