Researchers from the Smithsonian Institution and UF, among others, found that many of the dominant plant families existing in today's Neotropical rainforests — including legumes, palms, avocado and banana — have maintained their ecological dominance despite major changes in South America's climate and geological structure.
The study, which appears this week in the online edition of the Proceedings of the National Academy of Sciences, examined more than 2,000 megafossil specimens, some nearly 10 feet long, from the Cerrejón Formation in northern Colombia. The fossils are from the Paleocene epoch, which occurred in the 5- to 7-million-year period following the massive extinction event responsible for the demise of the dinosaurs.
"Neotropical rainforests have an almost nonexistent fossil record," said study co-author Fabiany Herrera, a graduate student at the Florida Museum of Natural History on the UF campus. "These specimens allow us to actually test hypotheses about their origins for the first time ever."
Herrera said the new specimens, discovered in 2003, also provide information for future studies that promise to provide an even stronger understanding of the plants that formed the earliest Neotropical communities.
Many previous assumptions and hypotheses on the earliest rainforests are based on studies of pollen fossils, which did not provide information about climate, forest structure, leaf morphology or insect herbivory.
The new study provides evidence Neotropical rainforests were warmer and wetter in the late Paleocene than today but were composed of the same plant families that now thrive in rainforests. "We have the fossils to prove this," Herrera said. "It is also intriguing that while the Cerrejón rainforest shows many of the characteristics of modern equivalents, plant diversity is lower."
The site, one of the world's largest open-pit coal mines, also yielded the fossil for the giant snake known as Titanoboa, described by UF scientists earlier this year.
"These new plant fossils show us that the forest during the time of Titanoboa, 58 million years ago, was similar in many ways to that of today," said Florida Museum vertebrate paleontologist Jonathan Bloch, who described Titanoboa but was not part of the rainforest study. "Like Titanoboa, which is clearly related to living boas and anacondas, the ancient forest of northern Colombia had similar families of plants as we see today in that ecosystem. The foundations of the Neotropical rainforests were there 58 million years ago."
Megafossils found at the Cerrejón site made it possible to use leaf structure to identify specimens down to the genus level. This resolution allowed the identification of plant genera that still exist in Neotropical rainforests. With pollen fossils, specimens can be categorized only to the family level.
Researchers were surprised by the relative lack of diversity found in the Paleocene rainforest, Herrera said. Statistical analyses showed that the plant communities found in the Cerrejón Formation were 60 percent to 80 percent less diverse than those of modern Neotropical rainforests. Evidence of herbivory also showed a low diversity level among insects.
The study's authors say the relative lack of diversity indicates either the beginning of rainforest species diversification or the recovery of existing species from the Cretaceous extinction event.
The researchers estimate the Paleocene rainforest received about 126 inches of rainfall annually and had an average annual temperature greater than 86 degrees. The Titanoboa study, which used different methods, estimated an average temperature between 89 and 91 degrees. Today the region's temperatures average about 81 degrees.
Herrera is now comparing fossils from the Cerrejón site to specimens from other Paleocene sites in Colombia to see how far the early rainforest extended geographically. He is also examining fossils from a Cretaceous site to determine differences in composition before and after the extinction event.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

In a statement released this morning, Bob Rhodes, chair of the council�s Downtown Task Force, said rather than endorsing the proposal, the community should use leading local and national architects and developers though an open design process.
The former Downtown Development Authority chairman went on to say in view of the $11.8 million Mayor Alvin Brown has proposed for the project, the council supports a more thorough and inclusive process for re-imagining the riverfront retail venue.
�Community engagement with key stakeholders will also ensure that the Landing provides the type of unique downtown venue that our citizens deserve,� Rhodes said.
He praised the Downtown Investment Authority�s �thoughtful� Business Investment and Development plan recently introduced to City Council.
�As a key component to unlocking the DIA plan, the Jacksonville Landing deserves an equally thoughtful community review process before public dollars are invested,� Rhodes said.
He encouraged the DIA to have a review process to �engage the public and capture the expertise of professionals� to create a Downtown destination that reflects the true nature of the city.
�Public investment in the Landing can only occur when a community engagement process is conducted and an iconic design is completed and presented,� Rhodes said.
The design for the Landing distributed Saturday was prepared by a small group of architects � none local � who specialize in mixed-use developments, Landing partner Toney Sleiman said this morning.
He said he and Brown already have discussed the need for input from local designers and developers and the value of community engagement.
�That�s funny. We�re already working on having a public meeting as soon as we can put it all together,� he said.
Sleiman welcomes more involvement from the design community in creating the final product. He agreed with the council�s position that redeveloping the Landing is critical to Downtown�s future. He welcomed the Civic Council�s involvement.
�I want everybody�s input to make sure what we do is iconic. We need architects and engineers. I want everybody to help,� said Sleiman.
The Civic Council comprises more than 60 members from a range of industries and disciplines.

Westhills community in Langford expands its offerings MICHAEL BERNARD. Project: Lakepoint One. Project location: Langford. Project size: A total of 46 condominiums in a master-planned community on Langford Lake about 20 minutes northwest of Victoria. Studios from 558 square feet. one-bedrooms from 675 to 921 square feet and two-bedrooms from 1,130 to 1,182 square feet. Price: From $199,900 to $469,900. Developer: Westhills Land Corp. Architect: de Hoog & Kierulf Architects. Sales centre: 115 — 957 Langford Parkway. Occupancy: Late 2017. When Jim Grant and his wife decided to retire, the last thing they wanted was to end up in a retirement community where everyone was in the same age group. At the same time, they were looking to become a bigger part of their grandchildren's lives. When they discovered that Westhills Land Corp. was developing a "multi-generational community" on about 500 acres in Langford, about 30 minutes drive northwest of Victoria, they thought they had hit the jackpot. So they decided to create their very own family enclave. "There are three generations of our family in this subdivision," Grant said. "My daughter and her partner are across the street and she is expecting, and my son and his wife, with our grandchild, is around the corner. We don't have to drive anywhere," he said, adding he ''can have an extra glass of wine" and not get into trouble. "We're looking to getting involved looking after the grandchildren," said Grant, who moved from Toronto 18 months ago after selling his electronics manufacturing business there. I see so many people with grandchildren that for geographical reasons, they can only visit once or twice a year. Developing such mixed neighbourhoods, where retired people can live alongside young growing families, was exactly what Westhills had in mind when it began building its master-planned development in 2007, says Westhills' real estate sales and... Plans call for a build-out of up to 5,000 homes. The developer has already built a mix of housing types, including some 500 single-family houses and townhomes and condos, which Sproule says sell as quickly as they are built. And now, Westhills is adding 46 apartment homes in a six-storey building overlooking Langford Lake. If the market cooperates, he said, they could be followed by a 15-storey residential tower, which would be the tallest structure in the region outside of Victoria. It found that this community of 30,000 is the fastest growing in B. C. and fifth fastest in Western Canada. "We are expecting a mix of buyers from people in their late twenties to young families and lots of people who want to stay out here to downsize and retire," Sproule said. The condominium building of concrete, metal and wood-frame construction will feature two floors of commercial office space— including Westhills' own corporate office — with four floors of apartments overhead, ranging from studios to two-bedroom... On top of those will be a roof-top landscaped terrace, with a barbecue kitchen, lounging and seating areas — and a view of Langford Lake. The apartments are designed with open-concept interior floor plans with oversized low-E double-glazed windows overlooking the lake and nearby mountains. Floors are finished in wide-plank laminate in the living areas. Kitchens come equipped with solid quartz countertops, soft-close cabinet drawers in either contemporary high-gloss or natural grained two-toned finish, and a full-height ceramic backsplash. The kitchen appliances, rated Energy Star, are stainless steel with an electric ceramic range, counter-depth refrigerator, over-the-range microwave, and dishwasher. Homes also have stacking washers and dryers, and some units have built-in pantries or high-profile storage cabinets. Bathrooms feature ceramic floors, walk-in frameless showers, undermount sinks in quartz counters, and soaker tubs in some plans. With Langford Lake just steps away, it's not surprising that Lakepoint One provides homeowners with facilities to store kayaks and paddleboards, plus a bike rack for each unit in a secure section of the building's underground parking. Across the street is a new YMCA-YWCA building built.

Story of Willing Beauty
The story of Willing Beauty begins with Bella Weems, who, at 14, founded one of the fastest growing social selling companies in history, Origami Owl®. With the help of her mother, Chrissy, the Weems have become experts at helping women of all ages become social entrepreneurs. Their desire to be a global Force For GoodTM and fulfill their mission of motivating women to reach their dreams took on a broader meaning when they met Christy and Willa, another mother-daughter duo who had founded a better-for-you teen skincare line, willaTM.
The Weems immediately knew a partnership between Origami Owl and willa would be a dream come true: combining their keen social selling know-how with Christy and Willa's skincare expertise would make a difference in the lives of others — not only in the U.S., but around the world. Thus began Willing Beauty.

Don't forget:
A strong and scale-able architecture is important in applications, especially in Mobile Apps. APIs and SDKs are constantly changing, new technology is constantly released, and team sizes are always changing. A solid Onion Architecture can save a development team a lot of time by making it simple to change service implementations, restrict access to certain areas, making logic flow easy to follow, and making testing isolated blocks of code easier.
Some of the important topics this will cover:
In this section, we will talk briefly about building useful tests for our solution, and why the Onion pattern makes it easy to break tests out into individual layers.
In this example, we will add a test project whose purpose it to just test the Business layer within our Infrastructure.
Let's start with by adding a nUnit project to our solution, or by adding the nuget package to a class library. Xamarin has great documentation on this: https://developer.xamarin.com/guides/cross-platform/application_fundamentals/installing-nunit-using-nuget/
In our project, we also want to install MvvmLight, just like in our Client and Platform layers. We will also need to add references to our Domain.Models, Domain.Interfaces, Application.Models, Application.Interfaces, and Infrastructure.Business projects.
In order to test our Infrastructure.Business project, we will need to create mock versions of our Data project. In our test project, we can create Repository implementations with mock data for each set that we need. For example:
public class MockGenericRepository : IGenericRepository { private List _data; public MockGenericRepository() { _data = new List(); } public void Add(T entity) { _data.Add(entity); } public void AddRange(IEnumerable entities) { _data.AddRange(entities); } public Task CommitAsync() { return Task.FromResult(false); // we don't need to explicitly save changes } public Task FindAsync(Func<T, bool> predicate) { var entity =_data.Where(predicate).FirstOrDefault(); return Task.FromResult(entity); } public Task<IEnumerable> GetAsync(Func<T, bool> predicate) { var entities =_data?.Where(predicate); return Task.FromResult(entities); } public void Remove(T entity) { _data.Remove(entity); } }
and MockUserRepository.cs
public class MockUserRepository : MockGenericRepository, IUserRepository { public MockUserRepository() : base() { } }
Now that we have some mock implementations, we can set up our tests against our Business logic.
public class UserBusinessTest { private IUserService _userService; [SetUp] public void StartUpIoC () { ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default); SimpleIoC.Default.Register<IUserService, UserService>(); SimpleIoC.Default.Register<IUserRepository, MockUserRepository>(); _userService = SimpleIoC.Default.GetInstance(); } [Test ()] public async void AddUserTest() { var result = await _userService.CreateUserAsync(new NewUser { Email = "email@example.com", FullName = "Testy McTest" }); Assert.IsNotNull(result.Data); } }
Now we can test against any of the business logic in our application with a mock layer. The same practice can be applied to test any other layer in the solution as well. The data layer can be tested by mocking the business layer, and so on.
Looking back at all of the components of our Onion Architecture, one might think, "Wow, that's a lot of code to do a simple task". It's important to remember that this architecture is not for every project. It's focus is on scalability and testability. If your project has the potential to grow into something quite complicated, with many developers involved, this type of solution might work best for you. However, if you're working on something quick to get out the door, maybe getting right to the point is easier and best for you.
The best parts about the Onion Architecture are its abilities to make drastic changes to tools or services used, without having to rewrite anything but that components implementation as well as making it easy to test individual layers without affecting the others or using real data. It also allows for closer monitoring and management of the codebase; keeping people from making calls directly from one layer to another. The only thing you have to emphasize is, "Are you adding a reference to another project to get something done? If so, you might be doing it wrong".

Some of the important topics this will cover:
In this section, we will look at how to expand our Inversion of Control container with platform specific code. Specifically, we will implement some pieces of the HockeyApp SDK so that we can make calls to it from our Client or Infrastructure layers.
Our example will focus on just Android, but the same principles can be applied to any of the unique platform projects.
First thing we need to do is make sure we also install the MvvmLight nuget package in your Android project, as well as the HockeyApp Xamarin package.
From here, we can go back to our Application.Interface layer and create a new service:
public interface ICrashAnalyticsService { void Initialize(); void GetFeedback(); }
Setting it up generic like this allows us to switch providers from HockeyApp to some other service should that be a need in the future.
Back in our Android project, let's implement the
ICrashAnalyticsServicewith our HockeyApp logic.
public class HockeyAppService : ICrashAnalyticsService { private const string HOCKEYAPP_KEY = "YOUR_HOCKEYAPP_KEY"; private readonly Android.App.Application _androidApp; private readonly Activity _context; public HockeyAppService(Activity context, Android.App.Application androidApp) { _context = context; _androidApp = androidApp; } public void GetFeedback() { FeedbackManager.ShowFeedbackActivity(_context.ApplicationContext); } public void Initialize() { CrashManager.Register(_context, HOCKEYAPP_KEY); MetricsManager.Register(_androidApp, HOCKEYAPP_KEY); UpdateManager.Register(_context, HOCKEYAPP_KEY); FeedbackManager.Register(_context, HOCKEYAPP_KEY); } }
Now we can create an
IoCConfig class specific to our Android project. Because
SimpleIoC uses a singleton for its container, we can register classes in our platform specific classes before our registrations in the Client layer.
public class AndroidIoCConfig { public void RegisterAndroidServices(Android.App.Application application, Activity activity) { var hockeyService = new HockeyAppService(activity, application); hockeyService.Initialize(); SimpleIoc.Default.Register<ICrashAnalyticsService>(() => hockeyService); } }
Don't forget to add a reference to the
Application.Interfaces project in your platform project.
Lastly, let's update our
MainActivity to initialize our
AndroidIoCConfig before we start up the Xamarin.Forms app:
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity { protected override void OnCreate(Bundle bundle) { TabLayoutResource = Resource.Layout.Tabbar; ToolbarResource = Resource.Layout.Toolbar; base.OnCreate(bundle); global::Xamarin.Forms.Forms.Init(this, bundle); InitializeIoC(); LoadApplication(new App()); } private void InitializeIoC() { var container = new AndroidIoCConfig(); container.RegisterAndroidServices(Application, this); } }
Now we can make calls to our
ICrashAnalyticsService from the Client layer, and use the Android specific logic. For example, we can pass the
ICrashAnalyticsService into the constructor of a
ViewModel, and call the
GetFeedback() method to get access to the HockeyApp Feedback view.
public class ExampleViewModel : BasePageViewModel { private readonly ICrashAnalyticsService _crashAnalyticsService; private ICommand _feedbackCommand; public ICommand FeedbackCommand { get { return _feedbackCommand ?? (_feedbackCommand = new RelayCommand(() => { _crashAnalyticsService.GetFeedback(); })); } } }
It's all that simple! The same pattern can be applied to anything that needs to be platform specific.
In the next and final segment, we will look at building mock implementation of our Infrastructure layer and using them to test layers individually in Unit tests.

Some of the important topics this will cover:
In this section, we will look at the code for our actual Xamarin.Forms client implementation along with talking about building other Non-Xamarin clients into our solution, and sharing as much code between them as possible. This are our Client layer, and will include setting up our Views, ViewModels, IoC container, and start up process.
First thing is first, let's build our
ViewModels. These
ViewModels are going to interface with our Application layer by making calls to our defined Service Interfaces that will be injected into the constructors of our
Some things to note: We are using MVVM Light in this example to make our MVVM and IoC easier to get going. So things such as the
ViewModelBase class and the
Set() method are coming from that library. You can choose to utilize a different library, or roll your own pretty easily. In either case, the principles are the same.
Let's first abstract some universal properties into a BasePageViewModel.cs
public class BasePageViewModel : ViewModelBase { private bool _isLoading; private bool _isEnabled; private string _title; private ObservableCollection<string> _errors; public bool IsLoading { get { return _isLoading; } set { Set(() => IsLoading, ref _isLoading, value); } } public bool IsEnabled { get { return _isEnabled; } set { Set(() => IsEnabled, ref _isEnabled, value); } } public ObservableCollection<string> Errors { get { return _errors; } set { Set(() => Errors, ref _errors, value); } } public string Title { get { return _title; } set { Set(() => Title, ref _title, value); } } public BasePageViewModel() { IsEnabled = true; IsLoading = false; } public override void Cleanup() { base.Cleanup(); Errors = null; } }
From here let's make a
ViewModel for each of our pages (in this example, we will just look at one "MainPage")
public class MainPageViewModel : BaseViewModel { private readonly IUserService _userService; private string _bodyTitle; private string _bodyText; public string BodyTitle { get { return _bodyTitle; } set { Set(() => BodyTitle, ref _bodyTitle, value); } } public string BodyText { get { return _bodyText; } set { Set(() => BodyText, ref _bodyText, value); } } private async void Initialize() { IsLoading = true; await Task.Delay(2000); // simulate load time var users = await _userService.GetValidUsers(); if(users?.Data == null || users.Data.Count() == 0) { var user = await _userService.CreateUserAsync(new NewUser { FullName = "Felipe Fancybottom", Email = "email@example.com" }); BodyText = user.Data.Email; BodyTitle = user.Data.FullName; } else { BodyText = users.Data.First().Email; BodyTitle = users.Data.First().FullName; } IsLoading = false; } public MainPageViewModel(IUserService userService) { _userService = userService; Title = "Onion Template"; BodyTitle = "Loading Name"; BodyText = "Loading Email"; Initialize(); } }
Notice how we injected the
IUserService in the constructor, and use that to lazy load some data into our bindable properties. When we create our view and set the
BindingContext to this
ViewModel, we will see the UI automatically update when those do. This example does it async right from the constructor, but you can load your data and set up your initial properties any way you'd like.
The next step is to initialize our Inversion of Control, Dependency Injection, and
ViewModelLocator to tie all our layers together and allow us to automatically set the
BindingContext of our
If it makes sense to you, you can break the IoC set up into a separate project that references all the previous layers. For the sake of simplicity, we are going to do it in the same project as our Xamarin.Forms project.
public class IoCConfig { public IoCConfig() { ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default); } public void RegisterViewModels() { SimpleIoc.Default.Register<MainViewModel>(); } public void RegisterRepositories() { SimpleIoc.Default.Register<IUserRepository, UserRepository>(); // this is where you would change the registration to use a different repository } public void RegisterServices() { SimpleIoc.Default.Register<IUserService, UserService>(); } public void RegisterProviders() { SimpleIoc.Default.Register<IUserDataProvider, UserDataProvider>(); SimpleIoc.Default.Register<ICloudStorageProvider, AzureStorageDataProvider>(); // this is where you would change the registration to use a different provider } public void RegisterStores() { SimpleIoc.Default.Register<IUserStore, UserStore>(); SimpleIoc.Default.Register<IStoreManager, StoreManager>(); } }
The purpose of this class is to wire up our dependencies as well as our actual container for the
ServiceLocator. This example is using SimpleIoc which is packaged with MVVM Light.
Now that we have our other layers glued together, we just need to create our
ViewModelLocator to automatically handle our bindings, then make calls to the
IoCConfig when the
ViewModelLocator is initialized.
public class ViewModelLocator { public MainPageViewModel MainPage { get { return ServiceLocator.Current.GetInstance<MainPageViewModel >(); } } public ViewModelLocator() { var iocConfig = new IoCConfig(); iocConfig.RegisterRepositories(); iocConfig.RegisterProviders(); iocConfig.RegisterServices(); iocConfig.RegisterViewModels(); iocConfig.RegisterStores(); } }
In our constructor, we initialize our IoC, and also provide properties for each of our
ViewModels, so that we can bind it easily in our XAML.
The last two steps here are to add a Resource in our App.xaml to our
ViewModelLocator, and create our Page.
<?xml version="1.0" encoding="utf-8"?> <Application xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="OnionTemplate.App"> <Application.Resources> <!-- Application resource dictionary --> <ResourceDictionary> <vm:ViewModelLocator xmlns:vm="clr-namespace:NAMESPACEOF.VIEWMODELLOCATOR;assembly=YOURPACKAGENAME" x:Key="Locator" /> </ResourceDictionary> </Application.Resources> </Application>
Now that we have our resource, let's create our page and wire up the
BindingContext in our XAML.
<?xml version="1.0" encoding="UTF-8"?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="NAMESPACE.MainPage" BindingContext="{Binding Source={StaticResource Locator}, Path=Main}" Title="{Binding Title}"> <ContentPage.Content> <StackLayout Orientation="Vertical" HorizontalOptions="Center" VerticalOptions="Center"> <Label Text="{Binding BodyTitle}"/> <Label Text="{Binding BodyText}"/> <ActivityIndicator IsRunning="True" IsVisible="{Binding IsLoading}"/> </StackLayout> </ContentPage.Content> </ContentPage>
There is nothing required to write in our code behind (MainPage.xaml.cs) since it is all automatically wired up.
Last but not least, set our page in our App.xaml.cs:
public partial class App : Xamarin.Forms.Application { public App() { InitializeComponent(); MainPage = new NavigationPage(new MainPage()); } }
At this point, we should be able to run the application (assuming that the Xamarin.Forms app is started off in each platform the way the template sets it up).
So we have our Xamarin.Forms implementation. But what about other applications that can't use Xamarin.Forms? Web apps? Xamarin.Mac apps? Cloud apps? WPF?
Here is one of the coolest parts of the entire Onion pattern. We can go ahead and add more projects into our Client layer. These layers can use the same models, interfaces, and in some cases, implementations! For projects where we would need completely different logic, such as a Web App for example, we can implement multiple versions of the Domain and Application layers.
In our web app, we could create another project in the Infrastructure layer (say Infrastructure.WebData) that uses Entity Framework and SQL. Then in our IoCConfig of our Web App, we call to register our Infrastructure.WebData implementations for our Domain.Interfaces.
As long as each project in the Client layer serves the same purpose of configuring Views, and starting up our application with our Inversion of Control, any type of application can live here and follow the same pattern.
The Client layer can also contain abstractions of controls or other utilities that can be referenced by the core Client projects.
In the next segment, we will look at how to integrate our individual mobile platforms, and how to inject custom platform-specific code with some examples using the HockeyApp SDK.

Some of the important topics this will cover:
In this section, we'll start to dive into the code for our infrastructure layers (or at least what is important), including our business logic and data logic.
Let's dive into the data layer.
This layer is our actual implementation of our Domain definitions, so we are going to implement things such as our Repositories, DataProviders, Stores, or anything else that interacts with our data directly.
From our previous post we defined our
IGenericStore +
IUserStore and our
IGenericRepository +
IUserRepository, so now let's implement them.
GenericStore.cs and UserStore.cs
public class GenericStore<T> : IGenericStore<T> { public List<T> Data { get; set; } public GenericStore() { Data = new List<T>(); } } public class UserStore : GenericStore<User>, IUserStore { }
For the sake of just testing data, our store just contains a collection of data, however, this is where you could implement an observable collection, or more complex data types as well.
Now a look at the repositories – Our implementation of our repository is just going to use in-memory storage, but this is a place where you could implement SqlLite, Azure Mobile Tables, or local file storage instead. You could implement all of these easily and just switch out in your
UserRepository which one it inherits! That's one of the biggest bonuses of our Onion Architecture. The github repository demonstrates this well: https://github.com/SuavePirate/Xamarin.Onion/blob/master/src/OnionTemplate/OnionTemplate.Infrastructure.Data/Repositories/UserRepository.cs
GenericMemoryRepository.cs and UserRepository.cs
public class GenericMemoryRepository<T> : IGenericRepository<T> { private readonly IStoreManager _storeManager; public GenericMemoryRepository(IStoreManager storeManager) { _storeManager = storeManager; } public void Add(T entity) { _storeManager.Set<T>().Data.Add(entity); } public void AddRange(IEnumerable<T> entities) { _storeManager.Set<T>().Data.AddRange(entities); } public Task CommitAsync() { return Task.FromResult(false); // we don't need to explicitly save changes } public Task<T> FindAsync(Func<T, bool> predicate) { var entity = _storeManager.Set<T>().Data.Where(predicate).FirstOrDefault(); return Task.FromResult(entity); } public Task<IEnumerable<T>> GetAsync(Func<T, bool> predicate) { var entities = _storeManager.Set<T>()?.Data?.Where(predicate); return Task.FromResult(entities); } public void Remove(T entity) { _storeManager.Set<T>().Data.Remove(entity); } public void RemoveRange(T entities) { } } public class UserRepository : GenericMemoryRepository<User>, IUserRepository { public UserRepository(IStoreManager manager) : base(manager) { } }
That's all we need to define for our data layer for now. Next let's look at our business logic layer and how it interacts with the data layer through references to our domain interfaces.
Our business layer is our implementation of our Application layer. So we are going to implement the
IBaseService and
IUserService we defined in the previous segment:
IBaseService.cs and IUserService.cs
public class BaseService : IBaseService { public BaseService() { } public IEnumerable<string> Validate(object model) { if(model == null) return new List<string> { "Empty model received" }; return null; } } public class UserService : BaseService, IUserService { private readonly IUserRepository _userRepository; public UserService(IUserRepository userRepository) { _userRepository = userRepository; } public async Task<Result<UserTransferObject>> CreateUserAsync(NewUser model) { var errors = Validate(model); if (errors == null) { var entity = model.ToUser(); _userRepository.Add(entity); await _userRepository.CommitAsync(); return new Result<UserTransferObject>(new UserTransferObject(entity)); } return new Result<UserTransferObject>(ResultType.Invalid, errors); } public async Task<Result<UserTransferObject>> FindByIdAsync(int userId) { var entity = await _userRepository.FindAsync(user => user.Id == userId); if (entity == null) { return new Result<UserTransferObject>(ResultType.Failed, "Could not find user with this Id"); } return new Result<UserTransferObject>(new UserTransferObject(entity)); } public async Task<Result<UserTransferObject>> RemoveByIdAsync(int userId) { var entity = await _userRepository.FindAsync(user => user?.Id == userId); if (entity == null) { return new Result<UserTransferObject>(ResultType.Failed, "Could not find user with this Id"); } _userRepository.Remove(entity); await _userRepository.CommitAsync(); return new Result<UserTransferObject>(new UserTransferObject(entity)); } public async Task<Result<IEnumerable<UserTransferObject>>> GetValidUsers() { var entities = await _userRepository.GetAsync(user => !string.IsNullOrEmpty(user?.Email)); return new Result<IEnumerable<UserTransferObject>>(entities?.Select(entity => new UserTransferObject(entity))); } }
The biggest thing to point out is how the constructor for our
UserService takes in an
IUserRepository. Later we will set up our IoC container and inject our actual
UserService so that the logic ties together. Doing this allows us to avoid referencing the Infrastructure.Data layer in our Infrastructure.Business layer which gives us full Separation of Concerns in our layers.
In the next segment, we'll talk about implementing our Xamarin.Forms application, setting up our Inversion of Control and Dependency Injection, and tying it all together.
We'll also look at each of our different platforms and talk about how we can utilize them without using Xamarin.Forms.
Finally, in the last segment, we will talk about how to truly utilize the Onion Architecture to test, pull, and change important pieces of our application without having to touch anything else.
SignalR is a great tool for keeping not only your web applications synced in real-time, but with it's easy to use APIs for clients, it is perfect for use in your mobile applications.
I have some previous posts that are going to help in designing the of an architecture for a cross-platform implementation with SignalR. Take a look at these:
In this scenario, we are going to focus on two major layers of separation within our applications, although you can always add more layers of abstraction if that is your style or preference. Our two layers are the Portable Class Library and Native Client Libraries. This example is going to be using one PCL with all of our shared code, and then individual projects for Windows Phone 8.1, Windows 8.1, Xamarin.iOS, and Xamarin.Android.
In this architecture, we want to focus on sharing as much code as possible. This implies that the only code that should not be in our PCL is code that includes the UI (Note we are not using Xamarin.Forms), updates the UI, or accesses the device's native features (cameras, location, etc). This would include things such as ViewModels if you're using the MVVM pattern (this example is using MVVM Light), Models, Web Request Logic, and even our SignalR Managers.
With that in mind, here are some nuget packages to consider for your PCL:
So let's get started with a simple BaseHubManager to manage our connections. I'm going to follow a basic Inheritance pattern for these managers so that we can share as much of our SignalR code in our Base Manager as possible.
public class BaseHubManager { public HubConnection Connection{ get; set; } public IHubProxy Proxy { get; set; } // The empty constructor should only be used for a basic connection with no specific Hub public BaseHubManager() { Connection= new HubConnection(Constants.BaseUrl); } // Connect to specific Hub public BaseHubManager(string hubProxy) { Connection= new HubConnection(Constants.BaseUrl); Connection.Headers.Add("Authorization", string.Format("Bearer {0}", App.CurrentUser.TokenInfo.AccessToken)); //add access token to authorize Proxy = Connection.CreateHubProxy(hubProxy); } public async Task Start() { await _connection.Start(new LongPollingTransport()); //Add additional shared Start logic } public void Stop() { _connection.Stop(); //Add additional shared Stop logic } public virtual async void Connect() { await this.Start(); //Add additional shared Connect logic } }
Now that we have a solid base, we can easily spin up individual Hub managers to connect to specific Hubs. Below is an example of a HubManager that would connect to the "ChatHub" on your server.
public class ChatHubManager : BaseHubManager { public ObservableCollection<string> Messages{ get; set; } public ChatHubManager () : base("ChatHub") { this.Connect(); } // Send new message to ChatHub public async Task<string> Create(string newMessage) { //establish connection await this.Start(); var message= await Proxy.Invoke<string>("Create", newMessage); return message; } // Get all messages from ChatHub public async Task<IEnumerable<string>> Get() { //establish connection await this.Start(); var messages = await Proxy.Invoke<IEnumerable<string>>("Get")); Messages = new ObservableCollection<string>(messages); return messages; } }
Expanding new HubManagers like this one make it very easy to call server-side methods from our client by simply creating an instance of our Manager and calling our Invoking methods:
var manager = new ChatManager(); var messages = await manager.Get();
Now what about the other side of SignalR – Client methods? There are some things to consider. Most importantly, will your client end points update anything in the UI? This also includes updating ViewModel properties that will cause updates in the UI.
The problem is that the client end point listeners don't stem from any sort of UI action the way that calling a server method might. Thus, it can't run on the UI thread by itself and you would likely run into some sort of Threading Exception.
If you don't need to update the UI at any point from your client listener, consider adding your listeners in your manager with something like this:
public ChatHubManager () : base("ChatHub") { this.Connect(); Proxy.On<string>("newMessage", async data => { //Do something that is NOT on the UI thread } }
One thing that SignalR does wonderfully is give you the ability to add these listeners from anywhere. That includes from your individual client projects that reference your PCL. So, let's look at how to add these kind of requests to our client projects so we can update our UIs.
Let's use a Windows Phone 8.1 project as our example, although the same logic can be applied to any type of project. So we need to add our client listener like we did above, but we also need it to make changes to our UI, which will require tapping into our UI thread. For this case, let's add a ChatSignalingManager to our Windows Phone project that contains a reference to our ChatHubManager in our PCL above:
public class ChatSignalingManager { private ChatHubManager _hubManager; private CoreDispatcher _dispatcher; public ChatSignalingManager (CoreDispatcher dispatcher) { _hubManager= new ChatHubManager (); _dispatcher = dispatcher; InitializeChatEndpoints(); } //Add client end points for the ChatHubManager private void InitializeChatEndpoints() { var newMessage = _hubManager.Proxy.On<string>("newMessage", async data => { await _dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => { // process your UI changes here }); }); // Add additional end points for the ChatHub here } }
Notice the biggest difference in how we handle our end point in our client project versus our PCL. The Dispatcher. In this case, we can pass Windows CoreDispatcher to our constructor, and by calling _dispatcher.RunAsync we are able to execute our process on our UI thread to successfully run code against our UI.
Here is an example of constructing the ChatSignalingManager from the MainPage of a Windows Phone app:
public sealed partial class MainPage : Page { private ChatSignalingManager _signalingManager; public MainPage() { this.InitializeComponent(); this.NavigationCacheMode = NavigationCacheMode.Required; _signalingManager = new ChatSignalingManager (Dispatcher); } }
Hopefully that is enough code to get you started, but feel free to ask more questions in the comments. Just remember to share as much code as possible in your PCL and use your Client Projects to handle updates to your UI and also to utilize SignalR's flexibility and versatility.

Gaia - Earth Goddess; the goddess or personification of Earth in ancient Greek religion, one of the Greek primordial deities.
Gaia, The Earth Mother. I will be diving deeper into Gaia, into She. I feel this is a connection I've been dismissing (when i become scared) but also consciously cultivating. For me Gaia represents my Faith. Which I feel is why at times our connection unsettles me. I have always felt as though I do not believe in any particular religion however always believed in something greater than myself.

This is a super quick entry to update/talk about several new supplies I got recently. I was going to post something else (think video) but my laptop officially died this past Saturday.
Watch me Draw: Tears from the Moon
Say hello to my 2nd Timelapse!
Watch me cut out the whole background with an x-acto knife. A keen and vulgar solution that delivered a new dimension.
Sketchbook Log: April/May
Here are few entries from my sketchbook.
Above is a little study I did inspired by dear Anya. I included jellyfish ghosts (or something).
3 Paper Scrap Watercolours
All of these were done in old watercolour scrap papers I found in my room. I was lucky enough to have saved them 10 years ago. As an update in art tools: I finally bought some Arches paper from Amazon as well as a watercolour paper sketchbook (and a few other supplies). The package arrived last Friday!
Watch me Draw: Vampire
Here's a new piece and my first time lapse video (requested by V Yari Sama on my facebook page, thanks!). I experimented with a new (to me) thing and went with the flow mixing ink into the watercolours.
Sketchbook: A Menina
It's been like forever since I did my last Sketchbook log. This is a small warm up experiment I did on my redbubble sketchbook with watercolours, a ballpoint pen, a pencil colour, jasmine tea and white acrylic paint.
Vision: Pareidolia
I have been working on this short film for a while. Mainly because crashing systems and other vicissitudes got in the way. Anyway, the vision is finally here. This video was born as a celebration to different ways of seeing. Perception is a subject I'm keen on exploring in my work and wish to continue doing so.
Vision: The Mindroom
With this project I wanted to make a personal approach to the essence of a terrible time. I re-visit the past to question and ritualize it. Taking dark emotions that are often neglected into the frontline.
I started this project during one night of May 2013 by taking impromptu pictures of the place and the things that surrounded me.
Two years later (2015) I return and fill the frame with the same spaces, allowing my current mindstate and perception create a visual contrast. Documenting a process.
Vision: Red
Here's a new addition to the characterization series I'm working on where I treat my own skin as a sketchbook.
I create characters based on my drawings and sketches by designing the make-up and styling, as well as the atmosphere in which they live. Finally I take these creatures in front of the camera, where they manifest.
From an impromptu process that I recorded for you (video below), Red was born.
Mobile: As we fade, 2014
After many angering Force Close issues on my Android, I managed to create As we fade. This small series was done using my tablet's camera to take self portraits where I felt vulnerable while being physically covered.
The post-process was done little by little. To keep myself sane, I worked whenever I had the patience to get an error on my tablet. An annoying error that would force me to start it all over again! I was using an old version of the Pixlr app.
During this constricted process I remembered how easy it could've been to create each image in Photoshop, but I kept struggling to blend the pixels with my thumb. Faded into everything, melting into an open space of emptiness yet reaching out.

OSCILLATING ELECTRIC MOTOR Fil e d March 30, 1967 2 Sheets-Sheet 2 5b -1.b -3b -2b 4b 0 10 2b 30 4b s'o' INVENTOR 8 Jean-Claude Logier ATTORNEYS United States Patent US. Cl. 310-36 3 Claims ABSTRACT OF THE DISCLOSURE Oscillating electric motor the stator of which consists of a magnetizable core surrounded by an energizing coil and having two polar pieces extending parallel on either side of said core, the rotor having a permanent magnet pivoted between the polar pieces, these pieces each having a thin, incurved, shoe enveloping the rotor on at least a part of its periphery.
In motors of the type with which this invention is concerned and wherein the rotor is constantly brought back in a neutral position such that the axis of its poles is perpendicular to that passing by the two stator polar pieces, the curve of the couple exerted on the motor and measured as a static function thereof decreases very rapidly as soon as this rotor is moved angularly from its neutral position to bring it into another position out of phase by 90 with respect to the previous one. That is to say, with such a motor in dynamic operation, the angle of deviation of the rotor will be very sensitive to an external resistant couple since the couple exerted on this rotor is really powerful only near its neutral position.
The invention has for its principal object to avoid this drawback and provides an oscillating motor capable of so doing.
Preferably but not exclusively the rotor consists of a strongly anisotropic ferrite block and a maximum air-gap separating the rotor from the polar shoes is of the order of 1.5 mm.
The invention will now be described with reference to the accompanying drawings which represent one embodiment thereof.
FIGURE 1 is a lateral schematic view of the motor according to the invention.
FIGURE 2 is a cross-sectional view taken along line II-II of FIGURE 1.
FIGURE 3 is a graph the curves of which show a variation of the couple exerted on the conventional motor compared with that exerted on a motor according to the invention as a function of the angular displacement of the rotor.
The oscillating motor shown comprises a stator formed by a lamellar core 1, encircled by an electric energizing coil 2, fed with AC current from wires 2a and 2b, and to which are secured two polar pieces 3 and 4 extending parallel on either side of this core (see FIGURES 1 and 2).
Each polar piece 3 and 4 carries on its free part a thin shoe 5, formed of a magnetizable plate having a thickness of about 1 mm. and shaped with a rounded profile the centre of curvature of which corresponds to that of rotor 6 of the motor mounted between said pieces 3 and 4.
The air-gap separating this rotor 6 from the two shoes is of the order of about 1.5 mm.
This air-gap of a relatively considerable size is made possible in the subject embodiment because the rotor consists of a strongly anisotropic ferrite block. In the conventional motors of this type the air-gap is only of the order of 0.2 to 0.3 mm.
Owing to the size of the air-gap possible with the motor of the invention, there does not arise tolerance problems during assembly; moreover, even in the case where certain metallic dusts were to be drawn to the rotor when mounting, they would not cause trouble in the operation of the motor, which is evidently not the case with conventional motors.
Rotor 6 is mounted on a shaft 7 secured in a central opening of this rotor by any suitable means, for example by gluing, and pivoted in a single bearing 8 carried by a support 9, mounted outside the polar pieces 3 and 4 on the side opposite core 1.
The angle of oscillation of the rotor of the motor according to the invention can be determined with precision: this angle in effect is in direct function of the length of the stator shoes enveloping the rotor.
The graph of FIGURE 3 shows for the static operation of an oscillating motor, the variation of the couple acting on its rotor when the same is moved away from its neutral position by a variable angle a.
Curve A relates to an oscillating motor having polar pieces without shoes and having a conventional rotor separated from these pieces by an air-gap of the order of 0.2 to 0.3 mm.
Curve B is that of a motor according to the invention with shoes, ferrite rotor and air-gap of about 1.5 mm.
In order to effect the measurements the result of which is shown on this graph, the winding 1 is fed with a direct current having an intensity corresponding to that of the effective value of the current absorbed during the normal operation of the motor when fed with single phased alternating current.
It is seen that couple C of the motor the characteristic of which is indicated by curve A, decreases abruptly when the angle a varies from 0 to +12 or from 0 to --12. Moreover, for a deviation of the rotor of +45 couple C is practically nil.
On the contrary, in the case of the motor of the invention the curve of which B, reflects the evolution of couple C measured as a static function of the motor, the maximum couple for a deviation of an angle a=0 is less than a maximum couple given by curve A but the couple of this motor decreases only by about 40% for a deviation of 45".
By giving the correct saturation to the polar shoes of this motor, it is even possible to obtain a curve of the couples for static functioning which is practically flat in function of the deviation of the rotor which is translated, during dynamic operation of this same motor, by a maximum reduction of about 20% of the couple.
The conventional type motor is thus very sensitive to an external resistant couple since its couple can become very weak; on the contrary, in the new motor of the invention, the angular deviation is practically independent of such a resistant couple.
-It is also worthy to remark that with a conventional oscillating motor, of the type used for establishing a curve A, this curve is not really symmetrical for angular displacements of the rotor eflected on either side of the neutral axis of the motor only if the air-gap and the rotor are strictly symmetrical.
The least asymmetry thus gives rise to an important deformation of curve A, which is tantamount to saying that if the conventional construction is not made with great care, there will result incorrect operation of the motor.
In the case of an oscillating motor according to the invention, that is to say provided with polar pieces, a ferrite rotor and having an air-gap much larger, there is noticed practically no interfering asymmetry.
3 While I have described a preferred embodiment of my invention, it will be understood that various other modifications may be made without departing from the spirit thereof. I wish therefore to be limited not by the foregoing description but, on the contrary, solely by the claims granted to me.
What is claimed is:
1. An oscillating electric motor including (a) a permanent magnet rotor mounted for angular oscillation about an axis and magnetized in a direction transverse to said axis,
(b) an electromagnetic stator having a pair of spaced legs extending longitudinally of said axis with respective pole sections at first ends thereof on opposite sides of said rotor and a transverse section joining said legs nearthe other ends thereof,
() and a coil encircling said transverse section for A-C energization to produce oscillation of said rotor,
(d) said rotor having a neutral position in which the magnetic poles thereof lie approximately midway between the sides of said pole sections,
wherein the improvement comprises (e) shoe portions of magnetizable material extending circumferentially of said rotor on each lateral side of said pole sections for substantially the full length of the permanent magnet rotor,
(f) the thickness of said shoe portions being less than 4 the air gap between said'pole sections and the rotor and being substantially less than the radial dimension of said pole sections.
2. An oscillating electric motor according to claim 1 including a pair of shoes of magnetizable material on the inner faces of said pole sections, respectively, and extending beyond the lateral sides thereof to form said shoe portions.
3. An oscillating electric motor according to claim 1 in which said permanent magnet rotor is of anisotropic ferrite material.
