DIFFERENT SOILLESS CULTURE SYSTEMS AND THEIR MANAGEMENT

Soilless culture is growing plants without use of soil as a rooting medium, and divided into water culture and substrate culture. Among the water culture techniques, float hydroponics is adopted for the cultivation of fresh-cut leafy vegetables and aromatic plants. Substrate culture by using plastic bags has been applied successfully at commercial level for fruiting vegetables. Production scale, crops, growing cycles and length of each cycle, cost and management skills should be considered as well as environmental concerns in the decision of soilless culture system. Therefore, closed loop systems have gained importance for increasing sustainability in soilless cultivation. This presentation aims to summarize different soilless culture systems and the potential of their use in vegetable production

Low strain rate mechanical performance of balsa wood and carbon fibre-epoxy-balsa sandwich structures

The focus of this study is the experimental assessment of the mechanical behaviour of balsa wood and its sandwich structures, where balsa serves as the core, supported by carbon fibre-epoxy skin layers. A comprehensive characterisation is conducted on the mechanical behaviour of balsa wood and carbon fibre-epoxy balsa core sandwich structures subjected to a range of low strain rates. Initially, the study undertakes a consistent procedure for sample preparation. Subsequently, the characterisation of the manufactured composite structures is performed experimentally. A stereo microscope is employed for a detailed visual inspection of the internal structure of the balsa wood and the sandwich structures. Furthermore, the mechanical characterisation is carried out with three-point bending tests at a range of strain rates from 0.1 % to 6 % strain per minute. This research reveals key findings about balsa wood and its sandwich structures, highlighting their performance and their sensitivity even under low strain rates

Basel Compliance and Financial Stability: Evidence from Islamic Banks

We find that compliance with the Basel Core Principles (BCPs) has a strong positive effect on the stability of conventional banks, and a positive but less pronounced effect on the stability of Islamic banks. We also find that the main impact of compliance is an increase in capital ratios, whereas other components of the Z-score are negatively affected. This reflects the desire of banks to be more closely integrated into the global financial system by holding higher capital ratios. The findings also justify the 2015 decision of the Islamic Financial Services Board to publish similar principles for Islamic banks

High gamma oscillations in medial temporal lobe during overt production of speech and gestures

The study of the production of co-speech gestures (CSGs), i.e., meaningful hand movements that often accompany speech during everyday discourse, provides an important opportunity to investigate the integration of language, action, and memory because of the semantic overlap between gesture movements and speech content. Behavioral studies of CSGs and speech suggest that they have a common base in memory and predict that overt production of both speech and CSGs would be preceded by neural activity related to memory processes. However, to date the neural correlates and timing of CSG production are still largely unknown. In the current study, we addressed these questions with magnetoencephalography and a semantic association paradigm in which participants overtly produced speech or gesture responses that were either meaningfully related to a stimulus or not. Using spectral and beamforming analyses to investigate the neural activity preceding the responses, we found a desynchronization in the beta band (15-25 Hz), which originated 900 ms prior to the onset of speech and was localized to motor and somatosensory regions in the cortex and cerebellum, as well as right inferior frontal gyrus. Beta desynchronization is often seen as an indicator of motor processing and thus reflects motor activity related to the hand movements that gestures add to speech. Furthermore, our results show oscillations in the high gamma band (50-90 Hz), which originated 400 ms prior to speech onset and were localized to the left medial temporal lobe. High gamma oscillations have previously been found to be involved in memory processes and we thus interpret them to be related to contextual association of semantic information in memory. The results of our study show that high gamma oscillations in medial temporal cortex play an important role in the binding of information in human memory during speech and CSG production

From short-term store to multicomponent working memory: The role of the modal model

The term “modal model” reflects the importance of Atkinson and Shiffrin’s paper in capturing the major developments in the cognitive psychology of memory that were achieved over the previous decade, providing an integrated framework that has formed the basis for many future developments. The fact that it is still the most cited model from that period some 50 years later has, we suggest, implications for the model itself and for theorising in psychology more generally. We review the essential foundations of the model before going on to discuss briefly the way in which one of its components, the short-term store, had influenced our own concept of a multicomponent working memory. This is followed by a discussion of recent claims that the concept of a short-term store be replaced by an interpretation in terms of activated long-term memory. We present several reasons to question these proposals. We conclude with a brief discussion of the implications of the longevity of the modal model for styles of theorising in cognitive psychology

Microscopic examination of placenta of rats prenatally exposed to Aloe barbadensis: A preliminary study

Aloe barbadensis is the most widely used both commercially and therapeutic properties. It has been used for an array of ailments since ancient times as a medicinal plant. There are more than 360 different species of Aloe. Its products have been used in health foods for medical and preservative purposes. The objective of this study was to search the effects of Aloe barbadensis on the rat's placenta. Gel form of Aloe barbadensis is used in the study. It is commercial, preserved but otherwise untreated form of Aloe Barbadensis gel capsul. Female Wistar Albino rats were divided into three groups. Placenta specimens from each groups were processed for the microscopic examination. Trophoblastic giant cells and spongiotrophoblasts were decreased in number after Aloe barbadensis; trophoblastic giant cells which showed degenerative changes. The nuclei of these giant cells were going degeneration characterized by pyknosis and bizarrely shaped. Extracellular matrix production around the cells was increased, thicker and more irregular basal membrane like formation around the cells. Decreased and abnormal vessel formation in labyrinth area was clear and reduced functional capacity of the trophoblastic barier. The study shows that, in the presence of Aloe barbadensis, relevant alterations associated with a possible compensatory adjustment to maintain adequate metabolic exchange take place in the structure of placenta. Our results also demonstrated that the exposure to Aloe barbadensis during pregnancy not led to fetal growth retardation, fetal death, abortion or teratogenic effect

Crop drying programme in Turkey

Proceedings of the 1998 World Renewable Energy Congress V. Part 2 (of 2) --20 September 1998 through 25 September 1998 -- Florence, Italy --The present status of agricultural crop drying practices in Turkey is investigated in this study. The emphasis of drying on market value, annual production and export values of some commercially important crops is given in a broad perspective. In the recent years, developing international market conditions in Europe, Middle East, and Central Asia has been encouraging to Turkey's fresh and dry agricultural crop export due to the rapidly increasing internal and external market demands. Grapes, apricots, black tea, figs, red pepper, and aromatic plants are the major exported agricultural crops, contributing annually 35 to 40 millions of USD$to Turkey's economics. From the view point of dried crop quality, drying of special crops are still an important topic for the agricultural sector. Traditionally used drying methods have many drawbacks. High air temperatures and relative humidity during the drying season promote the insect and mold development in harvested crops. Furthermore, theintensive solar radiation causes several quality reductions like vitamin losses or color changes in dried crops. Thus, the conventional drying methods do not meet the particular requirements of the related standards. To overcome these problems, producers should be made aware of the fact that the high quality of dried products can be sold to three or four fold prices and directed to the dryer investments. Moreover, the introduction of low cost and locally manufactured dryer offers a promoting alternative to reduce the excessive postharvest losses and also improve the economical situation of the farmers.The present status of agricultural crop drying practices in Turkey is investigated in this study.
