Salah satu program yang dapat diselenggarakan dalam rangka pemberdayaan guru adalah supervisi akademik. Supervisi akademik merupakan upaya membantu guru – guru mengembangkan kemampuanya mencapai tujuan pembelajaran. Guru akan bekerja secara profesional apabila ia memiliki kompetensi yang memadai. Maksudnya adalah seorang guru akan bekerja secara profesional apabila ia memiliki kompetensi secara utuh. Seseorang tidak bisa bekerja secara profesional apabla ia hanya memenuhi salah satu kompetensi diantara sekian kompetensi yang dipersyaratkan.
Calculated Avoidance: Math Anxiety Predicts Math Avoidance in Effort-Based Decision-Making

Published: May 2019

Math anxiety – negative feelings towards math – is hypothesized to be associated with the avoidance of math-related activities such as taking math courses and pursuing STEM careers. Surprisingly, however, there is little experimental evidence for the math anxiety-avoidance link. Such evidence is important for formulating how to break this relation. Here, we hypothesize that math avoidance emerges when one perceives the costs of effortful math engagement to outweigh its benefits and that this perception depends on individual differences in math anxiety. To test this, we developed an effort-based decision-making task in which participants chose between solving easy, low-reward problems and hard, high-reward problems in both math and non-math contexts. Higher levels of math anxiety were associated with a tendency to select easier, low-reward problems over harder, high-reward math (but not word) problems. Addressing this robust math anxiety-avoidance link has the potential to increase interest and success in STEM fields.
Neural correlates of turn-taking in the wild: Response planning starts early in free interviews
Authors: Bögels Sara
Published: May 2019

Conversation is generally characterized by smooth transitions between turns, with only very short gaps. This entails that responders often begin planning their response before the ongoing turn is finished. However, controversy exists about whether they start planning as early as they can, to make sure they respond on time, or as late as possible, to minimize the overlap between comprehension and production planning. Two earlier EEG studies have found neural correlates of response planning (positive ERP and alpha decrease) as soon as listeners could start planning their response, already midway through the current turn. However, in these studies, the questions asked were highly controlled with respect to the position where planning could start (e.g., very early) and required short and easy responses. The present study measured participants’ EEG while an experimenter interviewed them in a spontaneous interaction. Coding the questions in the interviews showed that, under these natural circumstances, listeners can, in principle, start planning a response relatively early, on average after only about one third of the question has passed. Furthermore, ERP results showed a large positivity, interpreted before as an early neural signature of response planning, starting about half a second after the start of the word that allowed listeners to start planning a response. A second neural signature of response planning, an alpha decrease, was not replicated as reliably. In conclusion, listeners appear to start planning their response early during the ongoing turn, also under natural circumstances, presumably in order to keep the gap between turns short and respond on time. These results have several important implications for turn-taking theories, which need to explain how interlocutors deal with the overlap between comprehension and production, how they manage to come in on time, and the sources that lead to variability between conversationalists in the start of planning.
The compendium of self-enactable techniques to change and self-manage motivation and behaviour (v1.0)

Published: May 2019

Behaviour change techniques describe the content of behaviour change interventions, but do not adequately account for the actions that individuals must themselves undertake to successfully change or self-manage motivation or behaviour. This compendium of 123 self-enactable techniques fills this gap by combining behaviour- and motivation-regulation techniques across six existing classifications of behaviour change techniques and three scoping reviews, converting each into a self-enactable form with instructive examples to facilitate self-enactment. Qualitative feedback was gathered from intervention developers and the general public to improve the utility, congruence, and ease of self-enactability of technique definitions and instructive examples. This integrative index of self-enactable techniques can help intervention developers and individuals select appropriate self-directed techniques to self-manage motivation and behaviour. Future research with this compendium will expand on the number of behaviours covered by the instructive examples and link techniques with their potential impacts on theoretical determinants of behaviours.
Failure of a Spiral-Welded Water Pipe
Authors: Craft C. Howard
Published: May 2019

A 10-in. diam, spiral-welded AISI 1020 carbon steel pipe carrying water under pressure developed numerous leaks over a four mile section. The section was fabricated using submerged-arc welding from the outside surface. Each welded length of pipe had been subjected to a proof pressure approximately twice the specified design pressure and two-thirds the approximate yield point of the parent metal. No failures or leakage were observed during proof testing. Metallurgical examination corroborated visual checks, indicating a distinct lack of root penetration in the split areas. Splitting occurred as a result of inadequate root penetration. The most likely source of difficulty in the welding process was the linear speed. Probably, the failures would not have occurred in absence of the welding problem. Also, the pipe was inadequate for the specified design pressure, as well as the reported maximum system pressure.
Failure Analysis of a Collapsed Roof
Authors: Bradley Walter L.
Published: May 2019

A portion of the roof of a single story building collapsed during a thunder storm. A failure analysis was conducted to determine whether this structural failure was due to improper design, substandard construction materials, faulty erection, or extreme weather conditions. The failure analysis consisted of an onsite inspection, macrofractographic examination of the fractures where the girders were welded to the columns, macrofractographic examination of the fractured trusses, metallographic examination of the girder and truss materials, chemical analysis of the low-carbon steel girder and truss materials, and mechanical testing of the truss material. It was concluded that substandard structural components in combination with faulty construction was responsible for this service failure.
Corroded Leaky Stainless Steel Pipes
Authors: Naumann Friedrich Karl , Spies Ferdinand
Published: May 2019

Steel pipes, used for years in a food factory soft water preheater, were found to leak as a result of corrosion. The pipes, made of 18/8 steel, were immersed in steam maintained at 0.5 atm and 150 deg C. They carried desalinated process water, heating it to approximately 100 deg C. Inspection revealed a reddish-brown coating on the outside of the pipe with a few flat pitting holes and incipient cracks. Corrosion was also observed on the inner walls of the pipe, consisting of rust patches with pitting scars, branching out to predominantly transcrystalline cracks. In this case, leaking appears to be the result of a combination of pitting and stress corrosion, most likely due to chlorides. The factory was recommended to use molybdenum-alloyed steels (type 18/10 or 18/12) which are more resistant to local disruption of passivating films and pitting than molybdenum-free types such as 18/8.
Failure of a Stainless Steel Holding Tank
Authors: Parrington Ronald J.
Published: May 2019

A 5000-gal (20,000-L) hot-water holding tank fractured at a large automotive manufacturing plant. The tank was made from Type 304 austenitic stainless steel. The inner diameter of the tank displayed a macroscopic, web-like network of cracks that deceptively suggested intergranular stress-corrosion cracking. The problem, however, originated on the outside surface of the tank where a tensile stress (due to low applied stress and fabrication-induced residual stresses) accelerated the growth of numerous stress corrosion cracks that eventually broke through to the inner surface, causing leakage and ultimately failure.
Microstructural Manifestations of Fractured Z-Profile Steel Wires on the Outer Layer of a Failed Locked Coil Wire Rope
Authors: Ray Amitava , Dhua S.K. , Mishra K.B. , Jha S.
Published: May 2019

Locked coil wire ropes, by virtue of their unique design and construction, have specialized applications in aerial ropeways, mine hoist installations, suspension bridge cables, and so forth. In such specialty ropes, the outer layer is constructed of Z-profile wires that provide not only effective interlocking but also a continuous working surface for withstanding in-service wear. The compact construction and fill-factor of locked coil wire ropes make them relatively impervious to the ingress of moisture and render them less vulnerable to corrosion. However, such ropes are comparatively more rigid than conventional wire ropes with fiber cores and therefore are more susceptible to the adverse effects of bending stresses. The reasons for premature in-service wire rope failures are rather complex but frequently may be attributed to inappropriate wire quality and/or abusive operating environment. In either case, a systematic investigation to diagnose precisely the genesis of failure is desirable. This article provides a microstructural insight into the causes of wire breakages on the outer layer of a 40 mm diam locked coil wire rope during service. The study reveals that the breakages of Z-profile wires on the outer rope layer were abrasion induced and accentuated by arrays of fine transverse cracks that developed on a surface martensite layer.
Dezincification of Silicon Brass in Contact with Leaded Red Brass
Authors: Kenny Philip J.
Published: May 2019

After six years of service, three water shut-off valves on a copper water line in a residential building were found to be inoperative. Macroscopic examination of the valves after disassembly revealed that all three failed at the key that holds the spindle in the gate. In addition, the color near the key changed from yellow to red-brown. The gate was made from leaded red brass (85-5-5-5) while the spindle was made from silicon brass. It was concluded that the valves failed by dezincification resulting from bimetallic galvanic corrosion. It is common in the valve industry to use components made of different alloys in the same valve, but this is not the best approach for all applications.
Corrosion of Steel Pipes in a Closed-Loop Hot Water Heating System
Authors: Khan A.H.
Published: May 2019

A closed-loop hot water heating system at a museum in South Carolina was the subject of failure evaluation. The system consisted of plain carbon steel pipes (Schedule 40) made of ASTM A 106 or A 53 (ERW or seamless). The supply and return lines were made of the same materials. The fittings were mechanically threaded assemblies. Temperatures ranged from 150 to 155 deg F (65.6 to 68.3 deg C). Leaks in the system had reportedly initiated immediately after the building had been placed in service. The cause of corrosion inside the steel pipes was attributed to tuberculation caused by oxygen concentration cells and oxygen-pitting related corrosion. Both types of corrosion are due to the poor quality of the water and the lack of corrosion control in the water system.

Published: May 2019

Emergency response teams are accused with ensuring citizen safety from life-threatening events such as structural fires, gas leakages, vehicle accidents, and precarious material spills. While overseeing such occasions is dangerous, the release of precarious materials, such as toxic chemicals, into the atmosphere is particularly challenging. Upon landing in a scene, response teams must quickly identify the precarious substance and the contaminated area to limit exposure to nearby population centres. For airborne toxins, this appraisal is confounded by natural conditions, for example, alters in wind speed and course that can cause unstable, elevated swaggers to move powerfully. Without a way to dynamically monitor and assess atmospheric conditions during these events, response teams must conservatively predict the extent of the contaminated area, then orchestrate evacuations, and reroute traffic to ensure the safety of nearby populations. In this paper, we propose outfitting drone with Internet of Things (IoT) sensor platforms to enable dynamic tracking of precarious aerial swaggers. Augmenting drone with sensors enables emergency response teams to maintain safe distances during precarious identification, minimizing first response team exposure. Additionally, we integrate sensor-based particulate detection with autonomous drone flight control providing the capability to dynamically identify and track the boundaries of aerial swaggers in real time. This empowers specialists on call for outwardly recognize swagger development and better foresee and disconnect the effect zone. We describe the composition of our prototype IoT-enhanced drone system and describe our initial evaluations.

Published: May 2019

In this project we are comparing different architectures and adding the features that increases the efficiency of our architecture. Few of them are including multiplexers in the message digester, using different adder architectures in the required places, reducing the critical path by breaking the longest path and making them to operate parallelly. Use of multiplexers reduces the number of registers required in the message expander. It simply transfers the output of expander to compressor block in every clock cycle. Whenever the number of cycle is greater than 16, the multiplexer switches the select line so that the computed message digest to send as output to the compressor. Using of a carry save adder and adder array takes lesser time to perform addition than a pair of adders array. Finally we all know that reducing the critical path reduces the overall operation time and hence increases the efficiency. Considering all these factors in the design we are designing the microarchitecture for SHA-256 algorithm and obtain the RTL code for that architecture. We have also verified the design by designing a test-bench, and finally synthesized the design.

Mung bean known locally as “Masho” is a recent introduction in the Ethiopian pulse production and grown in few areas of the country and constrained by different biotic factors.However, the relative importance of each pest across locations has not been assessed and well profiled to sound management strategy. The objective of this study was to assess distribution and intensity of major pests on mungbean.The survey was made in 2016 and 2017 main cropping seasons following the main roads and accessible routes in each survey district (lowland areas of North Shewa Zone) and stops were made at every 5 -10 km intervals based on vehicles odometers as per mung bean fields available. Five stops were made in each mung bean field by moving “X” fashion at each stop interval using quadrants and data were collected from each. The result indicated that, Apion clavipes was most prevalent insect pest of mung bean in surveyed areas with maximum prevalence of 100%. Similarly, leaf blight and leaf spot were most prevalent diseases of mung bean in all districts. On the other hand, survey revealed that Cyperus spp. was frequently observed weed in both seasons with the highest weed density per m2. In 2017, weed Spps. Cyperus rotundus and Echinocloacolona L. were more frequently obtained weeds of mung bean in the surveyed districts with the consequent frequencies (77.42, 70.97%) and densities (16.11, 2.8 per m2). The current study indicated that a complex of pests exist on mung bean in the studied areas. Therefore, pest management strategies need to be devised.

Published: May 2019

The paper provides an analysis of the current situation in the Slovenian Armed Forces, identifies weaknesses and advantages, and offers recommendations for the organization and functioning of the Slovenian Armed Forces. We have also examined whether its transformation follows the transformational processes in the Alliance. NATO's DOTMLPF-I methodology and an analysis have been used to determine the weaker areas. We have particularly highlighted the field of personnel and finances that need to be improved in order to ensure a more effective implementation. By analyzing the development of military organizations in the future and by reviewing NATO's strategic concepts, we have established that in order to successfully function in the future, the Slovenian Armed Forces must follow the transformational imperatives of the Alliance today. Furthermore, we have analyzed the requirements lying ahead the Slovenian Armed Forces in the future and described some of the combined unconventional threats. At the end, we have also presented the recommendations for the operation of the Slovenian Armed Forces in the future, namely system consolidation, preparation of a vision, integration, modernization and flexible structure of units as well as financial stability and sustainability. As a fundamental finding of the article, we emphasize the fact that, by 2025 and beyond, the Slovenian Armed Forces should be shaped as a small but still sufficiently strong military force, which by using sustainable resources can provide highly qualified and trained joint forces that are interoperable with the armed forces of other NATO Allies.

De la Historia a los relatos. El patrimonio cultural como herramienta de comunicación abierta, participación ciudadana y desarrollo urbano
Authors: Rivero Moreno Luis David
Published: May 2019

En un mundo mayoritariamente urbano, la necesidad de mejorar las condiciones de vida en las ciudades se ha convertido en un debate prioritario a nivel global. Las ciudades comparten redes, retos y problemas en todas las latitudes casi sin variación. El patrimonio cultural aparece como un ámbito de impacto creciente a nivel político, social y económico en el desarrollo de urbano. Su propia resiliencia y resistencia al paso del tiempo, y su capacidad de activación de la memoria y los espacios comunes pueden ejercer de referente clave respecto a los objetivos expuestos en las agendas urbanas. Las instituciones deben permanecer abiertas a escuchar la voz de todos los grupos sociales, de la diversidad de comunidades e individuos que conforman la ciudad. Ese paso es crucial para que la ciudadanía adquiera un papel activo en el futuro del espacio que habitan. La ciudad debe ser escuchada y reescrita de un modo inclusivo. Esa narración tendrá necesariamente que ser asumida por los propios actores y relatores de la ciudad, sus ciudadanos.
Notas sobre ciudad, cultura y patrimonio

La ciudad vuelve a estar en primer plano. Más globalización y también más localización convierten a la ciudad y su entorno en el sitio en el que las cosas ocurren. Un espacio de posibilidades y como tal un espacio de conflictos. Hablar de ciudad ha sido siempre sinónimo de hablar de capacidades y de carencias. En la ciudad se enfrentan relatos distintos sobre proximidades y futuros. Culturas de la competencia y de la colaboración, de memoria o patrimonio, pero también de innovación y alternatividad. Culturas establecidas y culturas ocultadas o emergentes. Hablar de cultura urbana o de cultura de ciudad inevitablemente nos lleva a hablar de valores, de política. Las nuevas agendas urbanas han de ser capaces de incorporar estos elementos en su contenido.

HUMAN MORBIDITY IN THE CONDITIONS OF NATURAL GEOCHEMICAL ANOMALY THAT CAUSES NO ENDEMIC DISEASES
Authors: Mikheeva E V , Baytimirova E A , Kshnyasev I A
Published: May 2019

Geochemical and medical ecology studies were conducted in the areas of natural geochemical anomalies with excessive content of heavy metals (Ni, Cr, Co, Cu, Pb) in the Sverdlovsk region (the Middle Urals). The purpose of the work was to study the human morbidity rate in the natural geochemical anomalies (biogeochemical province), which, along with abnormally high content of heavy metals in the soil did not cause endemic diseases. Morbidity data were analyzed by generalized linear model device. The interpretable variable is arcsine-converted value of the cases number ratio to the study area population size. In the course of morbidity average data analysis covering five-year period it's statistically significant increase was stated on the territory of the natural geochemical anomaly (p < 0.001) in comparison with full tone. The main contribution to the morbidity rate increase in the geochemical anomaly make infectious and parasitic diseases, diseases of the circulatory system, respiratory, digestive. As s reason for the increase of morbidity rate is proposed the weakening of immunity under the influence of high concentrations of the chemical elements. Fixed non-specific effect of the natural geochemical factor is probably universal for abnormal areas of the earth's surface, characterized by the endemia absence.
MORPHOMETRIC PARAMETERS AND PROPETIES OF ERYTHROCYTE MEMBRANE UNDER THE INFLUENCE OF EXTREME PROFESSIONAL FACTORS

Published: May 2019

240 hot papas (age 25-47 years) took part in the research. They were divided into three groups depending on the length of service: 1-6, 7-15, 16-25 years. Red blood cells parameters were examined by means of the blood analyzer "Micros-60 OT", membrane deformability and osmotic fragility were determined according to special techniques at the beginning and at the end of the daily shift. The morphometric parameters of hot papas' erythrocytes corresponded to normal values. The workload during the day did not lead to their significant shifts except anisocytosis in the group with work experience of 16-25 years. The influence of service duration on increase of red blood cell heterogeneity, a reduction in their total number and Hb level was found in the same group. At the beginning of the shift the membrane deformability and osmotic fragility in 0.45 % NaCl solution were significantly lower in all surveyed groups than in the control group. The average values of these parameters increased in all groups by end of the shift. However, the control group values were not achieved.

The aim of the study was to find possible associations of polymorphic variants rs1800629 of gene TNFA and rs1837253 of gene TSLP with the development of occupational asthma. The analysis of polymorphism of cytokine genes was carried out by means of polymerase chain reaction of DNA synthesis in 83 patients and 195 control subjects. Genomic DNA was isolated from whole blood samples using standard phenol/chloroform extraction techniques. Statistical analysis was performed using χ test as amended by Yeats and odds ratios with 95 % confidence intervals. As a result, it found that in patients with occupational asthma allele C and genotype CC polymorphic locus rs1837253 TSLP gene occurs more frequently (OR = 1.91, 95 % CI 1.11-3.28; p = 0,026 и OR = 2.48, 95 % CI 1.29-4.77; p = 0.010 respectively) than in the control group. The analysis of the association of polymorphic locus rs1800629 TNFA gene with occupational asthma did not reveal statistically significant results. The received data suggest the possible involvement of rs1837253 polymorphism TSLP gene in the formation of occupational asthma.

For the first time dioxins (including 2,3,7,8-tetrachlorodibenzo-p-dioxin, TCDD) were revealed by high resolution chromatography-mass spectrometry in tissues of animals (rodents and fish) and abiotic samples (soil, sediment, snow) from the biotopes near the landfill with solid wastes ("Salariyevo", New Moscow). Profiles of congeners in soil samples, snow and sediment were well comparable. Parameters of "toxic equivalency quantity" (WHO-TEQ98) greatly exceeded the levels registered in Vietnam dioxin-contaminated areas (territories of ecocide) known to produce a so-called dioxin pathology among population. As to the MPC for soil the observed levels near landfill were almost 38 times higher than the standards set in Russia. The consequences of the pollutants influence on the state of animals reflected the manifestations of toxic effects on the whole organism and the chromosome apparatus, in correlations with the parameters of dioxins (WHO-TEQ98) and/or TCDD in their tissues and objects in their natural habitat. Changes of cytogenetic status of fish and rodents, morphometric parameters of fish age dynamics, the emergence of individuals with abnormal head structure - correspond to pathological processes and conditions that determine the pathogenesis of human dioxin pathology. Analysis of the data obtained illustrates the possibility of creating a universal methodical approach for screening the hazards of dioxins' low dozes for human health.

Authors: Hashempoor Davood
Published: May 2019

In this paper, deep drawing process of functionally graded sheet is investigated analytically and using finite element method. Using equations for deep drawing of isotropic sheets and governing equations of functionally graded materials, equations for deep drawing of functionally graded sheets are derived. Mechanical properties of the functionally graded sheet vary through the thickness of it according to the exponential law distribution. Punch force and axial stresses at the wall are calculated by this analytical method. Also, using this force in abaqus software, axial stresses at the wall are determined. The results of two methods were compared with each other and good agreement was obtained.

Wheat (Triticum aestivum L.) is one of the main foods globally. Nutrition problems associated with Zinc and Iron deficiency affect more than two billion individuals. Biofortification is a strategy believed to be sustainable, economical and easily implemented. This study evaluated the effect of combined Zn and Fe applied as foliar fertilizer to winter wheat on grain yield, quality, Zn and Fe concentration in the grains. Results showed that treatments containing high Fe increased the yield. Grain crude fat content remained unaffected. Crude fiber was enhanced up to three-fold by 60% Zn + 40% Fe5.5 (5.5 kg ha−1 of 60% Zn + 40% Fe). Moreover, 80% Zn + 20% Fe5.5 (5.5 kg ha−1 of 80% Zn + 20% Fe) was the best combination for increasing crude protein. Zinc applied alone enhanced Zn concentration in grain. In addition, Fe was slightly improved by an application of Zn and Fe in the first year, but a greater increase was observed in the second year, where 100% Fe13 (13 kg ha−1 of 100% Fe) was the best in improving Fe in grain. Foliar application of Zn and Fe is a practical approach to increase Zn and Fe concentration, and to improve the quality of wheat grains.
Dietary Flavonoids as Cancer Chemopreventive Agents: An Updated Review of Human Studies

Published: May 2019

Over the past few years, interest in health research has increased, making improved health a global goal for 2030. The purpose of such research is to ensure healthy lives and promote wellbeing across individuals of all ages. It has been shown that nutrition plays a key role in the prevention of some chronic diseases such as obesity, cardiovascular disease, diabetes, and cancer. One of the aspects that characterises a healthy diet is a high intake of vegetables and fruits, as both are flavonoid-rich foods. Flavonoids are one of the main subclasses of dietary polyphenols and possess strong antioxidant activity and anti-carcinogenic properties. Moreover, some population-based studies have described a relationship between cancer risk and dietary flavonoid intake. In this context, the goal of this review was to provide an updated evaluation of the association between the risk of different types of cancers and dietary flavonoid intake. We analysed all relevant epidemiological studies from January 2008 to March 2019 using the PUBMED and Web of Science databases. In summary, this review concludes that dietary flavonoid intake is associated with a reduced risk of different types of cancer, such as gastric, breast, prostate, and colorectal cancers.

Analysis on Mechanical Properties of Recycled Aggregate Concrete Members after Exposure to High Temperatures
Authors: Chen Zongping , Zhou Ji , Ye Peihuan , Liang Ying
Published: May 2019

In order to study the mechanical properties of recycled aggregate concrete (RAC) specimens after exposure to high temperatures, 120 RAC prism specimens, 57 reinforced recycled aggregate concrete (RRAC) specimens, and 56 steel reinforced recycled aggregate concrete (SRRAC) specimens were designed, involving two varying parameters such as recycled coarse aggregate (RCA) replacement percentage and temperature. The performance degradation of RCA materials, RRAC members, and SRRAC members after exposure to high temperatures was analyzed in depth. The research results show that after exposure to high temperatures the surface color of members may change from cinereous to gray-white. Some cracks may appear on surface of members and the mass of members may be lighter. With the increase of the experiencing temperatures, the bearing capacity (compressive, bending, and shearing) of RAC and its members are reduced, but their ductility and energy dissipation capacity have little effect on the change of high temperature. With the increase of the RCA replacement percentage, the mass loss ratio, ultimate bearing capacity, and peak deformation of each RAC and its members increase slightly, and the displacement ductility and energy dissipation capacity of the RRAC members decrease slightly. With the increase in replacement percentage of RCA, mechanical properties of RAC and their members have little effect after exposure to elevated temperatures, and the fluctuation range is within 20%.

Published: May 2019

The aminoethyl–chitooligosaccharide (AE-COS) was reported to inhibit human gastric cancer cell proliferation and human fibrosarcoma cell invasion. In this study, the role of AE-COS in down-regulation of proliferation of human lung A549 cancer cells was evaluated. It was found that AE-COS was able to reduce A549 cell proliferation to (32 ± 1.3)% at a concentration of 500 µg/mL. Moreover, AE-COS treatment caused suppression on COX-2 expression in a dose-dependent manner. Notably, the role of AE-COS in induction of cell apoptosis was observed via decreasing Bcl-2 expression and increasing caspase-3 and -9 activation. Accordingly, the antiproliferative effect of AE-COS was indicated due to suppression of cell proliferation and induction of cell apoptosis, suggesting AE-COS as a promising chemotherapy agent for treatment of lung cancer.
