High cGMP levels keep cGMP-gated ion channels in the open state and allow them to pass an inward Na+ current (Figure 2). As of 2011, the price of PV modules has fallen by 60% since the summer of 2008, according to Bloomberg New Energy Finance estimates, putting solar power for the first time on a competitive footing with the retail price of electricity in a number of sunny countries; an alternative and consistent price decline figure of 75% from 2007 to 2012 has also been published, though it is unclear whether these figures are specific to the United States or generally global. c. the direct transfer of DNA from one bacterium to another. Copper indium gallium selenide solar cells, Solar-Powered Aircraft Developments Solar One, List of countries by photovoltaics production, https://en.wikipedia.org/w/index.php?title=Photovoltaics&oldid=998329911, Wikipedia articles needing page number citations from February 2017, Articles with self-published sources from February 2017, Short description is different from Wikidata, Articles with unsourced statements from November 2020, Articles with unsourced statements from March 2016, Wikipedia articles with SUDOC identifiers, Creative Commons Attribution-ShareAlike License. Photovoltaics definition, a field of semiconductor technology involving the direct conversion of electromagnetic radiation as sunlight, into electricity. However, electricity networks traditionally are not designed to deal with two-way energy transfer, which may introduce technical issues. The primary driving force for the self-assembly of lipid molecules is their amphiphilic character: they possess a hydrophilic headgroup and a hydrophobic tail , .When in an aqueous environment, the lipids will spontaneously self-assemble to minimize the exposure of the hydrophobic lipid tails to the water. Solar cells convert some of the light energy absorbed into electrical energy. , For best performance, terrestrial PV systems aim to maximize the time they face the sun. Because organic photovoltaics require very high purity and are relatively reactive they must be encapsulated which vastly increases cost of manufacturing and meaning that they are not feasible for large scale up. , Solar power is pollution-free during use, which enables it to cut down on pollution when it is substituted for other energy sources. Cell receptors can be activated by binding certain extracellular ligands. In addition, worldwide electricity prices came under strong pressure from renewable energy sources, that are, in part, enthusiastically embraced by consumers. Such policies are implemented to promote national or territorial energy independence, high tech job creation and reduction of carbon dioxide emissions which cause climate change. Researchers at these labs have quickly achieved cell efficiencies of 20-25%, matching or exceeding those of silicon solar cells. Life Cycle Greenhouse Gas Emissions from Solar Photovoltaics, National Renewable Energy Laboratory, U.S. Department of Energy, 2012, 1–2. Chapter 55 Neurology: Sensory Nervous System AUDITORY TRANSDUCTION & PATHWAYS osms.it/auditory-transduction-and-pathways Process by which ear converts sound waves into electrical pulses OUTER EAR Ampliﬁes sound, directs sound waves Pinna → external auditory canal → eardrum vibrates MIDDLE EAR Transmits airborne sound waves to inner ear Malleus (attached to eardrum) → …  by Contrary to established thin films such as CIGS and CdTe, CZTS, Zn3P2, and SWCNT PVs are made from earth abundant, nontoxic materials and have the potential to produce more electricity annually than the current worldwide consumption. Transduction happens through either the lytic cycle or the lysogenic cycle. Although some consolidation is likely in 2012, due to support cuts in the large markets of Germany and Italy, strong growth seems likely to continue for the rest of the decade. Crystalline silicon solar cell prices have fallen from $76.67/Watt in 1977 to an estimated $0.74/Watt in 2013. Transduction happens when a virus uses a bacterium cell to replicate itself by hijacking it.  A 2015 review of EPBT from first and second generation PV suggested that there was greater variation in embedded energy than in efficiency of the cells implying that it was mainly the embedded energy that needs to reduce to have a greater reduction in EPBT. Recent developments in Organic photovoltaic cells (OPVs) have made significant advancements in power conversion efficiency from 3% to over 15% since their introduction in the 1980s. Google Classroom Facebook Twitter. Nowadays, most PV systems are grid-connected, while stand-alone systems only account for a small portion of the market. With progress in optical computing and information processing, a new class of sensors, which involve the transduction of energy into an optical form, is likely. In 2019, worldwide installed PV capacity increased to more than 635 gigawatts (GW) covering approximately two percent of global electricity demand. This page was last edited on 6 November 2006, at 13:42. The activated phosphodiesterase hydrolyzes cGMP into GMP, reducing its concentration in the outer segment and leading to the closure of sodium channels in the outer segment membrane. In a biological photovoltaic system, electrons generated by photolysis of water are transferred …  This is seen as evidence supporting Swanson's law, an observation similar to the famous Moore's Law that states that solar cell prices fall 20% for every doubling of industry capacity.. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. Some single junction III-V cells have band gaps in the range of 1.8 to 1.9 eV, which have been shown to maintain good performances under indoor lighting, with an efficiency of over 20%. Lower solar module costs also stimulate demand from consumer markets where the cost of solar compares very favorably to retail electric rates. These binding events trigger a signaling cascade that allows the cell to respond appropriately to the stimulus. , Generous Feed-in tariff (FIT) and supporting policies such as tax exemptions are found to be the key proximate drivers of Vietnam's solar PV boom. The large range of reported values highlight the uncertainties associated with these studies. Proc Natl Acad Sci U S A. PV modules are mainly made of PV cells, which has no fundamental difference from the material used for making computer chips. The city of Berkeley developed an innovative financing method to remove this limitation, by adding a tax assessment that is transferred with the home to pay for the solar panels. Australian Ageing Agenda. Utility-scale solar power can now be delivered in California at prices well below $100/MWh ($0.10/kWh) less than most other peak generators, even those running on low-cost natural gas. There has been various organic photovoltaics that have demonstrated efficiencies of over 16% from indoor lighting, despite having low efficiencies in energy harvesting under sunlight.  As time progresses, renewable energy technologies generally get cheaper, while fossil fuels generally get more expensive: The less solar power costs, the more favorably it compares to conventional power, and the more attractive it becomes to utilities and energy users around the globe. Solar trackers achieve this by moving PV modules to follow the sun.  The cradle to gate of CO2-eq/kWh ranges from 28.5 to 69 grams. After being deposited onto the substrate the semiconducting layers are separated and connected by electrical circuit by laser scribing. Transduction involves the use of a virus, a bacteriophage, to act as a conduit for shuttling bacteria genes from one cell to another, thus negating the necessity for cell-to-cell contact.  CIGS is approximately 1/100th the thickness of conventional silicon solar cell technologies. One of the annoying things that happens when you track developing science is that you keep seeing interesting results on a topic, but none of them quite reaches the significance to justify a news story. Barclays expects more competition by a growing self-consumption due to a combination of decentralized PV-systems and residential electricity storage.  OPVs fall into the thin-film category of manufacturing, and typically operate around the 12% efficiency range which is lower than the 12–21% typically seen by silicon based PVs. The precursor for 11-cis-retinal is all-trans-retinol (vitamin A). Materials necessary for assembly are readily available, and are less costly per watt of solar cell. This is due to: "the rapidity of cost and price changes, the complexity of the PV supply chain, which involves a large number of manufacturing processes, the balance of system (BOS) and installation costs associated with complete PV systems, the choice of different distribution channels, and differences between regional markets within which PV is being deployed".  A photo detector has a p–n junction that converts light photons into current. The method involves durably connecting conductive, tinned copper fillets (3) with a cell surface by a reflow soldering process for making mechanical and electrical connection of crystalline solar cells (1) to cell strings (2) such that the cells and the copper fillets are carried on a conveyor by a closed system.  The cradle to gate of CO2-eq/kWh ranges from 37.3 to 72.2 grams. When there is more local generation than consumption, electricity is exported to the grid, allowing for net metering. The EPBT is defined as " the time needed to compensate for the total renewable- and non-renewable- primary energy required during the life cycle of a PV system". Next, the wafers are placed into a phosphorus vapor deposition furnace which lays a very thin layer of phosphorus, a group V element, which creates an n-type semiconducting surface. , The electrical efficiency of a PV cell is a physical property which represents how much electrical power a cell can produce for a given Solar irradiance. This process mainly includes a sensing element to sense the i… (3) Inactivation of phosphodiesterase (PDE) is coupled to the inactivation of transducin. Fundamental Concepts in Organic Reaction Mechanism. Rods are very sensitive cells specialized for night vision. To increase electrical output of a PV sheet metal roof. 1.2. Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. 1993; Rao, VR et al. Phototransduction thus enables the photoreceptor to encode a light stimulus as a chemical output. because of this economies of scale are important for manufacturers as costs In one such study, conventional energy mix in Greece was compared to multi-si PV and found a 95% overall reduction in impacts including carcinogens, eco-toxicity, acidification, eutrophication, and eleven others.. Second is European Union with 132 GW. Key Difference – Transfection vs Transduction In biotechnology and genetic engineering, foreign genes are introduced into genomes of the organisms with the objective of improving characteristics of the organisms. CIS and CIGS are often used interchangeably within the CIS/CIGS community. , Crystalline silicon photovoltaics are only one type of PV, and while they represent the majority of solar cells produced currently there are many new and promising technologies that have the potential to be scaled up to meet future energy needs. Cells, normally made from silicon, are arranged on a module, and multiple modules are strung together to create the desired system size. 88(20):9370-4 (1991), Dryja, TP et al.  Concentrated photovoltaics (CPV) may reduce cost by concentrating up to 1,000 suns (through magnifying lens) onto a smaller sized photovoltaic cell. PV has become the cheapest source of electrical power in regions with a high solar potential, with price bids as low as 0.01567 US$/kWh in 2020. Generalised transduction is mediated by lytic phages where any DNA segment can be transferred by the virus and may not integrate the segment to the bacterial chromosome. Transfection and transduction are common tools used in Biotechnology to introduce foreign genes into host cells.  EPBT ranges from 1.5 to 2.6 years. Transduction. Osteoclast Signal Transduction During Bone Metastasis Formation Front Cell Dev Biol. Renewable Energy Policy Network for the 21st century (REN21), CS1 maint: multiple names: authors list (. Doing so allows visible light to reach the solar cells, but reflects infrared rays (which carry heat).. There are various electrical and electronic components are used to build the circuits and projects for engineering students. First, polysilicon is processed from mined quartz until it is very pure (semi-conductor grade). Photovoltaic (PV) systems consist of a number of components. Protein phosphorylations change enzyme activities and … Therefore, a single activated rhodopsin can cause the hydrolysis of more than 10^5 molecules of cGMP per second. Another recent development involves the material content of solar cells. Silicon Solar Cells by Martin A. , In many locations, PV has reached grid parity, which is usually defined as PV production costs at or below retail electricity prices (though often still above the power station prices for coal or gas-fired generation without their distribution and other costs). Signal transduction is the process by which a cell recognizes changes in its environment and transforms that signal into modifications in cellular activity and gene expression. , Techniques to produce multi-crystalline silicon (multi-si) photovoltaic cells are simpler and cheaper than mono-si, however tend to make less efficient cells, an average of 13.2%. Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry.

He also asserts, that the electrical grid has been greatly expanded worldwide, and is ready to receive and distribute electricity from renewable sources. Inductive effects involves : A. displacement of σ electrons resulting in … Phototransduction involves three main biochemical events: Light entering the eye activates the opsin molecules in the photoreceptors. Answer Save. chemoreceptors. , While there are many types of PV systems known to be effective, crystalline silicon PV accounted for around 90% of the worldwide production of PV in 2013. Defects in RGS9 or its anchor protein R9AP in patients with slow photoreceptor deactivation. Similarly, reported EPBT of the published paper range from 0.2 to 15 years. In Transduction, DNA is transferred from one cell to another through the agency of viruses. For behind-the-meter rooftop photovoltaic systems, the energy flow becomes two-way. Signal transduction triggered by each cascade involves the sequential phosphorylation and activation of the components in the subsequent tiers. In the dark, the activity of this enzyme is relatively weak. Jennifer L. Braid, Roger H. French, in Durability and Reliability of Polymers and Other Materials in Photovoltaic Modules, 2019. Upon photon absorption, 11-cis-retinal undergoes an isomerization to the all-trans form, causing a conformational change in the rhodopsin. system, the manufacturer must simply add more photovoltaic components and The components are active and passive components, sensors, transducers, transmitters, receivers, modules (WiFi, Bluetooth, GSM, RFID, GPS), and so on. This disorder, which often leads to blindness, can result from mutations in a variety of genes expressed in photoreceptors (Hamel, C. 2006). The membrane potential of a photoreceptor hyperpolarizes in response to light, causing a reduction in the amount of neurotransmitter released by the photoreceptor onto downstream neurons.  The total power output of the world's PV capacity in a calendar year is now beyond 500 TWh of electricity. (Neuroscience, Purves et al., 2001). Due to the instability of perovskite cells lead may eventually be exposed to fresh water during the use phase. The light response is terminated by several mechanisms. Cells require protection from the environment and are usually packaged tightly in solar modules.  Toxicity is an issue within the buffer layer of CIGS modules because it contains cadmium and gallium. The efficiency of a solar cell declines by about 0.5% for every 1 degree Celsius increase in temperature. 1994). In bright light conditions the response of the rods is saturated and cones, faster but less sensitive photoreceptors, mediate day vision. Help. Generalized Transduction . These events include phosphorylations by tyrosine kinases and/or serine/threonine kinases. A key second messenger molecule responsible for maintaining a depolarized rest state in photoreceptors is the nucleotide cyclic guanosine 3’-5’ monophospate (cGMP). , Another newer technology, thin-film PV, are manufactured by depositing semiconducting layers on substrate in vacuum. This stimulus-induced hyperpolarization is a distinctive characteristic of the photoreceptor response, as many other neuronal types depolarize when stimulated.  This abundance leads to the suggestion that it will not be long before solar energy will become the world's primary energy source. The method involves moving mounting rails (4) e.g. Perovskite solar cells have been tested to display efficiencies over 25% in low light levels. The process of producing PV cells is energy-intensive and involves highly poisonous and environmentally toxic chemicals. Second State is USA with 76 GW. gp130-mediated Signal Transduction in Embryonic Stem Cells Involves Activation of Jak and Ras/Mitogen-activated Protein Kinase Pathways* Matthias Ernst, Andrew Oates and Ashley R. Dunn ‡ From the Ludwig Institute for Cancer Research, Melbourne Tumour Biology Branch, P.O. electromagnetic receptor _____ are triggered when stimuli become too extreme for thermoreceptors. PV systems range from small, roof-top mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts. Organic and polymer photovoltaic (OPV) are a relatively new area of research. This disorder also manifests as an inability to sense the movement of objects in a bright environment. Transduction: generalized and specialized transduction.  The cell structure includes glass substrate (around 2 mm), transparent conductor layer, CdS buffer layer (50–150 nm), CdTe absorber and a metal contact layer. The tradition OPV cell structure layers consist of a semi-transparent electrode, electron blocking layer, tunnel junction, holes blocking layer, electrode, with the sun hitting the transparent electrode. OPV replaces silver with carbon as an electrode material lowering manufacturing cost and making them more environmentally friendly. 10th is France with 10 GW.  While CZTS and Zn3P2 offer good promise for these reasons, the specific environmental implications of their commercial production are not yet known. Due to economies of scale solar panels get less costly as people use and buy more—as manufacturers increase production to meet demand, the cost and price is expected to drop in the years to come. Human photoreceptor topography. Each step of that ladder is the middle axis of a rectangular solar panel. Additionally, using PV solar power to charge DC batteries, as used in Plug-in Hybrid Electric Vehicles and Electric Vehicles, leads to greater efficiencies.

Solar cell energy conversion efficiencies for commercially available photovoltaics are around 14–22%. Self-cooling solar cells are one solution to this problem. a price for the highest 30min energy consumption in a month). The mount may be fixed or use a solar tracker to follow the sun across the sky. GTP-bound active transducin will increase the activity of cGMP phosphodiesterase. Organic Chemistry - Some Basic Principles and Techniques. Thus the definition of a "sensor" will continue to evolve. Transduction is a method of gene transfer in bacteria from donor to recipient using bacteriophage. Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction concentrated photovoltaics. A photovoltaic system, or solar PV system is a power system designed to supply usable solar power by means of photovoltaics. When this bacteriophage infects new bacterial cell, it transfer that DNA in to recipient cell. d. the transfer of bacterial …  More than 100 countries now use solar PV. different comfort/convenience needs, different electricity tariffs, or different usage patterns. In bright light conditions the response of the rods is saturated and cones, faster but less sensitive photoreceptors, mediate day vision. Transduction. The US-based specialty gallium arsenide (GaAs) PV manufacturer Alta Devices produces commercial cells with 26% efficiency claiming to have "the world's most efficient solar" single-junction cell dedicated to flexible and lightweight applications. Dye-sensitized PVs are similar in efficiency to OPVs but are significantly easier to manufacture. The values of human labor and water consumption, for example, are not precisely assessed due to the lack of systematic and accurate analyses in the scientific literature. Photovoltaic power generation employs solar modules composed of a number of solar cells containing a semiconductor material. Figure 1: An intracellular recording from a single cone stimulated with different amounts of light. High generation during the middle of the day reduces the net generation demand, but higher peak net demand as the sun goes down can require rapid ramping of utility generating stations, producing a load profile called the duck curve. During transfection, DNA is deliberately introduced into host cells while … However, such concentrated solar power requires sophisticated heat sink designs, otherwise the photovoltaic cell overheats, which reduces its efficiency and life. However, even with the same short lifetime, the 28% cell had lower environmental impacts than mono-Si. These modules perform maximum power point tracking (MPPT) for each module individually, measure performance data for monitoring, and provide additional safety features. And so you can imagine, it's going to bind to this membrane receptor, and so EGFR literally stands for epidermal growth factor receptor, EGF receptor. "tRNA possesses an anticodon complementary to an mRNA codon." Government has sometimes also offered incentives in order to encourage the PV industry to achieve the economies of scale needed to compete where the cost of PV-generated electricity is above the cost from the existing grid.  The actual power output at a particular place may be less than or greater than this rated value, depending on geographical location, time of day, weather conditions, and other factors. Third is Japan with 63 GW.  According to the forecast, PV could become the technology with the largest installed capacity by the mid 2020s. Opsin is bound to a light-absorbing chromophore, 11-cis-retinal (an aldehyde of vitamin A). The photovoltaic effect is commercially utilized for electricity generation and as photosensors. Persistent activation of the phototransduction cascade limits the fidelity of the light response by rod photoreceptors. Sensory transduction can involve which of the following? Method for constructing house, involves installing geothermal heat pump with collector under foundation base plate, and arranging photovoltaic system for generating current . At the highest light levels, the response amplitude saturates. Apoptose oder Wachstumsstillstand: Modulation der zellulären Antwort auf p53 durch proliferative Signale 15. Also, sensors based on microelectromechanical systems may enable fluidic elements to operate as controls and actuation devices in the future. Wafers of this semiconductor material are cut from the bulk material with wire saws, and then go through surface etching before being cleaned. Absorbance spectra of rod and cone photoreceptors (Purves, p.239, 2001). Since large-scale PV operation requires back-up in the form of spinning reserves, its marginal cost of generation in the middle of the day is typically lowest, but not zero, when PV is generating electricity. It consists of an arrangement of several components, including solar panels to absorb and directly convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling and other electrical accessories. Multiple Choice . , Other emerging PV technologies include organic, dye-sensitized, quantum-dot, and Perovskite photovoltaics. There are several groups of materials that are being developed. PV has been a well-known method of generating clean, emission-free electricity. This process consists of sensing with specificity the input energy from the measurand by means of a "sensing element" and then transforming it into another form by a " transduction element.

Dnes jsou cílem k trestání Maďarsko a Polsko, zítra může dojít na nás
„Pouze nezávislý soudní orgán může stanovit, co je vláda práva, nikoliv politická většina,“ napsal slovinský premiér Janša v úterním dopise předsedovi Evropské rady Charlesi Michelovi. Podpořil tak Polsko a Maďarsko a objevilo se tak třetí veto. Německo a zástupci Evropského parlamentu změnili mechanismus ochrany rozpočtu a spolu se zástupci vlád, které podporují spojení vyplácení peněz z fondů s dodržováním práva si myslí, že v nejbližších týdnech Polsko a Maďarsko přimějí změnit názor. Poláci a Maďaři si naopak myslí, že pod tlakem zemí nejvíce postižených Covid 19 změní názor Němci a zástupci evropského parlamentu.
Mechanismus veta je v Unii běžný. Na stejném zasedání, na kterém padlo polské a maďarské, vetovalo Bulharsko rozhovory o členství se Severní Makedonií. Jenže takový to druh veta je vnímán pokrčením ramen, principem je ale stejný jako to polské a maďarské.
Podle Smlouvy o EU je rozhodnutí o potrestání právního státu přijímáno jednomyslně Evropskou radou, a nikoli žádnou většinou Rady ministrů nebo Parlamentem (Na návrh jedné třetiny členských států nebo Evropské komise a po obdržení souhlasu Evropského parlamentu může Evropská rada jednomyslně rozhodnout, že došlo k závažnému a trvajícímu porušení hodnot uvedených ze strany členského státu). Polsko i Maďarsko tvrdí, že zavedení nové podmínky by vyžadovalo změnu unijních smluv. Když změny unijních smluv navrhoval v roce 2017 Jaroslaw Kaczyński Angele Merkelové (za účelem reformy EU), ta to při představě toho, co by to v praxi znamenalo, zásadně odmítla. Od té doby se s Jaroslawem Kaczyńskim oficiálně nesetkala. Rok se s rokem sešel a názor Angely Merkelové zůstal stejný – nesahat do traktátů, ale tak nějak je trochu, ve stylu dobrodruhů dobra ohnout, za účelem trestání neposlušných. Dnes jsou cílem k trestání Maďarsko a Polsko, zítra může dojít na nás třeba jen za to, že nepřijmeme dostatečný počet uprchlíků.
Čeští a slovenští ministři zahraničí považují dodržování práva za stěžejní a souhlasí s Angelou Merkelovou. Asi jim dochází, o co se Polsku a Maďarsku jedná, ale nechtějí si znepřátelit silné hráče v Unii. Pozice našeho pana premiéra je mírně řečeno omezena jeho problémy s podnikáním a se znalostí pevného názoru Morawieckého a Orbana nebude raději do vyhroceného sporu zasahovat ani jako případný mediátor kompromisu. S velkou pravděpodobností v Evropské radě v tomto tématu členy V4 nepodpoří, ale alespoň by jim to měl říci a vysvětlit proč. Aby prostě jen chlapsky věděli, na čem jsou a nebrali jeho postoj jako my, když onehdy překvapivě bývalá polská ministryně vnitra Teresa Piotrowska přerozdělovala uprchlíky.
Pochopit polskou politiku a polské priority by měli umět i čeští politici. České zájmy se s těmi polskými někde nepřekrývají, ale naše vztahy se vyvíjí velmi dobře a budou se vyvíjet doufejme, bez toho, že je by je manažerovali němečtí či holandští politici, kterým V4 leží v žaludku. Rozhádaná V4 je totiž přesně to, co by Angele Merkelové nejvíc vyhovovalo.
Morawiecki: Hřbitovy budou na Dušičky uzavřeny
V sobotu, neděli a v pondělí budou v Polsku uzavřeny hřbitovy – rozhodla polská vláda. Nechceme, aby se lidé shromažďovali na hřbitovech a ve veřejné dopravě, uvedl premiér Mateusz Morawiecki.
„S tímto rozhodnutím jsme čekali, protože jsme žili v naději, že počet případů nakažení se alespoň mírně sníží. Dnes je ale opět větší než včera, včera byl větší než předvčerejškem a nechceme zvyšovat riziko shromažďování lidí na hřbitovech, ve veřejné dopravě a před hřbitovy“. vysvětlil Morawiecki.
Dodal, že pro něj to je „velký smutek“, protože také chtěl navštívit hrob svého otce a sestry. Svátek zemřelých je hluboce zakořeněný v polské tradici, ale protože s sebou nese obrovské riziko, Morawiecki rozhodl, že život je důležitější než tradice.
Poslankyně opozice atakovaly předsedu PiS
Ochranná služba v Sejmu musela oddělit lavici, ve které sedí Jaroslaw Kaczyński od protestujících poslankyň.
„Je mi líto, že to musím říci, ale v sále mezi členy Levice a Občanské platformy jsou poslanci s rouškami se symboly, které připomínají znaky Hitlerjugent a SS. Chápu však, že totální opozice odkazuje na totalitní vzorce.“ řekl na začátku zasedání Sejmu místopředseda Sejmu Ryszard Terlecki.
Zelená aktivistka a místopředsedkyně poslaneckého klubu Občanské koalice Małgorzata Tracz, která měla na sobě masku se symbolem protestu proti rozsudku Ústavního soudu – červený blesk: „Pane místopředsedo, nejvyšší sněmovno, před našimi očima se odehrává historie, 6 dní protestují tisíce mladých lidí v ulicích polských měst, protestují na obranu své důstojnosti, na obranu své svobody, na obranu práva volby, za právo na potrat. Toto je válka a tuto válku prohrajete. A kdo je za tuto válku zodpovědný? Pane ministře Kaczyński, to je vaše odpovědnost.“
