Field trials were conducted at Tambul in the High Altitude Research Centre in Papua New Guinea Highlands. The trials evaluated four varieties of potato, two of which are resistant to Potato Late Blight disease and bred by the International Potato Centre (E2, E24), Kumdi and PNG industry variety, Sequoia against three planting densities (PD) and three fertilizer rates (FR) in a 4x3x3 factorial design. Trials were replicated three times and repeated in three seasons at three different sites. Stem height of E24 was significantly (P<0.05) higher followed by E2, Kumdi then Sequoia respectively. Marketable and total tuber number plant-1 was significantly (P<0.05) influenced by varieties and treatments especially PD. All varieties performed high marketable and total tuber number plant-1 at moderate to low PD. Optimum marketable and total tuber yield (t ha-1) of E2, Kumdi, Sequoia and E24 were observed at high PD and moderate to high FR. High seed tubers were observed at high density and low to moderate FR. E2 and Kumdi had appropriate genetic traits resistant to PLB disease and natural aptitude to influence tall stem height cultivated using high PD and moderated to high FR resulted in healthy crop development and high yield performance.

Ratio « number of males on number of females » for the mass production of Sar...Innspub Net
The appropriate proportion of male and female parents that give a highest number of juveniles is a major concern in tilapia culture Sarotherodon melanotheron due to the oral incubation by males. A study of the ratio “number of males to number of females” on fingerlings production has been performed in order to determine the optimal ratio for S. melanotheron. Five ratios were tested : R1 (1 male to 2 females), R2 (1 male to 3 females), R3 (2 males to 2 females), R4 (2 males to 4 females) and R5 (2 males to 6 females). The experimental device consists of five concrete tanks (1m x 1m x 60cm) filled to 2/3, about 0.17m3 of water. The fish are fed three times a day with a diet containing 35% crude protein. Once a week, the fertilized eggs are collected and incubated in a tank. The hatching rate and larval growth are followed. The experiment was duplicated and lasted 6 weeks to harvest eggs and 40 days to track the growth of larvae. The results show that the number of egg laying is significantly different from a ratio to each other (p ˂ 0.05) and increases with the number of males and females. The highest number of egg laying is obtained with R5 ratio “2 males to 6 females” that seems best for the mass production of juveniles of S. melanotheron. These results provide a basis for the intensive production of S. melanotheron for the aquaculture development in lagoon.

The study was conducted to assess the comparison at the production performance and profitability between mixed-sex and mono-sex tilapia reared in cage culture. The experiment was carried out with two treatments and each was represented by six replicates for a period of 99 days in 12 cages each with the size of 1.5m3 (1.5m×1m×1m) situated in a pond. In the first treatment, six cages of mixed-sex tilapia and in the second treatment, 6 cages of mono-sex male tilapia were stocked. After 99 days of the culture period, mono-sex tilapia attained a significantly higher mean final weight of 189.67 gm ± 19.142 in comparison to mixed-sex tilapia which was 167.15 gm ± 13.297. However, there was no significant difference in food conversion ratio, specific growth rate, and survival rate between the treatments at the end of the study. The benefit-cost ratio was calculated as 1.47:1 and 1.59:1 for mixed-sex and mono-sex male tilapia respectively. The study revealed that there was no significant difference in individual weight, biomass, and the gross yield of tilapia between two treatments up to 72 days of the culture period. The comparative study suggested that within 2.5 months of the culture period, mixed-sex tilapia can be cultured successfully and could be used as an alternative source to the general people who usually avoid the consumption of hormone-treated fish.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Empat anakan strain nila yang terpilih (Oreochromis niloticus) dievaluasi untuk melihat
produksinya di tambak air payau dalam rangka menyediakan alternative produksi untuk
para pembudidaya udang di Indonesia. Strain yang digunakan dalam percobaan ini adalah
nila GIFT (Genetic Improvement of Farmed Tilapia), Nirwana, Merah, dan anakan hasil
persilangan GESIT(Genetically Enhanced Supermale Indonesian Tilapia) dan GIFT . Nila
dibudidayakan di dalam hapa pada tambak payau tradisional di Desa Salenrang,
Kecamatan Bontoa, Kabupaten Maros. Dua puluh empat hapa, masing-masing 4 m x 10 m,
diletakkan dalam 4 deretan, yang memungkinkan untuk rancangan acak kelompok. Dari
prespektif produksi, melalui analisis REML Strain Merah berperforma terbaik, dengan tingkat
pertumbuhan yang konsiten lebih tinggi dari ketiga strain lainnya (P<0,001), namun karena
harga nila merah rendah di kedua pasar uji (di Provinsi Sulawesi Selatan dan Banda Aceh).
Nilai produksi nila merah lebih rendah dibandingkan nila hitam. Dari empat strain yang
diujikan strain hasil persilangan GESIT X GIFT memberikan keuntungan terbaik.
Kelangsungan hidup relative rendah untuk semua strain (39-48%) dan pertumbuhan pada
masa akhir pemeliharaan rendah (SGR <1,5% per hari), karena terjadi penurunan kualitas
air. Salinitas rendah (1 ppt) pada awal pemeliharaan,akan tetapi meningkat terus hingga 21
ppt di akhir pemeliharaan (125 hari). Berdasarkan hasil percobaan kami menyarankan
kepada seluruh pembudidaya untuk membudidayakan anakan hasil persilangan GESIT X
GIFT. Program pemuliaan nila yang toleran terhadap kadar garam terlalu focus pada nila
merah, dan itu mungkin tidak cocok untuk produksi tambak payau di Indonesia, karena nila
hitam lebih disukai pasar.

2. PERFORMANCE OF FOUR STRAINS OF NILE TILAPIA (Oreochromis niloticus) IN
BRACKHISWATER PONDS
Abstract
Four selectively-bred strains of Nile tilapia (Oreochromis niloticus) were evaluated for
production in brackishwater ponds to provide an alternative production option for shrimp
farmers in Indonesia. The strains used in the trial were: Genetic Improvement of Farmed
Tilapia (GIFT), Nirwana, Red, and a Genetically Enhanced Supermale Indonesian Tilapia
(GESIT) × GIFT cross. Tilapia were cultured in hapa nets in a ‘traditional’ brackishwater
pond in Salenrang village, Bontoa sub-district, Maros district, South Sulawesi. Twenty-four
hapa nets, each 4 m × 10 m, were constructed in six rows of four hapas, allowing a
randomised block design. From a production perspective, the Red strain performed best, with
consistently higher growth rates than the other three strains throughout the trial (REML
analysis, P<0.001). However, because ‘red’ tilapia bring lower market prices in both our test
markets (South Sulawesi and Aceh provinces), the value of production of the Red tilapia
strain was lower than the ‘black’ tilapia strains. Of the four strains, the GESIT×GIFT cross
provided the best economic return. Survival was relatively low for all four strains (39–48%)
and growth during the later stages of the trial was poor (SGR <1.5 %/day), due to water
quality deterioration in the pond. Salinity was low (1 ppt) at the beginning of the trial but
rose steadily due to evaporation and reached 21 ppt by the end of the trial (125 days). Based
on the results of this trial we recommend that farmers culture GESIT or GESIT×GIFT cross
tilapia. Selective breeding programs for saline-tolerant tilapia tend to focus on red tilapia
strains, and these may be unsuitable for brackishwater production in Indonesia due to the
widespread market preference for ‘black’ strains of tilapia.
