Abstract
The present study includes the compositional analysis and pyrolysis products obtained from Desmodesmus sp. cultivated in anaerobic digested effluents (DADE) from 300°C to 800°C. Compared to Desmodesmus sp. cultivated in BG11 (DBG11), both species exhibited a hydrogen content of ca. 6%, ca. 7% of nitrogen, and ca. 0.56% of sulfur except carbon content, of which was lower than DBG11. Pyrolysis products of DADE consisted of aliphatic hydrocarbons, aromatic hydrocarbons, acids, nitrogen compounds, phenols, polycyclic aromatic hydrocarbons (PAHs), alcohols, aldehydes, and furans. Pyrolysis of DADE at 800°C produced 62.52% (the maximum yield) of pyrolysis products compared to 41.89% at 600°C. Considering the reasonably high yield and minimum release of pollutants, lower temperature (600°C) was found to be optimum for producing biofuel from DADE. A process combing anaerobic digestion and algae cultivation can be proposed as a direct and effective way to produce biofuel so as to reduce contaminations to the environment.
Analogs of the Green and Puig correspondences for twisted group algebras
Authors: Harris Morton E. 
Published: October 2015

Abstract
In the modular representation theory of finite groups, we show that
the standard derivation of the Green
correspondence lifts to a derivation
of a Green correspondence for twisted
group algebras (Theorem 1.3). Then, from these results
we derive a lift of the Puig correspondences
for twisted group algebras (Theorem 1.6).

Clearly twisted group algebras arise
naturally in finite group modular representation theory. We conclude
with some suggestions for applications
in this mathematical area.

Brown Field Optimization: Coiled-Tubing Operations Beyond the Short String
Authors: Asedegbega Daniel , Desalu Adedeji , Hutapea Tumpal 
Published: October 2015

Abstract
Workover activities on wells have been traditionally carried out either to correct completion faults or to allow greater, more efficient access to perforations. While the former may not be geared toward reserve optimization, the latter objective is solely a drive towards optimization and enhancement of reserves.
With about half of the completions in Nigeria being dual string, there is the need to optimize production from two zones. However, despite reservoir depletion trends being similar in both the long and short string of a dual-completion system, fewer treatments are made through the short string in contrast to treatments deployed through the longer string. As a consequence, the true potential of a well may never be realized unless a total retrieval and recompletion workover is carried out with high-cost implications to the operators.
Performing workovers beyond the short string of dual completions is perceived as near impossible by most operating companies. The genuine skepticism is generated by the fact that e-line and slickline activity are limited to the end of tubing (EOT) only. This limitation is due to a high probability of becoming stuck or entangled with the long string. Due to this possibility, other workover options, specifically, coiled tubing (CT) beyond the short string, have also been perceived the same way.
Short-string intervention is geared toward performing rig-less intervention in the short string of a dual-completion system to optimize production from the upper zone. Our study evaluates different factors ranging from completion ratios and buckling tendencies to weight trends. Conclusions are drawn based on the evaluated data as to the feasibility or impracticability of a given intervention scenario.
In other words, the results of this study we believe provides a lifeline for the operators' existing short string by performing the same traditional treatment as occurs in long-string scenarios. We evaluate the client's skepticism of CT operations beyond the short string and draw a line between feasible and impractical operations by examining the various factors that affect interventions. The study also highlights that within reasonable limits, some of the perceived limitations are actually not limitations but hot spots to watch for during the design phase.
One success story is evaluated to support our study.

Introduction
Intervention operations performed with coiled tubing are usually restricted to the long string. The short string, though a potential candidate for intervention, is usually left to deplete gradually until it is shut-in or abandoned pending a major workover. This opinion is a result of the transferred mind-set of a slickline image on the coiled tubing. Slickline is prone to becoming entangled with the long string if it is run adjacent to it in the casing. This is one of the underlying reasons why the end of tubing in the short string is capped off and perforated.
Diagnosis of Production Performance After Multistage Fracture Stimulation in Horizontal Wells by Downhole Temperature Measurements
Authors: Cui Jingyuan , Zhu D.. , Jin Minquan 
Published: October 2015

Summary
Downhole temperature data that are measured by production logging tools (PLTs) or fiber-optic distributed-temperature sensors are used frequently today to diagnose multistage fracture treatments in horizontal or highly deviated wells. These temperature data, measured at the wellbore during fracturing and post-fracture, provide important transient-flow information that helps engineers understand the process of fracturing and the performance of fractured wells, to optimize fracture design.
The interpretation models developed to translate temperature data to flow conditions can be fully numerical simulations or analytical/semianalytical approaches. With reasonable assumptions, analytical/semianalytical models are more suitable for real-time field applications. This paper presents the application of a coupled semianalytical fracture model and a wellbore model to predict temperature and pressure behavior in multiple-fracture horizontal wells during production. The thermal model calculated the heat transfer in the fracture/reservoir/wellbore system, considering subtle temperature changes caused by the Joule-Thomson cooling effects. The results showed that transient temperature behavior is sensitive enough to estimate the fracture-initiation points, the number of created fractures, and the flow profile along the wellbore.
We discuss the characteristics of transient temperature behaviors and flow-rate distribution along a fractured horizontal wellbore. The temperature decreases when the gas entering the wellbore is strong at the toe and weak toward the heel and when the fractures are more evenly created along the wellbore because of the fluid mixture inside the wellbore. Two field cases are presented to illustrate the application of the temperature model to understand the fracture/flow distribution. The estimation of flow-rate distribution from the temperature model is compared with the interpretation of flow by PLTs. Although this is a single-phase gas model, we can identify the water sump at certain locations by identifying fast temperature recovery to geothermal value. Flow distribution from the temperature model presents a consistent trend with PLT measurement. It is more sensitive to the fluid entries (fracture locations) and less sensitive to the influence of the flow pattern inside the wellbore when compared with PLTs.
This work shows that temperature data can identify fracture locations (fluid-entry points) and estimate flow-rate distribution. Because of the complexity of flow in a multistage, fractured horizontal well, any measurement alone would not be able to provide clear description of the created fracture system. A combination of temperature data with other diagnostic methods will provide a better description of the production performance of such a well.
Oil Recovery From Gas-Over-Bitumen Reservoirs: Results From the AIDROH Pilot Project in Alberta
Authors: Hogue Bill , Gutiérrez Dubert , Hong Claire , Steiner Jennifer , Freeman Larry 
Published: October 2015

Summary
Producing from bitumen reservoirs overlain by gas caps can be a challenging task. The gas cap acts as a thief zone to the injected steam used during oil-recovery operations and hinders the effectiveness of processes such as steam-assisted gravity drainage (SAGD). Moreover, gas production from the gas cap can accentuate the problem even more by further depressurization of the gas zone.
Following a September 2003 ruling by the Alberta Energy Regulator (AER), the oil and gas industry in the province of Alberta, Canada, had approximately 130 million scf/D of sweet gas shut-in to maintain pressure in gas zones in communication with bitumen reservoirs. This decision led to the development of EnCAID (Cenovus' air-injection and -displacement process), a process in which air is injected into a gas-over-bitumen (GOB) zone, and combustion gases are used to displace the remaining formation gas while maintaining the required formation pressure.
An EnCAID pilot was started in June 2006, and preliminary results were reported in 2008. After 8 years of operations, the EnCAID project has not only proved to be effective at recovering natural gas and maintaining reservoir pressure, it has also shown it can heat up the bitumen zone and make the oil more mobile and amenable for production. This led to the development of the air-injection and -displacement for recovery with oil horizontal (AIDROH) process.
The AIDROH process is the second of two distinct stages. First, an air-injection well is drilled and perforated in the gas cap. The well is ignited and air injection is performed to sustain in-situ combustion in the gas zone. This phase is characterized by a radially expanding combustion front, accompanied by conduction heating into the bitumen below. The second stage begins when horizontal wells are drilled in the bitumen zone. The pressure sink caused by drawing down the wells alters the dynamics of the process and creates a pressure drive for the combustion front to push toward the producers in a top-down fashion, taking advantage of the combustion-front displacement and gravity drainage.
In light of the temperature increases observed in the bitumen overlain by the EnCAID project, a horizontal production well was drilled in late 2011 and commenced producing in early 2012. This paper provides an update of the EnCAID pilot results and presents a summary of the technical aspects of the AIDROH project, pilot results, and interpretation of the data gathered to date, such as observation-well temperatures, pre- and post-burn cores, and temperatures along the horizontal producer.
Results indicate that the AIDROH process has the potential to maximize oil production from GOB reservoirs, and efforts continue to be made to optimize its design and operation.

ABSTRACT
The presence of an impacted mandibular canine is one of the most difficult challenges that an orthodontist will meet. Orthodontic treatment is planned on an individual basis after thoroughly considering the patient’s overall facial and dentoskeletal characteristics; the duration, risks, and costs of treatment; patient preferences; and the orthodontist’s experience. This article reports an orthodontic treatment of a boy, age 12.9 years, with an impacted mandibular canine in the permanent dentition that was successfully managed. Radiographic analysis indicated a transmigration of the mandibular right canine. The orthodontic treatment plan included extraction of the deciduous right canine followed by surgical exposure and ligation of the permanent canine. Eruption was properly guided, and the correct position of the tooth was achieved. This challenging treatment approach is described in detail, including the mechanics used to align the impacted canine.
Test of Precipitation, Compensation and Monday Effect Hypotheses on Group Hare Trapping Effort

Published: October 2015

Live trapping in combination with translocation of wild animals is an important tool in wildlife management, but drivers of human trapping activity are poorly understood. Here we test three hypotheses that have been proposed to describe and explain temporal variation in group hunting‐trapping effort. Namely, we test the precipitation effect, effort compensation and Monday effect hypotheses on live trapping effort of brown hares for restocking. Analysis of 26 047 hares trapped in 460 trapping days during the period 1966–1995 in western Poland showed that seasonal onset of trapping was later during rainy autumns supporting avoidance of rainy weather by the trapping group. The hunting group increased the number of animals caught the day following a day with low off‐take providing evidence for the ability to respond quickly and compensate for short term variation in the trapping effort. Group trapping effort as reflected by number of hares caught was lower on Monday than on any other working day. This is in line with observations on weekly variation in working effort of employees across various contexts. We conclude that even seemingly standardized and rigid trapping schemes may be responsive to factors such as weather, experienced effort and subtle seasonal effects.
