Various synthetic and natural antioxidants are used to reduce oxidation and its negative impact on the oil during the food frying process. Considering that some studies show the negative impact of synthetic antioxidants on the health of consumers, natural alternatives are being used more and more. BHA and BHT are synthetic antioxidants that are widely used in the food industryand a large number of natural compounds such as phenols, anthocyanins, flavonoids, vitamins, etc. show antioxidant properties. In this study, the antioxidant capacity of oregano and rosemary essential oil was tested and compared with the antioxidant capacity of BHA and BHT. The antioxidant capacity was evaluated by the removal of DPPH radicals and by iron reduction (FRAP). The results of this study showed that the studied essential oils exhibited antioxidant capacity. These oils have a high antioxidant capacity, however, compared to synthetic antioxidants, they show a significantly lower antioxidant capacity but they can be used as natural antioxidants during food processing.

Medicinal plants have become an increasing subject of interest worldwide due to the large amount of biologically active substances that have potential beneficial health properties. One of the more interesting popular medicinal plants is hawthorn (Crataegusspp.), a deciduous branched shrub that is increasingly used for health purposes. Various parts of this plant, including berries, flowers and leaves, are rich in nutrients and beneficial bioactive compounds that are effective in the treatment of numerous diseases. Honey is a natural sweetener produced by bees from plant secretions. Known for its nutritional and medicinal values, it gives strength to the body, which is why it is indispensable in the human diet. The combination of these two ingredients represents a significant source of vitamins and minerals in daily use, but also for use in various pharmaceutical and medical purpose. Taking into account all of the above, the aim of the work is to test samples of the mixture of honey and hawthorn in different proportions and determine the physical and chemical characteristics: pH value, electrical conductivity, refractive index, viscosity, water activity, HMF, DPPH. Based on the analysis, appropriate conclusions will be drawn and more information will be obtained about their quality and possible use as a food supplement. On the basis of the conducted analyses, it can be concluded that the parameter values are within the permitted limits defined by the Rulebook (Official Gazette Bosnia and Herzegovina No. 37/09). The analysis of the mentioned parameters showed that the chemical composition of the sample plays a major role in the value of the measurement results, and that Sample III has the best antioxidant properties.

The samples of stinging nettle were collected during June in the Tuzla region. Aqueous extracts were prepared from fresh and dried leaves in order to determinate and compare content of bioactive components and antioxidant potential. Conventional soxhlet, ultrasound assisted extraction and traditional maceration extraction were used as extraction methods. Quantitative determination of phenols and flavonoids was carried out using spectrophotometric methods. Antioxidant activity of nettle aqueous extracts was determined using ferric reducing antioxidant power and DPPH free radical scavenging activity. Extracts obtained by Soxhlet extraction showed the highest total phenolic and flavonoid content and expected the highest antioxidant capacity, while extracts obtained by maceration gave the lowest results.

Abstract The importance of evaluating the energy requirements of soil preparation operations is a concern of researchers specializing in agricultural equipment. To answer such a question, they have proposed several mathematical models for the evaluation of tensile strength. However, given the large number of parameters introduced in these models, the selection of one of these models under specific agro-pedological conditions often poses an issue. Knowing the difficulties of selecting a mathematical model from those proposed in literature, the work presented allows a judicious choice of the model to be used, taking into account the precise working conditions. The work employs the MERISE method (it is a method of analysis, design and management of IT projects) to realize this work. For these purposes, a computer program was designed to quickly determine the tractive effort from a system of information on predefined equipment and working conditions. This program is called DERT (Fr: Détermination de l‘Effort de Résistance à la Traction; En: Determination of Traction Resistance Effort) and grants the possibility to convert the traction effort into energy using the most appropriate mathematical model. This computer tool enables the establishment of a database on the tractive effort and energy requirements of mechanized agricultural work. Eighteen farms permitted testing the DERT program to evaluate the efforts using the appropriate models. A generalization of its use at the level of different farms will allow the creation of a national map of energy needs and thus the optimization of agricultural equipment and energy consumption.
摘要评估整地作业能量需求的重要性是农业设备专业研究人员关注的问题。为了回答这样一个问题，他们提出了几个评估抗拉强度的数学模型。然而，鉴于这些模型中引入了大量参数，在特定的农业土壤条件下选择其中一个模型往往会带来问题。由于知道从文献中提出的数学模型中选择数学模型的困难，所做的工作允许在考虑精确工作条件的情况下明智地选择要使用的模型。本工作采用MERISE方法（一种对it项目进行分析、设计和管理的方法）来实现这项工作。出于这些目的，设计了一个计算机程序，用于根据预定义设备和工作条件的信息系统快速确定牵引力。该程序被称为DERT（Fr:Détermination de l’Effort de RéResistanceàla Traction；En:Determination of Traction Resistance Effort），并允许使用最合适的数学模型将牵引力转换为能量。这种计算机工具能够建立一个关于机械化农业工作的牵引力和能量需求的数据库。18个农场允许测试DERT计划，以使用适当的模型来评估这些努力。在不同农场一级推广其使用，将有助于绘制国家能源需求地图，从而优化农业设备和能源消耗。

Abstract This study aims to analyse the energy of cucumber production in a greenhouse and examine the application of a multilayer perceptron to predict the productivity of an agricultural region in Nineveh Governorate. The research data were collected from experiments including fuel, fertilisers, pesticides, seeds, workers, electricity, and the number of hours worked in agricultural processes to produce cucumber crops. The results showed that the total energy consumption of the cucumber was 46,432.013 MJ·ha−1, while the output energy was 53,127.727 MJ·ha−1. The fungicide energy consumption, herbicide energy consumption and electricity energy consumption are considered the most critical variable in cucumber plantation procedures; its significance is the relative values of 100%, 99.7% and 93.3%. The impacts of human labour, P fertiliser, diesel fuel and N fertiliser on cucumber operation were 25,725 MJ·ha−1, 548.596 MJ·ha−1, 3,011.178 MJ·ha−1 and 7,244.545 MJ·ha−1, respectively. This research concludes that a multilayer perceptron neural network algorithm helps predict cucumber production and shows that the trained neural network produced minimal errors, indicating that the test model could predict a cucumber crop yield in Nineveh province.
