Microorganism isolates used in plant protection were obtained from the College ofAgriculture / University of Baghdad. Its purity was assured. The microbial biokit was preparedthrough using several unsatisfactory and environmentally friendly isolate. The bioactivity ofbiokit were studied in laboratory and showed susceptibility in removing contaminants. Theresults showed that the biomass of the isolates prior to the loading process on a mediumcontaining crude oil as a single carbon source of 5 g/ L, which indicates growth ability andefficiency in the decomposition of pollutants when increase the isolates biomass more than 3 g /L, as well as the appearance of turbidity in the media compared to the control sample (mediawithout oil), and obtained bioemulsifier with a concentration of 2.3 g / L. The chemical analysisof the samples under study was carried out using Gas Chromatography (GC) and GC-MScompared with a non-treatment (control). The results showed the appearance of 43 topographic peaks each indicating a chemicalcompound in the control sample, while a number of these peaks disappeared and a space wasreduced in other peaks that refers to the concentration of compounds, in the biomass sample, andreached the number of peaks in 26, indicating the efficiency of the biokit in the oildecomposition and dismantling of hydrocarbons. The increase in the number of livemicroorganisms and the incubation period is more than 28 days by increasing the growthintensity in the third week may be due to decomposing oil compounds and their exploitation innutrition, where crude oil provides a source of carbon and energy for microorganism’s isolates.In other results showed that the mass of crude oil was converted to a mass of gel andemulsification compared to the control sample after seven days period at a temperature of 28±2°C, Which is characterized by low toxicity and easy decomposition and reduces the surfacetension of hydrocarbons and makes them more solubility and preparation for the dismantling oflife and increase the rate of disintegration. The biokit was tested for retention in storageconditions for a period of one year. at alone prior to the production of the biokit, which showed poor storage capacity. We concludethat biomass has the potential to treat hydrocarbons (oil contaminants) in the environment.

In a four year grazing trial with dairy cows the application of 5000 kg lime/ ha (applied in two applications of 2500 kg/ha in winter of the first two years) significantly increased annual pasture production in two of the four years and dairy production in one year. In three of the four years lime significantly increased pasture growth over summer/autumn with concurrent increases in milk production. In the last year of the trial lime had little effect on pasture growth but a relatively large increase in milkfat production resulted. A higher incidence of grass staggers was recorded on the limed farmlets in spring for each of the four years. In the second spring immediately following the second application of lime significant depressions in both pasture and plasma magnesium levels were recorded. By the third spring differences in plasma magnesium levels were negligible but small depressions in herbage magnesium resulting from lime continued to the end of the trial. Lime significantly raised soil pH, Ca and Mg levels but had no effect on either soil K or P. As pH levels of the unlimed paddocks were low (5.2-5.4) in each autumn and soil moisture levels were increased by liming, these factors may suggest possible causes for the seasonality of the pasture response to lime

The aim of the research project solved at the University of Finance and administration is to construct a new bankruptcy model. The intention is to use data of the firms that have to cease their activities due to bankruptcy. The most common method for bankruptcy model construction is multivariate discriminant analyses (MDA). It allows to derive the indicators most sensitive to the future companies’ failure as a parts of the bankruptcy model. One of the assumptions for using the MDA method and reassuring the reliable results is the normal distribution and independence of the input data. The results of verification of this assumption as the third stage of the project are presented in this article. We have revealed that this assumption is met only in a few selected indicators. Better results were achieved in the indicators in the set of prosperous companies and one year prior the failure. The selected indicators intended for the bankruptcy model construction thus cannot be considered as suitable for using the MDA method.

This article explores the case of N’Guyen Van Binh, a South Vietnamese political prisoner exiled for his alleged role in “Poukhombo’s Rebellion” in Cambodia in 1866. Although Van Binh’s original sentence of exile was reduced to one year in prison he was nonetheless deported and disappeared into the maw of the colonial systems of indentured servitude and forced labor; he likely did not survive the experience. He was thus the victim of injustice and his case reveals the at best haphazard workings of the French colonial bureaucracy during the period of transition from the Second Empire to the Third Republic. While the documentary record is entirely from the perspective of the colonizers, reading between the lines we can also learn something about Van Binh himself including his fierce will to resist his colonial oppressors.

The authors explore media distrust among a sample of precarious and gig workers interviewed during the COVID-19 pandemic. Although these left-leaning respondents initially increased their media consumption at the outset of the pandemic, they soon complained of media sensationalism and repurposed a readily available cultural tool: claims of “fake news.” As a result, these unsettled times have resulted in a “diffusion of distrust,” in which an elite conservative discourse of skepticism toward the media has also become a popular form of compensatory control among self-identified liberals. Perceiving “fake news” and media sensationalism as “not good” for their mental health, respondents also reported experiencing media burnout and withdrawing from media consumption. As the pandemic passes its one-year anniversary, this research has implications for long-term media coverage on COVID-19 and ongoing media trust and consumption.

We use a dataset for the group of G7 countries and China to study the out-of-sample predictive value of uncertainty and its international spillovers for the realized variance of crude oil (West Texas Intermediate and Brent) over the sample period from 1996Q1 to 2020Q4. Using the Lasso estimator, we found evidence that uncertainty and international spillovers had predictive value for the realized variance at intermediate (two quarters) and long (one year) forecasting horizons in several of the forecasting models that we studied. This result holds also for upside (good) and downside (bad) variance, and irrespective of whether we used a recursive or a rolling estimation window. Our results have important implications for investors and policymakers.

AbstractThis article offers a sensitive reading of oppositional political cartoons in Togo in the early 1990s, during the period of structural adjustment, which was accompanied by the swift reversal of democratizing trends and the restoration of authoritarian rule. Togolese satirists perceived this moment as a moment of “fraudonomics”, thus contesting rampant corruption and clientelism in politics. They poked fun at the president, local politicians, businesspeople, and bureaucrats of the international institutions. The article begins by examining the making of satirical newspapers with a focus on the biographies of the satirists. As students, they started out on the adventure of publication with their own money and learned most of their drawing and printing techniques as work progressed. Secondly, an analysis of the readership shows that, although the satirical newspapers were a crucial element of the media in the early 1990s, it was mostly an elitist and urban phenomenon. The third section analyses the changing visual repertoire of contention through in-depth analysis of four selected caricatures.

Thirty-one patients with unilateral or bilateral hydrocele were treated by percutaneous needle aspiration and subsequent sclerotherapy with rolitetracycline. Thirty patients were considered cured after a follow-up of one year. In 20 pts. the procedure proved to be definitive after the first sitting, in 6 cases the treatment was repeated twice and in 4 cases three times. Only in 1 a recurrence was observed after the third treatment. No complications related to the procedure were recorded.
