The physicochemical treatment (PT) of food industry wastewater was investigated. In the first stage, calcium magnesium acetate (CaMgAc4) was synthesized using eggshell (biocalcium), magnesium oxide and acetic acid in a 111 stoichiometric ratio. In the synthesis process, the thermodynamic parameters (ΔH, ΔS and ΔG) indicated that the reaction was endothermic and spontaneous. The samples were characterized by infrared spectroscopy (IR), scanning electronic microscopy (SEM), X-ray diffraction (XRD) and electron X-ray dispersive spectroscopy (EDS). CaMgAc4 was used to precipitate the phosphate matter. IR analysis revealed that the main functional groups were representative of the acetate compounds and the presence of OH- groups and carbonates. In the physicochemical treatment, a response surface design was used to determine the variables that influence the process (pH, t, and concentration), and the response variable was phosphorus removal. The treatments were carried out in the wastewater industry with an initial concentration of 658 mg/L TP. The optimal conditions of the precipitation treatment were pH 12, time 12 min, and a CaMgAc4 concentration of 13.18 mg/L. These conditions allowed the total elimination (100%) of total phosphorus and phosphates, 81.43% BOD5 and 81.0% COD, 98.9% turbidity, 95.01% color, and 92% nitrogen matter.In this study, graphene oxide and composites of graphene oxide-iron modified clinoptilolite were synthesized and used for arsenate removal from aqueous solution. All adsorbents were characterized using X-ray diffraction and specific surface area analysis. The specific surface areas of composites were found to be less than the iron modified clinoptilolite. The time required to reach equilibrium was determined as 3 hours for all adsorbents. The Box-Behnken statistical experiment design method was used to determine the effects of initial arsenate concentration, pH and the amount of adsorbent on the percent arsenate removal. Graphene oxide was not as effective as composites for arsenate adsorption from water. Arsenate adsorption on composites was showed good compatibility with the Freundlich isotherm. The maximum arsenate uptake was realized at pH 4 for graphene oxide and at pH 7 for composites. The maximum adsorption capacities obtained at the optimum points determined by using the Box-Behnken design method were calculated as 39.49, 117.98 and 124.64 µg.g-1 for graphene oxide and composites, respectively.

Non-vitamin K antagonist oral anticoagulants (NOACs) are used to treat acute pulmonary embolism (PE). However, lower NOAC doses are often prescribed because of increased risk of NOAC complications.

We sought to determine the incidence and clinical outcomes of patients with acute provoked PE receiving lower NOAC doses.

140 patients with acute PE with only NOACs used for medical management was enrolled and were followed up for 6 months. The composite primary endpoint was all-cause death, venous thromboembolism recurrence, and residual thrombus on follow-up computed tomography.

Of the 140 patients, 99 (70.7%) received the standard NOAC dose and 41 (29.3%) received the lower dose. The crude incidences of the primary endpoint were 19 (19.2%) in patients who received the standard NOAC dose and 13 (31.7%) in those who received the lower dose. Compared with patients who received the standard dose, those who received the lower dose had no differences in the rate of primary endpoints (hazard ratio 1.140, 95% confidence interval 0.536-2.423,

 = 0.733) during a median of 185 days.

We found that up to 30% of patients received the lower dose of NOACs for acute PE in clinical practice. Clinical outcomes with appropriate underdoing of NOAC treated in acute PE might not increase compared to the standard NOAC doses.

Telehealth methods may provide a solution, however evidence supporting the efficacy of remotely-delivered therapy is needed. A non-concurrent multiple baseline design was used with randomized onset of intervention across five individuals with chronic stroke-related memory complaints. A six-week compensatory memory skills programme was delivered individually via internet videoconferencing. Target behaviours of frequencies of self-reported lapses of everyday and prospective memory were measured weekly across baseline, intervention, and follow-up phases. A secondary outcome of functional goal attainment was measured once per phase, with participants setting two personal rehabilitation goals. Data were analysed visually and statistically. Improvements in memory functioning were statistically significant on at least one measure of target behaviour for four out of five participants at intervention or follow-up. Visual evidence of level change indicated at least modest improvements for all participants by follow-up. All participants attained at least one functional goal by follow-up. High rates of treatment adherence and participant satisfaction were observed. Technological issues were minimal and did not impact content delivery or engagement. These results provide preliminary support for the efficacy of a telehealth-delivered rehabilitation programme in improving memory function and achieving memory-related goals for stroke survivors.The aim of this study was to compare the distribution of activation among the three heads of the hamstring between a knee flexion-oriented exercise (Nordic hamstring) and a hip extension-oriented exercise (stiff-leg Deadlift) at the group and individual level. selleck inhibitor Data were collected for 20 participants. Muscle activation of the semimembranosus (SM), semitendinosus (ST), and biceps femoris (BF) was estimated using surface electromyography (EMG) during Nordic hamstring and stiff-leg Deadlift exercises. Although Nordic hamstring exercise induced a higher normalized RMS EMG value for BF (64.5 ± 17.4%) compared to SM (48.6 ± 14.6%; P less then 0.001) and ST (55.9 ± 17.4%; P less then 0.001), the greatest active muscle varied between individuals. Similar interindividual differences in the greatest active muscle were found for the stiff-leg Deadlift exercise. Regarding the distribution of activation, the stiff-leg Deadlift favoured the contribution of the SM compared to ST (P less then 0.001, 18/20 participants) whereas the Nordic hamstring exercise favoured the contribution of the ST compared to SM (P less then 0.
