Authors: Omar Marwa , Agawani Waleed , Abdelhamid Atef , Al Ajmi AbdaAllah , Al Rushoud Abdulaziz , Al Ghareeb Majid
Published: February 2017

In the prolific North Kuwait field, the 16 inch intermediate vertical section is typically drilled with Tungesten Carbide Insert (TCI) drill bit [445 IADC] and rotary assembly. The TCI average Rate of Penetration (ROP), through approximately 4,800 feet of limestone, sandstone and shale, is 38.7 feet per hour. Given the operator's target to reduce drilling time and minimize the North Kuwait well cycles; the hybrid drill bit was proposed to raise ROP performance and save drilling days per well.

The main challenge was to significantly reduce drilling time and enhance the cost-per-foot of the application with the new hybrid drill bit. In addition to providing smooth torque fluctuations, similar to that of the roller cones drill bit.

A specialized Drilling Application Review Team (DART) from the service provider implemented an optimization process to achieve the aforementioned targets. The hybrid bit design has been revised and upgraded to best-fit the interbedded carbonates application. Bottom Hole Assembly has been modeled and optimized by the cross-functional engineering team and the client to ensure best torque response while drilling. Moreover, a detailed formation drilling analysis has been conducted to accurately anticipate hybrid bit ideal case.

The optimized hybrid drill bit set the highest ROP record, at 80 feet per hour in North Kuwait achieving 107 percent improvement from offsets’ average performance. Moreover, the optimized design delivered 2 and a half days savings when compared to field offsets by conventional technology. The selected system generated smooth torque response and hence high energy efficiency. This success has been repeated over multiple wells in North Kuwait project; proving consistency in technology value.

Published: February 2017

Nanotechnology is an emerging multidisciplinary technique that involves application based on the synthesis of molecules in nano-scale size range. Nanotechnology is also seen as new and fast emerging field that involves the manufacture, processing and application of structure, device and system by controlling shape and size in nanometer scale. The concept of nanotechnology is driven from the Greek word nano (meaning dwarf). The nano-particles are defined as a discrete entity that has dimensions of the order of 100 nm or less. It is the small size in combination with the chemical composition and surface structure that gives the nano-particles their unique features. The alterations in physical properties serve to enhance versatility and efficacy in product development, resulting in more effective industrial and medical applications. As a result of the widespread use of nanotechnology and nano-materials, these particles find their way into the environment. Therefore, a focus on the source of nano-particles in the environment and their effects is included. This review concentrate on the recent information about analytical developments to assess the occurrence, fate and behavior of nano-materials in environment. It also focuses on the applications of nanotechnology in environment, especially in the area of air and water purifications.

Risk management of a development of systems and territories is one of the key problems of managerial decision-making. This is due to the impossibility of carrying out model experiments and the complexity of formalization of characteristics. The necessity of considering the peculiarities of the spatial distribution of subjects and objects of management allows to speak about relevance of geoinformation management. Compared with other classes of potentially hazardous systems, spatially distributed systems and areas characterized by a significant level of inertia that contributes to sustainability in development, but hinders the development management and allows the dynamics to determine the influence of threat factors. The effects of hazards on the territory are systemic. The article describes: - analysis of dynamics of control conditions for the development of spatially distributed objects and territories; - classification of risks for coastal management; - principles of risk management development of the coastal areas; - the system model (conceptual model) of risk management in its spatial aspect, as well as private models for risk management under the influence of natural factors.

Background:

Pancreatic cancer (PC) is considered an incurable disease due to
late diagnosis, rapid spread and negligible response treatment methods, with a 5-year survival
rate of only 7%. Hence, there is an urgency in developing novel strategies for PC prevention.
This review is focused on discussing the challenges in understanding complex immune
functions in tumor microenvironment and host-induced immune responses against
tumors, selection of antigens for development of preventive vaccines, lessons from immunoprevention
clinical trials and challenges in developing future vaccines.

Methods:

65 original articles were referenced from various sources, based on immunoprevention
or criteria pertaining to tumor antigens and immune responses in PC. All these articles
were analyzed for the method details and results obtained, and the existing challenges
were derived for successful development of clinical immunoprevention strategies.

Results:

The analysis of these articles and our experience with preclinical efficacy evaluations
of various preventive approaches against PC helped in identifying specific tumor antigens
as targets which can overcome tumor cell immune suppression. This review discussed
the status of primary, secondary and tertiary preventive vaccines and reasons for failure of
therapeutic vaccines. The key parameters for effective vaccination were identified, including
stage of the disease for vaccination efficacy, use of appropriate animal models for development
of preventive vaccines. Potential of chemopreventive agents as adjuvants in immunoprevention
was discussed. This review identified new challenges for development of
immunopreventive vaccines.

Conclusion:

Fluorescent graphene quantum dots (GQDs) have attracted increasing interest
in cancer bioimaging due to their stable photoluminescence (PL), high stability, low cytotoxicity,
and good biocompatibility. In this review, we present the synthesis and chemical
modification of GQDs firstly, and then introduce their unique physical, chemical, and
biological properties like the absorption, PL, and cytotoxicity of GQDs. Finally and most
importantly, the recent applications of GQDs in cancer bioimaging are demonstrated in
detail, in which we focus on the biofunctionalization of GQDs for specific cancer cell imaging
and real-time molecular imaging in live cells. We expect this work would provide
valuable guides on the synthesis and modification of GQDs with adjustable properties for
various biomedical applications in the future.
Revised Level Set-Based Method for Topology Optimization and Its Applications in Bridge Construction
Authors: Wu Jing , Wu Li
Published: February 2017

To cure imperfections such as low accuracy and the lack of ability to nucleate hole in the conventional level set-based topology optimization method, a novel method using a trapezoidal method with discrete design variables is proposed. The proposed method can simultaneously accomplish topology and shape optimization. The finite element method is employed to obtain element properties and provide data for calculating design and topological sensitivities. With the aim of performing the finite element method on a non-conforming mesh, a relation between the level set function and the element densities field has to be clearly defined. The element densities field is obtained by averaging the Heaviside function values. The Lagrange multiplier method is exploited to fulfill the volume constraint. Based on topological and design sensitivity and the trapezoidal method, the Hamilton-Jacobi partial differential equation is updated recursively to find the optimal layout. In order to stabilize the iterations and improve the efficiency of the algorithm, re-initiation of the level set function is necessary. Then, the detailed process of a cantilever design is illustrated. To demonstrate the applications of the proposed method in bridge construction, two numerical examples of a pylon bridge design are introduced. It is shown that the results match practical designs very well, and the proposed method is a helpful tool in bridge design.

Published: February 2017

Eugenol is a compound with a variety of reactive functional groups such as allyl, hydroxy and methoxy. The presence of the functional groups brings eugenol possible to undertake the transformation into various derivative compounds with diverse activities. One of the simple and possible transformations is methylation or alkylation. Commonly, methyl halides and dimethyl sulphate are used as methylation agent. However, those kinds of methylation agents are toxic and carcinogenic. In this research dimethyl carbonate, an alternative methylation agent is used, because of its low toxicity, green, and economic. The synthesis has been carried out by using a catalyst. Bentonite was activated by heating to a temperature using 300 °C. Methylation was shown by the formation of a light yellow liquid (25.71% yield). The structures of products were characterized by GC-MS and obtained a compound, namely bis eugenol (4-allyl-2-methoxyphenoxy) methane (2.37% yield).

Authors: Pratiwi Wiwit Sri Werdi , Anal Anil Kumar , Putra Surya Rosa
Published: February 2017

Indonesia is one of the biggest central distributions of sago starch. There are some characteristics of sago starch which make it difficult to use in variation of foods. In this study, resistant starch type III (RS3) was produced from sago starch by using lintnerization-autoclaving (LA). Physicochemical characterizations of RS3 were compared by native sago starch (NA), hydrolyzed starch by distilled water (DW) and lintnerized starch (L). Amylose content decreased after hydrolyzed by DW and L, but increasing by using LA. Protein and fat contents decreased after hydrolysis, but crude fiber content increasing, the highest value was obtained lintnerized-autoclaved starch. Lintnerized-autoclaved starch has more compact and rigid structure. The RVA viscosity, swelling power and water holding capacity values reduced after all treatments. Oil in water emulsions were also analyzed by mixture of RS3 and emulsifier (casein or SPI). Viscosities of emulsions from RS casein were lower than those of RS-SPI. Emulsion capacity and emulsion stability values were better gotten using RS-SPI than RS-casein. The highest of emulsion capacity was obtained 11.33%. For storage period, the lowest peroxide and anisidine values of mixture RS-emulsifier were resulted from 5% emulsifier + 5% RS + 5% fish oil.

Global Coordination against Global Warning: “Catch-up” Countries against Affluent Countries
Authors: Lane Jan-Erik
Published: February 2017

The UNFCCC has delivered the COP21 project as the main response to climate change, promising radical decarbonisation of the country economies in the world. A promise is merely a verbal commitment ex ante, whereas the outcomes of policy-making and government coordination inform about the actual matters of fact ex post. Scholars now fear that there will be reneging or defection in the COP21 games to be started now with a long time frame into the next half of this century. Thus, world famous Stern (2016) asks what we are waiting for, given his stern warnings already in 2007. And Conca (2015) suggests that environmentalism and climate change becomes the chief task for the United Nations, on par with peace, security, human rights and development. Star economist Sachs (2015a, b, c) promotes the idea of linking anti-global warming policies with general Sustainable Development (SDGs), including anti-poverty policies. Yet, they bypass fundamentals: climate change is driven by Juggernaut forces, namely the links between GDP, energy consumption and greenhouse gases involving the economic struggle between the haves and have-nots. The challenges in implementing the COP21 goals (I+III) are formidable.

Published: February 2017

In this study, seven maize inbred lines representing different tropical,
drought tolerant populations and two adapted temperate maize inbred lines
were crossed in a half-diallel mating design to determine combining
abilities. The genotypes were tested in well-watered (WW) and managed water
stressed (WS) conditions in 2013 and 2014. General combining ability (GCA)
and specific combining ability (SCA) mean squares were significant for all
investigated traits and demonstrated both additive and non-additive genetic
effects in both conditions. Higher desired leaf rolling, leaf senescence,
stomatal conductance and leaf chlorophyll content GCA effects of tropical
inbreds under WS conditions showed the presence of the valuable allels
related to drought stress. SCA analysis revealed that the best hybrids for
water use efficiency and irrigation water use efficiency were tropical x
temperate crosses. Stress tolerance index and drought resistance index
identified G5 x G9, a tropical x temperate hybrid, as the most tolerant
hybrid to drought. Our study suggests that tropical drought tolerant
germplasm has the potential to contribute useful genetic diversity to
temperate maize breeding programs.

of Helicobacter pylori virulence factors (such as cagA). The HopQ is one of
the outer membrane proteins involved in bacterial adherence to gastric mucosa
and has been suggested to also play a role in the virulence of H. pylori.
This gene has been shown in two types. The purpose of the current study was
to investigate the association between different H. pylori virulence hopQ
alleles (types I and II) and patients with gastroduodenal disorders. For this
purpose 58 stomach biopsies the of patients with gastric cancer and 100
saliva samples from healthy individuals were collected. Then genomic DNA was
purified and PCR for was done for desired genes via specific primers. The H.
pylori infections were diagnosed by PCR for GlmM gene. Then frequencies of
hopQI+, hopQII+ and hopQI+ hopQII+ genotypes were determined in H. pylori
infected cases. Statistical analysis showed that there were not significant
differences between healthy and diseased ones for genotypes hopQI+, hopQII+
and hopQI+ hopQII+.

Two main aims of this investigation were to predict kernel ratio (KR) and
kernel weight (KW) from some walnut characteristics, respectively. For these
aims, a total of 112 Walnut genotypes growing in nature were collected at
Darende District of Malatya province in the Eastern Anatolia region of
Turkiye. The walnut characteristics evaluated were nut length (NL), nut width
(NW), nut height (NH), nut weight (NWe), shell thickness (ST), kernel ratio
(KR) and kernel weight (KW), respectively. Independent variables were
subjected to factor analysis based on principal component extraction method
and VARIMAX rotation. On the basis of jointly using factor scores in multiple
regression, KR (81.3 % R2 and 80.6 % adjusted R2) and KW (94.7% R2 and 94.5%
adjusted R2) characteristics were predicted by using four factor scores with
a big accuracy without multicollinearity problem. Consequently, the present
results revealed that, walnuts of heavier KW and NWe in the prediction of KR
would be expected to produce those of higher KR, and walnuts of higher values
in NH, NW, NWe, ST, NL, and KR in the prediction of KW would be expected to
produce those of heavier KW. The knowledge may help walnut breeders to
improve new selection strategies.

Finding of fetal chromosomal mosaicism complicates genetic counseling, as
well as pregnancy management. The aim of this study was to determine the risk
of confined placental mosaicism in short term culture of chorionic villous
samples. We conducted a retrospective review of karyotype analysis results
obtained after chorionic villous sampling (CVS) in two years period. A 420
samples of chorionic villi were taken transabdominally and obtained by a
semidirect method (overnight incubating culture). All fetuses with CVS
mosaicism were under the intensive perinatal care. In all cases of chromosome
mosaicism the additional karyotyping was performed from fetal blood samples
after 22nd gestational week in order to exclude true fetal mosaicism. After
delivery newborns were examined by experienced pediatrician. From 420
analyzed samples in 11 (2,6%) cases we found placental mosaicism. No
anomalies were seen in genetic sonogram of this fetuses and mosaicism was
confirmed only in one case. Confined placental mosaicism (CPM) was found in
2,1% (9/420) of all analyzed cases, and it made 90% of all placental
mosaicism. In 60% (6/10) of placental mosaicism cases we found mosaicism with
single aberrant cell. Trisomy 21 mosaicism was the most frequent aberration
found in 30% of cases. Finding of mosaicism in chorionic villi sample is at
special importance for genetic counseling, because every case has to be
reveled individually regarding the type and level of mosaicism. Anyway, in
every case of placental mosaicism intensive antenatal monitoring is
necessary, with additional chromosome analysis from different tissue in
consideration of previous findings.

Sunflower (Helianthus annuus L.) has high needs for water but can tolerate
drought very well because, under stress conditions, its well developed root
system can supply water and mineral nutrients from deeper soil layers.
Reduced water content in soil affects plant growth and development,
photosynthetic rate and causes rapid leaf senescence. In this study, we
measured maximum quantum yield of photosystem II (Fv/Fm), photosynthetic
performance index (PIABS) and leaf temperature (LT) on 13 sunflower
genotypes at different soil water contents. By calculating stress tolerance
indices (STI) of Fv/Fm and PIABS parameters we evaluated drought tolerance
for every tested sunflower genotype at given soil water contents. The
experiment was set up in vegetation pots in two treatments with different
soil water contents (60% and 80% of field water capacity) in three
replications. Based on the obtained results for Fv/Fm and PIABS and STI
values of Fv/Fm and PIABS parameters, we concluded that genotypes 5 and 12
had higher tolerance at both treatments, as opposed to genotypes 2 and 13
which were less tolerant. These analyses will help breeders to select
genotypes adapted to different farming areas which is, along with the use of
recommended production practices, the background for profitable sunflower
production.
