Iris yellow spot virus (IYSV; family Bunyaviridae, genus Tospovirus) is an economically important viral pathogen of onion vectored by onion thrips (Thrips tabaci Lindeman). Rapid spread of IYSV has occurred in the western United States and Georgia, with recent reports of IYSV from New York in the northeastern United States (1). In June and mid-July of 2007, symptomatic plants were found in Ontario, Canada in onions grown from sets in a home garden in Grey County (44°27′N, 80°53′W) and on a small commercial farm in Ottawa-Carleton County (45°14′N, 75°28′W), respectively. In the home garden, bleached, elongated lesions with tapered ends occurred on middle-aged leaves of 30% of 100 plants. By August 2007, 91% of these plants were symptomatic. In Ottawa-Carleton, two lesions with green centers and yellow borders occurred on a single leaf of a single plant in a field of 1,120 plants. Symptomatic leaf tissue tested positive for IYSV by IYSV-specific antiserum from Agdia Inc. (Elkhart, IN) in a double-antibody sandwich (DAS)-ELISA. These two isolated and remote finds of IYSV in Ontario prompted a survey in early August of 2007 of the Holland Marsh (44°5′N, 79°35′W), the largest onion-producing region in Ontario. Nine onion fields separated geographically across the Holland Marsh Region were scouted and one to three samples of symptomatic tissue per field were analyzed by DAS-ELISA. IYSV was confirmed in seven of nine (78%) fields surveyed and in 13 of 16 (81%) of the individual samples. A reverse transcription (RT)-PCR assay was used to verify the presence of IYSV in one new symptomatic tissue sample per field collected from three of the fields where IYSV was confirmed by ELISA. Primers specific to the small (S) RNA of IYSV (5′-TAA AAC AAA CAT TCA AAC AA-3′ and 5′-CTC TTA AAC ACA TTT AAC AAG CAC-3′) were used (2). The resulting 1.2-kb amplicon, which included the 772-bp nucleocapsid (N) gene was cloned and sequenced. Sequence analysis showed that the N gene of the Ontario isolate (GenBank Accession No. EU287943) shared 92 to 98% nucleotide sequence identity with known IYSV N gene sequences. The highest nucleotide sequence identity (98%) was with Genbank Accession Nos. DQ233475 and DQ233472. To our knowledge, this is the first report of IYSV infection of onion in Ontario and Canada. This finding confirms further spread of the virus within North America and the need for research to develop more effective management options to reduce the impact of IYSV on onion production. The finding of IYSV in remote and isolated locations where onions were grown from sets implies that the spread of IYSV via infected bulbs warrants further investigation as a potentially important route of distribution of the virus.

Poplar is popular among farmers and planted widely in the form of block and boundary systems. The preferences of farmers are shifting much more towards bund plantations due to their smaller yield reductions and can take up kharif and rabi crops till rotation. As for boundary plantations, farmers tend to grow trees in any direction without concern for yield reduction or profitability. Against this background, an experiment was designed by planting poplar at 2 m intervals in East–West (E–W) and North–South (N–S) directions during 2008 to determine the production potential and economic viability of boundary plantations and their effect on sorghum (Sorghum bicolor) and wheat (Triticum aestivum) crop rotations till harvesting of the trees. The experiment comprised three variables: stand age (years); four aspects (northern and southern E–W rows, eastern and western N–S rows; these four aspects are considered by dividing the tree lines); and six distances from tree the lines (0–3, 3–6, 6–9, 9–12, 12–15, 15–18 m and a control). A split-split plot design with three replicates was used. A significant reduction of fodder biomass of sorghum and wheat yield was observed up to 9 m distant from the tree line: the reduction was 10 to 60% for the kharif season and 7.2 to 29.5% for rabi crops from the second year to eight years after planting, respectively. Interestingly, the poplar boundary plantation had a favorable microclimatic effect from 9 to 15 m distance from the tree line, which increased crop yields compared with the control. The total dry wood production of poplar in the E–W direction (166.99 mg ha−1) was almost two times more than production for the N–S direction (82.62 mg ha−1) at 8 years of rotation. The economic analysis of this study concluded that an E–W boundary plantation of poplars exhibited the maximum net returns of INR 549,367 ha−1, a net present value of INR 222,951 ha−1, a BC ratio of 1:1.65, an IRR of 85% and an LEV of INR 1,220,337 ha−1. Therefore, it is concluded that the intercropping of a sorghum-wheat crop rotation in E–W boundary plantations was more beneficial for enhancing farm income over traditional agriculture in north India.

AbstractThe work performance of two teams of four donkeys (heavy, 680 kg and light, 460 kg) and one pair of Jersey crossbred oxen (646 kg) was compared when they ploughed 4 hi day on four types of soil (clay, redsoil, sandy soil and sandy clay) using two types of plough, a conventional ox plough (40 kg) and a lighter prototype, the ‘Walco’ plough (32 kg) on an experimental farm. Work parameters were also measured with farmers’ cattle and donkey teams ploughing on f arms in Matobo and Nkayi districts. Working speed, power and effective field capacity (ETC) were higher for the ox-team (1·03 m/s, 920 W and 14·5 h/ha for the conventional plough and 0·99 m/s, 745 W and 13·9 h/hafor the Walco plough) and the heavier donkey team (0·87 m/s, 689 W and 14·2 h/hafor the conventional plough and 0·87 m/s, 787 W and 17·3 h/hafor the Walco plough) than for the lighter donkey team (0·59 m/s, 461 W and 22·1 h/hafor the conventional plough and 0·64 m/s, 445 W and 23·4 h/hafor the Walco plough). Expressed as a proportion of live weight or metabolic live weight there were no significant differences in draught forces exerted between teams but power output per unit live weight was greater in the ox-team than in the light donkey team but similar to that in the heavy donkey team. The Walco plough required a lower force (742 N) to operate than the conventional plough (816 N) but apart from this did not have any marked advantages over the conventional plough. On-farm, team sizes of donkeys varied from three to seven animals (team weight 340 kg to 1007 kg) and cattle team sizes from two to four animals (team weights 558 to 1709 kg). Regardless of team number, the heavier teams tended to out-perform the lighter teams (speed range 0·63 to 1·08 m/s, power 395 to 1136 W, EFC 9·1 to 25 h/ha)) with one exception, a well trained team of two oxen (team weight 879 kg, speed 1·02 m/s, power 775 W, EFC 9·1 h/ha). Donkeys tended to plough at a slower pace than oxen, with a lower power output, although when weight differences between teams were equalized (four heavy donkeys compared with two oxen), then there was little to chose between the species. Results suggested that teams of three or more donkeys can effectively be used for ploughing on the soils tested. The results highlighted the importance that team live weight and training/experience have in determining work performance.

Finally here comes a volume modestly entitled Tolkien and the First World War. On the threshold of Middle-earth. This is the result of many years of study by the author, John Garth, who writes in the introduction: This biographical study was born from one observation: how strange that J.R.R. T o l k i e n b e g a n t o c r e a t e h i s m o n u m e n t a l m y t h o l o g y i n t h e m i d s t o f t h e F i r s t W o r l d W a r, [emphasis added — J.Z.L] that disappointing crisis that shaped the present day. This sentence may surprise the Polish reader, whose consciousness has shaped a completely different image of the First World War, as an event that may have been a crisis, but gave Poland the independence it had been dreaming of for over a hundred years. Meanwhile, for the generation to which Tolkien belongs, it was just that — a crisis. As Hermann Broch, who was slightly older than him, wrote about this war: “Goodbye Europe, beautiful tradition is over”. Garth shows how Tolkien contrasted his work with this perception of the experience of the Great War, a work that is a great mythical story about destruction but also about hope. At the same time, it is a tribute to the memory of the generation that died in the trenches of Flanders.

The present study was conducted during October 2014 to June 2015 in the farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to find out the most effective management option (s) against brinjal shoot and fruit borer (BSFB) with 6 treatments namely, Beauveria bassiana, 1´109 CFU @ g l-1, Bioneem 0.3 EC (Azadirachtin) @ 1.5 ml l-1, Tracer 45 SC (Spinosad) @ 0.4 ml l-1, Vertimec 1.8 EC (Abamectin) @ 1.2 ml l-1 of water, Mechanical control (hand picking) with clean cultivation and untreated control. Results revealed that shoot infestation at pre-fruiting stage was the lowest in Bioneem 0.3 EC (4.34%) and at fruiting stage in Tracer 45 SC treated plot (7.75%) and the highest was in untreated control plot (17.94% at pre-fruiting stage and 39.46 at fruiting stage). The lowest fruit infestation by BSFB was obtained with Tracer 45 SC (8.16% n/n and 10.0% w/w) followed by B. bassiana, 1´109 CFU (23.23% n/n and 18.27% w/w) and the highest infestation was observed under untreated control plot (48.59% n/n and 32.09% w/w). Percent reduction of infested fruit by number (83.21%) and weight (68.84%) over untreated control was higher in Tracer 45 SC treated plot resulting significantly higher marketable yield. Therefore, the significant highest marketable yield (34.39 t ha-1) was harvested in the plot treated with Tracer 45 SC followed by 22.78 t ha-1 with B. bassiana, 1´109 CFU and 19.26 t ha-1 from Vertimec 1.8 EC treated plot. The highest benefit cost ratio of 3.05 was obtained from Tracer 45 SC followed by 2.93 in B. bassiana, 1´109 CFU and 2.89 with Vertimec 1.8 EC sprayed plot.Bangladesh J. Agril.

AbstractLimited nutrient availability is one of the major challenges in organic farming. Little is known about nutrient budgets of organic farms, the underlying factors or effects on soil fertility. We therefore assessed farm gate nutrient budgets for nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulfur (S) of 20 organic farms in Germany and analyzed their soil nutri-ent status. In average, the budgets showed a surplus of N (19 kg ha−1), K (5 kg ha−1), S (12 kg ha−1), and Mg (7 kg ha−1), and a deficit of P (−3 kg ha−1). There was, however, high variability between farms (e.g. standard deviation up to ± 36 kg N ha−1), which was mainly explained by different degrees of reliance on biological N fixation (BNF) as N source. When farms obtained more than 60% of their N input through BNF, they had deficits of P (mean −8 kg P ha−1) and K (mean −18 kg K ha−1). Nutrient status of most soils was within the ad-vised corridor, but for P, K and Mg, 10–15% of fields were lower and 45–63% were higher than advised. Extractable soil nutrient contents did not correlate with the nutrient budgets, inputs or outputs. Only extractable soil P increased with increasing P inputs and outputs. Fur-thermore, a decrease in extractable soil P was detected with a prolonged history of organic farming, indicating a risk of soil P mining in organic farming systems. In conclusion, the study revealed nutrient imbalances in organic farming and pointed to P and K scarcity as a major challenge for organic farms with high reliance on BNF in the long term.

The field experiments were conducted in rabi seasons of 2014-15 and 2015-16 at research farm, Ludhiana, Punjab. Wheat variety (WH 1105) was sown in two row directions viz, east-west (E-W) and north-south (N-S) with three row spacing as S1 (15 cm), S2 (22.5 cm) and S3 (30 cm), and two mulching levels viz., Mo (No mulch) and M1 (mulch at the rate of 5t ha-1). PAR interception, canopy temperature, soil temperature and soil moisture were recorded periodically during the crop season in all the treatments. The results revealed that the intercepted photosynthetically active radiation (PAR) was 4- 5 per cent higher in E-W than N-S row direction which contributed 1.67 q ha-1 higher grain yield. Better utilization of solar radiation was observed in 15.0 cm row spacing and the canopy temperature was 0.5°C higher in unmulched crop as compared to mulched crop during both years. Straw mulching @ 5t ha-1 improved soil moisture and regulated soil temperature. Mean soil temperature was higher (1.0 ºC) under mulched crop as compared to unmulched crop. The soil moisture was 4-5 per cent higher under mulched crop as compared to unmulched crop which ultimately resulted in higher soil temperature during early growth stages. Significantly higher grain yield was recorded in mulched crop as compared to unmulched.

Cattle behavior and grazing distribution is probably related to the available food, although it could also be influenced by the canopy shade, ambient temperature and access to water. The objective of this study was to evaluate the interaction among tree cover (TC) and cattle positions (CP) when searching for food and comfort areas, under warm and hot weather, in a silvopasture system. Analyses were conducted on Pajonales farm, located in the municipality of Ambalema (lat. 4° 45’ 25.9” N; 74° 52’ 20.8” W) in Colombia, from December 2009 to January 2010. The farm has an average elevation of 300 masl. Mean precipitation is 1270 mm.year-1, and temperatura 28°C. The pasture used for this study had an area of approximately 54 ha, with topography from flat to gently sloping. TC was determined from digital orthophotos QuickBird using ArcGIS® 9.1. The paddock was segmented into a 0.25 ha grid cell lattice and all sapling canopies within grid cells and animal movement were mapped.Six cows (3 Brahman and 3 F1, Brahman x Holstein) equipped with GPS-collars (Garmin eTrex-Vista) configured to record and store position, were tracked during 60 days at 5‐min intervals. Average values indicate that cows, generally, traveled greater distances in warm period (7.4 km) and 6.1 km in the hot period. Cows prefer areas with low TC (˂ 20%) and intermediate TC (20-40%); these areas had more biomass of fodder dry matter. The study is an important contribution to understanding the dynamics of animals in search for food under grazing conditions.

All-solid-state-batteries (ASSBs) have long promised to be the next-generation of high-performance energy storage devices, with a step-change in energy density, stability and cell safety touted as potential advantages compared to conventional Li-ion battery cells.[1] The development of fast lithium-ion conductors is key to realising commercially-viable ASSBs, however significant challenges remain with the leading candidate materials. Complex metal hydrides, in particular BH4 - derived materials, have gained recent attention due to their high ambient temperature lithium ionic conductivities and good stability with lithium metal.[2] Nitrogen-based complex hydrides, such as materials within the Li-N-H system, have largely been studied as solid-state hydrogen stores. However, a key characteristic that links the impressive properties of the Li-N-H system in this application is the high Frenkel defect-based Li-ion conductivity, which facilitates the formation of amide-imide and imide-nitride-hydride antifluorite structured solid solutions.[3,4] These solid solutions represent an opportunity through careful stoichiometry control to tailor the properties of a Li-N-H based material for application as a solid electrolyte. Careful characterisation using X-ray diffraction and Raman measurements have allowed us to evaluate the structure of the solid solutions between lithium imide (Li2NH), lithium amide (LiNH2) and lithium nitride hydride (Li4NH), all dominated by a disordered anti-fluorite phase. We demonstrate the ability to tailor the conductivity of these materials between an ionic insulator and a superionic conductor by simple stoichiometry control. Lithium imide, and stoichiometries close to this compound, in particular display favourable properties as solid electrolyte materials. We herein exhibit the first demonstration of a Li-N-H material in an ASSB, with the materials displaying high lithium ion conductivities, wide electrochemical stability windows and potential for further tuning for this application. Ultimately, these results identify Li-N-H based complex hydrides as an interesting avenue of research for solid electrolyte application that is yet to be fully explored. We hope this presentation will highlight these materials and spark further development such as has been seen for oxide and sulphide based fast-ion conductors. 1) Z. Zhang, Y. Shao, B. Lotsch, Y.

Abstract The aim of study was to investigate the effect of nutrient solution leakage during plant cultivation in greenhouse on soil pollution. Investigations were conducted in horticultural farms in the Wielkopolskie province (Greater Poland), specializing in soilless plant cultivation in greenhouse. In the first farm located on sandy soil tomato has been grown since its establishment (Object A). Prior to the beginning of crop culture soil samples were collected for analyses at every 0.2 m layer, to the depth of one meter. Successive samples were taken also in autumn after the completion of 1, 2, 3 and 7 culture cycles. For comparison, research was also conducted in a greenhouse located on loamy sand/sandy loam soil used for 8 years for tomato culture (Object B). In all these facilities plants in rockwool were grown and the fertigation in an open system was provided. Chemical analyzes showed the dynamics of soil properties changes and vertical distribution of cations and anions within the soil profile. Increased content of almost all nutrients and particularly of S-SO4, P, K, Zn, N-NH4, N-NO3 in the soil profile in object A and S-SO4, K, P, N-NO3 in the soli profile in object B were recorded. The results showed that the degradation rate of the soil environment as a result of open fertigation system application depends primarily on the duration of greenhouse operation. However, explicit changes in the chemical properties of soils were observed already after the first growth cycle. Smaller doses of fertilizers and water, and in consequence reduction of nutrients losses may be achieved by closed fertigation systems.

ENGLISH ABSTRACT: This study examines the presentation of race relations in two Sesotho novels written after 1994. The purpose of the study is to establish whether or not post-apartheid Sesotho novels present race relations as they were presented during the apartheid era. The novels of focus are, N.S. Zulu's Nonyana ya Tshepo (The bird of hope) (1997) and T.W.D. Mohapi's Lehfaba fa fephako (The pain of hunger) (1999). The manner in which the authors who wrote during the two distinct eras presented the issue of race and presented race relations will be the focal point. At the end of this study it should be clear whether or not authors after 1994, that is, after the apartheid era continue to present race relations in an idealistic manner. During the apartheid era authors such Lesoro (1968) and Mophethe (1966) were very cautious when presenting race relations in their novels. The common factor in these novels is the portrayal of the white Afrikaner characters by the authors. White characters were portrayed as very merciful, good Samaritans and their relationship with their black counterparts were often harmonious and crisis free. Attributes of race such as racial discrimination, racial hatred, racial conflict and racial intolerance were seldom spoken about in those novels. This is reminiscent of the notorious apartheid laws, which prohibit freedom of press. White characters in some novels published during the apartheid era were not characters derived from real life. In N.S. Zulu's novel, Nonyana ya Tshepo we examine the portrayal of the characters from the two distinct races, black Africans and white Afrikaners. The author portrays the two groups of characters to be what Scholes (1981 :11) calls characters representative of a social class, race and a profession. Black characters are portrayed as the exploited, which are always inferior, submissive and subjected to racial discrimination by their white counterparts. White Afrikaners are portrayed as the exploiters, who are superior, oppressors and the ones who further the policy of apartheid. This state of affairs prompted the black Africans to develop hatred towards the Whites. Instead of idolizing their masters, Blacks do the opposite. Our main character, Tshepo who is said to be fathered by the white Afrikaner, is marginalized by his fellow Blacks and declared an outcast. In T.W.D. Mohapi's novel, Lehlaba la lephako, the main character, Seabata who lusts for power and wealth is seen struggling for both at the expense of his fellow black Africans. Seabata is used by his white boss, Sepanapodi, to maintain the legacy of apartheid. The narrator portrays Seabata in such a way that he could carry out his boss' mission. Seabata is power hungry and always likes to please his boss to attain that, even if that means creating enmity with his own black people. Seabata's socio-economic status makes him vulnerable to manipulation by Sepanapodi. Seabata was advised by his father that he should always strive to please his master in order to gain glory and wealth. He followed the advice slavishly and that left him devastated. He found himself at loggerheads with his colleagues, with the pastor, Nkgelwane, with a local teacher, Mohanelwa and with his wife, Mmabatho. Conflict between Seabata and the community is caused by the pain of hunger.
AFRIKAANSE OPSOMMING: Die doelstelling van hierdie studie is om ondersoek in te stel of die twee Sesotho novelles wat na 1994 geskrywe is, die verhouding tussen verskillende rasse behandel. Die doel van die studie is om uit te vind of die Sesotho novelles wat gedurende die tydperk van apartheid die aanbieding van rasse-verhouding dek, soos wat dit aangewys was gedurende die tydperk van apartheid. Die ondersoek sal gedoen word met die vergelykking van twee novelles wat na 1994 geskrywe is, d.w.s. N.S. Zulu se Nonyana ya Tshepo en T.W.D. Mohapi se Leh/aba /a /ephako . Die manier waarop die twee skrywers wat gedurende die twee afsonderlike tydperk, die kwessie van rasse behandel, en hoe hulle dit aangebied het, sal die fokuspunt wees. Aan die einde van hierdie studie moet dit duideliker word aan die lesers tot watter mate die skrywers wat na 1994 geskryf het, d.w.s na die apartheid tydperk, nog die rasse-verhouding op 'n idealistiese manier aangebied het. Die skrywers wat gedurende die apartheid tydperk geskrywe het, soos Lesoro (1968) en Mophethe (1966) was baie versigtig toe hulle die rasse-verhouding in hulle novelles aangebied het. Die gewone faktor van hierdie novelles is die uitbeelding van die wit Afrikaners se karakters deur die skrywers. Wit karakters is altyd as baie barmhagtig, en as goeie Samaritane beskrywe, en hul verhouding teenoor hulle swart teenhangers is dikwels eensgesind en vry van krisis uitgebeeld. Die hoedanigheid van rasseonderskeiding wat rassehaat, rasse in stryd met mekaar, en rasse onverdraagsaamheid, is in daardie tyd seide van geskryf in die novelle. Dit herinner die leser aan die ongunstige apartheidswette wat nie vryheid van die pers toegelaat het nie. Wit karakters, in sommige novelle wat gedurende die tydperk van apartheid gepubliseer is, is nie karakters wat van die ware lewe afgelei is nie. In N.S. Zulu se novelle, Nonyana ya Tshepo word 'n uitbeelding gemaak van karakters van die twee afsonderlike rasse, die swart Afrikaners en die wit Afrikaners. Die skrywer beeld die twee groepe van karaktes as die wat Scholes (1981 :11) noem die wat verteenwoordigend van 'n sosiale klas, rasse en beroep is. Swart karakters is beskrywe as diegene wat geeksploiteer word, wat altyd as minderwaardige, onderworpe en mindere rasse beskou word. Hulle word gediskrimineer deur hulle wit landgenote. Wit Afrikaners is beskou as die eksploiteerders, wat die voortreflike onderdrukkers is en wat wat die beleid van apartheid laat voortgaan. Hierdie toestand het die swart Afrikaners gelei om haat te ontwikkel teenoor die Wittes. In plaas van om hulle meesters eer te bewys, het die swart Afrikaners die teenoorgestelde gedrag. Die hoofkarakter, Tshepo, wat geglo is dat hy kind van die wit Afrikaner is, is deur sy mense verban en as verworpeling verklaar. In T.W.D. Mohapi se novelle, Lehlaba la lephako het die hoofkarakter, Seabata, begeertes van mag en rykdom. Hy word opgelei as 'n stryder op koste van sy medemense, swart Afrikaners. Seabata is deur sy wit meester, Sepanapodi misbruik om die nalatenskap van apartheid te handhaaf. Die verteller beeld Seabata af op so 'n manier dat dit duidelik is dat Seabata sy baas se opdrag sou voortdra. Hy, Seabata het 'n wens om mag te he en bo alles om sy baas tevrede te stel op koste van ander swart Afrikaners, al maak dit hom 'n vyand van sy mense. Seabata se sosiale status het hom laat kwesbaar ge stel teenoor Sepanapodi se manipulasie. Sy vader het hom advies gegee dat hy altyd sy meester moes bevredig ter wille van glorie en rykdom. Hy het toe die advies van sy vader slaafs nagevolg, daarom het dit hom in 'n neerdrukkende gevoel laat eef. Aan die einde is hy in 'n konflik met andere soos sy kollegas, die plaaslike predikant, Nkgelwane, die onderwyser, Mohanelwa en sy vrou. Die stryd wat Seabata met al die mense in die gemeenskap het, is die oorsaak van hongersnood.

The increased automation of the car manufacturing process, in which much of the assembly has been delegated from man to machine, has done much to relieve workers of the burden of heavy lifting. However, despite ergonomic improvements in the workplace, many jobs still require workers to perform repetitive tasks [1]. In the automotive industry, Work-related Musculoskeletal Disorders (WMSD) are one of the most common occupational problems due to repetitive working tasks. Workers that perform manual work are often prone to awkward postures, repetitive movements, forceful exertions, and overextensions, which are some of the main factors for the arising of WMSD [2]. Besides, these work-related factors, also the personal factors contribute to the occurrence of this kind of injury, making WMSD a complex condition that involves contributions from many factors [3,4]. The current study aims to compare different observational methods commonly used to assess the WMSD risk in repetitive tasks. To accomplish this goal a case of study in assembly workstation of an automotive company in Portugal was applied. It was selected methods that are widely used by ergonomists and are validated for implementation in the industry [5,6]. Therefore, the following methods were applied to an assembly workstation: (i) Rapid Upper-Limb Assessment (RULA), (ii) Occupational Repetitive Actions (OCRA), (ii) Key Indicator Method – Manual Handling Operations (KIM-MHO), and (iv) Revised Strain Index (RSI) This multi-method approach was very important, as it allowed for a more comprehensive assessment, which will support the proposals for improvement The results show that workstation present a considerable WMSD risk in 3 of 4 methods applied. These results suggest that a change to the workstation is necessary. A possible solution would be to implement a Human-robot collaboration solution, in order to reduce the physical demands associated with repetitive movements [7] to which workers are subjected.
