The Right

For those who approach literary studies with literary sensitivity, an immediate problem arises. They cannot overlook style, their own or that of others. Through their concern with literature they have become aware that understanding is a mediated activity and that style is an index of how the writer deals with the consciousness of mediation. Style is not cognitive only; it is also recognitive, a signal betraying the writer's relation, or sometimes the relation of a type of discourse, to a historical and social world. To say that of course words are a form of life is not enough: words at this level of style intend a statement about life itself in relation to words, and in particular to literature as a value-laden act. Thus, even without fully understanding it, one is alerted by a similarity in the opening of these two essays: The Right Reverend Father in God, Lancelot Bishop of Winchester, died on September 26th, 1626. During his lifetime he enjoyed a distinguished reputation for the excellence of his sermons, for the conduct of his diocese, for his ability in controversy displayed against Cardinal Bellarmine, and for the decorum and devotion of his private life. (Eliot, Lancelot 13) One afternoon, Walter Benjamin was sitting inside the Café des Deux Magots in Saint Germain des Prés when he was struck with compelling force by the idea of drawing a diagram of his life, and knew at the same moment exactly how it was to be done. He drew the diagram, and with utterly typical ill-luck lost it again a year or two later. The diagram, not surprisingly, was a labyrinth. (Eagleton, Pref.)

Winged bean (Fabaceae) is a tropical crop that has high nutrient content, and almost all parts of the plant are edible. The research aimed to evaluate the growth and production of winged bean in an intercropping system with tomato. The study was conducted at the Cikabayan Experimental Field of Bogor Agricultural University, Bogor, Indonesia, in a randomized block design with three replications during the rainy season of December 2017 to June 2018. Winged beans were planted in high and low population densities and intercropped with three tomato genotypes, “Tora”, F70030081-12-16-3 and “Apel Belgia”. Monoculture winged bean was assigned as control. Tomatoes were planted between the rows of the winged beans in the intercropping treatment. The results showed that the growth of winged bean in monoculture and intercropping systems was not significantly different. The photosynthetic activity of winged bean at three to five weeks after planting remained high, indicating that the vegetative growth was optimal in both systems. Intercropping increased the winged bean number of pods per plant by 12.66-19.52% compared to monoculture, irrespective of population density. Therefore, winged bean could be considered as suitable to grow in intercropping systems.

Preparation of Natural multi-nutrient Slow Release Fertilizer (NSRF) aims to reduce the environmental burden from some waste and increase the efficiency of fertilizer in releasing nutrient content. In this study,slow-release fertilizer was prepared from all natural components from waste which aredried chicken manure (N source), struvite (P source), and palm empty fruit bunch ash (K source). The equal weight of the three main nutrient sources was used with the addition of starch powder as the binder by 10%, 15% and 20% of the total nutrient mixture. The mixture of all nutrient with binder was granulated using pan granulator. Dried NSRF granule was tested using sand bed release method to observe the release profile of the contained nutrient. Based on the results of a 30-day leaching study, it was found that increasing concentration of binder will reduce the release of the nutrient from NSRF granules.

The Impact

Moina macrocopa was cultured with different animal manures (chicken manure, pig manure and cow manure) and food waste to determine the impact of these food sources on its mass production. All diets were provided at five different concentrations: 500, 1000, 2500, 5000 and 10000 ppm. Gross and net reproductive rates were higher in 1000 ppm concentration of food waste medium and the highest average population growth was obtained of about 9 org mL-1 whereas pig manure treatment showed the lowest among all the culture medium. The highest population density was observed in low concentration treatments, on the contrary, higher concentrations showed an adverse effect on M. macrocopa cultivation. The results of this study suggest that 1000 ppm concentration of food waste produces better results than other animal manures which showed the highest population density and exhibited a comparatively higher percentage of highly unsaturated fatty acids than the other treatments and could be an inexpensive and sustainable cultivation approach of Moina macrocopa.
