Authors: Rosleine Dian , Suzuki Eizi , Sundawiati Atih , Septiana Wardi , Ekawati Desy
Published: July 2016

Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarifyvegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 x 10 m2 in abandoned plantation and 11 of 20 x 20 m2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swieteniamacrophylla –Agathisdammaa community in abandoned plantation where had a land use history of clear felling.Maesopsiseminii–Cyathea spp. community had a history of severe human disturbance. Fagaceae-Schimawallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses, and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery.

We studied the floristic composition and structure of the logged-over peat swamp forest in the  PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been  set aside by the company.  In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect,  thus covering a sampled area of 1-ha.  The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness.  The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth.  Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high  (3.05)  Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46  %).  The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and  D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed  strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium  and based on this association combined  with high IVs, the two parameters of species  characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and  Gonystylus bancanus vulnerable, hence they should  be protected.
CERCOSPORA BRUNFELSIICOLA (FUNGI, MYCOSPHAERELLACEAE), A NEW TROPICAL CERCOSPOROID FUNGUS ON BRUNFELSIA UNIFLORA
Authors: Hidayat Iman , Meeboon Jamjan
Published: July 2016

Cercospora brunfelsiicola on Brunfelsia uniflora is proposed as a new species based on a combination of molecular phylogenetic and morphological data analyses. The molecular phylogenetic analysis based on combined multilocus analyses of the Internal Transcribed Spacer (ITS), part of the elongation factor 1–a gene (EF1–a), and part of the calmodulin (CAL) gene regions showed that C. brunfelsiicola is phylogenetically distinguishable from other Cercospora species, including members of the C. apii s. lat. complex. Morphologically, C. brunfelsiicola differs from other closely related Cercospora species, in particular C. acaciae-mangii, by forming lesions with indistinct margin, larger stromata [(32) 48.5 ± 10.6 (68) ?m diam.], and filiform to narrowly obclavate conidia [(45) 59 ± 9.1 (72) × (2.5) 2.5 ± 0.2 (3) ?m].
FLORA OF BALI: A PROVISIONAL CHECKLIST
Authors: Van Balgooy Max M. J. , Widjaja Elizabeth Anita
Published: July 2016

Compared to Java the flora of Bali is poorly known. A checklist has been prepared based on literature and collections. The focus is on indigenous species, but the distinction between indigenous and naturalized species is not always clear. This checklist is therefore very provisional. The flora of the much smaller island state Singapore is much richer, probably mainly due to undercollecting of Bali.
TAXONOMIC PROBLEMS ON FOUR SPECIES OF PONTELLA (COPEPODA, CALANOIDA) DESCRIBED BY A. SCOTT (1909) IN INDO-MALAYAN WATERS
Authors: Mulyadi Mulyadi
Published: July 2016

ABSTRACTFour species of Pontella, i.e., P. alata, P. cerami, P. denticauda, and P. forficula, which were originally described by A. Scott (1909) were found from Indo-Malayan waters. Some misidentifications resulting in wrong species identity were discovered on P. cerami and P. forficula. Pontella cerami A. Scott, 1909, described based on two male specimens from the Banda Sea, Indonesia is here recognised as the male of P. alata. Similarly, P. forficula, also known from twomale specimens from the Sulu Sea, Philippine must be reassigned as the male of Ivellopsis elephas (Brady, 1883). Another Indo-Malayan Pontella, i.e., P. denticauda A. Scott, 1909 must also be moved to the genus Ivellopsis Claus 1893, as Ivellopsis denticauda (A. Scott, 1909) by its having posterior corners of Pdg5 produced into rounded lobes in both sexes; particularly in the female, by (1) the genital double-somite with a large lateral process, (2) the CR asymmetrical with the right ramus longer than the left, and (3) the Re of P5 with 3 apical spines and with an acuminate Ri. The male has, (1) the CR asymmetrical with right ramus slightly longer than the left, and (2) the thumb of Re2 of right P5 is elongated, and (3) the Re2 of the left P5 bifurcate at apex.Descriptions, measurements and figures of the four species are given, along with a review of their distribution and that of their species groups over Indo-West Pacific waters, together withtaxonomic remarks and synonymies in each case.Key words : Copepoda, Indo-Malayan, Pontella, small islands, taxonomy

Authors: Hadisuwarno Wiharjo , Setyoningrum Retno Asih , Umiastuti Pirlina
Published: July 2016

Background Pneumonia has been one of the serious problems for children under five in Indonesia. Imbalanced interactions among host factors, agents, and environments influence incidence of pneumonia. Objective To determine the risks of the host related to the incidence of pneumonia in children aged 3-59 months in Pediatrics Department, Dr. Soetomo General Hospital during 2011-2012. Methods This was a case control study on medical records of patients with respiratory infections in Pediatrics Department, Dr. Soetomo General Hospital. We grouped patients with pneumonia as the case group and patients with other respiratory infections as the control group. The data were statistically processed to calculate odds ratios and P values. Results There were 326 subjects reviewed, 163 in the case group and 163 in the control group. Host factors that increased the risk of pneumonia were: low birth weight (OR=3.10; 95%CI 1.34 to 6.86), inadequate exclusive breastfeeding (OR=1.7; 95%CI 1.09 to 2.64), malnutrition (OR=3.44; 95%CI 2.12 to 5.58) and incomplete immunization in a certain period of age (OR=2.70; 95%CI 1.72 to 4.24). Existed comorbidity was unrelated to the incidence of pneumonia (OR=1.53; 95%CI 0.86 to 2.71). Conclusion Low birth weight, inadequate exclusive breastfeeding, malnutrition, and incomplete immunization in a certain period of age increase the risk of pneumonia.
Lead poisoning and cystatin-C in children
Authors: Yuri Yuri , Najoan Praisilia Riani , Gunawan Stefanus , Umboh Adrian
Published: July 2016

Background Lead pollution is a global problem both in developed and developing countries. Lead poisoning is associated with decreased glomerular filtration rate (GFR) and is a risk factor for acute kidney injury (AKI). Serum cystatin-C is a more precise test of GFR than serum creatinine level, as serum cystatin-C levels rise earlier than serum creatinine, when GFR decreases. Objective To assess for a possible correlation between lead poisoning and cystatin-C levels in children. Methods We conducted a cross-sectional study in children aged 6-11 years with a history of lead poisoning from elementary schools in Talawaan District, North Minahasa Regency from July to October 2013. Cystatin-C and blood lead levels (BLL) were measured in all subjects. Spearman’s rho test was used to analyze a potential correlation between BLL and cystatin-C level. Results This study included 41 children, comprising 21 boys and 20 girls. Their median age was 8.50 (range 6.8-10.7) years. Elevated levels of cystatin-C did not exceed normal values, however, we found a positive correlation between BLL and cystatin C (r=0.419, P=0.006). Conclusion There is a positive correlation between BLL and cystatin C level in children with lead poisoning. Regular monitoring of BLL, medical intervention, and an epidemiological study to help find the sources of contamination are needed for children with lead poisoning.

Authors: Kuntartiwi Dyahris , Yanuarso Piprim Basarah , Sastroasmoro Sudigdo
Published: July 2016

Background Pulmonary arterial hypertension (PAH) is a common complication seen in those with a left-to-right shunt congenital heart defect (CHD). Corrective procedures by surgery or catheterization are the therapies of choice for reversible PAH. Since morbidity and mortality due to PAH after correction is high, sildenafil has been used as a selective vasodilator of the pulmonary artery, in order to decrease pulmonary arterial pressure. Objectives To evaluate the effect of sildenafil on pulmonary arterial pressure and clinical outcomes after left-to-right shunt CHD corrective procedures. Methods Left-to-right shunt patients aged < 18 years scheduled for corrective treatment were randomized in a double-blind fashion, to receive either oral sildenafil or placebo, given on days 3 to 30 after the corrective procedure. Clinical and pulmonary arterial pressures were evaluated by echocardiography before, 3 days after, and 30 days after the corrective procedure. Results From July 2013 to June 2014, 36 patients were included in the study: 17 in the placebo and 19 in the sildenafil groups. There were no differences in pulmonary arterial pressure or in clinical outcomes after corrective procedure between the two groups. There were no adverse events during the treatment. Conclusion Sildenafil has little effect on decreasing pulmonary arterial pressure, as most of our subjects seem to have hyperkinetic PAH. As such, pulmonary arterial pressure returns to normal soon after corrective procedures.

Authors: Karmila Ariesta , Nazir Muhammad , Yangtjik Kiagus , Yuwono Yuwono
Published: July 2016

Background Vitamin D deficiency and vitamin D receptor (VDR) gene polymorphisms are strongly associated with tuberculosis (TB) susceptibility in countries with four seasons. As a country with sufficient sunlight for vitamin D production in skin, the incidence of TB in Indonesia remains high. Objective To assess for possible associations between the incidence of tuberculosis and serum vitamin D level, as well as VDR FokI polymorphisms in children. Methods A case-control study was conducted at the Department of Child Health, Dr. Mohammad Hoesin Hospital, Palembang from November 2011 to April 2012. Subjects were children with TB (the case) and children without TB who had been exposed to TB in the home (the control). Serum vitamin D [1,25(OH)2D3 or calcitriol] level was measured by immunodiagnostic system (IDS) 1,25-dihydroxy vitamin D enzyme immunoassay (EIA) kit. The VDR FokI polymorphisms were identified by polymerase chain reaction (PCR) and restriction-fragment length polymorphism (RFLP) analysis. Results Sixty subjects was divided equally into the case and control groups. The mean serum calcitriol level in the case group was significantly lower than that of the control group [105.5 (SD 66.9) pmol/L vs. 162.9 (SD 52.9) pmol/L, respectively; (P=0.001)]. We found 9 subjects with calcitriol deficiency, 8 in the TB group and 1 in the healthy contact group (OR 10.5; 95%CI 1.2 to 90.7) The VDR FokI polymorphism was seen in 28 subjects in the case group and 22 in the control group (OR 5.0; 95%CI 0.9 to 26.4). Conclusion Vitamin D (calcitriol) deficiency and lower serum levels are associated with higher risk of TB in children. The VDR gene FokI polymorphism also contributes to susceptibility for TB.
Serum prolactin for differentiating epileptic seizures in children
Authors: Mangunsong Harry
Published: July 2016

Background Serum prolactin level has been used as a marker to differentiate epileptic from non-epileptic seizures in adults. Electroencephalogram (EEG) examination is the primary diagnostic tool used to assess seizures. However, EEGs are quite difficult to perform in children and have sensitivity of only 50%- 55%, with 96% specificity. Objective To assess the diagnostic potential of serum prolactin level as an alternative tool for children for differentiating between epileptic and non-epileptic seizures. Methods This diagnostic study was performed between January 2013 and December 2013. Thirty patients aged 3 months to 15 years with seizures and without fever who visited the Emergency Department of Arifin Ahmad Hospital, Pekanbaru, Riau, were included. Blood specimens were collected within 2 hours after seizure. Subjects underwent serum prolactin measurements and EEG examinations. Results Fifteen subjects had normal EEGs and 15 subjects had abnormal EEGs. Post-ictal serum prolactin levels were significantly higher in the epileptiform EEG group. The mean serum prolactin levels were 23.78 (SD 21.86) ng/mL and 10.57 (SD 5.62)ng/mL in patients with epileptic and non-epileptic patients, respectively. Using a prolactin cut-off point of 17.2 ng/mL, serum prolactin had a 73.3% sensitivity and 93.3% specificity for differentiating between epileptic and non-epileptic seizures. Conclusion Our findings suggest that serum prolactin level increases after an epileptic seizure, but not after a non-epileptic seizure. Post-ictal prolactin elevation within 2 hours may be useful in differentiating epileptic seizures from non-epileptic seizures.

Authors: Rossanti Rini , Gurnida Dida Akhmad , Fadlyana Eddy
Published: July 2016

Background Obesity in adolescents is a major health problem and has been associated with low academic achievement. Brainderived neurotrophic factor (BDNF), a neurotrophin, plays a role in appetite suppression and memory, and its secretion is enhanced by physical activity. This neurotrophin may be associated with academic achievement in obese. Objective To compare physical fitness and serum BDNF levels to short term memory levels in obese adolescents aged 10–14 years. Methods This comparative, cross-sectional, analytic study was carried out on 40 elementary and high school students in Bandung, West Java, who were recruited by stratified random sampling. Short term memory was assessed by a psychologist using the Wechsler Intelligence Scale for Children-III Digit Span test (WISC-III Digit Span). Physical fitness was assessed by a clinical exercise physiologist using the Asian Committee on the Standardization of Physical Fitness Test (ACSPFT). Serum BDNF levels were measured by ELISA test in a certified laboratory. ANOVA test was used to assess for a correlation between serum BDNF concentration and short term memory, as well as between physical fitness level and short term memory. Pearson’s correlation test was used to analyze for a correlation between serum BDNF and physical fitness levels. Results The majority of subjects were in the physical fitness categories of moderate or poor. Subjects had a mean BDNF level of 44,227.8 (SD 10,359) pg/mL. There was no statistically significant difference in physical fitness with either serum BDNF or with short term memory levels (P=0.139 and P=0.383, respectively). Also, no correlation was determined between serum BDNF and physical fitness levels (r=0.222; P=0.169). Conclusion In obese adolescents, short term memory levels are not significantly different between physical fitness levels nor between serum BDNF levels.

Published: July 2016

Background Childhood obesity is associated with increased risk of cardiovascular diseases and metabolic syndrome, such as insulin resistance. Clinically, insulin resistance may be manifested as acanthosis nigricans. Resistin has a biological activity that is important in glucose and lipid metabolisms and closely related to the incidence of insulin resistance.Objective To find out the association of resistin level with scale of acanthosis nigricans in adolescents obesity.Methods A cross-sectional study was conducted on 53 obese adolescents with acanthosis nigricans in senior high schools in Padang, West Sumatera. Degree of acanthosis nigricans was assessed using scale of Burke and then plasma resistin level was performed with ELISA. Data were analyzed using ANOVA and post-hoc test.Result The mean of resistin level in obese adolescents was 14.21 (SD 7.43) ng/dL. High resistin level was found in scale of acanthosis nigricans 2,3 and 4 (P=0.0001). Obese adolescents with severe degree of acanthosis nigricans has higher resistin level compared to milder acanthosis nigricans.Conclusion In obese adolescents, the higher degree of acanthosis nigricans, the higher level of plasma resistin.

Noonan syndrome (NS; OMIM#163950) is a relatively common autosomal dominant disorder with a worldwide prevalence of approximately 1:1,000 to 1:2,500. The syndrome is characterized by distinctive facial features, congenital heart defects (CHD), and short stature. Distinctive facial features consist of a broad and high forehead, hypertelorism, downslanting palpebral fissures, a high arched palate, low set and posteriorly rotated ears with a thick helix, and a short neck with excess nuchal skin and low posterior hairline. Additional relatively frequent features include chest deformities, cryptorchidism in males, mild intellectual disability, and bleeding diathesis.1,2In 2001, missense mutations in
Density distribution functions of faults and scaling relations
Authors: Caputo Riccardo , Caputo Michele
Published: July 2016

In the present note, we analyse various seismological datasets collected in different geological and tectonic settings as well as at different time and space scales, like seismic sequences, regional background seismicity, aftershock sequences, microseismic data, and swarms and induced seismicity. We investigate these datasets in terms of statistical distribution of single parameters focusing on stress drop (Î”Ïƒ), scalar seismic moment (M0) and fault's dimension (often referred to as faults' radius, r0). In particular, we systematically obtain the density distribution functions (ddfs) of each parameter verifying the possible extension of the regression curves. We also analyse the correlations between the investigated parameters by comparing the slopes of the ddf for each dataset. Another goal of this investigation is to verify a possible similarity between comparable and different datasets (i.e. collected in similar or different geological and tectonic settings and range of magnitudes), to verify the stability of the ddf when using different methods as well as the variability of the stress drop even in the same seismological region. We suggest that even more accurate data covering wider ranges of values would be desirable in order to be of practical use like seismotectonic characterization, ground motion prediction and seismic hazard analyses, while the representation of the seismicity for any seismogenic region should be not limited to the b (or b0) value of the Gutenberg-Richter curve.

Published: July 2016

This article discusses the concepts of omission and commission as marketplace trauma within the theoretical framework of cultural trauma theory. The authors identify the meanings and processes of the people, activities, and outcomes likely when marketplace omission and/or commission occur, as well as the factors that elevate these events from collective to cultural trauma. The authors use concepts of social structure, collective practices, and collective discourse in exploring the interconnectivity of marketplace traumas and their actors, victims, and consequences (i.e., constrained consumption, damaged marketing systems, and institutional privilege). They then leverage the same framework to propose further research and corrective actions.

Published: July 2016

We review theoretical aspects of the studies on the recently discovered BiCh2 (Ch=chalcogen) based superconductors. We first focus on the electronic band structure, the Fermi surface and their correlation with the lattice structure. We then discuss the phonon features and the issue of the lattice instability. Finally, we survey the phonon-mediated as well as the unconventional pairing mechanisms that have been proposed so far.
Nambu-Goldstone-Leggett modes in multi-condensate superconductors
Authors: Yanagisawa Takashi
Published: July 2016

Multi-gap superconductors exhibit interesting properties. In an N-gap superconductor, we have in general U(1)N phase invariance. This multiple-phase invariance is partially or totally spontaneously broken in a superconductor. The Nambu-Goldstone modes, as well as Higgs modes, are important and will play an important role in multi-condensate superconductors. The additional phase invariance leads to a new quantum phase, with help of frustrated Josephson effects, such as the time-reversal symmetry breaking, the emergence of massless modes and fractionally quantized-flux vortices. There is a possibility that half-flux vortices exist in two-component superconductors in a magnetic field. The half-quantum flux vortex can be interpreted as a monopole, and two half-flux vortices form a bound state connected by a domain wall. There is an interesting analogy between quarks and fractionally quantized-flux vortices in superconductors.
Nonmedical Prescription Opioid and Heroin Use Among Adolescents Who Engage in Sports and Exercise
Authors: Veliz Philip , Boyd Carol J. , McCabe Sean Esteban
Published: July 2016

OBJECTIVES:

Previous research has found that adolescent athletes may be at increased risk of nonmedical prescription opioid use (NPOU) due to injuries. Although adolescent athletes are at an increased risk of engaging in NPOU, it has yet to be determined if they are also at greater risk for heroin use. The major purpose of this study was to examine both the trends in prevalence rates and patterns of initiation in lifetime NPOU and lifetime heroin use among adolescents who engage in sports and exercise.

METHODS:

Eighteen cross-sections of eighth and 10th graders were used from the Monitoring the Future study. The sample consisted of 191 682 respondents who answered questions on past-year participation in sports and exercise, lifetime NPOU, lifetime heroin use, age of NPOU onset, and age of heroin onset.

RESULTS:

The trends in NPOU and lifetime heroin use among adolescents who engage in sports and exercise has declined between 1997 and 2014. Logistic regression analyses found that adolescents who engage in sports and exercise had lower odds of reporting lifetime NPOU and heroin use compared with adolescents who did not engage in these activities during the past year. Analyses among lifetime heroin users found that adolescents who engage in sports and exercise had lower odds of initiating NPOU before heroin when compared with their peers who did not engage in these activities in the past year.

CONCLUSIONS:

Daily participation in sports and exercise may serve as a protective factor with respect to NPOU and heroin use.

This Policy Statement was reaffirmed September 2021.

Injury is still the number 1 killer of children ages 1 to 18 years in the United States (http://www.cdc.gov/nchs/fastats/children.htm). Children who sustain injuries with resulting disabilities incur significant costs not only for their health care but also for productivity lost to the economy. The families of children who survive childhood injury with disability face years of emotional and financial hardship, along with a significant societal burden. The entire process of managing childhood injury is enormously complex and varies by region. Only the comprehensive cooperation of a broadly diverse trauma team will have a significant effect on improving the care of injured children.

Postural tachycardia syndrome (POTS), inappropriate sinus tachycardia (IST) and vasovagal syncope (VVS) are relatively common clinical syndromes that are seen by physicians in several disciplines. They are often not well recognised and are poorly understood by physicians, are associated with significant morbidity and cause significant frustration for both patients and their physicians. The2015 Heart Rhythm Society Expert Consensus Statement on the Diagnosis and Treatment of Postural Tachycardia Syndrome, Inappropriate Sinus Tachycardia and Vasovagal Syncopeprovides physicians with an introduction to these disorders and initial recommendations on their investigation and treatment. Here we summarise the consensus statement to help physicians in the management of patients with these frequently distressing problems

Thromboangiits obliterans (Buerger’s disease) is a non-atherosclerotic, segmental inflammatory and obliterative disease affecting small and medium sized arteries and veins. The etiology is still unknown, but it is in close relationship with tobacco use. Symptoms begin under the age of 45 years and the undulating course is typical. Patients usually present with acute and chronic ischemic or infectious acral lesions. Diagnosis is usually based on clinical and angiographic criteria and it is important to exclude autoimmune disease, thrombophilia, diabetes, and proximal embolic sources. Even though Buerger’s disease most commonly involves the arteries of the extremities, the pathologic findings sometimes affect the cerebral, coronary and internal thoracic, renal and mesenteric arteries as well. The authors present the history of a patient with known Buerger’s disease and acute ischemic stroke. Brain imaging detected acute and chronic ischemic lesions caused by middle cerebral non-atherosclerotic arteriopathy on the symptomatic side. Other etiology was excluded by detailed investigations.

Natural shading and productivity index of broiler chickens
Authors: Souza Fernando A. , Milani Adhemar P.
Published: July 2016

The appropriate use of natural resources in the design of broiler houses provides a reduction in farming operating costs and optimization of production conditions. Therefore, the natural shading around the broiler house can be an alternative for improving internal conditions of comfort. This study verified the efficiency of natural shading in the broiler productivity index (PI) in East-West oriented commercial housings. The PI of 32 commercial broiler houses in five flocks divided throughout a year was compared. The sheds had the same management, density and the same structural features, except from tree shading: on the North face; on the South face; on both faces and without shading. It was observed that broiler house in East-West direction with shading on the South face had higher productivity index compared to houses with shading only on the North face or on both sides, between autumn and spring. For the summer period, sheds without shading showed productivity indexes superior to others.

Published: July 2016

Over the last 10 yr, California has experienced a series of ever-worsening droughts. Rice, traditionally a flooded crop, has come under increasing scrutiny with respect to its water use, leading to proposals to evaluate alternative irrigation systems. For growers, weed competition is one of the most limiting factors to maintaining high yields, so understanding the shifts among species in weed communities under the proposed alternative irrigation systems is vital. A field study was conducted from 2012 to 2014 to compare weed population and growth dynamics with three irrigation systems: (1) a conventional water-seeded control system (WS-Control), with a permanent flood of 10 to 15 cm from planting until 1 mo prior to harvest; (2) a water-seeded alternate wet and dry system (WS-AWD), with the field flooded from planting until canopy closure, after which floodwater was allowed to subside and the field was reflooded when the soil volumetric water content reached 35%; and (3) a drill-seeded alternate wet and dry system (DS-AWD), with rice drill seeded and then flush irrigated to establish the crop, after which the field was flooded until canopy closure and then underwent an alternate wet and dry (AWD) treatment similar to WS-AWD. In the AWD treatments, there were two drying periods, neither of which occurred after the heading stage. The dynamics of major weed species were evaluated using plant density counts (2012) and relative cover and biomass (2013 and 2014). Grasses (sprangletop and watergrass species) dominated the DS-AWD system; sedges, broadleaves, and grasses dominated both WS systems. The WS-AWD system increased smallflower umbrella sedge relative cover at canopy closure, relative dry weight at harvest, and percent frequency when compared with the WS-Control system. Yields did not differ across treatments when weeds were controlled (P>0.05); in the absence of herbicides, yields in the WS-AWD were equivalent to the WS-Control (ranging from 40 to 65% of the herbicide-treated yields) and zero in the DS-AWD due to weed pressure.

The intensification of farming practices has reduced weed infestations, but it has also led to a reduction in weed diversity and changes in species composition. These effects are well described for aboveground flora; however, it is less clear how these effects might be expressed in the soil weed seedbank. We evaluated the effects of different long-term farm management strategies on the weed seedbank abundance, diversity, and community composition in the DOK (bioDynamic, bioOrganic, and Konventionell) field trial established in 1978 at Therwil, Switzerland. The trial compares biodynamic, organic, and conventional farming systems, which mainly differ in fertilization, weed control strategies, and pest control. The species richness and seed abundance of the weed seedbank were higher in the organic and biodynamic systems compared with the conventional ones. The different farming systems favored shifts in species assemblages, because specific management practices, such as herbicide application and type of fertilization, acted as filters that selected against certain species but promoted others that were more adapted.
Organic-polymeric radial flow biorreactor for liver models
Authors:   , Ramírez-Fernández O.
Published: July 2016

An artificial liver support system is based on the functional hepatocytes being cultured inside a bioreactor; this technique has been used as an effective therapy for treating chronic liver diseases in recent times. This work evaluates different parameters such as cell viability and metabolic function of the hepatocytes when cultured on a hybrid scaffold. The scaffold was built using a polypyrrole plasma coated polymer layer seeded with endothelial matrix for efficient three-dimensional hepatocyte growth within a radial flow bioreactor. The flow rate inside the bioreactor was 7 ml / min. The parts for the bioreactor were either built using food-grade steel and/or glass or the scaffolds comprise a Poly (L-lactic acid)-coated polypyrrole iodine layer or not for HepG2 culture. The results show that the Poly (L-lactic acid)-coated scaffolds increased cell proliferation by 30%, protein production by 16% and albumin secretion by 40% compared with the non-coated scaffold. All experiments were performed thrice and data were analyzed by ANOVA and Tukey statistic models with a p<0.05. The obtained results demonstrated that radial flow bioreactors in conjunction with hybrid scaffolds improve hepatocytes’ physiological and functional properties and could be used as an alternative therapy for patients with liver diseases.
Manipulation of chirurgical robot by means of a natural interface

Published: July 2016

This paper presents the implementation of a virtual surgical simulator governed by the natural interface through Leap Motion to determine the feasibility of using this interface in this area. The simulator comprises three robots one of which handles the endoscope into the patient’s abdomen, and the others are surgical robots. A method of laparoscopic cholecystectomy (removal of the gallbladder) was developed, which targets through a joystick or natural interface. The application allows some actions such as opening or closing crow bill, locate clips, make cuts and guide the instruments. Additionally, this tool was tested by surgery students, obtaining a better degree of satisfaction with the use of a natural interface.

Konventionelle Behandlungsmethoden von Herz-Kreislauf-Erkrankungen mit synthetischen Gefäßprothesen können aufgrund der eingeschränkten Hämokompatibilität und Einsatzdauer sowie einer mangelhaften biomechanischen Verträglichkeit zu Folgekomplikationen führen. Demgegenüber stellen patientenspezifische textilverstärkte biohybride Gefäßprothesen wegen ihrer hohen Biokompatibilität eine vielversprechende Behandlungsalternative dar. Um eine standardisierte und reproduzierbare Qualität der biohybriden Prothesen sicherzustellen, wird am Werkzeugmaschinenlabor WZL der RWTH Aachen in Zusammenarbeit mit dem Institut für Angewandte Medizintechnik AME der RWTH Aachen ein Anlagenkonzept zur automatisierten, produktzentrierten Herstellung von patientenspezifischen Gefäßprothesen entwickelt. Dabei stehen insbesondere die Anforderungen zur Umsetzung individueller Kultivierungsverläufe und Produktionsparameter für jede zu produzierende Prothese im Vordergrund. Durch die Integration des biologischen Herstellungsprozesses, der notwendigen Aktorik und Sensorik sowie einer lokalen Steuerung auf einer standardisierten Plattform (Mini-Bioreaktor) soll der Kultivierungs- und Konditionierungsprozess einer Gefäßprothese gekapselt ablaufen können.

Age and Group-driven Pedestrian Behaviour: from Observations to Simulations
Authors: Gorrini Andrea , Vizzari Giuseppe , Bandini Stefania
Published: July 2016

The development of pedestrian simulation systems requires the acquisition of empirical evidences about human behaviour for sake of model validation. In this framework, the paper presents the results of an on field observation of pedestrian behaviour in an urban crowded walkway. The research was aimed at testing the potentially combined effect of ageing and grouping on speed and proxemic behaviour. In particular, we focused on dyads, as the most frequent type of groups in the observed scenario. Results showed that in situation of irregular flows elderly pedestrians walked the 40% slower than adults, due to locomotion skill decline. Dyads walked the 30% slower than singles, due to the need to maintain spatial cohesion to communicate (proxemics). Results contributed to refine the parametric validation of the agent-based simulation system ELIAS38.

Authors: Gohr Cláudia Fabiana , Santos Luciano Costa , De Medeiros Rodrigo Araújo
Published: July 2016

A visão baseada em recursos (VBR) representa uma das teorias mais importantes da área de estratégia. De acordo com a VBR, o desempenho econômico superior de uma empresa pode ser sustentado ao longo do tempo quando ela possui recursos que atendem aos critérios definidos pelo modelo VRIO (valiosos, raros, difíceis de serem copiados e organizados pela empresa). Este artigo tem como objetivo verificar se os recursos de uma empresa que atua no varejo de livros podem contribuir para a implementação de estratégias que permitam o desenvolvimento de vantagens competitivas. Para coletar os dados foram utilizados: entrevista semiestruturada, análise de documentos e observação passiva. Os resultados demonstraram que os recursos mais expressivos são os intangíveis, pois contribuem para grande parte das estratégias formuladas, portanto, podem alavancar a vantagem competitiva. Uma versão preliminar deste trabalho foi publicada nos Anais do Simpósio de Engenharia de Produção (SIMPEP), no ano de 2012.
