Challenges and opportunities for citrus wastewater management and valorisation: A review.
2022
Citrus wastewaters (CWWs) are by-products of the citrus fruit transformation process. Currently, more than 700 million of m³ of CWWs per year are produced worldwide. Until nowadays, the management of CWWs is based on a take-make-use-dispose model. Indeed, after being produced within a citrus processing industry, CWWs are subjected to treatment and then discharged into the environment. Now, the European Union is pushing towards a take-make-use-reuse management model, which suggests to provide for the minimization of residual pollutants simultaneously with their exploitation through a biorefinery concept. Indeed, the recovery of energy nutrients and other value-added products held by CWWs may…
Fossil Fuel and Biofuel Boilers in Ukraine: Trends of Changes in Levelized Cost of Heat
2022
An increase in the share of renewables in heat supply systems is a promising direction to reach sustainable development goals and decarbonization. Decision makers should consider various factors, including energy market prices, the availability of biofuels, boiler and auxiliary equipment costs, logistic costs, and the taxation system. In the European Union, the energy crisis causes a rapid increase in fossil fuel prices. Moreover, the use of fossil fuels results in greenhouse gas emissions, which threatens the achievement of sustainable development goals. We studied the influence of the delivery cost and the value of environmental tax rates on the levelized cost of heat. Low-capacity boiler…
CT coronary angiography at an ultra-low radiation dose (< 0.1 mSv): feasible and viable in times of constraint on healthcare costs
2013
Computed tomography coronary angiography (CTCA) has reached very high standards both in terms of diagnostic performance and radiation dose reduction. This commentary follows a report on CTCA using less than 0.1 mSv in selected patients. This is an extraordinary accomplishment, both for technology and for medicine. The difficult task is now to implement this tool in clinical practice so it can play the best possible role. CTCA can improve diagnostic pathways, can save money for healthcare systems and could even improve pharmacological therapy. All of this may happen, but it will require the combined effort of all the experienced operators in this field, including the referring clinicians. In…
Communist Authorities Contra Brother Kloc. The Battlefront Against The Illegal Trade of Devotional Items in The Koźle District In 1965
2019
W artykule przedstawiony został casus jednego z zakonników Kościoła Katolickiego. Zdaniem autora przypadek ten dobrze ilustruje realia, w jakich przyszło żyć duchowieństwu w Polskiej Rzeczypospolitej Ludowej. Wojciech Kloc, ze Zgromadzenia Braci Albertynów, prowadził handel dewocjonaliami w celu zarobienia pieniędzy na remont dachu domu zakonnego. Z tego powodu został zatrzymany przez milicję przed jednym z kościołów w Kędzierzynie (powiat kozielski), gdzie odebrano mu dewocjonalia, którymi handlował oraz pieniądze, które przy nim znaleziono. Czyn, którego się dopuścił zakonnik, został zakwalifikowany jako przestępstwo w świetle ustawy z 1958 r. o zezwoleniach na wykonywanie przemysłu, rzem…
Graduate employment and the returns to higher education in Africa
2013
http://cemapre.iseg.utl.pt/educonf/2e3/files/submissions_to_web/Barounia%20Mahdi_Broeckeb%20%20Stijn.docx; In this paper, we estimate the return to higher education for 12 African countries using recent data and a variety of methods. Importantly, one of our methods adjusts for the effect of higher education on the rate of joblessness, which is substantial in most African countries, and particularly for women. Our results confirm that Mincerian coefficients cannot be interpreted as a true rate of return, and that the latter (even after taking into account the employment effect) is considerably lower than what has previously been suggested in the literature (less than half). For Sub-Saharan A…
High Order Compact Finite Difference Schemes for A Nonlinear Black-Scholes Equation
2001
A nonlinear Black-Scholes equation which models transaction costs arising in the hedging of portfolios is discretized semi-implicitly using high order compact finite difference schemes. A new compact scheme, generalizing the compact schemes of Rigal [29], is derived and proved to be unconditionally stable and non-oscillatory. The numerical results are compared to standard finite difference schemes. It turns out that the compact schemes have very satisfying stability and non-oscillatory properties and are generally more efficient than the considered classical schemes.
Therapeutic drug monitoring for antidepressant drug treatment.
2012
The aim of antidepressant drug treatment is to produce remission without causing adverse effects during the acute phase of the illness and to prevent relapses or recurrences during continuation or maintenance therapy. To achieve these goals, drug choice and dosage must be optimized for each patient individually. Therapeutic drug monitoring (TDM), which is based on the assumption that clinical effects correlate better with blood levels than doses, can be helpful. When using tricyclic antidepressant drugs TDM enhances safety and efficacy. For newer antidepressant drugs, however, it is a matter of debate to which extend TDM can have beneficial effects. For many antidepressants there exist care…
Comparative analysis of direct and indirect costs of two minimally invasive techniques for the treatment of renal/ureteral calculi smaller than 2 cm
2020
[EN] Objective: To perform a comparative analysis of indirect and direct costs of two minimally invasive techniques (extracorporeal shock wave lithotripsy (ESWL) vs. ureteroscopy with holmium laser (URS/RIRS)) for the treatment of renal/ureteral calculi smaller than 2 cm. Material and methods: Prospective, comparative, non-randomized study of 84 patients treated for kidney stones smaller than 2 cm between January and December 2016. Of these, 38 (45.67%) were treated with ESWL (18 renal lithiasis and 20 ureteral lithiasis) and 46 (54.32%) with URS/RIRS (22 renal lithiasis and 24 ureteral lithiasis). A total of 19 (41.3%) patients in the URS/RIRS group and 15 (39.5%) patients in the ESWL grou…
Foreign sourcing and exporting
2020
The aim in this paper is analysing the role of sourcing intermediate inputs internationally on export decisions, distinguishing whether intermediate are sourced from firms belonging to the same business group or from independent suppliers. To analyse firm’s export decision, we use a specification that also accounts for sunk costs and the accumulated experience in export markets (i.e., foreign markets learning). We consider that importing intermediates might have direct and indirect effects (operating through productivity) on the export participation decision. The direct effects on exporting are isolated once we control for productivity and the effects of belonging to an international group.…
Trade Costs, Trade Balances, and Current Accounts: an application of Gravity to Multilateral Trade
2005
In this paper we test the well-known hypothesis of Obstfeld and Rogoff (NBER Macroeconomics Annual 7777:339–390, 2000) that trade costs are the key to explaining the so-called Feldstein–Horioka puzzle. Our approach has a number of novel features. First, we focus on the interrelationship between trade costs, the trade account and the Feldstein–Horioka puzzle. Second, we use the gravity model to estimate the effect of trade costs on bilateral trade and, third, we show how bilateral trade can be used to draw inferences about desired trade balances and desired intertemporal trade. Our econometric results provide strong support for the Obstfeld and Rogoff hypothesis and we are also able to recon…
