Highly Defective UiO-66 Materials for the Adsorptive Removal of Perfluorooctanesulfonate

Perfluorooctanesulfonate (PFOS) is a persistent organic pollutant that is bioaccumulative and toxic. While its use in most countries has been restricted to certain industrial applications due to environmental and health concerns, chrome plating and semiconductor manufacturing facilities are industrial point sources of PFOS-containing wastewater. Current remediation technologies are ineffective at treating these highly concentrated industrial effluents. In this work, UiO-66 metal–organic frameworks (MOFs) of several defect concentrations were studied as sorbents for the removal of PFOS from concentrated aqueous solutions. PFOS sorption isotherms indicated that defective UiO-66, prepared with HCl as a modulator, had a maximum Langmuir sorption capacity of 1.24 mmol/g, which was ∼2× greater than powdered activated carbon (PAC), but ∼2× less than that of a commercial ion-exchange resin. Defective UiO-66 adsorbed PFOS 2 orders of magnitude faster than the ion-exchange resin. Large pore defects (∼16 and ∼20 A) .
Photo-Activated Sludge: A Novel Algal-Bacterial Biotreatment for Nitrogen Removal from Wastewater

Nitrogen rich wastewaters (10-400 mg N L-1) are usually produced by municipal, industrial and agricultural wastes, such as effluents from anaerobic treatments. These represent a risk to the environment due to the high nutrient concentrations (nitrogen and phosphorous), which can cause eutrophication of water bodies, deteriorating the quality of the ecosystems. As a solution, the potential nitrogen removal capacity of a novel bio-treatment system, namely the Photo-Activated Sludge (PAS), composed of microalgae and bacteria consortia, was studied.
Effect of Sunny/Shady Slopes on Phases
of Precipitation in China’s Tianshan Mountains

Precipitation is an important element in the hydrological cycle in mountainous regions. Temporal and spatial variations in precipitation and in its two phases – rain and snow – over the northern and southern aspects of the slopes of the Tianshan Mountains are compared and analyzed using 55-year data (1961-2015). The results of the analysis are as follows: 1) The average annual precipitation shows an upward trend: rainfall on the northern slopes increase by 6.7 mm per decade and that on the southern slopes by 6.4 mm per decade; the corresponding figures for snow are 2.0 mm and 4.2 mm; and the ratio of snowfall to precipitation (S/P) showed a weak decreasing trend on both the slopes. 1) At a confidence level of 0.05, the M-K test shows that rain, snow, and S/P increased after the change point, while rain and snow change significantly in the proportions,but S/P does not. 2) On the northern slopes, the periodicity of major changes is 25 years for rain and 30 years for snow, whereas on the southern slopes the pattern is the exact opposite, the periodicity of major changes being 25 years for rain and 30 years for snow.
BIOINDICATION OF CHEMICAL ELEMENTS DEPOSITION IN THE HIGH TATRA MTS (SLOVAKIA) BASED ON CALLUNA VULGARIS (L.) HULL; COMPARATIVE LEVELS AFTER THE IMPROVEMENT OF EMISSIONS

Calluna vulgaris was collected on the south slope of Lomnicky stit peak in Skalnata dolina valley (The High Tatra Mts) between 1987 1988 and repeat sampling took place in 2011, following reduction of emissions. Cu, Cd, Zn, Pb, Cr, Mn, Mo, Fe, S and F concentrations were determined in the samples. The results of ordination analysis and correlation analysis show a positive significant correlation of Pb, Fe and Cu (r=0.6320-0.9519) with rising altitude and negative significant correlation of S (r=0.7398). Due to reduced emissions the sulphur correlation with rising altitude became positive not significant in 2011. In 1987-1988, Mo, Mn, Cr, Cd and Zn did not show any significant correlations with altitude. In 2011, Fe, Mo, Cr, Zn and Mn also showed no significant correlation with altitude. Pb and Cu retained a positive significant correlation with rising altitude. There was a significant change correlated to sulphur. In 1987-1988 the highest sulphur concentrations had been recorded up to 1300 m a.s. l. (>109.8 mg.100g(-1)), whereas in 2011, the lowest sulphur concentrations were recorded at these altitudes (<87 mg.100g(-1)) due to reduction of emissions. In 2011, data on fluorine has not been recorded. Despite the reduction of emissions, the accumulated heavy metals remain in the ecosystem for a long time and acceptable concentrations are mostly exceeded, approximately 2-4 times, in the case of chromium up to 10 times.

It often requires a multidimensional perspective. There are different evaluation methods applicable to different kinds of products, depending on the focus and the effects that such application has on the business. This paper proposes a hybrid multidimensional evaluation method that takes into account four concern dimensions: Business, Architecture, Process and Organization [BAPO].
Subcellular calcium patterns in ventricular myocytes

Understanding the biology and mechanisms as to how the heart contracts has long been a point of interest for biologists and mathematicians alike. Since inconsistent beating of the heart has been linked to multiple pathological conditions, research into this area has been extensive but we still only have some of the answers. One of the key findings over the last century has been the role of calcium in activating the machinery within the heart that drives contraction. Further studies have shown that when calcium is mishandled by the heart's myocytes, it can lead to some of these pathological conditions. Since such discoveries a major point of research into the heart has focused on the possible avenues that calcium mishandling can occur. This thesis explores some of these avenues using a mathematical model of the ventricular myocyte developed by Thul and Coombes in their 2010 paper 'Understanding cardiac alternans: A piecewise linear modeling framework'. The chosen model contains key components involved in the movement of calcium within the myocyte. Moreover, the model used is piecewise linear and the stability of some important behaviours can be studied exactly without the need for approximations and reductions. This is often an issue in many other models used to study the calcium dynamics within a ventricular myocyte. The avenue towards calcium mishandling that this thesis predominantly focuses on is that of intracellular calcium diffusion between the building blocks of ventricular myocytes known as sarcomeres. Our research extends previous research into how strong diffusion between sarcomeres can cause unwanted calcium dynamics. Further to this, we explore how the balance in the strength of different forms of calcium diffusion between sarcomeres can drive a variety of spatial patterns in terms of how the calcium is distributed throughout the cell. Throughout these studies we also investigate the role of other parts of the myocyte, particularly the sarcoplasmic reticulum Calcium-ATPase pumps and sarcoplasmic reticulum release in relation to diffusion driven instabilities. As well as intracellular diffusion of calcium, this thesis considers the role of intercellular diffusion of calcium through gap junctions. This form of diffusion has historically been considered to a lesser extent than intracellular diffusion. As such this thesis introduces new ideas concerning gap junctions. These include a role in driving the mishandling of calcium as well as altering behaviours driven by intracellular diffusion. An important message is that calcium diffusion within the myocyte is far more important in terms of how unwanted behaviours can appear than previous studies suggest.
HDL cholesterol and mortality in Finnish men with special reference to alcohol intake.

BACKGROUNDThere is substantial evidence that a low serum level of HDL cholesterol (HDLC) is a risk factor for coronary deaths. However, data on older people are scarce, and previous studies have not examined this association in relation to alcohol intake.METHODS AND RESULTSCoronary mortality, all-cause mortality, and mortality due to alcohol and violence were related to HDLC levels among 7052 male smokers 50 to 69 years old in south and west Finland enrolled from 1984 to 1988 in the ATBC (AT, alpha-tocopherol; BC, beta-carotene) Study placebo group. During the average follow-up period of 4.7 years, 620 men died; 222 of these deaths were from coronary heart disease and 82 from causes related alcohol and violence. HDLC levels were inversely associated with coronary mortality, irrespective of age, whereas high total cholesterol was positively associated with coronary mortality among the younger men, 50 to 59 years of age, but not among the older men, 60 to 69 years old. Correction for temporal variation in H.
Classical theory for second-harmonic generation from metallic nanoparticles. Phys Rev B 79:235109

In this paper, we develop a classical electrodynamic theory to study the optical nonlinearities of metallic nanoparticles. The quasi free electrons inside the metal are approximated as a classical Coulomb-interacting electron gas, and their motion under the excitation of an external electromagnetic field is described by the plasma equations. This theory is further tailored to study second-harmonic generation. Through detailed experiment-theory comparisons, we validate this classical theory as well as the associated numerical algorithm. It is demonstrated that our theory not only provides qualitative agreement with experiments but it also reproduces the overall strength of the experimentally observed second-harmonic signals.
Analysis of rare and endemic flora in northeastern Algeria: the case of the wilaya of Souk Ahras

Scarcity and endemism are considered the most important concepts of a region’s biodiversity and conservation. Nevertheless, our understanding of the models of scarcity and endemism is limited to high biodiversity regions as, for example, the wilaya of Souk Ahras, northeastern Algeria. In this study, we have compiled a list of all heritage species, their taxonomic composition, and geographic distribution. A total of 119 species was documented, and their distribution was as analyzed in the biological environments of two distinct phytogeographic sectors — C1 and H2. The rate of scarcity and endemism increased alongside the organic matter richness and, as a result, the forest and pre-forest area supported an over-representation of these species. The preservation of this biodiversity, exceptional and threatened, urgently requires appropriate scientific studies and environmental protection as short term measures.
The Influence of Storage of Pawpaw Carica papaya Fruit on the Bioactive Components, Antioxidative Properties and Inhibition of Fe2+-Induced Lipid Peroxidation of Water-Extracts of Pawpaw Seed

Freshly harvested, matured, newly ripe pawpaw (Carica papaya) fruit (Maradol variety) wasstored at room temperature (27±1 °C) for 7days. The seeds of the freshly harvested and stored pawpawfruit were taken and divided into two groups each; one was dried as dry sample, dry freshly harvestedsample (DFHS) and dry stored sample (DSS) while the other was left as wet sample, wet freshly harvestedsample (WFHS) and wet stored sample (WSS). The bioactive components, antioxidative properties andinhibition of Fe2+ induced lipid peroxidation activity of the water extract of the seed were investigated.Storage of pawpaw fruit caused a significant increase in ascorbic acid and flavonoid content of the pawpawseed in both dry and wet samples but only in dry stored sample significant increase in the phenol contentof the seed was observed. The dried pawpaw seed DFHS and DSS showed stronger inhibition of Fe2+induced lipid peroxidation activities.
Brain and tissue distribution of polyethylene glycol-conjugated superoxide dismutase in rats.

The purpose of this study was to determine the distribution of polyethylene glycol-conjugated superoxide dismutase in the brain, cerebrospinal fluid, and various organs.Distribution of iodine-125-labeled polyethylene glycol-conjugated superoxide dismutase was determined in three groups of male Sprague-Dawley rats: a normotensive sham control group (n = 9) and groups given 125I-labeled polyethylene glycol-conjugated superoxide dismutase either 30 minutes before (n = 10) or 30 minutes after (n = 7) norepinephrine-induced hypertensive injury.In the first 30 minutes after intravenous administration, polyethylene glycol-conjugated superoxide dismutase plasma activity declined to 70% of the initial value and then decreased negligibly between 30 and 90 minutes. Levels of 125I-labeled polyethylene glycol-conjugated superoxide dismutase in normotensive animals were low in the brain and cerebrospinal fluid and highest in kidney. Brain levels of polyethylene glycol-conjugated superoxide dismutase were elevated only .

The aim of the Thesis is to test the angle of repose in a laboratory for architectural building stone and mining machinery using the lifting cylinder method on four different samples (quartz sand, river gravel, marble and dolomite). The formed heap is photographed from several positions, the photos are uploaded into the "Agisoft PhotoScan" program, and three-dimensional models of the heap are obtained. The three-dimensional models were used to determine the values of angle of repose and the influence of grain size on the angle of repose of granular material.
In Vitro Characterizations of Si4+ and Zn2+ Doped Plasma Sprayed Hydroxyapatite Coatings Using Osteoblast and Osteoclast Coculture.

Osteoporosis is one of the most commonly identified bone disorders, which leads to an enhanced risk of bone fracture, especially for the older population. Hydroxyapatite (HA) coated titanium (Ti) alloys have been used widespread for load bearing applications like hip or knee replacements owing to their compositional similarity to natural bone; however, incorporation of osteoinductivity is still a challenge. The objective of this study is to evaluate the effects of SiO2 and ZnO as dopants in HA coated Ti alloys on cellular osteoporotic conditions mimicked by an in vitro osteoblast and osteoclast coculture model. HA, Si-HA, and Zn-HA coatings showed adhesive bond strengths of 25.7 ± 1.9 MPa, 23.8 ± 2.3 MPa, and 22.9 ± 3.5 MPa, respectively. To study the effects of doped HA coatings on the simulated osteoporotic cellular condition, human mesenchymal stem cells (hMSCs) and monocytes (THP-1) were seeded simultaneously in a ratio of 1:4, respectively. Gene expressions studies were carried out with marker genes showing that the presence of the dopants in the HA coating enhanced osteoblast proliferation along with diminishing cell growth of osteoclasts. This study demonstrates the promising effects of SiO2 and ZnO in plasma sprayed HA coatings on alleviating osteoporosis cellular conditions, which can potentially be used for load-bearing implants in aging patients whose bone resorption is more dominant than bone formation.
Carbon Allowance Allocation on Chinese Industrial
Sectors in 2030 under Multiple Indicators

Aiming at China’s “2030 target,” and given the key role of industrial sectors in CO2 emission reduction, this paper selects the path of allocating carbon emission allowance among different industrial sectors. By selecting CO2 accumulation emissions, the industry-added value and the CO2 emission efficiency which is calculated by the super-SBM model, a carbon intensity distribution model has been established for the allocation. Considering the different preferences of policymakers, different weights are used, meanwhile, an entropy weighting method is proposed to make a contrast. The main conclusions of this paper are: 1) The tendency of decision makers to assign principles has a great impact on the distribution of responsibility for the industry’s emission reduction responsibilities. 2) CO2 emission intensity and carbon dioxide emission efficiency of various industries in China are very different, which is mainly related to the energy consumption demand, input, and output of various industries. 3) More historical accumulated emission and carbon intensity will shoulder more intensity reduction burden, and the industrial sector with the heaviest reduction burdens are those with the two high indicators, regardless of the tendency of decision makers.
Inelastic Scattering of N2 off W(001): Reconciling Experiment and Theory at Low Collision Energies

The inelastic scattering dynamics of N2 off W(001) has recently been the subject of theoretical investigations, which were found to be unable to describe low-collision-energy molecular beam experiments. This discrepancy was suggested to originate from the neglect of van der Waals interactions in the construction of the potential energy surface. By making use of a newly developed potential energy surface, accounting for such dispersion interactions, we show that quasi-classical dynamics simulations, including dissipation to surface electrons and phonons, lead to an adequate description of the low-collision-energy experiments and, more specifically, the trapping-desorption component of inelastic scattering. This work highlights the prominent influence of van der Waals forces on gas–surface dynamics observables in the low-collision-energy regime.
Critical events leading to cellular mortality of yeast cells following hydrostatic pressure treatment

ABSTRACT Hydrostatic pressures of 40–150 MPa are sub-lethal conditions for yeast cells. On exposure to this pressure range, damaged yeast cells will attempt to recover, but a critical cellular event may ultimately lead to cell mortality. We employed yeast strains whose cellular organelles were labeled with green fluorescent protein to investigate this critical event. We were able to visualize the nuclear membrane, nucleus, endoplasmic reticulum, Golgi body, and plasma membranes. Of the cellular organelles tested, the nuclear membrane was the weakest, displaying damage following only 50 MPa of pressure. This nuclear membrane rupture correlated with cellular viability. Thus, we hypothesize that nuclear membrane damage is the critical event leading to cellular mortality of yeast cells following hydrostatic pressure treatment.

Thermal conductivity anomaly in spin-crossover ferropericlase under lower mantle conditions and implications for heat flow across the core-mantle boundary

Abstract Iron in ferropericlase experiences a spin crossover from a high spin to a low spin under lower mantle conditions, which generates anomalies in many properties such as the heat capacity and sound velocity. In this study, the effect of the spin crossover on thermal conductivity was evaluated by considering the effects of the spin crossover on P wave velocity and heat capacity at constant volume but ignoring the effect on the mean free path. The spin crossover completely changes the conventional pressure and temperature dependences of the thermal conductivity. The spin crossover can significantly reduce the thermal conductivity of ferropericlase. The pressure dependence of the thermal conductivity of ferropericlase will show a double-valley feature across the spin-crossover region at the appropriate temperature (e.g., 1000 K). In contrast to the conventional decrease in the thermal conductivity with temperature, the thermal conductivity of ferropericlase in the Earth’s D″ layer may increase with temperature in some temperature regions. The unusual effect of spin crossover on the thermal conductivity can be expected in other minerals with spin crossover. The spin crossover effect needs serious consideration when estimating the thermal conductivity at the core-mantle boundary.
