This paper reviews the key factors influencing the extrusion process in aquafeed and pet food production. The quality of the final product and the operational efficiency of the extruder are largely dependent on factors such as feed formulation, extruder configuration, processing conditions, and equipment settings. This review has a specific focus on how mechanical, hydration and thermal parameters correlate to the output variables. Operational parameters such as temperature, moisture content, and screw speed play significant roles in determining the texture, digestibility, and nutritional value of the extruded feed. This review identifies and discusses the physical mechanisms underlying these factors and highlights areas in the current literature that require further research, particularly in optimizing extrusion conditions to improve both product quality and processing efficiency for aquafeed and pet food production through modeling techniques. • Analysis of the main compositional differences between aquafeed and pet food. • Extensive comparison of parameters between extrusion studies based on a thorough quantitative mapping. • Correlations are drawn between key process parameters and output variables. • Convergence of process knowledge and state-of-the-art modeling techniques.

Abstract There is a growing awareness among UK dermatology professionals to evaluate their practice from a sustainability viewpoint. The publication of the British Society for Dermatological Surgery guidance for skin surgery (2022) and The Journal of Sustainable Dermatology in Practice are positive steps. Our study highlights the hitherto overlooked role of teledermatology in promoting sustainable practices and environmental efficiencies. We are an independent teledermatology service provider across six commissioning zones. We cover 165 National Health Service practices with 1565 registered users. Our consultant-led, ‘first-line’ service uses the principle of Getting It Right First Time to redesign and comprehensively manage the clinical pathway for all dermatology referrals between primary and secondary care for commissioners. Combining proprietary software with rapid access to personalized specialist opinion in a cost-effective, timely manner, we achieved the following demonstrable efficiencies. Between January 2020 and January 2025 we prevented 98 684 patients (77% of 128 419 referrals received) from being referred to secondary care. This resulted in direct cost savings of £8 404 735. We saved 37 538 specialist healthcare hours, equating to 20 years’ full-term appointment, creating a significant and sustainable impact when services are grappling with staff shortages. The most positive outcome was the ‘green impact’ of our service. Our patients saved 115 630 h of travel time, and saved 2 582 066 km in travel distance. Assuming the split between patients taking public and private transport is 50 : 50, the total carbon savings were 344 708 kg of CO2 equivalent (CO2e) (Table). In Britain 88% of passenger kilometres are by cars, vans and taxis. Assuming this split, the true total carbon savings were 416 335 kg of CO2e. Each patient saved between £3.10 (public) and £4.38 (private) in transport costs. A split of 88 : 12 between public and private transport gives total transport cost savings of £417 078. We are honoured to have our environmental and efficiency impact recognized by being awarded the Sustainability Partnership awards 2024 for the Supplier of the Year and Software of the Year. We have also been shortlisted for the HSJ Partnership Award 2025. Our report demonstrates that dermatologists can harness technology and innovation to achieve sustainability impact across the wider patient journey. It also shows that green practices can be assimilated seamlessly within the current scope of work.TableTravel statistics assumptionsAverage distance to hospital7.96 miles or 12.81 km one wayAverage emission per car0.17 kg CO2 equivalent per kmAverage emission for public transport (bus)0.097 kg CO2 equivalent per kmAverage travel time to hospital36.25 minAverage petrol cost151 pence per litreAverage fuel cost per appointment (by car)£1.38

Research results are yielded proving the great potential of renewable and alternative energy sources of the Republic of Tajikistan, including solar energy, equal to 25 billion kW h per year. The limited use of “green energy” will impose to periodic blackouts of electric consumers in the autumn-winter period. For remedy the emerging lack of energy, a more complete idea of the potential of solar energy is required. The paper provides the estimation of the energy potential of solar radiation in the Pamir regions and the south of Tajikistan. The mathematical model for definition of maximum value of the azimuth angle for the Pamir region is presented. Expressions for an assessment of functioning of two systems and increments of solar radiation and energy potential, by taking into account duration of daylight are offered. Measurements and calculations of monthly, seasonal and annual levels of solar radiation were performed based on the use of two technical systems. It was shown that the energy efficiency of the dual axis solar tracker (DAST) significantly exceeds the efficiency of the static solar system (SSS) especially in the autumn, spring and summer seasons. A comparative analysis of solar energy production and the efficiency of two systems with the use of a solar tracker for a biaxial tracking system and a fixed system is given. It is shown that the annual productivity of the DAST compared with the SSS is on average by 30% higher. In the autumn, the movable system can generate 80% more energy relative to the stationary arrangement of solar panels. Assessment of the solar potential of the regions of Tajikistan proves the feasibility of using this potential as suitable resource for the development of energy, complementing hydrogeneration.

インターネットは，人間のコミュニケーション方法を根本的に変えた。それは知識の共有・相互作用・経済全体を変革させた。今日，我々は次の革命である「Industry Internet of Things（IIoT）」に直面している。見る，聴く，嗅ぐ，味わう，感じる能力を持つことで，無数の機械とコンポーネントが互いに通信し，指示と最適化を行うことができる。IIoTにより，製品の生産の方法は一新される。一方で，ANDRITZは，長年積み重ねた紙パルプ産業における機械や設備の設計・製造技術，豊富なプロセス知識があり，これらを集約し，スマートデジタルソリューションと共に拡大させている。また，過去数年間，ANDRITZはプロセスの最適化に関する豊富なノウハウを蓄積し，主要産業，主に紙パルプの分野の多くのプロジェクトに導入してきた。これは，新設だけでなく既存の機械や設備にも応用できる。今，これらすべての技術やノウハウは，IIoTと共に，ANDRITZの新しいテクノロジーブランドであるOPPの下で統合される。

2015年12月，国連気候変動枠組条約第21回締約会議（COP21）において1997年の京都議定書に代り，パリ協定が採択された。世界の温室効果ガスの排出量を21世紀後半に実質ゼロ都市，世界の気温上昇の目標値を産業革命以前のレベルから2度未満とする，更に，1.5度以下まで抑制することが地球温暖化リスクを減ずるとされ，努力が求められている。日本は，2030年までに，2013年比でCO2を26％削減するという国際公約をしている。紙パルプ産業は，巨大なバイオマス産業であり，低炭素社会に貢献するグリーンエネルギーを創る潜在能力を有する。アンドリッツは，創グリーンエネルギーに寄与する様々な技術を提案している。

Die Anforderungen an Wasserkraftwerke und im Speziellen an Pumpspeicherkraftwerke (PSP-Werk) haben sich durch den verstarkten Ausbau von Windkraftanlagen und Photovoltaikanlagen stark geandert. Die Rahmenbedingungen sowie die Unterscheidungsmerkmale und die Umsetzungsmoglichkeiten moderner Pumpspeicherkraftwerke werden anhand von verschiedenen Andritz Hydro-Referenzen beschrieben und verglichen.

成熟した産業にあっては，増産益を見込みにくいため，大型設備投資，コストのかかる最新技術の導入は抑制される傾向にある。製紙産業では，数多くの多くの抄紙機が稼働している。時代のニーズに合わせ，製造品種の変更，生産ラインの統合・合理化更には工場統合が行なわれると同時に，設備の老朽化対策，効率化，近代化をしなければならない。マシンをより高速化し，生産性を上げると共に，省エネルギー，品質改善，生産コストの低減が重要となる。マシンの高速化に対応するために，マシン下パルパーの能力アップも求められる。既設設備を最大限に有効活用し，より少ないコストで近代化することは，競争力，収益性の観点から重要である。これは，北米，欧州そして日本など先進国に共通の課題である。

今日主流となっているKPパルプ製造用の連続蒸解装置（連釜）は70年の開発の歴史を有する。1940年代，スウェーデンKamyr ABのJohan Richterにより原料チップを安定して連続的に高圧の反応槽に送り込む高圧フィーダー技術が発明され，バッチ釜方式に代わる連釜技術の歴史が始まった。商業用1号機は，日産50トンの規模であったが，現在は，5,000T／D以上のパルプ生産，原料供給としては10,000T／Dの大型連釜が稼働している。70年の間，KP蒸解プロセスに様々な改良開発が，また，改良プロセスの操業を可能にする数多くの機器，装置開発が行われてきた。
