Personal and social predictors of risky sexual behaviours in Iranian youth
Authors: Mikaeli Manee Farzaneh , Aria Alireza Mohammadi 
Published: June 2018

This study investigates the power of psychological variables of depression, self-esteem and impulsivity as well as social variables of perceived social support and subjective socio-economic status in predicting risky sexual behaviours. To accomplish this study, all those individuals who were commuting to the Behavioural Diseases Counseling Center of Urmia over the last 6 years were considered and then, 80 individuals were selected as the research sample using available sampling method. The Rosenberg Self-esteem Scale, researcher-made scale for assessing risky sexual behaviours, Beck depression inventory, Barratt impulsivity scale, Zimet perceived social support scale and researcher-made questionnaire of subjective social status were used in this study. The results showed that all the variables have had significant roles in predicting the risky sexual behaviours. Depression has had the most power to predict risky sexual behaviours. After that self-esteem, perceived social support and subjective social status could predict important parts of variances in the risky behaviours (R2 = 0.57). Regarding the mentioned results, it may be concluded that psychological factors to commit risky sexual behaviours. Thus, personal factors-based preventive and therapeutic programmes for sexual risky behaviours for youth are recommended.

Transient Coupling of Swab/Surge Pressure and In-Situ Stress for Wellbore-Stability Evaluation During Tripping
Authors: Zhang Feifei , Kang Yongfeng , Wang Zhaoyang , Miska Stefan , Yu Mengjiao , Zamanipour Zahra 
Published: June 2018

Summary
This paper identifies wellbore-stability concerns caused by transient swab/surge pressures during deepwater-drilling tripping and reaming operations. Wellbore-stability analysis that couples transient swab/surge wellbore-pressure oscillations and in-situ-stress field oscillations in the near-wellbore (NWB) zone in deepwater drilling is presented.
A transient swab/surge model is developed by considering drillstring components, wellbore structure, formation elasticity, pipe elasticity, fluid compressibility, fluid rheology, and the flow between wellbore and formation. Real-time pressure oscillations during tripping/reaming are obtained. On the basis of geomechanical principles, in-situ stress around the wellbore is calculated by coupling transient wellbore pressure with swab/surge pressure, pore pressure, and original formation-stress status to perform wellbore-stability analysis.
By applying the breakout failure and wellbore-fracture failure in the analysis, a work flow is proposed to obtain the safe-operating window for tripping and reaming processes. On the basis of this study, it is determined that the safe drilling-operation window for wellbore stability consists of more than just fluid density. The oscillation magnitude of transient wellbore pressure can be larger than the frictional pressure loss during the normal-circulation process. With the effect of swab/surge pressure, the safe-operating window can become narrower than expected. The induced pore pressure decreases monotonically as the radial distance increases, and it is limited only to the NWB region and dissipates within one to two hole diameters away from the wellbore.
This study provides insight into the integration of wellbore-stability analysis and transient swab/surge-pressure analysis, which is discussed rarely in the literature. It indicates that tripping-induced transient-stress and pore-pressure changes can place important impacts on the effective-stress clouds for the NWB region, which affect the wellbore-stability status significantly.
Proppant-Conductivity Testing Under Simulated Reservoir Conditions: Impact of Crushing, Embedment, and Diagenesis on Long-Term Production in Shales
Authors: Mittal Abhinav , Rai Chandra S. , Sondergeld Carl H. 
Published: June 2018

Summary
Hydraulic fractures act as conduits connecting a wellbore to nanodarcy-permeability unconventional reservoirs. Proppants are responsible for enhancing the fracture conductivity, and they help in maintaining high production rates. This study is focused on the measurement of long-term conductivity of proppant packs at simulated reservoir-temperature and pressure conditions. Various conductivity-impairment mechanisms such as proppant crushing, fines migration, embedment, and diagenesis are investigated.
Testing was performed with a conductivity cell that allows simultaneous measurement of fracture compaction and permeability. The proppant-pack performance during compression between metal and shale platens was compared. The proppant-filled fracture (concentration of 0.75–3 lbm/ft2) is subjected to axial load (5,000 psi) to simulate closure stress. Brine (3% NaCl + 0.5% KCl) is flowed through the pack at a constant rate (3 cm3/min) at 250°F during an extended duration of time (10–60 days). In this study, Ottawa sand proppant was used between platen facies fabricated from Vaca Muerta and Eagle Ford shales.
Testing between metal platens indicated that the reduction in permeability with 20/40-mesh Ottawa sand (≈30% during 12 days) was less than that of 60/100-mesh Ottawa sand, which suffered a 99% reduction in only 4 days.
Measurements with 20/40-mesh Ottawa sand between shale platens were conducted at 1.5 lbm/ft2. During a duration of 10 days, the Eagle Ford platens proppant pack exhibits a greater reduction in permeability, in comparison with Vaca Muerta platens. The normalized compaction for Eagle Ford shale platens is 20% more than Vaca Muerta platens because of greater proppant embedment. Particle-size analysis and scanning-electron-microscopy (SEM) images verify proppant crushing, fines migration, and embedment as dominant damage mechanisms. These factors are observed to depend on the testing of shales. The results suggest a substantial degradation of permeability during the initial 5 days of testing, after which the permeability appears to stabilize. Crushed proppant and dislodged shale-surface particles contribute to the fines generated; a greater concentration of fines is observed downstream.
In a separate study between Vaca Muerta platens, under similar closure stress and temperature conditions at 2-lbm/ft2 proppant concentration, the permeability reduced by almost three orders of magnitude during a duration of 60 days. It was also observed that growth of diagenetic smectite is accelerated by making the fluid more basic (pH of 10).

O feijão-fava (Phaseolus lunatus L.) é uma importante fonte de alimento para o Brasil principalmente para a região Nordeste. Devido à relevância dessa leguminosa, estudos em melhoramento genético se fazem necessários, sendo que informações sobre a viabilidade polínica constitui um dos fatores responsáveis pelo sucesso dos programas de melhoramento via hibridação. Com o intuito de fornecer informações a respeito dos acessos de feijão-fava provenientes do Banco Ativo de Germoplasma da Universidade Federal do Piauí (BAG-UFPI), objetivou-se estimar a viabilidade polínica de nove acessos, através de quatro métodos coloriméticos: carmim acético 2%, orceína acética 2%, fucsina e lugol. Foram coletados os botões florais na pré-antese e fixados em etanol:ácido acético (3:1) por 24 horas e, posteriormente, permaneceram em etanol 70% sob refrigeração até a preparação das lâminas pela técnica de esmagamento. Foi utilizado um delineamento inteiramente casualizado em esquema fatorial e os dados foram comparados pelo teste Scott-Knott ao nível de 5% de probabilidade de erro. Os quatro métodos colorimétricos foram eficientes em estimar a viabilidade entre os acessos, os quais apresentaram alta viabilidade polínica com valores acima de 70%, importante para viabilização dos trabalhos de melhoramento genético.

Abstract
Deterioration models can be successfully deployed only if decision-makers trust the modelling outcomes and are aware of model uncertainties. Our study aims to address this issue by developing a set of clearly understandable metrics to assess the performance of sewer deterioration models from an end-user perspective. The developed metrics are used to benchmark the performance of a statistical model, namely, GompitZ based on survival analysis and Markov-chains, and a machine learning model, namely, Random Forest, an ensemble learning method based on decision trees. The models have been trained with the extensive CCTV dataset of the sewer network of Berlin, Germany (115,258 inspections). At network level, both models give satisfactory outcomes with deviations between predicted and inspected condition distributions below 5%. At pipe level, the statistical model does not perform better than a simple random model, which attributes randomly a condition class to each inspected pipe, whereas the machine learning model provides satisfying performance. 66.7% of the pipes inspected in bad condition have been predicted correctly. The machine learning approach shows a strong potential for supporting operators in the identification of pipes in critical condition for inspection programs whereas the statistical approach is more adapted to support strategic rehabilitation planning.
Performance evaluation of a municipal water distribution system using WaterCAD and Epanet

Abstract
Population explosion in urban settings usually exerts enormous pressure on existing water supply systems. The result is that overall water demand is usually not satisfied. This study evaluated the performance of Wadata sub-zone water distribution system with respect to pressure, velocity, hydraulic head loss and nodal demands using WaterCAD and Epanet. There was no statistical difference between the results of Epanet and WaterCAD, however, Epanet produced slightly higher results of pressure and velocity in about 60% of all cases examined. About 19 percent (18.52%) of the total number of nodes analyzed had negative pressures while 69 percent (69%) of the nodes had pressures less than the adopted pressure for the analysis. These negative pressures indicate that there is inadequate head within the distribution network for water conveyance to all the sections. About 88 percent (87.7%) of flow velocities in the pipes were within the adopted velocity while around 12 percent (12.3%) of the velocities exceeded the adopted velocity. These excess velocities are partly responsible for the leakages and pipe bursts observed at some points within the system. The results in this study revealed that the performance of the water distribution system of Wadata sub-zone under current demand is inefficient.

Published: June 2018

Tiivistelmä
Perusopetuksen opetussuunnitelman perusteissa (POPS2014) mainitaan tavoitteeksi, että oppilaan kielitietoisuus vahvistuu, oppilas innostuisi tutkimaan kieltä ja sen variantteja ja että oppilas harjaantuisi käyttämään käsitteitä, joilla kielestä voidaan puhua. Kielitiedon opetuksesta on kuitenkin esitetty varsin vähän konkreettisia pedagogisia menetelmiä. Tämän opetuksenkehittämistutkimuksen tavoitteena on luokitella ja kehittää kielitiedon tehtäviä soveltaen Krathwohlin (2002) tavoitetaksonomia-ajattelua siten, että ensimmäisen tason tavoitteena on käsitteiden muistaminen, toisen tason käsitteiden ymmärtäminen ja käyttäminen suppeissa tehtävissä, kolmannen käsitteiden välisten suhteinen ymmärtäminen ja neljännen tason tavoitteena on käsitteiden soveltaminen tekstin analyysissä. Lisäksi mallissa sovelletaan kielentämistä pedagogisena menetelmänä. Esittelemämme tehtävätyypit voidaan luokitella tunnistamis-, tuottamis-, suhteuttamis- ja analyysitehtäviin sekä ilmiöön kohdistuviin tutkivan oppimisen tehtäviin.
