Authors: Wagner Jamie L. , Kenney Rachel M. , Vazquez Jose A. , Ghanem Tamer A. , Davis Susan L.
Published: July 2016

Background

The purpose of this study was to determine the incidence of and risk factors for surgical site infections in microvascular reconstruction for patients with head and neck cancer.

Methods

One hundred seventeen patients with head and neck cancer undergoing microvascular reconstruction received postoperative surgical infection prophylaxis and were followed for 30 days. Surgical infection prophylaxis was categorized by empiric spectrum of activity. Risk factors for surgical site infection development and cumulative incidence of surgical site infections were characterized.

Results

Thirty‐seven patients developed surgical site infection (cumulative surgical site infection incidence of 31.6%). Risk factors identified in logistic regression include alcohol use (odds ratio [OR] = 2.704; 95% confidence interval [CI] = 1.029–7.106), increased surgical duration (OR = 1.403; 95% CI = 1.185–1.661), American Society of Anesthesiologists (ASA) class IV (OR = 3.075; 95% CI = 1.000–9.459), and lack of postoperative gram‐negative coverage (OR = 15.139; 95% CI = 3.083–74.347).

Conclusion

Alcohol use, longer surgical duration, and lack of gram‐negative postoperative prophylactic coverage are modifiable risk factors for surgical site infection development. © 2016 Wiley Periodicals, Inc. Head Neck 38: First–1454, 2016
Understanding the time‐varying importance of different uncertainty sources in hydrological modelling using global sensitivity analysis
Authors: Pianosi Francesca , Wagener Thorsten
Published: July 2016

Simulations from hydrological models are affected by potentially large uncertainties stemming from various sources, including model parameters and observational uncertainty in the input/output data. Understanding the relative importance of such sources of uncertainty is essential to support model calibration, validation and diagnostic evaluation and to prioritize efforts for uncertainty reduction. It can also support the identification of ‘disinformative data’ whose values are the consequence of measurement errors or inadequate observations. Sensitivity analysis (SA) provides the theoretical framework and the numerical tools to quantify the relative contribution of different sources of uncertainty to the variability of the model outputs. In traditional applications of global SA (GSA), model outputs are aggregations of the full set of a simulated variable. For example, many GSA applications use a performance metric (e.g. the root mean squared error) as model output that aggregates the distances of a simulated time series to available observations. This aggregation of propagated uncertainties prior to GSA may lead to a significant loss of information and may cover up local behaviour that could be of great interest. Time‐varying sensitivity analysis (TVSA), where the aggregation and SA are repeated at different time steps, is a viable option to reduce this loss of information. In this work, we use TVSA to address two questions: (1) Can we distinguish between the relative importance of parameter uncertainty versus data uncertainty in time? (2) Do these influences change in catchments with different characteristics? To our knowledge, the results present one of the first quantitative investigations on the relative importance of parameter and data uncertainty across time. We find that the approach is capable of separating influential periods across data and parameter uncertainties, while also highlighting significant differences between the catchments analysed.

Prediction of tumor recurrence after curative resection is critical for determining the prognosis of patients with gastric cancer (GC). The initiation and progression of GC are associated with inappropriate immune responses caused by chronic inflammation of the gastric mucosa. To identify immunoregulatory molecules involved in GC progression, GC cell lines and 200 pairs of tumor and normal tissues from patients with GC were analyzed for gene expression, amplification and methylation as well as function of a differentially expressed gene. The transcriptome analysis revealed that marginal zone B and B1 cell specific protein (MZB1) was expressed at significantly decreased levels in primary GC tissues when compared with the corresponding normal gastric mucosa. PCR array analysis exploring genes expressed cooperatively with MZB1 revealed that differential expression of MZB1 mRNA in GC cell lines correlated positively with the levels of the mRNAs encoding estrogen receptor 1 and desumoylating isopeptidase 1. Hypermethylation of the MZB1 promoter was frequent in cell lines with decreased levels of MZB1 mRNA. siRNA‐mediated knockdown of MZB1 significantly increased proliferation, invasion and migration of GC cell lines. Low MZB1 expression was an independent prognostic factor for recurrence after curative gastrectomy and was associated significantly with increased hematogenous recurrence. MZB1 acts as a suppressor of GC. Low MZB1 expression in the primary GC tissue is predictive of recurrence after curative resection.

Published: July 2016

Deoxynivalenol (DON, also known as vomitoxin) is a common mycotoxin found worldwide, especially in contaminated food. DON is toxic to a variety of cells and tissues in humans. Three kinds of conjugated products (DON‐3‐glucuronide, DON‐15‐glucuronide and DON‐7‐glucuronide) can be found as major metabolites in human urine. Females and males show different patterns of exposure levels, and human exposure to DON also shows some geographical differences because of different DON levels in cereal‐based foods, food intake habits and UDP‐glucuronosyltransferase expression. Specifically, the C12, 13‐deepoxy metabolite was found predominantly in French adults but was rarely detected in UK adults. However, a cohort of Spanish individuals demonstrated even lower DON levels than the levels in the UK populations, whereas a very high DON exposure level was detected in South Africa and Linxian, China. Recent publications have further indicated that DON could be detected in the urine of pregnant women from different countries, which suggests that there is a potential risk to both mothers and foetuses. Additionally, phytochemicals have been shown to be less toxic to cells and laboratory animals in research studies and may also be used as food additives for reducing the toxic effects of DON. In this review, we provide global information on DON metabolism, human exposure and gender differences in humans. Also, control strategies for this mycotoxin are discussed.

Ureteral double‐J stents performances toward encrustation after long‐term indwelling in a dynamic in vitro model
Authors: Cauda Valentina , Chiodoni Angelica , Laurenti Marco , Canavese Giancarlo , Tommasi Tonia
Published: July 2016

Three different single‐lumen double‐J ureteral stents of different materials were studied and compared after the insertion into a dynamic in vitro model with sterile artificial urine up to 6 months. The aim was to evaluate, at selected time steps of 1, 3, and 6 months, the material performances of the stents in preventing the formation of inorganic encrustations. Morphological, compositional, and qualitative analyses were carried out both before stent insertion and after stent permanence for the different time steps, showing an increasing level of encrustation which remains particularly low in the case of two polyurethane stents. Mechanical tests show that both the polyurethane stents and the chitosan one do not decrease the tensile strength after 6 months of indwelling. Evaluation of the wetting behavior of the stent outer surfaces indicates a hydrophilic behavior in most of the cases, which is generally preserved after immersion in artificial urine for the different time steps. © 2016 Wiley Periodicals, Inc.

Hepatitis B Virus (HBV) causes liver cirrhosis and hepatocellular carcinoma. Standard therapy includes treatment with interferon (IFN); however, its efficacy is limited. HBV has been reported to impair IFN signaling; however, the mechanism is unclear. Here, the relationship between HBV X protein (HBx) and IFN signaling was investigated by establishing HepG2 cells, stably expressing HBx (HepG2/HBx) via retrovirus‐mediated gene transfer. Subsequently, IFN negative‐regulator expression and its mechanism were studied. HepG2/HBx cells showed reduced expression of IFN‐stimulated genes and expressed higher levels of suppressor of cytokine signaling 3 (SOCS3) and protein phosphatase 2A (PP2A) suppressor compared with control cells. Knockdown of SOCS3 and PP2A restored IFN sensitivity. Moreover, HepG2/HBx cells showed higher phosphorylation levels of signal transducers and activators of transcription 3 and endoplasmic reticulum stress, which are inducers of SOCS3 and PP2A, respectively. Additionally, HBx‐knockdown restored IFN sensitivity in HepG2.2.15.7 cells. It was also confirmed that SOCS3 and PP2A expression levels were up‐regulated in the liver of patients with HBV infection. The results of this study demonstrated that HBx impairs IFN signaling via increased expression of SOCS3 and PP2A, a novel mechanistic insight, providing a potential therapeutic target to enhance the efficiency of IFN therapy.

Temperature and precipitation regional climate series over the central Pyrenees during 1910–2013
Authors: Pérez‐Zanón Núria , Sigró Javier , Ashcroft Linden
Published: July 2016

Quality controlled homogenized regional anomaly series of temperature and precipitation are obtained for the central Pyrenees for the period 1910–2013. A 0.1 °C decade−1 positive trend is found for minimum and maximum annual temperature exceeding the significance level of 0.05 for the whole studied period. A significant warming is found in all seasons except boreal spring in minimum temperature and winter in maximum temperature. The annual regional precipitation anomaly series shows a high inter‐annual variability and a slightly negative non‐significant trend of −0.6% decade−1. Non‐significant negative trends of precipitation are found in all seasons for the whole period examined. Considering the recent period 1970–2013, values of temperature trends are generally higher than those obtained for the whole period. For this latest period, all maximum temperature trends are significant while only the minimum temperature trend in winter is non‐significant. Spring is the season that presents the greatest warming, with 0.9 °C decade−1 for maximum temperature and 0.4 °C decade−1 for minimum temperature. Evaluating the same period for precipitation anomalies, trends in the annual, winter and summer series remain negative, while spring and autumn trends are positive although non‐significant. This series represents the longest homogenized climate data set available for the central Pyrenees region, including the newly recovered period 1910–1949, offering new possibilities for climate analysis and paleoclimate proxy calibration.
Octadecylsilane/Nylon‐6 composite as a thin‐film microextraction sorbent for the determination of bisphenol A in water samples
Authors: Saraji Mohammad , Keikavousi Behbahan Arnavaz
Published: July 2016

We report on the fabrication of a thin‐film composite for the extraction of bisphenol A from aqueous solutions. Nylon‐6, C18 particles, and polyethylene glycol were used to prepare the thin film sorbent. Bisphenol A was used as a model compound to evaluate the extraction efficiency of the sorbent. High‐performance liquid chromatography with UV detection was used for the analysis. The extraction yield of the sorbent was compared with other thin films fabricated using different sorbents including nanoclay, LiChrolut EN, and multiwalled carbon nanotubes. Experimental parameters affecting the extraction performance (extraction time, desorption condition, sample stirring, and ionic strength of the sample solution) were investigated. The detection limit and the dynamic range of the method were 0.05 and 0.15–50 μg/L, respectively. The relative standard deviation of the method at two concentration levels (0.5 and 20 μg/L) was less than 7.2%. Finally, a polycarbonate baby bottle, river water, and wastewater samples were analyzed by the method.
On a free boundary problem for a class of anisotropic equations
Authors: Barbu Luminita , Enache Cristian
Published: July 2016

This paper deals with a certain condenser capacity in an anisotropic environment. More precisely, we are going to investigate a free boundary problem for a class of anisotropic equations on a ring domain
N≥2. Our aim is to show that if the problem admits a solution in a suitable weak sense, then the underlying domain Ω is a Wulff‐shaped ring. The proof makes use of a maximum principle for an appropriate P‐function, in the sense of L. E. Payne, a Rellich type identity and some geometric arguments involving the anisotropic mean curvature of the free boundary. Copyright © 2016 John Wiley & Sons, Ltd.
Nephrotoxicity Associated with Concomitant Use of Ledipasvir‐Sofosbuvir and Tenofovir in a Patient with Hepatitis C Virus and Human Immunodeficiency Virus Coinfection

Published: July 2016

Direct‐acting antivirals (DAAs) have revolutionized the treatment of hepatitis C virus (HCV) infection, with superior efficacy and safety compared to interferon‐based therapies. Despite these improvements, drug interactions with DAAs exist and may be clinically relevant in human immunodeficiency virus (HIV)‐coinfected patients. We present a case of nephrotoxicity associated with concomitant use of tenofovir disoproxil fumarate (TDF) and ledipasvir‐sofosbuvir (LDV‐SOF). A 56‐year‐old woman with HIV infection who had been taking efavirenz/tenofovir/emtricitabine (EFV/TDF/FTC) for 6 years developed acute kidney injury 8 weeks after initiating LDV‐SOF for the treatment of HCV infection. Her serum creatinine concentration peaked at 10 mg/dL, compared with her baseline concentration of 0.9–1 mg/dL. Kidney biopsy revealed acute tubular necrosis and acute interstitial nephritis. Both LDV‐SOF and TDF were discontinued, and the patient's serum creatinine concentration decreased to 1.3 mg/dL over the following 6 weeks. We postulate that this adverse drug reaction may have been secondary to the known interaction between ledipasvir and TDF, which results in increased TDF exposure. Despite knowledge of this interaction, LDV‐SOF is commonly prescribed in patients with HIV‐HCV coinfection, as patients who received LDV‐SOF– and TDF‐containing regimens in trials have not demonstrated adverse clinical consequences related to this interaction. This case highlights the rare but potentially serious nephrotoxicity that can result from TDF toxicity and serves as a reminder to clinicians to implement close renal function monitoring in patients receiving both LDV‐SOF and TDF. Clinicians prescribing LDV‐SOF to HCV‐HIV–coinfected patients receiving TDF should be cautious about use with concomitant nephrotoxic medications and monitor markers of tubular dysfunction, including urinary phosphorus excretion, and renal injury at baseline and week 4 of therapy. Tenofovir alafenamide and alternative DAAs may also have a role in the management of patients at high risk for renal adverse effects from TDF.

The 17th International Conference on II–VI Compounds and Related Materials was held at the Campus des Cordeliers, in the historical center of Paris, France, from September 13th to 18th.

II–VI 2015 has followed the path of a suc‐cessful series of biennial conferences which started in Durham (UK) in 1983. Recent conferences were or‐ganized in Niagara Falls (USA, 2003), Warsaw (Po‐land, 2005), Jeju (Korea, 2007), Saint Petersburg (Russia, 2009), Mayan (Mexico, 2011), and Na‐gahama (Japan, 2013).

The II–VI conference aims at providing an international forum for scientists, students and indus‐try representatives, facilitating the exchange of new ideas and establishing fructuous scientific contacts. The ambition is to report the newest developments in basic and applied research on II–VI and re‐lated compounds such as oxides and chalcopyrite semiconductors. The topics cover also novel synthe‐sis techniques, new physical properties and innova‐tive device development. Let us note that for this last edition, the scope has been extended to Related Mate‐rials like photovoltaic materials and novel 2D sys‐tems (dichalcogenides and topological insulators).

Gathering 240 participants, II–VI Paris 2015 has fulfilled its mission, with a scientific pro‐gram presenting three plenary review lectures, 15 in‐vited talks, 64 contributed talks and about 200 con‐tributed poster presentations. A special session has been devoted to the memory of Prof. Fritz Henneber‐ger from Humboldt University, Berlin.

Following the conference, this issue of physica status solidi offers a variety of basic and applied studies on optical, electrical and mag‐netic properties of II–VI compounds, related materials and devices. Achievements in practical ap‐plications of II–VI compounds will be found in infrared, visible and UV range detectors, optoelec‐tronic devices, photovoltaics. The proceedings edition also emphasizes new trends and pioneering directions, towards original related materials and devices. A total of 78 articles are published in pss  (b) (11), pss RRL (1) and pss  (c) (66). We wish that all participants would appreciate to redis‐cover and thoroughly read some of the nice results presented in Paris.

We thank all contributors and reviewers who made the edition of II–VI Paris Proceedings a great success and hope the conference as well as the unique atmosphere of Paris will remain in your heart and memory!
Synthesis and Spectroscopic Properties of PdII and PtII Complexes with Monosulfide and Monoselenide Bis(phosphanyl)amine Ligands
Authors: Al‐Masri Harbi Tomah , Moussa Ziad
Published: July 2016

Oxidation of N,N‐bis(diphenylphosphanyl)naphthalen‐1‐amine (1) with elemental sulfur or gray selenium (1:1 molar ratio) gave the corresponding monosulfide and monoselenide bis(phosphanyl)amine ligands C10H7‐1‐N(P(E)Ph2)(PPh2) [E = S (2), Se (3)], respectively. Reactions of 2 and 3 with MCl2(cod) (M = Pd, Pt) afforded [MCl2{2‐κ2P,S}] [M = Pd(4), Pt(5)] and [MCl2{3‐κ2P,Se}] [M = Pd(6), Pt(7)], respectively. In contrast, reactions of the same ligands with NiCl2(PPh3)2 resulted in deselenization and desulfurization, producing complex 8 with the formula [NiCl2{1‐κ2P,P}]. Ligands 2 and 3, as well as their complexes 4–7 and 8 were identified and characterized by multinuclear NMR (1H, 13C, 31P, and 77Se NMR) spectroscopy, elemental analysis, and IR spectroscopy. Additionally, the molecular structure of 8 was obtained.

Published: July 2016

Successful pregnancy in African elephants is influenced by biological and environmental factors. For managed elephants many of these factors are set directly or indirectly by their human care takers, including nutrition and husbandry. While African elephants often struggle to conceive and produce healthy offspring under human care, Disney's Animal Kingdom (DAK) has effectively managed six gestations to fruition in three cows. Despite differences between mothers in terms of BW and growth curves during gravidity, each pregnancy successfully resulted in the birth of a healthy calf. Body weight (BW) gain during pregnancy ranged from 245 to 558 kg. Obesity in elephants is associated with increased occurrence of dystocia and mortality of the fetus and mother, hence understanding normal weight gains is an integral concept. Diet (dry matter basis) included high levels of fiber throughout pregnancies (60–70% neutral detergent fiber), vitamin E supplementation (116–214 mg/kg diet of alpha‐tocopherol), as well as low levels of starch (2.5–5.1%) and crude fat (1.9–2.4%). Caretaker directed exercise during pregnancy at DAK served to prevent ventral edema, and increase muscle tone to prepare cows for parturition. Demonstrating techniques for effective care of pregnant females, as well as normal growth curves and fluctuations under ex situ conditions are necessary for future positive outcomes. Ensuring reproductive success through proper husbandry and nutrition are a key to long‐term conservation of elephants. Zoo Biol. 35:574–578, 2016. © 2016 Wiley Periodicals, Inc.

Authors: Mba Ogan I. , Dumont Marie‐Josée , Ngadi Michael
Published: July 2016

The oxidation of vegetable oils is generally treated as an apparent first order kinetic reaction. This study investigated the deterioration of crude palm oil (CPO), refined canola oil (RCO) and their blend (CPO:RCO 1:1 w/w) during 20 h of successive deep‐fat frying at 170, 180 and 190 °C. Kinetics of changes in oil quality indices, namely, free fatty acid (FFA), peroxide value (PV), anisidine value (p‐AV), total polar compounds (TPC) and color index (CI) were monitored. The results showed that FFA and PV accumulation followed the kinetic first order model, while p‐AV, TPC and CI followed the kinetic zero order model. The concentration and deterioration rate constants k, increased with increasing temperatures. This effect of temperature was modeled by the Arrhenius equation. The results showed that PV had the least activation energies Ea (kJ/mol) values of 5.4 ± 1 (RCO), 6.6 ± 0.7 (CPO) and 11.4 ± 1 (blend). The highest Ea requirement was exhibited by FFA with a range of 31.7 ± 3–76.5 ± 7 kJ/mol for the three oils. The overall Ea values showed that the stability of the blend was superior and not just intermediate of CPO and RCO. The correlation of the other oil quality indices with TPC indicated a positive linear correlation. The p‐AV displayed the strongest correlation, with mean correlation coefficient rs of 0.998 ± 0.00, 0.994 ± 0.00 and 0.999 ± 0.00 for CPO, RCO and blend, respectively.

Introduction

The Mediterranean diet (MeDi) is associated with reduced risk of cognitive impairment, but it is unclear whether it is associated with better brain imaging biomarkers.

Methods

Among 672 cognitively normal participants (mean age, 79.8 years, 52.5% men), we investigated associations of MeDi score and MeDi components with magnetic resonance imaging measures of cortical thickness for the four lobes separately and averaged (average lobar).

Results

Higher MeDi score was associated with larger frontal, parietal, occipital, and average lobar cortical thickness. Higher legume and fish intakes were associated with larger cortical thickness: legumes with larger superior parietal, inferior parietal, precuneus, parietal, occipital, lingual, and fish with larger precuneus, superior parietal, posterior cingulate, parietal, and inferior parietal. Higher carbohydrate and sugar intakes were associated with lower entorhinal cortical thickness.

Discussion

In this sample of elderly persons, higher adherence to MeDi was associated with larger cortical thickness. These cross‐sectional findings require validation in prospective studies.
Building a Knowledge to Action Program in Stroke Rehabilitation
Authors: Janzen Shannon , McIntyre Amanda , Richardson Marina , Britt Eileen , Teasell Robert
Published: July 2016

The knowledge to action (KTA) process proposed by Graham et al (2006) is a framework to facilitate the development and application of research evidence into clinical practice. The KTA process consists of the knowledge creation cycle and the action cycle. The Evidence Based Review of Stroke Rehabilitation is a foundational part of the knowledge creation cycle and has helped guide the development of best practice recommendations in stroke. The Rehabilitation Knowledge to Action Project is an audit-feedback process for the clinical implementation of best practice guidelines, which follows the action cycle. The objective of this review was to: (1) contextualize the Evidence Based Review of Stroke Rehabilitation and Rehabilitation Knowledge to Action Project within the KTA model and (2) show how this process led to improved evidence-based practice in stroke rehabilitation. Through this process, a single centre was able to change clinical practice and promote a culture that supports the use of evidence-based practices in stroke rehabilitation.
Needs–supplies fit and behavioral outcomes: The mediating role of organizational identification
Authors: Travaglianti Fabrice , Babic Audrey , Pepermans Roland , Hansez Isabelle
Published: July 2016

While it is well known that person–organization fit is an important antecedent of behavioral outcomes, little is known about needs–supplies fit in this relationship. In this way, we first want to extend our knowledge about defining and assessing work-related needs derived from employment quality indicators as the basis for needs–supplies fit. Second, following the Cognitive and Affective Personality System theory, we test the mediating role of organizational identification to better understand how needs–supplies fit is related to task performance and organizational citizenship behaviors. Data were collected in two companies: sample 1 (N=525) and sample 2 (N=525). Results show (a) that a specific needs–supplies fit perception (i.e., based on 12 work-related needs derived from employment quality indicators) is positively related to a global needs–supplies fit perception (i.e., based on an overall job perception), suggesting that needs–supplies fit may be a multidimensional concept and (b) the full mediating role of organizational identification in the relationship between needs–supplies fit and performance measures.
Engaging Students With Autism Spectrum Disorder in Research Through Participant-Driven Photo-Elicitation Research Technique
Authors: Danker Joanne , Strnadová Iva , Cumming Therese M.
Published: July 2016

Participant-driven photo-elicitation, a visual research technique, is commonly used with marginalised and vulnerable groups of individuals. Reflections on the use of this technique are illustrated through a study examining the conceptualisation of student wellbeing from the perspectives of teachers, parents, and students with autism spectrum disorder. Interviews were used to collect data from teachers and parents, while photovoice, a community and participatory action research strategy, was used as a data collection method for students. Although participant-driven photo-elicitation (a component of photovoice) requires much planning, resources, collaboration with teachers, and the flexibility of the researcher, it empowers and engages students with autism spectrum disorder, helps develop social, communication, and self-awareness skills, enables the collection of rich data, and enables the voices of these students to be heard.

Published: July 2016

Radiocarbon dating and Bayesian chronological modelling, undertaken as part of the investigation by theTimes of Their Livesproject into the development of Late Neolithic settlement and pottery in Orkney, has provided precise new dating for the Grooved Ware settlement of Barnhouse, excavated in 1985–91. Previous understandings of the site and its pottery are presented. A Bayesian model based on 70 measurements on 62 samples (of which 50 samples are thought to date accurately the deposits from which they were recovered) suggests that the settlement probably began in the later 32nd century calbc(with Houses 2, 9, 3 and perhaps 5a), possibly as a planned foundation. Structure 8 – a large, monumental structure that differs in character from the houses – was probably built just after the turn of the millennium. Varied house durations and replacements are estimated. House 2 went out of use before the end of the settlement, and Structure 8 was probably the last element to be abandoned, probably during the earlier 29th century calbc. The Grooved Ware pottery from the site is characterised by small, medium-sized, and large vessels with incised and impressed decoration, including a distinctive, false-relief, wavy-line cordon motif. A considerable degree of consistency is apparent in many aspects of ceramic design and manufacture over the use-life of the settlement, the principal change being the appearance, from c. 3025–2975 calbc, of large coarse ware vessels with uneven surfaces and thick applied cordons, and of the use of applied dimpled circular pellets. The circumstances of new foundation of settlement in the western part of Mainland are discussed, as well as the maintenance and character of the site. The pottery from the site is among the earliest Grooved Ware so far dated. Its wider connections are noted, as well as the significant implications for our understanding of the timing and circumstances of the emergence of Grooved Ware, and the role of material culture in social strategies.
EFFECTS OF SOIL CHARACTERISTICS AND DATE PALM MORPHOLOGICAL DIVERSITY ON NUTRITIONAL COMPOSITION OF PAKISTANI DATES

Published: July 2016

The use of date palm (Phoenix dactyliferaL.) has been closely connected with the survival of people in arid areas given their fruits´ high concentration of energy, fibre, minerals, vitamins and 16 amino acids. The arid climate and sandy or clayey loam soils in many parts of Pakistan are ideal for the cultivation of date palm, which contributes to feeding the country's rapidly growing population. To fill knowledge gaps on the effects of cultivar diversity and cultivation sites on the nutritional properties of dates, the present project studied dates and related physical and chemical soil properties across six districts in four provinces of Pakistan: Jhang, Muzaffargarh and Bahawalpur in Punjab; Dera Ismail Khan (D. I. Khan) in Khyber Pakhtunkhwa (KPK); Khairpur in Sindh and Panjgur in Baluchistan. To this end, during 2012–2013, a total of 170 households (HHs) were selected using a snowball sampling approach. Thirty-nine different date palm cultivars with diverse nutritional properties are grown in the study area. In these total soluble solids (TSS) were highest in Muzawati and Koharba cultivars, while cultivars and site conditions significantly affected TSS, minerals (calcium and magnesium), acidity, and firmness of dates. Concentration of CaCO3and bulk density (BD) of soils varied widely, while hydraulic conductivity (HC) was similar across sites (p= 0.128). Mean soil pH was highest in Panjgur (8.3) and lowest in Muzaffargarh (7.6), soil organic matter content was highest in Jhang (0.8%) and lowest in D. I. Khan (0.6%) and plant available phosphorous (P) was highest in Muzaffargarh (7.8 mg kg−1) and lowest in Panjgur (6.0 mg kg−1). As indicated by correlation analysis BD and cation exchange capacity of soils seemed to affect TSS, whereas concentration of CaCO3and available P were correlated with calcium concentration of dates. HC and electrical conductivity, however, seemed to have little effect on dates´ nutritional properties.
Notes on selected Cretaceous echinoids from south-central Sakhalin, Far East Russia
Authors: Jagt J.W.M. , Jagt-Yazykova E.A. , Zonova T.D.
Published: July 2016

From Albian, Santonian and Campanian strata in south-central Sakhalin, four echinoid taxa are described, illustrated and discussed. In Far East Russia, echinoids are rare constituents amongst mid- and Late Cretaceous macrofaunal assemblages in which inoceramid and non-inoceramid bivalves, plus heteromorph and non-heteromorph ammonites predominate. The sole regular species in the present lot is represented by an incomplete external mould of a primary spine of a rhabdocidarid,Polycidaris(?) sp., from the lower Campanian. Irregular taxa include a fragmentary, specifically indeterminate ‘pygurid’,Echinopygus(?) sp., of late Albian age, as well as two spatangoids. One of these, a toxasterid of late Campanian age, is assigned toNiponastercf.hokkaidensis(LambertinLambert & Thiéry, 1924). The other is a new hemiasterid with a semi-ethmophract apical disc, a peripetalous fasciole with diffuse boundaries (parafasciole) and posterior petals that are near-equal in length to anterior ones, from lowermost Campanian strata. For this, the namePalhemiaster natalyaen. sp. is introduced. Comparisons with coeval echinoid faunas from nearby Hokkaido (northern Japan) are hampered by the generally poor preservation of the latter. However, with the exception ofNiponastercf.hokkaidensis, none of the forms recorded in the present paper appears to be represented in those Japanese assemblages.
Variations in the morphology of porosity in the Boom Clay Formation: insights from 2D high resolution BIB-SEM imaging and Mercury injection Porosimetry

Boom Clay is considered as one of the potential host rocks for the disposal of high level and/or long lived radioactive waste in a geological formation in Belgium (Mol study site, Mol-1 borehole) and the Netherlands. The direct characterisation of the pore space is essential to help understand the transport properties of radionuclides in argillaceous materials.

This contribution aims to characterise and compare the morphology of the pore space in different Boom Clay samples, representing end-members with regard to mineralogy (i.e. clay content) and grain-size distribution of this formation. Broad ion beam (BIB) cross-sectioning is combined with SEM imaging of porosity and Mercury injection Porosimetry (MIP) to characterise the variability of the pore space in Boom Clay at the nm- to μm-scale within representative 2D areas and to relate microstructural observations to fluid flow properties of the bulk sample material. Segmented pores in 2D BIB surfaces are classified according to the mineralogy, generating representative datasets of up to 100,000 pores per cross-section.

Results show total SEM-resolved porosities of 10-20% and different characteristic mineral phase internal pore morphologies and intra-phase porosities.

Most of the nano-porosity resides in the clay matrix. In addition, in the silt-rich samples, larger inter-aggregate pores contribute to a major part of the resolved porosity. Pore-size distributions within the clay matrix suggest power-law behaviour of pore areas with exponents between 1.56-1.74. Mercury injection Porosimetry, with access to pore-throat diameters down to 3.6 nm, shows total interconnected porosities between 27-35 Vol.-%, and the observed hysteresis in the MIP intrusion vs. extrusion curves suggests relatively high pore-body to pore-throat ratios in Boom Clay. The difference between BIB-SEM visible and MIP measured porosities is explained by the resolution limit of the BIB-SEM method, as well as the limited size of the BIB-polished cross-section areas analysed. Compilation of the results provides a conceptual model of the pore network in fine- and coarse-grained samples of Boom Clay, where different mineral phases show characteristic internal porosities and pore morphologies and the overall pore space can be modelled based on the distribution of these mineral phases, as well as the grain-size distribution of the samples investigated.

We investigated the Quaternary lithological succession and faunas in a borehole near Moriaanshoofd (Province of Zeeland, SW Netherlands), in order to improve our understanding of the depositional context of classical Gelasian mammal faunas from the region. The fossils mostly derive from the base of a fossil-rich interval between 31 m and 36.5 m below the surface, that was initially interpreted as a Middle or Late Pleistocene interglacial marine unit, but turned out to be a Late Quaternary fluvial unit with large amounts of reworked fossils and sediments. Eocene mollusc taxa pinpoint Flanders (Belgium) as the source region for this river. Within the base of this paleo-Schelde River fossil material of various stratigraphic provenance became incorporated.
Exploration in the Netherlands, 1987-2012

Published: July 2016

Following a time of expansion of the oil industry, the period 1987-2012 and especially the second half of it reflects a diversification of exploration activities in the Netherlands. In addition to the ongoing discovery of classical hydrocarbon reservoirs, successful attempts have been made to explore deep geothermal energy. Shale gas and Coal Bed Methane received interest in the Netherlands too but so far no wells have been drilled in order to test the potential. Storage of gas and liquids has been introduced and salt mining more or less continued without many changes. In terms of drilling activity, the last 25 years show a decreasing trend and the discovered volumes are smaller. Testing of new play concepts was either successful (shallow gas) or not (Dinantian) and sometimes an unexpected discovery was made (Triassic Fat Sands). New techniques proved older fields to be exploitable again, e.g. redevelopment of the Schoonebeek Field. Therefore, despite a decline in number of wells drilled and reserves added, the diversification of use of the subsurface will guarantee ongoing exploration.
Thin- and thick-skinned salt tectonics in the Netherlands; a quantitative approach
Authors: ten Veen J.H. , van Gessel S.F. , den Dulk M.
Published: July 2016

The Zechstein salt in the Dutch part of the North Sea Basin played a key role in the generation of successful petroleum plays. This is not only because of its sealing capacity, but also because the salt occurs in structures that provide lateral and vertical traps. The structural styles of areas with thick salt and those with none- or thin salt are completely different during phases of extensional or compressional tectonics. This indicates that, indirectly, the depositional thickness of the main Zechstein salt is essential in regulating the loci of the Dutch petroleum systems. In this paper we aim at quantifying current ideas on the relationship between 1) depositional salt thicknesses; 2) structural style of the main structural elements identified in the Dutch subsurface; 3) timing of deformation; and 4) thickness of the overburden. By finalisation of TNO's subsurface mapping program (see Kombrink et al., this issue), several data products are available that allow evaluation of these relationships. The depositional thickness of the salt was estimated using iterative smoothing of the present day thickness, the results of which account both for regional thickness variations and volume preservation (99%). Fault-distribution analysis shows that faults are only able to penetrate salt with a depositional thickness of <300 m, a transition that demarcates the division between thin- and thick-skinned salt tectonics. In the southern offshore where the salt is thin or absent, the overburden shows the same fault pattern throughout the stratigraphic sequence. In the northern realm, where salt is thicker than 300 m, the salt layer acted as decollement and sub- and supra salt strain are dissimilar. A strong genetic and temporal relationship exists between periods of regional tectonism, halokinetic intensity and thickness distribution of the Zechstein overburden. This relationship is further proven by burial history analysis across two selected profiles in the northern offshore. The analysis focuses on the vertical distribution of the salt by taking into account the depositional and erosional history of the salt overburden, without a-priori defined periods of salt flow. The results corroborate the notion that platforms and highs experienced less extension during the major phases of Jurassic rifting and further suggest that the absence of a thick Jurassic overburden precludes major salt flow during this tectonic phase. Main salt flow was triggered during the Sub-Hercynian and later phases of compression resulting in salt pillow geometries. In the basinal areas, where the Jurassic succession is thickest, salt diapirs and walls formed that are almost exclusively linked to major subsalt faults. Main salt flow occurred during Late Kimmerian rifting, whereas some minor structuration occurred during Sub-Hercynian inversion.
Pressure and fluid dynamic characterisation of the Dutch subsurface

This paper presents and discusses the distribution of fluid and leak-off pressure data from the subsurface of onshore and offshore Netherlands in relation to causes of formation fluid overpressure and the permeability framework. The observed fluid pressure conditions demonstrate a clear regional difference between the southern and the north and north-eastern part of the study area. In the southern area, formation fluid pressures are close to normal and well below measured leak-off pressures. In the north, formation fluids are overpressured and may locally even approach the measured leak-off pressures. The regional differences in fluid overpressure can, in large part, be explained by differences in geologic framework and burial history. In the south, relatively low rates of sedimentary loading and the presence of relatively permeable sedimentary units have led to the currently observed normally pressured conditions. In the northern area, relatively rapid Neogene sediment loading plays an important role in explaining the observed overpressure distributions in Cenozoic mudstones, Cretaceous Chalk and Rijnland groups, and probably also in Jurassic units. The permeability framework of the northern and north-eastern area is significantly affected by Zechstein and Triassic salt deposits and structures. These units are characterised by very low permeability and severely restrict fluid flow and pressure dissipation. This has created hydraulically restricted compartments with high overpressures (for example overpressures exceeding 30 MPa in the Lower Germanic Trias Group in the Terschelling Basin and Dutch Central Graben).
Subsurface temperature of the onshore Netherlands: new temperature dataset and modelling

Subsurface temperature is a key parameter for geothermal energy prospection in sedimentary basins. Here, we present the results of a 3D temperature modelling using a thermal-tectonic forward modelling method, calibrated with subsurface temperature measurements in the Netherlands. The first step involves the generation of a coherent dataset of temperature values for the calibration of the model. In the Netherlands, most of the available measurements (98.8%) are BHT measurements and therefore need to be corrected from the thermal perturbation created during drilling. The remaining 1.2% is composed of DST measurements, which closely resemble the formation temperature (i.e., ±5 °C). The resulting dataset, after correction, gives a total number of 1293 values in 454 wells. Included in this dataset are 412 highly reliable values corrected with the Instantaneous Cylinder Source (ICS) method and 829 values of a lower reliability corrected with the AAPG method. In addition to the corrected values, 52 DST values in 26 wells are available from the Dutch subsurface. The average thermal gradient of this whole dataset is 31.3 °C/km with a surface temperature of 10.1 °C. The second step in the modelling process was the generation of a 3D forward model that focuses on calculating the temperature distribution of the sedimentary basin fill, taking into account the basin evolution of the past 20 Myrs and thermal properties and processes of the whole lithosphere. From the 3D thermal model, we extracted 2D cross sections across well locations to compare model temperatures with calibration data. Furthermore, we present vertical profiles, isodepth maps and temperature projection on geological layers, to discuss the relationship between temperature and geology. Anomalies in this relationship can have several causes and include: 1) the extreme thermal conductivity and complex geometry of the Zechstein salt; 2) enhanced radiogenic heat production of the upper crust due to magmatic intrusions. In addition, our model supports earlier findings that shallow hydrothermal convection in highly permeable sediments can effectively lower thermal conductivity and temperatures in shallow sediments.
