Summary
This study evaluated diet and nutrition apps on the Google Play Store. Diet apps generally received higher ratings and were more frequently updated than nutrition apps.
Area of Science:
- Digital Health
- Mobile Health Applications
- Health Informatics
Background:
- The proliferation of mobile health (mHealth) applications presents both opportunities and challenges for users seeking to manage their diet and nutrition.
- App stores, such as the Google Play Store, offer a vast array of diet and nutrition applications, but their quality and features vary significantly.
Purpose of the Study:
- To systematically evaluate the characteristics and features of diet and nutrition applications available on the Google Play Store.
- To compare the attributes of diet-specific applications versus general nutrition applications.
Main Methods:
- A comprehensive search of the Google Play Store was conducted in August 2017 using the terms 'diet apps' and 'nutrition apps'.
- The top 50 applications from each search term were initially identified, duplicates were removed, and a comparative analysis was performed on the remaining 72 unique applications.
Main Results:
- A total of 86 free diet and nutrition apps were identified, with most (94%) suitable for all age groups.
- Diet apps (average rating 4.4) were rated slightly higher than nutrition apps (4.3) and were more likely to be recently updated (72% vs. 66%).
- Diet apps were also more likely to include in-app purchases (36% vs. 19%), though apps without in-app purchases showed a slightly higher average rating.
Conclusions:
- A need exists for a centralized platform to systematically assess the effectiveness of health-related applications.
- Further research should focus on improving app store design and app presentation to better guide users in selecting reliable diet and nutrition tools.

02:11The Roles of Bacteria and Fungi in Plant Nutrition
47.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

01:12Energy Stored in a Capacitor
4.8K
When an archer pulls the string in a bow, he saves the work done in the form of elastic potential energy. When he releases the string, the potential energy is released as kinetic energy of the arrow. A capacitor works on the same principle in which the work done is saved as electric potential energy. The potential energy (UC) could be calculated by measuring the work done (W) to charge the capacitor.

The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...

A parallel plate capacitor, when connected to a battery, develops a potential difference across its plates. This potential difference is key to the operation of the capacitor, as it determines how much electrical energy the capacitor can store.
By integrating the equation that relates voltage and current in a capacitor, one can derive an equation for the voltage across the capacitor at any given time. This equation is crucial in understanding and predicting the behavior of capacitors in...

01:16Energy Stored in Inductors

An inductor is ingeniously crafted to accumulate energy within its magnetic field. This field is a direct result of the current that meanders through its coiled structure. When this current maintains a steady state, there is no detectable voltage across the inductor, prompting it to mimic the behavior of a short circuit when faced with direct current.
In terms of gauging the energy stored within an inductor, it is equivalent to the integral of the power delivered at every individual moment, all...
