MULTIVARIATE SELECTION OF NUTRIENT PARAMETERS IN SUBMERGED CULTURE OF KLUYVEROMYCES MARXIANUS FOR BIOSURFACTANT PRODUCTION

Surfactants are compounds that decrease surface tension and are produced by chemical or biological synthesis. Biosurfactants are produced by the metabolism of microorganisms and have advantages regarding the use of chemicals, mainly due to the low toxicity and biodegradability. Initially a fractional factorial design 2 (6-2) was applied to study the effect and interactions of concentrations of different nutrients on the production of biosurfactants by yeast Kluyveromyces marxianus (CCT-3172). Aliquots of 1% (v/v) of microbial inoculum were transferred to the culture media prepared according to the experimental design and incubated on a shaker table at 200 RPM and with a temperature control at 28ºC±2 for 144 hours. The biosurfactant production was verified by the emulsification index (E 24 ) following the methodology of Cooper and Goldenberg (1987). Based on the experimental results, the yeast K. marxianus (CCT-3172) demonstrated potential for biosurfactant production, evidenced by the emulsifying index in fermentation medium. With the application of factorial design, it was concluded that to maximize the biosurfactant production process, the ammonium sulfate and glycerol must be absent from the fermentation medium to eliminate its negative effects in the process. In a next step, the objective is to apply the response surface methodology to optimize biosurfactant production.
TUDI DAYA DUKUNG SUMBER DAYA IKAN DI WADUK JATIBARANG SEMARANG

Waduk Jatibarang merupakan waduk yang belum lama beroperasi dan masih tergolong waduk baru. Kegiatan perikanan yang berkembang didominasi oleh perikanan pancing. Selain penangkapan, peningkatan produksi juga dilakukan dengan penebaran ikan, namun belum didukung kajian daya dukung yang memadai. Penelitian ini dilakukan untuk mengetahui nilai daya dukung sumber daya ikan di waduk Jatibarang. Kegiatan penelitian dilakukan pada Bulan Mei dan Juli 2018 yang meliputi 4 (empat stasiun yang mewakili inlet, tengah dan outlet waduk. Data primer yang dikumpulkan meliputi kualitas air (parameter fisika, kimia dan biologi). Data pendukung penelitian meliputi elevasi muka air, diperoleh dari Balai Besar Wilayah Sungai Pemali-Juana, dan data kedalaman, diperoleh dari akuisisi data GPS Sounder. Hasil penelitian menunjukkan bahwa nilai daya dukung sumber daya ikan di Waduk Jatibarang berkisar antara 3,57-6,3 ton/tahun. Kedalaman perairan sangat mempengaruhi nilai daya dukung. Nilai daya dukung lebih rendah pada kedalaman perairan lebih dari 20 m dan relatif tinggi pada kedalaman lebih dari 10 m. Selain pengaruh kedalaman juga terdapat pengaruh lain seperti fluktuasi muka air, kelimpahan plankton, kecerahan, dan unsur hara berupa nitrat. Diharapkan kajian terkait potensi produksi dapat dilakukan untuk optimalisasi pemanfaatan perikanan yang berkelanjutan. Jatibarang Reservoir is a new operating reservoir. Existing fishing activities are dominated by handline. Except fishing activities, many fish have been stocked to improve the production, but it has not been supported by adequate carrying capacity studies. The purpose of this research was to determine the value of carrying capacity of fish resources in the Jatibarang Reservoir. The study was conducted in May and July 2018 representing the inlet, center, and outlet of the reservoir. The collected data consisted of physical, chemical, and biological data obtained at 4 (four) research stations representing the inlet, center, and outlet of the reservoir. Supporting data include water level elevation obtained from the Pemali-Juana River Basin Authority and bathymetry data obtained from GPS Sounder data acquisition. The results showed that the value of carrying capacity of fish resources in the Jatibarang Reservoir is 3.57-6.3 tons/year. The depth of the waters greatly affects the value of carrying capacity. The value of smaller carrying capacity occurs at the water depths of more than 20 m, but is relatively high at the depths of more than 10 m. There are also other influences such as water level fluctuations, plankton abundance, water brightness, and nitrates. Furthermore, a study of production potential should be carried out to optimize the sustainable fisheries utilization.
Effect of environmental corporate social responsibility on green attitude and norm activation process for sustainable consumption: Airline versus restaurant

The major aim of this research was to develop theoretical frameworks clearly explicating airline and restaurant customers' decision formation for eco-friendly products. Using a quantitative approach, we successfully broadened the norm activation theory by integrating environmental corporate social responsibility (CSR) and attitude toward the behavior. In addition, the theory was effectively deepened by taking the influence of product type (airline vs. restaurant) into account. The developed conceptual frameworks satisfactorily explained the variance in eco-friendly purchase intention for airline products and for restaurant products, respectively. The mediating effect of attitude, ascribed responsibility, and personal moral norm was uncovered. Additionally, a salient contribution of attitude toward eco-friendly product use in inducing intention for both airline and restaurant groups was found.
Three-Dimensionally Engineered Normal Human Lung Tissue-Like Assemblies: Target Tissues for Human Respiratory Viral Infections

In vitro three-dimensional (3D) human lung epithelio-mesenchymal tissue-like assemblies (3D hLEM TLAs) from this point forward referred to as TLAs were engineered in Rotating Wall Vessel (RWV) technology to mimic the characteristics of in vivo tissues thus providing a tool to study human respiratory viruses and host cell interactions. The TLAs were bioengineered onto collagen-coated cyclodextran microcarriers using primary human mesenchymal bronchial-tracheal cells (HBTC) as the foundation matrix and an adult human bronchial epithelial immortalized cell line (BEAS-2B) as the overlying component. The resulting TLAs share significant characteristics with in vivo human respiratory epithelium including polarization, tight junctions, desmosomes, and microvilli. The presence of tissue-like differentiation markers including villin, keratins, and specific lung epithelium markers, as well as the production of tissue mucin, further confirm these TLAs differentiated into tissues functionally similar to in vivo tissues. Increasing virus titers for human respiratory syncytial virus (wtRSVA2) and the detection of membrane bound glycoproteins over time confirm productive infection with the virus. Therefore, we assert TLAs mimic aspects of the human respiratory epithelium and provide a unique capability to study the interactions of respiratory viruses and their primary target tissue independent of the host s immune system.
Dickdellia on Colossendeis: testing ectoparasitism with stable isotopes

Many pycnogonids are ectoparasites of benthic invertebrates. Even gastropods are on their menu (reviewed in Dietz et al. 2018). It is somewhat ironic that a marine gastropod, Dickdellia labioflecta (Dell, 1990), might have reversed this principle. Hedgpeth (1964), Sirenko (2000) and Schiaparelli et al. (2008) observed clutches of eggs and young Dickdellia snails on pycnogonids. Sirenko (2000) suggested that this might be a case of ectoparasitism and not just phoresy.
Copula function-based analysis of outage probability and coverage region for wireless multiple access communications with correlated fading channels

From practical and theoretical viewpoints, performance analysis of communications with correlated fading channels is important. In this study, the authors exploit a novel approach based on Copula function concept to investigate the impact of correlation of Rayleigh fading channels on communication performances. One of the most convenient ways to describe the dependence between several variables is using Copula functions. For this purpose, by applying the Farlie–Gumbel–Morgenstern Copula function, they derive closed-form expressions for outage probability as well as coverage region in a wireless multiple access channel. It is shown that the fading correlation improves the outage probability and coverage region for negative dependence structure. Specifically, whenever the dependence structure tends to negative values, the outage and coverage region performance improvement is increased. Finally, the efficiency of the analytical results is illustrated numerically.
Liquidity and Corporate Governance

This paper discusses the relationship between stock market liquidity and corporate governance. Both concepts are widely investigated from different angles in the literature. It is generally agreed that they are related so that better corporate governance implies higher liquidity for shares of listed companies. However, the importance of good corporate governance for the market liquidity of the share will differ depending on the characteristics of the firm’s business. Good corporate governance will be particularly important in reducing agency problems in firms where the business is subject to a high degree of uncertainty. Proper corporate governance, in other words, matters most for firms where external assessment of the firm’s business prospects is difficult, while it is less important for value creation in firms where the business is easier to understand.

En outre, la consistance forte et la normalite asymptotique de l'estimateur des poids et des biais des RN considere sont garanties sous de faibles conditions.
Diet overlap and habitat utilization of rainbow trout and juvenile walleye in Cooney Reservoir, Montana

Diet overlap and habitat utilization were compared for rainbow trout (Oncorhynchus mykiss) and juvenile walleye (Stizostedion vitrevm) in Cooney Reservoir, Montana for the period between May and October, 1992. Additionally, walleye spawning activity was monitored in the reservoir and tributary creeks during April and May, 1993. Diet and habitat samples were taken twice monthly along randomly-selected 200 m transects over the three available substrates. Zooplankton tows were taken along the same transects 24 hours prior to fish sampling. Gastric lavage was used to remove stomach contents, and all fish were released. The proportion of fish collected over each substrate provided an estimate of habitat utilization. Rainbow trout were randomly distributed during all sampling periods, and fed almost exclusively on zooplankton. Juvenile walleye selected for sand substrate and against the dam face through July, after which they were randomly distributed. Chironomids were the primary prey for juvenile walleye through June, but thereafter crayfish, fish, mayflies (Callibaetis spp.) and zooplankton dominated their diet. Diet overlap was not significant between the two. Walleye spawned in Red Lodge Creek, and several young-of-the-year walleye were collected from the reservoir. Apparent lack of natural walleye recruitment is hypothesized to be a result of a scarcity of copepods in the reservoir when walleye fry begin to feed.

Exactly true and non-falsity logics meeting infectious ones

In this paper, we study logical systems which represent entailment relations of two kinds. We extend the approach of finding ‘exactly true’ and ‘non-falsity’ versions of four-valued logics that emerged in series of recent works [Pietz & Rivieccio (2013). Nothing but the truth. Journal of Philosophical Logic, 42(1), 125–135; Shramko (2019). Dual-Belnap logic and anything but falsehood. Journal of Logics and their Applications, 6, 413–433; Shramko et al. (2017). First-degree entailment and its relatives. Studia Logica, 105(6), 1291–1317] to the case of infectious logics, namely to the case of Deutsch's logic introduced in Deutsch [Relevant analytic entailment. The Relevance Logic Newsletter, 2(1), 26–44; The completeness of S. Studia Logica, 38(2), 137–147]. The particular systems obtained in this way are and . We present them in the form of sequent calculi and prove corresponding soundness and completeness theorems. We illuminate the connection between , and two well-known systems, strong Kleene three-valued logic and Priest's Logic of Paradox . This connection allows us to investigate the characterisation of the entailment relations associated with and as well as to introduce the notion of ‘infectious analogue’ of a certain logic. We also study implicative extensions of and and prove soundness and completeness theorems for them as well.
Selection for behaviour in poultry.

INTRODUCTION Genetic selection for behavioural traits has been carried out traditionally in many domestic animal species before scientific information on the inheritance of traits was available. In some cases the behaviour was the primary purpose for domestication. It is assumed that Japanese quail (Coturnix japonica) has been kept and selected for its song prior to selection for egg and meat production. The crow of roosters was also subject to selection in the past, and some breeds with extended length and frequency of crows are still kept and selected by fancy breeders. First studies using quantitative genetic analysis have been carried out on broodiness in domestic chickens by Saeki (1957). In the 1960`s the social and sexual behaviour was subject to heritability analysis and selection experiments (Guhl et al., 1960; Craig et al., 1965; Siegel, 1965). In the 1970`s and later the welfare discussions raised the questions on adaptability of the animals to intensive husbandry conditions and the behavioural needs of the birds in response to their genetic background. Fear related behaviour, such as tonic immobility, open-field activity, has been studied as a central mechanism to cope with different environmental conditions and unfamiliar stimuli (Jones et al., 1982). The restriction of physical space, lack of litter material and nest boxes in conventional cages has stimulated genetic studies on the locomotor activity, including pre-laying restlessness (Jezierski and Bessei, 1978; Heil, et al., 1990), and dustbathing behaviour (Gerken, 1983). With the development of loose house systems using large group sizes problems of feather pecking and cannibalism have increased, and measures are sought to control the so-called vicious behaviours. Since management measures (except beak trimming) have failed to effectively control the problems caused by feather pecking and cannibalism so far genetic selection has been put forward as a potential means to improve the situation. Fear-related behaviour and adaptability has also to be mentioned in this context. This behavioural complex is dealt with elsewhere in this conference. The following contribution will focus on social behaviour, locomotor activity, dustbathing, and special attention will be paid to feather pecking and cannibalism.
Comparison of routing protocol performance on multimedia services on software defined network

Software defined network (SDN) is a new paradigm in network engineering, where control plane and data plane are separated. Data plane is carried out on each node, while a control plane is centrally located. In conventional networks, the planes are implemented in the firmware of the router. In this paper, we implemented multimedia services on SDN using exterior and interior routing protocols, such as open shortest path first (OSPF), border gateway protocol (BGP) and routing information protocol (RIP), measured the quality of service (QoS), and analyze the measurement results. The test results showed that the greater the background traffic provided, the smaller the throughput. Traffic on the network will be congested, so the available bandwidth is also increasingly used up so that the number of bits sent every second decrease. Mean opinion score (MOS) test results are 4 showing good categories based on ITU-T standards.

Optimal Operation Strategies under a Carbon Cap-and-Trade Mechanism: A Capital-Constrained Supply Chain Incorporating Risk Aversion

Many small and medium enterprises (SMEs) with capital constraints often have no access or find it costly to obtain a loan from a bank; the retailer tends to borrow money from other enterprises in the supply chain by trade credit financing. We consider an emission-dependent supply chain with one emission-dependent manufacturer and one capital-constrained retailer in need of financing to explore the optimal operational and environmental strategies of a low-carbon supply chain under trade credit financing. We use a Stackelberg game model to depict the low-carbon supply chain. We analyse the optimal carbon-emission reduction effort, wholesale price, and order quantity in the equilibrium state. The impacts of key parameters, such as the retailer’s internal working capital, the manufacturer’s risk-aversion degree, and the carbon-trading price on the supply chain operation, are analysed. The results show that the retailer’s capital constraint causes the carbon-emission reduction effort, wholesale price, and order quantity to improve synchronously. The supply chain achieves a win-win outcome for both the manufacturer and the retailer when the capital-constrained retailer is funded via trade credit from the manufacturer. The in-depth development of financing is beneficial to the manufacturer but is a disadvantage for the retailer. When the initial carbon-emission quota is low, the manufacturer benefits from a relatively lower carbon-trading price. Otherwise, a higher carbon-trading price is better for the manufacturer. The “carbon-trading price trap” ensures that the retailer’s profit is minimal. We further investigate the scenario in which the manufacturer is risk averse and find that the retailer will purchase fewer products and that the manufacturer will gain less profit to decrease the carbon-emission reduction effort. The manufacturer’s risk aversion is unfavourable to both the economic and environmental outcomes of the whole supply chain. This research provides strategic support for a low-carbon supply chain to carry out operational decisions in the context of enterprise capital constraint. To examine the theoretical results, the data used in the existing literature are further used to simulate the corresponding conclusions. Our research enriches the existing supply chain finance literature and provides decision support for the supply chain core enterprise.
Immunohistologic demonstration of hepatitis B viral antigens in liver with reference to its significance in liver injury.

Abstract Indirect immunoperoxidase stainings for hepatitis B core and surface antigens (HBc&s Ag) were applied to formalin-fixed paraffin sections in 113 liver specimens from 56 patients. Many cytomorphologic staining characteristics of HBc&s Ag were illustrated, and the percentages of the cellular population positive for HBc&s Ag were estimated for all specimens in order to provide the basis for general analyses. The quantitative expressions and the topographic distribution of HBc&s Ag were assessed with respect to their significance and implication in histopathologic reactions. A definitive relationship or relevance was neither established nor completely excluded due to the size of samples. However, cytomorphologically the membranous expression of HBc&s Ag was shown often in association with acute lobular hepatitis and chronic active hepatitis. This observation supports the concept that the membranous expression may be the prerequisite for immune mediated hepatitic injury in viral hepatitis. In this study we also carried out indirect immunoferritin and immunoperoxidase electron microscopy for HBc&s Ag on formalin-fixed liver specimens. The results assured the validity of the light microscopic immunohistologic procedures. The immunoelectron microscopy confirmed the presence of core antigen in the Dane particles formation that takes place in the cisternae of endoplasmic reticulum. The significance of the cytoplasmic core antigen and the possible role of immunoelectron microscopy in the elucidation of mechanisms of hepatitic injury were discussed.
