Published: November 2018

Ekosistem mangrove memiliki kemampuan untuk menyerap dan menyimpan karbon. Beberapa penelitian memperlihatkan besarnya kemampuan penyerapan dan penyimpanan karbon oleh ekosistem ini. Namun demikian, kapasitas penyimpanan ini akan menurun karena deforestrasi dan konversi lahan. Tujuan penelitian ini adalah menganalisa dampak alih fungsi lahan mangrove terhadap sifat sedimen serta kemampuannya dalam menyimpan karbon. Penelitian dilakukan di empat lokasi yaitu di Kabupaten Berau - Kalimantan Timur dan Karimunjawa-Jawa Tengah yang mewakili daerah alami serta, Kabupaten Pati - Jawa Tengah dan Kabupaten Indramayu – Jawa Barat yang mewakili mangrove yang pernah mengalami alih fungsi lahan dan telah direhabilitasi. Sedimen diambil minimal sampai pada kedalaman satu meter dengan menggunakan soil auger. Sebanyak empat sampel diambil pada setiap core sediment pada interval kedalaman 0-15, 15-30, 30-50 dan 50-100 cm. Mangrove yang pernah mengalami alih fungsi lahan memiliki nilai bulk density yang lebih tinggi serta konsentrasi CN (%) dan simpanan karbon (MgCha-1) yang lebih rendah dibandingkan dengan lokasi yang alami. Hasil penelitian ini menunjukkan bahwa alih fungsi lahan mangrove menurunkan kemampuan penyimpanan karbon ekosistem dan diperlukan waktu untuk meningkatkan nilai simpanan karbon sedimen pada daerah yang pernah mengalami alih fungsi.
Optimization and improvement of recombinant chitinase biosynthesis in E. coli using response surface method
Authors: Thu Ha Trinh Thi , Quyen Dong Van , Binh Ngo Dinh 
Published: November 2018

Chitinases (EC 3.2.1.14) are enzymes that degrade chitin. These enzymes are gaining importance for their wide-ranging applications including the preparation of pharmaceutically important chitooligosaccharides and N-acetyl D glucosamine, preparation of single-cell protein, isolation of protoplasts from fungi and yeast, control of pathogenic fungi, treatment of chitinous waste, mosquito control and morphogenesis and especially in agriculture fields to control pathogens. Previously, we have cloned chiA gene encoding chitinase for overexpresion in E. coli. Herein, we optimized the expression conditions for improvement of chitinase biosynthesis in recombinant E. coli strain using response surface method (RSM) based on Design-Expert 10.1 software (Stat-Ease, Inc., Minneapolis, USA. Fermentation conditions such as inducer concentrate, induction time and cell density at the time of induction and their effects on the chitinase biosynthesis were investigated. The RMS analysis suggested that the optimal conditions for production of recombinant ChiA are at lactose concentration of 6,15 mM, 8,12 hours after induction and cell density OD600nm = 0,87 with predicted enzyme activity of 7,49 U/ml. The model obtained was used for fermentation of recombinant strain and the real chitinase activity achieved 7,54 U/ml which is 1.32 times higher compared to that of the pre-optimization (5.71 U/ml). The RSM was found to be useful in optimizing and determining the interactions among process variables in ChiA enzyme production. Our data also indicated that using lactose as the inducer instead of ITPG for ChiA expression can also reduce product costs. Citation: Trinh Thi Thu Ha, Dong Van Quyen, Ngo Dinh Binh, 2018.

Published: November 2018

Chile es el mayor productor de cobre en el mundo, y este metal es obtenido principalmente a partir de los sulfuros de cobre, utilizando los procesos clásicos de flotación y pirometalúrgicos. En nuestro país existen siete fundiciones de cobre, las cuales generan grandes volúmenes de escoria. Este trabajo presenta los resultados obtenidos de recuperación de cobre contenido en escorias de horno de reverbero (HR) y de convertidor Teniente (CT) de la fundición Hernán Videla Lira, de Paipote mediante flotación. A través de pruebas de flotación rougher a escala de laboratorio se determinó que la granulometría, para ambos casos, corresponde a 70% menor a 74 µm, lográndose recuperaciones de 59,2% escoria HR y 86,8% para la escoria del CT, cuyas leyes de cobre en el concentrado fueron de 3,7% y 23,6% respectivamente. Las dosis de reactivos utilizados fueron 40 g/t de F-703 como colector y 30 g/t de H-70 como espumante. Los tiempos óptimos de flotación de las etapas rougher y cleaner, de ambas escorias, se determinaron mediante cinéticas de flotación. Finalmente se realizaron pruebas a nivel industrial con los resultados de laboratorio alcanzándose una ley de 18,2% de cobre (recuperación de 56,1%) para escoria HR, y para la escoria CT se obtiene una ley de 39,1% de cobre con una recuperación de 91,4%

La nueva utilidad de la prostitución en el neoliberalismo
Authors: Gimeno Beatriz 
Published: November 2018

En este artículo se pretende explicar la transformación sufrida por la institución de la prostitución desde que en los años 70 y 80 se convierte en una de las industrias transnacionales más importantes del mundo. En esos años, al mismo tiempo que se convierte en una megaindustria sufre también una transformación en cuanto a su funcionalidad como institución patriarcal. Progresivamente está dejando de ser exclusivamente una manera de dividir a las mujeres en esposas/putas así como de justificar una determinada ideología sexual, y se está convirtiendo también en una manera de reasegurar las masculinidades más tradicionales, acosadas por los éxitos del feminismo. Al mismo tiempo también se está convirtiendo en el necesario alivio social para una población masculina a la que un neoliberalismo brutal ha situado en una situación en la que antes sólo se encontraban las mujeres.

Secondary Union of a Critical Segmental Femoral Defect
Authors: Davis Elizabeth , Vemulapalli Krishna C. , Hansen Denise , Kellam James F. , Achor Timothy S. 
Published: November 2018

Case:
We report the case of a 41-year-old man who sustained an open femoral shaft fracture with 10 cm of segmental bone loss in a motorcycle collision. He underwent serial irrigation and debridement procedures and intramedullary nailing of the fracture. He was lost to follow-up, but presented 9 months after the injury with abundant callus formation; at 11 months, the simple hypertrophic nonunion was treated with exchange nailing.

Conclusion:
Although unusual, secondary union of segmental femoral defects may occur. The mechanism by which this occurs is poorly understood, but is likely related to the biology of the fracture site, the effects of reaming, and the mechanics of the fixation.
Synthesis of Novel α-amidino Carboxylic Acids and their Use as H-Bond Catalysts in Strecker Reaction
Authors: Zaghari Zahra , Azizian Javad 
Published: November 2018

Aim and Objective:
A wide variety of synthesized amidine derivatives are bioactive
compounds. They show a vast range of medical properties. Therefore, a simple route for synthesis of
novel class of amidine derivatives called amidino carboxylic acids and their use as catalysts in
Strecker reaction has been reported in the current work. The stability, local charge density and
hydrogen bond parameters were calculated for eight derivatives with different substituents.

Materials and Methods:
In order to synthesize these amidino carboxylic acids, we initially prepared
Knovenogel condensation products via the reaction of isatin derivatives with malonitrile. When the
reaction was performed in water, the resulting nitrile groups of malonitrile derivatives was
hydrolyzed with HOAC/ H2SO4 to generate the desired amide groups. The amide groups in resulting
compound converted to amine groups with two Hoffman rearrangements in the presence of
NaOH/Br2. Further neutralization led to the final zwitterionic α-amidino carboxylic acids. In the next
step, the catalytic activity of these compounds as H-bond donor catalyst was investigated in Strecker
reaction.

Results:
The overall yields of the derivatives with substituent on the aromatic ring of starting isatins
are higher than that for the overall yields of nitrogen-substituted isatins. The reaction of 5-nitro isatin
with the next reagent gives lower yield in aryl-substituted products. An increase of catalytic activity
is observed by rising the electron-withdrawing power of the aromatic ring substituents., The
presence of nitro group in the structure of catalyst caused a large increase of catalytic activity in
Strecker reaction. DFT calculations at B3LYP/6-31++g(d,p) and Lanl2dz level of theory showed that
these compounds act as single H-bond catalysts and higher yields were obtained for complexes with
stronger hydrogen bond.

Conclusion:
A simple and efficient method for synthesis of ɑ-amidino carboxylic acids was
developed in this research. These compounds have been used as a single H-bond donor catalyst in
the Strecker reaction. DFT calculations were carried out to confirm the experimental results. The
obtained data from computations are in good agreement with experimental results.
Cannabis Associated “High” Cardiovascular Morbidity and Mortality: Marijuana Smoke Like Tobacco Smoke? A Déjà Vu/Déjà Vécu Story?
Authors: Manolis Theodora A. , Manolis Antonis A. , Manolis Antonis S. 
Published: November 2018

Background:
Cannabis use has increased over the past several years as some countries have
legalized its use for the treatment of certain medical conditions and/or for recreational use. Thus, concerns
have risen about potential adverse health effects. Increasing number of reports have associated
cannabis use with serious cardiovascular (CV) complications. Furthermore, there appears to be a likeness
in the harmful health effects, especially on the CV and respiratory systems, of cannabis smoking
to those of tobacco smoking.

Objective:
To review the CV effects of cannabis use and compare them with those of tobacco use.

Methods:
Articles were reviewed that were published in English literature reporting on cannabis and
cannabinoid pharmacology and their effects on the CV system and their consequences. Emphasis was
also placed on articles reporting on cannabis use in adolescents, exposure to secondhand smoke, its effect
on exercise and finally its inter-relationship and similarities with tobacco use.

Results:
With growing cannabis use, an increasing number of reports have emerged associating marijuana
use with serious and life-threatening CV complications, including acute coronary syndromes, potentially
lethal cardiac arrhythmias and ischemic strokes. There are certain similarities of the deleterious
CV and respiratory effects of cannabis smoking with those of tobacco smoking. Despite the difference
in the active ingredients (tetrahydrocannabinol vs. nicotine), each substance produces a plethora
of chemicals when smoked and these are largely identical; furthermore, due to different modes of
smoking, cannabis chemicals are retained in the body for a longer time. Of course, concomitant tobacco
and cannabis smoking is a perplexing factor in isolating damages specifically pertaining to cannabis
use, while the health risk is additive. Although the mechanisms producing CV harm may be
somewhat different between these two substances, the outcome appears similar, or even worse, as the
effects may emerge at a younger age.

Conclusion:
There is an increasing concern that, apart from the mental health problem with cannabis
smoking, societies may be facing another wave of a déjà vu/déjà vécu phenomenon similar to the tobacco
smoking story.

Authors: Palei Narahari Narayan , Vijayaraj Surendran , Lathasri Kuppam , Archana Devalapalli , Rajavel Ponnusamy 
Published: November 2018

Background:
Erlotinib hydrochloride is a novel drug for the treatment of lung cancer.

Objective:
The objective of the present study was to design an uncomplicated and precise reverse phase
high-performance liquid chromatography (RP-HPLC) method and optimize the chromatographic parameters
using response surface methodology derived from Box Behnken design. The optimized method was
validated for estimating Erlotinib from bulk and nanostructured lipid carriers (NLCs) formulation.

Methods:
Independent variables such as flow rate, injection volume and strength of the buffer were
optimized in order to decrease retention time and curtail asymmetry factor of Erlotinib. Forced degradation
studies were done to determine the stability of the drug. The developed method was validated as
per ICH guidelines.

Results:
The optimized strength of ortho-phosphoric acid buffer by blending with Acetonitrile (80:20
v/v), flow rate and injection volume were found to be 25mM, 1ml/min, 20µL respectively. Linearity
was observed in the concentration range of 1-6 µg/mL. The retention time of Erlotinib was found to be
3.717 minutes. The limit of detection and limit of quantification for Erlotinib were found to be
0.01ng/ml and 1ng/ml, respectively.

Conclusion:
The proposed method was found to be a simple and the best method for analysing
Erlotinib in nanostructured lipid carriers. Chemometric approach was employed as an effective tool for
optimising the chromatographic conditions of the proposed method.
NUCA-2A: A New Adaptive and Behavior Aware Block Placement Process
Authors: Souahi Mohamed Salah , Mohammed Mohamed Ben 
Published: November 2018

Background:
The last three decades were marked by a spectacular evolution of CPUs.
Both cores number on chip and shared Low Level Cache (LLC) size are increasing what makes LLC
the bottleneck's system. One major weakness of future cache memory hierarchies will be to carry out
memory blocks availability for vertical requests, with no consideration to horizontal proximity to
cores. Simulations show that some LLC accesses cost more latency cycles than off-chip accesses.

Objective:
This paper presents a new adaptive and blocks behavior aware process, called NUCA-2A.
It manages blocks in LLC in a purpose of reducing it's latency, and it's inner bandwidth, by studying
each block's behavior, and by placing it in the most suitable location among LLC banks.

Methods:
LLC accesses are classified basing on each one's specific behavior. Authors establish also
a two levels horizontal hierarchy in LLC. This work consists to place blocks in the zones that matches
the best their behaviors.

Results:
In contrast to the classic S-NUCA scheme, NUCA-2A makes a reduction of up to 60,39%
of global LLC latency as well as 40,74% of average inner traffic. It makes also an average speedup
of 17,89 % in term of number of instructions executed by cycle.

Conclusion:
Behaviors study gives encouraging results. Several methods are in use in different
fields to forecast a behavior basing on previous observations. We are working on a prefetching model
that permits blocks migration to and from privileged banks.
