Agar from Gracilaria lichenoides and Gracilaria confervoides from Ceylon

"Agar-agar" is a name derived from the jelly obtained from certain red algae in Malaya. In Sri Lanka agar is prepared from the red seaweeds Gracilaria confervoides and Gracilaria lichenoides. They are commonly known as Sri Lanka moss and the local names are "kandha parsi or sanchow parsi". The uses of agar are given together with details of the method of extraction of this substance from Gracilaria lichenoides and Gracilaria confervoides.

Bacillus pallidus sp nov., isolated from forest soil

A Gram-positive bacterium, designated strain CW 7(T), was isolated from forest soil in Anhui Province, south-east China. Cells were strictly aerobic, motile with peritrichous flagella and rod-shaped. The strain grew optimally at 30-37 degrees C and pH 7.0-8.0. The major fatty acids of strain CW 7(T) were anteiso-C-15:0, iso-C-15:0 and anteiso-C-17:0. The predominant menaquinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The G + C content of the genomic DNA was 42.3 mol%. Phylogenetic analysis indicated that strain CW 7(T) belonged to a monophyletic cluster within the genus Bacillus and showed 16S rRNA gene sequence similarities of less than 96.5% to recognized species of the genus Bacillus. The results of the polyphasic taxonomic study, including phenotypic, chemotaxonomic and phylogenetic analyses, showed that strain CW 7(T) represents a novel species of the genus Bacillus, for which the name Bacillus pallidus sp. nov. is proposed. The type strain is CW 7(T) (=KCTC 13200(T)=CCTCC AB 207188(T)=LMG 24451(T)).

Pseudomonas duriflava sp nov., isolated from a desert soil

A Gram-negative, rod-shaped, non-motile, non-spore-forming bacterium, designated strain HR2(T) was isolated from a soil sample from the Talklimaken Desert in Xinjiang Province, China. Strain HR2(T) grew optimally at pH 7.0-8.0 and 30-37 degrees C in the presence of 0-1% (w/v) NaCl. An analysis of 16S rRNA gene sequences revealed that strain HR2(T) fell within the radiation of the genus Pseudomonas, the highest level of similarity being found with respect to Pseudomonas luteola IAM 13000(T) (97.5%); the levels of sequence similarity with respect to other recognized Pseudomonas species were < 96.4%. DNA-DNA hybridization showed that the genetic relatedness between strain HR2(T) and P. luteola IAM 13000(T) was 53.2%. The G + C content of the genomic DNA of strain HR2(T) was 55.2 mol%. The major fatty acids were 18: 1, summed feature 3 and 16:0. The hydroxylated fatty acids 10:0 3-OH, 12:0 3-OH and 12:0 2-OH were also present. The data obtained in this polyphasic study indicated that this isolate represents a novel species of the genus Pseudomonas, for which the name Pseudomonas duriflava sp. nov. is proposed, The type strain is HR2(T) (=KCTC 221129(T) =CGMCC 1.6858(T)).

Sphingobacterium siyangense sp nov., isolated from farm soil

The taxonomic position of a novel Gram-negative strain, designated Sy1(T), isolated from a farm-soil sample obtained from Jiangsu Province, PR China, was characterized by using a polyphasic approach. The cells were non-motile, non-spore-forming rods. The organism grew optimally at 30-37 degrees C and at pH 6.0-8.0. Based on 16S rRNA gene sequence analysis, strain Sy1(T) is a member of the genus Sphingobacterium; Sphingobacterium multivorum JCM 21156(T) was the nearest relative (98.5% sequence similarity). The predominant fatty acids of strain Sy1T were isoC15:0 (32.90/o), C16:0 (10.9%) and summed feature 3 (iso-C-15:0 2-OH and/or C-16:1 omega 7c; 24.1%). The DNA G + C content was 38.5 mol%. The low level of DNA-DNA relatedness (2.2 %) to S. multivorum JCM 21156 T in combination with differential morphological and biochemical properties demonstrated that strain SY1(T) (=KCTC 22131(T)= CGMCC 1.6855(T)) should be classified as representing a novel species of the genus Sphingobacterium for which the name Sphingobacterium siyangense sp. nov. is proposed.

Flavobacterium anhuiense sp nov., isolated from field soil

A novel strain, D3(T), isolated from a field-soil sample obtained from Anhui Province, PR China, was characterized taxonomically by using a polyphasic approach. The cells were Gram-negative, yellow-pigmented rods devoid of flagella, but showing gliding motility. The organism was able to grow at 5-37 degrees C and at pH 4.0-10.0. A comparative 16S rRNA gene sequence analysis indicated that strain D3(T) is a member of the genus Flavobacterium, sharing highest sequence similarity with the type strain of Flavobacterium defluvii (96.7 %). The major isoprenoid quinone was MK-6 and the predominant fatty acids were iso-C-15:0, summed feature 3 (C-16:1 omega 7c and/or iso-C-15:0 2-OH) and C-16:0. The DNA G + C content was 31.4 mol%. On the basis of phylogenetic and phenotypic data, strain D3(T) represents a novel species within the genus Flavobacterium, for which the name Flavobacterium anhuiense sp. nov. is proposed. The type strain is D3(T) (=KCTC 22128(T)= CGIVICC 1.6859(T)).

The WISH pond: potential for development of aquaculture in northeast Cambodia

In Cambodia, fish provide a major source of animal protein for rural households. Capture fisheries have declined and aquaculture has been identified as playing an important role in food and nutritional security and rural income generation. In 2011, WorldFish, in partnership with the Stung Treng Fishery Administration Cantonment and the Culture and Environment Preservation Association, aimed at improving the uptake of small-scale aquaculture by communities with limited experience in fish culture in Stung Treng Province in northeast Cambodia. The system was given the name “WISH ponds,” derived from the combination of the words "water" and "fish" to reflect the integration of fish cultivation with water for storage and vegetable growing. It was targeted towards households with limited space to construct large aquaculture ponds, such as peri-urban households. The study indicated that WISH ponds can create an important learning platform for communities to address challenges associated with small-scale aquaculture development by using scientific data generated and owned by the participants. Results from this 2011 study provided important insights into the challenges and constraints for introducing small-scale aquaculture into rural households in Cambodia. In mid-2013, WorldFish won a Feed the Future Partnering for Innovation grant, funded by the United States Agency for International Development, to build upon its successful engagement with communities in northeast Cambodia where WISH ponds had already been introduced and investigate scaling this technology to establish more WISH ponds in these communities.

The biology, ecology and the fishery of Mukene, Rastrineobola argentea in Lakes Victoria, Kyoga and Nabugabo

Rastrineobola argentea, local name.s Mukene (Uganda) Omena (Kenya) and Dagaa (Tanzania) occurs in lakes Victoria, Kyoga and Nabugabo (Greenwood 1966). Until the decline of the native fishes especially the haplochromines, R. argentea was of little economic importance to the fisheries of these lakes. The stocks of this species have now increased and commercial catches on Lake Victoria account for over 30%. Fishing for R. argentea is currently still restricted to inshore areas and within the fringing islands of Lake Victoria. This fishery is not yet established on Lakes Kyoga and Nabugabo although the species is quite abundant in these lakes (Proude 1963). On moonless nights, kerosene pressure lamps are exposed on the lake to attract the fishes. These fishes are then fished out using fine meshed seine, lampara or lift nets

El plancton de Mar del Plata durante el período 1961-1962 (Buenos Aires, Argentina)

The first part presents a general picture of the composition of the coastal plankton near Mar del Plata (Buenos Aires prov., Argentina) between August 1961-August 1962. Especially noted is the abundance of Noctiluca from October to the end of March. The second part deals with the plankton collected during a short cruise, named Operación Mar del Plata 1, planned to survey coastal waters. In the third part the author gives the descriptions of some new or interesting species. A chain-forming Gymnodinium is reported as G. catenatum; some differences with Graham description, could be due to the fact that he studied only preserved material. Oblea baculifera is a new species belonging to the new genus Oblea, of the Diplopsalis group, created for some species previ¬ously known as Peridiniopsis. A key of the included species is given. The other new species are Peridinium aspidiotum, P. anomaloplaxum, P. lipopodium and Gonyaulax fratercula, all of them carefully described and depicted. Sticholonche zanclea (Radiolaria), Calsiosolenia sinuosa (Coccolithophoridae) and Tintinnopsis levigata (Tintinnida) are reported for the first time in the South-Atlantic. For T. levigata ?, Balech, 1939, a new name has been created: T. tregouboffi. Some unknown details of the protoplasm of the silicoflagellate Dictyocha octonaria are described. In the fourth part the author compares the plankton taken in Mar del Plata with the previously studied at Pto. Quequén. The plankton of March-April points to an invasion of oceanic warm waters from the Brazilian Current System.

Meiothermus rosaceus sp nov isolated from Tengchong hot spring in Yunnan, China

A rosy-pigmented Gram-negative, thermophilic bacterium with an optimum growth temperature of about 55degreesC was isolated from Tengchong hot springs in Yunnan province, China. Its growth scarcely occurred below 40degreesC or above 70degreesC. Phylogenetic and secondary structural analyses of 16S rRNA and DNA-DNA hybridization showed that the organism represented a new species of the genus Meiothermus. This new species could be distinguished easily from other species of the genus Meiothermus by the following phenotypic characteristics: rosy pigment, expanded body, sucrose and maltose were not utilized, gelatin and starch were not hydrolyzed. On the basis of the above data, the name Meiothermus rosaceus sp. nov. was proposed for the species represented by the strain RH9901(T)(CCTCC-AB200291).

Thermus rehai sp nov., isolated from Rehai of Tengchong, Yunnan Province, China

A yellow-pigmented strain of the genus Thermus, with optimum growth temperatures about 65-70 degreesC, was isolated from the hot springs in Rehai of Tengchong, Yunnan Province, China. Morphological, physiological and biochemical characteristics, pigment analysis of RH99-GF7504 strain and its phylogenetic analysis of 16S rDNA showed that this organism represented a new species of the genus Thermus(1)). This strain had maximum temperatures for growth below 80 degreesC. The new isolate from Rehai of Tengchong could be distinguished from other strains of the genus Thermus by its special structure and by its inability to hydrolyze gelatin and starch. On the basis of phylogenetic analysis, morphological, physiological and biochemical characteristics, the name Thermus rehai sp nov is proposed for the species, represented by strain RH99-GF7504 (CCTCC-AB200292).

Channel-hopping model predictive control

In Multiplexed MPC, the control variables of a MIMO plant are moved asynchronously, following a pre-planned periodic sequence. The advantage of Multiplexed MPC lies in its reduced computational complexity, leading to faster response to disturbances, which may result in improved performance, despite finding sub-optimal solution to the original problem. This paper extends the original Multiplexed MPC in a way such that the control inputs are no longer restricted to a pre-planned periodic sequence. Instead, the most appropriate control input channel would be optimised and selected to counter the disturbances, hence the name 'Channel-Hopping'. In addition, the proposed algorithm is suitable for execution on modern computing platforms such as FPGA or GPU, exploits multi-core, parallel and pipeline computing techniques. The algorithm for the proposed Channel-hopping MPC (CH-MPC) will be described and its stability established. Illustrative examples are given to demonstrate the behaviour of the proposed Channel-Hopping MPC algorithm. © 2011 IFAC.

Fatigue life and self-induced volumetric changes of CARDIFRC

A class of ultra-high-performance fibre-reinforced cementitious composites (UHPFRCC) has been developed at Cardiff university and registered under the trade name CARDIFRC. The method of its production and its mechanical and fracture properties were reported previously in a series of papers in Magazine of Concrete Research. Here the results of recent fatigue and shrinkage tests on this material are reported. As with the mechanical and fracture properties, it is shown that an even and uniform distribution of fibres throughout the bulk of the material is crucial to its superior fatigue performance and to the reduction in the shrinkage strains. © 2010 Thomas Telford Ltd.
