AbstractPalm oil mill effluent (POME) is well known as agricultural wastewater that has a high potential as a medium for microalgal growth due to its high macro- and micronutrient content. The cyanobacterium Arthrospira platensis is considered as a species with a high C-phycocyanin (C-PC) content which is important for fine chemical and pharmaceutical applications. However, cultivation of A. platensis on POME to produce economically feasible amounts of C-PC has not been well explored. For this, environmental, nutritional, and cultivation modes (batch, semi-continuous) were varied to optimize C-PC productivity when cultivated at various POME concentrations. Arthrospira platensis was found to grow well on POME. Highest biomass and C-PC concentrations were found on 30–100% POME. Central composite rotatable design (CCRD) response surface methodology demonstrated that C-PC productivity was influenced by urea addition at the optimum salinity. The highest C-PC productivity was found on 100% POME during semi-continuous cultivation, while the addition of phosphorus and urea did not significantly improve C-PC productivity. By applying semi-continuous cultivation with 50% POME at the first stage and 100% POME at the second stage, a similarly high C-PC productivity (4.08 ± 1.3 mg L−1 day−1) was achieved as compared with (artificial) Zarrouk medium during batch cultivation. We conclude that, when using a two-stage semi-continuous cultivation process, A. platensis can produce economically feasible amounts of C-PC when cultivated on 100% POME.

AbstractBackground:Little is known about changes in brain functioning after first-episode psychosis (FEP). Such knowledge is important for predicting the course of disease and adapting interventions. Functional magnetic resonance imaging has become a promising tool for exploring brain function at the time of symptom onset and at follow-up.Method:A systematic review of longitudinal fMRI studies with FEP patients according to PRISMA guidelines. Resting-state and task-activated studies were considered together.Results:Eleven studies were included. These reported on a total of 236 FEP patients were evaluated by two fMRI scans and clinical assessments. Five studies found hypoactivation at baseline in prefrontal cortex areas, two studies found hypoactivation in the amygdala and hippocampus, and three others found hypoactivation in the basal ganglia. Other hypoactivated areas were the anterior cingulate cortex, thalamus and posterior cingulate cortex. Ten out of eleven studies reported (partial) normalization by increased activation after antipsychotic treatment. A minority of studies observed hyperactivation at baseline.Conclusions:This review of longitudinal FEP samples studies reveals a pattern of predominantly hypoactivation in several brain areas at baseline that may normalize to a certain extent after treatment. The results should be interpreted with caution given the small number of studies and their methodological and clinical heterogeneity.

AbstractThis study investigated the genetic and environmental contributions to emotional overeating (EOE) and depressive symptoms, and their covariation, in a Sri-Lankan population, using genetic model-fitting analysis. In total, 3957 twins and singletons in the Colombo Twin and Singleton Study-Phase 2 rated their EOE behaviour and depressive symptoms, which were significantly associated (men: r = 0.11, 95% confidence interval (CI) 0.06–0.16, women: r = 0.12, 95% CI 0.07–0.16). Non-shared environmental factors explained the majority of variance in men (EOE e2 = 87%, 95% CI 78–95%; depressive symptoms e2 = 72%, 95% CI 61–83%) and women (EOE e2 = 76%, 95% CI 68–83%; depressive symptoms e2 = 64%, 95% CI 55–74%). Genetic factors were more important for EOE in women (h2 = 21%, 95% CI 4–32%) than men (h2 = 9%, 95% CI 0–20%). Shared-environmental factors were more important for depressive symptoms in men (c2 = 25%, 95% CI 10–36%) than women (c2 = 9%, 95% CI 0–35%). Non-shared environmental factors explained the overlap between depressive symptoms and EOE in women but not in men. Results differed from high-income populations, highlighting the need for behavioural genetic research in global populations.
Varieties of Inclusionary Populism? SYRIZA, Podemos and the Five Star Movement
Authors: Font Nuria , Graziano Paolo , Tsakatika Myrto 
Published: May 2019

AbstractOver the past years, parties often described as populist, such as SYRIZA in Greece, the Five Star Movement (FSM) in Italy and Podemos in Spain have made significant electoral breakthroughs, unsettling well-established party systems. In the literature, inclusionary populism has primarily been applied to Latin America whereas the three Southern European parties have been examined individually, but not in comparative perspective. The purpose of this article is to provide a comparative analysis, based on an original electoral manifestos content analysis, aimed at unveiling the ‘inclusionary populism’ features of the ‘new’ political parties that have emerged in Southern Europe. By focusing on the 2012–16 period, the article shows that the inclusionary category can be fruitfully applied also to European political parties; it finds different degrees of inclusionary populism (namely between SYRIZA and Podemos); and it proves that the FSM falls between the two exclusionary vs. inclusionary poles.
Operational dilemmas in safety-critical industries: The tension between organizational reputational concerns and the effective communication of risk

Published: May 2019

AbstractOrganizations involved in safety-critical operations often deal with operational tensions, especially when involved in safety-critical incidents that is likely to violate safety. In this paper, we set out to understand how the disclosures of safety-critical incidents take place in the face of reputational tension. Based on the case of the Nigerian National Petroleum Corporation (NNPC), we draw on image repair theory and information manipulation theory and adopt discourse analysis as a method of analyzing safety-critical incident press releases and reports from the NNPC. We found NNPC deploying image repair as part of incident disclosures to deflect attention, evade blame and avoid issuing apologies. This is supported by the violation of the conversational maxims. The paper provides a theoretical model for discursively assessing the practices of incident information disclosure by an organization in the face of reputational tension, and further assesses the risk communication implications of such practices.
Between ‘going private’ and ‘NHS privatisation’: patient choice, competition reforms and the relationship between the NHS and private healthcare in England
Authors: Guy Mary 
Published: May 2019

AbstractPatient choice in the context of National Health Service (NHS) reforms in England can refer to the law and policy underpinning patient movement between the NHS and private healthcare sector (in existence since the introduction of the NHS in 1948), as well as recent competition reforms of the Health and Social Care Act 2012, the National Health Service (Procurement, Patient Choice and Competition) (No 2) Regulations 2013 and the 2014 Private Healthcare Market Investigation by the Competition and Markets Authority (CMA). This paper highlights the existence of two discrete, yet related frameworks: the ‘NHS patient – private patient’ framework based on Department of Health, NHS England and latterly Clinical Commissioning Group policy, and the ‘NHS patient choice’ framework, derived from New Labour choice and competition policies and subsequently enshrined by the 2012 Act reforms. The juxtaposition of these frameworks underscores the symbiotic relationship between the NHS and private healthcare, which raises questions about the fitness for purpose of current policy. It also helps explain why the competition reforms are difficult to implement, and suggests that the knitting together of patient choice and competition may unravel following the 2012 Act reforms and CMA private healthcare market development.

Published: May 2019

AbstractAeolian sands are the main reservoir rock in some of the largest gas fields, such as the Shell-Exxon Groningen Field, operated by NAM. Although aeolian reservoirs have been studied for many years, there is still room for improvement in the predictive modeling of such reservoirs. A pilot project with this objective was initiated by SIEP B.V. in 1997, together with Heriot-Watt University in Edinburgh, UK and with Uppsala University, Sweden, to evaluate the factors influencing aeolian systems, and to formulate a forward model using ‘fuzzy logic’.The project was initiated to develop a fuzzy system for generic modeling of aeolian architectures. The key aims were to be able to predict the type, amount and distribution of major facies in generic aeolian systems and specifically to model regional-scale architecture in the sub-surface. Fuzzy rules and sets, which defined the behaviour of aeolian systems, were constructed and used to modify the pre-existing fuzzy modeling software which had been designed for shallow and deep marine systems. The modeling procedure used input data appropriate to the Rotliegend climate, and was validated by comparing the resulting models, in terms of thickness and spatial distribution of facies types, to well data from the Upper Rotliegend interval of the Lauwerszee Trough area, NE Netherlands (Figures 1 & 2).
Medieval Roots of the Myth of Jewish Male Menses
Authors: Resnick Irven M. 
Published: May 2019

Good historical fiction reveals not only the realities of a particular epoch, but also its cultural attitudes. An excellent example is Bernard Malamud'sThe Fixer, which succeeds in disclosing the nature of Russian anti-semitism by artfully weaving together enduring themes of anti-Jewish Christian mythology—the blood libel and accusations of ritual murder—to illustrate the fabric of Jewish life in early modern Russia. Perhaps almost unnoticed in his work, however, are references to the myth of Jewish male menses. Consider the following passages fromThe Fixer, in which the Jewish defendant, Yakov Bok, is confronted by this bizarre contention:“You saw the blood?” the Prosecuting Attorney said sarcastically. “Did that have some religious meaning to you as a Jew? Do you know that in the Middle Ages Jewish men were said to menstruate?” Yakov looked at him in surprise and fright. “I don't know anything about that, your honor, although I don't see how it could be.”

AbstractResults from prospective surveillance of nosocomial infections (NIs) in a small community hospital were evaluated, and a case-control study was conducted. The rate of 1.4 NIs per 100 discharges determined by prospective surveillance was found to be underestimated. Prematurity, pediatric service, surgery, length of stay, and age were independently associated with NI.
FERTILITY CONTROL DUE TO SHORT-TERM ECONOMIC STRESS IN RURAL ARAGÓN (SPAIN), 1801–1909
Authors: Marco-Gracia Francisco J. 
Published: May 2019

ABSTRACTThis paper deals with the permanent existence of deliberate fertility control arising from short-term economic stress among rural farm workers. The micro-level analysis uses the family reconstitution method for ten rural Spanish localities. The husband's socio-economic level is regarded as an indicator of the family's socio-economic status. According to the available data, human agency between 1801 and 1909 resulted in a negative fertility response among all farm groups, with this negative response being especially strong among the landless and semi-landless. The existence of a rapid fertility control response suggests that such control was a voluntary decision. Since the end of the 19thcentury, the number of economic shocks due to high prices has reduced.
The development of new embryo-based biotechnology procedures to aid reproductive function in cattle
Authors: Boland M.P. , Lonergan P. , Sreenan J.M. 
Published: May 2019

AbstractFertility in dairy cows has decreased during the past 50 years and current management procedures have done little to rectify this situation. Following intense selection for increased milk production, there are significantly more problems in establishing pregnancy at the appropriate time. In recent years, major strides have been made in the development of new embryo-based biotechnologies, including in vitro embryo production, ovum pick-up, cryopreservation of gametes and embryos, cloning and sexing of gametes. The objectives of this paper are to review current progress relating to embryo-based technologies in cattle.
Characterization of homogeneous scalar variational problems solvable for all boundary data
Authors: Sychev M. A. 
Published: May 2019

It is known that the condition ‘either ∂L (F) ≠ Ø or there exist υ1,…,υq ∈ Rnsuch thatF ∈ int co {υ1,…,υq} characterizes solvability of the problem

with f(·) = 〈F,·〉.We extend this result to the case of lower semicontinuous integrands L : Rn → R.We also show that validity of this condition for all F ∈ Rn is both a necessary and sufficient requirement for solvability of all minimization problems with sufficiently regular Ω and f. Moreover, the assumptions on Ω and f can be completely dropped if L has sufficiently fast growth at infinity.

Published: May 2019

ABSTRACT:Background:Endovascular therapy is becoming an increasingly popular treatment for cerebral aneurysms. Total angiographic occlusion of small-necked aneurysms (<4 mm) can be obtained in a high percentage of cases. The endovascular treatment of wide-necked or fusiform aneurysms remains a challenge with complete angiographic occlusion reported in <15% of cases.Case Report:We describe the combined use of a flexible coronary stent and platinum coils to treat a wide-necked aneurysm of the distal left vertebral artery, in a patient with Grade IV subarachnoid hemorrhage.Results:The procedure was technically successful as the parent artery was protected by the stent while coils were deposited in the aneurysm lumen. Although angiographic aneurysm occlusion was incomplete, the dome was packed with coils. No further hemorrhage has occurred.Conclusion:Combined endovascular stent and coil therapy is a promising technique for the treatment of wide-necked cerebral aneurysms.
SHORT COMMUNICATION Increased sensitivity to green light during transition from conditional dormancy to nondormancy in seeds of three species ofSolidago(Asteraceae)

Published: May 2019

AbstractGermination responses of nonstratified (conditionally dormant) and of cold-stratified (nondormant) seeds of threeSolidagospecies were tested in darkness at 30/15°C following various lengths of exposure [0 (control), 5 and 30 min, 1, 6 and 14 h] to green (mostly 500–600 nm) or white (400–700 nm) light. Prior to exposures, nonstratified seeds were imbibed in darkness at laboratory conditions for 24 h, and cold-stratified seeds were kept in darkness at 5°C on a moist substrate for 8 wk. Nonstratified seeds ofS. altissima,S. nemoralisandS. shortiigerminated to 0–46%, 0–25% and 36–99%, respectively, in darkness following 5 min to 14 h of green or white light, whereas cold-stratified seeds germinated to 53–98%, 31–85% and 82–100%, respectively. Thus, sensitivity of seeds to both green and white light increased as they passed from conditional dormancy to nondormancy. Moreover, sensitivity to green and white light was similar to the hierarchy of seed size. Green safe lights must be used with caution in interpreting the results of studies on light/dark responses of seeds.
Effect of tryptophan on the utilization of intra-duodenally infused labelled glucose in piglets given food at 1·35 times maintenance energy
Authors: Ponter A. A. , Matte J. J. , Sève B. 
Published: May 2019

AbstractTwo experiments were conducted. The first, studied the chronic effect of tryptophan (trp) on glucose disposal and the second, the acute effect of trp on glucose disposal. In experiment 1, 12 piglets were allocated either to a trp deficient diet (T0) or a trp adequate diet (T1). After 14 days a 240-min intraduodenal infusion of glucose (130 µmol/kg per min) associated with D-(U-14C) glucose (1·18 kBq/kg per min) and an intrajugular infusion of D-(6-3H) glucose (1·85 kBq/kg per min) were started. In experiment 2, 18 piglets were given a trp adequate diet (T1) for 14 days. The piglets were then divided into two groups and received an intraduodenal infusion of either glucose (130 µmol/kg per min) or glucose plus trp (0·53 µmol/kg per min) for 240 min. At the same time an intrajugular infusion of D-(U-14C)glucose (1·48 kBq/kg per min) and D-(6-3H)glucose (2·59 kBq/kg per min) was given to all piglets. Blood samples were taken at regular intervals during the infusions for the measurement of plasma concentrations of insulin, glucose, lactate and blood specific activities of14C-glucose,14C-lactate,3H-glucose and3H-lactate. At the end of the infusion, samples were taken for the measurement of the accumulation of14C and3H in glycogen. In experiment 1, plasma insulin concentrations were higher in the T0 compared with the T1 group (at 30 min respectively, 837·7 (s.e.56·6) v. 404·9 (s.e.56·6) pmol/l,P< 0·001). Glucose concentrations were also higher in T0 compared with T1 (at 30 min respectively, 10·9 (s.e. 0·54) v. 9·3 (s.e. 0·54) mmol/l,P< 0·05). Glucose flux was unaffected by trp in both experiments. The accumulation of labelled glucose into liver and carcass glycogen was not affected by trp. The route of administration of glucose label had a significant effect on the percentage of label accumulated in liver glycogen. When both14C and3H were infused into the jugular vein there was no difference in the accumulation of the two tracers in liver glycogen (22·7 v. 21·8% of that infused,P> 0·05, respectively). However, when 14C was infused into the duodenum and3H into the jugular vein, accumulation into liver glycogen was higher for14C compared with3H (19·9 v. 15·6%,P< 0·001, respectively). In conclusion, trp does not appear to influence glucose disposal measured at the end of a 240 min intraduodenal glucose infusion. Contrary to results published from experiments with rats the indirect pathway for glycogen synthesis (glucose→lactate→glycogen) does not appear to occur in underfed piglets.
Quantification of changes in body weight and body condition scores during lactation by modelling individual energy balance and total net energy intake
Authors: Schwager-Suter R. , Stricker C. , Erdin D. , Künzi N. 
Published: May 2019

AbstractIndividual energy balances (EB) and total net energy intake (NEI) were modelled to quantify the energy content of the explanatory variables body-weight change corrected for gut fill (BWC) and body condition-score change (BCSC). A total of 6147 records from 213 lactating dairy cows, 71 Holstein-Friesians, 71 Jerseys and 71 HolsteinJersey F1-crosses was analysed (1st, 2nd and >2nd lactation). Data were collected during 210 days of lactation, from calving to week 30. Individual EB were calculated as total energy for lactation (MJ NEL) minus estimated energy necessary for maintenance and production. Body-weight changes were calculated as differences between weekly means of body weight corrected for gut fill (BWCw) as well as from polynomial regression (BWCp). BCSC were differences between assessed body condition scores. The study included analyses of 1- and of 4-week periods for BWCw and BWCp, of differences between measuring periods for BCSC as well as separate analyses of data from cows in either negative or positive energy balance.Analysis of repeated measurements were performed applying mixed model theory. Models for EB contained type of dairy cow, lactation and type of roughage as fixed effects, week of lactation and either BWCw, BWCp or BCSC. Models for NEI contained type of dairy cow, lactation and quality of roughage as fixed effects, week of lactation as well as energy corrected milk, metabolic body weight and either BWCw, BWCp or BCSC as covariates.Most plausible energy contents per unit body tissue change were estimated for BWCp from weekly data with either EB (with energy partitioned into milk production and maintenance fixed) or NEI (no restrictions concerning partitioning) as the response variable. The estimated energy contents for BWCp were 15·40 and 10·47 MJ NEL, respectively.
The effects of dietary urea on embryo development in superovulated donor ewes and on early embryo survival and development in recipient ewes

Published: May 2019

AbstractThe aim was to examine the effect of dietary urea on yield and quality of embryos in superovulated donor ewes, and on embryo survival in recipient ewes. Ewes (25 donors and 34 recipients) were offered 1·25 kg of grass meal containing 50 g urea per ewe per day on a group basis; the remaining ewes (30 donors and 32 recipients) received 1·25 kg untreated grass meal per day. After 5 days, ewes were synchronized using a progestagen pessary for 14 days and stimulated with pregnant mare serum gonadotropin. Donors were naturally mated; recipients were detected in oestrus using vasectomized rams. On day 4 following the onset of oestrus, embryos were recovered from donors, graded morphologically and cell number counted. Two embryos of acceptable morphological grade (≥ eight cells on day 4) were then surgically transferred to recipient ewes. Recipients were slaughtered between days 34 and 36 post oestrus. The mean number of embryos recovered per ewe [3·68 (s.e. 0·41) v. 3·83 (s.e. 0·45)] was not different between untreated and urea-treated ewes, respectively. However, urea treatment of donor ewes reduced the mean cell number per embryo (10·27 (s.e. 0·27) v. 8·17 (s.e. 0·29) for untreated and urea-treated donor ewes, respectively,P< 0·001). Similarly, the percentage of embryos recovered that had ≥ 10 cells and their mean cell number was reduced following urea treatment of donor ewes (82/113 (73%) v. 39/93 (42%),P< 0·01 and 11·61 (s.e. 0·20) v. 10·41 (s.e. 0·29),P< 0·001) for untreated and urea-treated ewes, respectively. The diet offered to recipient ewes had no effect on the number of ewes confirmed pregnant (24/32 (75%) v. 28/34 (82%)) or on embryo survival following transfer (45/64 (70%) v. 51/68 (75%) for untreated and urea-treated ewes, respectively,P> 0·05). Excess nonprotein nitrogen in the form of dietary urea reduced embryo quality. However, embryo survival in recipient ewes was not affected when good quality embryos were transferred. This suggests that the deleterious effects of excess dietary urea are due to alterations to the oocyte and (or) the oviductal environment rather than changes in the uterine environment.
