To overcome the limitations associated with studying the interactions between bacterial communities (BCs) and cyanobacteria in natural environments, we compared the structural and functional diversities of the BCs associated with 15 non-axenic cyanobacterial strains in culture and two natural BCs sampled during cyanobacterial blooms. No significant differences in richness and diversity were fou...

Biochars (BCs) are considered as ecofriendly and multifunctional materials with significant potential for remediation of contaminated water soils, while engineered biochars (E-BCs) enlarged surface areas abundant functional groups can perform even better in environmental remediation. This review systematically summarizes the key physical chemical properties BCs that affect their pollutant sorpt...

Twenty Simmental x Angus, half-sibling, postpubertal heifers (initial BW of 443 +/- 9 kg) were allotted randomly to 2 treatments to evaluate if initial BCS affects how heifers respond to energy restriction and repletion. Dependent variables of interest were changes in BW, BCS, and reproductive status [determined by concentrations of serum progesterone (P(4))]. Empty body composition (EBC) was c...

Superconductivity is one of the historical landmarks in condensed matter physics. Since Onnes found out the fact that the electrical resistivity of mercury drops to zero below the temperature 4.2K in 1911, the zero electrical resistivity is observed in many metals and alloys. Such a phenomenon is called superconductivity, and the magnetic properties of superconductors as well as their electric ...

Automatic estimation of the amount of trash, such as branches and leaves, collected by a mechanical citrus harvester during harvesting eliminates problems in the processing plants with handling diseased leaves and fruit. A machine vision system was developed to estimate the amount of trash collected by a citrus canopy shake and catch harvester by acquiring and analyzing the images of the harves...

In recent times, vibration based energy harvesting has drawn attention of many researchers worldwide. This is due to advancement in Microelectromechanical (MEM) devices and wireless sensors with power requirements in range of microwatts-milliWatts; hence vibration energy sources have promising potentials for such demands. Thus, many attempts were made by researchers to develop different system ...

Here, we report a stable and predictable aero-elastic motion in the flow-driven energy harvester, which is different from flapping and vortex-induced-vibration (VIV). A unified theoretical frame work that describes the flutter phenomenon observed in both "stiff" and "flexible" materials for flow driven energy harvester was presented in this work. We prove flutter in both types of materials is t...

Harvesting mechanical energy from human motion is an attractive approach for obtaining clean and sustainable electric energy to power wearable sensors, which are widely used for health monitoring, activity recognition, gait analysis and so on. This paper studies a piezoelectric energy harvester for the parasitic mechanical energy in shoes originated from human motion. The harvester is based on ...

The objective of this study was to confirm the relationship among body condition score at the time around parturition, milk yield in subsequent lactation, reproductive efficiency and BCS development in Czech Fleckvieh dairy cows. The BCS and milk yield were measured once a month and the cows were divided into groups according to their BCS before and after calving. Next, data from the database o...

The aim of the study was to explore genetic relationship among milk yield, body condition score (BCS) and pregnancy status (PR) in Italian Holstein cows using a recursive effects model. Two recursive models and a multiple-trait model were compared in four different subsets of data. The antagonistic effect of milk yield on BCS and PR was confirmed, as well as the positive relationship between BC...
