Both contributing to the Alliance collective defence and the need of active participation in allied multinational operations of crisis management seems impossible without other countries’ forces co-operation, logistic co-operation including. This, in turn, requires reaching and maintaining an appropriate range and level of interoperability. Hence wherever certain types of armament are used by more than one country’s forces, the Alliance recommends a co-ordinated approach to logistics supplies. Special capabilities are created by the consolidation of supply assets and needs to maintain them in use. In case of Polish Air Force, one of the measures facilitating to reach this goal is Aircraft Cross-servicing (ACS). Its main aim is to increase NATO Rapid Reaction Forces flexibility in the area of base changing, recreating deployment effectiveness, preparing for the next take-off and accomplishing tasks by tactical air force by gaining a possibility to conduct operations from airports other than main operational bases and new base airfields.

The use of the anterior technique for abdominal wall components separation combined with “onlay” alloplasty (ACST + onlay) in giant incisional hernias (IH) may pose a surgical challenge as it does not exclude increased intra-abdominal pressure (IAP) and the occurrence of abdominal compartment syndrome (ACS). There remains a high incidence of surgical site complications. In our view, the use of intra-abdominal alloplasty combined with anterior separation of the anterior abdominal wall components (ACST + IPOM) will contribute to the improvement of surgical outcomes in giant IH. Purpose: to improve the results of surgical treatment of giant IH using ACST + IPOM. Materials and methods: Analysis of surgical treatment of 164 patients with giant IH aged 30 to 75 (mean age 54.7 ± 3.3). Depending on the surgery, the patients were divided into two groups. Group I (82 patients) consisted of patients who underwent our modified technique, including ACST + IPOM. The surgery in group II (82 patients) involved ACST + onlay. Results and discussion: As compared with ACST + onlay, ACST + IPOM surgery contributes to a significantly reduced incidence of ACS [6.1% (group II) versus 0 (group I), (p <0.05)], seroma [25.6% versus 7.3%, p <0.05], surgical site infection (SSI) [4.9% versus 2.4%, p> 0.05], meshoma [3.7% versus 0] and hernia recurrences [6.5% versus 1.6%, p> 0.05]. Conclusions: IAP value equal or exceeding 9.1 mmHg (1.2 kPa) during surgery in approximated rectus muscles is prognostic for ACS occurrence and requires intraoperative preventive measures. Utilization of ACST + IPOM in giant IH ensures an optimal abdominal cavity volume without a substantial increase in IAP and reduces the probability of ACS, whereas the use of ACST + onlay results in ACN in 6.1% (p <0.05) patients. Reduced contact of the mesh with the subcutaneous tissue in ACST + IPOM contributes to a significantly lower incidence of seroma [7.3% vs 25.6% (p <0.05)], surgical site infection (SSI) [2.4% vs 4.9% (p> 0.05)], postoperative wound infiltrate [2 (2.4%) vs. 11 (13.4%) (p <0.05)], chronic postsurgical pain [1 (1.6%) vs. 5 (8.1%) (p> 0.05)] and recurrent IH [1 (1.6%) vs. 4 (6.5%) (p> 0.05)] as compared with ACST + onlay technique.

Bolid elektryczny MuSHELLka, startujący w światowych zawodach Shell Eco-marathon w 2013 roku, wyposażono w aktywne systemy bezpieczeństwa: BLIS (system informujący kierowcę o pojawieniu się obiektu w mar-twym polu), ACC (system skanujący przestrzeń przed bolidem), ACS (system działający w przypadku kolizji). Bazują one na istniejących systemach, które są wykorzystywane obecnie w samochodach. Dostosowanie tych systemów na potrzeby bolidu elektrycznego MuSHELLka było bardzo skomplikowane, jednak za pomocą specjalnego oprogramowania PreScan firmy TASS zaprojektowano jei przebadano tak, aby zapewniały kierowcy i jego konkurentom większe bezpieczeństwo. Słowa kluczowe: systemy bezpieczeństwa, zaawansowany system wspomagania kierowcy, systemy automatyki jazdy, PreScan, Bolid MuSHELLka, Shell Eco-marathon, system informacji „martwego pola”, system informacji o wyprzedzaniu, system bezpieczeństwa w przypadku kolizji.

Electric vehicle MuSHELLka during development for 2013 Shell Eco-marathon, has been equipped with active safety systems. Blind Spot Information System, Adaptive Cruise Control and Automatic Crash System. All those systems will ensure driver and his opponents more safety. Projects of submitted systems based on real layouts which are nowadays in cars. Adaptation of those systems for our vehicle and race needs were complicated. With aid of special software PreScan from TASS, which is a computer simulator for advanced driver assistance systems, there were possibilities to design and test safety systems in the specified environment. It is an urban racetrack in Rotterdam, Holland. Also there were capabilities to specify sensors and their properties. Entirely with MATLAB/Simulink software have given opportunity to build and verify selected safety systems.
