Analyses booléenne et continue de systèmes comportant des boucles de rétroaction. I. Analyse continue des boucles de rétroaction simples
Authors: Richelle Jean 
Published: June 2020

Nous qualifions de simples les boucles de rétroaction dont chaque élément exerce un contrôle direct (positif ou négatif) uniquement sur l'élément de la boucle qui le suit immédiatement et n'est lui-même directement contrôlé que par l'élément qui le précède. Chaque élément exerce cependant un contrôle indirect sur son propre développement ultérieur, via les autres éléments de la boucle. Ce contrôle est positif ou négatif selon la parité du nombre d'interactions négatives dans la boucle ; aussi qualifions-nous de positives les boucles qui comportent un nombre pair d'interactions négatives, de négatives les boucles qui en comportent un nombre impair.
Les boucles positives simples peuvent avoir des états stationnaires multiples, mais un comportement périodique stable ne leur est pas permis. Par contre les boucles négatives, qui, en aucun cas, n'ont des états stationnaires multiples, peuvent présenter un comportement cyclique.

Published: June 2020

Twilight data obtained photographically from a stratospheric balloon platform in the falls of 1980 and 1981 and in the spring of 1982 are presented for blue and red light. They indicate the presence of a dust light absorbing and scattering layer in the mesosphere at altitudes near 60 km with a low scattering albedo (0.1) at 0.44 (im. The optical efficiency of the layer increases more than 10 times when the wavelength of the interacting light changes from 0.65 (im to 0.44 (im. At the zenith and near sunset, the natural 0.44 um extinction optical thickness and the cm2column scattering rate due to this layer are respectively found to be 6.6 x 10-2 and 0.18 mega Rayleigh per À on May 3, 1982 above the south west of France.
The observations are presented in the framework of other data derived from ground, aircraft, balloons and spacecraft observations.
Composition et exportations minérales du tournesol en fonction de la dose alimentaire
Authors: Luyindula Nuanisa 
Published: June 2020

Between the limits of the studied concentrations, the mineral content (meg/ 100 g dry matter) responds linearly to the concentration.
For aerial parts, the variation indexes are highest for nitrogen and potas¬ sium. But for the seeds, this indexes are highest for sulphur, phosphorus, nitrogen and potassium.
The anionic to the cationic ratio (A/C) in seeds increases with the concentration of the solution, but stays invariant in the aerial parts.
The exportation of mineral content are curvilinear with the concentration of the solution : the fonction Homès-Van Schoor gives a very good estimation {y = kCpe-mC). A curvilinear function between mineral content and concentration can also be determined from the fonctions of exportation and yield. The advantage of estimation is not enough to chose the curvilinear function and the linear one is chosen for the facility of the calculation.
Premières tentatives d 'introduction du système métrique en médecine et en pharmacie
Authors: Radoux Lambert , Lecomte Jean 
Published: June 2020

La nécessité de mettre en œuvre un système de mesure simple, cohérent, reposant sur des étalons assurés, utilisable par tous a été comprise par les hommes éclairés qui firent la Révolution française. La construction du système métrique est la conséquence de leur clairvoyance. Ils ont été aussi conscients de l'importance que revêt l'adoption de ce système et des unités décimales par les médecins et les pharmaciens. Le résumé d'un rapport présenté l'an X devant la Société de médecine de Paris par 3 citoyens, et publié dans nos régions le 16 messidor an X (5 juillet 1802), par les soins du ministère de l'Intérieur témoigne des efforts de rationalisation du gouvernement en matière de santé publique. Ils visaient à prévenir les accidents liés à la diversité des poids et mesures utilisés en pharmacie.
Ces efforts n'eurent pas les effets escomptés car ils se sont heurtés aux traditions d'une profession bloquée dans un empirisme et un formalisme outranciers. Il a fallu attendre la transformation de la médecine en une science pour que le recours au système métrique s'impose irréversiblement.
On the linear evolution of the surface of a viscous incompressible fluid
Authors: Cerda Enrique , Tirapegui Enrique 
Published: June 2020

We consider a layer of viscous incompressible fluid on a plate which can be vibrated vertically and we derive an equation which is non local in time for the linear evolution of the deformation of the surface in contact with the atmosphere. The equation is used to study the decay of a deformation of the surface. We characterize an interesting regime of high viscosity where the equation becomes local and we use it to study Faraday's instability. A new scenario is found for low frequency of the forcing.
Key words : viscous fluid, Faraday's instability, lubrication regime.

The collected mosquitoes are inserted into the maintenance cage to identify and ensure that the mosquito is truly Anopheles sp. The test was done by using impregnanted paper malathion 0.8% .Amount of 25 mosquitoes were caught using an aspirator and put into a collector tube which had been coated with 0.8% impregnated paper malathion , while other 25 mosquitoes were put into a green tube and had no insecticide paper. The test results were obtained by counting the knocked down mosquitoes every 15 minutes during 2 hours of insecticide exposure and continued for 24 hours of holding time. The test was repeated for 3 times. The results showed that Anopheles sp. in Kota Lama and Maulafa districts, were resistant to Malathion insecticides 0.8% with the percentage of death mosquitoes (Kota Lama: 4,35-28% ; Maulafa: 8-12,5%)(< 90%). So it has a high level of resistance.
Factors shaping buildings of low energy consumption
Authors: Pawłowski Krzysztof , Nakielska Magdalena 
Published: June 2020

The Directive 2010/31/EU introduces a new building standard (NZEB) in all member states of the European Union from 1.01.2021. In Poland, a low-energy building has been defined. The design, construction and use of such building is a complex process and requires knowledge of many aspects concerning building materials, general construction, building physics, installations, renewable energy systems and architectural design. Implementation of the current technical requirements in this area encompasses examining many parameters of an entire building but also of its external walls and joints. Defining them according to the applicable legal regulations and relevant standards evokes many questions and uncertainties regarding calculation procedures and interpretation of physical aspects. On the basis of conducted calculations and analyses, the authors have started a discussion on calculation methods in this field, proposing changes in legal regulations and calculation procedures.
The paper describes selected factors influencing low-energy buildings: physical parameters of building envelope elements, support of modern ventilation systems, energy performance parameters. The calculation part of the work concerns the analysis of physical parameters of the elements of low-energy building envelope and energy performance parameters of a buildings with consideration of energy saving and thermal insulation criteria. Formation of material systems of external walls and building joints requires taking into account innovative insulation materials and specific parameters of the air inside and outside of a building. The use of professional software for calculations and analyses provides reliable results.
Many coherent factors such as: architecture of a building, structural and material solutions of the external walls and their joints (elements of the building envelope), type and efficiency of the ventilation, central heating and hot water systems, use of renewable energy sources, integral management of the building in the field of energy production help to obtain optimal parameters of energy performance of the building and reduce emissions of CO2 to the atmosphere.

Published: June 2020

Abstract
The frequency-drift-induced self-comparison measurement error was experimentally demonstrated by measuring the frequency difference between two interleaved clock loops with the same systemic parameters in the 87Sr optical lattice clock at the National Time Service Center of China. Combining the experimental and simulated results, this error was precisely determined by the total clock laser frequency drift during the time interval between two adjacent operations of interleaved clock loops.

Assessment of the cytokine profile in patients with allergic rhinitis caused by sensitization to house dust mite
Authors: Yuriev Serhii 
Published: June 2020

The aim of the study was to evaluate the serum cytokine profile of patients with allergic rhinitis (AR) sensitized to house dust mites and to establish their role in the regulation of IgE synthesis
Materials and Methods. The study included 60 patients with AR at the age of 20-60. According to the level of total IgE (IgE>100 kU/L), patients were divided into two groups with an IgE-dependent and IgE-independent form of AR. In the study, the serum levels of IL-2, g-IFN, IL-4, IL-5, IL-13, IL-10 and TGF-b in the blood serum were determined by ELISA.
Results. According to the study, it was found that patients with an IgE-dependent form of AR are characterized by a decrease in the level of Th1 cytokines IL-2 and g-IFN, an increase in the level of Th2 cytokines – IL-4, IL-5 and IL-13 and a decrease in Treg cytokines – IL-10 and TGF- b. At the same time, a significant decrease in the level of inhibiting cytokine IL-10 was established in comparison with the group of patients with an IgE-independent form of AR. For patients with an IgE-independent form, only elevated levels of IL-13 were found. No significant differences were found between other Th1 and Th2 and Treg cytokines.
Conclusions. The study showed that in patients with AR sensitization to house dust mites, IL-13 acts as a key cytokine in the IgE-independent form of AR, which can be important in the future for both predicting and treating AR.

ABSTRACT
Badakhshanite-(Y), ideally Y2Mn4Al(Si2B7BeO24), is a tetrahedral sheet-structure mineral found in the Dorozhny (Road) miarolitic granitic pegmatite within the Kukurt pegmatite field 45 km E of Murghab, Eastern Pamir, Gorno-Badakhshan Autonomous Oblast, Tajikistan. Badakhshanite-(Y) occurs in medium- to coarse-grained non-graphic albite-microcline-quartz pegmatites in close association with smoky quartz, Sc-bearing spessartine, Sc-bearing tusionite, and schorl. It often grows together with Sc-bearing tusionite and occurs as single columnar crystals ranging from 50 to 400 μm in length, as inclusions in spessartine and tourmaline, and rarely as crystals in blebs along boundaries between garnet, tourmaline, and quartz. Badakhshanite-(Y) is yellow brown and has a white streak and a vitreous luster. It is brittle, with a conchoidal fracture, Mohs hardness of 6.5–7, and calculated density of 4.41 g/cm. In thin section it is transparent and pale yellow, non-pleochroic, biaxial (–), with α = 1.805(2), βcalc = 1.827, γ = 1.835(3) (λ = 590 nm); 2V (meas.) = –60(10)°. Dispersion is weak, r &gt; v. Extinction is straight, elongation is negative. FTIR spectra show the absence of (OH) and H2O groups. Chemical analysis by electron microprobe using WDS (6 points), SIMS, and ICP-OES for B and Be gave SiO2 11.96, ThO2 0.12, Sm2O3 0.17, Gd2O3 0.30, Tb2O3 0.10, Dy2O3 0.73, Ho2O3 0.19, Er2O3 1.34, Tm2O3 0.54, Yb2O3 8.82, Lu2O3 2.32, Y2O3 16.60, Sc2O3 1.57, Al2O3 3.06, B2O3 22.06, FeO 0.94, MnO 23.33, CaO 0.58, BeO 2.84, total 97.57 wt.%.The empirical formula based on 24 O apfu is (Y1.21REE0.78Th0.01)Σ2(Mn3.47Y0.34Ca0.11Fe2+0.08)Σ4(Al0.63Sc0.24Fe2+0.06□0.07)Σ1[(Si2.10B6.69Be1.20)Σ9.99O24], where REE = (Yb0.47Lu0.12Dy0.04Er0.07Tm0.03 Ho0.01Gd0.02Sm0.01Tb0.01)Σ0.78. Badakhshanite-(Y) is orthorhombic, space group Pnma, a 12.852(1), b 4.5848(5), c 12.8539(8) Å, V 757.38(7) Å3, Z = 2. The crystal structure was refined to R1 = 4.31% based on 1431 unique [F &gt; 4σF] reflections. In the crystal structure of badakhshanite-(Y), a layer of tetrahedra parallel to (010) is composed of four different tetrahedrally coordinated sites: Si, B(1), B(2), and T (&lt;Si–O&gt; = 1.623 Å, &lt;B(1)–O&gt; = 1.485 Å, &lt;B(2)–O&gt; = 1.479 Å, &lt;T–O&gt; = 1.557 Å), which form four-, five-, and eight-membered rings, having the composition (Si2B7BeO24). Between the sheets of tetrahedra, there are three cation sites: M(1), M(2), and M(3) (&lt;M(1)–O&gt; = 2.346 Å, &lt;M(2)–O&gt; = 2.356 Å, &lt;M(3)–O&gt; = 2.016 Å) occupied by Y(REE), Mn2+(Y, Ca, Fe2+), and Al(Sc), respectively. The M(1,2) sites ideally give Y2Mn4apfu; the M(3) site ideally gives Al apfu. Badakhshanite-(Y) is an Al- and Be-analogue of perettiite-(Y).

Published: June 2020

The purpose of this study were to know the role of calculation cost of goods manufactured and determination of the selling price of shoes in the Heriyanto’s shoes MSME. To knowing the extent of differences in determination the cost of goods manufactured by using the company method and the full costing approach and compare the selling price according to the company's method with using the Cost Plus Pricing.
The type of research used is qualitative research. The analytical method used in this study is qualitative descriptive analysis. The data used in this study are primary data. Data were obtained directly through observation and interviews with the Heriyanto’s shoes MSME and data in the form of information on production costs such as raw material costs, labor costs, and factory overhead costs MSME during December 2018. While for secondary data. Data were obtained from intermediary media such as books or literature, journals related to the title of the research, and can also be via the internet. The results of the study it can be concluded that the cost of goods manufactured calculation according Heriyanto’s MSME is lower than the cost of goods manufactured calculation using the full costing method. The cost of goods manufactured according heriyanto’s MSME is Rp. 15.675/pair or Rp. 313.492/score (Hamer Material) and Rp. 14.600/pair or Rp. 291.992/score (Kavaro Material). While the cost of goods manufactured used the full costing method, which is Rp. 16.310/pair or Rp. 326.201/score (Hamer Material) and Rp. 15.235/pair or Rp. 304.701/score (Kavaro Material). This is caused factory overhead costs that are not calculate by Heriyanto’s MSME such as electricity costs, gas costs, maintenance costs for machinery and factory vehicles, and depreciation costs.
Determination of selling price must be appropriately because the determination of selling prices that are too high will result in difficulty competition with similar products while the determination of selling prices too low will result in reduced income generated by Heriyanto’s MSME. The difference in determination the cost of good manufactured will affect the Heriyanto’s MSME in determining the selling price, because the cost of goods manufactured is the main element in determination selling price. Calculation of selling prices according Heriyanto’s MSME is Rp. 18.026/pair or Rp. 360.516/score (Hamer Material) and Rp. 16.790/pair or Rp. 335.791/score (Kavaro material). While the selling price used the Cost Plus Pricing method which is Rp. 18.814/pair or Rp. 376.281/score (Hamer Material) and Rp. 17.578/pair or Rp. 351.556/score (Kavaro material).
