Controlled crop growth parameters, such as average air velocity, air temperature, and relative humidity (RH), inside the greenhouse are necessary prerequisites for commercial greenhouse operation. Frequent overshoots of such parameters are noticed in the Middle East. Traditional heating ventilation and air-conditioning (HVAC) systems in such greenhouses use axial fans and evaporative cooling pads to control the temperature. Such systems fail to respond to the extreme heat load variations during the day. In this study, we present the design and implementation of a single span, commercial greenhouse using box type evaporative coolers (BTEC) as the backbone of the HVAC system. The HVAC system is run by a fully-automated real time feedback-based climate management system (CMS). A full-scale, steady state computational fluid dynamics (CFD) simulation of the greenhouse is carried out assuming peak summer outdoor conditions. A pilot study is conducted to experimentally monitor the environmental parameters in the greenhouse over a 20-h period. The recorded data confirm that the crop growth parameters lie within their required ranges, indicating a successful design and implementation phase of the commercial greenhouse on a pilot scale.

Drilling Waste

Development of the Russian oil and gas fields in the Arctic requires ensuring industrial and environmental safety of conduct of the operations. Large and unique oil and gas condensate fields are discovered in the southern part of the Kara Sea. The Kamennomysskoye-Sea, Severo-Kamennomysskoye, Semakovskoye, Parusovoye, etc. gas condensate fields are located in the Ob Bay of the Kara Sea. The raw material base of the Severo-Obskoye gas condensate field, unique in terms of the reserves, will become the basis for future Arctic LNG projects. Based on the published data, the initial recoverable total hydrocarbon resources in the Ob and Taz bays are about seven billion tons. Active exploration and commissioning of the already discovered fields require the large volumes of well drilling in a freezing sea, the presence of permafrost, and gas hydrates. During construction of the wells and operation of the offshore ice-resistant oil and gas production platforms, it is required to ensure the disposal of drilling waste (cuttings) and domestic water. There are two technologies for waste disposal — injection into the reservoir or into the clay formations. The first one is used in onshore fields, the second one — on the shelf. Injection into a clay reservoir is successfully used in the Lunskoye gas field on the shelf of the Sakhalin island, and on the Prirazlomnoye oil field in the Pechora Sea. The possibility of using the method and the selection of a reservoir for injecting waste into it requires a geological justification, and the reservoir should ensure a stable injectivity of the required volume. The article presents the results of modeling the injection into the formation of drilling waste, and the waste of the household activities for the Kamennomysskoe-Sea gas condensate field. Calculation was made concerning the zone of absorption of the technological waste into the designed well of the offshore ice-resistant stationary platform. Formation allocation for waste injection was made according to the data of a complex of offshore wells geophysical studies. Three packs of sandy-argillaceous rocks with high reservoir properties were selected as the object of industrial waste disposal. Сalculation was carried out related to the radius of the spread of waste (effluent) in the target reservoir considering drilling and operation of twenty five wells, the construction of which is planned for five years. The results of modeling the process of pumping industrial waste of various types into an absorption well showed that the planned volumes can be successfully disposed of in the selected objects. This will allow to ensure functioning of the marine industry and its environmental safety.

Attitudes toward the use of medicinal marijuana have continued to change, which is reflected in the number of states that have passed legislation allowing for its use and in the number of states petitioning to place this matter on upcoming ballots. Understanding the attitudes of rehabilitation professionals toward medicinal marijuana use is important as they are responsible for providing appropriate support and services to all consumers and will be responsible for navigating through uncharted territory when it comes to this new trend. Their attitudes might determine how they approach the ensuing demands and consequences associated with the use of medical marijuana by their consumers. This manuscript reports the results of a pilot study conducted as a means to determine the most appropriate way to measure the attitudes of these professionals toward the use of marijuana for medicinal purposes. Results from the pilot are used to inform the researchers on the appropriateness of their study design and implementation procedures before a full scale study is conducted..

In the current information-saturated world of knowledge societies, universities are at risk of training technical experts who hold myopic views of the future, and leaders who are ill-equipped to address the systemic nature of current global ecological, economic, and political crises. In this context, and taking into account the obstacles posed, and the opportunities provided, by contemporary societies, the current paper discusses the design and implementation of courses which not only rely upon, but also increase the transformative power of Environmental Education (EE) and Education for Sustainability (EfS) within Higher Education. We rely on our experience in two college courses, in Greece and the USA, to provide reflections on the integrative, interdisciplinary and collaborative dimensions of EE/EfS and on their ability to challenge neoliberal discourse that permeates contemporary knowledge societies. The qualitative methodology utilized in the paper rests on a self-study research approach and on end-of-term course evaluations filled by the students. We propose that successful design and implementation of EE/EfS courses depends upon the instructors’ (and their institutions’) ability to democratize and rethink the classroom (beyond its physical limits and into the community), to help students self-examine their place in the system, and to create assignments that test the learning process rather than learning outcomes.
