Megascops watsonii usta (Sclater, 1858): Dickinson & Remsen (2013); Clements et al. (2019); Gill et al. (2020; part: populations in southernmost Venezuela and Amazonian Colombia, Ecuador, Peru, Bolivia, and Brazil between the western banks of the Negro and the lower Tapajós and upper Xingu rivers). With type locality referred as Tefé, Amazonas, Brazil (Sclater, 1858), and corresponding to specimens in Clade B, M. usta is distributed over a wide geographic area in Amazonia, ranging from west of the Branco-Negro rivers throughout the Imerí, Napo, Inambari, Madeira and upper stretches of the Tapajos and Xingu AOEs. Strong statistical support for reciprocal monophyly, high degree of coalescence, and high uncorrected pairwise p-distances ranging from 2.1% (M. ater) to 6.4% (M. watsonii) differentiates this taxon from others in the Megascops atricapilla-M. watsonii complex. Morphologically variable with multiple morphs, mainly brown or red, but also gray, and not safely distinguishable solely based on morphology from the other species in the complex. There is geographical variation in the frequency of different morphs among populations. Apparently does not include morphs as dark in color as those found in M. watsonii and M. ater. Vocally distinct from M. watsonii, M. stangiae and M. atricapilla by on average slower-paced longsongs and shortsongs (Fig. 9; Tables 6, 8, and 10).Published as part of Dantas, Sidnei M., Weckstein, Jason D., Bates, John, Oliveira, Joiciane N., Catanach, Therese A. & Aleixo, Alexandre, 2021, Multi-character taxonomic review, systematics, and biogeography of the Blackcapped / Tawny-bellied Screech Owl (Megascops atricapilla-M. watsonii) complex (Aves: Strigidae), pp. 401-444 in Zootaxa 4949 (3) on page 428, DOI: 10.11646/zootaxa.4949.3.1, http://zenodo.org/record/464033

Electromagnetic shielding effectiveness of polyester fabrics with polyaniline deposition
No full textIn this study, conductive fabrics were developed by polymerizing aniline onto polyester (PET) woven fabrics. The fabric treatment was carried out by the chemical polymerization method at 0.5 M, 0.8 M and 1.2 M aniline concentrations. Hydrochloric acid as acidic medium and ammonium persulfate as oxidant were employed during the polymerization process. The polyaniline (PANI)-treated PET fabric structures were fully characterized and evaluated in terms of their electromagnetic shielding effectiveness, absorption and reflection characteristics, and tensile properties. Additionally, the fabrics were examined by scanning electron microscopy for their surface morphology and Fourier transform infrared spectroscopy for their chemical functionality. The electromagnetic shielding effectiveness and absorption and reflection characteristics were determined using a network analyzer with a frequency range from 15 MHz to 3000 MHz. The electrical characteristics were measured by the two-end method. It was concluded that the tensile strength values of the treated fabrics were enhanced when the amount of monomer in the concentrations increased as compared to the untreated fabrics. It is interesting to note that 1.2M treated fabric had the lowest tensile strength values as compared to the other treated fabrics. It was also found that a 0.5M concentration of PANI-treated fabric had the lowest surface resistivity since it showed the highest conductivity value. Another important finding is that the 0.8M aniline-treated fabric had the highest shielding effectiveness

Addressing domestic violence in primary care: What the physician needs to know
No full textDomestic violence (DV) is quite prevalent and negatively impacts the health and mental wellbeing of those affected. Victims of DV are frequent users of health service, yet they are infrequently recognized. Physicians tend to treat the presenting complaints without addressing the root cause of the problem. Lack of knowledge on adequately managing cases of DV and on appropriate ways to help survivors is commonly presented as a barrier. This article presents the magnitude of the problem of DV in the Arab world, highlights the role of the primary care physician in addressing this problem, and provides practical steps that can guide the clinician in the Arab world in giving a comprehensive and culturally sensitive service to the survivors of DV. © 2014 Jinan Usta and Rim Taleb.Al-Nsour M, 2009, J FAM VIOLENCE, V24, P569, DOI 10.1007-s10896-009-9255-2; Ambuel B, 2003, J COMP FAM STUD, V34, P113; Ambuel B, 1998, J AGGRESS MALTREAT T, V1, P72; American Congress of Obstetricians and Gynecologists, SCREEN TOOLS DOM VIO; [Anonymous], PHYS OBL PREV ID TRE; [Anonymous], 2008, JORDAN POPULATION FA; [Anonymous], 2005, EGYPT DEMOGRAPHIC HL; [Anonymous], 2009, POPULATION REPORTS E; Basile K.

Gelişmiş korozyon direnci için eloksallı metalik implantların elektrokimyasal davranışlarının incelenmesi
No full textA study about long-term corrosion behavior of anodized and nonanodized Ti6Al4V and MgAZ31B biomaterials was conducted
under controlled conditions. By applying 20V DC potential,
MgAZ31B alloys was anodized in phosphoric acid and potassium
hydroxide while Ti6Al4V alloys was anodized in phosphoric acid
and oxalic acid. Long-term experiments were carried out by
immersing them in deionized (DI) water, 3% NaCl and phosphatebuffered saline (PBS) solutions. The corrosion rate and pattern
were measured by electrochemical analysis. Also, as a result of
anodization, the natural oxide layer was observed on the material
surface, thus the corrosion rate is reduced and the life of the
biomaterial has been improved.Eloksallı ve anodize edilmemiş Ti6Al4V ve Mg AZ31B

Development and characterisation of polyaniline/polyamide (PANI/PA) fabrics for electromagnetic shielding
No full textIn this study, novel conductive fabrics were developed by polymerising of aniline onto the polyamide (PA)-knitted fabrics. The fabric treatment was done by the chemical polymerisation method at 0.5, 0.8 and 1.2 M aniline concentrations. Hydrochloric acid as acidic medium and ammonium per sulphate as oxidant were employed during the polymerisation process. The polyaniline (PANI)-treated PA fabric structures were fully characterised and evaluated in terms of their electromagnetic shielding effectiveness, absorption and reflection characteristics and tensile properties. Additionally, the fabrics were examined by scanning electron microscope (SEM) for the surface morphology and Fourier transform infrared spectroscopy for the chemical functionality. The electromagnetic shielding effectiveness, absorption and reflection characteristics were determined by Network Analyzer with a frequency ranged from 15 to 3000MHz. The electrical characteristics were measured by the two ends method. It has been concluded that the bursting strength values of the treated fabrics reduced when the amount of monomer in the concentrations decreased as compared to the untreated fabrics. It is interesting to note that 1.2M treated fabric had the highest bursting strength values as compared to the other treated fabrics. It was also found that 0.5M concentration of PANI-treated fabric had the lowest surface resistivity due to this it showed the highest conductivity value. Another important finding is that the 0.5M-aniline treated fabric had the highest shielding effectiveness
