One-dimensional TiO2 nanotubes film was synthesized on the Ti foil oxidized at 800℃ by hydrothermal method in a highly alkaline solution. The crystal structure, morphology and chemical state of the samples were characterized by X-ray diffraction, scanning electron microscope, transmission electron microscope and X-ray photoelectron spectroscopy. The result indicates that the TiO2 nanotubes film still remains rutile phase structure after hydrothermal treatment. The growth mechanism of TiO2 nanotubes is also discussed that includes dissolution, nucleation and growing process. The photocatalytic activity of TiO2 film is remarkably improved after hydrothermal reaction. Due to the one-dimensional tubular structure, TiO2 nanotubes film hydrothermally synthesized for 6 hours displays the highest photocatalytic degradation rate of methylene blue

Nowadays, due to the wide application and importance of active control methods such as Dielectric Barrier Discharge (DBD) plasma actuators, they are used in industries such as aerospace, propellers, and wind turbines to reduce the flow separation region and vortices around these objects (important applications). Accordingly, theories that can improve the efficiency in the aviation industry have drawn much attention. The larger the flow separation region around the airfoil, the more the vortices and return flows, and the larger the drag force. This leads to undesirable dissipation, especially in fuel, and instability of the aircraft (importance of the research work). The drag coefficient has a significant effect on the performance of the airplane, especially at high velocities. Hence, a method that can control the air flow on the airfoil and decrease the drag coefficient and the associated dissipation will be helpful. In this research, the airflow over a NACA0012 airfoil has been designed and analyzed in ANSYS Fluent software. In this method, two-dimensional airfoil aerodynamics is considered, and the high-Re airflow around the airfoil is analyzed. Moreover, the UDF code of the plasma is defined as a body force at an optimal and sensitive location of the airfoil (flow separation region). Subsequently, the drag coefficient is evaluated at a constant Re and different angles of attack. As a result, the drag coefficient at different angles of attack is smaller for when plasma is defined on the airfoil (plasmaon) compared to when plasma is inactive (plasma-off). Furthermore, it is shown that the pressure distribution around the airfoil is improved using plasma actuators.

Reflectance, absorbance and phase difference of the polarization modes (s-polarized) and (p-polarized) were described theoretically by using optical multilayers of thin films. A high reflectance layers with very low absorbance at different incident angles (0°,30°,60°,80°) can be achieved in the infrared region by adopting design(Air|HL|4 PbTe). High refractive index PbTe and low refractive index NaCl are used in the infrared region at central wavelength 10 µm. Design (Air|HL|3 Glass) adopted in the visible region by using TiO2 and CaF2 materials at central wavelength 550 nm. Spectral band width of reflectance remain large (7 µm-18 µm) for s-polarization with increases of the incident angles of the light, but spectral band width of reflectance for p-polarization are decreasing with an increase of the angles where the smallest for incident angle (80°) that reach (6.2 µm to 14 µm) due to increase of the phase shift between two modes of polarization. The absorbance of p-polarization has a larger value than the absorbance of s-polarization mode that causing a decrease in the reflectivity of the TM modes than TE modes.

In the present study, the effects of laser irradiation on microstructure, morphology and hardness of yttria-stabilized tetragonal zirconia (ZrO2) commercially known as ZirCAD are examined. Three specimen discs were cut from the ZirCAD block. After polishing two of them were irradiated by Nd: YAG pulsed laser, with 100 and 150 laser pulses respectively and the remaining one unexposed specimen was kept as a standard. The XRD analysis confirmed that no phase change occurred after laser irradiation however an increase in dislocation line density (DLD) was observed. The surface morphology was observed by optical and scanning electron microscopy (SEM). Laser irradiation initially caused the upper surface to melt therefore resulting in a smooth and glazed surface. Further increase in laser pulses produced porosity within the sample. The optical microscopy revealed that the crater size decreased and the heat-affected zone increased with the increased number of laser pulses. Vickers hardness was employed to observe the hardness of unirradiated and irradiated samples and a 32% increase in hardness was observed when the material was irradiated by 100 laser pulses. The glazed surface exhibited more hardness as compared to the unirradiated and porous surfaces. The improved surface morphology and high hardness achieved in this work with laser irradiation for ZirCAD ceramic are quite beneficial in dental applications.

Photocatalytic wastewater treatments applying the semiconductor photocatalysts to remove toxins or pollutants from wastewater become more important nowadays. In this study, the photocatalytic study was firstly conducted on the photodegradation of rhodamine B (RB) dye in tap water by using TiO2 as photocatalysts under short wavelength (high energy) UV-C light irradiation. The results show that a considerable increase in the degradation of RB can be obtained through a combination of TiO2 and UV-C light. In addition, hydrogen peroxide (H2O2) was added in the RB solution containing TiO2 to improve the degradation efficiency of RB dyes. The result shows that 98 % degradation efficiency of 20 ppm RB is achieved within 180 min irradiation time in the solution containing 0.5 g/l TiO2 and 1 M H2O2 concentrations, which is higher than the reported literature value.

The simulation model for MCNP5 code was used to study the effect of the gold nanoparticle (AuNPs) in cancer breast samples. The dose rate distribution of AuNPs in water and breast phantom was calculated using MCNP5 code. For inhomogeneities, cone cells were designed to calculate dose distribution around Ir-192 source in breast and inhomogeneous medium that includes gold nanoparticles at different concentration. Both barometers, the track length energy deposition tally (F6) and pulse height tally (*F8), were used. The result indicated that the F6 is better than *F8 for radiation dose calculation. Angular doses distribution in water was compared with data published for tally F6 and*F8 with the different percentage range of 0.0136 to 0.3019% for tally F6 at the average angle of 5˚and 175˚respectively. For *F8 tally, different percentage range of - 0.0014 to 0.8253 % was obtained at an average angle of 75˚and 5˚ respectively. For breast phantom, the result of the F6 tally with the *F8 tally was compared. The difference in calculations between the two tallies in the angular anisotropic distribution was found to be in the range from 0.0514 to 0.4596% at the average angle of 15 ˚ and 175 ˚ respectively. The obtained results showed that the AuNP dose increases when the concentration increases up to ten percent (100 mg/ml), and then decreases for concentration higher than ten percent. The concentration of AuNPs greater than ten percent is not recommended. The results indicated that tally F6 is a good tool to calculate the effect of inhomogeneities due to breast cancer on brachytherapy.

Keberhasilan individu emerging adult menjalin intimasi dengan pasangannya tidak dapat dilepaskan dari proses pembentukan identitas yang terjadi pada periode perkembangan sebelumnya. Penelitian ini bertujuan untuk menguji hubungan antara dimensi identitas yang terdiri dari komitmen, eksplorasi mendalam, dan peninjauan kembali dengan intimasi pada emerging adult yang menjalin hubungan romantis. Partisipan penelitian adalah 165 emerging adult yang sedang menjalin hubungan romantis di Kota Surabaya. Pengambilan data dilakukan dengan metode accidental sampling dan partisipan mengisi inform consent penelitian sebelum mengisi kuesioner penelitian yang tersedia dalam bentuk kertas dan online. Alat ukur Stenberg Triangle Scale dan Utrecht- Management of Identity Commitments Scale digunakan untuk mengukur intimasi dan tiga dimensi identitas. Hipotesis penelitian diuji dengan menggunakan analisis korelasi Pearson dan analisis regresi. Hasil analisis menemukan bahwa hanya dimensi komitmen identitas yang berhubungan positif dengan intimasi (r = 0,230, p 0,001) sedangkan dimensi eksplorasi mendalam dan peninjauan kembali komitmen tidak berhubungan dengan intimasi. Temuan ini mengindikasikan bahwa keberhasilan pembentukan identitas dapat menjadi fondasi dasar bagi individu untuk menjalin hubungan romantis.The success of emerging adult in establishing intimacy with their partner cannot be separated from the identity development process that occurred during the previous development period. This study aims to examine the relationship between the dimensions of identity that consist commitment, in-depth exploration, and reconsideration of commitment to intimacy in emerging adults who are in on-going romantic relationships. The participants were 165 emerging adults who are in a romantic relationship in Surabaya. Data were collected using the accidental sampling method and participants filled out the research information consent before filling out the research questionnaire which available in paper and online form. Stenberg Triangle Scale and Utrecht- Management of Identity Commitments Scale are used to measure intimacy and three dimensions of identity. The hypothesis was tested using the Pearson correlation analysis and regression analysis. The results found that only the commitment dimension was positively related to intimacy (r = 0,230, p 0,001) while in depth exploration and reconsideration of commitment variable was not associated with intimacy. These findings suggest that the fact that identity development can provide a basic foundation for individuals to enter into romantic relationships.

Banyak studi mengatakan bahwa orang-orang dengan relational mobility tinggi memiliki kesempatan untuk membentuk hubungan baru dan mengakhiri hubungan lama dengan mudah. Namun, penelitian yang mengeksplorasi perubahan values ditinjau dari mobilitas individu belum banyak dilakukan. Penelitian ini bertujuan untuk meneliti peran relational mobility terhadap perubahan work values. Penelitian ini menggunakan desain cross-sectional dan menguji 240 partisipan penelitian dengan mengontrol variabel usia dan area tinggal (urban versus rural). Analisis regresi linier dilakukan dua tahap untuk menguji peran relational mobility terhadap work values. Hasil penelitian menunjukkan, relational mobility secara positif memprediksi perubahan work values (terutama nilai achievement, balance, independence, influence, integrity, power, respect, and status) dengan ataupun tanpa mengontrol area tinggal dan usia. Sementara itu, area tinggal dan usia mempengaruhi peran relational mobility terhadap work values, kecuali pada value integrity dan power.Many research investigated that individuals high in mobility have opportunities to form new connections and terminate old ones. However, research that explore values changing in terms of individual’s mobility has not been instigated. This research aimed to investigate the role of relational mobility in changing works values. This study used a cross sectional design to examine 240 participants by controlling age and living area (i.e., urban versus rural). Two steps linear regression was used to examine the role of relational mobility on work values. The result indicated that relational mobility positively predicted a change in most  work values (i.e., achievement, balance, independence, influence, integrity, power, respect, and status) with or without controlling living area and age. Meanwhile, living area and age influence the role of relational mobility in work values but not in integrity and power.
Survey of endocrinologists managing recovery from anabolic androgenic steroid induced hypogonadism

Lay summary

Anabolic steroids (also known as ‘steroids’) are banned drugs like testosterone, which make muscles bigger in men. These drugs are dangerous because they stop the testes from making natural testosterone and can cause heart attacks. Men stopping steroids have very low testosterone, which makes them feel weak, depressed, suicidal, infertile, and unable to have erections. We surveyed over 100 doctors to find out how they treat men giving up steroids. We report that doctors differ widely in the way they treat these men. Most doctors simply advise men to wait for the natural recovery of testosterone levels to happen. But 20% of doctors give men drugs to boost testosterone and make men feel better. Unfortunately, many patients had not recovered by the time of our survey. In summary, our survey highlights differences and limitations in the treatment of men giving up steroids. The use of steroids is increasing rapidly among young men, so we recommend further work to improve the treatment of men who are motivated to give up steroids.

Graphical abstract

Background

The distribution of the blood vessel network at any point in time in any body tissue may provide valuable information with regard to the tissue condition, whether it is in a growth, declining or recovery phase as well as giving insights as to its angiogenesis functionality. The blood vessel three-dimensional network of the endometrium goes through a process of change over a relatively short period of 4 weeks on average. It is well accepted that angiogenesis within the endometrium is closely related to the success or failure of the implantation of the embryo.

Objective and rationale

Our study aims to present a method to follow the three-dimensional evolution of the superficial blood vessel distribution in the endometrium throughout the uterine cycle.

Method

This method utilizes differences in the observed broadband colors of the blood vessels in order to assess their depth coordinate below the endometrial tissue surface. We implemented the method using microscopic images of fresh, ex vivo, endometrial samples of different cycle days to obtain the statistical evolution track of the superficial blood vessel population in both human and animal (swine) samples.

Outcomes

In human samples, we observed a systematic and consistent trend in the blood vessel diameter distribution at different tissue depths. We demonstrate that the magnitude of this trend evolves throughout the course of the female cycle.

Wider implications

This method has the potential to further our understanding of the mechanisms of angiogenesis in tissues other than the endometrium. We propose that this method may also contribute to more precise endometrial dating and may assist in more accurate determination of embryo transfer timing within in vitro fertilization treatments.

Lay summary

The inner lining tissue of the womb (uterus) is called the endometrium, and it undergoes significant changes during the menstrual cycle.

The endometrium blood vessel network goes through rapid changes during the cycle.

We have developed a new method to measure this through surface imaging of the endometrium.

We use samples of endometrial tissues collected at different dates in the cycle to show how useful this method is in evaluating the development of the endometrium.

The method may also be used to investigate different processes of generating new blood vessels and may help to support dating the development of the endometrium.

Our work offers a non-invasive or minimally invasive method which reveals the three-dimensional blood vessel network and may be used to help in a variety of diagnoses. For example, this method may be used to see how receptive the uterus is during in vitro fertilization treatment.

The monograph considers numerous carbon structures, both real and hypothetical, the possibility of the formation of which is not excluded in principle. In addition to the structures of diamond and graphite, such structural forms of carbon as carbon black, onions, graphene, nanotubes, fullerenes, glassy carbon and ultradispersed diamond are described in detail. Among the hypothetical structures, much attention is paid to structures, that are built only on sp2 hybridized bonds: Н-6, bct-4 and others. The hypothetical structures of carbyne and carbinoids, which contain sp1 hybridized bonds, are considered also. The large volume of material in the book is devoted to the analysis of the regularities of mutual transformations of carbon phases at high pressures and temperatures. The influence of structural defects on the mechanisms and kinetics of phase transformations is described. Particular attention is paid to the study of phase transformations of carbon structures under high-temperature shock compression. The monograph also discusses the features of crystal chemistry and phase transformations in boron nitride, which is a crystallographic analogue of carbon. A number of sections are devoted to the features of X-ray diffraction analysis of carbon structures. The book is intended for – materials scientists, physicists, as well as for university teachers, graduate students and students of relevant specialties.
