Objective: To assess the effects of physical and depressive symptoms on the sexual life of women in the climacteric period.
Methods: This study was conducted with 572 women at a university hospital. ...The Beck Depression Inventory (BDI), Menopause Rating Scale (MRS) and Female Sexual Function Index (FSFI) were used to evaluate depressive symptoms, intensity of menopausal symptoms and sexual function.
Results: Sexual dysfunction and depressive symptoms were determined in 86.4% and 54.9% of the women, respectively. In univariate analysis, women without health insurance, with low income, being married for longer than 21 years and being in menopause had low FSFI but high BDI and MRS scores. In multiple regression analysis, advanced age of women, women with low income, unemployed women, low educated women and their husbands and women with depressive symptoms had low FSFI scores. There was a negative relationship between total FSFI and MRS and BDI scores.
Conclusion: Determination and treatment of sexual, emotional and physical problems in the climacteric period are very important for the improvement of the quality of life of women.
Copper etching is considerably important process in electronics industry, particularly in the fabrication of printed circuit board. Various etchants can be used for this purpose, but nowadays cupric ...chloride is more accepted etchant, because of its high etch rate and easy regeneration properties. In the present study, copper etching process with cupric chloride etchant was investigated. In the etching of copper, the most important etching parameter is etch rate, therefore the investigation was based on the various effects on etch rate. The influence of etchant concentration, additives and etching temperature were examined. It is also important to regeneration/recycle of waste etchant from environmental point of view. Thus, various cupric chloride etchant regeneration processes were investigated.
•RAC with 5% SF increases the ratio of tensile splitting strength to compressive strength.•The ratio of tensile splitting strength to compressive strength of RAC decreases with 10% SF.•Suitable ...proportion of the replacement of NA with RA is 30%.
Experimental studies for determining the mechanical and the physical properties of the recycled aggregate concrete (RAC) with and without silica fume (SF) is inspired by the Urban Renewal Law which regulates circumstance of existing structures in Turkey. According to this law, the structures which have been built lacking quality engineering, built without considering urban planning, and are risk prone (i.e. susceptible to earthquakes), will be demolished and rebuilt using recent Turkish Standards. Implementing this law is expected to increase the quantity of waste concrete. Minimizing waste disposal through structural and non-structural areas without a harmful effect on nature has a vital importance in Turkey. In this study, demolished-building-rubble is used as recycled aggregate (RA) with and without SF in concrete mixtures. Twelve concrete mixtures in three groups are produced, and the mechanical properties of the concrete specimens such as compressive strength, tensile splitting strength and elasticity modulus, and physical properties of the concrete specimens such as density and water absorption ratio are determined. The proportion 30% of RA in concrete mixtures is proposed as the optimum ratio. Low regression coefficient of RAC with SF is observed in the short-term. It is found that 5% SF content in the RAC is more convenient to improve the low properties of RAC (i.e. compressive strength).
We have studied the sensitivity to flavor changing neutral current interaction of top and Higgs boson at the future circular collider in the hadron-hadron collision mode (FCC-hh). Our main concerns ...are the processes of pp→th (FCNC production) and pp→tt¯ (one top FCNC decay) which contributes to the single lepton, at least three jets and the missing energy transverse in the final state. On the one hand FCC-hh offers very high luminosity and large cross section for these signal processes, on the other hand signal can be distinguished from background which needs application of ingenious methods. Here, we have inspired and followed the searches at the LHC using our analysis path and enhanced attainable limits obtained on the possible top-Higgs FCNC couplings phenomenologically. We obtain new limits which are beyond the current experimental limits obtained from different channels and processes at the LHC. The potential discovery or exclusion limits on branching ratios for tqH FCNC interactions can be set BR(ηuc)disc=9.08×10−6 or BR(ηuc)exc=2.78×10−6 at an integrated luminosity of 30ab−1, respectively. Our results are compatible with the other channels already studied at FCC-hh.
We investigate the sensitivity of the anomalous dimension-8 neutral triple gauge couplings via process pp→ννγ with fast detector simulation including pile-up effects for the post LHC experiments. The ...transverse momentum of the final state photon and missing energy transverse distributions are considered in the analysis. We obtain the sensitivity to the CB˜W/Λ4, CBB/Λ4, CWW/Λ4 and CBW/Λ4 couplings at HL-LHC and HE-LHC with an integrated luminosity of 3 ab−1 and 15 ab−1, respectively. Finally, our numerical results show that one can reach the constraints at 95% confidence level without systematic error on CB˜W/Λ4, CBB/Λ4, CWW/Λ4 and CBW/Λ4 couplings for HL-LHC (HE-LHC) as −0.38;0.38(−0.12;0.12), −0.21;0.21(−0.085;0.085), −1.08;1.08(−0.38;0.38) and −0.48;0.48(−0.25;0.25), respectively. They are better than the experimental limits obtained by LHC.
After the recent discovery of a neutral Higgs boson with a mass about 125 GeV, we assess the extend of discovery potential of future circular hadron collider (FCC-hh) for a charged Higgs boson in the ...bottom and top quark decay channel. The charged Higgs boson can be produced through the pp→h−t+X process with a subsequent decay h−→bt¯ channel. This decay channel is particularly important for studying the charged Higgs boson heavier than the top quark. We consider an extension of the standard model Higgs sector, namely two Higgs doublet model (2HDM), and perform a dedicated signal significance analysis to test this channel for the FCC-hh running at the center of mass energy of 100 TeV and the integrated luminosity of 1 ab−1 (initial), 3 ab−1 (comparison with HL-LHC) and 30 ab−1 (ultimate). We find that an important part of the parameter spaces of two Higgs doublet model is examinable at the FCC-hh.
In this study, we investigate the process pp→W±γ for the physics potential of the FCC-hh with s=100 TeV to examine the anomalous WWγ couplings defined by three CP-conserving and two CP-violating ...effective operators of dimension-6. The analysis containing the realistic detector effects is carried out in the mode where W± bosons in the final state decay into the leptonic channel. The best sensitivities obtained from the process pp→W±γ on the anomalous couplings CWWW/Λ2 and CW,B/Λ2 determined by CP-conserving effective Lagrangians are −0.010;0.010 TeV−2 and −0.40;0.41 TeV−2, while CW˜WW/Λ2 and CW˜/Λ2 couplings defined by CP-violating effective Lagrangian are obtained as −0.003;0.003 TeV−2 and −0.32;0.33 TeV−2 at the FCC-hh with Lint=30 ab−1. However, if the systematic uncertainty is included, we obtain reduced sensitivities on the anomalous WWγ coupling. The results are compared for assumed systematics of 5% and 10%.
Optical flow provides an opportunity to elevate the resolution and sensitivity of deflection sensing in background-oriented schlieren (BOS). Despite extensive relevant literature within the field of ...computer vision, there is a lack of proper quantification of its abilities and limitations with regard to the state-of-the-art BOS experiments. Thus, this study performs an assessment of accuracy and resolution limits in different flow field scenarios utilizing background patterns generated with random dot and wavelet noise distributions. Accordingly, a synthetic assessment over a theoretically generated Prandtl–Meyer expansion fan is conducted with variations introduced in the background patterns and operational parameters of optical flow. A clear superiority of accuracy and resolvable range of density gradient amplitudes over cross-correlation is demonstrated. Moreover, an experimental assessment of supersonic flow features over multiple wind tunnel models is performed. The influence of experimental constraints, limitations and uncertainties related to the application of optical flow in BOS and its comparative performance against the block-matching counterpart is characterized.

The top quark flavor changing neutral current (FCNC) processes are extremely suppressed within the Standard Model (SM) of particle physics. However, they could be enhanced in a new physics model ...Beyond the Standard Model (BSM). The top quark FCNC interactions would be a good test of new physics at present and future colliders. Within the framework of the BSM models, these interactions can be described by an effective Lagrangian. In this work, we study tqγ and tqZ effective FCNC interaction vertices through the process e−p→e−Wq+X at future electron proton colliders, projected as Large Hadron electron Collider (LHeC) and Future Circular Collider-hadron electron (FCC-he). The cross sections for the signal have been calculated for different values of parameters λq for tqγ vertices and κq for tqZ vertices. Taking into account the relevant background we estimate the attainable range of signal parameters as a function of the integrated luminosity and present contour plots of couplings for different significance levels including detector simulation. We find the sensitivities to the branching ratios (BR(t→qγ)=7.5×10−6, BR(t→qZ)=3.5×10−5) and (BR(t→qγ)=8.5×10−7, BR(t→qZ)=6.0×10−6) for an integrated luminosity of 2ab−1 at LHeC and FCC-he, respectively.
•Cement and waste cementitious materials contain high radionuclide concentrations.•Radioactivity of concrete containing these materials is required to be characterised.•Recycling silica fume and fly ...ash within concrete increases 226Ra, 232Th and 40K activity levels.•Barite aggregate can reduce these activities in tailored mixing proportions of concrete shields.
The recycling of hazardous materials within new composites has a sustainable importance as it contributes on the reduction of high radionuclide concentrations. In this study, the effect of cementitious materials i.e. viscosity modifier, silica fume and fly ash on the 226Ra, 232Th and 40K activity levels of barite concrete shields was researched by using different mixing compositions in terms of binder content, w/b ratio and the amount of supplementary cementitious materials. In comparison to cement, silica fume and fly ash used in the production of concrete shields were found to have significantly higher activity levels of 40K, as well as 226Ra, 232Th and 40K, respectively. The 226Ra, 232Th and 40K activity levels of concrete shields range between 2.2 and 20.7 Bq kg−1; 2.6 and 7.0 Bq kg−1; 51.5 and 89.3 Bq kg−1, respectively. These activity values were found similar or less than those of building materials in the world. These satisfactory results are mostly caused by the barite source which has lower radioactivity levels. The concrete mixture details used in the study caused significant variation in the natural radioactivity of barite concrete shields. The introduction of silica fume which has high 40K activity levels and fly ash with high 226Ra, 232Th and 40K activity levels compared to cement and barite aggregate, significantly increased the radiological hazard parameters, although all results were found to be below the limits recommended by international reports. In conclusion, 226Ra activity levels of the concrete shields were significantly increased (up to 8.4 times) by the variation of mix design parameters used in comparison with concrete mixtures that have the least 226Ra activity level. The 232Th and 40K activity levels were as well increased in relatively less amounts (1.7 and 0.73 times higher, respectively).
