Analysis Efficiency Marketing System of Fresh Layang Fish (Decapterus Russeli) on Pelabuhan Fish Auction Place in Tegal City

Marketing is an important aspect in running fishing business because it is an economic activity that influences the fluctuation of fishermen\u27s income. The production can be useless if the price is low, thus, marketing has to be good and efficient. This research is about the efficiency of the marketing system of fresh fish layang (Decapterus russeli) in the fish auction place. Specifically, this research is to know : 1) the marketing system of fresh fish layang in Tegal City. 2) the marketing margin of fresh fish layang in Tegal City. 3) the distribution flow of fresh fish layang in Tegal City. 4) the reason fishermen sell their products in the Fish Auction Place. The method use in this research is descriptive analysis method, The registration data and literature study. Based on the analysis, it is known that the marketing system of fresh in the Fish Auction Place, seen from the marketing cost calculation, purchasing price, selling price and profit is < 1, which means efficient. And if seen from the marketing margin, the most efficient flow is channel 4 (the 4th channel). Meanwhile, the reason why fishermen sell their Fish Auction Place is because of the guarantee that their product will be sold. Fish is a product that is easily broken and rotten. Therefore, the guarantee that the product will be sold, can minimize loss risk for fisherman

Control and Data Flow Execution of Java Programs

Since decade understanding of programs has become a compulsory task for the students as well as for others who are involved in the process of developing software and providing solutions to open problems. In that aspect showing the problem in a pictorial presentation in a best manner is a key advantage to better understand it. We provide model and structure for Java programs to understand the control and data flow analysis of execution. Especially it helps to understand the static analysis of Java programs, which is an uttermost important phase for software maintenance. We provided information and model for visualization of Java programs that may help better understanding of programs for a learning and analysis purpose. The idea provided for building visualization tool is extracting data and control analysis from execution of Java programs. We presented case studies to prove that our idea is most important for better understanding of Java programs which may help towards static analysis, software debugging and software maintenance

Boron-Doped Graphene as a Promising Anode Material for Potassium-Ion Batteries with a Large Capacity, High Rate Performance, and Good Cycling Stability

Potassium-ion batteries (KIBs), as alternatives to lithium-ion batteries (LIBs), have attracted increasing attention due to the abundance of K in the Earth’s crust. Here, using first-principles calculations, we have found that boron (B)-doped graphene is a promising anode material for KIBs. The studied B₄C₂₈ structure has a large specific capacity of 546 mAh/g, a small migration barrier of 0.07 eV, and a moderate potassiation voltage of 0.82 V to suppress the formation of a SEI layer. Moreover, B-doped graphene with a doping concentration of 12.5 at. % is metallic with good electron conductivity that can improve rate performance. Also, B doping makes the substrate electron-deficient and results in significant charge transfer from K to the substrate, thus preventing K atoms from clustering, inhibiting dendrite growth, and leading to a good cycling stability

Sequence Affects the Cyclization of DNA Minicircles

Understanding how the sequence of a DNA molecule affects its dynamic properties is a central problem affecting biochemistry and biotechnology. The process of cyclizing short DNA, as a critical step in molecular cloning, lacks a comprehensive picture of the kinetic process containing sequence information. We have elucidated this process by using coarse-grained simulations, enhanced sampling methods, and recent theoretical advances. We are able to identify the types and positions of structural defects during the looping process at a base-pair level. Correlations along a DNA molecule dictate critical sequence positions that can affect the looping rate. Structural defects change the bending elasticity of the DNA molecule from a harmonic to subharmonic potential with respect to bending angles. We explore the subelastic chain as a possible model in loop formation kinetics. A sequence-dependent model is developed to qualitatively predict the relative loop formation time as a function of DNA sequence

Allylic Substitution on Cyclopentene and -hexene Rings with Alkynylcopper Reagents

Substitution of cyclic allylic picolinates with a reagent derived from TMS-CCMgBr and a copper salt was investigated. Although the previous type of reagent (TMSCCMgBr and CuBr·Me₂S) developed for linear allylic picolinates was less product selective and regioselective, the Cu(acac)₂-derived reagent was highly selective (94–95%) to afford the S_N2′ product in good yields. As an application, several C–C bond formations at the acetylenic carbon and the synthesis of the PG intermediate were studied with success

Removal of Elemental Mercury from Flue Gas by Thermally Activated Ammonium Persulfate in A Bubble Column Reactor

In this article, a novel technique on removal of elemental mercury (Hg⁰) from flue gas by thermally activated ammonium persulfate ((NH₄)₂S₂O₈) has been developed for the first time. Some experiments were carried out in a bubble column reactor to evaluate the effects of process parameters on Hg⁰ removal. The mechanism and kinetics of Hg⁰ removal are also studied. The results show that the parameters, (NH₄)₂S₂O₈ concentration, activation temperature and solution pH, have significant impacts on Hg⁰ removal. The parameters, Hg⁰, SO₂ and NO concentration, only have small effects on Hg⁰ removal. Hg⁰ is removed by oxidations of (NH₄)₂S₂O₈, sulfate and hydroxyl free radicals. When (NH₄)₂S₂O₈ concentration is more than 0.1 mol/L and solution pH is lower than 9.71, Hg⁰ removal by thermally activated (NH₄)₂S₂O₈ meets a pseudo-first-order fast reaction with respect to Hg⁰. However, when (NH₄)₂S₂O₈ concentration is less than 0.1 mol/L or solution pH is higher than 9.71, the removal process meets a moderate speed reaction with respect to Hg⁰. The above results indicate that this technique is a feasible method for emission control of Hg⁰ from flue gas

Innovation drive differs from investment drive and resource drive in that it focuses on knowledge and skills to promote productivity growth. By integrating technical standards within the framework of an innovation-driven development system in this work, theoretical implications for this development strategy may be revealed. Following our theoretical study, we built a PECM utilizing China’s inter-provincial panel data from 2007 to 2020 to investigate the long and short-term relationships between standardization, R&D, and innovation-driven development. The following are the key findings: First, both standardization and R&D are the nation’s critical engines of innovation-driven development. Second, standardization has the greatest impact on TFP through improving technical efficiency, whereas R&D drives both technical development and technical efficiency improvement. Third, while the influence of technical standard drafters’ production scale on scale efficiency was insignificant from 2007 to 2013, it became substantial after 2014 with China’s macroeconomic reform of "transforming the mode and changing the structure."</div
