Analysis of pollution removal from wastewater by Ceratophyllum demersum

Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Polluted water is harmful to human health and need to purify. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. Two treatments in four replications for the purpose of purifying wastewater by Ceratophyllum demersum were designed. The treatments included raw municipal wastewater (RMW) and treated municipal wastewater (TMW). The experiment was performed at the open air of Khorasgan University area for 18 days without aeration. Result of the COD indicated that the COD of RMW and TMW were decreased from 664 to 152.75 mg/l and 260 to 64.5 mg/l, respectively. Also, this investigation demonstrated that the amount of ammonium in RMW and TMW decreased from135 to 15 meq/l and 90 to 10 meq/l, respectively. The amount of nitrate in RMW and TMW had a similar decreased from 60 to 30 meq/l as well as 4.48 to 0.53 meq/l, respectively and the amount of phosphorous in RMW and TMW declined from 13.68 to 1.15 meq/l and 4.48 to 0.53 meq/l, respectively. It could be concluded from these results that a significant amount of these macro elements were absorbed by C. demersum. The other factor that was measured in this study was the electrical conductivity (EC). Results of this factor indicated that the EC of treated municipal wastewater (from 1.34 to 0.95 ds/m) and the EC of raw municipal wastewater (from 2.68 to 2.12 ds/m) were reduced. The variation for NH4, NO3, COD and EC were < 5%. Therefore it was concluded that C. demersum can be used for refining wastewater

THE EFFECT OF PROGRESSIVE RESISTANCE TRAINING ON BIOMECHANICS OF ARTHRITIC GAIT: A SINGLE-BLIND RANDOMIZED CONTROL TRIAL

INTRODUCTION: Osteoarthritis (OA) is prevalent in elderly and is associated with muscle weakness. OA progression is related to biomechanical characteristics of gait such as knee adduction moment (KAM). Progressive resistance training (PRT) improves muscle strength in this population, but PRT effects on biomechanics of gait related to OA progression are unknown. We hypothesized that PRT would reduce KAM, mediated by improvements in the strength of all lower limb muscle groups

GAIT AND POSTURE IN ARTHRITIC AND HEALTHY KNEES

INTRODUCTION: The gait characteristics of patients with OA of the knee have been wellstudied and reported; however, less attention has been paid to the postural differences between OA affected and healthy knees. The aim of this study was to investigate the postural differences that may affect the gait in an OA group compared to the controls

Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling

Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmon and a polariton mode which enables an improved quantum non-demolition (QND) readout for superconducting qubits. The new mechanism uses the same experimental techniques as the standard QND qubit readout in the dispersive approximation, but due to its non-perturbative nature, it maximizes the speed, the single-shot fidelity and the QND properties of the readout. In addition, it minimizes the effect of unwanted decay channels such as the Purcell effect. We observed a single-shot readout fidelity of 97.4% for short 50 ns pulses, and we quantified a QND-ness of 99% for long measurement pulses with repeated single-shot readouts

The Immediate Effect of Lateral Wedge Insoles, With and Without a Subtalar Strap, on the Lateral Trunk Lean Motion in Patients With Knee Osteoarthritis

Background: Orthotic interventions for knee osteoarthritis (OA) aim to reduce mechanical loading on the medial compartment of the knee and may lessen the lateral trunk lean as the most important compensatory gait strategy. The lateral wedge insole is a known orthotic intervention for knee OA. However, the question whether the addition of a subtalar strap to the wedge improves its effect has not been addressed in the literature. Objective: To compare the effects of lateral wedge insoles, with and without a subtalar strap, on the lateral trunk lean in patients with knee OA. Methods: Twenty-three patients aged over 40 years, with grade I or II OA of the medial compartment of one knee, based on the American College of Rheumatology criteria, were included in this study. The patients were diagnosed with OA based on a clinical examination, and the diagnosis was confirmed with radiographs. A 3-dimensional motion measurement system was used to collect the gait data for 3 different conditions: (1) with no insole, (2) with a lateral wedge insole, and (3) with a lateral wedge insole and a subtalar strap. The immediate effect of the 3 test conditions on the lateral trunk lean was compared during a gait cycle a stance phase and at the point of midstance. Results: Based on the laboratory coordinate system, the 3 conditions had no significant effect on the lateral trunk lean during a gait cycle and a stance phase and at the point of midstance in patients with knee OA. Conclusion: The results of this study demonstrated that the lateral wedge insoles, with and without a subtalar strap, had no immediate effect on the lateral trunk lean in patients with knee OA. However, the long-term effect of lateral wedge insoles on the lateral trunk lean in these patients requires further investigation. © The Author(s) 2013

Qubit readout using in-situ bifurcation of a nonlinear dissipative polariton in the mesoscopic regime

We explore the nonlinear response to a strong drive of polaritonic meters for superconducting qubit state readout. The two polaritonic meters result from the strong hybridization between a bosonic mode of a 3D microwave cavity and an anharmonic ancilla mode of the superconducting circuit. Both polaritons inherit a self-Kerr nonlinearity $U$, and decay rate $\kappa$ from the ancilla and cavity, respectively. They are coupled to a transmon qubit via a non-perturbative cross-Kerr coupling resulting in a large cavity pull $2\chi > \kappa, ~U$. By applying magnitic flux, the ancilla mode frequency varies modifying the hybridization conditions and thus the properties of the readout polariton modes. Using this, the hybridisation is tuned in the mesoscopic regime of the non-linear dissipative polariton where the self-Kerr and decay rates of one polariton are similar $U\sim \kappa$ leading to bistability and bifurcation behavior at small photon number. This bistability and bifurcation behavior depends on the qubit state and we report qubit state readout in a latching-like manner thanks to the bifurcation of the upper polariton. Without any external quantum-limited amplifier, we obtain a single-shot fidelity of $98.6\%$ in a $500$ ns integration time

Abdominal volume index: A predictive measure in relationship between depression/anxiety and obesity

Background: Obesity is a risk factor for mood disorder (such as depression and anxiety). We aimed to assess application of A Body Shape Index (ABSI) and abdominal volume index (AVI), as new indices of obesity to evaluate the relationship between obesity and depression/anxiety. Methods: This cross sectional study was conducted on 307 overweight and obese women (249 females, 58 males) 20-60 years in Iran in 2017-2018. The anthropometric measures including weight, waist circumference, hip circumference, body fat and derived values of body mass index, waist�hip ratio, AVI and ABSI were evaluated. HADS questionnaire for depression and anxiety completed. Results: Prevalence of depression was 36.1 in women; men 24.1; overweight 28.1; obese 36.5 and central obesity 33.7. Anxiety was apparent in 27.1 of overweight 30.3 obese and 29.6 central obesity. People with depression and anxiety had higher WC, BF and AVI. ABSI had no significant correlation with depression/anxiety. The odds of depression (1.06; 95 CI, 1.02-1.12) and anxiety (1.06; 95 CI, 1.01-1.11) were elevated with increase AVI. Conclusion: Our results suggested that AVI as an indirect measure of abdominal obesity along with WC and BF could be useful in predicting the relationship between obesity and depression/anxiety. © 2020 Hadi S et al.
