O parâmetro Pro-drop e a aquisição de segunda língua

open access: yesSemina: Ciências Sociais e Humanas, 1988
Within the Government and Binding theory (GB), it is assumed the man is equipped with some innate language structure, Universal Grammar (UG), which contains a set of inviolable principles plus some open parameters which are set by experience.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Influence of TiC and TiN Ceramic Reinforcements on the Microstructure, Thermal Expansion Behavior, and Tensile Properties of Invar 36 Manufactured by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

A comparative syntactic review of null-subject parameter in English and Ịzọn languages [PDF]

open access: yesJournal of Languages and Culture, 2016
The theory of universal grammar relies predominantly on the biolinguistic concept of natural endowment and innate knowledge of the general principles of language. It postulates that all humans are naturally endowed with the general rules and configurations of language and to this extent, all natural languages have similar structural features.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

open access: yesAdvanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

On L2 Clustering and Resetting the Null Subject Parameter in L2 Spanish : Implications and Observations

open access: yes, 2007
In this article, along with others, we take the position that the Null-Subject Parameter (NSP) (Chomsky 1981; Rizzi 1982) cluster of properties is narrower in scope than some originally contended.
