Light spectrum optimization for plant growth using biological feedback
Authors: Ahlman Linnéa , Bånkestad Daniel , Wik Torsten 
Published: May 2018

The use of light emitting diods (LEDs) as greenhouse illumination is increasingly common. When each LED color is individually dimmable both light spectrum and light intensity can be tuned, which opens up for optimisation of photosynthesis through automatic control of light quality and quantity. However, this requires a non-destructive biological growth signal that can be measured fast, remotely and preferably without interacting with the plants. A potential candidate signal is steady-state chlorophyll a fluorescence gain at 740 nm, defined as dF740/dq, i.e. the difference in fluorescence at 740 nm divided by the difference in incident light quanta caused by a (small) change in intensity of each individual LED color in the lamp (Ahlman et al., 2017). By automatically adjusting the spectrum, to aim for equal fluorescence gains for all LED colors (Wik et al., 2014), the instant photosynthetic rate can be optimised given a preset electric power input to the lamp. When implementing such a controller though, constraints on the&nbsp;spectral distribution are needed to minimise a negative impact on plant morphology.In this study measurements were conducted (on cucumber and lettuce) under different background light, and at each setting excitation signals were sequentially added by each of six different LED colors (peak wavelength at 400, 420, 450, 530, 630 and 660 nm). The corresponding changes in steady-state fluorescence were measured with a spectrometer and the fluorescence gain (dF740/dq) was calculated for each LED color and at each background light setting. These fluorescence gains were compared in order to evaluate the different LEDs' relative effect on photosynthesis under each of the different background light settings.

Published: May 2018

The objective of this study was to examine the psychological factors related to acceptance of disability and to compare the correlated factors with duration of spinal cord injury (SCI). Demographic data, the Acceptance of Disability Scale, the Hospital Anxiety and Depression Scale and the General Perceived Self-Efficacy Scale were analyzed to assess correlation with acceptance of disability of SCI persons attending the outpatient Clinic or admitted to the Rehabilitation Ward, Maharaj Nakorn Chiang Mai Hospital, Chiang Mai between April and May 2004.Sixty-one SCI persons had completed a self-report measure with mean age of 36.6 years and mean duration after SCI of 48.5 months. They were divided into 2 groups-those with injury more than 6 months and those within last 6 months after injury, and were compared in regard to acceptance of disability. Self-efficacy had positive correlation while depression and anxiety were negatively correlated with acceptance of disability (r=.511, -.488,-.456, p<0.01). Sex, educational level, status, severity, duration after SCI and age had no significant correlation with acceptance of disability. In addition, SCI persons who had duration after SCI of more than 6 months reported more acceptance of disability than those being SCI for less than 6 months, though not to the point of reaching the statistical significance.In conclusion, this study shows that self-efficacy and emotional status are correlated with acceptance of disability. SCI persons will be able to adjust to their disability more easily if social learning and emotional support are emphasized. Nepal Journal of Neuroscience, Volume 2, Number 1, 2005, Page: 67-70

Authors: Burhanuddin Dede 
Published: May 2018

This research discusses religious inscription found on the cemetery site in Kota Tinggi Siak Riau Province. The background of this research is based on the changes in the Malay tradition of Islam. Nuanced religious buildings (material culture) such as mosques, tombs and other buildings have undergone substantial changes, some even total changes, one of which is the replacement of Arabic calligraphy in the mosque or cemeteries with new ones. Whereas, before, it is the pride of the people about their Islamic tradition in the past.
Many things become historical documents of development, social, cultural and community traditions in Siak. Inscriptions in the environment Kota Tinggi Cemetery contains data about the Kings, his royal family and the commanders of Siak Kingdom. This can help in discovering the history of the old Siak Kingdom, both from the genealogy of the Kings, the process of the establishment of the Siak Kingdom, its genealogy, development of the Islamic region and other sources. The inscriptions found in this area reveal the religious traditions of the Siak society at that time. Moreover, it can be used as evidence on the proximity between the Siak Kingdom and the teachings of Islam. Not all of the available contents of the inscriptions can be revealed in this research.
This study uses archaeological research in the form of data collection, both literature data and field data obtained through the method of assessment, survey and related research, data processing techniques classification by type, material, location, dimensions and others. Interpretation or meaning of the data obtained through those stages are then incorporated with data obtained through the help of scientific historical analogies (historical), ethnographic, and experiment. However, given technical limitations, this study will only be analyzed through a historical approach.

Additives Fertigungsverfahren zur Herstellung von Bauteilen mit Eigenschaftsgradienten
Authors: Uhlmann Eckart , Wagner Manfred H. , Gerlitzky Georg 
Published: May 2018

Kurzfassung
Additive Fertigungsverfahren gewannen in der Fertigungs und Produktionstechnik in den vergangenen Jahren immer mehr an Bedeutung. Dies ist vor allem durch die nahezu unbeschränkte Designfreiheit begründet, welche die wirtschaftliche Herstellung komplexer Bauteile ohne den Einsatz von Spezialwerkzeugen ermöglicht [1]. Allerdings stehen dem verbreiteten Einsatz der additiven Fertigungstechnologien in der Serienproduktion noch Probleme wie hohe Produktionskosten, schlechte Oberflächenqualitäten der Bauteile sowie teilweise Unklarheit bezüglich der erreichbaren Materialeigenschaften gegenüber. Zudem wurde bisher unzureichend erforscht, in welchem Maße Eigenschaftsgradienten in additiv gefertigten Bauteilen gezielt einstellbar sind [2]. Dieser Beitrag stellt ein Fertigungsverfahren vor, mit welchem es möglich ist, Bauteile mit Eigenschaftsgradienten herzustellen, wie z. B. variierende Härte. Hierzu wird ein prototypisches Maschinensystem beschrieben, mit dem drei Polymere in verschiedenen Dosierungen ineinander gedruckt werden können, um gezielt unterschiedliche Bauteileigenschaften zu generieren. Anschließend werden verschiedene Testbauteile gefertigt und analysiert.

Published: May 2018

An endophytic fungus Chaetomium cupreum was isolated from the ornamental plant Mussaenda luteola. A known metabolite named resorcinol type of lipid (compound 1) was isolated using column chromatography and structurally elucidated by spectroscopic studies includes UV-Vis, FT-IR, NMR, MS analysis and comparing with the existing data. The compound 1 was evaluated for antimycobacterial potential by microtitre plate alamar blue assay against Mycobacterium tuberculosis H37Rv (ATCC27294). It also estimated for DPPH free radical scavenging and antibacterial (agar well diffusion method) potentials. Compound 1 revealed to have significant inhibition of Mycobacterium with MIC of 6.3 µg/mL which is similar to the standard streptomycin drug. It also exhibited good DPPH free radical scavenging potential of 84.5 ± 0.4% and maximum inhibition of both E. coli (ATCC 25922) as well as S. aureus (ATCC 25923). Thus, endophytic fungus C. cupreum from Mussaenda luteola could be a potential source of novel lead antimicrobial agents for drug discovery.

Published: May 2018

New bioactive natural products, the phenolic composition and the biological activities of organic extracts from the needles of the Algerian Pinus coulteri were investigated. The analysis by HPLC-DAD of crude extract revealed the presence of 10 phenolic acids and nine flavonoids. In vitro anti-oxidant activities were performed using four different tests. The greatest antiradical activity was found in the ethyl acetate fraction (IC50 = 3.2 ± 0.3 µg/mL), whereas the diethyl ether fraction had the higher contents of total phenolics and flavonoids and exhibited a highest activity in reducing power and β-carotene–linoleic acid tests with EC50= 67.1 ± 0.4 μg/mL and 71.5 ± 0.2% of inhibition, respectively. Furthermore, a low to moderate antimicrobial activity according to all extracts was revealed against eight bacteria tested. The MIC value of chloroform fraction showed a strong degree of antibacterial activity (<0.09 mg/mL). The crude extract was found toxic with LC50 value of 15.2 μg/mL by brine shrimp toxicity assay. The needle extract of P. coulteri is rich in valuable biologically active compounds and could represent a new resource of anti-oxidant agents for the treatment of diseases.

Numerical Analysis of Consensus Measures within Groups
Authors: Lin Jun-Lin 
Published: May 2018

Measuring the consensus for a group of ordinal-type responses is of practical importance in decision making. Many consensus measures appear in the literature, but they sometimes provide inconsistent results. Therefore, it is crucial to compare these consensus measures, and analyze their relationships. In this study, we targeted five consensus measures: Φ e (from entropy), Φ 1 (from absolute deviation), Φ 2 (from variance), Φ 3 (from skewness), and Φ m v (from conditional probability). We generated 316,251 probability distributions, and analyzed the relationships among their consensus values. Our results showed that Φ 1 , Φ e , Φ 2 , and Φ 3 tended to provide consistent results, and the ordering Φ 1 ≤ Φ e ≤ Φ 2 ≤ Φ 3 held at a high probability. Although Φ m v had a positive correlation with Φ 1 , Φ e , Φ 2 , and Φ 3 , it had a much lower tolerance for even a small proportion of extreme opposite opinions than Φ 1 , Φ e , Φ 2 , and Φ 3 did.
