Performance of the dynamically dimensioned search algorithm: influence of parameter initialization strategy when calibrating a physically based hydrological model
Authors: Lespinas Franck , Dastoor Ashu , Fortin Vincent 
Published: November 2017

AbstractThis study presents an evaluation of the performance of the dynamically dimensioned search (DDS) algorithm when calibrating the hydrological component of the Visualizing Ecosystems for Land Management Assessments (VELMA) ecohydrological model. Two calibration strategies were tested for the initial parameter values: (1) a ‘high-cost strategy’, where 100 sets of initial parameter values were randomly chosen within the overall parameter space, and (2) a ‘low-cost strategy’, where a unique set of initial parameter values was derived from the available field data. Both strategies were tested for six different values of the maximum number of model evaluations ranging between 100 and 10,000. Results revealed that DDS is able to converge rapidly to a good parameter calibration solution of the VELMA hydrological component regardless of the parameter initialization strategy used. The accuracy and convergence efficiency of the DDS algorithm were, however, slightly better for the low-cost strategy. This study suggests that initializing the parameter values of complex physically based models using information on the watershed characteristics can increase the efficiency of the automatic calibration procedures.

Abstract
The objective of this study was to monitor the degradation and obtain the mineralization fraction of anaerobically digested sludge, also known as digestate, under field conditions, when applied to the surface or incorporated into the soil. Sludge was applied to a dystrophic Inceptisol at a dose of 500 kg ha–1 yr–1 of total nitrogen, where the monitoring period of the mineralization process lasted 131 days. Samples of the soil-residue mixture were collected for analysis of the total organic carbon (TOC) and easily oxidizable organic carbon (OOC), total, ammonia, nitrate and organic nitrogen (ON). The annual mineralization fractions of the digestate, estimated based on the difference between the initial and final contents of TOC, OOC and ON in samples of the material collected, were 99.5 and 100%, respectively, when incorporated with the soil or applied to the soil surface.

Published: November 2017

AbstractThe problem of biological invasions attributed to ballast water release is an ongoing problem that threatens ecosystems and human health. Ultraviolet (UV) radiation has been increasingly used for ballast water treatment mainly due to the advantages of short contact time and minimized harmful disinfection by products. In this study, the impact of salinity on the inactivation of Vibrio cholerae (NCTC 7253) was examined, and comparison of inactivation level and disinfection kinetics after medium-pressure (MP) (1 kW) and low-pressure (LP) (10 W) UV irradiation was made. MP UV exposure resulted in higher inactivation efficacy against V. cholerae than LP UV exposure especially at lower UV doses (≤3 mJ cm−2) and salinity had a negative impact on both MP and LP UV disinfection, especially at higher UV doses (≥3 mJ cm−2 for MP and ≥4 mJ cm−2 for LP). To understand the mechanisms of salinity effect on V. cholerae, the enzyme-linked immunosorbent assay (ELISA) was employed to determine the number of cyclobutane pyrimidine dimers (CPDs), one major type of DNA damage. No significant effects of salinity were found at the CPDs level except for 3% artificial seawater after LP UV exposure case. It is imperative that site-specific conditions of salinity be taken into account in the design of UV reactors to treat V. cholerae and other species.
Initial conditions of urban permeable surfaces in rainfall-runoff models using Horton's infiltration

Published: November 2017

Abstract
Infiltration is a key process controlling runoff, but varies depending on antecedent conditions. This study provides estimates on initial conditions for urban permeable surfaces via continuous simulation of the infiltration capacity using historical rain data. An analysis of historical rainfall records show that accumulated rainfall prior to large rain events does not depend on the return period of the event. Using an infiltration-runoff model we found that for a typical large rain storm, antecedent conditions in general lead to reduced infiltration capacity both for sandy and clayey soils and that there is substantial runoff for return periods above 1–10 years.
Tales of the Unexpected in Synthesis of Polyfunctional Heteroaromatics
Authors: Moustafa Moustafa S. , Al-Mousawi Saleh M. , El-Seedi Hesham R. , Elnagdi Mohamed H. 
Published: November 2017

Background:
Our research group has a longstanding interest in the synthesis of novel functionalized
heteroaromatic compounds, and the development of new methods for this purpose. During our ongoing investigations,
we recently had an instance to check the reproducibility of some published results concerning the
chemistry of arylhydrazonals, enamines and other functionally substituted carbonyl compounds. This work has
led to the discovery of some new rearrangements, and the revision of the structures originally assigned to several
molecules.

Objective:
This review surveys some correction of several erroneous reports that have appeared in the literature,
and presents some interesting new rearrangements discovered in the course of investigating older reports.

Results:
The crystallographic studies revealed that the condensation of arylhydrazonals with active methylenenitriles
yields arylazoniconates rather than pyridazenones as previously reported. Additionally, phenathylthiocyanate
reacts with malononitrile to afford thiazoles rather than the previously reported condensation
with the carbonyl group. In another example, the reaction of phenethylmalononitrile with hydrazine yields
pyrazolopyridazenes rather than phenacylpyrazol-3,5-diamine. In yet another case, several interesting Dimrothtype
rearrangements were observed when malononitrile was condensed with enaminones, contradicting earlier
reports. Unexpectedly, these enaminones underwent self-trimerization to yield 1,3,5-trisubstituted benzenes
under certain conditions. Enaminonitriles also undergo interesting and novel Dimroth rearrangements when
reacted with cyclohexanedione or dehydroacetic acid derivatives.

Conclusion:
We have shown that the structures of several complex heterocyclic compounds that have been reported
in the literature over the last 50 years were incorrectly assigned, possibly because the authors who originally
reported them were using substandard or outdated analytical equipments.
Barnidipine Real-Life Efficacy and Tolerability in Arterial Hypertension: Results from Younger and Older Patients in the BASIC-HT Study
Authors: Lins Robert , De Vries Caroline 
Published: November 2017

Objective:
The aim of this study was to compare the efficacy and tolerability of barnidipine, a strong lipophilic calcium channel blocker, in younger (≤55 for efficacy or <65 years for adverse events) versus older (>55 or ≥65 years) patients with uncomplicated hypertension.

Methods:
20,275 patients received barnidipine, 10 or 20 mg/day, as monotherapy or in combination with other antihypertensive drug(s) in the observational BArnidipine real-life Safety and tolerability In Chronic HyperTension (BASIC-HT) study. Efficacy and tolerability were assessed over a 3-month period. The present paper describes results from prespecified subgroup analyses by age not reported elsewhere.

Results:
Both age groups showed a clinically meaningful decrease in blood pressure (BP) over time (p<0.0001). The mean systolic and diastolic BP after approximately 3 months of barnidipine therapy was well below the target value of <140/90 mmHg for individual patients, with no notable differences between age groups. The decrease in mean pulse pressure was greater in patients >55 years (-10.8 mmHg) than in patients ≤55 years (-8.7 mmHg) (p<0.0001) and the proportion of patients with pulse pressure >60 mmHg decreased from 61.1% at baseline to 24.8% at Visit 3 in patients >55 years and from 47.7% to 16.5% in patients ≤55 years (p<0.0001).
The overall incidence of adverse events was low, leading to treatment discontinuation in only 3.0-3.6% of patients. Peripheral edema, a common adverse effect with calcium channel blockers in clinical practice, was reported by 2.7% of patients aged <65 years and by 4.6% of patients aged ≥65 years.

Conclusion:
The efficacy and tolerability profiles of barnidipine as monotherapy or in combination with other antihypertensive drugs were shown to be favorable in both younger and older patients in a real-life practice setting. Randomized double-blind controlled studies are needed to confirm these results.

Las cianobacterias son procariotas fotoautótrofos, morfológica y molecularmente diversas, en las cuales se han reportado avances biotecnológicos sobre fijación de nitrógeno, biorremediación y valor nutricional-farmacéutico. La identificación tradicional de cianobacterias basada en morfología puede ser imprecisa, por lo que las técnicas moleculares son una herramienta robusta para el posicionamiento taxonómico de estas cepas tropicales. Este estudio se enfoca en la identificación morfológica y caracterización molecular de cianobacterias de ambientes tropicales de Costa Rica, para perspectivas biotecnológicas futuras. Las cepas fueron cultivadas en medio BG0-11, fotografiadas en microscopio de luz y clasificadas a nivel de género. La identificación molecular se llevó a cabo utilizando cebadores del gen ARN polimerasa ADN-dependiente (rpoC1) y la subunidad pequeña ARN ribosomal (16S ARNr). Seguidamente, se realizó un análisis de posicionamiento filogenético mediante alineamiento múltiple con MAFFTv.7 y máxima-verosimilitud con raxMLGUI. Basados en características fenotípicas, se identificaron cuatro géneros de cianobacterias Nostocales: Calothrix sp., Tolypothrix sp., Scytonema sp. y Nostoc sp. Los géneros identificados son conocidos por su capacidad de fijación de nitrógeno y potencial nutricional, farmacológico e industrial. Con una identificación exitosa de cianobacterias de ambientes tropicales, es posible continuar con más estudios de sus propiedades biotecnológicas y evaluar su potencial, con perspectivas futuras de aplicación y conservación de la biodiversidad.
¿Afecta los proyectos hidroeléctricos a las plantas acuáticas? El caso de Marathrum foeniculaceum (Podostemaceae) en dos ríos del sureste de Costa Rica
Authors: Arias Campos Luis Diego 
Published: November 2017

En los últimos años se están presentando fenómenos naturales que generan fuertes e intempestivos cambios de caudal en los ríos, por ejemplo la aparición cada vez más frecuente de El Niño y La Niña, pero uno de los principales factores antrópicos son los proyectos hidroeléctricos y entre los organismos afectados se encuentra la especie Marathrum foeniculaceum. Para evaluar los potenciales efectos de cambios anómalos del caudal simulé los cambios de caudal mediante cambios de posición de rocas (emergidas y sumergidas) en el río Unión y el río Convento, Costa Rica. Estudié el comportamiento fenológico de 1 260 individuos en seis rocas por río, en tres repeticiones (2013, 2014 y 2015). La floración se abrevió, debido a la correlación entre el cambio de humedad, el avance de la marchitez, el avance de las fenofases y la floración. La fructificación tardó más tiempo, sin correlación con parámetros ambientales. En promedio, la duración desde los botones florales hasta la apertura de los frutos fue de 20 días, mientras que naturalmente se puede extender por varios meses de la estación seca. El promedio de flores por individuo fue menor a dos, mientras que en condiciones naturales casi siempre es mayor a cinco. El éxito reproductivo fue menor a 30%; alrededor de 60% menos que en las condiciones naturales. Los frecuentes cambios de caudal implicaron la muerte de las plantas en menos de 13 días. Debido a que el período reproductivo es estacional, estos cambios de caudal durante el resto del año provocan la muerte de las plantas sin dejar descendencia (semillas), demostrando uno de los efectos adversos y subestimados de los proyectos hidroeléctricos sobre los ecosistemas acuáticos.

Published: November 2017

El algarrobo blanco (Prosopis alba G.) es una especie nativa de la región fitogeográfica del Chaco Occidental. Pese a que es considerada tolerante a la salinidad, los mecanismos fisiológicos que le confieren dicha característica no han sido dilucidados. Este trabajo tuvo como objetivo evaluar el impacto del estrés salino sobre la nutrición mineral y la fotosíntesis, en plántulas de algarrobo blanco. Las plántulas se cultivaron hidropónicamente con o sin la suplementación de 500 mM de NaCl. Se realizaron mediciones de emisión de fluorescencia de la clorofila a, y se cuantificaron las concentraciones de Na+, K+, Cl-, NO3- y la actividad nitrato reductasa (ANR). Luego de 7 días de tratamiento se determinó la biomasa de raíces y hojas. Se utilizó un diseño experimental completamente aleatorizado, con 10 repeticiones y los datos se analizaron con ANOVA y Test de Tukey. El estrés salino inhibió el crecimiento de la parte aérea y no afectó el crecimiento radicular. La salinidad aumentó las concentraciones foliares de Na+ y Cl-, y disminuyó las concentraciones de K+ y NO3- y la ANR. También se observó una disminución en los valores de qP, Fv/Fm y ETR, con un aumento en NPQ, demostrando que el estrés salino produjo fotoinhibición.

Published: November 2017

Tilapia is the second most important cultured species in the world fish culture but it can be affected by parasites. We conducted a cross-sectional parasitic study in tilapia larvae during sexual reversion for two seasons in Costa Rica. A total of 320 larvae from a concrete pond were necropsied and we found ten parasite species: Ichtyobodo sp., Apiosoma sp., Chillodonella sp., Heteropollaria sp., Trichodina sp., Dactylogyrus sp., Girodactylus sp., Centrocestus sp., lasidies and glochidies (two larval forms). These were classified in five taxonomic groups (two subtypes of protozoa, two metazoan classes and a type of mollusk). Protozoans and monogeneans (except Trichodina sp.) had a higher prevalence in the rainy season, when water had more solid waste, while digeneans and molluscs were more prevalent in the dry season, with different infection dynamics over gills, skin, fins and head.

Kemunculan minyak bumi di permukaan ada dua kategori, yaitu : rembesan (seepages, seeps) yang aktif, dimana minyak mengalir bersama-sama air dan rembesan yang sudah tidak aktiv dimana minyak yang sudah menjenuhi batuan dan fraksi ringan nya sudah menguap ke permukaan. Rembesan ini terkumpul di permukaan dan biasanya tidak ekonomis, tetapi dari sisi explorasi adanya rembesan ini akan memberikan informasi bahwa ada sumber minyak di bawah permukaan. Adanya kemunculan seepages di salah satu sumur warga di Kabupaten Kuansing perlu di cermati apalagi minyak mengalir secara kontinyu, untuk memastikan apakah minyak ini berasal dari alam atau minyak yang berasal dari hasil pengolahan (refinery) maka perlu dilakukan penelitian laboratorium terhadap sample minyak tersebut. Berdasarkan hasil pengujian di laboratorium Analisa Fluida Reservoir Jurusan Teknik Perminyakan Universitas Islam Riau, karakteristik minyak tersebut jika berdasarkan nilai Spesific Gravity sebesar 0.82 gr/cc dan API sebesar 40.6 maka minyak tersebut masuk ke kategori minyak ringan (Ligh Oil), hal ini mungkin saja terjadi karena adanya perubahan temperature dan tekanan dari bawah permukaan menuju permukaan sehingga fraksi ringan muncul di permukaan dan fraksi berat tetap terjebak atau tertinggal di lapisan bawah permukaan.

Published: November 2017

Squeeze cementing adalah bagian dari pekerjaan ulang sumur yang bertujuan untuk memperbaiki kualitas bonding cement yang buruk. Kualitas bonding cement yang buruk dapat menyebabkan meningkatnya harga water cut akibat masuknya fluida yang tidak diinginkan ke dalam sumur seperti air dan gas . Terjadinya High Water Cut pada Sumur BA#147 hingga 99% diikuti penurunan oil rate hingga 8.97 bopd yang signifikan menjadi suatu permasalahan. Hal ini dikarenakan oleh masalah terbatasnya fasilitas pengolahan air dan pertimbangan efisiensi produksi. Sehingga perlu dilakukan evaluasi kualitas bonding cement dan squeeze cementing disekitar zona produktif sumur BA#147. Metode analisis kualitas bonding cement yang digunakan yaitu Ultra Sonic Imager Tool (USIT). USIT mampu menginterpretasikan kondisi cement, casing dan jenis material (liquid dan gas) yang terdapat dibelakang casing. Selanjutnya dilakukan design squeeze cementing untuk meningkatkan kualitas bonding cement yang buruk. Setelah dilakukan analisis berdasarkan hasil image impedance yang diinterpretasikan USIT, didapatkan hasil kualitas bonding cement yang buruk pada interval kedalaman 3300ft – 3380ft. Berdasarkan hasil interpretasi USIT tersebut dilakukan squeeze cementing untuk memperbaiki bonding cement. Dibutuhkan 8.55 slurry cement, 1.27 bbl additive dan maximum squeeze pressure 586 psi. Teknik penyemenan yang digunakan yaitu teknik penyemenan bradenhead (open ended). Kualitas cement setelah dilakukan squeeze cementing pada sumur BA#147 yaitu good bonding berdasarkan harga image impedance yang ditampilkan pada rekaman USIT kedua.
