Econ160 Essay Example | Topics and Well Written Essays - 1250 words - 1

Econ160 - Essay Example My parents belongs to several generation of Guanxi where I am expected to inherit his position. If I will be living in China, I better be sure with the place that I will live. It is because the Chinese government prohibits the reselling of houses as their policy response to avoid speculation in the housing industry. I will be stuck in the house that I will choose for a very long period of time so I better take my time before buying a house. Unlike in the US where the housing market is determined by market forces as enunciated by Friedman in the book Capitalism and Freedom where price and availability is determined by the law of supply and demand where I can resell my house anytime I want it subject to the same law (supply and demand), Chinese government will just not allow the resell and even pegged the price. China may now allows private ownership of houses only with restrictions. With my present economic stature, I believe I would be able to afford a house and not in a crampy apartment or shoebox as what Hedrick Smith had described in his book The Russians. Only that my house will not form part of my estate where I can resell for profit or I will go to jail. If I will be in China, choosing my occupation will be partly determined with how the â€Å"opportunities† present to me. Unlike in the US where choosing an occupation is determined by personal preference and applying on it base on merit, it will be different in China. The cliche its whom you know more than what you know applies. If my father belongs to a Guanxi or the network of power elites, he may recommend me to some of his associates in the network as expounded by McGregor in his book The Party and will accept whatever occupation that will be given to me. From there, my future will be secured because I will be under the patronage and care of my father’s Guanxi and I will later develop my own network. I will first learn the rope of the business until I

Asda and Tesco - Restructuring to reflect multichannel markets - Assignment Example Therefore, the study has utilized different leadership theories to explain the required traits and skills for the new managerial positions. The report is based on the study of the current restructuring plans of Asda and Tesco, the two retail giants of the UK. This report has also emphasised on different theories of leadership practices in any business environment, to understand the relevance of these theories in the restructuring plans of Asda and Tesco. Tesco Plc. is one of the leading supermarket chains in the UK. Tesco has its stores in 12 countries worldwide and it generally deals with food, books, clothes, electronic gadgets and furniture. The company is successfully restructuring its multichannel market operations over a period of time. In this process, they are redeploying near about 100 staffs to new job roles. They are also creating several vacancies across the organisation. Their initiative called â€Å"Building tomorrow’s Tesco† is focused on achieving the global multichannel leadership (Channel management, 2014). Asda stores Ltd. is a renowned name in the retail industry of the UK. The organisa tion deals in grocery items, general merchandise, clothes and toys. Following the trend of Tesco, Asda is also focusing on a massive restructuring of its multichannel business operations. They are creating near about 5670 new roles for various departments of its multichannel operations (Harrison, 2014). These restructuring plans are massively changing leadership roles and responsibilities of several employees in these organisations. The importance of different leadership theories on the success of the restructuring plans of these organisations have been described in this report. Leadership in an organisation describes the role where leaders utilize the available resource and capabilities of a team to attain a common goal. The

National Security Essay Example | Topics and Well Written Essays - 2500 words

National Security - Essay Example According to the discussion findings the term terrorism is politically and psychologically charged, and this to a great extent compounds the complicatedness of providing an accurate definition. In 1988, one study by the US Army established that over hundred definitions of the utterance terrorism have been used. A person who applies terrorism is a terrorist. The idea of terrorism is itself contentious for the reason that it is frequently used by states to delegitimise political adversary, and hence legitimize the state's own employ of terror adjacent to those opponents. As the paper declares terrorism has been second-hand by a wide array of political organizations in getting more to their objectives; together right and left-wing political parties, patriotic, and holy groups, innovative and ruling governments. The occurrence of non-state performers in widespread-armed clash has created hullabaloo regarding the submission of the laws of war. Despite the fact that acts of terror campaign are criminal acts as for each the United Nations Security Council Resolution and domestic jurisprudence of approximately all countries in the world, terrorism refers to an observable fact including the definite acts, the perpetrators of acts of bombing and their intentions. Terror is from a Latin word that means ‘to frighten’. The terror was a panic and condition of emergency in Rome in reaction to the approach of warriors of the tribe of Cimbri in 105BC. The Jacobins cited this approach when he imposed a Reign of Terror during the French Revolution. The w ord terrorist became a word of abuse after the Jacobins lost power. Even though the Reign of Terror was being imposed by a government, in modern times terrorism normally is referred to the killing of innocent people by a group in such a manner as to manufacture a media spectacle. In 1869Nechayev made the Russian terrorist group People's Retribution. A United Nations Security Council report stated in November 2004: 'Terrorism as any act intended to cause death or serious bodily harm to civilians or non-combatants with the purpose of intimidating a population or compelling a government or an international organization to do or abstain from doing any act'. History of Terrorism The word "terrorism" was at first used to explain the actions of the Jacobin Club throughout the "Reign of Terror" in the French revolt. Edmund Burke criticized the Jacobins for letting thousands of persons hell hounds called terrorists movable upon the people of France in 1795. Italian patriot Felice Orsini heaves three bombs in an attempt to assassinate French Emperor Napoleon III in January 1858. Eight eyewitnesses were killed and 142 injured. The event played a vital role as an encouragement for the expansion of the early Russian terrorist

Literature Review Rough Draft Research Paper Example | Topics and Well Written Essays - 750 words

Literature Review Rough Draft - Research Paper Example Cho et al. (2009) measured staffing with the help of two indicators; the first being the number of patients attended by a nurse counted at unit level, and the second being nurses’ perceptions of the adequacy of staffing. Cho et al. (2009) measured the quality of care and dissatisfaction with job using a burnout and a four-point scale gauged with the help of the Maslach Burnout Inventory, and determined the relationships between the three variables using the multilevel logistic regression models. Their research led them to the conclusion that nurse staffing is related to the care quality as well as job outcomes in the intensive care units of Korean hospitals. This conclusion was drawn on the basis of these findings; 20 per cent of the nurses perceived that the number of nurses needed to provide quality care was sufficient, whereas 33.33 per cent of the nurses were dissatisfied, 50 per cent were extremely burnt out with 25 per cent nurses contemplating to leave the hospital in t he following year. The optimal number of patients per nurse for high quality care as determined by the nurses was two or fewer. Kiekkas et al. (2008) explored variations in mortality of intensive care unit (ICU) patients based on the ratio between the total demands of patient care and staffing of nurses. Unlike Cho et al. (2009), whose design of research was cross-sectional along with a survey spanning August to October 2007, Kiekkas et al. (2008) conducted an observational and prospective study. Another major difference between the research of Cho et al. (2009) and Kiekkas et al. (2008) is that while the former included 1365 nurses in the survey who belonged to 65 units of intensive care in 22 different Korean hospitals to study the relationship between the staffing of nurses and the quality of nursing care related to nurses and job outcomes, the latter enrolled patients who were consecutively admitted in a Greek hospital’s medical

Effects of Microwave Doses on Seed Exposure

Effects of Microwave Doses on Seed Exposure Abstract A massive increase in electromagnetic pollution since the introduction of telecommunication instruments especially microwave from which the mobile communication. Current research study aim to assess the physiological effects of seed exposure to different doses of microwave. Microwave-induced electrolyte leakage, germination, chlorophyll and growth were monitored and evaluated following seed exposure to microwave from a magnetron of 2.45 GHz, maximum output power of 800 W and wavelength of 12 cm operated at 220 VAC. seeds of Hordeum vulgare were exposed to eight different exposure periods of microwave from 0 to 600 seconds, experiments were performed in vitro. Percentage of germinated seeds, relative germination coefficient, germination rate, germination index, fresh and dry weights, shoot: root ratio were assessed. Germination parameters were dose-dependents, the percentage of germinated seeds were increased after short exposure periods to microwave recording 100 % germination. Furth er the germination rate, relative germination coefficient were also increased after short exposure periods to microwave. Longer exposure periods reduced the percentage of germination, germination rates and various germination indices. Morphological and growth traits showed a similar trend and were significantly decreased after longer exposure periods to microwave. Chlorophyll contents were significantly decreased with increasing exposure periods of microwave. Microwave-induced electrolyte leakage (%) was significantly increased (r=0.92*, p Key words: Microwave, electromagnetic, barley, membrane ion leakage, cell death, germination, chlorophyll, SPAD, growth, Hordeum vulgare L. Introduction The Development of life was influenced by two ubiquitous forces; the gravity and electromagnetism, the two forces expected to have essential role in the functional activities of biological systems and organisms (Balmori, 2009). Previously, microwave radiofrequencies included a few radio and televisions transmitter located in remote area or high places. A massive increase in electromagnetic pollution since the introduction of telecommunication instruments in the 1990s (Galeev, 2000; Firstenberg, 2001; Ragha et al., 2011) (Ragha et al., 2011). These electromagnetic fields can have a deleterious and damaging effects depending on the exposure doses, power level, frequencies, pulsed or continuous wave and the dielectric properties of exposed tissue, the interaction of such electromagnetic fields on various life processes has been focused on different microwave frequency range forms an important part (Banik et al., 2003). Microwave are a part of electromagnetic radiations spectrum comprisi ng frequencies ranging from 300 MHz to 300 GHz, further, it act through absorption on molecular level manifesting as vibrational energy or heat and a biological effects (Chipley, 1980; Dardanonl et al., 1985, 1994; Pakhomov et al., 1998)(Chipley, 1980; Dardanoni et al., 1985; 1994; Pakhomov et al., 2001) including various genetic changes. Relevant research suggests that microwaves may have long-term health effects (Lin, 2004). Identification, evaluation and assessment of the bio-effects of microwaves have been complex and controversial, because of the absence of a clear mechanism of the impact and interaction of microwave radiofrequencies and biological systems, there has been a persistent view in biophysical and engineering sciences, that microwave fields are incapable of inducing bio-effects other than by heating (Banik et al., 2003). In recent times, non-thermal bio-effects of microwaves on tissue responses were being acknowledged (Dardalhon et al., 1979a,b; Adey, 1981; Banik et al., 2003). Various research data have offered convincing evidence of non-thermal microwave effects and have also indicated various consistencies in these effects: dependency of frequency within specific frequency windows of resonance-type; dependency on modulation and polarization; dependency on intensity within specific intensity windows, including super-low power density comparable with intensities from base stations/masts (Adey, 1981; Belyaev, 2005; Hyland, 2000; Lai, 2005, (De Salles, 1999; Scialabba and Tamburello, 2002)). Some studies have demonstrated different microwave effects depending on wavelength in the range of mm, cm or m (Kemerov et al., 1999; Nikolaevich et al., 2001). Duration of irradiation may be as important as power density (Abu-Elsaoud, 2015), the effect of electromagnetic radiations could be depending on the radiation exposure dose representing a long-term cumulative influence (Adey, 1997; Galeev, 2000; Lai, 2005; Abu-Elsaoud, 2015). Modulated and pulsed radiofrequencies seem to be more effective in producing effects (Belyaev, 2005; Lai, 2005). Low frequency modulations employ greater biological activity (Balmori, 2009). Microwave irradiation could affect plant growth, development and seed germination (Hamada, 2007; Aladjadjiyan, 2010; Salama et al., 2011; (Scialabba and Tamburello, 2002; Monteiro et al., 2008; Ragha et al., 2011; RadzeviÄ ius et al., 2013; (Abu-Elsaoud, 2015). Low intensity microwave were reported not to affect the plant growth and development but the increased irradiation doses of microwave has decreased and slowed seed germination (Oprica, 2008). The direct effects of microwave on germination of cereals were studied by Ponomarev et al. (1996) where, a wavelength ÃŽÂ »= 1 cm and irradiation exposure dose of up to 40 minutes were applied to barley, oats, and wheat seeds leading to improved germination rate with optimum effect after 20 minutes of microwave exposure (Ponomarev et al., 1996). A study of irradiating vegetable seeds with high power microwave radiations reported a stimulation influence of various germination and growth rate parameters by microwave (RadzeviÄà ‚ ius et al., 2013). The effect of microwave irradiation with a different power on various seed germination consequences of four different ornamental crop species has been studied by Aladjadjiyan (2002). The electroconductivity of leaf extract were monitored and increase in various germination consequences were observed (Aladjadjiyan, 2002). A comparative effect of microwave radiations on germination and growth of six different Egyptian genotypes were assessed using different exposure times, his data supported a dose dependent possible stimulation effect of microwave on growth and germination (Abu-Elsaoud, 2015). The response of barley seedlings to microwave radiations of 2.45 GHz after exposure to 0, 10, and 20 seconds of microwave radiations on four different genotypes (CreȆºescu et al., 2013). Changes in peroxidase and catalase enzyme activities in Brassica napus were found to be dependent on microwave exposure time, seed condition and plant age (Oprica, 2008). The freq uencies of the cell plasma membrane vibrations of bio-objects lie in the mm-wave range, that range is thought to be essential to any living organism. Microwave irradiations induce resonant phenomena within biological system and have a stimulatory effect on biological organisms (Aladjadjiyan, 2002; Yanenko et al., 2004). Most microwave irradiation studies focused on possible biological effects from phone masts and microwave radiofrequencies on animal and human health (Santini et al., 2003; Hutter et al., 2006; Balmori, 2009). The biochemical mechanism by which microwave radiations affect biological systems of living organisms is not fully comprehended and the mechanism could vary according to the amplitude, frequency and the irradiation duty cycle (Monteiro et al., 2008; Aladjadjiyan, 2010). The present study was conducted to study the effect of seed irradiation with different doses of microwave radiations on the membrane electrolyte leakage, germination and growth of Egyptian barley Hordeum vulgare L seedlings. Materials and methods Plant materials Seeds of selected Barely Hordeum vulgare L. genotype Giza-129 were acquired from Agricultural Research Station at Ismailia, Agricultural Research Centre (ARC), Giza, Egypt in the months of November-December, 2016. The cereal lot of seeds was cleaned removing unwanted matter and damaged seeds. Radiofrequency irradiation treatment Microwave radiofrequency irradiation were carried out using a magnetron with frequency of 2.45 GHz, wavelength of 12 cm, a maximum output power of 800 W, maximum intensity were estimated to be 51.5 kW.m3 by dividing the output power to the working volume m-3. Experimental details were presented in diagram (1). Seeds were first soaked in distilled water for 1 hour recommended by Aladjadjian and Svetleva (1997) to enhance the absorption of microwave energy. Seeds of selected barley genotype Hordeum vulgare cv. Giza-129 were divided into eight groups, each variant containing 30 seeds of (three replicas of ten seeds). The first group represent the untreated control and remaining seven variants were irradiated with different exposure periods to microwave (1, 5, 10, 30, 60, 300 and 600 seconds). Various germination traits were estimated and monitored during the experiment at different time-points; 3, 5, 7, 9 and 12 days after sowing (DAS). Based on the obtained results, the percentage of germinated seeds Nk, germination rate Sk (seed.h-1), maximum number of germinated seeds, relative germination coefficient (Wk) were calculated with the using germination formulas by Ciupak et al. (2007) presented in Table (1). Biomass and biomass allocation Shoot and root biomass were determined for Triticum aestivum plants irradiated with 2.45 GHz radiofrequency and the untreated control. Biomass allocation within plants was calculated in g per g (S/R ratio, g.g-1) of total seedling biomass to avoid size effects, and calculated as a mean of three replicas. Data of Biomass allocation and shoot-to-root ratios were assessed statistically in plants irradiated with microwave radiofrequency versus the control ones to evaluate the change in biomass allocation pattern. Statistical analyses Analysis of variance test (ANOVA) followed by Duncans multiple range comparisons were employed to analyse the results of barley after seed irradiation with microwave radiations. Further, correlation and simple linear regression analyses were also performed using SPSS statistical software ver. 22 and Microsoft Excel package 2016 at a confidence level of 95%. Results Seed germination The influence of microwave radiations on various germination dynamics were assessed intensively on the first twelve days after seeds sowings (DAS) in Hordeum vulgare L. plant. Barley seeds were subjected to different exposure doses of microwave radiation from magnetron with 2450 MHz and 800 Watts. Germination indices monitored and assessed are; number of germinated seeds (nk), percentage of germinated seeds (%), germination rate (Sk; seed.h-1), germination index (GI), and the relative germination coefficient (Wk) at different time points 3, 5, 7, 9, and 12 DAS (days after seeds sowing). The percentages of germinated seeds were presented in Figure (1A-E) for different time points. A significant change in the percentage of germinated seeds were observed after seed irradiation with microwave assessed by one-way analysis of variance (ANOVA) followed by Duncans multiple range comparisons. Significant variations were observed versus the untreated control plant group. Letters on figures 1 ( A) to (E) represent the results of Duncans multiple range comparisons, where, different letter mean significant difference (Figure 1). The maximum germination percentage observed were 100% recorded at MW dose of 5 seconds-5 DAS, 1, 5 seconds dose 7,9, 12 DAS. MW radiations observed to have a positive effect on germination at low doses of 1, and 5 seconds (Figure 1) these were assessed statistically by ANOVA and Duncans multiple comparisons. The general trend of MW radiations on seeds germination percentage was strong negative and significant relationship (Figure 3A-E) revealed by both regression and Spearmans correlation i.e. increasing levels of MW radiations caused decrease in germination parameters especially high doses of MW. Other germination indices e.g. germination rate (Sk; seed.h-1) were also recorded at different MW doses and time points (3, 5, 7, 9, 12). Germination rate in the untreated control 0.19 seed.h-1 5 and 7 days after seed sowing while in seeds treated with 1 and 5 seconds of MW the germination rate increased from 0.19 to 0.21 seed.h-1 revealing that not only the germination percentage increased but also the germination rate and speed (Figure 2A-D). Further, early germination was recorded after 1 and 5. Figures 3 (F-I) represent linear regression trend-line for the effect of MW radiation on germination rate, which had a strong inverse significant effect. Relative germination coefficient (Wk) were calculated and normalized to the control germination. Data of relative germination coefficient were presented in Figures (2E-H) at different time points (3, 5, 7,9); respectively. The relative germination coefficient increased after MW irradiation of 1 and 5 seconds (Figure 2E-H), while, Wk was decreased after irradiation with higher doses of MW radiations. Analysis of variance was carried out to assess the different between treatments control and were followed by Duncans multiple range comparisons. Linear regression trend-lines presented in figures (3K-N) represent the linear relationship between MW radiation doses and relative germination coefficient (Wk) after 3, 5, 7, 9 days after seed sowing. Inverse strong significant relationship between increasing doses of MW radiations and Wk. The germination index (GI) followed the same trend with increasing levels of microwave radiations (Figures 1, 3O). Photosynthetic pigments and Growth: Shoot and root biomasses were estimated in Hordeum vulgare L. plants after irradiation to MW radiations. Shoot biomass ranged from 0.03 to 0.42 g/plant-FW where the maximum shoot fresh weight recorded after MW irradiation of 1 second dose and minimum in 600 seconds. MW radiations severely decreased the shoot biomass in barley (Figure, 4A). Root biomass, on the other hand, ranged from 0.03 to 36 g/plant-FW. The highest root fresh weight was recorded at 300 s MW irradiation dose. While minimum root fresh weight were recorded after 600 seconds MW dose (Figure 4B). Whole plant fresh weight ranged from 0.06 to 0.67 g/plant-FW. Shoot, root, and whole plant biomass showed a negative trend with increasing levels of MW radiations revealed by simple linear regression analysis and Spearmans correlation (Figure 7A,B,C). Microwave irradiation induced a significant decrease in shoot, root, and plant biomass in barley plants (Figure 7A,B,C). The behaviour or nutrient allocation was assessed in terms of shoot and root biomass as shoot: root ration (g.g-1) after seed irradiation with MW. Biomass behaviour was allocated toward barely shoot system after irradiation with 1 seconds of MW radiations. While, higher doses of MW induced nutrients to be allocated toward root system (figure 5B, 3O). Leaf chlorophyll contents increased significantly after 1 and 5 seconds of MW irradiations compared to the control (Figure 5A), however, MW doses from 300 and 600 seconds decreased significantly from the untreated control. Plant height was monitored after various MW irradiations doses and showed a significant decrease in response to MW (Figure 5) revealed by Duncans multiple range comparisons versus untreated control plants. Root volumes did not changes significantly with MW radiations except for the 600 seconds dose which showed a significant decrease versus control (Figure 5D) Membrane Ion leakage (%) Electrolyte leakage is a stress-induced injury that commonly used as a measure of plant response and tolerance to stress (Bajji et al., 2002; Lee and Zhu, 2010). MW irradiation with dose 1 and 60 seconds did not induce a change in electrolyte leakage; however, MW doses 5, 10, 30, 300 and 600 seconds significantly increased the electrolyte leakage compared to the untreated control (Figure 6). A strong negative significant relationship between increasing doses of MW radiations and electrolyte ion leakage (R2= 0.84; Pearson Correlation= -0.61; p-value Discussion Microwave irradiation with different exposure doses induced changes in various parameters of barley (H. vulgare genotype Giza-129). Germination parameters were dose-dependent and were stimulated by several exposure doses of microwave radiations. The percentage of germinated seeds, germination rate, relative germination coefficient and germination index at different time points were increased by short exposure to microwave radiations, however, height exposure doses of microwave-induced a significant decrease in germination consequences. Further, various growth parameters were increased by one or more low doses of microwave radiations and were significantly decreased by higher exposure doses. These results were found to be in agreement with (Abu-Elsaoud, 2015; Aladjadjiyan, 2002; CreȆºescu et al., 2013; Ragha et al., 2011). Seed germination is completed with the protrusion of the radicle through the seed coat (Bewley Black, 1994). The subsequent seedling growth involves the e stablishment of the root and shoot systems. The hypocotyl growth is caused principally by cell expansion and/or by elongation. The low power 10.5 GHz irradiation reduces the rate and percentage of germination in radish seeds and increases germination mean time, thus impairing seed germination. The germination reduction is linearly dependent on the MW power intensity incident on the seed. These findings support the simplified hypothesis that the power density on a plane perpendicular to wave direction decreases with the inverse square of the distance from the source. Membrane electrolyte leakage accompanies the plant response to stresses were monitored at different microwave exposure doses. Electrolyte leakage is widely used as a measure of stress-induced injury in plants (Bajji et al., 2002; Lee and Zhu, 2010). According to our results microwave radiation with dose 1 seconds and 60 seconds did not induce a change in electrolyte leakage; however, MW doses from 5 to 600 seconds significantly increased membrane electrolyte leakage compared to the untreated control. These results in agreement with previous results (Aladjadjiyan, 2002; Demidchik et al., 2014). A possible explanation by (Aladjadjiyan, 2002) suggests a hypothesis about the absorption of the microwave radiation energy by the hydrogen or magnesium atoms electrons in the chlorophyll molecule. The energy absorbed is redistributed and it causes changes in the chlorophyll molecule. By increasing the radiation power used for the treatment of the samples, the number of free ions in the extract decreases and hence its electroconductivity, too (Aladjadjiyan, 2002). Studies using patch-clamp method showed that the microwave exposure reduces trans-membrane protein channels opening in cultured chick myotubes probably because microwaves provoked an alteration of intracellular enzymatic processes e.g. protein kinase activation (DInzeo et al., 1988) (DInzeo et al., 1988). In plant cells, the protein of water channels namely aquaporins of vacuolar membranes and plasma membranes are involved in the regulation of water movement dynamics in growth and development of plant cell and in stress responses (Maurel, 1997). In case of radish seedlings, microwaves may reduced water passage across cell membrane blocking aquaporins and causing reduction of growth in a turgor-dependent manner (Scialabba and Tamburello, 2002). The increase of growth rate upon irradiation removal shows that during the elongation growth, the cell can partially repair damages occurred at the membrane level. There is a general consensus of opinion about the fact that MW induces a thermal detrimental effect over the biological system. In the present case, we assume that the damage induced by the low- power microwave exposure is non-thermal because a slight temperature increase (up to 25 oC} over radish seeds has been demonstrated to induce germination and growth increase (Scialabba Melati, 1995). The reduced germination percentage and the delayed seedling growth confirm the importance of a serious cause of concern about the influence of expo- sure to environmental MW fields. It can be stressed the importance of limiting in time the exposure to MW as suggested by the recovering ability of the biological system considered in the present research. Membrane Electrolyte leakage is an essential measure of the plants responses to various stresses. It is mostly associated with the K+ efflux, which is a common response in plant cells (Demidchik et al., 2014). The stress-induced electrolyte leakage is always accompanied by reactive oxygen species (ROS) generation and hence, leads to programmed cell death. Recent results exhibited that reactive oxygen species (ROS; H2O2 and hydroxyl radicals) activates annexins, SKOR and GORK genes that catalyses K+ efflux from plant cells (Demidchik et al., 2014). Further, GORK-genes mediated potassium ion (K+) cause programmed cell death under oxidative stress. The intracellular endonucleases and proteases look to be blocked by potassium ions; consequently, the efflux of these K+ stimulates these nucleases and proteases hydrolytic enzymes causing programmed cell death (PCD). Potassium ions could play a metabolic switch role under moderate stress conditions decreasing the anabolic reactions rate and stimulating catabolic reactions, leading to the release of energy required for repairing and adaptation needs (Demidchik et al., 2014). The effect of microwaves on plants was the main purpose of the current study. Since it is a known problem, many other pieces of research were done on this topic. Having seen and observed other projects, we noticed that the major conflict was between whether microwaves affect plants germination or not. Our hypothesis was that they do affect it and, of course, it is well known that they do but it still made a challenge trying to prove it and it was found that every single step affected the results. Since it is likely that other people who did similar projects have done some errors through their study, the results were not reliable and could not be considered accurate enough.
