The pharmaceutical industry spends billions of dollars every year for marketing its products to US health care providers. This study investigates the association between industry marketing payments and physicians' prescription in New York and Massachusetts, and examines the effect of the Massachusetts payment restriction policy on this association in comparison with the New York State that has no payment restriction policy. Three panel data models (fixed effects regression (FE), first difference regression (FD), and first difference with lagged independent variable (LFD)) were used to establish the association accounting for unobserved confounders and reverse causality. The main indicator is the total amount of industry payments for meals, drug samples, consulting fees, etc. (excluding research funding, and ownership). Dependent variables are a) yearly days' supply of Medicare Part D prescriptions, b) yearly costs of prescribed prescriptions. Secular time trends, as well as differences between the two states ation, which calls for further research.Ensuring food security in an environmentally sustainable way is a global challenge. Epacadostat To achieve this agriculture productivity requires increasing by 70 % under increasingly harsh climatic conditions without further damaging the environmental quality (e.g. reduced use of agrochemicals). Most governmental and inter-governmental agencies have highlighted the need for alternative approaches that harness natural resource to address this. Use of beneficial phytomicrobiome, (i.e. microbes intimately associated with plant tissues) is considered as one of the viable solutions to meet the twin challenges of food security and environmental sustainability. A diverse number of important microbes are found in various parts of the plant, i.e. root, shoot, leaf, seed, and flower, which play significant roles in plant health, development and productivity, and could contribute directly to improving the quality and quantity of food production. The phytomicrobiome can also increase productivity via increased resource use efficiency and resilience to biotic and abiotic stresses. In this article, we explore the role of phytomicrobiome in plant health and how functional properties of microbiome can be harnessed to increase agricultural productivity in environmental-friendly approaches. However, significant technical and translation challenges remain such as inconsistency in efficacy of microbial products in field conditions and a lack of tools to manipulate microbiome in situ. We propose pathways that require a system-based approach to realize the potential to phytomicrobiome in contributing towards food security. We suggest if these technical and translation constraints could be systematically addressed, phytomicrobiome can significantly contribute towards the sustainable increase in agriculture productivity and food security.Turbidity is an indication of water quality and enables the growth of pathogenic microorganisms. For drinking water treatment plants (DWTPs), violent fluctuations in turbidity are highly disruptive to operational performance due to the lag in process parameter adjustments. Such risks must be carefully managed to guarantee safe drinking water. Machine learning techniques have been proven to be effective for modeling complex nonlinear environmental systems, and this study adopted such a technique to develop a model for predicting source water turbidity for DWTPs to allow DWTPs to make proactive interventions in advance. A random forest (RF) model used preprocessed (empirical mode decomposition and quartile rejecting) meteorological factors (wind speed, wind direction, air temperature, and rainfall) as the input variables, to establish the turbidity prediction of a lake with significant turbidity in China's South Tai Lake. The modeling process included four main stages (1) source data analysis, (2) raw data preprocessing, (3) modeling and tuning, and (4) model evaluation. The results of the RF model indicated that the correlation coefficient between the predicted and actual sequences is over 0.7, and more than 55% of the predicted values could control the errors within 20% compared to the actual measured values, suggesting that machine learning techniques are suitable for predicting the turbidity of raw source water. It was found that the RF model can provide a modest performance boost because of its stronger capacity to capture nonlinear interactions in the data. The findings of this study can inform the development of turbidity prediction models using readily available meteorological forecast data. The model can be applied to other DWTPs using similar shallow lakes as water sources.In this research, magnetic MgFe2O4-CaFe2O4 photocatalyst powder was prepared from recycling of electric arc furnace (EAF) dust as a secondary source through a two-step leaching process followed by co-precipitation method. To maximize the total Fe to Ca recovery ratio (F/C) and evaluate the effective parameters of sulfuric acid concentration and temperature, response surface methodology (RSM) as a design of experiment was used. The best temperature and acid concentration were obtained as 85 °C and 1 M, respectively for the second step of the leaching process. X-ray diffraction (XRD) results indicated that the synthesized nanocomposite sample contains MgFe2O4 and CaFe2O4 phases together with a small amount of Ca2Fe2O5. The saturation magnetization and optical band gap of the synthesized composite powder were 24 emu/g and 2.17 eV, respectively. X-Ray photoelectron spectroscopy (XPS) result revealed the oxidation states as Fe3+, Ca2+, Mg2+ and O2-. Energy dispersive X-ray spectroscopy (EDS) showed that the elements were uniformly distributed within the nanostructured particles. Field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM) results indicated the presence of CaFe2O4 and MgFe2O4 nanoparticles with good contact between them. The nanocomposite sample showed the capability of 45% for degrading methylene blue (MB) dye under 240 min visible light irradiation. The reusability tests showed that the photocatalytic activity of the nanocomposite was not considerably changed after three cycles.
