title: Nanostructured Active Fiber for Mode-Locked and Q-Switched All-Fiber Laser Systems

description: Mode-locked and Q-switched all-fiber lasers using nanostructured core silica fiber are demonstrated. A novel active fiber has been developed, consisting of a collection of discrete nanorods doped with ytterbium and erbium within an aluminosilicate matrix. The arrangement of nanorods within the fiber core dictates the spatial distribution of amplification and refractive index, enabling the tailored design of the fiber's modal characteristics and dispersion properties. We demonstrate that the employed pumping strategy, which involves stimulating Yb3+ ions situated in nanorods and leveraging a non-radiative energy transfer from Yb3+ to Er3+ ions in distinct nanorods, is effective. This approach facilitates efficient laser performance comparable to fibers with a continuous dispersion of active ions throughout the core. The femtosecond mode-locked pulse at wavelength of 1560 nm, featuring a bandwidth of 5.2 nm, a pulse duration of 860 femtoseconds, and an RF spectral purity with an extinction ratio of 80 dB has been successfully obtained. These results underscore the potential of the nanostructured core fiber concept as an active medium in ultrafast, all-fiber devices.

title: Dual Band Active Nanostructured Core Fiber for Two-Color Fiber Laser Operation

description: We present the experimental verification of a new type of an active nanostructured fiber devoted to simultaneous laser emission at two wavelengths: 1040 nm and 1534 nm in the fundamental mode. The fiber core is formed with two types of nanorods made of a phosphate glass doped with either Yb3+ or co-doped with Yb3+/Er3+ ions, respectively. A distribution of the nanorods in the core allows to control relative gain and modal properties of the fiber at both wavelengths and to maintain the single mode performance with a high quality beam generated in a single fiber core. The double-cladding fiber structure allows efficient excitation with a single 975 nm diode pump laser. As a proof-of-concept we demonstrated an active fiber with 15 μm core diameter composed of 6649 nanorods with an individual diameter of 160 nm. The fiber was used in a laser setup. The laser operation was verified for simultaneous two-color laser generation at output power levels of 0.78 W and 0.42 W with slope  efficiency of 23.0% and 9.8% at 1040 nm and 1534 nm, respectively.

title: Damage Tolerance of Aerospace Alloys at Cryogenic Temperatures

description: The decarbonisation of aviation will not be possible without exploring alternative fuels such as liquid hydrogen, and as a result, development of new fuel systems is essential. These system components require exceptional strength and toughness over large temperature ranges, reaching as low as 20 K, necessitating the exploration of strength, fracture toughness, and deformation mechanisms of current aerospace alloys at these temperatures. A series of offline and online uniaxial tensile and compact tension C(T) tests of SS321, S80 and Inconel 718 will explore how strengths and fracture toughnesses of these alloys change with temperature, as well as whether any strain- or temperature-induced phase transformations occur. Based on prior beamtime and resonant ultrasound spectroscopy data, it is expected that yield and ultimate strengths of all alloys will increase at 20 K compared to room temperature, and fracture toughness will decrease for SS321 and S80, while increasing for Inconel 718. S80 is expected to have limited strain-induced phase transformation; temperature- and strain-induced phase transformations are expected for SS321, and twinning is predicted as a deformation mechanism in Inconel 718. Such strength, fracture toughness and deformation mechanism probing has not been previously measured for SS321, S80 and Inconel 718, and as such we expect novel results offering insights into the viability of these alloys in liquid hydrogen fuel systems.

title: <b>Pathology and molecular diagnosis of Marek’s disease virus in chickens in Nigeria</b>

description: Marek’s disease, caused by Marek’s disease virus (MDV) serotype 1, is an economically important neoplastic disease of poultry. Diagnosis of this disease is usually based on clinical signs, post-mortem lesions, and diagnostic tests like cytology, histopathology, and molecular-based methods. However, there might be a problem of inaccurate diagnosis in Nigeria. Employment of gross pathology, histopathology, immunohistochemistry, Polymerase Chain Reaction (PCR), coupled with sequence analysis, provides a reliable approach to arrive at a precise confirmatory diagnosis of the disease. Therefore, visceral organs, including liver, proventriculus, intestine, spleen, and heart samples, were collected at post-mortem examinations from two pullets suspected of having Marek’s disease. Histopathology and immunohistochemistry, as well as PCR amplification of a 576 bp fragment of the MDV glycoprotein L (gL) gene, and sequence analysis were employed in this diagnostic approach. Histopathological examinations of the liver, heart, and proventriculus showed neoplastic pleomorphic cellular infiltration comprising lymphoblasts, lymphocytes, macrophages, and heterophils, which correspond with the pathology of Marek’s disease. Liver samples were positive for the virus using PCR. Sequence analysis based on phylogenetic tree reconstruction revealed that the positive Marek’s disease virus sequences from this study clustered with Marek’s disease virus serotype 1 sequences retrieved from the GenBank. This approach provides a reliable and precise diagnosis of Marek’s disease in chickens, which is applicable to other avian diseases.

title: A systematic review on the impact of cropping systems on carbon dioxide emissions in semi-arid regions

description: Semi-arid regions are predominantly vulnerable to climate fluctuations and change, which can contribute to higher CO<sub>2</sub> emissions. Therefore, there is a need for sustainable farming practices that mitigate climate change as the demand for food and feed production increases. This study systematically reviewed existing literature on the impact of conservation agriculture on carbon dioxide fluxes in semi-arid regions. Subsequently, a systematic search which adhered Preferred Reporting Items for Systematic Review on two search engines (i.e., Scopus and Web of Science) produced 1312 articles, whereof 31 relevant studies met the inclusion criteria of this paper. The results highlighted that conservation agriculture increases soil organic carbon in semi-arid regions, which further reduce the emission of carbon dioxide. Several studies reported that incorporating legumes into crop rotation systems enhanced carbon sequestration, and subsequently reduced the emission of carbon. Moreover, it has been noted that the type of crop rotation, residue management and tillage practice used in a particular system could influence the reduction of carbon dioxide emissions. However, it was recommended that there is a need for long-term studies on the impact of conservation agriculture in order to understand its positive impact in carbon dioxide fluxes and climate change mitigation. Further research is needed on the long term impact of conservation agriculture on carbon dioxide emissions.
