Abstract:
Maise is a promising crop that stabilises crop production in the arid climatic conditions of the Trans-Urals region. To obtain maise feed in this region, especially given the short frost-free period, earlymaturing hybrids are cultivated, and technologies that allow for stable yields are used, typically intensive ones that involve active weed control (which is particularly relevant for row crops) and optimisation of the plant nutrition system. With the systematic increase in the prices of production inputs, primarily herbicides, mineral fertilisers, and fuel and lubricants, it is essential to c

Abstract:
A methodological approach to determine the optimum time to control weeds that integrates aspects of weed biology, weed-crop competition, and economics is presented. The approach is based on the concept of Time Density Equivalent: this is defined as the density of weed plants that germinate with the crop and compete until harvest that causes the same yield loss caused by a group of weeds with a given density, time of emergence, and time of removal. A model was developed that accounts for pattern of weed emergence and permits determination of timing of weed control that minimizes economic loss d

Abstract:
Weed control in vineyards is essential to allow optimal vines development. In this study, three different techniques (hoeing, chemical control, and mulching) used in vineyard’s under-row weed control were compared considering their: operative and economic aspects, energy consumptions and environmental impacts. Trials were performed in a vineyard located in Canelli (AT), Italy, characterized by 3 different gradient slopes (<5%, 10-15%, >20%). Each technique has been tested in 3 adjacent rows per each of the 3 vineyard slopes (randomized block test). Two weed control treatments were perfor

Abstract:
There are three primary activities that characterize the discipline of Weed Science. These activities are weed technology, weed biology, and the ethics of weed control. Each of these activities needs to be considered as herbicide-tolerant crops (HTCs) are introduced. HTCs are the most recent refinement in the existing technology to control weeds. The potential benefits from the improved weed control must be weighed against possible increased costs of production and potential for genes that control herbicide tolerance to escape into non-tolerant plant populations.

This review examines the impact of herbicidal weed management on crop growth, weed density, weed biomass, yield, and the economic aspects of direct-seeded rice (Oryza sativa L.) cultivation. Effective weed control is critical for maximizing rice yields and promoting sustainable agricultural practices. The application of herbicides has been shown to significantly reduce weed density and biomass, which in turn enhances crop growth and increases yield potential. Moreover, herbicide use can decrease labor costs associated with manual weeding, contributing to overall economic efficiency in rice pro

Abstract:
Cultural practices, such as delayed crop seeding, tillage, black fallow, crop rotation, hand weeding, and competitive crops, when used to replace herbicides, provide an opportunity to reduce the selection pressure that causes weeds to become resistant to herbicides. Herbicides on the other hand reduce the selection pressure that causes weeds to resist cultural practices. Rotation of the two systems should then delay resistance to both systems. Growers consider many factors in addition to weed resistance in selecting herbicide or cultural weed control, from associated convenience to economic po

The economic aspects of fouling are presented in terms of antifoulant effectiveness in reducing cleaning costs and lost profits caused by charge cutback, required for furnace cleanout.

Abstract:
The need to control the risk that accompanies businesses in their day- to-day operations, and at the same time changing economic conditions make risk management an almost indispensable element of economic life. Selection of the main aspects of the selected phases of the risk management process: risk identification and risk assessment are related to their direct relationship with the subject matter (risk identification to be managed; risk analysis leading to the establishment of a risk hierarchy, and, consequently, the definition of risk control’ methods) and its purpose (bringing the risk to a

Abstract:
Systematic information on all aspects of agriculture is a significant tool in finding solutions to various problems. This project was initiated to develop a searchable database on taxonomy, host plants, geographic distribution, economic importance and control of scale insects (Hemiptera: Coccoidea). A systematic database has been developed for 17 families of scale insects, namely, Aclerdidae, Asterolecaniidae, Beesoniidae, Carayonemidae, Cerococcidae, Coccidae, Conchaspididae, Dactylopiidae, Eriococcidae, Halimococcidae, Kerriidae, Lecanodiaspididae, Micrococcidae, Ortheziidae, Phenacoleachiid

Abstract:
Stress corrosion cracking of line pipe from the soil side involves slow crack growth at stresses which may be as low as half the yield strength, this slow crack growth continuing until the crack penetrates the wall to produce a leak or until the stress intensity on the uncracked ligament reaches the value for a fast fracture to penetrate the wall thickness. The controlling parameters that contribute to the mechanism of failure, essentially involving growth by dissolution in the grain boundary regions, are, as with other systems displaying such failure, electrochemical, mechanical, and metallur

Abstract:
Abundant empirical evidence links well-functioning institutions and good governance to better economic and social outcomes. It is thus an important challenge to determine which conjunction of factors produces better institutions. Along this line, the objective of this paper is twofold. First, it examines the existing results of the literature on this matter in a critical way, tries to assess their robustness, and explores alternative methodology. Second, it makes use of a more comprehensive database, including all the aspects previously analyzed in a separate manner, to derive systematic empir

Abstract:
This study presents a baseline survey for the Rural Agro-enterprise Partnership for Inclusive Development and Growth (RAPID-Growth) project implemented by the Department of Trade and Industry. Operating in six regions of Mindanao and Region VIII, the project focuses on key value chains, including cacao, coconut, coffee, and processed fruits and nuts. The study delves into the current conditions of smallholder farming households and farmer organizations (FOs), complementing another PIDS study on matching grants as a strategy for enterprise development (Umlas and Briones 2023).

Abstract:
Geographic maps have been of military and economic importance throughout the ages. Rulers have commissioned maps to control the financial, economic, political, and military aspects of their sovereign entities. Large scale projects like the Ordnance Survey in the UK in the late 18th century, and the Lewis and Clark Expedition a few decades later to map the American West, are early examples of trailblazing efforts to create accurate modern maps of high strategic importance.

Abstract:
The Mississippi National River and Recreation area (MISS), situated along a 116 km stretch of the Mississippi River through the Minneapolis and St. Paul urban corridor, encompasses ~21,800 ha of public and private land. In 2022, the Great Lakes Inventory and Monitoring Network (GLKN) resampled permanent forest monitoring sites in the park, marking the second assessment of these sites, which were established and initially sampled in 2011. The goal of this long-term monitoring project is to provides managers with routine updates on which to base management decisions; these data can also be used

Abstract:
Symbiotic bacteria have been shown to influence host reproduction and defense against biotic and abiotic stressors, and this relates to possible development of a symbiont-based control strategy. This project was based on the hypothesis that symbionts have a significant impact on Culicoides fitness and vector competence for animal viruses. The original objectives in our proposal were: 1. Molecular identification and localization of the newly-discovered symbiotic bacteria within C. imicola and C. schultzei in Israel and C. sonorensis in California. 2.
