Abstract. Trees, the most successful biological power plants on earth, build and plumb the critical zone (CZ) in ways that we do not yet understand. To encourage exploration of the character and implications of interactions between trees and soil in the CZ, we propose nine hypotheses that can be tested at diverse settings. The hypotheses are roughly divided into those about the architecture (building) and those about the water (plumbing) in the CZ, but the two functions are intertwined. Depending upon one's disciplinary background, many of the nine hypotheses listed below may appear obviously true or obviously false. (1) Tree roots can only physically penetrate and biogeochemically comminute the immobile substrate underlying mobile soil where that underlying substrate is fractured or pre-weathered. (2) In settings where the thickness of weathered material, H, is large, trees primarily shape the CZ through biogeochemical reactions within the rooting zone. (3) In forested uplands, the thickness of mobile soil, h, can evolve toward a steady state because of feedbacks related to root disruption and tree throw. (4) In settings where h ≪ H and the rates of uplift and erosion are low, the uptake of phosphorus into trees is buffered by the fine-grained fraction of the soil, and the ultimate source of this phosphorus is dust. (5) In settings of limited water availability, trees maintain the highest length density of functional roots at depths where water can be extracted over most of the growing season with the least amount of energy expenditure. (6) Trees grow the majority of their roots in the zone where the most growth-limiting resource is abundant, but they also grow roots at other depths to forage for other resources and to hydraulically redistribute those resources to depths where they can be taken up more efficiently. (7) Trees rely on matrix water in the unsaturated zone that at times may have an isotopic composition distinct from the gravity-drained water that transits from the hillslope to groundwater and streamflow. (8) Mycorrhizal fungi can use matrix water directly, but trees can only use this water by accessing it indirectly through the fungi. (9) Even trees growing well above the valley floor of a catchment can directly affect stream chemistry where changes in permeability near the rooting zone promote intermittent zones of water saturation and downslope flow of water to the stream. By testing these nine hypotheses, we will generate important new cross-disciplinary insights that advance CZ science.
Mechanisms of variability in decadal sea-level trends in the Baltic Sea over the 20th century

Published: November 2017

Abstract. Coastal sea-level trends in the Baltic Sea display decadal-scale variations around a long-term centennial trend. In this study, we analyse the spatial and temporal characteristics of the decadal trend variations and investigate the links between coastal sea-level trends and atmospheric forcing on a decadal timescale. For this analysis, we use monthly means of sea-level and climatic data sets. The sea-level data set is composed of long tide gauge records and gridded sea surface height (SSH) reconstructions. Climatic data sets are composed of sea-level pressure, air temperature, precipitation, evaporation, and climatic variability indices. The analysis indicates that atmospheric forcing is a driving factor of decadal sea-level trends. However, its effect is geographically heterogeneous. This impact is large in the northern and eastern regions of the Baltic Sea. In the southern Baltic Sea area, the impacts of atmospheric circulation on decadal sea-level trends are smaller. To identify the influence of the large-scale factors other than the effect of atmospheric circulation in the same season on Baltic Sea sea-level trends, we filter out the direct signature of atmospheric circulation for each season separately on the Baltic Sea level through a multivariate linear regression model and analyse the residuals of this regression model. These residuals hint at a common underlying factor that coherently drives the decadal sea-level trends in the whole Baltic Sea. We found that this underlying effect is partly a consequence of decadal precipitation trends in the Baltic Sea basin in the previous season. The investigation of the relation between the AMO index and sea-level trends implies that this detected underlying factor is not connected to oceanic forcing driven from the North Atlantic region.

Published: November 2017

Abstract. The Gravity Recovery and Climate Experiment (GRACE) mission has yielded data on the Earth's gravity field to monitor temporal changes for more than 15 years. The GRACE twin satellites use microwave ranging with micrometre precision to measure the distance variations between two satellites caused by the Earth's global gravitational field. GRACE Follow-on (GRACE-FO) will be the first satellite mission to use inter-satellite laser interferometry in space. The laser ranging instrument (LRI) will provide two additional measurements compared to the GRACE mission: interferometric inter-satellite ranging with nanometre precision and inter-satellite pointing information. We have designed a set of simulated GRACE-FO data, which include LRI measurements, apart from all other GRACE instrument data needed for the Earth's gravity field recovery. The simulated data files are publicly available via https://doi.org/10.22027/AMDC2 and can be used to derive gravity field solutions like from GRACE data. This paper describes the scientific basis and technical approaches used to simulate the GRACE-FO instrument data.

Neste trabalho foi realizada uma avaliação da variação dimensional de corpos de prova (cp) de argamassa moldados com diferentes tipos de cimento submetidos ao ataque ácido de agentes compostos de enxofre. Dentre os corpos de prova moldados, foram utilizados três tipos diferentes de cimento, sendo que esses foram cimento Portland (CP) II Z, CP IV-32 RS e CPV. Os ensaios foram realizados submetendo parte dos cp à solução de sulfato de sódio, outra parte dos cp em ácido sulfúrico e a terceira parte em solução de água saturada com cal, para referência. Após a cura dos cp, foi realizada a medida inicial dos mesmos em um relógio comparador e posterior imersão dos mesmos nas soluções. As medições para avaliar a variação dimensional foram realizadas aos 14, 28, 51, 58, 63, 72, 79 e 95 dias. O tipo de cimento que apresentou maior variação dimensional foi o CP II-Z, sendo a menor do CP IV 32 RS, entretanto, ao longo das medições, principalmente nas primeiras idades, não foi observada apenas expansão relativa à solução de referência de água saturada com cal. Como principal contribuição da pesquisa ressalta-se a importância da especificação de materiais como argamassas resistentes ao ataque por ácido sulfúrico.
Abstract
In this paper, an evaluation of the dimensional variation of mortar specimens molded with different types of cement subjected to acid attack of composite sulphur agents. Among the molded specimens, three different types of cement were used, and these were CP II Z, CP IV-32 RS and CPV. The tests were carried out by submitting part of the test specimens to the sodium sulfate solution, another part of the test specimens in sulfuric acid and the third part in solution of calcined water for reference. After the curing time of the specimens, the initial measurement of the specimens was carried out in a comparator watch and subsequent immersion in the solutions. Measurements to evaluate the dimensional variation were performed at 14, 28, 51, 58, 63, 72, 79 e 95 days. The type of cement that presented the largest dimensional variation was the CP II-Z, being the smaller of the CP IV 32 RS, however, along of the measurements, especially in the early ages, did not observe only expansion relative to the reference solution of saturated water with lime

Introduction: The use of phosphate binders to control hyperphosphatemia may allow diets less restricted in protein and calories for maintenance hemodialysis (MHD) patients. The study compared intakes of protein, calorie and phosphate among MHD patients with different serum phosphate concentrations, taking into account binder use. The hypothesis was that low serum phosphate would be associated with low intakes of protein and calories only in patients not on binders. Methods: A cross-sectional study of 443 patients enrolled in the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO) in Salvador, Brazil, with stratified sampling on serum phosphate: ≤3.0 (n = 41), 3.5-5.5 (n = 328) and ≥7.0 mg/dL (n = 74). A 3-day diet diary was used to determine dietary intakes. Results: Approximately 49.0% confirmed binder use. Covariate-adjusted linear regression showed that associations between dietary intakes and serum phosphate were modified by the binder use. In patients not on binders, protein intake was >20% lower for serum phosphate ≤3.0 mg/dL compared to higher concentrations. Also in those not on binders, calorie intake was >30% lower for serum phosphate ≤3.0 mg/dL compared to ≥7.0 mg/dL. Differences in dietary intakes by serum phosphate were virtually absent in patients on binders. Conclusions: The results are consistent with the hypothesis that low serum phosphate is associated with low protein and calorie intake only among MHD patients not on binders. This study supports recommendations to prevent hyperphosphatemia in MHD patients by adequate combination of binder use and selection of foods restricted in phosphors but not severely restricted in protein and calories.
Predictive Biomarkers May allow Precision Therapy of Endometriosis

Published: November 2017

Introduction Endometriosis is a chronic inflammatory gynecological disorder that causes pelvic pain. Due to the heterogeneity of the disease, response to any treatment in an individual is variable. We aimed to develop in vitro testing that could be adapted for use in precision therapy for endometriosis. We piloted a personalized medicine approach by identifying predictive biomarkers while determining the effect of bazedoxifene (BZA) and medroxyprogesterone acetate (MPA) on the gene expression of a progesterone receptor (PR), an estrogen receptor (ER), and an aromatase (CYP19A1) enzyme in cells cultured from biopsies of endometriosis patients. The differential expression of the most common molecular targets in endometriosis therapy correlated with cellular response. Methods Primary eutopic endometrial stromal cells were cultured from endometrial biopsies obtained in secretory phase from women between 24 and 42 years old with moderate-to-severe endometriosis (stages III and IV). Exclusion criteria included use of hormonal treatments and intrauterine contraception in the 6 months prior to surgery. Cells were treated either with BZA, MPA, or vehicle control. Total RNA was extracted from the treated and untreated cells. Differential expression of genes that are involved in the pathogenesis of endometriosis was determined by quantitative reverse transcriptase-polymerase chain reaction analysis. Results After determining the baseline expression levels of PRA/B, ERα and CYP19A1, response to treatment was monitored using Ki-67 as a marker of cell proliferation. MPA was effective in blocking proliferation in the group expressing high levels of PRA/B. Endometrium expressing high levels of CYP19A1 preferentially responded to BZA, a selective estrogen receptor modulator known to block estrogen action in endometrium. Conclusions PR expression may predict progestin resistance in endometriosis while CYP19A1 expression may indicate the need to block estrogen signaling.
Use of bovine carotid artery for buttonhole technique hemodialysis
Authors: Schuman Earl , Alexander Philip , Ronfeld Amy 
Published: November 2017

Purpose: Assess the feasibility of using a bovine carotid artery graft for buttonhole technique hemodialysis in patients who are not candidates for a native fistula. Methods: Case reports used to demonstrate selection criteria and results for this approach. Criteria include: knowledgeable patient with prior dialysis experience, stable graft in place for 3 months minimum, not a candidate for a native fistula, and able to maintain close follow-up. Results: Both grafts were based on axillary vessels and have been in place for a total of 64 months. They have been used for dialysis via buttonhole for a total of 40 months. There have been three procedures on these patients, post-buttonhole use (.87/year). There have been no infections. Conclusions: These patients were carefully selected based on desire, support, knowledge/experience and ability. Their success suggests that buttonhole technique for hemodialysis on a synthetic semi-biologic graft can be accomplished with morbidity and longevity similar to any graft using non-buttonhole needle access.
An arterioarterial prosthetic graft as an alternative option for haemodialysis access: a systematic review
Authors: Grima Matthew J. , Vriens Bianca , Holt Peter J. , Chemla Eric 
Published: November 2017

Introduction: All arteriovenous fistula/grafts options should be exhausted before haemodialysis is carried out via central venous catheters (CVC). CVCs carry high morbidity and mortality risks and in some patients, the central veins could be exhausted. In these patients, an arterioarterial prosthetic loop (AAPL) or straight graft can be the only option for haemodialysis. A systematic review was thus carried out to look at the use of arterioarterial graft for haemodialysis, with regards to dialysis adequacy, complications, and patency rates. Methods: An electronic search was performed using the EMBASE and MEDLINE databases from inception until June 2017. Study retrieval was conducted according to PRISMA guidelines. Results: A total of eight studies published between 1976 and 2017 were identified for pooled analysis. The studies were retrospective cohort in design and reported data on 151 patients. Primary patency rate ranged from 67%-94.5% at six months to 54%-61% at 36 months, with secondary patency rates from 83%-93% at six months to 72%-87% at 36 months. All studies documented satisfactory haemodialysis. Although limited by the size of the cohort of patients studied, patients with end-to-side grafts did not suffer from distal ischaemia when the graft occluded unlike patients who had their graft sutured as end-to-end. Conclusions: This review highlights the potential benefit of arterioarterial grafts for dialysis as an alternative vascular access option. As a result, this review calls for registry-based multicentre study to evaluate this treatment arm as an alternative option when all AVF/AVG options are exhausted.

Objective: To investigate the feasibility and safety of the peripherally inserted central catheters (PICCs) accessed via the superficial femoral vein in patients with superior vena cava syndrome (SVCS). Methods: From October 2010 to December 2014, 221 cancer patients with SVCS in our center received real-time ultrasound-guidance of the superficial femoral vein inserted central catheters (FICCs) at the mid-thigh. PICC insertion via upper extremity veins had also been investigated in 2604 cancer patients without SVCS as control. The average catheterization time, one-time puncture frequency, catheter duration and complications were compared between two groups. Results: In the FICC group, the mean catheterization time was 31.60 ± 0.15 minutes, one-time puncture frequency was 1.05 ± 0.08, and catheter duration was 168.95 ± 20.47 days. There was no significant difference compared with the upper extremity veins PICC group: 31.11 ± 3.86 minutes, 1.03 ± 0.30, and 173.58 ± 39.81 days, respectively. The major complications included skin allergy to chlorhexidine gluconate (CHG) dressings, exudation, catheter-related infection, catheter occlusions, unplanned catheter withdrawal, venous thrombosis, mechanical phlebitis, and catheter malposition. It is interesting that a higher rate of catheter malposition was observed in the upper extremity veins PICC group than in the FICC group (2.15% vs. 0.00%). There were no significant differences in other complications between the two groups. Conclusions: Real-time ultrasound-guided PICCs accessed via the superficial femoral vein at the mid-thigh is a new modified technique with low complications, which can be a feasible and safe alternative venous access for patients with SVCS.
Intracapsular Carcinoma Ex-Pleomorphic Adenoma of the Parapharyngeal Space: Report of Two Cases and Review of the Literature
Authors: Accorona Remo , Barbieri Diego , Farina Davide , Lombardi Davide , Bussi Mario , Nicolai Piero 
Published: November 2017

Background Carcinoma ex-pleomorphic adenoma of the parapharyngeal space is an exceedingly rare entity. Methods The clinical records of two patients with primary carcinoma ex-pleomorphic adenoma of the parapharyngeal space surgically treated at two different centers were retrospectively analyzed. Results Despite ultrasound-guided fine-needle aspiration cytology and magnetic resonance imaging, the correct diagnosis was preoperatively missed in both cases. Excision was obtained through a transcervical-transparotid approach in 1 case and a minimally-invasive endoscopic-assisted transcervical approach in the other. Definitive histology was consistent with intracapsular carcinoma ex-pleomorphic adenoma. Adjuvant radiotherapy was performed in the case with macroscopic malignant degeneration; both patients are alive and free from disease 36 months after surgery. Conclusions Carcinoma ex-pleomorphic adenoma of the parapharyngeal space is a rare disease, and definitive diagnosis may be challenging. Surgery is the mainstay of treatment, but adjuvant radiotherapy also may be required in the presence of specific risk factors.
Remarks on Convolutions and Fractional Derivative of Distributions
Authors: Li Chenkuan , Clarkson Kyle 
Published: November 2017

This paper begins to present relations among the convolutional definitions given by Fisher and Li, and further shows that the following fractional Taylor's expansion holds based on convolution \[ \frac{d^\lambda}{d x^\lambda} \theta (x) \phi(x) = \sum_{k = 0}^{\infty} \frac{\phi^{( k)}(0)\, x_+^{k - \lambda }}{\Gamma(k - \lambda + 1)} \quad \mbox{if} \quad \lambda \geq 0, \] with demonstration of several examples. As an application, we solve the Poisson's integral equation below \[ \int_0^{\pi/2} f(x \cos \omega)\sin^{2 \lambda + 1} \omega d \omega = \theta(x) g(x) \] by fractional derivative of distributions and the Taylor's expansion obtained.
