Anopheles darlingi Root and Anopheles aquasalis Curry are the main vectors of malaria that occur in the State of Maranhão. Entomological surveys based on the behavior and infectivity of these vectors are important for the elaboration of disease control strategies. The objectives of this work were to study the behavioral patterns of mosquitoes, determining population and hematophagic peaks, dietary preferences, infectivity rate and characterization of breeding sites in two municipalities in the State of Maranhão: Buriticupu and São José of Ribamar. Larvae and pupae were collected in breeding sites and adult females in home environments. Mosquito behavior, their dietary preferences and Plasmodium spp infection rates were analyzed. The vegetation and physicochemical patterns in the breeding sites found are in agreement with those described for species from the Amazon region and the Brazilian Atlantic coast. Anopheles darlingi was the most prevalent mosquito in Buriticupu breeding and home environments. This species was found mainly fed on human blood and naturally infected with Plasmodium vivax Grassi & Feletti and Plasmodium falciparum Welch. Anopheles aquasalis was more frequent in breeding sites in São José de Ribamar, as well as in home environments, whose specimens were mainly fed with human and bird blood. The main peaks of mosquito occurrence in Buriticupu were between 6 pm to 9 pm and in São José de Ribamar we did not record a definite peak. In the first municipality A. darlingi showed dominance over Anopheles albitarsis Lynch Arribálzaga s.l., Anopheles oswaldoi Peryassú, Anopheles nuneztovari Gabaldón and Anopheles evansae Brèthes,, besides presenting a correlation with rainfall. In the second municipality, A. aquasalis was dominant over A. albitarsis s.l. and there was a correlation between these two species and the rainy season. We conclude that the collected data contribute to elucidate the dynamics of malaria transmission in the region and guide the control actions directed to the elimination of the disease in the country.

The diode laser bar was beam shaped with a tilted cylindrical lens array to twist the slow axis of individual emitters by 90 deg, and then the slow axis was collimated with a single cylindrical lens. From the simulation, 20 laser diode bars with the same wavelength formed a diode laser optical stack with an output power of more than 3.5 kW, a beam spot of

Then, three laser diode optical stacks with different wavelengths were wavelength-multiplexed to obtain an output power of more than 10 kW. Finally, the diode laser optical stack was transformed by simple cylindrical lenses to form a line shape spot with a working distance longer than 250 mm. Our diode laser design is much simpler than previous devices with similar output power and can find various applications such as high-speed laser cladding.

A temporal resolution of 42 ps and a dark count rate of 500 Hz were achieved, limited by the SPAD and ambient light leakage. It allowed for detection of two targets separated by only a few millimeters. This technique is easily extendable to longer wavelengths, limited primarily by the nonlinear crystal transparency.

Published: February 2020

ABSTRACT
A 37-year-old man underwent screening examinations, and a pale-colored submucosal tumor was detected on gastric cardia. Endosonography showed a 15-mm cyst with hypoechoic nodules in the muscularis propria, and endoscopic ultrasound-guided fine-needle aspiration obtained mucinous fluid with atypical spindle cells positive for c-kit, indicating a gastrointestinal stromal tumor. Surgical resection was recommended, but he initially agreed to surveillance. After becoming larger for 8 years, partial gastrectomy was performed for the 22 × 22 × 15-mm capsulized lesion. Surprisingly, its histology was gastric duplication cyst without gastrointestinal stromal tumor. Gastric duplication cyst is a rare entity with the possibility of malignant complications, but careful assessment of endoscopic ultrasound-guided fine-needle aspiration might also be required.

Abstract
The aim of the study was to assess the selected physical characteristics of the briquettes of English ryegrass waste biomass and its mixtures with waste components from the agri-food industry: pea husks and oat middlings. The raw materials used for the tests are characterized by high calorific value and low ash content. Among the tested raw materials, the most favorable values were recorded for oat middlings in this respect. The produced briquettes were characterized by high volumetric density and very diverse mechanical durability. At the same time, the results of the tests on the mechanical durability of briquettes indicated that the use of components of ryegrass mixtures selected for testing brought unsatisfactory results, as compared to other analyzed physical and energy features.

Published: February 2020

Abstract
The paper presents a study on the control of the canned fish seaming with the so-called double seam and statistical analysis of correctness of seaming. The use of standard control charts enabled observation and intervention in case irrelevant parameters occur to keep the stability of the process. Based on the analysis made in Statistica program, a moment could have been captured when a machine had to be regulated in case the value of parameters of the double seam decreased and it had to be concluded unanimously when the most important seaming tools (rolls) should be replaced. A problem that had been solved consists mainly in ensuring the stability of the process during constant monitoring of the seaming process of the canned food.

Abstract
For seed production of sugar and fodder beet, the creation of machines and working bodies for planting root crops on testes and pollinators is of current importance. It was found out that the seed-and-water production was spreading with the use of “schteklings” [sugar beet roots]. In the countries with minus temperatures between the vegetation seasons it is necessary to dig out beets and plant them again at the beginning of the vegetation season. Advantages and disadvantages of machines and apparatus for disembarking the schteklings were determined. Under the conditions of applicability, we chose a design scheme and a type of landing gear. With the use of mathematical expressions and standards for the labor intensity of the operator of the above machine, the optimal parameters of its planting apparatus were determined. It was determined that the work of the operator of the schteklings planting machine’s stem will meet the safety standards for the intensity of labor if the planting unit of this machine is a rotor-type. It should be equipped with planting cones and a charging device, a conveyor type. The number of holders of landing cones should be 6-8 pieces, and the radius of the rotor is within the range of 0.344 ... 0.382 m. Such a scheme, type and parameters of the landing gear will allow operators to work at the speed of the planter of up to 1.2 m·s−1.

Published: February 2020

AbstractThe modern agriculture model is a model based on the principles of sustainable development, i.e. protecting the environment and the cultural landscape on the one hand, and on the other, ensuring adequate income for residents. It is based on three orders: ecological, social and economic. This paper attempts to use cluster analysis to assess the economic and ecological sustainability of organic farms. It also indicates the factors that statistically influenced the assessment of a farm as sustainable, or not. The first part of the work is dedicated to the characteristics of the problem and the methodology of research and analysis. The second part contains the results of the research and discusses them.
The generalized complexity of linear Boolean functions
Authors: Redkin Nikolay P. 
Published: February 2020

AbstractWe study generalized (in terms of bases) complexity of implementation of linear Boolean functions by Boolean circuits in arbitrary functionally complete bases; the complexity of a circuit is defined as the number of gates. Let L*(n) be the minimal number of gates sufficient for implementation of an arbitrary linear Boolean function of n variables in an arbitrary functionally complete basis. We show that L*(0) = L*(1) = 3 and L*(n) = 7(n – 1) for any natural n ≥ 2.
Well-posedness of backward stochastic partial differential equations with Lyapunov condition
Authors: Liu Wei , Zhu Rongchan 
Published: February 2020

Abstract
In this paper we show the existence and uniqueness of strong solutions for a large class of backward SPDEs, where the coefficients satisfy a specific type Lyapunov condition instead of the classical coercivity condition. Moreover, based on the generalized variational framework, we also use the local monotonicity condition
to replace the standard monotonicity condition, which is applicable to various quasilinear and semilinear BSPDE models.

Authors: Rais Andreas , Pretzsch Hans , van de Kuilen Jan-Willem G. 
Published: February 2020

Abstract
In Central Europe, European beech (Fagus sylvatica L.) is the most frequently occurring hardwood species. An efficient grading method has the potential to promote its utilisation as construction material. Wood density, eigenfrequency and length were measured in 99 European beech logs for calculating the dynamic modulus of elasticity (MOEdyn
) obtained by longitudinal vibration (resonance). In addition, the log taper was measured. Of those logs, 867 boards were cut using a bandsaw. The MOEdyn
in green condition was determined on 505 of the boards and the MOEdyn
in dry conditions was determined on all of them. The r2 value between the MOEdyn
of a log and the mean of MOEdyn
of its boards was 0.72 in the wet condition. The MOEdyn,12%
of boards significantly increased by 88 N mm−2 for each centimetre away from the pith. The negative effect of log taper on MOEdyn
of boards was barely significant (P-value = 0.050). The MOEdyn,12%
was highly dependent on the MOEdyn,wet
(r2 = 0.83) and was 17% higher than the MOEdyn,wet
. The mechanical properties of European beech timber exceed those of European softwood species. However, the relationships regarding MOEdyn
between different grading levels in the processing chain appear to be similar to those of softwoods.
Is it really just a joke? Gender differences in perceptions of sexist humor
Authors: Lawless Tiffany J. , O’Dea Conor J. , Miller Stuart S. , Saucier Donald A. 
Published: February 2020

AbstractBenign violation theory suggests humor mocking normative values is funny if the humor is non-threatening. Research suggests sexism toward women (versus men) is particularly threatening due to inequalities in social power. In Study 1, we examined whether men and women differ in how amused and offended they were by sexist humor. We predicted men would perceive sexist humor as more funny and less offensive than women would. In Study 2, we examined whether perceptions of threat were related to perceptions of sexist jokes. We predicted women would perceive more threat than men from sexist humor, which would lead to lower amusement and greater perceived offensiveness. Across both studies, jokes targeting women were perceived to be less funny, more offensive, and more sexist than jokes targeting men. Additionally, greater perceptions of threat were related to greater perceptions of jokes as offensive and sexist. However, women were not more threatened than men by sexist jokes. While these findings were not entirely consistent with our hypotheses, our findings suggest disparagement humor targeting lower-status groups is perceived more negatively than disparagement humor targeting higher-status groups and these perceptions may be inextricably rooted in threat posed to lower-status groups.
Re-imaging Clinical Education: The Interdependence of the Self-Regulated Clinical Teacher and Nursing Student
Authors: Filice Sandra , Tregunno Deborah , Edge Dana , Egan Rylan 
Published: February 2020

Abstract
The interdependence of student learning strategies and teacher’s pedagogical practices is critical to clinical practice learning. While research demonstrates that formative assessment feedback is important for student learning, clinical teachers do not necessarily have the competencies to provide effective feedback to support students’ self-regulated learning (SRL). An examination of clinical education through SRL lenses articulates two roles for clinical teachers in nursing clinical education: self-regulated learner and self-regulated teacher. Teachers as self-regulated learners are practice-content experts and must also learn how to explicitly help students become self-regulated learners. The latter is the self-regulated teacher role, and a self-regulated teacher is an effective clinical teacher. Minimal research addresses the ways in which clinical teachers’ effectiveness could be improved if they took on a self-regulated teacher role. A model of SRL and teaching in clinical practice education is presented and its potential to enhance clinical teacher effectiveness and student SRL articulated.
Linear least squares method in nonlinear parametric inverse problems
Authors: Frumin Leonid L. 
Published: February 2020

Abstract
A generalization of the linear least squares method to a
wide class of parametric nonlinear inverse problems is presented.
The approach is based on the consideration of the operator
equations, with the selected function of parameters as the
solution. The generalization is based on the two mandatory
conditions: the operator equations are linear for the estimated
parameters and the operators have discrete approximations. Not
requiring use of iterations, this approach is well suited for
hardware implementation and also for constructing the first
approximation for the nonlinear least squares method. The examples of
parametric problems, including the problem of estimation of parameters
of some higher transcendental functions, are presented.

Abstract
Recently, Nair and Roy (2017) considered a linear regularization method for a parameter identification problem in an elliptic PDE.
In this paper, we consider similar procedure for identifying the diffusion coefficient in the heat equation, modifying the Sobolev spaces involved appropriately.
We derive error estimates under appropriate conditions and also consider the finite-dimensional realization of the method, which is essential for practical application.
In the analysis of finite-dimensional realization, we give a procedure to obtain finite-dimensional subspaces of an infinite-dimensional Hilbert space

Evaluation of Atmospheric Detrimental Effects on Free Space Optical Communication System for Delhi Weather
Authors: Srivastava Disha , Kaur Gurjit , Singh Garima , Singh Prabhjot 
Published: February 2020

Abstract
Free Space Optical (FSO) communication systems are gaining popularity due to its tremendous speed, advanced capacity, cost effectiveness, secure and easy to deploy wireless networks. This technology has proven an effective choice for last mile applications and hard to reach areas where deployment of optical fibre links is not feasible. But FSO link is highly weather dependent and as signal passes through the atmospheric channel, the main impairments are the atmospheric turbulence, which induce fading and deteriorate the system performance. Delhi has a great potential for FSO communication because of its clear skies. Since there is no analysis for weather condition found in Delhi, this work provides analysis of typical Delhi weather condition ranging from heavy to light rain, fog and clear sky. The performance of FSO link is analysed in terms of attenuation and link length margin under different weather condition. The results are concluded to identify which atmospheric condition influences more on FSO link performance.
The effect of placental elasticity on intraoperative bleeding in pregnant women with previous cesarean section

Published: February 2020

AbstractBackgroundWe aimed to evaluate the efficiency of placental elasticity in predicting the amount of intraoperative bleeding via real-time tissue elastography technique.MethodsPregnant women in the third trimester of pregnancy who had planned delivery via cesarean section due to the recurrent cesareans were enrolled in the research (n = 78). Elastographic measurements of placental tissues of all cases were carried out by real-time elastographic ultrasonography. It is a tissue elastography software (Esaote MyLabSeven) that uses a 8-1-MHz multifrequency AC2541 Probe.ResultsA significant relationship was found between placental elasticity and intraoperative bleeding. There was a significant correlation between alterations in the preoperative and postoperative hemoglobin (Hb) and hematocrit (Hct) levels and placental strain ratio (SR) (P < 0.001, r: 0.831; P < 0.001, r: 0.733, respectively).ConclusionThese findings may reflect an alteration at the tissue elasticity level. We hope that the use of real-time elastographic ultrasonography technique may give an idea about the amount of bleeding during the cesarean section.

Published: February 2020

AbstractBackgroundThis study describes developmental and service transitions during a 3-year period among young people with cerebral palsy (CP) as measured by the Rotterdam Transition Profile (RTP) and evaluates the test-retest reliability of the RTP. The RTP is a questionnaire developed to classify phases of transition across nine participation domains.MethodsA three-step design was applied: Step I consisted of a translation and test-retest reliability study of the RTP, Step II was a comparison of independence between youth with and without CP and Step III was a follow-up survey of youth with CP describing changes of independence after a 3-year transition period. A sample of 103 typically developing youth were recruited for Steps I and II, and a population-based sample of 76 (response rate = 59%) youth with CP (males = 40) from South-Eastern Norway aged 16–17 years were recruited for Steps II and III. The subtypes of CP were classified as spastic unilateral (n = 30), spastic bilateral (n = 37), dyskinetic (n = 8) and ataxic (n = 1) CP. The levels of gross motor function followed the categories of the Gross Motor Function Classification System (GMFCS) as level I (n = 30), level II (n = 17), level III (n = 6), level IV (n = 8) and level V (n = 15).ResultsTwenty-six participants had epilepsy and 13 had gastrostomy. Forty-four of the youth with CP (response rate = 58%) responded to the 3-year follow-up survey in Step III. The test-retest study of the RTP showed excellent reliability (Kw 0.76–0.93). At baseline (Step II), the reference group was significantly more independent than the youth with CP in all the participation domains. At the 3-year follow-up (Step III), the levels of independence had increased significantly for all the participation domains in the youth with CP except for transportation and leisure. Despite increased independence during the transition period regarding health services, only 25% independently formulated their own care needs or applied for services and assistance at 19–20 years of age. Youth who responded to the RTP by a caregiver proxy more often had a diagnosis of epilepsy and/or gastrostomy and higher GMFCS levels. These individuals were significantly less independent than those who self-reported, both at baseline and at follow-up.ConclusionsIn conclusion, the excellent test-retest results support the use of the RTP as a tool for classifying phases of transition among youth with CP. The youth with CP were significantly less independent than their typically developing peers at baseline, yet increased their independence during a 3-year period. Those who self-reported to the RTP were generally more independent than those who proxy-reported, which supports the need to distinguish between the service needs of subgroups during the transition phase.
