Improving Vegetative Growth of Sweet Corn Through Filter Cake and Potassium Application

Corn is a widely consumed cereal crop. To improve plant growth and yield, repairing the cultivation technique and environmental modification can be done through organic or inorganic fertilizer addition. The aim of this research was to identify an interaction between potassium and filter cake to corn vegetative growth. This research used Factorial Randomized Block Design with two factors. The first factor was the filter cake dose (0, 10, and 20 tone ha-1and second factor is potassium dose (100, 150, and 200 kg ha-1). There were nine treatments, and they were repeated three times. The variables analyzed were vegetative growth such plant height, number of leaves, length, and volume root. The result showed that a combination of filter cake (20 tone ha-1) and potassium (150 kg ha-1) had the highest plant height at 42 DAP. Potassium independently affected the number of leaves at 24 and 48 DAP. Length of root was independently effected by filter cake application. Keywords: filter cake, pottasium, sweet cor

The Contribution of the Agricultural Sector to Community Welfare in the Cirebon District

Gedong Gincu mango (GGM) is a leading commodity in the Cirebon district. It’s cultivated intensively in five sub-districts and is a source of income for the community. The study aimed to analyze the contribution of the agriculture sector to community welfare, especially in the Cirebon district. This research was conducted from August to October 2020 in the five sub-districts that produce GGM. Descriptive, quantitative field surveys were provided to 300 participants and multiple linear regression models were used to analyze the data. The results showed that the agricultural sector has contributed to the GRDP, but the extent to which it does so varied between the five sub-districts. The agricultural sector in the Sedong and Greged sub district had the highest contribution to the GRDP, but they both have the lowest score on the Human Development Index (HDI). This suggested that the existence of a leading GRDP does not guarantee high community welfare in GGM producing areas. HDI was found to have a strong correlation to the GRDP of an area. Economic development affects community welfare as suggested by the HDI. Keywords: gedong gincu mango, human development index, gross regional domesti

Chiral drag force

We provide a holographic evaluation of novel contributions to the drag force acting on a heavy quark moving through strongly interacting plasma. The new contributions are chiral in that they act in opposite directions in plasmas containing an excess of left- or right-handed quarks and in that they are proportional to the coefficient of the axial anomaly. These new contributions to the drag force act either parallel to or antiparallel to an external magnetic field or to the vorticity of the fluid plasma. In all these respects, these contributions to the drag force felt by a heavy quark are analogous to the chiral magnetic effect on light quarks. However, the new contribution to the drag force is independent of the electric charge of the heavy quark and is the same for heavy quarks and antiquarks. We show that although the chiral drag force can be non-vanishing for heavy quarks that are at rest in the local fluid rest frame, it does vanish for heavy quarks that are at rest in a suitably chosen frame. In this frame, the heavy quark at rest sees counterpropagating momentum and charge currents, both proportional to the axial anomaly coefficient, but feels no drag force. This provides strong concrete evidence for the absence of dissipation in chiral transport, something that has been predicted previously via consideration of symmetries. Along the way to our principal results, we provide a general calculation of the corrections to the drag force due to the presence of gradients in the flowing fluid in the presence of a nonzero chemical potential. We close with a consequence of our result that is at least in principle observable in heavy ion collisions, namely an anticorrelation between the direction of the CME current for light quarks in a given event and the direction of the kick given to the momentum of all the heavy quarks and antiquarks in that event.Comment: 28 pages, small improvement to the discussion of gravitational anomaly, references adde

Thermodynamics and Instabilities of a Strongly Coupled Anisotropic Plasma

We extend our analysis of a IIB supergravity solution dual to a spatially anisotropic finite-temperature N=4 super Yang-Mills plasma. The solution is static, possesses an anisotropic horizon, and is completely regular. The full geometry can be viewed as a renormalization group flow from an AdS geometry in the ultraviolet to a Lifshitz-like geometry in the infrared. The anisotropy can be equivalently understood as resulting from a position-dependent theta-term or from a non-zero number density of dissolved D7-branes. The holographic stress tensor is conserved and anisotropic. The presence of a conformal anomaly plays an important role in the thermodynamics. The phase diagram exhibits homogeneous and inhomogeneous (i.e. mixed) phases. In some regions the homogeneous phase displays instabilities reminiscent of those of weakly coupled plasmas. We comment on similarities with QCD at finite baryon density and with the phenomenon of cavitation.Comment: 62 pages, 13 figures; v2: typos fixed, added reference

Determinant Factors of Dividend Payments in Brazil

This study identifies factors that shaped cash disbursement distribution policies employed by Brazilian public companies listed on the Brazilian Securities, Commodities and Futures Exchange (BM&FBOVESPA) from 1995 to 2011. Relationships between Dividends/Total Assets and potential determinants discussed in the literature, including firm size, corporate governance, profitability, leverage, market to book, liquidity, investment, risk, profit growth, information asymmetry and agency conflict, are examined. The following econometric methods are employed: (1) Tobit, given the nature of the dividend data, and (2) the Generalized Method of Moments (GMM) to control for endogenous regressors. Significant positive variables found include size, return on assets (ROA), market to book, liquidity and profit growth. It can thus be inferred that larger firm size, profitability, market value, liquidity and profit growth correlate with greater firm pro pensity to distribute money to shareholders, thus supporting the theory of corporate finance. Significant negative variables found include leverage, liquidity squared, capex, beta and tag along 100%. It is thus inferred that more significantly leveraged companies that invest more heavily in fixed assets and that exhibit high liquidity, higher risk and less conflict between controlling and minority shareholders will be less likely to pay dividends to shareholders.</p

Holographic Lessons for Quark Dynamics

We give a brief overview of recent results obtained through the gauge/gravity correspondence, concerning the propagation of a heavy quark in strongly-coupled conformal field theories (such as N=4 super-Yang-Mills), both at zero and finite temperature. In the vacuum, we discuss energy loss, radiation damping, signal propagation and radiation-induced fluctuations. In the presence of a thermal plasma, our emphasis is on early-time energy loss, screening and quark-antiquark evolution after pair creation. Throughout, quark dynamics is seen to be efficiently encapsulated in the usual string worldsheet dynamics.Comment: Invited review for a Journal of Physics G topical volume on gauge/gravity duality applications to QCD matter and ultrarelativistic heavy-ion collisions. v2: Reference adde

The method used in this activity through education and training with theaim at improving farmers’ knowledge in the processing agricultural waste and waste wood craft a quality organicfertilizer to use local microorganisms. Training wass going well and in the family atmosphere. Material extensionand how to manufacture quality organic fertilizer were easily understood by farmers. All farmers can make theirown organic fertilizer from organic waste. Preparation of local microorganisms as decomposers bioactivator was easyto handle. Knowledge of farmers on organic waste still needs to be improved to prevent environmental pollution
