    Use of the UPOINT Classification in Turkish Chronic Prostatitis or Chronic Pelvic Pain Syndrome Patients
    (Elsevier Science Inc, 2016) Arda, Ersan; Çakıroğlu, Basri; Taş, Tuncay; Ekici, Sinan; Uyanik, Bekir Sami
    OBJECTIVE To determine the positive subdomain numbers and distribution of the UPOINT classification in chronic prostatitis and to compare the erectile dysfunction (ED) pattern. MATERIALS AND METHODS From 2008 to 2013, 839 patients with symptomatic chronic prostatitis or chronic pelvic pain syndrome were included in this study. The correlation between UPOINT domains and National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) total score, subscores, and the 5-item International Index of Erectile Function scores were evaluated retrospectively. RESULTS The mean patient age was calculated as 37.7 +/- 7.4 (range 21-65). The average total NIH-CPSI score was determined as 9.07 (range 1-40) and the average positive UPOINT subdomain number was determined as 2.87 +/- 0.32 (range 1-6). Subdomain patient numbers and rates were calculated as 529 urinary (63%), 462 psychosocial (55%), 382 organ specific (45%), 290 infection (34%), 288 neurological or systemic (34%), and 418 tenderness (skeletal muscle) (50%), respectively. It was determined that ED, determining the subdomain of sexual dysfunction in patients, was positive in a total of 326 (39.9%) patients, with 220 patients having mild (26.2%), 76 mild to moderate (9.1%), 19 moderate (2.3%), and 5 with severe (0.6%) ED. A statistically significant correlation was not determined between the 5-item International Index of Erectile Function score and UPOINT subdomain number and NIH-CPSI score. CONCLUSION It has been determined that although there is a strong and significant correlation between UPOINT classification and NIH-CPSI score in Turkish patients with chronic prostatitis or chronic pelvic pain syndrome, the inclusion of ED as an independent subdomain to the UPOINT classification is not statistically significant.

    The role of masonry infills on the interstory drift demand of reinforced concrete frames
    (Elsevier Sci Ltd, 2024) Etemadi, Ali; Balkaya, Can
    Most frame buildings, especially those with shear -type moment resistance frames, are affected by masonry infill panels, which change the mechanical properties of whole systems in a big way. In turn, seismic performance varies depending on the infill panel and frame interactions. In conventional structural design practice, such interaction has been overlooked. This study looks at the range of local displacement demands in shear -type frames with and without infill panels. Generic frames are developed by tuning the story stiffness and mass to produce a reasonable period range between 0.2 and 2.0 s. The masonry infill panels are simulated through equivalent diagonal struts. A Bouc-Wen-based hysteretic model is applied to incorporate the post -yielding hysteresis degradations of both columns and masonry panels. The hysteresis loop control parameter values are also given for incorporating masonry infill properties. The correlation analysis between the strength and stiffness of RC frames and masonry infills is supplied as an instrument for calibrating the hysteretic model. In the collection of records, there are a lot of near -fault ground motions, which puts a lot of seismic demands on the buildings. The modification factors via regression analysis are proposed using over 1254 nonlinear response history analyses. This modification factor is figured out by looking at the difference between the mean drift spectrum for a set of generic frames that are both bare and filled. The nonlinear analysis shows that residual drift demands can be reduced in the case of panel effects that exist for masonry-infilled mid -rise RC shear -type frames.

    Evaluation of extractability of 2,4,6-trinitrophenol by secondary amine extractant in alcohols: Equilibrium and molecular dynamic study
    (Elsevier, 2017) Uslu, Hasan
    Extractive separation of 2,4,6-trinitrophenol (picric acid, PAH) from its aqueous solutions was examined at constant temperature of 298.2 K. The experiments were studied on the extraction of PAH (0.061 mol kg(-1)) by Amberlite LA2, a secondary amine diluted in five different alcohols such as isopropyl alcohol, isoamyl alcohol, hexanol, heptanol, and decanol. In addition to reactive extraction, experiments on physical extraction were also performed by pure diluents. Experimental results obtained from batch extraction were evaluated in terms of distribution coefficients (K-D), extraction efficiency (E), and loading factors (Z). The highest synergistic effect was achieved with isopropyl alcohol in LA-2 at a concentration of 0.588 mol kg(-1) as 98.36%. The highest value of probable equilibrium constants for the complex between acid and amine (1:1), K-11 was calculated to be 11.62 for isopropyl alcohol at 0.588 mol kg(-1) LA-2 concentration. Kinetic and potential energies of components during reactive extraction in the organic phase have been determined by molecular dynamic modeling for picric acid + isopropyl alcohol + secondary amine. The values of energy, per atom, for mixture picric acid + isopropyl + secondary amine were respectively: similar to 30,000 kcal/mol, similar to 15,000 kcal/mol, similar to-50,000 kcal/mol and similar to-60,000 kcal/mol.

    Constitutive Model and Mechanical Properties of Grade 8.8 and 10.9 High-Strength Bolts at Elevated Temperatures
    (Asce-Amer Soc Civil Engineers, 2024) Saglik, Huseyin; Etemadi, Ali; Chen, Airong; Ma, Rujin
    This paper presents an experimental study on the determination of the mechanical behaviors of Grade 8.8 and 10.9 high-strength bolts at elevated temperatures. Strength reduction coefficients are obtained based on test results at temperatures ranging from 20 degrees C to 900 degrees C, for both yield and ultimate stresses. Simplified expressions are presented to identify the strength reduction factors at considered temperatures. At 400 degrees C, the yield and ultimate strengths of bolts decrease by 30%-35% for both grades compared to those in ambient temperature. Yield strengths are 30% and 20% of yield strengths of Grade 8.8 and 10.9 bolts at ambient temperature, respectively, when the temperature exceeds 500 degrees C. The ultimate strength decreases slightly slower than the yield strength at high temperatures. Although the decrease in ultimate strength follows the decrease in yield strength at elevated temperatures, it is slightly slower. About 3%-6% of yield and ultimate strengths at ambient temperature remain for both grades at 700 degrees C. Moreover, a series of expressions are provided to obtain the full range stress-strain curve of high-strength bolts at elevated temperatures. Comprehensive literature studies are taken into consideration to propose a more generalized description of the stress-strain curves. The proposed model can be fully drawn by only using elastic modulus, yield, and ultimate stresses at ambient temperature. It is shown that the proposed model has enough efficiency to describe the general material behavior at elevated temperatures.

    Adsorption Studies of Lactic Acid by Polymeric Adsorbent Amberlite XAD-7: Equilibrium and Kinetics
    (Amer Chemical Soc, 2017) Uslu, Hasan; Majumder, Subhajit
    The present study deals with the separation of lactic acid (LA) by a polymeric adsorbent Amberlite XAD-7. Equilibrium and kinetic studies were carried out to investigate adsorption of LA on Amberlite XAD-7 at three different temperatures (298, 308, and 318 K). Equilibrium studies revealed the optimum dose of Amberlite XAD-7 as 2.5 g. The adsorption equilibrium time was determined as 90 min. Adsorption isotherms such as Freundlich, Langmuir, Temkin, and Dubinin-Radushkevich were validated using the obtained experimental data. Langmuir isotherms showed better fitting with the experimental data with R-2 = 0.99. Pseudo-second-order model and Elovich model were used to fit the adsorption system. Study also revealed 99% removal of LA using Amberlite XAD-7.

    Extraction of Citric Acid and Maleic Acid from Their Aqueous Solutions Using a Phosphorus-Bonded Extractant, Tri-&ITn&IT-octylphosphineoxide, and a Secondary Amine, Dioctylamine
    (Amer Chemical Soc, 2018) Hasret, Erdem; Kirbaslar, Sah Ismail; Uslu, Hasan
    The aim of this study is to investigate the extraction of citric acid and maleic acid from their aqueous solutions using different solvent-extractant mixtures in order to find the most effective composition for the extraction. Citric and maleic acids are chosen as the carboxylic acids due to their commercial worth in the industrial processes. Carboxylic acids are recovered from their aqueous solutions by reactive extraction, a promising liquid-liquid extraction technique, using trioctylphosphineoxide (TOPO), and a secondary amine called dioctylamine (DOA). TOPO has been chosen as an extractant since it has low water solubility, high stability, and it is more environmentally friendly than the amine-type extractants. For other amine extractants used in reactive extraction processes, there is a lack of study in the literature about the extraction of these acids with DOA. Extractants were dissolved in nine different solvents (butanol, decanol, octanol, isoamylalcohol, octane, decane, methylisobutylketone, and diisobutylketone) having different chemical structures. All experiments were carried out at 298.15 K. Comparisons of the results were made using, the distribution coefficient (D), loading factor (Z), and the extraction yield (%E). It has been observed that a considerable amount of citric acid and maleic acid extraction was achieved using DOA (in the range of 13.95-99.19% and 31.94-99.41% according to the diluent used for citric acid and maleic acid, respectively) compared to that achieved with TOPO (in the range of 0.81-67.12% and 16.25-89.33% according to the diluent used for citric acid and maleic acid, respectively).

    Equilibrium Data on the Reactive Extraction of Picric Acid from Dilute Aqueous Solutions Using Amberlite LA-2 in Ketones
    (Amer Chemical Soc, 2017) Uslu, Hasan; Marti, Mustafa Esen
    The present study is on the reactive extraction of picric acid (HPc, 2,4,6-trinitrophenol) from dilute aqueous solutions by organic phases containing Amberlite LA-2 (ALA 2) as extractant dissolved in four types of ketones. The studies were performed at 298, 308, and 318 K, and the results were used to calculate the values of distribution coefficient (KD), loading factor (Z), and degree of extraction (E%). Initial HPc concentration was kept constant at 0.061 mol.kg(-1). The maximum KD was obtained as 60 using methyl ethyl ketone when initial concentrations of PA and ALA-2 were 0.061 and 0.59 mol.kg(-1), respectively. The extraction efficiency was 98.36% under these conditions. Moreover, z-values between 0.09 and 0.27 were obtained in the ranges of parameters studied. Calculated values show that 1:2 picric acid-ALA-2 complex dominates the extraction process.

    Comparison of antagonist mild and long agonist protocols in terms of follicular fluid total antioxidant capacity
    (Elsevier Taiwan, 2018) Mathyk, Begum Aydogan; Cetin, Berna Asian; Vardagli, Duygu; Zengin, Emel; Sofiyeva, Nigar; Irez, Tulay; Ocal, Pelin
    Objective: A high dose of prolonged gonadotropins can yield higher numbers of oocytes and embryos. The high dose or prolonged regimens can be associated with ovarian hyperstimulation syndrome (OHSS), multiple gestations, emotional stress, economical burden and treatment dropout. In mild stimulation lower doses and shorter duration times of gonadotropin are used in contrast to the conventional long stimulation protocol in IVF. It has been proposed that supraphysiologic levels of hormones may adversely affect endometrium and oocyte/embryo. Also it has been proposed that oxidative stress (OS) may alter ovarian hormone dynamics and could be further affected by additional exogenous hormonal stimulation. Therefore our aim was to compare follicular fluid total antioxidant capacity (TAC) in antagonist mild and long agonist stimulations. Materials and Methods: Forty patients received antagonist mild stimulation, starting on the 5th day of their cycle and forty patients received long agonist treatment. Seventy-five patients undergoing their first IVF cycle were included in the final analysis. Follicular fluid (FF) samples were analyzed for estradiol (E2), antimullerian hormone (AMH) and TAC. Results: FF-Total antioxidant capacity (TAC) levels were higher in the long agonist group as opposed to the antagonist group [1.07 +/- 0.04 mmol Trolox equivalent/L vs 1 +/- 0.13 mmol Trolox equivalent/L] (Fig. 1). Pregnancy rates were not significantly different between the two treatments. The FF-TAC levels were not different among infertility etiologies (Fig. 3). FF-TAC levels did not have a direct correlation with pregnancy but a positive correlation with the total gonadotropin dose was observed. Conclusion: Patients with good ovarian reserves and under the age of 35 effectively responded to mild stimulation treatment. Using lower amounts of gonadotropin, yielded less FF-TAC levels in patients who underwent antagonist mild protocol. In patients under the age of 35, antagonist mild stimulation is a patient friendly and effective procedure when undergoing their first IVF cycle.

    Solvent Polarity Effect when Amberlite-LA2 Is Used in the Extraction of Picric Acid
    (Amer Chemical Soc, 2017) Uslu, Hasan; Datta, Dipaloy; Bamufleh, Hisham S.
    The separation and recovery of picric acid (0.061 mol-kg(-1)) from its aqueous solution was studied at a fixed temperature of 298 K. The extraction experiments were performed by using a secondary amine, Amberlite-LA2 (ALA2), dissolved in five different solvents such as dichloromethane (DCM), dodecanol, toluene, benzene, and dodecane. Physical extraction data were also produced by pure solvent alone. The experimental data obtained from the batch studies were analyzed by calculating the distribution coefficient (K-D), extraction efficiency (%E), and loading factor (Z). The highest synergistic effect was achieved with DCM in ALA2 at a concentration of 0.588 mol.kg(-1) as 83.61%. The equilibrium constants for the complex formation between acid and amine (1:1 and 2:1) were calculated for all the solvents applying the mass action law.

    (Amer Chemical Soc, 2017) Uslu, Hasan; Datta, Dipaloy; Bamufleh, Hisham S.
    Montmorillonite (Mt) clay was used to remove zinc (Zn2+) ion from the aqueous solution. This clay material was modified (Mt-TOA) by impregnating trin-octylamine (TOA), a tertiary amine. The experiments on equilibrium and kinetics were done to analyze the effect of adsorbent amount (w, 0.05 to 0.3 g for Mt, 0.01 to 0.06 g for Mt-TOA), initial Zn2+ ion concentration (C-0, 15 mg.L-1 to 35 mg.L-1), pH (1 to 9), and contact time (t, 0 to 100 min) on the efficacy of both adsorbents. With a greater amount of adsorbent, the intake capacity of Mt and Mt-TOA for Zn2+ ion removal was found to lower but there was an increase in the separation efficiency. The optimum amount of Mt and Mt-TOA was found to be 0.1 and 0.01 g, respectively. The pH of the aqueous solution could be maintained at 7 to achieve a better adsorption of Zn2+ ion. In the kinetic experiments, after 90 min, the separation efficiency of Zn2+ ion from aqueous solution reached to a value of 86.68% with Mt (0.1 g) and 84.56% with Mt-TOA (0.01 g). Modeling of the equilibrium and kinetic data were done by using the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich, and by using the pseudo-first-order, pseudo-second-order, and intraparticle diffusion models, respectively, and the best fitted model is presented.

    Adsorptive Separation of Lead (Pb2+) from Aqueous Solution Using Tri-n-octylamine Supported Montmorillonite
    (Amer Chemical Soc, 2017) Datta, Dipaloy; Uslu, Hasan
    Divalent lead present in the water stream was removed by using adsorption techniques with montmorillonite clay (Mt) modified with tri-n-octylamine (Mt-TOA). Batch adsorption data at equilibrium were determined with different initial Pb2+ ions concentration (8, 10, 12, 14, and 16 mg.L-1) in the aqueous solution at 298 K, and these results were correlated by using three different isotherm models, for instance, the Langmuir, the Freundlich, and the Temkin. The two-parameter Langmuir model was the best fit to the equilibrium data with a coefficient (R-2) greater than 0.99. The maximum capacities for monolayer adsorption of Mt and Mt-TOA were determined to be 3.37 mg.g(-1) and 33.1 mg.g(-1), respectively, as estimated from Langmuir. Also, experimental values were generated to evaluate the influence of adsorbent amount (w, 0.05-0.3 g for Mt, 0.01-0.06 g for Mt-TOA), starting Pb2+ ion concentration (C-0,8 mg.L-1 to 16 mg.L-1), pH (between 1 and 9), and contact period (t, from 10 to 110 min) on the removal effectiveness and adsorption capability of Mt and Mt-TOA adsorbents. In respect to kinetic studies, the removal efficiency of Pb2+ ion reached to a fixed value of 81.42% with Mt (0.1 g) and 80.67% by Mt-TOA (0.01 g) next 100 and 80 min, respectively. Pseudo-first order, pseudo-second order, and intraparticle diffusion models were studied to obtain the kinetic parameters of the adsorption practice. It is observed that the rate of mass transfer of Pb2+ ions was mainly governed by the intraparticle diffusion mechanism.

    (Amer Chemical Soc, 2019) Uslu, Hasan; Datta, Dipaloy; Santos, Dheiver; Öztürk, Muhsin
    The adsorptive separation of levulinic acid (LA) from its aqueous solution was studied by using a commercial adsorbent and weakly basic anion exchange resin, Amberlite IRA-67 (IRA-67). The data were generated for equilibrium and kinetic studies, and to analyze the performance of IRA-67 on the removal efficiency. The equilibrium study was performed to see the effect of adsorbent quantity (0.25-1.5 g) and initial LA concentrations (2-4 g.L-1) at three different temperatures (298, 308, and 318 K). To determine the kinetics of adsorption process, concentration profile was achieved up to a time of 90 min at 298 K. It was observed that both the intake capacity (32-64 mg.g(-1)) and removal efficiency (6.75-72.5%) of IRA-67 were increased with an increase in the quantity of adsorbent (0.25-1.5 g) at 298 K. From the kinetics of adsorption, 50 min was considered as an equilibrium time. Different isotherm and kinetic models were used to determine the equilibrium and kinetic parameters of LA adsorption process. From the temperature study (298, 308, and 318 K), the thermodynamic properties were also estimated at three different LA concentrations.

    Adsorption of levulinic acid from aqueous solution by Amberlite XAD-4
    (Elsevier Science Bv, 2017) Datta, Dipaloy; Uslu, Hasan
    Levulinic acid (LA) from aqueous solutions was removed by using commercial adsorbent Amberlite XAD-4 (XAD-4). The equilibrium and kinetic studies were performed to investigate the effect of adsorbent amount (1 g to 3.5 g at 298 K, 308 K and 318 K), initial acid concentration (2 g.L-1 to 4 g.L-1 at 298 K, 308 K and 318 K), and contact time (t, 10 min to 90 min at 298 K) on the capability of XAD-4. The uptake capability and removal efficiency of XAD-4 for the adsorption of LA was observed to increase by increasing amount of adsorbent. In the equilibrium experiments of LA adsorption, adsorption capacity value was increased to 26.85 mg.g(-1) from 10 mg.g(-1) at 298 K with an increase in the amount of XAD-4. In the kinetic studies, the equilibrium time of 70 min was obtained. Also equilibrium study was performed at three different temperatures, 298, 308 and 318 K. The maximum removal was obtained at 298 K. Thermodynamic model parameters such as Delta G degrees, Delta H degrees and Delta S degrees are estimated at three different LA concentration (2 g.L-1, 3 g.L-1 and 4 g.L-1). Different isotherm and kinetic models were applied to estimate the equilibrium and kinetic parameters. (C) 2017 Elsevier B.V. All rights reserved.

    Influence of fluorinated extractant aggregation in diluent on extraction of salicylic acid: Evidence from equilibrium, SAXS and molecular dynamics simulation
    (Elsevier Science Inc, 2018) Wu, Xue; Chang, Zhidong; Feng, Jingge; Dang, Hui; Uslu, Hasan; Li, Wenjun
    In order to get optimal extraction performance as well as ultra-low solvent residual, the extraction behavior of tris(2,2,3,3,4,4,4-heptafluorobutyl) phosphate (FTBP) dissolved in 2,3,4,5,6-Pentafluorotoluene (FB) was evaluated to investigate the influence of the aggregation state on the extraction of salicylic acid (SA). The effect of SA distribution and water content on aggregation structure in organic phase was assessed through analysis of SAXS data. Based on molecular dynamic simulation, FTBP tended to aggregate with the existence of FB to accommdate more SA molcules. Water in this case was not the critical factor for aggregation formation due to the hydrophobicity of fluorinated solvents. (C) 2018 The Korean Society of Industrial and Engineering Chemistry.

    Separation of copper ion (Cu2+) from aqueous solution using tri n butyl phosphate and di 2 ethylhexyl phosphoric acid as extractants
    (Elsevier Science Bv, 2018) Ghosh, Amritendu; Datta, Dipaloy; Uslu, Hasan; Bamufleh, Hisham S.; Kumar, Sushil
    In this study, separation of copper ion (Cu2+) from aqueous solution using two phosphorous based extractants (tri n butyl phosphate and di 2 ethylhexyl phosphoric acid) was aimed. The parameters monitored under the equilibrium study were initial copper concentration, extractant concentration, and pH. The copper concentration was taken in the range of 20 to 100 ppm, the extractant composition in the organic phase was varied from 10 to 40 vol% dissolving in toluene as an inactive diluent, and the pH effect was studied in the range of 1 to 11. The distribution coefficients were calculated, and a model equation was developed to estimate model parameters like the number of reacting molecules of the extractant and equilibrium constant using experimental results. In the kinetic study, the initial aqueous phase copper concentration, and the extractant concentration were changed, and initial rates of extraction were found out to develop a kinetic model and their parameters like rate constant and order of reaction.

    Decreasing myocardial estrogen receptors and antioxidant activity may be responsible for increasing ischemia- and reperfusion-induced ventricular arrhythmia in older female rats
    (Pergamon-Elsevier Science Ltd, 2021) Bozdogan, Omer; Bozcaarmutlu, Azra; Kaya, Salih Tunc; Sapmaz, Canan; Ozarslan, Talat Ogulcan; Eksioglu, Didem; Yasar, Selcuk
    Aims: This study aimed to investigate the relationship between ischemia- and reperfusion-induced arrhythmia and blood serum estrogen levels, myocardial estrogen receptor levels, antioxidant enzyme activities, and the effects of the estrogen receptor blocker, fulvestrant (ICI 182 780). Main methods: A total of 102 female Sprague-Dawley rats of different ages (2-3, 6-7, 14-15, and 20-21 months) were used in this study. Myocardial ischemia was produced by ligation of the descending branch of the left anterior descending coronary artery, and reperfusion was produced by releasing this artery. An electrocardiogram (ECG) and blood pressure were recorded for 6 min of ischemia and 6 min of reperfusion. The levels of superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), estrogen receptor alpha (ER alpha), and estrogen receptor beta (ER beta) in myocardial tissue and 17 beta-estradiol (E2) in blood serum were measured via enzyme-linked immunosorbent assay (ELISA). The results were compared using a Mann-Whitney U test, one-way analysis of variance (ANOVA), and a student's t-test. Key findings: It is not the changes in serum estrogen levels but the decreasing myocardial estrogen receptors and antioxidant activities that could be responsible for the occurrence of more severe arrhythmia in response to reperfusion in older female rats. Significance: The death rate due to a heart attack in younger men is higher than in women. However, it equalizes after the menopausal stage in women. In this study, the reason for the increasing sudden post-menopausal death rate in women was investigated experimentally.

    Enhancing the Functionality and shelf life of poppy sherbet by optimizing ultrasound and propolis using response surface methodology: Impact on phenolic compounds, organic acids, sugar components, and sensory characteristics
    (Elsevier, 2025) Akhan, Meryem; Turkol, Melikenur; Yikmis, Seydi; Sancar, Burcu cakmak; Col, Basak Gokce; Khalid, Muhammad Zubair; Moreno, Andres
    Poppy plant, scientifically known as Papaver rhoeas L., is an annual herbaceous wild plant. Propolis boasts numerous health advantages. This study aimed to optimize a novel functional beverage enriched with propolis and enhanced with ultrasound technology using Response Surface Methodology (RSM). Optimization focused on total bioactivities and general acceptability, determining optimal amounts of propolis extract (53.33 mg/100 mL), ultrasound time (7.56 min), and ultrasound amplitude (75.76%) to create the optimized ultrasound-treated propolis poppy sherbet (UTP). The optimized UTP had a high total phenolic content (552.25 mg GAE/L), a DPPH value of 9.26 mu mol trolox/g, a total antioxidant capacity of 42.16 mg Cy-3-gly/mL (Cyanidine-3-glycoside/mL), and a general acceptability score of 7.87. The consistency between experimental results and RSM predictions confirmed the approach's accuracy. After 21 days, bioactive components, phenolic compounds, organic acids, sugars, and sensory properties were assessed. UTP showed enhanced bioactive components and sensory properties compared to standard poppy sherbet, with higher glucose and turanose among 17 phenolic compounds. However, sensory attributes like color, aroma, and taste significantly declined over storage. As a result, these findings contribute to the development of functional beverages and the further enhancement of poppy-related foods using RSM optimization.

    Rehabilitation of Patients With Osteoporotic Fractures
    (Elsevier Science Inc, 2020) Erhan, Belgin; Ataker, Yaprak
    Osteoporosis is a silent, asymptomatic disease until a fragility fracture is sustained. Fractures greatly affect the physical functioning and health-related quality of life and are associated with increased mortality and mor-bidity rates. Furthermore, once a fragility fracture occurs, the patient is more susceptible to sustain further fractures. Repeated falls are the main causes of fractures in patients with osteoporosis. The management of osteoporosis postfracture is a combination of medical treatment, nutritional interventions, and rehabilitation in order to improve activities of daily living to prevent falls and increase safety while reducing the loss of bone mass. In this article the principles of fracture prevention and physical rehabilitation of patients with osteoporosis postvertebral and hip fragility fractures will be discussed, as well as the rehabilitation management to prevent further falls and fractures.

    Enhancement of eye socket recognition performance using inverse histogram fusion images and the Gabor transform
    (Wiley, 2025) Shehu, Harisu Abdullahi; Ince, Ibrahim Furkan; Bulut, Faruk
    The eye socket is a cavity in the skull that encloses the eyeball and its surrounding muscles. It has unique shapes in individuals. This study proposes a new recognition method that relies on the eye socket shape and region. This method involves the utilization of an inverse histogram fusion image to generate Gabor features from the identified eye socket regions. These Gabor features are subsequently transformed into Gabor images and employed for recognition by utilizing both traditional methods and deep-learning models. Four distinct benchmark datasets (Flickr30, BioID, Masked AT & T, and CK+) were used to evaluate the method's performance. These datasets encompass a range of perspectives, including variations in eye shape, covering, and angles. Experimental results and comparative studies indicate that the proposed method achieved a significantly (p<0.001) higher accuracy (average value greater than 92.18%) than that of the relevant identity recognition method and state-of-the-art deep networks (average value less than 78%). We conclude that this improved generalization has significant implications for advancing the methodologies employed for identity recognition.

    Explaining employment and environmental degradation nexus with environmental employment curve (EEC): A sector-wide threshold estimation for China
    (Elsevier Sci Ltd, 2024) Cakmak, Tugba Koyuncu; Beser, Mustafa Kemal; Alola, Andrew Adewale
    China is the world's largest emitter of carbon dioxide and has experienced significant economic growth in the last decade. The country also has significant employment capacity and has witnessed rapid economic growth in the recent years. This study aims to investigate the existence of the environmental employment curve (EEC) in China's main economic sectors. This study examines the relationship between carbon emissions, economic growth, energy consumption, renewable energy consumption and employment (industry, services, agriculture) in China over the period 1990-2020 using threshold autoregressive regression estimation. According to the EEC hypothesis, there exists an inverted U-shaped relationship between environmental pollution and employment rate. Empirical results show that the EEC hypothesis seems to hold in China. Further, an analysis of the impact of employment on environmental pollution in China's three main sectors - industry, service and agriculture - shows that the EEC hypothesis cannot be rejected in the industrial and the agricultural sectors. In addition, empirical results show that a 1% increase in energy consumption leads to a 0.92% increase in carbon emissions, while the use of renewable energy leads to a 0.18% decrease. These results suggest that investments in green energy transformation do not cause employment loss. Hence, it is important to drive policies that promote investments in renewable and clean technologies, stimulate research in renewable energy-related institutions and support public-private partnerships. Additionally, to generate employment without compromising on the environment or prosperity, policymakers should choose to implement alternative technologies that are less polluting or do not produce any carbon emissions.
