Development of a remotely activated field sprayer and evaluation of temperature and aeration on the longevity of Steinernema riobrave entomopathogenic nematodes for treatment of cattle fever tick-infested nilgai

A remotely activated field sprayer was developed for application of the entomopathogenic nematode, Steinernema riobrave (Cabanillas, Poinar, and Raulston) for eradication of the southern cattle fever tick, Rhipicephalus microplus (Canestrini) infesting free-ranging nilgai (Boselaphus tragocamelus) in South Texas. The battery powered sprayer is activated by sonic sensors that detect movement of nilgai through fence crossings. An onboard computer operates the sprayer pump and aerator that oxygenates the solution of nematodes. Several types of aeriation, agitation, and cooling were tested to prolong the viability of the nematodes in water. Continuous aeration extended the longevity of S. riobrave to more than two weeks as compared to cooling or intermittent agitation. The potential use of nematodes pathogenic to R. microplus dispensed by the remotely activated sprayer to infested nilgai, and potentially white-tailed deer (Odocoileus virginianus), as part of integrated cattle fever tick eradication efforts is discussed.

Cross-Hedging Ambiguous Exchange Rate Risk

This paper examines the behavior of an exporting firm that sells its output to two foreign countries, only one of which has futures and options available for its currency. The firm possesses smooth ambiguity preferences and faces multiple sources of ambiguous exchange rate risk. We show that the separation theorem fails to hold in that the firm’s production and export decisions depend on the firm’s attitude towards ambiguity and on the incident to the underlying ambiguity. Given that the random spot exchange rates are first-order independent with respect to each plausible subjective distribution, we derive necessary and sufficient conditions under which the full-hedging theorem applies to the firm’s cross-hedging decisions. When these conditions are violated, we show that the firm includes options in its optimal hedge position. This paper as such offers a rationale for the hedging role of options under smooth ambiguity preferences and cross-hedging of ambiguous exchange rate risk.
Stable Transformation of Cyanobacterium Synechocystis sp.

[Abstract] Cyanobacteria are prokaryotes, which perform oxygenic photosynthesis. Among them, the unicellular cyanobacterium Synechocystis sp. PCC 6803 (hereafter Synechocystis) is a well characterized model system for studies on oxygenic photosynthesis, light signal transduction etc. Moreover, Synechocystis is applied in biotechnological applications (Desai and Atsumi, 2013). Stable transformation of Synechocytis is achieved via the uptake of DNA and incorporation into the host genome by homologous double recombination. This allows for the generation of gene knock-outs (KO) by replacing the coding sequence of the gene of interest by a KO-cassette (comprising of a selection marker flaked by sequences of the gene of interest) or stable overexpression of certain genes of interest after insertion of a corresponding overexpression cassette at a neutral insertion site on the host genome. Stable transformation of Synechocystis was reported by Grigorieva and Shestakov (1982). Since then, variants of the initial protocol have been applied successfully to transform Synechocystis sp. Here we describe a lab-protocol that was applied successfully for stable transformation of Synechocystis (Schwarzkopf et al., 2014).
Heterobasidion dsRNA viruses: diversity, taxonomy and effects

Species of the Heterobasidion annosum sensu lato (s. l.) complex are causing root and butt rot of conifers. Mycoviruses are usually cryptic, but some of them may cause hypovirulence (reduced virulence) or mutualistic effects on their fungal hosts. We explored new Heterobasidion viruses, and analyzed their taxonomy and effects on their hosts. The viruses were obtained from fungal culture collection of the Natural Resources Institute Finland (Luke) or from newly collected isolates. This thesis addressed the taxonomy of Heterobasidion viruses as well as their transmission, effects on hosts’ phenotypes, and distribution. A new dsRNA virus from H. annosum s.s. , Heterobasidion RNA virus 6 (HetRV6), was found taxonomically distant from all previously known viruses of Heterobasidion spp. , but related to the mutualistic Curvularia thermal tolerance virus. Populations of this species exhibited a considerable degree of geographical and host-related differentiation. Virus isolates HetRV6-ab6 and Heterobasidion partitivirus 3 (strain HetPV3-ec1) conferred different and conditiondependent effects on different host strains. Four new partitivirus species, HetPV12, HetPV13, HetPV14 and HetPV15, clustered in a clade within the genus Alphapartitivirus that includes also HetPV3 and Helicobasidium mompa partitivirus V70. HetPV13 strains were found to have a high dispersal capacity. A high infection rate by four species of partitiviruses was observed in H. annosum in a heavily infected forest. Two of these species were previously unknown (HetPV16 and HetPV20). Three fungal isolates were co-infected by two different partitiviruses (HetPV13-an2 and HetPV7-an1 or HetPV16-an1 and HetPV20-an1), supporting the view that multiple infections are common. Taken together, the global diversity and prevalence of Heterobasidion viruses is considerable, and their transmission may occur between somatically incompatible strains. They may co-infect single host strains, transmit over species borders and confer variable phenotypic effects on their hosts. Further studies are necessary to determine the biocontrol potential of these viruses.
IMPACT OF DIETARY PROTEIN AND AQUA-MAX PLUS® ON GROWTH, FEED EFFICIENCY, AND PHYSIOLOGICAL RESPONSES OF MONO-SEX NILE TILAPIA (Oreochromis niloticus, L. 1758)

This experiment was designed to estimate the effect of different levels of dietary protein with the addition of Aqua-Max Plus® (as a feed additive) on growth performance, feed utilization, the chemical composition of the whole fish body, and physiological responses of mono-sex Nile tilapia, Oreochromis niloticus. Six hundred of mono-sex Nile tilapia fingerlings (at average initial bodyweight 52.64 ± 5.2 g) were distributed randomly to five treatments. Experimental diets contain different levels of dietary crude protein 21, 23, 25, 27% (referred to No. T1, T2, T3, and T4, respectively) and that were compared to the control diet contains 25% without adding Aqua-Max Plus® (T0). Results revealed that the increasing dietary protein in diets leads to an improvement in growth performance and hematological parameters as well as total protein, albumin, and globulin concentrations in blood serum. Fish fed on a diet containing 21% protein (T1) recorded the lowest values of growth performance, feed efficiency, and hematological parameters. The addition of Aqua-Max Plus® to diets containing 23% (T2) and 25% (T3) crude protein enhanced growth performance and feed efficiency parameters compared to the control diet. Protein content was significantly improved, whereas fat, ash and EC contents were reduced by increasing the dietary protein. The addition of Aqua-Max Plus® to the experimental diets had no significant effect on serum biochemical parameters. Finally, the addition of Aqua-Max Plus® in the Nile tilapia diets improve the nutritional values of low protein diets, and it is a way to reduce the cost of fish feed.
IDENTIFICATION OF CYTOGENETICALLY VISIBLE mtDNA IN INTERPHASE NUCLEI OF HUMAN BLOOD LYMPHOCYTES EXPOSED TO DOXORUBICIN

The endosymbiotic hypothesis suggests that mitochondria were free-living organisms that colonized another cells, and millions of years of co-evolution resulted in the transfer of a large number of genes from mitochondria to the nucleus. Recent studies indicate that this is an ongoing process and can be due to the impact of cells to DNA damaging agents, e.g. radiation or chemical mutagens. Here we demonstrate that cytogenetically visible mitochondrial DNA translocation into interphase nuclei genome in human blood lymphocytes can be identified via fluorescence in situ hybridization after exposure of cells to doxorubicin.

Genotyping and Nucleotide Sequences of Growth Hormone Releasing Hormone and Its Receptor Genes in Egyptian Buffalo

Aim: The hypothalamic hormone, growth hormone-releasing hormone, is the principal stimulator of pituitary growth hormone ( GH ) synthesis and secretion. GHRH and its receptor ( GHRHR ) provide important functions in the regulation of the GH axis and in the development and proliferation of pituitary somatotropic axis. This study aimed to identify the genotypes and nucleotide sequences of two multifunctional genes; growth hormone-releasing hormone ( GHRH ) and its receptor ( GHRHR ) in Egyptian buffalo. Methodology: Genomic DNA was extracted from blood samples of 100 healthy buffaloes maintained at the Mahlet Mussa and El-Gmeasa herds from 2010 to 2012. PCR was performed using primers flanking a 296-bp fragment from GHRH gene and a 425-bp fragment from GHRHR gene of Egyptian buffalo. The PCR-amplified fragments were digested with Hae III ( GHRH ) and Original Research Article
Middle school students’ views about leaders and leadership

This article presents the views of 72 Australian middle school students from 12 metropolitan schools across six states and territories as to their understanding of leadership. Initially, literature is reviewed regarding the developments in middle-years education and theories of leadership pertinent to student leadership. The research methodology is then explained, providing an overview of the participants, the school contexts and methods of data collection and analysis. The subsequent section on results is presented under three topics: examples of good leaders, attributes that make a good leader and participants’ understanding of the concept of leadership. A final discussion is centred on three considerations: the form of leadership that middle school students believed to be appropriate, the type of leadership that they rejected and possible underlying reasons for their choices.
mDroid : A Machine Learning Based Malware Identification System For Android

— The explosive growth of smart phones and wide acceptance of android brings a large scope for android mobile malwares. As the number of applications in android platform increases, number of malwares is also increasing rapidly. Since today’s smartphones are a ubiquitous source of confidential datas, hackers are very much interested in targeting mobile phones. So security of mobile phones is a major issue. This paper presents a new machine learning based approach for detecting malwares in the android platform. We perform hybrid analysis over downloaded applications to specify whether it is of malicious behaviour or not.
THE DISTRIBUTION OF WHITE CLOVER (TRIFOLIUM REPENS L.) AND GRASSES WITHIN SIX SOWN HILL SWARDS

potassium. (3) White clover was adversely affected by soil acidity and appeared more sensitive to soil aluminium than the grasses. (4) White clover was usually positively associated with Lolium perenne and negatively with Agrostis tennis Sibth. Lolium perenne was usually positively associated with Poa spp. and negatively with Agrostis tennis. (5) White clover appeared to be reduced by shortage of moisture on relatively shallow soils. (6) Molehills which remained raised were largely colonized by species other than white clover and Lolium perenne. (7) Farmers wishing to encourage white clover should therefore apply sufficient lime, grow the clover with Lolium perenne rather than with Agrostis tennis, choose sufficiently deep soils, and control moles.
Toxicity of the harmful dinoflagellate Cochlodinium polykrikoides to early life stages of three estuarine forage fish

Harmful algal blooms (HABs) caused by the dinoflagellate Cochlodinium poly krikoides have increased in geographic extent, frequency, and duration in coastal areas worldwide. These blooms have negatively impacted many coastal fisheries, causing mass mortalities of both wild and farmed fish. Forage fish species may be particularly susceptible to HABs as they feed on plankton and are highly abundant in coastal ecosystems where these blooms occur. While mortalities associated with HABs have been well documented for juvenile and adult fish, the potential impacts to early life stages (i.e. embryos and eleutheroembryos) have not been explored. We conducted a series of toxicity experiments using a clonal laboratory culture of C. polykrikoides and 3 forage fish species (Atlantic silverside Menidia menidia, inland silverside M. beryllina, and sheepshead minnow Cyprinodon variegatus) all common on the US East Coast. Our experiments demonstrated that C. polykrikoides caused mortalities in both embryos and eleutheroembryos, but that sensitivity to acute toxicity differed among fish species (M. beryllina > M. menidia > C. variegatus) and among life stages (eleutheroembryos > embryos). Although embryos were somewhat resistant to C. polykrikoides biotoxins until they hatched, once they hatched, they experienced rapid mortality and impaired swimming ability. By testing ecologically relevant exposure times to C. polykrikoides, we found that eleutheroembryos can become incapacitated relatively quickly (i.e. within hours), and that surviving fish could recover swimming ability following removal from C. polykrikoides exposure. This research provides the first evidence of sublethal impacts on fish exposed to C. polykrikoides, and advances understanding of the potential ecosystem impacts of this harmful alga.

Experimental and numerical analysis of stick-slip suppression with the use of longitudinal tangential vibration

The results of experimental tests and numerical simulation analyses of the possibility of partial reduction or entire elimination the stick-slip phenomenon in sliding motion through introduction of longitudinal tangential vibrations to the contact zone of a shifted body and the substrate are shown in the paper. The experimental tests were carried out on a specially designed stand. In the computational model, the dynamic equation of motion of the shifted body was used, and for the friction force description the LuGre model was adopted. A excellent consistency of the experimentally determined results with those calculated with the use of the developed model is obtained.
Projection mapping onto multiple objects using a projector robot

Even though the popularity of projection mapping continues to increase and it is being implemented in more and more settings, most current projection mapping systems are limited to special purposes, such as outdoor events, live theater and musical performances. This lack of versatility arises from the large number of projectors needed and their proper calibration. Furthermore, we cannot change the positions and poses of projectors, or their projection targets, after the projectors have been calibrated. To overcome these problems, we propose a projection mapping method using a projector robot that can perform projection mapping in more general or ubiquitous situations, such as shopping malls. We can estimate a projector’s position and pose with the robot’s self-localization sensors, but the accuracy of this approach remains inadequate for projection mapping. Consequently, the proposed method solves this problem by combining self-localization by robot sensors with position and pose estimation of projection targets based on a 3D model. We first obtain the projection target’s 3D model and then use it to accurately estimate the target’s position and pose and thus achieve accurate projection mapping with a projector robot. In addition, our proposed method performs accurate projection mapping even after a projection target has been moved, which often occur in shopping malls. In this paper, we employ Ubiquitous Display (UD), which we are researching as a projector robot, to experimentally evaluate the effectiveness of the proposed method.
Clinical comparison of platelet-rich plasma injection and daily celecoxib administration in the treatment of early knee osteoarthritis: A randomized clinical trial.

BACKGROUND Oral and topical nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics and intra-articular corticosteroid injections are the recommended first line of treatment for knee osteoarthritis (OA); however, they have serious side effects. Platelet-rich plasma (PRP) has been posited as an effective and safer alternative treatment for knee OA. Hitherto, there is only one study comparing the effectiveness of PRP against an NSAID. AIM OF THE STUDY The aim of this study was to determine the effectiveness of PRP against celecoxib in the treatment of early knee OA. METHODS 60 patients with knee OA grade II and III were randomly alocated in two groups. Group 1 received one injection of autologous PRP in each affected knee, with a reinjection after 15 days; Group 2 received 200 mg of oral celecoxib each 24 h for a year. Visual Analogue Scale (VAS), total Western Ontario and McMaster Universities Arthritis Index (WOMAC) and WOMAC subscales for pain, stiffness and function were measured at baseline and at 1, 3, 6 and 12 months after the start of the treatment. RESULTS At the end of the study PRP was significantly better than celecoxib (p < 0.05) in improving VAS (40.40%), total WOMAC (58.95%) and WOMAC subscales of pain (50.60%), stiffness (34.13%) and function (51.90%). Significant differences remained after adjusting for age, sex or knee OA grade II or III. CONCLUSIONS Intra-articular PRP is significantly better than celecoxib in improving pain, function and stiffness in early knee OA. This significant difference is independent of age, sex or knee OA grade II or III.
