Under the background of global climate change and the human activities, the stock of natural capital and the the ability of ecosystem services are facing increasing pressure, and the contradiction between natural capital protection and people’s livelihood development is also increasing. Therefore, it is urgent to integrate ecosystem value estimation into the development decision-making of countries all over the world. As a new ecosystem research method, ecosystem gross product (GEP) accounting is widely used in China, and often used to reflect the effectiveness of regional ecological protection and the coordination relationship between development and protection. We found that : (1) GEP accounting can reflect the overall situation of ecological environment and service quality, and help decision-makers and managers formulate and implement sustainable development strategies and ecological protection policies. (2) The contradiction between the depletion of global ecosystem capital and the development of people’s livelihood continues to intensify. About 68.7% of developing countries facing “low-low development model” (low GEP and low GDP). (3) We have constructed the path model of GEP working system and the path model of ecological protection compensation mechanism in China. The GEP accounting system of “from point to area, from top to bottom”, the parallel evaluation strategy of GDP and GEP and the comprehensive ecological compensation system of “vertical and horizontal combination” implemented can be popularized to countries all over the world.

In the quarry sector, the reduction of landfill material may be obtained not only by finding a suitable recovery of the material as a by-product, but also by identifying the best available cutting technique to be used on the basis of the physical, chemical, and mechanical characteristics of the stones. The choice of the best cutting technique could lead to high efficiency and performance, high quality of the cut surfaces, and a very low environmental impact by reducing energy consumption, decreasing the concentration of heavy metals in the sludge, and producing less waste. In this context, an analysis of the procedures for cutting different types of ornamental stones into slabs together with the evaluation of sludge production for the different cutting methods has been carried out. Two types of analysis were carried out in parallel: evaluation of the stones workability and calculation of the amount of sludge produced in the three different cutting technologies and from the cutting of blocks. A comparison was carried out on the quality of the sludge produced, on type and quantity of metals present, taking into account the different cutting technologies. The performed tests were: chemical analysis, magnetic separation test, and SEM analysis of the metal fraction. The study could provide stone producers with a technological, scientific instrument to identify the best cutting techniques for the processing of their stones, in order to obtain a high-efficiency process, optimize the recovery process, increase the economic advantages, and evaluate the possible reuse of the sludge through a proactive waste management strategy.

AbstractIn order to behave appropriately in a rapidly changing world, individuals must be able to detect when changes occur in that environment. However, at any given moment, there are a multitude of potential changes of behavioral significance that could occur. Here we investigate how knowledge about the space of possible changes affects human change point detection. We used a stochastic auditory change point detection task that allowed model-free and model-based characterization of the decision process people employ. We found that subjects can simultaneously apply distinct timescales of evidence evaluation to the same stream of evidence when there are multiple types of changes possible. Informative cues that specified the nature of the change led to improved accuracy for change point detection through mechanisms involving both the timescales of evidence evaluation and adjustments of decision bounds. These results establish three important capacities of information processing for decision making that any proposed neural mechanism of evidence evaluation must be able to support: the ability to simultaneously employ multiple timescales of evidence evaluation, the ability to rapidly adjust those timescales, and the ability to modify the amount of information required to make a decision in the context of flexible timescales.

S-sulfenylation of cysteine thiols (Cys-SOH) is a regulatory posttranslational modification in redox signaling and an important intermediate to other cysteine chemotypes. Owing to the dual chemical nature of the sulfur in sulfenic acid, both nucleophilic and electrophilic chemical probes have been developed to react with and detect Cys-SOH; however, the efficiency of existing probes has not been evaluated in a side-by-side comparison. Here, we employ small-molecule and protein models of Cys-SOH and compare the chemical probe reactivity. These data clearly show that 1,3-diketone-based nucleophilic probes react more efficiently with sulfenic acid as compared to strained alkene/alkyne electrophilic probes. Kinetic experiments that rigorously address the selectivity of the 1,3-diketone-based probes are also reported. Consideration of these data alongside relative cellular abundance, indicates that biological electrophiles, including cyclic sulfenamides, aldehydes, disulfides and hydrogen peroxide, are not meaningful targets of 1,3-diketone-based nucleophilic probes, which still remain the most viable tools for the bioorthogonal detection of Cys-SOH.

Összefoglaló. Bevezetés: Az állcsonti cysták helytálló diagnosztikája a klinikai, radiológiai és patológiai leletek együttes értékelésével lehetséges. Korábbi munkánk során többször tapasztaltuk a klinikoradiopatológiai kommunikáció és korreláció hiányát, és ez olykor inadekvát diagnózisok felállításához vezetett. Célkitűzés: Célunk ezen kommunikációs probléma mértékének becslése és annak bemutatása, hogy ez a hiányosság hogyan befolyásolhatja a diagnosztikát. Módszer: Korábbi, más célú retrospektív elemzés újraértékelése történt a klinikai (radiológiai) adatközlés, a revízió kapcsán módosuló diagnózisok számszerűsítése céljából, valamint további 3 egyetemi patológiai intézet 10-10 anonimizált leletének vizsgálata az adatközlések vonatkozásában. Eredmények: 2 intézményben 85 odontogen cysta diagnózisakor csupán a betegek életkora, neme volt 100%-osan ismert. A lokalizációra vonatkozó adekvát információ 62%-ban, a méretre vonatkozó csupán 29%-ban fordult elő a szövettani kérőlapokon. Összességében a diagnózist segítő releváns információt csak 52%-ban adtak meg. Az utólagos klinikoradiopatológiai korrelációra törekvő revízió során 38/85 esetben (45%) módosult a végső diagnózis kisebb vagy nagyobb mértékben. A megküldött leletek alapján a klinikai/radiológiai adatok közlése <50% és 100% közöttinek becsülhető más intézetekben is. Az 5 intézmény közül csak az egyikben utalt specializációra az, hogy minden leletet egy patológus véleményezett, általában sok patológus (n = 25) valamelyike véleményezte a kevés tömlőt (n = 105). A diagnózis kommunikáció hiányán alapuló kisiklásának lehetőségét 5 példával illusztráljuk: cysta radicularisként leletezett paradentalis, lobos follicularis és lateralis periodontalis cysta, ductus nasopalatinus cysta és radicularis cysta differenciáldiagnosztikáját példázó tömlő, valamint botryoid odontogen cysta kerül bemutatásra. Következtetés: Az odontogen tömlők precíz diagnosztikája mind a klinikai, mind a patológiai oldalról javítást igényel, amelynek egyik része az ilyen irányú képzés lehet. Orv Hetil. 2021; 162(12): 458–467. Summary. Introduction: Proper diagnosis of jaw cysts requires the parallel evaluation of clinical, radiological and histopathological findings. Lack of clinico-radio-pathological correlation can lead to inconsistent diagnoses. Objective: To evaluate the rate of lacking clinico-pathological communication and demonstrate how this may influence diagnostics. Method: Data of a former retrospective analysis were re-evaluated to quantify the lack of clinical data communicated to pathologists and estimate the rate of final diagnoses requiring alteration after review of all available clinical data. 10 anonymized reports on odontogenic cysts from 3 university pathology departments each were analysed for the lack of relevant clinical information. Results: Only the age and gender of patients were documented in 100% for 85 jaw cysts diagnosed in 2 departments of pathology. Adequate information about cyst localization and size were communicated in 62% and 29%, respectively. Overall, information relevant to the diagnosis was given in 52% of the cases. Revision based on clinico-radio-pathological correlation led to alterations of the diagnosis in 38/85 cases (45%). Based on reports from other institutions, the communication of clinical data is estimated to be between <50% and 100%. 25 pathologists were involved in reporting 105 cysts. 5 cases illustrate how diagnosis may fail without good communication: a paradental, an inflamed dentigerous and a lateral periodontal cyst, each misdiagnosed as radicular cyst; a cyst raising the differential diagnosis of nasopalatine duct versus radicular cyst; a botryoid odontogenic cyst. Conclusion: Proper diagnosis of jaw cysts requires improvements from both pathological and clinical sides, and could probably be improved through education. Orv Hetil. 2021; 162(12): 458–467.

Abstract. TROPOspheric Monitoring Instrument (TROPOMI) near-ultraviolet (near-UV) radiances are used as input to an inversion algorithm that simultaneously retrieves aerosol optical depth (AOD), single-scattering albedo (SSA), and the qualitative UV aerosol index (UVAI). We first present the TROPOMI aerosol algorithm (TropOMAER), an adaptation of the currently operational OMI near-UV (OMAERUV and OMACA) inversion schemes that takes advantage of TROPOMI's unprecedented fine spatial resolution at UV wavelengths and the availability of ancillary aerosol-related information to derive aerosol loading in cloud-free and above-cloud aerosols scenes. TROPOMI-retrieved AOD and SSA products are evaluated by direct comparison to sun-photometer measurements. A parallel evaluation analysis of OMAERUV and TropOMAER aerosol products is carried out to separately identify the effect of improved instrument capabilities and algorithm upgrades. Results show TropOMAER improved levels of agreement with respect to those obtained with the heritage coarser-resolution sensor. OMI and TROPOMI aerosol products are also intercompared at regional daily and monthly temporal scales, as well as globally at monthly and seasonal scales. We then use TropOMAER aerosol retrieval results to discuss the US Northwest and British Columbia 2018 wildfire season, the 2019 biomass burning season in the Amazon Basin, and the unprecedented January 2020 fire season in Australia that injected huge amounts of carbonaceous aerosols in the stratosphere.
