“…The morphological characteristics of conidia after exposure to plasma were assessed using a CX51 light microscope (Olympus, Optical Co. Ltd., Tokyo, Japan) and compared with control conidia that were not exposed to plasma. (Limsopatham et al, 2017). These OES findings showed that that the working gas excited at high intensity and ignited other ionized species as planned.…”

This study was aimed to determine the effects of a plasma jet of mixed argon and oxygen (Ar‐O2) on Aspergillus flavus growth in potato dextrose broth (PDA). Settings for power, discharge duration, and gas flow rate of the plasma jet system (PJS) were optimized over ranges of 10–20 W, 1–10 min, and 3–9 L/min, respectively. The optimal conditions required to inhibit 100% of A. flavus growth at 30°C for 48 hr were 20 W, 10 min, and 9 L/min, respectively. The PJS inhibited 100% of the A. flavus growth in 20 replicates of infected peeled peanuts. Aspergillus flavus cell walls were destroyed via lipid and cell membrane oxidization, resulting in lost osmotic capability and damaged DNA and enzymes. However, the PJS is limited by a short exposure distance. More power, longer exposure, and increased gas flow might be needed to increase the distance while maintaining 100% microbial growth inhibition. Application to real foods and agricultural products, and upscaling the PJS for industrial use will be assessed in further studies. Practical applications Our proposed plasma system could be applied to postharvested agricultural products such as dried peanuts and chili. However, the technology will require validation before it can be applied in an industrial scale.

“…However, two peaks (336.2 and 397.3 nm) were associated with the optical transitions of excited N 2 at low intensity. A low‐intensity OH • peak was also evident at 309.8 nm (Limsopatham et al., 2017). These OES findings showed that that the working gas excited at high intensity and ignited other ionized species as planned.…”

“…It was shown that NTP allows keratinocytes to escape from G1 cell cycle arrest, increases the cell proportion in S and G2 phases, causes translocation of beta-catenin to nucleus and induces the transcription of target genes without damaging DNA (125). Moreover, another study has tested the effects of cold argon plasma on eggs of blow fly (126). Larvae of this fly produce myiasis which is a parasitic infection where larvae grow inside the host while feeding on its tissues.…”

Infrastructure in animal husbandry refers to fundamental facilities and services necessary for better living conditions of animals and its economy to function through better productivity. Mainly, infrastructure can be divided into two categories: hard infrastructure and soft infrastructure. Physical infrastructure, such as buildings, roads, and water supplying systems, belongs to hard infrastructure. Soft infrastructure includes services which are required to maintain economic, health, cultural and social standards of animal husbandry. Therefore, the proper management of infrastructure in animal husbandry is necessary for animal welfare and its economy. Among various technologies to improve the quality of infrastructure, non-thermal plasma (NTP) technology is an effectively applicable technology in different stages of animal husbandry. NTP is mainly helpful in maintaining better health conditions of animals in several ways via decontamination from microorganisms present in air, water, food, instruments and surfaces of animal farming systems. Furthermore, NTP is used in the treatment of waste water, vaccine production, wound healing in animals, odorfree ventilation, and packaging of animal food or animal products. This review summarizes the recent studies of NTP which can be related to the infrastructure in animal husbandry.

Розглянуто електромагнiтний метод для знищення личинок мух-шкiдникiв сiльського господарства. З цiєю метою вирiшено задачу про розподiл електромагнiтних полiв у їхньому органiзмi. Рiшення проводиться на основi рiвнянь Максвелла в iнтегральнiй формi, якi автоматично враховують граничнi умови на поверхнi розсiювачiв. Оскiльки пропонується електромагнiтне випромiнювання, довжина хвилi якого значно бiльша лiнiйних розмiрiв комах, отриманi iнтегральнi рiвняння визначенi в наближеннi квазiстатики. Це дозволило перетворити iнтегральнi рiвняння в систему лiнiйних неоднорiдних рiвнянь алгебри, рiшенням яких стали компоненти електричного поля всерединi личинок мух. Дослiдження проведенi для одношарових i двошарових комах елiпсоїдної форми. Отриманi поля дають можливiсть визначити величини потенцiалiв, що виникають на покриттi личинки, а також з'ясувати при яких значеннях вiдбувається пробiй цього покриття, тобто загибель личинки мухи. Для отримання залежностi, що зв'язує кiлькiсть iмаго з личинок мух з параметрами електромагнiтного випромiнювання при наявностi адитивної перешкоди випадкового характеру, може бути застосовано повнофакторне планування другого порядку. Впливом електромагнiтних полiв пiддавалися личинки мухи кiнця другого вiку. Опромiнення личинок мухи електромагнiтним випромiнюванням здiйснювалося в дiапазонi частот 10,2-9,8 ГГц, щiльнiстю потоку потужностi 0,62-0,38 мВт/см 2 i експозицiєю 2-12 с. Розвиток личинок спостерiгався до формування та виходу дорослої комахи. На основi багатофакторного експерименту знайдено оптимальнi значення частот опромiнення, щiльностi потоку потужностi i експозицiї. Для пригнiчення комах в тваринницьких примiщеннях, починаючи зi стадiї личинки i до виходу iмаго, необхiдне електромагнiтне випромiнювання з параметрами: частота 10,2 ГГц; щiльнiсть потоку потужностi 0,37 мВт/см 2 ; вiдносна нестабiльнiсть частоти генератора 10-8 ; експозицiя 6 с. Вихiд iмаго з лялечок личинок мух в тваринницькому примiщеннi, опромiнених електромагнiтним випромiнюванням, склав менше 5 %. Проведений експеримент з поросятами показав, що при хiмiчному методi обробки примiщення прирiст в живiй вазi склав 7,2 %, а при електромагнiтному способi-9,2 %. Менший прирiст в живiй вазi при хiмiчнiй обробцi пов'язаний з тим, що хiмiчний розчин негативно впливає не тiльки на мух i їх личинки, а й на тварин. Проведенi дослiдження можуть бути використанi для створення промислових установок по знищенню мух в тваринницьких примiщеннях Ключовi слова: знищення личинок мух, iнтегральнi рiвняння Максвелла, параметри електромагнiтного поля UDC 632.935.4
