Cage culture is an utilisation of existing water bodies with little or no economic costs.
The selection of a suitable site for a cage farm is indispensible for their effective function,
particularly in relation to proper water quality within the cage and reduced environmental
impacts around the cage and for the economic viability of the cage farm. The natural
tolerance of species should be studied for assessment of suitable site

4-Chloro-N′-[(Z)-4-(dimethylamino)benzylidene]benzohydrazide monohydrate
In the title compound, C16H16ClN3O·H2O, the dihedral angle between the two aromatic rings is 44.58 (11)°. The N atom of the dimethylamino group adopts a pyramidal configuration. In the crystal structure, molecules are linked into a two-dimensional network parallel to the (001) plane by intermolecular N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds involving the water molecule and C—H⋯Cl hydrogen bonds. In addition, C—H⋯π interactions are observed
Blood pressure intervention levels in preterm infants : pilot randomised trial
OBJECTIVE: To examine the feasibility of a trial allocating different blood pressure (BP) intervention levels for treatment in extremely preterm infants. DESIGN: Three-arm open randomised controlled trial performed between February 2013 and April 2015. SETTING: Single tertiary level neonatal intensive care unit. PATIENTS: Infants born <29 weeks' gestation were eligible to participate, if parents consented and they did not have a major congenital malformation. INTERVENTIONS: Infants were randomised to different levels of mean arterial BP at which they received cardiovascular support: active (<30 mm Hg), moderate (<gestational age mm Hg) or permissive (signs of poor perfusion or <19 mm Hg). Once this threshold was breached, all were managed using the same treatment guideline. BP profiles were downloaded continuously; cardiac output and carotid blood flow were measured at 1 day and 3 days, and amplitude integrated EEG was recorded during the first week. Cranial ultrasound scans were reviewed blind to study allocation. MAIN OUTCOME MEASURE: Inotrope usage and achieved BP. RESULTS: Of 134 cases screened, 60 were enrolled, with mean gestation 25.8 weeks (SD 1.5) and birth weight 817 g (SD 190). Invasively measured BP on the first day and inotrope usage were highest in the active and lowest in the permissive arms. There were no differences in haemodynamic or EEG variables or in clinical complications. Predefined cranial ultrasound findings did not differ significantly; no infants in the active arm had parenchymal brain lesions. CONCLUSION: The BP threshold used to trigger treatment affects the achieved BP and inotrope usage, and it was possible to explore these effects using this study design. TRIAL REGISTRATION NUMBER: ISRCTN83507686
A systematic review on the determinants of customer relationship quality in agile projects in the IT industry: a social exchange theory perspective
In recent decades, Sri Lanka's IT industry has thrived, contributing significantly to economic development. Effective project management, especially using Agile methodologies, has been key to this success. Agile, with its customer-centric and flexible approach, has replaced traditional models like Waterfall, emphasizing frequent software delivery and active customer engagement. Customer Relationship Quality is vital for project success, fostering customer satisfaction and loyalty. Agile methods prioritize strong customer relationships through collaboration and customer involvement. However, challenges persist in Sri Lanka due to a lack of understanding among software companies regarding factors crucial for maintaining robust customer relationships, leading to project failures and dissatisfied customers. To address these challenges, this paper undertook a systematic literature review, focusing on Agile project management, Social Exchange Theory, and Customer Relationship Quality. The research question was, "What factors influence Customer Relationship Quality in Agile IT Projects, from a Social Exchange Theory perspective?". Peer-reviewed articles, conference papers, and book chapters from 2012 to 2023 were reviewed, emphasizing human-centered aspects. The study uncovered an overlap in factors affecting both Agile project success and Customer Relationship Quality, highlighting the pivotal role of Customer Relationship Quality. Common factors, such as communication, culture, team capability, and commitment, were identified as crucial elements for project success and relationship quality. Future research should explore these shared factors in-depth to enhance Agile project success and Customer Relationship Quality. This research contributes to a deeper understanding of Agile project management, customer relationships, and their interconnectedness, emphasizing the need for further studies in this evolving field
Emergent chiroptical properties in supramolecular and plasmonic assemblies
This tutorial provides a comprehensive description of the origin of chiroptical properties of supramolecular and plasmonic assemblies in the UV-visible region of the electromagnetic spectrum. The photophysical concepts essential for understanding chiroptical signatures are presented in the first section. Just as the oscillator strength (a positive quantity) is related to absorption, the rotational strength (either a positive or a negative quantity) defines the emergence of chiroptical signatures in molecular/plasmonic systems. In supramolecular systems, induced circular dichroism (ICD) originates through the off-resonance coupling of transition dipoles in chiral inclusion complexes, while exciton coupled circular dichroism (ECD) originates through the on-resonance exciton coupling of transition dipoles in chiral assemblies resulting in the formation of a bisignated CD signal. In bisignated ECD spectra, the sign of the couplet is determined not only by the handedness of chiral supramolecular assemblies, but also by the sign of the interaction energy between transition dipoles. Plasmonic chirality is briefly addressed in the last section, focusing on inherent chirality, induced chirality, and surface plasmon-coupled circular dichroism (SP-CD). The oscillator strength is of the order of 1 in molecular systems, while it becomes very large (104-105) in plasmonic systems due to the collective plasmonic excitations, resulting in intense CD signals, which can be exploited for the design of plasmonic metamaterial platforms for chiral sensing applications.

N′-[(E)-1-Phenylethylidene]benzohydrazide
The title compound, C15H14N2O, crystallized with two independent molecules in the asymmetric unit. Both molecules are non-planar and have an E configuration with respect to the C=N bond. The dihedral angles between the two benzene rings are 11.1 (2)° in one molecule and 12.40 (19)° in the other. In the crystal structure, the molecules are linked by N—H⋯O hydrogen bonds and weak C—H⋯O interactions into infinite one-dimensional chains along [1 0 0]. The crystal structure is further stabilized by N—H⋯O hydrogen bonds, weak C—H⋯O and very weak C—H⋯π interactions
4-Amino-3-{1-[4-(2-methylpropyl)phenyl]ethyl}-1H-1,2,4-triazole-5(4H)-thione
In the title triazole compound, C14H20N4S, the dihedral angle between the triazole and benzene rings is 83.29 (11)°. The methine H atom and two methyl groups of the isobutyl group are disordered over two sites with occupancies of 0.684 (9) and 0.316 (9). In the crystal structure, N—H⋯S hydrogen bonds link the molecules into chains running along the b axis. These chains are cross-linked into a two-dimensional network parallel to the ab plane by C—H⋯S hydrogen bonds
