Authors: Deepuppha Nunthiya , Khadsai Sudarat , Rutnakornpituk Boonjira , Wichai Uthai , Rutnakornpituk Metha
Published: January 2019

pH- and thermoresponsive nanocomposite composed of poly(N-acryloyl glycine) (PNAG) matrix and magnetite nanoparticle (MNP) was synthesized and then used for drug controlled release application. The effects of crosslinkers, e.g., ethylenediamine and tris(2-aminoethyl)amine, and their concentrations (1 and 10 mol%) on the size, magnetic separation ability, and water dispersibility of the nanocomposite were investigated. The nanocomposite crosslinked with tris(2-aminoethyl)amine (size ranging between 50 and 150 nm in diameter) can be rapidly separated by a magnet while maintaining its good dispersibility in water. It can respond to the pH and temperature change as indicated by the changes in its zeta potential and hydrodynamic size. From the in vitro release study, theophylline as a model drug was rapidly released when the pH changed from neutral to acidic/basic conditions or when increasing the temperature from 10°C to 37°C. This novel nanocomposite showed a potential application as a magnetically guidable vehicle for drug controlled release with pH- and thermotriggered mechanism.
The Study of a New Modified Bicanalicular Intubation for the Repairment of Traumatic Canalicular Laceration
Authors: Zhang Miaomiao , Li Bin , Zhang Ning
Published: January 2019

Introduction. To investigate the efficacy and safety of a modified bicanalicular intubation (MBCI) used in canalicular laceration.Materials and Methods. This study is a retrospective consecutive chart review. A total of 43 eyes from 43 patients (36 males and 7 females) who underwent canalicular intubation were enrolled. Success rate was determined at 6 months after the surgery. Anatomical success was determined by diagnostic probing and irrigation; functional success was determined by asking patients about tearing.Results. Irrigation of the lacrimal passages in all 43 eyes showed that they were free from obstruction. The anatomical success was 100%, and 37 eyes (86%) achieved functional success. 6 eyes (14%) could not achieve functional success because there were some residual symptoms under irritating conditions, such as wind or winter weather, among which 2 eyes had bicanalicular lacerations and 4 eyes had lower canalicular laceration before surgery. There were no other complications observed in this study.Conclusions. The MBCI was simple and safe for using in canalicular laceration.

Introduction. Sarcopenia is defined as the progressive loss of skeletal muscle mass, associated with aging. A multidisciplinary approach has been increasingly prioritized in elderly care. A technique that has been widely used by the seniors is acupuncture. Objectives. To analyse the effects of acupuncture in muscle strength and in inflammatory markers of older people with sarcopenia. Methods. The sample was composed by 53 elderly people, aged over 60 years. Inclusion criteria were as follows: male and female seniors, sedentary and who were not under acupuncture treatment during the survey period. Assessment of body composition, handgrip strength, and functional test and IL-6, IL-10, and TNF-α cytokines analyses were performed. After verification of the physical examination, the subjects were divided into two groups (sarcopenic and nonsarcopenic). The first group was then randomized (by drawing lot) to be further divided into two subgroups: G1, composed of sarcopenic elderly people who received acupuncture intervention, and G2, composed of sarcopenic elderly people who did not receive intervention. The nonsarcopenic elderly people composed the group 3 (G3) and did not receive acupuncture intervention. ANOVA Split Plot was performed for intergroup comparison. For intragroup evaluation, ANOVA was conducted for repeated measures. For the delta values, ANCOVA was performed with the pretest as covariant. A p<0.05 significance level was adopted. Results. 26 older people concluded the collections. There was no statistically significant difference between the G1 group and the other ones regarding the assessed variables (muscle mass, muscle strength, functionality, and inflammatory markers). Conclusion. The results allow us to infer that it is possible that the conducted intervention protocol has not produced any significant effects in the studied population. UTN number: RBR-8df2h4.

Published: January 2019

The main objective of the proposed research in this paper is introducing an extended version of the linguistic picture fuzzy TOPSIS technique and then solving the problems in enterprise resource planning systems. In this article, we use the uncertain information in terms of linguistic picture fuzzy numbers; the decision maker provides membership, neutral, and nonmembership fuzzy linguistic terms to represent uncertain assessments information of alternatives in linguistic multicriteria decision making (LMCDMs). In order to introduce the extended version of TOPSIS method, we defined a new hamming distance measure between two linguistic picture fuzzy numbers. Further, we apply the proposed method to problem of enterprise resource planning systems and discuss numerical implementation of the proposed method of LMCDM.
Numerical Experiments on Triaxial Compression Strength of Soil‐Rock Mixture
Authors: Zhao Yanxi , Liu Zhongxian
Published: January 2019

Soil‐rock mixture is a kind of unfavorable geologic material, and it is composed of low‐strength soil particles and high‐stiffness rock blocks. Mechanical properties of soil‐rock mixture were controlled by the internal mesoscopic medium, thus resulting in great difficulties of determination of mechanical parameters. In this paper, influences of rock content, mesoscopic features, and random distribution of mixture in soil‐rock mixture on its shear strength were discussed through discrete element numerical simulation of the laboratory triaxial test. Results demonstrated that, with the increase of rock content, the internal friction angle of soil‐rock mixture increased continuously, while the cohesion of soil‐rock mixture decreased firstly and then increased. The stress‐strain curve belonged to a nonlinear hardening type, which was close to soil characteristic. However, the shear strength was affected by mesoscopic medium of mixture particles significantly, resulting in the strong discreteness of strength, and only by large amounts of data statistics can we get a better regularity of strength. The research results can provide references to determine mechanical parameters of soil‐rock mixture.
“Crack, Reduce, and Implant”: A Safe Phaco Technique in a Case with Hard Brown Cataract
Authors: Toprak Ibrahim , Yaylali Volkan
Published: January 2019

This report describes two maneuvers in different steps of phaco surgery in a case with hard cataract, which provide debulking of the central dense nucleus and prevents posterior capsule rupture (PCR). In the current case, clear corneal incisions were created, and anterior chamber was filled with ophthalmic viscosurgical device (OVD). Anterior capsule was punctured, and capsulorhexis was completed. Nucleus was cracked into two halves following vertical groove formation. Core nucleus was hollowed sideward bilaterally in the capsular bag. Nuclear halves were removed from capsular bag, and each one was pushed to one side on the iris plane. Capsular bag was inflated with OVD, and intraocular lens (IOL) was implanted. Nuclear halves were removed in confidence. The presented maneuvers initially reduce dense nucleus load in the safe zone and allow surgeon to use IOL as a barrier to protect floppy posterior capsule from early steps of the surgery.

Published: January 2019

Low-frequency (<300 MHz) aperture array systems are one of the new trends in modern radio astronomy. Among the challenges they pose, the instrumental calibration is a key aspect requiring an accurate and reliable model of each element of such electrically large array. A full-wave electromagnetic analysis has been carried out for the lower frequency (30–80 MHz) array of the low frequency array (LOFAR) radio telescope taking into account the presence of soil ground, the mutual coupling between the antennas and the relevant receiver impedance loading effects. The impact of mutual coupling effects on the embedded element and array patterns is assessed for two subarray configurations with different degrees of sparseness. A simplistic array factor approach has been implemented as well to determine the accuracy in the antenna pattern evaluation with respect to the full-wave approach. Finally, results from an experimental campaign conducted by means of a micro hexacopter system show the reliability of the developed array numerical model.
Traffic Structure Optimization in Historic Districts Based on Green Transportation and Sustainable Development Concept
Authors: Wang Qiuping , Sun Hao
Published: January 2019

To perform the reasonable traffic structure in the historical districts and effectively alleviate the contradiction between limited traffic supply and rapid growth of the traffic demand in historical districts, a dynamic game model of traffic competition is established in this paper, aiming at the green transportation and sustainable development. Firstly, the logit model reflecting the sharing rate of the traffic mode is established by using the generalized cost method to quantify all the factors that influence the travel mode selection. Accordingly, a dynamic game model of complete information is established for the trip mode of historical districts, taking into account the economic sustainability, environmental sustainability, and social sustainability of the traffic development. The model is based on the goal of maximizing the generalized profit, and modeling with environmental pollution, energy utilization, and road service level as the common constraints of various traffic modes. By iterating the Nash equilibrium solution of the model, the optimal structure and the optimal share of the traffic modes in the historical districts can be predicted. Finally, the model presented in the study is verified by the historical districts of Academy Street in Zhengzhou city, China, and the optimal structure and optimal traffic share of each traffic mode in the block are obtained. By changing the constraint conditions of the model, two sets of different governance policies are compared and analyzed, and some feasible suggestions on improvement of traffic structure are also put forward. The research results can be the important reference for traffic planning in historic districts.
Quantitative Risk Evaluation Model of the Multilevel Complex Structure Hierarchical System in the Petrochemical Industry
Authors: Tang Yang , Shu Jiangjun , Li Wang , He Yin , Yang Yan , Sun Peng
Published: January 2019

In the petrochemical production system, the high‐risk items malfunction may lead to major accidents so that the risk level of the items has become the highest focus of attention for the enterprises in petrochemical industry. Based on structural composition and risk relationship, a risk evaluation framework of the petrochemical production system can generally be divided into subsystems (SS), components and parts (CP), failure modes (FM), risk types, and risk factors. So it is a characteristic of multilevel, complex structure, and lack of evaluation criteria that the evaluated object has in the process of risk evaluation. However, there are few targeted modeling and calculation methods to carry out quantitative risk evaluation in the face of the evaluated object. In order to achieve risk quantitative evaluation of the complex structure hierarchical system, a multilevel Borda model (MLBM) is presented innovatively by us based on the traditional Borda method in this study. Moreover, the MLBM are applied to realize quantitative risk evaluation of the main structure system of truss type crane on the offshore platform. In this case study, the equivalent risk value (ERV) and risk priority number (RPN) of the evaluated object with multilevel, complex structure, and inadequate evaluation criteria are calculated and the risk ties in the RPN are effectively reduced. Then, the quantitative risk results can clarify the risk level and distribution of the high‐risk items throughout the production system and provide data support for the development of risk control measures to better protect the production safety. Hence, the feasibility and practicability of the method are verified with the case study. The MLBM can be used to solve other comprehensive evaluation problems with a complex hierarchical structure as well.
Research on Simulation Method of Missile Adapter’s Separation Based on Combined Calculation
Authors: Chen Miao , Jiang Yi , Shi Shaoyan , Zeng Wei
Published: January 2019

In the background of a container-type vertical launch missile, the simulation method of adapter separation in different wind speeds is researched. Based on force analysis of the adapters during their separation from the missile, the dynamic and kinematics equations of the adapter separation are established. The adapter’s aerodynamic parameters at different attitudes getting from the numerical wind tunnel are chosen to be the input. Through the dynamic simulation of the separation process of the adapters, the simulation results are in good agreement with the experimental data. The trajectory and placement distribution of adapters are obtained during the analysis of force and motion stance at different wind speeds. Then the relative distances between the adapter and missile or launch facility are determined. At the same time, it can be estimated that the combined calculation will save about two-thirds of time compared with dynamic grid method computing, which provides a significant guidance for the simulation method of adapter separation.

Published: January 2019

We present zinc oxide (ZnO) particles obtained inside a porous silicon matrix in the same electrolytic process using a p-type silicon wafer in a hydrofluoric acid (HF) solution containing formaldehyde (CH2O) and hydrated zinc sulfate as additives. The X-ray diffraction pattern of the sample confirmed the presence of ZnO with a hexagonal-type wurtzite structure. Photoluminescence (PL) spectra of the samples, before and after the functionalization process, were measured to observe the effect of ZnO inside the porous silicon. The PL measurements of porous silicon functionalized with ZnO (ZnO/PS) revealed infrared, red, blue, and ultraviolet emission bands. The ultraviolet region corresponds to the band-band emission of ZnO, and the visible emission is attributed to defects. The results of the nitrogen adsorption/desorption isotherms of the PS and ZnO/PS samples revealed larger BET surface areas and pore diameters for the ZnO/PS sample. We conclude that ZnO/PS can be obtained in a one-step electrolytic process. These types of samples can be used in gas sensors and photocatalysis.

Published: January 2019

Aim. This study assessed the 24 h circadian rhythm of intraocular pressure (IOP) using a contact lens sensor in three groups of patients with open-angle glaucoma. Methods. This study was a monocentric, cross-sectional, nonrandomized, prospective, pilot study. Eighty-nine patients were enrolled: 29 patients previously underwent an Ex-PRESS mini glaucoma device procedure (Group 1), 28 patients previously underwent Hydrus microstent implantation (Group 2), and 32 patients were currently being treated medically for primary open-angle glaucoma (Group 3). Circadian rhythm patterns were considered with five circadian indicators: fluctuation ranges, maximum, minimum, acrophase (time of peak value), and bathyphase (time of trough value). A two-tailed Mann–Whitney U-test was used to evaluate differences between groups. Results. All subjects exhibited a circadian rhythm and a nocturnal pattern. The signal fluctuation range was significantly smaller in the surgical groups than in the medically treated group (Group 1 vs. Group 3, p=0.003; Group 2 vs. Group 3, p=0.010). Subjects who underwent the Ex-PRESS procedure (Group 1) exhibited significant differences compared with the drug therapy group (Group 3) with regard to the minimum value (p=0.015), acrophase (p=0.009), and bathyphase (p=0.002). The other circadian indicators were not significantly different among groups. Conclusions. Patients who underwent IOP-lowering surgery had an intrinsic nyctohemeral rhythm. Both surgical procedures, Ex-PRESS and Hydrus, were associated with smaller signal fluctuations compared with medical treatment.
Reflections on palliative sedation
Authors: Twycross Robert
Published: January 2019

‘Palliation sedation’ is a widely used term to describe the intentional administration of sedatives to reduce a dying person’s consciousness to relieve intolerable suffering from refractory symptoms. Research studies generally focus on either ‘continuous sedation until death’ or ‘continuous deep sedation’. It is not always clear whether instances of secondary sedation (i.e. caused by specific symptom management) have been excluded. Continuous deep sedation is controversial because it ends a person’s ‘biographical life’ (the ability to interact meaningfully with other people) and shortens ‘biological life’. Ethically, continuous deep sedation is an exceptional last resort measure. Studies suggest that continuous deep sedation has become ‘normalized’ in some countries and some palliative care services. Of concern is the dissonance between guidelines and practice. At the extreme, there are reports of continuous deep sedation which are best described as non-voluntary (unrequested) euthanasia. Other major concerns relate to its use for solely non-physical (existential) reasons, the under-diagnosis of delirium and its mistreatment, and not appreciating that unresponsiveness is not the same as unconsciousness (unawareness). Ideally, a multiprofessional palliative care team should be involved before proceeding to continuous deep sedation. Good palliative care greatly reduces the need for continuous deep sedation.
On desire, failure and fear: Utopia and dystopia in contemporary cinema
Authors: Klonowska Barbara
Published: January 2019

This article discusses different concepts of utopia and dystopia and their diverse fates in contemporary film, analysing their typical representations, popular themes and tropes. It argues that in the new cinema, utopia has practically disappeared, preserved in works nostalgically or ironically commenting on its demise, its place being appropriated by dystopias that tend to dominate the cultural imagination and that gradually evolve from politically driven narratives towards dystopian adventure movies. Referring briefly to The Mission (Joffé, 1986) and The Beach (Boyle, 2000), it shows the withdrawal of utopias from contemporary cinema and their residual presence in nostalgic or ironic returns, while the evolution of dystopias is illustrated with the presentation of The Hunger Games (Ross, 2012) and Elysium (Blomkamp, 2013). The dual shift, then, first from utopia to dystopia, and then from hard-boiled politics towards individual subjectivity and entertainment marks one of the most characteristic tendencies observable in contemporary dystopian cinema. Its increasingly individualist orientation and the character-driven rather than political focus lead in turn back to the reconsideration of the meaning, value and future of the very concepts of utopia and dystopia in contemporary culture and film.
Utopian labour in The Hunger Games
Authors: Norford Daniel
Published: January 2019

Using the post-Marxist framework of Alexander Kluge and Oskar Negt’s Geschichte und Eigensinn (History and Obstinacy) (Kluge and Negt [1981] 2014), this article contends that a utopian conception of labour grounded in the historically developed forces of human imagination and obstinacy underpins The Hunger Games (Ross, 2012) and its development of Katniss Everdeen’s relationship to her own alienated labour. By tracing the formal and thematic elements of this development, I argue that both Nancy Collins’s book and the adapted film indicate an abiding investment in the Kantian schema of cognition, in which the dialectical forces of conceptuality and intuition suggest the human imagination’s paradoxical threat to capitalist processes of reification. By invoking virtual alternatives to the alienating spectacle of the games, Katniss’s labour becomes a conduit for moving from the imaginary realm of utopian hope to its actualized manifestation. This manifestation is based not only on the capacity of the human imagination, but more specifically on the willingness of an alienated audience to construct connections between their own historical circumstances and the phantasmatic material provided by plot and narrative form. The article may be of interest not only to scholars of utopia, but also to those working in film and media studies, critical theory and continental philosophy.
Dystopian film on the edge of a food coma
Authors: Jameson Stacy M.
Published: January 2019

This article takes up the representation of cannibalistic foodways in dystopic science fiction films. Keeping with a Hollywood generic tradition, these are not moralistic or dramatic tales of taboo or human nature as might be found in horror films, but distinct explorations of industrialization, mass culture and capitalism and the effects of these phenomena manifest on the bodies of the populace. The benchmark text in this discussion is Soylent Green (Fleisher, 1973), wherein the human body processed into food represents the human turned into a commodity. Consumption in the film is a mechanism of destruction, and the cinematic spectacle concludes with repeated visions of containment and disaffection. By contradistinction, two contemporary texts – The Hunger Games (2012) and Cloud Atlas (2012) – rework the dystopian vision in ways that suggest a more optimistic turn. Of central concern throughout the article is a consideration of the cinematic spectacle as a potential political, visceral and/or affective force for change.
Abjection and the New Extreme of utopia
Authors: Ellis Cameron A. J.
Published: January 2019

While it is true that contemporary filmmakers are finding new resources to explore the topic of utopia, this exploration has occurred primarily within the confines of two genres: science fiction and fantasy. In many instances these films are guided by an appeal to the pop culture boom of the young adult sub-genre; these cinematic explorations tease out many of the themes of utopia previously underdeveloped such as young love and romance, maturation and growth. One thing that recent mainstream Hollywood productions do not develop or address is the sheer horror and pain that moving towards something better, i.e., utopia, entails. The transition or movement towards utopia is not seamless in any way but rather fraught with struggle, angst, schism, terror and even death. To examine these aspects of utopia, I turn to the so-called New Extreme genre of cinema, primarily out of France. Specifically, analysing À l’intérieur (Inside) (Bustillo and Maury, 2007) and Martyrs (Laugier, 2008), I argue that New Extreme cinema offers unconventional and unexpected lessons on the process of working toward utopia, lessons not foregrounded in more mainstream utopian cinema. I build my argument by weaving some existing criticism of utopian theory with themes from New Extreme cinema such as abjection, death, pain, suffering and torture. In my analysis I draw on the theory of abject as used in the work of Julia Kristeva.
Ghosts of the city: Utopia and the city in Bhooter Bhabishyat (2012)
Authors: Bagchi Barnita
Published: January 2019

This article analyses a recent iconic film of postcolonial Bengali and Indian cinema. Aneek Dutta’s 2012 smash-hit Bhooter Bhabishyat is a fantasy urban comedy that hinges on the punning word ‘bhoot’, which means both the past and ghost in Bengali. I show how the film carries powerful charges of the utopian principle of hope as analysed by Ernst Bloch, which finds expression in Dutta’s critique of neo-liberal predatory property development that dispossesses earlier denizens of the city. I analyse how in Bhooter Bhabishyat the mansion of ghosts becomes an inclusive reservoir of many aspects of Kolkata’s transculturality and utopian spirit and community, articulating hope against the backdrop of a dystopian present. The article draws particular attention to how crucial women’s agency is in resisting such predations of criminal real estate development. I further show how Bhooter Bhabishyat articulates the utopian principle of hope by situating itself firmly in the present of Kolkata, narrativizing elements such as Bengali rock bands and fashion shows, while also paying tribute to the past history and histories of Kolkata, including histories of classic Bengali cinema. The world of the ghosts in this film, the article argues, ties together past, present and future and reinvents them, articulating utopian hope.
Utopian visions for American independent filmmaking
Authors: Reznik David L.
Published: January 2019

Today’s American independent movie scene, like the contemporary world system, is plagued by political economic contradictions and crises. Thousands of indie filmmakers across the country find their works increasingly lost in a rapidly changing marketplace where cinematic supply, bolstered by a proliferation of digital production technologies and online distribution platforms, far exceeds audience demand. And yet, a group of besieged artists working in the shadows of Hollywood are envisioning a utopian tomorrow despite the unprecedented challenges they face today. In fact, these unsung directors, producers, and writers express enthusiasm about precisely the new business models, media shifts and social relations that are threatening their very livelihoods. They are using their filmmaking imaginations to engage in ‘dialectical dreaming’, a playful process of generating ideal possibilities out of everyday limitations. Examples from an ethnographic study of more than twenty such filmmakers living in Los Angeles include the invention of cognitive storytelling software to level the resource playing field, the development of completely collaborative film projects through crowd-sourcing, and the transformation of single-family households into creative community workspaces. These dialectical dreams of socialized means of production, collectively owned intellectual property, and public/private sphere synthesis are placed within the context of recent innovations in Marxist theorizing about utopia in the hopes of inspiring not only new forms of cinematic practice, but also radical action among creative professionals across the current socio-economic structure.
On Thomas Aquinas's Rejection of an 'Incarnation Anyway'
Authors: Do Vale Fellipe
Published: January 2019

In the recent literature on whether there would have been an incarnation if there had been no fall, Thomas Aquinas is often cited as arguing for a negative answer on the grounds that it is more fitting. Little attention, however, has been given to what fittingness amounts to for Thomas, or what relation this has to the primarily biblical reasons he gives for denying an incarnation without the fall. In this paper, I argue that the fittingness derives primarily from what kinds of conclusions can be drawn from the biblical text – fitting conclusions are those that, though short of necessary truths, nevertheless ought to be preferred over all of the possible alternatives because they best cohere with the nature of the scriptural canon. The answer to whether an incarnation would have occurred, for Thomas, is an example of one such biblical conclusion. I then place Thomas’ arguments in conversation with contemporary advocates in favor of an ‘Incarnation Anyway’ and show that their strategy of argumentation is actually accommodated by Thomas’ position, leaving it safe from criticism.
The Relationship Between School Principals' Leadership and Teachers' Organisational Commitment: A Systematic Review
Authors: POLATCAN Mahmut , CANSOY Ramazan
Published: January 2019

The aim of this study is
to conduct a systematic review of studies on the relationship between school
principals' leadership behaviours and teachers' organisational commitment. For
this purpose, 23 research articles indexed in WOS, ERIC, EBSCO, SCOPUS and
ULAKBİM databases between 2000-2017 in the Turkish context and selected through
certain criteria were collected for analysis. According to the results of the
studies examined, as school principals performed a higher level of leadership
behaviours, teachers' level of commitment to their schools increased. The
leadership behaviours that were prominent in these studies were having a common
objective and vision in school, forming a culture of cooperation, enhancing
communication and interaction, showing interest and appreciation of
individuals, supportive and constructive behaviours, being fair, creating a
working culture based on respect and trust, sharing responsibilities, and
managing and maintaining change in school. Moreover, in the studies, school
principals' organisational commitment was reported to be positively related to
transformational leadership, servant leadership and ethical leadership
behaviours. These leadership behaviours were also found to be important
predictors of organisational commitment.

The
goal of this study is to develop a valid and reliable assessment instrument for
determining the attitudes of secondary school students towards intangible
cultural heritage components. Items included in the assessment instrument are
prepared by researchers on the basis of their analyses about studies in related
literature and expert opinions they obtained. The study is carried out with a
total of 367 students studying in 6 different secondary schools in central
district, Bartın city. At the end of the statistical analyses, it is determined
that, items whose item-factor total and adjusted correlation coefficient is
over 0, 21, are statistically significant. Results of the scale’s explanatory
factor analysis showed that scale items are grouped under 5 dimensions (Social
Life, Traditional Arts, Cultural Conscious, Verbal Traditions, Information and
Practices about Nature and Universe). According to the results of confirmatory
factor analysis about factor structures, factor fit indexes are coherent. It is
determined that Cronbach alpha internal consistency of the scale in general is
.89. Findings obtained at the end of validity and reliability studies about the
scale show that Intangible Cultural Heritage Attitude Scale (ICHAS), which is
made of a total of 23 items, is a proper instrument for assessing the attitudes
of secondary school students towards intangible cultural heritages.

Polyploidy is a common phenomenon in plants, especially on the species of ferns. The objectives of thisresearch are to find out the variation of the ploidy levels, to know the effects on the stomata index and size ofstomata and spore in Adiantum raddianum. The materials used to conduct this observation of chromosomes numberwere made from root tips or young leaf tips (croziers). The modified squash method was used in microscopicpreparation. The result of the observation showed that there was a variation in ploidy levels from 2n = 2x (diploid) to2n = 7x (septaploid). It appeared to be general trend that the higher level the ploidy causes the lower the indexstomata but the bigger the stomata and the spore size.

Drought stress will result in decreasing the rate of water absorption by plant roots. This decrease will result indisturbances in plant growth, especially in a growing network includes the addition of Growth in dry mass, volume,length or area of cells resulting from the interaction of processes in plants through photosynthesis, respiration,transport, water relations and nutrient balance. Morphological and physiological responses of plants against stressand patterns of plant adaptation to different environments is very important especially for the purposes of cultivationand the prediction of the properties of responsive plant tersebut. Purpose of this research is to examine changes incontent klorofil a and b, and growth (number of leaves and plant height ) cocoa seedling age of 12 months atdifferent water stress.The study was conducted in the village of Plana Banyumas, Central Java Province, which lasted from January2007 to June 2008. Cacao tree used was 12 months in which the cocoa beans used for seeding of hybrid clonesderived from cocoa pods from the village of O, o Kulawi Donggala District of Central Sulawesi. Cocoa seedlingswere given three treatments of water stress that soil water content 75%, 50% and 25%. Observations of variablechlorophyll a and b,number of leaves and plant height after one month and two months of stress.The results showed drought effect on leaf chlorophyll content of seedlings of cocoa, where the plants grown on soilwater content of 50% have chlorophyll a and b are lower than those grown on soil water content 75%. The growth ofcocoa seedlings are best when planted with soil water content 75%, because the soil moisture content of 50% and25% of the number of leaves and plant height decreased

A weed is a plant that is considered to be nuisance and unwanted plant in human-controlled settings,especially farm field and garden. The weed that grow in surrounding of crop could decrease yield due to competitionoccur between weed and crop on nutrition, sunlight and water. Organic farming system which has been developednowadays is an environmental friendly organic farming system. The objective of this research is to determine weedcompetition on carrot using several kinds of organic fertilizer. Six treatments were used in this research, i.e., greenmanure, combination of green manure and EM, EM alone and control (without manure and EM). The weed wasgrowth together with carrot for 3 months. The parameters are wet weight and dry weight of carrot per meter square.The results show that manuring could increase weed competition which in turn wet weight and dry weight of carrotare decreasing. The highest competition between carrot and weed occurred in the treatment of combination betweenorganic manure which combines with EM. The added EM on organic manure could increase weed competition oncarrot.

Oleoresin cinnamon bark belonging to the phenolic compounds that are known to have potential as antioxidants. On the basis of the potential of these compounds may be used to prevent or repair tissue damage, whether caused by the factors of age and condition of oxidative stress hypercholesterolemia. This study aimed to obtain skin and bone collagen profile of Wistar rats at various ages after oxidative stress treated hypercholesterolemia and oleoresin from the bark of cinnamon (Cinnamomum sp). This study used 54 male Wistar rats with body weight (200 ± 5 g), which are grouped into six treatment groups combined with the three age groups of mice that is three, six or nine months with three replications. Each group received treatment oleoresin and hypercholesterolemia. Giving oral oleoresin conducted on rats given oral way during the 7 days with a dose of 12 rats mg/200-gr bw / day. Hypercholesterolemic rats was conducted by feeding cholesterol content within 1% during the two months. The results showed that the profile of skin and bone collagen content of the highest found on threemonth old rats treated with oleoresin, oleoresin hypercholesterolemia and given again (P6, 2), namely 57.44 tg / mg and 33.47 tg / mg, while the profile of skin and bone collagen content of the lowest found in rats aged 9 months to get treatment without treatment of hypercholesterolemia oleoresin (P2, 9), namely 28.26 tg / mg and 10.65 tg / mg. From this research can be concluded that the condition of hypercholesterolemia and duration of the aging effect on skin collagen levels decrease and bone, and vice versa oleoresin at the age of young rats that received the treatment of oxidative stress could repair or prevent hypercholesterolemia decreased content of skin collagen and bone. In general, the rats are treated oleoresin and young age profile of the collagen content of skin and bones better compared with rats that do not get treatment in conditions of oxidative stress oleoresin hypercholesterolemia.
