The nap is not a psychosomatic relaxation, but it is certainly a way to become aware of the need to practice a real relaxation session. That is why it should be part of our daily life. Many people believe that napping absolutely implies sleep. This is not true! The nap is essentially a rest of the brain. It implies a mental relaxation following a physical relaxation. It is not necessarily practiced in a lying position, it simply implies the ability to relax the muscles as much as possible and to be able to clear the mind. The siesta is therefore closer to relaxation than to sleep. The body must allow itself regular periods of rest. This prevents it from accumulating too much fatigue and also allows it to resume its activities more efficiently. This short, but deep relaxation appears to be a measure to avoid nervous fatigue. Recent studies have already proven that napping seems to have a protective effect on cardiovascular diseases.

There are certain products that are indispensable to civilized man and whose very use is a proof of civilization. Soap is one of these products. We recall here the famous words of liebig, who maintained that a people is all the more civilized and comfortable, the more soap it uses. This fact is materially well established by the dry figures of statistics. In ancient times, even up to the Middle Ages, soap was completely unknown or very little used. People were content with perfuming their clothes and bodies with odorous substances. The question of which people invented soap making is one that cannot be answered with precision. It seems that in the Middle Ages, in some countries, an alkaline solution was used to wash clothes, and to clean fine sheets, certain plant roots were marinated in water, which formed a foamy liquid (saponaria, saponaria). Despite the progress made by industrial chemistry, we still find some areas where the preparation of soap is the same as our ancestors did a thousand years ago: tallow, lime and wood ashes.

MAN HAS BEEN IMPROVING PLANTS SINCE AGRICULTURE FIRST EXISTED. THIS IS HOW MOST OF THE WRITINGS ON THE HISTORY OF PLANT IMPROVEMENT BEGIN. IN FACT, IT WOULD SEEM THAT MAN HAS ALWAYS TRIED, MORE OR LESS CONSCIOUSLY, TO PRESERVE THE SEEDS OF THE BEST PLANTS FOR LATER SOWING. WITHOUT KNOWING IT, OUR ANCESTORS PRACTICED WHAT IS NOW CALLED "MASSAL SELECTION". HOWEVER, TEN CENTURIES LATER, THE OBSERVATION OF THE POOR RESULTS OBTAINED REVEALS THE INACCURACY OF THIS FIRST STATEMENT. MAN HAS IN FACT ONLY JUST SUCCEEDED IN DOMESTICATING THE MAIN PLANTS CURRENTLY CULTIVATED BY TRANSFORMING PLANTS THAT ARE PERFECTLY ADAPTED TO THE NATURAL ENVIRONMENT INTO PLANTS THAT ARE USEFUL FOR HIM BUT OFTEN UNABLE TO SURVIVE ON THEIR OWN.GMO (GENETICALLY MODIFIED ORGANISM) HAS BECOME A RATHER PEJORATIVE ADJECTIVE, OFTEN CONFUSED WITH (AND LIMITED TO) CORN THAT IS INSENSITIVE TO A HERBICIDE OR AN INSECT, AND EVEN ATTRIBUTED TO EVERYTHING DERIVED FROM IT, FROM CORNFLAKES TO STARCH, IF NOT TO THE MILK OF COWS THAT HAVE CONSUMED IT.

The role of small and medium-sized enterprises in the economy is significant and their adaptation to their economic environment, their survival as well as their success represent important stakes for several actors. The changes in the economic environment that small and medium-sized enterprises face require them to optimize the allocation of their resources in order to ensure their growth. Many researchers agree that a company's performance depends on the effective management of its assets. With respect to the financial management behaviors of owner-managers, several studies on the causes of SME failure have shown that the adoption of financial management practices can make all the difference between failing and financially healthy firms.

Há certos produtos que são indispensáveis ao homem civilizado e cuja própria utilização é prova de civilização. O sabão é um destes produtos. Recordamos aqui as famosas palavras de Liebig, que afirmava que um povo é tanto mais civilizado e confortável, quanto mais sabão usa. Este facto é materialmente bem estabelecido pelos números secos das estatísticas. Nos tempos antigos, mesmo até à Idade Média, o sabão ou era completamente desconhecido ou muito pouco utilizado. As pessoas contentavam-se em perfumar as suas roupas e corpos com substâncias perfumadas. A questão de que pessoas inventaram a fabricação de sabão é uma questão que não pode ser respondida com precisão. Parece que na Idade Média uma solução alcalina era utilizada em alguns países para lavar roupa, e para limpar lençóis finos, certas raízes de plantas eram marinadas em água, que formava um líquido espumoso (saponaria, saponaria). Apesar dos progressos feitos pela química industrial, ainda encontramos algumas regiões onde o sabão é preparado da mesma forma que era pelos nossos antepassados há mil anos: sebo, cal e cinzas de madeira.
