B.C. Russell, 23 February 1983, 1 (NTM W19003). Description. Complete specimens with 50–81 chaetigers, body 6.2–27.3 mm long and 0.6–1.4 mm wide; cream yellow to reddish brown in alcohol. Incomplete specimens with 29–33 chaetigers, posterior end missing, remaining body 9.5–15.0 mm long and 1.1–1.4 mm wide; cream yellow in alcohol. Prostomium as long as wide. Eyes black, two pairs, outer eyes slightly larger than inner ones, in rectangular arrangement. Palps one pair, palpophores globose, palpostyles conical. Antennae one pair, extend to level of palps. Tentacular cirri four pairs with basal articulation, longest one extending to chaetiger 5–11. Pharyngeal jaws translucent reddish black, curved at tips, with eight teeth on each jaw. Paragnaths reddish black, pectinate bars, present on maxillary and oral rings, arranged as follows: Area I= 0, Area II= 0, Area III= 7 patches in two rows at lateral and three rows in central, Area IV= four curved rows, lateral ones shorter, Area V= 0, Area VI= one slightly curved row, Areas VII–VIII= 5 patches in one row (Fig. 16A–B). Apodous segment as long as first chaetiger. First two chaetigers uniramous. Notopodia present with conical dorsal and ventral ligules in anterior chaetigers, and those ligules become digitiform in posterior chaetigers. Dorsal cirri cirriform, attached on middle of dorsal parapodia, about twice longer than dorsal ligules. Neuropodia with conical ventral ligules, acicular ligules, and triangular postchaetal lobes extending to same level of acicular ligule tips; ventral ligules become digitiform in posterior chaetigers. Ventral cirri cirriform, attached basally on ventral parapodia, slightly shorter than ventral ligules (Fig. 16C). Notochaetae present with homogomph spinigers in first three chaetigers, homogomph spinigers (Fig. 16D) and falcigers (Fig. 16E) from chaetiger 4. Notopodial falcigerous blades short, smooth, curved, with a hooked tip connected to blade. Neurochaetae present with homogomph spinigers and heterogomph falcigers in dorsal fascicles, heterogomph spinigers (Fig. 16F) and falcigers (Fig. 16G) in ventral fascicles. All spinigerous blades short, with fine serrations. Neuropodial falcigerous blades medium-sized, with fine serrations. Acicula translucent. Pygidium with anus on dorsal side, anal cirri cirriform, as long as last one chaetiger. Remarks. The present specimens fit the description of the species by Hutchings & Reid (1991). They are also very similar to the comparative specimens from Ashmore Reef, Western Australia (Fig. 20G–H). As mentioned by these authors, the species is distinguishable from other Australian Platynereis by the presence of a single row of long pectinate bars in the oral ring (P. antipoda and P. polyscalma have two rows). Platynereis uniseris is reported by these authors to be widespread in tropical and warm temperate waters of northern Australia; the present record at Three Mile extends slightly the southern limit of this species for Western Australia. Living specimens show pink pigmentation (Glasby 2015). Distribution. Northern Australia: North-West Australia, Northern Territory, Queensland (Table 2). Habitat. Intertidal, subtidal, rocky shores, dead coral substrate (Table 2).Published as part of Hadiyanto, Hadiyanto, 2023, Nereididae (Annelida: Phyllodocida) from intertidal macroalgae in Western Australia, pp. 151-203 in Zootaxa 5239 (2) on pages 180-181, DOI: 10.11646/zootaxa.5239.2.1, http://zenodo.org/record/762412
Bioethanol Production from Iles-Iles (Amorphopallus campanulatus) Flour by Fermentation using Zymomonas mobilis
Full text linkDue to the depletion of fossil oil sources, Indonesia attempts to search new source of bioenergy including bioethanol. One of this sources is Iles-iles tubers (Amorphophallus campanulatus), which is abundantly available in Java Indonesia. The carbohydrate content in Iles-Iles tuber flour was 77% and it can be converted to ethanol by three consecutive steps methods consist of liquefaction-saccharification using α and β-amylase, respectively and then followed by fermentation by using Z. mobilis. The objective of this research was to convert the Iles-iles flour to bioethanol by fermentation process with Z.mobilis. The ethanol production process was studied at various starch concentration 15-30% g/L, Z. mobilis concentration (10-40%) and pH fermentation of (4-6). The result showed that the yield of bioethanol (10.33%) was the highest at 25% starch concentration and 25% of Z.mobilis concentration. The optimum conditions was found at 4.5, 30°C, 10%, 120 h for pH, temperature, Z. mobilis concentration and fermentation time, respectively at which ACT tuber flour produced a maximum ethanol of 10.33 % v/v.Article History: Received November 12nd 2015; Received in revised form January 25th 2016; Accepted January 29th 2016; Available online How to Cite This Article: Kusmiyati , Hadiyanto,H and Kusumadewi, I (2016).

Control Vector Parameterization with Sensitivity Based Refinement Applied to Baking Optimization
Full text linkIn bakery production product quality attributes as crispness, brownness, crumb and water
content are developed by the transformations that occur during baking and which are
initiated by heating. A quality driven procedure requires process optimization to improve
bakery production and to find operational procedures for new products. Control vector
parameterization (CVP) is an effective method for the optimization procedure. However,
for accurate optimization with a large number of parameters (representing the control
vector), CVP optimization takes a long time for computation. In this work, an improved
method for direct dynamic optimization using CVP is presented. The method uses a
sensitivity based step size refinement for the selection of control input parameters. The
optimization starts with a coarse discretization level for the control input in time. In
successive iterations the step size was refined for the parameters for which the performance
index has a sensitivity value above a threshold value. With this selection, optimization is
continued for a selected group of input parameters while the other non sensitive parameters
(below threshold) are kept constant. Increasing the threshold value lowers the computation
time, however the obtained performance index becomes less. A threshold value in the
range of 10-20% of the mean sensitivity satisfies well. The method gives a better solution
for a lower computation effort than single run optimization with a large number of
parameters or refinement procedures without selection
Preparation and Characterization of Anadara Granosa Shells and CaCO3 as Heterogeneous Catalyst for Biodiesel Production
Full text linkNowadays, the use of homogenous catalyst has been gradually reduced for its operational reason. The homogenous catalyst leads in difficulty of separation after the process completed and the life cycle is shorter. Therefore, most of researches are introducing heterogenous catalyst for its substitution. This research was aimed to evaluate the use of shell of Anadara granosa and CaCO3 as source of CaO based catalyst through impregnation method. The preparation of the catalyst was started by decomposition of shells and CaCO3 at temperature of 800 oC for 3 hours, followed by impregnation at 70 oC for 4 hours and then calcined at 800 oC for 2 hours. The CaCO3 based catalyst gained high yield of biodiesel (94%) as compared to Anadara granoasa based catalyst (92%). The reusability study showed that these catalysts could be used until three times recycle with 40-60% yield of biodiesel. The CaO contents of catalyst decreased up to 90% after three times recycles.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
