General procedure to initialize the cyclic soil water balance by the Thornthwaite and Mather method

The original Thornthwaite and Mather method, proposed in 1955 to calculate a climatic monthly cyclic soil water balance, is frequently used as an iterative procedure due to its low input requirements and coherent estimates of water balance components. Using long term data sets to establish a characteristic water balance of a location, the initial soil water storage is generally assumed to be at field capacity at the end of the last month of the wet season, unless the climate is (semi-) arid when the soil water storage is lower than the soil water holding capacity. To close the water balance, several iterations might be necessary, which can be troublesome in many situations. For (semi-) arid climates with one dry season, Mendon a derived in 1958 an equation to quantify the soil water storage monthly at the end of the last month of the wet season, which avoids iteration procedures and closes the balance in one calculation. The cyclic daily water balance application is needed to obtain more accurate water balance output estimates. In this note, an equation to express the water storage for the case of the occurrence of more than one dry season per year is presented as a generalization of Mendon a's equation, also avoiding iteration procedures

The mechanical properties of thin alumina film deposited by metal-organic chemical vapour deposition

Amorphous alumina films were deposited by metal-organic chemical vapour deposition (MOCVD) on stainless steel, type AISI 304. The MOCVD experiments were performed in nitrogen at low and atmospheric pressures. The effects of deposition temperature, growth rate and film thickness on the mechanical properties have been studied.\ud \ud The experiments were performed with the dynamic ultra-micro-hardness tester, DUH-200, and the scanning scratch tester, SST-101, both developed by Shimadzu. The DUH-200 is associated with crack formation during indentation. This technique involves a qualitative method to study the crack behaviour of the thin alumina films as well as a method to estimate the fracture toughness of the film and the film/substrate interface. The experiments performed with the SST-101 are based on the estimation of the film adhesion to the substrate by determining a critical load; the load where the film starts to spall or to delaminate.\ud \ud The best mechanical properties were obtained using low deposition rates and high deposition temperatures. Therefore, low-pressure MOCVD is recommended in addition to the deposition of alumina films at high temperatures

Renal function at two years in liver transplant patients receiving everolimus: results of a randomized, multicenter study

Abstract In a 24-month prospective, randomized, multicenter, open-label study, de novo liver transplant patients were randomized at 30 days to everolimus (EVR) + Reduced tacrolimus (TAC; n = 245), TAC Control (n = 243) or TAC Elimination (n = 231). Randomization to TAC Elimination was stopped prematurely due to a significantly higher rate of treated biopsy-proven acute rejection (tBPAR). The incidence of the primary efficacy endpoint, composite efficacy failure rate of tBPAR, graft loss or death postrandomization was similar with EVR + Reduced TAC (10.3%) or TAC Control (12.5%) at month 24 (difference -2.2%, 97.5% confidence interval [CI] -8.8%, 4.4%). BPAR was less frequent in the EVR + Reduced TAC group (6.1% vs. 13.3% in TAC Control, p = 0.010). Adjusted change in estimated glomerular filtration rate (eGFR) from randomization to month 24 was superior with EVR + Reduced TAC versus TAC Control: difference 6.7 mL/min/1.73 m(2) (97.5% CI 1.9, 11.4 mL/min/1.73 m(2), p = 0.002). Among patients who remained on treatment, mean (SD) eGFR at month 24 was 77.6 (26.5) mL/min/1.73 m(2) in the EVR + Reduced TAC group and 66.1 (19.3) mL/min/1.73 m(2) in the TAC Control group (p < 0.001). Study medication was discontinued due to adverse events in 28.6% of EVR + Reduced TAC and 18.2% of TAC Control patients. Early introduction of everolimus with reduced-exposure tacrolimus at 1 month after liver transplantation provided a significant and clinically relevant benefit for renal function at 2 years posttransplant

#AnneFaber Een onderzoek naar de wisselwerking tussen traditionele en sociale media rond de vermissing van Anne Faber

De vermissing van Anne Faber, een 25-jarige studente die uiteindelijk bleek te zijn verkracht en vermoord door een zedendelinquent die eerder geen tbs kreeg opgelegd, domineerde begin oktober 2017 zowel de Nederlandse traditionele als sociale media en maakte veel los in Nederland. Na veel emotie sloeg de toon om in woede: had het rechtssysteem de dood van Anne Faber kunnen voorkomen? De media-aandacht voor beide perspectieven, die zorgden voor maatschappelijke onrust en druk op de overheid, verspreidde zich gelijktijdig over zowel traditionele als sociale media. Sociale media zijn niet meer weg te denken uit het medialandschap en daarom is aan de hand van de media-aandacht rond de vermissing van Anne Faber tot een vernieuwing gekomen van de criteria van een mediahype zoals eerder opgesteld door Vasterman (2005). Een kwantitatieve inhoudsanalyse van berichtgeving in Nederlandse online en offline media laat zien dat er op hetzelfde moment een mediabrede mediahype ontstond, waarbij er sprake was van een constante wisselwerking tussen alle mediagroepen. In het huidige medialandschap kan daarom niet meer worden gesproken over verschillende mediahypes die aanleiding zijn voor extreme aandacht in een andere mediagroep, maar ontstaat één mediahype die betrekking heeft op het gehele medialandschap waarbij alle mediagroepen hun eigen karakteristieken behouden. Media hebben de dood van Anne Faber gezamenlijk tot een signal crime geconstrueerd, waarbij door emoties op te wekken een roep vanuit de samenleving is ontstaan dat het rechtssysteem moet worden aangepast. Dit proces heeft plaatsgevonden door een verandering van perspectief van het human interestframe naar een schuldvraag in brede zin, waarbij interne ‘triggers’ leidden tot een mediabrede wisseling in aandacht en verschuiving van perspectief. Bij een emotionele mediahype als die van Anne Faber kan daarom niet worden gesproken van een vaste duur en verloop van nieuwsgolven, maar is de periodisering afhankelijk van veranderingen in perspectief en daarmee verandering in framegebruik. Een explosie van interactie waarin burgers dominant waren zorgde ervoor dat media altijd ergens over konden berichten. Het verloop van deze mediahype bevestigt dat een aanpassing van het concept mediahype in het huidige medialandschap gerechtvaardigd is

Epidemic malaria and warmer temperatures in recent decades in an East African highland

Climate change impacts on malaria are typically assessed with scenarios for the long-term future. Here we focus instead on the recent past (1970–2003) to address whether warmer temperatures have already increased the incidence of malaria in a highland region of East Africa. Our analyses rely on a new coupled mosquito–human model of malaria, which we use to compare projected disease levels with and without the observed temperature trend. Predicted malaria cases exhibit a highly nonlinear response to warming, with a significant increase from the 1970s to the 1990s, although typical epidemic sizes are below those observed. These findings suggest that climate change has already played an important role in the exacerbation of malaria in this region. As the observed changes in malaria are even larger than those predicted by our model, other factors previously suggested to explain all of the increase in malaria may be enhancing the impact of climate change

Explaining the willingness of public professionals to implement new policies: A policy alienation framework

Nowadays, many public policies focus on economic values, such as efficiency and client choice. Public professionals often show resistance to implementing such policies. We analyse this problem using an interdisciplinary approach. From public administration, we draw on the policy alienation concept, which consists of five dimensions: strategic powerlessness, tactical powerlessness, operational powerlessness, societal meaninglessness and client meaninglessness. These are considered as factors that influence the willingness of professionals to implement policies (change willingness - a concept drawn from the change management literature). We test this model in a survey among 478 Dutch healthcare professionals implementing a new reimbursement policy. The first finding was that perceived autonomy (operational powerlessness) significantly influenced change willingness, whereas strategic and tactical powerlessness were not found to be significant. Second, both the meaninglessness dimensions proved highly significant. We conclude that clarifying the value of a policy is important in getting professionals to willingly implement a policy, whereas their participation on the strategic or tactical levels seems less of a motivational factor. These insights help in understanding why public professionals embrace or resist the implementation of particular policies. Points for practitioners Policymakers develop public policies which, nowadays, tend to focus strongly on economic values, such as increasing efficiency or offering citizens the opportunity to choose among suppliers of public services. Public professionals, who have to implement these policies, are often reluctant to do so. This study shows that the causes of this resistance are unlikely to be found in the lack of influence these professionals have in the shaping of the policy at the national or organizational level. Rather, professionals might resist implementing policies because they do not see them as meaningful for society, or for their own clients. Therefore, policymakers should focus on this perceived meaninglessness and adopt ways to counter this, for example by intensively communicating the value associated with a policy
