Unveiling recharge sources and dominant processes for alluvial aquifers using hydrochemical and isotopic techniques

open access: yesKuwait Journal of Science
The study deals with the hydrochemistry (EC, DO, pH, HCO3–, SO2-4, Cl−, Ca2+, Mg+, Na+, and K+) and isotopic studies (18O, 2H, and 3H) of the groundwater of the Thal Doab, between River Indus and Jhelum, to delineate the sources of recharge and quality ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

open access: yesAdvanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Decompression of inferior alveolar nerve: case report comment [PDF]

open access: yes, 2011
Paresthesia as a result of mechanical trauma is one of the most frequent sensory disturbances of the inferior alveolar nerve. This case report describes surgical treatment for paresthesia caused by a compressive phenomenon within the mandibular canal ...

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

open access: yesAdvanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

Effect of the administration of lyophilized bovine adenohypophysis in broilers

open access: yesRevista Ingenio, 2012
Freeze-dried bovine adenohypophysis arises as a promoter of biological growth in broilers that seeks as an alternative the improvement of zootechnical parameters in this poultry farm, with the optimization of factors such as weight gain, feed conversion,

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Use of granulands for analysis of social class [PDF]

open access: yes
In this paper, an analytical tool enabling the analysis of social stratification is proposed. The classical scheme for scaling consisting of two stages, conceptualisation and operationalization, is modified by the use of the concept of granulation ...

Movement and habitat use of two aquatic turtles (\u3cem\u3eGraptemys geographic\u3c/em\u3e and \u3cem\u3eTrachemys scripta\u3c/em\u3e) in an urban landscape [PDF]

open access: yes, 2008
Our study focuses on the spatial ecology and seasonal habitat use of two aquatic turtles in order to understand the manner in which upland habitat use by humans shapes the aquatic activity, movement, and habitat selection of these species in an urban ...
