Technology Today Series articles are general, descriptive representations that summarize the state of the art in an area of technology by describing recent developments for readers who are not specialists in the topics discussed. Written by individuals recognized as experts in the area, these articles provide key references to more definitive work and present specific details only to illustrate the technology. Purpose: to inform the general readership of recent advances in various areas of petroleum engineering.
Sand production is an important well-completion issue affecting well economics and, possibly, casing stability. This study compares predictions of sanding and casing deformation for a well in the U.S. Gulf of Mexico (GOM) shelf prepared before completion of the well with the results of a post-sanding event for this well. The sanding event was predicted adequately considering the uncertainty of the data entered into the model. The casing deformation monitored by the post-sanding survey also was consistent with the prediction of helical buckling caused by depletion of fluids only when cavities of vertical extent greater than 7 ft exist (e.g., because of sand production) around the wellbore. This study supports the use of these predictive methods in well-completion design.

Introduction
The driver for this study is a concern that sand production from GOM wells in weak sands may lead to casing failure. In Ekofisk, for example, casing failures caused by compaction have been studied, but these failures were not caused by solids production. There have been surprisingly few papers written about casing failures correlated with sand production. One is the Canadian heavy-oil-sands work, although it addresses massive amounts of sand produced (thousands of barrels). For this paper, we found an opportunity to assemble different aspects that had been studied separately into a more complete technical analysis. The subject has gained importance recently because of a renewed interest in managing sand production from wells rather than installing costly gravel packs.
Oil and/or gas production in weakly consolidated sandstone formations can lead to sand production when the reservoir pressure is depleted to the point at which the effective stress on the near-wellbore region exceeds the formation disaggregation strength. Sand production can lead to costly wellbore-cleanup operations, erosion damage to tubing and surface equipment, and significant sand-handling expenses. Thus, the prediction of sanding is an important design consideration when deciding whether a well should be completed with sand-control measures.
This Technology Today Series paper is based on paper 78236 prepared for the 2002 SPE/ISRM Rock Mechanics Conference.

Authors: Pourmohammad Alireza , Shekari Fariborz , Soltaniband Veeda 
Published: June 2014

Abstract
An experiment was concluded to evaluate the effects of priming on germination characteristics and establishment of rapeseed seedlings during three stages. In the first and second stages of experiment, the effects at three factors vis: cultivars (RVS, Hayola), waterdeficit stress (Control,-6 and -12 bar) and cycocel treatment (dry seeds, 300, 600, 900, 1200 and 1500 μM) on germination and seedling growth of plant were assayed. The results showed that priming had positive effects on germination percentage, germination rate index, germination index, and radicle length under water-deficit conditions. RVS had greater efficiency than other cultivars. The third section of experiment revealed that the priming of RVS seeds improved the stem, root and dry weight, total dry weight as well as leaf number and area of seedlings.

Geography of the Body: Jean Epstein’s Poetics and Conceptualization of the Body in his Unpublished Writings
Authors: Fernández Daniel Pitarch 
Published: June 2014

Abstract
Jean Epstein wrote many books during his life, but some of them were left unpublished. This unpublished corpus is of significant importance to understand his work and thinking. In this essay I address three of these books: Ganymède (a book on male homosexual ethics), Contre-pensées (Counter-Thoughts), a compilation of short essays on a wide variety of topics), and L’autre ciel (The Other Heaven), a literary work. My main purpose is to better understand a major motif in Epstein’s thought: the human body. These writings show how his interest in physiology was profound and very important during his whole life, and how he always emphasized the material side of any psychology, identity, or thought. Secondly, they address the topic of artificiality and humanity. Epstein claims that what is specifically human is to evolve through specialization and reification, even if it were against nature. And thirdly, they fully disclose the inherent sensuality of some Epstein texts (for instance his descriptions of close ups); one of the major subjects of L’autre ciel is male homoeroticism. These unpublished writings shed new light on Epstein’s film writings and must be considered in order to do a complete account of his work and thought.
Finding suitable paths for the elliptic curve primality proving algorithm
Authors: Járai Antal , Kiss Gyöngyvér 
Published: June 2014

Abstract
An important part of the Elliptic Curve Primality Proving algorithm consists of finding a sequence of elliptic curves with appropriate properties. In this paper we consider a strategy to search for an improved sequence, as part of an implementation (implemented in Magma 2.19) to obtain improved heuristics and compare it to an implementation which does not use such heuristics, namely to a built-in Magma function.

Damage in Concrete and its Detection by Use of Stress-Volumetric Strain Diagram
Authors: Jerga Ján , Krajči Ľudovít 
Published: June 2014

Abstract
The reliable determination of the damage degree of concrete in the structure is difficult and not seldom short-term compressive strengths are considered as real strengths of concrete. Because the load history of the construction is generally unknown, we do not know, whether there have been reached values in the vicinity of the peak of the stress-strain diagram. The strength at the sustained or repeated loading would be then significantly lower, as obtained from tests performed on intact samples. The diagnostic of concrete damage is impeded by environmental effects, resulting in the anisotropy of the development of micro cracks. The possibility is pointed out to use the characteristics of the stress volumetric strain diagram for the assessment of the condition of the material, with the perspective of the application for the determination of the residual long-term strength of concrete
Particulate Matter Assessment in the Air Based on the Heavy Metals Presence
Authors: Jandačka Dušan , Ďurčanská Daniela 
Published: June 2014

Abstract
Particulate matters are the result of various processes in the atmosphere that are part of everyday life. The chemical composition of these particles is mainly influenced by their origin. Their behavior is also dependent on meteorological conditions and other factors as well. The aim of this paper was to identify sources of particulate matters by means of statistical methods due to the presence of 17 heavy metals. The problem solving assumes the knowledge of multivariate statistical data analysis methods as principal components analysis (PCA), factor analysis (FA) and multivariate regression and vector algebra. For the application of methodology suitable software may prove appropriate.

The Influence of Tobacco Moisture Content on the Composition of Mainstream Smoke Yield as well as on the Temperature in the Combustion Zone / Einfluss des Feuchtigkeitsgehaltes von Cigaretten auf die Zusammensetzung des Rauches und die Glutzonentemperatur
Authors: Neurath G. , Horstmann H. 
Published: June 2014

Abstract
The authors studied the influence of tobacco moisture content on yield and composition of total particulate matter as well as on the temperature in the combustion zone of plain cigarettes. Total particulate matter and single components of the smoke can best be correlated with the dry weight of tobacco burnt in the mainstream. These figures are estimated by semi quantitative measures. The yield of dry total particulate matter is independent of tobacco moisture content if calculated on the basis mentioned above. The nicotine content of the smoke decreases with increasing moisture content of tobacco. Calculations on the where about of total nicotine suggest that nicotine is increasingly decomposed in the presence of moisture. The yield of 1,2- and 3,4-benzopyrene rises with increasing moisture content but with different slopes. The temperature of the combustion zone is independent of tobacco moisture content. The chemical and catalytic importance of moisture in smoking processes is mentioned.

Species richness and dominance structure of bee communities in the 2 regions are compared, and species responsible for significant differences are identified.
The Antioxidant Activity of Maltese Honey
Authors: Meinen Natacha , Camilleri Liberato , Attard Everaldo 
Published: June 2014

Abstract
Maltese honey has been valued for its medicinal properties since ancient times, so much so that the word Malta is derived from the ancient Greek word, Melite, which means honey. In this study, Maltese honey samples (n = 30) from three harvest seasons and different floral sources were analysed to determine their antioxidant/antiradical properties. Colorimetric assays were used to determine the polyphenol content, flavonoid content, and colour intensity, and these values were analysed to determine whether they correlated with radical scavenging activity as determined by bioassays. The honey samples varied in their DPPH activity (range, 3.326 - 11.865 mg AEAC/100 g honey), reducing power (EC 50 range: 5.632 - 14.453 mg/ml), total phenolic content (range, 8.114 - 109.765 mg TAE/100 g honey), total flavonoids (range, 0.655 - 212.865 mg RE/100 g honey), and colour intensity (range, 0.000 - 99.581 mm Pfund). The data were subjected to factor analysis using principal components. The antioxidant properties correlated significantly with total polyphenol content and colour (p<0.0001). Principal components analysis revealed three clusters of honey corresponding to the three harvest seasons.

Published: June 2014

Abstract
The aim of this study was to develop an effective method of overwintering reserve honey bee queens in two-storey mini-plus mating nuclei and in 3-comb nuclei (frames 36 x 26 cm, Wielkopolski hive). The assay was performed during three wintering seasons (2005 - 2008) parallel at two centers in Poland: the Division of Apiculture at the University of Life Sciences (SGGW) in Warsaw, and the Apiculture Division at the University of Warmia and Mazury (UWM) in Olsztyn. The results showed that 59% of queens overwintered in mini-plus nuclei and 77% in 3-comb nuclei. Among queens in mini-plus nuclei 63% overwintered in bee yard and only 55% in cellar. Within queens in 3-comb nuclei, 62% overwintered in Olsztyn and 91% in Warsaw. The highest survival rate of 93% was observed in Warsaw during the first season. Due to low survival rate, it is not recommended to overwinter the queens in miniplus nuclei.
The Effect of Open Brood and Colony Strength on the Onset of Oviposition by Queen Bees
Authors: Gąbka Jakub , Woyke Jerzy 
Published: June 2014

Abstract
In bee colonies without open brood, e.g., after swarming, there is no need for royal jelly, and nurse bees thus do not produce it. According to many beekeepers, adding combs with open brood restarts the production of royal jelly by nurse bees, and the virgin queens then are better fed and start earlier oviposition. The purpose of this study was to investigate whether the presence of open brood and the strength of the colonies affect the onset of oviposition by queen bees. Open brood in colonies with virgins before and during mating flights did not accelerate the initiation of oviposition by the queens. In addition, no differences were identified in starting oviposition by queens in strong colonies of more than 30,000 worker bees, or in weak colonies with up to 1,000 workers. Overall, the results showed that neither open brood in the nests, nor the strength of the colonies affects the onset of oviposition by queen bees.
Morphological Discrimination of Greek Honey Bee Populations Based on Geometric Morphometrics Analysis of Wing Shape
Authors: Charistos Leonidas , Hatjina Fani , Bouga Maria , Mladenovic Mica , Maistros Anastasios D. 
Published: June 2014

Abstract
Honey bees collected from 32 different localities in Greece were studied based on the geometric morphometrics approach using the coordinates of 19 landmarks located at wing vein intersections. Procrustes analysis, principal component analysis, and Canonical variate analysis (CVA) detected population variability among the studied samples. According to the Principal component analysis (PCA ) of pooled data from each locality, the most differentiated populations were the populations from the Aegean island localities Astypalaia, Chios, and Kythira. However, the populations with the most distant according to the canonical variate analysis performed on all measurements were the populations from Heraklion and Chania (both from Crete island). These results can be used as a starting point for the use of geometric morphometrics in the discrimination of honey bee populations in Greece and the establishment of conservation areas for local honey bee populations.

Published: June 2014

Abstract
This study, conducted in 2008 and 2012 - 2013, evaluated the flowering pattern (seasonal and diurnal), the abundance of flowering, nectar, and pollen yield, and insect visitor activity for Corydalis solida (L.) Clairv. and C. cava Schweig. et Koerte. The populations occur in the ground layer of a deciduous forest (Fagetalia ordo, Querco-Fagetea class) in a natural gorge within the current area of the UMCS Botanical Garden in Lublin, Poland (51° 16’ N, 22° 30’ E). The phenology of Corydalis species showed distinct year-to-year plasticity (e.g., blooming period in March - April or in April - May; duration 18 - 42 days). The most intensive flower opening was noted in the early morning hours (85 - 90% of daily openings occurred between 6.00 and 10.00 h, GMT +2 h). The average sugar yield was similar at 4.6 kg/ha (C. cava) and 5.2 kg/ha (C. solida), but the average pollen production differed and reached 2.1 kg/ha (C. cava) and 4.1 kg/ha (C. solida). The flower-visitor interaction in Corydalis species involved both biological (early pattern of diurnal flowering, protandry, pollen presentation at the moment of anthesis) and morphological (nectar hidden in deep spur) features. Apis mellifera foragers predominated on both Corydalis species (mean of total visitors, 68.0% to C. solida; 62.5% to C. cava) and foraged mainly for pollen (82% of foragers), while bumblebee queens (mean of total visitors, 32.0% to C. solida; 37.5% to C. cava) collected mainly nectar (68.0% of foragers).
The Effects of Age of Grafted Larvae and of Supplemental Feeding on Performance of Iranian Honey Bee Colonies (Apis Mellifera Meda)

Published: June 2014

Abstract
The performance of bee colonies greatly depends on the quality of the queens. The current research was conducted at the apiary of the Faculty of Agriculture, Zanjan University, in Zanjan, Iran. Together, 24 rearing colonies were assigned to 4 grafting larvae age groups: 1-day-old, 2-day-old, 3-day-old, and emergency queens. Two feeding groups, fed and not fed, were created. The effects of reared queens on biological characteristics and performance of honeybee colonies (Apis mellifera meda) headed by those queens were measured. Age of grafted larvae significantly influenced the results. The performance ratios of the most efficient colonies headed by queens reared from 1-day-old larvae compared with the least-efficient queens reared from 3-day-old larvae were 118% in brood production, 140% in bee population, and 154% in honey production. However, the age of grafted larvae did not affect colony defense behavior. Supplemental feeding of rearing colonies increased brood production to 111%, bee population to 116%, and honey production to 115%. A combination of the effect of age of larvae and supplemental feeding resulted in twice as much honey (12 kg) produced by colonies with queens reared from 1-day-old larvae in fed rearing colonies compared to those with queens raised from 3-day-old larvae in unfed rearing colonies.
Susceptibility of Bee Larvae to Chalkbrood in Relation to Hygienic Behaviour of Worker Bees in Colonies of Chosen Races of Honeybee (Apis Mellifera )
Authors: Panasiuk Beata , Bieńkowska Małgorzata , Gerula Dariusz , Węgrzynowicz Paweł 
Published: June 2014

Abstract
The susceptibility of bee larvae to Ascosphaera apis infestation and the hygienic behaviour of worker bees in relation to A. apis infected and freeze-killed brood were evaluated in three races of bees: Apis mellifera carnica, Apis mellifera caucasica, and Apis mellifera mellifera. Experimental bee colonies were evaluated in field conditions during the three beekeeping seasons. The lowest percentage of infected larvae was observed in car GR1 and mel A colonies (8.5% and 15%, respectively) and the highest in car Mr and cau P colonies (21% and 24.3%, respectively). Bees in the car GR1 and mel A colonies removed mummified brood in a shorter period of time (6.5 and 7.1 days on average, respectively) than car Mr and cau P colonies (above 8 days). Bees in the mel A and car GR1 colonies cleaned significantly more cells with freeze-killed brood within 24 and 48 hours (above 70% and 80% on average, respectively) than car Mr and cau P colonies (on average 10 - 20% lower cleaning rate). A low correlation coefficient was found for the susceptibility of larvae to A. apis infection and hygienic behaviour.
