Modeling of microwave induced deposition plasmas

We present a two-dimensional plasma model for a coaxial microwave discharge. The microwave energy at driving frequency of 2.45 GHz is fed into a coaxial configuration in which the plasma acts as an outer conductor in such a way that a spatially extended surface wave is created. This geometry permits large surface treatment, especially if a set of such coaxial lines are used. The 2D model describes the plasma as a two-temperature non-chemical equilibrium fluid sustained by electromagnetic surface waves. We present results for argon as a working gas. Discussed is the importance of wave-plasma power coupling and electron heat transport. The radial localization of electron density in coaxial plasma waveguide is observed and compared to experimental results. Moreover, a parameter study allows to investigate the dependency of radial contraction of the electron density as function of pressure in the range of 2 to 8 mbar, and also the dependency of electron density on the power input in the range of 120 to 1200 W. In order to verify the model, the modeling results are compared with experimental results for the electron density and temperature and a good agreement is found. 3.
Lobanovite, K2Na(Fe2+4Mg2Na)Ti2(Si4O12)2O2(OH)4, a new mineral of the astrophyllite supergroup and its relation to magnesioastrophyllite

Abstract Lobanovite, K2Na(Fe2+4 Mg2Na)Ti2(Si4O12)2O2(OH)4, is a new mineral of the astrophyllite supergroup from Mt. Yukspor, the Khibiny alkaline massif, Kola Peninsula Russia. It has been known previously under the following names: monoclinic astrophyllite, magnesium astrophyllite, magnesiumastrophyllite and magnesioastrophyllite but has never been formally proposed and approved as a valid mineral species by the Commission on newMinerals, Nomenclature and Classification of the International Mineralogical Association. It has now been revalidated and named lobanovite after Dr. Konstantin V. Lobanov, a prominent Russian ore geologist who worked in the Kola Peninsula for more than forty years (Nomenclature voting proposal 15-B). Lobanovite has been described from pegmatitic cavities on Mt. Yukspor where it occurs as elongated bladed crystals, up to 0.04 mm wide and 0.2 mm long, with a straw yellow to orange colour. Associated minerals are shcherbakovite, lamprophyllite, delindeite, wadeite, umbite and kostylevite. Lobanovite is biaxial (-) with refractive indices (λ = 589 nm) α = 1.658, βcalc. = 1.687, γ = 1.710; 2Vmeas. = 81.5-83°. Lobanovite is monoclinic, space group C2/m, a = 5.3327(2), b=23.1535(9), c = 10.3775(4) Å, β = 99.615(1)°, V = 1263.3 (1) Å3, Z = 2. The six strongest reflections in the powder X-ray diffraction data [d (Å), I, (hkl)] are: 3.38, 100, (003); 2.548, 90, (063); 10.1, 80, (001); 3.80, 60, (042,131); 3.079, 50, (132,062); 2.763, 90, (1̅71). The chemical composition of lobanovitewas determined by electron-microprobe analysis and the empirical formula (K1.97Ba0.01)Σ1. 98(Na0.65Ca0.14)Σ0. 79(Fe2+3.18Mg2.02Na1.00Mn0.72)Σ6. 92(Ti1.99 Nb0.06)Σ2. 05[(Si8.01Al0.06)Σ8. 07O24]O2(OH)4.03F0. 19 was calculated on the basis of 30.2(O + OH + F) anions, with H2O calculated from structure refinement, Dcalc. = 3.161 g cm-3. In the structure of lobanovite, the main structural unit is the HOH block, which consists of one close-packed O (Octahedral) and two H (Heteropolyhedral) sheets. The M(1-4) octahedra form the O sheet and the T4O12 astrophyllite ribbons and [5]-coordinated Ti-dominant D polyhedra link through common vertices to form the H sheet. The HOH blocks repeat along [001], and K and Na atoms occur at the interstitial A and B sites. The simplified and end-member formulae of lobanovite are K2Na [(Fe2+,Mn)4Mg2Na]Ti2(Si4O12)2O2(OH)4 and K2Na(Fe2+4Mg2Na)Ti2(Si4O12)2O2(OH)4, respectively.
EFFECT OF ADDING CINNAMON, GARLIC AND JUNIPER ESSENTIAL OILS ON PRODUCTIVE PERFORMANCE OF NEW-ZEALAND WHITE RABBITS

A total number of 72 male New-Zealand White (NZW) rabbits after weaning were used to study the effect of cinnamon, garlic and juniper essential oils (EOS) as feed additives at level of 0.5 ml/kg diet on rabbit’s nutrients digestibility, growth performance,caecum microorganism's count,blood serum constituents and carcass characteristics. Rabbits were classified into 4 equal groups divided into 3 replicates, 6 rabbits each, till age 8 weeks. The 1st group received the basal diet (G1). The other three groups (G2nd–G4th) received the basal diet with cinnamon, garlic and juniper (EOS) at 0.5ml/kg diet v/w, respectively. Juniper EO significantly decreased the CP digestibility by 5.5% and the CF digestibility by 3.3% compared to the control group. Garlic EO significantly increased the total body weight by 12.4% and the average body weight gain by 12.4%, compared to the control group. Adding cinnamon and juniper EOs to diets led to a significant decrease in the total daily dry matter intake compared to the control group. The results also indicated that adding cinnamon, garlic and juniper EOs significantly increased the total bacterial count by 22.2, 70 and 33.3% and the cellulolytic bacteria by 50, 100 and 60%, respectively compared to the control group.Juniper oil significantly increased the levels of serum albumin and improved feed conversion by 29.4% compared to the control group. Cinnamon and juniper oils significantly decreased the serum levels of triglycerides, total cholesterol, GOT and urea, while significantly increase HDL-cholesterol compared to the control group.
Clinical Value of Physical Examination and Electromyography in Acute and Chronic Lumbosacral Radiculopathy

Objective: To investigate the diagnostic accuracy of two physical examinations (straight leg raise [SLR] and Bragard test) and electromyography (EMG) in patients with lumbosacral monoradiculopathy in acute and chronic state on confirmation of different diagnostic criteria (MRI vs MRI and diagnostic selective nerve root block [DSNRB]). Method: We identified 297 participants retrospectively from the departmental database. MRI evidence of L5 or S1 nerve root compression and a positive result in diagnostic SNRB served as reference standards. They were divided into two groups by the symptom duration: lasting more than 12 weeks in the chronic group and less than 12 weeks in the acute group. The diagnostic value of clinical tests and EMG were compared. Results: The clinical tests (SLR and Bragard test) done in acute stage on detection by MRI and DSNRB had the highest sensitivity (68%) compared to the chronic stage (63%), but sensitivity was low (57%) on confirmation of MRI alone. However, there was no significant difference on sensitivity and specificity of EMG regardless of reference standards and symptom duration. Electromyography was a significant predictor of neuropathic abnormalities on both acute (OR, 6.3; 95% CI, 2.4 to 16.7; p ＜ 0.01) and chronic (OR, 6.8; 95% CI, 2.9 to 16.3; p ＜ 0.01). Conclusion: In general, individual physical tests are easy to do and a combination of those tests could be a sensitive indicator of L5 or S1 radiculopathy. Furthermore, the use of provocation tests could provide useful information, especially in proceeding therapeutic selective nerve root block. (Clinical Pain 2020;19:90-96)
602. Do These Labs Really Matter? Searching for the Benefit of Laboratory Monitoring in Outpatient Parenteral Antimicrobial Therapy (OPAT)

Weekly laboratory monitoring is routinely performed for patients treated with Outpatient Parenteral Antimicrobial Therapy (OPAT). However, minimal evidence exists to guide this practice. This was a single-center, retrospective cohort study to assess the value of laboratory monitoring in patients being treated with beta-lactam OPAT. This study included adult patients discharged from University of Utah Health (UUH) between January 1, 2018, and July 31, 2019, on beta-lactam OPAT with follow-up care with a UUH Infectious Diseases (ID) Provider. Patients discharged to a skilled nursing facility or long-term acute care hospital, or who received OPAT for a duration less than 7 days, were excluded. The primary aim was to describe how often abnormal laboratory values led to a therapy modification or documented adverse drug reaction (ADR) for patients receiving beta-lactam OPAT. Abnormal laboratory values were defined by consensus criteria for clinical significance (e.g., RIFLE criteria for kidney injury). Therapy modification and ADR occurrence was determined by chart review for UUH ID Provider documentation. A total of 346 patients were included; two hundred seventy-four (79%) had abnormal laboratory values during OPAT. Of these, 12 patients had a modification to their OPAT due to abnormal laboratory values. The most common therapy modification due to abnormal laboratory values was a change of antibiotic (9/12). Two hundred thirteen of 274 patients (78%) with abnormal laboratory values were maintained on their OPAT regimen without a modification. Of the 67 therapy modifications observed, 55 (82%) were due to reasons other than abnormal laboratory results (Table 1). Abnormal laboratory values meeting criteria for clinical significance and possible ADR were observed in 469 instances. Of these, 43 (9%) were considered ADRs by the ID provider (Table 2). Table 1 describes therapy modifications for patients on beta-lactam OPAT Table 2 describes documented ADRs in the presence of abnormal labs for patients on beta-lactam OPAT Weekly laboratory monitoring was associated with therapy modifications and documented ADRs in a small number of patients receiving beta-lactam agents as OPAT. This supports current guideline recommendations for laboratory monitoring, even for beta-lactam agents, which are considered relatively safe. Further investigation into the cost-effectiveness of this approach is warranted. Russell J.

Preliminary Phytochemical Screening, Proximate Analysis, Antioxidant and Antibacterial Activities of an Algal Species of Hydrodictyon Reticulatum

The freshwater algae grow in a wide range of aquatic habitats across the globe and are rich in secondary metabolites. The present study was designed to conduct the phytochemical screening, proximate analysis, antioxidant and antibacterial activities of water net (Hydrodictyon reticulatum), an algal weed from Pakistan. The pure and dried algal mass was crushed into a fine powder and four solvent-based extracts were used for phytochemical screening. The results of preliminary qualitative screening indicated the presence of flavonoids, phenols, quinones, steroids, resins, anthraquinones, glycosides, lignin, proteins, saponins, tannins, reducing sugars, alkaloids, terpenoids, fats, and oils, whereas the quantification results revealed the high quantities of total ash, crude proteins, crude fiber, alkaloids, carotenoids, flavonoids, and chlorophyll a. The studied methanolic extracts with maximum concentration (150 μg/ml) showed significantly (p-value ≤ 0.05) higher antioxidant and antibacterial activities. The IC50 values of the crude methanolic extract of water net were found very close to streptomycin (positive control) against both bacterial pathogenic species of Klebsiella pneumoniae and Staphylococcus aureus. This study concluded that the crude extracts of water net possessed antibacterial activity at par to streptomycin drug, and requires further detailed study for the separation, identification, and testing of the pure phytochemical compound to be used by the nutraceutical and or pharmaceutical industry.
Financial regulations and risk in the context of the global recession

Purpose- The purpose of this paper is to examine the effects of regulations on the risk during the 2008 financial crisis. In other words, , the causes of the 2008 financial crisis are presented and the main reforms made in the field of international banking after the financial crisis and their effects are offered. Methodology- This study is a comparative situation analysis by using the data of Germany, United Kingdom, United States, EU Area and World. Findings- In order to cope with the effects of the crisis, the United States, Europe and other major economies, which constitute the basis of international financial architecture, have started to take measures rapidly. Priority has been given to eliminating the effects of the crisis on financial markets, and measures have been taken to create a new and strong financial architecture and restore financial stability. This study analyzes these measures and their effects on the economy. Conclusion- After extensive arrangements, the banking sector recorded a significant increase in the amount and quality of capital. This success was mostly achieved with capital increases. The same positive situation is true for liquidity. This is seen not only in the improvement of the main liquidity ratios but also in the reduction of the simple ratio between loans and deposits. The obligation to provide bail for the liabilities of banks reduces the possibility that the banks will be supported by the government through bail in a future crisis.
Highly sensitive poisoning-resistant optical carbon dioxide sensors for environmental monitoring

A new optical carbon dioxide sensor for environmental monitoring is presented. It combines a robust and long-term stable sensing material with a compact read-out device. The sensing material relies on a NIR pH indicator immobilized into ethyl cellulose along with a quaternary ammonium base. The perfluorinated polymer Hyflon AD 60 used as a protection layer significantly enhances the long-term and mechanical stability of the sensor foils, as well as the robustness against poisoning gases, e.g. hydrogen sulfide. The sensor can be stored under ambient conditions for more than six weeks, whereas sensors covered with silicone rubber deteriorate within one week under the same conditions. The complete sensor device is applicable after a three-point (re)calibration without a preconditioning step. The carbon dioxide production and consumption of the water plant Egeria densa was measured in the laboratory. Furthermore, results of profiling carbon dioxide measurements during a research cruise on the Baltic Sea at water depths up to 225 m are presented.
Indonesian in Service Teacher’s Production of Directive Speech Acts and Students’ Responses

Teacher uses language as a medium of communication to teach, guide and instruct students in the classroom. This study aims to investigate the English teacher's directives and the students' responses to these directives. This study participants were an English teacher of a junior high school in Indonesia who teaches an eighth-grade class and her students who were chosen purposively. This qualitative case study was collected through observation, and interviews and were then analyzed by following Miles' interactive cyclical model. The results revealed that the teacher mostly produced directive speech acts types of commands and requests rather than suggestions. Commands have been the most commonly used type of directives since the teacher plays a control in the classroom because it is more understandable and familiar for the students. Hence, the students' responses varied, and depended on their response strategies and each personal reason.

Photoabsorption and photoionization cross sections for formaldehyde in the vacuum-ultraviolet energy range

We report a theoretical-experimental investigation on the interaction of vacuum-ultraviolet radiation with formaldehyde (H2CO) in the gas phase. Experimentally, the absolute photoabsorption cross sections and the photoionization quantum yields were measured in the (11.0–21.5) eV range using the double-ion chamber technique. Also, the absolute photoionization and neutral-decay cross sections were derived from these data. In addition, in the same energy region, the dissociation pattern was obtained with a time-of-flight mass spectrometer using the photoelectron-photoion coincidence technique, and the absolute photoionization cross sections were derived for each ionic fragment observed. Moreover, theoretical photoionization cross sections were calculated for the ionization of the four outermost molecular valence orbitals (2b2, 1b1, 5a1, and 1b2) from the threshold to 35 eV. The calculations were performed using the iterative Schwinger variational method to solve the Lippmann-Schwinger equation in the exact s.
