THE COMPOST, A SOURCE OF PLANT BENEFICIAL BACTERIA WITH BIOCONTROL POTENTIAL

Recycling the sewage sludge from treatment plants is a common activity. The resulting compost is usually rich in plant nutrients and beneficial microorganisms. However, compost properties greatly differ depending on the nature of the fermented biomass and fermentation processes. The aim of this study was to analyze the microbial load of three different composts, in order to detect new bacterial strains with plant protection properties. Isolated bacteria were microbiologically characterized and evaluated for their potential to reduce soil-borne phytopathogenic fungi. Results showed a microbial load of approximately 106 CFU/g of compost. In the analyzed samples it was revealed that as bacterial load increases, the fungal amount decreases. Analyzing some newly isolated bacteria obtained from these composts, a good biocontrol potential against soil-borne pathogenic fungi was revealed. Some of the isolated bacterial strains revealed antifungal activity against Rhizoctonia solani and Sclerotinia sclerotiorum. These bacteria showed good colonization capacity and lytic enzymes production, correlated to antimicrobial activity. These compost-originated bacteria reveal high potential in pathogens inhibition. Therefore, the analyzed composts are recommended not only as soil fertility improvers, but also as potential suppressors of soil-borne pathogens. Results revealed these composts as source of plant beneficial bacteria with biological control potential.

Assessing Coping Strategies and Outdoor Activities Among Older Adults During the COVID-19 Pandemic

Information is lacking on how older adults are coping during the pandemic. We explored coping strategies including outdoor activities among community-dwelling older adults (N = 115) 65 and older (mean age 76.45, 71.3% female). Using conventional content analysis, we analyzed responses to: 1) How are you coping with COVID-19? and 2) How often are you going outside during the pandemic and for what reasons? Most common activities are connecting with family and friends (some in person, others on the phone or virtually), reading, tv, game playing, and learning something new (e.g. webinars, online classes). The majority are going outside every day, with walking being the most common activity. Only a few are restricting their out of home activities to essential tasks (e.g. going to the doctors, pharmacy, getting groceries). Findings suggest that many older adults are engaging in positive coping activities. Assessing coping strategies can give insight into wellbeing.

Switching up How You Get in Your Steps: Daily Activity Diversity and Cognitive Functioning

Active lifestyles are related to better cognitive health. More work is needed, however, to examine whether participating in a variety of daily activities (i.e., activity diversity) has unique importance beyond amount of activity. The current study examined associations between daily activity diversity and cognitive functioning among community-dwelling older adults (N = 313, ages 65-90). Participants completed a cognitive battery, then responded to ecological momentary assessments of their participation in 10 common activity types (e.g., exercise, chores, social visits, volunteering) every 3 hours for 5-6 days, and wore accelerometers to track daily step counts and duration of activity. Multiple regression models revealed that greater daily activity diversity related to higher overall cognitive functioning, executive functioning, memory, and crystallized intelligence. These associations remained significant after adjusting for step count and duration of activity. Findings suggest daily activity diversity has unique importance beyond sheer amount of activity for cognitive health in later adulthood.

Human activities can hinder the breeding of a top avian predator: preliminary results

The Eastern Imperial Eagle (EIE) is a large-sized, globally threatened species with a wide distribution. The species is extremely vulnerable and sensitive to human disturbance and activities in the vicinities of its nests. We analyzed the effect of human disturbance in two territories of Eastern Imperial Eagles from Bulgaria in 2008–2009. We recorded 375 cases of different types of human activity in the vicinities of the two surveyed nests – 60 cases in nest A and 315 in nest B. The most common activity around the studied nests was the passing of light motor vehicles (n=100 cases). Our results highlight that the probability of EIE’s reaction is dependent on the type of activity, distance from the nest and the duration of the activity. However, eagles’ reaction is independent from the number of intruders. We found that with the decrease of the distance to the nest, the reaction progresses and is more acute. We found statistical differences between the distance belts and the majority of alert and flight reactions that were recorded at distances up to 300 m from the nests. We reported that humans walking around nests (mainly hunters, fishermen, tourists, people illegally extracting sand in the close vicinities of the nests) result in a large number of reactions of flight off by the eagles thus, leaving the nest unattended. More research on a large scale on this topic is needed including more accurate measures to address human disturbance in EIE territories. The findings will be applied to ensure higher breeding rates and species conservation.

Art Museums as Institutions for Flourishing

Visiting art museums is a common activity that a wide variety of people choose to engage in for many reasons. Increasingly, communities, nations, and societies are turning to art museums as institutions to contribute to flourishing (i.e., reducing ill-being factors, such as depression, and increasing well-being factors, such as feelings of belonging). In this paper, we review the existing psychological literature examining art museum visitation and museum program participation and their associations with flourishing-related outcomes. The literature suggests art museum visitation is associated with reductions in ill-being outcomes and increases in well-being outcomes. Additionally, programs targeting flourishing outcomes in clinical or at-risk populations (e.g., people living with dementia, older adults) show benefits to participants, with visits to art museums being socially prescribed across the globe to address a variety of ill-being conditions. Implications for existing knowledge and avenues for future research are discussed.

Imaginative Interfaces of Malaysian’s Traditional Games as an Indoor Activity

Smartphones and video games are the most common activity among children to pass the time. Nevertheless, the traditional games are still necessities relevant within today generation. Ketingting is a traditional game that is both entertaining and beneficial for the players' mental and physical development. As most people spend most of their time at home during this pandemic, this study proposes an expanding look. It feels like traditional Malaysian games based on new interface design and material. This new attractive approach, it will encourage children to play traditional games as an indoor activity.

People used to measure the product traditionally using tape measure. However, people can take advantages of the virtual reality products such as augmented reality. This study used mixed methodology involving 105 respondents. The augmented reality will have benefit to reduce the cost since the customer have no need to measure traditionally and to increase efficiency to buy the product. Additionally, the customer will have more trust towards the seller. The augmented reality can help user to understand the product and match the product with the user’s surroundings. This augmented reality will potentially grow and adapt to the user needs as the user might explore more with the image projection.

Hormonal and Neurological Aspects of Dog Walking for Dog Owners and Pet Dogs

The hormone oxytocin is involved in various aspects of the relationship between humans and animals. Dog walking is a common activity for dog owners and their dogs. The walk, of course, should be good for the health of the dog as well as its owner. In Experiment I, we assessed whether salivary oxytocin and cortisol in dog owners changed because of walking their dogs. Ten owners walked with their dogs and walked alone. Similar to other previous research, walking with a dog did not significantly change oxytocin and cortisol. Therefore, in Experiment II, we investigated the effect of dog walking on brain noradrenergic and GABAergic neural activity, as indicated by salivary MHPG and GABA, in 14 dog owners. Walking with a dog reduced salivary MHPG compared to walking alone, and MHPG was correlated negatively with GABA. Thus, dog walking activated GABAergic nerves in the brain and suppressed noradrenergic nerves, effectively relieving stress.

Wall thickness determination study for a plastic injection barrell due to the internal pressure

The use of Plastics is a very common activity nowadays, there are many different types of Injection Machines varying in size, the capacity of the material to inject, one of the main machines classifications is due to the injection pressure. One of the things to consider when the designing process is carried out is the factor of safety, this factor helps designers to avoid possible failures in mechanical elements of mechanisms, it provides a safety margin that aims to protect against any unexpected incident. The advantage of Simulation is that allows us to predict the behavior of elements under stress. In the Injection Process, barrels are elements subject to high pressure. This encourages analyzing wall thickness to find a suitable barrel wall thickness. The present study is focused on the design of the wall thickness, seeking reduce machining time that are required when producing the barrels that may be needed and to select the proper commercial barrel size reducing material waste.
